Computerized Cognitive Rehabilitation verses Clinician Directed Therapy in mTBI
Authors: Babakhanyan I , Jensen M , Kim D , West H , Morrissy E , Powell b , Sargent P , Bailie J 
Published: August 2019

Abstract

Background
Cognitive problems following mTBI are common and typically managed with one-on-one clinician directed treatment (CDT); however, this is time and labor intensive. Computerized cognitive rehabilitation (CCR) programs overcome these limitation but the comparable efficacy is not well understood in mTBI.

Method
A randomized controlled trial included 13 active duty service members with a history of mTBI and persistent cognitive complaints. Participants received either CCR (N = 6) or CDT (N = 7) during the initial phase of this study. Treatments were one hour, 3 times a week for 4 weeks. Average age was 32.77 (SD = 7.96). Average intelligence estimated by word reading was average (WTAR M = 107.46, SD = 9.32). Specific measures for attention included Symbol Digit Modality Test (SDMT), Paced Auditory Serial Addition Test (PASAT), Conners Continuous Performance Test (CPT-3), as well as Digit Forward (DF), Digit Backward, and Driving from the Neuropsychological Assessment Battery (NAB). Standard scores corrected for age were analyzed. Change scores were computed between pre and post intervention.

Results
There was a significant difference for SDMT (p = 0.034, d = 1.342) and DF (p = 0.0015, d = 2.33), where those who received CDT showed greater improvement. The groups did not differ on Driving, PASAT, CPT-3, and DB (p’s > 0.62).

Conclusions
Preliminary analysis of data suggests that clinician directed treatment was superior to a computerized intervention matched for time and intensity in treating patients with persistent cognitive complaints following mTBI. Large effects were observed on measures of processing speed and focused attention. This may suggest computerized treatment alone is less effective though further data is needed.

Abstract

Objective
Research examining the course of Alzheimer’s disease (AD) in Hispanics is lacking. This study examined demographic, psychiatric, cognitive, and genetic predictors of longitudinal functional change in Hispanics and non-Hispanics with AD.

Method
Longitudinal change in instrumental activities of daily living (IADL) was examined over 10 years (M = 4.15 years) in 292 subjects (Hispanic = 67, non-Hispanic = 225). All were part of the Texas Alzheimer’s Research & Care Consortium and included those with AD (n = 217) and those with mild cognitive impairment at baseline who progressed to AD at follow-up (n = 75). Baseline comparisons were conducted between ethnic groups for demographics, Geriatric Depression Scale (GDS-30) score, Mini Mental State Examination (MMSE) score, presence of apolipoprotein ɛ4 alleles (APOE4), and annualized IADL change scores and then entered into a multiple linear regression model as predictors of annualized IADL change.

Results
The Hispanic group had significantly more females (χ2 = 5.71, p = .017), lower education [MH = 9.96(4.39), MNH = 15.26(2.70)], higher depression scores [GDS-30; MH = 9.45(5.89), MNH = 5.51(4.29)], lower MMSE scores [MH = 23.31(4.33), MNH = 24.65(3.21)], and slower annualized IADL change [MH = 1.19(1.42), MNH = 2.02(1.60)]. Regression results were significant (F = 3.66, p = .001, R2 = .08 ), with higher baseline MMSE (p = .007) and Hispanic origin (p = .010) predicting slower annualized IADL change. Demographics, APOE4 status, and depression did not significantly predict IADL change.

Conclusions
Higher cognitive functioning at baseline and Hispanic origin was associated with slower functional decline over an average 4-year period of time. Despite having lower MMSE scores at baseline, greater depression, and less education, the Hispanic group had a slower decline in IADLs compared to non-Hispanics. Further research is needed to better understand how/why Hispanic origin is associated with slower functional decline.

Abstract

Objective
With over 37 million Spanish-speakers, the US is the second country in the world with the largest number of Spanish-speakers. Identification of neurological dysfunction via neuropsychological testing for this language group requires knowledgeable application of available tests and normative data. Accordingly, we investigated whether rates of neurocognitive impairment (NCI) varied based on the Spanish language normative method used.

Method
Participants included 254 healthy native Spanish-speakers (Age: M = 37.3, SD = 10.4; Education: M = 10.7, SD = 4.3; 59% Female; 78.7% of known Mexican origin/descent) living in the US-Mexico border region. Participants completed the Hopkins Verbal Learning Test-Revised (HVLT-R), Trail Making Test (TMT) A&B, and Animal Naming in Spanish. Raw test scores were converted to demographically-adjusted T-scores based on normative adjustments developed for this population (Neuropsychological Norms for the US-Mexico Border Region in Spanish [NP-NUMBRS]) and norms developed based on samples in Mexico (Latin American Norms from Mexico [LAN-M] and NEUROPSI). Rates of NCI (T < 40) based on the different normative methods were compared via McNemar’s tests.

