Alcohol consumption and accelerated biological ageing in middle-aged and older people: A longitudinal study from two cohorts.

BACKGROUND AND AIMS: The relationship between alcohol consumption and age-related diseases is inconsistent. Biological age (BA) serves as both a precursor and a predictor of age-related diseases; however, longitudinal associations between alcohol consumption and BA in middle-aged and older people remain unclear. We measured whether there was a longitudinal association between drinking frequency and pure alcohol intake with BA among middle-aged and older people. DESIGN AND SETTING AND PARTICIPANTS: This study involved two prospective cohort studies, set in Southwestern China and the United Kingdom. A total of 8046 participants from the China Multi-Ethnic Cohort study (CMEC) and 5412 participants from the UK Biobank (UKB), aged 30-79 years, took part, with complete data from two waves of clinical biomarkers. MEASUREMENTS: BA was calculated by the Klemera Doubal's method. Accelerated BA equalled BA minus chronological age. Drinking frequency and pure alcohol intake were obtained through self-reported questionnaires. Drinking frequency in the past year was classified as current non-drinking, occasional (monthly drinking) and regular (weekly drinking). FINDINGS: Compared with consistent current non-drinkers, more frequent drinkers [CMEC: ß = 0.46, 95% confidence interval (CI) = 0.13-0.80; UKB: ß = 0.65, 95% CI = 0.01-1.29)], less frequent drinkers (CMEC: ß = 0.62, 95% CI = 0.37-0.87; UKB: ß = 0.54, 95% CI = -0.01-1.09), consistent occasional drinkers (CMEC: ß = 0.51, 95% CI = 0.23-0.79; UKB: ß = 0.63, 95% CI = 0.13-1.13) and consistent regular drinkers (CMEC: ß = 0.56, 95% CI = 0.17-0.95; UKB: ß = 0.46, 95% CI = 0.00-0.91) exhibited increased accelerated BA. A non-linear relationship between pure alcohol intake and accelerated BA was observed among consistent regular drinkers. CONCLUSIONS: In middle-aged and older people, any change in drinking frequency and any amount of pure alcohol intake seem to be positively associated with acceleration of biological ageing, compared with maintaining abstinence.

The Role of Different Systemic Inflammatory Indexes Derived from Complete Blood Count in Differentiating Acute from Chronic Calculus Cholecystitis and Predicting Its Severity.

Purpose: This study aimed to evaluate the diagnostic value of the different Complete blood count-derived systemic inflammation indexes, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), and neutrophil to lymphocyte × platelet ratio (NLPR) in differential diagnosing the chronic calculus cholecystitis (CCC) and the acute calculus cholecystitis (ACC), as well as determining the severity of ACC. Patients and Methods: 105 CCC and 88 ACC patients were enrolled. NLR, PLR, SII, and NLPR were evaluated in both cohorts as well as in different severity levels of ACC. The severity of ACC was determined based on the Tokyo Guidelines. Receiver operating characteristic (ROC) curve and Univariate/multivariate regression analyses were conducted. Results: The levels of NLR, PLR, SII, and NLPR were significantly higher in the ACC group compared to the CCC group. The optimal cutoff values for NLR, PLR, SII, and NLPR were determined to be 3.89, 144.7, 896.8, and 0.031 respectively. NLR>3.89 demonstrates the highest predictive capability with an AUC of 0.801 and a sensitivity of 72.73%. Multivariate analysis showed that NLR>3.89 (OR: 4.169, p = 0.004) and NLPR>0.031 (OR: 4.304, p = 0.005) were dominant in distinguishing ACC from CCC. In ACC patients, the levels of NLR, SII, and NLPR were significantly higher in the Moderate to Severe-degree ACC (MS-ACC) group than in Mild-Degree ACC (M-ACC). NLPR > 0.044 exhibited the highest predictive ability with an AUC of 0.778 and a specificity of 91.67%. Multivariate analysis showed that NLR>6.399 (OR: 10.308, p = 0.000) was a possible independent prognostic factor for accessing the severity of ACC. Conclusion: Systemic inflammation indexes can be useful in predicting the risk of ACC and MS-ACC. NLR demonstrates the best distinguishing power and sensitivity for distinguishing ACC from CCC, while NLPR shows the best predictive power and specificity for predicting the severity of ACC.

Long-term exposure to fine particulate matter constituents in relation to chronic kidney disease: evidence from a large population-based study in China.

