Smartphone-enabled optofluidic exosome diagnostic for concussion recovery.

A major impediment to improving the treatment of concussion is our current inability to identify patients that will experience persistent problems after the injury. Recently, brain-derived exosomes, which cross the blood-brain barrier and circulate following injury, have shown great potential as a noninvasive biomarker of brain recovery. However, clinical use of exosomes has been constrained by their small size (30-100 nm) and the extensive sample preparation (>24 hr) needed for traditional exosome measurements.

School-based control of soil-transmitted helminthiasis in western Visayas, Philippines.

We evaluated the effect of a local government unit-led, school-based, teacher-assisted mass drug administration (MDA) treatment of soil-transmitted helminthiasis (STH) on the morbidity of school children in selected provinces of western Visayas, the Philippines. Parasitological assessment was done on stool samples using the Kato-Katz technique. Nutritional status and school performance were also evaluated using secondary data from the Department of Education.

Sentinel surveillance of soil-transmitted helminthiasis in preschool-aged and school-aged children in selected local government units in the Philippines: follow-up assessment.

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.

Machine learning for the New York City power grid.

Power companies can benefit from the use of knowledge discovery methods and statistical machine learning for preventive maintenance. We introduce a general process for transforming historical electrical grid data into models that aim to predict the risk of failures for components and systems. These models can be used directly by power companies to assist with prioritization of maintenance and repair work.

Soil-transmitted helminth and other intestinal parasitic infections among school children in indigenous people communities in Davao del Norte, Philippines.

A significant portion of the population in the Philippines consists of indigenous people (IP) groups, approximately 9% or 8.1 million. Data on the health status of these groups are very limited including the status of soil-transmitted helminth (STH) infections.

Sentinel surveillance of soil-transmitted helminthiasis in selected local government units in the Philippines.

This study describes baseline prevalence and intensity of soil-transmitted helminth infections as well as baseline anthropometric and school performance data among public elementary school children in 6 sentinel provinces in the Philippines. Stratified cluster sampling was used to select 6 provinces, where grade 3 elementary school pupils were surveyed. Secondary anthropometric data and achievement test results of the immediate past academic year were examined.

Field evaluation of malaria rapid diagnostic tests for the diagnosis of P. falciparum and non-P. falciparum infections.

The objective of this study was to evaluate various malaria rapid diagnostic tests as a tool in the detection of P. falciparum and non-P. falciparum infections in field conditions.

A focus of human infection by Haplorchis taichui (Trematoda: Heterophyidae) in the southern Philippines.

We report an exceptionally high rate of infection by Haplorchis taichui (Nishigori, 1924) in human populations on Mindanao Island, southern Philippines. This intestinal fluke is seldom encountered, and this is the first report of high prevalence of infection (36%) in humans by H. taichui in the Philippines.

Infection status of intestinal parasites in children living in residential institutions in Metro Manila, the Philippines.

A small scale survey was performed to know the infection status of intestinal parasite in children of the residential institutions and street communities in Metro Manila, Philippines. A total of 284 stool samples from 11 institutions and 3 street communities was examined by the formalin-ether concentration method. The scotch tape anal swab was adapted to 121 children to investigate the infection status of Enterovius vermicularis.

A comparison of the efficacy of single doses of albendazole, ivermectin, and diethylcarbamazine alone or in combinations against Ascaris and Trichuris spp.

Objective: To determine the efficacy of single doses of albendazole, ivermectin and diethylcarbamazine, and of the combinations albendazole + ivermectin and albendazole + diethylcarbamazine against common intestinal helminthiases caused by Ascaris and Trichuris spp.

Methods: In a randomized, placebo-controlled trial, infected children were randomly assigned to treatment with albendazole + placebo, ivermectin + placebo, diethylcarbamazine + placebo, albendazole + ivermectin, or albendazole + diethylcarbamazine. The Kato-Katz method was used for qualitative and quantitative parasitological diagnosis.

Intestinal heterophyidiasis: an emerging food-borne parasitic zoonosis in southern Philippines.

Heterophyidiasis is an infection of the small bowel by minute intestinal flukes of the genus Heterophyes or related members of the family Heterophyidae. To provide a better understanding of this rarely reported condition, this study attempted to determine the infection rate, intensity of infection as well as the clinical spectrum of heterophyid infection. A stool survey was conducted in barangay San Isidro, Monkayo, Compostela Valley.

Effect of intestinal helminthiasis on nutritional status of schoolchildren.

This study was conducted in a rural agricultural area in Siniloan, Republic of the Philippines. The subjects were the school children. The nutritional status of 58 children infected with helminthiasis (Ascaris lumbricoides and Trichuris trichiura) was compared with that of 19 uninfected controls.

Compostela Valley: a new endemic focus for Capillariasis philippinensis.

A 20 year old female from Compostela Valley Province in the Philippines, presenting with chronic diarrhea, borborygmi, bipedal edema, anorexia and weight loss was seen at Davao Regional Hospital. Her stool specimen, suspected by a local medical technologist to have Capillaria philippinensis ova, was forwarded to the Diagnostic Parasitology Laboratory of the College of Public Health, University of the Philippines Manila. It was examined and found to contain Capillaria philippinensis adults, larvae and eggs.
