RESUMO
OBJECTIVE: Preterm infants have a higher rate of hypoglycemia and hyperglycemia, both of which have been associated with increased neonatal morbidities. The aim of this study was to evaluate the incidence of abnormal glucose homeostasis during the first 72 hours of life and study its association with major morbidities in infants admitted to our neonatal intensive care unit (NICU). STUDY DESIGN: This was a retrospective single-center study. We extracted demographic, maternal, and patient information and blood glucose levels for the first 72 hours of life for all infants with birth weight ≤1,000 g admitted to the NICU from January 2017 to December 2019. Continuous data were presented as mean ± standard deviation or as median with interquartile range. Categorical data were presented as frequency and percentage. Student's t-tests and Mann-Whitney U test were used to analyze continuous data and chi-squared test or Fisher's exact test were used to analyze categorical data. Logistic regression analysis was performed to study the relation between hyperglycemia and various morbidities after controlling for gestational age (GA). Statistical significance was set at p < 0.05. RESULTS: Of the 235 infants included in the study, 49% were hypoglycemic at admission to the NICU. Infants that were small for GA and those with history of maternal ß-blocker use had a higher incidence of hypoglycemia. Hypoglycemia at admission was not associated with increased mortality or any major morbidities. Seventy-three percent infants who were hypoglycemic or euglycemic at birth developed iatrogenic hyperglycemia during the first 72 hours of life. The incidence of retinopathy of prematurity (ROP) and severe ROP was higher in infants with hyperglycemia on univariate analysis. However, on multivariate analysis, after adjusting for GA, no difference was noted in the incidence of ROP between the two groups. Multivariate analysis could not be performed for severe ROP due to inadequate sample size. CONCLUSION: Hyperglycemia in the initial 3 days of life is associated with an increased incidence of severe ROP in preterm infants. Neonatologists should aim to maintain euglycemia in these infants to decrease the risk of adverse outcomes. KEY POINTS: · Preterm infants have a high rate of both hypoglycemia and hyperglycemia.. · Majority of infants who were euglycemic or hypoglycemic at birth develop iatrogenic hyperglycemia.. · Hyperglycemia in the initial 3 days of life is associated with an increased incidence of severe ROP in preterm infants..
RESUMO
BACKGROUND: The aim of this study was to investigate the association between race and severe neonatal opioid withdrawal syndrome (NOWS) in infants exposed to intrauterine opioids. METHODS: This is a prospective observational study on intrauterine opioid-exposed term infants. Exposure to opioids was based on maternal disclosure, urine, or umbilical cord drug screening. Severe NOWS was defined based on modified Finnegan scoring and the need for pharmacological intervention. RESULTS: One hundred and fifty mother-infant pairs, 60 Black and 90 White with history of opioid exposure during pregnancy, were included. More White than Black infants developed NOWS that required pharmacological treatment, 70 vs. 40%: RR = 1.75 (1.25-2.45). In adjusted analysis, there was no significant association between race and the development of severe NOWS in mothers who attended opioid maintenance treatment program (OMTP). However, in mothers who did not attend OMTP, White race remained a significant factor associated with the development of severe NAS, RR = 1.69 (1.06, 2.69). CONCLUSIONS: Severe NOWS that required pharmacological intervention was significantly higher in White than in Black infants born to mothers who did not attend OMTP. Larger studies are needed to evaluate the association between social as well as genetic factors and the development of NOWS. IMPACT: There is a significant association between race and development of severe NOWS.

