Objective: Using semiquantitative risk scoring, this study estimated the probability of ASF transmission in 23 selected provinces. Methods: The factors influencing ASF spread were identified; 10 through a literature review and the positivity for ASF virus (ASFv) of meat samples from an ongoing surveillance study.Secondary data from each sampled province were collected, and the provinces were scored across these factors and classified into one of three risk categories. Results: Six out of 23 provinces were categorized as high-risk due to the high number of ASFv-positive meat samples, backyard pigs, and ASF occurrences. Conversely, four provinces were classified as low-risk due to consistently low scores across all indicators. The difference in the meat contamination level between low- and high-risk provinces emphasizes the importance of including this factor in the ASF spread assessment. Conclusions and Relevance: Risk estimation of ASF transmission must consider meat sample contamination. Active surveillance at local borders can monitor contamination and prevent ASFv sources from entering areas. This approach allows the government to allocate resources and prioritize higher-risk areas.

Objective: In ovarian cancer (OvCa), tumor cell high glucocorticoid receptor (GR) has been associated with poor patient prognosis. In vitro, GR activation inhibits chemotherapyinduced OvCa cell death in association with transcriptional upregulation of genes encoding anti-apoptotic proteins. A recent randomized phase II study demonstrated improvement in progression-free survival (PFS) for heavily pre-treated OvCa patients randomized to receive therapy with a selective GR modulator (SGRM) plus chemotherapy compared to chemotherapy alone. We hypothesized that SGRM therapy would improve carboplatin response in OvCa patient-derived xenograft (PDX). Methods: Six high-grade serous (HGS) OvCa PDX models expressing GR mRNA (NR3C1) and protein were treated with chemotherapy +/− SGRM. Tumor size was measured longitudinally by peritoneal transcutaneous ultrasonography. Results: One of the 6 GR-positive PDX models showed a significant improvement in PFS with the addition of a SGRM. Interestingly, the single model with an improved PFS was least carboplatin sensitive. Possible explanations for the modest SGRM activity include the high carboplatin sensitivity of 5 of the PDX tumors and the potential that SGRMs activate the tumor invasive immune cells in patients (absent from immunocompromised mice). The level of tumor GR protein expression alone appears insufficient for predicting SGRM response. Conclusion The significant improvement in PFS shown in 1 of the 6 models after treatment with a SGRM plus chemotherapy underscores the need to determine predictive biomarkers for SGRM therapy in HGS OvCa and to better identify patient subgroups that are most likely to benefit from adding GR modulation to chemotherapy.

BACKGROUND<p style="text-align: justify;" data-mce-style="text-align: justify;">The Philippines has been significantly affected by the HIV epidemic in the Asia-Pacific region, with a notable increase in new cases over the past decade. Despite efforts to promote HIV testing, access to treatment, and awareness campaigns, progress has been slow, particularly among youths. Tangere, a market research application, conducted surveys during and after the COVID-19 pandemic to assess HIV knowledge among Filipinos.p>OBJECTIVES<p style="text-align: justify;" data-mce-style="text-align: justify;">This study aimed to evaluate changes in HIV awareness among young Filipinos during and after the COVID-19 pandemic using data collected via Tangere’s surveys. Specifically, it sought to analyze demographic characteristics, sources of HIV information, and knowledge regarding HIV transmission, prevention, and stigma.p>METHODS<p style="text-align: justify;" data-mce-style="text-align: justify;">Tangere collaborated with the investigators to develop a questionnaire assessing HIV knowledge among young Filipinos. Surveys were conducted during and after the COVID-19 pandemic, targeting subscribers aged 18-35 years, primarily from the National Capital Region and Luzon area. Data analysis involved calculating frequencies and percentages to summarize demographic characteristics and HIV knowledge. An Independent-Samples Proportions procedure was used to compare HIV knowledge during and after the pandemic.p>RESULTS<p style="text-align: justify;" data-mce-style="text-align: justify;">The survey revealed that while respondents generally possessed reasonable knowledge about HIV, there were notable changes in the awareness during and after the pandemic. Social media and television were identified as primary sources of HIV information. Knowledge regarding HIV transmission and prevention increased postpandemic, particularly concerning preventive measures such as pre-exposure prophylaxis (PREP) and motherto-child transmission (MTCT). However, persistent misconceptions and stigma surrounding HIV remained, indicating the need for continued education and advocacy efforts.p>CONCLUSION<p style="text-align: justify;" data-mce-style="text-align: justify;">The study underscores the importance of utilizing social media platforms for HIV awareness campaigns, especially among youths who are disproportionately affected by the epidemic. Despite improvements in knowledge, the Philippines has yet to achieve global HIV prevention goals. Continued efforts to enhance awareness, particularly regarding recent advancements in HIV prevention and treatment, are essential for curbing the epidemic and improving public health outcomes nationwide.p>

