Item Sagip COUGHamilya: Improving prevention, and case management & care seeking in Sitio Durog, Barangay Palaca, MiagaoAsorio, Leslie S.; Clarito, Thea Joy A.; Dolorosa, Rex Victor V.; Marecap, Mitzi N.; Napulan, Andrea Marie N.; Recabar, James Mathew V.; Rodriguez, Sael D.; Velasco, Princess Monic Q. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2019-06)According to the 2018 Morbidity Diseases Reports of Miag-ao’s Rural Health Unit (RHU), Acute Respiratory Infection (ARI) is the main cause of morbidity among the children in the municipality. Upon further review, the community that was found to have the greatest number of ARI cases is that of Barangay Palaca. To contribute with the reduction of ARI cases in the said community, Project Sagip COUGHamilya was implemented in Sitio Durog. This project aims to reduce the number of current ARI cases among children aging 2 months to 11 years old by at least 50% after the 6-week project implementation. In order to accomplish such goal, the team utilized strategic components such as: (1) establishment of a core group called FamiLEADERS, (2) honing the ARI case management knowledge and skills of the barangay health workers (BHWs) through FamiLINANG sessions for BHWs, (3) improving the mothers’ & guardians’ knowledge, attitude, and practices (KAP) towards care seeking and case management for ARI through FamiLINANG sessions for mothers, and (4) raising the children’s awareness on cough etiquette, proper handwashing, and other key health practices through LINIStorya sessions. Upon implementation, the project’s outputs include the 80% increase in the ARI case management knowledge and skills of BHWs, 44.47% increase in the KAP of the mothers & guardians towards care seeking and case management for ARI, and 12.5% increase in the children’s awareness towards cough etiquette, proper handwashing, and other key health practices. All these results were statistically found to be significant improvements. In conclusion, the strategies done by the group significantly improved the care seeking, case management, and key health practices for ARI in Sitio Durog, Barangay Palaca. As a result, Projesct Sagip COUGHamilya contributed to the reduction of ARI cases by 80%, far exceeding the goal of the project and deeming it to be very effective and successful.Item Effects of Chromolaena odorata leaves as amendments to poultry manure and inorganic fertilizer to improve growth, yield, biomass accumulation and inorganic content of tomato (Lycopersicum esculentum)Balinas, Chona Mae D. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2012-04)Chromolaena odorata (a weed in the family Asteraceae) has been shown to enhance the buildup of organic matter in a fallow system in tropical soil. Therefore, the aim of this study was to to determine the effects of Chromolaena odorata leaves as an amendment to poultry manure and triple 14 inorganic fertilizer on the growth, yield, biomass accumulation and inorganic contents of Lycopersicum esculentum. The field experiment was conducted at Agsanayan Buenavista Guimaras where the weed has wide distribution. The leaves of C. odorata were air dried and composted using Berkeley method. The compost obtained was used as an amendment to either poultry manure and inorganic fertilizer and was tested on tomato for three months in RCBD. Obtained results proved that tested treatments with amendments of C. odorata were significantly higher in lengths of shoots and roots, flower and fruit yield, amount of biomass accumulated and inorganic contents of tomato than those with no amendments of C. odorata. Therefore, C. odorata is an efficient amendment to both organic and inorganic fertilizers. It was suggested that the weed should be utilized to serve as a green manure.Item Composition of abundance of meiofaunal assemblages found in Banate Bay during NE monsoon and early summerArrivas, Johny Kevin B. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2015-05)The study was conducted in Banate Bay, Philippines to describe the composition and abundance of the meiofaunal assemblage in the area. Field sampling was done during December 2012 and March 2013. A total of 41 taxa were identified, dominated by nematodes followed by harpacticoid copepods. The overall mean density of meiofauna in the shallow waters of Banate bay was 28.8 ind.cm'2. The high meiofaunal density recorded in the present study was due to sediment granulometry, water depth and percent organic matter. Macrofauna: meiofauna ratio was also high due to sparse number of macrofauna observed and the physical disturbances associated with seasonal rainfall. The highest density was recorded in March 2013 and the lowest was recorded in December 2012, albeit no significant difference. The temporal distribution of meiofauna was positively correlated with salinity (R = 0.59). Seasonal rainfall also influenced the meiofaunal abundance by affecting turbidity and salinity as well as causing physical disturbances (e.g., storm). Spatial distribution of meiofauna between the stations was influenced by salinity rather than the sediment granulometry, organic matter and turbidity.Item Spatial variations of Benthic meiofauna communities from Palompon Bay, Northern LeyteBalasa, Melvy June (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2013-04)Meiofauna play a significant role in maintaining ecological balance in marine ecosystems especially in the dynamics of the seagrass meadows. The meiofauna links the upper trophic level with detritus-feeding organisms. Only few studies have been conducted in the Philippines, while no studies have been. This study was conducted in Palompon, northern Leyte in November 2011, to determine the spatial distribution of meiobenthic fauna in the area and to compare community structure in terms of species composition, species density, and species diversity among five stations included in the survey. Twenty taxa were identified with nematodes being numerically dominant, followed by harpacticoid copepods. It also showed the highest mean abundance for the entire habitat type. The overall mean density was 194585.1528 ind. m2, with the highest population at station 4. And the lowest population was recorded at station 2. Soft bottom habitat showed the highest recorded mean density among the 5 stations, Harpacticoids mostly dominated sandy substrate while nematodes were widely distributed.Item Assessment of heavy metal traces (Copper and lead) in the soft tissue of Oysters Crassostrea virginicaBalboa, Dexter G. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2010-04-05)The bivalve mollusk Crassostrea virginica is abundant in Brgy. Calaparan, Arevalo and Brgy. Bacong, Dumangas; and are widely consumed by the residence as food. Bioaccumulation of Copper and Lead in the soft tissues of C. virginica from Brgy. Calaparan, Arevalo and Brgy. Bacong, Dumangas were measured and checked if they are still within the permissible levels of Copper and Lead in food based on Median International Standards for metals compiled by the Food and Agricultural Organization of the United Nations. Metal concentrations (μg/g) were determined using Flame Atomic Absorption Spectrophotometer. Mean concentrations of the heavy metals in C. virginica from Calaparan, Arevalo- Cu 27.829, Pb 1.2133; Bacong, Dumangas- Cu 57.834, Pb 0.1338. These levels of Copper and Lead in oyster tissue from both sites are within the the range of Median International Standards for metals and are safe for human consumption. Statistical analysis through one- way ANOVA (F > Fcrit, showed significant difference between sites (Fcrit = 18.51282) for Copper (F value, 215.06569) but not for Lead (F value, 2.25151). The study also provided further solid evidence that bivalve like Crassostrea virginica can recover and concentrate environmentally derived and anthropogenic traces of heavy metals.Item Antimicrobial activity of macrofungal basidiomycetous mycelia against Vibrio spp.Bagacay, Jann Felnesh Exe V. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2023-06)Aquaculture is vital for global food security, producing 50% of the world’s fish. However, infectious diseases caused by fish pathogens like Vibrio species can lead to significant production losses. To address this issue, antimicrobial agents are commonly used. Macrofungal fruiting bodies and mycelia produce bioactive compounds with antimicrobial properties. This study aims to: (a) assess antimicrobial activity in isolated macrofungal samples against the fish bacterial pathogens Vibrio parahaemolyticus and Vibrio cholerae, (b) compare two methods (agar plug and crude extracts) for antimicrobial activity, (c) determine the minimum inhibitory concentration (MIC) using agar well diffusion and the agar plug methods, and (d) identify the macrofungal isolate with the highest antimicrobial activity. Ten morphospecies were collected from the University of the Philippines Visayas Miagao Campus. The samples were evaluated using the agar plug and agar well diffusion methods. The results showed antimicrobial activity against Vibrio cholerae and Vibrio parahaemolyticus. The activity