OBJECTIVE
To determine the prevalence of rectal colonization with carbapenem-resistant organisms (CRO) among PGH neonatal intensive care unit (NICU) patients.
METHODOLOGYA prospective single-center observational study conducted over a 1-month period included all NICU 3 and cohort area patients admitted on April 24, 2024. Rectal swabs were collected for multidrug-resistant organism (MDRO) screening and repeated weekly for 1 month while admitted. Swabs were inoculated on chromogenic media, and isolates were identified and tested for antimicrobial sensitivity by disk diffusion. Clinical characteristics and outcomes were collected for 30 days from initial MDRO screening. Descriptive statistics were used to summarize the data.
RESULTSThe point prevalence of CRO colonization was 37% (14 of 38) at initial screening. There were 14 incident colonizations, hence the 4-week period prevalence of CRO colonization was 72.5% (29 of 40). The patients were mostly very preterm, very low birth weight neonates, majority were tested within the first 2 weeks of life, and half were exposed to meropenem at initial screening. Nosocomial infection developed in 29% and 64%, and 30-day mortality rate was 8% and 21% among initially non-CRO-colonized and CRO-colonized patients respectively. Despite high CRO colonization, no culture-proven CRO infection was observed. Surveillance screening documented persistent CRO colonization in 37%, but no decolonization. Escherichia coli, Klebsiella spp. and Serratia spp. were the most common colonizers.
CONCLUSIONThe high prevalence of rectal CRO colonization in the NICU emphasizes the burden of antimicrobial resistance, but despite the high CRO colonization, no CRO infection was documented from the limited sample and study period.

BACKGROUND
The use of ceftazidime-avibactam (CAZ-AVI) has been recently introduced to combat multidrug-resistant organisms (MDROs) in the pediatric population. Case reports have documented the successful off-label use of CAZ-AVI in the treatment of MDRO sepsis in neonates; however, data remains to be limited, especially in the Philippines.
OBJECTIVESThis study aims to explore the effects of CAZ-AVI on clinical outcomes including mortality rate, length of hospital stay since treatment initiation, and bacteriological eradication among patients admitted at the NICU with MDR Klebsiella hospital-acquired sepsis. Other objectives include comparing these outcomes betwee those who received CAZ-AVI (in combination with aztreonam, ATM) and those who received other 2nd line MDR-antibiotic regimens used for carbapenem-resistant Klebsiella growths, as well as exploring the association of factors such as gestational age and age at sepsis diagnosis of patients with their outcomes post-treatment with CAZ-AVI± ATM.
METHODOLOGYThis is a retrospective cohort study of admitted patients in a neonatal intensive care unit of a tertiary hospital with MDR Klebsiella hospital-acquired sepsis across a two-year period. A review of medical records was done, and data were collected and analyzed.
RESULTSThere were a total 11 patients treated with CAZ-AVI ± ATM compared with 11 patients given other 2nd line antibiotic treatment regimens. The use of CAZ-AVI ± ATM exhibited a trend towards a decreased mortality rate (54.5%, p = 0.17), shorter length of hospital stays from treatment initiation (30.7 days, p = 0.50), and increased bacteriological eradication rates (63.6%, p < 0.05), compared with other 2nd line antibiotic treatment regimens, regardless of gestational age and age at sepsis diagnosis.
CONCLUSIONThe use of CAZ-AVI ± ATM showed a more favorable trend compared with other 2nd line antimicrobials for with MDR Klebsiella hospital-acquired sepsis. These observations, however, require further confirmation with a prospective study, a longer study period, and an increase in sample size.

