Co‐constructed talk in the conversations of people with dysarthria and aphasia

This paper uses the methodology of conversation analysis (CA) to examine the practice of co‐constructed turn and utterance production in impaired communication. An investigation of the conversations between two family dyads, featuring one person with dysarthric speech and one with aphasic language, reveals one way in which single turns and utterances are produced through the collaborative activities of two people in interaction. Such a practice is shown to operate without problems for the participants or the need for explicit acceptance by the speakers. It is proposed that co‐construction in disordered speech and language is one way in which communicative competence is accomplished. By drawing attention to similarities in the consequences of dysarthria and aphasia in everyday interaction, it is suggested that researchers and clinicians might profitably look across disorder‐specific boundaries.     

Can verbal instruction enhance the recall of an everyday task and promote error-monitoring in people with dementia of the Alzheimer-type?

People with dementia of the Alzheimer-type (DAT) have difficulties with performing everyday tasks, and error awareness is poor. Here we investigate whether recall of actions and error monitoring in everyday task performance improved when they instructed another person on how to make tea. In this situation, both visual and motor cues are present, and attention is sustained by the requirement to keep instructing. The data were drawn from a longitudinal study recording performance in four participants with DAT, filmed regularly for five years in their own homes, completing three tea-making conditions: performed-recall (they made tea themselves); instructed-recall (they instructed the experimenter on how to make tea); and verbal-recall (they described how to make tea). Accomplishment scores (percentage of task they correctly recalled), errors and error-monitoring were coded. Task accomplishment was comparable in the performed-recall and instructed-recall conditions, but both were significantly better than task accomplishment in the verbal-recall condition. Third person instruction did not improve error-monitoring. This study has implications for everyday task rehabilitation for people with DAT.     

How does drug and alcohol misuse develop among people with psychotic illness? A literature review

Background: There is little evidence contributing to the understanding of why people with schizophrenia and other psychotic illnesses use drugs and alcohol. Method: A comprehensive literature search for evidence relevant to each of the following questions was undertaken, each of which is relevant to understanding why individuals with schizophrenia and other functional psychotic illnesses use drugs and alcohol: (1) Is substance misuse more prevalent among those with psychotic illness than the general Population? (2) Which problem generally develops first in dual diagnosis? (3) Can substance misuse cause schizophrenia and other functional psychotic illnesses? (4) Does dual diagnosis have a neurobiological Basis? (5) Is personality disorder a mediating factor in the relationship between psychotic illnesses and substance misuse? (6) Do individuals with psychotic illness use substances as self-medication? (7) Have changes in the care and social circumstances of people with psychotic illness, particularly deinstitutionalisation, led to a rise in substance misuse in this Population? (8) Do the social situations and social difficulties of people with psychotic illness lead to substance misuse? and (9) Do individuals with psychotic illness tend to begin using drugs and alcohol within mental health service settings or in the company of other users of such services? Results: There is some evidence to support the idea that people with schizophrenia and other psychotic disorders use substances to reduce general dysphoria, and possibly negative symptoms. Social environment and experiences are also likely to be factors in the development of substance misuse in this group, but there is a dearth of empirical evidence. Conclusions: There is a need for further research, especially concerning the social contexts of substance and alcohol misuse and the ways in which patterns of misuse develop among people with schizophrenia and other psychotic illnesses.     

Tremor associated with Klinefelter syndrome – A case series and review of the literature

BackgroundPrevious case series suggested a link between Klinefelter syndrome (KS) and essential tremor (ET) or an ET-like syndrome.MethodsWe investigated three KS-patients with tremor including tremor-analyzes and discuss our data in context to findings from a literature review. The clinical outcome after deep brain stimulation (DBS) is also reviewed.ResultsTremor in KS is predominantly a postural and kinetic tremor that resembles ET. Our patients were further characterized by absent family history for tremor in first degree relatives, lack of subjective alcohol responsiveness inquired by history, and tremor onset in childhood. One of our patients and two cases from literature improved after DBS of the ventral intermediate nucleus (VIM) of the thalamus.ConclusionsTremor in KS shares several features with ET. If other characteristics such as family history, alcohol responsiveness, and age at tremor onset may serve as discriminating factors from ET, needs to be further investigated. First observations suggest that VIM-DBS may be efficacious.     

