Cardiovascular health metrics are now widely recognized as modifable risk factors for cognitive decline and dementia.Metabolic perturbations might play roles in the linkage of cardiovascular diseases and dementia.Circulating metabolites profling by metabolomics may improve understanding of the potential mechanism by which cardiovascular risk factors contribute to cognitive decline.In a prospective community-based cohort in China(n=725),312 serum metabolic phenotypes were quantifed,and cardiovascular health score was calculated including smoking,exercise,sleep,diet,body mass index,blood pressure,and blood glucose.Cognitive function assessments were conducted in baseline and follow-up visits to identify longitudinal cognitive decline.A better cardiovascular health was signifcantly associated with lower risk of concentration decline and orientation decline(hazard ratio(HR):0.84–0.90;p<0.05).Apolipoprotein-A1,high-density lipoprotein(HDL)cholesterol,cholesterol ester,and phospholipid concentrations were signifcantly associated with a lower risk of longitudinal memory and orientation decline(p<0.05 and adjusted-p<0.20).Mediation analysis suggested that the negative association between health status and the risk of orientation decline was partly mediated by cholesterol ester and total lipids in HDL-2 and-3(proportion of mediation:7.68–8.21%,both p<0.05).Cardiovascular risk factors were associated with greater risks of cognitive decline,which were found to be mediated by circulating lipoproteins,particularly the medium-size HDL components.These fndings underscore the potential of utilizing lipoproteins as targets for early stage dementia screening and intervention.

Background and Aims:Metabolic dysfunction and obe-sity commonly coexist with both alcoholic and nonalcoholic fatty liver disease(AFLD and NAFLD).The association of AFLD and NAFLD with incident diseases in individuals with different metabolic phenotypes are unclear.Methods:UK Biobank study participants were screened for the presence of fatty liver at baseline.Body mass index and metabolic dysfunction were used to define metabolic phenotypes.Cox regression model was performed to examine the associations of AFLD and NAFLD with incident significant liver diseases(SLDs),cardiovascular diseases(CVDs),chronic kidney dis-eases(CKDs),and cancers,respectively.Results:A total of 43,974 AFLD and 103,248 NAFLD cases were identified.Both AFLD and NAFLD were associated with an increased risk of diseases of interest.The effects were amplified by obesity and metabolic abnormalities and modified by metabolic phe-notypes.Compared to individuals free of fatty liver and with phenotype of metabolically healthy-normal weight,AFLD[hazard ratio(HR 3.27;95%CI:1.95-5.47)]and NAFLD(HR 2.25;95%CI:1.28-3.94)cases with phenotype of met-abolically obese-normal weight had the greatest risk of SLDs.For CVDs,CKDs,and cancer,the greatest risks were detected in AFLD and NAFLD cases with phenotype of metabolically obese-overweight/obesity.In this subpopulation,AFLD and NAFLD conferred a 2.75-fold(95%CI:2.32-3.25)and 4.02-fold 95%CI:(3.64-4.43)increased risk of CVDs,4.37-fold 95%CI:(3.38-5.64)and 6.55-fold 95%CI:(5.73-7.48)increased risk of CKDs,and 1.19-fold 95%CI:(1.08-1.27)and 1.21-fold 95%CI:(1.14-1.28)increased risk of cancers,respectively.Conclusions:Metabolic phenotypes modified the association of AFLD and NAFLD with intrahepatic and ex-trahepatic diseases.

Serum liver enzymes(alanine aminotransferase[ALT],aspartate aminotransferase[AST],λ-glutamyl transferase[GGT]and alkaline phosphatase[ALP])are the leading biomarkers to measure liver injury,and they have been reported to be associated with several intrahepatic and extrahepatic diseases in observational studies.We conducted a phenome-wide association study(PheWAS)to identify disease phenotypes associated with genetically predicted liver enzymes based on the UK Biobank cohort.Univariable and multivariable Mendelian randomization(MR)analyses were performed to obtain the causal esti-mates of associations that detected in PheWAS.Our PheWAS identified 40 out of 1,376 pairs(16,17,three and four pairs for ALT,AST,GGT and ALP,respectively)of genotype-phenotype associations reaching statistical significance at the 5%false discovery rate threshold.A total of 34 links were further validated in Mendelian randomization analyses.Most of the disease phenotypes that associated with genetically determined ALT level were liver-related,including primary liver cancer and alcoholic liver damage.The disease outcomes associated with genetically determined AST involved a wide range of phenotypic categories including endocrine/metabolic diseases,digestive diseases,and neurological disorder.Genetically predicted GGT level was associated with the risk of other chronic non-alcoholic liver disease,abnormal results of function study of liver,and cholelithiasis.Genetically determined ALP level was associated with pulmonary heart disease,phlebitis and thrombophlebitis of lower extremities,and hypercholesterolemia.Our findings reveal novel links between liver enzymes and disease phenotypes providing insights into the full understanding of the biological roles of liver enzymes.

