Impact of birthweight on health-care utilization during early childhood - a birth cohort study

[Perinatal Networks: Ensuring Regional Care of Pregnant Woman and Newborns]

Health care of pregnant women and their newborns is facing major challenges due to the decline in birth rate and shortage of specialists. In the current discussion about future concepts, the centralization associated with minimum quantities and the necessary safeguarding of care in the area are often construed as conflicting goals. Instead, concepts are needed to guarantee that pregnant women and their children will continue to receive care close to home. The example of the saxony center for feto/neonatal health is used to show how partners in a region can jointly ensure care during pregnancy, birth and the neonatal period on a supra-local and cross-hospital basis. The close cooperation of maximum care providers with regional partners enables comprehensive health care. At the same time, this cooperation enables hospitals to remain attractive employers in structurally weak regions and to provide comprehensive care for young families in need of medical services related to pregnancy and birth through good family and social integration close to home and work. The overriding goals of the saxony center for feto/neonatal health are optimal, guideline-based, interdisciplinary and intersectoral care of pregnant women and premature or sick newborns in the region.

Pregnancy & neonatal outcomes in spondyloarthritis

Limited research has been conducted on the impact of spondylitis (SpA) on fertility, but some studies suggest a higher risk of subfertility in women with SpA compared to the general population. Factors associated with impaired fertility in SpA include pain, fatigue, stiffness, functional disorders, depression, anxiety, negative body image, and the use of nonsteroidal anti-inflammatory drugs (NSAIDs) preconceptionally, while TNF alpha inhibitors may play a role in improving fertility in certain cases. There has been a recent increase in clinical research focused on pregnancy outcomes in SpA. However, clear trends in terms of risk of pregnancy and fetal complications have been slow to emerge and many questions remain for women with SpA planning a pregnancy. This article discusses the current evidence for risk of specific pregnancy and fetal complications in women with axial and psoriatic SpA.

Impact of Low Birth Weight on the Prevalence and Economic Burden of Common Childhood Illnesses Among Under-Five Children in India: Findings From Nationally Representative Surveys

Background Common childhood illnesses such as diarrhea, fever, and acute respiratory infection impose substantial health burdens among under-five children, and Low Birth Weight (LBW) has been associated with an increased prevalence of these illnesses. However, the impact of LBW on healthcare utilization and the economic burden of these illnesses remains understudied. Aim To assess the impact of LBW on the prevalence, healthcare utilization, and Out of Pocket Expenditure (OOPE) for outpatient (OP) treatment of selected Common Childhood Illnesses (CCHI) among under-five children in India. Methodology This study utilized data from two nationally representative surveys conducted in India; National Family Health Survey (NFHS-5) (2019-2021) and the National Sample Survey Organization (NSSO) 75th Round Schedule Social Consumption: Health (2017-2018). Data from the NFHS-5 was analyzed to assess the impact of LBW on the prevalence of selected CCHI and healthcare utilization. Comparison of OOPE for OP treatment of selected CCHI between LBW and Normal Birth Weight (NBW) children done using the median OOPE for OP visits of CCHI estimated from the NSSO data. Results The two-week prevalence of selected CCHI among LBW and NBW children was found to be 20.0% (95% CI 19.6 -20.4) and 18.0% (95% CI 17.8 -18.2), respectively. There was no significant difference between LBW and NBW children on healthcare utilization for the treatment of CCHI; both groups had a similar proportion (around 70%) of formal medical treatment utilization for CCHI. The median OOPE spending for OP visits per episode of CCHI was comparable between LBW and NBW children. However, families of LBW children had higher annual OOPE spending for OP visits related to CCHI, with projected estimates of INR 1,446 ($19.56) for LBW children and INR 1,271 ($17.2) for NBW children. Conclusion LBW was associated with a higher prevalence of CCHI. Even though healthcare utilization was similar among LBW and NBW children, a higher prevalence of CCHI among LBW children led to higher OOPE. LBW children have approximately 13% higher annual OOPE spending for the OP visits related to selected CCHI compared to NBW children.

