RESUMO
BACKGROUND: Diuretics are commonly used in neonatal AKI with the rationale to decrease positive fluid balance in critically sick neonates. The patterns of furosemide use vary among hospitals, which necessitates the need for a well-designed study. METHODS: The TINKER (The Indian Iconic Neonatal Kidney Educational Registry) study provides a database, spanning 14 centres across India since August 2018. Admitted neonates (≤ 28 days) receiving intravenous fluids for at least 48 h were included. Neonatal KDIGO criteria were used for the AKI diagnosis. Detailed clinical and laboratory parameters were collected, including the indications of furosemide use, detailed dosing, and the duration of furosemide use (in days). RESULTS: A total of 600 neonates with AKI were included. Furosemide was used in 8.8% of the neonates (53/600). Common indications of furosemide use were significant cardiac disease, fluid overload, oliguria, BPD, RDS, hypertension, and hyperkalemia. The odds of mortality was higher in neonates < 37 weeks gestational age with AKI who received furosemide compared to those who did not receive furosemide 3.78 [(1.60-8.94); p = 0.003; univariate analysis] and [3.30 (1.11-9.82); p = 0.03]; multivariate logistic regression]. CONCLUSIONS: In preterm neonates with AKI, mortality was independently associated with furosemide treatment. The furosemide usage rates were higher in neonates with associated co-morbidities, i.e. significant cardiac diseases or surgical interventions. Sicker babies needed more resuscitation at birth, and died early, and hence needed shorter furosemide courses. Thus, survival probability was higher in neonates treated with long furosemide courses vs. short courses.

BACKGROUND: Neonates admitted in the neonatal intensive care unit are vulnerable to acute kidney injury leading to worse outcomes. It is important to identify "at-risk" neonates for early preventive measures. METHODS: The study was a multicenter, national, prospective cohort study done in 11 centers in India. A multivariable logistic regression technique with step-wise backward elimination method was used, and a "Risk Prediction Scoring" was devised [the STARZ score]. RESULTS: The neonates with admission in the NICU within <25.5 h of birth, requirement of positive pressure ventilation in the delivery room, <28 weeks gestational age, sepsis, significant cardiac disease, urine output <1.32 ml/kg/h or serum creatinine ≥0.98 mg/dl during the first 12 h post admission, use of nephrotoxic drugs, use of furosemide, or use of inotrope had a significantly higher risk of AKI at 7 days post admission in the multivariate logistic regression model. This scoring model had a sensitivity of 92.8%, specificity of 87.4% positive predictive value of 80.5%, negative predictive value of 95.6%, and accuracy of 89.4%. CONCLUSIONS: The STARZ neonatal score serves to rapidly and quantitatively determine the risk of AKI in neonates admitted to the neonatal intensive care unit. IMPACT: The STARZ neonatal score serves to rapidly and quantitatively determine the risk of AKI in neonates admitted to the neonatal intensive care unit. These neonates with a higher risk stratification score need intense monitoring and daily kidney function assessment. With this intensification of research in the field of AKI risk stratification prediction, there is hope that we will be able to decrease morbidity and mortality associated with AKI in this population.

BACKGROUND: Neonatal acute kidney injury (AKI) is common in neonatal intensive care units (NICU) and leads to worse outcomes. Stratifying neonates into an "at risk" category allows health care providers to objectively recognize opportunities for improvements in quality of care. METHODS: The "Neonatal AKI Risk Prediction Scoring" was devised as the "STARZ [Sethi, Tibrewal, Agrawal, Raina, waZir]" Score. The STARZ score was derived from our prior multicentre study analysing risk factors for AKI in neonates admitted to the NICU. This tool includes 10 variables with a total score ranging from 0 to 100 and a cut-off score of 31.5. In the present study, the scoring model has been validated in our multicentre cohort of 744 neonates. RESULTS: In the validation cohort, this scoring model had sensitivity of 82.1%, specificity 91.7%, positive predictive value 81.2%, negative predictive value 92.2% and accuracy 88.8%. Based on the STARZ cut-off score of ≥ 31.5, an area under the receiver operating characteristic (ROC) curve was observed to be 0.932 (95% CI, 0.910-0.954; p < 0.001) signifying that the discriminative power was high. In the validation cohort, the probability of AKI was less than 20% for scores up to 32, 20-40% for scores between 33 and 36, 40-60% for scores between 37 and 43, 60-80% for scores between 44 and 49, and ≥ 80% for scores ≥ 50. CONCLUSIONS: To promote the survival of susceptible neonates, early detection and prompt interventional measures based on highly evidenced research is vital. The risk of AKI in admitted neonates can be quantitatively determined by the rapid STARZ scoring system. A higher resolution version of the Graphical abstract is available as Supplementary information.

