RESUMEN
BACKGROUND: Neonatal intensive care unit (NICU) admission among term neonates is a rare event. The aim of this study was to study the association of the NICU admission of term neonates on the risk of long-term childhood mortality. METHODS: A single-center case-control retrospective study between 2005 and 2019, including all in-hospital ≥ 37 weeks' gestation singleton live-born neonates. The center perinatal database was linked with the birth and death certificate registries of the Israeli Ministry of Internal Affairs. The primary aim of the study was to study the association between NICU admission and childhood mortality throughout a 15-year follow-up period. RESULTS: During the study period, 206,509 births were registered; 192,527 (93.22%) term neonates were included in the study; 5292 (2.75%) were admitted to NICU. Throughout the follow-up period, the mortality risk for term neonates admitted to the NICU remained elevated; hazard ratio (HR), 19.72 [14.66, 26.53], (p < 0.001). For all term neonates, the mortality rate was 0.16% (n = 311); 47.9% (n = 149) of those had records of a NICU admission. The mortality rate by time points (ratio1:10,0000 births) related to the age at death during the follow-up period was as follows: 29, up to 7 days; 20, 7-28 days; 37, 28 days to 6 months; 21, 6 months to 1 year; 19, 1-2 years; 9, 2-3 years; 10, 3-4 years; and 27, 4 years and more. Following the exclusion of congenital malformations and chromosomal abnormalities, NICU admission remained the most significant risk factor associated with mortality of the study population, HRs, 364.4 [145.3; 913.3] for mortality in the first 7 days of life; 19.6 [12.1; 32.0] for mortality from 28 days through 6 months of life and remained markedly elevated after age 4 years; HR, 7.1 [3.0; 17.0]. The mortality risk related to the NICU admission event, adjusted for admission diagnoses remained significant; HR = 8.21 [5.43; 12.4]. CONCLUSIONS: NICU admission for term neonates is a pondering event for the risk of long-term childhood mortality. This group of term neonates may benefit from focused health care.

BACKGROUND: Hemoglobin A1C (HbA1c) is a form of glycated hemoglobin used to estimate glycemic control in diabetic patients. Data regarding the prognostic significance of HbA1c levels in contemporary intensive cardiac care unit (ICCU) patients is limited. METHODS: All patients admitted to the ICCU at a tertiary care medical center between January 1, 2020, and June 30, 2021, with documented admission HbA1c levels were included in the study. Patients were divided into 3 groups according to their HbA1c levels: < 5.7 g% [no diabetes mellitus (DM)], 5.7-6.4 g% (pre-DM), ≥ 6.5 g% (DM). RESULTS: A total of 1412 patients were included. Of them, 974 (69%) were male with a mean age of 67(± 15.7) years old. HbA1c level < 5.7 g% was found in 550 (39%) patients, 5.7-6.4 g% in 458 (32.4%) patients and ≥ 6.5 g% in 404 (28.6%) patients. Among patients who did not know they had DM, 81 (9.3%) patients had high HbA1c levels (≥ 6.5 g%) on admission. The crude mortality rate at follow-up (up to 1.5 years) was almost twice as high among patients with pre-DM and DM than in patients with no DM (10.6% vs. 5.4%, respectively, p = 0.01). Interestingly, although not statistically significant, the trend was that pre-DM patients had the strongest association with mortality rate [HR 1.83, (95% CI 0.936-3.588); p = 0.077]. CONCLUSIONS: Although an HbA1c level of ≥ 5.7 g% (pre-DM & DM) is associated with a worse prognosis in patients admitted to ICCU, pre-DM patients, paradoxically, have the highest risk for short and long-term mortality rates.

