Background: Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a comprehensive syndrome with endocrine and metabolic complications. This review aims to explore the correlation between thyroid hormone levels and the severity of OSAHS in patients.
Methods: The protocol for this meta-analysis has been registered on PROSPERO. Searches were carried out from the inception of the databases to July 18, 2023, utilizing 6 databases (PubMed, CNKI, EMBASE, Web of Science, Cochrane Library, China Biology Medicine, and Wanfang). Standardized mean difference (SMD) and correlation coefficients were used as the effect size measures. Additionally, random effects or fixed effects models were used for pooled analysis. Moreover, data were statistically evaluated with the help of STATA 11.0 and R 4.1.3.
Results: This study included 23 articles that satisfied the pre-defined criteria. The prevalence of hypothyroidism and subclinical hypothyroidism in OSAHS patients was 6% and 8%, whereas hyperthyroidism had a prevalence of 2%. Moreover, thyroid hormone levels in OSAHS individuals exhibited no significant difference relative to healthy subjects. Subgroup analysis based on disease severity also established no significant changes in thyroid hormone levels between OSAHS individuals and controls. There was no significant correlation between the Apnea-Hypopnea Index (AHI) and free triiodothyronine (FT3), serum thyroid stimulating hormone (TSH), and free thyroxine (FT4) levels.
Conclusion: The prevalence of thyroid dysfunction is relatively low in OSAHS individuals. Thyroid hormone levels show no significant difference between OSAHS patients and healthy subjects. Furthermore, there is no significant correlation between AHI and serum TSH, FT3, and FT4 levels. Based on existing data, the relationship between OSAHS and thyroid function remains controversial, and further in-depth research is warranted to validate the connection and elucidate the underlying mechanisms.

Introduction: Anti-thyroid peroxidase antibodies (TPO-Ab) are detectable in almost all patients with autoimmune thyroid disease or Hashimoto's thyroiditis (HT) but may also be present in healthy individuals. HT affects women to a greater extent than men and can lead to overt hypothyroidism, which may increase the risk of miscarriage. There are no local data available on the prevalence of TPO-Ab among healthy women in the United Arab Emirates.

Isolated ectopic secretion of corticotropin-releasing hormone (CRH) is an exceedingly rare cause of Cushing's syndrome (CS), accounting for fewer than 1% of cases. Ectopic CS is an uncommon but potentially life-threatening condition that often necessitates urgent diagnostic evaluation and treatment. Hormonal testing may suggest a pituitary origin, complicating the diagnostic process.

Objective: This study aimed to investigate comorbidity patterns and potential pathogenic mechanisms in patients with Hashimoto's thyroiditis (HT).
Methods: Patients with HT who visited the outpatient clinic of the Thyroid Department at Dongzhimen Hospital, Beijing University of Chinese Medicine, between June 2021 and December 2024 were included. Association rule analysis and logistic regression analysis were performed using SPSS 25.

Thyroglossal duct carcinoma is a rare clinical condition, accounting for only 1% of operated cases. It is characterized by ectopic thyroid adenocarcinoma developing within thyroglossal duct cysts (TGDCs). Among these, papillary thyroid carcinoma is the most frequently reported pathological type.

Humans' exposure to arsenic (As) has been associated with the development of various diseases. Some health effects may be mediated by arsenic-induced toxicity to the thyroid and endocrine systems, but its underlying mechanisms remain unclear. The overall aim of our study was focused on using sodium arsenite (NaAsO)-exposed rats to investigate the involvement of the phosphatidylinositol 3-kinase (PI3K) and transcription factor NF-E2-related factor 2 (Nrf2) pathways in toxicity to the thyroid and endocrine systems.
