Abstract
Musculoskeletal pain is a common cause of work absence, and early intervention is advocated to prevent the adverse health and economic consequences of longer-term absence. This cluster randomised controlled trial investigated the effect of introducing a vocational advice service into primary care to provide occupational support. Six general practices were randomised; patients were eligible if they were consulting their general practitioner with musculoskeletal pain and were employed and struggling at work or absent from work <6 months. Practices in the intervention arm could refer patients to a vocational advisor embedded within the practice providing a case-managed stepwise intervention addressing obstacles to working. The primary outcome was number of days off work, over 4 months. Participants in the intervention arm (n = 158) had fewer days work absence compared with the control arm (n = 180) (mean 9.3 [SD 21·7] vs 14·4 [SD 27·7]) days, incidence rate ratio 0·51 (95% confidence interval 0·26, 0·99), P = 0·048). The net societal benefit of the intervention compared with best care was £733: £748 gain (work absence) vs £15 loss (health care costs). The addition of a vocational advice service to best current primary care for patients consulting with musculoskeletal pain led to reduced absence and cost savings for society. If a similar early intervention to the one tested in this trial was implemented widely, it could potentially reduce days absent over 12 months by 16%, equating to an overall societal cost saving of approximately £500 million (US $6 billion) and requiring an investment of only £10 million.

Abstract

Purpose
The aim of this study was to evaluate whether a prolonged detoxification treatment could decrease the relapse rate at 3 months after alcohol cessation in alcohol-dependent individuals through decreasing the levels of postdetoxification craving and anxiety.

Methods
Twenty-six adult patients with alcohol dependence (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision) who began an outpatient alcohol cessation program with an initial drinking goal of abstinence were enrolled in a 3-month, parallel, randomized (1:1 ratio), controlled, open-label, pilot trial. Participants were randomized to receive a detoxification treatment of diazepam with a duration of 30 (n = 12) or 10 days (n = 14). All participants received BRENDA-based psychotherapy during follow-up.

Results
No significant between-group difference in relapse to any drinking was found at 3 months (P = 0.20). However, relapse to any heavy drinking at 3 months and regular drinking or heavy drinking during follow-up were significantly lower in the 30-day diazepam group (P = 0.009, P = 0.049, and P = 0.004, respectively). These differences were corroborated by significant differences in the alcohol-specific biological marker carbohydrate deficient transferrin at 3 months. Participants in the 30-day diazepam group also displayed significantly lower scores for alcohol craving (P = 0.007), self-reported anxiety (P = 0.024), and clinician-assessed anxiety (P = 0.002) throughout the follow-up. No serious adverse event was reported during the study.

Conclusion
This study provides an evidence-based rationale for a double-blind, randomized, placebo-controlled trial to confirm the efficacy of such a procedure on short-term and mid-/long-term drinking outcomes after alcohol cessation in alcohol-dependent individuals.

Objective
The aim of this study was to assess the effect of branched-chain amino acid (BCAA) supplements on muscle strength and muscle mass in patients with liver cirrhosis.

Patients and methods
We carried out a single-center, prospective study of adult cirrhotic patients receiving nutrition therapy at Shonan Kamakura General Hospital. A 28-day pretreatment observation period was followed by a 24-week treatment period. Patients who fulfilled the treatment criteria received one package of oral BCAA supplement powder twice a day and the response was evaluated. A responder to BCAA in muscle strength and muscle mass was defined as a patient with an increased skeletal muscle mass index and hand grip assessed 24 weeks after drug treatment commenced.

Results
Eighty-two patients fulfilled our criteria and completed the treatment. In terms of muscle strength, there were 59 (72.0%) responders to BCAA supplementation with a significant increase in hand grip from before treatment (22.2±6.3 kg) to after treatment (23.9±6.4 kg) (P<0.001). In terms of muscle mass, 36 (43.9%) patients responded to BCAA with a slight decrease in skeletal muscle mass index from before treatment (7.40±1.62) to after treatment (7.30±1.49) (P=0.333).

Conclusion
BCAA supplementation improved low muscle strength in patients with chronic liver disease, but did not increase muscle mass during the treatment period.
Cocaine/levamisole-associated autoimmune syndrome: a disease of neutrophil-mediated autoimmunity
Authors: Cascio Michael J. , Jen Kuang-Yu 
Published: October 2017

Purpose of review
Levamisole was previously used for its immunomodulatory properties to treat rheumatoid arthritis and some cancers. However, because of serious side-effects, it was taken off the market in the United States. Recently, levamisole has reemerged as a popular cocaine adulterant. Some individuals who consume levamisole-adulterated cocaine can develop a life-threatening autoimmune syndrome. In this review, the medical consequences of levamisole exposure and postulated mechanisms by which levamisole induces these adverse effects are discussed.