RESEARCH QUESTION: Is extended fertility at the advanced reproductive age of 43-47 years associated with high anti-Müllerian hormone (AMH) concentrations? DESIGN: Prospective cohort study including 98 women aged 43-47 years old with a spontaneous conception who were tested for AMH concentrations 1-4 days and 3-11 months post-partum. AMH concentrations at 3-11 months post-partum were further compared with AMH concentrations in healthy age-matched controls that last gave birth at ≤42 years old. Women with current use of combined hormonal contraceptives (CHC), ovarian insult or polycystic ovary syndrome were excluded. Power analysis supported the number of participating women. RESULTS: Median AMH concentrations did not differ between the extended fertility (nâ¯=â¯40) and control (nâ¯=â¯58) groups (0.50 versus 0.45 ng/ml, Pâ¯=â¯0.51). This remained when analysing by age (≥ or <45 years old). AMH concentrations and women's age did not correlate within the extended fertility group (râ¯=â¯0.017, Pâ¯=â¯0.92); a weak negative correlation was found within the control group (râ¯=â¯-0.23, Pâ¯=â¯0.08). AMH was significantly higher 3-11 months post-partum (0.50 ng/ml [0.21-1.23]) than 1-4 days post-partum (0.18 ng/ml [0.06-0.40]), P < 0.001. The two results for each participant were highly correlated (râ¯=â¯0.82, P < 0.001). The extended fertility and control groups were similar regarding age, age at menarche, past CHC use and history of fertility concern. Parity differed but showed no significant correlation with AMH. CONCLUSIONS: Serum AMH concentrations that reflect ovarian reserve do not seem to predict reproductive potential at highly advanced age. Thus, additional factors such as oocyte quality should also be considered in evaluating reproductive potential. AMH suppression that is associated with pregnancy at 1-4 days post-partum recovers at 3-11 months post-partum in women of highly advanced reproductive age.

Objectives: Asthma is a multifactorial, heterogeneous, complex and common chronic respiratory disease driven by diverse mechanisms. Although asthma presents various clinical forms with different levels of severity, it is unclear whether asthma severities are a consequence of disease management or varied etiologies. We sought to investigate this question.Methods: This article presents a cross-sectional study of 113,671 Israeli adolescents. Univariate and multivariable logistic regression models were performed to analyze the independent associations between mild asthma and moderate-to-severe asthma phenotypes and coexistent medical conditions within each gender separately. Hierarchical clustering of the odds ratios of the diverse statistically significant medical conditions associated with asthma severity-gender groups was also performed. We focused on the allergic and neurological-cognitive-mental disorders.Results: Among males, two associations were common to both asthma groups (atopic dermatitis and allergic rhinitis), five unique to mild asthma (urticaria/angioedema, Hymenoptera/bee allergies, allergic conjunctivitis, epilepsy and migraine) and two unique to moderate-to-severe asthma (learning disabilities and ADD/ADHD (Attention-deficit disorder/Attention-deficit/hyperactivity disorder)). Among females, two associations were common to both clinical asthma groups (allergic rhinitis and urticaria/angioedema), and five unique to moderate-to-severe asthma (atopic dermatitis, learning disabilities, ADD/ADHD, anxiety/mood disorders and migraine). Allergic rhinitis was the only condition to be associated with all four groups. Learning disabilities and ADD/ADHD were only associated with moderate-to-severe asthma (but not with mild asthma), in both males and females. Hierarchical clustering analysis uncovered two prominent clusters, separating mild from moderate-to-severe asthma.Conclusions: The differences between mild and moderate-to-severe asthma enhance asthma phenotype characterization, with respect to comorbidities, and indicate varied etiologies.

PURPOSE: We aimed to evaluate the effect of an absorbable adhesion barrier (oxidized regenerated cellulose) for the prevention of peritoneal adhesions in women undergoing repeat cesarean delivery (CD). METHODS: This is a retrospective, single center study that included all women who underwent two consecutive CDs, 2011-2018. Women in whom an absorbable adhesion barrier (oxidized regenerated cellulose) was placed at the time of the initial CD (index CD) were compared to women in whom no such barrier was placed. The association between absorbable adhesion barrier placement at index CD and the presence of intraperitoneal adhesions at subsequent CD was assessed. Factors evaluated included intraperitoneal adhesion severity, time from skin incision to newborn delivery and total duration of surgery. RESULTS: We identified 2125 women that met the inclusion criteria. They were divided into two groups; those in whom an absorbable adhesion barrier was placed at index CD and those in whom no such absorbable barrier was placed. 161 (7.6%) had an absorbable adhesion barrier placed at index CD. At the time of index CD, the rate of intra-peritoneal adhesions was 34.8% in the absorbable adhesion barrier group vs 26.5% in the group without the absorbable adhesion barrier (p = 0.02). At the time of subsequent CD, the rate of intraperitoneal adhesions was 39.8% in the absorbable adhesion barrier group vs 46% in the group without the absorbable adhesion barrier (p = 0.13). Notably, the use of an absorbable adhesion barrier lowered the mean increase in adhesions rate 0.05 ± 0.55 vs 0.20 ± 0.55 (p < 0.01). Absorbable adhesion barrier placement at index CD was found to be independently associated with a lower rate of intraperitoneal adhesions at subsequent CD, aOR 0.67 (0.47-0.96). Overall, absorbable adhesion barrier placement at index CD was associated with a shorter mean duration of subsequent surgery (min), 37.7 ± 18.9 vs. 42.7 ± 27.1 (p = 0.02). CONCLUSION: Absorbable adhesion barrier placement is associated with reduction in intraperitoneal adhesions and duration of surgery in subsequent CD.

