Risk of thrombocytopenia in neonates of thrombocytopenic mothers.

OBJECTIVE: Maternal thrombocytopenia during pregnancy may occur due to several possible etiologies, with potential neonatal impact. The aim of the present study was to investigate whether there is a correlation between maternal and neonatal platelet count among women with thrombocytopenia during pregnancy. METHODS: A cross-sectional retrospective study (2012-2019) was conducted at a tertiary medical center. Complete blood count was routinely measured in all patients on admission to the delivery ward. Thrombocytopenia was defined as a platelet count below 150 K/µL. Clinical and outcome parameters of thrombocytopenic mothers and their newborns were collected from the electronic files and analyzed by severity of maternal thrombocytopenia. RESULTS: Of 45 385 women with a documented platelet count at admission, 2841 (6.24%) had thrombocytopenia: 2623 (5.7%) mild (100-149 K/µL), 207 (0.45%) moderate (50-99 K/µL), and 11 (0.02%) severe (<50 K/µL). Eight newborns had thrombocytopenia; corresponding rates by severity of maternal thrombocytopenia were 0.11%, 1.43%, and 18.18% (P = 0.04). None of the thrombocytopenic neonates had an intraventricular hemorrhage or other bleeding complications. The correlation between maternal and neonatal platelet counts was weak (Pearson r = 0.038; P = 0.046). CONCLUSION: We suggest that although the chances of neonatal thrombocytopenia are higher with worsening maternal thrombocytopenia, actual occurrence is rare, and the correlation is poor. Therefore, maternal thrombocytopenia cannot be regarded as a significant risk factor for neonatal thrombocytopenia. Neonatal platelet count should be obtained when maternal thrombocytopenia is autoimmune or less than 100 K/µL.

Risks of urgent cesarean delivery preceding the planned schedule: A retrospective cohort study.

PURPOSE: The aim of the study was to ascertain risk factors and outcomes of elective cesarean deliveries performed urgently prior to their scheduled date. METHODS: Women carrying a viable singleton fetus who were scheduled for elective cesarean delivery at a tertiary medical center between 2012-2020 were identified by retrospective database. Differences in maternal and neonatal parameters between those who ultimately required urgent cesarean delivery and those who underwent the procedure as scheduled were analyzed. RESULTS: Of 4403 women who met the inclusion criteria, 559 underwent urgent cesarean delivery before the scheduled date. On multivariate analysis, factors significantly associated with a risk of transformation to an urgent cesarean delivery were chronic hypertension (aOR 1.92, 95% CI 1.30-2.83 P = 0.001), antenatal corticosteroids administration (aOR 3.26, 95% CI 2.38-4.47, P <0.001), and contraindication for vaginal delivery as the reason for elective cesarean delivery (aOR 1.67, 95% CI 1.32-2.12, P <0.001). Neonates born via urgent cesareans had an increased risk of 1-minute Apgar <7 (6% vs. 1.7%, P <0.001), intensive care unit admission (6.6% vs. 2.5%, P <0.001); their mothers were at risk of postpartum hemorrhage (5.9% vs. 3%, P = 0.001). CONCLUSIONS: The present study sheds light on the risk factors and maternal and fetal morbidities associated with elective cesarean deliveries that become urgent before the originally scheduled date. Physicians should take this information into account when planning an optimal date for elective cesarean delivery.

Mobile Self-Operated Home Ultrasound System for Remote Fetal Assessment During Pregnancy.

Background: Mobile medical devices for self-patient use are a rapidly evolving section of telehealth. We examined the INSTINCT® ultrasound system, a portable, self-operated ultrasound device attached to a commercial smartphone for remote fetal assessment. We aimed to evaluate whether it is feasible to use remote fetal assessment during pregnancy. Materials and Methods: This is an observational noninterventional trial. We included women with a singleton fetus at 14 + 0 to 39 + 6 gestational weeks. Each participant received the device for a self-use period of 7-14 days and was instructed to perform one to three scans a day. Participants completed a self-assessment questionnaire to evaluate safety and usability (i.e., user experience and satisfaction). Each scan was evaluated for fetal heart activity, amniotic fluid volume, fetal tone, fetal body, and breathing movements. Results: One hundred women, completing 1,360 self scans, used the device for 8.1 ± 1.5 days, performing an average of 13.6 ± 6.2 scans each. There were no device-related serious adverse events. Success in detection was 95.3% for fetal heart activity, 88.3% for body movements, 69.4% for tone, 92.2% for normal amniotic fluid volume, and 23.8% for breathing movements. Interobserver agreement was 94.4% for fetal heart rate activity, 85.9% for body movements, 69.5% for fetal tone, 86.9% for amniotic fluid volume, and 94.0% for breathing movements. Self-assessed user experience was rated at 4.4/5, whereas device satisfaction was rated at 3.9/5. Conclusion: The INSTINCT ultrasound system is a feasible solution for remote sonographic fetal assessment. Further studies are needed to assess its role and impact in telehealth antenatal care and fetal surveillance.

