Aim: Epidemiological evidence suggests adherence to vegetable-rich diets is associated to atheroprotective effects and bioactive components are most likely to play a relevant role. The notion of inter-kingdom regulation has opened a new research paradigm and perhaps microRNAs (miRNAs) from edible vegetables could influence consumer gene expression and lead to biological effects. We aimed to investigate the potential impact of broccoli-derived miRNAs on cellular cholesterol efflux in vitro.
Methods: Four miRNAs (miR159a, miR159b, miR166a and miR403) from Brassica oleracea var. italica (broccoli), a widely consumed cruciferous vegetable, were selected for further investigation, based on their high abundancy in this vegetable and their presence in other plants. Selected miRNAs were synthesized with a 3'-terminal 2'-O-methylation and their cellular toxicity, in vitro gastrointestinal resistance and cellular uptake were evaluated. Potential target genes within the mammalian transcriptome were assessed in silico following pathway analysis. In vitro cholesterol efflux was assessed in human THP-1-derived macrophages.
Results: miRNAs survival to in vitro GI digestion was around 1%, although some variation was seen between the four candidates. Cellular uptake by mammalian cells was confirmed, and an increase in cholesterol efflux was observed. Pathway analysis suggested these miRNAs are involved in biological processes related to phosphorylation, phosphatidylinositol and Wnt signaling, and to the insulin/IGF pathway.
Conclusions: Health-promoting properties attributed to cruciferous vegetables, might be mediated (at least in part) through miRNA-related mechanisms.

Diabetes, especially type 2, is considered a risk situation for atherosclerotic cardiovascular disease (ASCVD). Subjects with diabetes type 2 have a mortality rate due to ASCVD 3 times higher than that found in the general population, attributed to hyperglycemia and the frequent association of other cardiovascular risk factors, such as atherogenic dyslipidemia.
Numerous scientific societies have established a risk classification for ASCVD in diabetes based on 3 degrees (moderate, high and very high). The objectives of dyslipidemia control are clearly defined and accepted, and vary depending on the previously established cardiovascular risk.
In moderate or intermediate risk, the guidelines propose a less intensive intervention, maintaining LDL-C levels < 100 mg/dL and NO-HDL-C levels < 130 mg/dL, and waiting 10 years until reaching the high-risk category to initiate more intensive treatment. However, during the decade of follow-up recommended in the guidelines, cholesterol deposition in the arterial wall increases, facilitating the development of an unstable and inflammatory atheromatous plaque, and the development of ASCVD. Alternatively, diabetes could be considered from the outset to be a high-risk situation and the goal should be LDL-C < 70 mg/dL. Furthermore, maintaining LDL-C levels < 70 mg/dL contributes to reducing and stabilizing atheromatous plaque, avoiding or reducing mortality episodes due to ASCVD during those years of diabetes evolution.
Should we maintain the proposed objectives in subjects with diabetes and moderate risk for a decade until reaching the high cardiovascular risk phase or, on the contrary, should we adopt a more intensive stance from the beginning seeking to reduce cardiovascular risk in the majority of patients with diabetes? Is it better to wait or prevent with effective therapeutic measures from the first moment?

Multiple systematic reviews (SR) have been performed on the effects of proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i), often providing conflicting findings. This overview and network meta-analysis (NMA) aimed to summarize SR findings on the efficacy and safety of PCSK9i and provide an updated NMA.
Materials and methods
MEDLINE (Pubmed), Scopus, Cochrane, Epistemonikos and Google Scholar were searched from inception to September 21, 2023 for SRs of randomized controlled trials (RCTs) and from January 1, 2020 to September 21, 2023 for additional RCTs. Double-independent study selection, data extraction and quality assessment were performed. Qualitative analysis was performed for SRs and a frequentist random-effects model NMA was performed for RCTs.
Results
Totally, 86 SRs and 76 RCTs were included. Alirocumab (77/86 [90%]) and evolocumab (73/86 [85%]) were mostly analyzed. Associations from SRs (35/42 [83%]) and the updated NMA indicated PCSK9i benefit on major adverse cardiovascular events (MACEs). Reductions were also noted for cerebrovascular events (47/66 [71%]), coronary revascularization (29/33 [88%]) and myocardial infarction (41/63 [65%]). Alirocumab was associated with reductions on all-cause mortality (RR = 0.82, 95%CI [0.72,0.94]). Data on any CV event reduction were conflicting (7/16 [44%]). Inclisiran appeared effective only on MACEs (RR = 0.76, 95%CI [0.61,0.94]). No reductions in heart failure were observed (0/16). No increases were identified between PCSK9i and any (0/35) or serious adverse events (0/52). However, PCSK9i were associated with injection-site reactions (20/28 [71%]).
Conclusion
PCSK9i appeared to be effective in CV outcomes and their clinical application was generally safe.

