Abstract
The contribution of radiotherapy, per se, to late cardiotoxicity remains controversial. To clarify its impact on the development of early cardiac dysfunction, we developed an experimental model in which the hearts of rats were exposed, in a fractionated plan, to clinically relevant doses of ionizing radiation for oncological patients that undergo thoracic radiotherapy. Rat hearts were exposed to daily doses of 0.04, 0.3, and 1.2 Gy for 23 days, achieving cumulative doses of 0.92, 6.9, and 27.6 Gy, respectively. We demonstrate that myocardial deformation, assessed by global longitudinal strain, was impaired (a relative percentage reduction of >15% from baseline) in a dose-dependent manner at 18 months. Moreover, by scanning electron microscopy, the microvascular density in the cardiac apex was significantly decreased exclusively at 27.6 Gy dosage. Before GLS impairment detection, several tools (qRT-PCR, mass spectrometry, and western blot) were used to assess molecular changes in the cardiac tissue. The number/expression of several genes, proteins, and KEGG pathways, related to inflammation, fibrosis, and cardiac muscle contraction, were differently expressed in the cardiac tissue according to the cumulative dose. Subclinical cardiac dysfunction occurs in a dose-dependent manner as detected by molecular changes in cardiac tissue, a predictor of the severity of global longitudinal strain impairment. Moreover, there was no dose threshold below which no myocardial deformation impairment was detected. Our findings i) contribute to developing new markers and exploring non-invasive magnetic resonance imaging to assess cardiac tissue changes as an early predictor of cardiac dysfunction; ii) should raise red flags, since there is no dose threshold below which no myocardial deformation impairment was detected and should be considered in radiation-based imaging and -guided therapeutic cardiac procedures; and iii) highlights the need for personalized clinical approaches.

Abstract
BackgroundThe SARS-CoV-2 virus has caused a worldwide health crisis. Patients with inflammatory arthritis are at higher risk of hospitalization and death by COVID-19 due to comorbidities or immunosuppressive treatments. Vaccination is one the most important strategies to control the pandemic.ObjectivesTo evaluate the incident cases of SARS-CoV-2 infection in a multicentric cohort of inflammatory arthritis in Brazil.MethodsBiobadaBrasil is a multicentric registry-based cohort study of Brazilian patients with rheumatic diseases starting their first bDMARD or tsDMARD (1). The present analysis is a retrospective evaluation of adult patients with inflammatory arthritis (rheumatoid arthritis – RA, spondylarthritis -SpA and psoriatic arthritis-PsA) that were alive since the beginning of the COVID-19 pandemics in Brazil in February 2020. We evaluated the incidence and severity of COVID-19 infection and the adherence to anti- SARS-CoV-2 vaccines schedules, up to January 2022.ResultsA total of 300 patients were interviewed and 69 (23.0%) reported confirmed anti-SARS-CoV infection and 5 (1.7%) had a second infection. Among known infected patients, 18.8% need hospitalization and oxygen support, 7.2% were admitted at ICU, and 5.8% died. After COVID-19 infection, 31.8% reported worsening of disease activity but only 6.1% had modification in medication due to disease activity. Distribution of cases followed the pattern of waves observed in Brazil (Figure 1). Regarding vaccination, 285 (95%) reported to have received at least one dose of any anti-SARS-CoV-2 vaccine: 43% received the first with the adenovirus ChAdOx1 nCoV-19 (AstraZeneca) adenovirus vaccine, 32% received the Sinovac-CoronaVac inactivated vaccine, 22% received the BNT162b2 (Pfizer-BioNtech) mRNA vaccine and 3% received the BNT162b2 (Pfizer-BioNtech) adenovirus vaccine. Almost all (98.1%) of these patients had already received the second dose of vaccine and after the first and second vaccine doses, 6% and 4% of patients, respectively, reported worsening of articular disease activity, while, after the third dose, no patient reported disease activity worsening.Figure 1.ConclusionDuring the pandemics, patients with inflammatory arthritis had a pattern of distribution of cases very similar to general population. Adherence to vaccination is high and well tolerated.References[1]Bredemeier et al. J Rheumatol 2021;48:1519-27Disclosure of InterestsNone declared

