Presumptive acute non-compressive nucleus pulposus extrusion in 11 cats: clinical features, diagnostic imaging findings, treatment and outcome
Authors: Taylor-Brown Frances E , De Decker Steven 
Published: September 2015

Objectives The aim of the study was to describe the clinical features, diagnostic imaging findings, treatment and outcome in cats diagnosed with presumptive acute non-compressive nucleus pulposus extrusion. Methods Medical records and imaging studies of cats diagnosed with presumptive acute non-compressive nucleus pulposus extrusion were retrospectively reviewed. Information on long-term outcome was acquired from patient records and from either owners or referring veterinary surgeons via a telephone questionnaire. Results Eleven cats met the inclusion criteria. All cats had a peracute onset of clinical signs, with eight cats experiencing witnessed (n = 6) or suspected (n = 2) external trauma based on imaging findings. Neuroanatomical localisation included C1–C5 (n = 1), T3–L3 (n = 7) and L4–S3 (n = 3) spinal cord segments. MRI revealed acute non-compressive nucleus pulposus extrusions located at C3–C4 (n = 1), T12–T13 (n = 1), T13–L1 (n = 1), L1–L2 (n = 1), L3–L4 (n = 3), L4–L5 (n = 1) and L5–L6 intervertebral disc spaces (n = 3). Treatment included supportive care and 10 cats were discharged with a median hospitalisation time of 10 days (range 3–26 days). One cat was euthanased during hospitalisation owing to complications unrelated to neurological disease. All cats that presented as non-ambulatory regained an ambulatory status with the median time to ambulation of 17 days (range 6–21 days). Overall, the outcome for cats diagnosed with acute non-compressive nucleus pulposus extrusion was successful, with almost 90% returning to ambulation with urinary and faecal continence. Conclusions and relevance The majority of cats diagnosed with acute non-compressive nucleus pulposus extrusion had good outcomes. Acute non-compressive nucleus pulposus extrusion should be considered as a differential diagnosis for cats presenting with peracute onset of spinal cord dysfunction, particularly if there is a clinical history or evidence of trauma.
General practitioners’ anticipated risk of cancer at referral and their attitude to risk taking and to their role as gatekeeper
Authors: Pedersen Anette , Vedsted Peter 
Published: September 2015

Objectives General practitioners have to deal with situations characterized by real but low likelihoods of serious illness. We aimed to investigate variations in general practitioners’ anticipated risk of cancer when referring a patient and associations both with general practitioners’ attitudes to risk taking and with their gatekeeper role. Methods In January 2012, all 835 active general practitioners in the county of Aarhus, Denmark, received a questionnaire including the Physician Reaction to Uncertainty scale, The Tolerance for Ambiguity scale, the Physician Risk Attitude scale and a number of single items assessing anticipated risk of cancer when referring a hypothetical 50-year-old patient, use of intuition and perception of their role as a gatekeeper. Results A total of 568 (68.0%) practitioners completed and returned the questionnaire. The median anticipated risk of cancer was 30% (inter-quartile range: 15%–50%) and the 5%–95% centiles were 5% and 80%. Increasing tolerance for ambiguity was strongly related to a declining anticipated risk of cancer. None of the other risk attitudes were associated with the anticipated risk of cancer at referral. Increased general practitioners’ age was related to increased anticipated risk of cancer when referring (25% for general practitioners under 45 years to 43% for those 60 years or over) but not statistically important. Conclusions General practitioners either overestimate the risk of cancer when referring for suspected cancer or they appear to need to be very sure of the cancer diagnosis before referral. Further, focus on tolerance for ambiguity should be included in the education of general practitioners.

Published: September 2015

Background Supporting self-management is a core response of health care systems globally to the increasing prevalence of long-term conditions. Lack of a comprehensive taxonomy (or classification) of self-management support components hinders characterization and, ultimately, understanding of these frequently complex, multi-component interventions. Objective To develop a comprehensive, descriptive taxonomy of self-management support components. Methods Components were derived from the 969 unique randomized controlled trials described in the 102 systematic reviews and 61 implementation trials, examining 14 diverse long-term conditions included in the Practical Reviews in Self-Management Support (PRISMS) project followed by discussion at an expert stakeholder workshop. The utility of the taxonomy was then tested using a self-management support intervention for cancer survivors. Results The PRISMS taxonomy comprises 14 components that might be used to support self-management (e.g. information about condition/management, provision of equipment, social support), when delivered to someone with a long-term condition or their carer. Overarching dimensions are delivery mode; personnel delivering the support; intervention targeting; and intensity, frequency and duration of the intervention. The taxonomy does not consider the effectiveness or otherwise of the different components or the overarching dimensions. Conclusions The PRISMS taxonomy offers a framework to researchers describing self-management support interventions, to reviewers synthesizing evidence and to developers of health services for people with long-term conditions.

