Fulltext A 2-year study of neonatal mortality in a large Malaysian hospital

Boo NY, Nasri NM, Cheong SK, Sivamohan N

Singapore Med J, 1991 Apr;32(2):142-7.
PMID: 2042076

A 2-year study was carried out in the Maternity Hospital, Kuala Lumpur to determine the neonatal mortality rates. This Hospital functions both as the local service centre as well as the national referral centre in Malaysia. Its neonatal services, however, were equipped and manned at those below Level III perinatal centre. During the study period 52, 877 livebirths took place in the Hospital. In 1987 and 1988 respectively, the low birthweight (less than 2500 gm) rates were: 112.8 and 101.9 per 1000 livebirths, very low birthweight (less than 1500 gm) rates: 11.1 and 8.8 per 1000 livebirths, neonatal mortality rates: 12.5 and 10.7 per 1000 livebirths and neonatal mortality risk ratio: 1.15 and 1.27. There was significant difference in mortality rates among the Malay, Chinese and Indian babies born in this hospital: the Indians had the highest and the Chinese the lowest rates. Babies delivered by breech or lower segment Caesarean section (LSCS) also had significantly higher mortality than those delivered by other modes of delivery. Low birthweight neonates constituted less than 45% of the total special care nursery admission but contributed to more than 70% of the total neonatal deaths. The common causes of neonatal deaths were problems of prematurity, infection, asphyxia and congenital malformations. Preterm and low birthweight neonates died primarily from problems of prematurity or infection. Term and larger neonates died mainly from asphyxia. More than 75% of the neonatal deaths occurred before 7 days of life. Improvement of antenatal care in the community and upgrading of perinatal services in this Hospital could help to lower the morbidity and mortality due to preventable causes.

Mohd Kori AM, Van Rostenberghe H, Ibrahim NR, Yaacob NM, Nasir A

Int J Environ Res Public Health, 2021 Apr 23;18(9).
PMID: 33922783 DOI: 10.3390/ijerph18094509

Caffeine is the most commonly used methyl xanthine for the prevention of apnoea in prematurity, but the ideal dose was uncertain, until now. This study compared two doses of caffeine for the prevention of apnoea in prematurity. A clinical trial was conducted on 78 preterm infants ≤32 weeks in Neonatal Intensive Care Unit. They were randomly allocated to receive the intervention (loading 40 mg/kg/day and maintenance of 20 mg/kg/day) or the control (loading 20 mg/kg/day and maintenance of 10 mg/kg/day) dose of caffeine. The primary outcome of the study was the frequency and total days of apnoea per duration of treatment for both groups. The frequency of apnoea ranged from zero to fourteen in the intervention group and zero to twelve in the control group. There was no statistically significant difference between the groups, with a p-value of 0.839. The number of days of apnoea was also similar between both groups, with a p-value of 0.928. There was also no significant difference in adverse events between both regimens. This study did not support the use of higher doses of caffeine as a prevention for apnoea in prematurity.

Fulltext A Review of Placenta and Umbilical Cord-Derived Stem Cells and the Immunomodulatory Basis of Their Therapeutic Potential in Bronchopulmonary Dysplasia

Chia WK, Cheah FC, Abdul Aziz NH, Kampan NC, Shuib S, Khong TY, et al.

PMID: 33791258 DOI: 10.3389/fped.2021.615508

Bronchopulmonary dysplasia (BPD) is a devastating lung disorder of preterm infants as a result of an aberrant reparative response following exposures to various antenatal and postnatal insults. Despite sophisticated medical treatment in this modern era, the incidence of BPD remains unabated. The current strategies to prevent and treat BPD have met with limited success. The emergence of stem cell therapy may be a potential breakthrough in mitigating this complex chronic lung disorder. Over the last two decades, the human placenta and umbilical cord have gained increasing attention as a highly potential source of stem cells. Placenta-derived stem cells (PDSCs) and umbilical cord-derived stem cells (UCDSCs) display several advantages such as immune tolerance and are generally devoid of ethical constraints, in addition to their stemness qualities. They possess the characteristics of both embryonic and mesenchymal stromal/stem cells. Recently, there are many preclinical studies investigating the use of these cells as therapeutic agents in neonatal disease models for clinical applications. In this review, we describe the preclinical and clinical studies using PDSCs and UCDSCs as treatment in animal models of BPD. The source of these stem cells, routes of administration, and effects on immunomodulation, inflammation and regeneration in the injured lung are also discussed. Lastly, a brief description summarized the completed and ongoing clinical trials using PDSCs and UCDSCs as therapeutic agents in preventing or treating BPD. Due to the complexity of BPD, the development of a safe and efficient therapeutic agent remains a major challenge to both clinicians and researchers.

