Purpose: Poorly controlled pain is common in advanced cancer. The objective of this article was to synthesize the evidence on the effectiveness of pain-focused interventions in this population. Methods: We searched MEDLINE, CINAHL, PsycINFO, Cochrane, and DARE from 2000 through December 2011. We included prospective, controlled health care intervention studies in advanced cancer populations, focusing on pain. Results: Nineteen studies met the inclusion criteria; most focused on nurse-led patient-centered interventions. In all, 9 (47%) of the 19 studies found a significant effect on pain. The most common intervention type was patient/caregiver education, in 17 (89%) of 19 studies, 7 of which demonstrated a significant decrease in pain. Conclusions: We found moderate strength of evidence that pain in advanced cancer can be improved using health care interventions, particularly nurse-led patient-centered interventions.
Initial Assessment of Patients Without Cognitive Failure Admitted in Palliative Care
Authors: Gonçalves Ferraz 
Published: February 2013

Aim: To develop a screening tool that was short, not time consuming but able to detect the patients’ main problems at admission. Methods: A list of 106 symptoms/problems derived from a review of the literature was created and shortened using a Delphi process. Results: Thirteen experts scored each item with a numeric rating scale of 0 to 10 for relevance. After 3 rounds, the list was shortened to 14 items: general question—what bothers you the most? symptoms/problems—pain, lack of appetite, vomiting, tiredness/fatigue, nausea, constipation, shortness of breath, depression, anxiety, difficulty sleeping; activity (dressing, washing, etc); support from family/friends; and well-being. Conclusion: The final tool is short and seems to include the relevant items that would make it useful for clinical practice.
Metatarsal Head Resurfacing for Advanced Hallux Rigidus
Authors: Kline Alex J. , Hasselman Carl T. 
Published: February 2013

Background: Advanced stages of first metatarsophalangeal (MTP) arthritis have traditionally been treated with various arthroplasties or arthrodesis. Studies suggest the outcomes of arthrodesis are superior to those of metallic joint replacement; however, complications and suboptimal outcomes in active patients still remain with arthrodesis of the first MTP joint. This study reports results of patients with advanced MTP arthritis who underwent metallic resurfacing of the metatarsal side of the MTP joint. Methods: From 2005 to 2006, 26 patients (30 implants) with stage II or III hallux rigidus underwent resurfacing with the HemiCAP® implant and consented to participate in a study comparing pre- and postoperative radiographs, range of motion (ROM), American Orthopedic Foot and Ankle Society, and Short Form 36 Health Survey (SF-36) scores. Average age of these patients was 51 years. Patients were assessed at a mean of 27 months with outcome measures and contacted at 60 months to assess current symptoms and satisfaction. Results: Assessment at 27 months demonstrated statistically significant improvements in ROM, AOFAS, and SF-36 scores ( P < .05) when compared to baseline. Mean preoperative AOFAS scores improved from 51.5 to 94.1. Mean active ROM improved from 19.7 to 47.9 degrees. Mean passive ROM improved from 28.0 to 66.3 degrees. Mean RAND SF-36 physical component score improved significantly from 66.7 to 90.6. Average time for return to work was 7 days. At 60 months, all patients reported excellent satisfaction with their current state and would repeat the procedure. Implant survivorship was 87% at 5 years. Of the 30 implants, 4 were revised at 3 years. Conclusion: The results at 5 years were very promising. Preservation of joint motion, alleviation of pain, and functional improvement data were very encouraging. Because minimal joint resection was performed, conversion to arthrodesis or other salvage procedures would be relatively simple if further intervention became necessary. Level of Evidence: Level IV, prospective case series.

Published: February 2013

Background: We aimed to investigate the association between electrocardiographic (ECG) grade III ischemia and angiographic thrombus burden in patients with acute ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (pPCI). Methods: The study population consisted of 307 patients with STEMI. Baseline ECGs of the patients were analyzed for grade III ischemia; angiographic thrombus burden was assessed by thrombolysis in myocardial infarction thrombus classification. Results: A total of 108 (35%) patients had low thrombus burden whereas 199 (65%) patients had high thrombus burden. Grade III ischemia was more prevalent in patients with high thrombus burden (25.1% vs 11.1%, P = .004). Only grade III ischemia (odds ratio: 2.59, 95% confidence interval 1.24-5.39, P = .011) and history of coronary artery disease (CAD) were found to be the independent predictors of high thrombus burden. Conclusion: Grade III ischemia on ECG and previous history of CAD were independent predictors of coronary thrombus burden in patients with STEMI who underwent pPCI.

