BACKGROUND
Non-communicable diseases (NCDs) are increasing among people living with HIV (PLHIV), especially in Sub-Saharan Africa (SSA). We determined the prevalence of NCDs and NCD risk factors among PLHIV in SSA to inform health policy makers.
METHODS
We conducted a systematic review and meta-analysis on the prevalence of NCDs and risk factors among PLHIV in SSA. We comprehensively searched PubMed/MEDLINE, Scopus, and EBSCOhost (CINAHL) electronic databases for sources published from 2010 to July 2023. We applied the random effects meta-analysis model to pool the results using STATA. The systematic review protocol was registered on PROSPERO (registration number: CRD42021258769).
FINDINGS
We included 188 studies from 21 countries in this meta-analysis. Our findings indicate pooled prevalence estimates for hypertension (20.1% [95% CI:17.5-22.7]), depression (30.4% [25.3-35.4]), diabetes (5.4% [4.4-6.4]), cervical cancer (1.5% [0.1-2.9]), chronic respiratory diseases (7.1% [4.0-10.3]), overweight/obesity (32.2% [29.7-34.7]), hypercholesterolemia (21.3% [16.6-26.0]), metabolic syndrome (23.9% [19.5-28.7]), alcohol consumption (21.3% [17.9-24.6]), and smoking (6.4% [5.2-7.7]).
INTERPRETATION
People living with HIV have a high prevalence of NCDs and their risk factors including hypertension, depression, overweight/obesity, hypercholesterolemia, metabolic syndrome and alcohol consumption. We recommend strengthening of health systems to allow for improved integration of NCDs and HIV services in public health facilities in SSA. NCD risk factors such as obesity, hypercholesterolemia, and alcohol consumption can be addressed through health promotion campaigns. There is a need for further research on the burden of NCDs among PLHIV in most of SSA.

Meta-Analysis Review
Effects of diets containing fish oils or fish oil concentrates with high cetoleic acid content on the circulating cholesterol concentration in rodents. A systematic review and meta-analysis.
Hypercholesterolaemia is a major risk factor for CVD. Fish intake is associated with lower risk of CVD, whereas supplementation with -3 long-chain PUFA (LC-PUFA) has little effect on the cholesterol concentration. We therefore investigated if cetoleic acid (CA), a long-chain MUFA (LC-MUFA) found especially in pelagic fish species, could lower the circulating total cholesterol (TC) concentration in rodents. A systematic literature search was performed using the databases PubMed, Web of Science and Embase, structured around the population (rodents), intervention (CA-rich fish oils or concentrates), comparator (diets not containing CA) and the primary outcome (circulating TC). Articles were assessed for risk of bias using the SYRCLE's tool. A meta-analysis was conducted in Review Manager v. 5.4.1 (the Cochrane Collaboration) to determine the effectiveness of consuming diets containing CA-rich fish oils or concentrates on the circulating TC concentration. Twelve articles were included in the systematic review and meta-analysis, with data from 288 rodents. Consumption of CA-rich fish oils and concentrates resulted in a significantly lower circulating TC concentration relative to comparator groups (mean difference -0·65 mmol/l, 95 % CI (-0·93, -0·37), < 0·00001), with high statistical heterogeneity ( = 87 %). The risk of bias is unclear since few of the entries in the SYRCLE's tool were addressed. To conclude, intake of CA-rich fish oils and concentrates prevents high cholesterol concentration in rodents and should be further investigated as functional dietary ingredients or supplements to reduce the risk for developing CVD in humans.

Review
BACKGROUND
Researchers have conducted a considerable number of epidemiological studies on dyslipidemia in China over recent years. Nevertheless, a representative study to comprehensively appraise for the epidemiological status of dyslipidemia is still lacked. This meta-analysis is intended to explore the pooled prevalence, rates of awareness, treatment, and control of dyslipidemia among adults in Chinese Mainland.
MATERIALS AND METHODS
A systematic review was performed on relevant cross-sectional studies published since January 2012 by searching six authoritative literature databases. Meta-analyses were conducted in included studies based on a random-effect model to summarize the epidemiological status of dyslipidemia in China. A potential source of heterogeneity was detected by subgroup analysis and meta-regression. Publication bias was assessed by 's test and funnel plots. A sensitivity analysis was conducted to examine the study quality's influence on the pooled estimate of prevalence and rates of awareness, treatment, and control.
RESULTS
Forty-one original researches with a total of 1,310,402 Chinese participants were finally included in the meta-analysis. The prevalence, rates of awareness, treatment, and control of dyslipidemia were 42.1%, 18.2%, 11.6%, and 5.4%, respectively. With a pooled prevalence estimate at 24.5%, low HDL-C was the most prevalent among various dyslipidemia types, followed by hypertriglyceridemia (TG) (15.4%), hypercholesterolemia (TC) (8.3%), and high LDL-C (7.1%). The pooled prevalence of elevated serum lipoprotein(a) [Lp(a)] was 19.4%. By gender, the prevalence of dyslipidemia was 47.3% in males and 38.8% in females. Subgroup analyses revealed that the prevalence in southern and urban areas were higher than their counterparts. Females and population in urban areas tended to possess higher rates of awareness, treatment, and control. Meta-regression analyses suggested that the year of screening influenced prevalence estimates for dyslipidemia. The impact of the study's quality on the pooled estimates is insignificant.
CONCLUSION
Our study suggested a severe epidemic situation of dyslipidemia among adults in Chinese Mainland. More importantly, the awareness, treatment, and control rates were extremely low, revealing that dyslipidemia is a grave health issue. Consequently, we should attach more importance to the management of dyslipidemia, especially in economically underdeveloped areas.

