Young Adults at Risk for Excess Alcohol Consumption Are Often Not Asked or Counseled About Drinking Alcohol

Background  

Excessive alcohol consumption is most widespread among young adults. Practice guidelines recommend screening and physician advice, which could help address this common cause of injury and premature death.     

Organizational Dimensions of Relationship-centered Care

Four domains of relationship have been highlighted as the cornerstones of relationship-centered health care. Of these, clinician-patient relationships have been most thoroughly studied, with a rich empirical literature illuminating significant linkages between clinician-patient relationship quality and a wide range of outcomes. This paper explores the realm of clinician-colleague relationships, which we define to include the full array of relationships among clinicians, staff, and administrators in health care organizations. Building on a stream of relevant theories and empirical literature that have emerged over the past decade, we synthesize available evidence on the role of organizational culture and relationships in shaping outcomes, and posit a model of relationship-centered organizations. We conclude that turning attention to relationship-centered theory and practice in health care holds promise for advancing care to a new level, with breakthroughs in quality of care, quality of life for those who provide it, and organizational performance.     

Instant Vertebral Assessment: A Noninvasive Dual X-ray Absorptiometry Technique to Avoid Misclassification and Clinical Mismanagement of Osteoporosis

The presence of a vertebral fracture significantly increases the risk of future fracture, classifies a patient with "clinical" osteoporosis, and usually results in treatment for osteoporosis. However, the majority of vertebral fractures are silent, and lateral X-rays (the standard method for identification) are not routinely obtained. Instant vertebral assessment (IVA), a technology that utilizes dual X-ray absorptiometry (DXA), provides rapid assessment of vertebral fractures and is highly correlated with vertebral fractures, as assessed on standard lateral spine X-rays. To assess the role of IVA in patient management, we examined standard bone mineral density (BMD) of the spine, total hip, and femoral neck and spine IVA by DXA in 482 participants screened for an osteoporosis study, who had no previous knowledge of vertebral fractures. Using World Health Organization (WHO) guidelines, subjects were classified using BMD at the spine, total hip, femoral neck, or any combination of these central sites. In addition, we considered subjects as osteoporotic if they had vertebral fractures independent of low bone density. We found that vertebral fractures assessed by IVA were present in 18.3% of asymptomatic postmenopausal women recruited for this study. The sensitivity of BMD alone to diagnose osteoporosis based on either a vertebral fracture or low BMD using WHO criteria ranged from 40 to 74%. This means that between 26 and 60% of osteoporotic individuals could have potentially been missed. Furthermore, 11.0-18.7% of clinically osteoporotic individuals would have been classified as normal by BMD criteria alone. We conclude that IVA is a useful adjunct in the clinical identification of osteoporosis and may prevent mismanagement of osteoporotic patients.     

Stability and decline in gross motor function among children and youth with cerebral palsy aged 2 to 21 years

This paper reports the construction of gross motor development curves for children and youth with cerebral palsy (CP) in order to assess whether function is lost during adolescence. We followed children previously enrolled in a prospective longitudinal cohort study for an additional 4 years, as they entered adolescence and young adulthood. The resulting longitudinal dataset comprised 3455 observations of 657 children with CP (369 males, 288 females), assessed up to 10 times, at ages ranging from 16 months to 21 years. Motor function was assessed using the 66-item Gross Motor Function Measure (GMFM-66). Participants were classified using the Gross Motor Function Classification System (GMFCS). We assessed the loss of function in adolescence by contrasting a model of function that assumes no loss with a model that allows for a peak and subsequent decline. We found no evidence of functional decline, on average, for children in GMFCS Levels I and II. However, in Levels III, IV, and V, average GMFM-66 was estimated to peak at ages 7 years 11 months, 6 years 11 months, and 6 years 11 months respectively, before declining by 4.7, 7.8, and 6.4 GMFM-66 points, in Levels III, IV, and V respectively, as these adolescents became young adults. We show that these declines are clinically significant.     

Antioxidant intake and pancreatic cancer risk

BACKGROUND:

Oxidative stress causes damage to many components of human cells (ie, proteins, lipids, and DNA) and is involved in carcinogenesis. Nutrients with antioxidant properties may protect against oxidative stress. In this study, the authors examined the intake of antioxidants from diet and supplements in relation to pancreatic cancer risk among participants of the Vitamins and Lifestyle (VITAL) Study.

METHODS:

The participants included 77,446 men and women ages 50 to 76 years who were residents of western Washington State and who completed a baseline questionnaire between 2000 and 2002. Participants reported usual diet over the past year and use of supplements over the past 10 years in addition to demographic and lifestyle factors. During a median follow‐up of 7.1 years, 184 participants developed pancreatic adenocarcinoma. Cox proportional hazards models were used to estimate multivariable‐adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for 7 antioxidants: β‐carotene, lutein plus zeaxanthin, lycopene, vitamin C, vitamin E, selenium, and zinc.

RESULTS:

An inverse association was observed between dietary selenium and the risk of pancreatic cancer (medium vs low intake: HR, 0.58; 95% CI, 0.35‐0.94; high vs low intake: HR, 0.44; 95% CI, 0.23‐0.85; P_trend = .01); however, when supplemental and dietary exposures were combined, the association was no longer statistically significant.

CONCLUSIONS:

Dietary selenium intake was inversely associated with the risk of pancreatic cancer, and the observed association was attenuated by selenium supplementation. Cancer 2013. © 2012 American Cancer Society.