A population-based study of birth defects in Malaysia

Thong MK, Ho JJ, Khatijah NN

Ann Hum Biol, 2005 Mar-Apr;32(2):180-7.
PMID: 16096215 DOI: 10.1080/03014460500075332

Birth defects are one of the leading causes of paediatric disability and mortality in developed and developing countries. Data on birth defects from population-based studies originating from developing countries are lacking. One of the objectives of this study was to determine the epidemiology of major birth defects in births during the perinatal period in Kinta district, Perak, Malaysia over a 14-month period, using a population-based birth defect register. There were 253 babies with major birth defects in 17,720 births, giving an incidence of 14.3/1000 births, a birth prevalence of 1 in 70. There were 80 babies with multiple birth defects and 173 with isolated birth defects. The exact syndromic diagnosis of the babies with multiple birth defects could not be identified in 18 (22.5%) babies. The main organ systems involved in the isolated birth defects were cardiovascular (13.8%), cleft lip and palate (11.9%), clubfeet (9.1%), central nervous system (CNS) (including neural tube defects) (7.9%), musculoskeletal (5.5%) and gastrointestinal systems (4.7%), and hydrops fetalis (4.3%). The babies with major birth defects were associated with lower birth weights, premature deliveries, higher Caesarean section rates, prolonged hospitalization and increased specialist care. Among the cohort of babies with major birth defects, the mortality rate was 25.2% during the perinatal period. Mothers with affected babies were associated with advanced maternal age, birth defects themselves or their relatives but not in their other offspring, and significantly higher rates of previous abortions. The consanguinity rate of 2.4% was twice that of the control population. It is concluded that a birth defects register is needed to monitor these developments and future interventional trials are needed to reduce birth defects in Malaysia.

Malaysian Journal of Child Health, 1993;5(1):9-19.
MyJurnal

An analysis of perinatal statistics in Peninsular Malaysia from 1980 — 1989 was undertaken. The Perinatal Mortality Rate showed a 42% decrease over the 10 year period. The Perinatal Mortality Rate was higher among the Indian and Malay ethnic groups compared to the Chinese. This was largely contributed by the higher Stillbirth rate in the former 2 ethnic groups. The Indians have the highest rate of low birthweight babies. There is a decline in the rate of low birthweight babies born over the studied decade. The major causes of early neonatal mortality included problems asociated with prematurity, asphyxia neonatorum, septicaemia and congenital anomalies. Further epi-demiological research is required to identify other riskfactors which contribute to this ethnic biased perinatal mortality rates. Besides intensifying and upgrading current multifaceted approaches, interventional strategies need to be directed to the identified high risk groups. (Copied from article).

A survey among healthcare professionals from seven countries reported diverse nutritional practices of late preterm infants

Cheang HK, Yeung CY, Cheah I, Tjipta GD, Lubis BM, Garza-Bulnes R, et al.

Acta Paediatr, 2022 Jul;111(7):1362-1371.
PMID: 35340076 DOI: 10.1111/apa.16344

AIM: To gain insight into nutritional practices and expected growth outcomes of infants born between 34 and 36 gestational weeks defined as late preterm infants (LPT).
METHODS: An anonymous online survey among paediatricians and neonatologists from Bangladesh, Indonesia, Mexico, Nigeria, Malaysia, Singapore and Taiwan was conducted from March until October 2020. The questionnaire consisted of 40 questions on the nutritional management and expected growth outcomes of LPT in and after-hospital care.
RESULTS: Healthcare professionals from low to high Human Development (HDI) countries (n = 322) and very high HDI countries (n = 169) participated in the survey. Human milk was the preferred feeding, resulting in an adequate growth of LPT (weight, length and occipitofrontal circumference), according to a majority of respondents (low to high HDI, 179/265, 68% vs. very high HDI, 73/143, 51%; p = 0.002). The expected growth outcome was higher after-hospital discharge. Less than half of healthcare professionals started enteral feeding during the 1st hour of life. Lactation difficulties, limited access to human milk fortifiers and donor human milk, especially among low to high HDI countries, were reported as major hurdles.
CONCLUSION: Human milk is the first feeding choice for LPT. The diverse opinions on nutritional practices and expected growth outcomes among healthcare professionals indicate the necessity to develop general nutritional guidelines for LPT.

