RESUMEN

BACKGROUND: Gestational diabetes mellitus should be treated adequately to avoid maternal hyperglycemia-related complications. Previously, probiotic supplements were suggested to improve fasting blood glucose in women with gestational diabetes mellitus. However, a major limitation of previous studies was that preprandial and especially postprandial glucose values, which are important predictors of pregnancy outcomes, were not studied. OBJECTIVE: This study aimed to examine the effect of a mixture of probiotic strains on maternal glycemic parameters, particularly preprandial and postprandial glucose values and pregnancy outcomes among women with gestational diabetes mellitus. STUDY DESIGN: A multicenter prospective randomized, double-blind, placebo-controlled trial was conducted. Women newly diagnosed with gestational diabetes mellitus were randomly allocated into a research group, receiving 2 capsules of oral probiotic formula containing Bifidobacterium bifidum, B lactis, Lactobacillus acidophilus, L paracasei, L rhamnosus, and Streptococcus thermophilus (>6 × 109/capsule), and a control group, receiving a placebo (2 capsules/day) until delivery. Glycemic control was evaluated by daily glucose charts. After 2 weeks, pharmacotherapy was started in case of poor glycemic control. The primary outcomes were the rate of women requiring medications for glycemic control and mean daily glucose charts after 2 weeks of treatment with the study products. RESULTS: Forty-one and 44 women were analyzed in the treatment and placebo cohorts, respectively. Mean daily glucose during the first 2 weeks in the probiotics and placebo groups was 99.7±7.9 and 98.0±9.3 mg/dL, respectively (P=.35). The rate of women needing pharmacotherapy because of poor glycemic control after 2 weeks of treatment in the probiotics and placebo groups was 24 (59%) and 18 (41%), respectively (P=.10). Mean preprandial and postprandial glucose levels throughout the study period were similar between the groups (P>.05). There were no differences in maternal and neonatal outcomes, including birthweight and adverse effect profile between the groups. CONCLUSION: The oral probiotic product tested in this study did not affect glycemic control of women with gestational diabetes mellitus.

RESUMEN

OBJECTIVE: Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), ranges from asymptomatic to severe infection. We aimed to compare the prevalence of COVID-19 in asymptomatic pregnant versus nonpregnant women in order to establish recommendations for a COVID-19 screening strategy. METHODS: A prospective multicenter cohort study was conducted. Asymptomatic pregnant or nonpregnant women after March 2020 (the time when COVID-19 was first detected in north Israel) were tested for SARS-CoV-2 using nasopharyngeal reverse transcription polymerase chain reaction test, anti-nucleocapsid IgG, and anti-spike IgG. Diagnosis was made if at least one test result was positive. Pregnant women were tested between 34 and 42 weeks, mostly at birth. RESULTS: Among the 297 participating women, 152 were pregnant and 145 were nonpregnant. The prevalence of asymptomatic COVID-19 was similar between the groups (4 [2.6%] and 8 [5.5%], respectively; P = 0.2). All women with COVID-19 delivered healthy appropriate-for-gestational-age babies without malformations, at term. CONCLUSIONS: The rate of asymptomatic COVID-19 in pregnant women is low and comparable to the rate among nonpregnant women. Pregnancy outcomes are favorable. Future screening programs should consider that one of 25 screened asymptomatic women will be positive.

