Nausea and Vomiting

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.

The study team proposes a randomized, double-blind, RCT to address the following goal: to determine the relative efficacy and adverse event profile of fosaprepitant compared to the standard of care antiemetic ondansetron. 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.

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.

The goal of this prospective, randomized, single-blinded is to learn if there is an ideal sedation protocol in cataract surgery in adults. The main questions it aims to answer are: * Does the combination of Dexmedetomidine and Propofol affect significantly Ramsay sedation scale, compared to Dexmedetomidine and compared to Propofol? * How does each sedation protocol affect hemodynamics? (Heart rate and blood pressure) * Are respiratory events more common in a certain group? * Is the surgeon's satisfaction similar among groups? * Are adverse effects (bradycardia, hypotension, nausea) more common in a certain group? Researchers will compare 3 sedation protocols : Dexmedetomidine versus Propofol versus the combination of these 2 drugs and to see if one protocol is overall superior to the others. Fentanyl will also be used in all 3 sedation protocols. Participants will : * Receive one of these three protocols * Be operated for one or both eyes * Monitored during the whole surgery and in the recovery room * Be evaluated by the Ramsay sedation scale by a trained Anesthesiologist or CRNA during surgery and in the recovery room Surgeons will be asked about how much they were satisfied.

The goal of this study is to measure the effects of using Tradipitant to treat nausea and vomiting induced by GLP-1R agonist use in adults with class I or class II obesity, or adults who are overweight with at least one weight-related condition. The study is placebo-controlled with two treatment arms.

This phase III trial studies how well domperidone works in treating patients with gastrointestinal disorders. Domperidone may help control chronic gastrointestinal disorders and their symptoms, such as pain, bloating, and nausea and vomiting, by stimulating contraction of the stomach to increase its ability to empty itself of food.

Nausea and vomiting during pregnancy represent one of the most common symptoms of pregnancy, affecting 35 to 91% of women. Most often, the symptoms are mild, without impairment of quality of life and disappear at the end of the first trimester. More severe forms constitute hyperemesis gravidarum (HG) (hyperemesis gravidarum). In approximately 35% of women, nausea and vomiting during pregnancy are disabling, alter daily life and professional activity and negatively affect family relationships. For 0.3 to 3.6% of pregnancies, this vomiting is uncontrollable and constitutes the main cause of hospitalization in the first trimester of pregnancy. Faced with the incomprehension and lack of knowledge of their illness, both in society and in the medical community, patient associations have been created in France to gain recognition for HG and raise awareness among caregivers and women about this illness and its consequences. Vomiting repeatedly for weeks, losing weight sometimes significantly, being weakened, no longer able to cope with daily life, family life and work, is what some women can experience while they are pregnant and that society tells them : "pregnancy is not an illness". Although HG is common, its real prevalence is unknown, particularly in France, because there have been few studies involving small samples. A population study is desirable because it is likely that the prevalence of these pregnancy aches differs depending on the country. This subject is important because vomiting during pregnancy has an impact on women's quality of life and their desire to become pregnant again. The main objective of this observation study is to evaluate the prevalence of pregnancy-related nausea and/or vomiting (uncomplicated or with hyperemesis gravidarum), in the general population, in the first trimester of pregnancy. The secondary objectives are: * to assess the prevalence of pregnancy-related nausea and/or vomiting (uncomplicated or with hyperemesis gravidarum), in the second and third trimesters of pregnancy, * to assess the prevalence of uncomplicated pregnancy-related nausea and/or vomiting in the three trimesters of pregnancy, * to evaluate the prevalence of hyperemesis gravidarum (with or without hospitalization) in the three trimesters of pregnancy, * to evaluate the prevalence of hyperemesis gravidarum requiring hospitalization in the three trimesters of pregnancy, * to evaluate the distribution of nausea and/or vomiting (mild, moderate and severe) according to the modified-PUQE score, in the three trimesters of pregnancy, * to evaluate the predictive factors for the occurrence of pregnancy-related nausea and/or vomiting (uncomplicated or with hyperemesis gravidarum) in the first trimester of pregnancy, * to assess health-related quality of life in the event of pregnancy-related nausea and/or vomiting (uncomplicated or with hyperemesis gravidarum), in the three trimesters of pregnancy, * and to compare health-related quality of life between women with pregnancy-related nausea and/or vomiting (uncomplicated or with hyperemesis gravidarum) and those without, in the first trimester of pregnancy.

This randomized controlled phase III trial aims to evaluate the use of electroacupuncture in combination with olanzapine-containing standard quadruple antiemetic drugs for the treatment of nausea and vomiting induced by highly emetogenic chemotherapy (HEC) in patients with breast cancer. Furthermore, it will analyze the relationship between single nucleotide polymorphism and electroacupuncture treatment for chemotherapy-induced nausea and vomiting.

This study explores the effectiveness of combining electroacupuncture with olanzapine-containing four-drug antiemetic therapy to mitigate chemotherapy-induced nausea and vomiting (CINV) in patients with breast cancer. The research aims to assess the adjunctive benefits of electroacupuncture in enhancing the antiemetic effects of conventional medication, particularly in the context of highly emetogenic chemotherapy regimens. By investigating the synergistic potential of these modalities, the study seeks to provide insights into optimizing supportive care strategies for patients with breast cancer undergoing intensive chemotherapy treatment.

To observe and evaluate the safety and effectiveness of Palonosetron hydrochloride capsule in preventing acute nausea and vomiting caused by moderate emetic chemotherapy; The characteristics of the applicable population, clinical medication and clinical benefits of Palonosetron Hydrochloride Capsules were analyzed.
