Purpose: Accurately predicting the expected duration of time until total knee replacement (time-to-TKR) is crucial for patient management and health care planning. Predicting when surgery may be needed, especially within shorter windows like 3 years, allows clinicians to plan timely interventions and health care systems to allocate resources more effectively. Existing models lack the precision for such time-based predictions.

Aim: Emerging anti-obesity pharmacotherapy provides an option to correct maladaptive physiological and hormonal changes associated with obesity. One of the widely used medications in this context is glucagon-like peptide 1 (GLP-1) agonists. However, the misuse of these medications without any guidance and monitoring of lifestyle modifications can lead to unfavorable outcomes.

In recent decades, utilization of renewable energy resources, including ocean waves, has been promoted as part of a global effort to transition away from the use of fossil fuels. This is largely due to the accompanying greenhouse gas emissions and its catastrophic impacts on the environment, which are expected to worsen with the changing climate. Energy from ocean waves can be harnessed and converted into electricity with devices referred to as wave energy converters (WECs).

We report a 46 XX male syndrome diagnosed after failure of gonadotropin therapy taken for hypogonadotropic hypogonadism due to a pituitary macroadenoma. A 39-year-old man with a non-functioning pituitary macroadenoma was admitted to our clinic due to vision loss and infertility. After pituitary surgery, vision loss improved while infertility still existed.

Background: In diagnosis of neurodegenerative diseases, the three-dimensional magnetic resonance imaging (3D-MRI) has been heavily researched. Parkinson's disease (PD) is one of the most common neurodegenerative disorders.

New Method: The performances of five different classification approaches using five different attribute rankings each followed with an adaptive Fisher stopping criteria feature selection (FS) method are evaluated.

Three-dimensional magnetic resonance imaging (3D-MRI) has been effectively used in the diagnosis of progressive neurodegenerative diseases including Parkinson's disease (PD). Pre-processing of 3D-MRI scans plays an important role for post-processing. In this paper, voxel-based morphometry (VBM) technique is used to compare morphological dierences of PDs versus healthy controls (HCs) in gray matter (GM) and white matter (WM).

Recent studies imply that euthyroid Hashimoto's thyroiditis (HT) might be related with impaired HRQoL, depression and anxiety. Ninety three patients with euthyroid HT and 31 age- and gender-matched euthyroid control subjects were enrolled into this study. SF-36 questionnaire, Beck Depression Inventory and Beck Anxiety Inventory tests were used for evaluating HRQoL, depression and anxiety.

Objective: As a consequence of hypercortisolism, Cushing syndrome (CS) is frequently observed with other diseases that are associated with atherosclerosis, including diabetes mellitus, dyslipidemia, hypertension, and obesity. Cardiovascular disease (CVD) is the primary cause of mortality and morbidity in CS. We investigate CVD risk markers such as asymmetric dimethylarginine (ADMA), lipoprotein-associated phospholipase A2 (Lp-PLA2), highsensitive C-reactive protein (hsCRP), homocysteine, lipid levels, ankle-brachial index (ABI), and carotid intimamedia thickness (CIMT) in CS.

Purpose: Thyroglobulin (Tg) assessment in the needle washout after fine-needle aspiration biopsy (FNAB) of a suspicious neck lymph node (LN) is known to improve the diagnostic accuracy in patients with papillary thyroid cancer (PTC). However, there is still controversy on the best diagnostic cut-off levels for FNAB-Tg and whether thyroglobulin antibody (TgAb) positivity affects FNAB-Tg. The objectives of this study were to determine (i) the diagnostic power of different cut-offs for FNAB-Tg and (ii) if serum TgAb(+) negatively affects the FNAB-Tg evaluation.

Free 25-hydroxyvitamin D [25(OH)D] is suggested to be important in the determination of vitamin D deficiency, since vitamin D-binding protein (VDBP) may affect total 25(OH)D levels. There are no data about free 25(OH)D concentrations in acromegaly. We aimed to investigate serum VDBP and total and free 25(OH)D levels in patients with acromegaly in comparison with control subjects.

Selenoprotein P concentrations have been found to be associated with insulin resistance and elevated in patients with type 2 diabetes mellitus (DM). The aim of the present study was to investigate circulating selenoprotein P level and its possible relationship with metabolic parameters in gestational diabetes mellitus (GDM). Plasma selenoprotein P concentrations were measured in 30 pregnant women with GDM, 35 pregnant women without GDM and 22 healthy nonpregnant women.

The cardiovascular effects of short-term overt hypothyroidism are not well known. We investigated proprotein convertase subtilisin/kexin type 9 (PCSK9), soluble lectin-like oxidized LDL receptor 1 (sLOX-1) and the ankle brachial index (ABI) in thyroid cancer patients with short-term overt hypothyroidism due to thyroid hormone withdrawal (THW). Twenty-one patients requiring radioactive iodine (RAI) ablation or scanning and 36 healthy control subjects were enrolled.

Background: We aimed to evaluate whether atrial electromechanical delay (AEMD) measured by tissue Doppler imaging (TDI), which is an indicator for structural and electrical remodelling of the atria, is prolonged in patients with active or inactive acromegaly, or both, compared with a control group.

Methods: A total of 34 patients with acromegaly (18 active/16 inactive) and 35 patients as a control group were enrolled. Both intra- and inter-AEMD were calculated by TDI.
