For all the attention in the media about potential side effects of vaccines like Merck's HPV vaccine Gardasil, not enough time or attention has been paid congratulating Merck for its shingles homerun, Zostavax. Zostavax is the only vaccine available to keep shingles from occurring. Studies from 2003 show that it is 50% effective at doing so. The Center for Disease Control recommends that everyone over the age of 60 receive it, and the author agrees with this recommendation since Shingles can be devastating and half of all cases are in people over the age of 60

More than 20% of patients in the Veterans Health Administration (VHA) have diabetes; therefore, disseminating "best practices" in outpatient diabetes care is paramount. The authors' goal was to identify such practices and the factors associated with their development. First, a national VHA diabetes registry with 2008 data identified clinical performance based on the percentage of patients with an A1c >9%. Facilities (n = 140) and community-based outpatient clinics (n = 582) were included and stratified into high, mid, and low performers. Semistructured telephone interviews (31) and site visits (5) were conducted. Low performers cited lack of teamwork between physicians and nurses and inadequate time to prepare. Better performing sites reported supportive clinical teams sharing work, time for non-face-to-face care, and innovative practices to address local needs. A knowledge management model informed our process. Notable differences between performance levels exist. "Best practices" will be disseminated across the VHA as the VHA Patient-Centered Medical Home model is implemented.

BACKGROUND: Improving hospital discharge has become a national priority for teaching hospitals, yet little is known about physician perspectives on factors limiting the quality of discharge care. OBJECTIVES: To describe the discharge process from the perspective of housestaff physicians, and to generate hypotheses about quality-limiting factors and key strategies for improvement. METHODS: Qualitative study with in-depth, in-person interviews with a diverse sample of 29 internal medicine housestaff, in 2010-2011, at 2 separate internal medicine training programs, including 7 different hospitals. We used the constant comparative method of qualitative analysis to explore the experiences and perceptions of factors affecting the quality of discharge care. RESULTS: We identified 5 unifying themes describing factors perceived to limit the quality of discharge care: (1) competing priorities in the discharge process; (2) inadequate coordination within multidisciplinary discharge teams; (3) lack of standardization in discharge procedures; (4) poor patient and family communication; and (5) lack of postdischarge feedback and clinical responsibility. CONCLUSIONS: Quality-limiting factors described by housestaff identified key processes for intervention. Establishment of clear standards for discharge procedures, including interdisciplinary teamwork, patient communication, and postdischarge continuity of care, may improve the quality of discharge care by housestaff at teaching hospitals.

Significant ambiguity exists in the scientific community with regard to the nomenclature of 26-hydroxylated oxysterols. Oxysterols constitute an important class of compounds that have biological roles in the regulation of cholesterol synthesis and as endogenous selective estrogen receptor modulators (SERMs). The ambiguity is attributable to deviations from clearly stated IUPAC rules and is likely to increase as more biologically active oxysterols are identified. This review provides a uniform approach to the naming of 26-hydroxylated sterols for those of current interest and for those on the horizon such as oxysterols of lanosterol that retain the unsaturation at C-24 and C-25 such as (E)-26-hydroxylanosterol. Using this molecule as a starting point, this review hopes to establish a common language to keep all investigators on the same page.

BACKGROUND: Tuberculosis contact investigation identifies individuals who may be recently infected with tuberculosis and are thus at increased risk for disease. Contacts with latent tuberculosis infection (LTBI) are offered chemoprophylaxis to prevent active disease; however, the effectiveness of this intervention is unclear as treatment completion is generally low. METHODS: A retrospective cohort study of 30 561 contacts identified during investigation of 5182 cases of tuberculosis diagnosed in New York City, 1997-2003, was performed. We searched the NYC tuberculosis registry to identify contacts developing active tuberculosis within 4 years of follow-up. We estimated the following: number of contacts undergoing evaluation (ie, tuberculin skin test and/or chest radiograph) per prevalent case diagnosed; number of contacts with LTBI that need to be treated with standard chemoprophylaxis to prevent 1 active case. RESULTS: Of 30 561 contacts, 27 293 (89%) were evaluated and 268 prevalent cases were diagnosed (102 contacts evaluated per prevalent case diagnosed, 95% confidence interval [CI], 90-115). LTBI was diagnosed in 7597 contacts, including 6001 (79%) who initiated chemoprophylaxis, 3642 (61%) who later completed treatment, and 2359 (39%) who did not complete treatment. During 4 years of follow-up, active tuberculosis was diagnosed in 46 contacts with LTBI, including 22 of 6001 (0.4%) who initiated chemoprophylaxis and 24 of 1596 (1.5%) who did not initiate treatment. The absolute risk reduction afforded by chemoprophylaxis initiation was 1.1% (95% CI, .6%-1.9%), leading to an estimated 88 contacts treated to prevent 1 tuberculosis case (95% CI, 53-164). CONCLUSIONS: Contact investigation facilitates active case finding and tuberculosis prevention, even when completion rates of chemoprophylaxis are suboptimal.
