What Causes Vomiting?

Discussion Regurgitation is a passive expulsion of ingested material out of the mouth. It is a normal part of digestion for ruminants such as cows and camels. Nausea is an unpleasant abdominal perception that the person may describe as feeling ill to the stomach, or feeling like he/she is going to vomit. Anorexia is frequently observed. Nausea is usually associated with decreased stomach activity and motility in the small intestine. Parasympathetic activity may be increased causing pale skin, sweating, hypersalivation and possible vasovagal syndrome (hypotension and bradycardia). Retching or dry heaves is when there are spasmodic respiratory movements against a closed glottis. This often occurs just before emesis. Emesis, vomiting or vomition is when stomach (sometimes small intestine also) contents are propelled up the esophagus and out the mouth. It is composed of three basic parts: A deep breath is taken, the glottis closed to prevent aspiration into the lungs, while the larynx is raised which helps to open the upper esophageal sphincter. There is a decrease in respiration. The soft palate also closes to try to protect the posterior nares. The pylorus also contracts. The diaphragm contracts downward sharply which creates negative thoracic pressures. This also assists the opening of the lower esophageal sphincter and the esophagus itself. As the diaphragm contracts, the abdominal wall muscles vigorously contract which increases the intragastric pressure. As the pylorus ...

Authors: Bergland OU, Søraas CL, Larstorp ACK, Halvorsen LV, Hjørnholm U, Hoffman P, Høieggen A, Fadl Elmula FEM Abstract PURPOSE: The blood pressure (BP) lowering effect of renal sympathetic denervation (RDN) in treatment-resistant hypertension shows variation amongst the existing randomised studies. The long-term efficacy and safety of RDN require further investigation. For the first time, we report BP changes and safety up to 7 years after RDN, compared to drug adjustment in the randomised Oslo RDN study. MATERIALS AND METHODS: Patients with treatment-resistant hypertension, defined...

Conclusions: This review results revealed a low utilization of postnatal care service. Antenatal care service utilization has a positive effect on postnatal care service utilization. Policymakers and programmers better considered more antenatal care service use as one strategy of enhancing the utilization of postnatal care service. PMID: 33029402 [PubMed - in process]

Authors: Debelew GT Abstract Despite several efforts globally, the problem of perinatal mortality remained an unsolved agenda. As a result, it continued to be an essential part of the third sustainable development goals to end preventable child deaths by 2030. With a rate of 33 per 1000 births, Ethiopia has the highest level of perinatal mortality in the world. Thus, determining the magnitude and identifying the determinants are very crucial for evidence-based interventions. A community-based longitudinal study was conducted in Southwest Ethiopia among 3474 pregnant women to estimate the magnitude of perinatal mort...

This study was aimed at assessing the magnitude of induced abortion and associated factors among students in Hawassa University, southern region, Ethiopia, 2019. Methods: An institutional-based cross-sectional study was conducted among a total of 422 students selected on the bases of a probability simple random sampling method. A pretested structured questionnaire was used to collect data. Analysis was made with SPSS 20. Descriptive summary and inferential statistics (binary logistic regression) were used with a 95% CI and P value of less than 5% as a level of significance. Findings were presented in tables, figure, an...

Authors: Zhao N, Xiang Q, Liu Z, Zhao X, Cui Y Abstract INTRODUCTION: There remains an unmet need for better anticoagulants. The phase I clinical trial is of great significance in the development of anticoagulants, and the design is special. This system review aims to provide insights for the design of future phase I clinical trials of anticoagulants. AREAS COVERED: We searched the database PubMed and ClinicalTrail.gov website, to collate the phase I clinical trial of anticoagulants in healthy people. The study protocol, inclusion exclusion criteria, safety and pharmacodynamic indexes were reviewed. EXPERT ...

Authors: Siamashvili M, Davis S Abstract INTRODUCTION: Bromocriptine mesylate quick release (QR) is a dopamine D2 receptor agonist and is the only oral, primarily centrally acting drug that can be used for the treatment of adults with type 2 diabetes. AREAS COVERED: The authors describe current recommendations on the use of bromocriptine mesylate QR. Major efficacy and safety parameters of the late phase trials, including The Cycloset Safety Trial, have been identified and presented. EXPERT OPINION: Efficacy of bromocriptine mesylate QR monotherapy appears to be low but is compensated by favorable safety pr...
