Lima, Adalberto de;Gonalves, Carlos Eduardo;
Revista Brasileira de Economia , 2011, DOI: 10.1590/S0034-71402011000400001
Abstract: this paper studies the relationship between political regimes duration and growth using data for 1950-2005. using econometric duration models to evaluate the so-called modernization hypothesis we find evidence supporting the idea that a democracy enjoys longer duration in richest and more educated countries. however, the duration of dictatorships does not seem to be affected by economic growth or the rise of educational attainment.

Paula, Márcia Beatriz Cardoso de;Costa, Idessania Nazareth da;Freitas, Paula de Albuquerque;Limongi, Jean Ezequiel;Pajuaba Neto, Adalberto de Albuquerque;Pinto, Rogério de Melo Costa;Gonalves, Ana Lúcia Ribeiro;Costa-Cruz, Julia Maria;
Revista da Sociedade Brasileira de Medicina Tropical , 2010, DOI: 10.1590/S0037-86822010000100003
Abstract: introduction: from an epidemiological point of view, more than 120 species of triatomine (hemiptera, reduviidae) are known. the occurrence and positivity for trypanosoma cruzi in triatomines in 16 municipalities of the triangulo mineiro and alto paranaíba were evaluated from january 2002 to december 2004. methods: the triatomines were captured basically according to the classic norms of the national health foundation. the parasitological exams of the triatomines were conducted according to the technique described by the ministry of health. during the study period, 990 specimens of triatomines were captured and of these, 771 could be examined. results: five species were identified: triatoma sordida, panstrongylus diasi, panstrongylus megistus, panstrongylus geniculatus and rhodnius neglectus. triatoma sordida represented 71.5% of all the triatomines captured, followed by panstrongylus megistus (18%), rhodnius neglectus (9.3%), panstrongylus diasi (0.8%) and panstrongylus geniculatus (0.4%). of the total number of triatomines examined, 2.7% were positive for trypanosoma cruzi. panstrongylus megistus was the species that presented the highest rates of infection by trypanosoma cruzi (8.3%), followed by rhodnius neglectus (2.9%) and triatoma sordida (1.4%). conclusions: there is a need to adapt to new circumstances in epidemiology, with greater emphasis on entomological surveillance, since the potential for adaptation of secondary species of triatomines exists, especially where chagas' disease is already under control.

Abstract: introduction: the increasing practice of ecotourism and rural tourism in the state of minas gerais, brazil, highlights the importance of studies concerning the occurrence of potential intermediate hosts of schistosoma mansoni. this study aimed to identify species of biomphalaria snails in municipalities along the estrada real, an important brazilian tourism project. methods: the specimens were collected in different water collections of 36 municipalities along the estrada real in the southeast of the state of minas gerais. biomphalaria species were characterized using both morphological and molecular approaches. the research was conducted between august 2005 and september 2009 and all the sites visited were georeferenced using gps. results: six biomphalaria species were found in 30 of the 36 municipalities studied: glabrata, tenagophila, straminea, peregrina, occidentalis and schrammi. the first three species of biomphalaria, recognized as intermediate hosts of s. mansoni, were present in 33.3%, 47.2% and 8.3% of the municipalities studied, respectively. the mollusks were found in different types of water collections and no infection by s. mansoni was detected. the highest occurrence of biomphalaria concentration was verified in the area covered by the caminho novo route (diamantina/mg to rio de janeiro/rj). conclusions: considering the occurrence of schistosomiasis in the state of minas gerais and the socioeconomic repercussions involved in the estrada real project, this work focuses on the vulnerability of water collections due to the presence of biomphalaria mollusks and emphasizes the need for epidemiological surveillance and sanitary and educational measures integrated with the local community and tourism sectors.
Stress, Executive Function, Resilience and Quality of Life in Portuguese Subjects in Situations of Economic Insufficiency and Unemployment  [PDF]
Eduardo Gonalves, Saul Neves de Jesus
Open Journal of Psychiatry (OJPsych) , 2015, DOI: 10.4236/ojpsych.2015.54040
Abstract: The aim of this study is the investigation of the impact of stress of Portuguese subjects in situations of economic insufficiency and unemployment on executive function and quality of life and the coping strategies and resilience skills used. The sample consists of 41 participants. The psychometric instruments used are validated for Portuguese population, measure (perceived) stress, coping, material deprivation, resilience and quality of life, defined by World Health Organization. Executive function has been evaluated through performances at Stroop and Berg tasks. It has been concluded that, in this population, resilience skills and active coping strategies are positively correlated with quality of life. Quality of life is negatively correlated with material deprivation. Active coping strategies are supported by adequate executive function, which neurobiological substrate is dorso-lateral prefrontal cortex. Not active coping strategies correlate negatively with cognitive flexibility, suggesting the presence of a deficit at infero-lateral prefrontal cortex.

