RESUMEN
PURPOSE: Obesity and preeclampsia share similar patho-mechanisms and can both affect placental pathology. We aimed to investigate pregnancy outcomes in correlation with placental pathology among pregnancies complicated by preeclampsia in three different maternal body mass index (BMI, kg/m2) groups. METHODS: In this retrospective cohort study, medical and pathological records of patients with preeclampsia and a singleton pregnancy delivered between 2008 and 2021 at a single tertiary medical center were reviewed. Study population was divided into three BMI groups: BMI < 22.6 kg/m2 (low BMI group), 22.7 ≤ BMI ≤ 28.0 kg/m2 (middle-range BMI group), and BMI > 28.0 kg/m2 (high BMI group). Data regarding maternal characteristics, neonatal outcomes, and placental histopathological lesions were compared. RESULTS: The study groups included a total of 295 patients diagnosed with preeclampsia-98, 99, and 98 in the low, middle-range, and high BMI groups respectively. Neonatal birth weight was significantly decreased in the low maternal BMI group compared to both middle and high BMI groups (p = 0.04) with a similar trend seen in placental weight (p = 0.03). Villous changes related to maternal malperfusion were more prevalent in the low and high BMI groups compared to middle-range BMI group (p < 0.01) and composite maternal vascular malperfusion lesions were also more prevalent in the groups of BMI extremities compared to the middle-range BMI group (p < 0.01). CONCLUSION: Maternal BMI might influence neonatal outcomes and placental pathology in pregnancies complicated by preeclampsia. Both extremes of BMI were associated with higher rates of placental maternal vascular malperfusion. Balanced BMI in women at risk for preeclampsia may reduce the incidence of placental lesions.
RESUMEN
STUDY OBJECTIVE: To identify risk factors for recurrent ovarian torsion and evaluation of the efficacy of oophoropexy techniques. DESIGN: Case control study. SETTING: Tertiary university-affiliated medical center. PATIENTS: A total of 79 women with recurrent ovarian torsion (study group) were matched with 158 women with a single episode of ovarian torsion (control group). INTERVENTIONS: Laparoscopic detorsion and oophoropexy. MEASUREMENTS AND MAIN RESULTS: Demographic data, clinical characteristics, ultrasound characteristics, surgical findings, surgical procedures, and torsion recurrence rates were analyzed and compared between the 2 groups between 2001 to 2020. RESULTS: There was an inverse association between women's age and the risk of recurrent torsion (adjusted odds ratio [aOR], 0.89; 95% confidence interval [CI], 0.83-0.96, p = .003). Moreover, in women younger than 20 years, the risk of recurrent event was substantially higher (aOR, 5.0; 95% CI, 1.56-6.15, p = .007). In addition, the absence of ovarian pathology was associated with increased risk for recurrent torsion (aOR, 14.3; 95% CI, 6.15-33.42; p <.001). Oophoropexy was performed in 46 women in the study group. The risk of recurrent torsion after oophoropexy was 30%. A long duration of pain before admission was associated with oophoropexy failure (37.5 ± 6.3 hours vs 11.7 ± 6.0 hours, p = .003). No single fixation procedure was superior to the others in terms of therapeutic success. CONCLUSION: Recurrent ovarian torsion is more common in young women with a normal-appearing ovary. Oophoropexy is a safe procedure with a risk of retorsion in 30% of the patients. We found no advantage for one fixation technique over the others.