Examination of validity of identifying congenital heart disease from hospital discharge data without a gold standard: Using a data linkage approach

BACKGROUND

Administrative health data has been used extensively to examine congenital heart disease (CHD). However, the accuracy and completeness of these data must be assessed.

OBJECTIVES

To use data linkage of multiple administrative data sources to examine the validity of identifying CHD cases recorded in hospital discharge data.

METHODS

We identified all liveborn infants born 2013-2017 in New South Wales, Australia with a CHD diagnosis up to age one, recorded in hospital discharge data. Using record linkage to multiple data sources, the diagnosis of CHD was compared with five reference standards: (i) multiple hospital admissions containing CHD diagnosis; (ii) receiving a cardiac procedure; (iii) CHD diagnosis in the Register of Congenital Conditions; (iv) cardiac-related outpatient health service recorded; and/or (v) cardiac-related cause of death. Positive predictive values (PPV) comparing CHD diagnosis with the reference standards were estimated by CHD severity and for specific phenotypes.

RESULTS

Of 485,239 liveborn infants, there were 4043 infants with a CHD diagnosis identified in hospital discharge data (8.3 per 1000 live births). The PPV for any CHD identified in any of the five methods was 62.8% (95% confidence interval [CI] 60.9, 64.8), with PPV higher for severe CHD at 94.1% (95% CI 88.2, 100). Infant characteristics associated with higher PPVs included lower birthweight, presence of a syndrome or non-cardiac congenital anomaly, born to mothers aged <20 years and residing in disadvantaged areas.

CONCLUSION

Using data linkage of multiple datasets is a novel and cost-effective method to examine the validity of CHD diagnoses recorded in one dataset. These results can be incorporated into bias analyses in future studies of CHD.

[Telemedical Support of Feto-Neonatal Care in One Region - Part I: Demand Analysis Using the Example of East Saxony]

Excellence in feto-neonatal care forms the basis for health in adulthood and requires a collaboration of stakeholders in the health care system. As in other regions, demographic changes such as rural depopulation pose a risk to feto-neonatal care in Eastern Saxony. Areas in need of regional, perinatal collaboration have been identified: (I) multi-professional counselling of families with a suspected fetal disease, (II) immediately available expertise of a neonatologist during neonatal resuscitation, (III) evidence-based neonatal antibiotic therapy, (IV) backtransfer of extremely preterm infants or sick neonates, and (V) adequate psychosocial support of families with extremely preterm infants or sick neonates. Telemedicine enables regional partners to communicate efficiently and gives an audiovisual impression of the patient. The Saxony Center for feto/neonatal Health (SCFNH) collaborates with regional partners to establish a feto-neonatal telemedicine network "Sichere Geburt". The network will be scientifically evaluated and might be of help as a model for other regions with structural challenges.

[Telemedical support of feto-neonatal care in one region - Part II: Structural requirements and areas of application in neonatology]

Telemedical infrastructure for patient assessment, care and follow-up as well as interdisciplinary exchange can contribute to ensuring patient care that is close to home and meets the highest quality standards, even outside specialised centres. In neonatology, synchronous audio-visual communication across institutions has been used for many years, especially in the Anglo-American countries. Areas of application include extended neonatal primary care and resuscitation, specific diagnostic applications, e.g. ROP screening and echocardiography, as well as parental care, regular telemedical ward rounds and further training of medical staff, especially using simulation training. For the implementation of such telemedical infrastructures, certain organisational, medical-legal and technical requirements for hardware, software and structural and process organisation must be met. The concrete realisation of a telemedical infrastructure currently being implemented for the region of Eastern Saxony is demonstrated here using the example of the Saxony Center for feto/neonatal Health (SCFNH). Within the framework of feto-neonatal competence networks such as the SCFNH, the quality of medical care, patient safety and satisfaction in a region can be increased by means of a comprehensive, well-structured and established telemedical infrastructure.

Health Care Utilization in the First 7 Years in Children with Fetal Growth Abnormalities: A Retrospective Cohort Study

OBJECTIVE

To investigate the relationship between birth weight for gestational age and health care utilization of term offspring from birth to 7 years.

