Predictive Ability of Amplitude Integrated Electroencephalography for Adverse Outcomes in Neonates with Sepsis-Associated Encephalopathy: A Cohort Study.

The authors examined the prevalence of abnormal amplitude integrated electroencephalography (aEEG) patterns in neonates diagnosed with sepsis-associated encephalopathy (SAE). They recorded 36626 min of aEEG in 75 study neonates. Encephalopathy was defined by the Brighton Collaboration Neonatal Encephalopathy criteria. Neonates with primary outcome [either non-survivors or survivors with abnormal neurological examination at discharge using Amiel-Tison assessment tool, n = 58, (77%)] were compared with 17 survivors having normal neurological examination at discharge. Severely abnormal aEEG patterns (isoelectric voltage, continuous low voltage, burst suppression) collectively represented 31% of total 36626 min aEEG tracings. Neonates experiencing primary outcome had significantly higher Burdjalov scores than survivors with normal neurological exam (p value 0.01). After adjusting for gestational age, birth weight, and invasive ventilation, severely abnormal aEEG (aOR 5.8, 95% CI 1.7-19.5, p value 0.005) and Burdjalov score (aOR 0.77, 95% CI 0.63-0.95, p value 0.01) were independently associated with death or abnormal neurological examination at discharge.

Periodic Rotation versus Continuous Application of Same Nasal Interface for Non-invasive Respiratory Support in Preterm Neonates: A Systematic Review and Meta-analysis.

OBJECTIVES: To review whether the periodic rotation of nasal mask with binasal prongs is superior to continuous application of either of the interfaces in preterm infants on non-invasive positive pressure respiratory support. METHOD: The authors searched Medline, CINAHL, Embase, Web of Science, and CENTRAL for randomized controlled trials (RCTs) comparing periodic rotation of the two interfaces (mask or prongs) against the continuous application of either, in preterm infants on nasal continuous positive airway pressure (nCPAP) or nasal intermittent positive pressure ventilation (NIPPV). They performed a random-effects meta-analysis using RevMan 5.4. The primary outcome was the incidence of moderate to severe nasal injury. Other outcomes included any nasal injury, need for invasive ventilation, duration of respiratory support, hospital stay, and mortality. RESULTS: Four RCTs (520 participants) were included. There was no difference in the incidence of moderate to severe nasal injury between periodic rotation vs. continuous nasal mask (3 RCTs, 293 participants; RR: 1.75, 95% CI: 0.73-4.19), or periodic rotation vs. continuous binasal prongs (3 RCTs, 296 participants; RR: 0.40, 95% CI: 0.14-1.11). Periodic rotation lowered the incidence of any grade nasal injury compared to continuous binasal prongs (RR: 0.61, 95% CI: 0.49-0.75) but not compared to continuous nasal mask (RR: 1.38, 95% CI: 0.92-2.06). Periodic rotation was associated with longer non-invasive respiratory support (compared to prongs) and prolonged hospital stay (compared to masks). There were no significant differences in other clinical outcomes. CONCLUSIONS: Among preterm infants receiving non-invasive respiratory support, periodically rotating a nasal mask with short binasal prongs may not be superior to the continuous application of nasal masks.

Antimicrobial Resistance Patterns Among Neonates Referred to Pediatric Emergency in North India: A Prospective Cohort Study.

BACKGROUND: Sepsis is a leading cause of neonatal mortality worldwide, with a disproportionately high burden in low-income and middle-income countries. There is limited prospective data on microorganism profiles and antimicrobial resistance (AMR) in outborn newborns referred to pediatric emergency in developing countries. We aimed to assess the pathogen profile and AMR patterns in outborn neonates referred to the pediatric emergency at a tertiary care center. METHODS: In this prospective cohort study, we enrolled neonates with suspected sepsis and sent blood or cerebrospinal fluid cultures. Neonates were followed up daily until discharge or death. The isolated organisms were identified and tested for antimicrobial susceptibility. Standard definitions were used to define multidrug resistance. RESULTS: Between January 1, 2020, and December 31, 2020, 1072 outborn neonates with suspected sepsis were enrolled. The rate of proven sepsis was 223.6 (95% CI:198.7-248.4) per 1000 infants. Gram-negative sepsis was the most common (n = 107,10%), followed by gram-positive sepsis (n = 81,7.6%) and fungal sepsis (n = 67,6.3%). Coagulase-negative staphylococci (n = 69), Candida spp. (n = 68), Klebsiella spp. (n = 55), Acinetobacter spp . (n = 31) and Escherichia coli (n = 9) were the most common pathogens. Over two-thirds (68.6%) of pathogens were multidrug resistance, with an alarming prevalence in Klebsiella spp. (33/53, 62%), Acinetobacter spp. (25/30, 83%) and coagulase-negative staphylococci (54/66, 82%). In total, 124 (11.6%) neonates died in the hospital (13.3% of proven cases and 11.1% of culture-negative sepsis cases). CONCLUSIONS: High sepsis burden and alarming AMR among neonates referred to tertiary care centers warrant urgent attention toward coordinated implementation of rigorous sepsis prevention measures and antimicrobial stewardship across all healthcare levels.