Natural iron-rich mineral water (IRMW) is a supplement with a higher iron bioavailability than oral iron supplement tablets. Five (4%) of 116 women who consumed IRMW starting from 16 weeks of gestation were diagnosed as having isolated foetal echogenic bowel at a single community maternity clinic between 2012 and 2015. The workup of all the women was otherwise negative. Four women taking IRMW were re-checked after discontinuation of the supplement and had a normal-appearing foetal bowel. Our observations suggest that isolated echogenic bowel may be related to the consumption of IRMW, possibly due to the high absorption of iron, leading to the coating of the internal wall of the foetal bowel and subsequent appearance of an echogenic bowel. Although this finding appears free of harmful ramifications, its possible sonographic effects on the appearance of the foetal bowel should be considered in light of the increasing popularity of IRMW use.IMPACT STATEMENTWhat is already known on this subject? IRMW is a highly absorbed iron supplement. The differential diagnosis for foetal echogenic bowel is broad and requires thorough investigation. Iron is secreted through the maternal blood to the amniotic fluid, which is swallowed by the foetus, reaching its bowel.What do the results of this study add? IRMW consumption is a possible aetiology of an isolated foetal echogenic bowel in the second half of pregnancy, conveying no risk of foetal morbidity or mortality.What are the implications of these findings for clinical practice and/or further research? In light of the increasing popularity of IRMW, we believe that it is important to increase the level of awareness of the possible effects of its intake on the sonographic appearance of the foetal bowel.

BACKGROUND: Data on the optimal gestational weight gain in twin pregnancies are limited. As a result, the Institute of Medicine currently provides only provisional recommendations on gestational weight gain in this population. OBJECTIVE: This study aimed to identify the optimal range of gestational weight gain in twin pregnancies and to estimate the association between inappropriate gestational weight gain and adverse pregnancy outcomes. STUDY DESIGN: This was a retrospective cohort study of all women with twin pregnancies that were followed up in a single, tertiary center between 2000 and 2014. We used 2 approaches to identify the optimal range of gestational weight gain: a statistical approach (the interquartile range of gestational weight gain in low-risk pregnancies with normal outcomes) and an outcome-based approach (by identifying thresholds of gestational weight gain below or above which the rate of adverse outcomes increases). The primary outcome was preterm birth. Associations of gestational weight gain below or above the normal range with the study outcomes were estimated using logistic regression analysis and were expressed as adjusted odds ratio with 95% confidence intervals. These associations were stratified by prepregnancy body mass index group. RESULTS: A total of 1274 women with twin pregnancies met the study criteria: 43 were classified as underweight, 777 were normal weight, 278 were overweight, and 176 were obese. Our estimates of the optimal gestational weight gain range were similar to those recommended by the Institute of Medicine except for the obese category, in which our optimal gestational weight gain range at 37 weeks (9.3-16.3 kg) was lower than in the provisional Institute of Medicine recommendations (11.3-19.1 kg). Nearly half of our cohort experienced inappropriate gestational weight gain: 30% (n=381) gained weight below and 17% (n=216) gained weight above current Institute of Medicine recommendations. In the normal weight group, gestational weight gain below recommendations was associated with an increased risk of preterm birth and birthweight at the <10th centile and with a reduction in the risk of hypertensive disorders, whereas gestational weight gain above recommendations was associated with an increased risk of hypertensive disorders and a reduction in the risk of birthweight at the <10th centile. Associations were less consistent in the overweight and obese groups. CONCLUSION: These findings identify gestational weight gain as a potentially modifiable risk factor for preterm birth and other pregnancy complications in twin gestations. Further prospective studies are needed to determine whether interventions aimed at optimizing gestational weight gain can improve the outcomes of these high-risk pregnancies.

PURPOSE: Pregnancies conceived by in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) are associated with an increased incidence of obstetrical and neonatal complications. With the growing rate of male factor infertility, which is unique by not involving the maternal milieu, we aimed to assess whether obstetrical outcomes differed between IVF/ICSI pregnancies due to male factor infertility and those not due to male factor infertility. METHODS: A retrospective cohort study of women receiving IVF/ICSI treatments at a single hospital over a five-year period was involved in the study. Inclusion criteria were women with a viable pregnancy that delivered at the same hospital. Pregnancies were divided into male factor only related and non-male factor-related infertility. The groups were compared for several maternal and neonatal complications. RESULTS: In total, 225 patients met the study criteria, with 94 and 131 pregnancies belonging to the male factor and non-male factor groups, respectively. Demographic and clinical characteristics were comparable, except for younger maternal age and higher incidence of twin pregnancies in the male factor group. A sub-analysis for singleton pregnancies revealed a less likelihood of cesarean delivery, preterm birth, and male gender offspring in the male factor group (p < 0.05). These differences were not observed in the sub-analysis for twin pregnancies. Other outcome measures were similar in both groups, both for singleton and twin pregnancies. CONCLUSION: Singleton IVF pregnancies due to male factor infertility are associated with a reduced incidence of some adverse outcomes, likely due to lack of underlying maternal medical conditions or laboratory conditions related to ICSI. Our findings require validation by further studies on larger samples.

