Abstract
BACKGROUND Vaccination is effective in preventing viral respiratory infectious diseases through protective antibodies and the gut microbiome has been proven to regulate human immunity. This study explores the causal correlations between gut microbial features and serum-specific antiviral immunoglobulin G (IgG) levels. METHODS We conduct a two-sample bidirectional Mendelian randomization (MR) analysis using genome-wide association study (GWAS) summary data to explore the causal relationships between 412 gut microbial features and four antiviral IgG (for influenza A, measles, rubella, and mumps) levels. To make the results more reliable, we used four robust methods and performed comprehensive sensitivity analyses. RESULTS The MR analyses revealed 26, 13, 20, and 18 causal associations of the gut microbial features influencing four IgG levels separately. Interestingly, ten microbial features, like genus Collinsella, species Bifidobacterium longum, and the biosynthesis of L-alanine have shown the capacity to regulate multiple IgG levels with consistent direction (rise or fall). The reverse MR analysis suggested several potential causal associations of IgG levels affecting microbial features. CONCLUSIONS The human immune response against viral respiratory infectious diseases could be modulated by changing the abundance of gut microbes, which provided new approaches for the intervention of viral respiratory infections.

Abstract
Background The current study uniquely focuses on the global incidence and temporal trends of acute hepatitis C (AHC) and hepatitis C virus (HCV)-related cirrhosis among women of reproductive age (15-49 years) from 1990-2019. The risk of vertical transmission and adverse perinatal outcomes associated with HCV infection underscores the importance of prioritising these women in HCV prevention efforts. Methods Leveraging the Global Burden of Disease 2019 data, we calculated age-standardised incidence rates (ASIR) and assessed temporal trends via the average annual percent change from joinpoint regression. The age-period-cohort model was employed to understand further the effects of age, period, and birth cohort. Results Over the 30 years, global incidences of AHC and HCV-related cirrhosis in reproductive-age women increased by 46.45 and 72.74%, respectively. The ASIR of AHC was highest in low sociodemographic index regions but showed a declining trend. Conversely, the ASIR of HCV-related cirrhosis displayed unfavourable trends in low, low-middle, and high sociodemographic index regions. Special attention is necessary for sub-Saharan Africa, high-income North America, Eastern Europe, and Central Asia due to their high incidence rates or increasing trends of AHC and HCV-related cirrhosis. Notably, the age-period-cohort model suggests a recent resurgence in AHC and HCV-related cirrhosis risk. Conclusions The current study is the first to thoroughly evaluate the trends of AHC and HCV-related cirrhosis among reproductive-age women, shedding light on previously unexplored aspects of HCV epidemiology. Our findings identify critical areas where health care systems must adapt to the changing dynamics of HCV infection. The detailed stratification by region and nation further enables the development of localised prevention and treatment strategies.

Abstract
Seed coat mucilage plays an important role in promoting seed germination under adversity. Previous studies have shown that Arabidopsis thaliana MYB52 (AtMYB52) can positively regulate seed coat mucilage accumulation. However, the role of Brassica napus MYB52 (BnaMYB52) in accumulation of seed coat mucilage and tolerance to osmotic stress during seed germination remains largely unknown. We cloned the BnaA09.MYB52 coding domain sequence from B. napus cv ZS11, identified its conserved protein domains and elucidated its relationship with homologues from a range of plant species. Transgenic plants overexpressing BnaA09.MYB52 in the A. thaliana myb52-1 mutant were generated through Agrobacterium-mediated transformation and used to assess the possible roles of BnaA09.MYB52 in accumulation of seed coat mucilage and tolerance to osmotic stress during seed germination. Subcellular localization and transcriptional activity assays demonstrated that BnaA09.MYB52 functions as a transcription factor. RT-qPCR results indicate that BnaA09.MYB52 is predominantly expressed in roots and developing seeds of B. napus cv ZS11. Introduction of BnaA09.MYB52 into myb52-1 restored thinner seed coat mucilage in this mutant to levels in the wild type. Consistently, expression levels of three key genes participating in mucilage formation in developing seeds of myb52-1 were also restored to wild type levels by overexpressing BnaA09.MYB52. Furthermore, BnaA09.MYB52 was induced by osmotic stress during seed germination in B. napus, and ectopic expression of BnaA09.MYB52 successfully corrected sensitivity of the myb52-1 mutant to osmotic stress during seed germination. These findings enhance our understanding of the functions of BnaA09.MYB52 and provide a novel strategy for future B. napus breeding.

Abstract
With the global pandemic of COVID-19, the research on influenza virus has entered a new stage, but it is difficult to elucidate the pathogenesis of influenza disease. Genome-wide association studies (GWASs) have greatly shed light on the role of host genetic background in influenza pathogenesis and prognosis, whereas single-cell RNA sequencing (scRNA-seq) has enabled unprecedented resolution of cellular diversity and in vivo following influenza disease. Here, we performed a comprehensive analysis of influenza GWAS and scRNA-seq data to reveal cell types associated with influenza disease and provide clues to understanding pathogenesis. We downloaded two GWAS summary data, two scRNA-seq data on influenza disease. After defining cell types for each scRNA-seq data, we used RolyPoly and LDSC-cts to integrate GWAS and scRNA-seq. Furthermore, we analyzed scRNA-seq data from the peripheral blood mononuclear cells (PBMCs) of a healthy population to validate and compare our results. After processing the scRNA-seq data, we obtained approximately 70 000 cells and identified up to 13 cell types. For the European population analysis, we determined an association between neutrophils and influenza disease. For the East Asian population analysis, we identified an association between monocytes and influenza disease. In addition, we also identified monocytes as a significantly related cell type in a dataset of healthy human PBMCs. In this comprehensive analysis, we identified neutrophils and monocytes as influenza disease-associated cell types. More attention and validation should be given in future studies.

Abstract
OBJECTIVE This study aimed to systematically evaluate the efficacy, safety and optimal dose of polyethylene glycol loxenatide (PEX168) for treating type 2 diabetes mellitus (T2DM). MATERIALS AND METHODS Clinical trials of PEX168 for T2DM were identified in 8 databases, with a build time limit of January 2023. Included studies were subjected to meta-analysis and trial sequential analysis (TSA). RESULTS On the efficacy endpoint, the meta-analysis showed that PEX168 100 μg significantly reduced 0.86% glycated hemoglobin type A1c (HbA1c) (MD -0.86, 95% CI -1.02 - -0.70, p<0.00001), 1.11 mmol/L fasting plasma glucose (FPG) (MD -1.11, 95% CI -1.49 - -0.74, p<0.00001) and 1.91 mmol/L 2h postprandial glucose (PPG) (MD -1.91, 95% CI -3.35 - -0.46, p=0.01) compared with placebo. The TSA showed that all these benefits were conclusive. On safety endpoints, total adverse events (AEs), gastrointestinal (GI) AEs, serious AEs, and hypoglycemia were comparable to placebo for PEX168 100 μg (p>0.05). In the dose comparison, the HbA1c, FPG, and 2h PPG of PEX168 200 μg were comparable to 100 μg (p>0.05), while GI AEs were significantly higher than 100 μg (RR=2.84, 95% CI 1.64-4.93, p=0.0002). CONCLUSIONS PEX168 100 μg can significantly lower blood glucose and does not increase the risk of total AEs, GI AEs, and hypoglycemia, which may be a preferred glucagon-like peptide-1 receptor agonist for type 2 diabetes mellitus.

Abstract
Introduction Vaccination is still the primary means for preventing influenza virus infection, but the protective effects vary greatly among individuals. Identifying individuals at risk of low response to influenza vaccination is important. This study aimed to explore improved strategies for constructing predictive models of influenza vaccine response using gene expression data. Methods We first used gene expression and immune response data from the Immune Signatures Data Resource (IS2) to define influenza vaccine response-related transcriptional expression and alteration features at different time points across vaccination via differential expression analysis. Then, we mapped these features to single-cell resolution using additional published single-cell data to investigate the possible mechanism. Finally, we explored the potential of these identified transcriptional features in predicting influenza vaccine response. We used several modeling strategies and also attempted to leverage the information from single-cell RNA sequencing (scRNA-seq) data to optimize the predictive models. Results The results showed that models based on genes showing differential expression (DEGs) or fold change (DFGs) at day 7 post-vaccination performed the best in internal validation, while models based on DFGs had a better performance in external validation than those based on DEGs. In addition, incorporating baseline predictors could improve the performance of models based on days 1-3, while the model based on the expression profile of plasma cells deconvoluted from the model that used DEGs at day 7 as predictors showed an improved performance in external validation. Conclusion Our study emphasizes the value of using combination modeling strategy and leveraging information from single-cell levels in constructing influenza vaccine response predictive models.

