It was found that both statistical models have similar performance when analyzing residual analysis results, root mean square error of cross-validation, and final accuracy and residual standard deviation, these responses being related to the regionalization of the study area and to the Box-Jenkins presents strong, homogeneous, and stable correlations in the time series modeled for each pixel.The aim of this study was to assess whether home phototherapy was feasible and safe in a cohort of otherwise healthy term-born neonates who fulfilled the criteria for in-hospital phototherapy. This was a randomized controlled trial in which term newborns with a total serum bilirubin of 18-24 mg/dL (300-400 μmol) were randomized to either home phototherapy or conventional in-hospital phototherapy. The primary outcome measurements were safety and efficacy, length of stay and the number of failed treatments. The secondary outcomes were the number of blood samples and weight gain during treatment. One hundred forty-seven patients were recruited, 69 patients randomized to conventional phototherapy and 78 to home phototherapy. The results showed that no patients needed blood exchange and only 4% of the patients allocated to home phototherapy were admitted to the hospital. The duration of phototherapy, length of stay, amount of blood tests and weight change showed no statically significant differences.Conclusion Home phototherapy could be a safe alternative to inpatient phototherapy for otherwise healthy newborns with hyperbilirubinemia if daily checkups and 24/7 telephone support can be provided. The parents should be informed to contact the hospital immediately if they fail to perform the treatment at home.Trial registration Clinicaltrials.gov NCT03536078 What is Known • Phototherapy in the hospital is a safe and effective treatment without major side effects. • Fibre optic equipment has made the choice of home phototherapy possible. What is New • This is the first randomized controlled trial comparing home phototherapy with hospital phototherapy. • Results indicate that home phototherapy could be considered as a safe and feasible alternative when performed according to instructions given, to hospital treatment for otherwise healthy term newborns.From clinical practice, we noted that a subset of neonates with hyperinsulinism develop conjugated hyperbilirubinemia. A relationship between these two conditions has not been previously described. We aimed to assess the incidence of cholestasis in a cohort of neonates with hyperinsulinism and describe their clinical characteristics. In a retrospective cohort of 63 neonates with hyperinsulinism, 48% developed cholestasis (conjugated bilirubin > 17 μmol/L) with a median maximum conjugated bilirubin of 81 [21 to 191] μmol/L. A history of fetal distress (RR 2.3 [1.24-4.45], p less then 0.01) and prematurity (RR 2.0 [1.23-3.26], p less then 0.01) was associated with the development of cholestasis, but not parental nutrition or other pharmacological treatments. An underlying etiology for the cholestasis was only found in 1 patient, and in all cases the cholestasis spontaneously improved.Conclusions A significant percentage of infants with hyperinsulinism develop idiopathic, spontaneously resolving, conjugated hyperbilirubinemia. selleck chemicals llc The association with a history of fetal distress potentially suggests that intrauterine factors leading to hyperinsulinism may also predispose towards conjugated hyperbilirubinemia. While the presence of neonatal cholestatic jaundice warrants timely investigations to exclude important underling etiologies, if validated, these findings may support a less invasive diagnostic workup of conjugated hyperbilirubinemia in infants with co-existent hyperinsulinism. What is Known • Hyperinsulinism and conjugated hyperbilirubinemia are two common presentations in neonates. • A clinical association between the two conditions has not been described. What is New • A significant proportion of infants with hyperinsulinism develop idiopathic, spontaneously resolving conjugated hyperbilirubinemia. • Increased risk for cholestasis in this patient population is associated with fetal distress and prematurity but not parental nutrition.The study of protein-solid surface binding as well as blocking efficiency of blocking agents plays an important role in the development of high-performance immunoassays. Although conventional colorimetric based assays are widely employed to monitor protein non-specific binding on the surface of microplate wells and evaluate the performance of blocking agents, there is still a great need to develop new methods to achieve the same goal from a new perspective. In this study, an innovative whole area scanning (WAS)-enabled direct-counting strategy was developed and validated through studying the blocking efficiency of different blocking agents on the non-specific binding of streptavidin-alkaline phosphatase conjugate (Strep-ALP, a model protein) to the surface of 96-well microplates. After non-specific binding of Strep-ALP in wells with or without blocking agents' treatment and loading of ELF™ 97 phosphate (ELFP), ALP in Strep-ALP conjugates converts ELFP to water-insoluble ELF™ 97 alcohol (ELFA), which precipitates locally, self-assembles into large needle structures, and glows green fluorescence upon excitation. After quenching the reaction, WAS of the whole wells allows us to directly count the number of individual fluorescent precipitates, which can be used to calculate and compare the blocking efficiency of three commonly used blocking agents (BSA, casein, and dry milk) based on mitigating the non-specific binding of Strep-ALP. WAS-enabled counting of individual needle-type precipitates opens a new avenue to investigate protein-solid surface binding as well as the efficiency of blocking agents with high sensitivity.In this study, a novel method which involved in-tube solid-phase microextraction (SPME) using an attapulgite (ATP) nanoparticles-based hydrophobic monolithic column was successfully developed. It was coupled with high-performance liquid chromatography-ultraviolet detection for the determination of three phosphodiesterase-5 (PDE-5) inhibitors, including thiosildenafil, pseudovardenafil, and norneosildenafil, in functional foods. The monolithic column was prepared by one-step polymerization, using 3-trimethoxysilylpropyl methacrylate-modified ATP nanoparticles and 1-butyl-3-vinylimidazolium bromide (VBIMBr) as the functional monomers, and ethylene glycol dimethacrylate (EDMA) as the cross-linker. The obtained poly(ATP-VBIMBr-EDMA) monolith was characterized by scanning electron microscopy equipped with energy-dispersive analysis of X-ray, Fourier transform infrared spectroscopy, thermogravimetric analysis, and X-ray diffraction. The adsorption capacity, up to 2.00 μg/cm calculated by the Langmuir isotherm model, was about six times that of the poly(VBIMBr-EDMA) monolith.
