Impact of sociodemographic status and sex on chronic rhinosinusitis and olfaction in people with cystic fibrosis.

Background: Sociodemographic status (SDS) including race/ethnicity and socioeconomic status as approximated by education, income, and insurance status impact pulmonary disease in people with cystic fibrosis (PwCF). The relationship between SDS and chronic rhinosinusitis (CRS) remains understudied.

Methods: In a prospective, multi-institutional study, adult PwCF completed the 22-Question SinoNasal Outcome Test (SNOT-22), Smell Identification Test (SIT), Questionnaire of Olfactory Disorder Negative Statements (QOD-NS), and Cystic Fibrosis Questionnaire-Revised (CFQ-R).

Can Calcitonin Levels Guide Prophylactic Neck Dissection in Sporadic Medullary Thyroid Carcinoma?

Medullary thyroid carcinoma (MTC) comprises less than 5% of thyroid cancers but is responsible for over 10% of deaths related to thyroid cancer. Regional lymph node metastasis is common and associated with mortality, thus total thyroidectomy with central compartment lymph node dissection is the standard surgical treatment for MTC. In this best practice submission, we aim to review the existing literature and determine whether calcitonin levels can serve as a reliable method for risk-stratifying MTC without overt lymph node involvement.

TEMPORAL CHANGES IN INNATE AND ADAPTIVE IMMUNITY DURING SEPSIS AS DETERMINED BY ELISPOT.

Background: The inability to evaluate host immunity in a rapid quantitative manner in patients with sepsis has severely hampered development of novel immune therapies. The enzyme-linked immunospot (ELISpot) assay is a functional bioassay that measures the number of cytokine-secreting cells and the relative amount of cytokine produced at the single-cell level. A key advantage of ELISpot is its excellent dynamic range enabling a more precise quantifiable assessment of host immunity.

A 22-year single institution review of 119 cases of salivary duct carcinoma.

Objective: Salivary duct carcinoma (SDC) is a rare and aggressive salivary gland malignancy. Herein, we present the largest single-institution review of SDC to date.

Methods: This is a retrospective cohort study of all histologically confirmed cases of SDC seen at our institution from January 1, 2002, to August 1, 2022.

Patient perspectives on chronic rhinosinusitis in cystic fibrosis: Symptom prioritization in the era of highly effective modulator therapy.

Background: Chronic rhinosinusitis (CRS) is common in people with cystic fibrosis (PwCF). Rhinologic symptom prioritization and areas that influence CRS treatment choices, including pursuing endoscopic sinus surgery (ESS), remain understudied.

Methods: Adult PwCF + CRS were enrolled at eight centers into a prospective, observational study (2019-2023).

Determining the minimal clinically important difference for the questionnaire of olfactory disorders in people with cystic fibrosis and factors associated with improvement after highly effective modulator therapy.

Introduction: Olfactory dysfunction (OD) is common among people with cystic fibrosis (PwCF). The Questionnaire of Olfactory Disorders (QOD) is a validated instrument that evaluates olfactory-specific quality-of-life. The QOD minimal clinically important difference (MCID) and factors associated with olfactory improvement after elexacaftor/tezacaftor/ivacaftor have not been determined for PwCF.

Decreases in Rhinology Care Utilization by People with Cystic Fibrosis on Highly Effective Modulator Therapy.

Background: Many people with cystic fibrosis (PwCF) have chronic rhinosinusitis (CRS). CRS requires additional management beyond that of pulmonary disease and leads to increased utilization of healthcare resources. Elexacaftor/tezacaftor/ivacaftor (ETI) is a highly effective modulator therapy that has been shown to improve CRS in PwCF.

Factors that predict pursuing sinus surgery in the era of highly effective modulator therapy.

Background: Comorbid chronic rhinosinusitis (CRS) remains unresolved for many people with cystic fibrosis (PwCF). While highly effective modulator therapy improves quality-of-life and symptom severity, the impact of this intervention and other factors associated with pursuing endoscopic sinus surgery (ESS) remains understudied.

Methods: Adult PwCF + CRS were enrolled into a prospective, observational, multi-institutional study.

Statewide Emergency Medical Services Protocols for Status Epilepticus Management.

Although seizures are common in prehospital settings, standardized emergency medical services (EMS) treatment algorithms do not exist nationally. We examined nationwide variability in status epilepticus treatment by analyzing 33 publicly available statewide EMS protocols. All adult protocols recommend intravenous benzodiazepines (midazolam, n = 33; lorazepam, n = 23; diazepam, n = 24), 30 recommend intramuscular benzodiazepines (midazolam, n = 30; lorazepam, n = 8; diazepam, n = 3), and 27 recommend intranasal benzodiazepines (midazolam, n = 27; lorazepam, n = 3); pediatric protocols also frequently recommend rectal diazepam (n = 14).

A Targeted Mindfulness Curriculum for Medical Students During Their Emergency Medicine Clerkship Experience.

Introduction: Despite high rates of burnout in senior medical students, many schools provide the majority of their wellness training during the first and second preclinical years. Students planning a career in emergency medicine (EM) may be at particularly high risk of burnout, given that EM has one of the highest burnout rates of all the specialties in the United States We developed an innovative, mindfulness-based curriculum designed to be integrated into a standard EM clerkship for senior medical students to help students manage stress and reduce their risk of burnout.

Methods: The curriculum included these components: (1) four, once-weekly, 60-minute classroom sessions; (2) prerequisite reading assignments; (3) individual daily meditation practice and journaling; and (4) the development of a personalized wellness plan with the help of a mentor.

Chimeric antigen receptor-engineered T cells for cancer immunotherapy: progress and challenges.

Recent years have witnessed much progress in both basic research and clinical trials regarding cancer immunotherapy with chimeric antigen receptor (CAR)-engineered T cells. The unique structure of CAR endows T cell tumor specific cytotoxicity and resistance to immunosuppressive microenvironment in cancers, which helps patients to better tackle the issue of immunological tolerance. Adoptive immunotherapy (AIT) using this supernatural T cell have gained momentum after decades of intense debates because of the promising results obtained from preclinical models and clinical trials.

Chimeric antigen receptor containing ICOS signaling domain mediates specific and efficient antitumor effect of T cells against EGFRvIII expressing glioma.

Background: Adoptive transfer of chimeric antigen receptor (CAR)-modified T cells appears to be a promising immunotherapeutic strategy. CAR combines the specificity of antibody and cytotoxicity of cytotoxic T lymphocytes, enhancing T cells' ability to specifically target antigens and to effectively kill cancer cells. Recent efforts have been made to integrate the costimulatory signals in the CAR to improve the antitumor efficacy.

Inhibition of the Wnt-β-catenin and Notch signaling pathways sensitizes osteosarcoma cells to chemotherapy.

Osteosarcoma (OS) is one of the most common malignant bone tumors in early adolescence. Multi-drug chemotherapy has greatly increased the five year survival rate from 20% to 70%. However, the rate has been staggering for 30 years and the prognosis is particularly poor for patients with recurrence and metastasis.
