Local anaesthesia efficacy as postoperative analgesia for open shoulder instability surgery. a prospective randomised controlled study

Background and objectives: The aim of present study was to evaluate for the first time, the clinical effect of local anaesthetic infiltration as postoperative analgesia in open shoulder surgery for anterior-inferior instability. The comparison of the local infiltration and interscalenic brachial plexus block to a control group test the local anaesthetic efficacy in this surgery. Methods: 78 patients scheduled for open shoulder surgery were enrolled and randomly assigned to one of three groups: local infiltration anaesthesia (LIA), interscalenic brachial plexus block (IBPB) and control (C). All patients received standardized general anaesthesia and all injections were performed with the same dose and volume of anaesthetic. The number boluses delivered by a PCA pump applied at the end of surgery and the visual analogue score (VAS) at 0, 2, 4, 6, 12, 18 and 24 hours after intervention were recorded. A patient satisfaction score was also assessed. Results: Mean bolus consumption of the rescue analgesic, compared to C, was significantly less both in the LIA and IBPB groups (P<0.05). The IBPB group showed VAS scores that were significantly better than C group at all time points (P<0.05). The VAS scores for LIA group were clinically comparable to IBPB, and only at the 2 and 6 hours, postoperative time points there were no significant differences found in respect to the C group. IBPB and LIA showed comparable patient satisfaction scores. Conclusion: The local anaesthetic infiltration as postoperative analgesia appears to be a clinically valid alternative, statistically comparable to IBPB, with no clinical meaningful adverse effects

Negative pressure wound therapy versus healing by secondary intention in pressure ulcers

Pressure ulcers are a highly prevalent source of morbidity with an equally high incidence of up to 38.0\% amongst different categories of healthcare institutions. Therefore, the management and therapeutic approach toward these often hospital- or facility-acquired problems remain critical aspects of long-term care. Negative pressure wound therapy (NPWT) has proven effective in addressing the barriers to pressure ulcer healing including increasing blood flow to previously ischemic wound areas by generating subatmospheric pressure which vacuums in circulation. The objective of this study was to compare negative pressure wound therapy (NPWT) versus surgical wounds healing by secondary intention (SWHSI). A systematic literature search was conducted using the PubMed and Scopus search engine up until the 20 Th January 2017 including the terms: "negative pressure wound therapy" and "pressure ulcers". In this systematic review, six randomized controlled trials were included. NPWT is deemed appropriate and effective method and widely used by clinicians to promote the healing of wounds and ulcers of different etiology. The heterogeneity found in individual trials regarding the inclusion criteria, therapeutic procedures, the criteria and methods of outcome evaluation, however, did not allow for a data evaluation with statistically valid conclusions. It is reasonable to assume that their subset of patients with pressure ulcers that can be effectively treated with NPWT, with optimal results and good cost-benefit ratio, also with respect to the quality of life

Research progress on aerobiology in the last 30 years. A focus on methodology and occupational health

Aerobiology, as a scientific discipline, developed during the last century and has been applied to different types of organisms and scenarios. In the context of the Integrated Evaluation of Indoor Particulate Exposure (VIEPI) project, we conducted a bibliometric study of the scientific literature on aerobiology from the last three decades, establishing the recent advances and the critical issues regarding the application of aerobiological methods to occupational settings. The data were collected from Scopus,Web of Science and PubMed. We explored the distribution of the articles in different years and research areas and realized a bibliometric analysis using the CiteSpace software. The results indicated that the number of publications is increasing. The studies related to environmental sciences were the most represented, while the number of occupational studies was more limited. The most common keywords were related to pollen, fungal spores and their relation with phenology, climate change and human health. This article shows that aerobiology is not restricted to the study of pollen and spores, extending the discipline and the application of aerobiological methods to occupational settings, currently under-explored

Supervised Anomaly Detection in Crude Oil Stabilization

In recent years, pervasive digitalization has affected the industrial world, including the oil and gas sector. With more and more data becoming available, Machine Learning algorithms have become a promising tool to improve Predictive Maintenance operations. In this work, we have designed an alerting system that notifies the site operator with an adequate advance when an anomaly is going to occur. In particular, we focus our analysis on the stabilization column of an Oil Stabilization Facility to prevent the column bottom temperature to overcome safety boundaries. The experimental analysis demonstrates that our system provides reliable results, in terms of both identified anomalies and false alarms. In addition, the system is currently under deployment on the company computing infrastructure and the first working version will be available by the end of May 202

Radiotherapy at oligoprogression for metastatic castration-resistant prostate cancer patients: a multi-institutional analysis

