Promoter methylation status of , and in peripheral blood leukocytes in adolescents with obesity-related asthma.

A higher Th17-immune response characterises obesity and obesity-related asthma phenotype. Nevertheless, obesity-related asthma has a more significant Th17-immune response than obesity alone. Retinoid-related orphan receptor C (RORC) is the essential transcription factor for Th17 polarisation.

Retinol-binding protein 4 and plasminogen activator inhibitor-1 as potential prognostic biomarkers of non-allergic asthma caused by obesity in adolescents.

Background: Non-allergic asthma caused by obesity is a complication of the low-grade chronic inflammation inherent in obesity. Consequently, the serum concentrations of adipokines such as retinol-binding protein 4 (RBP4) and plasminogen activator inhibitor-1 (PAI-1) increase. No gold standard molecule for the prediction of non-allergic asthma among obese patients has been identified.

Associations of TNFA, IL17A, and RORC mRNA expression levels in peripheral blood leukocytes with obesity-related asthma in adolescents.

Obesity is associated with a unique non-T2 asthma phenotype, characterised by a Th17 immune response. Retinoid-related orphan receptor C (RORC) is the master transcription factor for Th17 polarisation. We investigated the association of TNFA, IL17A, and RORC mRNA expression levels with the non-T2 phenotype.

Measles outbreak during the COVID-19 pandemic in Mexico.

Measles is an exanthematous disease caused by a virus of the Morbillivirus genus. On February 23, 2020, the exanthema began in the first confirmed case of measles this year. At the same time, on February 28, 2020, the first case of the new coronavirus disease (COVID-19) was confirmed.

IL-17A and TNF-α as potential biomarkers for acute respiratory distress syndrome and mortality in patients with obesity and COVID-19.

Coronavirus disease 2019 (COVID-19) was declared a pandemic and international health emergency by the World Health Organization. Patients with obesity with COVID-19 are 7 times more likely to need invasive mechanical ventilation than are patients without obesity (OR 7.36; 95% CI: 1.

Safety and efficacy of step-down to oral outpatient treatment versus inpatient antimicrobial treatment in pediatric cancer patients with febrile neutropenia: A noninferiority multicenter randomized clinical trial.

Background: It has been suggested that low-risk febrile neutropenia (FN) episodes can be treated in a step-down manner in the outpatient setting. This recommendation has been limited to implementation in middle-income countries due to concerns about infrastructure and lack of trained personnel. We aimed to determine whether early step-down to oral antimicrobial outpatient treatment is not inferior in safety and efficacy to inpatient intravenous treatment in children with low-risk FN.

Serological and molecular study of Hepatitis E virus in pediatric patients in Mexico.

Introduction And Objectives: Cases of viral hepatitis reported in Mexico are typically identified as hepatitis A, B and C. However, unspecified cases are reported annually. Hepatitis E virus (HEV) is an emergent agent that causes a self-limiting infection that can evolve to chronic in immunosuppressed individuals.

Decreased methylation profiles in the TNFA gene promoters in type 1 macrophages and in the IL17A and RORC gene promoters in Th17 lymphocytes have a causal association with non-atopic asthma caused by obesity: A hypothesis.

Obesity is a serious public health problem worldwide and has been associated in epidemiological studies with a unique type of non-atopic asthma, although the causal association of asthma and obesity has certain criteria, such as the strength of association, consistency, specificity, temporality, biological gradient, coherence, analogy and experimentation; nevertheless, the biological plausibility of this association remains uncertain. Various mechanisms have been postulated, such as immunological, hormonal, mechanical, environmental, genetic and epigenetic mechanisms. Our hypothesis favours immunological mechanisms because some cytokines, such as tumour necrosis factor alpha (TNF-α) and interleukin (IL)-17A, are responsible for orchestrating low-grade systemic inflammation associated with obesity; however, these cytokines are regulated by epigenetic mechanisms, such as gene promoter methylation.

Clinical Significance of Fractional Anisotropy Measured in Peritumoral Edema as a Biomarker of Overall Survival in Glioblastoma: Evidence Using Correspondence Analysis.

Introduction: Fractional anisotropy (FA), a diffusion tensor image (DTI) derived biomarker is related to invasion, infiltration, and extension of glioblastoma (GB). We aimed to evaluate FA values and their association with intervals of overall survival (OS).

Materials And Methods: Retrospective study conducted in 36 patients with GB included 23 (63.

PIPERACILLIN/TAZOBACTAM IN CONTINUOUS INFUSION VERSUS INTERMITTENT INFUSION IN CHILDREN WITH FEBRILE NEUTROPENIA.

