Abstract
Background In patients with established heart failure (HF) low total cholesterol levels associate with worse prognosis. Evidence concerning the impact of Low-density lipoprotein cholesterol (LDL-c) in HF is scarce. We aimed to evaluate the prognostic impact of LDL-c in patients with HF, both with and without diabetes mellitus (DM). Methods We retrospectively analyzed outpatients with chronic HF with systolic dysfunction followed in our HF clinic from January/2012 to May/2018. LDL-c was calculated using the Friedewald's formula. Patients without a complete lipid profile were excluded. The endpoint under analysis was all-cause mortality. Patients were followed until January/2021. A Cox-regression analysis was used to study the prognostic impact of LDL-c. The LDL-c cut-off used was 100 mg/dL (mean value). Analysis was stratified according to the coexistence of DM. Multivariate models were built adjusting for age, sex, coronary artery disease, atherosclerotic non-coronary artery disease, arterial hypertension, smoking status, statin use, severity of systolic dysfunction, creatinine clearance and evidence-based therapy. Results We studied 522 chronic HF patients, mean age was 70 years, 66.5% males. Severe systolic dysfunction was present in 42.7%, 30.5% had coronary heart disease, 60.5% had arterial hypertension, 41.6% had DM. A total of 92.0% were treated with beta blocker, 87.5% with an ACEi/ARB and 29.1% with a MRA. During a median follow-up of 53 (interquartile range 33-73) months, 235 (45%) patients died. Patients with LDL-c ≤100 mg/dL presented increased multivariate-adjusted risk of all-cause mortality: HR = 1.58 (95% CI: 1.08-2.30), p = 0.02. When patients were stratified according to DM, LDL-c ≤100 mg/dL was independently associated with increased death risk - HR = 1.55 (95% CI:1.05-2.30), p = 0.03 in patients without DM; in patients with DM no association was detected - multivariate-adjusted HR = 1.18 (95% CI: 0.77-1.80), p = 0.44. Conclusion Non-DM HF patients with LDL-c>100 mg/dL have a 35% reduction in the mortality risk when compared with those with lower values. The "cholesterol paradox" in HF also applies to LDL-c in non-DM patients.

Abstract
Additive Manufacturing (AM) demonstrates significant potential with rapid growth and widespread industrial adoption. To support the integration and innovation of AM technologies, the development of guidance tools and support methods are crucial, and a technological roadmap can assist in this effort. Despite its widespread use in production processes, the need for further research on the potential impact of AM remains significant. The full impact of AM is still uncertain and lacks consensus, highlighting the need for increased knowledge and investment from the scientific community and organizations. While the benefits of AM are recognized, the challenges of its adoption are not entirely known. AM will bring changes in the way organizations create, distribute, and derive value. Thus, in this article, a roadmap for AM is proposed and presented as a tool to map technological knowledge on the implementation and evolution of AM and serve as a strategic guide for organizations. The methodology for its elaboration involves three phases: planning and preparation, roadmap development, and review and update. Through a literature review, database and project consultation, and questionnaires to Portuguese companies that use AM in their production process it was possible to characterize the AM technology and through the visual format, based on a time horizon, summarize in a common framework all the information about the current and future state of AM in Portugal. The results of this study show that research and development initiatives are essential to promote the evolution of knowledge of the AM technology. Throughout this study and with the development of the roadmap it is anticipated that in the near future the AM will be widely used for prototyping and manufacturing of components and may be used for direct production in the short to medium term. It was also found that the main obstacles to the implementation of AM are the economic/productivity factors and the shortage of professionals with knowledge and skills in the area.

