Enhanced expression of Galectin-3 in gestational diabetes.

BACKGROUND AND AIMS: Gestational diabetes mellitus (GDM), hyperglycemia diagnosed during pregnancy, is one of the most common medical complications of pregnancy, treated primarily by diet and pharmacotherapy, if indicated. It is well-established that GDM increases the risk of adverse pregnancy outcomes and long-term complications in mothers and infants. Galectin-3 (Gal-3) is important in processes of cell growth, differentiation, inflammation, and fibrosis. We evaluated Gal-3 expression in pregnancies complicated by GDM as a parameter that might explain how GDM influences early onset of future complications. METHODS AND RESULTS: Forty-four women with GDM and 40 with normal pregnancy (NP) were recruited during delivery admission. Blood samples were obtained from parturients and umbilical cords blood, as well as placental tissue for analysis. Gal-3 mRNA expression was increased in maternal blood samples and placental tissue of women with GDM compared to NP. In GDM, Gal-3 mRNA was decreased in cord blood compared to maternal blood and placental tissue. Gal-3 GDM placental protein expression was increased compared to NP. Immunostaining revealed that Gal-3 is upregulated in GDM placental extravillous trophoblast. ELISA of Gal-3 maternal serum levels between GDM and NP were similar. CONCLUSION: Gal-3 is strongly expressed at molecular levels (mRNA and protein expression) in GDM maternal blood and placental tissue, and decreased in cord blood. These findings highlight the role of the placenta in protecting the fetus from potential Gal-3 damage. Gal-3 expression at mRNA and protein levels might be influenced by diabetes, even if blood glucose is balanced by medication or diet.

Diagnostic accuracy of random urinary protein-to-creatinine ratio for proteinuria in patients with suspected pre-eclampsia.

PURPOSE: To evaluate the correlation between urine protein/creatinine ratio (UPCR) and proteinuria in a 24-h urine collection and to calculate the predicative accuracy of different cutoffs of UPCR for the diagnosis of proteinuria. METHODS: A retrospective cohort study including women who admitted for the evaluation for suspected preeclampsia (PET) beyond 20 weeks of gestation in a single tertiary center. Both UPCR test and quantification of proteinuria using 24-h urine collection were obtained during their index hospitalization no more than 48 h apart. Women with pre-existing diabetes mellitus, known renal disease or proteinuria prior to pregnancy or chronic hypertension were excluded. Predictive accuracy of UPCR for several cutoffs of proteinuria was evaluated. Multivariate logistic regression analysis was used to assess diagnostic accuracy of UPCR in sub-populations according to obstetrical characteristics. RESULTS: Overall 463 patients were included. Of them 316 (68.3%) have 24-h urine protein collection of ≥ 300 mg/day. Mean gestational age at evaluation was 34.0 ± 3.4 weeks. Median (and interquartile range) time interval between UPCR and 24-h urine collection was 1.8 (1.6-1.9) days. Sensitivity and specificity of UPCR of 0.3 for predicting proteinuria ≥ 300 mg/day were 90.1% and 63.3%, respectively. The corresponding values for difference proteinuria cutoffs: ≥ 1000 mg/day and 5000 mg/day were 98.4, 100% and 29.1, 36.0%, respectively. The optimal UPCR thresholds for 24-h urine protein collection of ≥ 300 mg/day, ≥ 1000 mg/day and 5000 mg/day were 0.31, 0.70 and 2.49, respectively. The predictive accuracy of UPCR > 0.30 in predicting proteinuria was unaffected by demographic and obstetrical characteristics as maternal age, pre-pregnancy BMI, gestational age at examination, creatinine levels or by multiple gestation [adjusted OR 18.27 (95% CI 9.97-33.47)]. CONCLUSION: UPCR was strongly correlated with various cutoffs of proteinuria obtained by 24-h urine collection. UPCR cutoff varied depending on the specific measured outcome. This correlation was not affected by gestational age at examination.

Thioredoxin, thioredoxin interacting protein and transducer and activator of transcription 3 in gestational diabetes.

