Abstract
Background Effect of duration of birth depression on neurodevelopmental outcomes in low- and middle-income countries (LMICs) is not known. We examined the association of birth depression with brain injury, neurodevelopmental outcomes, and hypothermia after hypoxic ischemic encephalopathy (HIE) in south Asia. Methods We compared cerebral magnetic resonance (MR) at 2 weeks, and adverse outcomes (death or moderate or severe disability) at 18 months in 408 babies with moderate or severe HIE who had long birth depression (positive pressure ventilation (PPV) >10 min or Apgar score<6 at 10 min or cord pH < 7.0) and short birth depression (PPV for 5-10 min or Apgar score<6 at 5 min, but ≥6 at 10 min). Findings Long depression group (n = 201) had more severe HIE (32.8% versus 6.8%), mortality (47.5% versus 26.4%), death or disability at 18 months (62.2% versus 35.4%) (all p < 0.001), MR injury (Odds ratio; 95% CI) to basal ganglia (2.4 (1.3, 4.1); p = 0.003), posterior limb of internal capsule (2.3 (1.3, 4.3); p < 0.001) and white matter (1.7 (1.1, 2.7); p = 0.021), and lower thalamic N-acetylaspartate levels (7.69 ± 1.84 versus 8.29 ± 1.60); p = 0.031) than short depression group (n = 207). Three babies had no heartbeat at 5 min, of which 1 died and 2 survived with severe disability. No significant interaction between the duration of birth depression and whole-body hypothermia was seen for any of the MR biomarker or clinical outcomes. Interpretation Long birth depression was associated with more brain injury and adverse outcomes than short depression. Effect of hypothermia was not modified by duration of birth depression.

Abstract
Importance The association between place of birth and hypothermic neuroprotection after hypoxic-ischemic encephalopathy (HIE) in low- and middle-income countries (LMICs) is unknown. Objective To ascertain the association between place of birth and the efficacy of whole-body hypothermia for protection against brain injury measured by magnetic resonance (MR) biomarkers among neonates born at a tertiary care center (inborn) or other facilities (outborn). Design, Setting, and Participants This nested cohort study within a randomized clinical trial involved neonates at 7 tertiary neonatal intensive care units in India, Sri Lanka, and Bangladesh between August 15, 2015, and February 15, 2019. A total of 408 neonates born at or after 36 weeks' gestation with moderate or severe HIE were randomized to receive whole-body hypothermia (reduction of rectal temperatures to between 33.0 °C and 34.0 °C; hypothermia group) for 72 hours or no whole-body hypothermia (rectal temperatures maintained between 36.0 °C and 37.0 °C; control group) within 6 hours of birth, with follow-up until September 27, 2020. Exposure 3T MR imaging, MR spectroscopy, and diffusion tensor imaging. Main Outcomes and Measures Thalamic N-acetyl aspartate (NAA) mmol/kg wet weight, thalamic lactate to NAA peak area ratios, brain injury scores, and white matter fractional anisotropy at 1 to 2 weeks and death or moderate or severe disability at 18 to 22 months. Results Among 408 neonates, the mean (SD) gestational age was 38.7 (1.3) weeks; 267 (65.4%) were male. A total of 123 neonates were inborn and 285 were outborn. Inborn neonates were smaller (mean [SD], 2.8 [0.5] kg vs 2.9 [0.4] kg; P = .02), more likely to have instrumental or cesarean deliveries (43.1% vs 24.7%; P = .01), and more likely to be intubated at birth (78.9% vs 29.1%; P = .001) than outborn neonates, although the rate of severe HIE was not different (23.6% vs 17.9%; P = .22). Magnetic resonance data from 267 neonates (80 inborn and 187 outborn) were analyzed. In the hypothermia vs control groups, the mean (SD) thalamic NAA levels were 8.04 (1.98) vs 8.31 (1.13) among inborn neonates (odds ratio [OR], -0.28; 95% CI, -1.62 to 1.07; P = .68) and 8.03 (1.89) vs 7.99 (1.72) among outborn neonates (OR, 0.05; 95% CI, -0.62 to 0.71; P = .89); the median (IQR) thalamic lactate to NAA peak area ratios were 0.13 (0.10-0.20) vs 0.12 (0.09-0.18) among inborn neonates (OR, 1.02; 95% CI, 0.96-1.08; P = .59) and 0.14 (0.11-0.20) vs 0.14 (0.10-0.17) among outborn neonates (OR, 1.03; 95% CI, 0.98-1.09; P = .18). There was no difference in brain injury scores or white matter fractional anisotropy between the hypothermia and control groups among inborn or outborn neonates. Whole-body hypothermia was not associated with reductions in death or disability, either among 123 inborn neonates (hypothermia vs control group: 34 neonates [58.6%] vs 34 [56.7%]; risk ratio, 1.03; 95% CI, 0.76-1.41), or 285 outborn neonates (hypothermia vs control group: 64 neonates [46.7%] vs 60 [43.2%]; risk ratio, 1.08; 95% CI, 0.83-1.41). Conclusions and Relevance In this nested cohort study, whole-body hypothermia was not associated with reductions in brain injury after HIE among neonates in South Asia, irrespective of place of birth. These findings do not support the use of whole-body hypothermia for HIE among neonates in LMICs. Trial Registration ClinicalTrials.gov Identifier: NCT02387385.