BACKGROUND<p style="text-align: justify;" data-mce-style="text-align: justify;">Down syndrome or trisomy 21, the most common chromosomal disorder, results from the presence of a third copy of chromosome 21 and manifests as mild to moderate intellectual disability, growth retardation, congenital heart defects, gastrointestinal abnormalities, and characteristic facial features. Several methods have been used to screen for Down syndrome in the prenatal period, such as ultrasound, biomarkers, cell-free DNA testing, and combinations of these tests. A positive result from one or more of these screening tests signals the need for confirmatory karyotyping to clinch the diagnosis. Ultrasound between 11 to 14 weeks of gestation can evaluate nuchal translucency (NT) to screen for Down syndrome. During the second trimester, a triple or quadruple test can also be performed alone or in addition to NT to quantify Down syndrome risk. In limited resource settings however, only the measurement of NT via ultrasound can be performed since biomarker tests are either unavailable or inaccessible. While the diagnostic performance of NT measurement alone has been investigated in several observational studies, there is no consensus on its performance as a sole test to screen for Down syndrome.p>OBJECTIVE<p style="text-align: justify;" data-mce-style="text-align: justify;">To determine the diagnostic performance of NT during prenatal first-trimester ultrasound as a screening test for Down syndrome.p>METHODS<p style="text-align: justify;" data-mce-style="text-align: justify;">We performed a systematic search on the PubMed, ProQuest, and Cochrane Library databases for recent systematic reviews and meta-analyses that addressed the objective. The existing reviews found were then independently appraised by the two reviewers with the AMSTAR-2 checklist. To update the existing reviews, a systematic search was done in the same databases to identify additional primary diagnostic studies, which were appraised using the QUADAS-2 tool. Random-effects univariate meta-analysis and summary receiving operator curve (HSROC) analysis for the outcomes were performed using Review Manager version 5.4 and R version 4.2.2, respectively. Subgroup analysis was performed by stratifying the baseline risk of mothers for fetal anomaly as low- or high-risk. Highrisk mothers were defined as women with risk factors such as advanced age, positive serum screen, presence of other ultrasound anomalies, and history of previous fetus with anomaly.p>RESULTS<p style="text-align: justify;" data-mce-style="text-align: justify;">We found 22 cohort studies (n=225,846) of women at low-risk for fetal anomaly. The pooled sensitivity was 67.8% (95% CI: 61.4%-73.6%, I2=70.4%) and specificity was 96.3% (95% CI: 95.5%-96.9%, I2=96.7%). For low-risk women, the overall certainty of evidence was low, due to different modes of verification and heterogeneity not completely explained by variability in baseline risk or cut-points. Seven studies (n=9,197) were on high-risk women. The pooled sensitivity was 62.2% (95% CI: 54.1%-69.7%, I2=38.8%) and specificity was 96.5% (95% CI: 93.6%-98.1%, I2=95.5%). For women at high-risk, the evidence was rated as moderate due to differential verification.p>CONCLUSION<p style="text-align: justify;" data-mce-style="text-align: justify;">Our analysis showed that NT measured through first-trimester ultrasound is specific for Down syndrome but has low sensitivity. Despite this, it is a useful screening test for Down syndrome in low-resource settings where other strategies may not be available or accessible. Furthermore, interpretation of NT results must take into consideration its limited sensitivity as this may lead to missed cases.p>