Abstract
BackgroundThe effect of age on persistence and safety of treatment with biologic disease modifying anti-rheumatic drugs (bDMARDs) in rheumatoid arthritis has been a subject to research interest. Two recently published studies did not observe significantly different survival of treatment with bDMARDs among older age (≥ 65 years) individuals (1,2); incidence of serious adverse events was higher in these patients (2).Objectivesto evaluate association of the age with treatment survival and overall safety among patients receiving one or multiple courses of bDMARDs or targeted synthetic (ts-) DMARDs.MethodsBiobadaBrasil is a multicentric registry-based cohort study of Brazilian patients with rheumatic diseases starting their first bDMARD or tsDMARD (3). The present analysis includes RA patients recruited from Jan 2009 to Oct 2019, followed-up over one or multiple (up to six) courses of treatment necessarily involving a bDMARD or tsDMARD (latest date, Nov 19, 2019). Treatment course is defined as a period during which the medication scheme does not change, except for dose adjustments. Primary outcome was the incidence treatment interruption for any reason (except for pregnancy or disease remission), while interruption due to adverse events (AEs; including death) and due to inefficacy served as secondary outcomes. Incidence of serious adverse events (SAEs) also served as a secondary outcome. Extended (frailty) multivariate Cox proportional hazards models and negative binomial regression with generalized estimating equations (to calculate incidence rate ratios [IRRs]) were used for statistical analyses (both types of analyses including time-varying covariates over multiple courses of treatment).ResultsIn total, 1316 patients (2335 treatment courses, 6508 patient-years [PY]) were enrolled. Of these, 160 patients (643 PY; 237 treatment courses) were ≥ 65 years old, mean age at starting treatment = 71 ± 5 yrs (84% female). Old age was not significantly associated with treatment interruption for any reason, but presented higher risk of interruption due to adverse events (after multivariate adjustment) and lower risk of stopping because of inefficacy (see Table 1). Older patients presented higher incidence of SAEs than younger ones (16.0 vs 8.4/100 PY, respectively; multivariate IRR: 2.06, 95% CI: 1.51 to 2.80, P<0.001). Among old patients, tocilizumab (HR: 2.73, 95% CI: 1.13 to 6.64, P=0.026), etanercept (2.13, 1.12 to 4.07, P=0.022), and infliximab (2.39, 1.19 to 4.79, P=0.014) presented higher risk of treatment termination as compared with adalimumab. In this subgroup (age ≥65 yrs), there was no significant difference in the risk of SAEs between different bDMARDs/tsDMARDs.Table 1.Univariate and multivariate hazard ratios (HRs) of interruption of treatment course comparing older (≥65 years) versus younger patients (reference category).

Abstract
BackgroundAntimalarials (AM) are frequently part of the initial scheme of conventional synthetic DMARDs in the treatment of rheumatoid arthritis (RA), and have been associated with lower incidence of diabetes and better lipid profile in these patients (1). However, the role of AM in schemes involving biologic (b-) or targeted synthetic (ts-) DMARDs has been much less extensively studied. In addition, a recent large scale study (2) and a consensus article (1) casted doubt on the long-term cardiovascular safety of AM.ObjectivesTo evaluate the association of concomitant use of AM with the overall safety and survival oftreatment course among patients receiving one or multiple courses of bDMARDs or tsDMARDsMethodsBiobadaBrasil is a multicentric registry-based cohort study of Brazilian patients with rheumatic diseases starting their first bDMARD or tsDMARD (3). The present analysis includes RA patients recruited from Jan 2009 to Oct 2019, followed-up over one or multiple (up to six) courses of treatment (latest date, Nov 19, 2019). A treatment course is defined as a period during which the medication scheme does not change. The primary outcome was the incidence of serious adverse events (SAEs). Total and system-specific adverse events (AEs), treatment interruption for any reason, interruption due to AEs and due to inefficacy served as secondary outcomes. Negative binomial regression with generalized estimating equations (to calculate the incidence rate ratios [ÌRRs]) and extended (frailty) Cox proportional hazards models were used for statistical analyses (both types of analyses including time-varying covariates over multiple courses of treatment).ResultsIn total, 1316 patients (2335 treatment courses, 6711 patient-years [PY]) were enrolled. The overall incidence of serious adverse events was 9.2/100 PY. AM were used over 354 courses (1254.5 PY) of therapy. The IRRs for the primary and secondary outcomes are presented in Table 1. AM were also associated with better treatment course survival (Figure 1), reducing the risk of interruption due to AEs (multivariate hazard ratio: 0.56, 95% CI: 0.39 to 0.81, P=0.002) and inefficacy (0.65, 0.48 to 0.87, P=0.003).Figure 1.Table 1.Univariate and multivariate incidence rate ratios (IRRs) of adverse events comparing use versus non-use (reference category) of antimalarials.

