Objective: To assess the psychological impact of the COVID-19 crisis on the police and armed forces. Methods: Participants (N = 242) completed an online survey that assessed posttraumatic stress symptoms (PTSS), burnout, emotional suppression, and labor and sociodemographic variables. Mean difference, correlation, and stepwise linear regression tests were performed. Results: One-third of participants showed severe PTSS, linked to patrolling duties, very frequent contact with other people, fear of contagion, perceived pandemic severity, living with at-risk people, taking a COVID-19 test, working more than normal, suffering an assault, having little vacation, and having to distance from loved ones. PTSS also correlated with the burnout dimensions and emotional suppression. Three-quarters had not received any support from their workplace. Conclusions: Effective interventions to optimize these professionals' personal, social, and working conditions are needed. [ABSTRACT FROM AUTHOR]

Background: During the COVID-19 pandemic, nurses have faced innumerable challenges, which have contributed to staggering increases in burnout rates. In the health care arena, burnout has been associated with the onset or exacerbation of physical illness, neglect of self-care, fatigue, decreased patient satisfaction, higher medication error rates, lack of nurse engagement, and increased nurse turnover. Purpose: This cross-sectional study sought to determine whether a correlation exists between self-reported physical activity and nurses' perception of burnout in a sample of hospital RNs. The secondary aim was to determine whether a correlation exists between the level of perceived burnout and the number of medication errors or near misses. Methods: Participants were asked to provide demographic information, complete the Copenhagen Burnout Inventory (CBI) and the Godin Leisure-Time Exercise Questionnaire (GLTEQ), and self-report the number of medication errors or near misses they were involved in during the previous 12 months. Data were analyzed using Stata version 17 software. Results: A total of 216 participants returned usable surveys. Regarding the relationship between burnout and physical activity levels, data analysis was performed for the 210 participants who completed both the CBI and the GLTEQ. Compared with the least physically active nurses, the most active nurses had significantly lower CBI scores, with 68.5% of those reporting low or no burnout also scoring 24 or more on the GLTEQ. The least physically active nurses had significantly higher CBI scores, with 47.6% of those reporting high burnout also scoring 13 or less on the GLTEQ. Moreover, 90% of the nurses with high burnout levels had directly cared for COVID-19 patients at some point between 2020 and 2022. Medical–surgical nurses experienced significantly higher levels of burnout compared with nurses working in other service areas. No significant relationship was found between the number of medication errors or near misses and burnout levels. Conclusions: This study found that the most physically active nurses reported lower levels of burnout, while the highest levels of burnout were found in the least active nurses. Although COVID-19 infection rates have eased, many nurses, particularly those who have cared for COVID-19 patients and those who work in medical–surgical environments, continue to experience burnout. Targeted programs to reduce work-related burnout, as well as organizational sponsorship of and unit-level support for such programs, are urgently needed. This study's findings suggest that promotion of physical activity may be an essential component to alleviating burnout. This cross-sectional study sought to determine whether a correlation exists between self-reported physical activity levels and nurses' perception of burnout in a sample of hospital RNs.

Introduction: The aim of this study was to investigate 12 wk of simple and complex voluntary wheel running on Alzheimer's disease (AD), associated biomarkers, and behaviors. Methods: Sixty male Wistar rats were randomly divided into six groups: healthy control (Con-Sed), AD only (AD-Sed), simple wheel control (SWC), complex wheel control (CWC), simple wheel AD (SWAD), and complex wheel AD (CWAD). Novelty-suppressed feeding test and the Morris water maze test were used to evaluate depression and memory, respectively. Ki67 was measured in the hippocampus, whereas interleukin (IL)-1β and neural/glial antigen 2 (NG2) were measured in both the hippocampus and the prefrontal cortex. One-way ANOVA with Tukey's post hoc test was performed. Results: AD-Sed group had significantly lower special memory (P < 0.001) compared with Con-Sed. Simple and complex wheel running attenuated these deficits in the SWAD and CWAD groups, respectively (P < 0.001). Only the CWAD group had significantly improved novelty-suppressed feeding test time compared with AD-Sed (P < 0.001), equivalent to the healthy wheel running groups. AD-Sed has significantly higher hippocampal concentrations of Ki67 (P = 0.01) compared with the Con-Sed. Both SWAD and CWAD had significantly reduced Ki67 with similar concentrations compared with the SWC and CWC groups (P > 0.05). AD-Sed animals also presented with significantly higher hippocampal and prefrontal cortex concentrations of IL-1β compared with Con-Sed (P < 0.001). SWAD and CWAD had no effect in changing these concentrations. Complex wheel running significantly increased NG2 in the healthy control and AD models, whereas simple wheel running significantly increased NG2 in the AD model. Conclusions: The results of our study suggest that complex wheel running might be more advantageous in promoting memory and neuroplasticity while reducing depression that is associated with AD.

Women perform exercise in sports bras to limit breast motion. However, as the breasts become restricted, respiratory function may become compromised. Purpose: We set out to understand how underband tightness or pressure of a sports bra relates to respiratory function and the mechanical work of breathing (...B) during exercise. Our secondary purpose was to quantify the effects of underband pressure on ...O2 during submaximal running. Methods: Nine highly trained female runners with normal pulmonary function completed maximal and submaximal running in three levels of underband restriction: loose, self-selected, and tight. Results: During maximal exercise, we observed a significantly greater ...B during the tight condition (350 ± 78 J⋅min-1) compared with the loose condition (301 ± 78 J⋅min-1; P < 0.05), and a 5% increase in minute ventilation (...E) during the tight condition compared with the loose condition (P < 0.05). The pattern of breathing also differed between the two conditions; the greater maximal ...E during the tight condition was achieved by a higher breathing frequency (57 ± 6 vs. 52 ± 7 breaths⋅min-1; P < 0.05), despite tidal volume being significantly lower in the tight condition compared with the loose condition (1.97 ± 0.20 vs. 2.05 ± 0.23 L; P < 0.05). During steady-state submaximal running, ...O2 increased 1.3 ± 1.1% (range: -0.3 to 3.2%, P < 0.05) in the tight condition compared with the loose condition. Conclusions: Respiratory function may become compromised by the pressure exerted by the underband of a sports bra when women self-select their bra size. In the current study, loosening the underband pressure resulted in a decreased work of breathing, changed the ventilatory breathing pattern to deeper, less frequent breaths, and decreased submaximal oxygen uptake (improved running economy). Our findings suggest sports bra underbands can impair breathing mechanics during exercise and influence whole-body metabolic rate. [ABSTRACT FROM AUTHOR]

Purpose: Muscle mechanics is paramount in our understanding of motor performance. However, little is known regarding the sensitivity of fascicle dynamics and connective tissues stiffness to exercise duration and ambient temperature during running, both increasing muscle temperature. This study aimed to determine gastrocnemius medialis (GM) fascicle dynamics in vivo during running in temperate and hot conditions, as well as muscle-tendon unit responses. Methods: Using ultrafast ultrasound, 15 participants (8 men, 7 women; 26 ± 3 yr) were tested before, during (2 and 40 min), and after a running task (40 min at 10 km⋅h-1) in temperate (TEMP; ~23°C) and hot (HOT: ~38°C) conditions. Results: Although core, skin temperatures, and heart rate increased from the beginning to the end of the exercise and in a larger extent in HOT than TEMP (P < 0.001), the physiological stress elicited did not alter running temporal parameters and GM fascicle operating lengths, with similar behavior of the fascicles on their force-length relationship, over time (2 vs 40 min) or across condition (TEMP vs HOT; P ≥ 0.248). Maximal voluntary force production did not reported statistical changes after exercise (P = 0.060), and the connective tissues stiffness measured (i.e., passive muscle and stiffness of the series-elastic elements) did not show neither time (P ≥ 0.281), condition (P ≥ 0.256) nor time-condition interaction (P ≥ 0.465) effect. Conclusions: This study revealed that prolonged running exercise does not alter muscle-tendon unit properties and interplay, which are not influenced by ambient temperature. These findings may rule out potential detrimental effects of heat on muscle properties and encourage further investigations on longer and more intense running exercise. [ABSTRACT FROM AUTHOR]

Introduction/Purpose: There is a well-established association between preexisting depression/anxiety and greater postconcussion symptom burden, but the potential impact of antidepressant medications has not been fully explored. The primary objective of this study was to compare preinjury/baseline and postinjury concussion symptomscores and neurocognitive performance of athletes on antidepressant medications, both with healthy controls and with those with depression/anxiety not on antidepressants. Methods: This is a cross-sectional study using data collected from 49,270 junior and high school athletes from computerized neurocognitive assessments (Immediate Post-Concussion Assessment and Cognitive Test [ImPACT]) administered between 2009 and 2018 held by the Massachusetts Concussion Management Coalition. The main outcome measures were symptom scores and neurocognitive performance measures, all of which were assessed both at baseline and postinjury. Statistical analysis included analysis of variance and Tukey pairwise comparisons for continuous variables and Fisher's exact test for categorical variables. Multivariate regression models were used to adjust for potential confounding variables. Results: Both at baseline and postinjury, athletes with depression/anxiety had mean total symptom scores that were more than double that of healthy controls regardless of antidepressant use. Although there were no significant differences in neurocognitive performance at baseline, depression/anxiety was associated with small but significant decreases in postinjury visual memory and visual motor scores. Conclusions: Both at baseline and after sustaining a concussion, young athletes with depression/anxiety experience significantly greater symptom burden compared with healthy controls regardless of antidepressant use.

