Dose health education on dementia prevention have more effects on community residents when a community physician/nurse leads it? A cross-sectional study

BackgroundDementia is a growing public health concern worldwide. Community residents still have limited knowledge about dementia prevention, although many sources are accessible for individuals to acquire knowledge.MethodsA questionnaire-based survey was conducted in five communities in Chongqing, China, between March 2021 and February 2022. Participants were divided into three groups according to the dementia-related education they received: physician/nurse-led, mass media, and no relevant education. Covariance analysis was performed to determine the differences among the three groups in knowledge, motivation, and lifestyle, with the covariate of MoCA scores (education-adjusted).ResultsOf the 221 participants, 18 (8.1%) received physician/nurse-led education, 101 (45.7%) received only mass media education, and 102 (46.2%) did not receive any relevant education regarding dementia prevention. Participants who only received mass media education had a higher level of education (t = 5.567, p = 0.004) and cognitive function (t = 13.978, p < 0.001). The analysis of covariance showed that compared with participants who received no relevant education, those who received physician/nurse-led education had higher levels of knowledge, perceived benefits, and better lifestyle, and those who received mass media education had lower perceived barriers; however, higher levels of cues to action, general health motivation, self-efficacy, and lifestyle (all p < 0.05).ConclusionThe popularization of dementia-related education was not ideal for communities. Physician/nurse-led education plays a vital role in providing knowledge and promoting lifestyles for dementia prevention, but may not motivate community residents. Mass media education may help encourage residents and promote their lifestyles

Combination of Neutrophil Count and Gensini Score as a Prognostic Marker in Patients with ACS and Uncontrolled T2DM Undergoing PCI

Background: Several biomarkers have been studied as prognostic indicators among people with diabetes and coronary artery disease (CAD). The purpose of this study was to determine the prognostic value of neutrophil counts and the Gensini score in patients with diabetes and ACS undergoing percutaneous coronary intervention (PCI). Methods: A total of 694 people with ACS and T2DM who simultaneously had elevated HBA1c received PCI. Spearman rank correlation estimates were used for correlation evaluation. Multivariate Cox regression and Kaplan-Meier analysis were used to identify characteristics associated with major adverse cardiovascular and cerebrovascular events (MACCEs) and patient survival. The effects of single- and multi-factor indices on MACCEs were evaluated through receiver operating characteristic curve analysis. Results: The Gensini score and neutrophil count significantly differed between the MACCE and non-MACCE groups among patients receiving PCI who had concomitant ACS and T2DM with elevated HBA1c (P<0.001). The Gensini score and neutrophil count were strongly associated with MACCEs (log-rank, P<0.001). The Gensini score and neutrophil count, alone or in combination, were predictors of MACCEs, according to multivariate Cox regression analysis (adjusted hazard ratio [HR], 1.005; 95% confidence interval [CI], 1.002–1.008; P=0.002; adjusted HR, 1.512; 95% CI, 1.005–2.274; P=0.047, respectively). The Gensini score was strongly associated with neutrophil count (variance inflation factor ≥ 5). Area under the curve analysis revealed that the combination of multivariate factors predicted the occurrence of MACCEs better than any single variable. Conclusion: In patients with T2DM and ACS with elevated HBA1c who underwent PCI, both the Gensini score and neutrophil count were independent predictors of outcomes. The combination of both predictors has a higher predictability

Association between plasma trimethylamine N -oxide and neoatherosclerosis in patients with very late stent thrombosis