Overwhelming orbital cellulitis in a neonate.

This article discusses a rare ophthalmic manifestation of neonatal bacterial infection and its management, including surgical drainage. The case discussed is that of a neonate who presented with rapidly progressing ophthalmic symptoms suggestive of orbital cellulitis. The neonate also had extensive intracranial involvement and had spread to contiguous structures causing a temporal lobe abscess. As there was no local injury, a haematogenous spread was strongly considered. With blood culture and pus culture yielding the growth of Staphylococcus aureus, systemic antibiotics and surgical interventions were required to successfully manage the neonate. Through this case report, we emphasise that orbital infections are grave in neonates and may culminate into devastating intracranial complications; hence, it necessitates appropriate medical and surgical interventions right from hospital admission.

Role of perfusion index and plethysmography variability index for predicting outcomes in neonatal sepsis.

AIM: (i) To compare perfusion index (PI) and plethysmography variability index (PVI) between neonates with proven or probable sepsis versus no-sepsis, (ii) to examine an association of PI and PVI with in-hospital mortality. METHODS: We enrolled neonates with clinically presumed sepsis. Culture-proven or probable sepsis were categorised as 'cases' and no-sepsis as 'controls'. PI and PVI were recorded hourly for 120 h and averaged in 20-time epochs (0-6 h to 115-120 h). RESULTS: We analysed 148 neonates with sepsis (proven sepsis = 77, probable sepsis = 71) and 126 with no-sepsis. Neonates with proven/probable sepsis and no-sepsis had comparable PI and PVI values. Among 148 neonates with sepsis, 43 (29%) died. Non-survivors had significantly lower PI values than survivors (mean difference 0.21 [95% CI 0.14-0.29], p-value <0.001). PI had a significant but modest discriminative ability to identify non-survivors. However, PI did not independently predict mortality. CONCLUSION: Neonates with proven/probable sepsis and no-sepsis had comparable PI and PVI values in the first 120 h of sepsis. PI but not PVI values were significantly lower in non-survivors than survivors. PI did not independently predict in-hospital mortality. Due to modest discriminative ability, PI should be interpreted along with other vital signs to take clinical decisions.

Early Blood Pressure Changes in Neonatal Sepsis and the Risk of Mortality.

OBJECTIVES: To compare blood pressures (BP) between neonates with culture-proven sepsis and clinical sepsis in the first 120 h of sepsis onset and to examine association between BP and in-hospital mortality. METHODS: In this cohort study, consecutively enrolled neonates with 'culture-proven' sepsis [growth in blood/ cerebrospinal fluid (CSF) within 48 h] and clinical sepsis (sepsis workup negative, cultures sterile) were analyzed. Their BP was recorded every 3-hourly for initial 120 h and averaged in 20 time-epochs of 6 h each (0-6 h to 115-120 h). BP Z-scores were compared between neonates with culture-proven vs. clinical sepsis and survivors vs. non-survivors. RESULTS: Two hundred twenty eight neonates (102-culture-proven and 126-clinical sepsis) were enrolled. Both groups had comparable BP Z-scores except significantly lower diastolic BP (DBP) and mean BP (MBP) in 0-6 and 13-18 time-epochs in culture-proven sepsis group. Fifty-four neonates (24%) died during their hospital stay. BP Z-scores in the initial 54 h of sepsis were independently associated with mortality [systolic BP (SBP) Z-scores in first 54 h, DBP Z-scores in first 24 h, and MBP Z-scores in first 24 h] after adjusting for gestational age, birth weight, cesarean delivery, and 5-min Apgar score. On receiver operating characteristic curves, SBP Z-scores showed better discriminative ability than DBP and MBP to identify non-survivors. CONCLUSIONS: Neonates with culture-proven and clinical sepsis had comparable BP Z-scores except low DBP and MBP in the initial few hours in culture-proven sepsis. BP in initial 54 h of sepsis was significantly associated with in-hospital mortality. SBP discriminated non-survivors better than DBP and MBP.

