    Genes and early-life adversity (ELA) interactively increase the risk of developing major depressive disorder (MDD). A recent genome-wide association study suggests that the minor T-allele of single-nucleotide polymorphisms in the bicaudal C homolog 1 gene (BICC1) has a protective role against MDD. The aims of the study were to investigate whether the minor T-allele of BICC1 is protective against hippocampal structural brain changes, whether it is associated with increased functional brain activity in the emotion regulation system, and how ELA would modify this association. Forty-four patients with MDD and 44 healthy controls were investigated using structural magnetic resonance imaging (MRI) and functional MRI with an emotion inhibition task. Analysis of a single-nucleotide polymorphism in the BICC1-1 (rs999845) gene was performed. Right hippocampal bodies of patients and controls without a history of ELA and who carry the protective T-allele of BICC1 were significantly larger compared with those participants homozygous for the major C-allele of BICC1. However, MDD patients with ELA, who carry the T-allele, had smaller hippocampal head volumes compared with MDD patients without ELA. FMRI showed that patients and controls carrying the protective T-allele of BICC1 activate the emotion regulation system significantly more compared with those participants homozygous for the major C-allele (pELA.

    Genetic defects in autosomal-dominant polycystic kidney disease (ADPKD) promote cystic growth of renal tubules,at least in part by stimulating the accumulation of cAMP.How renal cAMP levels are regulated is incompletely understood.We show that cAMP and the expression of its synthetic enzyme adenylate cyclase-6 (AC6) are up-regulated in cystic kidneys of Bicc1-/-knockout mice.Bicc1,a protein comprising three K homology (KH) domains and a sterile alpha motif (SAM),is expressed in proximal tubules.The KH domains independently bind AC6 mRNA and recruit the miR-125a from Dicer,whereas the SAM domain enables silencing by Argonaute and TNRC6A/GW182.Bicc1 similarly induces silencing of the protein kinase inhibitor PKlα by miR-27a.Thus,Bicc1 is needed on these target mRNAs for silencing by specific miRNAs.The repression of AC6 by Bicc1 might explain why cysts in ADPKD patients preferentially arise from distal tubules.

    2017-02-03

    Cerebrovascular disease typically manifests with stroke, cognitive impairment, or both. Vascular cognitive impairment refers to all forms of cognitive disorder associated with cerebrovascular disease, regardless of the specific mechanisms involved. It encompasses the full range of cognitive deficits from mild cognitive impairment to dementia. In principle, any of the multiple causes of clinical stroke can cause vascular cognitive impairment. Recent work further highlights a role of microinfarcts, microhemorrhages, strategic white matter tracts, loss of microstructural tissue integrity, and secondary neurodegeneration. Vascular brain injury results in loss of structural and functional connectivity and, hence, compromise of functional networks within the brain. Vascular cognitive impairment is common both after stroke and in stroke-free individuals presenting to dementia clinics, and vascular pathology frequently coexists with neurodegenerative pathology, resulting in mixed forms of mild cognitive impairment or dementia. Vascular dementia is now recognized as the second most common form of dementia after Alzheimer's disease, and there is increasing awareness that targeting vascular risk may help to prevent dementia, even of the Alzheimer type. Recent advances in neuroimaging, neuropathology, epidemiology, and genetics have led to a deeper understanding of how vascular disease affects cognition. These new findings provide an opportunity for the present reappraisal of vascular cognitive impairment. We further briefly address current therapeutic concepts.

    Social communication or pragmatic impairments are characterized and illustrated as involving inappropriate or ineffective use of language and gesture in social contexts. Three clinical vignettes illustrate different pragmatic impairments and the wealth of diagnostic information that can be garnered from observation of a child's social communication behavior. Definitions of, and developmental milestones in, domains of pragmatic competence are provided. Several screening instruments are suggested for use in assessing pragmatic competence within the time-frame of a pediatric examination. Frequent comorbid psychiatric conditions are described and a sample of current neurobiologic research is briefly summarized.

    Full Text Available Mild cognitive impairment (MCI is a syndrome that spans the area between normal ageing and dementia. It is classified into amnestic and non-amnestic types, both with two subtypes: single domain and multiple domains. Prevalence of MCI depends on criteria and population and can vary from 0.1 to 42% persons of older age. In contrast to dementia, cognitive deterioration is less severe and activities of daily living are preserved. Most impaired higher cognitive functions in MCI are memory, executive functions, language, visuospatial functions, attention etc. Also there are depression, apathy or psychomotor agitation, and signs of psychosis. Aetiology of MCI is multiple, mostly neurodegenerative, vascular, psychiatric, internistic, neurological, traumatic and iatrogenic. Persons with amnestic MCI are at a higher risk of converting to Alzheimer's disease, while those with a single non-memory domain are at risk of developing frontotemporal dementia. Some MCI patients also progress to other dementia types, vascular among others. In contrast, some patients have a stationary course, some improve, while others even normalize. Every suspicion of MCI warrants a detailed clinical exploration to discover underlying aetiology, laboratory analyses, neuroimaging methods and some cases require a detailed neuropsychological assessment. At the present time there is no efficacious therapy for cognitive decline in MCI or the one that could postpone conversion to dementia. The treatment of curable causes, application of preventive measures and risk factor control are reasonable measures in the absence of specific therapy.

    Specific language impairment is one of the most common developmental disturbances in childhood. With the increase of the foreign language population group an increasing number of children assimilating several languages and causing concern in language development attend clinical examinations. Knowledge of factors underlying the specific language impairment and the specific impairment in general, special features of language development of those learning several languages, as well as the assessment and support of the linguistic skills of a multilingual child is essential. The risk of long-term problems and marginalization is high for children having specific language impairment.

    Vascular cognitive impairment and vascular dementia are composed of cognitive deficits resulted from a range of vascular lesions and pathologies, including both ischemic and hemorrhagic. However the contribution of spontaneous intracerebral hemorrhage presumed due to small vessel diseases on cognitive impairment is underestimated, in contrast to the numerous studies about the role of ischemic vascular disorders on cognition. In this review we summarize recent findings from clinical studies and appropriate basic science research to better elucidate the role and possible mechanisms of intracerebral hemorrhage in cognitive impairment and dementia.

    2002-01-01

    We report a 60-year-old right-handed Japanese man who showed an isolated persistent typing impairment without aphasia, agraphia, apraxia or any other neuropsychological deficit. We coined the term 'dystypia' for this peculiar neuropsychological manifestation. The symptom was caused by an infarction in the left frontal lobe involving the foot of the second frontal convolution and the frontal operculum. The patient's typing impairment was not attributable to a disturbance of the linguistic process, since he had no aphasia or agraphia. The impairment was not attributable to the impairment of the motor execution process either, since he had no apraxia. Thus, his typing impairment was deduced to be based on a disturbance of the intermediate process where the linguistic phonological information is converted into the corresponding performance. We hypothesized that there is a specific process for typing which branches from the motor programming process presented in neurolinguistic models. The foot of the left second frontal convolution and the operculum may play an important role in the manifestation of 'dystypia'.

    Objective The aim of this study was to assess the potential risk of gadobutrol-enhanced magnetic resonance imaging (MRI) in patients with moderate to severe renal impairment for the development of nephrogenic systemic fibrosis (NSF). Materials and Methods We performed a prospective, international, multicenter, open-label study in 55 centers. Patients with moderate to severe renal impairment scheduled for any gadobutrol-enhanced MRI were included. All patients received a single intravenous bolus injection of gadobutrol at a dose of 0.1 mmol/kg body weight. The primary target variable was the number of patients who develop NSF within a 2-year follow-up period. Results A total of 908 patients were enrolled, including 586 with moderate and 284 with severe renal impairment who are at highest risk for developing NSF. The mean time since renal disease diagnosis was 1.83 and 5.49 years in the moderate and severe renal impairment cohort, respectively. Overall, 184 patients (20.3%) underwent further contrast-enhanced MRI with other gadolinium-based contrast agents within the 2-year follow-up. No patient developed symptoms conclusive of NSF. Conclusions No safety concerns with gadobutrol in patients with moderate to severe renal impairment were identified. There were no NSF cases. PMID:27529464

    2004-12-01

    Full Text Available This article deals with different types of language impairment from the perspective of generative grammar. The paper focuses on syntactic deficiencies observed in aphasic and SLI (specific language impairment patients. We show that the observed ungrammatical structures do not appear in a random fashion but can be predicted by that theory of universal sentence structure which posits a strict hierarchy of its constituent parts. The article shows that while the hierarchically lower elements remain unaffected, the higher positions in the hierarchy show various degrees of syntactic impairment. The paper supports the implementation of recent developments in the field of generative grammar with the intention of encouraging further theoretical, experimental and therapeutic research in the field.

    Parkinson's disease (PD) is a progressive neurodegenerative disease primarily characterized by the hallmarks of motor symptoms, such as tremor, bradykinesia, rigidity, and postural instability. However, through clinical investigations in patients and experimental findings in animal models of Parkinson's disease for years, it is now well recognized that Parkinson's disease is more than just a motor-deficit disorder. The majority of Parkinson's disease patients suffer from nonmotor disabilities, for instance, cognitive impairment, autonomic dysfunction, sensory dysfunction, and sleep disorder. So far, anti-PD prescriptions and surgical treatments have been mainly focusing on motor dysfunctions, leaving cognitive impairment a marginal clinical field. Within the nonmotor symptoms, cognitive impairment is one of the most common and significant aspects of Parkinson's disease, and cognitive deficits such as dysexecutive syndrome and visuospatial disturbances could seriously affect the quality of life, reduce life expectancy, prolong the duration of hospitalization, and therefore increase burdens of caregiver and medical costs. In this review, we have done a retrospective study of the recent related researches on epidemiology, clinical manifestation and diagnosis, genetics, and potential treatment of cognitive deficits in Parkinson's disease, aiming to provide a summary of cognitive impairment in Parkinson's disease and make it easy for clinicians to tackle this challenging issue in their future practice.

    Full Text Available Cognitive impairment can emerge in the earliest phases of multiple sclerosis. It strongly impacts different aspects of Multiple Sclerosis (MS patients' lives, like employment, social relationships and the overall quality of life; thus, its on-time recognition and treatment is mandatory. This paper discusses issues, diagnostic methods and treatment options for cognitive dysfunctions in MS. This paper is a descriptive review of the related studies in the recent 10 years, performing a keyword search in the main databases4T. Cognitive impairment mostly involves aspects of information processing, memory and executive functioning in MS. Neuropsychological tests like MACFIMS and BRB-N are recommended for its assessment. Still, there is no fully efficient treatment for cognitive impairment. Researchers have shown some positive effects, using disease-modifying therapies and cognitive rehabilitation. Depression, pain, fatigue and other factors influencing cognitive functions must be paid attention to4T. Recognizing cognitive impairment as a major symptom for MS, makes studying this subject one of the priorities in dealing with the disease. Therefore, a consecutive research for identification and management of this part of quality of life in MS patients is obligatory4T.4T

  2. Relevance theory and pragmatic impairment.

    Leinonen, E; Kerbel, D

    1999-01-01

    This paper summarizes aspects of relevance theory that are useful for exploring impairment of pragmatic comprehension in children. It explores data from three children with pragmatic language difficulties within this framework. Relevance theory is seen to provide a means of explaining why, in a given context, a particular utterance is problematic. It thus enables one to move on from mere description of problematic behaviours towards their explanation. The theory provides a clearer delineation between the explicit and the implicit, and hence between semantics and pragmatics. This enables one to place certain difficulties more firmly within semantics and others within pragmatics. Relevance, and its maximization in communication, are squarely placed within human cognition, which suggests a close connection between pragmatic and cognitive (dis)functioning. Relevance theory thus emerges as a powerful tool in the exploration and understanding of pragmatic language difficulties in children and offers therapeutically valuable insight into the nature of interactions involving individuals with such impairments.

  5. Mandatory notification of impaired doctors.

    2014-12-01

    Mandatory reporting of impaired doctors is compulsory in Australasia. Australian Health Practitioner Regulation Agency guidelines for notification claim high benchmark though the Royal Australasian College of Surgeons and the Royal Australasian College of Physicians suggest they still obstruct doctors seeking help. Western Australia excludes mandatory reporting of practitioner-patients. This study examines reporting, consequences and international experiences with notification. Depressed doctors avoid diagnosis and treatment, fearing consequences, yet are more prone to marital problems, substance dependence and needing psychotherapy. South African research confirms isolation of impaired doctors and delayed seeking help with definable characteristics of those at risk. New Zealand data acknowledge: errors occur; questionable contribution from mandatory reporting; issues concerning competence assessment; favouring reporting to senior colleagues or self-intervention to compliance with mandatory reporting. UK found an anaesthetist guilty of professional misconduct for not reporting and sanctioned doctors regarding Harold Shipman. Australians are reluctant to report, fearing legalistic intrusion into care. Australian research confirmed definable characteristics for doctors with psychiatric illness or alcohol abuse. Exposure to legal medicine evokes personal disenchantment for doctors involved. Medicine poses barriers for impaired doctors. Spanish and UK doctors do not use general practitioners and may have suboptimal care. US and European doctors self-medicate using samples. US drug-dependent doctors also prescribe for spouses. Junior doctors are losing empathy with the profession. UK doctors favour private care, avoiding public scrutiny. NZ and Brazil created specific services for doctors, which appear effective. Mandatory reporting may be counterproductive requiring reappraisal.

    There is strong evidence that diabetes mellitus increases the risk of cognitive impairment and dementia. Insulin signaling dysregulation and small vessel disease in the base of diabetes may be important contributing factors in Alzheimer’s disease and vascular dementia pathogenesis, respectively. Optimal glycemic control in type 1 diabetes and identification of diabetic risk factors and prophylactic approach in type 2 diabetes are very important in the prevention of cognitive complications. In addition, hypoglycemic attacks in children and elderly should be avoided. Anti-diabetic medications especially Insulin may have a role in the management of cognitive dysfunction and dementia but further investigation is needed to validate these findings. PMID:27660698

  10. Cognitive Impairment in Heart Failure

    Directory of Open Access Journals (Sweden)

    Efthimios Dardiotis

    2012-01-01

    Full Text Available Cognitive impairment (CI is increasingly recognized as a common adverse consequence of heart failure (HF. Although the exact mechanisms remain unclear, microembolism, chronic or intermittent cerebral hypoperfusion, and/or impaired cerebral vessel reactivity that lead to cerebral hypoxia and ischemic brain damage seem to underlie the development of CI in HF. Cognitive decline in HF is characterized by deficits in one or more cognition domains, including attention, memory, executive function, and psychomotor speed. These deficits may affect patients’ decision-making capacity and interfere with their ability to comply with treatment requirements, recognize and self-manage disease worsening symptoms. CI may have fluctuations in severity over time, improve with effective HF treatment or progress to dementia. CI is independently associated with disability, mortality, and decreased quality of life of HF patients. It is essential therefore for health professionals in their routine evaluations of HF patients to become familiar with assessment of cognitive performance using standardized screening instruments. Future studies should focus on elucidating the mechanisms that underlie CI in HF and establishing preventive strategies and treatment approaches.

  11. Ego depletion impairs implicit learning.

    2014-01-01

    Implicit skill learning occurs incidentally and without conscious awareness of what is learned. However, the rate and effectiveness of learning may still be affected by decreased availability of central processing resources. Dual-task experiments have generally found impairments in implicit learning, however, these studies have also shown that certain characteristics of the secondary task (e.g., timing) can complicate the interpretation of these results. To avoid this problem, the current experiments used a novel method to impose resource constraints prior to engaging in skill learning. Ego depletion theory states that humans possess a limited store of cognitive resources that, when depleted, results in deficits in self-regulation and cognitive control. In a first experiment, we used a standard ego depletion manipulation prior to performance of the Serial Interception Sequence Learning (SISL) task. Depleted participants exhibited poorer test performance than did non-depleted controls, indicating that reducing available executive resources may adversely affect implicit sequence learning, expression of sequence knowledge, or both. In a second experiment, depletion was administered either prior to or after training. Participants who reported higher levels of depletion before or after training again showed less sequence-specific knowledge on the post-training assessment. However, the results did not allow for clear separation of ego depletion effects on learning versus subsequent sequence-specific performance. These results indicate that performance on an implicitly learned sequence can be impaired by a reduction in executive resources, in spite of learning taking place outside of awareness and without conscious intent.

    2015-06-01

    Because healthy physical and mental functioning depends on the ability to regulate emotions, it is important to identify moderators of such regulations. Whether mental fatigue, subsequent to the depletion of cognitive resources, impairs explicit emotion regulation to negative stimuli is currently unknown. This study explored this possibility. In a within-subject design over 2 separate sessions, healthy individuals performed easy (control session) or difficult (depletion session) cognitive tasks. Subsequently, they were presented with neutral and negative pictures, with instructions to either maintain or regulate (i.e., reduce) the emotions evoked by the pictures. Emotional reactivity was probed with the startle reflex. The negative pictures evoked a similar aversive state in the control and depletion sessions as measured by startle potentiation. However, subjects were able to down-regulate their aversive state only in the control session, not in the depletion session. These results indicate that mental fatigue following performance of cognitive tasks impairs emotion regulation without affecting emotional reactivity. These findings suggest that mental fatigue needs to be incorporated into models of emotion regulation.

