RESUMO

OBJECTIVES: To evaluate the diagnostic utility of endotoxin and endotoxin binding protein (EBP) for the diagnosis of late-onset neonatal sepsis (LOS) and compare it with the diagnostic utility of C-reactive protein (CRP). METHODS: This diagnostic study of neonates, both term and preterm, with clinical suspicion of LOS was conducted in a tertiary care institute in India between January 2021 and March 2023. Blood samples were collected for evaluating endotoxin and EBP along with culture. Endotoxin and EBP were measured with enzyme linked immunosorbent assay, CRP was measured by nephelometry method, and the results were compared with blood culture done with BACTEC (gold standard). RESULTS: Out of 160 samples, 73 showed culture positivity. Endotoxin was positive in 81 samples and showed sensitivity of 84%, specificity of 78% and diagnostic accuracy of 81% (AUC 0.837, P value <0.001). EBP was positive in 82 samples and showed sensitivity of 80.8%, specificity of 73% and diagnostic accuracy of 76% (AUC 0.824, P value <0.001). CRP was positive in 105 samples and had sensitivity of 86%, specificity of 51% and diagnostic accuracy of 67% (AUC 0.827, P value <0.001). CONCLUSIONS: The present study showed endotoxin and EBP have higher specificity for diagnosing neonatal sepsis. As culture takes minimum 48 h, endotoxin and EBP can be utilized as biomarkers for diagnosis of sepsis.

RESUMO

Neonatal intensive care unit (NICU) admission increases parents' stress levels and it might be even higher in the crisis of coronavirus disease 2019 (COVID-19) pandemic and lockdown. This study was done to identify the stress levels of parents of admitted neonates and the difficulties encountered in neonatal care and follow-up during the COVID-19 pandemic and lockdown. The Parental Stressor Scale (PSS:NICU) and Perceived Stress Scale (PeSS) were used to identify the stress levels of parents of admitted neonates. Online survey form with a structured questionnaire comprising PeSS and NICU:PSS was sent through messaging app (Google form) after informed consent. PSS score of <14 was considered low stress, 14-26 moderate and >26 as high. A total of 118 parental responses (mother /father in 26, both in 46) for 72 admitted neonates, were obtained. The mean (SD) PeSS score was 19.7 (5.8%) and 92 (78%) had moderate stress while 11 (9%) had high stress. In NICU:PSS, sights-sounds and parental role had more median scores: 2.25 (1-3.75) and 2.21 (1-3.57), respectively. Maternal and paternal NICU:PSS (p-0.67) and PeSS (p-0.056) scores were not statistically different. Keeping nil per oral, invasive ventilation, culture-positive sepsis, fathers' transport difficulty and longer duration of mothers' and neonates' hospital stay was associated with increased NICU: PSS scores. Twenty (29%) parents could not bring their child for follow-up and there was a delay in immunisation in 21 (30%). The pandemic and the lockdown might have disrupted antenatal and postnatal follow-ups further adding to the parental stress.

RESUMO

INTRODUCTION: Kangaroo mother care (KMC) provided to stable babies in hospitals is associated with 40% relative risk reduction in death, 65% risk reduction in nosocomial infections. Despite clear existing evidence of advantages of KMC, its implementation remains limited.This study aimed to improve the median KMC practice hours in eligible preterm and low birth weight (LBW) neonates by 50% from the baseline practice. METHODS: This was a Quality Improvement study conducted at Neonatal unit of a tertiary care institute in South India. All stable preterm and LBW neonates were included after obtaining written informed consent from mother. Those who needed interruption in KMC due to medical reason were excluded. A team comprising of 2 principal investigators (UG students), 2 consultants and 2 in-charge nurses was formed. Baseline data were collected between January and February 2021 to find out the median duration of KMC practice and to identify limiting factors (barriers) and the facilitating ones through in-depth interviews and team meetings. The study was conducted over a 10 month period. Steps were taken to tackle these in two PDSA cycles, each lasting for 3 weeks (1st PDSA: Education of Mothers and Nurses; 2nd PDSA: KMC technique, orders by residents). The PDSA was followed by monitoring for 10 weeks for sustenance. RESULTS: The baseline data showed that the median duration (in hours) of KMC practice was 2.6 which increased to 5.0 and 5.5 h by the end of first and second PDSA cycle, respectively and showed a lasting change, peaking at a median value of 6.1 h during the sustenance phase over the next 10 weeks. CONCLUSION: Through simple measures and closing the communication gap between health care workers and mothers, we were able to increase the duration of KMC, which remained high during the 10 week follow up period.