OBJECTIVE:
This study described bronchiectasis profiles at the Philippine Children’s Medical Center (2021-2023).
MATERIALS AND METHODS:
A retrospective chart review at PCMC analyzed the demographic profile, imaging, management and outcome of patients with bronchiectasis enrolled in the Chronic Lung Disease Program from 2021-2023.
Results:
Twenty seven patients were included in this study. Most patients were diagnosed after the age of six and showed female predominance. The most common symptom at the time of diagnosis was chronic cough (81.5%) with pulmonary tuberculosis (51.9%) as the most common etiology. All patients were treated with cyclic azithromycin. Pseudomonas aeruginosa was the prevalent microorganism isolated in the sputum and tracheal aspirate samples of the patients (56.5%).
Conclusion
Patients with bronchiectasis were more commonly diagnosed in children past age of six with more prevalence in females. The most common symptom was chronic cough followed by fever, dyspnea and weight loss. Pulmonary tuberculosis and recurrent respiratory infections were noted to be the most common etiology with the left lower lobe most affected in HRCT. The most common phenotype seen was cystic, which is irreversible and a sign of progressive bronchiectasis, which may point to a late diagnosis. This emphasizes the need for physicians to have a high index of suspicion in patients with chronic or recurrent respiratory symptoms. All patients were treated with an oral macrolide with 25-31% of patients with decreased and/or absent symptoms. Pseudomonas aeruginosa was the prevalent microorganism isolated in the sputum and tracheal aspirate samples of the patients, which should be taken into account when treating for exacerbation.

Objective:To determine the effectiveness of a one-stage hearing screening protocol in detecting hearing loss in high risk newborns at the Neonatal Intensive Care Unit of the Jose R. Reyes Memorial Medical Center.
Methods:
Design:Cross-Sectional Study
Setting:Tertiary Government Training Hospital
Population:High-risk newborns admitted at the Neonatal Intensive Care Unit of the Jose R. Reyes Memorial Medical Center from March to December 2023 underwent a one stage universal newborn hearing screening protocol. Excluded from the study were patients who were admitted for less than 48 hours, without consent from their parents or guardians and babies who were not cleared medically to undergo testing, and those who presented with aural atresia and/or any physical anomaly of the head and the external ear.
Results:A total of 169 babies were initially seen with 16 babies lost to follow up resulting in a final total of 153 babies (or 306 ears) tested. The refer and false positive rates were 9.8% and 8.92%, respectively, on average comparable to or even better than the two-step protocol in most studies. Sensitivity was determined to be 100% while specificity was 91.08%. The incidence of hearing loss in the study population was 19.8/1000, consistent with various study outcomes for high risk newborns. There was no reported incidence of auditory neuropathy in this study. The primary risk factors that were present in babies with hearing loss were: low birth weight, prematurity, neonatal intensive care unit admission of more than 5 days and exposure to ototoxic medications.
Conclusion:The one-staged Automated Auditory Brainstem Response (AABR) is an effective and efficient newborn hearing screening protocol for high-risk newborns in the Neonatal Intensive Care Unit (NICU) setting and eventually, may be considered as an alternative hearing screening technique whenever available in this cohort. More studies about improving newborn hearing screening, cost-analysis, diagnostics and interventions of hearing loss should be pursued in implementation of the Universal Hearing Screening Law in the Philippines.

We describe an unusual case of hypoxic ischemic encephalopathy in a preterm female of 36 weeks who presented with status epilepticus and atypical abdominal myoclonus. The seizures were confirmed electrographically using video electroencephalography (EEG), while the abdominal myoclonus was demonstrated to be nonepileptic, as it had no EEG correlate. Other possible causes of neonatal seizures were excluded. The infant then responded to a gamut of antiseizure medications but the myoclonus persisted. To the best of our knowledge, this is the first report of atypical myoclonus in a preterm baby caused by hypoxic ischemic encephalopathy.