    2005-01-01

    Full Text Available Introduction Establishing continuity of long bones in cases of impaired bone healing and pseudo-arthrosis is one of the most complex problems in orthopedics. Impaired bone healing The problem of impaired fracture healing is not new. As in other areas of human life, the roots of modern treatment of impaired bone healing lie in ancient medicine. A relatively high percentage of impaired bone healing, as well as unsatisfactory results of standard therapies of impaired bone healing and pseudoarthrosis demonstrate the actuality of this problem. This paper represents an attempt to pay respect to some of those who have dedicated their work to this problem in orthopedic surgery, and it is a historical review on impaired bone fracture healing. At the same time it should be an additional stimulus and challenge for orthopedic surgeons to further study impaired bone fracture healing, improve the existing and find new methods for their adequate treatment. Conclusion The authors are certain that the number of researchers throughout the world who have contributed to treatment modalities of impaired bone healing, is much higher, but not all are mentioned in this paper. However, it does not lessen their contributions to orthopedics.

    2013-05-01

    Full Text Available Impairment and revaluation are terms closely related to one another, with subtle differences. Revaluation and impairment both require the company to evaluate the assets for their fair value, and then take appropriate action in updating the accounting books. The major difference between the two is that a revaluation can be made upwards (to increase the value of the asset to market value or downwards (to ecrease the value. An impairment, on the other hand, only refers to one of the two, a fall in the market value which is then written down. The purpose of the paper is to establish what are the differences between revaluation and impairment of assets.

    Language alterations in Huntington's disease (HD) are reported, but their nature and correlation with other cognitive impairments are still under investigation. This study aimed to characterize the language disturbances in HD and to correlate them to motor and cognitive aspects of the disease. We studied 23 HD patients and 23 controls, matched for age and schooling, using the Boston Diagnostic Aphasia Examination, Boston Naming Test, the Token Test, Animal fluency, Action fluency, FAS-COWA, the Symbol Digit Modalities Test, the Stroop Test and the Hooper Visual Organization Test (HVOT). HD patients performed poorer in verbal fluency (poral comprehension (preading comprehension (p=0.034) and narrative writing (p<0.0001). There was a moderate correlation between the Expressive Component and Language Competency Indexes and the HVOT (r=0.519, p=0.011 and r=0.450, p=0.031, respectively). Language alterations in HD seem to reflect a derangement in both frontostriatal and frontotemporal regions.

  18. Cognitive impairment in Wilson's disease

    Directory of Open Access Journals (Sweden)

    Norberto Anizio Ferreira Frota

    Full Text Available Abstract Wilson's disease (WD or hepatolenticular degeneration is a rare, genetic and systemic disease, caused by a deficit in the metabolism of copper, leading to its accumulation in different organs, mainly the liver, followed by the central nervous system, especially the basal ganglia. When symptoms begin between the second and third decades of life, approximately 50% of the patients show neurological symptoms. Although dystonia and dysarthria are the most common neurological signs, cognitive changes have been reported since the first cases were described in 1912. Memory change is one of the most common impairments, but other cognitive changes have been reported, including dementia in untreated cases. In this article we review the cognitive changes in WD patients and the occurrence of dementia.

    2015-12-01

    Parkinson's disease is the second most frequent neurodegenerative disorder. There is significantly elevated risk of cognitive decline and associated neuropsychiatric symptoms. Dementia may develop insidiously several years after manifestation of Parkinson motor symptoms (dementia associated with Parkinson's disease; Parkinson's disease dementia) or in close temporal relationship (within one year) after onset of motor symptoms (Dementia with Lewy bodies). There are clinical, pathophysiological and therapeutic similarities between these two conditions. Men are more frequently affected than women. Risk factor or indicators are advanced age at disease onset, disease duration, rigidity, akinesia and posture and gait impairment and falls as opposed to tremor dominance, and associated neuropsychiatric symptoms (depression, apathy, hallucinosis, delirium). Dementia is treatable with cholinesterase inhibitors (rivastigmine, donepezil), memantine, and adjustment of the pharmacological regimen of parkinsonian motor symptoms. Concomitant autonomic nervous system symptoms and neuropsychiatric complications warrant early clinical awareness and are accessible to pharmacological therapy.

    Full Text Available The objectives of this study were to characterize and clarify the relationships between the various cognitive domains affected in COPD patients and the disease itself, as well as to determine the prevalence of impairment in the various cognitive domains in such patients. To that end, we performed a systematic review using the following databases: PubMed, Scopus, and ScienceDirect. We included articles that provided information on cognitive impairment in COPD patients. The review of the findings of the articles showed a significant relationship between COPD and cognitive impairment. The most widely studied cognitive domains are memory and attention. Verbal memory and learning constitute the second most commonly impaired cognitive domain in patients with COPD. The prevalence of impairment in visuospatial memory and intermediate visual memory is 26.9% and 19.2%, respectively. We found that cognitive impairment is associated with the profile of COPD severity and its comorbidities. The articles reviewed demonstrated that there is considerable impairment of the cognitive domains memory and attention in patients with COPD. Future studies should address impairments in different cognitive domains according to the disease stage in patients with COPD.

    2011-01-01

    Full Text Available Cognitive impairments (CIs are a highly common type of neurological disorders particularly in elderly patients. Choice of a therapeutic strategy for CI is determined by the etiology of abnormalities and their degree. Measures to prevent CI progression and dementia: adequate treatment of existing cardiovascular diseases, prevention of stroke, balanced nutrition, moderate physical and intellectual exercises, and combatting overweight and low activity are of basic value in treating mild and moderate CIs. According to the data of a number of investigations, the above measures reduce the risk of dementia, including in the genetically predisposed. Pharmacotherapy for mild and moderate CIs generally comprises vasoactive, neurometabolic, and noradrenergic agents. The indication for the use of memantine and/or acetylcholinergic agents, i.e. basic therapy for the most common forms of dementia (Alzheimer's disease, Lewy body dementia, vascular, and mixed dementia, hepatic colics is severe CIs. The long-term use of memantine and/or acetylcholinergic agents alleviates the cognitive and behavioral symptoms of dementia, enhances self-dependence in patients, and prolongs their active lifetime.

  16. Relative clause reading in hearing impairment: Different profiles of syntactic impairment

    Directory of Open Access Journals (Sweden)

    Ronit eSzterman

    2014-11-01

    Full Text Available Children with hearing impairment show difficulties in sentences derived by Wh-movement, such as relative clauses and Wh-questions. This study examines the nature of this deficit in 48 hearing impaired children aged 9-12 years and 38 hearing controls. The task involved reading aloud and paraphrasing of object relatives that include a noun-verb heterophonic homograph. The correct pronunciation of the homograph in these sentences depended upon the correct construction of the syntactic structure of the sentence. An analysis of the reading and paraphrasing of each participant exposed two different patterns of syntactic impairment. Some hearing-impaired children paraphrased the object relatives incorrectly but could still read the homograph, indicating impaired assignment of thematic roles alongside good syntactic structure building; other hearing-impaired children could neither read the homograph nor paraphrase the sentence, indicating a structural deficit in the syntactic tree. Further testing of these children confirmed the different impairments: some are impaired only in Wh-movement, whereas others have CP impairment. The syntactic impairment correlated with whether or not a hearing device was fitted by the age of one year, but not with the type of hearing device or the depth of hearing loss: children who had a hearing device fitted during the first year of life had better syntactic abilities than children whose hearing devices were fitted later.

    DEFF Research Database (Denmark)

    Andersson, A-M; Jørgensen, N; Frydelund-Larsen, L

    2004-01-01

    To investigate whether an impaired Leydig cell function is present in severely oligospermic men, serum testosterone (T), LH, estradiol (E(2)), and SHBG levels in 357 idiopathic infertile men were compared with levels in 318 proven fertile men. In addition, the T/LH ratio, E(2)/T ratio...... of the fertile levels.Thus, the group of infertile men showed significant signs of impaired Leydig cell function in parallel to their impaired spermatogenesis. The association of decreased spermatogenesis and impaired Leydig cell function might reflect a disturbed paracrine communication between the seminiferous......, and calculated free T index (cFT) were compared between the two groups.A shift toward lower serum T levels, cFT, and T/LH ratio and higher serum LH, E(2), and E(2)/T levels was observed in the group of infertile men. On average, the infertile men had 18, 26, and 34% lower serum T, cFT, and T/LH levels...

The authors conducted a comparative analysis of communication difficulties in typically developed teenagers aged 12-13 years (n = 100 and the problems faced by their peers with visual (n = 30, auditory (n = 30, speech (n = 25 and motor (n = 15 impairments. Actual communication difficulties in teenagers were studied in two ways: the subjective component of impaired communication was registered through a content analysis of a sentence completion test and the objective manifestations of impaired communication were identified through expert evaluation of children’s communicative behavior (educators and psychologists who had been in close contact with the teenagers acted as experts. First, the authors identified typical standard communication problems that were characteristic of teenagers aged 12-13 years, that is, problems with aggression, tolerance, the ability to admit wrongdoing and make concessions, empathy, self-control, self-analysis and self-expression in communication. Second, typical communication difficulties characteristic of physically impaired children were revealed: failure to understand meaning; feelings of awkwardness and shame of oneself; expectations of a negative attitude toward oneself; gelotophobia; and manifestations of despotism, petulance and egotism as defensive reactions in situations of impaired communication. Third, the authors described specific communication difficulties in teenagers with auditory, visual, speech and motor impairments.

    Alveolar hypoxia causes pulmonary vasoconstriction; we investigated whether hypoxia could also impair pulmonary vasodilation. We found in the isolated perfused rat lung a delay in vasodilation following agonist-induced vasoconstriction. The delay was not due to erythrocyte or plasma factors, or to alterations in base-line lung perfusion pressure. Pretreating lungs with arachidonic acid abolished hypoxic vasoconstriction, but did not influence the hypoxia-induced impairment of vasodilation aft...

  5. Difficulties in Parenting Hearing-Impaired Children

    2010-06-01

    Full Text Available Background and Aim: Despite the abundance of literature about deaf children, few works specifically address the concept and practice of difficulties in parenting hearing-impaired children. The first interactions of the child are with his parents, and parents have the most important role in child improvements during early intervention programs. The main purpose of this paper was to investigate different aspects of parenting hearing-impaired children.Methods: In this article, we reviewed all aspects of parenting hearing-impaired children in papers from 1984-2009 in Medline, Scopus and Proquest and relative textbooks. The semi-professional role of parents of hearing-impaired children make them feel under excessive stress and this usually affects their other roles as fathers and mothers. Many factors including child age, type of hearing loss and parents’ individual characteristics may influence the impact of child’s hearing loss on parents.Conclusion: Parenting a hearing-impaired child is both similar and different to parenting any other child. Where there are differences, there are usually challenges too. Taking support and advice from professionals and other parents are necessary and invaluable for parents of hearing-impaired children.

    2012-10-01

    Full Text Available Background and Aim: The somatosensory system is one of the most effective systems in balance control. It consists of peripheral and central components. Knowing the role of these components in balance control assists the developing of effective rehabilitation protocols. In some diseases peripheral components and in others central components are impaired. This paper reviews the effect of impairment of peripheral and central components of the somatosensory system on balance control.Methods: In this study publication about somatosensory impairments from 1983 through 2011 in PubMed, Scopus, ProQuest, Google Scholar, Iran Medex, Iran Doc and Magiran were reviewed. Medical subject headings terms and keywords related to balance, somatosensory, somatosensory loss, and sensory integration/processing were used to perform the searches.Conclusion: Somatosensory impairments either with peripheral or central origin, can cause problems in balance control. However, these problems are not considered in some patients. In these impairments, balance training is recommended to be used alongside other routine treatments in the patients' rehabilitation programs.

    The elderly population is increasing worldwide and it has been suggested that senior citizens will continue to constitute the bulk of the population in many countries. Nutritional status of senior citizens are adversely affected by their frailty, chronic condition and declining cognitive functioning. Conversely, malnourished elderly further deteriorate their frailty, chronic disease and cognitive functioning. The aim of this review article is to recognize the importance of nutritional assessment of elderly population particularly those with cognitive impairment. First part is to highlight characteristic cognitive impairment among senior citizens and the second one highlight t he background in which malnutrition is a factor that leads to increased risk of morbidity and mortality in the elderly. This review also highlight salgorithms for safeguarding nutritional status among senior citizen and focuses on importance of nutritional screening, assessment and early intervention for safeguarding further deterioration of elderly who are likely to prone to cognitive impairment.

    2013-05-01

    Full Text Available Chronic fatigue syndrome (CFS is characterized by fatigue, sleep dysfunction, and cognitive deficits (Fukuda et al., 1994. Research surrounding cognitive functioning among patients with CFS has found difficulty with memory, attention, and information processing. A similar disorder, postural tachycardia syndrome (POTS, is characterized by increased heart rate, fatigue, and mental cloudiness (Raj et al., 2009. Potential implications of cognitive deficits for patients with CFS and/or POTS are discussed, including difficulties with school and/or employment. A few biological theories (i.e., kindling, impairments in the central nervous system, and difficulty with blood flow have emerged as potential explanations for the cognitive deficits reported in both CFS and POTS Future research should continue to examine possible explanations for cognitive impairments in CFS and POTS, and ultimately use this information to try and reduce cognitive impairments for these patients.

    Olsen, Kirsty; Taylor, John-Paul; Thomas, Alan

    2014-06-01

    Driving is an important aspect of daily living and for many older people provides autonomy and psycho-social benefits. Cognitive impairment has been found to impact driving skills at the level of dementia, however, uncertainty remains around the impact of a diagnosis of the pre-dementia condition mild cognitive impairment. Current official guidelines are unclear, and assessment of fitness to drive can be problematical. This editorial examines current official guidance available to the clinician and problems with existing assessment as well as the current position of research specifically into MCI and driving, and considers future direction for research in this field.

    2013-01-01

    There are around 285 million visually impaired people worldwide, and around 370,000 people are registered as blind or partially sighted in the UK. Ongoing advances in information technology (IT) are increasing the scope for IT-based mobile assistive technologies to facilitate the independence, safety, and improved quality of life of the visually impaired. Research is being directed at making mobile phones and other handheld devices accessible via our haptic (touch) and audio sensory channels. We review research and innovation within the field of mobile assistive technology for the visually impaired and, in so doing, highlight the need for successful collaboration between clinical expertise, computer science, and domain users to realize fully the potential benefits of such technologies. We initially reflect on research that has been conducted to make mobile phones more accessible to people with vision loss. We then discuss innovative assistive applications designed for the visually impaired that are either delivered via mainstream devices and can be used while in motion (e.g., mobile phones) or are embedded within an environment that may be in motion (e.g., public transport) or within which the user may be in motion (e.g., smart homes).

    Diabetic patients are known to be more susceptible to atherosclerosis and its associated cardiovascular complications. However, the effects of hyperglycemia on atherosclerosis regression remain unclear. We hypothesized that hyperglycemia impairs atherosclerosis regression by modulating the biological function of lesional macrophages. HypoE (Apoe(h/h)Mx1-Cre) mice express low levels of apolipoprotein E (apoE) and develop atherosclerosis when fed a high-fat diet. Atherosclerosis regression occurs in these mice upon plasma lipid lowering induced by a change in diet and the restoration of apoE expression. We examined the morphological characteristics of regressed lesions and assessed the biological function of lesional macrophages isolated with laser-capture microdissection in euglycemic and hyperglycemic HypoE mice. Hyperglycemia induced by streptozotocin treatment impaired lesion size reduction (36% versus 14%) and lipid loss (38% versus 26%) after the reversal of hyperlipidemia. However, decreases in lesional macrophage content and remodeling in both groups of mice were similar. Gene expression analysis revealed that hyperglycemia impaired cholesterol transport by modulating ATP-binding cassette A1, ATP-binding cassette G1, scavenger receptor class B family member (CD36), scavenger receptor class B1, and wound healing pathways in lesional macrophages during atherosclerosis regression. Hyperglycemia impairs both reduction in size and loss of lipids from atherosclerotic lesions upon plasma lipid lowering without significantly affecting the remodeling of the vascular wall.

    Speech correlates of alcohol/drug impairment and its neurological basis is presented with suggestion for further research in impairment from poly drug/medicine/inhalent/chew use/abuse, and prediagnosis of many neuro- and endocrin-related disorders. Nerve cells all over the body detect chemical entry by smoking, injection, drinking, chewing, or skin absorption, and transmit neurosignals to their corresponding cerebral subsystems, which in turn affect speech centers-Broca's and Wernick's area, and motor cortex. For instance, gustatory cells in the mouth, cranial and spinal nerve cells in the skin, and cilia/olfactory neurons in the nose are the intake sensing nerve cells. Alcohol depression, and brain cell damage were detected from telephone speech using IMPAIRLYZER-TM, and the results of these studies were presented at 1996 ASA meeting in Indianapolis, and 2001 German Acoustical Society-DEGA conference in Hamburg, Germany respectively. Speech based chemical Impairment measure results were presented at the 2001 meeting of ASA in Chicago.

