BACKGROUND AND AIMS OF THE STUDY: Congenital syphilis is a rare complication of syphilis in pregnant women. Vertical transmission may occur at any time during pregnancy. The incidence of congenital syphilis has been increasing worldwide. Congenital syphilis has been a notifiable disease for many years in Switzerland but reporting does not include maternal features associated with syphilis in pregnancy or infantʼs subsequent development. We described syphilis cases among pregnant women screened over a 10-year period in Switzerland and subsequent cases of congenital syphilis, in order to identify maternal risk profiles and to optimise prevention. Second, we compared the characteristics of pregnant women screened early (1st trimester) vs late in pregnancy (2nd or 3rd trimester). Finally, we assessed the risk factors for premature birth among these women with syphilis. METHODS: A multicentre retrospective study conducted in Swiss hospitals from 2012 to 2021, including pregnant women who screened positive for syphilis (Treponema pallidum haemagglutination assay [TPHA] / T. pallidum particle agglutination assay [TPPA ] ≥1:80) and newborns exposed to T. pallidum in utero and/or congenitally infected and with a positive syphilis serology at birth. Data were collected from medical records. RESULTS: A total of 147 syphilis-positive pregnant women and 102 infants were included. A history of treated syphilis was known for 44% (65/147) of the mothers corresponding to a serological scar and the remaining 56% (82/147) were newly identified syphilis cases. Syphilis screening was done during the first trimester in 54%, second trimester in 29% and third trimester in 13% of cases. Two babies were diagnosed with congenital syphilis (1.96%). Several potential factors that could contribute to women’s risk of syphilis during pregnancy were identified such as a foreign origin (93% of mothers), lack of healthcare insurance (25%), no employment status (37%), drug use (5%), co-infection with other sexually transmitted infections (24%) and a late first antenatal consultation (42%). The number of pregnant women without insurance was higher in women diagnosed in the second or third trimester than in those diagnosed in the first trimester (odds ratio 0.41; 95% CI 0.19–0.89; p = 0.024). Syphilis diagnosed in the second or third trimester was associated with a late first antenatal consultation (odds ratio 77.82; 95% CI 9.81–617.21; p

Abstract Background The rates of maternal and neonatal deaths in Madagascar are among the highest in the world. In response to a request for additional training from obstetrical care providers at the Ambanja district hospital in north-eastern Madagascar, a partnership of institutions in Switzerland and Madagascar conducted innovative training on respectful emergency obstetric and newborn care using e-learning and simulation methodologies. The training focused on six topics: pre-eclampsia, physiological childbirth, obstetric maneuvers, postpartum hemorrhage, maternal sepsis, and newborn resuscitation. Cross-cutting themes were interprofessional communication and respectful patient care. Ten experienced trainers participated in an e-training-of-trainers course conducted by the Swiss partners. The newly-trained trainers and Swiss partners then jointly conducted the hybrid remote/in-person training for 11 obstetrical care providers in Ambanja. Methods A mixed methods evaluation was conducted of the impact of the training on participants’ knowledge and practices. Trainees’ knowledge was tested before, immediately after, and 6 months after the training. Focus group discussions were conducted to elicit participants’ opinions about the training, including the content and pedagogical methods. Results Trainees’ knowledge of the six topics was higher at 6 months (with an average of 71% correct answers) compared to before the training (62%), although it was even higher (83%) immediately after the training. During the focus group discussions, participants highlighted their positive impressions of the training, including its impact on their sense of professional effectiveness. They reported that their interprofessional relationships and focus on respectful care had improved. Simulation, which was a new methodology for the participants native to Madagascar, was appreciated for its engaging and active format, and they enjoyed the hybrid delivery of the training. Participants (including the trainers) expressed a desire for follow-up engagement, including additional training, and improved access to more equipment. Conclusion The evaluation showed improvements in trainees’ knowledge and capacity to provide respectful emergency care to pregnant women and newborns across all training topics. The hybrid simulation-based training method elicited strong enthusiasm. Significant opportunity exists to expand the use of hybrid onsite/remote simulation-based training to improve obstetrical care and health outcomes for women and newborns in Madagascar and elsewhere.