OBJECTIVES: Despite encouraging data gathered in inflammatory bowel diseases (IBD) patients, Vedolizumabs' (VDZ) safety profile in pregnancy is not established. DESIGN: Data of 330 consecutive pregnancies with IBD was prospectively collected. RESULTS: Women with IBD were treated with: VDZ (n = 24), anti-tumor necrosis factors (n = 82) or conventional therapy (n = 224). Gravidity and parity were similar among the 3 groups. The VDZ group was comprised mostly of Crohn's disease patients who were all not naïve to biological treatment. They had significantly higher conception rates during active disease (P < 0.05), with fewer flares during pregnancy. DISCUSSION: Although further study is needed, VDZ appears of low risk during pregnancy.

Objective To assess the maternal group B streptococcal (GBS) colonization rate and neonatal early-onset GBS (EOGBS) disease in term deliveries, a decade apart. Methods This was a retrospective computerized study between 2005 and 2016. A universal GBS culture-based approach gradually replaced the GBS risk-oriented screening. A vaginal-rectal culture taken at 35-37 weeks was recorded at admission for delivery. Results We identified 149,910 term deliveries during the study period. GBS status was recorded in 53,879 (35.9%) cases. The GBS screening rate constantly increased from 20% in 2005 to 47.5% in 2016. GBS colonization rates significantly decreased, from 50.3% in 2005 to 31.7% in 2016, P<0.001. Overall, EOGBS disease was diagnosed in 37 term neonates (0.25 per 1000 live births.). The rate of EOGBS in neonates decreased dramatically from 0.361 per 1000 deliveries between 2005 and 2009 to 0.19 per 1000 deliveries between 2010 and 2016 (P<0.05). During the latter period, over 35% of the deliveries were screened for GBS. Remarkably, 64.9% of the EOGBS originated in the non-screened population. Conclusion The universal screening policy was associated with a significant decrease in neonatal EOGBS and therefore should be adopted. Further national surveillance studies should be performed in order to validate this approach.

Background Cesarean delivery (CD) in primiparas with a term singleton vertex fetus (PTSV) is a sentinel event for the future mode of delivery and determinant of repeat CD risk. We aimed to evaluate the risk factors for primary CD in a population with a decade of sustained low rate of intrapartum CD. Methods This was a retrospective single-center cohort study between 2005 and 2014. The primary outcome of the study was the mode of delivery. PTSV who attempted vaginal delivery were identified and categorized according to the mode of delivery: vaginal delivery vs. CD. Risk factors for intrapartum CD adjusted odds ratio (aOR) [95% confidence interval (CI)] in multivariate analysis were reported. Results During the study, 121,483 deliveries were registered; 26,301 (21.6%) PTSV were admitted in labor, of which 1944 (7.4%) had an intrapartum CD. Significantly in multivariate analysis, this group had a unique risk profile as compared to those who delivered vaginally; non modifiable risks included advanced maternal age: 3.06 (2.16-4.33), P < 0.001; prior multiple (≥3) miscarriages: 1.94 (1.04-3.62), P = 0.04; low (<6) modified admission cervical score: 2.41 (2.07-2.82), P < 0.001; low birth weight (BW): 1.42 (1.00-2.01), P = 0.05 or macrosomia: 2.38 (1.77-3.21), P < 0.001; modifiable risks included induction of labor: 1.79 (1.51-2.13), P < 0.001 and oxytocin labor augmentation: 8.36 (6.84-10.22), P < 0.001. Conclusion In a population of PTSV with a sustained low risk for intrapartum cesarean maintained by a strict labor management, induction of labor remains a significant and sole potentially modifiable risk factor for CD.