How intensive does anomia therapy for people with aphasia need to be?

The intensity of aphasia therapy has been a key clinical question. The aim of this case-series study was to compare the outcome of intensive and non-intensive therapy in the relearning of words for people with aphasia. Eight participants took part in a study comparing the intensity of delivery of the therapy. Participants received two courses of the same therapy (each lasting 10 sessions) delivered either intensively or non-intensively. Therapy consisted of confrontation naming with progressive phonemic and orthographic cues. Post-therapy assessments were carried out immediately after the study and one month later. Performance was also monitored during each therapy session. Immediately post-therapy, both types of therapy had improved naming accuracy considerably and there was no significant difference between the two interventions. One month later, seven out of eight participants showed a small yet significant difference in naming accuracy, favouring non-intensive over intense therapy. There were no differences in the learning patterns during the therapy sessions between the intensive and non-intensive therapies. For the majority of people with aphasia post-stroke, both intense and non-intense therapy for anomia leads to improved naming performance. Retention at one-month post therapy is relatively superior after non-intensive therapy.     

Can we use peripheral tissue biopsies to diagnose Parkinson's disease? A review of the literature

Phosphorylated α‐synuclein (phosαSYN) containing inclusions in neurons (Lewy bodies, LB) and nerve terminals (Lewy neurites, LN), the pathological hallmark of Parkinson's disease (PD), are not confined to the central nervous system, but have also been reported in peripheral tissues. However, the usefulness of αSYN/phosαSYN detection in tissues accessible to biopsies as a reliable biomarker for prodromal PD remains unclear. A systematic review of studies using biopsies of skin, olfactory and gastrointestinal (GI) tissues was conducted to evaluate the sensitivity and specificity of both αSYN and phosαSYN staining in PD patients. Data analysis was hampered by the diversity of the methods used, e.g. choice of biopsy sites, tissue processing, staining protocols and evaluation of the findings. Tissue obtained from GI tract/salivary glands (13 post‐mortem, 13 in vivo studies) yielded the highest overall sensitivity and specificity compared to skin (three post‐mortem, eight in vivo studies) and olfactory mucosa/bulb (six post‐mortem studies, one in vivo study). In contrast to phosαSYN, αSYN was more consistently detectable in peripheral tissues of healthy controls. GI tract/salivary glands appear to be the most promising candidate tissue for peripheral biopsy‐taking. phosαSYN is considered as the marker of choice to delineate pathological aggregates from normal αSYN regularly found in peripheral neural tissues. However, the sensitivity and specificity of phosαSYN are not yet acceptable for using phosαSYN as a reliable peripheral biomarker for PD in clinical routine. Further refinement regarding the interpretation of the peripheral αSYN/phosαSYN burden and the phenotypical definition of peripheral LB/LN is needed to optimize screening methods for prodromal PD.     

Does vaginismus exist? A critical review of the literature.

The basic strategies and methods for assessing and treating vaginismus were proposed by the early 20th century and have not essentially changed. Etiological theories have changed over time but are not supported by controlled empirical studies. This critical review of the literature disputes the widely held belief that vaginismus is an easily diagnosed and easily treated sexual dysfunction. We propose a reconceptualization of vaginismus as either an aversion/phobia of vaginal penetration or a genital pain disorder.     

