Fatal peste des petits ruminants disease in Chowsingha.

This communication reports fatal Peste des petits ruminants (PPR) disease in Chowsingha (Tetracerus quadricornis), a member of the subfamily Bovinae and family Bovidae captured in a Zoological Park. The animals showed clinical signs of acute respiratory disease with frothy nasal discharge (1-2 days) and mortality of twenty animals (80%) within 48 hr. Necropsy of dead Chowsingha showed haemorrhagic patches in trachea and severe congestion of lungs and ocular mucosa. There was no characteristic lesion in the intestine. Swabs from trachea and nasal tract along with tissue samples of spleen and lung from dead animals were found positive for PPR virus based on reverse transcription-polymerase chain reaction using H gene and partial N gene-specific primers. Sequence analysis of complete H gene and partial N gene confirmed the aetiological agent as PPR virus lineage IV. The identity of the Chowsingha tissues used for PPRV isolation was confirmed by the 12S ribosomal RNA gene sequencing, and the amplified gene was analysed identically to the Chowsingha mitochondrial 12S ribosomal RNA gene. The present information of PPR in Chowsingha is the first report of PPRV lineage IV causing cross-species fatal disease in subfamily bovinae and family Bovidae. The acute manifestation of the disease indicates high susceptibility of this vulnerable wild bovid species to PPR lineage IV. This report extends host range and demands enhanced surveillance among subfamily bovinae to strengthen PPR eradication programme.
Genetic characterization of African swine fever virus isolates from soft ticks at the wildlife/domestic interface in Mozambique and identification of a novel genotype

Summary African swine fever virus (ASFV) is one of the most threatening infectious diseases of pigs. There are not sufficient data to indicate the importance of the sylvatic cycle in the spread and maintenance of the disease locally and potentially, globally. To assess the capacity to maintain ASF in the environment, we investigated the presence of soft tickreservoirs of ASFV in Gorongosa National Park (GNP) and its surrounding villages. A total of 1,658 soft ticks were recovered from warthog burrows and pig pens at the wildlife/livestock interface of the GNP and viral DNA was confirmed by nested PCR in 19% of Ornithodoros porcinus porcinus and 15% of O. p. domesticus. However, isolation of ASFV was only achieved in approximately 50% of the PCR‐positive samples with nineteen haemadsorbing virus isolates recovered. These were genotyped using a combination of partial sequencing of the B646L gene (p72) and analysis of the central variable region (CVR) of the B602L gene. Eleven isolates were classified as belonging to genotype II and homologous to contemporary isolates from southern Africa, the Indian Ocean and eastern Europe. Three isolates grouped within genotype V and were similar to previous isolates from Mozambique and Malawi. The remaining five isolates constituted a new, previously unidentified genotype, designated genotype XXIV. This work confirms for the first time that the virus currently circulating in eastern Europe is likely to have a wildlife origin, and that the large diversity of ASFV maintained in wildlife areas can act as a permanent sources of different strains for the domestic pig value chain in Mozambique and beyond its boundaries. Their genetic similarity to ASFV strains currently spreading across Europe justifies the need to continue studying the sylvatic cycle in this African country and other parts of southern Africa in order to identify potential hot spots of ASF emergence and target surveillance and control efforts.
Identification of a divergent genotype of equine arteritis virus from South American donkeys

A novel equine arteritis virus (EAV) was isolated and sequenced from feral donkeys in Chile. Phylogenetic analysis indicates that the new virus and South African asinine strains diverged at least 100 years from equine EAV strains. The results indicate that asinine strains belonged to a different EAV genotype.
Proactive and retroactive interference in young adults, healthy older adults, and older adults with amnestic mild cognitive impairment