PURPOSE: Intrauterine growth restriction (IUGR) is a leading cause of perinatal morbidity and mortality, carrying a 20% recurrence rate. The placental disease is a cardinal factor among IUGR underlying processes. This study describes placental histopathological features (HPf) characteristic of recurrent IUGR (rIUGR) and assesses association with antenatal Doppler studies. METHODS: We conducted a retrospective case-control study, between the years 2005-2016, evaluating 34 placentae of 17 women with rIUGR, and 59 placentae of a gestational age-matched control. Doppler studies within a week prior to delivery were analyzed for the rIUGR group. RESULTS: Placental HPf characteristic of rIUGR is maternal and fetal vascular malperfusion lesions; maternal accelerated villous maturation and villous infarcts, repetitive feature rate 88.8% (95% CI 37.2-97), and fetal chorionic plate/stem villous thrombi, repetitive feature rate 66.6% (95% CI 30-90.3). Among women with abnormal Doppler, 83.3% had a placenta HPf of maternal vascular malperfusion lesions and 66.7% presented with a hypertensive disorder. CONCLUSIONS: Women with rIUGR are a unique group of patients characterized by repetitive placental HPf of both maternal and fetal vascular malperfusion lesions. Specifically, maternal vascular malperfusion lesions are associated with abnormal Doppler findings. In conclusion, characteristic placental HPf may serve as predictors of future IUGR recurrence, thus offering early recognition of pregnancies that require "high-risk" antenatal care.

OBJECTIVES: While asthma presents various clinical forms with different levels of severity, it is unclear whether asthma severities are a consequence of disease management or varied etiologies. We sought to investigate this question. METHODS: This paper presents a cross-sectional study of 113,671 Israeli adolescents. Prevalence rates of mild and moderate-to-severe asthma over a 24-year period were calculated and multivariate regression models (outcomes: different asthma severity, reference: subjects without asthma) were performed to analyze associations with anthropometric indices and socio-demographic variables, in males and females separately. RESULTS: The prevalence of mild asthma increased until birth years 1976-1980 and then steadily decreased. In contrast, the prevalence of moderate-to-severe asthma was relatively stable until birth years 1976-1980, then rose steeply until 1986-1990 and subsequently plateaued in the early 1990s. Obesity was positively associated with both mild and moderate-to-severe asthma in males (Odds Ratio (OR) [95%CIs]: 1.61 [1.37-1.89] and 1.63 [1.34-1.98], respectively) and females (1.54 [1.10-2.16] and 1.54 [1.20-1.98], respectively). Family size greater than three siblings was negatively associated with both mild and moderate-to-severe asthma in males (0.62 [0.56-0.68] and 0.59 [0.52-0.68]) and females (0.71 [0.60-0.83] and 0.73 [0.63-0.83]). In contrast, in males, underweight was only associated with mild asthma (1.54 [1.22-1.94]) but not with moderate-to-severe asthma. In females, overweight was only associated with moderate-to-severe asthma (1.21 [1.00-1.46]) and rural residence was only associated with mild asthma (1.26 [1.09-1.47]). CONCLUSIONS: The differences between mild and moderate-to-severe asthma enhance asthma phenotype characterization, with respect to secular trends and associated variables, and indicate varied etiologies.

INTRODUCTION: Epidural analgesia has been considered a risk factor for labor dystocia at trial of labor after cesarean (TOLAC) and uterine rupture. We evaluated the association between exposure to epidural during TOLAC and mode of delivery and maternal-neonatal outcomes. MATERIALS AND METHODS: A single center retrospective study of women that consented to TOLAC within a strict protocol between 2006 and 2013. Epidural "users" were compared to "non-users". Primary outcome was the mode of delivery: repeat in-labor cesarean or vaginal birth after cesarean (VBAC). Secondary outcomes were maternal/neonatal morbidities. Univariate/multivariate analyses for associations between epidural and mode of delivery were adjusted for significant covariates/mediators. RESULTS: Of a total of 105,471 births registered, 9464 (9.0%) were eligible for TOLAC; 7149 (75.5%) women consented to TOLAC, among which 4081 (57.1%) had epidural analgesia. The in labor cesarean rate was significantly lower for the epidural "users" 8.7% vs. "non-users" 11.8%, P<0.0001, with a parallel increased rate of instrumental delivery. Uterine rupture rates were comparable: 0.4% and 0.29%, respectively (P=0.31). The adjusted multivariate model showed that epidural "users" were more likely to experience a VBAC, odds ratio (OR) 4.58 [3.67; 5.70]; P<0.0001 with a similar rate of adverse maternal-neonatal outcomes. CONCLUSION: Epidural analgesia at TOLAC may emerge as a safe and significant adjunct for VBAC.