OBJECTIVE: To determine the effects of late surfactant on respiratory outcomes determined at 1-year corrected age in the Trial of Late Surfactant (TOLSURF), which randomized newborns of extremely low gestational age (≤28 weeks' gestational age) ventilated at 7-14 days to late surfactant and inhaled nitric oxide vs inhaled nitric oxide-alone (control). STUDY DESIGN: Caregivers were surveyed in a double-blinded manner at 3, 6, 9, and 12 months' corrected age to collect information on respiratory resource use (infant medication use, home support, and hospitalization). Infants were classified for composite outcomes of pulmonary morbidity (no PM, determined in infants with no reported respiratory resource use) and persistent PM (determined in infants with any resource use in ≥3 surveys). RESULTS: Infants (n = 450, late surfactant n = 217, control n = 233) were 25.3 ± 1.2 weeks' gestation and 713 ± 164 g at birth. In the late surfactant group, fewer infants received home respiratory support than in the control group (35.8% vs 52.9%, relative benefit [RB] 1.28 [95% CI 1.07-1.55]). There was no benefit of late surfactant for No PM vs PM (RB 1.27; 95% CI 0.89-1.81) or no persistent PM vs persistent PM (RB 1.01; 95% CI 0.87-1.17). After adjustment for imbalances in baseline characteristics, relative benefit of late surfactant treatment increased: RB 1.40 (95% CI 0.89-1.80) for no PM and RB 1.24 (95% CI 1.08-1.42) for no persistent PM. CONCLUSION: Treatment of newborns of extremely low gestational age with late surfactant in combination with inhaled nitric oxide decreased use of home respiratory support and may decrease persistent pulmonary morbidity.

Objective To study the characteristics of very low birth weight (VLBW) infants receiving glycerin suppositories (GS) and evaluate the association of GS use with outcomes. Study Design This is a retrospective study of VLBW infants admitted to a level III neonatal intensive care unit. Infants with birth weight between 500 and 1,499 g were evaluated. We evaluated the frequency of GS use and compared the characteristics and outcomes of the GS group with the no-GS group. Multivariate analyses controlling for gestational age and small for gestational age status were performed to study the effect of GS on outcomes. Results A total of 1,073 infants were included in the study. Out of those, 527 (49.1%) infants received GS. Incidence of necrotizing enterocolitis was not significantly different between the two groups, while days to reach full enteral feeds and length of hospital stay were significantly longer in the GS group. Conclusion Frequent use of GS warrants further prospective studies to evaluate its safety and efficacy in view of our study showing association with longer time to reach full enteral feeds. We speculate that GS use could be a marker for gastrointestinal dysmotility and hence the association with unfavorable clinical outcomes.

Objectives Trisomy 18 is presumed to be a lethal chromosomal abnormality; medical management of infants with this aneuploidy is controversial. Our objective was to describe our approach and experience with trisomy 18 infants. Study Design We reviewed the initial hospital course, management, and factors predicting discharge from the hospital from two large tertiary care neonatal intensive care units in the southern United States over 26 years. Results Of the 29 infants with trisomy 18, 21 (72%) died in the hospital and 8 (28%) were discharged home. 19 (66%) infants received mechanical ventilation and 10 (34%) received inotropic medications. Eight infants had critical congenital heart defects; only one survived to discharge. Three infants underwent major surgeries; one cardiac surgery, one tracheoesophageal fistula repair, and one myelomeningocele repair. Median length of hospital stay was 14 days (range, 0-78) for all the infants and 31 days (range, 18-66) for those that were discharged home. Factors associated with discharge from the hospital were female sex, higher gestational age, and absence of critical congenital heart defects. Median survival time was 13 days and was significantly longer for females compared with males. Our 1-month and 1-year survival rates were 31% and 3.9% respectively. Conclusion A significant proportion of infants with trisomy 18 were discharged home. These data are helpful in counseling parents of infants with trisomy 18.

