Pharmacovigilance of nephrotoxic drugs in neonates: the Pottel method for acute kidney injury detection in ELBW neonates

BackgroundExtremely low birth weight (ELBW) neonates (birth weight ≤ 1000 g) are at high risk to develop drug-induced acute kidney injury (AKI). However, we lack a pragmatic detection tool to capture their time-dependent (patho)physiologic serum creatinine (Scr) patterns. Pottel et al. suggested rescaling Scr by dividing Scr with the mean Scr value of the age- and sex-specific reference population. We explored if this Pottel method can detect drug-related nephrotoxicity in ELBW neonates.MethodsA previously reported dataset on Scr changes in ELBW neonates exposed to ibuprofen, amikacin, or vancomycin was updated to calculate Pottel scores for every available Scr value in the first 28 postnatal days. We hereby used previously published postnatal age-specific 50th centile values in an ELBW population. Linear mixed models were applied, analyzing Pottel scores as response variable and continuous time (day), drug exposure, and interaction thereof in the explanatory model.ResultsSerum creatinine (n = 3231) observations in 201 ELBW neonates were collected. A statistically significant rise of Pottel scores was observed with ibuprofen starting from postnatal day 4. In addition, a cumulative effect of treatment with mean Pottel scores on day 0 of 1.020 and on day 3 during treatment of 1.106 (95% CI 1.068–1.145, p < 0.001) was observed, corrected for effect of antibiotics. Antibiotic administrations showed a small but statistically significant difference up to postnatal day 5.ConclusionsAs rescaled Scr biomarker, the Pottel method showed a clear association with ibuprofen-exposed ELBW neonates, suggesting its applicability as a pragmatic bedside alternative tool to assess nephrotoxicity.Graphical abstractA higher resolution version of the Graphical abstract is available as Supplementary information

Clinical Outcomes of Slow versus Rapid Enteral Feeding Advancement in Very Low Birth Weight Neonates at a Tertiary Care Center

In India, every year around 3.5 million babies are born premature, accounting for almost 13% of total livebirths in the country as compared to 5% to 7% incidence in the West. Preterm is defined as babies born before 37 weeks ofpregnancy. The rapidity of feed volume increments involves controversies like faster weight gain, shorter hospital stays, therisk of necrotizing enterocolitis and vice versa. Methods: The present study was a randomized controlled trial conducted fromJune 1, 2018 to October 31, 2019. All infants in the study were randomized to slow and rapid feeding protocols by a stratifiedblock randomization sequence of 2, 4, 6 blocks. Group 1 or the slow advancement group included 64 newborns babies andGroup 2 or the rapid advancement group included 69 newborns babies. Results: The average weight gain in Group 1 was4.41 ± 0.9 g and in Group 2 it was 6.33 ± 1.3 g, the difference was statistically significant (p &lt; 0.02). Sixty out of 64 newbornsregained birth weight within 16.87 ± 0.9 days in Group 1, while 64 out of 69 newborns regained birth weight within 13.63 ±0.9 days in Group 2. The difference was statistically significant. Increment in the mean occipitofrontal circumference perweek was 0.29 ± 0.27 cm Group 1, while in Group 2 it was 0.42 ± 0.05 cm; the difference was statistically significant. Meanaverage length increment per week was found to be 0.55 ± 0.04 cm and 0.69 ± 0.05 cm in Group 1 and Group 2, respectively,the difference was statistically significant (p &lt; 0.005). The mean duration of hospital stay was 27.47 ± 3.33 days in Group 1while in Group 2, the duration of stay was 23.15 ± 2.22 days, the difference was statistically significant. Conclusion: Ourstudy supports enteral nutrition by rapid enteral feeding regimen in stable preterm neonates with very low birth weight

Abstract P296: The Association Between Maternal Occupation and Adverse Birth Outcomes Among Infants With Congenital Heart Defects

