RESUMO
Background: Open, grossly contaminated femoral shaft fractures pose a significant threat for fracture-related infection. Traditional treatment for these injuries consists of irrigation and debridement with temporizing external fixation placement and staged conversion to definitive fixation. Methods: We describe a protocol for acute antibiotic cement nailing of open femoral shaft fractures as an infection prophylaxis modality in fractures with a high risk of infection and present three cases. Results: Three patients presented with open femoral shaft fractures with large soft tissue defects and gross contamination and were successfully treated with acute retrograde antibiotic nailing and external fixation with later conversion to definitive metallic nailing. They did not develop infection and had acceptable postoperative function and fracture alignment. Conclusion: This technique of early infection prophylaxis after open femoral shaft fracture is reproducible, pragmatic, and cost-effective.
RESUMO
Background: Successful total hip arthroplasty (THA) relies on the correct implant position. THA accuracy can be improved with the use of intraoperative fluoroscopic-assisted computer navigation. Artificial intelligence (AI) software may enhance fluoroscopic navigation; however, the accuracy of the AI compared to human-controlled software in assessing acetabular component position and leg length discrepancy (LLD) has not been studied. Methods: We analyzed 420 consecutive primary THAs performed by a single surgeon using fluoroscopic-assisted computer navigation software. The first cohort of 211 patients required inputs from a human technician (manual), while the second cohort of 209 patients used an automated version of the software controlled by AI. The intraoperative acetabular component placement (inclination and anteversion) and LLD were recorded and compared to the 2-week postoperative standing anterior-posterior pelvis radiograph. Results: Ninety-four percent (199/211) of cups in the manual cohort and 95% (198/209) of cups in the AI cohort were within the Lewinnek "safe-zone" (P = 1.0). In the manual cohort, 69% (146/211) of THAs had a final LLD within ±2 mm of the intraoperatively navigated LLD (ie, ΔLLD ≤2 mm). In the AI cohort, 66% (137/209) of THAs had a final LLD within ±2 mm of the intraoperatively navigated LLD (P = .47). Ninety-nine percent (209/211) of hips in the manual cohort and 98% (205/209) of hips in the AI cohort had a final LLD within ±5 mm of the intraoperatively navigated LLD (P = .45). Conclusions: Both AI and human-controlled versions of the same navigation platform were similarly accurate for navigating cup position within the Lewinnek "safe zone" and LLD accuracy.
RESUMO
Surgical management of the subscapularis tendon is critical to a successful outcome following anatomic total shoulder arthroplasty. However, the optimal surgical technique for adequate exposure of the glenohumeral joint while mini-mizing complications resulting from subscapularis tendon dysfunction continues to be controversial. Common surgical techniques for the management of the subscapularis tendon include tenotomy, peeling, sparing, and lesser tuberosity oste-otomy. Despite a number of published studies comparing these techniques, no consensus has been reached regarding optimal management. This article reviews the extensive literature on the biomechanical, radiologic, and clinical outcomes of each technique, including recently published comparison studies.

Down syndrome (DS) is characterised by a duplication of chromosome-21 and is linked to co-occurring physical and mental health conditions, including low self-efficacy and disturbed mood states. The purpose of this study was to investigate the effects of an eight-week prescribed physical and/or cognitive training intervention on measures of mood disturbance, life satisfaction and self-efficacy in a population of adults with DS. Eighty-three participants (age 27.1 ± 8.0 years) from across five continents volunteered. Participants were assigned using matched groups based upon performance in a modified six-minute walk test to either an exercise (EXE) 3 × 30 min of walking/jogging per week, cognitive training (COG) 6 × 20 min per week, a combined group (COM) or the control (CON) who did not complete any intervention. Profile of Mood States (POMS) were assessed using a five-point scale across 65 categories pre- and post-study as well as upon completion of each week of the intervention. In addition, Satisfaction with Life Scale (SWLS) and self-efficacy using the Generalised Self-Efficacy scale (GSE) were recorded before and after the intervention. GSE increased for all participants by 1.9 ± 5.2 (p = 0.002) from pre- to post-intervention, while POMS showed significant changes for the whole group from pre- to post-intervention for tension (p < 0.001), depression (p < 0.001) and for anger (p < 0.001). In addition, significant correlations were observed between SWLS and ΔTMD, Δtension, Δanger, and Δfatigue (p < 0.05) for EXE. Both COG and EXE provide a framework for empowering enhancements in life satisfaction, self-efficacy and mood states fostering improvements in quality of life.