Background: There is an increasing demand for comprehensive geriatric care. Nurse practitioners (NPs), who undergo specialized training, are situated to provide such care. In Israel, the role of a geriatric nurse practitioner was introduced in the health care system 10 years ago. However, little is known about the rate of professional satisfaction and realization of full potential among these nurses. Purpose: The aims of this study are (1) to describe the geriatric NP workforce in Israel, (2) to measure the current geriatric scope of practice, and (3) to measure the geriatric NP satisfaction from their working environment. Methodology: For this cross-sectional study, a survey, comprising three sections relating to demographics, professional qualifications and scope of practice, and career satisfaction, was sent to 53 geriatric nurse practitioners in Israel who currently work as geriatric nurse practitioners. Results: Forty-seven nurses participated in the survey. Almost 64% reported that they are satisfied with their position, and 72% reported that they are able to fulfill their full scope of practice. The mean score for scope of practice was 68.31 out of a possible score of 100. Conclusions: A number of qualifications were correlated with satisfaction at work, indicating that nurses tend to be more satisfied at work when they are able to fulfill their potential. Implications: Ensuring nurse practitioners' ability to realize their full potential should be a goal of the health care system. Interventions should be in place to encourage nurses to perform tasks related to their work, for which they are trained. [ABSTRACT FROM AUTHOR]

Background: Self-efficacy is an important factor associated with healthy lifestyle changes in heart failure treatment. Functional capacity testing of heart failure patients (HFPs) can stratify prognosis. Reduced functional capacities in HFPs are linked to a poor heart failure prognosis. Limited research has examined the potential relationship between self-efficacy and functional capacity. Aim: The aims of this study were to assess self-efficacy level and functional capacity among HFPs after hospitalization, and examine whether there is a relationship between them. Methods: A descriptive correlational design was used. A convenience sample of 220 HFPs was recruited from 2 hospitals in Jordan. The Arabic version of Cardiac Self-Efficacy Questionnaire was used to assess self-efficacy, the 6-Minute Walking Test (6-MWT) was used to assess functional capacity, and the Borg rating of perceived exertion scale (Borg Scale) was used to assess exertion during 6-MWT. Result: The sample included 46.8% male (n = 103) and 53.2% female (n = 117). The mean age was 52.66 ± 8.91 years. Most of the HFPswere categorized based on New York Heart Association classification as class I, 35.9% (n = 79), and class II, 41.4% (n = 91). The mean ejection fraction was 41.46 ± 9.44. The global self-efficacy was moderate (32.98 ± 9.92), and the mean score for the 6-MWT was 494.35 ± 143. 37. The Borg Scale mean was 10.94 ± 3.34. In addition, there was a positive relationship between self-efficacy and 6-MWT (r = 0.63, n = 220, P = .01). Conclusion: This study provides baseline data for further research on treatment of HFPs, and the development of evidence-based tailored health interventions to maintain and improve self-efficacy and functional capacity among these service users. Moreover, replicated researches can test the study results considering different methodologies, such as using objective functional capacity tool and longer follow-up periods. [ABSTRACT FROM AUTHOR]

Patients who have Parkinson disease require individualized medication regimens to optimize care. A review of the medication management of patients admitted to a tertiary care hospital with a secondary diagnosis of Parkinson disease found significant departures from the patients' home regimen. Medication regimens are often altered by health care teams unfamiliar with Parkinson disease–specific care in order to conform to standard hospital medication orders and administration times, potentially resulting in increased patient falls, delirium, and mortality. A nurse-led multidisciplinary team consisting of pharmacy, nursing, informatics, neurology, and quality personnel implemented a quality improvement (QI) project between July 2020 and July 2022 to identify patients with Parkinson disease, including those with a secondary diagnosis and those undergoing deep brain stimulation, and customize medication management in order to reduce length of stay, mortality, falls, falls with harm, and 30-day readmissions. The QI project team also evaluated patient satisfaction with medication management. Among patients with a secondary diagnosis of Parkinson disease, the proportion who had medication histories conducted by a pharmacy staff member increased from a baseline of 53% to more than 75% per month. For all patients with Parkinson disease, those whose medication history was taken by a pharmacy staff member had orders matching their home regimen 89% of the time, whereas those who did not had orders matching the home regimen only 40% of the time. Among patients with a secondary diagnosis of Parkinson disease, the length-of-stay index decreased from a baseline of 1 to 0.94 and observed-to-expected mortality decreased from 1.03 to 0.78. The proportion of patients experiencing a fall decreased from an average of 5% to 4.08% per quarter, while the proportion of patients experiencing a fall with harm decreased from an average of 1% to 0.75% per quarter. The rate of 30-day readmissions decreased from 10.81% to 4.53% per quarter. Patient satisfaction scores were 1.95 points higher for patients who had medication histories taken by pharmacy than for those who did not (5 versus 3.05). How a nurse-led multidisciplinary team implemented a quality improvement project to identify patients with Parkinson disease and customize medication management in order to reduce length of stay, mortality, falls, falls with harm, and 30-day readmissions.

Purpose: Sedentary behavior may contribute to increased central wave reflection due to associated peripheral vasoconstriction, yet its impact on central hemodynamics and the mitigating effects of interventional strategies have not been thoroughly investigated. We tested whether standing or seated elliptical breaks alleviate the deleterious effects of prolonged sitting on central wave reflections. Methods: Eighteen healthy adults (9 9 females, 25 ± 3 yr) completed three 3-h protocols on separate days: uninterrupted sitting, sitting with periodic standing, and sitting with periodic seated elliptical activity. Central wave reflection, central pulse wave velocity, and lower-limb pulse wave velocity were measured before and after each intervention. Results: Central relative wave reflection magnitude (RM) increased during sitting (0.31 ± 0.05 to 0.35 ± 0.05; P <0.01) but did not change after standing (0.30 ± 0.05 to 0.32 ± 0.04; P = 0.19) or elliptical protocols (0.30 ± 0.05 to 0.30 ± 0.04; P > 0.99). The change in RM during prolonged sitting (ARM) was attenuated with elliptical activity (0.04 ± 0.05 vs 0.00 ± 0.03; P = 0.02) but not with periodic standing (0.04 ± 0.04 vs 0.02 ± 0.05; P = 0.54). In addition, augmentation index and central pulse wave velocity increased after sitting (both P < 0.01) and periodic standing (both P < 0.01) but were unchanged after elliptical activity. Lower limb pulse wave velocity did not change after sitting (P = 0.73) or standing (P = 0.21) but did decrease after elliptical activity (P = 0.03). Conclusions: Prolonged sitting without interruptions increased central wave reflection, whereas elliptical but not standing interruptions were able to ameliorate multiple sitting-induced vascular consequences. More work is required to examine the long-term effectiveness of interruption strategies, as well as the optimal type, frequency, and duration for reducing vascular risk associated with sedentary behaviors.

Purpose: Neuromuscular deficits and atrophy after anterior cruciate ligament reconstruction (ACLR) may be accompanied by changes in muscle composition and poor quadriceps muscle quality (QMQ). Quadriceps atrophy occurs after ACLR but improves within the first three postoperative months, yet this hypertrophy could be attributable to increases in noncontractile tissue (i.e., poor QMQ). The purposes of this study were to evaluate changes in QMQ after ACLR and to determine if changes in QMQ and cross-sectional area (CSA) occur in parallel or independently. Methods: A longitudinal prospective cohort design was implemented to evaluate QMQ and CSA in 20 individuals with ACLR and 12 healthy controls. Participants completed three testing sessions (baseline/presurgery, 1 month, and 3 months) during which ultrasound images were obtained from the vastus lateralis (VL) and rectus femoris (RF). QMQ was calculated as the echo intensity (EI) of each image, with high EI representing poorer QMQ. Anatomical CSA was also obtained from each image. Results: RF and VL EI were greater at 1 and 3 months in the ACLR limb compared with baseline and the contralateral limb and did not change between 1 and 3 months. VL and RF CSA in the ACLR limb were smaller at 1 and 3 months compared with the contralateral limb and controls (VL only) but increased from 1 to 3 months. Changes in QMQ and CSA were not correlated. Conclusions: QMQ declines within the first month after ACLR and does not improve by 3 months although hypertrophy occurs, suggesting that these morphological characteristics change independently after ACLR. Poorer QMQ represents greater concentration of noncontractile tissues within the muscle and potentially contributes to chronic quadriceps dysfunction observed after ACLR. [ABSTRACT FROM AUTHOR]

