Rationale, design and conduct of a comprehensive evaluation of a primary care based intervention to improve the quality of life of osteoarthritis patients. The PraxArt-project: a cluster randomized controlled trial [ISRCTN87252339]

BACKGROUND: Osteoarthritis (OA) has a high prevalence in primary care. Conservative, guideline orientated approaches aiming at improving pain treatment and increasing physical activity, have been proven to be effective in several contexts outside the primary care setting, as for instance the Arthritis Self management Programs (ASMPs). But it remains unclear if these comprehensive evidence based approaches can improve patients' quality of life if they are provided in a primary care setting. METHODS/DESIGN: PraxArt is a cluster randomised controlled trial with GPs as the unit of randomisation. The aim of the study is to evaluate the impact of a comprehensive evidence based medical education of GPs on individual care and patients' quality of life. 75 GPs were randomised either to intervention group I or II or to a control group. Each GP will include 15 patients suffering from osteoarthritis according to the criteria of ACR. In intervention group I GPs will receive medical education and patient education leaflets including a physical exercise program. In intervention group II the same is provided, but in addition a practice nurse will be trained to monitor via monthly telephone calls adherence to GPs prescriptions and advices and ask about increasing pain and possible side effects of medication. In the control group no intervention will be applied at all. Main outcome measurement for patients' QoL is the GERMAN-AIMS2-SF questionnaire. In addition data about patients' satisfaction (using a modified EUROPEP-tool), medication, health care utilization, comorbidity, physical activity and depression (using PHQ-9) will be retrieved. Measurements (pre data collection) will take place in months I-III, starting in June 2005. Post data collection will be performed after 6 months. DISCUSSION: Despite the high prevalence and increasing incidence, comprehensive and evidence based treatment approaches for OA in a primary care setting are neither established nor evaluated in Germany. If the evaluation of the presented approach reveals a clear benefit it is planned to provide this GP-centred interventions on a much larger scale

Towards an Embodied Sociology of War

While sociology has historically not been a good interlocutor of war, this paper argues that the body has always known war, and that it is to the corporeal that we can turn in an attempt to develop a language to better speak of its myriad violences and its socially generative force. It argues that war is a crucible of social change that is prosecuted, lived and reproduced via the occupation and transformation of myriad bodies in numerous ways from exhilaration to mutilation. War and militarism need to be traced and analysed in terms of their fundamental, diverse and often brutal modes of embodied experience and apprehension. This paper thus invites sociology to extend its imaginative horizon to rethink the crucial and enduring social institution of war as a broad array of fundamentally embodied experiences, practices and regimes

Uterine and fetal blood flow indexes and fetal growth assessment after chronic estrogen suppression in the second half of baboon pregnancy

Although estrogen regulates important aspects of maternal cardiovascular physiology, the role of estrogen on uteroplacental and fetal blood flow is incompletely understood. This study tested the hypothesis that chronically suppressing endogenous estrogen production during the second half of baboon pregnancy alters uterine and fetal blood flow dynamics assessed by ultrasonography. Pregnant baboons were untreated or treated daily with the aromatase inhibitor letrozole or letrozole plus estradiol on days 100–160 of gestation (term = 184 days). Blood flow dynamics were determined by Doppler ultrasonography on day 60 and longitudinally between days 110 and 160 of gestation. Letrozole decreased maternal serum estradiol and estrone concentrations by 95% (P < 0.001). Fetal growth biometrical parameters increased (P < 0.001) between days 110 and 160 of gestation and were similar in untreated and letrozole-treated animals. Uterine, umbilical, and fetal middle cerebral artery pulsatility index and resistance index declined (P < 0.01) by 30–50% and uterine artery volume flow increased sixfold (P < 0.001) between days 60 and 160, but values were similar in untreated, letrozole-treated, and letrozole plus estradiol-treated baboons. Thus uterine and fetal artery blood flow indexes, uterine artery volume flow, and fetal growth were maintained at normal levels despite chronic estrogen suppression in the second half of baboon pregnancy. This suggests that elevated levels of endogenous estrogen are not required to maintain low impedance blood flow within the uteroplacental vascular bed during the second half of nonhuman primate pregnancy
