Wills and Holmes-Rovner (2006) highlight the fact that despite growing interest in the role of patient preferences and shared decision making with clinicians in the general health services research community, relatively little is known about the impact of these preferences and processes on actual decisions, service delivery engagement, or intervention outcomes in the mental health field. This commentary expands on three important points raised in Wills and Holmes-Rovner's article: (a) the need for more and better research on values assessment, (b) contextual factors in the decision-making process, and (c) the measurement of patient preferences regarding their level of involvement in decision making. 相似文献

Summary Hepatolithiasis is a common disease in East Asia though very rare in the West. Four cases of hepatolithiasis in which calculi were incidentally found in the peripheral branches of the intrahepatic biliary tree at autopsy are described and compared with hepatolithiasis involving the major branches of the intrahepatic biliary tree. These four cases were all elderly, three patients were male and one female. The calculi were brown pigment stones in each case, as seen in the major branch type. The stone-containing ducts showed mild fibrosis and glandular proliferation with inflammatory changes in three cases; these changes were marked in the fourth case. The hepatic parenchyma around the stone-containing ducts was atrophic or collapsed in all four cases. The major branches of the intrahepatic biliary tree as well as the extrahepatic tree failed to show findings suggestive of bacterial infections or biliary anomalies. These data suggest that brown pigment stones develop primarily in the peripheral ducts in the liver. It remains uncertain whether the peripheral type eventually progresses to the major type or not. 相似文献

Based on the results of cytological studies, it has been assumed that Cyanidioschyzon merolae does not contain actin genes. However, Southern hybridization of C. merolae cell-nuclear DNA with a yeast actin-gene probe has suggested the presence of an actin gene in the C. merolae genome. In the present study, an actin gene was isolated from a C. merolae genomic library using a yeast actin-gene probe. The C. merolae actin gene has no intron. The predicted actin is composed of 377 amino acids and has an estimated molecular mass of 42003 Da. Southern hybridization indicated that the C. merolae genome contains only one actin gene. This gene is transcribed at a size of 2.4 kb. When Southern hybridization was performed with C. merolae chromosomes separated by pulsed-field gel electrophoresis, a band appeared on unseparated chromosomes XI and XII. A phylogenetic tree based on known eucaryote actin-gene sequences revealed that C. merolae diverged after the division of Protozoa, but before the division of Fungi, Animalia and Chlorophyta. 相似文献

Co-localization of calcitonin gene-related peptide-like immunoreactivity with substance P in cutaneous, vascular and visceral sensory neurons of guinea pigs 总被引:19,自引:0,他引:19

Calcitonin gene-related peptide (CGRP) has been immunohistochemically co-localized with substance P (SP) in capsaicin-sensitive, varicose axons supplying the skin, viscera and cardiovascular system of the guinea pig. After treatment with colchicine in vitro, 82% of SP neurons in the dorsal root ganglia contained CGRP-like immunoreactivity while 96% of CGRP neurons were immunoreactive for SP. Both CGRP- and SP-like immunoreactive material are transported peripherally and centrally from dorsal root ganglia. Thus, in tissues such as the gut where there are intrinsic nerves containing SP but lacking CGRP, CGRP-like immunoreactivity is a useful means of specifically labelling axons of most sensory neurons containing SP. 相似文献

Numerical simulation of aerosol particle transport by oscillating flow in respiratory airways 总被引:2,自引:0,他引:2

Particle transport by oscillating flow in a tapered channel or in a tapered tube was computed from the complete equations
of motion. These geometries represent a simplified model of the divergent flow field of the mammalian bronchial tree. The
computed deformation profile of a line of particles, transported by the oscillatory motion, was compared with prior experimental
results and analytical calculations. All three methods agree that there is transport in the divergent direction of the tube
by an axial stream of steady drift in the core for moderately high frequency of oscillation (Womersley parameter in the range
of 1 to 10). Bidirectional flow is established by an annular stream in the convergent direction, with no net flow on integral
cycles of the oscillating fluid. At higher frequency, however, the steady stream transforms to a different shape in the tapered
tube, with transport in the divergent direction nearer the walls of the tube, rather than in the core. Transport by the continuing
streams with oscillatory ventilation of the respiratory tract should deliver medicinal aerosols of low intrinsic particle
mobility to the peripheral regions of the lungs. 相似文献

