Abstract
OBJECTIVES The aim of this study was to map and compare stakeholders' perceptions of barriers towards cervical cancer screening for vulnerable women in seven European countries. DESIGN In Collaborative User Boards, stakeholders were invited to participate to identify barriers towards participation in cervical cancer screening. SETTING The study is nested in the European Union-funded project CBIG-SCREEN which aims to tackle inequity in cervical cancer screening for vulnerable women (www.cbig-screen.eu). Data collection took place in Bulgaria, Denmark, Estonia, France, Italy, Portugal and Romania. PARTICIPANTS Participants represented micro-level stakeholders covering representatives of users, that is, vulnerable women, meso-level stakeholders covering healthcare professionals and social workers, and macro-level stakeholders covering programme managers and decision-makers. METHODS Across the seven countries, 25 meetings in Collaborative User Boards with a duration of 2 hours took place between October 2021 and June 2022. The meetings were video recorded or audio recorded, transcribed and translated into English for a qualitative framework analysis. RESULTS 120 participants took part in the Collaborative User Boards. Context-specific barriers were related to different healthcare systems and characteristics of vulnerable populations. In Romania and Bulgaria, the lack of a continuous screening effort and lack of ways to identify eligible women were identified as barriers for all women rather than being specific for women in vulnerable situations. The participants in Denmark, Estonia, France, Italy and Portugal identified providers' lack of cultural and social sensitivity towards vulnerable women as barriers. In all countries, vulnerable women's fear, shame and lack of priority to preventive healthcare were identified as psychological barriers. CONCLUSION The study provides an overview of stakeholders' perceived barriers towards vulnerable women's cervical cancer screening participation in seven European countries. The organisation of healthcare systems and the maturity of screening programmes differ between countries, while vulnerable women's psychological barriers had several similarities.

Abstract
Edible flowers are regaining interest among both the scientific community and the general population, not only for their appealing sensorial characteristics but also from the growing evidence about their health benefits. Among edible flowers, those that contain anthocyanins are among the most consumed worldwide. However, little is known regarding the bioaccessibility and absorption of their bioactive compounds upon ingestion. The aim of this work was to explore, for the first time, the behavior of anthocyanin-rich extracts from selected edible flowers under different food processing conditions and after ingestion using simulated digestions, as well as their absorption at the intestinal level. Overall, the results showed that the monoglucoside and rutinoside anthocyanin extracts were less stable under different pH, temperature, and time conditions as well as different digestive processes in the gastrointestinal tract. There was a prominent decrease in the free anthocyanin content after the intestinal phase, which was more pronounced for the rutinoside anthocyanin extract (78.41% decrease from the oral phase). In contrast, diglucoside and rutinoside anthocyanin extracts showed the highest absorption efficiencies at the intestinal level, of approximately 5% after 4 h of experiment. Altogether, the current results emphasize the influence of anthocyanins' structural arrangement on both their chemical stability as well as their intestinal absorption. These results bring the first insights about the bioaccessibility and absorption of anthocyanins from wild pansy, cosmos, and cornflower and the potential outcomes of such alternative food sources.

Abstract
Introduction Cancer patients on active treatment are at increased risk of developing coronavirus disease 2019 (COVID-19), making effective immunization of the utmost importance. However, the effectiveness of vaccination in this population is still unclear. This study aims to evaluate the response against COVID-19 in a cohort of patients with active cancer under immunosuppressive therapy. Methods This was a prospective, cross-sectional, single-center study that included patients with cancer under immunosuppressive therapy vaccinated against COVID-19 between April and September 2021. Exclusion criteria were: previous known severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, single-dose vaccine or incomplete vaccination scheme. Immunoglobulin G (IgG) anti-SARS-CoV-2 antibody levels were assessed using 35.2 binding antibody units (BAU)/mL as the positive cut-off. Assessments were performed 14-31 days after the first and second dose and three months after the second dose. Results A total of 103 patients were included. The median age was 60 years. Most patients were being treated for gastrointestinal cancer (n=38, 36.9%), breast cancer (n=33, 32%) or head and neck cancer (n=18, 17.5%). At evaluation, 72 patients (69.9%) were being treated with palliative intent. The majority were being treated with chemotherapy (CT) alone (57.3%). At the first assessment, levels of circulating SARS-CoV-2 IgG consistent with seroconversion were present in 49 patients (47.6%). At the time of the second assessment, 91% (n=100) achieved seroconversion. Three months after the second dose, 83% (n=70) maintained levels of circulating SARS-CoV-2 IgG consistent with seroconversion. In this study, no SARS-CoV-2 infection was reported in the study population. Conclusions Our findings suggest that this group of patients had a satisfactory COVID-19 immunization response. Although promising, this study should be replicated on a wider scale in order to validate these findings.

