Abstract
BACKGROUND Soft tissue sarcomas are rare malignant tumors with significant heterogeneity. The importance of classifying histological grades is fundamental to defining the treatment approach. OBJECTIVE To evaluate magnetic resonance imaging (MRI) in predicting the histological grade of soft tissue sarcomas. METHODS A retrospective observational study included patients over 18 years undergoing MRI and primary tumor surgery at AC Camargo Cancer Center from January 2015 to June 2022. Two radiologists evaluated MRI criteria (size, margin definition, heterogeneity of the T2 signal, high-intensity peritumoral signal on T2, and postperitumoral contrast), and a grading prediction score was calculated. χ2 and logistic regression analyses were conducted. RESULTS Sixty-eight patients were included (38 men; median: 48 years). Moreover, 52 high-grade and 16 low-grade tumors were observed. The MRI criteria associated with histological grade were peritumoral high-intensity T2-weighted signals (p < 0.001) and peritumoral postcontrast enhancement (p = 0.006). Logistic regression confirmed their significance (odds ratio [OR]: 11.8 and 8.8, respectively). Each score point increment doubled the chance of high-grade tumors (OR: 2.0; p = 0.014). CONCLUSION MRI effectively predicts histological grades of soft tissue sarcomas. Peritumoral high-intensity T2-weighted signals and peritumoral postcontrast enhancement are valuable indicators of high-grade tumors. This highlights MRI's importance in treatment decision-making for sarcoma patients.

Abstract
Summary Background. The clinical and pathophysiological heterogeneity of atopic dermatitis (AD) endophenotypes is associated with wide diversity in response to therapy. The aim of this study was to evaluate the response to dupilumab in a group of AD patients and identify clinical/immunological features associated with different patterns of response. Methods. A retrospective observational study was performed, including 30 adults with AD who completed 12 months treatment with dupilumab, in a Portuguese Immunoallergology Department. Demographic, clinical, and immunological data were analyzed, including total serum IgE, sensitization to aeroallergens, peripheral eosinophilia and inflammatory biomarkers (sedimentation rate, C-reactive protein and lactate dehydrogenase-LDH). Patients who achieved EASI-75/EASI ≤ 7, SCORAD-75/SCORAD ≤ 24, NRS-pruritus ≤ 4 or DLQI≤5 at 6 months of treatment were considered responders and those that achieved all these goals at 16 weeks were considered super-responders. Results. Clinical evaluation revealed a significant reduction in median SCORAD, EASI, DLQI, NRS-pruritus and NRS-sleep over 12 months on dupilumab (p less than 0.01), in parallel with decrease in serum Th2 pathway biomarkers and LDH. All patients responded to dupilumab, and 26.7% were super-responders, supporting that dupilumab is highly effective in moderate to severe Th2-high AD. Conclusions. In this cohort, none of the evaluated biomarkers at baseline were associated with a better/earlier clinical response to dupilumab. Dupilumab treatment for 52 weeks resulted in a significant and sustained reduction in blood levels of total IgE and allergen-specific IgE to aeroallergens. The potential long-term clinical benefit of these effects, even after discontinuing dupilumab therapy in patients with AD, should be explored to a greater extent.

Abstract
BACKGROUND The bed nucleus of the stria terminalis (BNST) is a structure with a peculiar neurochemical composition involved in modulating anxietylike behavior and fear. AIM The present study investigated the effects on the BNST neurochemical composition and neuronal structure in critical moments of the postnatal period in gestational protein-restricted male rats' offspring. METHODS Dams were maintained during the pregnancy on isocaloric rodent laboratory chow with standard protein content [NP, 17%] or low protein content [LP, 6%]. BNST from male NP and age-matched LP offspring was studied using the isotropic fractionator method, Neuronal 3D reconstruction, dendritic-tree analysis, blotting analysis, and high-performance liquid chromatography. RESULTS Serum corticosterone levels were higher in male LP offspring than NP rats in 14-day-old offspring, without any difference in 7-day-old progeny. The BNST total cell number and anterodorsal BNST division volume in LP progeny were significantly reduced on the 14th postnatal day compared with NP offspring. The BNST HPLC analysis from 7 days-old LP revealed increased norepinephrine levels compared to NP progeny. The BNST blot analysis from 7-day-old LP revealed reduced levels of GR and BDNF associated with enhanced CRF1 expression compared to NP offspring. 14-day-old LP offspring showed reduced expression of MR and 5HT1A associated with decreased DOPAC and DOPA turnover levels relative to NP rats. In Conclusion, the BNST cellular and neurochemical changes may represent adaptation during development in response to elevated fetal exposure to maternal corticosteroid levels. In this way, gestational malnutrition alters the BNST content and structure and contributes to already-known behavioral changes.

Abstract
Rare sarcomas present significant treatment challenges compared to more prevalent soft tissue sarcomas due to limited treatment options and a poor understanding of their biology. This study investigates a unique case of penile sarcoma, providing a comprehensive morphological and molecular analysis. Through the creation of experimental patient-derived models-including patient-derived xenograft (PDX), 3D, and monolayer primary cultures-we successfully replicated crucial molecular traits observed in the patient's tumor, such as smooth muscle actin and CD99 expression, along with specific mutations in genes like TSC2 and FGFR4. These models are helpful in assessing the potential for an in-depth exploration of this tumor's biology. This comprehensive approach holds promise in identifying potential therapeutic avenues for managing this exceedingly rare soft tissue sarcoma.

Abstract
Introduction: Rare disorders that are genetically and clinically heterogeneous, such as mitochondrial diseases (MDs), have a challenging diagnosis. Nuclear genes codify most proteins involved in mitochondrial biogenesis, despite all mitochondria having their own DNA. The development of next-generation sequencing (NGS) technologies has revolutionized the understanding of many genes involved in the pathogenesis of MDs. In this new genetic era, using the NGS approach, we aimed to identify the genetic etiology for a suspected MD in a cohort of 450 Portuguese patients. Methods: We examined 450 patients using a combined NGS strategy, starting with the analysis of a targeted mitochondrial panel of 213 nuclear genes, and then proceeding to analyze the whole mitochondrial DNA. Results and Discussion: In this study, we identified disease-related variants in 134 (30%) analyzed patients, 88 with nuclear DNA (nDNA) and 46 with mitochondrial DNA (mtDNA) variants, most of them being pediatric patients (66%), of which 77% were identified in nDNA and 23% in mtDNA. The molecular analysis of this cohort revealed 72 already described pathogenic and 20 novel, probably pathogenic, variants, as well as 62 variants of unknown significance. For this cohort of patients with suspected MDs, the use of a customized gene panel provided a molecular diagnosis in a timely and cost-effective manner. Patients who cannot be diagnosed after this initial approach will be further selected for whole-exome sequencing. Conclusion: As a national laboratory for the study and research of MDs, we demonstrated the power of NGS to achieve a molecular etiology, expanding the mutational spectrum and proposing accurate genetic counseling in this group of heterogeneous diseases without therapeutic options.

