Background: Older adults with cognitive impairment (CI) have higher multimorbidity and frailty prevalence, lower functional status and an increased likelihood to develop dementia, non-cognitive deficits, and adverse health-related events. +AGIL, a real-world program for frail older adults in a primary care area of Barcelona, is a pragmatic, multi-component and integrated intervention implemented since 2016. It includes physical activity, nutrition, sleep hygiene, revision and adequacy of pharmacological treatment, detection of undesired loneliness and screening for CI; to improve physical function in community-dwelling older adults. We aimed to assess the + AGIL longitudinal impact on physical function among community-dwelling frail older persons with CI. Methods: An interventional cohort study included data from all the + AGIL consecutive participants from July 2016 until March 2020. Based on the comprehensive geriatric assessment, participants were offered a tailored multi-component community intervention, including a 10-week physical activity program led by an expert physical therapist. Physical performance was measured at baseline, three and six months follow-up. The pre-post impact on physical function was assessed by paired sample t-test for repeated samples. Linear mixed models were applied to analyze the + AGIL longitudinal impact. P-values < 0.05 were considered statistically significant. Results: 194 participants were included (82 with CI, based on previous diagnosis or the Mini-COG screening tool), 68% women, mean age 81.6 (SD = 5.8) yo. Participants were mostly independent in Activities of Daily Living (mean Barthel = 92.4, SD = 11.1). The physical activity program showed high adherence (87.6% attended ≥ 75% sessions). At three months, there was a clinically and statistically significant improvement in the Short Physical Performance Battery (SPPB) and its subcomponents in the whole sample and after stratification for CI [CI group improvements: SPPB = 1.1 (SD = 1.8) points, gait speed (GS) = 0.05 (SD = 0.13) m/s, Chair stand test (CST)=-2.6 (SD = 11.4) s. Non-CI group improvements: SPPB = 1.6 (SD = 1.8) points, GS = 0.08 (SD = 0.13) m/s, CST=-6.4 (SD = 12.1) seg]. SPPB and gait speed remained stable at six months in the study sample and subgroups. CI had no significant impact on SPPB or GS improvements. Conclusion: Our results suggest that older adults with CI can benefit from a multidisciplinary integrated and comprehensive geriatric intervention to improve physical function, a component of frailty.

Background: Physical tests are commonly used in patellar tendinopathy to aid the clinical diagnosis, assess the prognosis, and monitor treatment. However, it is still unknown whether these physical measures are associated with patient-reported outcomes after exercise therapy. Purpose: To identify the prognostic value of baseline physical test results and to determine the association between physical response after exercise therapy and clinical improvement over 24 weeks. Study Design: Case-control study; Level of evidence, 3. Methods: This study recruited 76 consecutive athletes with patellar tendinopathy who were randomized to 2 different programs of exercise therapy for 24 weeks. Athletes underwent a range of physical tests before and during exercise therapy (12 and 24 weeks), including isometric muscle strength (quadriceps and hip abductors), muscle flexibility (quadriceps, hamstrings, soleus, and gastrocnemius), vertical jump height, and visual analog scale (VAS) scores by palpation, after 3 jump trials, and after single-leg squat (VAS-SLS). The Victorian Institute of Sports Assessment–Patella (VISA-P) questionnaire was used as the primary patient-reported outcome. Linear mixed-effect models were used to assess the prognostic value of baseline physical tests. The change in VISA-P score was further dichotomized into clinical responsiveness (≥14 points) and nonresponsiveness (<14 points). Multiple linear and logistic regression models were performed to evaluate associations between physical response and clinical improvement. Results: Of the 76 included patients, 67 (88%) had complete follow-ups. The estimated mean VISA-P score increased by 23 points (95% CI, 19-28 points) after 24 weeks. No association was found between any baseline physical test results and a 24-week change in VISA-P score (all P interaction >.2, using the likelihood ratio test). Improvement in VAS-SLS after exercise therapy was not associated with VISA-P improvement after adjustment (β = −1.76; P =.01; Bonferroni-corrected P =.10; R 2 = 36.3%). No associations were found between changes in other physical test results and clinical improvement (all P >.05). Conclusion: In patients with patellar tendinopathy, physical test results including strength and flexibility in the lower limb, jump performance, and pain levels during pain-provoking tests were not identified as prognostic factors for patient-reported outcomes after exercise therapy. Similarly, changes in physical test results were not associated with changes in patient-reported outcomes after adjustments. These results do not support using physical test results to estimate prognosis or monitor treatment response. Registration: NCT02938143 (ClinicalTrials.gov identifier). [ABSTRACT FROM AUTHOR]

Background: Recently developed absolute and body size normalized handgrip strength (HGS) cut-points could be used individually and collectively to predict mobility problems and falls. Aims: We examined the associations of (1) each absolute and normalized weakness cut-point, (2) collective weakness categories, and (3) changes in weakness status on future falls in older Americans. Methods: The analytic sample included 11,675 participants from the 2006–2018 waves of the Health and Retirement Study. Falls were self-reported. Men were classified as weak if their HGS was < 35.5-kg (absolute), < 0.45 kg/kg (body mass normalized), or < 1.05 kg/kg/m2 (body mass index normalized). While, women were considered weak if their HGS was < 20.0-kg, < 0.337 kg/kg, or < 0.79 kg/kg/m2. Collective weakness categorized those below 1, 2, or all 3 cut-points. The collective weakness categories were also used to observe changes in weakness status over time. Results: Older Americans below each absolute and normalized cut-point had greater odds for future falls: 1.23 (95% confidence interval (CI): 1.15–1.32) for absolute weakness, 1.20 (CI 1.11–1.29) for body mass index normalized weakness, and 1.26 (CI 1.17–1.34) for body mass normalized weakness. Persons below 1, 2, or all 3 weakness cut-points had 1.17 (CI 1.07–1.27), 1.29 (CI 1.18–1.40), and 1.36 (CI 1.24–1.48) greater odds for future falls, respectively. Those in some changing weakness categories had greater odds for future falls: 1.26 (CI 1.08–1.48) for persistent and 1.31 (CI 1.11–1.55) for progressive. Discussion: Collectively using these weakness cut-points may improve their predictive value. Conclusion: We recommend HGS be evaluated in mobility and fall risk assessments. [ABSTRACT FROM AUTHOR]

• Muscle strength and mobility are similar in ICU and hospital discharge in patients admitted due to COVID-19 or other critical illnesses. • In ICU patients admitted due to COVID-19, better muscle strength and mobility at ICU discharge are associated with reduced hospital length of stay. • The cut-off <18 on the PICUMS at ICU discharge may indicate impaired physical functioning due to ICUAW. Critical illness may affect muscle strength and mobility. To compare muscle strength, mobility, and in intensive care unit (ICU)-acquired weakness (ICUAW) prevalence among individuals with COVID-19 and other critical illnesses; to identify factors associated with muscle strength, mobility, and length of stay in COVID-19; and to determine the Perme Intensive Care Unit Mobility Score (PICUMS) cut-off point for ICUAW. We included individuals aged ≥18 in ICU who require mechanical ventilation. We excluded those diagnosed with neuromusculoskeletal diseases or who did not understand the study procedures. The Medical Research Council - sum score (MRC-SS) and the PICUMS were applied before ICU and hospital discharge. Analysis of covariance, Quade´s test, and Fisher's exact test compared groups. Partial correlations were analized between the MRC-SS and PICUMS with clinical variables. Regression models identified the predictors of hospital length of stay. The ROC curve verified the PICUMS related to ICUAW. Significance was set as P <.05. 25 individuals were included in the COVID-19 group and 23 in the non-COVID-19 group. No between-groups difference was observed in MRC-SS and PICUMS at discharge from ICU or hospital. The MRC-SS and PICUMS at ICU discharge predicted the length of hospital stay in the COVID-19 group. The PICUMS cut-off related to ICUAW was 18. Muscle strength, mobility, and ICUAW are similar between COVID-19 and non-COVID-19. However, muscle strength and mobility at ICU discharge are associated with the length of stay during COVID-19. A PICUMS<18 at ICU discharge may indicate impaired physical functioning due to ICUAW.

