Active clinical trials for "Hemorrhage"

This study aims to assess the 6- and 12-month venous thromboembolism (VTE) and bleeding incidence from the start of cancer diagnosis in a retrospective cohort of patients with esophageal cancer. Additionally, the predictive value of the Khorana score and several other VTE and bleeding prediction scores and risk factors will be evaluated.

Angiogenesis is inherently associated to bone formation and healing. During implant osseointegration, a successive and successful angiogenic processes has to occur to promote bone formation. In 1969, Branemark et al. demonstrated that direct contact between bone and titanium implant surface was possible, defining osseointegration as "the direct, structural, and functional contact between live bone and the surface of a functionally loaded implant". Consequently, the need of an empirical measurement appeared. With the introduction of resonance frequency analysis (RFA), it is now possible to measure the degree of implant stability at any time during the course of implant treatment and loading. In this way, changes in implant stability can be monitored over the time and it is likely possible to find implants at risk of failure before they become loose. The rationale of this study is to analyse how important a good vascularization is for the future bone formation around dental implants.

Upper gastrointestinal (GI) bleeding is defined as patients who either presented with hematemesis or presented with melena along with evidence of hemodynamic compromise. These patients have risk of aspiration of blood along with gastric content. The mortality rate can be 15% to 20% in the cases with variceal bleeding. From a practical standpoint, it is widely accepted that the best way to secure an airway during upper GI bleeding is prophylactic endotracheal intubation (PEI). The aim of this study is to determine the incidence of complications among critically ill patients with upper GI bleeding and received urgent endoscopy.

The aim of the study is to look if Quick Sequential Organ Failure Assessment Score score in detecting a eary Sepsis is afflicted by neurosurgical disorders

The investigators aim to investigate and understand the circulating miRNA profiles after acute aneurysmal subarachnoid haemorrhage and underlying pathological significance.

Following endoscopic therapy of variceal bleeding, the issue of when to refeed these patients has rarely been investigated. This may imply that feeding is generally regarded as a negligible factor in the management of bleeding varices. On the other hand, it is usually believed that systematic fasting is required in case of patients with upper gastrointestinal bleeding. Some researchers in their studies demonstrated that immediate refeeding has similar outcomes to delayed refeeding among patients with low risk of nonvariceal bleeding. The situation of variceal bleeding is quite different from that of peptic ulcer bleeding as demonstrated by studies of other researchers who made a review on feeding of patients with upper gastrointestinal bleeding, and recommended that feeding should be delayed for at least 48 hours after endoscopic therapy because early refeeding may cause a shift in blood flow to the splanchnic circulation, which in turn could lead to an increase in pressure and an increased risk of rebleeding from the varices. The other important reason of delay in feeding may be ascribed to the fear of occurrence of early rebleeding induced by refeeding. In addition, repeated endoscopic examination and therapy may be required in patients with very early rebleeding. The decision to delay feeding is usually based on clinicians 'experience or experts' opinion rather than evidence based. That is why we planned this study.

The investigators hope to answer the question, "does ketorolac increase the risk of hematoma after reduction mammoplasty?" using a case-control study. All patients who developed a hematoma post reduction mammoplasty (cases) at our institution, and match these with women who had an uncomplicated reduction mammoplasty (controls), and then compare frequency of ketorolac exposure between these two groups as the primary outcome. If ketorolac increases the risk of hematoma, one should expect cases to have been exposed to ketorolac more frequently than controls. Based on previously existing literature, the investigators hypothesize that cases and controls will not differ in their ketorolac exposure, that is, ketorolac does not increase the risk of hematoma.

A rare case of disastrous delayed postpartum hemorrhage after three days of shenghua decoction treatment.

The aim of this study is to assess the value of adding 3D power Doppler (as a diagnostic technique) to gray scale technique in the antenatal diagnosis of morbidly adherent placenta as well as predict the surgical outcome regarding the type of surgery and the intra operative morbidities.

More than 80% of patients with upper gastrointestinal bleeding (UGIB) are hospitalized after their visit to the emergency department (ED). However, some of these hospitalizations do not seem justified. Several clinical scores have been developed to classify patients according to their risk of death or need for therapeutic intervention. The aims of this study are: to describe the characteristics of patients hospitalized for UGIB after their visit to the ED to assess the predictive factors of hospital intervention or death to assess the accuracy of existing prognostic scores to classify patients according their risk of death or need for therapeutic intervention (external validation) and to identify low-risk patients not requiring intervention. Depending on the results, a new score could be derived to identify patients at low risk for intervention or death.
