CONTEXT: Thyroid hormones are essential for energy metabolism related to thermogenesis and oxygen consumption. OBJECTIVE: This study evaluated the potential association of thyroid function including thyroid peroxidase antibodies (TPOAb) with physical activity in nationally representative data. DESIGN/SETTING/PARTICIPANTS: This retrospective cohort study used data from the Korean National Health and Nutrition Examination Survey between 2013 and 2015...

INTRODUCTION: We investigated how laparoscopic sleeve gastrectomy (LSG) affected serum levels of thyroid-stimulating hormone (TSH), free thyroxine (FT4), and free triiodothyronine (FT3) in obese patients with hypothyroidism. We additionally examined whether the dose of levothyroxine decreases as a result of weight loss in this study. MATERIALS AND METHODS: Fifty-one people with obesity who received levothyroxine treatment for hypothyroidism and underwent LSG between January 2017 and January 2023 were retrospectively examined...

BACKGROUND: Serum total testosterone (T) decreases postprandially. Postprandial salivary testosterone (SalT) responses, however, have not been studied. We report on the effect of glucose ingestion on fasting SalT concentrations. OBJECTIVE: To investigate the effect of oral glucose ingestion on fasting SalT. METHODS: Salivary and blood samples were collected between 09.00 and 09.30 and two hours after a 75g oral glucose load in 32 men with mean (standard deviation) age of 52 (5...

OBJECTIVE: Studies on the relationship between iodine, vitamin A (VA), and vitamin D (VD) and thyroid function are limited. This study aimed to analyze iodine and thyroid-stimulating hormone (TSH) status and their possible relationships with VA, VD, and other factors in postpartum women. METHODS: A total of 1,311 mothers (896 lactating and 415 non-lactating) from Hebei, Zhejiang, and Guangxi provinces were included in this study. The urinary iodine concentration (UIC), TSH, VA, and VD were measured...

PURPOSE: To investigate the correlation between thyroid-related hormones and diabetic retinopathy (DR) in euthyroid patients with type 2 diabetes mellitus (T2DM). PATIENTS AND METHODS: Patients with T2DM admitted to our hospital between January 2023 and June 2023 were retrospectively analyzed. The patients were divided into DR and non-diabetic retinopathy (NDR) groups according to whether DR occurred. Thyroid function-related hormones (TSH, FT3, and FT4), blood glucose indices (FBG and HbA1c), and blood lipid indices (HDL-C, LDL-C, TC, and TG) of the two groups were analyzed by univariate and multivariate logistic regression to explore the risk factors for DR...

The level of thyroid hormones is often changed in uncontrolled diabetic patients. Screening for Thyroid dysfunction (TD) among patients with Type 2 Diabetes mellitus (T2DM) should be performed considering the increased prevalence of thyroid disorders. This cross-sectional comparative study was conducted in outpatient department of Endocrinology and Medicine, Mymensingh Medical College Hospital, Mymensingh (MMCH) from 1st March 2020 to 30th August 2021. One hundred (100) patients with type 2 diabetes along with 100 (hundred) non-diabetic controls of same age group were enrolled in the study...

AIM: This study investigated the sex-specific association between thyroid function and various insulin resistance (IR) indices, including noninsulin-based IR indices, in euthyroid adolescents. METHODS: A total of 465 adolescents (aged 12-18 years; 255 boys and 210 girls) based on data from the 2014-2015 Korea National Health and Nutrition Examination Survey were included. Serum thyrotropin (thyroid-stimulating hormone [TSH]) and free thyroxine (fT4) were used to assess thyroid function, whereas the homeostasis model assessment of insulin resistance (HOMA-IR), quantitative insulin-sensitivity check index (QUICKI), glucose/insulin ratio (GIR), triglyceride-glucose (TyG) index, and triglyceride/high-density lipoprotein cholesterol (TG/HDL-C) ratio were used to assess IR...

Major depressive disorder (MDD) and obesity are two serious public health problems. Although there have been some research on both, there have few studies on differences in obesity among MDD patients at different ages of onset. The study aims to evaluate the prevalence and factors associated with obesity in MDD patients at different ages of onset. This study totally recruited 1718 first-episode drug-naive MDD patients aged from 18 to 60 years. All subjects were divided into two subgroups: early adulthood onset (EAO, 18-45 years) and mid-adulthood onset (MAO, 45-60 years)...

OBJECTIVE: Previous research on the correlation between thyroid function and carotid plaque has revealed conflicting results, possibly attributable to the sensitivity of thyroid hormone indices. In this study, we aimed to analyze the association between thyroid hormone sensitivity indices and the risk of carotid plaque development in a Chinese health check-up population. METHODS: A total of 19,388 health check-up subjects were included in this study (mean age: 50...

