Ice-Draft Profiling from Bottom-Mounted ADCP Data
Authors: Shcherbina Andrey Y. , Rudnick Daniel L. , Talley Lynne D. 
Published: July 2010

Abstract
The feasibility of ice-draft profiling using an upward-looking bottom-mounted acoustic Doppler current profiler (ADCP) is demonstrated. Ice draft is determined as the difference between the instrument depth, derived from high-accuracy pressure data, and the distance to the lower ice surface, determined by the ADCP echo travel time. Algorithms for the surface range estimate from the water-track echo intensity profiles, data quality control, and correction procedures have been developed. Sources of error in using an ADCP as an ice profiler were investigated using the models of sound signal propagation and reflection. The effects of atmospheric pressure changes, sound speed variation, finite instrument beamwidth, hardware signal processing, instrument tilt, beam misalignment, and vertical sensor offset are quantified. The developed algorithms are tested using the data from the winter-long ADCP deployment on the northwestern shelf of the Okhotsk Sea.
Subintimal Angioplasty for Advanced Lower Extremity Ischemia due to TASC II C and D Lesions of the Superficial Femoral Artery
Authors: Sidhu Ramandeep , Pigott John , Pigott Matthew , Comerota Anthony 
Published: July 2010

Objective: Subintimal angioplasty (SA) has evolved into a viable revascularization procedure for complex lower extremity lesions. Although patency rates are lower than those for autogenous bypass, limb salvage rates are comparable. This study reviewed the 8-year experience of SA in a single center. Methods: Records of patients undergoing SA were reviewed. Clinical presentation and noninvasive exams were used to classify patients. Lesions were categorized by TransAtlantic InterSociety Consensus (TASC) II guidelines. Outcomes included technical success, patency, amputation-free survival, and limb salvage. Results: 120 patients with TASC II C/D lesions underwent SA. Technical success was 91%. Primary patency at 6 and 12 months was 90% and 73%. Secondary patency at 6 and 12 months was 94% and 85%. One-year amputation-free survival was 90%. One-year limb salvage was 98%. Conclusions: SA for TASC C/D lesions is a safe procedure and may be considered an alternative to bypass, especially in high-risk patients.

Published: July 2010

Objective: To examine the relationship between autonomous motivation and diabetes self-care activities among individuals with diabetes. Methods: Seventy-seven individuals recruited from outpatient clinic registries (64% female, 77% Caucasian, mean age 63 years) completed measures of diabetes-related self-care (Summary of Diabetes Self-care Activities), motivation (Treatment Self-regulation Questionnaire), health literacy (Rapid Estimate of Adult Literacy in Medicine, Newest Vital Sign), health (SF-36v2), social support (Social Support Survey) and self-efficacy (Perceived Competence Scale). Results: Autonomous motivation was the only variable significantly associated with maintaining diet (p<0.0001) and blood glucose testing (p<0.04) in regression analyses. No significant associations were identified for exercise. The variable of age approached significance (p = 0.06), with older individuals being less likely to have exercised in the past week. Discussion: Individuals in this study had difficulty in maintaining self-care demands, especially exercise. Meeting recommended levels of self-care activity was challenging, even for patients with adequate levels of health literacy. Individuals with higher levels of autonomous motivation reported higher frequencies for maintaining diet and testing blood glucose, however, which supports the utility of Self-Determination Theory in promoting diabetes self-care.
Knee Cartilage Defect Patients Enrolled in Randomized Controlled Trials Are Not Representative of Patients in Orthopedic Practice
Authors: Engen C.N. , Engebretsen L. , Årøen A. 
Published: July 2010

Objective: Knee cartilage defects represent a socioeconomic burden and may cause lifelong disability. Studies have shown that cartilage defects are detected in approximately 60% of knee arthroscopies. In clinical trials, the majority of these patients are excluded. This study investigates whether patients included in randomized controlled trials (RCTs) represent a selected group compared to general cartilage patients. Design: Published randomized clinical trials on cartilage repair studies were identified (May 2009) and analyzed to define common inclusion criteria that in turn were applied to all patients submitted to our cartilage repair center during 2008. Patient-administered Lysholm knee score was used to evaluate functional level at referral. In addition, previous surgery and size and localization of cartilage defects were recorded. Results: Common inclusion criteria in the referred patients and patients included in the published RCTs were single femoral condyle lesion, age range 18 to 40 years, and size of lesion range 3.2 to 4.0 cm2. Six of 137 referred patients matched all the 7 RCTs. Previous cartilage repair and multiple lesions were associated with decreased Lysholm score ( P < 0.002). Lysholm score was independent of age, gender, and time of symptoms from the defect. Conclusion: The heterogeneity of the referred cartilage patients and the variation in inclusion criteria in the RCTs may question whether RCTs actually represent the general cartilage patients. The present study suggests that results from published RCTs may not be representative of the gross cartilage population.
Bag1 directly routes immature BCR-ABL for proteasomal degradation
Authors: Tsukahara Fujiko , Maru Yoshiro 
Published: July 2010