Abstract
INTRODUCTION The management of giant cell arteritis (GCA) has evolved with the arrival of tocilizumab (TCZ) and the use of PET/CT. Our objective is to describe the characteristics and followup of patients with recent diagnosis of GCA in current care. PATIENTS AND METHODS The NEWTON cohort is a monocentric retrospective cohort based on data collected from 60 GCA patients diagnosed between 2017 and 2022 according to the ACR/EULAR 2022 criteria. RESULTS The median age at diagnosis was 73 [68.75; 81] years old. At diagnosis, the main manifestations were unusual temporal headaches in 48 (80 %) and an inflammatory syndrome in 50 (83 %) patients. Temporal artery biopsy confirmed the diagnosis in 49/58 (84 %) patients. Doppler of the temporal arteries found a halo in 12/23 (52 %) patients. The PET/CT found hypermetabolism in 19/43 (44 %) patients. Prednisone was stopped in 17.5 [12.75; 24.25] months. During follow-up, 22 (37 %) patients received TCZ. At least one complication of corticosteroid therapy was observed in 22 (37 %) patients. After a median follow-up of 24 [12; 42] months, 25 (42 %) patients relapsed. At the end of the follow-up, 29 (48.3 %) patients were weaned from corticosteroid therapy and 15 (25 %) were on TCZ. CONCLUSION Despite the increasing use of TCZ in the therapeutic arsenal and of the PET/CT in the imaging tools of GCA patients, relapses and complications of corticosteroid therapy remain frequent, observed in more than a third of patients.

Abstract
Summary Background. Metamizole, a non-steroidal anti-inflammatory drug from the pyrazolone group, is a frequent cause of immediate hypersensitivity reactions and, more rarely, of delayed drug hypersensitivity reactions. Due to its favorable pharmacokinetic characteristics, metamizole is widely used in the postoperative period for pain control. Methods. Retrospective study of patients referred for allergological study between January 2012 and June2022 for postoperative hypersensitivity reactions. Clinical and diagnostic data were collected through review of patients' medical records. Twenty patients with postoperative hypersensitivity reactions were referred, of which 10 presented delayed reactions. We analyzed the results of skin prick, intradermal and patch tests performed with an intravenous metamizole solution as well as provocation tests performed with metamizole and acetylsalicylic acid. Cross-reactivity to non-steroidal anti-inflammatory drugs was excluded by confirmation of clinical tolerance to non-steroidal anti-inflammatory drugs or by acetylsalicylic acid provocation test. Results. In 7 of the 10 patients a delayed reaction to metamizole was diagnosed. These reactions were characterized as maculopapular exanthema, occurring in multiple postoperative settings. Skin tests were negative, except in one patient with late mild erythema in the ipsilateral upper limb and no reaction at the site of intradermal injection. Delayed hypersensitivity was demonstrated by late positive metamizole provocation tests. Conclusions. This study demonstrated that for a correct diagnosis a high degree of suspicion about possible delayed hypersensitivity drug reactions to metamizole in the postoperative setting is needed. In the investigation, provocation test with metamizole was decisive for diagnostic confirmation.

Abstract
BACKGROUND The initial approach to the treatment of desmoid tumors has changed from surgical resection to watchful waiting. However, surgery is still sometimes considered for some patients, and it is likely that a few patients would benefit from tumor removal if the likelihood of local recurrence could be predicted. However, to our knowledge, there is no tool that can provide guidance on this for clinicians at the point of care. QUESTION/PURPOSE We sought to explore whether a combined molecular and clinical prognostic model for relapse in patients with desmoid tumors treated with surgery would allow us to identify patients who might do well with surgical excision. METHODS This was a retrospective, single-center study of 107 patients with desmoid tumors who were surgically treated between January 1980 and December 2015, with a median follow-up of 106 months (range 7 to 337 months). We correlated clinical variables (age, tumor size, and localization) and CTNNB1 gene mutations with recurrence-free survival. Recurrence-free survival was estimated using a Kaplan-Meier curve. Univariate and multivariable analyses of time to local recurrence were performed using Cox regression models. A final nomogram model was constructed according to the final fitted Cox model. The predictive performance of the model was evaluated using measures of calibration and discrimination: calibration plot and the Harrell C-statistic, also known as the concordance index, in which values near 0.5 represent a random prediction and values near 1 represent the best model predictions. RESULTS The multivariable analysis showed that S45F mutations (hazard ratio 5.25 [95% confidence interval 2.27 to 12.15]; p < 0.001) and tumor in the extremities (HR 3.15 [95% CI 1.35 to 7.33]; p = 0.008) were associated with a higher risk of local recurrence. Based on these risk factors, we created a model; we observed that patients considered to be at high risk of local recurrence as defined by having one or two factors associated with recurrence (extremity tumors and S45F mutation) had an HR of 8.4 compared with patients who had no such factors (95% CI 2.84 to 24.6; p < 0.001). From these data and based on the multivariable Cox models, we also developed a nomogram to estimate the individual risk of relapse after surgical resection. The model had a concordance index of 0.75, or moderate discrimination. CONCLUSION CTNNB1 S45F mutations combined with other clinical variables are a potential prognostic biomarker associated with the risk of relapse in patients with desmoid tumors. The developed nomogram is simple to use and, if validated, could be incorporated into clinical practice to identify patients at high risk of relapse among patients opting for surgical excision and thus help clinicians and patients in decision-making. A large multicenter study is necessary to validate our model and explore its applicability. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
PURPOSE/OBJECTIVE(S) Acute severe diarrhea is a common toxicity in rectal cancer patients receiving CRT. A better understanding of the radiation tolerance of the small bowel is needed especially for novel radiation drug combinations. We investigate the dose impact by providing auto-contoured small bowel, using data from the ARISTOTLE phase III trial ISRCTN: 09351447. MATERIALS/METHODS A subset of participants (n = 93/564) with locally advanced rectal cancer in the ARISTOTLE trial testing the addition of concurrent irinotecan (n = 48) to neoadjuvant capecitabine (n = 45) CRT (45/25 Gy/fx), in an MRI defined high risk of loco-regional failure. CRT was delivered with conformal techniques. Diarrhea was measured using CTCAE v4.0 weekly. We applied an AI-based auto-contouring model to segment the small bowel on planning CT. The small-bowel DVH parameters were combined with the treatment arm, age, sex and MRI-defined tumor stage in a linear regression (LR) model to predict acute diarrhea severity. Explainable Shapley values (conditional marginalized expectation of a machine learning model per feature) were used to quantify the independent and normalized impact of radiation dose vs Irinotecan on the likelihood of severe diarrhea. RESULTS The auto-contouring model accuracy was consistent with clinical practice (mean dice coefficient = 0.739) and clinically acceptable when reviewed by clinicians. The treatment arm, MRI-defined T stage and small-bowel mean dose were found to be independently correlated to the diarrhea severity (p<0.001). V30Gy showed the strongest correlation to diarrhea severity in all the DVH parameters. The LR using the three variables yielded mean AUC scores of 0.898 (95% CI: [0.831,0.958]) on predicting Grade 2 and higher diarrhea, and 0.774 (95% CI: [0.678,0.869]) on predicting Grade 3 diarrhea based on 10-fold cross-validation. Shapley values showed that V30Gy>30.56 cm3 increases the likelihood of more severe diarrhea against the average (grade = 1.03) in the cohort. The impact of irradiation will be larger than the usage of Irinotecan within the patients with V30Gy >160.93 cm3. CONCLUSION We accurately modelled acute diarrhea (AUC = 0.90) for rectal cancer patients receiving CRT using AI-contoured small-bowel structures. The treatment arm and small-bowel dose were independently correlated to the diarrhea severity. The explainable model allowed us to quantify the impact of radiation dose, usage of irinotecan, and its combination, with a threshold of V30Gy = 160.93 cm3 yielding an equivalent impact. We will be extending the analysis to the whole trial cohort to improve the statistical power.