Room air versus 100% oxygen for delivery room resuscitation of preterm neonates in low resource settings: A randomised, blinded, controlled trial.

AIM: International Liaison Committee on Resuscitation (ILCOR-2020) report recommend starting delivery room resuscitation of all preterm neonates of <35 weeks' gestation with 21-30% oxygen. However, the correct initial oxygen concentration for resuscitation of preterm neonates in delivery room is inconclusive. In this blinded, randomised, controlled trial, we compared room air with 100% oxygen for oxidative stress and clinical outcomes in delivery room resuscitation of preterm neonates. METHODS: Preterm neonates 28-33 weeks' gestation requiring positive pressure ventilation at birth were randomly allocated to room air or 100% oxygen. Investigators, outcome assessors and data analysts were blinded. Rescue 100% oxygen was used whenever trial gas failed (need for positive pressure ventilation >60 s or chest compression). PRIMARY OUTCOME: Plasma 8-isoprostane levels at 4 h of age. SECONDARY OUTCOMES: mortality by discharge, bronchopulmonary dysplasia, retinopathy of prematurity and neurological status at 40 weeks post-menstrual age. All subjects were followed till discharge. Intention to treat analysis was carried out. RESULTS: A total of 124 neonates were randomised to room air (n = 59) or 100% oxygen (n = 65). Isoprostane level at 4 h was similar in both the groups (median (interquartile range): 280 (180-430) vs. 250 (173-360) pg/mL, P = 0.47). No difference was observed in mortality and other clinical outcomes. Room air group had higher treatment failures (27 (46%) vs. 16 (25%); relative risk (RR) 1.9 (1.1-3.1)) and took longer time to establish regular respiration (230 ± 231 vs. 182 ± 261, mean difference = 48 (40, 136) seconds). CONCLUSIONS: In preterm neonates 28-33 weeks' gestation requiring resuscitation in the delivery room, room air (21%) is not the correct concentration to initiate resuscitation. Larger controlled trials involving multiple centres in low- and middle-income countries are immediately required for a conclusive answer.

To feed or not to feed during therapeutic hypothermia in asphyxiated neonates: a systematic review and meta-analysis.

The practice of withholding feed during therapeutic hypothermia (TH) in neonates with hypoxemic ischemic encephalopathy (HIE) is based on conventions rather than evidence. Recent studies suggest that enteral feeding might be safe during TH. We systematically compared the benefits and harms of enteral feeding in infants undergoing TH for HIE. We searched electronic databases and trial registries (MEDLINE, CINAHL, Embase, Web of Science, and CENTRAL) until December 15, 2022, for studies comparing enteral feeding and non-feeding strategies. We performed a random-effects meta-analysis using RevMan 5.4 software. The primary outcome was the incidence of stage II/III necrotizing enterocolitis (NEC). Other outcomes included the incidence of any stage NEC, mortality, sepsis, feed intolerance, time to full enteral feeds, and hospital stay. Six studies ((two randomized controlled trials (RCTs) and four nonrandomized studies of intervention (NRSIs)) enrolling 3693 participants were included. The overall incidence of stage II/III NEC was very low (0.6%). There was no significant difference in the incidence of stage II/III NEC in RCTs (2 trials, 192 participants; RR, 1.20; 95% CI: 0.53 to 2.71, I2, 0%) and NRSIs (3 studies, no events in either group). In the NRSIs, infants in the enteral feeding group had significantly lower sepsis rates (four studies, 3500 participants, RR, 0.59; 95% CI: 0.51 to 0.67, I2-0%) and lower all-cause mortality (three studies, 3465 participants, RR: 0.43; 95% CI: 0.33 to 0.57, I2-0%) than the infants in the "no feeding" group. However, no significant difference in mortality was observed in RCTs (RR: 0.70; 95% CI: 0.28 to 1.74, I2-0%). Infants in the enteral feeding group achieved full enteral feeding earlier, had higher breastfeeding rates at discharge, received parenteral nutrition for a shorter duration, and had shorter hospital stays than the control group.  Conclusion: In late preterm and term infants with HIE, enteral feeding appears safe and feasible during the cooling phase of TH. However, there is insufficient evidence to guide the timing of initiation, volume, and feed advancement. What is Known: • Many neonatal units withhold enteral feeding during therapeutic hypothermia, fearing an increased risk of complications (feed intolerance and necrotizing enterocolitis). • The overall risk of necrotizing enterocolitis in late-preterm and term infants is extremely low (< 1%). What is New: • Enteral feeding during therapeutic hypothermia is safe and does not increase the risk of necrotizing enterocolitis, hypoglycemia, or feed intolerance. It may reduce the incidence of sepsis and all-cause mortality until discharge.

