Comparative efficacies of vitamin D supplementation regimens in infants: a systematic review and network meta-analysis.

Vitamin D deficiency in infants is widely prevalent. Most paediatric professional associations recommend routine vitamin D prophylaxis for infants. However, the optimal dose and duration of supplementation are still debated. We aimed to compare the efficacy and safety of different vitamin D supplementation regimens in term and late preterm neonates. For this systematic review and network meta-analysis, we searched MEDLINE, the Cochrane Central Register of Controlled Trials and Embase. Randomised and quasi-randomised clinical trials that evaluated any enteral vitamin D supplementation regimen initiated within 6 weeks of life were included. Two researchers independently extracted data on study characteristics and outcomes and assessed quality of included studies. A network meta-analysis with a Bayesian random-effects model was used for data synthesis. Certainty of evidence (CoE) was assessed using GRADE. Primary outcomes were mean serum vitamin D concentrations and the proportion of infants with vitamin D insufficiency (VDI). We included twenty-nine trials that evaluated fourteen different regimens of vitamin D supplementation. While all dosage regimens of ≥400 IU/d increased the mean 25(OH)D levels compared with no treatment, supplementation of ≤250 IU/d and 1400 IU/week did not. The CoE varied from very low to high. Low CoE indicated that 1600 IU/d, compared with lower dosages, reduced the proportion of infants with VDI. However, our results indicated that any dosage of ≥800 IU/d increased the risk of hypervitaminosis D and hypercalcaemia. Data on major clinical outcomes were sparse. Vitamin D supplementation of 400-600 IU/d may be the most effective and safest in infants.

Morpho-histology of co-occurrence of somatic embryos, shoots, and inflorescences within a callus of Limonium 'Misty Blue'.

This is the first attempt to report the co-occurrence of somatic embryos, shoots, and inflorescences and their sequential development from stem cell niches of an individual callus mass through morpho-histological study of any angiosperm. In the presence of a proper auxin/cytokinin combination, precambial stem cells from the middle layer of a compact callus, which was derived from the thin cell layer of the inflorescence rachis of Limonium, expressed the highest level of totipotency and pluripotency and simultaneously developed somatic embryos, shoots, and inflorescences. This study also proposed the concept of programmed cell death during bipolar somatic embryo and unipolar shoot bud pattern formation. The unique feature of this research was the stepwise histological description of in vitro racemose inflorescence development. Remarkably, during the initiation of inflorescence development, either a unipolar structure with open vascular elements or an independent bipolar structure with closed vascular elements were observed. The protocol predicted the production of 6.6 ± 0.24 and 7.4 ± 0.24 somatic embryos and shoots, respectively, from 400 mg of callus, which again multiplied, rooted, and acclimatised. The plants' ploidy level and genetic fidelity were assessed randomly before acclimatisation by flow cytometry and inter simple sequence repeats (ISSR) marker analysis. Finally, the survivability and flower quality of the regenerated plants were evaluated in the field.

A short-term follow-up study on breastfeeding practices, growth parameters and immunization practices among babies born to COVID-19 positive mothers in a tertiary care hospital.

We aimed to study the impact of the COVID-19 pandemic on exclusive breastfeeding (EBF) rate and routine follow-up practices including immunization. A total of 62 neonates born to COVID-19 positive mothers and an equal number of neonates born to COVID-19 negative mothers were prospectively evaluated for EBF rate and routine neonatal follow-up practices including delay (>7 days) in routine immunization at 3 months follow-up. We further tried to compare the results across two epochs (epoch 1, March-June 2020 and epoch 2, July-November 2020). There was significantly lesser number of babies born to COVID-19 positive mothers on EBF at 3 months of age when compared with the control group (45.1% vs. 96.7%, p = 0.00) as well it was significantly lesser in epoch 1 when compared with epoch 2 (16% vs. 74%, p = 0.00). Further, a significantly higher number of babies born to COVID-19 positive mothers had their routine immunization delayed with no significant difference across the epochs. There was no significant difference in growth parameters between babies born to COVID-19 positive mother when compared with the control group as well as across the epochs. The COVID-19 pandemic has significantly disrupted the EBF rates as well as hampered the routine immunization practices among babies born to COVID-19 positive mothers. Although such practices got improved after the implementation of evidence-based national guidelines, but it is still much below when compared with those born to COVID-19 negative mother.

Diagnostic Utility of Cerebrospinal Fluid Procalcitonin in Neonatal Meningitis.

