- Abstract
Background: In keeping with the fundamental practice of transparency in the discussion and resolution of ethics conflicts raised by research, a summary of ethics issues raised during Portuguese biomonitoring in health surveillance and research is presented and, where applicable, their resolution is described.Methods: Projects underway aim to promote the surveillance of public health related to the presence of solid waste incinerators or to study associations between human exposure to environmental factors and adverse health effects. The methodological approach involves biomonitoring of heavy metals, dioxins and/or other persistent organic pollutants in tissues including blood, human milk and both scalp and pubic hair in groups such as the general population, children, pregnant women or women attempting pregnancy. As such, the projects entail the recruitment of individuals representing different demographic and health conditions, the collection of body tissues and personal data, and the processing of the data and results.Results: The issue of autonomy is raised during the recruitment of participants and during the collection of samples and data. This right is protected by the requirement for prior written, informed consent from the participant or, in the case of children, from their guardian. Recruitment has been successful, among eligible participants, in spite of incentives rarely being offered. The exception has been in obtaining guardians' consent for children's participation, particularly for blood sampling. In an attempt to mitigate the harm-benefit ratio, current research efforts include alternative less invasive biomarkers.Surveys are currently being conducted under contract as independent biomonitoring actions and as such, must be explicitly disclosed as a potential conflict of interests. Communication of results to participants is in general only practised when a health issue is present and corrective action possible. Concerning human milk a careful approach is taken, considering breast-feeding's proven benefits.Conclusion: No national legislation currently accounts for the surveillance component of biomonitoring as distinct from research. Ethics issues arising within the domain of research are resolved according to available regulations. For issues encountered during surveillance, the same principles are used as guidance, completed by the authors' best judgement and relevant ethics committees' findings.

- Abstract
Background: Noninvasive ventilation (NIV) and High-flow nasal cannula (HFNC) are the main forms of treatment for acute respiratory failure. This study aimed to evaluate the effect, safety, and applicability of the NIV and HFNC in patients with acute hypoxemic respiratory failure (AHRF) caused by COVID-19., Methods: In this retrospective study, we monitored the effect of NIV and HFNC on the SpO
2 and respiratory rate before, during, and after treatment, length of stay, rates of endotracheal intubation, and mortality in patients with AHRF caused by COVID-19. Additionally, data regarding RT-PCR from physiotherapists who were directly involved in assisting COVID-19 patients and non-COVID-19., Results: 62.2 % of patients were treated with HFNC. ROX index increased during and after NIV and HFNC treatment (P < 0.05). SpO2 increased during NIV treatment (P < 0.05), but was not maintained after treatment (P = 0.17). In addition, there was no difference in the respiratory rate during or after the NIV (P = 0.95) or HFNC (P = 0.60) treatment. The mortality rate was 35.7 % for NIV vs 21.4 % for HFNC (P = 0.45), while the total endotracheal intubation rate was 57.1 % for NIV vs 69.6 % for HFNC (P = 0.49). Two adverse events occurred during treatment with NIV and eight occurred during treatment with HFNC. There was no difference in the physiotherapists who tested positive for SARS-COV-2 directly involved in assisting COVID-19 patients and non-COVID-19 ones (P = 0.81)., Conclusion: The application of NIV and HFNC in the critical care unit is feasible and associated with favorable outcomes. In addition, there was no increase in the infection of physiotherapists with SARS-CoV-2., (Copyright © 2022 The Authors. Published by Elsevier B.V. All rights reserved.)- Published

