Published: January 2014

ObjectivesTo investigate how bowel dysfunction after sphincter-preserving rectal cancer treatment, known as low anterior resection syndrome (LARS), is perceived by rectal cancer specialists, in relation to the patient's experience.DesignQuestionnaire study.SettingInternational.Participants58 rectal cancer specialists (45 colorectal surgeons and 13 radiation oncologists).Research procedureThe Low Anterior Resection Syndrome Score (LARS score) is a five-item instrument for evaluation of LARS, which was developed from and validated on 961 patients. The 58 specialists individually completed two LARS score-based exercises. In Exercise 1, they were asked to select, from a list of bowel dysfunction issues, five items that they considered to disturb patients the most. In Exercise 2, they were given a list of scores to assign to the LARS score items, according to the impact on quality of life (QOL).Outcome measuresIn Exercise 1, the frequency of selection of each issue, particularly the five items included in the LARS score, was compared with the frequency of being selected at random. In Exercise 2, the answers were compared with the original patient-derived scores.ResultsFour of the five LARS score issues had the highest frequencies of selection (urgency, clustering, incontinence for liquid stool and frequency of bowel movements), which were also higher than random. However, the remaining LARS score issue (incontinence for flatus) showed a lower frequency than random. Scores assigned by the specialists were significantly different from the patient-derived scores (p<0.01). The specialists grossly overestimated the impact of incontinence for liquid stool and frequent bowel movements on QOL, while they markedly underestimated the impact of clustering and urgency. The results did not differ between surgeons and oncologists.ConclusionsRectal cancer specialists do not have a thorough understanding of which bowel dysfunction symptoms truly matter to the patient, nor how these symptoms affect QOL.

ObjectivesWe aimed to examine staff members’ perceptions of communication within and between different professions, safety attitudes and psychological empowerment, prior to and after implementation of the communication tool Situation-Background-Assessment-Recommendation (SBAR) at an anaesthetic clinic. The aim was also to study whether there was any change in the proportion of incident reports caused by communication errors.DesignA prospective intervention study with comparison group using preassessments and postassessments. Questionnaire data were collected from staff in an intervention (n=100) and a comparison group (n=69) at the anaesthetic clinic in two hospitals prior to (2011) and after (2012) implementation of SBAR. The proportion of incident reports due to communication errors was calculated during a 1-year period prior to and after implementation.SettingAnaesthetic clinics at two hospitals in Sweden.ParticipantsAll licensed practical nurses, registered nurses and physicians working in the operating theatres, intensive care units and postanaesthesia care units at anaesthetic clinics in two hospitals were invited to participate.InterventionImplementation of SBAR in an anaesthetic clinic.Primary and secondary outcomesThe primary outcomes were staff members’ perception of communication within and between different professions, as well as their perceptions of safety attitudes. Secondary outcomes were psychological empowerment and incident reports due to error of communication.ResultsIn the intervention group, there were statistically significant improvements in the factors ‘Between-group communication accuracy’ (p=0.039) and ‘Safety climate’ (p=0.011). The proportion of incident reports due to communication errors decreased significantly (p<0.0001) in the intervention group, from 31% to 11%.ConclusionsImplementing the communication tool SBAR in anaesthetic clinics was associated with improvement in staff members’ perception of communication between professionals and their perception of the safety climate as well as with a decreased proportion of incident reports related to communication errors.Trial registrationISRCTN37251313.