Purpose To retrospectively estimate the impact of radiotherapy as a progression-directed therapy (PDT) in oligoprogressive metastatic castration-resistant prostate cancer (mCRPC) patients under androgen receptor-target therapy (ARTT). Materials and methods mCRPC patients are treated with PDT. End-points were time to next-line systemic treatment (NEST), radiological progression-free survival (r-PFS) and overall survival (OS). Toxicity was registered according to Common Terminology Criteria for Adverse Events v4.0. Survival analysis was performed using the Kaplan-Meier method; univariate and multivariate analyses were performed. Results Fifty-seven patients were analyzed. The median follow-up after PDT was 25.2 months (interquartile, 17.1-44.5). One-year NEST-free survival, r-PFS and OS were 49.8%, 50.4% and 82.1%, respectively. At multivariate analysis, polymetastatic condition at diagnosis of metastatic hormone-sensitive prostate cancer (mHSPC) (HR 2.82, p = 0.004) and PSA doubling time at diagnosis of mCRPC (HR 2.76, p = 0.006) were associated with NEST-free survival. The same variables were associated with r-PFS (HR 2.32, p = 0.021; HR 2.24, p = 0.021). One patient developed late grade >= 2 toxicity. Conclusion Our study shows that radiotherapy in oligoprogressive mCRPC is safe, is effective and seems to prolong the efficacy of ARTT in patients who otherwise would have gone systemic treatment switch, positively affecting disease progression. Prospective trials are needed

Adrenal Modulation & Perceived Distress of BC Survivors

Background: Distress and adrenal balance of breast cancer survivors (BCS) are key elements of their psychophysical health, and increasing evidence has shown both physical exercise and the natural environment are effective for their modulation. The aim of the study was to evaluate the acute effects of the environment and type of light intensity workouts, on distress, salivary cortisol and dehydroepiandrosterone sulfate (DHEA-S) in BCS.Methods: Twenty-four BCS participated in six different workouts, each with the same duration and intensity. Three of them were conducted in natural environments – walking (Wnature), canoeing with assistance (Cnature) and a mix of myofascial and yoga exercises (MYnature). The others were conducted in an urban environment, namely walking (Wurban), or an indoor environment, namely mobilisation and light upper body exercises (MCgym) and a mix of myofascial and yoga exercises (MYgym). Before and after each workout, the Distress Thermometer was completed and saliva was collected.Results: Workouts practised in natural environments elicited a higher reduction in cortisol and the cortisol to DHEA-S ratio and a greater DHEA-S increase compared with workouts practised in urban and indoor environments. Overall, Cnature and MYnature were the best activities; among those practised in urban and indoor environments, MYgym elicited the best results. Distress was not acutely reduced after Wurban and MCgym. Conclusion: Natural environments seem to provide the best management of distress, cortisol, DHEA-S and their balance when working out at light intensities. The simultaneous presence of forests and rivers seems to be the key element of the observed results

Report from the 4th European Bone Sarcoma Networking meeting: focus on osteosarcoma

Abstract This report summarizes the proceedings of the 4th European Bone Sarcoma Networking Meeting, held in London, England, on 21 June 2017. The meeting brought together scientific and clinical researchers and representatives from sarcoma charities from 19 countries representing five networks across Europe, to present and discuss new developments on bone sarcoma. In view of the challenges is poses, the meeting focussed primarily on osteosarcoma with presentations on developments in our understanding of osteosarcoma genetics and immunology as well as results from preclinical investigations and discussion of recent and ongoing clinical trials. These include studies examining the efficacy of multi-targeted tyrosine kinase inhibitors and checkpoint inhibitors, as well as those with molecular profiling to stratify patients for specific therapies. Discussion was centred on generation of new hypotheses for collaborative biological and clinical investigations, the ultimate goal being to improve therapy and outcome in patients with bone sarcomas

Recommendations for radiation therapy in oligometastatic prostate cancer:An ESTRO-ACROP Delphi consensus

Background and purpose: Oligometastatic prostate cancer is a new and emerging treatment field with only few prospective randomized studies published so far. Despite the lack of strong level I evidence, metastasis-directed therapies (MDT) are widely used in clinical practice, mainly based on retrospective and small phase 2 studies and with a large difference across centers. Pending results of ongoing prospec-tive randomized trials, there is a clear need for more consistent treatment indications and radiotherapy practices.Material and methods: A European Society for Radiotherapy and Oncology (ESTRO) Guidelines Committee consisting of radiation oncologists' experts in prostate cancer was asked to answer a dedicated question-naire, including 41 questions on the main controversial issues with regard to oligometastatic prostate cancer.Results: The panel achieved consensus on patient selection and routine use of prostate-specific mem-brane antigen positron emission tomography (PSMA PET) imaging as preferred staging and restaging imaging. MDT strategies are recommended in the de novo oligometastatic, oligorecurrent and oligopro-gressive disease setting for nodal, bone and visceral metastases. Radiation therapy doses, volumes and techniques were discussed and commented.Conclusion: These recommendations have the purpose of providing standardization and consensus to optimize the radiotherapy treatment of oligometastatic prostate cancer until mature results of random-ized trials are available.AT would like to acknowledge the support of Cancer Research UK (C33589/A28284 and C7224/A28724) .