We aimed to study the diagnostic utility of cerebrospinal fluid (CSF) procalcitonin (PCT) in neonates with meningitis. All the neonates with sepsis who qualified for lumbar puncture were prospectively evaluated. The neonates were classified into Meningitis and No meningitis group based on predefined criteria. CSF PCT was estimated in these neonates along with cytological and biochemical parameters. A total of 113 neonates were included in the study with 29 in the meningitis group and 84 in the no meningitis group. The median PCT levels were higher in babies with meningitis as compared to those without meningitis [0.194 (0.034-0.534) in meningitis group vs. 0.012 (0.012-0.012) ng/ml in no meningitis group, p < 0.001]. The area under curve for CSF PCT was 0.867 (0.77-0.95) and at a cut-off level of 0.120 ng/ml CSF PCT had a sensitivity of 83%, specificity of 84% and positive and negative predictive likelihood ratios of 5.35 and 0.20, respectively for the diagnosis of meningitis. CSF PCT has a good diagnostic accuracy similar to other parameters in the diagnosis of neonatal meningitis and can be considered as an additional diagnostic marker particularly when CSF culture is negative and cytochemical analysis is inconclusive.

Enteral Feeding Strategies in Preterm Neonates ≤32 weeks Gestational Age: A Systematic Review and Network Meta-Analysis.

INTRODUCTION: Critical aspects of time of feed initiation, advancement, and volume of feed increment in preterm neonates remain largely unanswered. METHODS: Medline , Embase, CENTRAL and CINAHL were searched from inception until 25th September 2020. Network meta-analysis with the Bayesian approach was used. Randomized controlled trials (RCTs) evaluating preterm neonates ≤32 weeks were included. Feeding regimens were divided based on the following categories: initiation day: early (<72 h), moderately early (72 h-7 days), and late (>7 days); advancement day: early (<72 h), moderately early (72 h-7 days), and late (>7 days); increment volume: small volume (SV) (<20 mL/kg/day), moderate volume (MoV) (20-< 30 mL/kg/day), and large volume (≥30 mL/kg/day); and full enteral feeding from the first day. Sixteen regimens were evaluated. Combined outcome of necrotizing enterocolitis (NEC) stage ≥ II or mortality before discharge was the primary outcome. RESULTS: A total of 39 studies enrolled around 6,982 neonates. Early initiation (EI) with moderately early or late advancement using MoV increment enteral feeding regimens appeared to be most efficacious in decreasing the risk of NEC or mortality when compared to EI and early advancement with SV increment (risk ratio [95% credible interval]: 0.39 [0.12, 0.95]; 0.34 [0.10, 0.86]) (GRADE-very low). CONCLUSIONS: Early initiated, moderately early, or late advanced with MoV increment feeding regimens might be most appropriate in decreasing the risk of NEC stage ≥II or mortality. In view of the certainty of evidence being very low, adequately powered RCTs evaluating these 2 strategies are warranted.

Long-Term Neurodevelopmental Outcomes of Neonatal Chikungunya: Follow-Up of a Series of Cases Till 1 Year.

OBJECTIVES: Short- or long-term neurodevelopmental outcomes of Neonatal Chikungunya infection haven't been well described. In this study, we describe neurodevelopmental outcomes of a series of 13 infants. METHODS: Study was conducted over a period of 1 year in high-risk follow-up clinic. Follow-up visits were conducted at 3, 6, 9, 12 ± 3 months. PRIMARY OUTCOME: Development Quotient by Developmental Assessment Scales for Indian Infants. Secondary outcome: growth/anthropometric assessment, neuromotor/neurosensory and re-hospitalization rate. RESULTS: DASII was <85 in three infants. Two other had expressive speech delay. Two, three and four babies had head circumference, length and weight below third centile, respectively. Two infants had persistent hypertonia and one had hypotonia. Two infants developed strabismus. Two infants had seizures persisting at 12 months requiring re-hospitalization. CONCLUSION: Neonatal Chikungunya infection portends a poor neurodevelopmental outcome at 1 year of age. Careful neurodevelopmental follow-up is required for identification and management of sequelae.

Possible Early Vertical Transmission of COVID-19 from an Infected Pregnant Female to Her Neonate: A Case Report.

Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-19) has emerged as a public health emergency in recent times. The reported data on the mode of transmission of coronavirus disease 2019 (COVID-19) are largely through contact, droplet, airborne and fomite transmission methods with vertical transmission being a rare entity. We hereby report a case of a probable vertical transmission of SARS-CoV-19 from an infected pregnant female to her neonate. The transmission has been confirmed by a positive RT-PCR at 16 h of life along with a positive IgG antibody test for SARS-CoV-19 in the baby and after excluding the possible environmental contamination of the sample. The baby was asymptomatic during the course of hospital stay and was discharged from the facility on Day 9 of life.

A tetrad apparatus for protein gel casting, electrophoresis, staining, and scanning techniques with dual sensors for automatic detection of gel polymerization and protein migration.

Recent advancements in biochemical sciences have facilitated researchers to explore the structure and function of macro molecules in a cell. PAGE is one of the most favored and adapted laboratory techniques. Due to its simple and economical procedures, several variants or new modifications are routinely observed in the basic electrophoresis technique that comprises gel casting, electrophoresis, staining, and imaging process which consequently necessitates additional apparatuses/components in the laboratory. Operation of these additional apparatuses/components lengthens the pre- and postelectrophoresis procedures involving many intermittent tedious and time-consuming steps. A universal apparatus that can facilitate all such associated techniques is lacking and is of utmost importance for fast and effective results. An apparatus that can perform synchronized action of slab gel casting (16 × 16 cm), electrophoresis (SDS-PAGE), dye staining (Coomassie), and imaging (scanning) techniques with real-time monitoring through sensor technology is described in this article. The estimated cost (∼$150) of fabrication of the apparatus is very economical and simple assembly procedure of the main apparatus can be completed within ∼30 min after fabrication.

Multi-gel casting apparatus for vertical polyacrylamide gels with in-built solution flow system and liquid level detectors.

PAGE is the most widely used technique for the separation and biochemical analysis of biomolecules. The ever growing field of proteomics and genomics necessitates the analysis of many proteins and nucleic acid samples to understand further about the structure and function of cells. Simultaneous analysis of multiple protein samples often requires casting of many PAGE gels. Several variants of multi-gel casting/electrophoresis apparatuses are frequently used in research laboratories. Requirement of supplementary gels to match the growing demand for analyzing additional protein samples sometimes become a cause of concern. Available apparatuses are not amenable to and therefore, not recommended for any modification to accommodate additional gel casting units other than what is prescribed by the manufacturer. A novel apparatus is described here for casting multiple PAGE gels comprising four detachable components that provide enhanced practicability and performance of the apparatus. This newly modified apparatus promises to be a reliable source for making multiple gels in less time without hassle. Synchronized functioning of unique components broaden the possibilities of developing inexpensive, safe, and time-saving multi-gel casting apparatus. This apparatus can be easily fabricated and modified to accommodate desired number of gel casting units. The estimated cost (∼$300) for fabrication of the main apparatus is very competitive and effortless assembly procedure can be completed within ∼30 min.

A study of oxidative stress in neonates delivered through meconium-stained amniotic fluid.

To estimate the levels of malondialdehyde (MDA) and 8-hydroxy-2-deoxyguanosine (8-OH-dG) in cord blood plasma of newborns born through meconium-stained amniotic fluid (MSAF) and also to find out the correlation between their levels with birth weight and gestation, we measured the cord blood plasma levels of MDA and 8-OH-dG in 59 newborns born through MSAF and 50 newborns born through clear liquor. The levels of cord blood plasma MDA and 8-OH-dG were significantly higher in full-term and late-preterm newborns born through MSAF. On further comparison, it was found that both full-term and late-preterm intrauterine growth restricted (IUGR) neonates had higher levels of these markers as compared to babies born as appropriate for gestational age (AGA) through MSAF. Plasma levels of MDA and 8-OH-dG were significantly correlated with birth weight even after controlling the relationship with gestational age for all cases as well as all full-term cases. These markers are also significantly correlated to each other. CONCLUSIONS: The present study suggest that the neonates born through MSAF experience higher degrees of oxidative stress, as evidenced by increased levels of cord blood plasma MDA and 8-OH-dG. What is known: • Aspirated meconium has been found to induce free radical generation and cellular damage in animal studies. • Its role in free radical generation and oxidative damage in human neonates is scarce. What is new: • Neonates born through meconium-stained amniotic fluid experience significant oxidative stress.

Solitary Pleural Fibroma: A Case Report and Review of Literature.

Solitary fibrous tumors ofthe pleura (SFTP) are uncommon. They tend to be discovered incidentally or during workup for unexplained cough or paraneoplastic effects. It is important to recognize the entityand perform a surgical excision because of the possibility of subsequent malignant transformation and local compressive effects. We present the case of a SFTP discovered on chest imaging. Our patient had surgical excision with good response. A review of the literature is also presented.

