Abstract Objectives To assess whether the long-term separate ingestions of an encapsulated juice powder concentrate and a plant-based omega fatty acid supplement, or a combined ingestion of the two, can affect biomarkers of cardiovascular health, low-grade inflammation and indicators of aging in the elderly. Methods This is a randomised, controlled, open-labelled, parallel-grouped clinical trial, consisting of 4 arms. One hundred and twelve, overweight and obese (BMI 25–35 kg/m2) subjects, aged 60 to 80 years will be recruited and randomly allocated to: i) control group; ii) Fruit, Vegetable and Berry (FVB) group, where participants have to ingest a fruit, vegetable and berry supplement (Juice Plus+® capsules); iii) Omega group, where participants have to ingest a plant-based fatty acid supplement (Juice Plus+® Omega Blend); and iv) Fruit, Vegetable, Berry and Omega (FVBO) group, where participants have to ingest the fruit, vegetable and berry supplement, together with the plant-based fatty acid supplement. Participants in all groups will continue their habitual diet and lifestyle. Those allocated to one of the three intervention groups, will be asked to ingest the supplements for a total duration of two years. Participants will be assessed at baseline and at follow-up visits at 6, 12, 18 and 24 months. Primary outcomes include markers of cardiovascular health and low-grade inflammation. Secondary outcomes include selected indicators of aging, cognitive function, immunity and quality of life. Finally, plasma levels of vitamins, carotenoids and fatty acids will also be assessed. Results N/A Conclusions This study will provide evidence whether long-term, plant-based dietary supplementation can support cardiovascular health, anti-inflammatory processes, immunity and nutritional status in aging.

Abstract Objectives Via a randomized controlled clinical trial we evaluated whether 0.5 g or 1 g of omega-3-fatty acids from a plant-based food supplement (Juice Plus+® OMEGA Blend) could increase erythrocyte omega-3-index in healthy adult subjects. Methods After a 4-week wash out from food supplements and a 4-week run in to harmonize intake of dietary w-3 fatty acids, we conducted a controlled, randomized, open-labelled, parallel-grouped, clinical trial. 80 healthy adults from Austria, Europe, were randomized to four groups: a) control group, just adhering to the habitual diet; b) two capsules/day of the plant-based fatty acid supplement matching 0.5 g of w-3-fatty acids; c) four capsules/day of the plant-based fatty acid supplement matching 1 g of w-3-fatty acids; and d) four capsules of the plant-based fatty acid supplement and 6 capsules/day of a powdered, encapsulated, fruit, berry and vegetable juice concentrate (Juice Plus+® PREMIUM). Blood samples were collected at baseline, after 8 weeks, and after 16 weeks intervention with the food supplement(s). Results 68 subjects (39.43 ± 12.28 years, 33 female, 35 male) completed the intervention. Baseline data on w-3-index revealed that the average w-3-index of the investigated groups was already higher than expected (mean value: 7.8%). Nevertheless, the intervention with the commercially available and plant-based fatty acid food supplement increased erythrocyte w-3-index significantly in all intervention groups (p < 0.001), after 8 weeks (mean values increased from 7.8% into a range from 10.4% to 11.1%) as well as after 16 weeks (mean values increased from 7.8% into a range from 11.7% to 14.4%). In all intervention groups the w-3-index was also significantly different from control (p < 0.001), after 8 weeks as well as after 16 weeks. No significant differences in w-3-index were detected between intervention groups after 8 and 16 weeks. Conclusions These data demonstrate that the intake of only 0.5 g/day of a plant-based w-3 fatty acid food supplement from algae and berry seeds is able to increase the w-3-index of a well-nourished, healthy cohort significantly only after 8 weeks.