The duplication of chromosome 21, as evidenced in Down Syndrome (DS), has been linked to contraindications to health, such as chronotropic and respiratory incompetence, neuromuscular conditions, and impaired cognitive functioning. The purpose of this study was to examine the effects of eight weeks of prescribed exercise and/or cognitive training on the physical and cognitive health of adults with DS. Eighty-three participants (age 27.1 ± 8.0 years) across five continents participated. Physical fitness was assessed using a modified version of the six-minute walk test (6MWT), while cognitive and executive functions were assessed using the Corsi block test, the Sustained-Attention-To-Response Task (SART), and the Stroop task (STROOP). All were completed pre- and post-intervention. Participants were assigned to eight weeks of either exercise (EXE), 3 × 30 min of walking/jogging per week, cognitive training (COG) 6 × ~20 min per week, a combined group (COM), and a control group (CON) engaging in no intervention. 6MWT distance increased by 11.4% for EXE and 9.9% for COM (p < 0.05). For SART, there were positive significant interactions between the number of correct and incorrect responses from pre- to post-intervention when participants were asked to refrain from a response (NO-GO-trials) across all experimental groups (p < 0.05). There were positive significant interactions in the number of correct, incorrect, and timeout incompatible responses for STROOP in EXE, COG, and COM (p < 0.05). Walking generated a cognitive load attributed to heightened levels of vigilance and decision-making, suggesting that exercise should be adopted within the DS community to promote physical and cognitive well-being.

Cardiorespiratory fitness is a key component of health-related fitness. It is a necessary focus of improvement, especially for those that have poor fitness and are classed as untrained. However, much research has shown individuals respond differentially to identical training programs, suggesting the involvement of a genetic component in individual exercise responses. Previous research has focused predominantly on a relatively low number of candidate genes and their overall influence on exercise responsiveness. However, examination of gene-specific alleles may provide a greater level of understanding. Accordingly, this study aimed to investigate the associations between cardiorespiratory fitness and an individual's genotype following a field-based endurance program within a previously untrained population. Participants (age: 29 ± 7 years, height: 175 ± 9 cm, mass: 79 ± 21 kg, body mass index: 26 ± 7 kg/m2) were randomly assigned to either a training (n = 21) or control group (n = 24). The training group completed a periodized running program for 8-weeks (duration: 20-30-minutes per session, intensity: 6-7 Borg Category-Ratio-10 scale rating, frequency: 3 sessions per week). Both groups completed a Cooper 12-minute run test to estimate cardiorespiratory fitness at baseline, mid-study, and post-study. One thousand single nucleotide polymorphisms (SNPs) were assessed via saliva sample collections. Cooper run distance showed a significant improvement (0.23 ± 0.17 km [11.51 ± 9.09%], p < 0.001, ES = 0.48 [95%CI: 0.16-0.32]), following the 8-week program, whilst controls displayed no significant changes (0.03 ± 0.15 km [1.55 ± 6.98%], p = 0.346, ES = 0.08, [95%CI: -0.35-0.95]). A significant portion of the inter-individual variation in Cooper scores could be explained by the number of positive alleles a participant possessed (r = 0.92, R2 = 0.85, p < 0.001). These findings demonstrate the relative influence of key allele variants on an individual's responsiveness to endurance training.