Background: Feeding abilities of preterm neonates differ based on their gestational and postnatal maturity. Maturity of sucking pattern and improved coordination between sucking and swallowing and breathing, which is seen in babies with a gestation of 32 weeks onward, makes trial of oral feeds more successful in these babies. The oral feeds can be given either with a cup and spoon or a paladai. However, we observed that the milk spilt during feeding was an issue due to a wider spout of the paladai. Feeding through syringe is practiced in many neonatal units. However, there is a lack of scientific literature regarding the syringe feeding of neonates. We hypothesized that giving oral feeds using a syringe could reduce the spillage of milk. This study was done to compare the volume of feeds wasted (spillover) during oral feeding between paladai and syringe feeding. Methods: The order of feeding of 75 nurse baby pairs was randomized to either the syringe or the paladai groups. The volume of milk spilt was assessed by weighing a gauze pad placed under the neck of the baby before and after feeds. Time taken to complete the feeds, the rate of feeding, and events like vomiting and choking after feeding were noted. Feeding satisfaction among the nurses was recorded on a 5-point Likert scale. Results: The average mean time for completion of feeds by paladai was 9 minutes against 8.9 minutes in syringe feeding. The median rate of feeding was 3.57 minutes in the paladai group and 3.5 minutes in the syringe group. The median spillover volume was 3.33 mL in the paladai feeds and 3.23 mL in the intervention group. Seventy percent of the nurses reported better satisfaction with syringe feeds compared to paladai feeds. Conclusion: This study demonstrates that the milk spillover (wastage) during syringe feeding is not different from paladai feeds. However, the majority of nurses felt the syringe feeding was more satisfactory than paladai feeding. CTRI Reg. No: CTRI/2021/05/033479 dated 07.05.2021.

OBJECTIVE: To compare the variation of feeding rate and time taken for feeds between manual and automated feeding via feed rail. METHODS: Stable preterm babies weighing between 1 and 2 kg, on partial or full enteral feeds via gavage were randomized into gravity and feed rail feeding group, respectively. Ten nurses and 4 babies were paired to form 40 nurse-baby pairs for the study. Forty feeding events in each groups were recorded. RESULTS: The median duration of feeding in the feed rail group was 18.5 min compared to 15 min in nurse-led feeding (p = 0.34). Feeding rate corrected for bodyweight ranged between 0.8 and 2.3 mL/kg/min in the feed rail group compared to 2.5 and 8.9 mL/kg/min in the control (manual gravity feed) group. This difference in the feed rate variation was statistically significant (p value of <0.0001). The median feed rate with feedrail was 1.3 mL/min as compared to 4.1 mL/min with manual gravity feeds. During the feed rail feeding, nurses were hands-free for 80% of the time. CONCLUSION: Feed rail feeding results in slow, sustained, and minimal variation in gravity feeding at a rate of 1 to 2 mL/kg/min without affecting the feeding duration compared to manual nurse-led feeding.

OBJECTIVE: A rapid AKI risk assessment score would allow for improving management and outcomes. STARZ (Sethi, Tibrewal, Agrawal, Raina, waZir) score was developed for acute kidney injury (AKI) risk stratification of critically ill neonates. This is the first independent validation for the novel score outside the original enrolled centres. STUDY DESIGN: 750 neonates were included in the study. The STARZ score was calculated after 12 hours of admission. Neonates admitted in NICU and receiving IV fluids for at least 48 hours were included. RESULTS: A total of 8.8% neonates had AKI in the first 7 days post admission. The duration of hospital stay was significantly higher among neonates with AKI [10.5 (7-19) vs. 7 (5-10) days; pâ<â0.001]. Mortality risk was 6.4 times higher among those with AKI [8 (12.1%) vs. 13 (1.9%); pâ<â0.001; RR (95% CI): 6.38 (2.74-14.83)]. In this study, the STARZ neonatal scoring model showed a sensitivity of 89.4% in detecting AKI with a 90.9% specificity and a high negative predictive value of 98.9%. The area under ROC was 0.958 (0.934-0981) - a high discriminative power. CONCLUSIONS: The STARZ score allows for AKI risk stratification, providing opportunity for therapeutic interventions which may improve outcomes in critically ill neonates.

