Context: There is a lack of consensus on the best management approach for lateral elbow tendinopathy (LET). Recently, scapular stabilizer strength impairments have been found in individuals with LET. Objective: The purpose of this study was to compare the effectiveness of local therapy (LT) treatment to LT treatment plus a scapular muscle-strengthening (LT + SMS) program in patients diagnosed with LET. Design: Prospective randomized clinical trial. Setting: Multisite outpatient physical therapy. Patients: Thirty-two individuals with LET who met the criteria were randomized to LT or LT + SMS. Interventions: Both groups received education, a nonarticulating forearm orthosis, therapeutic exercise, manual therapy, and thermal modalities as needed. Additionally, the LT + SMS group received SMS exercises. Main Outcome Measure: The primary outcome measure was the patient-rated tennis elbow evaluation; secondary outcomes included global rating of change (GROC), grip strength, and periscapular muscle strength. Outcomes were reassessed at discharge, 6, and 12 months from discharge. Linear mixed-effect models were used to analyze the differences between groups over time for each outcome measure. Results: The average duration of symptoms was 10.2 (16.1) months, and the average total number of visits was 8.0 (2.2) for both groups. There were no significant differences in gender, age, average visits, weight, or height between groups at baseline (P >.05). No statistical between-group differences were found for any of the outcome measures. There were significant within-group improvements in all outcome measures from baseline to all follow-up points (P <.05). Conclusion: The results of this pilot study suggest that both treatment approaches were equally effective in reducing pain, improving function, and increasing grip strength at discharge as well as the 6- and 12-month follow-ups. Our multimodal treatment programs were effective at reducing pain and improving function up to 1 year after treatment in a general population of individuals with LET. [ABSTRACT FROM AUTHOR]

This multicenter clinical trial of platform-switched laser-microchannel implants supports findings from a previous preclinical trial. Previous information indicated that an interimplant distance narrower than 3 mm would result in decrease in the crestal bone level, but the results of this investigation suggest that a more optimistic clinical result can be anticipated for implants and abutments with a laser-microchannel surface.

Introduction: Nurses' professional values (NPVs) and self‐efficacy (SE) are two fundamental elements in nursing care that influence its professional identity, competences, resulting in changing the behaviour of professionals and their response to the patient's health needs. The various studies produced so far have not investigated a possible relationship between these two areas. Therefore, the objective of the following study is to identify and deepen the relationship between NPV and SE, in order to improve the knowledge of these issues. Materials and methods: An observational, correlational and multicentric study has been carried out through a questionnaire based survey. The sampling was conventional. The data collection took place through Nursing Professional Values Scale, version 3 (NPVS‐3), which investigates professional values; and Nursing Professional Self‐Efficacy Scale (NPSES), which investigates self‐efficacy and a socio‐demographic questionnaire. Results: The total sample was 532 nurses and 65.6% was female, with a median age of 42 years and a median of 15 working years. Positive statistically significant correlations between the various domains of the NPVS‐3 and NPSES scales were found. These relationships also emerged in the analyses between geographical areas. Overall, the relationships between self‐efficacy and values were similar in all the analyses. Discussion: As the professional values of nurses increase in their response to the patient's health needs, self‐efficacy perceived by them increases and vice versa, significantly effecting the clinic and care outcomes of the patients and improving nursing outcomes. The stratification of the sample by geographical area regarding the relationship between age, years of work and professional values indicated that these variables strongly influence the NPV and SE of nurses. Therefore, in some contexts, more support in maintaining a stable value structure may be needed; moreover, it is necessary to incentivise nurses with more effective interventions, as an example and a basis of motivation for future generations.

Objective: Determine efficacy of the novel WiiNWalk intervention on walking-related outcomes in older adults with lower limb amputation. Design: Multi-site, parallel, evaluator-masked randomized controlled trial. Setting: Home-setting in three Canadian cities. Participants: Community-dwelling lower limb prosthesis users over 50 years of age. Interventions: The WiiNWalk group (n = 38) used modified Wii Fit activities for prosthetic rehabilitation. The attention control group (n = 33) used Big Brain Academy: Wii Degree, comprising of cognitive activities. Both groups completed a 4-week supervised phase with three 1-h sessions/week in groups of three overseen by a clinician via videoconferencing and a 4-week unstructured and unsupervised phase. Main Measures: Primary outcome was walking capacity (2 min walk test); secondary outcomes were balance confidence (activities-specific balance confidence scale), dynamic balance (four-step square test), and lower limb functioning (short physical performance battery). Outcomes were compared across time points with repeated measures analysis of covariance, adjusting for baseline and age. Results: Mean age was 65.0 (8.4) years, with 179.5 (223.5) months post-amputation and 80% transtibial amputation. No group difference in a 2 min walk test with an effect size: 1.53 95% CI [−3.17, 6.23] m. Activities balance confidence was greater in the WiiNWalk group by 5.53 [2.53, 8.52]%. No group difference in the four-step square test −0.16 [−1.25, 0.92] s, nor short physical performance battery 0.48 [−0.65, 1.61]. A post-hoc analysis showed the greatest difference in balance confidence immediately after an unsupervised phase. Conclusions: The WiiNWalk intervention improved balance confidence, but not walking-related physical function in older adult lower limb prosthesis users. Future rehabilitation games should be specific to the amputation context. Clinical Trial Registration number, NCT 01942798. [ABSTRACT FROM AUTHOR]

The de Morton Mobility Index (DEMMI) is a unidimensional clinical instrument proven reliable and valid for measuring mobility in the elderly, but its responsiveness has not been evaluated when applying the methodology recommended by COSMIN. To evaluate the responsiveness and the predictive validity of the DEMMI. Elderly people, referred for municipality-based rehabilitation, were consecutively included. Eight hypotheses regarding the relationship between the change scores in the DEMMI and other functional measures of mobility were tested by assessing the participants before and after rehabilitation. Three months after completing the rehabilitation, the participants' functional status was evaluated. 250 elderly people (mean age 85 years, 63% women) were included. The change scores in the DEMMI and the other measures correlated (r = 0.422 to 0.547), but only three out of the eight hypotheses were confirmed. A DEMMI score of less than 48 and less than 67 can predict inability of ambulating close to the participant's residence and using public transport, respectively. We found a moderate responsiveness and a high predictive validity of the DEMMI score. The DEMMI appears to be an appropriate instrument for monitoring change in mobility and predicting functional status among elderly patients undergoing rehabilitation. The de Morton Mobility Index (DEMMI) is a clinical instrument for measuring mobility. This study shows that the DEMMI was responsive to change in mobility and predicted disability among a diverse group of elderly individuals referred to rehabilitation after hospital discharge. The DEMMI is applicable as an outcome measure in trials investigating the effect of rehabilitation and for clinical decision-making concerning geriatric rehabilitation. [ABSTRACT FROM AUTHOR]

Aims: This study explored the acceptability of a workplace health promotion intervention embedded into a transition to practice (TTP) programme to assist new graduate nurses in establishing healthy dietary and physical activity (PA) behaviours from career commencement. Design: A sequential mixed methods design. Methods: The Start Healthy and Stay Healthy (SH&SH) intervention, informed by the Behaviour Change Wheel, was conducted in an Australian Local Health District. It included face‐to‐face education sessions, the use of a fitness tracker and twice‐weekly short answer messages. Participants completed three online surveys: at orientation, 6 weeks and 6 months. A sub‐sample participated in semi‐structured interviews to explore their experience of the intervention. Interview data were analysed thematically. Results: The intervention was delivered from February to December 2019. A total of 99 nurses completed the baseline survey, 62 at 6 weeks and 69 at 6 months. After 6 months, health knowledge increased as participants correctly identified recommended amounts of fruits, vegetables and PA. Fruit consumption increased at 6 months with little change to vegetable intake. Takeaway consumption decreased, but consumption of some discretionary foods increased. Across the three time points, there was a low engagement in PA during leisure time. The interviews identified three themes: (1) Support of Colleagues and Peers, (2) The Work Environment and (3) Engagement with SH&SH. Conclusion: Providing a targeted intervention for new graduate nurses embedded into a TTP programme improved their health knowledge, some dietary behaviours, and participation in PA by some participants. Impact: Ensuring a healthy nursing workforce is critical to retaining staff. Implementing a workplace health promotion intervention that targets new graduate nurses can help them adopt and maintain healthy lifestyle behaviours to support them in their future careers.

Enzalutamide resistance has been observed in approximately 50% of patients with prostate cancer (PCa) bone metastases. Therefore, there is an urgent need to investigate the mechanisms and develop strategies to overcome resistance. We observed enzalutamide resistance in bone lesion development induced by PCa cells in mouse models. We found that the bone microenvironment was indispensable for enzalutamide resistance because enzalutamide significantly inhibited the growth of subcutaneous C4-2B tumors and the proliferation of C4-2B cells isolated from the bone lesions, and the resistance was recapitulated only when C4-2B cells were co-cultured with osteoblasts. In revealing how osteoblasts contribute to enzalutamide resistance, we found that enzalutamide decreased TGFBR2 protein expression in osteoblasts, which was supported by clinical data. This decrease was possibly through PTH1R-mediated endocytosis. We showed that PTH1R blockade rescued enzalutamide-mediated decrease in TGFBR2 levels and enzalutamide responses in C4-2B cells that were co-cultured with osteoblasts. This is the first study to reveal the contribution of the bone microenvironment to enzalutamide resistance and identify PTH1R as a feasible target to overcome the resistance in PCa bone metastases.

