Development, implementation, and evaluation of a lay responder disaster training package among school teachers in Angeles City, Philippines: using Witte's behavioral model.

OBJECTIVES: The aim of this study was to develop and implement a lay responder disaster training (LRDT) package with the intention to alter the perceived efficacy, perceived threat, and levels of fear among school teachers. STUDY DESIGN: The study used an intervention-based design, wherein we intervened by conducting an LRDT which aimed to affect the participants' responses as defined by Witte's behavioral model (WBM). METHODS: The LRDT package incorporated the usual disaster preparedness information but included the unexplored area of disaster first aid, which is lacking in most training currently being given. The entire LRDT was carried out for two consecutive days by an emergency medical services-accredited competency assessor. Preintervention and postintervention knowledge, level of fear, attitude, intentions, behavior, and a Risk Behavior Diagnosis Scale was assessed using a structured questionnaire based on the WBM. RESULTS: After conducting the LRDT as an intervention, the results show that there was a significant change in the knowledge, behavior, perceived threat, and level of fear among the participants. Other constructs, such as attitude, intentions, and perceived efficacy, were not statistically significant after the intervention. CONCLUSION: In conclusion, knowledge, behavior, and the perceived threat of the school teachers were significantly higher after the LRDT, and their level of fear was significantly lower. Based on these results, we can conclude that both the WBM questionnaire and the LRDT package showed potential in improving disaster risk reduction and management among school teachers in Angeles City, Philippines.

Seroprevalence of selected transfusion transmissible infections among blood donors in Region 3, Philippines: A 5-year retrospective study.

Transfusion of blood is a life-saving intervention that saves many lives. Unsafe practices in blood donation and pre-transfusion testing place people's lives at risk of transfusion transmissible infections (TTIs). The study aims to determine the overall seroprevalence of the selected TTIs for the past 5 years (2013-2017) among blood donors from a hospital in Region 3, Philippines. The trend and distribution of the TTIs according to age group, sex, donor category, and number of donations were also determined. Data extracted include the age, sex, donor category, number of donations, and screening results of all donors from January 2013 to December 2017. The overall seroprevalence of the selected TTIs from over the 5-year period is 4.17%. The seroprevalence rates of hepatitis B, hepatitis C, HIV and syphilis from 2013 to 2017 are 2.87%, 0.48%, 0.10%, and 0.62%, respectively. The age group of 25 to 44 years old showed the highest rate of reactive donors. Also, higher rates of reactive donors are seen among male donors, replacement donors, and first-time donors. The overall seroprevalence of TTIs in the study locale is low and it shows a decreasing trend from 2013 to 2017. Donors who are 25 to 44 years old, males, replacement, and first-time donors showed highest seroprevalence rates of TTIs.

ABO blood group antigens may be associated with increased susceptibility to schistosomiasis: a systematic review and meta-analysis.

Schistosomiasis or bilharzia is a widespread parasitic disease caused by blood flukes of the genus Schistosoma. Some factors have been investigated previously regarding their effect on the pathophysiological mechanism of human schistosomiasis, but the possible influence of the ABO blood group on the severity of Schistosoma infection has been the most promising. Hence, we performed a systematic review and meta-analysis to further investigate the association of the ABO blood group with schistosomiasis susceptibility. Selected publications were retrieved from PubMed up to 21 August 2018, for related studies written in English. Number of cases (with schistosomiasis) and controls (without schistosomiasis) were extracted across all ABO blood types. Odds ratios (OR) and 95% confidence intervals (CI) were computed, pooled and interpreted. Subgroup analysis by the species of Schistosoma infecting the population and the participants' ethnicity was also performed. The overall analysis revealed heterogeneity in the outcomes, which warranted the identification of the cause using the Galbraith plot. Post-outlier outcomes of the pooled ORs show that individuals who are not blood type O are more susceptible (OR: 1.40; 95% CI: 1.17-1.67; PA < 0.001) to schistosomiasis than those who are blood type O (OR: 0.71; 95% CI: 0.60-0.85; PA < 0.001). Subgroup analysis yielded the same observations regardless of the species of schistosome and the ethnicity of the participants. Results of this meta-analysis suggest that individuals who are blood type B and A are more susceptible to schistosomiasis than those who are blood type O. However, more studies are needed to confirm our claims.

Phenotypic evaluation of ESBL- and carbapenemaseproducing Escherichia coli and Klebsiella pneumoniae from a teaching hospital in the Philippines.

Antimicrobial resistance is a worldwide public health concern. Rise in the number of antimicrobial resistant organisms, such as extended spectrum ß-lactamase- (ESBL) and carbapenemase-producing Escherichia coli and Klebsiella pneumoniae, continue to burden millions of people worldwide. E. coli and K. pneumoniae were isolated and collected for four months from a teaching hospital in the Philippines. All isolates were subjected to ESBL and carbapenemase testing using the double disk synergy test and modified Hodge test, respectively. Their pattern of resistance among different classes of antimicrobial agents was also investigated using the Kirby-Bauer disk diffusion test. Among the 32 clinical isolates tested, 28.1% were positive for ESBL production and 6.3% were positive for carbapenemase production. Species-specific classification showed that E. coli (44.4%) has the highest rate of ESBL production whereas both E. coli (5.6%) and K. pneumoniae (7.1%) showed almost similar rates of carbapenemase production. Antimicrobial resistance pattern of drug resistant isolates showed that all organisms were resistant to ampicillin, and majority showed resistance towards ciprofloxacin, cefotaxime, ceftriaxone, and sulfamethoxazole/trimethoprim. ESBL production is seen highest among E. coli isolates while similar rates of carbapenemase production was observed to both E. coli and K. pneumoniae isolates. Overall, antimicrobial resistance continues to rise and poses a huge threat in public health worldwide. Efforts should be made in developing rapid tests for antimicrobial resistance and to search for effective treatment from infections caused by multidrug resistant organisms.
