Basic Science and Pathogenesis.

Background: Most research initiatives have emerged from high-income countries (HIC), leaving a gap in understanding the disease's genetic basis in diverse populations like those in Latin American countries (LAC). ReDLat tackles this gap, focusing on LAC's unique genetics and socioeconomic factors to identify specific Alzheimer's Disease (AD) and Frontotemporal Dementia (FTD) risk factors in Mexico, Colombia, Peru, Chile, Argentina, and Brazil.

Method: We employed a comprehensive genetic analysis approach, integrating Whole Genome Sequencing (WGS), Exome Sequencing, and SNP arrays to understand the cohort's unique genetic architecture.

Cluster analysis of symptoms and assessment of caregiver reports in pediatric foreign bodies.

Foreign body (FB) ingestion and aspiration are frequent causes of pediatric emergency room visits, with significant morbidity and mortality risks. This cross-sectional study analyzed 1,052 pediatric patients admitted for suspected FB events at a single institution between 2008 and 2015, including 886 cases of suspected ingestion and 166 cases of suspected aspiration. Cluster analysis identified three distinct clusters for both groups, with respiratory symptoms being predominant in clusters with worse outcomes.

Rationale and design of the beta-blockers in tako-tsubo syndrome study: a randomized clinical trial (β-Tako).

Unlabelled: Introduction y objectives: Tako-tsubo syndrome (TTS) is a cardiac condition that mimics acute coronary syndrome, characterized by transient left ventricular dysfunction in the absence of culprit coronary artery stenosis. Although its etiology remains unknown, reversible microvascular dysfunction secondary to an adrenergic surge is thought to play a role. Treatment is empirical, although most patients receive beta-blockers (BB) in clinical practice.

Ecological and anthropogenic effects on the genomic diversity of lemurs in Madagascar.

Ecological variation and anthropogenic landscape modification have had key roles in the diversification and extinction of mammals in Madagascar. Lemurs represent a radiation with more than 100 species, constituting roughly one-fifth of the primate order. Almost all species of lemurs are threatened with extinction, but little is known about their genetic diversity and demographic history.

Structural inequality linked to brain volume and network dynamics in aging and dementia across the Americas.

Structural inequality, the uneven distribution of resources and opportunities, influences health outcomes. However, the biological embedding of structural inequality in aging and dementia, especially among underrepresented populations, is unclear. We examined the association between structural inequality (country-level and state-level Gini indices) and brain volume and connectivity in 2,135 healthy controls, and individuals with Alzheimer's disease and frontotemporal lobe degeneration from Latin America and the United States.

Serum 25-Hydroxyvitamin D Levels and Disease Activity in Patients with Systemic Lupus Erythematosus: An Exploratory Study in Western Mexico.

Background And Objectives: The correlation between diminished 25-hydroxyvitamin D (25-(OH)D) concentrations and heightened disease activity in systemic lupus erythematosus (SLE) patients remains contentious, as clinical studies have yielded conflicting outcomes-some propose a potential link, while others assert no relationship exists. Nonetheless, all studies report a significant prevalence of low 25-(OH)D levels among SLE patients. This study aimed to assess the frequency of low serum levels of 25-(OH)D in Mexican patients with SLE and to evaluate the correlation between 25-(OH)D deficiency or insufficiency and disease activity levels.

Evidence-based clinical standard for the diagnosis and treatment of candidemia in critically ill patients in the intensive care unit.

Candidemia is the predominant form of invasive candidiasis and the most frequently occurring serious fungal infection in critically ill patients in Intensive Care Units (ICU). Studies carried out in Latin America reveal a higher incidence of candidemia and higher mortality rates when compared to North America or Europe. This highlights the need to develop guidelines for correctly diagnosing and treating candidemia in critically ill patients in the ICU.

The role of the CXCL12/CXCR4 axis in the immunotherapy of non-small cell lung cancer.

Introduction: Peripheral blood mononuclear cells (PBMCs) trafficking is regulated by chemokines, which modulate leukocyte migration toward tumors and may collaborate in the efficacy of immunotherapy. In our study, we investigated whether the CXCL12/CXCR4 axis plays a role in the efficacy of immunotherapy in non-small cell lung cancer (NSCLC) by analyzing CXCR4 expression for CXCR4 in peripheral blood (PB), and the expression of its ligand CXCL12 in tumor.

Methods: We identified PBMCs expressing CXCR4 using flow cytometry in a prospective cohort of NSCLC patients before starting anti-PD-1 immunotherapy.

Visceral fat as the main tomographic risk factor for COVID-19 mortality.

Background: Obesity is a risk factor for COVID-19 mortality; a BMI >35 increases the risk of death up to 12-fold; two previous studies have examined the association between visceral fat quantified by tomography and the risk of severe COVID-19, but not its association with mortality.

Objective: Examine whether tomographic findings differentiated data from patients who died of COVID-19 pneumonia from those who survived in a cohort of patients at a tertiary hospital.

Methods: This was a case-control study (1:1) in which we recruited data from patients at a tertiary care hospital in Mexico.
