Low-dose aspirin can prevent cerebral and cardiovascular accidents in individuals with symptomatic atherothrombotic disease, but its use is frequently limited by gastrointestinal side effects. The position of H2-receptor antagonists as a step-down therapy after healing of peptic ulcer or erosions by proton pump inhibitor is unclear. The objective of this randomized, double blinded control study was to compare the efficacy of high-dose famotidine with pantoprazole in the prevention of recurrent dyspeptic or complicated ulcer/ erosions in patients taking low-dose aspirin Low-dose aspirin can prevent cerebral and cardiovascular accidents in individuals with symptomatic atherothrombotic disease . Its use is frequently limited by gastrointestinal side effects, ranging from dyspepsia (31%) to life-threatening bleeding or perforation of gastroduodenal ulcers (3.1%) over a period of 4 years . The best approach for the secondary prevention of low-dose aspirin induced symptomatic peptic ulcer or erosions in patients who need to continue aspirin remain uncertain. At present, eradication of Helicobacter pylori infection and long-term maintenance with proton pump inhibitor PPI appears to be the best options. The position of H2-receptor antagonists (H2RA) as a step-down therapy after healing of peptic ulcer or erosions is unclear. The objective of this randomized, double blinded control study was to compare the efficacy of high-dose famotidine with pantoprazole in the prevention of recurrent dyspeptic or complicated ulcer/ erosions in patients taking low-dose aspirin.
Studies showed that combined use of clopidogrel and aspirin had a 25 % reduction of risk on myocardial infarction and stroke in patients who undergone percutaneous coronary intervention (PCI) when compared with use of aspirin alone. However, major GI bleeding rose in combined group than aspirin group. Use of proton pump inhibitor (PPI) which diminishes gastric acid secretion effectively reduces aspirin or clopidogrel associated ulcer or/and ulcer bleeding in general population and high risk patients. The investigator hypothesis is whether use of PPI can reduce ulcer and ulcer complication in patients taking both clopidogrel and aspirin. Patients are eligible if they have received PCI for their stenotic coronary arteries. Patients who had a past history of PUD without complication, who have taken aspirin or clopidogrel before enrolling for their CV disease will be allowed to enroll. Patients are excluded if they have New York Heart Association class IV heart failure, if they had contraindications to antithrombotic or antiplatelet therapy, if they have clinical severe thrombocytopenia (platelet count< 80000/mm3), if they have previous disabling, or hemorrhagic stroke or intracranial hemorrhage, if they have severe and unstable conditions in hepatic, renal, and pulmonary disease, if they have unstable and progressive malignancy, if they have epigastralgia or have a positive occult blood in stool, if they have current or recent peptic ulcer disease and take PPI or histamine receptor-2 antagonist without proving healed ulcer by scopy, if they have received a surgical intervention due to ulcer complication (bleeding, perforation, obstruction) in the past.
The aim of this study is to compare the clinical effectiveness of intravenous esomeprazole and pantoprazole in preventing recurrent bleeding in the patients with high-risk bleeding peptic ulcers after successful standard endoscopic hemostasis. Endoscopic hemostasis and proton pump inhibitor (PPI) constitute the cornerstone in the management of peptic ulcer bleeding (PUB), which remains a prevalent disorder associated with substantial morbidity and mortality. Clinical effectiveness of PPI in the management of patients with PUB has been established by compelling evidence derived from a number of randomized trials. However, whether different PPIs are equally effective has not been investigated. Esomeprazole, the S-isomer of omeprazole, may achieve faster, more profound and steady acid suppression than other PPIs, but it remains undetermined whether the superiority of pharmacologic efficacy may be translated into advantages in clinical outcomes.
Nimotuzumab (hR3) is an IgG1 humanized monoclonal antibody that recognized an epitope located in the extra cellular domain of the human epidermal growth factor receptor (EGFR). Clinical efficacy has been shown in adult with head and neck cancer. The phase I study assessed the safety, and efficacy of the combination of Nimotuzumab administered concomitantly with chemo-radiotherapy in patients with locally advanced esophageal cancer tumours.
The objective of this study is to identify the incidence rate; describe the risk factors, clinical presentation, and endoscopic treatment; assess the morbidity, mortality, and overall performance of the management of patients with actively bleeding marginal ulcers after Roux-en-Y gastric bypass (RYGB) surgery. Marginal ulceration "MU", which presents as an ulcer at the margins of the gastrojejunostomy on the jejunal side, is a common late complication after RYGB. Its incidence after RYGB ranges from as low as 0.6 to as high as 16%. In our hands with the laparoscopic hand-sewn technique for the GJ, the incidence is 1.4%. The presence of specific technical factors - staple-line dehiscence or gastro-gastric fistula, enlarged pouch, foreign material and local ischemia - and environmental factors - tobacco, NSAID´s, alcohol consumption, and H pylori infection among others - have been associated with marginal ulceration however the exact etiopathogenesis has not been completely elucidated. Similar to peptic ulcer disease (PUD), most marginal ulcers respond to medical therapy, specifically sucralfate and acid-lowering medication. In contrast, complicated marginal ulcers - perforation, bleeding, or chronicity (obstruction, penetration, and intractability)- warrants operative intervention. Early presentation of hemorrhage after RYGB is mostly related to staple-line failure and may result in either GI or intraabdominal hemorrhage. When indicated, operative interventions consist of either endoscopic therapy, re-operation, or both.