Published: September 2015

Objective It is widely considered that telemedicine can make positive contributions to dental practice. This study aimed to evaluate a cloud-based telemedicine application for screening for oral diseases. Methods A telemedicine system, based on a store-and-forward method, was developed to work as a platform for data storage. An Android application was developed to facilitate entering demographic details and capturing oral photos. As a proof-of-concept, six volunteers were enrolled in a trial to obtain oral images using smartphone cameras. Following an onsite oral examination, images of participants’ teeth were obtained by a trained dental assistant. Oral images were directly uploaded from the smartphone to a cloud-based server via broadband network. The assessments of oral images by offsite dentists were compared with those carried out via face-to-face oral examinations. Results A complete set of 30 oral images was obtained from all six participants. Out of 192 teeth reviewed, the proportion of ungradable teeth was 8%. Sensitivity and specificity of teledental screening were 57% and 100% respectively. The inter-grader agreement estimated for two examination modalities and between two teledental graders was 70% and 62% respectively. Findings indicate that the proposed system for screening of oral diseases can be implemented to provide a valid and reliable alternative to traditional oral screening. Conclusion This study provided evidence that a robust system for store-and-forward screening for dental problems can be developed, and leads to the need for further testing of its robustness to confirm the accuracy and reliability of the teledentistry system.

Published: September 2015

Aim The aim of this review was to determine if photographic examination and subsequent image analysis provides comparable accuracy to visual inspection for the diagnosis of common dental conditions in children and adolescents. Methods We searched the PubMed database for studies that compared diagnostic accuracy of the two inspection techniques. Studies were screened for inclusion and were assessed for quality and risk of bias using the quality assessment of diagnostic accuracy studies tools. Findings were reported according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA). Findings Sixteen studies met the inclusion criteria. Nine of the included studies evaluated dental caries and eight evaluated enamel defects (one study evaluated both conditions). Conclusions Three studies found image analysis to be superior. For the remaining six studies the diagnostic accuracy was comparable. For enamel defects, three studies found image analysis to be superior, two found visual inspection to be superior and three studies reported comparable diagnostic accuracy. Most studies have found at least comparable results between photographic and visual inspection techniques. However, the wide variation in equipment and personnel used for the collection and interpretation of photographic images made it impossible to generalise the results. It remains unclear exactly how effective store-and-forward teledentistry is for the diagnosis of common dental conditions in children.

Published: September 2015

To synthesize findings from previous studies assessing information needs of primary care patients on the Internet and other information sources in a primary care setting. A systematic review of studies was conducted with a comprehensive search in multiple databases including OVID MEDLINE, CINAHL, and Scopus. The most common information needs among patients were information about an illness or medical condition and treatment methods, while the most common information sources were the Internet and patients’ physicians. Overall, patients tend to prefer the Internet for the ease of access to information, while they trust their physicians more for their clinical expertise and experience. Barriers to information access via the Internet include the following: socio-demographic variables such as age, ethnicity, income, education, and occupation; information search skills; and reliability of health information. Conclusion: Further research is warranted to assess how to create accurate and reliable health information sources for both Internet and non-Internet users.
‘This is my story, how I remember it’: In-depth analysis of Dignity Therapy documents from a study of Dignity Therapy for people with early stage dementia
Authors: Johnston Bridget , Lawton Sally , Pringle Jan 
Published: September 2015

Dementia is a progressive condition that impacts on individuals, families and care professionals. Maintaining quality of life through engagement with the person with dementia is an important part of their care. Dignity Therapy is an interactive, psychotherapeutic intervention that uses a trained dignity therapist to guide the person with dementia through an interview that then creates a written legacy called a generativity document. This can provide knowledge to inform care, as the condition progresses. Generativity documents were analysed using framework analysis. Main themes from the analysis were origin of values, essence and affirmation of self, forgiveness and resolution and existentialism/ meaning of life. These themes provide evidence of the type, scope and contribution that information generated from Dignity Therapy can make to the care and support of people with dementia. They provide information about the values, self-identity and the people and events that have been important to them and influenced their lives.
Binding Specificity of Radiolabeled Cyclic Peptide 153Sm-DTPA-c(CGRRAGGSC) to MHCC97-H Human Liver Cancer Cells and its Antitumor Effects in vivo
Authors: Wu Qinghua , He Yujie , Gu Chen , Jiang Jianwei , Zhou Huan , Zhou Shi 
Published: September 2015

