BACKGROUND AND OBJECTIVE

Endocrine Disrupting Chemicals (EDCs) are ubiquitously found as low-level contaminants and pose serious threat to women’s health. EDCs may result in various reproductive disorders, fetal birth and developmental abnormalities, and endocrine and metabolic disorders. EDCs can be detected in body fluids of exposed individuals including blood and urine. This study aimed to detect four EDCs — Methyl Paraben (MP), 2,4-Dichlorophenoxyacetic acid (2,4-D), Monobutyl Phthalate (MBP), and Bisphenol A (BPA) in urine samples of women using Ultra-Performance Liquid Chromatography – Quadrupole Time-of-Flight (UPLC-QTOF) mass spectrometry.

Sequential steps of enzymatic deconjugation, liquid-liquid extraction, solid phase extraction, and liquid chromatography separation and mass spectrometry detection were optimized in urine samples. The method was used to analyze 70 urine samples from women of reproductive age.

The sample preparation method showed a recovery ranging from 86.6% (MBP) to 100 % (2,4-D). The method demonstrated limits of quantitation ranging from 1.52 ng/m(MP) to 6.46 ng/mL(2,4D). Intra-day precisions expressed as relative standard deviation were all below 15% while accuracy was shown to range from 67.10% (2,4-D) to 102.39% (MBP). MP was detected in nine samples (12.86%) with a geometric mean value of 10.15 ng/ml (range: 3.62-52.39 ng/ml). MBP was detected in 68 samples (97.14%) with a geometric mean value of 97.62 ng/ml (range: 15.32-698.18 ng/ml). BPA was detected only once (9.58 ng/ml) while 2, 4-D was not detected in all samples.

A UPLC-QTOF mass spectrometry method to detect four EDCs at parts per billion level (ng/ml) was adapted and applied for analysis of urine samples. This method can find applicability in routine testing of clinical specimens as well as surveillance and other epidemiological studies.

INTRODUCTION

Patients with diabetes are at higher risk of developing severe COVID-19 infection with a two-fold increased risk of mortality. This study described the risk factors affecting clinical outcomes of confirmed COVID-19 patients with diabetes mellitus at the University of Santo Tomas Hospital, Manila, Philippines.

This retrospective study included 204 patients with COVID-19 (34 with known type 2 diabetes and 2 with new-onset diabetes) from March to October 2020. Clinical characteristics and laboratory parameters were collected and analyzed in subjects with diabetes. A univariate logistic regression was used to calculate the odds ratios and 95% confidence interval (CI) for the patient’s risk factors associated with mortality or poor prognosis.

Moderate COVID-19 infection occurred in 52.8% of type 2 diabetes mellitus (T2DM) patients and critical COVID-19 infection in 27.8%. All patients with critical COVID-19 infection presented with acute respiratory distress syndrome, half had concomitant septic shock and respiratory failure was observed in 27.8%. The average length of hospital stay was approximately 17.5 days. T2DM patients with established atherosclerotic cardiovascular disease (ASCVD) are 5.1 times (95% CI 1.2 to 21.4) more likely to develop severe or critical COVID-19 infection, and more likely to stay in the hospital for more than 14 days. HbA1c >8.5% is a potential risk (OR = 3.7, 0.6 to 21.6) for severe to critical disease. T2DM patients with concomitant coronary artery disease are 7.6 times (95% CI 1.3 to 43.4) more likely to stay longer (more than 14 days) as compared to those without existing coronary artery disease. Prior statin use was a significant risk factor for ICU admission (p-value 0.0341). Other potential risk factors affecting clinical outcomes are obesity (OR 3, 0.4 to 22.7), prior use of thiazolidinedione (OR 7.8, 0.5 to 126.7) or sodium-glucose transporter 2 (SGLT2) inhibitors (OR 7.5, 0.4 to 145) and prior use of anti-thrombotic (OR 4.6, 0.4 to 56.8). The recovery rate of T2DM patients hospitalized for COVID-19 infection was 86.1%.

Patients with T2DM are more vulnerable to COVID-19 infection. The presence of established ASCVD increases the likelihood of severe COVID-19 disease as well as longer length of hospital stay for more than 14 days. Early recognition and prompt treatment led to a favorable recovery rate.

OBJECTIVE

This study aimed to determine if selenium supplementation for a period of six months can decrease signs and prevent worsening of mild Graves’ ophthalmopathy among Filipino patients.