A common late complication after gastric bypass surgery is marginal ulceration that is defined as ulcers at the margins of the gastrojejunostomy, mostly on the jejunal side. Most marginal ulcers respond to medical therapy and complicated or complex ulcer disease warrants operative intervention; specifically, perforated, penetrated, obstructing, bleeding and intractable marginal ulcers require surgical intervention. Diverse operative strategies for addressing perforated marginal ulcers after gastric bypass have been described including I) Omental (Graham) patch repair, II) Revision of gastrojejunostomy, III) Irrigation and drainage, IV) any previous procedure with truncal vagotomy, V) Esophagojejunostomy, and VI) Reversal. We formally analyze our experience with the laparoscopic resection and repair of acutely perforated marginal ulcers after Roux-en-Y gastric bypass (RYGB), with or without concomitant resolution of technical risk factors for marginal ulceration. The epidemic of overweight and obesity in the United States of America along with its comorbidities continues to expand. Bariatric surgery has demonstrated to be the most effective and sustained method to control severe obesity and its comorbidities. For instance, type 2 diabetes mellitus was completely resolved in 76.8%, systemic arterial hypertension was resolved in 61.7%, dyslipidemia improved in 70% and obstructive sleep apnea-hypopnea syndrome was resolved in 85.7%. Furthermore, bariatric surgery significantly increases life expectancy (89%) and decreases overall mortality (30-40%), particularly deaths from diabetes, heart disease, and cancer.
This study is being done to see if a new approach to repair perforated ulcers in the stomach (holes in the stomach) or the first part of the intestine is possible. Traditionally, either open operations (large single incision) or laparoscopic operations (multiple small camera-guided incisions) have been used to repair perforated ulcers. Over the last ten years, some surgeons have used endoscopic equipment to assist them with performing the procedure. It is unknown if perforated ulcer repair can be done using an endoscope as the main instrument (a flexible tube with a video camera inserted into the stomach through your esophagus) to "patch" or plug the perforation. We will patch the perforation using a standard method which uses tissue from outside the stomach. A laparoscopic camera will also be used to assist our view. This study is intended to be a feasibility study to demonstrate the endoscopic technique can be safely performed Hypothesis: The primary outcome is successful completion of the procedure. Perforation is the most dangerous complication of gastroduodenal ulcer disease. It accounts for more than 70% of deaths associated with peptic ulcer disease. In addition to age and concomitant disease, intervention related complications are statistically significant predictors of death after hospital stay. Age, time to presentation and comorbidities are not factors that can be influenced. If it would be possible to reduce the impact of procedure related complications or the "second hit", that may lead to decreased morbidity and mortality.
"The purpose of this investigator-initiated study is to see if giving dextrose fluid in the veins (IV) decreases the risk of postoperative nausea and vomiting (PONV) in female urologic, gynecologic and breast outpatient surgery patients and at what blood surgery level. The reason for this study is that IV dextrose has been shown to decrease the incidence of PONV and the use of medications to treat PONV, while leading to sooner discharge after surgery. This can decrease overall healthcare cost and improving patient satisfaction."
Proton Pump Inhibitors (PPI) can prevent the recurrence of peptic ulcer in clopidogrel users. The aim of the prospective, randomized study is to investigate the efficacy of PPI in prevention of ulcer recurrence for clopidogrel users. We plan to enroll 300 clopidogrel users without baseline gastroduodenal ulcer at initial endoscopy. The patients will be randomly assigned to receive either (1) esomeprazole (20 mg qd) plus clopidogrel or (2) clopidogrel treatment alone for 6 months. The ulcer recurrence rate between the treatment groups will be compared.
The aim of this study is to determine if early angiographic embolization can forestall recurrent bleeding in selected high risk ulcers after their initial endoscopic control; to validate prospectively the investigators proposed in selecting high risk ulcers for recurrent bleeding in spite of maximal endoscopic control and profound acid suppression using high dose intravenous infusion of proton pump inhibitor; to characterize the nature of bleeding arteries in severely bleeding peptic ulcers and determine the efficacy of angiographic embolization in the prevention of recurrent bleeding and to establish safety profile of angiographic embolization as an early elective treatment to bleeding peptic ulcers. Endoscopic therapy is now the treatment of choice in patients with actively bleeding peptic ulcers and ulcers with non-bleeding visible vessels. Following endoscopic control of bleeding, we showed that the use of a high dose intravenous infusion of proton pump inhibitor (PPI) for 72 hours further reduced rate of recurrent bleeding [Lau NEJM 2000]. Recurrent bleeding still occurs in 8 to 10 percent of patients who receive the above treatment regime. The associated mortality following a rebleed is 4-10 fold higher when compared to those without recurrent bleeding. In a logistic regression model involving 1144 patients after successful endoscopic thermocoagulation to their bleeding peptic ulcers, we demonstrated that several factors independently predicted recurrent bleeding. They included hypotension, hemoglobin <10g/dl, fresh blood in the stomach, ulcer size > 2cm and active bleeding during endoscopy [Wong Gut 2003].