Meningitis Among Neonates with Suspected Sepsis Presenting to Pediatric Emergency.

We aimed to assess the risk factors, clinical features and microbial profiles of meningitis in neonates with suspected sepsis referred to a pediatric emergency. Over 13 months, 191 neonates were enrolled, of whom 64 (33.5%) had meningitis. There were no significant differences in risk factors or clinical features between infants with and without meningitis. Ninety-three neonates (49%) had culture-positive sepsis (109 isolates). Candida spp. (n = 29), coagulase-negative staphylococci (n = 28) and Klebsiella pneumoniae (n = 23) were the most common pathogens. Forty-one (53%) bacteria were multidrug resistant.

Oxygen saturation centiles in healthy preterm neonates in the first 10 min of life: a prospective observational study.

Current oxygen saturation targets in delivery room given by Neonatal Resuscitation Program (NRP) are essentially derived from term neonates. This prospective observational study was conducted in a level-III neonatal unit in preterm neonates (< 37 weeks) who did not receive resuscitation or supplemental oxygen to create centile charts for pre-ductal oxygen saturations using robust statistical modelling methods. Pre-ductal oxygen saturations (SPO2) were recorded from birth till 10 min of age using current generation Masimo pulse oximeters. Centile charts were created by generalized additive models. The change in oxygen saturations over time across subjects was modelled as a Bayesian linear regression mixed-effects model after including 'a priori' covariates. Oxygen saturation data was analysed in 180 subjects with mean gestation of 34 ± 2 weeks. Mean (SD) time to first SPO2 was 167 ± 77 s. The median time to SPO2 of > 90% was 310 s (IQR: 235-400). Time to > 90% SPO2 was shorter in (a) 34-36 weeks compared to < 34 weeks (290 vs 340; p = 0.03) and (b) vaginally delivered compared to caesarean-section born neonates (300 vs 360; p = 0.2).    Conclusions: Oxygen saturations in first 10 min of age in healthy preterm neonates are significantly higher than the targets proposed by the NRP-2020. Larger preterm neonates and those born through vaginal route attained a preductal saturation of > 90% sooner. What is Known: • Pulse oximetry is the standard for oxygen saturation monitoring during immediate postnatal period. • Healthy term neonates take many minutes after birth to reach a pre-ductal saturation of >90%. But, postnatal oxygen saturation trend data in healthy preterm neonates are scarce. What is New: • Provides centile charts for oxygen saturations till 10 minutes of age using current generation Masimo pulse oximeters in a large cohort of healthy preterm neonates using robust statistical modelling methods. • Identifies covariates that significantly modifies the saturation trends using a Bayesian mixed models' regression.

Change in Score for Neonatal Acute Physiology-II Measurements for Prediction of Mortality in Severely Septic Preterm Neonates.

