Alterações da função visual e da qualidade de vida relacionada com a saúde em indivíduos idosos

RESUMO: Introdução: A visão é um sentido fundamental na relação do indivíduo com os mais variados ambientes, sendo elemento central na funcionalidade e independência do idoso, qualquer perturbação da função visual provoca limitações na qualidade de vida. As alterações demográficas em curso caracterizam-se pelo envelhecimento progressivo da população, paralelamente constata-se um aumento da prevalência de perturbações do sistema visual com alteração da função e do funcionamento visual. Considerando que os indivíduos idosos são mais dependentes da visão, e que não existem para esta área estudos desenvolvidos em Portugal, esta investigação tem como fundamento analisar a influência que a perturbação da função visual em indivíduos com 65 ou mais anos tem na qualidade de vida relacionada com a saúde. Estudaram-se também as características sócio-demográficas dos indivíduos participantes, da saúde visual e a percepção da saúde geral, bem como identificaram se junto dos idosos participantes e de Médicos especialistas em Medicina Geral e Familiar perspectivas sobre perturbações da função visual e envelhecimento. Desenho de estudo: Estudo transversal, caso-controlo e descritivo-exploratório. Materiais e Métodos: A partir de uma população de 112 indivíduos com 65 ou mais anos, frequentadores de várias instituições de apoio social do Concelho de Loures e de idosos frequentadores/institucionalizados da Mansão de Santa Maria de Marvila, unidade orgânica da Fundação D. Pedro IV, foram incluídos no estudo 90 (80,4%). Após consentimento informado, procedeu-se à avaliação da função visual nos Laboratórios de Ortóptica da Escola Superior de Tecnologia de Saúde de Lisboa, onde também se aplicaram o Questionário de Funcionamento Visual VFQ-25 e uma questão aberta para o tipo de dificuldades de visão sentidas durante o último ano. Aplicou-se ainda, em ambiente virtual, uma pergunta aberta a Médicos especialistas em Medicina Geral e Familiar para aspectos relacionados com o diagnóstico/suspeita relativamente tardio de perturbações da função visual. Procedeu-se ao tratamento descritivo das características sócio-demográficas, da percepção de saúde geral e da saúde visual e das respostas dos idosos e dos médicos. Analisou-se a relação entre função visual e qualidade de vida relacionada com a saúde aplicando o teste não-paramétrico de Mann-Whitney. Resultados: Constatou-se que os indivíduos da amostra são maioritariamente do género feminino (71,1%), casados (41,1%), detentores de baixos níveis de escolaridade em que 63,3% apenas frequentou/concluiu o 1º ciclo do ensino básico e quase na sua totalidade reformados (88,9%). Verifica-se que 77,8% dos idosos percepciona a sua saúde geral como razoável ou boa. Da mesma forma, 86,7% dos indivíduos têm a função visual alterada devido principalmente à alteração da acuidade visual para longe (86,7%), registando-se que 65,5% dos olhos tinham uma acuidade visual igual ou superior a 5/10. Outras dimensões que contribuíram para a alteração da função visual contam-se a sensibilidade ao contraste (63,3%), estereopsia (51,1%), visão cromática (38,9%) e a motilidade ocular (25,6%). Obtiveram-se assim maiores pontuações para as diversas escalas do questionário VFQ-25 em indivíduos com função visual alterada exceptuando nas escalas actividades de perto, condução e dependência. Verificou-se portanto existir relação entre alteração da função visual e perturbação da qualidade de vida relacionada com a saúde. À questão colocada aos idosos, 42,6% não manifestou qualquer razão para que visse mal/sentisse dificuldades de visão durante o último ano. A diminuição da acuidade visual para longe/perto foi referida por 20,5% dos indivíduos, seguido pela deterioração do estado de saúde geral e ocular por 15%. As respostas do Médicos especialistas em Medicina Geral e Familiar sobre razões para a suspeita/diagnóstico relativamente tardia das perturbações da função visual, indicam a iliteracia dos idosos para a saúde da visão e semiologia ocular (34%), a baixa formação/informação dos Médicos de Medicina Geral e Familiar na área da saúde da visão (22%) e a pouca acessibilidade e resposta demorada/ineficaz dos serviços de oftalmologia do SNS (20%) como principais motivos para os assuntos questionados.Conclusões: As alterações do sistema visual com impacto na função e no funcionamento visual alteram a qualidade de vida relacionada com a saúde, devido principalmente à alteração da acuidade visual para longe. Os idosos do estudo não valorizam a saúde visual ao percepcionarem positivamente a saúde geral e a saúde visual relativamente à avaliação da função visual. É fundamental definir estratégias e programas de literacia para a saúde da visão para toda a população, não apenas destinados a idosos. Sugere-se repensar o modelo de formação base dos Médicos com especial incidência na área da saúde da visão, com necessidades sentidas de formação/informação. As respostas obtidas dos idosos e dos Médicos indicaram existir fragilidades na saúde da visão, necessário repensar o modelo de prestação de cuidados de saúde nesta área. Esta investigação permitiu ao autor uma reflexão sobre as temáticas relacionadas com o envelhecimento levando a uma mudança de atitudes e comportamento na abordagem profissional a indivíduos idosos, promovendo autonomia nas escolhas e decisões em questões de saúde, na criação de estratégias para lidar com o problema de visão e na adaptação à nova condição de saúde da visão.---------------ABSTRACT:Purpose: The vision is a fundamental sense in the individual's relationship with the most varied environments, a central element in the functionality and independence of the elderly, any disturbance of visual function causes limitations in quality of life. The current demographic changes are characterized by progressive aging of population, there has been a parallel increase in the prevalence of disorders of the visual system by changing the visual function and functioning. Whereas the elderly are more dependent on vision, and there are no studies in this area developed in Portugal, this research is based analyze the influence that the disturbance of visual function in subjects aged 65 years or more has on the health related quality of life. We studied also the socio-demographic characteristics of the subjects, the eye health and general health perception, and identified themselves with the elderly participants and medical specialists in Family General Medicine perspective on disorders of visual function and aging. Design: Cross-sectional study, case control, descriptive and exploratory. Methods: From a population of 112 people with 65 or more years, regulars of various social welfare institutions of the Municipality of Loures and elderly regulars/institutionalized the Mansion of Santa Maria de Marvila, organic unity of the Foundation D. Pedro IV, were included 90 (80.4%). After informed consent, proceeded to the assessment of visual function in the Laboratories of Orthopticsof the School of Health Technology of Lisbon, where he also applied the Visual Functioning Questionnaire VFQ-25 and an open question for the type of vision difficulties experienced during the last year. Was applied also in a virtual environment, an open question to Doctors specialists in family general medicine related to the diagnosis/suspected relatively late disturbance of visual function. We carried out the descriptive treatment of socio-demographic characteristics, perception of general health and eye health and the responses of older people and doctors. We analyzed the relationship between visual function and quality of life related to health by applying the nonparametric Mann-Whitney test. Results: We found that individuals in the sample are mostly female (71.1%), married (41.1%), holders of low levels of education in which only 63.3% frequented / completed the 1st cycle of primary and almost entirely retired (88.9%). It is found that 77.8% of the elderly perceive their general health as fair or good. Likewise, 86.7% of individuals have altered vision mainly due to the change in visual acuity away (86.7%),up to 65.5% of eyes had a visual acuity of 5/10 or greater. Other dimensions that contributed to the alteration of visual function include contrast sensitivity (63.3%), stereopsis (51.1%), color vision (38.9%) and ocular motility (25.6%). There was thus obtained the highest scores for different scales of the questionnaire VFQ-25 in patients with altered vision except for scales related to near activities, driving and dependence. It is therefore a relationship between alteration in visual function and disturbance of quality of life related to health. To question for the elderly, 42.6% expressed no reason to see evil/feel difficulty seeing over the last year. The decrease in visual acuity for distance/near was reported by 20.5% of subjects, followed by the deterioration of general health and eye for 15%. The responses of medical specialists in general practice about reasons for the suspicion/diagnosis relatively late disturbance of visual function, indicate the illiteracy of the elderly for healthy vision and ocular semiology (34%), low education/information for Doctors in the health of vision (22%) and poor accessibility and response timeconsuming/ inefficient NHS ophthalmology services (20%) as main reasons for the subjects questioned. Conclusion: Changes in the visual system with an impact on visual function and the functioning change the health related quality of life, mainly due to the change in distance visual acuity. Older people do not value the visual health perceiving the general health and eye health positively relatively of visual function. It is essential to define strategies and literacy programs for eye health for the entire population, not just for the elderly. It is suggested reconsider the model of basic training of Doctors with special focus on the health of the vision, with special needs sensed training/information. The responses of older people and doctors have indicated there is weakness in eye health, need to rethink the model of health care in this area. This research allowed the author to reflect on issues related to aging leading to a change in attitudes and behavior in professional approach to the elderly, promoting autonomy in choices and decisions in health issues, creating strategies to deal with the problem of vision and adaptation to new conditions of eye health.