The effects of long-term exposure to fine particulate matter (PM2.5) constituents on chronic kidney disease (CKD) are not fully known. This study sought to examine the association between long-term exposure to major PM2.5 constituents and CKD and look for potential constituents contributing substantially to CKD. This study included 81,137 adults from the 2018 to 2019 baseline survey of China Multi-Ethnic Cohort. CKD was defined by the estimated glomerular filtration rate. Exposure concentration data of 7 major PM2.5 constituents were assessed by satellite remote sensing. Logistic regression models were used to estimate the effect of each PM2.5 constituent exposure on CKD. The weighted quantile sum regression was used to estimate the effect of mixed exposure to all constituents. PM2.5 constituents had positive correlations with CKD (per standard deviation increase), with ORs (95% CIs) of 1.20 (1.02-1.41) for black carbon, 1.27 (1.07-1.51) for ammonium, 1.29 (1.08-1.55) for nitrate, 1.20 (1.01-1.43) for organic matter, 1.25 (1.06-1.46) for sulfate, 1.30 (1.11-1.54) for soil particles, and 1.63 (1.39-1.91) for sea salt. Mixed exposure to all constituents was positively associated with CKD (1.68, 1.32-2.11). Sea salt was the constituent with the largest weight (0.36), which suggested its importance in the PM2.5-CKD association, followed by nitrate (0.32), organic matter (0.18), soil particles (0.10), ammonium (0.03), BC (0.01). Sulfate had the least weight (< 0.01). Long-term exposure to PM2.5 sea salt and nitrate may contribute more than other constituents in increasing CKD risk, providing new evidence and insights for PM2.5-CKD mechanism research and air pollution control strategy.

Life's Essential 8, Life's Simple 7 and the odds of hyperuricaemia: results from the China Multi-Ethnic Cohort Study.

Objective: Life's Essential 8 (LE8) is a new comprehensive metric based on Life's Simple 7 (LS7). Few studies have investigated the association between LE8 and the odds of hyperuricaemia (HUA). This study examined the association between LE8, LS7 with odds of HUA. Methods: We cross-sectionally analysed data from the China Multi-Ethnic Cohort (CMEC) study. LE8 and LS7 were categorized as low, moderate and high. The CMEC provided an ideal and unique opportunity to characterize the association between LE8, LS7 and the odds of HUA. Results: Of the 89 823 participants, 14 562 (16.2%) had HUA. A high level of LE8 was associated with lower odds of HUA after full adjustment. The adjusted odds ratios (ORs) were 1 (reference), 0.70 (95% CI 0.67, 0.73) and 0.45 (0.42, 0.48) across low, moderate and high LE8 groups, respectively (Ptrend < 0.001). Similar results were observed in LS7 and HUA. The adjusted ORs were 1 (reference), 0.68 (95% CI 0.65, 0.71) and 0.46 (95% CI 0.43, 0.49) across low, moderate and high LS7 groups, respectively (Ptrend < 0.001). There were significant interactions between LE8 and age, gender, ethnicity and drinking habits on HUA. Receiver operating characteristics analysis showed that the area under the curve for LE8 and LS7 were similar (0.638 and 0.635, respectively). Conclusion: This study indicated a clearly inverse gradient association between the cardiovascular health metrics LE8 and LS7 and the odds of HUA.

Effect of vegetable consumption on risk of gastric cancer: a systematic review and multi-level meta-analysis of prospective studies.

Vegetables are known to be beneficial to human health, but the association between vegetable consumption and gastric cancer remains uncertain. To synthesise knowledge about the relationship between vegetable group consumption and gastric cancer risk, update present meta-analyses and estimate associations between vegetable consumption and gastric cancer risk based solely on prospective studies, we perform a PRISMA-compliant three-level meta-analysis. Systematic search identified thirteen prospective studies with fifty-two effect sizes that met all inclusion criteria and no exclusion criteria for our meta-analysis. Pooled risk ratios (RRs) showed a positive association between high vegetable consumption and low gastric cancer risk (pooled RR 0·93, 95% confidence interval 0·90-0·97, P = 0·06). In moderator analyses for indicators of gender, region and quantity of vegetable intake, there was no significant difference between subgroups. However, the effect became significant in populations with lower than the minimum risk exposure level (TMREL) of vegetable consumption (P < 0·05). Higher vegetable intake is associated with a decreased risk of gastric cancer. This effect may be limited to specific populations, such as ones with lower vegetable consumption. Evidence from our study has important public health implications for dietary recommendations.

The Epidemic Characteristics of Stroke Death from 2012 to 2021 in Chongqing, China.