Abstract(#br)Background(#br)Trimethylamine N -oxide (TMAO) has been shown to promote the development of atherosclerosis. However, the relationship between plasma TMAO and neoatherosclerosis, an important underlying mechanism of very late stent thrombosis (VLST), is unknown.(#br)Methods(#br)This post hoc study investigated the association between TMAO and neoatherosclerosis in two independent cohorts. These included a control group of 50 healthy volunteers and a study cohort of 50 patients with VLST who presented with ST-segment elevation myocardial infarction and underwent optical coherence tomography examination. Of the 50 patients with VLST, 23 had neoatherosclerosis and 27 did not have neoatherosclerosis. Patients with neoatherosclerosis were further divided into two subgroups, including 14 patients with plaque rupture and 9 without plaque rupture.(#br)Results(#br)The plasma TMAO levels, detected using mass spectrometry, were significantly higher in patients with VLST than in healthy individuals (median [interquartile range]: 2.50 [1.67-3.84] vs. 1.32 [0.86-2.44] μM; P < 0.001). Among the VLST patients, the plasma TMAO levels were significantly higher in patients with neoatherosclerosis than in those without neoatherosclerosis (3.69 [2.46-5.29] vs. 1.96 [1.39-2.80] μM; P<0.001). In addition, in patients with neoatherosclerosis, patients with plaque rupture had significantly higher plasma TMAO concentrations than those without plaque rupture (4.51 [3.41-5.85] vs. 2.46 [2.05-3.55] μM; P=0.005). Multivariate analysis indicated that TMAO was an independent predictor of neoatherosclerosis (odds ratio 3.41; 95% confidence interval: 1.59-7.30; P=0.002). Moreover, the area under the receiver operating characteristic curve for TMAO, differentiated by neoatherosclerosis, was 0.85.(#br)Conclusions(#br)Plasma TMAO was significantly correlated with neoatherosclerosis and plaque rupture in patients with VLST

Primary Percutaneous Coronary Intervention in Patients With Type 2 Diabetes With Late/Very Late Stent Thrombosis and de novo Lesions: A Single-Center Observational Cohort Study of Clinical Outcomes and Influencing Factors

Background: This study compared differences in the risk factors and clinical outcomes of primary percutaneous coronary intervention (PCI) in type 2 diabetes mellitus (DM) and non-DM patients with de novo lesions (DNLs) and late or very late stent thrombosis (LST/VLST).Methods: We used angiography to screen 4,151 patients with acute coronary syndrome for DNL and LST/VLST lesions. Overall, 3,941 patients were included in the analysis and were allocated to the DM (n = 1,286) or non-DM (n = 2,665) group at admission. The primary endpoint was a composite of major adverse cardiovascular events (MACEs), defined as death, myocardial infarction, revascularization, and ischemic stroke, within a median follow-up period of 698 days.Results: In the group with a total white blood cell count &gt;10 × 109/L (P = 0.004), a neutral granular cell count &gt;7 × 109/L (P = 0.030), and neutrophil–lymphocyte ratio &gt;1.5 (P = 0.041), revascularization was better for DNL than for LST/VLST lesions. Among DM patients with DNLs, each unit increase in age was associated with a 53.6% increase in the risk of MACEs [hazard ratio (HR): 1.536, 95% confidence interval (CI), 1.300–1.815, P &lt; 0.0001]. Older age (≥65 years) was associated with a significantly greater risk of MACEs (P &lt; 0.0001). Furthermore, each standard deviation (SD) increase in the level of peak white blood cell counts was associated with a 50.1% increase in the risk of MACEs (HR, 1.501; 95% CI, 1.208–1.864; P = 0.0002). When stratifying the DM population with DNLs according to the D-dimer baseline and peak levels &lt;0.5 vs. ≥0.5 mg/L, the high D-dimer group at baseline had a 2.066-fold higher risk of MACEs (P &lt; 0.0001), and the high peak level D-dimer group had a 1.877-fold higher risk of MACEs (P = 0.001) compared to the low-level groups. Among DM patients with LST/VLST, each unit increase in age was associated with a 75.9% increase in the risk of MACEs (HR: 1.759, 95% CI, 1.052–2.940, P = 0.032). Furthermore, for each SD increase in the peak D-dimer level, the risk of MACEs increased by 59.7% (HR, 1.597; 95% CI, 1.110–2.295; P = 0.041).Conclusion: Following successful primary PCI, the measurement of baseline and peak D-dimer values may help identify individuals at high cardiovascular risk. This suggests a potential benefit of lowering D-dimer levels among T2DM patients with DNL. Furthermore, age and the peak D-dimer values may facilitate the risk stratification of T2DM patients with LST/VLST

