Objective: To describe the impact of the new intervention model implemented by Paraguay across five districts of the Central Region in the last quarter of 2023, consisting of an integrated health services-based strategy to recover coverage with the tracer vaccine (pentavalent until April 2023, hexavalent thereafter) in children under 1 year of age; and the measles, mumps, and rubella (MMR) vaccine for the 1-year-old population.

Methods: Descriptive, cross-sectional study with comparative analysis before (epidemiological weeks [EW] 1 and 34 of 2023) and after (EW35 and EW52 of 2023) the intervention. Three indicators were assessed: a) coverage with all three doses of pentavalent or hexavalent vaccine and first and second doses of MMR; b) productivity, represented by third doses of pentavalent or hexavalent vaccine administered; and c) dropout rates for the pentavalent or hexavalent and MMR vaccines.

Article Synopsis
  • Obstructive sleep apnea (OSA) significantly impacts cardiovascular event recurrence in patients with acute coronary syndrome (ACS), particularly in those without prior cardiovascular disease.
  • The study identified two groups based on the severity of OSA and utilized proteomics to analyze plasma proteins, revealing 24 differentially expressed proteins associated with OSA severity.
  • Bioinformatic analysis suggested that these proteins are involved in key molecular pathways related to immune function, cell signaling, and inflammation, linking OSA to adverse cardiovascular outcomes.

Introduction: Among all patients with hypertension, those with resistant hypertension (RH) have the highest rates of subclinical organ damage (SOD). The prevalence of obstructive sleep apnea (OSA) is high in RH patients, and it could contribute to SOD. We aimed to investigate how OSA and its treatment are related to SOD in a large cohort of RH patients.

The increase in migratory flows worldwide has led to the creation of detention centers as a form of control of irregular migration. Recipient countries are responsible for protecting detainees' right to mental health, but the literature suggests that immigration detention centers are environments associated with complex mental health needs among the detainees. This study aims to approach the mental health of people detained in the immigration detention centers in Spain, a southern border of Europe.

Article Synopsis
  • A non-dipping blood pressure pattern in patients with obstructive sleep apnea (OSA) is linked to increased cardiovascular risk, but the mechanisms are poorly understood.
  • Researchers conducted a study analyzing blood metabolites and lipids in adults with suspected OSA, using polysomnography (PSG) to classify patients into dippers and non-dippers based on their blood pressure patterns.
  • They identified 44 unique plasma compounds associated with non-dipping BP, revealing potential metabolic and biological pathways that may underlie the irregular circadian BP rhythms in OSA patients and impacted by CPAP treatment over time.

Background: School-based law enforcement (SBLE) has become a common intervention. Although SBLE is meant to make schools safer, critics suggest it may not accomplish this purpose, and may have unintended negative consequences such as increasing students' exclusionary discipline or contact with the criminal justice system. There may also be secondary effects related to perceptions of the school or student learning.