ObjectivesTo test the effects of a school-based prevention programme on students’ smoking-related behaviour, attitudes and knowledge 6 months after implementation over 2 school-years has ended.DesignTwo-arm prospective cluster randomised controlled trial with a follow-up survey 6 months after end of programme implementation, that is, 26 months after baseline.Setting45 public secondary schools from four federal states in Germany (Bremen, Hesse, North Rhine-Westphalia, Schleswig-Holstein).ParticipantsA total of 3444 students from 172 classes with a mean age of 10.37 years (SD=0.59) and 47.9% girls at baseline. Analysis sample with follow-up up data merged to baseline data comprises 2513 datasets (73%).Intervention‘Eigenständig werden 5+6’, a school-based prevention programme for grades 5 and 6 to enhance substance-specific and general life skills, consisting of 14 units (à 90 min) and two workshops (4–6 h) being taught over a time period of 2 school-years by trained teachers.Outcome measuresLifetime and current smoking, incidence of smoking in baseline never smokers, smoking-related knowledge, attitudes, perceived norms of smoking and self-efficacy to refuse cigarette offers were assessed in students.Results6 months after the end of programme implementation, students of intervention classes showed significantly lower rates for lifetime smoking (adjusted OR=0.63; 95% CI 0.41 to 0.96; p=0.026) and incidence of smoking (adjusted OR=0.66; 95% CI 0.43 to 1.00; p=0.047), a higher increase of smoking-related knowledge (adjusted β=9.38; 95% CI 6.73 to 12.04; p<0.001) and a greater change in attitudes towards a more critical perception of risks and disadvantages of smoking (adjusted β=0.10; 95% CI 0.03 to 0.16; p=0.002). No group differences were found for current smoking, perceived norms of smoking and self-efficacy to refuse cigarette offers.ConclusionsParticipation in the school-based prevention programme ‘Eigenständig werden 5+6’ may have small effects on smoking behaviour and attitudes and a moderate effect on smoking-related knowledge.Trial registrationCurrent Controlled Trials ISRCTN99442407
Identity cards help patients identify their doctors
Authors: Zucco Liana , Desmond Gabrielle , Carpenter Bernadette 
Published: January 2014

AbstractPatients admitted to hospital are immediately overloaded with information from staff in A&E, to subsequent acute medical and inpatient wards. Essential details are conveyed to patients at each step, including diagnosis, management and identification of various team members involved in their care. An initial audit within our South London hospital revealed only one third of patients admitted onto a single medical ward could recall the name of a single member of their treating team, and less than 10% retained that information over 5 days. Identification (ID) cards were devised to facilitate clear transfer of information detailing the patient’s treating team. These ID cards were piloted through a series of PDSA cycles on one inpatient medical ward following a consultant led ward round. Post intervention, 67% managed to recall a single member of the treating team, with 67% retaining this information 5 days later, a dramatic improvement. ID cards were then trialed on one surgical ward, demonstrating equally impressive results with over 87% of patients recalling their named consultant following ID card implementation, up from 54% initially. Similar trends were demonstrated for recalling other treating team members. This simple measure improved patients ability to recall and retain names of a least a single member of their treating team, encouraged communication between patients and medical team and ultimately improved patient satisfaction and quality of care. ID cards were quick and easy to implement and have been approved by the hospital patient safety committee to implement throughout the Trust.
Prevalence of functional gastrointestinal disorders among consecutive new patient referrals to a gastroenterology clinic
Authors: Shivaji Uday N , Ford Alexander C 
Published: January 2014

ObjectiveFunctional gastrointestinal disorders (FGIDs) are common in the community. Many patients will consult a physician in primary care, but the burden that these diseases represent to secondary care has not been studied for many years. We therefore examined this subject.DesignUnselected consecutive new adult patient referrals were recruited during a 3-year period from January 2010 until December 2012. Medical records were reviewed retrospectively and the following data were recorded: age and sex of the patient, symptoms reported or signs noted at the first consultation, all investigations requested and ultimate diagnosis after investigation to the level deemed appropriate by the consulting physician.SettingA luminal gastroenterology clinic at a teaching hospital.ResultsThere were a total of 613 new patient referrals (mean age 54.2 years, 357 (58.2%) female). In total, 214 (34.9%) patients were diagnosed as having an FGID. Among the 214 patients diagnosed with an FGID, 65.9% were female, compared with 54.1% without an FGID (p=0.005). Mean age of those with an FGID was 47.9 years, compared with 57.5 years among those without (p<0.001). The total number of symptoms reported was significantly higher among patients with an FGID, but the total number of investigations did not differ.ConclusionsMore than one-third of new patient referrals to a luminal gastroenterology clinic were diagnosed with an FGID. These conditions form a large part of the workload in secondary care gastroenterology, and primary care commissioning needs to reflect this.

