Endometrium-Free Closure Technique During Cesarean Delivery for Reducing the Risk of Niche Formation and Placenta Accreta Spectrum Disorders.

Objective: To examine the prevalence and severity of postcesarean residual niche, evaluated using saline infusion sonohysterography, in an expanded cohort of women with one prior cesarean delivery and to assess the effect of uterine closure technique on the risk of placenta accreta spectrum (PAS) disorders.

Methods: This secondary analysis includes 70 patients who underwent saline infusion sonohysterography after one prior cesarean delivery. Patients were grouped according to hysterotomy closure technique: two-layer endometrium-free closure (technique A), and two- or one-layer routine closures (technique B).

Forum: The Past, Present, and Futures of Modern British History.

For the first issue of the renamed journal, Modern British History co-editor Erik Linstrum convened a group of scholars to reflect on the past, present, and possible futures of the field. The resulting contributions make no claim to provide a comprehensive or representative survey. Rather, they offer a variety of perspectives on where modern British history has been and where it might be going.

Assessing the multifaceted cervix: examining cervical gland area at cervical length screening to predict spontaneous preterm birth.

Background: Biologically active cervical glands provide a mucous barrier while influencing the composition and biomechanical strength of the cervical extracellular matrix. Cervical remodeling during ripening may be reflected as loss of the sonographic cervical gland area. As sonographic cervical length remains suboptimal for universal screening, adjunctive evaluation of other facets of the mid-trimester cervix may impart additional screening benefit.

A generic approach to estimate airborne concentrations of substances released by indoor spray processes using a deterministic 2-box model.

Sprays are used both in workplace and consumer settings. Although spraying has advantages, such as uniform distribution of substances on surfaces in a highly efficient manner, it is often associated with a high inhalation burden. For an adequate risk assessment, this exposure has to be reliably quantified.

Root branching under high salinity requires auxin-independent modulation of LATERAL ORGAN BOUNDARY DOMAIN 16 function.

Salinity stress constrains lateral root (LR) growth and severely affects plant growth. Auxin signaling regulates LR formation, but the molecular mechanism by which salinity affects root auxin signaling and whether salt induces other pathways that regulate LR development remains unknown. In Arabidopsis thaliana, the auxin-regulated transcription factor LATERAL ORGAN BOUNDARY DOMAIN 16 (LBD16) is an essential player in LR development under control conditions.

The effect of uterine closure technique on cesarean scar niche development after multiple cesarean deliveries.

Objectives: To use saline infusion sonohysterography (SIS) to evaluate the effect of uterine closure technique on niche formation after multiple cesarean deliveries (CDs).

Methods: Patients with at least one prior CD were evaluated for niche via SIS. Subgroups of any number repeat CD (>1 prior), lower-order CD (<4 prior), and higher-order CD (≥4 prior) were analyzed, stratifying by hysterotomy closure technique at last cesarean preceding imaging; techniques included Technique A (endometrium-free double-layer closure) and Technique B (single- or double-layer routine endo-myometrial closure).

Enhanced recovery after cesarean from the patient perspective: a prospective study of the ERAC Questionnaire (ERAC-Q).

Objectives: To evaluate the impact of an Enhanced Recovery After Cesarean (ERAC) protocol on the post-cesarean recovery experience using a validated ten-item questionnaire (ERAC-Q).

Methods: This is a prospective cohort study of patients completing ERAC quality-of-life questionnaires (ERAC-Q) during inpatient recovery after cesarean delivery (CD) between October 2019 and September 2020, before and after the implementation of our ERAC protocol. Patients with non-Pfannenstiel incision, ICU admission, massive transfusion, bowel injury, existing chronic pain disorders, acute postpartum depression, or neonatal demise were excluded.

Fever, Rash, and Cough in a 7-Year-Old Boy.

A 7-year-old boy presented to the emergency department with fever, cough, congestion, abdominal pain, myalgias, and morbilliform rash. Several aspects of the patient's history, including recent travel, living on a farm, exposure to sick contacts, and new medications, resulted in a wide differential diagnosis. Initial laboratory testing revealed leukocytosis with neutrophilia and elevated atypical lymphocytes, but did not reveal any infectious causes of illness.

Prenatal diagnosis of Bardet Biedl Syndrome: A case report.

The Bardet-Biedl Syndrome (BBS), also called Laurence-Moon-Bardet-Biedl syndrome is a rare ciliopathic autosomal recessive genetic defect. BBS phenotype develops over the years and diagnosis is usually made in late childhood or early adulthood. Prenatal diagnosis is rare in absence of family history or consanguinity.