Abstract
Degradation of BCR-ABL oncoproteins by heat shock protein 90 (Hsp90) inhibitors in chronic myelogenous leukemia is expected to overcome resistance to ABL tyrosine kinase inhibitors. However, the precise mechanisms still remain to be uncovered. We found that while c-Cbl E3 ligase induced ubiquitin-dependent degradation of mature and phosphorylated BCR-ABL proteins, another E3 ligase CHIP (carboxyl terminus of the Hsc70-interacting protein) degraded immature BCR-ABL proteins and efficiently suppressed BCR-ABL–dependent leukemic growth. Interestingly, Bag1 (Bcl-2-associated athanogene-1), a nucleotide exchange factor for Hsc70, directly bound BCR-ABL with a high affinity, which was enhanced by CHIP and Hsp90 inhibitors, inhibited by imatinib and competed with Hsc70. Bag1 knockdown abrogated Hsp90 inhibitor-induced BCR-ABL degradation. Bag1 induced binding of immature BCR-ABL to proteasome. Expression of Bag1 induced BCR-ABL degradation and growth suppression in Ba/F3 cells when Hsc70 was knocked down with or without CHIP induction. CHIP appears to sort newly synthesized Hsp90-unchaperoned BCR-ABL to the proteasome not only by inhibiting Hsc70 and thereby promoting Bag1 to bind BCR-ABL, but also by ubiquitinating BCR-ABL. Bag1 may direct CHIP/Hsc70-regulated protein triage decisions on BCR-ABL immediately after translation to the degradation pathway.
A meta-analysis for the effect of prophylactic GTN on the incidence of post-ERCP pancreatitis and on the successful rate of cannulation of bile ducts
Authors: Chen Bin , Fan Tao , Wang Chun-hui 
Published: July 2010

Abstract

Background
Glyceryl trinitrate (GTN) has been shown to be able to relax the sphincter of Oddi (SO) both in animals and humans. Theoretically, the use of these compounds during and after endoscopic retrograde cholangiopancreatgraphy (ERCP) could relax the biliary and pancreatic sphincters, facilitating cannulation of common bile duct (CBD) during the procedure, or minimizing potential pancreatic outflow obstruction after the procedure. However, clinical trials evaluating the protective effect of GTN on the post-endoscopic retrograde cholangiopancreatgraphy pancreatitis (PEP) have yielded inconclusive results. This meta-analysis is to systematically assess the effect of prophylactic administration of glyceryl trinitrate (GTN) on the prevention of PEP and the effect on the cannulation of bile ducts.

Methods
By searching PubMed (1966 to September 2009), CENTRAL (Cochrane Controlled trials Register; issue 3, 2009) and EMBASE.com (1984 to September 2009), two independent reviewers systematically identified prospective randomized controlled trials (RCTs) detecting the effect of prophylactic GTN on the incidence of PEP and on the cannulation of bile ducts. A meta-analysis of these clinical trials was then performed.

Results
There are 55/899(6.1%) patients suffering PEP in the treatment group versus 95/915(10.4%) patients in the placebo group. The overall pooled risk of PEP was significantly lower in the GTN group than in the placebo group (OR 0.56, 95% CI: 0.40 to 0.79, p = 0.001). Subgroup analyses suggested that GTN administered by the sublingual form (OR 0.34,95% CI:0.16 to 0.75, p = 0.007) is more effective than transdermal route(OR 0.64,95% CI:0.40 to 1.01, p = 0.05), and the protective effect of GTN was far more obvious in the centers with high incidence of PEP (OR 0.40, 95% CI:0.24 to 0.67, p = 0.0006) than those centers with a low incidence of PEP (OR 0.75, 95% CI: 0.47 to 1.20, p = 0.22). Additionally, the meta-analysis suggests that GTN was not helpful for the cannulation of bile ducts.