PURPOSE: To compare pregnancy outcomes in grand-multiparous (GMP) women with and without one previous cesarean delivery (CD), and to evaluate the number of previous successful vaginal deliveries after a CD needed to reduce the complication rate of trials of labor after a previous CD. METHODS: This is a retrospective cohort study of women with singleton pregnancy at term who had a trial of vaginal delivery between 2007 and 2014 at a tertiary medical center. We compared pregnancy outcomes in GMP women with and without one previous cesarean delivery. The primary outcome was mode of delivery and secondary outcomes were uterine rupture and composite maternal and neonatal morbidity. For the secondary objective, we compared pregnancy outcomes in women in TOLAC, stratified by the number of previous vaginal deliveries. RESULTS: Overall, 2815 GMP women met the study criteria, of which 310 (11%) had a previous cesarean delivery. The rate of a successful vaginal deliveries (VBAC) was similar, regardless of the presence of a previous cesarean delivery. No other differences in outcomes were found between the groups. In a secondary analysis, it was found that the presence of a single previous VBAC (compared to no previous VBACs) increased the odds of achieving a vaginal delivery in the next trial of labor after cesarean delivery (TOLAC) (aOR 5.66; 95% CI 3.73-8.60), and decreased the risk of maternal or neonatal adverse outcomes (aOR 0.62; 95% CI 0.39-0.97, and aOR 0.49; 95% CI 0.25-0.97, respectively). Multiple prior VBACs (as compared to a single prior VBAC) did not increase the odds of achieving another VBAC. CONCLUSION: Grand-multiparous women with and without previous uterine scar have comparable pregnancy outcomes. Additionally, after the first VBAC, additional successful VBACs do not improve the success rate in the next TOLAC.

OBJECIVE: Women with twins have an a priori increased risk for many of the complications associated with maternal obesity. Thus, the impact of maternal obesity in twins may differ from that reported in singletons. In addition, given the increased metabolic demands in twin pregnancies, the impact of maternal underweight may be greater in twin compared with singleton gestations. Our objective was to test the hypothesis that the relationship between maternal pre-pregnancy body mass index (BMI) and adverse pregnancy outcomes differ between twin and singleton gestations. METHODS: This was a retrospective population-based study of all women who had a singleton or twin hospital birth in Ontario, Canada, between April 2012 and March 2016. Data were obtained from the Better Outcomes Registry & Network (BORN) Ontario. The relationship between maternal BMI category and pregnancy complications was assessed separately in twin and singleton gestations. The primary outcome was a composite variable that included any of the following complications: preeclampsia, gestational diabetes, or preterm birth before 320/7 weeks. Relative risk (aRR) and 95% confidence intervals (CI) for adverse outcomes for each BMI category as defined by WHO (using normal weight category as reference) were generated using modified Poisson regression, adjusting for maternal age, nulliparity, smoking, previous preterm birth, and fetal sex. RESULTS: A total of 487,870 women with singleton (n = 480,010) and twin (n = 7860) pregnancies met the inclusion criteria. The risk of the composite primary outcome, preeclampsia, gestational diabetes, and cesarean delivery increased with high maternal BMI in both singleton and twin gestations, but these associations were weaker in twin compared with singleton gestations (association of BMI ≥ 40.0 kg/m2 with primary outcome: aRR = 3.10, 95%-CI 2.96-3.24 in singletons compared with aRR = 1.74, 95%-CI 1.37-2.20 in twins). In singleton pregnancies the risk of preterm birth at < 320/7 weeks increased with maternal BMI, mainly due to an increased risk of provider-initiated preterm birth. In twin gestations, however, underweight (but not overweight or obesity) was associated with the greatest risk of preterm birth at < 32 weeks (aRR 1.67, 95%-CI 1.17-2.37), mainly due to an increased risk of spontaneous preterm birth (aRR 2.10, 95%-CI 1.44-3.08). CONCLUSION: In healthy women with twin pregnancies, underweight is associated with the greatest risk for preterm birth, while the association of maternal obesity with adverse pregnancy outcomes is weaker than that observed in singletons.