Abstract Background Lack of Cytomegalovirus (CMV) knowledge among healthcare professionals has been proven to be the main threat to pregnant women's awareness, preventing them from reducing the risk of infection. The aims of this study were to assess the knowledge and practices of French-speaking Swiss perinatal professionals in terms of CMV prevention, as well as the sociodemographic-professional factors that influence them. Methods This observational study used a cross-sectional design to collect data-via an anonymous electronic questionnaire in French distributed to gynecologists-obstetricians, general practitioners and midwives via various channels: e-mails and social networks of partner centers, professional associations, and conferences. The 41-item questionnaire collected data on sociodemographic and professional characteristics, general CMV knowledge, national recommendation knowledge and prevention practices. Univariable and multivariable analyses were performed. Results A total of 110 gynecologist-obstetricians, 5 general practitioners and 226 midwives participated in the study. While more than 80% of practitioners were familiar with protective hygiene measures, significant gaps were highlighted concerning the transmission routes, as well as the signs of short- and long-term congenital CMV infection. Regarding practice, 63.3% of participants provided information on CMV to their patients, mainly during the first antenatal visit. Among those who did not, lack of knowledge and forgetfulness were the two main reasons cited. Concerning systematic screening, 45.7% of participants offered it to their patients, and 37.3% only offered it to “at risk” groups. The existence of national guidelines on CMV was known by 62.0% of participants. Multivariable analysis revealed that working as a gynecologist-obstetrician was independently associated with higher score of preventive practices, while performing ultrasound or preconception consultations was independently associated with a higher score of general CMV knowledge, and working in a university hospital was independently associated with a higher score of Swiss recommendation knowledge. A level of training higher than the basic medical or midwifery diploma and participation in fetal medicine symposia both promote a higher score of CMV knowledge and prevention practices in line with current recommendations. Conclusion This study confirms the significant gaps in CMV knowledge among French-speaking Swiss caregivers along with the heterogeneity of their prevention practices. To raise awareness among pregnant women and reduce the burden of congenital CMV infections, improving professional knowledge through access to specific training and standardizing practices should be a national priority.

Summary: Background: Low rates of postnatal retention in HIV care and viral suppression have been reported in women living with HIV (WLWH) despite viral suppression at delivery. At the same time, postpartum follow-up is of crucial importance in light of the increasing support offered in many resource-rich countries including Switzerland to WLWH choosing to breastfeed their infant, if optimal scenario criteria are met. Methods: We longitudinally investigated retention in HIV care, viral suppression, and infant follow-up in a prospective multicentre HIV cohort study of WLWH in the optimal scenario who had a live birth between January 2000 and December 2018. Risk factors for adverse outcomes in the first year postpartum were assessed using logistic and proportional hazard models. Findings: Overall, WLWH were retained in HIV care for at least six months after 94.2% of the deliveries (694/737). Late start of combination antiretroviral therapy (cART) during the third trimester was found to be the main risk factor for failure of retention in HIV care (crude odds ratio [OR] 3.91; 95% confidence interval [CI], 1.50–10.22; p = 0.005). Among mothers on cART until at least one year after delivery, 4.4% (26/591) experienced viral failure, with illicit drugs use being the most important risk factor (hazard ratio [HR], 13.2; 95% CI, 2.35–73.6; p = 0.003). The main risk factors for not following the recommendations regarding infant follow-up was maternal depression (OR, 3.52; 95% CI, 1.18–10.52; p = 0.024). Interpretation: Although the results are reassuring, several modifiable risk factors for adverse postpartum outcome, such as late treatment initiation and depression, were identified. These factors should be addressed in HIV care of all WLWH, especially those opting to breastfeed in resource-rich countries. Funding: This study has been financed within the framework of the Swiss HIV Cohort Study, supported by the Swiss National Science Foundation (grant #201369), by SHCS project 850 and by the SHCS research foundation.

Sneathia sanguinegens, Sneathia vaginalis, and Mageeibacillus indolicus have been recently described in the female genital tract. We present the first case of a postpartum septic arthritis of the pubic symphysis due to these organisms, identified by next generation sequencing.