To evaluate changes in the inflammatory response of thioredoxin (TXN), thioredoxin interacting protein (TXNIP), transducer and activator of transcription 3, NFƙB-p50 and STAT3 at the level of maternal serum, placenta, and umbilical cord blood of women with gestational diabetes mellitus type 2 (GDMA2) compared to normal pregnancies (NP). Thirty pregnant women (20 with GDMA2 and 10 NP) were recruited during admission for delivery. Blood samples were obtained from the parturients and umbilical cords, as well as placental tissue for mRNA and protein extraction. TXNIP mRNA expression was significantly increased in maternal serum of women with GDMA2 compared to NP women. TXNIP mRNA was significantly decreased in GDMA2 placentas and cord blood compared to NP. TXN/TXNIP mRNA ratio showed significantly high absolute values in placental and cord blood (2.39 and 1.66) respectively, compared to maternal ratio (1.084) (P < 0.001). TXN/TXNIP placenta protein ratio showed similar values between GDMA2 and NP (0.98 and 0.86; P = 0.7). STAT3 and its target protein SOCS3, as well as NFƙB-p50 mRNA expression were significantly increased in placentas of GDMA2. NFƙB-p50 mRNA expression was significantly decreased in cord blood compared to both maternal and placental mRNA expression. Pro-inflammatory changes are expressed by low mRNA TXN/TXNIP ratio in maternal blood of GDMA2 patients, but not in placental and umbilical cord blood samples. This, as well as the feedback role of SOCS3 in STAT3 pathway and NFƙB-p50 expression, may indicate that the placenta has a role in protecting the fetus from damage due to inflammatory response, which is common in diabetes.

The yield of chromosomal microarray testing for cases of abnormal fetal head circumference.

Objectives: Chromosomal microarray analysis (CMA) is the method of choice for genetic work-up in cases of fetal malformations. We assessed the detection rate of CMA in cases of abnormal fetal head circumference (HC). Methods: The study cohort was based on 81 cases of amniocenteses performed throughout Israel for the indication of microcephaly (53) or macrocephaly (28), from January 2015 through December 2018. We retrieved data regarding the clinical background, parental HCs and work-up during the pregnancy from genetic counseling summaries and from patients' medical records. Results: There was only one likely pathogenic CMA result (1.89%): a 400-kb microdeletion at 16p13.3 detected in a case of isolated microcephaly. No pathogenic results were found in the macrocephaly group. Most fetuses with microcephaly were female (87.8%), while the majority with macrocephaly were males (86.4%). Conclusions: The results imply that CMA analysis in pregnancies with microcephaly may carry a small yield compared to other indications. Regarding macrocephaly, our cohort was too small to draw conclusions. In light of the significant gender effect on the diagnosis of abnormal HC, standardization of fetal HC charts according to fetal gender may normalize cases that were categorized outside the normal range and may increase the yield of CMA for cases of abnormal HC.

Gestational Diabetes Type 2: Variation in High-Density Lipoproteins Composition and Function.

Aims: Class A2 gestational diabetes mellitus (GDMA2) has short- and long-term effects on the mother and child. These may include abnormalities of placentation, damage to endothelial cells and cardiovascular disease. This research investigated the function and composition of high-density lipoproteins (HDL) among women with GDMA2 and their fetuses. Methods: Thirty pregnant women were recruited during admission for delivery. The function and expression of HDL, paraoxonase1 (PON1) and apolipoprotein A1 (APOA1) in the blood samples and the placental tissue were evaluated. The effect of HDL on migration of endothelial cells was measured in vitro. Results: Compared to normal pregnancy (NP), APOA1 in the maternal plasma of women with GDMA2 was decreased. More APOA1 and PON1 were released from HDL of women with GDMA2, compared to NP. Placental APOA1 and PON1 were decreased in GDMA2. For endothelial cells stimulated with TNFα, HDL cell migration was decreased when cells were evaluated with NP-HDL, as compared to GDMA2-HDL. Conclusions: GDMA2 affects the composition and function of HDL in plasma. Changes in HDL commonly seen in GDMA2 were observed in maternal and placental samples, but not in cord samples. These results might indicate a placental role in protecting the fetus by preserving the components and functions of HDL and require further investigation.

Does stress affect IVF outcomes? A prospective study of physiological and psychological stress in women undergoing IVF.

