    This study determined the effects of procedures designed to "enrich" the physical and social environment of an institutional ward on the "adaptive" and "maladaptive" child, adult, self, and object-directed behaviors of five profoundly retarded ambulatory females. Behavior observed in two treatment conditions, an environment "enriched" with toys and objects and an "enriched" environment coupled with differential reinforcement of adaptive behavior, was compared to behavior occurring in correspo...

  2. Acquisition and generalization of instruction following behavior in profoundly retarded individuals.

    1979-08-01

    Four profoundly retarded male residents of a state institution learned to comply with the instructions "come here," "stay," and "sit." Acquisition occurred in a special therapy room and instructions were presented in a fixed sequence. All subjects learned to comply with the instructions in the training environment. Testing occurred in the subject's ward dayroom where instructions were presented in a random sequence. Despite dramatic changes in the stimulus conditions associated with the transfer to the testing situation the subjects performed close to their asymptotic level. Three experimentally naive subjects participated in a second experiment which was similar to the first, except that the number of acquisition sessions and the number of trials per session were reduced. The reduction in number of acquisition trials did not appear to affect performance in the testing environment. The possibility of terminating off-task behavior of institutionalized individuals by eliciting previously acquired instruction following behavior was discussed.

    Two experiments were conducted to test the effect of a room with sensory equipment, or Snoezelen room, on the stereotypic behavior and engagement of adults with profound mental retardation. In Experiment 1, participants were observed in their living room before and after attending the Snoezelen room. Results showed that there tended to be a reduction in stereotypy and increase in engagement when participants went from their living room to the Snoezelen room, and a return of these behaviors to pre-Snoezelen levels in the living room. Positive effects in the Snoezelen room did not carryover to the living room. In Experiment 2, the living and Snoezelen rooms were compared to an outdoor activity condition with the same participants and target behaviors. Results showed that the outdoor condition was superior, the Snoezelen condition intermediate, and the living room least effective in their impact on stereotypic behavior and engagement. Conceptualizations regarding factors that maintain stereotypic behavior and engagement were discussed in the context of the three experimental conditions.

  4. Behavioral cardiology: recognizing and addressing the profound impact of psychosocial stress on cardiovascular health.

    2008-10-01

    Psychosocial stress exerts independent adverse effects on cardiovascular health. The INTERHEART study reported that psychosocial stress accounted for approximately 30% of the attributable risk of acute myocardial infarction. Prospective studies consistently indicate that hostility, depression, and anxiety are related to increased risk of coronary heart disease and cardiovascular death. A sense of hopelessness, in particular, appears to be strongly correlated with adverse cardiovascular outcomes. Time urgency and impatience have not been consistently related to risk of coronary disease, but increase the likelihood of developing hypertension. Psychosocial stress appears to adversely affect autonomic and hormonal homeostasis, resulting in metabolic abnormalities, inflammation, insulin resistance, and endothelial dysfunction. Also, stress is often associated with self-destructive behavior and medication noncompliance. Psychosocial stress is a highly modifiable risk; many factors have been shown to be protective. These include psychosocial support, regular exercise, stress reduction training, sense of humor, optimism, altruism, faith, and pet ownership. Simple screening questions are available to reliably indicate a patient at risk for psychosocial stress-related health problems.

  7. PROFOUND AND SEXUALLY DIMORPHIC EFFECTS OF CLINICALLY-RELEVANT LOW DOSE SCATTER IRRADIATION ON THE BRAIN AND BEHAVIOR

    Directory of Open Access Journals (Sweden)

    Anna eKovalchuk

    2016-06-01

    Full Text Available Irradiated cells can signal damage and distress to both close and distant neighbors that have not been directly exposed to the radiation (naïve bystanders. While studies have shown that such bystander effects occur in the shielded brain of animals upon body irradiation, their mechanism remains unexplored. Observed effects may be caused by some blood-borne factors; however they may also be explained, at least in part, by very small direct doses received by the brain that result from scatter or leakage. In order to establish the roles of low doses of scatter irradiation in the brain response, we developed a new model for scatter irradiation analysis whereby one rat was irradiated directly at the liver and the second rat was placed adjacent to the first and received a scatter dose to its body and brain. This work focuses specifically on the response of the latter rat brain to the low scatter irradiation dose. Here, we provide the first experimental evidence that very low, clinically relevant doses of scatter irradiation alter gene expression, induce changes in dendritic morphology, and lead to behavioral deficits in exposed animals. The results showed that exposure to radiation doses as low as 0.115 cGy caused changes in gene expression and reduced spine density, dendritic complexity, and dendritic length in the prefrontal cortex tissues of females, but not males. In the hippocampus, radiation altered neuroanatomical organization in males, but not in females. Moreover, low dose radiation caused behavioral deficits in the exposed animals. This is the first study to show that low dose scatter irradiation influences the brain and behavior in a sex-specific way.

    The educational, occupational, and creative accomplishments of the profoundly gifted participants (IQs ⩾ 160) in the Study of Mathematically Precocious Youth (SMPY) are astounding, but are they representative of equally able 12-year-olds? Duke University's Talent Identification Program (TIP) identified 259 young adolescents who were equally gifted. By age 40, their life accomplishments also were extraordinary: Thirty-seven percent had earned doctorates, 7.5% had achieved academic tenure (4.3% at research-intensive universities), and 9% held patents; many were high-level leaders in major organizations. As was the case for the SMPY sample before them, differential ability strengths predicted their contrasting and eventual developmental trajectories-even though essentially all participants possessed both mathematical and verbal reasoning abilities far superior to those of typical Ph.D. recipients. Individuals, even profoundly gifted ones, primarily do what they are best at. Differences in ability patterns, like differences in interests, guide development along different paths, but ability level, coupled with commitment, determines whether and the extent to which noteworthy accomplishments are reached if opportunity presents itself. © The Author(s) 2016.

    Full Text Available Asystole in a non laparoscopic upper abdominal surgery following intense vagal stimulation is a rare event. This case report highlights the need for awareness of such a complication when a thoracic epidural anaesthetic has been given in addition to a general anaesthetic for an upper abdominal procedure. A combined thoracic epidural and general anaesthetic was given. The anterior abdominal wall was retracted forty minutes after administration of the epidural bolus. This maneuver resulted in a profound vagal response with bradycardia and asystole. The patient was resuscitated successfully with a cardiac massage, atropine and adrenaline and the surgery was resumed. Surgery lasted eleven hours and was uneventful.

  17. Staffs' documentation of participation for adults with profound intellectual disability or profound intellectual and multiple disabilities.

    2017-06-21

    This study investigated what areas of International Classification of Functioning, Disability and Health were documented in implementation plans for adults with profound intellectual disability or profound intellectual and multiple disabilities with focus on participation. A document analysis of 17 implementation plans was performed and International Classification of Functioning, Disability and Health was used as an analytic tool. One hundred and sixty-three different codes were identified, especially in the components Activities and participation and Environmental factors. Participation was most frequently coded in the chapters Community, social and civic life and Self-care. Overall, the results showed that focus in the implementation plans concerned Self-care and Community, social and civic life. The other life areas in Activities and participation were seldom, or not at all, documented. A deeper focus on participation in the implementation plans and all life areas in the component Activities and participation is needed. It is important that the documentation clearly shows what the adult wants, wishes, and likes in everyday life. It is also important to ensure that the job description for staff contains both life areas and individual preferences so that staff have the possibility to work to fulfill social and individual participation for the target group. Implications for rehabilitation There is a need for functioning working models to increase participation significantly for adults with profound intellectual disability or profound intellectual and multiple disabilities. For these adults, participation is achieved through the assistance of others and support and services carried out must be documented in an implementation plan. The International Classification of Functioning, Disability and Health can be used to support staff and ensure that information about the most important factors in an individual's functioning in their environment is not omitted in

  18. Profound Olfactory Dysfunction in Myasthenia Gravis

    In this study we demonstrate that myasthenia gravis, an autoimmune disease strongly identified with deficient acetylcholine receptor transmission at the post-synaptic neuromuscular junction, is accompanied by a profound loss of olfactory function. Twenty-seven MG patients, 27 matched healthy controls, and 11 patients with polymiositis, a disease with peripheral neuromuscular symptoms analogous to myasthenia gravis with no known central nervous system involvement, were tested. All were administered the University of Pennsylvania Smell Identification Test (UPSIT) and the Picture Identification Test (PIT), a test analogous in content and form to the UPSIT designed to control for non-olfactory cognitive confounds. The UPSIT scores of the myasthenia gravis patients were markedly lower than those of the age- and sex-matched normal controls [respective means (SDs) = 20.15 (6.40) & 35.67 (4.95); p<0.0001], as well as those of the polymiositis patients who scored slightly below the normal range [33.30 (1.42); p<0.0001]. The latter finding, along with direct monitoring of the inhalation of the patients during testing, implies that the MG-related olfactory deficit is unlikely due to difficulties sniffing, per se. All PIT scores were within or near the normal range, although subtle deficits were apparent in both the MG and PM patients, conceivably reflecting influences of mild cognitive impairment. No relationships between performance on the UPSIT and thymectomy, time since diagnosis, type of treatment regimen, or the presence or absence of serum anti-nicotinic or muscarinic antibodies were apparent. Our findings suggest that MG influences olfactory function to the same degree as observed in a number of neurodegenerative diseases in which central nervous system cholinergic dysfunction has been documented.

  19. Profound Impacts of AN Arctic Face Lift

    Science.gov (United States)

    Nghiem, Son

    Son Nghiem, son.v.nghiem@jpl.nasa.gov Jet Propulsion Laboratory, California Institute of Technology, Pasadena, California, United States The ice cover on the Arctic Ocean has undergone a face lift that removes much of the older and thicker perennial ice and replaces it with the younger and thinner seasonal ice. Although the sea ice cover is a thin skin compared to the depth of the Arctic Ocean, this face lift exerts profound change in the Arctic environment. Here, we present scatterometer remote sensing of Arctic sea ice change and its implication on chemical processes from the ice surface to the troposphere extending into the internal continental land. In the context of a half century change, the extent of perennial ice declines at rate of 0.5 million km2 per decade in the 1970s-1990s while there is no discernable trend in the 1950s-1960s. Abruptly, the rate of decrease has tripled to 1.5 million km2 per decade in the 2000s. A record was set in the reduction of Arctic perennial ice extent in winter 2008. By 1 March 2008, perennial ice extent was reduced by one million km2 compared to that at the same time in 2007. On 1 May 2009, perennial ice extent was reduced to 2.1 million km2 , which is a virtual tie to 2.2 million km2 of perennial ice extent on 1 May 2008 given the uncertainty of ±0.2 million km2 . Although the extent of perennial ice extent is similar, its distribution is quite different, with a significant perennial ice pack in the Beaufort Sea in 2008, and in contrast a large expanse of perennial ice along the Transpolar Drift Stream in 2009. The continuing drastic reduction of perennial ice significantly decreases the overall surface albedo, resulting in enhanced solar heat absorption in spring and summer, which further decreases the Arctic ice pack through the ice-albedo feedback mechanism and ice melt from the underside due to oceanic thermodynamic interactions. Satellite maps of sea ice class distribution show the closely conformation with patterns of

  1. Human dignity and the profoundly disabled: a theological perspective.

    Science.gov (United States)

    Matthews, Pia

    2011-01-01

    One challenge to the concept of human dignity is that it is a rootless notion invoked simply to mask inequalities that inevitably exist between human beings. This privileging of humans is speciesist and its weak point is the profoundly disabled human being. This article argues that far from being a weak point, the profoundly disabled person is a source of strength and witness to the intrinsic dignity that all human beings have by virtue of being human. The disabled represent the reality of human existence that is both strong and fragile. Although human dignity can be understood philosophically its depth is rooted in Christian theological insights. The profoundly disabled occupy a privileged position and share in a theology of mission since they testify to the interdependence of every human being and human dependence on God to a myopic world that only values strength, autonomy and independence.

    Individuals with profound amnesia are markedly impaired in explicitly recalling new episodic events, but appear to preserve the capacity to use information from other sources. Amongst these preserved capacities is the ability to form new memories of an emotional nature - a skill at the heart of developing and sustaining interpersonal relationships. The psychoanalytic study of individuals with profound amnesia might contribute to the understanding the importance of each memory system, including effects on key analytic processes such as transference and countertransference. However, psychoanalytic work in the presence of profound amnesia might also require important technical modifications. In the first report of its kind, we describe observations from a long term psychoanalytic process (72 sessions) with an individual (JL) who has profound amnesia after an anoxic episode. The nature of therapy was shaped by JL's impairment in connecting elements that belong to distant (and even relatively close) moments in the therapeutic process. However, we were also able to document areas of preservation, in what appears to be a functioning therapeutic alliance. As regards transference, the relationship between JL and his analyst can be viewed as the evolution of a narcissistic transference, and case material is provided that maps this into three phases: (i) rejecting; (ii) starting to take in; and (iii) full use of the analytic space - where each phase exhibits differing degrees of permeability between JL and the analyst. This investigation appears to have important theoretical implications for psychoanalytic practice, and for psychotherapy in general - and not only with regard to brain injured populations. We especially note that it raises questions concerning the mechanism of therapeutic action in psychoanalysis and psychotherapy, and the apparent unimportance of episodic memory for many elements of therapeutic change.

  12. Foveal Processing Under Concurrent Peripheral Load in Profoundly Deaf Adults

    Science.gov (United States)

    2016-01-01

    Development of the visual system typically proceeds in concert with the development of audition. One result is that the visual system of profoundly deaf individuals differs from that of those with typical auditory systems. While past research has suggested deaf people have enhanced attention in the visual periphery, it is still unclear whether or not this enhancement entails deficits in central vision. Profoundly deaf and typically hearing adults were administered a variant of the useful field of view task that independently assessed performance on concurrent central and peripheral tasks. Identification of a foveated target was impaired by a concurrent selective peripheral attention task, more so in profoundly deaf adults than in the typically hearing. Previous findings of enhanced performance on the peripheral task were not replicated. These data are discussed in terms of flexible allocation of spatial attention targeted towards perceived task demands, and support a modified “division of labor” hypothesis whereby attentional resources co-opted to process peripheral space result in reduced resources in the central visual field.

    Profound agitation in the prehospital setting confers substantial risk to patients and providers. Optimal chemical sedation in this setting remains unclear. The goal of this study was to describe intubation rates among profoundly agitated patients treated with prehospital ketamine and to characterize clinically significant outcomes of a prehospital ketamine protocol. This was a retrospective cohort study of all patients who received prehospital ketamine, per a predefined protocol, for control of profound agitation and who subsequently were transported to an urban Level 1 trauma center from May 1, 2010 through August 31, 2013. Identified records were reviewed for basic ambulance run information, subject characteristics, ketamine dosing, and rate of intubation. Emergency Medical Services (EMS) ambulance run data were matched to hospital-based electronic medical records. Clinically significant outcomes are characterized, including unadjusted and adjusted rates of intubation. Overall, ketamine was administered 227 times in the prehospital setting with 135 cases meeting study criteria of use of ketamine for treatment of agitation. Endotracheal intubation was undertaken for 63% (85/135) of patients, including attempted prehospital intubation in four cases. Male gender and late night arrival were associated with intubation in univariate analyses (χ2=12.02; P=.001 and χ2=5.34; P=.021, respectively). Neither ketamine dose, co-administration of additional sedating medications, nor evidence of ethanol (ETOH) or sympathomimetic ingestion was associated with intubation. The association between intubation and both male gender and late night emergency department (ED) arrival persisted in multivariate analysis. Neither higher dose (>5mg/kg) ketamine nor co-administration of midazolam or haloperidol was associated with intubation in logistic regression modeling of the 120 subjects with weights recorded. Two deaths were observed. Post-hoc analysis of intubation rates suggested a

    Eighty-seven studies published since 1964 through 1982 on training self-help skills to severely and profoundly mentally retarded persons were analyzed according to 19 parameters reflecting their methodological details. The results showed a steady interest in this research area over time, but 63% of the studies focused on toileting and feeding with fewer studies looking at other self-help skills. Package treatments composed primarily of accelerative techniques were most frequently used to train these skills. Methodologically, it was found that these studies typically involved profoundly mentally retarded people (33% of studies) who were trained by residential staff (69% of studies) in institutional settings (63% of studies). The results also indicated an increase over time in the number of studies rated acceptable on the reliability and design parameters. Finally, very few studies reported assessments of generalization, maintenance, or social validity. It was concluded that, (a) researchers need to broaden their interests in terms of settings, trainers, and behaviors studied to best meet the needs of this population, (b) the experimental quality of this literature is improving, and (c) the social impact of observed behavior changes has yet to be fully explored.

    This study is designed to measure the degree to which spiral ganglion cell (SGC) survival in the left and right ears is similar in profoundly hearing-impaired human patients with symmetric (right/left) etiology and sensitivity. This is of interest because a small difference between ears would imply that one ear could be used as a control ear in temporal bone studies evaluating the impact on SGC survival of a medical intervention in the other ear. Forty-two temporal bones from 21 individuals with bilaterally symmetric profound hearing impairment were studied. Both ears in each individual were impaired by the same etiology. Rosenthal's canal was reconstructed in two dimensions and segmental and total SGCs were counted. Correlation analysis and t-tests were used to compare segmental and total counts of left and right ears. Statistical power calculations illustrate how the results can be used to estimate the effect size (right/left difference in SGC count) that can be reliably identified as a function of sample size. Left counts (segmental and total) were significantly correlated with those in the right ears (p total count were respectively 0.64, 0.91, 0.93, 0.91 and 0.98. The hypothesis that mean segmental and total counts of right and left are the same could not be rejected by paired t-test. The variance in the between-ear difference across the temporal bones studied indicates that useful effect sizes can be reliably identified using subject numbers that are practical for temporal bone studies. For instance, there is 95% likelihood that an interaural difference in SGC count of approximately 1000 cells associated with a treatment/manipulation of one ear will be reliably detected in a bilaterally-symmetric profound hearing loss population of temporal bones from approximately 10 subjects.

    The interactions among cells or among cells and components of the extracellular matrix, is a crucial pathophysiological process involving some molecules collectively known as adhesion molecules (CAMs). Glycoprotein IIb / IIIa receptors are only restricted to blood platelets and they bind fibrinogen and adhesion proteins such as fibronectin, vitronectin, von Willebrand factor to form cross bridges between adjacent platelets. IIb/IIIa receptor antagonists are an object of intense research activity for target therapy worldwide during the last decades. Three GPIIb/IIIa inhibitors, abciximab, tirofiban, and eptifibatide, have been approved for clinical use. Profound thrombocytopenia is an uncommon but clinically important complication of glycoprotein IIb/IIIa inhibitors. This case report discusses a forty-four-year-old male patient with acute coronary syndrome who underwent percutaneous coronary intervention and developed profound thrombocytopenia within 4 hours of first administration of eptifibatide. This report adds another case of eptifibatide-induced thrombocytopenia to the medical literature and endorses the importance of platelet count monitoring after initiating therapy with this agent.

  18. Persistent Thalamic Sound Processing Despite Profound Cochlear Denervation

    Full Text Available Neurons at higher stages of sensory processing can partially compensate for a sudden drop in input from the periphery through a homeostatic plasticity process that increases the gain on weak afferent inputs. Even after a profound unilateral auditory neuropathy where > 95% of synapses between auditory nerve fibers and inner hair cells have been eliminated with ouabain, central gain can restore the cortical processing and perceptual detection of basic sounds delivered to the denervated ear. In this model of profound auditory neuropathy, cortical processing and perception recover despite the absence of an auditory brainstem response (ABR or brainstem acoustic reflexes, and only a partial recovery of sound processing at the level of the inferior colliculus (IC, an auditory midbrain nucleus. In this study, we induced a profound cochlear neuropathy with ouabain and asked whether central gain enabled a compensatory plasticity in the auditory thalamus comparable to the full recovery of function previously observed in the auditory cortex (ACtx, the partial recovery observed in the IC, or something different entirely. Unilateral ouabain treatment in adult mice effectively eliminated the ABR, yet robust sound-evoked activity persisted in a minority of units recorded from the contralateral medial geniculate body (MGB of awake mice. Sound-driven MGB units could decode moderate and high-intensity sounds with accuracies comparable to sham-treated control mice, but low-intensity classification was near chance. Pure tone receptive fields and synchronization to broadband pulse trains also persisted, albeit with significantly reduced quality and precision, respectively. MGB decoding of temporally modulated pulse trains and speech tokens were both greatly impaired in ouabain-treated mice. Taken together, the absence of an ABR belied a persistent auditory processing at the level of the MGB that was likely enabled through increased central gain. Compensatory

    A longitudinal study indicated that a single group of adults living in a large state institution (O'Berry Center in Goldsboro, North Carolina) benefited from receiving active treatment, although no control group was permitted. After five years, 59 individuals with profound mental retardation improved their skills in six general areas of dressing, grooming, eating, toileting, communication, and social interaction. After five more years of active treatment, 51 persons who had remained in the program maintained their skills in dressing, grooming, eating, and communication. Significant improvement in the use of toilet and a loss in social interaction were observed. Although the participants were 10 years older at the end of this study, their adaptive behaviors, in comparison to the date of entry, either improved or were maintained. Therefore, aging was not associated with decline in skills.

    1981-03-01

    The prelinguistic, nonverbal communicative behavior of 40 institutionalized severely and profoundly retarded children and adolescents functioning at various stages of Piaget's sensorimotor period was examined. Five scales of the Uzgiris and Hunt (1975) sensorimotor assessment were used to determine general level of sensorimotor functioning. A standard set of communication elicitation tasks was employed to examine the gestures used to communicate in both imperative and declarative contexts. More competent sensorimotor performance was associated with higher frequency of more sophisticated and symbolic forms of gestural communication, and subjects generally used more complex gestures to communicate in the imperative than in the declarative tasks. Applicability of the results to the design of future language-intervention programs and their implications for general theory concerning the relations between language and cognition and between normal and atypical development were discussed.

    During atrial fibrillation (AF), multiple wandering propagation wavelets at high rates drift around both atria under controversial hierarchical models. Antiarrhythmic drugs modify the cardiac ionic currents supporting the fibrillation process within the atria, and can alter AF propagation dynamics and even terminate the arrhythmia. However, some other drugs, theoretically nonantiarrhythmic, may slightly block particular cardiac ionic currents through uncertain mechanisms in such a subtle way at regular heart rates that may have been pharmacologically overlooked. These potential effects might be better exposed at much higher activation rates as in AF, where atrial cells depolarize over 400 times per second. In this review, we aimed to compile and discuss results from several studies evaluating the net effect of profound sedation with propofol on atrial cells and atrioventricular (AV) conduction. Propofol is a very commonly used anesthetic agent, and its possible effect on AF dynamics has systematically not been taken into account in the myriad of clinical studies dealing with AF intracardiac recordings. The possible effect of sedation with propofol on AF was evaluated through the analysis of AF propagation patterns before and after its infusion in a series of patients submitted to pulmonary vein ablation. Effect on AV conduction will be discussed as well. ©2013, The Authors. Journal compilation ©2013 Wiley Periodicals, Inc.

    The contribution of a two-channel vibrotactile aid (Trill VTA 2/3, AVR Communications LTD) to the audiovisual perception of speech was evaluated in four young children with profound hearing loss using words and speech pattern contrasts. An intensive, hierarchical, and systematic training program was provided. The results show that the addition of the tactile (T) modality to the auditory and visual (A+V) modalities enhanced speech perception performance significantly on all tests. Specifically, at the end of the training sessions, the tactile supplementation increased word recognition scores in a 44-word, closed-set task by 12 percentage points; detection of consonant in final position by 50 percentage points; detection of sibilant in final position by 30 percentage points; and detection of voicing in final position by 25 percentage points. Significant learning over time was evident for all test materials, in all modalities. As expected, fastest learning (i.e., smallest time constants) was found for the AVT condition. The results of this study provide further evidence that sensory information provided by the tactile modality can enhance speech perception in young children.

    BACKGROUND Deaf persons, a documented minority population, have low reading levels and difficulty communicating with physicians. The effect of these on their knowledge of cancer prevention recommendations is unknown. METHODS A cross-sectional study of 222 d/Deaf persons in Michigan, age 18 and older, chose one of four ways (voice, video of a certified American Sign Language interpreter, captions, or printed English) to complete a self-administered computer video questionnaire about demographics, hearing loss, language history, health-care utilization, and health-care information sources, as well as family and social variables. Twelve questions tested their knowledge of cancer prevention recommendations. The outcome measures were the percentage of correct answers to the questions and the association of multiple variables with these responses. RESULTS Participants averaged 22.9% correct answers with no gender difference. Univariate analysis revealed that smoking history, types of medical problems, last physician visit, and women having previous cancer preventive tests did not affect scores. Improved scores occurred with computer use (p = 0.05), higher education (p English in multiple situations (p English use (p = 0.01) and believing that smoking was bad (p = 0.05) were associated with improved scores. CONCLUSION Persons with profound hearing loss have poor knowledge of recommended cancer prevention interventions. English use in multiple settings was strongly associated with increased knowledge.

    Cochlear implants have become the method of choice for the treatment of severe-to-profound hearing loss in both children and adults. Its benefits are well documented in the pediatric and adult population. Also deaf children with additional needs, including autism, have been covered by this treatment. The aim of this study was to assess the benefits from cochlear implantation in deafened children with autism as the only additional disability. This study analyzes data of six children. The follow-up time was at least 43 months. The following data were analyzed: medical history, reaction to music and sound, Ling's six sounds test, onomatopoeic word test, reaction to spoken child's name, response to requests, questionnaire given to parents, sound processor fitting sessions and data. After cochlear implantation each child presented other communication skills. In some children, the symptoms of speech understanding were observed. No increased hyperactivity associated with daily use cochlear implant was observed. The study showed that in autistic children the perception is very important for a child's sense of security and makes contact with parents easier. Our study showed that oral communication is not likely to be a realistic goal in children with cochlear implants and autism. The implantation results showed benefits that varied among those children. The traditional methods of evaluating the results of cochlear implantation in children with autism are usually insufficient to fully assess the functional benefits. These benefits should be assessed in a more comprehensive manner taking into account the limitations of communication resulting from the essence of autism. It is important that we share knowledge about these complex children with cochlear implants. Copyright © 2016 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

    Background and Aims Bariatric surgery is increasingly performed worldwide to treat morbid obesity and is also known as metabolic surgery to reflect its beneficial metabolic effects especially with respect to improvement in type 2 diabetes. Understanding surgical weight loss mechanisms and metabolic modulation is required to enhance patient benefits and operative outcomes. Methods We apply a parallel and statistically integrated metagenomic and metabonomic approach to characterize Roux-en-Y gastric bypass (RYGB) effects in a rat model. Results We show substantial shifts of the main gut phyla towards higher levels of Proteobacteria (52-fold) specifically Enterobacter hormaechei. We also find low levels of Firmicutes (4.5-fold) and Bacteroidetes (2-fold) in comparison to sham-operated rats. Faecal extraction studies reveal a decrease in faecal bile acids and a shift from protein degradation to putrefaction through decreased faecal tyrosine with concomitant increases in faecal putrescine and diamnoethane. We find decreased urinary amines and cresols and demonstrate indices of modulated energy metabolism post-RYGB including decreased urinary succinate, 2-oxoglutarate, citrate and fumarate. These changes could also indicate renal tubular acidosis, which associates with increased flux of mitochondrial tricarboxylic acid cycle intermediates. A surgically-induced effect on the gut-brain-liver metabolic axis is inferred by increased neurotropic compounds; faecal γ-aminobutyric acid (GABA) and glutamate. Conclusion This profound co-dependence of mammalian and microbial metabolism, which is systematically altered following RYGB surgery, suggests that RYGB exerts local and global metabolic activities. The effect of RYGB surgery on the host metabolic-microbial crosstalk augments our understanding of the metabolic phenotype of bariatric procedures and can facilitate enhanced treatments for obesity-related diseases.

    Speech perception tests are an important part of procedures for diagnosing pre-verbal hearing loss. Merely establishing a child's hearing threshold with and without a hearing aid is not sufficient to ensure an adequate evaluation with a view to selecting cases suitable for cochlear implants because it fails to indicate the real benefit obtained from using a conventional hearing aid reliably. Speech perception tests have proved useful not only for patient selection, but also for subsequent evaluation of the efficacy of new hearing aids, such as tactile devices and cochlear implants. In clinical practice, the tests most commonly adopted with small children are: The Auditory Comprehension Test (ACT), Discrimination after Training (DAT), Monosyllable, Trochee, Spondee tests (MTS), Glendonald Auditory Screening Priocedure (GASP), Early Speech Perception Test (ESP), Rather than considering specific results achieved in individual cases, reference is generally made to the four speech perception classes proposed by Moog and Geers of the CID of St. Louis. The purpose of this classification, made on the results obtained with suitably differentiated tests according to the child's age and language ability, is to detect differences in perception of a spoken message in ideal listening conditions. To date, no italian language speech perception test has been designed to establish the assessment of speech perception level in children with profound hearing impairment. We attempted, therefore, to adapt the existing English tests to the Italian language taking into consideration the differences between the two languages. Our attention focused on the ESP test since it can be applied to even very small children (2 years old). The ESP is proposed in a standard version for hearing-impaired children over the age of 6 years and in a simplified version for younger children. The rationale we used for selecting Italian words reflect the rationale established for the original version, but the

    Full Text Available Objective. To evaluate Auditory Steady-State Responses (ASSR at high intensities in pediatric cochlear implant candidates and to compare the results to behavioral tests responses. Methods. This prospective study evaluated 42 children with suspected severe-to-profound hearing loss, aged from 3 to 72 months. All had absent ABR and OAE responses. ASSR were evoked using binaural single frequency stimuli at 110 dB HL with a 10 dB down-seeking procedure. ASSR and behavioral test results were compared. Results. Forty-two subjects completed both ASSR and behavioral evaluation. Eleven children (26.2% had bilateral responses. Four (9.5% showed unilateral responses in at least two frequencies, all confirmed by behavioral results. Overall 61 ASSR responses were obtained, most (37.7% in 500 Hz. Mean thresholds were between 101.3 and 104.2 dB HL. Among 27 subjects with absent ASSR, fifteen had no behavioral responses. Seven subjects showed behavioral responses with absent ASSR responses. No spurious ASSR responses were observed at 100 or 110 dB HL. Conclusion. ASSR is a valuable tool to detect residual hearing. No false-positive ASSR results were observed among 42 children, but in seven cases with absent ASSR, the test underestimated residual hearing as compared to the behavioral responses.

    The present research investigates the associations between holding favorable views of potential Democratic or Republican candidates for the US presidency 2016 and seeing profoundness in bullshit statements. In this contribution, bullshit is used as a technical term which is defined as communicative expression that lacks content, logic, or truth from the perspective of natural science. We used the Bullshit Receptivity scale (BSR) to measure seeing profoundness in bullshit statements. The BSR scale contains statements that have a correct syntactic structure and seem to be sound and meaningful on first reading but are actually vacuous. Participants (N = 196; obtained via Amazon Mechanical Turk) rated the profoundness of bullshit statements (using the BSR) and provided favorability ratings of three Democratic (Hillary Clinton, Martin O'Malley, and Bernie Sanders) and three Republican candidates for US president (Ted Cruz, Marco Rubio, and Donald Trump). Participants also completed a measure of political liberalism/conservatism. Results revealed that favorable views of all three Republican candidates were positively related to judging bullshit statements as profound. The smallest correlation was found for Donald Trump. Although we observe a positive association between bullshit and support for the three Democrat candidates, this relationship is both substantively small and statistically insignificant. The general measure of political liberalism/conservatism was also related to judging bullshit statements as profound in that individuals who were more politically conservative had a higher tendency to see profoundness in bullshit statements. Of note, these results were not due to a general tendency among conservatives to see profoundness in everything: Favorable views of Republican candidates and conservatism were not significantly related to profoundness ratings of mundane statements. In contrast, this was the case for Hillary Clinton and Martin O'Malley. Overall, small

The BSR scale contains statements that have a correct syntactic structure and seem to be sound and meaningful on first reading but are actually vacuous. Participants (N = 196; obtained via Amazon Mechanical Turk rated the profoundness of bullshit statements (using the BSR and provided favorability ratings of three Democratic (Hillary Clinton, Martin O'Malley, and Bernie Sanders and three Republican candidates for US president (Ted Cruz, Marco Rubio, and Donald Trump. Participants also completed a measure of political liberalism/conservatism. Results revealed that favorable views of all three Republican candidates were positively related to judging bullshit statements as profound. The smallest correlation was found for Donald Trump. Although we observe a positive association between bullshit and support for the three Democrat candidates, this relationship is both substantively small and statistically insignificant. The general measure of political liberalism/conservatism was also related to judging bullshit statements as profound in that individuals who were more politically conservative had a higher tendency to see profoundness in bullshit statements. Of note, these results were not due to a general tendency among conservatives to see profoundness in everything: Favorable views of Republican candidates and conservatism were not significantly related to profoundness ratings of mundane statements. In contrast, this was the case for Hillary Clinton and Martin O

    The Allan-Herndon-Dudley syndrome is caused by mutations in the thyroid hormone transporter, Monocarboxylate transporter 8 (MCT8). It is characterized by profound intellectual disability and abnormal thyroid function. We report on a patient with Allan-Herndon-Dudley syndrome (AHDS) with profound sensorineural hearing loss which is not usually a feature of AHDS and which may have been due to a coexisting nonsense mutation in Microphthalmia-associated transcription factor (MITF). © 2015 Wiley Periodicals, Inc.

    The aim of the study was to characterize the audiological consequences of congenital cytomegalovirus infection (CMV) and to evaluate the outcome of rehabilitation with hearing aids and/or cochlear implant (CI), associated with an adequate speech-language therapy. A retrospective review of data was made from a total of 16 infants, affected by severe to profound hearing loss from congenital CMV infection, referred to a tertiary audiological center for rehabilitation. Audiological evaluation was performed using behavioral audiometry, auditory brainstem responses (ABR) and/or electrocochleography (ECochG). Of the 16 children (median age at diagnosis of hearing loss: 21.33 +/- 0.7 months) with CMV hearing loss, 14 were affected by profound bilateral hearing loss and received a CI, while 2 were affected by bilateral severe hearing loss and received hearing aids. Cochlear implants can provide useful speech comprehension to patients with CMV-related deafness, even if language development is lower when compared to a group of Connexin (Cx) 26+ cochlear-implanted children (eight subjects), matched for age. Congenital CMV infection still represents a serious clinical condition, as well as an important cause of hearing loss in children. More studies have claimed to identify the pathophysiological mechanisms of damage and thus to ensure a better therapeutic approach. Nonetheless, in cases of CMV-deafened babies, the overall outcome of cochlear implantation is good.

    Full Text Available To identify risk factors and develop a prediction model for the development of profound and recurrent shock amongst children presenting with dengue shock syndrome (DSS.We analyzed data from a prospective cohort of children with DSS recruited at the Paediatric Intensive Care Unit of the Hospital for Tropical Disease in Ho Chi Minh City, Vietnam. The primary endpoint was "profound DSS", defined as ≥2 recurrent shock episodes (for subjects presenting in compensated shock, or ≥1 recurrent shock episodes (for subjects presenting initially with decompensated/hypotensive shock, and/or requirement for inotropic support. Recurrent shock was evaluated as a secondary endpoint. Risk factors were pre-defined clinical and laboratory variables collected at the time of presentation with shock. Prognostic model development was based on logistic regression and compared to several alternative approaches.The analysis population included 1207 children of whom 222 (18% progressed to "profound DSS" and 433 (36% had recurrent shock. Independent risk factors for both endpoints included younger age, earlier presentation, higher pulse rate, higher temperature, higher haematocrit and, for females, worse hemodynamic status at presentation. The final prognostic model for "profound DSS" showed acceptable discrimination (AUC=0.69 for internal validation and calibration and is presented as a simple score-chart.Several risk factors for development of profound or recurrent shock among children presenting with DSS were identified. The score-chart derived from the prognostic models should improve triage and management of children presenting with DSS in dengue-endemic areas.