    Full Text Available The purpose of the study was to identify changes in cognitive abilities that affect patients with relapsing remitting form of multiple sclerosis (MS and to find out which instrument manifests them best. The performance of MS patients was compared to a matched group of healthy people using three neuropsychological tests: Wisconsin card sorting test (WCST, Stroop color and word test and Trail making test (TMT part B. Results on all three tests indicate general cognitive impairments in the group of patients. Compared to the group of healthy people patients with MS exhibited impaired ability of abstract reasoning (WCST, impaired cognitive flexibility and less resistance to irrelevant stimuli (Stroop color and word test, slowed information processing and impaired ability of shifting attention from one symbol to another (TMT. The largest differences between groups occured in Stroop color and word test as well as in TMT. The estimation of cognitive abilities of MS patients is of high importance and sistematicaly observing of changes in those abilities should be considered.

    2016-09-01

    Flexibility of associative learning can be revealed by establishing and then reversing cue-outcome discriminations. Here, we used functional MRI to examine whether neurobehavioral correlates of reversal-learning are impaired in White and Asian volunteers when initial learning involves fear-conditioning to a racial out-group. For one group, the picture of a Black male was initially paired with shock (threat) and a White male was unpaired (safe). For another group, the White male was a threat and the Black male was safe. These associations reversed midway through the task. Both groups initially discriminated threat from safety, as expressed through skin conductance responses (SCR) and activity in the insula, thalamus, midbrain and striatum. After reversal, the group initially conditioned to a Black male exhibited impaired reversal of SCRs to the new threat stimulus (White male), and impaired reversals in the striatum, anterior cingulate cortex, midbrain and thalamus. In contrast, the group initially conditioned to a White male showed successful reversal of SCRs and successful reversal in these brain regions toward the new threat. These findings provide new evidence that an aversive experience with a racial out-group member impairs the ability to flexibly and appropriately adjust fear expression towards a new threat in the environment.

    2005-01-01

    We describe a patient, HE, who was left with a remarkably selective deficit in intermediate vision following an infarct in the right occipito-temporal region. Thus, HE was able to group elements by colour and proximity but impaired in grouping based on similarity in shape. This finding supports...... the notion that grouping may be divided into two general steps: (i) element clustering and (ii) shape configuration, with the latter operation being impaired in HE. As opposed to previous cases with shape integration deficits, HE was able to name objects accurately. Initially, this might suggest that shape...... integration is not a prerequisite for normal object naming. However, on more demanding tests of visual object recognition, HE's performance deteriorated, with her performance being inversely related to the demand placed on integration of local elements into more elaborate shape descriptions. From this we...

  5. Impaired inhibitory control in recreational cocaine users.

    Directory of Open Access Journals (Sweden)

    Lorenza S Colzato

    Full Text Available Chronic use of cocaine is associated with impairment in response inhibition but it is an open question whether and to which degree findings from chronic users generalize to the upcoming type of recreational users. This study compared the ability to inhibit and execute behavioral responses in adult recreational users and in a cocaine-free-matched sample controlled for age, race, gender distribution, level of intelligence, and alcohol consumption. Response inhibition and response execution were measured by a stop-signal paradigm. Results show that users and non users are comparable in terms of response execution but users need significantly more time to inhibit responses to stop-signals than non users. Interestingly, the magnitude of the inhibitory deficit was positively correlated with the individuals lifetime cocaine exposure suggesting that the magnitude of the impairment is proportional to the degree of cocaine consumed.

    Demographic changes highlight the need to address disabilities associated with the costly morbidities of old age, such as dementia. Memory impairment associated with dementia represents a significant challenge for many older people. Difficulties occur in carrying out activities in their entirety or in commencing them at all. Technology has the potential to help individuals overcome the barriers created by cognitive disability in terms of performing activities of daily living and therefore help to maintain independence and enhance quality of life (Czaja, 2005). This literature review examines the current reported research, which employs electronic reminding technology to support individuals with cognitive impairment. These devices range from everyday technologies, such as phones, to sophisticated interactive devices with specifically designed software. A summary of the current evidence base is presented and recommendations for future practice are made.

    We describe a 59-year-old woman, M.T., with a progressive language impairment and neuroimaging findings of decreased perfusion (SPECT) and focal atrophy (MRI) in the left temporal region. The most prominent feature of her cognitive profile was a profound and progressive impairment in naming. In spite of this, she performed normally on tests of semantic processing and phonological output. Her spontaneous speech was fluent with preserved syntax and articulation but with notable word-finding problems. All other cognitive abilities were relatively stable and intact. These features are not typical of either fluent or non-fluent forms of neurodegenerative language disturbance. The cognitive mechanisms that may underlie this case are discussed.

  10. Neurocognitive impairment in obstructive sleep apnea.

    Lal, Chitra; Strange, Charlie; Bachman, David

    2012-06-01

    Obstructive sleep apnea syndrome (OSAS) is a common disorder with far-reaching health implications. One of the major consequences of OSAS is an impact on neurocognitive functioning. Several studies have shown that OSAS has an adverse effect on inductive and deductive reasoning, attention, vigilance, learning, and memory. Neurocognitive impairment can be measured objectively with tests such as the Wechsler Adult Intelligence Scale-Revised, the Psychomotor Vigilance Task, the Steer Clear Performance Test, and tests of repetitive finger tapping. In children, OSAS may cause attention-deficit hyperactivity disorder in addition to behavioral problems and learning disabilities. Risk factors for cognitive impairment include increasing age, male sex, apolipoprotein E ε4 allele positivity, current cigarette smoking, obesity, hypertension, diabetes mellitus, metabolic syndrome, Down syndrome, hypothyroidism, significant alcohol consumption, stroke, and the use of psychoactive medications. At a cellular level, OSAS likely causes cognitive impairment through intermittent hypoxia, hormonal imbalance, and/or systemic inflammation, either independently or via the resultant endothelial dysfunction that occurs. Excessive daytime sleepiness should be measured and minimized in all studies of neurocognitive impairment. Recent studies have used functional and structural neuroimaging to delineate the brain areas affected in patients with OSAS with neurocognitive dysfunction. A common finding in several of these studies is decreased hippocampal volume. Other affected brain areas include the frontal and parietal lobes of the brain, which show focal reductions in gray matter. These changes can be reversed at least partially with the use of CPAP, which highlights the importance of early recognition and treatment of OSAS. The currently available data in this field are quite limited, and more research is needed.

    A stratified random cluster sample of 15,845 subjects was performed in two regions of Nepal to determine the prevalence and main causes of hearing impairment (the most common disability) and the prevalence of ear disease. Subjects reporting current ear pain, or ear discharge, or hearing impairment on direct questioning by a Nepali health worker (primary screening failed), had otoscopy and audiometry (using the Liverpool Field Audiometer) performed, and a questionnaire administered relating to past history. In every fifth house subjects who passed the primary screening (1,716 subjects) were examined to assess the false negative rate of screening. An estimated 16.6 per cent of the study population have hearing impairment (either ear worse than 30 dB hearing threshold level (HTL) 1.0-4.0 kHz, or 50 dB HTL 0.5 kHz), and 7.4 per cent ear drum pathology, equivalent to respectively 2.71 and 1.48 million people extrapolated to the whole of Nepal. Most hearing impairment in the school age group (55.2 per cent) is associated with otitis media or its sequelae. Probably at least 14 per cent of sensorineural deafness is preventable (7 per cent infectious disease, 3.9 per cent trauma, 0.8 per cent noise exposure, 1 per cent cretinism, and 1 per cent abnormal pregnancy or labour). Most individuals reporting current ear pathology (61 per cent) had never attended a health post, and of those receiving ear drop treatment, 84 per cent still had serious pathology. Of subjects who reported ear drop treatment at any time, 31 per cent still had serious pathology. The use of traditional remedies was prevalent.(ABSTRACT TRUNCATED AT 250 WORDS)

    Attention-deficit hyperactivity disorder (ADHD) is a prevalent psychiatric disorder in children that often continues into adulthood. It has been suggested that motor impairments in ADHD are associated with underlying cerebellar pathology. If such is the case, individuals with ADHD should be impaired on motor tasks requiring healthy cerebellar function. To test this, we compared performance of individuals with ADHD and ADHD-like symptoms with non-ADHD controls on a visuomotor adaptation task known to be impaired following cerebellar lesions. Participants adapted reaching movements to a visual representation that was rotated by 30°. Individuals with ADHD and those with ADHD-like symptoms took longer to correct the angle of movement once the rotation was applied relative to controls. However, post-adaptation residual effect did not differ for individuals with ADHD and ADHD-like symptoms compared to the control group. These results are consistent with the hypothesis that mild cerebellar deficits are evident in the motor performance of adults with ADHD.

    2012-01-01

    FTLD consists of three clinical types: behavioural variant FTD, progressive non-fluent aphasia (PNFA) and semantic dementia (SD). The latter two types manifest aphasia. Thus, it is quite important to pertinently assess the symptoms of aphasia and related impairments for diagnosis of FTLD. The most important point for diagnosis of PNFA is existence of anarthria/apraxia of speech, which is a focal symptom of the left prefrontal gyrus and underlying white matter. With the progression of the disease word generation and comprehension is deteriorating. SD shows Gogi aphasia when the lesion have predilection of left temporal lober atrophy. We investigated 28 patients without any antecedents causing speech/language impairments, who developed primary progressive aphasia. All the patients underwent a routine neurological and neuropsychological examinations and related symptoms such as orofacial apraxia, frontal lobe signs, dysphasia and so on were assessed. The results indicated that 20 patients were diagnosed as PNFA, and they were subdivided into three clinical groups. One group developed naming impairment and orofacial apraxia in several years after onset, and followed with various frontal symptoms. Another group showed anterior opereculum syndromes within two years after onset. The third group retained pure anarthria/apraxia of speech for many years without any other symptoms.

    2014-04-01

    Dysarthria is a common symptom of Huntington's disease and has been reported, besides other features, to be characterized by alterations of speech rate and regularity. However, data on the specific pattern of motor speech impairment and their relationship to other motor and neuropsychological symptoms are sparse. Therefore, the aim of the present study was to describe and objectively analyse different speech parameters with special emphasis on the aspect of speech timing of connected speech and non-speech verbal utterances. 21 patients with manifest Huntington's disease and 21 age- and gender-matched healthy controls had to perform a reading task and several syllable repetition tasks. Computerized acoustic analysis of different variables for the measurement of speech rate and regularity generated a typical pattern of impaired motor speech performance with a reduction of speech rate, an increase of pauses and a marked disability to steadily repeat single syllables. Abnormalities of speech parameters were more pronounced in the subgroup of patients with Huntington's disease receiving antidopaminergic medication, but were also present in the drug-naïve patients. Speech rate related to connected speech and parameters of syllable repetition showed correlations to overall motor impairment, capacity of tapping in a quantitative motor assessment and some score of cognitive function. After these preliminary data, further investigations on patients in different stages of disease are warranted to survey if the analysis of speech and non-speech verbal utterances might be a helpful additional tool for the monitoring of functional disability in Huntington's disease.

  5. Deficits in episodic memory retrieval reveal impaired default mode network connectivity in amnestic mild cognitive impairment

    2014-01-01

    Full Text Available Amnestic mild cognitive impairment (aMCI is believed to represent a transitional stage between normal healthy ageing and the development of dementia. In particular, aMCI patients have been shown to have higher annual transition rates to Alzheimer's Disease (AD than individuals without cognitive impairment. Despite intensifying interest investigating the neuroanatomical basis of this transition, there remain a number of questions regarding the pathophysiological process underlying aMCI itself. A number of recent studies in aMCI have shown specific impairments in connectivity within the default mode network (DMN, which is a group of regions strongly related to episodic memory capacities. However to date, no study has investigated the integrity of the DMN between patients with aMCI and those with a non-amnestic pattern of MCI (naMCI, who have cognitive impairment, but intact memory storage systems. In this study, we contrasted the DMN connectivity in 24 aMCI and 33 naMCI patients using seed-based resting state fMRI. The two groups showed no statistical difference in their DMN intra-connectivity. However when connectivity was analysed according to performance on measures of episodic memory retrieval, the two groups were separable, with aMCI patients demonstrating impaired functional connectivity between the hippocampal formation and the posterior cingulate cortex. We provide evidence that this lack of connectivity is driven by impaired communication from the posterior cingulate hub and does not simply represent hippocampal atrophy, suggesting that posterior cingulate degeneration is the driving force behind impaired DMN connectivity in aMCI.

    GLUT4 in muscle and adipose tissue is important in maintaining glucose homeostasis. However, the role of insulin-responsive GLUT4 in the central nervous system has not been well characterized. To assess its importance, a selective knockout of brain GLUT4 (BG4KO) was generated by crossing Nestin-Cre mice with GLUT4-floxed mice. BG4KO mice had a 99% reduction in GLUT4 protein expression throughout the brain. Despite normal feeding and fasting glycemia, BG4KO mice were glucose intolerant, demonstrated hepatic insulin resistance, and had reduced glucose uptake in the brain. In response to hypoglycemia, BG4KO mice had impaired glucose sensing, noted by impaired epinephrine and glucagon responses and impaired c-fos activation in the hypothalamic paraventricular nucleus. Moreover, in vitro glucose sensing of glucose-inhibitory neurons from the ventromedial hypothalamus was impaired in BG4KO mice. In summary, BG4KO mice are glucose intolerant, insulin resistant, and have impaired glucose sensing, indicating a critical role for brain GLUT4 in sensing and responding to changes in blood glucose.

    Video compression technologies are essential in video streaming application because they could save a great amount of network resources. However compressed videos are also extremely sensitive to packet loss which is inevitable in today's best effort IP network. Therefore we think accurate evaluation of packet loss impairment on compressed video is very important. In this work, we develop an analytic model to describe these impairments without the reference of the original video (NR) and propose an impairment metric based on the model, which takes into account both impairment length and impairment strength. To evaluate an impaired frame or video, we design a detection and evaluation algorithm (DE algorithm) to compute the above metric value. The DE algorithm has low computational complexity and is currently being implemented in the real-time monitoring module of our HDTV over IP system. The impairment metric and DE algorithm could also be used in adaptive system or be used to compare diffeient error concealment strategies.

    1996-11-01

    Four experiments tested the effects in the rat of very early experience with stimuli to be used later for Pavlovian conditioning. Beginning on postnatal Day 12, prior to the development of substantial detection and effective perception of visual and auditory stimuli, rats were given five daily experiences with either lights or tones and a footshock known to be an effective unconditioned stimulus at these ages. Twenty-four hours after the last of these experiences, pairings of either the light or tone and the unconditioned stimulus were given with parameters established to yield a moderate degree of conditioning in untreated preweanlings (Experiment 1). Experiment 2 determined that early experience with paired or unpaired presentations of either the light or tone and the unconditioned stimulus resulted in a failure to condition to these same lights or tones on postnatal Day 17, although nontreated pups from the same litters conditioned quite effectively. Experiment 3 determined that this early conditioning experience with either paired or unpaired presentations of the lights or tones and the unconditioned stimulus yielded impaired conditioning on postnatal Day 17 in the alternative sensory modality as well, although again nontreated siblings conditioned quite effectively. Experiment 4 replicated the results of each of Experiments 2 and 3 and determined in addition that despite the impairment in conditioning that resulted from early paired or unpaired experience with the stimuli of conditioning, early experience with the individual stimuli of conditioning-with only the CS, the US, or the context-did not result in a similar impairment in conditioning. Although the results were unexpected, they may be understood in part in terms of intersensory competition during development, and there is precedent in the literature for similar interfering effects of early learning on later learning in a variety of species.

    Full Text Available Objectives: The study of cervical muscles and their significance in the development and perpetuation of Temporomandibular Disorders has not been elucidated. Thus this project was designed to investigate the association between cervical musculoskeletal impairments and Temporomandibular Disorders. Material and Methods: A sample of 154 subjects participated in this study. All subjects underwent a series of physical tests and electromyographic assessment (i.e. head and neck posture, maximal cervical muscle strength, cervical flexor and extensor muscles endurance, and cervical flexor muscle performance to determine cervical musculoskeletal impairments. Results: A strong relationship between neck disability and jaw disability was found (r = 0.82. Craniocervical posture was statistically different between patients with myogenous Temporomandibular Disorders (TMD and healthy subjects. However, the difference was too small (3.3º to be considered clinically relevant. Maximal cervical flexor muscle strength was not statistically or clinically different between patients with TMD and healthy subjects. No statistically significant differences were found in electromyographic activity of the sternocleidomastoid or the anterior scalene muscles in patients with TMD when compared to healthy subjects while executing the craniocervical flexion test (P = 0.07. However, clinically important effect sizes (0.42 - 0.82 were found. Subjects with TMD presented with reduced cervical flexor as well as extensor muscle endurance while performing the flexor and extensor muscle endurance tests when compared to healthy individuals. Conclusions: Subjects with Temporomandibular Disorders presented with impairments of the cervical flexors and extensors muscles. These results could help guide clinicians in the assessment and prescription of more effective interventions for individuals with Temporomandibular Disorders.

