BACKGROUND It is unclear whether preoperative thyroid-stimulating hormone (TSH) level is correlated with long-term mortality in the elderly after hip fracture surgery. We aimed to assess the association between TSH levels and 3-year mortality in these patients. MATERIAL AND METHODS We enrolled patients aged 65 and above who had hip fracture surgery and thyroid function tests upon admission from 2018 to 2019. Patients were categorized based on TSH median value, quartiles, or thyroid function status. The median follow-up time was 3.1 years. Cox proportional hazards models were used to examine the correlation between TSH levels and mortality, adjusting for covariates. RESULTS Out of 799 eligible patients, 92.7% (741/799) completed the follow-up, with 20.6% (153/741) of those having died by the end of the follow-up. No statistically significant differences in mortality risks were found when stratified by TSH median value (HR 0.88, 95% CI 0.64-1.22, P=0.448) or quartiles (HR ranging from 0.90 to 1.13, P>0.05). Similarly, when categorized based on admission thyroid function status, patients who presented with hypothyroidism, subclinical hypothyroidism, hyperthyroidism, and subclinical hyperthyroidism upon admission did not demonstrate a statistically significant difference in mortality risk compared to those who were considered euthyroid (HR 1.34, 95% CI 0.72-2.49, P=0.359; HR 0.77, 95% CI 0.38-1.60, P=0.489; HR 1.15, 95% CI 0.16-8.30, P=0.890; HR 1.07, 95% CI 0.34-3.38, P=0.913, respectively). CONCLUSIONS Admission TSH is not significantly associated with 3-year mortality in geriatric patients after hip fracture surgery.

Background: Thyroid-stimulating hormone (TSH) has been regarded as a predictor of poor outcomes in patients with acute myocardial infarction (AMI). AMI complicated by diabetes mellitus (DM) tends to have a high prevalence and a worse prognosis. We aim to evaluate the association between thyroid dysfunction and in-hospital outcomes and short- and medium-term mortality in diabetic patients with AMI., Methods: From January 2017 to November 2020, a total of 432 patients with AMI were included in this study, including 209 DM patients and 223 non-DM patients. Baseline characteristics, medical history, and laboratory parameters of patients were recorded after admission. In-hospital outcomes and 30-day mortality were recorded, and long-term mortality was recorded with a median follow-up of 34.2 ± 5.6 months., Results: Subclinical hypothyroidism (SCH) was defined as an elevated TSH level of more than with a normal range of circulating thyroid hormones. In AMI with DM group, 26/209 (12.4%) patients were complicated with SCH, these patients tend to be older and experienced worse in-hospital outcomes compared to patients without SCH, including higher rates of acute heart failure, acute kidney injury, and atrial fibrillation. Moreover, patients with SCH had a higher prevalence of 30-day mortality and long-term mortality, compared with patients without SCH., Conclusions: Diabetic AMI patients with SCH had worse in-hospital outcomes and higher 30-day and long-term mortality. Patients with diabetic AMI should pay attention to thyroid function, and SCH is an independent risk factor for short-term and long-term mortality in diabetic AMI patients.

There are a few studies and case reports that postulate a connection between hypothyroidism and reproductive disorders in bitches and an increased neonatal mortality and morbidity in puppies. Other studies, however, cannot demonstrate a connection between hypothyroidism and reproductive disorders in bitches. In this work, the relevant literature is to be checked for its evidence. The connection between hypothyroidism and reproductive disorders in the bitch, puppy mortality and neonatal morbidity to hypothyroidism will be analyzed based on a literature review. For this purpose, the available German and international "English-language" literature from 1986 to January 2023 was analyzed. It turns out that only a small amount of literature contains high levels of scientific evidence, as it mostly consists of case reports and expert opinions. In some case reports a connection between estrous abnormalities, galactorrhoea and infertility and the presence of hypothyroidism could be seen, but in experimental studies and according to the opinion of other authors the connection between hypothyroidism and reproductive disorders does not exist. A negative influence of hypothyroidism on the birth process could not be clearly proven. In an experimental study, although the duration and intensity of uterine contractions were longer and weaker in animals with hypothyroidism, the interval between pup births was not affected. Only in the area of neonatal mortality and morbidity a connection with the hypothyroidism of the dam could be demonstrated. The puppies of affected bitches showed a lower birth weight and were weaker than puppies of euthyroid bitches. The importance of hypothyroidism for fertility in the bitch has not yet been documented in the literature, but this endocrinopathy seems to have an influence on neonatal vitality., Competing Interests: Die Autoren bestätigen, dass kein Interessenkonflikt besteht., (Thieme.

Background: Chronic systolic heart failure (CSHF) is a significant health burden with high morbidity and mortality. The role of subclinical hypothyroidism (SCH) in the prognosis of CSHF patients remains a critical area of inquiry. This systematic review and meta-analysis aim to elucidate the impact of SCH on the prognosis of patients with CSHF., Methods: Adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, this meta-analysis employed a comprehensive search strategy across major databases including PubMed, Embase, Web of Science, and the Cochrane Library. The Patient, Intervention, Comparison, Outcome framework guided the inclusion of studies focusing on patients with CSHF, comparing those with and without SCH. Quality assessment was performed using the Newcastle-Ottawa scale. Statistical analyses assessed heterogeneity and publication bias, employing fixed-effect or random-effects models based on heterogeneity levels., Results: From an initial pool of 1439 articles, 8 studies met the stringent inclusion criteria. These studies, conducted across diverse geographical regions, highlighted the relationship between SCH and all-cause mortality, cardiac events, and subgroup differences in CSHF patients. The meta-analysis revealed SCH as a significant risk factor for all-cause mortality (HR = 1.42) and cardiac events (HR = 1.46). Subgroup analysis indicated variability in risk based on region, sample size, age, and follow-up duration. Sensitivity analysis confirmed the stability of these findings, and publication bias assessment indicated symmetric funnel plot and nonsignificant Egger test results., Conclusions: SCH emerges as a predictive factor for all-cause mortality, cardiovascular events, and rehospitalization in CSHF patients. This finding underscores the importance of screening for SCH in CSHF patients, highlighting its potential role in improving patient prognosis., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).
