Disease Management and the Medical Home Model

For the past decade, US physicians have failed to embrace disease management (DM) approaches offered by private DM companies and health plans. Until recently, physicians have not offered an alternative, systematic approach to caring for patients with chronic illnesses and conditions.The medical home model has become the centerpiece of reforms proposed by associations that represent family medicine physicians (the American Academy of Family Physicians [AAFP]) and general internal medicine physicians (the American College of Physicians [ACP]). In February 2007, the AAFP and the ACP were joined by the American Academy of Pediatrics and the American Osteopathic Association in issuing joint principles for the patient-centered medical home. While the medical home model is promoted primarily as a comprehensive approach to primary care reform, there is one aspect where the medical home and DM overlap: care coordination.Medicare has been exploring alternative mechanisms to manage and reimburse chronic care and care-coordination activities. In 2003, the US Congress passed legislation to require pilot projects for chronic care improvement programs; the program implementing this legislation is Medicare Health Support (MHS). To date, very little information has been available about the progress of MHS projects. The three early announcements about MHS progress have not been encouraging: the expected financial results are not being achieved.In December 2006, Congress passed legislation authorizing the Medicare Medical Home Demonstration (MMHD) project. MHS and MMHD are directed at similar patient populations: high-cost, frail, elderly patients with multiple co-morbid conditions. The medical home concept being advanced by primary care physicians has the potential to be competitive with DM companies. Health plans that have built their own DM programs are more likely to be supportive of the medical home model. Do physicians have the ability to compete at providing care-coordination services? There are strong arguments suggesting ‘no’ and strong arguments suggesting ‘yes’.While the medical home model is focused on primary care reform, its effect could be competitive to DM companies and others. The medical home model could affect the flow of hundreds of billions of dollars — money that over time might flow either to physicians or to private companies.     

Spontaneous reports of most distressing concerns in patients with inoperable lung cancer: at present,in retrospect and in comparison with EORTC-QLQ-C30+LC13

Patients with lung cancer experience considerable distress. Therefore, accurate methods for assessing distress and quality of life over time may play a key role for managing and evaluating palliative care. Alternatives to commonly used standardized questionnaires are individual measures. This study prospectively and retrospectively explored the concerns that 46 patients with inoperable lung cancer spontaneously reported as causing most distress close to diagnosis and 6 months later. Changes in content individually generated through a structured inductive freelisting were compared with EORTC-QLQ-C30+LC13 ratings. The results showed that patients perceived a wide variety of concerns as most distressing and that their concerns changed over time. Between 56 and 62% of these concerns were assessed by items included in the EORTC-QLQ-C30+LC13 questionnaires. Furthermore, patients’ reports of most distress from fatigue, pain and dyspnea were not always reflected in intensity ratings of comparable EORTC-QLQ-C30+LC13 items. These results indicate that items included in standardized measures are not always adequate to assess patients’ concerns, priorities and changes over time. In addition to standardized questionnaires, individualized measures may be useful in the clinical palliative setting for providing detailed information about the individual’s problems and prioritizations.

N—酰化壳聚糖膜性能的研究

讨论了一系列N-酰化壳聚糖膜的抗张强度、透水性、VB_(12)的透过性、透氧性以及血液相容性。N-已酰化壳聚糖膜具有良好的血液相容性。在制膜过程中,加入分子量为1500的聚乙二醇为致孔剂,则可使N-己酰化壳聚糖膜的渗透性有较大提高。同时保持较好的血液相容性和强度。     

The effects of hyperbaric oxygen therapy on oxidative stress,inflammation, and symptoms in children with autism: an open-label pilot study

Background  

Recently, hyperbaric oxygen therapy (HBOT) has increased in popularity as a treatment for autism. Numerous studies document oxidative stress and inflammation in individuals with autism; both of these conditions have demonstrated improvement with HBOT, along with enhancement of neurological function and cognitive performance. In this study, children with autism were treated with HBOT at atmospheric pressures and oxygen concentrations in current use for this condition. Changes in markers of oxidative stress and inflammation were measured. The children were evaluated to determine clinical effects and safety.     

Effects of a community-based healthy heart program on increasing healthy women's physical activity: a randomized controlled trial guided by Community-based Participatory Research (CBPR)

Background  

Cardiovascular disease remains the leading killer of women in most developed areas of the world. Rates of physical inactivity and poor nutrition, which are two of the most important modifiable risk factors for cardiovascular disease in women, are substantial. This study sought to examine the effectiveness of a community-based lifestyle-modification program on increasing women's physical activity in a randomized trial guided by community-based participatory research (CBPR) methods.     

Income-related health inequality in Belgium: a longitudinal perspective

This paper provides new evidence on the degree of income-related inequality in self-assessed health in Belgium. First of all, we combine the time dimension, which has been shown to be very important in the analysis of inequality, and the use of the recently developed interval regression approach to transform a categorical health variable in a continuous one. Second, we measure how the long-run inequality differs from the short-run inequality. Finally, we decompose this health-related income mobility index as well as the long-run concentration index (CI) itself into its contributors. Using data from the panel survey of Belgian households (1994–2002), we find that health is pro-rich distributed and that its inequality is underestimated by 9.45% when neglecting the dynamics of individuals over time. Income, education, job status and age are the most important contributors in the CI and the difference between the short-run and long-run inequality.      

A Comparison of a Monofocal Acrysoft IOL Using the “Blended Monovision” Formula with the Multifocal Array IOL for Glasses Independence After Cataract Surgery

We compared the Acrysoft monofocal intraocular lens (IOL) in the mini monovision formula (n = 20) with the Array multifocal intraocular lens (n = 20) for glasses independence after cataract surgery. The Acrysoft monofocal IOL group showed similar and even slightly better results than the Array multifocal IOL group. The monofocal Acrysoft IOL using the mini monovision (blended vision) formula is a good alternative for providing post-cataract surgery glasses independence. Drs.

Evaluation of wound contraction and epithelialization after subcutaneous administration of Theranekron® in cows

Ten bulls (age 7 months, weight 302 ± 15 kg) were used in this study. After sterile preparation of skin, a full thickness wound (20 × 20 mm) was created in each bull. The bulls were randomly assigned into two groups: group 1 received 6 ml Theranekron subcutaneously and group 2 penicillin banzatine 10,000 IU/kg IM. These doses were repeated 6 days after initial wounding. At days 0, 3, 6, 10 and 14, digital photographs were taken from the wounds to calculate wound contraction and epithelialization using geometry. Chi-square test was performed for statistical analysis using SPSS 9 for Windows. There was no significant differences in wound contraction between trial groups (P > 0.05) but a statistical difference was seen in epithelialization between groups (P < 0.05). Epithelialization is one of the most important factors in wound healing. According to the results of the present study, Theranekron can significantly stimulate epithelialization in full thickness wounds in cows during the first 14 days of healing.