Background and aims: Only one cohort study exists on the incidence of the risk of malnutrition (RM) in older adults, though numerous cross-sectional reports, identified several risk factors associated with the prevalence and incidence of this condition. However, alterations in body composition and impaired physical performance as exposition variables of RM have not been explored. This study assessed the incidence of RM and determined its association with excess fat mass, low total lean tissue, gait speed, and handgrip strength as exposition variables for RM in community-dwelling older adults. Methods: This is a secondary analysis of older adults (≥60 years) derived from the study "Frailty, dynapenia, and sarcopenia in Mexican adults (FraDySMex)", a prospective cohort project conducted from 2014 to 2019 in Mexico City. At baseline, volunteers underwent body composition analysis and physical performance tests. Several covariates were identified through comprehensive geriatric assessment. At baseline and follow-up, RM was assessed using the long form of the mini nutritional assessment (MNA-LF) scale. Associations between the exposition variables and RM were assessed by multiple logistic regression. Results: The cohort included 241 subjects. The average age was 75.6 ± 7.8 years, and 83.4% were women. The mean follow-up period was 4.1 years, during which 28.6% of subjects developed RM. This condition was less likely to occur in those with an excess fat mass, even after adjusting for several covariates. Regarding total lean tissue, the unadjusted model showed that RM was more likely to occur in men and women with a low TLT by the TLTI classification, compared to the normal group. However, after adjusting for several covariates (models 1 and 2), the association lost significance. Results on the association between gait speed and RM showed that this condition was also more likely to occur in subjects with low gait speed, according to both the unadjusted and adjusted models. Similar results were found for RM in relation to low handgrip strength; however, after adjusting for the associated covariates, models 1 and 2 no longer reached the level of significance. Conclusions: RM diagnosed by MNA-LF was significantly less likely to occur among subjects with excess fat mass, and a significant association emerged between low gait speed and RM after 4.1 years of follow-up in these community-dwelling older adults. These results confirm the association between some alterations of body composition and impaired physical performance with the risk of malnutrition and highlight that excess fat mass and low gait speed precede the risk of malnutrition, not vice versa.

Objectives: The aim of the study was to determine the care burden and influencing factors of patients receiving home health care. Materials and Methods: The study was cross-sectional descriptive and was conducted with patients who benefited from a tertiary hospital's home health care unit. A 25-question demographic data questionnaire was prepared by the researchers by scanning the literature, and the BARTHEL daily living activities index was applied to the patients. Results: A total of 416 people participated in the study, 34.86% (n=145) of whom were male, and 65.14% (n=271) were female. According to the Barthel daily living activities index, 43.75% (n=182) of the patients were entirely dependent, 38.46% (n=160) were severely dependent, and their average score was 34.14±29.27. No significant relationship was found between the gender of the caregiver, closeness with the patient, education level of the patient and the perceived burden of care. On the other hand, a significant relationship was found between the education level of the caregiver, the profession, the dependency degree of the patient, and the perceived burden of care (p=0.001, p=0.031, and p<0.001, respectively). Conclusion: To reduce the care burden of caregivers, it is necessary to increase the quality and accessibility of home healthcare services, provide education and support for patients and caregivers, and take measures to maintain and improve patients' independence.

This study aimed to evaluate the level of physical activity, functional capacity (FC), and flexibility of young adults before and ten months after joining a physical exercise program in the Brazilian Army. This was a prospective cohort study. The level of physical activity was assessed using the International Physical Activity Questionnaire (IPAQ), FC using the Cooper Test, and flexibility using the Wells bench. Sample (n = 198; 18±0.27 years) with a body mass index (BMI) of 23.23±3.84 kg/m². After ten months of admission to the Brazilian Army, there was a reduction in the prevalence of sedentary lifestyle (33→ 28%) and FC (2,982±243.61 → 3,117±192.87 m), without change in flexibility (27.31±7.39 → 27.52±7.40 cm). There was a large effect size on BMI, waist-hip ratio (WHR), and flexibility. In short, inclusion in a physical exercise program in the Brazilian Army increased FC and reduced the WHR of young recruits. [ABSTRACT FROM AUTHOR]

Background and Purpose: The Short Physical Performance Battery (SPPB) is widely used for older adults since it has a high level of validity, reliability, and responsiveness in measuring function in this population. However, only a few studies of diagnostic accuracy have assessed SPPB capacity in detecting frailty and prefrailty by estimating more detailed measurement properties. Thus, the present study aimed to evaluate the SPPB's diagnostic accuracy in detecting frailty and prefrailty, in addition to identifying cut-off points for walking time and chair stand time. Methods: This is a cross-sectional study composed of 786 community-dwelling older adults 60 years or older, in which sociodemographic and anthropometric data, frailty phenotype, and total SPPB score, as well as walking time and chair stand time, were assessed. Analysis of a receiver operating characteristic curve was performed to identify the cut-off point, sensitivity, and specificity in the total SPPB score, as well as the walking time and chair stand time for frailty and prefrailty screening. Accuracy and positive and negative predictive values were subsequently calculated. Results and Discussion: The cut-off points identified for the total SPPB score, walking time, and chair stand time were 9 points or less (accuracy of 72.6%), 5 seconds or less, and 13 seconds or less, respectively, for frailty screening and 11 points or less (accuracy of 58.7%), 4 seconds or less, and 10 seconds or less, respectively, for prefrailty screening. The walking time showed greater frailty discriminatory capacity compared with the chair stand time (effect size = 1.24 vs 0.64; sensitivity = 69% vs 59%; and specificity = 84% vs 75%). Conclusions: The total SPPB score has good diagnostic accuracy to discriminate between nonfrail and frail older adults using a cut-off point of 9 or less, being better to identify the true negatives (older adults who are not frail). Although the SPPB's diagnostic accuracy measures for detecting prefrailty were low to moderate, this instrument can help in screening prefrail older adults from the cutoff point of 11 or less in the total SPPB score. Identification of prefrail older adults enables implementing early treatment in this target audience and can prevent their advance to frailty. [ABSTRACT FROM AUTHOR]

BACKGROUND: Firefighting is a physiologically demanding occupation and there is a need to evaluate physical and fitness characteristics that are related to attenuated physiological stress during fireground tasks. Previous studies have not measured associations between heart rate responses during simulated fireground tasks with a standardized work rate. OBJECTIVE: The purpose of this study was to examine associations between heart rate during a standardized pace simulated fireground test (SFGT) and heart rate recovery and variability following the SFGT. In addition, this study sought to evaluate associations between heart rate measures versus physical and fitness characteristics in structural firefighter recruits. METHODS: Twenty-one fire academy recruits performed a standardized pace SFGT while mean heart rate reserve (HRRes) during the SFGT, change in heart rate variability from rest to post-SFGT (LnRMSSDRest-Post), and 60-second post-SFGT heart rate recovery (HRR60) were measured. Regression analyses were conducted between HRRes, LnRMSSDRest-Post and HRR60 and between heart rate measures versus physical and fitness characteristics while accounting for differences in SFGT completion time. RESULTS: HRRes was associated with LnRMSSDRest-Post, but not HRR60. Height and pull-ups explained most of the variance in HRRes, height explained most of the variance in LnRMSSDRest-Post and push-ups and 1.5-mile run explained most of the variance in HRR60. CONCLUSION: Greater cardiovascular stress during fireground tasks is associated with greater depression of post-SFGT heart rate variability, but not heart rate recovery. Physical and fitness characteristics are important to consider in relation to firefighters' ability to cope with physical stress on the fireground. [ABSTRACT FROM AUTHOR]

