Olanzapine Plus Metoclopramide for the Prevention of Opioid-Induced Nausea and Vomiting

The goal of this clinical trial is to evaluate the efficacy and safety of olanzapine plus metoclopramide in preventing opioid-induced nausea and vomiting (OINV) in adult patients with advanced cancer who are initiating strong opioid therapy. The main questions it aims to answer are: (1) Does the combination of olanzapine and metoclopramide reduce the incidence of OINV? (2)What adverse events do participants experience when taking the combination of olanzapine and metoclopramide? Researchers will compare the olanzapine-metoclopramide combination to a no prophylactic treatment control group to determine whether the combination is effective in preventing OINV. Participants will: Take olanzapine (2.5 mg/day ) and metoclopramide (10 mg three times daily) or receive no prophylaxis for 7 days; Through follow-up, nausea, vomiting, the time of the first attack of nausea and vomiting, the duration of nausea and vomiting, the use of strong opioids and adverse events were evaluated and recorded, as well as the pain score (using NRS) and quality of life (EQ-5D-5L) of the patients were evaluated at baseline and on day 7.

Chronic Nausea and Vomiting in Patients With Normal Gastric Emptying Using the Enterra® Therapy System (NAVIGATE)

The purpose of this research study is to determine if the Enterra® Therapy System can decrease nausea and vomiting symptoms and improve the quality of life for patients with chronic nausea, with or without vomiting, that have normal gastric emptying.

Barrett's Esophagitis in Anorexia Nervosa Binge/Purge Subtype

To better define the presence of Barrett's esophagus (BE) via non-endoscopic testing in an eating disorder cohort with purging (vomiting/rumination) behaviors

Mandala Painting During Chemotherapy

In addition to managing drug side effects that arise during cancer treatment, maintaining the patient's psychosocial well-being is also very important. Therefore, the aim of this project is to examine the effect of mandala painting during chemotherapy on anxiety, nausea, and comfort levels. This project aims to reduce the negative effects of chemotherapy, such as nausea, anxiety, and decreased comfort, by distracting the patient's attention through the non-invasive and non-pharmacological practice of mandala coloring in patients undergoing chemotherapy. Mandala painting is a distraction and positive focus practice. A limited number of studies conducted on cancer patients have shown that it reduces distress and improves psychological well-being. However, no study in the literature has comprehensively addressed the symptoms experienced by patients during chemotherapy, such as anxiety, nausea, intense stress, and impaired comfort. The research will be conducted on patients undergoing chemotherapy for the first time, and patients in the experimental group will engage in mandala coloring for at least 30 minutes. Data obtained from assessments conducted before and after chemotherapy will be compared with control group data. This project will provide a more comprehensive assessment of the effect of mandala painting, a non-pharmacological intervention, on the negative symptoms of patients undergoing chemotherapy for the first time. In addition to its scientific contribution, it is believed that effective symptom management can contribute to patients' well-being. Furthermore, if nausea can be controlled, the need for antiemetics during treatment can be reduced. This will also contribute to reducing unwanted drug effects and lowering costs.