Abstract This study investigated memory interference in amnestic mild cognitive impairment (aMCI) and normal aging. Participants were 27 young adults, 44 healthy older adults, and 15 older adults with aMCI. Memory interference was examined on the California Verbal Learning Test (CVLT) and on a modified AB-AC paradigm. Despite significant differences in memory performance on the CVLT, interference measures on this test did not distinguish individuals with aMCI and healthy older adults. The AB-AC task involved first learning a list (AB list) of 12 semantically related word pairs (e.g., knee-bone). Twenty minutes later, a second list (AC list) was learned in which the same stimulus words were paired with new response words (e.g., knee-bend). Both lists were repeated until 100% accurate recall was achieved. Finally, participants recalled the first (AB) list. Proactive interference (PI) was greater among older than younger adults, and greater still among individuals with aMCI, but the older and aMCI groups showed similar levels of retroactive interference. This study suggests that PI contributes to the memory deficits seen in aMCI and that tests sensitive to PI may assist in the early identification of aMCI. Memory interventions aimed at alleviating PI may improve memory functioning in individuals with aMCI. (JINS, 2009, 15, 83–93.)
Plasma Corticotropin-Releasing Hormone and Cortisol Concentrations and Perceived Stress among Pregnant Women with Preterm and Term Birth

We sought to determine if pregnant women with poor psychosocial status or high levels of perceived stress had higher concentrations of plasma corticotropin-releasing hormone (CRH) or cortisol. This was a secondary analysis of a case-controlled study nested within a multicenter, prospective observational cohort study. Plasma CRH and cortisol concentrations and the Abbreviated Scale for the Assessment of Psychosocial Status in Pregnancy (ASAPS) were available for cases and controls. Among cases and controls, concentrations of CRH and cortisol and overall performance on the ASAPS as well as the individual components of the ASAPS were compared using Kruskal-Wallis or chi-square. There was no association between CRH or cortisol concentrations and performance on the ASAPS overall. Additionally, there was no relationship between CRH or cortisol and perceived stress. In this study, biological measures of stress assessed in the second trimester were not associated with overall psychosocial status or perceived stress. The factors contributing to the elevation in CRH that precedes some preterm birth are complex and poorly understood.
Long-term cognitive function following chemotherapy in patients with testicular cancer

Abstract Cancer patients frequently report cognitive complaints following chemotherapy, but the results from the available studies, mainly of women with breast cancer, are inconsistent. Our aim was to compare cognitive function of men with testicular cancer (TC) who had orchiectomy and chemotherapy (bleomycin, etoposide, cisplatin) with men who had orchiectomy only or orchiectomy and radiotherapy. Thirty-six chemotherapy patients and 36 nonchemotherapy patients were tested 2–7 years after treatment for TC with standardized neuropsychological tests. Chemotherapy and nonchemotherapy patients displayed similar performances on cognitive tests (p values adjusted for multiple comparisons: .63–1.00). Moreover, there was no difference in the proportion of cognitively impaired patients in the chemotherapy group (5.6%) compared to the nonchemotherapy group (8.3%) (χ2 = 0.22, p = .64). Our results are discordant with previous findings indicating cognitive impairment following chemotherapy and suggest that TC patients do not need to fear long-term cognitive consequences following chemotherapy.

Modulation of medial temporal lobe activity in epilepsy patients with hippocampal sclerosis during verbal working memory

Abstract It has been traditionally assumed that medial temporal lobe (MTL) is not required for working memory (WM). However, animal lesion and electrophysiological studies and human neuropsychological and neuroimaging studies have provided increasing evidences of a critical involvement of MTL in WM. Based on previous findings, the central aim of this study was to investigate the contribution of the MTL to verbal WM encoding. Here, we used magnetoencephalography (MEG) to compare the patterns of MTL activation of 9 epilepsy patients suffering from left hippocampal sclerosis with those of 10 healthy matched controls while they performed a verbal WM task. MEG recordings allow detailed tracking of the time course of MTL activation. We observed impaired WM performance associated with changes in the dynamics of MTL activity in epilepsy patients. Specifically, whereas patients showed decreased activity in damaged MTL, activity in the contralateral MTL was enhanced, an effect that became significant in the 600- to 700-ms interval after stimulus presentation. These findings strongly support the crucial contribution of MTL to verbal WM encoding and provide compelling evidence for the proposal that MTL contributes to both episodic memory and WM. Whether this pattern is signaling reorganization or a normal use of a damaged structure is discussed. (JINS, 2009, 15, 536–546.)
Anosognosia in Alzheimer’s disease: The role of impairment levels in assessment of insight across domains

