Scabies in the Philippines: A Secondary Analysis of Local Patient Registries.

Background: Scabies is the second most common cause of disability among skin diseases in the Philippines as of 2019. There is no large nationwide study describing the epidemiologic profile of scabies in the country. Objective: This study aimed to describe the demographic, seasonal, and geographic profile of scabies in the Philippines. Methods: We compared secondary data of two local patient registries (Philippine Dermatological Society, PDS, 2010 to 2021; and Philippine Pediatric Society, PPS, 2009 to 2021) for reported cases of scabies in the Philippines. We reported the frequency and percentage distribution according to age, sex, month, year, and type of diagnosis, and region. Results: The median annual frequency of scabies cases (mostly outpatient) for PDS (from year 2010) was 4087 (range ([QR], 342-6422 [3271.5]), while it was 183 (range [IQR], 64-234 [96.5]) (all inpatient) for PPS (from year 2009). There was a reduction to one-third (PDS) and one-fourth (PPS) of pre-pandemic numbers during the pandemic years (2020-2021). The peak months for scabies cases were the cooler months: January (median, 12.1% of annual cases; range [IQR], 2.6%-31.4% [3.6%]) to February (median, 10.0% of annual cases; range [IQR], 1.5%-27.8% [2.5%]) based on PDS data, and November (median, 10.0% of annual cases; range [IQR], 0.0%-24.3% [7.0%]) to January (median, 9.0% of annual cases; range [IQR], 0.0%-24.3% [6.6%]) for PPS data. Overall, for PDS, age 1-4 years is the most affected age group (median, PDS, 17.5% of annual cases; range [IQR], 11.9%-25.4% [8.1%]), while it was the less than 1-year-olds (median annual cases, 48.9%; range [IQR], 29.1%-67.3% [13.20%]) among PPS pediatric population aged 0 to 18 years. Males (median, 53.9% of annual cases; range [IQR], 45.0%-67.2% [8.8%]) were more affected than females in PPS. While for PDS during earlier years (prior to 2015), males (median, 51.6% of annual cases from 2010 to 2014; range [IQR], 47.4%-52.9% [0.2%]) were more affected than females. However, males became less affected than females with median, 44.7% of annual cases from 2015 onwards (range [IQR], 43.4%-46.5% [1.2%]). NCR was the region with the highest frequency of cases in PPS (median, 52.6% of annual cases; range [IQR], 22.7%-75.0% [20.4%]). The 2nd most affected regions were Central/Eastern Visayas (34.2%, 2009-2013; range [IQR], 17.9%-54.1% [5.3%]), Bicol region (12%; 2014 to 2018; range [IQR], 17.9%-54.1% [7.4%]), Central Luzon (18%; 2019), Central/Eastern Visayas (29%, 2020), and Northern/Central Mindanao (17%, 2021). Conclusion: Scabies was commonly seen in the younger age group, slightly more in females in the PDS, while slightly more among males in the PPS, in the cooler months of the year, and in the urbanized NCR.

The Distribution of Dermatologists in the Philippines.

BACKGROUND: Equitable health manpower distribution is essential for the successful implementation of the Universal Health Care (UHC) program by the Philippine Department of Health. Mapping the distribution and profile of dermatologists in the Philippines can improve Filipinos' access to skin disease treatment. METHODS: A review of the database of dermatologists from the Philippine Dermatological Society (PDS) members' directory (as of November 2023), as well as the Philippine Health Insurance Corporation (PhilHealth) database (as of July 2023), was conducted. The distribution of PDS-accredited dermatologists was analyzed by geographic location, demographic profile (age and sex), density (per 100,000 people), and the dermatologist-to-general practitioner (GP) ratio. Heatmaps illustrating the distribution of dermatologists in the Philippines and the ratio of PhilHealth-accredited PDS board-certified dermatologists to GPs were created. RESULTS: Out of 1389 PDS board-certified dermatologists, 1345 resided in the Philippines. The majority were women (1221/1345, 90.78%), with a median age of 47 years (range: 23 to 85). More than half were practicing in the National Capital Region (NCR) (684/1345, 50.86%). The overall dermatologist density was approximately 1 per 100,000 people (1.19); it was highest for the Luzon Island group (1.54) (NCR, 4.80) and lowest for the Mindanao Island group (0.27; the Bangsamoro Autonomous Region of Muslim Mindanao or BARMM, 0.04). Less than one-third (396/1345, 29.44%) of dermatologists were PhilHealth-accredited, with a density of 0.35 dermatologists per 100,000 people. Out of 45218 PhilHealth-accredited physicians, 396 (0.88%) were dermatologists while 11748 (25.98%) were GPs. The overall dermatologist-to-GP ratio among PhilHealth-accredited physicians was 1:30; it was highest in the Luzon Island group (1:20) and lowest in the Mindanao Island group (1:118). CONCLUSION: The Philippines lacks dermatologists in regions outside the NCR. The majority are women, and few are PhilHealth-accredited. The dermatologist-to-GP ratio among PhilHealth-accredited physicians is low. Dermatology training programs should encourage more applicants, especially men, and prioritize applicants from underserved regions.