Abstract
In late November 2020, when Europe reached the highest 14-day incidence of COVID-19 cases, the resource-intensive and time-consuming traditional contact tracing performed by Public Health was challenged. In this context, innovative approaches were necessary to guarantee a timely interruption of disease transmission. “COVID-19 Collaborative Screening” Project was developed as a faster solution, not only because the contact tracing process is simpler for the operator, but mainly because it is possible to quickly scale up the number of operators involved. It was designed to interrupt family and social transmission chains, in a partnership with the Local Public Health Services – allowing these services to dedicate to scenarios of more complex risk assessment, using the traditional contact tracing. To perform contact tracing, this method involves Public Servants, Armed Forces and Medical Dentists. The Project also promotes participatory citizenship, by delegating to the citizen the responsibility of registering his/hers contacts with high-risk exposure in an online form, in contrast to the traditional contact tracing method which is more health professional-dependent. Until the end of January 2021, the Project has trained eight teams, enrolling a total of 213 professionals, and was implemented in eight Health Regions (with an estimated population of 1,346,150 inhabitants). The Project was successful at facing the delays in case interview and contact tracing. The strategy implemented by ColabCOVID is assembled as a sustainable, reproducible and scalable platform and is ready to be re-implemented to face the emergence of more contagious variants, as well as an eventual forthcoming health threat.

Abstract
Abstract
Introduction
Severe aortic stenosis (AS) and mitral regurgitation (MR) often coexist. Transcatheter aortic valve implantation (TAVI) is becoming widely used for the treatment of patients (pts) with symptomatic severe AS. However, conflicting data reside concerning the impact of MR on outcomes after TAVI. Also, very few data exist regarding the benefits of a cardiac rehabilitation program (CRP) following TAVI in pts with MR.
Purpose
To evaluate the effect of a CRP in functional parameters after TAVI, particularly in pts with MR grade ≥ II.
Methods
Retrospective study which included all pts submitted to TAVI between 2014 and 2020 that completed a CRP following the procedure. Cardiopulmonary exercise tests (CPET) were performed after TAVI at baseline (pre-CRP) and post-CRP. We evaluated pre- and post-CRP peak oxygen consumption (pVO2), pVO2 at the anaerobic threshold (AT), respiratory exchange ratio (RER), VE/VCO2 and CPET duration. The exercise protocol included low/medium intensity exercises and consisted of sessions 3 times per week carried over 3 months. MR grading severity was assessed with transthoracic echocardiography performed after TAVI and was divided into 2 groups (grade < II vs grade ≥ II).
Results
Fifty-two pts were included, 59,6% were male, mean age of 78,6±8,6 years-old. Mean Society of Thoracic Surgery (STS) risk score was 4,9. Mean pre-TAVI aortic valve area was 0,68 cm2, with a mean gradient of 45,5 mmHg and a mean ejection fraction (EF) of 51%. The majority of pts implanted a self-expandable prosthesis (55,8%).
Twenty-seven (51,9%) pts had MR grade ≥ II. Baseline characteristics were similar between pts with MR grade < II vs MR grade ≥ II, with the exception of the prevalence of coronary artery disease which was higher in MR grade ≥ II (p=0,036). Patients with MR grade < II had higher maximum and median aortic gradients before TAVI (p<0,05 for all). The mean number of cardiac rehabilitation sessions was 21±7, without differences between both groups. In pts with MR grade ≥ II, there was an improvement in CPET duration after CRP (HF protocol from 03:57 min to 05:02 min; p=0,017 and modified Bruce protocol from 06:03 min to 06:41 min; p=0,049) but without significant changes in pVO2 (14,7 mL/kg/min to 14,9 mL/kg/min; p=0,990), RER or VEVCO2/VO2 ratio. Patients with MR grade < II significantly improved pVO2 (13,8 mL/kg/min to 14,7 mL/kg/min; p=0,015), and CPET duration with HF protocol from 05:04 min to 06:23 min; p=0,006 after CRP. There was also an improvement in VEVCO2/VO2 ratio, although not statically significant.
Conclusions
Patients with MR grade < II after TAVI who underwent a CRP significantly improved pVO2 and CPET duration. Although pts with MR grade ≥ II did not improved pVO2 after a CRP, an improvement in CPET duration may translate into a clinical benefit in these pts. These results highlight the importance of further research and personalization among this potentially higher risk subset of pts.

