Introduction: and objective: Tremor is a disabling symptom of PD that usually responds poorly to available standard pharmacological agents. This study aimed to assess the effect of Zonisamide 25 mg on tremor in tremor-dominant PD patients as compared to placebo.Methods: This was a randomized, placebo-controlled, double-blind study. Parkinson's disease patients were allocated either to the intervention group (standard treatment along with Zonisamide 25 mg add-on) or the placebo group (standard treatment along with placebo). Baseline Unified Parkinson's Disease Rating Scale (UPDRS) and Tremor Research Group Essential Tremor Rating Scale (TETRAS) scores, as well as accelerometric tremor analysis were done and follow-up assessments of the same were done after 12 weeks of intervention. Percentage change from baseline in the UPDRS tremor score was the primary outcome whereas percentage change from baseline of total UPDRS score, UPDRS rigidity and bradykinesia scores, TETRAS score, and accelerometric tremor analysis values were the secondary outcomes.Results: There was no significant difference in the percentage change from baseline UPDRS tremor scores between the two groups (placebo: 8.33 [-19.89-23.86] vs drug: 26.14 [-35.58 to -16.07], p-value: 0.164, CI: 0.157-0.171). Best-case analysis for missing values showed a significant improvement in the drug group, compared to the placebo group (p-value: < 0.001, CI: <0.001 - <0.001).Conclusion: Zonisamide at a dose of 25 mg per day did not improve tremor in tremor-dominant PD patients, however, a positive trend was seen as compared to Placebo in the UPDRS tremor score. Larger studies are required to confirm this finding. [ABSTRACT FROM AUTHOR]

Study Question: For couples with unexplained subfertility and a poor prognosis for natural conception, is 6 months expectant management (EM) inferior to IUI with ovarian stimulation (IUI-OS), in terms of live births?Summary Answer: In couples with unexplained subfertility and a poor prognosis for natural conception, 6 months of EM is inferior compared to IUI-OS in terms of live births.What Is Known Already: Couples with unexplained subfertility and a poor prognosis are often treated with IUI-OS. In couples with unexplained subfertility and a relatively good prognosis for natural conception (>30% in 12 months), IUI-OS does not increase the live birth rate as compared to 6 months of EM. However, in couples with a poor prognosis for natural conception (<30% in 12 months), the effectiveness of IUI-OS is uncertain.Study Design, Size, Duration: We performed a non-inferiority multicentre randomized controlled trial within the infrastructure of the Dutch Consortium for Healthcare Evaluation and Research in Obstetrics and Gynaecology. We intended to include 1091 couples within 3 years. The couples were allocated in a 1:1 ratio to 6 months EM or 6 months IUI-OS with either clomiphene citrate or gonadotrophins.Participants/materials, Setting, Methods: We studied heterosexual couples with unexplained subfertility and a poor prognosis for natural conception (<30% in 12 months). The primary outcome was ongoing pregnancy leading to a live birth. Non-inferiority would be shown if the lower limit of the one-sided 90% risk difference (RD) CI was less than minus 7% compared to an expected live birth rate of 30% following IUI-OS. We calculated RD, relative risks (RRs) with 90% CI and a corresponding hazard rate for live birth over time based on intention-to-treat and per-protocol (PP) analysis.Main Results and the Role Of Chance: Between October 2016 and September 2020, we allocated 92 couples to EM and 86 to IUI-OS. The trial was halted pre-maturely owing to slow inclusion. Mean female age was 34 years, median duration of subfertility was 21 months. Couples allocated to EM had a lower live birth rate than couples allocated to IUI-OS (12/92 (13%) in the EM group versus 28/86 (33%) in the IUI-OS group; RR 0.40 90% CI 0.24 to 0.67). This corresponds to an absolute RD of minus 20%; 90% CI: -30% to -9%. The hazard ratio for live birth over time was 0.36 (95% CI 0.18 to 0.70). In the PP analysis, live births rates were 8 of 70 women (11%) in the EM group versus 26 of 73 women (36%) in the IUI-OS group (RR 0.32, 90% CI 0.18 to 0.59; RD -24%, 90% CI -36% to -13%) in line with inferiority of EM.Limitations, Reasons For Caution: Our trial did not reach the planned sample size, therefore the results are limited by the number of participants.Wider Implications Of the Findings: This study confirms the results of a previous trial that in couples with unexplained subfertility and a poor prognosis for natural conception, EM is inferior to IUI-OS.Study Funding/competing Interest(s): The trial was supported by a grant of the SEENEZ healthcare initiative. The subsidizing parties were The Dutch Organisation for Health Research and Development (ZonMW 837004023, www.zonmw.nl) and the umbrella organization of 10 health insurers in The Netherlands.

Background: Patients resuscitated from out-of-hospital cardiac arrest (OHCA) have a high morbidity and mortality risk and often develop post-cardiac arrest syndrome (PCAS) involving systemic inflammation. The severity of the inflammatory response is associated with adverse outcome, with anoxic irreversible brain injury as the leading cause of death following resuscitated OHCA. The study aimed to investigate the anti-inflammatory and neuroprotective effect of pre-hospital administration of a high-dose glucocorticoid following OHCA.Methods: The study is an investigator-initiated, randomized, multicenter, single-blinded, placebo-controlled, clinical trial. Inclusion will continue until one hundred twenty unconscious OHCA patients surviving a minimum of 72 h are randomized. Intervention is a 1:1 randomization to an infusion of methylprednisolone 250 mg following a minimum of 5 min of sustained return of spontaneous circulation in the pre-hospital setting. Methylprednisolone will be given as a bolus infusion of 1 × 250 mg (1 × 4 mL) over a period of 5 min. Patients allocated to placebo will receive 4 mL of isotonic saline (NaCl 0.9%). Main eligibility criteria are OHCA of presumed cardiac cause, age ≥ 18 years, Glasgow Coma Scale ≤ 8, and sustained ROSC for at least 5 min. Co-primary endpoint: Reduction of interleukin-6 and neuron-specific-enolase. Secondary endpoints: Markers of inflammation, brain, cardiac, kidney and liver damage, hemodynamic and hemostatic function, safety, neurological function at follow-up, and mortality. A research biobank is set up with blood samples taken daily during the first 72 h from hospitalization to evaluate primary and secondary endpoints.Discussion: We hypothesize that early anti-inflammatory steroid treatment in the pre-hospital setting can mitigate the progression of PCAS following resuscitated OHCA. Primary endpoints will be assessed through analyses of biomarkers for inflammation and neurological damage taken during the first 72 h of admission.Trial Registration: EudraCT number: 2020-000855-11 ; submitted March 30, 2020 ClinicalTrials.gov Identifier: NCT04624776; submitted October 12, 2020, first posted November 10, 2020.

Objective: Computer-assisted child-focused interventions are expected to improve efficiency and personalization of therapist-led treatments for children and adolescents. However, therapist-led, outpatient interventions using computer assistance are lacking for children with oppositional defiant disorder (ODD) or conduct disorder (CD). The present randomized controlled trial examined the efficacy of individualized computer-assisted social skills training for children with aggressive behavior compared to a resource activation intervention.Method: A total of 100 children aged 6-12 years with a diagnosis of ODD/CD and peer-related aggression were randomly (1:1) assigned to either individually delivered computer-assisted social skills training (ScouT) or an individually delivered supportive resource activation treatment (STARK). The primary outcome was parent-rated peer-related aggression, assessed with the respective scale of the Questionnaire for Aggressive Behavior of Children (FAVK) and measured at pre-assessment and after the 16-week intervention (post-assessment). Further parent-, self-, teacher- and/or clinician-rated outcomes included ODD and CD symptoms, a wide range of behavioral and emotional symptoms, callous-unemotional traits, functional impairment, and quality of life.Results: After correcting for multiple testing, analyses of covariance comparing the efficacy of ScouT to the efficacy of STARK yielded small to moderate treatment effects in favor of the ScouT condition regarding parent-rated peer-related aggression (primary outcome; d = -0.64, 95% CI = -1.05, -0.24), parent-rated callous and uncaring traits, and parent-rated quality of life. However, the analyses did not reveal any significant effects for self- or teacher-rated peer-related aggression assessed with the respective scale of the FAVK (self-report: d = -0.21, 95% CI = -0.69, 0.29; teacher rating: d = -0.17, 95% CI = -0.56, 0.22). Moreover, after controlling for multiple comparisons, no significant effects emerged for the following: parent-, self-, and teacher-rated adult-related aggression; parent-, self-, teacher-, and clinician-rated ODD and CD symptoms; parent-, self-, and teacher-rated emotional and behavioral symptoms; and parent-rated functional impairment.Conclusion: According to parent ratings, school-age children with disruptive behavior disorders and peer-related aggression seem to benefit more from individualized, computer-assisted social skills training than from resource activation treatment. However, this conclusion is limited by the missing effects on the clinician-, self-, and teacher-rated measures.Clinical Trial Registration Information: Treatment of Children With Peer Related Aggressive Behavior (ScouT); https://clinicaltrials.gov/; NCT02143427.

Few clinical trials have evaluated the efficacy of psychotherapy for Intermittent Explosive Disorder (IED). The present study tested the efficacy of a cognitive behavioral intervention (versus supportive psychotherapy) among adults with IED. In this randomized clinical trial, 44 participants with IED (22 men and 22 women) aged 20-55 years completed twelve 50-minute individual sessions of either a multi-component cognitive behavioral intervention for IED (n = 19) or a time equated supportive psychotherapy (n = 25). At baseline, posttreatment, and 3-month follow-up, all participants received the Overt Aggression Scale-Modified, which was conducted by an interviewer who was blind to the participant's study condition. During these visits, participants also completed self-report measures of relational aggression (Self-Report of Relational Aggression and Social Behavior), anger (State-Trait Anger Expression Inventory-2), cognitive biases (e.g., Social Information Processing Questionnaire Attribution and Emotional Response Questionnaire), and associated symptoms (e.g., Beck Depression Inventory). Primary study outcomes were aggressive behavior and anger. Though participants in both treatments tended to improve over time, the cognitive behavioral intervention was superior to supportive psychotherapy in decreasing aggressive behavior and relational aggression. These findings support the efficacy of a multicomponent cognitive behavioral intervention in treating aggression in IED. [ABSTRACT FROM AUTHOR]

Over the past decade, there has been rapid growth in the evidence for programs to prevent or reduce intimate partner violence (IPV)-the most common form of men's violence against women. IPV interventions targeting heterosexual couples have shown significant impact. However, our understanding of how these interventions achieve their impacts on violence-the mechanisms through which change occurs-remains limited. Using data from two follow-up rounds of a randomized controlled trial of the Bandebereho intervention in Rwanda, we constructed conceptually driven structural equation models to represent the processes by which hypothesized mediating variables linked treatment assignment to IPV. We found significant differences in the expected direction between the intervention and control participants on all mediating variables, including men's alcohol use, communication frequency, emotional closeness, frequency of quarreling, and men's attitudes related to gender and violence. Several mechanisms-more positive couple dynamics including emotional closeness and communication frequency; men's gender-equitable attitudes; men's alcohol use-accounted for the largest proportions of the effect of assignment to the Bandebereho intervention on IPV. Overall, our findings highlight that no one particular component is driving the reductions in violence; instead, the multiple components and pathways account for the intervention's effects, suggesting that the holistic nature of the intervention may be integral to its positive impact. The Bandebereho trial from which data was used in this analysis was registered on ClinicalTrials.gov prior to completion ( NCT02694627 ). [ABSTRACT FROM AUTHOR]

