BACKGROUND: The American Heart Association recently released a new cardiovascular health (CVH) metric, Life's Essential 8 (LE8), for health promotion. However, the association between LE8 scores and the risk of chronic kidney disease (CKD) remains uncertain. We aimed to explore the association of LE8 scores with new-onset CKD and examine whether socioeconomic deprivation and genetic risk modify this association. METHODS: A total of 286,908 participants from UK Biobank and without prior CKD were included between 2006 and 2010. CVH was categorized using LE8 scores: low (LE8 scores <50), moderate (LE8 scores ≥50 but <80), and high (LE8 scores ≥80). The study outcome was new-onset CKD, ascertained by data linkage with primary care, hospital inpatient, and death data. Cox proportional hazard regression models were used to investigate the association between CVH categories and new-onset CKD. RESULTS: During a median follow-up of 12.5 years, 8857 (3.1%) participants developed new-onset CKD. Compared to the low CVH group, the moderate (adjusted hazards ratio [HR], 0.50; 95% confidence interval [CI]: 0.47-0.53) and high CVH (adjusted HR, 0.31; 95% CI: 0.27-0.34) groups had a significantly lower risk of developing new-onset CKD. The population-attributable risk associated with high vs. intermediate or low CVH scores was 40.3%. Participants who were least deprived ( vs.  most deprived; adjusted HR, 0.75; 95% CI: 0.71-0.79) and with low genetic risk of CKD ( vs.  high genetic risk; adjusted HR, 0.89; 95% CI: 0.85-0.94) had a significantly lower risk of developing new-onset CKD. However, socioeconomic deprivation and genetic risks of CKD did not significantly modify the relationship between LE8 scores and new-onset CKD (both P -interaction >0.05). CONCLUSION Achieving a higher LE8 score was associated with a lower risk of developing new-onset CKD, regardless of socioeconomic deprivation and genetic risks of CKD.

BACKGROUND: Pulmonary arterial hypertension (PAH) presents a significant health burden in Asia and remains a critical challenge. This study aims to delineate the PAH burden in Asia from 1990 to 2021. METHODS: Using the latest data from the Global Burden of Disease 2021, we evaluated and analyzed the distributions and patterns of PAH disease burden among various age groups, sexes, regions, and countries in Asia. Additionally, we examined the associations between PAH disease burden and key health system indicators, including the socio-demographic index (SDI) and the universal health coverage (UHC) index. RESULTS: In 2021, there were 25,989 new PAH cases, 103,382 existing cases, 13,909 PAH-associated deaths, and 385,755 DALYs attributed to PAH in Asia, which accounted for approximately 60% of global PAH cases. The age-standardized rates (ASRs) for prevalence and deaths were 2.05 (95% uncertainty interval [UI]: 1.66-2.52) per 100,000 population and 0.31 (95% UI: 0.23-0.38) per 100,000 population, respectively. From 1990 to 2021, Asia reported the lowest ASRs for PAH prevalence but the highest ASRs for deaths compared to other continents. While the ASRs for prevalence increased slightly, ASRs for mortality and DALYs decreased over time. This increasing burden of PAH was primarily driven by population growth and aging. The burden was especially pronounced among individuals aged ≥60 years and <9 years, who collectively accounted for the majority of deaths and DALYs. Moreover, higher SDI and UHC levels were linked to reduced incidence, but higher prevalence rates. CONCLUSIONS Although progress has been made in reducing PAH-related mortality and DALYs, the disease continues to impose a substantial burden in Asia, particularly among older adults and young children. Region-specific health policies should focus on improving early diagnosis, expanding access to treatment, and effectively addressing the growing PAH burden in the region.