INTRODUCTION:
Paediatric patients admitted to the inpatient units from the emergency department (ED) are increasing, but the mean length of stay has fallen significantly. We aimed to determine the reasons behind paediatric one-day admissions in Singapore and to assess their necessity.
METHODS:
A retrospective study involving paediatric patients who were admitted from a general ED of an adult tertiary hospital to a paediatric tertiary hospital between 1 August 2018 and 30 April 2020. One-day admission was defined as an inpatient stay of less than 24 h from the time of admission to discharge. An unnecessary admission was defined as one with no diagnostic test ordered, intravenous medication administered, therapeutic procedure performed or specialty review made in the inpatient unit. Data were captured in a standardised form and analysed.
RESULTS:
There were 13,944 paediatric attendances - 1,160 (8.3%) paediatric patients were admitted. Among these, 481 (41.4%) were one-day admissions. Upper respiratory tract infection (62, 12.9%), gastroenteritis (60, 12.5%) and head injury (52, 10.8%) were the three most common conditions. The three most common reasons for ED admissions were inpatient treatment (203, 42.2%), inpatient monitoring (185, 38.5%) and inpatient diagnostic investigations (32, 12.3%). Ninety-six (20.0%) one-day admissions were unnecessary.
CONCLUSION
Paediatric one-day admissions present an opportunity to develop and implement interventions targeted at the healthcare system, the ED, the paediatric patient and their caregiver, in order to safely slow down and perhaps reverse the trend of increased hospital admissions.

INTRODUCTION:
Preterm birth (PTB) remains a leading cause of perinatal morbidity and mortality worldwide. Understanding Singapore's PTB trends and associated risk factors can inform effective strategies for screening and intervention. This study analyses PTB trends in Singapore from 2017 to 2023, identifies risk factors in this multi-ethnic population and evaluates a predictive model for PTB.
METHOD:
A retrospective analysis of all PTBs between 22+0 and 36+6 weeks of gestation, from 1 January 2017 to 31 December 2023, was performed by extracting maternal and neonatal data from electronic medical records. These PTBs were taken from the registry of births for Singapore and SingHealth cluster data. Cochran- Armitage trend test and multinomial logistic regression were used. An extreme gradient boosting (XGBoost) model was developed to test and predict the risk of PTB.
RESULTS:
The PTB rate in Singapore did not show a significant change. However, there was modest downward trend in the SingHealth population from 11.3% to 10.2%, mainly in late spontaneous PTBs (sPTBs). sPTBs accounted for ∼60% of PTBs. Risk factors for very/extreme sPTB included Chinese ethnicity, age ≥35 years, body mass index (BMI) ≥23 kg/m2, being unmarried, primiparity, twin pregnancy and maternal blood group AB. The XGBoost model achieved an area under the receiver operating characteristic curve of 0.75, indicating moderate ability to predict PTB.
CONCLUSION
The overall PTB rate in Singapore has not improved. This study underscores the importance of local factors, particularly advanced maternal age, BMI, primiparity, unmarried, Chinese ethnicity and maternal blood group AB influencing PTB risk. Artificial intelligence methods show promise in improving PTB risk stratification, ultimately supporting personalised care and intervention.

OBJECTIVE:
Asthma imposes a significant global health burden. This study examines changes in the asthma-related disease burden from 1990 to 2021 and projects future burdens for 2050 under different scenarios.
METHODS:
Using data from the Global Burden of Disease 2021 study, we analyzed asthma incidence, prevalence, mortality, and disability-adjusted life years (DALYs) from 1990 to 2021. We projected the disease burden for 2050 based on current trends and hypothetical scenarios in which all risk factors are controlled. Temporal trends in age-standardized incidence, prevalence, mortality, and DALY rates were explored using Annual Percent Change.
RESULTS:
In 2021, the age-standardized rates for asthma incidence, prevalence, mortality, and DALYs in China were 364.17 per 100,000 (95% uncertainty interval [ UI]: 283.22-494.10), 1,956.49 per 100,000 (95% UI: 1,566.68-2,491.87), 1.47 per 100,000 (95% UI: 1.15-1.79), and 103.76 per 100,000 (95% UI: 72.50-145.46), respectively. A higher disease burden was observed among Chinese men and individuals aged 70 years or older. Compared to the current trend, a combined scenario involving improvements in environmental factors, behavioral and metabolic health, child nutrition, and vaccination resulted in a greater reduction in the disease burden caused by asthma.
CONCLUSION
Addressing modifiable risk factors is essential for further reducing the asthma-related disease burden.
