) (>0.96), and positive predictive value (PPV) (>0.97). In contrast, the PPVs for type 2 diabetes were 0.642 and 0.778 for the rule-based algorithm and the multinomial regression, respectively. Combination of the rule-based method with chart reviews (

= 695, 7.9%) of persons predicted to have non-type 1 diabetes resulted in perfect PPV for the cases reviewed while increasing overall accuracy (0.983). The

An ICD-10 algorithm combined with targeted chart reviews accurately identified diabetes status/type and could be an attractive option for diabetes surveillance in youth.

To prospectively examine intakes of folate, vitamin B

, and vitamin B

in relation to diabetes incidence in a large U.S. cohort.

A total of 4,704 American adults aged 18-30 years and without diabetes were enrolled in 1985-1986 and monitored until 2015-2016 in the Coronary Artery Risk Development in Young Adults (CARDIA) study. Dietary assessment was conducted by a validated dietary history questionnaire at baseline, in 1992-1993, and in 2005-2006. The cumulative average intakes of folate, vitamin B

, and vitamin B

were used in the analyses. Incident diabetes was ascertained by plasma glucose levels, oral glucose tolerance tests, hemoglobin A

concentrations, and/or antidiabetic medications.

During 30 years (mean 20.5 ± 8.9) of follow-up, 655 incident cases of diabetes occurred. Intake of folate, but not vitamin B

or vitamin B

, was inversely associated with diabetes incidence after adjustment for potential confounders. Compared with the lowest quintile of total folate intake, the multivariable-adjusted hazard ratios (95% CI) in quintiles 2-5 were 0.85 (0.67-1.08), 0.78 (0.60-1.02), 0.82 (0.62-1.09), and 0.70 (0.51-0.97;

= 0.02). Higher folate intake was also associated with lower plasma homocysteine (

< 0.01) and insulin (

< 0.01). Among supplement users, folate intake was inversely associated with serum C-reactive protein levels (

< 0.01).

Intake of folate in young adulthood was inversely associated with diabetes incidence in midlife among Americans. The observed association may be partially explained by mechanisms related to homocysteine level, insulin sensitivity, and systemic inflammation.

We examined changes in glucose-lowering medication spending and quantified the magnitude of factors that are contributing to these changes.

Using the Medical Expenditure Panel Survey, we estimated the change in spending on glucose-lowering medications during 2005-2007 and 2015-2017 among adults aged ≥18 years with diabetes. We decomposed the increase in total spending by medication groups for insulin, by human and analog; and for noninsulin, by metformin, older, newer, and combination medications. For each group, we quantified the contributions by the number of users and cost-per-user. Costs were in 2017 U.S. dollars.

National spending on glucose-lowering medications increased by $40.6 billion (240%), of which insulin and noninsulin medications contributed $28.6 billion (169%) and $12.0 billion (71%), respectively. For insulin, the increase was mainly associated with higher expenditures from analogs (156%). Selleckchem VcMMAE For noninsulin, the increase was a net effect of higher cost for newer medications (+88%) and decreased cost for older medications (-34%). Most of the increase in insulin spending came from the increase in cost-per-user. However, the increase in the number of users contributed more than cost-per-user in the rise of most noninsulin groups.

The increase in national spending on glucose-lowering medications during the past decade was mostly associated with the increased costs for insulin, analogs in particular, and newer noninsulin medicines, and cost-per-user had a larger effect than the number of users. Understanding the factors contributing to the increase helps identify ways to curb the growth in costs.

Uptake of oral pre-exposure prophylaxis (PrEP) remains low. The objective of this analysis was to estimate the potential market size in priority sub-Saharan African countries for a 28-day dual prevention pill (DPP) regimen containing the active pharmaceutical ingredients in oral PrEP and oral contraceptive pills (OCPs) for the prevention of HIV and unintended pregnancy.

We selected 15 countries in sub-Saharan Africa for analysis. Population estimates were based on United Nations Population Division data from 2017. Low, medium and high rates (range 0.25% to 25%) of estimated conversion from current contraceptive method to the DPP were applied by country based on HIV prevalence (≥10% vs <10%), current contraceptive method (OCP, condom or unmet need for contraception) and age group (15-24 or 25-49 years).

In these 15 countries, between 250 000 and 1.25 million women could switch from their current contraceptive method to the DPP. Given that current PrEP use in the 15 countries combined is estimated to be 113 250 (women and men), the most conservative market size estimate would more than double the number of women currently using PrEP.

By leveraging the existing market for OCPs and assuming modest conversion from condom users and women with an unmet need for contraception, the DPP could lead to a 2- to 10-fold increase in PrEP usage in these 15 sub-Saharan African countries, expanding the broader public health benefit of this proven HIV prevention strategy.