RESEARCH QUESTION: What are the effects of physiological and psychological stress on fertility outcomes for women undergoing IVF? DESIGN: A prospective cohort study of 72 patients undergoing IVF in 2017 and 2018. Physiological stress was assessed by salivary cortisol measurements: (i) pretreatment, when the patient received the IVF protocol; (ii) before oocyte retrieval (follicular cortisol was also measured); and (iii) before embryo transfer. Emotional stress was evaluated at each assessment with the State-Trait Anxiety Inventory and a 1-10 Visual Analogue Scale (VAS, referred to as the 'Stress Scale'. Correlations between cortisol concentrations, psychological stress and IVF outcome were assessed. RESULTS: Salivary cortisol concentrations increased by 28% from pretreatment phase (0.46 ± 0.28 µg/dl) to maximum concentration on oocyte retrieval day (0.59 ± 0.29 µg/dl, P = 0.029) and then decreased by 29% on embryo transfer day (0.42 ± 0.23 µg/dl, P = 0.0162). On embryo transfer day, cortisol among women in their first cycle was higher than women who underwent more than one treatment (P = 0.024). Stress Scale score increased by 39% from pretreatment to a maximum score on oocyte retrieval day and then decreased by 12% on embryo transfer day. Salivary cortisol and Stress Scale were not related to subsequent embryo transfer, fertilization rate, embryo quality or clinical pregnancy rate. Follicular cortisol concentration was positively correlated with fertilization rate (r = 0.4, P = 0.004). CONCLUSION: It can be cautiously concluded that physiological and psychological stress do not negatively affect IVF outcomes. Moreover, high follicular cortisol concentrations might have positive effects on pregnancy rates.

Physiological and psychological stress responses to labor and delivery as expressed by salivary cortisol: a prospective study.

BACKGROUND: Labor is considered a stressful event, yet no study has described the course of stress measured by cortisol during labor and postpartum. OBJECTIVE: The objective of the study was to describe the patterns of physiological and psychological stress during labor as measured by salivary cortisol concentrations and stress questionnaires and their correlation to obstetric and neonatal outcomes. STUDY DESIGN: This prospective, observational study included 167 women with low-risk, singleton, term deliveries at a tertiary academic center. Physiological stress was evaluated by salivary cortisol measurements and emotional stress by questionnaire (stress scale ranging from 0 to 10) during the latent phase, active phase, and full dilation stages of labor as well as 2 minutes, 2 hours, and 24 hours after delivery. Cord blood cortisol and pH were also obtained. Modes of delivery, complications during labor and delivery, and early neonatal outcomes were evaluated. RESULTS: Salivary cortisol concentrations increased gradually from latent phase to active phase. The maximum increase was observed within 2 minutes of the delivery (from an average of 1.06 µg/dL to 1.67 µg/dL; 57% increase). Within 2 hours after delivery, cortisol decreased and reached a nongravid concentration after 24 hours (0.16 µg/dL). Cortisol concentrations during labor and up to 2 hours postpartum were above the average concentration of nongravid women (0.5 µg/dL). Women with epidural anesthesia had lower cortisol concentrations at complete dilation (P = .026) and 2 hours postpartum (P = .016) compared with women without epidural. Psychological stress peaked during latent and full dilation phases (mean 4.56 and 4.29, respectively). Maximum decrease from 4.29 to 2.04 (52%) occurred immediately postpartum. Cord cortisol was higher among women delivered by vacuum extraction compared with spontaneous vaginal delivery (17 ± 2 vs 11 ± 3.8, P = .03). CONCLUSION: This study reveals the course of cortisol concentrations during labor for low-risk pregnancies, with maximum increase immediately postpartum. Subjective stress levels decreased over the course of labor. Salivary cortisol portrays stress during labor and may be used as a reference to evaluate complicated pregnancies and to evaluate the role of cortisol during these deliveries.

Labor progression of women attempting vaginal birth after previous cesarean delivery with or without epidural analgesia.

PURPOSE: Normal labor curves have not been assessed for women undergoing a trial of labor after cesarean delivery (TOLAC). This study examined labor patterns during TOLAC in relation to epidural analgesia use. METHODS: Retrospective cohort study of deliveries of women undergoing TOLAC at a single, academic, tertiary medical center. Length of first, second and third stages of labor was compared between 424 women undergoing TOLAC in the current labor with no previous vaginal delivery (VD) and 357 women with at least one previous VD and current TOLAC. RESULTS: Women in the TOLAC only group had significantly longer labors compared to women in the previous VD and TOLAC group. In both groups, women who underwent epidural analgesia had longer first and second stages of labor. In the TOLAC only group, more women who had epidural analgesia tended to deliver vaginally as compared to those who did not (P = 0.09). For women who delivered vaginally, the 95th percentile for the second stage duration with epidural was 3.40 h in the TOLAC only group and 2.3 h in the previous VD and TOLAC group. The 95th percentile for the second stage duration without epidural was 1.4 h in the TOLAC only group and 0.9 h in the previous VD and TOLAC group. CONCLUSIONS: Operative intervention (instrumental delivery/cesarean delivery (CD)) might be considered for women attempting TOLAC after a 2-h duration of second stage without epidural and 3-h duration with epidural, with an hour less for women who also had previous VD.