Fluconazole is an effective agent for prophylaxis of invasive candidiasis in premature infants. The objective of this study was to characterize the population pharmacokinetics (PK) and dosing requirements of fluconazole in infants with birth weights of <750 g. As part of a randomized clinical trial, infants born at <750 g birth weight received intravenous (i.v.) or oral fluconazole at 6 mg/kg of body weight twice weekly. Fluconazole plasma concentrations from samples obtained by either scheduled or scavenged sampling were measured using a liquid chromatography-tandem mass spectrometry assay. Population PK analysis was conducted using NONMEM 7.2. Population PK parameters were allometrically scaled by body weight. Covariates were evaluated by univariable screening followed by multivariable assessment. Fluconazole exposures were simulated in premature infants using the final PK model. A population PK model was developed from 141 infants using 604 plasma samples. Plasma fluconazole PK were best described by a one-compartment model with first-order elimination. Only serum creatinine was an independent predictor for clearance in the final model. The typical population parameter estimate for oral bioavailability in the final model was 99.5%. Scavenged samples did not bias the parameter estimates and were as informative as scheduled samples. Simulations indicated that the study dose maintained fluconazole troughs of >2,000 ng/ml in 80% of simulated infants at week 1 and 59% at week 4 of treatment. Developmental changes in fluconazole clearance are best predicted by serum creatinine in this population. A twice-weekly dose of 6 mg/kg achieves appropriate levels for prevention of invasive candidiasis in extremely premature infants.

OBJECTIVE: To compare the effect of initiating human milk fortification at 2 different feeding volumes on feeding intolerance and the time to reach full feeding volume. STUDY DESIGN: Very low birth weight infants (n = 100) were prospectively randomized to early fortification (EF) (beginning at a feeding volume of 20 mL/kg/d) or delayed fortification (at a feeding volume of 100 mL/kg/d). We employed a standardized feeding protocol and parenteral nutrition guidelines for the nutritional management of all study infants. RESULTS: The median days to reach full feeding volumes were equivalent in the 2 groups (20 vs 20, P = .45). No significant difference was observed in the total number of episodes of feeding intolerance (58 vs 57). Two cases of necrotizing enterocolitis (Bell stage ≥2) and deaths occurred in each group. Median daily protein intake (g/kg/d) was higher in EF group in week 1 (3.3 [3.2, 3.5] vs 3.1 [2.9, 3.3], P < .001), week 2 (3.6 [3.5, 3.8] vs 3.2 [2.9, 3.4], P < .001), and week 3 (3.7 [3.4, 3.9] vs 3.5 [2.8, 3.8], P = .006). Cumulative protein intake (g/kg) in the first 4 weeks of life was higher in EF group (98.6 [93.8, 104] vs 89.6 [84.2, 96.4], P < .001). CONCLUSIONS: Very early human milk fortification may improve early protein intake in very low birth weight infants without increasing frequencies of adverse events. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01988792.

OBJECTIVE: To assess whether late surfactant treatment in extremely low gestational age (GA) newborn infants requiring ventilation at 7-14 days, who often have surfactant deficiency and dysfunction, safely improves survival without bronchopulmonary dysplasia (BPD). STUDY DESIGN: Extremely low GA newborn infants (GA ≤28 0/7 weeks) who required mechanical ventilation at 7-14 days were enrolled in a randomized, masked controlled trial at 25 US centers. All infants received inhaled nitric oxide and either surfactant (calfactant/Infasurf) or sham instillation every 1-3 days to a maximum of 5 doses while intubated. The primary outcome was survival at 36 weeks postmenstrual age (PMA) without BPD, as evaluated by physiological oxygen/flow reduction. RESULTS: A total of 511 infants were enrolled between January 2010 and September 2013. There were no differences between the treated and control groups in mean birth weight (701 ± 164 g), GA (25.2 ± 1.2 weeks), percentage born at GA <26 weeks (70.6%), race, sex, severity of lung disease at enrollment, or comorbidities of prematurity. Survival without BPD did not differ between the treated and control groups at 36 weeks PMA (31.3% vs 31.7%; relative benefit, 0.98; 95% CI, 0.75-1.28; P = .89) or 40 weeks PMA (58.7% vs 54.1%; relative benefit, 1.08; 95% CI, 0.92-1.27; P = .33). There were no between-group differences in serious adverse events, comorbidities of prematurity, or severity of lung disease to 36 weeks. CONCLUSION: Late treatment with up to 5 doses of surfactant in ventilated premature infants receiving inhaled nitric oxide was well tolerated, but did not improve survival without BPD at 36 or 40 weeks. Pulmonary and neurodevelopmental assessments are ongoing. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01022580.

