Independent and joint relationships of cardiorespiratory fitness and body mass index with liver fat content.

AIMS: To investigate the relationship between cardiorespiratory fitness (CRF) and liver fat content (LFC) in community-based participants and highlight their relationship in people with different body mass indices (BMIs). MATERIALS AND METHODS: Using UK Biobank data, CRF was estimated with bicycle ergometer fitness testing and was evaluated based on physical work capacity at 75% maximum heart rate (PWC75%). LFC was quantified through liver proton density fat fraction (PDFF) on magnetic resonance imaging. Multivariate linear regression models were used to analyse the associations of CRF and BMI with absolute reduction and percentage change in PDFF (%). RESULTS: In total, 5765 participants with a mean age of 55.57 years and a median (range) follow-up of 10.7 (4.0-17.7) years were included. Compared with the lowest PWC75% tertile, the absolute reduction and percentage change in PDFF in the highest PWC75% tertile were -0.450 (95% confidence interval [CI] -0.699 to -0.192) and -4.152 (95% CI -6.044 to -2.104), respectively. These associations were independent of BMI, and individuals with obesity and normal weight had the largest absolute reduction and percentage change in LFC, respectively (p for interaction <0.001). Joint analysis showed that PWC75% and BMI had a negative dose-response relationship with PDFF. These associations were consistent in different sex and age subgroups (p for interaction >0.05). CONCLUSIONS: There was a significant negative association between CRF and LFC, and this association was independent of BMI. The results of this study strongly recommend improving CRF to mitigate LFC.

Association between metabolic dysfunction-associated fatty liver disease and abdominal aortic aneurysm.

BACKGROUND AND AIMS: Abdominal aortic aneurysm (AAA) is the second most common aortic pathological manifestation. Metabolic dysfunction-associated fatty liver disease (MAFLD) has a wide impact on the cardiovascular system and may be a risk factor for AAA. The aim of this study was to investigate whether MAFLD is associated with the risk of AAA. METHODS AND RESULTS: We used data from the prospective UK Biobank cohort study. MAFLD is defined as hepatic steatosis plus metabolic abnormality, type 2 diabetes, or overweight/obesity. AAA is collected by ICD-10 code. Cox regression was established to analyze the association between MAFLD and AAA. A total of 370203 participants were included; the average age of the participants was 56.7 ± 8.0 years, and 134649 (36.4 %) were diagnosed with MAFLD. During the 12.5 years of follow-up, 1561 (0.4 %) participants developed AAA. After fully adjusting for confounding factors, individuals with MAFLD had a significantly increased risk of AAA (HR 1.521, 95 % CI 1.351-1.712, p < 0.001). Importantly, the risk of AAA increases with the severity of MAFLD as assessed by fibrosis scores. These associations were consistent according to sex, weight, and alcohol consumption but weaker in elderly or diabetics (P for interaction <0.05). The association between the MAFLD phenotype and AAA was independent of the polygenic risk score. Additionally, MAFLD was not associated with thoracic aortic aneurysm or aortic dissection events. CONCLUSIONS: There was a significant relationship between MAFLD and AAA. These findings strongly recommend early prevention of AAA by intervening in MAFLD.

Emerging Trends in Teledermatology Research: A Scientometric Analysis from 2002 to 2021.

Background: With advances in technology, teledermatology (TD) research has increased. However, an updated comprehensive quantitative analysis of TD research, especially one that identifies emerging trends of TD research in the coronavirus disease 2019 (COVID-19) era, is lacking. Objective: To conduct a scientometric analysis of TD research documents between 2002 and 2021 and explore the emerging trends. Methods: CiteSpace was used to perform scientometric analysis and yielded visualized network maps with corresponding metric values. Emerging trends were identified mainly through burst detection of keywords/terms, co-cited reference clustering analysis, and structural variability analysis (SVA). Results: A total of 932 documents, containing 27,958 cited references were identified from 2002 to 2021. Most TD research was published in journals from the "Dermatology" and "Health Care Sciences & Services" categories. American, Australian, and European researchers contributed the most research and formed close collaborations. Keywords/terms with strong burst values to date were "primary care," "historical perspective," "emerging technique," "improve access," "mobile teledermoscopy (TDS)," "access," "skin cancer," "telehealth," "recent finding," "artificial intelligence (AI)," "dermatological care," and "dermatological condition." Co-cited reference clustering analysis showed that the recently active cluster labels included "COVID-19 pandemic," "skin cancer," "deep neural network," and "underserved population." The SVA identified two reviews (Tognetti et al. and Mckoy et al.) that may be highly cited in the future. Conclusion: During and after the COVID-19 era, emerging trends in research on TD (especially mobile TDS) may be related to skin cancer and AI as well as further exploration of primary care in underserved areas.

