Background: Research examining the association between physical activity (PA) and prostate cancer (PCa) has accumulated; however, few studies have examined this association in the context of active surveillance. The current study examines this among men initially diagnosed with favorable-risk PCa and managed by active surveillance at Sunnybrook Health Sciences Centre in Canada and the Royal Marsden Hospital in the United Kingdom.
Methods: Participants completed a questionnaire on daily participation in non-leisure, transport, and recreational PA. A logistic regression was employed using PA as the independent variable and whether the patient reclassified to higher-risk PCa while on active surveillance as the dependent variable. Demographic and lifestyle covariates were incorporated in the analysis to assess potential confounding and effect modification.
Results: Men from both hospitals presented with similar clinical and demographic characteristics. Total PA was inversely associated with odds of reclassification while on active surveillance (p-trend = 0.027). A weaker inverse association was observed with recreational PA (p-trend = 0.30). Men who participated in weekly vigorous PA were less likely to reclassify than those who did not (odds ratio (95% confidence interval): 0.42 (0.20-0.85)).
Conclusions: Total and vigorous PA were inversely associated with odds of reclassification in two active surveillance cohorts. Given the limitations of this study, more robust prospective observational studies involving objective PA measures are warranted to confirm findings.

Objective: We sought to determine, in a prospective long term cohort, the prognostic value of negative MR imaging with respect to upgrading and need for intervention in men on AS.
Method: A long term prospective single centre study of men on Active surveillance with MR imaging. Primary outcome was upgrading on biopsy and rate of intervention.

Background: Illness severity, comorbidity, fever, age and symptom duration influence antibiotic prescribing for respiratory tract infections (RTI). Non-medical determinants, such as patient expectations, also impact prescribing.
Aim: To quantify the effect of general practitioners' (GPs') perception of a patient request for antibiotics on antibiotic prescribing for RTI and investigate effect modification by medical determinants and country.

Hepatitis E virus (HEV) is the most common cause of acute viral hepatitis, responsible for large outbreaks in resource limited countries. The virus belongs to the genus Orthohepevirus which is subdivided into eight distinct genotypes (HEV-1 to HEV-8). Human disease transmission is mostly through the faecal-oral route.

Summary: Craniopharyngiomas (CPs) are rare brain epithelial tumours arising in the suprasellar region, infiltrating adjacent areas causing visual loss, panhypopituitarism, cognitive deficits and morbid obesity. Papillary CPs (PCPs) harbour in 94% BRAF mutation cases. Two patients with PCP and BRAF V600E mutations but with different tumour status were treated with BRAF and MEK inhibitors.

Background: With rising well-differentiated thyroid cancer (WDTC) incidence, the appropriate treatment choice remains controversial for T1 tumors <2 cm. This study analyzed differences in surgery refusal and survival outcomes between T1a (<1 cm) and T1b (1-2 cm) WDTC, examining the demographic and clinical characteristics associated with patients who decide to either undergo or refuse recommended surgery.
Methods: We studied 81,664 T1N0M0 WDTC patients in the Surveillance, Epidemiology, and End Results (SEER) registry [2000-2019].
