Abstract
PURPOSE Stereotactic body radiation therapy has been used for prostate cancer. However, the bulk of published studies on stereotactic body radiation therapy for prostate cancer has involved the irradiation of the prostate alone, without irradiation of the pelvic lymph nodes. We report our preliminary experience with this approach. MATERIAL AND METHODS The files of patients with biopsy-proven prostate cancer treated with stereotactic body radiation therapy in our institution were reviewed. Stereotactic body radiation was delivered with intensity modulated-volumetric arctherapy with daily image-guidance. The prostate planning target volume included the prostate plus a margin of 5mm in all directions. The pelvic planning target volume included pelvic nodes plus an expansion of 6 to 7mm in all directions. The prostate planning target volume received a total dose of 36.25Gy delivered in five fractions on alternate days. The nodal planning target volume received a dose of 25Gy in the same five fractions. Patients were followed during treatment, after 1, and 3 months and every 6 months thereafter. Gastrointestinal and genitourinary toxicity was prospectively graded according to Common Terminology Criteria for Adverse Events. RESULTS Among the 188 patients, 80 received stereotactic body radiation to the prostate and the pelvic nodes, while 108 received stereotactic body radiation to the prostate target only. Grade 2 acute gastrointestinal toxicity was 4% in both groups, and grade 2 acute genitourinary toxicity was 27% and 20% (P=0.9) for prostate only versus prostate and pelvis respectively. There was no grade 3 or higher acute gastrointestinal or genitourinary toxicity. CONCLUSION Stereotactic body radiation therapy in five fractions including the prostate and pelvic nodes, in patients with high-risk prostate cancer, has been feasible and safe in terms of acute toxicity.

Abstract
PURPOSE/OBJECTIVE(S) Hypofractionated and stereotactic body radiotherapy (SBRT) are increasingly used in the treatment of centrally located, early-stage non-small cell lung cancer (NSCLC), though there are concerns of increased morbidity and mortality in patients with ultracentral tumors (UC). We report on the long-term toxicity of patients with UC lung cancer treated on a prospective randomized clinical trial of SBRT versus conventionally hypofractionated radiotherapy (CRT) for stage I NSCLC (NCT01968941). MATERIALS/METHODS Patients with UC tumors, defined as those where the planning target volume directly overlaps with the proximal bronchial tree (PBT), were identified from the larger cohort of patients treated on the trial. These patients received either SBRT with 60 Gy in 8 fractions or CRT with 60 Gy in 15 fractions. The primary endpoint of this secondary analysis was development of any grade 3 or higher toxicity defined using CTCAE version 3.0. Secondary endpoints included local control, as well as dosimetric analysis of the PBT, using EQD2 with α/β ratio of 3 to assess the relationship between dose to the PBT and toxicity. RESULTS Twenty-nine patients were identified with UC tumors; 21 received SBRT and 8 received CRT. Median age was 72 years (range 55-88 years) and 59% were female. Median FEV1 was 1.46L (range 0.64-2.37L). Patients had either T1 (59%) or T2 (41%) lesions, with median tumor size 2.5cm (range 1.1-4.9cm). Most patients had histologically confirmed disease (squamous cell, n = 10; adenocarcinoma, n = 8; radiographically suspicious, n = 11). The median follow-up was 2.9 years (range 0.7-5.2 years). The 3-year local control rate of all patients was 88.3% (95% confidence interval: 75.7-100%). There were 3 patients with late (>3 months) grade 3 toxicity (bronchial stricture, chest pain, and atelectasis) and 1 patient with late grade 5 toxicity (bleeding/hemorrhage), all treated in the SBRT arm. Median EQD2 dose to PBT in patients with grade ≥3 late toxicity compared to the rest of the cohort was: Dmax, 132 vs 129 Gy; D0.1cc, 129 vs 119 Gy; D1cc, 124 vs 80 Gy; and D5cc, 83 vs 41 Gy. Median EQD2 volumetric doses in grade ≥3 patients (compared to the rest) to PBT were: V65 Gy, 9.7 vs 2.2cc; V80 Gy, 7.9 vs 1.1cc; V90 Gy, 6.2 vs 0.4cc; and V100 Gy, 4.8 vs 0.3cc. The single patient with grade 5 toxicity had the highest D5cc (116 Gy) and V100 Gy (7cc) among all patients. CONCLUSION Stereotactic radiation with 60 Gy in 8 fractions for UC lung cancer provides good local control but carries an approximately 15-20% rate of late grade ≥3 toxicity. There appears to be a dosimetric association between toxicity and dose to the PBT. It may be more important to minimize volumetric PBT dose rather than maximum point dose to reduce risk of severe late toxicity.

