Social network analysis as a new tool to measure academic impact of physicians.

Introduction: H-index is a widely used metric quantifying a researcher's productivity and impact based on an author's publications and citations. Though convenient to calculate, h-index fails to incorporate collaborations and interrelationships between physicians into its assessment of academic impact, leading to limited insight into grouped networks. We present social network analysis as a tool to measure relationships between physicians and quantify their academic impact.

Yatakemycin biosynthesis requires two deoxyribonucleases for toxin self-resistance.

The highly active natural product yatakemycin (YTM) from sp. TP-A0356 is a potent DNA damaging agent with antimicrobial and antitumor properties. The YTM biosynthesis gene cluster () contains several toxin self-resistance genes.

Anti-inflammatory control of human skin keratinocytes by targeting nuclear transport checkpoint.

Background: In the two common inflammatory skin diseases, Atopic Dermatitis (AD) and Psoriasis (Ps), keratinocytes (KCs) respond to immune insults through activation of proinflammatory transcription factors (TFs) and their translocation to the cell's nucleus. Therein, the TFs induce expression of genes encoding mediators of skin inflammation. The Nuclear Transport Checkpoint Inhibitors (NTCIs) were developed to regulate nuclear translocation of activated TFs, the essential step of inflammatory response.

Characteristics and outcomes of prehospital and emergency department surgical airways.

Objectives: The surgical airway is a high acuity, low occurrence procedure. Data on the complications and outcomes of surgical airways are limited. Our primary objective was to describe immediate complications, late complications, and clinical outcomes of patients who underwent a surgical airway procedure in the prehospital or emergency department (ED) setting.

New directions for Alzheimer's disease research from the Jackson Laboratory Center for Alzheimer's and Dementia Research 2022 workshop.

Introduction: In September 2022, The Jackson Laboratory Center for Alzheimer's and Dementia Research (JAX CADR) hosted a workshop with leading researchers in the Alzheimer's disease and related dementias (ADRD) field.

Methods: During the workshop, the participants brainstormed new directions to overcome current barriers to providing patients with effective ADRD therapeutics. The participants outlined specific areas of focus.

Performance of established disease severity scores in predicting severe outcomes among adults hospitalized with influenza-FluSurv-NET, 2017-2018.

Background: Influenza is a substantial cause of annual morbidity and mortality; however, correctly identifying those patients at increased risk for severe disease is often challenging. Several severity indices have been developed; however, these scores have not been validated for use in patients with influenza. We evaluated the discrimination of three clinical disease severity scores in predicting severe influenza-associated outcomes.

Huntington Study Group's Neuropsychology Working Group: Implementing Non-Motor Diagnostic Criteria.

Background: The clinical diagnosis of manifest Huntington's disease (HD) relies on a high level of clinical confidence (99% confidence) of HD-consistent motor signs. Longitudinal data have reliably identified cognitive and behavioral dysfunction predating clinical motor diagnosis by up to 15 years. Reliance on motor signs to establish a diagnosis of HD increases risk of early misdiagnosis or delayed diagnosis.

From goal to outcome: Analyzing the progression of biomedical sciences PhD careers in a longitudinal study using an expanded taxonomy.

Biomedical sciences PhDs pursue a wide range of careers inside and outside academia. However, there is little data regarding how career interests of PhD students relate to the decision to pursue postdoctoral training or to their eventual career outcomes. Here, we present the career goals and career outcomes of 1452 biomedical sciences PhDs who graduated from Vanderbilt University between 1997 and 2021.

Differential drug response in pulmonary arterial hypertension: The potential for precision medicine.

Pulmonary arterial hypertension (PAH) is a rare, complex, and deadly cardiopulmonary disease. It is characterized by changes in endothelial cell function and smooth muscle cell proliferation in the pulmonary arteries, causing persistent vasoconstriction, resulting in right heart hypertrophy and failure. There are multiple drug classes specific to PAH treatment, but variation between patients may impact treatment response.

Head and Neck Necrotizing Fasciitis: Abbreviated SOFA Score Associated With Death and Infection Spread.

Objective: Describe features unique to head and neck (H&N) necrotizing fasciitis (NF) compared to other anatomic regions and specify a prognostic score associated with death and descending necrotizing mediastinitis (DNM).

Study Design: Retrospective cohort.

Setting: Tertiary care, level 1 trauma center.

Combination anti-obesity medications to effectively treat bariatric surgery weight regain at an academic obesity center.

Background: Combination anti-obesity medications (AOMs) to treat postoperative bariatric surgery weight regain have limited data on their use in the clinical setting. Understanding the optimal treatment protocol in this cohort will maximize weight loss outcomes.

Methods: A retrospective review of bariatric surgery patients ( = 44) presenting with weight regain at a single academic multidisciplinary obesity center who were prescribed AOM(s) plus intensive lifestyle modification for 12 months.

White matter microstructural metrics are sensitively associated with clinical staging in Alzheimer's disease.

Introduction: White matter microstructure may be abnormal along the Alzheimer's disease (AD) continuum.

Methods: Diffusion magnetic resonance imaging (dMRI) data from the Alzheimer's Disease Neuroimaging Initiative (ADNI,  = 627), Baltimore Longitudinal Study of Aging (BLSA,  = 684), and Vanderbilt Memory & Aging Project (VMAP,  = 296) cohorts were free-water (FW) corrected and conventional, and FW-corrected microstructural metrics were quantified within 48 white matter tracts. Microstructural values were subsequently harmonized using the technique and inputted as independent variables to predict diagnosis (cognitively unimpaired [CU], mild cognitive impairment [MCI], AD).

Family resilience and childhood obesity among children exposed to adverse childhood experiences in a national survey.

Objective: Adverse childhood experiences (ACEs) contribute to poor overall health among children with obesity. This study evaluated how one potential protective factor-family resilience-affects the association between ACEs and childhood obesity.

Methods: This analysis was a secondary analysis of the 2016-2018 National Survey of Children's Health (NSCH), a repeated cross-sectional survey based on parent report.

Design of a point-of-care ultrasound curriculum for pediatric emergency medicine fellows: A Delphi study.

Objectives: There has been a steady increase in the growth and utilization of point-of-care ultrasound (POCUS) in pediatric emergency medicine (PEM). POCUS has been established as an Accreditation Council for Graduate Medical Education (ACGME) core requirement for accreditation of PEM fellowship programs. Despite this requirement, training guidelines regarding POCUS knowledge and skills have yet to be developed.

Nebulized albuterol delivery is associated with decreased skeletal muscle strength in comparison with metered-dose inhaler delivery among children with acute asthma exacerbations.

Objective: Albuterol is a β2-agonist and causes an intracellular shift of potassium from the interstitium. Whole-body hypokalemia is known to cause skeletal muscle weakness, but whether this occurs as a result of hypokalemia from the intracellular shift during albuterol treatment is unknown. We sought to determine if albuterol total dose or route of administration (nebulization and/or metered-dose inhaler) is associated with skeletal muscle weakness.

Association of insurance status with potentially avoidable transfers to an academic emergency department: A retrospective observational study.

Background: Interfacility transfers between emergency department (EDs) are common and at times unnecessary. We sought to examine the role of health insurance status with potentially avoidable transfers.

Methods: We conducted a retrospective observational analysis using hospital electronic administrative data of all interfacility ED-to-ED transfers to a single, quaternary care adult ED in 2018.
