As the number of HIV/AIDS cases continues to increase among youth, aged 15-24 years, it becomes critically important to identify the factors that are contributing to this increase. Trends in perceived risk and risk behaviours were examined among youth by sex and age in an attempt to address this concern. National-level cross-sectional data across three time periods (1996, 2000, 2004) gathered from youths, aged 15-24 years in Jamaica for six outcomes were examined (perceived risk, ever had sex, initiation of sex before age 14, multiple sexual partnerships, condom use at last sex with regular and non-regular partners). Trend analyses were employed for each outcome for the total sample and separately by sex and age. A significant positive increase in condom use emerged; males reported higher levels of condom use at last sex with most recent regular partner (55.7% in 1996, 67.9% in 2004, p < 0.01). Condom use by females with regular and non-regular partners did not increase. There was no significant change in the percent of youths reporting multiple partnerships, the percent initiating sex or age at first sex. Youths did perceive themselves to be at greater risk for HIV in 2004 than in 1996 (40.0% vs. 17.6%, p < 0.001). These analyses revealed inadequate protective behaviour adoption by Jamaican youths. Prevention programs targeting youths need to be expanded significantly, be culturally relevant, and also address social vulnerability.

Background/aims: Certain sociodemographic groups are routinely underrepresented in clinical trials, limiting generalisability. Here, we describe the extent to which enriched enrolment approaches yielded a diverse trial population enriched for older age in a randomised controlled trial of a blood-based multi-cancer early detection test (NCT05611632).
Methods: Participants aged 50-77 years were recruited from eight Cancer Alliance regions in England.

Immunology advances have increased our understanding of autoimmune, auto-inflammatory, immunodeficiency, infectious, and other immune-mediated inflammatory diseases (IMIDs). Furthermore, evidence is growing for the immune involvement in aging, metabolic and neurodegenerative diseases, and different cancers. However, further research has indicated sex/gender-based immune differences, which further increase higher incidences of various autoimmune diseases (AIDs), such as systemic lupus erythematosus (SLE), myasthenia gravis, and rheumatoid arthritis (RA) in females.

High cardiac sympathetic drive and release of the sympathetic cotransmitter neuropeptide Y (NPY) are significant features of congestive heart failure (CHF), in which resting venous NPY levels are known to be associated with mortality. However, whether circulating NPY levels increase during exercise in CHF when they are already elevated is controversial. We sought to establish the dynamics of circulating NPY levels in CHF patients treated with contemporary medical therapy and devices in relationship to indices of performance linked to long-term prognosis.

Pityriasis rosea (PR) is a self-limited exanthem associated with the endogenous systemic reactivation of human herpesvirus (HHV)-6 and HHV-7. The disease typically begins with a single erythematous patch on the trunk (herald patch), followed by a secondary eruption of smaller papulosquamous lesions. Rarely, the herald patch may be the only cutaneous manifestation of PR.

Neurological manifestations associated with human parvovirus B19 (B19V) infections are rare and varied. Acute encephalitis and encephalopathy are the most common, accounting for 38.8% of all neurological manifestations associated with human B19V.