Does music during labor affect mode of delivery in first labor after epidural anesthesia? A prospective study.

KEY MESSAGE: Listening to music during labor increases the likelihood that primiparas will have a spontaneous vaginal delivery. PURPOSE: To examine the effects of exposure to music during labor on the mode of delivery and parturients' stress levels. METHODS: This prospective, interventional study included 124 low-risk women who were recruited during latent phase of their first labor after epidural anesthesia. Patients were grouped according to their preference to receive music intervention or not. The music intervention included two subgroups: soft classical music and rhythmic music. We evaluated cortisol levels in saliva as a surrogate for stress level and State-Trait Personality Inventory at enrollment and 1-3 h later in all women who were still in labor. Delivery and perinatal outcomes were collected from electronic medical records. Correlations between the music intervention and maternal and perinatal outcomes were evaluated. RESULTS: Spontaneous vaginal delivery was significantly more frequent among women listening to music compared to the non-music group (P = 0.035). A trend towards lower rates of cesarean delivery was noted in the music group (P = 0.08), with no difference in instrumental vaginal delivery rates. Stress levels, as measured by questionnaires and by cortisol levels, blood pressure and pulse rate, remained similar throughout the study. No differences were noted between the different genres of music when examining obstetric and perinatal outcomes and stress levels. CONCLUSION: Listening to music during labor, improves the likelihood of primiparas to have a vaginal delivery regardless of stress level. As this treatment is simple, easy, and harmless to administer, we suggest it may be offered to all patients during labor.

Perinatal outcomes of unplanned out-of-hospital deliveries: a case-control study.

PURPOSE: To compare the pregnancy and perinatal outcomes of unplanned home or car births vs. in-hospital deliveries. METHODS: A retrospective, case-control study of women who underwent unplanned out-of-hospital deliveries vs. in-hospital deliveries from 2004 through 2014. Matching was based on gestational age and parity in a ratio of 2:1. RESULTS: There were no significant differences between the groups regarding demographic criteria, prenatal care and delivery complications. Women who delivered out of hospital (n = 90) had significantly fewer cesarean deliveries (1.1 vs. 10.6%; p = 0.05) and operative deliveries (2.2 vs. 13.3%; p = 0.004) in their obstetrical history than did the control group (n = 180). Significantly more newborns delivered out of the hospital had polycythemia (25.6 vs. 1.7%; p < 0.0001) and hypothermia (3.3 vs. 0%; p = 0.036) compared to the control group. CONCLUSION: Women with unplanned out-of-hospital deliveries tend to have fewer complications in their previous deliveries. Higher rates of polycythemia and hypothermia require attention for neonates born out of the hospital.

Skin closure at cesarean delivery, glue vs subcuticular sutures: a randomized controlled trial.

BACKGROUND: The optimal choice of skin closure at cesarean delivery has not yet been determined. OBJECTIVE: This study compared wound complications and scar healing following cesarean delivery between 2 methods of skin closure: glue (Dermabond; Ethicon, Somerville, NJ) and monofilament (Monocryl; Ethicon) epidermal sutures. STUDY DESIGN: We conducted a randomized controlled trial in which pregnant women undergoing a scheduled cesarean delivery were randomly assigned to skin (epidermis) closure with glue or with a monofilament synthetic suture. The subcutaneous tissue was sutured for all patients. Outcome assessors were blinded to group allocation. Scars were evaluated >8 weeks. Primary outcome measures were Patient and Observer Scar Assessment Scale scores. Secondary outcome measures were surgeon satisfaction, duration of surgery, duration of hospitalization after the cesarean delivery, and complications of surgical site infection or wound disruption (hematoma or seroma). A sample of 104 women was needed to achieve a clinically significant effect with a power of 80%. RESULTS: Demographic characteristics, patients' clinical background, prepregnancy body mass index, and subcutaneous thickness were similar in both groups. Length of surgery between the groups (37 ± 10 minutes for glue vs 39 ± 13 minutes for sutures, P = .515) was similar. Scores immediately after the wound closure were similar for both groups regarding surgeons' time estimate of closure (P = .181) and closure appearance (P = .082). Surgeons' satisfaction with the technique was significantly higher in the suture group (P = .003). No significant differences were found between the groups in blood loss, surgical site infection, length of postpartum hospitalization, or wound disruption. Glue and suture skin closure scores using Patient and Observer Scar Assessment Scale were similar 8 weeks after surgery, at P = .710 for patients and P = .568 for a physician observer. CONCLUSION: Skin closure using glue or a monofilament synthetic suture had similar results. Both methods were shown to be safe and successful for skin closure after a scheduled cesarean delivery and, therefore, can be used based on surgeon and patient preferences.