OBJECTIVE: This study aims to study the association between trends in medication utilization and survival in very low-birth-weight (VLBW) infants over a 22-year period. STUDY DESIGN: Medications received by VLBW infants were extracted retrospectively for the four periods 1990 to 1994, 1995 to 2000, 2001 to 2005, and 2006 to 2011 from our perinatal database and stratified by two birth weight groups: ≤ 1,000 g and 1,001 to 1,500 g. RESULT: A total of 5,529 VLBW infants were reviewed. The majority of them were African American (78%), with an increasing proportion over time. The median number of medications per patient in all VLBW infants remained similar over time, 9 (5, 15). A cardiovascular group of medications was most commonly used, with a significant increase in the use of dobutamine and indomethacin. A significant trend toward an increasing number of infants without any antibiotic exposure was also noted. Survival steadily and significantly increased from 83 to 87%. CONCLUSION: The trends of overall medication use remained the same in our neonatal intensive care unit (NICU) over the past 22 years. There was no association between medication utilization and survival. VLBW infants continue to receive a high number of medications in the NICU, including a variety of antibiotics.

OBJECTIVE: This study aims to evaluate whether infants born at ≤ 32 weeks' gestational age (GA) can mount C-reactive protein (CRP) responses during early onset bacterial sepsis that are comparable to infants born at > 32 weeks' GA. METHODS: Retrospectively (2003-2012) infants with a positive bacterial culture during the first 72 hours of life were identified and grouped into two categories based on their GA: ≤ 32 weeks (group A) and > 32 weeks (group B). RESULTS: Group A included 25 and group B included 122 infants. Both groups responded similarly to sepsis with an increase in CRP (p = 0.59). Each group had a significant change in intragroup CRP levels over time (p < 0.0001). However, in both groups, the degree of this change was at the same rate over time (p = 0.74). CONCLUSION: CRP responses to bacterial sepsis during the first 72 hours of life in infants born at ≤ 32 weeks' GA are comparable to infants born at > 32 weeks' GA.

BACKGROUND: Invasive methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-sensitive Staphylococcus aureus (MSSA) infections are major causes of numerous neonatal intensive care unit (NICU) outbreaks. There have been increasing reports of MRSA outbreaks in various neonatal intensive care units (NICUs) over the last decade. Our objective was to review the experience of Staphylococcus aureus sepsis in our NICU in the last decade and describe the trends in the incidence of Staphylococcus aureus blood stream infections from 2000 to 2009. METHODS: A retrospective perinatal database review of all neonates admitted to our NICU with blood cultures positive for Staphylococcus aureus from (Jan 1st 2000 to December 31st 2009) was conducted. Infants were identified from the database and data were collected regarding their clinical characteristics and co-morbidities, including shock with sepsis and mortality. Period A represents patients admitted in 2000-2003. Period B represents patients seen in 2004-2009. RESULTS: During the study period, 156/11111 infants were identified with Staphylococcus aureus blood stream infection: 41/4486 (0.91%) infants in Period A and 115/6625 (1.73%) in Period B (p < 0.0004). Mean gestation at birth was 26 weeks for infants in both periods. There were more MRSA infections in Period B (24% vs. 55% p < 0.05) and they were associated with more severe outcomes. In comparing the cases of MRSA infections observed in the two periods, infants in period B notably had significantly more pneumonia cases (2.4% vs. 27%, p = 0.0005) and a significantly higher mortality rate (0% vs. 15.7%, p = 0.0038). The incidences of skin and soft tissue infections and of necrotizing enterocolitis were not significantly changed in the two periods. CONCLUSION: There was an increase in the incidence of Staphylococcus aureus infection among neonates after 2004. Although MSSA continues to be a problem in the NICU, MRSA infections were more prevalent in the past 6 years in our NICU. Increased severity of staphylococcal infections and associated rising mortality are possibly related to the increasing MRSA infections with a more virulent community-associated strain.