The investigators previously showed that the use of a high-dose intravenous PPI regimen after endoscopic control of bleeding from peptic ulcers reduced rate of recurrent bleeding, decreased the need for endoscopic and surgical interventions and in general improved patients' outcomes. A trend towards reduced mortality associated with the use of high-dose intravenous PPI was also observed. Recent clinical trials from Asia have provided evidence that high-dose oral PPIs are associated with a reduction in rebleeding. Current meta-analysis suggests that both high dose (intravenous) and low dose (oral) PPIs effectively reduce rebleeding vs placebo. However, there has been no clinical study to compare IV infusion to oral PPI in this patient population. The purpose of this clinical study is to compare the efficacy and safety of intravenous and oral Esomeprazole in patients with peptic ulcer hemorrhage who are at risk for recurrent bleeding. The investigators hypothesize that using IV infusion is superior to oral PPI. The investigators previously showed that the use of a high-dose intravenous PPI regimen after endoscopic control of bleeding from peptic ulcers reduced rate of recurrent bleeding, decreased the need for endoscopic and surgical interventions and in general improved patients' outcomes. A trend towards reduced mortality associated with the use of high-dose intravenous PPI was also observed. Recent clinical trials from Asia have provided evidence that high-dose oral PPIs are associated with a reduction in rebleeding. Current meta-analysis suggests that both high dose (intravenous) and low dose (oral) PPIs effectively reduce rebleeding vs placebo.
The purpose of this study is to determine and analyse the incidence, severity, risk factors and routine management of acute drug-induced upper gastrointestinal bleeding (UGIB) in the population of Russian patients
Is intravenous metoclopramid as effective as intravenous ondansetron in the treatment of persistent vomiting in patients with acute gastroenteritis. In this study, we will compare the efficacy of a single intravenous dose of ondansetron versus intravenous metoclopramide in the treatment of persistent vomiting in simple gastroenteritis in a larger RCT. PEC Al Saad is the main Pediatric Emergency Center in the state of Qatar with approximately 200,000 visits annually. It has a capacity of 42 observation beds providing most of the inpatient facilities except for intensive care monitoring. Patients admitted to the PEC are managed there for 48 hours or longer if needed, they are then transferred to Hamad General Hospital for further investigation and completion of their treatment. Hamad General Hospital is the main tertiary care hospital in Qatar with a capacity of around 100 pediatric beds. All acute gastroenteritis patient between 1-14 years presenting to PEC Al Saad with diarrhea, persistent vomiting , fail oral rehydration and admitted to the observation unit for intravenous hydration will be eligible for the study. Patients were excluded from the study if they had one or more of the following: Previous abdominal surgery,Suspicion of surgical abdominal,Bile stained vomitus,History of hepatic illness,Metabolic diseases, including diabetes mellitus and in-born error of metabolism,Children with shock or impending shock,Sever dehydration,Previous hypersensitivity or abnormal reaction to metoclopramide or ondansetron,Parenteral antiemetic treatment in the previous 24hrs or Seizure disorder One group will receive a single IV dose of Ondansetron after enrollment and the second group will receive a single IV dose of Metoclopramide On arrival to the PEC, patients with simple gastroenteritis will be assessed by the pediatric specialist on-call, patients with persistent vomiting who fail ORS therapy will be admitted for observation and management as usual.
The aim of this study is to compare the efficacy of a proton pump inhibitor (lansoprazole) and a histamine-2 receptor antagonist (famotidine) in preventing recurrent ulcer bleeding in patients with a history of H. pylori-negative idiopathic peptic ulcers. Peptic ulcer disease used to be caused by a bacterial infection (Helicobacter pylori) in the stomach or the use of certain painkillers (nonsteroidal anti-inflammatory drugs or NSAIDs). However, there has been an increasing trend of peptic ulcer disease with unknown cause (idiopathic ulcer) worldwide since the last decade. Studies in North America found that idiopathic ulcers accounted for 11% and 44% of all peptic ulcers. A meta-analysis of 7 US trials found that 20% of patients with H. pylori-associated ulcers had recurrent ulcers within 6 months, despite successful cure of H. pylori infection and no reported use of NSAIDs. In a pooled analysis of 6 clinical trials with a total of 2900 patients, 27% of duodenal ulcers were not associated with NSAID use or H. pylori infection. The emerging problem of H. pylori-negative idiopathic peptic ulcers is not only limited to western countries. Previously, H. pylori-negative idiopathic peptic ulcers accounted for less than 5% of peptic ulcers in Asia. A recent Korean study reported that the proportion of peptic ulcers not associated with H. pylori infection or NSAID use was over 20%.
