A "mikveh" is a pool of water for ritual immersion by Jewish women. It had been reported to be a risk factor for GBS colonization. Objective: To determine whether there is an association between ritual immersion in the mikveh pools and GBS carriership. Methods: Water samples and bacterial swabs were taken from eight mikveh pools centers at two separate occasions and tested for GBS growth. For determination of the total number of live, aerobic bacteria, each sample was grown on strep selective agar for 48 hours at 37˚C and CO 2 5%. Results: All the samples were tested. No trace of GBS was found in any of the samples. Conclusions: The findings of this study refute earlier findings and suggest that there is no association between ritual immersion in mikvehs and GBS carriership.

Aim: To investigate the adhesion and aggregation of platelets from preterm infants on ECM under defined shear conditions. Methods: In vitro platelet function was investigated in 106 preterm infants, 74 full term infants, and 26 healthy adults. Blood samples were obtained from all infants within 24 hours of birth, and weekly until discharge from preterm infants only. Citrated whole blood was placed in ECM precoated tissue culture plates and subjected to shear stress (1300 s −1) for two minutes using a rotating Teflon cone. Platelet adhesion (surface coverage) and aggregation (average size) to ECM were assayed using an image analyser. Assays for von Willebrand factor (vWF) antigen, ristocetin cofactor, and vWF collagen-binding activity were performed on samples from an additional 70 preterm infants, 23 healthy full term infants, and 24 healthy adults. Preterm infants with hyaline membrane disease (HMD) were analysed separately in both cohorts. Results: Platelets from preterm infants displayed significantly less platelet adhesion than those from full term infants but similar aggregation and levels of vWF antigen, ristocetin cofactor, and collagen binding activity. Mean surface coverage was 22.0 (8.4)% for preterm infants with HMD, 28.7 (8.0)% for healthy preterm infants, and 35.7 (7.9)% for full term infants. Surface coverage in the preterm infants correlated with gestational age during the first 24 hours only, and did not reach full term levels during 10 weeks of follow up. Conclusion: Platelet adhesion to ECM is significantly poorer in preterm than in full term infants, and poorer in preterm infants with HMD than in healthy preterm infants. Intrinsic platelet properties rather than the concentration or activity of vWF may be responsible for this difference.

Neonatal outcomes including birth weight, Apgar score, retinopathy of prematurity, intraventricular hemorrhage, bronchopulmonary dysplasia, necrotizing enterocolitis, hearing impairment and mortality were evaluated.Results: Ninety four preterm infants who were born after a prolonged premature rupture of membranes of at least 7 days were included in the study.Median gestational week at onset of membrane rupture was 27.1 ± 4.2 weeks (range 17 - 33) and median latency period in days was 16 ± 21.8 (range 7 - 105). We found that the survival rate to discharge within neonates born after prolonged rupture of membrane at gestational week less than 24 weeks is 79.2%. These neonates d...

We included 58 004 infants born weighing <1500 g at 24(0)-31(6) weeks' gestation from databases in Australia/New Zealand, Canada, Israel, Japan, Spain, Sweden, Switzerland, and the United Kingdom. We compared a composite outcome (mortality or any of grade ≥3 peri-intraventricular hemorrhage, periventricular echodensity/echolucency, bronchopulmonary dysplasia, or treated retinopathy of prematurity) between each country and all others by using standardized ratios and pairwise using logistic regression analyses. Despite differences in population coverage, included neonates were similar at baseline. Composite outcome rates varied from 26% to 42%. The overall mortality rate before discharge was 10% (range: 5% [Japan]-17% [Spain]). The standardized ratio (99% CIs) estimates for the composite out...

Mothers with gestational diabetes were encouraged to breastfeed their infants immediately after birth in the delivery room. The breastfeeding duration was recorded by the midwife. The longer duration of breastfeeding subgroup (n = 39) demonstrated a lower rate of hypoglycaemia in the first 8 hours of life (&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 40 mg/dl) compared to the shorter duration subgroup (n = 40), but this difference did not reach statistical significance (2.6% vs. 17.5% respectively, p = 0.057). Hypoglycaemia was mainly predicted by lower cord glucose for each decrease of 10 mg/dl (OR 2.11 [CI 1.1-4.03] p = 0.024. Longer duration of delivery room breastfeeding did not reduce the rate of hypoglycaemia, which was mainly influenced by lower cord blood glucose level.

