Background: Age at thelarche has decreased over recent decades. This change in female puberty timing may be influenced by exposure to endocrine disrupting chemicals (EDCs) during critical periods of development.
Objective: To review the scientific literature for evidence on the association of exposure to EDCs and other environmental chemicals with the timing of thelarche in girls.
Article Synopsis
- A meta-analysis of 7 clinical trials was conducted to evaluate the effectiveness of cardiac resynchronization therapy (CRT) in patients with nonischemic cardiomyopathy (NICM) compared to ischemic cardiomyopathy (ICM).
- The study included data from 6,252 patients, revealing that CRT significantly improved survival time and reduced hospitalizations for heart failure, regardless of the type of cardiomyopathy.
- While CRT showed greater echocardiographic improvements in patients with NICM, the overall cardiac benefits were found to be similar across both types of cardiomyopathy.
Based on toxicological evidence, children's exposure to phthalates may contribute to altered neurodevelopment and abnormal regulation of brain-derived neurotrophic factor (BDNF). We analyzed data from five aligned studies of the Human Biomonitoring for Europe (HBM4EU) project. Ten phthalate metabolites and protein BDNF levels were measured in the urine samples of 1148 children aged 6-12 years from Italy (NACII-IT cohort), Slovakia (PCB-SK cohort), Hungary (InAirQ-HU cohort) and Norway (NEBII-NO).

- - The study aimed to evaluate the effectiveness of cardiac resynchronization therapy (CRT) in patients with severe heart failure, particularly comparing those with New York Heart Association (NYHA) functional classes III and IV at the time of receiving the therapy.
- - Using a meta-analysis of data from multiple clinical trials (MIRACLE, MIRACLE-ICD, and COMPANION), researchers found that CRT was associated with a longer time before heart failure hospitalization or death, with no significant difference in outcomes between NYHA III and IV patients.
- - The analysis, which included data from 2309 patients, used advanced statistical models to assess outcomes and confirmed that associating CRT with improved survival and hospitalization rates was consistent across both functional
Complications in Patients with Surgically Altered Gastrointestinal Anatomy Undergoing Endoscopic Retrograde Cholangiopancreatography: 15-Year Experience at a Tertiary Care Center in Latin America.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is a common procedure, but it poses challenges in patients with surgically altered gastrointestinal anatomy (SAGA). Alternative techniques like single-balloon enteroscopy (SBE), double-balloon enteroscopy (DBE), or push enteroscopy (PE) have been used, albeit with potential complications. Limited Latin American data exists on ERCP complications in SAGA patients.