ABM Position Statement: Paid Maternity Leave-Importance to Society, Breastfeeding, and Sustainable Development

Bettinelli ME, Smith JP, Haider R, Sulaiman Z, Stehel E, Young M, et al.

Breastfeed Med, 2024 Mar;19(3):141-151.
PMID: 38489526 DOI: 10.1089/bfm.2024.29266.meb

Background: Paid maternity leave benefits all of society, reducing infant mortality and providing economic gains. It is endorsed by international treaties. Paid maternity leave is important for breastfeeding, bonding, and recovery from childbirth. Not all mothers have access to adequate paid maternity leave. Key Information: Paid leave helps meet several of the 17 United Nations' Sustainable Development Goals (2, 3, 4, 5, 8, and 10), including fostering economic growth. A family's expenses will rise with the arrival of an infant. Paid leave is often granted with partial pay. Many low-wage workers earn barely enough to meet their needs and are unable to take advantage of paid leave. Undocumented immigrants and self-employed persons, including those engaging in informal work, are often omitted from maternity leave programs. Recommendations: Six months of paid leave at 100% pay, or cash equivalent, should be available to mothers regardless of income, employment, or immigration status. At the very minimum, 18 weeks of fully paid leave should be granted. Partial pay for low-wage workers is insufficient. Leave and work arrangements should be flexible whenever possible. Longer flexible leave for parents of sick and preterm infants is essential. Providing adequate paid leave for partners has multiple benefits. Increasing minimum wages can help more families utilize paid leave. Cash benefits per birth can help informal workers and undocumented mothers afford to take leave. Equitable paid maternity leave must be primarily provided by governments and cannot be accomplished by employers alone.

Admission hypothermia among VLBW infants in Malaysian NICUs

Boo NY, Guat-Sim Cheah I, Malaysian National Neonatal Registry

J Trop Pediatr, 2013 Dec;59(6):447-52.
PMID: 23774951 DOI: 10.1093/tropej/fmt051

This study aimed to determine the prevalence of admission hypothermia (AH) among very-low-birth-weight (≤1500 g) infants in 32 Malaysian neonatal intensive care units (NICUs). This was a retrospective analysis of prospectively collected data of all very-low-birth-weight infants admitted and a questionnaire survey of the practice of AH prevention. Of the 3768 (99.8%) infants with admission temperature recorded, 64.8% (n = 2440) were hypothermic: 40.3% (n = 983) mildly (36.0-36.4°C), 58.5% (n = 1428) moderately (32.0-35.9°C) and 1.2% (n = 29) severely (<32.0°C). Mean ambient temperature of these NICUs was 22.8°C (SD = 2.7, n = 28) in labour rooms and 20.1°C (SD = 1.6, n = 30) in operation theatres. None of the NICUs practised complete care bundle against AH at birth (i.e. use of pre-warmed radiant warmer and cling wrap, ambient temperature of at least 25°C and use of pre-warmed transport incubator). Care bundle against neonatal hypothermia should be actively promoted in Malaysian labour rooms and operation theatres.

Algorithms that eliminate the effects of calibration artefact and trial-imposed offsets of Masimo oximeter in BOOST-NZ trial

Zahari M, Lee DS, Darlow BA

J Clin Monit Comput, 2016 Oct;30(5):669-78.
PMID: 26282827 DOI: 10.1007/s10877-015-9752-1

