Innovations for the future of breast surgery.

Background: Future innovations in science and technology with an impact on multimodal breast cancer management from a surgical perspective are discussed in this narrative review. The work was undertaken in response to the Commission on the Future of Surgery project initiated by the Royal College of Surgeons of England.

Methods: Expert opinion was sought around themes of surgical de-escalation, reduction in treatment morbidities, and improving the accuracy of breast-conserving surgery in terms of margin status.

Food Insecurity in an Urban Pregnancy Cohort.

Objective: Food insecurity is a prominent problem and has been implicated in adverse maternal and neonatal outcomes. This study aims to describe the food insecure population in an urban academic health center perinatal cohort.

Study Design: We enrolled 451 postpartum inpatients at the University of Cincinnati Medical Center who completed a questionnaire and were then categorized as food insecure based on U.

Diagnostic shifts in autism spectrum disorder can be linked to the fuzzy nature of the diagnostic boundary: a data-driven approach.

Background: Diagnostic shifts at early ages may provide invaluable insights into the nature of separation between autism spectrum disorder (ASD) and typical development. Recent conceptualizations of ASD suggest the condition is only fuzzily separated from non-ASD, with intermediate cases between the two. These intermediate cases may shift along a transition region over time, leading to apparent instability of diagnosis.

Breast cancer management pathways during the COVID-19 pandemic: outcomes from the UK 'Alert Level 4' phase of the B-MaP-C study.

Background: The B-MaP-C study aimed to determine alterations to breast cancer (BC) management during the peak transmission period of the UK COVID-19 pandemic and the potential impact of these treatment decisions.

Methods: This was a national cohort study of patients with early BC undergoing multidisciplinary team (MDT)-guided treatment recommendations during the pandemic, designated 'standard' or 'COVID-altered', in the preoperative, operative and post-operative setting.

Findings: Of 3776 patients (from 64 UK units) in the study, 2246 (59%) had 'COVID-altered' management.

Safety and adverse events of urgent elective surgery during COVID-19 within three UK hospitals.

This is a cohort study including 283 patients who underwent breast and urological procedures in three UK centres during the peak of COVID-19. COVID-related 30-day mortality was zero, as well as COVID-related admissions. Only 12 patients developed COVID-19 symptoms, although none had a positive COVID swab.

Preoperative nasopharyngeal swab testing and postoperative pulmonary complications in patients undergoing elective surgery during the SARS-CoV-2 pandemic.

Background: Surgical services are preparing to scale up in areas affected by COVID-19. This study aimed to evaluate the association between preoperative SARS-CoV-2 testing and postoperative pulmonary complications in patients undergoing elective cancer surgery.

Methods: This international cohort study included adult patients undergoing elective surgery for cancer in areas affected by SARS-CoV-2 up to 19 April 2020.

Structured oropharynx, hypopharynx and larynx assessment during routine esophagogastroduodenoscopy improves detection of pre- and early cancerous lesions: a multicenter, comparative study.

A structured assessment of the oropharynx, hypopharynx and larynx (OHL) may improve the diagnostic yield for the detection of precancerous and early cancerous lesions (PECLs) during routine esophagogastroduodenoscopy (EGD). Thus, we aimed to compare routine EGDs ± structured OHL assessment (SOHLA), including photo documentation with regard to the detection of PECLs. Consecutive patients with elective EGD were arbitrarily allocated to endoscopy lists with or without SOHLA.

Onset of effect and impact on health-related quality of life, exacerbation rate, lung function, and nasal polyposis symptoms for patients with severe eosinophilic asthma treated with benralizumab (ANDHI): a randomised, controlled, phase 3b trial.

Background: ANDHI was done to assess the efficacy of benralizumab, including onset of effect and impact on health-related quality of life (HRQOL), exacerbation rate, lung function, and nasal polyposis symptoms.