Abstract Impaired insight for deficits (anosognosia) is common in Alzheimer’s disease (AD). However, it has not yet been determined clearly (a) whether different methods for assessing insight are comparable, and (b) whether anosognosia affects different domains to different degrees (domain-specificity). Impaired insight was investigated in 32 patients with AD, who were each accompanied by a caregiver. Anosognosia was assessed by a global clinical rating, questionnaire discrepancies (patient vs. caregiver) covering different domains, and performance discrepancies (self-assessment vs. performance) based on four neuropsychological tests which were compared with those of a healthy control sample. The results of clinical rating and questionnaire discrepancies were closely correlated, but performance discrepancies showed no association with the other methods. Anosognosia was present in the majority of the sample, and occurred across domains. The domains corresponding to core deficits in AD (recent memory, activities of daily living) appeared especially prone to anosognosia. However, results do not suggest that anosognosia itself is domain-specific. Rather, it appears that insight may be invariant, while differences in patient-caregiver discrepancies arise largely from different degrees of deficit across domains. (JINS, 2010, 16, 463–473.)
Prediction of driving ability with neuropsychological tests: Demographic adjustments diminish accuracy

Abstract Demographically adjusted norms generally enhance accuracy of inferences based on neuropsychological assessment. However, we hypothesized that demographic corrections diminish predictive accuracy for real-world activities with absolute cognitive demands. Driving ability was assessed with a 45-minute drive along a standardized on-road route in participants aged 65+ (24 healthy elderly, 26 probable Alzheimer’s disease, 33 Parkinson’s disease). Neuropsychological measures included: Trail-Making A and B, Complex Figure, Benton Visual Retention, and Block Design tests. A multiple regression model with raw neuropsychological scores was significantly predictive of driving errors (R2 = .199, p = .005); a model with demographically adjusted scores was not (R2 = .113, p = .107). Raw scores were more highly correlated with driving errors than were adjusted scores for each neuropsychological measure, and among healthy elderly and Parkinson’s patients. When predicting real-world activities that depend on absolute levels of cognitive abilities regardless of demographic considerations, predictive accuracy is diminished by demographic corrections.

Cognitive reserve moderates decline in information processing speed in multiple sclerosis patients

Abstract Cognitive reserve is widely recognized as a moderator of cognitive decline in patients with senile dementias such as Alzheimer’s disease. The same effect may occur in multiple sclerosis (MS), an immunologic disorder affecting the central nervous system. While MS is traditionally considered an inflammatory, white matter disease, degeneration of gray matter is increasingly recognized as the primary contributor to progressive cognitive decline. Our aim was to determine if individual differences in estimated cognitive reserve protect against the progression of cognitive dysfunction in MS. Ninety-one patients assessed twice roughly 5 years apart were identified retrospectively. Cognitive testing emphasized mental processing speed. Cognitive reserve was estimated by years of education and by performance on the North American Adult Reading Test (NAART). After controlling for baseline characteristics, both years of education (p = .013) and NAART scores (p = .049) significantly improved regression models predicting cognitive decline. Symbol Digit Modalities Test (SDMT) performance showed no significant change in patients with > 14 years of education, whereas it declined significantly in patients with ≤ 14 years of education. We conclude that greater cognitive reserve as indexed by either higher premorbid intelligence or more years of education protects against the progression of cognitive dysfunction in MS.