The displayed readings of Masimo pulse oximeters used in the Benefits Of Oxygen Saturation Targeting (BOOST) II and related trials in very preterm babies were influenced by trial-imposed offsets and an artefact in the calibration software. A study was undertaken to implement new algorithms that eliminate the effects of offsets and artefact. In the BOOST-New Zealand trial, oxygen saturations were averaged and stored every 10 s up to 36 weeks' post-menstrual age. Two-hundred and fifty-seven of 340 babies enrolled in the trial had at least two weeks of stored data. Oxygen saturation distribution patterns corresponding with a +3 % or -3 % offset in the 85-95 % range were identified together with that due to the calibration artefact. Algorithms involving linear and quadratic interpolations were developed, implemented on each baby of the dataset and validated using the data of a UK preterm baby, as recorded from Masimo oximeters with the original software and a non-offset Siemens oximeter. Saturation distributions obtained were compared for both groups. There were a flat region at saturations 85-87 % and a peak at 96 % from the lower saturation target oximeters, and at 93-95 and 84 % respectively from the higher saturation target oximeters. The algorithms lowered the peaks and redistributed the accumulated frequencies to the flat regions and artefact at 87-90 %. The resulting distributions were very close to those obtained from the Siemens oximeter. The artefact and offsets of the Masimo oximeter's software had been addressed to determine the true saturation readings through the use of novel algorithms. The implementation would enable New Zealand data be included in the meta-analysis of BOOST II trials, and be used in neonatal oxygen studies.

Fulltext Amino acid dosing in parenteral nutrition for very low birth weight preterm neonates: an outcome assessment

Kamarudin NA, Manan MM, Zulkifly HH, Neoh CF, Ali SM, Ming LC

Asia Pac J Clin Nutr, 2016;25(1):53-61.
PMID: 26965762 DOI: 10.6133/apjcn.2016.25.2.02

This study aimed to investigate the effects of parenteral nutrition (PN) administration of amino acids (AA) on physical changes among very low birth weight infants in a local hospital setting in Malaysia. A retrospective study was carried out at a hospital in Malaysia. Records of neonates prescribed PN in the neonatal unit in 2012 were screened for eligibility. A total of 199 premature neonates received PN support in the year 2012 and, of these, 100 fulfilled the inclusion criteria. The median value of AA intake on the first day of PN was 2.00 (<28 weeks group); 1.00 (28-31 weeks group) and 0.75 (>31 weeks group). Neonates in the <28 weeks group were more likely to receive AA at an earlier time and higher initial dose compared with the other age groups. The study also found that there was no statistically significant difference in the dose of AA on the first day of PN administration and that the significant variations in nutritional parameters among the subjects did not lead to differences in physical outcomes. This study identified that when PN is provided in the local hospital setting, it is likely that the current nutritional practices are inadequate to achieve the standard growth recommendations. Our findings call for a need to optimize AA and calorie intake since growth restriction is a morbidity which will affect the infants' growth and development. Current prescriptions for PN in this hospital need to be reviewed in order to improve patient outcomes.

Fulltext Association Between Enteral Supplementation With High-Dose Docosahexaenoic Acid and Risk of Bronchopulmonary Dysplasia in Preterm Infants: A Systematic Review and Meta-analysis

Marc I, Boutin A, Pronovost E, Perez Herrera NM, Guillot M, Bergeron F, et al.

JAMA Netw Open, 2023 Mar 01;6(3):e233934.
PMID: 36943265 DOI: 10.1001/jamanetworkopen.2023.3934