Abstract
Objective: To investigate the association between remnant cholesterol (RC) and the risk of diabetic retinopathy (DR) in middle-aged and older individuals with diabetes. Methods: Based on the Shanghai Nicheng Cohort Study database, the data of 1 255 individuals with diabetes aged 55-70 years at baseline (2013-2014) with complete fundus photographs and serum cholesterol data in Nicheng, Shanghai, were analyzed. Multinomial logistic regression models were used to evaluate risk ratios (RRs) and their 95% confidence intervals (CIs) between baseline RC level and incident DR. Results: The median age of the subjects was 61.9 years, and 60.4% were women. After a 4.6-year follow-up, 79 (6.3%) patients developed DR, including 50 (4.0%) mild non-proliferative DR and 29 (2.3%) referable DR (RDR). Multivariable logistic regression showed that each mmol/L increase of RC was associated with a 40% higher risk of RDR (RR=1.40, 95%CI 1.03-1.90). Compared with the lowest tertile of RC (<0.63 mmol/L), the risk of RDR in the highest tertile (≥0.85 mmol/L) increased by 4.59 times (RR=5.59, 95%CI 1.51-20.73). Conclusion: The RC level may help identify individuals at high risk of incident RDR in middle-aged and older Chinese adults with diabetes.

Abstract
BACKGROUND Most existing predictive models of hepatocellular carcinoma (HCC) risk after sustained virologic response (SVR) are built on data collected at baseline and therefore have limited accuracy. The current study aimed to construct an accurate predictive model incorporating longitudinal data using a novel modeling strategy. The predictive performance of the longitudinal model was also compared with a baseline model. METHODS A total of 400 patients with HCV-related cirrhosis who achieved SVR with direct-acting antivirals (DAA) were enrolled in the study. Patients were randomly divided into a training set (70%) and a validation set (30%). Informative features were extracted from the longitudinal variables and then put into the random survival forest (RSF) to develop the longitudinal model. A baseline model including the same variables was built for comparison. RESULTS During a median follow-up time of approximately 5 years, 25 patients (8.9%) in the training set and 11 patients (9.2%) in the validation set developed HCC. The areas under the receiver-operating characteristics curves (AUROC) for the longitudinal model were 0.9507 (0.8838-0.9997), 0.8767 (0.6972,0.9918), and 0.8307 (0.6941,0.9993) for 1-, 2- and 3-year risk prediction, respectively. The brier scores of the longitudinal model were also relatively low for the 1-, 2- and 3-year risk prediction (0.0283, 0.0561, and 0.0501, respectively). In contrast, the baseline model only achieved mediocre AUROCs of around 0.6 (0.6113, 0.6213, and 0.6480, respectively). CONCLUSIONS Our longitudinal model yielded accurate predictions of HCC risk in patients with HCV-relate cirrhosis, outperforming the baseline model. Our model can provide patients with valuable prognosis information and guide the intensity of surveillance in clinical practice.

We aimed to assess the efficacy and safety of high-dose, hyperfractionated thoracic radiotherapy of 54 Gy in 30 fractions compared with standard dose (45 Gy in 30 fractions) as a first-line treatment for LS-SCLC. MATERIALS/METHODS The study was an open-label, randomized, phase 3 trial, done at 16 public hospitals in China. Key inclusion criteria were patients aged 18-70 years, with previously histologically or cytologically confirmed LS-SCLC, previously untreated or received 1-2 courses of intravenous cisplatin (75 mg/m²of body-surface area, on day 1 or divided into two days of each cycle) or carboplatin (area under the curve of 5 mg/mL per min, day 1 of each cycle)and intravenous etoposide (100 mg/m²of body-surface area, on days 1-3 of each cycle), and an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1.Eligible patients were randomly assigned (1:1) to receive volumetric-modulated arc radiotherapy (VMAT) of 45 Gy in 30 fractions or the simultaneous integrated boost VMAT (SIB-VMAT) of 54 Gy in 30 fractions to the primary lung tumor and lymph node metastases starting 0-42 days after the first chemotherapy course. Both groups of patients received thoracic radiotherapy twice per day and 10 fractions per week. Prophylactic cranial radiation (PCI, 25 Gy in 10 fractions) was implemented to patients with responsive disease. The primary endpoint was overall survival. Safety was analyzed in the as-treated population. RESULTS Between June 30, 2017, and April 6, 2021, 224 eligible patients were enrolled and randomly assigned to 54 Gy (n = 108) or 45 Gy (n = 116). Median follow-up for the primary analysis was 45 months (IQR 41-48). Median overall survival was significantly improved in the 54 Gy group (62.4 months) compared with the 45 Gy group (43.1 months; p = 0.001). Median progression-free survival was significantly improved in the 54 Gy group (30.5 months) compared with the 45 Gy group (16.7 months; p = 0.044). The most common grade 3-4 adverse events were neutropenia (30 [28%] of 108 patients in the 54 Gy group vs 27 [23%] of 116 patients in the 45 Gy group), neutropenic infections (6 [6%] vs 2 [2%]), thrombocytopenia (13 [12%] vs 12 [10%]), anemia (6 [6%] vs 4 [3%]), and esophagitis (1 [1%] vs 3 [3%]). Treatment-related serious adverse events occurred in 9 [8%] patients in the 54 Gy group and 16 [14%] patients in the 45 Gy group. There were one treatment-related deaths in 54 Gy group (myocardial infarction). CONCLUSION Compared with standard thoracic radiotherapy dose of 45 Gy, the high dose of 54 Gy improved overall survival and progression-free survival without increasing toxicities in patients with LS-SCLC, supporting twice-daily hyperfractionated thoracic radiotherapy of 54 Gy with concurrent chemotherapy is an alternative treatment option for LS-SCLC. This study is complete and registered with ClinicalTrials.gov, NCT03214003.

Abstract
Objective: We explore the candidate susceptibility genes for influenza A virus (IAV), measles, rubella, and mumps and their underlying biological mechanisms.Methods: We downloaded the genome-wide association study summary data of four virus-specific immunoglobulin G (IgG) level data sets (anti-IAV IgG, anti-measles IgG, anti-rubella IgG, and anti-mumps virus IgG levels) and integrated them with reference models of three potential tissues from the Genotype-Tissue Expression (GTEx) project, namely, whole blood, lung, and transformed fibroblast cells, to identify genes whose expression is predicted to be associated with IAV, measles, mumps, and rubella.Results: We identified 19 significant genes (ULK4, AC010132.11, SURF1, NIPAL2, TRAP1, TAF1C, AC000078.5, RP4-639F20.1, RMDN2, ATP1B3, SRSF12, RP11-477D19.2, TFB1M, XXyac-YX65C7_A.2, TAF1C, PCGF2, and BNIP1) associated with IAV at a Bonferroni-corrected threshold of p < 0.05; 14 significant genes (SOAT1, COLGALT2, AC021860.1, HCG11, METTL21B, MRPL10, GSTM4, PAQR6, RP11-617D20.1, SNX8, METTL21B, ANKRD27, CBWD2, and TSFM) associated with measles at a Bonferroni-corrected threshold of p < 0.05; 15 significant genes (MTOR, LAMC1, TRIM38, U91328.21, POLR2J, SCRN2, Smpd4, UBN1, CNTROB, SCRN2, HOXB-AS1, SLC14A1, AC007566.10, AC093668.2, and CPD) associated with mumps at a Bonferroni-corrected threshold of p < 0.05; and 13 significant genes (JAGN1, RRP12, RP11-452K12.7, CASP7, AP3S2, IL17RC, FAM86HP, AMACR, RRP12, PPP2R1B, C11orf1, DLAT, and TMEM117) associated with rubella at a Bonferroni-corrected threshold of p < 0.05.Conclusions: We have identified several candidate genes for IAV, measles, mumps, and rubella in multiple tissues. Our research may further our understanding of the pathogenesis of infectious respiratory diseases.

