Aims: The prevalence of hepatitis C virus (HCV) infection, risk factors and HCV genotypes in 140 HIV-1 infected individuals from northern Mexico was determined.
Methods: Hepatitis C infection was confirmed by the detection of anti-HCV antibodies and HCV-RNA in sera, and genotyping was performed by the InnoLiPA-HCV genotype assay.
Results: Seventeen (12.1%) out of 140 HIV-infected individuals were found to be HCV-positive. Coinfected individuals were more likely to be male (87%). The most frequent genotype was 1a (41%), followed by 1b (29.4%), 2a/c (17.6%), 2b (5.9%) and 3 (5.9%). Serum transaminase concentrations (AST and ALT) were higher in coinfected patients. Among the risk factors for coinfection: sexual transmission was the most frequently observed (men who have sex with men (MSM); 64.7% and bisexual behavior; 64.7%) followed by intravenous drug users (IVDU) (53%). There was no association of the HCV genotypes with the age and risk factors for HIV-1 and HCV infection observed in the studied patients.
Conclusion: The results suggest that the prevalence of HIV-1/HCV coinfection in Mexico is lower than in other American countries.

Objective: This study investigates the relationship between the albumin-to-creatinine ratio and diabetic retinopathy (DR) in US adults using NHANES data from 2009 to 2016. This study assesses the predictive efficacy of the urinary serum albumin-to-creatinine ratio (UACR/SACR Ratio) against traditional biomarkers such as the serum albumin-to-creatinine ratio (SACR) and urinary albumin-to-creatinine ratio (UACR) for evaluating DR risk. Additionally, the study explores the potential of these biomarkers, both individually and in combination with HbA1c, for early detection and risk stratification of DR.

Background And Aims: Inflammatory bowel disease (IBD) develops in genetically susceptible individuals exposed to certain environmental factors, of which only a few have been established. We aimed to assess whether bariatric surgery (BS) and severe obesity are associated with an increased risk of developing IBD.
Methods: Adults diagnosed with obesity or severe obesity between 2005 and 2020 were identified from the Catalan Health Surveillance System; those diagnosed with IBD prior to the diagnosis of obesity or severe obesity were excluded.

Purpose: To review hospitalized patients with Acute Retinal Necrosis (ARN) and investigate factors associated with subsequent retinal detachment (RD).
Study Design: Retrospective.
Methods: The study included 40 patients (42 eyes), categorized into non-RD (23 eyes) and RD (19 eyes) groups.
Pharmacologic Management of Heart Failure with Preserved Ejection Fraction (HFpEF) in Older Adults.

There are several pharmacologic agents that have been touted as guideline-directed medical therapy for heart failure with preserved ejection fraction (HFpEF). However, it is important to recognize that older adults with HFpEF also contend with an increased risk for adverse effects from medications due to age-related changes in pharmacokinetics and pharmacodynamics of medications, as well as the concurrence of geriatric conditions such as polypharmacy and frailty. With this review, we discuss the underlying evidence for the benefits of various treatments in HFpEF and incorporate key considerations for older adults, a subpopulation that may be at higher risk for adverse drug events.

Introduction: Therapeutic drug monitoring (TDM) in inflammatory rheumatic diseases (RMDs) is gaining interest. However, there are unresolved questions about the best practices for implementing TDM effectively in clinical settings.
Objective: The primary objective of this study was to evaluate whether early TDM of adalimumab predicts drug survival at 52 weeks in patients with RMDs.