BACKGROUND
We visually assessed the research hotspots of familial hypercholesterolemia (FH) using bibliometrics and knowledge mapping in light of the research state and development trend of FH.
METHODS
We employed bibliometric tools, such as CiteSpace and the alluvial generator, to illustrate the scientific accomplishments on FH by extracting pertinent literature on FH from the Web of Science Core Collection database from January 1, 2002, to December 31, 2022.
RESULTS
A total of 4402 papers in total were selected for study; 29.2% of all articles globally were from the USA, followed by the Netherlands and England. The University of Amsterdam, University of Oslo, and University of Western Australia are the 3 institutions with the most publications in this area. Gerald F. Watts, Raul D. Santos, and John J. P. Kastelein wrote the majority of the pieces that were published. The New England Journal of Medicine, Circulation, and Atherosclerosis were the journals with the greatest number of papers in this field. Prevalence and genetic analysis of FH, proprotein convertase subtilisin/kexin 9 inhibitors, and inclisiran are current research hotspots for the condition. Future research in this area will be focused on gene therapy.
CONCLUSIONS
FH research has shown shows a trend of ascending followed by leveling off. The prevalence and diagnosis of FH, proprotein convertase subtilisin/kexin 9 inhibitors, inclisiran, and gene therapy are current research hotspots. This report may serve as a reference for current research trends.

Meta-Analysis
Dyslipidaemia is an established cardiovascular risk factor. This study aimed to determine the pooled prevalence of dyslipidaemia in Malaysian adults. A systematic review and meta-analysis of all cross-sectional, longitudinal observational studies which reported the prevalence of elevated total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c), triglycerides (TG), and reduced high-density lipoprotein cholesterol (HDL-c) in adults 18 years old and older, was conducted. A comprehensive search of PubMed and Cochrane Central Register of Controlled Trials (which included Medline, EMBASE and major trial registers) from inception to October 18, 2022, was performed. Risk-of-bias was evaluated using the Johanna-Briggs Institute Prevalence Critical Appraisal Tool, while certainty of evidence was assessed using an adapted version of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework. Random-effects meta-analyses were performed using MetaXL. This report follows the PRISMA reporting guidelines. The protocol was registered with PROSPERO (CRD42020200281). 26 556 studies were retrieved and 7 941 were shortlisted initially. From this, 70 Malaysian studies plus two studies from citation searching were shortlisted; 46 were excluded, and 26 were included in the review (n = 50 001). The pooled prevalence of elevated TC (≥ 5.2 mmol/L), elevated LDL-c (≥ 2.6 mmol/L), elevated TG (≥ 1.7 mmol/L), and low HDL-c (< 1.0 mmol/L in men and < 1.3 mmol/L in women) were 52% (95% CI 32-71%, I = 100%), 73% (95% CI 50-92%, I = 100%), 36% (95% CI 32-40%, I = 96%), and 40% (95% CI 25-55%, I = 99%), respectively. This review found that the prevalence of all dyslipidaemia subtypes is high in Malaysian adults. Ongoing efforts to reduce cardiovascular diseases in Malaysia should integrate effective detection and treatment of dyslipidaemia.

