Emprego e qualidade de vida na epilepsia do lobo temporal mesial com esclerose do hipocampo: há uma mudança após a cirurgia?

PURPOSE: The aim of this study was to evaluate in patients with mesial temporal lobe epilepsy (MTLE) with hippocampal sclerosis (HS): (1) employment patterns before and three years after epilepsy surgery and their impact in Quality of Life (QOL); (2) demographic and clinical variables associated with employment. METHODS: Data from 58 patients with diagnosis of refractory MTLE with HS who had corticoamygdalo-hippocampectomy were analyzed. The subjects answered to Brazilian validated version of the Epilepsy Surgery Inventory (ESI-55) before, and three years after surgery. In a semi-structured interview, sociodemographic and clinical characteristics were obtained. Changes in employment after surgery were classified in one of the three categories: (i) improvement status: those who were unemployed, no-formal employed, students, housewives and subjects who have never worked to employed category; (ii) unchanged status: no change in occupation; this category included subjects who were employed before and after the surgery, housewives, students, and the group who remained unemployed, receiving ill-health benefits or retired after the surgical treatment; and (iii) worsened status: loss of employment. RESULTS: Employment status did not show any significant change after surgery: in 51(87.9%) it remained unchanged, in six (10.3%) it improved, and one patient (1.7%), who was employed before the surgery, retired after that. In a subgroup of 22 patients employed after surgery, ten (45.5%) were seizure-free, seven (31.8%) had only rare auras, and five (22.7%) had seizures. In the group of improvement, 12 patients (70.5%) had no-formal employment and five (29.5%) had a formal job before surgery. After three years, 14 (63.6%) of 22 subjects were formally employed. Our data suggested that the employability was strongly correlated (p<0.05) with a positive perception of health-related quality of life measured by ESI-55, before and after surgical evaluation. CONCLUSION: Our study demonstrated in a homogeneous group of MTLE with HS, a modest, but positive relationship between surgical outcome and work gain, and that QOL had strong correlation with the fact of being employed.OBJETIVO: Avaliar o estado empregatício e a qualidade de vida (QV) de indivíduos com epilepsia do lobo temporal mesial (ELTM) com esclerose do hipocampo (EH) antes e três anos após a realização de corticoamigdalohipocampectomia e verificar as variáveis demográficas e clínicas associadas ao emprego. METODOLOGIA: 58 pacientes com ELTM com EH submetidos a corticoamigdalohipocampectomia foram avaliados antes e três anos após a cirurgia. Todos responderam ao Epilepsy Surgery Inventory (ES-I55) - versão brasileira como medida da QV, bem como a um breve questionário contendo dados sociodemográficos e clínicos. Alterações na situação de emprego após a cirurgia foram classificadas do seguinte modo: (i) melhora: indivíduos desempregados, com emprego não-formal, estudantes, donas-de-casa e aqueles que nunca haviam trabalhado e que estavam empregados três anos após a cirurgia; (ii) nenhuma mudança: aqueles que não obtiveram modificações em sua situação ocupacional. Esta categoria compreendeu indivíduos que permaneceram empregados, continuaram com atividades domésticas, estudantes, em auxílio doença, aposentados e os que nunca trabalharam; e (iii) piora: perda do emprego. RESULTADOS: A situação de emprego não mudou significativamente após a cirurgia: 51(87.9%) permaneceram com o mesmo estado empregatício anterior à cirurgia, seis (10.3%) tiveram melhora, e um paciente (1.7%), que estava empregado antes da cirurgia, aposentou-se. No subgrupo dos 22 pacientes empregados após três anos, dez (45.5%) estavam livres de crises, sete (31.8%) tinham apenas auras esporádicas e cinco (22.7%) permaneceram com crises. No grupo que obteve melhora, 12 pacientes (70.5%) eram autônomos antes da cirurgia e cinco (29.5%), tinham emprego formal. Na avaliação do terceiro ano após cirurgia, 14 (63.6%) dos 22 indivíduos conseguiram um emprego formal. Nosso estudo verificou que a QV manteve relação estatística positiva com o estado de trabalho (p<0.05). Aqueles que exerciam atividade remunerada tinham percepção mais positiva sobre sua QV, medida pelo ESI-55, antes e após o tratamento cirúrgico. CONCLUSÃO: Nosso estudo mostrou mudança modesta, mas positiva quanto à situação empregatícia após a cirurgia, bem como a importância de atividade produtiva para a QV, em um grupo homogêneo de indivíduos com ELTM e EH.Universidade Federal de São Paulo (UNIFESP) Departamento de Neurologia e Neurocirurgia Unidade de Pesquisa e Tratamento das EpilepsiasUNIFESP, Depto. de Neurologia e Neurocirurgia Unidade de Pesquisa e Tratamento das EpilepsiasSciEL