INTRODUCTION: Stroke has become a major disease that threatens the global population's health and is a major public health problem that needs to be solved in China. Therefore, it is essential to analyze the trend of the mortality of stroke and its epidemic characteristic of stroke death. METHODS: Death cases of stroke were reported to the national death registry system by the medical staff of all medical institutions, and the population data every year were obtained from District or County's Statistic Bureau in Chongqing. They were analyzed to calculate the mortality, age-standardized mortality rate by Chinese standardization population (ASMRC), age-specific mortality, proportion, and annual percent of change (APC) according to the ICD-10 code. ASMRC was based on the standard population of the 6th census in China, 2010. The stroke mortality of each subgroup was compared using the χ2 test. Trend analysis was presented by APC. RESULTS: The crude mortality of stroke increased from 96.29 per 100,000 in 2012 to 115.93 per 100,000 significantly, with the APC of 2.02% (t = 2.82, p = 0.022) in Chongqing. ASMRC of stroke was 56.47 per 100,000 in 2012 and 54.70 per 100,000 in 2021, and its trend change was stable (APC = -0.01, t = 0.07, p = 0.947). The crude mortality of stroke in males was higher than that in females every year (p < 0.05). The death proportion of intracerebral hemorrhage dwindled from 60.53% in 2012 to 49.88% in 2021, whereas the death proportion of ischemic stroke increased from 20.92% in 2012 to 39.96% in 2021. The average age of stroke death was delayed from 73.43 years old in 2012 to 76.52 years old in 2021 significantly (t = 18.12, p < 0.001). The percentage of stroke death at home increased from 75.23% in 2012 to 79.23% in 2021, while the percentage of stroke death at hospitals decreased from 17.89% in 2012 to 15.89% in 2021. CONCLUSION: The crude mortality of stroke surged, and intracerebral hemorrhage was the main death cause of all subtypes. The mortality of stroke in males and rural residents was higher than that in females and urban residents. Most stroke deaths occurred at home. Male and rural residents were crucial populations for stroke prevention and control. There should be improved medical resources in rural areas and enhanced capability of stroke diagnosis and treatment.

Cost-effectiveness analysis of hepatitis E vaccination strategies among patients with chronic hepatitis B in China.

AIM: This study aimed to evaluate the cost-effectiveness of hepatitis E vaccination strategies in chronic hepatitis B (CHB) patients. METHODS: Based on the societal perspective, the cost-effectiveness of three hepatitis E vaccination strategies-vaccination without screening, screening-based vaccination, and no vaccination-among CHB patients was evaluated using a decision tree-Markov model, and incremental cost-effectiveness ratios (ICERs) were calculated. Values for treatment costs and health utilities were estimated from a prior investigation on disease burden, and values for transition probabilities and vaccination-related costs were obtained from previous studies and government agencies. Sensitivity analyses were undertaken for assessing model uncertainties. RESULTS: It was estimated that CHB patients superinfected with hepatitis E virus (HEV) incurred significantly longer disease course, higher economic burden, and more health loss compared to those with HEV infection alone (all p < 0.05). The ICERs of vaccination without screening and screening-based vaccination compared to no vaccination were 41,843.01 yuan/quality-adjusted life year (QALY) and 29,147.32 yuan/QALY, respectively, both lower than China's per-capita gross domestic product (GDP) in 2018. The screening-based vaccination reduced the cost and gained more QALYs than vaccination without screening. One-way sensitivity analyses revealed that vaccine price, vaccine protection rate, and decay rate of vaccine protection had the greatest impact on the cost-effectiveness analysis. Probabilistic sensitivity analyses confirmed the base-case results, and if the willingness-to-pay value reached per-capita GDP, the probability that screening-based vaccination would be cost-effective was approaching 100%. CONCLUSIONS: The disease burden in CHB patients superinfected with HEV is relatively heavy in China, and the screening-based hepatitis E vaccination strategy for CHB patients is the most cost-effective option.

CD30 plays a role in T-dependent immune response and T cell proliferation.

CD30 is a member of the tumor necrosis factor receptor (TNFR) superfamily and expressed in both normal and malignant lymphoid cells. However, the role of CD30 in lymphopoiesis is not known. In this study, we showed CD30 was expressed both in T and B cells, but its deficiency in mice had no effect on T- and B-cell development. In fact, CD30 deficiency attenuated B-cell response to T-cell-dependent antigens. The impaired B cell response in CD30-deficient mice is caused by the reduction of activation-induced cytidine deaminase (AID) expression. Moreover, CD30-deficient mice exhibited decreased TCR-mediated T cell proliferation and slightly impaired TCR signaling. High-throughput RNA sequencing analysis revealed that CD30 deficiency led to a decrease of FOXO-autophagy axis in T cells upon TCR stimulation. Thus, CD30 positively regulates T-cell-dependent immune response and T cell proliferation.

Age-Related Effect of Uric Acid on Contrast-Induced Acute Kidney Injury of Patients Undergoing Coronary Angiography.

Background: The association between uric acid (UA) and contrast-induced acute kidney injury (CI-AKI) following coronary angiography (CAG) has been established. However, whether the association would vary with age remained undetermined. Methods: We performed the retrospective analysis based on the Cardio-renal Improvement II study, (ClinicalTrials.gov NCT05050877), which enrolled consecutive patients undergoing coronary angiography in 5 teaching hospitals in China from 2007 to 2020. The primary outcome was CI-AKI defined as the rise of serum creatinine (SCr) ≥ 0.5 mg/dL or 25% compared with the baseline value within 48 hours following CAG. The effect of age on the association between uric acid and CI-AKI was assessed by the logistic regression model. Results: A total of 36,550 patients (mean age 63.08±5.6-year-old, 41.7% men) were included in the study. After adjusting for the confounders, the risk of CI-AKI between each quartile of uric acid was insignificant in the young group. In patients of the middle group, lower UA was associated with a lower risk of CI-AKI while higher UA was associated with a higher risk (Q1 OR: 0.853, 95% CI: 0.734-0.993; Q4 OR: 1.797, 95% CI: 1.547-2.09). In patients of the elder group, lower and higher UA were both associated with a higher risk of CI-AKI (Q1 OR: 1.247, 95% CI: 1.003-1.553; Q4 OR: 1.688, 95% CI: 1.344-2.124). The restricted cubic spline indicated a non-linear association between UA and CI-AKI in middle and elder age groups but a linear association in the young age group. Conclusion: The association between uric acid and CI-AKI vary in patients of different age. Patients with elder age should maintain a middle level of uric acid while patients with middle age should consider a lower level of uric acid to reduce the risk of CI-AKI. The level of UA was an insignificant risk factor for CI-AKI in young patients.

Association of triglyceride-glucose index with the prevalence of cardiovascular disease in malnourished/non-malnourished patients: a large cross-sectional study.

Background: Numerous investigations have demonstrated a strong association between the TyG (triglyceride-glucose) index, which is derived from lipid and glucose levels in the bloodstream, and the onset and progression of cardiovascular diseases (CVD). Blood glucose and blood lipids are affected by nutritional status, and few studies have explored whether the correlation between TyG index and the risk of CVD is affected by nutritional status. Aims: To investigate the connection between TyG index and the risk of CVD among individuals with varying nutritional statuses. Method: A total of 19,847 were included in the analysis, of which 15,955 participants were non-malnourished and 3,892 patients were malnourished. According to the TyG index quartile, the patients were categorized into four groups. Logistic regression analysis and restricted cubic spline was used to study the relationship between TyG index and the risk of CVD in normal and malnourished populations. Results: The results of the restricted cubic spline showed that the TyG index was positively associated with the risk of CVD in the non-malnourished population. The TyG index showed a U-shaped association with the risk of CVD in malnourished people. The result is consistent with that of logistic regression (Malnutrition: Group 2: OR: 1.14; 95% CI: 0.85-1.53; Group 3: OR: 1.36; 95% CI: 1.03-1.79; Group 4: OR: 1.72; 95% CI:1.31-2.25, P for trend <0.001; Non-malnutrition: Group 2: OR: 0.82; 95% CI: 0.46-1.48; Group 3: OR: 0.88; 95% CI: 0.49-1.57; Group 4: OR: 1.45; 95% CI:0.83-2.52, P for trend =0.067). Conclusions: The association between the TyG index and the risk of CVD varied depending on the nutritional states. When using TyG index to assess the risk of CVD, stratification combined with nutritional status helps to more accurately screen patients at high risk of CVD.

Ginsenoside Rg1 Alleviates Ulcerative Colitis in Obese Mice by Regulating the Gut Microbiota-Lipid Metabolism-Th1/Th2/Th17 Cells Axis.

Ginsenoside Rg1 (G-Rg1) has various pharmacological properties including antiobesity, immunomodulatory, and anti-inflammatory effects. This study aimed to explore the therapeutic effects and underlying mechanisms of G-Rg1 on colitis complicated by obesity. The results indicate that G-Rg1 effectively alleviates colitis in obese mice and improves serum lipid levels and liver function. Importantly, G-Rg1 improved the composition of gut microbiota in obese mice with colitis, with increases in alpha diversity indexes Sobs, Ace, and Chao, a significant down-regulation of the relative abundance of Romboutsia, and a significant up-regulation of Rikenellaceae_RC9_gut_group, Lachnospiraceae_NK4A136_group, Enterorhabdus, Desulfovibrio, and Alistipes. Meanwhile, G-Rg1 improved lipid metabolism in the colonic contents of obese mice with colitis. Additionally, G-Rg1 significantly reduced the percentages of helper T (Th)1, Th17, central memory T (TCM), and effector memory T (TEM) cells in obese mice with colitis while significantly increasing Naïve T and Th2 cells. In conclusion, G-Rg1 could be a promising therapeutic option for alleviating obesity complicated by colitis through regulation of the gut microbiota and lipid metabolism as well as Th1/Th2/Th17 cell differentiation.

Dietary patterns and metabolic dysfunction-associated fatty liver disease in China's multi-ethnic regions.