OBJECTIVE: To study the discriminatory ability of the change (delta) in the Score for Neonatal Acute Physiology-II (SNAP-II) for 14-d mortality in preterm neonates with severe sepsis. METHODS: Consecutively born neonates of < 34-wk gestation during the 1-y study period in a tertiary care neonatal unit were included. SNAP-II was recorded at the onset of severe sepsis (T0) and serially at 24 (T1), 48 (T2), and 72 (T3) h. Delta scores (Δ SNAP-II) were derived from the difference between the SNAP-II at baseline and each one of the subsequent time points. RESULTS: Seventy-one preterm neonates were enrolled. Baseline characteristics were similar in survivors (n = 53) and nonsurvivors (n = 18). Median SNAP-II at all the four time points were significantly higher in nonsurvivors (p < 0.001). Delta SNAP-II (T0-T2) was significantly different between nonsurvivors and survivors (mean difference: -14.7; 95% CI: -29, -0.9; p = 0.02), while the difference was not significant between T0-T1 and T0-T3. Initial SNAP-II had a significantly better discriminating ability than Δ SNAP-II at various time points (AUC, 95% CI: 0.59, 0.41-0.75 for T0-T1; 0.70, 0.50-0.87 for T0-T2; and 0.64; 0.38-0.89 for T0-T3). CONCLUSIONS: Delta SNAP-II does not have a better discriminatory ability for mortality by 14 d in preterm neonates with severe sepsis.

NETwork Meta-analysis Of Trials of Initial Oxygen in preterm Newborns (NETMOTION): A Protocol for Systematic Review and Individual Participant Data Network Meta-Analysis of Preterm Infants <32 Weeks' Gestation Randomized to Initial Oxygen Concentration for Resuscitation.

BACKGROUND: Internationally recognized guidelines recommend the judicious use of low oxygen (21-30%), titrated to peripheral oxygen saturation targets, for the initiation of resuscitation of very and extremely preterm infants (<32 weeks' gestation). However, despite more than 10 randomized controlled trials on this question, the ideal initial oxygen concentration for this group of vulnerable infants remains uncertain. AIMS: This study aims to assess the effect of various initial oxygen concentrations on (1) all-cause mortality, chronic lung disease, intraventricular hemorrhage, and retinopathy of prematurity; and (2) reaching the prescribed oxygen saturation targets by 5 min after birth, in preterm infants requiring resuscitation. METHODS: We will conduct a systematic review and network meta-analysis using individual participant data. Studies of preterm infants <32 weeks' gestation, randomized to initial oxygen concentration, will be included. We will systematically search medical databases and trial registries for eligible studies (published or unpublished). Records will be screened by two independent reviewers, with conflicts resolved by the inclusion of a third reviewer. Identified initial oxygen concentrations will be grouped into the following nodes: low (≤30%), intermediate (60%), and high (≥90%) oxygen. A two-step random-effects contrast-based network meta-regression will be calculated to compare and rank different oxygen concentrations. Analyses will be intention-to-treat, with the primary outcome of all-cause mortality. DISCUSSION: This is the first individual participant data network meta-analysis of initial oxygen concentrations for the resuscitation of preterm infants. This novel approach may address long-standing uncertainty regarding optimal oxygen supplementation practice for the resuscitation of preterm infants <32 weeks' gestation.

Clinical characteristics & outcome of SARS-CoV-2 infected neonates presenting to paediatric emergency.

Background & objectives: Data on neonatal COVID-19 are limited to the immediate postnatal period, with a primary focus on vertical transmission in inborn infants. This study was aimed to assess the characteristics and outcome of COVID-19 in outborn neonates. Methods: All neonates admitted to the paediatric emergency from August 1 to December 31, 2020, were included in the study. SARS-CoV-2 reverse transcription- (RT)-PCR test was done on oro/nasopharyngeal specimens obtained at admission. The clinical characteristics and outcomes of SARS-CoV-2 positive and negative neonates were compared and the diagnostic accuracy of a selective testing policy was assessed. Results: A total of 1225 neonates were admitted during the study period, of whom SARS-CoV-2 RT-PCR was performed in 969. The RT-PCR test was positive in 17 (1.8%). Mean (standard deviation) gestation and birth weight of SARS-CoV-2-infected neonates were 35.5 (3.2) wk and 2274 (695) g, respectively. Most neonates (11/17) with confirmed COVID-19 reported in the first two weeks of life. Respiratory distress (14/17) was the predominant manifestation. Five (5/17, 29.4%) SARS-CoV-2 infected neonates died. Neonates with COVID-19 were at a higher risk for all-cause mortality [odds ratio (OR): 3.1; 95% confidence interval (CI): 1.1-8.9, P=0.03]; however, mortality did not differ after adjusting for lethal malformation (OR: 2.4; 95% CI: 0.7-8.7). Sensitivity, specificity, accuracy, positive and negative likelihood ratios (95% CI) of selective testing policy for SARS-CoV-2 infection at admission was 52.9 (28.5-76.1), 83.3 (80.7-85.6), 82.8 (80.3-85.1), 3.17 (1.98-5.07), and 0.56 (0.34-0.93) per cent, respectively. Interpretation & conclusions: SARS-CoV-2 positivity rate among the outborn neonates reporting to the paediatric emergency and tested for COVID-19 was observed to be low. The selective testing policy had poor diagnostic accuracy in distinguishing COVID-19 from non-COVID illness.