RESUMO
Purpose: To assess the preoperative and postoperative performance of the Patient-Reported Outcomes Measurement Information System Upper Extremity (PROMIS-UE, version 2.0) outcome score in comparison to the American Shoulder and Elbow Surgeons (ASES) and Western Ontario Rotator Cuff Index (WORC) instruments in patients undergoing rotator cuff repair. Methods: This prospective longitudinal study included 91 patients undergoing rotator cuff repair. Patients completed the PROMIS-UE, ASES, and WORC instruments preoperatively and postoperatively at 2 weeks, 6 weeks, 3 months, and 12 months. The Pearson correlation coefficient (r) between these tools was calculated at each time point. Correlations were graded as excellent (>0.7), excellent-good (0.61-0.7), good (0.4-0.6), or poor (<0.4). Responsiveness to change was assessed using the effect size and the standardized response mean. Floor and ceiling effects for each instrument were also assessed. Results: The PROMIS-UE instrument showed good to excellent correlation with the legacy instruments at all time points. There were variations in the measured effect sizes of the various instruments, with the PROMIS-UE instrument showing responsiveness to change at 3 and 12 months but the ASES and WORC instruments showing responsiveness at 6 weeks, 3 months, and 12 months. Both PROMIS-UE and ASES scores displayed ceiling effects at 12 months. Conclusions: The PROMIS-UE instrument shows excellent correlation with the ASES instrument and a rotator cuff-specific outcome instrument-the WORC instrument-preoperatively and at 1 year after arthroscopic rotator cuff repair. Variations in the measured effect sizes at different postoperative time points and high ceiling effects of the PROMIS-UE instrument at the 1-year time point may limit its utility in the early postoperative phase and at long-term follow-up after rotator cuff repair. Clinical Relevance: The performance of the PROMIS-UE outcome measure after arthroscopic rotator cuff repair was investigated.
RESUMO
PURPOSE: To calculate and determine what factors are associated with achieving the Minimal Clinically Important Difference (MCID) and the Substantial Clinical Benefit (SCB) of Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity Computer Adaptive Testing v2.0 (UE), Pain Interference (P-Interference), and Pain Intensity (P-Intensity) in patients undergoing arthroscopic rotator cuff repair (aRCR). METHODS: The change in PROMIS scores representing the optimal cutoff for a ROC curve with an area under the curve analysis was used to calculate the anchor-based MCID and SCB. To assess the responsiveness of each PROM, effect sizes and standardized response means (SRM) were calculated. To identify factors associated with attaining the MCID and SCB, univariate and multivariate logistic regression analyses were performed. RESULTS: A total of 323 patients with an average age of 59.9 ± 9.5 were enrolled in this study, of which, 187/323 [57.9%] were male and 136/323 [42.1%] were female. The anchor-based MCID for PROMIS UE, P-Interference, and P-Intensity was: 9.0, 7.5, and 11.2, respectively. The respective SCB was 10.9, 9.3, and 12.7. Effect size and SRM were: PROMIS UE (1.4, 1.3), P-Interference (1.8, 1.5), and P-Intensity (2.3, 2.0). Lower preoperative P-Intensity scores (p = 0.02), dominant arm involvement (p = 0.03), and concomitant biceps tenodesis (p = 0.03) were associated with patients achieving the SCB for PROMIS UE. CONCLUSION: A large responsiveness for each of the PROMIS instruments due to the majority of patients reporting great improvement after aRCR and a small standard deviation across all outcome measures was shown in our study. Lower preoperative P-Intensity scores and concomitant biceps tenodesis were associated with higher odds of achieving the SCB for PROMIS UE. The knowledge of MCID and SCB values for PROMIS instruments will allow the surgeon to determine whether the improvements in the PROMIS scores after aRCR are clinically meaningful. LEVEL OF EVIDENCE: Level III.

