Abstract
Purpose of Review Lipoprotein apheresis is a very efficient but time-consuming and expensive method of lowering levels of low-density lipoprotein cholesterol, lipoprotein(a)) and other apoB containing lipoproteins, including triglyceride-rich lipoproteins. First introduced almost 45 years ago, it has long been a therapy of “last resort” for dyslipidaemias that cannot otherwise be managed. In recent years new, very potent lipid-lowering drugs have been developed and the purpose of this review is to define the role of lipoprotein apheresis in the current setting. Recent Findings Lipoprotein apheresis still plays an important role in managing patients with homozygous FH and some patients with other forms of hypercholesterolaemia and cardiovascular disease. In particular, patients not achieving treatment goals despite modern lipid-lowering drugs, either because these are not tolerated or the response is insufficient. Recently, lipoprotein(a) has emerged as an important cardiovascular risk factor and lipoprotein apheresis has been used to decrease lipoprotein(a) concentrations in patients with marked elevations and cardiovascular disease. However, there is considerable heterogeneity concerning the recommendations by scientific bodies as to which patient groups should be treated with lipoprotein apheresis. Summary Lipoprotein apheresis remains an important tool for the management of patients with severe drug-resistant dyslipidaemias, especially those with homozygous FH.

Abstract
BACKGROUND Lipoprotein apheresis effectively lowers lipoprotein(a) [Lp(a)] and low-density lipoprotein (LDL) by approximately 60%-70%. The rebound of LDL and Lp(a) particle concentrations following lipoprotein apheresis allows the determination of fractional catabolic rate (FCR) and hence production rate (PR) during non-steady state conditions. We aimed to investigate the kinetics of Lp(a) and LDL apolipoprotein B-100 (apoB) particles in patients with elevated Lp(a) and coronary artery disease undergoing regular apheresis. PATIENTS AND METHODS A cross-sectional study was carried out in 13 patients with elevated Lp(a) concentration (>500 mg/L) and coronary artery disease. Lp(a) and LDL-apoB metabolic parameters, including FCR and PR were derived by the fit of a compartment model to the Lp(a) and LDL-apoB concentration data following lipoprotein apheresis. RESULTS The FCR of Lp(a) was significantly lower than that of LDL-apoB (0.39 [0.31, 0.49] vs 0.57 [0.46, 0.71] pools/day, P = 0.03) with no significant differences in the corresponding PR (14.80 [11.34, 19.32] vs 15.73 [11.93, 20.75] mg/kg/day, P = 0.80). No significant associations were observed between the FCR and PR of Lp(a) and LDL-apoB. CONCLUSIONS In patients with elevated Lp(a), the fractional catabolism of Lp(a) is slower than that of LDL-apoB particles, implying that different metabolic pathways are involved in the catabolism of these lipoproteins. These findings have implications for new therapies for lowering apolipoprotein(a) and apoB to prevent atherosclerotic cardiovascular disease.

Abstract
Patients with diabetes mellitus have an elevated cardiovascular risk. Lipid-lowering therapy is a successful strategy to prevent atherosclerotic events in these patients. Therefore, almost all professional societies recommend statin therapy for patients with diabetes under certain conditions. Despite this broad consensus, a number of controversial issues remain. Thus, it remains unclear in which patients the lipid parameters should be determined in the fasting state and in which postprandial values are sufficient. It is also an open issue whether all patients with diabetes should receive statin therapy and which goals should be achieved. While the benefit of statin-ezetimibe and statin-PCSK9-inhibition combinations has been shown in large outcome trials, results of outcome trials involving statins with triglyceride lowering drugs have been ambiguous. Thus, it is currently unclear which patients benefit from such combinations. Finally, the best strategy to address severe hypertriglyceridemia in patients with diabetes is unclear. This article discusses these issues and aims to provide help and information to practicing physicians taking care of patients with diabetes mellitus. (REV INVEST CLIN. 2018;70:237-43).

