Potential biomarkers for fatal outcome prognosis in a cohort of hospitalized COVID-19 patients with pre-existing comorbidities.

The difficulty in predicting fatal outcomes in patients with coronavirus disease 2019 (COVID-19) impacts the general morbidity and mortality due to severe acute respiratory syndrome-coronavirus 2 infection, as it wears out the hospital services that care for these patients. Unfortunately, in several of the candidates for prognostic biomarkers proposed, the predictive power is compromised when patients have pre-existing comorbidities. A cohort of 147 patients hospitalized for severe COVID-19 was included in a descriptive, observational, single-center, and prospective study.

Differences in mortality rate among patients hospitalized with severe COVID-19 according to their body mass index.

Background: Obesity has been described as a risk factor for COVID-19 severity and mortality. Previous studies report a linear association between BMI and adverse outcomes, meanwhile in other critical illness, excessive fat tissue is related to improved survival. Whether different BMI is related with the survival of patients with severe COVID-19 deserves further analysis.

Increased expression of hypoxia-induced factor 1α mRNA and its related genes in myeloid blood cells from critically ill COVID-19 patients.

Background: COVID-19 counts 46 million people infected and killed more than 1.2 million. Hypoxaemia is one of the main clinical manifestations, especially in severe cases.

Sacroilitis paraneoplásica: presentación inusual de leucemia linfoblástica aguda.

La sacroilitis es una manifestación poco común de neoplasias hematológicas. Reportamos el caso de una mujer de 40 años que presentó un cuadro de 1 mes de evolución con fiebre y sacroilitis simulando espondiloartritis, acompañado de anemia, hepatomegalia y elevación de marcadores inflamatorios. El abordaje descartó infecciones y causas inflamatorias de dolor sacroilíaco.

A Shift Towards an Immature Myeloid Profile in Peripheral Blood of Critically Ill COVID-19 Patients.

Background: SARS-CoV-2, the etiological agent causing COVID-19, has infected more than 27 million people with over 894000 deaths worldwide since its emergence in December 2019. Factors for severe diseases, such as diabetes, hypertension, and obesity have been identified however, the precise pathogenesis is poorly understood. To understand its pathophysiology and to develop effective therapeutic strategies, it is essential to define the prevailing immune cellular subsets.

[Prone position in non-intubated patient with COVID-19 as a maneuver to avoid intubation].

Background: The COVID-19 (from Coronavirus Disease 2019) is a disease that has generated a pandemic that has affected the world, Mexico included. The spectrum of the disease ranges from asymptomatic infection to severe acute respiratory distress syndrome (ARDS). The objective of the case is to demonstrate the usefulness of the prone position in non-intubated patients.

Association of neutrophil-to-lymphocyte and lymphocyte-to-C-reactive protein ratios with COVID-19-related mortality.

Introduction: Neutrophil-to-lymphocyte (NLR) and lymphocyte-to-C-reactive protein (LCR) ratios are used to predict severity and mortality in various infections.

Objective: To establish the best NLR and LCR cutoff point to predict mortality in patients hospitalized for COVID-19 in Mexico.

Method: Analytical cross-sectional study of patients hospitalized for severe COVID-19 in a specialty hospital.

Adjuvant induced autoimmune/inflammatory syndrome presenting as joint and lung manifestations.

A 59 year-old female with a history of injection of an oily material in the buttocks 11 years ago. She developed symmetric aditive polyarthritis as well as superior and inferior airways involvement. There was no evidence of granulomatosis with polyangiitis (Wegener).

[Fulminant non-Hodgkin lymphoma presenting as lactic acidosis and acute liver failure: case report and literature review].

Unlabelled: Hepatic dysfunction caused by malignancy is uncommon and can be the result of primary hepatocellular carcinoma, liver metastasis, secondary malignancies, or a complication of chemotherapeutic agents. Hematological malignancies, as leukemia, non-Hodgkin lymphoma, and Hodgkin lymphoma, typically do not result in hepatic dysfunction and rarely manifest as fulminant liver failure.

Case Presentation: A 43 year-old male was referred with 2-week diarrhea, nausea and vague abdominal discomfort.
