OBJECTIVES: Low birth weight (LBW) is one of the major factors affecting child morbidity and mortality worldwide. Every day, approximately 800 women die from causes related to pregnancy and childbirth worldwide. Maternal ill health increases the risk of LBW. This study seeks to investigate determinants and incidence of LBW. METHODS: This study was conducted based on the medical records of mothers and their 1,946 infants born in 2016-2019 at the Department of Gynaecology and Obstetrics of Louis Pasteur University Hospital in Košice. Data on mothers and newborn infants were obtained from the Reports on mothers at childbirth. The inclusion criteria were singleton births and birth weight > 500 g. The exclusion criteria were twins or multiple births, congenital anomalies and stillbirths, birth weight ≥ 4,000 g or ≤ 500 g, and Roma ethnicity. Roma children are more likely to be born prematurely, with low birth weight. Roma mothers have different lifestyle. Univariate analysis was employed to evaluate the association between the independent variables and LBW. Variables that were found to be statistically significant were then further analysed using multivariable logistic analysis for each dependent variable. The implementation of the research was approved by the Ethics Committee. RESULTS: Of 1,946 newborns, 271 (13.90%) have low birth weight. The mean of birth weight at delivery was 3,068.62 (SD 671.16) grams. Factors that were associated with LBW were primary maternal education (OR = 2.98, 95% CI: 1.08-8.21, p = 0.034), marital status single (OR = 2.88, 95% CI: 1.68-4.94, p < 0.001), number of prenatal care visits less than 8 (OR = 1.62, 95% CI: 1.01-2.61, p = 0.047), and preterm birth (OR = 74.94, 95% CI: 45.44-123.61, p < 0.001). CONCLUSION: The reducing of LBW requires strategies to improve maternal lifestyle, maternal care before, during and after birth and to strengthen social support.

OBJECTIVE: This study analyses the differences in birth outcomes between Roma and non-Roma mothers and investigates the potential causes of such differences. METHODS: We conducted a retrospective cohort study of 1,989 non-Roma and 799 Roma mothers who gave birth in 2014 and 2015 at the Gynaecology and Obstetrics Clinic of Louis Pasteur University Hospital in Košice. Data on mothers and new-born infants have been obtained from the birth book and from the reports on mothers at childbirth. For low birth weight we considered the weight of a new-born weighing less than 2,500 grams and as for premature birth we referred to childbirth before pregnancy week 37. The file was split by ethnicity and statistically processed in IBM SPSS Statistics 21.0. RESULTS: Our results confirmed a lower birth weight among Roma children (-365.4 grams, p < 0.001). The shorter gestation age and higher risk of premature birth were not statistically significant regarding Roma children. Based on the characteristics of Roma mothers, they are at higher risk of giving birth as minor (OR = 23.64; 95% CI = 15.29-36.54; p < 0.001), as single mothers (OR = 7.13; 95% CI = 5.80-8.76; p < 0.001), with basic education or lack of education (OR = 141.31; 95% CI = 100.47-198.76; p < 0.001). They also have a higher risk of smoking during pregnancy (OR = 23.84; 95% CI = 18.06-31.49; p < 0.001); drinking alcohol (OR = 11.71; 95% CI = 3.36-40.90; p < 0.001) and taking drugs (OR = 8.70; 95% CI = 1.81-42.02; p < 0.001). Roma women attended gynaecologists more rarely. CONCLUSION: It is therefore important to support the work of community health workers and stimulate collaboration between community health professionals, paediatricians and gynaecologists to overcome institutional barriers in maternity and child care for mothers living in Roma settlement.

BACKGROUND: Health problems of premature infants can affect both general and oral health. The enamel defects, poor dietary and oral hygiene habits may predispose these children to dental caries. This study was conducted to assess the impact of very low birth weight and prematurity on caries risk in early childhood. METHODS: The study cohort consists of 189 of one year old infants. Anamnestic data were obtained from hospital records, feeding practice, bed-time sugar drinks and oral hygiene onset from questionnaires. Saliva samples of children and their mothers were collected for the detection of cariogenic pathogens. RESULTS: VLBW newborns had significantly shorter gestation age (29.6 vs. 38.8)) and lower mean birthweight (1124 g vs 3315 g) compared to NBW ones (p < 0.0001). Statistical significance has been found in the presence of early morbidity (p < 0.0001) and regular medication intake (p = 0.007). VLBW children got more frequently sweetened drinks during the day and night (p = 0.007). Regular oral hygiene practice was more frequent in full term group (p = 0.002). There was statistical difference in the presence of enamel hypoplasia in VLBW children (p = 0.033) but no statistical difference in the presence of hypomineralization (p = 0.0736) in comparison to NBW individuals. Proportional representation and count of S. mutans did not reveal statistical difference neither in both groups of children (p = 0.484) nor in both groups of mothers (p = 0.385). CONCLUSIONS: The study confirmed anamnestic and medical differences between both groups. The proportional representation and count of S. mutans did not reveal statistical difference neither in VLBW and NBW children, nor in their mothers.