    Full Text Available The article analyzes the software and hardware, that give people with profound visual impairments the opportunity to work on the computer. Attention is drawn to the Braille printers, relief-dot displays, voice synthesizers, scanners that can read, adaptation and correction programs and so on. It is emphasized that ICT for the blind is a factor of their inclusion in the life as the subjects of action. For solving this problem people with profound visual impairments need systemic help of the state and civil society in getting programs and equipment, because they are high-tech, and therefore expensive. It is important to spread the information about the activity of the centers of tiflo-computerization, to organize the laboratories of correction and socialization of people with profound visual impairments, to provide the training of the specialists.

We used a force platform, AccuSway Plus, where the tests were conducted under the experimental conditions: open base, eyes open (OBEO; open base, eyes closed (OBEC; closed base, eyes open (CBEO; closed base, eyes closed (CBEC. The body sway velocity (V of the center of pressure, the displacement in the anteroposterior direction (COPap and mediolateral (COPml of the center of pressure were the parameters to evaluate the postural control. For statistical analysis we used the nonparametric Mann–Whitney U test, with a significance level of 5%.Results: In comparisons of variables between the groups, the experimental group outperformed by at least 75% of the control group values. In terms of global trends, the experimental group shows higher values of body oscillations in all experimental conditions and variables evaluated. Children with hearing loss had poorer balance performance compared to the group of hearing. The inferential analysis revealed a statistically significant difference in the balance between deaf and hearing children in the OBEC experimental condition in relation to the COPml parameter (P = 0.04. There were no statistically significant differences in comparisons between the sexes when the groups were analyzed separately. The prevalence of unknown etiology

    Full Text Available Communication, cognition, language, and speech are interrelated and develop together. It should come as no surprise to us that the key to intervention with deaf children is to establish, as early as possible, a functional communication system for the child and the parents. Early intervention programs need to be multidisciplinary, technologically sound and most important, it should take cognizance of the specific context (community, country in which the child and family function. The main aim of this study was to obtain oral communication development regarding current status of the intervention (aural habilitation and speech therapyfor children with severe to profound hearing impairment in Iran. A prospective longitudinal study was undertaken on a consecutive group of children with severe to profound deafness.

The average of their speech intelligibility scores was near 70% at age 6, which was accounted as poor oral communication and only two of them were able to communicate by spoken language. An integrated intervention services continued again for one year and their oral communication skill was assessed by their speech intelligibility. The intelligibility test of children was recorded on audio-tape, when they read 10 questions such as where is your home. This can be answered only in one word. Each tape was presented to10 normal hearing listeners, and their task was to write down, the answers in Persian orthography. At the beginning (at age 6 the average speech intelligibility score of these children was 72% and only two of them had score of 90% and 100%. At age 7, all of the severe groups were over 90%, and only two profound ones achieved the score of 48% and 62%. All of severe groups develop oral communication, but profound ones had a semi-intelligible speech

    Fractures are more prevalent among people with severe and profound developmental disabilities than in the general population. In order to characterize the tendency of these people to fracture, and to identify features that may guide the development of preventive strategies, we analyzed fracture epidemiology in people with severe and profound developmental disabilities who lived in a stable environment. Data from a 23-year longitudinal cohort registry of 1434 people with severe and profound developmental disabilities were analyzed to determine the effects of age, gender, mobility, bone fractured, month of fracture, and fracture history upon fracture rates. Eighty-five percent of all fractures involved the extremities. The overall fracture rate increased as mobility increased. In contrast, femoral shaft fracture risk was substantially higher in the least mobile [relative risk (RR), 10.36; 95% confidence interval (CI), 3.29-32.66] compared with the most mobile group. Although the overall fracture rate was not associated with age, the femoral shaft fractures decreased but hand/foot fractures increased with age. Overall fracture risk declined in August and September (RR, 0.70; 95% CI, 0.55-0.89), being especially prominent for tibial/fibular fractures (RR, 0.31; 95% CI, 0.13-0.70). Gender was not a factor in fracture risk. Two primary fracture mechanisms are apparent: one, largely associated with lack of weight-bearing in people with the least mobility, is exemplified by femoral fractures during non-traumatic events as simple as diapering or transfers; the other, probably due to movement- or fall-related trauma, is exemplified by hand/foot fractures in people who ambulate. The fracture experience of people with severe and profound developmental disabilities is unique and, because it differs qualitatively from postmenopausal osteoporosis, may require population-specific methods for assessing risk, for improving bone integrity, and for reduction of falls and accidents

    To define a distinct SCN1A developmental and epileptic encephalopathy with early onset, profound impairment, and movement disorder. A case series of 9 children were identified with a profound developmental and epileptic encephalopathy and SCN1A mutation. We identified 9 children 3 to 12 years of age; 7 were male. Seizure onset was at 6 to 12 weeks with hemiclonic seizures, bilateral tonic-clonic seizures, or spasms. All children had profound developmental impairment and were nonverbal and nonambulatory, and 7 of 9 required a gastrostomy. A hyperkinetic movement disorder occurred in all and was characterized by dystonia and choreoathetosis with prominent oral dyskinesia and onset from 2 to 20 months of age. Eight had a recurrent missense SCN1A mutation, p.Thr226Met. The remaining child had the missense mutation p.Pro1345Ser. The mutation arose de novo in 8 of 9; for the remaining case, the mother was negative and the father was unavailable. Here, we present a phenotype-genotype correlation for SCN1A. We describe a distinct SCN1A phenotype, early infantile SCN1A encephalopathy, which is readily distinguishable from the well-recognized entities of Dravet syndrome and genetic epilepsy with febrile seizures plus. This disorder has an earlier age at onset, profound developmental impairment, and a distinctive hyperkinetic movement disorder, setting it apart from Dravet syndrome. Remarkably, 8 of 9 children had the recurrent missense mutation p.Thr226Met. Copyright © 2017 The Author(s). Published by Wolters Kluwer Health, Inc. on behalf of the American Academy of Neurology.

    2010-09-01

    Full Text Available Abstract Background Acetylcholinesterase inhibitors cannot rapidly reverse profound neuromuscular block. Sugammadex, a selective relaxant binding agent, reverses the effects of rocuronium and vecuronium by encapsulation. This study assessed the efficacy of sugammadex compared with neostigmine in reversal of profound vecuronium-induced neuromuscular block under sevoflurane anesthesia. Methods Patients aged ≥18 years, American Society of Anesthesiologists class 1-4, scheduled to undergo surgery under general anesthesia were enrolled in this phase III, multicenter, randomized, safety-assessor blinded study. Sevoflurane anesthetized patients received vecuronium 0.1 mg/kg for intubation, with maintenance doses of 0.015 mg/kg as required. Patients were randomized to receive sugammadex 4 mg/kg or neostigmine 70 μg/kg with glycopyrrolate 14 μg/kg at 1-2 post-tetanic counts. The primary efficacy variable was time from start of study drug administration to recovery of the train-of-four ratio to 0.9. Safety assessments included physical examination, laboratory data, vital signs, and adverse events. Results Eighty three patients were included in the intent-to-treat population (sugammadex, n = 47; neostigmine, n = 36. Geometric mean time to recovery of the train-of-four ratio to 0.9 was 15-fold faster with sugammadex (4.5 minutes compared with neostigmine (66.2 minutes; p Conclusions Recovery from profound vecuronium-induced block is significantly faster with sugammadex, compared with neostigmine. Neostigmine did not rapidly reverse profound neuromuscular block (Trial registration number: NCT00473694.

    Adults with unilateral hearing loss often demonstrate decreased sound localization ability and report that situations requiring spatial hearing are especially challenging. Few studies have evaluated localization abilities combined with training in this population. The present pilot study examined whether localization of two sound types would improve after training, and explored the relation between localization ability or training benefit and demographic factors. Eleven participants with unilateral severe to profound hearing loss attended five training sessions; localization cues gradually decreased across sessions. Localization ability was assessed pre- and post-training. Assessment stimuli were monosyllabic words and spectral and temporal random spectrogram sounds. Root mean square errors for each participant and stimulus type were used in group and correlation analyses; individual data were examined with ordinary least squares regression. Mean pre-to post-training test results were significantly different for all stimulus types. Among the participants, eight significantly improved following training on at least one localization measure, whereas three did not. Participants with the poorest localization ability improved the most and likewise, those with the best pre-training ability showed the least training benefit. Correlation results suggested that test age, age at onset of severe to profound hearing loss and better ear high frequency audibility may contribute to localization ability. Results support the need for continued investigation of localization training efficacy and consideration of localization training within rehabilitation protocols for individuals with unilateral severe to profound hearing loss.

    Full Text Available Background and Aim: Research conducted since the early 1900s has consistently identified differences between deaf and hearing children on performance of a wide variety of motor tasks, most notably balance. Our study was performed to test static and dynamic balance skills in congenital severe to profound hearing impaired children in comparison with normal age-matched children.Methods: This cross-sectional study was conducted on 30 severe to profound hearing impaired and 40 normal children with age 6 to 10 years old. Bruininks-Oseretsky test of motor proficiency 2, balance subset with 9 parts was used for evaluation of balance skills.Results: Hearing-impaired children showed 16.7 to 100% fail results in 7 parts of the balance subset. In normal children fail result was revealed just in 3 parts of the balance subset from 2.5 to 57.5%, and differences between two groups were significant (p<0.0001. There was a significant difference between two groups in two static balance skills of standing on one leg on a line and standing on one leg on a balance beam with eyes closed (p<0.0001.conclusion: It seems that development of static balance skills are longer than dynamic ones. Because severe to profound hearing-impaired children showed more weakness than normal children in both static and dynamic balance abilities, functional tests of balance proficiency can help to identify balance disorders in these children.

    Objective of this study is to know how a frequency compression hearing aid with new concepts is beneficial for severe-to-profound hearing impairments. (2) Clinical trials of this hearing aid were conducted for 11 severe-to-profound hearing impaired listeners. These 11 wore the frequency compression hearing aid in their daily life and reported subjectively on its performance. Speech recognition tests with five listeners and audio-visual short sentence recognition tests with three listeners were also conducted. This hearing aid can separately adjust the fundamental frequency from the spectral envelope of input speech and can adjust frequency response by use of a post-processing digital filter. (3) Five listeners out of these 11 came to prefer this hearing aid in their daily life and are still wearing it. The results of the speech recognition tests show that the speech recognition scores were not improved for all listeners and the results of the audio-visual short sentence recognition tests do that the audio-visual recognition scores were improved for two listeners. (4) There were some severe-to-profound hearing impaired listeners who preferred the frequency compression hearing aid finally. It is also suggested that the benefits of this hearing aid may be evaluated correctly using not only speech but also visual materials.

  19. Maturation of the mitochondrial redox response to profound asphyxia in fetal sheep.

    Directory of Open Access Journals (Sweden)

    Paul P Drury

    Full Text Available Fetal susceptibility to hypoxic brain injury increases over the last third of gestation. This study examined the hypothesis that this is associated with impaired mitochondrial adaptation, as measured by more rapid oxidation of cytochrome oxidase (CytOx during profound asphyxia.Chronically instrumented fetal sheep at 0.6, 0.7, and 0.85 gestation were subjected to either 30 min (0.6 gestational age (ga, n = 6, 25 min (0.7 ga, n = 27 or 15 min (0.85 ga, n = 17 of complete umbilical cord occlusion. Fetal EEG, cerebral impedance (to measure brain swelling and near-infrared spectroscopy-derived intra-cerebral oxygenation (ΔHb = HbO(2 - Hb, total hemoglobin (THb and CytOx redox state were monitored continuously. Occlusion was associated with profound, rapid fall in ΔHb in all groups to a plateau from 6 min, greatest at 0.85 ga compared to 0.6 and 0.7 ga (p<0.05. THb initially increased at all ages, with the greatest rise at 0.85 ga (p<0.05, followed by a progressive fall from 7 min in all groups. CytOx initially increased in all groups with the greatest rise at 0.85 ga (p<0.05, followed by a further, delayed increase in preterm fetuses, but a striking fall in the 0.85 group after 6 min of occlusion. Cerebral impedance (a measure of cytotoxic edema increased earlier and more rapidly with greater gestation. In conclusion, the more rapid rise in CytOx and cortical impedance during profound asphyxia with greater maturation is consistent with increasing dependence on oxidative metabolism leading to earlier onset of neural energy failure before the onset of systemic hypotension.

    Hypotension caused by hypovolemic, hemorrhagic shock induces disturbances in the immune system that may contribute to an increased susceptibility to sepsis. The effect of chemically induced hypotension on circulating cytokines and adhesion molecules has not been investigated yet. In 21 patients scheduled for resection of malignant choroidal melanoma of the eye the perioperative serum levels of the cytokines IL-1beta, IL-6, IL-10, TNF-alpha, and the adhesion molecules sE-Selectin and sICAM-1 were investigated. Moderate hypothermia of 32 degrees C was induced in all patients. In 14 patients profound hypotension (mean arterial blood pressure 35-40 mmHg, hypotension group) was induced by enalapril and nitroglycerin for a mean duration of 71 min. In 7 patients the tumor was not resectable, and hypotension was not induced (controls). We did not detect significant differences in serum levels of cytokines or sE-Selectin perioperatively in patients with profound hypotension compared with controls. In both groups IL-6 serum levels increased significantly and reached a maximum after rewarming (17 +/- 6 and 16 +/- 5 pg/dL, respectively, P < 0.001). IL-1beta, IL-10, and TNF-alpha did not change perioperatively in both groups. On the first postoperative day sICAM-1 serum levels were significantly increased in both groups (mean increase of 96 and 54 ng/mL, respectively, P < 0.01 and P < 0.05). We conclude from this study that profound normovolemic arterial hypotension does not seem to have effects on serum levels of circulating IL-1beta, IL-6, IL-10, TNF-alpha, and sE-Selectin. Perioperative moderate hypothermia may be the reason for the postoperative increase in sICAM-1 levels independent of the blood pressure.

    The glycoprotein IIb-IIIa inhibitor eptifibatide has been shown to be beneficial in the treatment of acute coronary syndromes and during percutaneous coronary intervention (PCI). Case reports of acute profound thrombocytopenia have been reported with eptifibatide, yet the true incidence of this reaction is unknown. We describe a 50-year-old woman with severe coronary artery disease who developed acute profound thrombocytopenia after readministration of eptifibatide. Eptifibatide was administered through hospital day 3, when it was discontinued in preparation for coronary angiography and PCI; the drug was restarted on day 5. On hospital day 6, she was noted to have a platelet count below 5 x 10(3)/mm,(3) indicating a profound decrease from a baseline of 456 x 10(3)/mm(3) on admission. Eptifibatide, heparin, vancomycin, and clopidogrel were potential causative agents. Anticoagulation and vancomycin were stopped, and her platelet count increased to 30 x 10(3)/mm(3) on day 7. Subsequent reexposure to heparin and vancomycin yielded no adverse effects. The patient's platelet count increased over the remainder of her hospitalization, and she was discharged home on day 19. Based on clinical presentation and negative heparin platelet factor 4 antibody test, eptifibatide was the most likely cause of thrombocytopenia. Use of the Naranjo adverse drug reaction probability scale indicated that eptifibatide was the probable cause of thrombocytopenia (score of 5); scores of 1 (possible) or 0 (doubtful) were derived with heparin, vancomycin, and clopidogrel. We conducted a literature search and compiled information from published case reports to describe the pattern of onset and recovery of eptifibatide-induced thrombocytopenia. In all patients receiving eptifibatide, routine platelet counts should be monitored at baseline and within 2-6 hours after starting the drug.

  2. The Differential Effects of Attentional Focus in Children with Moderate and Profound Visual Impairments

    Full Text Available It has been consistently reported that an external focus of attention leads to better motor performance than an internal focus, but no research to date has explored this effect in a population with visual impairments (VI. External focus statements typically reference something in the environment (e.g., target that may be difficult to conceptualize for people with VI since they cannot generate a visual representation of the object of focus. Internal focus statements could be more closely identifiable with proprioception that is not impaired in this population. Recent studies have reported that sighted adults with temporarily obstructed vision are able to receive an external focus benefit when performing discrete tasks (i.e., golf putt and vertical jump, however, it is unclear if those with VI would experience the same benefit. The purpose of this investigation was to compare how an internal focus and external focus impact the balance of children with VI. Eighteen children with VI were grouped into a moderate (n = 11 and a profound VI group (n = 7. Participants completed a familiarization trial, an internal focus trial (i.e., focusing on feet and an external focus trial (i.e., focusing on markers in a counterbalanced order. The moderate VI group had a lower root mean square error while using an external focus (p = 0.04, while the profound VI group did not differ between conditions (p > 0.05. These results suggest that while performing a task reliant on sensory feedback, an external focus benefit may be dependent on the severity of VI. Further research is needed to examine whether external focus statements can be presented in a way that may be more intuitive to those with profound VI. These findings may help to influence how professionals in health-related fields (e.g., physical therapist and physical educators give instructions on motor performance to populations with VI.

  3. Spider Silk Violin Strings with a Unique Packing Structure Generate a Soft and Profound Timbre

    2012-04-01

    We overcome the difficulties in pulling long draglines from spiders, twist bundles of dragline filaments, and succeed in preparing violin strings. The twisting is found to change the cross section shapes of filaments from circular to polygonal and to optimize the packing structure with no openings among filaments providing mechanically strong and elastic strings. The spider string signal peaks of overtones for the violin are relatively large at high frequencies, generating a soft and profound timbre. Such a preferable timbre is considered to be due to the unique polygonal packing structure which provides valuable knowledge for developing new types of materials.

    Vasovagal syncope (VVS) is an alarming yet benign condition that may present postoperatively for the first time in otherwise healthy patients. Although VVS is associated anecdotally with nasal manipulation, no data have been found to quantify this incidence with otolaryngology surgeries. We present a case of profound, recurrent syncope and documented asystole with an initial diagnosis of glossopharyngeal neuralgia. We conclude with a discussion of neurally mediated syncope particular to the perioperative setting. It is essential to recognize neurocardiogenic etiology to differentiate it from other more concerning causes of syncope and asystole. Published by Elsevier Inc.

    Learning disability combined with hearing impairment (LDHI) is a poor prognostic factor for the language development of hearing impaired children after educational intervention. A typical example of a child with LDHI and effective interventions provided by cochlear implants are presented in this report. A case of congenital cytomegaloviral infection that showed dysgraphia as well as profound deafness was reported and an underlying visual processing problem diagnosed in the present case caused the patient's dysgraphia. The dysgraphia could be circumvented by the use of auditory memory fairly established by a cochlear implant.

    Full Text Available Lemierre’s syndrome is a rare disorder that is characterized by anaerobic organisms inducing a thrombophlebitis of the internal jugular vein (IJV following a course of oropharyngeal infection. It often occurs in young and healthy patients. Clinicians continuously misinterpret early symptoms until infection disseminates systematically and life-threatening sepsis transpires. We report the case of a 58-year-old female developing Lemierre’s syndrome accompanied by invasive ventilation support and a profound deafness requiring the implementation of a cochlear implant. This is one of two reported cases of Lemierre’s syndrome associated with mechanical ventilation support and the only case associated with a cochlear implant.

    Leptin, the product of the Ob(Lep) gene, is a peptide hormone that plays a major role in maintaining the balance between food intake and energy expenditure. In the brain, leptin receptors are expressed by hypothalamic cells but also in the olfactory bulb, the first central structure coding for odors, suggesting a precise function of this hormone in odor-evoked activities. Although olfaction plays a key role in feeding behavior, the ability of the olfactory bulb to integrate the energy-related signal leptin is still missing. Therefore, we studied the fate of odor-induced activity in the olfactory bulb in the genetic context of leptin deficiency using the obese ob/ob mice. By means of an odor discrimination task with concomitant local field potential recordings, we showed that ob/ob mice perform better than wild-type (WT) mice in the early stage of the task. This behavioral gain of function was associated in parallel with profound changes in neuronal oscillations in the olfactory bulb. The distribution of the peaks in the gamma frequency range was shifted toward higher frequencies in ob/ob mice compared to WT mice before learning. More notably, beta oscillatory activity, which has been shown previously to be correlated with olfactory discrimination learning, was longer and stronger in expert ob/ob mice after learning. Since oscillations in the olfactory bulb emerge from mitral to granule cell interactions, our results suggest that cellular dynamics in the olfactory bulb are deeply modified in ob/ob mice in the context of olfactory learning.

  8. Profound loss of neprilysin accompanied by decreased levels of neuropeptides and increased CRP in ulcerative colitis.

    Full Text Available Neprilysin (NEP, CD10 acts to limit excessive inflammation partly by hydrolyzing neuropeptides. Although deletion of NEP exacerbates intestinal inflammation in animal models, its role in ulcerative colitis (UC is not well explored. Herein, we aimed to demonstrate changes in NEP and associated neuropeptides at the same time in colonic tissue. 72 patients with UC and 27 control patients were included. Patients' demographic data and laboratory findings, five biopsy samples from active colitis sites and five samples from uninvolved mucosa were collected. Substance P (SP, calcitonin gene related peptide (CGRP and vasoactive intestinal peptide (VIP were extracted from freshly frozen tissues and measured using ELISA. Levels of NEP expression were determined using immunohistochemistry and immunoreactivity scores were calculated. GEBOES grading system was also used. We demonstrated a profound loss (69.4% of NEP expression in UC, whereas all healthy controls had NEP expression. Patients with UC had lower neuronal SP; however non-neuronal SP remained similar. UC patients had also lower neuronal and non-neuronal VIP levels. CGRP were low in general and no significant changes were observed. Additionally, CRP positive patients with UC had higher rates of NEP loss (80% vs 51.9% and lower SP levels when compared with CRP negative patients with UC. Concurrent decreases in SP and VIP with profound loss of NEP expression observed in UC is likely to be one of the factors in pathogenesis. Further studies are required to define the role of neuropeptides and NEP in UC.

    Birth-related acute profound hypoxic-ischaemic brain injury has specific patterns of damage including the paracentral lobules. To test the hypothesis that there is anatomically coherent regional volume loss of the corpus callosum as a result of this hemispheric abnormality. Study subjects included 13 children with proven acute profound hypoxic-ischaemic brain injury and 13 children with developmental delay but no brain abnormalities. A computerised system divided the corpus callosum into 100 segments, measuring each width. Principal component analysis grouped the widths into contiguous anatomical regions. We conducted analysis of variance of corpus callosum widths as well as support vector machine stratification into patient groups. There was statistically significant narrowing of the mid-posterior body and genu of the corpus callosum in children with hypoxic-ischaemic brain injury. Support vector machine analysis yielded over 95% accuracy in patient group stratification using the corpus callosum centile widths. Focal volume loss is seen in the corpus callosum of children with hypoxic-ischaemic brain injury secondary to loss of commissural fibres arising in the paracentral lobules.

    Zied Riahi

    Full Text Available Usher syndrome (USH is an autosomal recessive disorder characterized by combined deafness-blindness. It accounts for about 50% of all hereditary deafness blindness cases. Three clinical subtypes (USH1, USH2, and USH3 are described, of which USH1 is the most severe form, characterized by congenital profound deafness, constant vestibular dysfunction, and a prepubertal onset of retinitis pigmentosa. We performed whole exome sequencing in four unrelated Tunisian patients affected by apparently isolated, congenital profound deafness, with reportedly normal ocular fundus examination. Four biallelic mutations were identified in two USH1 genes: a splice acceptor site mutation, c.2283-1G>T, and a novel missense mutation, c.5434G>A (p.Glu1812Lys, in MYO7A, and two previously unreported mutations in USH1G, i.e. a frameshift mutation, c.1195_1196delAG (p.Leu399Alafs*24, and a nonsense mutation, c.52A>T (p.Lys18*. Another ophthalmological examination including optical coherence tomography actually showed the presence of retinitis pigmentosa in all the patients. Our findings provide evidence that USH is under-diagnosed in Tunisian deaf patients. Yet, early diagnosis of USH is of utmost importance because these patients should undergo cochlear implant surgery in early childhood, in anticipation of the visual loss.

    Full Text Available Calcium and integrin-binding protein 2 (CIB2 belongs to a protein family with four known members, CIB1 through CIB4, which are characterized by multiple calcium-binding EF-hand domains. Among the family members, the Cib1 and Cib2 genes are expressed in mouse cochlear hair cells, and mutations in the human CIB2 gene have been associated with nonsyndromic deafness DFNB48 and syndromic deafness USH1J. To further explore the function of CIB1 and CIB2 in hearing, we established Cib1 and Cib2 knockout mice using the clustered regularly interspaced short palindromic repeat (CRISPR-associated Cas9 nuclease (CRISPR/Cas9 genome editing technique. We found that loss of CIB1 protein does not affect auditory function, whereas loss of CIB2 protein causes profound hearing loss in mice. Further investigation revealed that hair cell stereocilia development is affected in Cib2 knockout mice. Noticeably, loss of CIB2 abolishes mechanoelectrical transduction (MET currents in auditory hair cells. In conclusion, we show here that although both CIB1 and CIB2 are readily detected in the cochlea, only loss of CIB2 results in profound hearing loss, and that CIB2 is essential for auditory hair cell MET.

  13. Profound effects of population density on fitness-related traits in an invasive freshwater snail.

    Directory of Open Access Journals (Sweden)

    Nicholas Zachar

    Full Text Available Population density can profoundly influence fitness-related traits and population dynamics, and density dependence plays a key role in many prominent ecological and evolutionary hypotheses. Here, we evaluated how individual-level changes in population density affect growth rate and embryo production early in reproductive maturity in two different asexual lineages of Potamopyrgus antipodarum, a New Zealand freshwater snail that is an important model system for ecotoxicology and the evolution of sexual reproduction as well as a potentially destructive worldwide invader. We showed that population density had a major influence on individual growth rate and early-maturity embryo production, effects that were often apparent even when comparing treatments that differed in population density by only one individual. While individual growth rate generally decreased as population density increased, we detected a hump-shaped relationship between embryo production and density, with females from intermediate-density treatments producing the most embryos and females from low- and high-density treatments producing the fewest embryos. The two lineages responded similarly to the treatments, indicating that these effects of population density might apply more broadly across P. antipodarum. These results indicate that there are profound and complex relationships between population density, growth rate, and early-maturity embryo production in at least two lineages of this important model system, with potential implications for the study of invasive populations, research on the maintenance of sex, and approaches used in ecotoxicology.

    Full Text Available Phylogenetic profiling has been widely used for comparing bacterial communities, but has so far been impossible to apply to viruses because of the lack of a single marker gene analogous to 16S rRNA. Here we developed a reference tree approach for matching viral sequences and applied it to the largest viral datasets available. The resulting technique, Shotgun UniFrac, was used to compare host-associated and non-host-associated phage communities (130 total metagenomes, and revealed a profound split similar to that found with bacterial communities. This new informatics approach complements analysis of bacterial communities and promises to provide new insights into viral community dynamics, such as top-down versus bottom-up control of bacterial communities by viruses in a range of systems.

  18. Making Sense of Bereavement in People with Profound Intellectual and Multiple Disabilities: Carer Perspectives.

    2017-11-01

    People with intellectual disabilities are thought to have a reduced capacity for understanding death. Drawing on cognitive theory, researchers have suggested that those with profound intellectual and multiple disabilities mainly perceive loss as a mismatch between past and present experiences. However, very little research has considered how carers conceptualize bereavement in relation to this group. Semi-structured interviews obtained responses from seven carers. Transcripts were examined using interpretative phenomenological analysis. Two superordinate themes emerged: 'difficulty articulating the experience of loss' and 'making sense of bereavement through familiar patterns'. Carers conceptualize bereavement primarily in cognitive terms, but also take account of relational factors mediating loss. Implications for training and further research are outlined. © 2016 John Wiley & Sons Ltd.

  19. Care versus treatment at the end of life for profoundly disabled persons.

    2012-01-01

    Individuals who are profoundly mentally handicapped do not have the capacity to make their own decisions and also do not have a past record of decisions, from when they had capacity, to guide us in making decisions for them. They represent a difficult group, ethically, for surrogate decision making. Here I propose some guidelines, distinguishing between these patients and patients in a persistent vegetative state (PVS). As the life span of patients becomes shorter, or their level of consciousness becomes permanently impaired, the presumption for comfort care should become an imperative, and the standard of evidence to justify any invasive intervention should become higher. For members of this population, who have no more ability to refuse treatment than to consent to it, protection of the vulnerable must mean allowing a peaceful death as well as a comfortable life. Reasonable legal safeguards are also proposed to allow improved end-of-life decisions to be made for this population.

    OBJECTIVE: Cochlear implant (CI) treatment was introduced to the world in the 1980s and has become a routine treatment for congenital or acquired severe-to-profound hearing loss. CI treatment requires access to a highly skilled team of ear, nose and throat specialists, audiologists and speech...... years are in need of a CI every second year in Greenland often due to sequelae from meningitis, which may cause postinfectious deafness. Screening of new-borns for hearing has been started in Greenland establishing the basis for early diagnosis of congenital hearing impairment and subsequent...... intervention. The logistics and lack of availability of speech therapists in Greenland hampers possibilities for optimal language and speech therapy of CI patients in Greenland. This study aims at describing the results of CI treatment in Greenlanders and the outcome of the CI operations along...

    An emergency intervention was performed in a 75-year-old male patient with hypoglycemic attack and blackout. Although he was diagnosed with prediabetes before 2 years, he did not take any anti-diabetic drug or follow dietary advice. He drank Vaccinium corymbosum L (VC) juice daily with a belief that it increases sexual potency. Before the development of hypoglycemia, the patient had consumed about 500 ml VC juice in addition to eating 200-300 gram of Laurocerasus officinalis (LO) fruit. The measured plasma glucose (PG) level during loss of consciousness was 30 mg/dl. The profound hypoglycemia may be an unexpected side effect of an interaction between the chemical compositions of the two plants, occurred as a result of LO fruit intake that may have a strong PG-lowering effect or related to excessive intake of VC juice. Both plants may be considered in the alternative treatment of diabetes.

    Children with profound intellectual and multiple disabilities (PIMD) meet other children with PIMD in day care centres or schools. This study explores the peer-directed behaviours of children with PIMD, the peer interaction-influencing behaviour of the direct support workers and the children's positioning. Group activities for children with PIMD initiated by a direct support worker were video-recorded. The behaviour and positioning of the children and the behaviour of the direct support workers were coded. Limited peer-directed behaviour of the children with PIMD and peer interaction-influencing behaviour of the direct support workers are observed. Weak associations were found between the positioning or peer interaction-influencing behaviours and the behaviour of children with PIMD. Children with PIMD show social interest in each other during group activities. More knowledge is needed to create an environment which facilitates peer-directed behaviours of persons with PIMD. © 2015 John Wiley & Sons Ltd.

    To support people with profound intellectual and multiple disabilities (PIMD), it is essential to understand how they experience their environment. Insight into perception behaviour may provide an entry point for improved understanding. A random sample of a 30-min video registration of five participants with PIMD was used to code behaviours per second based on an ethogram containing 157 different perception behaviours in nine categories. Eighty-nine different perception behaviours were observed, of which movements with eyes, head and arms were most common. The senses used most were seeing, hearing and touching. Finally, the function of five perception patterns was established in relation to their function:awareness, focusing attention and tension regulation. Close observation using an observation ethogram provides insight into how people with PIMD perceive their environment. © 2017 John Wiley & Sons Ltd.

    Mental health problems affect people with intellectual disabilities (ID) at rates similar to or in excess of the non-ID population. People with severe ID are likely to have persistent mental health problems. In this systematic review (PROSPERO 2015:CRD42015024469), we identify and evaluate the methodological quality of available measures of mental health problems or well-being in individuals with severe or profound ID. Electronic searches of ten databases identified relevant publications. Two reviewers independently reviewed titles and abstracts of retrieved records (n=41,232) and full-text articles (n=573). Data were extracted and the quality of included papers was appraised. Thirty-two papers reporting on 12 measures were included. Nine measures addressed a broad spectrum of mental health problems, and were largely observational. One physiological measure of well-being was included. The Aberrant Behavior Checklist, Diagnostic Assessment for the Severely Handicapped Scale-II and Mood, Interest and Pleasure Questionnaire are reliable measures in this population. However, the psychometric properties of six other measures were only considered within a single study - indicating a lack of research replication. Few mental health measures are available for people with severe or profound ID, particularly lacking are tools measuring well-being. Assessment methods that do not rely on proxy reports should be explored further. Copyright © 2017 Elsevier Ltd. All rights reserved.

  5. Arogenate Dehydratase Isoenzymes Profoundly and Differentially Modulate Carbon Flux into Lignins*

    How carbon flux differentially occurs in vascular plants following photosynthesis for protein formation, phenylpropanoid metabolism (i.e. lignins), and other metabolic processes is not well understood. Our previous discovery/deduction that a six-membered arogenate dehydratase (ADT1–6) gene family encodes the final step in Phe biosynthesis in Arabidopsis thaliana raised the fascinating question whether individual ADT isoenzymes (or combinations thereof) differentially modulated carbon flux to lignins, proteins, etc. If so, unlike all other lignin pathway manipulations that target cell wall/cytosolic processes, this would be the first example of a plastid (chloroplast)-associated metabolic process influencing cell wall formation. Homozygous T-DNA insertion lines were thus obtained for five of the six ADTs and used to generate double, triple, and quadruple knockouts (KOs) in different combinations. The various mutants so obtained gave phenotypes with profound but distinct reductions in lignin amounts, encompassing a range spanning from near wild type levels to reductions of up to ∼68%. In the various KOs, there were also marked changes in guaiacyl:syringyl ratios ranging from ∼3:1 to 1:1, respectively; these changes were attributed to differential carbon flux into vascular bundles versus that into fiber cells. Laser microscope dissection/pyrolysis GC/MS, histochemical staining/lignin analyses, and pADT::GUS localization indicated that ADT5 preferentially affects carbon flux into the vascular bundles, whereas the adt3456 knock-out additionally greatly reduced carbon flux into fiber cells. This plastid-localized metabolic step can thus profoundly differentially affect carbon flux into lignins in distinct anatomical regions and provides incisive new insight into different factors affecting guaiacyl:syringyl ratios and lignin primary structure.