Abstract
Summary Background. Non-steroidal anti-inflammatory drugs (NSAID)/analgesics (paracetamol) are among the most common causes of drug hypersensitivity reactions in children, with a reported prevalence of around 0.3% in the pediatric population. Paracetamol and ibuprofen are the most commonly reported culprits in the pediatric population. Our objective was to describe the allergy workup to NSAID/paracetamol of a pediatric population monitored in an allergy outpatient clinic. Methods. Retrospective observational study by consulting the medical records of patients evaluated in a pediatric outpatient clinic with history of NSAID/paracetamol, between January 2016 to August 2022. Results. A total of 43 patients have been evaluated for NSAID/paracetamol suspected allergy: 53.5% females, mean age of 9.8 ± 5.1 years, 47.7% atopic. The drugs reported as culprits were: ibuprofen (75.6%), paracetamol (17.8%), metamizole (4.4%) and naproxen (2.2%) and clinical manifestations were mainly urticaria/angioedema and maculopapular exanthema. Skin tests were performed in 7 patients: paracetamol (n = 5) and metamizole (n = 2), which were all negative. Fourty-six drug provocation tests were performed: 28 with the culprit drug and 18 with an alternative one; only 2 were positive (ibuprofen - culprit NSAID group): one immediate periorbital angioedema and one delayed lip edema with oropharyngeal tightness. Conclusions. The investigation of allergy to NSAID/paracetamol in children remains a challenge. In our population, ibuprofen was the most common NSAID reported. There were only 2 (4.3%) mild reactions on DPT. We could allow the use of the culprit NSAID/analgesic in 11 patients and an alternative one in 9 patients. This study highlights the importance of DPT in children for a correct diagnosis of NSAID hypersensitivity and selection of an alternative drug.

Abstract
BACKGROUND Colorectal cancer (CRC) is a worldwide health problem whose control depends on public policy establishment and effective prevention and screening programs. In Brazil, there are few studies related to adherence to screening methods. AIMS The aim of this study was to evaluate the association between demographic and socioeconomic to adherence to CRC screening with fecal immunochemical test (FIT) among average-risk individuals for CRC. METHODS In this prospective cross-sectional study, conducted between March 2015 and April 2016, 1,254 asymptomatic individuals aged 50-75 years, participating in a hospital screening campaign in Brazil, were invited to participate in the study. RESULTS The adherence rate to FIT was 55.6% (697/1,254). In the multivariable logistic regression analysis, patients aged 60-75 years (odds ratio (OR)=1.30; 95% confidence interval (CI): 1.02-1.66; p=0.03), religious belief (OR=2.04; 95% CI: 1.34-3.11; p<0.01), previous fecal occult blood test (OR=2.07; 95% CI: 1.55-2.76; p<0.01), and full/part-time working status (OR=0.66; 95% CI: 0.49-0.89; p<0.01) were independently associated with adherence to CRC screening. CONCLUSION The results of the present study highlight the importance of considering the labor aspects when implementing screening programs, suggesting that campaigns conducted in the workplace and repeated over the years may be more effective.

Abstract
Summary Hereditary angioedema (HAE) poses a high burden of disease, being its epidemiological and clinical data heterogeneous among countries, with no recent published studies concerning Portuguese patients. Therefore, we aimed to raise awareness of HAE and to contribute to clinical knowledge. An observational, descriptive, retrospective, and cross-sectional study was performed, that included a cohort of 126 patients followed in a single Portuguese Center. We observed a high prevalence of HAE-C1-INH type II (45.2% of patients). Most HAE patients (67.4%) presented the initial manifestations of the disease before adulthood, at a mean age of 12.6 ± 8.4 years. However, we found a long delay in HAE diagnosis, especially in those without family history (mean 20.7 ± 17.3 years). Stress was the most common trigger, followed by trauma and infection. Symptoms involving different systems were increasingly reported with increased disease duration. Cutaneous symptoms (95.0%) were more frequent, followed by gastrointestinal (80.7%), and respiratory symptoms (50.4%). HAE symptoms led to abdominal surgery in 22 (17.5%) patients and induced laryngeal edema requiring intubation/tracheostomy in 8 (6.3%) patients. Most patients were under long-term prophylaxis, mainly with attenuated androgens (62.7% of patients).The correct distinction between HAE and other common causes of angioedema is critical, allowing reduction of diagnostic delay, improvement of adequate management, and ultimately improving outcomes and quality of life of HAE patients.

