This study aims to determine the prevalence of erectile dysfunction (ED) and identify its associated risk factors among young and middle-aged Filipino male patients diagnosed with diabetes mellitus. This study utilized a cross-sectional design to investigate the prevalence and associated factors of ED among male patients with diabetes. A total of 423 participants were recruited from clinical settings using purposive sampling. Data were collected using structured interviews and medical records, including demographics, comorbidities and laboratory results. Among 423 male diabetic patients, 78% were found to have ED. Patients with ED were significantly older (median: 49.5 versus 42 years, p<0.001), had higher body mass index (BMI), longer diabetes duration and more comorbidities. Univariable logistic regression showed that age (OR: 1.06, p<0.001), diabetes duration (OR: 1.11, p<0.001), hypertension (OR: 1.62, p = 0.042), dyslipidemia (OR: 1.75, p = 0.022), elevated HbA1c (>9.0%; OR: 3.43, p = 0.034) and serum creatinine (OR: 1.01, p = 0.008) were significantly associated with ED. However, none remained significant in the multivariable model. Male Filipino patients with diabetes have a significant burden of ED. Results of the univariable models show that age, duration of diabetes, hypertension, dyslipidemia, HbA1c and serum creatinine are significant individual predictors of ED.

In the Philippines, the rate of sexually transmitted infections (STIs) remains high, and statistics show that the highest prevalence is among individuals between the ages of 15 and 24 years old. Unlike Human Immunodeficiency Virus (HIV), other common STIs, such as gonorrhea, syphilis, HPV and herpes are not well discussed.
A descriptive cross-sectional study was conducted to determine the knowledge, awareness and misconceptions of STIs and their practices among men and women aged 15-24 in Sampaloc, Manila. Convenience sampling was conducted among 15- to 24-year-old residents from Barangay 466, excluding healthcare professionals. Sets of questions were adapted from other knowledge, attitudes and practices (KAP) research studies and underwent cross-cultural validation. Questions were also translated and validated into the Filipino language. Data gathering was conducted using self-administered surveys disseminated through online posting and in-community, as well as face-to-face recruitment.
Among the 104 respondents, HIV remained the most recognized STI (99%), while less than half were aware that chlamydia and hepatitis B are STIs. The most common misconception about STI transmission includes the sharing of food and drinks. In terms of prevention, more than half of the participants believed that oral contraceptive pills can prevent STIs. With regards to attitude, 43.3% of the participants disagreed that watching/reading pornographic materials can contribute to risky sexual practices. Among sexually active participants, 19% do not use condoms, and 65% of them do not get tested annually.
In conclusion, the findings from this study reveal a concerning gap in KAP related to STIs among participants aged 15-24 Filipinos. It is recommended that efforts should be directed towards targeted education campaigns and interventions to empower young individuals with accurate information and foster a responsible approach to sexual health.

OBJECTIVE:
To explore the genotype-phenotype relationship in a child with Opitz G/BBB syndrome (OS) with mild clinical phenotype.
METHODS:
A child with motor developmental delay as the initial symptom admitted to Xi'an Children's Hospital on June 10, 2021 was selected for this study. Clinical data were collected, and peripheral blood samples were obtained from the child and his mother. Whole exome sequencing (WES) was performed to identify genetic variant in the child. Candidate variant were verified by Sanger sequencing to assess inheritance patterns and pathogenicity. Real-time fluorescence quantitative PCR (RT-qPCR) and Western blot (WB) analyses were conducted to evaluate the effects of the variant on mRNA and protein expression, respectively, using recombinant expression plasmids generated in vitro. This study was approved by the Medical Ethics Committee of Xi'an Children's Hospital (Ethics No. 20240045).
RESULTS:
The child, a 9-month-and-7-day-old boy, presented with a low nasal bridge, hypertelorism, and difficulty sitting independently. Echocardiography revealed an atrial septal defect. WES identified a homozygous variant in the MIDI gene, c.1483C>T (p.R495X), which was confirmed by Sanger sequencing and found to be inherited from the mother.Recombinant expression plasmids were successfully constructed. RT-qPCR analysis showed that the variant significantly reduced MIDI gene mRNA expression, while WB results indicated that the variant led to the production of a truncated protein.
CONCLUSION
The mild clinical phenotype of OS in this child may be attributed to the mRNA degradation escape mechanism induced by the nonsense variant c.1483C>T (p.R495X) in the MIDI gene. These findings provide valuable diagnostic insights for this pedigree and contribute to the understanding of the genotype-phenotype correlation in OS.