Results
Rates of NCI for NP-NUMBRS and NEUROPSI fell between the expected 15-17%. Compared to NP-NUMBRS, significantly lower rates were found when applying LAN-M for HVLT-R Total (4%) and Delayed Recall (8%), TMT-A (1%), and Animal Naming (10%; all ps < .0002). No significant differences were found for TMT-B (p > .05).

Conclusions
Present findings revealed that while the NP-NUMBRS and NEUROPSI norms yielded similar NCI rates, and LAN-M norms underestimated NCI on three tests. This highlights the importance of carefully considering available normative adjustments for Spanish-speakers when applying them to specific populations.
AGR - 2 Diagnosis of Posterior Cortical Atrophy Through Inter-Departmental Collaboration
Authors: John S , Silva M , Newman N , Loring D 
Published: August 2019

Abstract

Objective
We present a patient with rapidly progressive visual decline of 2-year duration that interfered with daily functioning. She was evaluated by neuro-ophthalmology and neurology prior to neuropsychological referral. A series of evaluations led to diagnosis of posterior cortical atrophy, demonstrating the importance of inter-departmental collaboration.

Method
A 66-year old white female presented with a 2-year history of progressive changes to vision and memory. Medical history included hypertension, dyslipidemia, and a strong family history of optic neuropathy causing blindness. She was diagnosed with a left homonymous hemianopia. MRI revealed "significant cortical atrophy more remarkable on the right temporal, parietal, and occipital regions." She reported dressing apraxia, unsteady gait, declines in reading and writing, and difficulty recalling well-learned information.

Results
She was a good historian, had fluent speech and no apparent comprehension difficulty. Neuropsychological evaluation revealed relatively preserved language and verbal abilities, including confrontation naming, in the presence of otherwise impaired performances across all domains of functioning. She demonstrated agraphia, acalculia, left-right confusion, and difficulties with motor programming. Perceptual and constructional tasks revealed prominent deficits in visual integration, map orientation, form discrimination, and construction of simple geometric designs. She was perseverative and susceptible to verbal and visual stimulus pull.

Conclusions
The pattern on neuropsychological testing, with prominent visual spatial and perceptual difficulties, was consistent with posterior cortical atrophy. The decline in visual ability is likely exacerbated but not entirely explained by left hemianopia. Neuropsychological, neuroimaging, and visual field evidence demonstrated posterior cortical atrophy in the absence of positive biomarker evidence, leading to initiation of anti-cholinesterase therapy.
Analysis of several key factors influencing deep learning-based inter-residue contact prediction

Published: August 2019

Abstract

Motivation
Deep learning has become the dominant technology for protein contact prediction. However, the factors that affect the performance of deep learning in contact prediction have not been systematically investigated.

Results
We analyzed the results of our three deep learning-based contact prediction methods (MULTICOM-CLUSTER, MULTICOM-CONSTRUCT and MULTICOM-NOVEL) in the CASP13 experiment and identified several key factors [i.e. deep learning technique, multiple sequence alignment (MSA), distance distribution prediction and domain-based contact integration] that influenced the contact prediction accuracy. We compared our convolutional neural network (CNN)-based contact prediction methods with three coevolution-based methods on 75 CASP13 targets consisting of 108 domains. We demonstrated that the CNN-based multi-distance approach was able to leverage global coevolutionary coupling patterns comprised of multiple correlated contacts for more accurate contact prediction than the local coevolution-based methods, leading to a substantial increase of precision by 19.2 percentage points. We also tested different alignment methods and domain-based contact prediction with the deep learning contact predictors. The comparison of the three methods showed deeper sequence alignments and the integration of domain-based contact prediction with the full-length contact prediction improved the performance of contact prediction. Moreover, we demonstrated that the domain-based contact prediction based on a novel ab initio approach of parsing domains from MSAs alone without using known protein structures was a simple, fast approach to improve contact prediction. Finally, we showed that predicting the distribution of inter-residue distances in multiple distance intervals could capture more structural information and improve binary contact prediction.

Active Sleep Promotes Coherent Oscillatory Activity in the Cortico-Hippocampal System of Infant Rats
Authors: Del Rio-Bermudez Carlos , Kim Jangjin , Sokoloff Greta , Blumberg Mark S 
Published: August 2019

Abstract
Active sleep (AS) provides a unique developmental context for synchronizing neural activity within and between cortical and subcortical structures. In week-old rats, sensory feedback from myoclonic twitches, the phasic motor activity that characterizes AS, promotes coherent theta oscillations (4–8 Hz) in the hippocampus and red nucleus, a midbrain motor structure. Sensory feedback from twitches also triggers rhythmic activity in sensorimotor cortex in the form of spindle bursts, which are brief oscillatory events composed of rhythmic components in the theta, alpha/beta (8–20 Hz), and beta2 (20–30 Hz) bands. Here we ask whether one or more of these spindle-burst components are communicated from sensorimotor cortex to hippocampus. By recording simultaneously from whisker barrel cortex and dorsal hippocampus in 8-day-old rats, we show that AS, but not other behavioral states, promotes cortico-hippocampal coherence specifically in the beta2 band. By cutting the infraorbital nerve to prevent the conveyance of sensory feedback from whisker twitches, cortical-hippocampal beta2 coherence during AS was substantially reduced. These results demonstrate the necessity of sensory input, particularly during AS, for coordinating rhythmic activity between these two developing forebrain structures.
Roy-model bounds on the wage effects of the Great Migration
Authors: Gardner John R 
Published: August 2019

Summary
This paper combines a Roy model of migration and counterfactual wages with racial differences in migration rates during the Great Migration to recover lower bounds on black–white differences in the wage impacts of northward migration. Identification is predicated on the idea that, when migration is more selective for whites, regional wage differentials for whites will be more contaminated with selection bias. In this case, the black–white difference in North–South wage differentials bounds the racial difference in wage impacts from below. Furthermore, as long as the impact of migration on whites’ wages is nonnegative, a lower bound on the black–white difference in wage impacts is also a lower bound on the impact itself for blacks. Applying the identification result, I find that northward migration increased blacks’ wages by at least 36% more than whites’, and hence by at least 36%, on average between 1940 and 1970.

AbstractBackgroundMany European countries do not have comprehensive sexually transmitted infection (STI) surveillance in place. The objective was to investigate whether national probability sample surveys are useful in placing STI surveillance into perspective.MethodsWe used data from the Dutch national cross-sectional probability sample survey on sexual health 2016 (18–34-year-old sexually active individuals). Descriptive analyses were performed regarding STI testing (last year). Test numbers were extrapolated from the survey and compared with surveillance data from sexual health centres (SHCs) (complete) and general practitioners (GPs) (representative estimates from 7% of all GPs). Statistical differences in characteristics between SHC attendees and general population (according to weighted survey participants) were determined using χ2 statistic. Predictors of recent testing at GPs or SHCs were determined using multinomial multivariable logistic regression.ResultsOf the 17 222 survey invitees, 3217 (19%) were eligible for analyses. Testing uptake was higher in women (17.2%, 14.8–20.0%) than men (11.5%, 9.1–14.3%). The majority of tests were conducted by GPs followed by SHCs and hospitals. Number of tests extrapolated from the survey was similar to SHC surveillance data, but higher than GP surveillance data (women only). Testing at SHCs was associated with high-risk behaviour and with living in highly urbanized areas. Low education level and older age were, next to high-risk behaviour factors, determinants of testing at GPs.ConclusionsNational probability sample surveys are useful for placing STI surveillance data into perspective by providing insights in testing patterns in the general population and identifying strengths and weaknesses of national surveillance systems.
Modelling surface NMR spin-echo experiments in a heterogeneous B1 field
Authors: Grombacher Denys 
Published: August 2019

SUMMARY
Surface nuclear magnetic resonance (NMR) measurements show great promise for characterization of subsurface water content, pore-sizes and permeability. The link between surface NMR and pore-size/permeability is founded in the connection between the NMR signal's time dependence and the geometry of the pore-space. To strengthen links between the NMR signal and pore-geometry multipulse surface NMR sequences have been developed to estimate the parameter T2, which carries a strong link to pore-geometry and has formed the basis for NMR-based permeability estimation in the petroleum industry for decades. Producing reliable subsurface characterizations from multipulse surface NMR measurements that measure T2 requires that the forward model is able to accurately predict the transverse magnetization at the time when the measurement occurs. Traditional surface NMR T2 forward models employ an analytic expression for the transverse magnetization, an expression developed in the context of laboratory NMR experiments conducted under conditions significantly different from surface NMR and which require several assumptions to simplify the underlying Bloch equation. To investigate the reliability of this analytic expression under surface NMR conditions, a synthetic comparison is performed where the analytic expression is contrasted against the transverse magnetization predicted from a solution of the full-Bloch equation without the same simplifying assumptions and which can appropriately weight heterogeneity in the applied and background magnetic fields. The comparison shows that the analytic expression breaks down in a range of conditions typical to surface NMR measurements.
The differential impacts of PEPFAR transition on private for-profit, private not-for-profit and publicly owned health facilities in Uganda
Authors: Wilhelm Jess Alan , Paina Ligia , Qiu Mary , Zakumumpa Henry , Bennett Sara 
Published: August 2019