    Anorexia nervosa (AN) is a severe mental illness, which is characterized by a continuously growing occurrence in the population and by the shift of the onset for earlier ages. The understanding of factors playing role in AN and the importance of effective prevention is an essential issue in science as well as in the society. AN also affects the social domain of life, patients with AN may exhibit impaired social interaction, social isolation, difficulties in emotion recognition and egocentric thinking in cognitive processing. Therefore, the aim of present study was to investigate the theory of mind (ToM) deficits is anorexia nervosa. Although previous studies have reported ToM deficits in autism and in schizophrenia, the number of studies investigating ToM functioning in eating disorders are particularly low. Even though ToM difficulties, such as the affective ToM impairments were found in AN, however, the evidence of cognitive ToM deficits in anorexia patients is still lacking. Twenty anorexia nervosa patients and 20 healthy control adolescent girls participated in the experiment. EDI, BAT, Fallon-Rozin Test and Anamoprhic Micro Body Image Assesment Programme questionnaires and body-image tests were applied to discriminate anorexia nervosa group from healthy control group. The Hungarian version of Faux Pas Recognition Test was applied to evaluate ToM functioning. Compared to healthy control group, impairment in ToM functioning was found in AN group, especially in affective mental state attribution. Our results can raise new aspects for research, therapy and prevention of anorexia nervosa.

    Hypersexuality, also referred to in the literature as sexually inappropriate behavior and sexual disinhibition, involves persistent, uninhibited sexual behaviors directed at oneself or at others. For older adults, the literature generally attributes the behavior to biochemical or physiological changes that accompany cognitive impairment-specifically, dementia. Although less common than other behavioral issues, such as aggression and agitation, hypersexuality presents complex logistical and ethical problems for caregivers. This article reviews the current literature on hypersexual behavior. Assessment essentials as well as nonpharmacological and pharmacological treatment approaches are discussed, identifying the need for standardization as well as caregiver education and training.

  19. Noise-induced hearing impairment and handicap

    Science.gov (United States)

    1984-01-01

    A permanent, noise-induced hearing loss has doubly harmful effect on speech communications. First, the elevation in the threshold of hearing means that many speech sounds are too weak to be heard, and second, very intense speech sounds may appear to be distorted. The whole question of the impact of noise-induced hearing loss upon the impairments and handicaps experienced by people with such hearing losses was somewhat controversial partly because of the economic aspects of related practical noise control and workmen's compensation.

    Full Text Available We proposed to investigate subclinical cognitive impairment secondary to chronic Chagas' disease (CCD. No similar study was previously done. The neuropsychological performance of 45 chronic Chagasic patients and 26 matched controls (age, education place and years of residency in endemic area was compared using the Mini Mental State Exam (MMSE, Weschler Memory Scale (WMS and the Weschler Adult Intelligent Scale (WAIS. Non-parametric tests and Chi2 were used to compare group means and multivariate statistics in two way frequency tables for measures of independence and association of categorical variables with the disease. Results: Chagasic patients showed lower MMSE scores (p<004, poor orientation (p<.004, and attention (p<.007. Lower WMS MQ were associated with CCD (Chi2 5.9; p<.01; Fisher test p<.02. Lower WAIS IQ were associated with CCD (Chi2 6.3, p<.01; Fisher test p<.01 being the digit symbol (p<.03, picture completion (p<.03, picture arrangement (p<.01 and object assembly (p<.03 subtests the most affected. The impairment in non-verbal reasoning, speed of information processing, problem solving, learning and sequencing observed in chronic Chagas disease patients resembles the cognitive dysfunction associated with white matter disease.

    Stress interferes with instrumental learning. However, choice is also influenced by non-instrumental factors, most strikingly by biases arising from Pavlovian associations that facilitate action in pursuit of rewards and inaction in the face of punishment. Whether stress impacts on instrumental learning via these Pavlovian associations is unknown. Here, in a task where valence (reward or punishment) and action (go or no-go) were orthogonalised, we asked whether the impact of stress on learning was action or valence specific. We exposed 60 human participants either to stress (socially-evaluated cold pressor test) or a control condition (room temperature water). We contrasted two hypotheses: that stress would lead to a non-selective increase in the expression of Pavlovian biases; or that stress, as an aversive state, might specifically impact action production due to the Pavlovian linkage between inaction and aversive states. We found support for the second of these hypotheses. Stress specifically impaired learning to produce an action, irrespective of the valence of the outcome, an effect consistent with a Pavlovian linkage between punishment and inaction. This deficit in action-learning was also reflected in pupillary responses; stressed individuals showed attenuated pupillary responses to action, hinting at a noradrenergic contribution to impaired action-learning under stress.

  5. Impairments of social motor coordination in schizophrenia.

    Directory of Open Access Journals (Sweden)

    Manuel Varlet

    Full Text Available It has been demonstrated that motor coordination of interacting people plays a crucial role in the success of social exchanges. Abnormal movements have been reported during interpersonal interactions of patients suffering from schizophrenia and a motor coordination breakdown could explain this social interaction deficit, which is one of the main and earliest features of the illness. Using the dynamical systems framework, the goal of the current study was (i to investigate whether social motor coordination is impaired in schizophrenia and (ii to determine the underlying perceptual or cognitive processes that may be affected. We examined intentional and unintentional social motor coordination in participants oscillating hand-held pendulums from the wrist. The control group consisted of twenty healthy participant pairs while the experimental group consisted of twenty participant pairs that included one participant suffering from schizophrenia. The results showed that unintentional social motor coordination was preserved while intentional social motor coordination was impaired. In intentional coordination, the schizophrenia group displayed coordination patterns that had lower stability and in which the patient never led the coordination. A coupled oscillator model suggests that the schizophrenia group coordination pattern was due to a decrease in the amount of available information together with a delay in information transmission. Our study thus identified relational motor signatures of schizophrenia and opens new perspectives for detecting the illness and improving social interactions of patients.

    Memory generalization is essential for adaptive decision-making and action. Our ability to generalize across past experiences relies on medial-temporal lobe structures, known to be highly sensitive to stress. Recent evidence suggests that stressful events may indeed interfere with memory generalization. Yet, the mechanisms involved in this generalization impairment are unknown. We tested here whether a pharmacological elevation of major stress mediators, noradrenaline, and glucocorticoids is sufficient to disrupt memory generalization. In a double-blind, placebo-controlled design, healthy men and women received orally a placebo, hydrocortisone, the α2-adrenoceptor antagonist yohimbine that leads to increased noradrenergic stimulation, or both drugs, before they completed an associative learning task probing memory generalization. Drugs left learning performance intact. Yohimbine, however, led to a striking generalization impairment in women, but not in men. Hydrocortisone, in turn, had no effect on memory generalization, neither in men nor in women. The present findings indicate that increased noradrenergic activity, but not cortisol, is sufficient to disrupt memory generalization in a sex-specific manner, with relevant implications for stress-related mental disorders characterized by generalization deficits.

    Background Mild cognitive impairment (MCI) is a transitional state between normal ageing and dementia, at least for some patients. Behavioral symptoms in MCI are associated with a higher risk of dementia, but their association with dementia risk in patients without MCI is unknown. Mild Behavioral Impairment (MBI) refers to a late life syndrome with prominent psychiatric and related behavioral symptoms in the absence of prominent cognitive symptoms, which may also be a dementia prodrome. Objective To compare MCI and MBI patients and to estimate the risk of dementia development in these two groups. Method A consecutive series of 358 patients (239 with MCI; and 119 with MBI) presenting to an outpatient general hospital specialty clinic were followed for up to 5 years until conversion to dementia or censoring. Results 34% of MCI patients and over 70% of patients with MBI developed dementia (Logrank p=0.011). MBI patients without cognitive symptoms were more likely to develop dementia (Logrank p<0.001). MBI patients were more likely to develop dementia due to frontotemporal degeneration (FTD) as opposed to Alzheimer’s dementia (AD). Conclusion MBI appears to be a transitional state between normal ageing and dementia. MBI (specifically those without cognitive symptoms) may confer a higher risk for dementia than MCI and is likely an FTD prodrome in many cases. These findings have implications for the early detection, prevention, and treatment of patients with dementia in late life, by focusing on the emergence of new behavioral symptoms. PMID:19323967

  8. Neurocognitive impairment in childhood chronic fatigue syndrome

    Full Text Available Neurocognitive impairment is a feature of childhood chronic fatigue syndrome (CCFS. Several studies have demonstrated reduced attention control in CCFS patients in switching and divided attention tasks. In students, the extent of deterioration in task performance depends on the level of fatigue. Poor performance in switching and divided attention is common in both fatigued students and CCFS patients. Additionally, attentional functions show dramatic development from childhood to adolescence, suggesting that abnormal development of switching and divided attention may be induced by chronic fatigue. The brain structures associated with attentional control are situated in the frontal and parietal cortices, which are the last to mature, suggesting that severe fatigue in CCFS patients and students may inhibit normal structural and functional development in these regions. A combination of treatment with cognitive behavioral therapy and antidepressant medication is effective to improve attentional control processing in CCFS patients. Studies identifying the features of neurocognitive impairment in CCFS have improved our current understanding of the neurophysiological mechanisms of CCFS.

    Full Text Available Background: Retinal microvascular network changes have been found in patients with age-related brain diseases such as stroke and dementia including Alzheimer's disease. We examine whether retinal microvascular network changes are also present in preclinical stages of dementia. Methods: This is a cross-sectional study of 300 Chinese participants (age: ≥60 years from the ongoing Epidemiology of Dementia in Singapore study who underwent detailed clinical examinations including retinal photography, brain imaging and neuropsychological testing. Retinal vascular parameters were assessed from optic disc-centered photographs using a semiautomated program. A comprehensive neuropsychological battery was administered, and cognitive function was summarized as composite and domain-specific Z-scores. Cognitive impairment no dementia (CIND and dementia were diagnosed according to standard diagnostic criteria. Results: Among 268 eligible nondemented participants, 78 subjects were categorized as CIND-mild and 69 as CIND-moderate. In multivariable adjusted models, reduced retinal arteriolar and venular fractal dimensions were associated with an increased risk of CIND-mild and CIND-moderate. Reduced fractal dimensions were associated with poorer cognitive performance globally and in the specific domains of verbal memory, visuoconstruction and visuomotor speed. Conclusion: A sparser retinal microvascular network, represented by reduced arteriolar and venular fractal dimensions, was associated with cognitive impairment, suggesting that early microvascular damage may be present in preclinical stages of dementia.

    Full Text Available Mild Cognitive Impairment (MCI causes slight but noticeable disruption in cognitive systems, primarily executive and memory functions. However, it is not clear if the development of sequence learning is affected by an impaired cognitive system and, if so, how. The goal of our study was to investigate the development of probabilistic sequence learning, from the initial acquisition to consolidation, in MCI and healthy elderly control groups. We used the Alternating Serial Reaction Time task (ASRT to measure probabilistic sequence learning. Individuals with MCI showed weaker learning performance than the healthy elderly group. However, using the reaction times only from the second half of each learning block – after the reactivation phase - we found intact learning in MCI. Based on the assumption that the first part of each learning block is related to reactivation/recall processes, we suggest that these processes are affected in MCI. The 24-hour offline period showed no effect on sequence-specific learning in either group but did on general skill learning: the healthy elderly group showed offline improvement in general reaction times while individuals with MCI did not. Our findings deepen our understanding regarding the underlying mechanisms and time course of sequence acquisition and consolidation.

    Cognitive models propose a hierarchy of parallel processing stages in face perception, and functional neuroimaging shows a network of regions involved in face processing. Reflecting this, acquired prosopagnosia is not a single entity but a family of disorders with different anatomic lesions and different functional deficits. One classic distinction is between an apperceptive variant, in which there is impaired perception of facial structure, and an associative/amnestic variant, in which perception is relatively intact, with subsequent problems matching perception to facial memories, because of either disconnection or loss of those memories. These disorders also have to be distinguished from people-specific amnesia, a multimodal impairment, and prosop-anomia, in which familiarity with faces is preserved but access to names is disrupted. These different disorders can be conceived as specific deficits at different processing stages in cognitive models, and suggests that these functional stages may have distinct neuroanatomic substrates. It remains to be seen whether a similar anatomic and functional variability is present in developmental prosopagnosia.

    Full Text Available Background. Psychiatric consultation is necessary for all patients with intentional poisoning and its reliability depends on the proper function of patients’ memory performance. This study aimed to determine the possible memory impairment following acute TCAs’ poisoning. Materials and Methods. In this cross-sectional study, patients with acute TCAs poisoning were allocated to two groups of severe poisoning (with coma, seizures, cardiac arrhythmias, hypotension, and a wide QRS complex and mild-to-moderate poisoning according to their clinical presentation at the time of hospital admission. All patients underwent memory performance test both immediately and 24 hours after their initial consciousness after admission, using Wechsler Memory Scale (WMS-IV. Results. During the study period, 67 TCA-poisoned patients (aged, 20–64 years were evaluated, of which 67.2% were female. The mean memory scores of patients immediately and 24 hours after the initial consciousness were 31.43±9.02 and 50.62±9.12, respectively (P<0.001. Twenty-four hours after the initial consciousness, memory score was statistically correlated with the amount of ingested drug and the intoxication severity. Conclusion. Following the recovery from somatic symptoms of acute TCA poisoning, patients may still suffer from memory impairment and it seems that this time is not suitable for performing a reliable psychiatric consultation.

    Unique computational techniques are used to calculate apportionment percentages for Whole Person Impairment (WPI) Ratings for workers with job-related injuries/illnesses. This interdisciplinary project includes collaboration among physicists, engineers, and concerned medical professionals. Medical providers are often asked to medically determine multiple contributing factors to disease states (e.g. diabetes, obesity, arthritis, and prior injury) in the context of personal injury as it pertains to permanent impairment. The process of making this determination is referred to as ``apportionment''. The economic value of apportionment is far reaching and represents a significant impact to all stakeholders in the injury resolution and settlement arena. The process of apportionment is necessary to assign monetary value for the stakeholders when an injury occurs. The ultimate trier-of-fact is the judicial system. The medical provider's role in this capacity is to apply known medical scientific knowledge and present it in a format that is objective and reproducible for the stakeholders. In this presentation the traditional challenges of apportionment will be outlined, and a novel approach creating mathematical bounding and modeling of pathology-weighted data sets will be presented.

    Full Text Available A significant number of individuals with severe motor impairments are unable to control their wheelchair using a standard joystick. Even when they can facilitate the control input, navigation in a confined space or crowded environments is still a great challenge. Here we propose a wheelchair framework that enables the user to issue the command via a multi‐input hands free interface (HFI, which subsequently assists him/her to overcome difficult circumstances using a multimodal control strategy. Initially the HFI inputs are analysed to infer the desired control mode and the user command. Then environmental information is perceived using a combination of laser and Kinect sensors for determining all possible obstacle locations and outputting a safety map around the wheelchair’s vicinity. Eventually, the user’s command is validated with the safety map to moderate the final motion, which is collision free and the best for the user’s preference. The proposed method can reduce the burden of severe impairment users when controlling wheelchairs by continuously monitoring the surroundings and can make them move easily according to the users’ intention.

    The purpose of this study was to determine whether severity of disease, cognitive function, age, gender, or amount of social interaction were associated with pragmatic dysfunction in Parkinson disease. No studies have previously been done to investigate variables that may be associated with pragmatic dysfunction in Parkinson disease. A case-control study was conducted with 17 Parkinson disease patients and 17 convenience controls. Each Parkinson disease patient and a control were interviewed, and their pragmatic skills were evaluated using a scale of pragmatic communication skills. Correlation analysis was used to determine what factors were associated with pragmatic dysfunction in the Parkinson disease patients. Cases scored lower on the pragmatic scale with a mean of 29.7 compared with 38.9 in the controls (p pragmatic communication skills had moderate to strong correlations with the MMSE (r = .81, p = .002), Unified Parkinson's Disease Rating Scale score (r = -.71, p = .002), and duration of disease (r = -.53, p = .03). These results show that Parkinson disease patients have impaired pragmatic function compared with controls on both verbal and nonverbal sections, and this impairment correlates with mental state, duration, and severity of disease.