Background: Febrile neutropenia (FN) is a common complication in children who receive chemotherapy for cancer.

Objective: The objective of this study was to evaluate the clinical efficacy of the continuous versus intermittent infusion of piperacillin/tazobactam (TZP) in febrile neutropenic pediatric patients.

Methods: This is a non-blinded randomized controlled clinical trial.

[Priority actions towards a national program for detection, treatment, and monitoring of patients with hepatitis C.].

In the Mexican health scenario, the hepatitis C virus epidemic is present, along with its comorbidities and premature mortality. Acting immediately will allow its containment in short term with the proper implementation of the current available tools for prevention, diagnosis and highly effective pharmacological therapies. The Coalition for the study of hepatitis C in Mexico has developed a position paper that takes advantage of these containment measures and presents the development of a National program for the detection, timely treatment and follow-up of patients with hepatitis C.

[The horizon of medical attention in pediatrics: what to do in the case of children who are in abandonment, conflict, harm or danger situations in combination with a severe disease?].

Background: Laws refer that minors do not have the capability to give informed consent for their own medical attention. However, there are special conditions in which they are allowed to decide about their health. The greater the judgement and experience limitations in minors, the less weight is given to the values and objectives they express.

Potential drug-drug interactions and their risk factors in pediatric patients admitted to the emergency department of a tertiary care hospital in Mexico.

Background: Drug-drug interactions (DDIs) detected in a patient may not be clinically apparent (potential DDIs), and when they occur, they produce adverse drug reactions (ADRs), toxicity or loss of treatment efficacy. In pediatrics, there are only few publications assessing potential DDIs and their risk factors. There are no studies in children admitted to emergency departments (ED).

Serological Evidence of Borrelia Burgdorferi Infection in Mexican Patients with Facial Palsy.

Background: Facial palsy is the most frequent manifestation of neuroborreliosis in the United States, Europe, and Asia, whereas in Mexico, its frequency is unknown.

Objective: We aimed to determine the frequency of Borrelia spp. infection in patients with acute facial palsy in Mexico.

Self-perception and knowledge of evidence based medicine by physicians.

Background: The influence, legitimacy and application of Evidence Based Medicine (EBM) in the world is growing as a tool that integrates, the best available evidence to decision making in patient care. Our goal was to identify the relationship between self-perception about the relevance of Evidence Based Medicine (EBM) and the degree of basic knowledge of this discipline in a group of physicians.

Methods: A survey was carried out in a third level public hospital in Mexico City.

[Curriculum analysis and comparison between strategies or programs for early child development in Mexico].

Background: Most of the strategies or programs that support early child development in Mexico are independent efforts that vary in scale, services offered and means of providing them. For the evaluation of the quality of these programs, an important aspect is the curriculum content. The aim of this study was to analyze and compare the curriculum content of the different strategies or programs focused on the promotion and intervention of early child development, which are offered by the Federal Government in Health and Education sectors in Mexico.

A comprehensive intervention for adverse drug reactions identification and reporting in a Pediatric Emergency Department.

Background: Physicians identify from 45.7 to 96.2 % of Adverse Drug Reactions (ADRs) in their patients, with under-reporting ranging from 6 to 100 %.

A social health services model to promote active ageing in Mexico: design and evaluation of a pilot programme.

The objective of the study was to design and evaluate a pilot programme aimed at promoting the active ageing of older adults at the Mexican Institute of Social Security. The study was conducted in three stages: (a) design; (b) implementation; and (c) before-after evaluation through analysis of changes in functional status, occupational functioning and health-related quality of life. To overcome the limitations of the study design, we evaluated the effect of 80 per cent adherence to the programme on the outcome variables using the generalised linear regression models (GLM).

Direct medical costs of neonatal respiratory distress syndrome in two specialized public hospitals in Mexico.

Objective: To estimate direct medical costs (DMC) associated with treatment of Respiratory Distress Syndrome (RDS) in newborns (NB) in two specialized public hospitals in Mexico.

Materials And Methods: The perspective used was health care payer. We estimated DMC associated with RDS management.

[Review of models for the analysis of ethical dilemmas].

In pediatric medical practice it is common to encounter situations that represent a dilemma for health professionals. A dilemma occurs when ethical problems found in professional practice cause serious internal conflicts because they imply actions that contradict their colleagues, employees, or their own personal values and are classified as personal value conflicts, conflicts with other professionals, conflicts with clients and with organizations. A literature review allowed identifying different models to debate these types of dilemmas.