Our understanding of stromal components, specifically cancer-associated fibroblasts (CAF), in prostate cancer (PCa), has evolved from considering these cells as inert bystanders to acknowledging their significance as players in prostate tumorigenesis. CAF are multifaceted-they promote cancer cell growth, migration and remodel the tumor microenvironment. Although targeting CAF could be a promising strategy for PCa treatment, they incorporate a high but undefined degree of intrinsic cellular heterogeneity. The interaction between CAF subpopulations, with the normal and tumor epithelium and with other cell types is not yet characterized. Defining these interactions and the critical signaling nodes that support tumorigenesis will enable the development of novel strategies to control prostate cancer progression. Here we will discuss the origins, molecular and functional heterogeneity of CAF in PCa. We highlight the challenges associated with delineating CAF heterogeneity and discuss potential areas of research that would assist in expanding our knowledge of CAF and their role in PCa tumorigenesis.

Inadequate gestational weight gain (GWG) was related with a higher incidence of small‐for‐gestational‐age (SGA) births than appropriate GWG; however, the long‐term association of maternal GWG with weight catch‐up growth in SGA children remains unknown. The objective of this study is to evaluate the associations between prepregnancy body mass index (pBMI), GWG and weight catch‐up patterns in SGA children. Data were from the Collaborative Perinatal Project, an American multicentre prospective cohort study. A total of 56,990 gravidas were recruited at the first prenatal visit, and children were followed up until school age. Maternal pBMI, GWG and physical growth of the offspring at birth, 4 months, 1 year, 4 years and 7 years old were recorded. The latent class analysis was employed to form weight catch‐up growth patterns (appropriate, excessive, slow, regression and no catch‐up patterns) in SGA children. SGA children who developed the 'appropriate catch‐up growth' pattern and whose mothers had appropriate pBMI and GWG were chosen as the reference. Associations between GWG for different pBMI and weight catch‐up patterns were analysed by multivariate logistic regression models. A total of 1619 infants (9.45%) were born term SGA. After adjusting for relevant confounders, compared with SGA children whose mothers had appropriate pBMI and GWG, SGA children with maternal prepregnancy underweight (for inadequate GWG, GWG below recommendations, adjusted OR: 2.88, 95% CI: 1.13–7.31; for appropriate/excessive GWG, adjusted OR: 3.07, 95% CI: 1.74–5.42) or with prepregnancy normal weight but inadequate GWG (adjusted OR: 2.14, 95% CI: 1.36–3.38) were at a higher risk of having the 'no catch‐up growth' pattern. We suggest that SGA children with maternal prepregnancy underweight or inadequate GWG tend to have a poor weight catch‐up growth at least until school age. [ABSTRACT FROM AUTHOR]

Aims: The purpose of this study was to determine the relationship between managerial competence level and organizational commitment among nurses in Saudi Arabia. Background: Nurse managers who have a high degree of managerial competency and/or organizational commitment are seen as role models by their employees and can affect employees' sense of belonging to the organization. Methods: A cross‐sectional, multisite study was conducted with 226 eligible nurses working at six public hospitals in Saudi Arabia. Data were collected from March through June 2021 through an online self‐administered survey. Multivariate regression was used to determine the relationship between managerial competence and organizational commitment while controlling for demographic variables. Results: Both managerial competence (M = 152.9, SD = 48.41, range: 54–216) and organizational commitment (M = 49.4, SD = 22.15, range: 18–121) were reported to be slightly moderate among the sample. A significant positive association also existed between managerial competence and organizational commitment variables (r =.510, p <.05). Conclusions: Future studies addressing potential issues for improving managerial competence and organizational commitment in clinical environments are recommended. Implications for Nursing Management: Nurse administrations should use highly standard guidelines to improve nurses' managerial competence and organizational commitment. [ABSTRACT FROM AUTHOR]

Background: Patient-reported outcome measures (PROMs) are essential clinical instruments used for assessing patient function, assisting in clinical decision making, and quantifying outcomes of surgical and nonsurgical management. However, PROMs are often designed using patients with preexisting pathology and typically assume that a patient without the pathology would have a perfect or near perfect score. This may result in unrealistic expectations or falsely underestimate how well a patient is doing after treatment. The influence of age on PROMs about the hip of healthy individuals has not been studied. Hypothesis: We hypothesize that in asymptomatic individuals hip-specific PROM scores will decrease in an age-dependent manor. Study Design: Cross-sectional study; Level of evidence, 3. Methods: In this multicenter survey study, volunteers who denied preexisting hip pathology and previous hip surgery completed 3 PROMs online or as traditional paper questionnaires. The International Hip Outcome Tool (iHOT), the modified Harris Hip Score (mHHS), and the Hip Outcome Score–Activities of Daily Living (HOS-ADL) and HOS—Sport were completed. Analysis of variance with a Tukey post hoc test was used to analyze differences in PROMs among subgroups. An independent-samples Student t test and a χ2 test were used to analyze differences in continuous and categorical data, respectively. Results: In total 496, 571, 534, and 532 responses were collected for the iHOT, mHHS, HOS-ADL, and HOS–Sport, respectively. Respondents' PROMs were scored and arranged into 3 groups by age: <40 years, 40 to 60 years, and >60 years. The iHOT, mHHS, HOS-ADL, and HOS–Sport of these asymptomatic respondents all decreased in an age-dependent manner: iHOT (<40, 94.1; 40-60, 92.4; >60, 87.0), mHHS (<40, 94.8; 40-60, 91.3; >60, 89.1), HOS-ADL (<40, 98.4; 40-60, 95.0; >60, 90.9), and HOS–Sport (<40, 95.7; 40-60, 82.9; >60, 72.9) (analysis of variance between-group differences, P <.05). Conclusion: This study demonstrated that the iHOT, mHHS, and HOS-ADL and HOS–Sport scores in asymptomatic people decrease in an age-dependent manner. It is important to compare a patient's outcome scores with the age-normalized scores to establish an accurate reference frame with which to interpret outcomes. [ABSTRACT FROM AUTHOR]

Aims: To describe beginning nursing student learning styles and to determine whether there are relationships between learning style and sociodemographic or educational background. We also aim to compare these data with the normative values of the 3.1 version of the Kolb learning style inventory and verify its reliability. Background/Literature: Learning style is related to the way in which an individual interacts with learning conditions, involving cognitive, affective, physical and environmental aspects. In nursing education, few studies have focused on knowing the learning styles of beginning nursing students, despite the need for students to develop critical thinking skills required of nurses. Design: Descriptive, cross‐sectional, correlational, multi‐site study. Method: The study took place at five universities in Brazil and one university in the United States. Data were collected from a sample of beginning nursing students (n = 176) in 2019, using the Portuguese and English 3.1 versions of Kolb's learning style inventory. Results: Most students' learning styles were classified as divergers (34.10%), while 28.41% were assimilators, 23.86% were accommodators and 13.63% were convergers. Kolb describes learning as a four‐stage cyclical process grounded in experience. The mean score of one learning stage, the concrete experience, showed those who attended public high schools compared with private high schools was higher (mean = 26.22; p =.0019), and there were different results between Brazilian state universities, Brazilian federal universities and the American university (p =.0149). Conclusion: The diverger style was the most common among beginning nursing students in Brazil and the United States. There was a significant relationship between learning style, the educational background of students, the type of institution they attend and their previous experience with some active learning methodologies. Relevance to clinical practice: Aligned with Kolb's experiential learning theory, nurse educators must be aware of student learning styles so they may use teaching strategies to meet their students' needs.

Aims and objectives: To describe caregiver contribution (CC) to ostomy self‐care and identify its associated variables among caregivers of ostomy patients. Background: Self‐care is essential for ostomy patients, but it can be difficult to perform. In these cases, caregivers play a key role in promoting self‐care behaviours. So far, the CC to ostomy self‐care has not been investigated thoroughly. Design: This is a cross‐sectional and multicentre study conducted at seven outpatient clinics of two Italian regions. Methods: We recruited 252 caregivers between February 2017–May 2018. The Caregiver Contribution to Ostomy Self‐Care Index (CC‐OSCI) was used to measure CC to ostomy self‐care. Three multivariable linear regression models were fitted to identify variables associated with CC dimensions (maintenance, monitoring and management). The STROBE checklist was used to report the present study. Results: The sample (mean age = 58.73, SD = 13.98) was mostly female (80.60%), unemployed (58.70%) and resided with the patient (81.00%). Caregivers being employed and those declaring more hours of contribution per week were associated with a significantly lower contribution to self‐care maintenance. Caregivers with lower levels of education and those residing with the patient were less likely to contribute to CC to self‐care monitoring. Spousal caregivers and those with higher preparedness contributed significantly lower to CC to self‐care management. Conclusions: We found a variety of sociodemographic factors associated with CC to ostomy self‐care. Relevance to clinical practice: Sociodemographic variables associated with CC to ostomy self‐care can help clinicians develop more tailored educational interventions for caregivers who find their contribution challenging.