IMPORTANCE: High-dose docosahexaenoic acid (DHA), a long-chain polyunsaturated fatty acid, may affect the risk of bronchopulmonary dysplasia (BPD). However, high-level summative evidence supporting such clinical association in very preterm infants is lacking.
OBJECTIVE: To examine the association between enteral supplementation with high-dose DHA during the neonatal period and the risk of BPD in preterm infants born at less than 29 weeks' gestation.
DATA SOURCES: PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials, medRxiv, and ClinicalTrials.gov were searched from inception to August 1, 2022, for eligible articles with no language restrictions.
STUDY SELECTION: Randomized clinical trials (RCTs) were eligible for inclusion (1) if their interventions involved direct administration of a minimum DHA supplementation of 40 mg/kg/d or breast milk or formula feeding of at least 0.4% of total fatty acids, and (2) if they reported data on either BPD, death, BPD severity, or a combined outcome of BPD and death.
DATA EXTRACTION AND SYNTHESIS: Two investigators completed independent review of titles and abstracts, full text screening, data extraction, and quality assessment using the Cochrane Risk of Bias 2.0. Risk ratios (RRs) with 95% CIs were pooled using random-effect meta-analyses.
MAIN OUTCOMES AND MEASURES: Primary outcome was BPD using trial-specific definitions, which was further stratified for RCTs that used a more stringent BPD definition based on systematic pulse oximetry assessment at 36 weeks' postmenstrual age. Other outcomes were BPD, death, BPD severity, or combined BPD and death.
RESULTS: Among the 2760 studies screened, 4 RCTs were included, which involved 2304 infants (1223 boys [53.1%]; mean [SD] gestational age, 26.5 [1.6] weeks). Enteral supplementation with high-dose DHA was associated with neither BPD (4 studies [n = 2186 infants]; RR, 1.07 [95% CI, 0.86-1.34]; P = .53; I2 = 72%) nor BPD or death (4 studies [n = 2299 infants]; RR, 1.04 [95% CI, 0.91-1.18]; P = .59; I2 = 61%). However, an inverse association with BPD was found in RCTs that used a more stringent BPD definition (2 studies [n = 1686 infants]; RR, 1.20 [95% CI, 1.01-1.42]; P = .04; I2 = 48%). Additionally, DHA was inversely associated with moderate-to-severe BPD (3 studies [n = 1892 infants]; RR, 1.16 [95% CI, 1.04-1.29]; P = .008; I2 = 0%).
CONCLUSIONS AND RELEVANCE: Results of this study showed that enteral supplementation with high-dose DHA in the neonatal period was not associated overall with BPD, but an inverse association was found in the included RCTs that used a more stringent BPD definition. These findings suggest that high-dose DHA supplementation should not be recommended to prevent BPD in very preterm infants.

Fulltext Association between Breastfeeding Attitudes and Postpartum Depression among Mothers with Premature Infants during COVID-19 Pandemic

Yahya NFS, Teng NIMF, Shafiee N, Juliana N

Int J Environ Res Public Health, 2021 10 17;18(20).
PMID: 34682652 DOI: 10.3390/ijerph182010915

Breastfeeding is the best form of feeding for premature infants. However, mothers with premature delivery are frequently reported to be depressed, and this has been especially the case during the Coronavirus Disease-2019 (COVID-19) pandemic. We aimed to measure the level of breastfeeding attitude and its association with postpartum depression among mothers with premature infants in the Neonatal Intensive Care Unit (NICU) during the COVID-19 pandemic. A total of 248 mothers with a premature infant were observed in this cross-sectional study from the chosen NICUs of government hospitals in Selangor, Malaysia. The Iowa Infant Feeding Attitude Score (IIFAS) and the Edinburgh Postnatal Depression Scale, along with sociodemographic questionnaires, were used to obtain information on the mothers' attitudes towards breastfeeding and the risk of postpartum depression. A higher percentage of mothers had a positive attitude towards breastfeeding (64.9%), with a mean IIFAS score of 66.30 ± 6.92. Meanwhile, about 27% of mothers with premature infants were reported to have high risk of depressive symptoms. Mothers with a high risk of depression were less likely to have a positive attitude towards breastfeeding (OR 0.37, 95% CI 0.199, 0.675) as compared to mothers with a low risk of depression (p < 0.01). We found that there is an association between the risk of depression and the attitude towards breastfeeding. Early identification of maternal mental health problems should be addressed to ensure the willingness of mothers to continue breastfeeding.

Automated oxygen delivery for preterm infants with respiratory dysfunction

Stafford IG, Lai NM, Tan K

Cochrane Database Syst Rev, 2023 Nov 30;11(11):CD013294.
PMID: 38032241 DOI: 10.1002/14651858.CD013294.pub2

