BACKGROUND National and subnational level surveys are important for monitoring disease burden, prioritizing resource allocation, and evaluating public health policies. As mobile phone access and ownership become more common globally, mobile phone surveys (MPSs) offer an opportunity to supplement traditional public health household surveys. OBJECTIVE The objective of this study was to systemat...

BACKGROUND Health interview surveys are important data sources for empirical research in public health. However, the diversity of methods applied, such as in the mode of data collection, make it difficult to compare results across surveys, time, or countries. The aim of this study was to explore whether the prevalence rates of health-related indicators amongst adults differ when self-administer...

BACKGROUND Random digit dialing is often used in public health research initiatives to accrue and establish a study sample; however few studies have fully described the utility of this approach. The primary objective of this paper was to describe the implementation and utility of using random digit dialing and Computer Assisted Telephone Interviewing (CATI) for sampling, recruitment and data co...

Intestinal parasites are involved in the health and wellbeing of cats some them, due to their zoonotic potential, represent a problem for public health. This study aimed assess prevalence parasitic infections with gastrointestinal signs. Fecal samples collected from 137 were analyzed by flotation method using sodium chloride saturated solution. The overall intestinal was 50.4%. significantly (p...

The numerical solution of discrete-time algebraic Ric-cati equations is discussed. We propose to compute an approximate solution of the discrete-time algebraic Riccati equation by the (butterry) SZ algorithm. This solution is then reened by a defect correction method based on Newton's method. The resulting method is very eecient and produces highly accurate results.

Eggs of Toxocara cati were found in the feces of Didelphis albiventris from a peridomestic urban environment in Brazil. Negative fecal tests following short-term captivity of the opossums, as well as the absence of ascaridids during necropsy, suggest the occurrence of pseudoparasitism. Implications of the findings for the epidemiology of toxocariasis are discussed.

BACKGROUND Mobile phone ownership and access have increased rapidly across low- and middle-income countries (LMICs) within the last decade. Concomitantly, LMICs are experiencing demographic and epidemiologic transitions, where non-communicable diseases (NCDs) are increasingly becoming leading causes of morbidity and mortality. Mobile phone surveys could aid data collection for prevention and co...
