Infraglottal Medialization: Increasing Vocal Fold Stiffness Gradient for Improved Vocal Efficiency.

Objectives/hypothesis: Assess the impact of the infraglottal medialization technique on acoustics and the vertical stiffness gradient of the vocal fold using excised canine larynges.

Methods: Seven ex vivo canine larynges were tested in three states: 1) no implant, 2) medialized using a glottal implant, and 3) medialized fold using an infraglottal implant. Outcome measures were vocal efficiency and stiffness of the fold.

Supplementary oxygen efficacy for chronic pulmonary disorders and exertion desaturation.

Introduction: Exertion-induced desaturation (EID) is a common complication of numerous pulmonary disorders and often treated with supplementary oxygen during exertion. We performed a systematic review and meta-analysis of randomised clinical trials (RCTs) to evaluate the efficacy of supplementary oxygen for EID in pulmonary disorders.

Material And Methods: Medline and Embase were systematically searched from July 2022 to June 2023 following PRISMA guidelines.

Race, ethnicity, and considerations for data collection and analysis in research studies.

Research studies involving human subjects require collection of and reporting on demographic data related to race and ethnicity. However, existing practices lack standardized guidelines, leading to misrepresentation and biased inferences and conclusions for underrepresented populations in research studies. For instance, sometimes there is a misconception that self-reported racial or ethnic identity may be treated as a biological variable with underlying genetic implications, overlooking its role as a social construct reflecting lived experiences of specific populations.

Online, asynchronous training in research for residents.

Scholarly activity is a key component of most residency programmes. To establish fundamental research skills and fill gaps within training curricula, we developed an online, asynchronous set of modules called to introduce trainees to various topics that are germane to the conduct of research and evaluated its effectiveness in resident research education. was utilised by residents at One Brooklyn Health in Brooklyn, NY.

Virilization, Ovarian Hyperthecosis and Torsion Masquerading as Malignancy: A Case Report.

Background: Premenopausal females with signs of androgen excess and oligomenorrhea are commonly evaluated for polycystic ovarian syndrome (PCOS) or for an androgen-secreting tumor if a pelvic mass is present. Ovarian hyperthecosis (OHT) as a cause of these symptoms in adolescents is rare.

Case: A 15-year-old female with primary amenorrhea and signs of virilization was referred to Pediatric and Adolescent Gynecology after pelvic imaging demonstrated a pelvic mass, suspected to be arising from the right ovary, and an adjacent paratubal cyst.

Respiratory Syncytial Virus Disease Burden and Nirsevimab Effectiveness in Young Children From 2023-2024.

Importance: During the 2023-2024 respiratory syncytial virus (RSV) season in the United States, 2 new RSV prevention products were recommended to protect infants in their first RSV season: nirsevimab and Pfizer's maternal RSV vaccine. Postlicensure studies are needed to assess prevention product impact and effectiveness.

Objective: To compare the epidemiology and disease burden of medically attended RSV-associated acute respiratory illness (ARI) among children younger than 5 years during the 2023-2024 RSV season with 3 prepandemic RSV seasons (2017-2020), estimate nirsevimab effectiveness against medically attended RSV-associated ARI, and compare nirsevimab binding site mutations among circulating RSV in infants with and without nirsevimab receipt.

Results from a Double-Blind, Randomized, Placebo-Controlled, Single-Dose, Crossover Trial of Lovastatin or Minocycline in Fragile X Syndrome.

Treatment studies in knockout rodent models have found that minocycline and lovastatin each improve synaptic, neurological, and behavioral functioning, and open-label chronic dosing studies in human patients with fragile X syndrome (FXS) have demonstrated modest clinical improvements. Findings from blinded studies are mixed, and there is a limited understanding of electrophysiological target engagement that would facilitate cross-species translational studies. Smaller-scale, acute (e.

Loss of Cdc42 causes abnormal optic cup morphogenesis and microphthalmia in mouse.

Congenital ocular malformations originate from defective morphogenesis during early eye development and cause 25% of childhood blindness. Formation of the eye is a multi-step, dynamic process; it involves evagination of the optic vesicle, followed by distal and ventral invagination, leading to the formation of a two-layered optic cup with a transient optic fissure. These tissue folding events require extensive changes in cell shape and tissue growth mediated by cytoskeleton mechanics and intercellular adhesion.

Subtype prevalence and treatment implication in adolescents and adults with mild-to-moderate asthma: Systematic review and meta-analysis.

Background: Inhaled corticosteroid (ICS)-containing regimens are the mainstay for treating asthma despite usually being ineffective in noneosinophilic asthma (NEA). Data on the prevalence of NEA versus eosinophilic asthma (EA) in mild-to-moderate asthma are limited.

