Objective: This study aimed to demonstrate the benefits of using SaTScan (Boston, MA, USA), a cluster-detection software programme, and whole genome sequencing to investigate a suspected outbreak of Serratia marcescens infections in a tertiary government hospital in the southern Philippines. The hospital is part of the national Antimicrobial Resistance Surveillance Program’s network of sentinel sites. Methods: The investigation followed national outbreak investigation protocols. In May 2022, when evaluation of daily hospital laboratory census data revealed an increase in the number of Serratia species in the hospital, an alert was triggered. A concurrent, routine SaTScan analysis of the hospital’s surveillance data by the Antimicrobial Resistance Surveillance Reference Laboratory confirmed a cluster of cases. The Reference Laboratory requested isolates from clinical specimens from the hospital for confirmation of bacterial identification, antimicrobial susceptibility testing and whole genome sequencing. Results: Six isolates were submitted for genomic analysis, two of which were from the identified cluster. Although originally identified as S. marcescens, five of the isolates were subsequently confirmed as S. sarumanii. Phylogenetic analysis showed that the two isolates from the cluster were closely related and belonged to the same clade, which may suggest a common source. Three antimicrobial resistance genes were identified, but their phenotypic expression was limited, with one isolate exhibiting resistance mechanisms. Discussion: This study highlighted the utility of SaTScan for the early detection of potential disease outbreaks. The use of whole genome sequencing enhanced the investigation by enabling the analysis of potential transmission pathways at the genetic level, identification of the outbreak source and the detection of novel species.

Objective: To investigate COVID-19 mortality in Philippine provinces from 2020 to 2023. Methods: Crude mortality rate (CMR), age-standardized mortality rate (ASMR) and age-specific mortality rate were computed for 84 areas (82 provinces and 2 cities) using COVID-19 surveillance data from the Philippine Department of Health, which captured data about confirmed deaths occurring between 20 January 2020 and 9 May 2023. Provinces were ranked by their ASMR. A correlation analysis was conducted to identify possible predictors of COVID-19 mortality. Among the factors investigated were the incidence of poverty, population density, proportion of the population considered elderly (aged >=65 years), hospital bed density and COVID-19 testing rates. Results: Eight of the 10 provinces that had the highest COVID-19 ASMRs were located in the Luzon island group. The province with the highest ASMR was Benguet in Northern Luzon (207.83 deaths/100 000 population), and the lowest rate was in Tawi-Tawi in Southwestern Mindanao (2.22 deaths/100 000 population). The incidence of poverty was negatively correlated with COVID-19 mortality, while hospital bed density and COVID-19 testing rates were positively correlated with CMRs and ASMRs. Discussion: This analysis provides a starting point for investigating COVID-19 mortality in Philippine provinces. The ranking of provinces by their ASMR is useful for directing future epidemiological investigations and, coupled with the results of the correlation analysis, provides insight into the factors that may have impacted COVID-19 mortality in the Philippines. Our analysis suggests that COVID-19 mortality patterns can partly be explained by the streetlight effect and factors linked to the availability of and access to health care.

BACKGROUND AND OBJECTIVES

The global pandemic caused by Coronavirus Disease 2019 (COVID-19) has affected millions, with growing evidence of the potential role of ocular tissues in viral transmission. At the time of writing, local data regarding the phenomenon was limited. This study investigated external ocular manifestations in patients with COVID-19 at a referral center in the Philippines, examined correlations between demographics, systemic manifestations, and laboratory results with ocular manifestations, and determined their timing relative to systemic symptoms.

METHODS

This single-center, descriptive cross-sectional study was carried out from December 8 to 18, 2020 at the adult COVID-19 wards of the Philippine General Hospital involving 72 participants. Data collection involved relevant clinical history taking and performing gross eye examination. The prevalence of ocular manifestations was described with 95% confidence intervals. Correlations between ocular manifestations and quantitative variables were analyzed with point-biserial correlation, and associations with qualitative variables were tested using chi-square or Fisher’s exact tests.

RESULTS

Among participants, 31.9% presented with ocular manifestations with foreign body sensation as the most prevalent ocular symptom (11.1%) and conjunctival hyperemia as the most prevalent ocular finding (19.4%). The median age of patients with ocular manifestations was 41 years old with a higher prevalence in the male population (73.9%, CI=95%, p=0.001). No significant correlation was observed between presence of external ocular manifestations and the different systemic and ocular co-morbidities as well as with COVID-19 clinical classification. Among those who experienced symptoms, majority (29.2%) of the patients experienced systemic symptoms prior to the onset of ocular symptoms. Ocular complaints may present as the sole manifestation (13.9%). Several laboratory parameters were measured and only temperature and AST levels showed a low positive correlation with the presence of ocular manifestations. 