BACKGROUND AND OBJECTIVES<p style="text-align: justify;" data-mce-style="text-align: justify;">COVID-19 has quickly spread over the world and became an unprecedented burden on health care systems. COVID-19 diagnosis necessitates the use of precise testing methods such as RT-PCR. This method is generally reported as positive or negative, however, studies have shown its semi-quantitative capability through Ct values. This study determined an association that exists between the Ct values, clinical features, and laboratory findings among COVID-19 patients admitted in a tertiary infectious disease hospital in Manila, Philippines. This attempts to further explore the utility of RT-PCR in disease severity classification and diagnosis.p>METHODS<p style="text-align: justify;" data-mce-style="text-align: justify;">This was an observational retrospective study that utilized a purposive sampling method, wherein patients were selected based on the DOH case definition of confirmed COVID-19, and were stratified according to disease severity. Baseline laboratory data of the patients were gathered from medical records covering the period of June 2021 to January 2022 using a Data Collection Form. Chi-square test was used to measure the degree of association between the groups and categorical variables. Regression Analysis was used to identify predictors for certain variables. SPSS Statistics for Windows, Version 25.0 was utilized for the statistical analysis.p>RESULTS<p style="text-align: justify;" data-mce-style="text-align: justify;">The total WBC, neutrophil, lymphocyte and monocyte counts, serum urea, LDH, CRP and PTT were found to be predictors of COVID-19 severity. There was no significant difference observed between the disease severity and the patient’s clinical outcome. All routine laboratory tests that were taken at baseline (ORF Gene, N-Gene, Hematocrit, White Blood Cells, Neutrophil, Lymphocyte, Monocyte, Platelet Count, Urea, Creatinine, SGPT, SGOT, Na, K, LDH, Ferritin, C Reactive Protein, Procalcitonin, D-Dimer, PT, PTT) were not significant predictors of the clinical outcome. Although WBC, neutrophil, lymphocyte, and monocyte count, urea, LDH, CRP, and PTT were predictors  of disease severity. The study also reported that the odds of having severe to critical disease increases by 20.6% for every one unit increase in neutrophil count, and 17.4% for every one unit increase in lymphocyte count. Among the laboratory parameters, neutrophil count (p=0.010654063) and urea (p= 0.04149874 have direct relationship with the N gene Ct values while Orf gene Ct Values have direct relationship with lymphocyte count (p=0.01269027). Similarly, regression showed that as monocyte count, creatinine levels, and serum ferritin decrease, Ct values increase. Sex was found to not be a significant predictor of disease severity and clinical outcome. There was also no significant difference observed between the disease severity and the patient’s clinical outcome.p>CONCLUSION<p style="text-align: justify;" data-mce-style="text-align: justify;">The study showed that the Ct values for both ORF and N genes were not significant predictors of both disease severity and clinical outcome. However, ORF gene Ct values have direct relationship with lymphocyte counts while N gene Ct values have direct correlation with neutrophil count and urea levels. Similarly, monocyte, creatinine, and ferritin are negatively correlated with Ct values. It is important to monitor the patient’s laboratory biomarkers in order to determine the proper course of treatment and management for each case.p>

BACKGROUND AND OBJECTIVE<p style="text-align: justify;" data-mce-style="text-align: justify;">COVID-19 has been associated with cardiac injury, often detectable through electrocardiographic (ECG) changes. This study seeks to characterize the cardiovascular and electrocardiographic profiles of adult patients diagnosed with COVID-19.p>METHODS<p style="text-align: justify;" data-mce-style="text-align: justify;">This study included adult patients with confirmed COVID-19 from June 2021 to June 2022. Clinical profiles and 12-lead ECG tracings were obtained from electronic medical records and reviewed independently by three cardiologists. Descriptive analysis was performed to summarize the cardiovascular and electrocardiographic findings in this population.p>RESULTS<p style="text-align: justify;" data-mce-style="text-align: justify;">The study included 998 COVID-19 patients (mean age: 50 years; 53.7% male). The most common comorbidities were hypertension, diabetes, and dyslipidemia. A majority (31.36%) presented with severe COVID-19 infection. The most frequent significant ECG abnormalities observed at admission were sinus tachycardia (22.8%), and atrial fibrillation (11.02%). Additional ischemic findings included ST segment depression (2.91%), T-wave inversion (1.70%), and ST segment elevation (2.71%).p>CONCLUSION<p style="text-align: justify;" data-mce-style="text-align: justify;">The baseline ECG findings among COVID-19 patients were predominantly normal; however, significant abnormalities were also identified. The most frequent abnormalities included sinus tachycardia, atrial fibrillation, and ischemic changes, all of which may have clinical implications.p>