BACKGROUND: Acute kidney injury (AKI) is common in neonates admitted to neonatal intensive care units (NICUs). There is a need to have prospective data on the risk factors and outcomes of acute peritoneal dialysis (PD) in neonates. The use of kidney replacement therapy in this population compared to older populations has been associated with worse outcomes (mortality rates 17-24%) along with a longer stay in the NICU and/or hospital. METHODS: The following multicentre, prospective study was derived from the TINKER (The Indian PCRRT-ICONIC Neonatal Kidney Educational Registry) database, assessing all admitted neonates ≤28 days who received intravenous fluids for at least 48 h. The following neonates were excluded: death within 48 h, presence of any lethal chromosomal anomaly, requirement of congenital heart surgery within the first 7 days of life and those receiving only routine care in nursery. Demographic data (maternal and neonatal) and daily clinical and laboratory parameters were recorded. AKI was defined according to the Neonatal Kidney Disease: Improving Global Outcomes criteria. RESULTS: Of the included 1600 neonates, a total of 491 (30.7%) had AKI. Of these 491 neonates with AKI, 44 (9%) required PD. Among neonates with AKI, the odds of needing PD was significantly higher among those with significant cardiac disease (odds ratio (95% confidence interval): 4.95 (2.39-10.27); p < 0.001), inotropes usage (4.77 (1.98-11.51); p < 0.001), severe peripartum event (4.37 (1.31-14.57); p = 0.02), requirement of respiratory support in NICU (4.17 (1.00-17.59); p = 0.04), necrotising enterocolitis (3.96 (1.21-13.02); p = 0.03), any grade of intraventricular haemorrhage (3.71 (1.63-8.45); p = 0.001), evidence of fluid overload during the first 12 h in NICU (3.69 (1.27-10.70); p = 0.02) and requirement of resuscitation in the delivery room (2.72 (1.45-5.12); p = 0.001). AKI neonates with PD as compared to those without PD had a significantly lower median (interquartile range) duration of stay in NICU (7 (4-14) vs. 11 (6-21) days; p = 0.004), but significantly higher mortality (31 (70.5%) vs. 50 (3.2%); p < 0.001). This discrepancy is likely attributable to the critical state of the neonates with AKI. CONCLUSIONS: This is the largest prospective, multicentre study specifically looking at neonatal AKI and need for dialysis in neonates. AKI was seen in 30.7% of neonates (with the need for acute PD in 9% of the AKI group). The odds of needing acute PD were significantly higher among those with significant cardiac disease, inotropes usage, severe peripartum event, requirement of respiratory support in NICU, necrotising enterocolitis, any grade of intraventricular haemorrhage, evidence of fluid overload more than 10% during the first 12 h in NICU and requirement of resuscitation in the delivery room. AKI neonates with PD as compared to AKI neonates without PD had a significantly higher mortality. There is a need to keep a vigilant watch in neonates with risk factors for the development of AKI and need for PD.

OBJECTIVES: To compare the agreement of stool color for triage of infants for phototherapy (STrIP) score and transcutaneous bilirubinometer values with measured serum bilirubin in neonatal hyperbilirubinemia. METHODS: Babies more than 35 weeks of gestation, with clinical jaundice, and on exclusive breastfeeding were included in the study. Babies with who were clinically unstable or who had received phototherapy based on clinical assessment were excluded. The agreement was analyzed using Bland-Altman charts. Results of three non-invasive methods were further compared with the measured serum bilirubin levels. RESULTS: There was a mean difference of 4 mg/dL of bilirubin between transcutaneous bilirubin and serum bilirubin levels, whereas the agreement between the STrIP score and Serum bilirubin shows a difference of only 2 mg/dL. On further analysis of Kramer, transcutaneous and STrIP score, method of bilirubin estimation against serum bilirubin, there was a mean difference 6 mg/dL, 4 mg/dL and 2 mg/dL, respectively. CONCLUSIONS: STrIP score has the best agreement with serum bilirubin in neonates compared to other non-invasive techniques such as transcutaneous bilirubinometry and clinical assessment using Kramer scale.

Background: Acute kidney injury (AKI) is a significant problem in neonates, but the evidence is sparse. Neonatal AKI is an independent risk factor for increased mortality and prolonged hospital stay. There are stark differences in the epidemiology of AKI in neonates amongst the developing and the developed world. Increased prevalence of neonatal sepsis, lack of awareness about neonatal AKI and poor access to pediatric nephrologists add to the improper management of neonatal AKI in the developing countries. Methods: This study is a multicentric, national, prospective cohort study [The Indian iconic Neonatal Kidney Educational Registry (TINKER)] conducted in level 2-3 NICUs in 11 centers across India. We have enrolled nearly 2,000 neonates over the study period. Neonates (≤ 28 days) who were admitted in NICU and those who received intravenous (IV) fluids for at least 48 h for hydration and/or nutrition have been included. Data collection included: (1) baseline demographics (2) daily physiologic and laboratory parameters (3) discharge data. KDIGO workgroup AKI definition modified for neonates was used for defining AKI. Data entry was carried out by individual participating centers using a web-based database (akiregistry.org). De-identified data has been maintained and handled by the principal investigator (PI). This collaboration plans to disseminate data through peer-reviewed publications and through presentations at educational conferences. Conclusions: The purpose of this study is to create the first prospective neonatal all-cause AKI data repository and describe the incidence of neonatal AKI in NICUs in the country and determine the risk factors as well as the outcomes of such neonates-both short-term and long-term outcomes. This will eventually spur therapeutic advancements, facilitate decipherment of epidemiological trends, risk factors as well as outcomes and identify disparities in management across the nation.
RESUMO
OBJECTIVE: To compare the rate of optimal position of UVC between modified Shukla's formula and JSS formula. METHODS: Babies requiring umbilical vein catheterization were randomized to either Shukla or JSS formula group. Post-procedure X-ray was taken to check the tip position. Tip of the UVC just above the diaphragm (T9 - T10) was considered optimal. Success rate in achieving optimal position between the two groups were compared. RESULTS: Out of 104 babies recruited, 50 were randomized for Shukla's formula and 54 for JSS formula. Catheter tips were in acceptable positions in 39.6% of Shukla group as compared to 56% in JSS group (P=0.02). CONCLUSIONS: The JSS Formula resulted in more optimal placement of UVC than the modified Shukla formula.