A monophasic solution for isolation of RNA devoid of polymerase chain reaction-detectable genomic DNA contamination.

Commercially available reagents and published protocols are widely used for RNA isolation. However, genomic DNA contamination in isolated RNA is a potential problem. Here we describe a simple, inexpensive method for eliminating genomic DNA contamination beyond the level of PCR-based detection through reduction of the guanidine thiocyanate concentration (1.5M) in a single monophasic solution based on Chomczynski-Sacchi reagents. The new method can be used to isolate small and large RNA species of high quality and can be completed within an hour.

Identification and validation of a new male sex-specific ISSR marker in pointed gourd (Trichosanthes dioica Roxb.).

The aim of the present study was to develop a genetic sex marker for the pointed gourd (Trichosanthes dioica Roxb.) to allow gender determination at any stage in the life cycle. Screening of genomic DNA with intersimple sequence repeat (ISSR) primers was used to discover sex-specific touch-down polymerase chain reaction (Td-PCR) amplification products. Using pooled DNA from male and female genotypes and 42 ISSR primers, a putative male specific marker (~550 bp) was identified. DNA marker specific to male is an indication of existence of nonepigenetic factors involved in gender development in pointed gourd. The ISSR technique has proved to be a reliable technique in gender determination of pointed gourd genotypes at the seedling phenophase. The sex marker developed here could also be used as a starting material towards sequence characterization of sex linked genes for better understanding the developmental as well as evolutionary pathways in sexual dimorphism.

Operated bronchial carcinoids: clinical outcomes and long-term follow-up of a single institution series of 30 patients.

BACKGROUND: Bronchial carcinoids (BCs) are infrequent neoplasms that account for only 1% to 2% of all lung tumors. We reviewed the outcomes and long-term follow-up data of all patients diagnosed with BC and treated surgically at our institution between the years 2002-2009. PATIENTS AND METHODS: We analyzed the records of all patients with BC treated between January 1, 2002 and December 31st, 2009. The results were subsequently compared with the previously published data. RESULTS: Our records identified a total of 28 patients with typical carcinoids (TC) and two patients with atypical carcinoids (AC). Of these, 22 were women and eight were men with a median age of 62 (range, 23-91 years). About two-thirds of patients were symptomatic at presentation. Central and peripheral tumor location was encountered with equal frequency, with 63.3% of tumors being located in the right lung. Bronchoscopic biopsy revealed the diagnosis in 92.3% of cases. Twenty percent of patients underwent lung sparing procedures, 73.3% underwent lobectomies, and 6.7% had pneumonectomies. Mediastinal lymphadenectomy was performed in all patients. Two patients had positive nodal metastases, one of whom survived for only 10 months. Tumor recurrence was noted in two patients with TC (7.14%) and in one patient with AC. The overall five-year survival was 90% (27/30) for the entire cohort. CONCLUSIONS: Histological characteristics and nodal status probably represent the most important prognostic factors in persons with operated BCs. The female prevalence recorded in our cohort appears to contrast with previously reported almost equal gender distribution. The slightly lower percentage of lung-sparing procedures in our patients could be explained by their more advanced disease state, with tumor extension to more than one lung lobe.

A Study of General Movement Assessment and Its Association With Neurodevelopmental Outcome at Age 12 to 15 Months Among Term Neonates With Hyperbilirubinemia.

BACKGROUND: To determine the association between optimality score at term age and age three to five months and neurodevelopmental outcome among neonates with hyperbilirubinemia. METHODS: Fifty infants with and without hyperbilirubinemia were enrolled. The motor repertoires of the infants were evaluated through general movement assessment (GMA) at term age and three to five months post-term. The association between the General Movement Optimality Score (GMOS), Motor Optimality Score (MOS), and Development Assessment Scale for Indian Infants (DASII) at age 12 to 15 months was also assessed. RESULTS: During term age, the median GMOS was significantly lower among infants in the study group when compared with the control group (40 [29 to 42] vs 42 [42 to 42], P < 0.001). However, at age three to five months, there was no significant difference between the groups. Significantly higher number of neonates had abnormal motor repertoire at term age and age three to five months in the study group when compared with the control group (18 [36%] vs 2 [4%], P = 0.001, at term age and 6 [12.2%] vs 1 [2%], P =0.04, at age three to five months). Among neonates with hyperbilirubinemia, the median GMOS and MOS were significantly lower at term age and age three to five months in infants with motor and mental developmental quotient scores <85 when compared with ≥85. CONCLUSIONS: GMA including GMOS and MOS performed in neonates with hyperbilirubinemia during the neonatal period and early infancy is associated with neurodevelopmental outcomes in the first year of life. GMA can help initiate early intervention in such neonates.

