Twelve weeks of protracted venous infusion of fluorouracil (5-FU) is as effective as 6 months of bolus 5-FU and folinic acid as adjuvant treatment in colorectal cancer.
We performed a multicentre randomised trial to compare the efficacy and toxicity of 12 weeks of 5-fluorouracil (5-FU) delivered by protracted intravenous infusion (PVI 5-FU) against the standard bolus regimen of 5-FU and folinic acid (5-FU/FA) given for 6 months as adjuvant treatment in colorectal cancer. A total of 716 patients with curatively resected Dukes' B or C colorectal cancer were randomised to 5-FU/FA (5-FU 425 mg m(-2) i.v. and FA 20 mg m(-2) i.v. bolus days 1-5 every 28 days for 6 months) or to PVI 5-FU alone (300 mg m(-2) day for 12 weeks). With a median follow-up of 19.8 months, 133 relapses and 77 deaths have been observed. Overall survival did not differ significantly (log rank P=0.764) between patients receiving 5-FU/FA and PVI 5-FU (3-year survival 83.2 vs 87.9%, respectively). Patients in the 5-FU/FA group had significantly worse relapse-free survival (RFS, log rank P=0.023) compared to those receiving PVI 5-FU (3-year RFS, 68.6 vs 80%, respectively). Grades 3-4 neutropenia, diarrhoea, stomatitis and severe alopecia were significantly less (P<0.0001) and global quality of life scores significantly better (P&<0.001) for patients in the PVI 5-FU treatment arm. In conclusion, infused 5-FU given over 12 weeks resulted in similar survival to bolus 5-FU and FA over a 6 month period, but with significantly less toxicity
Barriers and facilitators of effective self-management in asthma: systematic review and thematic synthesis of patient and healthcare professional views
Self-management is an established, effective approach to controlling asthma, recommended in guidelines. However, promotion, uptake and use among patients and health-care professionals remain low. Many barriers and facilitators to effective self-management have 25 been reported, and views and beliefs of patients and health care professionals have been explored in qualitative studies. We conducted a systematic review and thematic synthesis of qualitative research into self-management in patients, carers and health care professionals regarding self-management of asthma, to identify perceived barriers and facilitators associated with reduced effectiveness of asthma self-management interventions. Electronic databases and guidelines were searched systematically for qualitative literature that explored factors relevant to facilitators and barriers to uptake, adherence, or outcomes of self-management in patients with asthma. Thematic synthesis of the 56 included studies identified 11 themes: 1) partnership between patient and health care professional; 2) issues around medication; 3) education about asthma and its management; 4) health beliefs; 5) self-management interventions; 6) co-morbidities 7) mood disorders and anxiety; 8) social support; 9) non-pharmacological methods; 10) access to healthcare; 11) professional factors. From this, perceived barriers and facilitators were identified at the level of individuals with asthma (and carers), and health-care professionals. Future work addressing the concerns and beliefs of adults, adolescents and children (and carers) with asthma, effective communication and partnership, tailored support and education (including for ethnic minorities and at risk groups), and telehealthcare may improve how self-management is recommended by professionals and used by patients. Ultimately, this may achieve better outcomes for people with asthma
Understanding situated survey refusal: applying sensemaking and sensegiving to ethnostatistics
Mouth State Detection From Low-Frequency Ultrasonic Reflection
This paper develops, simulates and experimentally evaluates a novel method based on non-contact low frequency (LF) ultrasound which can determine, from airborne reflection, whether the lips of a subject are open or closed. The method is capable of accurately distinguishing between open and closed lip states through the use of a low-complexity detection algorithm, and is highly robust to interfering audible noise. A novel voice activity detector is implemented and evaluated using the proposed method and shown to detect voice activity with high accuracy, even in the presence of high levels of background noise. The lip state detector is evaluated at a number of angles of incidence to the mouth and under various conditions of background noise. The underlying mouth state detection technique relies upon an inaudible LF ultrasonic excitation, generated in front of the face of a user, either reflecting back from their face as a simple echo in the closed mouth state or resonating inside the open mouth and vocal tract, affecting the spectral response of the reflected wave when the mouth is open. The difference between echo and resonance behaviours is used as the basis for automated lip opening detection, which implies determining whether the mouth is open or closed at the lips. Apart from this, potential applications include use in voice generation prosthesis for speech impaired patients, or as a hands-free control for electrolarynx and similar rehabilitation devices. It is also applicable to silent speech interfaces and may have use for speech authentication
Better Prognosis of Multiple Sclerosis in Patients Who Experienced a Full-Term Pregnancy
âThereâs so much to itâ: the ways physiotherapy students and recent graduates experience practice
Health science courses aim to prepare students for the demands of their chosen profession by learning ways appropriate to that profession and the contexts they will work and live in. Expectations of what students should learn become re-contextualised and translated into entry-level curriculum, with students operating as a connection between what is intended and enacted in curriculum, and required in the real world. Drawing on phenomenology, this paper explores how students understand practiceâthe collective, purposeful knowing, doing and being of a communityâin entry-level physiotherapy programs. Ways of thinking and practising (WTP)âa framework attentive to the distinctive nature of a discipline, its values, philosophies and world-view (McCune and Hounsell in High Educ 49(3):255â289, 2005)âprovides the conceptual lens. Six themes describing how students see the WTP of physiotherapy practice emerged from the analysis: discovery of new knowledge; problem solving client related contexts; adopting a systems based approach to the body; contributing to a positive therapeutic alliance; developing a sense of self and the profession; and the organisation of the workforce. The study produces knowledge about practice by focusing on physiotherapy studentsâ experiences of disciplinary learning. Including students in educational research in this way is an approach that can help students realise their potential as part of a community of practice
