Objectives: We aimed to assess the effects of risk-based travel restrictions on (1) international travel frequency, (2) SARS-CoV-2 case importation risk, (3) national SARS-CoV-2 incidence and (4) importation of SARS-CoV-2 variants into Scotland.

Design: Population-based surveillance study.

Setting: The study utilises SARS-CoV-2 community testing from February 2021 to May 2022 in Scotland, UK and spans the introduction of the UK's 'traffic light system' policy in May 2021.

Global inequities in adverse pregnancy outcomes: what can we do?

The Health Equity Leadership & Exchange Network states that "health equity exists when all people, regardless of race, sex, sexual orientation, disability, socioeconomic status, geographic location, or other societal constructs, have fair and just access, opportunity, and resources to achieve their highest potential for health." It is clear from the wide discrepancies in maternal and infant mortalities, by race, ethnicity, location, and social and economic status, that health equity has not been achieved in pregnancy care. Although the most obvious evidence of inequities is in low-resource settings, inequities also exist in high-resource settings.

Development and validation of a prognostic model to predict birth weight: individual participant data meta-analysis.

Objective: To predict birth weight at various potential gestational ages of delivery based on data routinely available at the first antenatal visit.

Design: Individual participant data meta-analysis.

Data Sources: Individual participant data of four cohorts (237 228 pregnancies) from the International Prediction of Pregnancy Complications (IPPIC) network dataset.

Small RNAs in the pathogenesis of preeclampsia.

Preeclampsia is a major contributor to maternal and fetal morbidity and mortality. The disorder can be classified into early- and late-onset subtypes, both of which evolve in two stages. The first stage comprises the development of pre-clinical, utero-placental malperfusion.

Implementation and Outcomes of an Academic Peer Coaching Program for Pediatric Residents.

Introduction Academic coaching fosters self-directed learning and is growing in popularity within residency programs. Implementation is often limited by available faculty time and funding. Peer coaching is an emerging alternative but is not well studied.

Graduate medical education success coaching for residents and fellows: a single-institution real-world experience.

While coaching has been employed as a success strategy in many areas such as athletics and business for decades, its use is relatively new in the medical field despite evidence of its benefits. Implementation and engagement regarding coaching in graduate medical education (GME) for residents and fellows is particularly scarce. We report our three-year experience of a GME success coaching program that aims to help trainees reach their full potential by addressing various areas of medical knowledge, clinical skills, efficiency, interpersonal skills and communication, professionalism, and mental health and well-being.

A method to isolate syncytiotrophoblast-derived medium-large extracellular vesicle small RNA from maternal plasma.

Syncytiotrophoblast-derived extracellular vesicles (STB-EVs) have an important role in placental research: both as mediators of feto-maternal signalling and as liquid biopsies reflecting placental health. Recent evidence highlights the importance of STB-EV RNA. Isolation of STB-EV RNA from maternal blood is therefore an important challenge.

A mixed-methods landscape assessment of supportive care for heart failure.

Understanding factors that shape leading health systems' (LHS) perspectives around heart failure (HF) treatment. First of its kind study using a cross-sectional, descriptive, mixed-method design (from executives and frontline healthcare providers) with quantitative survey (n = 35) and qualitative interview (n = 12) data from 47 participants (41 different LHS). 97% of LHS had dedicated HF programs, but variations in maturity highlights opportunities for care standardization.

Differential 5'-tRNA Fragment Expression in Circulating Preeclampsia Syncytiotrophoblast Vesicles Drives Macrophage Inflammation.

Background: The relationship between placental pathology and the maternal syndrome of preeclampsia is incompletely characterized. Mismatch between placental nutrient supply and fetal demands induces stress in the syncytiotrophoblast, the layer of placenta in direct contact with maternal blood. Such stress alters the content and increases the release of syncytiotrophoblast extracellular vesicles (STB-EVs) into the maternal circulation.

Added value of electrical impedance spectroscopy in adjunction of colposcopy: a prospective cohort study.

Objective: To assess whether electrical impedance spectroscopy (EIS) as an adjunctive technology enhances the performance of colposcopy.

Design: Prospective cohort study.

Setting: University Hospital colposcopy clinic.

PREPARE: A Stepped-Wedge Cluster-Randomized Trial to Evaluate Whether Risk Stratification Can Reduce Preterm Deliveries Among Patients With Suspected or Confirmed Preterm Preeclampsia.

Background: Early delivery in preterm preeclampsia may reduce the risks for the patient, but consequences of prematurity may be substantial for the baby. This trial evaluated whether the implementation of a risk stratification model could safely reduce prematurity.

Methods: This was a stepped-wedge cluster-randomized trial in seven clusters.

ExoCounter Assays Identify Women Who May Develop Early-Onset Preeclampsia From 12.5 μL First-Trimester Serum by Characterizing Placental Small Extracellular Vesicles.

Background: Preeclampsia is a major cause of maternal and perinatal morbidity and mortality worldwide. Identifying women with high risk of developing preeclampsia in early pregnancy remains challenging. Extracellular vesicles released from the placenta offer an attractive biomarker but have been elusive to quantify.

Placental capillary pericytes release excess extracellular vesicles under hypoxic conditions inducing a pro-angiogenic profile in term pregnancy.

Pericytes are multifunctional cells wrapped around capillary endothelia, essential for vascular health, development, and blood flow regulation, although their role in human placental chorionic villi has not been fully explored. The second half of normal pregnancy is characterized by a progressive decline in placental and fetal oxygen levels which, by term, comprises a substantial degree of hypoxia. We hypothesized this hypoxia would stimulate pericyte regulation of chorionic villous capillary function.