Introduction: The aim of the study was to compare maximal force, force steadiness, and the discharge characteristics of motor units in the tibialis anterior (TA) muscle during submaximal isometric contractions for ankle dorsiflexion and adduction of the foot. Methods: Nineteen active young adults performed maximal and submaximal isometric dorsiflexion and adduction contractions at five target forces (5%, 10%, 20%, 40%, and 60% maximal voluntary contraction [MVC]). The activity of motor units in TA was recorded by high-density EMG. Results: The maximal force was similar between dorsiflexion and adduction, despite EMG amplitude for TA being greater (P < 0.05) during dorsiflexion than adduction. The coefficient of variation (CV) for force (force steadiness) during dorsiflexion was always less (P < 0.05) than during adduction, except of 5% MVC force. No differences were observed for mean discharge rate; however, the regression between the changes in discharge rate relative to the change of force was significant for dorsiflexion (R² = 0.25, P < 0.05) but not for adduction. Discharge variability, however, was usually less during dorsiflexion. The CV for interspike interval was less (P < 0.05) at 10%, 20%, and 40% MVC but greater at 60% MVC during dorsiflexion than adduction. Similarly, the SD values of the filtered cumulative spike train of the motor units in TA were less (P < 0.05) at 5%, 10%, 20%, and 40% MVC during dorsiflexion than adduction. Conclusions: Although the mean discharge rate of motor units in TA was similar during foot adduction and ankle dorsiflexion, discharge variability was less during dorsiflexion resulting in less accurate performance of the steady adduction contractions. The neural drive to bifunctional muscles differs during their accessory function, which must be considered for training and rehabilitation interventions. [ABSTRACT FROM AUTHOR]

Physical medicine and rehabilitation physicians often care for disabled patients, who comprise America's largest marginalized population. Despitemedical students' and physicians' discomfort with caring for disabled patients and the pervasiveness of ableism in health care, medical education lacks disability-focused education. Kern's approach to curriculum development and disability community input were used to design a three-part, elective curriculum for first-year medical students. Part one introduced disability models and language. Part two described how to perform a comprehensive history and physical examination for a disabled patient using ADEPT-CARE. Part three provided an overview of disability history and the disability rights movement. The curriculum's goal was to improve students' attitudes regarding disability health and self-perceived knowledge and confidence in caring for patients with disabilities. The curriculum was evaluated through presurvey and postsurvey. Students favorably reviewed the curriculum. One hundred percent of students (n = 21) agreed or strongly agreed that the curriculum improved their knowledge of disability health, increased their perceived confidence in caring for patients with disabilities, and enhanced their medical education. There were no statistically significant differences in students' attitudes toward patients with disabilities after curriculum completion. Our asynchronous module provides one potential curriculum for increasing preclinical medical students' self-perceived knowledge of disability health. [ABSTRACT FROM AUTHOR]

Welwalk is a one-leg robotic-assisted gait system for stroke hemiplegic patients. This study examined the feasibility and efficacy of gait training using Welwalk (Welwalk training) for hemiplegic patients in the early phase after stroke onset, via cooperation between acute care and rehabilitation hospitals. Seven acute stroke patients (mean number of days fromonset = 7.9) with severe lower extremity paralysis participated. Patients underwent Welwalk training for 40 min/d, 5 d/wk in an acute care hospital, then 7 d/wk in a rehabilitation hospital with a seamless transition. Functional IndependenceMeasure scores for walking were assessed weekly. The endpoint was reaching Functional Independence Measurewalk score of 5 (supervision level). The primary outcomewas improvement efficiency of Functional IndependenceMeasure walk, which was the increase in Functional IndependenceMeasure walk score divided by the number of weeks required. Functional Independence Measure walk score for all patients improved from 1.1 to 5 (P = 0.01, r = 0.96). The mean number of weeks to achieve Functional Independence Measure walk score of 5 was 5 wks, and the improvement efficiency of Functional Independence Measure walk had a mean value of 0.9. No adverse events were reported duringWelwalk training. Hemiparetic patients' gait independence may be safely and rapidly improved by startingWelwalk training in the early phase after stroke onset.

Objective: The aim of the study is to verify the performance trajectory related to age, classification (KL: kayak level; M: male; F: female), and sex of elite kayak Para canoe athletes. Design: This is a retrospective cohort study. Results: Race results and athletes' data were retrieved from publicly available online databases for 17 competitions and 102 finals between 2015 and 2022. Race time reduced over the years except for KL3-M class. There was a reduction in the relative difference between KL2-M and KL3-M over the years (r = -0.83, 95% confidence interval = -0.34 to -0.97, P = 0.05). In addition, no significant differences were found in race times relative differences between KL2-F and KL3-F over the years. Although the correlation between age and performance was only found to be statistically significant in the KL3-F class, the ages of all classes (35.2, 32.6, 29.5, 34.6, 37.6, and 30.6 yrs for males and females KL1, KL2, and KL3, respectively) were higher than those in Olympic canoeing (27.8 yrs). Conclusions: Race times have improved overall since 2015, but not for the KL3-M class. Nevertheless, because of the stochastic ages of the finalist athletes, it was not possible to determine the age at which peak performance is achieved in all classes. Kayak Para canoe classes should be monitored in the coming years to determine whether interventions are necessary to improve differentiation. [ABSTRACT FROM AUTHOR]

Objective: The aim of the study is to evaluate the acute responses, in the in-hospital setting, of intensive elastic resistance training on physical function, pain, psychosocial variables, and inflammatory markers in patients undergoing total knee arthroplasty. Design: In a randomized controlled trial, 40 patients with total knee arthroplasty (=55 yrs) were assigned to either (1) the intervention group (elastic resistance strengthening) or (2) a control group (conventional protocol). Patients performed three sessions in the hospital at 24, 48, and 72 hrs after total knee arthroplasty. Outcome measures included: self-administered physical function, pain intensity, kinesiophobia, catastrophizing, self-efficacy, range of motion, perceived change, test timed up and go, knee joint effusion, isometric strength, pressure pain thresholds, and inflammatory markers (levels of procalcitonin and C-reactive protein). Results: The mixed analysis of variance model showed a significant group*time interaction in favor of the intervention group with a large effect size for kinesiophobia (ηp2 = 0.308, P < 0.001), catastrophizing (ηp2 = 0.242, P < 0.001), and passive range of motion flexion (ηp2 = 0.167, P < 0.001) and a moderate effect size for physical function (ηp2 = 0.103, P = 0.004), pain intensity (ηp2 = 0.139, P < 0.001), timed up and go (ηp2 = 0.132, P = 0.001), self-efficacy (ηp2 = 0.074, P = 0.016), active range of motion flexion (ηp2 = 0.121, P = 0.002), levels of procalcitonin (ηp2 = 0.099, P = 0.005), and C-reactive protein (ηp2 = 0.106, P = 0.004). Conclusions: Three sessions of intensive elastic resistance training improve physical function, perceived pain, psychosocial variables, and inflammatory markers during the hospitalization period after total knee arthroplasty.

BACKGROUND: Roux-en-Y gastric bypass (RYGB) demonstrates high rates of type 2 diabetes mellitus (T2DM) remission, a phenomenon hypothesized to be mediated mainly by weight loss. Compared with procedures that do not bypass the proximal small intestines, such as sleeve gastrectomy (SG), RYGB exhibits weight loss-independent intestinal mechanisms conducive to T2DM remission. We investigated continued diabetes remission (CDR) rates despite weight recurrence (WR) after RYGB compared with an SG cohort. STUDY DESIGN: A retrospective review of patients who underwent successful primary RYGB or SG with a BMI value of 35 kg/m² or more and a preoperative diagnosis of T2DM was performed. Patients with less than 5 years of follow-up, absence of WR, or lack of T2DM remission at nadir weight were excluded. After selecting the optimal procedure for glycemic control, rates of CDR were then stratified into WR quartiles and compared. RESULTS: A total of 224 RYGB and 46 SG patients were analyzed. The overall rate of CDR was significantly higher in the RYGB group (75%) compared with the SG group (34.8%; p < 0.001). The odds of T2DM recurrence were 5.5 times higher after SG compared with RYGB. Rates of CDR were stratified into WR quartiles (85.5%, <25%; 81.7%, 25% to 44.9%; 63.2%, 45% to 74.9%; and 60%, >75%). Baseline insulin use, higher preoperative glycosylated hemoglobin, and longer preoperative duration of T2DM were associated with T2DM recurrence, whereas WR was not. CONCLUSIONS: T2DM remission rates after RYGB are maintained despite WR, arguing for a concurrent weight loss-independent metabolic benefit likely facilitated by bypassing the proximal small intestine.

