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 Nutritional status of 0-5 year old children of small scale fisherfolks from Barangays along the coastal areas of Miagao, IloiloAscano, Maria Epifanie; Borromeo, Ma. Benjafe; Luces, Leslie Ann; Napud, Ma. Salve; Sagge, Jasmine; Tarroja, Aireen Joy (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2003-03)This special problem sought to determine the nutritional status of 0-5 year old children of subsistence fisherfolks from selected barangays along the coastal areas of Miag-ao, Iloilo. The study incorporated anthropometric, clinical, dietary, and socioeconomic data to detect any nutritional disorder and to ascertain nutriture of 0-5 years old children. There were fifty-six fishermen among the 14 coastal areas which served as basis for determining the number of respondents. Ninety-one children aged 0-5 years old comprised the sample population. This descriptive cross-sectional study employed a probability sampling method named two-stage sampling design. This special study utilized an anthropometric data sheet, clinical assessment sheet, 24-hour food recall sheet, and interview schedule to gather appropriate data. The data collected was then subjected to statistical tools such as means, frequency count/distribution, percentages, ANOVA using the EPI-INFO 6 software and the Fil-Anthrop Software of the FNRI-DOST. Findings revealed that 45.1% of the respondents had an average height for age, 37.4% of the respondents were mildly underweight for age, and 54.9% had an average weight for height. Among the ninety-one respondents, the clinical signs exhibited were lack of luster, thinness, and sparseness; dyspigmentation; pale conjunctiva; thyroid gland enlargement; mottled enamel; dental caries; spongy, bleeding gums; and beading of the rib. Moreover, 82.4% of the respondents were below the Recommended Dietary Allowance. Findings have revealed that there is no association between the nutritional status of respondents (ht. for age, wt. for age, wt. for ht.) and the following variables: (a) Age of 0-5 years old children, (b) Sex of 0-5 years old children, (c) family size, (d) Monthly family income, (e) Highest educational attainment of housewives, (f) Clinical signs, (g) Sanitary practices, (h) Crowding index, (i) Feeding practices of housewives, (j) Presence of toilet facilities, and (k) Source of drinking water.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.Item Gross alpha and gross beta radioactivity and heavy metal concentration profiles of well water of the Calahunan dump site, Mandurriao, Iloilo CityAmarante, Hena Charma; Basquez, Mark Anthony; Brunio, Christian Allan; Dable, Nesel; De la Pena, Pamela-Di; Genterola, Janis; Oredina, Josette Marie; Padayhag, Dave (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2005-03)The study aimed to establish presence of radioactivity and concentration of heavy metals specifically lead and chromium in drinking water from wells within one-kilometer radius from the approximated center of the Calahunan dump site. Results showed that four out of twelve wells have positive results fro gross alpha activity and gross beta activity: wells 2A, 2C, 3A, and 3D. Well 2A, 2C and 3D registered alpha activities of 0.54, 0.033 and 0.369 Bq/L respectively while Well 3A registered beta activity of 1.0 Bq/L. Wells 2A and 3D exceeded the radiological limits set by WHO and PNSDW of 0.1 Bq/L for alpha activity and 1.0 Bq/L for beta activity. These wells that are found adjacent to the perimeter fence of the dump site registered alpha activity (wells 2A, 2C and 3D) and beta activity (well 3A). Radiological activities in all other wells sampled registered less than lower limit of detection. For gamma activity, all wells recorded 137- Cs and 134-Cs activity less than the lower limit of detection. For chromium and lead concentration using FAAS, only well 3C has a chromium concentration of 0.0952 ppm and this exceeded the PNSDW standard for chromium in drinking water (0.05 ppm) FAAS has not recorded any value for lead. For chemical constituent analysis using XRF, two wells in zone 1 (LA and IC), have recorded lead concentration of 0.9 and 0.136 ppm, respectively. In zone two, only well 2D registered a lead concentration of 0.248 ppm. In zone 3, well 3C registered a lead concentration of 0.397 ppm. For chromium concentration, only well 2A in zone 2 has a chromium concentration of 1.79 ppm. The spot interview and ocular inspection found out that the following garbage are disposed of indiscriminately tn the dump site: (1) Television picture tubes, (2) Dysfunctional Computer Monitors, (3) Used syringes and needles, (4) Hospital wastes, (5) Automobile batteries and dry cells, (6) scrap iron, tin cans, paint cans, paint cans, etc., (7) polyethylene bottle, glass bottles, and containers of similar types, and (8) other