Methods: This phase 3b, randomised, double-blind, parallel-group, placebo-controlled ANDHI study was completed in adults (aged 18-75 years) with severe eosinophilic asthma with at least 2 exacerbations in the previous year, despite high-dose inhaled corticosteroid plus additional controllers, screening blood eosinophil counts of at least 150 cells per μL, and an Asthma Control Questionnaire 6 (ACQ-6) score of 1·5 or more. Patients who met eligibility criteria were randomly assigned (2:1; stratified by previous exacerbation count [two, or three or more], maintenance oral corticosteroid use, and region), using an integrated web-based response system, to receive benralizumab at 30 mg every 8 weeks (first three doses given 4 weeks apart) or matched placebo for 24 weeks.

Predictive Effect of Frailty on Amputation, Mortality, and Ambulation in Patients Undergoing Revascularization for Acute Limb Ischemia.

Background: Frailty is a common, age-associated syndrome that has been used to predict postoperative outcomes in vascular surgery. This study examines if standard measures of frailty correlate with postoperative outcomes for patients undergoing revascularization for acute limb ischemia (ALI).

Methods: A retrospective study was conducted on all adult patients undergoing revascularization for ALI at an academic medical center between January 2016 and June 2019.

Differential Binding of Sarilumab and Tocilizumab to IL-6Rα and Effects of Receptor Occupancy on Clinical Parameters.

We evaluated interleukin-6 (IL-6) receptor-α subunit (IL-6Rα) signaling inhibition with sarilumab and tocilizumab, the association between IL-6Rα receptor occupancy (RO) and C-reactive protein (CRP), and the potential clinical relevance of any differences. For this, we measured IL-6Rα binding and signaling inhibition with sarilumab and tocilizumab in vitro, simulated soluble IL-6Rα RO over time for approved sarilumab subcutaneous (SC) and tocilizumab intravenous (IV) and SC doses, and assessed associations between calculated RO and CRP reduction, 28-joint Disease Activity Score based on CRP, and 20%/50%/70% improvement in American College of Rheumatology responses from clinical data. Sarilumab binds IL-6Rα in vitro with 15- to 22-fold higher affinity than tocilizumab, and inhibits IL-6-mediated classical and trans signaling via membrane-bound and soluble IL-6Rα.

Th1-Polarized, Dengue Virus-Activated Human Mast Cells Induce Endothelial Transcriptional Activation and Permeability.

Dengue virus (DENV), an arbovirus, strongly activates mast cells (MCs), which are key immune cells for pathogen immune surveillance. In animal models, MCs promote clearance of local peripheral DENV infections but, conversely, also promote pathological vascular leakage when widely activated during systemic DENV infection. Since DENV is a human pathogen, we sought to ascertain whether a similar phenomenon could occur in humans by characterizing the products released by human MCs (huMCs) upon direct (antibody-independent) DENV exposure, using the phenotypically mature huMC line, ROSA.

Anterior skull base olfactory tumours, which is what? A case report and review.

Intracranial schwannomas not originating from cranial nerves are rare. In this paper, we report a case of a 50-year-old male who presented with worsening headaches, diplopia and nausea over two years. Radiological imaging revealed a large tumour arising from the olfactory groove region with a preoperative diagnosis of olfactory groove meningioma (OGM).

Limitations of Conventional Magnetic Resonance Imaging as a Predictor of Death or Disability Following Neonatal Hypoxic-Ischemic Encephalopathy in the Late Hypothermia Trial.

Objective: To investigate if magnetic resonance imaging (MRI) is an accurate predictor for death or moderate-severe disability at 18-22 months of age among infants with neonatal encephalopathy in a trial of cooling initiated at 6-24 hours.

Study Design: Subgroup analysis of infants ≥36 weeks of gestation with moderate-severe neonatal encephalopathy randomized at 6-24 postnatal hours to hypothermia or usual care in a multicenter trial of late hypothermia. MRI scans were performed per each center's practice and interpreted by 2 central readers using the Eunice Kennedy Shriver National Institute of Child Health and Human Development injury score (6 levels, normal to hemispheric devastation).

