BACKGROUND AND OBJECTIVE

Accurately diagnosing bacterial meningitis and ventriculitis in children is challenging due to nonspecific symptoms and the lack of specificity in conventional CSF parameters. Cerebrospinal fluid (CSF) procalcitonin (PCT) is a promising diagnostic marker but studies on its utility in children are lacking. We aimed to assess the diagnostic value of CSF procalcitonin for bacterial meningitis and ventriculitis in children and establish a clinically relevant cut-off level.

A total of 131 patients were included in the study, and the CSF PCT levels were measured in two groups. Group 1 comprised of patients with bacterial meningitis and ventriculitis (n=21), while Group 2 consisted of patients with tuberculous meningitis, fungal meningitis, viral encephalitis, autoimmune encephalitis, central nervous system (CNS) leukemia, and non-infectious or inflammatory CNS conditions (n=110).

CSF PCT demonstrated an area under the curve of 96.57% in the receiver operating characteristic analysis. With a cut-off of 0.19 ng/mL, it achieved high sensitivity (90.48%) and specificity (91.82%), making it an excellent test for distinguishing between bacterial meningitis and ventriculitis from control diseases.

CSF procalcitonin is highly effective in distinguishing pediatric bacterial meningitis and ventriculitis. Especially in clinical scenarios where the conventional laboratory tests are inconclusive, it can complement clinical assessment to diagnose CNS infections accurately and guide prudent antibiotic use.

Objectives: To compare the vector analysis, visual, and refractive outcomes of femtosecond-assisted laser insitu keratomileusis (LASIK) and small incision lenticule extraction (SMILE) among myopic patients with moderate myopic astigmatism. Methods: This was a single-center, retrospective, cohort study that compared eyes that underwent femtosecond LASIK or SMILE for the correction of myopia and astigmatism of 0.75 to 3.0 diopters. Vector analysis and standard graphs for reporting visual and refractive outcomes were utilized for analysis. Results: There were 82 femtosecond LASIK-treated eyes and 80 SMILE-treated eyes with similar preoperative characteristics except for slightly higher mean preoperative sphere refraction in the SMILE group (-4.2±2.4 D vs -4.9±1.6 D, p=0.03). At 3 months, femtosecond LASIK group had better mean uncorrected distance visual acuity (UDVA) (LogMAR 0.006±0.06 vs 0.06±0.09, p=0.00) and had more eyes achieving postoperative UDVA of 20/20 or better (88% versus 56%). Although there were similar postoperative spherical equivalents, residual astigmatism was higher in the SMILE group (0.11±0.22 D vs 0.32±0.30 D, p=0.00). Vector analyses showed significantly better outcomes for femtosecond LASIK than for SMILE in terms of difference vector (DV), index of success (IOS), torque, and flattening index (FI). A trend for undercorrection for higher astigmatism was seen in both groups that was greater in the SMILE group. Both groups showed high safety with the majority of eyes showing postoperative corrected distance VA (CDVA) within 1 line of preoperative CDVA (98.8% versus 91.2%). Conclusion Although femtosecond LASIK and SMILE have similar predictability at 3 months, femtosecond LASIK has relatively better efficacy and superior astigmatic outcomes than SMILE for the correction of moderate myopic astigmatism.

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 Hypertension is the most common risk factor for cardiovascular disease in the Philippines. Despite the availability of antihypertensive medications that are effective, safe, and tolerated by Filipino patients, the numbers of uncontrolled hypertensives are still increasing. Several factors play in the poor control of blood pressure, particularly resistant hypertension and hyperactive sympathetic nervous system. Renal denervation therapy is a novel device that has been shown to lower blood pressure in patients with resistant and difficult-to-treat hypertension and is deemed safe in clinical trials. A Philippine Working Group composed of specialists in cardiology, hypertension, vascular surgery, and clinical epidemiology has come up with consensus statements in identifying patients who will benefit from the procedure. Locally, there is a need to have hypertension centers treating uncontrolled and resistant hypertension and offer renal denervation therapy to appropriate Filipino patients.

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.

This 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.

There 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.

This 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.

Purpose: We compared the incidence of venous thromboembolism (VTE) among Asian populations with localized colorectal cancer undergoing curative resection with and without the use of pharmacological thromboprophylaxis (PTP). Methods: A comprehensive literature search was undertaken to identify relevant studies published from January 1, 1980 to February 28, 2022. The inclusion criteria were patients who underwent primary tumor resection for localized nonmetastatic colorectal cancer; an Asian population or studies conducted in an Asian country; randomized controlled trials, case-control studies, or cohort studies; and the incidence of symptomatic VTE, deep vein thrombosis, and/or pulmonary embolism as the primary study outcomes. Data were pooled using a random-effects model. This study was registered in PROSPERO on October 11, 2020 (No. CRD42020206793). Results: Seven studies (2 randomized controlled trials and 5 observational cohort studies) were included, encompassing 5,302 patients. The overall incidence of VTE was 1.4%. The use of PTP did not significantly reduce overall VTE incidence: 1.1% (95% confidence interval [CI], 0%–3.1%) versus 1.9% (95% CI, 0.3%–4.4%; P = 0.55). Similarly, PTP was not associated with significantly lower rates of symptomatic VTE, proximal deep vein thrombosis, or pulmonary embolism. Conclusion The benefit of PTP in reducing VTE incidence among Asian patients undergoing curative resection for localized colorectal cancer has not been clearly established. The decision to administer PTP should be evaluated on a case-bycase basis and with consideration of associated bleeding risks.

