It is therefore important to examine the burden of acute respiratory infections at a large children's hospital to determine pathogen prevalence, occurrence of co-infection, prevalence of co-morbidities and diagnostic yield of sampling methods.
Our study has attempted to address this knowledge gap by describing viral pathogen prevalence, occurrence of co-infection, diagnostic yield of sampling methods and presence of co-morbidity in patients with ARI caused by 2009 pdmH1N1 and other respiratory viruses, in a large paediatric teaching hospital in the North West of England over a year between April 2010 and March 2011.
They are used for making socioeconomic comparisons over time in terms of disease prevalence or occurrence.
We propose to conduct a systematic review to determine the prevalence and occurrence of dyslipidaemia in adult populations within countries in Africa.
A single population proportion formula at 95% CI with 5% of marginal error at 50% of prevalence of occurrence was used to determine sample size.
However, many authors notice the prevalence of occurrence of the subclinical left ventricle diastolic dysfunction among patients with psoriasis in comparison with healthy population.
Anyway, due to the relatively high prevalence, indigenous occurrence and severe clinical manifestations toxoplasmosis can be considered to be one of the most important true zoonotic parasitoses in the Nordic countries.
The search was conducted using multiple combinations of the following key words: 1) alcohol, ethanol, FASD, FAS, pFAS, ARND, ARBD, PAE; 2) consum*, drink*; 3) maternal, mother, primigravida, wom*n; 4) pregnan*, prenatal; 5) biomarker, fatty acid ethyl ester, meconium (analysis), self-report; and 6) prevalence, frequenc*, occurrence.
The prevalence (lifetime occurrence) rate of cancers of the reproductive system (uterus, ovary, cervix and vagina) and breast cancer was determined for 5,398 living alumnae, 2,622 of whom were former college athletes and 2,776 non-athletes, from data on medical and reproductive history, athletic training and diet.
Official figures for the prevalence and occurrence of drug abuse in different countries are currently obtained from population surveys integrated with crime statistics, medical records, and drug production and seizure rates [ European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) 2006; United Nations Office of Drugs and Crime (UNODC) 2007a].
Knowledge about the prevalence, co-occurrence, and correlates of lifestyle related behaviors of overweight women is needed to inform the design of health promotion interventions for weight loss.
