People who inject drugs (PWID) are at risk for infective endocarditis (IE). Hospitalization rates related to misuse of prescription opioids and heroin have increased in recent years, but there are no recent investigations into rates of hospitalizations from injection drug use-related IE (IDU-IE). Using the Health Care and Utilization Project National Inpatient Sample (HCUP-NIS) dataset, we found that the proportion of IE hospitalizations from IDU-IE increased from 7% to 12.1% between 2000 and 2013. Over this time period, we detected a significant increase in the percentages of IDU-IE hospitalizations among 15- to 34-year-olds (27.1%–42.0%; P < .001) and among whites (40.2%–68.9%; P < .001). Female gender was less common when examining all the IDU-IE (40.9%), but it was more common in the 15- to 34-year-old age group (53%). Our findings suggest that the demographics of inpatients hospitalized with IDU-IE are shifting to reflect younger PWID who are more likely to be white and female than previously reported. Future studies to investigate risk behaviors associated with IDU-IE and targeted harm reduction strategies are needed to avoid further increases in morbidity and mortality in this rapidly growing population of young PWID.

Background: The health benefits and risks of dietary supplementation use remain controversial. Objective: To evaluate the association between dietary supplement use, levels of nutrient intake from foods and supplements, and mortality among US adults. Design: Prospective cohort study. Setting: National Health and Nutrition Examination Survey (NHANES) 1999–2010 linked to National Death Index Mortality Data. Patients: 30,899 US adults aged 20+ years who answered questions on dietary supplement use. Measurements: Dietary supplement use in the past 30 days and nutrient intake from foods and supplements. Outcomes included mortality from all causes, cardiovascular disease (CVD), and cancer. Results: During a median follow-up of 6.1 years, a total of 3,613 total deaths occurred, including 945 CVD deaths and 805 cancer deaths. Ever use of dietary supplements was not associated with mortality outcomes. Adequate nutrient intake (≥ Estimated Average Requirement or Adequate Intake) of vitamin A, vitamin K, magnesium, and zinc was associated with reduced all-cause or CVD mortality, but the associations were confined to nutrient intake from foods not supplements. Excess nutrient intake (> Tolerable Upper Intake Level) of calcium was associated with an increased risk of cancer mortality (> vs. ≤ Tolerable Upper Intake Level: multivariable-adjusted mortality rate ratio = 1.62, 95% CI: 1.07, 2.45; multivariable-adjusted mortality rate difference = 1.7, 95% CI: −0.1, 3.5 per 1,000 person-years), and the association appeared to be related to calcium intake from supplements (≥1000 mg/d vs. non-users: multivariable-adjusted mortality rate ratio=1.53, 95% CI: 1.04, 2.25; multivariable-adjusted mortality rate difference = 1.5, 95% CI: −0.1, 3.1 per 1,000 person-years) not foods. Limitations: Results from observational data may be affected by residual confounding. Reporting of dietary supplement use is subject to recall bias. Conclusion: Use of dietary supplements is not associated with mortality benefits among US adults. Primary Funding Source: National Institutes of Health

BackgroundAlthough more individuals are sharing their experiences with chronic pain or illness through blogging (writing an Internet web log), research on the psychosocial effects and motivating factors for initiating and maintaining a blog is lacking.ObjectiveThe objective was to examine via online questionnaire the perceived psychosocial and health benefits of blogging among patients who use this media to communicate their experience of chronic pain or illness.MethodsA 34-item online questionnaire was created, tested, and promoted through online health/disease forums. The survey employed convenience sampling and was open from May 5 to July 2, 2011. Respondents provided information regarding demographics, health condition, initiation and upkeep of blogs, and dynamics of online communication. Qualitative data regarding respondents’ blogging experiences, expectations for blogging, and the perceived effects from blogging on the blogger’s health, interpersonal relationships, and quality of life were collected in the form of written narrative.ResultsOut of 372 respondents who started the survey, 230 completed the entire questionnaire. Demographic data showed survey respondents to be predominantly female (81.8%) and highly educated (97.2% > high school education and 39.6% with graduate school or professional degrees). A wide spectrum of chronic pain and illness diagnoses and comorbidities were represented. Respondents reported that initiating and maintaining an illness blog resulted in increased connection with others, decreased isolation, and provided an opportunity to tell their illness story. Blogging promoted accountability (to self and others) and created opportunities for making meaning and gaining insights from the experience of illness, which nurtured a sense of purpose and furthered their understanding of their illness.ConclusionsResults suggest that blogging about chronic pain and illness may decrease a sense of isolation through the establishment of online connections with others and increases a sense of purpose to help others in similar situations. Further study involving a larger sample size, a wider range of education levels, and respondents with different types and magnitudes of illnesses will be needed to better elucidate the mechanism of the observed associations in this understudied area.

