Effects of Preoperative Whey Protein and Exercise Support on Recovery After Total Hip Arthroplasty

Objective: The aim of this project is to evaluate the effects of preoperative whey protein supplementation and a physical exercise program on postoperative recovery outcomes in patients undergoing total hip arthroplasty (THA). Specifically, inflammatory markers (CRP), nutritional status (albumin), mobilization time, length of hospital stay, and physical and social functioning will be assessed. As one of the first randomized controlled trials in Turkey to focus on the preoperative period and to evaluate a combined nutrition and exercise intervention in elderly surgical patients, this study holds pioneering significance in both clinical and academic contexts. Methods: This study is designed as a randomized controlled trial. The intervention group will receive whey protein supplementation and a home-based exercise program for 14 days preoperatively, while the control group will receive standard preoperative care. Data collection will be performed preoperatively and on postoperative days 3 and 5, focusing on metabolic and functional parameters. Expected Outcomes: The findings of this study are expected to contribute to the improvement of patient care through a multidisciplinary approach, inform health policy development, and provide a foundation for larger-scale clinical research in Turkey.

A Single-Arm, Multicenter, Exploratory Clinical Study of TACE Combined With Iparomlimab and Tuvonralimab Injection (QL1706) and Lenvatinib for Perioperative Treatment of Resectable Hepatocellular Carcinoma

This is a single-arm, multicenter, exploratory clinical study evaluating the efficacy and safety of TACE combined with Iparomlimab and Tuvonralimab Injection (QL1706) and lenvatinib for perioperative treatment of resectable HCC (CNLC IIb-IIIa excluding Vp3/Vp4 or CNLC Ib-IIa with high-risk recurrence factors). Eligible subjects providing written informed consent will receive study treatment. The primary endpoint is MPR rate.

Preoperative Residual Gastric Volume

The goal of this observational study is to assess the preoperative gastric residual volume in adult patients undergoing elective surgery. The main question it aims to answer is: Does gastric residual volume, content type, and aspiration risk differ between diabetic and non-diabetic patients with similar fasting durations? Participants undergoing elective surgery will receive bedside gastric ultrasound as part of their preoperative assessment. Ultrasound images will be used to estimate gastric volume and evaluate aspiration risk.

Preoperative Oral Midazolam to Postoperative Pain Relief in Sleep Disturbance or Anxiety Patients With Colorectal Cancer

Previous studies have indicated a high incidence of sleep disturbances and anxiety symptoms in individuals with colorectal cancers prior to undergoing surgery, leading to worsened postoperative pain, slower recovery, and higher risk of chronic pain. The enhancement of sleep quality is intricately linked to reducing stress. Preoperative drugs that combine hypnosis and anti-anxiety have not been studied in colorectal cancer patients. Midazolam oral solution is safe and effective for short-term hypnotic and anti-anxiety effects in clinical preoperative settings. In the current randomized controlled clinical trial, 280 patients experiencing sleep disturbance or anxiety prior to colorectal cancer surgery will receive midazolam solution to assess its potential efficacy in reducing postoperative pain, expediting recovery, and decreasing the likelihood of chronic pain. Additionally, the study aims to explore the potential connections between midazolam administration and reductions in stress and inflammation.

Preoperative Chewing Gum on Anxiety and Postoperative Nausea and Vomiting, Gastrointestinal Function

The aim of this study was to investigate the effects of chewing gum before surgery on preoperative anxiety, postoperative gastrointestinal functions (time to first gas, time to first defecation, bowel sounds, abdominal distension) and nausea and vomiting in patients undergoing abdominal surgery. Hypotheses of the Study: In patients undergoing abdominal surgery; H1.1: The first gas output time (hour) is shorter in patients who chew gum before surgery compared to patients who do not chew gum H1.2: The first defecation time (hour) is shorter in patients who chew gum before surgery compared to patients who do not chew gum H1.3: The bowel sounds are heard shorter in patients who chew gum before surgery compared to patients who do not chew gum H1.4: The abdominal distension rate is lower in patients who chew gum before surgery compared to patients who do not chew gum H1.5: The nausea and vomiting rate is lower in patients who chew gum before surgery compared to patients who do not chew gum H1.6: Preoperative anxiety levels of patients who chew gum before surgery are lower than those of patients who do not chew gum Preoperative intervention group patients will chew sugarless gum for at least 30 minutes 30-60 minutes before surgery. The gum will be removed before going to the operating room. No intervention will be performed on control group patients, and standard care will be applied.

Camrelizumab Combined With Apatinib Mesylate and TACE in the Perioperative Treatment of Hepatocellular Carcinoma

Hepatocellular carcinoma (HCC) is the most common primary liver cancer. Hepatectomy is a curable and effective method. However, the recurrence rate is as high as 50%\~70% in 5 years after surgery. Perioperative treatment with immunotherapy combined with target therapy is expected to improve the patient's prognosis. This study aims to evaluate the efficacy, safety and tolerability of camrelizumab combined with apatinib mesylate in the perioperative period of resectable hepatocellular carcinoma. The primary purpose of this study is to evaluate 2 year event-free survival（2y-EFS） of camrelizumab combined with apatinib mesylate in the perioperative period of hepatocellular carcinoma (CNLC Ib-IIIa). The secondary research purpose is to evaluate the R0 resection rate, the rate of subjects with major pathological response, the rate of subjects with pathological complete response, event-free survival (EFS) and overall survival of camrelizumab combined with apatinib mesylate in the perioperative period of resectable hepatocellular carcinoma. The safety and tolerability is also evaluated.

Pre-operative Phentolamine Vs Intraoperative Esmolol Efficacy for Hypotensive Anesthesia in Functional Endoscopic Sinus Surgery

The aim of this study is to evaluate the efficacy of intra-operative phentolamine vs intraoperative esmolol for hypotensive anesthesia in functional endoscopic sinus surgery.