Systematic Analysis of FKBP Inducible Degradation Domain Tagging Strategies for the Human Malaria Parasite Plasmodium falciparum

Targeted regulation of protein levels is an important tool to gain insights into the role of proteins essential to cell function and development. In recent years, a method based on mutated forms of the human FKBP12 has been established and used to great effect in various cell types to explore protein function. The mutated FKBP protein, referred to as destabilization domain (DD) tag when fused with a native protein at the N- or C-terminus targets the protein for proteosomal degradation. Regulated expression is achieved via addition of a compound, Shld-1, that stabilizes the protein and prevents degradation. A limited number of studies have used this system to provide powerful insight into protein function in the human malaria parasite Plasmodium falciparum. In order to better understand the DD inducible system in P. falciparum, we studied the effect of Shld-1 on parasite growth, demonstrating that although development is not impaired, it is delayed, requiring the appropriate controls for phenotype interpretation. We explored the quantified regulation of reporter Green Fluorescent Protein (GFP) and luciferase constructs fused to three DD variants in parasite cells either via transient or stable transfection. The regulation obtained with the original FKBP derived DD domain was compared to two triple mutants DD24 and DD29, which had been described to provide better regulation for C-terminal tagging in other cell types. When cloned to the C-terminal of reporter proteins, DD24 provided the strongest regulation allowing reporter activity to be reduced to lower levels than DD and to restore the activity of stabilised proteins to higher levels than DD29. Importantly, DD24 has not previously been applied to regulate proteins in P. falciparum. The possibility of regulating an exported protein was addressed by targeting the Ring-Infected Erythrocyte Surface Antigen (RESA) at its C-terminus. The tagged protein demonstrated an important modulation of its expression.Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP)Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP)National Council for Scientific and Technological Development (CNPq)National Council for Scientific and Technological Development (CNPq)National Health and Medical Research Council of AustraliaNational Health and Medical Research Council of Australi

Evaluation of the process of reabilitation of a stretch of Riparian forest in Itapemirim river watershed - ES

Este estudo foi realizado em uma área de floresta ciliar em processo de recuperação mediante reabilitação.A área de estudo está localizada na sub-bacia hidrográfica do rio Itapemirim, no Município de Alegre, ES, Brasil.A ocupação e uso do solo antes da revegetação eram de pastagem com Brachiaria sp. A revegetação da áreafoi feita em 1997, com espécies autóctones e alóctones arbóreas, em arranjo de distribuição aleatório, em umaárea de 1,2 ha. Para a realização dos estudos foram feitos inventários florestais nos períodos de 2004/2005e 2005/2006, sendo medidos os indivíduos de hábito arbustivo e arbóreo com circunferência à altura do peito(CAP) > 5 cm e suas alturas totais. As espécies encontradas na área foram identificadas e classificadas de acordocom seus grupos ecológicos, síndromes de dispersão e presença silvestre, sendo calculados os parâmetros florísticos,a estrutura vertical e a dinâmica estrutural desse povoamento. O objetivo do trabalho foi avaliar o desenvolvimentodo povoamento implantado para subsidiar práticas silviculturais quanto à seleção e implantação de espécies pararevegetação de áreas de floresta ciliar degradadas, em condições semelhantes. Os resultados demonstraram quefoi implantado um povoamento florestal com grande diversidade de espécies e a estratificação em classes dealtura foi à semelhança de povoamentos heterogêneos naturais. As espécies identificadas como edificadoras darevegetação da área estudada foram: Anadenanthera colubrina, Caesalpinia leyostachia, Acacia auriculiformis,Acacia mangium, Handroanthus serratifolius, Inga edulis, Joannesia princeps, Pterogyne nitens, Enterelobiumcontortisiliquum, Tabernaemontana hystrix e Anthocephalus indicus. A distribuição em classes de tamanho dacomunidade implantada ocorre em forma de "J" reverso, havendo a predominância de indivíduos pioneiros emtodas as classes de CAP. A dinâmica da estrutura horizontal apontou que, para o sucesso, continuidade e desenvolvimentoda recuperação da área, seja monitorada a regeneração natural em relação à sua presença e à eficiência dos fatoresbióticos e abióticos que nela interferem. A não observância de indivíduos arbustivos e arbóreos regenerados naturalmente,na classe de inclusão do estudo, indica a fragilidade inicial da área rumo à sustentabilidade do sistema.The study was realized in an area of riparian forest in process by means of rehabilitation. Thestudy area is located in Rio Itapemirim, in Alegre city, Brazil. The occupation and use of the soil beforethe recovery were of pasture with Brachiaria sp. The recovery of this area was in 1997, with autochthonousand allochthonous species, in casually distribution arrangement, in an area of 1,2 ha. For this studies wasrealized forest inventories in the periods of 2004/2005 and 2005/2006, being measured the arboreal individualswith circumference at breast height (CBH) and total heights. The species found in the area were identifiedand classified in this ecological groups, dispersion syndromes and wild presence, it forms calculated thefloristic parameters, the vertical structure and the structural dynamics of this plantation. The objective ofthis work went evaluate the development of the plantation implanted to subsidize practical silviculture withrelationship to the selection and plantation of species for the revegetation of degraded areas of riparianforest, in similar conditions. The results of the studies demonstrated that a forest plantation was implantedwith great diversity of species and the bedding in height classes it went to the likeness of natural heterogeneous.The species identified as builders of the plantation of the studied area were: Anadenanthera colubrina, Caesalpinia leyostachia, Acacia auriculiformis, Acacia mangium, Handroanthus serratifolius, Inga edulis, Joannesia princeps,Pterogyne nitens, Enterelobium contortisiliquum, Tabernaemontana hystrix, and Anthocephalus indicus . Theimplanted community's distribution diametric happens in reverse J shape having the pioneer individuals'predominance in all the classes of CBH. The dynamics of the horizontal structure points that for the success,continuity and development of the recovery of the area, the natural regeneration be monitored in relationto its presence and efficiency of the biotic factors and abiotic those interfere in the same. The not tree individualsobservance in natural regeneration, in the class of inclusion of the study, indicate the initial fragility of thearea heading for sustentabilidade of the system

