Purpose. To study the possible effect of protective red light filter glasses as a method of preventing retinopathy of prematurity, based on the phenomenon of preconditioning photostimulation. Material and methods. For this study, we selected 20 children (40 eyes) from 26.5 to 36 weeks of gestational age and a birth weight of 650 to 2650 grams. All children were divided into 2 groups – the main and control groups of 10 children (20 eyes) each. Results. In the main group of the study, with the use of protective red light filter glasses, the best indicators of the electroretinogram were noted. Conclusions. The use of glasses with red protective light filters-as a method based on the phenomenon of preconditioning photostimulation, is a simple and affordable method of preventing retinopathy of prematurity, which reduces the need for surgical laser treatment and the number of adverse outcomes of this disease. Key words: retinopathy of prematurity, methods of prevention of retinopathy of prematurity.

To assess the physical and mental development of infants born after in vitro fertilization (IVF), we performed a general physical and developmental examination (Bayley and Stanford-Binet scales) on a cohort of 116 IVF children, conceived and born at our institution between February 1985 and March 1989, and on 116 non-IVF matched controls. Study and control groups were each composed of 66 singletons, 19 pairs of twins and 4 sets of triplets, whose age at examination ranged from 12 to 45 months. The developmental indices of IVF infants were within the normal range and did not differ from those of their matched controls. The indices were positively correlated to gestational age, birth weight, head circumference at birth and at examination, and mother's education. Mean birth weight, gestational age, and birth weight percentile of IVF infants were lower than the mean of the healthy population. Mean percentiles of weight and length at examination (mean age 22.4 months) were equally low but did not differ from those of the matched controls. However, mean percentiles of head circumference at birth and at examination compare well with the normal mean, both in IVF and control groups. Twins and triplets (IVF and controls) had significantly lower physical and mental indices as compared to singletons.

Abstract Background Poor weight gain in the first few weeks of life has been studied as a predictor of retinopathy of prematurity (ROP). Our aim was to assess whether time taken to regain birthweight (BW) be used as an additional marker to identify infants with type 1 ROP. Methods In this retrospective study, preterm infants (< 27 weeks gestational age at birth) born during the period from 1/1/2010–31/12/2015 at a tertiary neonatal intensive care unit in Australia were included. Twenty-seven preterm infants with Type 1 ROP were identified. Controls (No ROP or ROP other than type 1) were matched with cases on gestational age at birth and BW (1:4 ratio). Data were collected from the database and medical records. Results The median (IQR) gestational age for Type 1 ROP and control groups were 24 (24–26) and 25 (24–26) weeks respectively and median (IQR) BW for Type 1 ROP and control groups were 675 (635–810) and 773 (666–884) grams respectively. Preterm infants with Type 1 ROP were more likely to be small for gestational age (SGA) (18.5% vs 3.7%, p = 0.015) and had increased weeks on oxygen therapy (median 11.9 vs 9.1, p = 0.028). Time to regain BW was longer in preterm infants with type 1 ROP than controls but did not reach statistical significance (median 9 vs 7 days, OR 1.08, 95% CI 1.00–1.17, p = 0.059) adjusted for SGA and duration of oxygen therapy. The area under the curve from the time to regain BW model with adjustment for SGA and duration of oxygen therapy was 0.73 (95% CI 0.62–0.83). Conclusion We hypothesize that time to regain BW has potential to aid prediction of Type 1 ROP and this warrants further investigation in a larger prospective study.

Objectives: To investigate the expression of CD64 and CD11b neutrophils in neonates with necrotizing enterocolitis (NEC) and to evaluate the diagnostic value of CD64 and CD11b in identifying NEC in neonates. Methods: A total of 138 newborns, admitted to our neonatal intensive care unit from October 2018 to March 2020, were recruited in this study. The subjects were divided into the NEC and control groups, according to the method of case-control. The expression of CD64, CD11b, and C-reactive protein (CRP) was measured in the peripheral blood, the sensitivity and specificity of each index in diagnosing NEC were compared, and their diagnostic value was examined. Results: The corrected gestational age of the NEC and control groups was 32.29 ± 1.85 and 33.24 ± 1.98 weeks, respectively. The mean birth weight of the two groups was 1654 ± 373 and 1746 ± 400 g, respectively. Also, the mean age at sampling was 11.6 ± 3.11 and 11.7 ± 3.14 days in the NEC and control groups, respectively. Gender, corrected gestational age, mean birth weight, and sampling age were not significantly different between the groups (P > 0.05). The CD64 and CD11b expression levels were higher in the NEC group, compared to the control group (P < 0.01). Comparison of the NEC group by stage showed that the CD64 and CD11b indices were the highest in stage III, followed by stage II and stage I (P = 0.01). However, both indices showed a downward trend during the recovery period (P < 0.01). A CD64 level ≥ 0.71, a CD11b level of 1.94, and a CRP level ≥ 7.38 were considered as the best diagnostic criteria. The highest exponential sensitivity (82.7%) was attributed to the CD64 index, followed by CD11b (50.8%) and CRP (39.1%). The highest sensitivity (89%) was obtained by a combination of two indices (one positive index); also, when both indices were positive, the highest specificity (87%) was reported. The sensitivity of combined indices for NEC diagnosis in stage I, II and III were 84.4%, 95.7%, and 92.9%, respectively. Conclusions: The expression levels of CD64 and CD11b neutrophils in neonatal NEC increased and was associated with the severity of NEC. Monitoring of changes in the two indices had a clinical value in the diagnosis of NEC. In conclusion, the combined use of these two indices can be more valuable in the diagnosis of neonatal NEC.

