Medication use, renin-angiotensin system inhibitors, and acute care utilization after hospitalization in patients with chronic kidney disease.

OBJECTIVES: The aims of this secondary analysis were to: (a) characterize medication use following hospital discharge for patients with chronic kidney disease (CKD), and (b) investigate relationships of medication use with the primary composite outcome of acute care utilization 90 days after hospitalization. METHODS: The CKD-Medication Intervention Trial (CKD-MIT) enrolled acutely ill hospitalized patients with CKD stages 3-5 not dialyzed (CKD 3-5 ND). In this post hoc analysis, data for medication use were characterized, and the relationship of medication use with the primary outcome was evaluated using Cox proportional hazards models. RESULTS: Participants were taking a mean of 12.6 (standard deviation=5.1) medications, including medications from a wide variety of medication classes. Nearly half of study participants were taking angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARB). ACE inhibitor/ARB use was associated with decreased risk of the primary outcome (hazard ratio=0.51; 95% confidence interval 0.28-0.95; CONCLUSIONS: A large number, variety, and complexity of medications were used by hospitalized patients with CKD 3-5 ND. ACE inhibitor or ARB use at hospital discharge was associated with a decreased risk of 90-day acute care utilization

Strategic uses of music in the U.S. history classroom

This study investigated the strategic uses of music in the U.S. history classroom of six expert secondary U.S. history teachers identified by their administrators as expert teachers based on the merit of national certification, exemplary student and/or administration evaluations, high achieving teacher awards, or a combination of these criteria. The settings for this study were rural high schools on block schedules in the north Alabama region. Through observation, interview, and field notes, the study examined the classroom instruction of teachers using music as a strategic instructional teaching tool. Findings indicate that U.S. history teachers using music as a teaching strategy see a significant difference in student attentiveness, engagement in the learning process, and test scores when music is a part of their classroom instruction. Consensus from the history teachers found that music enhances the lesson and is effective in delivering content to the students in such a way that they have a deeper understanding of the history curriculum being taught. Most teachers in this study used music as a 10 to 15 minute exercise within the lesson. However, several teachers used music as a student presentation assignment that encompassed total class time. Data suggests that music is an effective strategy for teaching in the secondary setting because music is an integral part of the human experience, has been a communicator of cultural history throughout the ages, and students living in the present technological age have more access to music that any previous time in history.

Association study of 25 type 2 diabetes related Loci with measures of obesity in Indian sib pairs.

Obesity is an established risk factor for type 2 diabetes (T2D) and they are metabolically related through the mechanism of insulin resistance. In order to explore how common genetic variants associated with T2D correlate with body mass index (BMI), we examined the influence of 25 T2D associated loci on obesity risk. We used 5056 individuals (2528 sib-pairs) recruited in Indian Migration Study and conducted within sib-pair analysis for six obesity phenotypes. We found associations of variants in CXCR4 (rs932206) and HHEX (rs5015480) with higher body mass index (BMI) (β=0.13, p=0.001) and (β=0.09, p=0.002), respectively and weight (β=0.13, p=0.001) and (β=0.09, p=0.001), respectively. CXCR4 variant was also strongly associated with body fat (β=0.10, p=0.0004). In addition, we demonstrated associations of CXCR4 and HHEX with overweight/obesity (OR=1.6, p=0.003) and (OR=1.4, p=0.002), respectively, in 1333 sib-pairs (2666 individuals). We observed marginal evidence of associations between variants at six loci (TCF7L2, NGN3, FOXA2, LOC646279, FLJ39370 and THADA) and waist hip ratio (WHR), BMI and/or overweight which needs to be validated in larger set of samples. All the above findings were independent of daily energy consumption and physical activity level. The risk score estimates based on eight significant loci (including nominal associations) showed associations with WHR and body fat which were independent of BMI. In summary, we establish the role of T2D associated loci in influencing the measures of obesity in Indian population, suggesting common underlying pathophysiology across populations
