Results of a worldwide survey on the currently used histopathological diagnostic criteria for invasive lobular breast cancer.

Invasive lobular carcinoma (ILC) represents the second most common subtype of breast cancer (BC), accounting for up to 15% of all invasive BC. Loss of cell adhesion due to functional inactivation of E-cadherin is the hallmark of ILC. Although the current world health organization (WHO) classification for diagnosing ILC requires the recognition of the dispersed or linear non-cohesive growth pattern, it is not mandatory to demonstrate E-cadherin loss by immunohistochemistry (IHC).

Intervention for Hepatic and Pulmonary Metastases in Breast Cancer Patients: Prospective, Multi-institutional Registry Study-IMET, Protocol MF 14-02.

Background: One fourth of early-stage breast cancer cases become metastatic during the follow-up period. Limited metastasis is a metastatic disease condition in which the number of metastatic sites and the extent of the disease both are limited, and the disease is amenable to metastatic intervention. This prospective study aimed to evaluate intervention for limited metastases in the lung, liver, or both.

Leading Nursing Excellence Through a System Magnet® Program Director Council.

American Nurses Credentialing Center Magnet® designation is prestigious to healthcare institutions. Setting the expectation for all hospitals within a system to be Magnet designated is a lofty but achievable goal. Nursing leaders at the University of Pittsburgh Medical Center set organization-wide designation as a goal in 2010.

Trial of Erythropoietin for Hypoxic-Ischemic Encephalopathy in Newborns.

Background: Neonatal hypoxic-ischemic encephalopathy is an important cause of death as well as long-term disability in survivors. Erythropoietin has been hypothesized to have neuroprotective effects in infants with hypoxic-ischemic encephalopathy, but its effects on neurodevelopmental outcomes when given in conjunction with therapeutic hypothermia are unknown.

Methods: In a multicenter, double-blind, randomized, placebo-controlled trial, we assigned 501 infants born at 36 weeks or more of gestation with moderate or severe hypoxic-ischemic encephalopathy to receive erythropoietin or placebo, in conjunction with standard therapeutic hypothermia.

Structured antenatal milk expression education for nulliparous pregnant people: results of a pilot, randomized controlled trial in the United States.

Background: Hand-expression, collection, and storage of breast milk during pregnancy (i.e., antenatal milk expression or AME) is a safe, potentially effective practice to reduce early, undesired infant formula supplementation among women with diabetes.

What is new in Obstetric Anesthesia in 2020: a focus on research priorities for maternal morbidity, mortality, and postpartum health.

Advances in obstetric anesthesiology have historically exemplified how scientific progress can have a transformational impact on patient safety practices. Profound reductions in anesthesia-related maternal mortality in the 20th century highlighted the specialty of anesthesiology as a leader in safety and care quality. In 2020, maternal health faces new crises: preventable maternal mortality trends worldwide continue to stagnate, and in the United States of America, mortality rates are increasing, attributable to structural care limitations, systemic racism, and social determinants of health.

Reliability and Discriminant Validity of a Checklist for Surgical Scrubbing, Gowning and Gloving.

Background: Surgical scrubbing, gowning, and gloving is challenging for medical trainees to learn in the operating room environment. Currently, there are few reliable or valid tools to evaluate a trainee's ability to scrub, gown and glove. The objective of this study is to test the reliability and validity of a checklist that evaluates the technique of surgical scrubbing, gowning and gloving (SGG).

Association between labor and delivery pain and postpartum pain with symptoms and clinical diagnosis of postpartum depression in patients with overweight and obesity.

Purpose: Childbirth pain has been associated with the risk for postpartum depression. However, existing studies have been limited by the use of depression screening tools as outcomes, and none to date have used a structured clinical interview for DSM-V (SCID), which is considered the gold standard for psychiatric diagnoses. This study aimed to quantify the relationships between labor and postpartum pain and postpartum depression diagnosis detected by SCID, as well as depression symptoms detected by the Center for Epidemiological Studies Depression Scale (CESD) screening tool, among a high-risk cohort.

Abdominal Wall Endometriosis.

Abdominal wall endometriosis (AWE) is a rare type of endometriosis defined as endometrial glands and stroma located within the abdominal wall. Patients with a history of prior abdominal surgery classically present with cyclic abdominal pain and a palpable mass. Definitive diagnosis is made by pathologic tissue examination, but preoperative imaging with ultrasonography or MRI helps narrow the differential and informs surgical management.

Usability, acceptability, and implementation strategies for the Exercise in Cancer Evaluation and Decision Support (EXCEEDS) algorithm: a Delphi study.

Introduction: Oncology guidelines recommend participation in cancer rehabilitation or exercise services (CR/ES) to optimize survivorship. Yet, connecting the right survivor, with the right CR/ES, at the right time remains a challenge. The Exercise in Cancer Evaluation and Decision Support (EXCEEDS) algorithm was developed to enhance CR/ES clinical decision-making and facilitate access to CR/ES.

Operative Time for Minimally Invasive Sacrocolpopexy: Comparison of Conventional Laparoscopy versus Robotic Platform.

Study Objective: To evaluate the operative time for minimally invasive sacrocolpopexy using conventional laparoscopy vs robotic assistance. In addition, we sought to compare intraoperative complications, mesh complications, anatomic prolapse recurrence, and retreatment.

Design: Retrospective cohort study.

Timely cancer genetic counseling and testing for young women with breast cancer: impact on surgical decision-making for contralateral risk-reducing mastectomy.

Purpose: Genetic testing (GT) can identify individuals with pathogenic/likely pathogenic variants (PV/LPVs) in breast cancer (BC) predisposition genes, who may consider contralateral risk-reducing mastectomy (CRRM). We report on CRRM rates in young women newly diagnosed with BC who received GT through a multidisciplinary clinic.

