Clinical research must be understood to be the foundation of scientific medicine of the clinical type. But the essence of scientific clinical medicine remains a matter of profound confusion, even in clinical academia, and so does the essence of clinical research. The confusion now revolves, principally, around ‘clinical epidemiology’. We address clinical research in the meaning of quintessentially ‘applied’ clinical research, which we take to be the foundation of the scientific knowledge (...) base of clinical medicine, of gnosis (dia‐, etio‐, pro‐) in it. More specifically, we address the essence, priorities, and status quo of this research – and argue that the requisite theory of this is not a matter of ‘clinical epidemiology’ but of theory of clinical research endogenous to clinical (rather than epidemiological) academia.

Despite its phenomenal success since its inception in the early nineteen-nineties, the evidence-based medicine movement has not succeeded in shaking off an epistemological critique derived from the experiential or tacit dimensions of clinical reasoning about particular individuals. This critique claims that the evidence-based medicine model does not take account of tacit knowing as developed by the philosopher Michael Polanyi. However, the epistemology of evidence-based medicine is premised on the elimination of the tacit dimension from clinical judgment. This is (...) demonstrated through analyzing the dichotomy between clinical and statistical intuition in evidence-based medicine’s epistemology of clinical reasoning. I argue that clinical epidemiology presents a more nuanced epistemological model for the application of statistical epidemiology to the clinical context. Polanyi’s theory of tacit knowing is compatible with the model of clinical reasoning associated with clinical epidemiology, but not evidence-based medicine. (shrink)

In little more than a decade, the AIDS epidemic has exerted a profound effect on morbidity and mortality among young adults and children in many parts of the world. One of the more dramatic aspects of AIDS is that it seems to have arisen almost spontaneously as a new epidemic, spreading rapidly within at-risk populations in a way that is unprecedented for the serious infectious diseases of recent memory. Tuberculosis, on the other hand, had only recently been considered a disease (...) of historical importance but of diminishing relevance to current public health priorities, especially in industrialized countries. Over the past decade, however, and in parallel with the AIDS epidemic, there has been a resurgence of tuberculosis in many of the same populations most affected by HIV infection. This has had important implications for clinical practice, public health, and the development of appropriate health policy. A number of elements have converged to promote the development of HIV-related tuberculosis, including biologic, social, and environmental factors. These will be discussed both to provide a context for understanding the relationship between the two epidemics, and as a basis for suggesting strategies for tuberculosis control in the AIDS era.

Epidemiology is a science of disease which specifies rates (illness prevalences, incidences, distributions, etc.). Evolution is a science of life which specifies changes (gene frequencies, generations, forms, function, etc.). Evolutionary Epidemiology is a synthesis of these two sciences which combines the empirical power of classical methods in genetical epidemiology with the interpretive capacities of neo-darwinian evolutionary genetics. In particular, prevalence rates of genetical diseases are important data points when reformulated for the purpose of analysis in terms of (...) their evolutionary frequencies. Traits which exceedprevalences beyond the rates of mutation (in Hardy-Weinberg calculations) or evidence unusualrange of phenotypic reaction are of special interest. This is because traits which did not confer advantages in the environment of evolutionary adaptation cannot accede, through natural selection, to anything but low rates of genomic prevalence.Evolutionary epidemiology is, in all of medicine, of particular promise in ongoing efforts to better understand psychopathology. Many complexities of phenotypic adjustment arise when new developmental demands are placed on an old genome. The new and complex biosocial ecology of human mass society now evokes different phenotypes than those in the prehistorical ecology to which the genome is structurally and functionally better adapted. Some of these new phenotypes are darwinian failures. In this paper, the theoretical implications of evolutionary epidemiology are extended and some tentative points of clinical application (particularly to psychiatry) are offered. (shrink)