Background: Neonates with critical congenital heart defects (cCHDs) face increased risks of neonatal complications, including low birth weight (LBW) and preterm birth (PTB). Maternal occupation has known associations with adverse birth outcomes in the general population. We aimed to assess the link between maternal occupation and adverse birth outcomes in neonates with cCHDs. Methods: We examined Texas Birth Defects Registry (TBDR) data from 1999-2014, focusing on employed mothers of non-syndromic live born singletons with cCHD. Using the NIOSH Industry and Occupation Computerized Coding System (NIOCCS) and manual coding, we categorized maternal occupation into 23 major groups. Neonates with cCHDs and adverse birth outcomes were compared to neonates with cCHDs without adverse outcomes. Logistic regression models assessed the association between maternal occupation and PTB and LBW, with the reference group being all other occupations. Results: There were 712 mothers with preterm neonates with cCHDs and 3,076 mothers with full-term neonates with cCHDs. Additionally, 776 mothers delivered LBW neonates, while 3,012 had normal birthweight neonates. Maternal occupations in computer/math science were negatively linked to PTB (OR: 0.29; 95% CI: 0.10-0.79) and LBW (OR: 0.26; 95% CI: 0.09-0.70). Food preparation occupations were positively associated with PTB (OR: 1.67; 95% CI: 1.17-2.38), while arts/entertainment occupations were negatively associated with LBW (OR: 0.30; 95% CI: 0.11-0.84). Conclusion: These findings align with previous reports, suggesting that mothers in certain occupations may engage in behaviors linked to adverse pregnancy outcomes in the general population, such as insufficient folic acid supplementation, delayed prenatal care, smoking, and drinking. Understanding these associations can inform targeted workplace interventions, particularly for pregnancies involving birth defects.

Extremely low birth weight (ELBW) neonates for emergency surgery- A challenge for the Anesthesiologist: A case series

Background: Extremely Low Birth Weight (ELBW) newborns, defined as those with a birth weight of 1000 grams or less, present challenging anesthetic scenarios. Emergency surgeries in these infants elevate their vulnerability to various complications. Case Presentation: We present a case series involving 5 ELBW neonates who underwent emergency surgery. Three of them were at a post-conceptual age (PCA) of ≥ 33 weeks and underwent procedures for congenital birth defects, including esophageal atresia, ileal atresia, and gastroschisis. The remaining two neonates, with a PCA of 29-30 weeks, underwent surgery for necrotizing enterocolitis (NEC). Conclusion: The compromised physiology resulting from distinct disease processes and the underdeveloped systems of ELBW preterm neonates necessitate focused care and strategic anesthesia. This approach is crucial to mitigate morbidity and mortality risks in such vulnerable patients.

Frequency of Intraventricular Haemorrhage (IVH) in Early Preterm Neonates Born at DHQ Teaching Hospital Gujranwala

Objective: The reported frequency of intraventricular hemorrhage in preterm neonates varied greatly. We determined the frequency of IVH in premature neonates in the pediatric unit of DHQ Hospital Gujranwala. Materials &amp; Methods: This cross-sectional study involved 282 very low birth weight neonates (birth weight &lt;1500 gm.) delivered very preterm (gestational age &lt;32 weeks). These neonates were assessed for intraventricular hemorrhage which was diagnosed on cranial ultrasound performed on 3rd day of life. The frequency of IVH was compared across various attributing factors i.e., gestational age at delivery, gender, birth weight, mode of delivery, and maternal antenatal steroids. Results: The mean gestational age at delivery was 27.5±2.3 weeks while the mean birth weight was 1120.5±190.2 grams. 172 (61.0%) neonates were delivered vaginally while C-section was performed in 110 (39.0%) cases. 263 (93.3%) mothers received antenatal steroids. Intraventricular hemorrhage was diagnosed in 64 (22.7%) early preterm neonates. The frequency of IVH increased significantly with increasing prematurity; 24-27 weeks vs. 28-31 weeks (28.9% vs. 17.0%; p-value=0.017), decreasing birth weight; &lt;1 kg vs. ?1kg (31.8% vs. 18.6%; p-value=0.014) and lack of antenatal steroids (52.6% vs. 20.5%; p-value=0.001). Conclusion: The intraventricular hemorrhage was observed in 22.7% of early preterm neonates which advocates routine screening of preterm neonates for IVH so that timely identification and anticipated management may improve the outcome of such neonates. We also identified increasing prematurity, decreasing birth weight, and lack of antenatal steroids as potential attributing factors that can be used for risk stratification and management planning of such cases.

