Objectives: This study aimed to determine the relationship between frequently used patient-reported outcome (PRO) measures and a multitask performance outcome (PerfO) measure of general physical function (PF) and to examine the association of these measures with depressive mood, pain, and age.Methods: Frequently used PRO measures of general PF (Patient-Reported Outcomes Measurement Information System [PROMIS] PF item bank, PROMIS PF Short Form 20a, Short Form 36 Physical Function Scale) and a PerfO test battery, namely, the Physical Performance Test (PPT), were administered to 78 adult patients from 3 inpatient clinics (cardiology and angiology, rheumatology and clinical immunology, and psychosomatic medicine) at Charité - Universitätsmedizin Berlin. Pearson correlations were used to investigate the associations between PRO measures and the PPT. To explore the predictive value of age, depressive symptoms, and pain intensity, we conducted multiple linear regression analysis for each PF measure.Results: We found strong linear relationships between PRO measures and PPT sum scores. Correlations between PPT sum scores and PROMIS PF T-scores were r > 0.75. For all PRO and PerfO measures, age was a predictor of general PF whereas depressive mood was not found to be a relevant predictor. Moreover, pain intensity was found to be a significant predictor of PRO measures but not for PPT sum scores.Conclusions: Our findings suggest that frequently used PRO measures and a multitask PerfO measure of general PF can be used to measure a common PF construct. Nevertheless, PF scores based on PRO measures should ideally be controlled for self-rated pain intensity. [ABSTRACT FROM AUTHOR]

Objectives: This study aimed to determine whether responses to Patient-Reported Outcomes Measurement Information System Short Form v2.0 - Physical Function 8c (PROMIS PF8c) items differed when the use of a 7-day recall period was compared with no specified recall period.Methods: Using a within-subject design, we surveyed 1810 individuals from the US general population, administering PROMIS PF8c at survey beginning and end. The order of measure presentation was randomly assigned. We calculated recall difference scores (RDSs) as no recall score minus 7-day recall score using both item response theory-based T scores and raw summed scores. We examined the distribution and created Bland-Altman plots for both RDSTscore and RDSRaw. We also calculated correlations between no recall versus 7-day recall T score and raw scores. Finally, we determined whether differences in no recall versus 7-day recall scores were associated with patient-reported PF.Results: RDSTscore and RDSRaw had means (root mean square differences) of 0.00 (5.43) and -0.04 (3.79), respectively. The vast majority (%) of RDSTscore and RDSRaw values fell between the Bland-Altman limits of agreement (-10.65 to 10.66 and -7.46 to 7.38, respectively). Pearson's correlations between no recall and 7-day recall for T scores and raw scores were 0.88 and 0.87, respectively. Effect sizes for mean RDSTscore and RDSRaw compared across level of Eastern Oncology Cooperative Group performance status, patient global impression of PF severity, and single PF items were near 0.Conclusions: We did not find any significant recall period effect on PF8c responses. Therefore, we recommend the use of the PROMIS physical function standard, with no specified recall time period. [ABSTRACT FROM AUTHOR]

• COVID-19 patients not taking antiviral drugs were more likely to retest positive. • Re-positivity had no effect on the recovery of respiratory and physical function. • The recovery of respiratory and physical function was related to COVID-19 severity. • Normal follow-up may suffice for patients who retest positive during rehabilitation. The aim of this study was to evaluate the respiratory and physical function of patients who retested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA during post-coronavirus disease 2019 (COVID-19) rehabilitation. A total of 302 discharged COVID-19 patients were included. Discharged patients were followed up for 14 days to 6 months. The modified Medical Research Council (mMRC) dyspnea scale, Borg rating of perceived exertion, and manual muscle testing (MMT) scores on day 14 and at 6 months after discharge were compared between the redetectable positive (RP) and non-RP (NRP) groups. Prognoses of respiratory and physical function were compared between patients who recovered from moderate and severe COVID-19. Of the study patients, 7.6% were RP. The proportion of patients who used antiviral drugs was significantly lower in the RP group than in the NRP group. There were no differences in mMRC, Borg, or MMT scores within the RP and NRP groups. The mMRC, Borg, and MMT scores were worse for patients with severe disease when compared to those with moderate disease at both follow-up time points. COVID-19 patients who did not take antiviral drugs were more likely to be RP after discharge. The recovery of respiratory and physical function was not related to re-positivity during rehabilitation, but was related to disease severity during hospitalization. [ABSTRACT FROM AUTHOR]

Background: Nitrate supplements can improve vascular and muscle function. Whether higher habitual dietary nitrate is associated with better muscle function remains underexplored.Objective: The aim was to examine whether habitual dietary nitrate intake is associated with better muscle function in a prospective cohort of men and women, and whether the relation was dependent on levels of physical activity.Methods: The sample (n = 3759) was drawn from the Australian Diabetes, Obesity, and Lifestyle Study (AusDiab) (56% female; mean ± SD baseline age: 48.6 ± 11.1 y). Habitual dietary intake was assessed over 12 y by obtaining an average [of at least 2 time points, e.g., baseline (2000/2001) and 2004/2005 and/or 2011/2012] from a food-frequency questionnaire. Nitrate intake was calculated from a validated nitrate database and other published literature. Muscle function was quantified by knee extension strength (KES) and the 8-ft-timed-up-and-go (8ft-TUG) test performed in 2011/2012. Physical activity was assessed by questionnaire. Generalized linear models and logistic regression were used to analyze the data.Results: Median (IQR) total nitrate intake was 65 (52-83) mg/d, with ∼81% derived from vegetables. Individuals in the highest tertile of nitrate intake (median intake: 91 mg/d) had 2.6 kg stronger KES (11%) and 0.24 s faster 8ft-TUG (4%) compared with individuals in the lowest tertile of nitrate intake (median intake: 47 mg/d; both P < 0.05). Similarly, individuals in the highest tertile of nitrate intake had lower odds for weak KES (adjusted OR: 0.69; 95% CI: 0.47, 0.73) and slow 8ft-TUG (adjusted OR: 0.63; 95% CI: 0.50, 0.78) compared with those in the lowest tertile. Physical activity did not influence the relationship between nitrate intake and muscle function (KES; P-interaction = 0.86; 8ft-TUG; P-interaction = 0.99).Conclusions: Higher habitual dietary nitrate intake, predominantly from vegetables, could be an effective way to promote lower-limb muscle strength and physical function in men and women.