Abstract
BACKGROUND AND AIMS It is unknown whether a school-based prevention program has the potential to improve microvascular health in children. This study investigates the impact of the school-based lifestyle intervention program JuvenTUM 3 on physical activity, physical fitness, serum biomarkers and microvascular function. METHODS We studied 434 children (10-11 years) in a cluster-randomized setting (8 intervention schools, IG; 7 control schools, CG) over 18 months. The school-based prevention program included weekly lifestyle lessons for children with the aim to increase physical activity in and outside of school, physical fitness as well as health behavior. Anthropometric measurements and blood sampling were conducted using standard protocols, physical activity by use of a questionnaire and physical fitness by a 6-item-test battery. Central retinal arteriolar (CRAE) and venular (CRVE) vessel diameters as early marker of vascular dysfunction, as well as the arteriolar-to-venular diameter ratio (AVR), were investigated with a non-mydriatic vessel analyser. RESULTS School-based physical activity increased in 41% of children in IG (19% in CG, p = 0.038). Improvements in vascular parameters were observed for AVR (increase in 83% of children in IG versus 50% in CG; p < 0.001) and for CRVE (43% of children with retinal venular widening in IG versus 58% in CG, p = 0.019). These vascular improvements were also seen in overweight children for CRAE (p = 0.021) and AVR (p < 0.001). CONCLUSIONS The school-based prevention program JuvenTUM 3 increased physical activity at school inducing favourable effects on retinal microvasculature function. These findings underline the importance of early lifestyle interventions in children for primary prevention of cardiovascular disease.

Abstract
BACKGROUND The obesity epidemic has continued to spread across the globe involving even poor nations of the world. METHOD Household population survey of adults aged 20-60 years. Multistage stratified cluster randomised sampling involving both urban and rural statewide representative population samples. Anthropometric measurements were taken using standard methods. Prevalences were weighted and multinomial regression analyses were done. RESULTS A total of 6628 individuals from 2843 households were surveyed. The weighted overall prevalence for underweight was 9.1% (95% CI 8.1 to 10.1), 65.1% (95% CI 63.6 to 66.6) for normal weight, 19.0% (95% CI 17.8 to 20.3) for overweight and 6.8% (95% CI 6.0 to 7.5) for obese. Men were less likely to be overweight (adjusted OR (AOR) 0.79; 95% CI 0.68 to 0.92) and obese (AOR 0.24; 95% CI 0.19 to 0.31) than women. Urban residents were more likely to be overweight (AOR 1.42; 95% CI 1.18 to 1.71) and obese (AOR 2.09; 95% CI 1.58 to 2.76) than rural residents. Each additional 1-year increase in age increased the risk of overweight by 1.012 (AOR 1.012; 95% CI 1.005 to 1.018) and that of obesity by 1.03 (AOR 1.03; 95% CI 1.02 to 1.04). The low-income class was less likely to be overweight (AOR 0.694; 95% CI 0.507 to 0.951) and obese (AOR 0.44; 95% CI 0.28 to 0.67). CONCLUSION The prevalence of obesity and overweight in Enugu Nigeria is high and fast approaching that of underweight. Women, urban dwellers, older adults and high-income earners are at higher risk for obesity and overweight. The study provides robust information for public health policies towards the prevention of obesity in Nigeria.

Abstract
OBJECTIVE PANORAMA, a nine-country cross-sectional type 2 diabetes study, investigated factors associated with quality of life (QoL), health status, and other patient-reported outcome measures (PROMs). RESEARCH DESIGN AND METHODS Patients were randomly or consecutively selected from primary/secondary care. PROMs included the Audit of Diabetes-Dependent Quality of Life (ADDQoL) (generic QoL item and average weighted impact [AWI] scores), Diabetes Treatment Satisfaction Questionnaire (DTSQ) (patient- and physician-completed), Hypoglycemia Fear Survey-II worry subscale, and the EuroQoL-5 Dimension visual analog scale (EQ-VAS) measuring patient-reported health. Multivariable linear regression analyses determined predictors of each PROM including patient characteristics, physician-reported adherence, complications, and glycosylated hemoglobin. RESULTS In 5,813 patients, mean PROM scores indicated that generic QoL approximated "good" (0.93); perceived impact of diabetes on QoL was negative (AWI -1.69). Treatment satisfaction exceeded physicians' estimates (patient-reported: 29.76; physician-estimated: 27.75), but so did patients' perceived frequency of hypo-/hyperglycemia. Worry about hypoglycemia (13.27) was apparent. Intensifying treatments to three oral agents or insulin regimens predicted worse QoL (AWI P < 0.01). Insulin alone use predicted worse QoL (generic P < 0.02; AWI P < 0.001) and hypoglycemia worry (P < 0.007). No treatment had significant associations with EQ-VAS health status. CONCLUSIONS Predictors for different PROMs differed markedly and provided insights for understanding and improving these important outcomes. Intensive treatment regimens had significant negative associations with all PROMs, except the EQ-VAS health status measure. The findings demonstrate the importance of measuring QoL alongside health status and other patient-reported outcomes when evaluating diabetes treatments with a view to protecting QoL and facilitating adherence and long-term glycemic control.