Playing With Fire: Decrease in Safe-Sex Attitudes Among Men Who Have Sex With Men in a Portuguese STI Clinic

Background: Sexually transmitted infections (STIs) present a major public health concern and a global cause of illness in both industrialized and developing countries. Portugal is no exception, with an increasing incidence of STIs, and one of the highest prevalences of HIV in Europe. Reduced risk perceptions among men who have sex with men (MSM) and a consequent high-risk sexual behaviour have been increasingly reported throughout the world. Objectives: To characterize the population of MSM attending a STI clinic in Lisbon, and to assess practice of condom use among these patients. Methods: Records of all MSM patients who attended the STI clinic from 2008 to 2011 were reviewed to study demographic characteristics, sexual behaviours, and leading diagnoses in this population. Results: Of a total of 389 patients, 108 MSM were identified (27.8%), mostly Portuguese men with high school or above education, aged 17 to 61 years (medium age of 32.4 years). More than half of the patients (52.8%) reported more than one sexual partner in the past 6 months (19.4% more than 5 partners), and only a third consistently used condom. A history of sex with sex workers was mentioned in 9.2%. The most prevalent diagnoses were syphilis (45.6%) and condylomata acuminata (38.9%). The prevalence of HIV infection in this subgroup of patients was significantly higher than in the rest of the population (47.2% vs. 14.9%). Inconsistent condom use increased over the years (36.4% in 2008, 66.7% in 2011), and these patients revealed a greater number of sexual partners than condom users (60.4% vs. 50%). However, 38.9% of condom users presented with early syphilis, suggesting inadequate use of this barrier method. Among HIV patients, almost half of them (49%) had sex with more than one partner in the previous six months, and 47.1% did not use the condom during all sexual practices. Of these, 45.8% were not on antiretroviral therapy. Conclusions: High-risk sexual behaviours (inconsistent use of condom and multiple partners) are increasingly prevalent in this MSM subpopulation, despite previous educational programmes. The high incidence of risk behaviours among HIV infected patients is particularly worrisome, and must be addressed with innovative interventions and population-based prevention strategies.

Case Report of Malignant Endometrial Polyps

The aims of this retrospective review were to determine the frequency of malignant endometrial polyps diagnosed with ambulatory hysteroscopy in the Obstetrics/Gynaecology Department of HDE, Lisbon, between January 2001 and December 2005 and to characterize these cases according to risk factors, sonographic and endoscopic findings tumoral histology, and tumor stage.We found seven cases of malignant endometrial polyps in a total of 1333 polyps initially diagnosed: an incidence rate of 0. 53%. These seven patients had a mean age of 68 years (55–82 years), and all were postmenopausal, with five having one risk factor each for endometrial cancer. Metrorrhagia was present in six of the seven patients(85.7%). Ultrasonography was abnormal in all seven patients, with a mean endometrial thickness of 26 mm(range: 12–44 mm). The hysteroscopy images suggested malignancy in all cases. All except one patient had a single polyp. The polyps had volumes between 1.5 and 3 cm; two were removed completely and five were biopsed. The histological subtype was: mixed endometrioid/serous papillary or clear cell (2), adenocarcinoma with squamous differentiation (2), carcinosarcoma (2), and clear cell carcinoma (1). Malignancy inside polyps is rare, but diagnostic hysteroscopy with visual guided biopsies can identify these cases in the earlier stages. The risk factors are not different from those of other endometrial carcinomas, but the histological subtype seems to point to more aggressive cancers.