The objective was to determine the significance of severe congenital heart defects (CHDs) for these risks. Methods and Results This cohort study included infants from 10 countries born from 2007-2015 at 24 to 31 weeks' gestation with birth weights <1500 g. Severe CHDs were defined by International Classification of Diseases, Ninth Revision (ICD-9) and Tenth (ICD-10) codes and categorized as those compromising systemic output, causing sustained cyanosis, or resulting in congestive heart failure. The primary outcome was in-hospital mortality. Secondary outcomes were neonatal brain injury, necrotizing enterocolitis, bronchopulmonary dysplasia, and retinopathy of prematurity. Adjusted and propensity score-matched odds ratios (ORs) were calculated. Analyses were stratified by type of CHD, gestational age, and network. A total of 609 (0.77%) infants had severe CHD and 76 371 without any malformation served as controls. The mean gestational age and birth weight were 27.8 weeks and 1018 g, respectively. The mortality rate was 18.6% in infants with CHD and 8.9% in controls (propensity score-matched OR, 2.30; 95% CI, 1.61-3.27). Severe CHD was not associated with neonatal brain injury, necrotizing enterocolitis, or retinopathy of prematurity, whereas the OR for bronchopulmonary dysplasia increased. Mortality was higher in all types, with the highest propensity score-matched OR (4.96; 95% CI, 2.11-11.7) for CHD causing congestive heart failure. While mortality did not differ between groups at <27 weeks' gestational age, adjusted OR for mortality in infants with CHD increased to 10.9 (95% CI, 5.76-20.70) at 31 weeks' gestational age. Rates of CHD and mortality differed significantly between networks. Conclusions Severe CHD is associated with significantly increased mortality in very preterm infants.

To evaluate the contribution of targeted saliva screening for cCMV to the detection of infants born with cCMV-related SNHL who failed universal newborn hearing screening (UNHS). We retrospectively reviewed the audiological and medical records of infants who failed UNHS and were tested for cCMV using saliva sample prior to discharge at Sheba Medical Center between 2014 and 2015. Positive cases were confirmed by urine sample. Two hundred (1%) of the 19 830 infants tested during the study period failed in-hospital hearing screening. A saliva specimen was obtained prior to discharge in 187 infants (93.5% of those who failed UNHS). In 178 infants saliva testing was performed at ≤21 days of chronological age and yielded results. cCMV infection was identified in 4/178 tested infants (2.25%, 95% CI 0.8% to 5.3%), of whom three were diagnosed with SNHL (1.7%, 95% CI 0.5% to 4.4%) and offered antiviral treatment. Two of the tested infants (1.12%, 95% CI 0.2% to 3.6%) were diagnosed with cCMV solely due to failure in UNHS. Occult central nervous system (CNS) symptoms of cCMV infection were detected in 2/4 infants following targeted investigation. Targeted cCMV screening in newborns who failed UNHS contributed to the early detection of infants born with cCMV-related isolated SNHL or with occult CNS symptoms who could potentially benefit from antiviral treatment.

An observational study was performed on data of the Israel Neonatal Network linked together with the Maccabi Healthcare Services medical records. After discharge from the neonatal intensive care unit, 6385 infants of very low birth weight born from 1995 to 2012 were registered with Maccabi Healthcare Services and formed the study cohort. Multivariable negative binomial regression models were calculated to estimate the adjusted relative risk (aRR) and 95% CI for hospitalization. Up to 18 years following discharge, 3956 infants were hospitalized at least once. The median age of follow-up was 10.7 years with total of follow-up of 67 454 patient years and 10 895 hospitalizations. The risks for rehospitalization were increased significantly for each of the neonatal morbidities: surgical necrotizing enterocolitis (NEC), aRR 2.71 (95% CI 2.08-3....

The education period did not influence the ordering of partial thromboplastin time tests, despite a significant posteducational change in surgeons' attitudes. In contrast, administrative restriction of coagulation test orders led to a 50% decline on four of the five study wards. We conclude that an educational intervention followed by administrative restriction may be considered an acceptable means of overcoming clinician reluctance to change well-established but redundant clinical policy.