PURPOSE: To compare pregnancy outcomes in women with pPROM and a cervical cerclage in whom the cerclage was removed within 24 h and those in whom the cerclage was retained in situ. METHODS: A two-center retrospective cohort study of women with a singleton gestation with pPROM at < 340/7 weeks of gestation in the presence of cervical cerclage (January 1, 2012-July 30, 2016). Maternal and perinatal outcomes were compared between women in whom cerclage was removed within 24 h from pPROM and those in whom cerclage was retained until the onset of delivery. The primary outcome was time from pPROM to delivery. RESULTS: Seventy women met inclusion criteria. Cerclage was left in situ in 47 (67.1%) and removed in 23 (32.9%) women. Women in the cerclage retention group had a higher pPROM-to-delivery interval (7.0 ± 7.2 vs. 6.0 ± 10.9 days, p = 0.03), and were more likely to have a latency period > 48 h (87.2% vs. 65.2%, p = 0.03; aOR 3.9, 95% CI 3.1-4.9) or > 7 days (29.8% vs. 8.7%, p = 0.04; aOR 7.0, 95% CI 2.5-19.6) compared with women in whom cerclage was removed. Furthermore, chorioamnionitis rate was lower in the cerclage retention group compared to cerclage removal group (aOR 0.7, 95% CI 0.5-1.0). There were no differences between the groups in early neonatal sepsis, severe brain injury, or composite neonatal outcome. CONCLUSION: In women with pPROM and cervical cerclage, retention of cerclage may be associated with a longer latency period, and a lower chorioamnionitis rate, without an associated increase in the risk of neonatal infectious morbidity. Presentation information: The abstract of this study was presented as a poster at the 38th SMFM (Society of Maternal and Fetal Medicine) annual meeting, February 2018, Dallas, Texas, USA.

BACKGROUND: Preeclampsia is among the most common medical complications of pregnancy. The clinical utility of invasive hemodynamic monitoring in preeclampsia (e.g., Swan-Ganz catheter) is controversial. Thoracic impedance cardiography (TIC) and Doppler echocardiography are noninvasive techniques but they both have important limitations. NICaS™ (NI Medical, PetachTikva, Israel) is a noninvasive cardiac system for determining cardiac output (CO) that utilizes regional impedance cardiography (RIC) by noninvasively measuring the impedance signal in the periphery. It outperformed any other impedance cardiographic technology and was twice as accurate as TIC. METHODS: We used the NICaS™ system to compare the hemodynamic parameters of women with severe preeclampsia (PET group, n = 17) to a cohort of healthy normotensive pregnant women with a singleton pregnancy at term (control group, n = 62) (1/2015-6/2015). Heart rate (HR), stroke volume (SV), CO, total peripheral resistance (TPR) and mean arterial pressure (MAP) were measured 15-30 min before CS initiation, immediately after administering spinal anesthesia, immediately after delivery of the fetus and placenta, at the abdominal fascia closure and within 24-36 and 48-72 h postpartum. RESULTS: The COs before and during the CS were significantly higher in the control group compared to the PET group (P < .05), but reached equivalent values within 24-36 h postpartum. CO peaked at delivery of the newborn and the placenta and started to decline afterwards in both groups. The MAP and TPR values were significantly higher in the PET group at all points of assessment except at 48-72 h postpartum when it was still significantly higher for MAP while the TPR only exhibited a higher trend but not statistically significant. The NICaS™ device noninvasively demonstrated low CO and high TPR profiles in the PET group compared to controls. CONCLUSIONS: The immediate postpartum period is accompanied by the most dramatic hemodynamic changes and fluid shifts, during which the parturient should be closely monitored. The NICaS™ device may help the clinician to customize the most optimal management for individual parturients. Our findings require validation by further studies on larger samples.