Recent findings
Although agranulocytosis and cutaneous vasculitis are the major findings in patients who develop cocaine/levamisole-associated autoimmune syndrome (CLAAS), more recent experience indicates that other organ systems can be involved as well. Current studies point to neutrophil activation and neutrophil extracellular trap formation with subsequent antineutrophil cytoplasmic antibody-mediated tissue injury as a possible mechanism of CLAAS.

Summary
In the past decade, the detrimental effects of levamisole have reemerged because of its popularity as a cocaine adulterant. Although infrequent, some individuals develop a systemic autoimmune syndrome characterized by immune-mediated agranulocytosis and antineutrophil cytoplasmic antibody-mediated vasculitis. Mechanistically, neutrophil antigens appear to be a major player in inducing CLAAS. Prompt cessation of levamisole exposure is key to treatment, although relapses are frequent because of the addictive effects of cocaine and the high prevalence of levamisole within the cocaine supply.

Published: October 2017

Objectives
Pancreatic cancer is a highly chemoresistant tumor and underlying mechanisms are not well understood. Sex determining region Y box 9 (Sox9) is a transcription factor playing important roles on maintenance of pluripotent cells during pancreatic organogenesis. The purpose of this study is to evaluate the roles of Sox9 in pancreatic cancer.

Methods
The Sox9 expression was evaluated by immunohistochemical analysis. Effects of Sox9 inhibition by siRNA or shRNA on chemosensitivity, sphere formation, stem cell markers expression, and in vivo tumor formation rate were examined using pancreatic cancer cell lines.

Results
High expression of Sox9 in pancreatic cancer tissue is correlated with poor prognosis (P = 0.011). Cells with high Sox9 expression (PANC-1, Capan-1) showed stronger chemoresistance to Gemcitabine than cells with low Sox9 expression (BxPC-3, MIA PaCa-2). The chemosensitivity in PANC-1 was recovered by suppressing Sox9 using siRNA (P < 0.05). Both sphere formation rate and the proportion of CD44highCD24high cells were decreased by Sox9 inhibition. Tumor formation rate of Tet-on inducible Sox9 shRNA-transfected PANC-1 cells in KSN/Slc nude mice was decreased by induction of shRNA with doxycycline feeding (P < 0.05).

Conclusion
Sox9 plays an important role in chemoresistance by the induction of stemness in pancreatic cancer cells.
PCR-based tests for the early diagnosis of sepsis. Where do we stand?
Authors: Ginn Andrew N. , Halliday Catriona L. , Douglas Abby P. , Chen Sharon C-A. 
Published: October 2017

Purpose of review
Bloodstream infections are a major cause of hospital and ICU admission with high morbidity and mortality; however, early and targeted antimicrobial therapy reduces mortality in high-risk patients. This article focuses on the diagnosis of bloodstream infections by PCR-based approaches at an early stage to enable prompt treatment and prevent organ dysfunction.

Recent findings
PCR systems offering highly multiplexed targeting of bacterial and/or fungal pathogens (in whole blood) offer the best opportunity for clinical impact, as informed decisions can be made within 4–8 h of the blood draw. Although more rapid, these systems are typically associated with lower sensitivity and specificity than postculture detection methods which rely on microbial growth. Additionally, unlike postculture methods, detection directly from blood is not prone to misleading results because of concurrent (or previous) therapy, which limit clinical relevance.

Summary
Rapid and accurate identification of the cause of sepsis is essential in improving patient outcomes. Early identification of these pathogens by nucleic acid detection assays directly from blood samples remains key to achieving this, particularly if taken at the time of presentation. Selection of the most suitable PCR system is typically influenced by local epidemiology and by the resources of the testing laboratory.
Comparison of Unenhanced T1-Weighted Signal Intensities Within the Dentate Nucleus and the Globus Pallidus After Serial Applications of Gadopentetate Dimeglumine Versus Gadobutrol in a Pediatric Population

Published: October 2017

Objective
The aim of this study was to evaluate and compare changes in T1-weighted signal intensity (SI) within the dentate nucleus (DN) and globus pallidus (GP) in a pediatric population after serial applications of the linear gadolinium-based magnetic resonance contrast medium gadopentetate dimeglumine and the more stable macrocyclic agent gadobutrol.

