J Racial Ethn Health Disparities
December 2024
Article Synopsis
- This study is a scoping review that examines the health needs of racialized men in sex work, utilizing the Social Determinants of Health model to map existing literature.
- The review identifies major health vulnerabilities influenced by individual factors more than social support systems and community frameworks.
- The findings emphasize the importance of adopting a structural approach to address health disparities, advocating for interventions that go beyond blaming individual behaviors.
Article Synopsis
- - The study focused on evaluating blood donor eligibility and infectious disease screening in Latin American countries, as there was limited information available on this topic.
- - An international team created a 16-question survey and received responses from 82 blood donor institutions across 14 Latin American nations, revealing that most donor centers have a deferral rate of 5-25% primarily due to low hemoglobin and high-risk behaviors.
- - The results highlighted that while most centers performed serologic tests for infectious diseases like HIV and Hepatitis, there was a lack of uniformity in donor selection processes and screening practices throughout the region.

Objectives: Glottic tumors with infiltration of the anterior/posterior commissure, and lesions with subglottic, cricoid, or cricoarytenoid joint infiltration have been highly controversial in the past, from the perspective of oncological safety. Although conservation laryngeal resection options exist, most are limited by the extent of resection proscribed by the technique and the postoperative functional results. Oncologically speaking, extended vertical hemilaryngectomy is often the optimal solution.

Patients And Methods: We obtained pulse wave velocity (24-h PWV) by means of ambulatory blood pressure monitoring (ABPM) in patients with a recent small subcortical infarct (RSSI). Patients with known cardiac or arterial embolic sources were excluded.
Due to the propagation characteristics in the 2.5 GHz band, the signal is significantly degraded by building entry loss (BEL), making coverage in indoor environments in some cases non-existent. Signal degradation inside buildings is a challenge for planning engineers, but it can be seen as a spectrum usage opportunity for a cognitive radio communication system.