Abstract
Background:After failure of conventional synthetic disease modifying anti-rheumatic drugs (csDMARDs) in the therapy of rheumatoid arthritis (RA), treatment may be escalated to biologic (bDMARDs) or JAK inhibitors (JAKi) (1). Analysis of drug survival can provide useful information on the effectiveness of these therapeutic schemes.Objectives:to evaluate the association of the choice of therapeutic agent with the survival of treatment course in RA patients receiving their first bDMARD or JAKi.Methods:BiobadaBrasil is a multicentric registry-based cohort study of Brazilian patients starting their first bDMARD/JAKi (2). This analysis includes RA patients recruited from Jan 2009 to Oct 2019, followed-up over the first course of treatment with a bDMARD/JAKi until censoring (latest date, Nov 19, 2019) or occurrence of the outcome of interest. A treatment course is defined as a period during which the medication scheme does not change, except for dose adjustments. The primary outcome was the interruption of treatment course for any reason (except for pregnancy or disease remission); interruption of treatment due to adverse events (AEs) or death and due to inefficacy served as secondary outcomes. Multivariate Cox proportional hazards models were used for analyses.Results:In total, 1177 patients (3800 patient-years [PY]) were enrolled. The overall incidence of treatment interruption was 17.5/100 PY. Adalimumab was the most frequently prescribed agent, followed by infliximab (n= 267). The hazards ratios (HR) of the primary and secondary outcomes are presented in Table 1. Figure 1 compares the survival of treatment curves of different bDMARDs/JAKi.Table 1.Hazard ratios (HR) of interruption of therapy course of each therapeutic agent (the reference category for bDMARDs/ JAKi is infliximab).

Abstract
PURPOSE During radiotherapy the peritumoral tissues are daily exposed to subtherapeutic doses of ionizing radiation. Herein, the biological and molecular effects of doses lower than 0.8 Gy per fraction (LDIR), previously described as angiogenesis inducers, were assessed in human peritumoral tissues. MATERIAL AND METHODS Paired biopsies of preperitoneal adipose tissue were surgically collected from 16 patients diagnosed with locally advanced rectal cancer who underwent neo-adjuvant radiotherapy. One of the biopsies is located in the vicinity of the region where the tumor received the prescribed dose of radiation, and thus exposed to LDIR; the other specimen, outside all beam apertures, was used as an internal calibrator (IC). Microvessel density (MDV) was quantified by immunohistochemistry and the expression of angiogenic, pro-inflammatory, adhesion and oxidative stress genes was assessed by quantitative RT-PCR using exclusively endothelial cells (ECs) isolated by laser capture microdissection microscopy. RESULTS LDIR activated peritumoral ECs by significantly up-regulating the expression of several pro-angiogenic genes such as VEGFR1, VEGFR2, ANGPT2, TGFB2, VWF, FGF2, HGF and PDGFC and down-regulating the pro-inflammatory IL8 marker. Accordingly, the MVD was significantly increased in peritumoral tissues exposed to LDIR, compared to the IC. The patients that yielded a larger pro-angiogenic response, also showed the highest MVD. CONCLUSIONS LDIR activate ECs in peritumoral tissues that are associated with increased MVD. Although the technological advances in radiotherapy have contributed to reduce the damage to healthy tissues over the past years, the anatomical regions receiving LDIR should be taken into account in the treatment plan report for patient follow-up and in future studies to correlate these doses with tumor dissemination.