RESUMO

BACKGROUND AND OBJECTIVES: Postnatal growth failure happens in about half of the very low birth weight infants and this can have long-term consequences. Human milk-based multi-nutrient fortifiers (HMBF) are thought to be better tolerated than bovine milk-based multi-nutrient fortifiers (BMBF), thus facilitating early progression to full feeds and improved growth in preterm neonates. This study was done to find the advantage of HMBF over BMBF on postnatal growth and other clinical outcomes. METHODS: This is a retrospective cohort study where babies <1500 g birth weight or gestational age <32 weeks were included to compare the velocity of weight gain (g/kg/day), duration of hospital stay and clinical outcomes between fortification using HMBF and BMBF till 34 weeks postmenstrual age. RESULTS: Eligible neonates included in the study were 322, out of whom 123 (37%) received HMBF and 209 (63%) received BMBF. During the stay, 18 babies were changed from BMBF to HMBF and vice versa in 24 babies due to logistic reasons and parents' preferences. The mean birth weight of the babies was 1124 ± 237 g. Weight gain was higher in the exclusive HMBF group [mean difference 0.77 (0.14, 1.39) g/kg/day; p-value = 0.018]. Feed intolerance [odds ratio (OR) 0.45 (0.22, 0.95), p-value 0.037] was also significantly less in this group. However, other morbidities did not differ significantly between the groups. CONCLUSION: Higher weight gain and lower feed intolerance in the HMBF group underscores the possible advantage of using HMBF over BMBF. Larger prospective studies might bring out its effect on the duration of hospital stay and other morbidities.

RESUMO

In neonates with more than one clinical abnormalities, we always look for a unifying diagnosis that explains the entire clinical presentation. In rare instances, two conditions can co-exist. Here, we report a neonate born out of consanguineous marriage presenting at 48 hours of life with microcephaly, encephalopathy, hypertonia. He had excessive weight loss, persistent hyperkalaemia, shock and elevated level of 17- hydroxyprogesterone. Steroids were started for adrenal insufficiency. Magnetic resonance imaging (MRI) of the brain revealed T2 hyperintensity of cerebral white matter, hypomyelination and parenchymal volume loss causing microcephaly. Clinical exome sequencing (CES) revealed a pathogenic homozygous missense variation of CYP21A2 gene responsible for congenital adrenal hyperplasia and also the presence of a homozygous missense variant of unknown significance (VUS) of VARS gene implicated in neurodevelopmental disorder with microcephaly, seizures, and cortical atrophy (NDMSCA). Baby was neurologically abnormal at discharge. In the setting of consanguinity, there is a possibility of two genetic conditions. Clinical exome sequencing test is useful in demystifying the diagnosis in complex clinical presentation.