Objective: This single-blind parallel design randomized controlled trial evaluated the feasibility and effectiveness of a modified version of the Mother-Infant Transaction Program (MITP) in enhancing Chinese mothers' sensitivity towards their premature infants' physiological and social cues.Methods: Sixty mothers of hospitalized premature infants (mean gestational age = 32.1 weeks; SD = 2.8) were randomly assigned to either the MITP group or the treatment-as-usual control group. The intervention group (n = 30) received four sessions of parental sensitivity training adapted from the MITP, delivered by clinical psychologists before the infants were discharged. The control group (n = 30) received standard care provided by the hospitals. Each dyad was assessed at baseline (Time 1), immediately after intervention (Time 2), and when the infants were at the gestation-corrected ages of 3, 6, 9, and 12 months (Times 3-6). Maternal sensitivity, mother-infant interaction quality, parenting stress, postpartum depression, and mother's perception of infant's temperament were measured at Times 1-4, whereas infants' weight gain and developmental performance were assessed at Times 3-6.Results: The MITP group showed significantly higher maternal sensitivity and better mother-infant interaction quality after completing the training. They also reported less parenting stress and postnatal depression than the control group at Time 2 and subsequent follow-ups. The intervention significantly predicted better weight gain and developmental outcomes in infants across Times 3-6, mediated by maternal wellbeing and interaction quality.Conclusion:  Our results demonstrated the feasibility and effectiveness of this adapted sensitivity training among Chinese mothers with premature infants.

Background: Dietary fish-oil supplementation might attenuate the associations between fine particulate matter (PM2.5) and subclinical biomarkers. However, the molecular mechanisms remain to be elucidated. This study aimed to explore the molecular mechanisms of fish-oil supplementation against the PM2.5-induced health effects.Methods: We conducted a randomized, double-blinded, and placebo-controlled trial among healthy college students in Shanghai, China, from September 2017 to January 2018. A total of 70 participants from the Fenglin campus of Fudan University were included. We randomly assigned participants to either supplementation of 2.5-gram fish oil (n = 35) or sunflower-seed oil (placebo) (n = 35) per day and conducted four rounds of health measurements in the last two months of the trial. As a post hoc exploratory study, the present untargeted metabolomics analysis used remaining blood samples collected in the previous trial and applied a Metabolome-Wide Association Study framework to compare the effects of PM2.5 on the metabolic profile between the sunflower-seed oil and fish oil groups.Results: A total of 65 participants completed the trial (34 of the fish oil group and 31 of the sunflower-seed oil group). On average, ambient PM2.5 concentration on the day of health measurements was 34.9 µg/m3 in the sunflower-seed oil group and 34.5 µg/m3 in the fish oil group, respectively. A total of 3833 metabolites were significantly associated with PM2.5 in the sunflower-seed oil group and 1757 in the fish oil group. Of these, 1752 metabolites showed significant between-group differences. The identified differential metabolites included arachidonic acid derivatives, omega-3 fatty acids, omega-6 fatty acids, and omega-9 fatty acids that were related to unsaturated fatty acid metabolism, which plays a role in the inflammatory responses.Conclusion: This trial suggests fish-oil supplementation could mitigate the PM2.5-induced inflammatory responses via modulating fatty acid metabolism, providing biological plausibility for the health benefits of fish-oil supplementation against PM2.5 exposure.Trial Registration: This study is registered at ClinicalTrails.gov (NCT03255187).

Background: Suboptimal medication use contributes to a substantial proportion of hospitalizations and emergency department visits in older adults. We designed a clinical pharmacist intervention to optimize medication therapy in older hospitalized patients. Based on the integrated medicine management (IMM) model, the 5-step IMMENSE intervention comprise medication reconciliation, medication review, reconciled medication list upon discharge, patient counselling, and post discharge communication with primary care. The objective of this study was to evaluate the effects of the intervention on healthcare use and mortality.Methods: A non-blinded parallel group randomized controlled trial was conducted in two internal medicine wards at the University Hospital of North Norway. Acutely admitted patients ≥ 70 years were randomized 1:1 to intervention or standard care (control). The primary outcome was the rate of emergency medical visits (readmissions and emergency department visits) 12 months after discharge.Results: Of the 1510 patients assessed for eligibility, 662 patients were asked to participate, and 516 were enrolled. After withdrawal of consent and deaths in hospital, the modified intention-to-treat population comprised 480 patients with a mean age of 83.1 years (SD: 6.3); 244 intervention patients and 236 control patients. The number of emergency medical visits in the intervention and control group was 497 and 499, respectively, and no statistically significant difference was observed in rate of the primary outcome between the groups [adjusted incidence rate ratio of 1.02 (95% CI: 0.82-1.27)]. No statistically significant differences between groups were observed for any of the secondary outcomes, neither in subgroups, nor for the per-protocol population.Conclusions: We did not observe any statistical significant effects of the IMMENSE intervention on the rate of emergency medical visits or any other secondary outcomes after 12 months in hospitalized older adults included in this study.Trial Registration: The trial was registered in clinicaltrials.gov on 28/06/2016, before enrolment started (NCT02816086).

Background: Intranasal corticosteroids (INCS) are frequently used to treat OSA syndrome (OSAS) in children. However, their efficacy has not been rigorously tested.Research Question: Do INCS result in improved OSAS symptoms, polysomnography findings, behavior, and quality of life compared with placebo?Study Design and Methods: In this randomized, double-blind, placebo-controlled trial, children with OSAS aged 5 to 12 years (N = 134) were randomized 2:1 to receive 3 months of INCS or placebo. Children in the INCS arm were then re-randomized to receive 9 months of INCS or placebo. Polysomnography, symptoms, and neurobehavioral findings were measured at baseline, 3 months, and 12 months. The primary outcome was change in obstructive apnea hypopnea index (OAHI) at 3 months, available for 122 children. The secondary outcome was OAHI change at 12 months, available for 70 children.Results: Median (interquartile range) age and OAHI at baseline for the entire group were 7.9 (6.3 to 9.9) years and 5.8 (3.6 to 9.7) events per hour. OAHI changes at 3 months (-1.72 [-3.91 to 1.92] events per hour) and 12 months (-1.2 [-4.22 to 1.71] events per hour) were not different between the two groups (P = not significant). OSAS symptoms and neurobehavioral results did not differ between the INCS and placebo groups at 3 and 12 months. The 38 children who received INCS for 12 months reported a significant OAHI decrease from 7.2 (3.62 to 9.88) events per hour to 3.7 (1.56 to 6.4) events per hour (P = .039).Interpretation: In children with OSAS, treatment with INCS did not result in significant polysomnography, neurobehavioral, or symptom changes at 3 and 12 months of treatment. Twelve months of INCS treatment resulted in a statistically significant but not clinically relevant OAHI reduction.Clinical Trial Registration: ClinicalTrials.gov; No.: NCT02180672; URL: www.Clinicaltrials: gov.

Background: To address intraoperative bleeding in cardiac surgery, reducing blood transfusion requirements, is mandatory to achieve effective hemostasis. Hemostatic agents may limit localized persistent bleeding. The introduction of carboxymethyl-chitosan component into the hemostatic agent and the application of the radiation crosslinking technique maintain its capacity for achieving intraoperative hemostasis, thus increasing the clinical utility.Methods: A prospective, noninferiority and randomized controlled clinical trial to compare the safety and efficacy of absorbable macroporous polysaccharide composites (AMPC, treatment group) with compound microporous polysaccharide hemostatic powder (CMPHP, control group) (2:1 ratio) as adjuncts to hemostasis in open surgery. The main indication was used for hemostasis in various traumatic hemorrhage areas, including cardiothoracic, vascular, and general surgery. The primary endpoint was success rate of hemostasis within 300 s (at a 10% noninferiority margin). The secondary endpoint was hemostasis time. Both endpoints were assessed in the modified intention-to-treat (MITT) population. Safety parameters were assessed. This study is fully compliant with the CONSORT statement.Results: Randomized patients in AMPC and CMPHP groups were 168 and 84, respectively. In MITT population, the success rates of hemostasis within 300 s were 98.8% (163 of 165) in AMPC and 94.0% (78 of 83) in CMPHP (treatment difference 4.8% [95% CI -0.57% to 10.20%]). AMPC was thus noninferior to CMPHP. Hemostasis time (median [interquartile range]) with AMPC (87 [52.5, 180] s) was better than CMPHP (110 [54.5, 181] s). Changes in laboratory parameters over time and shifts to abnormal values were typical of surgeries and similar between two groups. No noticeable adverse effects associated with AMPC or CMPHP were observed.Conclusions: AMPC is well tolerated as topical hemostatic agent, noninferior to commercial CMPHP, and exhibits excellent safety. This study provides a novel hemostatic agent which appears to offer significant clinical advantage in various hemorrhage areas. [ABSTRACT FROM AUTHOR]

Introduction: Telerehabilitation may be effective on average but is not equally effective among all people with multiple sclerosis (MS). Thus, the purpose of this secondary analysis of a randomized controlled trial was to explore whether baseline characteristics of participants with MS influence fatigue and physical activity outcomes of three telerehabilitation interventions.Methods: Participants were randomized to contact-control intervention (CC), physical activity-only intervention (PA-only), and physical activity plus fatigue self-management intervention (FM+). The 12-week interventions were delivered over the phone. Sociodemographic (age and income), clinical (comorbidities, mental function and physical function), psychosocial (self-efficacy, outcome expectations and goal-setting), and behavioural baseline characteristics (step count and fatigue self-management behaviors) were used in a moderated regression analysis and a responder analysis to examine their influence on the Fatigue Impact Scale (FIS) and Godin Leisure-Time Exercise Questionnaire (GLTEQ) at post-test (i.e. immediately post-interventions).Results: No interactions terms were statistically significant in the moderation analysis. However, the responder analysis showed that baseline psychosocial characteristics and mental function were significantly different (p < 0.05) between responders and non-responders. Specifically, non-responders on the FIS at post-test in the PA-only intervention had significantly lower baseline scores in goal setting for engaging in fatigue self-management behaviours. Also, non-responders on the GLTEQ at post-test in the FM+ intervention had significantly worse baseline scores in mental function.Discussion: Further research is needed to understand the complex relationship among baseline characteristics, telerehabilitation and response heterogeneity. We discuss how research on examining response heterogeneity may be advanced by conducting mega-clinical trials, secondary analyses of big data, meta-analyses and employing non-traditional research designs.Trial Registration: Clinicaltrials.gov (NCT01572714).