Objective: The caesarean section (CS) rate in Switzerland is currently 32 %, well above the WHO recommended rate of 15 %. The study aims were three-fold: to explore the perception of this high rate among Swiss obstetrics‐gynecology (Ob-Gyn) professionals; to assess the factors associated with a perception of a too high national CS rate; and to describe professionals’ opinions on measures to reduce this rate. Study design: A cross-sectional study was conducted between 1 May and 30 June 2021 using an online questionnaire sent to Ob/Gyn physicians and midwives at a university hospital and members of the Swiss Conference of Heads of Ob/Gyn Divisions. Survey participation was voluntary. The main outcome was the belief that CS was high. Associations were explored between different factors and the main outcome with logistic regression. Results were presented as odds ratios (OR) with 95 % confidence intervals (CIs). Multivariate logistic regression included adjustments for age, gender, place of work and profession. Results: Of 226 health professionals invited, 188 completed the questionnaire (83.2 % participation rate). Among respondents, 50.3 % (n = 94) were Ob/Gyn physicians and 49.7 % were midwives (n = 93); 77.1 % were women (n = 145). Most participants (74.7 % [n = 139]) considered the Swiss CS rate as too high and that it should be reduced (79 % [n = 147]) but, notably, they considered their own CS rate as correct (71.9 % [n = 123]). Improving patient education (57.5 % [n = 108]) and professional training (54.8 % [n = 103]) were considered as strategies to reduce this rate. In multivariate analysis, only length of professional experience was significantly associated with a higher likelihood of considering the CS rate as too high (OR 3.07, 95 % CI 1.01–9.30; p = 0.047). When specialty was added in the model, the length of professional experience disappeared and the perception of having a too high CS rate was associated with being a midwife and obstetrician rather than a gynecologist (OR 3.62, 95 % CI 1.72–7.63; p = 0.001). Conclusions: Clinicians, particularly obstetricians, believed that the current rate of CS in Switzerland was too high and that actions were needed to reduce this rate. Improving patient education and professional training were considered as the main strategies to be explored.

Inspired by the six quality-of-care goals developed by the Institute of Medicine, woman-centred care (WCC) as model of care is used in maternity services as it gives an emphasis on the woman as an individual and not her status as a patient. Bringing stronger attention to women's needs and values, is proven to have clear benefits for perinatal outcomes, but fails to be known or recognised by healthcare professionals' (HCPs) and implemented. Using a mixed-methods approach, this study aimed to explore HCPs definitions of WCC and identify the degree of agreement and knowledge regarding perinatal indicators when a WCC model of care is implemented. The quantitative part was carried using a self-administered questionnaire with perinatal indicators identified from the literature. Semi-structured interviews were realized using a purposive sample of 15 HCPs and an interview grid inspired by Leap's WCC model. The study was conducted in the maternity of a university hospital in French-speaking part of Switzerland. Out of 318 HCPs working with mothers and their newborns, 51% had already heard of WCC without being familiar with Leap's model. The HCPs were aware of the positive perinatal care outcomes when WCC was implemented: women's satisfaction (99.2%), health promotion (97.6%), HCP's job satisfaction (93.2%) and positive feelings about their work (85.6%), which were strongly emphasised in the interviews. The respondents reported institutional difficulties in implementing the model such as administrative overload and lack of time. The positive outcomes of WCC on spontaneous deliveries and improved neonatal adaptation were known by most HCPs (63.4% and 59.9%, respectively). However, fewer than half of the HCPs highlighted the model's positive effects on analgesia and episiotomies or its financial benefits. Knowledge of quality-of-care outcomes (i.e women's satisfaction, positive impact on practice…) was prevalent among most of HCPs. Without adhering to a common definition and without a specific model for consensus, most providers have integrated some aspects of WCC into their practice. However, specific perinatal indicators remain largely unknown, which may hinder the implementation of WCC.