- Abstract
Aims: To evaluate the systemic changes and autonomic cardiocirculatory control of awaken rats chronically exposed to the cigarette smoke (CS) of 1 or 2 cigarettes/day., Main Methods: Rats were exposed to clean air (control) or cigarette smoke of 1 (CS1) or 2 (CS2) cigarettes/animal/day for 30 days. Then, arterial pressure (AP) and heart rate (HR) were recorded in conscious rats to assess spontaneous baroreflex sensitivity and HR and AP variabilities. Evoked baroreflex and cardiac autonomic tone were evaluated by vasoactive drugs and autonomic blockers, respectively. In another group, ventilatory and cardiovascular parameters were recorded under hypoxia and hypercapnia stimulus. At the end of protocols, heart, lung, kidneys and liver were collected for histological analysis., Key Findings: Rats exposed to CS showed morphological changes, being more evident in the CS2 group. Also, less weight gain and cardiac hypertrophy were prominent in CS2 rats. Basal AP and HR, spontaneous baroreflex sensitivity and cardiovascular variabilities were similar among groups. CS exposure progressively blunted the bradycardia response to phenylephrine (-2.2 ± 0.1 vs. -1.7 ± 0.2 vs. -1.5 ± 0.2) while the tachycardia response to sodium nitroprusside was slightly increased compared to control. Vagal tone was not affected by CS, but CS2 rats exhibited higher sympathetic tone (-25 ± 4 vs. -28 ± 4 vs. -56 ± 9) and lower intrinsic HR (411 ± 4 vs. 420 ± 8 vs. 390 ± 6). Exposure to CS of 2 cigarettes also exacerbated the reflex cardiovascular and ventilatory responses to hypoxia and hypercapnia., Significance: CS exposure for 30 days promoted systemic changes and autonomic cardiocirculatory dysfunction in rats depending on the daily exposure dose., (Copyright © 2021 Elsevier Inc.

- Abstract
The population aging in Europe imposes challenges to societies that require adaptations and responses at various levels to minimize impacts and figuring out opportunities. Portugal has been committed to the World Health Organization and European Union's values and policy frameworks concerning active and healthy aging. In 2017, an inter-ministerial working group developed the National Strategy for Active and Healthy Aging. In the face of the COVID-19 pandemic that exposed the vulnerabilities of older populations, the launch of the Decade of Healthy Aging 2021-2030 and its baseline report and the 2018 Active Aging Index Analytical Report may constitute an opportunity to strategically think about the aging of the population as a national purpose in Portugal and in the other European countries that face similar challenges., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Costa, Câmara, Arriaga, Nogueira and Miguel.)

- Abstract
Background: Use of minimally invasive surgical techniques for lung resection surgery (LRS), such as video-assisted thoracoscopy (VATS), has increased in recent years. However, there is little information about the best anesthetic technique in this context. This surgical approach is associated with a lower intensity of postoperative pain, and its use has been proposed in programs for enhanced recovery after surgery (ERAS). This study compares the severity of postoperative complications in patients undergoing LRS who have received lidocaine intraoperatively either intravenously or via paravertebral administration versus saline., Methods/design: We will conduct a single-center randomized controlled trial involving 153 patients undergoing LRS through a thoracoscopic approach. The patients will be randomly assigned to one of the following study groups: intravenous lidocaine with more paravertebral thoracic (PVT) saline, PVT lidocaine with more intravenous saline, or intravenous remifentanil with more PVT saline. The primary outcome will be the comparison of the postoperative course through Clavien-Dindo classification. Furthermore, we will compare the perioperative pulmonary and systemic inflammatory response by monitoring biomarkers in the bronchoalveolar lavage fluid and blood, as well as postoperative analgesic consumption between the three groups of patients. We will use an ANOVA to compare quantitative variables and a chi-squared test to compare qualitative variables., Discussion: The development of less invasive surgical techniques means that anesthesiologists must adapt their perioperative management protocols and look for anesthetic techniques that provide good analgesic quality and allow rapid rehabilitation of the patient, as proposed in the ERAS protocols. The administration of a continuous infusion of intravenous lidocaine has proven to be useful and safe for the management of other types of surgery, as demonstrated in colorectal cancer. We want to know whether the continuous administration of lidocaine by a paravertebral route can be substituted with the intravenous administration of this local anesthetic in a safe and effective way while avoiding the risks inherent in the use of regional anesthetic techniques. In this way, this technique could be used in a safe and effective way in ERAS programs for pulmonary resection., Trial Registration: EudraCT, 2016-004271-52; ClinicalTrials.gov, NCT03905837 .