Background: Vitamin D supplementation may reduce the risk or severity of infection, but this has been investigated in few large population-based trials. We analyzed data from the D-Health Trial, using prescription of antibiotics as a surrogate for infection.Methods: The D-Health Trial is a randomized, double-blind, placebo-controlled trial in which 21 315 Australians aged 60-84 years were randomized to 60 000 IU of supplementary vitamin D3 or placebo monthly for 5 years. For this analysis, the primary outcome was the number of antibiotic prescription episodes; secondary outcomes were total number of prescriptions, repeat prescription episodes, and antibiotics for urinary tract infection. We estimated incidence rate ratios (IRRs) using negative binomial regression, and odds ratios using logistic regression.Results: Vitamin D supplementation slightly reduced the number of prescription episodes (IRR, 0.98; 95% confidence interval [CI], .95-1.01), total prescriptions (IRR, 0.97; 95% CI, .93-1.00), and repeat prescription episodes (IRR, 0.96; 95% CI, .93-1.00). There was stronger evidence of benefit in people predicted to have insufficient vitamin D at baseline (prescription episodes IRR, 0.93; 95% CI, .87-.99).Conclusions: Vitamin D may reduce the number of antibiotic prescriptions, particularly in people with low vitamin D status. This supports the hypothesis that vitamin D has a clinically relevant effect on the immune system.Clinical Trials Registration: Australian New Zealand Clinical Trials Registry: ACTRN12613000743763. https://www.anzctr.org.au/.

Background: Arterial stiffness and calcification propensity are associated with high cardiovascular risk and increased mortality in chronic kidney disease (CKD). Both magnesium and phosphate are recognized as modulators of vascular calcification and chronic inflammation, both features of CKD that contribute to arterial stiffness. In this paper, we outline the rationale and design of a randomized controlled trial (RCT) investigating whether 24 weeks of oral magnesium supplementation with or without additional phosphate-binding therapy can improve arterial stiffness and calcification propensity in patients with stage 3-4 CKD.Methods: In this multi-center, placebo-controlled RCT, a total of 180 participants with an estimated glomerular filtration rate of 15 to 50 ml/min/1.73 m2 without phosphate binder therapy will be recruited. During the 24 weeks intervention, participants will be randomized to one of four intervention groups to receive either magnesium citrate (350 mg elemental magnesium/day) or placebo, with or without the addition of the phosphate binder sucroferric oxyhydroxide (1000 mg/day). Primary outcome of the study is the change of arterial stiffness measured by the carotid-femoral pulse wave velocity over 24 weeks. Secondary outcomes include markers of calcification and inflammation, among others calcification propensity (T50) and high-sensitivity C-reactive protein. As explorative endpoints, repeated 18F-FDG and 18F-NaF PET-scans will be performed in a subset of participants (n = 40). Measurements of primary and secondary endpoints are performed at baseline, 12 and 24 weeks.Discussion: The combined intervention of magnesium citrate supplementation and phosphate-lowering therapy with sucroferric oxyhydroxide, in stage 3-4 CKD patients without overt hyperphosphatemia, aims to modulate the complex and deregulated mineral metabolism leading to vascular calcification and arterial stiffness and to establish to what extent this is mediated by T50 changes. The results of this combined intervention may contribute to future early interventions for CKD patients to reduce the risk of CVD and mortality.Trial Registration: Netherlands Trial Register, NL8252 (registered December 2019), EU clinical Trial Register 2019-001306-23 (registered November 2019).

Background: Overweight and obesity are typical risk factors for the increased prevalence and incidence of gout. The existing guidelines unequivocally indicated that exercise is highly advantageous for patients with gout. Nevertheless, there is still a lack of specific guidance and clinical evidence. The effects of exercise on improving gout, and the optimal frequency, timing, and types of exercise have not been fully clarified. The present trial aims to determine the effects of a specific aerobic exercise program on body composition in overweight and obese patients with gout.Methods: In this randomized, open-labeled, controlled trial, a total of 60 overweight and obese patients with gout [body mass index (BMI) ≥ 24 kg/m2; age,18-55 years old] are equally randomized (1:1) into two groups (n = 30): moderate-intensity aerobic exercise group (MIAEG), heart rate reserve (HRR) = [(HRmax-HRrest) × 60% intensity] + HRrest, and control group (CG). The moderate-intensity aerobic exercise training program will be conducted for 30-40 min/session and 3 days/week for 12 weeks. Participants in the CG will be asked to avoid making changes in their exercise habits. There will be no limitation in the type of exercise. The primary outcome is the number of patients whose body fat is reduced after 12 weeks. The secondary outcomes include the changes in BMI, waist-to-hip ratio (WHR), insulin resistance index (IRI), serum uric acid (sUA), serum creatinine (SCr), estimated glomerular filtration rate (eGFR), triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), hepatic steatosis, and adverse effects after 12 weeks. One-way analysis of variance (ANOVA) will be used to compare the mean values of normally distributed variables between MIAEG and GC.Discussion: The effect and optimal frequency of exercise for improving the status of overweight and obese patients with gout have not yet been determined. We design a 12-week randomized controlled trial and evaluate the effects of individualized aerobic exercise program on patients with gout. The results may assist such patients with a personalized scientific exercise program based on the disease status and motor abilities, so that patients are prone to exercise under the condition of low risk and achieve the greatest benefits.Trial Registration: ChiCTR2200062153.

Objectives: To evaluate the effectiveness of a question prompt list (QPL) in decision self-efficacy, decision-making participation, patient-physician communication, decisional conflict or regret, and health status in patients with breast cancer.Methods: A total of 240 patients with breast cancer were randomly assigned to a QPL group or control group (n = 120 each). The intervention and control groups received an additional educational QPL booklet and routine care, respectively.Results: The intervention group exhibited significant improvements in decision self-efficacy, perceived patient-physician interactions, and patient-physician communication compared with the control group. Multilevel modeling analyses revealed significant group-time interaction effects on decision self-efficacy (β = 9.99, P < 0.01), perceived patient-physician interactions (β = 8.10, P < 0.01), patient-physician communication (β = 5.02, P < 0.01), and anxiety status (β = -3.78, P < 0.05). The QPL intervention exerted more favorable effects than routine care, with repeated measurements of the same patients and the data of patients under the care of the same surgeons accounted for.Conclusions: The QPL intervention exerted multidimensional effects on decision-making outcomes among patients with breast cancer.Practical Implications: Clinicians can integrate a QPL into routine care for patients with breast cancer.

Background: At present, effectively implementing smoking cessation programs in the health care system constitutes a major challenge. A unique opportunity to initiate smoking cessation focuses on smokers scheduled for surgery. These patients are not only highly motivated to quit smoking but also likely to benefit from a reduction in postoperative complications which may translate into a decrease of costs. Nevertheless, surgical patients are not routinely informed about the benefits of preoperative smoking cessation. Potential reasons for this missed opportunity may be the lack of time and training of surgeons and anaesthesiologists. We therefore aim to analyse the impact of a preoperative high-intensity smoking cessation intervention on surgical complications up to a 90-day postoperative period in patients of various surgical disciplines. The hypothesis is that a preoperative smoking cessation program improves outcomes in smokers undergoing intermediate to high-risk surgery.Methods: The present study is a single-centre, randomized trial with two parallel groups of smokers scheduled for surgery comparing surgery alone and surgery with preoperative smoking cessation. We plan to randomize 251 patients. The primary objective is to compare complications between patients with an institutional multifaceted smoking cessation intervention starting 4 weeks before surgery compared to patients in the advice-only group (control group) within a 90-day postoperative period. The primary endpoint is the Comprehensive Complication Index (CCI®) within 90 days of surgery. Secondary outcomes include the length of hospital stay, cost of care, quality of life, smoking abstinence, and reduction in nicotine consumption.Discussion: The hypothesis is that a preoperative smoking cessation program improves outcomes in smokers undergoing surgery.Trial Registration: BASEC #2021-02004; ClinicalTrials.gov: NCT05192837 .

Background: Measurement of fractional flow reserve (FFR) has an established role in guiding percutaneous coronary intervention. We tested the hypothesis that, at the stage of diagnostic invasive coronary angiography, systematic FFR-guided assessment of coronary artery disease would be superior, in terms of resource use and quality of life, to assessment by angiography alone.Methods: We performed an open-label, randomized, controlled trial in 17 UK centers, recruiting 1100 patients undergoing invasive coronary angiography for the investigation of stable angina or non-ST-segment-elevation myocardial infarction. Patients were randomized to either angiography alone (angiography) or angiography with systematic pressure wire assessment of all epicardial vessels >2.25 mm in diameter (angiography+FFR). The coprimary outcomes assessed at 1 year were National Health Service hospital costs and quality of life. Prespecified secondary outcomes included clinical events.Results: In the angiography+FFR arm, the median number of vessels examined was 4 (interquartile range, 3-5). The median hospital costs were similar: angiography, £4136 (interquartile range, £2613-£7015); and angiography+FFR, £4510 (£2721-£7415; P=0.137). There was no difference in median quality of life using the visual analog scale of the EuroQol EQ-5D-5L: angiography, 75 (interquartile range, 60-87); and angiography+FFR, 75 (interquartile range, 60-90; P=0.88). The number of clinical events was as follows: deaths, 5 versus 8; strokes, 3 versus 4; myocardial infarctions, 23 versus 22; and unplanned revascularizations, 26 versus 33, with a composite hierarchical event rate of 8.7% (48 of 552) for angiography versus 9.5% (52 of 548) for angiography+FFR (P=0.64).Conclusions: A strategy of systematic FFR assessment compared with angiography alone did not result in a significant reduction in cost or improvement in quality of life.Registration: URL: https://www.Clinicaltrials: gov; Unique identifier: NCT01070771.

Background: Prostate cancer is the third most prevalent cancer in the American population. Furthermore, the prognosis is worse in African American as there is increased morbidity and mortality associated with it.Purpose: The purpose of this study is to evaluate the effectiveness of a new online method to educate the patient population regarding prostate cancer risk, diagnosis, treatments, and their decisions about whether to be screened for the early detection of prostate cancer.Methods: Two hundred Black male patients are recruited from different clinical sites and randomized to either the control arm (usual care) or the intervention arm (educational program). We will compare the effectiveness of the intervention to see if patients are discussing the need of getting a prostate-specific antigen (PSA) test, and the possible benefits and harms that may result of having or not having the test, with their primary care providers.Discussion: Shared decision-making (SDM) is the current standard in most cancer-screening guidelines and also a standard of person-centered care. However, there is a lack of evidence-based approaches to improve decision quality in clinical settings and an increased ambiguity of applying SDM for PSA-based screening among Black men in primary care. Our proposal to evaluate a decisional-aid intervention and measure the actual application of SDM during clinical encounters has a high potential to advance the translation path of implementing shared decision-making in clinical settings and provide evidence of the applicability of the guideline in general.Innovation and Overall Impact: Given the 2018 USPSTF updated guidelines recommending shared decision-making about PSA-based screening, the increased risk of prostate cancer mortality in Black men, the challenges of evidence-based decision-making due to the underrepresentation of Blacks in major randomized clinical trials, and implicit racial bias among primary care providers, the time is ripe for interventions to improve shared decision-making about prostate cancer screening in Black men. In this study, we address communication and knowledge gaps between Black men and their primary care providers. The intervention, if proven effective, can be readily scaled across primary care practices across the U.S. and may be adapted to other types of cancer where guidelines have included shared decision-making as well. Early detection of prostate cancer may decrease mortality and morbidity in the long term. [ABSTRACT FROM AUTHOR]

Background and Objective: Zishen Pingchan granule (ZPG), a traditional Chinese herbal recipe for treating Parkinson's disease (PD), is usually used as an add-on drug with some antiparkinsonian drugs in China. The objectives of this study were to evaluate the efficacy, safety, and tolerability of ZPG combined with pramipexole in the treatment of depression in PD (dPD).Methods: A 12-week, multicenter, randomized, double-blind, and placebo-controlled study on ZPG was performed on a total of 200 patients who were treated with pramipexole but still had mild to moderate depressive symptoms. Patients were randomly divided into ZPG (n = 100) or placebo (n = 100). The primary effective result was the mean change from the baseline on the Hamilton Depression Scale 17 items (HAM-D-17) over 12 weeks and the clinical efficacy rate. Secondary endpoints were the mean change from the baseline in the Geriatric Depression Scale (GDS-15), Unified Parkinson's disease rating scale Part III (UPDRS III), Parkinson's quality of life scale (PDQ-8), and Parkinson's disease sleep scale (PDSS-2) over 12 weeks.Results: After 12 weeks of treatment, ZPG significantly reduced the mean [95% confidence interval] HAMD score vs. placebo (- 1.43 scores [- 2.50, - 0.36]; p = 0.009). The clinical remission rate and responders of the ZPG group were higher than those of the placebo (46.1% vs. 31.0%; p = 0.041; 34.8% vs. 18.4%; p = 0.014). A significant improvement in the PDSS-2 score was also observed in the ZPG group compared with that in the placebo group (- 3.56 scores [- 5.77, - 1.35]; p = 0.002). A total of 7 patients (7.1%) in the ZPG group had mild adverse events (AEs) vs 9 patients (9%) in the placebo group. No severe AEs were observed in either group. The randomization and controlled clinical study revealed that ZPG was effective, safe, and well-tolerated.Conclusion: ZPG combined with pramipexole further reduced the depressive symptoms and improved the sleeping quality of PD patients.