BACKGROUND: Many preterm infants require respiratory support to maintain an optimal level of oxygenation, as oxygen levels both below and above the optimal range are associated with adverse outcomes. Optimal titration of oxygen therapy for these infants presents a major challenge, especially in neonatal intensive care units (NICUs) with suboptimal staffing. Devices that offer automated oxygen delivery during respiratory support of neonates have been developed since the 1970s, and individual trials have evaluated their effectiveness.
OBJECTIVES: To assess the benefits and harms of automated oxygen delivery systems, embedded within a ventilator or oxygen delivery device, for preterm infants with respiratory dysfunction who require respiratory support or supplemental oxygen therapy.
SEARCH METHODS: We searched CENTRAL, MEDLINE, CINAHL, and clinical trials databases without language or publication date restrictions on 23 January 2023. We also checked the reference lists of retrieved articles for other potentially eligible trials.
SELECTION CRITERIA: We included randomised controlled trials and randomised cross-over trials that compared automated oxygen delivery versus manual oxygen delivery, or that compared different automated oxygen delivery systems head-to-head, in preterm infants (born before 37 weeks' gestation).
DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our main outcomes were time (%) in desired oxygen saturation (SpO2) range, all-cause in-hospital mortality by 36 weeks' postmenstrual age, severe retinopathy of prematurity (ROP), and neurodevelopmental outcomes at approximately two years' corrected age. We expressed our results using mean difference (MD), standardised mean difference (SMD), and risk ratio (RR) with 95% confidence intervals (CIs). We used GRADE to assess the certainty of evidence.
MAIN RESULTS: We included 18 studies (27 reports, 457 infants), of which 13 (339 infants) contributed data to meta-analyses. We identified 13 ongoing studies. We evaluated three comparisons: automated oxygen delivery versus routine manual oxygen delivery (16 studies), automated oxygen delivery versus enhanced manual oxygen delivery with increased staffing (three studies), and one automated system versus another (two studies). Most studies were at low risk of bias for blinding of personnel and outcome assessment, incomplete outcome data, and selective outcome reporting; and half of studies were at low risk of bias for random sequence generation and allocation concealment. However, most were at high risk of bias in an important domain specific to cross-over trials, as only two of 16 cross-over trials provided separate outcome data for each period of the intervention (before and after cross-over). Automated oxygen delivery versus routine manual oxygen delivery Automated delivery compared with routine manual oxygen delivery probably increases time (%) in the desired SpO2 range (MD 13.54%, 95% CI 11.69 to 15.39; I2 = 80%; 11 studies, 284 infants; moderate-certainty evidence). No studies assessed in-hospital mortality. Automated oxygen delivery compared to routine manual oxygen delivery may have little or no effect on risk of severe ROP (RR 0.24, 95% CI 0.03 to 1.94; 1 study, 39 infants; low-certainty evidence). No studies assessed neurodevelopmental outcomes. Automated oxygen delivery versus enhanced manual oxygen delivery There may be no clear difference in time (%) in the desired SpO2 range between infants who receive automated oxygen delivery and infants who receive manual oxygen delivery (MD 7.28%, 95% CI -1.63 to 16.19; I2 = 0%; 2 studies, 19 infants; low-certainty evidence). No studies assessed in-hospital mortality, severe ROP, or neurodevelopmental outcomes. Revised closed-loop automatic control algorithm (CLACfast) versus original closed-loop automatic control algorithm (CLACslow) CLACfast allowed up to 120 automated adjustments per hour, whereas CLACslow allowed up to 20 automated adjustments per hour. CLACfast may result in little or no difference in time (%) in the desired SpO2 range compared to CLACslow (MD 3.00%, 95% CI -3.99 to 9.99; 1 study, 19 infants; low-certainty evidence). No studies assessed in-hospital mortality, severe ROP, or neurodevelopmental outcomes. OxyGenie compared to CLiO2 Data from a single small study were presented as medians and interquartile ranges and were not suitable for meta-analysis.
AUTHORS' CONCLUSIONS: Automated oxygen delivery compared to routine manual oxygen delivery probably increases time in desired SpO2 ranges in preterm infants on respiratory support. However, it is unclear whether this translates into important clinical benefits. The evidence on clinical outcomes such as severe retinopathy of prematurity are of low certainty, with little or no differences between groups. There is insufficient evidence to reach any firm conclusions on the effectiveness of automated oxygen delivery compared to enhanced manual oxygen delivery or CLACfast compared to CLACslow. Future studies should include important short- and long-term clinical outcomes such as mortality, severe ROP, bronchopulmonary dysplasia/chronic lung disease, intraventricular haemorrhage, periventricular leukomalacia, patent ductus arteriosus, necrotising enterocolitis, and long-term neurodevelopmental outcomes. The ideal study design for this evaluation is a parallel-group randomised controlled trial. Studies should clearly describe staffing levels, especially in the manual arm, to enable an assessment of reproducibility according to resources in various settings. The data of the 13 ongoing studies, when made available, may change our conclusions, including the implications for practice and research.