BackgroundIncreasing physical activity (PA) during the school day and out-of-school time are critical strategies for preventing childhood obesity and improving overall health. The purpose of the present investigation was to examine schoolchildren’s volume and type of PA during school-time and out-of-school, compared to national recommendations and differences by sex and weight status.MethodsThis cross-sectional analysis included 517 3rd-5th grade schoolchildren from 13 New England elementary schools (October 2013-January 2014). Demographics were collected by parent questionnaire. Measured height and weight were used to categorize child weight status. Accelerometer data were collected over 7 days. PA was coded as total activity counts and minutes of sedentary, light, and moderate-to-vigorous physical activity (SED, LPA, MVPA) during 1) school, 2) weekday out-of-school, 3) weekend, and 4) total daily time. Multivariable mixed models were used to examine associations between sex and weight status and total counts, SED, LPA, and MVPA, controlling for demographics, wear-time, and clustering within schools.Results453 participants (60.5 % girls; mean age 9.1 years; 30.5 % overweight/obese) had valid accelerometer wear time (≥3 days, ≥ 10 h/day). Few children achieved 60 min total daily (15.0 %) or school-time (8.0 %) MVPA recommendations. For all time-of-day categories, girls achieved fewer MVPA minutes than boys (p < .0001), and overweight/obese participants achieved fewer MVPA minutes than normal/underweight participants (p = 0.05). Minutes of LPA declined by grade-level (p < .05) and were lower in girls than boys during school-time only (p < .05).ConclusionDisparities in MVPA by sex and weight status across school and out-of-school time highlight the need for programs with equitable reach.

Objective To determine the relationship between serum vitamin D levels and cardiometabolic risk factors independent of adiposity in urban schoolchildren. Study design We assessed the relationships among serum 25-hydroxyvitamin D [25(OH)D], adiposity measured by body mass index (BMI) z-score (BMIz), and 6 cardiometabolic risk factors (total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, interleukin-6, and C-reactive protein [CRP]) in a cross-sectional sample of 263 racially and ethnically diverse schoolchildren from the Boston area during late winter. Multivariate regression analyses adjusting for sociodemographic characteristics and BMIz examined associations of 25(OH)D and cardiometabolic risk factors. Results Overall, 74.6% of the children were vitamin D deficient [25(OH)D <50 nmol/L; mean, 41.8 ± 13.7 nmol/L]; 45% were overweight or obese (20%and 25%, respectively; BMIz = 0.75 ± 1.1). The 25(OH)D level was not associated with BMIz, but was positively associated with the cardiometabolic risk factor CRP (β = 0.03; P < .05). BMIz was associated with elevated triglycerides (β = 0.13), CRP (β = 0.58), and interleukin-6 (β= 0.14) and low high-density lipoprotein cholesterol (β = −0.09; all P < .01). Conclusions Vitamin D deficiency is highly prevalent during the late winter months in urban schoolchildren living in the northeastern United States. This widespread deficiency may contribute to the lack of associations between 25(OH)D and both BMIz and cardiometabolic risk factors. The association between 25(OH)D and CRP warrants further study.

Discrepancies exist among food processing classification systems and in the relationship between processed food intake and dietary quality of children. This study compared inter-rater reliability, food processing category, and the relationship between processing category and nutrient concentration among three systems (Nova, International Food Information Council (IFIC), and University of North Carolina at Chapel Hill (UNC)). Processing categories for the top 100 most commonly consumed foods children consume (NHANES 2013–2014) were independently coded and compared using Spearman’s rank correlation coefficient. Relative ability of nutrient concentration to predict processing category was investigated using linear discriminant analysis and multinomial logistic regression and compared between systems using Cohen’s kappa coefficient. UNC had the highest inter-rater reliability (ρ = 0.97), followed by IFIC (ρ = 0.78) and Nova (ρ = 0.76). UNC and Nova had the highest agreement (80%). Lower potassium was predictive of IFIC’s classification of foods as moderately compared to minimally processed (p = 0.01); lower vitamin D was predictive of UNC’s classification of foods as highly compared to minimally processed (p = 0.04). Sodium and added sugars were predictive of all systems’ classification of highly compared to minimally processed foods (p < 0.05). Current classification systems may not sufficiently identify foods with high nutrient quality commonly consumed by children in the U.S.
