Association of Protein Energy Wasting and Oxidative Stress Markers in Peritoneal Dialysis.

Introduction: Protein-energy wasting (PEW) is highly prevalent among patients undergoing peritoneal dialysis (PD), and it has been proposed that oxidative stress (OS) may contribute to its pathogenesis. This study was an attempt to determine the association between the presence of PEW and OS levels in PD patients.

Methods: This analytical cross-sectional study involved 62 clinically stable PD patients aged ≥ 18 years, between September 2017 and July 2018.

Clinical characteristics and severity markers in hospitalized COVID-19 patients from western Mexico: a comparative analysis of Delta and Omicron variants.

Introduction: COVID-19 is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a virus notable for its rapid mutation rate, which has led to the emergence of various variants such as Delta and Omicron, each with potentially different levels of transmissibility and virulence. Therefore, this study aims to compare clinical charactheristics and markers associated with the severity of COVID-19 in hospitalized patients from western Mexico who were infected with the Delta and Omicron variants of SARS-CoV-2.

Methods: This cross-sectional study involved 66 patients hospitalized for COVID-19, diagnosed by RT-qPCR.

[Prevalence of asthma in patients hospitalized for pneumonia associated to SARS-CoV-2 infection].

Background: The association between asthma and COVID-19 remains controversial. Objective. To establish the prevalence of asthma in a sample of patients with COVID-19-associated pneumonia; furthermore, to describe the clinical characteristics of patients with asthma compared to patients without asthma.

Biventricular Takotsubo Cardiomyopathy as an Unusual Presentation of SARS-CoV-2 mRNA Vaccine-Associated Multisystemic Inflammatory Syndrome.

Biventricular takotsubo cardiomyopathy (BiTCM) is a rare entity, seldom reported. We describe a case of a female presenting with multisystemic inflammatory syndrome associated with the administration of a vaccine against coronavirus disease 2019 (COVID-19). In this particular case, the patient experienced the onset of symptoms shortly after receiving a COVID-19 vaccine.

Association Between Allergic Rhinitis and Asthma in Adults With Loss of Interest in Sex.

Background: The alterations of sexual desire in allergy respiratory diseases have seldom been analyzed. This paper aims to evaluate the association of allergic rhinitis and asthma among adults with the loss of interest in sex.

Methods: Through a cross-sectional study, we compared three groups of subjects: one with patients with allergic rhinitis, another with allergic asthma, and a control group.

Autoantibodies in the pathogenesis of idiopathic inflammatory myopathies: Does the endoplasmic reticulum stress response have a role?

Idiopathic inflammatory myopathies (IIMs) are a group of rare, acquired autoimmune diseases characterized by profound muscle weakness and immune cell invasion into non-necrotic muscle. They are related to the presence of antibodies known as myositis-specific antibodies and myositis-associated antibodies, which are associated with various IIM phenotypes and the clinical prognosis. The possibility of the participation of other pathological mechanisms involved in the inflammatory response in IIM has been proposed.

Role of c-miR-21, c-miR-126, Redox Status, and Inflammatory Conditions as Potential Predictors of Vascular Damage in T2DM Patients.

The development of type 2 diabetes mellitus (T2DM) vascular complications (VCs) is associated with oxidative stress and chronic inflammation and can result in endothelial dysfunctions. Circulating microRNAs play an important role in epigenetic regulation of the etiology of T2DM. We studied 30 healthy volunteers, 26 T2DM patients with no complications, and 26 T2DM patients with VCs, to look for new biomarkers indicating a risk of developing VCs in T2DM patients.

Asthma and COVID-19 among healthcare workers from a Mexican Hospital: is there an association?

Background: Asthma does not appear to be a risk factor for developing COVID-19.

Objective: The objective of the study was to analyze the role of asthma as a factor associated with COVID-19 among healthcare workers (HW).

Methods: A crosssectional study was conducted in HW from a Mexican hospital.

Use of mNUTRIC-Score for Nutrition Risk Assessment and Prognosis Prediction in Critically Ill Patients with COVID-19: A Retrospective Observational Study.

Introduction: Nutritional risk is highly prevalent in patients with COVID-19. Relevant data on nutritional assessment in the critically ill population are scarce. This study was conducted to evaluate the modified Nutrition Risk in the Critically Ill (mNUTRIC)-Score as a mortality risk factor in mechanically ventilated patients with COVID-19.

[Prevalence of blood eosinophilia in adults with COPD according to the cut-off point].

Objective: To determine the prevalence of blood eosinophilia in adults with chronic obstructive pulmonary disease (COPD) according to different cut-off points.

Methods: A cross-sectional study was carried out in patients with COPD. The frequency of blood eosinophilia was determined by absolute (cells/ µL) and relative (%) eosinophil count.