Abstract
BACKGROUND Socioeconomic status (SES) inequity was recognized as a driver of some certain infectious diseases. However, few studies evaluated the association between SES and the burden of overall infections, and even fewer identified preventable mediators. This study aimed to assess the association between SES and overall infectious diseases burden, and the potential roles of factors including lifestyle, environmental pollution, chronic disease history. METHODS We included 401,009 participants from the UK Biobank (UKB) and defined the infection status for each participant according to their diagnosis records. Latent class analysis (LCA) was used to define SES for each participant. We further defined healthy lifestyle score, environment pollution score (EPS) and four types of chronic comorbidities. We used multivariate logistic regression to test the associations between the four above covariates and infectious diseases. Then, we performed the mediation and interaction analysis to explain the relationships between SES and other variables on infectious diseases. Finally, we employed seven types of sensitivity analyses, including considering the Townsend deprivation index as an area level SES variable, repeating our main analysis for some individual or composite factors and in some subgroups, as well as in an external data from the US National Health and Nutrition Examination Survey, to verify the main results. RESULTS In UKB, 60,771 (15.2%) participants were diagnosed with infectious diseases during follow-up. Lower SES [odds ratio (OR) = 1.5570] were associated with higher risk of overall infections. Lifestyle score mediated 2.9% of effects from SES, which ranged from 2.9 to 4.0% in different infection subtypes, while cardiovascular disease (CVD) mediated a proportion of 6.2% with a range from 2.1 to 6.8%. In addition, SES showed significant negative interaction with lifestyle score (OR = 0.8650) and a history of cancer (OR = 0.9096), while a significant synergy interaction was observed between SES and EPS (OR = 1.0024). In subgroup analysis, we found that males and African (AFR) with lower SES showed much higher infection risk. Results from sensitivity and validation analyses showed relative consistent with the main analysis. CONCLUSIONS Low SES is shown to be an important risk factor for infectious disease, part of which may be mediated by poor lifestyle and chronic comorbidities. Efforts to enhance health education and improve the quality of living environment may help reduce burden of infectious disease, especially for people with low SES.

Abstract
Although integrated care has been considered a key strategy in reforming health systems around the world, it seems hard to realise in practice, particularly in the part of medical social integration. Worse still, little is known about the capacity of social care professionals who implement it, or their perceived roles and responsibilities, as well as the barriers and facilitators that stakeholders from the health and social sectors identify as factors affecting the ICOPE implementation process. Therefore, the present study was performed to probe into these issues. Data were collected from an online survey based on the WHO ICOPE scorecard (N = 34), and focus groups with policy makers, managers, health and social care professionals (N = 47). Inductive analyses were performed in accordance with the service and system levels within the WHO ICOPE implementation framework. While the findings from the scorecard survey highlight the gap in actualizing the ICOPE approach within the existing social services and care structures, we found support for a model of integrated care underpinned by the WHO ICOPE approach. Factors that may hinder and facilitate ICOPE implementation include workforce capacity-building, coordinated networks and partnerships, and financial mechanisms. This finding can help inform subsequent actions that further support health and social care advancement and collaboration, and the implementation of the ICOPE approach.

Abstract
OBJECTIVES Evidence on the effectiveness of cooking activities as a well-being promotion intervention for older adults with subjective cognitive decline (SCD) and their caregivers is scarce. In view of this, a randomized controlled trial was conducted to examine whether a dyadic cooking-based intervention can improve the subjective health and well-being of older adults with SCD and their caregivers, as well as the cooking competence of the former group. DESIGN Randomized controlled trial. SETTING Community. PARTICIPANTS Sixty pairs of community-dwelling older adults aged 60 years or above with SCD (mean age = 78.4 years) and their caregivers (mean age = 65.3 years) were randomly assigned to the intervention group (N = 30 pairs) and the wait-list control group (N = 30 pairs). INTERVENTION The intervention was an innovative 5-week (two hours per week) dyadic cooking-based intervention employing procedural learning methods specifically adapted for older adults with SCD. MEASUREMENTS The outcome measures included 1) a well-being index composed by four indicators: life satisfaction, feeling of happiness, sense of purpose and meaning in life, and perceived health, and 2) cooking competence. RESULTS For both older adults with SCD and their caregivers, the increases in the well-being index were significantly greater in the intervention group than in the control group (β = 0.508, 95% CI [0.036, 0.980]). For older adults with SCD, the increases in the cooking competence score were significantly greater in the intervention group than in the control group (β = 1.629, 95% CI [0.165, 3.071]). CONCLUSION The dyadic cooking-based intervention resulted in improvements in the cooking competence and well-being of older adults with SCD, as well as the well-being of caregivers.

Abstract
OBJECTIVES Intrinsic capacity (IC) declines progressively with age, thereby increasing the risk of disability. However, it is less known whether IC trajectories are associated with disability. This study aims to identify the different patterns of IC trajectories in older people, and examine their determinants and associations with Instrumental Activities of Daily Living (IADL). DESIGN Cohort study. SETTING Community centres in different regions in Hong Kong. PARTICIPANTS AND MEASUREMENTS Longitudinal data from community-dwelling older people aged 60 years or above (n = 1371) collected between 2016 and 2021 was analysed. Their mean age was 74.5 years, and 78.7% of them were female. Repeated measurements of a set of 14 self-reported items were used to generate IC scores at four time points using a bi-factor model. Latent class growth analysis was performed to identify classes with distinct IC trajectories. The association between class membership and IADL disability was then examined using logistic regression. RESULTS Three distinct IC trajectories were identified. The 1st class included those with the highest level of baseline IC and the least declining trajectory, whereas the 3rd class was composed by those with the lowest level of baseline IC and the most declining trajectory. Older age, female gender, lower perceived financial adequacy, living in public or subsidized housing, and chronic diseases were associated with the 3rd class. After adjusting for demographic factors, socioeconomic status, and the number of chronic diseases, the 1st class was more likely to preserve IADL when compared against the 2nd class, with OR being 3.179 (95% CI: 2.152-4.793), whereas for the 3rd class, the OR was 0.253 (95% CI: 0.178-0.359). CONCLUSION Monitoring IC trajectories is of relevance to clinical practice, as it helps shift the focus from treating acute episodes of illness to preserving the functional ability of older people.

Abstract
Sleep can affect nonalcoholic fatty liver disease (NAFLD). We investigated the association between sleep duration, sleep quality, and NAFLD. From January to December 2018, 1,073 patients (age: 37.94 ± 10.88, Body Mass Index (BMI): 22.85 ± 3.27) were enrolled. Pittsburgh Sleep Quality Index Questionnaire and Munich Chronotype Questionnaire were used to assess sleep duration, quality, and habits. Ultrasonography was used to diagnose NAFLD. Multivariate logistic regression models were used to calculate the odds ratio (OR) and 95% confidence interval (CI) of the risk of NAFLD by different types of sleep duration and sleep quality. No significant differences in sleep time, sleep quality, and sleep habits between the NAFLD and the non-NAFLD groups were observed (P > 0.05). There was no correlation between sleep duration and NAFLD in the whole cohort. After adjusting for age, exercise, fasting plasma glucose, and BMI, the group with long sleep duration showed a decreased risk of NAFLD in men (OR = 0.01, 95% CI: 0.001-0.27, P = 0.032). However, in all four adjusted models, no correlation between sleep duration, quality, and NAFLD was found in women. In conclusion, sleep duration was significantly and negatively associated with NAFLD in men but not women. Prospective studies are required to confirm this association.

Abstract
OBJECTIVES Different types of community-based intervention activities may have differential effects in improving the intrinsic capacity (IC) of older people. This study aims to (i) identify subgroups of older people based on their IC impairments, (ii) examine the differential associations between different types of activity participations and change in IC across subgroups, and (iii) assess whether the activity participation patterns of older people align with the way that would benefit them the most. METHODS Participants were community-dwelling older people aged 60 years or above. They were screened for IC impairments at baseline, and their participation records of different types (cognitive, physical, nutritional, mental, and social) of intervention activities were collected for one year. An aggregated IC score was created based on four IC domains including cognitive (self-rated memory), locomotor (self-rated difficulties in walking), vitality (self-rated weight loss), and psychological (subjective well-being). Cluster analysis was used to group homogenous participants. Mixed-effects regression was used to examine the associations between activity counts (i.e., number of sessions participated) and change in IC. Activity participation patterns were also compared across subgroups. RESULTS Data were obtained from 7,357 participants (mean age = 74.72 years). Four clusters were identified, including those who were relatively robust (cluster 1, N = 4,380, 59.5%), those who had cognitive decline (cluster 2, N = 2,134, 29.0%), those who had impaired mobility and vitality (cluster 3, N = 319, 4.3%), and those with poor psychological well-being (cluster 4, N = 524, 7.1%). Overall, activity count was associated with IC improvement (β = 0.073, 95% CI [0.037, 0.108]). However, as regards the cluster-specific results, different types of activities were associated with IC improvement for different specific clusters. For instance, cognitive activity count was associated with IC improvement only for cluster 2 (β = 0.491, 95% CI [0.258, 0.732]). Notably, none of the activity types were associated with IC improvement for cluster 1. Regarding the activity participation patterns, there were no significant differences across the four clusters (Wilk's Λ = 0.997, F = 1.400, p = .138). CONCLUSIONS AND IMPLICATIONS IC improvement depended on the activity types and IC status of older people. In view of this, a people-centred and targeted approach should be adopted to maximize the overall benefits of intervention activities.