Active involvement of people with intellectual disabilities in health research – A structured literature review

Actively involving people with intellectual disabilities (ID) in health research, also known as inclusive health research, is increasingly popular. Currently, insight into experiences of this type of research is scarce. To gain insight into this topic, a structured literature review was conducted focussing on (1) existing theories, (2) inclusive methods, (3) added value and (4) barriers and facilitators. Literature published between January 2000 and January 2014 was included covering keywords related to ID and inclusive health research. Searches were performed in Pubmed, CINAHL, PsycINFO, EMBASE and MEDLINE databases, resulting in 26 included papers. Papers were quality assessed and analysed using qualitative data analysis software. Four theories were often simultaneously addressed: participatory research, emancipatory research, inclusive research and Arnstein's ladder. Barriers and facilitators could be divided into preparing, undertaking and finalising phases of research. Authors indicated that their motivation to conduct inclusive health research was based on demands by policy and funding bodies or was based on ethical considerations (i.e., ethical notions and giving people with ID a voice). Upon completion, authors perceived increased quality and validity of their research and several benefits for stakeholders (i.e., people with ID, researchers and healthcare professionals). Overall, there was consistency in their perception of the most important aspects of inclusive health research. Based on the analysis of included papers, four recommendations of inclusive health research with people with ID were found. Inclusive health research should be: (1) tailoring to the specific study; (2) anticipating all stakeholders; (3) considering its added value; and (4) providing insight into its process.     

Is panic disorder associated with coronary artery disease? A critical review of the literature

OBJECTIVE: To critically review existing literature examining the relationship between panic disorder (PD) and coronary artery disease (CAD). We specifically sought answers to the following questions: (1) What is the prevalence of PD in CAD patients? (2) What is the directionality of the relationship between PD and CAD? (3) What mechanisms may mediate the link between PD and CAD? METHODS: Medline and Psychlit searches were conducted using the following search titles: "panic disorder and coronary artery disease", "panic disorder and coronary heart disease", and "panic disorder and cardiovascular disease" for the years 1980-1998. The above search was also repeated replacing "panic disorder" with "panic attacks" for the same period. RESULTS: The prevalence of PD in both cardiology out-patients and patients with documented CAD ranges from 10% to 50%. The association between PD and CAD appeared strongest in patients with atypical chest pain or symptoms that could not be fully explained by coronary status. There is some evidence linking phobic anxiety but not PD per se to CAD risk, but little evidence linking CAD to PD risk. Studies of the mechanisms linking PD to CAD are still in their infancy, but there is preliminary evidence linking PD to reduced heart rate variability (HRV) and myocardial ischemia, two pathophysiological mechanisms related to CAD. CONCLUSION: PD is prevalent in CAD patients, but it is unclear the extent to which PD confers risk for and/or exacerbates CAD. Prospective research is needed to more firmly establish PD as a distinct risk factor for the development and progression of CAD. However, because many of the symptoms of PD mimic those of CAD, differentiating these disorders and learning how they may influence each other is imperative for clinical practice.     

Rehabilitation of adolescent patients with scoliosis—what do we know? A review of the literature

Different opinions exist about the efficacy of conservative scoliosis treatment. Because this divergence of opinion corresponds to a great variety of standards applied, it is also not surprising that the results of conservative treatment differ a lot. Scoliosis normally does not have such dramatic effects that immediate surgery would be indicated. Moreover, it is clear that functional and physiological impairments of scoliosis patients—including pain, torso deformity, psychological disturbance and pulmonary dysfunction—require therapeutic intervention. The triad of out-patient physiotherapy, intensive in-patient rehabilitation and bracing has proven effective in conservative scoliosis treatment in central Europe. Indication, content and results of the individual treatment procedures are described and discussed. The positive outcomes of this practice validate a policy of offering conservative treatment as an alternative to scoliosis patients, including those for whom surgery is discussed.     

Health information exchange in general practice care for people with intellectual disabilities—A qualitative review of the literature

Many barriers to the provision of general practice (GP) care for people with intellectual disabilities (ID) relate to problems in exchanging health information. Deficits in the exchange of health information may have an adverse impact on healthcare access and health outcomes in individuals with ID. The aim of this paper is to report how health information exchange (HIE) in GP care for people with ID is being described in the ID healthcare literature. Thematic analysis of 19 included articles resulted in six major themes: (1) communication skills; (2) organisational factors; (3) record keeping and sharing; (4) health literacy and self-advocacy; (5) carers and health professionals’ knowledge; and (6) third parties. The results indicate that HIE takes place in a chain of events happening before, during, and after a medical consultation, depending on specific contextual care factors. The included papers lack a broad focus on the entire HIE process, and causes and effects of gaps in health information are described only marginally or on a very general level. However, a study of the HIE process in its entirety is imperative in order to identify weak links and gaps in information pathways. The themes presented here provide a starting point for an in-depth study on the HIE process in GP care for individuals with ID that may facilitate future research on health interventions in this setting.     

