23 and 0.02, respectively; annualized relapse rates were 0.07 and 0.08, respectively; and trough natalizumab serum levels and α4-integrin saturation were comparable. Natalizumab 300 mg subcutaneous Q4W was comparable to 300 mg intravenous Q4W dosing with respect to efficacy, pharmacokinetics/pharmacodynamics, and safety. Natalizumab 300 mg subcutaneous Q4W was comparable to 300 mg intravenous Q4W dosing with respect to efficacy, pharmacokinetics/pharmacodynamics, and safety. In this study, the aim was to evaluate the prevalence of vitamin D, vitamin B12, ferritin, and folate deficiencies in adolescence to clarify the need for early diagnosis and therapy. The medical records of adolescents between 10 and 18 years of age between 01 September 2018 and 28 February 2019 as healthy with non-specific complaints, or due to well-child care visits, were analyzed retrospectively. A total of 1847/2507 (73.6%) adolescents were included in the study. The prevalence of vitamin D deficiency was 25.7% (n 178/691). Vitamin B12 deficiency prevalence was 69.2% (n 753/1088). The prevalence of anemia and ferritin deficiency was 4.8% and 13.26%. The prevalence of folate deficiency was 37.9% (n 413/1088). VDD prevalence was statistically significantly higher in females than males (F/M116/62). VB12D prevalence, the number and mean age of females with hemoglobin deficiency, and low ferritin levels was found to be statistically significantly higher in females than males. The prevalence of vitamin D, vitamin B12, folate deficiency and low ferritin levels was found to be high among adolescents. In particular, adolescents admitting with non-specific complaints and for control purposes in big cities must be considered to be at risk for the deficiency of these vitamins and low level of ferritin.

It is important that the assigned clinical stage matches expectations, and generally corresponds with how a health care professional would intuitively stage the patient. We therefore investigated the relationship between King's clinical ALS stage and ALS stage as intuitively assigned by health care professionals. Methods We wrote 17 case vignettes describing people with ALS at different disease stages from very early limited disease involvement through to severe, multi-domain disease. During two workshops, we asked health care professionals to intuitively stage the vignettes and compared the answers with the actual King's clinical ALS stage. Results There was a good correlation between King's clinical ALS stage and intuitively assigned stage, with a Spearman's Rank correlation coefficient of 0.64 (p  less then  0.001). There was no difference in the intuitive stages assigned by practitioners of different types or at different levels of experience. Conclusions Across a spectrum of ALS scenarios, King's clinical ALS stage corresponds to intuitive ALS stage as assigned by a range of health care professionals. The prevalence of electronic-cigarette (e-cigarette) product placement in music videos is on the rise and currently unregulated. This promotional activity is concerning given the popularity of music videos among young adults. We examined associations between self-reported levels of exposure to music videos with any e-cigarette product placement or imagery and susceptibility to use e-cigarettes and e-cigarette use. A representative sample of young adults (18-24 years of age), residing in California ( = 1,280), completed online surveys assessing self-reported exposure to music videos with e-cigarette product placement or imagery and susceptibility to use e-cigarettes and e-cigarette use. Adjusted and weighted regression analyses were used for statistical analyses. Participants exposed to any e-cigarette product placement or imagery in music videos were more likely to report lifetime e-cigarette use (relative risk ratio [ ] 2.81) and past 30-day use ( 3.64) compared with participants with no exposure. Additionally, participants with greater levels of exposure were more likely to report lifetime e-cigarette use ( 1.13) and past 30-day use ( 1.20) compared with participants with lower levels of exposure. Among those with any exposure, participants younger than 21 years of age (i.e., under the tobacco purchasing age in the United States) were more likely to report lifetime e-cigarette use ( 4.68) compared with those aged 21 years and older. Restricting e-cigarette product placement or imagery in music videos may minimize marketing exposure and risk for vaping among young adults, especially among those under the tobacco purchasing age.

We aimed to investigate associations between NT-proBNP levels and development of global and regional myocardial impairment, dyssynchrony, and risk of developing myocardial scar over time. Methods and Results We included 2416 adults (45-84 years) without baseline clinical cardiovascular disease from MESA (Multi-Ethnic Study of Atherosclerosis). NT-proBNP was assessed at baseline (2000-2002). Cardiac magnetic resonance-measured left ventricular parameters were assessed at baseline and year 10 (2010-2012). Tagged cardiac magnetic resonance and myocardial dyssynchrony were assessed. We used linear and logistic regression models to study the relationships between quartiles of NT-proBNP levels and outcome variables. Left ventricular parameters decreased over time. After 10-year follow-up and adjusting for cardiovascular disease risk factors, people in the highest quartile had significantly greater decline in left ventricular ejection fraction (-1.
