Introduction: Various types of vagus nerve stimulation are employed in the treatment of a range of conditions, including depression, anxiety, epilepsy, headache, tinnitus, atrial fibrillation, schizophrenia, and musculoskeletal pain. The objective of this study was to apply vagal stimulation to the neck area using standardised cold, and then analyse the level of vascular access discomfort experienced by individuals who underwent venous cannulation from the dorsal side of the hand prior to anaesthesia.

Materials And Methods: A total of 180 patients, aged 18-75, who were scheduled to undergo elective surgery, were categorised into three distinct groups: the Sham group (Group S), the Control group (Group K), and the Cold group (Group M), with each group consisting of 60 individuals.

Many retinal cell biology laboratories now routinely use Adeno-associated viruses (AAVs) for gene editing and regulatory applications. The efficiency of AAV transduction is usually critical, which affects the overall experimental outcomes. One of the main determinants for transduction efficiency is the serotype or variant of the AAV vector.

Hematological parameters, including albumin and hemoglobin (Hb) levels and lymphocyte counts, are low-cost tests that can be used to determine inflammation and nutritional status. Recent studies have shown that inflammation plays a very important role in the development of carcinogenesis. The authors investigated whether preoperative hemoglobin, albumin, lymphocyte, and platelet (HALP) score can distinguish between benign and malignant causes in patients who are admitted to hospital and operated due to acute mechanical intestinal obstruction (AMIO).

With the aging population worldwide, the octogenarians are becoming a substantial group and since cancer incidence increases by age, this group of patients is becoming more affected. However, no distinct treatment algorithm has been established for elderly patients with cancer. The present study aimed to determine the prognostic value of several inflammatory parameters by comparing octogenarian patients treated surgically for colorectal cancer with their younger counterparts, as well as to predict and prevent age-related complications in this frail group of patients.

Background: Development or progression of inflammation in neoplastic diseases is known to be part of the disease. Lymphocyte to C-reactive protein ratio (LCR) is a new indicator showing the inflammatory state. The aim of this study is to show the clinical importance of the relationship between the preoperative LCR and the prognosis of patients with gastric cancer.

Purpose: The purpose of this study was to investigate whether it is possible to estimate systemic inflammation and intestinal ischemia in incarcerated hernias using the lymphocyte-C-reactive protein ratio (LCR).

Methods: A total of 116 patients who underwent an emergency operation due to incarcerated abdominal wall hernia were investigated retrospectively. The patients with incarcerated hernias were divided into two groups: those who did not undergo intestinal resection and those who underwent intestinal resection due to strangulation.

Aim/background: Early diagnosis of patients with colon cancer is one of the most important parameters affecting the survival of patients. In this study, we aimed to examine the effect of the age, hemoglobin (Hb), albumin, neutrophil lymphocyte ratio (NLR), thrombocyte lymphocyte ratio (PLR), and mean platelet values (MPV) on the separation of benign and malignant diseases in patients with suspected colon wall thickness (CWT) observed in abdominal computed tomography (CT) examination.

Method: The study included 116 patients between the ages of 18 and 95 who had CT examination where the colon wall could be evaluated and who also had colonoscopy.