    Patients with memory disorders have severely restricted learning and memory. For instance, patients with anterograde amnesia can learn motor procedures and retain some restricted ability to learn new words and factual information. However, such learning is inflexible and frequently inaccessible to conscious awareness. Here we present a case of patient AC596, a 25-year-old male with severe episodic memory impairments, presumably due to anoxia during a preterm birth. In contrast to his poor episodic memory, he exhibits savant-like memory for calendar information that can be flexibly accessed by day, month, and year cues. He also has the ability to recollect the exact date of a wide range of personal experiences over the past 20 years. The patient appears to supplement his generally poor episodic memory by using memorized calendar information as a retrieval cue for autobiographical events. These findings indicate that islands of preserved memory functioning, such as a highly developed semantic memory system, can exist in individuals with severely impaired episodic memory systems. In this particular case, our patient's memory for dates far outstripped that of normal individuals and served as a keen retrieval cue, allowing him to access information that was otherwise unavailable.

    1983-06-01

    In recognition of the special needs of hearing-impaired employees, Union Carbide Nuclear Division staff members restructured and rewrote the existing Career Planning Program to accommodate the barriers experienced by deaf people. Consideration for reworking the training program included awareness that hearing-impaired people: learn mostly through their eyes; use sign language, which is grammatically and structurally different than the English language; have a limited understanding of the English language; live in an isolated world influenced mostly by the deaf community; and have sometimes been stigmatized because of their handicap, resulting in the belief by their parents and others in the hearing world that they lack in intelligence and ability. Twelve deaf employees participated in the program, including four from the Oak Ridge Gaseous Diffusion Plant, six from the Oak Ridge National Laboraory, and two from the Department of Energy. All twelve employees completed the 6 1/2 days of sessions spanning over six weeks, evaluating the program overall as very good. Although most did not feel a need for career change, they learned strategies for enhancing and developing their current positions. They also discovered they were not alone in many feelings of isolation or lack of self-confidence, and that many of their problems are shared by hearing people.

  18. A conceptual framework for evaluating impairments in myasthenia gravis.

    Directory of Open Access Journals (Sweden)

    Carolina Barnett

    Full Text Available BACKGROUND: Myasthenia gravis is characterized by weakness and fatigability of different muscle groups, including ocular, bulbar and the limbs. Therefore, a measure of disease severity at the impairment level in myasthenia needs to reflect all the relevant impairments, as well as their variations with activity and fatigue. We conducted a qualitative study of patients with myasthenia, to explore their experiences and related impairments, aimed at developing a conceptual framework of disease severity at the impairment level in myasthenia gravis. METHODS: Twenty patients representing the spectrum of disease participated in semi-structured interviews. Interviews were recorded and the transcripts were analyzed by content analysis using an inductive approach with line-by-line open coding. Themes were generated from these codes. RESULTS: Two main themes were identified: the severity of the impairments and fatigability (i.e., triggering or worsening of an impairment with activity. The impairments were further classified within body regions (ocular, bulbar and axial/limbs. Fatigability was described as a phenomenon affecting the whole body but also affecting specific impairments, and was associated with fluctuation of the symptoms. Patients were concerned that clinical examination at a single point in time might not reflect their true clinical state due to fatigability and fluctuations in severity. CONCLUSIONS: This conceptual framework reflects the relevance of both severity and fatigability in understanding impairment-based disease severity in myasthenia. This framework could inform the development of impairment measures in myasthenia gravis.

    Full Text Available The research included 200 visually impaired children of primary school during the period from 1992 to 1996. By means of adequate instruments we have tested the relation between the success at school of partially seeing children and hyperkinetic behavior, active and passive vocabulary richness, visuo-motoric coordination and the maturity of handwriting. Besides the already known factors (intellectual level, specific learning disturbances, emotional and neurotic disturbances, cultural deprivation, the success in class depends very much on the intensity of hyperkinetic behavior as well as its features: unstable attention, impulsiveness and hyperactivity. Visual-motor coordination eye-hand and the maturity of handwriting have a strong influence on their success at school.

    Models of speech intelligibility (SI) have a long history, starting with the articulation index (AI, [17]), followed by the SI index (SI I, [18]) and the speech transmission index (STI, [7]), to only name a few. However, these models fail to accurately predict SI with nonlinearly processed noisy...... speech, e.g. phase jitter or spectral subtraction. Recent studies predict SI for normal-hearing (NH) listeners based on a signal-to-noise ratio measure in the envelope domain (SNRenv), in the framework of the speech-based envelope power spectrum model (sEPSM, [20, 21]). These models have shown good...... agreement with measured data under a broad range of conditions, including stationary and modulated interferers, reverberation, and spectral subtraction.

    The occurrence of cognitive disturbances upon CNS inflammation or infection has been correlated with increased levels of the cytokine tumor necrosis factor-α (TNFα). To date, however, no specific mechanism via which this cytokine could alter cognitive circuits has been demonstrated. Here, we show that local increase of TNFα in the hippocampal dentate gyrus activates astrocyte TNF receptor type 1 (TNFR1), which in turn triggers an astrocyte-neuron signaling cascade that results in persistent functional modification of hippocampal excitatory synapses. Astrocytic TNFR1 signaling is necessary for the hippocampal synaptic alteration and contextual learning-memory impairment observed in experimental autoimmune encephalitis (EAE), an animal model of multiple sclerosis (MS). This process may contribute to the pathogenesis of cognitive disturbances in MS, as well as in other CNS conditions accompanied by inflammatory states or infections.

    Cognitive damage in heart failure (HF) involves different domains thus interfering with the ability for single patient to self-care and to cope with treatment regimens, modifying symptoms and health behaviours. Many cerebral and functional changes were detected in brain imaging, involving areas of both grey and white matter deputed to cognition. Although various instruments are available to explore cognition, no consensus was obtained on better tools to be used in HF population. Reduction in cerebral blood flow, decreased cardiac output, altera-tions of cerebrovascular reactivity and modification of blood pressure levels are the main features involved in the etiopathogenetic mecha-nisms of cognitive deficit. Several cardiac variables, laboratory parameters, demographic and clinical elements were studied for their possible relation with cognition and should be properly evaluated to define patients at increased risk of impairment. The present review gathers avail-able data pointing out assured information and discussing possible areas of research development.

    Vascular dementia (VaD) is increasingly recognised to reflect an outmoded concept in that it identifies cases too late for preventive therapy to have an opportunity to prevent the development of dementia and uses a cognitive paradigm inappropriately based on Alzheimer's disease. A replacement is urgently required and a new concept, that of vascular cognitive impairment (VCI), has been proposed to meet this need. It is imperative that criteria for VCI are developed on the basis of knowledge and data rather than supposition and assumption, as was the case for VaD. This review details the state of knowledge that we have now reached concerning the fundamental points of severity and cognitive paradigm and also covers a number of other imaging-related essential points embracing atrophy, leukoaraiosis, infarct volume and infarct location. Finally, the increasingly important concept of mixed dementia (co-existent Alzheimer's disease and VCI) is discussed.

    Laurence Mangin

    Full Text Available Ventilatory chaos is strongly linked to the activity of central pattern generators, alone or influenced by respiratory or cardiovascular afferents. We hypothesized that carotid atherosclerosis should alter ventilatory chaos through baroreflex and autonomic nervous system dysfunctions. Chaotic dynamics of inspiratory flow was prospectively evaluated in 75 subjects undergoing carotid ultrasonography: 27 with severe carotid stenosis (>70%, 23 with moderate stenosis (<70%, and 25 controls. Chaos was characterized by the noise titration method, the correlation dimension and the largest Lyapunov exponent. Baroreflex sensitivity was estimated in the frequency domain. In the control group, 92% of the time series exhibit nonlinear deterministic chaos with positive noise limit, whereas only 68% had a positive noise limit value in the stenoses groups. Ventilatory chaos was impaired in the groups with carotid stenoses, with significant parallel decrease in the noise limit value, correlation dimension and largest Lyapunov exponent, as compared to controls. In multiple regression models, the percentage of carotid stenosis was the best in predicting the correlation dimension (p<0.001, adjusted R(2: 0.35 and largest Lyapunov exponent (p<0.001, adjusted R(2: 0.6. Baroreflex sensitivity also predicted the correlation dimension values (p = 0.05, and the LLE (p = 0.08. Plaque removal after carotid surgery reversed the loss of ventilatory complexity. To conclude, ventilatory chaos is impaired in carotid atherosclerosis. These findings depend on the severity of the stenosis, its localization, plaque surface and morphology features, and is independently associated with baroreflex sensitivity reduction. These findings should help to understand the determinants of ventilatory complexity and breathing control in pathological conditions.

    Full Text Available Spelling deficits have repeatedly been observed in children with dyslexia. However, the few studies addressing this issue in dyslexic adults have reported contradictory results. We investigated whether Spanish dyslexics show spelling deficits in adulthood and which components of the writing production process might be impaired in developmental dyslexia. In order to evaluate the involvement of the lexical and the sublexical routes of spelling as well as the graphemic buffer, lexical frequency, phonology-to-orthography consistency and word length were manipulated in two writing tasks: a direct copy transcoding task and a spelling-to-dictation task. Results revealed that adults with dyslexia produced longer written latencies, inter-letter intervals, writing durations and more errors than their peers without dyslexia. Moreover, the dyslexics were more affected by lexical frequency and word length than the controls, but both groups showed a similar effect of P-O consistency. Written latencies also revealed that while the dyslexics initiated the response later in the direct copy transcoding task than in the spelling-to-dictation task, the controls showed the opposite pattern. However, the dyslexics were slower than the controls in both tasks. Results were consistent with the hypothesis that spelling difficulties are present in adults with dyslexia, at least in a language with a transparent orthography such as Spanish. These difficulties seem to be associated with a deficit affecting both lexical processing and the ability to maintain information about the serial order of the letters in a word. However, the dyslexic group did not differ from the control group in the application of the P-O conversion procedures. The spelling impairment would be in addition to the reading deficit, leading to poorer performance in direct copy transcoding compared to spelling-to-dictation.

    A multichannel electronic visual aid device which is able to signal to the user whether sound is coming from the left or right, front or back, or both is presented. For the plurality of channels, which may operate in pairs, the sound is picked up by a respective microphone and amplified and rectified into a DC voltage. The DC voltage is next fed to an analog to digital converter and then to a digital encoder. The binary code from the encoder is coupled into a logic circuit where the binary code is decoded to proved a plurality of output levels which are used to drive an indicator which, in turn, provides a visual indication of the sound level received. The binary codes for each pair of channels are also fed into a digital comparator. The output of the comparator is used to enable the logic circuits of the two channels such that if, for example, the signal coming from the right is louder than that coming from the left, the output of the logic unit of the right channel will be enabled and the corresponding indicator activated, indicating the sound source on the right. An indication of the loudness is also provided. One embodiment of the invention may be carried by the hearing impaired or deaf, as a system which is embedded into eye glasses or a cap. Another embodiment of the invention may be integrated with a vehicle to give a hearing impaired or deaf driver a warning, with a directional indication, that an emergency vehicle is in the vicinity. In this second embodiment, the emergency vehicle transmits a radio frequency signal which would be used as an enabling signal for the visual aid device to avoid false alarms from traffic and other sound sources in the vicinity of the driver's vehicle.

    Load Carriage using backpacks is an occupational task and can be a recreational pursuit. The aim of this study was to investigate the mechanisms responsible for changes in neuromuscular function of the m. quadriceps femoris following load carriage. The physiological responses of 10 male participants to voluntary and electrically stimulated isometric contractions were measured before and immediately after two hours of treadmill walking at 6.5 km•h(-1) during level walking with no load [LW], and level walking with load carriage (25 kg backpack) [LC]. Maximal voluntary contraction force decreased by 15 ± 11 % following LC (p=0.006), with no change following LW (p=0.292). Voluntary activation decreased after LW and LC (p=0.033) with no difference between conditions (p=0.405). Doublet contraction time decreased after both LW and LC (p=0.002), with no difference between conditions (p=0.232). There were no other changes in electrically invoked doublet parameters in either condition. The 20:50 Hz ratio did not change following LW (p=0.864) but decreased from 0.88 ± 0.04 to 0.84 ± 0.04 after LC (p=0.011) indicating reduced Ca2+ release from the sarcoplasmic reticulum during excitation contraction coupling. In conclusion, two hours of load carriage carrying a 25 kg back pack caused neuromuscular impairment through a decrease in voluntary activation (i.e. central drive) and fatigue or damage to the peripheral muscle, including impairment of the excitation contraction coupling process. This may reduce physical performance and increase the risk of musculoskeletal injury.

  15. Impaired holistic processing in congenital prosopagnosia.

    It has long been argued that face processing requires disproportionate reliance on holistic or configural processing, relative to that required for non-face object recognition, and that a disruption of such holistic processing may be causally implicated in prosopagnosia. Previously, we demonstrated that individuals with congenital prosopagnosia (CP) did not show the normal face inversion effect (better performance for upright compared to inverted faces) and evinced a local (rather than the normal global) bias in a compound letter global/local (GL) task, supporting the claim of disrupted holistic processing in prosopagnosia. Here, we investigate further the nature of holistic processing impairments in CP, first by confirming, in a large sample of CP individuals, the absence of the normal face inversion effect and the presence of the local bias on the GL task, and, second, by employing the composite face paradigm, often regarded as the gold standard for measuring holistic face processing. In this last task, we show that, in contrast with controls, the CP group perform equivalently with aligned and misaligned faces and was impervious to (the normal) interference from the task-irrelevant bottom part of faces. Interestingly, the extent of the local bias evident in the composite task is correlated with the abnormality of performance on diagnostic face processing tasks. Furthermore, there is a significant correlation between the magnitude of the local bias in the GL and performance on the composite task. These results provide further evidence for impaired holistic processing in CP and, moreover, corroborate the critical role of this type of processing for intact face recognition.

    Almost 30% of humans present a Toxoplasma gondii positive antibody status and its prevalence increases with age. The central nervous system is the main target. However, little is known about the influence of asymptomatic i.e. latent Toxoplasmosis on cognitive functions in humans. To investigate neurocognitive dysfunctions in asymptomatic older adults with T. gondii positive antibody status a double-blinded neuropsychological study was conducted. The participants were classified from a population-based sample (N=131) of healthy participants with an age of 65 years and older into two groups with 42 individuals each: Toxoplasmosis positive (T-pos; IgG>50 IU/ml) and Toxoplasmosis negative (T-neg; IgG=0 IU/ml). The outcome measures were a computer-based working-memory test (2-back) and several standardized psychometric tests of memory and executive cognitive functions. T-pos seniors showed an impairment of different aspects of memory. The rate of correctly detected target symbols in a 2-back task was decreased by nearly 9% (P=0.020), corresponding to a performance reduction of about 35% in working memory relative to the T-neg group. Moreover, T-pos seniors had a lower performance in a verbal memory test, both regarding immediate recall (10% reduction; P=0.022), delayed recognition (6%; P=0.037) and recall from long-term memory assessed by the word fluency tests (12%; P=0.029). In contrast, executive functions were not affected. The effects remained mostly unchanged after controlling for medication. The impairment of memory functions in T-pos seniors was accompanied by a decreased self-reported quality of life. Because of the high prevalence of asymptomatic Toxoplasmosis and an increasing population of older adults this finding is of high relevance for public health.

    Full Text Available Problem statement: The government of Malaysia is considering serious efforts in promoting the usage of computers among disabled people. Currently, the availability of computer applications especially related to creative contents for disabled people in Malaysia is infancy and very expensive. Research and expertise in the area of Assistive Technology (AT in Malaysia is still uncommon and not extensively utilized. Therefore research involving special communities such as disabled people on the usage of electronic applications should be focused because records show that their population populations are increasing. Hence, this research will be tailored for Visually-Impaired (VI learners. In Malaysia, visual impairment is one of the highest registered disabilities. Approach: This study presents an ongoing project that determines whether the VI children can accept the Assistive Courseware (AC as one of the effective tools in their learning process. Specification identification, AC development and testing and evaluation are three activities involved in this study. In addition, data have been collected through qualitative approaches. Results: The results highlight four important elements for incorporated in an AC for VI children. Through the testing and evaluation, it was found that the VI children accept the AC due to interesting usage of audio, graphic, text and easy navigation method. Conclusion: In a nutshell, the positive responses prove that the AC not only exposes the VI children to the world of technology but also educates them in terms of interpersonal skills, intrapersonal skills and motivation. The recommended future work is to produce a much comprehensive AC which focuses on interactivity, various multimedia elements, multiple intelligence elements and multiple stages of exercise in granting value-added AC not only for VI children in Malaysia but also to other world VI communities in the world.

    The School for Young Deaf Children was founded in 1969 when the All India Institute of Speech and Hearing at Mysore and the Christian Medical College Hospital at Vellore started diagnosing hearing impairment in children and prescribing hearing aids. These schools admitted children when they were 5 years old. Bala Vidyalaya was funded as an experimental school to satisfy the needs of younger children. A multi sensory approach based on the Montessori method of teaching with special emphasis on language acquisition was adopted. The School that began with 5 children and 2 teachers had 120 children and 15 teachers in 1992: 50 children were under 3 years old and the rest were between 3 and 6 years. Early auditory management and training is the foundation of the child's linguistic achievement which help the child use the innate ability to develop sophisticated listening skills such as listening to one signal in the presence of competing sounds. Simple games captivate the infants. At the age of 2 1/2 years ideovisual reading is introduced to the child: written sentences are presented to the child about an activity that the child had just experienced. Even before 2 years of age he or she starts scribbling. School lessons are used as tools for writing. The school takes efforts to win the confidence of the parents. So far 97 children have joined the mainstream of education after an initial training the school. Of these, 6 are settled in jobs, 5 are in college or in postgraduate studies, 11 are studying at the university, 8 are in the higher secondary school (classes XI or XII)m 28 are studying in high school (class VI to class X), while the remaining 39 are in primary schools. It has been demonstrated that early educational intervention and involvement of the family into the educational program are very important for the successful integration of hearing-impaired children into the main stream.