Staphylococcus aureus ST45 is a major global MRSA lineage with huge strain diversity and a high clinical impact. It is one of the most prevalent carrier lineages but also frequently causes severe invasive disease, such as bacteremia. Little is known about its evolutionary history. In this study, we used whole-genome sequencing to analyze a large collection of 451 diverse ST45 isolates from 6 continents and 26 countries. De novo-assembled genomes were used to understand genomic plasticity and to perform coalescent (...) analyses. The ST45 population contained two distinct sublineages, which correlated with the isolates’ geographical origins. One sublineage primarily consisted of European/North American isolates, while the second sublineage primarily consisted of African and Australian isolates. Bayesian analysis predicted ST45 originated in northwestern Europe about 500 years ago. Isolation time, host, and clinical symptoms did not correlate with phylogenetic groups. Our phylogenetic analyses suggest multiple acquisitions of the SCCmec element and key virulence factors throughout the evolution of the ST45 lineage. (shrink)

Since the 1970’s epidemiological measures focusing on “health-related quality of life” or simply “quality of life” have figured increasingly as endpoints in clinical trials. Before the 1970’s these measures were known, generically, as performance measures or health status measures. Relabeled as “quality of life measures” they were first used in cancer trials. In the early 2000’s they were relabeled again as “patient-reported outcome measures” or PROMs, in their service to the FDA to support drug labeling claims. To the limited (...) degree that the philosophical literature addresses these measures, it tends to associate them with two major theories of well-being: subjective well-being and the capabilities approach. In this paper, I argue that philosophers ought to treat quality of life measures/proms as a distinct from these theories. I argue that quality of life/proms serve healthcare as vehicles for patient-centered care and this has important consequences for how we theorize these measures. To this end, two requirements set them apart from measures of subjective well-being and the capabilities approach: quality of life/proms need to be patient-directed and inclusive. (shrink)

This book offers a philosophically-based, yet clinically-oriented perspective on current medical reasoning aiming at 1) identifying important forms of uncertainty permeating current clinical reasoning and practice 2) promoting the application of an abductive methodology in the health context in order to deal with those clinical uncertainties 3) bridging the gap between biomedical knowledge, clinical practice, and research and values in both clinical and philosophical literature. With a clear philosophical emphasis, the book investigates themes lying at the (...) border between several disciplines, such as medicine, nursing, logic, epistemology, and philosophy of science; but also ethics, epidemiology, and statistics. At the same time, it critically discusses and compares several professional approaches to clinical practice such as the one of medical doctors, nurses and other clinical practitioners, showing the need for developing a unified framework of reasoning, which merges methods and resources from many different clinical but also non-clinical disciplines. In particular, this book shows how to leverage nursing knowledge and practice, which has been considerably neglected so far, to further shape the interdisciplinary nature of clinical reasoning. Furthermore, a thorough philosophical investigation on the values involved in health care is provided, based on both the clinical and philosophical literature. The book concludes by proposing an integrative approach to health and disease going beyond the so-called “classical biomedical model of care”. (shrink)

Since the second half of the twentieth century, biomedical research has made increasing use of epidemiological methods to establish empirical evidence on a population level. This paper is about practices with data in epidemiological research, based on a case study in Denmark. I propose an epistemology of record linkage that invites exploration of epidemiological studies as heterogeneous assemblages. Focusing on data collecting, sampling and linkage, I examine how data organisation and processing become productive beyond the context of their collection. The (...) case study looks at how a local population database established in 1976 to investigate possibilities for the prevention of cardiovascular disease is used thirty years later to test hypotheses on the aetiology of breast cancer. For two breast cancer investigations based on the same core data set, I follow the underlying record linkage practice and describe how research objects such as molecular markers become relevant with respect to public health through information networking. Epidemiological association studies function as tools that performatively enrol different contexts into statistical risk estimation, thereby configuring options for research as well as for clinical testing and public health policy.

With the aim of ascertaining if child-to-parent offenders have impairments in the executive functions and psychological maladjustment, and to quantify the potential harm and epidemiology, a field study was designed. As for this, 76 juvenile offenders sentenced for child-to-parent violence were assessed in executive functions and psychological adjustment. The results showed valid responses for 75 juveniles and that data were not generally biased in line with defensiveness or malingering. In psychological adjustment, the results revealed a significantly higher maladjustment among (...) offenders on all the basic clinical scales with 23% more symptoms of hysteria than the normative population, 37% more of depressive symptoms, 44% more of hypochondriac symptoms, 68% more of psychopathic deviation symptoms, 46% more of paranoid symptoms, 26% more of psychasthenic symptoms, 24% more symptoms of schizophrenia, 17% more symptoms of hypomania, and 13% more symptoms of social introversion. Epidemiologically, the prevalence rates of clinical deterioration were significantly greater than expected in hypochondria, depression, hysteria, psychopathic deviation, paranoia, psychasthenia, and schizophrenia. As for the cognitive functions, the offenders exhibited impairments estimated at 62.0% in word reading, 47.9% in color naming, 45.8% in color-word, and 11.9% in interference and a significantly higher prevalence of caseness than expected in word reading, color naming, and color-word. The implications of the results for intervention are discussed. (shrink)

This paper reassesses Robert Koch’s work on tropical infections of humans and cattle as being inspired by an underlying interest in epidemiology. Such an interest was developed from the early 1890s when it became clear that an exclusive focus on pathogens was insufficient as an approach to explain the genesis and dynamics of epidemics. Koch, who had failed to do so before, now highlighted differences between infection and disease and described the role of various sub-clinical states of disease (...) in the propagation and—consequently—in the control of epidemics. Studying pathologies of men and cattle in tropical countries eventually facilitated the application of such measures in Europe through the screening of healthy carriers of typhoid, which was carried out in 1902. The concept of the carrier state can be understood as a spin-off from tropical medicine into the study and control of infectious disease in Europe. With it travelled assumptions that were typical for colonial and veterinary medicine where the health of indigenous individuals or cattle would be a secondary objective compared to the control of diseases in populations.

Therapeutic reactivity among psychology trainees was ascertained by their response to 10 clinical vignettes depicting clients with HIV who are sexually active with uninformed partners. This construct accounts for the relative change in decisions to maintain the confidentiality of clients who acknowledge safe versus unsafe sexual behavior. As anticipated, an analysis of variance revealed a significant main effect for safety and a significant 3-way interaction. Subsequent analyses revealed that trainees exhibit the highest level of therapeutic reactivity toward heterosexual male (...) clients, and the lowest reactive stance toward heterosexual female clients. Although the decisional pattern evidenced toward heterosexuals seems congruent with epidemiological estimates of risk, the decisions toward lesbians and gay males appear more likely a function of bias. The ethical implications of these findings are discussed. (shrink)

Since the late 1980s, the fetal origins of adult disease, from 2003 developmental origins of health and disease (DOHaD), has stimulated significant interest in and an efflorescence of research on the long-term effects of the intrauterine environment. From the start, this field has been interdisciplinary, using experimental animal, clinical and epidemiological tools. As the influence of DOHaD on public health and policy expanded, it has drawn criticism for reducing the complex social and physical world of early life to women’s (...) reproductive bodies as drivers of intergenerational ills. This paper explains this narrowing of focus in terms of a formative and consequential exchange between David Barker, the British epidemiologist whose work is credited with establishing the field, and the discipline of fetal physiology. We suggest that fetal physiologists were a crucial constituency of support for Barker’s hypothesis about early life origins of disease. Their collaborations with Barker helped secure and sustain the theory amid considerable controversy. The trajectory of DOHaD and its focus on the maternal body can be understood, we argue, as a consequence of this alliance, which brought together two distinct conceptualizations of the intrauterine environment, one from epidemiology and the other from fetal physiology. Along the way, we trace the histories of these conceptualizations, both of which were products of mid-to-late twentieth century British science, and show how Barker’s early emphasis on social and economic conditions was superseded by a narrower focus on physiological mechanisms acting upon the autonomous fetus.

Available from UMI in association with The British Library. ;This thesis traces endeavours in the twentieth century to provide the 'intellectual' foundations for general medical practice as an independent, autonomous clinical discipline. The empirical focus of the study is upon the application of psychological and 'person-centred' approaches to general practice; above all, in the work of Michael Balint, and the Royal College of General Practitioners in the post-war period. The thesis is guided by two predominant theoretical concerns. First, to (...) highlight the complex strategies and the wide range of means and resources that have been required to give substance to the claim that general practice is 'by nature' a person-centred endeavour. Second, to consider--and to question--certain influential approaches to medical power in general, and to the social consequences of 'emancipatory'--person-centred--forms of medicine in particular. Specifically, the 'power/knowledge' approach to medical sociology is contested both with regard to its empirical findings and in relation to its basis in the work of Michel Foucault . ;The study which follows is intended neither as a narrative history of general practice nor as a history of ideas about general practice. Its empirical concern is more specific than either of these. Focusing upon the twentieth century and above all the post-war period, it seeks to analyse some of the ways in which general practitioners have sought to autonomise their discipline by giving it an 'intellectual' basis. If the 'general practitioner' has long existed as a professional label then nevertheless notions of what unifies the general practitioner's activities have undergone a degree of mutation. It is these 'models' of general practice--physiological, epidemiological, psychological--which will be investigated here. As such, the purpose behind the study is partly of a 'methodological' order. The study seeks to show that what counts in evolving a coherent model of general practice is not just the provision of a 'representation' of the general practitioner's activities but a construction on several levels.

During the set-up phase of an international study of genetic influences on outcomes from sepsis, we aimed to characterise potential differences in ethics approval processes and outcomes in participating European countries. Between 2005 and 2007 of the FP6-funded international Genetics Of Sepsis and Septic Shock project, we asked national coordinators to complete a structured survey of research ethic committee approval structures and processes in their countries, and linked these data to outcomes. Survey findings were reconfirmed or modified in 2017. Eighteen (...) countries participated in the study, recruiting 2257 patients from 160 ICUs. National practices differed widely in terms of composition of RECs, procedures and duration of the ethics approval process. Eight countries used a single centralised process for approval, seven required approval by an ethics committee in each participating hospital, and three required both. Outcomes of the application process differed widely between countries because of differences in national legislation, and differed within countries because of interpretation of the ethics of conducting research in patients lacking capacity. The RECs in four countries had no lay representation. The median time from submission to final decision was 1.5 months; in nine approval was received within 1 month; six took over 6 months, and in one 24 months; had all countries been able to match the most efficient approvals processes, an additional 74 months of country or institution-level recruitment would have been available. In three countries, rejection of the application by some local RECs resulted in loss of centres; and one country rejected the application outright. The potential benefits of the single application portal offered by the European Clinical Trials Regulation will not be realised without harmonisation of research ethics committee practices as well as national legislation.

Traumatic experiences and post-traumatic stress are highly prevalent in people with psychosis, increasing symptom burden, decreasing quality of life and moderating treatment response. A range of post-traumatic sequelae have been found to mediate the relationship between trauma and psychotic experiences, including the “traditional” symptoms of post-traumatic stress disorder. The International Classification of Diseases-11th Edition recognizes a more complex post-traumatic presentation, complex PTSD, which captures both the characteristic symptoms of PTSD alongside more pervasive post-traumatic sequelae known as ‘disturbances in self-organization’. The (...) prevalence and impact of cPTSD and DSOs in psychosis remains to be explored. In the first study of this kind, 144 participants with psychosis recruited from North West United Kingdom mental health services completed measures assessing trauma, PTSD and cPTSD symptoms and symptoms of psychosis. Forty-percent of the sample met criteria for cPTSD, compared to 10% who met diagnostic criteria for PTSD. PTSD and DSOs mediated the relationship between trauma and positive symptoms, controlling for dataset membership. Both PTSD and DSOs mediated the relationship between trauma and affective symptoms but did not explain a significant proportion of variance in negative symptoms. Cognitive and excitative symptoms of psychosis did not correlate with trauma, PTSD or DSO scores. These findings indicate the possible value of adjunct therapies to manage cPTSD symptoms in people with psychosis, pending replication in larger epidemiological samples and longitudinal studies.

The relation between biomedical knowledge and clinicalknowledge is discussed by comparing their respectivestructures. The knowledge of a disease as a biologicalphenomenon is constructed by the interaction of factsand theories from the main biomedical disciplines:epidemiology, diagnostics, clinical trial, therapydevelopment and pathogenesis. Although these facts andtheories are based on probabilities andextrapolations, the interaction provides a reliableand coherent structure, comparable to a Kuhnianparadigma. In the structure of clinical knowledge,i.e. knowledge of the patient with the disease, notonly biomedical knowledge contributes to (...) the structurebut also economic and social relations, ethics andpersonal experience. However, the interaction betweeneach of the participating ``knowledges'' in clinicalknowledge is not based on mutual dependency andaccumulation of different arguments from each, as inbiomedical knowledge, but on competition and partialexclusion. Therefore, the structure of biomedicalknowledge is different from that of clinicalknowledge. This difference is used as the basis for adiscussion in which the place of technology,evidence-based medicine and the gap between scientificand clinical knowledge are evaluated. (shrink)

The case of John Snow has long been important to epidemiologists and public health officials. However, despite the fact that there have been many discussions about the various aspects of Snow’s case, there has been virtually no discussion about what guided Snow’s reasoning in his coming to believe his various conclusions about cholera. Here, I want to take up this question in some detail and show that there are a number of specific principles of reasoning that played a crucial role (...) for Snow. Moreover, these principles were episte- mologically important to Snow, a fact about which Snow is explicit in many places. An analysis of Snow’s case suggests that, because of the epistemic role such principles of reasoning can play, health care practitioners ought to understand their practices to be theoretically informed in these ways, and not just data driven.

The existing philosophical views on what is the meaning of causality adequate to medicine are vastly divided. We approach this question and offer two arguments in favor of pluralism regarding concepts of causality. First, we analyze the three main types of research designs (randomized-controlled trials, observational epidemiology and laboratory research). We argue, using examples, that they allow for making causal conclusions that are best understood differently in each case (in agreement with a version of manipulationist, probabilistic and mechanistic definitions, (...) respectively). Second, we analyze clinical practice and argue that these manipulationist, probabilistic and mechanistic causal claims can be used as evidence for different therapeutic decisions. We differentiate among ‘predicting’ that does not change the relata of causal claims, (mechanistic) ‘interferences’, and ‘interventions’ in the strict sense that act on causes to change effects. The central conclusion is that causal claims agreeing with diverse concepts of causality can deliver evidence for different types of therapeutic decisions. (shrink)

Since the beginning of the AIDS epidemic, the proportion of AIDS cases among women has continued to rise. Women constituted 23 percent of the AIDS cases reported to the Centers for Disease Control and Prevention in 1995, and 81 percent of these women were of childbearing age. It was not until 1991, however, that epidemiological studies of women were initiated. By comparison, the representation of HIV-infected women in clinical trials gradually has grown. Undoubtedly, a consequence of the increased numbers (...) of women in clinical and epidemiological research is the earlier identification of and more appropriate treatments for HIV-related syndromes when women present in the clinical setting. Despite this expanded focus on women, however, clear information to guide the treatment of HIV-infected women who are pregnant is still lagging behind. (shrink)