Abstract
PURPOSE OF REVIEW Although lipid-lowering treatment with statins, ezetimibe, and PCSK9 inhibitors is a very successful strategy to prevent cardiovascular events, there is a need for further drug developments. Not all patients respond sufficiently to the available therapy (very high baseline values, intolerance). Furthermore, patients may be characterized by dyslipidemias not accessible to available drugs such as patients with homozygous familial hypercholesterolemia, chylomicronemia syndrome, or elevated lipoprotein(a). A number of drugs are being developed to close these gaps. RECENT FINDINGS The focus is on new antibodies, antisense oligonucleotides, and small molecules that address different aspects of lipid metabolism. Many of these developments are promising as they decrease LDL-cholesterol and/or non-HDL-cholesterol and/or triglycerides and/or lipoprotein(a) in patients who so far cannot be treated sufficiently. These drugs are currently in different stages of development and being tested in clinical trials. SUMMARY Some of the new lipid-lowering drugs have a very promising profile. However, eventually phase 3 and outcome trials will be required to prove the usefulness of these compounds in clinical practice. Furthermore, it is unlikely that they will change the primary lipidological approach (statin and ezetimibe) even if they prove successful.

A Walnut-Enriched Diet Reduces Lipids in Healthy Caucasian Subjects, Independent of Recommended Macronutrient Replacement and Time Point of Consumption: a Prospective, Randomized, Controlled Trial. Nutrients 2017; 9:E1097.

Abstract
Studies indicate a positive association between walnut intake and improvements in plasma lipids. We evaluated the effect of an isocaloric replacement of macronutrients with walnuts and the time point of consumption on plasma lipids. We included 194 healthy subjects (134 females, age 63 ± 7 years, BMI 25.1 ± 4.0 kg/m²) in a randomized, controlled, prospective, cross-over study. Following a nut-free run-in period, subjects were randomized to two diet phases (8 weeks each). Ninety-six subjects first followed a walnut-enriched diet (43 g walnuts/day) and then switched to a nut-free diet. Ninety-eight subjects followed the diets in reverse order. Subjects were also randomized to either reduce carbohydrates (n = 62), fat (n = 65), or both (n = 67) during the walnut diet, and instructed to consume walnuts either as a meal or as a snack. The walnut diet resulted in a significant reduction in fasting cholesterol (walnut vs. CONTROL -8.5 ± 37.2 vs. -1.1 ± 35.4 mg/dL; p = 0.002), non-HDL cholesterol (-10.3 ± 35.5 vs. -1.4 ± 33.1 mg/dL; p ≤ 0.001), LDL-cholesterol (-7.4 ± 32.4 vs. -1.7 ± 29.7 mg/dL; p = 0.029), triglycerides (-5.0 ± 47.5 vs. 3.7 ± 48.5 mg/dL; p = 0.015) and apoB (-6.7 ± 22.4 vs. -0.5 ± 37.7; p ≤ 0.001), while HDL-cholesterol and lipoprotein (a) did not change significantly. Neither macronutrient replacement nor time point of consumption significantly affected the effect of walnuts on lipids. Thus, 43 g walnuts/d improved the lipid profile independent of the recommended macronutrient replacement and the time point of consumption.