- Abstract
Introduction: Cardiovascular disease is an important cause of death and disability worldwide, and hypertension is responsible for at least 45% of all deaths due to heart disease and 51% of deaths due to stroke. This study aimed to estimate and describe the distribution of prevalence, awareness, treatment and control of hypertension in the Portuguese population in 2015., Methods: A national survey using a representative sample of 4911 individuals residing in Portugal and aged between 25 and 74 years was implemented. Trained nurses performed a health interview and a physical examination, including blood pressure measurement (right arm, three measurements at 1-min intervals). The prevalence of hypertension was stratified by gender, age group, marital status, education, occupation and type of residential area. Associations between hypertension prevalence and sociodemographic factors were assessed using bivariate and multivariate Poisson regression., Results: The overall hypertension prevalence was 36.0%. The highest rates were observed in males (39.6%), in individuals aged between 65 and 74 years (71.3%), and in those with low levels of education (62.6%) and with no formal occupation (64.5%). Among hypertensive individuals, 69.8% were aware of their condition and 69.4% were under treatment, of whom 71.3% were controlled. Rates of awareness and medical treatment were significantly higher among women and older individuals., Conclusions: A large majority of the adult Portuguese population are likely to reach blood pressure levels defined as hypertension in adulthood. Significant differences in hypertension prevalence were found according to gender, age and socioeconomic status, which highlights the importance of population strategies in public health policies., (Copyright © 2019 Sociedade Portuguesa de Cardiologia.

- Abstract
Background: Economic crises and unemployment have profound impact on mental health and well-being. Main goal of the Healthy Employment (HE) project is to enhance intersectoral actions promoting mental health among unemployed, namely through the implementation and effectiveness-evaluation of short-term and sustainable group interventions., Methods: The project follows a RE-AIM-based (Reach, Effectiveness, Adoption, Implementation and Maintenance) framework for assessing a cognitive-behavioural and psychoeducational intervention that has been developed for promoting mental health among unemployed people. It is a short-term group intervention (five sessions, four hours each, 20 unemployed persons per group) focused on mental health literacy, interpersonal communication and of emotional regulation. Implementation of the intervention will be carried out by clinical psychologists, following a standardized procedure manual. Effectiveness will be assessed through a randomized field study with two arms (intervention and control). Participants are unemployed people (18-65 years old, both genders, having at least nine years of formal education) registered at public employment centres from different geographical regions for less than 12 months (including first-job seekers). Allocation to arms of the study will follow a random match-to-case process, considering gender, age groups and educational level. Three moments of evaluation will occur: before intervention (baseline), immediately after its ending and three months later. Main outcomes are mental health literacy, mental health related personal and perceived stigma, psychological well-being, satisfaction with life and resilience. Intention-to-treat and per-protocol analyses will be conducted. Cohen's d coefficient and odds ratio will be used for assessing the size of the intervention effect, when significant., Discussion: Scientific and clinical knowledge will be applied to promote/protect psychological well-being of unemployed people. While the first phases of the project are funded by the European Economic Area Grants, long-term assessments of the intervention require a larger timeframe. Further funding and institutional support will be sought for this purpose. Already established intersectoral collaborations are key-assets to reach long-term sustainability of this project., Trial Registration: The study was registered with the Australian New Zealand Clinical Trials Registry; Prospectively registered number: ACTRN12616001432404 ; date of registration: 13 October 2016.