Abstract
Abstract
Introduction
Resistant hypertension is a major challenge of modern cardiovascular medicine, as it is a puzzling problem without a clear solution. Exercise training clearly reduces blood pressure (BP) and oxidative stress in patients with hypertension, however evidence is limited regarding resistant hypertension.
Purpose
To determine the effect of an aerobic exercise training program in BP, angiotensin II and oxidative stress in patients with resistant hypertension.
Methods
EnRicH is a prospective, two-center, single-blinded, randomized controlled trial with a parallel two-arm group. Sixty patients with resistant hypertension were randomly assigned in a 1:1 ratio to undergo a 12-week aerobic exercise training program (exercise) or usual care (control). The powered primary efficacy measure was 24-hour ambulatory systolic BP change from baseline. Secondary outcome measures included daytime and nighttime ambulatory BP, office BP, cardiorespiratory fitness, and oxidative stress and inflammatory biomarkers: Interferon-gamma (IFN-y), Angiotensin II, vascular endothelial growth factor (VEGF), and superoxide dismutase (SOD).
Results
Fifty-three patients (exercise n=26, control n=27) completed the study. Patients were mainly women (54.7%), with an office BP of 140.7±15.9/84.2±9.4 mm Hg and taking an average of 4.6 antihypertensive medications (median, 5; range, 3 to 7). At baseline, no differences were found between groups for the study outcomes and patient characteristics. Ambulatory systolic BP was reduced −7.1 mm Hg (95% CI, −12.8 to −1.4; P=0.015) in the exercise group (127.4±12.2 to 121.2±12.2, p=0.007) compared to control group (126.1±17.2 to 126.9±15.2, p=514) over 24-hour. In addition, 24-hour ambulatory diastolic BP (−5.1 mm Hg, −7.9 to −2.3, P=0.001), daytime ambulatory systolic (−8.4 mm Hg, −14.3 to −2.5, P=0.006), and diastolic BP (−5.7 mm Hg, −9.0 to −2.4, P=0.001) were also reduced in the exercise group compared to the control group. There were no differences in the change of nighttime ambulatory BP between groups. Cardiorespiratory fitness improved in the exercise group by 14% (4.7 ml.kg-1.min-1, P<0.001), while it remained unchanged in the control group (−0.37 ml.kg-1.min-1, P=0.442). A significant between-group difference in favor of exercise group was found for IFN-y (−4.3 pg/mL, 95% CI: −7.1 to −1.5; P=0.003), Angiotensin II (−157.0 pg/mL, 95% CI: −288.1 to −25.9; P=0.020), VEGF (10.53 pg/mL, 95% CI: 0.60 to 22.54; P=0.035), and SOD (0.35 pg/mL, 95% CI: 0.10 to 0.58; P=0.009).
Conclusions
A 12-week moderate intensity aerobic exercise program reduced ambulatory BP, angiotensin II and oxidative stress in patients with resistant hypertension. The antihypertensive effects of exercise in patients with resistant hypertension may be mediated by positive changes in oxidative stress and inflammatory biomarkers.