organic and inorganic wastes. Wells whose values for gross alpha, lead, and chromium concentration exceeded the standard are unsuitable for dinking and other domestic uses. The observation that wells (2A and 3D) near the Calahunan dump site registered higher-than-standard alpha activity may be a good basis to conduct further research particularly on the effect of leachate from dump site.Item The step up project: Strengthening teens through empowering programs against unintended pregnancyAlba, Nina Charlyn B.; Anasario, Jc Belle T.; Bautista, Seth Exequiel E.; Caliso, Femmy Rose E.; Catalan, Gabrielle A.; Espanol, Yzabel H.; Gonzaga, Royce Clea Maristel A.; Ilogon, Kent Paolo A.; Leoncio, Mabelle K.; Toledo, Mike T.; Vicencio, Geeza Gem S. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2017-06)Iloilo province is known to have high cases of teenage pregnancy in the Philippines, with the Municipality of Anilao topping since 2013. The STEP UP Project aims to lower the incidence of teenage pregnancy in Barangay Cag-an, Anilao, Iloilo through a positive developmental approach. It consists of a three-step intervention satisfying four component objectives during the six-week community immersion. Objective one is to organize a core group in both municipal and barangay level for the sustainability of the project which included the Local Government Unit of Anilao, barangay officials, and the teens and parents from the barangay. Objective two is to create a venue where teens can comfortably share their problems and sexuality wherein 13 teen facilitators were trained to aid in various activities planned for the project. Objective three is to increase knowledge, attitudes, and practices (KAP) on teenage pregnancy, adolescent health, and gender issues by 75% and with this, a pretest and posttest was administered to teens and parents to evaluate KAP. This resulted to a 6.97% (15.57-16.76) and 7.96% (17.51-18.91) increase in mean scores of teens and parents, respectively. The mean scores of both teens and parents were found to be statistically different at α 0.05 using paired T-test. Objective four is to help teens build confidence, improve their self-esteem, and persuade them to plan out for the future. Thus, a sports clinic was hosted and Buwas Damlag Fair was organized where different government agencies were invited to inspire the teens to pursue careers in the future. Overall, the project was a success since there is an increase of attendance by the parents and teens on activities and lectures, increase of mean scores in the pretest and posttest, and the objectives set were achieved. Implementation of this project to other barangays in Anilao is highly recommended.Item Prevalence of substance use among college students of state colleges in IloiloAgreda, Joji Marie Gela; Corio, Razel Joy Luceno; Hervas, Jeneline Espanol; Icabandi, Donna Joy Tabor; Melarin, Dianne Vallecera; Mosura, Joenalie Montano; Suspeñe, Rhoda Belandres; Vallejo, Arleen Joy Calanao (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2004-04)This study aimed to describe the prevalence, nature, and extent of substance use of college students enrolled in the main campuses of state colleges in Iloilo. There were 402 respondents coming from the main campuses of Iloilo State College of Fisheries (ISCOF), Northern Iloilo Polytechnic State College (NIPSC), Western Visayas College of Science and Technology (WVCST) and the lone campus of New Lucena Polytechnic College (NLPC). Data was collected through a questionnaire which was modified from the model core questionnaire developed by the World Health Organization (WHO). Results showed that 36.1% of the respondents had tried smoking. Their mean age of smoking initiation was 17 years with 13.5% having first tried smoking before 15 years of age. Their top three reasons for smoking are as follows: curiosity (44.1%), for fun (25.5%) and peer pressure (17.2%). Of the respondents who smoked within 30 days prior to the survey, 14.7% consumed more than 5 cigarettes per day. The results also showed that 33.8% of the respondents who have tried smoking usually smoke during parties while their usual place to smoke is either in their houses, dormitories or boarding houses (40.7%). There was a significant relationship between the smoking status of the respondents who have tried smoking and the following: gender (p < 0.0001), age (p = 0.0004) and year level (p < 0.01). On the other hand, smoking status of the respondents who have tried smoking has no significant relationship with the following: annual family income (p = 0.91). living arrangement (p = 0.63) and membership in fraternities/sororities (p = 0.17). Alcoholic use had a higher prevalence (65.4%) than cigarette smoking (36.1%). The mean age of those respondents who have tried drinking was also 17 years with 13.7% having tried