PURPOSE: To stratify maternal and neonatal outcomes of trials of labor after previous cesarean delivery (TOLAC) by gestational age. METHODS: Retrospective cohort study of all singleton pregnancies with one previous cesarean delivery in TOLAC at term between 2007 and 2014. We compared outcomes of delivery at an index gestational week, with outcomes of women who remained undelivered at this index gestational week (ongoing pregnancy). Odds ratios and 95% confidence intervals were adjusted for maternal age, previous vaginal delivery, induction of labor, epidural use, presence of meconium, and birth weight > 4000 g. RESULTS: Overall, 2849 women were eligible for analysis. Of those, 2584 (90.7%) had a successful TOLAC and 16 women (0.56%) had uterine rupture. Those rates did not differ significantly for any gestational age (GA) group. Following adjustment for possible confounders, GA was not found to be independently associated with adverse maternal or neonatal outcomes. CONCLUSION: Among women at term with a single previous cesarean delivery, GA at delivery was not found to be an independent risk factor for TOLAC success or uterine rupture. We suggest that GA by itself will not serve as an argument for or against TOLAC.

PURPOSE: Differences in hemodynamic changes during a cesarean section (CS) between twin and singleton pregnancies are poorly defined. The Non-Invasive Cardiac System (NICaS) is an impedance device that measures cardiac output (CO) and its derivatives. We compared maternal cardiac parameters using NICaS™ in singleton and twins before and during delivery, as well at the early puerperium in healthy women undergoing CS at term. METHODS: This prospective longitudinal study included women with twin (n = 27) or singleton pregnancies (n = 62) whose hemodynamic parameters were assessed by NICaS before an elective CS, after spinal anesthesia, immediately after delivery, after fascia closure, and within 24-36 and 48-72 h postpartum. RESULTS: By 24-36 h postpartum, the mean arterial pressure and the total peripheral resistance equaled preoperative values in both groups. The CO increased throughout the CS and peaked immediately after delivery in the singleton group (P < 0.0001), after which it abruptly began to decline until reaching a nadir 24-36 h after delivery (P < 0.0001), while it remained steady throughout the CS and then dropped until 24-36 h after delivery in the twin group (P < 0.05). None of the studied parameters differed significantly between the groups for the 24-36 and 48-72 h postpartum measurements. CONCLUSIONS: Hemodynamic parameters immediately before, during and shortly after CS in singleton and twin pregnancies are equivalent. Further evaluations of the value of NICaS™ in assessing cardiovascular-related pregnancy complications are warranted.

BACKGROUND: The association between antiphospholipid antibodies (aPL) and multiple sclerosis (MS) has been suggested previously, but prior studies provided contradicting findings. OBJECTIVES: To characterize the expression profile of eight classic and non-classic aPL in patients diagnosed with MS. METHODS: Using the BioPlex 2200 immunoassay, we measured the levels of serum immunoglobulin (Ig)M and IgG isotypes of three classic aPL and five non-classic aPL in 98 subjects with MS and 237 healthy controls. RESULTS: Three non-classic aPL were significantly more prevalent among MS patients in comparison to the control group. These antibodies included IgM and IgG against phosphatidylserine-ß2GPI (PS-B2), IgG prothrombin complex (PT-PT) and IgM prothrombin (PT). The positive results according to Bonferroni correction are PS-B2 IgG and PT-PT IgG. The remaining aPL profiles did not differ significantly between the two groups. CONCLUSIONS: An association between certain non-classic aPL and MS has been established. The specific role of these autoantibodies in the pathogenesis of the condition remains uncertain.

