OBJECTIVE:
To elucidate the epidemiological characteristics and genetic variant profile of Short-chain acyl-CoA dehydrogenase deficiency (SCADD) among newborns from Hainan Province and evaluate its significance within the local neonatal disease screening panel.
METHODS:
A total of 84 184 newborns born in Hainan Province from February to December 2024 were included. Tandem mass spectrometry (MS/MS) was employed to detect butyrylcarnitine (C4) and propionylcarnitine (C3) levels in dried blood spots. Screening thresholds were set at C4 > 0.43 μ mol/L and C4/C3 ratio > 0.28. Suspected cases underwent confirmatory testing via urinary ethylmalonic acid analysis by gas chromatography-mass spectrometry and whole-exome sequencing for ACADS gene variants. This study was approved by the Medial Ethics Committee of the hospital (Ethics No.: HNWCMC-2024-55).
RESULTS:
Six SCADD cases (male-to-female ratio = 1:1) were diagnosed, with all carrying compound heterozygous variants at two loci, yielding a prevalence of 7.13 per 100,000 live births. Four known ACADS gene variants were identified, with both c.322G>A and c.625G>A detected at a frequency of 41.7%. Regular follow-up (as of January 2026) revealed that all diagnosed cases have remained asymptomatic with normal growth and development.
CONCLUSION
The prevalence of SCADD among newborns in Hainan Province is relatively high, with c.322G>A and c.625G>A as the hotspot variants in the region. Given the absence of clinical phenotypes in all screen-detected cases during long-term follow-up, it is recommended to remove this condition from the routine neonatal screening program for this region to reduce unnecessary anxiety and medical cost.

BACKGROUND AND OBJECTIVE
Transient congenital hypothyroidism (TCH) refers to temporary deficiency of thyroid hormone identified after birth which later recovers to improved thyroxine production. Its prevalence in the Philippines has not been reported in a large-scale study. Its diagnosis remains difficult due to its numerous possible etiologies. Identifying the predictive factors of TCH may aid in earlier diagnosis and decreased risk of overtreatment. This study aimed to determine the predictive factors for TCH in children with congenital hypothyroidism (CH) detected by newborn screening (NBS) in the Philippines from January 2010 to December 2017.
METHODSIn this multicenter retrospective cohort study involving 15 NBS continuity clinics in the Philippines, medical records were reviewed, and clinical and laboratory factors were compared between children with TCH and those with permanent congenital hypothyroidism (PCH). Of the 2,913 children diagnosed with CH in the Philippines from 2010 to 2017, 1,163 (39.92%) were excluded from the study due to an unrecalled or lost to follow-up status, or a concomitant diagnosis of Down Syndrome.
RESULTSAmong the 1,750 patients included in analysis, 6.97% were diagnosed with TCH, 60.80% were female, mean gestational age at birth was 38 weeks, and mean birth weight was 2,841 grams. Confirmatory thyrotropin (TSH) was lower and confirmatory free thyroxine (FT4) was higher in the TCH group compared to those with PCH (TSH 32.80 vs 86.65 µIU/mL [p < 0.0001]; FT4 9.90 vs 7.37 pmol/L [p 0.001]). The TCH group required lower L-thyroxine doses compared to the PCH group at treatment initiation and at 1, 2, and 3 years of age (initial 6.98 vs 12.08 µg/ kg/day [p < 0.0001]; at 1 year 1.89 vs 4.11 µg/kg/day [p < 0.0001]; at 2 years 1.21 vs 3.72 µg/kg/day [p < 0.0001]; at 3 years 0.83 vs 3.45 µg/kg/day [p < 0.0001]). Among those with TCH, mean serum TSH decreased significantly after treatment with L-thyroxine (32.80 vs. 6.55 µIU/ mL, p 0.0001). Other factors associated with TCH were results of thyroid ultrasonography (p 0.007), gestational age at birth (p 0.02), and maternal history of thyroid illness (p < 0.0001).
CONCLUSIONOf all the patients with confirmed congenital hypothyroidism via the newborn screening, 6.97% were diagnosed with transient CH. Factors associated with TCH are confirmatory TSH and FT4, L-thyroxine dose requirements, thyroid ultrasound findings, gestational age at birth, and a maternal history of thyroid illness.