Abstract
Abstract
Background
The objective of this study was to verify wether it was possible to observe greater plasticity of the auditory cortex and greater benefits in terms of auditory processing, better discrimination, attention and identification of rare stimuli, in musicians, verified through the performance of Long Latency Auditory Evoked Potential, P300, with and without competitive noise, in musicians compared to non-musician.
Methods
20 individuals were divided into two groups: 8 in the musicians, and 12 in the control group. The P300 values were compared between the two groups and then between the results of the P300 with and without competitive noise, in both groups.
Results
When comparing the results without competitive noise, it appears that the average amplitude was higher in the group of musicians compared to the control group, in both ears. Latency was lower in the control group, only in the right ear. With competitive noise, in both groups, the average amplitude is lower, compared to the results of the P300 without competitive noise, both in the right ear and in the left ear, and this effect is more considerable in the group of musicians. Regarding latency, theaverage of the P300 with competitive noise, in both ears, with a greater increase in latency values, in the group of musicians.
Conclusion
Musicians show a greater cortical inhibition effect compared to non-musicians, demonstrating that the musician’s central auditory system shows greater activation, which can result in better performance in functions such as attention and discrimination, due to training by musical practice.

Introduction
Amyloid-like protein aggregates play a decisive role in the pathology of heart failure. Alterations in protein homeostasis, in particular, the clearance of toxic amyloid-like aggregates are emerging therapeutic targets in cardiovascular medicine. The clinical benefits of cardiac rehabilitation and exercise training are widely accepted in heart failure; however, little is known about the potential benefit of exercise training in amyloid-like protein aggregates.
Purpose
To assess the effects of a moderate-intensity exercise training program on amyloid-like protein aggregates levels among patients with heart failure with reduced ejection fraction.
Methods
Eighteen subjects participated in the study; eight patients (age: 66.6 ± 5.9 years; FEVE: 38.4 ± 8.9%) with heart failure with reduced ejection fraction participated in a 3-month exercise training program (2 x 60 min sessions per week of moderate-intensity aerobic and resistance exercise). Ten healthy subjects (age: 68. 4 ± 3.1 years) were recruited to an age-matched reference group. Amyloid-like protein aggregates were assessed before and after 3 months of exercise training. Clinical data, medication, anthropometrics, and cardiorespiratory fitness were also assessed. Thioflavin T (ThT) dye fluorescence was used to quantify the plasma levels of amyloid-like aggregates and the Fourier transform infrared spectroscopy (FTIR) was applied to evaluate the conformation of cross-β-sheet structures characteristic of amyloid protein aggregates.
Results
Exercise program improved cardiorespiratory fitness by 14.0 ± 17.1% (17.4 ± 3.2 to 19.7 ± 2.9 ml/kg/min) and reduced NT-proBNP levels by 16.5% (34.2) (median concentration of 632 pg/mL (720.8) to 517.5 pg/mL (707.0)) in the heart failure patients. A slight decrease of amyloid-like aggregates levels was observed in post-exercise training samples (a reduction of 3.1%); interestingly, after the exercise training program, the heart failure patients showed levels of amyloid-like aggregates similar to the reference group (1132.0 ± 114.2 vs. 1094.8 ± 132.9 a.u.). Additionally, the PLS-R multivariate analysis of the amide I region of the FTIR spectra revealed enrichment of antiparallel β-sheets (1693 cm-1) assigned to amyloid-like oligomers in the samples of heart failure patients before, but not after, the exercise program. Of note, oligomeric species, as intermediates of amyloid assembly, can contribute to the increase of amyloid burden, but also, some have been reported to be highly reactive and toxic to cells, being key elements of amyloid pathogenesis.
Conclusions
Our preliminary results indicate that 3 months of exercise training may have significant effects on amyloid-like oligomers, and start hindering the formation of the larger ThT-positive aggregates among patients with heart failure.