Abstract
Extracellular matrix (ECM) remodeling and inflammation have been reported in penile carcinomas (PeCa). However, the cell types and cellular crosstalk involved in PeCa are unexplored. We aimed to characterize the complexity of cells and pathways involved in the tumor microenvironment (TME) in PeCa and propose target molecules associated with the TME. We first investigated the prognostic impact of cell types with a secretory profile to identify drug targets that modulate TME-enriched cells. The secretome analysis using the PeCa transcriptome revealed the enrichment of inflammation and extracellular matrix pathways. Twenty-three secreted factors were upregulated, mainly collagens and matrix metalloproteinases (MMPs). The deregulation of collagens and MMPs was confirmed by Quantitative reverse transcription - polymerase chain reaction (RT-qPCR). Further, the deconvolution method (digital cytometry) of the bulk samples revealed a high proportion of macrophages and dendritic cells (DCs) and B cells. Increased DCs and B cells were associated with better survival. A high proportion of cancer-associated fibroblasts (CAFs) was observed in low-survival patients. Patients with increased CAFs had decreased immune cell proportions. The treatment with the MMP inhibitor GM6001 in CAF cells derived from PeCa resulted in altered cell viability. We reported a crosstalk between immune cells and CAFs, and the proportion of these cell populations was associated with prognosis. We demonstrate that a drug targeting MMPs modulates CAFs, expanding the therapeutic options of PeCa.

Abstract
e23527 Background: Extremity soft-tissues sarcomas are a rare entity that represent 1% of solid tumors in adults. Surgery is the main treatment and limb sparing resection with adjuvant radiotherapy (RT) is associated with good local control. However, high rates of distant relapses motivated the evaluation of adjuvant systemic treatment protocols. We aim to compare survival rates between two cohorts of patients treated with two different preoperative protocols. Methods: An observational comparative cohort study were carried out. Two cohorts of patients with high grade, larger then 5.0 cm, and non-metastatic soft tissue sarcomas of extremities, treated with two distinct preoperative institutional protocols, in two different periods of time, were compared. Group 1 included patients treated in the period from January, 1995 to December, 2004, when patients with high risk extremities soft tissue sarcomas were submitted to preoperative radiation therapy (a total dose of 30 Gy) concomitant with doxorubicin (60 mg/m2); this protocol included adjuvant chemotherapy with doxorubicin and ifosfamide. Group 2 included patients treated in the period from April, 2005 to July, 2012, when our group changed the preoperative protocol to neoadjuvant chemotherapy without radiation, with four cycles doxorubicin (60 mg/m2 per cycle) and ifosfamide (9.000 mg/m2 per cycle), followed by surgery, and postoperative radiation. Data from the group 1 were retrospectively collected, and data from group 2 were from our prospective database. Results: Eighty-eight patients were included (37 in group 1 and 51 in group 2). There were no statistical differences between the groups with regards to age, gender, location and tumor size. Predominant histological subtypes were synovial sarcoma (27.3%), pleomorphic sarcoma (15.9%), leiomyosarcoma (11.4%) and liposarcoma (8%). Relapses occurred in 60.5% of patients, most in the lungs (48.1%). Amputation rates were 14.3% in the group 1 and 4.5% in the group 2. Five-year local recurrence free survival was 81.7% for the group 1 and 91.7% for the group 2. There was no difference in median overall survival when comparing group 1 and 2 (47 versus 78 months, respectively; IC 95 3.967 – 132.033; p = 0.49), but our data showed higher recurrence free survival in group 2 (19 versus 132 months; IC 95 5.9 – 60.09; p = 0.025, respectively). Among patients from the group 2, whom presented less than 10% of viable tumor cells in the surgical specimens (good responders), no local or distant recurrences have occurred. Conclusions: In our retrospective analysis, neoadjuvant chemotherapy was associated with greater recurrence free survival in patients with high-grade extremity soft tissue sarcomas as compared to neoadjuvant chemoradiation. For patients with high risk of distant relapse, neoadjuvant chemotherapy should be considered after a multidisciplinary discussion.

Abstract
A fruit processing wastewater was submitted to different advanced oxidation processes, namely, electro-Fenton (EF), electrochemical oxidation (EO), activated persulfate (PS), and combined EF/PS. The performance of the treatment processes, at different experimental conditions, regarding organic load removal, biodegradability increment, toxicity reduction, and specific energy consumption (Esp), was evaluated. At the experimental conditions studied, EO led to the treated solutions with the highest biodegradability increment, from 0.24 to 0.48, and toxicity reduction towards Daphnia magna, from 5.8 to 1.5 toxic units, without requiring the addition of chemicals. Nevertheless, the highest chemical oxygen demand (COD) removals were obtained for EF and combined EF/PS treatments. For the electrochemical processes, an increase in COD removal rate with applied current density (j) was observed. However, the increase in j substantially raised the Esp. In PS treatment, COD removals above 80% were only achieved for high amounts of added persulfate and iron, which led to less biodegradable and more toxic solutions. Combined EF/PS attained the lowest Esp values, mainly due to the conductivity increase originated by the persulfate and iron salts addition. Besides the disadvantage of the chemicals added, this combined treatment led to treated solutions with very acidic pH and significant iron content.

Type of funding sources: None.
Background
Atrial fibrillation (AF) is the most common arrhythmia and one of the most frequent motives for presentation in the emergency department (ED). However, there are still significant inequalities concerning its treatment.
Purpose
We aimed to assess if management and outcomes of patients with AF differed according to the specialty to which they were referred at hospital discharge.
Methods
We conducted a retrospective single-centre analysis including adult patients admitted to the ED in 2016 with the International Classification of Diseases codes correspondent to AF. Patients older than 75 years and those whose electronic medical file was not accessible were excluded. Patient referral at discharge was not based on any pre-specified criteria but rather performed at the discretion of the physician in the ED.
We divided our sample into 3 groups according to whom the patients were referred at hospital discharge: A) patients referred to an electrophysiologist; B) patients referred to a general cardiologist; and C) those referred to a non-cardiologist (general practitioner or internist).
We assessed patient characteristics, delay to first appointment, treatment strategies as well as stroke and all-cause mortality at 3 years of follow-up.
Results
Of the 372 patients initially screened, 184 were excluded due to age over 75 and 85 patients due to inaccessible medical records, resulting in a final sample of 103 patients with a median age of 65 (58-71) years and median CHA2DS2-VASc of 2 (1-3).
At discharge from the index admission, one third of patients were referred to an electrophysiologist (group A), 41% to a general cardiologist (group B) and the remaining 26% to a non-cardiologist (group C). There were no significant differences in baseline characteristics or type of AF between the groups.
The delay from index hospital admission to the first appointment was superior in groups A and B compared with C (3 and 2 vs 0 months, p=0.050).
Patients referred to an electrophysiologist were more frequently started on a rhythm-control strategy compared with those referred to other physicians (71% vs 38% and 26%, p=0.004). Similarly, significantly more patients in group A underwent catheter ablation (47% vs 12% and 4%, p<0.001), around 2 years after the diagnosis (tendentially earlier than those in group B).
At 3 years follow-up, mortality was higher in group C compared with the other groups (15% vs 0 in group A and 2% in group B, p=0.019). Stroke rates did not differ between groups.
Conclusion
In this group of AF patients, referral to an electrophysiologist at discharge was associated with a higher rate of a rhythm-control strategy, including catheter ablation. In the long-term, those patients showed better survival. These results suggest that, in patients under 75 years, an earlier referral to an electrophysiologist might be beneficial.