Obstetrical and neonatal outcomes in patients with surgically repaired heart disease

BackgroundCongenital and acquired heart disease complicate 1-4% of pregnancies in the United States. Beyond the risks of the underlying maternal congenital heart disease, cardiac surgery and its sequelae, such as surgical scarring resulting in higher rates of arrhythmias and implanted valves altering anticoagulation status, have potential implications that could affect gestation and delivery. ObjectiveTo investigate whether history of maternal cardiac surgery is associated with adverse obstetrical or neonatal outcomes when compared to patients without a history of cardiac disease or surgery, considered “healthy controls”. Study DesignThis is a secondary analysis of retrospective cohort studies performed at a tertiary care facility in the United States comparing obstetrical outcomes in patients with a history of open cardiac surgery that delivered from January 2007 – December 2018 with healthy controls, that delivered from April 2020-July 2020. There were 74 pregnancies in 61 patients with a history of open cardiac surgery that were compared to pregnancies in healthy controls. Of the 74 pregnancies, 65 were successfully matched based on gestational age to controls at a 1:3 (case:control) ratio. The remainder of cases were matched at a 1:2 or 1:1 ratio; therefore, a total of 219 control pregnancies were included in the analysis. Our primary outcome was the incidence of hypertensive disorders of pregnancy, as well as cesarean section, in patients with a history of open cardiac surgery compared with healthy controls. Our secondary outcome was the incidence of low-birth-weight neonates in patients with a history of open cardiac surgery compared with healthy controls. ResultsPatients with a history of cardiac surgery were not more likely to have any hypertensive disorder diagnosed than healthy controls. Patients with a history of cardiac surgery were more likely to have an operative delivery (p<0.0001) but equally likely to have a cesarean section (p=0.528) when compared with healthy controls. Birthweight was not statistically different of 2655 grams ± 808 grams in neonates born to patients with a history of cardiac surgery vs. 2844 grams ± 830 grams born to healthy controls (p=.092). ConclusionsPatients with a history of cardiac surgery may not be at higher risk of hypertensive disorder diagnosis during pregnancy. Similarly, most patients with a history of cardiac surgery are also likely not at higher risk for cesarean section or low birthweight neonates.

Profile of metabolic bone disease in extremely low birth weight (ELBW) and very low birth weight (VLBW) neonates

BackgroundMetabolic bone disease (MBD) is an important cause of morbidity in premature, very low birth weight (VLBW), and sick infants and, if left undiagnosed, may lead to structural deformities and spontaneous fractures. The objective of the present study was to study the profile of MBD and to determine the incidence of MBD in infants ≤ 32 weeks/≤ 1250 g at birth.MethodA total of 57 infants ≤ 32 weeks/≤ 1250 g at birth admitted in our NICU from October 2020 to July 2021 were included in the study. These infants underwent screening for MBD at 4 weeks of age. They were stratified into three groups based on their gestation (≤ 28 weeks, 29–30 weeks, 31–32 weeks).ResultsMBD was observed in 100% of extreme preterm babies and 69% of very preterm babies. Overall, the incidence of MBD was 73%. Serum phosphorus level normalized by 42–44 weeks post menstrual age (PMA) across all gestations. Alkaline phosphatase (ALP) levels normalized by 42–44 weeks only in very preterm babies. Seventeen babies ≤ 30 weeks required inorganic phosphorus supplementation in addition to calcium phosphate supplementation in order to correct the MBD. Drugs like caffeine, steroids, and furosemide have significant impact on the development of MBD. The time to reach full feeds with fortification had no statistically significant effect on the incidence of MBD as detected by serum phosphorus level and serum ALP level.ConclusionThe profile outlined in the present study matches the literature reports in many aspects, revealing the importance of characterizing this group for the prognosis and short- and long-term follow-up of newborns with bone metabolic disease.