Abstract
Abstract
Background
Aortic stenosis (AS) is one of the main valvular heart diseases in developed countries. Degenerative fibrocalcific aortic stenosis is a progressive disease of the valve and ultimately of the myocardium, which can be fatal when symptomatic. There is no medical treatment that can halt or delay its progression. AS does not evolve linearly over time, and not every patient has the same progression rate.
Aims
The aim of this study is to 1) compare different mathematical models of aortic stenosis progression, 2) cluster patients into rapid and slow progressors and explore possible predictors, 4) evaluate the impact of different progression rates on cardiac structure and function, and 5) evaluate survival and optimal timing for follow-up and treatment.
Methods
We retrospectively studied consecutive patients with aortic peak velocities from 2012 to 2020. Follow-up echocardiograms, seriated biomarker assessment, and clinical records were consulted, providing a multiparametric data frame for longitudinal and dynamic modeling of aortic stenosis progression and its consequences.
Results
This study included 9583 studies from 752 patients with a median total follow-up of 4.26 years (interquartile range: 1.28 to 7.24 years). A logistic model was selected with the best accuracy to predict the rate of AS progression. Patients were categorized into slow and rapid progressors in a ratio of 5:1. Multiparametric analysis showed no association between these profiles and clinical variables. However, anti-hypertensive drugs before and after adjustment for blood pressure control (Calcium Channel Blockers, p=0.013, OR 0.50) were associated with slower progression. Meanwhile, elevated inflammatory markers (erythrocyte sedimentation rate, p=0.01) were associated with faster AS progression. Despite no survival difference between these groups, higher rates of valvular intervention were registered in rapid progressors (p<0.001). Moreover, faster progressors were associated with earlier cardiac damage (as demonstrated by early onset of moderate mitral and tricuspid valve regurgitation, left auricle dilation, and left ventricle hypertrophy, p<0.05).
Conclusions
These results can potentially modify follow-up times and deliver more personalized and individualized health care to different AS patients, thereby optimizing resources.

Abstract
Abstract
Introduction
Cardiovascular disease is an important cause of maternal mortality worldwide. However, diagnosing heart failure (HF) during pregnancy remains challenging. Patients with HF present with symptoms that are often attributed to the physiological changes of pregnancy. Although the measurement of natriuretic peptides (such as NT-proBNP) has been recommended as a cost-effective screening test for HF, its value in predicting underlying structural heart disease on echocardiography during pregnancy is unclear.
Purpose
To evaluate the accuracy of point-of-care (POC) NT-proBNP to predict echocardiographic evidence of structural heart disease in pregnant women.
Methods
All consecutive consenting pregnant women with symptoms of HF (New York Heart Association functional class [NYHA FC] II–IV), who underwent echocardiography at Groote Schuur Hospital (a tertiary hospital in South Africa) between 1 March 2021 and 15 March 2022 were recruited and compared with asymptomatic pregnant women (NYHA FC I). Demographic and obstetric data were collected, as well as clinical and echocardiographic parameters. POC NT-proBNP was measured; a receiver operating characteristic (ROC) curve was used to determine the level of NT-proBNP that would have the best predictive value for detecting structural heart disease on echocardiography.
Results
We included 121 women with a median age of 31.3 years (IQR 24.9–36.4) and a median gravidity of 3 (2–4), mostly in their third trimester of pregnancy (75.2%). Symptomatic women (66.1%) presented mainly with dyspnoea (92.5%) and fatigue (73.8%). Most common signs of HF were peripheral oedema (46.8%), jugular venous distension (17.7%) and pulmonary crackles (17.7%). Overall, the median POC NT-proBNP was 98pg/ml (60–506) but was not statistically different between symptomatic and asymptomatic participants. However, NT-proBNP levels were significantly elevated in those with left ventricular (LV) dilatation (376 [86–744] vs 65 [60–191], p=0.001), left atrial enlargement (395 [65–744] vs 60 [59–108], p<0.001), LV systolic dysfunction (510 [113–1668] vs 65 [60–210], p<0.001), diastolic dysfunction (300 [77–1450] vs 78 [60–257], p=0.031), mitral regurgitation (167 [60–672] vs 78 [60–243], p=0.038) and pericardial effusion (440 [81–1031] vs 71 [60–243], p=0.011) (Figure 1). An NT-proBNP of <200pg/ml had the highest negative predictive value (83%) to rule out structural heart disease (AUC 0.68 [0.59–0.77]). Patients with NT-proBNP of ≥200pg/ml were at increased risk of having echocardiographic evidence of structural heart disease (diagnostic odds ratio 4.9 [95% confidence interval 2.0–11.7]).
Conclusion
In this cohort of pregnant women with symptoms suggestive of HF, POC NT-proBNP identified those with structural heart disease with acceptable discrimination. POC NT-proBNP testing might be particularly useful as a screening test in settings where pregnant women do not readily have access to echocardiography.