BACKGROUND: Children and adolescents are commonly referred to an orthopedic surgeon to assess knee malalignment. OBJECTIVES: To assess the prevalence of genu varum and valgum among adolescents, and to identify correlates of these conditions. METHODS: A medical database of 47,588 candidates for military service presenting to the northern recruitment center during an 11 year period was analyzed to identify clinical knee alignment. Based on the standing skin surface intercondylar distance (ICD) or intermalleolar distance (IMD), the prevalence rates of genu varum (ICD ≥ 3 cm) and genu valgum (IMD ≥ 4 cm) were calculated. The association of gender, body mass index (BMI), and place of residence to knee alignment was studied. RESULTS: The rates of genu varum and valgum were 11.4% (5427) and 5.6% (2639), respectively. Genu varum was significantly more prevalent among males than females (16.2% vs. 4.4%, P < 0.001). It was also more prevalent among underweight subjects and less prevalent among overweight and obese subjects (P < 0.001). Genu valgum was significantly more prevalent among females than males (9.4% vs. 2.9%) and in overweight and obese subjects compared to those with normal BMI, while less prevalent in underweight subjects (P < 0.001). Multivariate analysis revealed that genu varum was independently positively associated with male gender, underweight, and living in a rural area. Genu valgum was independently positively associated with female gender, overweight, and obesity. CONCLUSIONS: This study establishes a modern benchmark for the cutoff and prevalence of genu varum and valgum as well as associations with gender and BMI.

Use of hormone contraceptives (HC) is very popular in the reproductive age and, therefore, evaluation of ovarian reserve would be a useful tool to accurately evaluate the reproductive potential in HC users. We conducted a retrospective cohort study of 41 HC users compared to 57 non-HC users undergoing IVF-preimplantation genetic diagnosis (PGD) aiming to evaluate the effect of HC on the levels of anti-Mullerian hormone (AMH), small (2-5 mm), large (6-10 mm) and total antral follicle count (AFC) and the ability of these markers to predict IVF outcome. Significant differences in large AFC (p = 0.04) and ovarian volume (p < 0.0001) were seen, however, there were no significant differences in small and total AFC or in serum AMH and FSH levels. Oocyte number significantly correlated with AMH and total AFC in HC users (p < 0.001) while in non-HC users these correlations were weaker. In HC users, the significant predictors of achieving <6 and >18 oocytes were AFC (ROC-AUC; 0.958, p = 0.001 and 0.883, p = 0.001) and AMH (ROC-AUC-0.858, p = 0.01 and 0.878, p = 0.001), respectively. The predictive values were less significant in non-HC users. These findings are important in women treated for PGD, in ovum donors and for assessing the fertility prognosis in women using HC and wishing to postpone pregnancy.