STUDY DESIGN

We used a population-based retrospective cohort study of infants (≥37 weeks' gestational age) born between 2003 and 2007 in the Canadian province of Nova Scotia (n = 42 050). Perinatal records were linked to provincial administrative health data from birth to age 7 years. The primary outcome was health care utilization (physician visits and hospital admissions) and costs. Birth weight was categorized as small for gestational age (SGA, <10th percentile), appropriate for gestational age (AGA), or large for gestational age (LGA, >90th percentile). Regression models adjusted for potential confounders were used to investigate the associations.

RESULTS

Children born SGA had a higher number of specialist visits and hospital admissions, a longer length of stay for the birth admission, and, as a result, higher physician and hospital costs amounting to a cost differential of Can $1222 during the first 7 years of life compared with children born AGA. By contrast, health care use and costs did not differ between children born LGA and AGA.

CONCLUSION

Former SGA term infants have a moderate increase in health care use and costs in early childhood compared with former AGA infants, and LGA birth at term is not associated with higher health care utilization.

The Association of Self-Reported Birthweight with Lung Function and Respiratory Diseases: Results from a Multi-Centre, Multi-Case Control Study in Italy

Early life conditions are associated with lung function and the development of respiratory and non-respiratory illnesses. The relationship with birthweight (BW), however, is conflicting. We examined associations of self-reported BW with lung function and the development of respiratory and also non-respiratory diseases within the GEIRD (Gene-Environment Interaction in Respiratory Diseases) project, an Italian multi-centre, multi-case control study involving cases of COPD, asthma, allergic rhinitis and controls. Multinomial logistic regression was performed with case/control status as response variable; BW as main determinant; and adjusting for sex, age and smoking status. Of the 2287 participants reporting BW, 6.4% (n = 147) had low BW (<2500 g), and this proportion was greater in women than men (7.8% vs. 5.1%; p = 0.006). Both men and women with low BW were shorter than those with normal BW (mean ± SD: 160.2 ± 5.5 vs. 162.6 ± 6.5 cm in women, p = 0.009; 172.4 ± 6.1 vs. 174.8 ± 7.2 cm in men, p < 0.001). Although FEV1 and FVC were reduced in individuals with low BW, this was explained by associations with sex and height. In multivariable analysis, BW was not associated with respiratory diseases in adulthood. However, those with low BW had a higher risk of self-reported hospitalisation for lung disease before the age of two (10.3% vs. 4.1%; p < 0.001), severe respiratory infection before the age of five (16.9% vs. 8.8%; p = 0.001) and hypertension in adulthood (29.9% vs. 23.7%; p = 0.001); however, they had a lower risk of arrhythmia (2.7% vs. 5.8%; p = 0.027).

Perinatal outcome of babies born after using a simplified IVF culture system versus ICSI with sibling oocytes: a prospective cohort study

RESEARCH QUESTION

Is there a difference in perinatal outcome in the same patient cohort for babies conceived following randomization of sibling oocytes allocated to a simplified IVF culture system (SCS) or intracytoplasmic sperm injection (ICSI) followed by conventional culturing?

DESIGN

The study compared the perinatal outcomes of 367 babies born from 1 January 2013 until 31 December 2020 after using split SCS and ICSI insemination of sibling oocytes in a selected group of normo-responsive women, excluding cases of severe male infertility. Primary outcome measures were preterm birth (PTB; <37 weeks' gestation), low birthweight (LBW; <2.5 kg) and small for gestational age (SGA) as a primary outcome parameter while secondary outcome measures included mean birthweight, mean gestational age, extreme prematurity (<32 weeks), very low birthweight (<1.5 kg), perinatal mortality, multiple pregnancy and Caesarean section rate.

RESULTS

A total of 105 and 103 singleton babies were born after fresh embryo transfer (FRET) and 71 and 50 singletons after frozen embryo transfer (FET) in the SCS and ICSI groups, respectively. For babies born after FRET, the LBW rate was 2.9% (3/105) for SCS and 7.8% (8/103) for ICSI (P = 0.10). LBW occurred in 4.2% (3/71) and 0% (0/50) of babies born after the transfer of cryopreserved-thawed SCS and ICSI embryos, respectively (P = 0.14). The rate of PTB was 3.8% and 6.8% for SCS and ICSI in FRET cycles (P = 0.33), and 8.5% and 6.0% for SCS and ICSI in FET cycles (P = 0.62). One congenital malformation was found in the SCS FET group.