OsteoporosAtlas: a human osteoporosis-related gene database

Background Osteoporosis is a common, complex disease of bone with a strong heritable component, characterized by low bone mineral density, microarchitectural deterioration of bone tissue and an increased risk of fracture. Due to limited drug selection for osteoporosis and increasing morbidity, mortality of osteoporotic fractures, osteoporosis has become a major health burden in aging societies. Current researches for identifying specific loci or genes involved in osteoporosis contribute to a greater understanding of the pathogenesis of osteoporosis and the development of better diagnosis, prevention and treatment strategies. However, little is known about how most causal genes work and interact to influence osteoporosis. Therefore, it is greatly significant to collect and analyze the studies involved in osteoporosis-related genes. Unfortunately, the information about all these osteoporosis-related genes is scattered in a large amount of extensive literature. Currently, there is no specialized database for easily accessing relevant information about osteoporosis-related genes and miRNAs. Methods We extracted data from literature abstracts in PubMed by text-mining and manual curation. Moreover, a local MySQL database containing all the data was developed with PHP on a Windows server. Results OsteoporosAtlas (http://biokb.ncpsb.org/osteoporosis/), the first specialized database for easily accessing relevant information such as osteoporosis-related genes and miRNAs, was constructed and served for researchers. OsteoporosAtlas enables users to retrieve, browse and download osteoporosis-related genes and miRNAs. Gene ontology and pathway analyses were integrated into OsteoporosAtlas. It currently includes 617 human encoding genes, 131 human non-coding miRNAs, and 128 functional roles. We think that OsteoporosAtlas will be an important bioinformatics resource to facilitate a better understanding of the pathogenesis of osteoporosis and developing better diagnosis, prevention and treatment strategies

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Major leaching processes of combustion residues : characterisation, modelling and experimental investigation

Characterising leaching behaviour provides ample evidence toidentify the majorleaching processes of combustion residues.Neutralisation and chemical weatheringgovern the leachingreactions and control the release of major, minor and traceelementsfrom combustion residues, and are thus considered to bethe major leaching processes. Several geochemical models are used to describe theneutralisation and chemicalweathering processes based onleaching kinetics and the features of leaching systems.Areaction path model is used to evaluate the neutralisingprocesses in a batch system. Theneutralising processes in aflow-through system are assessed using an equilibriumreactivetransport model which accounts for most neutralising reactionsunder the experimental conditions. A kineticreactive transportmodel taking full kineticconsideration for heterogeneousreactions is used to simulate long-term chemicalweathering. According to experimental investigations and geochemicalsimulations, the leachingkinetics of buffering materials arekey issues for the understanding of the neutralisingprocesses.The acid neutralising capacity (ANC) at different pH levelsdepends mainly onthe mineralogy of the combustion residues. Thetime-dependent and pH-dependent neutralising behaviours aredetermined by the matrix phases of a solid waste. Incombustionresidues, the dissolution of glass phases is expected to playan important rolein a long-term neutralising process. Theneutralising process in a flow system issignificantly differentfrom that in a batch system. In general, the informationobtainedfrom batch experiments cannot directly to be used in aflow system. The neutralising ability of a combustion residuemay be strongly affected by solute transport and carbonationreactions in a natural leaching environment. The chemical weathering mainly involves the matrix ofcombustion residues consistingmostly of glass phases. Thedissolution kinetics of waste glass and other possibleprocesses involved in the chemical weathering have beeninvestigated and incorporatedinto a kinetic reactive transportmodel. Most important processes in the chemical weathering canbe simulated simultaneously using this model. The results showthat thereis a complicated relationship between the factorscontrolling the long-term chemicalweathering. The dissolutionof the waste matrix is strongly affected by itsdissolutionkinetics and weathering environment. Theenvironmental impact of the glass dissolutioncannot beneglected. Although the glass dissolution provides considerablebufferingcapacity in long-term weathering, the carbonate isusually a dominant buffering mineralin actual weatheringprocesses. The transformation of carbonate should be consideredasan important process in the chemical weathering. Theformation of secondary minerals,clay-like minerals (e.g.illite) and amorphous silica, may considerably alter themineralogy of the waste, and thus change the leachingbehaviours of the combustion residue duringlong-term chemicalweathering.
