BACKGROUND
The Philippines has been significantly affected by the HIV epidemic in the Asia-Pacific region, with a notable increase in new cases over the past decade. Despite efforts to promote HIV testing, access to treatment, and awareness campaigns, progress has been slow, particularly among youths. Tangere, a market research application, conducted surveys during and after the COVID-19 pandemic to assess HIV knowledge among Filipinos.
OBJECTIVESThis study aimed to evaluate changes in HIV awareness among young Filipinos during and after the COVID-19 pandemic using data collected via Tangere’s surveys. Specifically, it sought to analyze demographic characteristics, sources of HIV information, and knowledge regarding HIV transmission, prevention, and stigma.
METHODSTangere collaborated with the investigators to develop a questionnaire assessing HIV knowledge among young Filipinos. Surveys were conducted during and after the COVID-19 pandemic, targeting subscribers aged 18-35 years, primarily from the National Capital Region and Luzon area. Data analysis involved calculating frequencies and percentages to summarize demographic characteristics and HIV knowledge. An Independent-Samples Proportions procedure was used to compare HIV knowledge during and after the pandemic.
RESULTSThe survey revealed that while respondents generally possessed reasonable knowledge about HIV, there were notable changes in the awareness during and after the pandemic. Social media and television were identified as primary sources of HIV information. Knowledge regarding HIV transmission and prevention increased postpandemic, particularly concerning preventive measures such as pre-exposure prophylaxis (PREP) and motherto-child transmission (MTCT). However, persistent misconceptions and stigma surrounding HIV remained, indicating the need for continued education and advocacy efforts.
CONCLUSIONThe study underscores the importance of utilizing social media platforms for HIV awareness campaigns, especially among youths who are disproportionately affected by the epidemic. Despite improvements in knowledge, the Philippines has yet to achieve global HIV prevention goals. Continued efforts to enhance awareness, particularly regarding recent advancements in HIV prevention and treatment, are essential for curbing the epidemic and improving public health outcomes nationwide.

In this study, we systematically tested the hypothesis that during the critical developmental period of adolescence, on a macro scale, the concentrations of major excitatory and inhibitory neurotransmitters (glutamate/glutamine and γ‑aminobutyric acid [GABA]) in the dorsal and ventral lateral prefrontal cortex are associated with the brain's functional connectivity and an individual's psychopathology. Neurotransmitters were measured via magnetic resonance spectroscopy while functional connectivity was measured with resting-state fMRI (n = 121). Seed-based and network-based analyses revealed associations of neurotransmitter concentrations and functional connectivities between regions/networks that are connected to prefrontal cortices via structural connections that are thought to be under dynamic development during adolescence. These regions tend to be boundary areas between functional networks. Furthermore, several connectivities were found to be associated with individual's levels of internalizing psychopathology. These findings provide insights into specific neurochemical mechanisms underlying the brain's macroscale functional organization, its development during adolescence, and its potential associations with symptoms associated with internalizing psychopathology.

BACKGROUND
Appropriate use of medication is an important indicator of quality healthcare delivery among children. Previously published studies on drug utilization involved Filipino households in general and were conducted in the 1990s. No recent Philippine studies have been conducted that focus on drug utilization in children.
OBJECTIVETo describe the current prescribing patterns in one primary care service in a rural site in the Philippines using the World Health Organization (WHO) prescribing indicators.
METHODSA cross-sectional study was conducted by review of electronic medical records of patients seen at the primary care facility under the Philippine Primary Care Studies (PPCS) rural site from April 2019 to March 2020. Out of 9,930 total encounters, 623 patient encounters with prescriptions for pediatric patients were included in the study through systematic sampling. The average number of drugs per encounter, percentage of drugs prescribed by their generic names, percentage of encounters with prescribed antibiotics, percentage of encounters with prescribed injections, and percentage of drugs prescribed from the Philippine Drug Formulary were calculated. Values were compared to the cut-offs considered “good practice” for outpatient care in the WHO manual: (1) an average number of less than two drugs per encounter; (2) less than 30% of encounters are prescribed with antibiotics; (3) less than 20% of encounters are prescribed with injections; (4) 100% of drugs are prescribed by generic name; and (5) 100% of drugs are from the formulary.
RESULTSOn the average, three drugs were prescribed per encounter. Most patient encounters (80.9%) involved antibiotics prescription — higher than the WHO standard value of 30%. All drugs were prescribed by generic name and were prescribed from the formulary. Only 0.5% of encounters were prescribed injections, all of which were administered through the intramuscular route. Of the 1,962 prescriptions generated, antibiotics was the most prescribed medication (25.7%). The most common diagnosis was infectious in nature (88.8%).
CONCLUSIONThe primary care service achieved the WHO standard values in terms of prescribing by injections and by generic names. There was a high rate of antibiotic prescriptions at 83%, and a high average number of drugs prescribed per encounter, exceeding the WHO standard value.