Reliability of the risk of bias assessment in randomized controlled trials for nursing: A cross-sectional study.

AIM: To evaluate the percentage and reasons for disagreements in the risk of bias (RoB) assessments for randomized controlled trials (RCTs) included in more than one Cochrane review in the field of nursing. BACKGROUND: Disagreement in RoB assessments reduces the credibility of the evidence summarized by systematic reviews (SRs). There is no study that evaluates the reliability of RoB assessments in nursing studies. DESIGN: Secondary data analysis based on research reports. METHODS: RCTs included in more than one review in the nursing have been included. The disagreement of the assessment was analysed, and the possible reasons for disagreements were investigated. RESULTS: Twenty-three RCTs were included in more than one review. The agreement of assessment ranged from 36.84% for "selective reporting" to 91.30% for "random sequence generation". "Allocation concealment" showed the optimal agreement (84.21%). The items "blinding of participants and personnel", "blinding of outcome assessment" and "incomplete outcome data" showed poor agreement, with 50.00%, 58.82% and 66.67%, respectively. Most disagreements came from extracting incomplete or different RCTs' information. CONCLUSIONS: The level of agreement of the assessment between reviews has varied greatly in the field of nursing. More complete and accurate information of RCTs needs to be collected when conducting a SR.

Multi-system diseases and death trajectory of metabolic dysfunction-associated fatty liver disease: findings from the UK Biobank.

BACKGROUND: Metabolic dysfunction-associated fatty liver disease (MAFLD) is a newly defined condition encompassing hepatic steatosis and metabolic dysfunction. However, the relationship between MAFLD and multi-system diseases remains unclear, and the time-dependent sequence of these diseases requires further clarification. METHODS: After propensity score matching, 163,303 MAFLD subjects and 163,303 matched subjects were included in the community-based UK Biobank study. The International Classification of Diseases, Tenth Revision (ICD-10), was used to reclassify medical conditions into 490 and 16 specific causes of death. We conducted a disease trajectory analysis to map the key pathways linking MAFLD to various health conditions, providing an overview of their interconnections. RESULTS: Participants aged 59 (51-64) years, predominantly males (62.5%), were included in the study. During the 12.9-year follow-up period, MAFLD participants were found to have a higher risk of 113 medical conditions and eight causes of death, determined through phenome-wide association analysis using Cox regression models. Temporal disease trajectories of MAFLD were established using disease pairing, revealing intermediary diseases such as asthma, diabetes, hypertension, hypothyroid conditions, tobacco abuse, diverticulosis, chronic ischemic heart disease, obesity, benign tumors, and inflammatory arthritis. These trajectories primarily resulted in acute myocardial infarction, disorders of fluid, electrolyte, and acid-base balance, infectious gastroenteritis and colitis, and functional intestinal disorders. Regarding death trajectories of MAFLD, malignant neoplasms, cardiovascular diseases, and respiratory system deaths were the main causes, and organ failure, infective disease, and internal environment disorder were the primary end-stage conditions. Disease trajectory analysis based on the level of genetic susceptibility to MAFLD yielded consistent results. CONCLUSIONS: Individuals with MAFLD have a risk of a number of different medical conditions and causes of death. Notably, these diseases and potential causes of death constitute many pathways that may be promising targets for preventing general health decline in patients with MAFLD.

Angiogenesis in Aortic Aneurysm and Dissection: A Literature Review.

