Filter by:Worldwide there is a high prevalence of morbid obesity with a progressive increase in incidence in recent years, causing serious consequences for the health services. Approximately 12% of the world population is obese and Brazil is in 77º without world ranking of countries in cases of obesity. In this context, bariatric surgery appears as an effective method of treating refractory obesity. Support of high fractions of oxygen administered during anesthesia is produced, it accepts the use of Positive Positive Positive Pressure (PEEP) through the Alveolar Recruitment Maneuver (ARM), which has been used allowing small fractions inspired by oxygen, which reduces intra-and postoperative atelectasis and optimizes gas exchange during anesthesia. In order to better monitor ventilatory mechanics, Electrical Impedance Tomography (EIT) appears as a cheap imaging method when compared to a non-invasive magnetic resonance imaging (CT) or MRI, with no side effects and recent studies shown in its life as pneumothorax , MRA monitoring, collapse detection, and PEEP titration. The aim of this study is to evaluate the impact of ARM and its repercussions on lung function and respiratory mechanics. This is a randomized controlled clinical trial with patients undergoing videolaparoscopic gastroplasty surgery, of both sexes. Patients were randomly assigned to Control Group and Experimental Group. Patient evaluation is performed without before, during and postoperative, through a pulmonary function test and EIT.
Number of patients with unsatisfactory pain relief defined as average visual analog scale (VAS) more than 5 with or without requirement of IVPCA for pain relief during the first 48 hours postoperative period will be compared between the two groups and form the primary outcome for the study. Postoperative pain intensity will be measured by Visual Analog Scale (VAS) with 0- being no pain and 10-being maximum pain and the analgesic efficacy in both groups will also be evaluated by the amount of total narcotic consumption (measured with IV morphine equivalent doses of analgesics used to provide pain relief).
This is a single-institution, prospective phase II trial with an initial safety run-in to evaluate the efficacy and safety of neoadjuvant pembrolizumab combined with chemoradiotherapy and adjuvant pembrolizumab in patients with locally advanced esophageal and gastric cancers (EGC). Chemoradiation therapy (45Gy in 25 fractions with concurrent, weekly carboplatin [AUC 2] and paclitaxel [50mg/m2 of BSA]) with three cycles of pembrolizumab will be administered as neoadjuvant therapy. These patients will also receive three cycles of adjuvant pembrolizumab after surgical resection
A new Magnetic-controlled Capsule Endoscopy (MCE) was developed by ANKON and got SFDA's approval in China in 2013. It has recently been evaluated to compare the diagnostic accuracy of MCE with that of standard gastroscopy for gastric diseases in 70 patients with encouraging results (In Press). To further testify the diagnostic accuracy of MCE for both the diffuse and focal diseases in stomach, we performed this single-blinded multi-center prospective study compared MCE with gastroscopy in patients with gastric symptoms and indication for upper GI Endoscopy.
Rationale: The construction of esophageal anastomoses is associated with considerable risk at postoperative anastomotic leakage. Application of TachoSil®, a tissue sealant with human fibrinogen and thrombin, can improve strength of the esophageal anastomosis and potentially prevent anastomotic leakage. Objective: Evaluation of feasibility and safety of TachoSil® application on esophageal anastomoses. Study design: Non-randomized, non-blinded, single-center intervention study. Study population: Patients, 18-80 years old, undergoing an elective total gastrectomy with an esophago-jejunostomy or esophagectomy with a planned esophagogastric anastomosis will be enrolled. A total number of 15 patients will be included in the study. Intervention: Gastric or esophageal resection will be executed according to the common procedures used in the UMC Utrecht. After construction of the esophageal anastomosis, all enrolled participants will receive a TachoSil® patch, which will be applied on the esophageal anastomosis intra-operatively. Hence, TachoSil® is used as an add-on therapy. TachoSil® will be degraded enzymatically in a period of approximately 24 weeks after application. Main study parameters/endpoints: The primary endpoint is feasibility, which is assessed by evaluation of adherence of the patch. A time-action analysis of the application of the Tachosil patch will be performed. Nature and extent of the burden associated with participation: The burden for the patient is minimal. The total surgical procedure will be prolonged with 10-15 minutes. Postoperative care and outpatient visits do not differ from regular protocol. TachoSil® is approved and registered for supportive treatment in surgery for improvement of haemostasis and to promote tissue sealing by the European Commission.