Individuals diagnosed with systemic arterial hypertension (SAH) are considered risk groups for COVID-19 severity. This study assessed differences in cardiac autonomic function (CAF) and functional capacity (FC) in SAH individuals without COVID-19 infection compared to SAH individuals post-COVID-19. Participants comprised 40 SAH individuals aged 31 to 80 years old, grouped as SAH with COVID-19 (G1; n = 21) and SAH without COVID-19 (G2; n = 19). CAF was assessed via heart rate variability (HRV), measuring R–R intervals during a 10-min supine period. Four HRV indices were analyzed through symbolic analysis: 0V%, 1V%, 2LV%, and 2UV%. FC assessment was performed by a 6-min walk test (6MWT). G1 and G2 showed no significant differences in terms of age, anthropometric parameters, clinical presentation, and medication use. G2 exhibited superior 6MWT performance, covering more distance (522 ± 78 vs. 465 ± 59 m, p < 0.05). Specifically, G2 demonstrated a moderate positive correlation between 6MWT and the 2LV% index (r = 0.58; p < 0.05). Shorter walking distances were observed during 6MWT in SAH individuals post-COVID-19. However, the study did not find impaired cardiac autonomic function in SAH individuals post-COVID-19 compared to those without. This suggests that while COVID-19 impacted FC, CAF remained relatively stable in this population. [ABSTRACT FROM AUTHOR]

BACKGROUND: Previous literature suggests that transversus abdominis (TrA) activation is diminished in chronic low back pain (cLBP) subjects compared to healthy subjects in less-functional positions. However, few studies have investigated the effects of upright functional movement on TrA activation in cLBP individuals. OBJECTIVE: This pilot study aimed to compare TrA activation characteristics in healthy and cLBP subjects during the movement of double leg standing (DLS) to single leg standing (SLS) and to a 30 ∘ single leg quarter squat (QSLS). METHODS: TrA activation was determined by the percentage change in TrA thickness from DLS to SLS and DLS to QSLS. TrA thickness was measured in 14 healthy and 14 cLBP participants using ultrasound imaging with a probe holder at 20 mm and 30 mm from the fascia conjunction point. RESULTS: At both measurement points (20 and 30 mm), there were no significant main effects of body sides, lower limb movements and the interactions between them on TrA activations between the healthy and cLBP participants even after covariates were adjusted for (all p > 0.05). CONCLUSIONS: Results from this study suggest the evaluation of TrA activation during upright functional movements as part of an assessment for cLBP management may not be suggested.

Objectives: This study aimed to investigate the association between ankle torque and performance-based tests, self-reported pain, and physical function in patients with knee osteoarthritis (OA). Patients and methods: The cross-sectional study was conducted with 39 individuals (24 females, 15 males; mean age: 57.3±6.2 years; range, 40 to 65 years) with knee OA between January 2014 and July 2015. Ankle torque was determined using an isokinetic dynamometer. The 40-m fast-paced walk test and a stair climb test were used to assess functional performance. Self-reported pain and physical function were assessed using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Pearson's correlation coefficients were calculated to test correlations between the dependent variables (40-m fast-paced walk test, stair climb test, WOMAC pain and physical function domains, sex, age, body mass index, and radiologic evidence of OA) and the independent variables (mean plantar flexor torque and dorsiflexor peak torque). A multiple linear regression analysis was applied to quantify the association between the dependent and independent variables. Results: Dorsiflexor and plantar flexor peak torques in the concentric and eccentric modes were negatively correlated with the 40-m fast-paced walk and stair climb tests (r=-0.33 to -0.51, p=0.05). A negative correlation was found between concentric plantar flexor torque and the WOMAC physical function score (r=-0.35, p=0.03). No correlation was found between ankle torques and the WOMAC pain score (p>0.05). The multiple linear regression analysis showed that the eccentric plantar flexor and dorsiflexor torques were significantly associated with the stair climb test (β=-0.001, 95% confidence interval [CI]: -0.001 to 0.000, p=0.03, and β=-0.002, 95% CI: -0.004 to 0.000, p=0.05, respectively). No significant associations were found between concentric plantar flexor and dorsiflexor torques and the stair climb test (p>0.05). No significant associations were found between the ankle torques and the 40-m fast-paced walk test and WOMAC physical function (p>0.05). Conclusion: Ankle torque plays an important role in functional performance. Thus, ankle torque deficit, especially eccentric plantar flexor and dorsiflexor torques, may exert a negative influence on stair climbing performance in patients with knee osteoarthritis.

• The environment determines the mental and physical health of the older adults. • Better environmental characteristics decrease the chances of functional limitation. • Poor safety increases the chances of limitations in mobility and muscle strength. • Better streets/sidewalks decrease 57% the likelihood of cognitive impairment. It is important to identify the association between characteristics of the neighborhood environment, cognitive impairment and functional limitations to organize early and effective intervention strategies. A cross-sectional survey of 308 community-dwelling older adults was conducted. Logistic Regression analyses were performed to verify the associations between self-perceived characteristics of the neighborhood environment (Neighborhood Environment Walkability Scale), cognitive impairment (Mini-Mental State Examination) and functional limitations (mobility, lower limb muscle strength and balance). Significant negative associations were observed: (1) better infrastructure, traffic and safety and mobility limitation; (2) better infrastructure and muscle weakness; (3) better safety and balance limitation; and (4) better streets/sidewalks and cognitive impairment. On the other hand, positive associations were observed between poor safety with mobility limitation and muscle weakness. Our findings contribute to greater knowledge about neighborhood characteristics regarding mental and physical health in community-dwelling older adults. [ABSTRACT FROM AUTHOR]

Objective: Currently, little is known about the long-term outcomes of COVID-19 in the pediatric population. The aim of this study was to investigate the long-term clinical outcomes of pediatric patients hospitalized with COVID-19. Methods: This was a prospective cohort study involving unvaccinated children and adolescents admitted to a tertiary hospital in southern Brazil with a COVID-19 diagnosis. Data were collected from electronic medical records for one year after the diagnosis. Results: A total of 66 children were included: the median age was 2.9 years; 63.6% were male; and 48.5% were under 2 years of age. Over 70% had at least one comorbidity prior to the COVID-19 diagnosis. During the one-year follow-up period, 59.1% of the children revisited the emergency department, 50% required readmission, and 15.2% died. Younger children with longer hospital stays were found to be at greater risk of readmission. Having cancer and impaired functionality were found to increase the risk of death within one year. Conclusions: Our findings indicate that most children hospitalized with COVID-19 have comorbidities. Younger age at admission and a longer hospital stay seem to be risk factors for readmission. In addition, the presence of cancer and impaired functionality are apparently associated with the poor outcome of death within the first year after the diagnosis of COVID-19. [ABSTRACT FROM AUTHOR]

ObjectiveTo link scores from 2 condition-specific measures for chronic low back pain (CLBP), the Oswestry Disability Index (ODI) and the Roland-Morris Disability Questionnaire (RMDQ), to Patient Reported Outcomes Measurement Information System (PROMIS) physical function, pain interference, and pain intensity scores.DesignOrdinary least squares regression analyses of existing data to link the PROMIS scores with the ODI and RMDQ.SettingNot applicable.ParticipantsSamples of adults with CLBP (N=2279) obtained from the Center for Excellence in Research for Complementary and Integrative Health (CERC) Study (n=1677), the Assessment of Chiropractic Treatment for Low Back Pain and Smoking Cessation in Military Active Duty Personnel (ACT) (n=384), and the pain subsample of the PROMIS 1 Wave 2 Pain and Depression study (PROMIS 1 W2) (n=218).InterventionsNot applicable.Main outcome measuresPROMIS physical function, pain interference, and pain intensity (CERC, ACT, and PROMIS 1 W2), ODI (CERC and PROMIS 1 W2), and RMDQ (ACT and PROMIS 1 W2).ResultsIn predicting PROMIS scores, the ODI model R2 values ranged from 0.26-0.56 and the RMDQ model R2 values ranged from 0.13-0.50. ODI and RMDQ models were the least precise in predicting the PROMIS pain intensity score (R2 value range, 0.13-0.41) relative to the other PROMIS scores. Models with the 3 PROMIS scores as predictors yielded R2 values ranging from 0.64-0.68 and 0.46-0.58 for the ODI and RMDQ, respectively. Models using combined data from 2 studies (ie, PROMIS 1 W2 and ACT, or PROMIS 1 W2 and CERC) tended to be more precise than models using only a single study sample.ConclusionsModel results reported here can be used to translate PROMIS physical function, pain interference, and pain intensity scores to and from the ODI and RMDQ. The empirical linkages can facilitate comparisons across CLBP interventions and broaden interpretation of study results.