Background
The aim of this study was to investigate presence of subclinical atherosclerosis by measuring carotid intima-media thickness (CIMT) in patients with Helicobacter pylori (HP) and to assess effects of HP on atherosclerosis by evaluating markers of atherosclerosis and blood growth differentiation factor (GDF-15) levels.
Materials and methods
This cross-sectional study included 59 patients without comorbid disease who had HP and 30 healthy controls without HP in upper endoscopic biopsy. In order to assess atherosclerosis, the CIMT measurement was performed by sonography. Serum GDF-15 level was measured by ELISA method. In all patients, atherosclerosis markers were recorded. Atherogenic indices were calculated, including Castelli risk index I and II (TG/HDL-c and LDL-c/HDL-c, respectively), plasma atherogenic index (PAI; log TG/HDL-c), non-HDL-c (TH-HDL-c) and atherogenic coefficient (AC; non-HDL-HDL-c).
Results
The GDF-15 level and CIMT were significantly higher in HP-positive group when compared to HP-negative group (p ≤ 0.001). There was a significant correlation between serum GDF-15 level and CIMT (r = 0.445; p ≤ 0.001). There was no correlation between other atherosclerosis markers and serum GDF-15 level or CIMT. The bacterial intensity on endoscopic specimen was only correlated with CIMT (p < 0.001). Vitamin B12 and D levels were comparable among groups.
Conclusion
This study suggested that there was a correlation between GDF-15 level and subclinical atherosclerosis development in patients with HP. However, GDF-15 level, which was found to be elevated while atherogenic indices were normal, can be an earlier marker for subclinical atherosclerosis.

Background
Recently, an inverse relationship between the blood concentration of lipoprotein(a) (Lp(a)) and triglycerides (TG) has been demonstrated. The larger the VLDL particle size, the greater the presence of VLDL rich in apoliprotein E and in subjects with the apoE2/E2 genotype, the lower Lp(a) concentration. The mechanism of this inverse association is unknown. The objective of this analysis was to evaluate the Lp(a)–TG association in patients treated at the lipid units included in the registry of the Spanish Society of Atherosclerosis (SEA) by comparing the different dyslipidemias.
Patients and methods
Five thousand two hundred and seventy-five subjects ≥18 years of age registered in the registry before March 31, 2023, with Lp(a) concentration data and complete lipid profile information without treatment were included.
Results
The mean age was 53.0 ± 14.0 years, with 48% women. The 9.5% of subjects (n = 502) had diabetes and the 22.4% (n = 1184) were obese. The median TG level was 130 mg/dL (IQR 88.0–210) and Lp(a) 55.0 nmol/L (IQR 17.9–156). Lp(a) concentration showed a negative association with TG concentration when TG values exceeded 300 mg/dL. Subjects with TG > 1000 mg/dL showed the lowest level of Lp(a), 17.9 nmol/L, and subjects with TG < 300 mg/dL had a mean Lp(a) concentration of 60.1 nmol/L. In subjects without diabetes or obesity, the inverse association of Lp(a)–TG was especially important (p < 0.001). The median Lp(a) was 58.3 nmol/L in those with TG < 300 mg/dL and 22.0 nmol/L if TG > 1000 mg/dL. No association was found between TG and Lp(a) in subjects with diabetes and obesity, nor in subjects with familial hypercholesterolemia. In subjects with multifactorial combined hyperlipemia with TG < 300 mg/dL, Lp(a) was 64.6 nmol/L; in the range of 300–399 mg/dL of TG, Lp(a) decreased to 38. 8 nmol/L, and up to 22.3 nmol/L when TG > 1000 mg/dL.
Conclusions
Our results show an inverse Lp(a)–TG relationship in TG concentrations > 300 mg/dL in subjects without diabetes, obesity and without familial hypercholesterolemia. Our results suggest that, in those hypertriglyceridemias due to hepatic overproduction of VLDL, the formation of Lp(a) is reduced, unlike those in which the peripheral catabolism of TG-rich lipoproteins is reduced.