BACKGROUND: Peripherally inserted central catheters (PICCs) are used to administer parenteral nutrition (PN) in very low birth weight infants (VLBW; <1500 g). Clinicians try to optimize early nutrition but also minimize the risks associated with intravascular devices. The objective of this study was to examine the early nutrition impact of discontinuing PN at different enteral feed volumes in VLBW infants. METHODS: In this unmasked, multicenter, randomized controlled trial, patients were randomly assigned to PICC removal and PN discontinuation at an enteral feed volume of 100 mL/kg/day (intervention) or 140 mL/kg/day (control). Clinically stable VLBW infants with a PICC in situ who were receiving PN were eligible for inclusion. Infants with major congenital anomalies were excluded. A total of 139 patients were enrolled; 69 and 70 patients were randomized to the intervention and control groups, respectively. The primary outcome measure was the mean difference in time (days) to regain birth weight. RESULTS: The groups were well matched at study entry. Patients in the intervention group regained birth weight more slowly (mean difference 1.5 days CI: 0.3-2.7 days, P = 0.01). The mean difference in time to regain birth weight for infants <1000 g was 2.8 days (95% CI: 0.8-4.8 days, P = 0.008). CONCLUSIONS: In VLBW infants, early PICC removal at an enteral feed volume of 100 mL/kg/day compared with later removal at 140 mL/kg/day resulted in a significant delay in time to regain birth weight, and this delay was more pronounced in infants <1000 g.

BACKGROUND There is a high prevalence of cognitive and socioemotional dysfunction in very low birth weight (VLBW <1500 g) and extremely low birth weight (ELBW <1000 g) children. This study from the Czech Republic aimed to compare the cognitive and socioemotional development at 5 and 9 years of age of children born with VLBW/ELBW with children born with normal birth weight (NBW ≥2500 g). MATERIAL AND METHODS The clinical group consisted of 118 VLBW/ELBW children and the control group consisted of 101 children with NBW at ages 5 to 9 years. The research battery included selected subscales from the Intelligence and Development Scales (IDS), A Developmental Neuropsychological Assessment - second edition (NEPSY-II), and the Behavior Rating Inventory of Executive Function (BRIEF). Data were analyzed using STATA IC v. 15 software and G*Power (descriptive statistic, analysis of variance (ANOVA), correlations, multivariate analysis of variance - MANOVA, post hoc power analysis). RESULTS We found a statistically significant difference in cognitive and socioemotional development between children with VLBW/ELBW and those with NBW. The average intelligence quotient (IQ) of VLBW/ELBW children was 96.38, while that of NBW children was 12.98 points higher (P<0.001). NBW children achieved better results on all subtests of the IDS (P<0.001) as well as in affect recognition (P<0.001). All results for both groups were within normal range. Parents of VLBW/ELBW children did not recognize impaired executive functioning (P=0.494). CONCLUSIONS This study has shown significant cognitive and socioemotional deficit in children born with VLBW and ELBW when evaluated at 5 and 9 years of age.