Abstract
The molecular structure of the medieval watercolor known as folium has finally been solved in the 21st century. The interdisciplinary approach taken was the key to producing extracts that had been prepared following medieval instructions, and shows the blue/purple chromophore as the major dye in Chrozophora tinctoria fruits (shell). A multi-analytical characterization of its structure was made using HPLC-DAD-MS, GC-MS, NMR (1H, 13C, COSY, HSQC, HMBC, INADEQUATE), and computational studies. The results demonstrate that the blue compound corresponds to 6'-hydroxy-4,4'-dimethoxy-1,1'-dimethyl-5'-{[3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl]oxy}-[3,3'-bipyridine]-2,2',5,6(1H,1'H)-tetraone, a hermidin derivative, which we named chrozophoridin. Experimental data and computational modeling studies show that this mono-glycosylated dimer is represented by two stable isomers (atropisomers). This is an indispensable piece of knowledge for the characterization of this medieval dye in works of art such as medieval manuscript illuminations and for testing its stability and contributes to the preservation of our cultural heritage.

Abstract
At low doses, ionizing radiation activates endothelial cells and promotes angiogenesis. However, it is still unknown if other cells may contribute to this process. In this study, the effect of low-dose ionizing radiation (LDIR) in modulating the pro-angiogenic potential of adipocytes was investigated. Adipocytes are known to secrete multiple angiogenic factors and adipokines that induce angiogenesis. In this work, a confluent monolayer of 3T3-L1 pre-adipocytes was exposed to low doses (0.1 and 0.3 Gy) and to higher doses (0.5, 0.8 and 1.0 Gy), as control. Our data show that the adipocyte-conditioned media (A-CM) from mature adipocytes differentiated from low-dose irradiated pre-adipocytes presented a higher angiogenic potential, compared to mature adipocytes differentiated from sham-irradiated control preadipocytes. The vascular endothelial growth factor (VEGF)-A levels were significantly increased in A-CM from the 0.1 Gy (P < 0.05) and 0.3 Gy (P < 0.01) experimental conditions and a significant increase was found in response to 0.3 Gy dose of radiation for VEGF-C, angiopoietin-2 (ANG-2) and hepatocyte growth factor (HGF). Moreover, 0.3 Gy dose of radiation significantly increased the expression of matrix metalloproteinase (MMP)-2 active forms. In vitro, the A-CM from the 0.1 and 0.3 Gy doses experimental conditions significantly accelerated endothelial cell migration after an in vitro wound healing assay. Importantly, in vivo, the A-CM corresponding to the 0.3 Gy experimental condition significantly induced the growth of more blood vessels towards the inoculation area in the chick embryo chorioallantoic membrane (CAM). In conclusion, this work reveals a new mechanism by which low-dose radiation might promote angiogenesis, enhancing the angiogenic potential of A-CM.

Abstract
Aims We have previously shown that low-dose ionizing radiation (LDIR) induces angiogenesis but there is no evidence that it induces neovascularization in the setting of peripheral arterial disease. Here, we investigated the use of LDIR as an innovative and non-invasive strategy to stimulate therapeutic neovascularization using a model of experimentally induced hindlimb ischemia (HLI). Methods and results After surgical induction of unilateral HLI, both hindlimbs of female C57BL/6 mice were sham-irradiated or irradiated with four daily fractions of 0.3 Gy, in consecutive days and allowed to recover. We demonstrate that LDIR, significantly improved blood perfusion in the murine ischemic limb by stimulating neovascularization, as assessed by laser Doppler flow, capillary density, and collateral vessel formation. LDIR significantly increased the circulating levels of VEGF, PlGF, and G-CSF, as well as the number of circulating endothelial progenitor cells (EPCs) mediating their incorporation to ischemic muscles. These effects were dependent upon LDIR exposition on the ischemic niche (thigh and shank regions). In irradiated ischemic muscles, these effects were independent of the recruitment of monocytes and macrophages. Importantly, LDIR induced a durable and simultaneous up-regulation of a repertoire of pro-angiogenic factors and their receptors in endothelial cells (ECs), as evident in ECs isolated from the irradiated gastrocnemius muscles by laser capture microdissection. This specific mechanism was mediated via vascular endothelial growth factor (VEGF) receptor signaling, since VEGF receptor inhibition abrogated the LDIR-mediated gene up-regulation and impeded the increase in capillary density. Finally, the vasculature in an irradiated non-ischemic bed was not affected and after 52 week of LDIR exposure no differences in the incidence of morbidity and mortality were seen. Conclusions These findings disclose an innovative, non-invasive strategy to induce therapeutic neovascularization in a mouse model of HLI, emerging as a novel approach in the treatment of critical limb ischemia patients.