Background
Combined oral contraceptives (COCs), use in individuals are associated with increased risk of thrombotic events. This highlights the significance of assessing the impact of COC on promoting coagulation and endothelial activation in high-fat diet (HFD)-fed Sprague Dawley rats.
Methods
Twenty (20) five-weeks-old female Sprague Dawley rats weighing between 150 and 200 g were subjected to both LFD and HFD-feeding for 8-weeks to determine its influence on basic metabolic status, hemostatic profile, hemodynamic parameters (blood pressure and heart rate), as well as selected biomarkers of coagulation (tissue factor and D-dimer) and endothelial activation (Von Willebrand factor and nitric oxide). Thereafter HFD-fed animals were treated with receive high dose combined oral contraceptive (HCOC) and low dose combine oral contraceptive (LCOC) for 6 weeks.
Results
Our results showed that beyond weight gain, HFD-feeding was associated with hyperglycemia, increased mean arterial pressure, and reduced nitric oxide levels when compared with LFD group (p < 0.05). Interestingly, treatment with high dose of COC for 6-weeks did not significantly alter atherothrombotic markers (p > 0.05). However, this study is not without limitation as regulation of these markers remains to be confirmed within the cardiac tissues or endothelial cells of these animals.
Conclusion
HFD-feeding orchestrate the concomitant release of pro-coagulants and endothelial activation markers in rats leading to haemostatic imbalance and endothelial dysfunction. Short-term treatment with COC shows no detrimental effects in these HFD-fed rats. Although in terms of clinical relevance, our findings depict the notion that the risk of CVD in association with COC may depend on the dosage and duration of use among other factors especially in certain conditions. However, additional studies are required to confirm these findings, especially long-term effects of this treatment within the cardiac tissues or endothelial cells of these animals in certain conditions relating to postmenopausal state.

Background
Cardiovascular disease (CVD) represents the primary cause of death and disability globally, with elevated cholesterol as one of the leading risk factors for CVD. We describe the clinical characteristics, treatment patterns, and effectiveness of evolocumab in treating hyperlipidemia.
Methods
Observational study conducted through a chart review of patients with hyperlipidemia receiving evolocumab as part of clinical management in Colombia.
Results
This study included 115 patients treated with evolocumab. A total of 101 patients (87.8%) had a history of CVD, 13 (11.3%) familial hypercholesterolemia (FH), and 23 (20%) type 2 diabetes. Thirty-nine patients reported intolerance to any statin (33.9%). The median value of LDL-C before initiation of evolocumab was 147 mg/dL (IQR: 122.5–183.7 mg/dL). Within the first 3 months of treatment, LDL-C value dropped to a median value of 53 mg/dL (IQR: 34.0–95.5 mg/dL), showing a reduction of 63.9%. The median LDL-C values remained below 45 mg/dL until the end of follow-up. Among the patients with available data, up to 61% achieved an LDL-C level below 55 mg/dL at the 10–12-month follow-up. A total of 72% of patients were persistent with treatment. Safety results showed a low frequency of hospitalizations (≤2%) and treatment-emergent adverse drug reactions (5.2%). No serious adverse events were reported.
Conclusions
Evolocumab was associated with reductions in LDL-C levels, with a relative decrease of 63.9% within the first 3 months of treatment. Low rates of interruptions due to adverse events and adequate medication persistence was reported.

“The lower, the better” is the recommended approach in the management of high LDL cholesterol. Unfortunately, this does not always achieve as in the case of a 69-year-old woman referred to our Institute for her lipid profile (LDL cholesterol 412mg/dl), bilateral xanthelasma and cutaneous xanthomas. With a maximized and personalized lipid-lowering therapies (rosuvastatin, ezetimibe, PCSK9i and lipoprotein apheresis), after only six months, the patient showed an impressive regression in her cutaneous xanthomas.