The Effect of a Protective Oral Care Protocol Using Peppermint Oil Mouthwash

Hematologic malignancies are the fifth most common type of cancer in the world. Patients with hematologic malignancies receive long-term and exhausting treatments such as chemotherapy, radiotherapy, hematopoietic stem cell transplantation and supportive therapies. Chemotherapy-induced nausea and vomiting has a significant impact on the daily lives of patients and causes physiological effects such as anorexia, malnutrition, weight loss, dehydration and electrolyte imbalance. It also has a negative impact on activities of daily living and psychological status, and may lead to poor adherence to chemotherapy regimens, refusal of chemotherapy or discontinuation of treatment. Oral mucosa is one of the areas most affected by the cytotoxic damage of chemotherapy. Disruption of the oral mucosa causes nausea, vomiting and feeding problems. Patients resort to non-drug approaches to manage these problems. It is important that these non-pharmacologic approaches are supported and controlled by reliable and evidence-based studies in order to prevent adverse effects on patient outcomes. In the literature, it has been determined that peppermint oil has antiemetic, antiseptic, anti-inflammatory, analgesic, antiseptic, antioxidant, antiviral, antifungal and spasmolytic effects, protects the integrity of the oral mucosa and has positive effects on nausea-vomiting and anorexia. In this context, the aim of the study was to investigate the effect of a preventive oral care protocol with peppermint oil mouthwash on chemotherapy-induced nausea, vomiting and appetite in patients with hematologic malignancy. Research Hypotheses H01: The protective oral care protocol applied with peppermint oil in patients with hematological malignancies has no effect on the development of chemotherapy-induced nausea and vomiting. H02: The protective oral care protocol applied with peppermint oil in patients with hematological malignancies has no effect on the severity of chemotherapy-induced nausea and vomiting. H03: The protective oral care protocol applied with peppermint oil in patients with hematological malignancies has no effect on the development of chemotherapy-induced anorexia. H04: The protective oral care protocol applied with peppermint oil in patients with hematological malignancies has no effect on the severity of chemotherapy-induced anorexia. Methods: The type of study is a single-blind randomized controlled experimental study. The research will be conducted between September 10, 2025, and April 10, 2026, with patients admitted to the hematology clinic of a university hospital for chemotherapy treatment. The study will be conducted with a total of 72 people who will be randomly assigned to the intervention (n=36) and control groups (n=36) by stratified and block randomization method. Patients who are 18 years of age or older, have hematologic malignancy, with a history of at least one chemotherapy cycle, and scheduled to receive chemotherapy with high or moderate emetogenic risk agents, do not have oral mucositis before chemotherapy, do not have metastasis, are literate and volunteer to participate in the study will be included in the study. Research data will be collected using the "Patient Introduction Form", "Rhodes Nausea-Vomiting and Retching Index", "Oral Assessment Guide", "Appetite Assessment Chart \[(Visual Analog Scale (VAS)\]", "Peppermint Oil Protective Oral Care Protocol", "Food Intake Record Form", "Allergic Reaction Monitoring Form" and "Patient Monitoring Form and Antiemetic Record Chart". In addition to the routine protective oral care (saline solution mouthwash and/or sodium bicarbonate mouthwash) in the clinic, "Peppermint Oil Protective Oral Care Protocol" will be applied to the intervention group for 6 days from the start of chemotherapy treatment. Patients will receive mouthwash prepared with 1 ml of peppermint oil and 50 ml of prepared drinking water 3 times a day. Patients in the intervention group will be monitored for 6 days by evaluating oral assessment, development of oral mucositis, appetite follow-up and compliance with mouthwash. The development of allergy due to the use of peppermint oil in each mouthwash application will be evaluated. The control group will not receive any oral care intervention by the researcher and will receive routine preventive oral care in the clinic. In the evaluation of the data, descriptive statistics, Chi-square / Fisher's Exact test will be used for the relationship between categorical variables, Mann Whitney U test, Wilcoxon test, Kruskal-Wallis H test will be used for the relationship between continuous variables in groups that do not show normal distribution; one-way analysis of variance / repeated measures analysis of variance, t test for dependent and independent groups will be used in groups with normal distribution. Correlation analysis and regression analysis will be used to examine the relationship between variables.

Broadening Antiemetics Research by Comparing the Effectiveness of Fosaprepitant and Metoclopramide

The study team proposes a double-blind, comparative effectiveness, randomized controlled trial (RCT) to address the following goal: to determine the relative efficacy and adverse event profile of fosaprepitant compared to the standard of care antiemetic metoclopramide. Fosaprepitant and its active metabolite aprepitant are a relatively new class of antiemetic that exclusively acts in the central nervous system by blocking neurokinin (NK-1) which is a key signaling molecule in the centrally mediated aspects of the vomiting reflex. Currently, fosaprepitant and aprepitant both have only two United Stated Food and Drug Administration (USFDA) approved indications for nausea and vomiting: chemotherapy-induced and postoperative. Neurokinin inhibitors are highly effective and generally well-tolerated. Therefore, this class of medication may be a more appropriate medication for the millions of patients with nausea and vomiting that seek care in emergency departments (EDs). Intravenous fosaprepitant is converted to the active metabolite aprepitant on the order of minutes and is significantly cheaper to procure at this time.

Antiemetic Fosaprepitant To Remedy Nausea and Vomiting

Fosaprepitant and its active metabolite aprepitant are a relatively new class of antiemetic that exclusively acts in the central nervous system by blocking neurokinin (NK-1) which is a key signaling molecule in the centrally mediated aspects of the vomiting reflex. Currently, fosaprepitant and aprepitant both have only two United Stated Food and Drug Administration (USFDA) approved indications for nausea and vomiting: chemotherapy-induced and postoperative. Neurokinin inhibitors are highly effective and generally well-tolerated. Therefore, this class of medication may be a more appropriate medication for the millions of patients with nausea and vomiting that seek care in EDs. Intravenous fosaprepitant is converted to the active metabolite aprepitant on the order of minutes and is significantly cheaper to procure at this time. The outcome for the efficacy analysis will be no need for additional medication to treat nausea and vomiting within 2 hours of investigational medication administration. The primary outcome for the tolerability analysis will be the development of any new symptom within 2 hours of medication administration.

Marginal Ulcer Healing With Low-Thermal Argon Plasma Endoscopic Treatment

The objective of the study is to investigate the treatment of marginal ulcers with Low Thermal plasma in an endoscopic setting. By a treatment of the ulcerated areas with argon plasma with low power settings (\~ 1 W) we hypothesize that the size of the ulcers will shrink, and the healing is accelerated compared to standard of care alone. Patients will benefit from this minimally invasive approach compared to a much more invasive surgical approach that comes with higher risks and hospital stay length time. From a societal and scientific perspective, this study aims to extend the well-documented clinical benefits of plasma technology - from external wound healing to internal ulcer treatment - within an endoscopic framework. The success of this study could pave the way for broader applications of LTP in the treatment of other endoscopically accessible conditions such as peptic ulcers, duodenal ulcers and esophageal ulcers. This advancement has the potential not only to improve patient outcomes through less invasive methods, but also to position LTP as a cornerstone in the future of gastroenterological wound management strategies.