Gut of newborn preterm is sterile, immediately by the mother and the surrounding environment from microbial colonization. As the effects of diet, intestinal flora is rapidly changed. Preterm children significantly delay in the establishment of normal flora,during hospitalization because of no breastfeeding, use of antibiotics, enteral feeding delay, combat disease and other factors. In this study, hospitalized preterm children for the study, the prospective randomized double-blind controlled study, to find oral intestinal bifidobacteria and lactobacilli and bifidobacteria subspecies composition and distribution, and further show intestinal bacteria in premature children case group.
The purpose of this study is to compare the efficacy between 1-day high dose PPI-based triple therapy vs. 10-day sequential therapy for Helicobacter pylori eradication in functional dyspepsia patients.
This is a prospective, open-label, single-arm, non-randomized, multi-center, phase II proof of concept (PoC) study with a two-stage design and Bayesian interim monitoring to evaluate efficacy and safety of single agent TKI258 in adult patients with scirrhous gastric carcinoma (SGC) that have progressed after one or two prior systemic treatments.
The investigators study the feasibility of a novel method in oncology based on breath analysis with a nanosensors array for identifying gastric diseases. Alveolar exhaled breath samples collected from volunteers referred for upper endoscopy or surgery are analyzed using a custom-designed array of chemical nanosensors based on organically functionalized gold nanoparticles and carbon nanotubes. Predictive models are built employing discriminant factor analysis (DFA) pattern recognition method. Classification accuracy, sensitivity and specificity are determined using leave-one-out cross-validation or an independent blind test set. The chemical composition of the breath samples is studied using gas chromatography coupled with mass spectrometry (GC-MS). A pilot study is conducted first (enlistment of 160 subjects at the Department of Oncology, The First Affiliated Hospital of Anhui Medical University, The First Affiliated Hospital of Anhui Medical University, Hefei, Anhui, China.) The pilot study is followed by a large-scale clinical trial to confirm the preliminary results of the Chinese pilot study (enlistment of 800 subjects at the Digestive Diseases Centre GASTRO, Riga East University Hospital, 6 Linezera iela, LV1006 Riga, Latvia). 25% of the samples are used as independent blind test set. The samples are blinded by the medical team and are not disclosed until prediction of blind sample identity is complete. To further prove the diagnosis of GC from exhaled breath and seek the interrelationship among Breathomics, metabolomics and transcriptomics, saliva samples from about 200 patients are collected from volunteers referred for upper endoscopy or surgery are analyzed using Ultra-high-performance liquid chromatography-mass spectrometry (UHPLC-MS). Simultaneously, RNA sequencing are preformed on gastric cancer tissue samples and paracancerous tissue samples collected from same group of volunteers. The data of salivary metabonomics and transcriptomics were integrated and analyzed on the on Kyoto Encyclopedia of Genes and Genomes to confirm the diagnostic validity of salivary metabonomics.
This feasibility trial will evaluate the ability of the SuMO Tissue Access and Resection System (Apollo Endosurgery, Austin, Texas). The SuMO System utilizes balloons to create a submucosal pocket and electrosurgical cutting device to resect the mucosa. The SuMO elevates the tissue from the underlying muscularis using a balloon to distend the submucosa, similar to what is currently performed with injectable saline in a standard EMR. After dissection of the lesion, a separate cutting device will be utilized to resect the tissue by cutting around the border of the targeted tissue. If needed, a standard loop snare will be used to complete the mucosal resection.