Introduction: Menthol cigarettes are popular among young adults and are disproportionately used by African American smokers. Menthol's minty and cooling sensations have been hypothesized to enhance the appeal and reinforcement of smoking; however, differences in menthol's subjective appeal across races have been inconsistent. This secondary data analysis examined differences in subjective appeal for smoking menthol versus non-menthol cigarettes between African American and White young adult smokers.Methods: Young adults (ages 18-24) recruited from Amazon Mechanical Turk (December 2018-January 2019) completed an online survey of tobacco use behavior. Past year smokers (n = 1726) answered questions about subjective responses to smoking (reward, satisfaction, throat hit, craving reduction, and aversion).Results: Significantly more African American (73.2%) compared to White (52.4%) smokers preferred menthol cigarettes (p < .001). Menthol smokers reported greater positive and negative subjective responses to smoking than non-menthol smokers. Positive and negative subjective response were both associated with greater smoking intensity and lower cigarette harm perceptions. Interactions of menthol preference and race on indices of subjective appeal also emerged. African American non-menthol smokers reported lower levels of satisfaction, reward, and craving reduction compared to White non-menthol smokers.Conclusions: The relationship between menthol preference and subjective response to smoking differs by race. Menthol is rated as more appealing than non-menthol smoking, and appeal indices were linked to smoking intensity and lower harm perceptions, indicating greater abuse liability of menthol cigarettes. Policies that ban menthol cigarettes may have a particularly positive impact on the cigarette smoking of African American young adult smokers.Implications: The FDA issued an Advanced Notice of Proposed Rule Making to examine the role menthol in tobacco products to inform regulations to restrict or ban flavors. This study showed that menthol smokers reported greater appeal to smoking than non-menthol smokers; and an interaction of race x menthol preference showed African American non-menthol smokers reported the lowest levels of appeal to smoking. Multiple indices of cigarette appeal were positively correlated with smoking intensity and lower cigarette harm perceptions, highlighting the addiction potential of menthol cigarettes. Findings suggest a menthol cigarette ban could help reduce tobacco use among young adults. [ABSTRACT FROM AUTHOR]

Elder abuse and neglect (EAN) goes largely unrecognized and underreported globally by health care professionals. Despite acknowledging their role to intervene elder abuse, health care professionals lacked knowledge and skills in this issue. This is a single-blinded, three-armed, cluster randomized controlled trials aimed to evaluate the effectiveness of the face-to-face I mproving N urses' d E tection and manag E ment of el D er abuse and neglect (I-NEED) intensive training program and I-NEED educational video in improving primary care nurses' knowledge, attitude, and confidence to intervene EAN; 390 primary care nurses were randomized equally into two intervention groups—ITP group (intensive training program) and ITP+ group (intensive training program and educational video)—and a control group. The knowledge, attitudes, and confidence to intervene EAN were measured using questionnaires at four intervals during 6-month follow-up. A total of 269 primary care nurses participated in this study. There was a significant increase in knowledge, attitude, and confidence to intervene EAN immediately post intervention observed in both intervention groups compared to the control group (p <.001). At the end of sixth month, there was an increase of knowledge favoring ITP group than the ITP+ group (p <.001). There is, however, no significant difference in attitude score between ITP and ITP+ group. There is a significant difference of confidence to intervene among the participants between both intervention groups with ITP+ participants reporting higher scores post intervention (p <.05). An intensive training module improved the knowledge, attitude, and confidence to intervene EAN. Other co-existing barriers for abuse victims getting help, resources, policy, and law of EAN need further highlights. [ABSTRACT FROM AUTHOR]

Background and Purpose: Dementia affects physical as well as cognitive performance. In individuals with dementia (IWD), decline in physical performance increases with disease progression and is associated with higher functional dependence and decreased quality of life. It is paramount to examine factors that potentially preserve physical performance in IWD, particularly in light of conflicting findings on the effectiveness of physical activity interventions on physical performance of IWD, mainly due to limited number of high-quality studies, large heterogeneity in methods used, or insufficient reporting of methods. The aim of this study was to investigate the effects of a 16-week multimodal exercise program (MEP) combining physical and cognitive tasks on physical performance in IWD, and to identify individual characteristics of MEP responders. Methods: A multicenter randomized controlled trial with assessment methods identified by an expert panel was conducted. We included 319 IWD of mild to moderate severity, older than 65 years, who underwent a standardized MEP specifically designed for IWD. At baseline and immediately after the MEP, we assessed physical performance (ie, mobility, balance, and strength) and function of lower extremities (primary outcomes). Potential effects of the MEP on physical performance were identified using 2-factor analyses of variance with repeated measurements within 2 samples (ie, intention-to-treat and per-protocol sample). Additionally, we compared characteristics related to physical performance between positive, non-, and negative responders. Results and Discussion: Neither analysis procedure revealed statistically significant time×group effects. However, 28% to 40% of participants were positive responders with regard to balance, and strength and function of lower extremities; and these persons had statistically significant lower baseline performance in the corresponding assessments. Conclusions: This randomized controlled trial revealed no overall effects of the MEP on physical performance, probably due to high heterogeneity of the study sample. Findings in responder analysis showed that IWD with lower physical performance at baseline tended to benefit more than those with higher baseline performance. Thus, a higher degree of individualization of the MEP depending on baseline performance on IWD may improve overall MEP effectiveness. [ABSTRACT FROM AUTHOR]

Recovery from stroke aims at regaining mobility through performing activities. However, research studies on time use in rehabilitation environments consistently show low activity levels of stroke patients outside their scheduled therapies. It is not clear whether the architectural layout of clinics is related to patients' activity. This study examined the nonscheduled (voluntary) activities of stroke patients during an ordinary day in a rehabilitation clinic to investigate whether and how the built environment contributes to stroke patients' independent activities. Patient shadowing was used in seven neurological rehabilitation clinics. Ten patients were observed per clinic (n = 70), each patient for 12 consecutive hours (total 840 hours). Their paths, activities, locations and traveled distances were recorded in relation to the clinics' layouts. Patients spent around 50% of the observed time in their rooms. The frequency of nonscheduled activity was low in all participating clinics (Mdn = 21,2%, IQR 6,5%–21%) compared to the scheduled activity. The median length of the nonscheduled paths for all patients was 43,42 m (average 46,97 m), with significantly longer scheduled paths (average 89,11 m, Mdn = 77,06 m, Mann-Whitney U = 536, n1 = 762, n2 = 225, p <.001, two-tailed). Corridors and seating areas in the corridors were the most frequent destinations of patients' nonscheduled paths. The clinic with the most frequent nonscheduled activity had a distinctive spatial distribution of dining and living spaces. There is a need to change the architectural layout of rehabilitation clinics to better support patients' nonscheduled activity. [ABSTRACT FROM AUTHOR]

This study aimed to assess the performance of waist-to-height ratio (WHtR) in the prediction of metabolic syndrome and to determine the appropriate cutoff value in Thai adolescents. Demographic data, blood pressure, fasting blood glucose, and lipid profile were obtained from the Thai National Health Examination Survey V database. The performances of WHtR, waist circumference, body mass index (BMI), and BMI z -score were analyzed by the receiver operating characteristics. Among 2644 adolescents, metabolic syndrome was identified in 4.27%. The areas under the receiver operating characteristic curves of WHtR, waist circumference, BMI, and BMI z -score were comparable (0.924-0.960). Performance of WHtR was more constant across age groups compared with other parameters. Using the cutoff value of WHtR at 0.5 resulted in the sensitivity and specificity of 98.5%/83.4% and 88.9%/86.0% in males and females, respectively. In conclusion, the cutoff value of WHtR at 0.5 provided good sensitivity and specificity for identifying metabolic syndrome in both genders. However, the other clinical risk factors or more definite scores should be considered when further assessment. [ABSTRACT FROM AUTHOR]

Objective: To summarise evidence of the effects of blood pressure (BP)-lowering interventions after acute spontaneous intracerebral haemorrhage (ICH).Methods: A prespecified systematic review of the Cochrane Central Register of Controlled Trials, EMBASE and MEDLINE databases from inception to 23 June 2020 to identify randomised controlled trials that compared active BP-lowering agents versus placebo or intensive versus guideline BP-lowering targets for adults <7 days after ICH onset. The primary outcome was function (distribution of scores on the modified Rankin scale) 90 days after randomisation. Radiological outcomes were absolute (>6 mL) and proportional (>33%) haematoma growth at 24 hours. Meta-analysis used a one-stage approach, adjusted using generalised linear mixed models with prespecified covariables and trial as a random effect.Results: Of 7094 studies identified, 50 trials involving 11 494 patients were eligible and 16 (32.0%) shared patient-level data from 6221 (54.1%) patients (mean age 64.2 [SD 12.9], 2266 [36.4%] females) with a median time from symptom onset to randomisation of 3.8 hours (IQR 2.6-5.3). Active/intensive BP-lowering interventions had no effect on the primary outcome compared with placebo/guideline treatment (adjusted OR for unfavourable shift in modified Rankin scale scores: 0.97, 95% CI 0.88 to 1.06; p=0.50), but there was significant heterogeneity by strategy (pinteraction=0.031) and agent (pinteraction<0.0001). Active/intensive BP-lowering interventions clearly reduced absolute (>6 ml, adjusted OR 0.75, 95%CI 0.60 to 0.92; p=0.0077) and relative (≥33%, adjusted OR 0.82, 95%CI 0.68 to 0.99; p=0.034) haematoma growth.Interpretation: Overall, a broad range of interventions to lower BP within 7 days of ICH onset had no overall benefit on functional recovery, despite reducing bleeding. The treatment effect appeared to vary according to strategy and agent.Prospero Registration Number: CRD42019141136. [ABSTRACT FROM AUTHOR]

Background: Premorbid body mass index, physical activity, diabetes and cardiovascular disease have been associated with an altered risk of developing amyotrophic lateral sclerosis (ALS). There is evidence of shared genetic risk between ALS and lipid metabolism. A very large prospective longitudinal population cohort permits the study of a range of metabolic parameters and the risk of subsequent diagnosis of ALS.Methods: The risk of subsequent ALS diagnosis in those enrolled prospectively to the UK Biobank (n=502 409) was examined in relation to baseline levels of blood high and low density lipoprotein (HDL, LDL), total cholesterol, total cholesterol:HDL ratio, apolipoproteins A1 and B (apoA1, apoB), triglycerides, glycated haemoglobin A1c (HbA1c) and creatinine, plus self-reported exercise and body mass index.Results: Controlling for age and sex, higher HDL (HR 0.84, 95% CI 0.73 to 0.96, p=0.010) and apoA1 (HR 0.83, 95% CI 0.72 to 0.94, p=0.005) were associated with a reduced risk of ALS. Higher total cholesterol:HDL was associated with an increased risk of ALS (HR 1.17, 95% CI 1.05 to 1.31, p=0.006). In models incorporating multiple metabolic markers, higher LDL or apoB was associated with an increased risk of ALS, in addition to a lower risk with higher HDL or apoA. Coronary artery disease, cerebrovascular disease and increasing age were also associated with an increased risk of ALS.Conclusions: The association of HDL, apoA1 and LDL levels with risk of ALS contributes to an increasing body of evidence that the premorbid metabolic landscape may play a role in pathogenesis. Understanding the molecular basis for these changes will inform presymptomatic biomarker development and therapeutic targeting. [ABSTRACT FROM AUTHOR]

