BACKGROUND: Annexin A5 (A5) is a potent anticoagulant protein that shields anionic phospholipids from availability for coagulation reactions. Previous studies showed that antibodies from patients with antiphospholipid (aPL) syndrome (APS) interfere with A5 crystallization and anticoagulant activity. OBJECTIVE: The purpose of this study was to investigate whether reduction of the Annexin A5 Anticoagulant Ratio (A5R) assay (i.e. 'A5 resistance') is associated with adverse clinical events in aPL antibody-positive patients. PATIENTS/METHODS: In an initial discovery phase group of 679 patient samples from a 'real world' tertiary care hospital population who were tested for A5R. This was followed by a validation phase cohort of 71 asymptomatic patients with aPL antibodies and no prior history for an adverse clinical event whose baseline samples were tested for A5R then subsequently observed for up to 4 years. RESULTS: In the discovery phase group, we found a reduction of A5R in aPL antibody-positive patients with thrombosis and/or pregnancy complications compared to aPL antibody-negative patients and controls. In addition, reduced A5R values in both the discovery and validation phase cohorts correlated with the extent of multipositivity for standard APS tests, which has also been shown to be associated with risk for adverse clinical outcomes. CONCLUSION: Reduction of A5R levels was associated with a multipositivity profile in aPL antibody-positive patients within both groups and with the development of adverse clinical events

Reducing health disparities is a national public health priority. Latinos represent the largest racial/ethnic minority group in the United States and suffer disproportionately from poor health outcomes, including cardiovascular disease risk. Academic training programs are an opportunity for reducing health disparities, in part by increasing the diversity of the public health workforce and by incorporating training designed to develop a skill set to address health disparities. This article describes the Training and Career Development Program at the UCLA Center for Population Health and Health Disparities: a multilevel, transdisciplinary training program that uses a community-engaged approach to reduce cardiovascular disease risk in two urban Mexican American communities. Results suggest that this program is effective in enhancing the skill sets of traditionally underrepresented students to become health disparities researchers and practitioners.

BACKGROUND AND OBJECTIVES: Poorly designed labels and dosing tools contribute to dosing errors. We examined the degree to which errors could be reduced with pictographic diagrams, milliliter-only units, and provision of tools more closely matched to prescribed volumes. METHODS: This study involved a randomized controlled experiment in 3 pediatric clinics. English- and Spanish-speaking parents (n = 491) of children 20% deviation), and large error (>2x dose). RESULTS: We found that 83.5% of parents made >/=1 dosing error (overdosing was present in 12.1% of errors) and 29.3% of parents made >/=1 large error (>2x dose). The greatest impact on errors resulted from the provision of tools more closely matched to prescribed dose volumes. For the 2-mL dose, the fewest errors were seen with the 5-mL syringe (5- vs 10-mL syringe: adjusted odds ratio [aOR] = 0.3 [95% confidence interval: 0.2-0.4]; cup versus 10-mL syringe: aOR = 7.5 [5.7-10.0]). For the 7.5-mL dose, the fewest errors were with the 10-mL syringe, which did not necessitate measurement of multiple instrument-fulls (5- vs 10-mL syringe: aOR = 4.0 [3.0-5.4]; cup versus 10-mL syringe: aOR = 2.1 [1.5-2.9]). Milliliter/teaspoon was associated with more errors than milliliter-only (aOR = 1.3 [1.05-1.6]). Parents who received text only (versus text and pictogram) instructions or milliliter/teaspoon (versus milliliter-only) labels and tools made more large errors (aOR = 1.9 [1.1-3.3], aOR = 2.5 [1.4-4.6], respectively). CONCLUSIONS: Provision of dosing tools more closely matched to prescribed dose volumes is an especially promising strategy for reducing pediatric dosing errors.

ISSUES: Mobile phone use has increased dramatically and concurrent with rapid developments in mobile phone-based health interventions. The integration of text messaging interventions promises to optimise the delivery of care for persons with substance dependence with minimal disruption to clinical workflows. We conducted a systematic review to assess the acceptability, feasibility and clinical impact of text messaging interventions for persons with illicit drug and alcohol dependence. APPROACH: Studies were required to evaluate the use of text messaging as an intervention for persons who met Diagnostic and Statistical Manual of Mental Disorders, 4th edition criterion for a diagnosis of illicit drug and/or alcohol dependence. Authors searched for articles published to date in MEDLINE (pubmed.gov), the Cochrane Library, EMBASE, CINAHL, Google Scholar and PsychINFO. KEY FINDINGS: Eleven articles met the search criteria for this review and support the acceptability and feasibility of text messaging interventions for addressing illicit drug and alcohol dependence. Most studies demonstrated improved clinical outcomes, medication adherence and engagement with peer support groups. Text messaging interventions also intervened on multiple therapeutic targets such as appointment attendance, motivation, self-efficacy, relapse prevention and social support. IMPLICATIONS: Suggestions for future research are described, including intervention design features, clinician contact, privacy measures and integration of behaviour change theories. CONCLUSION: Text messaging interventions offer a feasible platform to address a range of substances (i.e. alcohol, methamphetamine, heroin and alcohol), and there is increasing evidence supporting further larger-scale studies.

