Liver biopsy is required when clinically important information about the diagnosis, prognosis or management of a patient cannot be obtained by safer means, or for research purposes. There are several approaches to liver biopsy but predominantly percutaneous or transvenous approaches are used. A wide choice of needles is available and the approach and type of needle used will depend on the clinical state of the patient and local expertise but, for non-lesional biopsies, a 16-gauge needle is recommended. Many patients with liver disease will have abnormal laboratory coagulation tests or receive anticoagulation or antiplatelet medication. A greater understanding of the changes in haemostasis in liver disease allows for a more rational, evidence-based approach to peri-biopsy management. Overall, liver biopsy is safe but there is a small morbidity and a very small mortality so patients must be fully counselled. The specimen must be of sufficient size for histopathological interpretation. Communication with the histopathologist, with access to relevant clinical information and the results of other investigations, is essential for the generation of a clinically useful report.Objective Number of reflux episodes, an adjunctive metric on pH-impedance monitoring, is incompletely studied. We aimed to determine if number of reflux episodes associates with therapeutic outcome in regurgitation predominant gastro-oesophageal reflux disease (GERD). Design We performed post hoc analysis of postintervention pH-impedance data from adult patients with moderate/severe regurgitation despite QD proton pump inhibitor (PPI), randomised to either two times a day PPI or magnetic sphincter augmentation (MSA) in 21 allocation. After 6 and 12 months, symptom response was defined by improvement in Foregut Symptom Questionnaire (FSQ) regurgitation score to none or minimal, ≥50% reduction in GERD health-related quality of life (HRQL) score and satisfaction with therapy. Univariate and multivariate analyses were performed to determine predictors of symptom improvement. Results Of 152 randomised patients, 123 (age 46.9±1.2 year, 43% female) had complete data. Symptom and satisfaction scores significantly improved after MSA compared with two times a day PPI. https://www.selleckchem.com/products/Adriamycin.html Both acid exposure time (13.4%±0.7% to 1.3±0.2%, p80 episodes pretreatment predicted improvement. Conclusions Reduction of reflux episodes on pH-impedance to physiological levels associates with improved outcomes, while pathological levels predict improvement with MSA in regurgitation predominant GERD.

Without collision screening, the planner may compromise optimal planning, unnecessary re-planning delays can occur, and incomplete treatments may be delivered. To address these concerns, we developed a software for collision prediction based on simple machine measurements. Materials and methods Three types of collision were identified; gantry-couch mount, gantry-couch and gantry-patient. Trigonometric formulas to calculate the distance from each potential point of collision to the gantry rotation axis were generated. For each point, collision occurs when that distance is greater than the gantry head to gantry rotational axis distance. The colliding arc for each point is calculated. A computer code incorporating these formulas was generated. The inputs required are the couch coordinates relative to the isocenter, the patient dimensions, and the presence or absence of a circular SRS collimator. The software outputs the collision-free gantry angles, and for each point, the shortest distance to the gantry or the colliding sector when collision is identified. The software was tested for accuracy on a TrueBEAM® machine equipped with BrainLab® accessories for 80 virtual isocenter-couch angle configurations with and without a circular collimator and a parallelepiped phantom. Results The software predicted the absence of collision for 19 configurations. The mean absolute error between the measured and predicted gantry angle of collision for the remaining 61 cases was 0.86 (0.01-2.49). Conclusion This tool accurately predicted collisions for linac-based intracranial SRS and is easy to implement in any radiotherapy facility.Background Completion lymph node dissection (CLND) for malignant melanoma is performed for regional cancer control and is associated with a high complication rate. It is unknown whether post-operative complications influence cancer recurrence or survival. Our aim was to evaluate the risk factors for short- and long-term complications after CLND, and to determine whether complications affect recurrence or survival. Method We performed a retrospective cohort study including all melanoma patients who underwent CLND in the Stockholm region during 2005-2014. Patient and cancer characteristics were collected from medical records, as were clinical outcomes. Assessment was performed by multivariate logistic regression. Results Among 144 patients, the risk of any post-operative one year complication was 68.8%. Lymphedema (41.0%), infection (37.5 %), and seroma (31.3 %) were the most common complications. Diabetes and inguinal CLND were associated with nine- and ten-fold increased risks of post-operative complications (p less then 0.05), respectively. Complications were linked to an increased risk of recurrent cancer (p less then 0.05), median follow-up time of 49 months, but did not appear to affect five-year survival. Conclusion Post-operative complications are common in melanoma patients undergoing CLND. Strong risk factors for complications are diabetes and inguinal CLND. Post-operative complications appear to be associated with increased risks of recurrent cancer, but the mechanism is unknown.Revascularisation of the brachial plexus is controversial. Traditional techniques use free tissue transfer of omentum, groin fat or muscle, on the principle of supplying rich quantities of vascularised tissue to wrap around the nerves permitting neural gliding and