    The p-ADH level in cases of juvenile unilateral profound deafness (JUPD) and the timecourse of the level were examined to investigate whether or not an increase of p-ADH is involved in the development of delayed endolymphatic hydrops (DEH) in JUPD. In 90 consecutive patients with unilateral profound or total sensorineural deafness with the onset in early childhood, pure-tone audiometric examination and the measurement of p-ADH and plasma osmolality (p-OSM) were followed up once or twice a year as far as possible. At every testing, we performed careful history-taking about episodic vertigo/dizziness, fluctuant hearing loss, and tinnitus in order to find out whether patients had experienced these clinical signs of the development of DEH. Means and standard deviation (S.D.) of p-ADH level and osmolality in all samples tested (n=368) were 7.3+/-7.0 pg/mL (0.7-52.0 pg/mL), and 288.6+/-4.4 mOsm/L (273-306 mOsm/L), respectively. The mean of p-ADH level was much higher than those previously reported in children and adolescents. High levels of p-ADH (over 5.0 pg/mL) were often observed in subjects between 6 and 19 years of age, but not so frequently in subjects of 20 years of age or older. Long-term follow-up of p-ADH levels revealed that DEH frequently developed in cases with persistent elevation of p-ADH. The elevation of p-ADH is likely to promote the development of DEH in cases of JUPD, although the underlying mechanism remains to be elucidated.

  8. Expression and function of striatal enriched protein tyrosine phosphatase is profoundly altered in cerebral ischemia

    Striatal enriched protein tyrosine phosphatase (STEP) acts in the central nervous system to dephosphorylate a number of important proteins involved in synaptic function including ERK and NMDA receptor subunits. These proteins are also linked to stroke, in which cerebral ischemia triggers a complex cascade of events. Here we demonstrate that STEP is regulated at both the transcriptional and the post-transcriptional levels in rat models of cerebral ischemia and that its regulation may play a role in the outcome of ischemic insults. After transient middle cerebral artery occlusion, there are profound decreases in the levels of STEP mRNA, whilst in global ischemia STEP mRNA is selectively down-regulated in areas susceptible to ischemic damage. In a neuroprotective preconditioning paradigm, and in regions of the brain that are relatively resistant to ischemic damage, STEP mRNA levels are increased. Furthermore, there is a significant processing of STEP after ischemia to generate a novel species, STEP33, resulting in a redistribution of STEP from membrane-bound to soluble compartments. Concomitant with the cleavage of mature forms of STEP, there are changes in the phosphorylation state of ERK. We show that the cleavage of STEP leads to a catalytically active form, but this cleaved form no longer binds to and dephosphorylates its substrate pERK. Therefore, in response to ischemic insults, there are profound reductions in both the amount and the activity of STEP, its localization, as well as the activity of one of its key substrates, pERK. These changes in STEP may reflect a critical role in the outcomes of ischemic brain injury. PMID:18445231

    Hypermobility-type Ehlers-Danlos syndrome (EDS), an often-missed diagnosis with the potential for serious sequelae, may have a variety of uncommon presentations, some of which may be gynecologic. The aim of this case report is to present two cases of profound labial edema associated with intercourse as a presenting symptom of hypermobility-type EDS. A 25-year-old female presented with severe labia minora swelling and bladder pressure associated with intercourse, in addition to persistent genital arousal. History revealed easy bruising, joint pain, and family history of aneurysm. A 22-year-old female presented with intermittent profound labial swelling for 6 years, associated with sensitivity and pain with intercourse. The patient has a history of joint pain and easy bruising, as well a sister with joint hypermobility and unexplained lymphedema. The presenting symptom of profound labial edema led to the diagnosis of hypermobility-type EDS. Patients with hypermobility syndrome exhibit an increased ratio of type III collagen to type I collagen, causing tissue laxity and venous insufficiency. Abnormal collagen may lead to gynecologic manifestations, including unexplained profound labial edema, pelvic organ prolapse in the absence of risk factors, and possibly persistent genital arousal. This case report highlights the need for further research to determine incidence of labial edema in hypermobility-type EDS and to further elucidate a potential correlation between profound labial edema and collagen disorders. © 2013 International Society for Sexual Medicine.

    2015-01-01

    We reviewed 18 studies reporting on the use of microswitch technology to enable self-determined responding in children with profound and multiple disabilities. Identified studies that met pre-determined inclusion criteria were summarized in terms of (a) participants, (b) experimental design, (c) microswitches and procedures used, and (d) main results. The 18 studies formed three groups based on whether the microswitch technology was primarily intended to enable the child to (a) access preferred stimuli (7 studies), (b) choose between stimuli (6 studies), or (c) recruit attention/initiate social interaction (5 studies). The results of these studies were consistently positive and support the use of microswitch technology in educational programs for children with profound and multiple disabilities as a means to impact their environment and interact with others. Implications for delivery of augmentative and alternative communication intervention to children with profound and multiple disabilities are discussed.

    Although trait choice is crucial to quantify functional diversity appropriately, the quantitative methods for it are rarely compared and discussed. Meanwhile, very little is known about how trait choice affects ecological conclusions drawn from functional diversity measures. We presented the four methods of trait selection as alternatives to the ordination axis-based method, which directly identify a subset of key traits to represent the main variation of all the traits. To evaluate their performance, we compared the closeness of association obtained by different methods between species richness and functional diversity indices (FAD, FD, Q, FDis) in the six ecosystems. The evaluation was also benchmarked against the results obtained by calculating the possible indices using all the trait combinations (the complete search method). We found that the trait selection methods were potential alternatives to axis-based method to gain a mechanistic understanding of functional responses and effects of traits, while these methods as well as the axis-based method possibly use mismatched information to interpret the investigated ecosystem properties. Trait choice profoundly affected the ecological conclusions drawn from functional diversity measures. The complete search method should be used to assess the rationale of different trait choice methods and the quality of the calculated indices.

    Postnatal size changes in most vertebrates are unidirectional and finite once the individual reaches full size [1]. In rare cases, changes of body length may occur in response to harsh environmental conditions. Such reactionary changes are distinct from seasonal, often anticipatory morphological changes, such as the reversible size change of some adult bird brains [2]. A unique pattern of profound anatomical change known as Dehnel's phenomenon has been described for the body, skull and brain size of red-toothed shrews and some mustelids [3-5]. The seasonal 20% decrease and 15% re-growth of the most common proxy, braincase height, were documented at population level from extracted skulls post-mortem. Quantifying intra-individual change had so far been methodologically prohibitive. Here, we followed the intra-individual change in skull size and body mass throughout the full cycle in wild recaptured shrews (Sorex araneus). Using X-ray images we showed that individuals decreased the size of their braincases in anticipation of winter by an average of 15.3%. Braincases then partially regrew in spring by 9.3%. Body mass decreased by 17.6% and then dramatically increased by 83.4% in spring. Thus, we demonstrate that the dramatic changes incurred by Dehnel's phenomenon occur in the individual's bone and other tissues. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Although, the association between Down syndrome (DS) and conductive hearing loss is well recognized, the fact that a small proportion of these children may have a severe to profound sensorineural hearing loss that could benefit from cochlear implantation (CI) is less well understood. The management of significant co-morbidities in children with DS can delay initial diagnosis of hearing impairment and assessment of suitability for CI can likewise be challenging, due to difficulties conditioning to behavioural hearing tests. We performed a retrospective case note review of three children with DS referred to the Manchester Cochlear Implant Programme. Three illustrative cases are described including CI in a 4 years old. Using conventional outcome measurement instruments, the outcome could be considered to be suboptimal with a Categories of Auditory Performance score of 4 at 6 months post-op and at last follow up. In part, this is likely to reflect the delay in implantation, but the role of cognitive impairment must be considered. The cases described emphasize the importance of comprehensive radiological and audiological assessment in children with DS being considered for CI. The influence of cognitive impairment upon outcome of CI must be taken into account, but should not be considered a contra-indication to implantation in children with DS. Benefit that might be considered limited when quantified using existing general outcome measurement instruments, may have a significant impact upon psychosocial development and quality of life in children with significant cognitive impairment, or other additional needs.

    Background: Patients with recurrent glioblastoma have a poor outcome. Data from the phase III registration trial comparing tumour-treating alternating electric fields (TTFields) vs chemotherapy provided a unique opportunity to study dexamethasone effects on patient outcome unencumbered by the confounding immune and myeloablative side effects of chemotherapy. Methods: Using an unsupervised binary partitioning algorithm, we segregated both cohorts of the trial based on the dexamethasone dose that yielded the greatest statistical difference in overall survival (OS). The results were validated in a separate cohort treated in a single institution with TTFields and their T lymphocytes were correlated with OS. Results: Patients who used dexamethasone doses >4.1 mg per day had a significant reduction in OS when compared with those who used ⩽4.1 mg per day, 4.8 vs 11.0 months respectively (χ2=34.6, Pdexamethasone >4.1 mg per day was 3.2 months compared with those who used ⩽4.1 mg per day was 8.7 months (χ2=11.1, P=0.0009). There was a significant correlation between OS and T-lymphocyte counts. Conclusions: Dexamethasone exerted profound effects on both TTFields and chemotherapy efficacy resulting in lower patient OS. Therefore, global immunosuppression by dexamethasone likely interferes with immune functions that are necessary for the treatment of glioblastoma. PMID:26125449

    Full Text Available Introduction: A case of profound weight loss after gastric bypass surgery with multiple negative evaluations. Case presentation: A 41-year-old African-American female presented with greater-than-expected weight loss after gastric bypass and increasing abdominal pain over a 2-year period. An extensive workup was pursued for the patient with blood analysis, tumor markers, imaging studies both computed tomography and magnetic resonance imaging, arterial studies, and endoscopy from above and below, all of which demonstrated normal results. The patient was followed up without improvement, and repeated studies were also normal. The patient was labeled with a nonorganic etiology for her symptoms, which led to a psychiatry referral which was refused. Conclusion: The patient’s surgeon, who already had removed a normal appendix and gallbladder, repeated a laparoscopic exam. The exam was normal except for a small focus of pancreatic cancer in the celiac plexus. The patient died from perioperative sepsis from peritonitis 2 days after surgery. The case is discussed and findings reviewed.

    GJB2 mutations are responsible not only for deafness but also for the occurrence of vestibular dysfunction. However, vestibular dysfunction tends to be unilateral and less severe in comparison with that of bilateral deafness. The correlation between the cochlear and vestibular end-organs suggests that some children with congenital deafness may have vestibular impairments. On the other hand, GJB2 gene mutations are the most common cause of nonsyndromic deafness. The vestibular function of patients with congenital deafness (CD), which is related to GJB2 gene mutation, remains to be elucidated. The purpose of this study was to analyze the relationship between GJB2 gene mutation and vestibular dysfunction in adults with CD. A total of 31 subjects, including 10 healthy volunteers and 21 patients with CD, were enrolled in the study. A hearing test and genetic analysis were performed. The vestibular evoked myogenic potentials (VEMPs) were measured and a caloric test was performed to assess the vestibular function. The percentage of vestibular dysfunction was then statistically analyzed. The hearing level of all CD patients demonstrated a severe to profound impairment. In seven CD patients, their hearing impairment was related to GJB2 mutation. Five of the seven patients with CD related to GJB2 mutation demonstrated abnormalities in one or both of the two tests. The percentage of vestibular dysfunction of the patients with CD related to GJB2 mutation was statistically higher than in patients with CD unrelated to GJB2 mutation and in healthy controls.

  18. Holding Ashley (X): Bestowing Identity Through Caregiving in Profound Intellectual Disability.

    2017-01-01

    The controversy over the so-called Ashley Treatment (AT), a series of medical procedures that inhibited both growth and sexual development in the body of a profoundly intellectually impaired girl, usually centers either on Ashley's rights, including a right to an intact, unaltered body, or on Ashley's parents' rights to make decisions for her. The claim made by her parents, that the procedure would improve their ability to care for her, is often dismissed as inappropriate or, at best, irrelevant. We argue, however, that caregiving is a central issue in the controversy, as Ashley's need for caregiving is a defining characteristic of her life. In this article, we analyze the ethics of the Ashley Treatment within the context of family caregiving. Through the physical and emotional work of caregiving, families participate in the formation and maintenance of personal identity, a process that Hilde Lindemann recently called "holding." We argue that, in an intellectually disabled person such as Ashley, who depends on her family for every aspect of her care, the family's contribution to identity is an essential source of personhood. We believe that the treatment can be justified if it is indeed an instance of appropriate family "holding" for Ashley. Copyright 2017 The Journal of Clinical Ethics. All rights reserved.

    Malaria during pregnancy constitutes a large health problem in endemic areas. WHO recommends that interventions are initiated at the first antenatal visit, and these improve pregnancy outcomes. This study evaluated foetal growth by ultrasound and birth outcomes in women who were infected prior to the first antenatal visit (gestational age, GApregnancy. Compared to uninfected controls, women with early P. falciparum exposure had retarded intrauterine growth between a GA of 212 and 253 days (mean weight gain reduction: 107g [26;188], P=0.0099) and shorter pregnancy length (mean reduction 6.6 days [1.0;112.5], P=0.0087). The birth weight (mean reduction 221g [6;436], P=0.044) and the placental weight (mean reduction 84g ([18; 150], P=0.013) at term were also reduced. The study suggests that early exposure to P. falciparum, which are not prevented by current control strategies, has profound impact on foetal growth, pregnancy length and the placental weight at term. © The Author 2017.

  20. Achieving and sustaining profound institutional change in healthcare: case study using neo-institutional theory.

    2013-03-01

    Change efforts in healthcare sometimes have an ambitious, whole-system remit and seek to achieve fundamental changes in norms and organisational culture rather than (or as well as) restructuring the service. Long-term evaluation of such initiatives is rarely undertaken. We report a secondary analysis of data from an evaluation of a profound institutional change effort in London, England, using a mixed-method longitudinal case study design. The service had received £15 million modernisation funding in 2004, covering multiple organisations and sectors and overseen by a bespoke management and governance infrastructure that was dismantled in 2008. In 2010-11, we gathered data (activity statistics, documents, interviews, questionnaires, site visits) and compared these with data from 2003 to 2008. Data analysis was informed by neo-institutional theory, which considers organisational change as resulting from the material-resource environment and three 'institutional pillars' (regulative, normative and cultural-cognitive), enacted and reproduced via the identities, values and activities of human actors. Explaining the long-term fortunes of the different components of the original programme and their continuing adaptation to a changing context required attention to all three of Scott's pillars and to the interplay between macro institutional structures and embedded human agency. The paper illustrates how neo-institutional theory (which is typically used by academics to theorise macro-level changes in institutional structures over time) can also be applied at a more meso level to inform an empirical analysis of how healthcare organisations achieve change and what helps or hinders efforts to sustain those changes.

    2016-02-01

    Full Text Available Background: The Western Cape Forum for Intellectual Disability took the South African Government to court in 2010 on its failure to implement the right to education for Children with Severe and Profound Intellectual Disability. Subsequently, multidisciplinary teams were appointed by the Western Cape Education Department to deliver services to the Special Care Centres (SCCs. Initially, minimal information was available on this population.Objectives: The purpose is to document the process of developing and validating a database for the collection of routine data.Method: A descriptive analytical study design was used. A sample of convenience was drawn from individuals under the age of 18 years, enrolled in SCCs in the Western Cape. The team who entered and analysed the data reached consensus regarding the utility and feasibility of each item.Results: Data were collected on 134 children. The omission of certain items from the database was identified. Some information was not reliable or readily available. Of the instruments identified to assess function, the classification systems were found to be reliable and useful, as were the performance scales. The WeeFIM, on the other hand, was lengthy and expensive, and was therefore discarded.Discussion and conclusions: A list of items to be included was identified. Apart from an individual profile, it can be useful for service planning and monitoring, if incorporated into the central information system used to monitor the performance of all children. Without such inclusion, this most vulnerable population, despite court ruling, will not have their right to education adequately addressed.

  2. RhoE deficiency produces postnatal lethality, profound motor deficits and neurodevelopmental delay in mice.

    Directory of Open Access Journals (Sweden)

    Enric Mocholí

    Full Text Available Rnd proteins are a subfamily of Rho GTPases involved in the control of actin cytoskeleton dynamics and other cell functions such as motility, proliferation and survival. Unlike other members of the Rho family, Rnd proteins lack GTPase activity and therefore remain constitutively active. We have recently described that RhoE/Rnd3 is expressed in the Central Nervous System and that it has a role in promoting neurite formation. Despite their possible relevance during development, the role of Rnd proteins in vivo is not known. To get insight into the in vivo function of RhoE we have generated mice lacking RhoE expression by an exon trapping cassette. RhoE null mice (RhoE gt/gt are smaller at birth, display growth retardation and early postnatal death since only half of RhoE gt/gt mice survive beyond postnatal day (PD 15 and 100% are dead by PD 29. RhoE gt/gt mice show an abnormal body position with profound motor impairment and impaired performance in most neurobehavioral tests. Null mutant mice are hypoactive, show an immature locomotor pattern and display a significant delay in the appearance of the hindlimb mature responses. Moreover, they perform worse than the control littermates in the wire suspension, vertical climbing and clinging, righting reflex and negative geotaxis tests. Also, RhoE ablation results in a delay of neuromuscular maturation and in a reduction in the number of spinal motor neurons. Finally, RhoE gt/gt mice lack the common peroneal nerve and, consequently, show a complete atrophy of the target muscles. This is the first model to study the in vivo functions of a member of the Rnd subfamily of proteins, revealing the important role of Rnd3/RhoE in the normal development and suggesting the possible involvement of this protein in neurological disorders.

    The available opinions regarding participation do not appear to be applicable to adults with visual and severe or profound intellectual disabilities (VSPID). Because a clear definition and operationalization are lacking, it is difficult for support professionals to give meaning to participation for adults with VSPID. The purpose of the present study was to develop a definition and operationalization of the concept of participation of adults with VSPID. Parents or family members, professionals, and experts participated in an online concept mapping procedure. This procedure includes generating statements, clustering them, and rating their importance. The data were analyzed quantitatively using multidimensional scaling and qualitatively with triangulation. A total of 53 participants generated 319 statements of which 125 were clustered and rated. The final cluster map of the statements contained seven clusters: (1) Experience and discover; (2) Inclusion; (3) Involvement; (4) Leisure and recreation; (5) Communication and being understood; (6) Social relations; and (7) Self-management and autonomy. The average importance rating of the statements varied from 6.49 to 8.95. A definition of participation of this population was developed which included these seven clusters. The combination of the developed definition, the clusters, and the statements in these clusters, derived from the perceptions of parents or family members, professionals, and experts, can be employed to operationalize the construct of participation of adults with VSPID. This operationalization supports professionals in their ability to give meaning to participation in these adults. Future research will focus on using the operationalization as a checklist of participation for adults with VSPID. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The importance of a partnership between parents and professionals in the support of children with disabilities is widely acknowledged and is one of the key elements of 'family-centred care'. To what extent family-centred principles are also applied to the support of persons with profound intellectual and multiple disabilities (PIMD) is not yet known. The purpose of this exploratory study was to examine what parents with a child with PIMD find important in the support of their child. In addition, we examined which child or parent characteristics influence these parental opinions. In total, 100 parents completed an adapted version of the Measure of Processes of Care. Mean unweighted and weighted scale scores were computed. Non-parametric tests were used to examine differences in ratings due to child (gender, age, type and number of additional disabilities, type of services used and duration of service use) and parent characteristics (gender, involvement with support and educational level). Parents rated situations related to 'Respectful and Supportive Care' and 'Enabling and Partnership' with averages of 7.07 and 6.87 respectively on a scale from 1 to 10. They were generally satisfied with the services provided, expressed in a mean score of 6.88 overall. The age of the child significantly affected the scores for 'Providing Specific Information about the Child'. Parents of children in the '6-12 years' age group gave significantly higher scores on this scale than did parents of children in the '≥17 years' age group (U = 288, r = -0.34). This study shows that parents with children with PIMD find family-centred principles in the professional support of their children important. Although the majority of parents are satisfied with the support provided for their children, a substantial minority of the parents indicated that they did not receive the support they find important. © 2012 Blackwell Publishing Ltd.

  5. Risk factors associated with challenging behaviour in people with profound intellectual and multiple disabilities.

    Several factors that correlate with the onset or continuation of challenging behaviour are mentioned in research. These are factors related to persons with ID, but also to direct support professionals and the context. Although many of these factors seem to affect the onset or continuation of challenging behaviour in people with ID in general, results are often inconclusive and have little focus on people with profound intellectual and multiple disabilities (PIMD). The present study aimed to assess the extent to which known factors related to challenging behaviour are also applicable to a group of 198 people with PIMD. To determine which factors were associated with challenging behaviour, univariate analyses on associations between known risk factors and challenging behaviour were conducted. The associated factors were then subject to a regression analysis to determine the extent to which they explain the prevalence of challenging behaviour and can thus be seen as factors associated with challenging behaviour. The results show that, in particular, factors concerning the personal characteristics of people with PIMD, such as sleeping problems and auditory problems, were related to the variance in mean frequency of challenging behaviour. Only one factor related to the direct support professionals was found: when these professionals had been offered training on the subject of challenging behaviour in people with intellectual disabilities in general, they identified significantly more withdrawn behaviour. We found no contextual factors related to challenging behaviour. These findings are generally consistent with findings reported in other studies, especially concerning the personal characteristics of people with PIMD. Further research should focus on the effects of providing safe auditory environments and appropriate sleep schedules for people with PIMD on the occurrence of challenging behaviour. © 2016 MENCAP and International Association of the Scientific Study of

  6. Initiation of activities and alertness in individuals with profound intellectual and multiple disabilities.

    When providing activities to individuals with profound intellectual and multiple disabilities (PIMD), direct support persons (DSPs) often face questions that are, among other things, related to the alertness of the person with PIMD. While previous studies have revealed that stimulation might have a greater impact on levels of alertness than the internal conditions of the individual, they have also emphasized the importance of interaction in order to influence the level of alertness. Because the initiation of this interaction has been described as one of its core components, the present study has focused on the relationship between the stimuli presented, the initiation of the activity (by the person with PIMD or the DSP), and the level of alertness of the person with PIMD. Videotapes of the one-to-one interactions of 24 individuals with PIMD and their DSPs in multisensory environments have been scored using the Alertness Observation List. In a sequential analysis, the percentages of stimuli presented were related to the percentages of initiation. Furthermore, two other analyses focused on the relationship between the level of alertness and the preceding and subsequent percentages of initiation respectively. The results show that high percentages of the activities are initiated by the DSPs. In addition, activities that were initiated by the individual with PIMD were preceded and followed by higher percentages of alert behaviour than those initiated by the DSP. Outcomes differed for the different types of stimuli. These results have striking implications for the lives of individuals with PIMD. It is quite possible that DSPs often act too quickly, whereas they would be better off waiting for a reaction on the part of their client. In general, DSPs need to find a balance between being passive themselves and promoting in the individual with PIMD a state of being as active and alert as possible. © 2014 MENCAP and International Association of the Scientific Study of

    Raising children with severe or profound intellectual and multiple disabilities (PIMD) is expected to put extreme pressure on parental time use patterns. The aim of this study was to examine the total time use of mothers and fathers raising children with PIMD and compare it with the time use of parents of typically developing children. Twenty-seven fathers and 30 mothers raising children with PIMD completed a time use diary on a mobile phone or tablet app, as did 66 fathers and 109 mothers of typically developing children. Independent t-tests and Mann-Whitney tests were performed to compare mean time use. There are no differences in the time use of parents of children with PIMD on contracted time (paid work and educational activities) and necessary time (personal care, eating and drinking and sleeping) when compared with parents of typically developing children. There are significant differences between the parents of children with PIMD and the parents of typically developing children in terms of committed time (time for domestic work and the care and supervision of their children) and free time. The mothers of children with PIMD spend significantly less time on domestic work and more time on care and supervision than mothers of typically developing children. This study shows that the parents of children with PIMD have to spend a significant amount of time on care tasks and have on average 1.5 h less free time per day than parents of typically developing children. This is a striking difference, because leisure time can substantially contribute to well-being. Therefore, it is important not only to consider a child with PIMD's support needs but also to identify what parents need to continue their children's daily care and supervision. © 2017 John Wiley & Sons Ltd.

  8. NATURE FACILITATES CONNECTION WITH THE PROFOUND SELF: NEEDS, GOALS AND RESOURCE AWARENESS

    2014-11-01

    Full Text Available The present study is based on Kaplan and Kaplan’s (1989 theory explaining the restorative effects that nature has on a person’s psychic. According to this theory, nature exerts a “soft fascination” combining the activation of involuntary attention mechanisms with the reflexive awareness, allowing a spontaneous detachment from stress factors and automatic functioning, and also the feeling of compatibility between personal purposes, and the possibilities for action offered by the environment (a sense of meaning. Our objective was to investigate the effects of nature on Self awareness: the immediate, emotional experience; needs awareness and organization; plans for action, and availability of resources, both personal, and external. We conducted an experiment with an experimental group (persons watching a video with life in nature and an active control group (involved in a psychotherapeutic technique focused on confronting and solving personal difficulties by creative means, accompanied by a short psychological analysis. The effects were assessed in terms of “here and now” emotions and available resources according to a self-evaluation scale, and with open-ended questions regarding personal needs and goals. The results showed that, for the experimental group, the relaxation effects and the awareness of long term goals were stronger, while all the other effects were the same as for the control group. The results suggest that indeed, nature helps a person get in contact with her profound Self, allowing the access to both “here and now” basic needs, and also long term goals (inner sources of meaning, the sense of connection between internal tendencies, personal, and external resources, resulting in increased positive emotions, and decreased negative emotions. Nature contemplation may facilitate a meditative state whit all its positive effects.

    To highlight Noonan syndrome as a clinically recognizable cause of severe to profound sensorineural hearing impairment. New clinical cases and review. Patients evaluated for etiological diagnosis by a medical geneticist in a reference center for hearing impairment. Five patients presenting with confirmed Noonan syndrome and profound sensorineural hearing impairment. Diagnostic and review of the literature. Five patients presented with profound sensorineural hearing impairment and molecularly confirmed Noonan syndrome. Sensorineural hearing impairment has been progressive for three patients. Cardiac echography identified pulmonary stenosis in two patients and was normal for the three other patients. Short stature was found in two patients. Mild intellectual disability was found in one patient. Inconspicuous clinical features as facial dysmorphism, cryptorchidism, or easy bruising were of peculiar interest to reach the diagnosis of Noonan syndrome. Profound sensorineural hearing impairment can be the main feature of Noonan syndrome. Associated features are highly variable; thus, detailed medical history and careful physical examination are mandatory to consider the diagnosis in case of a sensorineural hearing impairment.

  6. Mouse background strain profoundly influences Paneth cell function and intestinal microbial composition.

    Directory of Open Access Journals (Sweden)

    Ajay S Gulati

    Full Text Available Increasing evidence supports the central role of Paneth cells in maintaining intestinal host-microbial homeostasis. However, the direct impact of host genotype on Paneth cell function remains unclear. Here, we characterize key differences in Paneth cell function and intestinal microbial composition in two widely utilized, genetically distinct mouse strains (C57BL/6 and 129/SvEv. In doing so, we demonstrate critical influences of host genotype on Paneth cell activity and the enteric microbiota.Paneth cell numbers were determined by flow cytometry. Antimicrobial peptide (AMP expression was evaluated using quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR, acid urea-polyacrylamide gel electrophoresis, and mass spectrometry. Effects of mouse background on microbial composition were assessed by reciprocal colonization of germ-free mice from both background strains, followed by compositional analysis of resultant gut bacterial communities using terminal restriction fragment length polymorphism analysis and 16 S qPCR. Our results revealed that 129/SvEv mice possessed fewer Paneth cells and a divergent AMP profile relative to C57BL/6 counterparts. Novel 129/SvEv á-defensin peptides were identified, including Defa2/18v, Defa11, Defa16, and Defa18. Host genotype profoundly affected the global profile of the intestinal microbiota, while both source and host factors were found to influence specific bacterial groups. Interestingly, ileal α-defensins from 129/SvEv mice displayed attenuated antimicrobial activity against pro-inflammatory E. coli strains, a bacterial species found to be expanded in these animals.This work establishes the important impact of host genotype on Paneth cell function and the composition of the intestinal microbiota. It further identifies specific AMP and microbial alterations in two commonly used inbred mouse strains that have varying susceptibilities to a variety of disorders, ranging from obesity to intestinal

    2015-01-01

    The value of cochlear implants (CI) in patients with profound unilateral hearing loss (UHL) and tinnitus has recently been investigated. The authors previously demonstrated the feasibility of CI in a 12- month outcome study in a prospective UHL cohort. The aim of this study was to investigate the binaural auditory outcomes in this cohort 36 months after CI surgery. The 36-month outcome was evaluated in 22 CI users with postlingual UHL and severe tinnitus. Twelve subjects had contralateral normal hearing (single-sided deafness - SSD group) and 10 subjects had a contralateral, mild to moderate hearing loss and used a hearing aid (asymmetric hearing loss - AHL group). Speech perception in noise was assessed in two listening conditions: the CIoff and the CIon condition. The binaural summation effect (S0N0), binaural squelch effect (S0NCI) and the combined head shadow effect (SCIN0) were investigated. Subjective benefit in daily life was assessed by means of the Speech, Spatial and Qualities of Hearing Scale (SSQ). At 36 months, a significant binaural summation effect was observed for the study cohort (2.00, SD 3.82 dB; p binaural effect was not significant 12 months after CI surgery. A binaural squelch effect was significant for the AHL subgroup at 12 months (2.00, SD 4.38 dB; p < 0.05). A significant combined head shadow and squelch effect was also noted in the spatial configuration SCIN0 for the study cohort (4.00, SD 5.89 dB; p < 0.01) and for the AHL subgroup (5.67, SD 6.66 dB; p < 0.05). The SSQ data show that the perceived benefit in daily life after CI surgery remains stable up to 36 months at CIon. CI can significantly improve speech perception in noise in patients with UHL. The positive effects of CIon speech perception in noise increase over time up to 36 months after CI surgery. Improved subjective benefit in daily life was also shown to be sustained in these patients. © 2015 S. Karger AG, Basel.

    Full Text Available Objective. Cochlear implant (CI treatment was introduced to the world in the 1980s and has become a routine treatment for congenital or acquired severe-to-profound hearing loss. CI treatment requires access to a highly skilled team of ear, nose and throat specialists, audiologists and speech-language pathologists for evaluation, surgery and rehabilitation. In particular, children treated with CI are in need of long-term post-operative auditory training and other follow-up support. Design. The study is retrospective with updated information on present performance. Results. Since 2001, a total of 11 Greenlandic patients living in Greenland have been treated with CI, 7 children and 4 adults. Of these children, 4 use oral communication only and are full-time CI-users, 2 with full-time use of CI are still in progress with use of oral communication, and 1 has not acquired oral language yet, but has started auditory and speech training. Six children attend mainstream public school while one child is in kindergarten. Of the adults, only 1 has achieved good speech perception with full-time use of CI while 3 do not use the CI. Discussion. From an epidemiological point of view, approximately 1–3 children below 6 years are in need of a CI every second year in Greenland often due to sequelae from meningitis, which may cause postinfectious deafness. Screening of new-borns for hearing has been started in Greenland establishing the basis for early diagnosis of congenital hearing impairment and subsequent intervention. The logistics and lack of availability of speech therapists in Greenland hampers possibilities for optimal language and speech therapy of CI patients in Greenland. This study aims at describing the results of CI treatment in Greenlanders and the outcome of the CI operations along with the auditory and speech/language outcomes. Finally, we present a suggestion for the future CI treatment and recommendations for an increased effort in the

    Specialized strategies are needed to understand the complex neuropsychological impairments reported in individuals with profound intellectual and multiple disabilities (PIMD) associated with rare genetic disorders. This narrative review focuses on assessment of individuals with Phelan-McDermid Syndrome (PMS) as a condition commonly associated with PIMD. Published case series and prospective studies were reviewed to evaluate approaches to cognitive, language, motor/sensory, and behavioral domains. This review is framed using general principles for neuropsychological evaluation in PIMD. Neuropsychological assessment domains and tools varied across published reports. Adaptive behavior measures, out-of-range developmental assessments, and social-communication measures were commonly used. Available findings were used to shape a recommended framework with potential to improve measurement of clinical outcomes and advance scientific discovery. The recommended framework outlines an inter-disciplinary and multimodal neuropsychological assessment process relying on modified standardized assessments, functional assessments, and caregiver/informant reports when evaluating individuals with PIMD. Arrested development and skill variability/regression are also discussed as additional, important considerations in neuropsychological evaluation of individuals with PIMD and rare genetic disorders.

    1997-06-01

    This paper is an investigation into the efficacy of four therapeutic treatment procedures increasingly used with people with profound learning disabilities: snoezelen, hand massage/aromatherapy, relaxation, and active therapy (a bouncy castle). In particular, the effects of these procedures on concentration and responsiveness were examined. Eight subjects with profound learning disabilities took part in the study and each subject received each of the treatments. To assess the effects of the treatments, simple concentration tasks were administered and the subjects' responsiveness to each treatment was rated by independent observers. The results suggest that both snoezelen and relaxation had a positive effect on concentration and seemed to be the most enjoyable therapies for clients, whereas hand massage/aromatherapy and active therapy had no or even negative effects on concentration and appeared less enjoyable.

    2000-10-01

    This paper reports an unusual case in which acute lymphocytic leukemia presented acute profound sensorineural hearing loss as the initial manifestation of the disease. The patient is a 55-year-old woman who complained of left hearing loss of sudden onset. Pure tone audiometry revealed profound sensorineural hearing loss of the left ear at mid and low frequencies. The patient was tentatively diagnosed as idiopathic sudden deafness and admitted for the treatment, but her laboratory data indicated that she was at an advanced stage of leukemia. The patient's hearing loss did not improve subjectively until she deceased 1 year after the admission. The mechanism producing acute hearing loss in leukemic patients is reviewed and discussed, and the importance of differentiating possible underlying diseases before we diagnose idiopathic sudden deafness is stressed.

    Full Text Available This paper argues that in addressing and managing profound suffering at the end-of-life, the priority should not be the legalization of physician-assisted suicide or voluntary active euthanasia in jurisdictions where these practices are not currently available. Rather, concerted efforts should be made by society and the healthcare provider community to expand patient access to proportionate distress-relieving sedation and continuous deep sedation.

  15. Case report: profound hypotension associated with labetalol therapy in a patient with cerebral aneurysms and subarachnoid hemorrhage.

    Labetalol is an effective antihypertensive medication frequently used to treat systemic hypertension in acute care settings, including the management of hypertension associated with a subarachnoid hemorrhage. We present a case of profound hypotension, refractory to inotropic and vasopressor therapy following an iv infusion of labetalol. Initiation of an iv labetalol infusion resulted in good blood pressure control in a patient suffering from a Fisher grade 3 subarachnoid hemorrhage with an initial Glascow coma scale of 14/15 and mild hydrocephalus. Progressive deterioration of neurological symptoms and evidence of worsening hydrocephalus preceded the sudden development of profound hypotension (60/35 mmHg) and bradycardia with a minimum heart rate of 40 beats.min(-1). Initial resuscitative efforts included administration of intravascular fluid, hypertonic saline, atropine, adrenalin (more than 10 mg in divided doses) and noradrenalin. These measures restored the blood pressure to 80/45 with a HR of 98 beats.min(-1). Intraoperative placement of an intraventricular drain released cerebrospinal fluid under pressure with an initial intracranial pressure of 15 cm H(2)O. A combination of adrenalin, noradrenalin, dopamine and vasopressin infusions were required to restore the blood pressure to 130/65 mmHg after an additional two hours. All inotropic and vasopressor support was weaned off after the 14th hr (about two drug half-lives). The patient was awake and responsive the following day, with no obvious neurological consequences. No evidence of neurological injury, drug administration error or myocardial dysfunction was documented. The episode of profound hypotension which occurred after initiating a labetolol infusion required maximal combined vasopressor therapy to restore the blood pressure suggesting that this patient demonstrated an extreme sensitivity to labetalol. Combination therapy with adrenergic and nonadrenergic agonists may be required for optimal treatment

    This study aimed to determine the low- and high-frequency compression ratios of a fast-acting device that were preferred by people with moderately severe to profound hearing loss. Three compression ratios (1:1, 1.8:1, and 3:1) were combined in the low and high frequencies to produce nine schemes that were evaluated pair-wise for three weeks in the field using an adaptive procedure. The evaluation was performed by 21 experienced hearing aid users with a moderately severe to profound hearing loss. Diaries and an exit interview were used to monitor preferences. Generally, the subjects preferred lower compression ratios than are typically prescribed, especially in the low frequencies. Specifically, 11 subjects preferred linear amplification in the low frequencies, and 14 subjects preferred more compression in the high than in the low frequencies. Preferences could not be predicted from audiometric data, onset of loss, or past experience with amplification. The data suggest that clients with moderately severe to profound hearing loss should be fitted with low-frequency compression ratios in the range 1:1 to 2:1 and that fine-tuning is essential.

