In Japan, the mortality rate of extremely low birth weight (ELBW) infants is notably in comparison with other developed countries, but prevalence chronic lung disease (CLD) and retinopathy prematurity (ROP) relatively high. This study aimed to estimate morbidity ELBW born 2015 who were admitted neonatal intensive care units (NICUs) Japan examine factors that affected short-term outcomes these infants. We also compared 2005, 2010, 2015.We analyzed mortality, morbidity, related infants, using...

Acute kidney injury (AKI) has been reported to occur in 30–70% of asphyxiated neonates. Hydrogen (H2) gas became a major research focus neonatal medicine after the identification its robust antioxidative properties. However, ability H2 ameliorate AKI is unknown. We examined histopathological injuries piglet renal cortex on day 5 hypoxic-ischemic (HI) insult and if can alleviate injuries. Twenty piglets were divided into three groups: no (Control, n = 6), HI alone (HI, 8), with ventilation...

Abstract Therapeutic drug monitoring is generally unnecessary in caffeine treatment for apnea of prematurity, as serum concentrations preterm infants are normally markedly lower than those at which intoxication occurs. However, several studies have reported having developed toxicity. This retrospective observational study, conducted a tertiary center Kagawa, Japan, aimed to evaluate the correlation between maintenance dose and determine leading suggested toxic levels. We included 24...

The antiviral and antibacterial properties of ozone gas have been utilised for air on-site disinfection. However, excess exposure is toxic to humans, necessitating the monitoring levels. While this has achieved using indicators, determining levels at intermediate time points during remains challenging owing current ones being capable measuring only endpoints. Shifts in endpoint are also difficult as coverage ranges indicators dependent on a single colour dye. indicator that covers wide range...

Perinatal hypoxic-ischemic brain injury of neonates remains a significant problem worldwide. During the resuscitation period, changes in cerebral hemoglobin oxygen saturation (ScO2) have been identified by near-infrared spectroscopy (NIRS). However, asphyxiated neonates, relationship between these and is not known. Three-wavelength time-resolved spectroscopy, an advanced technology for NIRS, allows estimation ScO2 blood volume (CBV). Here, we studied CBV during period after insult...

Neonatal hypoxic-ischemic encephalopathy (HIE) is a significant cause of neonatal mortality and developmental disabilities. It has been revealed that the temporal behavior cerebral blood volume (CBV) carries information on degree hypoxia-ischemia. CBV can be estimated by means near-infrared spectroscopy. The change after insult related to during insult. In this paper, we consider mathematical model which governs time evolution We show predicted with Kalman filter based model.