Abstract
PURPOSE/OBJECTIVE(S) The standard of care for unresectable stage III non-small cell lung cancer (NSCLC) patients not candidates for concurrent chemotherapy (CT) and radiotherapy (RT) is not well established. Hypofractionated RT (hRT) can be used after CT induction, or, as a bridge to sequential CT to offer a curative intent treatment regimen. Tumor and nodal proximity to mediastinal structures plays an important role regarding the degree of safe hypofractionation. There is limited published evidence related the benefits of hRT combined with induction or sequential CT among this group of patients. We analyzed the outcomes of stage III NSCLC receiving a hRT regimen of 52.5 Gy in 15 fractions alone, or with either induction or sequential CT. MATERIALS/METHODS In this retrospective review, patients with stage III NSCLC receiving hRT 52.5 Gy in 15 fractions between 2008 and 2020 were included for analysis. Patients were separated into three cohorts: i) hRT alone, ii) induction CT followed by hRT, and iii) hRT followed by sequential CT. Overall survival (OS) and radiation toxicity (CTCAE v5.0) were analyzed for all 3 cohorts. Patients for whom sequential chemotherapy was planned, but not delivered, were included in cohort ii) through intention-to-treat analysis. The OS at 2 years was statistically evaluated using a log-rank test with alpha set at 0.05. RESULTS Eighty-three patients met criteria for analysis with 35, 30, and 18 patients respectively in cohorts i), ii), and iii). Median age at treatment was 75 (43-91) with 53% of patients being men and 43% women. Tumor histology varied between adenocarcinoma (43%), squamous cell carcinoma (44%), and others (13%). The median/2-year OS for cohorts i), ii), and iii) was 8 mo/19%, 25 mo/50%, and 17 mo/72% respectively. OS between any chemotherapy and no chemotherapy was statistically significant (p = 6.1x10-7) while the timing of chemotherapy did not reach statistical significance (p = 0.15). RT was overall well tolerated with grade 1-2 fatigue being the most common side effect (81%), 1 patient had grade 3 pneumonitis, and 1 patient had a rib fracture. CONCLUSION Among patients with stage III NSCLCs, moderately hRT of 52.5 Gy in 15 fractions, with either induction or sequential CT appears to provide a survival advantage compared to hRT alone, with an acceptable side-effect profile. The 2-year OS reported here is similar to other published hRT regimens (SOCCAR trial) and conventional fractionation (RTOG0617). Conclusions are limited by the retrospective nature of the study, and the introduction of immunotherapy (IO) for stage III NSCLC in 2019 in Canada. Future work will focus on evaluating dosimetry, the impact of IO, and, patients not included in this analysis that also received this regimen (oligometastasis, locoregional failure, other stages).

Abstract
PURPOSE/OBJECTIVE(S) Report the quality of life (QOL) analysis of the SPPORT trial of men with a detectable prostate specific antigen (PSA) after prostatectomy for prostate cancer randomized to (Arm 1) salvage prostate bed radiotherapy (PBRT), (Arm 2) 4-6 months of short-term androgen deprivation therapy (STADT) + PBRT, and (Arm 3) pelvic lymph node radiotherapy (PLNRT) + STADT + PBRT. Primary analysis established a benefit of adding PLNRT and STADT to PBRT. There was higher short term but no statistically significant difference in long term adverse events with the exception of blood or bone marrow events. MATERIALS/METHODS QOL endpoints were assessed at baseline, 6 weeks after RT start, 1 and 5 years, including Expanded Prostate Cancer Index Composite (EPIC) (bowel, urinary, sexual, and hormonal domains), Hopkins Symptom Checklist (HSCL-25) (depressive symptoms), and the EuroQol (EQ-5D) (health state weights used in quality adjusted life years (QALYs). In addition to statistical significance, differences in scores were assessed using 0.5 standard deviation (SD) as the criterion for clinical importance. Difference among arms was assessed using pairwise t-tests, Fisher's exact test, and mixed effects regression modeling. To control for multiplicity, the p-value required for statistical significance is p<0.025. RESULTS Six hundred forty-four patients consented to QOL, about 210 on each arm. Baseline characteristics were not significantly different among arms: 81% were white and 54% <65 years. For EPIC, bowel domain scores decreased at 6 weeks post-RT then increased by years 1 and 5, although not to baseline levels. One clinically significant difference in bowel scores was Arm 3 vs. Arm 1 at 6 weeks. For the urinary domain, scores decreased at 6 weeks post-RT and remained below baseline at 1 and 5 years, but there were no significant differences among arms. For the sexual domain, there were statistically significant differences between arms at 6 weeks and 1 year with patients receiving STADT exhibiting poorer sexual QOL scores. By year 5 the differences were no longer significant. A similar pattern was seen for the hormonal domain. For HSCL-25, differences at 6 weeks were statistically but not clinically significant, and there were no significant differences at the later time points. Comparisons of QALYs for overall survival over an 8-year horizon showed no significant group differences, with a mean of about 7.8 in each arm. Regarding freedom from progression, QALY means were 5.7, 6.5, and 7.4 years for Arms 1, 2, and 3, respectively, with a significant difference between Arms 3 and 1 (p = <.001) favoring the more intensive treatment. CONCLUSION While QOL generally declined among all arms at 6 weeks post RT, there were no clinically significant differences in QOL among arms at 5 years. QALYs for freedom from progression favored STADT + PLNRT + PBRT for salvage treatment of prostate cancer.