Maternal and perinatal outcomes in high compared to low risk pregnancies complicated by severe acute respiratory syndrome coronavirus 2 infection (phase 2): the World Association of Perinatal Medicine working group on coronavirus disease 2019.

BACKGROUND: It has still to be ascertained whether severe acute respiratory syndrome coronavirus 2 infection in pregnancy is associated with worse maternal and fetal outcomes compared to low risk gestations. OBJECTIVE: This study aimed to evaluate maternal and perinatal outcomes in high- and low-risk pregnancies complicated by severe acute respiratory syndrome coronavirus 2 infection. STUDY DESIGN: This was a multinational retrospective cohort study involving women with laboratory-confirmed severe acute respiratory syndrome coronavirus 2 infection from 76 centers from 25 countries in Europe, the United States, South America, Asia, and Australia from April 4, 2020, to October 28, 2020. The primary outcome was a composite measure of maternal mortality and morbidity, including admission to the intensive care unit, use of mechanical ventilation, or death. The secondary outcome was a composite measure of adverse perinatal outcome, including miscarriage, fetal loss, neonatal and perinatal death, and admission to the neonatal intensive care unit. All outcomes were assessed in high- and low-risk pregnancies. Pregnancies were considered high risk in case of either preexisting chronic medical conditions in pregnancy or obstetrical disorders occurring in pregnancy. The Fisher exact test and logistic regression analysis were used to analyze the data. RESULTS: A total of 887 singleton pregnancies who tested positive for severe acute respiratory syndrome coronavirus 2 infection using reverse transcription-polymerase chain reaction of nasal and pharyngeal swab specimens were included in the study. The risk of composite adverse maternal outcomes was higher in high-risk pregnancies than in low-risk pregnancies (odds ratio, 1.52; 95% confidence interval, 1.03-2.24; P=.035). In addition, women carrying high-risk pregnancies were at higher risk of hospital admission (odds ratio, 1.48; 95% confidence interval, 1.07-2.04; P=.002), presence of severe respiratory symptoms (odds ratio, 2.13; 95% confidence interval, 0.41-3.21; P=.001), admission to the intensive care unit (odds ratio, 2.63; 95% confidence interval, 1.42-4.88), and invasive mechanical ventilation (odds ratio, 2.65; 95% confidence interval, 1.19-5.94; P=.002). When exploring perinatal outcomes, high-risk pregnancies were at high risk of adverse perinatal outcomes (odds ratio, 1.78; 95% confidence interval, 0.15-2.72; P=.009). However, such association was mainly because of the higher incidence of miscarriage in high-risk pregnancies compared with that in low-risk pregnancies (5.3% vs 1.6%, P=.008); furthermore, there was no difference in other explored outcomes between the 2 study groups. At logistic regression analysis, maternal age (odds ratio, 1.12; 95% confidence interval, 1.02-1.22; P=.023) and high-risk pregnancy (odds ratio, 4.21; 95% confidence interval, 3.90-5.11; P<.001) were independently associated with adverse maternal outcomes. CONCLUSION: High-risk pregnancies complicated by severe acute respiratory syndrome coronavirus 2 infection were at higher risk of adverse maternal outcomes than low-risk pregnancies complicated by severe acute respiratory syndrome coronavirus 2 infection.

Schizophrenia and Sex Hormones: What Is the Link?

The involvement of gonadal hormones in the pathogenesis of schizophrenia has long been suspected because the psychosis differs in women and men and the illness first makes its appearance shortly after puberty. Changes in sex hormones have been linked with increased vulnerability to mood disorders in women, while testosterone have been associated with increased sexual drive and aggressiveness in men as well as women. Some studies have found abnormal levels of estrogens and testosterone in schizophrenia patients, but the results have been inconsistent and sometimes attributed to the hyperprolactinemia effect of antipsychotics, which may interfere with sex hormones production. The purpose of this review is to present the current knowledge on the link between blood levels of sex-hormones in women during the various stages of the female reproductive life (i.e. puberty, menstrual cycle, pregnancy, contraception, and menopause) and the course of schizophrenia. We also attempt to optimize the clinical approach to women with schizophrenia at these different stages.

Induction of labor in cases of late preterm isolated oligohydramnios: is it justified?