Abstract
Abstract
Background
Obstructive sleep apnea (OSA) is a risk factor for development of atrial fibrillation (AF). Recent pacemakers have specific algorithms for detecting of OSA based on impedance measurement.
Purpose
The aim was to determine the burden of AF in patients with high respiratory disturbance index (RDI). It was also intended to determine if the onset of continuous positive airway pressure (CPAP) reduced the AF burden.
Methods
Retrospective observational study carried out through the analysis of the patient records. It included patients with pacemakers evaluated in an outpatient clinic during the first 8 months of 2018. All had the RDI algorithm. AF burden was assessed according to automatic mode switch (AMS) duration. The percentage of nights with an RDI>20/h was analysed to assess the risk of OSA.
Results
108 patients were included (mean age=70.3±9.0 years; 56.5% men). The most prevalent indication for cardiac pacing was atrioventricular node dysfunction (59.3%). The average percentage of nights with an RDI>20/h was 44.2%. The average follow-up (FU) period was 4.1 years.
Of all cardiovascular risk factors, diabetes mellitus was the only one associated with a higher incidence of AF at FU (p=0.044).
Considering just the patients with an RDI >20/h in more than 20% of nights (RDI20%), male gender was associated with higher rate of major adverse cardiovascular events [(acute myocardial infarction, stroke, acute heart failure and death) (p=0.019)].
Considering patients with AF prior to pacemaker implantation (n=34), 76% of patients had an RDI >20/h in more than 20% of nights (mean of 58.1%). 23 of these patients had long standing persistent AF at the end of FU (vs 17 at the beginnig of FU).
Considering patients who developed AF after pacemaker implantation (n=24), 58% of patients had an RDI>20/h in more than 20% of nights (mean of 45.3%). Most patients had paroxismal AF (83%).
Patients with prior paroxysmal AF or those who developed AF during FU (n=37) had a higher burden of AF at the end of FU when they had RDI >20/h in more than 50% of nights (mean burden of 24.66% vs 14.69%, p=0.005).
There was no statistically significant correlation between the percentage of nights with RDI >20/h and the Apnea Hypopnea Index (AHI) value. Patients who underwent polysomnography (n=30) had a mean AHI of 16/h (which corresponds to moderately severe OSA). 63% of patients who were referred from the pacemaker consultation to pneumology and performed polysomnography started CPAP.
CPAP use was not associated with a statistically significant reduction in any endpoints or AF burden.
Conclusion
A high RDI was associated with onset of de novo AF and higher AF burden in patients with paroxysmal AF. Thus, there is a rationale for early diagnosis and treatment of OSAS to prevent and reduce AF progression.
In this study, CPAP was not shown to significantly reduce this endpoint, probably due to reduced polysomnography and CPAP treatment.

Abstract
Introduction We live in a global world, where immigration is no longer just an escape, but also a demand and a desire. Globalization imposes the challenge of recognizing psychiatric illness in the most diverse of patients. Objectives To review the literature about the documentation of ethnic differences and the psychotic symptoms presentation. Methods We performed a MEDLINE search using the key words: ethnic differences and psychotic symptoms. We only included studies with full text published in English. Results
Since the 1970s, some studies have shown that there are differences in the manifestation of psychiatric illness in ethnic minorities. Most recent studies confirm this statement, mainly with an increase in immigration in the 20th century, with the receiving countries having an increase in the number of cases of psychosis (affective and non-affective). Belonging to an ethnic minority increases the risk of psychotic symptoms and experiences, witch is related to the patients perception of discrimination, social differences, family separation and the stress associated with immigration. On the other hand, these groups also have less access to health care. Conclusions Currently, professionals are more aware of the global world and what this implies in the manifestations of psychiatric illnesses. However, more studies will be needed to identify these natural differences. In this way, we will be able to help our patients anywhere and support their families.

