A retrospective study of prostate-specific antigen and international prostate symptoms scores from participants at a men's health screening initiative in Trinidad.

Background: This study describes the characteristics of men attending a primary health care screening initiative, determines the proportion of men who have elevated International Prostate Symptom Score (IPSS) scores and prostate-specific antigen (PSA) levels, and determines any correlation between these scores as indicators for benign prostatic hyperplasia (BPH) or prostate cancer.

Methods: Data were collected from all patient records during men's health screening initiatives that occurred in December 2018, January 2019, and March 2019 in Trinidad and Tobago. A total of 350 medical records were analyzed to record patient demographics, PSA levels, and IPSS scores.

Age-Related Susceptibility of Turkeys to Enteric Viruses.

Several different enteric viruses have been identified as the causes of gastrointestinal infections in poultry. Enteric virus infections are well characterized in poults, but limited studies have been conducted in older birds. The susceptibility of 2-, 7-, 12-, 30-, and 52-wk-old turkeys to turkey coronavirus (TCoV) and turkey astrovirus (TAstV) was evaluated, as well as the effect of combined infection of TAstV and TCoV in 2-wk-old poults and turkey hens.

Effect of coronavirus infection on reproductive performance of turkey hens.

Turkey coronavirus (TCoV) infection causes enteritis in turkeys of varying ages with high mortality in young birds. In older birds, field evidence indicates the possible involvement of TCoV in egg-production drops in turkey hens. However, no experimental studies have been conducted to demonstrate TCoV pathogenesis in turkey hens and its effect on reproductive performance.

Replication of swine and human influenza viruses in juvenile and layer turkey hens.

Since the first reported isolation of swine influenza viruses (SIVs) in turkeys in the 1980s, transmission of SIVs to turkeys was frequently documented. Recently, the 2009 pandemic H1N1 virus, that was thought to be of swine origin, was detected in turkeys with a severe drop in egg production. In this study, we assessed the infectivity of different mammalian influenza viruses including swine, pandemic H1N1 and seasonal human influenza viruses in both juvenile and layer turkeys.