OBJECTIVES: To analyze in a retrospective cohort study the outcomes of pregnancies with isolated oligohydramnios at the late preterm period (34-36.6 weeks of gestation). STUDY DESIGN: This retrospective cohort study included three groups of women: (1) Women with isolated oligohydramnios whose pregnancy was managed conservatively (n = 33 births); (2) women with isolated oligohydramnios who were managed actively (i.e. induction of labor) (n = 111 births); and (3) a control group including women with normal amount of amniotic fluid who had a spontaneous late preterm delivery (n = 10,445 births). Maternal and fetal characteristics and obstetrics outcomes were collected from a computerized database of all deliveries at Soroka University Medical Center during the study period. RESULTS: Our cohort included 10,589 births. The rate of inducing labor was higher in the oligohydramnios groups compared to the controls (p < .001). There was an increase in the rate of cesarean section (CS) in the conservative treatment group (p < .001), compared with the other groups. Conservative management was associated with higher rates of maternal infection (p = .026), chorioamnionitis (p = .01), and transitory tachypnea of the newborn (p = .02). After controlling for confounding factors, mal presentation (OR = 19.9), and a prior CS (OR = 2.4) were independently associated with an increased risk for CS, while induction of labor was associated with a reduced risk for CS (OR = 0.28). CONCLUSIONS: Women with late preterm isolated oligohydramnios had a higher rate of induction of labor than women with a normal amount of amniotic fluid. Induction of labor seems to be beneficial to both the neonate and the mother as seen by a lower rate of CS conducted in this group, as well as lower maternal and neonatal morbidity in comparison to the conservative group. Therefore, women with oligohydramnios at late preterm may benefit from induction of labor.

Treating schizophrenia during menopause.

OBJECTIVE: The aim of this review is to examine three questions: What are the risks and benefits of treating women with schizophrenia with hormone therapy (HT) at menopause? Should the antipsychotic regimen be changed at menopause? Do early- and late-onset women with schizophrenia respond differently to HT at menopause? METHODS: MEDLINE databases for the years 1990 to 2016 were searched using the following interactive terms: schizophrenia, gender, menopause, estrogen, and hormones. The selected articles (62 out of 800 abstracts) were chosen on the basis of their applicability to the objectives of this targeted narrative review. RESULTS: HT during the perimenopause in women with schizophrenia ameliorates psychotic and cognitive symptoms, and may also help affective symptoms. Vasomotor, genitourinary, and sleep symptoms are also reduced. Depending on the woman's age and personal risk factors and antipsychotic side effects, the risk of breast cancer and cardiovascular disease may be increased. Antipsychotic types and doses may need to be adjusted at menopause, as may be the mode of administration. CONCLUSIONS: Both HT and changes in antipsychotic management should be considered for women with schizophrenia at menopause. The question about differences in response between early- and late-onset women cannot yet be answered.

[THE EFFECT OF 5 DAYS IMMERSION IN DEAD SEA WATER ON BLOOD GLUCOSE LEVELS IN TYPE 2 DIABETES MELLITUS PATIENTS].

BACKGROUND: Body immersion in plain water or mineral water induces significant and unique physiological changes in most body systems. In a previous pilot study, a significant reduction in blood glucose levels among diabetes mellitus (DM) patients was found following a single immersion in Dead Sea water but not after immersion in plain water. OBJECTIVE: To study the immediate and long term effects of immersion in mineral water for five consecutive days on blood glucose in patients with type 2 DM. METHODS: A total of 34 patients with type 2 DM were divided into 2 groups: The first immersed in a plain water pool and the second immersed in a Dead Sea water pool; both pools were warmed to a temperature of 35°C. Immersions for 20 minutes occurred twice daily: two hours after breakfast and before dinner. Seven samples of capillary blood glucose levels were taken: fasting, before and after every immersion, prior to lunch and before bedtime. Hemoglobin A1C (HbA1c) was taken prior to the study and a re-check was conducted during the 12 weeks following the study. RESULTS: Blood glucose levels significantly decreased immediately after immersion both in Dead Sea water and plain water compared to their values prior to immersion (p<0.001). No significant difference was noted between both types of water. A decrease in fasting glucose levels was observed only in the group immersed in Dead Sea water when compared to plain water (6.83±5.68 mg/dl versus 4.37±1.79 respectively and the difference was close to statistical significance (p=0.071. There were no changes in HbA1c levels. CONCLUSION: Immersion for 20 minutes in water (Dead Sea or plain water) at a temperature of 35°C induced an immediate reduction in glucose levels in patients with type 2 DM.