Abstract
The Fishing House located on the grounds of the Marquis of Pombal Palace, Oeiras, Portugal, was built in the 18th century. During this epoch, Portuguese gardens, such as the one surrounding the Fishing House, were commonly ornamented with glazed wall tile claddings. Currently, some of these outdoor tile panels are covered with dark colored biofilms, contributing to undesirable aesthetic changes and eventually inducing chemical and physical damage to the tile surfaces. Phylogenetic analyses revealed that the investigated biofilms are mainly composed of green algae, cyanobacteria and dematiaceous fungi. With the aim of mitigating biodeterioration, four different biocides (TiO2 nanoparticles, Biotin® T, Preventol® RI 80 and Albilex Biostat® ) were applied in situ to the glazed wall tiles. Their efficacy was monitored by visual examination, epifluorescence microscopy and DNA-based analysis. Significant changes in the microbial community composition were observed 4 months after treatment with Preventol® RI 80 and Biotin® T. Although the original community was inactivated after these treatments, an early stage of re-colonization was detected 6 months after the biocide application. TiO2 nanoparticles showed promising results due to their self-cleaning effect, causing the detachment of the biofilm from the tile surface, which remained clean 6 and even 24 months after biocide application. © 2013 Society for Applied Microbiology and John Wiley & Sons Ltd.

Abstract
The introduction of two amine substituents in 4' and 7 positions, leads to the formation of a blue flavylium cation, 7-(N,N'-diethylamino)-2-(9-julolidine)-1-benzopyrilium, which is extremely stable across a wide acidic pH range. The kinetic and thermodynamic constants of the multistate system have been calculated by studying the relaxation kinetics after equilibrium perturbation by addition of base (direct pH jumps) or acid (reverse pH jumps). Except for the cis-chalcone, which is an elusive species, the relative energy levels of the other species could be calculated and a global energy level diagram constructed. The diagram explains that the stability of the diamino compound is due to the high energy level of the hemiketal species, which is difficult to access in acidic medium.

Abstract
e15172 Background: Gastric carcinoma is the second cause of cancer mortality worldwide. In Portugal, a country with a high incidence of the disease, it is also the second leading cause of cancer mortality. The gravity of this situation and the advanced stage of disease at presentation warrants a search of a new prognostic indicator. We studied in patients (pts) with gastric cancer, both diffuse and intestinal types, several possible prognostic indicators, such as: weight, nutrition status, Ki-67, p53, Cerb2, and cadherin E. The results showed that Ki-67, an indicator of cell proliferation, may play an important role as a prognostic indicator because it is easily assessed by immunohistochemistry, is observed in both intestinal and in diffuse tumor types, and is related with tumor size, depth of invasion and the pattern of lymphatic spread. Methods: A total of 50 pts with gastric carcinoma (25 diffuse and 25 intestinal types) undergoing radical gastrectomy with extended lymphadenectomy (D2 and a few D3 types ) were prospectively studied by immunohistochemistry for the determination of Ki-67 in biopsied tissue and gastrectomy specimens. A relationship between the Ki-67 and various other prognostic factors, like histological tumor type, tumor location, number of involved lymph nodes, depth of invasion, sex and stage was established. Results: A total of 50 tumor specimens and an equal number of biopsies were evaluated for Ki-67 overexpression. Ten tumors (20%) presented a Ki-67 < 50%, 13 tumors (26%) showed a Ki-67 >50% < 74%, and 27 tumors (54%) had a Ki-67 > 75%. It was found that tumors with a low Ki-67 expression have a more proximal location, the histological type was either mixed or diffuse, tend to invade superficially the gastric wall, they don’t have metastases in distal lymph nodes, and are diagnosed in early stages of the disease. Conclusions: In this study, the Ki-67 overexpression showed prognostic value in both diffuse and intestinal type gastric cancer patients.