Objective: Health care expenditures for children with functional constipation (FC) are high, while conservative management is successful in only 50% of the children. The aim is to evaluate whether adding physiotherapy to conventional treatment (CT) is a cost-effective strategy in the management of children with FC aged 4-18 years in primary care.Methods: A cost-effectiveness analysis was performed alongside a randomized controlled trial (RCT) with 8-month follow-up. Costs were assessed from a societal perspective, effectiveness included both the primary outcome (treatment success defined as the absence of FC and no laxative use) and the secondary outcome (absence of FC irrespective of laxative use). Uncertainty was assessed by bootstrapping and cost-effectiveness acceptability curves (CEACs) were displayed.Results: One hundred and thirty-four children were randomized. The incremental cost-effectiveness ratio (ICER) for one additional successfully treated child in the physiotherapy group compared with the CT group was €24,060 (95% confidence interval [CI] €-16,275 to €31,390) and for the secondary outcome €1,221 (95% CI €-12,905 to €10,956). Subgroup analyses showed that for children with chronic laxative use the ICER was €2,134 (95% CI -24,975 to 17,192) and €571 (95% CI 11 to 3,566), respectively. At a value of €1,000, the CEAC showed a probability of 0.53 of cost-effectiveness for the primary outcome, and 0.90 for the secondary outcome.Conclusions: Physiotherapy added to CT as first-line treatment for all children with FC is not cost-effective compared with CT alone. Future studies should consider the cost-effectiveness of physiotherapy added to CT in children with chronic laxative use.Trial Registration: The RCT is registered in the Netherlands Trial Register (NTR4797), on the 8th of September 2014. The first child was enrolled on the 2nd of December 2014. https://www.trialregister.nl/trial/4654. [ABSTRACT FROM AUTHOR]

Background: Impaired cough results in airway secretion retention, atelectasis and pneumonia in individuals with Duchenne muscular dystrophy (DMD). Lung volume recruitment (LVR) stacks breaths to inflate the lungs to greater volumes than spontaneous effort. LVR is recommended in DMD clinical care guidelines but is not well studied. We aimed to determine whether twice-daily LVR, compared with standard of care alone, attenuates the decline in FVC at 2 years in boys with DMD.Methods: In this multicentre, assessor-blinded, randomised controlled trial, boys with DMD, aged 6-16 years with FVC >30% predicted, were randomised to receive conventional treatment or conventional treatment plus manual LVR twice daily for 2 years. The primary outcome was FVC % predicted at 2 years, adjusted for baseline FVC % predicted, age and ambulatory status. Secondary outcomes included change in chest wall distensibility (maximal insufflation capacity minus FVC) and peak cough flow.Results: Sixty-six boys (36 in LVR group, 30 in control) were evaluated (median age (IQR): 11.5 years (9.5-13.5), median baseline FVC (IQR): 85% predicted (73-96)). Adjusted mean difference in FVC between groups at 2 years was 1.9% predicted (95% CI -6.9% to 10.7%; p=0.68) in the direction of treatment benefit. We found no differences in secondary outcomes.Conclusion: There was no difference in decline in FVC % predicted with use of twice-daily LVR for boys with DMD and relatively normal lung function. The burden associated with routine LVR may outweigh the benefit. Benefits of LVR to maintain lung health in boys with worse baseline lung function still need to be clarified.Trial Registration Number: NCT01999075. [ABSTRACT FROM AUTHOR]

Background: Despite the potential for benefit, resilience remains an emergent area in late-life mental health care, and evidence of resilience intervention for suicide among nursing home residents is especially limited. This study aims to evaluate the effects of a resilience-targeted program based on the "I have, I am, and I can" strategy on suicidal ideation and related problems.Methods: From the 562 nursing home residents who were contacted, 68 with suicidal ideation were recruited and then randomly assigned to a resilience intervention group (eight-week resilience training; n = 34) or a wait-list control group (eight-week health education; n = 34). Self-reported suicidal ideation, and depression and anxiety symptoms as outcomes, and resilience as potential mediators were assessed at baseline, postintervention, and one-month follow-up.Results: Resilience training participants reported significant improvement in suicidal ideation (group × time interaction x2=12.564, p = 0.002) and depression symptoms (x2=9.441, p = 0.009) compared to wait-list control group participants. Changes in resilience mediated the intervention's effects on changes in suicidal ideation and depression symptoms. Limitations The observed effects must be considered preliminary due to the small sample size.Conclusions: The findings support the benefits of resilience training based on the "I have, I am, and I can" strategy in reducing suicidal ideation and suicide-related symptoms in nursing home older adults, and provide insight into possible mechanisms.

Study Question: Does processing of spermatozoa for IVF with ICSI by a microfluidic sperm separation device improve embryo quality compared with density-gradient centrifugation?Summary Answer: Patients randomized to microfluidic sperm preparation had similar cleavage- and blastocyst-stage embryo quality and clinical and ongoing pregnancy rates to those who underwent standard sperm processing for IVF with ICSI.What Is Known Already: Microfluidic sperm preparation can isolate spermatozoa for clinical use with minimal DNA fragmentation but with unclear impact on clinical outcomes.Study Design, Size, Duration: A prospective randomized controlled trial of 386 patients planning IVF from June 2017 through September 2021 was carried out.Participants/materials, Setting, Methods: One hundred and ninety-two patients were allocated to sperm processing with a microfluidic sperm separation device for ICSI, while 194 patients were allocated to clinical standard density-gradient centrifugation (control) at an academic medical centre.Main Results and the Role Of Chance: In an intention to treat analysis, there were no differences in high-quality cleavage-stage embryo fraction [66.0 (25.8)% control versus 68.0 (30.3) microfluidic sperm preparation, P = 0.541, absolute difference -2.0, 95% CI (-8.5, 4.5)], or high-quality blastocyst fraction [37.4 (25.4) control versus 37.4 (26.2) microfluidic sperm preparation, P = 0.985, absolute difference -0.6 95% CI (-6, 5.9)] between groups. There were no differences in the clinical pregnancy or ongoing pregnancy rates between groups.Limitations, Reasons For Caution: The population studied was inclusive and did not attempt to isolate male factor infertility cases or patients with a history of elevated sperm DNA fragmentation.Wider Implications Of the Findings: Microfluidic sperm separation performs similarly to density-gradient centrifugation in sperm preparation for IVF in an unselected population.Study Funding/competing Interest(s): No external funding to declare.

Background: The use of guideline-directed medical therapy (GDMT) is underprescribed in patients with heart failure with reduced ejection fraction (HFrEF).Objectives: This study sought to examine whether targeted and tailored electronic health record (EHR) alerts recommending GDMT in eligible patients with HFrEF improves GDMT use.Methods: PROMPT-HF (PRagmatic trial Of Messaging to Providers about Treatment of Heart Failure) was a pragmatic, EHR-based, cluster-randomized comparative effectiveness trial. A total of 100 providers caring for patients with HFrEF were randomized to either an alert or usual care. The alert notified providers of individualized GDMT recommendations along with patient characteristics. The primary outcome was an increase in the number of GDMT classes prescribed at 30 days postrandomization. Providers were surveyed on knowledge of guidelines and user experience.Results: The study enrolled 1,310 ambulatory patients with HFrEF from April to October 2021. Median age was 72 years; 31% were female; 18% were Black; and median left ventricular ejection fraction was 32%. At baseline, 84% of participants were receiving β-blockers, 71% received a renin-angiotensin-aldosterone system inhibitor, 29% received a mineralocorticoid receptor antagonist, and 11% received a sodium-glucose cotransporter-2 inhibitor. The primary outcome occurred in 176 of 685 (26%) participants in the alert arm vs 117 of 625 (19%) in the usual care arm, thus increasing GDMT class prescription by >40% after alert exposure (adjusted relative risk: 1.41; 95% CI: 1.03-1.93; P = 0.03). The number of patients needed to alert to result in an increase in addition of GDMT classes was 14. A total of 79% of alerted providers agreed that the alert was effective at enabling improved prescription of medical therapy for HF.Conclusions: A real-time, targeted, and tailored EHR-based alerting system for outpatients with HFrEF led to significantly higher rates of GDMT at 30 days when compared with usual care. This low-cost intervention can be rapidly integrated into clinical care and accelerate adoption of high-value therapies in heart failure.

Background: Plasmodium vivax forms dormant liver stages that can reactivate weeks or months following an acute infection. Recurrent infections are often associated with a febrile illness and can cause a cumulative risk of severe anaemia, direct and indirect mortality, and onward transmission of the parasite. There is an increased risk of P. vivax parasitaemia following falciparum malaria suggesting a rationale for universal use of radically curative treatment in patients with P. falciparum malaria even in the absence of detectable P. vivax parasitaemia in areas that are co-endemic for both species.Methods: This is a multicentre, health care facility-based, randomized, controlled, open-label trial in Bangladesh, Indonesia and Ethiopia. Patients with uncomplicated falciparum malaria, G6PD activity of ≥70% of the adjusted male median (AMM) and haemoglobin levels ≥8g/dl are recruited into the study and randomized to either receive standard schizonticidal treatment plus 7-day high dose primaquine (total dose 7mg/kg) or standard care in a 1:1 ratio. Patients are followed up weekly until day 63. The primary endpoint is the incidence risk of any P. vivax parasitemia on day 63. Secondary endpoints include incidence risk on day 63 of symptomatic P. vivax malaria and the risk of any P. falciparum parasitaemia. Secondary safety outcomes include the proportion of adverse events and serious adverse events, the incidence risk of severe anaemia (Hb<5g/dl and <7g/dl) and/or the risk for blood transfusion, the incidence risk of ≥ 25% fall in haemoglobin with and without haemoglobinuria, and the incidence risk of ≥ 25% fall in haemoglobin to under 7g/dl with and without haemoglobinuria.Discussion: This study evaluates the potential benefit of a universal radical cure for both P. vivax and P. falciparum in different endemic locations. If found safe and effective universal radical cure could represent a cost-effective approach to clear otherwise unrecognised P. vivax infections and hence accelerate P. vivax elimination.Trial Registration: NCT03916003 .

