Clinical Productivity and Patient Complexity of Academic Rhinologists: An Analysis of Medicare Metrics.

INTRODUCTION: Current data regarding reimbursement trends in Medicare services and the complexity of patients treated as physicians' progress in their academic career are conflicting. In otolaryngology, there are no data examining these metrics. METHODS: Medicare services, reimbursement, and patient complexity risk scores (based on hierarchical condition category coding) of US rhinology fellowship-trained faculty were stratified and compared by rank and years in practice. RESULTS: A cohort of 209 rhinologists were included. Full professors were reimbursed more per service than assistant professors ($791.53 [$491.69-1052.46] vs. $590.34 [$429.91-853.07] p = 0.045) and had lower risk scores (1.37 [1.26-1.52] vs. 1.49 [1.29-1.68], p = 0.013). Full professors had similar risk scores to associate professors (1.47 [1.25-1.64], p = 0.14). Full professors ($791.53 [$491.69-1,052.46], p < 0.001), associate professors ($706.85 [$473.48-941.15], p < 0.001), and assistant professors ($590.34 [$429.91-853.07], p < 0.001) were all reimbursed more per service than non-ranked faculty ($326.08 [$223.37-482.36]). As a cohort, significant declines in risk scores occurred within the 10th-14th year of practice (p = 0.032) and after the 20th year (p = 0.038). Years in practice were inversely correlated with risk score (R = -0.358, p < 0.001). CONCLUSION: Full professors were reimbursed more per service and treated less comorbid Medicare patients than junior academic colleagues. Patient comorbidity was correlated negatively with years in practice, with significant drops in mid and late career. Rhinologists employed at academic institutions had greater total reimbursement and reimbursement per service than non-ranked faculty. LEVEL OF EVIDENCE: N/A Laryngoscope, 2024.

Research Attitude and Interest among Cancer Survivors with or without Cognitive Impairment.

BACKGROUND: We examined the research attitudes and willingness to participate in clinical research among cancer survivors with varying degrees of cognitive function. METHODS: This is a secondary analysis of data collected through the University of California Irvine Consent-to-Contact registry. Cancer survivors completed the Cognitive Function Instrument (CFI), the Research Attitudes Questionnaire (RAQ), and willingness to participate (WTP) in certain research procedures. Perceived cognitive impairment (CI) was defined as the worst 20% CFI scores. RESULTS: Here, 265 CI and 909 cognitively non-impaired (CNI) participants' data were analyzed. Mean age and sex distribution were similar, with fewer non-Hispanic Whites and education years among CI participants. More CI participants self-reported past diagnoses of Alzheimer's disease, mild cognitive impairment, stroke, depression, post-traumatic stress disorder, and alcohol abuse (all p < 0.05). CI participants were significantly more interested in studies investigating approved medications (92% vs. 87%, p = 0.030), lumbar puncture (47% vs. 38%, p = 0.027), and autopsy (78% vs. 69%, p = 0.022). After removing survivors with co-existing neuropsychiatric conditions, interest in autopsy studies remained statistically higher among CI (79% vs. 69%, p = 0.022). CONCLUSIONS: Participants with cancer and CI are open to research procedures and interventions that are traditionally less utilized, which may facilitate the discovery of the pathogenesis and interventions for cancer-related cognitive impairment (CRCI).

Evidence of brain-derived neurotrophic factor in ameliorating cancer-related cognitive impairment: A systematic review of human studies.

Brain-derived neurotrophic factor (BDNF) plays an essential role in neurogenesis and neuroplasticity and may be a key protein in cancer-related cognitive impairment (CRCI). This systematic review assessed the relationship between BDNF biomarkers and neurocognitive outcomes in cancer patients and survivors. A search in PubMed, Scopus, and PsycINFO yielded 638 articles, of which 26 were eligible. Fourteen (54 %) studied BDNF protein levels while 15 (58 %) analyzed BDNF rs6265 polymorphism. Of the nine observational studies reporting BDNF plasma/serum levels, five (56 %) exhibited a positive association between BDNF and cognitive function. One study reported intra-tumoral BDNF levels that were negatively associated with memory. For rs6265, three (20 %) of 15 studies reported an association with cognitive function with inconsistent directions. Among seven neuroimaging studies, three (43 %) demonstrated an effect of BDNF on brain function and structure. These results suggest that BDNF is a potential monitoring biomarker and druggable target for CRCI.

Reporting adherence, validity and physical activity measures of wearable activity trackers in medical research: A systematic review.

BACKGROUND: Wearable activity trackers are gaining traction in medical research, providing both real-time and remote monitoring of physical fitness. Activity trackers offer an excellent source of personalized physical activity data from patients, as well as healthy individuals, that would provide insights into healthcare analytics and user-feedback on health status. In addition, these activity trackers would also allow researchers to monitor symptom severity and assist clinicians in providing their patients a more holistic care. Despite the promise of wearable device technology, there is still a lack of standardization in the medical literature regarding the analysis and reporting of adherence, validity and physical activity data generated by these activity trackers. OBJECTIVE: We performed a systematic review to identify the activity tracker-derived measures and evaluate the relations of reported adherence, validity, and physical activity types across currently available literature. METHODS: The searches were performed using Pubmed and Embase databases. Studies enrolling at least 1,000 human subjects regardless of health or disease status, using activity trackers of any brand used to track step count, distance, heart rate, energy expenditure or activity intensity, were included. Studies have been published between 2009 to March 2021, with editorials, systematic reviews, meta-analysis, grey literature, validation studies, study protocols and studies using smartphone trackers being excluded. This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. RESULTS: A total of 27 studies met the eligibility criteria and were included in the review, with a total of 514,418 and 1,186,530 subjects recruited in observational and interventional studies, respectively. Apart from ActiGraph (n = 11, 41%), Fitbit (n = 4, 15%) and Axivity (n = 3, 11%) were found to be the most commonly used activity trackers in both types of studies. The wear duration of activity trackers ranged from 1 day to 59 months, with 1 week being the most common length (n = 16, 59%). The most frequently collected physical activity measure was activity intensity (n = 21, 78%), followed by step count (n = 9, 33%) and energy expenditure (n = 2, 7%). Most studies defined a valid day as wear-time of at least 10 h within 1 day (n = 10, 37%), and a valid interval as a week with at least 3 valid days (n = 8, 30%). CONCLUSIONS: This systematic review reveals the diverse analysis and reporting of activity tracker data in the medical literature. Future studies will need to evaluate the feasibility on adopting minimum reporting thresholds of data generated by wearable activity trackers.