Abstract
Purpose It is unclear whether and how the long-term risk of hepatocellular carcinoma (HCC) will change in hepatitis C virus (HCV) infected patients who have reached sustained virologic response (SVR) with direct-acting antivirals (DAA). In this study, we assessed the long-term risk of HCC up to 10 years after SVR using fibrosis 4 score (FIB-4) and its dynamic changes. Patients and Methods A total of 701 DAA-treated patients who achieved SVR between January 2012 to October 2020 were enrolled in the study. The FIB-4 score of each patient was measured at the date of SVR and each follow-up visit annually. Patients were followed until December 31, 2021, with the longest follow-up time being 9.82 years. Results Following SVR, 27 cases of HCC were observed. The annual incidence rate of HCC remained stable with no obvious downward trend. Patients with a FIB-4 >3.25 at baseline or anytime during follow-up were at a higher risk of developing HCC than those whose FIB-4 remained below 3.25. Patients with cirrhosis and patients with no cirrhosis but a FIB-4 >3.25 were at higher risk of developing HCC than patients with no cirrhosis and a FIB-4 ≦3.25. Conclusion FIB-4 >3.25 measured at SVR or any time post-SVR was associated with HCC risks. The repeated measurement of FIB-4 revealed a better predictive ability of HCC risks than the simple measurement of FIB-4 at baseline. The additional stratification of patients by combining FIB-4 and cirrhosis leads to more accurately identifying high-risk patients. Surveillance of HCC is recommended for virologically cured patients with a FIB-4 >3.25 at SVR or anytime afterward and patients diagnosed with cirrhosis.

Abstract
The De Ritis ratio has good diagnostic accuracy in patients with chronic viral liver disease. However, its prognostic utility has remained controversial. This study was to identify different trajectories of De Ritis ratio in those hepatitis C patients cured and analyze relationship between trajectory groups and risk of hepatocellular carcinoma (HCC) with liver-related mortality by the retrospective cohort study. This retrospective longitudinal cohort included 1241 patients with hepatitis C underwent antiviral therapy since follow-up in 2012. De Ritis ratio trajectories were identified by the latent class growth mixed model. Patients were grouped into subgroups by De Ritis ratio according to longitudinal trajectories. The end points were HCC and liver-related mortality. Three distinct trajectory groups were characterized for serum De Ritis ratio: low-stable, middle-stable, and high-rising. 51 HCC and 11 liver-related mortality were recorded and tracked. Comparing to the low-stable group, the adjusted hazard ratios (HRs) and 95% confidence interval (CI) associated with HCC and liver-related mortality were 2.02 (1.12-3.63), 9.36 (3.61-24.29), for the middle-stable, and high-rising group, respectively. Notably, the high-rising trajectory group still had prognostic significance after adjusting for preoperative levels. Likewise, for the high-rising trajectory group of SVR, the HRs (95% CI) were 2.85 (1.03-10.75) for HCC and liver-related mortality, and in patients with cirrhosis, the HRs (95% CI) were 3.44 (1.64-7.19) and 4.35 (1.27- 14.84) in the middle-stable trajectory group and the high-rising trajectory group, respectively. The dynamic measurements of De Ritis ratio are recommended to monitor the prognosis of Hepatitis C patients.

Abstract
Human breast milk is a source of microorganisms for infants that play an important role in building infant gut health and immunity. The bacterial composition in human breast milk is influenced by lactation time. This study aimed to investigate the influence of lactation time on bacteria in breast milk at the genus level and the species levels of Bifidobacterium and Lactobacillus on days 2-4, 8, 14, and 30. Eighteen individuals were recruited and 60 milk samples were collected. The 16S rRNA gene, and the bifidobacterial groEL and lactobacilli groEL genes were used for amplicon sequencing. The results revealed that the alpha diversities of colostrum and transition 1 (day 8) milk were lower than that of transition 2 (day 14) and mature milk. PCoA analysis showed that bacterial composition in colostrum and transition 1 milk differed from transition 2 and mature milk. A lower relative abundance of Blautia was found in colostrum and transition 1 milk compared with mature milk and lower abundances of Ruminococcus, Dorea, and Escherichia-Shigella were found in transition 1 compared with mature milk. Bifidobacterium ruminantium, Limosilactobacillus mucosae, and Ligilactobacillus ruminis were the predominant species across all four lactation stages, while Bifidobacterium bifidum was lower in transition 1, and Bifidobacterium pseudocatenulatum and Bifidobacterium pseudolongum were higher in transition 1 milk. This study indicated that the bacterial composition in colostrum was more similar to that of transition 1 milk, whereas the bacterial community in transition 2 milk was similar to that of mature milk which suggests that bacterial composition in human breast milk shows stage-specific signatures even within a short period at both genus level and Bifidobacterium and Lactobacillus species levels, providing insights into probiotic supplementation for the nursing mother.

Abstract
BackgroundMusculoskeletal (MSK) symptoms affect 50-95% of patients with SLE over their disease course negatively impacting functioning, and quality of life (QoL).1 In SLE-UPDATE, a US, cross-sectional, non-interventional online survey of adults with SLE, over half of the participants reported active MSK symptoms, including pain or swelling in the joints (53%) and stiffness (57%).2 The present study evaluated the sub-group of participants with ‘currently active’ MSK symptoms.ObjectivesTo describe the self-reported disease burden, treatment patterns, and satisfaction with therapies in patients with SLE, comparing those with versus without active MSK symptoms.MethodsThis secondary analysis of SLE-UPDATE survey data stratified participants into active or non-active MSK group. Participants currently experiencing pain or swelling and/or stiffness in their joints and had a Joint Pain NRS > 4 were in the “active MSK group”. All remaining participants were in the “non-active MSK group”. Analysis comprised descriptive statistics, mean (standard deviation [SD]) for continuous variables, and frequency (percentage [%]) for categorical variables. Two-sample t-test to compare mean scores and chi-squared testing to compare proportions were used.ResultsOf the survey participants, 285 were in the active MSK group and 215 in the non-active MSK group. The active MSK group was older (44.3 vs. 40.2 years, <0.001) and had a longer time since diagnosis (12.6 vs. 9.2 years, <0.001). More people in the MSK group had fibromyalgia (FM) (45 vs 12%, <0.0001), worse pain, fatigue, and QoL (Table 1) suggestive of Type 2 non-inflammatory SLE symptoms. Fewer in the MSK group were employed full-time (36.5 vs. 62.8%) and more were on permanent disability (27.0 vs. 6.5%). More participants in the active MSK group negatively assessed their general health (fair or poor) over the last month (53.4 vs. 20.4%). The active MSK group self-reported more “flares” over the prior 3 months; with 44.9 vs 41.9% reporting 1-3 flares, 15.1 vs 5.1% reporting 4-6 flares, and 8.1 vs 2.3% reporting > 7 flares.Table 1.Patient Reported OutcomesActive MSKNon-Active MSKFMNon-FMFMNon-FMN=129N=156N=26N=189Worst Pain NRS, Mean (SD)6.5 (1.7)*4.8 (2.6)6.9 (1.6)*6.2 (1.8)4.0 (2.2)4.9 (2.6)~Worst Joint Pain NRS, Mean (SD)6.7 (1.7)*4.5 (2.6)7.1 (1.6)*6.5 (1.6)3.5 (2.0)4.6 (2.6)*FACIT Fatigue Score, Mean (SD)19.1 (10.8)*28.1 (11.6)15.4 (9.5)*22.1 (10.9)25.7 (13.8)28.4 (11.3)~LupusPRO HRQoL Score (SD)48.9 (20.2)*64.1 (23.0)45.5 (18.1)*51.7 (21.4)63.0 (23.9)64.3 (22.9)~NRS: 0 (none)-10 (worst imaginable); FACIT Fatigue: 0-52, higher= less fatigue; LupusPRO: 0-100, higher= better QoL; *p < 0.05; ~ Not significantThe active MSK group used more anti-malarials (50.9 vs. 30.7%), immunosuppressants (37.2 vs. 26.5%), including methotrexate (12.6 vs 3.3%), narcotic analgesics (18.6 vs. 10.2%), and topicals for joint pain (30.5 vs. 10.2%). Interestingly, treatment goals of greatest importance in both groups were reduction in fatigue and pain, but pain reduction had higher importance in active MSK group (rated very important by 26.7 vs. 18.1%). Lower proportions in the active MSK group were satisfied with steroids (58.0 vs. 77.8% <0.01), immunosuppressants (65.1 vs. 80.7% <0.05), methotrexate (47.2 vs. 85.7% =0.061), and belimumab (80 vs. 95.5%=0.102).ConclusionReduction of pain and fatigue was the main treatment goal of patients with SLE whether they had active or non-active MSK symptoms. Patients with active MSK symptoms had higher pain and fatigue, lower QoL, and less satisfaction with current therapies compared to SLE patients without active MSK symptoms, driven only in part by co-morbid FM. Findings from these analyses suggest there are unmet needs to better understand MSK manifestations, their overlap with Type 2 SLE symptoms, align patient/physician priorities, and improve therapies for MSK symptoms for patients with SLE.References[1]Mahmoud K.

