BACKGROUND: The minimum clinically important difference (MCID) is used to interpret the clinical relevance of results reported by trials and meta-analyses as well as to plan sample sizes in new studies. However, there is a lack of consensus about the size of MCID in acute pain, which is a core symptom affecting patients across many clinical conditions. METHODS: We identified and systematically reviewed empirical studies of MCID in acute pain. We searched PubMed, EMBASE and Cochrane Library, and included prospective studies determining MCID using a patient-reported anchor and a one-dimensional pain scale (e...

BACKGROUND: Obstructive sleep apnea (OSA) is a public health problem. Detailed analysis of the para-pharyngeal fat pads can help us to understand the pathogenesis of OSA and may mediate the intervention of this sleeping disorder. A reliable and automatic para-pharyngeal fat pads segmentation technique plays a vital role in investigating larger data bases to identify the anatomic risk factors for the OSA. METHODS: Our research aims to develop a context-based automatic segmentation algorithm to delineate the fat pads from magnetic resonance images in a population-based study...

BACKGROUND: Negative mental imagery is ubiquitous in cognitive models of social anxiety and in the social anxiety literature. Previous research has shown that it is causal of increased anxiety, lower social performance ratings and lower implicit self-esteem. Despite its prevalence, few studies have investigated this imagery directly. AIMS: This study aimed to provide an in-depth analysis of the phenomenology of negative imagery experienced by socially anxious individuals, and to compare recurrent and intrusive images with images deliberately generated by participants during the study...

BACKGROUND: Latinos are the largest minority group in the United States, and in California they outnumber non-Hispanic whites. Smoking cessation programs tailored for Latino culture, and this population's specific smoking patterns, are needed. Online social networks for smoking cessation have high potential for Latinos, but have not been tested to date. OBJECTIVE: Building a research program on social media apps for cancer prevention in diverse populations, this qualitative study assessed acceptability of tobacco treatment that was distributed via social media for Latino smokers...

The ability to introspectively evaluate our experiences to form accurate metacognitive beliefs, or insight, is an essential component of decision-making. Previous research suggests individuals vary substantially in their level of insight, and that this variation is related to brain volume and function, particularly in the anterior prefrontal cortex (aPFC). However, the neurobiological mechanisms underlying these effects are unclear, as qualitative, macroscopic measures such as brain volume can be related to a variety of microstructural features...

BACKGROUND: Effective clinical supervision is necessary for high-quality care in community-based substance use disorder treatment settings, yet little is known about current supervision practices. Some evidence suggests that supervisors and counselors differ in their experiences of clinical supervision; however, the impact of this misalignment on supervision quality is unclear. Clinical information monitoring systems may support supervision in substance use disorder treatment, but the potential use of these tools must first be explored...

The choroid is the most vascular tissue in the eye and it has been implicated in the pathophysiology of a variety of ocular diseases. A new era of research in the choroid began with the improved ability to visualize this layer and its inner and outer boundaries using spectral domain optical coherence tomography (OCT) with enhanced depth imaging and swept source OCT. The accuracy and precision of qualitative and quan-titative assessments of the choroidal layer support the potential use of OCT-derived choroidal parameters for diagnosis, monitoring of disease progression, planning surgical access, and evaluating treatment response...

: 207 Background: A disproportionate number of late-stage cancer diagnoses occur in rural residents. Paradoxically this population, with an increased need for palliative care, has minimal access to these services. As smartphone and high-speed internet connectivity reaches near universal penetrance across the country, eHealth technologies have the potential to address this palliative care access gap. Oncology Associated Symptoms and Individualized Strategies (OASIS) web-app was developed to provide tailored cancer symptom self-management support and address this gap...

: 61 Background: Soft tissue sarcomas (STS) are a heterogenous group of rare tumors that involve the connective tissue in the body. As with many rare tumors, little is known about the impact of STS on patient well-being. The objective of this review was to understand patient experience and quality of life (QOL) following diagnosis of STS. METHODS: This was a systematic review of English language articles published between 2005-2015 in PubMed/Medline, Embase, PsychINFO, and Evidence-Based Medicine...

