Object The edema associated with brain swelling after traumatic injury (TBI) has been thought to be vasogenic in origin, but the results of previous laboratory studies by authors have shown that a cellular form is mainly responsible for TBI. In this study used magnetic resonance (MR) imaging techniques identify type occurs patients Methods Diffusion-weighted MR was evaluate apparent diffusion coefficient (ADC) 44 TBI (Glasgow Coma Scale Score < 8) and eight healthy volunteers. Higher ADC...

Object The goal of this study was to demonstrate the posttraumatic neurochemical damage in normal-appearing brain and assess mitochondrial dysfunction by measuring N-acetylaspartate (NAA) levels patients with severe head injuries, using proton ( 1 H) magnetic resonance (MR) spectroscopy. Methods Semiquantitative analysis NAA relative creatine-containing compounds (Cr) choline (Cho) carried out from spectra obtained means chemical shift (CS) imaging single-voxel (SV) methods 25 traumatic...

Infection with Ebola virus (EBOV) results in a life-threatening disease, reported mortality rates between 50%-70%. The factors that determine patient survival are poorly understood; however, clinical observations indicate EBOV viremia may be associated fatal outcome. We conducted study of the kinetics Zaire patients disease (EVD) who were managed at an Treatment Centre Sierra Leone during recent West African outbreak.Data from 84 EVD (38 survivors, 46 nonsurvivors) analyzed, and was...

Ebola virus (EBOV) infection is characterized by an excessive inflammatory response, a loss of lymphocytes and general paralysis the immune system, however pathophysiological mechanisms are not fully understood. In cohort 23 fatal 21 survivors ebola disease (EVD) cases admitted to Emergency Ebola-Treatment-Center in Goderich (Freetown, Sierra Leone) during 2014 2016 EBOV epidemic Western Africa, we analyzed pathway-focused gene expression profile secreted proteins involved response levels...

Background Traumatic brain injuries (TBIs) are a common cause of morbidity and mortality in war zones. Currently, the vast majority reports on war-related TBIs concern soldiers, little is known about this condition civilians. Methods This retrospective observational study from EMERGENCY NGO hospital for civilian victims Kabul, Afghanistan. Data were gathered all adults children with admitted between June November 2021. The aims to describe epidemiology clinical patterns patients non-military...

Having determined that edema and not vascular engorgement is the major factor leading to traumatic brain swelling, objective of this study was determine which type edema, cellular or vasogenic, responsible for increased tissue water in patients with focal lesions. Severely head injured (GCS 8 less) were transported imaging suites measurement apparent diffusion coefficient (ADC) using magnetic resonance technique. Cerebral blood flow by stable Xenon method also measured regions interest....

We investigate the impact on outcome of different levels supportive treatment in Ebola virus disease (EVD). The NGO EMERGENCY delivered care sequentially at two Treatment Centres (ETC) Sierra Leone: first Lakka (fluids, symptomatic, antibiotic, antimalaria treatment, and hospital level medical care), thereafter Goderich, adding organ support only African ETC with an equipped staffed intensive unit (ETC-ICU).The primary this retrospective cohort study was in-ETC mortality. Secondarily, we...

Despite the large burden of critically ill patients in developing countries, mechanical ventilation (MV) is scarce these low-resource settings. In absence data, issues like costs and lack training are often felt to outweigh benefits potential MV implementation such places. We aimed investigate impact feasibility a surgical ICU West Africa.

Pregnancy and childbirth on anticoagulants after mechanical heart valve replacement present a high risk of complications for both mother baby. On top pregnancy worsening the mother's cardiac function, anticoagulant therapy itself is crucial problem. A safe effective anticoagulation regimen fetus not possible. The most drugs preventing thrombosis are VKAs, whose dosage needs to be adjusted with frequent INR checks. Moreover, VKAs can have embryopathic teratogenic action. Patients in follow-up...

Abstract The annual incidence of blocked mechanical valvular prosthesis (BMVP) is 0.3–5.7%. 78% cases are due to thrombosis and development pannus the second more frequent etiology. risk higher for mitral prosthesis, during 1st year after valve replacement, poor INR trend. TEE gold standard diagnoses, but it seldom required if adequate TTE cine–fluoroscopy performed. As therapy, redo surgery recommended in case NYHA III–IV patients or presence big thrombi: contraindicated too high–risk,...