BACKGROUND: Toxoplasma gondii, one of the most common parasites, causes toxoplasmosis, one of the most frequent zoonotic diseases worldwide. T. gondii infects about one-third of the world's population. T. gondii infection is generally considered a major risk for spontaneous abortion, prematurity and low birth weight in the animal sphere. Less commonly, a toxoplasma serological profile is correlated with the particular data of delivery. Acute T. gondii infection during pregnancy often leads to spontaneous abortion and/or a severe injury of the eyes, brain, and other structures of the foetus. Latent T. gondii infection of pregnant women could lead to less obvious but important changes during pregnancy, including the end product of pregnancy and the timing of labour. This study aimed to contribute to the current knowledge by comparing serological T. gondii profiles of pregnant women with prematurity and low birth weights of newborns. MATERIAL AND METHODS: A retrospective study design was adopted. The study participants included a cohort of 1733 pregnant women who consecutively gave birth to their children and underwent regular antenatal biochemical screening between the 14th and 16th weeks of pregnancy. Prematurity was defined as the liveborn preterm delivery in gestational age of pregnancy <37 weeks. Low birth weight was defined as weight at birth of ≤2499 grams. The complement-fixation test (CFT) provided serological profiles for toxoplasmosis that expresses the overall levels of toxoplasma immunoglobulins of all classes. Enzyme-linked immunosorbent assay (ELISA) tests for IgG and IgM were used simultaneously. IgM positivity helped to differentiate acute from the latent stage of toxoplasmosis. Birth data, especially the week of delivery and fetal weight, were evaluated accordingly. RESULTS: Of the 1733 pregnant women, 25% were diagnosed as latent toxoplasma positive, and 75% as toxoplasma negative. There were 87 premature deliveries versus 1646 timely births. We observed 88 low birth weights and 1645 normal fetal weights. We found a statistically significant association between latent toxoplasmosis and prematurity, χ2(1) = 5.471, p = .019 and between latent toxoplasmosis and low birth weight of newborns, χ2(1) = 7.663, p = .006. There was a 1.707 times higher risk of prematurity for toxoplasma-positive women, while the risk for low birth weight was 1.861 times higher. The strength of both tests of association was mild. We tested the correlation between the levels of CFT titres and week of delivery and weight of newborns. No association was found between the level of latent toxoplasmosis and the week of delivery and fetal weight. CONCLUSION: Latent toxoplasmosis was associated with premature birth rate and lower birth weight of newborns. The odds of premature delivery was 1.7 and low birth weight 1.9 times higher in women with latent toxoplasmosis compared to toxoplasma negative women. Even though the strength of the association in our large sample is relatively mild, the combination of latent toxoplasmosis with other adverse factors could cause serious harm. Whole CFT and specific IgG levels of latent toxoplasmosis are not linked to the severity of prematurity or low birth weight in newborns.

BACKGROUND: Many studies have demonstrated the association between low birth weight (LBW) and chronic kidney disease, estimated glomerular filtration rate (eGFR) and kidney volume (KV). However, studies on twins and those investigating numerous perinatal factors beyond LBW, and their associations with various kidney parameters are scarce. METHODS: A two-center cross-sectional study on five-year-old LBW children was conducted between 2021 and 2023. 110 children were enrolled (8 LBW, 58 very LBW (VLBW), 44 extremely LBW (ELBW)); 56 were twins. We examined associations between birth weight (BW), various prenatal, perinatal and postnatal factors, and eGFR, KV, tubular abnormalities and kidney ultrasound abnormalities, both in singletons and twins. RESULTS: In children with ELBW, eGFR correlated with BW (r = 0.55, P = 0.0018), while in those with BW ≥ 1000 g, eGFR remained constant. Other factors associated with decreased eGFR were hypertensive disorder of pregnancy (93.86 vs. 87.26 ml/min/1.73m2, P = 0.0285) in singletons, decreased growth velocity (β = 0.83, P = 0.0277) in twins, and lower total KV (tKV) and relative KV (rKV) in both singletons (r = 0.60, P < 0.0001 for tKV and r = 0.45, P = 0.0010 for rKV) and twins (β = 0.34, P < 0.0001 for tKV and β = 0.23, P = 0.0002 for rKV). Based on the multivariable models excluding KV, BW and gestational age were associated with eGFR in singletons, while male gender, BW, growth velocity, and coffee drinking during pregnancy were associated with eGFR in twins. However, in models that included KV, BW, gestational age and growth velocity were no longer significant. Total KV was associated with BW (r = 0.39, P = 0.0050 for singletons; β = 2.85, P < 0.0001 for twins), body mass index (r = 0.34, P = 0.0145 for singletons; β = 8.44, P < 0.0001 for twins), and growth velocity (β = 1.43, P = 0.0078). Twins born small for gestational age had lower tKV (70.88 vs 89.20 ml, P < 0.0001). Relative KV showed similar associations. Relative kidney volumes were significantly lower for both kidneys compared to the reference population (55.02 vs 65.42 ml/m2, P < 0.0001 for right kidney and 61.12 vs 66.25 ml/m2, P = 0.0015 for left kidney); however, only 8.6% of children had rKV below 10th percentile. CONCLUSION: Many factors affect eGFR and KV, some of them differ between twins and singletons. Based on multivariable models, eGFR seems to be better predicted by KV than by BW and gestational age in LBW children. Relative kidney volumes were significantly lower in our cohort compared to the reference population, but only 8.6% of rKV were below 10th percentile.

