AbstractRational, aims, and objectivesUnderstanding of barriers and successes associated with the implementation of electronic patient self‐reported measures (ePSRMs) within clinical settings are limited and have not been pursued utilizing implementation science frameworks. This qualitative study is designed to assess staff perceptions of an ePSRM implementation.MethodsThe study took place in an academic hospital's Consultation Liaison Psychiatry practice. Qualitative interviews were conducted with the staff and clinicians from the practice. Participants were directly involved with the implementation and use of the ePSRM system within the Psychiatry practice. Interviews were structured around the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE‐AIM) framework.ResultsParticipants reported increased patient engagement as well as efficiency and time savings. The intervention was perceived to be more challenging for older patients. Facilitators include communicating the ePSRM to patients prior to the care visit, having enough trained staff or super‐users who can assist with technical problems, and having a shorter questionnaire.ConclusionsOverall, assessment of the ePSRM implementation was positive. Staff and clinicians indicated benefits in time, effectiveness, and improvements in patient treatment. Results indicate that defining how the system would fit within the clinical workflow was key, as was a flexible and user‐friendly technology platform. The ePSRM implementation was dependent upon clinical involvement and interest in adoption, while barriers were associated with technical challenges as well as some patient difficulties, such as cognitive impairment. The use of the RE‐AIM framework is valuable as it allows for systematic assessment of the implementation and identifies areas in that implementation has succeeded or is lacking.

Abstract Background In 2017, the International Parkinson and Movement Disorder Society put forward new clinical criteria for the diagnosis of PSP, recognizing diverse PSP phenotypes. In this study, we compared the sensitivity and specificity of the new criteria with the National Institutes of Neurological Disease and Society for Progressive Supranuclear Palsy criteria at different times. Methods Patients with clinical parkinsonism, clinical and/or neuropathological diagnosis of PSP, were identified from the Society for Progressive Supranuclear Palsy brain bank. All patients had neuropathologic diagnoses and detailed clinical examination performed by a neurologist at 1 of the 3 Mayo Clinic sites, in Florida, Arizona, and Minnesota. Clinical symptoms and signs were abstracted retrospectively in a blinded fashion and used to determine whether patients met either diagnostic criterion. Patients were divided into early and late disease stage groups using a 3‐year cutoff. Results A total of 129 patients were included, of whom 66 had PSP pathology (51%). The remainder had other neurodegenerative diseases. The overall sensitivity of the International Parkinson and Movement Disorder Society criteria was 87.9%, compared with 45.5% for the National Institutes of Neurological Disease and Society for Progressive Supranuclear Palsy criteria, whereas the specificity of the International Parkinson and Movement Disorder Society probable PSP criteria was 85.7%, compared with 90.5% for the National Institutes of Neurological Disease and Society for Progressive Supranuclear Palsy. Individual patients were noted to have features of multiple PSP phenotypes. Conclusion The International Parkinson and Movement Disorder Society criteria recognize several phenotypes of progressive supranuclear palsy and hence have higher sensitivity than the previous criteria. © 2019 International Parkinson and Movement Disorder Society

Background: Palliative care has been increasingly recognized as an important part of cancer care but remains underutilized in patients with solid cancers. There is a current gap in knowledge regarding why palliative care is underutilized nationwide. Objective: To identify the factors associated with palliative care use among deceased patients with solid cancer tumors. Methods: Using the 2016 National Cancer Data Base, we identified deceased patients (2004-2013) with breast, colon, lung, melanoma, and prostate cancer. Data were described as percentages. Associations between palliative care use and patient, facility, and geographic characteristics were evaluated through multivariate logistic regression. Results: A total of 1 840 111 patients were analyzed; 9.6% received palliative care. Palliative care use was higher in the following patient groups: survival >24 months (17% vs 2%), male (54% vs 46%), higher Charlson-Deyo comorbidity score (16% vs 8%), treatment at designated cancer programs (74% vs 71%), lung cancer (76% vs 28%), higher grade cancer (53% vs 24%), and stage IV cancer (59% vs 13%). Patients who lived in communities with a greater percentage of high school degrees had higher odds of receiving palliative care; Central and Pacific regions of the United States had lower odds of palliative care use than the East Coast. Patients with colon, melanoma, or prostate cancer had lower odds of palliative care than patients with breast cancer, whereas those with lung cancer had higher odds. Conclusions: Palliative care use in solid cancer tumors is variable, with a preference for patients with lung cancer, younger age, known insurance status, and higher educational level.