Endoscopic hemostasis has been documented by a number of clinical studies to be effective in decreasing rebleeding, need for emergency surgery, and hospitalization days. Studies showed adjuvant treatment with proton pump inhibitor (PPI) after initial endoscopic hemostasis reduced recurrent ulcer bleeding. However, the optimal dose and route of adjuvant PPI therapy remains controversial. A recent study demonstrated frequent oral PPI offered similar acid control as currently recommended intravenous infusion PPI did in patients with bleeding ulcers. The investigators hypothesize that an frequent oral PPI treatment has similar benefit as proton pump inhibitor infusion in patient with bleeding ulcers after combined endoscopic hemostasis. Acute peptic ulcer bleeding remains a therapeutic challenge with significant morbidity and mortality. Endoscopic therapy using various modalities significantly reduces re-bleeding, need for surgery and mortality in patients with peptic ulcer bleeding. Endoscopic therapy achieves successful hemostasis in more than 90% of patients, and re-bleeding occurs in 10-30% of patients. Re-bleeding has an important impact on prognosis. Studies showed adjuvant treatment with proton pump inhibitor (PPI) after initial endoscopic hemostasis reduced recurrent ulcer bleeding. Two consensus documents have endorsed a high-dose PPI regimen (80 mg stat followed by an infusion of 8 mg/h for 72 h). The biologically plausible mechanism of benefit of such a high-dose regimen is to promote clot stability by sustaining the intragastric pH above 6. However, the optimal dose and administration route of proton pump inhibitors (PPI) for the prevention of peptic ulcer rebleeding remains unclear.
The main aim of the study is to describes the outcomes of patients with Upper Gastrointestinal Bleed (UGIB) in a real-life setting. Additionally analyse assessed predictors of outcome, including the impact of hemostatic endoscopic and pharmacologic therapies. MSD
Esomeprazole plus aspirin compared with esomeprazole alone for the treatment of aspirin-related peptic ulcers. The aims of this study are to compare esomeprazole plus aspirin with esomeprazole alone in the treatment of aspirin-related ulcers. Patients with aspirin-related peptic ulcers are randomized to receive esomeprazole (40 mg/day) plus aspirin (100 mg/day) or esomeprazole (40 mg/day) alone for 8 weeks. Follow-up endoscopy was carried out at the end of the eighth week. The primary end point was the healing of peptic ulcers.
The investigators propose to study the use of video capsule endoscopy (VCE) in the emergency department (ED) for the early assessment of acute upper gastrointestinal hemorrhage (UGIH). This pilot study will investigate the concept that VCE can be used in the ED and is useful for the diagnosis and treatment of patients with suspected UGIH. The specific endpoints that are planned include the following: (1) the detection of UGIH; (2) the presence of fresh blood; (3) and subject tolerance. An ED attending and an expert gastroenterologist will independently interpret the VCE and make determinations regarding the planned endpoints. Their respective determinations will be compared to each other and to subsequent esophagogastroduodenoscopy (EGD).
Peptic ulcer bleeding associated with ASA or NSAIDs is a major cause of hospitalization in Hong Kong. The investigators previously showed that ASA or NSAIDs accounted for about half of all cases of hospitalizations for peptic ulcer bleeding. Currently, ASA use has contributed to about one-third of the bleeding ulcers admitted to the investigators hospital that serves a local population of 1.5 million. In patients with acute coronary syndrome or acute ischemic stroke who develop ASA-induced bleeding peptic ulcers, whether ASA should be discontinued before ulcers have healed is a major dilemma. In another double-blind randomized trial, the investigators have shown that discontinuation of ASA after endoscopic treatment of bleeding ulcers was associated with a significantly increased in mortality within 8 weeks. In the absence of safer aspirins, co-therapy with a gastroprotective drug remains the dominant preventive strategy. Given the vast number of people taking ASA, however, it is only cost-effective to identify and treat those who are at high risk of ulcer bleeding and who have a strong indication for ASA use. Data from observational studies and randomized trials have consistently shown that PPIs are effective in reducing the risk of ulcer bleeding associated with ASA. Other potential preventive strategies include eradication of H. pylori infection, substitution of ASA for other non-aspirin anti-platelet drugs, and co-therapy with misoprostol or H2RAs. No dose of "low-dose" aspirin (ASA) is safe in terms of the risk if ulcer bleeding.
Primary Aim: To determine the feasibility and safety of hypotensive resuscitation for the early treatment of patients with traumatic shock compared to standard fluid resuscitation. Primary Hypotheses: The null hypothesis regarding feasibility is that hypotensive resuscitation will result in the same volume of early crystalloid (normal saline) fluid administration compared to standard crystalloid resuscitation. The null hypothesis regarding safety is that hypotensive resuscitation will result in the same percent of patients surviving to 24 hours after 911 call received at dispatch compared to standard fluid resuscitation. Early resuscitation is defined as all fluid given until 2 hours after arrival in the Emergency Department or until hemorrhage control is achieved in the hospital, whichever occurs earlier. 1. Overview This multi-center pilot trial is designed to determine the feasibility and safety of hypotensive resuscitation for the early resuscitation of patients with traumatic shock compared to standard fluid resuscitation. Blunt and penetrating trauma patients with a prehospital systolic blood pressure (SBP) ≤ 90 mmHg will be eligible. In the hypotensive resuscitation group, an intravenous line (IV) will be placed and a radial pulse will be palpated. If the radial pulse is present or the SBP is greater than or equal to 70, a 250 ml bag of normal saline will be hung and maintained at a keep the vein open rate only. If the radial pulse is absent, the 250 ml of normal saline will be given as a bolus.