revascularising the scarred nerves. However, the complexity of an additional microsurgical procedure coupled with uncertainty of their effectiveness have curtailed their clinical application. We describe a local pedicled transposition flap that is a novel modification of the deltopectoral (DP) flap using only the subcutaneous adipofascial tissue vascularised by the medial pectoral perforators. This flap is harvested through the supraclavicular brachial plexus access incision. This avoids free tissue transfer and additional donor scarring, yet provides adequate volumes of well-vascularised tissue for mechanical protection and revascularisation of the plexus. We reviewed sixteen consecutive patients who underwent a pedicled adipofascial DP flap to protect the brachial plexus over the 20-year study period. Inclusion criteria were patients with recurrent thoracic outlet compression and patients with radiation plexitis. At latest follow-up (average 3.6 years), 75% of patients reported the improvement or resolution of symptoms. The majority of patients reported improved pain scores (82%) with an average pain visual analogue scale (VAS) score of 5.1. Patients were very satisfied with scar outcomes, reporting low Vancouver Scar Scale Scores and low scar VAS scores. Post-operative MR imaging, available in 31% of the cohort, demonstrates the maintenance of flap position and vascularity at an average of 2.1 years. This novel and simple technique is recommended in aiding revascularisation and cover of the brachial plexus in recurrent and recalcitrant plexopathy.Introduction Radiation therapy (RT) is a complex process that employs high-dose radiation for therapeutic purposes. Incident reporting and analysis, in addition to being a legal requirement in RT, provides information that helps to improve patient safety. This paper describes our experiences over a 9 year period in which a local incident reporting and learning system (SNAI) specific to RT was employed. Materials and methods The center has 4 lineal accelerators that treat a total of 1900 patients annually. The first action taken with a view to improving patient safety was the implementation of a multidisciplinary RT safety group (GSRT), who decided to employing a methodology based on incident reporting. For this purpose, a local SNAI was implemented, adapting the ROSEIS incident reporting system used and consolidated by the European Society of Radiation Oncology Therapy (ESTRO). All incidents in which patients received an incorrect RT session were considered adverse events (AE) and were thus analyzed. Finally, the professionals considered that the methodology used in the analysis of incidents was not totally objective i.e punitive in nature. Conclusions The safety of the patient receiving RT has been approached from a methodology based on a local SNAI. The analysis of reported incidents has promoted various actions aimed at improving the safety of patients receiving RT. The methodology used has been well received by the workers and has helped to introduce a culture of patient safety for the majority of professionals involved. Furthermore, the local SNAI facilitates compliance with European regulations regarding the obligation to record incidents in RT.Objective To determine whether cardiac arrests occurring at night or during the weekend, carry lower immediate survival. Method An analysis of logistic regression was performed, adjusted for age, sex, time to care of the cardiac arrest and first monitored rhythm, to determine whether there are differences in immediate survival. Results The immediate survival of the cohort studied (n=121) was 32 patients (26%). A difference of 13% in immediate survival between both periods studied was found. link2 The logistic regression analysis taking immediate survival as an effect, showed that suffering an in-hospital cardiac arrest during evenings or weekends was a variable that is not associated with a successful outcome. link3 The OR .48 (95% CI .20-1.12; P=.08). Conclusions Patients who suffer a cardiac arrest in our centre during evenings or weekends are more vulnerable.People with disabilities make up the largest minority population in the country, yet our health care workforce is unprepared to meet their needs. Two initiatives - and the Alliance for Disability in Health Care Education's Disability Competencies and the Resources for Integrated Care Disability-Competent Care model-provide essential tools to build a health care workforce prepared to meet the health needs of people with disabilities. We note gaps in health education and continuing education curricula, document barriers to progress, and demonstrate how the two initiatives offer a clear roadmap to effect systemic change. Finally, we issue a call to action for health care education, practice, and research to ensure a health care workforce prepared to provide quality health care to people with disabilities.Objectives Falls and neuropsychiatric symptoms (NPS) are common among long-term care residents with cognitive impairment. Despite the high prevalence of falls and NPS, little is known about their association. The aim of our study was to explore how NPS, particularly the severity of NPS and specific NPS subgroups, are associated with falls and how psychotropics modify this association. Design Longitudinal cohort study. Setting and participants In total, 532 long-term care residents aged 65 years or older in Helsinki, Finland. Methods NPS were measured with Neuropsychiatric Inventory (NPI) at baseline. Participants were grouped into 3 groups no significant NPS (NPI points 0‒3), low NPS burden (NPI 4‒12), and high NPS burden (NPI >12). The number of falls, injuries, fractures, and hospitalizations were collected from medical records over 12 months following baseline assessment. Results Altogether, 606 falls occurred during the follow-up year. The falls led to 121 injuries, 42 hospitalizations, and 20 fractures. Falls and injuries increased significantly with NPS burden (P less then .
