Vitamin A Positively Correlates with Secretory Immunoglobulin A: A Cross-Sectional Study in Omicron COVID-19 Outpatients.

Respiratory tract infections remain among the leading causes of mortality worldwide. The COVID-19 pandemic has highlighted the importance of mucosal immunity in defending against infectious agents. Vitamin A is known to influence the production of secretory immunoglobulin A (SIgA) predominantly in the gut, where it is a critical component of the first line of defense on mucosal surfaces.

Association of Food Intake Quality with Vitamin D in SARS-CoV-2 Positive Patients from Mexico: A Cross-Sectional Study.

One of the micronutrients that has attracted the most attention in relation to COVID-19 is vitamin D. Although several factors affect its sufficiency; it has been argued that an optimal diet can ensure the intake of micronutrients with effects on immune response. Therefore, in this work we aimed to evaluate the food intake quality of SARS-CoV-2 positive Mexican patients and some of the common factors related to vitamin D deficiency.

Psychocardiology's Contributions to Comprehensive Cardiovascular Care in Cuba.

This paper describes psychocardiology studies conducted from 2002 through 2018 in the Cardiology Department of the Dr Gustavo Aldereguía Lima University General Hospital in Cienfuegos Province, Cuba. Given the strong association between cardiovascular diseases and lifestyle, negative emotions and personality traits, psychology and medicine are equally necessary components of prevention and patient care, indispensable to primary and secondary prevention and to rehabilitation. When its therapeutic principles are appropriately applied, psychology can have a positive impact on the course of the disease and on patients' adaptation to new habits and lifestyles.

[Cognitive training combined with aerobic exercises in multiple sclerosis patients: a pilot study].

Introduction: The scientific evidences associated to the effectiveness of different techniques of cognitive rehabilitation are still contradictory.

Aim: To compare a program of combined training (physical and cognitive) in front of a program of physical training and to observe their effectiveness about the optimization of the cognitive functions in patients with multiple sclerosis (MS).

Patients And Methods: It was carried out an experimental study in 32 patients with MS.

Neural substrates of decision-making.

Introduction: Decision-making is the process of selecting a course of action from among 2 or more alternatives by considering the potential outcomes of selecting each option and estimating its consequences in the short, medium and long term. The prefrontal cortex (PFC) has traditionally been considered the key neural structure in decision-making process. However, new studies support the hypothesis that describes a complex neural network including both cortical and subcortical structures.

[Risk factors for the development of thrombotic complication in patients with lupus erythematosus and lupus nephropatic].

Introduction: Thrombotic events constitute a frequent complication in patients with systemic lupus erythematosus (SLE) and are associated with increased morbidity and mortality of these patients.

Objective: To identify clinical and laboratorial factors associated with the development of arterial or venous thrombosis in patients with SLE and lupus nephritis (LN).

Material And Methods: We reviewed 200 files of patients with SLE and LN to determine if any patients had presented a symptomatic episode of thrombosis confirmed by an image study.

The amount of alcohol consumption negatively impacts short-term mortality in Mexican patients with alcoholic hepatitis.

Objectives: Mexicans have an increased rate of alcohol abuse and alcoholic liver disease. Factors influencing the severity of alcoholic hepatitis (AH) in Mexicans are unknown. The aims of the present study were to identify the prognostic factors of short-term mortality in Mexican patients with AH and to validate the existing prognostic models.