BACKGROUND: The prevalence of metabolic dysfunction-associated fatty liver disease (MAFLD) has been rising rapidly in western China. Diet acts as an effective therapy for MAFLD. However, there has been scarce research on the association between a posteriori diet patterns (DPs) and MAFLD in this region. METHOD: We identified three a posteriori DPs which were "Sichuan Basin pattern" characterized by a high intake of fish/seafood, poultry, fresh fruit and vegetables, indicating a balanced and modern DP; the "Yunnan-Guizhou Plateau dietary pattern" characterized mainly by a high intake of animal oil and salt, indicating an agricultural and poor DP; and the "Qinghai-Tibet Plateau dietary pattern" characterized by a high intake of coarse grains, wheat products, tubers and tea, respectively, indicating a high-altitude DP. Then, we performed marginal structural models that combined logistic regression and inverse probability exposure weighting (IPEW) to examine the associations between MAFLD and these a posteriori DPs. RESULT: We found the "Yunnan-Guizhou Plateau dietary pattern" revealed stronger positive association (OR = 1.50, 95% CI 1.40-1.60) with MAFLD than that of the "Qinghai-Tibet Plateau dietary pattern" (OR = 1.21, 95% CI 1.14-1.30). In contrast, the "Sichuan Basin dietary pattern" showed no significant association with MAFLD. In the further stratified analysis, we found those above associations were stronger in ethnic minorities and rural residents than their counterparts. CONCLUSION: Our study implied the unfavourable effects of "Yunnan-Guizhou Plateau dietary pattern" on MAFLD and provided evidence that reducing the intake of oil and sodium may be optimal for MAFLD control in the multi-ethnic region in western China.

Th1/Th2 cytokine profile in patients with acute and chronic calculus cholecystitis.

Relatively little is known about the relationship between Th1/Th2 cytokines and calculus cholecystitis (CC). The purpose of this study was to investigate the correlation between serum Th1 and Th2 cytokine expression and CC, including both acute and chronic cases. In total, 102 patients with chronic calculous cholecystitis (CCC), 64 patients with acute calculous cholecystitis (ACC), and 55 healthy controls (HCs) were recruited for the study. Serum concentration of Th1 (IL-2, TNF-α, IFN-γ) and Th2 cytokines (IL-4, IL-6, IL-10) was measured at admission and on the fifth day after cholecystectomy using flow cytometry. In addition, the ratio of IL-6/IL-10 was calculated. Correlation of the corresponding factors was then analysed, and univariate and multivariate Cox regression analyses were performed to identify independent markers of ACC severity. Compared to HCs, CCC patients exhibited significantly elevated expression levels of IL-6 and IL-10, while ACC patients demonstrated higher expression of IL-2, TNF-α, and IL-6/ IL-10 in addition to IL-6, and IL-10. In ACC patients, there was a strong positive correlation between IL-6 and IL-10 concentration, the expression of IL-2 was observed to positively correlate with serum ALT and AST concentration, and TNF-α expression positively correlated with the duration of hospitalization. Moreover, patients with moderate-to-severe ACC presented with higher expression of IL-10 compared to those with mild ACC. Cox regression analysis confirmed that IL-10 and IL-6 were independent factors for the severity of ACC. Following surgery, the levels of IL-6 and IL-6/IL-10 significantly decreased but did not fully return to baseline levels in ACC patients. Our study reveals atypical Th1/Th2 cytokine expression profiles in patients with acute and chronic CC, and further highlights the significant potential of these cytokines, particularly IL-6 and IL-10, in assessing the severity and progression of CC.

Association between alcohol consumption and risk of hyperuricaemia among adults: a large cross-sectional study in Chongqing, China.

OBJECTIVE: To investigate the relationship between alcohol consumption and hyperuricaemia (HUA), we conducted a study based on a large population. SETTING: Cross-sectional study. PARTICIPANTS: A total of 20 833 participants aged 30-79 years were enrolled in the China Multi-Ethnic Cohort, Chongqing region. OUTCOMES: The serum level of uric acid, fasting blood glucose and blood lipids were tested. Basic demographic statistics such as age, gender, marital status, education level, family annual income and the detail information of alcohol consumption were collected using a standardised questionnaire. RESULTS: After controlling for potential confounders, compared with participants who never consumed alcohol, participants who drank 3-5 days per week had the highest risk of HUA (OR: 1.51, 95% CI: 1.25 to 1.82) and those who drank alcohol harmfully had the highest risk of HUA (OR: 1.81, 95% CI: 1.41 to 2.32). In addition, we found that those who drank moderately had no significant association with risk of HUA. However, among men, compared with participants who never consumed alcohol, those who drank moderately was also a risk factor of HUA (OR: 1.23, 95% CI: 1.03 to 1.46) and those who drank alcohol harmfully had the highest risk of HUA (OR: 2.13, 95% CI: 1.64 to 2.78). Compared with participants who drank alcohol moderately, the OR (95% CI) for those who drank alcohol harmfully had the highest risk of HUA was 1.88 (1.42 to 2.48), and the corresponding OR (95% CI) for each level increment in the degree of alcohol consumption was 1.22 (1.12 to 1.33). Among men, compared with participants who drank alcohol moderately, those who drank alcohol harmfully had the highest risk of HUA (OR: 1.93, 95% CI: 1.45 to 2.57), as well as the corresponding OR (95% CI) for each level increment in the degree of alcohol consumption was 1.24 (1.13 to 1.35). CONCLUSION: This study suggested that the frequency and degree of alcohol consumption may be the risk factors for HUA, especially in males.

Proportion and number of incident cancer deaths in coronary artery disease.

BACKGROUND: Globally, coronary artery disease (CAD) and cancer are the leading causes of death. Studies focusing on the proportion and spectrum of cancer mortality among CAD patients are lacking. We aim to characterize the proportion and spectrum of cancer-specific mortality among patients with CAD. METHODS: We analyzed 93,797 hospitalized survivors with angiographically documented CAD between 2007 and 2020 (mean age: 62.8 ± 11.1 years, 24.7% female) from Cardiorenal ImprovemeNt II (CIN-II) cohort. RESULTS: During the median follow-up of 4.8 years (IQR: 2.6-7.5), 13,162 (14.0%) patients died after discharge. A total of 1223/7703 (15.8% of cause-specific death) CAD patients died of cancer. The three most common types of cancer-specific death were lung (36.1%), liver (13.3%), and colorectum cancer (12.8%). Furthermore, male (adjusted HR 2.38, 95% CI: 1.99-2.85) and older (≥60 vs. <60 years, adjusted HR 3.25, 95%CI 2.72-3.88) patients had a significantly increased cancer-specific mortality. CONCLUSIONS: Our data suggest that nearly one-sixth of death is accounted for cancer among CAD patients within a median follow-up of 4.8 years. Lung, liver, and colorectum cancer are top three cancer-specific mortality. Further studies are needed to reduce cancer mortality for CAD patients, especially in older and male ones. TRAIL REGISTRATION: (ClinicalTrials.gov NCT05050877).

Identification and quantitative assessment of motor complications in Parkinson's disease using the Parkinson's KinetiGraph™.

Introduction: Effective management and therapies for the motor complications of Parkinson's disease (PD) require appropriate clinical evaluation. The Parkinson's KinetiGraph™ (PKG) is a wearable biosensor system that can record the motion characteristics of PD objectively and remotely. Objective: The study aims to investigate the value of PKG in identifying and quantitatively assessing motor complications including motor fluctuations and dyskinesia in the Chinese PD population, as well as the correlation with the clinical scale assessments. Methods: Eighty-four subjects with PD were recruited and continuously wore the PKG for 7 days. Reports with 7-day output data were provided by the manufacturer, including the fluctuation scores (FS) and dyskinesia scores (DKS). Specialists in movement disorders used the Movement Disorder Society-Unified Parkinson's Disease Rating Scale-IV (MDS-UPDRS IV), the wearing-off questionnaire 9 (WOQ-9), and the unified dyskinesia rating scale (UDysRS) for the clinical assessment of motor complications. Spearman correlation analyses were used to evaluate the correlation between the FS and DKS recorded by the PKG and the clinical scale assessment results. Receiver operating characteristic (ROC) curves were generated to analyze the sensitivity and specificity of the FS and DKS scores in the identification of PD motor complications. Results: The FS was significantly positively correlated with the MDS-UPDRS IV motor fluctuation (items 4.3-4.5) scores (r = 0.645, p < 0.001). ROC curve analysis showed a maximum FS cut-off value of 7.5 to identify motor fluctuation, with a sensitivity of 74.3% and specificity of 87.8%. The DKS was significantly positively correlated with the UDysRS total score (r = 0.629, p < 0.001) and the UDysRS III score (r = 0.634, p < 0.001). ROC curve analysis showed that the maximum DKS cut-off value for the diagnosis of dyskinesia was 0.7, with a sensitivity of 83.3% and a specificity of 83.3%. Conclusion: The PKG assessment of motor complications in the PD population analyzed in this study has a significant correlation with the clinical scale assessment, high sensitivity, and high specificity. Compared with clinical evaluations, PKG can objectively, quantitatively, and remotely identify and assess motor complications in PD, providing a good objective recording for managing motor complications.

Elevated urine albumin creatinine ratio increases cardiovascular mortality in coronary artery disease patients with or without type 2 diabetes mellitus: a multicenter retrospective study.