- Abstract
Background: The importance of economic evaluation in decision making is growing with increasing budgetary pressures on health systems. Diverse economic evidence is available for a range of interventions across national contexts within Europe, but little attention has been given to identifying evidence gaps that, if filled, could contribute to more efficient allocation of resources. One objective of the Research Agenda for Health Economic Evaluation project is to determine the most important methodological evidence gaps for the ten highest burden conditions in the European Union (EU), and to suggest ways of filling these gaps., Methods: The highest burden conditions in the EU by Disability Adjusted Life Years were determined using the Global Burden of Disease study. Clinical interventions were identified for each condition based on published guidelines, and economic evaluations indexed in MEDLINE were mapped to each intervention. A panel of public health and health economics experts discussed the evidence during a workshop and identified evidence gaps., Results: The literature analysis contributed to identifying cross-cutting methodological and technical issues, which were considered by the expert panel to derive methodological research priorities., Conclusions: The panel suggests a research agenda for health economics which incorporates the use of real-world evidence in the assessment of new and existing interventions; increased understanding of cost-effectiveness according to patient characteristics beyond the "-omics" approach to inform both investment and disinvestment decisions; methods for assessment of complex interventions; improved cross-talk between economic evaluations from health and other sectors; early health technology assessment; and standardized, transferable approaches to economic modeling.

- Abstract
In this work, Health Communication is considered as an important discipline in medicine and health sciences for his role as true determinant of health. We highlight their contribution to health promotion and disease prevention. Thus, the Health Communication Plan (PCS): Preventing the spread of Ebola virus disease in the Portuguese Speaking African Countries - KISS & KEYWORDS methodology is a tool that aims to minimize the risk of infection by Ebola virus in the Portuguese Speaking African Countries and also train for a general improvement of health conditions of the local populations. In the PCS design are especially considered the social and cultural contexts of the target populations, especially the customs, traditions and religion. Health Communication is considered as an Essential Function of Public Health and its main is to provide a population-based approach. The target of communication actions are population groups in addition to the individual communication, target-audiences are people without access to the media, in Guinea Bissau, Cape Verde and Sao Tome and Principe. Under the communication plan uses the methodology, models and practices both by media professionals as health. A proximity approach and cultural mediation, previously identified key facts, are defined objectives; outlines to the Plan in concrete and its implementation methodology (target-audience and following intervention, materials to be used and key-messages and partners to mobilize) following the World Health Organisation standards.

- Abstract
Background: In 2008, the Portuguese smoke-free law came into effect including partial bans in the leisure-hospitality (LH) sector. The objective of the study is to assess the prevalence of smoking control policies (total ban, smoking permission and designated smoking areas) adopted by the LH sector in Portugal. The levels of noncompliance with each policy are investigated as well as the main factors associated with smoking permission and noncompliance with the law., Methods: Cross-sectional study conducted between January 2010 and May 2011. A random sample of venues was selected from the Portuguese LH sector database, proportionally stratified according to type, size and geographical area. All venues were assessed in loco by an observer. The independent effects of venues' characteristics on smoking permission and the level of noncompliance with the law were explored using logistic regression., Results: Overall, 1.412 venues were included. Total ban policy was adopted by 75.9% of venues, while 8.4% had designated smoking areas. Smoking ban was more prevalent in restaurants (85.9%). Only 29.7% of discos/bars/pubs opted for complete ban. Full or partial smoking permission was higher in discos/bar/pubs (OR = 7.37; 95%CI 4.87 to 11.17). Noncompliance with the law was higher in venues allowing smoking and lower in places with complete ban (33.6% and 7.6% respectively, p<0.001). Discos/bars/pubs with full smoking permission had the highest level of noncompliance (OR = 3.31; 95%CI 1.40 to 7.83)., Conclusions: Our findings show a high adherence to smoking ban policy by the Portuguese LH sector. Nonetheless, one quarter of the venues is fully or partially permissive towards smoking, with the discos/bars/pubs considerably contributing to this situation. Venues with smoking permission policies were less compliant with the legislation. The implementation of a comprehensive smoke-free law, without any exceptions, is essential to effectively protect people from the second hand smoke.