INTRODUCTION AND OBJECTIVE
The increasing demand for cost-effective surgical techniques has driven innovations in robotic-assisted radical prostatectomy (RARP). While single-port robotic surgery reduces invasiveness and improves cosmesis, its widespread use is limited by high costs and technical constraints. This study evaluates the safety, feasibility and cost-effectiveness of extraperitoneal single-port robotic-assisted radical prostatectomy (espRARP) using a modified Da Vinci Si HD system, employing a wound protector and surgical glove as a low-cost multi-channel laparoscopic port.
METHODSTen patients with localized prostate cancer underwent espRARP using a three-arm Da Vinci Si system and side docking to enhance instrument access. A homemade multi-channel port was constructed using an Alexis® wound protector and surgical gloves. Perioperative outcomes—including operative time, blood loss, complications and oncologic results were analyzed descriptively.
RESULTSAll cases were completed without conversion to open surgery. The mean operative time was 215.8 minutes with an estimated blood loss of 200 mL. No positive surgical margins were recorded, and 20% of patients exhibited pathological upgrading. The average hospital stay was 3.4 days. One patient developed a Clavien–Dindo II complication; no major complications occurred
LIMITATIONSThis pilot study is limited by its small sample size (n = 10), single-surgeon, single institution design, short follow-up period, and absence of functional outcome assessment. Only descriptive analysis was performed without statistical comparison.
CONCLUSIONThe modified espRARP technique using a low-cost glove-port and three-arm Da Vinci Si system is safe, feasible and cost-efficient. Comparable perioperative and oncologic outcomes to conventional multi-port and proprietary single-port systems were achieved at a fraction of the cost. This approach provides a practical and accessible alternative for robotic prostatectomy in resource-limited healthcare settings.

OBJECTIVES
To create a pilot urologic malignancy registry using demographic and clinical data of a cohort of patients newly diagnosed to have urologic malignancies in the year 2021.
METHODSThis was a prospective cohort study conducted in four study sites: National Kidney and Transplant Institute, East Avenue Medical Center, UP-Philippine General Hospital and Batangas Medical Center
RESULTSA total of 243 patients with newly diagnosed urologic cancers were enrolled. The median age was 61 years, with a wide range of 1 to 87 years. Most of the patients (81.47%) were male, while there were 45 females (18.52%) who had either urinary bladder, kidney or upper urothelial cancer. The most common type of malignancy was prostate cancer (34.57%), followed by kidney cancer (30.04%) and urinary bladder cancer (24.69%), consistent with the currently observed worldwide incidence. There were also 3 patients (1.23%) noted with multiple primaries. More than half of the patients (63.37%) received surgery as active treatment. After the two-year follow-up period, thirteen patients (5.35%) developed progressive disease, and 14 patients (5.76%) died.
CONCLUSIONThis urologic cancer registry represents the first multi-center, investigator-initiated epidemiologic study of its kind in the Philippines. As a proof-of-concept (POC) project, it demonstrates the feasibility of establishing a national database capturing baseline data on the country’s most common urologic malignancies.

Journal of the Philippine Dermatological Society 2025;34(2):74-77
Bowenoid papulosis (BP) is an uncommon yet clinically significant human papillomavirus (HPV)-associated condition that exhibits features of both condyloma acuminata and carcinoma insitu. We report the case of a 24-year-old Filipino male with multiple pruritic, pigmented penile lesions of 5 months’ duration, confirmed histologically as BP. This case underscores the importance of recognizing HPV-related lesions early and initiating appropriate treatment, not only to prevent progression to malignancy but also to limit transmission. The report also highlights the relevance of offering HPV vaccination, particularly to males, and the critical need for screening for other sexually transmitted infections, especially in light of the growing human immunodeficiency virus epidemic in the Philippines, underscoring that the condition itself may be sexually transmitted in nature.

