Intranasal Versus Intravenous Dexamethasone to Treat Hospitalized COVID-19 Patients: A Randomized Multicenter Clinical Trial.

Background: SARS-CoV2 induces flu-like symptoms that can rapidly progress to severe acute lung injury and even death. The virus also invades the central nervous system (CNS), causing neuroinflammation and death from central failure. Intravenous (IV) or oral dexamethasone (DXM) reduced 28 d mortality in patients who required supplemental oxygen compared to those who received conventional care alone.

Gram-negative ESKAPE bacteria bloodstream infections in patients during the COVID-19 pandemic.

Bloodstream infections due to bacteria are a highly consequential nosocomial occurrences and the organisms responsible for them are usually multidrug-resistant. The aims of this study were to describe the incidence of bacteremia caused by Gram-negative ESKAPE bacilli during the COVID-19 pandemic and characterize the clinical and microbiological findings including antimicrobial resistance. A total of 115 Gram-negative ESKAPE isolates were collected from patients with nosocomial bacteremia (18% of the total bacteremias) in a tertiary care center in Mexico City from February 2020 to January 2021.

Changes in lactate dehydrogenase on admission throughout the COVID-19 pandemic and possible impacts on prognostic capability.

The enzyme lactate dehydrogenase (LDH) is a good marker of general hyperinflammation correlated with mortality for COVID-19, and is therefore used in prognosis tools. In a current COVID-19 clinical randomized trial (CRT), the blood level of LDH was selected as an inclusion criterion. However, LDH decreased during the pandemic; hence, the impact of this decrease on the prognostic value of LDH for mortality was evaluated.

Intranasal dexamethasone: a new clinical trial for the control of inflammation and neuroinflammation in COVID-19 patients.

Background: By end December of 2021, COVID-19 has infected around 276 million individuals and caused over 5 million deaths worldwide. Infection results in dysregulated systemic inflammation, multi-organ dysfunction, and critical illness. Cells of the central nervous system are also affected, triggering an uncontrolled neuroinflammatory response.

The Age-AST-D Dimer (AAD) Regression Model Predicts Severe COVID-19 Disease.

Aim: Coronavirus disease (COVID-19) ranges from mild clinical phenotypes to life-threatening conditions like severe acute respiratory syndrome (SARS). It has been suggested that early liver injury in these patients could be a risk factor for poor outcome. We aimed to identify early biochemical predictive factors related to severe disease development with intensive care requirements in patients with COVID-19.

Mucormycosis at a tertiary-care center in Mexico. A 35-year retrospective study of 214 cases.

Background: Mucormycosis is a rare, invasive disease associated with high mortality rates, produced by opportunistic pathogens related to the Mucorales order and characterised by a diverse range of clinical forms; acute rhino-orbital-cerebral and pulmonary symptoms are the most reported ones.

Objectives: To report the experience of mucormycosis observed in a tertiary-care hospital in Mexico for 35 years.

Methods: This was a retrospective, descriptive and observational study on mucormycosis at a tertiary-care hospital in Mexico from January 1985 to December 2019.

Mucormycosis with cutaneous involvement. A retrospective study of 115 cases at a tertiary care hospital in Mexico.

Background/objectives: Cutaneous mucormycosis is an emerging opportunistic mycosis caused by Mucorales. It can be divided into primary caused by trauma and secondary by extension of rhino-cerebral and disseminated cases. The objective is to present a retrospective study of cases of mucormycosis with cutaneous involvement.