RESUMEN

BACKGROUND: The prevalence of women diagnosed with gestational diabetes mellitus (GDM) is increasing dramatically. Mobile technologies to enhance patient self-management offer many advantages for women diagnosed with GDM. However, to our knowledge, although mobile health (mHealth) and telemedicine systems for GDM management exist, evidence on their cultural and digital health literacy appropriateness levels is limited. OBJECTIVE: This review aimed to search and assess the literature on mHealth and telemedicine systems designed for women diagnosed with GDM. Our assessment of these technologies focused on their cultural and digital health literacy appropriateness as well as the systems' effectiveness in improving glycemic control and maternal and infant outcomes. METHODS: We conducted a scoping review using a framework adapted from Arksey and O'Malley. Four electronic databases were searched for relevant studies: PubMed, MEDLINE (EBSCO), Web of Science, and Scopus. The databases were searched between January 2010 and January 2022. The inclusion criteria were pregnant women diagnosed with GDM, use of telemedicine for monitoring and management, and vulnerable or disadvantaged patients. We used terms related to mobile apps and telemedicine: GDM, vulnerable populations, periphery, cultural appropriateness, and digital health literacy. Studies were screened and selected independently by 2 authors. We extracted the study data on a Microsoft Excel charting table and categorized them into final themes. The results were categorized according to the cultural and digital health literacy features presented. RESULTS: We identified 17 studies that reported on 12 telemedicine and mHealth app interventions. We assessed the studies in three domains: cultural appropriateness, digital health literacy, and maternal and infant outcomes. In the literature, we found that existing digital technologies may improve glycemic control and diabetes self-management. However, there is a lack of assessment of cultural and digital health literacy appropriateness for pregnant women diagnosed with GDM. Considerations in app design regarding cultural appropriateness were found in only 12% (2/17) of the studies, and only 25% (3/12) of the interventions scored ≥3 out of 5 in our assessment of digital health literacy. CONCLUSIONS: mHealth and telemedicine can be an effective platform to improve the clinical management of women with GDM. Although studies published on the use of mHealth and telemedicine systems exist, there is a limited body of knowledge on the digital health literacy and cultural appropriateness of the systems designed for women diagnosed with GDM. In addition, as our study was restricted to the English language, relevant studies may have been excluded. Further research is needed to evaluate, design, and implement better tailored apps regarding cultural and digital literacy appropriateness for enhancing pregnant women's self-management as well as the effectiveness of these apps in improving maternal and infant health outcomes.

RESUMEN

OBJECTIVE: To explore maternal humoral immune responses to SARS-CoV-2 infection and the rate of vertical transmission. METHODS: A prospective cohort study was conducted at two university-affiliated medical centers in Israel. Women positive for SARS-CoV-2 reverse-transcription-polymerase-chain-reaction (RT-PCR) test during pregnancy were enrolled just prior to delivery. Levels of anti-SARS-CoV-2 spike-IgM, spike IgG, and nucleocapsid IgG were tested in maternal and cord blood at delivery, and neonatal nasopharyngeal swabs were subjected to PCR testing. The primary endpoint was the rate of vertical transmission, defined as either positive neonatal IgM or positive neonatal PCR. RESULTS: Among 72 women, 36 (50%), 39 (54%) and 30 (42%) were positive for anti-spike-IgM, anti-spike-IgG, and anti-nucleocapsid-IgG, respectively. Among 36 neonates in which nasopharyngeal swabs were taken, one neonate (3%, 95% confidence interval 0.1-15%) had a positive PCR result. IgM was not detected in cord blood. Seven neonates had positive IgG antibodies while their mothers were seronegative for the same IgG. Anti-nucleocapsid-IgG and anti-spike-IgG were detected in 25/30 (83%) and in 33/39 (85%) of neonates of seropositive mothers, respectively. According to the serology test results during delivery with respect to the time of SARS-CoV-2 infection, the highest rate of positive maternal serology tests was 8 to 12 weeks post-infection (89% anti-spike IgG, 78% anti-spike IgM, and 67% anti-nucleocapsid IgG). Thereafter, the rate of positive serology tests declined gradually; at 20 weeks post-infection, only anti-spike IgG was detected in 33 to 50%. DISCUSSION: The rate of vertical transmission of SARS-CoV-2 was at least 3% (95% confidence interval 0.1-15%). Vaccination should be considered no later than 3 months post-infection in pregnant women due to a decline in antibody levels.