BACKGROUND: The potential impact of pre-existing coronary artery stenosis (CAS) on right ventricular (RV) function during acute pulmonary embolism (PE) episodes remains underexplored. This study aimed to investigate the association between pre-existing CAS and RV dysfunction in patients with acute PE. METHODS: In this multicenter, case-control study, 89 cases and 176 controls matched for age were enrolled at three study centers (Peking Union Medical College Hospital, Fuwai Hospital, and the Second Affiliated Hospital of Harbin Medical University) from January 2016 to December 2020. The cases were patients with acute PE with CAS, and the controls were patients with acute PE without CAS. Coronary artery assessment was performed using coronary computed tomographic angiography. CAS was defined as ≥50% stenosis of the lumen diameter in any coronary vessel >2.0 mm in diameter. Conditional logistic regression analysis was used to evaluate the association between CAS and RV dysfunction. RESULTS: The percentages of RV dysfunction (19.1% [17/89] vs. 44.6% [78/176], P <0.001) and elevated systolic pulmonary artery pressure (sPAP) (19.3% [17/89] vs. 39.5% [68/176], P = 0.001) were significantly lower in the case group than those in the control group. In the multivariable logistic regression model, CAS was independently and negatively associated with RV dysfunction (adjusted odds ratio [OR]: 0.367; 95% confidence interval [CI]: 0.185-0.728; P = 0.004), and elevated sPAP (OR: 0.490; 95% CI: 0.252-0.980; P = 0.035), respectively. CONCLUSIONS Pre-existing CAS was significantly and negatively associated with RV dysfunction and elevated sPAP in patients with acute PE. This finding provides new insights into RV dysfunction in patients with acute PE with pre-existing CAS.

Background::Whether functional gastrointestinal disorders (FGIDs) are associated with the long-term risk of chronic kidney disease (CKD) remains unclear. We aimed to investigate the prospective association of FGIDs with CKD and examine whether mental health mediated the association.Methods::About 416,258 participants without a prior CKD diagnosis enrolled in the UK Biobank between 2006 and 2010 were included. Participants with FGIDs (including irritable bowel syndrome [IBS], dyspepsia, and other functional intestinal disorders [FIDs; mainly composed of constipation]) were the exposure group, and non-FGID participants were the non-exposure group. The primary outcome was incident CKD, ascertained from hospital admission and death registry records. A Cox proportional hazard regression model was used to investigate the association between FGIDs and CKD, and the mediation analysis was performed to investigate the mediation proportions of mental health.Results::At baseline, 33,156 (8.0%) participants were diagnosed with FGIDs, including 21,060 (5.1%), 8262 (2.0%), and 6437 (1.6%) cases of IBS, dyspepsia, and other FIDs, respectively. During a mean follow-up period of 12.1 years, 11,001 (2.6%) participants developed CKD. FGIDs were significantly associated with a higher risk of incident CKD compared to the absence of FGIDs (hazard ratio [HR], 1.36; 95% confidence interval [CI], 1.28–1.44). Similar results were observed for IBS (HR, 1.27; 95% CI, 1.17–1.38), dyspepsia (HR, 1.30; 95% CI, 1.17–1.44), and other FIDs (HR, 1.60; 95% CI, 1.43–1.79). Mediation analyses suggested that the mental health score significantly mediated 9.05% of the association of FGIDs with incident CKD and 5.63–13.97% of the associations of FGID subtypes with CKD. Specifically, the positive associations of FGIDs and FGID subtypes with CKD were more pronounced in participants with a high genetic risk of CKD.Conclusion::Participants with FGIDs had a higher risk of incident CKD, which was partly explained by mental health scores and was more pronounced in those with high genetic susceptibility to CKD.

