Cochlear implant material effects on inflammatory cell function and foreign body response.

Objectives: The objectives of this study were to assess the effects of cochlear implant (CI) biomaterials on the function of macrophages and fibroblasts, two key mediators of the foreign body response (FBR) and to determine how these materials influence fibrous tissue growth and new bone formation within the cochlea.

Methods: Macrophages and fibroblasts were cultured on polydimethylsiloxane (PDMS) and platinum substrates and human CI electrodes in vitro. Cell count, cell proliferation, cytokine production, and cell adhesion were measured.

Nutritional Concerns among Female International Volunteers Based on the Income and Development Status of Their Country of Service.

This study aimed to determine the prevalence of female athlete triad risk factors among female international volunteers based on the development and income status of their country of service. A total of 2164 past volunteers completed a retrospective survey. Countries' income and development statuses were coded using the respective annual United Nations World Economic Situations and Prospects reports.

Timing of Acoustic Hearing Changes After Cochlear Implantation.

Objectives/hypothesis: To determine the timing of acoustic hearing changes among hearing preservation Cochlear implant (CI) recipients. To determine differences in hearing outcomes based on device type and demographic factors. To determine if there is a relationship between the extent of early hearing loss after CI and the subsequent rate of continued hearing loss.

Endocrine surgeons have high rates of work-related musculoskeletal (MSK) injury and symptoms.

Background: Work-related injury and musculoskeletal (MSK) symptoms are common among surgeons, however data for endocrine surgeons (ES) are lacking.

Methods: A survey was distributed to American Association of Endocrine Surgeons (AAES) and Endocrine section of American Head and Neck Society (AHNS) members.

Results: MSK symptoms were present in 199 (90%) of 220 respondents, most notably pain (91%) and stiffness (81%).

Antifouling and Mechanical Properties of Photografted Zwitterionic Hydrogel Thin-Film Coatings Depend on the Cross-Link Density.

Zwitterionic polymer networks have shown promise in reducing the short- and long-term inflammatory foreign body response to implanted biomaterials by combining the antifouling properties of zwitterionic polymers with the mechanical stability provided by cross-linking. Cross-link density directly modulates mechanical properties (i.e.

Incorporating Surgical Ergonomics Education into Surgical Residency Curriculum.

Background: Education on surgical ergonomics during residency training is lacking. This study aimed to determine the feasibility and impact of incorporating surgical ergonomics lectures into residency curriculum.

Methods: A survey was distributed to 42 residents with questions regarding demographics, surgical factors, prevalence of musculoskeletal (MSK) symptoms, and awareness of ergonomic recommendations.