Background
Behavioral and emotional factors may trigger cardiovascular events (CVE). Watching sports when there is an emotional connection between the supporters and the supportive team, is believed to be potentially associated with CVE. However, epidemiological studies have been inconsistent, with several studies showing an increase in CVE, while others reporting a protective effect.
Purpose
To assess the effect of watching sport events on the incidence of cardiovascular events.
Methods
Pubmed, and Embase were systematically searched to identify appropriate articles. Reference lists were then hand searched for additional relevant articles. To be included, articles had to assess the association between CVE and sport events supporters (adeptos). Pooled association measures, using random effects analysis, were calculated for mortality; arrhythmias; myocardial infarction (MI). Subgroup analysis was conducted based on gender. Publication bias and between-study heterogeneity were evaluated.
Results
There were nineteen studies included in the analysis. The pooled relative risks for mortality, arrhythmias and MI were 1.45(0.98-2.15; 95%CI; I2=70%; p=0.02); 1.31(0.98-1.77; 95%CI; I2=85%; p<0.01); 1.11(0.98-1.24; 95%CI; I2=91%; p<0.01) respectively (Figure 1A). The null association persisted in the subgroup analyses by gender for mortality (Figure 1B) as well as for MI and for the combined endpoint MI/stroke (non significant relative risks).
Conclusions
Overall this analysis suggests that watching sport events does not increase cardiovascular events regardless of gender.

Introduction
All individuals with a history of acute coronary syndrome (ACS) should receive intensive statin therapy in order to achieve the desirable low-density lipoprotein cholesterol (LDL-C) values recently modified in the guidelines of the European Society of Cardiology.
Purpose
To evaluate the lipid profile control of ACS patients with 6 year follow-up.
Methods
Retrospective study of 138 consecutive patients (P) admitted in our hospital for ACS during one year: 63 ± 13 years, 76.8% male, 26.9% with history of coronary artery disease and 56.5% of dyslipidemia. A 6 year follow-up was performed and a therapeutic goal was defined as LDL-C values below 55mg/dL and an LDL-C reduction of ≥50% from baseline, according to the guidelines of the European Society of Cardiology. High/moderate/low intensity statins were defined according to the therapeutic recommendations of the American College of Cardiology. Univariate analysis was performed.
Results
The mean LDL-C value at ACS admission was 112.5 ± 36.9mg/dL. 96.4% of patients were discharged on statins: 41.3% with rosuvastatin 10mg, 15.2% with simvastatin 20mg, 15.2% with atorvastatin 10mg, 10.9% with pitavastatin 2mg and 6.5% with atorvastatin 20mg.
Antidislipidemic therapy was changed in 7.9% of patients in the scheduled evaluation 1 month after discharge.
The mean LDL-C value after a 6 year follow-up was 83.6 ± 27.2mg/dL, with 85.8% P not meeting the defined therapeutic goal. Most of them (97.5%) continued medicated with statin, however, only 28.3% of P were on high-intensity statins and 3.8% were on low-intensity statins, despite the verified statistically significant association between LDL-C values and statin type used (high/medium/low intensity, p < 0.05).
Conclusion
Despite the proven benefit of statins, especially in high-risk patients, there are still aspects to improve, notably in the establishment of more effective therapies in order to achieve the desired new goals.

Abstract
Reproduction of Trachurus picturatus off the western Portuguese coast was studied over 1 yr. During histological analyses, the presence of Kudoa sp. was detected in advanced vitellogenic oocytes. Kudoa infections are known to cause economic loss through the induction of post-mortem liquefaction of fish muscles, but ovarian infection as reported in this study will seriously affect the reproductive potential of the species and thus impact fisheries productivity. Only females showed gonad infection which led to total degradation of advanced vitellogenic oocytes. No macroscopic, somatic or condition indices revealed differences between infected and uninfected females, rendering this infection event a concealed suppression of reproduction.

