Development of a residents' needs assessment-based novel pathology residency boot camp designed on the graduated release of responsibility model.

Boot camps in medical education have emerged as effective tools for addressing knowledge gaps and facilitating the integration of incoming residents into clinical training. We developed a pathology boot camp designed on a needs assessment survey, the graduated release of responsibility model, and active involvement of senior residents as educators. A comprehensive survey was administered to current first-year residents to assess educational needs to identify significant knowledge gaps and difficult areas.

Sudden Death in Pediatric Patient With Dilated Cardiomyopathy Due to Founder Variant in : Case Report.

The gene encodes a transcription factor that plays a role in atrioventricular nodal and myocardial development. Pathogenic variants of are associated with congenital heart disease and sudden cardiac death. The missense variant in this case is one of the more common ones in Northern Europe and has high penetrance in familial cases.

The next phase in patient safety education: Towards a standardized, tools-based pathology patient safety curriculum: ' .

Patient safety education is a mandated Common Program Requirement of the Accreditation Council for Graduate Medical Education and for the Royal College of Physicians and Surgeons of Canada in all medical residency and fellowship programs. Although many hospitals and healthcare environments have general patient safety education tools for trainees, few to none focus on the unique training milieu of pathologists, including a mix of highly automated and manual error-prone processes, frequent multiplicity of events, and lack of direct patient relationships for error disclosure. We established a national Association of Pathology Chairs-Program Directors Section Workgroup focused on patient safety education for pathology trainees entitled Training Residents in Patient Safety (TRIPS).

Evaluating global Vaccinium germplasm for resistance against invasive Drosophila suzukii (Diptera: Drosophilidae).

Control of spotted-wing Drosophila, Drosophila suzukii, in small fruits emphasizes biological, cultural, and chemical approaches, whereas studies of host plant resistance as a form of genetic control are just getting underway. The identification of resistance patterns among genotypes of host plants whose fruit, leaves, roots, stems, or seeds are specifically targeted by an invasive pest is the first step in the development of an effective genetic control. Therefore, a detached fruit bioassay was developed to screen for D.

Sensitivity to imidacloprid insecticide varies among some social and solitary bee species of agricultural value.

Pollinator health risks from long-lasting neonicotinoid insecticides like imidacloprid has primarily focused on commercially managed, cavity-nesting bees in the genera Apis, Bombus, and Osmia. We expand these assessments to include 12 species of native and non-native crop pollinators of differing levels of body size, sociality, and floral specialization. Bees were collected throughout 2016 and 2017 from flowering blueberry, squash, pumpkin, sunflower and okra in south Mississippi, USA.

Molecular genetic characterization of sudden deaths due to thoracic aortic dissection or rupture.

Background: Sudden deaths due to thoracic aortic dissection or rupture (TADR) are often investigated by forensic pathologists in the United States. Up to a quarter of reported TADR result from a highly penetrant autosomal dominant single gene variant. Testing genes associated with familial TADR provides an underlying etiology for the cause of death and informs effective sudden death prevention for at-risk family members.

Insecticidal Activity of Jatropha Extracts Against the Azalea Lace Bug, Stephanitis pyrioides (Hemiptera: Tingidae).

We assessed bioactivity of ethanolic extracts from 35 species of Jatropha L. against an ornamental plant pest, the azalea lace bug, Stephanitis pyrioides (Scott). Jatropha extracts were prepared by air-drying stem, root, or whole plant material, grinding the tissue into a fine powder, adding 70% ethanol, and then vacuum filtering the contents.

Cardiac Arrest in a Softball Player Following a Collision: Catching the Correct Diagnosis.

Commotio cordis is a rare cause of sudden cardiac arrest from blunt chest trauma; however, it is a diagnosis of exclusion. We present a case of sudden cardiac arrest in a collegiate athlete initially attributed to commotio cordis but in whom further history and workup revealed another rare condition. ().

The Role of Amputation and Myoelectric Prosthetic Fitting in Patients with Traumatic Brachial Plexus Injuries.

Background: A cohort of patients with traumatic brachial plexus injuries (BPIs) underwent elective amputation following unsuccessful surgical reconstruction or delayed presentation. The results of amputation with and without a myoelectric prosthesis (MEP) using nonintuitive controls were compared. We sought to determine the benefits of amputation, and whether fitting with an MEP was feasible and functional.

Internal Magnetic Lengthening and Reconstruction with Free TRAM Flap After Traumatic Transfemoral Amputation: A Case Report.

Case: This is a case of a 41-year-old man who sustained a traumatic proximal transfemoral amputation with loss of adductor function and inadequate soft tissue. Wound closure was achieved with split-thickness skin grafting. Subsequently, femoral lengthening was achieved with an internal magnetic lengthening nail.