Comparison of prematurity-related outcomes and complications in very low birth weight (VLBW) neonates fed with mother`s own milk versus donor milk: a comparative study.

When mother`s own milk (MOM) is unavailable or insufficient, donor milk (DM) from a human milk bank serves as an alternative feeding option. Our study sought to investigate and compare the outcomes and complications of very low birth weight (VLBW) preterm infants who receive MOM versus DM. In this retrospective cohort study conducted between 2018 and 2022, we compared 70 VLBW preterm infants exclusively fed with DM to 70 randomly selected counterparts fed with MOM. Both groups began enteral feeding within 72 hours of birth. Various clinical outcomes were investigated during a three-month follow-up. The clinical outcomes were compared via independent t-tests, Mann-Whitney U, and Fisher`s exact test. The mean gestational age of the infants who were included was 29.6 ± 1.6 weeks, 84 (60%) were males, and the average birth weight was 1217 ± 151 grams. Both groups had similar baseline characteristics. The results of the study demonstrated no statistically significant differences between the groups in terms of hospital length of stay (37±16.3 days in MOM vs 40.3±16.9 days in DM group, P= 0.17), growth rate (13±4 gram/day in MOM vs 13±4 gram/day in DM group, P=0.51), growth velocity (9.8±3.0g/kg/d in MOM vs 9.5±3.2 g/kg/d in DM group), infants with in-hospital vomiting (51 cases in MOM vs 59 cases in DM group, P=0.15),vomiting frequency (1.3±1.1 times in MOM vs 1.5±1.0 times in DM group), incidence of retinopathy of prematurity (ROP) (4 cases in MOM vs 5 cases in DM group, P > 0.999) and incidence of bronchopulmonary dysplasia (BPD) (7 cases in MOM vs 6 cases in DM group, P > 0.999). Our study findings indicate that the utilization of DM didn`t have a substantial negative impact on infants` outcomes nor any complications in comparison with MOM.

A Quality Improvement Initiative To Reduce Invasive Candidiasis In Extremely Low Birth Weight Neonates

Objective: To evaluate the impact of a quality improvement (QI) initiative, which included a Fluconazole prophylaxis protocol and provider education on neonatal Candidiasis. Study Design: Retrospective longitudinal study. Place and Duration of Study: Neonatal Intensive Care Unit (NICU), Aga Khan University, Karachi Pakistan, from Apr 2015 to Dec 2019. Methodology: All extremely low birth weight neonates (ELBW) neonates admitted to the NICU between April 2015 and March 2017 were included in the pre-implementation phase. All ELBW neonates admitted between April 2017 and December 2019 were included in the post-implementation phase. Data were collected from medical records. The primary outcome was the frequency of Invasive Candidiasis (IC) before and after the QI initiative. Results: Altogether, 272 neonates were included in the study, with 115 neonates in the Pre-Implementation Group and 157 neonates in the Post-Implementation Group. The frequency of IC was 6(5.2%) in the pre-implementation and 1(0.6%) in the post-implementation period, (p=0.044). Candida parapsilosis 2(40%) and Candida glabrata 2(40%) were the organisms most commonly isolated from blood cultures. All organisms were sensitive to Fluconazole in both the pre-and post-implementation cohorts. There was no difference in mortality (54(50.5%) vs. 69(44.2%), p=0.32) or length of stay (19.6±13.3 vs. 23.4±18.4 days,p=0.061) before and after Fluconazole prophylaxis. Conclusion: The frequency of invasive Candidiasis in ELBW neonates was successfully reduced by introducing a Fluconazole prophylaxis protocol in the NICU as a QI initiative. A team-based approach and provider education ensured high compliance.

