Background:
Consumption and abuse of alcohol remains a significant cause of concern worldwide. Furthermore, there is evidence of the association between chronic alcohol use and reduced life expectancy.
Objectives:
To study the effects of Garcinia binucao extract (GBE) supplementation on lifespan of Drosophila
melanogaster, in the presence or absence of chronic alcohol exposure.
Methods:
D. melanogaster was mass cultured and given GBE supplementation in high (1 mg/mL) and low (200 µg/mL) sublethal doses. D. melanogaster flies were divided into groups - with and without chronic alcohol exposure, and their respective lifespans were monitored.
Results:
In D. melanogaster without alcohol exposure, mean lifespan was highest in the control flies (38.15 days), followed by high-dose GBE (34.42 days), low-dose GBE (33.24 days), and DMSO (22.29 days). In D. melanogaster chronically exposed to alcohol, the longest mean lifespan was observed in flies treated with high-dose GBE (33.80 days), followed by low-dose GBE (33.63 days), the DMSO group (30.30), and the control group (29.65 days), but the differences were not statistically significant. Comparing groups with and without chronic alcohol exposure, the mean lifespan of the control group chronically exposed to alcohol significantly decreased by 9.51 days (p < 0.05). In GBE treatment groups, mean lifespan significantly decreased by 0.82 days in high-dose set-up (p < 0.05), and significantly increased by 0.39 days in the low-dose set-up (p < 0.05) upon chronic alcohol exposure.
Conclusion
Garcinia binucao extract supplementation ameliorated the observed reduction in lifespan of Drosophila melanogaster chronically exposed to alcohol.

Background:
With the surge of COVID-19 infections, there were concerns about shortage of mechanical ventilator in several countries including the Philippines.
Objective:
To transform a locally made, low-cost, neonatal ventilator into a volume- and pressure-controlled, adult ventilator and to determine its safe use among ventilated, adult patients at the Philippine General Hospital.
Methods:
The modification of the neonatal ventilator (OstreaVent1) to the adult OstreaVent2 was based on the critical need for adult ventilators, in volume or pressure mode, in the Philippines due to the COVID-19 pandemic. The adult ventilator settings were calibrated and tested for two days to check for consistency and tolerance and then submitted to a third party for certification. Once certified, a safety trial of 10 stable adult patients on mechanical ventilator was conducted. The patients were placed on the OstreaVent2 for four hours while ventilator parameters, patient’s vital signs, and arterial blood gases were monitored at baseline, during, and after placement on the OstreaVent2. A poststudy chest radiograph was also done to rule out pulmonary complications, particularly atelectasis and pneumothorax.
Results:
The prototype OstreaVent2 received an FDA Certification for Medical Listing after passing its thirdparty
certification. Ten patients (60% male) recruited in the study had a mean age of 39.1 ± 11.6 years. Half of the patients had a diagnosis of non-COVID-19 pneumonia. During the 4-hour study period, the patients while on the OstreaVent2, had stable ventilator settings and most of the variabilities were within the acceptable tolerances. Vital signs were stable and arterial blood gases were within normal limits. One patient developed alar flaring which was relieved by endotracheal tube suctioning. No patient was withdrawn from the study. One patient who was already transferred out of the ICU subsequently deteriorated and died three days after transfer to the stepdown unit from a non-ventilator related cause.
Conclusion
The new OstreaVent2 is safe to use among adults who need ventilator support. Variabilities in
the ventilator’s performance were within acceptable tolerances. Clinical and blood gas measurements of the patients were stable while on the ventilator.

BACKGROUND
Diabetes Mellitus Type 2 is a significant global health issue with a high prevalence in the Philippines. Managing this condition effectively is crucial, and digital technologies, particularly smartphone (mHealth) applications, have emerged as a potential tool in diabetes self-management.
OBJECTIVEThis study evaluated the effectiveness of smartphone (mHealth) application use in achieving glycemic control among adults with Type 2 Diabetes Mellitus, focusing on HbA1c levels and medication adherence.
METHODThis systematic review and meta-analysis, adhering to PRISMA guidelines, analyzed randomized controlled trials from databases like PubMed and Embase, comparing interventions using mHealth applications with standard care. The primary measures were HbA1c levels and medication adherence.
RESULTSTen studies involving 20,984 participants were included in the meta-analysis. Using mHealth applications led to an average HbA1c reduction of 0.36%, indicating improved glycemic control. There was considerable heterogeneity (I2 = 91%) because of the clinical and methodological diversity of the included studies. Subgroup analysis showed that the younger and older age groups, shorter and longer T2DM duration, and lower and higher HbA1c baseline benefited from its use. Sensitivity analysis still showed high heterogeneity (95%-97%), reflecting clinical diversity. A narrative analysis of two studies highlighted the utility of mHealth applications in tracking diet, physical activity, and vital stats, aiding medication adherence through reminders and data sharing with healthcare providers.
CONCLUSION/RECOMMENDATIONSThis systematic review and meta-analysis showed the effectiveness of mHealth application use in achieving glycemic control among adults with Type 2 Diabetes Mellitus by improving HbA1c levels and medication adherence. Integrating mHealth applications as adjuncts in family and community medicine as part of personalized care for managing type 2 diabetes in the Philippines can help achieve glycemic control and medication adherence. Future studies should focus on longitudinal assessments, exploring cultural and linguistic factors in the Filipino context to optimize diabetes care within this specialized medical framework.