ObjectiveTo evaluate the methodological and reporting quality of clinical practice guidelines for Chinese patent medicine （CPM） with internationally recognized tools the appraisal of guidelines for research and evaluation （AGEREE） Ⅱ and reporting items for practice guidelines in healthcare （RIGHT）， thereby providing refe-rence for the clinical application and future development of CPM guidelines. MethodsDatabases including CNKI， VIP， Wanfang and Sinomed were searched for CPM guidelines， as well as medlive.cn， websites of China Association of Chinese Medicine and Chinese Medical Association， and reference lists of the included papers. The quality of the guidelines was evaluated using the AGREE Ⅱand RIGHT tools， and consistency tests were performed using Interclass Correlation Coefficient， and descriptive analysis and chi-square test were used to analyze the reporting rate for each domain and the average score for each item. ResultsFinally， 140 CPM guidelines were included， of which 51 were disease-oriented and 89 were drug-oriented， all of which were issued by China. For 51 disease-oriented CPM guidelines， the highest average score of all six AGREE Ⅱ domains was 73.32% for clarity， and the lowest was 26.80% for application； for 89 drug-oriented CPM guidelines， the highest average score was 55.62% for scope and purpose， and the lowest was 31.32% for rigour of development. In terms of the seven domains of the RIGHT checklist， the highest reporting rate was 68.26% for background， and lowest was 27.45% for other areas regarding the disease-oriented CPM guidelines； the highest reporting rate was 61.31% for background， and the lowest was 4.49% for other areas regarding drug-oriented CPM guidelines. The average reporting rate was higher for disease-oriented than drug-oriented CPM guidelines in three domains of AGREE Ⅱ （rigour of development， clarity of presentation， editorial independence）， as well as four domains of RIGHT checklist （basic information， evidence， funding and declaration and management of interests， and other areas）. ConclusionThe overall methodology and reporting quality of the current CPM guidelines still need to be improved. It is recommended that future guideline development teams should strictly refer to the AGREE Ⅱ and RIGHT checklist， and take into account of the characteristics of CPM guidelines and relevant methodo-logical suggestions in the development and reporting of CPM guidelines， thereby guiding the clinical use of CPM in a better way.

Objective To investigate the image quality,radiation dose and contrast medium(CM)intake in coronary computed tomography angiography(CCTA)of overweight patients based on wide-detector using different tube voltages and CM of different concentrations.Methods A total of 150 overweight patients[body mass index(BMI)≥ 25 kg/m2]who underwent CCTA were divided into three groups according to scan protocols:group A(120 kVp,370 mg I/mL CM),group B(100 kVp,350 mg I/mL CM),and group C(80 kVp,320 mg I/mL CM),with each group had 50 patients.The mean CT value,mean signal-to-noise ratio(SNR),mean contrast-to-noise ratio(CNR),figure of merit(FOM)of all images were measured and calculated.Images were assessed using a 5-point scale by two radiologists.The volume CT dose index(CTDIvol)and dose length product(DLP)of each patient were recorded and the effective dose(ED)was calculated.The total iodine intake values of patients in three groups were calculated.The above data were statistically analyzed by one-way ANOVA.Results The mean CT value,mean SNR,mean CNR,and mean subjective score of groups B and C were significantly higher than those of group A(P＜0.001),but there was no significant difference between groups B and C(P＞0.05).The FOM value of groups B and C was significantly higher than that of group A(P＜0.001),and the FOM value of group B was significantly lower than that of group C(P＜0.001).The total iodine intake values of groups B and C was significantly lower than that of group A(P＜0.001).The ED and total iodine intake values in groups B and C were 30.34％,68.53％and 10.22％,16.85％lower than those in group A,respectively(P＜0.001).Conclusion Under the premise of ensuring image quality,the lower tube voltage and lower concentration of CM based on wide-detector allows for significant reduction in radiation dose and total iodine intake in CCTA for overweight patients compared to routine scan protocols.

【Objective】 To explore the composition of culturable bacteria in platelets through bacterial culturomics and verify the results of culturomics and metagenomics to improve the detection rate of bacteria in platelets. 【Methods】 Platelet samples from 6 healthy people were collected. Eight kinds of culture media were placed in aerobic conditions and 12 kinds of culture media were placed in anaerobic conditions for large-scale culture and isolation of bacteria in platelets. The isolated single colony was identified by 16S rRNA gene sequencing. The bacterial abundance of healthy human platelet microbiome was analyzed by metagenomic sequencing, and the cultivable bacterial species in platelets was confirmed based on metagenomic and culturomics results. 【Results】 A total of 90 strains of bacteria belonging to 3 phylums, 5 classes, 5 orders, 7 families, 9 genus and 23 species were isolated from 6 platelet samples by culturomics. Among them, the strains with more monoclonal clones at the species level were Brevundimonas aurantiaca (16.7%), Bacillus sp. Y1 (15.6%), Cutibacterium acnes (14.4%) and Brevibacillus brevis (13.3%). The platelet samples sequenced by mNGS showed that the abundance values of Proteobacteria, Firmicutes and Actinobacteria were high. The bacteria detected by both culturomics and metagenomic sequencing methods were as follows: Firmicutes: Bacillus sp. Y1, B. thuringiensis, B. cereus, B. mobilis, B. velezensis, Staphylococcus epidermidis, and Brevibacillus brevis; Actinobacteria: Cutibacterium acnes; Proteobacteria: Escherichia coli and Delftia tsuruhatensis. 【Conclusion】 The mutual validation of culturomics and metagenomics has identified some bacteria, proving that bacteria exist in platelets.