Abstract
AIM To investigate the influence of glycemic variability (GV) on length of stay and in-hospital mortality in non-critical diabetic patients. METHODS A observation retrospective study was performed. Diabetic patients admitted between January and June 2016 with the diagnosis of community-acquire pneumonia (CAP) and/or acute exacerbation of chronic obstructive pulmonary disease (COPD) were enrolled and glycemic control (persistent hyperglycemia, hypoglycemia, mean glucose level (MGL) and respective standard deviation (SD) and coefficient of variation (CV)) were evaluated. Primary outcomes were length of stay and in-hospital mortality. RESULTS Data from 242 patients were analyzed. Fifty-eight percent of the patients were male, with a median age of 77 years (min-max, 29-98). Patients had on average 2.1 glucose readings-day and the MGL was 193.3 mg/dl (min-max, 84.3-436.6). Hypoglycemia was documented in 13.4% of the patients and 55.4% had persistent hyperglycemia. The median length of hospital stay was 10 days (min-max, 1-66) and in-hospital mortality was 7.4%. We found a significant higher in-hospital mortality in older patients, with history of cancer and with nosocomial infections. We did not find any correlation between MGL, SD, CV, hypoglycemia or persist hyperglycemia and in-hospital mortality. A longer length of stay was observed in patients with heavy alcohol consumption and nosocomial infections. The length of stay was negatively correlated with the mean glucose level (r2-0.147; p < 0.05) and positively correlated with the coefficient of variation (p 0.162; p < 0.05). CONCLUSION This study confirmed the negative impact of the glycemic variability in the outcomes of diabetic patients admitted with CAP or acute exacerbation of COPD.

Abstract
Heart auscultation is one of the basic exams performed during a patient physical examination, but it is also one that has a high skill ceiling. Decision support systems can provide physicians with a tool that can help to reduce the demanding skill requirements of this exam. Nevertheless, this second opinion needs to be delivered in a timely interval in order to be truly useful for a physician. To do this we need not only optimized algorithms, but also a well designed system. In this paper, we have studied how two different data exchange protocols, that define how data should be transferred from an acquisition to a process module, can impact the celerity of delivering second opinion to a physician. With data collected from real exams, acquired in a field hospital initiative in Brazil, we recreated two use cases that allowed us to measure performance in the form of time and resources spent, as well as power consumption. Results have shown that different data exchange protocols can have a significant impact on a decision support system response time.

Abstract
Auscultation is currently both a powerful screening tool, providing a cheap and quick initial assessment of a patient's clinical condition, and a hard skill to master. The teaching of auscultation in Universities is today reduced to an unsuitable number of hours. Virtual patient simulators can potentially mitigate this problem, by providing an interesting high-quality alternative to teaching with real patients or patient simulators. In this paper we evaluate the pedagogical impact of using a virtual patient simulation technology in a short workshop format for medical students, training them to detect cardiac pathologies. Results showed a significant improvement (+16%) in the differentiation between normal and pathological cases, although longer duration formats seem to be needed to accurately identify specific pathologies.

Abstract
AIM A prospective phase II study to investigate the feasibility and the rate of complete pathological response (ypT0) after short-course radiotherapy (SCRT) followed by surgery at 8 weeks. METHOD Operable patients with localized rectal cancer staged T3-4N0/+ or T2N+ were eligible and received 25 Gy (in one-third of patients, the gross tumor volume received a simultaneous integrated boost up to a total of 30 Gy) in five consecutive fractions to the posterior pelvis followed by surgery 8 weeks later. Pathological response and surgical toxicity were assessed in all patients. RESULTS Fifty-two patients (median age 68 years) completed the study. The median distance of the tumour from the anal verge was 6.5 cm. The median interval to surgery was 52 days. Three-quarters of patients underwent a low anterior resection. All underwent complete surgical resection and 100% had pathological negative margins. Ten per cent had stage ypT0 after radiotherapy. The median length of hospital stay was 8 days. Toxicity was comparable with the rates reported in the literature. CONCLUSION In this study, SCRT followed by delayed surgery was feasible and had acceptable toxicity. All patients underwent complete surgical resection and 100% had negative pathological margins. The rate of ypT0 was 10%.