- Abstract
The elderly population in Brazil has been growing apace, and this demographic transition has increasingly led to a situation where the elderly are dependent upon their relatives. However, the development of a training program could contribute to an improvement in the services provided by these caregivers, enhancing quality of life for the elderly. The aim of this study is to evaluate the effect of a Training Program for Informal Caregivers on the quality of life of elderly people with a deficit in self-care. Home visits were initially made to 15 elderly patients and the SF-36 questionnaire was applied. A multi-professional training program for the caregivers of these elderly people was then developed. The SF-36 questionnaire was again applied after 2 months of the training program to verify its effectiveness on the quality of life of the elderly people. On average a significant increase of scores related to "mental health" and a significant decrease in "limitations of physical aspects" was detected. The training of informal groups of caregivers by professionals from the healthcare area should be encouraged in order to promote awareness, exchange experiences and discuss the best inherent strategies for care.

- Abstract
Macrophage activation syndrome is a form of secondary haemophagocytic lymphohistiocytosis seen in the context of rheumatic diseases. It is seen most frequently in association with systemic onset juvenile arthritis or childhood Still's disease. Hemophagocytosis is part of a sepsis-like clinical syndrome caused by hypercytokinemia due to a highly stimulated but ineffective immune response. Coagulopathy and hemorrhages, decreased white cell count, elevated levels of aspartate aminotransferase, fever, rash, hepatosplenomegaly and central nervous system dysfunction are some of diagnostic criteria of macrophage activation syndrome, but it is very difficult to diagnose due to the lack of specific clinical signs. We report a 8-year-old child who was admitted to the ICU with lethargy, fever, acute respiratory failure, coagulopathy, metabolic acidosis and multiorgan failure. Septic shock was suspected, but he was diagnosed with macrophage activation syndrome and treated with corticosteroids and intravenous immunoglobulin and later discharged from the ICU., (Copyright © 2009 Asociación Española de Pediatría.

- Abstract
As a part of environmental health surveillance programs related to Portuguese solid waste incinerators (SWI), two biomonitoring projects have been established to investigate additional exposure to lead in children under the age of 6 years living in the vicinity of those facilities. The above-mentioned programs, being the only ones in the country that integrate systematic observations on human exposure to heavy metals, have to provide systematic data from Portuguese regions on the extent and pattern of human exposure to heavy metals, namely to lead. The present paper is the third of a series of papers prepared to accomplish that objective in regards to lead exposure as evaluated by measuring lead levels in children under the age of 6 years. Altogether, 250 children from Lisbon and 247 from Madeira Island have already been involved in the investigation. The present study evaluates spatial and temporal trends of lead exposure, based on comparisons of children's blood lead levels, either stratified by living area (exposed and control groups), or by time of exposure (T0, the baseline time, and T1, after approximately 2 years of regular operation of the facilities). The results obtained correspond to a relatively reduced number of individuals. Possibly for this reason, they are not fully conclusive in relation to whether living in the vicinity of SWI represents an additional risk of higher exposure to lead. Time trends of lead exposure as evaluated by blood lead levels in children also do not show any clear pattern. These conclusions and the fact that altogether around 3% of children from the whole group have blood lead levels >or=10 microg/dl warrant further investigation in order to clarify the contribution of incinerator emissions to the levels of lead in children and to identify alternative sources for preventive purposes, taking into consideration the relevance of even low lead exposure from a public health perspective, mainly in relation to children.