Objective: Neurofilaments are the major scaffolding proteins for the neuronal cytoskeleton, and variants in NEFH have recently been described to cause axonal Charcot-Marie-Tooth disease type 2CC (CMT2CC).Methods: In this large observational study, we present phenotype-genotype correlations on 30 affected and 3 asymptomatic mutation carriers from eight families.Results: The majority of patients presented in adulthood with motor-predominant and lower limb-predominant symptoms and the average age of onset was 31.0±15.1 years. A prominent feature was the development of proximal weakness early in the course of the disease. The disease progressed rapidly, unlike other Charcot-Marie-Tooth disease (CMT) subtypes, and half of the patients (53%) needed to use a wheelchair on average 24.1 years after symptom onset. Furthermore, 40% of patients had evidence of early ankle plantarflexion weakness, a feature which is observed in only a handful of CMT subtypes. Neurophysiological studies and MRI of the lower limbs confirmed the presence of a non-length-dependent neuropathy in the majority of patients.All families harboured heterozygous frameshift variants in the last exon of NEFH, resulting in a reading frameshift to an alternate open reading frame and the translation of approximately 42 additional amino acids from the 3' untranslated region (3'-UTR).Conclusions: This phenotype-genotype study highlights the unusual phenotype of CMT2CC, which is more akin to spinal muscular atrophy rather than classic CMT. Furthermore, the study will enable more informative discussions on the natural history of the disease and will aid in NEFH variant interpretation in the context of the disease's unique molecular genetics.

Background: Gestational diabetes (GDM) impacts 8-18% of pregnancies and greatly increases both maternal and child risk of developing non-communicable diseases such as type 2 diabetes and obesity. Whilst lifestyle interventions in pregnancy and postpartum reduce this risk, a research translation gap remains around delivering implementable interventions with adequate population penetration and participation. Impact Diabetes Bump2Baby is an implementation project of an evidence-based system of care for the prevention of overweight and obesity. Bump2Baby and Me is the multicentre randomised controlled trial investigating the effectiveness of a mHealth coaching programme in pregnancy and postpartum for women at high risk of developing GDM.Methods: Eight hundred women will be recruited in early pregnancy from 4 clinical sites within Ireland, the UK, Spain, and Australia. Women will be screened for eligibility using the validated Monash GDM screening tool. Participants will be enrolled from 12 to 24 weeks' gestation and randomised on a 1:1 basis into the intervention or control arm. Alongside usual care, the intervention involves mHealth coaching via a smartphone application, which uses a combination of synchronous and asynchronous video and text messaging, and allows for personalised support and goal setting with a trained health coach. The control arm receives usual care. All women and their children will be followed from early pregnancy until 12 months postpartum. The primary outcome will be a difference in maternal body mass index (BMI) of 0.8 kg/m2 at 12 months postpartum. Secondary maternal and infant outcomes include the development of GDM, gestational weight gain, pregnancy outcomes, improvements in diet, physical activity, sleep, and neonatal weight and infant growth patterns. The 5-year project is funded by the EU Commission Horizon 2020 and the Australian National Health and Medical Research Council. Ethical approval has been received.Discussion: Previous interventions have not moved beyond tightly controlled efficacy trials into routine service delivery. This project aims to provide evidence-based, sustainable support that could be incorporated into usual care for women during pregnancy and postpartum. This study will contribute evidence to inform the early prevention of non-communicable diseases like obesity and diabetes in mothers and the next generation.Trial Registration: Australian New Zealand Clinical Trials Registry ACTRN12620001240932 .

To compare stroke-specific health related quality of life in two country-regions with organisational differences in subacute rehabilitation services, and to reveal whether organisational factors or individual factors impact outcome. A prospective multicentre study with one-year follow-up of 369 first-ever stroke survivors with ischaemic or haemorrhagic stroke, recruited from stroke units in North Norway (n = 208) and Central Denmark (n = 161). The 12-domain Stroke-Specific Quality of Life scale was the primary outcome-measure. The Norwegian participants were older than the Danish (Mage= 69.8 vs. 66.7 years, respectively), had higher initial stroke severity, and longer stroke unit stays. Both cohorts reported more problems with cognitive, social, and emotional functioning compared to physical functioning. Two scale components were revealed. Between-country differences in the cognitive-social-mental component showed slightly better function in the Norwegian participants. Depression, anxiety, pre-stroke dependency, initial stroke severity, and older age were substantially associated to scale scores. Successful improvements in one-year functioning in both country-regions may result from optimising long-term rehabilitation services to address cognitive, emotional, and social functioning. Stroke-Specific Quality of Life one-year post-stroke could be explained by individual factors, such as pre-stroke dependency and mental health, rather than differences in the organisation of subacute rehabilitation services. The stroke-specific health related quality of life (SS-QOL) assessment tool captures multidimensional effects of a stroke from the perspective of the patient, which is clinically important information for the rehabilitation services. The cognitive-social-mental component and the physical health component, indicate specific functional problems which may vary across and within countries and regions with different organisation of rehabilitation services. For persons with mild to moderate stroke, longer-term functional improvements may be better optimised if the rehabilitation services particularly address cognitive, emotional, and social functioning.

Background: Cannabis use among pregnant and lactating people is increasing, despite clinical evidence showing that cannabis use may be associated with low birth weight and childhood developmental deficits. Our objective was to understand why pregnant and lactating people use cannabis and how these motivations change across perinatal stages.Methods: Using qualitative, constructivist grounded theory methodology, we conducted telephone and virtual interviews with 52 individuals from across Canada. We selected participants using maximum variation and theoretical sampling. They were eligible if they had been pregnant or lactating within the past year and had decided to continue, cease or decrease their cannabis use during the perinatal period.Results: We identified 3 categories of reasons that people use cannabis during pregnancy and lactation: sensation-seeking for fun and enjoyment; symptom management of chronic conditions and conditions related to pregnancy; and coping with the unpleasant, but nonpathologized, experiences of life. Before pregnancy, participants endorsed reasons for using cannabis in these 3 categories in similar proportions, with many offering multiple reasons for use. During pregnancy, reasons for use shifted primarily to symptom management. During lactation, reasons returned to resemble those expressed before pregnancy.Interpretation: In this study, we showed that pregnant and lactating people use cannabis for many reasons, particularly for symptom management. Reasons for cannabis use changed across reproductive stages. The dynamic nature of the reasons for use across stages speaks to participant perception of benefits and risks, and perhaps a desire to cast cannabis use during pregnancy as therapeutic because of perceived stigma.

Introduction: Gastrointestinal stromal tumor (GIST) is the most common gastrointestinal soft tissue tumor. Clinical diagnosis mainly relies on enhanced CT, endoscopy and endoscopic ultrasound (EUS), but the misdiagnosis rate is still high without fine needle aspiration biopsy. We aim to develop a novel diagnostic model by analyzing the preoperative data of the patients.Methods: We used the data of patients who were initially diagnosed as gastric GIST and underwent partial gastrectomy. The patients were randomly divided into training dataset and test dataset at a ratio of 3 to 1. After pre-experimental screening, max depth = 2, eta = 0.1, gamma = 0.5, and nrounds = 200 were defined as the best parameters, and in this way we developed the initial extreme gradient-boosting (XGBoost) model. Based on the importance of the features in the initial model, we improved the model by excluding the hematological features. In this way we obtained the final XGBoost model and underwent validation using the test dataset.Results: In the initial XGBoost model, we found that the hematological indicators (including inflammation and nutritional indicators) examined before the surgery had little effect on the outcome, so we subsequently excluded the hematological indicators. Similarly, we also screened the features from enhanced CT and ultrasound gastroscopy, and finally determined the 6 most important predictors for GIST diagnosis, including the ratio of long and short diameter under CT, the CT value of the tumor, the enhancement of the tumor in arterial period and venous period, existence of liquid area and calcific area inside the tumor under EUS. Round or round-like tumors with a CT value of around 30 (25-37) and delayed enhancement, as well as liquid but not calcific area inside the tumor best indicate the diagnosis of GIST.Conclusions: We developed a model to further differential diagnose GIST from other tumors in initially clinical diagnosed gastric GIST patients by analyzing the results of clinical examinations that most patients should have completed before surgical resection.