    Full Text Available Background: Sensory impairment is a common condition that exerts negative effects on health-related quality of life (HRQoL in the elderly. This study aimed to determine the relationship between sensory impairment and HRQoL and identify sensory-specific differences in the HRQoL of elderly.Methods: This study used data from the Korean National Health and Nutrition Examination Survey V (2010-2012, analyzing 5,260 subjects over 60 years of age who completed ophthalmic and otologic examinations. Vision and hear-ing impairment were measured and classified. HRQoL was determined according to the European QoL five dimen-sion test (EQ-5D. Multivariate logistic regression analysis and analysis of covariance were performed to identify rela-tionships between sensory impairment and HRQoL dimensions as well as differences in HRQoL scores.Results: In the final adjusted multivariate model, there was a statistically higher proportion of those with dual sensory impairment who reported problems with mobility (adjusted odds ratio [aOR] 2.30, 95% confidence interval [CI] 1.45–5.03, usual activities (aOR 2.32, 95% CI 1.16–4.64, and pain/discomfort among EQ-5D subcategories (aOR 1.79, 95% CI 1.07–2.97. In the EQ-5D dimensions, the means and standard deviations of vision impairment (0.86 [0.01] and dual sensory impairment (0.84 [0.02] appeared meaningfully lower than those for no sensory impairment (0.88 [0.00] or hearing impairment (0.88 [0.01]; P = .02.Conclusion: Sensory impairment reduces HRQoL in the elderly. Improvement of HRQoL in the elderly thus requires regular screening and appropriate management of sensory impairment.

    Full Text Available Abstract Background There is little knowledge regarding the prevalence and nature of renal impairment in African populations initiating antiretroviral treatment, nor evidence to inform the most cost effective methods of screening for renal impairment. With the increasing availability of the potentially nephrotixic drug, tenofovir, such information is important for the planning of antiretroviral programmes Methods (i Retrospective review of the prevalence and risk factors for impaired renal function in 2189 individuals initiating antiretroviral treatment in a rural African setting between 2004 and 2007 (ii A prospective study of 149 consecutive patients initiating antiretrovirals to assess the utility of urine analysis for the detection of impaired renal function. Severe renal and moderately impaired renal function were defined as an estimated GFR of ≤ 30 mls/min/1.73 m2 and 30–60 mls/min/1.73 m2 respectively. Logistic regression was used to determine odds ratio (OR of significantly impaired renal function (combining severe and moderate impairment. Co-variates for analysis were age, sex and CD4 count at initiation. Results (i There was a low prevalence of severe renal impairment (29/2189, 1.3% 95% C.I. 0.8–1.8 whereas moderate renal impairment was more frequent (287/2189, 13.1% 95% C.I. 11.6–14.5 with many patients having advanced immunosuppression at treatment initiation (median CD4 120 cells/μl.

    A medical, biophysics, engineering collaboration has produced a standardized cloud-based application for creating automated WPI ratings. The project assigns numerical values to injuries/illness in accordance with the American Medical Association Guides to the Evaluation of Permanent Impairment, Fifth Edition, AMA Press handbook, 5th edition (with 63 medical contributors and 89 medical reviewers). The AMA Guide serves as the industry standard for assigning impairment values for 32 US states and 190 other countries. Clinical medical data is collected using a menu-driven user interface which is computationally combined into a single numeric value. A medical doctor performs a biometric analysis and enters the quantitative data into a mobile device. The data is analyzed using proprietary validation algorithms, and a WPI Impairment rating is created. The findings are imbedded into a formalized medicolegal report in a matter of minutes. This particular presentation will concentrate upon the WPI rating of the spine--cervical, thoracic, and lumbar. Both common rating techniques will be presented--i.e., Diagnosis Related Estimates (DRE) and Range of Motion (ROM).

    Due to the vision-impaired users commonly having difficulty with mobile-phone function operations and adaption any manufacturer's user interface design, the goals for this research are established for evaluating how to improve for them the function operation convenience and user interfaces of either mobile phones or electronic appliances in the market currently. After applying collecting back 30 effective questionnaires from 30 vision-impairment, the comments have been concluded from this research include: (1) All mobile phone manufactures commonly ignorant of the vision-impairment difficulty with operating mobile phone user interfaces; (2) The vision-impairment preferential with audio alert signals; (3) The vision-impairment incapable of mobile-phone procurement independently unless with assistance from others; (4) Preferential with adding touch-usage interface design by the vision-impairment; in contrast with the least requirement for such functions as braille, enlarging keystroke size and diversifying-function control panel. With exploring the vision-impairment's necessary improvements and obstacles for mobile phone interface operation, this research is established with goals for offering reference possibly applied in electronic appliance design and . Hopefully, the analysis results of this research could be used as data references for designing electronic and high-tech products and promoting more usage convenience for those vision-impaired.

    Bora, Emre; Yücel, Murat; Pantelis, Christos

    2010-01-01

    It has recently been suggested that cognitive impairment should be included in the diagnostic criteria of schizophrenia. One of the main arguments in support of this suggestion has been the hope that cognitive impairment can help distinguish schizophrenia from bipolar disorder (BD). However, recent evidence shows that cognitive deficits occur in BD and persist beyond euthymia. Further, mood disorders with psychotic features might be expected to manifest greater cognitive impairment, which further complicates the potential to differentiate these disorders. The goal of the current meta-analysis was to examine the magnitude and characteristics of cognitive impairments in affective psychoses (AP). A systematic search of the existing literature sourced 27 studies that met the inclusion criteria. These studies compared cognitive performances of 763 patients with AP (550 BD and 213 major depressive disorder) and 1823 healthy controls. Meta-regression and subgroup analyses were used to examine the effects of moderator variables. Meta-analyses of these studies showed that patients with AP were impaired in all 15 cognitive tasks with large effect sizes for most measures. There were no significant differences between the magnitude of impairments between the BD and major depressive disorder groups. The largest effect size was found for symbol coding, stroop task, verbal learning, and category fluency, reflecting impairments in elementary and complex aspects of attentional processing, as well as learning and memory. In general, the pattern of cognitive impairments in AP was similar to reported findings in euthymic patients with BD, but relatively more pronounced.

    2009-04-01

    Accurate distance perception depends on the processing and integration of a variety of monocular and binocular cues. Dorsal stream lesions can impair this process, but details of this neurocognitive relationship remain unclear. Here, we tested a patient with bilateral occipitoparietal damage and severely impaired stereopsis. We addressed four related questions: (1) Can distance and size perception survive limitations in perceiving monocular and binocular cues? (2) Are egocentric (self-referential) and allocentric (object-referential) distance judgments similarly impaired? (3) Are distance measurements equally impaired in peripersonal and extrapersonal space? (4) Are size judgments possible when distance processing is impaired? The results demonstrate that the patient's lesions impaired both her distance and size perception, but not uniformly. Her performance when using an egocentric reference frame was more impaired than her performance when using an allocentric reference frame. Likewise, her distance judgments in peripersonal space were more impaired than those in extrapersonal space. The patient showed partial preservation in size processing of novel objects even when familiar size cues were removed.

  16. Physical impairment aware transparent optical networks

    Antona, Jean-Christophe; Morea, Annalisa; Zami, Thierry; Leplingard, Florence

    2009-11-01

    As illustrated by optical fiber and optical amplification, optical telecommunications have appeared for the last ten years as one of the most promising candidates to increase the transmission capacities. More recently, the concept of optical transparency has been investigated and introduced: it consists of the optical routing of Wavelength Division Multiplexed (WDM) channels without systematic optoelectronic processing at nodes, as long as propagation impairments remain acceptable [1]. This allows achieving less power-consuming, more scalable and flexible networks, and today partial optical transparency has become a reality in deployed systems. However, because of the evolution of traffic features, optical networks are facing new challenges such as demand for higher transmitted capacity, further upgradeability, and more automation. Making all these evolutions compliant on the same current network infrastructure with a minimum of upgrades is one of the main issues for equipment vendors and operators. Hence, an automatic and efficient management of the network needs a control plan aware of the expected Quality of Transmission (QoT) of the connections to set-up with respect to numerous parameters such as: the services demanded by the customers in terms of protection/restoration; the modulation rate and format of the connection under test and also of its adjacent WDM channels; the engineering rules of the network elements traversed with an accurate knowledge of the associated physical impairments. Whatever the method and/or the technology used to collect this information, the issue about its accuracy is one of the main concerns of the network system vendors, because an inaccurate knowledge could yield a sub-optimal dimensioning and so additional costs when installing the network in the field. Previous studies [1], [2] illustrated the impact of this knowledge accuracy on the ability to predict the connection feasibility. After describing usual methods to build

    2015-11-01

    Despite the close interrelation between vestibular and visual processing (e.g., vestibulo-ocular reflex), surprisingly little is known about vestibular function in visually impaired people. In this study, we investigated thresholds of passive whole-body motion discrimination (leftward vs. rightward) in nine visually impaired participants and nine age-matched sighted controls. Participants were rotated in yaw, tilted in roll, and translated along the interaural axis at two different frequencies (0.33 and 2 Hz) by means of a motion platform. Superior performance of visually impaired participants was found in the 0.33 Hz roll tilt condition. No differences were observed in the other motion conditions. Roll tilts stimulate the semicircular canals and otoliths simultaneously. The results could thus reflect a specific improvement in canal-otolith integration in the visually impaired and are consistent with the compensatory hypothesis, which implies that the visually impaired are able to compensate the absence of visual input.

    Olfaction and gustation contribute both to the appreciation of food flavours. Although acquired loss of smell has profound consequences on the pleasure of eating, food habits and body weight, less is known about the impact of congenital olfactory impairment on gustatory processing. Here we examined taste identification accuracy and its neural correlates using functional magnetic resonance imaging (fMRI) in 12 congenitally olfactory impaired individuals and 8 normosmic controls. Results showed that taste identification was worse in congenitally olfactory impaired compared to control subjects. The fMRI results demonstrated that olfactory impaired individuals had reduced activation in medial orbitofrontal cortex (mOFC) relative to normosmic subjects while tasting. In addition, olfactory performance as measured with the Sniffin' Sticks correlated positively with taste-induced blood-oxygen-level dependent (BOLD) signal increases in bilateral mOFC and anterior insula. Our data provide a neurological underpinning for the reduced taste perception in congenitally olfactory impaired individuals.

  20. Mild cognitive impairment in Parkinson disease: heterogenous mechanisms.

    Science.gov (United States)

    Jellinger, Kurt A

    2013-01-01

    Cognitive impairment is common in Parkinson disease (PD), with long-term longitudinal studies reporting that most PD patients develop dementia. A high proportion of patients with PD and mild cognitive impairment (MCI) progress to dementia within a short time. Impairments occur in a range of cognitive domains, but single-domain impairment is more common than multiple one, non-amnestic more common than amnestic impairment. Although the term MCI applied to PD (PD-MCI) is not without controversy due to the lack of uniform diagnostic consensus criteria, the biological validity of PD-MCI is supported by many recent studies that show heterogenous mechanisms in the clinical presentation, neuropsychology, neuroimaging, biomarkers, and neuropathology, suggesting abnormal metabolic network activities involving several cortical and subcortical nervous systems. Prospective studies using specific biomarkers, including amyloid imaging, and cerebro-spinal fluid biomarkers are warranted for an exact diagnosis and prognostic assessment of early cognitive deficits in PD patients.

  1. Moderate Hepatic Impairment Does Not Affect Doravirine Pharmacokinetics.

    Doravirine is a novel, potent, nonnucleoside reverse-transcriptase inhibitor currently in development for HIV-1 infection treatment. As a substrate for CYP3A-mediated metabolism, doravirine could potentially be affected by liver-function changes. As a portion of the HIV-1-infected population has varying degrees of liver impairment, we investigated the effect of moderate hepatic impairment on the pharmacokinetic profile and tolerability of single-dose doravirine 100 mg in otherwise healthy subjects. A total of 16 subjects aged 44-64 years took part in the open-label, single-dose trial: 8 with moderate hepatic impairment (Child-Pugh score, 7-9; 6 men, 2 women) and 8 healthy individuals (mean age and height matched with the impairment group; 6 men, 2 women). Subjects with hepatic impairment were required to have chronic, stable hepatic impairment with features of cirrhosis of any etiology. Blood sampling revealed that doravirine exposure was similar in both groups. The observed geometric least-squares mean ratio (90% confidence interval; moderately impaired/healthy subjects) was 0.99 (0.72-1.35) for AUC0-∞ , 0.93 (0.74-1.18) for AUC0-24 h , 0.90 (0.66-1.24) for Cmax , and 0.99 (0.74-1.33) for C24 h . Geometric mean apparent terminal t½ was ∼18 hours for both groups, whereas median Tmax was 2 hours (range, 1-6 hours) and 2.5 hours (range, 1-3 hours) for impaired and healthy individuals, respectively. In addition, doravirine was generally well tolerated. The results demonstrate that moderate hepatic impairment does not have a clinically meaningful effect on doravirine pharmacokinetics. Therefore, dose adjustment should not be necessary in patients with both HIV-1 and moderate hepatic impairment.

    1991-01-01

    Information access via computer terminals extends to blind and low vision persons employed in many technical and nontechnical disciplines. Two aspects are detailed of providing computer technology for persons with a vision related handicap. First, research into the most effective means of integrating existing adaptive technologies into information systems was made. This was conducted to integrate off the shelf products with adaptive equipment for cohesive integrated information processing systems. Details are included that describe the type of functionality required in software to facilitate its incorporation into a speech and/or braille system. The second aspect is research into providing audible and tactile interfaces to graphics based interfaces. Parameters are included for the design and development of the Mercator Project. The project will develop a prototype system for audible access to graphics based interfaces. The system is being built within the public domain architecture of X windows to show that it is possible to provide access to text based applications within a graphical environment. This information will be valuable to suppliers to ADP equipment since new legislation requires manufacturers to provide electronic access to the visually impaired.

  3. Impaired water barrier function in acne vulgaris.

    Yamamoto, A; Takenouchi, K; Ito, M

    1995-01-01

    In acne vulgaris, abnormal follicular keratinization is important for comedo formation, yet the precise mechanisms of comedogenesis are not known. The present study examined the interrelationship between sebum secretion rate (SSR), lipid content and water barrier function (WBF) of the stratum corneum (SC) in 36 acne patients and 29 control subjects. All major SC lipid classes were separated and quantified by thin-layer chromatography/photodensitometry. WBF was evaluated by measuring transepidermal water loss (TEWL), and the hygroscopic properties and waterholding capacity of the SC. The SSR over a period of 3 h was significantly higher in patients with moderate acne than in control subjects, but no significant difference was noticed between patients with mild acne and control subjects. Significant differences between patients with both moderate and mild acne and control subjects were noted in the amount of sphingolipids (ceramides and free sphingosine), but not for any other lipid classes. Furthermore in acne patients, lower amounts of sphingolipids were observed corresponding with a diminished WBF. These results suggest that an impaired WBF caused by decreased amounts of ceramides may be responsible for comedo formation, since barrier dysfunction is accompanied by hyperkeratosis of the follicular epithelium.

  4. Ocean acidification impairs crab foraging behaviour.

    Anthropogenic elevation of atmospheric CO2 is driving global-scale ocean acidification, which consequently influences calcification rates of many marine invertebrates and potentially alters their susceptibility to predation. Ocean acidification may also impair an organism's ability to process environmental and biological cues. These counteracting impacts make it challenging to predict how acidification will alter species interactions and community structure. To examine effects of acidification on consumptive and behavioural interactions between mud crabs (Panopeus herbstii) and oysters (Crassostrea virginica), oysters were reared with and without caged crabs for 71 days at three pCO2 levels. During subsequent predation trials, acidification reduced prey consumption, handling time and duration of unsuccessful predation attempt. These negative effects of ocean acidification on crab foraging behaviour more than offset any benefit to crabs resulting from a reduction in the net rate of oyster calcification. These findings reveal that efforts to evaluate how acidification will alter marine food webs should include quantifying impacts on both calcification rates and animal behaviour.

