(Press-News.org) 1. Surveys Show Doctors and Patients at Odds Over Sharing Medical Information
Once reserved for paper charts, doctors' notes are evolving into the electronic medical record. While electronic medical records hold the potential for greater transparency, improved efficiency, and decreased costs, some worry that sharing doctors' notes electronically could lead to greater patient confusion and more work for the physician. Two articles being published in the December 20 issue of Annals of Internal Medicine use survey data to shed light on both sides of the issue.
In the first article, 173 primary care physicians (PCPs) and 37,856 patients completed a survey before joining a voluntary program that provided electronic links to doctor's notes. The purpose of the survey was to ascertain PCP and patient attitudes toward the potential benefits or harms of the program. The researchers found that PCPs and patients had contrasting opinions on electronic records. The PCPs that chose to participate in the program did so because they thought electronic records would improve patient safety and satisfaction, and could lead to patients being better informed and taking better care of themselves. The PCPs who declined to participate did so because they anticipated increased demands on their time during and between visits. Moreover, many feared that open notes could frighten or confuse patients, especially if the PCPs wrote candidly about sensitive health issues. In contrast, patients had ample enthusiasm for and little concern about the consequences of open notes.
In the second study, researchers conducted a web-based survey of 18,471 patient users of My HealtheVet, the electronic personal health record (PHR) of the Veterans Administration (VA), to explore preferences about sharing electronic health information. The researchers found that four out of five veterans surveyed were interested in sharing access to their PHR with someone outside their health system (a spouse or partner, child, other family member, or a non-VA health care provider). The researchers suggest that future research focus on whether shared access to PHR could reduce the burden of long-distance caregiving and improve communication among multiple care providers. The challenge is providing a system that maintains patient security and privacy at the same time.
2. USPSTF Reviews Evidence on Vitamin D and Calcium Supplementation for Fracture Protection and Cancer Prevention
Evidence Review will Inform Draft Recommendation to be Posted for Public Comment at www.uspreventiveservicestaskforce.org
Studies have suggested that vitamin D supplementation may reduce cancer and fracture risks. Researchers reviewed 19 trials and 28 observational studies to determine the benefits and harms of vitamin D with or without calcium supplementation on clinical outcomes of cancer and fractures in adults. The researchers found that combined vitamin D and calcium supplementation reduces fracture risk in older persons, but vitamin D alone was not effective. There is less evidence to support vitamin D supplementation for cancer prevention. Limited data suggest that high dosages of vitamin D can reduce the risk for total cancer, but more research is needed to draw a firm conclusion. Concern remains about the proper dosing of vitamin D, as too much vitamin D can increase the risk for renal and urinary tract stones. These findings will form the basis of an upcoming recommendation statement on vitamin D supplementation from the U.S. Preventive Services Task Force (USPSTF). When finalized, the USPSTF recommendation will be published in Annals of Internal Medicine.
3. Still No Evidence to Support Vitamin D Supplementation for Prevention of Cardiovascular Disease
Vitamin D deficiency has become increasingly common. While the dangers of vitamin D deficiency are well-documented, there is no universal guideline to define vitamin D insufficiency. Risk factors for vitamin D deficiency include low exposure to ultraviolet light, being elderly or female, low socioeconomic status, and lacking dietary sources. Vitamin D deficiency has been linked to hypertension, myocardial infarction, and stroke, as well as other cardiovascular-related diseases, such as diabetes, congestive heart failure, peripheral vascular disease, atherosclerosis, and endothelial dysfunction. Researchers continue to study the benefits of supplementation. They reviewed published research from 1985 through 2011 to evaluate the effect of vitamin D supplementation on cardiovascular outcomes. Few randomized controlled trials have evaluated the effect of vitamin D replacement on cardiovascular outcomes, and the results have been inconclusive or contradictory. The researchers suggest that more randomized, controlled trials be designed to specifically evaluate the role of vitamin D supplementation in reducing cardiovascular disease.

BOSTON – Patients are overwhelmingly interested in exploring the notes doctors write about them after an office visit, but doctors worry about the impact of such transparency on their patients and on their own workflow, a Beth Israel Deaconess Medical Center (BIDMC) study suggests.
In a study published in the Dec. 20 issue of the Annals of Internal Medicine, patient and doctor attitudes were surveyed extensively prior to the launch of the OpenNotes trial in which patients at BIDMC, Geisinger Health System of Danville, PA, and Harborview Medical Center in Seattle were ...
An increase or decrease in your blood pressure during middle age can significantly impact your lifetime risk for cardiovascular disease (CVD), according to research in Circulation: Journal of the American Heart Association.
Researchers found people who maintained or reduced their blood pressure to normal levels by age 55 had the lowest lifetime risk for CVD (between 22 percent to 41 percent risk). In contrast, those who had already developed high blood pressure by age 55 had a higher lifetime risk (between 42 percent to 69 percent risk).
Using data from 61,585 participants ...
What do sweaty palms and abnormal heart rhythms have in common? Both can be initiated by the nervous system during adrenaline-driven "flight or fight" stress reaction when the body senses danger.
Governed by the sympathetic nervous system, an abnormal "flight or fight" stress response which causes excessive sweaty palms (called hyperhidrosis) may also contribute to problems like dangerous irregular heart rhythms from the lower chambers of the heart, called ventricular arrhythmias.
UCLA cardiologists have found that surgery to snip nerves related to the sympathetic ...

High bodily levels of the trace elements nickel and selenium may lower the risk of developing the most common type of pancreatic cancer, finds research published online in Gut.
Similarly, high levels of lead, arsenic, and cadmium could boost the likelihood of developing the disease, the study shows.
The researchers assessed 12 trace element levels in the toenails of 118 patients with exocrine pancreatic cancer—the most common form of the disease—and just under 400 hospital patients without cancer.
Nails, and particularly toenails, are considered reliable indicators ...
Women with endometriosis are up to twice as likely to develop inflammatory bowel disease as those without this reproductive disorder, suggests a large study published online in Gut.
And the effect can last for up to 20 years after their diagnosis of endometriosis—a condition in which cells from the womb lining implant in other areas of the body.
Endometriosis is relatively common, and thought to affect as many as one in 10 women during their child bearing years.
The researchers tracked the long term health of more than 37,000 Danish women who had been admitted to ...
"Mindfulness" exercises, which focus on experiencing the present moment, no matter how difficult, can help curb the stress and fatigue associated with painful rheumatoid joint disease, indicates a small study published online in the Annals of Rheumatic Diseases.
The authors base their findings on 73 patients between the ages of 20 and 70, all of whom had had painful joint disease, caused by rheumatoid arthritis, ankylosing spondylitis, or psoriatic arthritis for at least a year.
Half of them were randomly allocated to scheduled "mindfulness" exercises, which took place ...

As Americans live longer with multiple medical conditions, managing their care is becoming increasingly challenging. Being able to define and measure patient complexity has important implications for how care is organized, how physicians and health care systems are paid, and how resources are allocated. In an article in the Dec. 20 Annals of Internal Medicine, a team of Massachusetts General Hospital (MGH) researchers report finding that primary care physicians define patient complexity using a broader range of factors – including mental health, social factors and financial ...