Objective: Familial hypercholesterolaemia (FH) is a common inherited disorder that remains mostly undetected in the general population. Through FH case-finding and direct access to genetic testing in primary care, this intervention study described the genetic and lipid profile of patients found at increased risk of FH and the outcomes in those with positive genetic test results.Methods: In 14 Central England general practices, a novel case-finding tool (Familial Hypercholetserolaemia Case Ascertainment Tool, FAMCAT1) was applied to the electronic health records of 86 219 patients with cholesterol readings (44.5% of total practices' population), identifying 3375 at increased risk of FH. Of these, a cohort of 336 consenting to completing Family History Questionnaire and detailed review of their clinical data, were offered FH genetic testing in primary care.Results: Genetic testing was completed by 283 patients, newly identifying 16 with genetically confirmed FH and 10 with variants of unknown significance. All 26 (9%) were recommended for referral and 19 attended specialist assessment. In a further 153 (54%) patients, the test suggested polygenic hypercholesterolaemia who were managed in primary care. Total cholesterol and low-density lipoprotein-cholesterol levels were higher in those patients with FH-causing variants than those with other genetic test results (p=0.010 and p=0.002).Conclusion: Electronic case-finding and genetic testing in primary care could improve identification of FH; and the better targeting of patients for specialist assessment. A significant proportion of patients identified at risk of FH are likely to have polygenic hypercholesterolaemia. There needs to be a clearer management plan for these individuals in primary care.Trial Registration Number: NCT03934320. [ABSTRACT FROM AUTHOR]

Background: Preeclampsia is associated with increased risk of future heart failure (HF), but the relationship between preeclampsia and HF subtypes are not well-established.Objectives: The objective of this analysis was to identify the risk of HF with preserved ejection fraction (HFpEF) following a delivery complicated by preeclampsia/eclampsia.Methods: A retrospective cohort study using the New York and Florida state Healthcare Cost and Utilization Project State Inpatient Databases identified delivery hospitalizations between 2006 and 2014 for women with and without preeclampsia/eclampsia. The authors identified women admitted for HF after discharge from index delivery hospitalization until September 30, 2015, using International Classification of Diseases-9th Revision-Clinical Modification diagnosis codes. Patients were followed from discharge to the first instance of primary outcome (HFpEF hospitalization), death, or end of study period. Secondary outcomes included hospitalization for any HF and HF with reduced ejection fraction, separately. The association between preeclampsia/eclampsia and HFpEF was analyzed using Cox proportional hazards models.Results: There were 2,532,515 women included in the study: 2,404,486 without and 128,029 with preeclampsia/eclampsia. HFpEF hospitalization was significantly more likely among women with preeclampsia/eclampsia, after adjusting for baseline hypertension and other covariates (aHR: 2.09; 95% CI: 1.80-2.44). Median time to onset of HFpEF was 32.2 months (interquartile range: 0.3-65.0 months), and median age at HFpEF onset was 34.0 years (interquartile range: 29.0-39.0 years). Both traditional (hypertension, diabetes mellitus) and sociodemographic (Black race, rurality, low income) risk factors were also associated with HFpEF and secondary outcomes.Conclusions: Preeclampsia/eclampsia is an independent risk factor for future hospitalizations for HFpEF.

Peristomal skin problems are common in ostomy patients and are connected to decreased quality of life and patient independence, as well as increased treatment costs. This study analysed the factors related to peristomal skin changes in order to better define the clinical profile of patients with optimal peristomal skin status. Secondary analysis of data from a nationwide, cross-sectional, retrospective, multicentre study performed in Spain (Uses and Attitudes in Ostomy) (Bueno Cruz et al, 2021) evaluated clinical data, including demographics, preoperative stoma site marking, type of ostomy, device used, frequency of leakage and scores from the Ostomy Skin Tool (OST) and quality of life (QoL) questionnaires. Risk factors for peristomal skin changes were analysed using multivariate analysis, and a predictive nomogram to anticipate optimal peristomal skin status (defined here as discolouration (D), erosion (E), and tissue overgrowth (T) (DET) score of 0) was developed. Some 871 patients with an ostomy using different commercial devices in Spain were evaluated. Multivariate analysis to predict optimal peristomal skin status revealed leakage frequency, patient age, type of ostomy, preoperative siting and type of baseplate used were independent predictors of peristomal skin status. Optimal peristomal skin care should be a treatment goal for nurse specialists in stomal therapy, and its individual influencing variables should be taken into account by nurses specialising in ostomy care.

Background: Jurisdictions participating in Strengthening the US Response to Resistant Gonorrhea (SURRG) implemented specimen collection for culture and antimicrobial susceptibility testing from a sample of persons of all genders (at multiple anatomic sites) attending sexually transmitted disease clinics and community clinics. We describe the percentage and characteristics of patients whose isolates demonstrated reduced susceptibility (RS) to azithromycin, ceftriaxone, or cefixime.Methods: We included patients from clinics that participated in SURRG whose isolates underwent antimicrobial susceptibility testing by Etest. We defined RS as azithromycin minimum inhibitory concentrations (MICs) ≥2 μg/mL (AZM-RS), ceftriaxone MICs ≥0.125 μg/mL (CRO-RS), or cefixime MICs ≥0.25 μg/mL (CFX-RS). Patients with repeated infections appeared >1 time in the data. We calculated the frequency and percentage of patients with an isolate demonstrating RS by epidemiological characteristics.Results: During the period 2018-2019, 10,013 patients from 8 jurisdictions provided 10,735 isolates. Among 10,013 patients, 11.0% (n = 1099) had ≥1 isolate with AZM-RS (range by jurisdiction, 2.5%-18.0%). Approximately 11.3% of 8771 of patients visiting sexually transmitted disease clinics and approximately 8.8% of 1242 patients visiting community clinics had an AZM-RS isolate. Nearly 6% of 1013 females had an AZM-RS isolate; among males, the percents of patients with an AZM-RS isolate were 17.7% among 4177 men who have sex only with men and 6.1% among 3581 men who have sex only with women. Few (0.4%) patients had isolates with CFX-RS (n = 40) or CRO-RS (n = 43).Conclusions: Although infections with reduced cephalosporin susceptibility were rare, AZM-RS infections were prevalent in this sample of patients in multiple jurisdictions and across gender and gender of sex partner categories.

Introduction: This longitudinal study designed and tested the validity of a new measure of prosocial risk taking - risks that individuals take in order to help others.Methods: The sample was racially and ethnically diverse adolescents in the rural Southeastern United States (N = 867; Mage = 12.82 years, 10-14 years at Wave 1; 50% Girls, 33% White non-Latinx, 27% Latinx, 20% Black, 20% Mixed/Other race/ethnicity). Adolescents completed self-report measures of the new prosocial risk-taking scale at baseline and one- and two-year follow-ups.Results: Confirmatory factor analysis demonstrated excellent model fit with a 6-item single factor score. Further, the scale demonstrated good test-retest reliability at one and two-year follow ups. The scale also demonstrated convergent validity, such that prosocial risk taking was positively correlated with prosocial tendencies, empathy, and sensation seeking, and negatively correlated with negative risk-taking behavior and risk tolerance. Finally, we found significant differences by race/ethnicity (but not by gender) in prosocial risk taking, which were not attributable to measurement invariance, and should be interpreted in the context of ongoing societal inequalities between youth.Conclusions: The new Prosocial Risk-Taking Scale yielded reliable scores in our sample. It may be used in future research to investigate individual differences in adolescents' prosocial risk taking, developmental change in prosocial risk taking, and the significance of prosocial risk taking for adolescents' emotional and social adaptation.

Time to event outcomes is commonly encountered in epidemiologic research. Multiple papers have discussed the inadequacy of using the hazard ratio as a causal effect measure due to its noncollapsibility and the time-varying nature. In this paper, we further clarified that the hazard ratio might be used as a conditional causal effect measure, but it is generally not a valid marginal effect measure, even under randomized design. We proposed to use the restricted mean survival time (RMST) difference as a causal effect measure, since it essentially measures the mean difference over a specified time horizon and has a simple interpretation as the area under survival curves. For observational studies, propensity score adjustment can be implemented with RMST estimation to remove observed confounding bias. We proposed a propensity score stratified RMST estimation strategy, which performs well in our simulation evaluation and is relatively easy to implement for epidemiologists in practice. Our stratified RMST estimation includes two different versions of implementation, depending on whether researchers want to involve regression modeling adjustment, which provides a powerful tool to examine the marginal causal effect with observational survival data.

Purpose: This study examines risk factors for heat-related mortality due to hyperthermia in emergency department patients, a vulnerable population.Methods: This matched case-control study used statewide, longitudinally linked emergency department (ED) data and death records from California. Cases comprised California residents (≥18 years) who presented to a state-licensed ED and died of hyperthermia during the study period (2009-2012). For each case, up to five ED patients were randomly selected as live controls and matched on sex and age. Patients' demographic characteristics and history of ED utilization for alcohol use, drug use, psychiatric disorders, heart-related conditions, chronic respiratory disease, neurodegenerative disorders, and cerebrovascular disease were assessed in relationship to hyperthermia mortality.Results: Using multivariate conditional logistic regression models, hyperthermia mortality cases had higher odds of prior ED utilization for alcohol use (OR = 11.16, 95% CI = 3.87, 32.17) compared to controls. Cases were also more likely than controls to have Medicare insurance (OR = 5.80, 95% CI = 1.70, 15.15) or self-pay (OR = 5.39, 95% CI = 1.73, 16.79), at their most recent ED visit.Conclusions: ED patients presenting with alcohol problems may face increased risk of hyperthermia mortality. To help reduce heat-related mortality, EDs should consider interventions that target patients vulnerable to heat exposure. [ABSTRACT FROM AUTHOR]

Purpose: We examined psychosocial factors (housing, drug use, incarceration history or mental health) and care factors (comorbidities and acute care) associated with all-cause and HIV-related mortality while enrolled in the New York City Ryan White HIV Care Coordination Program (CCP), an intensive case management program for people with barriers to HIV care and treatment.Methods: We used hazards regression (HR) to understand factors associated with mortality.Results: 8,135 people (13,479.4 person years [PY]) enrolled in the CCP from March 2011 to December 2016. The all-cause mortality rate while enrolled was 28.8 per 1000 PY (N = 388), with 43% of deaths (N = 167) related to HIV (12.4 per 1000 PY). Controlling for demographics and clinical status, the variables associated with increased hazards of all-cause mortality included hospitalizations or emergency-department visits prior to enrollment (aHRHospitalizations: 2.54; 95% Confidence Interval 2.07-3.11 and aHRED: 1.54; 1.24-1.92) or a diabetes or Hepatitis C diagnosis at enrollment (aHRDiabetes: 1.80; 1.36-2.37 and aHRHCV: 1.78; 1.37-2.30). These factors also increased the hazards of HIV-related mortality.Conclusions: CCP and similar case management programs should systematically screen enrolling clients for a history of acute care and comorbidities, as they may be important markers of need for more intensive engagement and follow-up to prevent death.