Conclusion
We concluded that prophylactic administration of GTN may significantly reduce the incidence of PEP and not be helpful for the cannulation of bile ducts.
Characterization of Two Runx1-Dependent Nociceptor Differentiation Programs Necessary for Inflammatory versus Neuropathic Pain
Authors: Samad Omar Abdel , Liu Yang , Yang Fu-Chia , Kramer Ina , Arber Silvia , Ma Qiufu 
Published: July 2010

Background: The cellular and molecular programs that control specific types of pain are poorly understood. We reported previously that the runt domain transcription factor Runx1 is initially expressed in most nociceptors and controls sensory neuron phenotypes necessary for inflammatory and neuropathic pain. Results: Here we show that expression of Runx1-dependent ion channels and receptors is distributed into two nociceptor populations that are distinguished by persistent or transient Runx1 expression. Conditional mutation of Runx1 at perinatal stages leads to preferential impairment of Runx1-persistent nociceptors and a selective defect in inflammatory pain. Conversely, constitutive Runx1 expression in Runx1-transient nociceptors leads to an impairment of Runx1-transient nociceptors and a selective deficit in neuropathic pain. Notably, the subdivision of Runx1-persistent and Runx1-transient nociceptors does not follow the classical nociceptor subdivision into IB4+ nonpeptidergic and IB4- peptidergic populations. Conclusion: Altogether, we have uncovered two distinct Runx1-dependent nociceptor differentiation programs that are permissive for inflammatory versus neuropathic pain. These studies lend support to a transcription factor-based distinction of neuronal classes necessary for inflammatory versus neuropathic pain.
The surgical management of metastatic epidural compression of the spinal cord
Authors: Quraishi N. A. , Gokaslan Z. L. , Boriani S. 
Published: July 2010

Metastatic epidural compression of the spinal cord is a significant source of morbidity in patients with systemic cancer. With improved oncological treatment, survival in these patients is improving and metastatic cord compression is encountered increasingly often. The treatment is mostly palliative. Surgical management involves early circumferential decompression of the cord with concomitant stabilisation of the spine. Patients with radiosensitive tumours without cord compression benefit from radiotherapy. Spinal stereotactic radiosurgery and minimally invasive techniques, such as vertebroplasty and kyphoplasty, with or without radiofrequency ablation, are promising options for treatment and are beginning to be used in selected patients with spinal metastases. In this paper we review the surgical management of patients with metastatic epidural spinal cord compression.
Mapping the strain distribution on the proximal femur with titanium and flexible-stemmed implants using digital image correlation
Authors: Tayton E. , Evans S. , O’Doherty D. 
Published: July 2010

We implanted titanium and carbon fibre-reinforced plastic (CFRP) femoral prostheses of the same dimensions into five prosthetic femora. An abductor jig was attached and a 1 kN load applied. This was repeated with five control femora. Digital image correlation was used to give a detailed two-dimensional strain map of the medial cortex of the proximal femur. Both implants caused stress shielding around the calcar. Distally, the titanium implant showed stress shielding, whereas the CFRP prosthesis did not produce a strain pattern which was statistically different from the controls. There was a reduction in strain beyond the tip of both the implants. This investigation indicates that use of the CFRP stem should avoid stress shielding in total hip replacement.
Does diabetes affect outcome after arthroscopic repair of the rotator cuff?
Authors: Clement N. D. , Hallett A. , MacDonald D. , Howie C. , McBirnie J. 
Published: July 2010

We compared the outcome of arthroscopic repair of the rotator cuff in 32 diabetic patients with the outcome in 32 non-diabetic patients matched for age, gender, size of tear and comorbidities. The Constant-Murley score improved from a mean of 49.2 (24 to 80) pre-operatively to 60.8 (34 to 95) post-operatively (p = 0.0006) in the diabetic patients, and from 46.4 (23 to 90) pre-operatively to 65.2 (25 to 100) post-operatively (p = 0.0003) in the non-diabetic patients at six months. This was significantly greater (p = 0.0002) in non-diabetic patients (18.8) than in diabetics (11.6). There was no significant change in the mean mental component of the Short-Form 12, but the mean physical component increased from 35 to 41 in non-diabetics (p = 0.0001), and from 37 to 39 (p = 0.15) in diabetics. These trends were observed at one year. Patients with diabetes showed improvement of pain and function following arthroscopic rotator cuff repair in the short term, but less than their non-diabetic counterparts.
Capsuloligamentotaxis and definitive fixation by an ankle-spanning Ilizarov fixator in high-energy pilon fractures

Published: July 2010

Open reduction and internal fixation of high-energy pilon fractures are often associated with serious complications. Various methods have been used to treat these injuries, with variable results. A total of 17 consecutive patients with pilon fractures of AO/OTA type 43-B3 (n = 1), type C2 (n = 12) and type C3 (n = 4) were treated by indirect reduction by capsuloligamentotaxis and stabilisation using an ankle-spanning Ilizarov fixator. The calcaneal ring was removed at a mean of 3.7 weeks (3 to 6). A total of 16 patients were available for follow-up at a mean of 29 months (23 to 43). The mean time to healing was 15.8 weeks (13 to 23). Nine patients had pin-track infections but none had deep infection or osteomyelitis. Four patients (25%) had malunion. Fair, good or excellent ankle scores were found in 14 patients. External fixation with a ring fixator achieves stable reduction of the fractured fragments without additional trauma to soft tissues. With minimum complications and good healing results, the Ilizarov apparatus is particularly useful for high-energy pilon fractures.