Outcomes of patients with COVID-19 and coronary artery disease and heart failure: findings from the Philippine CORONA study.

BACKGROUND: Patients with coronavirus disease 2019 (COVID-19) and coronary artery disease (CAD) or heart failure (HF) are more likely to have poor outcomes. This study aimed to determine the characteristics and outcomes of COVID-19 patients with CAD/HF across various institutions in the Philippines. METHODS: We utilized the data from the Philippine CORONA Study and compared the outcomes of admitted COVID-19 patients with CAD/HF versus those without. The Student's t test, Mann-Whitney U test, binary logistic regression and multivariate regression analysis were utilized. Odds ratios (OR) and Kaplan-Meier curves were generated. RESULTS: We included a total of 512 patients with COVID-19 had CAD/HF and 10,369 were without. CAD/HF was significantly associated with COVID severity, all-cause mortality, death from cardiac causes, respiratory failure, and prolonged hospitalization. After adjusting for confounders, the presence of CAD/HF was still associated with death from a cardiac cause (OR 2.22, 95% CI 1.49-3.3, p < 0.01). CONCLUSIONS: The presence of CAD or HF was significantly associated with severity of COVID disease, all-cause mortality, death from cardiac causes, respiratory failure, and prolonged hospitalization.

Association between the Preoperative Standard Uptake Value (SUV) and Survival Outcomes after Robotic-Assisted Segmentectomy for Resectable Non-Small Cell Lung Cancer (NSCLC).

BACKGROUND: Lung-sparing procedures, specifically segmentectomies and wedge resections, have increased over the years to treat early-stage non-small cell lung cancer (NSCLC). We investigate here the perioperative and long-term outcomes of patients who underwent robotic-assisted segmentectomy (RAS) at an NCI-designated cancer center and aim to show associations between the preoperative standard update value (SUV) to tumor stage, recurrence patterns, and overall survival. METHODS: A retrospective analysis was performed on 166 consecutive patients who underwent RAS at a single institution from 2010 to 2021. Of this number, 121 robotic-assisted segmentectomies were performed for primary NSCLC, and a total of 101 patients were evaluated with a PET-CT scan. The SUV from the primary tumor was determined from the PET-CT. The clinical, surgical, and pathologic profiles and perioperative outcomes were summarized via descriptive statistics. Numerical variables were described as the median and interquartile range because all numerical variables were not normally distributed as assessed by the Shapiro-Wilk test of normality. Categorical variables were described as the count and proportion. Chi-square or Fisher's exact test was used for association. The main outcomes were overall survival (OS) and recurrence-free survival (RFS). Kaplan-Meier (KM) curves were constructed to visualize the OS and RFS, which were also stratified according to tumor histology, the pathologic stage, and standard uptake value. A log-rank test for the equality of survival curves was performed to determine significant differences between groups. RESULTS: The most common postoperative complications were atrial fibrillation (8.8%, 9/102), persistent air leak (7.84%, 8/102), and pneumonia (4.9%, 5/102). The median operative duration was 168.5 min (IQR 59), while the median estimated blood loss was 50 mL (IQR 125). The conversion rate to thoracotomy in this cohort was 3.9% (4/102). Intraoperative complications occurred in 2.9% (3/102). The median hospital length of stay was 3 days (IQR 3). The median chest tube duration was 3 days (IQR 2), but 4.9% (5/102) of patients were sent home with a chest tube. The recurrence for this cohort was 28.4% (29/102). The time to recurrence was 353 days (IQR 504), while the time to mortality was 505 days (IQR 761). The NSCLC patients were divided into the following two groups: low SUV (<5, n = 55) and high SUV (≥5, n = 47). Statistically significant associations were noted between SUV and the tumor histology (p = 0.019), tumor grade (p = 0.002), lymph-vascular invasion (p = 0.029), viscera-pleural invasion (p = 0.008), recurrence (p < 0.001) and the site of recurrence (p = 0.047). KM survival analysis showed significant differences in the curves for OS (log-rank p-value 0.0204) and RFS (log-rank p-value 0.0034) between the SUV groups. CONCLUSION: Robotic-assisted segmentectomy for NSCLC has reasonable perioperative and oncologic outcomes. Furthermore, we demonstrate here the prognostic implication of preoperative SUV to pathologic outcomes, recurrence-free survival, and overall survival.

Clinical Outcomes of COVID-19 Infection among Patients with Chronic Obstructive Pulmonary Disease: Findings from the Philippine CORONA Study.