Purpose: Migrating from Mexico to the U.S. is a major, stressful life event with potentially profound influences on mental health. However, estimating the health effects of migration is challenging because of differential selection into migration and time-varying confounder mediators of migration effects on health.Methods: We pooled data from the Mexican Health and Aging Study (N = 17,771) and Mexican-born U.S. Health and Retirement Study (N = 898) participants to evaluate the effects of migration to the U.S. (at any age and in models for migration in childhood or adulthood) on depressive symptom-count, measured with a modified Centers for Epidemiologic Studies-Depression scale. We modeled probability of migrating in each year of life from birth to either age at initial migration to the U.S. or enrollment and used these models to calculate inverse probability of migration weights. We applied the weights to covariate-adjusted negative binomial GEE models, estimating the ratio of average symptom-count associated with migration.Results: Mexico to U.S. migration was unrelated to depressive symptoms among men (ratio of average symptom-count= 0.98 [95% CI: 0.89, 1.08]) and women (ratio of average symptom-count = 1.00 [95% CI: 0.92, 1.09]). Results were similar for migration in childhood, early adulthood, or later adulthood.Conclusions: In this sample of older Mexican-born adults, migration to the U.S. was unrelated to depressive symptoms.

Background: There are two alternative mechanisms, elucidating the reciprocal relationship between self-efficacy and social support when explaining health outcomes: self-efficacy beliefs may operate as the establisher of social support (the cultivation model) or social support may enable the formation of self-efficacy beliefs (the enabling model).Purpose: In line with the cultivation hypothesis, it was tested if self-efficacy (measured in parents and children) would indirectly predict parental and child moderate-to-vigorous physical activity (MVPA), via the mediator, social support (parent-provided, child-received). In line with the enabling hypothesis, it was tested if social support would predict MVPA indirectly, via the mediator, self-efficacy.Methods: A total of 879 parent-child dyads (1758 individuals; 52.4% girls, aged 5-11 years old, 83.2% mothers) provided self-reports at the baseline (T1) and the 7- to 8-month follow-up (T2). Body weight and height were measured objectively. Manifest path analyses were performed, controlling for the baseline levels of the mediator and dependent variables.Results: A similar number of significant simple indirect effects was found for the cultivation and the enabling model. Across the models, the indirect effects followed similar patterns: (a) within-individual indirect effects in children; (b) across-individual indirect effects, with the independent variable measured in children and the mediator/dependent variables measured in parents (e.g., child self-efficacy predicted parental support provision and, indirectly, parental MVPA); (c) across-individual indirect effects, accounting for self-efficacy and MVPA measured in children, combined with parental reports of social support.Conclusions: The findings provide support for both cultivation and enabling models in the context of MVPA among parent-child dyads.

This analysis (1) describes the prevalence and severity of psychiatric inpatient violence against nurses in Switzerland's German‐speaking region and (2) investigates the associations between nurse‐related characteristics (socio‐demographics; previous exposure to severe forms of psychiatric inpatient violence; attitude towards psychiatric inpatient violence) and nurses' exposure to various types of psychiatric inpatient violence. We used cross‐sectional survey data from the MatchRN Psychiatry study sample of 1128 nurses working on 115 units across 13 psychiatric hospitals. In addition to lifetime severe assaults, nurses' exposure to violence against property, verbal violence, verbal sexual violence, physical violence, and physical sexual violence was assessed for the 30 days prior to the survey. Descriptive statistics (frequency and percentage) were calculated for each class of violence as also for items under study. With generalized linear mixed models, odds ratios and 95% confidence intervals were calculated. Of nurse respondents, 73% reported facing verbal violence, 63% violence against property, 40% verbal sexual violence, 28% physical violence, and 14% physical sexual violence. Almost 30% had been subjected to a serious assault in their professional lifetimes. All nurse characteristics were associated with psychiatric inpatient violence against nurses, especially a history of sexual assault (OR 4.53, 95%‐CI 2.19–9.34; P = 0.00) and ≤3 years' professional experience (OR 3.70, 95%‐CI 1.95–7.02; P = 0.00). Prevalence data suggest that widely used strategies such as aggression management courses or alarm devices cannot fully reduce patient violence against nurses in psychiatry. This situation demands proactive strategies in safety and violence prevention. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the impact of vaginal microbiota on pregnancy outcomes in women undergoing assisted reproduction.Design: A prospective cohort study.Setting: A university-based assisted reproductive technology (ART) centre.Population: 223 women undergoing ART treatment.Methods: Prior to embryo transfer, vaginal samples were collected from the posterior fornix. Vaginal microbiota identification was carried out using next-generation sequencing and categorised according to the V3-V4 hypervariable region in the 16S rRNA gene region.Main Outcome Measures: ART clinical outcomes (implantation, clinical pregnancy rates and live birth rates).Results: The live birth rate in women with community state type (CST)-I (39%) was higher than that in women with CST-III (21.5%) but the difference was not statistically significant (P = 0.052). The relative abundance of Lactobacillus was lower in women who failed to become pregnant (NP group) (67.71%) than in women who became pregnant (PR group) (79.72%). However, this difference was not statistically significant (P = 0.06). In the NP group, the relative abundance of Streptococcus (7.81%) and Gardnerella (9.40%) was higher than that in the PR group (relative abundance of Streptococcus and Gardnerella was 2.28% and 5.56%, respectively). The abundance of Streptococcus was found to be statistically significantly different between the two study groups (P = 0.014). Linear discriminant analysis (LDA) further validated that Streptococcus had the highest contribution (LDA score >4.0) to the difference between these two groups.Conclusions: Streptococcus has the highest contribution to the distinction between the PR and NP groups.Tweetable Abstract: A relatively high abundance of Streptococcus in the vaginal microbiota may be associated with a lower ART success rate.

Background: M5717 is the first plasmodium translation elongation factor 2 inhibitor to reach clinical development as an antimalarial. We aimed to characterise the safety, pharmacokinetics, and antimalarial activity of M5717 in healthy volunteers.Methods: This first-in-human study was a two-part, single-centre clinical trial done in Brisbane, QLD, Australia. Part one was a double-blind, randomised, placebo-controlled, single ascending dose study in which participants were enrolled into one of nine dose cohorts (50, 100, 200, 400, 600, 1000, 1250, 1800, or 2100 mg) and randomly assigned (3:1) to M5717 or placebo. A sentinel dosing strategy was used for each dose cohort whereby two participants (one assigned to M5717 and one assigned to placebo) were initially randomised and dosed. Randomisation schedules were generated electronically by independent, unblinded statisticians. Part two was an open-label, non-randomised volunteer infection study using the Plasmodium falciparum induced blood-stage malaria model in which participants were enrolled into three dose cohorts. Healthy men and women of non-childbearing potential aged 18-55 years were eligible for inclusion; individuals in the volunteer infection study were required to be malaria naive. Safety and tolerability (primary outcome of the single ascending dose study and secondary outcome of the volunteer infection study) were assessed by frequency and severity of adverse events. The pharmacokinetic profile of M5717 was also characterised (primary outcome of the volunteer infection study and secondary outcome of the single ascending dose study). Parasite clearance kinetics (primary outcome of the volunteer infection study) were assessed by the parasite reduction ratio and the corresponding parasite clearance half-life; the incidence of recrudescence up to day 28 was determined (secondary outcome of the volunteer infection study). Recrudescent parasites were tested for genetic mutations (exploratory outcome). The trial is registered with ClinicalTrials.gov (NCT03261401).Findings: Between Aug 28, 2017, and June 14, 2019, 221 individuals were assessed for eligibility, of whom 66 men were enrolled in the single ascending dose study (eight per cohort for 50-1800 mg cohorts, randomised three M5717 to one placebo, and two in the 2100 mg cohort, randomised one M5717 to one placebo) and 22 men were enrolled in the volunteer infection study (six in the 150 mg cohort and eight each in the 400 mg and 800 mg cohorts). No adverse event was serious; all M5717-related adverse events were mild or moderate in severity and transient, with increased frequency observed at doses above 1250 mg. In the single ascending dose study, treatment-related adverse events occurred in three of 17 individuals in the placebo group; no individual in the 50 mg, 100 mg, or 200 mg groups; one of six individuals in each of the 400 mg, 1000 mg, and 1250 mg groups; two of six individuals in the 600 mg group; and in all individuals in the 1800 mg and 2100 mg groups. In the volunteer infection study, M5717-related adverse events occurred in no participants in the 150 mg or 800 mg groups and in one of eight participants in the 400 mg group. Transient oral hypoesthesia (in three participants) and blurred vision (in four participants) were observed in the 1800 mg or 2100 mg groups and constituted an unknown risk; thus, further dosing was suspended after dosing of the two sentinel individuals in the 2100 mg cohort. Maximum blood concentrations occurred 1-7 h after dosing, and a long half-life was observed (146-193 h at doses ≥200 mg). Parasite clearance occurred in all participants and was biphasic, characterised by initial slow clearance lasting 35-55 h (half-life 231·1 h [95% CI 40·9 to not reached] for 150 mg, 60·4 h [38·6 to 138·6] for 400 mg, and 24·7 h [20·4 to 31·3] for 800 mg), followed by rapid clearance (half-life 3·5 h [3·1 to 4·0] for 150 mg, 3·9 h [3·3 to 4·8] for 400 mg, and 5·5 h [4·8 to 6·4] for 800 mg). Recrudescence occurred in three (50%) of six individuals dosed with 150 mg and two (25%) of eight individuals dosed with 400 mg. Genetic mutations associated with resistance were detected in four cases of parasite recrudescence (two individuals dosed with 150 mg and two dosed with 400 mg).Interpretation: The safety, pharmacokinetics, and antimalarial activity of M5717 support its development as a component of a single-dose antimalarial combination therapy or for malaria prophylaxis.Funding: Wellcome Trust and the healthcare business of Merck KGaA, Darmstadt, Germany.