Abstract Pregnant women may be at higher risk of severe complications associated with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which may lead to obstetrical complications. We performed a case control study comparing pregnant women with severe coronavirus disease 19 (cases) to pregnant women with a milder form (controls) enrolled in the COVI-Preg international registry cohort between March 24 and July 26, 2020. Risk factors for severity, obstetrical and immediate neonatal outcomes were assessed. A total of 926 pregnant women with a positive test for SARS-CoV-2 were included, among which 92 (9.9%) presented with severe COVID-19 disease. Risk factors for severe maternal outcomes were pulmonary comorbidities [aOR 4.3, 95% CI 1.9–9.5], hypertensive disorders [aOR 2.7, 95% CI 1.0–7.0] and diabetes [aOR2.2, 95% CI 1.1–4.5]. Pregnant women with severe maternal outcomes were at higher risk of caesarean section [70.7% (n = 53/75)], preterm delivery [62.7% (n = 32/51)] and newborns requiring admission to the neonatal intensive care unit [41.3% (n = 31/75)]. In this study, several risk factors for developing severe complications of SARS-CoV-2 infection among pregnant women were identified including pulmonary comorbidities, hypertensive disorders and diabetes. Obstetrical and neonatal outcomes appear to be influenced by the severity of maternal disease.

Summary: Background: Pregnant individuals with coronavirus disease 2019 (COVID-19) are at increased risk of severe disease, prematurity, and stillbirth. In March 2021, vaccination for at risk pregnant women was recommended in Switzerland, expanding this to all pregnant women in May 2021. Our aim was to assess the safety of mRNA COVID-19 vaccines in pregnancy. Methods: This multicentre prospective cohort study describes early adverse events and perinatal outcomes in pregnant women who received at least one dose of mRNA vaccine between March 1st and December 27th, 2021 in Switzerland, using the COVI-PREG registry. Early adverse events were collected at least one month following vaccine administration. Pregnancy and neonatal outcomes were extracted from medical records using the maternity discharge letters providing follow-up information up to 5 days after birth. Findings: Of 1012 vaccinated women, 894 (88·3%) received both injections during pregnancy, with BNT162b2 (n = 271) or mRNA-1273 (n = 623) vaccines. Local events (mainly local pain) were reported in 81·3% and 80·5% after the first and second doses. Rates of systemic reactions (mainly fatigue and headache) were similar after the first dose and most frequent after the second dose of mRNA-1273. Of the 1012 women, four (0·4%; 95%CI [0·1-1·0]) severe early adverse events occurred: pulmonary embolism, preterm premature rupture of membranes, isolated fever with hospitalisation, and herpes zoster. Of 107 patients vaccinated before 14 weeks, one (0·9%; 95%CI [0·0-5·1]) early spontaneous abortions was reported (8 weeks). Of 228 vaccinated before 20 weeks one (0·4%; 95%CI [0·0-2·4]) late spontaneous abortion was reported (16 weeks). Of 513 women exposed before 37 weeks, 33 (6·4%; 95%CI [4·5-8·9]) delivered preterm. Among 530 patients exposed in pregnancy, no stillbirth was reported and 25 (4·7%; 95%CI [3·0-6·8]) neonates were admitted to intensive care unit. Interpretation: Frequent local and systemic effects were described after exposure to mRNA COVID-19 vaccines during pregnancy but severe events were rare. Women vaccinated during pregnancy did not experience higher adverse pregnancy or neonatal outcomes when compared to historical data on background risks in the obstetric population. Funding: This research was funded by a grant from the Swiss Federal Office of Public Health and the CHUV Foundation.

