BackgroundThis study compares the minimally invasive Bilistick and a noninvasive method with standard Total Serum Bilirubin (TSB) measurement in preterm newborns receiving phototherapy. We assess the agreement of Transcutaneous Bilirubinometer (TcB) and Bilistick bilirubin measurements with standard TSB measurement in preterm infants receiving phototherapy.MethodsBilirubin was measured by using TcB and Bilistick in 94 preterm infants in RSCM Jakarta Neonatal Ward from October 2016 to March 2017, with gestational ages of < 35 weeks, before phototherapy and after 24 and 48 h of phototherapy.ResultsThere was significant correlation before, at 24 and 48 h of phototherapy between TSB and either TcB (r = 0.874; r = 0.889; r = 0.878 respectively; p < 0.0001), or Bilistick (r = 0.868; r = 0.877; r = 0.918 respectively; p < 0.0001). The mean difference and limits of agreement before, at 24 and 48 h of phototherapy between TcB and TSB were 0.81 ± 1.51 mg/dL (− 2.14 to 3.77 mg/dL); 0.43 ± 1.57 mg/dL (− 2.66 to 3.51 mg/dL); 0.41 ± 1.58 mg/dL (− 2.69 to 3.50 mg/dL), respectively. For Bilistick they were − 1.50 ± 1.47 mg/dL (− 4.38 to 1.38 mg/dL); − 1.43 ± 1.47 mg/dL (− 4.32 to 1.46 mg/dL); − 1,15 ± 1.31 mg/dL (− 3,72 to 1,42 mg/dL), respectively.ConclusionsBoth methods are reliable for measuring TSB before, during, and after phototherapy in preterm infants. TcB tends to overestimate while Bilistick underestimates TSB.

Background: Indonesia has a high number of COVID-19 cases and mortalities relative to not only among the Asia Pacific region but the world. Children were thought to be less affected by the virus compared to adults. Most of the public data reported combined data between adults and children. The Indonesian Pediatric Society (IPS) was involved in the COVID-19 response, especially in the area of child health. One of IPS's activities is collecting data registries from each of their chapters to provide a better understanding of COVID-19 in children.Objective: The objective of this study was to share the data of suspected and confirmed COVID-19 cases in children from IPS's COVID-19 data registry.Method: This is a retrospective study from the IPS's COVID-19 registry data. We collected the data of COVID-19 in children during March to December 2020 from each of the IPS chapters. We analyzed the prevalence, case fatality rate (CFR), age groups, diagnosis, and comorbidities of the children diagnosed with COVID-19.Result: As of December 21, 2020, there were 35,506 suspected cases of children with COVID-19. In total, there were 522 deaths, with a case fatality ratio (CFR) of 1.4. There were 37,706 confirmed cases with 175 fatalities (CFR 0.46). The highest mortality in confirmed COVID-19 cases was from children ages 10–18 years (42 out of 159 cases: 26%). The most common comorbidity and diagnosis found were malignancy (17.3%) and respiratory failure (54.5%).Conclusion: The CFR of confirmed COVID-19 cases in children in Indonesia is high and should be a major public concern.