CO2 Concentration in Day Care Centres is Related to Wheezing in Attending Children

Poor ventilation at day care centres (DCCs) was already reported, although its effects on attending children are not clear. This study aimed to evaluate the association between wheezing in children and indoor CO2 (a ventilation surrogate marker) in DCC and to identify behaviours and building characteristics potentially related to CO2. In phase I, 45 DCCs from Lisbon and Oporto (Portugal) were selected through a proportional stratified random sampling. In phase II, 3 months later, 19 DCCs were further reassessed after cluster analysis for the greatest difference comparison. In both phases, children’s respiratory health was assessed by ISAAC-derived questionnaires. Indoor CO2 concentrations and building characteristics of the DCC were evaluated in both phases, using complementary methods. Mixed effect models were used to analyze the data. In phase I, which included 3,186 children (mean age 3.1±1.5 years), indoor CO2 concentration in the DCC rooms was associated with reported wheezing in the past 12months (27.5 %) (adjusted odds ratio (OR) for each increase of 200 ppm 1.04, 95 % CI 1:01 to 1:07). In phase II, the association in the subsample of 1,196 children seen in 19 out of the initial 45 DCCs was not significant (adjusted OR 1.02, 95 % CI 0.96 to 1.08). Indoor CO2 concentration was inversely associated with the practices of opening Windows and internal doors and with higher wind velocity. A positive trend was observed between CO2 and prevalence of reported asthma (4.7 %). Conclusion: Improved ventilation is needed to achieve a healthier indoor environment in DCC.

Transplante hepático sequencial com preservação da veia cava inferior (técnica de "Duplo Piggyback") : uma técnica original