This study tested the hypothesis, suggested by several recent reports, that air pollution may increase the risk of adverse birth outcomes. This study analyzed all singleton live births registered by the Czech national birth register in 1991 in 67 districts where at least one pollutant was monitored in 1990-1991 (n = 108,173). Maternal exposures to sulfur dioxide (SO(2)), total suspended particles (TSP), and nitrous oxides (NO(x)) in each trimester of pregnancy were estimated as the arithmetic means of all daily measurements taken by all monitors in the district of birth of each infant. Odds ratios of low birth weight (< 2,500 g), prematurity (< 37 weeks of gestation), and intrauterine growth retardation (IUGR; < 10th percentile of birth weight for gestational age and sex) were estimated by robust logistic regression. The median (and 25th and 75th percentile) trimester exposures were 32 (18, 56) microg/m(3) for SO(2); 72 (55, 87) microg/m(3) for TSP; and 38 (23, 59) microg/m(3) for NO(x). Low birth weight (prevalence 5.2%) and prematurity (prevalence 4.8%) were associated with SO(2) and somewhat less strongly with TSP. IUGR was not associated with any pollutant. The effects on low birth weight and prematurity were marginally stronger for exposures in the first trimester, and were not attenuated at all by adjustment for socioeconomic factors or the month of birth. Adjusted odds ratios of low birth weight were 1.20 [95% confidence interval (CI), 1.11-1.30] and 1.15 (CI, 1.07-1.24) for a 50 microg/m(3) increase in SO(2) and TSP, respectively, in the first trimester; adjusted odds ratios of prematurity were 1.27 (CI, 1.16-1.39) and 1.18 (CI, 1.05-1.31) for a 50 microg/m(3) increase in SO(2) and TSP, respectively, in the first trimester. Low gestational age accounted for the association between SO(2) and low birth weight. These findings provide further support for the hypothesis that air pollution can affect the outcome of pregnancy.

This review article describes the scientific evidence for the relationship between birth weight and insulin resistance. Most studies demonstrate that low birth weight is closely connected to insulin resistance and later development of diabetes type II in adulthood. For this reason it is important for clinicians to focus on the personal history of the patient's birth weight. In patients with low birth weight, primary measures should be taken to prevent the development or progress of insulin resistance, and late consequences like diabetes and atherosclerotic complications.

BACKGROUND: Treatment of the patent ductus arteriosus (PDA) in the preterm infant remains contentious. There are numerous options of the PDA management from early targeted treatment, late (symptomatic) treatment to no treatment at all. AIMS: To evaluate a three different PDA management approaches in very low birth weight (VLBW) infants. STUDY DESIGN: A retrospective observational time series study of three cohorts of VLBW infants born between 2004 and 2011. SUBJECTS: Infants in Symptomatic Treatment Group (STG) were echocardiographically evaluated when clinical signs suggestive of a PDA were present and treated if a haemodynamically significant PDA was confirmed. Early Targeted Group (ETG) underwent echocardiography within the first 48h and infants received ibuprofen if a large PDA was present. Conservative Treatment Group (CTG) was screened by echocardiography on day seven of life; patients with PDA were managed with increased positive end expiratory pressure and fluid restriction as a first line intervention. OUTCOMES: The primary outcome was medical and surgical treatment in the three time periods. Secondary outcomes included mortality, severe periventricular and intraventricular haemorrhage, respiratory distress syndrome and chronic lung disease. RESULTS: There were 138 infants diagnosed with PDA; 52 infants in STG, 52 infants in ETG and 34 infants in CTG. Ibuprofen therapy and ligation were less frequent in CTG. There was significantly decreased incidence of chronic lung disease in CTG compared to STG (18% vs. 51%; p=0.003) and to ETG (18% vs. 46%; p=0.02). There was no difference in the other short term outcomes. CONCLUSION: Conservative treatment of persistent ductus arteriosus in VLBW infants is a feasible option and future randomized trials of conservative management are warranted.