BACKGROUND: The pathogenesis of autoimmunity is presumed to be a complex process including genetic predisposition, hormonal balance and environmental factors such as infectious agents. Helicobacter pylori, a common bacterial infectious agent has been associated with a variety of autoimmune disorders. However, this bacteria is also thought to play a protective role in the development of multiple sclerosis (MS), systemic lupus erythematosus (SLE) and inflammatory bowel disease (IBD). We tested various links between anti-H. pylori (anti-HP) antibodies and a wide profile of autoimmune diseases and autoantibodies. METHODS: A total of 1290 patients diagnosed with 14 different autoimmune diseases from two geographical areas (Europe and Latin America) and two groups of healthy matching controls (n=385) were screened for the presence of H. pylori IgG antibodies by "pylori detect" kit. In parallel, a large profile belonging to three groups of autoantibodies was tested in all sera (anti-nuclear antibodies, autoantibodies associated with thrombophilia and gastrointestinal diseases). RESULTS: Our data demonstrate associations between anti-HP antibodies and anti-phospholipid syndrome, giant cell arteritis, systemic sclerosis and primary biliary cirrhosis. Our data also support a previously known negative association between the prevalence of anti-HP antibodies and IBD. Additionally, links were made between seropositivity to H. pylori and the presence of anti-nuclear antibodies, dsDNA, anti-Ro and some thrombophilia-associated antibodies, as well as negative associations with gastrointestinal-associated antibodies. CONCLUSIONS: Whether these links are epiphenomenal or H. pylori does play a causative role in the autoimmune diseases remains uncertain. The negative associations could possibly support the notion that in susceptible individuals infections may protect from the development of autoimmune diseases.

The identification of etiological factors in the induction of autoimmunity has remained elusive despite an enormous effort at dissection of the molecular structure of the target antigens and effector mechanisms. One characteristic feature of autoantigens is their repetitive structure as well as their conservation and evolution. Toxoplasma (T.) gondii is a primitive protozoan. We hypothesized that patients with autoimmune disease would have broad reactions against Toxoplasma antigens based on autoantigen conservation. To address this issue, we assessed serologic evidence of reactivity to Toxoplasma gondii along with a large profile of autoantibodies in patients with various autoimmune diseases (AID). We included sera of 1514 patients with 11 different AID collected from referral centers in Europe and Latin America as well as from 437 geographically matched controls, for the prevalence of anti Toxoplasma antibodies (ATxA) IgG and IgM and serum autoantibodies utilizing the BioPlex 2200 system (Bio- Rad Laboratories, USA). Serum ATxA IgG were positive in 42% of patients with AID versus 29% of controls (p < 0.0001). Among Europeans, ATxA IgG were associated with anti-phospholipid syndrome (APS; p < 0.0001), cryoglobulinemia (p < 0.0001), ANCA-associated vasculitides (p < 0.01), autoimmune thyroid diseases (p < 0.0001), systemic sclerosis (SSc; p < 0.0001) and rheumatoid arthritis (RA; p < 0.0001). Of note, Latin American RA sera exhibited similar frequency of ATxA IgG as controls. ATxA IgM were more prevalent in European patients with APS (p < 0.01), SSc (p < 0.05) and inflammatory bowel disease (IBD, p < 0.05) than in controls. Further, in AID patients the presence of ATxA correlated with autoantibodies characteristic of APS (anti- cardiolipin, B2GPI, complex of cardiolipin- B2GPI, prothrombin, phosphatydilethanolamine), and of SSc (anti-centromere, Scl-70). Our findings suggest that T. gondii may contribute to the pathogenesis of AID. This interaction may depend on or explain observed geoepidemiological variance in AID.