OBJECTIVE: Our aim was to refine the essential newborn care practices by employing the multidisciplinary peer team-led quality improvement (QI) projects. DESIGN: In 2017, concerning the same, the department focused on early initiation of breast feeding, prevention of hypothermia within an hour of life and rational usage of antibiotics among babies admitted to neonatal intensive care unit (NICU). Baseline data reported the rate of initiation of breast feeding, hypothermia and antibiotic exposure rate as 35%, 78% and 75%, respectively. Root causes were analysed and a series of Plan-Do-Study-Act cycles were conducted to test the changes. The process of change was studied through run charts (whereas control charts were used for study purpose). RESULT: After the implementation of the QI projects, the rate of initiation of breast feeding was found to be improved from 35% to 90%, the incidence of hypothermia got reduced from 78% to 10% and the antibiotic exposure rate declined from 75% to 20%. Along with the improvement in indicators related to essential newborn care, down the stream we found a decrease in the percentage of culture-positive sepsis rate in the NICU. CONCLUSION: Peer team-led QI initiatives in a resource-limited setting proved beneficial in improving essential newborn care practices.

The objective of this study is to evaluate the effectiveness of a cue-based feeding protocol in improving time to nipple feed and time to discharge in very low birth weight infants in a Level III Neonatal Intensive Care Unit. Demographic, feeding, and discharge data were recorded and compared between the two cohorts. The pre-protocol cohort included infants born from August 2013 through April 2016 and the post-protocol cohort included infants born from January 2017 through December 2019. 272 infants were included in the pre-protocol cohort and 314 infants in the post-protocol cohort. Both cohorts were statistically comparable in gestational age, gender, race, birthweight, prenatal care, antenatal steroid use, and rates of maternal diabetes. There were statistically significant differences between the pre- versus post-protocol cohorts in median post-menstrual age (PMA) in days at first nipple feed (PO) (240 vs 238, p = 0.025), PMA in days at full PO (250 vs 247, p = 0.015), and length of stay in days (55 vs 48, p = 0.0113). Comparing each year in the post-protocol cohort, for each outcome measure, a similar trend was noted in 2017 and 2018, but not in 2019. In conclusion, the cue-based feeding protocol was associated with a decrease in the time to first PO, time to full nipple feeds, and the length of stay in very-low-birthweight infants.

Bronchopulmonary Dysplasia (BPD) is a multifactorial disease affecting over 35% of extremely preterm infants born each year. Despite the advances made in understanding the pathogenesis of this disease over the last five decades, BPD remains one of the major causes of morbidity and mortality in this population, and the incidence of the disease increases with decreasing gestational age. As inflammation is one of the key drivers in the pathogenesis, it has been targeted by majority of pharmacological and non-pharmacological methods to prevent BPD. Most extremely premature infants receive a myriad of medications during their stay in the neonatal intensive care unit in an effort to prevent or manage BPD, with corticosteroids, caffeine, and diuretics being the most commonly used medications. However, there is no consensus regarding their use and benefits in this population. This review summarizes the available literature regarding these medications and aims to provide neonatologists and neonatal providers with evidence-based recommendations.
RESUMO
BACKGROUND: We report a statewide quality improvement initiative aimed to decrease the incidence of extrauterine growth restriction among very low birth weight infants cared for in Tennessee NICUs. METHODS: The cohort consisted of infants born appropriate for gestational age between May 2016 and December 2018 from 9 NICUs across Tennessee. The infants were 23 to 32 weeks gestation and 500 to 1499 g birth weight. The process measures were the hours of life (HOL) when parenteral protein and intravenous lipid emulsion were initiated, the number of days to first enteral feeding, and attainment of full enteral caloric intake (110-130 kcal/kg per day). The primary outcome was extrauterine growth restriction, defined as weight <10th percentile for weight at 36 weeks postmenstrual age. Statistical process control charts and the Shewhart control rules were used to find special cause variation. RESULTS: Although special cause variation was not indicated in the primary outcome measure, it was indicated for the reduction in specific process measures: HOL when parenteral protein was initiated, HOL when intravenous lipid emulsion was initiated, and the number of days to attainment of full enteral caloric intake (among the hospitals considered regional perinatal centers). CONCLUSIONS: A statewide quality improvement initiative led to earlier initiation of parenteral and enteral nutrition and improved awareness of the importance of postnatal nutrition.