  17. 372 Profound Lack of Nonclinical Health Care Aptitude Across a Range of Health Care Providers and Students.

    2016-08-01

    American health care continues to undergo profound changes at a breakneck speed. Future challenges show no signs of abating. We feel the next generation of health care providers and administrators should be well informed on the many facets of nonclinical health care (regulation, delivery, socioeconomics) to guide health care systems and public servants toward better, more efficient care. We suspect that few possess even rudimentary knowledge in these fields. We constructed a 40-question Nonclinical Health Care Delivery aptitude test covering diverse subjects such as economics, finance, public health, governmental oversight, insurance, coding/billing, study design and interpretation, and more. The test was administered to over 150 medical students, residents, young physicians, nurse practitioners, nurses, physician assistants, administrators, and results tallied. There was, across the board, low aptitude in fundamental principles of nonclinical health care subjects. No single group performed particularly better than others. Almost all subjects showed profound gaps in knowledge. We found that aptitude for fundamental nonclinical health care subjects was profoundly lacking across all major groups of health care providers and administrators. We feel this indicates a need for a far more robust curriculum in health care delivery and socioeconomics. Failure to elevate the educational standards in this realm will jeopardize health care providers' seat at the table in changes in health care public policy.

    To estimate the prevalence of undernutrition among children with profound intellectual and multiple disabilities (PIMD) and to explore its influence on quality of life. Seventy-two children with PIMD (47 male; 25 female; age range 2 to 15 years 4 months; mean age 8.6, SD 3.6) underwent an anthropometric assessment, including body weight, triceps skinfold thickness, segmental measures and recumbent length. Undernutrition was determined using tricipital skinfold percentile and z-scores of weight-for-height and height-for-age. The quality of life of each child was evaluated using the QUALIN questionnaire adapted for profoundly disabled children. Twenty-five children (34.7%) were undernourished and seven (9.7%) were obese. Among undernourished children only eight (32 %) were receiving food supplements and two (8%) had a gastrostomy, of which one was still on a refeeding programme. On multivariate analysis, undernutrition was one of the independent predictors of lower quality of life. Undernutrition remains a matter of concern in children with PIMD. There is a need to better train professionals in systematically assessing the nutritional status of profoundly disabled children in order to start nutritional management when necessary. © 2013 John Wiley & Sons Ltd.

  19. Glutamatergic modulation of separation distress: profound emotional effects of excitatory amino acids in chicks.

    Science.gov (United States)

    Normansell, Larry; Panksepp, Jaak

    2011-10-01

    Pre-clinical models of brain affective circuits provide relevant evidence for understanding the brain systems that figure heavily in psychiatric disorders. Social isolation and the resulting separation distress contribute to the onset of depression. In this work, the effects of excitatory amino acids (EAA) on isolation-induced distress vocalization (DV) were assessed in young domestic chicks. Both glutamate and quisqualate (QA) produced dose-dependent reductions in DVs, while N-methyl-d-aspartate (NMDA) and kainate (KA) increased DVs. Such a differential pattern of responsiveness may indicate the presence of reciprocal or interacting EAA systems in the brain control of separation distress. Administration of either the NMDA receptor antagonist 2-amino-5-phosphonovalerate (APV) or the broad-spectrum antagonist gamma-d-glutamylglycine (DGG) greatly reduced DVs, as did the antagonist 2-amino-4-phosphonobutyrate (APB). APV did not attenuate the increase in vocalizations seen after NMDA or KA administration. DGG, however, was able to block the increase in calling produced by either of these agonists, suggesting a KA receptor mechanism. KA treatment inhibited the ability of other chicks, or auditory and somatosensory information, to suppress DVs. KA-treated animals exhibited a hyperemotional behavior pattern during which a variety of motivated behaviors were disrupted including reactions to novel objects, approaching the flock, and foraging. They could not sustain a coherent flock-like social cohesion, but exhibited strong fixed-action patterns of flight interspersed with hiding and crouching behaviors. The evident behavioral changes suggest that glutamatergic synapses directly influence sensory, motor and emotional processes in the brain and may be especially important in the integration of environmental stimuli with emotional central state processes of animals. Considering that unresolved social loss and grief have been deemed to be among the main precipitating causes

    Implicit mentalizing, a fast, unconscious and rigid way of processing other's mental states has recently received much interest in typical social cognitive development in early childhood and in adults with autism spectrum condition (ASC). This research suggests that already infants implicitly mentalize, and that adults with ASC have a sustained implicit mentalizing deficit. Yet, we have only sparse empirical evidence on implicit mentalizing beyond early childhood, and deviations thereof in children with ASC. Here, we administered an implicit mentalizing eye tracking task to assess the sensitivity to false beliefs to a group of 8-year-old children with and without ASC, matched for chronological age, verbal and non-verbal IQ. As previous research suggested that presenting outcomes of belief-based actions leads to fast learning from experience and false belief-congruent looking behavior in adults with ASC, we were also interested in whether already children with ASC learn from such information. Our results provide support for a persistent implicit mentalizing ability in neurotypical development beyond early childhood. Further, they confirmed an implicit mentalizing deficit in children with ASC, even when they are closely matched to controls for explicit mentalizing skills. In contrast to previous findings with adults, no experience-based modulation of anticipatory looking was observed. It seems that children with ASC have not yet developed compensatory general purpose learning mechanisms. The observed intact explicit, but impaired implicit mentalizing in ASC, and correlation patterns between mentalizing tasks and executive function tasks, are in line with theories on two dissociable mentalizing systems.

    The newly emerged Middle East respiratory syndrome coronavirus (MERS-CoV) infects human bronchial epithelial Calu-3 cells. Unlike severe acute respiratory syndrome (SARS)-CoV, which exclusively infects and releases through the apical route, this virus can do so through either side of polarized Calu-3 cells. Infection results in profound apoptosis within 24 h irrespective of its production of titers that are lower than those of SARS-CoV. Together, our results provide new insights into the dissemination and pathogenesis of MERS-CoV and may indicate that the virus differs markedly from SARS-CoV. PMID:23824802

    During the past decade, nursing education has been engaged in a curriculum revolution. Although this ongoing revolution has led to profound changes in nursing curricula, one area that requires further scrutiny is communication education. This article addresses the limitations of behavioral communication curricula and suggests a pedagogical process responsive to the complexity of human caring relationships and the intricacies of relational practice. The discussion includes a description of a nursing communication course developed according to the principles of transformational learning theory.

    Full Text Available There is limited evidence to underpin the assessment and management of pain in children with profound cognitive impairment and these children are vulnerable to poor pain assessment and management. Health professionals working with children with profound cognitive impairment from a single paediatric tertiary referral centre in England were interviewed to explore how they develop and acquire knowledge and skills to assess and manage pain in children with cognitive impairment. The interviews were transcribed and subjected to thematic analysis. Nineteen health professionals representing different professional groups and different levels of experience participated in the study. A metatheme “navigating uncertainty; deficits in knowledge and skills” and two core themes “framing as different and teasing things out” and “the settling and unsettling presence of parents” were identified. Uncertainty about aspects of assessing and managing the pain of children with cognitive impairment tended to erode professional confidence and many discussed deficits in their skill and knowledge set. Uncertainty was managed through engaging with other health professionals and the child’s parents. Most health professionals stated they would welcome more education and training although many felt that this input should be clinical and not classroom oriented.

    The influence of reperfusion after profound incomplete forebrain ischemia on blood-brain barrier (BBB) permeability to a small protein tracer was studied in male Sprague-Dawley rats. The mean cortical blood to brain transfer constant (Ki) for /sup 14/C-amino isobutyric acid (AIB) was significantly greater at 3 and 6 h of reperfusion, 2.5 times the mean values of controls (p less than 0.05) (2.5 microliter g-1 min-1 and 1.0 microliters g-1 min-1 respectively), but had returned to control values after reperfusion for 24 h. Analysis of distribution of Ki values showed that following 15 min and 30 min of profound ischemia, there was a significant increase in transfer of AIB across the blood-brain barrier (BBB) after recirculation for up to 6 h, though there was no evidence of protein extravasation as assessed by Evans Blue (EB) dye. After 24 h of reperfusion, the BBB to AIB was restored, and Ki values had returned to control values. It is concluded that following transient global ischemia, the BBB may recover rapidly.

    Cochlear implants (CIs) are used to provide sensations of sound to profoundly deaf patients. The performance of the CI is assessed mainly by the subjective reports of patients. The aim of this study was to look for objective cortical responses to the stimulation of the CI. Two postlingually and two prelingually deaf patients were investigated by positron emission tomography (PET) using {sup 15}O-labeled water (H{sub 2}{sup 15}O) to determine the regional cerebral blood flow (rCBF). Instead of quantifying rCBF in absolute terms, it was estimated by referring the regional tissue concentration of H{sub 2}{sup 15}O to the mean whole brain concentration. CI stimulation encoded from white noise and sequential words led to an increased rCBF in the primary and secondary (Wernicke) auditory cortex. Relative elevations of up to 33% were observed bilaterally, although they were higher contralateral to the CI. These results were obtained not only in the postlingually deaf patients but also in two patients who had never been able to hear. Thus, it could be demonstrated that PET measurements of cerebral H{sub 2}{sup 15}O distribution yield objective responses of the central auditory system during electrical stimulation by CIs in profoundly deaf patients.

    Early identification and intervention for prelingual bilateral severe to profound hearing loss is supposed to reduce the delay in language development. Many countries have implemented early detection and hearing intervention and conducted regional universal newborn hearing screening (UNHS). However, the benefits of UNHS in later childhood have not yet been confirmed, although language development at school age has a lifelong impact on children's future. Our Research on Sensory and Communicative Disorders project attempted to reveal the effects of UNHS and those of early intervention on the development of verbal communication in Japanese children. In this study, 319 children with prelingual bilateral severe to profound hearing loss, 4 to 10 years of age, were evaluated with the Test of Question-Answer Interaction Development used as an objective variable. Participation in UNHS and early intervention were used as explanatory variables. The adjusted odds ratio (AOR) was calculated after adjusting several confounding factors with use of logistic regression analysis. In addition, caregivers' answers were obtained by a questionnaire, and the process of diagnosis with and without UNHS was analyzed retrospectively. Early intervention was significantly associated with better language development (AOR, 3.23; p identification leads directly to early intervention.

    The ability to perform activities of daily living (ADL) as a component of participation is one of the factors that contribute to quality of life. The ability to perform ADL for persons experiencing severe/profound intellectual disability (ID) may be reduced due to their cognitive and physical capacities. However, until recently, the impact of the significantly prevalent visual impairments on the performance of activities of daily living has not yet been revealed within this group. The purpose of this prospective cross-sectional study was to investigate the impact of visual impairment on the performance of activities of daily living for persons with a severe/profound intellectual disability. The Barthel Index (BI) and Comfortable Walking Speed (CWS) were used to measure the ability of performing activities of daily living (ADL) in 240 persons with severe/profound ID and having Gross Motor Functioning Classification System (GMFCS) levels I, II or III; this included 120 persons with visual impairment. The impact of visual impairment on ADL was analyzed with linear regression. The results of the study demonstrated that visual impairment slightly affects the ability of performing activities of daily living (BI) for persons experiencing a severe/profound intellectual disability. GMFCS Levels II or III, profound ID level, and visual impairment each have the effect of lowering BI scores. GMFCS Levels II or III, and profound ID level each have the effect of increasing CWS scores, which indicates a lower walking speed. A main effect of visual impairment is present on CWS, but our results do show a substantive interaction effect between GMFCS level III and visual impairment on Comfortable Walking Speed in persons with a severe/profound intellectual disability. Visual impairment has a slight effect on ability to perform ADL in persons experiencing severe/profound ID. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Familial adenomatous polyposis (FAP is a hereditary autosomal dominant cancer syndrome, results from germ line mutation or deletion of the Adenomatous Polyposis Coli (APC gene on chromosome 5q21. Patients with FAP suffer from multiple polyps mainly at the colorectal region as well as other parts of the gastrointestinal tract, which has propensity to transform into carcinoma. FAP has also been well described in association with various syndromic extra-gastrointestinal manifestations. Less commonly, patients with FAP present with varying degrees of cognitive dysfunction and developmental delay, though the reason for the association is unclear. Herein, we report the case of a male patient born with an interstitial deletion of chromosome 5q, 46,XY, del(5 (q14q23, presenting with familial adenomatous polyposis (FAP, profound developmental delay, cognitive dysfunction, and multiple congenital anomalies including talipes equinovarus, agenesis of the corpus callosum, and dysmorphic facial features.

    2013-09-01

    Nine low-functioning children with profound expressive language impairment and autism were studied in terms of their responsiveness to a computer-based learning program designed to assess syntactic awareness. The children learned to touch words on a screen in the correct sequence in order to see a corresponding animation, such as 'monkey flies'. The game progressed in levels from 2 to 4 word sequences, contingent upon success at each stage. Although performance was highly variable across participants, a detailed review of their learning profiles suggested that no child lacked syntactic awareness and that elementary syntactic control in a non-speech domain was superior to that manifest in their spoken language. The reasons for production failures at the level of speech in children with autism are discussed.

    2014-05-01

    Utilizing grounded theory qualitative research methods, a model was developed for describing parental adaptation after voluntary placement of a child with severe or profound developmental disabilities in out-of-home care. Interviews of parents from 20 families were analyzed. Parents' cognitive appraisals of placement outcomes were classified as either inducing emotional stress (i.e., guilt, sadness, fear and worry, anger and frustration, and uncertainty) or relief. Parental appraisals of responses to placement by children, extended family, and friends were identified as factors affecting the parents' adaptation to placement. The primary coping methods used by parents to decrease emotional stress and increase relief consisted of reappraisals regarding the necessity of placement, involvement in the child's life, psychotherapy, and the passage of time.

    2016-08-01

    Profound and multiple learning disabilities (PMLD) are a complex range of disabilities that affect the general health and well-being of the individual and their capacity to interact and learn. We developed a new methodology to capture the non-symbolic signalling behaviours of children with PMLD within the context of a face-to-face interaction with a caregiver to provide analysis at a micro-level of descriptive detail incorporating the use of the ELAN digital video software. The signalling behaviours of participants in a natural, everyday interaction can be better understood with the use of this innovation in methodology, which is predicated on the ecology of communication. Recognition of the developmental ability of the participants is an integral factor within that ecology. The method presented establishes an advanced account of the modalities through which a child affected by PMLD is able to communicate.

    There is little data on the collaboration between parents and professionals in the support of persons with profound intellectual and multiple disabilities. Since communication is essential to collaboration, this study analysed the frequency, means, and personal experiences of communication between parents and professionals. A multiple case study ( n = 4) was conducted. Observations were logged for every contact between professionals and parents during 12 months. The mean number of contacts a month ranged from 1.9 to 16.7 across the cases. Most of the contacts were with the child's direct support persons (85.2%) and exchanging information (35.5%) was the most common function. Issues concerning health (28.4%) were the most common subjects discussed. The majority of the mothers' experiences were positive. Direct support persons play a crucial role; they need to be aware of this role and to be trained to fulfill their role to acknowledge parents as partners.

    Assessment of the clinical effectiveness of bilateral cochlear implantation compared with unilateral cochlear implantation or bimodal stimulation, in adults with severe-to-profound hearing loss. In 2007, the National Institute for Health and Clinical Excellence (NICE) in the U.K. conducted a systematic review on cochlear implantation. This study forms an update of the adult part of the NICE review. The electronic databases MEDLINE and Embase were searched for English language studies published between October 2006 and March 2011. Studies were included that compared bilateral cochlear implantation with unilateral cochlear implantation and/or with bimodal stimulation, in adults with severe-to-profound sensorineural hearing loss. Speech perception in quiet and in noise, sound localization and lateralization, speech production, health-related quality of life, and functional outcomes were analyzed. Data extraction forms were used to describe study characteristics and the level of evidence. The effect size was calculated to compare different outcome measures. Pooling of data was not possible because of the heterogeneity of the studies. As in the NICE review, the level of evidence of the included studies was low, although some of the additional studies showed less risk of bias. All studies showed a significant bilateral benefit in localization over unilateral cochlear implantation. Bilateral cochlear implants were beneficial for speech perception in noise under certain conditions and several self-reported measures. Most speech perception in quiet outcomes did not show a bilateral benefit. The current review provides additional evidence in favor of bilateral cochlear implantation, even in complex listening situations.

    Approximately one-third of patients with epilepsy continue to experience seizures despite adequate therapy with antiepileptic drugs. Drug-resistant epilepsy is even more frequent in subjects with intellectual disability. As a result, several non-pharmacological interventions have been proposed to improve quality of life in patients with intellectual disability and drug-resistant epilepsy. A number of studies have demonstrated that music can be effective at reducing seizures and epileptiform discharges. In particular, Mozart's sonata for two pianos in D major, K448, has been shown to decrease interictal EEG discharges and recurrence of clinical seizures in patients with intellectual disability and drug-resistant epilepsy as well. The aim of this study is to investigate the influence of Mozart's music on seizure frequency in institutionalized epileptic subjects with profound/severe intellectual disability. Twelve patients (10 males and 2 females) with a mean age of 21.6 years were randomly assigned to two groups in a cross-over design; they listened to Mozart K448 once a day for six months. A statistically significant difference was observed between the listening period and both baseline and control periods. During the music period, none of the patients worsened in seizure frequency; one patient was seizure-free, five had a greater than 50% reduction in seizure frequency and the remaining showed minimal (N=2) or no difference (N=4). The average seizure reduction compared to the baseline was 20.5%. Our results are discussed in relation to data in the literature considering differences in protocol investigation. Music may be considered a useful approach as add-on therapy in some subjects with profound intellectual disability and drug-resistant epilepsy and can provide a new option for clinicians to consider, but further large sample, multicenter studies are needed to better understand the characteristics of responders and non-responders to this type of non

    Autosomal recessive deafness is the most common form of human hereditary hearing loss. Two percent of the 2,185 residents of Bengkala, Bali, Indonesia have profound congenital neurosensory nonsyndromal hereditary deafness due to a fully penetrant autosomal recessive mutation (NARD1). Families, identified through children with profound congenital deafness having hearing parents, give the expected 25% deaf progeny when corrected for ascertainment bias. Congenitally deaf individuals from Bengkala show no response to pure tone audiological examination. Obligate heterozygotes for autosomal recessive deafness in Bengkala have normal or borderline normal hearing. A chromosomal location for NARD1 was assigned directly using a linkage strategy that combines allele-frequency dependent homozygosity mapping (AHM) followed by an analysis of historical recombinants to position NARD1 relative to flanking markers. Thirteen deaf Bengkala villagers of hearing parents were typed initially for 148 STRPs distributed across the human genome and a cluster of tightly linked 17p markers with a significantly higher number of homozygotes than expected under Hardy-Weinberg and linkage equilibrium were identified. NARD1 maps closest to STRPs for D17S261 (Mfd41) and D17S805 (AFM234ta1) that are 3.2 cM apart. Recombinant genotypes for the flanking markers, D17S122 (VAW409) and D17S783 (AFM026vh7), in individuals homozygous for NARD1 place NARD1 in a 5.3 cM interval of the pericentromeric region of chromosome 17 on a refined 17p-17q12 genetic map.

  7. HIV-1 coinfection profoundly alters intrahepatic chemokine but not inflammatory cytokine profiles in HCV-infected subjects.

    Full Text Available The pathogenesis of accelerated liver damage in subjects coinfected with hepatitis C virus (HCV and human immunodeficiency virus type 1 (HIV-1 remains largely unknown. Recent studies suggest that ongoing chronic liver inflammation is responsible for the liver injury in HCV-infected patients. We aimed to determine whether HIV-1 coinfection altered intrahepatic inflammatory profiles in HCV infection, thereby hastening liver damage. We used a real-time RT-PCR-based array to comparatively analyze intrahepatic inflammation gene profiles in liver biopsy specimens from HCV-infected (n = 16, HCV/HIV-1-coinfected (n = 8 and uninfected (n = 8 individuals. We then used human hepatocytes to study the molecular mechanisms underlying alternations of the inflammatory profiles. Compared with uninfected individuals, HCV infection and HCV/HIV-1 coinfection markedly altered expression of 59.5% and 50.0% of 84 inflammation-related genes tested, respectively. Among these genes affected, HCV infection up-regulated the expression of 24 genes and down-regulated the expression of 26 genes, whereas HCV/HIV-1 coinfection up-regulated the expression of 21 genes and down-regulated the expression of 21 genes. Compared with HCV infection, HCV/HIV-1 coinfection did not dramatically affect intrahepatic gene expression profiles of cytokines and their receptors, but profoundly altered expression of several chemokine genes including up-regulation of the CXCR3-associated chemokines. Human hepatocytes produced these chemokines in response to virus-related microbial translocation, viral protein stimulation, and antiviral immune responses.HIV-1 coinfection profoundly alters intrahepatic chemokine but not cytokine profiles in HCV-infected subjects. The altered chemokines may orchestrate the tissue-specific and cell-selective trafficking of immune cells and autoimmunity to accelerate liver disease in HCV/HIV-1 coinfection.

    The prevalence of Helicobacter pylori infection is inversely associated with socioeconomic conditions in childhood. In Estonia, a high prevalence of H. pylori infection has been observed among children born in 1987 and earlier. Since 1991, after the dissolution of the USSR, profound social and economic changes have taken place in the country. The aim of the study was to evaluate changes in the seroprevalence of H. pylori infection among children in the period 1991-2002. The hospital-based study population consisted of two groups of children enrolled in 1991 (n = 425) and 2002 (n = 296) according to the same inclusion criteria. The immunoglobulin G antibodies to the cell surface proteins of H. pylori were determined by enzyme-linked immunosorbent assay, and the sera with the borderline results were analyzed by immunoblot analysis. Multiple regression analysis was used to determine the associations between H. pylori seropositivity and different variables such as demographic characteristics, diagnoses and year of enrollment. The only two variables linked independently to H. pylori serostatus were age and year of enrollment: the adjusted odds of being H. pylori seropositive were 1.92 [95% confidence interval (CI) 1.33-2.76] times higher for the children enrolled in 1991 compared with the children enrolled in 2002. The age-standardized seroprevalence rate was 42.2% (95% CI 37.4-47.0%) for the group of 1991 and 28.1% (95% CI 23.1-33.6%) for the group of 2002. The prevalence of H. pylori infection among children has significantly decreased during the 11-year period of profound socioeconomic changes in Estonia.

    A systematic review of the literature and meta-analysis was conducted to assess the nature and quality of the evidence for the use of hearing instruments in adults with a unilateral severe to profound sensorineural hearing loss. The PubMed, EMBASE, MEDLINE, Cochrane, CINAHL, and DARE databases were searched with no restrictions on language. The search included articles from the start of each database until February 11, 2015. Studies were included that (a) assessed the impact of any form of hearing instrument, including devices that reroute signals between the ears or restore aspects of hearing to a deaf ear, in adults with a sensorineural severe to profound loss in one ear and normal or near-normal hearing in the other ear; (b) compared different devices or compared a device with placebo or the unaided condition; (c) measured outcomes in terms of speech perception, spatial listening, or quality of life; (d) were prospective controlled or observational studies. Studies that met prospectively defined criteria were subjected to random effects meta-analyses. Twenty-seven studies reported in 30 articles were included. The evidence was graded as low-to-moderate quality having been obtained primarily from observational before-after comparisons. The meta-analysis identified statistically significant benefits to speech perception in noise for devices that rerouted the speech signals of interest from the worse ear to the better ear using either air or bone conduction (mean benefit, 2.5 dB). However, these devices also degraded speech understanding significantly and to a similar extent (mean deficit, 3.1 dB) when noise was rerouted to the better ear. Data on the effects of cochlear implantation on speech perception could not be pooled as the prospectively defined criteria for meta-analysis were not met. Inconsistency in the assessment of outcomes relating to sound localization also precluded the synthesis of evidence across studies. Evidence for the relative efficacy of

    (Z)-3,5,4′-Trimethoxystilbene (Z-TMS) is a resveratrol analog with increased antiproliferative activity towards a number of cancer cell lines compared to resveratrol, which has been shown to inhibit tubulin polymerization in vitro. The purpose of this study was to investigate if Z-TMS still shows potential for the prevention of metabolic diseases as known for resveratrol. Cell growth inhibition was determined with IC{sub 50} values for Z-TMS between 0.115 μM and 0.473 μM (resveratrol: 110.7 μM to 190.2 μM). Flow cytometric analysis revealed a G{sub 2}/M arrest after Z-TMS treatment, whereas resveratrol caused S phase arrest. Furthermore, Z-TMS was shown to impair microtubule polymerization. Beneficial effects on lipid accumulation were observed for resveratrol, but not for Z-TMS in an in vitro steatosis model. (E)-Resveratrol was confirmed to elevate cAMP levels, and knockdown of AMPK attenuated the antiproliferative activity, while Z-TMS did not show significant effects in these experiments. SIRT1 and AMPK activities were further measured indirectly via induction of the target gene small heterodimer partner (SHP). Thereby, (E)-resveratrol, but not Z-TMS, showed potent induction of SHP mRNA levels in an AMPK- and SIRT1-dependent manner, as confirmed by knockdown experiments. We provide evidence that Z-TMS does not show beneficial metabolic effects, probably due to loss of activity towards resveratrol target genes. Moreover, our data support previous findings that Z-TMS acts as an inhibitor of tubulin polymerization. These findings confirm that the methylation of resveratrol leads to profound changes in the mode of action, which should be taken into consideration when conducting lead structure optimization approaches. - Highlights: • Methylation of resveratrol leads to profound changes in biologic activity. • Z-TMS does not prevent hepatic steatosis, but inhibits tubulin polymerization. • Resveratrol analog Z-TMS does not influence known targets like

    Multi-sensory storytelling (MSST) was developed to include persons with profound intellectual and multiple disabilities in storytelling culture. In order to increase the listeners' attention, MSST stories are individualised and use multiple sensory stimuli to support the verbal text. In order to determine the value of MSST, this study compared listeners' attention under two conditions: (1) being read MSST books and (2) being read regular stories. A non-randomised control study was executed in which the intervention group read MSST books (n = 45) and a comparison group (n = 31) read regular books. Books were read 10 times during a 5-week period. The 1st, 5th and 10th storytelling sessions were recorded on video in both groups, and the percentage of attention directed to the book and/or stimuli and to the storyteller was scored by a trained and independent rater. Two repeated measure analyses (with the storytelling condition as a between-subject factor and the three measurements as factor) were performed to determine the difference between the groups in terms of attention directed to the book/stimuli (first analysis) and storyteller (second analysis). A further analysis established whether the level of attention changed between the reading sessions and whether there was an interaction effect between the repetition of the book and the storytelling condition. The attention directed to the book and/or the stimuli was significantly higher in the MSST group than in the comparison group. No significant difference between the two groups was found in the attention directed to the storyteller. For MSST stories, most attention was observed during the fifth reading session, while for regular stories, the fifth session gained least attentiveness from the listener. The persons with profound intellectual and multiple disabilities paid more attention to the book and/or stimuli in the MSST condition compared with the regular story telling group.

    The United Nations Convention on the Rights of Persons with Disabilities (UNCRPD) promotes the use of supported decision making in lieu of substitute decision making. To date, there has been a lack of focus on supported decision making for people with severe or profound intellectual disability, including for end of life decisions. Five people with severe or profound intellectual disability's experiences of supported decision making were examined. This article is particularly focused on one participant's experiences at the end of his life. All five case studies identified that supporters were most effective in providing decision-making support for participants when they were relationally close to the person and had knowledge of the person's life story, particularly in relation to events that demonstrated preference. Findings from this study provide new understandings of supported decision making for people with severe or profound intellectual disability and have particular relevance for supporting decision making at the end of life. © 2017 John Wiley & Sons Ltd.

    Chronic left ventricular failure causes pulmonary congestion with increased lung weight and type 2 pulmonary hypertension. Understanding the molecular mechanisms for type 2 pulmonary hypertension and the development of novel treatments for this condition requires a robust experimental animal model and a good understanding of the nature of the resultant pulmonary remodeling. Here we demonstrate that chronic transverse aortic constriction causes massive pulmonary fibrosis and remodeling, as well as type 2 pulmonary hypertension, in mice. Thus, aortic constriction-induced left ventricular dysfunction and increased left ventricular end-diastolic pressure are associated with a ≤5.3-fold increase in lung wet weight and dry weight, pulmonary hypertension, and right ventricular hypertrophy. Interestingly, the aortic constriction-induced increase in lung weight was not associated with pulmonary edema but resulted from profound pulmonary remodeling with a dramatic increase in the percentage of fully muscularized lung vessels, marked vascular and lung fibrosis, myofibroblast proliferation, and leukocyte infiltration. The aortic constriction-induced left ventricular dysfunction was also associated with right ventricular hypertrophy, increased right ventricular end-diastolic pressure, and right atrial hypertrophy. The massive lung fibrosis, leukocyte infiltration, and pulmonary hypertension in mice after transverse aortic constriction clearly indicate that congestive heart failure also causes severe lung disease. The lung fibrosis and leukocyte infiltration may be important mechanisms in the poor clinical outcome in patients with end-stage heart failure. Thus, the effective treatment of left ventricular failure may require additional efforts to reduce lung fibrosis and the inflammatory response.

    We evaluated the cognitive development of 48 profoundly deaf children from hearing families (born 1994-2002, mean age M = 8.0 years at time of test, none of whom had received early auditory-verbal therapy) as a function of family socioeconomic status and number of siblings. Overall, the deaf children matched a younger group of 47 hearing controls (M = 4.6 years) on verbal ability, theory of mind, and cognitive inhibition. Partial correlations (controlling for age) revealed positive relations in the hearing group between maternal education and inhibition, between number of younger siblings and references to emotions, and between number of close-in-age siblings and references to desires and false beliefs. In the deaf group, there were positive relations between household income and memory span, between maternal education and references to false beliefs, and between number of younger siblings and nonverbal ability. In contrast, deaf children with a greater number of older siblings aged ≤12 years showed inferior memory span, inhibition, belief understanding, picture-sequencing accuracy, and mental-state language, suggesting that they failed to compete successfully with older siblings for their parents' attention and material resources. We consider the implications of the findings for understanding birth-order effects on deaf and language-impaired children.

    Self-assembly of small biomolecules is a prevalent phenomenon that is increasingly being recognised to hold the key to building complex structures from simple monomeric units. Small peptides, in particular ultrashort peptides containing up to seven amino acids, for which our laboratory has found many biomedical applications, exhibit immense potential in this regard. For next-generation applications, more intricate control is required over the self-assembly processes. We seek to find out how subtle moiety variation of peptides can affect self-assembly and nanostructure formation. To this end, we have selected a library of 54 tripeptides, derived from systematic moiety variations from seven tripeptides. Our study reveals that subtle structural changes in the tripeptides can exert profound effects on self-assembly, nanostructure formation, hydrogelation, and even phase transition of peptide nanostructures. By comparing the X-ray crystal structures of two tripeptides, acetylated leucine-leucine-glutamic acid (Ac-LLE) and acetylated tyrosine-leucine-aspartic acid (Ac-YLD), we obtained valuable insights into the structural factors that can influence the formation of supramolecular peptide structures. We believe that our results have major implications on the understanding of the factors that affect peptide self-assembly. In addition, our findings can potentially assist current computational efforts to predict and design self-assembling peptide systems for diverse biomedical applications.

  16. Communication strategies and intensive interaction therapy meet the theology of the body: bioethics in dialogue with people with profound disabilities.

    Academic bioethics does not appear to be interested in communication and its ethical concerns unless communication is to do with issues such as capacity, consent, truth telling and confidentiality. In contrast practitioners are interested in actually communicating with their patients and they are often particularly perplexed when it comes to people with profound disabilities where communication appears disrupted. Although some new and not so new communication strategies, and especially intensive interaction, are available, little has been written on either the ethical concerns these may present or the deeper concepts that underpin them. This article explores the practical applications of some of these communication strategies. By engaging these strategies with theology, and specifically Pope John Paul's Theology of the Body, this article identifies and addresses some significant ethical issues that may arise, notably the risk of dualism and of objectifying the human person. Moreover it provides communication strategies with a rationale that goes beyond practicalities to one based on respect for human dignity, justice and solidarity.

    Full Text Available The purpose of this paper is to provide a preliminary, qualitative review of an approach to training centre-based carers in supporting basic communication development and providing communication opportunities for the children with severe and profound disabilities in their care. In South Africa, these children are often the most neglected in terms of planning and providing appropriate interventions. For those with severe communication disabilities, an additional lack is in the area of the basic human right to meaningful interactions and communication. Sustainable strategies to provide opportunities for basic communication development of these children are urgently sought. Several effective international and local parent training programmes have been developed, but the urgent need remains to train centre-based carers who are taking care of groups of diversely disabled children in severely under-resourced settings. Non-profit organisations (NPOs have been exploring practical centre-based approaches to skills sharing in physical rehabilitation, activities for daily living, feeding and support for basic communication development. As a freelance speech therapist contracted by four NPOs to implement hands-on training in basic communication for centre-based carers of non-verbal children, the author describes a training approach that evolved over three years, in collaboration with the carers and centre managements. Implications for training (for speech therapists and for community-based rehabilitation workers and for further research are identified.

    The lamin B receptor (LBR) is a highly unusual inner nuclear membrane protein with multiple functions. Reduced levels are associated with decreased neutrophil lobularity, whereas complete absence of LBR results in severe skeletal dysplasia and in utero/perinatal lethality. We describe a mouse pedigree, Lym3, with normal bone marrow and thymic development but profound and progressive lymphopenia particularly within the T cell compartment. This defect arises from a point mutation within the Lbr gene with only trace mutant protein detectable in homozygotes, albeit sufficient for normal development. Reduced T cell homeostatic proliferative potential and life span in vivo were found to contribute to lymphopenia. To investigate the role of LBR in gene silencing in hematopoietic cells, we examined gene expression in wild-type and mutant lymph node CD8 T cells and bone marrow neutrophils. Although LBR deficiency had a very mild impact on gene expression overall, for common genes differentially expressed in both LBR-deficient CD8 T cells and neutrophils, gene upregulation prevailed, supporting a role for LBR in their suppression. In summary, this study demonstrates that LBR deficiency affects not only nuclear architecture but also proliferation, cell viability, and gene expression of hematopoietic cells.