ObjectivesWith complex health technologies entering the market, methods for health technology assessment (HTA) may require changes. This study aimed to identify challenges in HTA of complex health technologies.MethodsA survey was sent to European HTA organizations participating in European Network for HTA (EUnetHTA). The survey contained open questions and used predefined potentially complex health technologies and 7 case studies to identify types of complex health technologies and challenges faced during HTA. The survey was validated, tested for reliability by an expert panel, and pilot tested before dissemination.ResultsA total of 22 HTA organizations completed the survey (67%). Advanced therapeutic medicinal products (ATMPs) and histology-independent therapies were considered most challenging based on the predefined complex health technologies and case studies. For the case studies, more than half of the reported challenges were “methodological,” equal in relative effectiveness assessments as in cost-effectiveness assessments. Through the open questions, we found that most of these challenges actually rooted in data unavailability. Data were reported as “absent,” “insufficient,” “immature,” or “low quality” by 18 of 20 organizations (90%), in particular data on quality of life. Policy and organizational challenges and challenges because of societal or political pressure were reported by 8 (40%) and 4 organizations (20%), respectively. Modeling issues were reported least often (n = 2, 4%).ConclusionsMost challenges in HTA of complex health technologies root in data insufficiencies rather than in the complexity of health technologies itself. As the number of complex technologies grows, the urgency for new methods and policies to guide HTA decision making increases. 相似文献

ObjectivesTo explore the use of data dashboards to convey information about a drug’s value, and reduce the need to collapse dimensions of value to a single measure.MethodsReview of the literature on US Drug Value Assessment Frameworks, and discussion of the value of data dashboards to improve the manner in which information on value is displayed.ResultsThe incremental cost per quality-adjusted life-year ratio is a useful starting point for conversation about a drug’s value, but it cannot reflect all of the elements of value about which different audiences care deeply. Data dashboards for drug value assessments can draw from other contexts. Decision makers should be presented with well-designed value dashboards containing various metrics, including conventional cost per quality-adjusted life-year ratios as well as measures of a drug’s impact on clinical and patient-centric outcomes, and on budgetary and distributional consequences, to convey a drug’s value along different dimensions.ConclusionsThe advent of US drug value frameworks in health care has forced a concomitant effort to develop appropriate information displays. Researchers should formally test different formats and elements. 相似文献

BackgroundHypertension is mainly managed in primary care. Shared decision making is widely recommended as an approach to treatment decision making. However, no studies have investigated; in detail, what happens during primary care consultations for hypertension.AimTo understand patients’ and clinicians’ experience of shared decision making for hypertension in primary care, in order to propose how it might be better supported.DesignLongitudinal qualitative study.SettingFive general practices in south‐west England.MethodInterviews with a purposive sample of patients with hypertension, and with the health‐care practitioners they consulted, along with observations of clinical consultations, for up to 6 appointments. Interviews and consultations were audio‐recorded and observational field notes taken. Data were analysed thematically.ResultsForty‐six interviews and 18 consultations were observed, with 11 patients and nine health‐care practitioners (five GPs, one pharmacist and three nurses). Little shared decision making was described by participants or observed. Often patients’ understanding of their hypertension was limited, and they were not aware there were treatment choices. Consultations provided few opportunities for patients and clinicians to reach a shared understanding of their treatment choices. Opportunities for patients to engage in choices were limited by structured consultations and the distribution of decisions across consultations.ConclusionFor shared decision making to be better supported, consultations need to provide opportunities for patients to learn about their condition, to understand that there are treatment choices, and to discuss these choices with clinicians.Patient or Public ContributionA patient group contributed to the design of this study. 相似文献

The COVID-19 pandemic has had a major impact on nursing homes (NHs), which were not prepared to manage infections among their at-risk patient populations. In order to comply with the French government's guidelines, we rapidly set up a local support platform (LSP) to help NHs manage their cases of COVID-19. The LSP comprised multidisciplinary decision support, a specialist phone hotline, mobile geriatric medicine teams, and videoconferences on COVID-19.We first quantified the LSP's interventions in 63 local NHs since the start of the first wave of COVID-19 (March 2020): 9 instances of multidisciplinary decision support, 275 calls to the specialist phone hotline, 84 interventions by mobile geriatric medicine teams, and 16 videoconferences. The LSP had been used during and between the first and second waves of the epidemic, and all had evolved to meet the NHs' needs. 相似文献