Bronchopulmonary dysplasia (BPD) continues to be a major pulmonary complication in very low birth weight (VLBW) and extremely low birth weight (ELBW) survivors of neonatal intensive care units (NICUs). Many factors including partial pressures of carbon dioxide (PaCO: (2)) have been implicated as possible causes. Permissive hypercapnia has become a more common practice in ventilated infants, but its effect on BPD is unclear. The hypothesis of this study was that hypercarbia is associated with increased BPD in infants with birth weights of 500-1,499 g. Nine hospitals were involved in this observational cohort study. Maternal and infant information including socio-demographics, antenatal steroids, gender, race, gestational age, birth weight, intubation and ventilator status, physiologic variables and data on therapies were collected by chart abstraction. SNAP scores were assigned. Candidate BPD risk factors, including cumulative exposures derived from blood gas and ventilation data in the first 6 days of life, were identified. Risk models were developed for 425 preterm infants who survived to 36 weeks post-menstrual age. BPD occurrence was associated with the cumulative burden of MAP >0 cm H(2)O in the first 6 days of life (P < 0.0001). After adjustment for the burden of MAP, the occurrence of hypercarbia (PaCO: (2) >50 torr) was associated with a greater incidence of BPD (P = 0.024). Among 293 intubated, mechanically ventilated infants, those with hypercarbia occurring only when MAP ≤ 8 cm H(2)O, a scenario more comparable to permissive hypercapnia, also had increased BPD incidence compared to infants without hypercarbia (P = 0.0003). Hypercarbia during the first 6 days of life was associated with increased incidence of BPD in these infants. Mechanically ventilated infants with hypercarbia during low MAP also had a significant increase in BPD. Permissive hypercapnia in ventilated infants needs further close review before the practice becomes even more widespread.

BACKGROUND: Glycohemoglobins (GHb) are the products of irreversible non-enzymatic reactions between glucose and the hemoglobin molecule. Glycosylation of proteins in general can modify protein structure and alter catalytic properties, thereby causing cellular dysfunction. The aim of the present study was to test the hypothesis that protein glycosylation levels in premature infants are elevated compared with full-term infants (neonates). Blood GHb levels in pre-term and full-term infants were studied, and the in vitro glycosylation of erythrocytes obtained from both pre-term and full-term infants was assessed. METHODS: Cord-blood from 31 pre-term and 11 full-term infants was collected and GHb levels were determined using affinity columns. Erythrocytes from the cord blood of 17 additional infants (eight pre-term, ≤ 36 weeks gestation, and nine full-term, ≥ 37 weeks gestation) were obtained and incubated for 24 h in a high-glucose medium. Baseline and post-incubation GHb levels were calculated to determine the in vitro susceptibility of pre-term versus full-term infants to glycosylation. RESULTS: Blood GHb levels were significantly higher (P < 0.01) in full-term compared with pre-term infants. The percent increase in GHb formation in vitro was similar between the erythrocytes of full-term and those of pre-term infants. CONCLUSION: Contrary to the original hypothesis, the erythrocytes of pre-term infants do not show increased glycosylation of proteins when compared with those of full-term infants.

