[Ab] Resumo:OBJECTIVES: We investigated the short-term impact of Typhoon Haiyan, one of the strongest typhoons ever to make landfall, on the pattern of admissions in two hospitals in Eastern Visayas, the Philippines. METHODS: This study took place at Eastern Visayas Regional Medical Center (EVRMC) in Tacloban, and Ormoc District Hospital (ODH) in Ormoc. We determined whether there were differences in the pattern of admissions between the week before and the three weeks after Haiyan by using information on sex, age, diagnosis, ward and outcome at discharge from patient records. RESULTS: There was a drop in admissions in both hospitals after Haiyan as compared to before. Admissions climbed back to the baseline after ten days in EVRMC and after two weeks in ODH. When comparing the period after Haiyan to the period before, there was a relative increase in male versus female admissions in ODH (OR 2.8, 95%CI 1.7-4.3), but not in EVRMC. Patients aged ≥50 years and 0-14 years had the highest relative increase in admissions. There was a relative decrease in admissions for the ICD10 group 'Pregnancy, childbirth and the puerperium' (OR 0.4, 95%CI 0.3-0.6), and an increase in 'Certain infectious and parasitic diseases' (OR 2.1, 95%CI 1.2-3.5), mainly gastroenteritis, and 'Diseases of the respiratory system' (OR 1.8, 95%CI 1.0-3.0), mainly pneumonia, compared to all other diagnosis groups in ODH. Out of all reasons for admission within the study period, 66% belong to these three ICD-10 groups. Data on reasons for admission were not available for EVRMC. CONCLUSIONS: The observed reduction in patients after the Typhoon calls for ensuring that hospital accessibility should be protected and reinforced, especially for pregnant women, by trying to remove debris in the direct hospital vicinity. Hospitals in areas prone to tropical cyclones should be prepared to treat large numbers of patients with gastroenteritis and pneumonia, as part of their disaster plans.

[Ti] Título:Early onset of type 2 diabetes among visible minority and immigrant populations in Canada.

[Ab] Resumo:OBJECTIVES: Type 2 diabetes is a chronic condition that affects nearly over three million Canadians, including immigrants. The timing of the first onset of diabetes has been linked to several other severe diseases. Yet, there is a dearth of empirical studies that examine the timing of the first onset of diabetes among Canadians, in general, and among immigrants and ethnic minority populations within Canada, in particular. DESIGN: Applying event history techniques to the 2013 Canadian Community and Health Survey, we address this research void by examining factors that contribute to the first onset of diabetes among immigrant and visible minority populations in Canada (N = 8905). Given the gendered patterns in the epidemiology of diseases and the differences in risk factors for men and women, gender-specific models were estimated. RESULTS: Results showed that South Asian, Black and Filipino women developed diabetes earlier, compared to women from the UK. Similarly, South Asian, Chinese, Filipino, Black, South East Asian and Arab men developed diabetes earlier than men from the UK. A significant and important finding of this analysis was that the risks of developing diabetes vanished completely for Black and Filipino women, after accounting for lifestyle factors. For South Asian women, however, there was significant attenuation in their risks after accounting for lifestyle factors. The findings were strikingly different for immigrant men. Specifically, their risks of developing diabetes increased after accounting for lifestyle factors. CONCLUSIONS: These results suggest the development of gender-specific and lifestyle interventions, targeted at specific immigrant groups with increased risks of developing diabetes earlier in the life course.

[Ti] Título:Protecting children from rabies with education and pre-exposure prophylaxis: A school-based campaign in El Nido, Palawan, Philippines.

[Ab] Resumo:BACKGROUND: Rabies remains endemic in the Philippines. A study was conducted in El Nido, Palawan, Philippines to: (i) detect the true incidence of animal bites in school children aged 5-14 years using active surveillance and compare these data to estimates from the existing passive surveillance system, (ii) evaluate the impact of rabies prevention education and pre-exposure prophylaxis (PrEP) on animal bite incidence, and (iii) assess the health economic impact of the interventions. METHODOLOGY AND PRINCIPAL FINDINGS: A cohort of 4,700 school children was followed-up for any suspect rabies exposures between January 2011 and December 2012. Data on animal bite incidence from the study cohort were compared to that obtained from a review of consultation records at the Animal Bite Treatment Center (ABTC). PrEP was offered to children in all 27 public elementary schools in El Nido (in January to February 2012). Teachers were given a manual for integrating rabies in the public elementary school curriculum during the school year 2012-13. Active surveillance of the cohort revealed a higher incidence of suspect rabies exposures than that from passive surveillance. Despite a decrease in the number of Category III bites, there was no significant decrease in overall bite incidence as a result of the interventions. However, there was an increase in rabies awareness among school children in all grade levels. There was also a high level of acceptability of PrEP. Children who received PrEP and subsequently were bitten only needed two booster doses for post-exposure prophylaxis, resulting in substantial cost-savings. CONCLUSIONS/SIGNIFICANCE: The true burden of animal bites remains underestimated in ABTC records. PrEP is advantageous in selected population groups, i.e. school-aged children in rabies endemic areas with limited access to animal and human rabies prevention services. Educating school children is beneficial. Strengthening veterinary interventions to target the disease at source is important.