Gestational diabetes mellitus (GDM) is the most common pregnancy-associated metabolic disorder that negatively impacts on the health of both mothers and their offspring in the long-term. The molecular mechanisms involved are not fully understood. As in other states of insulin resistance, a disproportionate immune response in GDM leads to a state of chronic low-grade inflammation. Galectin-2 exerts regulatory effects on different immune cells. This study investigated galectin-2 expression in the placenta of 40 GDM patients and 40 controls, in a sex-specific manner. Immunohistochemistry was used for semi-quantitative analysis of expression strength. The phenotypes of galectin-2 expressing cells were characterized through double immunofluorescence. We found a significant up-regulation of galectin-2 in the fetal syncytiotrophoblast, as well as in the maternal decidua of GDM placentas. Double staining showed a strong galectin-2 expression in extra villous trophoblast cells and fetal endothelial cells in GDM. These findings present the first systematic investigation of galectin-2 in GDM. The findings contribute to the emerging understanding of the role of immunomodulation and inflammation in GDM and of galectin-2 itself. This might also have implications for the long-term cardiovascular health of the offspring.

AbstractEnhanced follow-up is needed to improve the results of secondary preventive care in patients with established cardiovascular disease. We examined the effect of long-term, nurse-based, secondary preventive follow-up by telephone on the recurrence of cardiovascular events. Open, randomised, controlled trial with two parallel groups. Between 1 January 2010 and 31 December 2014, consecutive patients (n = 1890) admitted to hospital due to stroke, transient ischaemic attack (TIA), or acute coronary syndrome (ACS) were included. Participants were randomised (1:1) to nurse-based telephone follow-up (intervention, n = 944) or usual care (control, n = 946) and followed until 31 December 2017. The primary endpoint was a composite of stroke, myocardial infarction, cardiac revascularisation, and cardiovascular death. The individual components of the primary endpoint, TIA, and all-cause mortality were analysed as secondary endpoints. The assessment of outcome events was blinded to study group assignment. After a mean follow-up of 4.5 years, 22.7% (n = 214) of patients in the intervention group and 27.1% (n = 256) in the control group reached the primary composite endpoint (HR 0.81, 95% CI 0.68–0.97; ARR 4.4%, 95% CI 0.5–8.3). Secondary endpoints did not differ significantly between groups. Nurse-based secondary preventive follow-up by telephone reduced the recurrence of cardiovascular events during long-term follow-up.

Background: Several cytochrome P450 (CYP) enzyme families have been identified in extra hepatic tissues such as heart, vasculature, kidney, and lung. CYP2C19 localized in vascular smooth muscle and endothelium contributes to the regulation of vascular tone and homeostasis. However, it is unknown whether CYP2C19 genotype is associated with the vascular tonus in patients with VSA. The aim of this study was to examine the impact of CYP2C19 genotype on coronary artery spasm in patients with VSA. Methods: We examined the distribution of CYP2C19 genotype in patients with VSA (n=129) who were diagnosed by intra-coronary acetylcholine infusion test and healthy subjects (n=455) as control group. CYP2C19 genotypes were divided into 3 groups; (1) CYP2C19*1/*1: EM, (2) one loss-of-function allele (*1/*2, *1/*3: IM), and (3) two loss-of-function alleles (*2/*2, *2/*3, *3/*3: PM). Moreover, we measured the level of high-sensitive CRP (hs-CRP) as a degree of low glade inflammation in each group. Results: The ratios of CYP2C19 genotype (EM, IM, and PM) were 30, 42, and 28% in VSA group, and 32, 49, and 19% in control group. In short, PM frequency was significantly higher in VSA than in control (28% vs 19%, P=0.026). In VSA group, the ratios of CYP2C19 genotype were 36, 44, and 20% in male, and 20, 39, and 41% in female, respectively. Briefly, the PM frequency was significantly higher in female than in male (41% vs 20%, P<0.001). Moreover, the level of hs-CRP was significantly higher in VSA group than in control group (0.17±0.367 vs 0.10.±0.240, P=0.02). When patients were stratified by gender, the level of hs-CRP was significantly higher in VSA group in female (0.11±0.198 vs 0.06±0.105, P=0.031) and male (0.20±0.438 vs 0.12±0.277, P=0.044). Multivariate analysis for coronary spasm indicated high age, hypertension, and high level of hs-CRP as predictive factors among all subjects. PM is a predictive factor for coronary spasm in female group only (OR3.1, 95%RI 1.525-6.317, P=0.002), but not in male (OR0.829, 95%RI 0.453-1.518, P=0.543). Conclusion: The CYP2C19 two loss-of-function alleles (PM) and low grade inflammation may be associated with pathophysiology of coronary artery spasm and the regulation of coronary tonus, especially in female.