Long-term follow-up of congenital anomalies of the kidney and urinary tract diagnosed in utero: a longitudinal study.

BACKGROUND: Congenital-anomalies of the kidney-and-urinary-tract (CAKUT) are diagnosed in 3-6 per 1000 live-births. The objective of the current study was to examine the short and long-term outcomes of children diagnosed prenatally with CAKUT. METHODS: A retrospective study was performed in 2018 on all pregnancies diagnosed with CAKUT between 2004 and 2008 at our hospital. Pregnancy outcomes and long-term morbidity were evaluated. Comparison was made between mild and severe forms of CAKUT and between unilateral and bilateral anomalies. RESULTS: Ninety-eight children were included in the study. Most of them were born with an adequate weight for gestational-age, and were born at term by vaginal-deliveries. Children with major renal anomalies suffered significantly more frequently from recurrent UTIs (33.3% vs. 8.4%), needed more preventive antibiotics (50% vs. 20.5%), and had more renal surgeries (75% vs. 28%) than those with milder forms of CAKUT. Significantly more children with polycystic/multicystic kidney disease had recurrent UTIs (50% compared to 25% of the children with renal agenesis, and 5.6% of the children with hydronephrosis/hydroureter). There were no significant differences in the need for neurodevelopmental follow-up between the different groups of severity. Unilateral CAKUT patients required longer periods of nephrologist follow-up and repeated sonographic exams compared to bilateral CAKUT patients. Children with bilateral CAKUT more often needed special educational support than peers with unilateral disease (29.4% vs. 11.1%, P = 0.03). CONCLUSIONS: Pregnancies whose children are diagnosed with CAKUT in utero usually deliver at term, with adequate-weight for gestational-age. The most common long-term comorbidities in children were recurrent UTIs and the use of preventive antibiotics was often needed. Expecting couples can be reassured of a generally good outcome of their children, at least during the first decade of life.

The yield of chromosomal microarray analysis among pregnancies terminated due to fetal malformations.

BACKGROUND: Chromosomal microarray analysis (CMA) is preferred for genetic work-up when fetal malformations are detected prenatally. OBJECTIVES: To assess the detection rate of CMA after pregnancy termination due to abnormal ultrasound findings. METHODS: CMA was successfully performed in 71 pregnancies using fetal DNA (mainly from skin) or placenta. Data regarding clinical background, pregnancy work-up, and CMA were analyzed. RESULTS: Findings were abnormal in 17 cases (23.9%), of which 13 were detectable by karyotype. The incremental yield of CMA was 4/71 (5.6%); 1/32 (3.1%) for cases with an isolated anomaly and 3/39 (7.7%) for cases with nonisolated anomalies. CONCLUSIONS: CMA yield from terminated pregnancies was 23.9%. Although most chromosomal abnormalities are detectable by karyotype, CMA does not require viable dividing cells; hence, it is more practical for work-up after termination. In most cases, the diagnosis was followed by consultation regarding the risk of recurrence and recommendations for testing in subsequent pregnancies.

High physical activity and ovarian reserve: a prospective study of normo-ovulatory professional athletes.