We conducted an open-label, assessor-masked, randomized controlled trial involving adult patients diagnosed with mild Graves’ ophthalmopathy. Participants were divided into two groups: one group received standard care (eye drops) alone (control group), while the other group received an additional 200 mcg/day oral selenium supplementation alongside standard care. Inclusion criteria encompassed adult patients with Graves’ hyperthyroidism presenting at least one sign of mild ophthalmopathy and a disease duration of less than 18 months. Statistical analyses were performed using independent sample t-test, Mann-Whitney U test and Fisher’s Exact/Chi-square test to compare means, ranks and frequencies between the two intervention groups. Paired sample t-test, Wilcoxon signed rank test and McNemar test were employed to assess changes from baseline to the third and sixth month observations.

A significant difference in clinical activity score (CAS) was observed between the selenium supplementation group and the control group. Initially, 14 eyes (33.33%) in the selenium group exhibited a CAS score of 0, which increased to 27 eyes (64.29%) at the third month of treatment and slightly decreased to 26 eyes (61.9%) at the sixth month. Conversely, the control group had 11 eyes with a CAS score of 0 at baseline, which increased to 16 eyes (38.1%) at three months and decreased to 14 eyes (33.33%) at the sixth month. The improvement in CAS was significantly associated with reductions in caruncle and plica swelling (p = 0.040). Further analysis revealed a statistically significant difference in CAS between the treatment and control groups (p = 0.017) at the sixth month mark.

Selenium supplementation provided significant benefit in reducing the signs and preventing deterioration of mild Graves’ ophthalmopathy, as indicated by improved CAS scores. Future research exploring baseline and end of treatment selenium concentrations in the Philippines is recommended to further substantiate these findings.

Conclusion A UPLC-QTOF mass spectrometry method to detect four EDCs at parts per billion level (ng/ml) was adapted and applied for analysis of urine samples. This method can find applicability in routine testing of clinical specimens as well as surveillance and other epidemiological studies.

OBJECTIVES

To validate a method in detecting SARS-CoV-2 via RT-qPCR in pregnant and non-pregnant samples other than nasopharyngeal swabs and/or oropharyngeal swabs such as cervical, rectal, amniotic fluid, placental, umbilical cord blood, and breastmilk.

We performed a validation experiment using MGI easy extraction kits and BGI PCR kits on non-conventional specimens, including cervical, rectal, amniotic fluid, placental, umbilical cord blood, and breastmilk to detect and confirm the presence of SARS-CoV-2. In addition, we tested the validated method on 572 purposively sampled field-collected non-conventional specimens from a cohort of 109 unvaccinated pregnant and 47 unvaccinated non-pregnant women to assess which candidate non-conventional maternal- and fetal-associated specimens may contribute to maternal-fetal viral vertical transmission.

Positive detection of SARS-CoV-2 viral RNA in non-conventional specimens was demonstrated and verified. Of the 572 non-conventional samples tested, 1.8% (10/572) were positively validated by RT-qPCR for SARS-CoV-2 in the maternal-associated specimens particularly the rectal (5), placental (1), and cervical (4) swabs among six pregnant and four non-pregnant individuals. In contrast, no SARS-CoV-2 viral RNA was detected in fetal-associated specimens.

The results of the validation study may serve as an additional diagnostic screening layer to support maternal-child care. Furthermore, viral detection in these non-conventional maternal specimens may also be utilized to provide guidance in the clinical management of neonates, and pregnant women during delivery.

BACKGROUND: Polycystic ovarian syndrome (PCOS) is a prevalent condition affecting women of reproductive age, characterized by metabolic, endocrine, and reproductive disturbances including insulin resistance, abnormal uterine bleeding, infertility, and hyperandrogenism, and is associated with diabetes and cardiovascular disease. The etiology of PCOS is unclear and exposure to endocrine-disrupting chemicals (EDCs) present in everyday products may play a role by disrupting hormonal pathways. OBJECTIVES: To determine the association between exposure to EDC-containing products, sociodemographic factors, and PCOS diagnosis among nonpregnant reproductive-aged women. MATERIALS AND METHODS: A survey assessed the frequency of EDC exposure in homes and workplaces. The Rotterdam Criteria were used for the diagnosis of PCO features with clinical history and ultrasound. The association between PCOS and EDC exposure was determined using Chi-square and logistic regression analysis. RESULTS: The study identified significant sociodemographic factors associated with PCOS (P < 0.001) including age, civil status, and household income. Increased likelihood of PCOS was linked to frequent use of scented candles (odds ratio [OR] = 2.07), cleaning sprays (OR = 2.28), and floor polish (OR = 2.07), exposure to new upholstered furniture (OR = 4.00), thermal receipts (OR = 2.16), and consumption of microwaved and processed foods (OR = 2.60), as well as water sourced from wells (OR = 7.69). Additional associations were found with access to public markets (OR = 0.26) and the use of paper food wrappers (OR = 1.72). CONCLUSION These findings suggest that frequent exposure to EDC-containing products and certain sociodemographic factors may contribute to the development of PCOS among women of reproductive age. Results underscore the importance of reducing exposure to EDCs to prevent or mitigate the development of PCOS and other reproductive consequences.