BACKGROUND: Albuminuria has been suggested as an atherosclerotic risk factor among the general population. However, whether this association will be amplified in patients with coronary artery disease (CAD) is unknown. It is also unknown whether diabetes mellitus confounds the association. We aim to analyse the prognosis of elevated urine albumin creatinine ratio (uACR) in the CAD population with or without type 2 diabetes mellitus (T2DM). METHODS: This multi-center registry cohort study included 5,960 patients with CAD. Patients were divided into T2DM and non-T2DM group, and baseline uACR levels were assessed on three grades (low: uACR < 10 mg/g, middle: 10 mg/g ≤ uACR < 30 mg/g, and high: uACR ≥ 30 mg/g). The study endpoints were cardiovascular mortality and all-cause mortality. RESULTS: During the median follow-up of 2.2 [1.2-3.1] years, 310 (5.2%) patients died, of which 236 (4.0%) patients died of cardiovascular disease. CAD patients with elevated uACR had a higher risk of cardiovascular mortality (middle: HR, 2.32; high: HR, 3.22) than those with low uACR, as well as all-cause mortality. Elevated uACR increased nearly 1.5-fold risk of cardiovascular mortality (middle: HR, 2.33; high: HR, 2.34) among patients without T2DM, and increased 1.5- fold to 3- fold risk of cardiovascular mortality in T2DM patients (middle: HR, 2.49; high: HR, 3.98). CONCLUSIONS: Even mildly increased uACR could increase the risk of cardiovascular mortality in patients with CAD, especially when combined with T2DM.

Association between spicy food and hypertension among Han Chinese aged 30-79 years in Sichuan Basin: a population-based cross-sectional study.

BACKGROUND: While spicy food is believed to have cardiovascular-protective effects, its impact on hypertension remains uncertain due to conflicting findings from previous studies. This study aimed to explore the association between spicy food and hypertension in Sichuan Basin, China. METHODS: The baseline data of 43,657 residents aged 30-79 in the Sichuan Basin were analyzed including a questionnaire survey (e.g., sociodemographics, diet and lifestyle, medical history), medical examinations (e.g., height, body weight, and blood pressure), and clinical laboratory tests (e.g., blood and urine specimens). Participants were recruited by multi-stage, stratified cluster sampling in consideration of both sex ratio and age ratio between June 2018 and February 2019. Multivariable logistic regression was performed to explore the effect of spicy food on hypertension and multivariable linear regression was applied to estimate the effect of spicy food on systolic and diastolic blood pressure (SBP/DBP). RESULTS: Concerning hypertension, negative associations with spicy food consumption were observed only in females: compared to those who do not eat spicy food, the odds ratios of consuming spicy food 6-7 days/week, consuming spicy food with strong strength, and years of eating spicy food-to-age ratio were 0.886 (0.799, 0.982), 0.757 (0.587, 0.977), 0.632 (0.505, 0.792), respectively. No significant association was found in males (All P trends > 0.05). In the stratified analyses, participants in the subgroup who were 50 to 79 years old (OR, 95%CI: 0.814, 0.763, 0.869), habitually snored (OR, 95%CI: 0.899, 0.829, 0.976), had a BMI < 24 kg/m2 (OR, 95%CI: 0.886, 0.810, 0.969), had a normal waist circumference (OR, 95%CI: 0.898, 0.810, 0.997), and had no dyslipidemia (OR, 95%CI: 0.897, 0.835, 0.964) showed a significantly stronger association. For SBP, consuming spicy food had negative effects in both genders, but the effect was smaller in males compared to females: among males, the ß coefficients for consuming spicy food 1-2 days/week, weak strength, and years of eating spicy food-to-age ratio were 0.931 (-1.832, -0.030), -0.639 (-1.247, -0.032), and - 2.952 (-4.413, -1.492), respectively; among females, the ß coefficients for consuming spicy food 3-5 days/week, 6-7 days/week, weak strength, moderate strength, and years of eating spicy food-to-age ratio were - 1.251 (-2.115, -0.388), -1.215 (-1.897, -0.534), -0.788 (-1.313, -0.263), -1.807 (-2.542, -1.072), and - 5.853 (-7.195, -4.512), respectively. For DBP, only a positive association between the years of eating spicy food-to-age ratio and DBP was found in males with ß coefficient (95%CI ) of 1.300 (0.338, 2.263); Little association was found in females (all P trends > 0.05), except for a decrease of 0.591 mmHg ( 95%CI: -1.078, -0.105) in DBP among participants who consumed spicy food 1-2 days/week, compared to those who did not consume spicy food. CONCLUSION: Spicy food may lower SBP and has an antihypertensive effect, particularly beneficial for women and individuals with fewer risk factors in the Sichuan Basin. Spicy food consumption may decrease DBP in women but increase it in men. Further multicenter prospective cohort studies are needed to confirm these findings.

Association between alcohol consumption and risk of stroke among adults: results from a prospective cohort study in Chongqing, China.