  5. Learning under stress impairs memory formation.

    Science.gov (United States)

    Schwabe, Lars; Wolf, Oliver T

    2010-02-01

    Converging lines of evidence indicate that stress either before or after learning influences memory. Surprisingly little is known about how memory is affected when people learn while they are stressed. Here, we examined the impact of learning under stress in 48 healthy young men and women. Participants were exposed to stress (socially evaluated cold pressor test) or a control condition while they learned emotional words and neutral words that were either conceptually associated with or unrelated to the stressor. Memory was assessed in free recall and recognition tests 24h after learning. Learning under stress reduced both free recall and recognition performance, irrespective of the emotionality and the stress context relatedness of the words. While the effect of stress was comparable in men and women, women outperformed men in the free recall test. These findings show a memory impairing effect of learning under stress in humans and challenge some assumptions of current theories about the impact of stress around the time of learning on memory formation.

    1986-12-01

    The olfactory perception of 20 men (tank cleaners) exposed to petroleum products (while cleaning oil tanks) was examined. Office workers and watchmen were used as referents (N = 20 + 20). They were matched with regard to sex, age, and smoking habits. Odor detection thresholds and the perceived odor intensity of four odorous stimuli, pyridine, dimethyl disulfide (DMDS), n-butanol, and heating oil vapor (gas phase of heating oil heated to +40 degrees C), were determined. The results suggested that the tank cleaners had higher absolute odor thresholds for n-butanol and oil vapor than the referents. The psychophysical function of the tank cleaners and referents differed for all the tested substances in respect to odor intensity. The tank cleaners displayed an odor deficit analogous to the hearing loss known as "loudness recruitment," ie, normal perception of strong stimuli but impaired perception of weak stimuli. This odor deficit was therefore named "odor intensity recruitment" and seems, in tank cleaners, to be associated with occupational exposure to oil vapor.

  7. NCOA4 Deficiency Impairs Systemic Iron Homeostasis

    Directory of Open Access Journals (Sweden)

    Roberto Bellelli

    2016-01-01

    Full Text Available The cargo receptor NCOA4 mediates autophagic ferritin degradation. Here we show that NCOA4 deficiency in a knockout mouse model causes iron accumulation in the liver and spleen, increased levels of transferrin saturation, serum ferritin, and liver hepcidin, and decreased levels of duodenal ferroportin. Despite signs of iron overload, NCOA4-null mice had mild microcytic hypochromic anemia. Under an iron-deprived diet (2–3 mg/kg, mice failed to release iron from ferritin storage and developed severe microcytic hypochromic anemia and ineffective erythropoiesis associated with increased erythropoietin levels. When fed an iron-enriched diet (2 g/kg, mice died prematurely and showed signs of liver damage. Ferritin accumulated in primary embryonic fibroblasts from NCOA4-null mice consequent to impaired autophagic targeting. Adoptive expression of the NCOA4 COOH terminus (aa 239–614 restored this function. In conclusion, NCOA4 prevents iron accumulation and ensures efficient erythropoiesis, playing a central role in balancing iron levels in vivo.

  8. Impaired glucose tolerance in sleep disorders.

    Marietta Keckeis

    Full Text Available BACKGROUND: Recent epidemiological and experimental data suggest a negative influence of shortened or disturbed night sleep on glucose tolerance. Due to the high prevalence of sleep disorders this might be a major health issue. However, no comparative studies of carbohydrate metabolism have been conducted in clinical sleep disorders. METHODOLOGY/PRINCIPAL FINDINGS: We performed oral glucose tolerance tests (OGTT and assessed additional parameters of carbohydrate metabolism in patients suffering from obstructive sleep apnea syndrome (OSAS, N = 25, restless legs syndrome (RLS, N = 18 or primary insomnia (N = 21, and in healthy controls (N = 33. Compared to controls, increased rates of impaired glucose tolerance were found in OSAS (OR: 4.9 and RLS (OR: 4.7 patients, but not in primary insomnia patients (OR: 1.6. In addition, HbA1c values were significantly increased in the same two patient groups. Significant positive correlations were found between 2-h plasma glucose values measured during the OGTT and the apnea-arousal-index in OSAS (r = 0.56; p<0.05 and the periodic leg movement-arousal-index in RLS (r = 0.56, p<0.05, respectively. Sleep duration and other quantitative aspects of sleep were similar between patient groups. CONCLUSIONS/SIGNIFICANCE: Our findings suggest that some, but not all sleep disorders considerably compromise glucose metabolism. Repeated arousals during sleep might be a pivotal causative factor deserving further experimental investigations to reveal potential novel targets for the prevention of metabolic diseases.

    Full Text Available Background: Psoriasis is a chronic disease, the course of which is punctuated by exacerbations and remissions. The impact of a chronic, relapsing, and disfiguring disease such as psoriasis on occupational, social, and other areas of functioning is substantial and needs attention. Aim: The purpose of this study was to assess the level and nature of functional impairment in psoriasis. Methods: Forty-three consecutive patients attending the dermatology clinic of a rural hospital were studied for psychiatric comorbidity and the level of functioning, using a semistructured questionnaire. Results: Psoriasis affected social functioning of 48% patients, led to decreased work efficiency in 51.1%, and to subjective distress at work in 62.8% of patients. Stress in home environment and interpersonal relationships was reported by 69.8%. Social and occupational functioning worsened with increasing severity of psoriasis after 1-year duration of illness. Patients complaining of pruritis frequently had anxiety disorders. Psychiatric comorbidity was detected in 67.4% cases. Conclusion : Substantial proportion of patients suffered deterioration of functioning, especially with increasing duration of illness. Thus, timely attention by dermatologists is needed in order to limit the disability caused by psoriasis. To achieve this, liaison with psychiatrist would be crucial along with illness education and emotional support.

  10. Low molecular weight heparin impairs tendon repair.

    Virchenko, O; Aspenberg, P; Lindahl, T L

    2008-03-01

    Thrombin has many biological properties similar to those of growth factors. In a previous study, we showed that thrombin improves healing of the rat tendo Achillis. Low molecular weight heparin (LMWH) inhibits the activity and the generation of thrombin. We therefore considered that LMWH at a thromboprophylactic dose might inhibit tendon repair. Transection of the tendo Achillis was carried out in 86 rats and the healing tested mechanically. Low molecular weight heparin (dalateparin) was either injected a few minutes before the operation and then given continuously with an osmotic mini pump for seven days, or given as one injection before the operation. In another experiment ,we gave LMWH or a placebo by injection twice daily. The anti-factor Xa activity was analysed. Continuous treatment with LMWH impaired tendon healing. After seven days, this treatment caused a 33% reduction in force at failure, a 20% reduction in stiffness and a 67% reduction in energy uptake. However, if injected twice daily, LMWH had no effect on tendon healing. Anti-factor Xa activity was increased by LMWH treatment, but was normal between intermittent injections. Low molecular weight heparin delays tendon repair if given continuously, but not if injected intermittently, probably because the anti-factor Xa activity between injections returns to normal, allowing sufficient thrombin stimulation for repair. These findings indicate the need for caution in the assessment of long-acting thrombin and factor Xa inhibitors.

    Full Text Available Impaired fracture healing can occur in severely injured patients with hemorrhagic shock due to decreased soft tissue perfusion after trauma. We investigated the effects of fracture healing in a standardized pressure controlled hemorrhagic shock model in mice, to test the hypothesis that bleeding is relevant in the bone healing response. Male C57/BL6 mice were subjected to a closed femoral shaft fracture stabilized by intramedullary nailing. One group was additionally subjected to pressure controlled hemorrhagic shock (HS, mean arterial pressure (MAP of 35 mmHg for 90 minutes. Serum cytokines (IL-6, KC, MCP-1, and TNF-α were analyzed 6 hours after shock. Fracture healing was assessed 21 days after fracture. Hemorrhagic shock is associated with a significant increase in serum inflammatory cytokines in the early phase. Histologic analysis demonstrated a significantly decreased number of osteoclasts, a decrease in bone quality, and more cartilage islands after hemorrhagic shock. μCT analysis showed a trend towards decreased bone tissue mineral density in the HS group. Mechanical testing revealed no difference in tensile failure. Our results suggest a delay in fracture healing after hemorrhagic shock. This may be due to significantly diminished osteoclast recruitment. The exact mechanisms should be studied further, particularly during earlier stages of fracture healing.

    Full Text Available Economic recession has led to the worsening of financial results of many Lat-vian companies. In this situation, cash flows from the use of assets in economic activities turn out to be insufficient to recover the balance sheet value of those as-sets. The laws and accounting standards of Latvia do not provide sufficient guid-ance on how the decrease in value should be calculated because cash flows gener-ated by individual items of fixed assets cannot be estimated reliably in most cases. In the present economic situation it seems reasonable to follow the rule that when the market value of assets is lower than their balance sheet value it is necessary to recognize an impairment loss or to carry out their revaluation, which will allow their true value to be calculated. Annual revaluation is necessary for those items whose true value is changeable. For items whose values change rarely revaluation can be done less frequently. In the economic situation of Latvia almost every com-pany, excepting only some production areas, is facing a high risk of decrease in the value of its assets. If there are indications that there may be a decrease in the value of long term assets, the company’s management has to consider at least the indicators provided by internal and external sources of information.

    The estimated 3.7 million Americans with low vision experience a uniquely difficult task in identifying the denominations of U.S. banknotes because the notes are remarkably uniform in size, color, and general design. The National Research Council's Committee on Currency Features Usable by the Visually Impaired assessed features that could be used by people who are visually disabled to distinguish currency from other documents and to denominate and authenticate banknotes using available technology. Variation of length and height, introduction of large numerals on a uniform, high-contrast background, use of different colors for each of the six denominations printed, and the introduction of overt denomination codes that could lead to development of effective, low-cost devices for examining banknotes were all deemed features available now. Issues affecting performance, including the science of visual and tactile perception, were addressed for these features, as well as for those features requiring additional research and development. In this group the committee included durable tactile features such as those printed with transparent ink, and the production of currency with holes to indicate denomination. Among long-range approaches considered were the development of technologically advanced devices and smart money.

    The recently adopted UN Convention on the Rights of Persons with Disabilities acknowledges the need to address social exclusion and poverty of persons with disabilities. However, policy makers, especially in low-income countries, often lack information about the socioeconomic situation of this vulnerable group of society. This study aimed to assess the association between poverty and musculoskeletal impairment (MSI) in Rwanda. A nationwide population-based matched case-control study was undertaken in Rwanda. Data were collected on education, literacy, employment, household expenditure and assets for 345 cases and 532 matched controls. Conditional logistic regression was performed, and the results indicated that adults with MSI in Rwanda are more likely to have no employment (odds ratio (OR)=3.3, 95% CI 2.1-5.2) while children with MSI are less likely to attend school (OR=0.4, 95% CI 0.2-0.9). Cases with MSI are disadvantaged vis-à-vis housing conditions and household size, potentially indicating crowding. However, cases with MSI were not poorer than controls in terms of assets or expenditure. These data suggest that increased efforts should be undertaken in Rwanda in order to ensure that children with disabilities are included in schools and that adults with disabilities can find appropriate employment opportunities.

    Mycobacterium avium ssp. paratuberculosis (MAP) causes Johne's disease, a chronic, granulomatous enteritis of ruminants. Dendritic cells (DC) of the gut are ideally placed to combat invading mycobacteria; however, little is known about their interaction with MAP. Here, we investigated the interaction of MAP and the closely related M. avium ssp. avium (MAA) with murine DC and the effect of infected macrophages on DC maturation. The infection of DC with MAP or MAA induced DC maturation, which differed to that of LPS as maturation was accompanied by higher production of IL-10 and lower production of IL-12. Treatment of maturing DC with supernatants from mycobacteria-infected macrophages resulted in impaired DC maturation, leading to a semi-mature, tolerogenic DC phenotype expressing low levels of MHCII, CD86 and TNF-α after LPS stimulation. Though the cells were not completely differentiated they responded with an increased IL-10 and a decreased IL-12 production. Using recombinant cytokines we provide evidence that the semi-mature DC phenotype results from a combination of secreted cytokines and released antigenic mycobacterial components of the infected macrophage. Our results indicate that MAP and MAA are able to subvert DC function directly by infecting and indirectly via the milieu created by infected macrophages.

    Although chemicals posing potential neurotoxic hazards are commonly used in the microelectronics industry, there has been no systematic study of possible chronic nervous system effects in microelectronics workers. The objective of the present study was to assess neuropsychological functions of a group of former microelectronics plant assembly workers and a group of referents, using a matched pair design. During employment, the former microelectronics workers had been exposed to multiple organic solvents, including trichloroethylene, xylene, chlorofluorocarbons and trichloroethane. Referents were recruited from the same geographic region. From a pool of 180 former workers and 157 referents, 67 pairs were matched on the basis of age, sex, ethnicity, educational level, sex and number of children. Comparison of results on the subtests of the California Neuropsychological Screening Battery-Revised (CNS-R) revealed significantly lower performance by the former microelectronics workers on tests of attention/concentration, verbal ability, memory functions, visuospatial functions, visuomotor speed, cognitive flexibility, psychomotor speed, and reaction time (t-test for pairs or Wilcoxon Signed Rank p less than 0.05). No significant differences were observed for performance on tests assessing mental status, visual recall, tactile function and learning. This overall pattern of impairment is consistent with organic solvent-related chronic toxic encephalopathy, and possible early stages of dementia. These findings underline the need for more studies among workers currently or previously employed in microelectronics industries.

    We aimed to categorize subjective memory impairment (SMI) individuals based on their patterns of cortical thickness and to propose simple models that can classify each subtype. We recruited 613 SMI individuals and 613 age- and gender-matched normal controls. Using hierarchical agglomerative cluster analysis, SMI individuals were divided into 3 subtypes: temporal atrophy (12.9%), minimal atrophy (52.4%), and diffuse atrophy (34.6%). Individuals in the temporal atrophy (Alzheimer's disease-like atrophy) subtype were older, had more vascular risk factors, and scored the lowest on neuropsychological tests. Combination of these factors classified the temporal atrophy subtype with 73.2% accuracy. On the other hand, individuals with the minimal atrophy (non-neurodegenerative) subtype were younger, were more likely to be female, and had depression. Combination of these factors discriminated the minimal atrophy subtype with 76.0% accuracy. We suggest that SMI can be largely categorized into 3 anatomical subtypes that have distinct clinical features. Our models may help physicians decide next steps when encountering SMI patients and may also be used in clinical trials.

    Masaya Ito

    Full Text Available The Overall Depression Severity and Impairment Scale (ODSIS is a brief, five-item measure for assessing the frequency and intensity of depressive symptoms, as well as functional impairments in pleasurable activities, work or school, and interpersonal relationships due to depression. Although this scale is expected to be useful in various psychiatric and mental health settings, the reliability, validity, and interpretability have not yet been fully examined. This study was designed to examine the reliability, factorial, convergent, and discriminant validity of a Japanese version of the ODSIS, as well as its ability to distinguish between individuals with and without a major depressive disorder diagnosis.From a pool of registrants at an internet survey company, 2830 non-clinical and clinical participants were selected randomly (619 with major depressive disorder, 619 with panic disorder, 576 with social anxiety disorder, 645 with obsessive-compulsive disorder, and 371 non-clinical panelists. Participants were asked to respond to the ODSIS and conventional measures of depression, functional impairment, anxiety, neuroticism, satisfaction with life, and emotion regulation.Exploratory and confirmatory factor analysis of three split subsamples indicated the unidimensional factor structure of ODSIS. Multi-group confirmatory factor analysis showed invariance of factor loadings between non-clinical and clinical subsamples. The ODSIS also showed excellent internal consistency and test-retest intraclass correlation coefficients. Convergence and discriminance of the ODSIS with various measures were in line with our expectations. Receiver operating characteristic curve analyses showed that the ODSIS was able to detect a major depressive syndrome accurately.This study supports the reliability and validity of ODSIS in a non-western population, which can be interpreted as demonstrating cross-cultural validity.

    Cortical/cerebral visual impairment (CVI) is clinically defined as significant visual dysfunction caused by injury to visual pathways and structures occurring during early perinatal development. Depending on the location and extent of damage, children with CVI often present with a myriad of visual deficits including decreased visual acuity and impaired visual field function. Most striking, however, are impairments in visual processing and attention which have a significant impact on learning, development, and independence. Within the educational arena, current evidence suggests that strategies designed for individuals with ocular visual impairment are not effective in the case of CVI. We propose that this variance may be related to differences in compensatory neuroplasticity related to the type of visual impairment, as well as underlying alterations in brain structural connectivity. We discuss the etiology and nature of visual impairments related to CVI, and how advanced neuroimaging techniques (i.e., diffusion-based imaging) may help uncover differences between ocular and cerebral causes of visual dysfunction. Revealing these differences may help in developing future strategies for the education and rehabilitation of individuals living with visual impairment.