Gestational age, birth weight, and blood culture microbial patterns in late-onset neonatal sepsis

Background The three main causes of neonatal deaths in Indonesia according to the WHO are sepsis, prematurity, and asphyxia. A suboptimal hospital environment increases the risk of late-onset neonatal sepsis (LONS), which in turn can prolong hospital stays.&#x0D; Objective To assess for possible associations of bacterial patterns in neonates with LONS, prematurity, and/or low birth weight.&#x0D; Methods Medical record data of 1,706 hospitalized neonates who were treated for sepsis or other disease in the Neonatal Unit, Dr. Cipto Mangunkusumo Hospital (CMH), Jakarta in 2020 were analyzed retrospectively. A total of 262 neonates had proven LONS. We assessed for possible risk factors such as gestational age, birth weight, and cultured blood microbes.&#x0D; Results Out of a total of 1,706 neonates admitted to the neonatal unit, the incidence of proven LONS was 15.4%. LONS was more prevalent (58.4%) in preterm than in full-term (41.6%) neonates. The majority (67.6%) of subjects with proven LONS were neonates with low birth weight (LBW) (&lt;2,500 grams), and the largest percentage of them (35.1%) was in the 1,500-2,500-gram group. Gram negative bacteria emerged as the predominant pathogens of LONS patients in our hospital; the most common were Klebsiella pneumonia, Acinetobacter spp., Escherichia coli, Enterobacter spp., and Pseudomonas aeruginosa.&#x0D; Conclusion The proportion of LONS among LBW and preterm neonates is significantly higher compared to normal birth weight and neonates. In our unit, LONS was mostly caused by Gram-negative bacteria. The antibiotic susceptibility of the various pathogens causing LONS in CMH should be tested and compared to the current empirical antibiotic guidelines used in CMH.

Effects of hypertensive disorders of pregnancy on the complications in very low birth weight neonates

ABSTRACT Objective This study was designed to investigate the effects of hypertensive disorders of pregnancy (HDP) on the complications in very low birth weight (VLBW) neonates. Methods We retrospectively included VLBW neonates (<37 weeks) who were delivered by HDP pregnant women with a body weight of < 1,500 g (HDP group) hospitalized in our hospital between January 2016 and July 2021. Gestational age matched VLBW neonates delivered by pregnant women with a normal blood pressure, with a proportion of 1:1 to the HDP group in number, served as normal control. Results Then we compared the peripartum data and major complications between HDP group and control. The body weight, prelabor rupture of membrane (PROM), maternal age, cesarean section rate, fetal distress, small for gestational age (SGA), mechanical ventilation, RDS, necrotizing enterocolitis (NEC) (≥2 stage), Apgar score at 1 min, and mortality in HDP group showed statistical differences compared with those of the control (all p < 0.05). To compare the major complications among HDP subgroups, we classified the VLBW neonates of the HDP group into three subgroups including gestational hypertension group (n = 72), pre-eclampsia (PE) group (n = 222), and eclampsia group (n = 14), which showed significant differences in the fetal distress, Apgar score at 1 min, SGA, ventilation, RDS and NEC (≥2 stage) among these subgroups (all p < 0.05). Multivariate regression analysis showed that eclampsia and PE were the independent risk factors for SGA and NEC, respectively. Conclusion HDP was associated with increased incidence of neonatal asphyxia, fatal distress, SGA, mechanical ventilation, RDS, NEC and mortality. Besides, eclampsia and PE were independent risk factors for SGA and NEC.

Survival Status and Predictors of Mortality Among Low-birth-weight Neonates in Southern Ethiopia: A Prospective Follow-up Study