BACKGROUND: The global pandemic caused by the coronavirus disease 2019 (COVID-19) resulted in many deaths from fulminant respiratory failure. Chronic obstructive pulmonary disease (COPD) is the leading cause of morbidity and mortality worldwide. There has been great concern regarding the impact of COPD on the COVID-19 illness. METHODS: Data from the Philippine CORONA study were analyzed to determine the association of COPD and COVID-19 in terms of mortality, disease severity, respiratory failure, mechanical ventilation, and lengths of stay in the intensive care unit (ICU) and hospital. RESULTS: A total of 10,881 patients were included in this study, and 156 (1.4%) patients had been diagnosed with COPD. A majority of COVID-19 patients with COPD had other existing comorbidities: hypertension, diabetes mellitus, chronic cardiac disease, and chronic kidney disease. COPD patients were 2.0× more likely to present with severe to critical COVID-19 disease. COVID-19 patients with COPD in our study have a 1.7× increased mortality, 1.6× increased respiratory failure, and 2.0× increased risk for ICU admission. Smokers with COVID-19 were 1.8× more likely to present with more severe disease and have a 1.9× increased mortality. CONCLUSION: Our study supports the growing evidence that COPD among COVID-19 patients is a risk factor for higher mortality, more severe form of COVID-19, higher ICU admission, and higher respiratory failure needing ventilatory support.

Outcomes and Risk Factors of Patients With COVID-19 and Cancer (ONCORONA): Findings from The Philippine CORONA Study.

Background: A study conducted in China on patients with coronavirus disease 2019 (COVID-19) showed that cancer conferred a five times increased risk for needing intensive care admission and mortality; No data has yet been collected and published from the Philippines. Thus, the investigators conducted this substudy to determine the association of having a history of cancer with clinical outcomes among patients included in the Philippine CORONA Study. Methodology: Multi-center, retrospective cohort design. Results: A total of 244 patients had a history of cancer, out of 10,881 COVID-19 hospital admissions. After adjusting for different confounding variables of interest, having cancer was significantly associated with a 75% increased odds of having severe/critical COVID-19 at nadir (CI 95% 1.32, 2.33; p < 0.001). After adjusting for different confounding variables of interest, having cancer was significantly associated with the following time-to-event outcomes: 72% increase in hazard of in-hospital mortality (CI 95% 1.37, 2.16; p < 0.001), 65% increase in hazard of respiratory failure (CI 95% 1.31, 2.08; p < 0.001), and 57% increase in hazard of being admitted to ICU (CI 95% 1.24, 1.97; p < 0.001). Conclusion: A history of cancer conferred poorer clinical outcomes on adult, hospitalized COVID-19 patients.

Preferences for Communication About End-of-Life Care in Atypical Parkinsonism.

BACKGROUND: Studies on preferences regarding discussions on end-of-life care (EOLC), advance care planning (ACP), medical assistance in dying (MAiD), and brain donation have not yet been conducted in patients with atypical parkinsonism (AP). OBJECTIVE: The aim of this study was to know the preferences of patients with AP regarding discussions on EOLC, ACP, MAiD, and brain donation. METHODS: This cross-sectional study was conducted in patients clinically diagnosed with AP. An adapted questionnaire that assessed various potential factors that affect patients' preferences regarding EOLC and ACP was sent through postal mail to 278 patients. RESULTS: A total of 90 completed questionnaires were returned. Most patients preferred to discuss at the time of diagnosis information about the disease, its natural course, treatment options, and prognosis. In contrast, they preferred that EOLC and ACP be discussed when the disease has progressed. No demographic or disease-related factors were found to be predictors of the patient's preferences. Notably, most patients (63.3%) had previous actual discussions on these issues. Less than a third of patients were open to discussions about MAiD and brain donation; older age and the importance of spirituality and religion decreased the odds of discussing these. CONCLUSIONS: Our study demonstrates that patients with AP have preferences regarding the timing of the discussion of the different themes surrounding EOLC and ACP. A needs-based approach in initiating and conducting timely discussions on these difficult but essential issues is proposed. A thorough explanation and recognition of a patient's beliefs are recommended when initiating conversations about MAiD and brain donation. © 2021 International Parkinson and Movement Disorder Society.

HLA-A, -B, and -DRB1 genotyping and haplotype frequencies among Filipinos living in the National Capital Region of the Philippines.

In this report, HLA polymorphisms (A, B, and DRB1 loci) were determined in 51 unrelated Filipinos. Molecular genotyping was carried out by sequence-based typing (Sanger sequencing). Data were analyzed by HLA-net GENE[RATE] tools. HLA-A, -B and -DRB1 genotype frequencies were at Hardy-Weinberg equilibrium. A*11, B*15, and DRB1*15 were the most frequent allele groups, while A*11-B*15-DRB1*15 was the most frequent HLA-A-B-DRB1 haplotype. HLA data are available in the Allele Frequencies Net Database (AFND: 3690) under the population name "Philippines National Capital Region".
