BIOL-0940E: Precision Medicine or Privileged Medicine?

This course proposal and syllabus was conceived and developed by a partnership of the three authors - two undergraduate students and a professor at Brown University. A reflective essay describing our partnership and creative process is in development for publication. This syllabus illustrates many course details that were driven by the student partners' insights and ideas, including the learning outcomes, weekly topics and readings, assignments, active learning elements, and approaches to facilitate agency of the Brown sophomores who subsequently took the course after is was approved in 2018 (BIOL-0940E)

Association between dementia and psychiatric disorders in long-term care residents:An observational clinical study

We examine the relationship between dementia and psychiatric disorder diagnoses among long-term care residents in nursing homes across the state of Rhode Island (RI), USA.Observational clinical study.Two hundred fifty-five residents with and without the diagnosis of dementia were included in this study.Prevalence analysis was used to elucidate information on psychiatric disorders in the overall cohort, and among residents with dementia. Questions from the quality of life questionnaire (EQ-5D-3L) that provides information on self-care, anxiety/depression, and resident's view of how healthy they are, were used to evaluate their association with dementia and psychiatric disorders. A logistic regression analysis was conducted to understand the relationship between dementia and mental illness diagnoses in long-term care facilities. Finally, a subgroup logistic regression analysis was performed for residents with Alzheimer disease.65.1% of all residents suffered from at least 1 psychiatric disorder. Anxiety was the most common diagnosis (36.5%), followed by depression (28.6%), and insomnia (14.9%). There was a positive and statistically significant association between any mental illness diagnosis and dementia (adjusted OR: 3.73; 95% CI: 1.34-10.41). Bipolar disorder and insomnia were negatively and statistically significantly associated with dementia (adjusted OR: 0.17; 95% CI: 0.03-0.89 AND adjusted OR: 0.39; 95% CI: 0.16-0.96 respectively). Age and COPD were also statistically associated with dementia (adjusted OR: 1.07; 95% CI: 1.03-1.11 AND adjusted OR: 0.28, 95% CI: 0.12-0.66). Alzheimer disease was positively and significantly associated with the diagnosis of any mental illness (adjusted OR: 3.77; 95% CI: 1.17-12.20).We studied the relationship between dementia and diagnoses of psychiatric disorders present in long-term care residents. We found that residents with a diagnosis of dementia were more likely to suffer from at least 1 psychiatric disorder. Further work is needed to establish the neuropathophysiological relationship between psychiatric disorders and dementia

The process of obtaining informed consent to research in long term care facilities (LTCFs):An Observational Clinical Study

We examined the process of obtaining informed consent (IC) for clinical research purposes in long-term care facilities (LTCFs) in Rhode Island (RI), USA. We assessed factors that were associated with resident ability to consent, such as Brief Interview for Mental Status scores. We used a self-administered questionnaire to further understand the effect of LTCF staff evaluation of ability to consent on residents' autonomy and control over their medical decision making.Observational clinical studyLong-term care setting.LTCF personnel provided us with residents' names, as well as their professional assessment of resident ability to consent. We used Brief Interview for Mental Status (BIMS) scores to assess the cognitive capacity of all residents to assess, and compare it to the assessment provided by LTCF personnel. A logistic regression analysis was performed to determine the relationship between LTCF assessment of resident ability to consent and BIMS score or confirmed diagnosis of dementia as seen from residents' medical charts. A self-administered questionnaire was filled out by the personnel of 10 LTCFs across RI, USA.LTCF personnel in 9 out of 10 recruited facilities reported that their assessment of resident ability to consent was based on subjective assessment of the resident as alert and oriented. There was a statistically significant relationship between the LTCF assessment of resident ability to consent and previously diagnosed dementia (OR: 0.211, 95% CI 0.107-0.415). Therefore, as BIMS scores increased, the likelihood that the resident would be deemed able to consent by LTCF personnel also increased. Furthermore, there was a statistically significant relationship between LTCF assessment of resident ability to consent and BIMS scores (OR: 1.430, 95% CI 1.274-1.605).There is no standard on obtaining IC for research studies conducted in LTCFs. We recommend that standardizing the process of obtaining IC in LTCFs can enhance the ability to perform research with LTCF residents

A2ML1 and otitis media : novel variants, differential expression, and relevant pathways

A genetic basis for otitis media is established, however, the role of rare variants in disease etiology is largely unknown. Previously a duplication variant within A2ML1 was identified as a significant risk factor for otitis media in an indigenous Filipino population and in US children. In this report exome and Sanger sequencing was performed using DNA samples from the indigenous Filipino population, Filipino cochlear implantees, US probands, Finnish, and Pakistani families with otitis media. Sixteen novel, damaging A2ML1 variants identified in otitis media patients were rare or low-frequency in population-matched controls. In the indigenous population, both gingivitis and A2ML1 variants including the known duplication variant and the novel splice variant c.4061 + 1 G>C were independently associated with otitis media. Sequencing of salivary RNA samples from indigenous Filipinos demonstrated lower A2ML1 expression according to the carriage of A2ML1 variants. Sequencing of additional salivary RNA samples from US patients with otitis media revealed differentially expressed genes that are highly correlated with A2ML1 expression levels. In particular, RND3 is upregulated in both A2ML1 variant carriers and high-A2ML1 expressors. These findings support a role for A2ML1 in keratinocyte differentiation within the middle ear as part of otitis media pathology and the potential application of ROCK inhibition in otitis media.Peer reviewe