Background: Due to anatomical and physiological immaturity low-birth-weight (LBW) neonates are at risk for different complications which may lead to death at a specified period after birth. Therefore, this study aimed to assess the survival rate and predictors of mortality among LBW neonates. Methods: A hospital-based prospective cohort study design was conducted among 768 LBW neonates. The Cox proportional hazard model was used to identify predictors of mortality among LBW neonates. Result: The mortality rate of low birth weight was 38.8 (95% CI: 33.9–44.3) per 1,000 child-day observations. Parity (AHR = 1.47 [95% CI: 1.06–2.05]), Birth weight &lt;1000 gram (AHR = 4.70 [95% CI: 2.36–9.35]), Birth weight &lt;1500 gram (AHR = 1.62 [95% CI: 1.16–2.27]), Neonatal sepsis (AHR = 2.41 [95% CI: 2.25–2.91]), Birth asphyxia (AHR = 1.46 [95% CI = 1.02–2.08]), Kangaroo mother care (KMC) (AHR = 0.35 [95% CI: 0.24–0.49]), were statistically significantly associated with mortality. Conclusions: The findings of this study revealed that the incidence rate of mortality among LBW neonates was high. Practising KMC for all LBW neonates and appropriate treatment of neonatal sepsis and birth asphyxia were strongly recommended to reduce mortality among LBW neonates.

Predictors of Mortality in Very Low Birth Weight Neonates With Congenital Diaphragmatic Hernia

BackgroundLimited data exists regarding the mortality of very low birth weight (VLBW) neonates with congenital diaphragmatic hernia (CDH). This study aims to quantify and determine predictors of mortality in VLBW neonates with CDH. MethodsThis analysis of 829 U.S. NICUs included VLBW [birth weight ≤1500g] neonates, born 2011–2021 with and without CDH. The primary outcome was in-hospital mortality. A generalized estimating equation regression model determined the adjusted risk ratio (ARR) of mortality. ResultsOf 426,140 VLBW neonates, 535 had CDH. In neonates with CDH, 48.4% had an additional congenital anomaly vs 5.5% without. In-hospital mortality for neonates with CDH was 70.4% vs 12.6% without. Of those with CDH, 73.3% died by day of life 3. Of VLBW neonates with CDH, 38% were repaired. A subgroup analysis was performed on 60% of VLBW neonates who underwent delivery room intubation or mechanical ventilation, as an indicator of active treatment. Mortality in this group was 62.7% for neonates with CDH vs 16.4% without. Higher Apgars at 1 min and repair of CDH were associated with lower mortality (ARR 0.91; 95%CI 0.87,0.96 and ARR 0.28; 0.21,0.39). The presence of additional congenital anomalies was associated with higher mortality (ARR 1.14; 1.01,1.30). ConclusionThese benchmark data reveal that VLBW neonates with CDH have an extremely high mortality. Almost half of the cohort have an additional congenital anomaly which significantly increases the risk of death. This study may be utilized by providers and families to better understand the guarded prognosis of VLBW neonates with CDH. Type of StudyLevel II. Level of EvidenceLevel II.

A randomized control study on the effect of probiotics on feed tolerance in very low birth weight neonates

Background: Probiotics are live microbial supplements that increase feed tolerance, colonize the gut of these newborns with beneficial flora, and promote growth in these infants. Aims and Objectives: This study was planned to compare the role of probiotics in low birth weight (LBW) infants in the time taken to reach full feeds, episodes of feed intolerance, weight gain, duration of hospital stay, incidence of necrotizing enterocolitis (NEC) stage 2 or more, and morbidity and mortality during hospital stay. Materials and Methods: This interventional two-arm blinded randomized control study was conducted in Thoothukudi Government Medical College Hospital, Thoothukudi, from November 2019 to October 2020. The selected sample of babies was randomly divided into two groups, the probiotic and the no-probiotic group. Bifidobacterium breve M-16 was administered to infants in the probiotic group at a dose of 0.5 g/day once a day in breast milk. Only breast milk was used to feed babies in the no-probiotic group. Results: The time to reach full enteral feed was shorter in the probiotic group (9.21±1.74 days) than in the no-probiotic group (12.43±3.74 days). Better feed tolerance (12%) was seen in the probiotic group than in the no-probiotic (44%) group. A low incidence of sepsis (12%) was seen in the probiotic group than in the non-probiotic group (40%). A lesser duration of hospital stay (10.42±1.77 days) was seen in the probiotic group than in the probiotic group (13.78±4.18 days). Conclusion: Very LBW neonates who received probiotic supplements along with their feeds have shorter times to reach full feeds, greater feed tolerance, lower rates of sepsis, and shorter mean hospital stays.