Background: In China, there are large differences between regions in the use of gastroscopies and public awareness of upper gastrointestinal (UGI) screening. Objective: This study investigated the current context and analyzed the barriers that influence UGI screening behavior among the general population in UGI cancer high-prevalence areas. Methods: A total of 320 participants anonymously answered an online questionnaire. The rank sum test was used to analyze the difference in the scores of the UGI screening awareness questionnaire among participants with different socio-demographic characteristics. Using the awareness level of UGI screening and gastroscopy as the dependent variable, and the socio-demographic characteristics as the independent variable, simple linear regression and binary logistic regression analysis were used to determine the factors influencing attitudes toward gastroscopy screening. We used Spearman's correlation analysis to examine the correlation between UGI screening awareness level and willingness to undergo a gastroscopy. Results: There was a correlation between the willingness to undergo gastroscopy and the awareness level of UGI screening (r = 0.243, p < 0.001). Linear regression analysis found that age, type of residence, education level, employment status, monthly income, history of gastroscopy, dietary habits, physical exercise, and convenience in obtaining information were significantly correlated with the awareness level of UGI screening (p < 0.05). Binary logistic regression analysis found that factors significantly associated with gastric cancer screening behavior include residence, monthly income, and self-perceived health status (p  < 0.05). Conclusion: It is necessary to improve education about UGI cancer and screening knowledge, with a focus on populations with lower education and income. [ABSTRACT FROM AUTHOR]

Continuing education (CE) activities may affect clinicians' knowledge, skills, self-efficacy, and/or performance. Studies have suggested that self-efficacy may moderate or mediate the relationship between knowledge/competence and performance. Some results have shown that increases in knowledge/competence contributed to increases in self-efficacy. However, clinicians do not always learn something "new" when they participate in CE activities; rather, their knowledge or skills may be reinforced. This study examined whether self-efficacy was greater when clinicians reinforced what they already knew compared with when they learned something new. Hierarchical linear modeling was conducted to examine the moderating role of status of knowledge/competence post-CE (reinforced/improved) in the relationship between post-CE knowledge/competence score and self-efficacy across 153 online continuing medical education- and/or CE-certified activities. The hierarchical linear modeling showed that learners with higher post-CE scores have higher post–self-efficacy ratings. Reinforced learners had higher post-CE–self-efficacy ratings than improved learners, controlling for post-CE score. This study contributes to an expanded understanding of the path from CE to practice. There was benefit to self-efficacy for learners who reinforced but did not improve their knowledge/competence. This study also suggests that pre-post questions can be considered part of the learning process. [ABSTRACT FROM AUTHOR]

This study aimed to conduct a comprehensive reviewof the top 50 most influential articles on stroke rehabilitation to investigate characteristics, such as the number of citations, year of publication, study design, and research topic, as well as to assess the evidence level and methodological quality. Moreover, we performed a supplementary assessment of the top 10 articles published within the past 5 yrs in the same domain, aiming to discern potential shifts in trends and methodological quality. Web of Science was used to search for articles on stroke rehabilitation. The data extracted from the articles included title, journal impact factor, year of publication, total number of citations, article topic, study design, and others. The level of evidence and methodological quality were assessed by two reviewers. Noninvasive brain stimulation and robotic rehabilitationwere frequently discussed in the top 50 articles. We found that therewas no difference in methodology quality between the top 50 articles in all years and the top ten articles in the past 5 yrs. Furthermore, the number of citations and citation density were not associated with the methodological quality. The findings suggest that the number of citations alone may not be a reliable indicator of research quality. [ABSTRACT FROM AUTHOR]

Objective: Pes anserine bursitis is the most common cause of periarticular knee pain. The aim of the study was to evaluate the efficacy of local injection-based therapies with different materials. Design: The enrolled patientswere randomly allocated to three groups to receive different interventions. Outcomemeasures included pain severity using the visual analog scale and the Western Ontario and McMaster Universities osteoarthritis index that was evaluated before the intervention, 1 and 8 wks after that. Results: This trial was performed on 72 participants, with male-tofemale ratio of 0.14 and with a mean age of 61.49 ± 9.35 yrs. Corticosteroids in the first group, oxygen-ozone in the second group, and dextrose 20% in the third group, were injected into the pes anserine bursa under ultrasound guidance. Interaction between time and group showed a statistically significant improvement in visual analog scale and Western Ontario andMcMaster Universities Arthritis Index (P = 0.05) in favor of corticosteroids and oxygen-ozone groups after 1 wk and in favor of oxygen-ozone and prolotherapy groups after 8 wks. Conclusions: All three treatment options are effective for patients with pes anserine bursitis. This study showed that the effects of oxygen-ozone injection and prolotherapy last longer than those of corticosteroid injection. [ABSTRACT FROM AUTHOR]

BACKGROUND: Noninvasive, precision monitoring of hepatocellular carcinoma (HCC) treatment efficacy would greatly facilitate personalized therapy and improve patient outcomes. We hypothesize that quantifying methylated circulating tumor DNA (ctDNA) can be used to effectively monitor HCC burden without the need for biopsy. STUDY DESIGN: Blood samples were collected from 25 patients, 21 with HCC and 4 with benign liver masses, at various timepoints throughout the course of treatment at a high-volume academic medical center. Quantification of methylated ctDNA molecules assessed CpG sites on more than 550 preselected cancer-specific amplicons. The tumor methylation score (TMS) was calculated by measuring the difference between the amount of methylation in the plasma and buffy coat with a normal cutoff value of 120 or less. RESULTS: Among 10 patients with surgical HCC (5 surgical resections and 5 liver transplants), TMS revealed a statistically significant, rapid postoperative decline in 9. One patient who had a persistently elevated TMS on postoperative day 1 was subsequently found to have had metastatic disease. Patients in the negative control cohort all had normal-range pre- and postoperative TMS. Preoperative TMS correlated moderately with tumor burden on pathology (Spearman r = 0.54) of surgical specimens. From 11 subjects undergoing systemic therapy or Y90 radioembolization, analysis of 16 time periods demonstrated that the change in TMS (ΔTMS) was better associated with tumor progression than the change in Δalpha-fetoprotein (area under the curve 0.800 and 0.783, respectively). A composite score combining ΔTMS and Δalpha-fetoprotein further improved performance for detecting tumor progression with an area under the curve of 0.892. CONCLUSIONS: These findings indicate that ctDNA methylation scores can effectively evaluate changes in tumor burden without the need for tumor biopsy. [ABSTRACT FROM AUTHOR]

BACKGROUND: Vertical sleeve gastrectomy is the most performed bariatric operation in the US; however, a significant number of patients suffer from persistent or new-onset reflux. No consensus for objective preoperative evaluation in these patients exists. We compared capsule-based pH testing vs GERD symptom scoring to determine extent of preoperative GERD to aid in procedure selection for bariatric surgery. STUDY DESIGN: An IRB-approved retrospective review of consecutive patients at a single institution was performed from April 2021 to December 2022. During initial consultation for bariatric surgery, a validated GERD symptom subjective survey was administered. All patients demonstrating interest in sleeve gastrectomy or had a history of reflux underwent upper endoscopy with capsule-based pH testing. RESULTS: Sixty-two patients underwent preoperative endoscopy with capsule-based pH testing and completed GERD symptom assessment survey(s). Median BMI was 43.4 kg/m² and 66.1% of patients were not taking a proton-pump inhibitor before performance of pH testing. There was negligible linear association between the objective DeMeester score obtained by capsule-based pH probe and GERD symptom survey scores. Median GERD symptom survey scores did not differ between patients with and without a diagnosis of GERD based on pH testing (all p values >0.11). CONCLUSIONS: An objective method for identifying severe GERD in the preoperative assessment may aid in the decision tree for procedure selection and informed consent process. Patients with significant preoperative GERD may be at higher risk for future GERD-related sleeve complications. Capsule-based pH testing may prove to be superior to subjective symptom scoring systems in this patient population. [ABSTRACT FROM AUTHOR]

BACKGROUND: The American Board of Surgery has endorsed competency-based education as vital to the assessment of surgical training. From 2018 to 2020, a national pilot study was conducted at 28 general surgery programs to evaluate feasibility of implementing entrustable professional activities (EPAs) for 5 common general surgical conditions. ACGME core competency Milestones were also rated for each resident by program clinical competency committees. This study aimed to evaluate the validity of general surgery EPAs compared with Milestones. STUDY DESIGN: Prospectively collected, de-identified EPA Pilot Study data were analyzed. EPAs studied were EPA-1 (gallbladder), EPA-2 (inguinal hernia), EPA-3 (right lower quadrant pain), EPA-4 (trauma), and EPA-5 (consult). Variables abstracted included levels of EPA entrustment (1 to 5) and corresponding ACGME Milestone subcompetency ratings (1 to 5) for the same study cycle. Spearman's correlations were used to evaluate the relationship between summative EPA scores and corresponding Milestone ratings. RESULTS: A total of 493 unique residents received a summative entrustment decision. EPA summative entrustment scores had moderate-to-strong positive correlation with mapped Milestone subcompetencies, with median rho value of 0.703. Among operation-focused EPAs, median rho values were similar between EPA-1 (0.688) and EPA-2 (0.661), but higher for EPA-3 (0.833). EPA-4 showed a strong positive correlation with diagnosis and communication competencies (0.724), whereas EPA-5, mapped to the most Milestone subcompetencies, had the lowest median rho value (0.455). CONCLUSIONS: Moderate-to-strong positive correlation was noted between EPAs and patient care, medical knowledge, and communication Milestones. These findings support the validity of EPAs in general surgery and suggest that EPA assessments can be used to inform Milestone ratings by clinical competency committees. [ABSTRACT FROM AUTHOR]

Objective: The aim of the study is to assess the relationship between walking exercise and medial joint space narrowing progression, symptoms, and knee extensor muscle strength in early knee osteoarthritis patients. Methods: This nested cohort study within the Osteoarthritis Initiative included participants aged 50 yrs and older with knee osteoarthritis (Kellgren-Lawrence grades 0–2). Walking exercisers were identified using a modified Historical Physical Activity Survey Instrument. Differences in medial joint space narrowing, Knee Injury and Osteoarthritis Outcome Score, and knee extensor muscle strength were evaluated through the three-way analysis of variance. Results: Among 896 participants, 83.4% reported walking exercise. Female walkers showed significant improvements in symptoms (Knee Injury and Osteoarthritis Outcome Score–pain: P < 0.001; Knee Injury and Osteoarthritis Outcome Score–symptom: P < 0.001; Knee Injury and Osteoarthritis Outcome Score–quality of life: P < 0.001; Knee Injury and Osteoarthritis Outcome Score–function, sports, and recreational activities: P = 0.007). Similar results were observed in male walkers (Knee Injury and Osteoarthritis Outcome Score–pain: P < 0.001; Knee Injury and Osteoarthritis Outcome Score–symptom: P < 0.001; Knee Injury and Osteoarthritis Outcome Score–quality of life: P = 0.001; Knee Injury and Osteoarthritis Outcome Score–function, sports, and recreational activities: P = 0.009). Walkers showed significantly increased knee extensor muscle strength at 24 mos (female: P < 0.001; male: P = 0.003). Female nonwalkers had significantly decreased knee extensor muscle strength at 24 mos (P < 0.001). Walkers showed significant improvement in medial joint space narrowing (odds ratio = 1.1, 95% confidence interval = 1.0–1.2) and Kellgren-Lawrence grade (OR = 1.0, 95% CI = 1.0–1.1) compared with nonwalkers. Conclusions: Walking exercise prevents structural progression and improves symptoms. Meanwhile, the increased knee extensor muscle strength in all walkers further supports the validity of recommending walking exercises for early-stage knee osteoarthritis patients.