Published: January 2014

ObjectivesThe purpose of this study was to investigate the characteristics associated with fatal and non-fatal low-speed vehicle run-over (LSVRO) events in relation to person, incident and injury characteristics, in order to identify appropriate points for intervention and injury prevention.MethodsData on all known LSVRO events in Queensland, Australia, over 11 calendar years (1999–2009) were extracted from five different databases representing the continuum of care (prehospital to fatality) and manually linked. Descriptive and multivariate analyses were used to analyse the sample characteristics in relation to demographics, health service usage, outcomes, incident characteristics, and injury characteristics.ResultsOf the 1641 LSVRO incidents, 98.4% (n=1615) were non-fatal, and 1.6% were fatal (n=26). Over half the children required admission to hospital (56%, n=921); mean length of stay was 3.4 days. Younger children aged 0–4 years were more frequently injured, and experienced more serious injuries with worse outcomes. Patterns of injury (injury type and severity), injury characteristics (eg, time of injury, vehicle type, driver of vehicle, incident location), and demographic characteristics (such as socioeconomic status, indigenous status, remoteness), varied according to age group. Almost half (45.6%; n=737) the events occurred outside major cities, and approximately 10% of events involved indigenous children. Parents were most commonly the vehicle drivers in fatal incidents. While larger vehicles such as four-wheel drives (4WD) were most frequently involved in LSVRO events resulting in fatalities, cars were most frequently involved in non-fatal events.ConclusionsThis is the first study, to the authors’ knowledge, to analyse the characteristics of fatal and non-fatal LSVRO events in children aged 0–15 years on a state-wide basis. Characteristics of LSVRO events varied with age, thus age-specific interventions are required. Children living outside major cities, and indigenous children, were over-represented in these data. Further research is required to identify the burden of injury in these groups.

PurposeTo evaluate the feasibility, safety and efficacy of endovascular treatment with flow diverters in patients with recanalized and multitreated aneurysms in a retrospective, multicenter, single-arm study.MethodsThe study included 29 patients with 29 recanalized aneurysms who were treated by flow diverters (Silk or Pipeline devices). Pre- and post-procedural complications and morbidity and mortality rates were evaluated and functional outcomes (modified Rankin Score (mRS)) at 1 month (short-term) and 3–4 months (mid-term) were compared with preoperative mRS (before the procedure). Mid-term angiographic follow-up was performed assessing aneurysmal occlusion by the Montreal scale (complete occlusion, neck remnant, aneurysm remnant).ResultsPlacement of the flow diverters was achieved in all patients. Two misdeployments of the flow diverters necessitated balloon dilation in two patients, which was associated with stent delivery in one patient. Permanent morbidity related to treatment was 6.9% (2/29), transient morbidity was 10.3% (3/29) and there were no deaths resulting from the treatment. One patient died from a myocardial infarct 4 weeks after the procedure. 25/29 patients (86.2%) had a good final functional outcome, 26/29 (89.7%) had an unchanged functional outcome and 2/29 patients (6.9%) had clinical worsening. Angiographic follow-up showed complete occlusion in 17/28 patients (60.7%), neck remnants in 6/28 patients (21.4%) and residual aneurysms in 5/28 (17.9%).ConclusionsFlow diverter placement is feasible and safe in patients with recanalized and multitreated aneurysms. The procedure is associated with a high percentage of good functional outcomes as well as good mid-term anatomical results (82.1%).

Published: January 2014

The advent of advanced single molecule measurements heralded the arrival of a wealth of dynamic information revolutionizing our understanding of protein dynamics and behavior in ways not deducible by conventional bulk assays. They offered the direct observation and quantification of the abundance and life time of multiple states and transient intermediates in the energy landscape that are typically averaged out in non-synchronized ensemble measurements, thus providing unprecedented insights into complex biological processes. Here we survey the current state of the art in single-molecule fluorescence microscopy methodology for studying the mechanism of enzymatic activity and the insights on protein functional dynamics. We will initially discuss the strategies employed to date, their limitations and possible ways to overcome them, and finally how single enzyme kinetics can advance our understanding on mechanisms underlying function and regulation of proteins. [Formula: see text]Special Issue Comment: This review focuses on functional dynamics of individual enzymes and is related to the review on ion channels by Lu,44 the reviews on mathematical treatment of Flomenbom45 and Sach et al.,46 and review on FRET by Ruedas-Rama et al.41

