A doação de órgãos é um processo complexo que desafia os profissionais e gestores do sistema de saúde. Este estudo objetiva apresentar um modelo teórico de organização do cuidado ao paciente em morte encefálica e o processo de doação de órgãos, balizado pelas principais ideias do pensamento Lean que possibilitam a melhoria da produção a partir de ciclos de planejamentos e criação de um ambiente propício para o sucesso da sua implementação. O pensamento Lean pode tornar mais eficaz e eficiente o processo de doação de órgãos e contribuir com a sua melhoria, a partir da sistematização das informações e capacitação dos profissionais para a excelência do cuidado. O modelo apresentado configura-se como um referencial disponível para validação e aplicação pelos profissionais e gestores de saúde e enfermagem na prática da gestão do cuidado ao paciente potencial doador de órgãos em morte encefálica e respectiva demanda por transplante.

Deep thiopental anesthesia alters steady-state glucose homeostasis but not the neurochemical profile of rat cortex.

Barbiturates are regularly used as an anesthetic for animal experimentation and clinical procedures and are frequently provided with solubilizing compounds, such as ethanol and propylene glycol, which have been reported to affect brain function and, in the case of (1)H NMR experiments, originate undesired resonances in spectra affecting the quantification. As an alternative, thiopental can be administrated without any solubilizing agents. The aim of the study was to investigate the effect of deep thiopental anesthesia on the neurochemical profile consisting of 19 metabolites and on glucose transport kinetics in vivo in rat cortex compared with alpha-chloralose using localized (1)H NMR spectroscopy. Thiopental was devoid of effects on the neurochemical profile, except for the elevated glucose at a given plasma glucose level resulting from thiopental-induced depression of glucose consumption at isoelectrical condition. Over the entire range of plasma glucose levels, steady-state glucose concentrations were increased on average by 48% +/- 8%, implying that an effect of deep thiopental anesthesia on the transport rate relative to cerebral glucose consumption ratio was increased by 47% +/- 8% compared with light alpha-chloralose-anesthetized rats. We conclude that the thiopental-induced isoelectrical condition in rat cortex significantly affected glucose contents by depressing brain metabolism, which remained substantial at isoelectricity.

Max Reger (1873-1916) i Karl Straube (1873-1950) : tradició i evolució històrica de l'orgue a Alemanya

El present treball es centra en la relaci ó entre Max Reger i Karl Straube i les seves conseqüències interpretatives, tot vinculant-la amb els corrents socials, est ètics i musicals de tot el segle XIX i principis del segle XX. S'avalua el rellevament de la col ·laboració entre compositor i organista, recorrent a expressions i reflexions dels propis protagonistes i de persones properes a ambd ós. La metodologia es basa en l'an àlisi i la comparaci ó de materials editats i aut ògrafs, manuscrits, cartes, i enregistraments amb la finalitat d'aclarir una relaci ó humana, professional i musical de gran envergadura per la hist òria de l'orgue a Alemanya.

Abstract

A double-quadrature radiofrequency coil design for proton-decoupled carbon-13 magnetic resonance spectroscopy in humans at 7T

Purpose Carbon-13 magnetic resonance spectroscopy (13C-MRS) is challenging because of the inherent low sensitivity of 13C detection and the need for radiofrequency transmission at the 1H frequency while receiving the 13C signal, the latter requiring electrical decoupling of the 13C and 1H radiofrequency channels. In this study, we added traps to the 13C coil to construct a quadrature-13C/quadrature-1H surface coil, with sufficient isolation between channels to allow simultaneous operation at both frequencies without compromise in coil performance. Methods Isolation between channels was evaluated on the bench by measuring all coupling parameters. The quadrature mode of the quadrature-13C coil was assessed using in vitro 23Na gradient echo images. The signal-to-noise ratio (SNR) was measured on the glycogen and glucose resonances by 13C-MRS in vitro, compared with that obtained with a linear-13C/quadrature-1H coil, and validated by 13C-MRS in vivo in the human calf at 7T. Results Isolation between channels was better than â^'30 dB. The 23Na gradient echo images indicate a region where the field is strongly circularly polarized. The quadrature coil provided an SNR enhancement over a linear coil of 1.4, in vitro and in vivo. Conclusion It is feasible to construct a double-quadrature 13C-1H surface coil for proton decoupled sensitivity enhanced 13C-NMR spectroscopy in humans at 7T.

Current developments in the radiotherapy approach to elderly and frail patients with glioblastoma multiforme.

The benefit of postoperative radiotherapy (RT) has been demonstrated in elderly patients aged 65 years or older with glioblastoma multiforme. Hypofractionated RT schedules can reduce the time and morbidity of treatment while maintaining comparable survival outcomes to lengthy conventional RT. Current international randomized clinical trials are studying the optimized hypofractionated RT regimens, hypofractionated RT in comparison with temozolomide chemotherapy and hypofractionated RT in comparison with the same RT plus temozolomide. Given the guarded prognosis of the elderly and frail patients, quality of life and side effects of treatment should be closely examined. As more than half of cancers in the world occur in developing countries, hypofractionated RT could be better utilized as a cost-effective treatment for this group of patients.