RESUMO:Desde a declaração de Bethesda em 1983, a transplantação hepática é considerada um processo válido e aceite na prática clínica para muitos doentes com doença hepática terminal, relativamente aos quais não houvesse outra alternativa terapêutica. Em 1991, por proposta de Holmgren, professor de genética, o cirurgião sueco Bo Ericzon realizou em Huntingdon (Estocolmo) o primeiro transplante hepático num doente PAF (Polineuropatia Amilloidótica Familiar), esperando que a substituição do fígado pudesse frenar a evolução da doença. Nesta doença hereditária autossómica dominante, o fígado, apesar de estrutural e funcionalmente normal, produz uma proteína anormal (TTR Met30) responsável pela doença. A partir de então, a transplantação hepática passou a ser a única terapêutica eficaz para estes doentes. Portugal é o país do mundo com mais doentes PAF, tendo sido o médico neurologista português Corino de Andrade quem, em 1951, identificou e descreveu este tipo particular de polineuropatia hereditária, também conhecida por doença de Andrade. Com o início da transplantação hepática programada em Setembro de 1992, o primeiro doente transplantado hepático em Portugal, no Hospital Curry Cabral, foi um doente PAF. Desde logo se percebeu que a competição nas listas de espera em Portugal, entre doentes hepáticos crónicos e doentes PAF viria a ser um problema clínico e ético difícil de compatibilizar. Em 1995, Linhares Furtado, em Coimbra, realizou o primeiro transplante dum fígado dum doente PAF num doente com doença hepática metastática, ficando este tipo de transplante conhecido como transplante sequencial ou “em dominó”. Fê-lo no pressuposto de que o fígado PAF, funcional e estruturalmente normal, apesar de produzir a proteína mutada causadora da doença neurológica, pudesse garantir ao receptor um período razoável de vida livre de sintomas, tal como acontece na história natural desta doença congénita, cujas manifestações clínicas apenas se observam na idade adulta. A técnica cirúrgica mais adequada para transplantar o doente PAF é a técnica de “piggyback”, na qual a hepatectomia é feita mantendo a veia cava do doente, podendo o transplante ser feito sem recorrer a bypass extracorporal. Antes de 2001, para fazerem o transplante sequencial, os diferentes centros alteraram a técnica de hepatectomia no doente PAF, ressecando a cava com o fígado conforme a técnica clássica, recorrendo ao bypass extracorporal. No nosso centro imaginámos e concebemos uma técnica original, com recurso a enxertos venosos, que permitisse ao doente PAF submeter-se à mesma técnica de hepatectomia no transplante, quer ele viesse a ser ou não dador. Essa técnica, por nós utilizada pela primeira vez a nível mundial em 2001, ficou conhecida por Transplante Sequencial em Duplo Piggyback. Este trabalho teve como objectivo procurar saber se a técnica por nós imaginada, concebida e utilizada era reprodutível, se não prejudicava o doente PAF dador e se oferecia ao receptor hepático as mesmas garantias do fígado de cadáver. A nossa série de transplantes realizados em doentes PAF é a maior a nível mundial, assim como o é o número de transplantes sequenciais de fígado. Recorrendo à nossa base de dados desde Setembro de 1992 até Novembro de 2008 procedeu-se à verificação das hipóteses anteriormente enunciadas. Com base na experiência por nós introduzida, a técnica foi reproduzida com êxito em vários centros internacionais de referência, que por si provaram a sua reprodutibilidade. Este sucesso encontra-se publicado por diversos grupos de transplantação hepática a nível mundial. Observámos na nossa série que a sobrevivência dos doentes PAF que foram dadores é ligeiramente superior àqueles que o não foram, embora sem atingir significância estatística. Contudo, quando se analisaram, apenas, estes doentes após a introdução do transplante sequencial no nosso centro, observa-se que existe uma melhor sobrevida nos doentes PAF dadores (sobrevida aos 5 anos de 87% versus 71%, p=0,047).Relativamente aos receptores observámos que existe um benefício a curto prazo em termos de morbi-mortalidade (menor hemorragia peri-operatória) e a longo prazo alguns grupos de doentes apresentaram diferenças de sobrevida, embora sem atingir significância estatística, facto este que pode estar relacionado com a dimensão das amostras parcelares analisadas. Estes grupos são os doentes com cirrose a vírus da hepatite C e os doentes com doença hepática maligna primitiva dentro dos critérios de Milão. Fora do âmbito deste trabalho ficou um aspecto relevante que é a recidiva da doença PAF nos receptores de fígado sequencial e o seu impacto no longo prazo. Em conclusão, o presente trabalho permite afirmar que a técnica por nós introduzida pela primeira vez a nível mundial é exequível e reprodutível e é segura para os doentes dadores de fígado PAF, que não vêem a sua técnica cirúrgica alterada pelo facto de o serem. Os receptores não são, por sua vez, prejudicados por receberem um fígado PAF, havendo mesmo benefícios no pós-operatório imediato e, eventualmente, alguns grupos específicos de doentes podem mesmo ser beneficiados.