    End-of-life decisions (EoLD) often concern children with profound intellectual and multiple disabilities (PIMD). Yet, little is known about how parents and physicians discuss and make these decisions. The objective of this research was to investigate the experiences of the parents and the involved physician during the end-of-life decision-making (EoLDM) process for children with PIMD. In a retrospective, qualitative study, we conducted semi-structured interviews with the physicians and parents of 14 children with PIMD for whom an EoLD was made within the past two years. A long-lasting relationship appeared to facilitate the EoLDM process, although previous negative healthcare encounters could also lead to distrust. Parents and physicians encountered disagreements during the EoLDM process, but these disagreements could also improve the decision-making process. Most parents, as well as most physicians, considered the parents to be the experts on their child. In making an EoLD, both parents and physicians preferred a shared decision-making approach, although they differed in what they actually meant by this concept. The EoLDM process for children with PIMD can be improved if physicians are more aware of the specific situation and of the roles and expectations of the parents of children with PIMD.

    Full Text Available Abstract Background Global gene expression profiles of bovine kidney epithelial cells regulated by sodium butyrate were investigated with high-density oligonucleotide microarrays. The bovine microarray with 86,191 distinct 60mer oligonucleotides, each with 4 replicates, was designed and produced with Maskless Array Synthesizer technology. These oligonucleotides represent approximately 45,383 unique cattle sequences. Results 450 genes significantly regulated by butyrate with a median False Discovery Rate (FDR = 0 % were identified. The majority of these genes were repressed by butyrate and associated with cell cycle control. The expression levels of 30 selected genes identified by the microarray were confirmed using real-time PCR. The results from real-time PCR positively correlated (R = 0.867 with the results from the microarray. Conclusion This study presented the genes related to multiple signal pathways such as cell cycle control and apoptosis. The profound changes in gene expression elucidate the molecular basis for the pleiotropic effects of butyrate on biological processes. These findings enable better recognition of the full range of beneficial roles butyrate may play during cattle energy metabolism, cell growth and proliferation, and possibly in fighting gastrointestinal pathogens.

    The interactions experienced by adults with profound intellectual and multiple disabilities (PIMD) with their disability support workers (DSWs) may have a large impact on life quality. However, defining good-quality interaction has presented challenges for this group. It has been suggested that in typically developing infant-mother dyads, the presence of affect attunement may be an indicator of quality. Affect attunement refers to the recasting of one person's affect by another with emphasis. The presence and nature of affect attunement in interactions between 21 pairs of adults with PIMD and their DSWs were explored in this study. Natural interactions were videorecorded for 21 pairs of adults with PIMD and their DSWs. The recordings were analysed for the presence and nature of affect attunement incidents, and analysed using descriptive statistics. Affect attunement incidents were observed in 16 of the pairs. The DSW's attunement behaviour was in response to subtle, short duration behaviours of participants with PIMD. These brief moments of connection may be a basis of good-quality interaction. © 2013 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

    While optimally activities are provided at those moments when the individual with profound intellectual and multiple disabilities (PIMD) is 'focused on the environment' or 'alert', detailed information about the impact that the design and timing of the activity has on alertness is lacking. Therefore, the aim of the present study is to shed light on the sequential relationship between different stimuli and alertness levels in individuals with PIMD. Video observations were conducted for 24 participants during one-on-one interactions with a direct support person in multisensory environments. Time-window sequential analyses were conducted for the 120 s following four different stimuli. For the different stimuli, different patterns in terms of alertness became apparent. Following visual stimuli, the alertness levels of the individuals with PIMD changed in waves of about 20 s from 'active alert' to 'passive alert'. While auditory and tactile stimuli led to 'alert' reactions shortly after the stimulation, alertness levels decreased between seconds 20 and 120. Reactions to vestibular stimuli were only visible after 60 s; these were 'active alert' or 'withdrawn'. The results of the present study show that individuals with PIMD show their reactions to stimuli only slightly, so that 'waves' might reflect the optimal alertness pattern for learning and development. Consequently, it is especially important that direct support persons follow and stimulate these individual 'waves' in the activities they provide to their clients. © 2012 John Wiley & Sons Ltd.

    Full Text Available Although the immune status of chronic lymphocytic leukemia (CLL patients is mostly characterized by immunosuppression, there is an accumulation of in vivo (graft-versus-leukemia effect and in vitro (spontaneous remissions after infections data that indicates that CLL might be effectively targeted by T-cell based immunotherapy. Recently, we characterized receptor for hyaluronic acid mediated motility (RHAMM as a preferential target for immunotherapy of CLL. We also completed a RHAMM-derived peptide vaccination phase I/II clinical trial in CLL. Here, we present a detailed immunological analysis of six CLL patients vaccinated with HLA-A2 restricted RHAMM-derived epitope R3 (ILSLELMKL. Beside effective induction of R3-specific cytotoxic T-cells, peptide vaccination caused profound changes in different T-cell subsets as well as cytokines. We present longitudinal analyses of Th17, CD8+CD103+, CD8+CD137+ and IL-17 producing CD8+ T cells (CD8+IL- -17+ as well as important cytokines involved in regulation of immune response such as TGF-β, IL-10, IL-2 and TNF throughout the peptide vaccination period.

    This paper was to provide an overview of research studies aimed at increasing indices of happiness of persons with severe/profound intellectual and multiple disabilities. Computerized and manual searches were carried out to identify the studies published from 1990 to 2004 (i.e., the period during which the issues of quality fo life and happiness in people with disabilities have become more prominent). Twenty-four research studies were identified. They involved the use of six different procedures, that is, structured stimulation sessions, microswitch-based simulation sessions, leisure activities and favourite work tasks or conditions, positive environment or positive behaviour support programmes and mindful caregiving, favourite stimulation automatically delivered on exercise engagement, and snoezelen. Data tended to be positive with increases in the participants' indices of happiness, but some failures also occurred. The outcomes were discussed in relation to (a) methodological issues, such as designs of the studies, length of the intervention, and number of participants, and (b) personal and practical implications of the procedures. Some suggestions for future research (particularly focused on extending evidence and overcoming present methodological weakness) were also examined.

    2017-01-01

    Full Text Available Children with profound cognitive impairment (PCI are a heterogenous group who often experience frequent and persistent pain. Those people closest to the child are key to assessing their pain. This mixed method study aimed to explore how parents acquire knowledge and skills in assessing and managing their child’s pain. Eight mothers completed a weekly pain diary and were interviewed at weeks 1 and 8. Qualitative data were analysed using thematic analysis and the quantitative data using descriptive statistics. Mothers talked of learning through a system of trial and error (“learning to get on with it”; this was accomplished through “learning to know without a rule book or guide”; “learning to be a convincing advocate”; and “learning to endure and to get things right.” Experiential and reflective learning was evident in the way the mothers developed a “sense of knowing” their child’s pain. They drew on embodied knowledge of how their child usually expressed and responded to pain to help make pain-related decisions. Health professionals need to support mothers/parents to develop their knowledge and skills and to gain confidence in pain assessment and they should recognise and act on the mothers’ concerns.

    T cells are key players in the chronic intestinal inflammation that characterises Crohn's disease. Here we aim to map the intestinal T-cell receptor [TCR] repertoire in patients with Crohn's disease, using next-generation sequencing technology to examine the clonality of the T-cell compartment in relation to mucosal inflammation and response to therapy. Biopsies were taken from endoscopically inflamed and uninflamed ileum and colon of 19 patients with Crohn's disease. From this cohort, additional biopsies were taken after 8 weeks of remission induction therapy from eight responders and eight non-responders. Control biopsies from 11 patients without inflammatory bowel disease [IBD] were included. The TCRβ repertoire was analysed by next-generation sequencing of biopsy RNA. Both in Crohn's disease patients and in non-IBD controls, a broad intestinal T-cell repertoire was found, with a considerable part consisting of expanded clones. Clones in Crohn's disease were more expanded [p = 0.008], with the largest clones representing up to as much as 58% of the total repertoire. There was a substantial overlap of the repertoire between inflamed and uninflamed tissue and between ileum and colon. Following therapy, responders showed larger changes in the T-cell repertoire than non-responders, although a considerable part of the repertoire remained unchanged in both groups. The intestinal T-cell repertoire distribution in Crohn's disease is different from that in the normal gut, containing profoundly expanded T-cell clones that take up a large part of the repertoire. The T-cell repertoire is fairly stable regardless of endoscopic mucosal inflammation or response to therapy.

    The impact of metabolic engineering on nontarget pathways and outcomes of metabolic engineering from different genomes are poorly understood questions. Therefore, squalene biosynthesis genes FARNESYL DIPHOSPHATE SYNTHASE (FPS) and SQUALENE SYNTHASE (SQS) were engineered via the Nicotiana tabacum chloroplast (C), nuclear (N) or both (CN) genomes to promote squalene biosynthesis. SQS levels were ~4300-fold higher in C and CN lines than in N, but all accumulated ~150-fold higher squalene due to substrate or storage limitations. Abnormal leaf and flower phenotypes, including lower pollen production and reduced fertility, were observed regardless of the compartment or level of transgene expression. Substantial changes in metabolomes of all lines were observed: levels of 65-120 unrelated metabolites, including the toxic alkaloid nicotine, changed by as much as 32-fold. Profound effects of transgenesis on nontarget gene expression included changes in the abundance of 19 076 transcripts by up to 2000-fold in CN; 7784 transcripts by up to 1400-fold in N; and 5224 transcripts by as much as 2200-fold in C. Transporter-related transcripts were induced, and cell cycle-associated transcripts were disproportionally repressed in all three lines. Transcriptome changes were validated by qRT-PCR. The mechanism underlying these large changes likely involves metabolite-mediated anterograde and/or retrograde signalling irrespective of the level of transgene expression or end product, due to imbalance of metabolic pools, offering new insight into both anticipated and unanticipated consequences of metabolic engineering. © 2016 The Authors.

    The present study investigates how auditory stimulation from cochlear implants (CI) is associated with the development of Theory of Mind (ToM) in severely and profoundly hearing impaired children with hearing parents. Previous research has shown that deaf children of hearing parents have a delayed ToM development. This is, however, not always the case with deaf children of deaf parents, who presumably are immersed in a more vivid signing environment. Sixteen children with CI (4.25 to 9.5 years of age) were tested on measures of cognitive and emotional ToM, language and cognition. Eight of the children received their first implant relatively early (before 27 months) and half of them late (after 27 months). The two groups did not differ in age, gender, language or cognition at entry of the study. ToM tests included the unexpected location task and a newly developed Swedish social-emotional ToM test. The tests aimed to test both cognitive and emotional ToM. A comparison group of typically developing hearing age matched children was also added (n=18). Compared to the comparison group, the early CI-group did not differ in emotional ToM. The late CI-group differed significantly from the comparison group on both the cognitive and emotional ToM tests. The results revealed that children with early cochlear implants solved ToM problems to a significantly higher degree than children with late implants, although the groups did not differ on language or cognitive measures at baseline. The outcome suggests that early cochlear implantation for deaf children in hearing families, in conjunction with early social and communicative stimulation in a language that is native to the parents, can provide a foundation for a more normalized ToM development.

    The low concentration of O2 in the thin air at high altitude is undoubtedly the reason for the remarkable modifications in the structure and function of the heart, lung, and blood of humans permanently living under these conditions. The effect of natural hypoxia on the energy metabolism of the cell is however not well understood. Here we study the proces of ATP synthesis in the heart of guinea pigs native to high altitude (4500 m) as compared with those native to sea level. The following are the novel findings of this study. (1) The rates and extents of ATP synthesis in the presence of low concentrations of ADP (<30 microM) are significantly higher at high altitude than at sea level. (2) The Hill coefficient, i.e. the degree of cooperativity between the three catalytic sites of the ATP synthase, is lower at high altitude (n = 1.36) than at sea level (n = 1.94). (3) Both, the affinity for ADP and the fractional occupancy of the catalytic sites by ATP, are higher at high altitude than at sea level but the P50, i.e. the concentration of ADP at which 50% of the catalytic sites are filled with ADP and/or ATP, is the same (approximately 74.7 microM). (4) In the physiological range of ADP concentrations, the phosphorylation potential deltaGp is significantly higher at high altitude than at sea level. It is concluded that the molecular mechanism of energy transduction is profoundly modified at high altitude in order to readily and efficiently generate ATP in the presence of low concentrations of O2 and ADP.

    A study has shown that staff do not generally perceive challenging behaviour in people with profound intellectual and multiple disabilities (PIMD) as being of serious consequence. In this study we aimed to gain a better understanding of the causal explanations that direct care and support staff give for challenging behaviour in this group. The purpose of this study was twofold: (1) to determine the way staff attribute challenging behaviour in children and adults with PIMD; and (2) to analyse whether more experienced staff attribute challenging behaviour in children and adults with PIMD differently than less experienced staff. In total, 195 direct support staff and an equal number of children and adults with PIMD participated in the study. Direct support staff filled out the Challenging behaviour Attribution Scale (five causal explanatory models of challenging behaviour) to explain challenging behaviour in one individual that they supported. The results show that direct support staff as a whole report the biomedical model as the most plausible explanation for challenging behaviour in children and adults with PIMD. However, in the present study the mean scores on all models are low. This might indicate that a large number of staff found none of the models particularly useful as possible explanations of challenging behaviour in people with PIMD. This could mean that staff have difficulties stating the cause of challenging behaviour in this group. Another possible explanation could be that there is little scientific knowledge about causing and maintaining factors of challenging behaviour in people with PIMD. It could also mean that staff have additional explanations for challenging behaviour in this target group that are not mentioned in the instrument used. Future research should address these issues. No differences were found between more experienced and less experienced direct support staff. Copyright © 2015 Elsevier Ltd. All rights reserved.

  11. Specific needs of families of young adults with profound intellectual disability during and after transition to adulthood: What are we missing?

    2017-07-01

    At the age of 21, the trajectory of services offered to youth with profound intellectual disability (ID) change significantly since access to specialised services is more limited. Despite the desire of parents to avoid any impact on their child, several factors can influence the course of this transition. However, there is little research on facilitators and obstacles to the transition to adulthood, and impacts on people with a profound ID. It is therefore difficult to provide solutions that meet their specific needs. The study aimed to document the needs of parents and young adults with profound ID during and after the transition to adulthood by exploring their transitioning experience and factors that influenced it. Using a descriptive qualitative design, two individual semi-structured interviews were conducted with fourteen (14) parents of young adults aged between 18 and 26 with a profound ID. At this point, many material, informative, cognitive and emotional needs of young adults and their parents are not met. Obstacles, mainly organisational, persist and result in a particularly difficult transition to adulthood experience. By knowing the specific needs of these families, it is possible to develop and implement solutions tailored to their reality. WHAT THE PAPERS ADDS?: The transition to adulthood is a critical period for families with young adults with an intellectual disability (ID), a reality observed internationally. Current literature on all levels of ID suggests some barriers to transition that lead to negative impacts on both parents and young adults with ID. However, presently, very little research exists on the reality of families of young adults with profound ID and factors influencing transition to adult life. Most of studies target people with mild to moderate ID. Considering the significant disabilities of people with profound ID, it is possible to imagine that their experience of transition will be even more difficult and they will present

    We investigated whether current mood and interest/pleasure ratings in adults with moderate to profound intellectual disabilities were predictive of challenging behaviour [self-injurious behaviour (SIB), aggressive/destructive behaviour and stereotypic behaviour] and vice versa. In this combined cross-sectional and longitudinal study, staff members of a Hungarian residential facility completed translated versions of the Behaviour Problems Inventory-Short Form (BPI-S), the Challenging Behaviour Interview (CBI) and the Mood, Interest and Pleasure Questionnaire-Short Form (MIPQ-S) for 50 participants at two time points, approximately 4 to 5 months apart. Bivariate correlations from data concurrently assessed at Time-1 showed significant linear relationships between the SIB (both frequency and severity scores) and Interest/Pleasure sub-scales, and the Aggressive/Destructive Behaviour (severity scores) and the MIPQ-S Mood sub-scales (unadjusted for multiple correlations). All of these effects were found with the BPI-S data, but not with the CBI. Multiple regression analyses revealed that (1) low interest/pleasure assessed at Time-1 predicted high SIB (frequency and severity) at Time-2. (2) Interest/pleasure was not predictive of aggressive or stereotypic behaviour. (3) Mood at Time-1 did not predict any of the three types of behaviour problems at Time-2. (4) In reverse, high SIB (frequency and severity) at Time-1 predicted low interest/pleasure ratings at Time-2. (5) Surprisingly, frequent aggressive/destructive behaviour predicted high interest/pleasure. (6) Stereotypic behaviour scores at Time-1 did not predict interest/pleasure ratings at Time-2. Again, all of these effects were only found with the BPI-S data, but not with the CBI. Internal consistency, test-retest reliability and concurrent validity of the Hungarian versions of all three questionnaires had generally satisfactory outcomes. The fact that increasingly frequent and severe SIB was predicted by declining

    Full Text Available The main goal of early detection of hearing impairment in children is early intervention. There is growing interest in early detection of hearing impairment in developing countries. The main purpose of this study was to investigate the spoken language development in severe to profound hearing impaired children and compared their speech intelligibility with normal hearing children at the same age. Nine severe to profound hearing impaired children below 2 years old out of the primer 42 cases were selected for this survey. They receive aural habilitation and also speech therapy after beginning the speech production. Speech intelligibility test of these children was recorded on audio-tape, when they read five questions which can be answered with one word only, at the age of 4, 5 and 6 in comparison with 27 normal hearing children at the same age. At the age of 4 the mean speech intelligibility score of the studied group was 31.77% (SD 12.17 and the control was %96 (SD 2.23. At the age of 5, this score was %51.22 (SD 14.42, the control one 97.85% (SD 1.93. Finally at age 6 it was 72% (SD 18.97 for hearing–impaired group and 99.22% (SD 1.18 in control one. Severe to profound hearing impaired children acquired spoken language but not at the same level. In general, their speech development showed about 2 to 3 years delay. Their speech intelligibility was acceptable for severe group around the age 6 but almost semi–intelligible for profound group at the same age.

    The mutations of GJB2, SLC26A4, and mtDNA12SrRNA are the most common inherited causes of nonsyndromic sensorineural hearing loss (NSHL) in China, yet previous genetic screenings were mainly carried on patients with moderate-to-profound impairment. We aimed to detect the mutation frequencies in NSHL population within a more specified range of severity. Patients with profound NSHL who had undergone cochlear implantation in the Shandong Provincial Hospital (Shandong, China) were recruited. The majority (n  =  472) were between 0.7 and 6 years old, and the remaining (n  =  63) were between 6 and 70 years old. In total, 115 mutation alleles of the three genes were screened with SNP scan assay. Of the patients, 19.44% (104/535) were found to have GJB2 mutations, and the most common allele was c.235delC, followed by c.299_300delAT and c.109G>A. SLC26A4 mutations were detected in 13.46% patients (72/535), and the most common allele was c.919-2A>G (IVS7-2A>G), followed by c.1174A>T and c.2168A>G. Seven patients (1.31%) carried mutations in mtDNA12SrRNA, with the alleles of m.1555A>G and m.1494C>T. We found the allele frequency of c.109G>A (GJB2) was relatively lower in the profound NSHL population in comparison to the moderate-to-profound ones, and the c.1174A>T (SLC26A4) relatively higher. It suggests those mutations may be connected with the degree of deafness, which needs more observations and analyses to support. © 2017 John Wiley & Sons Ltd/University College London.

  16. New speech tests reveal benefit of wide-dynamic-range, fast-acting compression for consonant discrimination in children with moderate-to-profound hearing loss.

    2003-10-01

    Fast-acting, wide-dynamic-range compression (WDRC) has been shown to give better discrimination of soft speech and shouted speech than linear amplification for moderately hearing-impaired young adults. For severe and profound hearing losses, higher compression ratios are needed. The resultant distortion of the temporal envelope and reduced modulation depth may offset improvements in audibility offered by WDRC. This study compares the effectiveness of WDRC and linear amplification for children with different degrees of hearing loss. Pre-recorded tests of closed-set consonant confusions and open-set word recognition were developed to assess performance. Three groups of subjects (aged 4-14 years) with moderate (51-70 dB), severe (71-90 dB) and profound (91-115 dB) hearing loss were fitted with hearing aids programmed with WDRC or linear amplification. The frequency response was adjusted to match each child's own hearing aid prescription. For each group, stimuli were presented both in quiet and in noise at levels chosen to avoid floor and ceiling effects. Consonant confusion scores for the profound and severe groups combined and for the moderate group were significantly better with WDRC than with linear amplification. Open-set test results showed greater variability. Although mean scores were higher for WDRC than for linear processing, the effects were of marginal statistical significance.

    Early identification of severe/profound childhood hearing loss (HL) gives these children access to hearing devices and early intervention to facilitate improved speech and language outcomes. Predicting which infants will go on to achieve such outcomes remains difficult. This study describes clinician identified malleable and non-malleable factors that may influence speech and language outcomes for children with severe/profound HL. Semi-structured interviews were conducted with six experienced auditory verbal clinicians. A collective case study design was implemented. The interviews were transcribed and coded into themes using constant comparative analysis. Clinicians identified that, for children with severe/profound HL, early identification, early amplification and commencing auditory-verbal intervention under 6 months of age may facilitate child progress. Possible barriers were living in rural/remote areas, the clinicians' lack of experience and confidence in providing intervention for infants under age 6-months and belonging to a family with a culturally and linguistically diverse (CALD) background. The results indicate that multiple factors need to be considered by clinicians working with children with HL and their families to determine how each child functions within their own environment and personal contexts, consistent with the International Classification of Functioning, Disability and Health (ICF) framework. Such an approach is likely to empower clinicians to carefully balance potential barriers to, and facilitators of, optimal speech and language outcomes for all children with HL.

  18. How musical engagement promotes well-being in education contexts: The case of a young man with profound and multiple disabilities

    Students with profound intellectual disabilities disorders (IDDs) have the right to participate in educational opportunities that recognize their unique resources and needs, as do all children. Because of their specific communication challenges, positive relationships with attentive communication partners are critical for success. In fact, the power of positive relationships in schools is recognized to be connected to student well-being more broadly. This article examines the case of one young man with profound IDD and his relationship with his music therapist using a duo-ethnographic informed paradigmatic case study. Video analysis based on multi-voice perspectives is used to generate hermeneutic phenomenological findings to closely examine the relationship between a young man with profound IDD and a music therapist. The voices of four allied health researchers were also gathered to inform the authors’ construction of an informed commentary on the phenomenon. The results suggest that the essence lay in a combination of attentive, responsive and creative being with the other person over time. Four principles of musical engagement were identified in the video footage as critical to the meaningful relationships through music: the music therapist listens; the music therapist takes responsibility for structure; spontaneous initiation is sought from the young person; and the relationship is built over time. These concepts are contextualized within a discussion of student well-being that is underpinned by positive relationships and leads to students achieving their full potential within diverse school contexts.

    Profound acidemia impairs cellular and organ function and consequently should be associated with an increased risk of mortality in critically ill humans and animals. Neonatal diarrhea in calves can result in potentially serious metabolic derangements including profound acidemia due to strong ion (metabolic) acidosis, hyper-D-lactatemia, hyper-L-lactatemia, azotemia, hypoglycemia, hyperkalemia and hyponatremia. The aim of this retrospective study was to assess the prognostic relevance of clinical and laboratory findings in 1,400 critically ill neonatal calves with diarrhea admitted to a veterinary teaching hospital. The mortality rate was 22%. Classification tree analysis indicated that mortality was associated with clinical signs of neurologic disease, abdominal emergencies, cachexia, orthopedic problems such as septic arthritis, and profound acidemia (jugular venous blood pH study population. We conclude that laboratory values (except jugular venous blood pH < 6.85) are of limited value for predicting outcome in critically ill neonatal calves with diarrhea. In contrast, the presence of specific clinical abnormalities provides valuable prognostic information.

    To analyze speech in children with profound hearing loss following congenital cytomegalovirus (cCMV) infection with cochlear implantation (CI) before the age of 3 years. In a cohort of 15 children with profound hearing loss, speech perception, production and intelligibility were assessed before and 3 years after CI; variables impacting results were explored. Post-CI, median word recognition was 74% on closed-list and 48% on open-list testing; 80% of children acquired speech production; and 60% were intelligible for all listeners or listeners attentive to lip-reading and/or aware of the child's hearing loss. Univariate analysis identified 3 variables (mean post-CI hearing threshold, bilateral vestibular areflexia, and brain abnormality on MRI) with significant negative impact on the development of speech perception, production and intelligibility. CI showed positive impact on hearing and speech in children with post-cCMV profound hearing loss. Our study demonstrated the key role of maximizing post-CI hearing gain. A few children had insufficient progress, especially in case of bilateral vestibular areflexia and/or brain abnormality on MRI. This led us to suggest that balance rehabilitation and speech therapy should be intensified in such cases. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Students with profound intellectual disabilities disorders (IDDs) have the right to participate in educational opportunities that recognize their unique resources and needs, as do all children. Because of their specific communication challenges, positive relationships with attentive communication partners are critical for success. In fact, the power of positive relationships in schools is recognized to be connected to student well-being more broadly. This article examines the case of one young man with profound IDD and his relationship with his music therapist using a duo-ethnographic informed paradigmatic case study. Video analysis based on multi-voice perspectives is used to generate hermeneutic phenomenological findings to closely examine the relationship between a young man with profound IDD and a music therapist. The voices of four allied health researchers were also gathered to inform the authors' construction of an informed commentary on the phenomenon. The results suggest that the essence lay in a combination of attentive, responsive and creative being with the other person over time. Four principles of musical engagement were identified in the video footage as critical to the meaningful relationships through music: the music therapist listens; the music therapist takes responsibility for structure; spontaneous initiation is sought from the young person; and the relationship is built over time. These concepts are contextualized within a discussion of student well-being that is underpinned by positive relationships and leads to students achieving their full potential within diverse school contexts.

  2. Assumptions of Decision-Making Capacity: The Role Supporter Attitudes Play in the Realisation of Article 12 for People with Severe or Profound Intellectual Disability

    2016-02-01

    Full Text Available The United Nations Convention on the Rights of Persons with Disabilities (UNCRPD was the first legally binding instrument explicitly focused on how human rights apply to people with disability. Amongst their obligations, consistent with the social model of disability, the Convention requires signatory nations to recognise that “…persons with disabilities enjoy legal capacity on an equal basis with others in all aspects of life” and mandates signatory nations to develop “…appropriate measures to provide access by persons with disability to the support they may require in exercising their legal capacity”. The Convention promotes supported decision-making as one such measure. Although Australia ratified the UNCRPD in 2008, it retains an interpretative declaration in relation to Article 12 (2, 3, 4, allowing for the use of substituted decision-making in situations where a person is assessed as having no or limited decision-making capacity. Such an outcome is common for people with severe or profound intellectual disability because the assessments they are subjected to are focused on their cognition and generally fail to take into account the interdependent nature of human decision-making. This paper argues that Australia’s interpretative declaration is not in the spirit of the Convention nor the social model of disability on which it is based. It starts from the premise that the intention of Article 12 is to be inclusive of all signatory nations’ citizens, including those with severe or profound cognitive disability. From this premise, arises a practical need to understand how supported decision-making can be used with this group. Drawing from evidence from an empirical study with five people with severe or profound intellectual disability, this paper provides a rare glimpse on what supported decision-making can look like for people with severe or profound intellectual disability. Additionally, it describes the importance of

  3. The Consequences of Human Behavior

    Full Text Available Human behavior is founded on a complex interaction of influences that derive from sources both extraneous and intrinsic to the brain. It is the ways these various influences worked together in the past to fashion modern human cognition that can help elucidate the probable course of future human endeavor. A particular concern of this chapter is the way cognition has been shaped and continues to depend on prevailing environmental and ecological conditions. Whether the human predicament can be regarded simply as another response to such conditions similar to that of other organisms or something special will also be addressed. More specifically, it will be shown that, although the highly artificial niche in which most humans now live has had profound effects on ways of thinking, constraints deriving from a shared evolutionary heritage continue to have substantial effects on behavior. The way these exigencies interact will be explored in order to understand the implications for the future wellbeing of humanity.

    Poor flow properties hinder the easy handling of powders during industrial-scale processing. In this work, we show that powder flow can be substantially improved by reducing the cohesion of powders by coating them with nanosized guest particles. We further show that comilling is an efficient process for nanocoating. We have systematically investigated the effects of total number of comilling cycles (10-70 cycles) and silica loading (0-1.0 wt %) on the flow behavior of a highly cohesive and poorly flowing grade of microcrystalline cellulose powder (Avicel PH105). Optimum flow enhancement has been achieved with 1.0 wt % silica loading at 40 comilling cycles. The flow properties of nanocoated Avicel PH105 are comparable to those of Avicel PH102, which exhibits adequate flowability for processing on a high-speed tablet press. Comilling is fast and suitable for continuous processing. It shows potential for addressing industrial powder handling problems caused by poor powder flow properties.

  5. Clinical signs, profound acidemia, hypoglycemia, and hypernatremia are predictive of mortality in 1,400 critically ill neonatal calves with diarrhea.

    Directory of Open Access Journals (Sweden)

    Florian M Trefz

    Full Text Available Profound acidemia impairs cellular and organ function and consequently should be associated with an increased risk of mortality in critically ill humans and animals. Neonatal diarrhea in calves can result in potentially serious metabolic derangements including profound acidemia due to strong ion (metabolic acidosis, hyper-D-lactatemia, hyper-L-lactatemia, azotemia, hypoglycemia, hyperkalemia and hyponatremia. The aim of this retrospective study was to assess the prognostic relevance of clinical and laboratory findings in 1,400 critically ill neonatal calves with diarrhea admitted to a veterinary teaching hospital. The mortality rate was 22%. Classification tree analysis indicated that mortality was associated with clinical signs of neurologic disease, abdominal emergencies, cachexia, orthopedic problems such as septic arthritis, and profound acidemia (jugular venous blood pH < 6.85. When exclusively considering laboratory parameters, classification tree analysis identified plasma glucose concentrations < 3.2 mmol/L, plasma sodium concentrations ≥ 151 mmol/L, serum GGT activity < 31 U/L and a thrombocyte count < 535 G/L as predictors of mortality. However, multivariable logistic regression models based on these laboratory parameters did not have a sufficiently high enough sensitivity (59% and specificity (79% to reliably predict treatment outcome. The sensitivity and specificity of jugular venous blood pH < 6.85 were 11% and 97%, respectively, for predicting non-survival in this study population. We conclude that laboratory values (except jugular venous blood pH < 6.85 are of limited value for predicting outcome in critically ill neonatal calves with diarrhea. In contrast, the presence of specific clinical abnormalities provides valuable prognostic information.

    To assess the feasibility of conducting a randomised controlled trial to determine the effectiveness of a twenty-week power-assisted exercise intervention in people with profound intellectual and multiple disabilities and to evaluate the potential beneficial effects of this intervention. Pilot randomised controlled trial. A large-scale twenty-four-hour residential facility in the Netherlands. Thirty-seven persons with profound intellectual and multiple disabilities. Participants in the intervention group received a power-assisted exercise intervention three times a week for thirty minutes over a twenty-week period. Participants in the control group received care as usual. Trial feasibility by recruitment process and outcomes completion rates; intervention feasibility by programme compliance rates; potential outcomes by functional abilities, alertness, body composition, muscle tone, oxygen saturation, cardiovascular fitness and quality of life. Thirty-seven participants were recruited ( M age = 32.1, SD = 14.6) and were randomly allocated to intervention ( n = 19) and control ( n = 18) groups. Programme compliance rates ranged from 54.2% to 97.7% with a mean (SD) of 81.5% (13.4). Oxygen saturation significantly increased in the intervention group. Standardised effect sizes on the difference between groups in outcome varied between 0.02 and 0.62. The power-assisted exercise intervention and the trial design were feasible and acceptable to people with profound intellectual and multiple disabilities living in a residential facility. This pilot study suggests that the intervention improves oxygen saturation, but further implementation with the aim of improving other outcomes should be considered with caution.

    This paper describes the development of Vibroacoustic Sound Therapy, an approach which is being developed for use in special schools for children with profound and multiple learning difficulties, and in long-term care homes for the elderly and the elderly mentally infirm. Using non-invasive techniques and music/sound technology, children and the elderly are being empowered and enabled to (re)discover self expression and communication skills. Two case studies drawn from the world of the young disabled, and from the elderly, illustrate the potential for improving quality of life and well-being in these institutional settings.

    A male patient with profound mental retardation, athetosis, nystagmus, and severe congenital hypotonia (Duchenne muscular dystrophy [DMD]) was previously shown to carry a pericentric inversion of the X chromosome, 46,Y,inv(X)(p21.2q22.2). His mother carried this inversion on one X allele. The patient's condition was originally misdiagnosed as cerebral palsy, and only later was it diagnosed as DMD. Because the DMD gene is located at Xp21.2, which is one breakpoint of the inv(X), and because its defects are rarely associated with severe mental retardation, the other clinical features of this patient were deemed likely to be associated with the opposite breakpoint at Xq22. Our precise molecular-cytogenetic characterization of both breakpoints revealed three catastrophic genetic events that had probably influenced neuromuscular and cognitive development: deletion of part of the DMD gene at Xp21.2, duplication of the human proteolipid protein gene (PLP) at Xq22.2, and disruption of a novel gene. The latter sequence, showing a high degree of homology to the Sec4 gene of yeast, encoded a putative small guanine-protein, Ras-like GTPase that we have termed "RLGP." Immunocytochemistry located RLGP at mitochondria. We speculate that disruption of RLGP was responsible for the patient's profound mental retardation.

    Full Text Available Objective. To investigate the treatment outcome of a simultaneous labyrinthectomy and cochlear implantation in patients with single-sided Ménière’s disease and profound sensorineural hearing loss. Study Design. Prospective study. Method. Five patients with single-sided Ménière’s disease with active vertigo and functional deafness were included. In all cases, simultaneous cochlear implantation combined with labyrinthectomy surgery was performed. The outcome has been evaluated by the Dizziness Handicap Inventory (DHI and speech recognition. Results. The combined labyrinthectomy and cochlear implantation led in all patients to a highly significant reduction of dizziness up to a restitutio ad integrum. After activation of the cochlear implant and rehabilitation, a mean monosyllabic speech understanding of 69% at 65 dB was observed. Conclusion. For patients with single-sided Ménière’s disease and profound sensorineural hearing loss the simultaneous labyrinthectomy and cochlear implantation are efficient method for the treatment of vertigo as well as the rehabilitation of the auditory system.

  10. Oxytocin during development: possible organizational effects on behavior

    Directory of Open Access Journals (Sweden)

    Heather K Caldwell

    2015-05-01

    Full Text Available Oxytocin (Oxt is a neurohormone known for its physiological roles associated with lactation and parturition in mammals. Oxt can also profoundly influence mammalian social behaviors such as affiliative, parental, and aggressive behaviors. While the acute effects of Oxt signaling on adult behavior have been heavily researched in many species, including humans, the developmental effects of Oxt on the brain and behavior is just beginning to be explored. There is evidence that Oxt in early postnatal and peripubertal development, and perhaps during prenatal life, affects adult behavior by altering neural structure and function. However, the specific mechanisms by which this occurs remain unknown. Thus, this review will detail what is known about how developmental Oxt impacts behavior as well as specific neurochemicals and neural substrates that are important to these behaviors.