BACKGROUND: Currently not much is known regarding the environmental factors involved in primary biliary cirrhosis (PBC). It is even more unclear which factors may determine the subgroup (i.e., AMA status) of patients with PBC. We thus tested AMA+and AMA- PBC patients' sera for antibodies (Abs) against multiple infectious agents. METHODS: Sera from 69 patients with PBC (49 AMA+and 20 AMA-) and 100 matched controls were screened for IgG-Abs against Toxoplasma gondii, Helicobacter pylori, Epstein-Barr virus (EBV), cytomegalovirus (CMV), hepatitis B, and hepatitis C utilizing the BioPlex 2200 and ELISA kits (Bio-Rad Laboratories, USA). RESULTS: The prevalence of four anti-infectious agents Abs was significantly elevated among PBC patients when compared with controls, namely anti-T. gondii (ATxA; 71% vs. 40%, p<0.0001), EBV early antigen (EA; 44% vs. 12%, p<0.0001), H. pylori (54% vs. 31%, p<0.01), and CMV (90% vs. 75%, p<0.05) Abs, respectively. The co-occurrence of these four anti-infectious agents Abs was highly common in PBC, whereas this infection burden was rare in healthy subjects (20% vs. 3% respectively, p<0.0001). Furthermore, specific infections interactions possibly increasing PBC risk were noted as well. Seropositivity of ATxA was inversely associated with cirrhosis among PBC patients (p<0.05). Finally, no differences were observed between AMA- sera and their AMA+counterparts with regard to seroprevalence of any of the investigated infectious agents. CONCLUSIONS: We note the association of ATxA and PBC, with the possibility of a milder disease manifestation. We also suggest that multiple exposures to infectious agents may contribute to PBC risk.

OBJECTIVE: Acute pulmonary edema is a rare complication in women with preeclampsia especially at advanced maternal age. We aimed to determine the cardiovascular hemodynamics in advanced maternal age women who developed acute pulmonary edema and preeclampsia. STUDY DESIGN: Retrospective cohort study of women aged over 45 years giving birth at single university affiliated tertiary medical center which developed acute pulmonary edema due to severe preeclampsia. Clinical features were identified in order to predict and potentially prevent this severe complication of pregnancy. MAIN OUTCOME MEASURES: Advanced maternal age women who developed acute pulmonary edema due to preeclampsia. RESULTS: Overall, during the study period 90,540 women delivered in our hospital, of them, 540 women (0.6%) above the age of 45 years gave birth. Of those, 67 women (12.4%) had preeclampsia in which 4 women (6%) were complicated with acute pulmonary edema. The common clinical relevant characteristics for all four women were: preterm delivery by cesarean section for preeclampsia with severe features, non-restrictive fluid management around the time of delivery, post-partum pain control medication with non-steroidal anti-inflammatory drug, blood pressure stabilization with oral labetalol and a sudden hemodynamic deterioration to hypertensive crisis and pulmonary edema between post-operative days 4-9. CONCLUSION: Although the precise trigger for the sudden presentation of acute pulmonary edema remains unknown, we suggest that there is a multi-factorial combination of etiologies that are common to women of advanced maternal age and women with preeclampsia that could have contributed to the development of pulmonary edema.

In primary biliary cirrhosis (PBC) serum markers other than anti-mitochondrial antibodies (AMA) are promising in terms of disease severity and comorbidities, as well represented by anti-nuclear antibodies (ANA). The aim of the present study was thus to evaluate the prevalence and clinical significance of a large profile of serum autoantibodies in PBC sera. We utilized 69 sera from European patients with PBC (including 20 AMA-negative) and 297 sera from geographically and sex-matched healthy controls. All sera were tested for the presence of ANA and autoantibodies associated with thrombophilia, vasculitis, and gastrointestinal disease. Autoantibodies other than AMA were detected in 53/69 (76%) PBC sera vs. 105/297 (35%) among controls. The prevalence of ANA (targeting dsDNA, Sm, chromatin, ribosomal-P, RNP, SmRNP, SSA, SSB, and centromere) and thrombophilia-associated autoantibodies (i.e. anti-beta2GPI, phosphatydilserine, prothrombin) was common among patients with PBC. When clinical features were compared, the presence of anti-prothrombin IgM was associated with a worse prognosis as represented by a higher Mayo score. We demonstrate an increased prevalence of ANA and thrombophilia-associated autoantibodies in PBC sera and an association between the latter autoantibodies and PBC stage. The role of thrombophilia-associated antibodies will warrant further studies, based in particular on the incidence of portal hypertension at early stages of PBC.