Associations between maternal urinary kisspeptin in late pregnancy and decreased fetal growth: a pregnancy-birth cohort study.

Kisspeptin has been indicated to be a biomarker of fetal growth. Although some evidence suggested that maternal kisspeptin concentrations in early pregnancy were associated with increased fetal growth, studies are still limited and the effect of kisspeptin in late pregnancy remains unknown. This study aimed to investigate the associations between maternal kisspeptin in late pregnancy and fetal growth. Based on the Shanghai-Minhang Birth Cohort study, 724 mother-neonate pairs were included in this study. We measured maternal kisspeptin concentrations in the urine samples collected in late pregnancy and neonatal anthropometric indices at birth. The associations between maternal kisspeptin and neonatal anthropometry were investigated using multiple linear regression models. Higher maternal urinary kisspeptin concentrations were associated with lower neonatal birth weight, head circumference, upper arm circumference, abdominal skinfold thickness, triceps skinfold thickness, and back skinfold thickness. The inverse associations were more pronounced for the highest kisspeptin levels versus the lowest. These patterns were consistent in analyses stratified by neonatal sex, with notably stable associations between maternal kisspeptin concentrations and skinfold thickness. The present study suggested that maternal kisspeptin concentrations in late pregnancy might be inversely associated with fetal growth. The physiological mechanisms of maternal kisspeptin might differ from those in early pregnancy. Further studies are required to assess associations between maternal kisspeptin and energy homeostasis and explore the physiological roles of kisspeptin in late pregnancy.

Predictors of time to full enteral feeding in low birth weight neonates admitted to neonatal intensive care unit: a prospective follow up study

BackgroundSurvival of LBW infants has increased in recent years because of novel perinatal interventions, but the introduction and advancement of enteral feeds for low birth weight infants is challenging. In Ethiopia the proportion of low birth weight infants is thought to be 17.3%. The purpose of this study was to determine the time to full enteral feeding (FEF) and its predictors in LBW neonates admitted to neonatal intensive care unit in selected hospitals of Addis Ababa, Ethiopia.MethodAn institutional based prospective follow up study was conducted from March 15 to June 15, 2022 among 282 LBW neonates admitted to six randomly selected hospitals. Both primary and secondary data was used by interviewing mothers and prospective medical chart review of neonates. The Cox regression model was used and variables having a p-value less than 0.05 with 95% CIs in a multivariable analysis were declared as statistically significant association with time to full enteral feeding.ResultOut of 282 neonates involved in this study, 211 (74.8%) of them reached at FEF. The overall median time to full enteral feeding was 5 days. Predictors significantly associated with time to full enteral feeding were educational level, birth weight, cesarean delivery, hospital acquired infection, being on antibiotics, age at initiation of trophic feeding, routine gastric residual evaluation and NICU location (hospital).ConclusionsThis study demonstrated the difficulty of understanding which low birth weight neonate will attain FEF in a timely manner and factors that affect time to FEF. There is a delay in full enteral feeding achievement among low birth weight neonates and there is a great deal of heterogeneity of practice among health care providers regarding feeding of infants as it was evidenced by a variation in feeding practice among hospitals. Nutrition should be considered as part of the management in neonatal intensive care units since low birth weight neonates are developing edematous malnutrition while they are in the NICU. There should be standard feeding protocol to avoid heterogeneity of practice and additional study should be conducted for each categories of GA and BW with long follow up time.

Successful Awake Caudal Anesthesia for Incarcerated Inguinal Hernia Repair in an Ex-Premature Baby at 8 Weeks of Age.

