Noor Gul, Ijaz Mansoor Qureshi, Adnan Omar, Atif Elahi, Sajjad Khan
In cognitive radio communication, spectrum sensing plays a vital role in sensing the existence of the primary user (PU). The sensing performance is badly affected by fading and shadowing in case of single secondary user(SU). To overcome this issue, cooperative spectrum sensing (CSS) is proposed. Although the reliability of the system is improved with cooperation but existence of malicious user (MU) in the CSS deteriorates the performance. In this work, we consider the Kullback-Leibler (KL) divergence method for minimizing spectrum sensing data falsification (SSDF) attack...

Iris Torchalla, Verena Strehlau
The purpose of this study was to summarize the evidence base for interventions targeting individuals with work-related posttraumatic stress disorder (PTSD), to make recommendations for clinicians and administrative decision makers involved in their rehabilitation, and to guide future research in this area. Particular attention was given to studies that were conducted in naturalistic clinical settings or in a workers' compensation claim context. Electronic searches of Cochrane Central Register of Controlled Trials, MEDLINE, PubMed, PsycINFO, CINAHL, PILOTS, and EMBASE identified 11 articles...

Morris Gordon, Dillan Parakh
BACKGROUND: Errors in healthcare are a major patient safety issue, with incident reporting a key solution. The incident reporting system has been integrated within a new medical curriculum, encouraging medical students to take part in this key safety process. The aim of this study was to describe the system and assess how students perceived the reporting system with regards to its role in enhancing safety. METHODS: Employing a thematic analysis, this study used interviews with medical students at the end of the first year...

BACKGROUND: The aim of the study was to address issues arising from fracture of the femoral neck in elderly individuals, the prevalence of which continues to increase in Japan. The prevalence is increasing in Japan and there have been many reports on physical functions such as prevention of a fall. However, there have been a few studies that focus on psycho-cognitive functions. We must examine factors in patients with fractured femur necks to develop methods to assist affected patients...

Impaired analysis of signal conflict and congruence may contribute to diverse socio-emotional symptoms in frontotemporal dementias, however the underlying mechanisms have not been defined. Here we addressed this issue in patients with behavioural variant frontotemporal dementia (bvFTD; n=19) and semantic dementia (SD; n=10) relative to healthy older individuals (n=20). We created auditory scenes in which semantic and emotional congruity of constituent sounds were independently probed; associated tasks controlled for auditory perceptual similarity, scene parsing and semantic competence...

BACKGROUND: Patients who return to the Emergency Department (ED) within 72h of discharge are often used for ED Quality Assurance efforts, however little is known about the yield of this kind of review and the types of errors it identifies. Our objective was to identify the prevalence, types and severity of errors in these cases. METHODS: Retrospective review of patients who presented to an urban, university affiliated ED between 10/1/2012-9/30/2015 who returned within 72 h requiring hospital admission...

Over the last 20 years, studies have provided greater insight into disorders of consciousness (DOC), also known as altered state of consciousness. Increased brain residual functions have been identified in patients with DOC due to the successful application of novel next-generation imaging technologies. Many unconscious patients have now been confirmed to retain considerable cognitive functions. It is hoped that greater insight regarding the psychological state of patients may be achieved through the use of functional magnetic resonance imaging and brain-computer interfaces...

Obesity is recognised as a multidetermined issue. However, research aimed at addressing diet failure has typically examined factors in isolation. Furthermore, previous research has included limited input from dieters themselves. A qualitative study identified a number of themes contributing to diet failure. This study aimed to test these themes with a larger sample ( n = 426) while also determining their fit within a multifactorial model. The results of this study supported the conceptualisation of diet failure using a multifactorial model while also illustrating correlational pathways to be more complex than currently understood in the literature...

Safety is an issue for older adults with dementia because they are at risk for various incidents. Intelligent assistive technology (IAT) may mitigate risks while promoting independence and reducing the impact on the caregiver of supporting a relative with dementia. The aim of this scoping review was to describe IATs and to identify factors to consider when selecting one. A systematic search was performed of the scientific and gray literature published between 2000 and 2015. A total of 31 sources were included...

Acute myeloid leukemia (AML) is an aggressive, acute-onset hematological malignancy. Greater use of intensive chemotherapy (IC), supportive care, and stem cell transplantation have led to an increasing number of long-term survivors. Few studies have examined employment issues among AML survivors and to our knowledge, no study has examined the long-term effects of treatment on return to work. This study is the first to utilize a validated measure of work-related limitation and productivity (WLQ-16) to assess the long-term effects of AML treatment on employment rates, work-related limitations, and overall productivity...