Antibiotic misuse is the most common cause of antimicrobial resistance-a globally declared emergency. This necessitates the introduction of rational antibiotic usage management policy. The paediatrics department of a public teaching hospital with around 500 neonatal intensive care unit (NICU) admissions annually revealed 75% of NICU admission exposure to any antibiotics. The aim was to institute antibiotic stewardship programme (ASP) to optimise antibiotic usage from existing 75% to 40% in a 6-month period through a quality improvement (QI) project.A root cause analysis using fishbone diagram was performed to identify the possible reasons for the high antibiotic usage. Six Plan-Do-Study-Act cycles were conducted to implement the protocols for usage of antibiotics for well-defined indications; active laboratory engagement to decrease the turnaround time for blood culture results; a hard stop to all antibiotic orders after 72 hours; streamlining of antibiotic usage; strengthening universal aseptic practices; and confidence building of staff. The outcomes monitored were antibiotic exposure rates, average number of antibiotic days in all NICU admissions, sepsis rates and mortality.Institution of ASP had significantly reduced antibiotic exposure in NICU admissions, that is, from 75% in March to 41% in August 2018. Median (IQR) antibiotic days per infant in NICU went down from 3 to 0 (0-6). The per cent of NICU admission with culture-positive sepsis and all-cause mortality rate in NICU declined from 18% to 11.56% and 25% to 16%, respectively, over these 6 months.Thus, ASP for rationalising antibiotic usage was successfully instituted in NICU of a rural medical college in central India through QI, without any adverse effect on sepsis and mortality.

BACKGROUND: To describe amplitude-integrated encephalogram (aEEG) characteristics of neonates with neonatal abstinence syndrome (NAS). METHODS: This is a prospective observational study. Newborns exposed to prenatal opioids and their gestational matched controls were included. A single-channel aEEG was obtained using Olympic 6000 CFM monitor. The background activity (continuous/discontinuous), the amplitudes (µV) and the presence of sleep-wake cycle (SWC) were documented. RESULTS: A total of 59 infants, 23 with NAS and 36 controls were enrolled. All aEEG were completed within 48 hours of life prior to initiation of treatment. Birth weight and gestational age were similar in both groups. An aEEG was abnormal (discontinuous pattern and/or absent SWC) in 78 % (18/23) of infants with NAS versus only 25% in control group (9/36), [OR 10.8, CI (2.7-46.5) Pâ<â0.001]. 61% of infants with NAS had discontinuous pattern [OR 7.8, CI (2-32) Pâ=â0.001] and 39% had absence of sleep-wake cycle [OR 7.1, CI (1.4-39.4) Pâ=â0.007]. CONCLUSIONS: A majority of infants with NAS have abnormal aEEG activity.

Objective. The objective of this study was to determine factors contributing to improvements in infant mortality rates (IMR) and composite morbidity-mortality in very-low-birth-weight (VLBW) infants after initiating a new perinatal program in 2009 at Regional One Health (ROH). VLBW infants account for 67% of infant deaths. Design. This is a pre-/postintervention cohort study of prospectively gathered data. Population. VLBW infants delivered at ROH during the 2004 to 2015 study period. Setting. ROH is a Regional Perinatal Center affiliated with the University of Tennessee Health Science Center. Methods. We studied 2364 consecutive VLBW infants. Multivariate models were applied to determine factors contributing significantly to the reduction in the outcome measures as well as trends over time. Main Outcome Measures. Primary outcomes were IMR and composite morbidity-mortality rates. Standardized, risk-adjusted mortality and composite morbidity ratios were also reported as defined by the Vermont Oxford Network. Results. Mortality declined from 15.5% in Pre-Implementation to 13.1% in Post-Implementation (P = .093), corresponding to an 18% reduction in odds. The combined factors of composite morbidity-mortality rate decreased from 55.7% in Pre-Implementation to 43.9% in Post-Implementation (P < .0001), representing a 38% reduction in odds. Standardized, risk-adjusted mortality and composite morbidity ratios improved during the study period from 20% above to 20% below the expected rate. Increases in the administration of antenatal steroids, surfactant administration, cesarean delivery, and perhaps other programmatic changes that were observational and unaccounted in the model were associated with improvements in outcome measures. Conclusions. Decreased mortality and composite morbidity-mortality in VLBW infants delivered at ROH were found following the initiation of a new perinatal program.