In tropical regions, numerous tick-borne pathogens (TBPs) play a crucial role as causative agents of
infectious diseases in humans and animals. Recently, the population of companion and pet dogs has
significantly increased in Vietnam; however, information on the occurrence of TBPs is still limited. The
objectives of this investigation were to determine the occurrence rate, risk factors, and phylogenetic
characteristics of TBPs in dogs from northern Vietnam. Of 341 blood samples tested by PCR, the total
infection of TBPs was 73.9% (252/341). Babesia vogeli (18SrRNA gene – 30.5%) was detected most
frequently in studied dogs followed by Rickettsia spp. (OmpA gene – 27%), Anaplasma platys (groEL
gene – 22%), Bartonella spp. (16SrRNA – 18.8%), Mycoplasma haemocanis (16SrRNA – 9.4%) and
Hepatozoon canis (18SrRNA gene – 1.2%), respectively. All samples were negative for Ehrlichia canis and
Anaplasma phagocytophylum. Co-infection was detected in 31.4% of the samples (107/341) of which,
A. platys/Bartonella spp. (34/94,10%), Rickettsia spp./B. vogeli (19/94, 5.6%), and M. haemocanis/B.
vogeli (19/94, 5.6%) were recorded as the three most frequent two species of co-infection types.
Statistical analysis revealed a significant correlation between TBP infection and several host variables
regarding age, breed, and living area in the current study. The recent findings reported herein, for the
first time in Vietnam, are essential for local veterinarians when considering the appropriate approaches
for diagnosing these diseases. Furthermore, this data can be used to establish control measures for
future surveillance and prevention strategies against canine TBPs in Vietnam.

Objectives:
PhilHealth’s present health benefit scheme is largely centered on in-patient services. This inadvertently incentivizes hospital admissions for increased access to benefit coverage. To address this problem, this study proposes a costing method to comprehensively finance outpatient care. The objective of this paper is to estimate an annual primary care benefit package (PCBP) cost based on experience analysis (actual benefit usage) on the first year of implementation at an urban pilot site.
Methods:
A cost analysis was conducted to assess a disease-agnostic primary care benefit package for an urban
outpatient government facility over the first year of implementation. Costing information was gathered through staff interviews, accounting documents, and usage data from the electronic health records system available on-site.
Results:
The annual primary care cost was defined as the estimated financial coverage for eligible employees and their eligible dependents (n=15,051). The annual utilization rate for consultations was reported at 51%. Of patients who consulted, approximately 38% accessed free available diagnostic procedures and 48% availed of free available medicines. Based on these usage rates, the annual primary care cost for the first year was computed at PhP 403.22 per capita.
Conclusion
Our study shows that on the first year of coverage in a government run urban outpatient facility, an
allocation of PhP 403.22 per capita can allow coverage for a disease-agnostic package (comprehensive); this amount excludes out-of-pocket expenses incurred by the target population of this study. This amount is feasible only when coopted with opportunistic registration, reduction of untargeted check-ups, prior contextual community engagement, and streamlining of patient-transactions through an electronic health record (EHR).