Abstract
PURPOSE Prostate cancer (PCa) is one of the most commonly diagnosed malignancies in the world. Although PSA utilization as a serum marker has improved prostate cancer detection it still presents some limitations, mainly regarding its specificity. The expression of this marker, along with the detection of PCA3 mRNA in urine samples, has been suggested as a new approach for PCa detection. The goal of this work was to evaluate the efficacy of the urinary detection of PCA3 mRNA and PSA mRNA without performing the somewhat embarrassing prostate massage. It was also intended to optimize and implement a methodological protocol for this kind of sampling. MATERIALS AND METHODS Urine samples from 57 patients with suspected prostate disease were collected, without undergoing prostate massage. Increased serum PSA levels were confirmed by medical records review. RNA was extracted by different methods and a preamplification step was included in order to improve gene detection by Real-Time PCR. RESULTS An increase in RNA concentration with the use of TriPure Isolation Reagent. Despite this optimization, only 15.8% of the cases showed expression of PSA mRNA and only 3.8% of prostate cancer patients presented detectable levels of PCA3 mRNA. The use of a preamplification step revealed no improvement in the results obtained. CONCLUSION This work confirms that prostate massage is important before urine collection for gene expression analysis. Since PSA and PCA3 are prostate specific, it is necessary to promote the passage of cells from prostate to urinary tract, in order to detect these genetic markers in urine samples.

Abstract
e14673 Background: Lymph node Metastases play a major role as an independent prognostic factor in gastric cancer. Presence of distal lymph node metastases assumes a pejorative prognostic significance, and represents a problem in terms of therapeutic approach. For this reason it’s of major interest to find predictive markers of distal lymph node chain involvement. The P53 tumor suppressor gene, a product of the TP53 gene works normally as a brake on DNA replication, as suppressor of angiogenesis and triggering of apoptosis. The gene most frequently mutated in gastric cancer is the TP53, that is responsible for the production of P53 mutant protein, which forms inactive complex with the native protein, and manifest by the overexpression of p53 in immunocytochemistry. The overexpression of P53 gene has been considered a bad prognostic factor associated mainly with lymph node metastases. Methods: This study seeks to determine the relation between the expression of P53 and the presence of distal lymph node metastases as an indicator for an extended lymphadenectomy. A total of 50 patients undergoing surgery with D2 lymphadenectomy for gastric carcinoma with curative intent were enrolled in this work. Therefore it was evaluated in 1,786 lymph nodes the correlation between the P53 expression with tumor location, size, histological type, depth , number of nodes involved, number of distal lymph node metastases and the TNM stage. Results: In all parameters, mutant P53 protein related with indicators of poor prognosis. In particular has demonstrated a statistical significant correlation (p=0.019) with the presence of distal lymph node metastases. The main objective of this study which was finding a prognostic predictor of distal nodal metastases has been reached. Conclusions: Mutant P53 protein is a good prognostic indicator, for the presence of distal lymph node involvement in gastric carcinoma.

Abstract
BACKGROUND Skeletal-related events (SREs) occur frequently in patients with bone metastases as a result of breast (BC) and prostate (PC) cancers. They increase both morbidity and mortality and lead to extensive health-care resource utilization. METHODS Health care resource utilization by BC/PC patients with at least one SRE during the preceding 12 months was assessed through retrospective chart review. SRE-treatment costs were estimated using the Portuguese Ministry of Health cost database and analyzed using generalized linear models. RESULTS This study included 152 patients from nine hospitals. The mean (SD) annual SRE-treatment cost per patient was €5963 (€3646) and €5711 (€4347), for BC (n=121) and PC (n=31) patients, respectively. Mean cost per single episode ranged between €1485 (radiotherapy) and €13,203 (spinal cord compression). Early onset of bone metastasis (P = 0.03) and diagnosis of bone metastases at or after the occurrence of the first SRE (P < 0.001) were associated with higher SRE-treatment costs. CONCLUSION These results reveal the high hospital SRE-treatment costs, highlighting the need for early diagnosis and treatment, and identify key factors determining the economic value of therapies for patients with skeletal metastases.