Abstract Background Preeclampsia is a major pregnancy complication that results in significant maternal and infant mortality, most of which occurs in low and middle-income countries. The accurate and timely diagnosis of preeclampsia is critical in management of affected pregnancies to reduce maternal and fetal/neonatal morbidity and mortality, yet difficulties remain in establishing the rigorous diagnosis of preeclampsia based on clinical parameters alone. Biomarkers that detect biochemical disease have been proposed as complements or alternatives to clinical criteria to improve diagnostic accuracy. This cohort study assessed the performance of several biomarkers, including glycosylated fibronectin (GlyFn), to rule-in or rule-out preeclampsia within 4 weeks in a cohort of women at increased risk for preeclampsia. Methods 151 women with risk factors for or clinical signs and symptoms of preeclampsia were selected from a prospective cohort. Maternal serum samples were collected between 20 and 37 weeks of gestation. Clinical suspicion of preeclampsia was defined as presence of new-onset proteinuria, or clinical symptoms of preeclampsia. Subjects with a clinical diagnosis of preeclampsia at the time of enrollment were excluded. GlyFn, pregnancy-associated plasma protein-A2 (PAPPA2), placental growth factor (PlGF), and soluble fms-like tyrosine kinase-1 (sFlt-1) were measured by immunoassay. GlyFn was also determined using a rapid point-of care (POC) test format. Receiver-operating characteristic (ROC) curves derived from logistic regression analysis were used to determine the classification performance for each analyte. Results 32 of 151 (21%) women developed a clinical diagnosis of preeclampsia within 4 weeks. All biomarkers exhibited good classification performance [GlyFn (area under the curve (AUROC) = 0.94, 91% sensitivity, 86% specificity); PAPPA2 AUC = 0.92, 87% sensitivity, 77% specificity; PlGF AUC = 0.90, 81% sensitivity, 83% specificity; sFlt-1 AUC = 0.92, 84% sensitivity, 91% specificity. The GlyFn immunoassay and the rapid POC test showed a correlation of r = 0.966. Conclusions In this prospective cohort, serum biomarkers of biochemical disease were effective in short-term prediction of preeclampsia, and the performance of GlyFn in particular as a POC test may meet the needs of rapid and accurate triage and intervention.

BackgroundRecent studies have shown that elective induction of labor versus expectant management after 39 weeks of pregnancy result in lower incidence of perinatal complications, while the proportion of cesarean deliveries remains stable, or even decreases. Still, evidence regarding collateral consequences of the potential increase of induction of labor procedures is still lacking. Also, the results of these studies must be carefully interpreted and thoroughly counter-balanced with women's thoughts and opinions regarding the active management of the last weeks of pregnancy. Therefore, it may be useful to develop a tool that aids in the decision-making process by differentiating women who will spontaneously go into labor from those who will require induction.ObjectiveTo develop a predictive model to calculate the probability of spontaneous onset of labor at term.MethodsWe designed a prospective national multicentric observational study including women enrolled at 39 weeks of gestation, carrying singleton pregnancies. After signing an informed consent form, several clinical, ultrasonographic, biophysical and biochemical variables will be collected by trained staff. If delivery has not occurred at 40 weeks of pregnancy, a second visit and evaluation will be performed. Prenatal care will be continued according to current hospital guidelines. Once recruitment is completed, the information gathered will be used to develop a logistic regression-based predictive model of spontaneous onset of labor between 39 and 41 weeks of gestation. A secondary exploration of the data collected at 40 weeks, as well as a survival analysis regarding time-to-delivery outcomes will also be performed. A total sample of 429 participants is needed for the expected number of events.ConclusionThis study aims to develop a model which may help in the decision-making process during follow-up of the last weeks of pregnancy.Trial registrationNCT05109247 (clinicaltrials.gov).

Abstract Background Autosomal recessive renal polycystic kidney disease occurs in 1 in 20,000 live births. It is caused by mutations in both alleles of the PKHD1 gene. Management of delivery in cases of suspected autosomal recessive renal polycystic kidney disease is rarely discussed, and literature concerning abdominal dystocia is extremely scarce. We present a case of a patient with autosomal recessive renal polycystic kidney disease whose delivery was complicated by abdominal dystocia, and we discuss the factors that determined the route and timing of delivery. Case presentation A 23-year-old Caucasian woman, G2 P0, with a prior unremarkable pregnancy was referred to our tertiary center at 31 weeks of gestation because of severe oligoamnios (amniotic fluid index = 2) and hyperechogenic, dedifferentiated, and enlarged fetal kidneys. She had no other genitourinary anomaly. Fetal magnetic resonance imaging showed enlarged, hypersignal kidneys and severe pulmonary hypoplasia. We had a high suspicion of autosomal recessive renal polycystic kidney disease, and after discussion with our multidisciplinary team, the parents opted for conservative care. Ultrasound performed at 35 weeks of gestation showed a fetal estimated weight of 3550 g and an abdominal circumference of 377 mm, both above the 90th percentile. Because of the very rapid kidney growth and suspected risk of abdominal dystocia, we proposed induction of labor at 36 weeks of gestation after corticosteroid administration for fetal lung maturation. Vaginal delivery was complicated by abdominal dystocia, which resolved by continuing expulsive efforts and gentle fetal traction. A 3300-g (P50–90) male infant was born with Apgar scores of 1-7-7 at 1, 5, and 10 minutes, respectively, and arterial and venous umbilical cord pH values of 7.23–7.33. Continuous peritoneal dialysis was started at day 2 of life because of anuria. Currently, the infant is 1 year old and is waiting for kidney transplant that should be performed once he reaches 10 kg. Molecular analysis of PKHD1 performed on deoxyribonucleic acid (DNA) from the umbilical cord confirmed autosomal recessive renal polycystic kidney disease. Conclusions Management of delivery in cases of suspected autosomal recessive renal polycystic kidney disease needs to be discussed because of the risk of abdominal dystocia. The route and timing of delivery depend on the size of the fetal abdominal circumference and the gestational age. The rate of kidney growth must also be taken into account.