Direct Shoot From Root and True-to-Type Micropropagation of Limonium "Misty Blue" in Partially Immersed Culture on an Aluminum Mesh Raft.

Commercial plant tissue culture now primarily serves the ornamental horticulture industry. The main pillars of the commercial tissue culture business are scalability of production, cost reduction, limited labor involvement, high quality, and genetic homogeneity of propagated plants. Based on these requirements, the current protocol employs a partially immersed liquid culture medium supported by a flexible aluminum mesh raft with a wire stand to facilitate shoot organogenesis from the horizontally placed root explants and hold the plants upright for shoot multiplication and rooting of Limonium Misty Blue. It is a florist crop that is in high demand as both dried and fresh flower fillers in various floral decorations. The majority of cultivated Limonium or statice cultivars are heterozygous in nature and propagate commercially through in vitro propagation to cater to the huge demand for planting materials needed for flower production. This is the first protocol to describe direct shoot organogenesis from the roots in a liquid half-component of Murashige and Skoog's (1962) (MS) basal medium supplemented with 1.6 µM NAA and 1.1 µM BA. The regenerated shoots are multiplied and rooted at the same time on the raft in a MS-based liquid culture medium that included 0.44 µM BA and 1.07 µM NAA. In comparison to agar-gelled medium, plants cultured in liquid medium grow more quickly without any signs of hyperhydricity. In liquid medium, a clump of 4-5 shoots is formed from a single shoot explant within 4 weeks and are rooted simultaneously within 6 weeks. On average, seven explants may fit on each raft, so on average, 25 healthy plants are produced from a single bottle. The regenerated plants are easily hardened in the greenhouse, and using ISSR-based molecular markers, the genetic homogeneity of the randomly selected hardened plants can be determined.

Pre-feeding premature infant oral motor intervention (PIOMI) for transition from gavage to oral feeding: A randomised controlled trial.

PURPOSE: To assess the performance of premature infant oral motor intervention for transition from gavage to full spoon feeding in preterm infants. METHODS: Preterm neonates born between 28 + 0-32 + 6 weeks gestation (n = 32) were randomised into an intervention group (premature infant oral motor intervention) for five minutes twice a day along with routine care (n = 16) and a control group (routine care, n = 16) once they reached a feed volume of at least 150 ml/kg/day administered by gavage method. The primary outcome measure was time (in days) to transition from gavage to full spoon feeds. RESULTS: The mean (SD) time to transition from gavage to full spoon feeds was attained significantly earlier in the intervention group than the control group (9.93 [5.83] vs 16.43 [10.46] days; mean difference, -6.5 days; 95% CI, -12.58 to -0.41). There was no significant difference between the two groups in terms of the duration of hospital stay, rates of physiological stability, and culture positive sepsis. CONCLUSION: Premature infant oral motor intervention, as used in this specific population, significantly reduces the time to transition to full spoon feeds without increasing culture positive sepsis and physiological instability.

Sonographic assessment of diaphragmatic thickness and excursion to predict CPAP failure in neonates below 34 weeks of gestation: A prospective cohort study.

BACKGROUND: To evaluate the diagnostic accuracy of sonographic assessment of diaphragmatic dimensions and excursions in predicting Continuous Positive Airway Pressure (CPAP) failure in preterm neonates with respiratory distress. METHODS: Prospective cohort study among preterm neonates less than 34 weeks of gestation who were hemodynamically stable and either admitted with respiratory distress or who developed respiratory distress shortly after admission to the NICU and having Silverman-Anderson Score (SAS) ≥ 3/10 were included. We performed sonographic assessment of diaphragmatic dimensions and excursions before and one hour ±30 minutes after application of CPAP. 'CPAP failure' was defined as combined outcome of the need of surfactant and/or upgradation of respiratory support within first 72 hours after a trial of CPAP. Clinical parameters and diaphragmatic measurements were compared between CPAP failure and success groups. RESULTS: Of 62 participants, 20 (32%) failed CPAP. On binomial logistic regression (after adjustment for gestational age and birth weight), initial SAS, higher diaphragmatic excursion (both left and right, before and after CPAP application), lower left hemidiaphragm diaphragmatic thickness fraction (DTF) (before CPAP application) and lower right DTF (after CPAP application) were independent predictors of CPAP failure. However, the receiver-operating characteristics curves showed that excursions of right and left hemi-diaphragm both before and after CPAP application, had highest accuracies in predicting CPAP failure (AUC 0.84, 0.80 and 0.86, 0.78, respectively; p < .001). CONCLUSION: Diaphragmatic excursion can be a useful parameter to predict the failure of CPAP in preterm neonates with respiratory distress.