Methods: Clinical data were reviewed for patients seen between November 2014 and June 2019.

Prognostic Significance of Three-Tiered World Health Organization Classification of Phyllodes Tumor and Correlation to Singapore General Hospital Nomogram.

Objectives: Phyllodes tumors (PTs) are categorized by the World Health Organization (WHO) as benign, borderline, and malignant. Singapore General Hospital (SGH) nomogram is a recurrence risk assessment tool for PT, which uses cytologic atypia, mitosis, stromal overgrowth, and the surgical margin status. We studied the prognostic significance of WHO classification and its correlation to the SGH nomogram.

Multi-site observational maternal and infant COVID-19 vaccine study (MOMI-vax): a study protocol.

Background: Pregnant women were excluded from investigational trials of COVID-19 vaccines. Limited data are available to inform pregnant and postpartum women on their decisions to receive a COVID-19 vaccine.

Methods: The goal of this observational, prospective cohort study is to evaluate the immunogenicity and safety of various Emergency Use Authorization (EUA) or licensed COVID-19 vaccines administered to pregnant or lactating women and describe the transplacental antibody transfer and kinetics of antibodies in mothers and infants.

Carrier frequency of autosomal recessive genetic conditions in diverse populations: Lessons learned from the genome aggregation database.

An equitable approach by the American College of Medical Genetics and Genomics (ACMG) has recently recommended carrier screening for genes associated with moderate to severe autosomal recessive conditions with a carrier frequency of ≥1/200 in the Genome Aggregation Database exomes (gnomADv2.0.2).

Clinical-pathologic characteristics and response to neoadjuvant chemotherapy in triple-negative low Ki-67 proliferation (TNLP) breast cancers.

Triple-negative breast cancers (TNBCs) often have a high Ki-67 proliferation index and respond favorably to neoadjuvant chemotherapy (NACT) with pathologic complete response (pCR) resulting in ~40% of cases. Nevertheless, morbidity/mortality remain high, mostly due to recurrence in patients with residual disease. In contrast, the incidence and clinical features of TNBC with low proliferation (TNLP), defined as TNBC with a Ki-67 index of ≤30% remains unknown.

Pharmacologic Management of Interstitial Cystitis/Bladder Pain Syndrome.

Interstitial cystitis/bladder pain syndrome (IC/BPS) is defined as persistent or chronic discomfort perceived to be related to the urinary bladder accompanied by urinary urgency or frequency. Pharmacotherapies used to treat IC/BPS include oral and intravesical agents. Oral therapies include amitriptyline, hydroxyzine, cyclosporine A, and pentosan polysulfate sodium (PPS), although the recent finding of pigmented maculopathy with chronic PPS is very concerning and must be discussed with patients, many of whom will choose to either come off this medicine or not even start it.

3D quantitative analysis of normal clitoral anatomy in nulliparous women by MRI.

Introduction And Hypothesis: We present a 3D computational approach for automated clitoral measurements. We hypothesized that computationally derived measurements would be comparable and less variable than reported manual measures.

Methods: In this retrospective study, MRIs of 22 nulliparous women age 20-49 years with normal vaginal and clitoral anatomy were collected.

Implementation of a universal postpartum blood pressure monitoring program: feasibility and outcomes.

Background: New-onset postpartum preeclampsia has a higher risk of maternal morbidity and mortality than preeclampsia with antepartum onset, underscoring the need for earlier identification of elevated blood pressure among patients with this condition. Given the decrease in healthcare engagement, which is typical of the postpartum period, new-onset postpartum hypertension often goes unrecognized. Currently, there are no recommendations for universal postpartum blood pressure surveillance in women without hypertensive disorders of pregnancy.

Understanding Sociodemographic Disparities in Maternal-Fetal Surgery Study Participation.

Background/purpose: Although maternal-fetal surgery to treat fetal anomalies such as spina bifida continues to grow more common, potential health disparities in the field remain relatively unexamined. To address this gap, we identified maternal-fetal surgery studies with the highest level of evidence and analyzed the reporting of participant sociodemographic characteristics and representation of racial and ethnic groups.

Methods: We conducted a systematic review of the scientific literature using biomedical databases.

International Urogynecological Consultation (IUC): pathophysiology of pelvic organ prolapse (POP).

Introduction And Hypothesis: This manuscript is the International Urogynecology Consultation (IUC) on pelvic organ prolapse (POP) chapter one, committee three, on the Pathophysiology of Pelvic Organ Prolapse assessing genetics, pregnancy, labor and delivery, age and menopause and animal models.

Materials And Methods: An international group of urogynecologists and basic scientists performed comprehensive literature searches using pre-specified terms in selected biomedical databases to summarize the current knowledge on the pathophysiology of the development of POP, exploring specifically factors including (1) genetics, (2) pregnancy, labor and delivery, (3) age and menopause and (4) non-genetic animal models. This manuscript represents the summary of three systematic reviews with meta-analyses and one narrative review, to which a basic scientific comment on the current understanding of pathophysiologic mechanisms was added.

Prospective Evaluation of Coronavirus Disease 2019 (COVID-19) Vaccine Responses Across a Broad Spectrum of Immunocompromising Conditions: the COVID-19 Vaccination in the Immunocompromised Study (COVICS).

Background: We studied humoral responses after coronavirus disease 2019 (COVID-19) vaccination across varying causes of immunodeficiency.

Methods: Prospective study of fully vaccinated immunocompromised adults (solid organ transplant [SOT], hematologic malignancy, solid cancers, autoimmune conditions, human immunodeficiency virus [HIV]) versus nonimmunocompromised healthcare workers (HCWs). The primary outcome was the proportion with a reactive test (seropositive) for immunoglobulin G to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) receptor-binding domain.
