Results of a Community-Based Screening Program for Chlamydia trachomatis Genital Infection in Young People Aged 18-25 Years.

Introduction and aim (CT) cases have increased in the last decade. The aim of the study was to assess the prevalence of CT genital infection in asymptomatic, sexually active young people and determine whether a community screening program would be effective in reducing the number of cases. Methods A descriptive cross-sectional studyof consecutive inclusion of asymptomatic people aged 18-25 years between September 2021 and May 2022.

Does short-term, airborne lead exposure during pregnancy affect birth outcomes? Quasi-experimental evidence from NASCAR's deleading policy.

Background: There is evidence of a weak placental-fetal barrier to lead, suggesting that maternal lead exposure could affect the fetus. The health consequences for newborns from in utero lead exposure are not well understood.

Objectives: We estimated the effects by trimester, of short-term (<1 week), airborne lead exposure during pregnancy on birth outcomes.

Right pulmonary artery to left atrial fistula: a description of two cases, emphasising a diagnostic approach.

Right pulmonary artery to left atrial fistula is a rare pathology characterised by a right to left shunt. Another important aspect of this pathology is the difficulty encountered in making a diagnosis, which is why the diagnosis is frequently delayed into adulthood. A description of two cases is used to emphasise the importance of the different modes of echocardiography as a diagnostic tool in diagnosis, as well as the two different clinical forms that it adopts: a group of patients suffering cardiac failure and cyanosis without apparent cause generally in neonates and a second group of mostly older patients with dyspnoea and cyanosis without apparent cause.
