Preterm birth accounts to 35 % of deaths in a year. Twin gestation, around 7.2 per 1000 births in the Philippines, is a known risk factor that increases likelihood of preterm birth compared to singletons. Most studies that addresses preterm births are focused on singleton pregnancies. There have been no established recommendations to control preterm labor in twin pregnancies. Pessary insertion is among these recommendations. There are no reported cases of pessary insertion to control preterm birth among twins in the Philippines. This study presents a case of twin gestation in preterm labor and no functional cervix on transvaginal ultrasound. Hodge pessary was inserted at 28 weeks age of gestation. She delivered at 36 weeks to live baby girls, both 2,200 grams and were directly roomed-in. Further studies are recommended to establish stronger evidence supporting pessary use in multiple gestation to improve outcome of neonates.

Acta Medica Philippina 2024;58(11):22-28
Objectives:
This study aimed to determine the clinical outcomes of ultra high-risk gestational trophoblastic neoplasia (GTN) patients managed with and without induction chemotherapy in the Division of Trophoblastic Diseases, Department of Obstetrics and Gynecology, Philippine General Hospital.
Methods:
Clinical and demographic data were collected retrospectively from ultra high-risk GTN patients admitted in the Division of Trophoblastic Diseases, Department of Obstetrics and Gynecology, Philippine General Hospital from January 2015 to December 2021. Rate of remission and early death of those who received induction chemotherapy were compared to those who did not.
Results:
A total of 21 patients with ultra high-risk GTN were included in the study, nine of whom underwent induction chemotherapy while 12 had no induction chemotherapy and was given the standard EMACO regimen. There was no significant difference in the rate of early death as well as the rate and time to achieve remission between those who received induction chemotherapy compared to those who were immediately started on EMACO.
Conclusion
A firm conclusion cannot be drawn from the results considering the small population included in the study. Further studies with larger sample size and prospective study design are recommended.

3.Metformin as an adjunct to progestin therapy in endometrial hyperplasia and early-stage endometrial cancer: A systematic review and meta-analysis of randomized controlled trials.

Background:
Metformin has been studied for its anti-proliferative effects on endometrial cells, and it is hypothesized to have a synergistic effect with progestin therapy in suppressing endometrial cell proliferation. This systematic review and meta-analysis aimed to determine the efficacy of adjunctive metformin in the clinical regression of endometrial hyperplasia and early-stage endometrial carcinoma.
Methodology:
This meta-analysis followed the Cochrane methodology and adhered to the PRISMA 2020 guidelines. Randomized controlled trials (RCTs) were included if they enrolled reproductive-aged women with endometrial hyperplasia (with and without atypia) and endometrial carcinoma who were treated with progestin and metformin. The primary outcome was the complete response rate at 12-16 weeks, and secondary outcomes included relapse rate, clinical pregnancy rate, and live birth rate. Odds ratios (ORs) and 95% confidence intervals (CIs) were used for dichotomous data.
Results:
Six RCTs were included. The addition of metformin to progestin therapy may increase the complete response rate of endometrial hyperplasia without atypia (OR 5.12, 95% CI 1.17 to 22.41; n=102) and live birth rates (OR 2.51, 95% CI 1.34 to 4.69; n=188) compared to progestin therapy alone, but the certainty of the evidence is low. Metformin did not have a significant effect on the clinical response of endometrial hyperplasia with atypia and endometrial carcinoma, relapse rates, and clinical pregnancy rates.
Conclusion
Current evidence is uncertain on the potential benefit of metformin with progestin in endometrial hyperplasia and carcinoma. Future high-quality randomized controlled trials with larger sample sizes and longer follow-up periods are needed to support practice recommendations.

4.Preterm birth research in Southeast Asia and its association with socioeconomic determinants and burden of disease: A bibliometric analysis.

Acta Medica Philippina 2024;58(11):72-80
Objective:
The aim of this study was to assess research productivity on preterm birth (PTB) in Southeast Asian (SEA) countries and its correlation with socioeconomic characteristics and burden of disease.
Methods:
A systematic review of preterm birth publications by SEA authors indexed in Scopus, PubMed, ClinicalTrials. gov, and Cochrane was done. Case reports, cohorts, control trials, reviews and cost analysis studies done by SEA researches involving pathophysiology, diagnosis, management, and complications of preterm birth was included in the study while published letters to editors were excluded. The correlation of bibliometric indices, namely Scopus citations, and PlumX metrics indices (citations, usage, captures, mentions, and social media), with socioeconomic status and burden of preterm birth in SEA countries were analyzed by computing for the correlation coefficient (r) and p-value at an alpha of 0.05.
Results:
Thailand had the highest number of publications and the highest count across all bibliometric indices among all countries in SEA. The percent gross domestic product (GDP) per capita allotted for research and development (R & D) had direct correlation with publications and captures while crude birth rates had indirect correlation with publications, citations, and captures. Neonatal mortality had indirect correlation with publications and captures.
Conclusion
Support for research and development is essential to increase research productivity in SEA, which in turn may help in finding solutions to decrease the rate of preterm birth in the region.

Acta Medica Philippina 2025;59(Early Access 2025):1-8
BACKGROUND AND OBJECTIVE
Proper documentation of patient safety events is important to be able to provide changes that can prevent events from occurring again. The Philippine General Hospital launched an online platform for reporting patient safety events in 2017. This paper aimed to describe the patient safety events, initial response to the event, and preventive actions done in the institution.
METHODSThis is a retrospective descriptive study of patient safety event records from August 2017 to April 2022. General data of the patients, details surrounding the events, response to the event, and preventive measures done after the event were documented. Descriptive analysis was performed.
RESULTSThere was a total of 625 events reported with 525 total unique reports. There was an increased rate of patient safety event reports from 2021 to 2022. The average rate was 23.8 and 25.7 reports per month, respectively. Most reports were for in-patient cases and were type 3 preventable adverse events. The general initial response of healthcare personnel to the adverse events is to provide the appropriate clinical care. Preventive measures include re-orientation and event specific actions.
CONCLUSIONDocumentation is crucial for patient safety events to provide solutions and prevent reoccurrence of these events that can cause harm to patients.