Retrospective cohort. Tertiary university-affiliated medical centre. All newborns of low-risk singleton pregnancies born at 39+0 to 44+0 weeks&amp;#39; gestation over a 5-year period. multiple gestation, maternal hypertensive disorder, diabetes or cholestasis, placental abruption or intrapartum fever (&amp;gt;38°C), small for gestational age (&amp;lt;10th centile) and major congenital or chromosomal anomalies. None. Admission to the neonatal intensive care unit (NICU), hospital length of stay, 5-min Apgar score, birth trauma, respiratory, neurological, metabolic and infectious morbidities and neonatal mortality. The adverse outcome rate was compared among three groups based on gestational age at birth: post-term (≥42+0 weeks), late term (41+0 to 41+6 weeks) and full term (39+0 to 40+6 weeks). Of the 23 524 eligible neonates, 747 (3.2%) were born post-term, 4632 (19.7%) late term and 18 145 (77.1%) full term. Women in the post-term group versus the late-term group had a significantly higher rate of caesarean section (8.9% vs 5.6%, p&amp;lt;0.001) and operative vaginal delivery (9.6% vs 7.4%, p=0.024). Post-term pregnancy versus full-term pregnancy was associated with an increased risk of NICU admission (OR 2.0, 95% CI 1.4 to 2.8), respiratory morbidity (OR 2.2, 95% CI 1.3 to 3.8) and infectious morbidity (OR 1.88, 95% CI 1.32 to 2.69). Post-term pregnancy versus late-term pregnancy was similarly associated with an increased risk of NICU admission (OR 2.0, 95% CI 1.4 to 2.9), respiratory morbidity (OR 2.7, 95% CI 1.5 to 5.0) and infectious morbidity (OR 1.8, 95% CI 1.2 to 2.7) and with hypoglycaemia (OR 2.6, 95% CI 1.2 to 5.4). Post-term delivery was not associated with neonatal mortality. Post-term pregnancy is an independent risk factor for neonatal morbidity even in low-risk singleton pregnancies.

A retrospective cohort study design was used. The study group included all low-risk singleton term (37 + 0 to 41 + 6 weeks) newborns delivered in a single tertiary university-affiliated medical center over a 5-year period. Outcome of neonates delivered at 37 + 0 to 37 + 6 weeks of gestation (early term) and 41 + 0 to 41 + 6 weeks of gestation (late term) was compared to that of neonates delivered at 39 + 0-39 + 6 weeks of gestation (control). Overall, the outcome of 30 229 neonates was analyzed. The incidence of neonatal mortality was 1.0 per 1000 live-born neonates, with no significant difference between the various gestational age groups. Early term newborns were at higher risk for respiratory morbidity, hypoglycemia, hypocalcemia, thrombocytopenia and unexplained jaundice, and had higher rates of prolonged hospital stay, NICU admission, sep...

Neonates were to be placed in a protective infant carrier (PIC) or an improved PIC ("active PIC") to which filtered air was actively introduced by a blower. The specific needs of low birthweight babies hospitalized in intensive care units and treated in incubators were not adequately addressed. Transfer to a PIC meant disconnecting the infants from life-supporting systems and monitoring devices and exposing them to changes in ambient temperature. To overcome this difficulty the original incubator was used as a CW protective device. Its ports were sealed and low-grade positive pressure was created. This avoided transfer of the neonates from their controlled environment, reduced physiological stress, and improved medical supervision.

In a retrospective study, neonates born to mothers with intrapartum fever, (≥ 37.8°C), were compared to control group matched by gestational age and birthweight. Overall, 159 singleton full term neonates born to women with intrapartum fever (study group) were compared to 159 control infants. No differences in neonatal outcomes were found between the two groups except for a higher rate of meconium-stained amniotic fluid in the maternal-fever group. There were no cases of neonatal infection, severe neonatal morbidity, or neonatal mortality in either of the groups. Full sepsis workup and intravenous antibiotic treatment were provided to 17.6% of the neonates in the study group. Logistic regression analysis revealed that delivery by Cesarean section was the only factor independently associated with the decision to perform a full sepsis work up and antibiotic treatment in cases of maternal intrapartum fever (OR 32.0, 95% CI 9.4-112.1). In low-risk women with asymptomatic intrapartum fever, neonatal infection is uncommon, so that aggressive evaluation and management of these infants may not be necessary and should be balanced against the low risk of neonatal sepsis.