Context: Sickle cell disease (SCD) is associated with recurrent pain that could lead to abnormal sensory patterns (ASPs).Objectives: The purpose of this study is to compare children with SCD who had normal sensory patterns (NSPs) and ASPs in pain experience, physical function, pain coping, and pain catastrophizing.Methods: Children with quantitative sensory testing data were selected from a larger study that examined pain and symptoms in children with SCD. Comparisons were made between children with NSP (n = 35; 13.9 ± 1.9 years) and ASP (n = 13; 12.8 ± 1.9 years). Children completed the Adolescent Pediatric Pain Tool, Functional Disability Inventory, Pain Coping Questionnaire, and Pain Catastrophizing Scale.Results: No significant differences were found in pain intensity (2.9 ± 3.0 vs. 2.6 ± 2.8 on 0-10 Visual Analogue Scale) between the NSP and ASP, respectively. The most common marked pain sites for both groups were lower extremities (22.9%), head and neck (20.8%), and upper extremities (20.8%). Functional Disability Inventory scores were significantly worse in ASP (38.5%) compared with NSP (11.4%). The ASP group had significantly worse scores in emotion-focused pain coping subscales.Conclusion: Children with SCD with ASP had worse functional disability, were expressing more affective pain quality, and had emotion-focused pain coping compared with NSP. Future studies are needed to examine the effectiveness of physical activities on the physical function as well as psychosocial interventions such as peer support and creative arts expression to minimize development of ASP in children with SCD.

• Intensive exercise in the early postoperative rehabilitation after hip fracture (up to 3 months postoperatively) is beneficial to the recovery of physical function in older adults. • Intensive exercise with more load lead to greater improvements in muscle strength, balance, and functional ability. • Older adults with cognitive impairment were not included in the studies selected for this review, conclusions about the training results may not be extended to this population. Individuals commonly experience age-related systemic decreases in skeletal muscle strength, physical function, and mobility, leading to falls and potential associated hip fractures. To evaluate whether intensive exercise can improve physical function, mobility, and independence in activities of daily living (ADL) and shorten the length of hospital stay in older adults after hip fracture surgery. This systematic review was conducted under the PRISMA guidelines. Searches were performed on January 5, 2022 in eight databases. Randomized controlled trials (RCTs) were included. The participants included older adults with hip fracture, and the intervention studied was intensive exercise. The outcomes were physical function, mobility, ADLs, and the length of hospital stay. Meta-analyses were conducted using RevMan 5.3. Fifteen studies were included in this review. After hip fracture surgery, intensive exercise improved participants' physical function to a greater extent than regular or no exercise (standardized mean difference [SMD] = 0.74; 95% CI: 0.25, 1.23). Intensive exercise was particularly more effective for gait speed (SMD = 0.15, 95% CI: 0.01, 0.30), the timed up-and-go test results (mean difference [MD] = -4.34, 95%CI: -6.74, -1.94), balance (SMD =0.42, 95% CI: 0.38, 0.89), and ADLs (SMD = 0.55, 95% CI: 0.24, 0.87). The quality of the evidence was low due to risk of bias, inconsistency, and imprecision. Intensive exercise early post-operation provides potential additional benefits compared to no or regular exercises on older adults after hip fracture surgery. [ABSTRACT FROM AUTHOR]

[Display omitted] • Pulmonary function and physical function are often impaired in childhood cancer. • Patients with pulmonary dysfunction are often asymptomatic. • Physical function testing could unmask impairments undetectable by screening. • There is a gap in the literature in diaphragm function in childhood cancer. • Pulmonary function tests could be augmented by inspiratory muscle testing. Children with cancer experience pulmonary and physical function side effects from the cancer itself and the medical interventions. This systematic review examines the known relationship between pulmonary function and physical function in childhood cancer and identifies gaps in the literature. A search of Ovid Medline, CINAHL (EbscoHost) and Embase to identify literature from 2009 to March 2020. Fifty-seven studies met inclusion criteria. Thirty-seven studies reported impaired pulmonary function. Incidence of pulmonary dysfunction ranged from 45.5 % to 84.1 %. Eighteen studies reported impaired physical function. Three studies investigated the relationship between pulmonary function and physical function. No studies explored inspiratory muscle strength. Pulmonary function and physical function are related and frequently impaired in children during and after cancer treatment. A literature gap was found in diaphragm function and its relationship with physical function. Future studies should focus on interventions that target the pulmonary mechanisms impacting physical function. [ABSTRACT FROM AUTHOR]