A mixed-methods evaluation of the ¡Vamos por Más! parenting program implementation in Chile.

Introduction And Aims: Substance use is a significant global concern. Strengthening parenting in families with adolescents has been shown to reduce substance use initiation. The ¡Vamos por Más! (¡VxM!) program is a positive-parenting program developed in Chile to improve family relations and reduce adolescent substance use that combines in-person school workshops, multimedia messaging and personalized support.

A New Model Algorithm for Estimating the Inhalation Exposure Resulting from the Spraying of (Semi)-Volatile Binary Liquid Mixtures (SprayEva).

The spraying of liquid multicomponent mixtures is common in many professional and industrial settings. Typical examples are cleaning agents, additives, coatings, and biocidal products. In all of these examples, hazardous substances can be released in the form of aerosols or vapours.

Exposure modelling in Europe: how to pave the road for the future as part of the European Exposure Science Strategy 2020-2030.

Exposure models are essential in almost all relevant contexts for exposure science. To address the numerous challenges and gaps that exist, exposure modelling is one of the priority areas of the European Exposure Science Strategy developed by the European Chapter of the International Society of Exposure Science (ISES Europe). A strategy was developed for the priority area of exposure modelling in Europe with four strategic objectives.

Theoretical Background of Occupational-Exposure Models-Report of an Expert Workshop of the ISES Europe Working Group "Exposure Models".

On 20 October 2020, the Working Group "Exposure Models" of the Europe Regional Chapter of the International Society of Exposure Science (ISES Europe) organised an online workshop to discuss the theoretical background of models for the assessment of occupational exposure to chemicals. In this report, participants of the workshop with an active role before and during the workshop summarise the most relevant discussion points and conclusions of this well-attended workshop. ISES Europe has identified exposure modelling as one priority area for the strategic development of exposure science in Europe in the coming years.

Increasing Access to Medications for Opioid Use Disorder in Primary Care: Removing the Training Requirement May Not Be Enough.

Background: Substance use disorders, including opioid use disorder (OUD), are understood as chronic diseases with a relapsing and remitting course and no known cure. Medications for OUD (MOUD) are well established with decades of evidence supporting their safety and efficacy; however, treatment access remains poor and inequitable. Buprenorphine is an MOUD that can be prescribed in a primary care outpatient setting, although regulatory and administrative challenges are a barrier to prescribing it.

The Impact of Uterine Incision Closure Techniques on Post-cesarean Delivery Niche Formation and Size: Sonohysterographic Examination of Nonpregnant Women.

Objective: To compare the prevalence and size of residual niche in the nongravid uterus following Cesarean delivery (CD) with different hysterotomy closure techniques (HCTs).

Methods: Saline infusion sonohysterogram (SIS) was performed in women after one prior CD, documenting the presence or absence of a postoperative niche and measuring its depth, width, length, and residual myometrial thickness. Women were grouped by HCT: Technique A (endometrium-free) and Technique B (routine non-endometrium-free).

Association of SARS-CoV-2 placental histopathology findings with maternal-fetal comorbidities and severity of COVID-19 hypoxia.

Objective: SARS-CoV-2 is known to impact multiple organ systems, with growing data to suggest the potential for placental infection and resultant pathology. Understanding how maternal COVID-19 disease can affect placental histopathology has been limited by small study cohorts with mild disease, review by multiple pathologists, and potential confounding by maternal-fetal comorbidities that can also influence placental findings. This study aims to identify pathologic placental findings associated with COVID-19 disease and severity, as well as to distinguish them from changes related to coexisting maternal-fetal comorbidities.

Predictors of severe and critical disease in pregnant women with SARS-CoV-2.

Background/objective: SARS-CoV-2 continues to spread widely in the US and worldwide. Pregnant women are more likely to develop severe or critical illness than their non-pregnant counterparts. Known risk factors for severe and critical disease outside of pregnancy, such as asthma, diabetes, and obesity have not been well-studied in pregnancy.

A cluster randomized trial of interferon ß-1a for the reduction of transmission of SARS-Cov-2: protocol for the Containing Coronavirus Disease 19 trial (ConCorD-19).

Background: SARS-CoV-2 infection rapidly spreads in populations due to the high rates of community transmission. Interrupting the shedding of SARS-CoV-2 may reduce the incidence of Coronavirus Disease 19 (COVID-19). Herein we provide a protocol for a cluster randomized trial that will examine the effectiveness of treatment with interferon (IFN) ß-1a compared to standard of care in limiting the transmission of SARS-CoV-2.
