The What’s, Where’s, and Why’s of What Your Family Eats: The Burlington Children’s Space Farm To Table Program

Introduction: Preventing childhood obesity is a national priority, and changing dietary behavior in both children and adults is challenging. Burlington Children’s Space, Inc. (BCS), a private, non-profit early education and childcare center providing services for families in the Burlington area, is trying to do just that. The Farm to Table Project was designed to positively influence the food choices of students and their families as well as to cultivate a relationship between families and local farmers. In an effort to secure expanded funding for the school’s food program, BCS requested that we assess the effectiveness of their Food Programhttps://scholarworks.uvm.edu/comphp_gallery/1032/thumbnail.jp

A retrospective analysis of clinical use of alirocumab in lipoprotein apheresis patients

BACKGROUND: The previously published ODYSSEY ESCAPE trial demonstrated a significant reduction in the use of lipoprotein apheresis for heterozygous familial hypercholesterolemia (HeFH) patients when placed on alirocumab 150 mg every 2 weeks. In patients with HeFH who have consistently elevated levels of low-density lipoprotein cholesterol (LDL-C) despite maximally tolerated statin therapy, current lipid guidelines recommend apheresis. Although apheresis reduces LDL-C levels by 50%-75%, it must be repeated, as frequently as every 1-2 weeks. OBJECTIVE: To assess clinical experience with apheresis and alirocumab for patients in a real-world practice setting. METHODS: This retrospective review included patients from 5 apheresis centers who were treated with apheresis and had started alirocumab therapy. In addition to LDL-C levels, total cholesterol, high-density lipoprotein cholesterol (HDL-C), non-HDL-C, triglycerides, and particle numbers were evaluated if data were available. RESULTS: Eleven of the 25 (44%) patients discontinued apheresis completely after initiation of alirocumab therapy, having achieved LDL-C \u3c70 mg/dL or \u3e50% reduction from baseline levels. Among the 14 patients who remained on apheresis, seven decreased the frequency of apheresis sessions. No significant safety problems were reported. CONCLUSION: Alirocumab lowered LDL-C levels by an average of 55.5% in patients receiving apheresis for elevated LDL-C. Seventy-two percent of patients on alirocumab therapy discontinued or reduced the frequency of apheresis treatment. However, some patients continued to require apheresis due to elevated lipoprotein(a), extremely elevated LDL-C, or if alirocumab therapy was discontinued due to less than anticipated LDL-C reduction

Computational Lipidology: Predicting Lipoprotein Density Profiles in Human Blood Plasma

Monitoring cholesterol levels is strongly recommended to identify patients at risk for myocardial infarction. However, clinical markers beyond “bad” and “good” cholesterol are needed to precisely predict individual lipid disorders. Our work contributes to this aim by bringing together experiment and theory. We developed a novel computer-based model of the human plasma lipoprotein metabolism in order to simulate the blood lipid levels in high resolution. Instead of focusing on a few conventionally used predefined lipoprotein density classes (LDL, HDL), we consider the entire protein and lipid composition spectrum of individual lipoprotein complexes. Subsequently, their distribution over density (which equals the lipoprotein profile) is calculated. As our main results, we (i) successfully reproduced clinically measured lipoprotein profiles of healthy subjects; (ii) assigned lipoproteins to narrow density classes, named high-resolution density sub-fractions (hrDS), revealing heterogeneous lipoprotein distributions within the major lipoprotein classes; and (iii) present model-based predictions of changes in the lipoprotein distribution elicited by disorders in underlying molecular processes. In its present state, the model offers a platform for many future applications aimed at understanding the reasons for inter-individual variability, identifying new sub-fractions of potential clinical relevance and a patient-oriented diagnosis of the potential molecular causes for individual dyslipidemia

Defective enzyme protein in lipoprotein lipase deficiency

A monoclonal antibody to lipoprotein lipase (LPL) has been used in an enzyme-linked immunosorbent assay (ELISA) for LPL protein mass. Measurement of LPL immunoreactive mass in pre- and postheparin plasma distinguished three classes of abnormalities in patients with classical deficiency of lipoprotein lipase activity. The class I defect consisted of the absence of LPL immunoreactive homodimer in pre- and postheparin plasma compatible with a potential 'null allele'. Patients with a class II defect had almost no LPL immunoreactive mass in preheparin plasma but showed an increase in their LPL mass of 68 +/- 23 ng ml-1 (mean +/- SD) after heparin. Patients with the class III defect had considerable amounts of LPL immunoreactive material in preheparin plasma (159 +/- 190 ng ml-1). Heparin administration, however, caused very little additional release of LPL into the plasma (16 +/- 51 ng ml-1). Thus although both class II and class III patients had an LPL protein with abnormal catalytic activity, class III patients also appeared to have a defect in heparin binding of LPL. To test this hypothesis, postheparin plasma of classes II and III patients was analysed by heparin-Sepharose chromatography. In contrast to class II patients, the LPL immunoreactive mass of class III patients did not show affinity for the heparin and eluted in the column void volume, suggesting the class III defect is also associated with a defect in heparin binding
