Abstract
Abstract
Introduction Resveratrol (RSV) is a natural phytoalexin present in abundance in grapes, berries, peanuts and red wine. The main benefits of resveratrol ingestion are due to its anti-inflammatory and antioxidant properties. This compound also induces therapeutic benefits in the remodelling of extracellular matrix (ECM), which plays an important role in the regulation of the activity of matrix metalloproteinases (MMPs) and its tissue inhibitors of metalloproteinases (TIMPs). The MMPs are a family of zinc dependent endopeptidases, with an important role in the physiological and pathological remodelling of ECM, once the activity of MMPs can be regulated by TIMPs. This regulation is essential, since if there is an imbalance between the MMPs and TIMPs there’s destruction of the ECM, leading to the development of several pathologies.
Objectives Evaluate RSV potential by determining serum and salivary levels of MMP-10 and TIMP-1.
Methodology The study population included 27 undergraduates between the ages of 18 and 30, divided into a control group (placebo) and an intervention group, supplemented with 100 mg RSV/day, during 30 days. MMP-10 and TIMP-1 levels were determined by slot blot. The results were analysed using a GraphPad Prism version 5 software for Windows (GraphPad Software, San Diego, California, USA).
Results It was verified the existence of a linear correlation between the serum and salivary levels of TIMP-1, as well as a tendency of increase of this biomarker after RSV supplementation. In all indicators studied, supplementation with this compound wasn’t harmful.
Conclusion The rising trend verified at TIMP-1 in both fluids may reflect benefits in the individuals under study, demonstrating that saliva has potential as a study biofluid for this type of biochemical markers. It was also verified that supplementation with this compound did not damage the evaluated parameters and, therefore, the RSV potential shouldn’t be rejected.

Abstract
Cancer stem cells (CSC) are a small population with self-renewal and plasticity which are responsible for tumorigenesis, resistance to treatment and recurrent disease. This population can be identified by surface markers, enzymatic activity and a functional profile. These approaches per se are limited, due to phenotypic heterogeneity and CSC plasticity. Here, we update the sphere-forming protocol to obtain CSC spheres from breast and gynecological cancers, assessing functional properties, CSC markers and protein expression. The spheres are obtained with single-cell seeding at low density in suspension culture, using a semi-solid methylcellulose medium to avoid migration and aggregates. This profitable protocol can be used in cancer cell lines but also in primary tumors. The tridimensional non-adherent suspension culture thought to mimic the tumor microenvironment, particularly the CSC-niche, is supplemented with epidermal growth factor and basic fibroblast growth factor to ensure CSC signaling. Aiming for robust identification of CSC, we propose a complementary approach, combining functional and phenotypic evaluation. Sphere-forming capacity, self-renewal and sphere projection area establish CSC functional properties. Additionally, characterization comprises flow cytometry evaluation of the markers, represented by CD44+/CD24- and CD133, and Western blot, considering ALDH. The presented protocol was also optimized for primary tumor samples, following a sample digestion procedure, useful for translational research.

Abstract
BACKGROUND AND PURPOSE The mechanism by which β3 receptor agonists (e.g. mirabegron) control bladder overactivity may involve adenosine release from human and rat detrusor smooth muscle. Retrograde activation of adenosine A1 receptors reduces ACh release from cholinergic bladder nerves. β3 -Adrenoceptors usually couple to adenylyl cyclase. Here we investigated, which of the cAMP targets, protein kinase A or the exchange protein directly activated by cAMP (EPAC) could be involved in this cholinergic inhibition of the bladder. EXPERIMENTAL APPROACH [3 H]ACh and adenosine release from urothelium-denuded detrusor strips of cadaveric human organ donors and rats were measured by liquid scintillation spectrometry and HPLC, respectively. In vivo cystometry was also performed in urethane-anaesthetized rats. KEY RESULTS The exchange protein directly activated by cAMP (EPAC) inhibitor, ESI-09, prevented mirabegron- and isoprenaline-induced adenosine release from human and rat detrusor strips respectively. ESI-09, but not the PKA inhibitor, H-89, attenuated inhibition of [3 H]ACh release from stimulated (10 Hz) detrusor strips caused by activating β3 -adrenoceptors, AC (forskolin) and EPAC1 (8-CTP-2Me-cAMP). Isoprenaline-induced inhibition of [3 H]ACh release was also prevented by inhibitors of PKC (chelerythrine and Go6976) and of the equilibrative nucleoside transporter 1 (ENT1; dipyridamole and NBTI), but not by PLC inhibition with U73122. Pretreatment with ESI-09, but not with H-89, prevented the reduction of the voiding frequency caused by isoprenaline and forskolin in vivo. CONCLUSION AND IMPLICATIONS Data suggest that β3 -adrenoceptor-induced inhibition of cholinergic neurotransmission in human and rat urinary bladders involves activation of an EPAC1/PKC pathway downstream cAMP production resulting in adenosine outflow via ENT1.

