Neonatal intensive care unit admissions before and after the adoption of the baby friendly hospital initiative.

BACKGROUND: The Baby Friendly Hospital initiative (BFHI) is a global initiative of the World Health Organization developed in 1991 to promote and support successful breastfeeding. It has led to increased rates of exclusive breastfeeding. Exclusive breastfeeding may increase risk for hypoglycemia, hyperbilirubinemia, and dehydration requiring higher level of neonatal care. OBJECTIVE: To determine if there was a change in admissions to the Neonatal Intensive Care Unit (NICU) from the newborn nursery after the adoption of BFHI in a large urban hospital. METHODS: This is a retrospective analysis of all neonates admitted to the NICU from the newborn nursery between January 2007 and December 2016 at Thomas Jefferson University Hospital, in Philadelphia, PA, USA. Demographics, clinical characteristics and primary diagnosis for admission were compared between those admitted before (January 2007 to December 2011) and after (January 2012 to December 2016) the initiation of BFHI. RESULTS: A total of 20,124 infants were born and 3,684 infants (18.3%) were admitted to NICU. 570 infants (2.8% of live birth) were admitted to the NICU from the newborn nursery, 282 (49.5%) were born before and 288 (50.5%) born after BFHI. There was no significant difference in the number of infants admitted from the newborn nursery either as a percentage of total deliveries (2.8 versus 2.9%, p = .6) or percentage of total NICU admissions (15.5 versus 15.5%, p = 1.0) before and after the BFHI. Additionally, there was no difference in number of infants admitted with a diagnosis of possible sepsis, hypoglycemia, neonatal abstinence syndrome (NAS) and hyperbilirubinemia between the two groups. However, significantly more infants admitted with hypoglycemia required IV fluids for hypoglycemia after the initiation of BFHI (8 out of 27 versus 21 out of 28, p .001). The age of admission was higher and the duration of NICU stay was shorter in infants admitted after the initiation of the BFHI. CONCLUSIONS: The BFHI has not led to a significant change in the number of infants admitted to NICU from the newborn nursery or reasons for their admissions. However, since its adoption, there has been an increase in the use of IV fluids for treatment of hypoglycemia. These findings suggest a role for additional treatments other than formula to prevent IV fluid use, such as glucose gel. Change in NICU guidelines for the management of possible sepsis and NAS may have impacted the duration of hospitalization in infants born after BFHI.

Knockdown of epigenetic transcriptional co-regulator Brd2a disrupts apoptosis and proper formation of hindbrain and midbrain-hindbrain boundary (MHB) region in zebrafish.

Brd2 is a member of the bromodomain-extraterminal domain (BET) family of proteins and functions as an acetyl-histone-directed transcriptional co-regulator and recruitment scaffold in chromatin modification complexes affecting signal-dependent transcription. While Brd2 acts as a protooncogene in mammalian blood, developmental studies link it to regulation of neuronal apoptosis and epilepsy, and complete knockout of the gene is invariably embryonic lethal. In Drosophila, the Brd2 homolog acts as a maternal effect factor necessary for segment formation and identity and proper expression of homeotic loci, including Ultrabithorax and engrailed. To test the various roles attributed to Brd2 in a single developmental system representing a non-mammalian vertebrate, we conducted a phenotypic characterization of Brd2a deficient zebrafish embryos produced by morpholino knockdown and corroborated by Crispr-Cas9 disruption and small molecule inhibitor treatments. brd2aMO morphants exhibit reduced hindbrain with an ill-defined midbrain-hindbrain boundary (MHB) region; irregular notochord, neural tube, and somites; and abnormalities in ventral trunk and ventral nerve cord interneuron positioning. Using whole mount TUNEL and confocal microscopy, we uncover a significant decrease, then a dramatic increase, of p53-independent cell death at the start and end of segmentation, respectively. In contrast, using qualitative and quantitative analyses of BrdU incorporation, phosphohistone H3-tagging, and flow cytometry, we detect little effect of Brd2a knockdown on overall proliferation levels in embryos. RNA in situ hybridization shows reduced or absent expression of homeobox gene eng2a and paired box gene pax2a, in the hindbrain domain of the MHB region, and an overabundance of pax2a-positive kidney progenitors, in knockdowns. Together, these results suggest an evolutionarily conserved role for Brd2 in the proper formation and/or patterning of segmented tissues, including the vertebrate CNS, where it acts as a bi-modal regulator of apoptosis, and is necessary, directly or indirectly, for proper expression of genes that pattern the MHB and/or regulate differentiation in the anterior hindbrain.

Incidence and severity of pancreatogenic diabetes after pancreatic resection.

BACKGROUND: While many patients experience prolonged survival after pancreatic resection for benign or malignant disease, the long-term risk of pancreatogenic diabetes mellitus (DM) remains poorly characterized. METHODS: One thousand one hundred seven patients underwent pancreatectomy at Thomas Jefferson University between 2006 and 2013. Attempts were made to contact all living patients by telephone and a DM-focused questionnaire was administered. RESULTS: Two hundred fifty-nine of 691 (37 %) surviving patients completed the survey, including 179 pancreaticoduodenectomies (PD), 78 distal pancreatectomies (DP), and 2 total pancreatectomies. In the PD group, 44 (25 %) patients reported having DM prior to resection. Of these, 5 (12 %) had improved glucose control after resection and 21 (48 %) reported escalated DM medication requirements post-resection. Of 135 PD patients without preoperative DM, 24 (18 %) had new-onset DM postoperatively. In the DP group, 23 patients (29 %) had DM preoperatively. None had improved glucose control after resection, while six (26 %) had worse control after resection. Seventeen of 55 DP patients (31 %) without preoperative DM developed new-onset DM postoperatively (p = 0.04 vs. PD). Preoperative HgbA1C >6.0 %, glucose >124 mg/dL, and insulin use >2 units per day were associated with an increased risk of new-onset postoperative DM. CONCLUSIONS: The development or worsening of DM after pancreatic resection is extremely common, with different types of resections conveying different risks for disease progression. DP places patients at a greater risk for the development of new-onset postoperative diabetes when compared to PD. In contrast, patients with preoperative diabetes are more likely to experience worsening of their disease after PD as compared to DP. Patients should be screened prospectively, particularly those at highest risk, and informed of and educated about the potential for post-resection DM.
