Background/Aim:

Acute upper gastrointestinal hemorrhage (AUGIH) is a life-threatening emergency that results in high morbidity and mortality. The mortality rate varies between 4% and 14%. The aim of the study was to determine the clinical outcome of AUGIH among patients admitted to a government hospital in Egypt.

Patients and Methods:

This was a cross-sectional hospital-based study performed in 1000 patients presenting with AUGIH over a 7-year period between January 2004 and January 2011.

Results:

One thousand patients were analyzed. Fifty-four percent were male. Mean age was 52 ± 17 years. Eighty-eight percent were emergency admissions and 12% were inpatients at the time of bleeding. At presentation 68% had major comorbidity and 50% had liver disease. Seven hundred and twenty-four patients (72%) underwent endoscopy. Bleeding varices accounted for 31% of AUGIH and peptic ulcer 28%. Two hundred and thirty-two patients had endoscopically diagnosed bleeding varices or peptic ulcer with a visible vessel or active bleeding. These received endoscopic therapy. Initial hemostasis was achieved in 207 (89%). Thirteen patients (6%) had therapy at a subsequent endoscopy for further bleeding. Surgery was performed on 9 patients (0.9%) with AUGIH. Complications were reported in 70 patients (7%) mainly liver failure (4%). Six hundred and eighty-four patients (68%) were discharged improved, 162 (16%) left hospital without a diagnosis and 4 (0.4%) were referred to another facility. The overall mortality was 15%. Mortality was 24% in patients ≥60 years, 37% among inpatients, and 21% in those who had a major comorbidity. Mortality was 22% in patients who had liver disease and 9% in variceal bleeding.

Conclusion:

The most common cause of AUGIH was variceal in origin. Endoscopic therapy was successful in most cases. Mortality after AUGIH was particularly high among elderly patients, inpatients, and patients who had a major comorbidity, liver disease, and variceal bleeding.  相似文献

Transcatheter aortic valve replacement (TAVR) has proven to be a viable tool for the high-surgical-risk population with severe aortic valve stenosis. Vascular access complications are not uncommon with TAVR and may increase early and late mortality. Avoiding these serious complications is the goal. With experience and careful screening, we are now able to risk-stratify patients who may be at increased risk of vascular complications. While the traditional iliofemoral access site remains the most common for TAVR, alternate access sites that have proven to be viable and safe alternatives include the transapical, direct-aortic, and subclavian techniques. TAVR teams should be familiar and comfortable with these approaches as each of them has its own advantages and weaknesses. The best option is usually one in which the procedure is tailored to the patient. The present review examines our current access planning and strategies for TAVR.  相似文献

Recent studies suggest that patients’ elevated blood pressure (BP) readings in the Emergency Department (ED) may be due to hypertension (HTN) rather than pain and anxiety. Identifying BP patterns suggestive of HTN in the ED presents an opportunity for referral. The purpose of this prospective cohort study was to assess the feasibility of referral of ED patients with elevated BP readings suggestive of HTN. Adults with elevated BP suggestive of HTN and no history of HTN were tracked as to referral status using an actively monitored ED referral system. Patients referred to a community clinic network were tracked regarding clinic visits, subsequent BP, and diagnosis of HTN. Of 662 patients with elevated BP in the ED at triage, 197 (29.8%) had a pattern of blood pressure readings that were suggestive of HTN. Of these, 63 (32.0%) were referred to in-network clinics, 5 (2.5%) were referred out of network, and 129 (65.5%) were not referred. Of the 63 referred to network clinics, 17 (27.0%) kept their appointments and of those, 5 (29.4%) were diagnosed with HTN. Elevated BP was not mentioned in any ED physician referral notes as a reason for referral and the number of appointments kept among patients who were referred was low. Referral to outpatient clinics based on BP levels suggestive of HTN may not be feasible despite active referral systems.  相似文献

Background and Objective

Double sequential external defibrillation (DSED) and vector-change defibrillation (VCD) have been suggested to enhance clinical outcomes for patients with ventricular fibrillation (VF) refractory of standard defibrillation (SD). Therefore, this network meta-analysis aims to evaluate the comparative efficacy of DSED, VCD, and SD for refractory VF.

Methods

A systematic review and network meta-analysis synthesizing randomized controlled trials (RCTs) and comparative observational studies retrieved from PubMed, EMBASE, WOS, SCOPUS, and Cochrane through November 15th, 2022. R software netmeta and netrank package (R version 4.2.0) and meta-insight software were used to pool dichotomous outcomes using odds ratio (OR) presented with the corresponding confidence interval (CI). Our protocol was prospectively published in PROSPERO with ID: CRD42022378533 .

Results

We included seven studies with a total of 1632 participants. DSED was similar to SD in survival to hospital discharge (OR: 1.14 with 95% CI [0.55, 2.83]), favorable neurological outcome (modified Rankin scale ≤2 or cerebral performance category ≤2) (OR: 1.35 with 95% CI [0.46, 3.99]), and return of spontaneous circulation (ROSC) (OR: 0.81 with 95% CI [0.43; 1.5]). In addition, VCD was similar to SD in survival to hospital discharge (OR: 1.12 with 95% CI [0.27, 4.57]), favorable neurological outcome (OR: 1.01 with 95% CI [0.18, 5.75]), and ROSC (OR: 0.88 with 95% CI [0.24; 3.15]).

Conclusion

Double sequential external defibrillation and VCD were not associated with enhanced outcomes in patients with refractory VF out-of-hospital cardiac arrest, compared to SD. However, the current evidence is still inconclusive, warranting further large-scale RCTs.  相似文献

Despite tremendous success of growth factor therapy in animal models, clinical trials have demonstrated minimal success. Vascular endothelial growth factors are perhaps the most potent inducers of angiogenesis in these animal models. This review outlines the biology of vascular endothelial growth factors in the context of myocardial angiogenesis with an emphasis on its effects on the endothelium. It also provides an overview of delivery strategies and summarises the preclinical and clinical evidence relating to exogenous growth factor delivery for myocardial angiogenesis with an emphasis on the key future challenges.  相似文献