Abstract
Background and aims:In meridional European countries such as Portugal, informal caregivers are almost always close relatives, either key-relatives (those more involved) or not. There are few systematic comparisons between the experience of key-relatives/primary caregivers (PC) and other/secondary caregivers (SC) in psychogeriatrics. We present some preliminary data from the FAMIDEM (Families of People with Dementia) survey.Methods:Non-randomised cross-sectional study comparing two related samples of caregivers (PC versus SC) of 41 patients with DSM-IV dementia from outpatient practices in Lisbon (Portugal). Caregivers’ assessments included: Zarit Burden Interview, Caregiver Activity Survey (CAS), Positive Aspects of Caregiving, GHQ-12, Social Network Questionnaire and Dementia Knowledge Questionnaire.Results:Patients’ mean age was 78,7 years (SD 7,9). 24 (58,5%) were women and 58,5% had Alzheimer disease.PC were older than SC (p=0,000) and tended to live with the patient (p=0,000). They reported less emocional support (p=0,021) but higher objective burden-CAS (p=0,002). Regarding all other outcome variables, significant differences between groups were not found. Within the global sample, comparing spousals (n=23) and adult children/other relatives (n=59) yielded interestingly different preliminary results, eg higher GHQ-12 levels (p=0,010).Conclusions:The experience of caregiving is possibly different regarding PC and SC, but further research is warranted in order to define who really is at risk. Being a spouse may be much more determinant, although most spouses are PC as well. for the moment, it seems prudent not to exclude SC from risk assessments. the final FAMIDEM results, even lacking generalizability, will probably provide interesting clues.

Abstract
We present a case of a 57-year-old male with previously known primary severe mitral regurgitation, who was admitted to the ICU due to massive venous thromboembolism with associated right ventricle dysfunction and with two large mobile right atrial thrombi (2.4 x 1.5 cm and 3.6 x 3.7 cm). Despite of five days with a therapeutic aPTT achieved with unfractionated heparin (UFH), a TTE showed deterioration of the right ventricle systolic function, persistence of the right atrial masses with similar dimensions together with new mobile thrombi on the coronary sinus and on the right pulmonary artery. Due to deterioration of his clinical condition and given the refractoriness to the classical treatment with UFH, it was decided to administer an ultra-slow low-dose thrombolysis protocol, which consisted in a 24-hour infusion of 24 mg of alteplase at a rate of 1 mg per hour, without bolus. The treatment was continued by 48 consecutive hours, with clinical improvement and important reduction of the right atrial masses with resolution of the coronary sinus and right pulmonary artery thrombi. The patient started hypocoagulation with warfarin bridging with low molecular weight heparin (LMWH). Seven days after alteplase discontinuation there was complete resolution of the intracardiac thrombi. One month after ICU admission a successful mitral valve replacement surgery was conducted. Three months after discharge, the patient is in functional New York Heart Association (NYHA) class I with no cardiovascular events or hospitalizations. This case demonstrates that ultra-slow low-dose thrombolysis is a valid bailout treatment option in patients with large intracardiac thrombi refractory to anticoagulation.

Abstract
Two hundred and seven individuals (103 females and 104 males) of bluemouth Helicolenus dactylopterus (Scorpaeniformes, Sebastidae), a commercially important deep-water species with an unusual reproductive strategy, from the eastern Atlantic Ocean ranging from 13·9 to 37·5 cm total length (LT ) were analysed from September 2011 to October 2012. The analysis included gonad maturity phases and blood-plasma levels of oestradiol-17β (E2 ), 11-ketotestosterone (11-KT) and 17,20β-dihydroxypregn-4-en-3-one (17,20β-P). Results confirmed the existence of an annual reproductive cycle with asynchrony between females and males and a spawning season from January to May. A pronounced peak in 17,20β-P in October for both sexes was associated with possible mating behaviour and recent copula. Levels of E2 increased preceding the elevation of the gonado-somatic index during ovarian growth and were lower during regression and regeneration. The frequency distribution of oocyte-embryonic stages and variation of hormone levels suggest the existence of daily rhythms. Fertilization was detected between 2000-0000 and 0800-1200 h and spawning took place throughout the day peaking between 2000 and 0000 h. The cyclic pattern of sex steroids and ovarian recruitment provides a new insight into the reproductive strategy of this species.