index ranged from 0 to 0.83 and 0.22 to 0.78 for agar wells, and 0 to 1.00 and 0.70 to 1.30 for agar plugs, against V cholerae and V. parahaemolyticus, respectively. Termitomyces globulus and Trametes sp. 1 exhibited the highest activity indices using the agar plug and agar well diffusion methods, respectively. Statistical analysis confirmed significant differences in antimicrobial activity against both test organisms. These findings demonstrate the potential of macrofungi as a valuable source of antimicrobial compounds for controlling fish pathogens in aquaculture. Further research could lead to the identification and utilization of these compounds to minimize production losses and improve disease management in aquaculture.Item Knowledge, attitudes, and practices on dengue vectors of households in Tumagboc Catchment Area, Miagao, IloiloArbizo, Jeric L.; Baldevarona, Rosa Lea S.; Caoyonan, Louise Asuncion D.; Gabasa, Marah Febcy J.; Mapa, Fernie Love D.; Patria, Elaine Joy M.; Tenchavez, Darlene Ruth B.; Trivilegio, Enna Fleur C. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2011-03)Previous studies have shown that knowledge, attitudes and practices have an association with the dengue vector control. As such, the independence of mosquito population on the sociodemographic characteristics and KAP of the household heads in Tumagboc Catchment Area, Miagao, Iloilo was tested. Based on the results, the household heads generally are unemployed, married females aging 41 to 50. Their households are composed of 4 to 7 members with no or one child below 15 years, and usually receive below P 1999 per month. Most of them are informed about dengue fever, but only one had suffered from it in the last two years. Moreover, they have moderate knowledge, poor attitudes, but good practices regarding dengue prevention. The container index is 2.71 for crude mosquito larvae and pupae population, and 0.39 for Aedes sp. The house index is 9.72, while the Breteaux indexis 13.19. Chi-square analysis at 0.05 level of significance confirmed the independence of mosquito larvae and pupae population from monthly income, dengue information reception, knowledge, attitudes and practices. A solid reason was the untimely conduct of the study in the beginning of the summer season, when stagnant water has dried up and with few vulnerable breeding sites.Item Project NINK: Ngiping Inaalagaan para sa Nakangiting KinabukasanAraneta, Francine Nicole M.; Bebita, Valerie Anne N.; Endoma, Vivienne F.; Estanda, Marvyn Kerziel A.; Gupeteo, Mary Pauline Kriszl E.; Lebosada, Billy John F.; Magsipoc, Karla Mae B.; Pabello, Kimberly T.; Samoro, Karmela Marie G.; Villaruel, Rigel Kent Q. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2016-05)Dental caries, also known as cavities or tooth decay, is one of the most prevalent diseases of people worldwide which can start as early as during childhood affecting the primary teeth of children. It is mostly caused by lifestyle-related factors such as poor oral hygiene, lack of dental services, poor habit in brushing teeth and poverty (Ismail et. al. 2007). Iloilo has a high number of dental problems that affect school-aged children. Toothache from dental caries is one of the major causes of absenteeism in elementary schools (Araojo, 2003). The Project Nink aimed to reduce the incidence of dental caries by 80% among school-aged children of Barangay Buenavista Elementary School, Tubungan, Iloilo. A pre-dental check-up, conducted before project implementation found that out of 134 students examined, 125 had dental caries, translating to 9 out of 10 students. For the team to address the existing neglected problem, objectives were set to aid in the project implementation. A reliable and self-sustaining core group was formed for the maintenance and sustainability of the project. To address the insufficient knowledge of the children and community members regarding oral health, a series of health lectures were conducted. Topics for the lectures included basics of the teeth, how cavities form, other diseases that may arise from dental caries, and the like. Training courses for the teachers, health workers and midwife were also conducted by the researchers. Incentives were given out during the lectures and proper educational materials were provided as well. A tooth-brushing sink was constructed together with the teachers, parents, community members and the children, to aid in changing the tooth brushing habits of the children. Dental kits were distributed per child and also for families to aid the child