Indu Subramanian
The use of complementary and alternative medicine (CAM) therapy in nonmotor symptoms (NMS) for Parkinson disease (PD) is growing worldwide. Well-performed, systematic evidence-based research is largely lacking in this area and many studies include various forms of CAM with small patient numbers and a lack of standardization of the approaches studied. Taichi, Qigong, dance, yoga, mindfulness, acupuncture, and other CAM therapies are reviewed and there is some evidence for the following: Taichi in sleep and PDQ39; dance in cognition, apathy, and a mild trend to improved fatigue; yoga in PDQ39; and acupuncture in depression, PDQ39, and sleep...

Geraghty's recent editorial on the PACE trial for chronic fatigue syndrome has stimulated a lively discussion. Here, I consider whether the published claims are justified by the data. I also discuss wider issues concerning trial procedures, researcher allegiance and participant reporting bias. Cognitive behavioural therapy and graded exercise therapy had modest, time-limited effects on self-report measures, but little effect on more objective measures such as fitness and employment status. Given that the trial was non-blinded, and the favoured treatments were promoted to participants as 'highly effective', these effects may reflect participant response bias...

Reporting of harms was much better in the PACE (Pacing, graded Activity, and Cognitive behavioural therapy: a randomised Evaluation) trial than earlier chronic fatigue syndrome trials of graded exercise therapy and cognitive behavioural therapy. However, some issues remain. The trial's poor results on objective measures of fitness suggest a lack of adherence to the activity component of these therapies. Therefore, the safety findings may not apply in other clinical contexts. Outside of clinical trials, many patients report deterioration with cognitive behavioural therapy and particularly graded exercise therapy...

Crowdsourcing data collection from research participants recruited from online labor markets is now common in cognitive science. We review who is in the crowd and who can be reached by the average laboratory. We discuss reproducibility and review some recent methodological innovations for online experiments. We consider the design of research studies and arising ethical issues. We review how to code experiments for the web, what is known about video and audio presentation, and the measurement of reaction times...

BACKGROUND: Atrial fibrillation (AF) and dementia are largely prevalent and incident in progressively older subjects, suggesting a link between the two conditions. While in the general population there are several findings supporting a causal relationship between AF and dementia, it is unclear whether or not this association is still present in individuals aged 80 and older. RESULTS: So far, the few studies that analysed this issue did not provide enough evidence supporting the causative role of AF in increasing the risk of cognitive decline or dementia in patients aged 80 and older...

REVIEW
Eric S Zhou, Paula Gardiner, Suzanne M Bertisch
Difficulty initiating and/or maintaining sleep is a common issue. Patients experiencing insomnia symptoms frequently self-treat their symptoms with sleep medications. However, there remains concern regarding the short- and long-term health impacts of sleep medications. This article discusses the evidence supporting integrative approaches to insomnia treatment, including cognitive-behavioral therapy and mind-body therapies (mindfulness meditation, yoga, tai chi), as well as emerging data for use of other less well supported approaches (dietary supplements, acupuncture)...

In-car infotainment systems require icons that enable fluent cognitive information processing and safe interaction while driving. An important issue is how to find an optimised set of icons for different functions in terms of semantic distance. In an optimised icon set, every icon needs to be semantically as close as possible to the function it visually represents and semantically as far as possible from the other functions represented concurrently. In three experiments (N = 21 each), semantic distances of 19 icons to four menu functions were studied with preference rankings, verbal protocols, and the primed product comparisons method...

CONTEXT: Though critical for improving patient outcomes, palliative care quality indicators are not yet widely used. Better understanding of facilitators and barriers to palliative care quality measurement and improvement might improve their use and program quality. OBJECTIVES: Development of a survey tool to assess palliative care team perspectives on facilitators and barriers to quality measurement and improvement in palliative care programs. METHODS: We used the adapted Consolidated Framework for Implementation Research to define domains and constructs to select instruments...

AIM: Adaptive functioning develops throughout early childhood, and its limitation is a reflection that the child has developmental or emotional problems or even mental retardation. Little is known about the adaptive functioning or developmental status of slum children. The present cross-sectional study was undertaken during the year 2014 to assess the status of adaptive functioning among girl children aged between 3 and 9 years residing in slum areas of Bhubaneswar and to explore the factors associated with poor adaptive functioning...
