BACKGROUND AND OBJECTIVE
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as the causative agent of COVID-19 has significantly challenged the public health landscape in late 2019. After almost 3 years of the first ever SARS-CoV-2 case, the World Health Organization (WHO) declared the end of this global health emergency in May 2023. Although, despite the subsequent drop of COVID-19 cases, the SARS-CoV-2 infection still exhibited multiple waves of infection, primarily attributed to the appearance of new variants. Five of these variants have been classified as Variants of Concern (VOC): Alpha, Beta, Gamma, Delta, and the most recent, Omicron. Therefore, the development of methods for the timely and accurate detection of viral variants remains fundamental, ensuring an ongoing and effective response to the disease. This study aims to evaluate the feasibility of the application of an in-house approach in genomic surveillance for the detection of SARS-CoV-2 variants using in silico designed primers.
METHODSThe primers used for the study were particularly designed based on conserved regions of certain genes in the virus, targeting distinct mutations found in known variants of SARS-CoV-2. Viral RNA extracts from nasopharyngeal samples (n=14) were subjected to quantitative and qualitative tests (Nanodrop and AGE). Selected samples were then analyzed by RT-PCR and amplicons were submitted for sequencing. Sequence alignment analysis was carried out to identify the prevailing COVID-19 variant present in the sample population.
RESULTSThe study findings demonstrated that the in-house method was able to successfully amplify conserved sequences (spike, envelope, membrane, ORF1ab) and enabled identification of the circulating SARS-CoV-2 variant among the samples. Majority of the samples were identified as Omicron variant. Three out of four designed primers effectively bound into the conserved sequence of target genes present in the sample, revealing the specific SARSCoV-2 variant. The detected mutations characterized for Omicron found in the identified lineages included K417N, S477N, and P681H which were also identified as mutations of interest. Furthermore, identification of the B.1.448 lineage which was not classified in any known variant also provided the potential of the developed in-house method in detecting unknown variants of COVID-19.
CONCLUSIONAmong the five VOCs, Omicron is the most prevalent and dominant variant. The in-house direct PCR product sequencing surveillance (DPPSS) method provided an alternative platform for SAR-CoV-2 variant analysis which is accessible and affordable than the conventional diagnostic surveillance methods and the whole genome sequencing. Further evaluation and improvements on the oligonucleotide primers may offer significant contribution to the development of a specific and direct PCRbased detection of new emerging COVID-19 variants.

BACKGROUND
Burn injuries remain a significant global public health problem, causing substantial morbidity, mortality, and economic burden, particularly in low- and middle-income countries where nearly 90% of cases occur. Despite the importance of timely and appropriate first aid in reducing complications, community responses to burn injuries in many settings continue to rely on traditional or non-evidence-based practices.
OBJECTIVESThis qualitative phenomenological study explored community-based knowledge and responses related to the causes and first aid of burn injuries.
METHODSThe study involved ten (10) purposively selected informants residing in South Mangga Dua Urban Village, Central Jakarta, Indonesia. Data collection methods included semi-structured interviews, direct observations, and focus group discussions (FGDs). Thematic analysis was used.
RESULTSThree (3) core domains were identified: (1) community perceptions of burn causes and classifications, (2) indigenous first aid practices used in domestic settings, and (3) sources of knowledge and information pathways related to burn first aid. Participants commonly attributed burns to incidents involving fire, hot liquids, and electrical faults. Their understanding of burn severity was limited to superficial assessments, with little awareness of clinical classifications. First aid responses were largely based on traditional practices such as the application of toothpaste, honey, or aloe vera, while evidencebased practices like using running water were rarely mentioned. Notably, most participants relied on familial teachings and informal community experiences as their primary sources of knowledge, with limited exposure to health professionals or verified media content.
CONCLUSIONCommunity knowledge is culturally rooted but misaligned with medical standards, potentially leading to unsafe practices. Culturally sensitive health education integrating traditional beliefs and accurate information is essential to improve outcomes in burn injury management.

