To examine the acute effect of gliclazide on exercise performance and recovery of muscle strength in healthy participants. We conducted a randomized, double-blind, placebo-controlled crossover clinical trial in 44 strength-trained men. They were allocated to gliclazide modified release (MR) (90mg, 8h before exercise sessions) or placebo, undergo three consecutive sessions of strength exercise (four sets, 80% of one-repetition maximum [1-RM] of bench press and free squat exercise). We evaluated total volume-load (VL) (#repetitions x 80%1-RM), range of motion (ROM), insulin and glucose levels, creatine kinase MM (CK-MM), lactate dehydrogenase (LDH), interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α), hemodynamic parameters, perceived muscle soreness and recovery scores. Gliclazide enhanced strength exercise performance with improvements in total VL (bench press 23.3%, p<0.001; squat 23.2%, p<0.001), and improved muscle recovery 24-48h post-exercise: ROM (shoulder 1.1%, p<0.001; knee 1.6%, p=0.004), CK-MM (-13.2%, p<0.001), LDH (-12.8%, p<0.001), TNF-α (-17.4%, p<0.001), IL-6 (-5.3%, p<0.001), muscle soreness (-17.7%, p<0.001) and recovery scores (32.5%, p=0.001). However, hypoglycemia events were observed in 3 participants in the gliclazide group. In conclusion, Gliclazide MR 90mg, 8h before strength exercise, produced ergogenic effects (exercise performance and muscle recovery), although hypoglycemia was observed in 7% of subjects.

Introduction: Pleural Effusion (PE) results from an imbalance between pleural fluid production and absorption. It may occur due to multiple aetiologies, including heart failure, infections, malignancies, and liver disease. While Light’s criteria remain the gold standard for classification, they misclassify up to 25% of transudates. Additional biochemical markers such as pleural fluid cholesterol, Alkaline Phosphatase (ALP), and D-dimer have shown promise in enhancing diagnostic accuracy. Aim: To compare the diagnostic efficacy of pleural fluid total cholesterol, pleural ALP, and D-dimer levels with Light’s criteria in differentiating exudative from transudative PEs. Materials and Methods: The present hospital-based crosssectional study was conducted jointly in the Departments of Respiratory Medicine and Biochemistry at Adesh Medical College and Hospital, Shahabad (M), Kurukshetra, Haryana, India, from November 2022 to October 2023. A total of 100 adult patients presenting with PE were recruited. Each patient underwent detailed clinical history, physical examination, chest radiography or Computed Tomography (CT) when indicated, and routine laboratory investigations. Pleural fluid samples were analysed for protein, Lactate Dehydrogenase (LDH), cholesterol, ALP, and D-dimer, while corresponding serum levels were also measured. Effusions were classified as transudative or exudative using Light’s criteria. Data were statistically analysed using independent t-test, Chi-square or Fisher’s exact test, binary logistic regression, and Receiver Operating Characteristic (ROC) curve analysis. A p-value &lt;0.05 was considered statistically significant. Results: In the present study, 71% of participants were male, and the mean age was comparable between the exudative and transudative groups. Pleural fluid cholesterol, pleural ALP, pleural/serum ALP ratio, pleural D-dimer, and pleural/serum D-dimer ratio were significantly higher in exudates than in transudates (p &lt;0.001). ROC analysis demonstrated that all parameters had an Area Under the Curve (AUC) of 1.0, with 100% sensitivity and specificity at the identified cut-off values. Logistic regression analysis identified serum ALP as a protective factor and the pleural/serum LDH ratio as an independent predictor of exudative effusion. Conclusion: Pleural fluid cholesterol, ALP, and D-dimer, along with their respective ratios, are highly reliable in differentiating exudative from transudative PEs and may serve as valuable adjuncts to Light’s criteria. These findings warrant validation in larger multicentric studies.

Mitochondrial dynamics play a crucial role in thyroid cancer progression by regulating apoptosis, metabolism, and oxidative stress. Ceritinib, a tyrosine kinase inhibitor, shows potential anticancer effects; however, its impact on mitochondrial function in thyroid cancer remains obscure. Herein, we aim to investigate the impact of ceritinib on the mitochondrial functionality in TPC-1 thyroid carcinoma cells and the underlying mechanism. Cell viability was assessed with the CCK-8 assay, and the cytotoxicity was determined by evaluation of the lactate dehydrogenase (LDH) release assay. Mitochondrial reactive oxygen species (ROS) were detected by MitoSOX Green staining. Enzyme-linked immunosorbent assay (ELISA) was applied for 8-hydroxydeoxyguanosine (8-OHdG) determination. Real-time PCR was employed for mRNA levels assessment, and western blotting was applied for protein levels. The morphology of mitochondria was evaluated by means of Mitotracker Red CMXRos staining. Ceritinib triggered mitochondrial oxidative stress, evidenced by elevated ROS and 8-OHdG levels, while suppressing manganese superoxide dismutase (Mn-SOD) activity. It also impaired mitochondrial respiration, ATP production, and Complex III activity, leading to dysfunction. Notably, ceritinib promoted mitochondrial fragmentation by enhancing dynamin-related protein 1 (Drp1) translocation to mitochondria, reducing l-OPA1 and increasing S-OPA1 levels, without altering mitofusins 1 and 2 (Mfn-1 and -2) expression. Mechanistically, ceritinib activated the Mitochondrial Calcium Uniporter (MCU)/calpain pathway, increasing MCU, calpain1/2, and calpain activity. Inhibition of MCU by RU360 reversed ceritinib-induced Drp1 mitochondrial translocation, fragmentation, and ATP depletion. Our findings reveal that ceritinib disrupts mitochondrial dynamics via the MCU/calpain/Drp1 axis. This study identifies a previously unreported mechanism for ceritinib in thyroid carcinoma, suggesting a novel therapeutic strategy.

To elucidate the relationships among various itch qualities, blood biomarkers, and patient-reported outcome measures (PROMs) in atopic dermatitis (AD), we characterized 10 qualities of itch (QoIs) in adult Japanese patients with AD and examined their associations with blood biomarkers as well as objective and subjective clinical measures. The QoI was assessed by a translated 10-item questionnaire. The relationship among each QoI and blood biomarkers (including interleukin [IL]-31, thymus and activation-regulated chemokine [TARC], and lactate dehydrogenase levels; differential white blood cell counts, including eosinophil, basophil, and neutrophil relative counts; and total immunoglobulin E levels); PROMs, such as visual analog scale and patient-oriented eczema measure; and objective measures, such as eczema area and severity index, was evaluated. Patients with AD frequently suffered from a sensation similar to crawling like ant (crawling) and stinging and burning sensations. Crawling was positively correlated with serum IL-31 levels but not serum TARC level. Stinging and stabbing sensations were positively correlated with serum TARC level but not with serum IL-31 levels. Stinging, stabbing, and burning sensations were correlated with PROMs and eczema area and severity index. Our limitation is that other cytokines, such as IL-4 and IL-13, were not measured. The QoI in Japanese patients with AD could be classified into IL-31-related and TARC-related types. Our findings suggest relationships between crawling and IL-31 and between stinging and stabbing and TARC in Japanese patients with AD.