Comparison of Remimazolam and Propofol in Endoscopic Examinations and Treatments

This study aims to evaluate the efficacy and safety of Remimazolam, either used alone or in combination with Propofol, for moderate sedation anesthesia during endoscopic therapies or examinations. Additionally, it seeks to explore whether their combination can further enhance the quality of patient anesthesia and recovery outcomes.

Periorbital Massage for Nausea and Vomiting After Laparoscopic Surgery

Laparoscopic cholecystectomy is one of the commonly used surgical treatment methods for gallbladder diseases. However, many patients experience significant nausea and vomiting after laparoscopic cholecystectomy. It is observed that approximately 20% to 30% of patients experience postoperative nausea and vomiting as the most common complaint after laparoscopic cholecystectomy. This study aims to investigate the effectiveness of periorbital massage in postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy.

Postoperative Analgesia Between Paravertebral Block and Epidural Block in Esophageal Surgery

Prevention of postoperative pain is essential for the recovery of esophageal surgery. Epidural analgesia is a traditional and standard perioperative pain management for these patients. Beneficials of epidural analgesia have been widely established. However, there are still several potential disadvantages such as perioperative hypotension, failure of administration, rare but serious neurological complications. Ultrasound-guided regional nerve block has become a widely used technique due to its low degree of trauma and precise target of action. In combined with liposome bupivacaine (LB), a new long-acting local anesthetic, was proven to have a maximum duration of 72 hours, thus improving postoperative analgesia, reducing opioid consumption, and enhancing patient satisfaction. The aim of this study was to evaluate the efficacy of TPVB liposomal bupivacaine (LB) or plane bupivacaine (SB) for Overall Benefit of Analgesic Score (OBAS) after esophageal surgery.

Mechanisms of Action for the Enterra Medical Gastric Electrical Stimulator

Background: Gastric electrical stimulation applied by a surgically implanted device effectively alleviates upper gastrointestinal symptoms in the majority of individuals with medically refractory gastroparesis. Despite its efficacy, the mechanisms of action have been minimally explored in previous studies, and it is unknown why some individuals experience limited symptom-lowering effects. Aim: The investigators aim to investigate two of the potential mechanisms of action leading to symptom-reducing effects of gastric electrical stimulation: 1) possible central effects in the brainstem and brain by enhanced parasympathetic vagal activity, and 2) peripheral effects in the stomach by improved gastric accommodation. Methods: Up to thirty individuals with drug-refractory gastroparesis having an implanted gastric electrical stimulator will be enrolled in this cross-sectional and observational study. Of these, 15 will be responders (substantial symptomatic improvement) and 15 non-responders (minor symptomatic improvement). Electroencephalography (EEG) will evaluate the stimulation-induced activity in the brain and brainstem to assess whether the gastric stimulation generates evoked potentials. Electrocardiography (ECG) will investigate stimulation-induced changes in the autonomic regulation of the heart. Gastric ultrasound will investigate the effect of stimulation on stomach accommodation, contractions, and wall tension. These central and peripheral measures will be assessed during one study day before and after activating the gastric electrical stimulator, following an increase in stimulation intensity and post-meal consumption. Furthermore, results will be compared between responders and non-responders. Perspectives: Adjusting the parameters of gastric electrical stimulation based on objective markers in the brain, heart, or stomach, rather than relying on symptom fluctuations, may enhance the effectiveness of symptom improvement. In the future, these objective markers may aid in differentiating between responders and non-responders, which may lead to optimised selection criteria for surgery.

Safe Brain Initiative, Operationalizing Precision Anaesthesia

Perioperatively, patients experience an unnecessarily high level of side effects associated with their treatment. These side effects include nausea, severe pain, anxiety, and stress. Moreover, many patients develop postoperative delirium (POD) and neurocognitive dysfunctions, often resulting in long-term cognitive impairment, decreased quality of life, and increased mortality. However, physicians, nurses and their institutions do not receive structured feedback regarding these aspects of each patient's well-being. They may therefore be unable to engage in the essential cause-and-effect learning necessary to evaluate and consecutively reduce such side effects. Effective guidelines conform prevention is the proven key to shielding our patients from adverse Outcomes. The Safe Brain Initiative's high-quality routine data-for-action is a sword and accelerator for moving towards patient-centred, precision care. Thus, establishing a foundation for value-based and patient-centred healthcare development. However, a turnkey real-world solution is challenging to develop and implement and requires substantial resources. As a result, such solutions are usually beyond the scope of a single institution. The SBI platform provides high-quality, real-world data to bridge this gap. It allows monitoring and in-depth analysis of cause and effect in the day-to-day routine of individuals, departments, and institutions. The SBI's approach is continuously improved and updated. An organization called the SBI Global Society oversees the quality and precision of science through experts in the field. At SBI Hospitals and Flagship centres, Masterclasses are conducted and can be attended alongside clinical immersions. SBI Solutions manages, develops, and provides technical and service support for the Safe Brain Initiative. Its service guarantees the professional and GDPR conform management of data handling and storage as well as the user-friendly functionality of the SBI-Dashboard solutions.