Introduction: Caudal anesthesia is a standard procedure in pediatric anesthesia because of its excellent safety and success rate. Usually, it is administered after general anesthesia, but in selected neonatal populations, awake caudal anesthesia is a method of choice.&#x0D; Prematurely born, low birth weight neonates are more prone to complications from general anesthesia than term neonates, even after simple surgery. Among these complications, post-operative apnea is the most common.&#x0D; Caudal epidural anesthesia in awake neonates is a recognized technique that enables the avoidance of general anesthesia and the complications associated with it. In skilled hands, it is also theoretically easier to perform consistent caudal anesthesia than an awake subarachnoid block. In our case, we report a successful awake caudal anesthesia in an ex-premature baby in the emergency setting for incarcerated inguinal hernia repair.&#x0D; To our knowledge, this case report on this topic has yet to be published in Armenia.&#x0D; Conclusion: Neuraxial (spinal, epidural, caudal) awake anesthesia is the method of choice for lower abdominal surgery in preterm infants. Both spinal and caudal anesthesia are effective methods; awake caudal anesthesia is a method of choice because of the success rate and lower analgesic requirements in the post-operative period.&#x0D; &#x0D;

Newborn Calf Circumference to Identify Low Birth Weight Neonates

Background: The absence of birth weight records for infants remains a prevalent issue in developing countries, including Indonesia. The timely identification of low birth weight (LBW) and premature neonates, particularly those born outside well-equipped healthcare facilities is vital within the critical first 48 hours of life. This study aimed to ssess the potential utility of calf circumference in identifying low birth weight infants. Subjects and Method: A cross-sectional study was conducted on 100 neonates aged between 0 – 48 hours old who were treated at Dr. Moewardi General Hospital, Surakarta from May 2022 to August 2022. The dependent variable was neonates birth weight. The independent variables was calf circumference. Calf circumference was measured using non elastic but flexible measuring tape, with measure­ment precision up to the nearest 0.1 cm. The cut-off point of calf circumference was determined with the ROC curve. Results: Calf circumference significantly correlates with birth weight (p&lt;0.001), with r=0.969. The calf circumference cut-off value of 10.35 cm in LBW had an AUC of 0.99, a sensitivity of 98.0%, a specificity of 98.0%, and a positive predictive value of 98.0%, a negative predictive value of 98.0%. The calf circumference cut-off value was 8.85 cm for LBW neonates, which had an AUC of 0.93, with a sensitivity of 83.9%. specificity 85.7%, positive predictive value 98.7%, negative predictive value 28.6%. Conclusion: Calf circumference in newborns can be used to identify neonates with low birth weight. Keywords: calf circumference, birth weight, low birth weight, anthropometry.

Retinopathy of Prematurity in Very Low Birthweight Neonates of Gestation Less Than 32weeks in Malaysia.

To determine the screening rates and incidence of retinopathy of prematurity (ROP), and risk factors associated with ROP in very low birthweight (VLBW, <1500g) neonates of gestation <32 wk admitted to neonatal intensive care units (NICUs) in a middle-income country. It was a retrospective cohort study of prospectively submitted data by 44 Malaysian NICUs participating in the Malaysian National Neonatal Registry. All VLBW neonates of gestation <32 wk born in 2015-2020 and survived to discharge were included. Of 11768 survivors, 90.5% (n = 10436) had ROP screening; 16.1% (1685/10436) had ROP. ROP was significantly more common in neonates <28 wk gestation (extremely preterm, EPT) than ≥28 wk gestation (37.7% vs. 9.7%; p <0.001), and more common in those with birthweight <1000g (extremely low birthweight, ELBW) than ≥1000g (32.9% vs. 9.1%; p <0.001). Multiple logistic regression analysis showed that the significant independent factors associated with increased risk of ROP were ELBW, EPT, Indian ethnic group, vaginal delivery, mechanical ventilation >5 d, high frequency ventilation, total parenteral nutrition, late-onset sepsis, bronchopulmonary dysplasia, and intraventricular hemorrhage. Receiving oxygen therapy at birth was associated with significantly lower risk of ROP. The incidence and severity of ROP increased with decreasing gestation and birthweight. Prolonged duration of oxygen therapy, infection, invasive respiratory support, and conditions commonly causing fluctuations of oxygenation were significant factors associated with increased risk of ROP. Receiving oxygen at birth did not increase risk.