Abstract
IntroductionAnorexia nervosa (AN) is characterized by self-induced starvation coupled with fear of gaining weight and a distorted body image. Its treatment is complex and challenging, and sometimes hospitalization is needed.Santa Maria Hospital's Eating Disorders Unit (SMH-EDU) is a multidisciplinary team, formed in 1989, that provides both outpatient and inpatient treatment.ObjectiveTo present and discuss SMH-EDU's AN treatment and its results.MethodsRevision and statistical analysis of all hospitalized AN’ patients’ clinical files, from 1 January 2014 to 31 December 2014. Treatment outcome was assessed by BMI variation.ResultsA total of 45 admissions (41 patients) were analysed: 75.65% had AN restricting type and 24.45% had AN purging type. All patient were females, with median age of 27 years old (range 12–57 years). Average admission BMI was 14.51 kg/m2 (ranging from 11.19 to 17.77 kg/m2). The mean lengths of stay were 39 days. Thirty-six percent of the patients had at least one previous hospitalization. Only 2 patients were readmitted at SMH-EDU: triple readmissions. The mean time between the beginning of the disorder and the admission was 111 months (ranging 2 to 408 months). Average discharged BMI was 16.32 kg/m2 (ranging from 13.24 to 19.11 kg/m2).ConclusionInpatient treatment for AN at SMH-EDU is considered only for those patients whose disorder has not improved with appropriate outpatient treatment. Therefore, most inpatients at SMH-EDU have disorders of high severity, as demonstrated in our results.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
INTRODUCTION To report a case of premacular hemorrhage treated with Neodymium (Nd):YAG laser puncture. CASE REPORT A 54 year-old Caucasian female was seen in the emergency department with complaints of sudden loss of vision in her right eye (RE), detected on the previous day. The best-corrected visual acuity (BCVA) in the RE was reduced to light perception, and fundoscopy evidenced a large and dense premacular hemorrhage. An Nd:YAG laser puncture was performed that day to drain the hemorrhage into the vitreous cavity. The intravitreal hemorrhage cleared in about 1 month, and the BCVA of the RE was 20/25 after 3 months.

Abstract
INTRODUCTION The use of guidelines for neonatal parenteral nutrition (PN) improves its clinical efficiency and the safety of prescription. OBJECTIVE To evaluate the practices of neonatal parenteral nutrition prescription in Portugal, and the adherence to the National Consensus on neonatal PN (2008). METHODS A questionnaire based on a multiple choice response on parenteral nutrition prescription was conducted, and sent to the coordinators of the 50 public and private Portuguese neonatal special care units, 25 being level III and 25 level II. RESULTS Parenteral nutrition was prescribed in 32 neonatal units, 23 of which (71.9%) responded to the questionnaire. Of the respondents, 19 (82.6%) refer to follow the National Consensus, the remaining following local guidelines; 17 (73.9%) of units referred to using an electronic based system for prescription. In preterm neonates, most mentioned: administering judiciously the fluid intake during the first post-natal week; starting amino acids from the first post-natal day with 1.5-3g/kg/d, increasing up to 3-4g/kg/d; starting lipids from the first three post-natal days with 1g/kg/d, increasing up to 3g/kg/d; administering 40-70mg/kg/d of calcium and of phosphorus with the fixed calcium:phosphorus ratio of 1.7: 1 (mg:mg); and estimating the osmolality of the solutions, and weekly monitoring of serum triglycerides, blood urea, serum phosphorus and liver function. CONCLUSIONS The high response rate is probably representative of the practice of PN prescription in Portugal. Most of the units used the National Consensus on neonatal PN as a reference, thus contributing to better nutritional support for neonates.

Abstract
Plasmodium malariae is a protozoan parasite that causes malaria in humans and is genetically indistinguishable from Plasmodium brasilianum, a parasite infecting New World monkeys in Central and South America. P. malariae has a wide and patchy global distribution in tropical and subtropical regions, being found in South America, Asia, and Africa. However, little is known regarding the genetics of these parasites and the similarity between them could be because until now there are only a very few genomic sequences available from simian Plasmodium species. This study presents the first molecular epidemiological data for P. malariae and P. brasilianum from Brazil obtained from different hosts and uses them to explore the genetic diversity in relation to geographical origin and hosts. By using microsatellite genotyping, we discovered that of the 14 human samples obtained from areas of the Atlantic forest, 5 different multilocus genotypes were recorded, while in a sample from an infected mosquito from the same region a different haplotype was found. We also analyzed the longitudinal change of circulating plasmodial genetic profile in two untreated non-symptomatic patients during a 12-months interval. The circulating genotypes in the two samples from the same patient presented nearly identical multilocus haplotypes (differing by a single locus). The more frequent haplotype persisted for almost 3 years in the human population. The allele Pm09-299 described previously as a genetic marker for South American P. malariae was not found in our samples. Of the 3 non-human primate samples from the Amazon Region, 3 different multilocus genotypes were recorded indicating a greater diversity among isolates of P. brasilianum compared to P. malariae and thus, P. malariae might in fact derive from P. brasilianum as has been proposed in recent studies. Taken together, our data show that based on the microsatellite data there is a relatively restricted polymorphism of P. malariae parasites as opposed to other geographic locations.