INTRODUCTION: The purpose of this study is to calculate the minimal clinically important difference (MCID), substantial clinical benefit (SCB), and patient acceptable symptom state (PASS) of Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity Computer Adaptive Testing v2.0 (UE), Pain Interference (P-Interference), and Pain Intensity (P-Intensity) in patients treated nonoperatively for idiopathic adhesive capsulitis (IAC). METHODS: The anchor-based MCID, SCB, and PASS were calculated as the change in PROMIS scores representing the optimal cutoff for a ROC curve with an area under the curve (AUC) analysis. The distribution-based MCID was calculated as a range between the average standard error of measurement multiplied by two different constants: 1 and 2.77. Effect sizes and standardized response means (SRM) were calculated to assess the responsiveness of each PROMIS instrument while regression analyses were performed to identify factors associated with achieving these thresholds. RESULTS: This study enrolled 115 patients. The anchor-based MCID for PROMIS UE, P-Interference, and P-Intensity was 5.11, 4.16, and 8.16, respectively. The respective SCB was 8.44, 6.65, and 10.05. The respective PASS was 8.47, 7.01, and 10.41. The odds of achieving MCID values in adhesive capsulitis were negatively affected by gender (male), higher forward elevation at the time of presentation, higher pain scores (P-Interference), need for ≥ 2 corticosteroid injections, and a concomitant diagnosis of diabetes. CONCLUSION: The MCID, SCB, and PASS parameters for PROMIS scores can be utilized to determine the clinical meaningfulness of patient-reported improvements in these instruments during the nonoperative treatment and as a research tool to compare the efficacy of new treatments for adhesive capsulitis. LEVEL OF EVIDENCE: Level III, basic science study, validation of outcome instruments. Key points ⢠This is the first study to calculate the minimal clinically important difference (MCID), substantial clinical benefit (SCB), and patient acceptable symptomatic state (PASS) for the Patient-Reported Outcome Measurement Information System (PROMIS) Upper Extremity and Pain instruments in patients with idiopathic adhesive capsulitis (IAC) of the shoulder.⢠This study determined the impact of symptom severity, demographics, and comorbidities on achieving the MCID, SCB, and PASS for PROMIS instruments in IAC patients treated nonoperatively.

Purpose: The United Kingdom (UK) government imposed its first national lockdown in response to COVID-19 on the 23rd of March 2020. Physical activity and sedentary behaviour levels are likely to have changed during this period. Methods: An online survey was completed by n = 266 adults living within the UK. Differences in day-to-day and recreational physical activity (at moderate and vigorous intensities), travel via foot/cycle, and sedentary behaviour were compared before and during the initial COVID-19 lockdown. Results: The median level of total weekly physical activity significantly reduced (- 15%, p < 0.001) and daily sedentary time significantly increased (+ 33%, p < 0.001). The former was caused by a significant reduction in weekly day-to-day physical activity at moderate intensities (p < 0.001), recreational activities at vigorous (p = 0.016) and moderate (p = 0.030) intensities, and travel by foot/cycle (p = 0.031). Sub-group analyses revealed that some populations became disproportionally more physically inactive and/or sedentary than others, such as those that were: living in a city (versus village), single (versus a relationship), an athlete (versus non-athlete), or earning an average household income < £25,000 (versus > £25,000). Conclusions: Now that the UK is transitioning to a state of normal living, strategies that can help individuals gradually return to physical activities, in accordance with the 2020 WHO guidelines, are of paramount importance to reducing risks to health associated with physical inactivity and sedentary behaviour.
RESUMO
Ischaemic preconditioning (IPC) involves the use of repeated occlusions and reperfusions of the peripheral muscle blood supply at a limb. This systematic literature review examines the typical responses in response to the method of application during an IPC applied at the lower limb. This review focuses on the physiological responses for VO2max, haemoglobin, metabolic and genetic responses to various IPC interventions. The literature search was performed using four databases and assessed using the PRISMA search strategy and COSMIN to assess the quality of the articles. Seventeen articles were included in the review, with a total of 237 participants. While there is variation in the method of application, the average occlusion pressure was 222 ± 34 mmHg, ranging from 170 to 300 mmHg typically for 3 or 4 occlusion cycles. The distribution of this pressure is influenced by cuff width, although 8 studies failed to report cuff width. The majority of studies applies IPC at the proximal thigh with 16/17 studies applying an occlusion below this location. The results highlighted the disparities and conflicting findings in response to various IPC methods. While there is some agreement in certain aspects of the IPC manoeuvre such as the location of the occlusion during lower limb IPC, there is a lack of consensus in the optimal protocol to elicit the desired responses. This offers the opportunity for future research to refine the protocols, associated responses, and mechanisms responsible for these changes during the application of IPC.