Abstract
Bone sarcoma are infrequent diseases, representing < 0.2% of all adult neoplasms. A multidisciplinary management within reference centers for sarcoma, with discussion of the diagnostic and therapeutic strategies within an expert multidisciplinary tumour board, is essential for these patients, given its heterogeneity and low frequency. This approach leads to an improvement in patient's outcome, as demonstrated in several studies. The Sarcoma European Latin-American Network (SELNET), aims to improve clinical outcome in sarcoma care, with a special focus in Latin-American countries. These Clinical Practice Guidelines (CPG) have been developed and agreed by a multidisciplinary expert group (including medical and radiation oncologist, surgical oncologist, orthopaedic surgeons, radiologist, pathologist, molecular biologist and representatives of patients advocacy groups) of the SELNET consortium, and are conceived to provide the standard approach to diagnosis, treatment and follow-up of bone sarcoma patients in the Latin-American context.

Abstract
This study aimed to assess the prevalence of abuse against Portuguese older people after an economic crisis and to assess how it has influenced health. A cross-sectional study was carried out including 677 older adults (≥60 years) during 2017. Results show that overall, 23.9% of older people reported being a victim of abuse in the last 12 months. The prevalence of psychological abuse was 19.9%, financial abuse 5.8%, physical abuse 2.5% and sexual abuse 1.9%. Older people who report abuse were more likely to have perceived insufficient income and low social support. The abuse was also significantly associated with poor health status and depressive symptoms. Even in an auspicious period, more than a fifth of older people experiences abuse which is associated with social and health vulnerabilities. These results support that an investment should be made in terms of policies toward an age-friendly environment.

Abstract
Abstract
Background
CHA2DS2-VASc risk score is the main determinant for maintaining anticoagulation after atrial fibrillation (AF) ablation, irrespective of the procedure outcome. The presence of aortic plaques is included in the score, but isn't regularly assessed previously to AF ablation. This way, risk factors for coronary artery disease (CAD) other than arterial hypertension and diabetes mellitus may influence stroke risk in patients with AF, albeit not being included in the CHA2DS2-VASc score.
Purpose
We sought to evaluate the prevalence of aortic plaques diagnosed during transesophageal echocardiography (TOE) in patients submitted to AF ablation and to assess its determinants and clinical impact on the CHA2DS2-VASc score.
Methods
Retrospective study of patients submitted to AF ablation that performed TOE prior to the procedure, with assessment of aortic plaques. CHA2DS2-VASc risk score was evaluated in the pre-ablation patient evaluation and reassessed after TOE. Demographic, clinical and echocardiographic data, including cardiovascular risk factors, were analyzed. We assessed AF recurrence rate, cerebrovascular events and death during follow-up.
Results
120 patients were submitted to TOE prior to AF ablation from November 2015 to December 2020, mean age 66.6 (±9.55) years, 48% male. In 30 (25%) patients aortic plaques were identified in TOE. Mean CHA2DS2-VASc was 2.2 (±1.47) in pre-ablation evaluation and 2.5 (±1.69) post-TOE, increasing in all patients with aortic plaques and prompting beginning of oral anticoagulation in 5 patients. AF was paroxysmal in 74% and persistent in 26% of patients, mean duration of 6.28 (±3.76) years. Arterial hypertension was present in 79 (66%) of patients, type 2 diabetes mellitus in 24 (20%) and dyslipidemia in 67 (56%). 17 (14%) patients had a prior stroke. During a mean follow-up of 30 (±18.3) months, 32 (27%) patients had AF recurrence and 10 (8%) were submitted to redo procedures. 107 (89%) patients remained under oral anticoagulation, stroke occurred in 1 patient and 2 patients died.
In univariate analysis, age, type 2 diabetes mellitus and dyslipidemia predicted an increase in CHA2DS2-VASc score after TOE (respectively, OR 1.113, 95% CI 1.041–1.190, p-value 0.002; OR 2.907, 95% CI 1.145–7.379, p-value 0.025; and OR 2.442, 95% CI 1.016–5.868, p-value 0.046).
In multivariate analysis, age is the only independent predictor of increased CHA2DS2-VASc score after TOE (OR 1.095, 95% CI 1.013–1.185, p-value 0.023). No risk factor for CAD was independently associated with the presence of aortic plaques (Table 1).
Conclusion
In this population, single CAD risk factors were not independent predictors of aortic plaques. If TOE had not been performed prior to AF ablation, 25% of patients would have had an underestimated CHA2DS2-VASc score and would be off anticoagulation after the procedure, unprotected from thromboembolic events.

Abstract
Abstract
Background
The delay times of the patient and the system for primary percutaneous coronary intervention (p-PCI) have a determining impact on the prognosis of patients with acute myocardial infarction with ST segment elevation (STEMI).
Purpose
To identify the predictors of patient and system delay for p-PCI in the period of 2020 at a reference hospital for p-PCI.
Methods
Patients submitted to p-PCI in the period from March to September 2020 were included and compared with the same period in 2019. We analyzed the differences between the two groups regarding the patient's delay times, time from the onset of symptoms to the first medical contact (FCM) and the system (time from the first contact with the health system to p-ICP). Data collection of the patient's previous history, coronary intervention performed and post-PCI follow-up was performed using the electronic patient record. Univariate analysis and logistic regression models from multivariate analysis were used to determine the predictors of “patient delay” and “system delay” and adjusted for confounding factors. The analysis was performed with a significance level of 5%.
Results
We included in the study 255 patients who underwent p-PCI, of which 122 in the period from 2020 and 133 in the period from 2019. Regarding the characteristics of the population, there were no significant differences between the two periods. Regarding the patient's delay time, there were no statistically significant differences. The variable first medical contact with a non p-PCI center was the only variable associated with system delay>90 minutes in the multivariate analysis, OR (6.18: 95% CI, 1.91–20), p=0.002. There was a statistically significant association between the period of 2020 (pandemic period) and total ischemia time, but with a negative effect, dependent variable adjusted for confounding factors [adjusted OR: −0.10; 95% CI: −107.61 to −5.57; p=0.03].
Conclusion
In this study, the patient's admission to a non p-PCI centers was identified as the only predictor of longer delay until p-PCI (system delay). However, these results should serve as a contribution to decision making in order to mitigate risks, regardless of any associated catastrophe and eventually alert the population not to neglect the symptoms suspected of acute myocardial infarction.