Abstract
To investigate the associations between gene polymorphisms of signal transducer and activator of transcription 3 (STAT3) and liver cirrhosis (LC) after hepatitis B virus (HBV) infection. A case-control study was conducted in 243 patients with hepatitis B cirrhosis (HBV-LC, case group) and 486 HBV-infected subjects without LC (non-LC, control group) collected from January 2018 to September 2020 at the Changsha Central Hospital Affiliated to Nanhua University. Three single nucleotide polymorphisms (SNPs) of STAT3 gene, including rs4796793C>G, rs2293152C>G, and rs1053004T>C were selected through literature and biological information database, and the genotypes were detected by real-time fluorescent quantitative PCR (RFQ-PCR). The distribution differences of STAT3 SNPs genotypes between the two groups were compared using Chi-square test and haplotype analysis was conducted by Shesis online. The proportion of HBV C genotype in HBV-LC patients was significantly higher than that in the control group (80.91% vs. 70.79%, χ2=7.109, P=0.008), while the logarithm of ALT was significantly lower than that of the control group (1.78±0.43 vs. 1.95±0.54, t=3.801, P=0.000). The genotypes distributions of rs4796793, rs2293152, and rs1053004 were not significantly different between HBV-LC and non-LC in overall analysis and stratified analysis by gender (χ²=2.610, 1.505, 0.586, 2.653, 2.685, 1.583, 0.351, 5.388, 0.339, respectively, P>0.05 for each). Among the subjects infected with HBV genotype C, rs1053004 CC (vs. TT) significantly increased the risk of HBV-LC [odds ratio (OR) = 1.40, 95% confidence interval (CI): 1.03-1.91]. Among the HBV-infected subjects with HBeAg negative, rs4796793 GG genotype (vs. CC) and G allele (vs. C) significantly increased the risks of HBV-LC (OR = 2.17, 95%CI: 1.11-4.23; OR = 1.45, 95%CI: 1.06-1.97, respectively). Haplotypes analysis showed that the frequency of haplotype C-G-T composed of rs4796793, rs2293152, and rs1053004 was significantly lower in HBV-LC than that in the control group (non-LC) (27.3% vs. 35.6%, χ²=9.949, P = 0.001). The correlation between STAT3 and HBV-LC is different in HBV-infected subjects with different infection status. The HBV-infected subjects carrying haplotype rs4796793C-rs2293152G-rs1053004T of STAT3 gene have significantly decreased risk of LC.

Abstract
Background Sequential treatment with different generations of anaplastic lymphoma kinase (ALK) inhibitors have been widely applied to ALK-positive lung cancer; however, resistance mutations inevitably developed. Further characterization of ALK resistance mutations may provide key guidance to subsequent therapies. Here we explored the emergence of secondary ALK mutations during sequential ALK tyrosine kinase inhibitor (TKI) treatment in a real-world study of Chinese lung adenocarcinoma (ADC) patients. Methods A clinical-genomic database was queried for lung ADC patients with at least one ALK inhibitor treatment and at least one plasma sample collected following ALK inhibitor treatment. Targeted genome profiling was performed with a 139-gene panel in baseline tumor tissue and serial plasma samples of patients. Results A total of 116 patients met inclusion criteria. ALK G1202R was more common in patients with echinoderm microtubule-associated protein-like 4 (EML4)-ALK v3 fusion, whereas ALK L1196M was more common in v1. TP53 mutant patients were significantly associated with harboring multiple ALK resistance mutations (P = 0.03) and v3+/TP53 mutant patients had the highest rate of multiple ALK resistance mutations. The sequential use of ALK TKI led to an increased incidence of concurrent ALK mutations along the lines of therapies. Alectinib had a lower rate (9%) harboring ALK resistance mutation as first-line ALK TKI compared with crizotinib (36%). ALK compound mutations identified included ALK D1203N/L1196M, ALK G1202R/L1196M, and ALK G1202R/F1174C, which may be lorlatinib resistant. Using paired pretreatment and post-treatment samples, we identified several ALK-independent resistance-related genetic alterations, including PTPRD and CNKN2A/B loss, MYC, MYCN and KRAS amplification, and EGFR19del. Conclusions Sequential postprogression plasma profiling revealed that increased lines of ALK inhibitors can accelerate the accumulation of ALK resistance mutations and may lead to treatment-refractory compound ALK mutations. The selection for optimal first-line TKI is very important to achieve a more efficacious long-term strategy and prevent the emergence of on-target resistance, which may provide guidance for clinical decision making. ALK resistance mutations were differentially enriched in the setting of EML4-ALK v1/v3 and TP53 status. Serial liquid biopsies NGS depicted accumulation of multiple ALK secondary mutations during sequential ALK treatments. Several lorlatinib-resistant ALK compound mutations and ALK-independent resistance genetic alterations were identified.

Abstract
OBJECTIVES Few studies have investigated the link between diet and intrinsic capacity (IC), and the potential sex difference in such association. This study examined the association between dietary patterns and IC and its sub-domains in Chinese community-dwelling older adults. DESIGN Cross-sectional analysis using baseline data from the MrOs and MsOs study. SETTING Community. PARTICIPANTS Chinese community-dwelling older adults aged ≥65 years in Hong Kong. MEASUREMENTS Dietary intake was assessed using a validated food frequency questionnaire and priori and posteriori dietary pattern scores were generated. IC including measures of cognitive, locomotor, vitality, sensory and psychological domains was assessed. Multiple logistic regression was performed to examine the associations between dietary pattern scores and the likelihood of greater IC and sub-domain scores with adjustment for sociodemographic and lifestyle factors. RESULTS Data of 3730 participants (aged 72.2±5.0 years, 50.4% men) was available. In men, higher Diet Quality Index-International (DQI-I) and Okinawan diet scores, and lower "meat-fish" pattern scores were associated with greater IC. A higher DQI-I score was associated with greater locomotion, whereas higher "snacks-drinks-milk products" pattern score was associated with a greater sensory function. In women, none of the dietary pattern scores was associated with IC. Higher DQI-I score, Mediterranean-DASH Intervention for Neurodegenerative Delay Diet (MIND) score and "vegetables-fruits" pattern score were associated with greater psychological function. CONCLUSION Various dietary patterns were associated with greater IC and its sub-domains in Chinese community-dwelling older adults, and more associations were observed in men than women. Strategies to improve diet and IC should take sex differences into account.

Abstract
OBJECTIVES To examine whether intrinsic capacity (IC) could predict frailty, whether declines in specific domains of IC could lead to frailty, and whether different combinations of domains could represent different risks of developing frailty. SETTING Community. PARTICIPANTS Chinese people aged 65 years and older. MEASUREMENTS Using data from a prospective cohort study, we derived a summary score for IC and scores for the five domains (cognitive, locomotor, vitality, sensory, psychological) for each participant at baseline. Frailty was assessed according to the Fried's frailty phenotype at baseline, 2- and 4-year follow-ups. Participants were classified as frail if they had ≥3 of the following criteria: weight loss, self-rated exhaustion, weakness, slow walking speed, and low physical activity. RESULTS Four thousand participants were interviewed at baseline. Overall mean age was 72.5 years; 50% were women. Between baseline and the 2-year follow-up, 5.7% of non-frail participants developed frailty; between 2- and 4-year follow-ups, 5.7% of non-frail participants developed frailty. The average annual incidence rate of frailty was 2.9%. Higher scores on IC at baseline were associated with a lower risk of incident frailty at both follow-ups (year 2, odds ratio (OR)=0.64, 95% confidence interval (CI)=0.59-0.71); year 4, OR=0.64, 95%CI=0.58-0.71) after adjustment for age, sex, educational level, and chronic diseases. Across the five domains, vitality was the strongest predictor of incident frailty at each follow-up (year 2, OR=0.33, 95%CI=0.24-0.45; year 4, OR=0.33, 95%CI=0.23-0.46). Compared to other combinations of any two domains, having 'high' scores on both vitality and locomotor domains was associated with the lowest risk of incident frailty (year 2, OR=0.11, 95%CI=0.06-0.22, area under the curve (AUC)=0.770; year 4, OR=0.18, 95%CI=0.10-0.32, AUC=0.782). CONCLUSION This study provides evidence that IC was independently associated with incident frailty. It also finds that vitality was the domain most strongly associated with incident frailty. Finally, it suggests that optimizing multiple domains of IC, particularly vitality and locomotor, may prevent frailty.