RESUMEN

BACKGROUND: To investigate late follicular progesterone (P) serum level in women with low number of pre-ovulatory follicles in the assisted reproductive technologies (ART) setting. METHODS: Fifty-five consecutive women having four or less pre-ovulatory follicles of >14 mm on the day of human chorionic gonadotropin (hCG) administration were prospectively evaluated. Spearman correlation tests between serum estradiol (E2) level, serum P level, P/E2 ratio, number of pre-ovulatory follicles, oocytes and embryos were performed. Women enrolled were further divided into two groups in accordance with the P/E2 ratio on the day of hCG administration and compared. RESULTS: Serum E2 level correlated positively with P serum level (rs = 0.36, P < 0.01), number of mature follicles (rs = 0.50, P < 0.01) and number of oocytes retrieved (rs = 0.36, P < 0.05), whereas negatively with P/E2 ratio (rs = - 0.68, P < 0.01). Likewise, number of pre-ovulatory follicles correlated positively with E2 level (rs = 0.50, P < 0.01), P level (rs = 0.27, P < 0.05) and number of oocytes retrieved (rs = 0.33, P < 0.05), while it correlated negatively with P/E2 ratio (rs = - 0.33, P < 0.05). Furthermore, women with P/E2 ratio > 1 on the day of hCG administration received considerably higher total follicular stimulating hormone (FSH) dosage and achieved significantly lower number of oocytes and embryos as compared to controls. CONCLUSIONS: The reverse relationship between number of pre-ovulatory follicles and P/E2 ratio implies that P rise is not only the result of increased steroidogenic activity but other oocytefollicle disrupted mechanisms seems to be involved. An exaggerated FSH stimulation appears to disrupt further these mechanisms.

RESUMEN

PURPOSE: Protein C global assay tests the global function of the protein C pathway, the most clinically significant anticoagulant pathway in humans. The objective of this study is to assess the difference in protein C global assay levels, throughout twin gestation, in naturally conceiving and ART-treated women. METHODS: This is a prospective cohort longitudinal study of pregnant women with twin gestation. Protein C Global evaluation was performed on frozen blood samples. Ninety-eight women with twin pregnancy, thirty-eight naturally conceived and sixty following ART, were evaluated on four occasions: during the first, second, and third trimesters, and 6 weeks or later after delivery (baseline). RESULTS: Protein C global assay levels were lower throughout pregnancy as compared to basal levels in both the naturally conceived and ART-conceived groups. However, protein C global assay levels were similar between the ART-conceived and naturally conceived twin pregnancies in all three trimesters. Perinatal complications were associated with decreased protein C global assay levels during the third trimester, although no difference was encountered between naturally conceived and ART-complicated twin pregnancies. CONCLUSION: While protein C global assay levels drop during twin pregnancy, there is no difference between ART-conceived and naturally conceived gestations. Decreased levels of protein C global assay during the third trimester were similarly associated with perinatal complications in both groups. Our results imply that twin pregnancy of itself is a more dominant factor for perinatal complications as compared to other factors, such as subfertility or the exposure to ART per se.

RESUMEN

BACKGROUND: Mycoplasma and Ureaplasma have been extensively studied for their possible impact on pregnancy, and their involvement in newborn diseases. This work examined Mycoplasma and Ureaplasma carriage among gravidas women and newborns in Israel, as well as associations between carriage and demographic characteristics, risk factors, pregnancy outcomes, and newborn morbidity rates. METHODS: A total of 214 gravidas women were examined for vaginal pathogen carriage through standard culture and polymerase chain reaction assay. Pharyngeal swabs were collected from newborns of carrier mothers. Clinical and demographic data were collected and infected newborn mortality was monitored for 6 months. RESULTS: Nineteen mothers were carriers, with highest prevalence among younger women. Pathogen carriage rates were 2.32% for Mycoplasma genitalium (Mg), 4.19% for Ureaplasma parvum (Up) and 2.32% for Ureaplasma urealyticum (Uu). Arab ethnicity was a statistically significant risk factor (p = 0.002). A higher prevalence was seen among women residing in cities as compared to villages. Thirteen (68%) newborns born to carrier mothers were carriers as well, with a higher prevalence among newborns of women delivering for the first time, compared to women that had delivered before. Infection rates among newborns were 20% for Mg (p = 0.238), 100% for Up (p < 0.01), and 28.5% for Uu (p = 0.058), with more male than female newborns being infected. No association was found between maternal carriage and newborn morbidity. CONCLUSIONS: Maternal Mycoplasma or Ureaplasma carriage may be associated with ethnicity and settlement type. Further studies will be needed to identify factors underlying these associations and their implications on delivery.

