Patients’ self management is touted as an important adjunct to medical care for chronic diseases, and some studies have shown that self-management training can improve clinical outcomes. Marta Buszewicz and colleagues performed a randomized controlled trial of 812 UK general practice patients with arthritis, comparing the effectiveness of a six session self management course with receipt of an educational booklet. After 12 months, the trained group had significantly less anxiety and perceived self efficacy, but there were no differences in arthritis pain, physical functioning, or number of GP visits. In a related editorial, Peter Croft and Elaine Hay point out that other self management studies, though admittedly of volunteers, have found more positive results. Despite it being common sense and good patient care to inform patients about their disease, the Buszewicz study calls into question whether self management courses for patients with chronic diseases are worth the time and expense.

Can effective psychotherapy be delivered over the telephone? Karina Lovell et al randomized 70 patients with obsessive compulsive disorder to receive 10 weekly cognitive behavior therapy sessions either in person on by phone. They found that patients receiving the phone sessions had outcomes that were no worse than those with face to face therapy. Such telephone talk therapy might be especially useful in rural or other underserved settings.

Influenza season is upon us, and with it the exhortations of public health authorities to vaccinate everyone but healthy young adults. Tom Jefferson analyzes the evidence for the effectiveness of flu shots and finds it surprisingly thin. Because circulating influenza antigens change every year, research is difficult to do. Systematic reviews of the research contain little convincing evidence of the effectiveness of flu vaccine. Many published studies have methodological problems. Jefferson urges re-evaluation of the worth of national influenza immunization campaigns.

Finally, just before the November 7 elections, South Dakota obstetrician-gynecologist Marvin Buehner describes his personal view of the effects of a recently passed state anti-abortion law that is up for recall. The law, which outlawed all abortions except those performed to avert a woman’s death, has led to a strong grass-roots campaign to repeal it. Buehner provides examples of what he calls the “environment of intimidation” of doctors that anti-abortion groups have created in South Dakota.

This week’s theme issue of the BMJ is devoted to health in the Middle East—as Wasim Maziak puts it in the opening editorial, “No one’s priority, everyone’s problem.” The author vividly evokes a region that has gone from one of the most advanced civilisations in its time, where the foundations of modern medicine were laid, to a region fighting with the legacy of past conflicts and externally imposed boundaries, which includes “some of the poorest and some of he richest countries in the world, whose basic health indicators generally parallel their economic status.” Such vast economic and health discrepancies present equally vast challenges, and the fact that governments have not provided comprehensive health services has led to health care being taken over by market forces. Which, in turn, contributes to ever increasing social differentials.

The fact that spending on defence is hugely higher than spending on health is another problem. So, what is to be done to improve the situation for the more than half a billion people in the region? International action is important—and international interest is reflected in the number of US (and European) co-authors to the issue—but so are community based interventions. Zulfiqar Bhutta and colleagues argue that improving health in the region depends not only on resources but also on political will and social determinants.

These include not least increased freedom and choice—and better sexual and reproductive health services—for women and young people, as Jocelyn DeJong and Golda El-Khoury point out. HIV and AIDS present a particular challenge in the region, whose prevalence is thus far low but may not remain so, as Obermeyer poignantly explains. And Alex Leventhal and colleagues report how successful collaboration in the region contained outbreaks of H5N1 avian flu and may help create an infrastructure for cross border collaboration in emergencies such as outbreaks of infection.

We are always telling our children and young patients to drink their milk so that they will build strong bones, but does calcium supplementation really do that in a meaningful way? Tania Winzenberg and colleagues evaluated 19 studies of calcium supplementation in childhood in a meta-analysis. They found that calcium led to a slight statistical increase in bone mineral density but nothing clinically significant. In an accompanying editorial, Amy Lanou points out that exercise is a proven stimulant to bone density but dietary calcium is not. She recommends a focus on weight-bearing exercise for kids and a revision of child and adolescent calcium intake guidelines.

We can prevent diabetes by getting at-risk patients to lose weight, but that is hard to do and harder to maintain. Giving pills is easy, and Carl Heneghan et al discuss the pros and cons of diabetes prevention with drugs. In the recently published DREAM trial, high-risk patients given rosiglitazone were less than half as likely to develop diabetes as those on placebo, although there were no differences in deaths or other clinical outcomes after three years. Also, the rosiglitazone group had increased rates of congestive heart failure and heart disease. It would be nice to figure out a non-pharmaceutical way to reduce the risk of this common and deadly disease.

Stuart Derbyshire and Adam Burgess looked into the science behind banning mobile phone use in hospitals. In an editorial they report that there is little or no evidence that phones can interfere with medical equipment, especially if the phones are kept three or more feet away. Although beeping and ringing (and conversations) may be annoying, cell phones can be useful in hospitals for both patients and doctors. One study found that hospital doctors were more easily reached by cell phone than by pager. Should these mobile phone bans be removed?

Finally, it turns out that all evidence-based medicine and then there is real evidence-based medicine. That is, all systematic reviews and meta-analyses are not alike. In a study matching Cochrane group drug reviews with reviews of the same drugs supported by industry, Anders Jørgensen and associates found, unsurprisingly, that the industry-supported studies were less critical of the experimental drugs and endorsed them in a more unqualified manner. Cochrane reviews more frequently considered potential biases in the studies and were more cautious in their recommendations.

Anti-thrombotic drugs increase the risk of gastrointestinal bleeding. Jesper Hallas and colleagues performed a case-control study of the risk of GI bleeding in patients taking one or more of these drugs. Their study population was 1443 Danish cases of serious upper GI bleeding and their controls were almost 58,000 age- and sex-matched adults. They found the odds of bleeding increased by about a factor of 2 when taking low-dose aspirin and other antithrombotics except clopidogrel individually. When they were combined, however, the risk increased substantially. The highest risk was for patients combining aspirin and clopidogrel. In an accompanying editorial Joseph Sung advocates using proton pump inhibitors in all patients on combined aspirin and clopidogrel, adding H. pylori prophylaxis in those at increased risk of bleeding.

Stewart Walsh et al discuss the causes of new arrhythmias in patients undergoing non-cardiac surgery. Case series reveal that more than half of these arrhythmias have non-cardiac causes, including especially infection and sepsis. Surgeons and other doctors who take care of postoperative patients should always search diligently for the cause of postoperative arrhythmias, looking at possible surgery-related causes as well as those related to acid-base disturbances and primary cardiac disease.

Everyone seems to be talking about overweight and obesity, but what can doctors do about it? Alison Avenell and associates review the ABCs of obesity management by behavior change. Successful maintenance of weight loss seems to depend on changing both caloric intake and physical activity patterns. The authors give tips on the characteristics of successful diet and exercise programs.  

In what will likely be a controversial commentary, American transplant surgeon Amy Friedman proposes legalizing the payment of patients who donate organs while still alive. She argues that a regulated payment system would increase both donations and donor safety, destroy the black market, and benefit donors, who are the only ones in the current process who don’t get rewarded.