drinking at an age below 15 years. Their top three reasons for drinking are: for fun (34.6%), curiosity (29.3%) and because family members drink (12.9%). Seventy percent of the respondents who have tried drinking drank 30 days prior to the survey with 10.9% consuming more than 5 bottles and another 10.9% consuming more than 5 glasses of alcoholic beverages. Of those who have been binge drinking 30 davs prior to the survey, 18.9% have been binge drinking 3 to 5 times. The usual occasion for the respondents to drink is during parties (72.9%) and the usual place for them to drink was either in their houses, dormitories or boarding houses (60.8%). The beverage of choice is beer (59.7%). The drinking status of those who have tried drinking had a significant relationship with the following: gender (p < 0.0001), year level (p = 0.005) and membership to fraternities/sororities (p = 0.04). Meanwhile, drinking status had no significant relationship with age (p = 0.06), annual family income (p = 0.85) and their living arrangements (p = 0.51). Shabu use had a prevalence of 2.7% among the respondents. The mean age of shabu use was also 17 years with 18.2% first trying it at 15 years of age. Their reasons for having tried shabu are: peer pressure (45.5%), curiosity (18.2%) and for fun (18.2%). Within 30 days prior to the survey. 45.5% of those who have tried using shabu have used shabu and 20.0% have used shabu in 20 or more days. They usually use shabu during parties (54.5%) and usually have tried using shabu either in their houses, dormitories and boarding houses (54.6%). Data shows that shabu use had a significant relationship with the following: gender (p = 0.0007). year level (p = 0.003) and fraternity/sorority membership (p = 0.05). It has no significant relationship with age (p = 0.09). annual family income (p = 0.92) and their living arrangements (p = 0.47). Results also showed that 5 % of the respondents have tried smoking marijuana and 4.2% have tried opiate type drugs. The mean age for having tried drugs other than shabu was also 17 years with 26.3 % having tried them at an age below 15. Thirty-one percent of those who have tried other drugs than shabu have tried within 30 days prior to the survey.Item Pesticide exposure, Knowledge, Attitude and Practices (KAP), and laboratory findings of farmers of Barangay San Ambrosio, Igbaras, IloiloAcuesta, Doneza Dee L.; Bernaldo, Alyka Joy D.; De la Pena, Leobert Julienne A.; Diestro, Joan Marie T.; Domingo, Megan Joyce N.; Fortuna, Edward Paul F.; Garrucho, Geraldine F.; Poral, Mechelle Joy L; Suñer, Ma. Alexis Kleanthe D.; Villanueva, Dana Diane C. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2014-04)This is a cross-sectional study which aimed to evaluate the knowledge, attitude and practices (KAP) towards pesticide use, its health effects, and the laboratory findings of farmers from Barangay San Ambrosio, Igbaras, Iloilo. Specifically, it aimed to determine the association between the number of years of pesticide use and the farmers’ MCV values. A total of 115 farm workers were interviewed and 109 (94.8%) of them reported pesticide usage. Among farmers who used pesticides, 90 (82.6%) consented to undergo CBC testing. Descriptive statistics was used for socio-demographic profile, KAP, and health effects of pesticide use. Whereas, Chi- square analysis was used to determine the association between pesticide exposure and MCV values. The farmers were knowledgeable about pesticides and its health effects, the route of entry into the body, and the fate of pesticide residues. Despite knowing the adverse effects of pesticides, 107 out of the 109 pesticide-using farmers (98.2 %) still agreed on the use of pesticides, and only 2 (1.8 %) were against it. They justified that pesticides are effective in killing pests to produce abundant crops and only some farmers knew that biological (61.5%) and natural control (63.3%) can be used as alternatives for pest control. In addition, most farmers (n = 94, 86.2%) used PPE when applying pesticides but were inadequate: with 81 (74.3%) using long-sleeved shirts, but only 17 (15.6%) using gloves, and 5 (4.6%) using eyeglasses. The lack of complete and proper PPE may be a factor for the self-reported health effects, such as dizziness (n = 59, 54.1 %), which was the most predominant, followed by burning sensation in eyes/face (n = 54, 49.5 %) and headache (n = 48, 44.0 %). No significant association was found between years of pesticide use and MCV using the chi-square analysis (x2 = 0.583, p = 0.318). It would be useful to minimise the use of pesticides, encourage alternative measures, lessen the time of pesticide spraying, and encourage the use of complete PPE. Prevention and intervention programmes regarding the use of protective measures and monitoring the health status of farm workers should be implemented.