Abstract
To understand the role of chitosan in chitosan-poly(butylene succinate) scaffolds (50% wt), 50%, 25%, and 0% of chitosan were used to produce different scaffolds. These scaffolds were in vitro seeded and cultured with human bone marrow stromal cells in osteogenic conditions, revealing that higher percentage of chitosan showed enhanced cell viability over time, adhesion, proliferation, and osteogenic differentiation. Scaffolds were also implanted in cranial defects and iliac submuscular region in Wistar rats, and the results evidenced that chitosan-containing scaffolds displayed mild inflammatory response and good integration with surrounding tissues, showed by connective tissue colonization and the presence of new blood vessels. Scaffolds without chitosan-evidenced necrotic tissue in scaffolds' interior, proving that chitosan exerts a positive effect over cell behavior and displays a milder host inflammatory response in vivo.

Abstract
Paracrine signalling from chondrocytes has been reported to increase the synthesis and expression of cartilage extracellular matrix (ECM) by stem cells. The use of conditioned medium obtained from chondrocytes for stimulating stem cells chondrogenic differentiation may be a very interesting alternative for moving into the clinical application of these cells, as chondrocytes could be partially replaced by stem cells for this type of application. In the present study we aimed to achieve chondrogenic differentiation of two different sources of stem cells using conditioned medium, without adding growth factors. We tested both human bone marrow-derived mesenchymal stem cells (hBSMCs) and human Wharton's jelly-derived stem cells (hWJSCs). Conditioned medium obtained from a culture of human articular chondrocytes was used to feed the cells during the experiment. Cultures were performed in previously produced three-dimensional (3D) scaffolds, composed of a blend of 50:50 chitosan:poly(butylene succinate). Both types of stem cells were able to undergo chondrogenic differentiation without the addition of growth factors. Cultures using hWJSCs showed significantly higher GAGs accumulation and expression of cartilage-related genes (aggrecan, Sox9 and collagen type II) when compared to hBMSCs cultures. Conditioned medium obtained from articular chondrocytes induced the chondrogenic differentiation of MSCs and ECM formation. Obtained results showed that this new strategy is very interesting and should be further explored for clinical applications.

Abstract
Stress is a major factor for the degradation of cardiac health in first responder professionals such as firefighters. Monitoring stress during real events might be the key for controlling this problem. In this paper we inspect how standard heart rate variability (HRV) measures are associated with the self-perception of stress of firefighters in action, supported by an advanced technological solution to acquire this data. Results obtained from more than 94 hours of annotated ECG recordings of firefighters in action are promising, showing positive association with various standard HRV measures. Given the richness of the gathered data, we have also measured the association of the HRV measures with the stage of a firefighting event (pre, during, post), obtaining some interesting results that hint that the psychological impact of the post-event may be one of the most concerning situations for a firefighter, motivating further studies on this in the future.

Abstract
In May 2003, investigators were trained and prevalence pilot study was conducted at the University Hospital of Tirana, Albania. Investigators were trained to assess the organizational problems of the first prevalence survey of nosocomial infections (NIs) in Albania. Twelve investigators were trained in 2 days. After the training, the pilot study was conducted in 3 wards. The investigators collected data using a standard form and the definitions of the Centers for Disease Control, USA. The training improved the investigators' knowledge of NI epidemiology and surveillance. The pilot study underlined the lack of information in the clinical documentation and lack of collaboration between clinicians and the laboratory: microbiological examinations were performed only in 13 (16.5%) patients and none of the 11 NIs reported was confirmed in the laboratory. This led to a review of the survey protocol, above all in order to increase the use of microbiological laboratory.

