Adesão ao tratamento em pacientes com depressão major: A influência da percepção de doença, suporte social, espiritualidade e do estado emocional

Este estudo teve como finalidade investigar a relação entre alguns factores psicossociais e a adesão terapêutica, utilizando como variáveis preditoras, as representações de doença, a ansiedade e depressão as previsões de suporte social, e a espiritualidade e como variáveis de resultado, a adesão ao regime terapêutico, através da avaliação da adesão à medicação. Pretendeu-se testar quatro hipóteses: (1) Prevê-se que as representações de depressão nas suas dimensões da consequências, duração e controlo pessoal e de tratamento, identidade, preocupação, emoções e compreensão da doença sejam preditores significativos da adesão ao tratamento medicamentoso; (2) Prevê-se que os níveis de ansiedade e depressão dos doentes depressivos estarão significativa e negativamente correlacionados com os níveis de adesão ao tratamento medicamentoso; (3) Prevê-se que os níveis de suporte social percebido estarão significativa e positivamente correlacionados com os níveis de adesão ao tratamento medicamentoso e (4) Prevê-se que os níveis de espiritualidade se encontrem significativa e positivamente correlacionados com os níveis de adesão ao tratamento medicamentoso. Tratou-se de um estudo transversal, com desenho correlacionai e foi desenvolvido num Hospital da Região do Alentejo, mais especificamente, num Departamento de Psiquiatria a saúde Mental, com uma amostra não aleatória de 15 pacientes com o diagnóstico de Depressão. Os resultados confirmaram parcialmente a primeira hipótese, sendo as representações de doença, nas suas dimensões controlo pessoal, controlo do tratamento e emoções preditores significativos da adesão (mais especificamente das alterações das doses da medicação). A segunda hipótese também foi confirmada parcialmente, sendo a depressão preditora da adesão (tanto na dimensão do esquecimento, quanto na alteração das doses da medicação). A terceira hipótese foi, também, parcialmente confirmada sendo a aliança fiável preditora significativa da adesão (na dimensão do esquecimento da toma da medicação). Por último, a quarta hipótese foi igualmente confirmada parcialmente sendo a esperança/optimismo preditora significativa da adesão (tanto na dimensão do esquecimento, quanto na alteração das doses da medicação). Nas análises exploratórias verificou-se a influência da variável sócio­ demográfico “sexo” nas representações cognitivas e também na depressão. A "idade" também demonstrou algum efeito nas alterações à medicação e nas provisões sociais. O "estado civil" mostrou efeito no aconselhamento e na oportunidade de prestação de valores. As variáveis clínicas também mostraram ter influência. O "tempo de doença" mostrou efeito significativo nas representações emocionais, nas crenças, esperança/optimismo e no esquecimento da medicação. A "duração do tratamento com medicação" mostrou efeito na compreensão da doença e no esquecimento da medicação. Por fim, são apresentadas algumas implicações da depressão, bem como algumas sugestões para estudos futuros. /ABSTRACT: This study aimed to investigate the relationship between some psychosocial factors and the adherence, using as predictor variables, the representations of illness, the anxiety and depression, the social support predictions, and spirituality, and as outcome variables, adherence to treatment regimen, through the assessment of medication adherence. lt was intended to test four hypotheses: (1) lt is expected that the depression representations in its dimensions of consequences, duration and personal control and treatment, identity, concern, emotions and disease understanding are significant predictors of adherence to therapy; (2) lt is expected that anxiety and depression levels in depressed patients are significantly and negatively correlated with the levels of adherence to therapy; (3) lt is expected that the levels of perceived social support are significantly and positively correlated with the levels of adherence to drug treatment and (4) lt is expected that the levels of spirituality are significantly and positively correlated with levels of adherence to therapy. This was a cross-sectional study with correlational design and was developed in one Hospital of the Alentejo Region, more specifically, in a Department of Psychiatry and Mental Health, with a non¬random sample of 15 patients diagnosed with depression. The results partially confirmed the first hypothesis, being the representations of disease, in its dimensions of personal control, treatment control and emotions, significant predictors of adherence (more specifically, of the changes in the doses of medication). The second hypothesis was also partially confirmed, with depression being a predictor of adherence {both in the extent of oblivion and in the changes of medication doses). The third hypothesis was also partially confirmed, being the trustable alliance a quite significantly reliable predictor of adherence {in the dimension of the medication oblivion). Finally, the fourth hypothesis was equally partially confirmed, being the hope/optimism significant predictor of adherence (both in the extent of oblivion and in changing doses of medication). ln exploratory analyzes, it was verified the influence of socio-demographic variable "sex" in the cognitive representations and also in depression. The "age" also had some effect on changes to medication and social provisions. The "marital status" had effect in the counseling and in the opportunity to provide values. The clinical variables also proved to have influence. "Time sickness" had a significant effect on emotional representations, beliefs, hope/optimism and medication oblivion. The "treatment duration with medication" had effect in the disease understanding and the medication oblivion. Finally, are presented some implications of depression as well as some suggestions for future studies.