Abstract
The Mental Health Continuum-Short Form (MHC-SF) is a self-report questionnaire that allows the assessment of positive mental health, including three well-being components-emotional, psychological and social-as well as the categorical diagnosis of the presence or absence of mental health. The purpose of this study is to describe the adaptation and validation of the Portuguese version of MHC-SF and to examine whether this is an adequate measure of positive mental health for the Portuguese context. The participants included 1448 respondents between the ages of 18 and 94 (M = 33.15; SD = 16.3), 70.1% of which were females. Results confirm the reliability (α = .93), tripartite factor structure, and the external and internal validity of the MHC-SF. Data also supported the two-continuum model, with positive mental health and mental illness belonging to two correlated but distinct dimensions. These findings indicated that the Portuguese MHC-SF is valid instrument to measure well-being and positive mental health.

Abstract
Aging is a social and economic challenge of the highest importance and a multidisciplinary intervention seems to be a promising approach for improving the quality of life of elderly individuals. This project was designed aimed at promoting an active and healthy aging through the implementation of an intervention program based on the comprehensive geriatric assessment model (AGA@4life), focused on promoting health and wellbeing, independence and autonomy, mobility, and social inclusion. A non-randomized interventional study was designed to evaluate the effect of only a dietetic and nutritional approach (control group (CG)) and the combination of a tailored exercise program and a dietetic and nutritional approach (intervention group (IG)) in the biochemical and hematological profile of older adults in the framework of AGA@4life. The 34 participants enrolled, aged 65 years or over, were subject to a thorough baseline (T0) multidisciplinary diagnostic evaluation, including the gathering of clinical information and a battery of biochemical and hematological determinations, and reevaluated after eight weeks of intervention (T1). Between T0 and T1, an increase in albumin and total proteins serum levels were observed in both groups (p < 0.01); the hematological profile in CG and IG showed an increase in red cell count and hemoglobin (p < 0.05). In IG, an increase of HDL cholesterol (p < 0.001) and a decrease of triglycerides (p = 0.001) were still observed. The AGA@4life multidisciplinary intervention improved the hematological and biochemical profile of old adults, potentially contributing to delay the development of several aging comorbidities and increase the quality of life of participants.

Abstract
Chromatin state is highly dependent on the nucleosome binding proteins. Herein, we used a multipronged approach employing biophysical and in vivo experiments to characterize the effects of Nucleosome Binding Peptides (NBPeps) on nucleosome and cell activity. We performed a series of structure-based calculations on the nucleosome surface interaction with GMIP1 (a novel NBPep generated in silico), and HMGN2 (nucleosome binding motif of HMGN2), which contains sites that bind DNA and the acid patch, and also LANA and H4pep (nucleosome binding motif of H4 histone tail) that only bind to the acidic patch. Biochemical assays shows that H4pep, but not HMGN2, GMIP1 and LANA, is highly specific for targeting the nucleosome, with important effects on the final nucleosome structure and robust in vivo effects. These findings suggest that NBPeps might have important therapeutic implications and relevance as tools for chromatin investigation.