Intravenous drug users(IDUs) have been demonstrated to be highly vulnerable to HIV/AIDS.Nevertheless, the prevalence of Kaposi's sarcoma associated herpesvirus(KSHV), an important co-infected agent with HIV, among this population remained obscure. We conducted a systematic review on the epidemiological features of KSHV among IDUs worldwide. Eligible studies were retrieved from 6 electronic databases(Pub Med, EMBASE, Web of Science, CBM, CNKI and Wanfang).We calculated the pooled prevalence and 95% confidence interval(CI) overall and among subgroups using either random-effects model or fixed-effects model depending on between-study heterogeneity. The potential publication bias was assessed by the Egger's test. A meta-regression analysis was performed to explore the sources of heterogeneity. Finally, twenty-two studies with a total sample of 7881 IDUs were included in the analysis. The pooled prevalence of KSHV was14.71%(95% CI 11.12%–19.46%) among IDUs. Specifically, KSHV prevalence was 10.86%(95% CI6.95%–16.96%) in HIV-negative IDUs, and 13.56%(95% CI 10.57%–17.38%) in HIV-positive IDUs.Moreover, prevalence among IDUs from the three continents involved in the current study was similar:16.10%(95%CI 7.73%–33.54%) in Asia; 14.22%(95%CI 8.96%–22.57%) in Europe and 14.06%(95%CI11.38%–17.37%) in America. Globally, IDUs are at higher risk of the KSHV infection when compared with the general population, regardless of geographical region or HIV-infection status.

AIM To study the type and frequency of adverse events associated with anti-tumor necrosis factor(TNF)therapy and evaluate for any serologic and genetic associations.METHODS This study was a retrospective review of patients attending the inflammatory bowel disease(IBD) centers at Cedars-Sinai IBD Center from 2005-2016. Adverse events were identified via chart review. IBD serologies were measured by ELISA. DNA samples were genotyped at Cedars-Sinai using Illumina Infinium Immunochipv1 array per manufacturer's protocol. SNPs underwent methodological review and were evaluated using several SNP statistic parameters to ensure optimal allele-calling. Standard and rigorous QC criteria were applied to the genetic data, which was generated using immunochip. Genetic association was assessed by logistic regression after correcting for population structure.RESULTS Altogether we identified 1258 IBD subjects exposed to anti-TNF agents in whom Immunochip data were available. 269/1258 patients(21%) were found to have adverse events to an anti-TNF-α agent that required the therapy to be discontinued. 25% of women compared to 17% of men experienced an adverse event. All adverse events resolved after discontinuing the antiTNF agent. In total: n = 66(5%) infusion reactions; n = 49(4%) allergic/serum sickness reactions; n = 19(1.5%) lupus-like reactions, n = 52(4%) rash, n = 18(1.4%) infections. In Crohn's disease, Ig A ASCA(P = 0.04) and Ig G-ASCA(P = 0.02) levels were also lower in patients with any adverse events, and anti-I2 level in ulcerative colitis was significantly associated with infusion reactions(P = 0.008). The logistic regression/human annotation and network analyses performed on the Immunochip data implicated the following five signaling pathways: JAK-STAT(Janus Kinase-signal transducer and activator of transcription), measles, IBD, cytokine-cytokine receptor interaction, and toxoplasmosis for any adverse event. CONCLUSION Our study shows 1 in 5 IBD patients experience an adverse event to anti-TNF therapy with novel ser

Traditional triboelectric tactile sensors based on solid–solid interface have illustrated promising application prospects through optimization approach.However,the poor sensitivity and reliability caused by hard contact-electrification still poses challenges for the practical applications.In this work,a liquid–solid interface ferrofluid-based triboelectric tactile sensor(FTTS)with ultrahigh sensitivity is proposed.Relying on the fluidity and magnetism of ferrofluid,the topography of microstructure can be flexibly adjusted by directly employing ferrofluid as triboelectric material and controlling the position of outward magnet.To date,an ultrahigh sensitivity of 21.48 k Pa;for the triboelectric sensors can be achieved due to the high spike microstructure,low Young’s modulus of ferrofluid and efficient solid–liquid interface contact-electrification.The detection limit of FTTS of 1.25 Pa with a wide detection range to 390 k Pa was also obtained.In addition,the oleophobic property between ferrofluid and poly-tetra-fluoro-ethylene triboelectric layer can greatly reduce the wear and tear,resulting in the great improvement of stability.Finally,a strategy for personalized password lock with high security level has been demonstrated,illustrating a great perspective for practical application in smart home,artificial intelligence,Internet of things,etc.

To the Editor:Liver cancer(LC)is one of the most commonly diagnosed cancers and the leading cause of cancer mortality in the world,with approximately 905,677 new cases and 830,180 deaths in 2020.[1]Clearly,the huge burden exerted by LC highlights the need to effectively decrease the incidence and mortality of LC.Unfortunately,survival rates of LC have been maintained at a low level to date.A recent meta-analysis showed that the age-standardized 5-year LC survival rate in China was 10.1%in 2003 to 2005 and 12.1%in 2012 to 2015.[2]The poor prognosis of LC may be partly attributed to the advanced stages once diagnosed for most patients,suggesting that early detection,early diagnosed,and early treatment of LC are warranted.[3]