Journal of the Philippine Dermatological Society 2024;33(Suppl 1):44-45
BACKGROUND
Axillary hyperpigmentation is a common cosmetic concern among females of dark skin types. It can affect quality of life and self-esteem of individuals. Currently, there is no standard treatment for axillary hyperpigmentation. Topical and laser therapeutics have been used with variable effectiveness, course and duration of treatment. To date, there are no reported studies using the combination of lasers and topical medications.
OBJECTIVEThe main objective of this study is to determine the effectiveness and safety of Nd:YAG laser with topical niacinamide in reducing axillary hyperpigmentation.
METHODThis was a 20-week, single center, randomized controlled trial that compared the effectiveness of topical niacinamide (group 1), Nd:YAG laser (group 2), and Nd:YAG laser with topical niacinamide (group 3) in reducing axillary hyperpigmentation. Assessment of axillary hyperpigmentation was done according to luminosity difference using Von Luschan’s Chromatic classification scale. Clinical improvement was assessed using Global Aesthetic Improvement Scales (GAIS). Patient satisfaction and adverse effects were noted on follow up visits every 4 weeks.
RESULTSAll 3 treatment groups showed reduction in axillary hyperpigmentation based on significant decrease in median luminosity difference (p valuesCONCLUSION
Q-switch Nd: YAG laser with topical niacinamide is an effective and safe treatment option in reduction of axillary hyperpigmentation.

Objective: The epidemiology of invasive non-typhoidal Salmonella (iNTS) in the Philippines is not well elaborated. The present study describes the serotype distribution and antimicrobial susceptibility patterns of iNTS in the Philippines from 2014 to 2018.
Methods: Invasive NTS isolates were collected through the Department of Health’s Antimicrobial Resistance Surveillance Program (ARSP). The identification of the isolates was confirmed using automated (Vitek®, bioMérieux, Marcy l’Étoile, France) and conventional methods. The isolates were serotyped using the slide agglutination method, and susceptibility testing was performed using Clinical and Laboratory Standards Institute guidelines. Demographic data were collected from the ARSP database.
Results: There were 138 isolates collected from human invasive specimens with 97.8% from blood samples. The most common serotypes were Salmonella Enteritidis (n = 84, 60.9%) and Salmonella Typhimurium (n = 18, 13.0%). Most of the isolates were from males (n = 88, 63.8%) and from the 0–5-year age group (n = 61, 44.2%). The proportions of iNTS isolates resistant to first-line antibiotics were as follows: ampicillin (23.2%), chloramphenicol (9.6%), ciprofloxacin (8.7%), ceftriaxone (2.2%) and trimethoprim-sulfamethoxazole (8.8%). The proportion of isolates with multi-drug resistance was 13.0% (18/138) with the most common resistance profile being resistance to ampicillin-chloramphenicol-ciprofloxacin from Salmonella Enteritidis isolates (n = 5).
Discussion: Resistance to first-line antibiotics limits the therapeutic choices for Salmonella infection. Relevant local antimicrobial resistance data on iNTS may support appropriate empiric therapy among vulnerable populations.

Objective:
Recent advances in epigenetic studies continue to reveal novel mechanisms of gene regulation and control, however little is known on the role of epigenetics in sensorineural hearing loss (SNHL) in humans. We aimed to investigate the methylation patterns of two regions, one in RB1 and another in GJB2 in Filipino patients with SNHL compared to hearing control individuals.
Methods:
We investigated an RB1 promoter region that was previously identified as differentially methylated in children with SNHL and lead exposure. Additionally, we investigated a sequence in an enhancer-like region within GJB2 that contains four CpGs in close proximity. Bisulfite conversion was performed on salivary DNA samples from 15 children with SNHL and 45 unrelated ethnically-matched individuals. We then performed methylation-specific real-time PCR analysis (qMSP) using TaqMan® probes to determine percentage methylation of the two regions.
Results:
Using qMSP, both our cases and controls had zero methylation at the targeted GJB2 and RB1 regions.
Conclusion
Our study showed no changes in methylation at the selected CpG regions in RB1 and GJB2 in the two comparison groups with or without SNHL. This may be due to a lack of environmental exposures to these target regions. Other epigenetic marks may be present around these regions as well as those of other HL-associated genes.