BACKGROUND: The annual procedure volume is an accepted marker for quality of care and has been documented in various medical fields. Surgeon volume has been shown to correlate with morbidity and mortality rates in surgical and high-risk medical procedures. Although cesarean delivery is 1 of the most common surgical procedures in the United States, the link between a surgeon's annual cesarean delivery volume and maternal outcome has never been tested. OBJECTIVE: The purpose of this study was to evaluate the impact of a surgeon's annual volume on short-term maternal outcome in cesarean deliveries. STUDY DESIGN: We performed a retrospective cohort study in a single tertiary center between 2006 and 2013. Cesarean deliveries were categorized into 2 groups based on the annual volume of cesarean delivery of the attending obstetrician. The "low" group included obstetricians with a low annual volume, whose annual volume of cesarean delivery was lower than median. The "high" group comprised obstetricians with a high annual volume whose annual volume was at median and above. Further analyses were done for quartiles and for 4 clinical relevant groups according to the annual number of cesarean deliveries that were performed/supervised by the attending obstetrician (≤20, 21-60, 61-120, and >120). The primary outcome was a composite adverse maternal outcome that included ≥1 of the following outcomes: urinary or gastrointestinal tract injuries, hemoglobin drop >3 g/dL, blood transfusion, relaparotomy, puerperal fever, prolonged maternal hospitalization, and readmission. Secondary outcomes were operative times (skin incision to delivery and overall). RESULTS: A total of 11,954 cesarean deliveries were included; the median annual number of cesarean deliveries that were performed/supervised by 1 obstetrician was 48. Unadjusted analysis suggested that the patients in the high group had fewer urinary and gastrointestinal injuries (18/9278 [0.2%] vs 16/2676 [0.6%] injuries; P < .001), less blood loss as measured by hemoglobin drop >3 g/dL (1053/9278 [11.5%] vs 366/2676 [13.8%]; P < .001), and fewer cases of prolonged maternal hospitalization (80/9278 [0.9%] vs 39/2676 [1.5%]; P = .006). The rate of blood transfusion, relaparotomy, puerperal febrile morbidity, and readmission to hospital did not differ between groups. Multivariable regression analysis showed that cesarean delivery performed/supervised by the high group resulted in a significantly lower composite adverse maternal outcome (15.8% vs 18.9%; odds ratio, 0.86; 95% confidence interval, 0.78-0.95; P = .004). This was related primarily to a decreased frequency of urinary and gastrointestinal injuries, lower likelihood of hemoglobin drop >3 g/dL, and lower incidence of prolonged maternal hospitalization. Operative times were significantly shorter for the high group. Composite adverse maternal outcome ranged from 21.8% in the lowest quartile to 17.9% in quartile 2, to 17.4% in quartile 3, and 15.6% in quartile 4. quartile 4 served as the reference; quartile 3 had an odds ratio of 1.14 (95% confidence interval, 1.01-1.29; P = .029); quartile 2 had an odds ratio of 1.18 (95% confidence interval, 1.02-1.36; P = .021, and quartile 1 had an odds ratio of 1.51 (95% confidence interval, 1.14-1.99; P = .004) for composite adverse maternal outcome. Composite adverse maternal outcome ranged from 21.5% in clinical group 1 to 17.5% in clinical group 2, to 17.9% in clinical group 3, and 15.2% in clinical group 4 (P = .001). Cesarean delivery performed/supervised by clinical groups 2, 3, and 4 in comparison with clinical group 1 were associated with a statistically significant risk reduction, (23%, 25%, and 34% respectively). CONCLUSION: Maternal composite morbidity is decreased as the volume of cesarean deliveries that are performed or supervised by obstetricians increases.

UNLABELLED: Whether intra- and early post-partum hemorrhage is influenced by ABO blood groups remains unknown. Therefore, we compared women with O to non-O blood groups with regard to maternal post-partum hemorrhage and transfusion need. This retrospective study was conducted in a single tertiary center between 2005 and 2014. For the purpose of the study, parturients were categorized as O and non-O blood groups. Data included all deliveries but excluded patients with missing blood grouping or hemoglobin values, and/or stillbirth. Drop in hemoglobin was defined as hemoglobin concentration at admission for delivery minus lowest hemoglobin concentration post-delivery. Study outcomes were postpartum hemorrhage, hemoglobin drop >2-7 g/dL inclusive, and packed red blood cells transfusion. STATISTICS: descriptive, χ(2) (p < 0.05 significant) and multivariable regression models [odds ratio (OR), 95 % confidence interval (CI), p value]. 125,768 deliveries were included. After multivariable analysis, women with O blood type relative to women with non-O blood type had significantly higher odds of postpartum hemorrhage (OR 1.14; 95 % CI 1.05-1.23, p < 0.001), higher odds of statistically significant hemoglobin decreases of >2, 3, or 4 g/dL (OR 1.07; 95 % CI 1.04-1.11, p < 0.001, OR 1.08; 95 % CI 1.03-1.14, p = 0.002, OR 1.14; 95 % CI 1.05-1.23, p = 0.001; respectively), and higher odds, albeit not statistically significant of 5, 6, or 7 g/dL decreases in hemoglobin (OR 1.13; 95 % CI 1.00-1.29, p = 0.055, OR 1.05; 95 % CI 0.84-1.32, p = 0.66, OR 1.15; 95 % CI 0.79-1.68, p = 0.46; respectively), but no difference in blood products transfusion (OR 1.03; 95 % CI 0.92-1.16, p = 0.58). In conclusion, women with blood type O may be at greater risk of obstetrical hemorrhage.