Objective: We performed a systematic review of the prevalence of mild-to-moderate asthma in adolescents and adults using sputum inflammatory cell analysis and their responses to ICS.

Pseudovirus nanoparticles targeting the receptor binding HA1 domains of influenza viruses elicited high HA1-specific antibody responses and protected mice against mortality caused by influenza virus challenges.

The continually high disease burden of influenza and the relatively low effectiveness of current influenza vaccines call for enhanced vaccine strategies. We previously generated unique S-HA1 pseudovirus nanoparticles (PVNPs) displaying the receptor binding HA1 antigens of the H7N9 subtype as an influenza vaccine candidate and characterized their features in biochemistry, biophysics, structure, and immune response. In this follow up study, we created new S-HA1 PVNPs displaying the HA1 antigens of other common influenza viruses, including two H1N1 strains, one H3N2 strain, and an influenza B virus, respectively.

Hydroxyurea for Children and Adults with Hemoglobin SC Disease.

Background: Hemoglobin SC (HbSC) is a common sickle hemoglobinopathy that causes acute complications, chronic organ damage, and early death with no established disease-modifying treatment. In this trial, we examined the safety and efficacy of hydroxyurea treatment in patients with HbSC.

Methods: Prospective Identification of Variables as Outcomes for Treatment (PIVOT) was a double-blind, randomized, placebo-controlled, non-inferiority phase 2 trial in which we assigned children and adults with HbSC in Ghana to 12 months of hydroxyurea or placebo.

Pulmonary MRI in Newborns and Children.

Lung MRI is an important tool in the assessment and monitoring of pediatric and neonatal lung disorders. MRI can provide both similar and complementary image contrast to computed tomography for imaging the lung macrostructure, and beyond this, a number of techniques have been developed for imaging the key functions of the lungs, namely ventilation, perfusion, and gas exchange, through the use of free-breathing proton and hyperpolarized gas MRI. Here, we review the state-of-the-art in MRI methods that have found utility in pediatric and neonatal lung imaging, the structural and physiological information that can be gleaned from such images, and strategies that have been developed to deal with respiratory (and cardiac) motion, and other technological challenges.

Race and appointment availability influence continuity of care for chronic inflammatory skin disease: A cross-sectional study of United States practice data.

Background: In the management of chronic inflammatory skin disease (CISD), continuity of care may influence the achievement of long-term disease control. Barriers to care have been identified in this population, which may leave some patients more vulnerable to loss of follow-up.

Objective: We aim to identify predictors of continuity of care for CISD patients across demographic groups and health care practice types in the United States.

Outcomes of all-dorsal augmented intercarpal ligament reconstruction (ADAIR).

Background: Scapholunate (SL) and lunotriquetral (LT) ligament injuries are frequently undiagnosed and can lead to progressive loss of wrist function and chronic pain. Many surgical reconstruction options exist, but outcomes are suboptimal and no superior approach has been established.

Methods: Consecutive candidates for SL and/or LT ligament reconstruction utilizing an all-dorsal augmented intercarpal ligament reconstruction (ADAIR) were evaluated in this prospective case series.

Jail-based interventions to reduce risk for opioid-related overdose deaths: Examples of implementation within Ohio counties participating in the HEALing Communities Study.

Background: Opioid-related overdose is a leading cause of death for criminal legal-involved individuals and, although naloxone distribution and medications for opioid use disorder (MOUD) are effective means for reducing post-release overdose death risk, jail-based availability is limited. This case report describes the challenges faced by three Ohio communities as they implemented evidence-based practices (EBPs) in jails to combat post-release opioid overdose deaths.

Method: We present case examples of how barriers were overcome to implement jail-based EBPs in three Ohio communities (two urban and one rural) as part of the HEALing Communities Study (UM1DA049417; ClinicalTrials.

Clinical Outcomes Through Two Years for Infants With Bronchopulmonary Dysplasia and Tracheomalacia.

Background: Tracheomalacia (TM) is common in infants with bronchopulmonary dysplasia (BPD) and associated with respiratory morbidity. Assessment of TM was historically via bronchoscopy, but recent studies demonstrate that ultrashort echo-time (UTE) magnetic resonance imaging (MRI) can accurately assess TM in neonates.

Research Question: Do neonates with MRI-identified TM and BPD have increased respiratory morbidity through age 2 years?

Methods: We performed an observational cohort study of 54 subjects with BPD and assessed TM using UTE MRI at term-equivalent age.

Dermatologist Characteristics Associated With Outlier Performance of Destruction for Benign Lesions.

Background: Destruction of a benign skin lesion should not be billed to Medicare if the lesion is solely a cosmetic concern. Reducing unnecessary benign destructions could lower Medicare costs.

Objective: Evaluate benign destruction rates relative to premalignant destruction rates and identify factors associated with frequent benign destruction among dermatologists.