Published: February 2013

Background: Multiple sclerosis (MS) in Asia is thought to have different clinical characteristics from MS in Western countries; however, previous studies in Asia were performed without properly differentiating neuromyelitis optica (NMO) from MS. Objectives: To evaluate the clinical characteristics of MS in Korea after careful exclusion of potential explanations other than MS, particularly NMO spectrum disorder (NMOSD). Methods: This study is a retrospective review of consecutive MS patients attending five referral hospitals in Korea. All patients’ MS diagnoses were re-evaluated. Results: Of the 105 patients, 70 were female and 35 were male. The mean age of onset was 30.4 years and the mean disease duration was 5.4 years. On initial magnetic resonance imaging (MRI), 58% and 64% fulfilled the criteria for dissemination in space for the 2005 and 2010 McDonald criteria, respectively. Spinal cord lesions were observed in 78% of patients, primarily present as multiple small lesions with a mean length of 0.9 vertebral segments. The median time from disease onset to an Expanded Disability Status Scale 6 was 20 years. Conclusions: After careful exclusion of NMOSD, we found that the clinical pattern of MS in Korea does not fundamentally differ from that seen in Western countries.
An automatic visual analysis system for tennis
Authors: Connaghan Damien , Moran Kieran , O’Connor Noel E 
Published: February 2013

This article presents a novel video analysis system for coaching tennis players of all levels, which uses computer vision algorithms to automatically edit and index tennis videos into meaningful annotations. Existing tennis coaching software lacks the ability to automatically index a tennis match into key events, and therefore, a coach who uses existing software is burdened with time-consuming manual video editing. This work aims to explore the effectiveness of a system to automatically detect tennis events. A secondary aim of this work is to explore the benefits coaches experience in using an event retrieval system to retrieve the automatically indexed events. It was found that automatic event detection can significantly improve the experience of using video feedback as part of an instructional coaching session. In addition to the automatic detection of key tennis events, player and ball movements are automatically tracked throughout an entire match and this wealth of data allows users to find interesting patterns in play. Player and ball movement information are integrated with the automatically detected tennis events, and coaches can query the data to retrieve relevant key points during a match or analyse player patterns that need attention. This coaching software system allows coaches to build advanced queries, which cannot be facilitated with existing video coaching solutions, without tedious manual indexing. This article proves that the event detection algorithms in this work can detect the main events in tennis with an average precision and recall of 0.84 and 0.86, respectively, and can typically eliminate manual indexing of key tennis events.

Published: February 2013

Objective To characterize the immunolocalization of clusterin in the repair cartilage of patients having undergone autologous chondrocyte implantation (ACI) and evaluate correlation to clinical outcome. Design Full-depth core biopsies of repair tissue were obtained from 38 patients who had undergone ACI at an average of 18 ± 13 months previously (range 8-67 months). The biopsies were snap frozen, cryosectioned, and clusterin production immunolocalized using a specific monoclonal clusterin antibody and compared with normal and osteoarthritic cartilage. Clinical outcome was assessed from patients preoperatively, at the time of biopsy, and annually postoperatively. Results Intensity of immunostaining for clusterin decreased with age in healthy cartilage tissue. Clusterin was detected to a variable degree in 37 of the 38 ACI cartilage biopsies, in single and clustered chondrocytes, in the pericellular capsule and the cartilage extracellular matrix, as well as the osteocytes and osteoid within the bone. Chondrocytes in hyaline repair tissue were significantly more immunopositive than those in fibrocartilage repair tissue. Clinical outcome improved significantly post-ACI, but did not correlate with the presence of clusterin in the repair tissue. Conclusions These results demonstrate the presence of clusterin in actively repairing human cartilage and indicate a different distribution of clusterin in this tissue compared to normal cartilage. Variability in clusterin staining in the repair tissue could indicate different states of chondrogenic differentiation. The clinical significance of clusterin within repair tissue is difficult to assess, although the ideal functioning repair tissue morphology should resemble that of healthy adult cartilage.

