Hearing and dementia

Hearing deficits associated with cognitive impairment have attracted much recent interest, motivated by emerging evidence that impaired hearing is a risk factor for cognitive decline. However, dementia and hearing impairment present immense challenges in their own right, and their intersection in the auditory brain remains poorly understood and difficult to assess. Here, we outline a clinically oriented, symptom-based approach to the assessment of hearing in dementias, informed by recent progress in the clinical auditory neuroscience of these diseases. We consider the significance and interpretation of hearing loss and symptoms that point to a disorder of auditory cognition in patients with dementia. We identify key auditory characteristics of some important dementias and conclude with a bedside approach to assessing and managing auditory dysfunction in dementia

Surgical Games: A Simulation-Based Structured Assessment of Orthopedic Surgery Resident Technical Skill.

BACKGROUND: Simulation-based education and objective evaluation of surgical skill have been incorporated into many surgical training programs. We describe the development and implementation of a timed, multitask, station-based Surgical Games to evaluate orthopedic resident surgical skills. METHODS: Participants in the study were postgraduate-year 2 to 5 orthopedic surgery residents from a single institution. Residents completed 4-timed simulated tasks: cadaveric carpal tunnel release (CTR), Sawbones model of total knee arthroplasty (TKA), Sawbones model of ankle fracture open reduction internal fixation (ORIF), and knee arthroscopy simulator (KAS) of removal of loose body. Evaluations were performed using standardized score sheets by attending surgeons. Resident performance was analyzed by postgraduate-year and number of weeks of prior task-related residency training. RESULTS: A total of 32 residents were assessed at the 4 stations. Total scores were significantly different for CTR (p = 0.006), TKA (p = 0.05), and the KAS (p = 0.004) by year of training, but not for the ankle ORIF task. Residents with more task-specific experience performed significantly better on the KAS (p \u3c 0.001), TKA (p = 0.002), and CTR (p = 0.02) tasks but not on the ankle ORIF task (p = 0.1). Overall, residents rated the exercise valuable to their education with mean scores of 3.9 ± 0.54 on a 5-point Likert Scale. CONCLUSIONS: This Surgical Games exercise provided an objective evaluation of surgical skill that correlated with year-in-training and prior experience in skill-specific rotations for the KAS, TKA, and CTR tasks. This surgical skills assessment provided an opportunity for effective structured feedback and identification of areas for improvement

Postoperative outcomes of total knee arthroplasty compared to unicompartmental knee arthroplasty: A matched comparison

Background: The purpose of this study was to evaluate early postoperative outcomes in patients following UKA (unicompartmental knee arthroplasty) compared to a matched cohort of TKA (total knee arthroplasty) patients. Methods: Patients who met radiographic criteria for a medial UKA who underwent either a TKA or UKA at a single institution were matched based on age, gender, and BMI. Results: One hundredy and fifty UKA in 138 patients and 150 TKA in 148 patients were included in this retrospective analysis. Mean age was 62.6 ± 9 years and 65.2 ± 9 years in the UKA and TKA groups respectively (p = .01). Patients who underwent UKA had significantly less pain at two and six weeks postoperatively compared to TKA patients with mean Numeric Pain Rating Scale (NPRS) scores of 3.7 ± 1.1 vs. 7.8 ± 1.2, p < .001 and 2.6 ± 1.3 vs. 4.6 ± 1.6, p < .001 respectively. Knee Society Scores (KSS) were higher in the UKA group at six weeks and two years postoperative (86.5 ± 2.8 vs. 81.4 ± 3.6, p < .001 and 89.5 ± 2.4 vs. 84.5 ± 3.3, p < .001 respectively). Return to work was faster in the UKA group (mean 20.6 ± 7.89 vs. 38.6 ± 6.23 days, p < .001). The UKA group also had higher mean Forgotten Joint Scores of 90.5 ± 3.6 vs. 79.5 ± 9.5 (p < .001). Conclusions: Patients with primarily medial compartment OA who underwent UKA had less postoperative pain, earlier return to work, and higher KSS compared to a matched group who underwent TKA