Background: Antimicrobial resistance is a major global health concern, driven by overuse of antibiotics. We aimed to assess the effectiveness of a national antimicrobial stewardship intervention, the National Health Service (NHS) England Quality Premium implemented in 2015-16, on broad-spectrum antibiotic prescribing and Escherichia coli bacteraemia resistance to broad-spectrum antibiotics in England.Methods: In this quasi-experimental, ecological, data linkage study, we used longitudinal data on bacteraemia for patients registered with a general practitioner in the English National Health Service and patients with E coli bacteraemia notified to the national mandatory surveillance programme between Jan 1, 2013, and Dec 31, 2018. We linked these data to data on antimicrobial susceptibility testing of E coli from Public Health England's Second-Generation Surveillance System. We did an ecological analysis using interrupted time-series analyses and generalised estimating equations to estimate the change in broad-spectrum antibiotics prescribing over time and the change in the proportion of E coli bacteraemia cases for which the causative bacteria were resistant to each antibiotic individually or to at least one of five broad-spectrum antibiotics (co-amoxiclav, ciprofloxacin, levofloxacin, moxifloxacin, ofloxacin), after implementation of the NHS England Quality Premium intervention in April, 2015.Findings: Before implementation of the Quality Premium, the rate of antibiotic prescribing for all five broad-spectrum antibiotics was increasing at rate of 0·2% per month (incidence rate ratio [IRR] 1·002 [95% CI 1·000-1·004], p=0·046). After implementation of the Quality Premium, an immediate reduction in total broad-spectrum antibiotic prescribing rate was observed (IRR 0·867 [95% CI 0·837-0·898], p<0·0001). This effect was sustained until the end of the study period; a 57% reduction in rate of antibiotic prescribing was observed compared with the counterfactual situation (ie, had the Quality Premium not been implemented). In the same period, the rate of resistance to at least one broad-spectrum antibiotic increased at rate of 0·1% per month (IRR 1·001 [95% CI 0·999-1·003], p=0·346). On implementation of the Quality Premium, an immediate reduction in resistance rate to at least one broad-spectrum antibiotic was observed (IRR 0·947 [95% CI 0·918-0·977], p=0·0007). Although this effect was also sustained until the end of the study period, with a 12·03% reduction in resistance rate compared with the counterfactual situation, the overall trend remained on an upward trajectory. On examination of the long-term effect following implementation of the Quality Premium, there was an increase in the number of isolates resistant to at least one of the five broad-spectrum antibiotics tested (IRR 1·002 [1·000-1·003]; p=0·047).Interpretation: Although interventions targeting antibiotic use can result in changes in resistance over a short period, they might be insufficient alone to curtail antimicrobial resistance.Funding: National Institute for Health Research, Economic and Social Research Council, Rosetrees Trust, and The Stoneygate Trust.

Background: Latent tuberculosis infection (LTBI) is one of the most prevalent infections globally and can lead to the development of active tuberculosis disease. In many low-burden countries, LTBI is concentrated within migrant populations often because of a higher disease burden in the migrant's country of origin. National programmes consequently focus on screening and treating LTBI in migrants to prevent future tuberculosis cases; however, how effective these programmes are is unclear. We aimed to assess LTBI treatment initiation and outcomes among migrants, and the factors that influence both.Methods: For this systematic review and meta-analysis, we searched Embase, MEDLINE, and Global Health, and manually searched grey literature from Jan 1, 2000, to April 21, 2020. We included primary research articles reporting on LTBI treatment initiation or completion, or both, in migrants and excluded articles in which data were not stratified by migrant status, or in which the data were related to outcomes before 2000. There were no geographical or language restrictions. All included studies were quality appraised using recognised tools depending on their design, and we assessed the heterogeneity of analyses using I2. We extracted data on the numbers of migrants initiating and completing treatment. Our primary outcomes were LTBI treatment initiation and completion in migrants (defined as foreign-born). We used random-effects meta-regression to examine the influence of factors related to these outcomes. The study is registered with PROSPERO (CRD42019140338).Findings: 2199 publications were retrieved screened, after which 39 publications from 13 mostly high-income, low-burden countries were included in our analyses, with treatment initiation and completion data reported for 31 598 migrants positive for LTBI, with not all articles reporting the full pathway from initiation to completion. The pooled estimate for the true proportion of migrants testing positive who initiated treatment was 69% (95% CI 51-84; I2= 99·62%; 4409 of 8764). The pooled estimate for the true proportion of migrants on treatment in datasets, who subsequently completed it was 74% (95% CI = 66-81; I2= 99·19%; 15 516 of 25 629). Where data were provided for the entire treatment pathway, the pooled estimate for the true proportion of migrants who initiated and completed treatment after a positive test was only 52% (95% CI 40-64; I2= 98·90%; 3289 of 6652). Meta-regression showed that LTBI programmes are improving, with more recent reported data (2010-20) associated with better rates of treatment initiation and completion, with multiple complex factors affecting treatment outcomes in migrants.Interpretation: Although our analysis highlights that LTBI treatment initiation and completion in migrants has improved considerably from 2010-20, there is still room for improvement, with drop out reported along the entire treatment pathway. The delivery of these screening and treatment programmes will require further strengthening if the targets to eradicate tuberculosis in low-incidence countries are to be met, with greater focus needed on engaging migrants more effectively in the clinic and understanding the diverse and unique barriers and facilitators to migrants initiating and completing treatment.Funding: European Society of Clinical Microbiology and Infectious Diseases, the Rosetrees Trust, the National Institute for Health Research, and the Academy of Medical Sciences.

Objective: Pediatric patients spend significant time on maintenance hemodialysis (HD) and traveling. They are often not capable of participating in sports activities. To assess the effects of exercise training during HD on dialysis efficacy in children and adolescents, we set up a multi-center randomized controlled trial (RCT). Methods: Patients on HD, age 6 to 18 years, were randomized either to 3× weekly bicycle ergometer training or to no training during HD for 12 weeks. Change in single-pool Kt/V (spKt/V) was the primary outcome parameter. Results: We randomized 54 patients of whom 45 qualified (23 in the intervention and 22 in the waiting control group, 14.5 ± 3.01 years, 32 male and 13 female) for the intention-to-treat (ITT) population. Only 26 patients finished study per-protocol (PP). Training was performed for an average of 11.96 weeks (0.14–13.14) at 2.08 ± 0.76 times per week and for a weekly mean of 55.52 ± 27.26 min. Single-pool Kt/V was similar in the intervention compared to the control group (1.70 [0.33] vs. 1.79 [0.55]) at V0 and (1.70 [0.36] vs. 1.71 [0.51]) at V1; secondary endpoints also showed no difference in both ITT and PP analysis. No significant adverse events were reported. No bleeding or needle dislocation occurred in 1670 training sessions. Conclusions: Intradialytic bicycle training is safe, but does not improve dialysis efficacy and physical fitness. However, the study can be considered underpowered, particularly because of high dropout rates. Future studies need better strategies to increase motivation and compliance and other more effective/intensive exercise measures should be evaluated. Trial registration: The trial was registered in ClinicalTrials.Gov (Clinicaltrials.gov identifier: NCT01561118) on March 22, 2012. [ABSTRACT FROM AUTHOR]

Background: This study investigated the individual and combined effects of self-reported resilience and serum ghrelin levels on 12-week remission in outpatients with depressive disorders who received antidepressant treatment.Methods: The Connor-Davidson Resilience Scale (CDRS) score and serum ghrelin levels were assessed at baseline in 1,094 patients. The patients initially received antidepressant monotherapy. Patients with an insufficient response or uncomfortable side effects received alternative treatments every 3 weeks (at 3, 6, and 9 weeks). Subsequently, 12-week remission, defined as a Hamilton Depression Rating Scale (HAMD) score of ≤ 7, was evaluated. The individual and combined effects of the CDRS score (low vs. high) and serum ghrelin level (low vs. high) on 12-week remission were analyzed using logistic regression models after adjusting for relevant covariates.Results: The individual effects of the CDRS score and serum ghrelin level on 12-week remission were not statistically significant. However, the high-CDRS, high-ghrelin group had a significantly higher 12-week remission rate compared to the low-CDRS, low-ghrelin group.Conclusions: The combination of the CDRS score and serum ghrelin level is useful for predicting 12-week remission in patients with depressive disorders receiving pharmacotherapy.

Background: Depression is highly heterogeneous in its clinical presentation. Those with attention deficit/hyperactivity disorder (ADHD) may be at risk of a more chronic and impairing depression compared to those with depression alone according to studies of young people. However, no studies to date have examined ADHD in recurrently depressed adults in mid-life.Method: In a sample of women in mid-life (n=148) taken from a UK based prospective cohort of adults with a history of recurrent depression, we investigated the prevalence of ADHD and the association of ADHD with clinical features of depression.Results: 12.8% of the recurrently depressed women had elevated ADHD symptoms and 3.4% met DSM-5 diagnostic criteria for ADHD. None of the women reported having a diagnosis of ADHD from a medical professional. ADHD symptoms were associated with earlier age of depression onset, higher depression associated impairment, a greater recurrence of depressive episodes and increased persistence of subthreshold depression symptoms over the study period, higher levels of irritability and increased risk of self-harm or suicide attempt. ADHD symptoms were associated with increased risk of hospitalisation and receiving non-first-line antidepressant medication.Limitations: ADHD was measured using a questionnaire measure. We focussed on mothers in a longitudinal study of recurrent depression, so the findings may not apply to males or other groups.Conclusions: Higher ADHD symptoms appear to index a worse clinical presentation for depression. Clinical implications include that in women with early onset, impairing and recurrent depression, the possibility of underlying ADHD masked by depression needs to be considered.