OBJECTIVE:), a measure of average blood glucose level, is associated with the risk of dementia and cognitive impairment. However, the role of glycemic variability or glucose excursions in this association is unclear. We examined the association of glucose peaks in midlife, as determined by the measurement of 1,5-anhydroglucitol (1,5-AG) level, with the risk of dementia and 20-year cognitive decline. RESEARCH DESIGN AND METHODS:. RESULTS:< 0.001). We found no significant associations in persons without diabetes. CONCLUSIONS:Among participants with diabetes, glucose peaks are a risk factor for cognitive decline and dementia. Targeting glucose peaks, in addition to average glycemia, may be an important avenue for prevention.

The burden of premature death and health loss from ESRD is well described. Less is known regarding the burden of cardiovascular disease attributable to reduced GFR. We estimated the prevalence of reduced GFR categories 3, 4, and 5 (not on RRT) for 188 countries at six time points from 1990 to 2013. Relative risks of cardiovascular outcomes by three categories of reduced GFR were calculated by pooled random effects meta-analysis. Results are presented as deaths for outcomes of cardiovascular disease and ESRD and as disability-adjusted life years for outcomes of cardiovascular disease, GFR categories 3, 4, and 5, and ESRD. In 2013, reduced GFR was associated with 4% of deaths worldwide, or 2.2 million deaths (95% uncertainty interval [95% UI], 2.0 to 2.4 million). More than half of these attributable deaths were cardiovascular deaths (1.2 million; 95% UI, 1.1 to 1.4 million), whereas 0.96 million (95% UI, 0.81 to 1.0 million) were ESRD-related deaths. Compared with metabolic risk factors, reduced GFR ranked below high systolic BP, high body mass index, and high fasting plasma glucose, and similarly with high total cholesterol as a risk factor for disability-adjusted life years in both developed and developing world regions. In conclusion, by 2013, cardiovascular deaths attributed to reduced GFR outnumbered ESRD deaths throughout the world. Studies are needed to evaluate the benefit of early detection of CKD and treatment to decrease these deaths.

Lab-based experimental studies with humans and in animal models demonstrate that the relation between glucocorticoid (GC) levels and performance on measures of higher-order cognitive ability such as executive function (EF) is best described by an inverted U-shape curve. Moderate levels of GCs (cortisol/corticosterone) are associated with comparatively better performance relative to GC levels that are particularly high or low. Although findings from experimental studies are definitive and have high internal validity, the external validity of this association as an aspect of children's development is unknown. Here we analyze data from the Family Life Project (N=1292), a prospective longitudinal sample of children and families in predominantly low-income and rural communities followed longitudinally from infancy through age 60 months. Consistent with the prior experimental literature, we found evidence of an inverted-U relation. For children with relatively low cortisol levels, on average, between the ages 7, 15, 24, and 48 months, those illustrating moderate fluctuations in their cortisol levels over this span tended to show subsequently better EF performance at 60 months, than did children with either highly stable or highly variable temporal profiles. This curvilinear function did not extend to children whose cortisol levels were high, on average. These children tended to show lower EF performance, irrespective the stability of their cortisol levels over time.

We previously defined teaching domains necessary for successful inpatient medicine attending rounds from the trainees' perspective in Role Modeling, Learning Environment, Teaching Process and Team Management. We sought to understand whether trainee characteristics and daily fluctuations in workload influence the prioritization of these domains. We conducted a prospective observational study in general medicine inpatient wards at a university, Veterans Affairs, and a county hospital affiliated with one academic institution over the course of 6 months. All student and resident trainees on internal medicine inpatient wards were eligible to participate. We designed a daily assessment tool on which trainees were asked to identify the teaching domain most important to them, along with information on sex, training level, call-cycle day, patient census, and number of team members absent during rounds. We examined associations between training level and workload factors with the prioritized teaching domain using Pearson's chi-square analysis, adjusted for clustering effects. We collected 1,378 daily assessment cards evaluating 53 (91%) attending physicians. Students valued Teaching Process (𝑃 < 0.001), while senior residents sought Team Management (𝑃 < 0.001). On most days, Teaching Process was prioritized (𝑃 = 0.005). On post-call days and days with a high patient census, Team Management was prioritized (𝑃 < 0.001). Attending physicians may consider tailoring rounds in response to work-related pressures. Days with a high workload are better suited for demonstrating efficient and effective patient care skills.