This study is being done to determine the efficacies of two preventative drug combinations for postoperative nausea and vomiting in patients undergoing neurosurgery. The aim of this study is to compare the efficacy of using aprepitant instead of ondansetron in combination with dexamethasone and promethazine for post-operative nausea and vomiting prophylaxis. By completing this comparison study investigators will determine the most efficacious drug combination which will allow us to enhance the overall comfort and satisfaction of neurosurgical patients in the immediate postoperative period. One hundred-seventy-six (200) consecutive patients meeting the inclusion and exclusion criteria and who give written informed consent to participate in the study will be randomly assigned to one of two experimental groups using a 1:1 ratio. Patients in Group I will receive 25mg promethazine given intravenously (IV), 10mg dexamethasone given IV, 4mg ondansetron given intravenously, and a placebo pill given orally. Patients in Group II will receive 25mg promethazine given IV, 10mg dexamethasone given IV, 40mg aprepitant given orally, and an intravenous placebo. Thus all patients receive 25mg promethazine and 10mg dexamethasone. Group I will additionally receive 4mg ondansetron plus placebo PO and Group II will additionally receive 40mg aprepitant plus IV placebo. Because this is a double-blind study and because ondansetron is given intravenously whereas aprepitant is given orally, it is necessary to give patients an oral or IV placebo, depending on their group assignment for uniformity.
The purpose of this study is to down-regulate VEGF expression in esophageal cancer patients by thalidomide, so to improve their chemoradiotherapy effect. Patients with esophageal cancer receiving chemoradiotherapy were divided into different sub-group according to dynamic change of their VEGF level,and those showed increased or unchanged VEGF were added thalidomide at random. Efficacy and side effect of thalidomide combined with chemoradiotherapy were evaluated, and at the same time, activity of thalidomide on esophageal cancer and its clinical safely were assessed. Radiotherapy:Patients will be conducted CT simulation, and three-dimensional conformal radiation therapy (3DCRT) was performed. 1.8-2.0 Gy/fraction, 5 fractions a week, with a total dose of 60-72Gy will be delivered for all patients by 6-MV-X-ray of linear accelerator. Chemotherapy: Patients will be concurrently administered with irradiation every 4 weeks with PT regimen (cis-platinum of 25 mg/m2/d, d1-4; PTX(paclitaxel)of 135mg/m2/d, d1) for 4 cycles. For the first 2-cycles of chemotherapy they will be concurrently given with irradiation and the remained 2 cycles, after irradiation. Administration of thalidomide: Determine serum VEGF level of the esophageal cancer patients 3-4 weeks after the beginning of radiotherapy, those whose VEGF level, compared with that before radiotherapy, increased or unchanged will be divided into two groups: one is given thalidomide concurrent with the following chemoradiotherapy, 100mg/d at bedtime for the initial week, and if no moderate above side effect occurred 200mg/d from the next week till the end of chemoradiotherapy; the other received concurrent chemoradiotherapy only.
Endoscopic injection of autologous blood can control bleeding from gastroduodenal ulcers. To test the hypothesis that endoscopic injection of autologous blood is superior to endoscopic injection of diluted epinephrine in controlling bleeding from gastroduodenal ulcers.
To test whether intravenous albumin can decrease the rebleeding rate or shorten the duration of hospitalization in patients with peptic ulcer bleeding and hypoalbuminemia. Peptic ulcer bleeding is a common but potentially lethal disease. Recurrent bleeding is an independent risk factor for mortality. Inhibition of gastric acid secretion by intravenous proton pump inhibitor infusion can have a positive impact on the prevention of ulcer rebleeding after successful endoscopic therapy. However, the rebleeding rate can still be high in patients with comorbid illnesses even after proton pump inhibitor usage. Hypoalbuminemia has been reported to be a significant predictor of poor prognosis in patients with comorbid illnesses. Low serum albumin levels are associated with poor prognosis of wound healing and peptic ulcer bleeding; therefore, it is worthy to conduct a head-to-head comparison to validate whether administration of albumin can be helpful in improving the control of bleeding peptic ulcers, especially in patients with comorbid illnesses. The albumin level may reflect upstream pathologic processes, such as stress or co-morbidities. Albumin administration may interrupt the downstream chain of poor outcome and thus maintain a favorable homeostasis in critically ill patients, and reduce morbidity. However, the clinical benefit of controlling peptic ulcer bleeding with exogenous albumin remains uncertain, and thus administration of albumin is not widely applied. Accordingly, the investigators conducted this pilot intervention to test whether short-term exogenous albumin administration can improve the control of peptic ulcer bleeding in hypoalbuminemic patients, who are at high risk of recurrent bleeding.
Bleeding is the most avoidable cause of death in trauma patients. Up to one-third of severely injured trauma patients are found to be coagulopathic and forty percent of the mortality following severe injury is due to uncontrollable hemorrhage in the setting of coagulopathy. It has been established that early administration of fresh frozen plasma decreases mortality following severe injury, replacing lost coagulation factors, improving the coagulopathy and restoring blood volume. This study will determine if giving plasma to severely injured trauma patients during ambulance transport versus after arrival to the hospital will help reduce hemorrhage, thus decreasing both total blood product administration and mortality. Study Design: Severely injured trauma patients with a systolic blood pressure (SBP) ≤ 70 or SBP ≤ 90 with a heart rate ≥ 108 bpm at the scene will be enrolled and randomized to receive either 2 units of frozen plasma thawed in the field or normal saline (the current standard of care), as the initial resuscitation fluid. After this initial resuscitation fluid, both groups will receive the same standard of care, including packed red blood cells, additional normal saline, or plasma as needed based on laboratory and clinical evidence of coagulopathy. Blood samples and clinical information will be collected throughout the hospital stay up to 28 days after injury.