---------ABSTRACT: Ever since Bethesda statement in 1983, Liver Transplantation has been accepted as a clinical therapeutic procedure for many patients with advanced hepatic failure Holmgren, professor of genetics, suggested that one could expect that transplanting a new liver could lead to improve progressive neurological symptoms of Familial Amyloidotic Polyneuropathy (PAF). Bo Ericzon, the transplant surgeon at Huddinge Hospital in Stockholm, Sweden, did in 1991 the first Liver Transplant on a FAP patient. FAP is an inherited autosomal dominant neurologic disease in which the liver, otherwise structural an functionally normal, produces more than 90% of an abnormal protein (TTR Met30) whose deposits are responsible for symptoms. Liver Transplantation is currently the only efficient therapy available for FAP patients. Portugal is the country in the world where FAP is most prevalent. The Portuguese neurologist Corino de Andrade was the first to recognize in 1951 this particular form of inherited polyneuropathy, which is also known by the name of Andrade disease. Liver Transplantation started as a program in Portugal in September 1992. The first patient transplanted in Lisbon, Hospital Curry Cabral, was a FAP patient. From the beginning we did realize that competition among waiting lists of FAP and Hepatic patients would come to be a complex problem we had to deal with, on clinical and ethical grounds. There was one possible way-out. FAP livers could be of some utility themselves as liver grafts. Anatomically and functionally normal, except for the inherited abnormal trace, those livers could possibly be transplanted in selected hepatic patients. Nevertheless the FAP liver carried with it the ability to produce the mutant TTR protein. One could expect, considering the natural history of the disease that several decades would lapse before the recipient could suffer symptomatic neurologic disease, if at all. In Coimbra, Portugal, Linhares Furtado performed in 1995 the first transplant of a FAP liver to a patient with metastatic malignant disease, as a sequential or “domino” transplant. FAP Liver Transplant patients, because of some dysautonomic labiality and unexpected reactions when they are subjected to surgery, take special advantage when piggyback technique is used for hepatectomy. This technique leaves the vena cava of the patient undisturbed, so that return of blood to the heart is affected minimally, so that veno-venous extracorporeal bypass will not be necessary. The advantages of piggyback technique could not be afforded to FAP patients who became donors for sequential liver transplantation, before we did introduce our liver reconstruction technique in 2001. The hepatectomy took the vena cava together with the liver, which is the classical technique, and the use of extracorporeal veno-venous bypass was of necessity in most cases. The reconstruction technique we developed in our center and used for the first time in the world in 2001 consists in applying venous grafts to the supra-hepatic ostia of piggyback resected FAP livers so that the organ could be grafted to a hepatic patient whose liver was itself resected with preservation of the vena cava. This is the double piggyback sequential transplant of the liver. It is the objective of this thesis to evaluate the results of this technique that we did introduce, first of all that it is reliable and reproducible, secondly that the FAP donor is not subjected to any additional harm during the procedure, and finally that the recipient has the same prospects of a successful transplant as if the liver was collected from a cadaver donor. Our series of liver transplantation on FAP patients and sequential liver transplants represent both the largest experience in the world. To achieve the analysis of the questions mentioned above, we did refer to our data-base from September 1992 to November 2008. The reconstructive technique that we did introduce is feasible: it could be done with success in every case ion our series. It is also reproducible. It has been adopted by many international centers of reference that did mention it in their own publications. We do refer to our data-base in what concerns the safety for the FAP donor.Five years survival of FAP transplanted patients that have been donors (n=190) has been slightly superior to those who were not (n=77), with no statistical significance. However, if we consider five year survival of FAP transplanted patients after the beginning of sequential transplant program in our center, survival is better among those patients whose liver was used as a transplant (87% survival versus 71%, p=0.047). In what concerns recipients of FAP livers: Some short-term benefit of less perioperative morbi-mortality mainly less hemorrhage. In some groups of particular pathologies, there is a strong suggestion of better survival, however the scarcity of numbers make the differences not statistically significant. Patients with cirrhosis HVC (83% versus73%) and patients with primitive hepatic cancer within Milan criteria (survival of 70% versus 58%) are good examples. There is one relevant problem we left beyond discussion in the present work: this is the long-term impact of possible recurrence of FAP symptoms among recipients of sequential transplants. In Conclusion: The reconstruction technique that we did develop and introduce is consistently workable and reproducible. It is safe for FAP donors with the advantage that removal of vena cava can be avoided. Hepatic patients transplanted with those livers suffer no disadvantages and have the benefit of less hemorrhage. There is also a suggestion that survival could be better in cirrhosis HVC and primary liver cancer patients.