CONCLUSION

There was no difference in perinatal outcome for singleton and twin babies born after SCS and ICSI.

Perinatal Hyperoxia and Developmental Consequences on the Lung-Brain Axis

Approximately 11.1% of all newborns worldwide are born preterm. Improved neonatal intensive care significantly increased survival rates over the last decades but failed to reduce the risk for the development of chronic lung disease (i.e., bronchopulmonary dysplasia (BPD)) and impaired neurodevelopment (i.e., encephalopathy of prematurity (EoP)), two major long-term sequelae of prematurity. Premature infants are exposed to relative hyperoxia, when compared to physiological in-utero conditions and, if needed to additional therapeutic oxygen supplementation. Both are associated with an increased risk for impaired organ development. Since the detrimental effects of hyperoxia on the immature retina are known for many years, lung and brain have come into focus in the last decade. Hyperoxia-induced excessive production of reactive oxygen species leading to oxidative stress and inflammation contribute to pulmonary growth restriction and abnormal neurodevelopment, including myelination deficits. Despite a large body of studies, which unraveled important pathophysiological mechanisms for both organs at risk, the majority focused exclusively either on lung or on brain injury. However, considering that preterm infants suffering from BPD are at higher risk for poor neurodevelopmental outcome, an interaction between both organs seems plausible. This review summarizes recent findings regarding mechanisms of hyperoxia-induced neonatal lung and brain injury. We will discuss common pathophysiological pathways, which potentially link both injured organ systems. Furthermore, promises and needs of currently suggested therapies, including pharmacological and regenerative cell-based treatments for BPD and EoP, will be emphasized. Limited therapeutic approaches highlight the urgent need for a better understanding of the mechanisms underlying detrimental effects of hyperoxia on the lung-brain axis in order to pave the way for the development of novel multimodal therapies, ideally targeting both severe preterm birth-associated complications.

[Maternal periodontitis and low birth weight: systematic review and meta-analysis]

Recent evidence points to the influence of periodontal inflammatory processes on the occurrence of low birth weight. Although many studies employed robust investigation methods, there is still no general agreement on the relationship between maternal periodontitis and low birth weight. The search for studies was conducted until April 2019. The studies included cohort and case-control studies that estimated the association between periodontitis and low birth weight, with no restriction on language or date of publication. Analysis of the heterogeneity of studies, subgroup analyses and meta-analyses with a random effects model were performed. Summary association measurements were estimated using the crude and adjusted Odds Ratio, with respective 95% confidence intervals. Visual inspection of graphs was used to assess publication bias. A total of 21 articles were identified, all of which were selected for the meta-analysis. The final model indicates that periodontitis in pregnant women was associated with low birth weight (ORgross=2.13; CI95%=1.60-2.83; I2=80.0% and ORadjusted=2.64; CI95%=2.04-3.42; I2=17.4%). Pregnant women with periodontitis may be more than twice as likely to have low birth weight babies.

Impact of an integrated mother-preterm infant intervention on birth hospitalization charges

OBJECTIVE

To examine whether the H-HOPE (Hospital to Home: Optimizing the Preterm Infant's Environment) intervention reduced birth hospitalization charges yielding net savings after adjusting for intervention costs.

STUDY DESIGN

One hundred and twenty-one mother-preterm infant dyads randomized to H-HOPE or a control group had birth hospitalization data. Neonatal intensive care unit costs were based on billing charges. Linear regression, propensity scoring and regression analyses were used to describe charge differences.

RESULTS

Mean H-HOPE charges were $10,185 lower than controls (p = 0.012). Propensity score matching showed the largest savings of $14,656 (p = 0.003) for H-HOPE infants, and quantile regression showed a savings of $13,222 at the 75th percentile (p = 0.015) for H-HOPE infants. Cost savings increased as hospital charges increased. The mean intervention cost was $680 per infant.

CONCLUSIONS

Lower birth hospitalization charges and the net cost savings of H-HOPE infants support implementation of H-HOPE as the standard of care for preterm infants.
