The patient remained asymptomatic throughout the clinical course. Comprehensive evaluations-including thyroid function tests, biochemical profiling, cervical magnetic resonance imaging, electronic laryngoscopy, radionuclide scanning, and portable sleep monitoring-confirmed the presence of a lingual thyroid with subclinical hypothyroidism. Imaging demonstrated the ectopic tissue at the tongue base to be the sole functioning thyroid gland. Levothyroxine therapy was initiated, resulting in normalization of thyroid hormone levels. Polysomnography was performed due to the anatomical location of the lesion and excluded obstructive sleep apnea or ventilatory compromise. Given the patient's strong motivation to resume flight duties, a multidisciplinary aeromedical evaluation was conducted. Based on clinical stability, absence of symptoms, and treatment response, the pilot was deemed aeromedically fit.

This case suggests that congenital endocrine anomalies may be compatible with high-demand occupational roles in select cases, pending comprehensive individual evaluation and risk-based aeromedical assessment.

There were two groups: group 1 included 49 newly diagnosed, drug-naive prediabetic patients, and group 2 consisted of 29 newly diagnosed, drug-naive,T2DM patients. Written informed consent was obtained from all participants. This study was approved by the Medical Ethics Committee of Damascus University (No. m/471 -12/5/2021) and registered with the Australian New Zealand Clinical Trials Registry (Trial ID: ACTRN12624001135505). Inclusion criteria included newly diagnosed prediabetic or T2DM subjects who had received no treatment, based on the 2015 American Diabetes Association criteria. Exclusion criteria entailed past histories of severe cardiovascular, renal, tumor, or autoimmune diseases and use of drug therapies including oral hypoglycemic agents. General and demographic information (Sex, age, BMI) was obtained, and blood samples were taken after fasting for 12 h. Fasting plasma glucose (FPG) levels were measured using an automatic analyzer (AMS, Italy). HbA1c levels were measured photometrically using the HemoCue (HbA1c 501 analyzer,America).Insulin levels were determined via an ELISA kit (Diametra, Italy), and soluble death receptors (TNFR1, Fas, TRAIL-R2) were measured using ELISA kits (Raybiotech, USA). The following formula calculates Homeostatic Model Assessment of Beta Cell Function( HOMA-B), HOMA-B (%) = [360 × basal insulin (µIU/mL)] / [basal glucose (mg/dL) - 63]. Statistical analyses were carried out in SPSS version 25. Distribution of the data was carried out using the Kolmogorov-Smirnov test for normality. Student t test for independent samples were done for normally distributed data, while Mann-Whitney U test was used for nonnormal variables.

Furthermore, we assess the efficacy of the TyG index in forecasting occurrences of atypical blood glucose metabolism within this particular demographic.</p><p><strong>Methods: </strong>This cross-sectional study utilized data collected from adults who underwent a health assessment at our institution between December 2022 and September 2024. The evaluation of insulin sensitivity was conducted utilizing the TyG index, whereas muscle mass was quantified through bioelectrical impedance analysis (BIA). Logistic regression, Receiver Operating Characteristic (ROC) curve analysis, subgroup analysis, and interaction effect analysis were employed to evaluate the association between triglyceride-glucose index levels with subgroups based on different body masses.</p><p><strong>Results: </strong>This study comprised 1278 people with diminished muscle mass. We found a positive association between TyG index (OR = 7.73; 95% CI: 4.62-13.51; P < 0.001) and the risk of abnormal glucose metabolism among those who were overweight/obese. The analysis of the ROC curve revealed that the TyG index possesses a significant predictive capability for identifying abnormal glucose metabolism in individuals exhibiting diminished muscle mass (AUC = 0.906). This predictive value is particularly pronounced in those who do not present with overweight or obesity (AUC = 0.915), in contrast to its effectiveness in individuals who have both reduced muscle mass and overweight or obesity. Subgroup analyses confirmed the positive association of TyG index with abnormal blood glucose incidence.</p><p><strong>Conclusion: </strong>This study assessed the link between TyG and abnormal blood glucose metabolism events risk in people with sarcopenia and compared its predictive power for abnormal blood glucose metabolism events onset in those with low muscle mass but not overweight or obese. We recommend using the TyG index as the best predictive marker for assessing abnormal blood glucose metabolism events risk in individuals without concurrent overweight or obesity, regardless of their body mass index.</p>","PeriodicalId":9152,"journal":{"name":"BMC Endocrine Disorders","volume":"25 1","pages":"212"},"PeriodicalIF":3.3,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12482197/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