RESUMO

OBJECTIVE: To reduce the incidence of metabolic bone disease (MBD) among very low birthweight (VLBW) infants admitted to neonatal intensive care unit from baseline of 35% by 50% over 2 years by implementing a quality improvement (QI) initiative. METHODS: A multidisciplinary QI team used evidence-based interventions and the healthcare improvement model to reduce MBD rate in VLBW infants. The specific interventions included routine enteral supplementation of calcium and phosphorus using Human Milk Fortifier (HMF) to expressed breast milk by day 14 of life (Plan/Do/Study/Act (PDSA) cycle 1), parenteral and early enteral supplementation of calcium and phosphorus (PDSA cycles 2 and 3). We included VLBW infants admitted within the study period at birth and excluded babies with congenital malformations, skeletal disorders and those who died before 2 weeks of age. Compliance with adding HMF by day 14, compliance with adding calcium and phosphorus in total parenteral nutrition (TPN) from day 1 of life and compliance with starting HMF when the baby reached 100 mL/kg/day of feeds were used as process indicators. The incidence of MBD was used as an outcome indicator during the study. The incidence of MBD was tracked using the Statistical Process Control methodology. RESULTS: The baseline MBD rate in 2015 was 35%. After the first PDSA cycle, 20% developed MBD (p=0.02). The same was sustained for a period of 1 year with the rate of 22%. After the second and third PDSA cycles, there was a drop in the MBD rate to 17%, and sustained for 3 months with 21%. CONCLUSION: Implementation of QI initiatives decreased the MBD rate from 35% to <20%. Early parenteral calcium and phosphorus supplementation in TPN and optimising enteral supplementation with multicomponent fortifiers appear to have significant reduction in the incidence of MBD.

RESUMO

Background: Gastrointestinal (GI) malformations have varied short-term and long-term outcomes reported across various neonatal units in India. Methods: This descriptive study was done to study the clinical profile, outcomes and predictors of mortality in neonates operated for congenital GI malformations in a tertiary neonatal care unit in South India between years 2011 and 2020. Details were collected by retrospective review of the case sheets. Results: Total of 68 neonates were included with esophageal atresia (EA) in 10, infantile hypertrophic pyloric stenosis (IHPS) in 9, duodenal atresia (DA) in 10, ileal atresia in 8, jejunal atresia in 5, anorectal malformations (ARM) in 11, meconium ileus/peritonitis in 9, malrotation in 2, and Hirschsprung's disease (HD) in 4. Antenatal diagnosis was highest in DA (80%). Associated anomalies were maximum in EA (50%), the most common being vertebral, anal atresia, cardiac defects, tracheoesophageal fistula, renal and radial abnormalities, and limb abnormalities association (VACTERL). Overall mortality was 15%. IHPS, DA, Malrotation, HD and ARM had 100 % survival while ileal atresia had the least survival (38%). Gestational age <32 weeks (odds ratio [OR] 12.77 [1.96, 82.89]) and outborn babies (OR 5.55 [1.01, 30.33]) were significant predictors of mortality in babies operated for small intestinal anomalies. None of the surviving infants were moderately or severely underweight at follow-up. Conclusion: Overall survival of surgically correctable GI anomalies is good. Among the predictors for mortality, modifiable factors such as in-utero referral of antenatally diagnosed congenital anomalies need attention. One-fifth had associated anomalies highlighting the need to actively look for the same. Although these neonates are vulnerable for growth failure, they had optimal growth on follow-up possibly due to standardized total parenteral nutritional policy during neonatal intensive care unit stay.

RESUMO

Therapeutic hypothermia is an established therapy with proven benefit for term neonates with moderate and severe hypoxic-ischemic encephalopathy (HIE). Many centers in India have started therapeutic cooling of asphyxiated infants. There is enough evidence for the beneficial effect of cooling from the randomized trials conducted in India. However, the recently published hypothermia for encephalopathy in low- and middle-income countries (HELIX) trial has contrasting findings. In this context, this review is written summarizing the available experience and evidence for therapeutic hypothermia for perinatal asphyxia in India.

RESUMO

OBJECTIVE: To adapt the Neonatal Eating Assessment Tool-Breastfeeding (NeoEAT-Breastfeeding) into Tamil, a language spoken in several South Asian countries, to identify the tool's factor structure, and to assess its psychometric properties. DESIGN: Cross-sectional. SETTING: Tertiary care hospital in South India. PARTICIPANTS: A cohort of 323 mothers of infants ages 1 week to 7 months, including infants with and without feeding difficulties. METHOD: To adapt the English tool to Tamil, we followed standard procedures specified by the tool developers and international guidelines for tool translation and adaptation, including pilot testing and personal interviews with participants who had infants younger than 7 months. Participants completed the NeoEAT-Breastfeeding (Tamil) after assessment of breastfeeding by professionals. The 62-item tool involves rating each item on a 6-point scale, and higher scores indicate increased feeding difficulties. RESULTS: After exploratory factor analysis, we divided the tool into five subscales in the Tamil version compared to the seven subscales in the original English version. The Tamil version demonstrated high internal consistency reliability (Cronbach's α = 0.97) and test-retest reliability (intraclass correlation = 0.99) for the total scores. Infants with feeding concerns demonstrated significantly higher total and subscale scores on the NeoEAT-Breastfeeding (Tamil) than infants without feeding concerns (p = .000; construct validity). CONCLUSION: The NeoEAT-Breastfeeding (Tamil) holds promise as a culturally appropriate, clinically useful parent-report tool with evidence for initial reliability and validity for identifying feeding-related concerns among infants younger than 7 months in the Tamil-speaking population.

