Background
Our health care system faces major threats as the number of people with multiple chronic conditions rises dramatically.Objective
To study the use of Online Health Communities (OHCs) as a tool to facilitate high-quality and affordable health care for future generations.Methods
OHCs are Internet-based platforms that unite either a group of patients, a group of professionals, or a mixture of both. Members interact using modern communication technologies such as blogs, chats, forums, and wikis. We illustrate the use of OHCs for ParkinsonNet, a professional network for Parkinson disease whose participants—both patients and professionals—use various types of OHCs to deliver patient-centered care.Results
We discuss several potential applications in clinical practice. First, due to rapid advances in medical knowledge, many health professionals lack sufficient expertise to address the complex health care needs of chronic patients. OHCs can be used to share experiences, exchange knowledge, and increase disease-specific expertise. Second, current health care delivery is fragmented, as many patients acquire relationships with multiple professionals and institutions. OHCs can bridge geographical distances and enable interdisciplinary collaboration across institutions and traditional echelons. Third, chronic patients lack adequate tools to self-manage their disease. OHCs can be used to actively engage and empower patients in their health care process and to tailor care to their individual needs. Personal health communities of individual patients offer unique opportunities to store all medical information in one central place, while allowing transparent communication across all members of each patient’s health care team.Conclusions
OHCs are a powerful tool to address some of the challenges chronic care faces today. OHCs help to facilitate communication among professionals and patients and support coordination of care across traditional echelons, which does not happen spontaneously in busy practice. 相似文献152.

Loss of cables protein expression in human non-small cell lung cancer: a tissue microarray study 总被引:4,自引:0,他引:4

Loss of heterozygosity (LOH) on chromosome 18q is common in lung cancer. The genes involved in LOH on 18q in lung cancer have not been well characterized. Cables, a cyclin-dependent kinase (cdk) interacting protein, has recently been identified and mapped to human chromosome 18q11-12. Cables inhibits cell growth and suppresses tumor formation in nude mice, making it a candidate gene for 18q LOH in lung cancer. Little is known regarding Cables protein expression in human non-small cell lung cancer (NSCLC). In this study we examined Cables expression in 163 NSCLC and nonneoplastic lung specimens using tissue microarrays. Strong nuclear staining was present in normal lung and bronchial tissue. We also evaluated the Cables protein expression pattern and its correlation with histopathologic features and with clinical course of NSCLC. The results of the present study demonstrate for the first time that numerous NSCLCs (45%) lose Cables expression. Furthermore, more adenocarcinomas show a loss of this novel protein than do squamous counterparts. The relationship between tumor histology type and Cables expression appears to be statistically significant (P = 0.028). Our results suggest that Cables may be involved in the pathogenesis of NSCLC. 相似文献

Background
Medical specialty societies are important resources for physicians in advancing their careers. There is a gap in the literature regarding gender disparities within these societies. This study assesses one area where disparities may exist: recognition awards.Objective
To determine whether female physicians are underrepresented among recognition award recipients by the American Academy of Physical Medicine and Rehabilitation (AAPM&R).Design
Surveillance study.Setting and Methods
A published online list of national award recipients from the AAPM&R was analyzed. Forty-eight years of data were included, as the list contained all major recognition award recipients from 1968 to 2015. All awards that were given exclusively to physicians were included. There were eight award categories listed online; seven met this criterion, with a total of 264 individual awards presented. One award category was excluded because it focused on distinguished public service and included both physician and nonphysician (eg, public official) recipients. Awards that were not published online were also excluded.Main Outcome Measures
Total awards given to female versus male physicians from 1968 to 2015, with awards given over the past decade (2006-2015) assessed independently. Lectureships were also analyzed as a set. For awards given to groups of physician recipients, analysis included gender composition of the group (eg, male only versus female only versus mixed-gender physician groups). To assess the proportion of female versus male physiatrists over time, physician gender and specialty data from 3 sources were used: the American Medical Association (AMA), the Association of American Medical Colleges (AAMC), and the AAPM&R.Results
Over the past 48 years, the AAPM&R presented 264 recognition awards to physicians. Award recipients were overwhelmingly male (n = 222; 84.1%). Females received 15.9% (n = 42) of the total awards, although there was an upward trend in female physician recipients to 26.8% (n = 26) from 2006 to 2015. Lectureships were given to 8 female physicians (n = 8 of 77, 10.4%). These results were lower than the proportion of female physicians in the field of physiatry (35% in 2013). Female physicians were more likely to receive awards if they were part of a group and less likely to be recognized if the award was given to only 1 recipient each year or involved a lectureship with a speaking opportunity at a national meeting.Conclusions
To our knowledge, this is the first study in medicine to assess whether female physicians are underrepresented among recipients of recognition awards presented by a national medical society. For nearly half a century, female physicians have been underrepresented in awards presented by the AAPM&R. Although it is encouraging that the proportion of female physicians receiving awards is increasing, further research is needed to understand why underrepresentation remains.Level of Evidence

Fifty-one pediatric patients who were suspected of having central nervous system (CNS) tumors underwent magnetic resonance (MR) imaging using a 0.35 T Diasonics MT/S system. Pulse intervals (TR) ranged from 0.5 to 2.0 seconds with echo delays (TE) of 28 and 56 msec. The ability of MR and contrast-enhanced CT to detect focal lesions, determine lesion extent, and evaluate associated abnormalities was compared. In most patients in whom there was suspected spinal cord disease, comparison with myelography was made. Thirty-three intracranial lesions were detected with at least one imaging modality in 43 cranial examinations. MR was judged superior to CT in 14 of these cases and CT superior to MR in only one. Of eight spinal examinations, there were six that demonstrated abnormal findings. MR was superior to CT in all six cases and better than myelography in four of five cases where myelography was performed. Spin echo (SE) sequences with long pulse intervals were the most sensitive, but in some cases short pulse intervals permitted further characterization of the lesion. Patient motion was not a problem; sedation was routinely used in children younger than five years of age. MR imaging has rapidly become a valuable diagnostic modality in neuroradiology. The lack of ionizing radiation and the ability to evaluate the spinal cord noninvasively makes it particularly attractive in examination of children. 相似文献

Determining optimally designed structures is important for diverse fields of science and engineering. Here we describe a procedure for calculating the optimal design of a switch and apply the method to a bistable microelectromechanical system relay switch. The approach focuses on characterizing the unstable transition state connecting the two stable equilibria to control the force displacements. Small modifications in component shape lead to a substantial improvement in device operation. Fabrication of the optimized devices confirms the predictions. 相似文献

tdic(9;12): a nonrandom chromosome abnormality in childhood B-cell precursor acute lymphoblastic leukemia: a Pediatric Oncology Group Study 总被引:2,自引:0,他引:2

In a review of 432 children with newly diagnosed acute lymphoblastic leukemia (ALL), we identified a new nonrandom translocation, tdic(9;12)(p1?1;p1?2), in the leukemic marrow cells of eight patients. Seven had hypodiploid karyotypes that lacked chromosomes 9 and 12 and contained a der(12), tdic(9;12); the eighth had a pseudodiploid karyotype with two normal 9 chromosomes, one normal 12 and the der(12), tdic(9;12). Abnormalities involving chromosomes other than 9 and 12 were noted in four of the eight patients. All cells with the tdic(9;12) expressed both the common ALL antigen and HLA-DR. Cytoplasmic immunoglobulin, a marker of pre-B ALL, was detected in one case with the tdic(9;12) but was absent in the other seven. Our results suggest that the tdic(9;12)(p1?1;p1?2) rearrangement is specifically associated with leukemic B cell precursors. 相似文献