CONCLUSION

Ocular manifestations occur in roughly one third of patients with COVID-19 based on this study population. With some individuals presenting with ocular signs or symptoms as the initial and sole manifestation, healthcare practitioners must exercise caution and remain vigilant in managing patients who present as such. At the time of writing, this is the first local study investigating the different external ocular manifestations in patients with COVID-19. There is a need to pursue more robust studies and conduct more local investigations which will guide both ophthalmologists and other practitioners in strengthening existing guidelines regarding precautionary practices, clinical diagnosis, and management of COVID-19 patients.

OBJECTIVES

Herbal plants can be an alternative source of therapy especially against hypertension, which is a prevalent burden in the Philippines. This study investigates the phytochemical composition and angiotensin-converting enzyme 1 (ACE-1) inhibitory activity of Mayana (Coleus scutellarioides Benth.) leaf extract, a plant ethnobotanically reported to be used for its potential antihypertensive properties and yet still lacking in in-vitro investigations.

METHODS

Employing a laboratory experimental research design and standard procedures for phytochemical screening and ACE-1 inhibitory assay, the study compares a crude ethanolic dehydrated leaf extract of Mayana with the positive control, Captopril.

RESULTS

Phytochemical screening revealed the presence of flavonoids and phenolic compounds. ACE-1 inhibitory activity of Mayana at 10 μg/mL, 25 μg/mL, 50μg/mL, 100 μg/mL, 500 μg/mL, 1000 μg/mL were 0.00% ± 0.0000, 12.40% ± 2.7094, 18.76% ± 0.7232, 27.31% ± 2.2159, 30.44% ± 1.6022, 40.12% ± 2.4385, respectively. Mayana exhibited an IC50 value of 55.9154 μg/mL compared to Captopril which was 7.7232 μg/mL, indicating potency disparities.

CONCLUSION

Mayana has been shown to contain flavonoids and phenolic compounds that exhibit preliminary anti- hypertensive potential through the inhibition of ACE-1. However, the bioactivity of Mayana is lower when compared with a positive control. As such, more research is needed. Despite that, this research contributes to our under- standing of Mayana as a medicinal plant and its potential contribution to complementary and alternative healthcare, with implications for patient care, community awareness, farmer livelihood, education, and future research.

OBJECTIVE

To compare the sedation practices of adult intubated patients with COVID-19-related Acute Respiratory Distress Syndrome (C-ARDS) and ARDS from other causes, and their impact on clinical outcomes in a tertiary hospital.

METHODS

We performed a retrospective cohort on the sedation practices of adult intubated patients with C-ARDS and non-C-ARDS admitted to the intensive care unit of a tertiary hospital from January 2021 to December 2021. Electronic medical records were reviewed to obtain sedative use, sedative dosages, clinical outcomes, and complications.

RESULTS

Among the 150 included patients, 112 had C-ARDS, and 38 had non-C-ARDS. The C-ARDS group showed a significant difference with the non-C-ARDS group in terms of BMI (24.11 vs. 21.09 kg/m2, p < 0.001), use of higher PEEP (16 vs. 10, p < 0.001), and prone positioning (40.18% vs 2.63%, p < 0.01). In terms of sedation practice, C-ARDS patients targeted deeper RASS scores (p=0.038), with a significantly higher proportion receiving more than one sedative (82.14% vs. 18.42, p < 0.001) than non-C-ARDS patients. Sedation doses for midazolam (78 mg/d vs. 36 mg/d; p=0.01) and propofol (mean 2626±1312.97 mg/d vs. 1742±380.99 mg/d; p=0.007), were significantly higher among C-ARDS versus non-C-ARDS group. Duration of hospitalization (9 vs. 20 days; p < 0.001) and ventilator use (7 vs. 14.50 days; p < 0.001) were significantly shorter in the C-ARDS group, albeit with a high mortality (100% vs. 89.47%; p=0.004). Shock-requiring pressor was significantly associated with multiple sedation use [OR=15.11 (1.52-2032.89); p=0.017] and combination use of benzodiazepine and non-benzodiazepines [OR=11.51 (1.17-1541.91); p=0.034] in the C-ARDS but not the C-ARDS group.

CONCLUSION

Patients with C-ARDS had higher sedation requirements in terms of dosage and number of sedatives. The use of multiple sedatives was significantly associated with shock-requiring pressor. We recommend the development of a sedation protocol to guide sedation practices and monitoring of complications in the critically ill.

BACKGROUND AND OBJECTIVE

Residency satisfaction is an important indicator of training quality and may influence physician well-being and performance. Surgical trainees are generally reported to have lower satisfaction compared to other specialties. This study assessed satisfaction among urology residents in the Philippines and evaluated a structured questionnaire for measuring training experience.

MATERIALS AND METHODS

A cross-sectional survey was conducted among residents in accredited urology programs (2024-2024-5). A 12-domain Likert-scale questionnaire was developed and validated. Internal consistency and test-retest reliability were assessed. Satisfaction scores were analyzed overall and across subgroups.

