INTRODUCTION: XELOX is non-inferior to FOLFOX-4 as a first-line treatment for metastatic colorectal cancer. This study compares the costs associated with XEL0X+/-bevacizumab versus FOLFOX4+/-bevacizumab in a non-reimbursed, out of pocket Philippine health care system.
METHODS: This is a cost-minimization analysis using Philippine General Hospital as base case and a typical Filipino patient of 60 kg with BSA 1.66. The outcome data were derived from the N016966 trial. These included the drugs capecitabine, 5-fluorouracil, oxaliplatin, and bevacizumab (BEV); chemotherapy cycles and corresponding hospital admission for each regimen; resources associated with treatment of adverse events such hospital days, ambulatory consultations, concomitant
medication, and central venous line insertion/removal, with costs and charges based on the local setting.
RESULTS: Highest cost (direct and/or indirect) was for FOLFOX4+BEV, followed by XEL0X+BEV, FOLFOX4, and then XELOX. The use of XELOX resulted in a cost saving of PhP 158,642 per patient compared with FOLFOX4. The use of XEL0X+BEV resulted in a cost saving of PhP 186,144 per patient compared with FOLFOX4+BEV.
CONCLUSION: XEL0X+/-BEV is less costly than FOLFOX4-F/-BEV in an out-of-pocket Philippine tertiary hospital setting from the patient's perspective.

INTRODUCTION: A multidisciplinary approach is essential to optimize patient care. In the practice of oncology, surgeons, medical oncologists, and pathologists are essential for the histology-based diagnosis of cancer patients. In breast cancer, hormone receptor and HER2 positivity are both predictive and prognostic, and so testing for these has been strongly recommended for every newly diagnosed breast cancer patient. A unique but meaningful information that can be provided by medical oncologists, as customers, is their satisfaction to the services (e.g. HER2 testing) and product (e.g. reports) of the pathology laboratory. Any quality initiative effort to improve HER2 testing can also be extended to hormone receptor (ER/PR) testing. This study measures the general satisfaction of medical oncologists practicing in Metro Manila with local HER2 testing services and reports.
METHODS: This cross-sectional study had survey questionnaires distributed to medical oncologists practicing in Metro Manila chosen on the basis of their considerable experience with requesting HER2tests and with the use of anti-HER2 therapy in their management of breast carcinoma patients. Demographics, practice information, rating of satisfaction per laboratory service category, and a checklist of elements of IHC/FISH reports were collected.
RESULTS: 32 medical oncologists participated in the survey, most of whom were from tertiary hospitals. Breast carcinoma cases make up around 26-50% of cancer cases in their practice. More than half request HER2 testing for their breast cancer patients. Medical oncologists are generally satisfied with the services for IHC and FISH HER2 testing (composite scores >2) provided by the laboratories. Overall, medical oncologists were very satisfied with diagnostic accuracy and completeness of relevant information in the report. Laboratory services were mostly rated good, with the exception of pathologists' responsiveness to problems and notification of equivocal results. For both IHC and FISH, patient/physician identification, date of service, specimen identification/ site/ type, results, and interpretation were reported to be included in the reports. However, time to/duration of/ type of fixation, method and image analysis method, antibody clone/ vendor, and comment that an FDA-approved method was used, were reported missing by the many.
CONCLUSION: For both IHC and FISH, overall satisfaction was found to be moderately directly correlated with diagnostic accuracy. In a country like the Philippines where quality initiatives of laboratories may still be far from ideal, medical oncologists can demand inclusion of their preferences into assessments processes by laboratories and correct assumptions of laboratory managers as to what element of the services and products they value most. Measurement of customer satisfaction can be integrated into the quality assurance programs of laboratories and corresponding hospitals.

INTRODUCTION:
Infant gastroesophageal reflux disease (GERD) is a significant cause of concern to parents. This study seeks to describe GERD prevalence in infants, evaluate possible risk factors and assess common beliefs influencing management of GERD among Asian parents.
METHODS:
Mother-infant dyads in the Singapore PREconception Study of long-Term maternal and child Outcomes (S-PRESTO) cohort were prospectively followed from preconception to 12 months post-delivery. GERD diagnosis was ascertained through the revised Infant Gastroesophageal Reflux Questionnaire (I-GERQ-R) administered at 4 time points during infancy. Data on parental perceptions and lifestyle modifications were also collected.
RESULTS:
The prevalence of infant GERD peaked at 26.5% at age 6 weeks, decreasing to 1.1% by 12 months. Infants exclusively breastfed at 3 weeks of life had reduced odds of GERD by 1 year (adjusted odds ratio 0.43, 95% confidence interval 0.19-0.97, P=0.04). Elimination of "cold or heaty food" and "gas producing" vegetables, massaging the infant's abdomen and application of medicated oil to the infant's abdomen were quoted as major lifestyle modifications in response to GERD symptoms.
CONCLUSION
Prevalence of GERD in infants is highest in the first 3 months of life, and the majority outgrow it by 1 year of age. Infants exclusively breastfed at 3 weeks had reduced odds of GERD. Cultural-based changes such as elimination of "heaty or cold" food influence parental perceptions in GERD, which are unique to the Asian population. Understanding the cultural basis for parental perceptions and health-seeking behaviours is crucial in tailoring patient education appropriately for optimal management of infant GERD.

INTRODUCTION:
Pregnant women are reported to be at increased risk of severe coronavirus disease 2019 (COVID-19) due to underlying immunosuppression during pregnancy. However, the clinical course of COVID-19 in pregnancy and risk of vertical and horizontal transmission remain relatively unknown. We aim to describe and evaluate outcomes in pregnant women with COVID-19 in Singapore.
METHODS:
Prospective observational study of 16 pregnant patients admitted for COVID-19 to 4 tertiary hospitals in Singapore. Outcomes included severe disease, pregnancy loss, and vertical and horizontal transmission.
RESULTS:
Of the 16 patients, 37.5%, 43.8% and 18.7% were infected in the first, second and third trimesters, respectively. Two gravidas aged ≥35 years (12.5%) developed severe pneumonia; one patient (body mass index 32.9kg/m2) required transfer to intensive care. The median duration of acute infection was 19 days; one patient remained reverse transcription polymerase chain reaction (RT-PCR) positive >11 weeks from diagnosis. There were no maternal mortalities. Five pregnancies produced term live-births while 2 spontaneous miscarriages occurred at 11 and 23 weeks. RT-PCR of breast milk and maternal and neonatal samples taken at birth were negative; placenta and cord histology showed non-specific inflammation; and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific immunoglobulins were elevated in paired maternal and umbilical cord blood (n=5).
CONCLUSION
The majority of COVID-19 infected pregnant women had mild disease and only 2 women with risk factors (obesity, older age) had severe infection; this represents a slightly higher incidence than observed in age-matched non-pregnant women. Among the women who delivered, there was no definitive evidence of mother-to-child transmission via breast milk or placenta.