Abstract
BACKGROUND In patients with recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) the estimated prognosis is usually poor. Patient-specific factors that affect prognosis should be considered when choosing therapy. We conducted a retrospective, single-center analysis in patients treated with first line platinum and antiEGFR antibody-containing regimen. The objective was to generate real-world data considering treatment outcomes and to identify predictors of survival. PATIENTS/METHODS Clinical charts of patients treated with cetuximab and platinum-based chemotherapy (CT) for R/M HNSCC in first-line setting, between January-2009 and December-2018 were assessed. In these 103 patients, the prognostic value of site of the primary tumor, age at diagnosis, gender, Cetuximab induced skin toxicity and prior treatments were studied multivariately. To evaluate progression free survival (PFS) and overall survival (OS), Kaplan-Meier curves and the log-rank test were used. The Coxregression model was used to investigate the effect of these variables on OS. RESULTS Longer OS was associated with oral cavity tumor location (p = 0,003), European Cooperative Oncology Group-Performance Status 0 (ECOG-PS) (p = 0,01), complete/partial response (p<0,0001), cetuximab monotherapy until disease progression or unacceptable toxicity (p = 0,037) and Grade 2-4 cetuximab induced skin toxicity (p = 0,037). The median follow-up period was 11,7 months. The mortality rate was 90,3% during this retrospective cohort assessment. The PFS was 7,1 months (95% confidence interval (CI), 5,6-8.6). The OS was 11,7 months (95%CI, 10,5-12,8). CONCLUSIONS The present study demonstrates that the combination of cetuximab with platinum-based CT was effective in R/M HNSCC. Among patients with R/M HSCC treated with platinum plus cetuximab as first-line therapy, primary site, ECOG-PS, grade 2-4 cetuximab induced toxicity, and weekly cetuximab monotherapy have a marked impact on OS.

Abstract
An adrenal oncocytic neoplasm is an extremely rare tumour arising from the adrenal gland and it should be considered in the differential diagnosis of an adrenal incidentaloma, since it is frequently non-functioning. The suspicion for malignancy is high when an adrenal incidentaloma is >4 cm in size; however, adrenal oncocytomas are large, measuring an average of 8 cm, are round and encapsulated, and normally have a benign behaviour. We present a case of a 55-year-old male patient with dyslipidaemia, medicated with simvastatin. Upon complaints of abdominal pain, the general physician asked for an abdominal ultrasound that revealed an adrenal lesion, further characterized with a computed tomography scan, which showed an adrenal lesion measuring 49 × 64 × 56 mm and a calcification focus. The patient was referred to the general surgery and endocrinology department. The analytical study was negative for pheochromocytoma or Cushing's syndrome, which allowed surgery to be conducted, as is recommended. The aim of this case report is to contribute to the knowledge on adrenal oncocytomas, since there is scarce information based on singular experiences.

Abstract
INTRODUCTION Infective endocarditis (IE) is a serious disease with significant in-hospital mortality (15-30%) despite advances in medical and surgical therapy. AIMS To perform a clinical characterization of patients undergoing cardiac surgery for IE and to identify factors that predict in-hospital mortality. METHODS We retrospectively analyzed 145 patients with IE admitted between January 2006 and October 2017. RESULTS The median age was 72 years. IE was acquired mainly in the community (69%), and involved the native aortic valve in 54% of patients, biological prosthetic valves in 22.1% and mechanical valves in 10.3%. Staphylococcus spp. (31.0%) were the most frequent etiological agents. Cardiac surgery was emergent in 29 patients, urgent in 108, and elective in eight. The main indications were heart failure (57.9%), large vegetations (20%), systemic embolism (17.2%) and valve dysfunction (15.2%). Overall, biological valves were implanted in 62.1% of patients and mechanical valves in 37.2%. A total of 19 patients (13.1%) died. Predictors of mortality were preoperative atrial fibrillation and lower left ventricular ejection fraction, postoperative severe valve regurgitation associated with cardiogenic shock, sepsis, septic shock associated with cardiogenic shock, cardiac tamponade, need for renal replacement therapy and, although without statistical significance, emergent surgery. CONCLUSIONS There is a need for better indicators to enable early identification of surgical candidates for IE, implementation of a heart team, and better surgical strategies, including more rapid intervention, more specific postoperative care, and optimal antibiotic therapy.

Abstract
This study aimed to evaluate the psychosocial differences between patients with psoriasis in different phases of the disease. Seventy-one patients in exacerbation and 83 in remission were evaluated regarding sociodemographic, clinical and psychological variables, on the premise that the visibility of lesions (exacerbation phase) may impact the emotional regulation and embitterment. A regression analysis was performed to identify the variables that contribute to explain embitterment: a diagnosis of anxiety and/or depression and psoriasis severity are the identified ones. The results point to higher values of emotional dysregulation and embitterment, as well as more critical clinical variables in patients with active disease, namely, alcohol and coffee consumption, smoking and less satisfaction with current treatment, more diagnoses and more family history of anxiety and depression, more psychology/psychiatry consultations and more use of anxiolytics and antidepressants. However, only the results referring to alcohol consumption and embitterment are significantly higher in subjects in the exacerbation phase of the disease. Particular clinical attention should be provided to patients in exacerbation phase regarding psychotherapeutic approach.

