Purpose Of Review: This review summarizes recent basic, translational, and clinical research on type 2 diabetes (T2D) and its relationship with asthma severity in the context of T2D mechanisms and asthma outcomes.
Recent Findings: Several clinical asthma outcomes, such as lung function and exacerbations, demonstrate a strong association between T2D and asthma and support that T2D contributes to worse asthma outcomes. Multiple mechanisms underlying those observed associations, and their representative biomarkers, have been proposed. However, prospective, controlled human studies in the context of both T2D and asthma are limited.
Summary: T2D is associated with worse asthma outcomes and more severe asthma. Yet patients with more severe or uncontrolled asthma are also at a higher risk for systemic steroid exposure, which worsens glycemic control and metabolic dysregulation. Preclinical and translational studies point to metabolic dysregulation as a driver of airway inflammation. Addressing these metabolic pathways through T2D treatment may, in turn, directly or indirectly improve clinical asthma outcomes. While additional research is needed to identify biomarkers of risk and treatment response in metabolic asthma, this review highlights the importance of considering T2D as a clinically relevant asthma comorbidity.

Association between oxidative balance score and all-cause, CVD and respiratory-related mortality in the US older adults of asthma patients with diabetes.
Front Nutr
January 2025
School of Medicine, Nankai University, Tianjin, China.
Background: This study aims to investigate the correlation between oxidative balance score (OBS) and all-cause, cardiovascular disease (CVD) and respiratory-related mortality within a cohort that includes older asthma patients with diabetes.
Methods: Data from the National Health and Nutrition Examination Survey (NHANES) spanning from 2001 to 2018, which included 611 participants, were analyzed. Mortality outcomes were determined by linking the data to National Death Index (NDI) records through December 31, 2019.
Cannabis consumption and risk of asthma: a systematic review and meta-analysis.
BMC Pulm Med
January 2025
Global Health and Infectious Diseases Control Institute, Nasarawa State University, Keffi, Nigeria.
Background: Cannabis is the third most widely used psychoactive substance globally, and its consumption has been increasing, particularly with the growing trend of legalization for medicinal and recreational use. Recent studies have raised concerns about the potential impact of cannabis on respiratory health, specifically the risk of asthma, a significant public health concern. This systematic review aimed to consolidate research on the association between cannabis use and the risk of asthma.

Department of Respiratory Medicine, The Second Hospital of Jilin University, No. 4026 Yatai street, Changchun, 130041, Jilin, China.
Background: Ectopic thyroid tissue (ETT) is a rare congenital anomaly caused by the abnormal embryonic migration of thyroid tissue, leading to its presence outside its usual pretracheal location. This condition can lead to diagnostic challenges, especially when located within the airway, as it mimics other respiratory disorders such as asthma.
Case Presentation: We report the case of a 69-year-old man with endotracheal ETT presenting with severe dyspnea, and the lesion was initially suspected to be malignant.
Clinical effectiveness and implementation outcomes of pMDI-to-DPI switch in children between 5 and 12 years of age: a scoping review protocol.

Introduction: Inhalers are critical in asthma treatment, and inappropriate inhaler use leads to poor asthma outcomes. In adults and adolescents, dry powder inhalers (DPIs) are safe and effective alternatives to mainstay pressurised metered dose inhalers and could bridge the asthma care gap while also reducing the environmental burden of asthma care. Despite being licensed for use in ages 5 years old and older, the evidence for clinical effectiveness is less clear for patients between ages 5 and 12 years.

Background: The 2006 National Institute of Allergy and Infectious Disease/Food Allergy and Anaphylaxis Network (NIAID/FAAN) anaphylaxis criteria are widely used in clinical care and research. In 2020, the World Allergy Organization (WAO) published modified criteria that have not been uniformly adopted. Different criteria contribute to inconsistent care and research outcomes.