The purpose of this study is to investigate if a computerised decision-support tool used in general practice, can reduce the frequency of peptic ulcer bleeding related to the use of NSAIDs (Non-Steroidal-antiinflammatory-drug) and ASA( Acetylsalicylic acid) . On the basis of "The Danish general medical database" it is possible to develope a computerised decision-support tool, which enables the general practitioner (GP) in a "pop-up" window to get information on each patients risk-factors, when prescribing NSAID and aspirin to a patient at risk. This will give the general practitioner the oppurtunity to choose a different type of preparation or prescribe ulcer-preventive medicine at the same time. The decision-support tool will be tested in a randomized trial among general practitioners. The aim is to reduce the occurence of peptic ulcer bleeding. The expected outcome is a reduction in half of the total numbers of peptic ulcers. The background of the study is that NSAIDs and Aspirins increase the risk of peptic ulcer bleeding. On average 1-2% of patients using NSAID and Aspirin will develope gastric ulcer bleeding. But for patients with one or more risk-factors, the risk increases to 9% per 6 months. The mortality in this case is 10-15%. Approximately 3200 patients are admitted to the hospital with bleeding ulcer annually in Denmark. Danish investigations have shown that 80% of all peptic ulcer bleedings admitted to hospital are related to the use of NSAID or Aspirin.
The analyses are conducted in a previous population-based cohort study using The Health Improvement Network database in the UK (Cai et al 2009).The aims of the post hoc analyses are: To estimate the relative risk of uncomplicated symptomatic peptic ulcer (UPU) associated with use of low dose aspirin (ASA) and other anti-inflammatory drugs (NSAIDs, steroids) in the general population To estimate the dose-response and duration-response associated with use of these drugs To estimate the relative risk of UPU associated with naive/non-naive use of low dose ASA in the general population To evaluate the effect of proton pump inhibitors (PPI) (alone or in combination with anti-inflammatory drugs) on the occurrence of UPU in the general population To investigate the management of low dose ASA/oral antiplatelets after UPU Risk of uncomplicated peptic ulcer in the general population
The purpose of this randomized study to compare effect of endoscopic injection of a mixture of cyanoacrylate and lipiodol versus cyanoacrylate and lauromacrogol in gastric varices. Gastroesophageal variceal bleeding is known as one of the most frequent death causes of patients with portal hypertension. When a patient has a bleeding episode, if no further prophylactic treatments is given, it's very likely that he/she will develop another rebleeding event in the future and maybe a terminal event. Gastric varices occur in 18-70% of patients with portal hypertension, which appear to be more severe, to require more transfusion and to have a higher mortality rate than esophageal variceal bleeding, with a high rate of rebleeding(38-89%). It has been recommended to use endoscopic cyanoacrylate injection as the first line treatment for hemostasis and secondary prophylaxis for gastric varices by general consensus. However, the efficacy and prevalence of complications between mixture of cyanoacrylate + lipiodol and cyanoacrylate + lauromacrogol have not yet been explored and reported. We conducted this study to evaluate the effect of endoscopic injection of a mixture of cyanoacrylate and lipiodol versus cyanoacrylate and lauromacrogol in gastric varices.
Compare 24-hour intragastric pH and therapeutic effectiveness of proton pump inhibitor (PPI) among different administration methods: per oral (PO), intravenous (IV), and sublingual (SL). Intragastric pH and therapeutic effectiveness of PPI was compared among patients given PPI with different administration methods. 24 hour intragastric pH catheter was inserted in stomach of patients with peptic ulcer an hour prior to PPI administration in order to observe the initial change in pH. Three groups of patients were given PPI through per oral, intravenous, and sublingual administration methods. The hypothesis of this study is that sublingual administration will be faster than oral or IV administration in PPI dosing with respect to intragastric pH change and re-bleeding rate.
The most common toxicity of chemotherapy is nausea and vomiting, and appropriate management of these toxicities can help patients improve tolerance for chemotherapy. Anti-emetics including dopamine antagonist, serotonin antagonist, and substance P antagonist administered to patients according to emetogenic risk of chemotherapeutic drugs. However, patients don't always experience same nausea and vomiting for the same drugs. Therefore, it is important to determine the biomarker to predict chemotherapy-induced nausea and vomiting. Some biomarkers studies were done during the chemotherapy. However it is not definite evidence of relations between biomarkers and chemotherapy. We will hope to find any predictive biomarker of CINV. 1. Primary Objective To evaluate the role of some predictive biomarkers for chemotherapy-induced nausea and vomiting 2. Secondary Objective To evaluate the clinical characteristics related to chemotherapy-induced nausea and vomiting in Korean patients 3.