Abstract
The objective of this study was to investigate the role of ATP in cholinergic neurotransmission in the urinary bladder of control men and of patients obstructed as a result of benign prostatic hyperplasia (BPH). Human detrusor samples were collected from 41 patients who submitted to transvesical prostatectomy resulting from BPH and 26 male organ donors. The release of [3H]acetylcholine ([3H]ACh) was evoked by electrical field stimulation (10 Hz, 200 pulses) in urothelium-denuded detrusor strips. Myographic recordings were performed to test detrusor strip sensitivity to ACh and ATP. Nerve-evoked [3H]ACh release was 1.5-fold higher in detrusor strips from BPH patients compared with controls. This difference was abolished after desensitization of ionotropic P2X1-3 receptors with an ATP analog, α,β-methylene ATP (30 μM, applied for 15 minutes). TNP-ATP (10 nM, a preferential P2X2/3 antagonist) and A317491 (100 nM, a selective P2X3 antagonist) were about equipotent in decreasing nerve-evoked [3H]ACh release in control detrusor strips, but the selective P2X1 receptor antagonist NF023 (3 μM) was devoid of effect. The inhibitory effect of TNP-ATP (10 nM) increased from 27% ± 9% to 43% ± 6% in detrusor strips of BPH patients, but the effect of A317491 (100 nM) [3H]ACh release unaltered (20% ± 2% vs. 24% ± 4%). The amplitude of ACh (0.1-100 μM)-induced myographic recordings decreased, whereas sensitivity to ATP (0.01-3 mM) increased in detrusor strips from BPH patients. Besides the well characterized P2X1 receptor-mediated contractile activity of ATP in pathologic human bladders, we show here for the first time that cholinergic hyperactivity in the detrusor of BPH patients is facilitated by activation of ATP-sensitive P2X2/3 heterotrimers. SIGNIFICANCE STATEMENT: Bladder outlet obstruction often leads to detrusor overactivity and reduced bladder compliance in parallel to atropine-resistant increased purinergic tone. Our data show that P2X1 purinoceptors are overexpressed in the detrusor of patients with benign prostatic hyperplasia. Besides the P2X1 receptor-mediated detrusor contractions, ATP favors nerve-evoked acetylcholine release via the activation of prejunctional P2X2/3 excitatory receptors in these patients Thus, our hypothesis is that manipulation of the purinergic tone may be therapeutically useful to counteract cholinergic overstimulation in obstructed patients.

