How to prevent venous cannula orifice obstruction during extracorporeal circulation.

Venous cannula orifice obstruction is an underestimated problem during augmented cardiopulmonary bypass (CPB), which can potentially be reduced with redesigned, virtually wall-less cannula designs versus traditional percutaneous control venous cannulas. A bench model, allowing for simulation of the vena cava with various affluent orifices, venous collapse and a worst case scenario with regard to cannula position, was developed. Flow (Q) was measured sequentially for right atrial + hepatic + renal + iliac drainage scenarios, using a centrifugal pump and an experimental bench set-up (afterload 60 mmHg). At 1500, 2000 and 2500 RPM and atrial position, the Q values were 3.4, 6.03 and 8.01 versus 0.77*, 0.43* and 0.58* l/min: p<0.05* for wall-less and the Biomedicus(®) cannula, respectively. The corresponding pressure values were -15.18, -31.62 and -74.53 versus -46.0*, -119.94* and -228.13* mmHg. At the hepatic position, the Q values were 3.34, 6.67 and 9.26 versus 2.3*, 0.42* and 0.18* l/min; and the pressure values were -10.32, -20.25 and -42.83 versus -23.35*, -119.09* and -239.38* mmHg. At the renal position, the Q values were 3.43, 6.56 and 8.64 versus 2.48*, 0.41* and 0.22* l/min and the pressure values were -9.64, -20.98 and -63.41 versus -20.87 -127.68* and -239* mmHg, respectively. At the iliac position, the Q values were 3.43, 6.01 and 9.25 versus 1.62*, 0.55* and 0.58* l/min; the pressure values were -9.36, -33.57 and -44.18 versus -30.6*, -120.27* and -228* mmHg, respectivly. Our experimental evaluation demonstrates that the redesigned, virtually wall-less cannulas, allowing for direct venous drainage at practically all intra-venous orifices, outperform the commercially available control cannula, with superior flow at reduced suction levels for all scenarios tested.

Frequent users of the emergency department in a universal health coverage system : a randomized controlled trial of a case-management intervention

BACKGROUND: Frequent emergency department users represent a small number of patients but account for a large number of emergency department visits. They should be a focus because they are often vulnerable patients with many risk factors affecting their quality of life (QoL). Case management interventions have resulted in a significant decrease in emergency department visits, but association with QoL has not been assessed. One aim of our study was to examine to what extent an interdisciplinary case management intervention, compared to standard emergency care, improved frequent emergency department users' QoL. METHODS: Data are part of a randomized, controlled trial designed to improve frequent emergency department users' QoL and use of health-care resources at the Lausanne University Hospital, Switzerland. In total, 250 frequent emergency department users (≥5 attendances during the previous 12 months; ≥ 18 years of age) were interviewed between May 2012 and July 2013. Following an assessment focused on social characteristics; social, mental, and somatic determinants of health; risk behaviors; health care use; and QoL, participants were randomly assigned to the control or the intervention group (n=125 in each group). The final sample included 194 participants (20 deaths, 36 dropouts, n=96 in the intervention group, n=99 in the control group). Participants in the intervention group received a case management intervention by an interdisciplinary, mobile team in addition to standard emergency care. The case management intervention involved four nurses and a physician who provided counseling and assistance concerning social determinants of health, substance-use disorders, and access to the health-care system. The participants' QoL was evaluated by a study nurse using the WHOQOL-BREF five times during the study (at baseline, and at 2, 5.5, 9, and 12 months). Four of the six WHOQOL dimensions of QoL were retained here: physical health, psychological health, social relationship, and environment, with scores ranging from 0 (low QoL) to 100 (high QoL). A linear, mixed-effects model with participants as a random effect was run to analyze the change in QoL over time. The effects of time, participants' group, and the interaction between time and group were tested. These effects were controlled for sociodemographic characteristics and health-related variables (i.e., age, gender, education, citizenship, marital status, type of financial resources, proficiency in French, somatic and mental health problems, and behaviors at risk).