Abstract
In this study, the characterisation of radiation exposure of paediatric patients in computerised tomography (CT) procedures was performed for a Portuguese hospital. Dosimetric data and technical parameters used for CT examinations were retrieved, compiled and analysed over a period of 1 y. Five paediatric age groups were considered, covering the age interval from 0 (newborn) to 18 y old and, for each age group, the relative frequency of the most frequent CT examinations (head, ears, sinuses, chest and abdomen examinations) is analysed. The exposure settings used (kilovolt and milliampire) were compared with the values established in the local (hospital) clinical protocols for consistency analysis. Average CT dose index(vol) and dose length product values, per age group, are presented as well as the corresponding estimated mean effective dose values. Results showed an evident need for a protocol review, in order to adjust practices to international guidelines for performing optimised paediatric CT examinations. Also, an increased awareness of staff to Radiological Protection principles in CT in particular, these of utmost importance, seems necessary.

Abstract
Much of the analytical modeling of morphogen profiles is based on simplistic scenarios, where the source is abstracted to be point-like and fixed in time, and where only the steady state solution of the morphogen gradient in one dimension is considered. Here we develop a general formalism allowing to model diffusive gradient formation from an arbitrary source. This mathematical framework, based on the Green's function method, applies to various diffusion problems. In this paper, we illustrate our theory with the explicit example of the Bicoid gradient establishment in Drosophila embryos. The gradient formation arises by protein translation from a mRNA distribution followed by morphogen diffusion with linear degradation. We investigate quantitatively the influence of spatial extension and time evolution of the source on the morphogen profile. For different biologically meaningful cases, we obtain explicit analytical expressions for both the steady state and time-dependent 1D problems. We show that extended sources, whether of finite size or normally distributed, give rise to more realistic gradients compared to a single point-source at the origin. Furthermore, the steady state solutions are fully compatible with a decreasing exponential behavior of the profile. We also consider the case of a dynamic source (e.g. bicoid mRNA diffusion) for which a protein profile similar to the ones obtained from static sources can be achieved.

Abstract
The NA60 experiment at the CERN Super Proton Synchrotron has studied dimuon production in 158A GeV In-In collisions. The strong excess of pairs above the known sources found in the complete mass region 0.2<M<2.6 GeV has previously been interpreted as thermal radiation. We now present first results on the associated angular distributions. Using the Collins-Soper reference frame, the structure function parameters lambda, mu, and nu are measured to be zero, and the projected distributions in polar and azimuth angles are found to be uniform. The absence of any polarization is consistent with the interpretation of the excess dimuons as thermal radiation from a randomized system.

Abstract
The aim of this study is a comparison between two different adolescents’ consultations: NES Consultation, which assists youngsters from 11 to 21 years old with self-destructive behaviours and Adolescence Consultation, which assists adolescents from 13 to 21 years old, without any specific diagnose or psychopathology.Our sample it is composed of 100 youngsters, 15 males and 35 females from NES C (average age 15.5) and 14 males and 36 females from AC group (average age 15.6).Data was collected from semi-structure interviews (at the assessment moment) and clinical documentation forms, analysed with SPSS program, through qui-square test (nominal variables).Major findings: absence of significant differences between youngsters who cut themselves in the two consultations; in reported difficulties category, the hypothesis that there would be significant differences between the two groups was not fully confirm, it figured to be only true for school difficulties sub-category; significant differences found on depressive syndromatic diagnose sub-category; the results on source of reference category showed a significant difference between the groups we studied; the number of adolescents from the AC who have previously had suicidal ideation, although significantly different from NES C, can't be disregard. Inquiring about suicidal ideas and thoughts whenever attending an adolescent in difficulties should be the standard, not the exception, recognizing that we will not be able to bring to an end suicide but listening and understanding the suffering adolescent, we can win some time, and at the meantime, plenty of things can change.