Abstract Background Late preterm (LPT) newborns, defined as those born between 34 0/7 and 36 6/7 gestational weeks, have higher short- and long-term morbidity and mortality than term infants (≥37 weeks). A categorization to justify a non-spontaneous LPT delivery has been proposed to distinguish evidence-based from non-evidence-based criteria. This study aims to describe rates and temporal trends of non-spontaneous LPT neonates delivered according to evidence-based or non-evidence-based criteria and to evaluate the number of avoidable LPT deliveries, including severe neonatal morbidity rates and associated risk factors. Methods Retrospective cohort study including all LPT neonates born at a Swiss university maternity unit between January 1, 2002 and December 31, 2012. Trends of LPT neonates and neonatal complications were assessed across time using Poisson regression and risk factors for neonatal complications by logistic regression. Results Among 40,609 singleton live births, 4223 (10.5%) were preterm and 2017 (4.9%) LPT. In the latter group, 26.2% were non-spontaneous (evidence-based: 12.0%; non-evidence-based: 14.2%). The most frequent indications for evidence-based non-spontaneous LPT delivery were severe preeclampsia (51.8%) and abnormal fetal tracing (24.7%). Indications for non-evidence-based non-spontaneous LPT deliveries were hemorrhage (36.2%) and mild preeclampsia (15.7%). LPT birth rates remained stable over time. The rate of neonatal complications after non-evidence-based LPT birth remained high over time (43.8% vs. 43.5% in 2002 and 2012, respectively; P = 0.645), whereas the annual proportion of neonatal complications overall showed a decreasing trend (from 38.0% in 2002 to 33.5% in 2012; P = 0.051). Conclusions LPT birth rates were stable over time, but neonatal complications remained high, particularly after non-evidence-indicated LPT birth. A total of 287 LPT births could have been potentially avoided if an evidence-based protocol for delivery indications had been used. Efforts should be made to avoid non-spontaneous LPT births in order to reduce neonatal complications.

Placental development and function implicate important morphological and physiological adaptations to thereby ensure efficient maternal–fetal exchanges, as well as pregnancy-specific hormone secretion and immune modulation. Incorrect placental development can lead to severe pregnancy disorders, such as preeclampsia (PE), which endangers both the mother and the infant. The implication of the systemic renin–angiotensin system (RAS) in the pregnancy-related physiological changes is now well established. However, despite the fact that the local uteroplacental RAS has been described for several decades, its role in placental development and function seems to have been underestimated. In this review, we provide an overview of the multiple roles of the uteroplacental RAS in several cellular processes of placental development, its implication in the regulation of placental function during pregnancy, and the consequences of its dysregulation in PE pathogenesis.