Relações entre características físicas e químicas de frutos de maracujazeiro-doce cultivado em Viçosa-MG

Foram avaliadas as relações entre os componentes físicos e químicos do maracujá-doce cultivado em Viçosa-MG. Cem frutos foram colhidos no estágio final do amadurecimento, com pericarpo com forte coloração amarelo-palha. Os frutos foram analisados quanto às características físicas e químicas, e os dados foram submetidos à análise de correlação de Pearson. Houve grande variação entre os valores de cada característica, sobremaneira para massa da matéria fresca e volume dos frutos, e massa da matéria fresca do pericarpo, que apresentaram médias de 194,53 ± 42,19 g, 253,85 ± 49,73 cm³ e 143,30 ± 40,50 g, respectivamente. O número de sementes variou de 110 a 379 por fruto. Verificaram-se correlações significativas entre a maioria das características avaliadas. O diâmetro apresentou correlação positiva com a massa da matéria fresca da polpa e negativa com o percentual de polpa, indicando que frutos maiores têm, proporcionalmente, menos polpa que os menores. A massa da matéria seca das sementes correlacionou-se positivamente com a massa da matéria fresca da polpa (0,6248**) e com a porcentagem de polpa (0,4375**). Semelhantemente, o número de sementes também apresentou correlação positiva com a massa da matéria fresca da polpa (0,5119**) e com a porcentagem de polpa (0,3957**), indicando que frutos com mais sementes apresentam maior rendimento de polpa. Contudo, houve correlação negativa entre número de sementes e teor de sólidos solúveis (-0,2161*), sugerindo a diluição do suco devido ao maior número de sementes e ao aumento da proporção de polpa. Também houve correlação negativa entre a espessura e a massa da matéria fresca do pericarpo e a porcentagem de polpa, indicando que a casca mais espessa reduz o diâmetro da cavidade interna do fruto, onde se acumula a polpa comestível.

Patients' characteristics associated with the decision of "do not attempt cardiopulmonary resuscitation" order in a Swiss hospital.

BACKGROUND: According to Swiss legislation, do not attempt cardiopulmonary resuscitation (DNACPR) order can be made at any time by patients only, unless the resuscitation is considered as futile, based on the doctors' evaluation. Little is known about how this decision is made, and which are the factors influencing this decision. METHODS: Observational, cross-sectional study was conducted between March and May 2013 on 194 patients hospitalized in the general internal medicine ward of a Swiss hospital. The associations between patients' DNACPR orders and gender, age, marital status, nationality, religion, number and type of comorbidities were assessed. RESULTS: 102 patients (53%) had a DNACPR order: 27% issued by the patient him/herself, 12% by his/her relatives and 61% by the medical team. Patients with a DNACPR order were significantly older: 80.7±10.8 vs. 67.5±15.1years in the "with" and "without" DNACPR order group, respectively, p<0.001. Oncologic disease was associated with a DNACPR order issued by the medical team (37.5% vs. 16.9% in the "with" and "without" DNACPR order group, respectively, p<0.05). Being protestant was associated with a DNACPR order issued by the patient (57.9% vs. 25.9% in the "with" and "without" DNACPR order group, respectively p<0.01). CONCLUSIONS: Over half of the patients admitted to a general internal medicine ward had a DNACPR order issued within the first 72h of hospitalization. Older age and oncologic disease were associated with a DNACPR decision by the medical team, while protestant religion was associated with a DNACPR decision by the patient.

Atividade antioxidante, citotóxica e antimicrobiana de Annona vepretorum Mart. (Annonaceae)

Annona vepretorum Mart. é uma espécie endêmica do bioma Caatinga, conhecida no Nordeste do Brasil como "araticum". Neste trabalho, o conteúdo de fenóis totais foi determinado pelo método de Folin-Ciocalteu. O teor de flavonoides totais também foi medido. A atividade antioxidante dos extratos foi analisada pelos métodos do sequestro do radical DPPH e inibição da auto-oxidação do β-caroteno, e comparada com o ácido ascórbico, BHA e BHT, utilizados como compostos de referência. A análise de citotoxidade foi realizada frente a linhagens de células HCT-116, OVCAR-8 e SF-295. O efeito antibacteriano foi avaliado pelo método de microdiluição. O conteúdo de fenóis totais do extrato etanólico (Av-EtOH) foi de 76,60 ± 5,57 mg de equivalente de ácido gálico/g. O conteúdo de flavonoides foi de 194,50 ± 11,72 mg de equivalente de catequina/g para o extrato hexânico. O extrato EtOH exibiu boa atividade antioxidante (IC50 = 98,87 ± 11,24 mg/mL) no método do DPPH. Os extratos mostraram atividade citotóxica e antibacteriana contra a maior parte das células e microrganismos testados. Pesquisas adicionais serão realizadas para o isolamento e a identificação dos principais constituintes fenólicos dos extratos.