RESUMEN

OBJECTIVES: Guidelines recommend antibiotic treatment for every episode of asymptomatic bacteriuria throughout pregnancy in order to reduce maternal and fetal complications. We evaluated intra- and post-partum, as well as puerperal maternal and neonatal outcomes of an untreated group of pregnant women with asymptomatic bacteriuria at term. METHODS: This was a single center prospective cohort study. We enrolled women who came for labor or checkups, 37-42 weeks gestation, with singleton, vertex presentation. On admission, women gave a urine sample; we compared maternal, obstetric and neonatal data from the positive culture group to the negative culture. RESULTS: Among 248 pregnant women recruited, 205 negative and 32 positive urine cultures were collected. None of the women that participated in this study developed pyelonephritis during hospitalization or during the puerperium. No significant differences were detected between the two groups in terms of age, nulliparity, gestational age at delivery, length of hospitalization, birth type, intra- or post-partum fever, antibiotic treatment during labor or post-partum. CONCLUSIONS: No increased maternal or neonatal adverse effects were observed in women with untreated ASB detected at term.

RESUMEN

OBJECTIVES: (1) To compare the accuracy of vagino-rectal enriched culture (EC) and a rapid polymerase chain reaction (PCR) test for the detection of Group B streptococcus (GBS) carrier status at 35-37-week gestation and at onset of labor. (2) To assess the conversion rate of GBS carrier status between 35-37 weeks to the onset of labor according to the EC/PCR tests. A prospective study was performed at a women's health clinic, referred to give birth at one medical center. STUDY POPULATION: Low risk pregnant women at 35-37-week gestation who did not know their GBS carrier status. METHODS: Participants were evaluated for GBS status both at 35-37 weeks and at labor onset. Correlation between tests was calculated by Spearman correlation. RESULTS: One hundred and ten specimens were analyzed. Correlations: EC-PCR: 35-37 weeks - very high (r = 0.8), at labor - high (r = 0.5). EC-EC: 35-37 weeks and at labor - high (r = 0.39); PCR-PCR: 35-37 weeks and at labor- high (r = 0.7). CONCLUSIONS: Both the EC and Xpert PCR tests are accurate for detecting GBS carrier, both at 35-37 weeks and at labor onset. We did not detect a significant conversion of the GBS status from negative at 35-37 weeks to positive at onset of labor.

RESUMEN

OBJECTIVE: The cornerstone of concerns over trial of labor after cesarean (TOLAC) is the risk of uterine rupture. The purpose of this study was to document the rate of uterine rupture during TOLAC and to delineate its severity and consequences. MATERIALS AND METHODS: We retrospectively collected the data on vaginal and cesarean deliveries after a previous cesarean section with specific emphasis on uterine rupture and dehiscence in our center from 2006 through 2013. RESULTS: 22,670 deliveries were registered, with 18.2% rate of cesarean section. 2890 women had a single cesarean scar; of them 1206 delivered vaginally and 194 were re-operated during unsuccessful TOLAC. Seven cases of uterine rupture and 16 cases of dehiscence were recorded. There were no maternal, intrapartum or neonatal deaths, and no cesarean hysterectomy. There was one re-laparotomy, one ICU admission, and one blood transfusion; one neonate was admitted to NICU. TOLAC was successful in 86.1% of cases. CONCLUSIONS: Cautious selection and close monitoring of candidates are the cornerstones of successful management of TOLAC. Readily available facilities for emergency cesarean delivery and concerted obstetrical team can save the mother and child from catastrophic complications.

RESUMEN

The aim of this study was to determine whether the route of extended-spectrum ß-lactamase (ESBL) transmission to hospitalized newborns was from their mothers during delivery. Neonatal intensive care unit (NICU) hospitalized newborns were sampled for ESBL presence by stool cultures on the first and fourth days of life. Mothers of ESBL-positive newborns were sampled for possible correlation detection. Bacteria isolates were molecularly identified and susceptibility tests for antibiotic agents were performed. Of the 225 newborns, 14 (6.2%) were ESBL positive, 10 (4.4%) were Escherichia coli positive, and 4 (1.7%) were Klebsiella pneumoniae positive. Among the 14 mothers of positive newborns, 13 (92.8%) were found ESBL positive and one mother of a newborn with E. coli carriage was found ESBL negative. Genes encoding for ESBL resistance were identified. Antibiotic sensitivity and resistance were tested. This study demonstrated that ESBL bacteria carrier neonates hospitalized in NICU may be a result of transmission from mother to baby during delivery.