PURPOSE: We speculate that parturients who deliver elsewhere between the first and second deliveries compose a unique clinical group, characterized by higher rates of cesarean section (CS) both in the first and second deliveries, compared with parturients who deliver both deliveries at the same hospital. METHODS: A retrospective study conducted at Shaare Zedek Medical Center in a tertiary university-affiliated hospital. The cohort included all women in the second delivery, aged ≤24 years with a singleton pregnancy who delivered their second child in our medical center during 2010-2012. Parturients who delivered both the first and second children in our medical center ("stayers") were compared with parturients who delivered their first child in a different hospital ("switchers"). Groups were compared in regard to history of CS in the first delivery and obstetric complications in the second delivery, including CS, instrumental vaginal delivery (IVD), preterm delivery (PTD), and postpartum hemorrhage (PPH). Logistic regressions were constructed to study if delivering elsewhere between the first and second deliveries was a risk for adverse pregnancy outcome, followed by multivariate analysis controlling for confounders. RESULTS: In all, 4166 parturients were included: "stayers" = 3163 and "switchers" = 1003. History of CS in the first delivery was approximately twice as prevalent in "switchers" (12 versus 6.3 %, p < 0.000). "Switchers" experienced higher rates of CS: OR = 1.8 (95 % CI 1.2-2.3); IVD: OR = 1.3 (95 % CI 0.8-2.1); and PTD (<37w): OR = 1.4 (95 % CI 1.0-1.9). CONCLUSIONS: Parturients who deliver elsewhere between the first and second childbirth are at increased risk for CS and PTD in the second delivery; hence, the decision to deliver elsewhere after the first delivery should be considered as a risk marker for obstetric complication.

BACKGROUND: Fertility treatments are responsible for the rise in high order pregnancies in recent decades and their associated complications. Reducing the number of embryos returned to the uterus will reduce the rate of high order pregnancies. OBJECTIVES: To explore whether obstetric history and parity have a role in the clinician's decision making regarding the number of embryos transferred to the uterus during in vitro fertilization (IVF). METHODS: In a retrospective study for the period August 2005 to March 2012, data of twin deliveries > 24 weeks were collected, including parity, mode of conception (IVF vs. spontaneous), gestational age at delivery, preeclampsia, birth weight, admission to the neonatal intensive care unit (NICU), and Apgar scores. RESULTS: A total of 1651 twin deliveries > 24 weeks were record- ed, of which 959 (58%) were at term (> 37 weeks). The early preterm delivery (PTD) rate (< 32 weeks) was significantly lower with increased parity (12.6%, 8.5%, and 5.6%, in women with 0, 1, and ≥ 2 previous term deliveries, respectively). Risks for PTD (< 37 weeks), preeclampsia and NICU admission were significantly higher in primiparous women compared to those who had one or more previous term deliveries. Primiparity and preeclampsia, but not IVF, were significant risk factors for PTD. CONCLUSIONS: The risk for PTD in twin pregnancies is significantly lower in women who had a previous term delivery and decreases further after two or more previous term deliveries. This finding should be considered when deciding on the number of embryos to be transferred in IV.

