Objectives: Metabolic syndrome (MetS) is a constellation of coexisting cardiovascular risk factors. This study aimed to assess the evidence for the association between the apolipoprotein B/A1 ratio, apolipoprotein B, and apolipoprotein A1, and the MetS in children and adolescents., Methods: The English electronic databases including PubMed, Embase, Web of Science, and Scopus were searched up to February 28, 2022. To ascertain the validity of eligible studies, modified JBI scale was used. Standardized mean differences (SMDs) with 95% confidence intervals (CIs) were pooled using the random-effects model to evaluate the association between the apolipoprotein B/A1 ratio, apolipoprotein B, and apolipoprotein A1 and the MetS. Heterogeneity amongst the studies was determined by the use of the Galbraith diagram, Cochran's Q-test, and I 2 test. Publication bias was assessed using Egger's and Begg's tests., Results: From 7356 records, 5 studies were included in the meta-analysis, representing a total number of 232 participants with MetS and 1320 participants as control group. The results indicated that increased levels of apolipoprotein B/A1 ratio (SMD 1.26; 95% CI: 1.04, 1.47) and apolipoprotein B (SMD 0.75; 95% CI: 0.36, 1.14) and decreased levels of apolipoprotein A1 (SMD -0.53; 95% CI: -0.69, -0.37) are linked to the presence of MetS. The notable findings were, children and adolescents with MetS had elevated levels of the apolipoprotein B/A1 ratio, apolipoprotein B, and decreased levels of apolipoprotein A1., Conclusions: Our results suggest the need to evaluate the levels of apolipoproteins for detecting the risk of MetS in children and adolescents., Supplementary Information: The online version contains supplementary material available at 10.1007/s40200-023-01235-z., Competing Interests: Conflicts of interest/competing interestsThe authors have no conflicts of interest.

Background: Elderly people have a greater risk than others to develop atherosclerotic disorders. Statins are the most efficient treatments against atherosclerosis; however, the pros and cons of the treatment should be put in balance in regard to the target level of low-density lipoprotein cholesterol (LDL-C). This study evaluates the level of LDL in the Birjand elderly population and determines the achievement of target LDL-C level, according to the American College of Cardiology (ACC) guidelines., Methods: A retrospective observational study of statin therapy was performed from October 2018 using Birjand community health assessment data of the BLAS project. We used the 2018 ACC/AHA guidelines to determine the achievement of target LDL level in statin treated patients with clinical atherosclerotic cardiovascular diseases (ASCVD), or elderly high risk diabetic patients and dyslipidemia ones, in the Birjand elderly dwellers, stratified by statin treatment intensity. Statin and non-statin users were also compared in terms of demographic and laboratory findings. Mann-Whitney U test and Chi-Square test were used for data analysis., Results: Out of 1418 elderly residents in this study, 683 individuals (48.2%) were male with a mean age of 69.73±7.56 years. The total mean level of LDL-C in elderly participants was 122.83±36.21 mg/dL. The mean level of LDL-C in statin use and none statin use group was 104.97±36.01 and 129.09±34.14, respectively. Only 304 (29.2%) of participants who were eligible for statin administration used the statin. While 69 (18.3%) individuals from 378 (26.7%) were using statin though they were not eligible for it. In the clinical ASCVD group, 39 (28.3%) of elderly participants achieved target LDL-C based on the ACC/AHA guideline. This was 58 (37.4%) for other participants with LDL-C ≥190 mg/dL, diabetic or participants with Framingham Risk Score (FRS) ≥10%., Conclusions: The majority of patients who were eligible for high or moderate-intensity statin treatment had not received statin. Only one third of clinical ASCVD patients and almost half of high risk patients achieved LDL-C target values. Findings illustrate current treatment may need to be reconsidered in Birjand elderly dwellers treated with statin and physicians, should be updated on the use of statins., Competing Interests: Conflict of interestThe authors declare that they have no conflict of interest., (© Springer Nature Switzerland AG 2021.)

Background: In 2013, there was an estimation of greater than 4.5 million Afghan refugees who had migrated to the least developed countries. Over one million are legally registered in Iran. We assessed the heart health status as described by the American Heart Association (AHA) in the Afghan refugee populace., Methods: This cross-sectional survey was carried out on 1,634 Afghan refugees, including 746 males (45.7%) and 888 females (54.3%), selected through a convenience sampling method in 2016. The American Heart Association's seven cardiovascular health metrics were evaluated to specify the status of heart health in Afghan refugees. Differences with age and sex were analyzed using the χ 2 test., Results: Only one (0.1%) participant met the ideal for all seven cardiovascular health metrics. No significant differences were found between women and men in meeting the ideal criteria for more than five cardiovascular health metrics. As age increased, the proportion of refugees who met the ideal for more than five cardiovascular health metrics declined., Conclusions: Refugees were not meeting the ideal cardiovascular health for some of the assessed metrics. Intervention to improve and monitor heart health in Afghan refugees is needed., Competing Interests: Conflict of InterestThe authors declare that they have no conflict of interest., (© Springer Nature Switzerland AG 2021.)