- Abstract
As part of environmental health surveillance programs related to solid waste incinerators located near Lisbon and on Madeira Island, human biomonitoring projects have been implemented in Portugal, some of them focused on cross-sectional surveys of heavy metals in blood. One of the general aims of these programs is to provide Portuguese data on the extent and pattern of human exposure to the pollutants potentially released in the stack gases from the incinerators, namely heavy metals. The present investigation reports information specifically on blood lead levels of newborn-mother pairs living in the vicinity of the incinerators under study, as well as of statistically similar participants living outside the exposed area. For Lisbon, lead levels determined at the baseline period (T0), as well as three subsequent evaluations of potential specific impacts of the incinerator (T1, T2 and T3) are described in order to investigate spatial and temporal trends of human exposure to lead. Available data for Madeira, namely lead levels in blood from the study population before the incinerator started operation, is also described. For Lisbon, analyses showed a statistically significant decrease of lead concentrations in maternal (p<0.001) and umbilical cord blood (p<0.001) during the whole monitoring period. Practically "overt" transplacental exposure to lead was observed only in the Lisbon biomonitoring project and for some cross-sectional surveys. Baseline levels for Madeira were the lowest found in all observations already performed in both programs (maternal and umbilical cord mean lead levels of 0.4 microg/dl and 0.3 microg/dl, respectively). No statistical associations have been found between lead levels in blood and age neither for global populations from Lisbon and Madeira nor for specific groups included in the different observational periods.

Human exposure to heavy metals makes it necessary to monitor these elements in the human body if the objective is to relate heavy metal exposure to adverse health effects. In Portugal, biomonitoring projects on heavy metals are being carried out on people living in the vicinity of solid waste incinerators. The projects are being developed in the ambit of two environmental health surveillance programs related to solid waste incineration facilities, one near Lisbon and the other on Madeira Island, that have the main objective of guaranteeing the safeguard of public health in relation to the potential negative impact of incineration processes on human health. These programs are the only ones in the country that integrate a systematic observation of human exposure to heavy metals as determined by the respective body burden in several population groups. Therefore, they are the only ones that are currently able to provide systematic data from Portuguese regions on the extent and pattern of human exposure to this type of pollutants. The present paper is the first of a series of three prepared papers with the objective of presenting and discussing available data. It addresses exposure to lead, cadmium and mercury as determined by their levels in blood of general population adults. Results suggest the effectiveness of source control measures in relation to both incinerators under study, similarly to what has been concluded from previous studies addressing exposure to dioxins. They also show, in relation to the baseline situation, a general significant trend for reduction of exposure to all studied heavy metals. Individuals from Lisbon seem to have a significantly higher body burden of the studied metals than those living in Madeira and, in general, metal exposure in men is significantly higher than in women, with the most relevant exception being the case of higher mercury levels in women, at the baseline and for both communities. Compared with published reference values for similar conditions, blood levels of cadmium, lead, and mercury of the present investigation seem to be relatively higher, in median terms and for extreme values, mainly in the case of cadmium and mercury. In the case of lead the differences are not so marked.

- Abstract
Biomonitoring of dioxin body burden, as evaluated by PCDD/F levels in blood, has been carried out in a total of 138 adults from general population living in the vicinity of solid waste incinerators in Portugal. Measurements were performed included in cross-sectional surveys within two Environmental Health Surveillance Programs launched in response to ecotoxicological concern in relation to solid waste incinerators near Lisbon and in Madeira Island. Overall conclusion from first published results is indicative that dioxin exposure of global populations cannot be related to the emissions of these facilities, meaning that dioxin sources control seems to be effective in relation to both incinerators. Main objective of present work was to investigate potential determinants of dioxin levels in the studied populations. Findings from this investigation also suggest that incineration does not impact on dioxin blood levels of nearby residents. Follow-up of a small group of individuals (22) from Lisbon gives preliminary indication on temporal control effectiveness of the Lisbon facility. Regarding comparison between PCDD/F levels from Lisbon and Madeira communities, individuals from Lisbon show higher median PCDD/F levels, likely to be better explained by more highly polluted areas in Lisbon than by eventual differences in dietary habits of the studied groups. In fact, analysis performed on the diet of both groups (not detailed in the present study) does not show a statistically significant difference in relation to any of the most relevant foodstuffs in the context of dioxin exposure. Comparison between Lisbon and Madeira in relation to pattern of the single congeners for PCDD/Fs shows a very similar profile. The highest contributions to the PCDD/Fs toxicity came from 12378-PCDD, 23478-PCDF, Hexa-CDD, 2378-TCDD and Hexa-CDF.