OBJECTIVES
This quality improvement study aimed to explore the viability of a learning pedagogy for medical students, the interactive journal club (IJC), in stimulating active learning and engagement among learners. The study intends to explore the benefits provided by the IJC when compared to traditional learning methods (e.g., traditional journal clubs). It attempts to highlight the importance of didactics which focus on active learning and interactive engagement between learners.
The IJC was implemented as a course requirement in HI 201: Health Informatics, a midyear elective course at the College of Medicine, University of the Philippines Manila. A class of MD-PhD (Molecular Medicine) students was divided into two separate groups: the designated leaders who presented the article and moderated the discussion, and the audience who did not read the article beforehand yet were involved in its critical analysis. The IJC was conducted twice in two different sections of MD-PhD (Molecular Medicine) students, across two different midyear terms, Midyear Term 2021, and Midyear Term 2022. Reflection papers were collected and the responses through this requirement were collated before the primary takeaways were extrapolated. A survey was also sent out to the students of each class to itemize the consolidated feedback of students on the proposed didactic.
The overall process of IJC was deemed both exciting and stimulating. The learning pedagogy provided an alternative platform for active learning, fostering a student-centered approach that placed a heavy emphasis on critical thinking. One major challenge identified in the implementation of the educational design was the heavy reliance on student participation which was identified to, at times, be a difficult factor to overcome. In order to improve its implementation, expectations may be set at the beginning and assessed at the end of the session. In addition, a pre- and post-questionnaire may be given to assess the perceived usefulness of this new method for qualitative comparison.
Interactive and student-centered modes of learning are empirical for the improvement of literature appraisal, journal presentation, and evidence-based critical thinking among medical students. IJCs may be utilized as an alternative and effective learning strategy in teaching pertinent skills expected of a proper physician. When compared to traditional pedagogies, IJCs provide a platform for deeper learning and enable the achievement of learning outcomes, with learner engagement as the focal point. Future attempts at executing IJCs may consider the implementation of learning outcomes setting, and the use of pre- and post-IJC surveys to assess the effectiveness of the modality.

BACKGROUND AND OBJECTIVES
The Department of Clinical Epidemiology (DCE) of the University of the Philippines Manila is the only higher education institution in the Philippines offering graduate studies in clinical epidemiology. The Master of Science Epidemiology (Clinical Epidemiology) was first offered in 1992, while the Diploma in Epidemiology (Clinical Epidemiology) was offered in 1998. While the courses of the programs are continuously updated based on students’ feedback and advances on topics covered, the point of view of the students and alumni on the program as a whole has not been done. This study aimed to determine 1) self-reported current positions and affiliations, work areas where clinical epidemiology (CE) training is useful, and skills gained from CE training; 2) research studies completed and deemed by respondents to have considerable impact; and 3) strengths, weaknesses, and areas of improvement of the DCE graduate programs.
METHODSThis is an online survey of students and alumni of the DCE graduate programs. We sent email invites to all 287 students and alumni. We collected data on their profession, institutional affiliations, positions, skills gained from their training, areas of clinical epidemiology applications, important research involvement, reasons for recommending or not recommending the programs, and how the graduate programs can be improved. Responses were summarized by frequencies and percentages. An analyst performed qualitative content analysis (QCA) to generate strengths and weaknesses of the program. We validated the results of the QCA through 1) presentation to the research team, 2) sending the survey report to study participants and other students and alumni for feedback, and 3) presentation to the DCE faculty and staff.
RESULTSWe received 159 responses (55.4% of the total study population)—145 (91.2%) were from the MSc program and 11 (6.9%) were from the Diploma program. Majority of the respondents were physicians (93.7%), had hospital affiliations (81.8%), and were affiliated with the academe (61%). Majority of the respondents used clinical epidemiology in their research endeavors (87.4%), clinical practice (85.5%), and teaching (78%). Majority (93.1%) would recommend the program they have taken. Eleven (6.9%) respondents were hesitant due to the possible mismatch with the students’ career path, challenging thesis work, and potential conflicting personal responsibilities. Several strengths of the programs were identified, including excellent and well-implemented programs, supportive faculty and staff, and relevant course work. While completing the course work had not been a problem in general, the main challenge encountered by students is the completion of their thesis, leading to a low graduation rate in the Master of Science program. Suggestions to improve the Master of Science and Diploma programs include 1) Improvement in program implementation, including thesis policies and support, smoother transition from Diploma to MSc Program and vice-versa, and implementation of a blended learning platform; 2) Curricular improvements such as wider choices for electives and tracking towards specialty areas; 3) Innovations in conduct of courses; and 4) Personnel and infrastructure development.
CONCLUSIONThis survey reiterated the importance of clinical epidemiology graduate programs in research capacity building of health care professionals. Students and alumni occupied diverse positions in academic, research, clinical, and pharmaceutical setting, and majority accomplished research studies with considerable impact. A major challenge leading to a low graduation rate in the Master of Science program is the completion of thesis work. The survey identified several initiatives towards continuous quality improvement of clinical epidemiology programs, including improvement of thesis policies and support, updating the curriculum content and materials, increasing allotment of hours for hands-on activities, exploring possibilities of offering electives in partnership with other institutions, offering a blended learning platform, maintaining an efficient administrative support for students, and continuing education for alumni. Strong institutional support for personnel and infrastructure development is essential for these initiatives to succeed.