While religion and spirituality (R/S) have been linked to positive mental health outcomes, most studies have employed cross-sectional designs, which do not allow one to evaluate the utility of R/S in predicting these outcomes. To address this gap, this study analyzed data from a 7-year nationally representative, prospective cohort study of U.S. military veterans to examine the effects of R/S on the development of incident mental health outcomes in this population. Specifically, we examined the association between organizational religious activity (ORA), non-organizational religious activity (NORA), and intrinsic religiosity (IR), and the risk of incident PTSD, suicidal ideation (SI), and hazardous drinking (HD). Multivariable logistic regression analyses revealed that ORA predicted a lower incidence of PTSD and SI; NORA a greater risk of developing HD; and IR a lower risk of developing HD. These results suggest that religion and spirituality, assessed in a nationally representative sample of military veterans, predict risk of developing PTSD, SI, and HD, over and above sociodemographic factors and perceived social support. Clinical implications and strategies for incorporating R/S into mental health assessment and interventions in this population are discussed. [ABSTRACT FROM AUTHOR]

Background: Anxiety and irritability frequently co-occur in youth and are mediated by aberrant threat responses. However, empirical evidence on neural mechanisms underlying this co-occurrence is limited. To address this, we apply data-driven latent phenotyping to data from a prior report of a well-validated threat extinction recall fMRI paradigm.Methods: Participants included 59 youth (28 anxiety disorder, 31 healthy volunteers; Mage=13.15 yrs) drawn from a transdiagnostic sample of 331 youth, in which bifactor analysis was conducted to derive latent factors representing shared vs. unique variance of dimensionally-assessed anxiety and irritability. Participants underwent threat conditioning and extinction. Approximately three weeks later, during extinction recall fMRI, participants made threat-safety discriminations under two task conditions: current threat appraisal and explicit recall of threat contingencies. Linear mixed-effects analyses examined associations of a "negative affectivity" factor reflecting shared anxiety and irritability variance with whole-brain activation and task-dependent amygdala connectivity.Results: During recall of threat-safety contingencies, higher negative affectivity was associated with greater prefrontal (ventrolateral/ventromedial, dorsolateral, orbitofrontal), motor, temporal, parietal, and occipital activation. During threat appraisal, higher negative affectivity was associated with greater amygdala-inferior parietal lobule connectivity to threat/safety ambiguity.Limitations: Sample included only healthy youth and youth with anxiety disorders. Results may not generalize to other diagnoses for which anxiety and irritability are also common, and our negative affectivity factor should be interpreted as anxiety disorders with elevated irritability. Reliability of some subfactors was poor.Conclusions: Aberrant amygdala-prefrontal-parietal circuitry during extinction recall of threat-safety stimuli may be a mechanism underlying the co-occurrence of pediatric anxiety and irritability.

Background: To examine the association of job strain with cognitive ability and the influence of life-course job strain on later life cognitive decline.Methods: Data were derived from six waves of the Survey of Health, Aging, and Retirement in Europe. The study sample consists of 13349 participants aged 50 to 98 years at wave 2 and has been followed up for 12-years. Job strain status across working life was assessed using a short demand-control job strain model containing two core dimensions: job demands and job control collected in wave 3. Cognitive abilities concerning episodic memory was assessed by immediate recall and delayed recall tests, executive function was evaluated by verbal fluency test collected in all waves (waves 2-7) except wave 3. Mixed-effects model was used to estimate working life job strain and its cumulative effect on cognitive decline.Results: Both passive and high strain jobs were associated with lower levels of cognitive ability (episodic memory and verbal fluency) in comparison with active job. Long exposure to active- or low strain-job was associated with higher cognitive ability whereas long exposure to passive job or moderate duration of high strain job was associated with lower cognitive ability. The rate of memory decline was positively related to moderate duration of passive job and negatively related to long-term exposure to low strain job.Limitations: Information on working conditions was based on self-reported recollections.Conclusions: Working life variation in job strain status and their duration may explain individual differences in cognitive ability in later life.

Background: The literature suggests depressive symptoms differ in a non-linear fashion across adulthood and are more commonly reported in women as compared to men. Whether these trends are observed across countries in population-based cohorts is unclear.Methods: Cross-sectional observational study of approximately 138,000 women and men between the ages of 45 and 95 from three population-based cohorts representing Canadian, European, and American populations. Age, gender, educational attainment and annual income were assessed in each cohort. Depressive symptoms were assessed by the Center for Epidemiological Studies Depression Scale in the US and Canadian cohorts, and by the EURO-D in the European cohort.Results: Across all three cohorts, non-linear age trends and gender differences were observed in the report of depressive symptoms, independent from educational attainment and annual income effects. The non-linear age trends reflected a negative association between depressive symptoms and age during midlife and then a positive association in late life. Females reported greater depressive symptoms than males; however, an interaction between gender and age was also observed in the Canadian and European cohorts. Among Canadians, the gender differences were largest after age 70, whereas among Europeans, gender differences where largest among those approximately aged 60.Limitations: Limitations include: 1) the cross-sectional nature of the study, resulting in age differences potentially reflecting cohort effects rather than a developmental process; and 2) the use of different depressive symptoms measures across cohorts.Conclusions: Characterization of depressive symptoms over mid and late adulthood in women and men provides insights into potential focal points for intervention and allocation of resources.

Background: Previous research on the relationship between children's depressive and externalising symptoms, experience of school, and academic attainment is inconclusive. The aims of this study were (i) to test bidirectional associations between children's school experience and depressive and externalising symptoms at age 10-11 and 13-14, (ii) to ascertain whether school experience age 13-14 is associated with academic attainment age 16, and (iii) to test whether school experience mediates the relationship between depressive or externalising symptoms and attainment.Methods: Data was used from the Avon Longitudinal Study of Parents and Children (n=6,409). A cross-lagged model was used to investigate bidirectional associations between school experience (enjoyment and connectedness) and depression and externalising at age 10-11 and 13-14. The same framework was used to test if school experience aged 13-14 mediated associations of depressive and externalising symptoms with later attainment.Results: Depressive and externalising symptoms at 10-11 were negatively associated with school connectedness (depressive: standardised β=-0.06, CI: -0.11, 0.01; externalizing: β=-0.13, CI: -0.17, -0.08), and school enjoyment at 13-14 (depressive β=-0.04, -0.08, 0.03; externalising: β=-0.08, CI: -0.13, -0.03). School enjoyment at 13-14 was positively associated with attainment at 16 (β=0.10, CI: 0.04, 0.15), and partially mediated associations between depressive and externalising symptoms at 10-11 and attainment at 16 (depressive: proportion mediated 2.2%, CI: -1.5, 5.9; externalising: proportion mediated; 4.7%, CI: 0.7, 10.1,).Limitations: Results may be subject to residual confounding.Conclusions: School enjoyment is a potentially modifiable risk factor that may affect educational attainment of adolescents with depressive or externalising symptoms.

Background: There is limited research examining the natural trajectories of depression and anxiety, how these trajectories relate to baseline neural circuit function, and how symptom trajectory-circuit relationships are impacted by engagement in lifestyle activities including exercise, hobbies, and social interactions. To address these gaps, we assessed these relations over three months in untreated participants.Methods: 262 adults (59.5% female, mean age 35) with symptoms of anxiety and depression, untreated with pharmacotherapy or behavioral therapy, completed the DASS-42, WHOQOL, and custom surveys at baseline and follow-up to assess symptoms, psychosocial function, and lifestyle activity engagement. At baseline, participants underwent fMRI under task-free and task-evoked conditions. We quantified six circuits implicated in these symptoms: default mode, salience, negative and positive affect, attention, and cognitive control.Results: From baseline to 3 months, some participants demonstrated a natural improvement in anxiety (24%) and depression (26%) symptoms. Greater baseline salience circuit connectivity (pFDR=0.045), specifically between the left and right insula (pFDR=0.045), and greater negative affect circuit connectivity elicited by sad faces (pFDR=0.030) were associated with anxiety symptom improvement. While engagement in lifestyle activities were not associated with anxiety improvements, engagement in hobbies moderated the association between negative affect circuit connectivity and anxiety symptom improvement (p = 0.048).Limitations: The observational design limits causal inference.Conclusions: Our findings highlight the role of the salience and negative affect circuits as potential circuit markers of natural anxiety symptom improvements over time. Future studies that identify biomarkers associated with symptom improvements are critical for the development of personalized treatment targets. [ABSTRACT FROM AUTHOR]

Background: Rhythms And You (RAY) is an online intervention for bipolar disorders (BD) based on Interpersonal and Social Rhythm Therapy. We examined RAY's feasibility and acceptability for individuals with BD recruited from primary care. Because online interventions may be more effective when paired with human support, we evaluated RAY with and without weekly brief (∼5 min) calls from clinical helpers (CH).Methods: Participants (n = 47) meeting criteria for BD I, II or other specified BD, presenting for primary care, were randomly assigned to RAY, RAY-CH, or Adjunctive Reading Material (ARM) control. RAY consisted of 12 weekly online modules. ARM consisted of 12 weekly emails. Participants were assessed at baseline, 4, 8, and 12 weeks.Results: RAY showed high completion rates and Client Satisfaction Questionnaire scores (36/47, 77% and 25.1 ± 5.5, respectively; no group differences). Effect sizes for RAY- CH ranged from small [Internal State Scale-Activation Subscale (ISS-ACT); d = 0.3] to large [SF-12 Mental Health Composite Score (SF-12 MHC); d = 1.3]. ARM also showed moderate effects (ISS-ACT d = 0.7; Quick Inventory of Depressive Symptoms, d = 0.8). SF-12 MHC scores showed a time*group interaction (F = 2.38, df = 6,32, p = 0.05) favoring RAY-CH. Number of logins trended toward significant association with improved social rhythm regularity (F = 4.09, df = 1, 17, p = 0.06).Limitations: Sample size is small, limiting conclusions that can be drawn.Conclusions: Remote delivery of RAY for individuals with BD is feasible and acceptable. More time spent engaged in RAY was associated with greater improvement in social rhythm regularity. Preliminary evidence suggests adding brief human support to RAY may yield better outcomes.