Evaluation of chemotherapy-induced nausea and vomiting - Patient's Diary consisting of the following three elements: 1. NCI-CTCAE (National cancer institute-common toxicity criteria adverse event) version 4.0 2. 100mm Visual Analog Scale (VAS) 3. Functional living index- emesis - Patients should write 'Patient's Diary' from chemotherapy day 1 to chemotherapy day 4.
This is a study comparing the effect of erythromycin or metoclopramide, 2 prokinetic drugs (Drugs which are known to speed up the emptying of the stomach or in other words to move the blood out of the stomach faster) given before endoscopy to patients with upper Gastrointestinal bleeding compared to patients who will not receive either of these medications before their endoscopy. To compare the efficacy of pre-endoscopic interventions namely erythromycin, metoclopromide vs control in improving the outcomes of endoscopy in ICU patients admitted upper GI bleeding. Specific aims: 1. Wither erythromycin, metoclopromide vs control can enable visualization of the entire gastric mucosa . 2. Wither erythromycin, metoclopromide vs control can improve the quality of stomach and duodenum visualization: using the scoring system by Fossard et al
The purpose of this study is to determine whether pharyngeal packs can reduce nausea and vomiting in patients undergoing orthognathic surgery. Post-operative nausea and vomiting (PONV) is one of the most frequent and distressing complications of anesthesia. Patients often rate that PONV is worse than postoperative pain. PONV alone is one of the leading causes for delayed discharge and unpleasant experiments. Although PONV is not always life-threatening, persistent cases can result in dehydration, esophageal rupture, aspiration and potential death. The massive ingested blood and the additional issue of an altered diet (full liquids) due to a short period of jaw immobilization may be associated with a higher prevalence of PONV after orthognathic surgeries. Although most of antiemetic drugs can help prevent PONV, they cannot preclude vomiting resulting from irritating gastrointestinal stimuli such as blood in the stomach. Pharyngeal packs are thought to prevent the ingestion and aspiration of blood, cartilage and bone fragments during oral and maxillofacial surgeries. Whether pharyngeal packs can reduce the incidence of PONV is controversial. It is reported that pharyngeal packs are recommended for the purpose of preventing PONV in nasal surgeries. However, some authors suggest that pharyngeal packs have no impact on PONV or the prevalence of PONV is doubled during routine nasal surgeries. However, the population size in these studies is relatively small and the trials have significant methodological weakness. None of these trials totally addressed the issue of the pharyngeal packs on the PONV following nasal surgeries.
Hemospray (TC-325, Cook Medical Inc, Winston-Salem, NC, USA), a new adsorptive nanopowder hemostatic agent for endoscopic treatment of high-risk bleeding peptic ulcers, provides significant ease of administration compared to the combined conventional technique of saline-adrenaline injection with mechanical clip or heater probe applications. The Hemospray powder is easily applied on ulcers at difficult endoscopic positions and ulcers with fibrotic bases, where the combined conventional technique has limited efficacy. Building up on preliminary work from small single-arm studies, the investigators aim to establish the efficacy and safety of Hemospray in treating bleeding peptic ulcers in comparison with the combined conventional technique. The investigators propose a pilot study to establish our centre's feasibility of performing a prospective, randomized, parallel group trial, which compares the efficacy of Hemospray with the combined conventional technique, in the endoscopic treatment of high-risk bleeding peptic ulcers. Patients with high-risk bleeding peptic ulcers will be treated with Hemospray to determine its initial hemostasis rate (defined as endoscopically verified cessation of bleeding for at least 5 minutes after endoscopic treatment), rebleeding rate (recurrent hemorrhage during a 4-week period following the initial hemostasis) and its safety profile.
Aim: To evaluate the feasibility and safety of a restrictive versus liberal red blood cell (RBC) transfusion policy in adult patients admitted with Acute Upper Gastrointestinal Bleeding (AUGIB) in order to inform the design of a definitive phase III randomised controlled trial. Trial overview: TRIGGER is a pragmatic trial aiming to recruit adult patients admitted with all cause AUGIB (non-variceal and variceal). The study will take place in six United Kingdon hospitals and they will be randomly allocated to a transfusion policy at the cluster level; three sites will be allocated to a restrictive transfusion policy and three to a liberal transfusion policy. Given the challenges that will be involved in early recruitment and cross-speciality care, a feasibility study is essential to determine whether a sufficient proportion of eligible patients can be recruited into the trial and that clinicians can adhere to the allocated transfusion policy. Recruitment will operate for 6 months in total. The investigators will compare recruitment rate, protocol adherence, clinical characteristics of patients recruited, exposure to RBC transfusions and the difference in Hb concentrations between the restrictive and liberal transfusion policies. The investigators will collect important clinical outcomes which the investigators anticipate being central to the phase III trial, including 28-day mortality, further bleeding rates and serious adverse events between the restrictive and liberal transfusion policies. The investigators will also collect data to enable us to plan a health economic evaluation and quality of life assessment for the phase III trial.
