OBJECTIVE: In 2016, France allowed men who have sex with men (MSM) to donate blood if they had not had sex with men in the previous 12 months. In April 2020, this restriction was relaxed to 4 months due to the lack of negative impact observed on blood safety. This study assesses the impact of reducing this deferral period on epidemiological surveillance indicators.
METHODS: This study compares infection surveillance indicators between two 30-month periods before (P1) and after (P2) this second deferral change.
RESULTS: Overall, 79 donations tested positive for human immunodeficiency virus (HIV) (49 in P1 and 30 in P2), 322 for hepatitis C virus (HCV) (185 and 137), 622 for hepatitis B virus (HBV) (355 and 267) and 1684 for syphilis (799 and 885). Positive donation rates decreased between P1 and P2, except for syphilis: HIV (0.07/10,000 donations vs. 0.04; p > 0.5), HCV (0.25 vs. 0.20; p < 0.05), HBV (0.49 vs. 0.39; p < 0.01) and syphilis (1.10 vs. 1.29; p < 0.001). For all three viruses, residual risks of transmission by transfusion did not increase: HIV (1/7,800,000 donations vs. 1/10,500,000), HCV (1/25,200,000 vs. 1/47,300,000) and HBV (1/6,400,000 vs. 1/6,000,000).
CONCLUSIONS: Reducing the deferral period for MSM in April 2020 did not negatively impact residual risks, which remained very low, or the rate of positive donations, except for syphilis, which requires careful monitoring. To ensure equal access to blood donation, MSM have been allowed to donate blood under the same conditions as other donors since March 2022 (i.e., no more than one sexual partner in the last 4 months).

UNASSIGNED: Historically, atherosclerotic cardiovascular disease (ASCVD) risk profile mitigation has had a predominant focus on low density lipoprotein cholesterol (LDL-C). In this narrative review we explore the residual ASCVD risk profile beyond LDL-C with a focus on hypertriglyceridaemia, recent clinical trials of therapeutics targeting hypertriglyceridaemia and novel modalities addressing other residual ASCVD risk factors.
UNASSIGNED: Hypertriglyceridaemia remains a significant ASCVD risk despite low LDL-C in statin or proprotein convertase subtilisin/kexin type 9 inhibitor-treated patients. Large population-based observational studies have consistently demonstrated an association between hypertriglyceridaemia with ASCVD. This relationship is complicated by the co-existence of low high-density lipoprotein cholesterol. Despite significantly improving atherogenic dyslipidaemia, the most recent clinical trial outcome has cast doubt on the utility of pharmacologically lowering triglyceride concentrations using fibrates. On the other hand, purified eicosapentaenoic acid (EPA), but not in combination with docosahexaenoic acid (DHA), has produced favourable ASCVD outcomes. The outcome of these trials suggests alternate pathways involved in ASCVD risk modulation. Several other pharmacotherapies have been proposed to address other ASCVD risk factors targeting inflammation, thrombotic and metabolic factors.
UNASSIGNED: Hypertriglyceridaemia poses a significant residual ASCVD risk in patients already on LDL-C lowering therapy. Results from pharmacologically lowering triglyceride are conflicting. The role of fibrates and combination of EPA and DHA is under question but there is now convincing evidence of ASCVD risk reduction with pure EPA in a subgroup of patients with hypertriglyceridaemia. Clinical guidelines should be updated in line with recent clinical trials evidence. Novel agents targeting non-conventional ASCVD risks need further evaluation.

On average, LDL particles are the most populous lipoprotein in serum under fasting conditions. For many reasons, it has been the primary target of lipid-lowering guidelines around the world. In the past 30 years, we have witnessed remarkable changes in each iteration of dyslipidaemia guidelines, with LDL-cholesterol (LDL-C) targets becoming lower and lower among patients at high and very high risk for atherosclerotic cardiovascular disease (ASCVD). The world over, goal attainment rates are low, and hence, ASCVD prevalence remains unacceptably high. Inadequate LDL-C lowering is a major issue in contemporary cardiovascular (CV) medicine. Another issue that vexes even the most astute clinician is that of \'residual risk\', meaning the excess risk that remains even after LDL-C is appropriately reduced. In recent years, an important new component of residual risk has emerged: triglyceride-enriched lipoproteins or remnant lipoproteins. These precursors to LDL particles can assume outsized importance among patients with derangements in triglyceride metabolism (e.g. genetic variants, insulin resistance, and diabetes mellitus) and may be more atherogenic than LDL species. Consequently, to reduce total risk for acute CV events, the time has come to include the entire spectrum of apoB-containing lipoproteins in approaches to both risk evaluation and treatment.