Aortic aneurysm and aortic dissection (AA/AD) are critical aortic diseases with a hidden onset and sudden rupture, usually resulting in an inevitable death. Several pro- and anti-angiogenic factors that induce new capillary formation in the existing blood vessels regulate angiogenesis. In addition, aortic disease mainly manifests as the proliferation and migration of endothelial cells of the adventitia vasa vasorum. An increasing number of studies have shown that angiogenesis is a characteristic change that may promote AA/AD occurrence, progression, and rupture. Furthermore, neocapillaries are leaky and highly susceptible to injury by cytotoxic agents, which promote extracellular matrix remodeling, facilitate inflammatory cell infiltration, and release coagulation factors and proteases within the wall. Mechanistically, inflammation, hypoxia, and angiogenic factor signaling play important roles in angiogenesis in AA/AD under the complex interaction of multiple cell types, such as smooth muscle cells, fibroblasts, macrophages, mast cells, and neutrophils. Therefore, based on current evidence, this review aims to discuss the manifestation, pathological role, and underlying mechanisms of angiogenesis involved in AA/AD, providing insights into the prevention and treatment of AA/AD.

Association between malnutrition and stroke-associated pneumonia in patients with ischemic stroke.

BACKGROUND: Malnutrition is associated with a high risk of mortality in adults with ischemic stroke (IS). This study aimed to investigate the relationship between malnutrition and the risk of stroke-associated pneumonia (SAP) as only a few studies examined the relationship between malnutrition and the risk of SAP in IS. METHODS: Patients were included from emergency departments of five tertiary hospitals in the REtrospective Multicenter study for Ischemic Stroke Evaluation (REMISE) study from January 2020 to December 2020. Malnutrition was defined according to the Controlling Nutritional Status (CONUT), Geriatric Nutritional Risk Index (GNRI), and Prognostic Nutritional Index (PNI) systems. Multivariable logistic regression analysis was used to explore the association between malnutrition and risk of SAP. RESULTS: We enrolled 915 patients with IS, 193 (14.75%), 495 (54.1%), and 148 (16.2%) of whom were malnourished according to the PNI, CONUT, and GNRI scores, respectively. SAP occurred in 294 (32.1%) patients. After adjusting for confounding influencing factors in the logistic regression analysis, malnutrition (moderate and severe risk vs. absent malnutrition) was independently associated with an increased risk of SAP based on the PNI (odds ratio [OR], 5.038; 95% confidence interval [CI] 2.435-10.421, P < 0.001), CONUT (OR, 6.941; 95% CI 3.034-15.878, P < 0.001), and GNRI (OR, 2.007; 95% CI 1.186-3.119, P = 0.005) scores. Furthermore, adding malnutrition assessment indices to the A2DS2 score significantly improved the ability to predict SAP by analysis of receiver operating characteristic curves and net reclassification improvement. CONCLUSION: Malnutrition was notably prevalent in patients with IS and independently associated with an increased risk of SAP. Further studies are required to identify the effect of interventions on malnutrition to reduce the risk of SAP.

Subclinical cardiovascular disease and frailty risk: the atherosclerosis risk in communities study.

BACKGROUND: Cardiovascular disease (CVD) is associated with a greater frailty risk, but it remains unknown if pathways that contribute to CVD are associated with the frailty risk. Thus, we aimed to investigate whether elevations in high-sensitivity cardiac troponin T (hs-cTnT) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) for those without known CVD at baseline are associated with a higher frailty risk. METHODS: This study used data from the Atherosclerosis Risk in Communities study. Cardiac biomarkers were measured from stored plasma samples collected at Visit 2 (1991-1993). Frailty was recorded at Visit 5 (2011-2013). Cox regression models were used to determine the association of cardiac biomarkers with frailty risk. RESULTS: Overall, 360/5199 (6.9%) participants aged 55.1 ± 5.1 years developed frailty during a median follow-up of 21.7 years. The incidence of frailty was significantly higher in participants with hs-cTnT ≥14 ng/L (vs. < 14 ng/L: 17.9% vs. 6.7%) or NT-proBNP ≥300 pg/ml (vs. < 300 pg/ml: 19.7% vs. 6.8%) (all P < 0.001). Comparing higher vs. lower cut-off levels of either hs-cTnT (14 ng/l) or NT-proBNP (300 pg/ml) demonstrated a greater than two-fold higher frailty risk, with hazard ratios (HRs) of 2.13 (95% confidence interval (CI): 1.130-4.01, P = 0.020) and 2.61 (95% CI: 1.28-5.33, P = 0.008), respectively. Individuals with both elevated hs-cTnT and NT-proBNP had a higher frailty risk than those without it (HR: 4.15; 95% CI: 1.50-11.48, P = 0.006). CONCLUSIONS: High hs-cTnT and NT-proBNP levels are strongly associated with incident frailty in the community-dwelling population without known CVD. Subclinical cardiac damage (hs-cTnT) and/or wall strain (NT-proBNP) may be the key pathway of CVD patients developing frailty. Detection of hs-cTnT and NT-proBNP may help for early screening of high-risk frailty and providing individualised intervention. TRIAL REGISTRATION: URL: https://www.