BACKGROUND: This study investigated whether high physical activity affects ovarian reserve in normo-ovulatory, reproductive-age women. METHODS: This prospective, observational study compared 31 professional female athletes, with 31 women who did not engage in physical activity. It was conducted 2017-2020 in a tertiary medical center. Normo-ovulatory, professional athletes, ages 20-35 years were recruited from The Wingate Institute-the Israeli National Institute for Sport Excellence. They had high International Physical Activity Questionnaire (IPAQ) scores. Non-physically active women, matched by age and body mass index, were recruited from hospital staff. Women were evaluated for ovarian reserve markers on day 2-5 of the menstrual cycle, including follicular stimulating hormone, antral follicle count, anti-Mullerian hormone and Inhibin B. RESULTS: The average age of the high physical activity group was 29.9 ± 4.2 years and the nonactive group 31.6 ± 4.2 years (p = 0.062). Body mass index of both groups were similar (22.5 ± 5.0 vs. 21.4 ± 2.5, respectively; p = 0.1). No differences were observed with respect to follicle stimulating hormone (p = 0.12) and anti-Mullerian hormone (p = 0.16). A trend towards higher total antral follicle count in the high physical activity group vs. the non-active group (34.5 ± 12.9 vs. 28.1 ± 15.2, p = 0.08) and lower Inhibin B (68.1 ± 36.8 vs. 89.4 ± 46.1, p = 0.05). Menarche age correlated with anti-Mullerian hormone (r = 0.387, p = 0.003), as did total antral follicle count (r = 0.368, p = 0.004). IPAQ scores and basal follicle stimulating hormone levels were negatively correlated (r = - 0.292, p = 0.005). CONCLUSIONS: Athletic, normo-ovulatory women have ovarian reserves that are at least as good as those of the general population. As this is the first study examining this issue, it could cautiously reassure women engaged in high physical activity regarding ovarian reserve.

The possibility of integrating motile sperm organelle morphology examination (MSOME) with intracytoplasmic morphologically-selected sperm injection (IMSI) when treating couples with unexplained infertility.

PURPOSE: To examine the efficacy of motile sperm organelle morphology examination (MSOME) and intracytoplasmic morphologically-selected sperm injection (IMSI) for unexplained infertility. METHODS: This historical study, included 271 couples with primary, unexplained infertility/male subfertility, treated at an outpatient, IVF clinic, 2015-2018. These couples underwent MSOME after ≥3 failed intrauterine insemination (IUI) cycles and ≥1 failed IVF-ICSI cycle. They proceeded to intracytoplasmic morphologically-selected sperm injection (IMSI) within 6 months of MSOME. IMSI is conducted on the day of oocyte pick-up with a fresh semen sample. Pregnancy and delivery rates were analyzed. RESULTS: The cohort was divided based on percentage of normal cells at MSOME: Group A included 55 with no normal cells, Group B, 184 with 0.5%≤ normal cells ≤1.5% and Group C, 32 with ≥2% normal cells. Normal spermatozoa were found in 49 (89%) of Group A after extensive search. Group A had higher pregnancy rate (62.7%) compared to B (47.2%, P = 0.05) and C (28.1%, P = 0.002). Group B had higher pregnancy rate than C (p = 0.045). Delivery rate was higher in Group A (52.1%) compared to B (34.1%, p = 0.023) and C (21.9%, p = 0.007). Pregnancy and delivery rates were higher in A compared to B+C (p = 0.018, p = 0.01, respectively). CONCLUSIONS: MSOME may be useful for evaluating unexplained infertility. IMSI can be recommended for men with <2% normal spermatozoa at MSOME.

The Risk of Preterm Birth in Women with Three Consecutive Deliveries-The Effect of Number and Type of Prior Preterm Births.

Background: We aimed to explore the association of the number, order, gestational age and type of prior PTB and the risk of preterm birth (PTB) in the third delivery in women who had three consecutive singleton deliveries. Methods: A retrospective cohort study of all women who had three consecutive singleton births at a single medical center over a 20-year period (1994-2013). The primary outcome was PTB (<37 weeks) in the third delivery. Results: 4472 women met inclusion criteria. The rate of PTB in the third delivery was 4.9%. In the adjusted analysis, the risk of PTB was 3.5% in women with no prior PTBs; 10.9% in women with prior one PTB only in the first pregnancy; 16.2% in women with prior one PTB only in the second pregnancy; and 56.5% in women with prior two PTBs. A similar trend was observed when the outcome of interest was spontaneous PTB and when the exposure was limited to prior spontaneous or indicated PTB. Conclusions: In women with a history of PTB, the risk of recurrent PTB in subsequent pregnancies is related to the number and order of prior PTBs. These factors should be taken into account when stratifying the risk of PTB.

Fertility outcomes after extended searches for ejaculated spermatozoa in men with virtual azoospermia.