Abstract
Several case reports have been published describing the coexistence of sarcoidosis and cancer. In the literature, simultaneous occurrence of head and neck cancer and sarcoidosis is rarely reported. In this paper we present a case of a 42-year-old man with squamous cell carcinoma of the oral cavity, locally advanced, which after surgery and adjuvant radiotherapy developed local persistence and progression in the mediastinal lymph nodes. The patient was submitted to chemotherapy and after a complete response, new suspicious mediastinal and hilar lymph nodes appeared in the thoracic computed tomography (CT) scan and 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) scan. To enroll the patient in a clinical trial, the patient underwent mediastinoscopy with mediastinal lymph node dissection. The histopathological findings were consistent with sarcoidosis and no metastatic disease was found. Since the patient had no symptoms and the levels of serum angiotensin converting enzyme were normal, no further pharmacological intervention was done. After 4 years of follow up the patient remains without evidence of cancer. This case shows that although imagological techniques (CT and FDG-PET scan) are extensively used to assess the tumor response, false-positive cases can occur. Whenever it is possible a biopsy of the suspected metastatic site should always be performed.

Abstract
The two SIBLING (Small Integrin Binding Ligand N-linked Glycoproteins), bone sialoprotein (BSP) and osteopontin (OPN) are expressed in osteoblasts and osteoclasts. In mature BSP knockout (KO, -/-) mice, both bone formation and resorption as well as mineralization are impaired. OPN-/- mice display impaired resorption, and OPN is described as an inhibitor of mineralization. However, OPN is overexpressed in BSP-/- mice, complicating the understanding of their phenotype. We have generated and characterized mice with a double KO (DKO) of OPN and BSP, to try and unravel their respective contributions. Despite the absence of OPN, DKO bones are still hypomineralized. The SIBLING, matrix extracellular phosphoglycoprotein with ASARM motif (MEPE) is highly overexpressed in both BSP-/- and DKO and may impair mineralization through liberation of its ASARM (Acidic Serine-Aspartate Rich MEPE associated) peptides. DKO mice also display evidence of active formation of trabecular, secondary bone as well as primary bone in the marrow-ablation repair model. A higher number of osteoclasts form in DKO marrow cultures, with higher resorption activity, and DKO long bones display a localized and conspicuous cortical macroporosity. High bone formation and resorption parameters, and high cortical porosity in DKO mice suggest an active bone modeling/remodeling, in the absence of two key regulators of bone cell performance. This first double KO of SIBLING proteins thus results in a singular, non-trivial phenotype leading to reconsider the interpretation of each single KO, concerning in particular matrix mineralization and the regulation of bone cell activity.

Abstract
Different types of topical preparations are available as anti-psoriatic medicines, semisolid formulations being the preferred dosage forms for the treatment of body lesions. The mechanical characterization of these semisolid formulations is seldom reported, although mechanical features have been recognized to play an important role in treatment acceptability and adherence. The aim of this study was to characterize the mechanical properties of semisolid topical formulations commercially available for psoriasis treatment. One complementary aim was to evaluate patient satisfaction with topical treatment and discuss the results according to the mechanical features of the dosage form. Eight ointments (O 1-8), five creams (C 1-5), one oleogel (G1), and one excipient (E1-petrolatum) were characterized for textural properties (spreadability and penetration tests) and flow behavior. Power law model was fitted to the results. A questionnaire for the assessment of satisfaction with topical medicines used for psoriasis treatment over 6 months was developed and applied to 79 psoriasis patients. All the tested formulations presented a shear-thinning behavior with power law indexes (n) lower than 1. Ointments were distinct from the other dosage forms, since they presented higher consistency coefficients (K), firmness, and adhesiveness and this was evidenced by hierarchical cluster analysis, which identified two clusters based on the mechanical properties. Cluster 1 included the ointments and petrolatum and the cluster 2 enclosed the creams and the gel. The clusters were associated with several attributes classified by patients as analyzed with Fisher's exact test. In all cases, higher satisfaction was observed for cluster 2. The knowledge obtained regarding the influence of the dosage form on the degree of satisfaction with the treatment could be helpful in supporting the selection of the dosage form in clinical practice and thus improve treatment adherence and clinical outcomes. The differences observed between the mechanical properties of the formulations studied may be also relevant to the industry, as guidance to the development of new medicines.