Mitochondrial DNA (mtDNA) quality and quantity relate to two hallmarks of aging-genomic instability and mitochondrial dysfunction. Physical performance relies on mitochondrial integrity and declines with age, yet the interactions between mtDNA quantity, quality, and physical performance are unclear. Using a validated digital PCR assay specific for mtDNA deletions, we tested the hypothesis that skeletal muscle mtDNA deletion mutation frequency (i.e., a measure of mtDNA quality) or mtDNA copy number predicts physical performance in older adults. Total DNA was isolated from vastus lateralis muscle biopsies and used to quantitate mtDNA copy number and mtDNA deletion frequency by digital PCR. The biopsies were obtained from a cross-sectional cohort of 53 adults aged 50 to 86 years. Before the biopsy procedure, physical performance measurements were collected, including VO2max, modified physical performance test score, 6-min walk distance, gait speed, grip strength, and total lean and leg mass. Linear regression models were used to evaluate the relationships between age, sex, and the outcomes. We found that mtDNA deletion mutation frequency increased exponentially with advancing age. On average from ages 50 to 86, deletion frequency increased from 0.008 to 0.15%, an 18-fold increase. Females may have lower deletion frequencies than males at older ages. We also measured declines in VO2max and mtDNA copy number with age in both sexes. The mtDNA deletion frequency measured from single skeletal muscle biopsies predicted 13.3% of the variation in VO2max. Copy number explained 22.6% of the variation in mtDNA deletion frequency and 10.4% of the lean mass variation. We found predictive relationships between age, mtDNA deletion mutation frequency, mtDNA copy number, and physical performance. These data are consistent with a role for mitochondrial function and genome integrity in maintaining physical performance with age. Analyses of mtDNA quality and quantity in larger cohorts and longitudinal studies could extend our understanding of the importance of mitochondrial DNA in human aging and longevity.

ObjectivePost-traumatic stress disorder (PTSD) is common in Veterans. Symptoms can perpetuate into late life, negatively impacting physical and mental health. Exercise and social support are beneficial in treating anxiety disorders such as PTSD in the general population, although less is known about the impact on Veterans who have lived with PTSD for decades. This study assessed associations between social connectedness, physical function and self-reported change in PTSD symptoms among older Veterans specifically participating in Gerofit.DesignProspective clinical intervention.SettingTwelve sites of Veterans Affairs (VA) Gerofit exercise program across the United States.ParticipantsThree hundred and twenty one older Veteran Gerofit participants (mean age = 74) completed physical assessments and questionnaires regarding physical and emotional symptoms and their experience.MeasurementsMeasures of physical function, including 30-second chair stands, 10-m and 6-min walk were assessed at baseline and 3 months; change in PTSD symptoms based on the Diagnostic Statistical Manual-5 (DSM-5) assessed by a self-report questionnaire; and social connection measured by the Relatedness Subscale of the Psychological Need Satisfaction in Exercise scale (PNSE) were evaluated after 3 months of participation in Gerofit.ResultsNinety five (29.6%) Veterans reported PTSD. Significant improvement was noted in self-rated PTSD symptoms at 3 months (P

BACKGROUND: Research supports that moderate-to-vigorous intensity physical activity (MVPA) is key to prolonged health and function. Among older adults, substantial changes to MVPA may be infeasible, thus a growing literature suggests a shift in focus to whole-day activity patterns. METHODS: With data from 795 older adults aged 65-100 in the Adult Changes in Thought Activity Monitoring study, we used linear regression to estimate associations between ActiGraph and activPAL measured activity patterns - including light intensity physical activity, steps, standing, and sedentary behaviors - and physical function as measured by a short Performance-based Physical Function (sPPF) score (range 0-12), a composite score based on three standardized physical performance tasks: gait speed, timed chair stands, and grip strength. We examined whether relationships persisted when controlling for MVPA or differed across age, gender, or quartiles of MVPA. RESULTS: In models unadjusted for MVPA, a 1-standard deviation (SD) increment of daily sitting (1.9 h more), mean sitting bout duration (8 min longer average), or time spent in sedentary activity (1.6 h more) was associated with ~ 0.3-0.4 points lower mean sPPF score (all p

Abstract Aim This study aimed to predict the functional performance of patients with chronic obstructive pulmonary disease by clarifying the relationship among disease severity, uncertainty, social support, symptom experience, coping, and functional performance. Design A model‐testing design was used. Methods The subjects of this study were outpatients with chronic obstructive pulmonary disease who visited the respiratory clinic of a general hospital in Seoul, Korea. The data were collected using validated instruments from July 2018 to April 2019, of which 202 questionnaires in total were used for data analysis. Collected data were analysed by using IBM SPSS v27.0 and Mplus 8.0. Results The severity of the disease, uncertainty, and symptom experience should be reduced to improve the functional performance of chronic obstructive pulmonary disease patients. Furthermore, reduced uncertainty can improve functional performance by reducing symptom experience. Nursing interventions for the improvement of pulmonary function and reduction of symptom experience should be developed.

Objectives: This study aimed to assess the feasibility of the home-based kyphosis-specific exercises among Chinese older adults with different exercise habits and explore its potential effects on reducing the kyphosis angle and improving physical performance. Methods: A single-group, pre-and post-test design was conducted according to CONSORT 2010 statement: extension for pilot and feasibility trials. A total of 20 participants aged ≥60 with thoracic hyperkyphosis and rehabilitation potential were recruited from four local communities in Wuhan, China. Participants underwent a six-week home-based kyphosis-specific exercises intervention that included warm-up, muscle strengthens, spinal alignment, spinal mobility and flexibility, and cool down five sections (22 exercises). The intervention involved seven 1-h group classes and 35 times daily home practice with identical content. At pre- and post-intervention, the participants' kyphosis angle in two standing postures, static balance, dynamic balance, cardiopulmonary function, dynamic gait assessment, pain, and self-image were assessed and compared. Feasibility was assessed by group class attendance, home practice adherence, and participant evaluations. Results: All participants completed group classes and >75% home practice. Post-intervention, the participant’s kyphosis angle in relaxed and best-standing postures was changed by −12.0° (−15.5°, −4.0°) (Z = − 3.98, P

The jaw sensorimotor system has functional relationships with other parts of the body through neuroanatomical and biomechanical interactions. The aim of this study was to examine the effects of different jaw positions on upper extremity performance, core endurance, and postural stability. This cross-sectional study included 49 healthy young adults aged 18-28 years. Upper extremity performance was evaluated using the push-up test, core endurance was evaluated using the McGill’s Trunk Flexion and Extension Test and postural stability was evaluated using the Balance Error Scoring System. All assessments were made with resting jaw and clenching jaw positions. There was no significant difference in the Push-up test and Balance Error Scoring System scores in different jaw positions (p>0.05). The Mcgill trunk flexion test and extension test performance were found to be better in the clenched jaw position (p=0.017, p=0.035, respectively). The results of this study showed that jaw clenching increases core endurance time. This result should be taken into account when planning an evaluation and rehabilitation program for the core area.

