Abstract
OBJECTIVE Survival of preterm infants differs dramatically depending on birthplace. No previous studies have compared outcomes of preterm infants between low middle-income and high-income countries such as India and the United States. The purpose of this study is to evaluate differences in care practices, resources, mortality, and morbidities in preterm infants with birth weight 700 to 1,500 g between two major neonatal centers in these countries. STUDY DESIGN This is a retrospective cohort study with de-identified data from Fernandez Hospital (FH) in Hyderabad, India, and Texas Children's Hospital (TCH) in Houston, TX, for infants born January 2016 to December 2018, and weighing 700 to 1,500 g at birth. The primary outcome was death before hospital discharge. RESULTS Of 1,195 infants, 736 were admitted to FH and 459 were admitted to TCH. After controlling for differences in gestational age, small for gestational age, and antenatal corticosteroid use, TCH patients had lower mortality before hospital discharge (adjusted odds ratio [aOR] = 0.28, 95% confidence interval [CI]: 0.16-0.48, p < 0.001) and more bronchopulmonary dysplasia (BPD; aOR = 2.2, 95% CI: 1.51-3.21, p < 0.001). The composite outcome of death or BPD and death or any major morbidity (BPD or intraventricular hemorrhage grade II or more or periventricular leukomalacia grade II or more or retinopathy of prematurity requiring treatment) were not different. CONCLUSION In this study, TCH infants had decreased odds of death before hospital discharge compared with FH but higher odds of BPD, which may be related to increased survival and differences in care practices. KEY POINTS · Few studies compared outcomes of premature infants between different high-income countries.. · There are no studies comparing preterm infants between low middle-income and high-income countries such as India and the United States.. · This study evaluated detailed comparison of care practices and infrastructure of NICUs in India and United states..

Abstract
The aim of our study was to evaluate the impact of the T-piece resuscitator in the delivery room management of pre-term neonates in a resource-limited setting. We compared the incidence rates of delivery room intubation, surfactant replacement therapy, pulmonary air leak syndrome, and pre-term very low birth weight infant mortality, before and after T-piece use. Bi-monthly neonatal resuscitation training sessions were conducted for healthcare providers during the study period. We emphasized hands-on experience with the T-piece resuscitator and delivery room early respiratory care practices during the post-intervention epoch. Our pre- and post-intervention data recorded statistically significant decline in delivery room intubations, a 32% decrease in surfactant replacement therapy, and a 57% decrease in air leaks in pre-term neonates. However, the use of T-piece resuscitator did not have a statistically significant effect on pre-term very low birth weight infant mortality.

Abstract
Pulmonary surfactant is a complex lipoprotein mixture secreted into the alveolar lumen by type 2 pneumocytes, which is composed by tens of different lipids (approximately 90% of its entire mass) and surfactant proteins (approximately 10% of the mass). It is crucially involved in maintaining lung homeostasis by reducing the values of alveolar liquid surface tension close to zero at end-expiration, thereby avoiding the alveolar collapse, and assembling a chemical and physical barrier against inhaled pathogens. A deficient amount of surfactant or its functional inactivation is directly linked to a wide range of lung pathologies, including the neonatal respiratory distress syndrome. This paper reviews the main biophysical concepts of surfactant activity and its inactivation mechanisms, and describes the past, present and future roles of surfactant replacement therapy, focusing on the exogenous surfactant preparations marketed worldwide and new formulations under development. The closing section describes the pulmonary surfactant in the context of drug delivery. Thanks to its peculiar composition, biocompatibility, and alveolar spreading capability, the surfactant may work not only as a shuttle to the branched anatomy of the lung for other drugs but also as a modulator for their release, opening to innovative therapeutic avenues for the treatment of several respiratory diseases.