Using postmortem formalin fixed paraffin-embedded tissues for molecular testing of sudden cardiac death: A cautionary tale of utility and limitations.

For archived cases of previously young healthy individuals where cause of sudden death remains undetermined, formalin fixed paraffin-embedded tissues (FFPE) samples are often the only biological resource available for molecular testing. We aim to ascertain the validity of postmortem molecular analysis of 95 cardiac genes using the FFPE samples routinely processed in the offices of medical examiners - typical fixation time in formalin ranges from days to months. The study was conducted in the College of American Pathologists accredited Molecular Genetics Laboratory within the City of New York Office of Chief Medical Examiner.

Strategies for Reducing Final Surgical Defect Sizes in the Treatment of Lentigo Maligna.

Background: Lentigo maligna (LM) is associated with disproportionately high surgical morbidity.

Objective: The authors report on 2 strategies to reduce the surgical morbidity associated with LM.

Methods: Forty LM lesions were removed with excisional biopsies without margins and closed with purse-string sutures.

Functional characterization of SCN10A variants in several cases of sudden unexplained death.

Background: Multiple genome-wide association studies (GWAS) and targeted gene sequencing have identified common variants in SCN10A in cases of PR and QRS duration abnormalities, atrial fibrillation and Brugada syndrome. The New York City Office of Chief Medical Examiner has now also identified five SCN10A variants of uncertain significance in six separate cases within a cohort of 330 sudden unexplained death events. The gene product of SCN10A is the Nav1.

Case epidemiology from the first three years of a pilot laboratory-based surveillance system for elevated blood-lead concentrations among children in England, 2014-17: implications for public health action.

Background: Children incur lead toxicity even at low blood-lead concentrations (BLCs), and testing in England is opportunistic. We described epidemiology of cases notified to a passive laboratory-based surveillance system (SS), the Lead Poisoning in Children (LPIC) SS to inform opportunities to prevent lead exposure in children in England.

Methods: Surveillance population: children <16 years of age and resident in England during the reporting period September 2014-17.

Paronychia Associated with Ledipasvir/Sofosbuvir for Hepatitis C Treatment.

We present a case of medication-associated paronychia involving multiple toenails in a patient undergoing hepatitis C (HCV) therapy with ledipasvir/sofosbuvir. The patient was treated conservatively with topical mupirocin, clobetasol ointment, and acetic acid soaks, resulting in symptom improvement and control. This topical regimen was maintainined throughout the remaining weeks of the patient's antiviral course, with complete symptom resolution occurring only after completion of his ledipasvir/sofosbuvir treatment.

Functional characterization of ABCC9 variants identified in sudden unexpected natural death.

Background: Genetic variation in ion channel genes ('channelopathies') are often associated with inherited arrhythmias and sudden death. Genetic testing ('molecular autopsies') of channelopathy genes can be used to assist in determining the likely causes of sudden unexpected death. However, different in silico approaches can yield conflicting pathogenicity predictions and assessing their impact on ion channel function can assist in this regard.

Association Between Density of Foraging Bees and Fruit Set in Commercial Fields of Rabbiteye Blueberries (Ericales: Ericaceae) in Louisiana and Mississippi.

Introduction: Thiazide diuretics are among the most widely used antihypertensive medications worldwide. Thiazide-induced hyponatremia (TIH) is 1 of their most clinically significant adverse effects. TIH must result from excessive saliuresis and/or water reabsorption.

Molecular autopsy: using the discovery of a novel de novo pathogenic variant in the KCNH2 gene to inform healthcare of surviving family.

Background: Molecular testing of the deceased (Molecular Autopsy) is an overlooked area in the United States healthcare system and is not covered by medical insurance, leading to ineffective care for surviving families of thousands of sudden unexpected natural deaths each year. We demonstrated the precision management of surviving family members through the discovery of a novel pathogenic variant in a decedent.

Methods: Forensic investigation and molecular autopsy were performed on an 18-year-old female who died suddenly and unexpectedly.

Functional reclassification of variants of uncertain significance in the HCN4 gene identified in sudden unexpected death.

The HCN4 gene encodes a subunit of the hyperpolarization-activated cyclic nucleotide-gated channel, type 4 that is essential for the proper generation of pacemaker potentials in the sinoatrial node. The HCN4 gene is often present in targeted genetic testing panels for various cardiac conduction system disorders and there are several reports of HCN4 variants associated with conduction disorders. Here, we report the in vitro functional characterization of four rare variants of uncertain significance (VUS) in HCN4, identified through testing a cohort of 296 sudden unexpected natural deaths.