OBJECTIVE
This study compared the demographics, clinical profile, treatment, and outcomes of retinoblastoma patients seen at medical institutions in the Philippines between two time periods: 2010 to 2015 and 2016 to 2020.
METHODSThis was a multicenter, analytical, cohort study using review of medical charts and databases of retinoblastoma patients seen in 11 medical institutions from 2010 to 2020.
RESULTSThere were 636 patients (821 eyes) included in this study: 330 patients were seen in 2010 to 2015 while 306 in 2016 to 2020. More cases per annum were seen in the latter timeline. The number of patients with unilateral disease was not significantly different between the two time periods (p=0.51). Age at onset of symptom, age at initial consultation, and delay in consult were also not significantly different between the two time periods (p > 0.05). Patients had significantly different distributions of intraocular grades (p < 0.0001) and systemic staging (p < 0.0001) between the two time periods. Enucleation was the most common surgical treatment performed in both timelines. There was significant difference in the status of patients based on the need for systemic chemotherapy (p < 0.01). There was significant difference in outcome between the two time periods, including the proportions of living and deceased patients.
CONCLUSIONThis study compared the most comprehensive data on retinoblastoma patients in the country. There was no improvement in early health seeking behavior based on similar age at initial consult and delay in consult. Enucleation remained the most common treatment mode as opposed to chemotherapy due to similar percentage of patients with unilateral disease, an indication for enucleation rather than chemotherapy.

Executive Summary
This Clinical Practice Guideline for the Periodic Health Examination (Pediatric Immunization) is an output from the joint
undertaking of the Department of Health and National Institutes of Health-Institute of Clinical Epidemiology.
This clinical practice guideline is a systematic synthesis of scientific evidence on immunization for the prevention of human
papilloma virus (HPV) infection, influenza, typhoid fever, Japanese encephalitis, poliomyelitis, meningococcal infection, and Hepatitis
A in the pediatric population. The CPG provides nine (9) recommendations on prioritized questions regarding the relevant vaccines
for preventing these seven (7) diseases.
Recommendations are based on the appraisal of the best available evidence on each of the eight identified clinical
questions. The CPG is intended to be used by general practitioners and specialists in the primary care setting, policy makers,
employers and administrators, allied health practitioners and even patients. The guideline development process followed the widely
accepted Grading of Recommendations, Assessment, Development, and Evaluation or the GRADE approach including GRADE
Adolopment, a systematic process of adapting evidence summaries and the GRADE Evidence to Decision (EtD) framework. 1,2 It
includes 1) identification of critical questions and critical outcomes, 2) retrieval of current evidence, 3) assessment and synthesis of
the evidence base for these critical questions, 4) formulation of draft recommendations, 5) convening of a multi-sectoral stakeholder
panel to discuss values and preferences and assess the strength of the recommendations, and 6) planning for dissemination,
implementation, impact evaluation and updating.
The recommendations in this CPG shall hold and will be updated after 3 years or when new evidence arise.