Background: Nowadays because of some necessities and demands for virtual and remote education, a new model of health approach through mobile-phones is widely used to deal with improving physical activity and its beneficial effect on pregnancy. There are a small number of studies for showing this importance and the efficacy of such methods, so this study was aimed to determine the influence of social networking through mobile phones on changing the physical activity behavior in pregnant women.Methods: This randomized controlled trial was conducted with parallel groups on 90 pregnant women referring to Urmia health centers in 2018-2019. The participants from various social and economic backgrounds were included. The participants were randomly assigned to a control and a treatment group. Demographic and Pregnancy Physical Activity Questionnaire (PPAQ) questionnaires were filled. In addition to routine cares, the treatment group received educational intervention through social network within 16 training sessions related to physical activity and nutrition in 8 weeks.Results: The mean weight in both control and treatment groups changed significantly during the study, but in different trends (P < 0.001, Mean Difference (MD) = 4.43). At the beginning of the study, control and treatment groups were not different in terms of daily physical activity level (P = 0.17, MD = 0.62), meanwhile, there was a statistically significant difference at the end of intervention in the level of daily physical activity (P < 0.001, MD = 0.69). Comparison of both groups, based on different categories of activity level at the end of the treatment, showed a non-significant difference in sedentary activities (P = 0.89, MD = 0.46), but the intervention led to a significant difference based on the other level of activities; light (P < 0.001, MD = 51.94), moderate (P < 0.001, MD = 46.87), and sever (P = 0.05, MD = 1.07).Conclusion: Educational intervention based on social networks through mobile phones had an effective role in behavior change in physical activity during pregnancy.Trial Registration: IRCT20151004024340N15, Registration date05/06/2020.

Background: Menaquinone-7 (MK-7), also known as vitamin K2, is a cofactor for the carboxylation of proteins involved in the inhibition of arterial calcification and has been suggested to reduce the progression rate of aortic valve calcification (AVC) in patients with aortic stenosis.Methods: In a randomized, double-blind, multicenter trial, men from the community with an AVC score >300 arbitrary units (AU) on cardiac noncontrast computer tomography were randomized to daily treatment with tablet 720 µg MK-7 plus 25 µg vitamin D or matching placebo for 24 months. The primary outcome was the change in AVC score. Selected secondary outcomes included change in aortic valve area and peak aortic jet velocity on echocardiography, heart valve surgery, change in aortic and coronary artery calcification, and change in dp-ucMGP (dephosphorylated-undercarboxylated matrix Gla-protein). Safety outcomes included all-cause death and cardiovascular events.Results: From February 1, 2018, to March 21, 2019, 365 men were randomized. Mean age was 71.0 (±4.4) years. The mean (95% CI) increase in AVC score was 275 AU (95% CI, 225-326 AU) and 292 AU (95% CI, 246-338 AU) in the intervention and placebo groups, respectively. The mean difference on AVC progression was 17 AU (95% CI, -86 to 53 AU; P=0.64). The mean change in aortic valve area was 0.02 cm2 (95% CI, -0.09 to 0.12 cm2; P=0.78) and in peak aortic jet velocity was 0.04 m/s (95% CI, -0.11 to 0.02 m/s; P=0.21). The progression in aortic and coronary artery calcification score was not significantly different between patients treated with MK-7 plus vitamin D and patients receiving placebo. There was no difference in the rate of heart valve surgery (1 versus 2 patients; P=0.99), all-cause death (1 versus 4 patients; P=0.37), or cardiovascular events (10 versus 10 patients; P=0.99). Compared with patients in the placebo arm, a significant reduction in dp-ucMGP was observed with MK-7 plus vitamin D (-212 pmol/L versus 45 pmol/L; P<0.001).Conclusions: In elderly men with an AVC score >300 AU, 2 years MK-7 plus vitamin D supplementation did not influence AVC progression.Registration: URL: https://www.Clinicaltrials: gov; Unique identifier: NCT03243890.

Background: OSA is associated with metabolic syndrome (MS), but it is unclear whether OSA treatment with CPAP can revert MS.Research Question: Does OSA treatment with CPAP per se have effects on the MS reversibility and the associated metabolic, adiposity and vascular parameters?Study Design and Methods: The TREATOSA-MS trial is a randomized placebo-controlled trial that enrolled adult patients with a recent diagnosis of MS and moderate or severe OSA (apnea-hypopnea index [AHI], ≥ 15 events/h) to undergo therapeutic CPAP or nasal dilator strips (placebo group) for 6 months. Before and after each intervention, we measured anthropometric variables, BP, glucose, and lipid profile. To control potential-related mechanisms and consequences, we also measured adiposity biomarkers (leptin and adiponectin), body composition, food intake, physical activity, subcutaneous and abdominal fat (visceral and hepatic fat), and endothelial function.Results: One hundred patients (79% men; mean age, 48 ± 9 years; BMI, 33 ± 4 kg/m2; AHI, 58 ± 29 events/h) completed the study (n = 50 per group). The mean CPAP adherence was 5.5 ± 1.5 h/night. After 6 months, most patients with OSA randomized to CPAP retained the MS diagnosis, but the rate of MS reversibility was higher than observed in the placebo group (18% vs 4%; OR, 5.27; 95% CI, 1.27-35.86; P = .04). In the secondary analysis, CPAP did not promote significant reductions in the individual components of MS, weight, hepatic steatosis, lipid profile, adiponectin, and leptin, but did promote a very modest reduction in visceral fat and improved endothelial function (all analyses were adjusted for baseline values).Interpretation: Despite the higher rate of MS reversibility after CPAP therapy as compared with placebo, most patients retained this diagnosis. The lack of significant or relevant effects on adiposity biomarkers and depots supports the modest role of OSA in modulating MS.Trial Registration: ClinicalTrials.gov; No.: NCT02295202; URL: www.Clinicaltrials: gov.

Rationale: Pleural effusion commonly complicates community-acquired pneumonia and is associated with intense pleural inflammation. Whether antiinflammatory treatment with corticosteroids improves outcomes is unknown. Objectives: To assess the effects of corticosteroids in an adult population with pneumonia-related pleural effusion. Methods: The STOPPE (Steroid Therapy and Outcome of Parapneumonic Pleural Effusions) trial was a pilot, multicenter, double-blinded, placebo-controlled, randomized trial involving six Australian centers. Patients with community-acquired pneumonia and pleural effusion were randomized (2:1) to intravenous dexamethasone (4 mg twice daily for 48 h) or placebo and followed for 30 days. Given the diverse effects of corticosteroids, a comprehensive range of clinical, serological, and imaging outcomes were assessed in this pilot trial (ACTRN12618000947202). Measurements and Main Results: Eighty patients were randomized (one withdrawn before treatment) and received dexamethasone (n = 51) or placebo (n = 28). This pilot trial found no preliminary evidence of benefits of dexamethasone in improving time to sustained (>12 h) normalization of vital signs (temperature, oxygen saturations, blood pressure, heart, and respiratory rates): median, 41.0 (95% confidence interval, 32.3-54.5) versus 27.8 (15.4-49.5) hours in the placebo arm (hazard ratio, 0.729 [95% confidence interval, 0.453-1.173]; P = 0.193). Similarly, no differences in C-reactive protein or leukocyte counts were observed, except for a higher leukocyte count in the dexamethasone group at Day 3. Pleural drainage procedures were performed in 49.0% of dexamethasone-treated and 42.9% of placebo-treated patients (P = 0.60). Radiographic pleural opacification decreased over time with no consistent intergroup differences. Mean duration of antibiotic therapy (22.4 [SD, 15.4] vs. 20.4 [SD, 13.8] d) and median hospitalization (6.0 [interquartile range, 5.0-10.0] vs. 5.5 [interquartile range, 5.0-8.0] d) were similar between the dexamethasone and placebo groups. Serious adverse events occurred in 25.5% of dexamethasone-treated and 21.4% of placebo-treated patients. Transient hyperglycemia more commonly affected the dexamethasone group (15.6% vs. 7.1%). Conclusions: Systemic corticosteroids showed no preliminary benefits in adults with parapneumonic effusions. Clinical trial registered with www.anzctr.org.au (ACTRN12618000947202).

Background: This study aimed to explore the efficacy of Nd:YAG laser-assisted periodontal therapy for management of patients with stage II-IV periodontitis.Methods: Patients who presented with residual periodontal pockets were enrolled. After non-surgical periodontal therapy (NSPT), test sites received Nd:YAG laser (first entrance to pocket: 3 W, 100 μs, 20 Hz; second entrance: 4 W, 600 μs, 20 Hz) and control sites received placebo (laser off). Periodontal probing depth (PPD), clinical attachment level (CAL), gingival recession (GR), bleeding on probing (BOP), and plaque index (PI) were recorded at baseline and 1, 2, 3, 4 and 6-month visits.Results: Twenty patients completed the 6-month period. Significant reductions in PPD, CAL, BOP, and PI values and a significant increase in GR at all follow-up visits compared to the baseline (all P < 0.001) were revealed in both groups. Test sites showed significantly greater improvement in PPD (P = 0.0002) and greater increase in GR (P < 0.0001) compared to the control sites at 6-month visit. There was no difference between two groups regarding CAL gain through the study period (P = 0.23).Conclusion: NSPT+Nd:YAG laser with the current protocol results in greater PPD reduction compared to NSPT alone. However, this reduction is likely because of greater GR rather than attachment gain. Therefore, the adjunction of Nd:YAG laser (with the current setting) to the NSPT for the treatment of residual periodontal pockets did not ameliorate the clinical outcomes (ClinicalTrials.gov ID: NCT03365167).

Purpose: Comparison of three ultrasound (US) frequencies for phacoemulsification of hard cataracts to determine a frequency that makes phacoemulsification more efficacious and safer.Methods: A randomized controlled trial was undertaken at a medical college and hospital. In total, 207 patients with grade 5.6-6.9 (LOCS III) senile cataract were randomized into three groups. Group I underwent phacoemulsification with 28-kHz frequency, group II with 42-kHz frequency, and group III with 53-kHz frequency. The effective phacoemulsification time (EPT) and estimated fluid usage (EFU) were compared intraoperatively. The endothelial cell parameters were analyzed for 6 months.Results: The groups were matched for age (P = 0.467), gender (P = 0.497), nuclear grade (P = 0.321), and anterior chamber depth (P = 0.635). The EPT and EFU were significantly lower in group III, compared to group II and group I, with P < 0.0001 and P < 0.0001, respectively. Postoperatively, the endothelial cell density (ECD) was significantly higher in group III at 1 month (P < 0.0001), 3 months (P < 0.0001), and 6 months (P < 0.0001). The percentages of ECD loss were also significantly lower in group III; the difference was statistically significant (P < 0.0001) up to 6 months postoperatively.Conclusion: Higher frequency ultrasound was associated with a lower EPT and EFU as well as better endothelial preservation than lower frequencies in hard cataracts.

