BACKGROUND Few studies have monitored late presentation (LP) of HIV infection over the European continent, including Eastern Europe. Study objectives were to explore the impact of LP on AIDS and mortality. METHODS AND FINDINGS LP was defined in Collaboration of Observational HIV Epidemiological Research Europe (COHERE) as HIV diagnosis with a CD4 count <350/mm(3) or an AIDS diagnosis within 6...
OBJECTIVES The aim of this study was to assess the risk of injuries among children exposed to a stressful life exposure (defined as bereavement) before conception or during fetal life. DESIGN Population-based cohort study. SETTING Denmark. PARTICIPANTS All singleton births in Denmark between 1 January 1995 and 31 December 2006 were identified. These newborns were then linked to mothers, f...
Engineering economy set of mathematical techniques for economic evaluation of investment projects that present value and internal rate of return method are among the most important of these methods. Managers and investors have many reasons to using internal rate of return greater willingness shown. This is while the serious problems associated with using internal rate of return method. In recen...
BACKGROUND For disease surveillance, manual data collection using paper-based questionnaires can be time consuming and prone to errors. We introduced smartphone data collection to replace paper-based data collection for an influenza sentinel surveillance system in four hospitals in Kenya. We compared the quality, cost and timeliness of data collection between the smartphone data collection syst...
AIM To analyse factors associated with fractures in children with cerebral palsy (CP) in different levels of Gross Motor Function Classification System (GMFCS). METHOD This was an epidemiological retrospective study of a total population of 536 children (214 females, 322 males) with CP born between 1990 and 2005. CP type was unilateral spastic (n=159), bilateral spastic (n=225), ataxic (n=60)...

where Eq. A1.1a is for dissolved species, and Eq. A1.1b is for solid species. Here, t is time, and x is the depth coordinate below the sediment–water interface. U is the advection (burial) velocity. Rj values are the rates of chemical and biochemical reactions, and nij is the stoichiometric coefficient of species i in reaction j. Q is the sediment porosity. The factor j is equal to (1 2 Q)r, wh...
The incidence of psychotic disorders varies between geographical areas, however less is known about whether it over time in the same region. Analyzing this temporal variation could improve allocation healthcare resources and our understanding aetiology disorders. This study aimed to determine there was a change six-year period. Young people aged 15 24 presenting with first episode psychosis (FE...