Objective: This objective of this study is to investigate the effects of the radiolabeled cyclic peptide 153Sm-DTPA-c(CGRRAGGSC) on MHCC97-H human liver cancer cells in vitro and in vivo. Methods: The protein expression levels were examined by Western blot analysis. Biological activity of 153Sm-DTPA-c(CGRRAGGSC) was assessed with the radioligand binding assay and competitive inhibition experiment. Subcellular localization of the cyclic peptide was observed by fluorescence microscopy. Animals were implanted with MHCC97-H cells and administered with 153Sm-DTPA-c(CGRRAGGSC). Hematoxylin and eosin staining, electron microscopy, and immunohistochemistry were performed to evaluate the effects of 153Sm-DTPA-c(CGRRAGGSC) on implanted tumors. Result: The expression levels of interleukin 11 receptor were significantly elevated, by 2-to 5-fold, in tumor cell lines, especially for MHCC97-H cells. Characterization of 153Sm-DTPA-c(CGRRAGGSC) showed that the biological activity of the cyclic peptide was not altered after labeling, and the radiolabeled cyclic peptide exhibited sufficient binding affinity to interleukin 11 receptor . The cyclic peptide of c(CGRRAGGSC) was mainly distributed in the cytoplasm and on the cell membrane of MHCC97-H cells. The in vivo experiments showed that the tumor growth was significantly inhibited by the treatment of 153Sm-DTPA-c(CGRRAGGSC). The inhibitory effect of 153Sm-DTPA-c(CGRRAGGSC) on tumor growth was further confirmed by Hematoxylin and eosin staining, electron microscopy, and immunohistochemistry. Moreover, the expression levels of interleukin 11 receptor in implanted tumors were significantly decreased in the treatment groups. Conclusion: 153Sm-DTPA-c (CGRRAGGSC) could specifically bind to interleukin 11 receptor on MHCC97-H liver tumor cells, inhibiting the cell proliferation and inducing cellular apoptosis. These findings provide experimental evidence for the development of individual treatment of liver cancers, as well as recurrence and metastasis.
Recruiting and retaining young adults in a weight gain prevention trial: Lessons learned from the CHOICES study
Authors: Moe Stacey G , Lytle Leslie A , Nanney Marilyn S , Linde Jennifer A , Laska Melissa N 
Published: September 2015

Background/Aims: Young adults are at risk of weight gain, but little is known about designing effective weight control trials for young adults or how to recruit and retain participants in these programs. The Choosing Healthy Options in College Environments and Settings (CHOICES) study evaluated the effectiveness of a weight gain prevention intervention for 2-year college students. We describe the methods used to recruit and retain the colleges and their students, describe the sample and discuss recommendations for future studies. Methods: Students were recruited into a 24-month trial of a weight control intervention with assessment periods at baseline, 4-, 12- and 24-month follow-up. Results: We successfully recruited 441 students through partnerships with three 2-year colleges through a variety of campus-based methods. Ultimately, 83.4% of the randomized cohort participated in the 24-month assessment period. Those retained more often were White (p = 0.03) compared to those who dropped out or were lost to follow-up; no other socio-demographic factor (e.g. gender, ethnicity and education), body mass index, body fat, waist circumference or weight status was observed to differ between randomly assigned groups. Conclusion: Two-year colleges and their students are interested in participating in weight-related trials and partnering with universities for research. Researchers must work closely with administrators to identify benefits to their institutions and to resolve student-level barriers to recruitment and retention. Our experiences from the Choosing Healthy Options in College Environments and Settings study should be useful in identifying effective recruitment and retention methods for weight gain prevention trials among young adults.
Anatomic variations of internal jugular vein, inferior petrosal sinus and its confluence pattern: Implications in inferior petrosal sinus catheterization
Authors: Lv Xianli , Wu Zhongxue 
Published: September 2015

Objective The purpose of this study is to describe anatomic variations of the internal jugular vein (IJV), inferior petrosal sinus (IPS) and their confluence pattern and implications in IPS catheterization. The anatomic route of IPS after going out of the cranium and its confluence patterns with IJV and will supply knowledge about typing of IPS-IJV junction. Method A review of the literature was performed. Results There might be different routes for entering the intracranial segment of the IPS and multislice spiral computed tomography (MSCT) is effective in identifying the confluences of the IPS with the IJV and their courses. It is important to find the confluence of IPS with IJV for diagnosis and treatment of intracranial lesions via venous route. Meanwhile, IPS diameter at the confluence can significantly affect success of catheterization. Conclusion The classification and the theory of the development of the caudal end of the IPS may be useful in establishing treatment strategies that involve endovascular manipulation via the IPS.
The role of peer physical activity champions in the workplace: a qualitative study
Authors: Edmunds Sarah , Clow Angela 
Published: September 2015