The Role of Psychological Adjustment in the Decision-Making Process for Voluntary Termination of Pregnancy

BACKGROUND: This study's objective was to evaluate the role of psychological adjustment in the decision-making process to have an abortion and explore individual variables that might influence this decision. METHODS: In this cross-sectional study, we sequentially enrolled 150 women who made the decision to voluntarily terminate a pregnancy in Maternity Dr. Alfredo da Costa, in Lisbon, Portugal, between September 2008 and June 2009. The instruments were the Depression, Anxiety and Stress Scale (DASS), Satisfaction with Social Support Scale (SSSS), Emotional Assessment Scale (EAS), Decision Conflict Scale (DCS), and Beliefs and Values Questionnaire (BVQ). We analyzed the data using Student's T-tests, MANOVA, ANOVA, Tukey's post-hoc tests and CATPCA. Statistically significant effects were accepted for p<0.05. RESULTS: The participants found the decision difficult and emotionally demanding, although they also identified it as a low conflict decision. The prevailing emotions were sadness, fear and stress; but despite these feelings, the participants remained psychologically adjusted in the moment they decided to have an abortion. The resolution to terminate the pregnancy was essentially shared with supportive people and it was mostly motivated by socio-economic issues. The different beliefs and values found in this sample, and their possible associations are discussed. CONCLUSION: Despite high levels of stress, the women were psychologically adjusted at the time of making the decision to terminate the pregnancy. However, opposing what has been previously reported, the women presented high levels of sadness and fear, showing that this decision was hard to make, triggering disruptive emotions.

