OBJECTIVE: To determine distribution of COPD assessment categories and physicians' adherence to Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2013 strategy in Turkish COPD patients.

METHODS: A total of 1,610 COPD patients (mean [standard deviation] age: 62.6 [9.9] years, 85.7% were males) were included in this multicenter, non-interventional, cross-sectional study. Patients were categorized via GOLD 2013 strategy document. Consistency between reported and re-classified ...

The objective of this study is to describe the clinical status, procedural interventions, and outcomes of critically ill patients with poisoning and snake bite injuries presenting to a tertiary-care emergency department for treatment with therapeutic plasmapheresis. Records of 20 patients who presented to our academic emergency department over a 2-year period and who underwent plasmapheresis for poisoning or snake bite were retrospectively reviewed. Plasmapheresis was performed using ...

BACKGROUND/PURPOSE: In this study, an investigation was performed on the ovarian tissue of rats subjected to ischemia-reperfusion for the effect of famotidine on certain parameters of oxidation-antioxidation, cell DNA damage, and histological appearance.

METHODS: The effects of famotidine on certain parameters of oxidation-antioxidation (total glutathione [tGSH], superoxide dismutase [SOD], malondialdehyde) and cellular DNA injury in the ovarian tissue of rats subjected to ...

BACKGROUND: Considerable evidences have linked oxidative damage and cancer. In this article, superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSHPx) activities, and malondialdehyde (MDA) and nitric oxide metabolites' levels (NO(x)) were investigated in patients with stomach cancer.

METHODS: All measurments were done by spectrophotometric techniques.

RESULTS: We observed a significant decrease in the activities of SOD and CAT in tumour tissues when compared with control ...

PURPOSE: Postoperative hematoma remains an uncommon but potentially life-threaten complication of thyroid surgery. The aim of this study is to assess the efficacy of Ankaferd Blood Stopper (ABS) in comparison to hemostasis by conventional technique (HCT) for the controlling of oozing-type bleeding following total thyroidectomy.

METHODS: We randomized 61 patients with benign euthyroid multinodular goiter who underwent total thyroidectomy subject to one of the two different hemostasis ...

Snake bites are leading causes of morbidity and mortality worldwide, especially in rural areas. Therapeutic plasma exchange has been used in the treatment of many different conditions such as immunologic diseases, toxicologic disorders, and snake envenomation. The aim of this study is to evaluate the efficacy of plasma exchange treatment on clinical status, outcomes, and discharge of patients who were bitten by venomous snakes. The study was conducted retrospectively in the Emergency ...

Primary cutaneous diffuse large B-cell lymphoma is an uncommon type of non-Hodgkin lymphomas. A 51-year-old man had 2 gradually enlarging reddish, firm, and painless cutaneous-subcutaneous masses surrounded with some erythematous patches on his back for 3 years. Skin biopsy result was consistent with diffuse large B-cell lymphoma. FDG PET/CT was performed for staging and demonstrated bilaterally increased FDG uptake in the cutaneous masses with hypermetabolic left axillary lymph nodes. ...

Otoacoustic emissions (OAEs) are non-invasive, easy to apply and objective test methods which are widely used to determine the presence of hearing in audiology clinics. Under certain circumstances, the study should be applied under general anesthesia. The aim of this study was to determine the influence of new short-acting inhalation agents, desflurane and sevoflurane, on OAE in humans. These short-acting agents are widely used in general anesthesia. Thirty-one healthy patients who ...

Reconstruction of anomalous portal vein branching (APVB) during right lobe living donor liver transplantation (LDLT) can be challenging. The goal of this article is to describe our surgical technique, named the Malatya Approach, in case of APVB during right lobe LDLT. The technique unifies the APVB and obtains a funnel-shaped common extension with a circumferential fence by a saphenous vein conduit. In total, 126 (10.6%) of 1192 right lobe grafts had APVB that were divided into 2 groups ...

BACKGROUND AND AIMS: Familial hypercholesterolemia (FH) is a common genetic disease of high-level cholesterol leading to premature atherosclerosis. One of the key aspects to overcome FH burden is the generation of large-scale reliable data in terms of registries. This manuscript underlines the important results of nation-wide Turkish FH registries (A-HIT1 and A-HIT2).

METHODS: A-HIT1 is a survey of homozygous FH patients undergoing low density lipoprotein (LDL) apheresis (LA). A-HIT2 is ...

Chromatin crosslinking facilitates the detection in selected genomic regions of structural variants missed by existing approaches

BACKGROUND: Homozygous familial hypercholesterolaemia (HoFH) is a rare inherited disorder resulting in extremely elevated low-density lipoprotein cholesterol levels and premature atherosclerotic cardiovascular disease (ASCVD). Current guidance about its management and prognosis stems from small studies, mostly from high-income countries. The objective of this study was to assess the clinical and genetic characteristics, as well as the impact, of current practice on health outcomes of ...

Classical Hodgkin lymphoma (cHL) is considered a curable disease; however, in approximately one-third of the responding patients, the disease relapses following completion of therapy. One of the drugs that have been approved for the treatment of relapsed/refractory cHL is nivolumab, an immune check point inhibitor that shows its effects by blocking the programmed death 1 (PD-1) receptor. In this study, we present a retrospective “real-life” analysis of the usage of nivolumab in patients ...

Voltage limit violation represents a crucial power system problem, and many Volt/VAR control (VVC) strategies have been proposed to tackle violations. However, no comprehensive VVC strategy is available for use under all possible system operating conditions. This paper presents a generic solution to the VVC problem of the systems with wind-based renewable distributed generations (DGs) with the primary goal of determining an optimal control strategy based on system status, identified ...
