A new species of planthopper in the genus Agoo Bahder & Bartlett (Hemiptera: Fulgoroidea: Derbidae) from coconut palm (Cocos nucifera L.) in Jamaica

A new species of the genus Agoo Bahder & Bartlett, Agoo beani sp. n. was found associated with coconut (Cocos nucifera L., Arecaceae) in Jamaica. This species was discovered as part of a survey of the Caribbean basin to document planthopper diversity on palms. Cytochrome c oxidase subunit I (COI) and 18S sequence data strongly support placement of the new species in Agoo. The morphological features of Omolicna cocoana Rodriguez-Leon & Hidalgo-Gato from Cuba are reviewed and this species transferred into the genus Agoo

Neural Coding of Movement Direction in the Healthy Human Brain

Neurophysiological studies in monkeys show that activity of neurons in primary cortex (M1), pre-motor cortex (PMC), and cerebellum varies systematically with the direction of reaching movements. These neurons exhibit preferred direction tuning, where the level of neural activity is highest when movements are made in the preferred direction (PD), and gets progressively lower as movements are made at increasing degrees of offset from the PD. Using a functional magnetic resonance imaging adaptation (fMRI-A) paradigm, we show that PD coding does exist in regions of the human motor system that are homologous to those observed in non-human primates. Consistent with predictions of the PD model, we show adaptation (i.e., a lower level) of the blood oxygen level dependent (BOLD) time-course signal in M1, PMC, SMA, and cerebellum when consecutive wrist movements were made in the same direction (0° offset) relative to movements offset by 90° or 180°. The BOLD signal in dorsolateral prefrontal cortex adapted equally in all movement offset conditions, mitigating against the possibility that the present results are the consequence of differential task complexity or attention to action in each movement offset condition

Association between longer hospitalization and development of de novo donor specific antibodies in simultaneous liver–kidney transplant recipients

© 2019, © 2019 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group. Background:De novo Donor Specific Antibodies (DSA) are considered as a risk factor for the kidney allograft outcomes in recipients after simultaneous liver–kidney transplantation (SLKT). We hypothesized that length of hospital stay (LOS) might be associated with de novo DSA development of due to the increased likelihood of receiving blood transfusions with reduced immunosuppressive regimens. Methods: This study is a single-center, retrospective cohort study consisting of 85 recipients who underwent SLKT from 2009 to 2018 in our hospital. We divided the patients into two groups according to LOS [long hospital stay (L) group (LOS \u3e14 days) and short hospital stay (S) group (LOS ≤14 days)]. Propensity score (PS) has been created using logistic regression to predict LOS greater than median of 14 days. The association between the presence of de novo DSA and LOS was assessed by logistic regression models adjusted for PS. Results: The mean age at transplantation of the entire cohort was 55.5 ± 10.1 years. Sixty percent of the recipients were male and Caucasian. Median LOS in (L) group was three-fold longer than (S) group [L: median 30 days (IQR: 21–52), S: median 8.5 days (IQR: 7–11)]. Eight patients developed de novo DSA after SLKT (9.4%), all of them were in (L) group. Longer LOS was significantly associated with higher risk of development of de novo DSA in unadjusted (OR+ each 5 days: 1.09, 95% CI:1.02–1.16) and PS adjusted (OR+ each 5 days: 1.11, 95% CI:1.02–1.21) analysis. Conclusion: Longer hospitalization is significantly associated with the development of de novo DSA in SLKT

Racial Differences in Sleep Medication Use: A Cross-Sectional Study of the Johnston County Osteoarthritis Project

Little is known about racial differences in the use of sleep medications

Osteoarthritis and Sleep: The Johnston County Osteoarthritis Project

Objective—Little is known about the association of symptomatic osteoarthritis (OA) with sleep disturbance. We compared the prevalence and severity of current sleep problems among individuals with and without symptomatic hip or knee OA in a large, community-based sample. Methods—Participants (N = 2682, 28% with symptomatic hip or knee OA) were from the Johnston County Osteoarthritis Project. Six sleep variables were grouped into 2 categories: insomnia (trouble falling asleep, trouble staying asleep, or waking early) and insufficient sleep (daytime sleepiness, not enough sleep, or not feeling rested). The presence of any sleep problem (insomnia or insufficient sleep) was also assessed, as were annual frequency and cumulative days of sleep problems. Adjusted models examined associations of symptomatic OA with sleep problems controlling for demographic characteristics, obesity, self-reported health, and depressive symptoms. Results—Symptomatic hip or knee OA was associated with increased odds of any sleep problem (odds ratio 1.25, 95% confidence interval 1.02–1.54), insomnia (OR 1.29, 95% CI 1.07–1.56), and insufficient sleep (OR 1.35, 95% CI 1.12–1.62) in adjusted models. Among participants with sleep problems, those with symptomatic OA reported higher median numbers of annual and cumulative days of insomnia and insufficient sleep, although these associations were not statistically significant in adjusted models. Conclusion—Symptomatic hip and knee OA are significantly associated with sleep problems, independent of other factors related to sleep difficulties, including self-rated health and depression. Patients with OA should be regularly screened for sleep disturbance as part of routine care