RESUMO

BACKGROUND AND OBJECTIVES: Hypoglycemia occurs in 5% to 15% of neonates in the first few days. A significant proportion requires admission for intravenous fluids. Dextrose gel may reduce admissions and mother-infant separation. We aimed to study the utility of dextrose gel in reducing the need for intravenous fluids. METHODS: This stratified randomized control trial included at-risk infants with asymptomatic hypoglycemia. Study populations were stratified into 3 categories: small for gestational age (SGA) and intrauterine growth-restriction (IUGR), infants of diabetic mothers (IDM) and large for gestational age (LGA), and late preterm (LPT) neonates. Intervention group received dextrose gel followed by breastfeeding, and the control group (CG) received only breastfeeding. RESULTS: Among 629 at-risk infants, 291 (46%) developed asymptomatic hypoglycemia; 147 (50.4%) in the dextrose gel group (DGG) and 144 (49.6%) in CG. There were 97, 98, and 96 infants in SGA/IUGR, IDM/LGA, and LPT categories, respectively. Treatment failure in the DGG was 17 (11.5%) compared to 58 (40.2%) in CG, with a risk ratio of 0.28 (95% confidence interval [CI]: 0.17-0.46; P < .001). Treatment failure was significantly less in DGG in all 3 categories: SGA/IUGR, IDM/LGA, and LPT with a risk ratio of 0.29 (95% CI:0.13-0.67), 0.31 (95% CI:0.14-0.66) and 0.24 (95% CI:0.09-0.66), respectively. CONCLUSIONS: Dextrose gel reduces the need for intravenous fluids in at-risk neonates with asymptomatic hypoglycemia in the first 48 hours of life.

RESUMO

In neonates, rotavirus (RV) infection is generally nosocomial. The control of rotaviral infection within hospital settings is challenging due to prolonged shedding of the virus and contamination of the surrounding environment. There are few studies that have reported asymptomatic infection within neonates. In this study, neonates were screened for RV infection and possible clinical manifestations that may play a role in RV acquisition were analysed. Stool samples were collected from 523 hospitalized neonates admitted for > 48 h in a low-cost and higher-cost tertiary centre. RV antigen was screened using ELISA and the samples which tested positive were confirmed by semi-nested RT-PCR. RV was detected in 34% of participants and genotypes identified included G12P[11] (44.4%), G10 P[11] (42.6%), G10G12P[11] (10.1%) and G3P[8] (2.9%). ICU admissions were associated with higher viral shedding (p < 0.05). Hospitalization in the low-cost facility ICU was associated with higher RV acquisition risk (p < 0.05). RV was detected in higher rates (36.9%) among neonates with gastrointestinal manifestations. G10P[11] was the predominant genotype for several years (1988-2016) among neonates within India. The preponderance of an emerging G12P[11] genotype and heterotypic distribution was documented. RV surveillance is important to identify emerging strains and establish the road ahead in managing RV infection.

