Derivation and Validation of a Predictive Algorithm for Long-Term Care Admission or Death.

J Am Med Dir Assoc 2021 May 10. Epub 2021 May 10.

Center of Innovation in Long Term Services and Supports, Providence VA Medical Center, Providence, RI, USA; Brown School of Public Health, Providence, RI, USA; Warren Alpert Medical School of Brown University, Providence, RI, USA. Electronic address:

Objectives: Many older Veterans, like most adults, prefer to remain in their homes and communities as long as possible. Although targeted delivery of home- and community-based services for Veterans might delay long-term care placement, often, access to these services is inconsistently organized or delayed. To aid in early recognition of Veterans at high risk for long-term care placement or death, we developed and validated a predictive algorithm, "Choose Home. Read More

Infratentorial pathology in frontotemporal dementia: cerebellar grey and white matter alterations in FTD phenotypes.

J Neurol 2021 May 13. Epub 2021 May 13.

Computational Neuroimaging Group, Trinity Biomedical Sciences Institute, Trinity College Dublin, Peter Bede, Room 5.43, Pearse Street, Dublin 2, Ireland.

The contribution of cerebellar pathology to cognitive and behavioural manifestations is increasingly recognised, but the cerebellar profiles of FTD phenotypes are relatively poorly characterised. A prospective, single-centre imaging study has been undertaken with a high-resolution structural and diffusion tensor protocol to systematically evaluate cerebellar grey and white matter alterations in behavioural-variant FTD(bvFTD), non-fluent variant primary progressive aphasia(nfvPPA), semantic-variant primary progressive aphasia(svPPA), C9orf72-positive ALS-FTD(C9 + ALSFTD) and C9orf72-negative ALS-FTD(C9-ALSFTD). Cerebellar cortical thickness and complementary morphometric analyses were carried out to appraise atrophy patterns controlling for demographic variables. Read More

Clin Orthop Relat Res 2021 05 10. Epub 2021 May 10.

G. Xiong, N. E. Greene, H. M. Lightsey, A. M. Crawford, B. M. Striano, Harvard Combined Orthopaedic Residency Program, Harvard Medical School, Boston, MA, USA A. K. Simpson, A. J. Schoenfeld, Department of Orthopaedic Surgery, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, USA.

Background: Healthcare disparities are well documented across multiple subspecialties in orthopaedics. The widespread implementation of telemedicine risks worsening these disparities if not carefully executed, despite original assumptions that telemedicine improves overall access to care. Telemedicine also poses unique challenges such as potential language or technological barriers that may alter previously described patterns in orthopaedic disparities. Read More

Clin Orthop Relat Res 2021 05 10. Epub 2021 May 10.

T. J. Rajamäki, A. Hietaharju, E. Jämsen, Faculty of Medicine and Health Technology, Tampere University, Tampere, Finland T. J. Rajamäki, T. Moilanen, E. Jämsen, Coxa Hospital for Joint Replacement, Tampere, Finland P. A. Puolakka, Department of Anaesthesia, Tampere University Hospital, Tampere, Finland A. Hietaharju, Department of Neurology, Tampere University Hospital, Tampere, Finland.

Background: Mental health disorders can occur in patients with pain conditions, and there have been reports of an increased risk of persistent pain after THA and TKA among patients who have psychological distress. Persistent pain may result in the prolonged consumption of opioids and other analgesics, which may expose patients to adverse drug events and narcotic habituation or addiction. However, the degree to which preoperative use of antidepressants or benzodiazepines is associated with prolonged analgesic use after surgery is not well quantified. Read More

Fine root dynamics across pantropical rainforest ecosystems.

Glob Chang Biol 2021 May 12. Epub 2021 May 12.

Forestry Research Institute of Ghana, Council for Scientific and Industrial Research, University, P.O. Box 63, Kumasi, Ghana.

Fine roots constitute a significant component of the net primary productivity (NPP) of forest ecosystems but are much less studied than above-ground NPP. Comparisons across sites and regions are also hampered by inconsistent methodologies, especially in tropical areas. Here, we present a novel dataset of fine root biomass, productivity, residence time, and allocation in tropical old-growth rainforest sites worldwide, measured using consistent methods, and examine how these variables are related to consistently determined soil and climatic characteristics.

Subterranean movement inferred by temporary emigration in Barton Springs salamanders ().

PeerJ 2021 23;9:e11246. Epub 2021 Apr 23.

Watershed Protection Department, City of Austin, Austin, TX, United States of America.

Movement behavior is an important aspect of animal ecology but is challenging to study in species that are unobservable for some portion of their lives, such as those inhabiting subterranean environments. Using four years of robust-design capture-recapture data, we examined the probability of movement into subterranean habitat by a population of endangered Barton Springs salamanders (), a species that inhabits both surface and subterranean groundwater habitats. We tested the effects of environmental variables and body size on survival and temporary emigration, using the latter as a measure of subterranean habitat use. Read More

Identifying biotic drivers of population dynamics in a benthic-pelagic community.

Ecol Evol 2021 May 28;11(9):4035-4045. Epub 2021 Mar 28.

Environmental and Marine Biology Åbo Akademi University Turku Finland.

Benthic species and communities are linked to pelagic zooplankton through life-stages encompassing both benthic and pelagic habitats and through a mutual dependency on primary producers as a food source. Many zooplankton taxa contribute to the sedimentary system as benthic eggs. Our main aim was to investigate the nature of the population level biotic interactions between and within these two seemingly independent communities, both dependent on the pelagic primary production, while simultaneously accounting for environmental drivers (salinity, temperature, and oxygen conditions).

Combining radiomic phenotypes of non-small cell lung cancer with liquid biopsy data may improve prediction of response to EGFR inhibitors.

Sci Rep 2021 May 11;11(1):9984. Epub 2021 May 11.

Department of Radiology, University of Pennsylvania, Philadelphia, PA, 19104, USA.

Among non-small cell lung cancer (NSCLC) patients with therapeutically targetable tumor mutations in epidermal growth factor receptor (EGFR), not all patients respond to targeted therapy. Combining circulating-tumor DNA (ctDNA), clinical variables, and radiomic phenotypes may improve prediction of EGFR-targeted therapy outcomes for NSCLC. This single-center retrospective study included 40 EGFR-mutant advanced NSCLC patients treated with EGFR-targeted therapy. Read More

Rural Veterans' Experiences With Outpatient Care in the Veterans Health Administration Versus Community Care.

Med Care 2021 Jun;59(Suppl 3):S286-S291

VA Boston Healthcare System.

Background: The 2014 Veterans Access, Choice and Accountability Act was intended to improve Veterans' access to timely health care by expanding their options to receive community care (CC) paid for by the Veterans Health Administration (VA). Although CC could particularly benefit rural Veterans, we know little about rural Veterans' experiences with CC.

Objective: The objective of this study was to compare rural Veterans' experiences with CC and VA outpatient health care services to those of urban Veterans and examine changes over time. Read More
