BACKGROUND: Trials have demonstrated the safety of omitting completion axillary lymph node dissection in patients with cT1-2 N0 breast cancer operated with breast-conserving surgery who have limited metastatic burden in the sentinel lymph node. The aim of this registry study was to provide insight into the oncological safety of omitting completion axillary treatment in patients operated with mastectomy who have limited-volume sentinel lymph node metastasis. METHODS: Women diagnosed in 2013-2014 with unilateral cT1-2 N0 breast cancer treated with mastectomy, with one to three sentinel lymph node metastases (pN1mi-pN1a), were identified from the Netherlands Cancer Registry, and classified by axillary treatment: no completion axillary treatment, completion axillary lymph node dissection, regional radiotherapy, or completion axillary lymph node dissection followed by regional radiotherapy...

INTRODUCTION: Pediatric patients account for 6-10% of emergency medical services (EMS) activations in the United States. Approximately 30% of these children are not transported to an emergency department (ED). Adult data in the literature reports higher hospitalization and complications following non-transport. Few studies discuss epidemiology and characteristics of pediatric non-transport; however, data on outcome is limited. Our primary aim was to determine outcomes of non-transported children within our urban EMS system before and during the COVID-19 pandemic...

Defective brain glucose utilization is a hallmark of Alzheimer's disease (AD) while Type II diabetes and elevated blood glucose escalate the risk for AD in later life. Isolating contributions of normal aging from coincident metabolic or brain diseases could lead to refined approaches to manage specific health risks and optimize treatments targeted to susceptible older individuals. We evaluated metabolic, neuroendocrine, and neurobiological differences between young adult (6 months) and aged (24 months) male rats...

BACKGROUND: Screening for iron deficiency anemia (IDA) is important in managing pediatric patients with inflammatory bowel disease (IBD). Concerns related to adverse reactions may contribute to a reluctance to prescribe intravenous (IV) iron to treat IDA in this population. AIM: To track the efficacy and safety of IV iron therapy in treating IDA in pediatric IBD patients admitted to our center. METHODS: A longitudinal observational cohort study was performed on 236 consecutive pediatric patients admitted to our tertiary IBD care center between September 2017 and December 2019...

Actinobacillus pleuropneumoniae (APP) is a bacterium frequently associated with porcine pleuropneumonia. The acute form of the disease is highly contagious and often fatal, resulting in significant economic losses for pig farmers. Serotype diversity and antimicrobial resistance (AMR) of APP strains circulating in north Italian farms from 2015 to 2022 were evaluated retrospectively to investigate APP epidemiology in the area. A total of 572 strains isolated from outbreaks occurring in 337 different swine farms were analysed...

OBJECTIVE: Periviable rupture of membranes counseling should describe maternal and neonatal outcomes associated with both immediate delivery and expectant management. Unfortunately, most published data focuses on neonatal outcomes and maternal risk estimates vary widely. We performed a meta-analysis to describe outcomes associated with expectant management compared to immediate delivery of periviable PROM. DATA SOURCES: We performed a search on PubMed, MEDLINE, Web of Science, PROSPERO, Cochrane library, and ClinicalTrials...

During the COVID-19 vaccination campaign, observed-to-expected analysis was used by the European Medicines Agency to contextualise data from spontaneous reports to generate real-time evidence on emerging safety concerns that may impact the benefit-risk profile of COVID-19 vaccines. Observed-to-expected analysis compares the number of cases spontaneously reported for an event of interest after vaccination ('observed') to the 'expected' number of cases anticipated to occur in the same number of individuals had they not been vaccinated...

PURPOSE: To understand aspects important to adults with severe cerebral palsy (CP) as they prepare to move from assisted to independent living and to create an appropriate intervention. MATERIALS AND METHODS: An inclusive qualitative study was conducted together with adults with severe CP (Gross Motor Function Classification Scale 4-5) preparing to move to independent living. It included semi-structured interviews which were recorded, transcribed, and analyzed by two occupational therapists to create themes...

A standard curriculum for pediatric colonoscopy training has neither been required nor universally implemented in North American fellowship programs. This qualitative study assessed the needs of colonoscopy training in pediatric gastroenterology to determine the standardized components of procedural teaching. Focus groups with pediatric gastroenterology attendings, fellows, procedural nurses, and interviews with advanced endoscopists, all practicing at a single institution, were conducted between March and June 2018...

Next-generation sequencing (NGS) is increasingly being utilized as an ancillary tool for diagnostically challenging melanocytic neoplasms. It is incumbent upon the pathology community to perform studies assessing the benefits and limitations of these tools in specific diagnostic scenarios. One of the most challenging diagnostic scenarios faced by skin pathologists involves accurate diagnosis of desmoplastic melanocytic neoplasms (DMNs). In this study, 20 expert melanoma pathologists rendered a diagnosis on 47 DMNs based on hematoxylin and eosin sections with demographic information...

OBJECTIVES: Clinical practice guidelines are essential for promoting evidence-based healthcare. While diversification of panel members can reduce disparities in care, processes for panel selection lack transparency. We aim to share our approach in forming a diverse expert panel for the updated Adult Critical Care Ultrasound Guidelines. DESIGN: This process evaluation aims to understand whether the implementation of a transparent and intentional approach to guideline panel selection would result in the creation of a diverse expert guideline panel...

Variant detection from long-read genome sequencing (lrGS) has proven to be considerably more accurate and comprehensive than variant detection from short-read genome sequencing (srGS). However, the rate at which lrGS can increase molecular diagnostic yield for rare disease is not yet precisely characterized. We performed lrGS using Pacific Biosciences "HiFi" technology on 96 short-read-negative probands with rare disease that were suspected to be genetic. We generated hg38-aligned variants and de novo phased genome assemblies, and subsequently annotated, filtered, and curated variants using clinical standards...

BACKGROUND: Individual disease modifying therapies approved for multiple sclerosis (MS) have limited effectiveness and potentially serious side effects, especially when administered over long periods. Sequential combination therapy is a plausible alternative approach. Natalizumab is a monoclonal therapeutic antibody that reduces leukocyte access to the central nervous system that is associated with an increased risk of progressive multifocal leukoencephalopathy and disease reactivation after its discontinuation...

BACKGROUND: Models depicting sexual desire as responsive to sexual arousal may be particularly apt for women experiencing arousal or desire difficulties, and the degree to which arousal triggers desire may depend on the relationship context and desire target and timing-yet, these associations have not been directly tested among women with and without sexual interest/arousal disorder (SIAD). AIM: To assess the role of SIAD status and relationship satisfaction in the associations between genital arousal and 4 types of responsive desire...

Critically ill pediatric patients supported on ventricular assist devices (VADs) are increasingly being anticoagulated on bivalirudin, but with difficulty monitoring anticoagulation. Activated partial thromboplastin time (aPTT) has recently been shown to poorly correlate with bivalirudin plasma concentrations, while dTT had excellent correlation. However, aPTT is the more common monitoring test and dTT testing is rarely used. In addition, effects of frequent clinical VAD scenarios (such as inflammation) on the accuracy of aPTT and dTT testing remains uncertain...

Disrupted sleep is commonly reported during hematopoietic stem cell transplant. In this study, we use actigraphy to measure sleep parameters, and qualitative measures of quality of life, depression, and sleep in pediatric and young adult transplant recipients to describe their time course through transplant. Eight patients had evaluable actigraphy data, and ten patients completed the surveys. The median age of the six male and seven female participants was 13.94 years old. Sleep duration and efficiency measured by actigraphy were suboptimal prior to transplant, then declined to a nadir between Day +7- +14...
