[Classic presentation of neuromyelitis optica: clinical case and review of the literature].

Background: Neuromyelitis optica (NMO or Devic's syndrome), characterized by acute attacks of optic neuritis and transverse myelitis, is associated with antiaquaporin 4 antibodies (anti-NMO-IgG) and it has a higher prevalence in non-Caucasian populations, where multiple sclerosis is less common.

Clinical Case: 41-year-old man, with no significant personal medical history, presented with clinical symptoms including paresthesias in the right hemibody and homonymous hemianopsia in the left eye. Three weeks later, he developed lumbalgia associated with paresthesias in both lower limbs up to the T7 sensory level, as well as acute urinary retention, followed by paraplegia.

A detailed quantitative analysis of circulating T peripheral and follicular helper lymphocytes in patients with rheumatoid arthritis and systemic lupus erythematosus.

Introduction And Objective: Peripheral and follicular helper T lymphocytes (Tph and Tfh, respectively) have an important role in B cell immune responses and the pathogenesis of rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Although several studies on the number of Tph and Tfh cells in these conditions have been published, different phenotypes have been employed for their analysis. In this study, we assessed the levels and function of Tph and Tfh cells in blood samples from patients with RA and SLE by using an extended immunophenotype.

Increased Incidence of Rhinovirus Pneumonia in Children During the COVID-19 Pandemic in Mexico.

Human rhinovirus (HRV), traditionally recognized as the primary etiological agent of the common cold, has become the second most important viral agent in bronchopulmonary conditions, such as pneumonia and asthma exacerbations. During the COVID-19 pandemic, several viruses exhibited changes in their epidemiological behavior. This study aims to evaluate the clinical and epidemiological characteristics of children with HRV pneumonia before and during the pandemic in Mexico.

Documenting adaptations to an evidence-based intervention in 58 resource-variable pediatric oncology hospitals across implementation phases.

Background: Adaptation of evidence-based interventions (EBIs) often occurs when implemented in new local contexts and settings. It is unclear, however, during which phase of implementation adaptations are most frequently made and how these changes may impact the fidelity, effectiveness, and sustainability of the EBI. Pediatric Early Warning Systems (PEWS) are EBIs for early identification of deterioration in hospitalized children with cancer.

XIII Consenso SIBEN sobre Traslado Neonatal: Establecer protocolos estructurados para el proceso del traslado neonatal podría mejorar los desenlaces.

La centralización de los partos de alto riesgo en los hospitales con el más alto nivel de atención es fundamental para ampliar el margen de seguridad materno-neonatal y mejorar los desenlaces. Por lo tanto, es altamente recomendable trasladar oportunamente a las pacientes gestantes portadoras de embarazos de alto riesgo y/o con amenazas de parto pretérmino a centros de atención terciaria, sin embargo, no siempre es posible anticipar los riesgos antenatalmente, lo cual resulta en la necesidad de trasladar a neonatos en estado crítico. Lamentablemente, la movilización de los recién nacidos compromete aún más su estado de salud, especialmente en los países latinoamericanos.

UPLC-MS/MS method for fluconazole determination in plasma and its application in Mexican patients with candidaemia.

An accurate and fast ultra-high performance liquid chromatography coupled with tandem mass spectrometry analytical method was developed and validated for quantifying fluconazole levels in human plasma according to the US FDA guidelines. A simple protein precipitation by acetonitrile was employed for the sample preparation. The chromatographic separation was carried out using isocratic elution of water (0.

Position paper on perioperative management and surgical risk in the patient with cirrhosis.

Introduction: Management of the patient with cirrhosis of the liver that requires surgical treatment has been relatively unexplored. In Mexico, there is currently no formal stance or expert recommendations to guide clinical decision-making in this context.

Aims: The present position paper reviews the existing evidence on risks, prognoses, precautions, special care, and specific management or procedures for patients with cirrhosis that require surgical interventions or invasive procedures.

External Evaluation of Population Pharmacokinetic Models of Piperacillin in Preterm and Term Patients from Neonatal Intensive Care.

Background And Objectives: Piperacillin/tazobactam is extensively used off-label to treat late-onset neonatal sepsis, but safety and pharmacokinetic data in this population are limited. Additionally, the organic immaturity of the newborns contributes to a high piperacillin pharmacokinetic variability. This affects the clinical efficacy of the antibiotic treatment and increases the probability of developing drug resistance.

SOX9 immunosuppression in primary colorectal cancer tumors with lymph node metastasis.

Introduction And Aims: Colorectal cancer is the most frequent malignant tumor of the digestive system. Its pathogeny is complex and involves the APC/β-catenin sequence. Lymph node metastases are a significant indicator for determining treatment and are a prognostic factor.

Parkinson's disease patients show delayed hemodynamic changes in primary motor cortex in fine motor tasks and decreased resting-state interhemispheric functional connectivity: a functional near-infrared spectroscopy study.

Significance: People with Parkinson's disease (PD) experience changes in fine motor skills, which is viewed as one of the hallmark signs of this disease. Due to its non-invasive nature and portability, functional near-infrared spectroscopy (fNIRS) is a promising tool for assessing changes related to fine motor skills.

Aim: We aim to compare activation patterns in the primary motor cortex using fNIRS, comparing volunteers with PD and sex- and age-matched control participants during a fine motor task and walking.

Development and validation of a predictive model for choledocholithiasis.

Background: Gallstone-related conditions affect a significant portion of the population, with varying prevalence among different ethnic groups. Complications such as pancreatitis and cholangitis are associated with the presence of common bile duct (CBD) stones. Existing guidelines for diagnosing choledocholithiasis lack precision, leading to excessive use of invasive procedures like endoscopic retrograde cholangiopancreatography (ERCP).

Risk factors for hospitalization in Mexican patients with systemic lupus erythematosus.

Introduction: Systemic lupus erythematosus (SLE) is an autoimmune disease that often requires hospitalization. Most hospitalizations are due to infections and/or disease activity, for which several risk factors have been described in non-Mestizo patients.

Objective: To identify risk factors for hospitalization in patients with systemic lupus erythematosus (SLE).

Connecting Clinical Capacity and Intervention Sustainability in Resource-Variable Pediatric Oncology Centers in Latin America.

Clinical capacity for sustainability, or the clinical resources needed to sustain an evidence-based practice, represent proximal determinants that contribute to intervention sustainment. We examine the relationship between clinical capacity for sustainability and sustainment of PEWS, an evidence-based intervention to improve outcomes for pediatric oncology patients in resource-variable hospitals. We conducted a cross-sectional survey among Latin American pediatric oncology centers participating in Proyecto Escala de Valoración de Alerta Temprana (EVAT), an improvement collaborative to implement Pediatric Early Warning Systems (PEWS).
