Filter by:Vertebra is one of the most common site of metastatic disease, which may cause severe pain or neurological deficit. Debulking surgery usually has better local control and survival benefit as compared with decompression or radiotherapy. However, debulking surgery often accompany with massive blood loss, which may cause hemorrhagic shock or death. The major bleeding point during operation including tumor parenchyma, arteries that are difficult to ligate, and epidural venous plexus. Vascularity of tumor parenchyma had been associated with increased intraoperative blood loss, on the other hand, there is a lack in the literature regarding to evaluation of the size, flow and pressure of epidural venous plexus, and their changes after embolization.
Our study aims to evaluate the role of depression in blood pressure control in ambulatory hypertensive patients.
The objective of this study is to evaluate the impact of an evidence-based mental health intervention (Common Elements Treatment Approach) on medication adherence, behavioral improvement and clinical outcomesamong adults taking medication for hypertension, diabetes and epilepsy using a two-arm randomized wait-list controlled trial among adult refugees in Mae La camp, Thailand.
To evaluate safety and the ocular hypotensive effect of STN1012600 ophthalmic solution 0.002% alone or in combination with Timolol ophthalmic solution 0.5% for 52 weeks in subjects with open angle glaucoma or ocular hypertension.
Patients with established liver cirrhosis, or end-stage liver disease (ESLD), are at high risk of developing liver cancer (hepatic carcinoma; HCC), portal hypertension, and sarcopenia, all which lead to significant morbidity and mortality. In this patient group the annual incidence of HCC is c. 2-8% and these patients are therefore included in ultrasound HCC screening programs every 6 months. In this study, the investigators are aiming to assess sarcopenia, clinically significant portal hypertension (CSPH), and HCC with a single short magnetic resonance (MR) examination. A neck-to-knee MRI-examination will be acquired to derive body composition profile (BCP) measurements including visceral and abdominal subcutaneous adipose tissue (VAT and ASAT), thigh fat free muscle volume (FFMV) and muscle fat infiltration (MFI), as well as liver fat (PDFF), spleen volume, and liver stiffness. Images will be further processed by AMRA Medical AB. AMRA's solution includes FFMV in the context of virtual control groups (VCG; using AMRA's vast database) and MFI. Furthermore, the spleen volume will be used to monitor the development of portal hypertension and explored together with other BCP variables in relation to hepatic decompensation events. HCC screening will be performed using so-called abbreviated MRI (AMRI), which consists of time series of contrast-enhanced T1-weighted images. The AMRI images will be read by an experienced radiologist. In the literature the sensitivity of AMRI to detect HCC is above 80%, with a specificity of c. 95%, compared to ultrasound sensitivity of 60%. In treating ESLD there is a desire of physicians to be able to predict future decompensation events in order to initiate treatment to prolong survival. Moreover, the ability to assess processes of sarcopenia in the patient would be highly valuable for clinical practice due its severe clinical impact. Finally, ultrasound-based HCC screening has poor diagnostic performance and a MR-based screening approach would significantly improve treatment outcome as more treatable and earlier HCC may be identified.
The overarching goal of our proposal is to reduce disparities in perinatal cardiovascular disease risk factors among Black women utilizing a community-driven, social ecological framework.
The purpose of this study is to investigate the effect of sacubitril/valsartan on cardiac function assessed by cardiac magnetic resonance (CMR) in hypertensive patients stratified by BMI.
The aim of the study is to determine whether conducting a randomized placebo-controlled clinical trial is feasible, safe for the patient and whether the treatment is well tolerated in patients with idiopathic pulmonary arterial hypertension.
This is a randomized clinical trial intended to identify the optimal strategy of blood pressure management in rural South Africa using Community Health Workers (CHWs) in conjunction with in-home BP monitoring among adults.
This study aims to learn about the effects of continuous positive airway pressure (CPAP) on people with autonomic failure and high blood pressure when lying down (supine hypertension) to determine if it can be used to treat their high blood pressure during the night. CPAP (a widely used treatment for sleep apnea) involves using a machine that blows air into a tube connected to a mask covering the nose, or nose and mouth, to apply a low air pressure in the airways. The study includes 3-5 days spent in the Vanderbilt Clinical Research Center (CRC): at least one day of screening tests, followed by up to 3 study days. Subjects may be able to participate in daytime and/or overnight studies. The Daytime study consists of 2 study days: one with active CPAP and one with sham CPAP applied for up to 2 hours. The Overnight study consists of 3 study nights: one with active CPAP, one with sham CPAP, both applied for up to 9 hours and one night sleeping with the bed tilted head-up.