BACKGROUND
Undernutrition remains a public health concern in the Philippines despite multitude of government efforts using different nutrition specific and sensitive interventions. Hence, the role civil society organizations play is important in augmenting the health and nutrition programs in the country. Community feedback is important as they are the receiving end of these programs.
OBJECTIVEThe study aimed to know the perceived impact and community insights on the implemented health and nutrition programs in the four selected sites in the Philippines.
METHODSQualitative program evaluation was used, and 50 discussants were recruited through purposive sampling. Semi-structured interview guide for focus group discussion was utilized to determine the perceived impact of the programs among the discussants, and thematic analysis was used to generate codes and themes.
RESULTSThe implemented health and nutrition programs were found to be a source of hope for the family and community and beyond basic necessities. However, there remain barriers in successful acquisition of new information such as a lack of resources and environmental influences. There are also learned opportunities such as continued support from the Civil Society Organization (CSO), and impact capacity building that are not sponsor-driven.
CONCLUSIONOverall, the participants see the health and nutrition programs as helpful for their children as these programs foster proper child rearing. The programs also empower the parents and the community through capacity building. However, there is a need to revisit implementing rules and guidelines to further maximize the benefits and resources of the programs.

INTRODUCTION
Hypertension is a serious public health issue that puts individuals at risk for various morbidity and mortality indicators. One of the most crucial factors in managing blood pressure and preventing complications is medication adherence which is linked to several determinants. This study explored the correlation between medication adherence among middle-aged hypertensive adults and the different domains of quality of life (QOL), which includes physical, psychological, social relationship and environment.
METHODSThis cross-sectional study involved 96 Filipino residents of Brgy. San Jose, Navotas City aged 35 to 65 years old diagnosed with hypertension and prescribed anti-hypertensive medications. Pearson’s correlation coefficient was used to calculate the correlation between different domains of QOL as well as the overall QOL score.
RESULTSResults revealed a statistically significant but weak positive correlation between overall QOL and medication adherence (r = 0.336, pCONCLUSION
The study demonstrates that while medication adherence is modestly associated with better perceived QOL, especially in physical, psychological and environmental aspects, other factors likely influence both outcomes. These findings highlight the need for holistic, community-based interventions that address not only medication adherence but also environmental and psychosocial barriers to care in managing hypertension.

INRODUCTION
The growing misuse of antibiotics and the escalating threat of antibiotic resistance in the Philippines pose significant public health concerns. While various Knowledge, Attitudes and Practices (KAP) questionnaires on personal antibiotic use have been employed in local studies, none have been fully validated and a standardized, culturally appropriate tool remains lacking.
OBJECTIVEThis study aims to develop a Filipino-translated and culturally adapted KAP questionnaire on personal antibiotic use (KAPQ-PAU-FIL) and evaluate its validity and reliability.
METHODOLOGYThe research consisted of two phases. The first phase is the translation and cross-cultural adaptation of the original questionnaire in collaboration with the UST Sentro sa Salin at Araling Salin. The second phase is the validity and reliability testing of the KAPQ-PAU-FIL using a sample of 176 Filipino adults. This included assessment of its face validity, content validity, construct validity, internal consistency, test-retest reliability and equivalent forms reliability.
RESULTSMost items were translated without difficulty, though four items were modified to better fit the linguistic and cultural context. The KAPQ-PAU-FIL demonstrates strong psychometric properties, with face validity (SFVI/Ave = 0.99), content validity (SCVI/Ave = 0.99), construct validity (CFI = 0.92, RMSEA = 0.06, SRMR = 0.04; FL = 0.60-0.85; ITC = 0.58-0.71), test-retest reliability (ICC = 0.83), internal consistency (α = 0.929) and equivalent forms reliability (p>0.05; κ = 0.62-0.74).
CONCLUSIONThe KAPQ-PAU-FIL is the first ever, Filipino-translated, culturally adapted questionnaire designed to assess KAPQ-PAU-FIL, demonstrating strong validity and reliability to support public health programs against antibiotic misuse.

