Sunitinib is a multitargeted kinase inhibitor that inhibits many receptor tyrosine kinases and has been used in the treatment of gastrointestinal stromal tumors, metastatic renal cell carcinoma, and pancreatic neuroendocrine tumors. In this study, the effects of sunitinib given to rats, both alone and after stress with cisplatin, were investigated. The animals were divided into four groups - (1) control group (C) administered interperitoneally with a single dose 0.

Background: Older cancer patients are more likely to present with functional dependency, multiple comorbidities, polypharmacy, malnutrition, and cognitive dysfunction than their younger counterparts which increases the risk of elder abuse. Herein, in this single-institution observational study, we aimed to determine the frequency and risk factors of abuse in cancer patients aged 70 and above.

Methods: A total of 217 cancer patients aged ≥ 70 years who applied to the medical oncology outpatient clinic between June 2020 and January 2021 were included in this study.

BACKGROUND There is a need to identify new prognostic factors that may be used in addition to the known risk factors in gastrointestinal adenocarcinomas. In this study, we aimed to determine the expression of Necl 4 and RNase 5 biomarkers in gastric and colon adenocarcinomas, as well as the prognostic efficacy of these biomarkers in gastric and colon adenocarcinomas. MATERIAL AND METHODS Ninety-two cases resected due to stomach and colon adenocarcinoma were included in the study.

The prevalence of diabetes mellitus (DM) is increasing secondary to increased consumption of food and decreased physical activity worldwide. Hyperglycaemia, insulin resistance and hypertrophy of pancreatic beta cells occur in the early phase of diabetes. However, with the progression of diabetes, dysfunction and loss of beta cells occur in both types 1 and 2 DM.

Introduction: Chronic inflammation is a major risk factor in the pathogenesis of cardiovascular disease in end-stage renal disease (ESRD) patients. Epicardial adipose tissue (EAT) is the true visceral fat depot of the heart. The relationship between coronary artery disease and EAT was shown in healthy subjects and ESRD patients.

Background/aims: Fabry disease is a treatable cause of chronic kidney disease (CKD) characterized by a genetic deficiency of α-galactosidase A. European Renal Best Practice (ERBP) recommends screening for Fabry disease in CKD patients. However, this is based on expert opinion and there are no reports of the prevalence of Fabry disease in stage 1-5 CKD.

Bilirubin may have important antiatherosclerotic effects. Prediabetes (PD), the intermediate stage before diabetes mellitus, is associated with increased cardiovascular morbidity and mortality. We evaluated the relationship between serum bilirubin levels and carotid intima-media thickness (cIMT), as a surrogate marker of subclinical atherosclerosis, in patients with PD.

Introduction: Left atrium (LA) mechanical functions and atrial electromechanical delay (AEMD) times were considered independent predictors of cardiovascular morbidity in general population. Data are scant about these parameters in end-stage renal disease (ESRD) patients receiving hemodialysis (HD) and peritoneal dialysis (PD). We aimed to evaluate AEMD times and LA mechanical functions and associated risk factors in HD and PD patients.

Biomarkers such as mismatch repair proteins, CDX2, p53, and E-cadherin are blamed for colon cancers, but the relationships of these biomarkers with each other and with pathological risk factors in colon carcinoma are still not clear. The aim of this study was to evaluate the association of these biomarkers with each other by using immunohistochemical staining and to compare their expression with pathological risk factors for colonic adenocarcinoma. We also aimed to study the usability of a double panel of mismatch repair proteins.

Presented here is a case of long-term lithium use, with multiple emerging lithium-associated side effects. An 82-year-old woman was brought into the emergency department because of loss of consciousness. According to the physical examination and laboratory analyses, patient was diagnosed with lithium-associated hypercalcemia, hyperparathyroidism, nephrogenic diabetes insipidus (NDI), symptomatic sinus bradycardia, and thyroid dysfunction.

Background: The associations of serum uric acid (UA), atherogenic index of plasma (AIP) and albuminuria with cardiovascular disease have been shown. Several studies focused on association of serum UA and dyslipidemia, serum UA and renal impairment, dyslipidemia and renal impairment. However, to date, in literature, there have been no studies demonstrating the relationship between these parameters in diabetic patients together.

Background: In patients presenting with non-ST elevation myocardial infarction, we investigated the relationship of left atrial deformational parameters evaluated by 2-dimensional speckle tracking imaging (2D-STI) with conventional echocardiographic diastolic dysfunction parameters and brain natriuretic peptide level.

Material And Methods: We enrolled 74 non-ST segment elevation myocardial infarction patients who were treated with percutaneous coronary intervention and 58 healthy control subjects. Non-ST segment elevation myocardial infarction patients had echocardiographic examination 48 h after the percutaneous coronary intervention procedure and venous blood samples were drawn simultaneously.

Article Synopsis
  • Celiac disease is a long-term health problem that causes issues like diarrhea, weight loss, and anemia.
  • A 35-year-old man was diagnosed with celiac disease and told to follow a gluten-free diet, which helped him feel better.
  • There is a link between celiac disease and other health issues, but this is the first time it's been noted with something called familial multiple lipomas, which are fatty lumps under the skin.

Background: The relationship between diabetic nephropathy, visceral adipose tissue (VAT), and inflammation has been shown. The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are simple, inexpensive, and useful markers to determine inflammation. However, to date, in the literature, there have been no studies demonstrating the relationship between epicardial adipose tissue (EAT), inflammation, and albuminuria.

Introduction: Clear cell carcinomas of the thyroid gland with normal thyroid-stimulating hormone value are very rare, but clear cell changes are described in most reported cases of thyroidal lesions.

Case Presentation: In this report, we describe the case of a 50-year-old Caucasian woman with a normal thyroid-stimulating hormone level who underwent surgery to treat a multi-nodular goiter. The pathology was a clear cell variant of follicular thyroid carcinoma.

Background: Epicardial adipose tissue (EAT), visceral fat depot of the heart, was found to be associated with coronary artery disease in cardiac and non-cardiac patients. Platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) were introduced as potential markers to determine inflammation in various disorders. Recently, atherogenic index of plasma (AIP) was found to be closely associated with atherosclerosis in general population.