  11. Behavioral and Pharmacogenetics of Aggressive Behavior

    2013-01-01

    Serotonin (5-HT) has long been considered as a key transmitter in the neurocircuitry controlling aggression. Impaired regulation of each subtype of 5-HT receptor, 5-HT transporter, synthetic and metabolic enzymes has been linked particularly to impulsive aggression. The current summary focuses mostly on recent findings from pharmacological and genetic studies. The pharmacological treatments and genetic manipulations or polymorphisms of a specific target (e.g., 5-HT1A receptor) can often result in inconsistent results on aggression, due to “phasic” effects of pharmacological agents vs “trait”-like effects of genetic manipulations. Also, the local administration of a drug using the intracranial microinjection technique has shown that activation of specific subtypes of 5-HT receptors (5-HT1A and 5-HT1B) in mesocorticolimbic areas can reduce species-typical and other aggressive behaviors, but the same receptors in the medial prefrontal cortex or septal area promote escalated forms of aggression. Thus, there are receptor populations in specific brain regions that preferentially modulate specific types of aggression. Genetic studies have shown important gene × environment interactions; it is likely that the polymorphisms in the genes of 5-HT transporters (e.g., MAO A) or rate-limiting synthetic and metabolic enzymes of 5-HT determine the vulnerability to adverse environmental factors that escalate aggression. We also discuss the interaction between the 5-HT system and other systems. Modulation of 5-HT neurons in the dorsal raphe nucleus by GABA, glutamate, and CRF profoundly regulate aggressive behaviors. Also, interactions of the 5-HT system with other neuropeptides (arginine vasopressin, oxytocin, neuropeptide Y, opioid) have emerged as important neurobiological determinants of aggression. Studies of aggression in genetically modified mice identified several molecules that affect the 5-HT system directly (e.g., Tph2, 5-HT1B, 5-HT transporter, Pet1, MAOA) or

    2013-12-01

    Knowledge about the preferences and abilities of children with profound intellectual and multiple disabilities (PIMDs) is crucial for providing appropriate activities. Multi-sensory storytelling (MSST) can be an ideal activity for gathering such knowledge about children with PIMDs. The aim of this study was to analyse whether using MSST did lead to changes in teachers' knowledge about preferences and abilities and whether this knowledge was then applied in practice. Three dyads of children with PIMDs and their teachers read an MSST book 20 times during a 10-week period. A questionnaire designed to identify the teachers' current knowledge was filled in before the 1st and again after the 10th and 20th reading sessions. Also, the teachers were asked for their opinion about their newly gathered knowledge. In all three cases, changes in the teachers' knowledge were observed. However, teachers are insufficiently aware of their new knowledge and do not apply it in practice.

    Nine children with severe-profound prelingual hearing loss and single-word reading scores not more than 10 months behind chronological age (Good Readers) were matched with 9 children whose reading lag was at least 15 months (Poor Readers). Good Readers had significantly higher spelling and reading comprehension scores. They produced significantly more phonetic errors (indicating the use of phonological coding) and more often correctly represented the number of syllables in spelling than Poor Readers. They also scored more highly on orthographic awareness and were better at speech reading. Speech intelligibility was the same in the two groups. Cluster analysis revealed that only three Good Readers showed strong evidence of phonetic coding in spelling although seven had good representation of syllables; only four had high orthographic awareness scores. However, all 9 children were good speech readers, suggesting that a phonological code derived through speech reading may underpin reading success for deaf children.

    OBJECTIVE. To evaluate technology-assisted programmes for enabling a woman and a man with brain injury and profound multiple disabilities to acquire leisure engagement. METHOD. The technology for the woman (Study I) involved a portable computer with mouse, a Clicker 4 software package, a touch/pressure microswitch, and an interface to connect the Clicker with the microswitch. This technology allowed the woman to choose with a simple hand response among four stimulus categories (e.g., watching a film and interacting with others), each of which included several alternatives. The technology for the man (Study II) involved a computer-based choice system that allowed him to select preferred songs through a microswitch-aided finger-movement response. RESULTS. Data showed that the two participants learned to use the technology available and selected among the stimulus events thus reaching positive leisure engagement. CONCLUSION. Technology-assisted programmes may provide persons with acquired brain injury and multiple disabilities leisure engagement opportunities.

    The aim of this study was to assess the effectiveness of a family-centered care (FCC) intervention provided by an advanced practice nurse (APN) for parents of children with profound disabilities undergoing surgery. In a quasi-experimental design, we used the MPOC-20 to assess satisfaction with FCC and interviews to identify potential mechanisms for improving satisfaction. There was a positive effect on the MPOC-20 domain "general information," albeit with a small effect size (Cohen's d = 0.35). The interviewed parents expected additional support. Emphasis should be placed on providing comprehensive care coordination by an experienced APN. Shared care management is crucial in improving FCC. © 2017 Wiley Periodicals, Inc.

    Dietary lipids are known to affect the composition of the biological membrane and functions that are involved in cell death and survival. The mitochondrial respiratory chain enzymes are membrane protein complexes whose function depends on the composition and fluidity of the mitochondrial membrane lipid. The present study aimed at investigating the impact of different nutritional patterns of dietary lipids on liver mitochondrial functions. A total of forty-eight Wistar male rats were divided into six groups and fed for 12 weeks with a basal diet, lard diet or fish oil diet, containing either 50 or 300 g lipid/kg. The 30 % lipid intake increased liver NEFA, TAG and cholesterol levels, increased mitochondrial NEFA and TAG, and decreased phospholipid (PL) levels. SFA, PUFA and unsaturation index (UI) increased, whereas MUFA and trans-fatty acids (FA) decreased in the mitochondrial membrane PL in 30 % fat diet-fed rats compared with 5 % lipid diet-fed rats. PL UI increased with fish oil diet v. basal and lard-rich diets, and PL trans-FA increased with lard diet v. basal and fish oil diets. The 30 % lipid diet intake increased mitochondrial membrane potential, membrane fluidity, mitochondrial respiration and complex V activity, and decreased complex III and IV activities. With regard to lipid quality effects, β-oxidation decreased with the intake of basal or fish oil diets compared with that of the lard diet. The intake of a fish oil diet decreased complex III and IV activities compared with both the basal and lard diets. In conclusion, the characteristics and mitochondrial functions of the rat liver mitochondrial membrane are more profoundly altered by the quantity of dietary lipid than by its quality, which may have profound impacts on the pathogenesis and development of non-alcoholic fatty liver disease.

    As overall survival improves, individuals with HIV infection become susceptible to other chronic diseases, including accelerated chronic obstructive pulmonary disease (COPD). To determine whether individuals with HIV-associated COPD exhibit dysregulated lung mucosal T-cell immunity compared with control subjects. Using flow cytometry, we evaluated peripheral blood and lung mucosal T-cell immunity in 14 HIV(+)COPD(+), 13 HIV(+)COPD(-), and 7 HIV(-)COPD(+) individuals. HIV(+)COPD(+) individuals demonstrated profound CD4(+) T-cell depletion with reduced CD4/CD8 T-cell ratios in bronchoalveolar lavage-derived lung mononuclear cells, not observed in peripheral blood mononuclear cells, and diminished CD4(+) T cell absolute numbers, compared with control subjects. Furthermore, HIV(+)COPD(+) individuals demonstrated decreased pulmonary HIV-specific and staphylococcal enterotoxin B-reactive CD4(+) memory responses, including loss of multifunctionality, compared with HIV(+)COPD(-) control subjects. In contrast, lung mucosal HIV-specific CD8(+) T-cell responses were preserved. Lung CD4(+) T cells from HIV(+)COPD(+) individuals expressed increased surface Fas death receptor (CD95) and programmed death-1, but similar bronchoalveolar lavage viral loads as control subjects. However, programmed death-1 expression inversely correlated with HIV-specific lung CD4(+)IFN-γ(+) T-cell responses, suggesting functional exhaustion. Moreover, lung CD4(+) T cells from HIV(+)COPD(+) patients demonstrated increased basal and HIV antigen-induced expression of the early apoptosis marker annexin V compared with control subjects, which was significantly attenuated with anti-Fas blockade. Lastly, lung mucosal, but not blood, CD4(+)/CD8(+) ratios from HIV(+) patients significantly correlated with the FEV1, but not in HIV(-)COPD(+) patients. Together, our results provide evidence for profound lung mucosal CD4(+) T-cell depletion via a Fas-dependent activation-induced cell death mechanism, along with

    Participation throughout one's life plays a significant role for development and emotional well-being. For this reason, there is a need to identify ways to facilitate participation in family activities for children and adolescents with profound intellectual and multiple disabilities (PIMD). The study design was qualitative and explorative, based on semi structured interviews with 11 parents and 9 personal assistants of children with PIMD. The interviews revealed participation-facilitating strategies relating to the children's/adolescent's proximal environment, such as "Availability and acceptability of the activity", "Good knowledge about the child" and a "A positive attitude of people close to the child", as well as strategies related to the children/adolescents themselves: "Sense of belonging", "Possible for the child/adolescent to understand", "Opportunities to influence" and "Feeling of being needed". Children and adolescents with PIMD are dependent on support obtained through their environment. The identified strategies, individually adapted through awareness and knowledge by the parents and the personal assistants, provide important evidence to assist our understanding in gaining understanding about how to improve participation in family activities of children and adolescents with PIMD. Participation-facilitating strategies related to the child/adolescent and his or her proximal environments are identified to improve participation in children and adolescents with profound intellectual and multiple disabilities (PIMD). Examples of strategies for the child's/adolescents' proximal environment include "good knowledge about the child/adolescent", and, for the child/adolescent, include creating "sense of belonging" and "opportunities to influence". Identifying and making these strategies explicit may assist in enhancing the participation of children and adolescents with PIMD in family activities. People in the child's/adolescent's proximal environment need to set

    Full Text Available Abstract Background A detailed behavioral profile associated with focal congenital malformation of the ventromedial prefrontal cortex (vmPFC has not been reported previously. Here we describe a 14 year-old boy, B.W., with neurological and psychiatric sequelae stemming from focal cortical malformation of the left vmPFC. Case Presentation B.W.'s behavior has been characterized through extensive review Patience of clinical and personal records along with behavioral and neuropsychological testing. A central feature of the behavioral profile is severe antisocial behavior. He is aggressive, manipulative, and callous; features consistent with psychopathy. Other problems include: egocentricity, impulsivity, hyperactivity, lack of empathy, lack of respect for authority, impaired moral judgment, an inability to plan ahead, and poor frustration tolerance. Conclusions The vmPFC has a profound contribution to the development of human prosocial behavior. B.W. demonstrates how a congenital lesion to this cortical region severely disrupts this process.

    In today's healthcare environment, characterized by downsizing, restructuring, mergers, and acquisitions, organizational cultures and employees are experiencing rapid--and often tense--changes. Ritual can facilitate change by acknowledging it and allowing the grieving process to take its course. The success of an organizational culture change can depend on whether the organization and its members have been given an opportunity to grieve. Until they grieve their losses, people cannot embrace the new. Organizational leaders who have survived downsizing must come to grips with their own survivor status first and then lead others in the organization through the current painful but irrevocable shift in their relationship to the organization. The use of ritual helps organizational survivors see the connection between the grieving process and their survivor symptoms of denial, anger, depression, guilt, fear, insecurity, anxiety, and uncertainty. A good ritual should allow those present to rise above barriers that separate, worries that overburden, and blindness that limits and to gather as one with God. As a rule, a good ritual is participative and recognizes the audience's diversity. The ritual should not just address those present but invite them to act, pray, or sing. Ritual is an important way to provide a structure that allows people to express their emotions. For leaders, it can be a visible way to acknowledge grief and show support for organizational members. For ritual to have any meaning, key leaders need to be present and perhaps have a role in the creation and enactment of the ritual.

    Full Text Available Background. 3,4-Methylenedioxymethamphetamine (MDMA or ecstasy is a synthetic drug that is commonly abused for its stimulant and euphoric effects. Adverse MDMA effects include hyperthermia, psychomotor agitation, hemodynamic compromise, renal failure, hyponatremia, and coma. However, endogenous hyperinsulinemia with severe persistent hypoglycemia has not been reported with MDMA use. Case Report. We report the case of a 29-year-old woman who remained severely hypoglycemic requiring continuous intravenous infusion of high-dose dextrose solutions for more than 24 hours after MDMA intoxication. Serum insulin and C-peptide levels confirmed marked endogenous hyperinsulinemia as the cause of the severe hypoglycemia. Why Should an Emergency Physician Be Aware of This? Immediate and frequent monitoring of blood glucose should be instituted in patients presenting with MDMA ingestion particularly if found to be initially hypoglycemic. Early recognition can help prevent the deleterious effects of untreated hypoglycemia that can add to the morbidity from MDMA use. Clinicians need to be aware of this side effect of MDMA so they can carefully monitor and treat it, especially in patients presenting with altered mental status.

    Full Text Available Background and Aim: Learning Language is a skill which is acquired in early childhood. So, language gradually developed and new words and new structures slowly added to language knowledge. Hearing sense is the most important acquisition for of language and hearing disorder is a barrier for natural language acquiring .The purpose of this study is comparison between morphological and syntactic features of 4 to 5 years old severe to profound hearing impaired and normal children. Materials and Method: This cross-sectional study performed on 10 normal-hearing children with mean age of 4-5, from Gazvin kindergartens and 10 hearing impaired children with similar IQ and age from Nioosha Rehabilitation Center. The language and non language information was received by spontaneous and descriptive speech, and questionnaire, respectively and for comparing syntax comprehension, Specific language impairment test was used. Then these results were compared between two groups. Results: Difference between spontaneous speech and descriptive speech in hearing impaired child is just like normal child. These differences are that the number of utterance, the mean of lexical morpheme, functional morpheme in spontaneous speech is greater than descriptive speech but the mean length of utterance and richness of vocabulary in descriptive speech is greater than spontaneous speech. Mean of lexical morpheme, functional morpheme and richness of vocabulary related to morphological part and the number of utterance, the mean length of utterance and syntax comprehension related to syntax, in spontaneous and descriptive speech of normal children speech is greater than hearing impaireds`. Conclusion: According to recent researches, compared with normal child, the hearing impaired child nearly never to reach equal level, and for this reason, training for this group is necessary. It is concluded that although these children have severe to profound hearing loss they are developing their

    The objective of this investigation was to describe the language growth of children with severe or profound hearing loss with cochlear implants versus those children with the same degree of hearing loss using hearing aids. A prospective longitudinal observation and analysis. University of Colorado Department of Speech Language and Hearing Sciences. There were 87 children with severe-to-profound hearing loss from 48 to 87 months of age. All children received early intervention services through the Colorado Home Intervention Program. Most children received intervention services from a certified auditory-verbal therapist or an auditory-oral therapist and weekly sign language instruction from an instructor who was deaf or hard of hearing and native or fluent in American Sign Language. The Test of Auditory Comprehension of Language, 3rd Edition, and the Expressive One Word Picture Vocabulary Test, 3rd Edition, were the assessment tools for children 4 to 7 years of age. The expressive language subscale of the Minnesota Child Development was used in the infant/toddler period (birth to 36 mo). Average language estimates at 84 months of age were nearly identical to the normative sample for receptive language and 7 months delayed for expressive vocabulary. Children demonstrated a mean rate of growth from 4 years through 7 years on these 2 assessments that was equivalent to their normal-hearing peers. As a group, children with hearing aids deviated more from the age equivalent trajectory on the Test of Auditory Comprehension of Language, 3rd Edition, and the Expressive One Word Picture Vocabulary Test, 3rd Edition, than children with cochlear implants. When a subset of children were divided into performance categories, we found that children with cochlear implants were more likely to be "gap closers" and less likely to be "gap openers," whereas the reverse was true for the children with hearing aids for both measures. Children who are educated through oral-aural combined with

    The field of behavioral genetics has engendered a host of moral and social concerns virtually since its inception. The policy implications of a genetic basis for behaviors are widespread and extend beyond the clinic to the socially important realms of education, criminal justice, childbearing, and child rearing. The development of new techniques and analytic approaches, including whole-genome sequencing, noninvasive prenatal genetic testing, and optogenetics, has clearly changed the study of behavioral genetics. However, the social context of biomedical research has also changed profoundly over the past few decades, and in ways that are especially relevant to behavioral genetics. The ever-widening scope of behavioral genetics raises ethical, legal, social, and policy issues in the potential new applications to criminal justice, education, the military, and reproduction. These issues are especially critical to address because of their potentially disproportionate effects on vulnerable populations such as children, the unborn, and the incarcerated.

    Growing evidence has begun to elucidate the contribution of epigenetic mechanisms in the modulation and maintenance of gene expression and behavior. Histone acetylation is one such epigenetic mechanism, which has been shown to profoundly alter gene expression and behaviors. In this review, we begin with an overview of the major epigenetic mechanisms including histones acetylation. We next focus on recent evidence about the influence of environmental stimuli on various motivated behaviors through histone acetylation and highlight how histone deacetylase inhibitors can correct some of the pathologies linked to motivated behaviors including substance abuse, feeding and social attachments. Particularly, we emphasize that the effects of histone deacetylase inhibitors on motivated behaviors are time and context-dependent. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Games between staff and people with intellectual disabilities serve to promote social engagement and inclusion. However, when the person has limited and idiosyncratic communicative abilities, it may be hard to gauge what his/her own view of the matter is. We examine video-taped records of two episodes in which a staff member of a group home prompted a resident with profound intellectual disabilities to play a verbal and a non-verbal 'game'. We examine how the staff member in these two cases designs her actions to solve the dilemma she faces between, on the one hand, abandoning an activity when the resident does not provide clear indications that she/he wants to continue or, on the other hand, persisting with it until the resident begins to enjoy it or, at least, participate more fully. The solution lies in a pervasive institutional practice: treat resistance or ambiguity as temporary reluctance. We discuss these interactions as examples of how principles of empowerment, inclusion and independence play out in the details of everyday interaction.

    Co-Fe layered double hydroxides at different Fe/Co ratios were synthesized from brucite-like Co(2+)(1-x)Fe(2+)(x)(OH)(2) (0 ≤ x ≤ 1/3) via oxidative intercalation reaction using an excess amount of iodine as the oxidizing agent. A new redoxable species: triiodide (I(3)(-)), promoted the formation of single-phase Co-Fe LDHs. The results point to a general principle that LDHs with a characteristic ratio of total trivalent and divalent cations (M(3+)/M(2+)) at 1/2 may be the most stable in the oxidative intercalation procedure. At low Fe content, e.g., starting from Co(2+)(1-x)Fe(2+)(x)(OH)(2) (x triiodide and iodide into the interlayer gallery of as-transformed LDH phase, which profoundly impacted the relative intensity ratio of basal Bragg peaks as a consequence of the significant X-ray scattering power of triiodide. In combination with XRD simulation, the LDH structure model was constructed by considering both the host layer composition/charge and the arrangement of interlayer triiodide/iodide. The work provides a clear understanding of the thermodynamic and kinetic factors associated with the oxidative intercalation reaction and is helpful in elucidating the formation of LDH structure in general.

    Work preferences, life values, and personal views of top math/science graduate students (275 men, 255 women) were assessed at ages 25 and 35 years. In Study 1, analyses of work preferences revealed developmental changes and gender differences in priorities: Some gender differences increased over time and increased more among parents than among childless participants, seemingly because the mothers' priorities changed. In Study 2, gender differences in the graduate students' life values and personal views at age 35 were compared with those of profoundly gifted participants (top 1 in 10,000, identified by age 13 and tracked for 20 years: 265 men, 84 women). Again, gender differences were larger among parents. Across both cohorts, men appeared to assume a more agentic, career-focused perspective than women did, placing more importance on creating high-impact products, receiving compensation, taking risks, and gaining recognition as the best in their fields. Women appeared to favor a more communal, holistic perspective, emphasizing community, family, friendships, and less time devoted to career. Gender differences in life priorities, which intensify during parenthood, anticipated differential male-female representation in high-level and time-intensive careers, even among talented men and women with similar profiles of abilities, vocational interests, and educational experiences.

    Brain activation procedures associated with single photon emission tomography (SPET) have recently been developed in healthy controls and diseased patients in order to help in their diagnosis and treatment. We investigated the effects of a promontory test (PT) on the cerebral distribution of technetium-99m hexamethyl-propylene amine oxime ({sup 99m}Tc-HMPAO) in 7 profoundly deaf patients, 6 PT+ and PT-. The count variation in the temporal lobe was calculated on 6 coronal slices using the ratio (R{sub stimulation}-R{sub deprivation})/R{sub deprivation} where R=counts in the temporal lobe was observed in all patients and was higher in all patients with PT+ than in the patient with PT-. The problems of head positioning and resolution of the system were taken into account, and we considered that the maximal count increment was related to the auditory cortex response to the stimulus. Further clinical investigations with high-resolution systems have to be performed in order to validate this presurgery test in cochlear implant assessment. (orig.).

    In this work we describe the experimental protocol set up to obtain very good results in speech performance and in time course, with a subject presenting profound bilateral sensorineural hearing loss with low-frequencies preservation. We used a bimodal stimulation with a like-hybrid modality. Auditory functions have been analyzed by standard tonal and speech audiometry tests, and verbal perception test. The fitting protocol permitted the subject to reach a perception at 65 dB of 100% in a very short time. The subject showed a sufficient recovery of the language spectral information and a good integration of verbal information with high consonantal recognition is present. This case report shows the importance to realize a correct cochlear implant fitting and that, in the case of bimodal stimulation, it is very important to obtain the mutual adjustment of the two hearing aids. Moreover, this study enhances the importance of realizing a preservative surgery to make the most of cochlear implants capacity. © 2013.

    Behavior has a broad and central role in health. Behavioral interventions can be effectively used to prevent disease, improve management of existing disease, increase quality of life, and reduce healthcare costs. A summary is presented of evidence for these conclusions in cardiovascular disease/diabetes, cancer, and HIV/AIDS as well as with key risk factors: tobacco use, poor diet, physical inactivity, and excessive alcohol consumption. For each, documentation is made of (1) moderation of genetic and other fundamental biological influences by behaviors and social-environmental factors; (2) impacts of behaviors on health; (3) success of behavioral interventions in prevention; (4) disease management; (5) quality of life, and (6) improvements in the health of populations through behavioral health promotion programs. Evidence indicates the cost effectiveness and value of behavioral interventions, especially relative to other common health services as well as the value they add in terms of quality of life. Pertinent to clinicians and their patients as well as to health policy and population health, the benefits of behavioral interventions extend beyond impacts on a particular disease or risk factor. Rather, they include broad effects and benefits on prevention, disease management, and well-being across the life span. Among priorities for dissemination research, the application of behavioral approaches is challenged by diverse barriers, including socioeconomic barriers linked to health disparities. However, behavioral approaches including those emphasizing community and social influences appear to be useful in addressing such challenges. In sum, behavioral approaches should have a central place in prevention and health care of the 21st century. Copyright © 2011 American Journal of Preventive Medicine. Published by Elsevier Inc.

    Peer influence on students' maladaptive behaviors has been well documented; however, the influence on positive development is less acknowledged. The purpose of this study was to examine anonymous peer influence on college students' prosocial behavior, specifically behavior for the improvement of society (i.e., donating money or participating in social campaigns) via an experimental approach. The effects of indirect peer influence (IP) and direct peer influence (DP) on college students' prosocial behavior were examined. A total of 125 college students participated in an online survey and laboratory experiment. Self-reported helping behavior, social concern goals, and empathy were measured by the online survey. In the laboratory experiments, reading of a prosocial paragraph (IP) and confederates' prosocial behavior (DP) were manipulated. Participation in a signature campaign and money donation for illness were observed. Furthermore, 19 participants among those who donated were asked about their reasons for participating in such prosocial behavior. Prosocial behavior of anonymous peers (confederates) exerts a profound influence on college students' participation in a signature campaign and money donation, whereas the reading of a prosocial paragraph has no effect. Furthermore, no participants reported peer influence as a reason for engaging in prosocial behavior. This finding supports and extends recent research examining the positive impacts of anonymous peers on prosocial behavior. Prosocial behavior is not only a foundational and consistent aspect of personality, as previous studies report, but is also highly malleable and unstable in response to immediate situations.

    Lexical content is commonly understood to refer to the various categories of words that children produce and has been studied extensively in children with normal hearing. Unlike the hearing child, however, little is known about the word categories that make up the first lexicon of children with hearing loss (HL). Knowledge of the first lexicon is increasingly important, as infants with HL are now being detected through universal newborn hearing screening programs and fitted with hearing aids and cochlear implants in before 12 months of age. For these children, emergence of the first spoken words is a major milestone eagerly awaited by parents and one of the first verbal language goals of teachers and therapists working with such children. The purpose of this study was to evaluate the lexical content of the first 50 and 100 words produced by children with HL and to contrast this with that of a group of hearing children. Lexical content was compared in two groups of children: one group composed of 24 participants with severe profound or profound HL and a second group composed of 16 participants with normal hearing. Twenty-three participants in the HL group were fitted with a cochlear implant and one with bilateral hearing aids. All were "switched on" or fitted before 30 months of age. The Diary of Early Language (Di-EL) was used to collect a 100-word lexicon from each participant. All single word and frozen phrase data from each child's Di-EL were allocated to 1 of 15 word types grouped into four word categories (noun, predicate, grammatical, and paralexical), and the results were compared for both groups. The hearing and HL groups showed similar distributions of word categories, with nouns constituting the largest portion of the lexicon followed by predicates and paralexicals. Grammaticals made up the smallest portion of the lexicon. However, several significant differences were evident between the two groups. In both the 50- and 100-word lexicons, the hearing group

    Although a number of studies have assessed the effects of geological and climatic changes on species distributions in East Asian, we still have limited knowledge of how these changes have impacted avian species in south-western and southern China. Here, we aim to study paleo-climatic effects on an East Asian bird, two subspecies of black-throated tit (A. c. talifuensis-concinnus) with the combined analysis of phylogeography and Ecological Niche Models (ENMs). We sequenced three mitochondrial DNA markers from 32 populations (203 individuals) and used phylogenetic inferences to reconstruct the intra-specific relationships among haplotypes. Population genetic analyses were undertaken to gain insight into the demographic history of these populations. We used ENMs to predict the distribution of target species during three periods; last inter-glacial (LIG), last glacial maximum (LGM) and present. We found three highly supported, monophyletic MtDNA lineages and different historical demography among lineages in A. c. talifuensis-concinnus. These lineages formed a narrowly circumscribed intra-specific contact zone. The estimated times of lineage divergences were about 2.4 Ma and 0.32 Ma respectively. ENMs predictions were similar between present and LGM but substantially reduced during LIG. ENMs reconstructions and molecular dating suggest that Pleistocene climate changes had triggered and shaped the genetic structure of black-throated tit. Interestingly, in contrast to profound impacts of other glacial cycles, ENMs and phylogeographic analysis suggest that LGM had limited effect on these two subspecies. ENMs also suggest that Pleistocene climatic oscillations enabled the formation of the contact zone and thus support the refuge theory.

The girl, Akiko, was born in Belgium where her family was living at that time. After she was identified as deaf at birth, she and her parents were provided with support services. The family relocated to Japan when Akiko was 1 year 5 months of age. When she was 1 year 6 months of age Akiko underwent cochlear implantation. The cochlear implant device was activated when Akiko was 1 year 7 months of age. The parents routinely made video recordings of Akiko interacting with family members and teachers at home and at school. The video recordings taken by the parents used as the data for this study contained scenes of Akiko from the time she was 3 months of age until she was 4 years 11 months of age. Micro-ethnographic methods were used to analyze the dynamics and development of selected communicative interactions over this age span of Şfty-six months. The original pool of video recordings contained 213 scenes. As a result of video viewing and editing, Akiko’s communication development was found to follow expected patterns of development as described by other child language researchers of children with normal hearing. There were seven demarcations that represent Akiko’s communication and spoken language development: 1 perlocutionary, 2 transition of perlocutionary to illocutionary, 3 illocutionary, 4 transition of illocutionary to locutionary, 5 locutionary, 6 dialogue, and 7 narrative

    This study aimed to determine the impact of cochlear implantation on speech understanding in noise, subjective perception of hearing, and tinnitus perception of adult patients with unilateral severe to profound hearing loss and to investigate whether duration of deafness and age at implantation would influence the outcomes. In addition, this article describes the auditory training protocol used for unilaterally deaf patients. This is a prospective study of subjects undergoing cochlear implantation for unilateral deafness with or without associated tinnitus. Speech perception in noise was tested using the Bamford-Kowal-Bench speech-in-noise test presented at 65 dB SPL. The Speech, Spatial, and Qualities of Hearing Scale and the Abbreviated Profile of Hearing Aid Benefit were used to evaluate the subjective perception of hearing with a cochlear implant and quality of life. Tinnitus disturbance was measured using the Tinnitus Reaction Questionnaire. Data were collected before cochlear implantation and 3, 6, 12, and 24 months after implantation. Twenty-eight postlingual unilaterally deaf adults with or without tinnitus were implanted. There was a significant improvement in speech perception in noise across time in all spatial configurations. There was an overall significant improvement on the subjective perception of hearing and quality of life. Tinnitus disturbance reduced significantly across time. Age at implantation and duration of deafness did not influence the outcomes significantly. Cochlear implantation provided significant improvement in speech understanding in challenging situations, subjective perception of hearing performance, and quality of life. Cochlear implantation also resulted in reduced tinnitus disturbance. Age at implantation and duration of deafness did not seem to influence the outcomes.

    Full Text Available Background: Reading is known as one of the most important learning tools. Research results consistently have shown that even a mild hearing impairment could affect the reading skills. Due to the reported differences in reading comprehension skills between hearing impaired students and their normal hearing peers, this research was conducted to compare the differences between the two groups. The other aim was to find any changes in the reading ability of hearing impaired group during elementary school. Methods: This study is a cross-sectional (descriptive–analytic one in which reading comprehension ability of 91 students with severe and profound hearing impairment (33 girls and 58 boys from 2nd up to 5th grade of exceptional schools were compared with 50 2nd grade normal hearing students in Ahvaz, Iran. The first section of Diagnostic Reading Test (Shirazi – Nilipour, 2004 was used in this study. Then the mean reading scores of hearing impaired students in each grade was compared with control group using SPSS 13 with Mann Whitney test. Results: There was a significant difference between average scores of hearing impaired students (boys and girls in 2nd to 5th grade with normal hearing students of 2nd grade (P<0.001. Reading comprehension scores of students with hearing impairment in higher grades had improved slightly, but it was still lower than that of the normal hearing students in the 2nd grade. Conclusion: It appears that reading comprehension skill of students with significant hearing impairment near the end of elementary school years becomes weaker than normal hearing students in the second grade. Therefore, it is essential to find and resolve the underlying reasons of this condition by all professionals who work in the field of education and rehabilitation of these students.

    Full Text Available Background: Although spermatozoa delivers its RNA to oocytes at fertilization, its biologicalrole is not well characterized. Our purpose was to identify the genes differentially and exclusivelyexpressed in sperm samples both before and after the swim-up process in control donors andinfertile males with the purpose to identify their functional significance in male fertility.Materials and Methods: This was a nested case-control study. Ten sperm samples were obtainedfrom infertile patients [n=5 (two aliquots each from five samples; one before the swim-upprocess and one after] and donors [n=5 (two aliquots from five samples, one before the swim-upprocess and one after]. Oligonucleotide microarrays were employed to study the genome-wideexpression of pooled samples from infertile patients vs. donors. A total of four microarrays wereperfomed: two with sperm sample aliquots before swim-up and two with sperm samples aliquotsafter swim-up, from both the case and control groups. The results were evaluated to detect whichgenes expressed differentially [fold change (FC>5 and p<0.05] and which genes were exclusiveto each of the groups, both before and after swim-up.Results: Profound differences were detected between the fresh sperm samples of donors vs.infertile patients with respect to both differentially and exclusively expressed genes. Neverthelessthese differences seemed to decrease after the swim-up selection process.Conclusion: There are important differences between the expression profiles of sperm samplesof fertile donors vs. infertile patients who require assisted reproduction techniques (ART. Thesedifferences are potential forecasters of fertility success, although their reliability needs to beexplored further.

    Evidence supports the protective role of nonsteroidal anti-inflammatory drugs (NSAID) and statins against colon cancer. Experiments were designed to evaluate the efficacies atorvastatin and NSAIDs administered individually and in combination against colon tumor formation. F344 rats were fed AIN-76A diet, and colon tumors were induced with azoxymethane. One week after the second azoxymethane treatment, groups of rats were fed diets containing atorvastatin (200 ppm), sulindac (100 ppm), naproxen (150 ppm), or their combinations with low-dose atorvastatin (100 ppm) for 45 weeks. Administration of atorvastatin at 200 ppm significantly suppressed both adenocarcinoma incidence (52% reduction, P = 0.005) and multiplicity (58% reduction, P = 0.008). Most importantly, colon tumor multiplicities were profoundly decreased (80%-85% reduction, P < 0.0001) when given low-dose atorvastatin with either sulindac or naproxen. Also, a significant inhibition of colon tumor incidence was observed when given a low-dose atorvastatin with either sulindac (P = 0.001) or naproxen (P = 0.0005). Proliferation markers, proliferating cell nuclear antigen, cyclin D1, and β-catenin in tumors of rats exposed to sulindac, naproxen, atorvastatin, and/or combinations showed a significant suppression. Importantly, colon adenocarcinomas from atorvastatin and NSAIDs fed animals showed reduced key inflammatory markers, inducible nitric oxide synthase and COX-2, phospho-p65, as well as inflammatory cytokines, TNF-α, interleukin (IL)-1β, and IL-4. Overall, this is the first report on the combination treatment using low-dose atorvastatin with either low-dose sulindac or naproxen, which greatly suppress the colon adenocarcinoma incidence and multiplicity. Our results suggest that low-dose atorvastatin with sulindac or naproxen might potentially be useful combinations for colon cancer prevention in humans.

    Participation is known to be of great importance for children's development and emotional well-being as well as for their families. In the International Classification of Functioning, Disability and Health - Children and Youth version participation is defined as a person's 'involvement in a life situation'. Engagement is closely related to involvement and can be seen as expressions of involvement or degree of involvement within a situation. This study focuses on children's engagement in family activities; one group of families with a child with profound intellectual and multiple disabilities (PIMD) and one group of families with children with typical development (TD) were compared. A descriptive study using questionnaires. Analyses were mainly performed by using Mann-Whitney U-test and Spearman's rank correlation test. Engagement in family activities differed in the two groups of children. The children with PIMD had a lower level of engagement in most family activities even though the activities that engaged the children to a higher or lesser extent were the same in both groups. Child engagement was found to correlate with family characteristics mostly in the children with TD and in the children with PIMD only negative correlations occurred. In the children with PIMD child engagement correlated with cognition in a high number of listed family activities and the children had a low engagement in routines in spite of these being frequently occurring activities. Level of engagement in family activities in the group of children with PIMD was lower compared with that in the group of children with TD. Families with a child with PIMD spend much time and effort to adapt family living patterns to the child's functioning. © 2013 John Wiley & Sons Ltd.

