There is accumulating evidence demonstrating that early treatment leads to better outcomes in rheumatoid arthritis. In order to be treated early, patients thus need to be identified at the earliest possible stage. This means identifying patients with rheumatoid arthritis at their earliest clinical signs but it could also mean screening for healthy individuals at high risk of developing rheumatoid arthritis. The different tools available to screen for these individuals are reviewed here and their relevance is discussed. 相似文献

Anticoagulant drugs are the foundation of therapy for patients with VTE. While effective therapeutic agents, anticoagulants can also result in hemorrhage and other side effects. Thus, anticoagulant therapy selection should be guided by the risks, benefits and pharmacologic characteristics of each agent for each patient. Safe use of anticoagulants requires not only an in-depth knowledge of their pharmacologic properties but also a comprehensive approach to patient management and education. This paper will summarize the key pharmacologic properties of the anticoagulant agents used in the treatment of patients with VTE. 相似文献

The purpose of this critical appraisal was to assess the available literature on the association of maternal obesity as a risk factor for childhood obesity and to explore the implications for incorporating this evidence into practice. The increasing prevalence of childhood obesity, with its documented adverse health effects, is a critical public health threat in the United States and worldwide. Research studies have documented increased rates of childhood obesity associated with maternal obesity. Healthcare providers are challenged to expand their competencies to recognize the association of maternal obesity and childhood obesity and to address both primary and secondary prevention of childhood obesity. Stopping the cycle of obesity before it becomes the leading cause of preventable disease and death in the United States is a priority for community health nurses. 相似文献

Oxidative stress appears to play an essential role as a secondary messenger in the normal regulation of a variety of physiological processes, such as apoptosis, survival, and proliferative signaling pathways. Oxidative stress also plays important roles in the pathogenesis of many diseases, including aging, degenerative disease, and cancer. Among cancers, lung cancer is the leading cause of cancer in the Western world. Lung cancer is the commonest fatal cancer whose risk is dependent on the number of cigarettes smoked per day as well as the number of years smoking, some components of cigarette smoke inducing oxidative stress by transmitting or generating oxidative stress. It can be subdivided into two broad categories, small cell lung cancer and non-small-cell lung cancer, the latter is the most common type. Distinct measures of primary and secondary prevention have been investigated to reduce the risk of morbidity and mortality caused by lung cancer. Among them, it seems that physical activity and nutrition have some beneficial effects. However, physical activity can have different influences on carcinogenesis, depending on energy supply, strength and frequency of exercise loads as well as the degree of exercise-mediated oxidative stress. Micronutrient supplementation seems to have a positive impact in lung surgery, particularly as an antioxidant, even if the role of micronutrients in lung cancer remains controversial. The purpose of this review is to examine lung cancer in relation to oxidative stress, physical activity, and nutrition. 相似文献

Introduction: Multi‐disease community health campaigns can be effective for population‐wide HIV testing in a research setting (SEARCH: NCT01864603). We sought to evaluate feasibility and uptake of a community‐led health campaign (CLHC) planned and implemented by village leaders and local clinic workers in Uganda. Methods: Over five months in 2014, locally elected village leaders and Ministry of Health (MoH) clinic staff in a rural parish in Uganda planned a census followed by a CLHC, after training by two SEARCH trial consultants and by leaders from a neighbouring parish that had previously participated in a SEARCH health campaign. We defined feasibility as: (1) elected leaders’ participation in training and implementation of pre‐campaign census and mobilization activities; (2) implementation of all campaign activities by MoH‐funded, local clinic staff; and (3) community participation in the campaign, including point‐of‐care screening for HIV, malaria, hypertension and diabetes, and same‐day referral for male circumcision and family planning (FP). Costing of all salaries and supplies was conducted. Results: Elected leaders from all eight villages in the parish participated in CLHC training. They and local clinic staff met monthly to select and plan CLHC services. Village leaders then leveraged existing volunteer health teams to perform a door‐to‐door census, enumerating 5,202 parish residents over 2 weeks. 2,753 (53%) residents participated in the 6‐day CLHC. Of 1,584 adult participants, 1,474 (93%) tested for HIV: 105/1,474 (7.1%) tested HIV positive. 27% (751/2,753) of participants reported fever and underwent malaria rapid diagnostic testing: 5.3% (40/751) tested positive. Among adults screened, 19% (271/1,452) were hypertensive, and 3% (18/637) had a random blood sugar >11.1 mmol/L. Of 805 men and boys (>10 years), 91 (11%) accepted same‐day clinic referral and underwent medical circumcision. Of 900 women offered same‐day long‐term FP referrals, 25 accepted. The CLHC cost, including census, mobilization and testing services, was $23,597 ($8.57/participant). C onclusions: Elected village leaders successfully planned and conducted a 6‐day multi‐disease health campaign with service provision by local clinic staff that reached over half of a rural Ugandan community. These data suggest it is feasible for local leaders and clinics to adopt a multi‐disease health campaign approach to scale‐up HIV testing in rural Africa. 相似文献

Disparities in antidepressant treatment in Medicaid elderly diagnosed with depression 总被引:3,自引:0,他引:3

OBJECTIVES: To determine whether there were racial or ethnic disparities in the use of antidepressants in low-income elderly patients insured by Medicaid. DESIGN: Examination of 1998 Medicaid claims data. SETTING: Centers for Medicare and Medicaid Services Medicaid claims data for five U.S. states. PARTICIPANTS: All Medicaid recipients aged 65 to 84 with a diagnosis of depression. MEASUREMENTS: Treatment versus no treatment; in those treated, treatment with drugs was classified as old- or new-generation antidepressants. RESULTS: In 1998, 7,339 unique individuals aged 65 to 84 had at least one outpatient encounter with depression as the primary diagnosis. Nearly one in four (24.2%) received no antidepressant drug therapy, and 22% received neither psychotherapy nor an antidepressant. African-American individuals were substantially more likely to be untreated (37.1%) than Hispanic (23.6%), white (22.4%), or Asian (13.8%) individuals. In logistic regression models adjusting for sex, state, long-term care status, and age group, African Americans with a primary diagnosis of depression were almost twice as likely as whites not to receive an antidepressant within the study period (odds ratio=1.91, 95% confidence interval=1.62-2.24). Patients in long-term care facilities and those aged 65 to 74 were less likely to receive treatment. CONCLUSION: Substantial numbers of elderly Medicaid enrollees with a primary diagnosis of depression did not receive antidepressants or behavioral therapy. This gap in care disproportionately affected African-American patients. 相似文献
