Randomized Controlled Trial Multicenter Study
German Acupuncture Trials (GERAC) for chronic low back pain: randomized, multicenter, blinded, parallel-group trial with 3 groups.
To our knowledge, verum acupuncture has never been directly compared with sham acupuncture and guideline-based conventional therapy in patients with chronic low back pain. ⋯ Low back pain improved after acupuncture treatment for at least 6 months. Effectiveness of acupuncture, either verum or sham, was almost twice that of conventional therapy.

Comparative Study
Hospitalist care and length of stay in patients requiring complex discharge planning and close clinical monitoring.
Academic medical centers are increasingly employing hospitalists to staff teaching wards. Although studies have demonstrated reduced lengths of stay (LOSs) associated with hospitalist care, it is unclear which patients are most likely to benefit. We sought to determine whether patients with specific diagnoses or discharge needs account for the association between hospitalist care and reduced LOS. ⋯ Teaching hospitalist care was associated with shorter LOS in patients requiring close clinical monitoring and complex discharge planning, without adversely affecting readmission or mortality rates.

Comparative Study
Mechanisms for racial and ethnic disparities in glycemic control in middle-aged and older Americans in the health and retirement study.
Mechanisms for racial/ethnic disparities in glycemic control are poorly understood. ⋯ Latino and African American respondents had worse glycemic control than white respondents. Socioeconomic, clinical, health care, and self-management measures explained approximately a fifth of the HbA(1c) differences. One potentially modifiable factor for which there were racial disparities--medication adherence--was among the most significant independent predictors of glycemic control.

Patients who lose decision-making capacity and lack advance directives and next of kin present a quandary for physicians. Current mechanisms for making treatment decisions for these patients rely on decision makers, such as courts, public guardians, committees, and physicians, who typically do not have sufficient knowledge to predict the patients' preferences. Thus, these mechanisms likely yield decisions that are inconsistent with patients' treatment preferences in many cases. ⋯ A recent analysis suggests that a population-based treatment indicator could predict patient preferences as accurately as patient-appointed surrogates and next of kin. This analysis suggests that a population-based treatment indicator may provide a mechanism to respect the treatment preferences of patients without surrogates and ensure that their treatment preferences are respected as much as the preferences of patients who have surrogates. Collection of data on patients' treatment preferences, especially those without surrogates, incorporation of these data into a treatment indicator, and exploration of ways to implement this approach for patients without surrogates are called for.

The extent to which moderate overweight (body mass index [BMI], 25.0-29.9 [calculated as weight in kilograms divided by height in meters squared]) and obesity (BMI, >/= 30.0) are associated with increased risk of coronary heart disease (CHD) through adverse effects on blood pressure and cholesterol levels is unclear, as is the risk of CHD that remains after these mediating effects are considered. ⋯ Adverse effects of overweight on blood pressure and cholesterol levels could account for about 45% of the increased risk of CHD. Even for moderate overweight, there is a significant increased risk of CHD independent of these traditional risk factors, although confounding (eg, by dietary factors) cannot be completely ruled out.