Congenital Rubella Syndrome as a possible cause for persistent thrombocytopenia in early infancy: The Forgotten Culprit.

We present a case of a late preterm intrauterine growth-restricted neonate with isolated and persistent severe thrombocytopenia. At birth, the neonate did not have a complete clinical spectrum of congenital rubella syndrome (CRS) but later developed peculiar findings that helped clinch the diagnosis. The neonate also had interstitial pneumonia and died secondary to superimposed acute viral infection leading to acute respiratory distress syndrome. The serology was positive for IgM antibodies against the rubella virus. The constellation of clinical manifestations of congenital rubella in the presence of positive IgM antibody against rubella and consistent histopathology confirmed the diagnosis of CRS.

Hand Hygiene Compliance in Pediatric Emergency of a Lower-Middle Income Country: A Quality Improvement Study.

Background: Prospective data on hand hygiene compliance in pediatric emergency department (PED) settings is limited. We studied the impact of quality improvement measures on the overall and health care personnel wise hand hygiene compliance rates in a busy PED. Methods: The baseline hand hygiene compliance rates were audited from May-July 2018. The quality improvement interventions included various structural changes to the environment, administrative changes, education and training. During the interventions, auditing was continued for 2 months (August - September 2018). Statistical Process control charts were created. Results: We observed a significant increase in overall compliance rates from 31.8 to 53.9% (p < 0.001). These improvements were observed in the children (29.6 to 46.4%, p < 0.001) as well as neonatal area (35.7% to 59.7, p < 0.001) of PED as well as amongst various health care personnel and in four out of the five moments of hand hygiene. Conclusion: Hand hygiene compliance improved significantly in a busy PED of a lower middle-income country following quality improvement interventions. Such improvement was observed amongst all categories of health care personnel and different types of hand hygiene opportunities. This study demonstrates the feasibility and efficacy of simple quality improvement interventions in a challenging hospital environment.

Relationship between Decrease in Urine Output following Treatment with Prostaglandin Inhibitors and PDA Closure.

OBJECTIVE: Prostaglandin inhibitors are used for the treatment of patent ductus arteriosus (PDA) and they often transiently decrease the urine output (UO) due to prostaglandin inhibition in the renal vasculature. We hypothesized that preterm infants whose renal vasculature shows greater sensitivity to prostaglandin inhibitors are likely to have ductal tissue with greater sensitivity to the same. Our objective was to determine whether the decrease in UO following treatment of PDA with a prostaglandin inhibitor is associated with a higher probability of PDA closure. STUDY DESIGN: In a prospective, proof-of-concept, cohort study, we enrolled 40 preterm neonates with hemodynamically significant PDA (hsPDA), being treated with a prostaglandin inhibitor. The key predictor, UO, was measured at baseline and daily until 72 hours. We repeated echocardiography daily until PDA closure or the end of treatment. The key outcome was PDA closure. We compared "PDA-closed" (n = 28) and "PDA-open" (n = 12) groups for change in UO from baseline. RESULTS: The median (Q1, Q3) percent decrease in UO (figures rounded off to integers) was greater in the "PDA-closed" versus "PDA-open" group: from baseline to 0 to 24 hours [-45% (-55%, +0.04%) vs. -15% (-28%, +49%)]; baseline to 24 to 48 hours [-41% (-53%, +14%) vs. -3% (-25%, +62%), p = 0.03] and baseline to 48 to 72 hours [-33% (-49%, +32%) vs. +21% (-7%, +98%), p = 0.02]. Decrease in UO preceded PDA closure. The "PDA-closed" group had significantly greater weight loss, despite a greater decrease in UO. A decrease in UO of 27 and 17% by 24 to 48 hours and 48 to 72 hours, respectively, best predicted PDA closure. CONCLUSION: A decrease in UO after treating hsPDA with a prostaglandin inhibitor is associated with successful closure of PDA. KEY POINTS: · Prostaglandin inhibition causes both decrease in urine output and PDA closure following medical treatment. · The association between drug-induced decrease in urine output and PDA closure has been inadequately studied.. · Decrease in urine output after treatment with prostaglandin inhibitors increases the chances of PDA closure..