Abstract
Background: Primary biliary cholangitis (PBC) is an autoimmune disease and is often accompanied by thyroid dysfunction. Understanding the potential causal relationship between PBC and thyroid dysfunction is helpful to explore the pathogenesis of PBC and to develop strategies for the prevention and treatment of PBC and its complications. Methods: We used a two-sample Mendelian randomization (MR) method to estimate the potential causal effect of PBC on the risk of autoimmune thyroid disease (AITD), thyroid-stimulating hormone (TSH) and free thyroxine (FT4), hyperthyroidism, hypothyroidism, and thyroid cancer (TC) in the European population. We collected seven datasets of PBC and related traits to perform a series MR analysis and performed extensive sensitivity analyses to ensure the reliability of our results. Results: Using a sensitivity analysis, we found that PBC was a risk factor for AITD, TSH, hypothyroidism, and TC with odds ratio (OR) of 1.002 (95% CI: 1.000–1.005, p = 0.042), 1.016 (95% CI: 1.006–1.027, p = 0.002), 1.068 (95% CI: 1.022–1.115, p = 0.003), and 1.106 (95% CI: 1.019–1.120, p = 0.042), respectively. Interestingly, using reverse-direction MR analysis, we also found that AITD had a significant potential causal association with PBC with an OR of 0.021 (p = 5.10E−4) and that the other two had no significant causal relation on PBC. Conclusion: PBC causes thyroid dysfunction, specifically as AITD, mild hypothyroidism, and TC. The potential causal relationship between PBC and thyroid dysfunction provides a new direction for the etiology of PBC.

Abstract
Objective: To evaluate the differential diagnostic performance of quantitative parameters derived from the spectral CT imagingin pure ground-glass nodules. Methods: A total of 44 patients with pure ground glass nodules underwent chest energy spectrum CT and with known subsequently pathological findings in the Imaging Department of the Second Affiliated Hospital of Soochow University from August 2017 to September 2019 were retrospectively analyzed. Among them, there are 18 males and 26 females, aged from 26 to 79 (51±12) years. They were divided into as the inflammatory group (n=12), pre-invasive adenocarcinoma group (n=17) and invasive adenocarcinoma group (n=15). The aforementioned three groups were further reclassified as non-invasive adenocarcinoma group (inflammatory lesion+pre-invasive lesion) and invasive adenocarcinoma group in order to evaluating the values of water concentration (WC) for the determination of adenocarcinoma infiltration status. The values of WC derived from the arterial and venous phase of the lesion, iodine concentration (IC), standardized iodine concentration (NIC) were measured respectively.The slope of the energy spectral curve (K40-70KeV) derived from the arterial and venous phase of the lesion was also calculated. One-way ANOVA analysis was performed to compare the differences of the three groups and the multiple comparison method was used for further comparing. Intraclass correlation efficient (ICC) was used to assess the consistency of the three times of measurements. The area under curve(AUC) of Receiver Operating Characteristic (ROC) was conducted to evaluate the diagnostic performance of water based values. Results: The values of WC in the arterial and venous phases were significantly different. As in the inflammatory group, the pre-invasive lesion group and the invasive adenocarcinoma group, the values of WC was (291.95±58.66) mg/cm3, (297.61±63.96) mg/cm3and (374.52±60.62) mg/cm3 of the arterial phase, and (277.07±33.78) mg/cm3, (291.74±50.49) mg/cm3 and (373.33±75.12) mg/cm3 of the venous phase, respectively(all P<0.05). Further comparison demonstrated that no significant difference was observed for the values of WC derived from the arterial phases and venous phases between the inflammatory lesion group and the pre-invasive lesion group (all P>0.05).There were an significant differences between the invasive adenocarcinoma group, the inflammatory lesion group and the pre-invasive lesion group (all P<0.05). The values of WC derived from the venous phase achieved the largest AUC (0.770) for differentiating invasive adenocarcinoma from non-invasive adenocarcinoma (inflammatory lesions+pre-invasive lesions) in the pure ground glass nodules. The sensitivity and specificity were 66.67% and 93.10%, respectively, when using 349.31 mg/cm³ as the optimal threshold. The slope of the spectral curve and iodine-related parameters (IC, NIC) derived from arterial or venous phases among the three groups were not significantly different (all P>0.05). Conclusion: The values of WC derived from the spectral CT can better distinguish inflammatory, pre-invasive lesions and invasive adenocarcinoma, which is helpful for the qualitative analysis for pure ground glass nodules.

Abstract
To explore the correlation between the changes of the intestinal flora of newly treated pulmonary tuberculosis patients and the immune indicators of the body, and to provide a reference for the prevention and treatment of pulmonary tuberculosis. A single-center and case-control study was adopted. From October 2020 to April 2021, 43 patients with newly diagnosed tuberculosis in the Department of Tuberculosis, Affiliated Changsha Central Hospital,University of South China were selected as the control group. 43 cases of newly treated pulmonary tuberculosis (PTB), 43 healthy control (HC) during the same period, collected fresh feces and whole blood of subjects, and used Illumina Hiseq high-throughput sequencing technology to analyze 16S of all microorganisms in feces The V4 region of rRNA was amplified and sequenced, and the structure of the intestinal flora was analyzed by QIIME software. Use flow cytometry to determine the subject's immune indicators (CD3+, CD4+, CD8+, CD4+CD25+CD127-Treg, CD14+CD16+, CD14+CD16-), and analyze the changes in intestinal flora and immune function in newly treated pulmonary tuberculosis patients Inherent connection. The χ² test, t test, and Wilcox rank sum test were used to analyze the differences in age, gender, α diversity, and relative abundance of the two groups of people. Compared with the HC group, the alpha diversity of the intestinal flora in the PTB group decreased (shannon index: t=3.906, P=0.000 2; simpson index: Z=553, P=0.004 7; chao1 index: t=5.395, P=0.000 0). β diversity analysis showed that there were significant differences in the structure of the intestinal flora between the two groups (P=0.000). Species difference analysis showed that at the phylum level, the relative abundance of Firmicutes in the PTB group was significantly lower than that in the HC group (Z=486.0, P=0.000 5). At the genus level, there are 15 different bacterial genera between the two groups. In the PTB group, bifidobacterium, enterococcus, lactobacillus, anaerostipes, the relative abundance of the above 5 genera of veillonella is higher than that of the HC group (P<0.05); Butyricimonas, clostridium, and broutella (blautia), coprococcus, dorea, lachnospira, roseburia, faecalibacterium, ruminococcus, the relative abundance of 10 bacterial genera including dialister was lower than that of the HC group (P<0.05). Comparison of immune indexes between groups showed that CD14+CD16+monocytes (%) in the PTB group were higher than those in the HC group (t=2.456, P=0.001 6<0.05), while CD14+CD16-monocytes (%) were lower than HC (t=-4.368, P=0.000<0.05), while the differences in CD3+, CD4+, CD8+, CD4+/CD8+and Treg (CD4+CD25+CD127-) were not statistically significant (P>0.05). Spearman correlation analysis showed that Firmicutes in the PTB group was negatively correlated with CD4+/CD8+, CD14+CD16+(r=-0.218, P=0.048; r=-0.245, P=0.025), and positively correlated with CD14+CD16-Correlation (r=0.250, P=0.022); At the genus level, Faecalis is positively correlated with CD4+/CD8+and CD4+(r=0.250, P=0.023; r=0.258, P=0.019); Rosella and CD3+, CD8+and CD14+CD16-are positively correlated (r=0.27, P=0.024; r=0.219, P=0.046; r=0.027, P=0.039), and negatively correlated with CD14+CD16+(r=-0.280, P= 0.01). Changes in the structure of the intestinal flora of newly treated pulmonary tuberculosis patients may be one of the influencing factors of the immune function of the body. Targeted optimization of the structure of the intestinal flora and improvement of the body's immunity may be used as an effective auxiliary treatment for pulmonary tuberculosis.