Twin Pregnancies

Twin pregnancies are commonly assessed using singleton growth and birth weight reference charts. This practice has led to a significant number of twins labelled as small for gestational age (SGA), causing unnecessary interventions and increased risk of iatrogenic preterm birth. However, the use of twin-specific charts remains controversial. This study aims to assess whether twin-specific estimated fetal weight (EFW) and birth weight (BW) charts are more predictive of adverse outcomes compared to singleton charts. Centiles of EFW and BW were calculated using previously published singleton and twin charts. Categorical data were compared using Chi-square or McNemar tests. The study included 1740 twin pregnancies, with the following perinatal adverse outcomes recorded: perinatal death, preterm birth <34 weeks, hypertensive disorders of pregnancy (HDP) and admissions to the neonatal unit (NNU). Twin-specific charts identified prenatally and postnatally a smaller proportion of infants as SGA compared to singleton charts. However, twin charts showed a higher percentage of adverse neonatal outcomes in SGA infants than singleton charts. For example, perinatal death (SGA 7.2% vs. appropriate for gestational age (AGA) 2%, p < 0.0001), preterm birth <34 weeks (SGA 42.1% vs. AGA 16.4%, p < 0.0001), HDP (SGA 21.2% vs. AGA 13.5%, p = 0.015) and NNU admissions (SGA 69% vs. AGA 24%, p < 0.0001), when compared to singleton charts (perinatal death: SGA 2% vs. AGA 1%, p = 0.029), preterm birth <34 weeks: (SGA 20.6% vs. AGA 17.4%, p = 0.020), NNU admission: (SGA 34.5% vs. AGA 23.9%, p < 0.000). There was no significant association between HDP and SGA using the singleton charts (p = 0.696). In SGA infants, according to the twin charts, the incidence of abnormal umbilical artery Doppler was significantly more common than in SGA using the singleton chart (27.0% vs. 8.1%, p < 0.001). In conclusion, singleton charts misclassify a large number of twins as at risk of fetal growth restriction. The evidence suggests that the following twin-specific charts could reduce unnecessary medical interventions prenatally and postnatally.

Introduction: Low birth weight (LBW) infants who have been hospitalized are exposed to various conditions that provoke discomfort, which could trigger a stress response and growth disorders. This study aimed to identify the effects of auditory stimuli from Murottal Quran when it comes to the comfort and weight of LBW infants.Methods: This study used a clinical randomized controlled trial design involving 52 low birth weight infants. The infants were randomly assigned to either the intervention group (n=26) or the control (n=26). The intervention of Murottal Quran was given using a speaker 4 times a day for 20 minutes every 3 hours. This intervention was conducted for three days.Results: The results of this study show that there is a significant difference in the comfort of  low birth weight infants after Murottal Qur’an on the first, second, and third days between the intervention and control groups (p=0.014; <0.001; <0.001). There was no significant difference in the weight between the intervention and control groups in the first, second, and third days (p=0.481; 0.481; 0.464).Conclusion: The auditory stimuli of Murottal Quran can help to improve the comfort level of low birth weight infants during hospitalization. It can therefore be used as a supportive therapy to facilitate low birth weight infant and premature infant development.

A Prospective Study

Background: Recent advances in neonatal care in the last decade and improved survival rates have resulted in an apparent increase in the incidence of retinopathy of prematurity (ROP), which is the most important cause of preventable blindness in infants. This study was done to identify the risk factors which predispose to ROP and to assess its correlation with severity of ROP.Methods: A total of 140 neonates with gestational age ≤34 weeks, birth weight ≤2000 grams who were admitted at NICU, S. N. Medical College and HSK Hospital, Bagalkot from December 2018 to May 2019 were considered. Babies were assessed and recorded for the risk factors of ROP in a predesigned proforma. ROP screening was performed using wide-field digital imaging on a retcam shuttle (Clarity MSI, USA).Results: A total of 140 babies were examined, and an overall incidence of ROP was 52 (37.1%). 17 (32.7%) had stage 3, 3 (5.8%) had stage 4, and 1 (1.9%) had stage 5. Among the 52 babies with ROP, 19 (51.3%) underwent laser photoablation. Risk factors like gestational age, birth weight, maternal risk factors, apnea, intrauterine growth restriction (IUGR), hypoglycaemia, respiratory distress syndrome (RDS), sepsis, coronary heart disease (CHD), blood transfusion and oxygen requirement duration were significantly associated with ROP. Delay in the establishment of feeds has been associated with ROP (p<0.001).Conclusions: Screening should be intensified in the presence of risk factors which can reduce the incidence of severe stages of ROP as highlighted by this study.