Abstract
Abstract
Background
The presence of an acute coronary syndrome (ACS) is per se a predictor of reduced responsiveness to clopidogrel; in particular, patients with ST-elevation myocardial infarction (STEMI) have impaired clopidogrel-induced platelet inhibition than those with other forms of ACS. However, the impact of the type of ACS on the pharmocodynamic efficacy of more potent P2Y12 antagonists such as prasugrel or ticagrelor has not been fully elucidated to date.
Purpose
To assess the impact of the type of ACS on platelet inhibition mediated by P2Y12 receptor antagonists in the acute and the maintenance phase of therapy in a contemporary cohort of ACS patients undergoing percutaneous coronary intervention (PCI).
Methods
Substudy of a prospective, national, multicentre, pharmacodynamic registry conducted in a population of ACS patients undergoing PCI and treated with dual antiplatelet therapy including aspirin and a P2Y12 inhibitor as per clinical indication. Patients were classified according to the ACS diagnosis into groups: a) STEMI, b) non-ST-elevation ACS (NSTEACS), c) unstable angina (UA), and d) other (excluded from the present analysis). Platelet function tests (PFT) were performed at day 1 and day 30 (±5) after PCI and included: 1) VerifyNow P2Y12 assay, expressed as P2Y12 reaction units (PRUs); 2) Vasodilator-stimulated phosphoprotein (VASP) assay; and 3) Multiple electrode aggregometry (MEA).
Results
A total of 965 patients (372 with STEMI, 395 with NSTEACS and 198 with UA) were included in the present substudy. At day 1, the proportions of patients with each type of ACS according to the P2Y12 inhibitor received were: 1) clopidogrel (n=317): STEMI 35.0%, NSTEACS 34.4% and UA 30.6%; 2) prasugrel (n=192): STEMI 70.3%, NSTEACS 17.7% and UA 12.0%; 3) ticagrelor (n=456): STEMI 27.6%, NSTEACS 55.3% and UA 17.1%. A statistically significant reduced platelet inhibition, measured with the VerifyNow system, was observed in STEMI patients compared with the other forms of ACS in patients receiving clopidogrel (STEMI: 217.3±8.1, NSTEACS: 157.1±7.9 and UA: 164.9±8.6 PRUs; p for STEMI vs. NSTEACS <0.001 and p for STEMI vs. UA <0.001) and ticagrelor (STEMI: 57.7±3.8, NSTEACS: 45.2.1±2.6 and UA: 40.6±4.9 PRUs; p for STEMI vs. NSTEACS 0.008 and p for STEMI vs. UA 0.007), while a numerical trend towards greater platelet reactivity in STEMI compared to UA was observed in subjects receiving prasugrel (Figure). Remarkably, at day 30, no significant differences on platelet inhibition were observed according to the ACS type with any of the P2Y12 inhibitors. Similar results were observed with MEA and VASP assays.
PD response according to the ACS type
Conclusions
Patients presenting with STEMI have impaired platelet inhibition mediated by P2Y12 antagonists compared to other types of ACS during the acute phase of therapy, whereas no difference is observed during the maintenance phase of treatment.

Abstract
The concept of Developmental Assets links positive features of developmental ecologies with personal skills, competences and values in order to further the understanding of optimal development. The purpose of this research was to explore the relationship between the experience of Developmental Assets and adolescent's perception of Life Satisfaction. A convenience sample of 503 Portuguese students was evaluated, mean age of 15.92 years (SD = 1.17), 63% female gender. Findings revealed that both external and internal Developmental Assets are experienced differently across gender, grade and age. Results indicate that 74% of the adolescents report their Life Satisfaction to be in the positive range. Boys report significantly higher levels of Life Satisfaction than girls. Results show significant negative correlations between Life Satisfaction and age. The main effect of school grade on Life Satisfaction was not statistically significant. Findings revealed that 32 of the 40 Developmental Assets configured in the model showed a statistically significant positive relationship with Life Satisfaction. Also, results suggest that the greater the experience of Developmental Assets, the greater the Life Satisfaction. Stepwise regression was conducted to determine which Developmental Assets and demographic factors predict Life Satisfaction. Results suggest that the relationship between demographic variables and Life Satisfaction is weak, contributing modestly to the prediction of Life Satisfaction (2%). Nine Developmental Assets emerged as independent and significant predictors of Life Satisfaction: Overall Self-esteem made the largest contribution, with Family Support, Planning and decision Making, Sense of Purpose, Positive Family Communication, Positive Values of Caring, Youth as Resources, School Engagement and Other Adult Relationships also yield significant predictability. The total regression model (Developmental Assets and demographic variables) explained 54% of the variance in Life Satisfaction results. The present findings suggest the applicability and utility of the framework as a strategy to foster positive development in adolescence.

