Father newborn skin-to-skin wheelchair transfer from delivery room to neonatal care unit: Possible change in practices.

OBJECTIVE: To evaluate the transfer of newborns from the delivery room to the neonatal care unit with their fathers on wheelchairs in terms of the safety of the procedure and paternal anxiety. METHODS: A prospective observational single-center before-and-after pilot study was conducted from February to May 2018 at the University Maternity Hospital of Nantes. Safe transfer was judged on the basis of episodes of hypothermia or hypoglycemia. Paternal anxiety was assessed with the State-Trait Anxiety Inventory (STAI) scale after newborn transfer. RESULTS: Overall, 70 preterm newborns were enrolled, 44 were carried in wheelchairs in the father's arms (target group) and 26 were transferred in an incubator (control group). After adjusting for gestational age and birthweight, there were no statistically significantly differences between the target and the control group in the rates of hypothermia (43.9% vs 30.8%, p = 0,59) and hypoglycemia (9.52% vs 19.23%, p = 0,19). The STAI scale score was not significantly different between groups after incubator transfer or wheelchair transfer, at 35 ± 8.2 and 38 ± 10.2, respectively (p = 0.07). CONCLUSION: Transferring a newborn to the neonatal care unit via wheelchair with the father is a safe alternative to incubator transfer.

BH3-only protein Bik is involved in both apoptosis induction and sensitivity to oxidative stress in multiple myeloma.

BACKGROUND: although gene expression profile of multiple myeloma (MM) patients shows a wide range of Bik/Nbk expression, varying from absent to high, its regulation and function in myeloma cells is poorly understood. Thus, we addressed these questions in MM. METHODS: human myeloma cell lines (HMCLs) and primary purified myeloma cells were studied for Bcl-2 family protein expression by western blot and further correlation analysis was performed. Correlative study between Bik and thyrotroph embryonic factor (TEF) transcription factor expression was analysed by PCR. Stress oxidative response was analysed by flow cytometry. RESULTS: a strong expression of Bik protein was found only in one out of three of HMCL and correlated to Bcl-2 expression (P=0.0006). We demonstrated that Bik could be regulated at the protein level by Bcl-2 and at the transcriptional level by TEF. Bik overexpression sensitises myeloma cells to oxidative stress whereas Bik silencing increases resistance to H(2)O(2) oxidative stress. Furthermore, Bik ectopic expression disrupts Bim/Bcl-2 and Bim/Bcl-xL endogenous complexes triggering Bim release that could induce Bax and Bak activation. CONCLUSIONS: ours results suggest that Bik has a role in both, apoptosis induction and sensitivity to oxidative stress in myeloma cells. Small BH3 mimetic molecules should be considered for further apoptosis-based therapy in myeloma cells expressing endogenous Bik/Bcl-2 complexes.

A 1-year survey of catheter-related infections in a pediatric university hospital: A prospective study.

BACKGROUND: Central venous catheters (CVCs) provide a great comfort for hospitalized children. However, CVCs increase the risk of severe infection. As there are few data regarding pediatric epidemiology of catheter-related infections (CRIs), the main objective of this study was to measure the incidence rate of CRIs in our pediatric university hospital. We also sought to characterize the CRIs and to identify risk factors. MATERIALS AND METHODS: We conducted an epidemiological prospective monocentric study including all CVCs, except Port-a-Caths and arterial catheters, inserted in children from birth to 18 years of age between April 2015 and March 2016 in the pediatric University Hospital of Nantes. Our main focus was the incidence rate of CRIs, defined according to French guidelines, while distinguishing between bloodstream infections (CRBIs) and non-bloodstream infections (CRIWBs). The incidence rate was also described for each pediatric ward. We analyzed the association between infection and potential risk factors using univariate and multivariate analysis by Cox regression. RESULTS: We included 793 CVCs with 60 CRBIs and four CRIWBs. The incidence rate was 4.6/1000 catheter-days, with the highest incidence rate occurring in the neonatal intensive care unit (13.7/1000 catheter-days). Coagulase-negative staphylococci were responsible for 77.5% of the CRIs. Factors independently associated with a higher risk of infection in neonates were invasive ventilation and low gestational age. CONCLUSIONS: The incidence of CRIs in children hospitalized in our institution appears to be higher than the typical rate of CRIs reported in the literature. This was particularly true for neonates. These results should lead us to reinforce preventive measures and antibiotic stewardship but they also raise the difficulty of diagnosing with certainty CRIs in neonates.