Does thyroid supplementation accelerate tricyclic antidepressant response? A review and meta-analysis of the literature

OBJECTIVE: The delayed onset of therapeutic response to antidepressants remains a major problem in the treatment of depression. Among the strategies to accelerate response to treatment, the early addition of thyroid hormone to antidepressants has been suggested as a viable method. The authors performed a meta-analysis of the literature on the use of thyroid hormone supplementation to accelerate the treatment of depression to determine whether there is sufficient evidence to support the clinical efficacy of this strategy. METHOD: Both a computer-aided search of the National Library of Medicine MEDLINE and an intensive search by hand were conducted to identify all double-blind, placebo-controlled studies assessing the concomitant administration of thyroid hormone and antidepressant to accelerate clinical response in patients with nonrefractory depression. RESULTS: Six studies were identified. All were conducted with triiodothyronine (T(3)) and a tricyclic antidepressant. Five of the six studies found T(3) to be significantly more effective than placebo in accelerating clinical response. The pooled, weighted effect size index was 0.58, and the average effect was highly significant. Further, the effects of T(3) acceleration were greater as the percentage of women participating in the study increased. CONCLUSIONS: This meta-analysis supports the efficacy of T(3) in accelerating clinical response to tricyclic antidepressants in patients with nonrefractory depression. Furthermore, women may be more likely than men to benefit from this intervention.     

Current approaches and future directions of gene therapy in Alzheimer’s disease

We review the results of preclinical studies and clinical trials of gene therapy for the treatment of Alzheimer’s disease. The possible application of gene-therapy approaches is discussed from the point of view of the pathogenesis of this disease. The problems and future directions of the clinical use of gene therapy for the treatment of Alzheimer’s disease are discussed.     

Medical students’ attitudes towards people with intellectual disabilities: A literature review

The present paper provides a review of research on medical students’ attitudes to people with intellectual disabilities. The attitudes of medical students warrant empirical attention because their future work may determine people with intellectual disabilities’ access to healthcare and exposure to health inequalities. An electronic search of Embase, Ovid MEDLINE(R), PsycINFO, Scopus, and Web of Science was completed to identify papers published up to August 2013. Twenty-four studies were identified, most of which evaluated the effects of pedagogical interventions on students’ attitudes. Results suggested that medical students’ attitudes to people with intellectual disabilities were responsive to interventions. However, the evidence is restricted due to research limitations, including poor measurement, self-selection bias, and the absence of control groups when evaluating interventions. Thus, there is a dearth of high-quality research on this topic, and past findings should be interpreted with caution. Future research directions are provided.     

Do occupational therapy interventions improve quality of life in persons with dementia? A meta‐analysis with implications for future directions

Occupational therapy (OT) interventions have shown positive effects on physical functioning in persons with dementia (PwD). However, their effect on quality of life (QoL) has been inconsistent in individual clinical trials. The present review appraises current evidence for the use of OT interventions in improving QoL of PwD. Records in the Cochrane Database, MEDLINE, EMBASE, PsycINFO, and Cumulative Index to Nursing and Allied Health Literature were searched for relevant citations, and PubMed was searched for in‐process articles. Additional searches of the reference lists of retrieved articles were undertaken. Ten studies involving 1002 PwD met the criteria for syntheses. OT intervention produced small non‐significant improvements in overall QoL. The evidence from the present review does not support the specific use of OT interventions for the improvement of QoL in PwD under pragmatic clinical conditions at this time. They may be best used as part of a comprehensive range of interventions for PwD. Recommendations are made for future design of OT interventions focusing on the improvement of QoL, which is central to the well‐being of PwD.