Clinical decision thresholds for surfactant administration in preterm infants: a systematic review and network meta-analysis.

Background: The ideal threshold at which surfactant administration in preterm neonates with respiratory distress syndrome (RDS) is most beneficial is contentious. The aim of this systematic review was to determine the optimal clinical criteria to guide surfactant administration in preterm neonates with RDS. Methods: The systematic review was registered in PROSPERO (CRD42022309433). Medline, Embase, CENTRAL and CINAHL were searched from inception till 16th May 2023. Only randomized controlled trials (RCTs) were included. A Bayesian random effects network meta-analysis (NMA) evaluating 33 interventions was performed. The primary outcome was requirement of invasive mechanical ventilation (IMV) within 7 days of life. Findings: 58 RCTs were included. In preterm neonates ≤30 weeks after adjusting for the confounding factor of modality of surfactant administration, an arterial alveolar oxygen tension ratio (aAO2) <0.36 (FiO2: 37-55%) was ranked the best threshold for decreasing the risk of IMV, very low certainty. Further, surfactant administration at an FiO2 40-45% possibly decreased mortality compared to rescue treatment when respiratory failure was diagnosed, certainty very low. The reasonable inference that could be drawn from these findings is that surfactant administration may be considered in preterm neonates of ≤30 weeks' with RDS requiring an FiO2 ≥ 40%. There was insufficient evidence for the comparison of FiO2 thresholds: 30% vs. 40%. The evidence was sparse for surfactant administration guided by lung ultrasound. For the sub-group >30 weeks, nebulized surfactant administration at an FiO2 < 30% possibly increased the risk of IMV compared to Intubate-Surfactant-Extubate at FiO2 < 30% and 40%, and less invasive surfactant administration at FiO2 40%, certainty very low. Interpretation: Surfactant administration may be considered in preterm neonates of ≤30 weeks' with RDS if the FiO2 requirement is ≥40%. Future trials are required comparing lower FiO2 thresholds of 30% vs. 40% and that guided by lung ultrasound. Funding: None.

Placental Transfusion Strategies in Preterm Infants in Low- and Middle-Income Countries: A Systematic Review and Network Meta-Analysis.

INTRODUCTION: Placental transfusion strategies in preterm newborns have not been evaluated in low- and middle-income countries (LMICs). The objective of this systematic review was to compare placental transfusion strategies in preterm newborns in LMICs, including delayed cord clamping (DCC) for various time intervals, DCC until cord pulsations stop, umbilical cord milking, and immediate cord clamping (ICC). METHODS: Medline, Embase, CINAHL, and CENTRAL were searched from inception. Observational studies and randomized controlled trials (RCTs) were included. Two authors independently extracted data for Bayesian random-effects network meta-analysis (NMA) if more than 3 interventions reported an outcome or a pairwise meta-analysis was utilized. RESULTS: Among newborns <34 weeks of gestation, NMA of 9 RCTs could not rule out benefit or harm for survival from DCC 30-60 s compared to ICC: relative risk (RR) (95% credible interval) 0.96 (0.78-1.12), moderate certainty, or any included strategy compared to each other (low to very low certainty). Among late preterm newborns, DCC 120 s might be associated with improved survival: RR (95% confidence interval) 1.11 (1.01-1.22), very low certainty. We could not detect differences in the risk of intraventricular hemorrhage grade > II and bronchopulmonary dysplasia for any included intervention (low to very low certainty). DCC 60 s and 120 s might improve the hematocrit level among all preterm newborns (very low certainty), and DCC 45 s may decrease the risk of receipt of inotropes among newborns <34 weeks of gestation (low certainty). CONCLUSIONS: In LMICs, DCC for 60 s and 120 s might improve hematocrit level in preterm newborns, and DCC for 45 s may decrease the risk of receipt of inotropes in newborns <34 weeks, with no conclusive effect on survival.