Development of a performance measurement system for general practitioners' office in China's primary healthcare.

BACKGROUND: General practitioners are the main providers of primary care services. To better strengthen the important role of general practitioners in primary healthcare services, China is promoting the general practitioners' office system. There is a lack of well-accepted methods to measure the performance of general practitioner offices in China. We thus aim to develop a systematic and operable performance measurement system for evaluating the general practitioner's office. METHODS: We establish an index pool of the performance measurement system of general practitioners' offices by a cross-sectional study and the literature research method and adopt the focus group method to establish the preliminary system. The Delphi method is then used to conduct three rounds of consultation to modify indices, which aims to form the final indicator system. We determine the weight of each index by the analytic hierarchy process method, which together with the final indicator system constitutes the final performance measurement system. Finally, we select three offices from three different cities in Sichuan Province, China, as case offices to conduct the case study, aiming to assess its credibility. RESULTS: Our results show that the first office scored 958.5 points, the second scored 768.1 points, and the third scored 947.7 points, which corresponds to the reality of these three offices, meaning that the performance measurement system is effective and manoeuvrable. CONCLUSIONS: Our study provides support for standardizing the functions of China's general practitioner's office, improving the health service quality of generalists, and providing a theoretical basis for the standardization of the general practitioner's office.

Psychological Distress Reported by Primary Care Physicians in China During the COVID-19 Pandemic.

OBJECTIVE: Primary care physicians (PCPs) play a key role in responding to the COVID-19 epidemic. The objective of this study was to explore the influencing factors associated with self-reported psychological distress among a sample of PCPs in China in relation to COVID-19. METHODS: An online survey was distributed to a sample of PCPs in Chengdu city between February 10 and February 13, 2020. The survey consisted of three sections: demographic characteristics, COVID-19-related questions, and the General Health Questionnaire-12 (GHQ-12). After 5 months, a follow-up survey investigating the change of the GHQ-12 was conducted. RESULTS: A total of 712 PCPs completed the baseline survey (11.8% of those invited), 55.6% were female and 74.4% were aged between 30 and 49 years. High levels of psychological distress (GHQ-12 ≥3) were observed in 29.2% and were associated with low preparedness, high work impact, working with infected residents, personal life impact, and concerns, as well as older age and being married (p values < .05). Logistic regression analysis showed that psychological distress was associated with low preparedness (odds ratio [OR] = 0.91, 95% confidence interval [CI] = 0.87-0.96), high work impact (OR = 1.11, 95% CI = 1.03-1.20), personal life impact (OR = 1.12, 95% CI = 1.07-1.17), and safety-related concerns (OR = 1.09, 95% CI = 1.02-1.16). At the 5-month assessment point, high psychological distress was less frequent (21.8%). CONCLUSIONS: COVID-19 has resulted in high levels of distress in approximately 30% of PCPs in China. Factors associated with high psychological distress levels include low preparedness and high levels of work impact, personal life impact, and concerns. These findings highlight the importance of enhancing psychological health throughout the course of infectious pandemics.

Nutritional Risk Screening 2002 was associated with acute kidney injury and mortality in patients with acute coronary syndrome: Insight from the REACP study.