OBJECTIVES:
To identify immunosuppressive neutrophil subsets in patients with prostate cancer (PCa) and construct a risk prediction model for prognosis and immunotherapy response of the patients based on these neutrophil subsets.
METHODS:
Single-cell and transcriptome data from PCa patients were collected from the Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA). Neutrophil subsets in PCa were identified through unsupervised clustering, and their biological functions and effects on immune regulation were analyzed by functional enrichment, cell interaction, and pseudo-time series analyses. Lasso-Cox regression was utilized to construct a prognostic risk model based on the immunosuppressive neutrophil subsets, and survival analysis and ROC curve analysis were used to compare the prognosis of PCa patients with high and low risks stratified using this model. The relationship of the prognostic risk model with PCa immune infiltration and immune response was evaluated using CIBERSORT and TIDE scores.
RESULTS:
PCa tissues showed a significantly greater proportion of infiltrating neutrophils than the adjacent normal tissues (P<0.05). PCa-associated neutrophils could be clustered into two independent cell subsets: Neu_1 and Neu_2. Neu_2 cells exhibited highly enriched immunoregulatory functions and were highly differentiated and mature, with upregulated immunosuppressive cytokines such as TGFB1, ITGB2, and LGALS3. Based on the genetic characteristics of Neu_2 cell subsets, the prognostic risk model was constructed. The patients in the high-risk group identified by the model had a shorter biochemical recurrence time (P<0.05) and a higher proportion of Tregs and M2-TAMs cell infiltration (P<0.05) with a higher risk of immune rejection and poorer immune response scores.
CONCLUSIONS
PCa-associated neutrophils are highly heterogeneous. The prognostic risk model constructed based on the immunosuppressive neutrophil Neu_2 subset can effectively predict both the survival outcomes and immune response of PCa patients.

OBJECTIVES:
To develop risk prediction models for postoperative hypothermia after transurethral holmium laser enucleation of the prostate (HoLEP) using machine learning algorithms.
METHODS:
We retrospectively analyzed the clinical data of 403 patients from our center (283 patients in the training set and 120in the internal validation set) and 120 patients from Weifang People's Hospital (as the external validation set). The risk prediction models were built using logistic regression, decision tree and support vector machine (SVM), and model performance was evaluated in terms of accuracy, recall, precision, F1 score and AUC.
RESULTS:
Operation duration, prostate weight, intraoperative irrigation volume, and being underweight were identified as the predictors of postoperative hypothermia following HoLEP. Among the 3 algorithms, SVM showed the best precision rate and accuracy in all the 3 data sets and the best area under the ROC (AUC) in the training set and validation set, followed by logistic regression, which had a similar AUC in the two data sets. SVM outperformed logistic regression and decision tree models in the validation set in precision, accuracy, recall, F1 score, and AUC, and performed well in the external validation set with better precision rate and accuracy than logistic regression and decision tree models but slightly lower recall rate, F1 index, and AUC value than the decision tree model. SVM outperformed logistic regression and decision tree models in precision, accuracy, F1 score, and AUC in the training set, but had slightly lower recall rate than the decision tree.
CONCLUSIONS
Among the 3 models, SVM has the best performance and generalizability for predicting post-HoLEP hypothermia risk to provide support for clinical decisions.

Xiaoaiping (XAP) Injection demonstrates the anti-prostate cancer (PCa) effects, yet the underlying mechanism remains unclear. This study aims to investigate the impact of XAP on PCa and elucidate its mechanism of action. PCa cell proliferation was evaluated using a cell counting kit-8 (CCK-8) assay. Cell apoptosis was assessed through Hoechst staining and Western blotting assays. Proteomics technology was employed to identify key molecules and significant signaling pathways modulated by XAP in PCa cells. To further validate potential key genes and important pathways, a series of assays were conducted, including acridine orange (AO) staining, transmission electron microscopy, and immunofluorescence assays. The molecular mechanism of XAP against PCa in vivo was examined using a PC3 xenograft mouse model. Results demonstrated that XAP significantly inhibited cell proliferation in multiple PCa cell lines. In C4-2 and prostate cancer cell line-3 (PC3) cells, XAP induced cellular apoptosis, evidenced by reduced B-cell lymphoma 2 (Bcl-2) levels and elevated Bcl-2-associated X (Bax) levels. Proteomic, immunofluorescence, and quantitative reverse transcription-polymerase chain reaction (qRT-PCR) investigations revealed a strong correlation between forkhead box O3a (FoxO3a) autophagic degradation and the anti-PCa action of XAP. XAP hindered autophagy by reducing the expression levels of autophagy-related protein 5 (Atg5)/autophagy-related protein 12 (Atg12) and enhancing FoxO3a expression and nuclear translocation. Furthermore, XAP exhibited potent anti-PCa action in PC3 xenograft mice and triggered FoxO3a nuclear translocation in tumor tissue. These findings suggest that XAP induces PCa apoptosis via inhibition of FoxO3a autophagic degradation, potentially offering a novel perspective on XAP injection as an effective anticancer therapy for PCa.