AbstractObjective To determine the effects of training on the quality of peer review.Design Single blind randomised controlled trial with two intervention groups receiving different types of training plus a control group.Setting and participants Reviewers at a general medical journal.Interventions Attendance at a training workshop or reception of a self taught training package focusing on what editors want from reviewers and how to critically appraise randomised controlled trials.Main outcome measures Quality of reviews of three manuscripts sent to reviewers at four to six monthly intervals, evaluated using the validated review quality instrument; number of deliberate major errors identified; time taken to review the manuscripts; proportion recommending rejection of the manuscripts.Results Reviewers in the self taught group scored higher in review quality after training than did the control group (score 2.85 v 2.56; difference 0.29, 95% confidence interval 0.14 to 0.44; P = 0.001), but the difference was not of editorial significance and was not maintained in the long term. Both intervention groups identified significantly more major errors after training than did the control group (3.14 and 2.96 v 2.13; P < 0.001), and this remained significant after the reviewers' performance at baseline assessment was taken into account. The evidence for benefit of training was no longer apparent on further testing six months after the interventions. Training had no impact on the time taken to review the papers but was associated with an increased likelihood of recommending rejection (92% and 84% v 76%; P = 0.002).Conclusions Short training packages have only a slight impact on the quality of peer review. The value of longer interventions needs to be assessed.

High-fat diet (HFD) consumption has been linked to dyslipidemia, low-grade inflammation and oxidative stress. This study investigated the effects of a mixed formulation with Limosilactobacillusfermentum 139, L. fermentum 263 and L. fermentum 296 on cardiometabolic parameters, fecal short-chain fatty acid (SCFA) contents and biomarkers of inflammation and oxidative stress in colon and heart tissues of male rats fed an HFD. Male Wistar rats were grouped into control diet (CTL, n = 6), HFD (n = 6) and HFD with L. fermentum formulation (HFD-Lf, n = 6) groups. The L.fermentum formulation (1 × 109 CFU/mL of each strain) was administered twice a day for 4 weeks. After a 4-week follow-up, biochemical parameters, fecal SCFA, cytokines and oxidative stress variables were evaluated. HFD consumption caused hyperlipidemia, hyperglycemia, low-grade inflammation, reduced fecal acetate and propionate contents and increased biomarkers of oxidative stress in colon and heart tissues when compared to the CTL group. Rats receiving the L. fermentum formulation had reduced hyperlipidemia and hyperglycemia, but similar SCFA contents in comparison with the HFD group (p < 0.05). Rats receiving the L. fermentum formulation had increased antioxidant capacity throughout the colon and heart tissues when compared with the control group. Administration of a mixed L. fermentum formulation prevented hyperlipidemia, inflammation and oxidative stress in colon and heart tissues induced by HFD consumption.

Increased Susceptibility

Biomarkers of low-grade inflammation have been associated with susceptibility to a severe infectious disease course, even when measured prior to disease onset. We investigated whether metabolic biomarkers measured by nuclear magnetic resonance (NMR) spectroscopy could be associated with susceptibility to severe pneumonia (2507 hospitalised or fatal cases) and severe COVID-19 (652 hospitalised cases) in 105,146 generally healthy individuals from UK Biobank, with blood samples collected 2007–2010. The overall signature of metabolic biomarker associations was similar for the risk of severe pneumonia and severe COVID-19. A multi-biomarker score, comprised of 25 proteins, fatty acids, amino acids and lipids, was associated equally strongly with enhanced susceptibility to severe COVID-19 (odds ratio 2.9 [95%CI 2.1–3.8] for highest vs lowest quintile) and severe pneumonia events occurring 7–11 years after blood sampling (2.6 [1.7–3.9]). However, the risk for severe pneumonia occurring during the first 2 years after blood sampling for people with elevated levels of the multi-biomarker score was over four times higher than for long-term risk (8.0 [4.1–15.6]). If these hypothesis generating findings on increased susceptibility to severe pneumonia during the first few years after blood sampling extend to severe COVID-19, metabolic biomarker profiling could potentially complement existing tools for identifying individuals at high risk. These results provide novel molecular understanding on how metabolic biomarkers reflect the susceptibility to severe COVID-19 and other infections in the general population.
