Purpose: Vagal nerve stimulation (VNS) is an effective treatment for patients with epilepsy, depression, and other neuropsychiatric conditions. Understanding the tissue changes associated with VNS devices is crucial for optimizing patient outcomes and device development. This study aimed to investigate the histopathological changes in the tissues surrounding the VNS generator and explore potential correlations with clinical factors and battery performance.

It takes two to tango: cardiac fibroblast-derived NO-induced cGMP enters cardiac myocytes and increases cAMP by inhibiting PDE3.

The occurrence of NO/cGMP signalling in cardiac cells is a matter of debate. Recent measurements with a FRET-based cGMP indicator in isolated cardiac cells revealed NO-induced cGMP signals in cardiac fibroblasts while cardiomyocytes were devoid of these signals. In a fibroblast/myocyte co-culture model though, cGMP formed in fibroblasts in response to NO entered cardiomyocytes via gap junctions.

Investigation of intestinal microbiome in chronic spontaneous urticaria patients.

Background: Chronic urticaria is a disorder characterized by itchy erythematous plaques with edema lasting 6 weeks or more. The prevalence is 1%, and two thirds of these cases are "chronic spontaneous urticaria (CSU)." Drugs, food, infections, and systemic diseases may be etiologic factors for CSU, although it may be idiopathic.

Double Layer Reconstruction of Exposed Cardiac Implantable Electronic Devices in Elderly Patients.

Background Elderly patients with multiple comorbidities may not be candidates for cardiac implanted electronic device (CIED) explantation in cases of exposition. Excision of all unhealthy and inflamed scar tissue results in a skin defect that must be covered. Small- to moderate-sized local skin flaps and subpectoral placement of CIEDs have been described in the literature.

The Effect of Renal Transplantation on Cardiac Functions.

Chronic renal failure is a well-known risk factor for cardiovascular poor outcome. Despite advances in dialysis and renal transplantation, these patients still have high cardiovascular morbidity and mortality. The aim of our study was to evaluate the changes in blood parameters and echocardiographic parameters of patients undergoing renal transplantation in our center.

Risk factors for left atrial appendage thrombus.

Atrial fibrillation (AF) is the most common persistent rhythm disorder that has been shown to be associated with a significant increase in stroke risk. Left atrial appendage (LAA) thrombi are responsible for most of strokes of cardiac origin. CHADS-VASc is a risk scoring system to identify patients' indications for anticoagulation in nonvalvular AF patients.

Microbial contamination and infection risks of narghile besides hazards of tobacco.

Objective: Water-pipe smoking has become a serious public health threat worldwide. In order to raise awareness of adverse effects and transmission of bacteria via water-pipe smoking, we aimed to identify the bacteria and their antimicrobial resistance profiles that colonize different parts of waterpipes.

Methods: We examined totally 182 water pipes from 7 lounges (in Turkey) used in public places and we collected 728 culture samples in total by microbiological methods.

[Markers of coagulation and fibrinolysis do not detect or predict the presence of left atrial appendage thrombus in patients with atrial fibrillation].

Objective: This study was designed to evaluate the role of hemostatic variables in arterial blood serum in left atrial thrombosis and to define any hemostatic variables, such as serum biomarkers, that could potentially reduce the need for transesophageal echocardiography.

Methods: This study included patients with non-valvular asymptomatic atrial fibrillation (AF), either paroxysmal, persistent, or chronic. The presence of an left atrial appendix (LAA) thrombus was used to form 2 groups: thrombus (+) and thrombus (-).

Reconstruction of postburn contractures due to tandir oven.

The aim of the study was to evaluate postburn contracture reconstructions caused by high temperature such as tandir. The records of our 58 patients who were operated for burn contracture between 2008 and 2018 were retrospectively reviewed. Duration elapsed after the burn, localization of contracture, surgery applied, and the recurrence rates were recorded.

Reconstruction of complex shallow defects of the extremities with free serratus musculofascial flap.

Background/aim: Thin and flexible flaps are needed for the repair of extremity tissue defects. Serratus fascia flaps are the most suitable options. There are only a few case reports and case series in the literature.

The Novel CHADS-VASC-FSH Score is Predictive of Severe Coronary Artery Disease on Coronary Angiography in Patients with Atrial Fibrillation and Unstable Symptoms.

Objective: AF may create confusion about the presence of severe or unstable coronary artery disease in cases with unstable symptoms. Novel scores and markers are needed to determine severe coronary artery disease in such patients. We aimed to test the newly developed CHADS-VASc-FSH score, developed by adding family history for coronary artery disease, hyperlipidemia, and smoking to the original CHADS-VASc score, in the prediction of severe CAD in patients with AF and unstable symptoms.

Novel Surgical Technique for Repair of Zygomatic Fractures: Lever Technique.

Background: Zygoma is a very crucial component for the anteroposterior positioning of the midface and for the maintenance of facial contours. Zygomatic fractures are considered as the second most common type of facial fractures following nasal fractures. We have developed a new reduction technique called "lever," which is based on the application of lifting force as an alternative to the methods in which the pulling force is applied.

Relationship between primary open angle glaucoma and blood pressure.

Glaucoma is commonly defined as high intra ocular pressure (≥21 mmHg) with optic neuropathy characterised by progressive loss of retinal ganglion cells which is associated with characteristic structural damage to the optic nerve and visual field loss. There are several studies investigating relation between primary open angle glaucoma (POAG) and both systemic hypertension and especially night hypotension. Our aim was to compare 24-h ambulatory blood pressure variability of patients with glaucoma followed-up in the eye outpatient clinic with that of patients free of glaucoma.

Relation of Preoperative and Postoperative Echocardiographic Parameters With Rejection and Mortality in Liver Transplant Patients.

Objectives: Survival in liver transplant after end-stage liver disease is associated with major cardiac functions. In a significant number of patients with end-stage liver disease, cardiac dysfunctions may be observed, which can include high-output heart failure, cardiac valve disease, and pulmonary venous and arterial hypertension. All of these affect perioperative survival.