Objective: The aim of the study is to evaluate the effect of minimally invasive ultrasound-guided fascial release and a foot orthoses with first metatarsal head cutout on the biomechanics of the medial longitudinal arch of the foot in cadaveric specimens. Design: A cross-sectional study was designed (20 body donors). Anthropometric measurements of the foot, foot posture index, and the windlass test and force were measured in different conditions: unloaded, loaded position, with foot orthoses, after a 25% plantar fascia release and after a 50% release. Results: For the anthropometric measurements of the foot, differences were found in foot length (P = 0.009), arch height (P < 0.001), and midfoot width (P = 0.019) when comparing the unloaded versus foot orthoses condition. When foot orthoses were compared with 25% plantar fascial release, differences were found in foot length (P = 0.014) and arch height (P < 0.001). In the comparison with 50% plantar fascial release, differences were found in the arch height (P < 0.001). A significant interaction between foot orthoses condition and grades was found in the arch height during the windlass test (P = 0.021). Conclusions: The results indicate that the presence of foot orthoses leads to a significant increase in arch height compared with other conditions. Furthermore, when plantar fascia release is performed, the arch does not exhibit any signs of collapse. [ABSTRACT FROM AUTHOR]

Objective: The aim of the study is to evaluate the safety of onabotulinumtoxinA treatment for spasticity across dose ranges in real-world practice. Design: Adult Spasticity International Registry was a multicenter, prospective, observational study (NCT01930786) of onabotulinumtoxinA treatment for adult spasticity over 2 yrs. Adverse events, serious adverse events, treatment-related adverse events, and serious treatment-related adverse events were sorted into five categories (≤200, 201–400, 401–600, 601–800, ≥801 U) based on cumulative dose per session. Results: In 3103 treatment sessions (T), 730 patients received ≥1 dose of onabotulinumtoxinA. Dose categories included the following: ≤200 U (n = 312, T = 811), 201–400 U (n = 446, T = 1366), 401–600 U (n = 244, T = 716), 601–800 U (n = 69, T = 149), and ≥801 U (n = 29, T = 61). Of these patients, 261 reported 827 adverse events, 94 reported 195 serious adverse events, 20 reported 23 treatment-related adverse events, and 2 patients treated with 201–400 U onabotulinumtoxinA reported 3 serious treatment-related adverse events. Treatment-related adverse events reported included ≤200 U (8/811, 0.9%), 201–400 U (7/1366, 0.5%), 401–600 U (6/716, 0.8%), 601–800 U (1/149, 0.7%), and ≥801 U (1/61, 1.6%). Conclusions: In this post hoc analysis, most treatment sessions were performed with 201–400 U onabotulinumtoxinA. Patients treated with 201–400 U onabotulinumtoxinA had an adverse event profile consistent with onabotulinumtoxinA package inserts globally (e.g., United States, European Union, United Kingdom, Canada). No new safety signals were identified. [ABSTRACT FROM AUTHOR]

Objective: To investigate the effect of sensorimotor training on gait, ankle joint proprioception, and quality of life in diabetic peripheral neuropathy patients. Design: A prospective, single-blind, randomized controlled experiment was performed. Forty patients with diabetic peripheral neuropathy aged 50–65 yrs were distributed randomly into two groups, the sensorimotor training group (n = 20), and the control group (n = 20). Both groups attended awareness sessions about diabetes and foot care for 30 mins, every 2 wks. Moreover, the sensorimotor training group received 6 wks (3 d/wk) of sensorimotor training. Spatiotemporal gait parameters, proprioception accuracy of the ankle joint, and quality of life were measured before and after 6 wks of intervention. Results: Regarding baseline data, no significant differences were identified among groups (P > 0.05). After 6-wk intervention, the sensorimotor training group exhibited significant improvements in all outcome variables (P < 0.001), while the control group showed significant changes in quality of life only (P = 0.03). Comparing groups after intervention reveals statistically significant differences in all measured variables in favor of the sensorimotor training group (P < 0.001). Conclusions: Sensorimotor training may improve spatiotemporal gait parameters, ankle joint proprioception, and quality of life of patients with diabetic peripheral neuropathy. [ABSTRACT FROM AUTHOR]

Background and Purpose: Pain assessment and management are an important issue to ensure the comfort of patients in the intensive care unit, and reducing pain is an important nursing intervention. Therefore, it is important to evaluate pain correctly. For correct pain management, it is necessary to correctly determine the presence and severity of pain. The studywas conducted to determine whether endotracheal suctioning was painless and whether the Behavioral Pain Scale (BPS) was an accurate assessment tool to assess pain during endotracheal suctioning. Methods: This study is a prospective clinical study. Thirty-two patients were endotracheal suctioned using the same technique by the same person, and their before-procedure BPS and visual analog scale (VAS) scores were recorded. The study was conducted in the anesthesia and reanimation intensive care unit of a university hospital between December 12, 2020, and April 14, 2021. Results: The before-procedure BPS and VAS scores indicated no pain. There was an increase in the procedure BPS score, whereas the VAS score did not change. Conclusions: Endotracheal suctioning did not cause pain in conscious patients when the procedure was performed with the correct catheter in accordancewith the guideline. In addition, it can be said that BPS is not sufficient to evaluate pain, but the reason for its high level is because endotracheal suctioning is an uncomfortable procedure. Of course, more studies and further studies are needed for a clear result. It is important for health care professionals to relieve or reduce the pain of patients during the endotracheal aspiration procedure. In addition, the presence and severity of pain associated with the endotracheal aspiration procedure should be accurately measured.. This study is registered in ClinicalTrials.gov with the IDNCT04634474. [ABSTRACT FROM AUTHOR]

Background: Although family caregivers experienced negative psychological symptoms associated with witnessing intensive care unit deliriumin their loved ones, there is a lack of clear understanding of how delirium is associated with family caregiver psychological distress. Uncertainty could be a factor contributed to this association. Objectives: The aim of this study was to examine the relationship between uncertainty and psychological distress among family caregivers of patients with delirium in intensive care units. Methods: A cross-sectional correlational design was used for this observational study of adult family caregivers of patients admitted to the intensive care unit and who reported witnessing delirium symptoms in their loved ones. Family caregivers completed an electronic survey in January 2022 that consisted of a family caregiver and patient demographic form, the Mishel Uncertainty in Illness Scale-Family Member, and the Kessler Psychological Distress Scale. Descriptive, correlational, and regression statistical analyses were applied. Results: One hundred twenty-one adult family caregivers were enrolled. Family caregivers reported substantial uncertainty (mean, 106.15, on a scale of 31-155) and moderate to severe psychological distress (mean, 31.37, on a scale of 10-50) regarding their witnessing of delirium episodes in their loved ones. Uncertainty was significantly correlated with psychological distress among family caregivers (rs = 0.52, P < .001). Uncertainty significantly predicted psychological distress among family caregivers (regression coefficient, 0.27; P < .001). Discussion: Family caregiver uncertainty was positively associated with psychological distress. This distress can interfere with family caregiver involvement in patient delirium care. These findings are essential to increase critical care nurse awareness and inform the development of nursing interventions to alleviate possible uncertainty and distress. [ABSTRACT FROM AUTHOR]