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

Abstract
Disinfection by UV radiation is one of the most promising solutions to reduce the bacterial load and antibiotic resistance in the final effluents of urban wastewater treatment plants (UWTP). Our aim was to evaluate the fate of cefotaxime-resistant Enterobacteriaceae and Extended Spectrum Beta-Lactamase (ESBL) producers in a full-scale system that includes UV-C disinfection. Over treatment, the abundance of cefotaxime-resistant Enterobacteriaceae was reduced, with reductions of 1.9 log units after secondary treatment (STW samples) and 1.8 log following UV disinfection (UTW samples). These reductions, did not reflect the variations in the prevalence of cefotaxime-resistant Enterobacteriaceae, estimated to be of 3% in raw wastewater (RW), 18% in STW and 3% in UTW. A significant increase of cefotaxime-resistant bacterial counts (0.5 log; p < 0.05) was observed after 3 days of storage. In a total of 1799 cefotaxime-resistant Enterobacteriaceae isolates, 15% harboured blaCTX-M (n = 274), 11% blaTEM (n = 194) and 4% blaSHV (n = 72). While the ESBL gene prevalence decreased over treatment, the prevalence of the intI1 gene decreased after ST but slightly increased in UTW samples. The blaCTX-M-carriers were identified as Escherichia coli and Klebsiella pneumoniae, mostly multi-drug resistant (90.5%) and carrying integrase genes (82.8%). The blaCTX-M gene variants (48 blaCTX-M-15, 9 blaCTX-M-32, 8 blaCTX-M-1, 5 blaCTX-M-27, and 2 blaCTX-M-14) were flanked by ISEcp1, ISEcp1/IS26, IS903 and ORF477 in 8 different arrangements. The IncF plasmid replicon type was highly prevalent among blaCTX-M-carrying Escherichia coli (74.5%) while IncR predominated among K. pneumoniae (54.5%). Our results confirmed the potential of UV-C disinfection to remove antibiotic resistant bacteria. Still, resistant Enterobacteriaceae (about 30 × 106 cells per m3 of water), presenting traits that might potentiate antibiotic resistance spread, are released in the final effluent. In addition, a significant regrowth was observed after storage. These results suggest that improvements of wastewater disinfection are still required to minimize the risks associated with UWTP discharges.

Abstract
El modelo de Recursos del Desarrollo - "Developmental Assets®" - asocia características ecológicas positivas a competencias y valores personales con el propósito de comprender un desarrollo óptimo en la adolescencia. El objetivo de la presente revisión es describir, analizar y discutir los resultados de la utilización de este modelo. Como criterio de elegibilidad se definió la inclusión de estudios que exploran el modelo de Recursos del Desarrollo en el marco de la perspectiva del Desarrollo Positivo en la Adolescencia. Se consideró la investigación de publicaciones con recurso a las bases de datos electrónicas Web of Science, ERIC, Science Direct y SciELO, realizada entre marzo a mayo de 2017. En esta revisión se incluyeron 29 artículos publicados entre 1998 a 2015. Se verifica la adopción de diversos métodos en cuanto a la identificación de recursos, evaluación y aplicabilidad. El modelo demuestra ser culturalmente válido, relevante, en diferentes contextos y características socioeconómicas, sugiriéndose su aplicabilidad y utilidad como estrategia de un desarrollo positivo en la adolescencia.

Abstract
INTRODUÇÃO: O envelhecimento crescente da população e a necessária gestão de doentes cada vez mais complexos numa sociedade onde se esperam melhores resultados do ponto de vista custo-efetividade tem exigido aos serviços de saúde uma visão necessariamente mais multidisciplinar das especialidades.MÉTODOS: Neste artigo apresenta-se uma breve casuística de três meses da articulação direta diária entre ortopedistas e internistas, assentes numa prestação de cuidados integrados aos doentes internados por causas ortopédicas mas com necessidade de gestão de comorbilidades e/ou intercorrências significativas. Aborda-se ainda o protocolo das fraturas proximais do fémur criado por uma equipa de trabalho interdisciplinar no sentido de prestar melhores cuidados a uma situação ortopédica associada a considerável morbimortalidade.RESULTADOS: Na maioria dos casos os doentes estavam internados em contexto de patologia traumática e foram submetidos a tratamento cirúrgico. Destacaram-se a elevada faixa etária, a diversidade de comorbilidades, o número importante de infeções nosocomiais e a necessidade de gestão médica multidisciplinar. A maioria dos doentes exigiu acompanhamento regular.CONCLUSÃO: A perceção de doentes com elevado número de comorbilidades e outras entidades nosológicas a par do problema ortopédico salienta a necessidade de um acompanhamento mais holístico, onde certamente a Medicina Interna pode exercer um papel fundamental.