Environment and Health in Children Day Care Centres (ENVIRH) - Study Rationale and Protocol

Background: Indoor air quality (IAQ) is considered an important determinant of human health. The association between exposure to volatile organic compounds, particulate matter, house dust mite, molds and bacteria in day care centers (DCC) is not completely clear. The aim of this project was to study these effects. Methods --- study design: This study comprised two phases. Phase I included an evaluation of 45 DCCs (25 from Lisbon and 20 from Oporto, targeting 5161 children). In this phase, building characteristics, indoor CO2 and air temperature/relative humidity, were assessed. A children’s respiratory health questionnaire derived from the ISAAC (International Study on Asthma and Allergies in Children) was also distributed. Phase II encompassed two evaluations and included 20 DCCs selected from phase I after a cluster analysis (11 from Lisbon and 9 from Oporto, targeting 2287 children). In this phase, data on ventilation, IAQ, thermal comfort parameters, respiratory and allergic health, airway inflammation biomarkers, respiratory virus infection patterns and parental and child stress were collected. Results: In Phase I, building characteristics, occupant behavior and ventilation surrogates were collected from all DCCs. The response rate of the questionnaire was 61.7% (3186 children). Phase II included 1221 children. Association results between DCC characteristics, IAQ and health outcomes will be provided in order to support recommendations on IAQ and children’s health. A building ventilation model will also be developed. Discussion: This paper outlines methods that might be implemented by other investigators conducting studies on the association between respiratory health and indoor air quality at DCC.

The Impact of Multifocal Intraocular Lens in Retinal Imaging with Optical Coherence Tomography

Multifocal intraocular lenses (MF IOLs) have concentric optical zones with different dioptric power, enabling patients to have good visual acuity at multiple focal points. However, several optical limitations have been attributed to this particular design. The purpose of this study is to access the effect of MF IOLs design on the accuracy of retinal optical coherence tomography (OCT). Cross-sectional study conducted at the Refractive Surgery Department of Central Lisbon Hospital Center. Twenty-three eyes of 15 patients with a diffractive MF IOL and 27 eyes of 15 patients with an aspheric monofocal IOL were included in this study. All patients underwent OCT macular scans using Heidelberg Spectralis®. Macular thickness and volume values and image quality (Q factor) were compared between the two groups. There were no statistically significant differences between both groups regarding macular thickness or volume measurements. Retinal OCT image quality was significantly lower in the MF IOL group (p < 0.01). MF IOLs are associated with a significant decrease in OCT image quality. However, this fact does not seem to compromise the accuracy of spectral domain OCT retinal measurements.

Promoção da saúde mental em espaço urbano

RESUMO: A saúde pública deve estar atenta aos contextos e às mudanças sociais, políticas, económicas, científicas e tecnológicas com que se confrontam constantemente as comunidades, particularmente em situações de grandes transformações como o momento que a União Europeia atravessa. A urbanização é provavelmente a mudança demográfica mais importante das últimas décadas. Tendo importantes repercussões sobre a saúde mental, é importante desenvolver a investigação neste domínio, de forma multidisciplinar e integrando a compreensão dos diferentes determinantes sociais, psicológicos e físicos. As políticas de saúde mental tornaram-se uma parte importante da política social e da sociedade de bem-estar, em particular se considerarmos a urbanização das nossas comunidades. Considerar a saúde mental em espaço urbano é fundamentalmente estudar como um espaço particular pode influenciar a saúde. Baseado nesta reflexão, desenvolveu-se uma investigação participada de base comunitária, com recurso a uma metodologia de estudo de caso. Recorreu-se a dezenas de documentos de referência local, registos em arquivo, à observação direta, à observação participante e à observação in loco do espaço urbano. Foi utilizada uma amostragem em bola de neve, estratificada, para selecionar 697 habitantes de uma cidade da área metropolitana de Lisboa. Estes habitantes foram entrevistados por 42 entrevistadores, previamente formados, assim como foram enviados questionários online dirigidos aos professores (196) e aos Técnicos Superiores de Serviço Social (12) em exercício no espaço urbano em estudo, para a caraterização sociodemográfica e para avaliação de indicadores de saúde, de indicadores relacionados com a saúde e de indicadores estruturais de saúde mental. Os resultados mostraram um espaço urbano promotor de saúde estrutura-se para capacitar os seus cidadãos a se integrarem ativamente no funcionamento da sua comunidade. Foram identificadas algumas caraterísticas como 1) o início do processo de promoção da saúde mental ser o mais precoce possível; 2) a participação comunitária ativa, num sentimento de segurança individual e comunitária, envolvendo estruturas governamentais e não-governamentais; 3) a solidariedade e a inclusão, promovendo o voluntariado e a promoção do suporte social e desenvolvendo a coesão social; 4) o reconhecimento das necessidades expressas pelos habitantes; 5) a identificação de respostas para a conciliação entre vida pessoal, familiar e profissional; 6) as estruturas de acompanhamento dos grupos sociais mais desfavorecidos; 7) as estratégias de combate ao isolamento envolvendo a população sénior e outros grupos minoritários ativamente no processo de reorganização do seu funcionamento social; 8) uma efetiva governança e gestão relacional por parte dos poderes locais, centrando a vida quotidiana da comunidade nas pessoas. A investigação participada de base comunitária constitui um instrumento útil e eficaz no desenho de planos locais de promoção da saúde mental para encontrar respostas ao desafio em saúde pública: a saúde mental e a urbanização.