UNASSIGNED: The prognostic implications of persistent low-grade inflammation in patients with chronic coronary syndrome (CCS) are underexplored. The REAL-CAD (Randomized Evaluation of Aggressive or Moderate Lipid Lowering Therapy with Pitavastatin in Coronary Artery Disease) study demonstrated the benefit of higher intensity pitavastatin in Japanese patients with CCS.
UNASSIGNED: This prespecified subanalysis of the REAL-CAD study aimed to assess the prognostic effect of the persistent low-grade inflammation represented by high-sensitivity C-reactive protein (hs-CRP) in CCS patients.
UNASSIGNED: The present analysis involved patients without events until 6 months after randomization and whose hs-CRP levels were available at baseline and 6 months (n = 10,460). The primary endpoint was the composite of cardiovascular mortality, myocardial infarction, stroke, and unstable angina hospitalization. Landmark analyses evaluated the prognostic impact of continuous inflammation in 4 groups based on the median levels of hs-CRP (0.5 mg/L for both) at baseline and 6 months. The 4 groups included patient with persistently low, elevated (increased), reduced, and persistently high hs-CRP.
UNASSIGNED: Adjusted Cox proportional hazard analyses demonstrated an increased risk of the primary endpoint in the group with persistently high hs-CRP when compared to the group with persistently low hs-CRP as a reference (adjusted HR: 1.48, 95% CI: 1.18-1.89; P = 0.001), but with a similar risk in the group with elevated (HR: 1.07, 95% CI: 0.77-1.49, P = 0.68) and reduced (HR: 0.92; 95% CI: 0.66-1.27; P = 0.60) hs-CRP.
UNASSIGNED: The study shows that persistent low-grade inflammation is associated with poor outcomes and underscores the need to address residual inflammatory risk in CCS patients. (Randomized Evaluation of Aggressive or Moderate Lipid Lowering Therapy With Pitavastatin in Coronary Artery Disease [REAL-CAD]; NCT01042730).

UNASSIGNED: Lipid-related risk and residual cardiovascular risk remain high in patients with type 2 diabetes (T2D) and atherosclerotic cardiovascular disease (ASCVD). Significant treatment gaps exist in implementation of pluripotent and effective therapies that reduce these risks.
UNASSIGNED: This study evaluates the efficacy and impact of a dedicated, standalone cardiometabolic clinic designed to address treatment gaps through streamlined management and optimization of treatment strategies.
UNASSIGNED: We retrospectively collected data from the first 400 patients with T2D and ASCVD who underwent treatment at the clinic and presented for at least one follow-up visit. These patients were primarily managed for their cardiometabolic risks and received intensified lipid-lowering therapies, including adjunct non-statin therapies.
UNASSIGNED: Significant findings included increased use of glucagon-like peptide-1 receptor agonists (GLP1RA) and sodium-glucose cotransporter 2 inhibitors (SGLT2i) to 84 % and 65 %, respectively, with 94 % of patients eventually on one therapy and 55 % on dual therapy. Increases in lipid-lowering therapies led to 89 % of patients achieving low-density lipoprotein cholesterol levels below patient-specific thresholds for intensification.
UNASSIGNED: This care model effectively manages high-risk patient needs, achieving significant intensification of lipid-lowering therapies and broad use of cardiometabolic drugs, and highlights the clinic\'s potential to serve as a model for similar high-risk populations.

Salmonella in raw cocoa beans (n = 870) from main sourcing areas over nine months was analyzed. It was detected in 71 (ca. 8.2%) samples, with a contamination level of 0.3-46 MPN/g except for one sample (4.1 × 104 CFU/g). Using prevalence and concentration data as input, the impact of thermal treatment in cocoa processing on the risk estimate of acquiring salmonellosis by a random Belgian chocolate consumer was calculated by a quantitative microbiological risk assessment (QMRA) approach. A modular process risk model from raw cocoa beans to cocoa liquor up to a hypothetical final product (70-90% dark chocolate tablet) was set up to understand changes in Salmonella concentrations following the production process. Different thermal treatments during bean or nib steam, nib roasting, or liquor sterilization (achieving a 0-6 log reduction of Salmonella) were simulated. Based on the generic FAO/WHO Salmonella dose-response model and the chocolate consumption data in Belgium, salmonellosis risk per serving and cases per year at population level were estimated. When a 5 log reduction of Salmonella was achieved, the estimated mean risk per serving was 3.35 × 10-8 (95% CI: 3.27 × 10-10-1.59 × 10-7), and estimated salmonellosis cases per year (11.7 million population) was 88 (95% CI: <1-418). The estimated mean risk per serving was 3.35 × 10-9 (95% CI: 3.27 × 10-11-1.59 × 10-8), and the estimated salmonellosis cases per year was 9 (95% CI: <1-42), for a 6 log reduction. The current QMRA model solely considered Salmonella reduction in a single-step thermal treatment in the cocoa process. Inactivation obtained during other process steps (e.g. grinding) might occur but was not considered. As the purpose was to use QMRA as a tool to evaluate the log reduction in the cocoa processing, no postcontamination from the processing environment and ingredients was included. A minimum of 5 log reduction of Salmonella in the single-step thermal treatment of cocoa process was considered to be adequate.