Predelivery placenta-associated biomarkers and computerized intrapartum fetal heart rate patterns.

Background: Increasing syncytiotrophoblast stress in term and postdate placentas is reflected by increasing antiangiogenic dysregulation in the maternal circulation, with low "proangiogenic" placental growth factor concentrations and increased "antiangiogenic" soluble fms-like tyrosine kinase-1 concentrations. Imbalances in these placenta-associated proteins are associated with intrapartum fetal compromise and adverse pregnancy and delivery outcome. Cardiotocography is widely used to assess fetal well-being during labor, but it is insufficient on its own for predicting adverse neonatal outcome.

Preeclampsia and syncytiotrophoblast membrane extracellular vesicles (STB-EVs).

Preeclampsia (PE) is a hypertensive complication of pregnancy that affects 2-8% of women worldwide and is one of the leading causes of maternal deaths and premature birth. PE can occur early in pregnancy (<34 weeks gestation) or late in pregnancy (>34 weeks gestation). Whilst the placenta is clearly implicated in early onset PE (EOPE), late onset PE (LOPE) is less clear with some believing the disease is entirely maternal whilst others believe that there is an interplay between maternal systems and the placenta.

Use of mHealth tools to register birth outcomes in low-income and middle-income countries: a scoping review.

Objective: Accurate reporting of birth outcomes in low-income and middle-income countries (LMICs) is essential. Mobile health (mHealth) tools have been proposed as a replacement for conventional paper-based registers. mHealth could provide timely data for individual facilities and health departments, as well as capture deliveries outside facilities.

Observation and Patients' Perceptions of Incorporating Their Photograph Into the Electronic Health Record.

Objectives: Wrong-patient errors are common and have the potential to cause serious harm. The Office of the National Coordinator for Health Information Technology Patient Identification SAFER Guide recommends displaying patient photographs in electronic health record (EHR) systems to facilitate patient identification and reduce wrong-patient errors. A potential barrier to implementation is patient refusal; however, patients' perceptions about having their photograph captured during registration and integrated into the EHR are unknown.

HPV vaccination and cervical screening: the knowledge and attitudes of mothers of adolescent girls.

Objective: Mothers play a significant role in decision making about human papillomavirus (HPV) vaccination for their daughters and about cervical screening attendance for themselves. This study had three objectives, to explore: (1) mothers' knowledge and attitudes about HPV and HPV vaccination, (2) their knowledge and attitudes about cervical cancer and screening, and (3) whether their daughter's HPV vaccination invitation was an opportunity to nudge mothers to attend screening.

Design: 138 women from North Staffordshire completed a cross-sectional survey and 15 took part in follow-up focus groups.

The Impact of COVID-19 Pandemic on Screening Programs for Cervical Cancer Prevention Across Europe.

Objective: The aim of the study was to estimate the impact of COVID-19 pandemic on the practice of cervical cancer screening in European countries.

Materials And Methods: A 3 rounds e-survey was conducted among the 31 European Federation for Colposcopy member countries during 2020. Each representative was asked to answer to each questionnaire for their own country.

Evidence of alliesthesia during a neighborhood thermal walk in a hot and dry city.

Designing cities for thermal comfort is an important priority in a warming and urbanizing world. As temperatures in cities continue to break extreme heat records, it is necessary to develop and test new approaches capable of tracking human thermal sensations influenced by microclimate conditions, complex urban geometries, and individual characteristics in dynamic settings. Thermal walks are a promising novel research method to address this gap.

Syncytiotrophoblast-derived extracellular vesicles carry apolipoprotein-E and affect lipid synthesis of liver cells in vitro.

In normal pregnancy, hepatic metabolism adaptation occurs with an increase in lipid biosynthesis. Placental shedding of syncytiotrophoblast-derived extracellular vesicles (STBEVs) into the maternal circulation constitutes a major signalling mechanism between foetus and mother. We investigated whether STBEVs from normal pregnant women might target liver cells in vitro and induce changes in lipid synthesis.

The association between placenta-associated circulating biomarkers and composite adverse delivery outcome of a likely placental cause in healthy post-date pregnancies.

Introduction: Post-date pregnancies have an increased risk of adverse delivery outcome. Our aim was to explore the association between placenta-associated circulating biomarkers and composite adverse delivery outcome of a likely placental cause in clinically healthy post-date pregnancies.

Material And Methods: Women with healthy singleton post-date pregnancies between 40 and 42  weeks of gestation were recruited to this prospective, observational study conducted at Oslo University Hospital, Norway (NCT03100084).

Syncytiotrophoblast Extracellular Vesicles From Late-Onset Preeclampsia Placentae Suppress Pro-Inflammatory Immune Response in THP-1 Macrophages.

Syncytiotrophoblast derived Extracellular Vesicles (STBEV) from normal pregnancy (NP) have previously been shown to interact with circulating monocytes and B cells and induce pro-inflammatory cytokine release. Early-onset preeclampsia (EOPE) is associated with an exacerbated inflammatory response, yet there is little data regarding late-onset PE (LOPE) and immune function. Here, using a macrophage/monocyte cell line THP-1, we investigated the inflammatory potential of STBEV, comprising medium/large-STBEV (>200nm) and small-STBEV (<200nm), isolated from LOPE (n=6) and normal (NP) (n=6) placentae via dual-lobe placental perfusion and differential centrifugation.
