Filter by:The purpose of this study is to determine whether Valacyclovir treatment, administered during pregnancy after proven primary maternal Cytomegalovirus (CMV) infection, reduces fetal transmission rates and prevents fetal injury in cases of fetal infection.
Environmental cleanliness As antimicrobial resistance is a major and overall deteriorating public health problem international cooperation is necessary. Continued progress is needed to implement and improve programmes for the prevention and control of antimicrobial resistance and HAIs. Environmental cleanliness might be one of the most important initiatives to reduce HAIs. Hospital surfaces are heavily contaminated with bacteria with the highest numbers on surfaces closest to the patients. Bed rails, nurse call buttons, curtains, towel dispensers, door handles, sinks, floors, clinical information stations, medical devices, stethoscopes, staff toilets etc. Actually, general hospital wards and Intensive Care Units are loaded with an abundance of potential pathogens 8,9,10. Surviving days, weeks or even months in the environment 11. Colonizing patients with bacteria from the hospital environment and getting HAIs or even die. As most ventilator-associated pneumonias (VAPs) are the result of nosocomial microorganisms the environment plays an important role in the acquisition of pathogenic bacteria by contaminating health care workers hands and equipment 12,13. Furthermore, ICUs and wards struggle with colonized patients with ESBL-bacteria from sinks eventually leading to dead or outbreaks of group A streptococcus infections from contaminated curtains 14,15. As key healthcare-associated pathogens have the capacity to persist for weeks to months on hospital surfaces indirect transmission is a serious threat, especially as antimicrobial resistance increases. Hospitalization in a room in which the previous patient had been colonized or infected with nosocomial pathogens (e.g. MRSA, VRE, multidrug-resistant Acinetobacter, Pseudomonas or C. difficile) has been shown to be a risk factor for colonization of infection with the same pathogen for the next patient16. Furthermore, the most important risk factor for hand and glove contamination of healthcare workers with multidrug-resistant bacteria has been demonstrated to be positive environmental cultures 17. To decrease the frequency and level of contamination of environmental surfaces the Centre for Disease Control and Prevention recommends routine disinfection of medical equipment and environmental surfaces to prevent the spread of potential pathogens through the hospital ward or ICU 18. Improved room cleaning has shown to decrease the risk for MRSA, VRE and C. difficile acquisition. Unfortunately, environmental cleaning is frequently inadequate. Less than 50% of hospital room surfaces are adequately cleaned and disinfected even by environmental services personnel. Environmental services personnel have low wages, are under time pressure to clean rooms quickly with high turn-over rates of patients. Novel materials and cleaning technologies have been developed as ultraviolet germicidal irradiation (UVGI) or hydrogen peroxide vapor (HPV). However, both technologies are expensive and can just be used for terminal cleaning and not during routine daily care 16. Self-disinfecting surfaces may overcome these problems. Once applied antimicrobial surfaces will continuously reduce the bioburden of nosocomial pathogens preventing transmission and decrease HAIs. MVX One of these self-disinfecting products is MVX. MVX contains titanium dioxide which by the use of nanotechnology is now available for use in the health sector. Working as a photocatalyticum it generates, in the presence of light, hydroxy radicals and oxygen radicals for at least five years after coating hospital surfaces (durability test TUV Rheinland). Laboratory tests show that MVX is effective in killing bacteria, viruses and fungi (see attachment 1 for summary test results). The positive results reported on the effects of MVX from laboratory evaluations still have to be confirmed in the clinical setting. After getting the CE-marking Gelderse Vallei Hospital in Ede, the Netherlands, will be the first hospital in Europe to study the efficacy of MVX in the Intensive Care Unit (ICU).
The study will explore the ability of negative pressure wound therapy (Prevena dressing) to reduce post operative superficial surgical site infection rate in elective colorectal surgery. Half of the participants will receive Prevena dressing on closed incision immediately after the operation while other half will receive conventional surgical dressing.
The primary objectives of this study are to evaluate the efficacy, safety, and tolerability of treatment with sofosbuvir/velpatasvir (SOF/VEL) in participants with chronic genotype 1, 2, 4, 6 or indeterminate HCV infection who received placebo in the Gilead-sponsored study GS-US-342-1138.
To evaluate the safety and efficacy for treatment of persistent CMV infection in hematopoietic cell transplant (HCT) recipients.
Death in Ataxia telangiectasia (A-T) is usually due to cancer or chronic lung failure around 20 years of age. Despite low lymphocyte counts (CD3, CD4, CD8 and CD19), IgA and IgG subclass deficiency opportunistic and acute severe respiratory infections are rare. The prevailing wisdom is that an immunoglobulin replacement therapy is not necessary in most of the patients. However no placebo controlled trials have been performed so far. The aim of this trial was to investigate the prevalence of mild and severe respiratory infections and / or chronic cough in classical A-T patients compared to healthy controls.
Background: - There are more emerging infectious diseases recently. Some could affect many people. Some like Severe Acute Respiratory Syndrome (SARS) or Middle East Respiratory Syndrome (MERS) are caused by new germs. Sometimes known germs suddenly infect new and large areas, like Ebola. Many of these diseases don t have good treatments available. Researchers may be able to develop a treatment by using antibodies against these infections. Objective: - To collect antibodies from people with high levels of antibodies to the diseases being studied. Eligibility: - Ages 18-70 years old who weigh at least 110 pounds. They may have been infected with or vaccinated for one of the new infections researchers are studying. Design: - Participants will be screened with medical history and blood tests. Researchers will determine if the participant can have apheresis. - Participants will have apheresis. First, they will be interviewed. Then, a needle will be placed in a vein. Blood will be drawn, and a machine will separate the blood cells from the antibodies and protein. The blood cells will then be returned to the participant through another vein. It takes about 60 minutes for the actual collection. - Participants will be asked to have the procedure at least 3 times. They can participate in up to 20 sessions total as part of this study. There must be at least 7 days between sessions.
Chronic fatigue syndrome (CFS) is characterized by unexplained, disabling and long lasting fatigue, as well as pain, impaired memory, sleep difficulties and other symptoms. Epstein-Barr virus (EBV) infection might precipitate CFS. In this study, 200 adolescents undergoing acute EBV infection will be followed prospectively, and also compared with a group of healthy controls. The aim is twofold: - To identify factors that predispose to chronic fatigue among adolescents with acute EBV infection - To compare pathophysiological features of patients with acute EBV infection with a group of healthy controls. Possible risk factors for chronic fatigue 6 months after EBV-infection includes: - Severity of the initial infection - Immune responses characteristics - Characteristics of the neuroendocrine stress response - Cognitive functioning - Emotional disturbances - Genetics/ epigenetics of candidate genes - Certain personality traits - Critical life events
It is hypothesized that implementing plasma CrAg screening in clinics providing routine HIV care will enable identification of Vietnamese adult patients with advanced HIV (CD4 ≤100 cells/μL) who have early cryptococcal disease, enable prompt preemptive treatment with high-dose fluconazole, and improve survival.
Purposes of this study will be as follows: 1. To design a prospective, randomized, and open-labeled study to investigate the effect and the side effect of MPD in combination with conventional antibiotics to affect clinical course, outcome, and medical expenses. 2. To compare level of the urinary and serum cytokines before and after received MPD for the following sub-aim: I. To determine the population who is benefit from MPD to reduce the severity of clinical course and subsequent renal scarring. II. To understand the mechanism by which the MPD could shorten the clinical course and reduce the renal scarring.