AbstractThe ability of human γδ T cells from healthy donors to kill pancreatic ductal adenocarcinoma (PDAC) in vitro and in vivo in immunocompromised mice requires the addition of γδ T-cell–stimulating antigens. In this study, we demonstrate that γδ T cells isolated from patients with PDAC tumor infiltrates lyse pancreatic tumor cells after selective stimulation with phosphorylated antigens. We determined the absolute numbers of γδ T-cell subsets in patient whole blood and applied a real-time cell analyzer to measure their cytotoxic effector function over prolonged time periods. Because phosphorylated antigens did not optimally enhance γδ T-cell cytotoxicity, we designed bispecific antibodies that bind CD3 or Vγ9 on γδ T cells and Her2/neu (ERBB2) expressed by pancreatic tumor cells. Both antibodies enhanced γδ T-cell cytotoxicity with the Her2/Vγ9 antibody also selectively enhancing release of granzyme B and perforin. Supporting these observations, adoptive transfer of γδ T cells with the Her2/Vγ9 antibody reduced growth of pancreatic tumors grafted into SCID-Beige immunocompromised mice. Taken together, our results show how bispecific antibodies that selectively recruit γδ T cells to tumor antigens expressed by cancer cells illustrate the tractable use of endogenous γδ T cells for immunotherapy.

Abstract
To date, no specific marker exists for the detection of circulating tumor cells (CTC) from different types of sarcomas, though tools are available for detection of CTCs in peripheral blood of patients with cancer for epithelial cancers. Here, we report cell-surface vimentin (CSV) as an exclusive marker on sarcoma CTC regardless of the tissue origin of the sarcoma as detected by a novel monoclonal antibody. Utilizing CSV as a probe, we isolated and enumerated sarcoma CTCs with high sensitivity and specificity from the blood of patients bearing different types of sarcoma, validating their phenotype by single cell genomic amplification, mutation detection, and FISH. Our results establish the first universal and specific CTC marker described for enumerating CTCs from different types of sarcoma, thereby providing a key prognosis tool to monitor cancer metastasis and relapse.

Abstract
Perineural tumor invasion of intrapancreatic nerves, neurogenic inflammation, and tumor metastases along extrapancreatic nerves are key features of pancreatic malignancies. Animal studies show that chronic pancreatic inflammation produces hypertrophy and hypersensitivity of pancreatic afferents and that sensory fibers may themselves drive inflammation via neurogenic mechanisms. Although genetic mutations are required for cancer development, inflammation has been shown to be a precipitating event that can accelerate the transition of precancerous lesions to cancer. These observations led us to hypothesize that inflammation that accompanies early phases of pancreatic ductal adenocarcinoma (PDAC) would produce pathologic changes in pancreatic neurons and innervation. Using a lineage-labeled genetically engineered mouse model of PDAC, we found that pancreatic neurotrophic factor mRNA expression and sensory innervation increased dramatically when only pancreatic intraepithelial neoplasia were apparent. These changes correlated with pain-related decreases in exploratory behavior and increased expression of nociceptive genes in sensory ganglia. At later stages, cells of pancreatic origin could be found in the celiac and sensory ganglia along with metastases to the spinal cord. These results demonstrate that the nervous system participates in all stages of PDAC, including those that precede the appearance of cancer. Cancer Res; 74(6); 1718–27. ©2014 AACR.

Abstract
Protein phosphatase 2A (PP2A) is a tumor suppressor that regulates many signaling pathways crucial for cell transformation. In fact, decreased activity of PP2A has been reported as a recurrent alteration in many types of cancer. Here, we show that PP2A is frequently inactivated in patients with colorectal cancer, indicating that PP2A represents a potential therapeutic target for this disease. We identified overexpression of the endogenous PP2A inhibitors SET and CIP2A, and downregulation of regulatory PP2A such as PPP2R2A and PPP2R5E, as contributing mechanisms to PP2A inhibition in colorectal cancer. Moreover, we observed that its restoration using FTY720 impairs proliferation and clonogenic potential of colorectal cancer cells, induces caspase-dependent apoptosis, and affects AKT and extracellular signal-regulated kinase-1/2 activation status. Interestingly, treatment with FTY720 showed an additive effect with 5-fluorouracil, SN-38, and oxaliplatin, drugs used in standard chemotherapy in patients with colorectal cancer. These results suggest that PP2A activity is commonly decreased in colorectal cancer cells, and that the use of PP2A activators, such as FTY720, might represent a potential novel therapeutic strategy in colorectal cancer.