Abstract
BACKGROUND The need for strategies to encourage user-initiated reporting of results after HIV self-testing (HIVST) persists. Smartphone-based electronic readers (SERs) have been shown capable of reading diagnostics results accurately in point-of-care diagnostics and could bridge the current gaps between HIVST and linkage to care. OBJECTIVE Our study aimed to assess the willingness of Chinese men who have sex with men (MSM) in the Jiangsu province to use an SER for HIVST through a web-based cross-sectional study. METHODS From February to April 2020, we conducted a convenience web-based survey among Chinese MSM by using a pretested structured questionnaire. Survey items were adapted from previous HIVST feasibility studies and modified as required. Prior to answering reader-related questions, participants watched a video showcasing a prototype SER. Statistical analysis included descriptive analysis, chi-squared test, and multivariable logistic regression. P values less than .05 were deemed statistically significant. RESULTS Of 692 participants, 369 (53.3%) were aged 26-40 years, 456 (65.9%) had ever self-tested for HIV, and 493 (71.2%) were willing to use an SER for HIVST. Approximately 98% (483/493) of the willing participants, 85.3% (459/538) of ever self-tested and never self-tested, and 40% (46/115) of unwilling participants reported that SERs would increase their HIVST frequency. Engaging in unprotected anal intercourse with regular partners compared to consistently using condoms (adjusted odds ratio [AOR] 3.04, 95% CI 1.19-7.74) increased the odds of willingness to use an SER for HIVST. Participants who had ever considered HIVST at home with a partner right before sex compared to those who had not (AOR 2.99, 95% CI 1.13-7.90) were also more willing to use an SER for HIVST. Playing receptive roles during anal intercourse compared to playing insertive roles (AOR 0.05, 95% CI 0.02-0.14) was associated with decreased odds of being willing to use an SER for HIVST. The majority of the participants (447/608, 73.5%) preferred to purchase readers from local Centers of Disease Control and Prevention offices and 51.2% (311/608) of the participants were willing to pay less than US $4.70 for a reader device. CONCLUSIONS The majority of the Chinese MSM, especially those with high sexual risk behaviors, were willing to use an SER for HIVST. Many MSM were also willing to self-test more frequently for HIV with an SER. Further research is needed to ascertain the diagnostic and real-time data-capturing capacity of prototype SERs during HIVST.

Abstract
Psychiatric disorder, including bipolar disorder (BD), major depression (MDD), and schizophrenia (SCZ), affects millions of persons around the world. Understanding the disease causal mechanism underlying the three diseases and identifying the modifiable risk factors for them hold the key for the development of effective preventative and treatment strategies. We used a two-sample Mendelian randomization method to assess the causal effect of insomnia on the risk of BD, MDD, and SCZ in a European population. We collected one dataset of insomnia, three of BD, one of MDD, and three of SCZ and performed a meta-analysis for each trait, further verifying the analysis through extensive complementarity and sensitivity analysis. Among the three psychiatric disorders, we found that only insomnia is causally associated with MDD and that higher insomnia increases the risk of MDD. Specifically, the odds ratio of MDD increase of insomnia is estimated to be 1.408 [95% confidence interval (CI): 1.210–1.640, p = 1.03E-05] in the European population. The identified causal relationship between insomnia and MDD is robust with respect to the choice of statistical methods and is validated through extensive sensitivity analyses that guard against various model assumption violations. Our results provide new evidence to support the causal effect of insomnia on MDD and pave ways for reducing the psychiatric disorder burden.

Abstract
OBJECTIVE The aim of this study was to examine the altering patterns in clinical characteristics and severity of acute post-streptococcal glomerulonephritis (APSGN) in children. PATIENTS AND METHODS We analyzed the medical records of 119 children who were diagnosed with APSGN from 1987 to 2018, retrospectively. The patients were divided into two groups: Group I (n=72, before 1998) and Group II (n=47, after 1998). Clinical, radiologic, and laboratory findings were compared between the two groups. RESULTS The clinical manifestations, including vomiting (20.8% vs. 4.3%, p=0.014), oliguria (40.3% vs. 19.1%, p=0.016), and generalized edema (86.1% vs. 63.8%, p=0.005), were statistically less frequent since 1998. Pulmonary edema on chest X-ray (22.7% vs. 4.4%, p=0.014) was less frequent in Group II than in Group I. The level of BUN (23.3±19.3 vs. 18.8±11.2, p=0.009) was lower in Group II than in Group I, while that of creatinine was not significantly different between the two groups. C3 level was an independent factor for predicting the development of edema (odds ratio [OR]: 1.034, 95% CI: 1.010-1.060, p=0.006) and acute nephritic symptoms (≥2) (OR: 0.974, 95% CI: 0.952-0996, p=0.020). It was also negatively correlated with an increasing number of acute nephritic symptoms, including oliguria and edema, in patients with APSGN (R=-0.182, p=0.048). CONCLUSIONS This study demonstrated that APSGN had favorable clinical manifestations and severity over the past 30 years. The monitoring of C3 levels can be used to assess the disease severity and risk of complications, including edema and oliguria, which are decreasing in South Korean children.

The risk of hepatitis C virus recurrence in hepatitis C virus-infected patients treated with direct-acting antivirals after achieving a sustained virological response: A comprehensive analysis.

Abstract
BACKGROUND & AIMS The risk for hepatitis C virus (HCV) recurrence persists after HCV eradication with direct-acting antivirals (DAAs), particularly in patients with ongoing high-risk behaviours. Our aim was to assess the risk of HCV recurrence (late relapse and/or reinfection) post-sustained virological response (SVR). METHODS We searched the literature for studies reporting HCV recurrence rates post-SVR in PubMed, Web of Science and the Cochrane Library. Identified publications were divided into groups based on patient risk for HCV reinfection: low-risk HCV mono-infection, high-risk HCV mono-infection and a human immunodeficiency virus (HIV)/HCV coinfection. The HCV recurrence rate for each study was calculated by using events divided by the person-years of follow-up (PYFU). HCV recurrence was defined as confirmed, detectable HCV RNA post-SVR. RESULTS In the 16 studies of low-risk patients, the pooled recurrence rate was 0.89/1000 PYFU (95% confidence interval [CI], 0.16-2.03). For the 19 studies of high-risk patients, the pooled recurrence rate was 29.37/1000 PYFU (95% CI, 15.54-46.91). For the eight studies of HIV/HCV-coinfected patients, the pooled recurrence rate was 23.25/1000 PYFU (95% CI, 4.24-53.39). The higher pooled estimates of recurrence in the high-risk and HIV/HCV-coinfected populations were predominantly driven by an increase in reinfection rather than late relapse. CONCLUSIONS The HCV recurrence risk after achieving SVR with all-oral DAAs therapy is low, and the risk of HCV recurrence in high-risk and HIV/HCV-coinfected populations was driven by an increase in reinfection rather than late relapse.

Abstract
OBJECTIVE Due to the quarantine measures during the outbreak of COVID-19, medical schools in China had to shift to online education overnight. Researchers wanted to survey the online medical education status quo and find out the underlying challenges and probable solutions in terms of online medical education to better understand improving and developing medical education in China. METHODS Researchers distributed self-administered and piloted surveys regarding the implementation of online medical education on WeChat and Wenjuanxing. Researchers distributed three phases of online surveys to the undergraduate medical students, and one online survey to the medical teachers on phase three. RESULTS Online medical education was carried out smoothly in China. Seventy-six percent of the students were satisfied with online medical education, and it hardly changed after a month. Courses with the quiz and live-stream courses were rare compared with courses incorporated with other elements. Most parents would remind their children to study online at home. At first, the biggest challenge of learning online was the lagging platform. Nevertheless, as time went by, the major challenge became the learning motivation. Most students thought it necessary to re-teach face-to-face after online education, while most teachers did not think so. CONCLUSION Generally speaking, online medical education was satisfying for both students and teachers, although online courses' diversity with different forms and elements could be enhanced. Infrastructure construction should be considered first for the schools intended to promote online medical education. If the infrastructure were ready, learning motivation would become the biggest challenge for online medical education. Online medical education efficacy evaluation tools need to be developed in the future to narrow the discrepancy of the evaluation between teachers and students.

Abstract
Salt is among the most harmful agents that negatively influences crop yield. Alfalfa is an important perennial forage crop that exhibits wide cultivar variations in salt tolerance. Developing salt-tolerant alfalfa plants is a promising way to utilize salinized land. A comprehensive method was developed to achieve reliable and effective evaluation of alfalfa salt resistance. This included principal components, membership functions and cluster and stepwise regression analyses. These were used to analyse the salt tolerance coefficients of 14 traits and to evaluate 20 diverse alfalfa cultivars at the seedling stage. The various morphological root parameters of six alfalfa cultivars with contrasting salt tolerance were also tested by a scanning apparatus. According to the comprehensive evaluation value (D value), one highly salt-tolerant, two salt-tolerant, four moderately salt-tolerant and 13 salt-sensitive alfalfa cultivars were screened. A mathematical equation for the evaluation of alfalfa salt tolerance was established: D' = -0.126 + 0.667SFW + 0.377SDW + 1.089K+ /Na+ + 0.172SFW/RFW (R2 = 0.988; average forecast accuracy of 96.95%), where four indices were closely related to the salt tolerance: shoot fresh weight, ratio of shoot fresh weight to root fresh weight, shoot dry weight and ratio of K+ to Na+ in the shoot. We also found that SSA correlated strongly with SFW, SDW, K+ /Na+ , D values, while SRV correlated obviously with SFW, SFW/RFW and D values after 150 mm NaCl treatment. In conclusion, the SFW, K+ /Na+ , SDW, SFW/RFW, SSA and SRV could be used as indicators of salt tolerance in alfalfa seedlings grown under 150 mm NaCl treatment.