    Hypertension and mortality is aggravated by nitric oxide inhibition with N(G)-nitro-L-arginine methyl ester (L-NAME) in spontaneously hypertensive rats (SHRs) but not in Munich Wistar Frömter (MWF) rats. MWF rats carry major albuminuria quantitative trait loci on rat chromosome (RNO) 6 and RNO8; susceptibility of SHRs to L-NAME is enhanced by transfer of RNO6 from MWF rats into the SHR background. Here, we tested whether the sensitivity to L-NAME in SHRs is affected by transfer of RNO8 from MWF rats in consomic SHR-8(MWF) rats. In study 1, we analyzed survival in male SHR and SHR-8(MWF) rats in response to 18 weeks of treatment with either normal drinking water (vehicle-treated) or water containing 20mg/L L-NAME. In study 2, we analyzed blood pressure and renal damage in both strains in response to 6 weeks of treatment with L-NAME compared with vehicle-treated groups. In study 1, starting after 6 weeks of treatment with L-NAME, mortality reached 90% in SHRs in contrast with the group of L-NAME treated SHR-8(MWF) rats (P rats survived similar to vehicle-treated rats. In study 2, L-NAME resulted in a more pronounced increase in mean arterial blood pressures in SHRs compared with SHR-8(MWF) rats (216 ± 6 vs. 180 ± 11 mm Hg; P rats after L-NAME treatment (P < 0.05), whereas albuminuria was not different between strains. The blood pressure increase and impaired survival of SHRs in response to nitric oxide inhibition is profoundly influenced by genes on RNO8.

    Although a number of studies have assessed the effects of geological and climatic changes on species distributions in East Asian, we still have limited knowledge of how these changes have impacted avian species in south-western and southern China. Here, we aim to study paleo-climatic effects on an East Asian bird, two subspecies of black-throated tit (A. c. talifuensis–concinnus) with the combined analysis of phylogeography and Ecological Niche Models (ENMs). We sequenced three mitochondrial DNA markers from 32 populations (203 individuals) and used phylogenetic inferences to reconstruct the intra-specific relationships among haplotypes. Population genetic analyses were undertaken to gain insight into the demographic history of these populations. We used ENMs to predict the distribution of target species during three periods; last inter-glacial (LIG), last glacial maximum (LGM) and present. We found three highly supported, monophyletic MtDNA lineages and different historical demography among lineages in A. c. talifuensis–concinnus. These lineages formed a narrowly circumscribed intra-specific contact zone. The estimated times of lineage divergences were about 2.4 Ma and 0.32 Ma respectively. ENMs predictions were similar between present and LGM but substantially reduced during LIG. ENMs reconstructions and molecular dating suggest that Pleistocene climate changes had triggered and shaped the genetic structure of black-throated tit. Interestingly, in contrast to profound impacts of other glacial cycles, ENMs and phylogeographic analysis suggest that LGM had limited effect on these two subspecies. ENMs also suggest that Pleistocene climatic oscillations enabled the formation of the contact zone and thus support the refuge theory. PMID:22195047

    The multiple and complex disabilities of persons with profound intellectual and multiple disabilities (PIMD) form a barrier for peer interactions and peer-directed behaviours. In this study, we further explore the nature of peer-directed behaviours in persons with PIMD and its relationship with social scaffolding behaviour of direct support workers (DSWs). Fourteen dyads of children with PIMD, who knew each other for at least 12 months, participated. They were sitting in close proximity while they were filmed with and without the presence of the DSW. Video recordings were coded continuously making use of observation schemes for the peer-directed behaviours of the children and the peer interaction influencing behaviours of the DSW. Significantly more singular peer-directed behaviour (without DSW: 18.00%; with DSW: 3.81%) was observed than multiple peer-directed behaviour (without DSW: 4.01%; with DSW: 0.52%). The amount of time the singular and multiple peer-directed behaviours were observed was significantly lower in the presence of a DSW. When the DSW shows peer interaction influencing behaviour, it was mostly social scaffolding behaviour (2.17%). The conditional probability of observing social scaffolding behaviour in the 10 s following on singular peer-directed behaviour was 0.02 with a Yule's Q of 0.04 and following on multiple peer-directed behaviour 0.04 with a Yule's Q of 0.33. The way in which peer interactions in children with PIMD are defined could have an impact on the amount of observed peer-directed behaviours and on the effect of the social scaffolding behaviours presented by DSW. © 2015 John Wiley & Sons Ltd.

    Each addictive disorder has specific characteristics. It is essential to consider them in order to improve the treatment. However, the combination of behavioral addictions and substance use disorders is valid, as showed by the next version of the DSM. During the treatment, it is important to evaluate cross, but also longitudinal, considering the current problematic behavior, but also the problematic behaviors that occurred in the past and that may occur in the future. There is indeed a significant risk of switching addiction. The relapse prevention must consider this risk and be inclusive. Copyright © 2012. Published by Elsevier Masson SAS.

    According to situationism in psychology, behavior is primarily influenced by external situational factors rather than internal traits or motivations such as virtues. Environmental ethicists wish to promote pro-environmental behaviors capable of providing adequate protection for the environment......, but situationist critiques suggest that character traits, and environmental virtues, are not as behaviorally robust as is typically supposed. Their views present a dilemma. Because ethicists cannot rely on virtues to produce pro-environmental behaviors, the only real way of salvaging environmental virtue theory...... is to reject or at least minimize the requirement that environmental ethics must provide protection and assistance to the environment. Virtue theory is often favored by environmentalists precisely because it does matter what one's reasons are for acting, even if one's actions are ineffective at producing...

    1977-12-01

    The energy crisis is approached as a social and psychological problem with solutions based on an understanding of principles of attitude and behavior change. Propaganda calling for voluntary energy conservation has had little effect, and incentive systems present several serious drawbacks. The author believes that the ideal role of both incentives and persuasion is to influence the behavior of groups who in turn would maintain individual behavior and attitudes by social pressure. Thus a program of incentives and education directed at groups of people may effectively increase conservation and change related attitudes without increasing reactance. The author presents 2 strategies to cope with the energy problem: one relies strongly on government action, combining appeal to national feelings and a threat to future coercion to change attitudes and behavior; the other uses incentives to communities for conservation and development of renewable energy resources.

    Full Text Available This paper discuss some general principles of behavioral finance Behavioral finance is the dynamic and promising field of research that mergers concepts from financial economics and cognitive psychology in attempt to better understand systematic biases in decision-making process of financial agents. While the standard academic finance emphasizes theories such as modern portfolio theory and the efficient market hypothesis, the behavioral finance investigates the psychological and sociological issues that impact the decision-making process of individuals, groups and organizations. Most of the research behind behavioral finance has been empirical in nature, concentrating on what people do and why. The research has shown that people do not always act rationally, nor they fully utilise all information available to them.

    2009-07-01

    The resurgence of interest in collective behavior is in large part due to tools recently made available for conducting laboratory experiments on groups, statistical methods for analyzing large data sets reflecting social interactions, the rapid growth of a diverse variety of online self-organized collectives, and computational modeling methods for understanding both universal and scenario-specific social patterns. We consider case studies of collective behavior along four attributes: the primary motivation of individuals within the group, kinds of interactions among individuals, typical dynamics that result from these interactions, and characteristic outcomes at the group level. With this framework, we compare the collective patterns of noninteracting decision makers, bee swarms, groups forming paths in physical and abstract spaces, sports teams, cooperation and competition for resource usage, and the spread and extension of innovations in an online community. Some critical issues surrounding collective behavior are then reviewed, including the questions of "Does group behavior always reduce to individual behavior?"Is 'group cognition' possible?" and "What is the value of formal modeling for understanding group behavior?"

    Cochlear implantation (CI) in subjects with unilateral profound sensorineural hearing loss was investigated. The authors of the present study demonstrated the binaural auditory outcomes in a 12- and 36-month prospective cohort outcome study. The present study aimed to do a long-term (LT) evaluation of the auditory outcomes in an analogous study group. LT evaluation was derived from 12 single-sided deaf (SSD) CI recipients and from 11 CI recipients with asymmetric hearing loss (AHL). A structured interview was conducted with each subjects. Speech perception in noise and sound localization were assessed in a CIOFF and in a CION condition. Four binaural effects were calculated: summation effect (S0N0), squelch effect (S0NCI), combined head shadow effect (SCIN0), and spatial release from masking (SRM). At the LT evaluation, the contribution of a CI or a bone conduction device on speech perception in noise was investigated in two challenging spatial configurations in the SSD group. All (23/23) subjects wore their CI 7 days a week at LT follow-up evaluation, which ranged from 3 to 10 years after implantation. In the SSD group, a significant combined head shadow effect of 3.17 dB and an SRM benefit of 4.33 dB were found. In the AHL group, on the other hand, the summation effect (2.00 dB), the squelch effect (2.67 dB), the combined head shadow effect (3.67 dB), and SRM benefit (2.00 dB) were significant at LT testing. In both the spatial challenging configurations, the speech in noise results was significantly worse in the condition with the bone conduction device compared with the unaided condition. No negative effect was found for the CION condition. A significant benefit in the CION condition was found for sound localization compared with the CIOFF condition in the SSD group and in the AHL group. All subjects wore their CI 7 days a week at LT follow-up evaluation. The presence of binaural effects has been demonstrated with speech in noise testing, sound localization

    Recent literature has suggested that relaxation activities can reduce the challenging behaviours of people with intellectual disabilities, particularly in severe and profound grades, due to the counteractive effect of muscle relaxation on emotional frustration or psychological distress. Despite having inconclusive evidence, multisensory environment (MSE) and massage therapy (MT) are the commonly used approaches to relaxation among these people. However, these two approaches have not yet practised or tested in combination for reducing these people's challenging behaviours. A preliminary clinical efficacy trial was conducted to evaluate the effects of MT, MSE and their combined use for residents with intellectual disabilities in a long-term care facility on reducing their challenging behaviours. Eligible residents were recruited and randomly assigned to one of the four study groups (n = 11-12 per group), that is, MT in MSE, MSE alone, MT alone or usual care, for a 10-week intervention after a 1-month washout period. Outcome measures, including the Behaviour Problem Inventory, pulse and respiration rates, Behaviour Checklist and Alertness Observation Checklist, were assessed at recruitment and immediately following the interventions. A total of 42 participants (17 men and 25 women) completed the study. There were no significant differences in frequency and severity of challenging behaviours and most of the outcome measures between the four groups at post-test. Nevertheless, there were statistical significant differences on the active and inactive state (Alertness Observation Checklist) between the three treatment and control groups. Many participants in the three treatment groups changed from an active to inactive state (i.e. reduced activity levels) throughout the interventions, especially the MT in MSE. Such inactivity might suggest the participants' brief exhaustion followed by a period of alertness during the treatment activities. But their attention span and

    Hoffmann, Kira

    The objective of this dissertation is to investigate determinants and consequences of asymmetric cost behavior. Asymmetric cost behavior arises if the change in costs is different for increases in activity compared to equivalent decreases in activity. In this case, costs are termed “sticky......” if the change is less when activity falls than when activity rises, whereas costs are termed “anti-sticky” if the change is more when activity falls than when activity rises. Understanding such cost behavior is especially relevant for decision-makers and financial analysts that rely on accurate cost information...... to facilitate resource planning and earnings forecasting. As such, this dissertation relates to the topic of firm profitability and the interpretation of cost variability. The dissertation consists of three parts that are written in the form of separate academic papers. The following section briefly summarizes...

    Full Text Available Although the field of modern finance has progressed impressively, it is still hard to explain on a scientific basis why people behave nonrationally when dealing with money. The classic finance assumes people rationalize and optimize their financial decisions. Behavioral Finance adds the importance of what investors should do and complements the mantra of classic finance with what people actually do, in terms of economic decisions. The new field of Neuroeconomy investigates the subtle and profound interactions within the human brain when faced with uncertainties of an economic decision. The most basic psychological traits of human being (fear, anger, greed and altruism stamp an indelible mark on our decisions about money. The intellect (understanding a situation, reason (long term consequences of the contemplated action and emotion (the judge of the course of action are all intercorrelated resorts behind human decision making.

    During and after an erosive challenge, behavioral factors play a role in modifying the extent of erosive tooth wear. The manner that dietary acids are introduced into the mouth (gulping, sipping, use of a straw) will affect how long the teeth are in contact with the erosive challenge. The frequency and duration of exposure to an erosive agent is of paramount importance. Night-time exposure (e.g. baby bottle-feeding) to erosive agents may be particularly destructive because of the absence of salivary flow. Health-conscious individuals tend to ingest acidic drinks and juices more frequently and tend to have higher than average oral hygiene. While good oral hygiene is of proven value in the prevention of periodontal disease and dental caries, frequent toothbrushing with abrasive oral hygiene products may enhance erosive tooth wear. Unhealthy lifestyles such as consumption of designer drugs, alcopops and alcohol abuse are other important behavioral factors.

    2014-01-01

    We re-evaluate the theory, experimental design and econometrics behind claims that individuals exhibit non-constant discounting behavior. Theory points to the importance of controlling for the non-linearity of the utility function of individuals, since the discount rate is defined over time......-dated utility flows and not flows of money. It also points to a menagerie of functional forms to characterize different types of non-constant discounting behavior. The implied experimental design calls for individuals to undertake several tasks to allow us to identify these models, and to several treatments...... such as multiple horizons and the effect of allowing for a front end delay on earlier payments. The implied econometrics calls for structural estimation of the theoretical models, allowing for joint estimation of utility functions and discounting functions.

  1. Behavioral epigenetics.

    2017-01-01

    Why do we grow up to have the traits we do? Most 20th century scientists answered this question by referring only to our genes and our environments. But recent discoveries in the emerging field of behavioral epigenetics have revealed factors at the interface between genes and environments that also play crucial roles in development. These factors affect how genes work; scientists now know that what matters as much as which genes you have (and what environments you encounter) is how your genes are affected by their contexts. The discovery that what our genes do depends in part on our experiences has shed light on how Nature and Nurture interact at the molecular level inside of our bodies. Data emerging from the world's behavioral epigenetics laboratories support the idea that a person's genes alone cannot determine if, for example, he or she will end up shy, suffering from cardiovascular disease, or extremely smart. Among the environmental factors that can influence genetic activity are parenting styles, diets, and social statuses. In addition to influencing how doctors treat diseases, discoveries about behavioral epigenetics are likely to alter how biologists think about evolution, because some epigenetic effects of experience appear to be transmissible from generation to generation. This domain of research will likely change how we think about the origins of human nature.

    Full Text Available Counseling training in graduate programs continues to be underrepresented. If parental queries are not addressed adequately, they keep visiting one doctor after another. Objective. The aim of the study is to identify maternal needs of children with hearing impairment at two stages of habilitation, that is, just after diagnosis (group I and after receiving 1 to 3 years of language therapy (group II. Methods. Two groups of mothers were asked to speak their queries about aural habilitation of their children. Queries were recorded, summarized, and categorized as per their priorities. Results. Group I mothers wanted to know about how the child would learn to listen and speak (45%, causes of hearing loss (33.7%, understanding the ear and hearing (10.2%, understanding the audiogram (7%, and coping with emotional aspects of hearing loss (5%, while group II parents had priorities concerning speech development (24.5% followed by child independence and employment (17.3%, schooling (15.6%, problem behaviors (11%, amplification device (9.4%, duration of therapy (8%, future of the child (8%, and questions about how can my child get adjusted to the “normal” world (6%. Conclusions. Culture- and language-specific materials to explain these issues need to be developed.

    The development of language and communication may play an important role in the emergence of behavioral problems in young children, but they are rarely included in predictive models of behavioral development. In this study, cross-sectional relationships between language, attention, and behavior problems were examined using parent report, videotaped observations, and performance measures in a sample of 116 severely and profoundly deaf and 69 normally hearing children ages 1.5 to 5 years. Secondary analyses were performed on data collected as part of the Childhood Development After Cochlear Implantation Study, funded by the National Institutes of Health. Hearing-impaired children showed more language, attention, and behavioral difficulties, and spent less time communicating with their parents than normally hearing children. Structural equation modeling indicated there were significant relationships between language, attention, and child behavior problems. Language was associated with behavior problems both directly and indirectly through effects on attention. Amount of parent-child communication was not related to behavior problems.

    Cervical cancer is the fourth common cancer in women resulting worldwide in 266,000 deaths per year. Belonging to the carcinomas, new insights into cervical cancer biology may also have great implications for finding new treatment strategies for other kinds of epithelial cancers. Although the transcription factor NF-κB is known as a key player in tumor formation, the relevance of its particular subunits is still underestimated. Here, we applied CRISPR/Cas9n-mediated genome editing to successfully knockout the NF-κB subunit c-REL in HeLa Kyoto cells as a model system for cervical cancers. We successfully generated a homozygous deletion in the c-REL gene, which we validated using sequencing, qPCR, immunocytochemistry, western blot analysis, EMSA and analysis of off-target effects. On the functional level, we observed the deletion of c-REL to result in a significantly decreased cell proliferation in comparison to wildtype (wt) without affecting apoptosis. The impaired proliferative behavior of c-REL-/- cells was accompanied by a strongly decreased amount of the H2B protein as well as a significant delay in the prometaphase of mitosis compared to c-REL+/+ HeLa Kyoto cells. c-REL-/- cells further showed significantly decreased expression levels of c-REL target genes in comparison to wt. In accordance to our proliferation data, we observed the c-REL knockout to result in a significantly increased resistance against the chemotherapeutic agents 5-Fluoro-2’-deoxyuridine (5-FUDR) and cisplatin. In summary, our findings emphasize the importance of c-REL signaling in a cellular model of cervical cancer with direct clinical implications for the development of new treatment strategies.

    2009-01-01

    It is human nature to overestimate how rational we are, both in general and even when we are trying to be. Such irrationality is not random, and the search for and explanation of patterns of fuzzy thinking is the basis for a new academic discipline known as behavioral economics. Examples are given of some of the best understood of our foibles, including prospect theory, framing, anchoring, salience, confirmation bias, superstition, and ownership. Humans have two cognitive systems: one conscious, deliberate, slow, and rational; the other fast, pattern-based, emotionally tinged, and intuitive. Each is subject to its own kind of error. In the case of rational thought, we tend to exaggerate our capacity; for intuition, we fail to train it or recognize contexts where it is inappropriate. Humans are especially poor at estimating probabilities, or even understanding what they are. It is a common human failing to reason backwards from random outcomes that are favorable to beliefs about our power to predict the future. Five suggestions are offered for thinking within our means.

    The level of resident's adaptive behaviour and staff facilitative practices are key sources of variation in outcomes for residents in community-based residential services. The higher the resident support needs the poorer their outcome. Although substantial investment has been made in values-based training for staff, their attitudes and the impact of these on practice is largely unexplored. The first study used ethnographic and action research methods to examine the daily lives of 25 residents with severe and profound intellectual disabilities (ID), who lived in five small group homes, and the attitudes of the staff supporting them. Thematic analysis of the data led to a proposition that although staff accept principles of inclusion, choice and participation for people with ID in general, they do not consider it feasible to apply these to the people with severe and profound ID to whom they provide support. The findings from a second study that used a group comparison design and administered a short questionnaire about staff attitudes to 144 direct-care staff and first-line managers working in disability services confirmed this hypothesis. The study suggests more focused attention is needed to staff understanding the values embedded in current policies and their application to people with more severe disabilities.

    Social factors influence drug abuse. Conversely, drugs of abuse alter social behavior. This is especially pertinent during post-weaning development, when there are profound changes in the social repertoire, and the sensitivity to the positive and negative effects of drugs of abuse is altered. This study aimed to provide an overview of our current understanding of the interaction between drugs of abuse and juvenile/adolescent social behavior. We first provide evidence that a characteristic form of juvenile and adolescent social behavior, i.e., social play behavior, has reinforcing properties and is affected by drugs of abuse. Next, social risk factors for drug use and addiction are described, including antisocial personality traits and early social insults. Last, we discuss research that investigates social influences on drug use, as well as the consequences of perinatal drug exposure on later social interactions. Social play behavior is highly rewarding in laboratory animals, and it is affected by low doses of opioids, cannabinoids, ethanol, nicotine, and psychostimulants. In humans, antisocial personality traits, most prominently in the form of conduct disorder, are a prominent risk factor for drug addiction. Preclinical studies have consistently shown altered sensitivity to drugs as a result of social isolation during post-weaning development. The social environment of an individual has a profound, but complex, influence on drug use, and perinatal drug exposure markedly alters later social interactions. The studies reviewed here provide a framework to understand the interaction between drugs of abuse and adolescent social interaction, at the preclinical and the clinical level.

  11. Common and novel transcriptional routes to behavioral maturation in worker and male honey bees.

    2012-04-01

    Worker honey bees (Apis mellifera) undergo a process of behavioral maturation leading to their transition from in-hive tasks to foraging--a process which is associated with profound transcriptional changes in the brain. Changes in brain gene expression observed during worker behavioral maturation could represent either a derived program underlying division of labor or a general program unrelated to sociality. Male bees (drones) undergo a process of behavioral maturation associated with the onset of mating flights, but do not partake in division of labor. Drones thus provide an excellent reference point for polarizing transcriptional changes associated with behavioral maturation in honey bees. We assayed the brain transcriptomes of adult drones and workers to compare and contrast differences associated with behavioral maturation in the two sexes. Both behavioral maturation and sex were associated with changes in expression of thousands of genes in the brain. Many genes involved in neuronal development, behavior, and the biosynthesis of neurotransmitters regulating the perception of reward showed sex-biased gene expression. Furthermore, most of the transcriptional changes associated with behavioral maturation were common to drones and workers, consistent with common genetic and physiological regulation. Our study suggests that there is a common behavioral maturation program that has been co-opted and modified to yield the different behavioral and cognitive phenotypes of worker and drone bees. © 2011 The Authors.

  12. Odor-guided behavior in mammals.

    Doty, R L

    1986-03-15

    The odor-guided behaviors selected for presentation in this paper encompass the major areas of animal behavior, and illustrate the important principal that complex relations exist between odor-guided behaviors, hormonal state, and experiential factors. Clearly, experiences with odors at several life stages results in profound influences upon later behaviors, including those related to eating, mating, fighting, and nesting. Interestingly, only brief social encounters are needed in rats to induce such phenomena as ultrasonic calling to conspecific estrous females or their odors, preferences for estrous over non-estrous odors, and the short-term modification of feeding behaviors. Although the mechanisms behind these intriguing phenomena are poorly understood, it is noteworthy that rats can learn relatively complex concepts on the basis of odors, rivaling even the ability of our own species to learn analogous tasks by visual cues. Despite the fact that close relationships can be demonstrated between odor-guided behaviors and variables such as endocrine state and sexual experience, caution is warranted in assuming that simple causal relations exist between such variables. In normally cycling women, for example, the correlation between olfactory sensitivity and plasma levels of estradiol during the menstrual cycle is relatively high; however, attenuation of the cyclical estradiol fluctuations by oral contraceptives does not eliminate the olfactory fluctuations, suggesting the relation is not causal. In house mice, social experience can override hormonal factors in their odor-guided urine marking and submissive behaviors. Thus, even though androgen titer usually correlates with such measures, a mouse made subordinant in a social encounter will not exhibit scent marking even when its circulating testosterone is maintained at a high level by a silastic implant. Further reason for caution comes from studies that suggest olfactory input influences the endocrine systems of

    Full Text Available The intensification of the production system in the poultry industry and the vertical integration of the poultry agribusiness have brought profound changes in the physical and social environment of domestic fowls in comparison to their ancestors and have modified the expression of aggression and submission. The present review has covered the studies focusing on the different aspects linked to aggressiveness in the genus Gallus. The evaluated studies have shown that aggressiveness and subordination are complex behavioral expressions that involve genetic differences between breeds, strains and individuals, and differences in the cerebral development during growth, in the hormonal metabolism, in the rearing conditions of individuals, including feed restriction, density, housing type (litter or cage, influence of the opposite sex during the growth period, existence of hostile stimuli (pain and frustration, ability to recognize individuals and social learning. The utilization of fighting birds as experimental material in the study of mechanisms that have influence on the manifestation of aggressiveness in the genus Gallus might comparatively help to elucidate important biological aspects of such behavior.

    The ability to predict regular events can be adaptive for nonhuman animals living in an otherwise unpredictable environment. Animals may exhibit behavioral changes preceding a predictable event; such changes reflect anticipatory behavior. Anticipatory behavior is broadly defined as a goal-directed increase in activity preceding a predictable event and can be useful for assessing well being in animals in captivity. Anticipation may look different in different animals, however, necessitating methods to generate and study anticipatory behaviors across species. This article includes a proposed method for generating and describing anticipatory behavior in zoos using behavioral conditioning. The article also includes discussion of case studies of the proposed method with 2 animals at the San Francisco Zoo: a silverback gorilla (Gorilla gorilla gorilla) and a red panda (Ailurus fulgens). The study evidence supports anticipation in both animals. As behavioral conditioning can be used with many animals, the proposed method provides a practical approach for using anticipatory behavior to assess animal well being in zoos.

    2015-05-01

    Full Text Available The repertoire of socio-sexual and sexual behaviors of cetaceans is relatively unknown. The purpose of the current study was to advance the existing knowledge of socio-sexual behavior of beluga whales through the development of a behavioral catalog that lists the full repertoire of sexual and socio-sexual behaviors. A behavioral catalog was developed initially from 800 hours of observations, collected across a 7-year period from 11 belugas ranging in age (birth to 30+ years, sex, and social groupings. Using this behavioral catalog, observations of eight additional belugas housed between two other facilities were coded for socio-sexual and sexual behaviors. Socio-sexual and sexual behaviors of belugas were similar across all three facilities. Socio-sexual and sexual behaviors involved sequenced behaviors, had lateralized components, and were often subtle in nature. Some of these behaviors overlapped with potentially aggressive actions but showed distinct differences in their form, or topography. Complexity and duration of socio-sexual interactions varied depending on the age and sex of the participating belugas. The development of a complete behavioral catalog, or ethogram, of the socio-sexual and sexual behaviors has profound influences on understanding the mechanisms involved for successful reproduction, a problem that several groups of belugas in their natural habitat are currently facing.

    Full Text Available Behaviorism has argued that behavior is the Psyche and the subject matter of psychology. Although, some scientists had done empirical work with objective methods before 1913, the year in which John B. Watson published his manifesto, he was the first one to attempt a systematization of behavior as the Psyche, that is, as psychology’s subject matter. In this text, I outline Watson’s notion of behavior to compare it with two other forms of behaviorism: Skinner’s radical behaviorism and molar behaviorism. The purpose of the paper is to illustrate how the concept of behavior has been and is changing.

    Although the study of helping behavior has revolutionized the field of behavioral ecology, scientific examination of rescue behavior remains extremely rare, except perhaps in ants, having been described as early as 1874. Nonetheless, recent work in our laboratories has revealed several new patterns of rescue behavior that appear to be much more complex than previously studied forms. This precisely-directed rescue behavior bears a remarkable resemblance to what has been labeled empathy in rats, and thus raises numerous philosophical and theoretical questions: How should rescue behavior (or empathy) be defined? What distinguishes rescue from other forms of altruism? In what ways is rescue behavior in ants different from, and similar to, rescue in other non-human animals? What selection pressures dictate its appearance? In this paper, we review our own experimental studies of rescue in both laboratory and field, which, taken together, begin to reveal some of the behavioral ecological conditions that likely have given rise to rescue behavior in ants. Against this background, we also address important theoretical questions involving rescue, including those outlined above. In this way, we hope not only to encourage further experimental analysis of rescue behavior, but also to highlight important similarities and differences in very distant taxa.

    Background Behavioral assessment of mutant mouse models and novel candidate drugs is a slow and labor intensive process. This limitation produces a significant impediment to CNS drug discovery. New method By combining video and vibration analysis we created an automated system that provides the most detailed description of mouse behavior available. Our system (The Behavioral Spectrometer) allowed for the rapid assessment of behavioral abnormalities in the BTBR model of Autism, the restraint model of stress and the irritant model of inflammatory pain. Results We found that each model produced a unique alteration of the spectrum of behavior emitted by the mice. BTBR mice engaged in more grooming and less rearing behaviors. Prior restraint stress produced dramatic increases in grooming activity at the expense of locomotor behavior. Pain produced profound decreases in emitted behavior that were reversible with analgesic treatment. Comparison with existing method(s) We evaluated our system through a direct comparison on the same subjects with the current “gold standard” of human observation of video recordings. Using the same mice evaluated over the same range of behaviors, the Behavioral Spectrometer produced a quantitative categorization of behavior that was highly correlated with the scores produced by trained human observers (r=0.97). Conclusions Our results show that this new system is a highly valid and sensitive method to characterize behavioral effects in mice. As a fully automated and easily scalable instrument the Behavioral Spectrometer represents a high-throughput behavioral tool that reduces the time and labor involved in behavioral research.

    Unilateral paralysis is rarely reported to be primary presentation of severe hypokalemia. We describe a 24-year-old woman who presented to the emergency department with sudden onset of right-sided weakness. Neurologic examination revealed diminished muscle strength and tendon reflexes over the right limbs. Computed tomography of the brain showed no organic brain lesion. However, laboratory data showed hypokalemia (K+ 2.0 mmol/L) with metabolic acidosis (HCO3 − 19 mmol/L). She needed a total of 260 mmol K+ to achieve complete recovery of muscle strength at a serum K+ level of 3.2 mmol/L and was proved to have distal renal tubular acidosis. Severe hypokalemia must be kept in mind as a cause of acute unilateral paralysis without organic lesions to avoid unnecessary examination and potentially life-threatening complications.

    Social identities are associated with normative standards for thought and action, profoundly influencing the behavioral choices of individual group members. These social norms provide frameworks for identifying the most appropriate actions in any situation. Given the increasing complexity of the social world, however, individuals are more and more likely to identify strongly with multiple social groups simultaneously. When these groups provide divergent behavioral norms, individuals can experience social identity conflict. The current manuscript examines the nature and consequences of this socially conflicted state, drawing upon advances in our understanding of the neuropsychology of conflict and uncertainty. Identity conflicts are proposed to involve activity in the Behavioral Inhibition System, which in turn produces high levels of anxiety and stress. Building upon this framework, four strategies for resolving identity conflict are reviewed. © 2015 by the Society for Personality and Social Psychology, Inc.

  11. Mechanisms of Odor Coding in Coniferous Bark Beetles: From Neuron to Behavior and Application

    2012-01-01

    Full Text Available Coniferous bark beetles (Coleoptera: Curculionidae: Scolytinae locate their hosts by means of olfactory signals, such as pheromone, host, and nonhost compounds. Behavioral responses to these volatiles are well documented. However, apart from the olfactory receptor neurons (ORNs detecting pheromones, information on the peripheral olfactory physiology has for a long time been limited. Recently, however, comprehensive studies on the ORNs of the spruce bark beetle, Ips typographus, were conducted. Several new classes of ORNs were described and odor encoding mechanisms were investigated. In particular, links between behavioral responses and ORN responses were established, allowing for a more profound understanding of bark beetle olfaction. This paper reviews the physiology of bark beetle ORNs. Special focus is on I. typographus, for which the available physiological data can be put into a behavioral context. In addition, some recent field studies and possible applications, related to the physiological studies, are summarized and discussed.

    Though the decision to behave immorally is situated within the context of prior immoral behavior, research has provided contradictory insights into this process. In a series of experiments, we demonstrate that the effects of prior immoral behavior depend on how individuals think about, or reflect on, their immoral behavior. In Experiment 1, participants who reflected counterfactually on their prior moral lapses morally disengaged (i.e., rationalized) less than participants who reflected factually. In Experiment 2, participants who reflected counterfactually on their prior moral lapses experienced more guilt than those who reflected factually. Finally, in Experiments 3 and 4, participants who reflected counterfactually lied less on unrelated tasks with real monetary stakes than those who reflected factually. Our studies provide important insights into moral rationalization and moral compensation processes and demonstrate the profound influence of reflection in everyday moral life.

    Full Text Available The structures and behaviors of grain boundaries (GBs have profound effects on the mechanical properties of polycrystalline materials. In this paper, twist GBs in aluminum were investigated with molecular dynamic simulations to reveal their atomic structures, energy and interactions with dislocations. One hundred twenty-six twist GBs were studied, and the energy of all these twist GBs were calculated. The result indicates that and twist GBs have lower energy than twist GBs because of their higher interplanar spacing. In addition, 12 types of twist GBs in aluminum were chosen to explore the deformation behaviors. Low angle twist GBs with high density of network structures can resist greater tension because mutually hindering behaviors between partial dislocations increase the twist GB strength.

    Empathy is an important psychological process that facilitates human communication and interaction. Enhancement of empathy has profound significance in a range of applications. In this paper, we review emerging directions of research on computational analysis of empathy expression and perception as well as empathic interactions, including their simulation. We summarize the work on empathic expression analysis by the targeted signal modalities (e.g., text, audio, and facial expressions). We categorize empathy simulation studies into theory-based emotion space modeling or application-driven user and context modeling. We summarize challenges in computational study of empathy including conceptual framing and understanding of empathy, data availability, appropriate use and validation of machine learning techniques, and behavior signal processing. Finally, we propose a unified view of empathy computation and offer a series of open problems for future research.

    Full Text Available Recently, scholars from a variety of disciplines have begun to investigate passionate love, sexual desire, and sexual behavior. Specifically, they have begun to investigate questions profound questions as: “Why do men and women engage in sexual liaisons?” “Why do they avoid such liaisons?” In this paper, we will review what theorists have learned about the motives that encourage people to engage in (or to avoid sexual encounters, focusing specifically about what is know about the influence of gender, personality, and social context on sexual motives. We will close by speculating about the impact of such differing motives on sexual functioning and the prevalence of STIs and AIDs.

    We aimed to assess parental burden of care, satisfaction with family-centered care, and quality of life (HRQoL) of parents and their hospitalized children with profound intellectual and multiple disabilities (PIMD), and determine the relationship among these factors. A cross-sectional study using printed questionnaires and qualitative questions was undertaken at a Swiss University Children's Hospital. The 117 parents (98 mothers, 19 fathers) studied indicated a substantial impact on burden of care and parental health-related quality of life. Significant correlations with the hospitalized children's well-being were rs = .408 for burden of care and rs -.368 for quality of life. Qualitative results showed parents struggling to safeguard their children and worrying most about the children's well-being. Health professionals need to be aware of parental burden and that the perception of the children's well-being and the parents' efforts determine their support needs. Easing parents' burden and fostering confidence in the hospitalized children's well-being requires coordination of care provided by advanced nurse specialists, with an institutional framework that clarifies parental collaboration. © 2016, Wiley Periodicals, Inc.

    2014-05-28

    Opioids are among the world's oldest known drugs used mostly for pain relief, but recreational use is also widespread. A particularly important problem is opioid exposure in females, as their offspring can also be affected. Adverse intrauterine and postnatal environments can affect offspring development and may lead to various disabilities later in life. It is clear that repetitive painful experiences, such as randomly occurring invasive procedures during neonatal intensive care, can permanently alter neuronal and synaptic organization and therefore later behavior. At the same time, analgesic drugs can also be harmful, inducing neuronal apoptosis or withdrawal symptoms in the neonate and behavioral alterations in adulthood. Hence, risk-benefit ratios should be taken into consideration when pain relief is required during pregnancy or in neonates. Recreational use of opioids can also alter many aspects of life. Intrauterine opioid exposure has many toxic effects, inducing poor pregnancy outcomes due to underdevelopment, but it is believed that later negative consequences are more related to environmental factors such as a chaotic lifestyle and inadequate prenatal care. One of the crucial components is maternal care, which changes profoundly in addicted mothers. In substance-dependent mothers, pre- and postnatal care has special importance, and controlled treatment with a synthetic opioid (e.g., methadone) could be beneficial. We aimed to summarize and compare human and rodent data, as it is important to close the gap between scientific knowledge and societal policies. Special emphasis is given to gender differences in the sensitivity of offspring to perinatal opioid exposure. Copyright © 2014 Elsevier Inc. All rights reserved.