OBJECTIVE: To evaluate the prevalence of serum antibodies against hepatitis C virus and other infectious agents in a large cohort of well-characterized patients with autoimmune diseases (AID). METHODS: We utilized 1322 sera from patients with 18 different AID and 236 sera from healthy controls from the same countries and with similar age and sex distribution. All sera were tested for the presence of serum anti-hepatitis C virus (HCV) antibodies as well as antibodies directed at other infectious agents and autoantibodies. RESULTS: Anti-HCV antibody was detected in 115/1322 (8.7%) of patients with AID and 0.4% of matched healthy controls (P < 0.0001). The prevalence of anti-HCV antibody was significantly higher in 7/18 different AID (i.e. cryoglobulinemia, mixed cryoglobulinemia pemphigus vulgaris, vasculitis, secondary anti-phospholipid syndrome, Hashimoto's thyroiditis, and inflammatory bowel disease) compared to controls. Patients with AID and serum anti-HCV positivity had an increased prevalence of antibodies against hepatitis B virus, Toxoplasma gondii and Cytomegalovirus as opposed to a lower frequency of serum autoantibodies. CONCLUSIONS: The enhanced prevalence of anti-HCV serum antibodies in AID may suggest a role for HCV in tolerance to breakdown, similarly to its established role in mixed cryoglobulinemia. This immune mediated effect does not rule out the role of other infectious agents.

OBJECTIVE: To determine optimum timing of external cephalic version (ECV). METHODS: A retrospective cohort study was conducted at a tertiary hospital in Israel between February 1, 2016, and July 1, 2017. Healthy primiparous women with breech presentation were offered either early ECV (35-36 weeks; n=54) or late ECV (37-38 weeks; n=106). Group assignment was according to the patient's preference and physician availability. The primary outcome was the rate of cephalic presentation at delivery. Secondary outcomes included rate of cesarean delivery, presentation of fetus after the first and last ECVs, and serious fetal complications. RESULTS: The incidence of undergoing more than two ECV attempts was 18.5% in the early ECV group and 5.6% in the late ECV group (P=0.039). The incidence of cephalic presentation after the first ECV was 72.2% in the early ECV group versus 66.0% in the late ECV group (P=0.048). By contrast, no statistically significant between-group differences were found for presentation at delivery or rate of cesarean delivery. The other outcomes were also similar. CONCLUSION: Early initiation of ECV among primiparous women increased the chance of immediate cephalic presentation; however, it had no effect on presentation at delivery or cesarean delivery rate.

BACKGROUND: Glycogen storage disease type I (GSDI) is caused by deficiency of the enzyme glucose-6-phosphatase or glucose-6-phosphate transporter. Mainstay of treatment is provision of uncooked cornstarch (and/or continuous nocturnal pump feed (CNPF) to maintain normoglycemia). Waxy maize heat modified starch (WMHMS) is another treatment option to maintain normoglycemia overnight. Our objective was to describe our experience treating children 2-5â¯years of age with GSDI using WMHMS overnight. METHOD: This is a retrospective case series review (nâ¯=â¯5) comparing the overnight feeding regimen and biochemical control one year before and after nocturnal WMHMS therapy. The WMHMS trial, in which blood glucose and lactate levels were monitored hourly, is reported in detail. RESULTS: Most patients successfully transitioned to nocturnal WMHMS feeds. These patients had stable glucose and lactate throughout the overnight period, permitting a fasting period of 6.5-8â¯h overnight. Within the time period studied, WMHMS appeared to have improved overnight control of blood glucose levels with fewer reported episodes of hypoglycemia compared to CNPF. CONCLUSION: WMHMS can be an effective substitute treatment to achieve stable nocturnal glucose control in children younger than five years of age. A larger multicenter prospective study is recommended to establish stronger evidence of the efficacy and safety of using WMHMS in treatment of young children with GSDI.