Abstract
BACKGROUND Although therapeutic hypothermia reduces death or disability after neonatal encephalopathy in high-income countries, its safety and efficacy in low-income and middle-income countries is unclear. We aimed to examine whether therapeutic hypothermia alongside optimal supportive intensive care reduces death or moderate or severe disability after neonatal encephalopathy in south Asia. METHODS We did a multicountry open-label, randomised controlled trial in seven tertiary neonatal intensive care units in India, Sri Lanka, and Bangladesh. We enrolled infants born at or after 36 weeks of gestation with moderate or severe neonatal encephalopathy and a need for continued resuscitation at 5 min of age or an Apgar score of less than 6 at 5 min of age (for babies born in a hospital), or both, or an absence of crying by 5 min of age (for babies born at home). Using a web-based randomisation system, we allocated infants into a group receiving whole body hypothermia (33·5°C) for 72 h using a servo-controlled cooling device, or to usual care (control group), within 6 h of birth. All recruiting sites had facilities for invasive ventilation, cardiovascular support, and access to 3 Tesla MRI scanners and spectroscopy. Masking of the intervention was not possible, but those involved in the magnetic resonance biomarker analysis and neurodevelopmental outcome assessments were masked to the allocation. The primary outcome was a combined endpoint of death or moderate or severe disability at 18-22 months, assessed by the Bayley Scales of Infant and Toddler Development (third edition) and a detailed neurological examination. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, NCT02387385. FINDINGS We screened 2296 infants between Aug 15, 2015, and Feb 15, 2019, of whom 576 infants were eligible for inclusion. After exclusions, we recruited 408 eligible infants and we assigned 202 to the hypothermia group and 206 to the control group. Primary outcome data were available for 195 (97%) of the 202 infants in the hypothermia group and 199 (97%) of the 206 control group infants. 98 (50%) infants in the hypothermia group and 94 (47%) infants in the control group died or had a moderate or severe disability (risk ratio 1·06; 95% CI 0·87-1·30; p=0·55). 84 infants (42%) in the hypothermia group and 63 (31%; p=0·022) infants in the control group died, of whom 72 (36%) and 49 (24%; p=0·0087) died during neonatal hospitalisation. Five serious adverse events were reported: three in the hypothermia group (one hospital readmission relating to pneumonia, one septic arthritis, and one suspected venous thrombosis), and two in the control group (one related to desaturations during MRI and other because of endotracheal tube displacement during transport for MRI). No adverse events were considered causally related to the study intervention. INTERPRETATION Therapeutic hypothermia did not reduce the combined outcome of death or disability at 18 months after neonatal encephalopathy in low-income and middle-income countries, but significantly increased death alone. Therapeutic hypothermia should not be offered as treatment for neonatal encephalopathy in low-income and middle-income countries, even when tertiary neonatal intensive care facilities are available.

Abstract
Clinical risk index for babies II (CRIB II) score is simple, validated and widely used risk-adjustment instrument for predicting mortality among preterm low birth weight babies. To assess the efficacy of CRIB II score as a tool to predict the risk for neonatal death among the preterm and LBW babies admitted in NICU of BSMMU, a tertiary care hospital in Bangladesh. This prospective observational study was conducted in Department of Neonatology in BSMMU from September 2016 to August 2017. Inborn preterm neonates with gestational age ≤34 weeks admitted were enrolled in the study. CRIB-II score was calculated for each infant within 1 hour of birth from birth weight, gestational age, sex, admission temperature and base excess. The primary outcome measured in the study was neonatal death or survival up to 28 days. Total 112 patients were finally analyzed in this study. Mean CRIB II score was significantly higher in the non-survivor group compared to the survivor group (p-value <0.0001). Receiver operating characteristic (ROC) curve analysis for mortality prediction by CRIB II score, gestational age and birth weight showed AUC 0.87 (95% CI 0.76-0.97), 0.76 (95% CI 0.63-0.88) and 0.79 (95% CI 0.66-0.92) respectively. ROC curve analysis also revealed that the most suitable cut-off points for predicting mortality were 5 for CRIB II score, 32 weeks for gestational age and 1250 gram for birth weight. Using these most suitable cut-off points, CRIB II score had the highest sensitivity and specificity followed by birth weight and gestational age. In this study, CRIB II score was found to be an effective tool for predicting neonatal death among preterm LBW babies. It predicted outcome more accurately than birth weight or gestational age alone.

Abstract
Bartter syndrome is an autosomal recessive disorder manifested by a defect in sodium-potassium-chloride transport in the thick ascending limb of Henle with different genetic origins and molecular pathophysiology. Bartter syndrome usually a common disease in children and in early infancy presented with persistent polyuria and associated with dehydration, electrolyte imbalance, and failure to thrive. Though prompt diagnosis and proper treatment of Bartter syndrome may improve the outcome, some children will progress to renal failure. We report a case of a 6 days-old male infant who was admitted in Neonatal Intensive Care Unit, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh on 26 April 2018 for prematurity and low birth weight. On subsequent follow up he developed electrolyte imbalance and failure to thrive. Laboratory studies revealed hyponatremia, hypochloremic metabolic alkalosis with severe hypokalemia. When excessive chloride losses appear to be renal in origin and the patient has normal blood pressure and high levels of serum renin and aldosterone were considered as Bartter syndrome. Molecular genetic studies are indicated to identify the primary genetic defect.

Abstract
Neonatal sepsis, a major newborn killer worldwide exhibits wide spectrum of clinical manifestations. Epidemiology and aetiological organisms vary with geographical area and time. Objective of the study was to study clinical characteristics, epidemiology, bacterial aetiology and drug sensitivity pattern of isolated organisms in Neonatal Intensive Care Unit (NICU), Dhaka Medical College Hospital (DMCH), Dhaka, Bangladesh. This observational cross sectional study was carried out in NICU, DMCH from January 2014 to June 2015. The inclusion criteria were newborns having features of sepsis at admission or developing such features afterwards when admitted for other indications. A blood sample was collected aseptically immediately after clinical diagnosis and was sent for relevant laboratory investigations. Sample for culture sensitivity was inoculated bedside to culture bottle and sent to department of microbiology. The newborns were followed up till hospital discharge or death. All information regarding history, laboratory findings and follow up were recorded in a structured questionnaire. Of the 200 neonates, 59% were diagnosed as having late onset sepsis (LONS). Premature and low birth weight (LBW) babies mostly suffered from LONS. Respiratory distress, tachycardia, lethargy were the predominant symptoms in both early and late sepsis. Blood culture yielded growth in 55% of the septic newborns. Klebsiella pneumoniae was the predominant organism in both early and late sepsis. Most of the Gram negative bacteria were sensitive to colistin, meropenem and imipenem. Case fatality was 24.39% and 34.74% in early and late sepsis respectively.