INTRODUCTION: Over half of all people with lower limb amputation (LLA) experience at least one fall annually. Furthermore, the majority of LLAs result from dysvascular health complications, contributing to balance deficits. However, fall-related research specific to dysvascular LLA remains limited. OBJECTIVE: To characterize falls among adults with dysvascular LLA, using an existing Fall-Type Classification Framework and to describe the functional characteristics of participants across the framework categories. DESIGN: Secondary data analysis from two randomized controlled trials. SETTING: Outpatient setting. PARTICIPANTS: People (n = 69) 6 months to 5 years from dysvascular lower extremity amputation, who were ≥50 years of age and independently ambulatory using a prosthesis. INTERVENTION: None. OUTCOME: Descriptions of self-reported falls were collected on a weekly basis for 12 weeks, and analyzed using an existing Fall-Type Classification Framework. Fall frequencies, estimated count, and estimated proportions were compared across all framework categories, with 95% confidence intervals. Functional measures (Timed Up and Go, Two Minute Walk, Five Meter Walk, and average step count) were collected, and averages for each participant who experienced a fall were calculated. RESULTS: Thirty participants (43.5%) reported 42 falls within 12 weeks. A variety of fall types were described. Incidence of falls was highest for intrinsic destabilization sources, from incorrect weight shift patterns during transfer activities. CONCLUSION: Patients with dysvascular LLAs experience a variety of fall types. The high frequency of intrinsically sourced, incorrect weight-shift falls during transfer activities emphasizes the need to focus rehabilitation efforts on improving postural control in patients with dysvascular LLAs during activities such as reaching, turning, and transferring.

Latinos in the US live significantly longer than non-Latino whites, but spend more years disabled. Differentials in socioeconomic status account for part, but not all, of the difference in older age disability between Latinos and whites. We hypothesize that a factor often ignored in the literature-the fact that Latinos, on average, have more physically strenuous jobs than non-Latino whites-contributes to the higher Latino risk of functional limitations at older ages. We use longitudinal data from the 1998-2014 Health and Retirement Study (HRS) comprising 17,297 respondents. Compared to US-born whites, Latinos, especially Latino immigrants, report substantially higher levels of physical effort at work. Latino-black differences are much smaller than Latino-white differences. As hypothesized, physical work effort is strongly related to functional limitations. However, differentials in physical work effort for Latinos and whites in their fifties and early sixties are weakly related to Latino-white differentials in FL at later ages.

PurposeThe current number of breast cancer survivors (BCS) in the United States is approximately 3.8 million, and this number is further expected to increase with improvement in treatments. Survivorship care plans (SCPs) are patient-centered tools that are designed to meet cancer survivors' informational needs about their treatment history, recommended health care, and health maintenance. However, the data on SCP benefits remain uncertain, especially in low-income and racial and ethnic minority cancer survivors. Patient navigation is an effective intervention to improve patient adherence and experience of interdisciplinary breast cancer treatment.ObjectivesThis study sought to understand the role of lay patient navigators (LPN) in survivorship care planning for BCS in safety-net settings.MethodsThis study is a mixed methods pilot randomized clinical trial to understand the role of patient navigation in cancer survivorship care planning in a public hospital. We invited BCS who had completed active breast cancer treatment within 5 years. LPNs discussed survivorship care planning and survivorship care-related issues with BCS in the intervention arm over a 6-month intervention period and accompanied patients to their primary care appointment. LPNs also encouraged survivors to discuss health care issues with oncology and primary care providers. The primary objective was to assess BCS' health-related quality of life (HRQOL). The secondary objectives were self-efficacy and implementation. We assessed implementation with 45-60-min semi-structured interviews with 15 BCS recruited from the intervention arm and 60-min focus groups with the oncologists and separately with LPNs.ResultsWe enrolled 40 patients, 20 randomized to usual care and 20 randomized to LPN navigation. We did not find a statistically significant difference between the two arms in HRQOL. There was also no difference in self-efficacy between the two arms. Qualitative analysis identified implementation barriers to intervention that may have contributed to less effective intervention.Implications for cancer survivorsFuture survivorship care planning interventions need to consider: Cancer survivors' needs and preferences, the need for dedicated resources, and the role of electronic health records in survivorship care plan delivery.

BackgroundSedentary behavior (SB) is linked to negative health outcomes in older adults. Most studies use summary values, e.g., total sedentary minutes/day. Diurnal timing of SB accumulation may further elucidate SB-health associations.MethodsSix thousand two hundred four US women (mean age = 79 ± 7; 50% White, 34% African-American) wore accelerometers for 7-days at baseline, yielding 41,356 person-days with > 600 min/day of data. Annual follow-up assessments of health, including physical functioning, were collected from participants for 6 years. A novel two-phase clustering procedure discriminated participants' diurnal SB patterns: phase I grouped day-level SB trajectories using longitudinal k-means; phase II determined diurnal SB patterns based on proportion of phase I trajectories using hierarchical clustering. Mixed models tested associations between SB patterns and longitudinal physical functioning, adjusted for covariates including total sedentary time. Effect modification by moderate-vigorous-physical activity (MVPA) was tested.ResultsFour diurnal SB patterns were identified: p1 = high-SB-throughout-the-day; p2 = moderate-SB-with-lower-morning-SB; p3 = moderate-SB-with-higher-morning-SB; p4 = low-SB-throughout-the-day. High MVPA mitigated physical functioning decline and correlated with better baseline and 6-year trajectory of physical functioning across patterns. In low MVPA, p2 had worse 6-year physical functioning decline compared to p1 and p4. In high MVPA, p2 had similar 6-year physical functioning decline compared to p1, p3, and p4.ConclusionsIn a large cohort of older women, diurnal SB patterns were associated with rates of physical functioning decline, independent of total sedentary time. In particular, we identified a specific diurnal SB subtype defined by less SB earlier and more SB later in the day, which had the steepest decline in physical functioning among participants with low baseline MVPA. Thus, diurnal timing of SB, complementary to total sedentary time and MVPA, may offer additional insights into associations between SB and physical health, and provide physicians with early warning of patients at high-risk of physical function decline.

This study targeted elderly women over 60 years old (109 persons), divided them into an exercise group and a control group, and implemented a 12-week physical activity program for the exercise group. Body composition, muscle, blood tests, depression, quality of life (QoL), nutritional status, and physical strength were compared and analyzed. The physical activity program was organized through a consultative body of experts, was performed for about 60 min each time in the type and order of exercise appropriate for elderly women, and consisted of a combination of exercise using a band, gymnastics, and stretching. Changes in the muscle index and muscle mass before and after the program were selected as the primary efficacy evaluations. In the exercise group, waist circumference significantly decreased, and the muscle index significantly increased compared to the control group. The number of subjects who showed sarcopenia with a muscle index of 5.4 or less in the exercise group significantly decreased from 22 (38.6%) before program implementation to 13 (22.8%). According to the results of secondary effectiveness evaluation, high-density lipoprotein cholesterol and apolipoprotein (Apo) A were significantly increased in the exercise group compared to the control group, and Apo B, triglyceride, and c-reactive protein showed a significant decrease. Regular physical activity is very important for improving the health and QoL of elderly women, and as a result of applying a customized program, effects such as increased muscle index, improvement of sarcopenia, and improvement of blood lipid status were confirmed. Therefore, it is believed that the physical activity program developed through this study can be applied as a community program for elderly women.

This study aims to determine whether post-hospitalization psychological distress is associated with exercise capacity, physical function and health status in COVID-19 survivors. In this observational study, hospitalized COVID patients were included and divided into two groups according to the mental component summary subscale of the 12-item Short-Form Health Survey. Patients with a score ≤ 45 were included in the psychological distress group, and patients with a score > 45 were included in the non-psychological distress group. The main variables were exercise capacity, physical function, and health status. Patients were evaluated at discharge, 3 months, and at 6 months follow-up. Finally, a total of 60 patients were included in the study. Significant differences were found in exercise capacity, physical function, and health status (p < 0.05), with worse results in the group with psychological distress at discharge and 3 months follow-up. At 6 months after discharge, COVID patients with psychological distress exhibited worse results in exercise capacity, physical function, and health status, being significant exercise capacity and physical function (p < 0.05). It can be concluded that COVID patients with psychological distress at hospital discharge reported worse exercise capacity, physical function and health status at hospital discharge, 3 months and 6 months follow-up.

