Clinical outcomes and risk factors for immune recovery and all-cause mortality in Latin Americans living with HIV with virological success: a retrospective cohort study.

Introduction: Immune reconstitution following antiretroviral therapy (ART) initiation is crucial to prevent AIDS and non-AIDS-related comorbidities. Patients with suppressed viraemia who fail to restore cellular immunity are exposed to an increased risk of morbidity and mortality during long-term follow-up, although the underlying mechanisms remain poorly understood. We aim to describe clinical outcomes and factors associated with the worse immune recovery and all-cause mortality in people living with HIV (PLWH) from Latin America following ART initiation.

[Restless sleep disorder a new entity to considered in children].

Restless sleep disorder (RSD) is a condition recently described by a group of sleep experts who developed diagnostic and polysomnographic criteria after conducting a comprehensive review of the available literature where poor sleep or restless sleep is a symptom alone or that accompanies other disorders. This group defined RSD as a condition characterized by parental complaints of frequent jerking movements during sleep, position changes, and sleep disruption that cause significant impairment during the day. Diagnostic criteria include the presence of symptoms for at least 3 months, 3 times a week, and at least 5 movements per hour on polysomnography.

Genotype and Phenotype Characterization of Patients with Mucopolysaccharidosis IV-A in Chile.

Introduction: Morquio syndrome or mucopolysaccharidosis type IV-A (MPS IV-A) is an autosomal recessive disease caused by biallelic variants in the gene, encoding the lysosomal enzyme GalN6S, responsible for glycosaminoglycan keratan sulfate and chondroitin-6-sulfate degradation. Studies have shown that the degree of evolutionary and chemical divergence of missense variants in GalN6S when compared to ancestral amino acids is associated with the severity of the syndrome, suggesting a genotype-phenotype correlation. There is little information on Latin American patients with MPS IV-A that replicate these findings.

ClinPrior: an algorithm for diagnosis and novel gene discovery by network-based prioritization.

Background: Whole-exome sequencing (WES) and whole-genome sequencing (WGS) have become indispensable tools to solve rare Mendelian genetic conditions. Nevertheless, there is still an urgent need for sensitive, fast algorithms to maximise WES/WGS diagnostic yield in rare disease patients. Most tools devoted to this aim take advantage of patient phenotype information for prioritization of genomic data, although are often limited by incomplete gene-phenotype knowledge stored in biomedical databases and a lack of proper benchmarking on real-world patient cohorts.

Modifications in family centered developmental care and in neonatal intensive care during the COVID-19 pandemic in a hospital in Spain: A qualitative study.

Long-Term Benefits from Early Antiretroviral Therapy Initiation in HIV Infection.

Background: For people with HIV and CD4 counts >500 cells/mm, early initiation of antiretroviral therapy (ART) reduces serious AIDS and serious non-AIDS (SNA) risk compared with deferral of treatment until CD4 counts are <350 cells/mm. Whether excess risk of AIDS and SNA persists once ART is initiated for those who defer treatment is uncertain.

Methods: The Strategic Timing of AntiRetroviral Treatment (START) trial, as previously reported, randomly assigned 4684 ART-naive HIV-positive adults with CD4 counts .

Characteristics of psychosocial interventions to improve ART adherence in people living with HIV: A systematic review.

The HIV/AIDS pandemic continues to be a significant global public health crisis. The main HIV/AIDS treatment is the antiretroviral therapy (ART), which is highly effective but depends on the patient's adherence to be successful. However, the adherence to antiretroviral therapy remains unsatisfactory across different populations, which raises considerable difficulties at both individual and collective levels.

Consensus on complementary feeding from the Latin American Society for Pediatric Gastroenterology, Hepatology and Nutrition: COCO 2023.

Complementary feeding (CF) is defined as the feeding of infants that complements breastfeeding, or alternatively, feeding with a breast milk substitute, and is a process that is more than simply a guide as to what and how to introduce foods. The information provided by healthcare professionals must be up-to-date and evidence-based. Most of the recommendations that appear in the different international guidelines and position papers are widely applicable, but some must be regionalized or adapted to fit the conditions and reality of each geographic zone.
