Studies have shown that the co-occurrence of diabetes mellitus (DM) and thyroid dysfunction (TD) exacerbates diabetes complications and imposes a financial burden on the healthcare system. Therefore, this study aimed to investigate the prevalence of TD-DM comorbidity and its associated risk factors. This cross-sectional study was conducted on enrollment phase data of the TABARI cohort population which consisted of 10,255 adults aged between 35 to 70 years old residing in Sari, Mazandaran, Iran from 2015 to 2017. A total of 9939 out of 10,255 individuals (96.92%) entered the study. The prevalence of TD among T2DM patients was 13.2%. The prevalence of T2DM among patients with TD was 9.2%. Furthermore, the prevalence of TD-DM comorbidity in the overall population was 2.2%. Logistic regression analysis revealed that the odds of TD-DM comorbidity was significantly higher in women (OR 2.85; 95% CI 1.58-5.11), in the age group of 60-70 years (OR 9.62; 95% CI 3.69-25.10), in smokers (OR 2.32; 95% CI 1.19-4.52), in individuals with high waist circumference (WC) (OR 2.22; 95% CI 1.32-3.75), in individuals with low high-density lipoprotein (HDL) (OR 1.60; 95% CI 1.20-2.14), in individuals with high total cholesterol (TC) (OR 1.71; 95% CI 1.21-2.41), in individuals with high triglycerides (TG) (OR 1.79; 95% CI 1.27-2.51), and significantly lower in individuals with higher physical activity (PA) (OR 0.67; 95% CI 0.49-0.93). The present study demonstrated a prevalence of 2.2% in patients with both TD and T2DM. Additionally, female gender, older age, smoking, high WC, low HDL, high TC, high TG, and low PA were predictors of TD-DM comorbidity.

UNASSIGNED: This review aims to discuss the psychological aspects of Graves\' ophthalmopathy (GO), estimate the prevalence of depression and anxiety disorders in GO, examine whether these psychiatric disorders are more prevalent in GO than in Graves\' disease (GD) without eye disease, and evaluate the main contributors for depression and anxiety in GO.
UNASSIGNED: A review of the literature.
UNASSIGNED: Both depression and anxiety are associated with GO. The prevalence of depression and anxiety disorders specifically in GO patients was estimated at 18-33% and 26-41%, respectively. The reported prevalence in GD patients ranged from 9% to 70% for depression and from 18% to 88% for anxiety disorders. Significantly higher levels of depression and anxiety were found in GD patients compared with patients with non-autoimmune hyperthyroidism. Conflicting results have been reported regarding the association of antithyroid autoantibodies with depression and anxiety disorders. Serum thyroid hormone levels do not correlate with the severity of depression and anxiety. An improvement of psychiatric symptoms is observed in hyperthyroid patients after treatment of thyrotoxicosis. Moreover, depression and anxiety are significantly related to impaired quality of life (QoL) in GO. Exophthalmos and diplopia were not associated with depression nor anxiety, but orbital decompression and strabismus surgery do seem to improve QoL in GO patients.
UNASSIGNED: The results of this review suggest that altered thyroid hormone levels and autoimmunity are prognostic factors for depression and anxiety in GO. With regard to the visual and disfiguring aspects of GO as contributing factors for depression and anxiety, no decisive conclusions can be made.

Systemic diseases can cause heart block owing to the involvement of the myocardium and thereby the conduction system. Younger patients (<60) with heart block should be evaluated for an underlying systemic disease. These disorders are classified into infiltrative, rheumatologic, endocrine, and hereditary neuromuscular degenerative diseases. Cardiac amyloidosis owing to amyloid fibrils and cardiac sarcoidosis owing to noncaseating granulomas can infiltrate the conduction system leading to heart block. Accelerated atherosclerosis, vasculitis, myocarditis, and interstitial inflammation contribute to heart block in rheumatologic disorders. Myotonic, Becker, and Duchenne muscular dystrophies are neuromuscular diseases involving the myocardium skeletal muscles and can cause heart block.

UNASSIGNED: Iodine serves as a crucial precursor for the synthesis of thyroid hormones and plays an import role in both pregnant women and their offspring. The relationships between iodine nutritional status and maternal thyroid function and neonatal outcomes remain inconclusive in areas with adequate iodine nutrition. This study aims to investigate their correlations.
UNASSIGNED: Blood, morning urine and 24-hour urine were collected from the pregnant women to measure thyroid functions, serum iodine concentration (SIC), morning urine iodine concentration (UIC) and 24-hour urine iodine excretion (24-hour UIE). Indicators of their offspring\'s neonatal indexes were recorded.
UNASSIGNED: A total of 559 pregnant women were enrolled in this study. The iodine indicators including Tg, 24-hour UIE and morning UIC were significantly different among the euthyroid pregnant women and those with different thyroid disorders. The levels of FT3, FT4, and SIC exhibited a gradual decline and the concentration of TSH exhibited a gradual increase trend throughout the progression of pregnancy in euthyroid pregnant women. There were no significant differences in neonatal outcomes and neonatal TSH values among euthyroid pregnant women and thyroid disorders pregnant women. SIC had a significant impact on maternal FT4 levels throughout all three trimesters, with varying degrees of importance observed in each trimester. TSH level emerged as the primary determinant of FT4 during the first trimester, while SIC exerted a predominant influence on FT4 levels in the second and third trimesters. The prevalence of thyroid disorders in pregnant women was the lowest when the SIC of pregnant women was probable in the range of 60~70 μg/L, 24-hours UIE was in the range of 250~450 μg, and Tg was in the range of 9~21 μg/L. Maternal TSH exhibited a notable influence on neonatal TSH levels, particularly at the 50th and 75th quantiles. Among the iodine nutritional indicators, SIC and morning UIC demonstrated higher AUC values for abnormal FT4 and TSH, respectively.
UNASSIGNED: The iodine nutrition status of pregnant women exerts an impact on their thyroid function and prevalence of thyroid disorders, and neonatal TSH was affected by maternal TSH. SIC may be a better indicator for iodine nutritional assessment than other indexes.

