Small airway involvement in severe asthma: how common is it and what are its implications?

Asthma is a prevalent chronic respiratory disease affecting all age groups globally, causing significant morbidity and mortality. Small airway involvement, often undetected by traditional spirometry, has emerged as a critical aspect of asthma pathophysiology, especially in severe cases. This retrospective observational study aimed to assess small airway dysfunction using impulse oscillometry (IOS) in 94 severe asthma patients.

Correlation of Anthropometry With Plasma Atherogenicity Indices in Subjects With Type 2 Diabetes Mellitus.

Introduction Diabetes mellitus is characterized by chronic hyperglycemia due to insulin deficiency, leading to complications in vital organs. Among these, dyslipidemia is common, presenting as low high-density lipoprotein cholesterol (HDL-c), high triglycerides (TG), Apolipoprotein-B (Apo-B), and small dense low-density lipoprotein (sdLDL) predominance, collectively known as diabetic dyslipidemia. To assess the atherogenic risk in individuals with type 2 diabetes, the atherogenic index of plasma (AIP) and atherogenic coefficient (AC) provide valuable insights beyond routine lipid tests.

Introduction Anti-diabetic drugs used for the treatment of type 2 diabetes mellitus (T2DM) have a unique effect on the body weight and fat distribution of a patient. This study aimed to find out the change in percentage body fat and body composition with the addition of sulfonylureas or dipeptidyl peptidase 4 (DPP-4) inhibitors to metformin monotherapy. Methods An observational 12-week follow-up study was conducted with a sample size of 52 patients.

Role of Bilastine in Allergic Rhinitis: A Narrative Review.

Allergic rhinitis (AR) is considered a trivial disease and is often self-treated with over-the-counter drugs and home remedies. However, AR is a contributing risk factor for asthma associated with complications, including chronic cough, eosinophilic esophagitis, and otitis media with effusion. In AR, inflammation is primarily mediated by histamines.

Class switching is differentially regulated in RBC alloimmunization and vaccination.

Background: Studies of human patients have shown that most anti-RBC alloantibodies are IgG1 or IgG3 subclasses, although it is unclear why transfused RBCs preferentially drive these subclasses over others. Though mouse models allow for the mechanistic exploration of class-switching, previous studies of RBC alloimmunization in mice have focused more on the total IgG response than the relative distribution, abundance, or mechanism of IgG subclass generation. Given this major gap, we compared the IgG subclass distribution generated in response to transfused RBCs relative to protein in alum vaccination, and determined the role of STAT6 in their generation.

Transient Elastography of Liver and Serum Hyaluronic Acid Levels In Adult Transfusion Dependent Thalassemia Patients.

Unlabelled: Iron overload occurs as a result of multiple blood transfusions and increased iron absorption in thalassemia patients. Iron deposition in liver results in liver stiffness and fibrosis. Non invasive methods including imaging and serum biomarkers have been introduced for assessment of liver fibrosis.

Role of Ambulatory Glucose Profile in Precision Medicine in Type 2 Diabetes Mellitus.

Unlabelled: Assessment of diabetes with daily blood glucose fluctuations including peaks and nadirs forms the crux of the modern management. Use of glycemic variability (GV) as a parameter to assess these fluctuations is emerging. It is important to determine the hyperglycemic and hypoglycemic episodes which are the culprits for increasing glycemic variation.

Ethambutol toxicity: Expert panel consensus for the primary prevention, diagnosis and management of ethambutol-induced optic neuropathy.

Ethambutol use may lead to permanent vision loss by inducing a dose- and duration-dependent optic neuropathy. This has been of concern to ophthalmologists and physicians both; however, ethambutol continues to be used because of its anti-mycobacterial action with relative systemic safety. Recently, the guidelines of the Revised National Tuberculosis Control Programme of India have been revised to allow for fixed dose and longer duration of ethambutol use; this is likely to result in an increase in vision-threatening adverse effects.