World Health Organization’s Vision 2020 program has recognized Retinopathy of Prematurity(ROP) as an important cause of childhood blindness in industrialized and developing countries. Inthe last few years, it has been identifi ed in many under developed countries as well, as a result ofimproved neonatal intensive care. In Nepal, ROP screening is carried out in a few tertiary hospitalsbut there is no published data on this disease. The purpose of this study was to fi nd out the incidence,severity and risk factors of ROP among infants screened in a tertiary care hospital in the EasternRegion of Nepal.A prospective cohort study was carried out in neonates with gestational age of 34 weeks or less and,or birth weight of 1700 gm or less born over the period of one year. Dilated fundus examination ofall babies was done by indirect ophthalmoscopy between 2-4 weeks after birth and followed up tillthe retinal vascularization was complete. Classifi cation of ROP was done according to internationalclassifi cation (ICROP). Maternal and neonatal risk factors were also noted.A total of 55 babies fulfi lled the screening criteria. ROP was present in 25.45% (n=14) of the babies.Threshold disease was noted in 5.45% (n=3) of the babies screened. Low birth weight (p<0.01)and low gestational age (p<0.01) was signifi cantly associated with the incidence of ROP. Oxygensupplementation (p=<0.01) was an independent risk factor.ROP screening should be performed in all preterm low birth weight infants where there is availabilityof good neonatal intensive care units. The examination should be intensifi ed in those having riskfactors like oxygen. Further studies in the other tertiary care hospitals in Nepal would help toestablish the screening criteria for Nepalese infants.Key words: Retinopathy of prematurity, Eastern Nepal, screening

In Reply.— Casey's point is well taken. An association between socioeconomic status and infant outcome has been documented. Our study and control groups were not matched on that factor, but on age, race, and gestational age at birth. A retrospective analysis of the socioeconomic status of study and control mothers indicates that they are all of low socioeconomic status (Hollingshead groups 4 and 5) and that there is no significant difference between the study and control groups.

Background/aimsDuring the last decade, improved neonatal care has resulted in increased survival of the most immature infants and improved health of more mature infants. We hypothesise that this has affected incidence and treatment of retinopathy of prematurity (ROP), enabling guidelines for screening to be modified.MethodsIn Sweden, all infants with gestational age (GA) at birth ≤30 weeks are screened for ROP. Results are registered in a web-based register, Swedish National ROP Register, with a coverage rate of 97%. Incidence of ROP and frequency of treatment, aspects on natural course of ROP and number of examinations, are calculated in relation to GA at birth in infants born during 2008–2017.ResultsOf 7249 infants, 31.9% (2310) had ROP and 6.1% (440) were treated. No infant with GA 30 weeks was treated. Incidence of ROP remained similar, but frequency of treatment increased (p=0.023). Over time, GA and birth weight were reduced in infants with ROP and with treated ROP. In the most immature infants, postmenstrual age was lower and postnatal age was higher when any ROP and stage 3 ROP were first detected (p<0.001). At treatment, postmenstrual but not postnatal age of the infant was associated with GA (p<0.001). During the 10-year period, 46 038 examinations were performed.ConclusionModification of Swedish guidelines is proposed, including only infants with a GA of <30 weeks and postponing the first examination with 1 week in infants with GA 26–29 weeks. This would spare many infants from stressful examinations and reduce eye examinations with at least 20%.

Background Retinopathy of prematurity (ROP) is one of the ma-jor causes of infant blindness. There are several factors known asrisk factors for ROP. Recent studies show ROP as a disease ofmultifactorial origin.Objective To report the prevalence of ROP in Cipto MangunkusumoHospital, Jakarta and its relation to several risk factors.Methods A cross-sectional descriptive study was conducted fromDecember 2003-May 2005. All infants with birth weight 2500 gramsor less, or gestational age 37 weeks or less, were enrolled con-secutively and underwent the screening of ROP at 4 to 6 weeks ofchronological age or 31 to 33 weeks of postconceptional age.Result Of 73 infant who met the inclusion criteria, 26% (19 out of73 infant) had ROP in various degrees. About 36.8% (7 out of 19infants) were in stage III or more/threshold ROP. No ROP wasnoted in infants born >35 weeks of gestational age, and birth weight>2100 grams. No severe ROP was found in gestational age >34weeks and birth weight >1600 grams. None of full-term, small forgestational age infants experienced ROP. Birth weight, sepsis,apneu, asphyxia, multiple blood transfusions, and oxygen therapyfor more than 7 days were statistically significant with the develop-ment of ROP. However, using multivariate analysis, only asphyxia,multiple blood transfusions, and oxygen therapy for more than 7days were statistically significant with the development of ROP.Conclusion Screening of ROP should be performed in infantsborn 34 weeks of gestational age and/or birth weight <1600 grams.Infants with birth weight from 1600-<2100 grams need to bescreened only if supplemental oxygen is necessary or with clini-cally severe illness