BACKGROUND: Thyroid nodules are a common clinical challenge, with a significant proportion being cancerous. Fine-needle aspiration cytology (FNAC) is widely used for diagnosis but has limitations. Ultrasound has emerged as a promising tool for distinguishing between benign and malignant nodules. This study aims to compare the diagnostic accuracy of ultrasonography (USG) and FNAC in diagnosing malignant thyroid swelling using postoperative histopathological examinations as the gold standard.
METHODS: A diagnostic accuracy study was conducted over 1.5 years at Rajendra Institute of Medical Sciences, Ranchi, India. A total of 132 patients with thyroid swellings were included. Patients underwent USG and FNAC, and 99 patients subsequently underwent surgery and histopathological examination. Statistical analysis was performed to evaluate the performance of USG and FNAC, including sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV).
RESULTS: The study encompassed 132 patients, predominantly 94 (71.21%) females. Most patients, i.e., 76 out of 132 (57.58%), were aged 30-50 years, with an average age of presentation at 41 years. Socioeconomic status revealed 120 (90.9%) belonging to Classes II and III. USG and FNAC exhibited sensitivities of 77.4% and 90.3%, specificities of 94.1% and 98.5%, and accuracies of 88.9% and 96.0%, respectively. FNAC demonstrated superior diagnostic performance metrics compared to USG, with higher PPV and NPV, indicating its stronger ability to correctly identify true-positive cases. Ultrasound features and FNAC findings showed significant associations with biopsy results, reaffirming their utility in diagnosing thyroid nodules.
CONCLUSIONS: FNAC emerged as a highly accurate diagnostic tool for distinguishing between benign and malignant thyroid nodules, outperforming USG. Understanding demographic and clinical characteristics can aid in the timely diagnosis and management of thyroid disorders. Further research is warranted to enhance diagnostic algorithms and optimize patient care in resource-constrained settings.

UNASSIGNED: A growing body of evidence indicates a strong association between exogenous thyroid hormone (ETH) and brain health. Establishing the potential relationship between ETH therapy and dementia symptoms is crucial for patients with thyroid disorders.
UNASSIGNED: In this study, we investigate the potential association between ETH therapy and dementia symptoms by exploring the Food and Drug Administration Adverse Event Reporting System (FAERS) database.
UNASSIGNED: Disproportionality analysis (DPA) was conducted using postmarketing data from the FAERS repository (Q1 2004 to Q4 2023). Cases of dementia symptoms associated with ETH therapy were identified and analyzed through DPA using reporting odds ratios and information component methods. Dose and time-to-onset analyses were performed to assess the association between ETH therapy and dementia symptoms.
UNASSIGNED: A total of 9889 cases of ETH-associated symptoms were identified in the FAERS database. Dementia accounted for a consistent proportion of adverse drug reactions each year (3.4%-6.3%). The DPA indicated an association between ETH therapy and dementia symptoms, which remained significant even across sex, age, and indications. The median time-to-onset of dementia symptoms was 7.5 days, and the median treatment time was 40.5 days. No significant dose-response relationship was observed.
UNASSIGNED: This study provides evidence for a link between ETH therapy and dementia. Clinicians are therefore advised to exercise vigilance, conduct comprehensive monitoring, and consider individualized dosing to mitigate potential reactions to ETH drug administration.

The aim of this review is to discuss the several interconnections between thyroid autoimmunity and type 1 diabetes in terms of epidemiology, immunoserology, genetic predisposition, and pathogenic mechanisms. We will also analyze the impact of these conditions on both male and female fertility. A literature search was carried out using the MEDLINE/PubMed, Scopus, Google Scholar, ResearchGate, and Clinical Trials Registry databases with a combination of keywords. It was found that the prevalence of thyroid autoantibodies in individuals with type 1 diabetes (T1DM) varied in different countries and ethnic groups from 7 to 35% in both sexes. There are several types of autoantibodies responsible for the immunoserological presentation of autoimmune thyroid diseases (AITDs) which can be either stimulating or inhibiting, which results in AITD being in the plus phase (thyrotoxicosis) or the minus phase (hypothyroidism). Different types of immune cells such as T cells, B cells, natural killer (NK) cells, antigen presenting cells (APCs), and other innate immune cells participate in the damage of the beta cells of the islets of Langerhans, which inevitably leads to T1D. Multiple genetic and environmental factors found in variable combinations are involved in the pathogenesis of AITD and T1D. In conclusion, although it is now well-known that both diabetes and thyroid diseases can affect fertility, only a few data are available on possible effects of autoimmune conditions. Recent findings nevertheless point to the importance of screening patients with immunologic infertility for AITDs and T1D, and vice versa.

