Filter by:Bacillus Calmette-Guérin (BCG) vaccination is recommended at birth to protect against tuberculosis (TB) in countries with high TB burden. BCG is supplied in multidose vials with limited durability after reconstitution. In Guinea-Bissau, this has led to a practice of only opening a BCG vial at specific days, and only if sufficient children are present. Therefore, BCG vaccination is frequently delayed. Accumulating evidence indicates that BCG has beneficial effects on survival beyond the specific protection against tuberculosis, so called non-specific effects (NSEs). The hypothesis of this study is that increasing the availability of BCG and vaccinating children at the first health-facility contact can reduce early infant non-accidental mortality by 25%. In a cluster-randomised crossover trial, 23 health facilities (HFs) in three rural regions in Guinea-Bissau will be randomised to either continue with current practice (typically BCG vaccination once a week if a sufficient number of children are present for vaccination); or to offer additional BCG vaccines to make BCG available every day and open a vial of BCG if there is just one eligible child present. All children born in the three regions and registered during the study period, will be eligible for inclusion into the trial 1 day after birth. If consent is given by the mother, the child will be followed until day 42 after birth, when other vaccines are scheduled to be given. The primary outcome will be non-accidental mortality, secondary outcomes are non-accidental hospital admissions, non-accidental neonatal mortality and cost-effectiveness of making BCG available at the first health-facility contact.
When children with chronic granulomatous disease (CGD) got BCG infection the treatment would be a tough task. The goal of the proposed research is to observe weather vitamin D supplementation can help the CGD children get through this challenge.
A prospective observational study to re-establish a new prognostic model for predicting the outcome in patients with non-muscle invasive bladder cancer (NMIBC) using the current recommendation regimen for intermediate and high risk groups and including all potential and highly prognostic factors.