Relationship Between COVID-19 Lockdown and Epidemiology of Neonatal Sepsis.

BACKGROUND: We compared the hospital-based epidemiology of neonatal sepsis after the coronavirus disease 2019 lockdown (LD) versus historical epochs and the LD period versus phases of unlocking. METHODS: This retrospective cohort study was conducted in a level 3 neonatal unit. We compared neonates born in three 24-week periods-Group LD: 22 March 2020 to 5 September 2020-the reference group, Group pre-LD: 29 September 2019 to 14 March 2020 and Group temporally corresponding to LD in 2019 (corres-LD): 24 March 2019 to 7 September 2019. We also studied linear trends from LD phase 1.0 until Unlock 4.0. The key outcome was culture-positive sepsis. RESULTS: There were 1622, 2744 and 2700 subjects in groups LD, pre-LD and corres-LD, respectively. The incidence of any culture-positive sepsis in pre-LD was higher than LD [odds ratio (95% CI) = 1.61 (1.02-2.56)]. This was mainly due to a statistically significant reduction in Acinetobacter baumannii sepsis, with incidence rate differences of pre-LD versus LD [0.67 (95% CI: 0.37-0.97), P = 0.0001] and corres-LD versus LD [0.40 (95% CI: 0.16-0.64), P = 0.0024]. Groups pre-LD and corres-LD had higher proportion of multi-drug resistant (MDR)/extreme drug resistance/pan drug resistance sepsis than LD [77%, 77% and 44%, respectively (P values of both groups vs. LD = 0.01)]. From LD 1.0 to unlock 4.0, there were fewer episodes of MDR sepsis (Plinear trends = 0.047). On multivariable analysis, group pre-LD (vs. reference group LD), male sex, birth weight and Apgar score independently predicted culture-positive sepsis. CONCLUSIONS: LD favorably impacted the epidemiology of neonatal sepsis in a hospital setting, with less A. baumannii and MDR sepsis, which persisted during unlocking.

Clinical Presentation, Investigation and Control of an Outbreak of Adenoviral Conjunctivitis in a Neonatal Unit at a Tertiary Hospital.

BACKGROUND: Nosocomial spread of adenovirus infection has been reported in neonatal, pediatric and adult medical units. This nonenveloped and hardy virus is resistant to numerous disinfectants thus posing a challenge for control and prevention of adenovirus infections in health care settings. METHODS: An epidemiologic outbreak investigation revealed an adenoviral outbreak in the neonatal nursery as well as in the neonatal screening outpatient department for Retinopathy of Prematurity (ROP). All suspected cases (94 neonates) underwent adenoviral conventional polymerase chain reaction (PCR) and representative samples underwent sequencing by Sanger's method. The clinical features and disease course were studied. Infected babies were started on tobramycin eye drops. Topical steroid eye drops were added for those who developed pseudomembranes. RESULTS: We found 58 cases of laboratory-confirmed neonatal adenovirus conjunctivitis (between July 10 and October 24, 2019). Redness (96%) was the most common presentation followed by discharge (68.9%) and lid edema (51.7%). Pseudomembrane were seen in 77.5% of the infected neonates. Prior ROP examination was carried out in 38 (65.5%) neonates. Respiratory symptoms were present in 7 (12.06%) neonates. Sequencing revealed serotype 8 as the cause of the outbreak. Control measures were strictly implemented. Standard Operating Procedures (SOPs) for ROP screening were revisited, revised and reinforced to prevent future outbreaks. CONCLUSIONS: We observed ROP screening as a risk factor for the development of adenoviral conjunctivitis in neonatal care units. Neonates present with different clinical manifestations as compared with adults. Prompt control measures were implemented to control the adenoviral outbreak.