BACKGROUND AND AIMS: Acute kidney injury (AKI) is a common complication of acute coronary syndrome (ACS), and is associated with increased risk of morbidity and mortality. We aimed to evaluate the impact of malnutrition risk at admission assessed using Nutritional Risk Screening 2002 (NRS-2002) on AKI and mortality in patients with ACS. METHODS AND RESULTS: We enrolled 3185 ACS patients from the retrospective multi-centre study. AKI was defined as criteria of the 2012 Kidney Disease Improving Global Outcomes. Risk of malnutrition was defined as NRS-2002 score ≥3. The end points were AKI and all-cause mortality. There were 926 (29.1%) patients with risk of malnutrition and 481 (15.1%) patients complicated with AKI during hospitalisation, and 378 (12.0%) patients died during the 13.1 (8.5-20.4) months of follow-up. Patients with NRS-2002 score ≥3 had a higher incidence of AKI and all-cause mortality (P < 0.001). Multivariate logistic and Cox regression analysis showed that the adjusted odd ratios and hazard ratios of categorised NRS-2002 (<3 vs. ≥3) for AKI and mortality were 1.643 (95% confidence interval: 1.242-2.172, P < 0.001) and 2.026 (95% confidence interval: 1.491-2.753, P < 0.001), respectively. In structural equation modelling, the indirect effects of NRS-2002 on mortality via AKI were 54.1% (P < 0.001). CONCLUSION: The risk of malnutrition assessed using NRS-2002 was useful in identifying high-risk patients with AKI and mortality, and patients with ACS may benefit from further nutritional intervention and prevention of AKI.

Community-based rehabilitation service in Chengdu, Southwest China: a cross-sectional general survey.

BACKGROUND: World Health Organization initiated community-based rehabilitation (CBR) in 1978, and by now, it has been an essential process of medical services worldwide. China had strengthened primary health care on building more than 35,000 community health centers (CHCs) in cities, and more than 34,000 township health centers (THCs) in the rural area. Nevertheless, it remains unclear that if these primary health centers could provide optional rehabilitation services for disabilities. And this study aims at evaluating the supply capacity of rehabilitation service in primary health centers of Chengdu, a regional center city of southwest China. METHOD: We conducted a general investigation of primary health centers in Chengdu, a city located in southwest China with more than 15 million population. Our investigation covered all of Chengdu's 390 primary health centers from October to November 2016. We researched these primary health centers on basic rehabilitation services, diseases, and rehabilitation equipment quantity and quality, and traditional Chinese medicine (TCM) physiotherapy. RESULT: Rehabilitation therapy is available in 88.9% (337 of 379) of all primary health centers. Meanwhile, CHCs slightly surpass THCs with an available rate of 92.2% (106 of 115) and 87.5% (231 of 264), respectively. Traditional Chinese Medicine (TCM) physiotherapy is available in 97.1% (368 of 379) of all primary health centers, 97.3% (112 of 115) of CHCs and 97.0% (256 of 264) of THCs. Quantitative analysis showed that substantial factors which could make an impact on the number of patients per year contain: categories of rehabilitation disease (P < 0.001, 95% confidence interval (CI) [- 1.571, - 0.702]),number of rehabilitation bed (P < 0.001, 95%CI [- 1.249, - 0.290]). CONCLUSION: CBR and TCM physiotherapy has become accessible for disabilities in most basic health centers of Chengdu City, whereas, available rate of CBR in THCs is lesser than in CHCs, which suggests an imbalance in primary health service development between rural and urban area. Categories of rehabilitation diseases, and the number of rehabilitation beds constitute co-factors that make an impact on the CBR capacity of basic health centers.

Association of alpha-ADD1 Gene and Hypertension Risk: A Meta-Analysis.

BACKGROUND: Results regarding the association between a-adducin (ADD1) gene and essential hypertension (EH) risk remain inconsistent. Therefore, we performed this meta-analysis to investigate this association. MATERIAL AND METHODS: We comprehensively searched published literature from PubMed and Embase. All studies analyzing the association between ADD1 Gly460Trp polymorphism and EH risk were included. Fixed- or random-effects model was used to calculate pooled odds ratio (OR) with 95% confidence interval (CI). RESULTS: Data synthesis showed an increased risk of EH in T allele variant carriers with Asian descent, for GG vs. TT (OR=0.750, 95%CI: 0.585-0.960; P=0.022), recessive model (OR=1.196, 95%CI: 1.009-1.418; P=0.039), dominant model (OR=0.826, 95%CI: 0.693-0.985; P=0.033), and allelic model (OR=0.859, 95%CI: 0.756-0.964; P=0.01), respectively. However, no statistical differences were observed in Blacks and Caucasians. CONCLUSIONS: The findings showed the association of the T allele in ADD1 gene with EH susceptibility in Asians. However, well-designed studies involving gene-gene and gene-environment interactions should be considered in future.