[Ab] Resumo:SETTING: Estimates of the tuberculosis (TB) burden in the Philippines are largely dependent on prevalence surveys. OBJECTIVE: To conduct a prospective community-based survey to generate epidemiological data on TB among patients seeking care in public health centres in a rural municipality in the Philippines. DESIGN: Prospective surveillance and follow-up of presumptive TB cases from May 2013 to July 2015. RESULTS: Of 1622 participants with presumptive TB, 468 (28.8%) (95%CI 26.6-31.1) were diagnosed with TB. The annual TB case notification rate in San Juan was 212 (95%CI 184-242) per 100 000 population. There were nine TB-attributable deaths during the study period. Only 8.8% (95%CI 6.2-11.32) of the cases were children aged <15 years; 274 (58.5%) cases were bacteriologically confirmed. Of 210 isolates tested for antimicrobial resistance, 49 (23.3%, 95%CI 17.58-29.02) were resistant. Resistance to isoniazid (INH) was common (n = 33, 15.7%); multidrug-resistant TB was 1.9%. CONCLUSION: TB remains an important health problem in the Philippines. We identified low case detection of TB in children and high INH resistance rates in this rural community.

[Ab] Resumo:Roseoflavin is the only known riboflavin (vitamin B2) analog with antibiotic properties. It is actively taken up by many micro-organisms and targets flavinmononucleotide riboswitches and flavoproteins. It is described as the product of the tentatively named 'Streptomyces davawensis' JCM 4913. Taxonomic analysis of this strain with a polyphasic approach showed that it is very closely related to Streptomyces cinnabarinus (DSM 40467). The two Streptomyces isolates were obtained from different geographical locations (the Philippines and the Kamchatka Peninsula, respectively), their genomes have been sequenced and the question was whether or not the two isolates were representatives of the same species. As we also worked with another isolate of Streptomyces cinnabarinus JS 360, the producer of the cinnabaramides, we wanted to clarify the taxonomic position of the three isolates by using a polyphasic approach. After analysis of the 16S rRNA gene sequence, we found in total 23 species of the genus Streptomyces that showed a similarity higher than 98.5 % to the three strains. We showed that 'S. davawensis' JCM 4913 and S. cinnabarinus DSM 40467 were very closely related but belong to two different species. Hence, we validate 'S. davawensis' as Streptomyces davaonensis sp. nov. with the type strain JCM 4913 (=DSM 101723 ). In addition, the cinnabaramide producer can be clearly differentiated from S. davaonensis and this isolate is described as Streptomyces cinnabarigriseus sp. nov. with strain JS360 (=NCCB 100590 =DSM 101724 ) as the type strain.

[Ab] Resumo:A Gram-stain-negative, rod-shaped bacterium, designated 157 , was isolated from seawater collected from the Philippine Sea. Cells of strain 157 grew in medium containing 0.5-10.0 % NaCl (w/v, optimum 3 %), at pH 6.0-8.5 (optimum 7.0) and at 15-40 °C (optimum 30 °C). Tweens 20, 40 and 80 as well as urea were hydrolysed. The 16S rRNA gene sequence of strain 157 had a high sequence similarity with respect to Pseudooceanicola marinus AZO-C (97.2 %), and exhibited less than 97.0 % sequence similarity to other type strains of the species with validly published names. Phylogenetic analyses revealed that strain 157 fell within a cluster comprising the Pseudooceanicola species and formed a coherent clade with P. marinus AZO-C and Pseudooceanicola antarcticus Ar-45 . Strain 157 exhibited average nucleotide identity values of 74.5 and 74.9 % to P. marinus LMG 23705 and P. antarcticus Ar-45 , respectively. In silico DNA-DNA hybridization analysis revealed that strain 157 shared 20.2 % DNA relatedness with P. marinus LMG 23705 and 20.6 % with P. antarcticus Ar-45 , respectively. The sole isoprenoid quinone was ubiquinone 10. The major fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c), C19 : 0 cyclo ω8c, C16 : 0 2-OH and C16 : 0. The major polar lipids were phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, one unidentified aminolipid and one unidentified glycolipid. The DNA G+C content was 64.6 mol%. According to the phylogenetic, chemotaxonomic and phenotypic data, it represents a novel species of the genus Pseudooceanicola, for which the name Pseudooceanicolalipolyticus is proposed. The type strain is 157 (=KCTC 52654 =MCCC 1K03317 ). In addition, the description of the genus Pseudooceanicola is emended and Oceanicola flagellatus is reclassified as Pseudooceanicola flagellatus comb. nov., with the type strain DY470 (=CGMCC 1.12664 =LMG 27871 ) proposed.

