To the Investigators' knowledge, TXA has not been studied in the setting of reverse total shoulder arthroplasty. We propose a double-blinded, randomized, controlled trial comparing perioperative administration of TXA to placebo in the setting of RTSA. The purpose of this study is to examine the efficacy of TXA in reducing overall blood loss and transfusion rates in patients undergoing reverse total shoulder arthroplasty.
Cerebral small vessel disease (cSVD) encompasses all pathological processes that affect the small vessels of the brain. On brain-MRI cSVD is characterized by structural brain abnormalities such as white matter lesions (WMLs). Clinically, cSVD is related to acute syndromes as lacunar stroke but also to more chronic health problems such as cognitive decline. Recent literature suggests that a disrupted blood brain barrier (BBB), leading to elevated BBB permeability, may play a pivotal role in the aetiology of cSVD and lacunar stroke. The BBB is a complex system of neuronal, glial and vascular cells which main function is to shield the brain from toxic components and regulate the homeostasis. Elucidating the role of the BBB may have far reaching consequences for the treatment of cSVD patients and the reduction of recurrence rate of the disease. This could lead to a better quality of life among cSVD patients and reduce the economic burden on society. Currently the exact contribution and extent of a possibly defective BBB in cSVD remains largely unclear, due to the lack of a reliable method to accurately quantify the BBB permeability in cSVD patients. As a result, the current treatment consists of treating the cardiovascular risk factors, often with poor results. Quantification of the BBB permeability provides an objective measure of the integrity of the BBB and as such aids the study of the role of the BBB. The aim of this study is to realize a clinically applicable MRI-method to quantify the BBB permeability. Moreover, the method can be used to study the involvement of BBB disruption in other neuropathologies including Alzheimer's disease, vascular dementia, hypertension and diabetes. Primary Study Objective: To realize a clinically applicable quantification of BBB permeability using DCE-MRI by determining the reproducibility of the DCE-MRI method Secondary Study Objective: To achieve the shortest scan duration without compromising the reliability of the BBB permeability quantification. Hypotheses: 1. Using an optimized DCE-MRI method to quantify the BBB permeability, the BBB permeability can be reliably determined in cSVD patients. 2. The scan duration can be shortened without compromising the reliability of the BBB permeability quantification.
The investigators have developed a system based on a pulse oximeter, a tablet, and an algorithm running on the tablet that analyzes the pulse oximeter waveform. The algorithm that runs on this system should be able to accurately keep track of blood loss during blood donation. The investigators will compare the algorithm with the blood loss tracked by a device called a flow meter. The algorithm that runs on this system should be able to accurately keep track of stroke volume changes. The investigators will compare the algorithm with the stroke volume changes tracked by a device called a CCNexfin. The algorithm that runs on this system should work whether it's in place for the whole blood donation, or if it's placed after the blood donation has started. The investigators will use two pulse oximeters for the system on each hand and compare one that is used for the whole blood donation versus one that is not used for the whole blood donation.
Subarachnoidal hemorrhage (SAH) is a cause of long-term disability and death. Annually about 1000 people in Finland suffer from SAH, their average age being under 50 years. SAH has a mortality rate of 12 % acutely and 40 % of patients die within a month from admission to hospital. In addition, 30 % of the surviving patients remain with neurological deficits. Most survivors of the primary insult suffer from secondary injury during the first 2-3 weeks from the insult. Despite the advances in neurosurgical and -radiological techniques and intensive care, the mortality and morbidity rates in SAH have not changed in recent years. There is still only limited understanding of the mechanisms of secondary insults causing brain injury after SAH. In this study the investigators are aiming to clarify the timescale and mechanisms contributing to the secondary insults. The investigators also explore usability of novel biomarkers to guide treatment of the patients suffering from SAH.
Endoscopic high-frequency soft coagulation is available for the management of bleeding or nonbleeding visible vessels during endoscopic submucosal dissection. However, its efficacy on peptic ulcer bleeding has not been elucidated so far. The aim of this study was to evaluate the efficacy of hemostasis with soft coagulation using hemostatic forceps by comparing it with argon plasma coagulation (APC) in a prospective, randomized trial.
The purpose of the present study is the clinical assessment of the efficacy of preincisional peritonsillar infiltration of dexmedetomidine on postoperative pain relief in children undergoing adenotonsillectomy.
ASA is the most commonly drug used worldwide for prevention of cardiovascular diseases. However, ASA is increasingly recognized as a culprit for small bowel bleeding. Small bowel bleeding is notoriously difficult to diagnose because it is beyond the reach of conventional endoscopy. The advent of wireless, video capsule endoscopy has revolutionized the visualization of small bowel. Capsule endoscopy is a pill that contains a tiny camera for capturing pictures of the small bowel after being swallowed. Currently, capsule endoscopy is a recommended noninvasive approach of identifying the source of small bowel bleeding. Management of ASA-associated small bowel bleeding is a major clinical challenge since there is not a single effective treatment for small bowel ulcer, and continuation of ASA increases the risk of recurrent small bowel bleeding. However, discontinuation of ASA exposes patients to thrombotic complications. Suppression of prostaglandin synthesis is an important mechanism of ASA-induced small injury. Consistent with this theory, preliminary data from a case series showed that misoprostol, a prostaglandin analog, healed small bowel ulcers in ASA users. However, the efficacy of misoprostol in healing ASA-associated small bowel ulcers has not yet been confirmed by prospective randomized trials. This double-blind clinical trial tests the hypothesis that misoprostol can heal small bowel ulcers in Aspirin users complicated by small bowel bleeding.