OBJECTIVE: Currently little is known about the joint association of lipoprotein (a) [Lp(a)] and Lipoprotein-associated phospholipase A2 (Lp-PLA2) with stroke recurrence.
METHODS: In this prospective multicenter cohort study, 10,675 consecutive acute ischemic stroke (IS) and transient ischemic attack patients (TIA) with Lp(a) and Lp-PLA2 were enrolled. The association of stroke recurrence within 1 year with Lp(a) and Lp-PLA2 was assessed using Cox proportional hazards models and Kaplan-Meier curves. The interaction between Lp(a) and Lp-PLA2 with stroke recurrence was evaluated by multiplicative and additive scales.
RESULTS: A significant joint association of Lp(a) and Lp-PLA2 with the risk of stroke recurrence was observed. Multivariate cox regression analysis demonstrated that the combination of elevated Lp(a) (≥ 50 mg/dL) and Lp-PLA2 (≥175.1 ng/ml) was independently associated with the risk of stroke recurrence (adjusted hazard ratio: 1.42; 95 % CI: 1.15-1.76). Both significant multiplicative [(exp(β3):1.63, 95 % CI: 1.17-2.29, P = 0.004] and additive interaction (RERI:0.55, 95 % CI: 0.20-0.90, P = 0.002; AP: 0.39, 95 %CI, 0.24-0.53) were observed between Lp(a) and Lp-PLA2.
CONCLUSIONS: Our results indicated that Lp(a) and Lp-PLA2 have a joint association with the risk of stroke recurrence in IS/TIA patients. Patients with concomitant presence of elevated Lp(a) and Lp-PLA2 have greater risk of stroke recurrence.

Quadruple therapy is effective for patients with heart failure with reduced ejection fraction, providing significant clinical benefits, including reduced mortality. Clinicians are now in an era focused on how to initiate and titrate quadrable therapy in the early phase of the disease trajectory, including during heart failure hospitalization. However, patients with heart failure with reduced ejection fraction still face a significant \"residual risk\" of mortality and heart failure hospitalization. Despite the effective implementation of quadruple therapy, high mortality and rehospitalization rates persist in heart failure with reduced ejection fraction, and many patients cannot maximize therapy due to side effects such as hypotension and renal dysfunction. In this context, ivabradine, vericiguat, and omecamtiv mecarbil may have adjunct roles in addition to quadruple therapy (note that omecamtiv mecarbil is not currently approved for clinical use). However, the contemporary use of ivabradine and vericiguat is relatively low globally, likely due in part to the under-recognition of the role of these therapies as well as costs. This review offers clinicians a straightforward guide for bedside evaluation of potential candidates for these medications. Quadruple therapy, with strong evidence to reduce mortality, should always be prioritized for implementation. As second-line therapies, ivabradine could be considered for patients who cannot achieve optimal heart rate control (≥ 70 bpm at rest) despite maximally tolerated beta-blocker dosing. Vericiguat could be considered for high-risk patients who have recently experienced worsening heart failure events despite being on quadrable therapy, but they should not have N-terminal pro-B-type natriuretic peptide levels exceeding 8000 pg/mL. In the future, omecamtiv mecarbil may be considered for severe heart failure (New York Heart Association class III to IV, ejection fraction ≤ 30%, and heart failure hospitalization within 6 months) when current quadrable therapy is limited, although this is still hypothesis-generating and requires further investigation before its approval.

UNASSIGNED: In the SPARCL (Stroke Prevention by Aggressive Reduction in Cholesterol levels) trial, atorvastatin (80 mg/d) was compared to placebo in patients with recent stroke or transient ischemic attack (TIA) and no known coronary artery disease.
UNASSIGNED: This study aimed to assess the contribution of lipoprotein(a) [Lp(a)] to subsequent cerebrovascular and cardiovascular events in stroke/TIA survivors.
UNASSIGNED: Lp(a) levels and apolipoprotein(a) [apo(a)] isoform size were determined by liquid-chromatography mass spectrometry in samples collected at baseline from 2,814 SPARCL participants (1,418 randomized to atorvastatin and 1,396 to placebo). Within each treatment arm, patients in the highest quartile (≥84.0 nmol/L) were compared with those in the lowest quartiles of Lp(a) concentrations. Patients in the lowest quartile (≤25.9 Kringle IV domains) of apo(a) isoform sizes were compared with those in the highest quartiles. Multivariable-adjusted HRs were calculated using Cox proportional regression models.
UNASSIGNED: There was no significant association between Lp(a) concentrations or apo(a) isoform sizes and the risk of recurrent stroke, the primary outcome of SPARCL, or cerebrovascular events in patients randomized to atorvastatin or placebo. In contrast, in patients randomized to atorvastatin, elevated Lp(a) concentrations and short apo(a) isoforms were positively and independently associated with an increased risk of coronary events (HR: 1.607 [95% CI: 1.007-2.563] and HR: 2.052 [95% CI: 1.303-3.232]). No such association was found in patients randomized to placebo (HR: 1.025 [95% CI: 0.675-1.555] and HR: 1.097 [95% CI: 0.735-1.637]).
UNASSIGNED: Lp(a) contributes to the residual coronary artery disease risk of statin-treated stroke/TIA survivors, paving the way for use of therapies targeting Lp(a) in this population with stroke. (Lipitor In The Prevention Of Stroke, For Patients Who Have Had A Previous Stroke [SPARCL]; NCT00147602).