    BACKGROUND: Cognitive impairment after stroke associates with various factors, such as age, educational years, etc. Besides concerning about the recovery of limb function after stroke, we should also focus on the rehabilitation of cognition. Moreover, we'd better pay attention to the control of all the risk factors of stroke, and improve the quality of life in stroke patients.OBJECTIVE: To analyze the factors that affect cognitive impairment after stroke.DESIGN: A related factors analysis.SET-FINGS: Department of Neurology of Dalian Port Hospital and Dalian Second People's Hospital.PARTICIPANTS: Totally 148 stroke inpatients were selected from Department of Neurology, Dalian Port Hospital and Dalian Second People's Hospital from April 2004 to December 2005, including 100 males and 48females, aging 45-75 years with an average age of (67±8) years; Their educational years ranged 2-10 years with an average of (6.1 ±3.7) years; The disease course ranged 15-30 days; All were right-handed. Inclusive criteria: All were accorded with the diagnostic standard set by the Fourth National Academic Meeting for Cerebrovascular Disease; Confirmed by CT or MRI; Informed consents were obtained from all the subjects.METHODS: After the disease conditions were stable, the patients were assessed with Wechsler memory scale (WMS) and Wisconsin card sorting test (WCST). WMS included forward and backward recitation of numbers and short-term memory (verbal memory, visual recognition). The number of times for correct and wrong classifications in WCST and the time to complete the trail making tests A and B were recorded. The focal volume, area and layer were recorded at 24 hours after admission. The general data of the patients were recorded, including name, sex, age, educational years, history of hypertension, history of diabetes mellitus.Electroencepalograph (EEC) was examined to record the wave shape, blood lipids were detected, and the cognition related indexes were analyzed with the

    Full Text Available Consuelo H Wilkins1,2, Jose Mathews2, Yvette I Sheline21Department of Medicine (Division of Geriatrics and Nutritional Science; 2Department of Psychiatry, Washington University School of Medicine, St. Louis, MO, USAAbstract: Older adults with depression often present with signs and symptoms indicative of functional or cognitive impairment. These somatic symptoms make evaluating and treating depression in older adults more complex. Late life depression (LLD, depression in adults over the age of 65, is more frequently associated with cognitive changes. Cognitive impairment in LLD may be a result of the depressive disorder or an underlying dementing condition. Memory complaints are also common in older adults with depression. There is a wide range of cognitive impairment in LLD including decreased central processing speed, executive dysfunction, and impaired short-term memory. The etiology of cognitive impairment in LLD may include cerebrovascular disease, a significant risk factor for LLD, which likely interrupts key pathways between frontal white matter and subcortical structures important in mood regulation. Because depressive symptoms often coexist with dementia, it is important to determine the temporal relationship between depressive symptoms and cognitive change. If depressive symptoms pre-date the cognitive impairment and cognitive symptoms are mild and temporary, LLD is the likely etiology of the cognitive impairment. If cognitive changes appear prior to depressive symptoms and persist after LLD is successfully treated, an underlying dementia is more likely. Clinicians should be exclude common conditions such as thyroid disease which can contribute to depressive symptoms and cognitive impairment prior to treating LLD. Both antidepressants and psychotherapy can be effective in treating LLD. Subsequent evaluations following treatment should also reassess cognition.Keywords: late life depression, cognitive impairment, diagnosis, treatment

    2017-01-01

    Purpose Conivaptan is an intravenous dual V1A/V2 vasopressin antagonist approved for the treatment of euvolemic and hypervolemic hyponatremia. Earlier studies showed that patients with moderate liver disease could be safely treated with conivaptan by reducing the dose by 50%, whereas patients with mild hepatic impairment needed no dose adjustment. The objective of this Phase 1, open-label study was to assess the pharmacokinetics, protein binding, and safety of 48 h of conivaptan infusion in individuals with severe hepatic impairment. Patients and methods Eight subjects with severe hepatic impairment (Child–Pugh score 10–15) and nine subjects with normal liver function were enrolled. Intravenous conivaptan (20 mg) was given as a 30 min loading dose on Day 1 followed by two consecutive 20 mg continuous infusions over 24 h each. Subjects were monitored for adverse events and changes in clinical laboratory parameters. Plasma and urine pharmacokinetic samples were collected at defined times. Subjects were followed through Study Day 5. Results Hepatically impaired individuals exhibited higher concentrations of plasma conivaptan throughout the treatment period. Overall exposure, as measured by area under the plasma conivaptan concentration-time curve from time zero through infinity (AUCINF), was ~60% higher in impaired individuals compared to those with normal liver function. Terminal elimination half-life was slightly longer in impaired subjects (12 h) as compared to normal subjects (9 h), and clearance was 65% higher in subjects with normal liver function, while urinary excretion was higher in impaired individuals. Albumin levels directly, and alkaline phosphatase inversely, correlated with conivaptan clearance. Conclusion A 20 mg conivaptan loading dose given >30 min followed by two daily infusions of 20 mg each was well tolerated by patients with severe hepatic impairment as monitored by adverse events and clinical laboratory values. Based on pharmacokinetic data

    Background Both language and music are thought to have evolved from a musical protolanguage that communicated social information, including emotion. Individuals with perceptual music disorders (amusia) show deficits in auditory emotion recognition (AER). Although auditory perceptual deficits have been studied in schizophrenia, their relationship with musical/protolinguistic competence has not previously been assessed. Method Musical ability was assessed in 31 schizophrenia/schizo-affective patients and 44 healthy controls using the Montreal Battery for Evaluation of Amusia (MBEA). AER was assessed using a novel battery in which actors provided portrayals of five separate emotions. The Disorganization factor of the Positive and Negative Syndrome Scale (PANSS) was used as a proxy for language/thought disorder and the MATRICS Consensus Cognitive Battery (MCCB) was used to assess cognition. Results Highly significant deficits were seen between patients and controls across auditory tasks (p<0.001). Moreover, significant differences were seen in AER between the amusia and intact music-perceiving groups, which remained significant after controlling for group status and education. Correlations with AER were specific to the melody domain, and correlations between protolanguage (melody domain) and language were independent of overall cognition. Discussion This is the first study to document a specific relationship between amusia, AER and thought disorder, suggesting a shared linguistic/protolinguistic impairment. Once amusia was considered, other cognitive factors were no longer significant predictors of AER, suggesting that musical ability in general and melodic discrimination ability in particular may be crucial targets for treatment development and cognitive remediation in schizophrenia.

    Several studies suggest that the disorders of the self include a disturbance of the most elementary component of self - the minimal self. Characterizing these disorders and understanding the mechanisms involved remain a challenge to medical epistemology and health care professionals. In the present work, I bring together concepts of different fields, such as neuroscience, epistemology and phenomenology. The main goal is to show that the second-person perspective can be used to point out particular features of social cognition and its related psychopathology. Taking the hypothesis that the second-person perspective is the congruence point between an objective process and the subjective experience, I will attempt to explain schizophrenia as a self-related deficit, first in the light of the first-person and the third-person perspective and afterward, in the light of the poorly less understood second-person perspective. On the one hand, the first-person experience is correlated both with space and time. In fact, psychiatric patients report subjective experiences that can be understood within research on the bodily self, such as (1) spatially incongruent proprioception and (2) impaired sense of time as the basic mechanism that allows conscious experience. On the other hand, the second-person approach has already begun to prove productive within social cognition research, pointing out the importance of experiencing and interacting with others as our primarily way well-being. I will phenomenological analyse subjective and intersubjective experience in the disorders of the self and derive practical consequences to evidence-based medicine.

  6. Modeling Impaired Hippocampal Neurogenesis after Radiation Exposure.

    Radiation impairment of neurogenesis in the hippocampal dentate gyrus is one of several factors associated with cognitive detriments after treatment of brain cancers in children and adults with radiation therapy. Mouse models have been used to study radiation-induced changes in neurogenesis, however the models are limited in the number of doses, dose fractions, age and time after exposure conditions that have been studied. The purpose of this study is to develop a novel predictive mathematical model of radiation-induced changes to neurogenesis using a system of nonlinear ordinary differential equations (ODEs) to represent the time, age and dose-dependent changes to several cell populations participating in neurogenesis as reported in mouse experiments exposed to low-LET radiation. We considered four compartments to model hippocampal neurogenesis and, consequently, the effects of radiation treatment in altering neurogenesis: (1) neural stem cells (NSCs), (2) neuronal progenitor cells or neuroblasts (NB), (3) immature neurons (ImN) and (4) glioblasts (GB). Because neurogenesis is decreasing with increasing mouse age, a description of the age-related dynamics of hippocampal neurogenesis is considered in the model, which is shown to be an important factor in comparisons to experimental data. A key feature of the model is the description of negative feedback regulation on early and late neuronal proliferation after radiation exposure. The model is augmented with parametric descriptions of the dose and time after irradiation dependences of activation of microglial cells and a possible shift of NSC proliferation from neurogenesis to gliogenesis reported at higher doses (∼10 Gy). Predictions for dose-fractionation regimes and for different mouse ages, and prospects for future work are then discussed.

    Alódia Brasil

    Full Text Available Alcohol consumption among young adults is widely accepted in modern society and may be the starting point for abusive use of alcohol at later stages of life. Chronic alcohol exposure can lead to visual function impairment. In the present study, we investigated the spatial luminance contrast sensitivity, colour arrangement ability, and colour discrimination thresholds on young adults that weekly consume alcoholic beverages without clinical concerns. Twenty-four young adults were evaluated by an ophthalmologist and performed three psychophysical tests to evaluate their vision functions. We estimated the spatial luminance contrast sensitivity function at 11 spatial frequencies ranging from 0.1 to 30 cycles/degree. No difference in contrast sensitivity was observed comparing alcohol consumers and control subjects. For the evaluation of colour vision, we used the Farnsworth-Munsell 100 hue test (FM 100 test to test subject's ability to perform a colour arrangement task and the Mollon-Reffin test (MR test to measure subject's colour discrimination thresholds. Alcohol consumers made more mistakes than controls in the FM100 test, and their mistakes were diffusely distributed in the FM colour space without any colour axis preference. Alcohol consumers also performed worse than controls in the MR test and had higher colour discrimination thresholds compared to controls around three different reference points of a perceptually homogeneous colour space, the CIE 1976 chromaticity diagram. There was no colour axis preference in the threshold elevation observed among alcoholic subjects. Young adult weekly alcohol consumers showed subclinical colour vision losses with preservation of spatial luminance contrast sensitivity. Adolescence and young adult age are periods of important neurological development and alcohol exposure during this period of life might be responsible for deficits in visual functions, especially colour vision that is very sensitive to

    2010-01-01

    Since 2006 there have been 6 reported cases of altered visual acuity and intracranial pressure (ICP) in long duration astronauts. In order to document this risk and develop an integrated approach to its mitigation, the NASA Space Life Sciences Directorate (SLSD) and Human Research Program (HRP) have chosen to use the Human System Risk Board (HSRB) and the risk management analysis tool (RMAT). The HSRB is the venue in which the stakeholders and customers discuss and vet the evidence and the RMAT is the tool that facilitates documentation and comparison of the evidence across mission profiles as well as identification of risk factors, and documentation of mitigation strategies. This process allows for information to be brought forward and dispositioned so that it may be properly incorporated into the RMAT and contribute to the design of the research and mitigation plans. The evidence thus far has resulted in the identification of a visual impairment/intracranial pressure (VIIP) project team, updating of both short and long duration medical requirements designed to assess visual acuity, and a research plan to characterize this issue further. In order to understand this issue more completely, a plan to develop an Accelerated Research Collaboration (ARC) has been approved by the HSRB. The ARC is a novel research model pioneered by the Myelin Repair Foundation. It is a patient centered research model that brings together researchers and clinicians, under the guidance of a scientific advisory panel, to collaborate and produce results much quickly than accomplished through traditional research models. The data and evidence from the updated medical requirements and the VIIP ARC will be reviewed at the HSRB on a regular basis. Each review package presented to the HSRB will include an assessment and recommendation with respect to continuation of research, countermeasure development, occupational surveillance modalities, selection criteria, etc. This process will determine the

    Specific Language Impairment (SLI), as many other cognitive deficits, is difficult to diagnose given its heterogeneous profile and its overlap with other impairments. Existing techniques are based on different criteria using behavioral variables on different tasks. In this paper we propose a methodology for the diagnosis of SLI that uses computational cognitive modeling in order to capture the internal mechanisms of the normal and impaired brain. We show that machine learning techniques that use the information of these models perform better than those that only use behavioral variables.

The aim of this study was to compare different aspects of memory complaints (i.e., prospective versus retrospective complaints) in individuals with subjective cognitive impairment (SCI), amnestic mild cognitive impairment (aMCI), and mild Alzheimer's disease (AD). The study included a total of 115 participants (mean age: 68.82 ± 8.83 years) with SCI (n = 34), aMCI (n = 46), and mild AD (n = 35). Memory complaints were assessed using the Prospective and Retrospective Memory Questionnaire (PRMQ), which consists of 16 items that describe everyday memory failure of both prospective memory (PM) and retrospective memory (RM). For aMCI and AD subjects, informants also completed an informant-rating of the PRMQ. All participants completed detailed neuropsychological tests. Results show that PM complaints were equivalent among the three groups. However, RM complaints differed. Specifically, RM complaints in aMCI were higher than SCI, but similar to AD. Informant-reported memory complaints were higher for AD than aMCI. Our study suggests that RM complaints of memory complaints may be helpful in discriminating between SCI and aMCI, but both PM and RM complaints are of limited value in differentiating aMCI from AD.

    Parkinson's disease (PD) patients show marked impairments in processing action verbs, and to a lesser extent, concrete (specially, manipulable) nouns. However, it is still unclear to what extent deficits in each of these categories are influenced by more general cognitive dysfunctions, and whether they are modulated by the words' implied motility. To examine these issues, we evaluated 49 non-demented PD patients and 49 healthy volunteers in an oral production task. The patients were divided into two groups depending on the presence or absence of mild cognitive impairment (PD-MCI and PD-nMCI, respectively). Participants named pictures of actions varying in motion content (low and high) and of objects varying in manipulability (low and high). The PD-MCI group showed deficits across all four categories. However, PD-nMCI patients exhibited a selective difficulty for high-motion action verbs. This finding corroborates and refines previous results suggesting that disturbances of action-related lexico-semantic information in PD constitute a sui generis alteration manifested early in the course of the disease's physiopathology. Moreover, it suggests that the grounding of action verbs on motor circuits could depend on fine-grained intracategorical semantic distinctions.

    Full Text Available The paper represents the architecture and implementation of a system that will help to navigate the visually impaired people. The system designed uses GPS and voice recognition along with obstacle avoidance for the purpose of guiding visually impaired. The visually impaired person issues the command and receives the direction response using audio signals. The latitude and longitude values are received continuously from the GPS receiver. The directions are given to the user with the help of audio signals. An obstacle detector is used to help the user to avoid obstacles by sending an audio message.GPS receivers use NMEA standard. With the advancement in voice recognition it becomes easier to issue commands regarding directions to the visually impaired.

    This article presents a diagnosis of luxury or superior hotels in the city of Natal, located in the state of Rio Grande do Norte, in northeastern Brazil, in what concerns accessibility to the visually impaired. The main objective is to present the guiding principles to design actions and interventions that must be considered in the preparation or revision of technical standards and manuals of good practice in accessibility related to people with visual impairments who are hotel users. The survey showed that the hotels do not meet the normative indications of accessibility, their facilities are in-accessible (have prevented access) or of reduced accessibility and its employees are not prepared to provide adequate hospital services for people with visual impairment. It was concluded that some of the accessibility problems faced by people with visual impairments are also faced by people in general.

    Full Text Available Introduction. A family history of Alzheimer’s disease is a significant risk factor for its onset, but the genetic risk associated with possessing multiple risk alleles is still poorly understood. Methods. In a sample of 95 older adults (Mean age = 75.1, 64.2% female, we constructed a genetic risk score based on the accumulation of risk alleles in BDNF, COMT, and APOE. A neuropsychological evaluation and consensus determined cognitive status (44 nonimpaired, 51 impaired. Logistic regression was performed to determine whether the genetic risk score predicted cognitive impairment above and beyond that associated with each gene. Results. An increased genetic risk score was associated with a nearly 4-fold increased risk of cognitive impairment (OR = 3.824, P = .013 when including the individual gene polymorphisms as covariates in the model. Discussion. A risk score combining multiple genetic influences may be more useful in predicting late-life cognitive impairment than individual polymorphisms.

  20. Impairment of Methotrexate Transport Is Common in Osteosarcoma Tumor Samples

    Full Text Available Osteosarcoma does not respond well to conventional dose methotrexate but does respond to high-dose methotrexate. Previous work has indicated that this resistance may be due to impaired transport of methotrexate across the cell membrane. In this study, the PT430 competitive displacement assay was adapted to evaluate methotrexate transport in 69 high-grade osteosarcoma tumor samples. All samples studied were shown to have relatively impaired methotrexate transport by PT430 assay. Ninety-nine percent of the samples had less than 20% PT430 displacement by methotrexate. Eighty-eight percent exhibited displacement by methotrexate at less than 50% of the displacement by trimetrexate. The high frequency of impaired transport suggests the presence of decreased functionality of the reduced folate carrier protein. The overwhelming presence of impaired transport may explain why methotrexate needs to be given in high doses to be effective in osteosarcoma therapy and suggests that reduced folate carrier-independent antifolates should be explored.
