MEDIATION: An eMbEddeD System for Auditory Feedback of Hand-water InterAcTION while Swimming

Cesarini D, Calvaresi D, Farnesi C, et al. MEDIATION: An eMbEddeD System for Auditory Feedback of Hand-water InterAcTION while Swimming. Procedia Engineering. 2016;147:324-329.In swimming sport, the proper perception of moving water masses is a key factor. This paper presents an embedded system for the acquisition of values of pressure on swimmers hands and their transformation into sound. The sound, obtained using sonification, is used as an auditive representation of hand-water interactions while swimming in water. The sound obtained is used as an auditive feedback for the swimmer and as an augmented communication channel between the swimming trainer and the athlete. The developed system is self-contained, battery powered and able to work continuously for over eight hours, thus, representing a viable solution for daily usage in swimmers training. Preliminary results from in-pool experiments with both novel and experienced swimmers demonstrate the high acceptability of this technology and its promising future evolution and usage possibilities

Metabolic-imaging of human glioblastoma live tumors: A new precision-medicine approach to predict tumor treatment response early

Glioblastoma (GB) is the most severe form of brain cancer, with a 12-15 month median survival. Surgical resection, temozolomide (TMZ) treatment, and radiotherapy remain the primary therapeutic options for GB, and no new therapies have been introduced in recent years. This therapeutic standstill is primarily due to preclinical approaches that do not fully respect the complexity of GB cell biology and fail to test efficiently anti-cancer treatments. Therefore, better treatment screening approaches are needed. In this study, we have developed a novel functional precision medicine approach to test the response to anticancer treatments in organoids derived from the resected tumors of glioblastoma patients

Elective cancer surgery in COVID-19-free surgical pathways during the SARS-CoV-2 pandemic: An international, multicenter, comparative cohort study

PURPOSE As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19–free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19–free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19–free surgical pathways. Patients who underwent surgery within COVID-19–free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19–free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score–matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19–free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION Within available resources, dedicated COVID-19–free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks

Experimental Design and Development of an Embedded Computer Vision System for Detection and Analysis of Pantographs

Design and development of a vision system for detection and analysis of the pantograph head. The proposed architecture detects, tracks, and analyzes the position of the pantograph head and its geometrical structure to identify possible sources of defects that could be risky for train circulation. The system records images, localizes relevant frames, compensates images color. Then, for the relevant images, the system detects the position and the spatial orientation of the pantograph head. Particular care has been posed to achieve precise shape and localization of the head. I developed a new processing pipeline that sequentially improves position accuracy. The pipeline exploits Computer Vision techniques such as template matching; machine learning (through HAAR cascade recognition and HOG objects detection; key features detection (SIFT and ORB algorithms); foreground extraction (GrabCut); color filtering with edge preservation; lines detection (Hough Transform). Several parameters have optimized through relevant comparative analyses that address the accuracy of the final result and robustness of detection. Experimental results have been compared with a ground-truth composed of field data acquisition and result labeled by humans. The achieved results demonstrated the capability of the system for being used as a decision support system in maintenance activities

Prevalence, characteristics, and treatment of fatigue in oncological cancer patients in Italy. a cross-sectional study of the Italian Network for Supportive Care in Cancer (NICSO)

Background: Fatigue is one of the most distressing symptoms of cancer patients. Its characteristics and impact on quality of life have not been fully explored and treatment of cancer-related fatigue in Italian oncological centers has not been codified. Methods: A cross-sectional study was carried out on all patients attending for any reason the 24 participating centers in two non-consecutive days. Patients with fatigue filled out the Brief Fatigue Inventory (BFI) questionnaire and reported any pharmacological or non-pharmacological treatment for fatigue. Results: From October 2014 to May 2015, 1394 cancer patients agreed to participate in the study. Fatigue was referred by 866 (62.1%) of patients; its duration was > 4 months in 441 patients (50.9%). In the investigators’ opinion, the most important (probable or almost sure) determinants of fatigue were reduced physical activity (271 patients), anxiety (149), pain (131), insomnia (125), anemia (123), and depression (123). Fatigue of moderate/severe intensity was reported by 43%/29.2% of patients, while usual fatigue in the last 24 h by 45%/33.1%, and the worst fatigue in the last 24 h by 33%/54.8%, respectively. Concerning the impact on quality of life, fatigue interfered moderately/severely with general activity in 30.8%/38.6% of patients, with mood in 26.1%/32.8%, with the ability to work in 27.9%/35.6%, with normal work in 26.7%/38.9%, with relationships with others in 21%/23.4% and with the ability to amuse themselves in 22.2%/33.1%. Only 117/866 patients (13.5%) received a pharmacological treatment represented by a corticosteroid in 101 patients (86.3%) while 188 patients (21.7%) received a non-pharmacological treatment such as physical exercise (120 patients, 63.8%) and various alimentary supplements (52 patients, 27.6%). Conclusions: Cancer-related fatigue is frequently reported by oncological patients; its intensity and impact on quality of life is relevant

Breakthrough Cancer Pain: Preliminary Data of The Italian Oncologic Pain Multisetting Multicentric Survey (IOPS-MS)

Introduction: An ongoing national multicenter survey [Italian Oncologic Pain multiSetting Multicentric Survey (IOPS-MS)] is evaluating the characteristics of breakthrough cancer pain (BTP) in different clinical settings. Preliminary data from the first 1500 cancer patients with BTP enrolled in this study are presented here. Methods: Thirty-two clinical centers are involved in the survey. A diagnosis of BTP was performed by a standard algorithm. Epidemiological data, Karnofsky index, stage of disease, presence and sites of metastases, ongoing oncologic treatment, and characteristics of background pain and BTP and their treatments were recorded. Background pain and BTP intensity were measured. Patients were also questioned about BTP predictability, BTP onset (≤10 or >10 min), BTP duration, background and BTP medications and their doses, time to meaningful pain relief after BTP medication, and satisfaction with BTP medication. The occurrence of adverse reactions was also assessed, as well as mucosal toxicity. Results: Background pain was well controlled with opioid treatment (numerical rating scale 3.0 ± 1.1). Patients reported 2.5 ± 1.6 BTP episodes/day with a mean intensity of 7.5 ± 1.4 and duration of 43 ± 40 min; 977 patients (65.1%) reported non-predictable BTP, and 1076 patients (71.7%) reported a rapid onset of BTP (≤10 min). Higher patient satisfaction was reported by patients treated with fast onset opioids. Conclusions: These preliminary data underline that the standard algorithm used is a valid tool for a proper diagnosis of BTP in cancer patients. Moreover, rapid relief of pain is crucial for patients’ satisfaction. The final IOPS-MS data are necessary to understand relationships between BTP characteristics and other clinical variables in oncologic patients. Funding: Molteni Farmaceutici, Italy