Aims: Peer health champions have been suggested as an important component of multilevel workplace interventions to promote healthy behaviours such as physical activity (PA). There is accumulating quantitative evidence of their effectiveness but as yet little exploration of why and how champions influence peer behaviour. The current study explores the role of peer physical activity champions (PPACs) in influencing colleagues’ PA behaviour from the perspectives of both champions and colleagues. Methods: Seven months after the introduction of a workplace PA programme in 17 small- and medium-sized enterprises (SMEs), two focus groups were held with PPACs and four with programme participants. Data were analysed using inductive thematic analysis. Results: Three overarching themes were developed: how PPACs encourage PA, valuable PPAC characteristics and sustaining motivation for the PPAC role. Both direct encouragement from PPACs and facilitation of wider PA supportive social networks within the workplace encouraged behaviour change. PA behaviour change is a delicate subject and it was important that PPACs provided enthusiastic and persistent encouragement without seeming judgemental. Being a PA role model was also a valuable characteristic. The PPACs found it satisfying to see positive changes in their colleagues who had become more active. However, colleagues often did not engage in suggested activities and PPACs required resilience to maintain personal motivation for the role despite this. Conclusion: Incorporating PPACs into SME-based PA interventions is acceptable to employees. It is recommended that PPAC training includes suggestions for facilitating social connections between colleagues. Sensitivity is required when initiating and engaging in conversations with colleagues about increasing their PA. Programmes should ensure PPACs themselves are provided with social support, especially from others in the same role, to help sustain motivation for their role. These findings will be useful to health-promotion professionals developing workplace health programmes.
Excellent long-term results with iliac stenting in local anesthesia for post-thrombotic syndrome
Authors: Klitfod Lotte , Just Sven , Foegh Pia , Baekgaard Niels 
Published: September 2015

Background Only 20% of iliac veins will recanalize on anticoagulation (AC) treatment alone and may, therefore, develop venous obstruction after iliofemoral deep venous thrombosis (DVT). A considerable number of these patients will suffer from post-thrombotic syndrome (PTS) leading to impaired quality of life in more than 50%. Endovascular treatment for iliac vein obstruction using stents is known to alleviate PTS symptoms in selected patients. Purpose To report the Danish long-term results of endovascular treatment with iliac stenting. Material and Methods From 2000 to 2013 consecutive patients were evaluated and 19 patients with severe venous claudication were identified and subsequently underwent angioplasty and stenting. AC treatment was prescribed for 6 months, and knee-high class II compression stocking recommended for 1 year. Scheduled follow-up was done in the outpatient clinic at 6 weeks, 3 months, and annually thereafter. Results Nineteen patients, all women, all with left-sided iliac vein obstruction, and all with severe PTS symptoms were included. The median follow-up time was 81 months (range, 1–146 months; mean, 69 months). Primary patency rate of the inserted iliac stent was 89% (17/19) and 16 patients (84 %) had almost or total symptom relief at follow-up. Conclusion Endovascular stenting of iliac obstruction in local anesthesia is minimally invasive and shows excellent long-term outcomes for patients suffering from PTS.
Mitochondrial and Bioenergetic Dysfunction in Trauma-Induced Painful Peripheral Neuropathy

Published: September 2015

Background Mitochondrial dysfunction is observed in various neuropathic pain phenotypes, such as chemotherapy induced neuropathy, diabetic neuropathy, HIV-associated neuropathy, and in Charcot-Marie-Tooth neuropathy. To investigate whether mitochondrial dysfunction is present in trauma-induced painful mononeuropathy, a time-course of mitochondrial function and bioenergetics was characterized in the mouse partial sciatic nerve ligation model. Results Traumatic nerve injury induces increased metabolic indices of the nerve, resulting in increased oxygen consumption and increased glycolysis. Increased metabolic needs of the nerve are concomitant with bioenergetic and mitochondrial dysfunction. Mitochondrial dysfunction is characterized by reduced ATP synthase activity, reduced electron transport chain activity, and increased futile proton cycling. Bioenergetic dysfunction is characterized by reduced glycolytic reserve, reduced glycolytic capacity, and increased non-glycolytic acidification. Conclusion Traumatic peripheral nerve injury induces persistent mitochondrial and bioenergetic dysfunction which implies that pharmacological agents which seek to normalize mitochondrial and bioenergetic dysfunction could be expected to be beneficial for pain treatment. Increases in both glycolytic acidification and non-glycolytic acidification suggest that pH sensitive drugs which preferentially act on acidic tissue will have the ability to preferential act on injured nerves without affecting healthy tissues.