AbstractBackgroundBlepharospasm (BSP) is a type of focal dystonia characterized by involuntary orbicularis oculi spasms that are usually bilateral, synchronous, and symmetrical. Despite strong evidence for genetic contributions to BSP, progress in the field has been constrained by small cohorts, incomplete penetrance, and late age of onset. Although several genetic etiologies for dystonia have been identified through whole‐exome sequencing (WES), none of these are characteristically associated with BSP as a singular or predominant manifestation.MethodsWe performed WES on 31 subjects from 21 independent pedigrees with BSP. The strongest candidate sequence variants derived from in silico analyses were confirmed with bidirectional Sanger sequencing and subjected to cosegregation analysis.ResultsCosegregating deleterious variants (GRCH37/hg19) in CACNA1A (NM_001127222.1: c.7261_7262delinsGT, p.Pro2421Val), REEP4 (NM_025232.3: c.109C>T, p.Arg37Trp), TOR2A (NM_130459.3: c.568C>T, p.Arg190Cys), and ATP2A3 (NM_005173.3: c.1966C>T, p.Arg656Cys) were identified in four independent multigenerational pedigrees. Deleterious variants in HS1BP3 (NM_022460.3: c.94C>A, p.Gly32Cys) and GNA14 (NM_004297.3: c.989_990del, p.Thr330ArgfsTer67) were identified in a father and son with segmental cranio‐cervical dystonia first manifest as BSP. Deleterious variants in DNAH17, TRPV4, CAPN11, VPS13C, UNC13B, SPTBN4, MYOD1, and MRPL15 were found in two or more independent pedigrees. To our knowledge, none of these genes have previously been associated with isolated BSP, although other CACNA1A mutations have been associated with both positive and negative motor disorders including ataxia, episodic ataxia, hemiplegic migraine, and dystonia.ConclusionsOur WES datasets provide a platform for future studies of BSP genetics which will demand careful consideration of incomplete penetrance, pleiotropy, population stratification, and oligogenic inheritance patterns.

ABSTRACTBackground: Dysregulation of the specialized lipid metabolism involved in myelin synthesis and maintenance by oligodendrocytes has been associated with the unique neuropathology of MSA. We hypothesized that apolipoprotein E, which is associated with neurodegeneration, may also play a role in the pathogenesis of MSA.Objective: This study evaluated genetic associations of Apolipoprotein E alleles with risk of MSA and α‐synuclein pathology, and also examined whether apolipoprotein E isoforms differentially affect α‐synuclein uptake in a oligodendrocyte cell.Methods: One hundred sixty‐eight pathologically confirmed MSA patients, 89 clinically diagnosed MSA patients, and 1,277 control subjects were genotyped for Apolipoprotein E. Human oligodendrocyte cell lines were incubated with α‐synuclein and recombinant human apolipoprotein E, with internalized α‐synuclein imaged by confocal microscopy and cells analyzed by flow cytometry.Results: No significant association with risk of MSA or was observed for either Apolipoprotein E ɛ2 or ɛ4. α‐Synuclein burden was also not associated with Apolipoprotein E alleles in the pathologically confirmed patients. Interestingly, in our cell assays, apolipoprotein E ɛ4 significantly reduced α‐synuclein uptake in the oligodendrocytic cell line.Conclusions: Despite differential effects of apolipoprotein E isoforms on α‐synuclein uptake in a human oligodendrocytic cell, we did not observe a significant association at the Apolipoprotein E locus with risk of MSA or α‐synuclein pathology. © 2018 International Parkinson and Movement Disorder Society