Abstract
The study of dust intrusions in Portugal is still a subject on which little investigation has been made, especially in terms of their effects. Thus, this work aims to achieve two goals: firstly, to characterize the dust intrusions in the study area; and secondly, to evaluate the possible statistical association between the dust intrusion days and hospital admissions due to respiratory diseases. Dust intrusions in Portugal are prevalent during the summer season. During this season, the dust plumes tend to cover broader areas than in the other seasons and they have origin in the North African countries. In the study area for the period between 2005 and 2015, the relative risk of urgent hospitalizations due to respiratory diseases was 12.6% higher during dust intrusion days. In order to obtain this statistical association, a Distributed Lag Nonlinear Model was developed. With this work, we expect to help the development of further studies regarding North African dust intrusions in Portugal, more precisely their effects on human health.

Abstract
BACKGROUND Cancer patients configure a risk group for complications or death by COVID-19. For many of them, postponing or replacing their surgical treatments is not recommended. During this pandemic, surgeons must discuss the risks and benefits of treatment, and patients should sign a specific comprehensive Informed consent (IC). OBJECTIVES To report an IC and an algorithm developed for oncologic surgery during the COVID-19 outbreak. METHODS We developed an IC and a process flowchart containing a preoperative symptoms questionnaire and a PCR SARS-CoV-2 test and described all perioperative steps of this program. RESULTS Patients with negative questionnaires and tests go to surgery, those with positive ones must wait 21 days and undergo a second test before surgery is scheduled. The IC focused both on risks and benefits inherent each surgery and on the risks of perioperative SARS-CoV-2 infections or related complications. Also, the IC discusses the possibility of sudden replacement of medical staff member(s) due to the pandemic; the possibility of unexpected complications demanding emergency procedures that cannot be specifically discussed in advance is addressed. CONCLUSIONS During the pandemic, specific tools must be developed to ensure safe experiences for surgical patients and prevent them from having misunderstandings concerning their care.

Background
The greatest benefit with cardiac resynchronization therapy (CRT) is achieved when biventricular pacing (BivP) percentage (%) is close to 100%. However, in some patients that goal can be challenging to obtain.
Purpose
Determine whether a lower BivP% could lead to similar CRT response and events, as compared with patients with BivP% >98%.
Methods
Patients with CRT followed up in a remote-monitoring network were retrospectively analyzed. BivP% was assessed and response to CRT was defined as an absolute increase in left ventricle ejection fraction (LVEF) >5% or a relative increase in LVEF >15%.
Low BivP% was defined as <98%. Clinical, echocardiographic data and all-cause death during follow-up were evaluated. ROC curve and AUC were obtained to determine the discriminative power of BivP% as predictor of CRT response. Optimal cut-point value was obtained and patients were divided according to this value. Kaplan-Meyer survival function was used to compare survival in the different groups and the Log-rank test was used for comparison between the groups.
Results
88 patients, 76% male, median age 73.5 (IQR 65.75-79.25) years were included. A CRT-D was implanted in 69%. Etiology was ischemic in 44%. 93% were under beta-blockers. Median LVEF before CRT was 27% (IQR 20.25-32).
44 patients (50%) had low BivP% (median 91%, IQR 96-99), 55% due to atrial fibrillation and 52% due to frequent premature ventricular complexes. After optimization of medical therapy, device programming and/or interventional procedures, we obtained a BivP >98% in 26 out of the 44 patients (59%). However, in 18 patients (20%) BivP% was <98% (median 95, IQR 92.25-96). 66% patients were CRT responders. Median follow-up was 36 (IQR 23.75-84) months. During follow-up, all-cause mortality was 27% (24 patients).
Optimal cut-point value for predicting CRT response was 91% BivP% (AUC 0.644, p-value 0.047, 95% CI 0.496-0.792). The characteristics of the two groups didn’t differ significantly (Table).
Survival was significantly higher in patients with BivP% >91% (Log-rank 3.667, p-value 0.050) – Figure.
Conclusion
In this population, BivP% >91% was sufficient to achieve CRT-response and was associated with a better survival.

Background and aims
Activation wavefront is rapid and uniform in normal myocardium. Fibrosis is associated with deceleration zones (DZ) and late activated zones. The presence of low voltage areas (LVAs) in the right ventricular outflow tract (RVOT) of patients with premature ventricular contractions (PVCs) from this origin has been described previously. The aim of this study was to evaluate in sinus rhythm, the RVOT endocardial activation duration (EAD) and the presence of DZs, in patients with PVCs and in controls.
Methods
Consecutive patients with frequent (>10.000/24 h) idiopathic PVCs with inferior axis subjected to ablation that had an activation and voltage map of the RVOT performed in sinus rhythm. A control group of patients without PVCs that underwent ablation of supraventricular arrhythmias was also studied. Patients with structural heart disease, previous ablation or conduction disease were excluded. The RVOT EAD was measured as the time interval between the earliest and the latest activated region. Also evaluated the number of 10 ms isochrones throughout the RVOT and the maximal number of 10 ms isochrones within 1 cm, and a DZ was defined as a zone with > 3 isochrones within 1 cm. Low voltage areas (LVA) were defined as areas with local electrogram amplitude <1.5 mV.
Results
42 patients, 29 in the PVC group and 13 control subjects. The site of origin of the PVCs was the RVOT in 23 patients and the LVOT in 6. The characteristics of the two groups are displayed in the Table. Patients with PVCS had longer RVOT EAD, total number of isochrones and presence of DZ was also significantly higher (See table). LVAs were more frequent in PVCs from the RVOT than from the LVOT (83% vs 33%, p = 0.033). Patients with LVA had longer EAD 60 (52-67) vs 36 (34-40) ms, p < 0.0001 (Figure A) and more DZ than patients without LVA 95% vs 0%, p < 0.0001 (Figure B and C).
Conclusions
The velocity of the wavefront propagation was slower and DZs were more frequently present in patients with PVCs and were associated with presence of LVAs.

