Article Abstract

Background: Although hepatitis C virus (HCV) infection is considered a relevant public health problem in Mexico, the prevalence is still under discussion. The objective of this study was to conduct a systematic review to explore the prevalence of HCV infection in the Mexican population.

Methods: A systematic review of studies reporting prevalence in Mexican population was performed using several free-access databases.

Results: Sixty-eight works fulfilled the search criteria. From these, 44 studies involved asymptomatic subjects and 28 involved patients or high-risk subjects. Prevalence of blood donors (6,955,558 persons) ranged from 0.0% to 2.05%, with 7/32 studies reporting values >1%, whereas prevalence of non-donor asymptomatic subjects (28,528 persons) from 0.0% to 2.7%, with 7/11 studies reporting values >1%, and medical personnel from 0.0% to 2.08% (1,227 persons), with 4/11 studies reporting values >1%. Prevalence of patients with chronic hepatic disease ranged from 6.7% to 77%. The most prevalent genotype was 1 (30.0-87.5%), of which subtype 1b is the most frequent (11.9-61.9%). The main risk factors were blood transfusion and unprotected sex or having multiple sex partners.

Conclusions: The prevalence in the Mexican population seems to be in accordance with that previously estimated by the World Health Organization (1-2.5%).

Background: Traumatic anterior shoulder dislocation is the most common type of joint dislocation, with an incidence of 11 to 29 per 100 000 persons per year. Controversy still surrounds the recommendations for treatment and the available procedures for surgical stabilization.

Methods: This review is based on pertinent publications (2014-2024) that were retrieved by a selective search in the PubMed and Google Scholar databases.

This study reports on the development of a highly sensitive non-enzymatic electrochemical sensor based on a two-dimensional TiCT/MWCNT-OH nanocomposite for the detection of paraoxon-based pesticide. The synergistic effect between the TiCT nanosheet and the functionalized multi-walled carbon nanotubes enhanced the sensor's conductivity and catalytic activity. The nanocomposite demonstrates superior electrochemical and electroanalytical performance compared to the pristine TiCT and MWCNT-OH in detecting paraoxon-ethyl in fruit samples (green and red grapes), with a linear response range from 0.

Since decades after temozolomide was approved, no effective drugs have been developed. Undoubtedly, blood-brain barrier (BBB) penetration is a severe issue that should be overcome in glioblastoma multiforme (GBM) drug development. In this research, we were inspired by linezolid through structural modification with several bioactive moieties to achieve the desired brain delivery.

Community health workers (CHWs) play a significant role in supporting health services delivery in communities with few trained health care providers. There has been limited research on ways to optimize the role of CHWs in HIV prevention service delivery. This study explored CHWs' experiences with offering HIV prevention services [HIV testing and HIV pre- and post-exposure prophylaxis (PrEP and PEP)] during three pilot studies in rural communities in Kenya and Uganda, which aimed to increase biomedical HIV prevention coverage via a structured patient-centered HIV prevention delivery model.

Importance: During buprenorphine treatment for opioid use disorder (OUD), risk factors for opioid relapse or treatment dropout include comorbid substance use disorder, anxiety, or residual opioid craving. There is a need for a well-powered trial to evaluate virtually delivered groups, including both mindfulness and evidence-based approaches, to address these comorbidities during buprenorphine treatment.

Objective: To compare the effects of the Mindful Recovery Opioid Use Disorder Care Continuum (M-ROCC) vs active control among adults receiving buprenorphine for OUD.