RESUMO

INTRODUCTION: Periventricular leukomalacia (PVL) is a result of various antenatal, intrapartum, or postnatal insults to the developing brain and is an important harbinger of cerebral palsy in preterm neonates. There is no proven therapy for PVL. This calls for appraisal of targeted therapies that have been investigated in animal models to evaluate their relevance in a clinical research context. AREAS COVERED: This systematic review identifies interventions that were evaluated in preclinical studies for neuroprotective efficacy against PVL. We identified 142 studies evaluating various interventions in PVL animal models (search method is detailed in section 2). EXPERT OPINION: Interventions that have yielded significant results in preclinical research, and that have been evaluated in a limited number of clinical trials include stem cells, erythropoietin, and melatonin. Many other therapeutic modalities evaluated in preclinical studies have been identified, but more data on their neuroprotective potential in PVL must be garnered before they can be considered for clinical trials. Because most of the tested interventions had only a partial efficacy, a combination of interventions that could be synergistic should be investigated in future preclinical studies. Furthermore, since the nature and pattern of perinatal insults to preterm brain predisposing it to PVL are substantially variable, individualized approaches for the choice of appropriate neuroprotective interventions tailored to different subgroups of preterm neonates should be explored.

RESUMO

Peritoneal dialysis (PD) is the most common form of renal replacement therapy in neonates and there is a lot of heterogeneity in patient selection and outcomes across the various units. This study aimed to assess the indications, complications, and outcomes in terms of survival of PD. This is a retrospective study of 23 neonates who underwent acute PD at a tertiary care neonatal unit between August 2016 and July 2021. A cross-sectional poll was also conducted among the doctors who have been in the unit for the past 10 years regarding their experience in PD. The baseline, clinical, biochemical parameters, outcomes, and complications were analyzed. All statistical analyses were performed using the IBM SPSS Statistics version 23.0 software. The mean (±standard deviation) gestational age and birth weights of neonates were 32.6 ± 4 weeks and 1743 ± 922 g, respectively. Six (26%) babies had extremely low birth weight, five (22%) very low birth weight (VLBW), and seven (30%) low birth weight. The indications were acute kidney injury [17/23 (74%)], fluid overload [3/23 (17%)], suspected inborn errors of metabolism [2/23 (9%)] and hypernatremia [1/23 (4%)]. A pigtail catheter (74%) was used in most of them. Catheter block was noticed in four babies and peritonitis in two neonates. We did not encounter any complications during the procedure, and PD appears to be practicable across all gestational ages and birth weights.

RESUMO

Non-bilious vomiting in preterm neonates discharged from neonatal intensive care units is a common complaint and is often associated with benign conditions such as gastro-oesophageal reflux. A neonate of 27 weeks gestation who presented later with vomiting owing to gastric outlet obstruction is described. He was discharged at 11 weeks of age and required re-admission 1 week later. He had persistent non-bilious vomiting from 7 weeks of age, failure to thrive and metabolic alkalosis. Clinical examination demonstrated visible gastric peristalsis, and hypertrophic pyloric stenosis was suspected. Ultrasound of the gastric pylorus and upper gastro-intestinal contrast studies were negative. Exploratory laparotomy after failure of conservative management revealed a thickened mucosal fold in the gastric pylorus, which was excised. Histopathology demonstrated inclusion bodies which are pathognomonic of cytomegalovirus infection. He was treated with valganciclovir for 6 weeks and was asymptomatic and thriving well at follow-up. Gastric outlet obstruction can be one of the manifestations of CMV infection of the gastro-intestinal tract. Diagnosis can be confirmed only by histopathology.Abbreviations: BPD: bronchopulmonary dysplasia; CMV: cytomegalovirus; H&E: haematoxylin and eosin; IHC: immunohistochemistry; IHPS: infantile hypertrophic pyloric stenosis; NEC: necrotising enterocolitis; PCR: polymerase-chain reaction; VGP: visible gastric peristalsis.