Abstract
Background: Patient preferences should be considered when prescribing topical treatments to drive up adherence and improve clinical outcomes. Objective: The aim of this work was to identify the most important attributes of topical medicines for psoriasis treatment in the patients' view, and explore the sociodemographic and clinical determinants of these preferences. Methods: A questionnaire for the evaluation of the relevancy given to specific attributes of topical medicines used for psoriasis treatment was developed (PSO-TOPAP) and was applied to a total of seventy-nine patients, members of the Portuguese Association of Psoriasis (PSOPortugal) or outpatients of a dermatology unit of a central hospital. Results: Overall, attributes belonging to the formulation and application domains were greatly valued over attributes related to the container. Only a small number of patient preferences was influenced by age, gender, duration of the disease and age at first diagnosis. Limitations: Our findings need to be verified in larger and more diverse patient samples before generalization can be made. Conclusion: The insight obtained in this work can provide guidance to pharmaceutical drug product design and has also the potential to improve patient care through the acknowledgment of patient preferences in clinical practice.

Abstract
Acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) are associated with disease-initiating stem cells that are not eliminated by conventional therapies. Transcriptomic analysis of stem and progenitor populations in MDS and AML demonstrated overexpression of STAT3 that was validated in an independent cohort. STAT3 overexpression was predictive of a shorter survival and worse clinical features in a large MDS cohort. High STAT3 expression signature in MDS CD34+ cells was similar to known preleukemic gene signatures. Functionally, STAT3 inhibition by a clinical, antisense oligonucleotide, AZD9150, led to reduced viability and increased apoptosis in leukemic cell lines. AZD9150 was rapidly incorporated by primary MDS/AML stem and progenitor cells and led to increased hematopoietic differentiation. STAT3 knockdown also impaired leukemic growth in vivo and led to decreased expression of MCL1 and other oncogenic genes in malignant cells. These studies demonstrate that STAT3 is an adverse prognostic factor in MDS/AML and provide a preclinical rationale for studies using AZD9150 in these diseases.

Abstract
The aim of this study was to know the physical, chemical and nutritional characteristics of Rubus sellowii (Rosaceae) fruits, known as blackberry, native plant mainly to Rio Grande do Sul State (RS), Brazil. For this, three different populations of this plant were selected and the fruits were analyzed through moisture, ash, titratable acidity, pH, lipids, fibers, carbohydrates, proteins, carotenoids, lycopene, ascorbic acid, aminogram and in vitro digestibility. Fruits showed high acidity (3.28 percent), ash and protein (1.02 and 0.93 percent) and higher ascorbic acid (38.43 mg per 100 g) if compared to Rubus cultivars. Due to Rubus sellowii nutritional properties, they provide benefits to human health.

Abstract
OBJECTIVE Prolactinomas are the most common functional pituitary tumour. Dopamine agonists (DA) are its principal treatment. The criteria that should guide therapy withdrawal and the factors that influence disease remission or relapse are not yet fully established. Our purpose is to evaluate the proportion of patients who attempted DA withdrawal, and to identify the factors that influence clinicians to try it. In addition, we aim to study the factors that are involved in prolactinoma remission/relapse after therapy withdrawal. METHODS We retrospectively evaluated 142 patients with prolactinoma diagnosis who had been treated exclusively with DA. Firstly, the patients were divided in two groups, according to whether DA withdrawal had been attempted, or not, and the factors that might predict clinicians' decision to discontinue the therapy were then analysed. Secondly, patients who attempted withdrawal were further divided into two subgroups, based on their remission or relapse status and predictors of remission were evaluated. RESULTS DA withdrawal was attempted in 35.2% of our patients. Females, subjects with lower initial serum prolactin (PRL) levels, those with microadenomas and those with longer treatment duration all had a higher probability of seeing their therapy discontinued. In the withdrawal group, the remission rate was 72%. Macroprolactinomas relapse more often than microprolactinomas (p < 0.05). The recurrence group had higher median initial serum PRL levels and a lower mean duration of therapy, however these variables did not reach statistical significance. CONCLUSION We found a low percentage of attempt of withdrawal of DA therapy in the subjects with prolactinoma. Our data confirms that DA therapy can be discontinued with a high remission rate. Tumour size was the main variable that affected the withdrawal outcome in our patients.

