Obesity and related disorders are an increasing global health problem. Achieving and maintaining long-term weight loss through lifestyle changes and/or pharmacological interventions have not met expectations. Dietary supplements and alternative treatments have also shown limited effectiveness in this regard.

Article Synopsis
  • - This study aimed to identify factors affecting disease-free survival (DFS) in patients with medullary thyroid carcinoma (MTC), as previous research in this area has been limited.
  • - Researchers analyzed data from 257 patients, finding that 51% had persistent/recurrent disease while 49% had no evidence of disease at follow-up, with various factors like age, metastasis, and initial response influencing DFS outcomes.
  • - The key finding was that the lack of an excellent response after initial treatment is the strongest predictor of worse DFS, highlighting the need for diligent follow-up even in patients who initially respond well.

Thyroid hormones play a critical role in brain development, but paradoxically, patients with hyperthyroidism often exhibit cognitive decline and irritability. This study aims to explore the pattern of atrophy in hyperthyroid patients, changes in specific areas of the brain, including hypothalamic subfields and limbic structures, and their relationships with hormonal levels and psychometric tests. This prospective cross-sectional study involves 19 newly diagnosed, untreated hyperthyroid patients, and 15 age and gender-matched control subjects.

Introduction: To compare the pre and post-treatment pancreatic apparent diffusion coefficient (ADC) values of type II diabetes patients with control subjects, and also to evaluate its effectiveness in evaluating the response to treatment.

Methods: The study included 35 newly diagnosed type 2 diabetic patients and 35 non-diabetic participants, matched for sex and age. Insulin and metformin treatment was given to the patients.

Objectives: Despite the presumed overdiagnosis of papillary thyroid microcarcinoma (PTMC) which has resulted in a new trend toward less-extensive surgery and a preference for active surveillance, the impact of microscopic extrathyroidal extension (mETE) on the clinical outcomes of PTMC is still controversial. This study assessed the impact of mETE on the clinical outcomes of patients with classic subtype PTMC.

Methods: The data of consecutive patients who underwent thyroidectomy and were histopathologically diagnosed as classic subtype PTMC were analyzed.

The study was to evaluate the effect of radioactive iodine (RAI) treatment application time and clinical, histopathological factors on ablation success in patients with operated papillary thyroid cancer (PTC) in low and intermediate-risk. One hundred sixty-one patients with PTC in the low and intermediate-risk were evaluated. Most patients (89.

Histologically aggressive micropapillary thyroid carcinomas (PTMC) subtypes are thought to be associated with an aggressive clinical course. However, evidence for unfavorable clinical outcomes in patients with aggressive PTMC subtypes is not clear. In this study, we intended to determine the difference in clinical outcomes between patients with aggressive and non-aggressive PTMC subtypes.

Objective: Although the age at diagnosis has been suggested as a major determinant of disease-specific survival in the recent TNM staging system, it is not included in the recent American Thyroid Association (ATA) guidelines to estimate the risk of recurrence. Nevertheless, the effect of sex on differentiated thyroid carcinoma (DTC) recurrence is controversial. Therefore, this multicenter study was conducted to assess whether age at diagnosis and sex can improve the performance of the ATA 3-tiered risk stratification system in patients with DTC with at least 5 years of follow-up.

Article Synopsis
  • Hypothyroidism can lead to various neuropsychiatric issues such as depression and cognitive disorders, prompting research on its impact on white matter integrity in the brain.
  • In this study, 18 patients with hypothyroidism were compared to 14 healthy controls using tract-based spatial statistics (TBSS) to analyze changes in white matter properties through diffusion tensor imaging.
  • Results showed significant reductions in fractional anisotropy (FA) and alterations in diffusivity across several white matter tracts, suggesting that hypothyroidism may cause demyelination that correlates with clinical symptoms like depression.

Article Synopsis
  • This study investigates white matter changes in the brains of patients with untreated or newly diagnosed hyperthyroidism using advanced imaging techniques.
  • Researchers compared brain scans of 18 hyperthyroid patients to 14 healthy controls, focusing on various measurements of brain structure.
  • Findings revealed significant increases in radial diffusivity and decreases in axial diffusivity in specific brain regions, suggesting that demyelination may be a key factor in the observed brain dysfunctions associated with hyperthyroidism.
