The ∆Pv-aCO2/∆Ca-vO2 ratio as a predictor of mortality in patients with severe acute respiratory distress syndrome related to COVID-19.

Objective: To evaluate the central venous-to-arterial carbon dioxide difference combined with arterial-to-venous oxygen content difference (∆Pv-aCO2/∆Ca-vO2 ratio) as a predictor of mortality in patients with COVID-19-related severe acute respiratory distress syndrome (ARDS).

Methods: Patients admitted to the intensive care unit with severe ARDS secondary to SARS-CoV-2, and invasive mechanical ventilation were included in this single-center and retrospective cohort study performed between April 18, 2020, and January 18, 2022. The tissue perfusion indexes (lactate, central venous oxygen saturation [ScvO2], and venous-to-arterial carbon dioxide pressure difference [∆Pv-aCO2]), anaerobic metabolism index (∆Pv-aCO2/∆Ca-vO2 ratio), and severity index (Simplified Acute Physiology Score II [SAPSII]) were evaluated to determine its association with the mortality through Cox regression analysis, Kaplan-Meier curve and receiver operating characteristic (ROC) curve.

[Factors associated with functionality in patients with closed ankle fracture].

Background: Ankle fractures are among the most frequent fractures in the lower limb, predominantly affecting young people and representing approximately 9% of all fractures.

Objective: To identify the factors associated with functionality in patients with closed ankle fracture.

Material And Methods: Observational and retrospective study.

[Maternal-fetal outcomes in women with gestational diabetes in an intensive control program].

Background: Gestational diabetes mellitus (GDM) is first diagnosed during pregnancy and it is the most frequent maternal hyperglycemia.

Objective: To know fetal and maternal outcomes in an intensive control program in pregnant women with and without DMG at the Instituto Mexicano del Seguro Social (Mexican Institute for Social Security) Regional General Hospital No. 6, in Ciudad Madero, Tamaulipas.

[Effect of rehabilitation on functionality/quality of life in stroke due to COVID-19].

Background: COVID-19 can present neurological complications of the central nervous system. Ischemic-type strokes have been reported in this population. Neurological rehabilitation participates in the functional recovery and improvement of the quality of life of these patients.

Simplified acute physiology score II and Mannheim peritonitis index are associated with in-hospital mortality in patients with abdominal sepsis admitted to ICU.

Objective: The objective of this study was to assess the association and interaction of laboratory parameters, Simplified Acute Physiology Score II (SAPSII), Modified Shock Index (MSI), and Mannheim Peritonitis Index (MPI) with in-hospital mortality.

Material And Methods: We conducted a single-center case-control study. Adult patients with abdominal sepsis were included from May 2015 to May 2020.

Características clínico-demográficas de pacientes recuperados de COVID-19 en una unidad de rehabilitación de tercer nivel.

Objective: To determine the clinical-demographic characteristics of patients recovered from COVID-19 in a third level rehabilitation service.

Method: A cross-sectional and descriptive study of recovered COVID-19 patients in a rehabilitation service was carried out. Demographic, personal pathological history, his work activity and COVID-19 were taken, as well as alterations after the disease.

Reply to: Effect of prone positioning without mechanical ventilation in COVID-19 patients with acute respiratory failure.

[Physical activity, biochemical and somatometric profile's residents physicians during the COVID-19 pandemic].

Background: During the COVID-19 containment, a decrease in physical activity, vigorous physical exercise and an increase in sedentary lifestyle were documented.

Objective: To describe the physical activity, biochemical and somatometric profile of Rehabilitación resident physicians during the COVID-19 pandemic and to determine the correlations between these variables.

Material And Methods: A cross-sectional, analytical study of medical residents was carried out.

[Cardiorespiratory and neuromusculoskeletal symptoms with post-acute COVID-19 in a Rehabilitation center].

Background: COVID-19 predominantly affects the respiratory system. However, persistent extrapulmonary (musculoskeletal and cardiovascular) conditions have been reported.

Objective: To determine the most frequent cardiorespiratory and neuromusculoskeletal symptoms in patients with post-acute COVID 19 in a rehabilitation center.

[Childhood obesity: a risk factor for development of flatfoot].

Background: In Mexico, the prevalence of overweight and obesity is 34.4% in school-age children (ENSANUT 2012), which may induce a vicious cycle of flatfoot-plantalgia-sedentarism-obesity, although the presence and degree of flatfoot in school-age children with obesity has not yet been described in a Mexican population. The objective of the study was to determine the prevalence of flatfoot and its association with obesity in school-age children living in Tampico.

Microsporidia infection in a mexican kidney transplant recipient.

Microorganisms of the microsporidia group are obligated intracellular protozoa that belong to the phylum Microspora; currently they are considered to be related or belong to the fungi reign. It is considered an opportunistic infection in humans, and 14 species belonging to 8 different genera have been described. Immunocompromized patients such as those infected with human immunodeficiency virus (HIV), also HIV serum-negative asymptomatic patients, with poor hygienic conditions, and recipients of bone marrow or solid organ transplantation are susceptible to develop deinfection.