[Risk factors associated with chronic obstructive pulmonary disease: a comparison between urban and rural populations in Chengdu].

OBJECTIVE: To determine risk factors associated with the prevalence of chronic obstructive pulmonary disease (COPD) in urban and rural populations in Chengdu. METHODS: A multistage random cluster sampling method was adopted to select participants from four communities in Chengdu. All residents aged 40-70 yr. were eligible to participate in this study, which involved a questionnaire survey, physical examination and portable spirometry. Those with airflow limitations were also given post-bronchodilator testing 15 min after inhalation of a dose of 200 microg salbutamol. We defined a forced expiratory volume in one second/forced vital capacity (FEV1/FVC) of less than 70% as COPD. Logistic regression models were performed to identify risk factors of COPD. RESULTS: Of a total of 1931 eligible participants, 1579 (81.77%) completed the questionnaire and spirometry. About 8.35% were identified with COPD: 7.69% in urban vs. 12.37% in rural (P<0.05). The prevalence of COPD increased with age (P<0.05) in the male and total populations. Rural COPD patients had a higher level of smoking rate and use of coal as fuel for cooking than their urban counterparts (P<0.05). But rural COPD patients had a lower level of BMI, waist circumference, literacy, and average household income per capita than their urban counterparts (P<0.05). The multivariate analysis showed that tobacco smoking index (pack-year), education, age and BMI were predictors of COPD for male patients; whereas, coal fuel usage, income and BMI were predictors of COPD for female patients. CONCLUSION: COPD prevalence is higher in rural areas than in urban Chengdu. Major risk factors of COPD include smoking, coal fuels and BMI.

Association of T174M polymorphism of angiotensinogen gene with essential hypertension: A meta-analysis.

The association between T174M polymorphism of angiotensinogen gene and essential hypertension risk remains controversial. We herein performed a meta-analysis to achieve a reliable estimation of their relationship. All the studies published up to May 2013 on the association between T174M polymorphism and essential hypertension risk were identified by searching the electronic repositories PubMed, MEDLINE and EMBASE, Springer, Elsevier Science Direct, Cochrane Library and Google Scholar. Data were extracted and pooled odds ratios (ORs) with 95% confidence intervals (95% CIs) were calculated. Ultimately, nine eligible studies, including 2188 essential hypertension cases and 2459 controls, were enrolled in this meta-analysis. No significant associations were found under the overall ORs for M-allele comparison (M vs. T, pooled OR 0.92, 95% CI 0.62-1.37), MM vs. TT (pooled OR 0.86, 95% CI 0.29-2.51), TM vs. TT n (pooled OR 0.91, 95% CI 0.63-1.32), recessive model (MM vs. TT+TM, pooled OR 0.89, 95% CI 0.35-2.30), dominant model (MM+TM vs. TT, pooled OR 0.91, 95% CI 0.60-1.38) between T174M polymorphism and risk for essential hypertension. This meta-analysis suggested that the T174M polymorphism of the angiotensinogen gene might not be associated with the susceptibility of essential hypertension in Asian or European populations.

[Levels of serum lipids in rural populations with diabetes and pre-diabetes in Chengdu].