Background: It is important to detect oral health problems early among patients admitted to pediatric intensive care units to establish the diagnosis and consequently allow nurses to plan appropriate oral care practices. Objectives: The study aimed to assess the oral health status of patients admitted to pediatric intensive care units. Methods: This descriptive cross-sectional study was conducted from June to September 2021 in the pediatric intensive care units of 3 hospitals. A total of 88 children were included in the study. An intraoral assessment was performed using a tongue depressor and a flashlight, and data were collected using a patient information form and the Oral Assessment Guide (OAG). Results: The mean OAG score was 8.45 ± 2.876 points. A significant difference was found in the OAG score between the patients 60months or younger and those 61months or older (P < .05). The OAG score was significantly associated with the use of diuretics (P < .05) and the frequency of oral care (P < .05). A negative relationship was found between the OAG score and the Glasgow Coma Scale score (P < .05). Conclusions: The oral health status of the patients worsened as their age increased, and their state of consciousness decreased. Oral care was more frequently applied to the patientswho received artificial respiration. The study provides evidence-based data regarding the early detection of the factors threatening oral health and the necessary precautions. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to investigate the effect of an isometric (ISO) or Nordic hamstring exercise (NHE) intervention, alongside a sprint training program on hamstring strength, architecture, and sprinting performance in Australian footballers. Methods: Twenty-five male athletes undertook NHE (n = 13) or ISO (n = 12) training across a 38-wk period (including preseason and in season). Biceps femoris long head (BFlh) architecture, ISO, and eccentric knee flexor strength were assessed at baseline, at the end of preseason (14 wk), and at the conclusion of the intervention. Sprint times and force–velocity profiles were determined at baseline and at the end of preseason. Results: After the intervention, both groups had significant improvements in BFlh fascicle length (NHE: 1.16 cm, 95% CI = 0.68 to 1.63 cm, d = 1.88, P < 0.001; ISO: 0.82 cm, 95% CI = 0.57 to 1.06 cm, d = 1.70, P < 0.001), muscle thickness (NHE: 0.11 cm, 95% CI = 0.01 to 0.21 cm, d = 0.51, P = 0.032; ISO: 0.21 cm, 95% CI = 0.10 to 0.32 cm, d = 0.86, P = 0.002), and eccentric strength (NHE: 83 N, 95% CI = 53 to 114 N, d = 1.79, P < 0.001; ISO: 83 N, 95% CI = 17 to 151 N, d = 1.17, P = 0.018). Both groups also finished the intervention weaker isometrically than they started (NHE: −45 N, 95% CI = −81 to −8 N, d = −1.03, P = 0.022; ISO: −80 N, 95% CI = −104 to −56 N, d = −3.35, P < 0.001). At the end of preseason, the NHE group had improved their 5-m sprint time by 3.3% ± 2.0%), and their maximum horizontal velocity was 3% ± 2.1% greater than the ISO group who saw no changes. Conclusions: Both ISO and NHE training with a periodized sprinting program can increase BFlh fascicle length, thickness, and eccentric strength in Australian footballers. NHE training also improves 5-m sprint time and maximum velocity. However, both interventions reduced ISO strength. These findings provide unique, contextually relevant insights into the adaptations possible in semiprofessional athletes. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to evaluate whether motor–respiratory coupling exists in rhythmic isometric handgrip exercises and its effect on endurance performance. In addition, the mechanism underlying observed effects was to be investigated if higher motor–respiratory coupling rate could enhance endurance performance. Methods: Eleven subjects completed three rhythmic isometric handgrip trials to task failure in a randomized manner. After one pretraining session to determine personal grip frequency, one trial was performed without respiration requirement (CON), and two trials were performed with inspiration–motor coupling (IMC) or expiration–motor coupling. Changes in maximal voluntary contraction (MVC) and EMG were used to measure neuromuscular fatigue. Force data during test were used to assess exercise intensity. Another 10 subjects completed electrical stimulation-induced finger flexion and extension during normal inspiration, normal expiration, fast inspiration, fast expiration, and breath holding. Force changes of different breathing conditions were compared. Results: Normalized exercise time to exhaustion was significantly longer in IMC (1.27 ± 0.23) compared with expiration–motor coupling (0.82 ± 0.18) and CON (0.91 ± 0.18, P < 0.001). ΔMVC, grip frequency, force, and EMG indices were not different among conditions (all P > 0.05). Electrical stimulation-induced finger extensor force was significant higher during fast inspiration (1.11 ± 0.09) than normal respiration (1.00 ± 0.05) and fast expiration (0.94 ± 0.08, P < 0.05). Conclusions: IMC is an effective way to improve endurance performance of rhythmic handgrip exercise. This is likely due to a reduction in the energy consumption of motion control, as evidenced by similar peripheral fatigue in different conditions and modulation of corticospinal excitability by respiration.

Purpose: Long-chain omega-3 polyunsaturated fatty acids, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) may enhance recovery from exercise-induced muscle damage (EIMD). However, it is unclear if the effects are due to EPA, DHA, or both. The purpose of this investigation was to examine the effect of EPA + DHA, EPA, and DHA compared with placebo (PL) on muscular recovery. Methods: Thirty males were randomized to 4 g·d−1 EPA + DHA (n = 8), EPA (n = 8), DHA (n = 7), or PL (n = 7). After 7-wk supplementation, a downhill running (20 min, 70% V̇O2max, −16% gradient) plus jumping lunges (5 × 20 reps, 2-min rest intervals) muscle damage protocol was performed. Indices of muscle damage, soreness, muscle function, and inflammation were measured at baseline and throughout recovery. The omega-3 index (O3i; %EPA + %DHA in erythrocytes) was used to track tissue EPA and DHA status. Results: After supplementation, the O3i was significantly higher than PL in all experimental groups (P < 0.001). Leg press performance was lower in the PL group at 24 h compared with EPA (P = 0.019) and at 72 h for EPA (P = 0.004) and DHA (P = 0.046). Compared with PL, muscle soreness was lower in the DHA (P = 0.015) and EPA (P = 0.027) groups at 48 h. Albeit nonsignificant, EPA + DHA tended to attenuate muscle soreness (d = 1.37) and leg strength decrements (d = 0.75) compared with PL. Jump performance and power metrics improved more rapidly in the EPA and DHA groups (time effects: P < 0.001). Measures of inflammation, range of motion, and muscle swelling were similar between groups (P > 0.05). Conclusions: Compared with PL, 4 g·d−1 of EPA or DHA for 52 d improves certain aspects of recovery from EIMD. EPA + DHA did not clearly enhance recovery. Equivalent dosing of EPA + DHA may blunt the performance effects observed in EPA or DHA alone. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to determine how the intersection of coactivator-associated arginine methyltransferase 1 (CARM1) and biological sex affects skeletal muscle adaptations to chronic physical activity. Methods: Twelve-week-old female (F) and male (M) wild-type (WT) and CARM1 skeletal muscle-specific knockout (mKO) mice were randomly assigned to sedentary (SED) or voluntary wheel running (VWR) experimental groups. For 8 wk, the animals in the VWR cohort had volitional access to running wheels. Subsequently, we performed whole-body functional tests, and 48 h later muscles were harvested for molecular analysis. Western blotting, enzyme activity assays, as well as confocal and transmission electron microscopy were used to examine skeletal muscle biology. Results: Our data reveal a sex-dependent reduction in VWR volume caused by muscle-specific ablation of CARM1, as F CARM1 mKO mice performed less chronic, volitional exercise than their WT counterparts. Regardless of VWR output, exercise-induced adaptations in physiological function were similar between experimental groups. A broad panel of protein arginine methyltransferase (PRMT) biology measurements, including markers of arginine methyltransferase expression and activity, were unaffected by VWR, except for CARM1 and PRMT7 protein levels, which decreased and increased with VWR, respectively. Changes in myofiber morphology and mitochondrial protein content showed similar trends among animals. However, a closer examination of transmission electron microscopy images revealed contrasting responses to VWR in CARM1 mKO mice compared with WT littermates, particularly in mitochondrial size and fractional area. Conclusions: The present findings demonstrate that CARM1 mKO reduces daily running volume in F mice, as well as exercise-evoked skeletal muscle mitochondrial plasticity, which indicates that this enzyme plays an essential role in sex-dependent differences in exercise performance and mitochondrial health.

Objective: In middle-aged individuals with early-stage knee osteoarthritis, follow-up with remote rehabilitation methods may provide effective clinical outcomes. The present study aimed to investigate the effect of telerehabilitation on pain, function, performance, strength, proprioception, and psychosocial parameters in patients with knee osteoarthritis. Design: A randomized controlled study was conducted with 54 participants with knee osteoarthritis. All patients were randomized into two groups: the home-based telerehabilitation group (n = 29) and the home-based paper group (n = 28). The home exercise program and training were provided with an instruction manual to paper group. The same home exercise and education prescriptions were given to individuals in telerehabilitation group via an online platform. Pain, function, quality of life, physical performance, muscle strength, and proprioception were evaluated at baseline and after 8 wks of intervention. In addition, satisfaction and usability were evaluated at week 8. Results: Telerehabilitation group demonstrated better improvement in terms of pain, function, quality of life index score, and left extremity proprioception (P < 0.05). Telerehabilitation group was not superior to paper group in terms of muscle strength and performance tests (except the Five Times Sit to Stand Test) (P > 0.05). Conclusions: The home-based telerehabilitation program was superior to the home-based paper group program for pain, function, quality of life, and proprioception in patients with knee osteoarthritis.

Background: Adhesive capsulitis affects the shoulder joint, causing pain and limiting motion. In clinical practice, the effectiveness of injections varies, and the factors influencing their success remain unclear. This study investigates the predictors of effective corticosteroid injections in patients with primary adhesive capsulitis. Design: This retrospective study enrolled adhesive capsulitis patients older than 35 yrs who received intra-articular corticosteroid injections. The response was determined based on patients' pain and range of motion 3 mos after the injection. Demographic data, medical comorbidities, and radiographic parameters (critical shoulder angle and acromial index) were compared between the effective and noneffective groups. Receiver operating characteristic curves and logistic regression were used to identify the predictors of injection effectiveness. Results: This study included 325 patients with primary adhesive capsulitis, who were divided into responder (189 patients, 58.2%) and nonresponder (136 patients, 41.8%) groups. The receiver operating characteristic curve revealed that the acromial index score indicated favorable discrimination for predicting a poor response to injections, whereas the critical shoulder angle score did not. Logistic regression revealed that the pain period, diabetes mellitus, and acromial index are predictors of nonresponders to injections. Conclusions: Long pain duration, the presence of diabetes mellitus, and an acromial index score greater than 0.711 were predictors of nonresponse to corticosteroid injections for primary adhesive capsulitis patients.