OBJECTIVE: To assess the fertility outcomes of extended searches for ejaculated spermatozoa in men with virtual azoospermia. DESIGN: A retrospective cohort of 242 couples whose male partner suffered from nonobstructive azoospermia and who were treated with the use of intracytoplasmic sperm injection (ICSI). SETTING: Not applicable. PATIENT(S): One hundred forty patients were referred to an extended search in the ejaculate and 102 patients were referred to microsurgical testicular sperm extraction (microTESE). INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Rates of sperm retrieval, fertilization, and pregnancy, take-home baby rate, and missed abortion rate were analyzed and compared. RESULT(S): In the ejaculated spermatozoa group, motile spermatozoa were retrieved in 91 cases (65%) and on oocyte pick-up day in 71 cases (78%), compared with 70 cases (68%) in the microTESE group, with a similar incidence of sperm retrieval between groups. No significant difference was found between groups regarding mean number of embryo transfer and fertilization and pregnancy rates. There was no significant difference between groups regarding take-home baby rate. A significantly higher first-trimester missed abortion rate was found in the ejaculated sperm group (n = 14; 52%) compared with the microTESE group (n = 3; 8.6%). CONCLUSION(S): Conducting an extended spermatozoa search in the ejaculate of men with virtual azoospermia can provide pregnancy rates similar to those obtained with the use of microTESE, with a higher rate of spontaneous abortions in the ejaculate group.

Predictors of twin pregnancy after ovarian stimulation and intrauterine insemination in women with unexplained infertility.

Multi-foetal gestation is a well-known, adverse outcome of infertility treatment. Maternal and obstetrical complications are more frequent in multiple pregnancies compared to singletons. The aim of this study was to determine parameters that affect the risk for multiple pregnancies after ovarian stimulation (OS) with intrauterine insemination (IUI). We retrospectively evaluated all cases of OS with IUI cycles that ended with successful clinical pregnancy. A total of 259 pregnancies were analysed (175 singletons, 63 twins and 21 triplets). Significant parameters predicting multiple pregnancies were gravidity and number of follicles at least 15 mm in diameter on day of hCG. A previous pregnancy increased the risk for multiple gestation by a factor of 1.86 (95% CI 1.03-3.37, p = 0.04). Each follicle ≥15 mm increased the odds ratio for multiple gestation by 1.3 (95% CI 1.03-1.65, p = 0.027). In conclusion, women with more than one previous pregnancy and three or more than three follicles ≥15 mm at hCG are at risk for multi-foetal pregnancy after OS and IUI.

Maternal nutrition and offspring's adulthood NCD's: a review.

Overnutrition and undernutrition during pregnancy are closely related to pregnancy outcome as well as neonatal and perinatal outcomes. This and more, from various published data it seems that the effect of maternal nutrition during fetal life stretches far beyond the neonatal period, and influences health issues in adulthood, from cardiovascular and metabolic disorders through mental illnesses. The purpose of this review is to update about overnutrition and undernutrition during pregnancy and their effect on noncommunicable adulthood diseases, and about leading theories on the subject.

Obstetric and perinatal outcomes in women with eating disorders.

BACKGROUND: We wished to investigate whether women with a history of eating disorders have an increased risk for adverse obstetric and perinatal outcomes. STUDY DESIGN: A retrospective study was conducted comparing pregnancy complications in patients with and without eating disorders. Deliveries occurred during the years 1988-2009 in a tertiary medical center. Women lacking prenatal care and with multiple gestations were excluded from the study. Stratified analyses were performed using multivariable logistic regression models. Odds ratios (OR) and their 95% confidence interval (CI) were computed. A p value<0.05 was considered statistically significant. RESULTS: During the study period, of 117,875 singleton deliveries, 122 (0.1%) occurred in patients with eating disorders. Eating disorders were significantly associated with fertility treatments (5.7% vs. 2.8%, p=0.047), intrauterine growth restriction (7.4% vs. 2.3%, p<0.001), term low birth weight (<2500 g) (7.4% vs. 2.8%, p=0.002), preterm delivery (15.6% vs. 7.5%, p=0.002), and cesarean delivery (25.4% vs. 15.0%, p=0.001). Using multivariable analyses, low birth weight (OR 2.5, 95% CI 1.3-5.0), preterm delivery (OR 2.2, 95% CI 1.4-3.6), and cesarean section (OR 1.9, 95% CI 1.3-2.9) were significantly associated with eating disorders. CONCLUSIONS: Eating disorders are associated with increased risk of adverse pregnancy outcomes. Accordingly, careful surveillance is needed for early detection of possible complications.