Materials and Methods
Institutional review board approval was obtained. Two similar pediatric patient cohorts who underwent at least 3 serial contrast-enhanced magnetic resonance imaging (MRI) examinations with sole application of gadopentetate dimeglumine or gadobutrol were analyzed. All MRI examinations were performed on a 1.5 T system acquiring unenhanced T1-weighted spin echo sequences, which were evaluated on the baseline MRI and after the contrast medium administrations. For analysis of SI changes in the DN, the ratios of the DN to the pons (P) and to the middle cerebellar peduncle (MCP) were assessed. The GP was compared with the thalamus (TH) by dividing the SIs between GP and TH (GP-to-TH ratio).

Results
Twenty-eight patients (13 boys, 15 girls; mean age, 8.4 ± 6.8 years) who received at least 3 applications of gadopentetate dimeglumine and 25 patients (13 boys, 12 girls; mean age, 9.7 ± 5.4 years) with 3 or more gadobutrol injections were included. After 3 administrations of gadopentetate dimeglumine, the T1-weighted SI ratios significantly increased: mean difference value of 0.036 ± 0.031 (DN-to-P; P < 0.001), 0.034 ± 0.032 (DN-to-MCP; P < 0.001), and 0.025 ± 0.025 (GP-to-TH; P = 0.001). In a subanalysis of 12 patients with more than 3 injections of gadopentetate dimeglumine, the mean differences of the SI ratios were slightly higher: 0.043 ± 0.032 (DN-to-P; P = 0.001), 0.041 ± 0.035 (DN-to-MCP; P = 0.002), and 0.028 ± 0.025 (GP-to-TH; P = 0.003). In contrast, gadobutrol did not show a significant influence on the SI ratios, neither after 3 nor after more than 3 applications.

Conclusions
The T1-weighted SI increase within the DN and GP after serial administrations of the linear contrast medium gadopentetate dimeglumine, but not after serial applications of the macrocyclic agent gadobutrol, found in a pediatric population, is consistent with results published for adult patients. The clinical impact of the intracranial T1-hyperintensities is currently unclear. However, in accordance with the recent decision of the Pharmacovigilance and Risk Assessment Committee of the European Medicines Agency, intravenous macrocyclic agents should be preferred and MR contrast media should be used with caution and awareness of the pediatric brain development in children and adolescents.

Published: October 2017

Objectives
The aims of this study were to prospectively evaluate image quality, duct visibility, and diagnostic performance in duct-related pathologies of compressed-sensing (CS) accelerated 3-dimensional (3D) magnetic resonance cholangiopancreatography (MRCP) prototype protocols and compare these with those of conventional 3D MRCP protocol in patients with suspected pancreatic diseases.

Material and Methods
The institutional review board approved this prospective study and all patients provided written informed consent. A total of 80 patients (47 men and 33 women; median age, 57 years; age range, 24–87 years) underwent 3D MRCP at 3.0 T. Three protocols were performed in each patient in random order: CS breath-hold (BH) protocol, CS navigator-triggered (NT) protocol, and conventional NT protocol. The acquisition time of each protocol was recorded. Image quality and duct visibility were independently rated in random order on a 5-point scale by 2 radiologists, who were blinded to the protocols. Receiver operating characteristic curves were generated, and area under the curve (Az value) was used to compare the diagnostic performance of each protocol in duct-related pathologies.

Results
Acquisition time was 17 seconds for the CS-BH and 134.1 ± 33.5 seconds for the CS-NT protocol, both being significantly shorter than the conventional NT protocol (364.7 ± 78.4 seconds; both P < 0.01). The CS-BH MRCP protocol showed significantly less artifacts compared with the CS-NT and conventional NT protocols (both P < 0.01). Visualization of bile ducts was comparable in all 3 protocols, whereas CS-NT and conventional NT MRCP depicted pancreatic duct better than CS-BH MRCP did (for proximal, middle, and distal segment; all P < 0.05). Compressed-sensing-NT MRCP had the highest diagnostic performance for detecting ductal anomalies, long-segment duct stenosis, abnormal branch ducts, and communication between cystic lesion and pancreatic duct (mean Az value, 0.943–0.983).

Conclusions
Compressed-sensing MRCP is feasible in patients with suspected pancreatic diseases. Compressed-sensing-NT MRCP demonstrated superior diagnostic accuracy for duct-related pathologies.

Published: October 2017

Objective:
The aim of this study was to evaluate the safety and efficacy of elective rectal resection for rectal cancer in adults by robotic surgery compared with conventional laparoscopic surgery.

Summary of Background Data:
Technological advantages of robotic surgery favor precise dissection in narrow spaces. However, the evidence base driving recommendations for the use of robotic surgery in rectal cancer primarily hinges on observational data.