Key PointsTwo distinct proximal signaling complexes involving SLP-76 and LAT1/LAT2 or ADAP are formed by immunoreceptor-activated NK cells. Both signaling pathways formed by LAT1/LAT2 and ADAP with SLP-76 are required for the optimal functioning of immunoreceptor-activated NK cells.
Epigenetics of hypoxic pulmonary arterial hypertension following intrauterine growth retardation rat: epigenetics in PAH following IUGR
Authors: Xu Xue-Feng , Lv Ying , Gu Wei-Zhong , Tang Li-Li , Wei Jia-Kai , Zhang Li-Yan , Du Li-Zhong 
Published: February 2013

Abstract

Background
Accumulating evidence reveals that intrauterine growth retardation (IUGR) can cause varying degrees of pulmonary arterial hypertension (PAH) later in life. Moreover, epigenetics plays an important role in the fetal origin of adult disease. The goal of this study was to investigate the role of epigenetics in the development of PAH following IUGR.

Methods
The IUGR rats were established by maternal undernutrition during pregnancy. Pulmonary vascular endothelial cells (PVEC) were isolated from the rat lungs by magnetic-activated cell sorting (MACS). We investigated epigenetic regulation of the endothelin-1 (ET-1) gene in PVEC of 1-day and 6-week IUGR rats, and response of IUGR rats to hypoxia.

Results
The maternal nutrient restriction increased the histone acetylation and hypoxia inducible factor-1α (HIF-1α) binding levels in the ET-1 gene promoter of PVEC in IUGR newborn rats, and continued up to 6 weeks after birth. These epigenetic changes could result in an IUGR rat being highly sensitive to hypoxia later in life, causing more significant PAH or pulmonary vascular remodeling.

Conclusions
These findings suggest that epigenetics is closely associated with the development of hypoxic PAH following IUGR, further providing a new insight for improved prevention and treatment of IUGR-related PAH.

Published: February 2013

Abstract

Background
Gene Ontology (GO) enrichment analysis remains one of the most common methods for hypothesis generation from high throughput datasets. However, we believe that researchers strive to test other hypotheses that fall outside of GO. Here, we developed and evaluated a tool for hypothesis generation from gene or protein lists using ontological concepts present in manually curated text that describes those genes and proteins.

Results
As a consequence we have developed the method Statistical Tracking of Ontological Phrases (STOP) that expands the realm of testable hypotheses in gene set enrichment analyses by integrating automated annotations of genes to terms from over 200 biomedical ontologies. While not as precise as manually curated terms, we find that the additional enriched concepts have value when coupled with traditional enrichment analyses using curated terms.

Conclusion
Multiple ontologies have been developed for gene and protein annotation, by using a dataset of both manually curated GO terms and automatically recognized concepts from curated text we can expand the realm of hypotheses that can be discovered. The web application STOP is available at http://mooneygroup.org/stop/.

Published: February 2013

Abstract

Background
Interstitial lung disease (ILD) is frequently associated with collagen diseases. The prognosis of acute-onset diffuse ILD (AoDILD) occurring in collagen disease patients is very poor. Here, we investigated serum biomarker profiles of AoDILD to find markers predicting outcome in patients with collagen diseases.

Methods
A solid-phase antibody array was used for screening 274 biomarkers in pooled sera from collagen disease patients in the AoDILD state and in the stable state. Biomarkers in individual sera were detected without pooling by bead-based immunoassay.

Results
The serum levels of matrix metalloproteinase (MMP)-1, tissue inhibitor of metalloproteinase (TIMP)-1, osteopontin, interleukin (IL)-2 receptor α(IL-2Rα), and IL-1 receptor antagonist were significantly increased in AoDILD, but TIMP-2, MMP-3, and eotaxin 2 levels were decreased. The MMP-3 to MMP-1 ratio was reduced in AoDILD state. This tendency was also observed in RA patients with AoDILD. Moreover, serum IL-6 level was significantly increased in the AoDILD state in patients with acute exacerbation of ILD (AE-ILD). Serum TIMP-1 and IL-2Rα levels were significantly increased in the AoDILD state in patients with drug-induced ILD (DI-ILD), whereas TIMP-2, MMP-3, and eotaxin 2 levels were decreased. The MMP-3 to MMP-1 ratio was reduced in AoDILD state in patients with DI-ILD. The serum TIMP-3,MMP-9, osteopontin, IL-2Rα, MMP-1, and MMP-8 levels were significantly increased in the AoDILD state in patients who subsequently died, whereas TIMP-2 and MMP-3 levels were decreased in those who survived. The MMP-3 to MMP-1 ratio was reduced in AoDILD state in patients who died, but not in those who survived.