We aimed to identify risk factors for BT and to evaluate the effect of BT on short-term neonatal outcome. A retrospective, cohort, case-control study of all cases of BT in a single tertiary center (1986-2009). The control group included the two subsequent full-term singleton neonates who did not experienced BT. Short-term neonatal outcome was compared between the groups including Apgar scores, NICU admission, duration of hospitalization and neurologic, respiratory and metabolic morbidity. Of the 118 280 singleton full-term newborns delivered during the study period, 2874 were diagnosed with BT (24.3/1000). The most frequent types of BT were scalp injuries (63.9%, 15.5/1000) and clavicular fracture (32.1%, 7.7/1000). The following factors were found to be independent risk factors for BT: instrumental delivery (OR 7.5, 95% CI 6.3-8.9), birth weight, delivery during risk hours, parity, maternal age and neonatal head circumference. Cesarean delivery was the only factor protective of BT (OR 0.2, 95% CI 0.2-0.3). Neonates in the study group had a prolonged length of hospital stay (3.3 versus 2.7 d, p = 0.001), were more likely to be admitted to the NICU (3.9% versus 1.9%, p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001), and had a higher rate of jaundice (11.9% versus 7.1%, p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001) and neurological morbidity (4.7% versus 2.3%, p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001). Instrumental delivery appears to be responsible for most cases of neonatal BT.

Conclusion: Platelet adhesion to ECM is significantly poorer in preterm than in full term infants, and poorer in preterm infants with HMD than in healthy preterm infants. Intrinsic platelet properties rather than the concentration or activity of vWF may be responsible for this difference.

The objective was to determine the significance of severe congenital heart defects (CHDs) for these risks. Methods and Results This cohort study included infants from 10 countries born from 2007-2015 at 24 to 31 weeks' gestation with birth weights <1500 g. Severe CHDs were defined by International Classification of Diseases, Ninth Revision (ICD-9) and Tenth (ICD-10) codes and categorized as those compromising systemic output, causing sustained cyanosis, or resulting in congestive heart failure. The primary outcome was in-hospital mortality. Secondary outcomes were neonatal brain injury, necrotizing enterocolitis, bronchopulmonary dysplasia, and retinopathy of prematurity. Adjusted and propensity score-matched odds ratios (ORs) were calculated. Analyses were stratified by type of CHD, gestational age, and network. A total of 609 (0.77%) infants had severe CHD and 76 371 without any malformation served as controls. The mean gestational age and birth weight were 27.8 weeks and 1018 g, respectively. The mortality rate was 18.6% in infants with CHD and 8.9% in controls (propensity score-matched OR, 2.30; 95% CI, 1.61-3.27). Severe CHD was not associated with neonatal brain injury, necrotizing enterocolitis, or retinopathy of prematurity, whereas the OR for bronchopulmonary dysplasia increased. Mortality was higher in all types, with the highest propensity score-matched OR (4.96; 95% CI, 2.11-11.7) for CHD causing congestive heart failure. While mortality did not differ between groups at <27 weeks' gestational age, adjusted OR for mortality in infants with CHD increased to 10.9 (95% CI, 5.76-20.70) at 31 weeks' gestational age. Rates of CHD and mortality differed significantly between networks. Conclusions Severe CHD is associated with significantly increased mortality in very preterm infants.

Retrospective cohort. Tertiary university-affiliated medical centre. All newborns of low-risk singleton pregnancies born at 39+0 to 44+0 weeks&amp;#39; gestation over a 5-year period. multiple gestation, maternal hypertensive disorder, diabetes or cholestasis, placental abruption or intrapartum fever (&amp;gt;38°C), small for gestational age (&amp;lt;10th centile) and major congenital or chromosomal anomalies. None. Admission to the neonatal intensive care unit (NICU), hospital length of stay, 5-min Apgar score, birth trauma, respiratory, neurological, metabolic and infectious morbidities and neonatal mortality. The adverse outcome rate was compared among three groups based on gestational age at birth: post-term (≥42+0 weeks), late term (41+0 to 41+6 weeks) and full term (39+0 to 40+6 weeks). Of the 23 524 eligible neonates, 747 (3.2%) were born post-term, 4632 (19.7%) late term and 18 145 (77.1%) full term. Women in the post-term group versus the late-term group had a significantly higher rate of caesarean section (8.9% vs 5.6%, p&amp;lt;0.001) and operative vaginal delivery (9.6% vs 7.4%, p=0.024). Post-term pregnancy versus full-term pregnancy was associated with an increased risk of NICU admission (OR 2.0, 95% CI 1.4 to 2.8), respiratory morbidity (OR 2.2, 95% CI 1.3 to 3.8) and infectious morbidity (OR 1.88, 95% CI 1.32 to 2.69). Post-term pregnancy versus late-term pregnancy was similarly associated with an increased risk of NICU admission (OR 2.0, 95% CI 1.4 to 2.9), respiratory morbidity (OR 2.7, 95% CI 1.5 to 5.0) and infectious morbidity (OR 1.8, 95% CI 1.2 to 2.7) and with hypoglycaemia (OR 2.6, 95% CI 1.2 to 5.4). Post-term delivery was not associated with neonatal mortality. Post-term pregnancy is an independent risk factor for neonatal morbidity even in low-risk singleton pregnancies.