RESUMEN

OBJECTIVE: Because of the known complications of fetal macrosomia, our hospital's policy has been to discuss the risks of shoulder dystocia and cesarean section (CS) in mothers with a sonographic estimated fetal weight (SEFW) ≥ 4,000 g at term. The present study was performed to determine the effect of this policy on CS rates and pregnancy outcome. STUDY DESIGN: We examined the pregnancy outcomes of the macrosomic (≥ 4,000 g) neonates in two cohorts of nondiabetic low risk women at term without preexisting indications for cesarean: (1) SEFW ≥ 4,000 g (correctly suspected macrosomia) and (2) SEFW < 4,000 g (unsuspected macrosomia). RESULTS: There were 238 neonates in the correctly suspected group and 205 neonates in the unsuspected macrosomia group, respectively. Vaginal delivery was accomplished in 52.1% of the suspected group and 90.7% of the unsuspected group, respectively, p < 0.001. There was no difference in the rates of shoulder dystocia. The odds ratio for CS was 9.0 (95% confidence interval, 5.3-15.4) when macrosomia was correctly suspected. CONCLUSION: The policy of discussing the risk of macrosomia with SEFW ≥ 4,000 g to women is not justified. A higher SEFW to trigger counseling for shoulder dystocia and CS, more consistent with American College of Obstetrics and Gynecology (ACOG) guidelines, should be considered.

RESUMEN

OBJECTIVE: Calponin, a specific smooth muscle contraction regulatory troponin-like protein, is present in large quantities in uterine smooth muscle. Serum troponin levels rise in acute myocardial infarction, and creatine phosphokinase levels rise at high physical activity, both due to destruction of cardiac and striated muscle fibers. We hypothesize that the active labor process may cause uterine smooth muscle cell damage, which may result in rising maternal serum calponin levels. This was a preliminary study, searching for a new biomarker for preterm labor. METHODS: The study group included laboring term primiparous women with a singleton fetus. The control group included similar demographic and pregnancy characteristics pregnant women not in labor. Maternal serum levels of calponin basic isoform were measured evaluated and compared in both groups. RESULTS: Study group included 100 pregnant women. Calponin serum levels were higher in the active labor (794 ± 974 ng/mL) than in the group not in labor (591 ± 587 ng/mL), although it did not reach statistical significance. Gender and neonatal weight were similar in the two study groups. CONCLUSIONS: Calponin serum levels showed moderate elevation during active labor, compared to the levels in a cohort of pregnant comparable women at the same gestational weeks but not in labor.

RESUMEN

INTRODUCTION: The aim of this study was to assess the effect of mild pressure applied on the abdominal wall by the ultrasound transducer on fetal cephalic indices. MATERIAL AND METHODS: We examined by ultrasound 60 fetuses of healthy women, at 20-24 weeks of pregnancy, during routine prenatal evaluation. For every fetus biparietal diameter and head circumference were measured, with and without applying mild pressure by the ultrasound transducer. The weight and gestational age (GA) were calculated. RESULTS: The pressure applied by the transducer had a significant effect on the cephalic indices and on the weight and GA evaluations (p < 0.001). Fetal positioning significantly affected the impact that applied pressure had on head circumference and on the weight evaluation derived from it (p < 0.05). DISCUSSION: Applied pressure by an abdominal ultrasound probe affects cephalic indices and the derived weight and GA estimations. This may lead to incorrect diagnoses or hide pathological findings. The effect of applied pressure depends on fetal positioning. The examiner must be aware of this effect when evaluating the results of the measurements.

RESUMEN

OBJECTIVE: To construct cross-sectional reference range of the penile length during pregnancy, measuring it from the proximal edge of the corpus cavernosum to the tip of the glans penis. METHODS: Fetal penile length was measured by high resolution transvaginal ultrasound at 14 to 16 weeks and by transabdominal ultrasound at 17 to 35 weeks' gestation. RESULTS: Fetal penile length increased significantly with gestational age (GA), from 7 mm at 14 weeks' to 50 mm at 35 weeks' gestation. Penile length measurements were strongly related to the biometric fetal measurements. CONCLUSIONS: A reference range of the fetal penile length was constructed, measured from the proximal edge of the corpus cavernosum to the tip of the glans penis at 14 to 35 gestational weeks. This reference range can assist in early identification of true penile maldevelopment, which obligate further diagnostic workup, as opposed to the benign disorder of buried or concealed fetal penis.