in practicing proper oral hygiene. The children’s post-test results showed that the knowledge regarding oral health increased by 27.54% from their pre-test which was a statistical significant difference. A statistical significant difference (t(41)= - 8.882, p < 0.0005) was also shown in the post-test and pre-test results of the community members which had an increase of 29%. A post dental check-up was conducted to assess the effect of the project, and it was found that the mean prevalence rate of dental carries in the temporary teeth ot student respondents was successfully decreased by 18.4% from 22.73% to 18.55% (dmf index) since pre-project, and therefore, effectively reduced the incidence rate by 100% with 0 new cases. For the permanent teeth (DMF index), there was a 19.75% decrease in prevalence rate and a 100% reduction in the incidence rate with no new cases identified.Item The health status of school-age children in Barangay Ingore, La Paz, Iloilo CityAmamanglon, Keanne Paula H.; Bragancia, Ira May Joy E.; Gulmatico, Gideon M.; Guzman, Virgi Chrisbelle A.; Mercado, Pauline Victoria M.; Orbase, Jannina Faye O.; Reyes, Mary Camille E.; Yap, Maria Lorna Christy C. March (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2011-03)The study is a cross sectional survey to assess the health status of school-age children in barangay Ingore, La Paz, Iloilo City. The health status of the children was evaluated using nutritional status assessment, child care practices of mothers/caretakers and past and present clinical history of disease, and respiratory function. Anthropometry and Clinical Signs were used to directly assess the nutritional status of the children. An Interview Schedule, with mothers/caretakers as respondents was used to determine the socio-demographic characteristics of the household to where the children belong and also to obtain information on their child health care practices. Respiratory or Lung Function was assessed using Lung Peak Flow and Chest Expansion. The results of Anthropometry using the parameters for Weight-for-Age (WFA), Weight-for-Height (WFH) and Height-for-Age (HFA) revealed that 16.3% of the school-aged children were underweight; 10.7% were thin or wasted; 24.4% were stunted, and 4.0% were overweight/obese. The most common clinical signs indicative of malnutrition were pale conjunctiva and the occurrence of dental carries. Most of the children have been breastfed and availed of complete immunization during their pre-school age period. Almost half of them experienced childhood diseases like upper respiratory tract infections (e.g. cough, common colds, asthma, etc.). Peak flow analysis showed that among male, school-age children the average peak flow was 210.6L/minute while among female it was 195.7 L/minute. The computed average peak flow was 203.2 L/minute. The average chest expansion of the subjects was 2.4 cm and the chest expansion of male and female school-age children was 2.4 centimetres. The results obtained in this study can be used as a baseline for future studies especially in the light of the recent operation of a coal-fired power plant which might affect the health status of vulnerable age groups like pre-school and school-age childrenItem Risk zone mapping of 2010 dengue fever and dengue hemorrhagic fever cases in the Province of Iloilo based on land coverAndrada, Thresdale; Cañonero, Gertrude Mikee; España, Regine Marie; Puno, Abigail; Sarangaya, Dorothy Rose; Tan, Leonard; Tejada, Ma. Corazon (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2013-04)Dengue is considered as one of the most important vector-borne diseases in many tropical and subtropical countries. Iloilo Province had 8201 cases in 2010. Heterogeneity in the risk of disease transmission results from spatial heterogeneity in both land use and land cover. Thus, the present study was conducted to identify the risk zones of Dengue Fever and Dengue Hemorrhagic Fever in Province of Iloilo in 2010 based on land cover types by using GIS software. Results of the study show that all land covers in the 6th district pose moderately low risk on dengue incidence. In the case of the 1st district of Iloilo, on the other hand, water bodies have the highest probability of dengue incidence, while the rest of the districts (2nd, 3rd, 4th, 5th). built-up areas have the highest probability of dengue incidence. The land cover type in Iloilo, therefore, with the highest risk for dengue incidence are built up areas due to its high population density, multitude of households and stagnant water areas.