RESUMO
Background: The purpose of this study is to report the outcomes in patients undergoing arthroscopic tuberoplasty for symptomatic irreparable rotator cuff tear (RCT). Methods: This is a retrospective cohort study comparing preoperative and postoperative data of patients undergoing arthroscopic tuberoplasty for symptomatic irreparable RCT. Exclusion criteria included open tuberoplasty, concomitant partial RCT repair, glenohumeral arthritis, concomitant ipsilateral extremity fractures, <12 months follow-up, or pseudoparalysis. Demographics, shoulder range of motion (ROM), RCT morphology, re-operation rates, satisfaction and outcome scores were collected from medical records and questionnaires. Outcome scores included Patient Reported Outcome Measurement Information System Upper Extremity (PROMIS), American Shoulder and Elbow Surgeons score (ASES), Subjective Shoulder Value (SSV), and pain Visual Analog Score (VAS). Results: Out of 28 patients identified between 2012 and 2019, 20 (21 shoulders) were available for follow-up at a mean of 43.3 ± 20.9 months. Mean age was 64.6 ± 8.8 years. Mean PROMIS was 37.7 ± 7.3, ASES was 82.9 ± 13.8, and SVV was 67.1 ± 19.4. VAS with activity decreased from 5.0 ± 2.9 preoperatively to 2.3 ± 2.6 (P = .0029). Pre- and post-operative ROM were unchanged. There were 4 failures requiring revision. The remaining 17 patients reported high satisfaction scores (3.4 ± 0.7) and 15 (88.2%) answered "yes" to getting the procedure again, with 3/4 failures stating they would also undergo arthroscopic tuberoplasty again. Conclusion: Arthroscopic tuberoplasty demonstrates high levels of satisfaction and pain reduction in symptomatic irreparable RCT. In appropriately indicated patients, this treatment should be considered prior to other salvage options.
RESUMO
(1) Background: Near-infrared spectroscopy (NIRS) is an innovative and non-invasive technology used to investigate muscular oxygenation. The aim of this study is to assess the within- and between-session reliability of the NIRS Portamon (Artinis, Elst, Netherlands) device following three sets of induced muscle ischemia. (2) Methods: Depending on the experimental group (G1, G2 or G3), a cuff was inflated three times on the left upper arm to 50 mmHg (G1), systolic blood pressure (SBP) + 50 mmHg (G2) or 250 mmHg (G3). Maximum, minimum and reoxygenation rate values were assessed after each occlusion phase, using a Portamon device placed on the left brachioradialis. Reliability was assessed with intraclass correlation coefficient (ICC) value and ICC 95% confidence interval (CI-95%), coefficient of variation (CV) and standard error of measurement (SEM) (3) Results: Our results showed a good to excellent reliability for maximums and minimums within-session. However, the reoxygenation rate within sessions as well as measurements between sessions cannot predominantly show good reliability. (4) Conclusions: Multiple measurements of maximums and minimums within a single session appeared to be reliable which shows that only one measurement is necessary to assess these parameters. However, it is necessary to be cautious with a comparison of maximum, minimum and reoxygenation rate values between sessions.

BACKGROUND: History of prior rotator cuff repair (RCR) may adversely affect the outcomes of reverse total shoulder arthroplasty (RTSA), but there is no information regarding the influence of prior superior capsular reconstruction (SCR) surgery on the outcomes of RTSA. The purpose of this study is to evaluate the outcomes of RTSA following failed arthroscopic SCR. METHODS: All patients who underwent RTSA for failed SCR (SCR cohort) at our institution were identified from our institutional database. A comparative cohort of patients who had RTSA with a history of failed RCR (Control cohort) was also reviewed. Demographic information, 90-day complication rate, 90-day emergency department visits, length of stay, and outcome scores (patient-reported outcomes measurement information system [PROMIS] physical function upper extremity, Visual Analog Scale score, and range of motion) were compared. RESULTS: From 2015 to 2020, 87 arthroscopic SCRs were performed at our institution and of these, 13 patients underwent RTSA at a mean time of 14.6 months (5.8-32.4) after SCR and were followed up for an average of 17.9 months (1.6-44.6). The average number of shoulder surgeries prior to RTSA was 2.8 (1-7), with the last surgery being SCR. During the same period, we identified 15 patients who underwent an RTSA after a failed RCR (control cohort). The RTSA in the control cohort was performed on average at 12.8 months (1.5-39.5) following the last RCR, and patients were followed up for an average of 27.7 months (2.8-53.9). The average number of shoulder surgeries before the RTSA in the control cohort was 1.4 (1-3). Although the SCR cohort had significant improvements in pain scores and forward flexion (FF), there was only a modest functional improvement with PROMIS scores and no meaningful improvement with external rotation. Complications (23%) in the SCR cohort included 1 periprosthetic joint infection requiring 2-stage revision, 1 acromion stress fracture, and 1 ulnar neuritis. Overall, compared to the SCR cohort, patients in the control cohort had better function (PROMIS physical function upper extremity), lower Visual Analog Scale score, and greater range of motion (FF and external rotation) preoperatively and at last follow-up, but there were no differences in the length of stay and 90-day emergency department visits, infection, and complication rate between the 2 cohorts. CONCLUSION: RTSA after failed SCR improves pain and FF but is associated with modest functional improvements and high complication rates. However, these findings will require confirmation in a larger cohort with longer follow-up.