BACKGROUND: Maternal iron deficiency anemia (IDA) impacts placenta and fetus. We evaluated effects of IDA at admission for delivery on cesarean rates, and adverse maternal and neonatal outcomes. STUDY DESIGN AND METHODS: Medical records from Jerusalem (2005-2012) identified women with a live-birth singleton fetus in cephalic presentation of any gestational age and excluded planned cesarean, chronic/gestational diseases identified with anemia. Study population was divided into anemic and non-anemic women using WHO criteria. MAIN OUTCOME MEASURES: cesarean rate, and adverse outcomes (maternal: packed cells transfusion, early post-partum hemorrhage, preterm delivery; and neonatal: 5' Apgar < 7, Neonatal Intensive Care Unit [NICU] admission, extreme birthweights). Continuous variable analysis and multivariate backward step-wise logistic regression models were prepared with Odds Ratios (OR) and 95% confidence intervals (CI). RESULTS: In all, 96,066 deliveries were registered, of which 75,660 (78.8%) were included. IDA was present in 7,977 women (10.5%). Anemia at birth was significantly associated with cesarean section (OR 1.30; 95%CI, 1.13-1.49, p < 0.001), packed cells transfusion (OR 5.48; 95%CI, 4.57-6.58, p < 0.001), preterm delivery (OR 1.54; 95%CI, 1.36-1.76, p < 0.001), macrosomia (OR 1.23; 95%CI, 1.12-1.35, p < 0.001), Large for Gestational Age (OR 1.29; 95%CI, 1.20-1.39, p < 0.001), Apgar 5' < 7 (OR 2.21; 95%CI, 1.84-2.64, p < 0.001), and NICU admission (OR 1.28; 95%CI, 1.04-1.57, p = 0.018). CONCLUSION: Iron deficiency anemia at delivery is associated with an increased risk for cesarean section and adverse maternal and neonatal outcomes in otherwise healthy women. Monitoring/correction of hemoglobin concentrations even in late pregnancy may prevent these adverse events.

PURPOSE: To revisit risk factors of major obstetric hemorrhage in a large obstetric center. STUDY DESIGN: A retrospective case control study was conducted based on institutional electronic database and blood bank registry of a single center, 2005-2014. The major obstetric hemorrhage event was defined as transfusion of ≥5 red blood cells units within 48 h of birth and compared to matched group (ratio 1:4) based on the time of birth. Multivariable stepwise backward logistic regression models were fitted to determine risk factors for major obstetric hemorrhage. Odds ratio (OR), further evaluated by standard measures of the predictive accuracy of the logistic regression models, C statistics, and associated neonatal adverse outcome are reported. RESULTS: 113,342 women delivered during the study; 122 (0.1 %) women experienced major obstetric hemorrhage. There was one major obstetric hemorrhage fatality (0.8 %). Compared to the controls, we identified historical as well as significant current modifiable risk factors for major obstetric hemorrhage: multifetal pregnancy (OR 3.92; 95 % CI 1.34-11.52; p = 0.013), induction of labor (OR 2.81; 95 % CI 1.22-7.05; p = 0.027), cesarean section (OR 25.56; 95 % CI 12.88-50.75; p < 0.001), and instrumental delivery (OR 6.58; 95 % CI 2.36-18.3; p < 0.001). C statistics of the model for major obstetric hemorrhage prediction was 0.919 (95 % CI 0.890-0.948, p < 0.001). CONCLUSION: Major obstetric hemorrhage is a rare event with potentially modifiable risk factors which represent a platform of interventions for lessening obstetric morbidity.

AIM: To evaluate the effect of elective induction at term for women with gestational diabetes mellitus (GDM) on the risk for cesarean delivery. STUDY DESIGN: This is a retrospective case-control matched study, based on a single-center computerized database, 2005-2011. The medical records were reviewed for GDM management and glycemic control. For the study, two groups were defined: Group 1, women diagnosed with GDM with an estimated fetal weight <4,000 g, electively induced at term; Group 2, women induced due to Term-PROM, an indication for term induction in normoglycemic women with uncomplicated pregnancies, matched for age and parity (ratio 1:2). The primary outcome was cesarean delivery and secondary outcomes included other maternal and neonatal events. Descriptive analyses and multivariate analyses models were fitted. RESULTS: GDM was diagnosed in 1,873 (2.6 %) women of 72,374 births; 227 (12.1 %) were eligible for inclusion in Group 1 and matched with 454 women in Group 2. GDM management included diet in 103 (45.4 %), insulin in 81 (35.7 %), and oral hypoglycemic agents in 43 (18.9 %).The cesarean delivery rate was significantly higher in Group 1, 17.1 vs. 11.2 % (p = 0.02). Three out of four births complicated by shoulder dystocia and BW <4,000 g, occurred in Group 1 (p = 0.076) and were associated with no glycemic control. Other obstetrical-related outcomes such as instrumental birth, severe perineal tears, early postpartum hemorrhage and peripartum transfusion were similar between groups. CONCLUSION: Elective induction at term for women with GDM is associated with an increased risk for cesarean delivery as compared to other elective induction of labor.
