Male-Pattern Vertex Baldness Trajectories, Chest Hair Patterns, and Odds of Overall and Aggressive Prostate Cancer.

Background: The link between hormones and hair growth is well established. Inconsistent associations have been found between hair patterns and cancer of the prostate, a hormone-dependent organ. We assessed vertex baldness trajectories, chest hair amount, and their relationships with the odds of developing prostate cancer in a large case-control study in Montreal, Canada.

Neighbourhood social deprivation and risk of prostate cancer.

Background: Striking geographic variations in prostate cancer incidence suggest an aetiological role for spatially-distributed factors. We assessed whether neighbourhood social deprivation, which can reflect limited social contacts, unfavourable lifestyle and environmental exposures, is associated with prostate cancer risk.

Methods: In 2005-2012, we recruited 1931 incident prostate cancer cases and 1994 controls in a case-control study in Montreal, Canada.

Family structure and living arrangements as indicators of social isolation, and prostate cancer risk.

Social isolation has been linked to a poorer prostate cancer prognosis. Little is known about how it could also influence its incidence. We investigated the association between family structure and living arrangements as potential indicators of social isolation, and prostate cancer risk, globally and according to disease aggressiveness.

A scoping review of social relationships and prostate cancer screening.

According to current US recommendations, the choice to undergo screening for prostate cancer should be an individual one, after considering with a clinician the balance of harms and benefits, and the values and preferences in the decision. Social relationships may influence such a decision. The purpose of this scoping review was to map the evidence on the association between social relationships and prostate cancer screening in the epidemiological literature and to highlight gaps in knowledge.

Marital status and prostate cancer incidence: a pooled analysis of 12 case-control studies from the PRACTICAL consortium.

While being in a committed relationship is associated with a better prostate cancer prognosis, little is known about how marital status relates to its incidence. Social support provided by marriage/relationship could promote a healthy lifestyle and an increased healthcare seeking behavior. We investigated the association between marital status and prostate cancer risk using data from the PRACTICAL Consortium.

Effect of Hydrocortisone on Mortality and Organ Support in Patients With Severe COVID-19: The REMAP-CAP COVID-19 Corticosteroid Domain Randomized Clinical Trial.

Importance: Evidence regarding corticosteroid use for severe coronavirus disease 2019 (COVID-19) is limited.

Objective: To determine whether hydrocortisone improves outcome for patients with severe COVID-19.

Design, Setting, And Participants: An ongoing adaptive platform trial testing multiple interventions within multiple therapeutic domains, for example, antiviral agents, corticosteroids, or immunoglobulin.

Association between Bacillus Calmette-Guerin (BCG) vaccination and lymphoma risk: A systematic review and meta-analysis.

Lymphoma etiology remains ill-defined, but immune factors seem to play a major role. The Bacillus Calmette-Guérin (BCG) vaccine, a non-specific stimulator of the cellular immune response, could influence lymphoma risk. Previous studies addressing this issue showed conflicting results.