OBJECTIVE: To investigate the serum lipid levels in rural residents with diabetes and pre-diabetes conditions in Chengdu. METHODS: Random cluster sampling method was employed to select participants of 35-70 year-old rural residents in Chengdu. The participants (n=971) were given standard 75 g oral glucose tolerance tests (OGTT) and divided into five groups: impaired fasting glucose (IFG) group, impaired glucose tolerance (IGT) group, IFG and IGT (IFG+ IGT) group, diabetes mellitus (DM) group and normal glucose tolerance (NGT) group. Their serum total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-c) and low density lipoprotein cholesterol (LDL-c) were measured. RESULTS: The age-adjusted standardized prevalence of DM and pre-diabetes in rural residents in Chengdu were 12.8% and 34.5%, respectively, without significant gender differences. IGT was the most common type of abnormal glucose metabolism in pre-diabetes. High serum TG and LDL-c and low serum HDL-c were found in 45.9%, 30.6% and 9.9% participants with DM, respectively. High serum LDL-c and TG and low serum HDL-c were found in 38.1%, 30.6% and 7.6% of participants with IGR. Participants with DM or/and IGR had higher levels of LDL-c and TG and lower levels of HDL-c than those in the NGT group. CONCLUSION: Pre-diabetes and diabetes are prevalent in rural residents in Chengdu, which are usually accompanied with various degrees of dyslipidemia.

[Research on expression and function of phosphorylated DARPP-32 on pentylenetetrazol-induced epilepsy model of rat].

The present study is to explore the change process and distribution of phosphorylated DARPP-32 (p-DARPP-32) in rat brain including cortex, hippocampus and striatum and to further deduce whether p-DARPP-32 was possibly involved in epilepsy induced by repetitive low doses of pentylenetetrazol (PTZ). PTZ-induced epilepsy model in rat was established with 30 male SD rats randomly divided into 6 groups, control group and five trial groups [PTZ 1 h, PTZ 6 h, PTZ 24 h, PTZ 48 h and PTZ 72 h respectively, after onset of status epilepticus (SE)]. Immunohistochemistry and immunofluorescence double-labeling were used to detect the temporal time change and distribution of p-DARPP-32 expression and to analyze the coexpression of DARPP-32 and p-DARPP-32 in rat brain after the onset of PTZ-induced generalized SE. The results showed that there was a temporal time change of p-DARPP-32 expression in rat brain after the onset of SE. The number of p-DARPP-32-positive cells increased significantly and reached the peaks at the ends of 1 hour and 6 hours after the onset of SE, but decreased at the end of 24 hours. The moderate to strong p-DARPP-32-immunopositive neurons were observed in cortex, hippocampus and striatum, and located in cell cytoplasm and cell nucleus. Further immunofluorescence double-labeling revealed that denser colocalization of p-DARPP-32 and DARPP-32 in the neurons existed in the area mentioned above. Therefore, PTZ-induced SE may cause phosphorylation of DARPP-32 in rat brain. The temporal time change and distribution of p-DARPP-32 suggest that phosphorylation of DARPP-32 may be involved in PTZ-induced epilepsy in rat brain including cortex, hippocampus and striatum, and p-DARPP-32 may play a central role in the onset of SE.

Intervention strategies for management of comorbid depression among individuals with hypertension: a scoping review protocol.

INTRODUCTION: Hypertension and depression often coexisted, leading to poor health outcome and significant challenges in healthcare management. Since no guidelines or consensus are available for health professionals to manage this comorbidity, identifying interventions in current literature is crucial for gaining a clear picture of evidence and informing future research directions and clinical practice. This scoping review is designed to address this gap by systematically mapping the range of potential interventions for managing comorbid hypertension and depression. METHODS AND ANALYSIS: Following the Joanna Briggs Institute guidelines for scoping review, this review will comprehensively search databases including PUBMED, Embase, PsycINFO, CINAHL, Cochrane Library Databases, Chinese Biomedical Literature Database and Chinese National Knowledge Infrastructure. Grey literature will be sourced from Google Scholar. A year limit of January 2004-December 2023 will be applied to retrieve the most current peer-reviewed articles in English and Chinese language only. Two reviewers will individually screen and the process will be documented in Preferred Reporting Items for Systematic Reviews and Meta-Analyses for scoping reviews. This review will explore a range of non-pharmacological and multicomponent interventions including psychosocial support, educational programmes, telemedicine and integrated healthcare models. Data extraction will follow the Template for Intervention Description and Replication checklist to ensure detailed and standardised reporting of intervention components. The synthesis of findings will employ both quantitative and qualitative methods to provide a comprehensive overview of the intervention landscape. ETHICS AND DISSEMINATION: This scoping review, which involves secondary data analysis of publicly available sources, does not require ethical approval. Findings will be disseminated through peer-reviewed publications and presentations at relevant conferences. STUDY REGISTRATION: Open Science Framework registry (osf.io/j7gt8) in Centre for Open Science on 29 January 2024.