Perinatal Ischemic Stroke: a Five-Year Retrospective Study in a Level-III Maternity

Objective To study the incidence, clinical presentation, risk factors, imaging diagnosis, and clinical outcome of perinatal stroke. Methods Data was retrospectively collected from full-term newborns admitted to the neonatal unit of a level III maternity in Lisbon with cerebral stroke, from January 2007 to December 2011. Results There were 11 cases of stroke: nine were arterial ischemic stroke and two were cerebral venous sinus thrombosis. We estimated an incidence of arterial ischemic stroke of 1.6/5,000 births and of cerebral venous sinus thrombosis of 7.2/100,000 births. There were two cases of recurrent stroke. Eight patients presented with symptoms while the remaining three were asymptomatic and incidentally diagnosed. The most frequently registered symptoms (8/11) were seizures; in that, generalized clonic (3/8) and focal clonic (5/8). Strokes were more commonly left-sided (9/11), and the most affected artery was the left middle cerebral artery (8/11). Transfontanelle ultrasound was positive in most of the patients (10/11), and stroke was confirmed by cerebral magnetic resonance in all patients. Electroencephalographic recordings were carried out in five patients and were abnormal in three (focal abnormalities n=2, burst-suppression pattern n=1). Eight patients had previously identified risk factors for neonatal stroke which included obstetric and neonatal causes. Ten patients were followed up at outpatients setting; four patients developed motor deficits and one presented with epilepsy. Conclusions Although a modest and heterogeneous sample, this study emphasizes the need for a high level of suspicion when it comes to neonatal stroke, primarily in the presence of risk factors. The prevalence of neurological sequelae in our series supports the need of long-term follow-up and early intervention strategies.

Compliance with ESPGHAN Position on Complementary Feeding in a Multicultural European Community. Does Ethnicity Matter?

Introduction: In 2008, ESPGHAN published a position paper on complementary feeding providing recommendations to health care professionals. Cultural and socio-economic factors might affect the compliance to these orientations. Aim: To estimate the prevalence of inadequacies during complementary feeding (ESPGHAN, 2008) and its association with different ethnic backgrounds. Methods: Cross-sectional survey of a convenience sample of caretakers of children up to 24 months of age in a single community health centre in Greater Lisbon, through a volunteer, self-applied questionnaire. Results: From a sample of children with wide cultural diversity, 161 valid questionnaires were obtained (median child’s age 9 months, median mother’s age 32 years). The prevalence rate of at least one complementary feeding inadequacy was 46% (95%CI: 38.45-53.66). The commonest inadequacies were: avoiding lumpy solid foods after 10 months of age (66.7%), avoidance or delayed introduction of foods beyond 12 months (35.4%), introduction of gluten beyond 7 months (15.9%) or salt before 12 months (6.7%). For each increase of 1 month in the age of the child, the odds of inadequacies raised 36.7% (OR = 1.37; 95%CI: 1.20-1.56; p < 0.001). The odds for inadequacies in children of African or Brazilian offspring was three times higher that of Portuguese ancestry (OR = 3.31; 95%CI: 0.87-12.61; p = 0.079). The influence of grandparents was related to an increase in the odds of inadequacies (OR = 3.69; 95%CI: 0.96-14.18; p = 0.058).Conclusion: Inadequacies during complementary feeding are frequent and may be influenced by the cultural background.