BACKGROUND
End-stage renal disease (ESRD) has been increasing in prevalence in recent years. The true prevalence of depression in hemodialysis patients is still not known. Cross-cultural studies showed prevalence ranging from 20-90%. Dimaano translated the Beck’s Depression Inventory Scale into the Visayan language and used this as a screening tool for depression among hemodialysis patients - and this was the first cross-cultural translation of the Beck’s Depression Inventory Scale to the Visayan language (BDI-Visayan).
GENERAL OBJECTIVEDetermine the accuracy of Beck’s Depression Inventory - Visayan in screening for Major Depressive Disorder (MDD) among Visayan-speaking ESRD patients.
STUDY DESIGNCross-sectional survey
STUDY POPULATION AND SETTINGAdult Visayan-speaking patients, ≥ 18 years old with ESRD, with GFR < 15 ml/min/1.73 m2 and ongoing hemodialysis for at least 3 months at the Chong Hua Hospital Mandaue Renal Unit.
METHODOLOGYThe 73 subjects underwent both the BDI-Visayan and the Structured Clinical Interview for DSM Disorders. Data was gathered to determine the accuracy of the BDI-Visayan in detecting Major Depressive Disorder.
RESULTSOf the 73 subjects, 19.2% were identified with MDD, based on the SCID, while 37.0% were identified as depressed using the BDI-Visayan. Analyzed data showed that the accuracy of BDI-Visayan to detect MDD was 67.75%, with a sensitivity of 57.14%, and specificity of 67.8%.
CONCLUSIONBDI-Visayan had an acceptable accuracy in screening for MDD, however, it may tend to have an overdiagnosis in the ESRD population – emphasizing its role as a screening tool for suspected MDD cases.

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.

In recognition of the morbidity and mortality associated with human immunodeficiency virus (HIV), the Joint United Nations Programme on HIV/acquired immunodeficiency syndrome (AIDS) (UNAIDS) aims to end the epidemic by setting and striving to achieve the ambitious 95-95-95 targets. However, Singapore is still not performing well in the first UNAIDS target. The National HIV Programme (NHIVP) developed this set of recommendations based on an adaptation of major international guidelines from the World Health Organization and the US Centers for Disease Control and Prevention. The goals of this recommendation are: (1) to increase the uptake of HIV testing; (2) to allow earlier detection and identification of individuals with unrecognised HIV infection; (3) to facilitate linkage to clinical services; and (4) reduce further transmission of HIV infection in Singapore.

Annals of the Academy of Medicine, Singapore 2025;54(8):498-504
INTRODUCTION:
The high prevalence and mortality rates of breast cancer and lung cancer in Singapore necessitate robust screening programmes to enable early detection and intervention for improved patient outcomes, yet 2024 uptake and coverage remain suboptimal. This narrative review synthesises expert perspectives from a recent roundtable discussion and proposes strategies to advance breast cancer and lung cancer screening programmes.
METHOD:
A 2024 roundtable convened clinical practitioners, health policymakers, researchers and patient advocates discussed current challenges and opportunities for improving cancer screening in Singapore. Perspectives and insights were analysed to identify themes related to existing programme gaps, opportunities for innovation and implementation challenges.
DISCUSSION:
Singapore's national breast cancer screening programme has been in place for over 2 decades, yet screening uptake remains suboptimal. A national lung cancer screening programme, in contrast, is still in its early stages of implementation. Regardless, employment of risk stratification approaches that integrate genetic, demographic and lifestyle factors could enhance screening effectiveness by identifying high-risk indivi-duals, while also taking local epidemiological trends into consideration. Integration of digital health technologies, artificial intelligence and behavioural change models can enhance cancer screening uptake and accuracy to overcome barriers such as low awareness, cultural beliefs and socioeconomic factors that contribute to low participation rates.
CONCLUSION
Key recommendations include enhancing public awareness, refining screening guidelines, expanding access and applying innovative technologies. A coordinated effort among stakeholders is crucial to continually assess and enhance screening programmes to narrow the practice-policy gap and ultimately reduce breast cancer and lung cancer burden in Singapore.