International Society of Human and Animal Mycology (ISHAM)-ITS reference DNA barcoding database - the quality controlled standard tool for routine identification of human and animal pathogenic fungi

Human and animal fungal pathogens are a growing threat worldwide leading to emerging infections and creating new risks for established ones. There is a growing need for a rapid and accurate identification of pathogens to enable early diagnosis and targeted antifungal therapy. Morphological and biochemical identification methods are time-consuming and require trained experts. Alternatively, molecular methods, such as DNA barcoding, a powerful and easy tool for rapid monophasic identification, offer a practical approach for species identification and less demanding in terms of taxonomical expertise. However, its wide-spread use is still limited by a lack of quality-controlled reference databases and the evolving recognition and definition of new fungal species/complexes. An international consortium of medical mycology laboratories was formed aiming to establish a quality controlled ITS database under the umbrella of the ISHAM working group on "DNA barcoding of human and animal pathogenic fungi." A new database, containing 2800 ITS sequences representing 421 fungal species, providing the medical community with a freely accessible tool at http://www.isham.org and http://its.mycologylab.org/ to rapidly and reliably identify most agents of mycoses, was established. The generated sequences included in the new database were used to evaluate the variation and overall utility of the ITS region for the identification of pathogenic fungi at intra-and interspecies level. The average intraspecies variation ranged from 0 to 2.25%. This highlighted selected pathogenic fungal species, such as the dermatophytes and emerging yeast, for which additional molecular methods/genetic markers are required for their reliable identification from clinical and veterinary specimens.This study was supported by an National Health and Medical Research Council of Australia (NH&MRC) grant [#APP1031952] to W Meyer, S Chen, V Robert, and D Ellis; CNPq [350338/2000-0] and FAPERJ [E-26/103.157/2011] grants to RM Zancope-Oliveira; CNPq [308011/2010-4] and FAPESP [2007/08575-1] Fundacao de Amparo Pesquisa do Estado de So Paulo (FAPESP) grants to AL Colombo; PEst-OE/BIA/UI4050/2014 from Fundacao para a Ciencia e Tecnologia (FCT) to C Pais; the Belgian Science Policy Office (Belspo) to BCCM/IHEM; the MEXBOL program of CONACyT-Mexico, [ref. number: 1228961 to ML Taylor and [122481] to C Toriello; the Institut Pasteur and Institut de Veil le Sanitaire to F Dromer and D Garcia-Hermoso; and the grants from the Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq) and the Fundacao de Amparo a Pesquisa do Estado de Goias (FAPEG) to CM de Almeida Soares and JA Parente Rocha.

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection
