Konsumerismi, potilaiden ja kuluttajien aktiivinen toiminta sekä erityisesti lääkäreiden kokemukset ja näkemykset potilaista kuluttajina

Consumerism emphasises the patient s position and freedom of choice. Consumerism is being promoted by a range of phenomena occurring in society and health care. Different actors hold different views on the patient as a consumer and on his or her participation. Consumer demand is created outside the patient physician relationship and the commercialisation of services generates new expectations with respect to physician s work. More and more patients may be interested in adopting a more equal position in the care relationship, and trying to negotiate with the physician or to even dictate how he or she should be cared for. In Finland, very little research has been conducted on patients and consumers organising themselves at national system level, patients as choosers, and physicians attitudes to various consumerist phenomena or the choice made by the patient. In the empirical data for this study, the term consumer-patient refers to active consumers and patients making choices related to their clinical care prior to a physician s diagnosis. Consumer-patients are also represented by consumer and patient organisations and movements. The main research question is: How do physicians regard the care choice made by the patient? This question is addressed from a perspective encompassing patients and consumers organised activities and individuals active behaviour in health care as well as physicians experiences and their views on patients as consumers making choices related to their care. The first part (Study I), examines the patient organisation field, information sources used including the websites of such organisations, files from Finland s Slot Machine Association, RAY, a survey conducted by a Finnish television news department and interviews of patient organisations. Based on observation and a physician survey, Study II examines physicians attitudes to the idea that patients could obtain information through consumer movements about physicians care practices before seeking medical care. Studies III−IV use a physician survey to examine physicians attitudes to direct-to-consumer-advertising of prescription drugs (DTCA) and their experiences and views of patient requests related to treatments and examinations. Study V uses comparative surveys to examine the attitudes of health care professionals and the population to the introduction of new technologies in health care, using genetic screenings and tests as an example. The number of patient organisations increased, with a particular escalation as of the 1990s. The characteristics and operating methods of the organisations varied greatly. Physicians organisations adopted a negative or neutral attitude towards the consumer movements idea of distributing information on care practices, whereas individual physicians attitudes were slightly more positive. Physicians regarded direct-to-consumer-advertising of prescription drugs as negative, but took a more permissive attitude towards indirect advertising. More than every third physician considered drug advertisements in general to be harmful or useless in the distribution of drug information to patients or consumers. More than half of physicians conducting patient work reported that they (very) often encountered patients who stated upon arrival for a consultation that they wanted specific treatments or examinations, and that the number of such situations had increased. Such situations were viewed as positive with regard to the care relationship by every fifth physician and as negative by two fifths. Physicians justified a reserved attitude to the patients consumer role by referring to their medical expertise and position as care decision-makers, the patient physician relationship and the public health care system. Reasons for a positive attitude included the patient s participation and co-operation, the patient physician relationship and the patient s knowledge. Professionals were more reserved than lay people about the introduction and extension of genetic technologies in health care. A significant minority of the physicians did not take a clear pro or con attitude to the patients consumer role or to the use of new technologies in health care. The physicians age, gender, place of work and specialisation influenced their attitudes to the patient s consumer role, and private physicians viewed it in a more positive light than those working in public health care. Active consumer-patients challenge the society to hold a discussion of the patient s choice, participation in care decision-making and participation in health care policy in general. Their transformation into customers and consumers implies not only a new division of individuals roles and powers, but also contributes to changing relationships between system level roles: between citizens and the state and between public and private health care. This phenomenon raises various issues related to health care policy. In conclusion, topics are presented for discussion, practical measures and further research. Keywords: health care, consumerism, distribution of technologies, commercialisation, physicians, patients, consumers, patient s choice, patient s role.

Regulation of cytochrome P-450 gene expression. Studies with a cloned probe

A cDNA clone for cytochrome P-450e, a phenobarbitone-inducible species in rat liver, has been isolated and characterized. With the use of this cloned DNA, an attempt has been initiated to elucidate the factors regulating the cytochrome P-450 gene expression. Inhibitors of heme synthesis such as cobalt chloride and 3-amino-1,2,4-triazole block the induction of cytochrome P-450e by phenobarbitone at the level of transcription. This is evident from the decrease in the rate of synthesis of cytochrome P-450e, a decrease in the levels of specific translatable messenger RNA, a decrease in the specific cytoplasmic and nuclear messenger RNA contents, and nuclear transcription of cytochrome P-450e gene, as revealed by hybridization to the cloned probe, under these conditions. It is proposed that heme is a general regulator of cytochrome P-450 gene expression at the level of transcription, whereas the drug or its metabolite would impart the specificity needed for the induction of a particular species.

On the functional ordering of biomembranes : Implications for drug binding

Cells are packed with membrane structures, defining the inside and outside, and the different subcellular compartments. These membranes consisting mainly of phospholipids have a variety of functions in addition to providing a permeability barrier for various compounds. These functions involve cellular signaling, where lipids can act as second messengers, or direct regulation of membrane associating proteins. The first part of this study focuses on relating some of the physicochemical properties of membrane lipids to the association of drug compounds to membranes. A fluorescence based method is described allowing for determination of the membrane association of drugs. This method was subsequently applied to a novel drug, siramesine, previously shown to have anti-cancer activity. Siramesine was found to associate with anionic lipids. Especially interesting is its strong affinity for a second messenger lipid phosphatidic acid. This is the first example of a small molecule drug compound specifically interacting with a cellular lipid. Phosphatidic acid in cells is required for the activation of many signaling pathways mediating growth and proliferation. This provides an intriguing possibility for a simple molecular mechanism of the observed anti-cancer activity of siramesine. In the second part the thermal behavior and self assembly of charged and uncharged membrane assemblies was studied. Strong inter-lamellar co-operativity was observed for multilamellar DPPC vesicles using fluorescence techniques together with calorimetry. The commonly used membrane models, large unilamellar vesicles (LUV) and multilamellar vesicles (MLV) were found to possess different biophysical properties as interlamellar interactions of MLVs drive segregation of a pyrene labeled lipid analogue into clusters. The effect of a counter-ion lattice on the self assembly of a cationic gemini surfactant was studied. The presence of NaCl strongly influenced the thermal phase behavior of M-1 vesicles, causing formation of giant vesicles upon exceeding a phase transition temperature, followed by a subsequent transition into a more homogenous dispersion. Understanding the underlying biophysical aspects of cellular membranes is of fundamental importance as the complex picture of the structure and function of cells is evolving. Many of the cellular reactions take place on membranes and membranes are known to regulate the activity of many peripheral and intergral membrane associating proteins. From the point of view of drug design and gene technology, membranes can provide an interesting target for future development of drugs, but also a vehicle sensitive for environmental changes allowing for encapsulating drugs and targeting them to the desired site of action.

There is 'hope for you yet': The female drug offender in sentencing discourse

Language and gender research has, in recent years, emphasised the importance of examining the context-specific ways in which people ‘do gender’ in different situations. In this paper, we explore how women involved in drug offences, specifically methamphetamine manufacture offences, are constructed within the language of the courts. Thirty-six sentencing transcripts from the New Zealand courts were examined to investigate how such offences, committed by women, are understood. In order to explore the representation of female offenders, a critical discourse analytic approach was adopted. Such an approach recognises that linguistic modes not only create and legitimise power inequalities but also embody a specific worldview. Three gendered discourses were identified in the sentencing texts: (i) the discourse of femininity, reinforcing the socially prescribed female role; (ii) the discourse of aberration, concerning women who breach traditional gender role expectations, and; (iii) the discourse of salvation, presenting aberrant women with an opportunity to become ‘good’ women once again. The findings illustrate the ways in which processes of gendering take place within a specific community of practice: the courtroom.

Age-related changes in hepatic function: An update on implications for drug therapy

The accumulation of deficits with increasing age results in a decline in the functional capacity of multiple organs and systems. These changes can have a significant influence on the pharmacokinetics and pharmacodynamics of prescribed drugs. Although alterations in body composition and worsening renal clearance are important considerations, for most drugs the liver has the greatest effect on metabolism. Age-related change in hepatic function thereby causes much of the variability in older people’s responses to medication. In this review, we propose that a decline in the ability of the liver to inactivate toxins may contribute to a proinflammatory state in which frailty can develop. Since inflammation also downregulates drug metabolism, medication prescribed to frail older people in accordance with disease-specific guidelines may undergo reduced systemic clearance, leading to adverse drug reactions, further functional decline and increasing polypharmacy, exacerbating rather than ameliorating frailty status. We also describe how increasing chronological age and frailty status impact liver size, blood flow and protein binding and enzymes of drug metabolism. This is used to contextualise our discussion of appropriate prescribing practices. For example, while the general axiom of ‘start low, go slow’ should underpin the initiation of medication (titrating to a defined therapeutic goal), it is important to consider whether drug clearance is flow or capacity-limited. By summarising the effect of age-related changes in hepatic function on medications commonly used in older people, we aim to provide a guide that will have high clinical utility for practising geriatricians.

High-level coordination and strategy in the 2007 equine influenza outbreak response.

The equine influenza (EI) outbreak presented many challenges that required high-level coordination and decision making, as well as the development of new approaches for satisfactory and consistent resolution. This paper outlines the elements of the national coordination arrangements, preparatory arrangements in place prior to the outbreak that facilitated national coordination, and some of the issues faced and resolved in the response.

Studies on immune activation in rheumatoid arthritis and reactive arthritis

Rheumatoid arthritis (RA) is an autoimmune disease characterized by synovitis, progressive joint destruction, and disability. Reactive arthritis (ReA) is a sterile joint inflammation following a distant mucosal infection. The clinical course of these diseases is variable and cannot be predicted with reasonable accuracy by clinical and laboratory markers. The predictive value of circulating soluble interleukin-2 receptor (sIL-2R), a marker of lymphocyte activation, measured by Immulite® automated immunoassay analyzer, was evaluated in two cohorts of RA patients. In 175 patients with active early RA randomized to treatment with either on disease-modifying antirheumatic drug (DMARD) or a combination of 3 DMARDs and prednisolone, low baseline sIL-2R level predicted remission after 6 months in patients treated with a single DMARD. In 24 patients with active RA refractory to DMARDs, low baseline sIL-2R level predicted rapid clinical response to treatment with infliximab, an anti-tumour necrosis factor antibody. Furthermore, in a cohort of 26 patients with acute ReA, high baseline sIL-2R level predicted remission after 6 months. Levels of circulating soluble E-selectin (sE-selectin), a marker of endothelial activation, were measured annually by enzyme-linked immunosorbent assay (ELISA) in a cohort of 85 patients with early RA. During a five-year follow-up, sE-selectin levels were associated with activity and outcome of RA. The levels of neutrophil and monocyte CD11b/CD18 expression measured by flow cytometry, and circulating levels of sE-selectin measured by ELISA, and procalcitonin by immunoluminometric assay, were compared in 28 patients with acute ReA and 16 patients with early RA. The levels of the markers were comparable in ReA, RA, and healthy control subjects. In conlusion, sIL-2R may provide a new predictive marker in early RA treated with a single DMARD and refractory RA treated with infliximab. In addition, sIL-2R level predicts remission in acute ReA.

The level of FoxO1 and IL-15 in skeletal muscle, serum and synovial fluid in people with knee osteoarthritis: a case control study

Objectives Impaired muscle function is common in knee osteoarthritis (OA). Numerous biochemical molecules have been implicated in the development of OA; however, these have only been identified in the joint and serum. This study compared the expression of interleukin (IL-15) and Forkhead box protein-O1 (FoxO1) in muscle of patients with knee OA asymptomatic individuals, and examined whether IL-15 was also present in the joint and serum. Method Muscle and blood samples were collected from 19 patients with diagnosed knee OA and 10 age-matched asymptomatic individuals. Synovial fluid and muscle biopsies were collected from the OA group during knee replacement surgery. IL-15 and FoxO1were measured in the skeletal muscle. IL-15 abundance was also analysed in the serum of both groups and synovial fluid from the OA group. Knee extensor strength was measured and correlated with IL-15 and FoxO1 in the muscle. Results FoxO1 protein expression was higher (p=0.04), whereas IL-15 expression was lower (p=0.02) in the muscle of the OA group. Strength was also lower in the OA group, and was inversely correlated with FoxO1 expression. No correlation was found between IL-15 in the joint, muscle or serum. Conclusion Skeletal muscle, particularly the quadriceps, is affected in people with knee OA where elevated FoxO1 protein expression was associated with reduced muscle strength. While IL-15 protein expression in the muscle was lower in the knee OA group, no correlation was found between the expression of IL-15 protein in the muscle, joint and serum, which suggests that inflammation is regulated differently within these tissues.

The antihypertensive drug pindolol attenuates long-term but not short-term binge-like ethanol consumption in mice

Alcohol dependence is a debilitating disorder with current therapies displaying limited efficacy and/or compliance. Consequently, there is a critical need for improved pharmacotherapeutic strategies to manage alcohol use disorders (AUDs). Previous studies have shown that the development of alcohol dependence involves repeated cycles of binge-like ethanol intake and abstinence. Therefore, we used a model of binge-ethanol consumption (drinking-in-the-dark) in mice to test the effects of compounds known to modify the activity of neurotransmitters implicated in alcohol addiction. From this, we have identified the FDA-approved antihypertensive drug pindolol, as a potential candidate for the management of AUDs. We show that the efficacy of pindolol to reduce ethanol consumption is enhanced following long-term (12-weeks) binge-ethanol intake, compared to short-term (4-weeks) intake. Furthermore, pindolol had no effect on locomotor activity or consumption of the natural reward sucrose. Because pindolol acts as a dual beta-adrenergic antagonist and 5-HT1A/1B partial agonist, we examined its effect on spontaneous synaptic activity in the basolateral amygdala (BLA), a brain region densely innervated by serotonin- and norepinephrine-containing fibres. Pindolol increased spontaneous excitatory post-synaptic current frequency in BLA principal neurons from long-term ethanol consuming mice but not naïve mice. Additionally, this effect was blocked by the 5-HT1A/1B receptor antagonist methiothepin, suggesting that altered serotonergic activity in the BLA may contribute to the efficacy of pindolol to reduce ethanol intake following long-term exposure. Although further mechanistic investigations are required, this study demonstrates the potential of pindolol as a new treatment option for AUDs that can be fast-tracked into human clinical studies.