Differences in treatment and outcomes among patients with ST-segment elevation myocardial infarction with and without standard modifiable risk factors: a systematic review and meta-analysis.
UNLABELLED
There are limited data available on outcomes and pathophysiology behind ST-segment elevation myocardial infarction (STEMI) in populations without standard modifiable risk factors (SMuRFs). The authors carried out this meta-analysis to understand the differences in treatment and outcomes of STEMI patients with and without SMuRFs.
METHODS
A systematic database search was performed for relevant studies. Studies reporting desired outcomes among STEMI patients with and without SMuRFs were selected based on predefined criteria in the study protocol (PROSPERO: CRD42022341389). Two reviewers independently screened titles and abstracts using Covidence. Full texts of the selected studies were independently reviewed to confirm eligibility. Data were extracted from all eligible studies via a full-text review of the primary article for qualitative and quantitative analysis. In-hospital mortality following the first episode of STEMI was the primary outcome, with major adverse cardiovascular events (MACE), repeat myocardial infarction (MI), cardiogenic shock, heart failure, and stroke as secondary outcomes of interest. Odds ratio (OR) with a 95% CI was used to estimate the effect.
RESULTS
A total of 2135 studies were identified from database search, six studies with 521 150 patients with the first STEMI episode were included in the analysis. The authors found higher in-hospital mortality (OR: 1.43; CI: 1.40-1.47) and cardiogenic shock (OR: 1.59; 95% CI: 1.55-1.63) in the SMuRF-less group with no differences in MACE, recurrent MI, major bleeding, heart failure, and stroke. There were lower prescriptions of statin (OR: 0.62; CI: 0.42-0.91) and Angiotensin converting enzyme inhibitor /Angiotensin II receptor blocker (OR: 0.49; CI: 0.28-0.87) at discharge in SMuRF-less patients. There was no difference in procedures like coronary artery bypass graft, percutaneous coronary intervention, and thrombolysis.
CONCLUSION
In the SMuRF-less STEMI patients, higher in-hospital mortality and treatment discrepancies were noted at discharge.

Impact of alirocumab/evolocumab on lipoprotein (a) concentrations in patients with familial hypercholesterolaemia: a systematic review and meta-analysis of randomized controlled trials.
INTRODUCTION
Familial hypercholesterolaemia (FH) is a common hereditary genetic disorder, characterized by elevated circulating low-density lipoprotein cholesterol (LDL-C) and lipoprotein (a) [Lp(a)] concentrations, leading to atherosclerotic cardiovascular disease (ASCVD). Two types of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors- alirocumab and evolocumab- are efficient drugs in the treatment of FH, which can effectively reduce Lp(a) levels.
MATERIAL AND METHODS
Embase, MEDLINE, and PubMed up to November 2022 were searched for randomized clinical trials (RCTs) evaluating the effect of alirocumab/evolocumab and placebo treatment on plasma Lp(a) levels in FH. Statistics were analysed by Review Manager (RevMan 5.3) and Stata 15.1.
RESULTS
Eleven RCTs involved a total of 2408 participants. Alirocumab/evolocumab showed a significant efficacy in reducing Lp(a) [weighted mean difference (WMD): -20.10%, 95% confidence interval (CI): -25.59% to -14.61%] compared with placebo. In the drug type subgroup analyses, although the efficacy of evolocumab was slightly low (WMD: -19.98%, 95% CI: -25.23% to -14.73%), there was no difference with alirocumab (WMD: -20.54%, 95% CI: -30.07% to -11.02%). In the treatment duration subgroup analyses, the efficacy of the 12-week duration group (WMD: -17.61%, 95% CI: -23.84% to -11.38%) was lower than in the group of ≥ 24 weeks' duration (WMD: -22.81%, 95% CI: -31.56% to -14.07%). In the participants' characteristics subgroup analyses, the results showed that no differential effect of alirocumab/evolocumab therapy on plasma Lp(a) concentrations was observed (heterozygous FH [HeFH] WMD: -20.07%, 95% CI: -26.07% to -14.08%; homozygous FH [HoFH] WMD: -20.04%, 95% CI: -36.31% to -3.77%). Evaluation of all-cause adverse events (AEs) between alirocumab/evolocumab groups and placebo groups [relative risk (RR): 1.05, 95% CI: 0.98-1.12] implied no obvious difference between the 2 groups.
CONCLUSIONS
Anti-PCSK9 drugs (alirocumab and evolocumab) may be effective as therapy for reducing serum Lp(a) levels in FH, and no differences were observed in treatment durations, participant characteristics, and other aspects of the 2 types of PCSk9 inhibitors. However, further experimental studies and RCTs are warranted to clarify the mechanism of PSCK9 inhibitors to lowering Lp(a) concentrations in FH.