Background: This randomized, controlled clinical trial aimed to compare the differences in periodontal clinical outcomes, duration of the procedure, and patient's experience between conventional scaling and root planing and erbium-doped: yttrium-aluminum-garnet (Er:YAG) in the treatment of generalized moderate to severe chronic periodontitis or generalized Stages II or III, and Grade B periodontitis based on the Centers for Disease Control (CDC), American Academy of Periodontology (AAP), and European Federation of Periodontology (EFP) definitions.Methods: Thirty subjects were initially recruited. In a split-mouth fashion, right and left sides were randomly allocated into two treatment arms: conventional scaling and root planing (C-SRP) versus laser-assisted scaling and root planing (L-SRP). A blinded examiner recorded clinical measurements at baseline and 3 months. Duration of the procedure was also recorded for each visit, and the patient's experience was assessed with a questionnaire at baseline, 1, and 3 months.Results: The final sample consisted of 26 subjects. Both treatments resulted in overall improvement, but no significant differences were found between modalities for clinical attachment gain or probing depth reduction. The duration of the procedure was approximately half for L-SRP, and postoperative sensitivity was greater in C-SRP.Conclusions: The low-energy protocol with Er:YAG (50 mJ) used for the non-surgical treatment of moderate-severe chronic or Stage II-III, Grade B periodontitis performed in this study population was a treatment modality that yielded similar clinical improvements when compared to conventional scaling and root planing.

Background: To investigate the analgesic effect of perioperative use of duloxetine in patients received total knee arthroplasty (TKA).Method: This prospective randomized, double-blind, placebo-controlled trial study was registered in the Chinese Clinical Trial Registry (ChiCTR2000033910). 100 patients were finally enrolled. The hospital pharmacy prepared small capsules containing either duloxetine or starch (placebo) which were all identical in appearance and weight (50:50). The 100 enrolled patients were given a capsule (containing either 60 mg duloxetine or 60 mg placebo) every night before sleep since preoperative day 2 till postoperative day 14 (17 days in all) by a nurse who were not involved in this trial. Other perioperative managements were the same in the two groups. The primary outcome was the VAS score, including rVAS (visual analogue scale at rest) and aVAS (visual analogue scale upon ambulation) throughout the perioperative period. The secondary outcomes included opioid consumption, range of motion, including both active range of motion (aROM) and passive range of motion (pROM) and adverse events. The patients were followed up everyday until 7 days after TKA, afterwards, they were followed up at the time of 3 weeks and 3 months after TKA.Result: rVAS in duloxetine group were significantly less than placebo group throughout the postoperative period: 4.7 ± 2.3 vs 5.9 ± 2.6 (P = 0.016) at 24 h postoperative; 2.1 ± 1.6 vs 2.8 ± 1.7 (P = 0.037) at 7 days postoperative. In terms of aVAS, similarly, duloxetine group had less aVAS than placebo group throughout the postoperative period: 6.2 ± 2.1 vs 7.1 ± 2.2 (P = 0.039) at 24 h postoperative; 3.3 ± 1.7 vs 4.1 ± 2.0 (P = 0.034) at 7 days postoperative. Patients in duloxetine group consumed significantly less opioids per day than the placebo group: 24.2 ± 10.1 g vs 28.5 ± 8.3 g (P = 0.022) at 24 h postoperative; 2.7 ± 2.5 g vs 4.1 ± 2.6 g (P = 0.007) at 7 days postoperative. aROM in duloxetine group were significantly better than placebo group until postoperative day 6, the aROM became comparable between the two groups: 110.2 ± 9.9° in duloxetine group vs 107.5 ± 11.5° in control group (P = 0.211). In terms of pROM, duloxetine group had significantly better pROM until postoperative day 5, the pROM became comparable between the two groups: 103.8 ± 12.1° in duloxetine group vs 99.5 ± 10.8° in control group (P = 0.064). No significant difference was found between the two groups in the rates of dizziness, bleeding, sweating, fatigue and dryness of mouth. In the placebo group, more patients got nausea/vomiting and constipation (P < 0.05). However, in terms of drowsiness, duloxetine group was reported higher rate (P < 0.05).Conclusion: Several other RCTs have already mentioned the analgesic effect of duloxetine, but not in the immediate postoperative period. In this study, we found duloxetine could reduce acute postoperative pain in the immediate postoperative period and decrease the opioids consumption as well as accelerating postoperative recovery, without increasing the risk of adverse medication effects in patients undergoing TKA. Duloxetine could act as a good supplement in multimodal pain management protocol for patients undergoing TKA.Trial Registration Statement: This study was registered in the Chinese Clinical Trial Registry (ChiCTR2000033910).

Background: Direct oral anticoagulants (DOACs) are an alternative to low-molecular-weight heparin for treating cancer-associated VTE.Research Question: Is rivaroxaban as efficient and safe as dalteparin to treat patients with cancer-associated VTE?Study Design and Methods: In a randomized open-label noninferiority trial, patients with active cancer who had proximal DVT, pulmonary embolism (PE), or both were assigned randomly to therapeutic doses of rivaroxaban or dalteparin for 3 months. The primary outcome was the cumulative incidence of recurrent VTE, a composite of symptomatic or incidental DVT or PE, and worsening of pulmonary vascular or venous obstruction at 3 months.Results: Of 158 randomized patients, 74 and 84 patients were assigned to receive rivaroxaban and dalteparin, respectively. Mean age was 69.4 years, and 115 patients (76.2%) had metastatic disease. The primary outcome occurred in 4 and 6 patients in the rivaroxaban and dalteparin groups, respectively (both the intention-to-treat and per-protocol populations: cumulative incidence, 6.4% vs 10.1%; subdistribution hazard ratio [SHR], 0.75; 95% CI, 0.21-2.66). Major bleeding occurred in 1 and 3 patients in the rivaroxaban and dalteparin groups, respectively (cumulative incidence, 1.4% vs 3.7%; SHR, 0.36; 95% CI, 0.04-3.43). Major or clinically relevant nonmajor bleeding occurred in 9 and 8 patients in the rivaroxaban and dalteparin groups, respectively (cumulative incidence, 12.2% vs 9.8%; SHR, 1.27; 95% CI, 0.49-3.26). Overall, 19 patients (25.7%) and 20 patients (23.8%) died in the rivaroxaban and dalteparin groups, respectively (hazard ratio, 1.05; 95% CI, 0.56-1.97).Interpretation: In this trial comparing rivaroxaban and dalteparin in the treatment of cancer-associated VTE, the number of patients was insufficient to reach the predefined criteria for noninferiority, but efficacy and safety results were consistent with those previously reported with DOACs. An updated meta-analysis of randomized trials comparing DOACs with low-molecular-weight heparin in patients with cancer-associated VTE is provided.Trial Registry: ClinicalTrials.gov; No.: NCT02746185; URL: www.Clinicaltrials: gov.

Purpose: Physicians' use of self-assessment to guide quality improvement or board certification activities often does not correlate with more objective measures, and they may spend valuable time on activities that support their strengths instead of addressing gaps. Our objective was to study whether viewing quality measures, with peer comparisons, would affect the selection of certification activities.Methods: We conducted a cluster-randomized controlled trial-the Trial of Data Exchange for Maintenance of certification and Raising Quality (TRADEMaRQ)-with 4 partner organizations during 2015-2017. Physicians were presented their quality data within their online certification portfolios before (intervention) vs after (control) they chose board certification activities. The primary outcome was whether the selected activity addressed a quality gap (a quality area in which the physician scored below the mean for the study population).Results: Of 2,570 invited physicians, 254 physicians completed the study: 130 in the intervention group and 124 in the control group. Nearly one-fifth of participating physicians did not complete any certification activities during the study. A sizable minority of those in the intervention group, 18.4%, never reviewed their quality dashboard. Overall, just 27.2% of completed certification activities addressed a quality gap, and there was no significant difference in this outcome in the intervention group vs the control group in either bivariate or adjusted analyses (odds ratio = 1.28; 95% CI, 0.90-1.82).Conclusions: Physicians did not use quality performance data in choosing certification activities. Certification boards are being pressed to make their programs relevant to practice, less burdensome, and supportive of quality improvement in alignment with value-based payment models. Using practice data to drive certification choices would meet these goals. [ABSTRACT FROM AUTHOR]

Intravenous immunoglobulin treatment for chronic inflammatory demyelinating polyneuropathy usually starts with a 2.0 g/kg induction dose followed by 1.0 g/kg maintenance doses every 3 weeks. No dose-ranging studies with intravenous immunoglobulin maintenance therapy have been published. The Progress in Chronic Inflammatory Demyelinating polyneuropathy (ProCID) study was a prospective, double-blind, randomized, parallel-group, multicentre, phase III study investigating the efficacy and safety of 10% liquid intravenous immunoglobulin (Panzyga®) in patients with active chronic inflammatory demyelinating polyneuropathy. Patients were randomized 1:2:1 to receive the standard intravenous immunoglobulin induction dose and then either 0.5, 1.0 or 2.0 g/kg maintenance doses every 3 weeks. The primary end point was the response rate in the 1.0 g/kg group, defined as an improvement ≥1 point in adjusted Inflammatory Neuropathy Cause and Treatment score at Week 6 versus baseline and maintained at Week 24. Secondary end points included dose response and safety. This trial was registered with EudraCT (Number 2015-005443-14) and clinicaltrials.gov (NCT02638207). Between August 2017 and September 2019, the study enrolled 142 patients. All 142 were included in the safety analyses. As no post-infusion data were available for three patients, 139 were included in the efficacy analyses, of whom 121 were previously on corticosteroids. The response rate was 80% (55/69 patients) [95% confidence interval (CI): 69-88%] in the 1.0 g/kg group, 65% (22/34; CI: 48-79%) in the 0.5 g/kg group, and 92% (33/36; CI: 78-97%) in the 2.0 g/kg group. While the proportion of responders was higher with higher maintenance doses, logistic regression analysis showed that the effect on response rate was driven by a significant difference between the 0.5 and 2.0 g/kg groups, whereas the response rates in the 0.5 and 2.0 g/kg groups did not differ significantly from the 1.0 g/kg group. Fifty-six per cent of all patients had an adjusted Inflammatory Neuropathy Cause and Treatment score improvement 3 weeks after the induction dose alone. Treatment-related adverse events were reported in 16 (45.7%), 32 (46.4%) and 20 (52.6%) patients in the 0.5, 1.0 and 2.0 g/kg dose groups, respectively. The most common adverse reaction was headache. There were no treatment-related deaths. Intravenous immunoglobulin (1.0 g/kg) was efficacious and well tolerated as maintenance treatment for patients with chronic inflammatory demyelinating polyneuropathy. Further studies of different maintenance doses of intravenous immunoglobulin in chronic inflammatory demyelinating polyneuropathy are warranted. [ABSTRACT FROM AUTHOR]