Abstract
The NA60 experiment at the CERN SPS has studied low-mass dimuon production in 158A GeV In-In collisions. An excess of pairs above the known meson decays has been reported before. We now present precision results on the associated transverse momentum spectra. The slope parameter Teff extracted from the spectra rises with dimuon mass up to the rho, followed by a sudden decline above. While the initial rise is consistent with the expectations for radial flow of a hadronic decay source, the decline signals a transition to an emission source with much smaller flow. This may well represent the first direct evidence for thermal radiation of partonic origin in nuclear collisions.

Abstract
The NA60 experiment studies muon pair production at the CERN Super Proton Synchrotron. In this Letter we report on a precision measurement of J/psi in In-In collisions. We have studied the J/psi centrality distribution, and we have compared it with the one expected if absorption in cold nuclear matter were the only active suppression mechanism. For collisions involving more than approximately 80 participant nucleons, we find that an extra suppression is present. This result is in qualitative agreement with previous Pb-Pb measurements by the NA50 experiment, but no theoretical explanation is presently able to coherently describe both results.

Abstract
We report on a precision measurement of low-mass muon pairs in 158 AGeV indium-indium collisions at the CERN SPS. A significant excess of pairs is observed above the yield expected from neutral meson decays. The unprecedented sample size of 360,000 dimuons and the good mass resolution of about 2% allow us to isolate the excess by subtraction of the decay sources. The shape of the resulting mass spectrum is consistent with a dominant contribution from pi+pi- -->rho -->mu+mu- annihilation. The associated space-time averaged spectral function shows a strong broadening, but essentially no shift in mass. This may rule out theoretical models linking hadron masses directly to the chiral condensate.

Abstract
Traumatic bone cysts usually are found in young individuals and most frequently have the radiographic appearance of well-circumscribed radiolucent lesions with a tendency to scallop between the roots of the teeth. Two well-documented cases of traumatic bone cysts are presented in which some differences related to their radiographic features were observed. The possible explanations for these differences are discussed and a brief review of the literature regarding the main characteristics of traumatic bone cyst lesions also is provided.

Abstract
UNLABELLED Prevalence studies of anorexia nervosa (AN) have shown differences depending of the country and method applied. The partial syndrome is being emphasized. There has been no epidemiological study done on AN in the Portuguese population of continental Portugal. Our objectives were: 1) to study the prevalence of AN in Portuguese populations; 2) to study the presence of partial syndrome and of body image disturbance; 3) to calculate the number of girls dieting; 4) to correlate with other variables. A population of 2,398 girls ranging 10 to 21 years old, from 30 State secondary schools in the Lisbon and Setubal districts were studied. A questionnaire was answered with questions allowing assessment of all DSM IIIR criteria for AN. RESULTS Prevalence of AN--0.37%, partial syndrome--12.6%, body image disturbance without weight loss--7%, wish to decrease weight in normal or low weight girls--38%, overweight--15.3%, the peak of age for AN was 15 years, the most prevalent socio-economic class for AN was 2 (scale 1 (higher) to 5). School performance was worse with AN and the age menarche was sooner.

In the title mononuclear complex, [Cu(C(5)H(9)N(3))(C(10)H(15)N(5))](ClO(4))(2), the Cu(II) centre is surrounded by two N-donor ligands, which impose a square-pyramidal environment on the metal. The new tridentate ligand [2-(imidazol-4-yl)ethyl][(1-methylimidazol-2-yl)methyl]amine (HISMIMA) lies in the basal plane, while the histamine ligand occupies the apical and one of the basal positions around the Cu(II) ion.

Abstract
The impact on occult leukemia of GM-CSF as a sensitizing agent has not been studied. We treated 41 adult patients with de novo acute myeloid leukemia, 25 of whom achieved complete remission and were given 1 to 3 post-remission courses, each course including GM-CSF begun 4 days prior to chemotherapy and given until day 3. After a median follow-up of 32 months, the probability of remaining in continuous complete remission was 17% at 46 months. GM-CSF in this setting was not associated with an improved outcome, arguing against a priming effect.