RESULTS

A total of 106 residents participated. The instrument demonstrated good internal consistency (Cronbach's α = 0.870) and strong test-retest reliability (r = 0.896). Overall satisfaction was high (52.41 5.4/60). Clinical exposure was the highest-rated domain, while work-life balance was the lowest. No significant differences were observed by gender, training year, or institution type. Key areas for improvement were case exposure and academic learning.

CONCLUSION

Urology residents in the Philippines report high overall satisfaction. The validated questionnaire is reliable and useful for assessing multidimensional aspects of residency training. Improvements in case exposure, academic support, and work-life balance may further enhance training quality.

OBJECTIVE

This study aimed to identify the different risk factors for developing sepsis in patients undergoing percutaneous nephrolithotomy

METHODS

This is a case-control study of all patients who underwent percutaneous nephrolithotomy in the National Kidney and Transplant Institute from 2017 to 2021. Demographic, stone characteristics, perioperative data and post-operative parameters were recorded. The association of clinical variables and sepsis was determined using logistic regression analysis.

RESULTS

A total of 536 patients who underwent percutaneous nephrolithotomy were included in the study with 58 of them suffering from sepsis with a prevalence rate of 9.9%. The majority [392 (67.82%)] of the patients were 31-59 years old. Majority of patients suffering from sepsis also belonged to the same age group were predominantly male [33 (56.9%)], mostly diabetic [15 (26.32%)] and hypertensive [14 (24.56%)] and underwent previous PCNL [49 (8.45%)]. Imaging of patients who had sepsis showed staghorn calculi [30 (51.72%)] with mild [20 (34.48%)] and moderate [23 (39.66%)] seen on imaging. Patients who were requiring transfusion post operatively (Grade II Clavien-Dindo Classification) were seen to have sepsis.

CONCLUSION

The following factors are contributory to the development of sepsis: a high Guy's stone score, high degree of obstruction or hydronephrosis, previous stone surgery and a higher volume of blood loss.

BACKGROUND

The benefits of preimplantation genetic testing for aneuploidy (PGT-A) in the advanced maternal age group are unclear.

OBJECTIVE

This study aims to determine whether PGT-A improves pregnancy outcomes.

METHODS

This is a retrospective cohort study of PGT-A outcomes using next generation sequencing for advanced maternal age women undergoing IVF at CARMI from May 2017 to May 2021. Women were grouped by age: those 35-39 and those 40 and above. Pregnancy rate (PR), live birth rate (LBR), and miscarriage rate (MR) were computed per transfer and per cycle and compared with women who underwent single day-5 frozen transfer of a morphologically chosen embryo.

RESULTS

Overall euploid blastocyst rate was 38.5%: 16.9% for 40 and above and 47.6% for 35- 39 group. There were no transfers in 41.4% due to absence of a euploid embryo. PR and LBR per embryo transfer were higher in the PGT-A versus the non-PGT-A group (61.9% vs 24.1% p = < 0.001 and 42.9% vs 19% p = < 0.001). By age, the findings were similar: higher PR and LBR per-embryo transfer in PGT-A versus non-PGT-A in the 35-39 group (58.4% and 29%, p = 0.006 and 42.9% vs 22.6%, p < 0.001 respectively) and 40 and above (71.4% vs 18.5%, p < 0.001 and 53.6% vs 14.8%, p < 0.001 respectively). MR was increased in the PGT-A versus non-PGT-A group, but this may be due to the small number of events in the population.

CONCLUSION

The study suggests an increase in PR and LBR per embryo transfer in advanced maternal age women undergoing PGT-A. A larger sample size is needed to validate the results.

OBJECTIVE

This paper reports a rare presentation of diffuse intraocular inflammation following reversed vaulted multipiece intraocular lens (IOL) implanted in the sulcus of a 7-year-old child.

METHODS

This is a case report.

CASE PRESENTATION

A 7-year-old child presented with persistent posterior pole inflammation and optic disc swelling after an improperly placed multipiece intraocular lens in the sulcus. Comprehensive eye and wholebody evaluations were performed with the aid of optical coherence tomography (OCT), magnetic resonance imaging (MRI) and systemic work-up to rule out other causes of uveitis to definitively diagnose the case. The reverse-vaulted lens was eventually explanted. After 1 week post-explantation, the visual acuity improved markedly to 20/100 with the appropriate spectacle prescription. The patient recovered from the ocular inflammation 8 months postoperatively.

CONCLUSION

This paper reports significant posterior pole inflammation as an uncommon yet potentially visually-disabling consequence of a reverse-vaulted sulcus placement of a multipiece intraocular lens in a child. Careful attention is warranted to ensure proper IOL orientation during implantation, especially in pediatric cataract surgery. Visual rehabilitation is important postoperatively