Abstract
Purpose: Incidence and mortality of prostate cancer (PCa) are still increasing in developing countries. Limited access to the health system or more aggressive disease are potential reasons for this. Ethnic and social differences in developed countries seem to make inappropriate to extrapolate data from other centers. We aim to report the epidemiological profile of a PSA-screened population from a cancer center in Brazil. Materials and Methods: We retrospectively selected 9.692 men enrolled in a PCa prevention program, comprising total PSA level and digital rectal examination at the first appointment, associated with complementary tests when necessary. Men aged over 40 years-old were included after shared decision-making process. Prostate biopsy (TRUS) was performed when clinically suspected for PCa. After the diagnosis, patients underwent appropriate treatment. Results: TRUS was performed in 5.5% of men and PCa incidence was 2.6%. Overall ratio between number of patients who needed to be screened in order to diagnose one cancer was 38.9 patients, with 2.1 biopsies performed to diagnose a cancer. Positive predictive value (PPV) of TRUS biopsy in this strategy was 47.2%, varying from 38.5% (<50 years-old) to 60% (>80 years-old). We evidenced 70 patients (27.9%) classified as low risk tumors, 74 (29.5%) as intermediate risk, and 107 (42.6%) as high-risk disease. Conclusions: PSA-screening remains controversial in literature. In front of a huge miscegenated people and considering the big proportion of high-risk PCa, even in young men diagnosed with the disease, it is imperative to inform patients and health providers about these data particularities in Brazil.

Abstract
IntroductionInsight is a complex and multidimensional phenomenon. Metacognition, awareness of illness or anosognosia are some of the terms used to designate this feature of the mental state exam.ObjectivesTo attempt to explore the evolution of the concept of insight as a psychiatric symptom over the years and to bring up some up-to-date features on this theme.MethodsLiterature review, using the most relevant papers, with the keywords “psychiatric insight”, “awareness of illness”, “metacognition” and “phenomenology”.ResultsThe term ‘insight’ has been described since 1896 when Kraepelin had noticed that patients with dementia praecox were unaware of their condition. Nowadays, it is recognized in several psychiatric disorders, with different meanings in each one. Overall, insight in psychiatry involves an attempt to see one’s thinking and behaviour ‘objectively’ and comparing it to some representation of mental health. Impaired insight has been linked to poor treatment compliance and outcomes, overall symptom severity, higher relapse, lower self-esteem, and impaired psychosocial functioning. White matter and connectivity problems may be related to poorer insight, as well as impaired frontal lobe functioning. In psychotic disorders, lack of insight is a primary symptom with poorer outcomes. Regarding affective disorders, the lower the mood the better the insight. Neuroimaging has been correlating insight with the inferior frontal gyrus, anterior insula, inferior parietal lobule, and ventromedial prefrontal cortex. In everyday practice, there are scales used to assess insight.ConclusionsInferences about patients’ insight are important to evaluate severity of illness, suicidal risk, compliance, and response to treatment.

Abstract
Introduction Nowadays, ‘Acute and transient psychotic disorders’ in ICD-10 and ‘Brief psychotic disorders’ in DSM-5 are both classifications of the same clinical entity. Over the years, several concepts have been formulated to define the same syndrome. Objectives To explore the historical evolution of brief psychotic disorders and relate them to current nosologies. Methods Literature review, using the most relevant papers, with the keywords “brief psychosis”, “bouffée délirante”, “cycloid psychosis”, “psychogenic psychosis”, “atypical psychosis” and “holodysphrenia”. Results Initially, in 1896, Kahlbaum coined the term ‘dysphrenia’, a group of severe form of psychosis that remitted without showing the typical sequence of disease states and without leaving a lasting alteration. Later, Kraepelin included this kind of disorder in manic depressive illness, which he first named as ‘periodic delirium’ and then as ‘delirious mania’. Magnan, in the pre-Kraepelinian era, created the term ‘bouffée délirante’, a sudden onset of delusional ideas with rapid evolution and intense symptomatology with complete remission usually followed after a short time. Later on, Henry Ey grabbed this entity and renewed it, contrasting it to the defined concept of schizophrenia. Other psychiatric schools have proposed numerous designations: ‘cycloid psychosis’ by Kleist from the German school, ‘psychogenic psychosis’ by Wimmer of the Scandinavian school and ‘holodysphrenias’ by Barahona-Fernandes from the Portuguese school. Cultural variants are also observed, as ‘amok’ seen in Malaysia or ‘shinbyung’ in Korea. Conclusions The intensity and polymorphism of brief psychosis present a clinical challenge. The historical evolution may be helpful on recognizing this entity in current clinical practice.

Abstract
BACKGROUND AND PURPOSE Optimal treatment of extremity soft tissue sarcomas (ESTS) is controversial. The aim of this study was to evaluate neoadjuvant chemotherapy (ChT) plus concomitant hypofractionated RT (hypo-RT) in local and distant disease relapse. Here we report safety, feasibility and early outcomes. MATERIALS AND METHODS This was a prospective, single arm study with a goal accrual of 70 patients. Between 2015 and 2018, 18 patients with histologically confirmed nonmetastatic ESTS were assigned to receive doxorubicin and ifosfamide for three neoadjuvant cycles, concomitant with hypo-RT (25 Gy in 5 fractions) followed by surgery. The primary endpoint was disease-free survival (DFS). Secondary outcomes were pathologic response, wound complications (WC), and morbidity rates. RESULTS Median follow-up was 29 months. At last follow-up, 13/18 patients were alive without evidence of local or systemic disease (DFS 72%), 1 had died due to metastatic disease, and 3 were alive with distant metastasis. One patient presented with local relapse within the irradiated field. Mean DFS time was 48.6 months (95% CI: 37.3-59.9). Six patients (33%) had no residual viable tumor detected in pathologic specimens (3 of these myxoid liposarcomas). There was a significant difference in WC among patients with acute RT skin toxicity. Six patients (33%) developed major WC. No grade 3 or 4 ChT adverse events were reported. CONCLUSION Despite the limited sample size, these early outcomes demonstrate that this treatment regimen is feasible and well tolerated with high rates of limb preservation, local control, and pathologic complete response, supporting further investigation in a multi-institutional setting.

Abstract
Summary Introduction. Severe systemic reactions (SR) to allergen subcutaneous immunotherapy (SCIT) are rare but local reactions (LR) are common. We aimed to characterize the type of reactions and safety profile. Methods. Retrospective analysis of medical record from patients under SCIT between 2013-2016. Results. Total of 7372 SCIT injections in 323 patients: 52% female; mean age 30 years (SD 13); mean treatment time 19 months (SD 13). There were 57 patients (17.6% of population, 70% female) with at least one adverse reaction, for 93 reactions described (1.3% injections). There were 79 LR (1.1% injections) in 46(14.2%) patients: 36 in build-up, 43 in maintenance. There were 14 SR (0.19% injections) in 12(3.7%) patients: 12 in build-up, 2 in maintenance. All SR were grade 1. The majority of reactions were caused by mite SCIT (69.9%). Conclusions. SCIT is safe and well tolerated, with no report of SR grade > 1.