Objective: The aims of the study are to assess the quality of sleep in recently recovered COVID-19 and long-COVID cases and to determine its associations with fatigue and pain. Methods: Post–COVID-19 cases (n = 201) and controls (n = 206) were assessed using the Pittsburgh Sleep Quality Index questionnaire for sleep quality, Fatigue Severity Scale for fatigue, and Numeric Pain Rating Scale for pain in this observational study. Results: Global Pittsburgh Sleep Quality Index score was higher (P ≤ 0.001) among cases (5.7 ± 5.1; 95% confidence interval, 5.0–6.4) than controls (2.1 ± 2.0; 95% confidence interval, 1.8–2.4). Normal sleep latency was observed in 56 (27.9%) patients and 164 (79.6%) controls (P < 0.001). Fatigue Severity Scale score was higher (P ≤ 0.001) among cases (16.8 ± 10.2; 95% confidence interval, 15.4, 18.2) against controls (10.9 ± 4.1; 95% confidence interval, 10.3–11.4). The Fatigue Severity Scale scores in mild, moderate, and severe COVID-19 were 14.3 ± 8.1, 22.1 ± 10.8, and 22.8 ± 13, respectively (P < 0.001) and higher in the older (20.7 ± 12.1) and middle-aged (19.6 ± 10.3) than in younger (13.9 ± 8.3) (P ≤ 0.001) cases. The global Pittsburgh Sleep Quality Index score was positively correlated with the Fatigue Severity Scale (r = 0.755, P < 0.001) and Numeric Pain Rating Scale scores (r = 0.657, P < 0.001). Numeric Pain Rating Scale score correlated with Fatigue Severity Scale score (r = 0.710, P < 0.001). Fatigue Severity Scale and global Pittsburgh Sleep Quality Index scores were higher in the long-COVID group (P < 0.001). Conclusions: Significantly poor sleep quality was observed in post–COVID-19 individuals including long COVID being positively associated with fatigue and pain. [ABSTRACT FROM AUTHOR]

OBJECTIVE: The aim of this study was to determine relationships between moral injury (MI) and self-reported nurse work performance (NWP) among hospital nurses after the COVID-19 pandemic surges. BACKGROUND: Previously studied in the military, nurse MI became evident due to the pandemic. No previous studies have examined the impact of MI on NWP. Few studies have attended to how MI in nurses can be addressed by nursing leadership. METHODS: A convenience sample of 191 nurses from 7 hospitals in Southern California participated in a multisite correlational survey-design study. RESULTS: Significant levels of MI occurred in 57% (n = 114) of participants. Increased levels of MI were a significant predictor of decreased levels of self-reported NWP. Younger and less experienced nurses reported greater levels of MI. CONCLUSIONS: This study relates MI in nurses to NWP. There is a need for further research to assist nursing administrators in ameliorating MI in nurses and in preparing for the impact of MI on the nursing workforce in future emergent situations.

Background: It is not known whether behavioral weight loss can attenuate blood oxygen level-dependent responses to food stimuli. Objectives: This randomized controlled trial assessed the effects of a commercially available behavioral weight loss program (WW, WeightWatchers) compared to a wait-list control on blood oxygen level-dependent response to food cues. Methods: Females with obesity (N = 61) were randomized to behavioral weight loss or wait-list control. At baseline and follow-up, participants completed assessments that included functional magnetic resonance imaging scans to assess response to images of high-calorie foods (HCF) or low-calorie foods (LCF), and neutral objects. Results: There were no significant between-group differences in change from baseline to follow-up in any regions of the brain in response to viewing HCF or LCF. From baseline to follow-up, participants in behavioral weight loss, compared with wait-list control, reported significantly greater increases in desire for LCF. Changes in liking and palatability of LCF and liking, palatability, and desire for HCF did not differ between groups. Discussion: Behavioral weight loss was associated with increased desire for LCF without changes in neural reactivity to food cues. These results suggest that alteration of neurological processes underlying responsiveness to food is difficult to achieve through behavioral weight management alone. [ABSTRACT FROM AUTHOR]

BACKGROUND: Trauma center benchmarking has become standard practice for assessing quality. The American College of Surgeons adult trauma center verification standards do not specifically require participation in a pediatric-specific benchmarking program. Centers that treat adults and children may therefore rely solely on adult benchmarking metrics as a surrogate for pediatric quality. This study assessed discordance between adult and pediatric mortality within mixed trauma centers to determine the need to independently report pediatric-specific quality metrics. STUDY DESIGN: A cohort of trauma centers (n = 493, including 347 adult-only, 44 pediatric-only, and 102 mixed) that participated in the American College of Surgeons TQIP in 2017 to 2018 was analyzed. Center-specific observed-to-expected mortality estimates were calculated using TQIP adult inclusion criteria for 449 centers treating adults (16 to 65 years) and using TQIP pediatric inclusion criteria for 146 centers treating children (0 to 15 years). We then correlated risk-adjusted mortality estimates for pediatric and adult patients within mixed centers and evaluated concordance of their outlier status between adults and children. RESULTS: The cohort included 394,075 adults and 97,698 children. Unadjusted mortality was 6.1% in adults and 1.2% in children. Mortality estimates had only moderate correlation (r = 0.41) between adult and pediatric cohorts within individual mixed centers. Mortality outlier status for adult and pediatric cohorts was discordant in 31% (32 of 102) of mixed centers (weighted Kappa statistic 0.06 [-0.11 to 0.22]), with 78% (23 of 32) of discordant centers having higher odds of mortality for children than for adults (6 centers with average adult mortality and high pediatric mortality and 17 centers with low adult mortality and average pediatric mortality, p < 0.01). CONCLUSIONS: Adult mortality is not a reliable surrogate for pediatric mortality in mixed trauma centers. Incorporation of pediatric-specific benchmarks should be required for centers that admit children. [ABSTRACT FROM AUTHOR]

Objective: The aim of this cross-sectional study was to examine the recovery from work in Finnish home care nurses with objective and subjective recovery measures. Methods: Heart rate and heart rate variability recordings were performed in home care nurses over a period of one work shift and the following night. Following the measurements, the participants (N = 91) answered a questionnaire including questions about their self-rated recovery from work and sleep disturbances. Results: The objectively measured recovery was within the recommended heart rate variability range, yet the self-rated recovery from work was only mediocre. Subjective recovery was not associated with objectively measured recovery. Conclusions: There is a discrepancy between objectively and subjectively measured recovery from work. Therefore, an additional objective method in occupational field studies, along with questionnaires, is recommended to measure physiological recovery. [ABSTRACT FROM AUTHOR]

Background: The purpose of this study was to assess the prevalence and sequelae of insomnia, obstructive sleep apnea (OSA), and comorbid OSA and insomnia (COMISA). Method: In the morning, after a shift end, Midwest career firefighters (N= 89) in a midsized city completed an electronic battery of ques-tionnaire to screen for OSA, daytime sleepiness, insomnia, presleep arousal, nightmares, mental and physical health symptoms, and a one-night sleep diary. Results: Prevalence of firefighters exceeding screening thresholds: OSA: 54%; insomnia: 30%; COMISA: 17%; four or more nightmares per month: 15%. Firefighters who met criteria for COMISA had shortertotal sleep time, less restful and worse sleep quality, higher depression and anxiety symptoms, and presleep arousal symptoms than firefighters without self-reported sleep problems. Conclusions: Many firefighters are at elevated risk of individual behavioral sleep disorders, COMISA, and daytime dysfunction. [ABSTRACT FROM AUTHOR]