Medicina de espécies zoológicas

O presente relatório refere-se ao estágio curricular realizado no Badoca Safari Park, no âmbito do mestrado integrado em medicina veterinária da Universidade de Évora, na área de medicina de espécies zoológicas Este encontra-se dividido em duas partes, uma relativa às atividades realizadas e casuística, acompanhada de aprofundamento teórico, e outra relacionada com a pesquisa de hemoparasitas em ungulados, através de esfregaços sanguíneos, efetuada no decorrer do estágio. As hemoparasitoses são infeções com potencial zoonótico, transmitidas por vetores, associadas a importantes perdas económicas. O controlo destas afeções tem como obstáculos fatores económicos e sociais, a heterogenicidade de hospedeiros que estes hemoparasitas e respetivos vetores apresentam, assim como o facto das espécies de animais selvagens poderem atuar como hospedeiros reservatórios. A entrada de animais exóticos e saída de autóctones, em zonas endémicas, provoca desequilíbrios na relação entre o parasita e hospedeiro que poderão despoletar episódios de doença; Abstract: Zoo and Wildlife medicine This report refers to the internship held at Badoca Safari Park, as part of the integrated master’s degree in veterinary medicine, at the University of Évora, in the clinic area of wild species and wild animals. This thesis is devided into two parts, one on the activities and cases, accompanied by theoretical studies, and the other related to hemoparasites research on ungulates through blood smears, performed during the intership. The hemoparasitoses are infections with zoonotic potential, transmited by vectors associated with significant economic losses. The control of these affections has as main obstacles the economic and social factors, the heterogeneity of hosts these hemoparasites and respective vectors present, as well as the fact that the wildlife species can act as reservoir hosts. The entry of exotic animals and the disappearance of natives, in endemic areas, causes imbalances in the relationship between parasite and host that can trigger episodes of illness.

Cost-effectiveness of Sick Leave Policies for Health Care Workers with Influenza-like Illness, Brazil, 2009

We describe the effect of influenza-like illness (ILI) during the outbreak of pandemic (H1N1) 2009 on health care worker (HCW) absenteeism and compare the effectiveness and cost of 2 sick leave policies for HCWs with suspected influenza. We assessed initial 2-day sick leaves plus reassessment until the HOW was asymptomatic (2-day + reassessment policy), and initial 7-day sick leaves (7-day policy). Sick leaves peaked in August 2009: 3% of the workforce received leave for ILI. Costs during May October reached R$798,051.87 (approximate to US $443,362). The 7-day policy led to a higher monthly rate of sick leave days per 100 HCWs than did the 2-day + reassessment policy (8.72 vs. 3.47 days/100 HCWs; p<0.0001) and resulted in higher costs (US $609 vs. US $1,128 per HCW on leave). ILI affected HCW absenteeism. The 7-day policy was more costly and not more effective in preventing transmission to patients than the 2-day + reassessment policy.

Monitoring stress tolerance and occurrences of upper respiratory illness in basketball players by means of psychometric tools and salivary biomarkers

The aim of the study was to evaluate the possible relationships between stress tolerance, training load, banal infections and salivary parameters during 4 weeks of regular training in fifteen basketball players. The Daily Analysis of Life Demands for Athletes` questionnaire (sources and symptoms of stress) and the Wisconsin Upper Respiratory Symptom Survey were used on a weekly basis. Salivary cortisol and salivary immunoglobulin A (SIgA) were collected at the beginning (before) and after the study, and measured by enzyme-linked immunosorbent assay (ELISA). Ratings of perceived exertion (training load) were also obtained. The results from ANOVA with repeated measures showed greater training loads, number of upper respiratory tract infection episodes and negative sensation to both symptoms and sources of stress, at week 2 (p < 0.05). Significant increases in cortisol levels and decreases in SIgA secretion rate were noted (before to after). Negative sensations to symptoms of stress at week 4 were inversely and significantly correlated with SIgA secretion rate. A positive and significant relationship between sources and symptoms of stress at week 4 and cortisol levels were verified. In summary, an approach incorporating in conjunction psychometric tools and salivary biomarkers could be an efficient means of monitoring reaction to stress in sport.