This study aims to assess the quality and performance of predictive models for colorectal cancer liver metastasis (CRCLM). A systematic review was performed to identify relevant studies from various databases. Studies that described or validated predictive models for CRCLM were included. The methodological quality of the predictive models was assessed. Model performance was evaluated by the reported area under the receiver operating characteristic curve (AUC). Of the 117 articles screened, seven studies comprising 14 predictive models were included. The distribution of included predictive models was as follows: radiomics (n = 3), logistic regression (n = 3), Cox regression (n = 2), nomogram (n = 3), support vector machine (SVM, n = 2), random forest (n = 2), and convolutional neural network (CNN, n = 2). Age, sex, carcinoembryonic antigen, and tumor staging (T and N stage) were the most frequently used clinicopathological predictors for CRCLM. The mean AUCs ranged from 0.697 to 0.870, with 86% of the models demonstrating clear discriminative ability (AUC > 0.70). A hybrid approach combining clinical and radiomic features with SVM provided the best performance, achieving an AUC of 0.870. The overall risk of bias was identified as high in 71% of the included studies. This review highlights the potential of predictive modeling to accurately predict the occurrence of CRCLM. Integrating clinicopathological and radiomic features with machine learning algorithms demonstrates superior predictive capabilities.

INTRODUCTION: Three doses of SARS-CoV-2 mRNA vaccines have been recommended for cancer patients to reduce the risk of severe disease. Anti-neoplastic treatment, such as chemotherapy, may affect long-term vaccine immunogenicity. METHOD: Patients with solid or haematological cancer were recruited from 2 hospitals between July 2021 and March 2022. Humoral response was evaluated using GenScript cPASS surrogate virus neutralisation assays. Clinical outcomes were obtained from medical records and national mandatory-reporting databases. RESULTS: A total of 273 patients were recruited, with 40 having haematological malignancies and the rest solid tumours. Among the participants, 204 (74.7%) were receiving active cancer therapy, including 98 (35.9%) undergoing systemic chemotherapy and the rest targeted therapy or immunotherapy. All patients were seronegative at baseline. Seroconversion rates after receiving 1, 2 and 3 doses of SARS-CoV-2 mRNA vaccination were 35.2%, 79.4% and 92.4%, respectively. After 3 doses, patients on active treatment for haematological malignancies had lower antibodies (57.3%±46.2) when compared to patients on immunotherapy (94.1%±9.56, P<0.05) and chemotherapy (92.8%±18.1, P<0.05). SARS-CoV-2 infection was reported in 77 (28.2%) patients, of which 18 were severe. No patient receiving a third dose within 90 days of the second dose experienced severe infection. CONCLUSION This study demonstrates the benefit of early administration of the third dose among cancer patients.

Purpose: This study compared the short- and long-term clinical outcomes of laser hemorrhoidoplasty (LH) vs. conventional hemorrhoidectomy (CH) in patients with grade II/III hemorrhoids. Methods: PubMed/Medline and the Cochrane Library were searched for randomized and nonrandomized studies comparing LH against CH in grade II/III hemorrhoids. The primary outcomes included postoperative use of analgesia, postoperative morbidity (bleeding, urinary retention, pain, thrombosis), and time of return to work/daily activities. Results: Nine studies totaling 661 patients (LH, 336 and CH, 325) were included. The LH group had shorter operative time (P<0.001) and less intraoperative blood loss (P<0.001). Postoperative pain was lower in the LH group, with lower postoperative day 1 (mean difference [MD], –2.09; 95% confidence interval [CI], –3.44 to –0.75; P=0.002) and postoperative day 7 (MD, –3.94; 95% CI, –6.36 to –1.52; P=0.001) visual analogue scores and use of analgesia (risk ratio [RR], 0.59; 95% CI, 0.42–0.81; P=0.001). The risk of postoperative bleeding was also lower in the LH group (RR, 0.18; 95% CI, 0.12– 0.28; P<0.001), with a quicker return to work or daily activities (P=0.002). The 12-month risks of bleeding (P>0.999) and prolapse (P=0.240), and the likelihood of complete resolution at 12 months, were similar (P=0.240). Conclusion LH offers more favorable short-term clinical outcomes than CH, with reduced morbidity and pain and earlier return to work or daily activities. Medium-term symptom recurrence at 12 months was similar. Our results should be verified in future well-designed trials with larger samples.

Background: Intravitreal chemotherapy has been an effective addition in treating vitreous seeding in retinoblastoma. However, it was only in 2020 that it was used in the Philippines. There is no literature on its use in multiple Filipino retinoblastoma patients. Objectives: To describe the clinical course of the four patients who are the first to undergo intravitreal chemotherapy for vitreous seeding of retinoblastoma in the Philippine tertiary hospital. Methods: A case series of four eyes of four patients with retinoblastoma who underwent intravitreous injection of melphalan and topotecan for vitreous seeding at the Department of Ophthalmology and Visual Sciences of a Philippine tertiary hospital. Results: Two eyes, with International Intraocular Retinoblastoma Classification (IIRC) Group C with vitreous seeding, responded well to intravitreous melphalan and topotecan. One eye had recurrent vitreous seeding despite 10 intravitreal injections. One eye with IIRC Group E, did not respond to intravitreous chemotherapy and was eventually enucleated. This is the first case series on the local use of intravitreous chemotherapy in the country for vitreous seeding in retinoblastoma. The control of 50% achieved in this case series is lower than in other series due to longer treatment interval from poor follow-up and the presence of advanced disease. Conclusion The use of intravitreous melphalan and topotecan can be an effective adjuvant for systemic chemotherapy in controlling vitreous seeding in eyes with IIRC Group C. It is not effective in controlling IIRC Group E disease.