- Abstract
Objective: Because of concerns about the declining autopsy rate, an attempt was made to evaluate the contributions from the postmortem examination in children., Patients and Methods: We carried out a retrospective comparison analysis between clinical and pathological diagnosis of 56 consecutive autopsies performed on children who died in the PICU during the period 1983-1995., Results: The autopsy rate was 60%. Autopsy provided valuable clinical information in 50% of the cases. There were major diagnostic errors in three patients (5%), that if detected before death would probably have improved survival. Another 14 cases (25%) showed missed clinical diagnoses related to the basic illness and the cause of death, whose premortem diagnosis would not have prolonged survival. There were no diagnostic discrepancies in 28 cases (50%). The most unexpected findings revealed by the autopsies were iatrogenics (10 cases), metabolic diseases (4 cases), congenital immunodeficiency syndromes (4 cases) and pulmonary opportunistic infections (3 cases). Eight of these diseases were genetic. An age < 12 months or and ICU stay < 24 hours were not predicting factors of a higher incidence of major diagnostic errors., Conclusions: The value of the autopsy as quality assurance and to detect iatrogenics and occult genetic diseases is unquestionable. New strategies have to be designed to increase the rate of autopsies.

- Abstract
Objective: To describe the definitions for sepsis proposed by ACCP/SCCM Consensus Conference and to evaluate its capacity to classify children with severe meningococcal infection in homogeneous risk groups., Methods: Eighty children with acute meningococcal infection and severe sepsis or septic shock, admitted to the pediatric ICU during a ten years period were reviewed. Mean age: 38 months (1,3 mo-14 yrs)., Results: N. meningitidis was isolated in 84%. Sixty-four percent of the patients were bacteremic and 39% showed a positive culture in CSF. Overall mortality was 19%. Fifty-two patients (65%) were in severe sepsis on admission, fifteen of them (29%) developed shock, mortality for this group was 4%. Twenty-eight patients (35%) were in septic shock on admission, mortality was 44%. Overall mortality of the shock group was 35%, mortality of shock on admission was higher than mortality of shock postadmission (44% vs 13%, p = 0.0001). Major complications were: DIC (28%), ARDS (26%), purpura fulminans (21%). There were not major complications or deaths in patients who did not develop shock. Bacteremia was not significant associated with shock or death. Meningitis was more frequent in severe sepsis group but 62% of deaths got it. Univariant analysis showed significant differences between both groups relative to tissular perfusion variables, coagulation and meningeal involvement. Multivariate analysis allowed us to establish a predictive model of survival feasible on admission to the ICU. For its determination three parameters are used: blood pressure, platelets and base excess., Conclusion: Definitions proposed for severe sepsis and septic shock are a valuable tool to classify children with acute meningococcal infection in homogeneous risk groups.

- Abstract
This study compares the living situation, morbidity and mortality and related factors between two different communities, one in eastern Finland (with high mortality in cardiovascular diseases) and another in Lisbon, Portugal (representing the Mediterranean area with low ischaemic heart disease but nigh cerebrovascular mortality). The representative samples of 65-74 year old population were examined using the same study protocol, and official mortality statistics were analyzed from these countries. The results show that elderly Finns have more facilities at home than elderly Portuguese. Self reported diabetes mellitus, stroke and chronic bronchitis as well as obstipation, urinary problems, leg pain and chest pain, and cough in the morning were more prevalent in Portugal but cardiac failure was more common in Finland. Reported hypertension and antihypertensive drug treatment were equally prevalent in both countries, but diastolic blood pressure level was clearly higher in Portugal. Total CVD mortality in this age group is higher in Finland among men but lower among women, stroke mortality is higher but ischaemic heart disease lower among both genders in Portugal.