Abstract
Trial 24, one of three ongoing trials in the Early Prostate Cancer programme, is evaluating the efficacy and tolerability of bicalutamide (Casodex) 150 mg following standard care (radiotherapy, radical prostatectomy or watchful waiting) in patients with early, non-metastatic prostate cancer. At 7 years' median follow-up, addition of bicalutamide significantly improved objective progression-free survival (PFS) for patients with locally advanced disease, reducing the risk of progression by 34% versus standard care alone (hazard ratio 0.66; 95% confidence interval 0.55, 0.79; P<0.001). In localized disease, a significant difference in objective PFS was not found. There was no significant difference in overall survival.

Abstract
Trial 24 is one of three placebo-controlled trials within the ongoing bicalutamide ('Casodex') Early Prostate Cancer (EPC) programme evaluating bicalutamide 150 mg/day in addition to radical prostatectomy, radiotherapy or watchful waiting for T1b-4, any N, M0 prostate cancer. In Trial 24, at 5.1 y median follow-up, the addition of bicalutamide significantly (P < 0.0001) improved objective progression-free survival (PFS) and prostate-specific antigen PFS compared with standard care alone. There was no significant difference in overall survival (P = 0.746). In the context of the whole EPC programme, long-term bicalutamide is not appropriate for localised disease, yet provides advantages in delaying disease progression in patients with locally advanced prostate cancer.

Abstract
The international decline in gastric cancer is mainly attributed to improved socio-economic conditions. However, some southern and eastern European countries showed slower and later decline, reflecting a less favourable general environment The same probably applies to regional differences within countries, making national indicators potentially misleading. Fitting log-linear Poisson models we compared trends in gastric cancer mortality (1984-1999) across 18 Portuguese regions. Pearson correlation coefficients were computed to assess the regional association between decline in cancer mortality and baseline cancer mortality and variation in indices of social development and medical care. National gastric cancer mortality changed -2.0% year in men and -2.2% year in women. The regional yearly variation in mortality ranged from -3.5% [95% confidence interval (CI) -4.5 to -2.5] to -0.6% (95% CI -1.4 to 0.2) in men, and from -3.7% (95% CI -4.8 to -2.7) to -0.8% (95% CI -1.6 to 0.0) in women. Regional variation was not significantly associated with baseline gastric cancer mortality (r = 0.18, P = 0.47), but with the variation in post-neonatal mortality (r = 0.59, P = 0.01). In Portugal, gastric cancer shows a wide regional variation in frequency trends. The correlation with known indicators of social and economic development indicates that future improvement in gastric cancer rates is expected in parallel with a more widespread development.

Abstract
In this work a new water-soluble long-lifetime chemosensor, containing a polyamine unit connected to a complexed Ru(II) metal center, is described. Its crystal structure has been characterized by X-ray analysis. The polyamine macrocyclic unit is capable of anchoring cationic or anionic substrates, according to its protonation state. Examples of electron transfer involving the ruthenium complex core and the bound substrate are presented. The photocatalytic ability of such a system is illustrated by the oxidation of iodide to iodine promoted by light absorption at 436 nm.

This ligand is constituted by an aliphatic polyamine chain and a coordinating cleft, delimited by two dipyridine units, where the metal ion is lodged. The resulting complexes are characterized by an unusually high stability. The polyamine chain is not involved, or weakly involved, in metal coordination, and facile protonation can occur on the nitrogen atoms of this moiety. Similar coordination features are found in the Eu(III) complex. A fluorescence emission study reveals that the Eu(III) cryptate shows the characteristic visible emission of the metal, due to the intramolecular energy transfer to the metal ion mainly from the lower energy triplet state of the cryptand. On the other hand, the emission intensity is modulated by pH, giving a maximum at neutral pH and decreasing at both acidic and alkaline pH values.