RESUMO
The Patient-Reported Outcomes Measurement Information System Upper Extremity Computer Adaptive Test (PROMIS UE CAT) is a newer patient-reported outcome measure for upper extremity physical function. To date, no longitudinal study exists assessing PROMIS UE CAT responsiveness in patients undergoing shoulder arthroplasty. The purpose of this prospective longitudinal study is to report PROMIS UE CAT responsiveness to change and correlation to legacy instruments in patients undergoing total shoulder arthroplasty (TSA). Ninety-six patients (97 shoulders) undergoing TSA completed the PROMIS UE, Oxford Shoulder Score (OSS), American Shoulder and Elbow Surgeons (ASES), and Simple Shoulder Test (SST) preoperatively and postoperatively at 6 weeks, 12 weeks, and after 6 months. Spearman's correlation coefficients (r) were calculated between PROMIS UE and other scores at each time-point. Responsiveness to change was assessed using the effect size (Cohen's d) and standardized response mean compared with the preoperative time-point. Floor and ceiling effects were also assessed. PROMIS UE CAT demonstrated positive responsiveness at all time-points after TSA. It demonstrated excellent correlation (range: 0.68-0.84) with ASES, SST, and OSS at all postoperative time-points, but the correlation was weaker (r < 0.6, except OSS) preoperatively. Only OSS and SST showed ceiling effects at the 6-12-month time-point (16.8% and 18.2%, respectively). PROMIS UE CAT responsiveness to change and strength of correlation with legacy instruments improves with time elapsed after TSA. Further quantification of meaningful responsiveness to change will require estimation of the minimal clinically important difference and substantial clinical benefit for PROMIS UE CAT.

PURPOSE: Coracoid fracture is a rare injury. The aim of this study is to present the demographics, clinical and radiologic characteristics, and outcomes of coracoid fracture in a cohort of 32 patients. METHODS: We queried our institutional electronic medical record database (years 2012-2020) to identify patients with coracoid fractures using specific International Classification of Disease-10 codes. Demographic data, injury details including mechanism of injury and associated injuries, imaging performed, and treatment outcomes were obtained from retrospective chart review. A radiologist reviewed all available imaging studies (radiographs/CT/MRI) and classified the fractures according to Ogawa and Eyres classifications. Missed diagnoses were determined by comparing initial imaging reports with the follow-up imaging obtained in the office. RESULTS: Thirty-two patients with coracoid fractures were identified during the study period. Sixteen fractures (50%) occurred in the setting of low-energy trauma. Twelve fractures were missed on initial radiographs, and diagnosis with three-view radiographs (AP, scapular-Y and axillary) was 88% compared to 33% (p < 0.03) with two views (AP, scapular-Y). The majority of fractures were non-displaced (94%), and 56% were Ogawa Type-II fractures. Associated injuries were seen in 81% of patients. Most fractures (94%) were treated without surgery with excellent outcomes. CONCLUSION: Coracoid fractures continue to be a rare injury. In contrast to previous studies, in this case series of 32 patients, half of the fractures were associated with low-energy trauma, which correlated with higher percentage of non-displaced fractures and Ogawa Type-II fractures. Addition of the axillary view in the trauma radiographic series significantly improved the initial fracture detection rate. LEVEL IV: Retrospective study.

