Economic aspects of pharmacotherapy for chronic constipation

Constipation is one of the most common digestive complaints. It is a symptom, not a disease. The subjectivity that this involves means that assessments of clinical epidemiology, socioeconomic costs and pharmacotherapy are difficult, since there is no definition of 'normal' bowel habit. Although constipation can affect all ages, the problem increases with age, and is of particular concern for those who are frail and in long term care. Cultural influences may affect the prevalence in older people. Drug therapy of constipation cannot be considered in isolation, since there are issues in the prevention of constipation and the principles of good management that also apply. Furthermore, some consideration of the pathophysiology and diagnosis is important. This is because a number of remediable causes can be identified, and the diagnostic process involves patient education, which in turn may be effective in reducing costs. It is the complaint of constipation which leads either to self-medication or to consultation with the medical profession. Both of these courses of action have a significant influence on utilisation of laxatives (cathartics), obtained both over-the-counter and by prescription. Although there are a large number of laxative preparations available, therapy has changed little in half a century. Costs may vary considerably, and with such a significant problem there is a need for comparative studies. However, study methodologies are difficult, and a significant placebo response may be found. Education and preventive measures have been shown to reduce laxative use and costs in institutions. Unfortunately, there are few comparative studies of individual laxatives and even fewer cost-effectiveness studies. Those that there are have been based in institutions, and so extrapolation to other situations may be difficult. In general, little attention is given to constipation. It is, however, an area with significant resource implications in which education and preventive measures have been shown to be beneficial. Even so, there is still a need for good comparative studies, particularly where cost effectiveness is concerned.

Veiled Aspects of Bach Reception in the Long Nineteenth Century Exposed through a Macro-examination of Printed Music: with Particular Focus on The Well-Tempered Clavier

It presents questions that have arisen as a result of more than 20 years of collecting the data for the Bach Bibliography. Taking editions of The Well-Tempered Clavier as an example and using figures and graphs extracted from the Bach Bibliography, Tomita explores the various facets of the work's reception including its market appeal, the ambitions that steered its editors and publishers, and trends in its interpretation.

A study of the relational aspects of the culture of academic medicine

PURPOSE: The impact of medical school culture on medical students has been well studied, but little documentation exists regarding how medical faculty experience the culture in which they work. In an ongoing project, the National Initiative on Gender, Culture and Leadership in Medicine, the authors are investigating how the existing culture of academic medical institutions supports all faculty members' ability to function at their highest potential. METHOD: The authors conducted a qualitative study of faculty in five disparate U.S. medical schools. Faculty in different career stages and diverse specialties were interviewed regarding their perceptions and experiences in academic medicine. Analysis was inductive and data driven. RESULTS: Relational aspects of the culture emerged as a central theme for both genders across all career categories. Positive relationships were most evident with patients and learners. Negative relational attributes among faculty and leadership included disconnection, competitive individualism, undervaluing of humanistic qualities, deprecation, disrespect, and the erosion of trust. CONCLUSIONS: The data suggest that serious problems exist in the relational culture and that such problems may affect medical faculty vitality, professionalism, and general productivity and are linked to retention. Efforts to create and support trusting relationships in medical schools might enhance all faculty members' efforts to optimally contribute to the clinical, education, and research missions of academic medicine. Future work will document the outcomes of a five-school collaboration to facilitate change in the culture to support the productivity of all medical faculty. © 2009 Association of American Medical Colleges.