    Social and behavioral research in public health is often intimately tied to profound, but frequently neglected, biological influences from underlying genetic, environmental, and epigenetic events. The dynamic interplay between the life, social, and behavioral sciences often remains underappreciated and underutilized in addressing complex diseases and disorders and in developing effective remediation strategies. Using a case-study format, we present examples as to how the inclusion of genetic, environmental, and epigenetic data can augment social and behavioral health research by expanding the parameters of such studies, adding specificity to phenotypic assessments, and providing additional internal control in comparative studies. We highlight the important roles of gene-environment interactions and epigenetics as sources of phenotypic change and as a bridge between the life and social and behavioral sciences in the development of robust interdisciplinary analyses.

  12. Behavioral Immunity in Insects

    Directory of Open Access Journals (Sweden)

    Thierry Lefèvre

    2012-08-01

    Full Text Available Parasites can dramatically reduce the fitness of their hosts, and natural selection should favor defense mechanisms that can protect hosts against disease. Much work has focused on understanding genetic and physiological immunity against parasites, but hosts can also use behaviors to avoid infection, reduce parasite growth or alleviate disease symptoms. It is increasingly recognized that such behaviors are common in insects, providing strong protection against parasites and parasitoids. We review the current evidence for behavioral immunity in insects, present a framework for investigating such behavior, and emphasize that behavioral immunity may act through indirect rather than direct fitness benefits. We also discuss the implications for host-parasite co-evolution, local adaptation, and the evolution of non-behavioral physiological immune systems. Finally, we argue that the study of behavioral immunity in insects has much to offer for investigations in vertebrates, in which this topic has traditionally been studied.

  13. Analysis of Autopilot Behavior

    Sherry, Lance; Polson, Peter; Feay, Mike; Palmer, Everett; Null, Cynthia H. (Technical Monitor)

    1998-01-01

    Aviation and cognitive science researchers have identified situations in which the pilot's expectations for behavior of autopilot avionics are not matched by the actual behavior of the avionics. These "automation surprises" have been attributed to differences between the pilot's model of the behavior of the avionics and the actual behavior encoded in the avionics software. A formal technique is described for the analysis and measurement of the behavior of the cruise pitch modes of a modern Autopilot. The analysis characterizes the behavior of the Autopilot as situation-action rules. The behavior of the cruise pitch mode logic for a contemporary modern Autopilot was found to include 177 rules, including Level Change (23), Vertical Speed (16), Altitude Capture (50), and Altitude Hold (88). These rules are determined based on the values of 62 inputs. Analysis of the rule-based model also shed light on the factors cited in the literature as contributors to "automation surprises."

    A probable list of causes for the limited acceptance of behaviorism in our society is identified. This is followed by a summary review of the proposed solutions identified in other papers in this special issue of The Behavior Analyst, most of which relate to either better marketing of either the behavior analytic process or the results achieved as a consequence. One paper proposes a more broad conception of behavior analysis. This paper endorses the solutions identified in previous papers and then goes on to propose an even more broad conception of behavior analysis and makes the point that behavior analysis is unlikely to flourish unless behavior analysts understand a good deal more about the cultural and other contextual features of the environments in which they work.

    Parents of children with autism spectrum disorder (ASD) were shown to experience more stress than parents of typically developing peers, although little is known about risk factors predicting stress in this population. The aim of this study was to evaluate parental stress levels and behavioral and emotional problems in a sample of preschool children with ASD as compared to typically developing (TD) peers and to investigate the role of several factors, including the severity of autistic symptoms, adaptive skills, cognitive abilities and behavioral and emotional problems, on parental stress. Results confirmed that parents of children with ASD experience higher stress levels than parents of TD and that children with ASD show more behavioral and emotional problems than controls. Moreover, our results showed that behavioral and emotional problems are strong predictors of parental stress, while stress related to a parent-child dysfunctional relationship was associated with daily living and communication skills as well as cognitive abilities. Findings revealed different behavioral and emotional problems affecting parental stress in ASD and TD samples. No association between the severity of autism symptoms and parental stress was detected. These results suggest that dysfunctional behaviors in preschool children with ASD have a strong impact on parental stress, profoundly affecting the well-being of the entire family. Therefore, strategies aimed at the early detection and management of these behavioral and emotional problems are crucial in order to prevent parental stress and to develop the most appropriate treatment interventions.

    Full Text Available In order to develop a more sustainable society, the wider public will need to increase engagement in pro-environmental behaviors. Psychological research on pro-environmental behaviors has thus far focused on identifying individual factors that promote such behavior, designing interventions based on these factors, and evaluating these interventions. Contextual factors that may also influence behavior at an aggregate level have been largely ignored. In the current study, we test a novel hypothesis--whether simply being in a sustainable building can elicit environmentally sustainable behavior. We find support for our hypothesis: people are significantly more likely to correctly choose the proper disposal bin (garbage, compost, recycling in a building designed with sustainability in mind compared to a building that was not. Questionnaires reveal that these results are not due to self-selection biases. Our study provides empirical support that one's surroundings can have a profound and positive impact on behavior. It also suggests the opportunity for a new line of research that bridges psychology, design, and policy-making in an attempt to understand how the human environment can be designed and used as a subtle yet powerful tool to encourage and achieve aggregate pro-environmental behavior.

    2015-03-01

    An important goal of providing amplification to children with hearing loss is to ensure that hearing aids are adjusted to match targets of prescriptive procedures as closely as possible. The Desired Sensation Level (DSL) v5 and the National Acoustic Laboratories' prescription for nonlinear hearing aids, version 1 (NAL-NL1) procedures are widely used in fitting hearing aids to children. Little is known about hearing aid fitting outcomes for children with severe or profound hearing loss. The purpose of this study was to investigate the prescribed and measured gain of hearing aids fit according to the NAL-NL1 and the DSL v5 procedure for children with moderately severe to profound hearing loss; and to examine the impact of choice of prescription on predicted speech intelligibility and loudness. Participants were fit with Phonak Naida V SP hearing aids according to the NAL-NL1 and DSL v5 procedures. The Speech Intelligibility Index (SII) and estimated loudness were calculated using published models. The sample consisted of 16 children (30 ears) aged between 7 and 17 yr old. The measured hearing aid gains were compared with the prescribed gains at 50 (low), 65 (medium), and 80 dB SPL (high) input levels. The goodness of fit-to-targets was quantified by calculating the average root-mean-square (RMS) error of the measured gain compared with prescriptive gain targets for 0.5, 1, 2, and 4 kHz. The significance of difference between prescriptions for hearing aid gains, SII, and loudness was examined by performing analyses of variance. Correlation analyses were used to examine the relationship between measures. The DSL v5 prescribed significantly higher overall gain than the NAL-NL1 procedure for the same audiograms. For low and medium input levels, the hearing aids of all children fit with NAL-NL1 were within 5 dB RMS of prescribed targets, but 33% (10 ears) deviated from the DSL v5 targets by more than 5 dB RMS on average. For high input level, the hearing aid fittings of

    We focused on over-dose insulin (250 IU/kg i.p.) induced gastric ulcers and then on other disturbances that were concomitantly induced in rats, seizures (eventually fatal), severely damaged neurons in cerebral cortex and hippocampus, hepatomegaly, fatty liver, increased AST, ALT and amylase serum values, breakdown of liver glycogen with profound hypoglycemia and calcification development. Calcium deposits were present in the blood vessel walls, hepatocytes surrounding blood vessels and sometimes even in parenchyma of the liver mainly as linear and only occasionally as granular accumulation. As an antidote after insulin, we applied the stable gastric pentadecapeptide BPC 157 (10 microg/kg) given (i) intraperitoneally or (ii) intragastrically immediately after insulin. Controls received simultaneously an equivolume of saline (5 ml/kg). Those rats that survived till the 180 minutes after over-dose application were further assessed. Interestingly, pentadecapeptide BPC 157, as an antiulcer peptide, may besides stomach ulcer consistently counteract all insulin disturbances and fatal outcome. BPC 157 rats showed no fatal outcome, they were mostly without hypoglycemic seizures with apparently higher blood glucose levels (glycogen was still present in hepatocytes), less liver pathology (i.e., normal liver weight, less fatty liver), decreased ALT, AST and amylase serum values, markedly less damaged neurons in brain and they only occasionally had small gastric lesions. BPC 157 rats exhibited mostly only dot-like calcium presentation. In conclusion, the success of BPC 157 therapy may indicate a likely role of BPC 157 in insulin controlling and BPC 157 may influence one or more causative process(es) after excessive insulin application.

    A Dutch version of the 'Measure of Processes of Care for Service Providers' (MPOC-SP) was developed to determine the extent to which professionals apply the principles of family-centred care in the rehabilitation of children with physical disabilities. However, no data were available on the reliability and construct validity of this instrument when it comes to supporting people with profound intellectual and multiple disabilities (PIMD). This study aimed to validate an adapted version of the Dutch MPOC-SP for assessing the family-centred behaviours of professionals who support this group (MPOC-SP-PIMD). A total of 105 professionals took part in the study. A Mokken scale analysis was conducted to determine whether the instrument satisfied the assumptions of both monotone homogeneity and double monotonicity. Loevinger's scalability coefficient (H) was used for the scalability of the entire scale and of each item separately. Rho was calculated as a measure of the internal consistency of the scales. The analyses resulted in two scales: a nine-item scale interpreted as 'Showing Interpersonal Sensitivity', with H=.39 and rho=.76, and a seven-item scale interpreted as 'Treating People Respectfully', with H=.49 and rho=.78. A validated version of the MPOC-SP-PIMD, suitable for supporting people with PIMD, consists of a subset of two scales from the original Dutch MPOC-SP. This instrument can be used to compare the family-centredness of professionals with parent's expectations and views. This information can be used in practice to match the support to the needs of the parents and family of the child with PIMD. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Anxious individuals infer danger from information about physiological responses, anxiety responses, and safety behaviors. This study investigated whether anxious individuals also infer safety from approach behavior. 325 students rated the danger they perceived in general and spider-relevant scenarios in which information about objective safety versus objective danger, and approach behavior versus no approach behavior, was varied. A high and low spider fearful group was created with a median split on spider fear. Participants with a high fear of spiders, compared to participants with low spider fear, rated spider scenarios with approach behavior as safer than spider scenarios without approach behavior. This effect was similar for objectively dangerous and safe spider scenarios. No behavior as information effects were found for general scenarios. The data were collected in a non-clinical student sample. Spider fearful individuals infer safety from approach behavior in spider-relevant scenarios. For spider fearful individuals, approach behavior may add to the beneficial effects of exposure therapy. Future research is needed to investigate whether patients with anxiety disorders also show a tendency to infer safety from approach behavior. Copyright © 2017 Elsevier Ltd. All rights reserved.

  2. Introduction to behavioral addictions.

    2010-09-01

    Several behaviors, besides psychoactive substance ingestion, produce short-term reward that may engender persistent behavior, despite knowledge of adverse consequences, i.e., diminished control over the behavior. These disorders have historically been conceptualized in several ways. One view posits these disorders as lying along an impulsive-compulsive spectrum, with some classified as impulse control disorders. An alternate, but not mutually exclusive, conceptualization considers the disorders as non-substance or "behavioral" addictions. Inform the discussion on the relationship between psychoactive substance and behavioral addictions. We review data illustrating similarities and differences between impulse control disorders or behavioral addictions and substance addictions. This topic is particularly relevant to the optimal classification of these disorders in the forthcoming fifth edition of the American Psychiatric Association Diagnostic and Statistical Manual of Mental Disorders (DSM-V). Growing evidence suggests that behavioral addictions resemble substance addictions in many domains, including natural history, phenomenology, tolerance, comorbidity, overlapping genetic contribution, neurobiological mechanisms, and response to treatment, supporting the DSM-V Task Force proposed new category of Addiction and Related Disorders encompassing both substance use disorders and non-substance addictions. Current data suggest that this combined category may be appropriate for pathological gambling and a few other better studied behavioral addictions, e.g., Internet addiction. There is currently insufficient data to justify any classification of other proposed behavioral addictions. Proper categorization of behavioral addictions or impulse control disorders has substantial implications for the development of improved prevention and treatment strategies.

  3. Inhibition and impulsivity: behavioral and neural basis of response control.

    Science.gov (United States)

    Bari, Andrea; Robbins, Trevor W

    2013-09-01

    In many circumstances alternative courses of action and thoughts have to be inhibited to allow the emergence of goal-directed behavior. However, this has not been the accepted view in the past and only recently has inhibition earned its own place in the neurosciences as a fundamental cognitive function. In this review we first introduce the concept of inhibition from early psychological speculations based on philosophical theories of the human mind. The broad construct of inhibition is then reduced to its most readily observable component which necessarily is its behavioral manifestation. The study of 'response inhibition' has the advantage of dealing with a relatively simple and straightforward process, the overriding of a planned or already initiated action. Deficient inhibitory processes profoundly affect everyday life, causing impulsive conduct which is generally detrimental for the individual. Impulsivity has been consistently linked to several types of addiction, attention deficit/hyperactivity disorder, mania and other psychiatric conditions. Our discussion of the behavioral assessment of impulsivity will focus on objective laboratory tasks of response inhibition that have been implemented in parallel for humans and other species with relatively few qualitative differences. The translational potential of these measures has greatly improved our knowledge of the neurobiological basis of behavioral inhibition and impulsivity. We will then review the current models of behavioral inhibition along with their expression via underlying brain regions, including those involved in the activation of the brain's emergency 'brake' operation, those engaged in more controlled and sustained inhibitory processes and other ancillary executive functions.

    Concerning the dispositional determinants of prosocial behavior and cooperation, work based on the classic 5 personality factors, and especially Agreeableness, has turned out somewhat inconsistent. A clearer picture has emerged from consideration of the HEXACO model of personality-though supported...... entirely by hypothetical behavior as criterion, so far. Thus, in 2 studies and a reanalysis, we investigated "actual behavior" in the form of individually and socially consequential distribution decisions. As expected, HEXACO Honesty-Humility consistently predicted prosocial behavior, including a theory......-consistent pattern on the facet level. Importantly, this pattern might explain why five-factor Agreeableness has only sometimes been found to account for prosocial behavior. Indeed, further results indicate that five-factor Agreeableness comprises some aspects that are predictive of prosocial behavior-aspects well...

    The maintenance of appropriate social behavior is a very complex process with many contributing factors. Social and moral judgments rely on the proper functioning of neural circuits concerned with complex cognitive and emotional processes. Damage to these systems may lead to distinct social behavior abnormalities. When patients present with dysmoral behavior for the first time, as a change from a prior pervasive pattern of behavior, clinicians need to consider a possible, causative brain disorder. The aim is to explore sociopathy as a manifestation of dementia. We searched electronic databases and key journals for original research and review articles on sociopathy in demented patients using the search terms "sociopathy, acquired sociopathy, sociopathic behavior, dementia, and personality". In conclusion, dementia onset may be heralded by changes in personality including alteration in social interpersonal behavior, personal regulation, and empathy. The sociopathy of dementia differs from antisocial/psychopathic personality disorders.

  6. About Teleological Behaviorism.

    Misconceptions abound about teleological behaviorism (TB). Because very few people other than the author publicly call themselves teleological behaviorists, the fault must be mine. The present article is an attempt to clear up those misconceptions. First I will try to indicate what teleological behaviorism is not. Then, in the form of six fables (loosely connected stories, allegories, analogies, fairy tales, and arguments), I will try to give the reader an understanding of what teleological behaviorism actually is.

  7. Oxytocin and Parental Behaviors.

    The oxytocin/vasopressin ancestor molecule has been regulating reproductive and social behaviors for more than 500 million years. In all mammals, oxytocin is the hormone indispensable for milk-ejection during nursing (maternal milk provision to offspring), a process that is crucial for successful mammalian parental care. In laboratory mice, a remarkable transcriptional activation occurs during parental behavior within the anterior commissural nucleus (AC), the largest magnocellular oxytocin cell population within the medial preoptic area (although the transcriptional activation was limited to non-oxytocinergic neurons in the AC). Furthermore, there are numerous recent reports on oxytocin's involvement in positive social behaviors in animals and humans. Given all those, the essential involvement of oxytocin in maternal/parental behaviors may seem obvious, but basic researchers are still struggling to pin down the exact role oxytocin plays in the regulation of parental behaviors. A major aim of this review is to more clearly define this role. The best conclusion at this moment is that OT can facilitate the onset of parental behavior, or parental behavior under stressful conditions.In this chapter, we will first review the basics of rodent parental behavior. Next, the neuroanatomy of oxytocin systems with respect to parental behavior in laboratory mice will be introduced. Then, the research history on the functional relationship between oxytocin and parental behavior, along with advancements in various techniques, will be reviewed. Finally, some technical considerations in conducting behavioral experiments on parental behavior in rodents will be addressed, with the aim of shedding light on certain pitfalls that should be avoided, so that the progress of research in this field will be facilitated. In this age of populism, researchers should strive to do even more scholarly works with further attention to methodological details.

    2017-10-01

    The long-term change (1974-1998) of the pelagic copepod community in the Kuroshio region, western Pacific was examined in archival samples collected both day and night in April/May in a time period of profound changes in the pelagic fish populations. A total of 162 adult copepod species was found. The community analysis based on species composition and abundance of adult copepods identified five assemblages (A-E) by cluster analysis. These assemblages were distributed in the north-frontal area of the Kuroshio Current within the slope area (A), the Kuroshio axis area (B), the subtropical area (C, D), and the coastal area within the slope area (E), indicating that such diverse communities were formed to correspond with the gradual change in the oceanic environment across the Kuroshio Current. The abundance of copepods in the north-frontal area of the Kuroshio Current (A) was 1.6 times greater than that of the other assemblages. Kuroshio/subtropical species were abundant in the assemblage, suggesting that these species that were transported from the Kuroshio and/or subtropical regions increased in the slope region. Abundance and species richness of two assemblages (C, D), which were found in the subtropical areas were higher at night (C) than during the day (D), suggesting that diel vertical migration of copepods is one of the most important factors affecting changes in the community. Furthermore, a generalized additive model revealed that the most dominant subtropical/Kuroshio species increased in years in which the Kuroshio Current flowed further south, with the Kuroshio axis located far from the Japanese coast. In contrast, the model showed that the lower latitude of the Kuroshio axis positioned negatively affected coastal-dominant species, such as Paracalanus parvus sensu lato (s.l.). These results indicate that onshore-offshore shifts of the Kuroshio axis caused by Kuroshio meandering was an important factor involved in the inter-annual change in the copepod

  14. The role of the hippocampus in flexible cognition and social behavior

    Directory of Open Access Journals (Sweden)

    Rachael D Rubin

    2014-09-01

    Full Text Available Successful behavior requires actively acquiring and representing information about the environment and people, and manipulating and using those acquired representations flexibly to optimally act in and on the world. The frontal lobes have figured prominently in most accounts of flexible or goal-directed behavior, as evidenced by often-reported behavioral inflexibility in individuals with frontal lobe dysfunction. Here, we propose that the hippocampus also plays a critical role by forming and reconstructing relational memory representations that underlie flexible cognition and social behavior. There is mounting evidence that damage to the hippocampus can produce inflexible and maladaptive behavior when such behavior places high demands on the generation, recombination, and flexible use of information. This is seen in abilities as diverse as memory, navigation, exploration, imagination, creativity, decision-making, character judgments, establishing and maintaining social bonds, empathy, social discourse, and language use. Thus, the hippocampus, together with its extensive interconnections with other neural systems, supports the flexible use of information in general. Further, we suggest that this understanding has important clinical implications. Hippocampal abnormalities can produce profound deficits in real-world situations, which typically place high demands on the flexible use of information, but are not always obvious on diagnostic tools tuned to frontal lobe function. This review documents the role of the hippocampus in supporting flexible representations and aims to expand our understanding of the dynamic networks that operate as we move through and create meaning of our world.

    Over the past decade, the number of deaf children with developmental disabilities receiving cochlear implants has increased dramatically. However, little is known about the developmental outcomes of these children post-implantation. The current study evaluated oral language and behavioral outcomes over 3 years after implantation in a sample of typically developing deaf children and children with developmental disabilities. A three year longitudinal study of the effects of cochlear implantation on language and behavioral outcomes in children with and without additional disabilities. Six cochlear implant centers in the United States. The study cohort consisted of 188 deaf children. Eighty-five percent of the sample (n = 157) had a single diagnosis of severe to profound hearing loss and 15% (n = 31) had an additional disability. Oral language was assessed using the Reynell Developmental Language Scales, and behavioral outcomes were assessed using the Child Behavior Checklist. Results using multilevel modeling indicated that deaf children with and without additional disabilities improved significantly in oral language skills post-implantation. However, children with additional disabilities made slower progress. In terms of specific diagnoses, children with developmental disorders, such as autism, made the slowest progress over time. In addition, behavior problems increased significantly in this group, whereas behavior problems decreased over 3 years in the typically developing deaf sample. Overall, given the improvements in expressive and receptive language skills documented over 3 years, these findings support the use of cochlear implants for deaf children with developmental disabilities.

    In the United States, African-American women are at disproportionate risk for contracting human immunodeficiency virus (HIV) and face the most profound burden of HIV infection. Reducing the risk of exposure to HIV in African-American women is a priority for health-care providers. The findings of this study add to the existing literature by examining the relationship of self-esteem and risky sexual behaviors in young African-American women. Lack of self-esteem was one of the themes that emerged from a larger study that investigated how African-American women define HIV-risky behavior. In the current study, quantitative and qualitative data were collected from a convenience sample of 33 African-American women (N = 33) from three metropolitan regions within Michigan. Findings highlight the importance of understanding the relationship between self-esteem and its implications for HIV/sexually transmitted disease (STD) prevention.

    Peer influence has a profound impact on decision-making in typically developing adolescents. In this study, we examined to what extent adolescent males (age 11-17 years; N = 144) with and without autism (ASD) were influenced by peer feedback on prosocial behavior, and which factors were related to individual differences in peer feedback sensitivity. In a public goods game, participants made decisions about the allocation of tokens between themselves and their group-in absence or presence of peer feedback. Adolescents with and without ASD were sensitive to peer feedback on prosocial behavior. More autism traits and social interest were associated with less sensitivity to antisocial feedback, suggesting that peer feedback creates opportunities for social adjustment in those with and without ASD.

    Bell, Jeffrey G; Wang, Jichang

    2015-04-09

    Investigation illustrates that the bromate-4-nitrophenol reaction in a stirred batch reactor undergoes spontaneous oscillations under very broad initial reactant concentrations. The addition of ferroin has subtle influences on the nonlinear behavior, in which the frequency and total number of oscillations were greatly reduced at a low or high ferroin concentration, as opposed to the significant increase at a moderate ferroin concentration. Temporal oscillations with a modulating frequency were also observed in the ferroin-bromate-4-nitrophenol system. In a capillary tube the ferroin-bromate-4-nitrophenol reaction generated propagating wave trains with various complex behaviors such as period-doubled intermittent propagation failure. Illumination was found to have a profound effect on the temporal oscillations in the bromate-4-nitrophenol reaction and on those long lasting wave activities. Spectroscopic studies were able to identify 1,4-benzoquinone, 2-bromo-1,4-benzoquinone, and 2-bromo-4-nitrophenol as major components during the reaction.

    We describe the scientific enterprise at the intersection of evolutionary psychology and behavioral genetics-a field that could be termed Evolutionary Behavioral Genetics-and how modern genetic data is revolutionizing our ability to test questions in this field. We first explain how genetically informative data and designs can be used to investigate questions about the evolution of human behavior, and describe some of the findings arising from these approaches. Second, we explain how evolutionary theory can be applied to the investigation of behavioral genetic variation. We give examples of how new data and methods provide insight into the genetic architecture of behavioral variation and what this tells us about the evolutionary processes that acted on the underlying causal genetic variants.

    Full Text Available In article Ajzen-Fishbein's attitude-behavior model called 'Theory of reasoned action' and Albert Bandura's Model of reciprocal determinism are presented. Both models are a part of social-cognitive paradigm which characterizes behavior with evaluation of different goals. Ajzen and Fishbein (1973; 1980 proposed that specific behavior are predictable from specific behavioral intentions. These intentions are a function of two components: the attitude toward the act in question and percieved normative expectations of reference group. On the other hand Bandura (1986; 1997 claims that person's motivation for a specific behavior and direction toward a specific social object respectively, reflects perception of his or hers self-efficacy beliefs. Some of the findings concerning the synthesis of the two models are also reviewed.

    Science.gov (United States)

    Halberstadt, Adam L; Geyer, Mark A

    2011-09-01

    Serotonergic hallucinogens produce profound changes in perception, mood, and cognition. These drugs include phenylalkylamines such as mescaline and 2,5-dimethoxy-4-methylamphetamine (DOM), and indoleamines such as (+)-lysergic acid diethylamide (LSD) and psilocybin. Despite their differences in chemical structure, the two classes of hallucinogens produce remarkably similar subjective effects in humans, and induce cross-tolerance. The phenylalkylamine hallucinogens are selective 5-HT(2) receptor agonists, whereas the indoleamines are relatively non-selective for serotonin (5-HT) receptors. There is extensive evidence, from both animal and human studies, that the characteristic effects of hallucinogens are mediated by interactions with the 5-HT(2A) receptor. Nevertheless, there is also evidence that interactions with other receptor sites contribute to the psychopharmacological and behavioral effects of the indoleamine hallucinogens. This article reviews the evidence demonstrating that the effects of indoleamine hallucinogens in a variety of animal behavioral paradigms are mediated by both 5-HT(2) and non-5-HT(2) receptors.

  14. Phase behavior of charged colloids on spherical surfaces

    Science.gov (United States)

    Kelleher, Colm; Guerra, Rodrigo; Chaikin, Paul

    For a broad class of 2D materials, the transition from isotropic fluid to crystalline solid is described by the theory of melting due to Kosterlitz, Thouless, Halperin, Nelson and Young. According to this theory, long-range order is achieved via elimination of the topological defects which proliferate in the fluid phase. However, many natural and man-made 2D systems posses spatial curvature and/or non-trivial topology, which require the presence of defects, even at T = 0 . In principle, the presence of these defects could profoundly affect the phase behavior of such a system. In this presentation, we describe experiments and simulations we have performed on repulsive particles which are bound to the surface of a sphere. We observe spatial structures and inhomogeneous dynamics that cannot be captured by the measures traditionally used to describe flat-space phase behavior. We show that ordering is achieved by a novel mechanism: sequestration of topological defects into freely-terminating grain boundaries (``scars''), and simultaneous spatial organization of the scars themselves on the vertices of an icosahedron. The emergence of icosahedral order coincides with the localization of mobility into isolated ``lakes'' of fluid or glassy particles, situated at the icosahedron vertices.

    2011-01-01

    Background Several behaviors, besides psychoactive substance ingestion, produce short-term reward that may engender persistent behavior despite knowledge of adverse consequences, i.e., diminished control over the behavior. These disorders have historically been conceptualized in several ways. One view posits these disorders as lying along an impulsive-compulsive spectrum, with some classified as impulse control disorders. An alternate, but not mutually exclusive, conceptualization considers the disorders as non-substance or “behavioral” addictions. Objectives Inform the discussion on the relationship between psychoactive substance and behavioral addictions. Methods: We review data illustrating similarities and differences between impulse control disorders or behavioral addictions and substance addictions. This topic is particularly relevant to the optimal classification of these disorders in the forthcoming fifth edition of the American Psychiatric Association Diagnostic and Statistical Manual of Mental Disorders. Results Growing evidence suggests that behavioral addictions resemble substance addictions in many domains, including natural history, phenomenology, tolerance, comorbidity, overlapping genetic contribution, neurobiological mechanisms, and response to treatment, supporting the DSM-V Task Force proposed new category of Addiction and Related Disorders encompassing both substance use disorders and non-substance addictions. Current data suggest that this combined category may be appropriate for pathological gambling and a few other better studied behavioral addictions, e.g., Internet addiction. There is currently insufficient data to justify any classification of other proposed behavioral addictions. Conclusions and Scientific Significance Proper categorization of behavioral addictions or impulse control disorders has substantial implications for the development of improved prevention and treatment strategies.

    Behavior modification, as the core of clinical behavioral medicine, is often used in clinical settings. We seek to summarize behavior modification techniques that are commonly used in clinical practice of behavioral medicine in China and discuss possible biobehavioral mechanisms. We reviewed common behavior modification techniques in clinical settings in China, and we reviewed studies that explored possible biobehavioral mechanisms. Commonly used clinical approaches of behavior modification in China include behavior therapy, cognitive therapy, cognitive-behavioral therapy, health education, behavior management, behavioral relaxation training, stress management intervention, desensitization therapy, biofeedback therapy, and music therapy. These techniques have been applied in the clinical treatment of a variety of diseases, such as chronic diseases, psychosomatic diseases, and psychological disorders. The biobehavioral mechanisms of these techniques involve the autonomic nervous system, neuroendocrine system, neurobiochemistry, and neuroplasticity. Behavior modification techniques are commonly used in the treatment of a variety of somatic and psychological disorders in China. Multiple biobehavioral mechanisms are involved in successful behavior modification.

    To evaluate and compare the benefit of a bone-anchored hearing implant with 2 different sound processors in adult patients with unilateral severe to profound sensorineural hearing loss (UHL). Prospective crossover design. Tertiary referral center. Eleven adults with UHL and normal hearing in the contralateral ear were assigned to 2 groups. All subjects were unilaterally implanted with a bone-anchored hearing implant and were initially fitted with 2 different sound processors (SP-1 and SP-2). SP-1 is a multichannel device equipped with an omnidirectional microphone and relatively simple digital signal-processing technology and provides a user-adjustable overall gain and tone control with compression limiting. SP-2 is a fully channel-by-channel programmable device, which can be set with nonlinear dynamic range compression or linear amplification. In addition, SP-2 features automatic noise management, an automatic multichannel directional microphone, microphone position compensation, and an implementation of prescription rules for different types of hearing losses, one of them unilateral deafness. After at least 1-month use of the initial processor, both groups were fitted with the alternative processor. Speech discrimination in noise and localization tests were performed at baseline visit before surgery, after at least 1-month use of the initial processor, and after at least 2-week use of the alternative processor. Relative to unaided baseline, SP-2 enabled significantly better overall speech discrimination results, whereas there was no overall improvement with SP-1. There was no difference in speech discrimination between SP-1 and SP-2 in all spatial settings. Sound localization was comparably poor at baseline and with both processors but significantly better than chance level for all 3 conditions. Patients with UHL have an overall objective benefit for speech discrimination in noise using a bone-anchored hearing implant with SP-2. In contrast, there is no overall

  3. Genetic Influences on Adolescent Sexual Behavior: Why Genes Matter for Environmentally-Oriented Researchers

    There are dramatic individual differences among adolescents in how and when they become sexually active adults, and “early” sexual activity is frequently cited as a cause of concern for scientists, policymakers, and the general public. Understanding the causes and developmental impact of adolescent sexual activity can be furthered by considering genes as a source of individual differences. Quantitative behavioral genetics (i.e., twin and family studies) and candidate gene association studies now provide clear evidence for the genetic underpinnings of individual differences in adolescent sexual behavior and related phenotypes. Genetic influences on sexual behavior may operate through a variety of direct and indirect mechanisms, including pubertal development, testosterone levels, and dopaminergic systems. Genetic differences may be systematically associated with exposure to environments that are commonly treated as causes of sexual behavior (gene-environment correlation). Possible gene-environment correlations pose a serious challenge for interpreting the results of much behavioral research. Multivariate, genetically-informed research on adolescent sexual behavior compares twins and family members as a form of “quasi-experiment”: How do twins who differ in their sexual experiences differ in their later development? The small but growing body of genetically-informed research has already challenged dominant assumptions regarding the etiology and sequelae of adolescent sexual behavior, with some studies indicating possible positive effects of teenage sexuality. Studies of gene × environment interaction may further elucidate the mechanisms by which genes and environments combine to shape the development of sexual behavior and its psychosocial consequences. Overall, the existence of heritable variation in adolescent sexual behavior has profound implications for environmentally-oriented theory and research. PMID:23855958

    Full Text Available The history of behavior analysis in Brazil began with the visit of Fred S. Keller as a FulbrightScholar to the University of São Paulo in 1961. Keller introduced Skinner works to the Brazilianpsychologists. His first assistant was Carolina Martuscelli Bori, then a social psychologistinfluenced by the work of Kurt Lewin. Initially guided by Keller, Carolina Bori was the majorforce in the diffusion of Behavior Analysis in Brazil, beginning with the psychology course ofthe University of Brasília, where the first course on Experimental Analysis of Behavior beganin August of 1964. Most of behavior analysts in Brazil today were students, directly or indirectly,of Carolina Bori. Several graduate programs throughout the country offer courses in behavioranalysis.

    Behavioral public administration is the analysis of public administration from the micro-level perspective of individual behavior and attitudes by drawing on insights from psychology on the behavior of individuals and groups. The authors discuss how scholars in public administration currently draw...... on theories and methods from psychology and related fields and point to research in public administration that could benefit from further integration. An analysis of public administration topics through a psychological lens can be useful to confirm, add nuance to, or extend classical public administration...... theories. As such, behavioral public administration complements traditional public administration. Furthermore, it could be a two-way street for psychologists who want to test the external validity of their theories in a political-administrative setting. Finally, four principles are proposed to narrow...

    Full Text Available Abstract This review focuses on behavioral genetic studies of sweet, umami, bitter and salt taste responses in mammals. Studies involving mouse inbred strain comparisons and genetic analyses, and their impact on elucidation of taste receptors and transduction mechanisms are discussed. Finally, the effect of genetic variation in taste responsiveness on complex traits such as drug intake is considered. Recent advances in development of genomic resources make behavioral genetics a powerful approach for understanding mechanisms of taste.

  16. Francis Bacon's behavioral psychology.

    Science.gov (United States)

    MacDonald, Paul S

    2007-01-01

    Francis Bacon offers two accounts of the nature and function of the human mind: one is a medical-physical account of the composition and operation of spirits specific to human beings, the other is a behavioral account of the character and activities of individual persons. The medical-physical account is a run-of-the-mill version of the late Renaissance model of elemental constituents and humoral temperaments. The other, less well-known, behavioral account represents an unusual position in early modern philosophy. This theory espouses a form of behavioral psychology according to which (a) supposed mental properties are "hidden forms" best described in dispositional terms, (b) the true character of an individual can be discovered in his observable behavior, and (c) an "informed" understanding of these properties permits the prediction and control of human behavior. Both of Bacon's theories of human nature fall under his general notion of systematic science: his medical-physical theory of vital spirits is theoretical natural philosophy and his behavioral theory of disposition and expression is operative natural philosophy. Because natural philosophy as a whole is "the inquiry of causes and the production of effects," knowledge of human nature falls under the same two-part definition. It is an inquisition of forms that pertains to the patterns of minute motions in the vital spirits and the production of effects that pertains both to the way these hidden motions produce behavioral effects and to the way in which a skillful agent is able to produce desired effects in other persons' behavior.

    We develop a theory of prosocial behavior that combines heterogeneity in individual altruism and greed with concerns for social reputation or self-respect. Rewards or punishments (whether material or image-related) create doubt about the true motive for which good deeds are performed, and this ?overjustification effect? can induce a partial or even net crowding out of prosocial behavior by extrinsic incentives. We also identify the settings that are conducive to multiple social norms and, mor...