Conclusions
Serum biomarker profiles could represent prognosis markers for AoDILD in collagen diseases.
Systematic and quantitative mRNA expression analysis of TRP channel genes at the single trigeminal and dorsal root ganglion level in mouse
Authors: Vandewauw Ine , Owsianik Grzegorz , Voets Thomas 
Published: February 2013

Abstract

Background
Somatosensory nerve fibres arising from cell bodies within the trigeminal ganglia (TG) in the head and from a string of dorsal root ganglia (DRG) located lateral to the spinal cord convey endogenous and environmental stimuli to the central nervous system. Although several members of the transient receptor potential (TRP) superfamily of cation channels have been implicated in somatosensation, the expression levels of TRP channel genes in the individual sensory ganglia have never been systematically studied.

Results
Here, we used quantitative real-time PCR to analyse and compare mRNA expression of all TRP channels in TG and individual DRGs from 27 anatomically defined segments of the spinal cord of the mouse. At the mRNA level, 17 of the 28 TRP channel genes, TRPA1, TRPC1, TRPC3, TRPC4, TRPC5, TRPM2, TRPM3, TRPM4, TRPM5, TRPM6, TRPM7, TRPM8, TRPV1, TRPV2, TRPV4, TRPML1 and TRPP2, were detectable in every tested ganglion. Notably, four TRP channels, TRPC4, TRPM4, TRPM8 and TRPV1, showed statistically significant variation in mRNA levels between DRGs from different segments, suggesting ganglion-specific regulation of TRP channel gene expression. These ganglion-to-ganglion differences in TRP channel transcript levels may contribute to the variability in sensory responses in functional studies.

Conclusions
We developed, compared and refined techniques to quantitatively analyse the relative mRNA expression of all TRP channel genes at the single ganglion level. This study also provides for the first time a comparative mRNA distribution profile in TG and DRG along the entire vertebral column for the mammalian TRP channel family.

Published: February 2013

Abstract

Background
Diabetes mellitus type 2 (DM2) is highly associated with increased risk for chronic kidney disease (CKD), end stage renal disease (ESRD) and cardiovascular morbidity. Epidemiological and genetic studies generate hypotheses for innovative strategies in DM2 management by unravelling novel mechanisms of diabetes complications, which is essential for future intervention trials. We have thus initiated the DIAbetes COhoRtE study (DIACORE).

Methods
DIACORE is a prospective cohort study aiming to recruit 6000 patients of self-reported Caucasian ethnicity with prevalent DM2 for at least 10 years of follow-up. Study visits are performed in University-based recruiting clinics in Germany using standard operating procedures. All prevalent DM2 patients in outpatient clinics surrounding the recruiting centers are invited to participate. At baseline and at each 2-year follow-up examination, patients are subjected to a core phenotyping protocol. This includes a standardized online questionnaire and physical examination to determine incident micro- and macrovascular DM2 complications, malignancy and hospitalization, with a primary focus on renal events. Confirmatory outcome information is requested from patient records. Blood samples are obtained for a centrally analyzed standard laboratory panel and for biobanking of aliquots of serum, plasma, urine, mRNA and DNA for future scientific use. A subset of the cohort is subjected to extended phenotyping, e.g. sleep apnea screening, skin autofluorescence measurement, non-mydriatic retinal photography and non-invasive determination of arterial stiffness.

Discussion
DIACORE will enable the prospective evaluation of factors involved in DM2 complication pathogenesis using high-throughput technologies in biosamples and genetic epidemiological studies.

Abstract

Background
Renal failure with following continuous renal replacement therapy is a major clinical problem in liver transplant recipients, with reported incidences of 3% to 20%. Little is known about the significance of postoperative acute renal failure or acute-on-chronic renal failure to postoperative outcome in liver transplant recipients.

Methods
In this post hoc analysis we compared the mortality rates of 135 consecutive liver transplant recipients over 6 years in our center subject to their renal baseline conditions and postoperative RRT. We classified the patients into 4 groups, according to their preoperative calculated Cockcroft formula and the incidence of postoperative renal replacement therapy. Data then were analyzed in regard to mortality rates and in addition to pre- and peritransplant risk factors.

Results
There was a significant difference in ICU mortality (p=.008), hospital mortality (p=.002) and cumulative survival (p<.0001) between the groups. The highest mortality rate occurred in the group with RRT and normal baseline kidney function (20% ICU mortality, 26.6% hospital mortality and 50% cumulative 1-year mortality, respectively). The hazard ratio in this group was 9.6 (CI 3.2-28.6, p=.0001).

Conclusion
This study shows that in liver transplant recipient’s acute renal failure with postoperative RRT is associated with mortality and the mortality rate is higher than in patients with acute-on-chronic renal failure and postoperative renal replacement therapy.