Cowden syndrome is a rare genetic anomaly mostly attributed to mutations in the Phosphatase and Tensin (PTEN) Homolog gene. This illness manifests with a diverse array of symptoms that impact several physiological systems and an increased susceptibility to various forms of malignancy. The patient typically exhibits mucocutaneous lesions and a heightened vulnerability to the formation of neoplasms, specifically thyroid carcinomas. The inclusion of thyroid disorders, such as Graves\' disease, introduces complications to the management procedure, necessitating a complete approach that includes many healthcare practitioners to guarantee optimal care. Despite some advancements in the field, there remains a dearth of evidence-based recommendations for pediatric patients, encompassing individuals with Cowden syndrome and other thyroid disorders. The current investigation focuses on a 13-year-old female patient who presents with comorbid Cowden syndrome and Graves\' disease. We emphasize the challenges associated with the diagnosis and treatment of these illnesses. A collaborative and multidisciplinary team approach was used to administer therapeutic approaches, such as total thyroidectomy, emphasizing the essential requirement for interdisciplinary cooperation among healthcare providers. Continual research endeavors play a pivotal role in elucidating the optimal management protocols and augmenting outcomes for this particular cohort of individuals.

Lung cancer (LC) is a serious health problem worldwide. Survival outcomes have improved over time due to the widespread use of novel therapeutic agents, including immune checkpoint inhibitors (ICIs). Endocrine immune-related adverse events (e-irAEs) are common in LC patients treated with ICIs. We performed a retrospective study of patients with LC who received treatment with ICIs at a tertiary referral center between January 2014 and October 2023. In total, 983 LC patients were included in the study. E-irAEs presented at a median time of 4.1 months and included hypothyroidism (15.6%), hyperthyroidism (4.3%), adrenal insufficiency (0.4%), hypophysitis (0.4%), and diabetes mellitus (0.2%). These toxicities were not related to the duration of treatment or the type of ICIs. Most (97.6%) e-irAEs were mild (grade 1-2). Median overall survival (OS) was higher in LC patients who experienced e-irAEs (31.6 months) compared to those who did not (10.8 months). The difference remained statistically significant in the 3-month (HR: 0.42) and 6-month landmark analysis (HR: 0.51). The OS advantage was observed in both patients with NSCLC (HR: 0.36) and SCLC (HR: 0.27). Additional research is needed to validate the role of e-irAEs as an independent predictor of survival outcomes in patients with LC.

Introduction The decreased thyroid-stimulating hormone (TSH) levels affect almost every nucleated cell in our body, which directly affects the basal metabolic rate (BMR). It tends to affect multiple organ systems in the human body. In recent times, there have been changes in lifestyle and the consumption of processed foods has increased. Thus, cholelithiasis and hypothyroidism are being encountered frequently, even in rural populations. In recent times, the overt clinical presentation of hypothyroidism is rare due to early diagnosis and treatment of the subclinical hypothyroidism state itself. Aim The aim is to determine the correlation between cholelithiasis and hypothyroidism. Methods This was a cross-sectional study done on the patients presenting to the surgical department at Acharya Vinoba Bhave Rural Hospital affiliated to Jawaharlal Nehru Medical College, Sawangi (Meghe), Wardha, Maharashtra, India between the duration from December 2020 to December 2022, having gallstone disease or with symptoms suggestive of gall bladder stones. The admitted patients were then evaluated for hypothyroidism by thyroid profile tests, and the results were documented. Using the collected data, factors such as clinical spectrum, correlation between cholelithiasis and hypothyroidism, relation with the demographic data, and body mass index (BMI) were studied. Results A total of 52 gallstone patients were included in the study. A greater number of patients were found to be above the age of 40 years (82.7%), with female preponderance (61.5%). More patients with cholelithiasis were from the group with having BMI more than normal (57.6%). More patients having both cholelithiasis and hypothyroidism were also from the group with having BMI more than normal. Most symptomatic patients complained of pain in the right hypochondriac region (88.5%). Of these 52 patients, nine (17.3%) were found to have hypothyroidism (seven were subclinical, two patients had overt clinical symptoms and signs) and the remaining 43 patients were euthyroid. Conclusions Our study supports that there is a correlation between cholelithiasis and hypothyroidism. Out of all the 52 patients, nine had hypothyroidism, seven were subclinical, and two had overt symptoms. Thus, we conclude that there is a correlation between cholelithiasis and hypothyroidism.