Clinical and Experimental Pediatrics Aug 2023The association between dyslipidemia and asthma in children remains unclear.
BACKGROUND
The association between dyslipidemia and asthma in children remains unclear.
PURPOSE
This study investigated the association between dyslipidemia and cholesterol levels in children.
METHODS
A systematic literature review was performed to identify studies investigating the association between dyslipidemia and asthma in children. The PubMed database was searched for articles published from January 2000-March 2022. Data from a cohort study using electronic health records from 5 hospitals, converted to the Observational Medical Outcomes Partnership Common Data Model (OMOP-CDM), were used to identify the association between total cholesterol (TC) levels and asthma in children. This cohort study used the Cox proportional hazards model to examine hazard ratio (HR) of asthma after propensity score matching, and included an aggregate meta-analysis of HR.
RESULTS
We examined 11 studies reporting an association between dyslipidemia and asthma in children. Most were cross-sectional; however, their results were inconsistent. In OMOP-CDM multicenter analysis, the high TC (>170 mg/dL) group included 29,038 children, while the normal TC (≤170 mg/dL) group included 88,823 children including all hospital datasets. In a meta-analysis of this multicenter cohort, a significant association was found between high TC levels and later development of asthma in children <15 years of age (pooled HR, 1.30; 95% confidence interval, 1.12-1.52).
CONCLUSION
Elevated TC levels in children may be associated with asthma.

BACKGROUND
Hypercholesterolemia is a common condition characterized by elevated levels of low-density lipoprotein cholesterol (LDL-C) and increased risk of atherosclerotic cardiovascular disease (ASCVD). Indigenous populations experience disproportionate rates of ASCVD, however, the extent to which hypercholesterolemia contributes to this burden is unknown.
OBJECTIVES
This study aimed to estimate the prevalence of hypercholesterolemia, severe hypercholesterolemia, and familial hypercholesterolemia (FH) in Indigenous populations in Canada, the United States, Australia, and New Zealand.
METHODS
We searched MEDLINE, EMBASE, Web of Science, Native Health Database, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews for peer-reviewed studies reporting on hypercholesterolemia and elevated LDL-C in Indigenous populations. All diagnostic criteria used to classify hypercholesterolemia were included. Pooled prevalence and 95% CIs were calculated using a random-effects model.
RESULTS
There were no studies reporting the prevalence of FH and one study reporting the prevalence of severe hypercholesterolemia in Indigenous populations. The pooled prevalence of hypercholesterolemia was 28.9% or ∼1 in 3 to 1 in 4 individuals (95% CI: 22.4%-36.4%) and 12.6% (95% CI: 7.7%-19.9%) using an LDL-C cutoff of ≥3.5 mmol/L (135 mg/dL). The pooled prevalence in Indigenous populations in North America was 24.3% (95% CI: 17.1%-33.3%) compared with 40.0% (95% CI: 31.3%-49.3%) in Australia. Meta-regression showed diabetes had a significant effect on prevalence ( = 0.022).
CONCLUSIONS
Hypercholesterolemia is prevalent in Indigenous communities and may contribute to the high burden of ASCVD these populations face. There is insufficient research on FH and severe hypercholesterolemia in Indigenous populations worldwide.

BACKGROUND AND OBJECTIVES
Janus kinase (JAK) inhibitors are emerging as a therapeutic option for alopecia areata. The risk of potential adverse events is currently debated. In particular, several safety data for JAK inhibitors are extrapolated from a single study in elderly patients with rheumatoid arthritis treated with tofacitinib or adalimumab/etanercept as a comparator. The population of patients with alopecia areata is clinically and immunologically different from persons with rheumatoid arthritis and tumor necrosis factor (TNF) inhibitors are not effective in these patients. The objective of this systematic review was to analyze available data on the safety of various JAK inhibitors in patients with alopecia areata.
METHODS
The systematic review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A literature review was performed by searching PubMed, Scopus and EBSCO databases with the last search on March 13, 2023.
RESULTS
In total, 36 studies were included. The frequency and odds ratio (OR) for most common adverse events versus placebo were: for baricitinib hypercholesterolemia (18.2% vs 10.5%, OR = 1.9) and headache (6.1% vs 5.1%, OR = 1.2), for brepocitinib elevated creatinine level (27.7% vs 4.3%, OR = 8.6) and acne (10.6% vs 4.3%, OR = 2.7), for ritlecitinib acne (10.4% vs 4.3%, OR = 2.6) and headache (12.5% vs 10.6%, OR = 1.2) and for deuruxolitinib headache (21.4% vs 9.1%, OR = 2.7) and acne (13.6% vs 4.5%, OR = 3.3). The respective numbers for upper respiratory infections were: baricitinib (7.3% vs 7.0%, OR = 1.0) and brepocitinib (23.4% vs 10.6%, OR = 2.6); for nasopharyngitis: ritlecitinib (12.5% vs 12.8%, OR = 1.0) and deuruxolitinib (14.6% vs 2.3%, OR = 7.3).
CONCLUSIONS
The most common side effects of JAK inhibitors in patients with alopecia areata were headache and acne. The OR for upper respiratory tract infections varied from over 7-fold increased to comparable to placebo. The risk of serious adverse events was not increased.
