From the Office of the National Coordinator: the strategy for advancing the exchange of health information

Electronic health information exchange addresses a critical need in the US health care system to have information follow patients to support patient care. Today little information is shared electronically, leaving doctors without the information they need to provide the best care. With payment reforms providing a strong business driver, the demand for health information exchange is poised to grow. The Office of the National Coordinator for Health Information Technology, Department of Health and Human Services, has led the process of establishing the essential building blocks that will support health information exchange. Over the coming year, this office will develop additional policies and standards that will make information exchange easier and cheaper and facilitate its use on a broader scale.     

The Effect of Dietary Carbohydrate and Fat Manipulation on the Metabolome and Markers of Glucose and Insulin Metabolism: A Randomised Parallel Trial

High carbohydrate, lower fat (HCLF) diets are recommended to reduce cardiometabolic disease (CMD) but low carbohydrate high fat (LCHF) diets can be just as effective. The effect of LCHF on novel insulin resistance biomarkers and the metabolome has not been fully explored. The aim of this study was to investigate the impact of an ad libitum 8-week LCHF diet compared with a HCLF diet on CMD markers, the metabolome, and insulin resistance markers. n = 16 adults were randomly assigned to either LCHF (n = 8, <50 g CHO p/day) or HCLF diet (n = 8) for 8 weeks. At weeks 0, 4 and 8, participants provided fasted blood samples, measures of body composition, blood pressure and dietary intake. Samples were analysed for markers of cardiometabolic disease and underwent non-targeted metabolomic profiling. Both a LCHF and HCLF diet significantly (p < 0.01) improved fasting insulin, HOMA IR, rQUICKI and leptin/adiponectin ratio (p < 0.05) levels. Metabolomic profiling detected 3489 metabolites with 78 metabolites being differentially regulated, for example, an upregulation in lipid metabolites following the LCHF diet may indicate an increase in lipid transport and oxidation, improving insulin sensitivity. In conclusion, both diets may reduce type 2 diabetes risk albeit, a LCHF diet may enhance insulin sensitivity by increasing lipid oxidation.     

Heterogeneity in the smoking behavior of African American women

OBJECTIVE: To assess the association between sociodemographic variables and smoking behavior patterns of African American women. METHODS: Six years of data (N=14,903) from the National Health Interview Surveys were analyzed using multiple logistic regression. RESULTS: African American women in the South were more likely to never smoke and to start smoking later than women in the Northeast. Positive smoking outcomes (never smoking, initiating smoking at later ages, and quitting) were associated with higher education, higher income, and being married. CONCLUSIONS: Variations among African American women suggest the need for targeting specific subgroups at greater risks to reduce disparities in smoking and smoking-related diseases.     

Vertical Mammaplasty Marking Using the Key Hole Pattern

Many modifications of the vertical mammaplasty procedure used to shorten the learning curve have been described. The authors advocate marking the breasts for the vertical mammaplasty operation according to the key hole pattern. They have used inverted T techniques on the upper breast and Lejour’s vertical mammaplasty on the lower breast. A total of 14 patients who had breast hypertrophy and ptosis underwent operations with this marking modification. The amount of removed breast ranged from 285 to 875 g per breast. Hematoma, skin necrosis, skin dehiscence, loss of nipple–areola sensitivity, and distortion were not observed in these cases.     

Clinical echinococcosis.

In 221 patients (0.48% of hospital admissions) with hydatid disease (122 female and 99 males), 81% had single and 19% multiple organs involved. Lungs, liver and spleen as single sites of echinococcosis together represented 83.24% of cases and the liver alone represented 95.24% of instances with multiple organ involvement. One hundred seventy-nine single and 74 multiple cysts (ratio of 2.42/1) represented a total of 363 cysts (1.64 cysts/patient). The incidence of intact cysts was 51.52% and 48.48% had ruptured. Ruptures numbered highest in the lungs (73.44%) and greater in multiple (79.66%) than in single cysts (68.12%). In the liver, 27.14% of single and 54.55% of multiple cysts (40.44% of all liver cysts) had ruptured. Cysts varied in size from 0.8 to 35 cm diameter. Single cysts averaged significantly higher (14.16 cm) and multiple ones lower (5.71 cm) as did intact (6.75 cm) versus reptured cysts (4.33 cm). Except for 10 silent and 15 symptomatic cysts treated medically, all the rest were treated surgically by removal of the endocyst or resection of both endo and exocysts including 205 first, 31 second and 5 third procedures (1.75% of all major operations). Complications occurred in 28.57%. Surgical mortality (3.57%) was markedly lower than with conservative treatment (60%) and significantly less than that of the whole group (14.48%).