Context: Exposure to environmental pollutants (EP) and Endocrine-disrupting chemicals (EDCs) is associated with several general negative health effects which compromise women's reproductive health, maternal, and neonatal outcomes. Unfortunately, many nonpregnant and pregnant women are unaware of their active exposure to these potentially slow-acting toxic substances, EPs, and EDCs. At any stage of life, and in the long-term minute exposures, there is no established safe level of exposure to these substances. Due to the potentially harmful effects on women in general, and to the pregnant and her unborn child in particular, it is important to establish the prevalence of their exposure. Aims: The aim of this study was to determine the magnitude (prevalence) of exposure among nonpregnant and pregnant women aged 18–49 years to common EPs/EDCs such as bisphenol A, pesticides, phthalates, and perfluorinated compounds among others. Settings and Design : This study was conducted at the Philippine General Hospital, University of the Philippines Manila. Subjects and Methods : The study participants were nonpregnant and pregnant women, with low-risk singleton pregnancy, and had a prenatal checkup and eventual delivery at the Philippine General Hospital. After consent, women were asked to answer a survey focused on their sociodemographics and frequency of exposure to EP- and EDC-containing items. Satatistical Analysis Used: Descriptive statistics were used to summarize the demographic and clinical characteristics of the patients. Null hypotheses were rejected at 0.05 α-level of significance. The computer software STATA 13.1 was used for data analysis. Results: One hundred and fifty-nine survey responses by women were analyzed. Possible EDC-containing household items (carpets, linoleum, upholstered, and stain-resistant furniture) are more prevalent in the homes of pregnant women compared to nonpregnant women. Pregnant women are also exposed to wallpapers compared to nonpregnant individuals. Nonpregnant women were 1.5 times more exposed to lotions. Unexposure to hand sanitizers is 1.3 times higher among pregnant individuals. Conclusions There are differences in the prevalence of exposure to household EDC-containing items between pregnant and nonpregnant women, with pregnant women having a higher prevalence of exposure.

The presence of autoantibodies is a common link between autoimmune hypothyroidism (AH) and Systemic Lupus Erythematosus (SLE). The coexistence of AH (Hashimoto’s Thyroiditis) and SLE is common; however, massive pericardial effusion (PEEF) with signs of tamponade is extremely rare and only a few cases have been reported in literature. We present a case of a 54-year-old female who came in with progressive dyspnea who was found out to have massive PEEF from overt AH and concurrent SLE, which was successfully managed medically. This gave us valuable insight that massive pericardial effusion occurring in overt hypothyroidism may be secondarily caused by other co-existing disease entities such as SLE. The importance of the correct diagnosis cannot be overemphasized, as this largely contributed to the successful management of this case.

Background: Gastrointestinal stromal tumors (GIST) is defined as specific, typically kit (CD117)-positive and CKIT or platelet-derived growth factor receptor alpha (PDGFRA) mutation-driven mesenchymal tumors that can occur anywhere in the GI tract. GIST diagnosis relies heavily on immunohistomorphology. However, with the advent of molecular testing, the classification, diagnosis and targeted-therapy for gastrointestinal mesenchymal tumors have been greatly improved. In the Philippines, molecular testing is not yet readily available as in other countries. The local molecular profile of gastrointestinal stromal tumors is a point of investigation as treatment may be more tailored to the patients’ needs. Objective: This study aims to determine the prevalence of CKIT and PDGFRA mutations among formalin-fixed and paraffin embedded gastrointestinal stromal tumors and other gastrointestinal mesenchymal tumors in St. Luke’s Medical Center – Quezon City. Methods: A retrospective cross-sectional study of formalin fixed and paraffin embedded tumor samples diagnosed as Gastrointestinal Stromal Tumor from January 1, 2009 to December 31, 2017 will be analyzed for KIT and PDGFRA mutations. Result: The epidemiology of GIST remains constant in that mean age group is the 5th to 6th decade, with equal gender distribution, and stomach followed by small bowel are the most common sites. Mutational analysis of the GISTs showed predominantly KIT Exon 11 (47.83%) followed by CKIT Exon 9 (13.04%) and PDGFRA Exon 18 (10.87%). For KIT Exon 11, deletion is the most common mutations followed by point mutations. No mutation is detected in 47.83% of GISTs. Conclusion Mutational analysis for CKIT-PDGFRA is warranted among GIST patients, as it may significantly influence treatment protocol in our patients.