ABSTRACT Objective: Currently, little is known about the long-term outcomes of COVID-19 in the pediatric population. The aim of this study was to investigate the long-term clinical outcomes of pediatric patients hospitalized with COVID-19. Methods: This was a prospective cohort study involving unvaccinated children and adolescents admitted to a tertiary hospital in southern Brazil with a COVID-19 diagnosis. Data were collected from electronic medical records for one year after the diagnosis. Results: A total of 66 children were included: the median age was 2.9 years; 63.6% were male; and 48.5% were under 2 years of age. Over 70% had at least one comorbidity prior to the COVID-19 diagnosis. During the one-year follow-up period, 59.1% of the children revisited the emergency department, 50% required readmission, and 15.2% died. Younger children with longer hospital stays were found to be at greater risk of readmission. Having cancer and impaired functionality were found to increase the risk of death within one year. Conclusions: Our findings indicate that most children hospitalized with COVID-19 have comorbidities. Younger age at admission and a longer hospital stay seem to be risk factors for readmission. In addition, the presence of cancer and impaired functionality are apparently associated with the poor outcome of death within the first year after the diagnosis of COVID-19.

The aims of this study were (1) to describe and examine differences in change of direction (COD) performance and the magnitude of asymmetries in para‐footballers with cerebral palsy (CP) and controls and (2) to evaluate the association between COD outcomes and linear sprint performance. Twenty‐eight international para‐footballers with CP and thirty‐nine non‐impaired football players (control group) participated in this study. All participants completed a 10‐m sprint and two attempts of the 505 COD test with the dominant and non‐dominant leg. The COD deficit was calculated using the difference between the 505 test and the 10‐m sprint time, while the asymmetry index was determined by comparing each leg's completion time and COD deficit. Players across groups showed interlimb asymmetries between the dominant and non‐dominant legs in COD outcomes and deficit (p < 0.05, dg = −0.40 to −1.46), although these asymmetries imbalance were not significantly different between the sexes with and without impairment. Males with CP exhibited a faster directional COD speed and a shorter COD deficit than their female counterparts (p < 0.01, dg = −1.68 to −2.53). Similarly, the control group had faster scores than the CP groups of the same sex (p < 0.05, dg = 0.53 to 3.78). Lastly, the female CP group and male control groups showed a significant association between sprint and the COD deficit in the dominant leg (p < 0.05, r = −0.58 to 0.65). Therefore, the use of directional dominance, the COD deficit, and asymmetry outcomes could be helpful for classification purposes to assess the impact of the impairment on sport‐specific activity testing according to sex.

Background: Life-space mobility is defined as the size of the area in which a person moves about within a specified period of time. Our study aimed to characterize life-space mobility, identify factors associated with its course, and detect typical trajectories in the first year after ischemic stroke. Methods: MOBITEC-Stroke (ISRCTN85999967; 13/08/2020) was a cohort study with assessments performed 3, 6, 9 and 12 months after stroke onset. We applied linear mixed effects models (LMMs) with life-space mobility (Life-Space Assessment; LSA) as outcome and time point, sex, age, pre-stroke mobility limitation, stroke severity (National Institutes of Health Stroke Scale; NIHSS), modified Rankin Scale, comorbidities, neighborhood characteristics, availability of a car, Falls Efficacy Scale-International (FES-I), and lower extremity physical function (log-transformed timed up-and-go; TUG) as independent variables. We elucidated typical trajectories of LSA by latent class growth analysis (LCGA) and performed univariate tests for differences between classes. Results: In 59 participants (mean age 71.6, SD 10.0 years; 33.9% women), mean LSA at 3 months was 69.3 (SD 27.3). LMMs revealed evidence (p ≤ 0.05) that pre-stroke mobility limitation, NIHSS, comorbidities, and FES-I were independently associated with the course of LSA; there was no evidence for a significant effect of time point. LCGA revealed three classes: "low stable", "average stable", and "high increasing". Classes differed with regard to LSA starting value, pre-stroke mobility limitation, FES-I, and log-transformed TUG time. Conclusion: Routinely assessing LSA starting value, pre-stroke mobility limitation, and FES-I may help clinicians identify patients at increased risk of failure to improve LSA.

BACKGROUND: A stringent systematic review of population-based observational studies focusing on the physical health of self-employed individuals as a basis for the development of targeted prevention strategies is lacking. OBJECTIVE: We aimed to systematically evaluate all the studies of good quality that compared the occurrence of chronic physical disorders in self-employed individuals with that of employees. METHODS: We searched three major medical databases (MEDLINE, Web of Science, Embase) following the Cochrane guidelines. The quality of the studies was rated based on the slightly modified validated assessment tool that was developed by Hoy et al. RESULTS: We included 16 population-based studies of good quality, with data from 15,369,964 participants in total. The two longitudinal evaluations of Swedish national registers with the longest follow-up periods showed increased cardiovascular mortality and incidence estimates of cardiovascular disease in self-employed individuals compared with those of white-collar (i.e., nonmanual) employees but decreased risk estimates compared with those of blue-collar (i.e., manual) workers. The results of the shorter cohort studies were heterogeneous. In cross-sectional studies, prevalence estimates for musculoskeletal, respiratory and malignant diseases were higher among self-employed individuals than among employees. CONCLUSION: The long-term cardiovascular disease risk and mortality of self-employed individuals seemed to be higher than those of white-collar employees but lower than those of blue-collar employees. As a basis for targeted prevention strategies, further longitudinal studies in different settings are required to better understand the development of physical health disorders for specific self-employment categories such as sole proprietors, small entrepreneurs, family businesses and others.

Background and Aims: Extended hospitalization due to coronavirus disease 2019 (COVID‐19) is associated with residual musculoskeletal and functional deficits lasting even 6 months after discharge; therefore, it is crucial that post‐hospitalized patients are promptly assessed. The aim of this study was to identify post‐COVID‐19 patients' functional status and quality of life, as well as to investigate their inter‐relatedness 2–3 weeks after hospital discharge. Methods: The study included 39 post‐COVID‐19 patients previously hospitalized in the Clinic for Infectious Diseases at the University Clinical Center of Kosovo (UCCK) from August to December 2021. Physiotherapeutic assessment encompassed socio‐demographic and clinical data including Short Physical Performance Battery (SPPB) for physical functional performance, hand grip strength, 6‐min Walk Test (6MWT) for aerobic capacity and endurance, EuroQol 5‐Dimension 5‐Level (EQ‐5D‐5L) for quality of life, Visual Analogue Scale (VAS) for pain, Borg CR10 for dyspnea, peripheral oxygen saturation and heart rate. Descriptive statistics, Pearson correlation, and multiple linear regression analysis were utilized for data processing. Results: The median (interquartile range [IQR]) for Borg CR10, VAS pain scale, total SPPB, grip strength, and 6MWT were 1 (0–3), 3 (1–6), 9 (8–10), 30.5 (23.2–43.5) kg, 344.5 (312.7–381.7) m respectively, while the mean (SD) for EQ‐5D‐5L index value was 0.7 (0.2). The strongest and most significant correlation was depicted between SPPB total score and its subscales, followed by correlation with EQ‐5D‐5L (r = 0.719, p < 0.001), grip strength (r = 0.612 p < 0.001), Borg CR10 (r = −0.515, p = 0.001), 6MWT (r = 0.416, p = 0.02), and VAS scale (r = −0.343, p = 0.03). Using the multiple regression analysis, the grip strength, Borg‐CR10, and 6MWT were found to be strongly predictive of SPPB total score. Conclusion: In post‐COVID‐19 patients' functional status and quality of life were impaired 2–3 weeks following hospitalization. SPPB showed the most frequent and significant correlation with other variables, hence it should be considered as one of the primary screening tools. Keypoints: Based on the heterogeneity of symptom presentation and clinical course, there is a need to carefully monitor for signs and symptoms in individuals with postcoronavirus disease 2019 (COVID‐19) conditions, especially in previously hospitalized patients.There are no established core outcome measures to be applied in the framework of physical therapy for post‐COVID‐19 conditions.In our study, post‐COVID‐19 patients had impaired functional status and quality of life, as early as two weeks following hospitalization.We recommend that the Short Physical Performance Battery (SPPB) be used in the future as one of the primary screening tools for post‐COVID‐19 patients following hospitalization.