Background: During a program review, faculty identified that nurse practitioner (NP) students who received a C grade in Advanced Pathophysiology (Patho) and Advanced Pharmacology (Pharm) appeared to perform poorly in the later NP management courses and on other program outcomes. Purpose: The research aimed to determine whether grades in graduate Patho and Pharm courses could predict performance in NP management courses, program progression and completion, and certification pass rates. Methodology: This research included deidentified student data from 2016 to 2018 across seven NP specialty tracks (n = 4,575). Nonparametric and parametric tests were used in the analysis. Results: A significant correlation (p < .001) existed between Patho and Pharm grades. Lower grades in these two courses were significantly related to each other and to lower management course grades. Logistic regression showed that graduate pathophysiology grades significantly predicted certification examination performance, with lower grades associated with lower certification examination performance. Graduate pharmacology grades, pathophysiology grades, composite management course grades, and admission grade point average (GPA) significantly predicted final cumulative GPA, with lower grades associated with lower performance for all variables. Conclusions: Results of this research support the hypothesis that grades of C in Patho or Pharm courses significantly predict C performance in the management NP courses and lower certification success rates. Implications: The project model can be used in future research. Study findings can be helpful to NP faculty when considering curriculum decisions. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Orthosis and physical therapy are two conservativemanagements for knee osteoarthritis (OA), but the question is which is better for alleviating pain and improving function? The aim of this study was to compare two interventions of orthosis and physical therapy on pain and function in patients with knee OA. Methods: In this quasi-experimental study, 31 individuals with medial knee OA were recruited into two groups including orthosis group (combination of insole and brace [n = 14]) and physical therapy group (n = 17). Pain severity was measured by visual analog scale (VAS) andWestern Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire. Also, daily activity was measured by the WOMAC questionnaire at baseline and after 6-week follow-up. Wilcoxon signed rank and Mann-Whitney U tests were used to determine significant difference for intragroup and intergroup comparisons, respectively. Results: The orthosis group (using both knee brace and LWLs) had a better result for pain score related to VAS than the physical therapy group immediately after and 6 weeks of using the intervention, with a significant difference between the two groups (P = 0.006). Regarding the WOMAC items including pain and daily activity, both groups had significant differences after the 6-week period of using the intervention, with no significant difference between the groups. Conclusions: Based on the findings, pain and daily activity related to the WOMAC questionnaire were improved in both orthosis and physical therapy groups, with no differences between the two interventions. The orthosis group had better results in pain related to VAS. Clinical Relevance: The aim of this study was to find whether physical therapy or orthosis best improves pain and function of knee OA patients. [ABSTRACT FROM AUTHOR]

Introduction: Effective communication is key to the development of a successful interdisciplinary team, and effective communication cannot be achieved without an accurate understanding of role awareness. Communication within interdisciplinary teams may be particularly important for orthotists given their highly specialized scope of practice, the limited public awareness of the profession, and relatively recent increases to minimum education requirements. Because physical therapists (PTs) and orthotists commonly work together to restoremobility, the purpose of this study was to determine if there are factors associated with the perceived value of orthotists as members of the health care team among PTs. Materials and Methods: This study consisted of a cross-sectional survey assessing demographic characteristics and four value variables. The survey was distributed via email using snowball sampling to health care teammembers. Responses fromPTs were analyzed through a series of statistical testing for significant correlations of the demographic characteristics and value variables. Results: A total of 68 responses from PTs were included in the final analysis. Mutual patient goal setting contact showed a statistically significant relationship with frequency of contact and the perceived skill level of orthotists. The mean orthotist skill level was 86.57 (±10.24, min = 59, max = 100). The frequency of mutual patient goal setting contact was higher for PTs who were younger, had a higher level of education, and fewer years of experience. Conclusions: Despite its rich history, orthotics may be considered relatively new as a profession, and orthotists are often still establishing their role within a teamsetting. Mutual patient goal settingmay provide a key opportunity for orthotists to increase awareness of their skill set and demonstrate their value as professional members of the health care team. Interprofessional education is another opportunity to increase role awareness and may explain why younger PTs with higher levels of education and fewer years of experience were more likely to set mutual patient goals with orthotists. Clinical Relevance: The results of this study show that engaging in mutual patient goal setting with PTs may be an avenue for orthotists to demonstrate their skills, knowledge, and, ultimately, their value.

Introduction: Traditionally, lower-limb prostheses are composed of passive components, which provide a fraction of the push-off power of the natural ankle-foot complex. In individuals with transtibial amputation (TTA), this leads to deviations and compensatory mechanisms. Studies have reported significant unloading of the sound limb and knee joint with a powered prosthetic ankle-foot. However, despite the promising biomechanical evidence on unloading, no study has yet investigated the impact of powered prosthetic ankle-foot on musculoskeletal pain. Methods: A total of 250 individuals fit with a powered prosthetic ankle-foot component were invited to participate in an institutional review board-approved cross-sectional study. Participants completed a survey, which collected typical prosthetic history information as well as Numerical Pain Rating Scales across different body regions, the Socket Comfort Score (SCS), the Activity of Daily Living domain of the Knee Injury and Osteoarthritis Outcome Score (KOOS-ADL), and the Oswestry Disability Index (ODI) for both their current and past prosthetic ankle-foot. The differences between results across the two ankle-feet were evaluated in subgroups dependent on the user's current foot. Results: A total of 57 individuals met the inclusion criteria after completion of the online survey. Forty-one subjects (71.9%) identified as current powered ankle-foot users. Sixteen subjects (28.1%) reported to have used a powered ankle-foot in the past but have since abandoned it. The current powered ankle-foot users' group saw no significant difference in SCSs. The current passive foot users reported significantly (P = 0.002) better socket comfort for the prosthesis with the passive foot. The original and recall-adjusted median ratings of pain in the group of 41 current powered ankle-foot users showed significantly less pain in all three body segments. In the group of 41 current powered ankle-foot users, both the original and recall-adjusted KOOS-ADL and ODI scores were significantly better for the powered ankle-foot. Conclusions: Individuals in active daily life with TTA may experience relief of sound knee, amputated side knee, and low-back pain, as well as pain-related restrictions in activities of daily living function with use of a powered ankle-foot mechanism. Clinical Relevance: Providing the right patient with a powered ankle-foot has the potential to decrease the individual's pain. The individual may also have fewer pain-related functional restrictions when attempting to achieve activities of daily living. [ABSTRACT FROM AUTHOR]

Background: In the last decades, the use of the helmet interface to deliver noninvasive respiratory support has steadily increased. When delivering oxygen therapy, conditioning of inspired gas is mandatory, as the water content of medical gas is neglectable. To minimize the risk of airway damage, it is recommended to achieve an absolute humidity greater than 10 mg H2O/L. The primary aim of the study was to assess the performance of 3 different heated humidifiers to condition gas during helmet continuous positive airway pressure and to compare them with a setting without active humidification. Methods: We performed a crossover randomized physiological study in healthy volunteers. Absolute humidity, relative humidity, and temperature were measured during 4 steps (no humidification and the 3 heated humidifiers, performed in a randomized order) and at 3 time points (after 1, 5, and 10 minutes). Results: Eight subjects participated to the study. Without active humidification, absolute humidity was constantly below the recommended level. All humidifiers conditioned the inspired gases to an average absolute humidity greater than 10 mg H2O/L. Overall, the best performance, in terms of absolute humidity, was obtained with H900 (19.74 ± 0.50 mg H2O/L), followed by TurbH2O (−6.82 mg H2O/L vs H900; 95% confidence interval, −8.49 to −5.14; P <.05) and F&P 810 (−9.03 mg H2O/L vs H900; 95% confidence interval, −10.70 to −7.35; P <.05). Conclusions: Active humidification is required to achieve adequate conditioning of inspired gas during helmet continuous positive airway pressure. The choice between different humidifiers available on the market should be made according to the local needs and expertise. [ABSTRACT FROM AUTHOR]

Supplemental Digital Content is Available in the Text. Introduction: Comprehending scientific information have been reported as a barrier in evidence-based practice (EBP) adoption. This survey research aimed to verify the preferred sources of information for acquiring knowledge about physiotherapy and the association between types of information source and barriers in EBP implementation. Methods: A total of 610 physiotherapists were included and answered an online questionnaire about the preferred sources for searching physiotherapy-related information and possible barriers in EBP implementation. Results: Physiotherapists reported scientific resources as the preferred source of information, scientific databases (31%), followed by scientific articles (25%). The main barrier cited in EBP implementation was the difficulty in obtaining full-text articles (34%), followed by lack of statistical knowledge (30%). The use of peer-reviewed resources as the most preferred source of information is associated with the presence of issues in comprehending scientific information. Discussion: Although the positive attitude toward the use of scientific information, the findings raised question regarding the proper translation of scientific information to clinical practice. The importance of scientific information seems to be a well-established attitude among physiotherapists. However, there is a clear need for strategies aiming to improve the understanding of scientific information and consequently facilitate EBP implementation. [ABSTRACT FROM AUTHOR]

Introduction: There is limited knowledge on pediatric chest radiograph (pCXR) interpretation skill among practicing physicians. We systematically determined baseline interpretation skill, the number of pCXR cases physicians required complete to achieve a performance benchmark, and which diagnoses posed the greatest diagnostic challenge. Methods: Physicians interpreted 434 pCXR cases via a web-based platform until they achieved a performance benchmark of 85% accuracy, sensitivity, and specificity. Interpretation difficulty scores for each case were derived by applying one-parameter item response theory to participant data. We compared interpretation difficulty scores across diagnostic categories and described the diagnoses of the 30% most difficult-to-interpret cases. Results: 240 physicians who practice in one of three geographic areas interpreted cases, yielding 56,833 pCXR case interpretations. The initial diagnostic performance (first 50 cases) of our participants demonstrated an accuracy of 68.9%, sensitivity of 69.4%, and a specificity of 68.4%. The median number of cases completed to achieve the performance benchmark was 102 (interquartile range 69, 176; min, max, 54, 431). Among the 30% most difficult-to-interpret cases, 39.2% were normal pCXR and 32.3% were cases of lobar pneumonia. Cases with a single trauma-related imaging finding, cardiac, hilar, and diaphragmatic pathologies were also among the most challenging. Discussion: At baseline, practicing physicians misdiagnosed about one-third of pCXR and there was up to an eight-fold difference between participants in number of cases completed to achieve the standardized performance benchmark. We also identified the diagnoses with the greatest potential for educational intervention. [ABSTRACT FROM AUTHOR]