Abstract
Simple Summary Desmoplastic small round cell tumor is a rare neoplasm with extremely aggressive behavior. Despite the multimodal treatment for newly diagnosed patients with chemotherapy, cytoreductive surgery and radiation, the cure rate is still low. For relapsed or progressive disease, there is limited data regarding second and third-line therapies. Novel agents have shown only modest activity. Recent molecular changes have been identified in this disease and this opens opportunities to be explored in future clinical trials. Abstract Desmoplastic small round cell tumor (DSRCT) is an extremely rare, aggressive sarcoma affecting adolescents and young adults with male predominance. Generally, it originates from the serosal surface of the abdominal cavity. The hallmark characteristic of DSRCT is the EWSR1–WT1 gene fusion. This translocation up-regulates the expression of PDGFRα, VEGF and other proteins related to tumor and vascular cell proliferation. Current management of DSRCT includes a combination of chemotherapy, radiation and aggressive cytoreductive surgery plus intra-peritoneal hyperthermic chemotherapy (HIPEC). Despite advances in multimodal therapy, outcomes remain poor since the majority of patients present disease recurrence and die within three years. The dismal survival makes DSRCT an orphan disease with an urgent need for new drugs. The treatment of advanced and recurrent disease with tyrosine kinase inhibitors, such as pazopanib, sunitinib, and mTOR inhibitors was evaluated by small trials. Recent studies using comprehensive molecular profiling of DSRCT identified potential therapeutic targets. In this review, we aim to describe the current studies conducted to better understand DSRCT biology and to explore the new therapeutic strategies under investigation in preclinical models and in early phase clinical trials.

Abstract
Prostate cancer (PCa) treatment has been greatly impacted by the robotic surgery. The economics literature about PCa is scarce. We aim to carry-out cost-effectiveness and cost-utility analyses of the robotic-assisted radical prostatectomy (RALP) using the "time-driven activity-based cost" methodology. Patients who underwent radical prostatectomy in 2013 were retrospectively analyzed in a cancer center over a 5-year period. Fifty-six patients underwent RALP and 149 patients underwent retropubic radical prostatectomy (RRP). The amounts were subject to a 5% discount as correction of monetary value considering time elapsed. Calculation of the Incremental Cost-Effectiveness Ratios (ICER) related to events avoided and the Incremental Cost-Utility Ratio (ICUR) related to "QALY saved" were performed. QALY was performed using values of utility and "disutility" weights from the "Cost-Effectiveness Analysis Registry". Hypothetical cohorts were simulated with 1000 patients in each group, based on the treatment outcomes. Total and average costs were R$1,903,671.93, and R$12,776.32 for the RRP group, and R$1,373,987.26, and R$24,535.49 for the RALP group, respectively. The costs to treat the hypothetical cohorts were R$10,010,582.35 for RRP, and R$19,224,195.90 for RALP. ICER calculation evidenced R$9,213,613.55 of difference between groups. ICUR was R$ 22,690.83 per QALY saved. Limitations were the lack of cost-effectiveness analyses related to re-hospitalization rates and complications, single center perspective, and currency-translation differences. Medical fees were not included. RALP showed advantages in cost-effectiveness and cost-utility over RRP in the long term. Despite the increased costs to the introduction of robotic technology, its adoption should be encouraged due to the gains.

Abstract
BACKGROUND Concurrent chemoradiation is standard-of-care for patients with squamous cell carcinoma of the anus. Poor compliance to chemotherapy, radiotherapy treatment interruptions and unplanned breaks may impact adversely on long-term outcomes. METHODS The ACT II trial recruited 940 patients with localised squamous cell carcinoma of the anus, and assigned patients to mitomycin (week 1) or cisplatin (weeks 1 and 5), with fluorouracil (weeks 1 and 5) and radiotherapy (50.4 Gy in 28 fractions over 38 days). This post hoc analysis examined the association between baseline factors (age, gender, site, T stage and N stage), and compliance to treatment (radiotherapy and chemotherapy), and their effects on locoregional failure-free survival, progression-free survival (PFS) and overall survival (OS). Compliance was categorised into groups. Radiotherapy: six groups according to total dose and overall treatment time (OTT). Chemotherapy: three groups (A = per-protocol; B = dose reduction or delay; C = omitted). RESULTS A total of 931/940 patients were assessable for radiotherapy and 936 for chemotherapy compliance. Baseline glomerular filtration rate <60 ml/min and cisplatin were significantly associated with poor week 5 compliance to chemotherapy (P = 0.003 and 0.02, respectively). Omission of week 5 chemotherapy was associated with significantly worse locoregional failure-free survival [hazard ratio (HR) 2.53 (1.33-4.82) P = 0.005]. Dose reductions/delays or omission of week 5 chemotherapy were associated with significantly worse PFS {HR: 1.56 [95% confidence interval (CI): 1.18-2.06], P = 0.002 and HR: 2.39 (95% CI: 1.44-3.98), P = 0.001, respectively} and OS [HR: 1.92 (95% CI: 1.41-2.63), P < 0.001 and HR: 2.88 (95% CI: 1.63-5.08), P < 0.001, respectively]. Receiving the target radiotherapy dose in >42 days is associated with worse PFS and OS [HR: 1.72 (95% CI: 1.17-2.54), P =0.006]. CONCLUSION Poor compliance to chemotherapy and radiotherapy were associated with worse locoregional failure-free survival, PFS and OS. Treatment interruptions should be minimised, and OTT and total dose maintained. CLINICAL TRIAL NUMBER ISRCTN 26715889.

Abstract
The consumption of psychoactive substances is considered a growing problem in many communities. Moreover, new psychoactive substances (NPS) designed as (legal) substitutes to traditional illicit drugs are relatively easily available to the public through e-commerce and retail shops, but there is little knowledge regarding the extent and actual use of these substances. This study aims to gain new and complementary information on NPS and traditional illicit drug use at six music festivals across Europe by investigating wastewater and pooled urine. Samples were collected, between 2015 and 2018, at six music festivals across Europe with approximately 465.000 attendees. Wastewater samples were also collected during a period not coinciding with festivals. A wide-scope screening for 197 NPS, six illicit drugs and known metabolites was applied using different chromatography-mass spectrometric strategies. Several illicit drugs and in total 21 different NPS, mainly synthetic cathinones, phenethylamines and tryptamines, were identified in the samples. Ketamine and the traditional illicit drugs, such as amphetamine-type stimulants, cannabis and cocaine were most abundant and/or frequently detected in the samples collected, suggesting a higher use compared to NPS. The analyses of urine and wastewater is quick and a high number of attendees may be monitored anonymously by analysing only a few samples which allows identifying the local profiles of use of different drugs within a wide panel of psychoactive substances. This approach contributes to the development of an efficient surveillance system which can provide timely insight in the trends of NPS and illicit drugs use.
