Tenofovir diphosphate (TFV-DP) concentrations measured with dried blood spots (DBS) can be used to classify adherence to emtricitabine/tenofovir disoproxil fumarate (F/TDF) for HIV pre-exposure prophylaxis (PrEP). A TFV-DP of 700 fmol/punch was previously associated with high PrEP efficacy, and was estimated to represent ≥4 doses/week on average. However, interindividual variability in TFV-DP concentrations may lead to adherence misclassification and decrease the precision of adherence-efficacy relationships. The purpose of this analysis was to evaluate sources of TFV-DP variability to improve the precision of TFV-DP for adherence assessments by incorporating individual characteristics. Data and samples from a 36-week study of TFV-DP in DBS, collected biweekly, among 48 HIV-negative volunteers (25 Females/26 Caucasian/10 African American/14 Hispanic) receiving F/TDF at 33%, 67%, and 100% of daily dosing under directly observed therapy were used for analysis. The simplest pharmacokinetic model to describe TFV-DP accumulation with acceptable performance was a one-compartment constant input model. Covariates, including laboratory values and demographics were ranked in importance of their association with post hoc pharmacokinetic (PK) parameters using random forest analyses. Weight and platelet count were included in the final model and simulations were conducted to generate benchmarks for 110 kg) doses/week, amounting to a much lower rate of misspecification (17% vs. 30%) with this individualized model versus previous interpretations. Incorporating body weight and platelet count improved the precision of TFV-DP concentrations for adherence assessments. Previous benchmarks were conservative, indicating that the pharmacological forgiveness of F/TDF may be higher than currently recognized and supports continued investigation of intermittent PrEP dosing regimens.

Plant proteins are gaining attention as sustainable means of meeting the global protein need due to their lower carbon footprint. Nonetheless, the food industry has neglected or underutilized many plant proteins, including buckwheat protein. Buckwheat is a pseudocereal and its groats contain beneficial components such as proteins, dietary fiber, vitamins, and bioactive polyphenols. The protein quality of buckwheat seeds varies between the tartary and common buckwheat types; both are gluten-free and contain considerable amount of indispensable amino acids. This review provides a detailed discussion on the profile, amino acid composition, digestibility, allergenicity, functional properties, and bioactivity of buckwheat proteins. find more Prospects of processing buckwheat for improving protein digestibility and deactivating allergenic epitopes were also discussed. Based on the literature, buckwheat protein has a tremendous potential for utilization in structuring food products and developing peptide-based functional foods for disease prevention. Future research should develop new processing technologies for further improvement of the quality and functional properties of buckwheat protein in order to facilitate its utilization as an alternative plant-based protein toward meeting the global protein supply.
High intake of marine n-3 polyunsaturated fatty acids (PUFA) has been associated with reduced risk of cardiovascular events; however, this has not been confirmed in patients with a recent acute myocardial infarction (AMI). Elderly patients are at particularly increased cardiovascular risk after myocardial infarction, but few trials address this group specifically. Omega-3 fatty acids hold the potential to reduce cardiovascular events with limited adverse effects in this vulnerable group. The hypothesis was that daily addition of 1.8g n-3 PUFA to standard of care secondary prophylaxis in elderly patients who have survived an AMI would reduce the risk of subsequent cardiovascular events during 2 years follow-up.

The OMEMI trial (Omega-3 Fatty acids in Elderly with Myocardial Infarction) is an investigator-initiated, multicenter, randomized clinical trial adding 1.8 g n-3 PUFA (930 mg eicosapentaenoic acid and 660 mg docosohexaenoic acid) versus placebo (corn oil) daily to standard of care in patients aged 70.7%) and 56 (11.0%) in the n-3 PUFA and placebo groups, respectively (
=0.87). Similar results were found in per-protocol analysis (n=893).

We could not detect reduction in clinical events in our elderly patients with recent AMI who were treated with 1.8 g n-3 PUFAs daily for 2 years. Registration URL https//www.clinicaltrials.gov; Unique identifier NCT01841944.

Myocardial infarction with nonobstructive coronary arteries (MINOCA) occurs in 6% to 15% of myocardial infarctions (MIs) and disproportionately affects women. Scientific statements recommend multimodality imaging in MINOCA to define the underlying cause. We performed coronary optical coherence tomography (OCT) and cardiac magnetic resonance (CMR) imaging to assess mechanisms of MINOCA.

In this prospective, multicenter, international, observational study, we enrolled women with a clinical diagnosis of myocardial infarction. If invasive coronary angiography revealed <50% stenosis in all major arteries, multivessel OCT was performed, followed by CMR (cine imaging, late gadolinium enhancement, and T2-weighted imaging and T1 mapping). Angiography, OCT, and CMR were evaluated at blinded, independent core laboratories. Culprit lesions identified by OCT were classified as definite or possible. The CMR core laboratory identified ischemia-related and nonischemic myocardial injury. Imaging results were combined td no mechanism was identified in 15.5% (18/116).

Multimodality imaging with coronary OCT and CMR identified potential mechanisms in 84.5% of women with a diagnosis of MINOCA, 75.5% of which were ischemic and 24.5% of which were nonischemic, alternate diagnoses to myocardial infarction. Identification of the cause of MINOCA is feasible and has the potential to guide medical therapy for secondary prevention.