OBJECTIVE: An alterable risk factor for hyperuricemia is obesity. Additionally, obese persons may have a moderate form of acquired resistance to thyroid hormones. Thyrotropin (TSH), thyroid hormones, and obesity all interact subtly. However, the connection between thyroid hormone sensitivity and hyperuricaemia in obese patients both before and after laparoscopic sleeve gastrectomy (LSG) has not yet been clarified. The objective of our study was to investigate the connection between impaired thyroid hormone sensitivity and elevated uric acid (UA) levels before and after LSG...

Central congenital hypothyroidism (CH) can occur as an isolated deficiency or as part of combined pituitary hormone deficiency. Unlike primary CH, central CH cannot be detected by newborn screening (NBS) using dry filter paper blood TSH levels, and early diagnosis remains challenging. In this study, the clinical and genetic backgrounds of patients with isolated central CH were determined through a questionnaire-based survey among members of the Japanese Society for Pediatric Endocrinology. The known causes of isolated central CH were studied in 14 patients, including six with previously reported patient data...

BACKGROUND: Type 2 diabetes has been described to be associated with hypothyroidism but we recently found that a decrease in pituitary sensitivity to thyroid hormone is associated with diabetes, obesity, and the metabolic syndrome.We aim to assess the longitudinal nature of this association in the population-based Study of Health in Pomerania(SHIP) in Germany. MATERIALS AND METHODS: 77% of a population-based sample of 4308 participants between 20 and 79 years was followed for 5 years...

OBJECTIVE: obesity is associated with increased Thyroid-stimulating-hormone (TSH) in non-pregnant subjects, but this phenomenon has not been fully characterized during pregnancy. Our aim was to evaluate the impact of Body-Mass-Index (BMI) on first-trimester TSH in a wide cohort of pregnant women with negative anti-Thyreoperoxidase-Antibodies (AbTPO) and its implications on uterine-artery pulsatility-index (UtA-PI), a marker of early placentation. METHODS: the study included 2268 AbTPO-negative pregnant women at their first antenatal visit...

OBJECTIVES: Pseudohypoparathyroidism type 1A (PHP1A) encompasses the association of resistance to multiple hormones, features of Albright hereditary osteodystrophy and decreased Gsα activity. Little is known about the early signs of PHP1A, with a delay in diagnosis. We report two PHP1A cases and their clinical and biochemical findings during a 20-year follow-up. CASE PRESENTATION: Clinical suspicion was based on obesity, TSH resistance and ectopic ossifications which appeared several months before PTH resistance, at almost 3 years of age...

BACKGROUND: Bariatric surgery is an effective approach to weight loss, which may also affect thyroid function. However, alteration in thyroid-stimulating hormone (ΔTSH) and thyroid hormones after bariatric surgery and the relationship between thyroid function and postoperative weight loss still remains controversial. METHODS: Data were collected from euthyroid patients with obesity who underwent sleeve gastrectomy and Roux-en-Y gastric bypass from 2017 to 2022...

Analyses of registries and medical imaging suggest that laparoscopic surgery may be penalized with a high incidence of trocar-site hernias (TSH). In addition to trocar diameter, the location of the surgical wound (SW) may affect TSH incidence. The intra-abdominal pressure (IAP) exerted on the abdominal wall (AW) might also influence the appearance of TSH. In the present study, we used finite element (FE) simulations to predict the influence of trocar location and SW characteristics (stiffness) on the mechanical behavior of the AW subject to an IAP...

OBJECTIVE: Pregnancy is a state of physiological inflammation facilitating implantation. Early isolated hypothyroxinaemia (IH) and increased inflammation (including obesity) have been associated with severe obstetric complications. The current study evaluated the association between IH, low ferritin and inflammation parameters (interleukin 6 (IL-6), C-reactive protein (CRP), human chorionic gonadotrophin (hCG) and obesity. Moreover, the course of these parameters throughout pregnancy was evaluated in relation to IH...

Background: Hypothyroidism (hT) presents heterogeneous symptoms and findings. Evidence on this topic comes mainly from heterogeneous populations in terms of disease duration, residual thyroid function, and comorbidities. Therefore, it would be useful to assess systemic inflammation in a homogeneous hT population. The aim of this study was to investigate inflammation in a population that underwent standardized controlled hT. Methods: We recruited thyroidectomized patients diagnosed with thyroid cancer who were otherwise fit and healthy, showing hypothyroidism before I131 treatment using a standard protocol of LT4 withdrawal...

INTRODUCTION: Worldwide, the rates of childhood obesity have risen dramatically in recent decades. Obesity may cause serious sequelae during childhood and throughout adulthood. Insulin resistance is prevalent metabolic abnormality in pediatric obesity. The Pediatric Obesity Clinic was established in 2011 at the Children's Medical Center, Landspítali University Hospital. This study aimed to observe metabolic abnormalities and insulin resistance in blood values of children receiving obesity treatment...