Subcutaneous Sarilumab in Patients With Rheumatoid Arthritis who Previously Received Subcutaneous Sarilumab or Intravenous Tocilizumab: An Open-Label Extension of a Randomized Clinical Trial.

Objective: This post hoc analysis evaluated the safety and efficacy of open-label sarilumab in patients with rheumatoid arthritis (RA) who completed the phase III double-blind ASCERTAIN study (NCT01768572) and switched from intravenous (IV) tocilizumab to subcutaneous (SC) sarilumab, or who continued SC sarilumab in the open-label extension (OLE) study EXTEND (NCT01146652).

Methods: Patients who completed ASCERTAIN were eligible to enroll in EXTEND to receive sarilumab 200 mg SC every 2 weeks (Q2W). Safety and efficacy were reported through 96 weeks in the OLE in patients who switched from tocilizumab IV to sarilumab 200 mg SC Q2W, who switched from sarilumab 150 mg SC Q2W to sarilumab 200 mg SC Q2W, or who continued sarilumab 200 mg SC Q2W.

Towards a Data-Driven Approach to Screen for Autism Risk at 12 Months of Age.

Objective: This study aimed to develop a classifier for infants at 12 months of age based on a parent-report measure (the First Year Inventory 2.0 [FYI]), for the following reasons: (1) to classify infants at elevated risk, above and beyond that attributable to familial risk status for ASD; and (2) to serve as a starting point to refine an approach for risk estimation in population samples.

Method: A total of 54 high-familial risk (HR) infants later diagnosed with ASD (HR-ASD), 183 HR infants not diagnosed with ASD at 24 months of age (HR-Neg), and 72 low-risk controls participated in the study.

Tracheostomy During the COVID-19 Pandemic: Comparison of International Perioperative Care Protocols and Practices in 26 Countries.

Objective: The coronavirus disease 2019 (COVID-19) pandemic has led to a global surge in critically ill patients requiring invasive mechanical ventilation, some of whom may benefit from tracheostomy. Decisions on if, when, and how to perform tracheostomy in patients with COVID-19 have major implications for patients, clinicians, and hospitals. We investigated the tracheostomy protocols and practices that institutions around the world have put into place in response to the COVID-19 pandemic.

Assessment of outcomes of calciphylaxis.

Background: Calciphylaxis is a rare thrombotic vasculopathy characterized by high morbidity and mortality. There is a paucity of studies examining longitudinal outcomes.

Objective: To assess mortality, days spent in the hospital, and amputations in patients with calciphylaxis.

Fetal mast cells mediate postnatal allergic responses dependent on maternal IgE.

Mast cells (MCs) are central effector cells in allergic reactions that are often mediated by immunoglobulin E (IgE). Allergies commonly start at an early age, and both MCs and IgE are detectable in fetuses. However, the origin of fetal IgE and whether fetal MCs can degranulate in response to IgE-dependent activation are presently unknown.

Langer's arch: A rare but important consideration for axillary surgery with implications for training.

Langer's arch (LA), although rare, is an important anatomical anomaly in the axilla that may be encountered during axillary lymph node dissection (ALND). Failure to recognize this anomaly may cause disorientation during ALND, resulting in inadequate clearance, with implications for local disease recurrence and inaccurate staging. Here, we present a case that highlights the confusion LA can cause even in experienced surgeons.

DBT-informed treatment in a partial hospital and intensive outpatient program: the role of step-down care.

Few studies to date have examined Partial Hospital (PH) and Intensive Outpatient (IOP) programs that utilize a Dialectical Behavior Therapy (DBT)-informed model. Preliminary findings suggest that DBT-informed PH programs are effective in reducing clinical symptoms; however, less is known about IOP programs as well as step-down care models. The present study utilized clinically relevant outcome indices and included a heterogeneous clinical sample.
