Secondary Healing Over NovoSorb BTM in the Management of Complex Nasal Defects.
Plast Reconstr Surg Glob Open
January 2025
Background: The use of PolyNovo NovoSorb biodegradable temporizing matrix (BTM) has become popular for the management of complex wounds, often with the subsequent application of a split-thickness skin graft. To date, there are no published case series describing healing via secondary intention over BTM in the management of small, complex nasal wounds following excision of skin malignancy in the elective setting.
Methods: This study consisted of a single-center, consecutive case series.
Article Synopsis
- The study investigates how MRI-based T relaxation time measurements can detect changes in kidney structure caused by radiation.
- Researchers used two mouse models to expose kidneys to different radiation methods and analyzed MRI results alongside histological and serum biochemistry assessments.
- The findings showed increased T values in specific kidney areas of irradiated mice compared to controls, indicating that MRI can identify radiation damage before other symptoms appear.
Purpose: To optimize a 100 ms pulse for producing CEST MRI contrast and evaluate in mice.
Methods: A gradient ascent algorithm was employed to generate a family of 100 point, 100 ms pulses for use in CEST pulse trains (proton resonance enhancement for CEST imaging and shift exchange). Gradient ascent optimizations were performed for exchange rates = 500, 1500, 2500, 3500, and 4500 s; and labile proton offsets (Δω) = 9.
Objective: To characterize health insurance gap patterns related to age-19 Medicaid and age-26 commercial age-eligibility cutoffs.
Study Setting And Design: This descriptive analysis spans 2014-2018, after Affordable Care Act implementation, but before COVID-19 emergency provisions. We defined insurance gaps as ≥3 consecutive months without observed enrollment, preceded and followed by ≥1 month of enrollment and stratified results by insurance source and clinical severity (e.
Article Synopsis
- Puberty presents unique challenges for individuals with autism spectrum disorder (ASD), including increased vulnerability, safety concerns, and worsened mood and behavioral issues.
- Youth with ASD require targeted education on self-care, hygiene, sexual activity, and menstruation management, but healthcare providers often lack the preparation and confidence to meet these needs.
- A pilot project demonstrated that a brief educational intervention significantly improved family nurse practitioners’ self-reported knowledge and attitudes toward caring for individuals with ASD, highlighting the importance of incorporating such training in nursing education.
