    Otimizaçao do marcapasso na ressincronizaçao cardíaca: importância da ecocardiografia

    Get PDF
    A terapia de ressincronizaçao cardíaca (TRC) promove beneficios clínicos para a maior parte dos pacientes com insuficiência cardíaca refratária secundária a disfunçao ventricular esquerda importante e prolongada conduçao interventricular. Uma programaçao adequada do atraso atrioventricular pode ser também importante para maximizar a resposta da funçao ventricular esquerda. Vários métodos Doppler-ecocardiográficos têm sido relatados como de grande utilidade para determinaçao do intervalo atrioventricular (IAV) ideal. Esta revisao abordará os vários parâmetros Doppler-ecocardiográficos utilizados na programaçao do IAV ótimo em pacientes submetidos a TRC

    Influence of EPICardial adipose tissue in HEART diseases (EPICHEART) study: Protocol for a translational study in coronary atherosclerosis

    Get PDF
    Accumulation of epicardial adipose tissue (EAT) is associated with coronary artery disease (CAD) and increased risk of coronary events in asymptomatic subjects and low-risk patients, suggesting that EAT promotes atherosclerosis in its early stage. Recent studies have shown that the presence of CAD affects the properties of adjacent EAT, leading to dynamic changes in the molecular players involved in the interplay between EAT and the coronary arteries over the history of the disease. The role of EAT in late-stage CAD has not been investigated.coronárioResumoIntroduc¸ão:Acumulac¸ão de tecido adiposo epicárdico (TAE) tem sido associado a doenc¸acoronária aterosclerótica (DC) e aumento do risco de eventos coronários em indivíduos ass-intomáticos e doentes de baixo risco, sugerindo que o TAE pode promover fases precoces daDC. Estudo recentes mostraram que a presenc¸a de DC afeta as características do TAE adja-cente levando a modificac¸ões dinâmicas nos mediadores envolvidos na comunicac¸ão entre oTAE e as artérias coronárias ao longo da história da DC. O papel doTAE nas fases avanc¸adas daaterosclerose coronária não foi investigado.Objetivos: Através de análise comparativa com o tecido adiposo mediastínico e subcutâneo,pretendemos investigar se o volume do TAE, avaliado por tomografia computadorizada (TC), eo seu proteoma, avaliado por espectrometria de massa técnica de SWATH, estão associados aestadios avanc¸ados da DC numa coorte de estenose aórtica grave.Métodos: O estudo EPICHEART (NCT03280433) é um estudo prospetivo que inclui doentescom estenose aórtica grave referenciados para substituic¸ão eletiva da válvula aórtica, cujoprotocolo envolve avaliac¸ão pré-operatória clínica, nutricional, ecocardiográfica, por TC eangiografia coronária invasiva. Durante a cirurgia cardíaca, colhemos amostras de tecido adi-poso epicárdico, mediastínico e subcutâneo para análise do seu proteoma por espectrometriade massa técnica de SWATH. Adicionalmente, colhemos líquido pericárdico, sangue venoso per-iférico e do seio coronário para investigar mediadores de DC derivados do TAE na circulac¸ãosistémica e local.Conclusão: Desenhámos um estudo de translac¸ão para explorar a associac¸ão da quantidade equalidade do TAE com a DC tardia. Esperamos identificar mediadores da comunicac¸ão recíprocaentre o TAE e as artérias coronárias que estão envolvidos na patogénese das fases avanc¸adas daDC, especialmente, calcificac¸ão coronária, os quais podem servir como novos alvos terapêuticose soluc¸ões de engenharia biomédica para visualizac¸ão da DC

    MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugal

    Mammals are threatened worldwide, with 26% of all species being includedin the IUCN threatened categories. This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records. The data set includes 13 types of records: (1) burrowsjsoil moundsjtunnel, (2) capture, (3) colony, (4) dead animaljhairjskullsjjaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8),observation in shelters, (9) photo trappingjvideo, (10) predators dietjpelletsjpine cones/nuts, (11) scatjtrackjditch, (12) telemetry and (13) vocalizationjecholocation. The spatial uncertainty of most records ranges between 0 and100 m (76%). Rodentia (n=31,573) has the highest number of records followedby Chiroptera (n=18,857), Carnivora (n=18,594), Lagomorpha (n=17,496),Cetartiodactyla (n=11,568) and Eulipotyphla (n=7008). The data setincludes records of species classified by the IUCN as threatened(e.g.,Oryctolagus cuniculus[n=12,159],Monachus monachus[n=1,512],andLynx pardinus[n=197]). We believe that this data set may stimulate thepublication of other European countries data sets that would certainly contrib-ute to ecology and conservation-related research, and therefore assisting onthe development of more accurate and tailored conservation managementstrategies for each species.

    Guidelines for the use and interpretation of assays for monitoring autophagy (4th edition)1.

    Get PDF
    In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Thus, it is important to formulate on a regular basis updated guidelines for monitoring autophagy in different organisms. Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to examine autophagy and related processes, and for reviewers to provide realistic and reasonable critiques of reports that are focused on these processes. These guidelines are not meant to be a dogmatic set of rules, because the appropriateness of any assay largely depends on the question being asked and the system being used. Moreover, no individual assay is perfect for every situation, calling for the use of multiple techniques to properly monitor autophagy in each experimental setting. Finally, several core components of the autophagy machinery have been implicated in distinct autophagic processes (canonical and noncanonical autophagy), implying that genetic approaches to block autophagy should rely on targeting two or more autophagy-related genes that ideally participate in distinct steps of the pathway. Along similar lines, because multiple proteins involved in autophagy also regulate other cellular pathways including apoptosis, not all of them can be used as a specific marker for bona fide autophagic responses. Here, we critically discuss current methods of assessing autophagy and the information they can, or cannot, provide. Our ultimate goal is to encourage intellectual and technical innovation in the field

    Mammals are threatened worldwide, with ~26% of all species being included in the IUCN threatened categories. This overall pattern is primarily associated with habitat loss or degradation, and human persecution for terrestrial mammals, and pollution, open net fishing, climate change, and prey depletion for marine mammals. Mammals play a key role in maintaining ecosystems functionality and resilience, and therefore information on their distribution is crucial to delineate and support conservation actions. MAMMALS IN PORTUGAL is a publicly available data set compiling unpublished georeferenced occurrence records of 92 terrestrial, volant, and marine mammals in mainland Portugal and archipelagos of the Azores and Madeira that includes 105,026 data entries between 1873 and 2021 (72% of the data occurring in 2000 and 2021). The methods used to collect the data were: live observations/captures (43%), sign surveys (35%), camera trapping (16%), bioacoustics surveys (4%) and radiotracking, and inquiries that represent less than 1% of the records. The data set includes 13 types of records: (1) burrows | soil mounds | tunnel, (2) capture, (3) colony, (4) dead animal | hair | skulls | jaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8), observation in shelters, (9) photo trapping | video, (10) predators diet | pellets | pine cones/nuts, (11) scat | track | ditch, (12) telemetry and (13) vocalization | echolocation. The spatial uncertainty of most records ranges between 0 and 100 m (76%). Rodentia (n =31,573) has the highest number of records followed by Chiroptera (n = 18,857), Carnivora (n = 18,594), Lagomorpha (n = 17,496), Cetartiodactyla (n = 11,568) and Eulipotyphla (n = 7008).