AbstractWhile transition of donor programs to national control is increasingly common, there is a lack of evidence about the consequences of transition for private health care providers. In 2015, President’s Emergency Plan for AIDS Relief (PEPFAR) identified 734 facilities in Uganda for transition from PEPFAR support, including 137 private not-for-profits (PNFP) and 140 private for-profits (PFPs). We sought to understand the differential impacts of transition on facilities with differing ownership statuses. We used a survey conducted in mid-2017 among 145 public, 29 PNFP and 32 PFP facilities reporting transition from PEPFAR. The survey collected information on current and prior PEPFAR support, service provision, laboratory services and staff time allocation. We used both bivariate and logistic regression to analyse the association between ownership and survey responses. All analyses adjust for survey design. Public facilities were more likely to report increased disruption of sputum microscopy tests following transition than PFPs [odds ratio (OR) = 5.85, 1.79–19.23, P = 0.005]. Compared with public facilities, PNFPs were more likely to report declining frequency of supervision for human immunodeficiency virus (HIV) since transition (OR = 2.27, 1.136–4.518, P = 0.022). Workers in PFP facilities were more likely to report reduced time spent on HIV care since transition (OR = 6.241, 2.709–14.38, P &lt; 0.001), and PFP facilities were also more likely to discontinue HIV outreach following transition (OR = 3.029, 1.325–6.925; P = 0.011). PNFP facilities’ loss of supervision may require that public sector supervision be extended to them. Reduced HIV clinical care in PFPs, primarily HIV testing and counselling, increases burdens on public facilities. Prior PFP clients who preferred the confidentiality and service of private facilities may opt to forgo HIV testing altogether. Donors and governments should consider the roles and responses of PNFPs and PFPs when transitioning donor-funded health programs.
Who Speaks and Why? An Examination of Outspokenness on Social Networking Sites and a Reflection on Assessing Public Opinion Online
Authors: Chia Stella C 
Published: August 2019

Abstract
Incorporating the spiral of silence theory and the model of corrective behavior, this study utilized a national survey (N = 373) to investigate the questions of who chooses to speak out on social networking sites (SNSs) and for what reasons in the context of same-sex marriage in Taiwan. Strong partisans were found the most outspoken; they spoke out to prevent media influence that might sway public opinion to the disagreeable side. Only respondents of low attitude extremity would refrain themselves from speaking out on SNSs when perceiving opinion incongruence. Nonpartisans who held a neutral stand could be motivated to speak out when perceiving majority’s support for same-sex marriage. The roles that opinion stances or attitude extremity each play in public opinion process online are discussed.
The Organism as a Whole in an Analysis of Death
Authors: Huang Andrew P , Bernat James L 
Published: August 2019

AbstractAlthough death statutes permitting physicians to declare brain death are relatively uniform throughout the United States, academic debate persists over the equivalency of human death and brain death. Alan Shewmon showed that the formerly accepted integration rationale was conceptually incomplete by showing that brain-dead patients demonstrated a degree of integration. We provide a more complete rationale for the equivalency of human death and brain death by defending a deeper understanding of the organism as a whole (OaaW) and by using a novel strategy with shared objectives to justify death determination criteria. Our OaaW account describes different types of OaaW, defining human death as the loss of status as a human OaaW. We defend human death as similar to nonhuman death in terms of wakefulness, but also distinct in terms of the sui generis properties, particularly conscious awareness. We thereby defend the equivalency of brain death and human death using a resulting neurocentric rationale.
On Pellegrino and Thomasma’s Admission of a Dilemma and Inconsistency
Authors: Kopelman Loretta M 
Published: August 2019

AbstractEdmund Pellegrino and David Thomasma’s writings have had a worldwide impact on discourse about the philosophy of medicine, professionalism, bioethics, healthcare ethics, and patients’ rights. Given their works’ importance, it is surprising that commentators have ignored their admission of an unresolved and troubling dilemma and inconsistency in their theory. The purpose of this article is to identify and state what problems worried them and to consider possible solutions. It is argued that their dilemma stems from their concerns about how to justify professional rules restricting colleagues from performing acts they view as direct, active, and formal (intentional) killings, such as physician-assisted suicide, mercy killing, and abortion. It is further argued that their inconsistency is that they both assert and deny that professional colleagues should not use their moral or theological values to impose professional restrictions on other colleagues without adequate philosophical grounds. At risk are their arguments about the nature of an internal morality for medicine, a secular and multicultural basis for medical ethics, and a nonarbitrary way to determine what acts fall outside the ends of medicine. These are arguments they claim also apply to other healthcare professions. The article begins with a brief overview of their key positions to provide the context in which they make their admission.
