Complete anatomical myocardial revascularization is associated with better angina control and lower rates of cardiac events. However, in a significant number of patients treated by percutaneous ...coronary intervention (PCI), complete revascularization is not achieved. Thus, the aim of this study was to evaluate factors associated with incomplete myocardial revascularization (IMR) in multivessel PCI patients.
This was a cohort study involving 1,049 prospectively and consecutively revascularized patients through PCI with treatment of two or more vessels, between 2012 and 2014, divided into two groups: IMR (n = 324; 30.9%) and complete myocardial revascularization (n = 725; 69.1%).
IMR was significantly associated with older age (66.5 years vs. 64.1 years; p = 0.003), arterial hypertension (92.2% vs. 86.0%; p = 0.006), chronic renal failure (36.4% vs. 26.0%; p < 0.001), acute coronary syndrome (26.3% vs. 21.0%; p = 0.05), previous surgical revascularization (16.1% vs. 7.1%; p = 0.001), saphenous venous graft lesions (3.4% vs. 1.0%, p < 0.001), and chronic occlusions (3.3% vs. 1.4%, p = 0.005), as well as lower access to drug-eluting stents (57.8% vs. 64.8%; p = 0.002). In-hospital clinical outcomes did not differ between the groups.
IMR occurred in approximately one-third of treated cases, and a significant association was observed with a higher-risk clinical profile and with target lesion interventions commonly associated with lower procedure success. The degree of revascularization had no impact on in-hospital clinical outcomes.
A revascularização miocárdica anatômica completa está associada a um melhor controle dos sintomas anginosos e a menores índices de eventos cardíacos maiores tardios. No entanto, em substancial número de pacientes tratados por meio de intervenção coronária percutânea (ICP), não logramos sua obtenção. Assim, nosso objetivo foi avaliar os fatores associados à revascularização miocárdica incompleta (RMI) em casos de ICP multiarterial.
Estudo de coorte envolvendo 1.049 pacientes revascularizados de forma prospectiva e consecutiva por meio de ICP com tratamento de dois ou mais vasos, entre 2012 e 2014, divididos em dois grupos: RMI (n = 324; 30,9%) e revascularização miocárdica completa (n = 725; 69,1%).
A RMI foi significativamente associada a faixa etária maior (66,5 anos vs. 64,1 anos; p = 0,003), hipertensão arterial (92,2% vs. 86,0%; p = 0,006), insuficiência renal crônica (36.4% vs. 26.0%; p < 0,001), síndrome coronariana aguda (26,3% vs. 21,0%; p = 0,05), revascularização cirúrgica prévia (16,1% vs. 7,1%; p = 0,001), lesões em enxertos venosos (3,4% vs. 1,0%; p < 0,001) e oclusões crônicas (3,3% vs. 1,4%; p = 0,005), bem como a menor acesso a stents farmacológicos (57,8% vs. 64,8%; p = 0,002). Os resultados clínicos hospitalares não diferiram entre os grupos.
A RMI ocorreu em cerca de um terço dos casos tratados, tendo sido observada associação significativa, com um perfil clínico de maior risco e com intervenções em lesões alvo comumente associadas com menor sucesso do procedimento. O grau de revascularização não gerou impacto nos resultados clínicos da fase hospitalar.

The installation of micro generation systems on-board of electric vehicles is a solution that can contribute to improve the performance of this type of vehicles. Embedded generation systems increase ...the autonomy of electric vehicles and can reduce the number of times and duration of the recharging process of their energy storage systems. In this work, the influence of installing micro-generation systems dedicated to electrical vehicles is investigated. In particular, the integration of photovoltaic modules in a commercial electric vehicle ("Fiat Seicento Elettra") was analyzed. Starting from this solution, a computational application was developed allowing the users/students to configure the vehicle (including: type of vehicle, slope of the route, type of photovoltaic panels, location and month of the year). Therefore, the main outputs of the developed computational application are the distance run according to the energy generated by the photovoltaic modules, the power balance of the photovoltaic panels, the greenhouse gas emissions and the vehicle consumptions for urban, extra urban and combined circuits.
The following text deals with the general principles and legal rules regarding evidence and evidence taking in the Portuguese legal system. Based on the rules foreseen in legal texts, as well as ...court decisions and national literature, the authors approach the general theory behind the current rules and notions in force while also referencing the specifications of the means of proof in use in legal practice.
To analyze and compare COVID-19 patient characteristics, clinical management and outcomes between the peak and plateau periods of the first pandemic wave in Portugal.
This was a multicentric ...ambispective cohort study including consecutive severe COVID-19 patients between March and August 2020 from 16 Portuguese intensive care units. The peak and plateau periods, respectively, weeks 10 - 16 and 17 - 34, were defined.
Five hundred forty-one adult patients with a median age of 65 57 - 74 years, mostly male (71.2%), were included. There were no significant differences in median age (p = 0.3), Simplified Acute Physiology Score II (40 versus 39; p = 0.8), partial arterial oxygen pressure/fraction of inspired oxygen ratio (139 versus 136; p = 0.6), antibiotic therapy (57% versus 64%; p = 0.2) at admission, or 28-day mortality (24.4% versus 22.8%; p = 0.7) between the peak and plateau periods. During the peak period, patients had fewer comorbidities (1 0 - 3 versus 2 0 - 5; p = 0.002) and presented a higher use of vasopressors (47% versus 36%; p < 0.001) and invasive mechanical ventilation (58.1 versus 49.2%; p < 0.001) at admission, prone positioning (45% versus 36%; p = 0.04), and hydroxychloroquine (59% versus 10%; p < 0.001) and lopinavir/ritonavir (41% versus 10%; p < 0.001) prescriptions. However, a greater use of high-flow nasal cannulas (5% versus 16%, p < 0.001) on admission, remdesivir (0.3% versus 15%; p < 0.001) and corticosteroid (29% versus 52%, p < 0.001) therapy, and a shorter ICU length of stay (12 days versus 8, p < 0.001) were observed during the plateau.
There were significant changes in patient comorbidities, intensive care unit therapies and length of stay between the peak and plateau periods of the first COVID-19 wave.

A obstrução intestinal constitui complicação freqüente, de etiologia multifatorial, apresentação clínica variável e alta morbidade. Uma vez esgotados os recursos conservadores em casos específicos, a ...laparotomia exploradora é empregada para o diagnóstico final e tratamento em grande número de pacientes. Apesar do sucesso da via laparoscópica no manuseio de diversas afecções, a utilização desta via na abordagem inicial da obstrução do intestino delgado tem sido bastante limitada e alvo de numerosas críticas. Entretanto, o acúmulo de experiência com o método nos últimos anos, aliado ao avanço tecnológico e instrumental, têm permitido tratar número cada vez maior de pacientes obstruídos por meio do acesso laparoscópico. Assim, o surgimento de novos instrumentos como grampeadores laparoscópicos, pinças e trocáteres menos traumáticos ajudaram a tornar a videolaparoscopia factível e segura nestes pacientes. Neste artigo, os autores apresentam uma revisão sobre o papel da vídeo-cirurgia em casos selecionados de obstrução intestinal, ressaltando a contribuição dos métodos minimamente invasivos para o arsenal diagnóstico e terapêutico desta importante complicação.