Evidence-based interventions to reduce mortality among preterm and low-birthweight neonates in low-income and middle-income countries: a systematic review and meta-analysis. BMJ Glob Health 2021; 6:bmjgh-2020-003618. [PMID: 33602687 PMCID: PMC7896575 DOI: 10.1136/bmjgh-2020-003618] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2020] [Revised: 12/23/2020] [Accepted: 12/25/2020] [Indexed: 01/21/2023] Open
Abstract
Background Preterm birth is the leading cause of under-five-mortality worldwide, with the highest burden in low-income and middle-income countries (LMICs). The aim of this study was to synthesise evidence-based interventions for preterm and low birthweight (LBW) neonates in LMICs, their associated neonatal mortality rate (NMR), and barriers and facilitators to their implementation. This study updates all existing evidence on this topic and reviews evidence on interventions that have not been previously considered in current WHO recommendations. Methods Six electronic databases were searched until 3 March 2020 for randomised controlled trials reporting NMR of preterm and/or LBW newborns following any intervention in LMICs. Risk ratios for mortality outcomes were pooled where appropriate using a random effects model (PROSPERO registration number: CRD42019139267). Results 1236 studies were identified, of which 49 were narratively synthesised and 9 contributed to the meta-analysis. The studies included 39 interventions in 21 countries with 46 993 participants. High-quality evidence suggested significant reduction of NMR following antenatal corticosteroids (Pakistan risk ratio (RR) 0.89; 95% CI 0.80 to 0.99|Guatemala 0.74; 0.68 to 0.81), single cord (0.65; 0.50 to 0.86) and skin cleansing with chlorhexidine (0.72; 0.55 to 0.95), early BCG vaccine (0.64; 0.48 to 0.86; I2 0%), community kangaroo mother care (OR 0.73; 0.55 to 0.97; I2 0%) and home-based newborn care (preterm 0.25; 0.14 to 0.48|LBW 0.42; 0.27 to 0.65). No effects on perinatal (essential newborn care 1.02; 0.91 to 1.14|neonatal resuscitation 0.95; 0.84 to 1.07) or 7-day NMR (essential newborn care 1.03; 0.83 to 1.27|neonatal resuscitation 0.92; 0.77 to 1.09) were observed after training birth attendants. Conclusion The findings of this study encourage the implementation of additional, evidence-based interventions in the current (WHO) guidelines and to be selective in usage of antenatal corticosteroids, to reduce mortality among preterm and LBW neonates in LMICs. Given the global commitment to end all preventable neonatal deaths by 2030, continuous evaluation and improvement of the current guidelines should be a priority on the agenda.

Abstract
Clinical trials are essential to test the safety and efficacy of new treatments in any population. The paucity of drug trials especially in the neonatal population has led to the widespread use of unlicensed or off-label medications, exposing them to the risks of drug toxicity and ineffective treatment. Ethical and operational challenges are no longer considered valid excuses for not conducting drug trials in neonates. We recently participated in a combined phase-2 and phase-3 trial investigating a new indigenous goat lung surfactant extract (GLSE) for the treatment of respiratory distress syndrome (RDS) in preterm neonates. In this article, we share pertinent challenges faced by us during the trial to better inform and foster-positive discussion among drug developers, administrators, regulatory authorities, patient advocacy groups, and researchers. Also, we provide many tools developed for the GLSE trial that can be modified and used by prospective trialists.

Abstract
OBJECTIVE To estimate the direct causes of mortality among preterm neonates <33 weeks' gestation by examining three large multisite, hospital-based datasets in India. METHOD Three prospective hospital-based datasets: the National Neonatal Perinatal Database (NNPD) of India, the Delhi Neonatal Infection Study (DeNIS) cohort, and the Goat Lung Surfactant Extract (GLSE)-Plus cohort were analyzed to study the causes of death among preterm neonates of less than 33 weeks' gestation admitted to the participating tertiary care hospitals in India. RESULTS A total of 8024 preterm neonates were admitted in the three cohorts with 2691 deaths. Prematurity-related complications and sepsis contributed to 53.5% and 19.8% of deaths in the NNPD cohort, 51.0% and 25.0% in the DeNIS cohort, and 39.7% and 40.9% in GLSE-Plus cohort, respectively. CONCLUSIONS Nearly a quarter (20-40%) of preterm neonates less than 33 weeks' gestation admitted to Indian NICUs died of sepsis. The study results have implications for health policies targeted to reduce the neonatal mortality rate in India.