Background and Objectives: Inflammatory cytokines and metabolic abnormalities are common in patients with tuberculosis. Observational studies have indicated that probiotics modulate inflammatory cytokines and metabolites; however, clinical evidence of the effect of probiotics on patients with tuberculosis is lacking. This study investigated the effects of Lactobacillus casei on inflammatory cytokines and metabolites during tuberculosis treatment.Methods and Study Design: A randomized controlled trial was conducted. A total of 47 inpatients were included and randomly assigned to receive standard antituberculosis therapy only (control group) or that treatment together with 1 × 1010 colony-forming units per day of Lactobacillus casei (low-dose group) or 2 × 1010 colony-forming units per day of Lactobacillus casei (high-dose group) for 4 weeks of intensive treatment during hospitalization. Plasma samples were analyzed for inflammatory cytokines and metabolomics with ELISA kits and ultrahigh performance liquid chromatography quadrupole time-of-flight mass spectrometry.Results: Daily Lactobacillus casei supplementation of up to 2 × 1010 colony-forming units significantly lowered the concentrations of tumor necrosis factor-α, interleukin-6, interleukin-10, and interleukin-12 (p=0.007, p=0.042, p=0.002, p<0.001, respectively) in patients with tuberculosis. Compared with the control and low-dose groups, the plasma metabolites of phosphatidylserine, maresin 1, phosphatidylcholine, L-saccharopine, and pyridoxamine were significantly upregulated, and N-acetylmethionine, L-tryptophan, phosphatidylethanolamine, and phenylalanine were downregulated in the high-dose group. Strong correlations were observed between metabolites and inflammatory cytokines.Conclusions: Lactobacillus casei supplementation during the intensive phase of tuberculosis treatment can significantly modulate inflammatory cytokines and metabolites. Decreased inflammatory cytokines may be related to metabolite changes. [ABSTRACT FROM AUTHOR]

Objective: Investigate whether resuming physical activity (PA) at 72 hours post concussion is safe and reduces symptoms at 2 weeks, compared with resting until asymptomatic.Methods: Real-life conditions, multicentre, single-blinded randomised clinical trial, conducted in three Canadian paediatric emergency departments (ED). Children/youth aged 10-<18 years with acute concussion were recruited between March 2017 and December 2019, and randomly assigned to a 4-week stepwise return-to-PA protocol at 72 hours post concussion even if symptomatic (experimental group (EG)) or to a return-to-PA once asymptomatic protocol (control group (CG)). The primary outcome was self-reported symptoms at 2 weeks using the Health and Behaviour Inventory. Adherence was measured using accelerometers worn 24 hours/day for 14 days post injury. Adverse events (AE) (worsening of symptoms requiring unscheduled ED or primary care visit) were monitored. Multivariable intention-to-treat (ITT) and per-protocol analyses adjusting for prognostically important covariates were examined. Missing data were imputed for the ITT analysis.Results: 456 randomised participants (EG: N=227; mean (SD) age=13.3 (2.1) years; 44.5% women; CG: N=229; mean (SD) age=13.3 (2.2) years; 43.7% women) were analysed. No AE were identified. ITT analysis showed no strong evidence of a group difference at 2 weeks (adjusted mean difference=-1.3 (95% CI:-3.6 to 1.1)). In adherent participants, initiating PA 72 hours post injury significantly reduced symptoms 2 weeks post injury, compared with rest (adjusted mean difference=-4.3 (95% CI:-8.4 to -0.2)).Conclusion: Symptoms at 2 weeks did not differ significantly between children/youth randomised to initiate PA 72 hours post injury versus resting until asymptomatic; however, many were non-adherent to the intervention. Among adherent participants, early PA was associated with reduced symptoms at 2 weeks. Resumption of PA is safe and may be associated with milder symptoms at 2 weeks.Level Of Evidence: 1b.Trial Registration Number: NCT02893969.Registry Name: Pediatric Concussion Assessment of Rest and Exertion (PedCARE).

Background: Long-term exposure to high concentrations of PM2.5 may cause immune system dysfunction and damage to the respiratory and cardiovascular systems. PM2.5 may cause CD4 + T helper cells to polarize toward TH1 or TH2 cell types, which may be associated with the onset and progression of many human diseases. Recent studies have shown that omega-3 fatty acids can regulate human immune function and reduce physiological damage caused by air pollution; however, only limited research has examined the therapeutic effects of omega-3 fatty acids on subjects with high exposure to PM2.5 in mass transit systems such as subways.Methods: This study was designed as a prospective, randomized, double-blinded (to participants and researchers), placebo-controlled clinical trial. The research plan is to randomly select 120 eligible adults based on the difference in PM2.5 exposure in the Chengdu subway station. They should be aged 20-65 years old and work in the subway station more than or equal to 3 times a week, each time greater than or equal to 8 h, and had worked continuously in the subway station for more than 2 years. All participants will receive omega-3 fatty acids or placebo for 8 weeks. The primary outcomes will be changes in the TH1/TH2 cell polarization index and changes in serum cytokine concentrations. Secondary outcomes will be changes in early indicators of atherosclerosis, pulmonary function, COOP/WONCA charts, and scores on the Short-Form 36 Health Survey for quality of life. Results will be analyzed to evaluate differences in clinical efficacy between the two groups. A 6-month follow-up period will be used to assess the long-term value of omega-3 fatty acids for respiratory and cardiovascular disease endpoints.Discussion: We will explore the characteristics of the TH1/TH2 cell polarization index in a population with high exposure to PM2.5. Omega-3 fatty acids and placebo will be compared in many ways to test the effect on people exposed to PM2.5 subway stations. This study is expected to provide reliable evidence to support the promotion of omega-3 fatty acids in clinical practice to protect individuals who are highly exposed to PM2.5.Trial Registration: Chinese Clinical Trial Registry ChiCTR2000038065 .

Background: Although transition programs have been evaluated for adolescents with chronic conditions, these have rarely involved process evaluations. Indeed, outcomes of complex interventions are dependent on how the intervention is implemented in practice and evaluations of implementation process are therefore pivotal. The aim of this study was to evaluate the extent to which a transition program for adolescents with congenital heart disease was delivered as intended. Research questions were 1) to what level of fidelity was the program delivered? and 2) what potential moderating factors affected the delivery of the program and overall fidelity?Methods: A mixed methods design was used, where a process evaluation was embedded in the STEPSTONES randomized controlled trial in Sweden. The implementation fidelity framework by Carrol (2007) and Hasson (2010) was used to design, collect and analyze data. Quantitative data consisted of intervention records on adherence and were analyzed with descriptive statistics. Qualitative data on moderators affecting fidelity were collected through interviews, log-books and focus group interviews with healthcare professionals implementing the intervention and participatory observations of the implementation process. Data were analyzed with deductive content analysis. Triangulation was used to integrate quantitative and qualitative data within the fidelity framework.Results: Six out of eight components of the transition program were delivered to an extent that adhered to the program theory or achieved a high level of fidelity. However, components involving peer support had a low attendance by the participating sample (32.2%), and the joint transfer meeting was challenging to implement, despite achieving high adherence. Moderators affecting the implementation process were the adolescent's and healthcare professional's engagement in the intervention, contextual factors and a lack of standard operating procedures for all components in the program.Conclusion: Barriers and facilitators for a future implementation of transition programs have been illuminated in this study. The use of an implementation fidelity framework in the process evaluation proved successful in providing a comprehensive evaluation of factors affecting the implementation process. However, implementation fidelity must be considered in relation to adaptations to the local and personal prerequisites in order to create interventions that can achieve fit. [ABSTRACT FROM AUTHOR]

Background: Nonalcoholic fatty liver disease (NAFLD) is frequent among patients undergoing bariatric surgery. Beyond weight reduction, dietary supplements like micronutrients or probiotics that modify insulin resistance and lipotoxicity can be used to prevent or delay the progression of liver disease.Objectives: We evaluated the effect of a dietary approach with a specifically tailored multistrain probiotic and micronutrient mixture compared with a basic care micronutrient supplement on serum alanine aminotransferase (ALAT) in obese patients after mini gastric bypass (MGB) surgery.Methods: This randomized, double-blind, controlled trial included 60 obese patients (age: 40 ± 10 y; BMI: 44 ± 3 kg/m²). Patients received a combination of specifically tailored multistrain probiotic powder and a specific micronutrient mixture (Pro+SM) or a control treatment consisting of a placebo and a basic care micronutrient mixture (Con+BM), with some micronutrients in lower doses than SM, for 12 wk after hospital discharge. Primary (serum ALAT) and secondary outcomes [serum aspartate aminotransferase (ASAT), fatty liver index, NAFLD fibrosis score, glucose metabolism, blood pressure (BP), heart rate] were assessed at week 0 and week 12. Data were analyzed using unpaired Student's t-tests or Mann-Whitney U tests to compare the changes due to each treatment to one another.Results: A total of 48 patients were included in the analyses. Changes in serum ALAT concentrations did not differ between groups. Compared with Con+BM, Pro+SM improved serum ASAT (difference: -8.0 U/L, 95% CI: -17.0, -4.0; P = 0.043), NAFLD fibrosis score (difference: -0.39; 95% CI: -0.78, 0; P = 0.048), serum triglycerides (difference: -22.8 mg/dL; 95% CI: -45.6, -0.1; P = 0.049) and the visceral adiposity index (difference: -0.70; 95% CI: -1.31, -0.08; P = 0.027).Conclusion: Supplementation with a specifically tailored probiotic and micronutrient mixture improved NAFLD-related markers more than a basic micronutrient mixture in obese patients following MGB surgery. The trial was registered under clinicaltrials.gov as NCT03585413. [ABSTRACT FROM AUTHOR]

Abstract: Neuro-orthopedic disorders are common in patients with disorders of consciousness (DOC) and can lead to potential pain. However, the patients' inability to communicate makes pain detection and management very challenging for clinicians. In this crossover randomized double-blind placebo-controlled study, we investigated the effects of an analgesic treatment on the presence of nociception-related behaviors. At baseline, the Nociception Coma Scale-Revised (NCS-R) was performed in 3 conditions: a non-noxious stimulation, a noxious stimulation, and during a physiotherapy session. Patients with a NCS-R total score during physiotherapy equal or above the score observed after the noxious stimulation could participate to the clinical trial, as well as patients with a score above 5. They received an analgesic treatment and a placebo on 2 consecutive days in a randomized order followed by an assessment with the NCS-R. Of the 18 patients, 15 displayed signs of potential pain during physiotherapy. Patients showed higher NCS-R scores during physiotherapy compared with the other conditions, suggesting that mobilizations were potentially painful. Of these 15 patients, 10 met the criteria to participate in the placebo-controlled trial. We did not find any effect of analgesic treatment on the NCS-R scores. This study highlights that physiotherapy may be potentially painful for patients with DOC, while analgesic treatments did not reduced NCS-R scores. Therefore, careful monitoring with appropriate assessment and treatment before and during mobilization should become a priority in clinical settings. Future studies should focus on the development of assessment tools sensitive to analgesic dosage to manage pain in DOC. [ABSTRACT FROM AUTHOR]

Recovery-oriented practice has been advocated in mental health services in Hong Kong since 2009. Well-being has become an important area of focus for mental health services. Positive Psychotherapy for Psychosis (PPP) is a well-being-focused intervention for use in psychosis, with preliminary evidence from a randomized controlled trial in the United Kingdom of impact on well-being and symptomatology. The aim of this study was to test the effectiveness of PPP on the well-being of people with psychosis in Hong Kong. The study was a randomized controlled trial with two-arm parallel groups. Both groups received treatments as usual, and in addition the intervention group received a 13-session intervention based on a Cantonese Chinese translation of the PPP manual. Intention-to-treat analysis was used. The trial was registered (ANZCTR: ACTRN12620000464965). A total of 154 participants (78 intervention, 76 control) were recruited. As compared to control group, intervention group participants showed significant changes over time on the primary outcome of well-being assessed using the Chinese Short Warwick-Edinburgh Mental Well-being Scale (p = 0.001) and on secondary outcomes of hope (Agency subscale: p = 0.029) and self-efficacy (p = 0.001). Positive Psychotherapy for Psychosis was found to be an effective treatment in improving the well-being and other mental health outcomes for people with psychosis. It can be recommended for use in mental health services to promote recovery. [ABSTRACT FROM AUTHOR]

Study Design: Randomized controlled trial.Objective: To evaluate the efficacy of adjunctive topical tranexamic acid (tTXA) in reducing postoperative blood loss and packed red cell (PRC) transfusion in patients who underwent palliative decompressive spinal metastasis surgery for malignant epidural spinal cord compression.Summary Of Background Data: Palliative decompressive spinal metastasis surgery is associated with massive postoperative blood loss and increased transfusion rate. tTXA reduces blood loss in traumatic or degenerative spinal surgery; however, the role of topical TXA in decompressive spinal metastasis surgery remains controversial.Method: A total of 65 patients who underwent palliative decompressive thoracolumbar spinal metastasis surgery were included in this study. In 33 patients, 1 g of tTXA (20 mL) was soaked in an absorbable gelatin sponge and placed lateral to the decompressive site. The remaining 32 patients in the control group received the same procedures with normal saline at the same volume, instead of TXA. All of the patients received standard 1 g intravenous TXA, just before initiating the operation. The primary outcome was postoperative blood loss, and the secondary outcomes were postoperative PRC transfusion and complications.Results: No differences were found in postoperative blood loss between tTXA and placebo group (P50 778 mL [IQR 347, 1,122 mL] versus P50 490 mL [IQR 295, 920 mL]; P = 0.238). The number of patients requiring postoperative PRC transfusion were quite similar in tTXA and placebo groups (PRC transfusion in 15 patients [45.45%] versus 16 patients [50%]; P = 0.585). No complications related to TXA and absorbable gelatin sponge were observed.Conclusion: We do not recommend tTXA as an adjunctive treatment for patients undergoing decompressive spinal metastasis surgery since it does not provide additional benefit to prophylactic intravenous TXA in postoperative blood loss and transfusion rate.Level of Evidence: 2.

Objectives: Use of Motivational Interviewing (MI) in education may improve medication-overuse headache (MOH) patients' ability to cope with pain. In a randomised controlled trial, we evaluated the effect of education focusing on behavioural change among MOH patients.Methods: Ninety-eight MOH patients were randomized (1:1) to standard treatment and 12-weeks of MI-based education versus standard treatment alone after detoxification. Outcome of interest was changes in coping strategies measured by the Coping Strategy Questionnaire at four- and nine months.Results: The educational program improved patients' perceived efficacy in the use of their coping strategies to control pain, both at four-and nine months follow-up (mean±SE): ∆:0.84 ± 0.35, 95% CI:0.16;1.52, p = 0.02 and: ∆: 0.90 ± 0.39, 95% CI:0.14;1.66, p = 0.02, respectively. No between-group differences were detected in the other coping subscales. Within the intervention group, the coping strategy subscales Catastrophizing, and Reinterpretation of pain sensation were significantly improved at nine months follow-up (p = 0.003 vs. p = 0.012, respectively). No changes were found in the control group.Conclusion: MI-based education focused on behavioural changes improved MOH patients' perceived efficacy in the use of their coping strategies to control pain.Practice Implications: Education based on MI could be valuable for MOH patients with respect to behavioural changes and perceived headache control.

Study Question: Does in vitro maturation (IVM) result in non-inferior cumulative live birth rates compared to those after standard in vitro fertilization (IVF) in infertile women with polycystic ovary syndrome (PCOS)?Summary Answer: One cycle of IVM, without any stimulation, was inferior to one cycle of standard IVF in women with PCOS in terms of 6-month cumulative live birth rates, when choosing single vitrified-warmed blastocyst transfer.What Is Known Already: IVM is an emerging alternative treatment for women with PCOS who need assisted reproductive technology. Since a minimal or even zero dose of gonadotropins are required in the IVM procedure, the occurrence of ovarian hyperstimulation syndrome (OHSS) is eliminated. Only one clinical trial comparing the pregnancy outcome between IVM with FSH priming and IVF has been reported. However, it is still unknown whether IVM treatment without any stimulation can offer a similar live birth outcome in women with PCOS as compared to that in women receiving the standard IVF procedure with ovarian stimulation.Study Design, Size, Duration: This single-centre, open-label randomized controlled non-inferiority trial in an academic infertility centre in China was performed between March 2018 and July 2019.Participants/materials, Setting, Methods: Women aged 20-38 years with PCOS and infertility scheduled for their first IVF attempt were eligible. In total, 351 women were randomly allocated to receive one cycle of unstimulated IVM (n = 175) or one cycle of standard IVF with a flexible GnRH antagonist protocol and hCG as ovulatory trigger (n = 176). A freeze-all and single blastocyst transfer strategy was used in both groups. The primary outcome was ongoing pregnancy (leading to live birth) within 6 months after randomization. A non-inferiority margin of 15% was considered.Main Results and the Role Of Chance: The IVM procedure without additional gonadotropin resulted in a lower ongoing pregnancy (leading to live birth) within 6 months after randomization compared to standard IVF treatment (22.3% vs. 50.6%; rate difference -28.3%; 95% confidence interval [CI]: -37.9% to -18.7%). Moderate-severe OHSS did not occur in the IVM group, while in the IVF group, ten women (5.7%) had moderate OHSS and one woman (0.6%) had severe OHSS. There was no statistically significant difference in the occurrence of obstetric and perinatal complications.Limitations, Reasons For Caution: The trial was conducted using an IVM protocol without additional stimulation in a single centre, which may limit its generalizability. In addition, a GnRH agonist trigger rather than hCG for IVF stimulation in women with PCOS would be more consistent with current clinical practice.Wider Implications Of the Findings: Although IVM is considered to be a convenient, inexpensive and safe alternative to IVF for women with PCOS, our results indicated that one cycle of IVM without any stimulation was inferior to one cycle of standard IVF in terms of the cumulative live birth rate. The inferiority of IVM without ovarian stimulation could be mainly due to the limitations in the developmental potential of embryos. Further IVM development should be tested and validated in a freeze-only and blastocyst transfer setting. Further RCTs are needed to evaluate the effectiveness and safety of other IVM protocols or multiple cycles of IVM compared to IVF.Study Funding/competing Interest(s): This study was supported by the National Key Research and Development Program of China (2016YFC1000201 and 2018YFC1002104) and the National Science Foundation of China (81730038).

Rationale: The long-term effects of vigorous physical activity (PA) on lung function in cystic fibrosis are unclear. Objectives: To evaluate effects of a 12-month partially supervised PA intervention using motivational feedback. Methods: In a parallel-arm multicenter randomized controlled trial (ACTIVATE-CF), relatively inactive patients aged at least 12 years were randomly assigned (1:1 ratio) to an intervention group or control group. The intervention group consented to add 3 hours of vigorous PA per week, whereas the control group was asked not to change their PA behavior. Primary endpoint was change in percent predicted FEV1 (ΔFEV1) at 6 months. Secondary endpoints included PA, exercise capacity, exercise motives, time to first exacerbation and exacerbation rates, quality of life, anxiety, depression, stress, and blood glucose control. Data were analyzed using mixed linear models. Measurements and Main Results: A total of 117 patients (40% of target sample size) were randomized to an intervention (n = 60) or control group (n = 57). After 6 months, ΔFEV1 was significantly higher in the control group compared with the intervention group (2.70% predicted [95% confidence interval, 0.13-5.26]; P = 0.04). The intervention group reported increased vigorous PA compared with the control group at each study visit, had higher exercise capacity at 6 and 12 months, and higher PA at 12 months. No effects were seen in other secondary outcomes. Conclusions: ACTIVATE-CF increased vigorous PA and exercise capacity, with effects carried over for the subsequent 6 months, but resulted in better FEV1 in the control group. [ABSTRACT FROM AUTHOR]

Rationale: Laryngeal edema is a known complication of endotracheal intubation that may cause airway obstruction upon extubation. The only test available to predict this complication is the cuff leak test (CLT). Objectives: Given the uncertainty of the CLT's clinical utility, we conducted the COMIC (Cuff Leak Test and Airway Obstruction in Mechanically Ventilated ICU Patients) pilot study to examine the feasibility of undertaking a larger trial. Methods: COMIC is a multicentered, parallel-group randomized trial performed in Canada, Saudi Arabia, and Poland. We enrolled mechanically ventilated adults admitted to the intensive care unit who were deemed ready for extubation. Those allocated to the intervention arm had the results of their CLT communicated to the healthcare team, who then decided to proceed with extubation or not. In those randomized to the control arm, the CLT results were not communicated to the healthcare team and patients were extubated, regardless of the CLT result. The primary outcomes focused on feasibility. Results: One hundred patients (56 in the intervention and 44 in the control arm) were enrolled. All feasibility criteria were met, including 1) recruitment rate of 7.6 patients/month, 2) consent rate of 88.3% (95% confidence interval [CI], 82.1-94.5%), and 3) protocol adherence of 98% (95% CI, 95-100%). There were two episodes of clinically significant stridor in the intervention group and four patients who required reintubation in each group. Conclusions: The results of the COMIC pilot trial support the feasibility of a larger trial to determine the effect of the CLT on reintubation and clinically important stridor.Clinical trial registered with www.clinicaltrials.gov (NCT03372707).

Background: There is a need for high-quality research regarding exercise interventions for persons with anxiety disorders. We investigate whether a 12-week exercise intervention, with different intensities, could reduce anxiety symptoms in patients with anxiety disorders.Methods: 286 patients were recruited from primary care in Sweden. Severity of symptoms was self-assessed using the Beck Anxiety Inventory (BAI) and the Montgomery Åsberg Depression Rating Scale (MADRS-S). Participants were randomly assigned to one of two group exercise programs with cardiorespiratory and resistance training and one control/standard treatment non-exercise group, with 1:1:1 allocation.Results: Patients in both exercise groups showed larger improvements in both anxiety and depressive symptoms compared to the control group. No differences in effect sizes were found between the two groups. To study a clinically relevant improvement, BAI and MADRS-S were dichotomized with the mean change in the control group as reference. In adjusted models the odds ratio for improved symptoms of anxiety after low-intensity training was 3.62 (CI 1.34-9.76) and after moderate/high intensity 4.88 (CI 1.66-14.39), for depressive symptoms 4.96 (CI 1.81-13.6) and 4.36 (CI 1.57-12.08) respectively. There was a significant intensity trend for improvement in anxiety symptoms.Limitations: The use of self-rating measures which bears the risk of an under- or overestimation of symptoms.Conclusions: A 12-week group exercise program proved effective for patients with anxiety syndromes in primary care. These findings strengthen the view of physical exercise as an effective treatment and could be more frequently made available in clinical practice for persons with anxiety issues.
