Development of Polyvinyl Alcohol Hydrogels for Controlled Glucose Release in Biomedical Applications.

Polyvinyl alcohol (PVA) hydrogels have a wide range of applications in the pharmaceutical and biomedicine fields due to their exceptional biophysical properties. The study focuses on preparing and characterizing capsule-shaped PVA hydrogels to enhance their biocompatibility and porosity for controlled glucose release and cell proliferation. The hydrogels were prepared using different concentrations (Cs) and molecular weights (MWs) of PVA, with two different lengths, A (10 mm) and B (20 mm), to control glucose release over 60 min.

Use of N-acetylcysteine plus simethicone to improve mucosal visibility in upper digestive endoscopy via systematic alphanumeric-coded endoscopy: a randomized, double-blind controlled trial.

Background: The use of antifoaming and mucolytic agents prior to upper gastrointestinal (GI) endoscopy and a thorough systematic review are essential to optimize lesion detection. This study evaluated the effect of simethicone and N-acetylcysteine on the adequate mucosal visibility (AMV) of the upper GI tract by an innovative systematic method.

Methods: This randomized, double-blind controlled trial included consecutive patients who underwent diagnostic upper GI endoscopy for screening for early neoplasms between August 2019 and December 2019.

The Prevalence of Depression and Anxiety Symptoms and Their Association With Respiratory Diseases.

Introduction: Patients with respiratory diseases face adverse situations such as symptom management, general condition deterioration, and a hostile perception of the hospital environment, favoring the appearance of anxiety and depression.

Methods: A total of 317 patients hospitalized for a disease of pulmonary origin were analyzed and divided into the following subgroups: infectious, oncological, acute, and chronic diseases. Patients over 18 years of age with preserved cognitive capacity were included in the study.

Utility of a clinical risk scale to predict the requirement of advanced airway management in patients with a diagnosis of deep neck abscess.

Objectives: To analyze the clinical utility of a clinical risk scale to predict the need for advanced airway management in patients with deep neck abscess.

Methods: Observational, analytical, cross-sectional study. Patients over 18 years old, both genders, with surgical management of a deep neck abscess, between January 1st, 2015 to December 31th, 2021, who were applied the clinical risk scale (https://7-414-5-19.

Burnout symptoms among physicians and nurses before, during and after COVID-19 care.

Objective: this study evaluated burnout symptoms among physicians and nurses before, during and after COVID-19 care.

Method: a cross-sectional comparative study in the Pulmonary Care unit of a tertiary-level public hospital. The Maslach Burnout Inventory was used.

Tuberculosis extrapulmonar: un problema de salud pública.

Extrapulmonary tuberculosis is defined as that case of tuberculosis clinically diagnosed and confirmed by bacteriological studies that affects tissues and organs outside the lung parenchyma. Mexico is in third place among Latin American countries in terms of the incidence of pulmonary and extrapulmonary tuberculosis. Culture methods are still the gold standard for the diagnosis of extrapulmonary tuberculosis since they identify the species and susceptibility to drugs.

Asociación del signo de Moore con la presencia de absceso profundo de cuello de espacio retrofaríngeo.

Background: Deep neck abscesses can cause life-threatening complications. They are diagnosed by physical examination, and contrasted tomography as the gold standard. There are no studies about the association of Moore's sign with infections of the retropharyngeal space.

Gastric variceal bleeding treated through endoscopic ultrasound-guided coiling and N-butyl-2-cyanoacrylate application.

Objective: To evaluate efficacy and safety between dual angiotherapy (endocoil plus N-butyl-cyanoacrylate) guided by endoscopic ultrasound) versus N-butyl-cyanoacrylate in the secondary prophylaxis of gastroesophageal varices (GOV).

Method: Prospective non-inferiority study comparing two gastric variceal eradication techniques. We evaluated technical and clinical success, GOV occlusion and eradication, rebleeding, reoperation, GOV-free period, complications, and mortality.

Usefulness of optical enhancement endoscopy combined with magnification to improve detection of intestinal metaplasia in the stomach.

 The light blue crest observed in narrow band imaging endoscopy has high diagnostic accuracy for diagnosis of gastric intestinal metaplasia (GIM). The objective of this prospective study was to evaluate the diagnostic accuracy of magnifying i-scan optical enhancement (OE) imaging for diagnosing the LBC sign in patients with different levels of risk for gastric cancer in a Mexican clinical practice.  Patients with a history of peptic ulcer and symptoms of dyspepsia or gastroesophageal reflux disease were enrolled.

Characteristics and mortality of Mexican patients with COVID-19 and mechanical ventilation.

Interleukin 8 Is Overexpressed in Acute Rejection in Kidney Transplant Patients.

The main complication associated with renal graft loss is immune rejection. The gold standard for the diagnosis of renal graft rejection is percutaneous renal biopsy, which is expensive and can lead to complications. Inflammation is one of the main pathogenic pathways in allograft rejection, and urine samples seem to be efficient windows to explore the allograft condition with a high cost-benefit ratio.