Upper endoscopy is performed for upper gastrointestinal bleeding (bleeding in the esophagus, stomach, or part of the duodenum) to identify and potentially treat the cause of bleeding. However, blood clots often make visualization difficult during endoscopy. The current practice is to try to wash off and suction up these blood clots with the endoscope. However, this is often not successful due to blood clots blocking the suction channel. A new device has been approved by Health Canada that attaches to the endoscope and helps prevent blockage. It is believed that this device will help doctors suck out blood clots and potentially improve visualization, identification of the cause of bleeding, and possibly health outcomes, although this has never been proven. The purpose of the this clinical trial is to test whether the device works and whether it can help patients with this type of bleeding. STUDY DESIGN: This is a randomized double blind clinical trial of the BioVac suction device versus standard endoscopy suction for UGIB. The study will be performed at London Health Sciences Center Victoria Campus and University Campus with an anticipated recruitment period of 2.5 years. STUDY POPULATION: All patients over the age of 18 admitted to hospital with a diagnosis of UGIB will be considered for recruitment. Patients already admitted to hospital with another diagnosis who develop UGIB will also be included. INTERVENTION: Patients will undergo EGD for UGIB as per standard clinical practice.

Peptic ulcer from upper endoscopy at 3 and 6 month follow up 2. Clinical of upper gastrointestinal bleeding with peptic ulcer from upper endoscopy 3. Anemia by CBC at 1,3 ,6,12 month with peptic ulcer from upper endoscopy 4. Evidence of recurrent myocardial infarction from stent thrombosis
The purpose of this prospective study is to identify risk factors which could predict poor fading of SRH or early recurrent bleeding of peptic ulcer hemorrhage after successful endoscopic hemostasis and high-dose PPI infusion. These risk factors will be the selection criteria for patients who are indicated to receive second-look endoscopy. Peptic ulcer bleeding is a common disease, and recurrent bleeding is an independent risk factor leading to mortality. The appearance of stigmata of recent hemorrhage (SRH) indicates possible recurrence of peptic ulcer bleeding, for which the likelihood decreases over the course of 3-6 days. In addition to endoscopic evidences illustrating the SRH, patients with co-morbidities have a higher risk of recurrent bleeding. Patients with co-morbidities have not only higher recurrent bleeding rates during the first 3 days but also higher delay recurrent bleeding after 3-day proton pump inhibitor (PPI) infusion than those without. More than 50% recurrent bleeding develops after 3-day PPI infusion among patients with end stage renal diseases. Although endoscopic treatment plus a 72-hour intravenous PPI infusion and followed by oral PPI has already been adopted as a standard treatment in peptic ulcer bleeding currently, several studies showed limited effectiveness of such treatment for high risk patients. The reasons may be because lesions of SRH were not completely faded after initial treatment including endoscopic hemostasis and intravenous PPI infusion. Thus, it is an important issue to improve such high recurrent bleeding risk for these patients.
Background: A second endoscopic method added to injection therapy is recommended for high-risk bleeding peptic ulcers. Many endoscopic devices have been proved as useful hemostatic instruments, whereas the hemostatic efficacy of argon plasma coagulation (APC) has not been widely investigated. Aim: This study was designed to know whether additional APC treatment could influence the hemostatic efficacy after endoscopic injection therapy in treating high-risk bleeding ulcers. Methods: From October 2010 to January 2012, eligible patients who had high-risk bleeding ulcers were admitted to our hospital. They prospectively randomly underwent either APC therapy plus distilled water injection or distilled water injection alone. Pantoprazole infusion was conducted during the fasting period after endoscopy and orally for 8 weeks to encourage ulcer healing. Episodes of rebleeding were retreated with endoscopic combination therapy. Patients who did not benefit from retreatment underwent emergency surgery or transarterial embolization (TAE). Patients and methods Study cohort Patients with acute upper gastrointestinal bleeding (AUGIB) who were admitted to Kaohsiung Veterans General Hospital between January 2011 and January 2012 were screened. Inclusion criteria were (i) over 20 years of age and (ii) patients with high-risk peptic ulcer bleeding. Acute hemorrhage from upper gastrointestine was defined as classical presentation with hematemesis, coffee-ground emesis, and/or melena. High-risk bleeding ulcers were defined as participants with stigmata of a bleeding visible vessels (eg, spurting, oozing), a non-bleeding visible vessels (NBVV) or adherent clot.4 A NBVV at endoscopy was defined as a raised red, red-blue or pale hemispheric vessel protruding from the ulcer bed, without active bleeding.
This study aimed to validate CU prediction model on mortality for patients with high risk bleeding peptic ulcers after therapeutic endoscopy. Despite advances in management of patients with bleeding peptic ulcers, mortality is still 10%. We previously reported a prediction score for ulcer bleeding related mortality developed from a local cohort. The risk factors for mortality included patients older than 70, presence of co-morbidity, more than one listed co-morbidity, hematemesis, SBP < 100 mmHg, in-hospital bleeding, rebleeding, and need for surgery. Study objective This study aimed to validate the prediction of mortality among patients with bleeding peptic ulcers from different Asian countries. Method Consecutive patients with bleeding peptic ulcers who presented to the study centers in Hong Kong, Japan and Taiwan were recruited after successful primary endoscopic hemostasis. The baseline demographics, ulcer characteristics, the predictive factors, 30 days mortality, rebleeding, hospital stay and need of surgery were recorded. The accuracy of prediction for adverse events including mortality and rebleeding with the prediction risk scoring system would be analysed.