MyJurnal

With advances in medicine, more and more premature infants who require round-the-clock nursing care due to one or more complex medical conditions are able to survive after receiving intensive treatment in the neonatal intensive care unit (NICU). The increased survival rate has resulted in a higher incidence of morbidity that may impose emotional and financial burdens on families, society and the healthcare system. This paper explores the experiences of mothers with premature babies who were admitted to a NICU. A generic qualitative approach was used to gain insights into the effects of the premature baby admission to a NICU through tape recorded semi structured open-ended questions interviews with 17 mothers whose premature babies were admitted to a NICU. Inductive thematic analysis was used to identify, analyse, and report themes and patterns within the data. Qualitative analysis of the descriptive data obtained from 17 mothers identified four major themes and 13 sub themes relating to avoidance, effects of the separation, ceremonies and inadequate preparation. The findings have several implications for practice by care professionals. It can help nurses to develop interventions to prepare mothers to cope with new situations, decreasing stress and psychological problems regarding the admission of their infants to the NICU.

Biosocial variances and infant survival: a path analysis approach

Frisch AS, Kallen DJ, Griffore RJ, Dolanski EA

J Biosoc Sci, 1992 Apr;24(2):175-83.
PMID: 1583032

This study used path analysis to assess the chances of survival of babies in a neonatal intensive care unit in Lansing, Michigan, USA. Two paths to neonatal survival were identified and the variables accounted for 20% of the variance in gestational age. The first path showed that prior infant losses were negatively correlated with gestational age while in the second path, gestational age showed negative relationships with pre-pregnancy weight and household job worries.

COVID-19 in a premature infant

Ng DC, Chin L, Choo PPL, Paramasivam U

BMJ Case Rep, 2021 May 31;14(5).
PMID: 34059550 DOI: 10.1136/bcr-2021-243783

We report a case of COVID-19 in a 29-week preterm infant. This child is the youngest reported case of SARS-CoV-2 infection in Malaysia, and to the best of our knowledge, one of the youngest documented cases of established vertical transmission of SARS-CoV-2 reported in literature. Our report highlights the clinical course, timelines of viral shedding by real-time reverse transcription-PCR and antibody seroconversion in a premature infant infected with SARS-CoV-2. In addition, we discuss the challenges faced in managing a preterm infant infected with SARS-CoV-2 and the knowledge gaps that need to be explored.

Pericardial effusion with cardiac tamponade is a rare and life-threatening complication of peripherally inserted central catheter (PICC) in a neonate. We report a 33-week preterm neonate who had sudden clinical deterioration at day seven of total parenteral nutrition regime via PICC. Recognition of pericardial effusion with cardiac tamponade in neonates with a PICC requires a high index of suspicion and steps in prevention include proper catheter tip placement and continuous monitoring of line position and function.

To report observations of horizontal corneal diameter (HCD) and central corneal thickness (CCT) changes in premature infants with stable optic disc cupping and intraocular pressures (IOPs). The HCD and CCT at term serve as a baseline for premature infants.Sixty-three premature infants were enrolled in a prospective case series. HCD, CCT, and IOP were measured. RetCam images of the optic discs were used to evaluate the cup-disc ratio (CDR) and read by an independent masked observer. Data were collected at between preterm (32-36 weeks) and again at term (37-41 weeks) postconceptual age. Left eye measurements were used for statistical analysis. Left eye findings were combined to construct predictive models for HCD and CCT.The mean HCD was 9.1 mm (standard deviation [SD] = 0.7 mm) at preterm and 10.0 mm (SD = 0.52 mm) at term. The mean CCT preterm was 618.8 (SD = 72.9) μm and at term 563.9 (SD = 50.7) μm, respectively. The average preterm CDR was 0.31 and at maturity was 0.33. Average IOP of preterm and term was 13.1 and 14.11 mm Hg, respectively. There was significant linear correlation between HCD with the postmenstrual age (r = 0.40, P infant reached term. Corneal diameter correlated with gestational age at birth and head circumference.