Disarticulation of the hip in patients with high-grade tumours in the upper thigh results in significant morbidity. In patients with no disease of the proximal soft tissue a femoral stump may be preserved, leaving a fulcrum for movement and weight-bearing. We reviewed nine patients in whom the oncological decision would normally be to disarticulate, but who were treated by implantation of an endoprosthesis in order to create a functioning femoral stump. The surgery was undertaken for chondrosarcoma in four patients, pleomorphic sarcoma in three, osteosarcoma in one and fibrous dysplasia in one. At follow-up at a mean of 80 months (34 to 132), seven patients were alive and free from disease, one had died from lung metastases and another from a myocardial infarction. The mean functional outcome assessment was 50 (musculoskeletal tumor society), 50 and 60 (physical and mental Short-form 36 scores). Implantation of an endoprosthesis into the stump in carefully selected patients allows fitting of an above-knee prosthesis and improves wellbeing and the functional outcome.
Factors affecting the incidence of infection in hip and knee replacement
Authors: Willis-Owen C. A. , Konyves A. , Martin D. K. 
Published: July 2010

Infection remains a significant and common complication after joint replacement and there is debate about which contributing factors are important. Few studies have investigated the effect of the operating time on infection. We collected data prospectively from 5277 hip and knee replacements which included the type of procedure, the operating time, the use of drains, the operating theatre, surgeon, age and gender. In a subgroup of 3449 knee replacements further analysis was carried out using the tourniquet time in place of the operating time. These variables were assessed by the use of generalised linear modelling against superficial, deep or joint-space post-operative infection as defined by the Australian Surgical-Site Infection criteria. The overall infection rate was 0.98%. In the replacement data set both male gender (z = 3.097, p = 0.00195) and prolonged operating time (z = 4.325, p < 0.001) were predictive of infection. In the knee subgroup male gender (z = 2.250, p = 0.02447), a longer tourniquet time (z = 2.867, p = 0.00414) and total knee replacement (versus unicompartmental knee replacement) (z = −2.052, p = 0.0420) were predictive of infection. These findings support the view that a prolonged operating time and male gender are associated with an increased incidence of infection. Steps to minimise intra-operative delay should be instigated, and care should be exercised when introducing measures which prolong the duration of joint replacement.

FDI and Domestic Investment: An Industry-Level View
Authors: Arndt Christian , Buch Claudia M , Schnitzer Monika E 
Published: July 2010

Abstract
Previous empirical work on the link between domestic and foreign investment has provided mixed results. This may partly be due to the level of aggregation of the data. In this paper, we argue that the impact of FDI on the domestic capital stock depends on the structure of industries. Using industry-level data on the stock of German FDI, we test our predictions. We use panel cointegration methods which address the potential endogeneity of FDI. We find evidence for a positive long-run impact of FDI on the domestic capital stock.
An optimal iteration method with application to the Thomas-Fermi equation
Authors: Marinca Vasile , Herişanu Nicolae 
Published: July 2010

Abstract
The aim of this paper is to introduce a new approximate method, namely the Optimal Parametric Iteration Method (OPIM) to provide an analytical approximate solution to Thomas-Fermi equation. This new iteration approach provides us with a convenient way to optimally control the convergence of the approximate solution. A good agreement between the obtained solution and some well-known results has been demonstrated. The proposed technique can be easily applied to handle other strongly nonlinear problems.

Published: July 2010

Abstract
Familial Mediterranean fever (FMF) is a disease of unknown etiology characterized by recurrent attacks of polyserositis and fever. Intercellular adhesion molecule-1 (ICAM-1) is known to contribute inflammatory conditions by regulating leukocyte localization at inflammatory sites. The aim of this study was to evaluate the probable association of ICAM-1 G/R 241 and ICAM-1 E/K 469 polymorphisms according to susceptibility with FMF. Sixty-seven FMF patients and 83 healthy volunteers were included in the study. Genomic DNA was extracted from EDTA-preserved whole blood of whole series of patients and controls, and genotyped by polymerase chain reaction (PCR) and allele-specific oligonucleotide techniques for ICAM-1 polymorphisms G/R at codon 241 and E/K at codon 469. The ICAM-1 241 genotype and allele frequencies of FMF patients and healthy volunteers were similar. The frequency of ICAM-1 K469 homozygosity was significantly lower in FMF patients than in the controls (32.8% vs 50.7% subsequently, p=0.03). Moreover, ICAM-1 E469 allele was more frequent in FMF patients than in controls (44.8% vs 32.3%, p:0.03). Our results showed that ICAM-1 469 gene polymorphism could contribute to the pathogenesis of FMF.
