Forensic Linguistics: Science or Fiction?

The history of linguistics is meager and splintered due to the subject’s interdisciplinary nature. In the postwar era, the discipline attempted to revive as a scientific one, spearheaded by Noam Chomsky and his theory of generative grammar. Linguistics consequently broke away from the predominant structuralist approach of the nineteenth century, returning to rationalist roots. But with the rise of computer technology, Chomsky’s critiques of empirical, applicational linguistic approaches have lost their force. As academic linguistics splinters off again, loses its scientific edge, and regroups with the humanities, linguistics applied in the forensic context may implicate more questions than it answers, fundamental questions about humans and language that linguists are still unable to solve: What is language? Do we use language in a way that is uniquely identifiable? Should we look at language use from a societal or individualized, psychological perspective? This Note seeks to reveal these tensions, by providing an overview of the historical development of forensic linguistics; highlights the theory of idiolect backing the use of forensic linguistic evidence; and critiques idiolect and forensic linguistics’ statistical turn in light of linguistics’ ebbing scientific status. As the larger epistemological questions behind forensic linguistic theory remain indeterminate, authorship identification may remain a question of weight, similarity, and difference for judges and juries to grapple with, highlighting the “sliding scale” problem of reliability in the forensic sciences

Emergency Medicine Palliative Care Access (EMPallA): Protocol for a multicentre randomised controlled trial comparing the effectiveness of specialty outpatient versus nurse-led telephonic palliative care of older adults with advanced illness

Introduction Emergency department (ED)-initiated palliative care has been shown to improve patient-centred outcomes in older adults with serious, life-limiting illnesses. However, the optimal modality for providing such interventions is unknown. This study aims to compare nurse-led telephonic case management to specialty outpatient palliative care for older adults with serious, life-limiting illness on: (1) quality of life in patients; (2) healthcare utilisation; (3) loneliness and symptom burden and (4) caregiver strain, caregiver quality of life and bereavement. Methods and analysis This is a protocol for a pragmatic, multicentre, parallel, two-arm randomised controlled trial in ED patients comparing two established models of palliative care: nurse-led telephonic case management and specialty, outpatient palliative care. We will enrol 1350 patients aged 50+ years and 675 of their caregivers across nine EDs. Eligible patients: (1) have advanced cancer (metastatic solid tumour) or end-stage organ failure (New York Heart Association class III or IV heart failure, end-stage renal disease with glomerular filtration rate /min/m2, or global initiative for chronic obstructive lung disease stage III, IV or oxygen-dependent chronic obstructive pulmonary disease); (2) speak English; (3) are scheduled for ED discharge or observation status; (4) reside locally; (5) have a working telephone and (6) are insured. Patients will be excluded if they: (1) have dementia; (2) have received hospice care or two or more palliative care visits in the last 6 months or (3) reside in a long-term care facility. We will use patient-level block randomisation, stratified by ED site and disease. Effectiveness will be compared by measuring the impact of each intervention on the specified outcomes. The primary outcome will measure change in patient quality of life. Ethics and dissemination Institutional Review Board approval was obtained at all study sites. Trial results will be submitted for publication in a peer-reviewed journal

Emergency Medicine Palliative Care Access (EMPallA): Preliminary Data from a Multi-Center Randomized Controlled Trial