Abstract
Neonatal sepsis (NS) is a life-threatening disorder and an important cause of morbidity and mortality in neonates. Blood culture, the gold standard for diagnosis of neonatal sepsis is costly, not available at all centres and test result not readily available. CRP is low cost diagnostic test for neonatal sepsis which is possible to perform at all centres and test result is easily available. We aimed to evaluate the usefulness of C-reactive protein (CRP) measurement to identify neonatal sepsis. We conducted this meta-analysis to investigate the diagnostic accuracy of the CRP in neonatal sepsis. The literature was searched in PUBMED, Cochrane Library, Google scholar and other Medical Databases using set search criteria. Each included study was evaluated by quality assessment of diagnostic accuracy studies (QUADAS) tool. Four investigators independently extracted the data and study characteristics, and disagreements, if any, were resolved by consensus. Meta-disc software was used to calculate the pooled sensitivity, specificity and summary diagnostic odds ratio (SDOR), I² or Cochrane Q to test heterogeneity. False positive report probability (FPRP) was calculated to confirm the significance of the results. Eleven studies (1557 neonates) were included in this meta-analysis. The pooled sensitivity and specificity of CRP were 71% and 86% respectively, which had moderate accuracy in the diagnosis of NS. The pooled diagnostic odds ratio (DOR) and area under curve (AUC) was 19.10 and 0.8535 (Q*=0.7845), respectively. The diagnostic threshold analysis showed that there was no threshold effect. Meta-analysis showed that CRP had a moderate accuracy (AUC=0.8535) for the diagnosis of NS. CRP is a helpful biomarker for diagnosis of NS. However, we should combine the results with clinical symptoms and signs, laboratory and microbial results.

Abstract
Safe transportation is mostly an unnoticed neonatal health issue in Bangladesh and no documentation is available regarding the existing practices. So this study was intended to document transport status of the referred newborn to a tertiary care hospital. This observational study included 150 out born neonates over 12 months period transported from various places to NICU, Bangabandhu Sheikh Mujib Medical University (BSMMU) from May 2015 to April 2016. A structured data collection form was used to record information categorized into pre-transport, during transport and at admission. At admission detailed clinical assessment of the baby was done and recorded. Outcome was determined as discharge or death. Of 150 transported neonates, two-third were preterm 115(77%) & LBW 113(75%). Common indications for referral were prematurity and sepsis. Most of the patients were referred from private hospital 107(71%). Majority of newborns (86%) were referred from hospitals of Dhaka city while only 14% were referred from outside Dhaka. Referral notes were supplied in most of the cases 134(89%) but comprehensive information was obtainable only in 3 cases. Although main transport vehicle was ambulance 130(87%), medical personnel accompanied the sick baby only in 6(4%) of cases. The distance traveled was less than 10 kilometers (kms) in 95(63%) and more than 100 km in 10(7%) of enrolled neonates. Transport time was less than 1 hour in 72(48%), 1-6 hours in 66(44%) and more than 6 hours in 12(8%) of cases. Nearly two third of newborn were transported after office period, 107(72%). At admission 21(14%) babies had hypothermia, 8(7.62%) hypoglycemia, 16(11%), poor perfusion 28(19%), low saturation 27(18%). Hyperthermia & hyperglycemia were observed in 8(5%) & 7(5%) cases respectively. Of the total 150 babies referred, 17(11%) died. While comparing with discharged newborn, died newborn were more frequent sufferer of hypothermia (p value 0.007) and low saturation (p value 0.049) at admission. Premature, low birth weight and sick newborns are being transported despite lack of safe transport system.
