Article Abstract
Objective: The aim was to investigate the validity and reliability of the Turkish version of the Modified Medical Research Council (mMRC) Dyspnea Scale in Systemic Sclerosis (SSc) patients with Interstitial Lung Disease.
Material And Methods: Thirty patients diagnosed with SSc according to the 2013 EULAR/ACR criteria were included. After recording the demographic data of the patients, dyspnea was evaluated with the Visual Analogue Scale (VAS), exercise capacity with the 6 Minute Walk Distance (6MWD), fatigue level with the Fatigue Severity Scale (FSS), disease activity with the Medsger Disease Severity Scale, skin involvement with the Modified Rodnan Skin Score, and dyspnea level with the mMRC Dyspnea Scale. The mMRC Dyspnea Scale was administered to the patients with SSc who did not receive any treatment for test-retest reliability at 1-week intervals.
Results: The observed scale range in mMRC (TR) was 0-4, and twelve out of the thirty patients (40%) were classified as having "moderate dyspnea." mMRC (TR) showed a significant moderate positive correlation with VAS dyspnea (rho: 0.718), a low negative correlation with 6MWD (rho: -0.445), and a low positive correlation with FSS (rho: 0.385). The weighted kappa statistic, used as an agreement scale for ordinal responses, was found to be 0.587 (indicating moderate agreement).
Conclusion: The Turkish version of the mMRC Dyspnea Scale demonstrates validity and reliability in SSc patients with interstitial lung disease.

To evaluate a simplified version of the Clinical Frailty Scale (SCFS) among older adults presenting to the emergency department (ED) with acute dyspnea. In this retrospective single-center cohort study, we included patients from the Acute Dyspnea Study (ADYS) cohort. Severity of illness was assessed using the Medical Emergency Triage and Treatment System (METTS).

Objective: To describe the sociodemographic and clinical characteristics of individuals exposed to smoking or biomass smoke and followed at primary health care (PHC) centers across three states in Brazil.
Methods: This was a cross-sectional multicenter study including patients followed at any of four PHC centers in Brazil. Patients ≥ 35 years of age who were smokers or former smokers, or were exposed to biomass smoke were included, the exception being those with physical/mental disabilities and those who were pregnant.
Does quadriceps contractile fatigue influence rehabilitation outcomes in COPD-chronic respiratory failure patients?

Respiratory Rehabilitation Unit, Istituti Clinici Scientifici Maugeri IRCCS, Institute of Lumezzane, Brescia, Italy.
Background: In patients with moderate COPD, response to pulmonary rehabilitation including exercise training varies according to the presence of peripheral muscle fatigue (pMF) of quadriceps. This study investigates the role of pMF in predicting pulmonary rehabilitation outcomes in more severe COPD patients who have already developed chronic respiratory failure (COPD-CRF).
Methods: A analysis of a prospective randomised controlled trial was performed at Istituti Clinici Scientifici Maugeri Lumezzane (Brescia, Italy), involving 30 COPD-CRF patients undergoing a pulmonary rehabilitation programme comprising 20 endurance training sessions.

Division of Pulmonary, Allergy and Critical Care Medicine, Department of Internal Medicine, Konkuk University Hospital, School of Medicine, Konkuk University, Seoul, Korea.
Background: Chronic obstructive pulmonary disease (COPD) is a heterogeneous lung disease characterized by persistent airflow limitation and is a leading cause of mortality worldwide. Pre-COPD refers to a pre-disease state associated with an increased risk of COPD development. This study aims to evaluate the clinical characteristics of individuals with COPD, pre-COPD, and smokers with normal lung function in South Korea, and to provide an updated analysis of the KOCOSS cohort data.

Introduction: Taxanes, including paclitaxel, docetaxel, and cabazitaxel, are widely used anticancer agents that disrupt cell division by binding to microtubules, but are associated with significant adverse reactions, particularly infusion-related reactions (IRRs), such as flushing, urticaria, and respiratory symptoms. Despite premedication with steroids, antihistamines, and antiemetics per guidelines, taxane-induced side effects remain prevalent and can result in treatment delays or discontinuation, impacting patient outcomes. This study aimed to observe and document the incidence and spectrum of adverse reactions to taxanes among premedicated cancer patients to improve management and overall chemotherapy success.