Yuanyuan Jia, Ali Gholipour, Zhongshi He, Simon Warfield
In magnetic resonance (MR), hardware limitations, scan time constraints, and patient movement often result in the acquisition of anisotropic 3D MR images with limited spatial resolution in the out-of-plane views. Our goal is to construct an isotropic high-resolution 3D MR image through upsampling and fusion of orthogonal anisotropic input scans. We propose a multi-frame super-resolution (SR) reconstruction technique based on sparse representation of MR images. Our proposed algorithm exploits the correspondence between the high-resolution slices and the low-resolution sections of the orthogonal input scans as well as the self-similarity of each input scan to train pairs of over-complete dictionaries that are used in a sparse land local model to upsample the input scans...

There is a growing discourse worldwide on the impact of the Human Immunodeficiency Virus (HIV) on "at risk youths". In response, five HIV-positive Nigerian adolescent girls were qualitatively investigated in collaboration with a non-governmental organisation (NGO) in Ibadan, an urban settlement in Nigeria in 2013. Using a secondary data analysis from a photo voice component of the research, combined with narratives, we show that participants possess the capacity to overcome their adversities from the effects of HIV infection and remain resilient...

INTRODUCTION: Interpretation of perimetric findings, particularly in children, relies on accurate assessment of test reliability, yet no objective measures of reliability exist for kinetic perimetry. We developed the kinetic perimetry reliability measure (KPRM), a quantitative measure of perimetric test reproducibility/reliability and report here its feasibility and association with subjective assessment of reliability. METHODS: Children aged 5-15 years, without an ophthalmic condition that affects the visual field, were recruited from Moorfields Eye Hospital and underwent Goldmann perimetry as part of a wider research programme on perimetry in children...

OBJECTIVES : Addressing disparities in low back pain care (LBP) is an important yet largely unaddressed issue. One avenue to addressing disparities, recommended by clinical guidelines, is to ensure that LBP information is culturally appropriate. Our objectives were, first, to develop LBP information that was culturally appropriate for Aboriginal Australians living in a rural area and, second, to compare this to traditional information. METHODS : The overall information development process was guided by a "cultural security" framework and included partnerships between Aboriginal/non-Aboriginal investigators, a synthesis of research evidence, and participation of a project steering group consisting of local Aboriginal people...

BACKGROUND: 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. AIMS: The purpose of the present study was to develop a definition and operationalization of the concept of participation of adults with VSPID...

Numerous qualitative and quantitative techniques can be used to test sensory nerves and pain in both research and clinical settings. The current study demonstrates a quantitative sensory testing protocol using techniques to measure tactile sensation and pain threshold for pressure and heat using portable and easily accessed equipment. These techniques and equipment are ideal for new laboratories and clinics where cost is a concern or a limiting factor. We demonstrate measurement techniques for the following: cutaneous mechanical sensitivity on the arms and legs (von-Frey filaments), radiant and contact heat sensitivity (with both threshold and qualitative assessments using the Visual Analog Scale (VAS)), and mechanical pressure sensitivity (algometer, with both threshold and the VAS)...

Pressure injury (PI) prevention has become a key nursing priority that requires clear identification of visual cues representative of PI risk. There is generalized agreement that erythema and skin wetness and/or maceration should be routinely examined by the clinician as part of PI risk assessment. Such an assessment is largely qualitative, deeply reliant on the perception and interpretation of the clinician. Consequently, skin parameters may be misinterpreted, underestimated, or even missed completely. Objective techniques are needed to augment accurate assessment of erythema and skin wetness and/or maceration...

PURPOSE: To present new tools in CERR for Texture Analysis and Visualization. METHOD: (1) Quantitative Image Analysis: We added the ability to compute Haralick texture features based on local neighbourhood. The Texture features depend on many parameters used in their derivation. For example: (a) directionality, (b) quantization of image, (c) patch-size for the neighborhood, (d) handling of the edge voxels within the region of interest, (e) Averaging co-occurance matrix vs texture features for different directions etc...
