Introduction Methods Consumer and Community Involvement Results Conclusion PLAIN LANGUAGE SUMMARY COVID‐19 caused significant occupational disruption to people's life roles, with some people requiring an inpatient rehabilitation admission. Occupational therapists assessed and treated these patients using previous knowledge of similar conditions due to limited specificity in available guidelines to inform practice. The aim of this study was to investigate current practice with post‐acute COVID‐19 (PAC) patients within an inpatient rehabilitation setting in Australia, to better understand the role and impact of occupational therapy.A mixed‐method study was conducted, including electronic medical record audits (October 2021 October 2022) and descriptive patient interviews at a large metropolitan subacute service. Descriptive statistics and qualitative analysis were used to summarise and interpret data.No involvement.A total of 24 patient electronic medical records were audited, and 10 patient interviews were completed. Three overarching categories were identified within the 685 occasions of occupational therapy service audited—occupational engagement, education provision and discharge planning. Patients identified the value of occupational therapy by reflecting on their lived experiences of engaging with occupational therapists and associated changes in occupational performance between COVID‐19 diagnoses and discharge home.Occupational therapists possess a unique skill set that directly addresses the occupational needs and priorities of PAC patients. This study adds to the growing body of evidence supporting the contribution of occupational therapy to the management of COVID‐19; however, further research is needed to develop evidence‐based practice resources and advocate for system changes that improve quality of life for COVID‐19 patients.During the COVID‐19 pandemic, a lot of people got very sick. Some of these people needed more time and support to get better. Occupational therapists were important during this time because they helped these people to do their daily activities again. Because there were not many resources on how to do this, we looked into what occupational therapists were doing to help these people. We looked at patient hospital files and also talked to them to understand this better. We found that occupational therapists focused on three main areas: helping patients do activities that were important to them, teaching them about COVID‐19 and helping them plan to leave the hospital. This study shows that occupational therapists are skilled at helping people with COVID‐19. But more research is needed to make resources and also help with changing the healthcare system to further help people get better from COVID‐19. [ABSTRACT FROM AUTHOR]

Community screening for sarcopenia is complex, with barriers including access to specialized equipment and trained staff to conduct body composition, strength and function assessment. In the current study, self-reported dietary protein intake and physical activity (PA) in adults ≥65 years was assessed relative to sarcopenia risk, as determined by body composition, strength and physical function assessments, consistent with the European Working Group on Sarcopenia in Older People (EWGSOP) definition. Of those screened (n = 632), 92 participants (77% female) were assessed as being at high risk of developing sarcopenia on the basis of dietary protein intake ≤1 g∙kg−1∙day−1 [0.9 (0.7–0.9) g∙kg−1∙day−1] and moderate intensity physical activity <150 min.week−1. A further 31 participants (65% female) were defined as being at low risk, with both protein intake [1.2 (1.1–1.5) g∙kg−1∙day−1] and PA greater than the cut-off values. High-risk participants had reduced % lean mass [53.5 (7.8)% versus 54.8 (6.1)%, p < 0.001] and impaired strength and physical function. Notably, high-risk females exhibited greater deficits in lean mass and strength, with minimal differences between groups for males. In community-dwelling older adults, self-reported low protein intake and low weekly PA is associated with heightened risk for sarcopenia, particularly in older women. Future research should determine whether early intervention in older adults with low protein intake and PA attenuates functional decline. [ABSTRACT FROM AUTHOR]

Background: Neutrophilic asthma (NA) is a clinically important asthma phenotype, the cellular and molecular basis of which is not completely understood. Airway macrophages are long‐lived immune cells that exert important homeostatic and inflammatory functions which are dysregulated in asthma. Unique transcriptomic programmes reflect varied macrophage phenotypes in vitro. We aimed to determine whether airway macrophages are transcriptomically altered in NA. Methods: We performed RNASeq analysis on flow cytometry‐isolated sputum macrophages comparing NA (n = 7) and non‐neutrophilic asthma (NNA, n = 13). qPCR validation of RNASeq results was performed (NA n = 13, NNA n = 23). Pathway analysis (PANTHER, STRING) of differentially expressed genes (DEGs) was performed. Gene set variation analysis (GSVA) was used to test for enrichment of NA macrophage transcriptomic signatures in whole sputum microarray (cohort 1 ‐ controls n = 16, NA n = 29, NNA n = 37; cohort 2 U‐BIOPRED ‐ controls n = 16, NA n = 47, NNA n = 57). Results: Flow cytometry‐sorting significantly enriched sputum macrophages (99.4% post‐sort, 44.9% pre‐sort, p <.05). RNASeq analysis confirmed macrophage purity and identified DEGs in NA macrophages. Selected DEGs (SLAMF7, DYSF, GPR183, CSF3, PI3, CCR7, all p <.05 NA vs. NNA) were confirmed by qPCR. Pathway analysis of NA macrophage DEGs was consistent with responses to bacteria, contribution to neutrophil recruitment and increased expression of phagocytosis and efferocytosis factors. GSVA demonstrated neutrophilic macrophage gene signatures were significantly enriched in whole sputum microarray in NA vs. NNA and controls in both cohorts. Conclusions: We demonstrate a pathophysiologically relevant sputum macrophage transcriptomic programme in NA. The finding that there is transcriptional activation of inflammatory programmes in cell types other than neutrophils supports the concept of NA as a specific endotype. [ABSTRACT FROM AUTHOR]

Becoming a phenotypic male is ultimately determined by androgen-induced masculinization. Disorders of fetal masculinization, resulting in hypospadias or cryptorchidism, are common, but their cause remains unclear. Together with the adult-onset disorders low sperm count and testicular cancer, they can constitute a testicular dysgenesis syndrome (TDS). Although masculinization is well studied, no unifying concept explains normal male reproductive development and its abnormalities, including TDS. We exposed rat fetuses to either anti-androgens or androgens and showed that masculinization of all reproductive tract tissues was programmed by androgen action during a common fetal programming window. This preceded morphological differentiation, when androgen action was, surprisingly, unnecessary. Only within the programming window did blocking androgen action induce hypospadias and cryptorchidism and altered penile length in male rats, all of which correlated with anogenital distance (AGD). Androgen-driven masculinization of females was also confined to the same programming window. This work has identified in rats a common programming window in which androgen action is essential for normal reproductive tract masculinization and has highlighted that measuring AGD in neonatal humans could provide a noninvasive method to predict neonatal and adult reproductive disorders. Based on the timings in rats, we believe the programming window in humans is likely to be 8-14 weeks of gestation., Introduction In mammals, the reproductive system is initially indistinguishable between the two sexes but is predetermined to develop along the female pathway. To become a male requires modification of this [...]
