Effectiveness of ICS/LABA and LAMA/LABA in COPD due to biomass.

Background: COPD due to biomass exposure (COPD-B) is highly prevalent in low- and middle-income countries, and there are no clinical trials designed to evaluate the effectiveness of the treatments currently recommended for patients with COPD due to cigarette smoking (COPD-C). The purpose of the study was to compare the efficacy of fluticasone furoate/vilanterol (FF/V) 100/25 μg and umeclidinium/vilanterol (UMEC/VI) 62.5/25 μg on the rate of exacerbations, the time to first exacerbation, on dyspnoea, health-related quality of life (HRQL), forced expiratory volume in 1 s (FEV) and inspiratory capacity (IC) during a period of 6 months in patients with COPD-B and COPD-C, at a third level referral centre in Mexico City.

Association of Smoking with Disease Progression in Persons with Multiple Sclerosis Undergoing Autologous Hematopoietic Cell Transplantation: A Single-Center Experience.

Background: Smoking remains a significant issue that increases the prevalence of multiple sclerosis (MS) and its progression to secondary progressive forms. Objectives: The goal is to identify the relationship between smoking and disease progression in MS patients who have undergone autologous hematopoietic stem cell transplantation (auto-HSCT) at the Centro de Hematología y Medicina Interna, Clínica Ruiz, Puebla, Mexico. Methods: This retrospective study involved MS patients treated with auto-HSCT, followed for 12 months.

Fractional Exhaled Nitric Oxide (FeNO) in Biomass Smoke-Associated Chronic Obstructive Pulmonary Disease.

Unlabelled: Chronic Obstructive Pulmonary Disease (COPD) is a disease characterized by local and systemic inflammation independently of the risk factor; during the exacerbations, such inflammation is accentuated and amplified. A practical inflammatory marker and one with an applicable predictive value in the follow-up has been sought. FeNO has shown an excellent performance in that respect within the context of asthma and has also been studied in tobacco-smoke COPD (COPD-TS).

Association between muscle quality index and pulmonary function in post-COVID-19 subjects.

Background: The SARS-CoV2 pandemic impacted many critically ill patients, causing sequelae, affecting lung function, and involving the musculoskeletal system. We evaluated the association between lung function and muscle quality index in severely ill post-COVID-19 patients.

Methods: A cross-sectional study was conducted on a post-COVID-19 cohort at a third-level center.

Addiction to Tobacco Smoking and Vaping.

The tobacco epidemic has been one of the biggest public health threats, and smoking is one of the world's largest preventable causes of premature death. An estimated 15.4% of all deaths in the world are attributable to tobacco smoking.

Respiratory diseases in Mexico: analysis from the Global Burden of Disease study 2021.

Background: Respiratory diseases (RD) are often analyzed separately rather than collectively, possibly leading to an underestimation of their total burden.

Objective: To analyze the burden of RD in Mexico for population aged 20 or older from 1990 to 2021.

Material And Methods: We present the burden of RD in Mexico based on estimates of the Global Burden of Disease study for mortality and disability-adjusted life years (DALYs), comprising counts, rates per 100,000, as well as age-standardized rates.

Clinical and microbiological characteristics and inflammatory profile during an exacerbation of COPD due to biomass exposure. A comparison with COPD due to tobacco exposure.

Background: Patients with biomass exposure-related COPD (BE-COPD) is a prevalent disease in developing countries and requires a detailed study of its clinical and inflammatory characteristics, specifying interventions that may differ from tobacco exposure-related COPD (TE-COPD). The objective was to describe clinical characteristics, biomarkers of inflammation, T-helper cells, and microbiological agents during a COPD exacerbation in BE-COPD in comparison with TE-COPD.

Methods: A prospective observational study in patients with moderate or severe exacerbation was recruited either in the emergency room or the COPD clinic.

Air quality in Mexico City during the COVID-19 lockdown possibly decreased COPD exacerbations.

The impact of hydration status and fluid distribution on pulmonary function in COPD patients.

Chronic Obstructive Pulmonary Disease (COPD) patients have alterations in body composition. Bioelectrical impedance analysis (BIA) evaluates body composition, hydration status, and fluid distribution. Subjects with fluid disturbances have been found to have lower FEV, respiratory muscle strength, and poor prognosis.
