- Poor reporting of medical and healthcare systematic reviews is a problem from which the sports and exercise medicine, musculoskeletal rehabilitation, and sports science fields are not immune. Transparent, accurate and comprehensive systematic review reporting helps researchers replicate methods, readers understand what was done and why, and clinicians and policy-makers implement results in practice. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement and its accompanying Explanation and Elaboration document provide general reporting examples for systematic reviews of healthcare interventions. However, implementation guidance for sport and exercise medicine, musculoskeletal rehabilitation, and sports science does not exist. The Prisma in Exercise, Rehabilitation, Sport medicine and SporTs science (PERSiST) guidance attempts to address this problem. Nineteen content experts collaborated with three methods experts to identify examples of exemplary reporting in systematic reviews in sport and exercise medicine (including physical activity), musculoskeletal rehabilitation (including physiotherapy), and sports science, for each of the PRISMA 2020 Statement items. PERSiST aims to help: (1) systematic reviewers improve the transparency and reporting of systematic reviews and (2) journal editors and peer reviewers make informed decisions about systematic review reporting quality.

- OBJECTIVE: The objective was to explore family caregivers' perspectives of the recovery process of older adults with hip fracture and describe experiences from caregivers who: (1) used the online intervention, or (2) received home-based care provided by the Andalusian Public Health Care System. METHODS: This was an exploratory secondary study with informal family caregivers who had an older adult family member with hip fracture enrolled in a novel telerehabilitation (telerehab) clinical trial. Forty-four caregivers of older adults with hip fracture were interviewed at 6 to 9months after their family member's hip fracture. RESULTS: Caregivers shared concerns of family members' survival and recovery; they recounted increased stress and anxiety due to the uncertainty of new tasks associated with providing care and the impact on their lifestyle. Although most caregivers were satisfied with the health care received, they made suggestions for better organization of hospital discharge and requests for home support. The main reasons why caregivers and their family member chose the telerehab program were to enhance recovery after fracture, gain knowledge for managing at home, and because of the convenience of completing the exercises at home. There were more family caregivers in the control group who expressed a high level of stress and anxiety, and they also requested more social and health services compared with caregivers whose family member received telerehab. CONCLUSION: Family caregivers are an essential component of recovery after hip fracture by providing emotional and physical support. However, future clinical interventions should evaluate person-centered interventions to mitigate possible stress and anxiety experienced by family caregivers. IMPACT: Family caregivers' perspectives are necessary in the co-design of management strategies for older adults after hip fracture. © The Author(s) 2020.

- Background: We previously selected four strains of Saccharomyces cerevisiae for their ability to produce the aquaporin Fps1 in sufficient yield for further study. Yields from the yeast strains spt3 Delta, srb5 Delta, gcn5 Delta. and yTHCBMS1 (supplemented with 0.5 mu g/mL doxycycline) that had been transformed with an expression plasmid containing 249 base pairs of 5' untranslated region (UTR) in addition to the primary FPS1 open reading frame (ORF) were 10-80 times higher than yields from wild-type cells expressing the same plasmid. One of the strains increased recombinant yields of the G protein-coupled receptor adenosine receptor 2a (A(2a)R) and soluble green fluorescent protein (GFP). The specific molecular mechanisms underpinning a high-yielding Fps1 phenotype remained incompletely described. Results: Polysome profiling experiments were used to analyze the translational state of spt3 Delta, srb5 Delta, gcn5 Delta. and yTHCBMS1 (supplemented with 0.5 mu g/mL doxycycline); all but gcn5 Delta. were found to exhibit a clear block in translation initiation. Four additional strains with known initiation blocks (rpl31a Delta., rpl22a Delta., ssf1 Delta. and nop1 Delta.) also improved the yield of recombinant Fps1 compared to wild-type. Expression of the eukaryotic transcriptional activator GCN4 was increased in spt3 Delta, srb5 Delta, gcn5 Delta. and yTHCBMS1 (supplemented with 0.5 mu g/mL doxycycline); these four strains also exhibited constitutive phosphorylation of the eukaryotic initiation factor, eIF2 alpha. Both responses are indicative of a constitutively-stressed phenotype. Investigation of the 5' UTR of FPS1 in the expression construct revealed two untranslated ORFs (uORF1 and uORF2) upstream of the primary ORF. Deletion of either uORF1 or uORF1 and uORF2 further improved recombinant yields in our four strains; the highest yields of the uORF deletions were obtained from wild-type cells. Frame-shifting the stop codon of the native uORF (uORF2) so that it extended into the FPS1 ORF did not substantially alter Fps1 yields in spt3. or wild-type cells, suggesting that high-yielding strains are able to bypass 5' uORFs in the FPS1 gene via leaky scanning, which is a known stress-response mechanism. Yields of recombinant A2aR, GFP and horseradish peroxidase could be improved in one or more of the yeast strains suggesting that a stressed phenotype may also be important in high-yielding cell factories. Conclusions: Regulation of Fps1 levels in yeast by translational control may be functionally important; the presence of a native uORF (uORF2) may be required to maintain low levels of Fps1 under normal conditions, but higher levels as part of a stress response. Constitutively-stressed yeast strains may be useful high-yielding microbial cell factories for recombinant protein production.

- BACKGROUND: Inbred individuals reared in controlled environments display considerable variance in many complex traits but the underlying cause of this intangible variation has been an enigma. Here we show that two modifiers of epigenetic gene silencing play a critical role in the process.RESULTS: Inbred mice heterozygous for a null mutation in DNA methyltransferase 3a (Dnmt3a) or tripartite motif protein 28 (Trim28) show greater coefficients of variance in body weight than their wild-type littermates. Trim28 mutants additionally develop metabolic syndrome and abnormal behavior with incomplete penetrance. Genome-wide gene expression analyses identified 284 significantly dysregulated genes in Trim28 heterozygote mutants compared to wild-type mice, with Mas1, which encodes a G-protein coupled receptor implicated in lipid metabolism, showing the greatest average change in expression (7.8-fold higher in mutants). This gene also showed highly variable expression between mutant individuals.CONCLUSIONS: These studies provide a molecular explanation of developmental noise in whole organisms and suggest that faithful epigenetic control of transcription is central to suppressing deleterious levels of phenotypic variation. These findings have broad implications for understanding the mechanisms underlying sporadic and complex disease in humans.
