Objective: The Cochlear Osseointegrated Steady-State Implant Bone Anchored Hearing Device (Osia) is a surgically implanted titanium apparatus that utilizes a piezoelectric actuator under the skin to address conductive and mixed hearing loss as well as single-sided deafness. The purpose of this study is to examine the clinical, audiologic, and quality-of-life outcomes in patients who underwent Osia implantation.
Methods: This is a retrospective study analyzing 30 adult patients (age 27-86) with conductive healing loss (CHL), mixed hearing loss (MHL), or single-sided deafness (SSD) who were implanted with the Osia device from January 2020 to April 2023 at a single institution by the senior author. Preoperative speech score testing (CNC, AzBio in quiet, AzBio in noise) were performed in all subjects while unaided, wearing conventional air conduction hearing aids, and wearing a softband BAHA. These preoperative speech scores were then compared to post-implantation speech scores using paired t-test analysis to assess for degree of speech improvement. In order to analyze quality of life after Osia implantation, each patient filled out the Glasgow Benefit Inventory (GBI) survey. The GBI is a series of 18 questions answered using a five-point Likert scale that addresses the changes in general health status, physical health status, psychosocial health status, and social support after a medical intervention.
Results: CHL, MHL, and SSD patients had significant improvement in hearing and speech recognition scores after Osia implantation compared to preoperative unaided hearing: CNC (14 % vs 80 %, p < 0.0001), AzBio in Quiet (26 % vs 94 %, p < 0.0001), and AzBio in Noise (36 % vs 87 %, p = 0.0001). Preoperative speech scores using the softband BAHA were accurate predictors of post-implantation speech scores and can serve to determine surgical candidacy for the Osia. Post-implantation Glasgow Benefit Inventory patient surveys demonstrated significant improvement in quality of life with patients scoring an average increase of +54.1 points in heath satisfaction.
Conclusion: Adult patients with CHL, MHL, and SSD can receive significant improvement in speech recognition scores after implantation with the Osia device. This translates to improved quality of life, which was confirmed on the post-implantation Glasgow Benefit Inventory patient surveys.

The COVID-19 pandemic led to significant shifts in societal norms and individual behaviors, including changes in physical activity levels. This study examines the relationship between socioeconomic and sociodemographic factors and changes in physical activity levels during the pandemic compared to pre-pandemic levels among adult Arkansans. Survey data were collected from 1,205 adult Arkansans in July and August 2020, capturing socioeconomic and sociodemographic characteristics and information on physical activity changes since the onset of the pandemic.

Clear cell renal cell carcinoma (ccRCC) is a highly malignant tumor characterized by a significant propensity for recurrence and metastasis. DNA methylation has emerged as a critical epigenetic mechanism with substantial utility in cancer diagnosis. In this study, multi-omics data were utilized to investigate the target genes regulated by the transcription factor MYC-associated zinc finger protein (MAZ) in ccRCC, leading to the identification of thymidine phosphorylase (TYMP) as a gene with notably elevated expression in ccRCC.

Background: The aim was to assess whether the postoperative Oxford Hip Score (OHS) demonstrated a ceiling effect at 1 or 2 years after total hip arthroplasty (THA) and to identify which patients are more likely to achieve a ceiling score and whether this limits assessment of their outcome.
Methods: A retrospective cohort of 7871 patients undergoing primary THA was identified from an established arthroplasty database. Patient demographics, ASA grade, socioeconomic status, OHS and EuroQol questionnaire were collected preoperatively and at 1 and 2 years postoperatively.

Background: The lack of attention to Chronic Hand Eczema (CHE) and the lack of a specific International Classification of Diseases code for CHE may have limited the assessment of CHE prevalence. To date, prevalence estimates have primarily been derived from (partly small) single-country studies.
Objectives: To estimate the annual prevalence of self-reported physician-diagnosed CHE across socio-demographic characteristics among adults in Canada, France, Germany, Italy, Spain, and the United Kingdom (UK).
