Trends in dengue research in the Philippines: A systematic review.

Abstract: Dengue is an important public health problem in the Philippines. We sought to describe the trends in dengue research in the country. We searched four databases and identified published studies on dengue research in the Philippines during the past 60 years. We reviewed 135 eligible studies, of which 33% were descriptive epidemiologic studies or case series, 16% were entomologic or vector control studies, 12% were studies on dengue virology and serologic response, 10% were socio-behavioral and economics studies, 8% were clinical trials, 7% were on burden of disease, 7% were investigations on markers of disease severity, 5% were on dengue diagnostics, and 2% were modeling studies. During the last decade, dengue research in the Philippines has increased and evolved from simple descriptive studies to those with more complex and diverse designs. We identified several key topics where more research would be useful.

Sentinel Surveillance of Soil-Transmitted Helminthiasis in Preschool-Aged and School-Aged Children in Selected Local Government Units in the Philippines Follow-up Assessment

Abstract: This study was a follow-up to the baseline nationwide survey of soil-transmitted helminth (STH) infections in preschool-aged children in the Philippines and in school-aged children in selected sentinel sites to assess the Integrated Helminth Control Program of the Department of Health. The objective of the study was to describe the current prevalence and intensity of STH infections in preschool-aged and school-aged children in 6 sentinel provinces and to compare these data with baseline findings. A cross-sectional study design was used to determine the prevalence and intensity of STH infections. Parasitological assessment involved the examination of stool samples by the Kato-Katz method. Although parasitological parameters in the 2 age groups at follow-up showed significant reductions from the baseline, these parameters remained high despite 3 years of mass drug administration (MDA). Efforts toward achieving high MDA coverage rates, provision of clean water, environmental sanitation, and promotion of hygi...

The Miocene to Pleistocene colonization of the Philippine archipelago by Begonia sect. Baryandra (Begoniaceae)

Abstract: Premise of the study One third of the species-rich Philippine flora is endemic, and most of the islands in the archipelago have never been connected to a continental region. We currently lack any well-sampled angiosperm phylogenies that span the archipelago, prohibiting the formation of informed hypotheses as to the evolution of this rich and highly endemic flora. Methods We produced time-calibrated phylogenetic trees from both nuclear (ITS) and chloroplast (ndhA intron, ndhF-rpl32 spacer, rpl32-trnL spacer, trnC-trnD spacer) regions of 41 species of Begonia sect. Baryandra, all except one endemic to the Philippines. Historical biogeography was reconstructed across the chloroplast phylogeny using a Bayesian binary method of character optimization. Comparison of phylogenies from the two genomes permitted insight into the prevalence of hybridization in the group. Key results The Philippine archipelago was colonized by Begonia sect. Baryandra in the late Miocene, via long-distance dispersal from western Malesia and a point of entry likely to be in the northwestern region of the archipelago. Palawan, Luzon, and Panay all bear early-branching lineages from this initial colonization. There have been Plio-Pleistocene dispersals from these islands into Borneo and Mindanao. Hybridization was common between species as evidenced by haplotype sharing and phylogenetic incongruence. Conclusions The phylogenies show a high degree of geographic structure, which millions of years of exposure to typhoons have not blurred, showing long-term species and population stability. The recent dispersals to Mindanao are congruent with the geologically recent arrival of the island at its current latitude in the southern Philippines.

The role of community health workers in malaria control in the Philippines.

Abstract: The barangay health workers (BHWs) or government-trained health volunteers have been operating in rural villages in the Philippines since 1981. Although malaria is a consistently recognized health problem, the BHWs do not contribute optimally to control activities even in endemic areas. This is so because of inadequate training, insufficient logistic support, poorly sustained motivational schemes and lack of community support. Prospects for involvement in malaria control are numerous, however there is need to enhance the existing BHW Program.

A review of Japanese encephalitis cases in the Philippines (1972-1985).

Abstract: Few studies have shown that JE does occur in the Philippines with the majority of the cases affecting the 1-10 year age group in places where rice fields abound. The morbidity rate is 15-17%, with a mortality rate of about 7-30%.