BACKGROUND AND OBJECTIVE
Evidence base on employment-related medical examinations is highly variable. The aim of this study is to build expert agreement on the appropriate medical and laboratory tests in major industries in Quezon City.
METHODSAn initial scoping review of local, national, and international policies on employment-related diagnostic testing was done. The determination of industries at the selected study site (Quezon City) was accomplished through Pareto analysis. Interviews of key informants and representatives, and a consensus-building process through an expert panel were carried out by the Philippine College of Occupational Medicine (PCOM) Quezon City Chapter. Data gathered was used in the study and analyzed. An initial list of medical tests and diagnostics was drafted and the Modified RAND appropriateness method was used as the choice of mixed methods consensus-building process by an expert panel.
RESULTSRegulations often vary significantly within settings and implementers, particularly the scope, content, and procedures for medical examinations of workers. History taking (including occupational history) and physical examination are the cornerstones of the screening process. CBC and chest x-ray were deemed appropriate screening laboratory tests for asymptomatic preemployment examination, while only chest x-rays were used during periodic examinations. Additional tests for medical surveillance should be based on job demands and specific exposure. For specific chemical exposure, standard references for medical requirements, like from Occupational Safety and Health Administration (OSHA), can be referred to.
CONCLUSIONA shift in how occupational health and safety measures are implemented is needed, particularly in the pre-employment and periodic examination practices, for more relevant screening while preventing unnecessary and low-yield testing and reducing costs for the employer and the employee. An occupational screening checklist/questionnaire based on the results of the study that includes appropriate clinical history-taking, review of systems (ROS), physical examination, and laboratories must be devised, which is to be followed by training in the proper conduction of these medical assessments.

BACKGROUND
The global impact of the COVID-19 pandemic has instigated a profound public health crisis, particularly affecting professionals like dentists who, due to their close interaction with saliva—a potential viral reservoir—and the aerosols generated during specific procedures, face elevated risks of infection. To mitigate this, the Centers for Disease Control and Prevention (CDC) and the Philippine Dental Association (PDA) have established guidelines for averting cross-infection in dental settings
OBJECTIVEThis study, conducted in an urbanized Metro Manila City, delves into the infection control practices of dentists amid the pandemic.
METHODSDentists from a Metro Manila city dental chapter were invited to participate in an online survey (Google Forms) consisting of participants' demographics, patient triage, engineering, administrative controls, disinfection personal hygiene, personal protective equipment (PPE), and waste management practices. Descriptive statistics, employing frequency distributions and percentages, summarized the dentists' adherence to infection control protocols.
RESULTSOut of forty-nine respondents (49), the majority (92%) provided their teams' orientation on COVID-19 infection control protocols before reopening. Notably, 57% deferred elective procedures and 43% postponed aerosolgenerating procedures (AGPs). Only 39% utilized rubber dam isolation during AGPs. Most respondents reported full implementation of recommended administrative controls during the pandemic, with 92% isolating their treatment areas from other parts of the clinic. Most respondents adopted high-efficiency particulate air (HEPA) filtration units (82%) as one of their clinic’s engineering controls, and an extraoral vacuum machine, accounting for 71% of the respondents. The most common disinfection product used by the participants was alcohol, which was at 94%. Additionally, over 90% adhered to all recommended hand hygiene practices for both dental staff and patients. For the waste management protocols, only 55% of the respondents have their infectious waste collected by third-party Treatment Storage and Disposal (TSD) facilities.
CONCLUSIONThe data shows that with the guidelines posted by both the PDA and CDC, the city’s dental practitioners could still provide services to the community in the safest manner at the time by being updated and following the infection control practices suggested by both organizations. Although some areas could have been improved, such as third-party waste management and the utilization of RT-PCR testing, some of these problems could have been attributed to the lack of availability in their areas.

BACKGROUND
Stunting remains a major public health issue in Indonesia, particularly in regions like Pandeglang Regency, where prevalence rates are high. Understanding the contributing factors is essential for targeted interventions.
OBJECTIVEThis study aimed to analyze factors associated with stunting among toddlers using a mixed-methods approach.
METHODSA cross-sectional mixed-methods study was conducted in two health centers in Banten Province from December 2021 to January 2022. Quantitative data were collected using a structured questionnaire and analyzed using chi-square tests (pRESULTS
There is a relationship between maternal knowledge, history of exclusive breastfeeding, history of supplementary feeding, support from health workers, and socio-economic status with the prevalence of stunting. However, the pattern of exclusive breastfeeding and seeking health services in the working areas of Bangkonol Health Center and Kaduhejo Health Center, Pandeglang Regency, is not good enough and needs to be improved. Health workers need to educate mothers with toddlers about patterns of providing complementary feeding, food preparation, and storage, and basic health practices to prevent stunting.