Infection systems biology:from reactive to proactive (P4) medicine

This short review establishes the conceptual bases and discusses the principal aspects of P4-shorthand for predictive, preventive, personalized and participatory medicine-medicine, in the framework of infectious diseases. P4 medicine is a new way to approach medical care; instead of acting when the patient is sick, physicians will be able to detect early warnings of disease to take early action. Furthermore, people might even be able to adjust their lifestyles to prevent disease. P4 medicine is fuelled by systems approaches to disease, including methods for personalized genome sequencing and new computational techniques for building dynamic disease predictive networks from massive amounts of data from a variety of OMICs. An excellent example of the effectiveness of the P4 medicine approach is the change in cancer treatments. Emphasis is placed on early detection, followed by genotyping of the patient to use the most adequate treatment according to the genetic background. Cardiovascular diseases and perhaps even neurodegenerative disorders will be the next targets for P4 medicine. The application of P4 medicine to infectious diseases is still in its infancy, but is a promising field that will provide much benefit to both the patients and the health-care system.

Positive aspects and challenges associated with caring for a dying relative at home

Research has consistently shown that family caregivers have a variety of unmet needs, despite comprehensive professional support for caregivers being a central aim of palliative care. This sub-study of a larger randomized controlled trial sought feedback from 47 primary family caregivers of advanced cancer patients who had recently commenced home palliative care. During semi-structured interviews in their homes, family caregivers were asked to comment on the key challenges associated with their role and whether they could identify challenges. These were associated with their own ill health, family circumstances, insufficient skills to manage patient symptoms, limited time for themselves and inadequate support from health professionals. Despite these challenges, 60% of family caregivers were readily able to identify positive aspects of the role. Previous research has tended to focus on the negative impact of caregiving. The extent to which the positive aspects buffer the negative aspects of the role warrants further exploration, as does the long-term impact of the caregiver role on those who are unable to recognize positive elements.

Safe eye surgery: non-technical aspects

The traditional training of surgeons focused exclusively on developing knowledge, clinical expertise, and technical (surgical) skills. However, analyses of the reasons for adverse events in surgery have revealed that many underlying causes originate from behavioural or non-technical aspects of performance (eg, poor communication among members of the surgical team) rather than from a lack of surgical (ie, technical) skills. Therefore, technical skills appear to be necessary but not sufficient to ensure patient safety. Paying attention to non-technical skills, such as team working, leadership, situation awareness, decision making, and communication, will increase the likelihood of maintaining high levels of error-free performance. Identification and training of non-technical skills has been developed for high-risk careers, such as civil aviation and nuclear power. Only recently, training in non-technical skills has been adopted by the surgical world and anaesthetists. Non-technical skills need to be tailored to the environment where they are used, and eye surgery has some substantial differences compared with other surgical areas, for example, high volume of surgery, use of local anaesthetics, and very sophisticated equipment. This review highlights the need for identification of the non-technical skills relevant to eye surgeons and promotion of their use in the training of eye surgeons.

Catalytic conversion of sodium lignosulphonate to vanillin –engineering aspects. Part 1 Effect of processing conditionson vanillin yield and selectivity

The commercial production of vanillin from sodium lignosulfonate under highly alkaline conditions, catalyzed by Cu2+ at elevated temperature and pressures up to 10 bar, has been simulated in a 3-L stirred reactor. Initially, the process was operated in the presence of nitrogen in dead-end mode, and it was shown that vanillin and vanillic acid were formed by hydrolysis at temperatures of 120, 140, and 160 °C. At the two higher temperatures, the amount of vanillin produced was the same. Subsequently, experiments were conducted at the same elevated pressures and temperatures with addition of air or oxygen-enriched air once the temperature in the reactor had reached temperatures similar to those used when only hydrolysis occurred. In this case, the concentration of vanillin at 140 and 160 °C was equal to that due to hydrolysis, and the subsequent 2-fold increase was due to oxidation. In addition, both vanillic acid and acetovanillone (which has rarely been reported) were produced, as was hydrogen. Thus, for the first time, it has been shown that the production of vanillin (and other compounds) from sodium lignosulfonate at elevated temperatures involves hydrolysis and oxidation, with hydrolysis starting at just above 100 °C, that is, much lower than has previously been reported. Approximately 50% is produced by each mechanism. In addition, the orders of the reactions of the different steps were estimated, and the reaction mechanisms are discussed.