Methods:
We searched MEDLINE, Embase, and CENTRAL for randomized controlled trials (until August 2016) comparing robotic surgery versus conventional laparoscopic surgery. Data on the following endpoints were evaluated: circumferential margin status, mesorectal grade, number of lymph nodes harvested, rate of conversion to open surgery, postoperative complications, and operative time. Data were summarized as relative risks (RR) or weighted mean differences (WMDs) with 95% confidence intervals (95% CIs). Risk of bias of studies was assessed with standard methods.

Results:
Five trials were eligible, including 334 robotic and 337 laparoscopic surgery cases. Meta-analysis showed that RS was associated with lower conversion rate (7.3%; 4 studies, 544 participants, RR 0.58; 95% CI 0.35–0.97, P = 0.04, I2 = 0%) and longer operating time (MD 38.43 minutes, 95% CI 31.84–45.01: P < 0.00001) compared with laparoscopic surgery. Perioperative mortality, rate of circumferential margin involvement (2 studies, 489 participants, RR 0.82, 95% CI 0.39–1.73), and lymph nodes collected (mean 17.4 Lymph Nodes; 5 trials, 674 patients, MD −0.35, 95% CI −1.83 to 1.12) were similar. The quality of the evidence was moderate for most outcomes.

Conclusion:
Evidence of moderate quality supports that robotic surgery for rectal cancer produces similar perioperative outcomes of oncologic procedure adequacy to conventional laparoscopic surgery. Robotic surgery portraits lower rate of conversion to open surgery, while operating time is significantly longer than by laparoscopic approach.

Published: October 2017

Introduction:
The Zenker diverticulum (ZD) is the most common type of esophageal diverticula. Management of ZD has different options; however, there is a recent increase in treatment with flexible endoscopic myotomy (FEM). In our study, we aimed to investigate the efficacy and safety of FEM among patients with ZD.

Materials and Methods:
The data of patients who underwent FEM for ZD in our clinic between January 2008 and May 2016 were retrospectively analyzed. Myotomy was performed with a needle-knife sphincterotome by using pulse-cut or forced coagulation electrocautery mode. Myotomy was performed on the common wall of the diverticulum up to 0.5 to 1 cm of the distal end. A handmade diverticuloscope, which was modified from an overtube, was used in most of the patients to focus more carefully on the septum. Dysphagia scores of the patients before and after the procedure were compared and complications were evaluated.

Results:
A total of 17 patients were enrolled in the study. The mean age was 65.3 years, and mean diverticular diameter was 3.2 cm. The most common symptoms were dysphagia and regurgitation. The mean in-hospital stay was 5 days. The dysphagia score was significantly decreased after FEM among the patients (0.17±0.39 vs. 2±0.79; P=0.0001). Complications were observed in 3 patients (17.6%); however, there was no procedure-related mortality.

Discussion:
FEM is an efficient and safe procedure as a treatment modality for ZD. However, lack of a standard algorithm is a remarkable disadvantage.

Published: October 2017

Background
As health-related communications become digitized, strategies to increase adoption of these Web-based platforms are needed. The purpose of this study was to assess facilitators and barriers to in-home Internet use among prekidney and postkidney transplant patients.

Methods
A single center, cross-sectional survey of 240 consecutive patients of all levels of technological proficiency who presented to an urban transplant center in the United States. The Patient Information and Technology Assessment consists of 6 demographic questions, 3 disease-related questions, and 8 technology-related questions.

Results
Much of the sample was African American, male with a mean age of 51 years, and median income of $53 800/year. Logistic regression analysis was undertaken, and after adjusting for covariates, we found Smartphone ownership (odds ratio [OR], 4.94; 95% confidence interval [CI], 2.32-10.52), a higher number of Internet users in the home (OR, 2.00; 95% CI, 1.11-3.62), and having college education and beyond (OR, 4.88; 95% CI, 2.03-11.74) increased the likelihood of being a frequent Internet user. African American or Hispanic/Latino patients were less likely to be frequent Internet users compared with white patients (OR, 0.26 and 0.24, respectively, compared with whites, all P < 0.05). As the total number of people in the household increased, frequent Internet use decreased (OR, 0.52; 95% CI, 0.29-0.92). As age increased, reports of frequent Internet use decreased.

Conclusions
Lower rates of Internet use among African Americans and Hispanic/Latinos in urban areas in the United States remains a problem despite a significant increase in access to the Internet and Smartphone ownership. The finding that Internet use increases as the number of Internet users in the household increases indicates that leveraging the patient’s social support network and/or the development of patient information champion programs may aid with patient’s adoption of health technology and patient engagement in self-care.