Abstract
OBJECTIVES To investigate the efficacy and tolerability of bicalutamide (Casodex) as immediate therapy, either alone or as adjuvant to treatment of curative intent, in patients with localized or locally advanced (T1b-T4, any nodal status, M0) prostate cancer. METHODS This was a multicenter, prospective, randomized, double-blind, placebo-controlled trial in Europe, South Africa, Australia, and Mexico and is part of the Casodex Early Prostate Cancer program. RESULTS A total of 3603 men were randomized to receive bicalutamide (n = 1798) or placebo (n = 1805). The patient demographics were well balanced between the two groups. Prior therapy of curative intent had been given to 64% of the patients (prostatectomy [44%], radiotherapy [18%], and prostatectomy and radiotherapy [2%]) and 36% had been monitored with watchful waiting. After a median follow-up of 2.6 years and a median exposure to the study drug of 2.2 years, a significant 43% reduction in the risk of objective progression was observed for the bicalutamide group compared with the placebo group (hazard ratio 0.57, 95% confidence interval 0.48 to 0.69, P << 0.0001). The time to prostate-specific antigen doubling was significantly delayed for the bicalutamide group compared with the placebo group (hazard ratio 0.37, 95% confidence interval 0.32 to 0.43, P << 0.001). The survival data were immature, with 7.2% overall mortality. The most frequently reported adverse events with bicalutamide were gynecomastia alone (17.4%), breast pain alone (17.6%), and gynecomastia with breast pain (47.5%). CONCLUSIONS Bicalutamide 150 mg daily as immediate therapy, alone or as adjuvant to treatment of curative intent, significantly reduced the risk of disease progression in patients with localized or locally advanced prostate cancer. Longer follow-up is underway to assess any benefit in overall survival.

Abstract
The synthesis of the macrocyclic ligand 4,4'-(2,5,8,11,14-pentaaza[15])-2,2'-bipyridylophane (L3), which contains a pentaamine chain linking the 4,4'-positions of a 2,2'-dipyridine moiety, is reported. Protonation and Zn(II) complexation by L3 and by macrocycle L2, containing the same pentaamine chain connecting the 6,6'-positions of 2,2'-dipyridine, were studied by means of potentiometric, UV-vis, and fluorescent emission measurements. While in L2 all the nitrogen donor atoms are convergent inside the macrocyclic cavity, in L3 the heteroaromatic nitrogen atoms are located outside. Both ligands form mono- and dinuclear Zn(II) complexes in aqueous solution. In the mononuclear Zn(II) complexes with L2, the metal is coordinated inside the macrocyclic cavity, bound to the heteroaromatic nitrogen donors and three amine groups of the aliphatic chain. As shown by the crystal structure of the [ZnL2](2+) complex, the two benzylic nitrogens are not coordinated and facile protonation of the complex takes place at slightly acidic pH values. Considering the mononuclear [ZnL3](2+) complex, the metal is encapsulated inside the cavity, not coordinated by the dipyridine unit. Protonation of the complex occurs on the aliphatic polyamine chain and gives rise to translocation of the metal outside the cavity, bound to the heteroaromatic nitrogens.

Abstract
This work was developed in the Paranoá city town of the Federal District of Brazil. It used techniques of participative research with the aim of reducing intestinal helminths transmission in a group of children at nutritional risk. The family nucleus, that is, parents, children and other relatives living together in the same house, was used as reference for this research. All steps of the work were followed simultaneously by technical and educative actions. The technical actions were related to faecal examinations and medication. The educative process, stimulated critical analysis and reflections on the central problem and life conditions, with a strong focus on Health Promotion to improve life quality, as well as an empowerment process. During the work development, of the action program included the following steps: home visits, interviews, group meetings, feedback on the faeces examinations results and treatment. An evaluation of the final results was made through quantitative and qualitative methods, which showed the construction, acquisition and socialisation of knowledge.