This descriptive study is an attempt to characterize the field known as clinical ethics, with regard to the function of humanities scholars in the clinical setting, e.g., hospitals and ambulatory care clinics. It is not a strict epidemiological study but a qualitative survey, although it reports some empirical data. Most discussions of medical humanities in the literature are conceptual analyses of particular issues, such as informed consent, abortion, confidentiality, etc. Virtually no empirical studies with data on how many (...) clinical ethicists function in what roles and with what educational backgrounds have been reported. This is the first such study of humanities scholars in clinical ethics and will be followed by companion reports of physicians and hospital chaplains who are, by self-report, involved in clinical ethics. This report is an effort to stimulate and encourage dialogue and is in no way definitive. It is a preliminary study, and other needed studies are already underway. (shrink)

This paper analyzes ethnographic and historical data to emphasize the importance of framing health as collective wellbeing. Exploring missionary medical campaigns during the colonial period in East Africa, I connect the institutional legacy of Euro-American Protestant missions on the contemporary frameworks of US global public health provisions at my research site, Mwana Mwema Program. At this network of faith-based, USAID clinics in Kenya that provide treatment for children living with HIV, practitioners care for the wider community within a global health (...) system that bases donor funding on epidemiological criteria. This narrow framing conflicts with practitioners’ notions of healing as collective wellbeing and can exacerbate communal divisions. I argue that Mwana Mwema’s notion of collective wellbeing offers a healthcare framework that faith-based providers can embrace. It yields more holistic care for entire communities and offers an opportunity for those of us in the United States to rethink our notions of health. (shrink)

The term research subject has traditionally been the preferred term in professional guidelines and academic literature to describe a patient or an individual taking part in biomedical research. In recent years, however, there has been a steady shift away from the use of the term 'research subject' in favour of 'research participant' when referring to individuals who take part by providing data to various kinds of biomedical and epidemiological research. This article critically examines this shift, reflecting on the different meanings (...) evoked by the terms 'subject' and 'participant', as well as examining recent examples of patient activism in research. It concludes by suggesting that the wholesale unreflective adoption of the term 'participant' is inappropriate and provides instead a guide on how to determine the circumstances in which the terms subject, participant and activist should legitimately be used.

Violence is a known risk factor for health problems. In this epidemiological study across 5,385 male patients, we investigate the prevalence of perpetrated violence, exposure to violence, their overlap and the relationship between violence, mental, and psychosomatic health, as well as adverse health behaviors, such as self-harming behavior and the consumption of drugs. Participants completed an anonymous questionnaire addressing violence experience, age of victimization/perpetration, frequency, and perceived severity of violence exposure. We considered physical, psychological as well as sexual violence. Information (...) on health status and adverse health behaviors complemented the data. Results showed that 48.4% of the sample reported having experienced violence. The victim-perpetrator overlap formed the largest group, in which the incidence of having experienced multiple types of violence was significantly higher compared to victims and perpetrators. The age-crime curve flattened more slowly with increasing age in this group. Although the perceived severity of exposure to violence is lower in the overlap group, its health status and adverse health behaviors were worse. Interventions should focus on this group since they constitute a burden for the healthcare system. (shrink)

American Academy of Pediatrics (AAP) and American College of Medical Genetics (ACMG) recently provided two recommendations about predictive genetic testing of children. The Clinical Sequencing Exploratory Research Consortium's Pediatrics Working Group compared these recommendations, focusing on operational and ethical issues specific to decision making for children. Content analysis of the statements addresses two issues: (1) how these recommendations characterize and analyze locus of decision making, as well as the risks and benefits of testing, and (2) whether the guidelines conflict (...) or come to different but compatible conclusions because they consider different testing scenarios. These statements differ in ethically significant ways. AAP/ACMG analyzes risks and benefits using best interests of the child and recommends that, absent ameliorative interventions available during childhood, clinicians should generally decline to order testing. Parents authorize focused tests. ACMG analyzes risks and benefits using the interests of the child and other family members and recommends that sequencing results be examined for additional variants that can lead to ameliorative interventions, regardless of age, which laboratories should report to clinicians who should contextualize the results. Parents must accept additional analysis. The ethical arguments in these statements appear to be in tension with each other. (shrink)