A retrospective cohort study design was used. The study group included all low-risk singleton term (37 + 0 to 41 + 6 weeks) newborns delivered in a single tertiary university-affiliated medical center over a 5-year period. Outcome of neonates delivered at 37 + 0 to 37 + 6 weeks of gestation (early term) and 41 + 0 to 41 + 6 weeks of gestation (late term) was compared to that of neonates delivered at 39 + 0-39 + 6 weeks of gestation (control). Overall, the outcome of 30 229 neonates was analyzed. The incidence of neonatal mortality was 1.0 per 1000 live-born neonates, with no significant difference between the various gestational age groups. Early term newborns were at higher risk for respiratory morbidity, hypoglycemia, hypocalcemia, thrombocytopenia and unexplained jaundice, and had higher rates of prolonged hospital stay, NICU admission, sep...

Neonates were to be placed in a protective infant carrier (PIC) or an improved PIC ("active PIC") to which filtered air was actively introduced by a blower. The specific needs of low birthweight babies hospitalized in intensive care units and treated in incubators were not adequately addressed. Transfer to a PIC meant disconnecting the infants from life-supporting systems and monitoring devices and exposing them to changes in ambient temperature. To overcome this difficulty the original incubator was used as a CW protective device. Its ports were sealed and low-grade positive pressure was created. This avoided transfer of the neonates from their controlled environment, reduced physiological stress, and improved medical supervision.

In a retrospective study, neonates born to mothers with intrapartum fever, (≥ 37.8°C), were compared to control group matched by gestational age and birthweight. Overall, 159 singleton full term neonates born to women with intrapartum fever (study group) were compared to 159 control infants. No differences in neonatal outcomes were found between the two groups except for a higher rate of meconium-stained amniotic fluid in the maternal-fever group. There were no cases of neonatal infection, severe neonatal morbidity, or neonatal mortality in either of the groups. Full sepsis workup and intravenous antibiotic treatment were provided to 17.6% of the neonates in the study group. Logistic regression analysis revealed that delivery by Cesarean section was the only factor independently associated with the decision to perform a full sepsis work up and antibiotic treatment in cases of maternal intrapartum fever (OR 32.0, 95% CI 9.4-112.1). In low-risk women with asymptomatic intrapartum fever, neonatal infection is uncommon, so that aggressive evaluation and management of these infants may not be necessary and should be balanced against the low risk of neonatal sepsis.

We aimed to identify risk factors for BT and to evaluate the effect of BT on short-term neonatal outcome. A retrospective, cohort, case-control study of all cases of BT in a single tertiary center (1986-2009). The control group included the two subsequent full-term singleton neonates who did not experienced BT. Short-term neonatal outcome was compared between the groups including Apgar scores, NICU admission, duration of hospitalization and neurologic, respiratory and metabolic morbidity. Of the 118 280 singleton full-term newborns delivered during the study period, 2874 were diagnosed with BT (24.3/1000). The most frequent types of BT were scalp injuries (63.9%, 15.5/1000) and clavicular fracture (32.1%, 7.7/1000). The following factors were found to be independent risk factors for BT: instrumental delivery (OR 7.5, 95% CI 6.3-8.9), birth weight, delivery during risk hours, parity, maternal age and neonatal head circumference. Cesarean delivery was the only factor protective of BT (OR 0.2, 95% CI 0.2-0.3). Neonates in the study group had a prolonged length of hospital stay (3.3 versus 2.7 d, p = 0.001), were more likely to be admitted to the NICU (3.9% versus 1.9%, p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001), and had a higher rate of jaundice (11.9% versus 7.1%, p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001) and neurological morbidity (4.7% versus 2.3%, p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001). Instrumental delivery appears to be responsible for most cases of neonatal BT.