Background: To examine the correlation between physical performance and muscle strength and the variables obtained from tensiomyography and myotonometry. Methods: Fifty-two older adults able to complete functional tests participated in this observational study. Variables of maximal radial muscle displacement (Dm) and contraction time (Tc) (using tensiomyography) and muscle stiffness (using myotonometry) of the rectus femoris and vastus lateralis muscles were assessed. Physical performance (Short Physical Performance Battery, Timed Up and Go, Five Times Sit to Stand, and walking speed), isometric knee extension strength, and grip strength were assessed. A correlation analysis was performed between all the variables. Results: A significant correlation between the Short Physical Performance Battery and the rectus femoris (rho = 0.491) and vastus lateralis Dm (rho = 0.329) was found. Significant correlations between the Five Times Sit to Stand Test and the Dm values of the rectus femoris (rho = −0.340) and Dm (rho = −0.304), and stiffness (rho = −0.345) in the vastus lateralis, were also found. No significant correlations were found between tensiomyography and myotonometry, the Timed Up and Go, and walking speed, nor between tensiomyography and myotonometry and grip strength or isometric knee extension strength. Conclusions: Functional tests should be prioritized in the assessment of older adults, but further research into muscle quality using technology is advisable. [ABSTRACT FROM AUTHOR]

This study compared resistance training, aerobic training and muscular endurance training, on functional autonomy and quality of life of the elderly. The present study encompassed 133 participants, divided into four groups, who performed 16 weeks of resistance training, aerobic training and muscular endurance training, in addition to the control group that did not perform any practice. The GDLAM protocol was used to assess functional autonomy, and the WHOQOL-OLD questionnaire was used to assess the quality of life. After analysing the results, it was found that despite the positive effects for all experimental groups, the resistance training group was more efficient in reducing the time to perform functional autonomy tests (Δ%-22.5876, p<0.0001). Regarding the quality of life, the same group presented a significant difference for domain 6, which deals with intimacy, raising the overall quality of life of individuals (Δ% 11.96531, p<0.0001). It was concluded that resistance training showed a higher rate of improvement in functional autonomy and quality of life of the elderly. However, it would be imprudent to rule out the positive effects provided by the other training analysed. In this sense, the findings of this study reinforce the regular and oriented practice of physical exercises of different types for the elderly, being an important and decisive tool in the maintenance and improvement of multiple health variables.

Background. Running induces adaptive responses, such as muscle fatigue that alter muscle strength and power. Button cupping therapy has been applied in clinical practice, under the theories that its application influences the microcirculation and the nervous system, however, there is a scarcity of studies that investigate its effects in athletes. In this context, this protocol aims to evaluate the effects of sliding cupping therapy on pain, perception of fatigue and muscle performance after a 10 km run, with the hypothesis that cupping will produce expected changes when it occurs to the other group. Methods. This is a sham-controlled, randomized, double-blind clinical trial, in which 64 volunteers will be randomly allocated into two groups of 32 participants: intervention group (sliding suction cup with gentle suction on the quadriceps) and sham group (sliding suction cup without compression on the quadriceps). The participants will be evaluated before the race, after the race, immediately, 24 h and 48 h after the intervention, through isokinetic dynamometry, vertical jump test, algometry, and scales of perception of pain and fatigue and perception of recovery. Statistical significance will be set at 5% and a 95% confidence interval (95%CI). Conclusions. This sham-controlled, randomized and blinded clin ical trial protocol may serve as a basis for further research, contributing with a scientific direction for the application of sliding cupping therapy after physical activity.

Background and Purpose: Physical functioning refers to the ability to independently perform activities that require physical ability, and may be an important tool for predicting a higher risk of hospitalization. The objective of this study was to verify whether aspects of physical functioning are independently associated with the risk for new hospitalization in older adults seen in primary health care. Methods: This prospective cohort study consisted of 473 older adults 60 years and older who had not been hospitalized in the prior year. Hospitalization records were obtained with authorization from the hospital admission. Depending on physical functioning, the probability of a new hospital admission within the next 5 years was determined based on survival analysis and the Kaplan-Meier curve. Physical functioning was evaluated using 5 easy-to-administer tests: handgrip strength using a Jamar dynamometer, functional performance using the Short Physical Performance Battery, balance using the step test, mobility using the Timed Up and Go (TUG) test, and gait speed using the 4-m walk test. The association between poor physical functioning and new hospitalization was verified using a Cox regression model, adjusted for sex, age, number of comorbidities, number of medications, and BMI. Models were implemented separately for each physical functioning test. Results: In the sample, 32% had been hospitalized at least once in 5 years. The Kaplan-Meier curve showed a decrease in the probability of nonhospitalization within the next 5 years. Cox regression analysis showed an association between hospitalization within the next 5 years and mobility on the TUG test of more than 12.4 seconds in the crude (hazard ratio [HR] = 1.33, 95% CI = 1.10-1.60) and adjusted models (HR = 1.26, 95% CI = 1.02-1.56), and balance using the step test of more than 7.5 seconds in the crude (HR = 1.27, 95% CI = 1.03-1.56) model. Conclusions: Physical functioning tests demonstrated that poor physical performance predicts new hospitalization, and reinforced the importance of their application in physical therapy practice in primary health care settings.

What is the effect of high-velocity power training (HVPT) compared with traditional resistance training (TRT) on functional performance in older adults? What is the quality of intervention reporting for the relevant literature? Systematic review and meta-analysis of randomised controlled trials. Older adults (aged > 60 years), regardless of health status, baseline functional capacity or residential status. High-velocity power training with the intent to perform the concentric phase as quickly as possible compared with traditional moderate-velocity resistance training performed with a concentric phase of ≥ 2 seconds. Short Physical Performance Battery (SPPB), Timed Up and Go test (TUG), five times sit-to-stand test (5-STS), 30-second sit-to-stand test (30-STS), gait speed tests, static or dynamic balance tests, stair climb tests and walking tests for distance. The quality of intervention reporting was assessed with the Consensus on Exercise Reporting Template (CERT) score. Nineteen trials with 1,055 participants were included in the meta-analysis. Compared with TRT, HVPT had a weak-to-moderate effect on change from baseline scores for the SPPB (SMD 0.27, 95% CI 0.02 to 0.53; low-quality evidence) and TUG (SMD 0.35, 95% CI 0.06 to 0.63; low-quality evidence). The effect of HVPT relative to TRT for other outcomes remained very uncertain. The average CERT score across all trials was 53%, with two trials rated high quality and four rated moderate quality. HVPT had similar effects to TRT for functional performance in older adults, but there is considerable uncertainty in most estimates. HVPT had better effects on the SPPB and TUG, but it is unclear whether the benefit is large enough to be clinically worthwhile. [ABSTRACT FROM AUTHOR]

Manual therapy has recently gained much interest in managing COVID-19 patients. This study aimed to mainly compare the effect of diaphragm manual release to the effect of conventional breathing exercises and prone positioning on physical functional performance in women with COVID-19. Forty COVID-19 women patients completed this study. They were randomly assigned to two groups. Group A received diaphragm manual release, and group B received conventional breathing exercises and prone positioning. Both groups received pharmacological treatment. Inclusion criteria were moderate COVID-19 illness, women patients, and ages from 35 to 45 years. The outcome measures were 6-min walk distance (6MWD), chest expansion, Barthel index (BI), oxygen saturation, fatigue Assessment Scale (FAS), and Medical Research Council (MRC) dyspnea scale. Both groups showed significant improvements in all outcome measures compared to the baseline (p < 0.001). Compared to group B, group A showed more significant improvements in the 6MWD (MD, 22.75 m; 95% CI, 15.21 to 30.29; p < 0.001), chest expansion (MD, 0.80 cm; 95% CI, 0.46 to 1.14; p < 0.001), BI (MD, 9.50; 95% CI, 5.69 to 13.31; p < 0.001), the O 2 saturation (MD, 1.3%; 95% CI, 0.71 to 1.89; p < 0.001), the FAS (MD, −4.70; 95% CI, −6.69 to −2.71; p < 0.001), and dyspnea severity assessed by the MRC dyspnea scale (p = 0.013) post-intervention. Combined with pharmacological treatment, diaphragm manual release could be superior to conventional breathing exercises and prone positioning in improving physical functional performance, chest expansion, daily living activities, O 2 saturation, and measures of fatigue and dyspnea in middle-aged women with moderate COVID-19 illness.