【Objective】 To explore the influence of common methods of reducing non-viral nucleic acid on the abundance of plasma virus group. 【Methods】 Three kinds of library construction, five kinds of centrifugation conditions, two kinds of filters, four kinds of enzymes and four concentrations of chloroform were used to treat plasma samples added quantitatively 2.16 mL of pseudorabies virus(PRV) and 2.16 mL of porcine parvovirus(PPV). A total of 21.6 mL of plasma samples were processed, including 54 samples. Subsequently, nucleic acid was extracted, mitochondrial DNA(mtDNA) and two viruses were quantitated, the library of the next generation sequencing was constructed, Illumina NovaSeq 6000 was used for the next generation sequencing. The sequencing data were compared with Kraken Py 2.0 software, and the species annotation analysis was conducted. The corresponding species classification information of each segment was obtained to analyze the impact of different reducing non-viral nucleic acid methods on the relative abundance of microorganisms and two indicator viruses. 【Results】 After sequencing by Illumina NovaSeq 6000, 306.27 GB raw data and 193.17 GB clean data were obtained, with Q20>90%, Q30>85%, Error Rate of 0.03%, and average GC Content of 45.02%. The DNA library construction process significantly increased the proportion of microbial sequences and the PRV abundance [(91.8±0.5)%](P<0.05); RNA library construction and combined library construction can increase the abundance of Pestivirus, an RNA virus, and the PRV abundance was(17.7±3.3)% and(8.1±1.5)% respectively. The Ct value of mtDNA was increased and the proportion of human sequence decreased to less than(89.5±1)%, while the proportion of microbial sequence increased to (2.4±0.03)% after treatment of five centrifugation conditions(P<0.05); After centrifugation at 4℃, 100 g, 30 min, the PRV abundance was increased to (40.6±6)%, and centrifugation at 4℃, 4 000 g, 45 min reduced the PRV abundance to (4.1±0.01)%(P<0.05). Both of 0.22-μm filter and 0.45-μm filter increased the Ct value of mtDNA to above 25.56±0.13, decreased the proportion of human sequence to less than (86.1±0.6)%, increased the proportion of microbial sequence to (3.1±0.1)% and (3.4±0.2)%, and decreased the PRV abundance to (1.6±0.3)% and (4.1±0.7)%(P<0.05), while there was no statistical difference in the effect on PPV concentration and abundance. DNase Ⅰ and Benzonase increased the Ct value of PPV to 25.65±0.06 and 25.36±0.45, decreased the proportion of human sequence to (81.7±5.6)% and (72.8±6.7)%, and increased the proportion of microbial sequence and PRV abundance to (11.0±4.1)% and (16.1±4.7)%, (55.8±2.3)% and (39.0±8.9)%, respectively(P<0 05); After treatment with RNase A, the Ct value of PRV increased to 25.20±0.11, and the human sequence proportion decreased to (85.4±5.6)%(P<0 05); Lysozyme had no effect on removing non-viral nucleic acid. The chloroform of 1%, 5%, 10% and 20% increased Ct value of PRV and mtDNA to no less than 27.17±0.21 and 25.68±0.04; Only 10% chloroform increased the proportion of microbial sequences to (3.1±1.2)%(P<0.05); The abundance of PRV with 1% and 5% chloroform treatment was increased to (48.7±13.3)% and (42.1±5.5)%(P<0.05), while 10% and 20% chloroform reduced PRV abundance to (1.0±0.5)% and (3.4±2.8)%(P<0.05). There was no statistical difference in the effect of chloroform with four contents on PPV abundance. 【Conclusion】 Centrifugation at 4℃, 5 000 g, 10 min is suitable for increasing the overall abundance of virus, and centrifugation at 4℃, 100 g, 30 min is suitable for increasing the content of virus similar to PRV. 0.45-μm filter, DNase Ⅰ, Benzonase and low concentration chloroform can effectively reduce the proportion of non-viral nucleic acid sequence in plasma to increase the abundance of the indicated virus group. Thus, the enrichment effect of plasma meta-virome is closely related to the nature of the virus, and the appropriate virus enrichment method should be selected according to the research purpose to establish the corresponding enrichment strategy.

Objective:To systematically evaluate the effect of bariatric and metabolic surgery on bone metabolism in obese patients.Methods:Search terms for the present meta-analysis included "bariatric surgery, metabolic surgery, sleeve gastrectomy, gastric bypass, bone metabolic indicators, bone mineral density", both in English and corresponding Chinese. PubMed, WOS, Cochrane, CNKI, and VIP databases were searched for longitudinal studies from the establishment of the database to September 20, 2022. The data on bone mineral density and bone metabolic markers in obese patients before and after bariatric surgery were extracted. RevMan5.4 and Stata17.0 software were used for Meta-analysis.Results:A total of 8 clinical studies with 420 patients were included. The results of the meta-analysis showed that compared with the preoperative baseline, lumbar spine bone mineral density ( WMD=0.05, 95% CI: -0.00~0.1), femoral neck bone mineral density( WMD=0.10, 95% CI: 0.05-0.15), hip bone mineral density( WMD=0.14, 95% CI: 0.10-0.17), and serum vitamin D 3 ( WMD=-4.87, 95% CI: -6.34--3.40)were decreased, while parathyroid hormone ( WMD=10.04, 95% CI: 5.32-14.76) was elevated after surgery. Conclusions:Current evidence demonstrates that metabolic and bariatric surgery can lead to decreased bone mineral density and impairs in bone metabolic markers early after surgery. Roux-en-Y gastric bypass surgery cause more adverse effects on bone metabolism than sleeve gastrectomy. The results imply that all patients undergoing metabolic and bariatric surgery should be monitored for bone metabolism and routinely take vitamin D and calcium supplements.

Objective:To analyze the incidence of gallstone formation after Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) by meta-analysis.Methods:English terms for this meta-analysis included "bariatric surgery, gastric bypass, Roux-n-Y gastric bypass, RYGB, sleeve gastrectomy, SG, cholelithiasis, cholecystectomy, gallstone". Researched articles in Pubmed, Medline and Embase databases were searched up to February 2023 and retrieved for further analysis. The quality of each article was evaluated with Newcastle-Ottawa Scale (NOS). Generated data were analyzed with Revman 5.4.Results:Nine relevant cohort studies were retrieved for this meta-analysis, including a total of 24 255 RYGB patients and 4 500 SG patients. All articles met the requirements after the quality evaluation of NOS. The meta-analysis results showed that the incidence of postoperative gallstones in RYGB group was higher than that in SG group ( P<0.001). In subgroup analysis, by administering ursodeoxycholic acid (UDCA) for gallstone prevention, the incidence had no difference between the two groups ( P=0.090), while in the study without UDCA, the incidence of gallstones after RYGB was higher than SG ( P=0.005). In the studies with follow-up time no more than 24 months, the incidence of postoperative gallstones in RYGB group was higher than that in SG group ( P=0.050), but there was no statistical difference when following-up beyond 24 months ( P=0.240). Conclusions:Within 2 years after surgery, RYGB patients have more chances to develop gallstones than SG patients. However, beyond 2-year follow-up, there is no difference between the two procedures. Prophylactical utilization of UDCA after RYGB can effectively reduce the incidence of gallstone formation.
