Objective: To evaluate the correlation between total serum and transcutaneous bilirubin and to determine the reliability of transcutaneous bilirubinometry for screening and monitoring of neonatal jaundice among preterms.

Study Design: Ninety nine infants with gestational ages ≤34 weeks were prospectively enrolled. Babies were classified into three groups as; 24-28, 29-31, and 32-34 weeks. Total serum bilirubin and simultaneous transcutaneous bilirubin were measured before the onset of phototheraphy, during and at 24 h after discontinuing phototherapy.

Results: Total serum bilirubin significantly correlated with transcutaneous bilirubin in the whole cohort (r = 0.867, p < 0.001) and in each group before, during and after phototheraphy. Hypotension was the only variable which effects the difference between two methods at postnatal first day of life (p = 0.039).

Conclusion: Transcutaneous bilirubin levels were highly correlated with total serum bilirubin levels even in 24-28 GW babies. Transcutaneous bilirubin may be useful for screening and monitoring of jaundice in very preterm newborns.

Background Aims: Hypophosphatemia has been recently recognized adverse event in chimeric antigen receptor (CAR)-T cell therapy, complicating 70-75% of patients. Severe hypophosphatemia can cause cytokine release syndrome (CRS)-like symptoms, such as respiratory and cardiovascular dysfunction. Some reports have described the association between inorganic phosphate (iP) and CRS in patients treated with tisagenlecleucel (tisa-cel), lisocabtagene maraleucel (liso-cel), axicabtagene ciloleucel (axi-cel).

: Zika disease is caused by the Zika virus (ZIKV) and represents a major public health problem because of the complications in newborn babies from mothers who were infected during pregnancy. It is estimated that 80% of infected pregnant women are asymptomatic, which complicates the identification of infected individuals. In this study, we aimed to detect ZIKV in asymptomatic pregnant women and the effects in the newborns were analyzed.
