Women and men with coronary heart disease in three countries : are they treated differently?

Non-medical determinants of medical decision making were investigated in an international research project in the US, in the UK and in Germany. The key question in this paper is whether and to what extent doctors' diagnostic and therapeutic decisions in coronary heart disease (CHD) are influenced by the patients' gender. A factorial experiment with a videotaped patient consultation was conducted. Professional actors played the role of patients with symptoms of CHD. Several alternative versions were taped featuring the same script with patient-actors of different sex, age, race and socio-economic status. The videotapes were presented to a randomly selected sample of 128 primary care physicians in each country. Using an interview with standardized and open-ended questions, physicians were asked how they would diagnose and treat such a patient after they had seen the video. Results show gender differences in the diagnostic strategies of the doctors. Women were asked different questions, a CHD was mentioned more often as a possible diagnosis for men than for women, and physicians were less certain about their diagnosis with female patients. Moreover, results indicate that gender differences in management decisions (therapy and lifestyle advice) are less pronounced and less consistent than in diagnostic decisions. Magnitude of gender effect on doctors' decisions varies between countries with smaller influences in the US. Although patients with identical symptoms were presented, primary care doctors’ behavior differed by patients' gender in all three countries under study. These gender differences suggest that women may be less likely to receive an accurate diagnosis and appropriate treatment than men

Fluid manipulation among individuals with lower urinary tract symptoms: a mixed methods study

To determine, qualitatively and quantitatively, how individuals use fluid manipulation to self-manage the urinary symptoms of daytime frequency, urgency and urine leakage and the underlying rationale for this behaviour

Med Care

Abstract Background: As physicians are pressured to deliver an increasing number of preventive services, follow guidelines, engage in evidence-based practice, and deliver patient-centered care in managerially driven organizations, they struggle with how much control they have over their time

Intestinal antibody responses to a live oral poliovirus vaccine challenge among adults previously immunized with inactivated polio vaccine in Sweden.

BACKGROUND: Our understanding of the acquisition of intestinal mucosal immunity and the control of poliovirus replication and transmission in later life is still emerging. METHODS: As part of a 2011 randomised, blinded, placebo-controlled clinical trial of the experimental antiviral agent pocapavir (EudraCT 2011-004804-38), Swedish adults, aged 18-50 years, who had previously received four doses of inactivated polio vaccine (IPV) in childhood were challenged with a single dose of monovalent oral polio vaccine type 1 (mOPV1). Using faecal samples collected before and serially, over the course of 45 days, after mOPV1 challenge from a subset of placebo-arm participants who did not receive pocapavir (N=12), we investigated the kinetics of the intestinal antibody response to challenge virus by measuring poliovirus type 1-specific neutralising activity and IgA concentrations. RESULTS: In faecal samples collected prior to mOPV1 challenge, we found no evidence of pre-existing intestinal neutralising antibodies to any of the three poliovirus serotypes. Despite persistent high-titered vaccine virus shedding and rising serum neutralisation responses after mOPV1 challenge, intestinal poliovirus type 1-specific neutralisation remained low with a titer of ≤18.4 across all time points and individuals. Poliovirus types 1-specific, 2-specific and 3-specific IgA remained below the limit of detection for all specimens collected postchallenge. INTERPRETATION: In contrast to recent studies demonstrating brisk intestinal antibody responses to oral polio vaccine challenge in young children previously vaccinated with IPV, this investigation finds that adults previously vaccinated with IPV have only modest intestinal poliovirus type 1-specific neutralisation and no IgA responses that are measurable in stool samples following documented mOPV1 infection

Research strategies for organizational history:a dialogue between historical theory and organization theory

If history matters for organization theory, then we need greater reflexivity regarding the epistemological problem of representing the past; otherwise, history might be seen as merely a repository of ready-made data. To facilitate this reflexivity, we set out three epistemological dualisms derived from historical theory to explain the relationship between history and organization theory: (1) in the dualism of explanation, historians are preoccupied with narrative construction, whereas organization theorists subordinate narrative to analysis; (2) in the dualism of evidence, historians use verifiable documentary sources, whereas organization theorists prefer constructed data; and (3) in the dualism of temporality, historians construct their own periodization, whereas organization theorists treat time as constant for chronology. These three dualisms underpin our explication of four alternative research strategies for organizational history: corporate history, consisting of a holistic, objectivist narrative of a corporate entity; analytically structured history, narrating theoretically conceptualized structures and events; serial history, using replicable techniques to analyze repeatable facts; and ethnographic history, reading documentary sources "against the grain." Ultimately, we argue that our epistemological dualisms will enable organization theorists to justify their theoretical stance in relation to a range of strategies in organizational history, including narratives constructed from documentary sources found in organizational archives.