RESUMO

BACKGROUND: We analyzed the certainty of evidence (CoE) for risk factors of periventricular leukomalacia (PVL) in preterm neonates, a common morbidity of prematurity. METHODS: Medline, CENTRAL, Embase, and CINAHL were searched. Cohort and case-control studies and randomised randomized controlled trials were included. Data extraction was performed in duplicate. A random random-effects meta-analysis was utilizedused. CoE was evaluated as per Grading of Recommendations Assessment, Development and Evaluation (GRADE) guidelines. RESULTS: One hundred eighty-six studies evaluating 95 risk factors for PVL were included. Of the 2,509,507 neonates assessed, 16,569 were diagnosed with PVL. Intraventricular hemorrhage [adjusted odds ratio: 3.22 (2.52-4.12)] had moderate CoE for its association with PVL. Other factors such as hypocarbia, chorioamnionitis, PPROM >48 hour, multifetal pregnancy reduction, antenatal indomethacin, lack of antenatal steroids, perinatal asphyxia, ventilation, shock/hypotension, patent ductus arteriosus requiring surgical ligation, late-onset circulatory collapse, sepsis, necrotizing enterocolitis, and neonatal surgery showed significant association with PVL after adjustment for confounders (CoE: very low to low). Amongst the risk factors associated with mother placental fetal (MPF) triad, there was paucity of literature related to genetic predisposition and defective placentation. Sensitivity analysis revealed that the strength of association between invasive ventilation and PVL decreased over time (P < 0.01), suggesting progress in ventilation strategies. Limited studies had evaluated diffuse PVL. CONCLUSION: Despite decades of research, our findings indicate that the CoE is low to very low for most of the commonly attributed risk factors of PVL. Future studies should evaluate genetic predisposition and defective placentation in the MPF triad contributing to PVL. Studies evaluating exclusively diffuse PVL are warranted.

RESUMO

The rarity of congenital hypopituitarism (CHP) makes it essential for clinicians to be aware of its varying clinical manifestations. We report a neonate with one such unique presentation. A preterm girl baby was managed for respiratory distress. Diffuse cutis marmorata was present since birth; septic screens were positive with placental histopathology showing chorioamnionitis. Newborn screening showed low free thyroxine and normal TSH. Transient hypothyroxinaemia of prematurity was considered. Her respiratory status worsened on day 9, followed by refractory shock. She was treated for sepsis. Further evaluation for absent heart rate variability in response to vasopressor resistant shock led to the detection of hypocortisolism. Low cortisol along with hypothyroxinaemia made hypopituitarism the working diagnosis. Owing to the variable clinical spectrum of CHP, diagnosis is challenging. We highlight a few clinical and laboratory features, which would help in earlier diagnosis of CHP.

RESUMO

OBJECTIVES: To study the utility of clinical exome sequencing (CES) using next generation sequencing (NGS) in evaluating neonates with suspected genetic conditions. METHODS: This is an observational study conducted in a tertiary care neonatal unit. We included neonates with suspected genetic conditions, for whom CES were done either by direct sampling or from stored DNA. Data was collected from the Sri Ramachandra centre of excellence in perinatal health (SCOPE) case records of 2016-2019. Yield of CES, percentage of pathogenic, non-pathogenic and variant of uncertain significance (VUS) and associated disorders were studied. RESULTS: CES was done in 36 neonates. Variants were detected in 78% (28/36). However, significant variants with clinical correlation were present in 20 (56%) babies. Test was carried out from the stored sample in 10 (28%) babies. Mean turn-around time was 39 ± 7 days. Specialist was involved in 1 and treatment changes were done in 5 neonates. Five out of 8 VUS were clinically correlating. Inborn errors of metabolism were the commonest (60%). Two VUS were ascertained as likely pathogenic after parental segregation analysis. CONCLUSION: CES has a definite role in evaluation of suspected genetic conditions for diagnosis and prognostication. It also helps scientific society to build in additional evidence so that the "VUS" could be asserted as "likely pathogenic" . Our experience reiterates the importance of storing and archiving DNA of the affected child.

RESUMO

Clinical profile of extreme preterm neonates and more so, of microprimies with birth weight < 800 g is not studied till now. Our article elaborates the profile of 5 microprimies with C.auris sepsis and review of literature. The mean gestational age and birth weight were 26 weeks ± 5 days and 709 ±â€¯64 g respectively. Mortality was 80%. The organism was susceptible to micafungin, voriconazole but was resistant to fluconazole and amphotericin. Among the 5 babies, one had organ involvement in the form of cardiac vegetation. Early identification and optimal choice of drug are crucial for better survival in C.auris sepsis.
