The N-of-1 trial: the ideal study design that is underused

The randomised experiment in a single patient, the N-of-1 trial, is the best study design for demonstrating causality, for example between agent and effect. Despite this, this type of study is only encountered sporadically in medical journals. One reason for this is that even this type of design cannot definitively demonstrate causality, because different points in time are compared with one another. Moreover, the design is rather inefficient, since the results correspond with those from observation without randomisation, placebo control or blinding. Even so, the N-of-1 trial is the ultimate form of verification in, for example, the individualisation of treatment. For this reason, this form of study might be used more often.     

Maternal-infant bonding and the mother's participation during venipuncture: a psychoanalytic perspective

Professionals discuss accompanying mothers' participation during painful procedures as a possibility of care to mother and child, but there is no consensus on this subject. To contribute to this topic, this study addresses the child's needs during venipuncture in a hospital environment and the mother's participation in this procedure, based on authors from psychoanalysis and mother-child bonding.     

Care for Nurses Only? Medicine and the Perceiving Eye

In this paper I introduce a theoretical framework on care developed by the Norwegian nurse and philosopher Kari Martinsen, and I argue that this approach has relevance not only within nursing, but also within clinical medicine. I try to substantiate this claim by analysing some of the key concepts in this approach, and I illustrate the potential clinical relevance of this approach by applying it in relation to two care scenarios. Finally, I discuss some of the concerns that have been raised in relation to the aim of highlighting care in medicine.     

Has consultation achieved its primary prevention potential?

Since the practice of consultation first began, primary prevention has been posited as an important outcome. In this article the empirical basis for this element of consultation is examined. It is concluded that consultation's preventive benefits should not be oversold, as at this time there is only emerging evidence for this aspect of the process.     

The SARS-CoV nucleocapsid protein: a protein with multifarious activities.

Ever since the discovery of SARS-CoV in the year 2003, numerous researchers around the world have been working relentlessly to understand the biology of this virus. As in other coronaviruses, nucleocapsid (N) is one of the most crucial structural components of the SARS-CoV. Hence major attention has been focused on characterization of this protein. Independent studies conducted by several laboratories have elucidated significant insight into the primary function of this protein, which is to encapsidate the viral genome. In addition, many reports also suggest that this protein interferes with different cellular pathways, thus implying it to be a key regulatory component of the virus too. In the first part of this review, we will discuss these different properties of the N-protein in a consolidated manner. Further, this protein has also been proposed to be an efficient diagnostic tool and a candidate vaccine against the SARS-CoV. Hence, towards the end of this article, we will discuss some recent progress regarding the possible clinically relevant use of the N-protein.     

The consolidation of private health plans in Brazil: challenges for the regulator

The effects of the financial consolidation of Brazil's private health plan market warrants investigation, as this trend could enhance the power of large plans and affect the financing of the National Health System. From the standpoint of the political economics of this sector, while reflecting on the features of this consolidation, this paper discusses whether this more powerful market clout might require the State to adopt a more active stance, especially if it wishes to enforce the normative principles of the National Supplementary Health Regulator in order to protect consumers, ensure regulated competition and defend the public interest.     

The borders of health promotion—A response to nordenfelt

Nordenfelt has presented a very useful philosophical analysis of the nature and ethics of health promotion. The first section of this paper is a response to the starting point of that analysis—the equation of health promotion with health promotion action. It is argued that this starting point leads to a serious ambiguity, and that this ambiguity is characteristic of other writing about health promotion, including that of the WHO. The second section of this paper explores the implications of this ambiguity, as it appears in the wider health promotion literature, for drawing the borders of health promotion.     

The commodification of American health care

Since 1980, cost containment efforts have radically transformed the delivery of medical services in the United States. The number and diversity of private, for-profit delivery systems have significantly increased and so has the competition among them. Some Marxists have conceptualized these changes as a transition from a non-commodity to a commodity form of medical care. They have labeled this the process of 'commodification' of medical services. However, this paper demonstrates that this process took place over 50 years ago. In light of this historical finding, an alternative Marxian analysis of the current medical conjuncture is briefly presented. Several of the key attractions of this approach are discussed.