Abstract
The local structure of NaTiSi_{2}O_{6} is examined across its Ti-dimerization orbital-assisted Peierls transition at 210 K. An atomic pair distribution function approach evidences local symmetry breaking preexisting far above the transition. The analysis unravels that, on warming, the dimers evolve into a short range orbital degeneracy lifted (ODL) state of dual orbital character, persisting up to at least 490 K. The ODL state is correlated over the length scale spanning ∼6 sites of the Ti zigzag chains. Results imply that the ODL phenomenology extends to strongly correlated electron systems.

Abstract
Machine learning (ML) provides novel and powerful ways of accurately and efficiently recognizing complex patterns, emulating nonlinear dynamics, and predicting the spatio-temporal evolution of weather and climate processes. Off-the-shelf ML models, however, do not necessarily obey the fundamental governing laws of physical systems, nor do they generalize well to scenarios on which they have not been trained. We survey systematic approaches to incorporating physics and domain knowledge into ML models and distill these approaches into broad categories. Through 10 case studies, we show how these approaches have been used successfully for emulating, downscaling, and forecasting weather and climate processes. The accomplishments of these studies include greater physical consistency, reduced training time, improved data efficiency, and better generalization. Finally, we synthesize the lessons learned and identify scientific, diagnostic, computational, and resource challenges for developing truly robust and reliable physics-informed ML models for weather and climate processes. This article is part of the theme issue 'Machine learning for weather and climate modelling'.

Abstract
Background Components of liver microenvironment is complex, which makes it difficult to clarify pathogenesis of chronic liver diseases (CLD). Genome-wide association studies (GWASs) have greatly revealed the role of host genetic background in CLD pathogenesis and prognosis, while single-cell RNA sequencing (scRNA-seq) enables interrogation of the cellular diversity and function of liver tissue at unprecedented resolution. Here, we made integrative analysis on the GWAS and scRNA-seq data of CLD to uncover CLD-related cell types and provide clues for understanding on the pathogenesis. Methods We downloaded three GWAS summary data and three scRNA-seq data on CLD. After defining the cell types for each scRNA-seq data, we used RolyPoly and LDSC-cts to integrate the GWAS and scRNA-seq. In addition, we analyzed one scRNA-seq data without association to CLD to validate the specificity of our findings. Results After processing the scRNA-seq data, we obtain about 19,002–32,200 cells and identified 10–17 cell types. For the HCC analysis, we identified the association between B cell and HCC in two datasets. RolyPoly also identified the association, when we integrated the two scRNA-seq datasets. In addition, we also identified natural killer (NK) cell as HCC-associated cell type in one dataset. In specificity analysis, we identified no significant cell type associated with HCC. As for the cirrhosis analysis, we obtained no significant related cell type. Conclusion In this integrative analysis, we identified B cell and NK cell as HCC-related cell type. More attention and verification should be paid to them in future research.

Abstract
OBJECTIVES To document the trend in a quality of life indicator for the older Hong Kong population as an assessment of the impact of age friendly city policies, political conflicts and the covid-19 pandemic. DESIGN Random telephone survey and collection of government data over four years (2017-2020). SETTING Community living older people. PARTICIPANTS People aged 50 years and over. MEASUREMENTS The Hong Kong Quality of Life Index covering four domains of in income security, health status, capability and enabling environment. RESULTS From 2017-9, improvements were seen in various domains in parallel with the adoption of the World Health Organization's Age Friendly City concept by government policy together with a territory wide initiative supported by a major philanthropic organization. However scores of all domains dropped markedly as a result of political conflicts as well as the onset of the pandemic. CONCLUSION The documentation of the trend in HKEQOL shows that while it may be used as a macro indicator that is able to reflect policies affecting the well-being of older people, it is also able to reflect the impact of societal unrest and pandemics, and that the latter may override the effect of existing ageing policies. It also follows that during social unrest and pandemics, specific policies targeting older people may be needed to maintain well-being.

Abstract
OBJECTIVES We examined the structure and predictive ability of intrinsic capacity in a cohort of Chinese older adults. METHODS We used data from the MrOS and MsOS (Hong Kong) study, which was designed to examine the determinants of osteoporotic fractures and health in older Chinese adults. We analysed baseline and the 7-year follow-up data using exploratory factor analysis, confirmatory factor analysis (CFA), and mediation analysis. RESULTS The study consisted of 3736 participants at baseline (mean 72.2 years), with 1475 in the 7-year follow-up. Bi-factor CFA revealed five sub-factors labelled as 'cognitive', 'locomotor', 'vitality', 'sensory', and 'psychological' and one general factor labelled as 'intrinsic capacity'. The model fits the data well, with Root Mean Square Error of Approximation (RMSEA)=0.055 (90% CI=0.053-0.058) for the 5-factor model and RMSEA=0.031 (90% CI=0.028-0.035) for the bi-factor model. Significantly lower intrinsic capacity scores were found in older age groups, women, as well as those who had lower levels of education, lower subjective social status, reported more chronic diseases, or a higher number of IADL limitations (All p<0.0001). Intrinsic capacity had a direct effect in predicting incident IADL limitations at the 7-year follow-up (β=-0.21, p<0.001). The effect was larger than the direct effect of the number of chronic diseases on incident IADL limitations (β=0.05, not significant). CONCLUSIONS This study supports the construct and predictive validity of the proposed capacity domains of intrinsic capacity. The findings could inform the development of an intrinsic capacity score that would facilitate implementation of the concept of intrinsic capacity in clinical practice.

Abstract
OBJECTIVES To examine whether neighborhood social cohesion can alleviate the negative impact of low subjective social status on feelings of loneliness. DESIGN Cross-sectional study. SETTING Community, Hong Kong. PARTICIPANTS Older people who participated in a cohort study on osteoporosis and general health in Hong Kong (MrOs study). METHODS Data were sourced from the 14-year follow-up data of the MrOs study. Loneliness was measured using the 6-item De Jong Gierveld Loneliness Scale. Neighborhood social cohesion was measured by the Hong Kong version of Neighborhood Cohesion Instrument. Linear regression models were used to examine the associations between neighborhood social cohesion and loneliness, controlled for age, sex, marital status, educational level, lifestyle, number of diseases, and maximum lifetime income. The analyses were stratified by subjective social status as measured by a 10-rung self-anchoring scale. RESULTS 1,037 participants with a mean age of 83 years were included in the study, of whom 72%, 83%, and 64% were classified as at risk of overall loneliness, emotional loneliness, and social loneliness, respectively. Those who were classified as at risk of overall loneliness reported lower subjective social status and had lower levels of neighborhood social cohesion. Linear regression models showed that higher levels of neighborhood social cohesion were associated with lower levels of overall and social loneliness. Stratified analyses showed that the associations between neighborhood social cohesion and loneliness vary across subjective social status groups. Among those with low/middle social status ranking, higher levels of neighborhood social cohesion were associated with lower overall (low-ranking B=-0.111, p=0.001; middle-ranking B=-0.057, p=0.026) and social (low-ranking B=-0.093, p<0.001; middle-ranking B=-0.073, p<0.001) loneliness scores. Among those with high ranking, higher levels of neighborhood social cohesion were associated with lower overall (B=-0.099, p=0.041) and emotional (B=-0.056, p=0.017) loneliness scores, but the associations became insignificant when controlling for maximum lifetime income. CONCLUSIONS AND IMPLICATIONS Neighborhood social cohesion may operate differently in different social ranking groups. Interventions to alleviate feelings of loneliness should be subjective social status specific.

Abstract
The aim of this study is to evaluate the relationship between maternal single nucleotide polymorphisms (SNPs) of methylenetetrahydrofolate reductase (MTHFR) gene with plasma homocysteine (HCY) level and offspring congenital heart diseases (CHDs). 338 mothers with offspring CHDs as case group and 306 mothers of normal children as control group were recruited. Their pregnant histories were interviewed by questionnaire and the MTHFR rsl801133 and rsl801131 were genotyped. The case-control analysis was used to find out the relationship between maternal SNPs of MTHFR gene and offspring CHDs. And the plasma HCY concentration of the mothers of CHDs children was detected. This case-case study was intended to find out the relevance between maternal HCY level and SNPs of MTHFR gene. There were significant differences in the gender of children, occupation of mothers, family history with CHDs, history of abortion, history of adverse pregnancy, early pregnancy health, fetus during pregnancy, pesticide exposure and drug exposure in CHDs group and control group (P < 0.05). MTHFR rs1801133 was significantly associated with their offspring CHDs in mothers. The polymorphism of maternal MTHFR rs1801133 increased plasma HCY level, especially the homozygous mutation. Besides the environmental factors, our results suggested that the maternal MTHFR rs1801133 polymorphism might be a risk factor of their offspring CHDs, which may be due to the hyperhomocysteinemia by abnormal metabolism of HCY.