Introduction: The introduction of the COVID-19 lockdown and social distancing policy has the potential to restrict access to physical activity, change exercise behavior, and to increase sedentary behavior. This study was conducted with the support of British Blind Sport and evaluates the effect of the lockdown policy on adults with visual impairments in the United Kingdom (UK). Methods: An online survey based on the World Health Organization's Global Physical Activity Questionnaire was completed by 73 participants (median age 35-44 years, 59% female) to gain information on how the implementation of the lockdown policy by the UK government has affected physical activity and sedentary behavior in adults that are visually impaired. Paired sample t-tests and Wilcoxon signed rank tests were used to analyze continuous and Likert scale data, respectively. Results: The majority of participants continued to exercise during lockdown, but the nature of this activity altered with a significant change to exercising in a private indoor space (+190% (always), z = -3.871, p < 0.001), and those exercising alone (+118% (always), z = -2.595, p = 0.009). The volume of activity reduced in all cases, between -11% and -52%, with significant changes in duration of vigorous day-to-day activity, moderate day-to-day activity, travel by foot or cycle, and vigorous recreational activity. Sedentary behavior increased on average by 21% (t(59) = -2.050, p = 0.045), with a greater effect seen in females (+36%, t(35) = -2.525, p = 0.016). Discussion: Reductions in physical activity volume and increases in sedentary behavior are consequences of the UK lockdown for those with visual impairments. The health and well-being implications of these data to this specific population are of particular concern. Implications for Practitioners: Lockdown measures should be designed with consideration of the needs of people with disabilities. Innovative ways to engage these populations in physical activity are strongly encouraged.
RESUMO
The aim of this systematic review and meta-analysis was to identify a list of common, candidate genes associated with the three components of fitness, specifically cardiovascular fitness, muscular strength, and anaerobic power, and how these genes are associated with exercise response phenotype variability, in previously untrained participants. A total of 3,969 potentially relevant papers were identified and processed for inclusion. After eligibility and study selection assessment, 24 studies were selected for meta-analysis, comprising a total of 3,012 participants (male n = 1,512; females n = 1,239; not stated n = 261; age 28 ± 9 years). Meta-Essentials spreadsheet 1.4 (Microsoft Excel) was used in creating the forest plots and meta-analysis. IBM SPSS statistics V24 was implemented for the statistical analyses and the alpha was set at p ≤ 0.05. 13 candidate genes and their associated alleles were identified, which were associated with the phenotypes of interest. Analysis of training group data showed significant differential phenotypic responses. Subgroup analysis showed; 44%, 72% and 10% of the response variance in aerobic, strength and power phenotypes, respectively, were explained by genetic influences. This analysis established that genetic variability explained a significant proportion of the adaptation differences across the three components of fitness in the participants post-training. The results also showed the importance of analysing and reporting specific gene alleles. Information obtained from these findings has the potential to inform and influence future exercise-related genes and training studies.

BACKGROUND: The Patient-Reported Outcomes Measurement Information System minimal clinically important difference (PROMIS MCID), substantial clinical benefit (SCB), and patient acceptable symptom state (PASS) of patient-reported outcome measures provide clinical significance to patient-reported outcome measures scores. The goal of this study is to measure the MCID, SCB, and PASS of PROMIS Upper Extremity v2.0 (PROMIS UE) in patients undergoing total shoulder arthroplasty (TSA). METHODS: All patients who underwent TSA since October 2017 were identified from our institutional database. Patients who had completed the PROMIS UE outcome measure before surgery were asked to complete a PROMIS UE and anchor survey that contained two transition questions to assess patient satisfaction and change in symptoms since treatment. The anchor-based MCID, SCB, and PASS were calculated as the change in PROMIS UE score that represented the optimal cutoff for a receiver operating characteristic curve. The distribution-based MCID was calculated as a range between the average standard error of measurement multiplied by 2 different constants: 1 and 2.77. RESULTS: This study enrolled 165 patients. The anchor-based MCID for PROMIS UE was calculated to be 8.05 with an AUC of 0.814. The anchor-based SCB was calculated to be 10.0 with an AUC of 0.727. The distribution-based MCID was calculated to be between 3.12 and 8.65. The PASS was calculated to be 37.2 with an AUC of 0.90. CONCLUSIONS: The establishment of MCID, SCB, and PASS for PROMIS UE scores after shoulder arthroplasty provides meaningful and objective clinical interpretation of the improvements in outcome scores after TSA.