Presentations of physical illness in people with developmental disability: the example of gastro-oesophageal reflux

People with developmental disabilities are becoming an important part of the general practice population. Although they have a similar range of medical conditions to the general population, there are some important differences in prevalence, risk factors, presentation and management of particular conditions. We use gastro-oesophageal reflux to illustrate how developmental disability may affect the presentation, assessment and management of a common condition.

Physiological responses to the menstrual cycle - Implications for the development of heat illness in female athletes

Fluctuations in estrogen and progesterone during the menstrual cycle can cause changes in body systems other than the reproductive system. For example, progesterone is involved in the regulation of fluid balance in the renal tubules and innervation of the diaphragm via the phrenic nerve. However, few significant changes in the responses of the cardiovascular and respiratory systems, blood lactate, bodyweight, performance and ratings of perceived exertion are evident across the cycle. Nevertheless, substantial evidence exists to suggest that increased progesterone levels during the luteal phase cause increases in both core and skin temperatures and alter the temperature at which sweating begins during exposure to both ambient and hot environments. As heat illness is characterised by a significant increase in body temperature, it is feasible that an additional increase in core temperature during the luteal phase could place females at an increased risk of developing heat illness during this time. In addition, it is often argued that physiological gender differences such as oxygen consumption, percentage body fat and surface area-to-mass ratio place females at a higher risk of heat illness than males. This review examines various physiological responses to heat exposure during the menstrual cycle at rest and during exercise, and considers whether such changes increase the risk of heat illness in female athletes during a particular phase of the menstrual cycle.

Cross-cultural differences in children's concepts of health and illness

INTRODUCTION: In spite of general agreement that cross-cultural research is needed in the health area, most existing investigations of children's development of health and illness-related concepts have involved samples from developed countries. The study examined the development of the concepts of health and illness as a function of subject's age, socio-economic status (SES), gender and grade level in a Brazilian sample of 96 elementary and junior high school students. METHODS: Subjects were interviewed individually and their ideas of health and illness were assessed through open-ended questions. Participants' answers were transcribed verbatim and subjected to content analysis. RESULTS: Chi-square analyses revealed significant age, school grade and SES-related differences in participants' concepts of health and illness. DISCUSSION AND CONCLUSION: The themes employed by subjects to define both health and illness were broadly consistent with those found by previous research. The study showed a predictable relationship between subject's age and school grade level and increasingly more highly differentiated and multidimensional concepts of health and illness. This investigation suggests that, for the most part, cross-cultural similarities in children's concepts of health and illness may be more striking than the differences.

Integrated Management of Childhood Illness: efficiency of primary health in Northeast Brazil

OBJECTIVE: The Integrated Management of Childhood Illness is a strategy designed to address major causes of child mortality. The aim of this study was to assess the impact of the strategy on the quality of child health care provided at primary facilities. METHODS: Child health quality of care and costs were compared in four states in Northeastern Brazil, in 2001. There were studied 48 health facilities considered to have had stable strategy implementation at least two years before the start of study, with 48 matched comparison facilities in the same states. A single measure of correct management of sick children was used to assess care provided to all sick children. Costs included all resources at the national, state, local and facility levels associated with child health care. RESULTS: Facilities providing strategy-based care had significantly better management of sick children at no additional cost to municipalities relative to the comparison municipalities. At strategy facilities 72% of children were correctly managed compared with 56% in comparison facilities (p=0.001). The cost per child managed correctly was US$13.20 versus US$21.05 in the strategy and comparison municipalities, respectively, after standardization for population size. CONCLUSIONS: The strategy improves the efficiency of primary facilities in Northeastern Brazil. It leads to better health outcomes at no extra cost.

Chagasic meningoencephalitis: case report of a recently included AIDS-defining illness in Brazil

Recently, reactivation of Chagas disease (meningoencephalitis and/or myocarditis) was included in the list of AIDS-defining illnesses in Brazil. We report a case of a 52-year-old patient with no history of previous disease who presented acute meningoencephalitis. Direct examination of blood and cerebrospinal fluid (CSF) showed Trypanosoma cruzi. CSF culture confirmed the diagnosis. Serological assays for T. cruzi and human immunodeficiency virus (HIV) were positive. Despite treatment with benznidazol and supportive measures, the patient died 24 hours after hospital admission. In endemic areas, reactivation of Chagas disease should always be considered in the differential diagnosis of meningoencephalitis among HIV-infected patients, and its presence is indicative of AIDS.