Abstract Background Preterm birth is in quantity and in severity the most important contributor of perinatal morbidity and mortality both in well- and low-resource countries. Cervical pessary and cervical cerclage are both considered as preventive treatments in women at risk for preterm birth. We aim to evaluate whether a cervical pessary can replace cervical cerclage for preventing recurrent preterm birth in women with a prior preterm birth due to cervical insufficiency or in women with a prior preterm birth and a short cervix in the current pregnancy. Methods/design A nationwide open-label multicentre randomised clinical trial will be set up to study women with a singleton pregnancy and a prior preterm birth before 34 weeks of gestation. Women are eligible in case of previous preterm birth based on cervical insufficiency (primary intervention,

In this multicentre cohort study, we evaluated the risks of maternal ZIKV infections and adverse pregnancy outcomes among exposed travellers compared to women living in areas with ZIKV circulation (residents). The risk of maternal infection was lower among travellers compared to residents: 25.0% (n = 36/144) versus 42.9% (n = 309/721); aRR 0.6; 95% CI 0.5–0.8. Risk factors associated with maternal infection among travellers were travelling during the epidemic period (i.e., June 2015 to December 2016) (aOR 29.4; 95% CI 3.7–228.1), travelling to the Caribbean Islands (aOR 3.2; 95% CI 1.2–8.7) and stay duration >2 weeks (aOR 8.7; 95% CI 1.1–71.5). Adverse pregnancy outcomes were observed in 8.3% (n = 3/36) of infected travellers and 12.7% (n = 39/309) of infected residents. Overall, the risk of maternal infections is lower among travellers compared to residents and related to the presence of ongoing outbreaks and stay duration, with stays

Background: Maternal obesity, excessive gestational weight gain (GWG) and post-partum weight retention (PPWR) constitute new public health challenges, due to the association with negative short- and long-term maternal and neonatal outcomes. The aim of this evidence review was to identify effective lifestyle interventions to manage weight and improve maternal and infant outcomes during pregnancy and postpartum.Methods: A review of systematic reviews and meta-analyses investigating the effects of lifestyle interventions on GWG or PPWR was conducted (Jan 2009–2018) via electronic searches in the databases Medline, Pubmed, Web of Science and Cochrane Library using all keywords related to obesity/weight gain/loss, pregnancy or postpartum and lifestyle interventions;15 relevant reviews were selected.Results: In healthy women from all BMI classes, diet and physical activity interventions can decrease: GWG (mean difference −1.8 to −0.7 kg, high to moderate-quality evidence); the risks of GWG above the IOM guidelines (risk ratio [RR] 0.72 to 0.80, high to low-quality evidence); pregnancy-induced hypertension (RR 0.30 to 0.66, low to very low-quality evidence); cesarean section (RR 0.91 to 0.95; high to moderate-quality evidence) and neonatal respiratory distress syndrome (RR 0.56, high-quality evidence); without any maternal/fetal/neonatal adverse effects. In women with overweight/obesity, multi-component interventions can decrease: GWG (−0.91 to −0.63 kg, moderate to very low-quality evidence); pregnancy-induced hypertension (RR 0.30 to 0.66, low-quality evidence); macrosomia (RR 0.85, 0.73 to 1.0, moderate-quality evidence) and neonatal respiratory distress syndrome (RR 0.47, 0.26 to 0.85, moderate-quality evidence). Diet is associated with greater reduction of the risks of GDM, pregnancy-induced hypertension and preterm birth, compared with any other intervention. After delivery, combined diet and physical activity interventions reduce PPWR in women of any BMI (−2.57 to −2.3 kg, very low quality evidence) or with overweight/obesity (−3.6 to −1.22, moderate to very low-quality-evidence), but no other effects were reported.Conclusions: Multi-component approaches including a balanced diet with low glycaemic load and light to moderate intensity physical activity, 30–60 min per day 3–5 days per week, should be recommended from the first trimester of pregnancy and maintained during the postpartum period. This evidence review should help inform recommendations for health care professionals and women of child-bearing age.