Disagreements in risk of bias assessment for randomized controlled trials in hypertension-related Cochrane reviews.

BACKGROUND: The inter-reviewer reliability of the risk of bias (RoB) assessment lacked agreement in previous studies. It is important to analyse these disagreements to improve the repeatability of RoB assessment. The objective of the study was to evaluate the frequency and reasons for disagreements in RoB assessments for randomised controlled trials (RCTs) that were included in multiple Cochrane reviews in the field of hypertension. METHODS: A cross-sectional study was employed. We retrieved any RCTs that had been included in multiple Cochrane reviews in the field of hypertension from ARCHIE. The results of the RoB assessments were extracted, and the distributions of agreements and possible reasons for disagreement were analyzed. RESULTS: Twenty-six Cochrane reviews were included in this study. A total of 78 RCTs appeared in more than one Cochrane review. The level of agreement ranged from domain to domain. "Blinding of outcome assessment" showed a reasonably high level of agreement (94.9%), while "incomplete outcome data", "selective outcome reporting" and "other sources of bias" showed moderate levels of agreement (74.6%, 79.2% and 75.6%, respectively). However, the domains of "allocation concealment", "random sequence generation" and "blinding of participants and personnel" showed low levels of agreement (24.4%, 23.5%, and 47.4%, respectively). In the domains of "allocation concealment" and "blinding of participants and personnel", the agreement group had higher proportion of publication year ≤ 1996 than the disagreement group (P = 0.008 and P < 0.001, respectively). In the "blinding of participants and personnel", the impact factor was higher in the agreement group (P < 0.001). By analyzing the support text, we found that the most likely reason for disagreement was extracting different information from the same RCT. CONCLUSION: For Cochrane reviews in the field of hypertension using the 2011 version of the RoB tool, there was a large disagreement in the RoB assessment. It is suggested that the results of RoB assessments in systematic reviews that used the 2011 version of the RoB tool need to be interpreted with caution. More accurate information from RCTs needs to be collected when we synthesize clinical evidence.

Copublication promotes dissemination hypertension guidelines: a retrospective cohort study.

To evaluate the impact of copublication on hypertension-related clinical practice guidelines' citation, we searched the Web of Science Core Collection and guide.medlive.cn until 31 December 2017 using the terms "hypertension" and "guideline". The copublished group was matched with the noncopublished group at a 1:2 ratio. Primary outcomes were total citations and citations within the first five years after publication. Secondary outcomes included the adjusted impact factor ratio (excluding copublished guidelines) to the actual impact factor of the journal. Altmetric scores were compared using Altmetric explorer data. 21 copublished and 42 noncopublished guidelines were included. The copublished group had higher median current total citations [387.0 (90.0, 1806.0) vs 70.5 (23.25, 158.25)], and higher median citations at one, two, three, four, and five years [7.0 (0.5, 58.5) vs 1.0 (0.0, 5.5), 33.0 (14.0, 142.0) vs 5.5 (1.75, 26.25), 46.0 (24.5, 216.0) vs 10.5 (3, 25.75), 50.0 (19.0, 229.0) vs 9.0 (3.0, 19.0), 52.0 (13.5, 147.0) vs 7.0 (2.0, 20.0), all p < 0.05]. The adjusted IF analysis showed that if they had not copublished the guidelines, 10 of 24 and 11 of 24 journals would have had a lower IF in the first and second years. Median altmetric scores were significantly higher for copublished guidelines [38.5 (9.5, 90.5) vs 3.5 (1.0, 9.0)] (p < 0.05). Copublication is associated with a higher citation frequency of hypertension guidelines and may increase the journal IF. Positive impacts extend beyond academia, benefiting society through broader guideline application and dissemination. This facilitates broader application of guidelines and promotes their dissemination. We conducted a retrospective cohort study to demonstrate how copublication promotes the dissemination of hypertension guidelines.
