Hemiplegic patients are prone to bone loss and alterations in fat and lean mass, which ultimately affect their rehabilitation status and propensity in bone fractures. The present study aimed to evaluate body composition and bone mineral density (BMD) in stroke patients within 1st year post-stroke. Fifty-eight hemiplegic patients (36 men and 22 women) were enrolled in this prospective study. Dual-energy X-ray absorptiometry was used to assess total-body and lower-extremity BMDs (g/cm(2)), lean mass (g), and fat mass (g) after 3, 6 and 12 mo of stroke that led to hemiplegia. The Modified Ashworth Scale and the functional ambulation category were used to evaluate spasticity and ambulatory category of patients, respectively. Both sexes exhibited total-body and paretic lower-limb BMD loss, fat mass gain, and lean mass waste during the 1st 12 mo poststroke, and in most cases, statistically significant differences were found between 3 and 6 mo; however, the pattern of changes was different between males and females. Therefore, it is suggested that disability because of hemiplegia led to alterations in muscle function, which triggered skeletal and body composition changes and rendered these patients particularly prone to increased fracture risk.

Background: Tumour hypoxia resulting from inadequate perfusion is common in many solid tumours, including prostate cancer, and constitutes a major limiting factor in radiation therapy that contributes to treatment resistance. Emerging research in preclinical animal models indicates that exercise has the potential to enhance the efficacy of cancer treatment by modulating tumour perfusion and reducing hypoxia; however, evidence from randomised controlled trials is currently lacking. The 'Exercise medicine as adjunct therapy during RADIation for CAncer of the prostaTE' (ERADICATE) study is designed to investigate the impact of exercise on treatment response, tumour physiology, and adverse effects of treatment in prostate cancer patients undergoing external beam radiation therapy (EBRT).

Gut microbiota, which act as a determinant of pharmacokinetics, have long been overlooked. In recent years, a growing body of evidence indicates that the gut microbiota influence drug metabolism and efficacy. Conversely, drugs also exert a substantial influence on the function and composition of the gut microbiota.

Background: Previous studies showed airborne bacteria affect pneumonia incidence, but specific impacts of bacterial communities on Klebsiella pneumoniae infection were unknown.
Methods: Five different ratios of bacterial community structures were randomly generated. Mice were divided into control, artificial bacterial community exposure, and corresponding Klebsiella pneumoniae challenge groups.
Impact of exercise with blood flow restriction on muscle hypertrophy and performance outcomes in men and women.

Blood flow restriction training (BFRT) has been previously studied as an alternative form of resistance training to gain lean mass and improve performance outcomes. However, in all exercise studies of BFRT, the proportion of female participants represents only 17-29% of all research participants. This highlights a strong underrepresentation of females and the need for more knowledge on the impact of BFRT and sex differences.