Abstract
There have been few reports of lupus erythematosus tumidus (LET) in the literature. Most of textbooks of dermatology or dermatopathology mention this entity only briefly, if at all. The authors describe an additional case of this underdiagnosed disorder that further supports its existence as a separate entity in the spectrum of the variants of chronic cutaneous lupus erythematosus. Although most cases are reported in the European countries, to our knowledge, this is the first case documented in Portugal. The clinical, photobiological and histological features as well as differential diagnosis, treatment and prognosis are also discussed.

Abstract
OBJECTIVE To assess the effects of an exercise-based cardiac rehabilitation programme on daily physical activity levels of patients following myocardial infarction. DESIGN Subanalysis of two randomised, prospective controlled trials. SETTING Outpatient clinic of a secondary hospital. PARTICIPANTS Fifty consecutive patients randomised to the exercise group {n=25; 23 males; mean age 54 [standard deviation (SD) 9] years} or the control group [n=25; 20 males; mean age 58 (SD 9) years]. INTERVENTIONS The exercise group participated in an 8-week aerobic exercise programme plus usual medical care and follow-up. The control group received usual medical care and follow-up. MAIN OUTCOME MEASURES The primary outcome measure was change in time spent undertaking moderate-to-vigorous physical activity per day, assessed by accelerometer over 7 consecutive days. Secondary outcome measures were cardiorespiratory fitness, body mass, and resting blood pressure and heart rate. RESULTS Moderate-to-vigorous physical activity levels increased significantly in the exercise group [43.2 (SD 36.3) to 53.5 (SD 31.9) minutes/day, P=0.030], and remained unchanged in the control group [40.8 (SD 26.2) to 36.8 (SD 26.5) minutes/day, P=0.241] from baseline to the end of the programme. Cardiorespiratory fitness increased significantly in the exercise group (mean difference 2.8; 95% of the difference 1.3 to 4.4ml/kg/minute, P=0.001) after the 8-week programme. CONCLUSIONS In patients under optimal medication following myocardial infarction, participation in an 8-week exercise-based cardiac rehabilitation programme was found to improve physical activity levels consistent with health-related benefits. Future studies are needed to determine whether the increase in physical activity is maintained in the long term.

Abstract
The release of reactive oxygen and nitrogen species (ROS and RNS) during the inflammatory response generates damages to host tissues, referred to as immunopathology, and is an important factor in ecological immunology. The integrated antioxidant system, comprising endogenous antioxidant enzymes (e.g. superoxide dismutase SOD, and catalase CAT) and dietary antioxidants (e.g. carotenoids), helps to cope with immune-mediated oxidative stress. Crustaceans store large amounts of dietary carotenoids for yet unclear reasons. While being immunostimulants and antioxidants, the interaction of these pigments with antioxidant enzymes remains unclear. Here, we tested the interaction between dietary supplementation with carotenoids and immune challenge on immune defences and the activity of the antioxidant enzymes SOD and CAT, in the amphipod crustacean Gammarus pulex. Dietary supplementation increased the concentrations of circulating carotenoids and haemocytes in the haemolymph, while the immune response induced the consumption of circulating carotenoids and a drop of haemocyte density. Interestingly, supplemented gammarids exhibited down-regulated SOD activity but high CAT activity compared to control ones. Our study reveals specific interactions of dietary carotenoids with endogenous antioxidant enzymes, and further underlines the potential importance of carotenoids in the evolution of immunity and/or of antioxidant mechanisms in crustaceans.