Abstract
IntroductionPeople with mental illness are frequently perceived as dangerous, suffering social stigma and exclusion. Deinstitutionalization movement implies a closer contact between citizen and individuals with mental illness. However, social perceptions can be a barrier to social inclusion, provoking unfavorable attitudes. Some studies found that social rejection is different according the pathology. Vogel and Boysen (2008) found that different mental illnesses provoke different attitudes of social distance. Norman and colleagues (2008) found that social distance was associated with the diagnosis, provoking schizophrenia greater social distance than depression.AimsCompare the perceptions about mental illness (in general), depression, bipolar disorder and schizophrenia.MethodsData were collected using a translation of Mental Illness Stigma Scale (Day, 2007), fulfill on-line and in an anonym way by 315 Portuguese polytechnic students, studying in brief technological courses. The sample was composed by 69% male and 31% female; mean age 26.5 years.ResultsStudents have little contact with people with mental illness (mean = 1.5 in a Likert scale 1–5 points) but they fell comfortable when they contact a friend or a neighbor with mental illness (respectively, mean = 3.2 and mean = 2.7). They present some anxiety when they interact with people with mental illness and they avoid this contact, revealing attitudes of social exclusion. Schizophrenia and bipolar disorder was perceived more negatively than depression.ConclusionsDeinstitutionalization movement provokes more contact between citizens and individuals with mental illness, but social stigma still exist. Students can learn how to interact with those persons without anxiety and help to do better social inclusion.

Abstract
83 Background: We present the long-term results of a cohort of patients with intermediate-risk prostate cancer (PC) treated with single fraction high-dose-rate brachytherapy (HDRB) combined with hypofractionated external beam radiation therapy (HRT). Methods: Patients with intermediate-risk PC were treated exclusively with HDRB and HRT. HDRB delivered a dose of 10 Gy to the prostate gland and HRT consisted of 50 Gy delivered in 20 daily fractions. The planning target volume was the prostate gland with a 1 cm margin all around. The first 121 consecutive patients with a minimum of 2 years post-treatment follow-up were assessed for acute and chronic toxicity and disease control. Results: The median follow-up was 62.8 months. No acute grade III or higher toxicities were seen. Grade II late GI toxicity was seen in 9 patients (7.4%) and grade III in 2 (1.6%). Grade 3 GU toxicity was seen in 2 patients (1.6%), both with urinary obstructive symptoms requiring catheterization. A repeat biopsy was offered to the first 58 consecutively treated patients, and 44 patients agreed with the procedure. A negative biopsy was found in 40 patients (91%). The biochemical relapse-free survival rate at 5 and 8 years were 90.7% and 81.4%, with 13 patients presenting biochemical failure. Among them, nine were diagnosed with distant metastasis. Prostate cancer-specific and overall survival rates at 8 years were 100% and 95.5%, respectively. Conclusions: Our program of HDRB and HRT is well tolerated, with acceptable toxicity rates. Furthermore, results from re-biopsies revealed an elevated rate of local control. These results are encouraging and confirm that the use of conformal RT techniques, adapted to specific biological features, have the potential to improve the therapeutic ratio in intermediate risk PC patients. No significant financial relationships to disclose.

Abstract
93 Background: A wide range of therapeutic alternatives is available for the treatment of intermediate-risk prostate cancer (IRPC). The use of hypofractionated external beam radiotherapy (HypoRT) in this group of patients appears to be an attractive option. Non-randomized institutional results have provided similar outcomes to conventional fractionation. For health-systems such as we have in Canada, where many patients live far, it significantly shortens treatment duration and impacts favorably in health costs. We report our results using HypoRT alone in IRPC. Methods: Between October/2002 and July/2009, 82 men with IRPC (T2b-T2c, or PSA 10–20 ng/dL, or GS=7) were treated with HypoRT, without any androgen deprivation. Ultrasound image guidance was used daily to confirm setup. The dose was 66 Gy in 22 daily fractions of 3 Gy (BED=79.4Gy/44) prescribed at the isocenter. PTV was the prostate (+/− 1cm seminal vesicles) with 7-mm margin in all directions. GI and GU toxicity were prospectively assessed every 4–6 months using the CTCAE v3 scoring system. Biochemical failure was defined as nadir PSA + 2 ng/dL. Results: 60% of patients had Gleason score 7; 43% had stage T2; median initial PSA=9 ng/ml; median age 71 years. With a median follow-up of 43 months (range: 7–89), only three patients (4%) have developed biochemical failure. All three showed metastatic disease few months after biochemical failure. Actuarial biochemical recurrence free survival (bNED) is 95.4%. There was no death related to prostate cancer. Three patients died from other causes without biochemical failure. The 5-year overall survival was 93%. At the last follow up visit, grade ≥ 2 late GI and GU toxicity rates were 2% and 7%, respectively. No grade 4 or 5 has occurred. Conclusions: Men with IRPC treated with 66Gy/22 fractions and without androgen deprivation have experienced excellent 5-year biochemical control rate with acceptable late toxicity. This regimen is very convenient because the duration of the treatment is half of the time used with conventional fractionation. Whether the addition of short-term androgen deprivation would further improve outcome remains unclear. No significant financial relationships to disclose.
