Revised dose schema of sublingual buprenorphine in the treatment of the neonatal opioid abstinence syndrome.

AIMS: More than half of infants exposed to opioids in utero develop neonatal abstinence syndrome (NAS) of severity to require pharmacological therapy. Current treatments are associated with prolonged hospitalization. We sought to optimize the dose of sublingual buprenorphine in the treatment of NAS. DESIGN: Randomized, Phase 1, open-label, active-control clinical trial comparing sublingual buprenorphine to oral morphine. SETTING: Large, urban, tertiary care hospital. PARTICIPANTS: Twenty-four term infants requiring pharmacological treatment for NAS. MEASUREMENTS: Outcomes were neonatal safety, length of treatment and length of hospitalization. FINDINGS: Sublingual buprenorphine was safe and effective. Infants treated with buprenorphine had a 23-day length of treatment compared to 38 days for those treated with morphine (P = 0.01), representing a 40% reduction. Length of hospital stay in the buprenorphine group was reduced 24%, from 42 to 32 days (P = 0.05). CONCLUSIONS: Sublingual buprenorphine was safe in NAS, with a substantial efficacy advantage over standard of care therapy with oral morphine

Clinical Presentation and Treatment of Transfusion-Associated Babesiosis in Premature Infants

We review here 7 cases of neonatal transfusion-associated babesiosis at a NICU in the northeast United States. Transfusion from 2 infected units of blood resulted in the 7 cases described. The clinical presentation was highly variable in this cohort; the extremely low birth weight neonates were the most severely affected. Antibiotic therapy was effective in neonates with mild and asymptomatic infection; however, double-volume exchange blood transfusion with prolonged multidrug treatment was required for the 2 most severe cases. The risk of Babesia microti infection is not eliminated through current blood-bank practices. Neonatologists in endemic areas should have a high index of suspicion for babesiosis in premature infants exposed to blood transfusions.</jats:p

Chromosome-specific subsets of human alphoid DNA identified by a chromosome 2-derived clone

We have cloned an alphoid DNA fragment, pBS4D, from the DNA of a human-hamster hybrid cell line containing chromosome 2 as its only cytologically detectable human component. Under high stringency conditions, pBS4D hybridized in situ mostly to chromosome 2 and to a lesser extent to chromosomes 18 and 20. Restriction analysis using the DNA from selected somatic hybrid cell lines revealed that the genomic organization of this alphoid DNA differs on each of these three chromosomes

Nurses’ experiences of caring for preterm infants in pain: A meta-ethnography

Objective: Preterm infants are subjected to numerous painful procedures during their neonatal intensive care unit (NICU) hospitalization. Despite advancements in pain alleviation, nurses remain challenged to provide timely and effective pain management for preterm infants. Greater understanding of the lived experience of nurses caring for preterm infants in pain could provide novel insights to improve pain management for this vulnerable population. The aim of this meta-ethnography was to synthesize and interpret qualitative findings of nurses’ experiences of taking care of preterm infants in pain. Methods: An extensive literature search in PubMed, CINAHL, PsycINFO, Scopus, BIOSIS and ProQuest Dissertation and Theses Database was conducted, including studies within the past 10 years. Two nursing researchers conducted data extraction and analysis independently. Inclusion criteria were applied to search for qualitative studies of nurse participants who worked in the NICU taking care of preterm infants. Studies published in a language other than English, articles that did not include qualitative data and qualitative data that could not be extracted from the findings or did not discuss nurses’ experiences were excluded. Critical Appraisal Skills Programme was used for literature quality evaluation. Results: Eight studies remained after further screening according to inclusion and exclusion criteria. These eight studies were conducted from 2013 to 2018 and totally enrolled 205 nurses from Iran, Canada, the United States, Finland, Sweden, Switzerland, and Australia. Five themes emerged on the nurses’ perspectives of taking care of preterm infants in pain: 1) They sense the neonatal pain; 2) Adverse consequences of unrelieved pain; 3) Barriers of managing pain; 4) Concerns of available approaches for pain relief; 5) Failure to work with parents. Conclusions: This meta-ethnography identified nurses’ understanding of pain in preterm infants that can be assessed, and they acknowledged that unrelieved pain could cause developmental deficits in infants. The barriers are lack of training and support on pain assessment and intervention in preterm infants. Optimizing workload and environment, developing age-specified pain assessment and intervention, receiving emotional support and training, and building up a rapport with parents are urgent needs for nurses to provide better care to infants having pain