Memórias do Instituto Oswaldo Cruz , 2011, DOI: 10.1590/S0074-02762011000600012
Abstract: throughout brazil, cryptococcus neoformans is the cause of cryptococcosis, whereas cryptococcus gattii is endemic to the northern and northeastern states. in this study, the molecular types of 63 cryptococcal isolates recovered from the cerebrospinal fluid of meningitis patients diagnosed between 2008-2010 in teresina, piauí, brazil, were analysed. out of the 63 patients, 37 (58.7%) were human immunodeficiency virus (hiv)-positive and 26 (41.3%) were hiv-negative. ura5-restriction fragment length polymorphism analysis identified 37/63 (58.7%) isolates as the c. neoformans vni genotype, predominantly in hiv-positive patients (32/37, 86.5%), and 24/63 (38.1%) as the c. gattii vgii genotype, mostly in hiv-negative patients (21/26, 80.8%). the occurrence of c. gattii vgii in six apparently healthy children and in seven adolescents/young adults in this region reaffirms the endemic occurrence of c. gattii vgii-induced primary cryptococcosis and early cryptococcal infection. lethality occurred in 18/37 (48.6%) of the hiv-positive subjects and in 13/26 (50%) of the hiv-negative patients. our results provide new information on the molecular epidemiology of c. neoformans and c. gattii in brazilian endemic areas.

Abstract: the present paper reports a laboratory investigation performed between the years of 2000 and 2002 to stydy a virological surveillance program introduced in the state of piauí to support an epidemiological survey of the disease. dengue virus type 3 (denv-3) existence in the state was detected in may 2002 when a high number of dengue cases due to denv-1 and denv-2 were reported. an assessment on the population knowledge about the disease and its transmission showed that almost 50% of the population were still unaware of the epidemiological features of dengue.
High frequency heart rate variability evoked by repetitive transcranial magnetic stimulation over the medial prefrontal cortex: A preliminary investigation on brain processing of acute stressor-evoked cardiovascular reactivity  [PDF]
Eduardo Manuel Gonalves, Saul Neves de Jesus
Open Journal of Psychiatry (OJPsych) , 2013, DOI: 10.4236/ojpsych.2013.34035
Abstract:

Introduction: Transcranial Magnetic Stimulation (TMS) is a non-invasive technique for brain stimulation. Repetitive TMS (rTMS) over the medial Prefrontal Cortex (mPFC), Broadman Area 10 (BA10) may stimulate transynaptically perigenual Anterior Cingulate Cortex (pACC, BA 33), insula, amigdala, hypothalamus and connected branches of the Autonomic Nervous System (ANS) involved in stressorevoked cardiovascular reactivity. Stressors are associated with an increase in sympathetic cardiac control, a decrease in parasympathetic control, or both, and, consequently, an increase in systolic/stroke volume, total vascular impedance/resistance and heart rate, a decrease of baroreflex sensitivity, i.e., an increase in blood pressure/arterial tension. Objectives and Aims: The present work aims, using TMS and accordingly to Gianaros modeling, based on functional neuroimaging studies and previous neuroanatomical data from animal models, to probe the connectivity of brain systems involved in stressor-evoked cardiovascular reactivity and to explore TMS potential as a tool for detection and stratification of individual differences concerning this reactivity and hemorreological risk factors correlated with the development of Coronary Heart Disease (CHD). Methods: Both subjects, a 52 years old male and a 40 years old female with previous increased Low Frequency (LF)/High Frequency (HF) Heart Rate Variability (HRV) ratios (respectively, 4.209/3.028) without decompensated cardiorespiratory symptoms, gave informed consent, and ethico-legal issues have been observed. Electroencephalographic (EEG) monitoring has been performed for safety purposes. Immediately after administration, over the mPFC, of 15 pulses of rTMS, during 60 second, with an inductive electrical current, at the stimulating coil, of 85.9 Ampère per

Abstract:


Introduction: Studies on attitudes and practices are increasingly used but not specifically related to the motivations for the use of reproductive health care among women of fertile age, living in urban areas and in different social contexts. Objectives: The aim of this study was to estimate the associations between the variables of social status (degree of poverty in the studied groups) and the variables of fecundity (representations, tensions, practices and control of fertility) and, in addition, to compare access to health care in the different studied groups, assessing the association between use of maternal health care and poverty in urban areas. Design: A case-control study was conducted in the Municipality of Lisbon, Portugal, with a total sample of 1513 women of fertile age: 499 cases of women considered very poor were selected from the database of beneficiaries of RSI (Social Welfare Payment for Inclusion); 1014 controls (two controls for each selected case), divided as 507 poor women selected from the other beneficiaries of Santa Casa da Misericórdia in Lisbon and 507 non-poor women selected from four Health Centers from the Municipality of Lisbon, Portugal. A total of 1054 women answered the questionnaire: 304 cases (response rate of 61%) and 750 (response rate of 74%) controls. The statistical analysis involved descriptive analysis and multinomial logistic regression. Results: The analysis confirms the association between poverty and patterns and representations of fecun

dity regarding pregnancy planning. The results of this study thus show the existence of different distributions on several variables and the gradients of poverty. Regarding access to health care, the major impact of poverty on women