Combined antiretroviral treatment (cART) has reduced mother-to-child transmission (MTCT) of the human immunodeficiency virus (HIV) to virtually zero in industrialised countries, where strictly bottle feeding is recommended for HIV-infected mothers, and to as low as 0.7% after 12 months in low-resource settings, where breastfeeding is strongly encouraged. Given the theoretically very low risk of transmission by breastfeeding with cART, and the advantages and benefits of breastfeeding, also in industrialised countries, the strong recommendation to HIV-infected mothers to refrain from breastfeeding in this setting may no longer be justified. We have evaluated risks of breastfeeding for HIV MTCT in the light of accessible cART, the general benefits of breastfeeding, and the women's autonomy to consent to any intervention. As we found no evidence in the literature of HIV MTCT via breastfeeding whilst on effective cART, we identified a situation of clinical equipoise. We propose how to proceed in Switzerland when HIV-infected women consider breastfeeding. We advocate a shared decision-making process and suggest a list of topics on which to provide unbiased information for the HIV-infected mother to enable her comprehensive understanding of one or the other decision. Although breastfeeding still should not be actively recommended in Switzerland, any HIV-infected mother, regardless of her geographical and cultural background, who decides to breastfeed should be supported by the best strategy to achieve optimal medical care for both herself and her child. This includes continuous support of cART adherence and regular maternal HIV plasma viral load monitoring.

Treponema pallidum PCR (Tp-PCR) has been noted as a valid method for diagnosing syphilis. We compared Tp-PCR to a combination of darkfield microscopy (DFM), the reference method, and serologic testing in a cohort of 273 patients from France and Switzerland and found the diagnostic accuracy of Tp-PCR was higher than that for DFM.

STUDY/PRINCIPLES: Antibiotic prophylaxis of Group B Streptococcus (GBS) positive women during labour reduces the risk of early-onset neonatal sepsis. Penicillin is the first choice, and clindamycin and erythromycin are second choices for penicillin-allergic women. Resistance to these antibiotics is rising. The aims of this study were to evaluate the rates of clindamycin and erythromycin resistance among GBS-positive isolates cultures from pregnant women in the University Hospital of Geneva and to evaluate the legitimacy of new Centres for Disease Control and Prevention (CDC) recommendations for our context. METHODS: We collected a vagino-rectal swab from pregnant women at 35–37 weeks gestation. We recovered 124 GBS positive isolates. Identification was based on the characteristic of the colony on the chromogenic agar, the streptococcal agglutination test and confirmation by mass spectrometry. Antimicrobial susceptibility was determined by disk diffusion, according to CLSI guidelines 2010. RESULTS: The rate of resistance to clindamycin was 28% and to erythromycin was 30%. Only 3 of the 38 erythromycin resistant strains (7.9%) were susceptible to clindamycin, and only 3 out of the 35 clindamycin resistant GBS (8.6%) were identified as “inducible resistance”. The rate of co-resistance to clindamycin of erythromycin-resistant strains was 92%. Penicillin remained efficacious in all cases. CONCLUSION: Rates of clindamycin and erythromycin resistance are also increasing in our context. These antibiotics should not be used for GBS neonatal sepsis prevention, without adequate antimicrobial susceptibility testing. In case of penicillin allergy and lack of antibiogramm, cephalosporins or vancomycin should be used as recommended in CDC guidelines.

Purpose Prospective, multicentric observational cohort study in Switzerland investigating measures to prevent mother-to-child transmission in pregnant women with HIV (WWH) and assessing health and development of their exposed children as well as of children with HIV (CWH) in general.Participants Between January 1986 and December 2022, a total of 1446 mother–child pairs were enrolled. During the same period, the study also registered 187 CWH and 521 HIV-exposed but uninfected children (HEU), for whom detailed maternal information was not available. Consequently, the cohort comprises a total of 2154 children.Findings to date During these 37 years, research by the Swiss Mother and Child HIV Cohort Study (MoCHiV) and its international collaborators has strongly influenced the prevention of vertical transmission of HIV (eg, introduction and discontinuation of elective caesarean section, neonatal postexposure prophylaxis and breastfeeding). Contributions have also been made to the management of diagnostics (eg, p24 antigen assay) and the effects of antiretroviral treatment (eg, prematurity, growth) in HEU and CWH.Future plans Most children present within the cohort are now HEU, highlighting the need to investigate other vertically transmitted pathogens such as hepatitis B and C viruses, cytomegalovirus or Treponema pallidum. In addition, analyses are planned on the longitudinal health status of CWH (eg, resistance and prolonged exposure to antiretroviral therapy), on social aspects including stigma in CWH and HEU, and on interventions to further optimise antenatal and postpartum care in WWH.