Usefulness of ultrasound contrast media for cardiac output measurement with echocardiography

Abstract : The purpose of this study was to determine if contrast media would enhance visualization of the endocardiumfor assessment of left ventricle (LV) function. In addition, differences between pre- and post-contrast evaluation forthe cardiac output measurements including the modified Simpson’s method and automated contour tracking (ACT)method were examined. Ten clinically healthy adult beagle dogs (three males and seven females) between 2~3 yearsold and weighing 6.6~10.8 kg were used. Echocardiographic examinations were performed to compare pre- and post-contrast LV endocardium visualization using a segmental scoring method. Two different methods for measuring cardiacoutput were also compared. LV visualization was significantly enhanced in post-contrast echocardiography (p < 0.01). Significant differences between pre- and post-contrast measurements for the modified Simpson’s method (p < 0.05)were also observed. No significant difference was found for the ACT method. Contrast echocardiography provides betterLV chamber opacification and significantly improves wall segment visualization. Furthermore, contrast echocardiographyfor measuring cardiac output is helpful for the modified Simpson’s method.Keywords : cardiac output, contrast echocardiography, dog, segmental scoring,
A hierarchic 3D finite element for laminated composites

In this paper a new 3D multilayer element is presented for analysis of thick‐walled laminated composites. This element uses two steps to calculate the full stress tensor. In the first step the in‐plane stresses are computed from the material law using a displacement approximation, and then the transverse stresses are calculated from the 3D equilibrium equations. Since the 3D equilibrium equations require high‐order interpolation functions, a hierarchic interpolation of displacements is used. The new element is compared with existing ones, e.g. from MSC.MARC.

Evaluation of a community-based tobacco control intervention in five remote north Queensland Indigenous communities

This study aimed to assess the impact of a complex community-based tobacco control program in eight remote north Queensland Indigenous communities with high rates of tobacco use. A community-based tobacco intervention trial was conducted over one year in five intervention sites and three control sites in far north Queensland with predominantly Aboriginal and Torres Strait Islander populations. The intervention was composed of six components: a school-based education program ‘Smokin’ No Way’, ‘SmokeCheck’ tobacco brief intervention training for health workers, assistance to develop workplace smoke-free policies, an Event Support Program, ‘Smoke Rings’ support group and enforcement of tobacco sales legislation. Household surveys of self-reported tobacco use were conducted at baseline and one year after the interventions, along with interviews with key individuals and organisations, to assess intervention implementation. It was found that there was a modest effect on self-reported daily tobacco use and mean number of cigarettes smoked weekly after 12 months in intervention communities. There were non-significant declines in self-reported smoking and mean cigarettes smoked per week in aggregated control communities. Independent evaluation of fidelity of implementation found major shortcomings in actual program delivery. To enhance success of future interventions, fidelity of implementation should be ensured and a longer implementation period utilised.
Processing Speed Mediates Executive Function Difficulties in Very Preterm Children in Middle Childhood

Abstract Executive function and attention difficulties are reported in very preterm (VPT) children at school entry, but it is unclear if these remain at later ages and/or if these difficulties are mediated by more basic functions, such as processing speed. Processing speed has been shown to underlie academic and behavioral problems in VPT children in middle childhood (Mulder, Pitchford, & Marlow, 2010, 2011), so may also underpin executive function and attention difficulties. We investigated this by comparing VPT (gestational age <31 weeks; N = 56) to term children (N = 22) aged 9–10 years on a comprehensive battery of executive function and attention tasks from the Test of Everyday Attention for Children (Manly, Robertson, Anderson, & Nimmo-Smith, 1999) and NEPSY (Korkman, Kirk, & Kemp, 1998). Selective and sustained attention, inhibition, working memory, shifting, verbal fluency, planning, and processing speed were examined. Group differences favoring term children were shown on most executive function tasks (i.e., inhibition, working memory, verbal fluency, and shifting), all of which were mediated by slow processing speed in the VPT group, except response inhibition. Seemingly, processing speed is an important determinant underpinning many neuropsychological deficits seen in VPT children in middle childhood. (JINS, 2011, 17, 445–454)
Differential Contribution of Cognitive and Psychomotor Functions to the Age-Related Slowing of Speech Production