[Ab] Resumo:This study maps distribution and spatial congruence between Above-Ground Biomass (AGB) and species richness of IUCN listed conservation-dependent and endemic avian fauna in Palawan, Philippines. Grey Level Co-Occurrence Texture Matrices (GLCMs) extracted from Landsat and ALOS-PALSAR were used in conjunction with local field data to model and map local-scale field AGB using the Random Forest algorithm (r = 0.92 and RMSE = 31.33 Mg·ha-1). A support vector regression (SVR) model was used to identify the factors influencing variation in avian species richness at a 1km scale. AGB is one of the most important determinants of avian species richness for the study area. Topographic factors and anthropogenic factors such as distance from the roads were also found to strongly influence avian species richness. Hotspots of high AGB and high species richness concentration were mapped using hotspot analysis and the overlaps between areas of high AGB and avian species richness was calculated. Results show that the overlaps between areas of high AGB with high IUCN red listed avian species richness and endemic avian species richness were fairly limited at 13% and 8% at the 1-km scale. The overlap between 1) low AGB and low IUCN richness, and 2) low AGB and low endemic avian species richness was higher at 36% and 12% respectively. The enhanced capacity to spatially map the correlation between AGB and avian species richness distribution will further assist the conservation and protection of forest areas and threatened avian species.

[Ti] Título:Partitioning no-take marine reserve (NTMR) and benthic habitat effects on density of small and large-bodied tropical wrasses.

[Ab] Resumo:No-take marine reserves (NTMRs) are increasingly implemented for fisheries management and biodiversity conservation. Yet, assessing NTMR effectiveness depends on partitioning the effects of NTMR protection and benthic habitat on protected species. Such partitioning is often difficult, since most studies lack well-designed sampling programs (i.e. Before-After-Control-Impact-Pair designs) spanning long-term time scales. Spanning 31 years, this study quantifies the effects of NTMR protection and changes to benthic habitat on the density of tropical wrasses (F. Labridae) at Sumilon and Apo Islands, Philippines. Five species of wrasse were studied: two species of large-bodied (40-50 cm TL) Hemigymnus that were vulnerable to fishing, and three species of small-bodied (10-25 cm TL) Thalassoma and Cirrhilabrus that were not targeted by fishing. NTMR protection had no measurable effect on wrasse density, irrespective of species or body size, over 20 (Sumilon) and 31 (Apo) years of protection. However, the density of wrasses was often affected strongly by benthic cover. Hemigymnus spp. had a positive association with hard coral cover, while Thalassoma spp. and Cirrhilabrus spp. had strong positive associations with cover of rubble and dead substratum. These associations were most apparent after environmental disturbances (typhoons, coral bleaching, crown of thorns starfish (COTS) outbreaks, use of explosives and drive nets) reduced live hard coral cover and increased cover of rubble, dead substratum and sand. Disturbances that reduced hard coral cover often reduced the density of Hemigymnus spp. and increased the density of Thalassoma spp. and Cirrhilabrus spp. rapidly (1-2 years). As hard coral recovered, density of Hemigymnus spp. often increased while density of Thalassoma spp. and Cirrhilabrus spp. often decreased, often on scales of 5-10 years. This study demonstrates that wrasse population density was influenced more by changes to benthic cover than by protection from fishing.

[Ab] Resumo:BACKGROUND: Cases of acute respiratory tract infection caused by Pteropine orthoreovirus (PRV) of the genus Orthoreovirus (family: Reoviridae) have been reported in Southeast Asia, where it was isolated from humans and bats. It is possible that PRV-associated respiratory infections might be prevalent in Southeast Asia. The clinical course of PRV is not fully elucidated. METHODS: The virulence, pathology, and pathogenesis of two PRV strains, a human-borne PRV strain (isolated from a patient, who returned to Japan from Bali, Indonesia in 2007) and a bat-borne PRV (isolated from a bat [Eonycteris spelaea] in the Philippines in 2013) were investigated in BALB/c mice using virological, pathological, and immunological study methods. RESULTS: The intranasal inoculation of BALB/c mice with human-borne PRV caused respiratory infection. In addition, all mice with immunity induced by pre-inoculation with a non-lethal dose of PRV were completely protected against lethal PRV infection. Mice treated with antiserum with neutralizing antibody activity after inoculation with a lethal dose of PRV showed a reduced fatality rate. In this mouse model, bat-borne PRV caused respiratory infection similar to human-borne PRV. PRV caused lethal respiratory disease in an animal model of PRV infection, in which BALB/c mice were used. CONCLUSIONS: The BALB/c mouse model might help to accelerate research on the virulence of PRV and be useful for evaluating the efficacy of therapeutic agents and vaccines for the treatment and prevention of PRV infection. PRV was shown for the first time to be a causative virus of respiratory disease on the basis of Koch's postulations by the additional demonstration that PRV caused respiratory disease in mice through their intranasal inoculation with PRV.