This systematic review pooled evidence from randomised controlled trials (RCTs) on the effectiveness of dietary upregulators of nitric oxide (NO) in improving the walking and quality of life of patients with peripheral artery disease (PAD). RCTs examining the effect of dietary upregulators of NO in patients with PAD were included. The primary outcome was the maximum walking distance. Secondary outcomes were the initial claudication distance, the six-minute walking distance, quality of life, the ankle-brachial pressure index (ABI), adverse events and risk of mortality, revascularisation or amputation. Meta-analyses were performed using random effects models. The risk of bias was assessed using Cochrane's ROB-2 tool. Leave-one-out and subgroup analyses were conducted to assess the effect of individual studies, the risk of bias and intervention type on pooled estimates. Thirty-four RCTs involving 3472 participants were included. Seven trials tested NO donors, nineteen tested antioxidants, three tested NO synthase inducers and five tested enhancers of NO availability. Overall, the dietary supplements significantly improved the initial claudication (SMD 0.34; 95%CI 0.04, 0.64; p = 0.03) but not maximum walking (SMD 0.13; 95%CI −0.17, 0.43; p = 0.39) distances. Antioxidant supplements significantly increased both the maximum walking (SMD 0.36; 95%CI 0.14, 0.59; p = 0.001) and initial claudication (SMD 0.58; 95%CI 0.26, 0.90; p < 0.001) distances. The dietary interventions did not improve the physical function domain of the Short Form-36 (SMD −0.16; 95%CI −0.32, 0.00; p = 0.38), ABI or risk of adverse events, mortality, revascularisation or amputation. Dietary NO upregulators, especially antioxidants, appear to improve the initial claudication distance in patients with PAD. Larger high-quality RCTs are needed to fully examine the benefits and risks of these treatments. PROSPERO Registration: CRD42022256653. [ABSTRACT FROM AUTHOR]

Functional impairment predicts mortality and health care utilization. However, validated measures of functional impairment are not routinely collected during clinical encounters and are impractical to use for large-scale risk-adjustment or targeting interventions. This study's purpose was to develop and validate claims-based algorithms to predict functional impairment using Medicare Fee-for-Service (FFS) 2014–2017 claims data linked with post-acute care (PAC) assessment data and weighted to better represent the overall Medicare FFS population. Using supervised machine learning, predictors were identified that best predicted two functional impairment outcomes measured in PAC data—any memory limitation and a count of 0–6 activity/mobility limitations. The memory limitation algorithm had moderately high sensitivity and specificity. The activity/mobility limitations algorithm performed well in identifying beneficiaries with five or more limitations, but overall accuracy was poor. This dataset shows promise for use in PAC populations, though generalizability to broader older adult populations remains a challenge. [ABSTRACT FROM AUTHOR]

This study aimed to evaluate the efficacy of an individualized remote exercise program on the improvement of body composition and physical fitness of a heterogeneous group of patients who completed breast cancer treatment. This prospective study included 107 women aged 18 to 60, shortly after curative treatment for localized breast cancer, at the Erasto Gaertner Cancer Hospital (HEG) in Curitiba, PR, Brazil. Body composition, maximal oxygen consumption, and muscle resistance were evaluated after nine months of intervention while considering adherence to the program, level of physical activity, presence of binge eating disorder, tumor classification, and treatment type. Seventy-eight women (72.8%) adhered to the training program. Adherent participants showed significant changes in body mass ([-4.3 ± 3.6] kg; p < 0.000 1), body mass index ([-1.6 ± 1.5] kg⋅m-2; p < 0.000 1), body fat (-3.4% ± 3.1%; p < 0.000 1), maximal oxygen consumption ([7.5 ± 2.0] ml⋅kg-1⋅min-1); p < 0.000 1), and abdominal resistance ([11.2 ± 2.8] reps; p < 0.000 1). In contrast, these variables did not change significantly in the non-adherent group. Among the adherent participants, those subclassified in the severe binge group showed a more noticeable reduction in body mass, body mass index, and body fat (p < 0.05) than those in the non-binge group. Individualized remotely-guided physical exercise programs can improve the body composition and physical fitness of women undergoing post-breast cancer surveillance, regardless of pathological history or treatment.

Amyotrophic lateral sclerosis (ALS) is a debilitating neurodegenerative disorder with complex biology and significant clinical heterogeneity. Many preclinical and early phase ALS clinical trials have yielded promising results that could not be replicated in larger phase 3 confirmatory trials. One reason for the lack of reproducibility may be ALS biological and clinical heterogeneity. Therefore, in this review, we explore sources of ALS heterogeneity that may reduce statistical power to evaluate efficacy in ALS trials. We also review efforts to manage clinical heterogeneity, including use of validated disease outcome measures, predictive biomarkers of disease progression, and individual clinical risk stratification. We propose that personalized prognostic models with use of predictive biomarkers may identify patients with ALS for whom a specific therapeutic strategy may be expected to be more successful. Finally, the rapid application of emerging clinical and biomarker strategies may reduce heterogeneity, increase trial efficiency, and, in turn, accelerate ALS drug development.

ObjectivesTo examine the association of lifetime history of traumatic brain injury (TBI) with later-life physical impairment (PI) and functional impairment (FI) and to evaluate the impact of neurobehavioral symptoms that frequently co-occur with TBI on these relations.ParticipantsA total of 1148 respondents to the 2014 Wave of the Health and Retirement Study, a nationally representative survey of older community-dwelling adults, randomly selected to participate in a TBI exposure survey. They reported no prior TBI (n = 737) or prior TBI (n = 411).DesignCross-sectional survey study.Main measuresPhysical impairment (self-reported difficulty with ≥1 of 8 physical activities); FI (self-reported difficulty with ≥1 of 11 activities of daily living); self-reported current neurobehavioral symptoms (pain, sleep problems, depression, subjective memory impairment); The Ohio State University TBI Identification Method (OSU-TBI-ID)-short form.AnalysesStepwise logistic regression models ([1] unadjusted; [2] adjusted for demographics and medical comorbidities; [3] additionally adjusted for neurobehavioral symptoms) compared PI and FI between TBI groups.ResultsTraumatic brain injury-exposed (mean: 33.6 years postinjury) respondents were younger, less likely to be female, and reported more comorbidities and neurobehavioral symptoms. Although TBI was significantly associated with increased odds of PI and FI in unadjusted models and models adjusted for demographics/comorbidities (adjusted odds ratio, 95% confidence interval: PI 1.62, 1.21-2.17; FI 1.60, 1.20-2.14), this association was no longer statistically significant after further adjustment for neurobehavioral symptoms.ConclusionHistory of TBI is associated with substantial PI and FI among community-dwelling older adults. Further research is warranted to determine whether aggressive management of neurobehavioral symptoms in this population may mitigate long-term PI and FI in this population.