RESUMEN

OBJECTIVE: To determine the normal level of the conus medullaris (CM) of the spinal cord of normal fetuses at 20 to 24 weeks' gestation using abdominal sonography. METHODS: Using a 4 to 8 MHz ultrasound abdominal transducer, CM was imaged in the midsagittal plane with the fetal spine facing toward the transducer. The CM ending level was located by counting the vertebrae caudal starting at T12, which was identified by lowest fetal rib. The CM locations were defined according to their positions relative to the vertebrae. RESULTS: One hundred and ten consecutive pregnant women were included in the study. The CM was clearly demonstrated in 78 (71%) of these cases. Most of the scanned fetuses had the CM ending height adjacent to vertebrae L2, L2-3 inter-space and L3 (73/78, 93%). The L1-2, L2, L2-3, and L3 vertebral groups did not differ in mean gestational weeks, maternal age, or fetal gender. CONCLUSION: The level of the CM can be determined at 20 to 24 weeks' gestation in about 70% of fetuses. Most of the scanned fetuses had the CM ending height adjacent to vertebrae L2, L2-3 vertebral space, and L3 (73/78, 93%). When detected lower than the third lumbar vertebra it should prompt prenatal and postnatal surveillance.

RESUMEN

BACKGROUND: Numerous studies correlated maternal serum and fetal cord Leptin Levels in pregnancy with new born weight (NBW) and maternal body mass index (BMI). However, there are only a few published studies concerning amniotic fluid leptin and its possible relationship to fetal growth and NBW. OBJECTIVES: To correlate leptin and insulin in amniotic fluid and maternal serum collected at 16-20 gestational weeks to NBW. METHODS: This was an observational study in which maternal serum Leptin, insulin, and amniotic fluid Leptin and insulin, studied from 70 healthy pregnant women undergoing amniocentesis for karyotyping, at 16-20 weeks gestation. NBW was correlated with maternal BMI and leptin and insulin Levels in maternal serum and amniotic fluid. RESULTS: Maternal serum leptin was detected as the best predictor of NBW. Squared correlation coefficient, r2 = 0.09, was statistically significant (P < 0.01). Maternal BMI correlated significantly with serum Levels of insulin and leptin r2 = 0.16 and 0.27 respectively, P < 0.01. CONCLUSION: In normal pregnancies, amniotic fluid Leptin correlates partially with NBW. Maternal serum leptin correlates significantly with NBW.

RESUMEN

Congenital cardiac diverticula are transmural localized protrusions within the free wall of the ventricles. Right ventricular diverticula are rarely diagnosed during the fetal period, and due to their rarity, their natural history remains unclear. We present a case of prenatal diagnosis of right ventricular diverticulum at 22 weeks' gestation. No other pathological findings were detected, the pregnancy and delivery were uneventful, and the diverticulum disappeared before the age of 3 months. Echocardiography of the infant at 1 year of age revealed no cardiac diverticulum or any cardiac anomaly and showed normal heart function. Literature review of all cases published to date reveal good outcome of right ventricular diverticula. We suggest reassuring our patients about the good prognosis of this cardiac anomaly.

RESUMEN

The common management in most centers in cases of multiple pregnancies with preterm premature rupture of membranes (PPROM) before 22 weeks of gestation is termination of the pregnancy or the expectant approach. Expectant management of previable PPROM in twin pregnancies results in an increased rate of fetal and neonatal morbidity and mortality of both twins. Selective fetocide of the twin with early midtrimester rupture of membranes may improve the unfavorable pregnancy outcome of the remaining fetus. We report two successful cases of twin pregnancies complicated by extremely PPROM managed by selective fetocide of the affected twin, with an uneventful single pregnancy course and delivery of healthy newborns at 36 weeks of gestation.

RESUMEN

We evaluated the effectiveness of color and spectral Doppler examination of the ovarian vasculature flow, using transvaginal sonography (TVS) in 65 women prior to laparoscopy due to suspected ovarian torsion. There were 15 cases of ovarian torsion. In all of them, a pathology was detected by the color and spectral Doppler examination. Of the 50 patients without torsion at laparoscopy, one had abnormal Doppler studies. Color and spectral Doppler can demonstrate the presence or absence of arterial and venous flow in cases of suspected torsion of the ovary.