Introduction: Emergency department (ED)-initiated palliative care has been shown to improve patient-centered outcomes in older adults with serious illnesses, but the optimal modality for providing such interventions is unknown. The EMPallA trial compares nurse-led, telephonic case management with specialty, outpatient palliative care on: 1) patient quality of life (QOL); 2) healthcare utilization; 3) loneliness and symptom burden; and 4) caregiver strain, QOL, and bereavement. Objective: Summarize preliminary demographic and QOL data for the EMPallA cohort. Methods: A pragmatic, parallel, two-arm randomized controlled trial is enrolling 1350 ED patients across 9 EDs over 3 years to compare the effectiveness of palliative care models. Eligible patients have end-stage heart failure, renal disease, chronic obstructive pulmonary disease (COPD), or cancer. Baseline data is collected at bedside using surveys. Functional Assessment of Cancer Therapy - General (FACT-G) QOL scores are rescaled into T-scores based on general US and cancer patient samples, standardized with mean 50 and standard deviation 10. Results: 138 patients enrolled from April 16 to October 16, 2018. Average age was 69 years; 55% were female, and 55% were white. Advanced cancer was most prevalent (48%), followed by heart failure (24%), COPD (23%), and end-stage renal disease (15%). Average FACT-G T-scores were 41 (general population) and 40 (cancer patients), which are below population means of 50 by more than 5, a clinically-meaningful difference. Discussion: This gender-balanced, racially-diverse cohort stands to benefit in QOL from palliative care. When trial enrollment and follow-up are complete, the impact of interventions can be assessed

The genetic architecture of the human cerebral cortex

The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area cluster near genes in Wnt signaling pathways, which influence progenitor expansion and areal identity. Variation in cortical structure is genetically correlated with cognitive function, Parkinson's disease, insomnia, depression, neuroticism, and attention deficit hyperactivity disorder

Antibodies against endogenous retroviruses promote lung cancer immunotherapy

B cells are frequently found in the margins of solid tumours as organized follicles in ectopic lymphoid organs called tertiary lymphoid structures (TLS). Although TLS have been found to correlate with improved patient survival and response to immune checkpoint blockade (ICB), the underlying mechanisms of this association remain elusive. Here we investigate lung-resident B cell responses in patients from the TRACERx 421 (Tracking Non-Small-Cell Lung Cancer Evolution Through Therapy) and other lung cancer cohorts, and in a recently established immunogenic mouse model for lung adenocarcinoma. We find that both human and mouse lung adenocarcinomas elicit local germinal centre responses and tumour-binding antibodies, and further identify endogenous retrovirus (ERV) envelope glycoproteins as a dominant anti-tumour antibody target. ERV-targeting B cell responses are amplified by ICB in both humans and mice, and by targeted inhibition of KRAS(G12C) in the mouse model. ERV-reactive antibodies exert anti-tumour activity that extends survival in the mouse model, and ERV expression predicts the outcome of ICB in human lung adenocarcinoma. Finally, we find that effective immunotherapy in the mouse model requires CXCL13-dependent TLS formation. Conversely, therapeutic CXCL13 treatment potentiates anti-tumour immunity and synergizes with ICB. Our findings provide a possible mechanistic basis for the association of TLS with immunotherapy response

Development of an Outpatient Palliative Care Protocol to Monitor Fidelity in the Emergency Medicine Palliative Care Access Trial.

Introduction: Palliative care is recommended for patients with life-limiting illnesses; however, there are few standardized protocols for outpatient palliative care visits. To address the paucity of data, this article aims to: (1) describe the elements of outpatient palliative care that are generalizable across clinical sites; (2) achieve consensus about standardized instruments used to assess domains within outpatient palliative care; and (3) develop a protocol and intervention checklist for palliative care clinicians to document outpatient visit elements that might not normally be recorded in the electronic heath record. Methods: As part of a randomized control trial of nurse-led telephonic case management versus specialty, outpatient palliative care in older adults with serious life-limiting illnesses in the Emergency Department, we assessed the structural characteristics of outpatient care clinics across nine participating health care systems. In addition, direct observation of outpatient palliative care visits, consultation from content experts, and survey data were used to develop an outpatient palliative care protocol and intervention checklist. Implementation: The protocol and checklist are being used to document the contents of each outpatient palliative care visit conducted as a part of the Emergency Medicine Palliative Care Access (EMPallA) trial. Variation across palliative care team staffing, clinic session capacity, and physical clinic model presents a challenge to standardizing the delivery of outpatient palliative care