Abstract Healthy elderly adults are slower to initiate and produce speech. However, the sources of the slowing remain poorly understood. The present study evaluates to which extent psychomotor and cognitive changes influence age-related slowing in speech generation. Four verbal tasks varying in degree of difficulty and cognitive demands were used to evaluate 30 young and 30 healthy elderly. Speed of word production was measured by reaction times and pronunciation durations. Stroop test and Digits backwards were used as cognitive predictors while the Purdue Pegboard and Finger Tapping were used as psychomotor predictors. The relative contribution of cognitive and psychomotor functioning was evaluated by hierarchical regression analyses and based on the processing speed hypothesis. Results showed that Vocabulary and psychomotor execution significantly explained a portion of the variance in RTs depending on type of verbal task. These variables explained 36% of the total variance in reading, 26% in naming, 31% in phonemic fluency and 47% in semantic fluency. Also, Vocabulary and psychomotor functions strongly predicted pronunciation speed. Conversely, tests related to executive functions and working memory were not significant predictors. These data demonstrate the importance of the interplay between Vocabulary and psychomotor decline on speed of language production among healthy elderly adults. (JINS, 2011, 17, 807–821)
Effect of Literacy and Education on the Visuoconstructional Ability of Non-demented Elderly Individuals

Abstract Learning to read and to write influences not only verbal skills but also global cognitive performance. Our study aimed to compare the visuoconstructional abilities of elderly illiterates with those of elderly literates. A total of 125 healthy subjects over 65 years old were recruited. Korean version of Mini-Mental State Examination (K-MMSE) and the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog) constructional praxis examination were used. We divided subjects into three groups (educated literate n = 53, uneducated literate n = 36 and uneducated illiterate n = 36). Interlocking pentagons drawing, a part of the K-MMSE, was scored using the 6-point hierarchical scale. The uneducated-illiterate group obtained significantly lower scores than did the other two groups. Scores on the ADAS-cog constructional praxis test were highest in the educated-literate group and those in the uneducated-illiterate group obtained the lowest scores. We demonstrated that illiteracy influences not only language performance but also visuoconstructional functioning. (JINS, 2011, 17, 934–939)
A Prediction Model for the Presence of Axillary Lymph Node Involvement in Women with Invasive Breast Cancer: A Focus on Older Women

Axillary lymph node (ALN) status at diagnosis is the most powerful prognostic indicator for patients with breast cancer. Our aim is to examine the contribution of variables that lead to ALN metastases in a large dataset with a high proportion of patients greater than 70 years old. Using the data from two multicenter prospective studies, a retrospective review was performed on 2,812 patients diagnosed with clinically node‐negative invasive breast cancer from 1996 to 2005 and who underwent ALN sampling. Univariate and multivariate logistic regression were used to identify variables that were strongly associated with axillary metastases, and an equation was developed to estimate risk of ALN metastases. Of the 2,812 patients with invasive breast cancer, 18% had ALN metastases at diagnosis. Based on univariate analysis, tumor size, lymphovascular invasion (LVI), tumor grade, age at diagnosis, menopausal status, race, tumor location, tumor type, and estrogen and progesterone receptor status were statistically significant. The relationship between age and involvement of axillary metastases was nonlinear. In multivariate analysis, LVI, tumor size and menopausal status were the most significant factors associated with ALN metastases. Age, however, was not a significant contributing factor for axillary metastases. Tumor size, LVI, and menopausal status are strongly associated with ALN metastases. We believe that age may have been a strong factor in previous analyses because there was not an adequate representation of women in older age groups and because of the violation of the assumption of linearity in their multivariate analyses.