BACKGROUND: The incidence of stroke in China is increasing, along with a clear trend in the prevalence of risk factors. Alcohol consumption is also a risk factor for stroke. Many cohort studies have explored the relationship between alcohol consumption and stroke risk. However, findings have been inconsistent. METHODS: We used cluster sampling to select 13 districts and counties (at the same level) in Chongqing, China. Then, we used stratified random sampling to distribute the number of people in each district and county. 23,308 adults aged 30-79 were recruited between October 2018 and February 2019. Follow-up was conducted through a monitoring system and questionnaires until September 2022. Information on alcohol consumption and other covariates was collected using a standardized questionnaire. Participants were asked to report their weekly frequency of drinking over the past year and weekly intake of various alcoholic beverages in general. The frequency of drinking was divided into three categories: 1-2 d/week, 3-5 d/week, and 6-7 d/week. The average daily alcohol consumption is calculated based on the amount of alcohol contained in different alcoholic beverages. It is classified as nondrinker (0 g/day), light (0 to 12 g/day), moderate (13 to 36 g/day), and high (> 36 g/day). Cox proportional hazard regression models were used to estimate the association between alcohol consumption and stroke risk. Results are shown as multivariate-adjusted hazard ratios (HRs) and 95% confidence intervals (95% CIs). RESULTS: With an average follow-up of 3.80 years, there were 310 new stroke events. The incidence of total stroke was 368.69 per 100,000 person-years. Overall, after adjusting for covariates, moderate alcohol consumption (average daily alcohol consumption 13-36 g/d) was associated with a lower risk of total stroke (HR: 0.48; 95% CI: 0.25-0.92) compared with nondrinkers. The adjusted HR and 95% CI for total stroke and ischemic stroke for those who drank alcohol 6-7 days per week were 0.60(0.37, 0.96) and 0.53(0.30, 0.94), respectively. The risk of total stroke (HR: 0.39; 95% CI: 0.17-0.89) was reduced in a pattern of drinking 6-7 days per week but with a mean alcohol consumption of less than 36 g/d. There was no significant association between alcohol consumption and hemorrhagic stroke. CONCLUSION: This study suggests moderate alcohol consumption is associated with a lower risk of total stroke. And healthy drinking patterns should be of more significant concern.

Unveiling a New Perspective on Distinguishing Omicron Breakthrough Cases and Postimmune COVID-19-Naive Individuals: Insights from Antibody Profiles.

In the situation of mass vaccination against COVID-19, few studies have reported on the early kinetics of specific antibodies (IgG/IgM/IgA) of vaccine breakthrough cases. There is still a lack of epidemiological evidence about the value of serological indicators in the auxiliary diagnosis of COVID-19 infection, especially when the nucleic acid results were undetectable. Omicron breakthrough cases post-inactivated vaccination (n = 456) and COVID-19-naive individuals with two doses of inactivated vaccination (n = 693) were enrolled. Blood samples were collected and tested for SARS-CoV-2 antibody levels based on the magnetic chemiluminescence enzyme immunoassay. Among Omicron breakthrough cases, the serum IgG antibody level was 36.34 Sample/CutOff (S/CO) (95% confidence interval [CI], 31.89 to 40.79) in the acute phase and 88.45 S/CO (95% CI, 82.79 to 94.12) in the recovery phase. Serum IgA can be detected in the first week post-symptom onset (PSO) and showed an almost linear increase within 5 weeks PSO. Compared with those of breakthrough cases, IgG and IgA titers of the postimmune group were much lower (4.70 S/CO and 0.46 S/CO, respectively). Multivariate regression showed that serum IgG and IgA levels in Omicron breakthrough cases were mainly affected by the weeks PSO (P < 0.001). Receiver operating characteristic ROC0 curve analysis showed that the area under the curve (AUC) was 0.744 and 0.806 when the cutoff values of IgA and IgG were 1 S/CO and 15 S/CO, respectively. Omicron breakthrough infection can lead to a further increase in IgG and IgA levels relative to those of the immunized population. When nucleic acid real-time PCR was negative, we would use the kinetics of IgG and IgA levels to distinguish the breakthrough cases from the immunized population. IMPORTANCE This study fills a gap in the epidemiological evidence by investigating the value of serological indicators, particularly IgG and IgA levels, in the auxiliary diagnosis of COVID-19 infections when nucleic acid results are undetectable. The findings reveal that among Omicron breakthrough cases, both IgG and IgA antibody levels exhibit significant changes. Serum IgG levels increase during the acute phase and rise further in the recovery phase. Serum IgA can be detected as early as the first week post-symptom onset (PSO), showing a consistent linear increase within 5 weeks PSO. Furthermore, receiver operating characteristic (ROC) curve analysis demonstrates the potential of IgG and IgA cutoff values as diagnostic markers. The study's conclusion underscores the importance of monitoring IgG and IgA kinetics in distinguishing Omicron breakthrough cases from vaccinated individuals. These findings contribute to the development of more accurate diagnostic approaches and help inform public health strategies during the ongoing COVID-19 pandemic.
