Filter by:Surgical site infections (SSI) are costly complications that may cause significant morbidity and increase the cost of care, particularly in colorectal surgery. Microbial sealants (MS) are a new class of wound barriers aimed at decreasing SSI, however there is only evidence of benefit in clean Class 1 procedures. Based on its success in Class 1 procedures, we hypothesized that a microbial sealant could reduce the rate of SSI by half for clean contaminated colorectal procedures (Class 2).
Rationale: Infections are an important worldwide cause of death, both in elderly and young children. Therefore, support of immunity could help to reduce the incidence of infections. To screen the potential of specific foods or food ingredients to support immunity, oral vaccination can serve as a model. In this study, oral cholera vaccination will be applied in human adult volunteers, and used as a model to study the support of the immune response by raw milk. Objective: To investigate whether raw milk is able to enhance the immune response as induced by oral cholera vaccination. Study design: The study is designed as a single-blind randomized controlled trial of 4 weeks. Study population: Healthy subjects of 18-50 years of age. Intervention: Raw milk, obtained from farms that comply to the high quality requirements for production of raw milk, and that has been screened according to the safety criteria for raw milk.
Besides the specific response to vaccine antigens, the investigators will analyze the anti-HPV immune response in HIV-1-infected men in different strata of immune deficiency. The hypothesis will be tested by stratification by T CD4 + lymphocytes in an attempt to assess the range of the count with the highest possibility of vaccine response. Thus, knowledge of vaccine response in HIV-infected patients, indicate which patients would have greater potential for vaccine response in vivo.
This is a multiple sites phase II trial, randomized, observer-blind, dose ranging, placebo-controlled study to evaluate the immunogenicity, safety, and tolerability of a single intramuscular injection of plant-based Seasonal VLP Quadrivalent Influenza Vaccine administered in elderly subjects (50 years old and more). A total of four hundred fifty (450) subjects will be randomized in six (6) groups of 75 subjects to receive one injection of either a non-adjuvanted low, medium or high dose level of VLP, a low or high dose level of VLP of the quadrivalent VLP influenza vaccine combined with Alhydrogel® as adjuvant or the placebo preparation (100 millimolar (mM) phosphate buffer + 150 mM sodium chloride (NaCl) + 0.01% Tween 80)
The purpose of the Swedish Prison Program which started back in 1987 and up until 2009 was called "The Social Medicine Remand Prison Project" is to target injecting drug users (IDU) with primary and secondary health interventions with regards to injecting and sexual risk behaviours and infectious diseases such as hepatitis C and B, HIV and sexually transmitted infections (STI). The overall aim is to assess the effect of different prevention efforts on HIV/HCV risk behaviour and disease outcome among IDUs over time.
A phase II trial multicenter, observer-blind, randomized, dose-ranging, placebo-controlled study to evaluate the immunogenicity, safety, and tolerability of a single intramuscular injection of plant-derived Seasonal VLP Quadrivalent Influenza Vaccine administered to healthy adults 18-49 years of age. A total of three hundred subjects will be randomized in four (4) groups of 75 subjects to receive one injection of either a low, a medium, or a high dose level of the quadrivalent VLP influenza vaccine or the placebo preparation (100 millimolar (mM) phosphate buffer + 150 mM sodium chloride (NaCl) + 0.01% Tween 80).
REP 2139-Ca is nucleic acid polymer. Nucleic acid polymers have been previously shown to clear serum hepatitis B virus surface antigen (HBsAg) both preclinically (in duck HBV infected ducks) and in human patients and to act synergistically with immunotherapeutic agents such as pegylated interferon-alpha 2a or thymosin alpha-1 to restore host immunological control of HBV infection. HBsAg is an essential component of the hepatitis D virus (HDV), therefore the direct action of REP 2139-Ca in removing serum HBsAg and its synergistic effect with pegylated interferon-alpha 2a is expected to have a significant antiviral effect against HDV infection. This study will examine the safety and efficacy of REP 2139-Ca therapy when used in combination with pegylated interferon alpha-2a in patients with HBV / HDV co-infection. The primary hypothesis to be tested is that this combined dosing regimen is safe and well tolerated in patients with HBV / HDV co-infection which will be assessed by examining the number of patients with adverse events (including reported symptoms and laboratory abnormalities). The secondary hypothesis to be tested is that this combined dosing regimen will have an antiviral effect against HBV / HDV co-infection in these patients which will be assessed by examining the following outcomes: 1. The number of patients with reductions in serum HBsAg. 2. The number of patients with reductions in serum HDAg and HDV RNA 3. The number of patients that experience a sustained antiviral response after treatment is stopped (reductions in serum HBV DNA and HDV RNA). The secondary hypothesis to be tested is that this combination approach can have an effective
The Vancomycin Study is a multi-center, prospective randomized controlled trial that will compare the proportion of deep surgical site infections within 6 months in patients treated with local Vancomycin powder compared to those treated without local Vancomycin powder at the time of fracture fixation.
This study is to evaluate the antiviral efficacy, safety, and tolerability of combination therapy with ledipasvir/sofosbuvir (LDV/SOF) fixed-dose combination (FDC) + vedroprevir (VDV) ± ribavirin (RBV) for 8 weeks in treatment-experienced adults with chronic genotype 1 hepatitis C virus (HCV) infection and cirrhosis.
The purpose of this study is to know the effects of probiotics on the incidence of Necrotizing Enterocolitis (NEC) in preterm infants less than 1500 g.
