Background Dyslipidemia is the most important and causal independent risk factor for atherosclerotic cardiovascular disease (ASCVD) . The prevalence of dyslipidemia in elderly residents in Guangdong Province is high, and it is urgent to analyze the specific prevalence of dyslipidemia and its influencing factors among the elderly, and to carry out targeted preventive and control measures for dyslipidemia. Objective To investigate the epidemiological status of dyslipidemia and its risk factors among elderly residents included in the national basic public health service in Yuexiu District, Guangzhou. Methods A total of 41 469 elderly residents aged 65 years and above with complete important variables were selected as subjects from the information system of community health service center in Yuexiu District, Guangzhou City in 2020, the 2020 health checkup data was used to describe the epidemiological characteristics of the included patients such as basic information, BMI and blood lipid levels. Restricted cubic spline (RCS) fitting Logistic regression model was used to analyze the relationship between age, BMI and the prevalence of dyslipidemia. Results The prevalence of dyslipidemia in 41 469 elderly residents was 53.65% (22 247/41 469) , with a standardized prevalence of 53.89%. The prevalence of hypercholesterolemia (HTC) , hypertriglyceridemia (HTG) , mixed hyperlipidemia and low high-density lipoprotein cholesterol was 21.43%, 16.50%, 14.51% and 3.80%, with the standardized prevalence of 21.57%, 16.53%, 14.61%, 3.78%, respectively. Multivariate Logistic regression analysis showed that gender, age, education level, exercise status, and BMI were all influencing factors for dyslipidemia in elderly residents, among which female, low age group, and high BMI were risk factors for dyslipidemia in elderly residents (P

Bioanalysis based on optical imaging has gained significant progress in the last few decades. Luminescence probes are capable of detecting, monitoring, and tracing particular biomolecules in complex biological systems to figure out the roles of these molecules in organisms. Considering the rapid development of luminescence probes for bio-applications and their promising future, we have attempted to explore the working principles and recent advances in bio-applications of luminescence probes, in the hope of helping readers gain a detailed understanding of luminescence probes developed in recent years. In this review, we first focus on the current widely used luminescence probes, including fluorescence probes, bioluminescence probes, chemiluminescence probes, afterglow probes, photoacoustic probes, and Cerenkov luminescence probes. The working principles for each type of luminescence probe are concisely described and the bio-application of the luminescence probes is summarized by category, including metal ions detection, secretion detection, imaging, and therapy.

Background: Investigating adherence to the Atrial Fibrillation Better Care (ABC) pathway management and identifying gaps between the real world and established guidelines can lead to better integrated management of AF. Current data on adherence to ABC pathway management among community elderly patients with atrial fibrillation (AF) in Chinese communities is limited.Aim: To investigate the adherence to ABC pathway management among community elderly patients with AF in China.Methods: In this cross-sectional study, data were collected from the 2020 National Basic Public Health Service Program database that includes health examination information for all residents > 65 years of age in Yuexiu, Guangzhou, Guangdong Province. Demographic and clinical characteristics data from 197 community AF patients were obtained.Results: Among the 197 AF patients, 103 (52.3%) were male, 117 (59.4%) were ≥ 75 years of age, 127 (64.5%) had a senior middle school education or above, 84.3% were married, and 195 (99.0%) had medical insurance. The most common comorbidities were hypertension (72.1%, 142/197), dyslipidaemia (28.4%, 56/197), CAD (28.9%, 57/197), and diabetes (24.9%, 49/197). In terms of the ABC management pathway, 21.8% (43/197), 82.7% (163/197), and 31.5% (62/197) of AF patients were classified into the A-adherent group, B-adherent group, and C-adherent group, respectively. The level of adherence to ABC pathway management was very low (9.1%, 18/197) and independently associated with age and multimorbidity.Conclusion: The level of adherence to ABC pathway management in community elderly patients with AF was unsatisfactory. Further research is warranted to improve the integrated management of AF.

To implement the human–robot interactions in a noisy environment, the speech improvement-based (SIB) stratified adaptive finite-time saturation control (SAFTSC) for omnidirectional service robot (OSR) is developed. From the outset, the feature vectors of nine designed speech commands are extracted from their frequency signals and then trained by multiclass support vector machine. Two background noises are on-line filtered with the characteristic: “the smaller error in power spectrum is, the larger recovery from noisy power spectrum is.” Comparisons among without or with noise, and filtering are addressed. To achieve the zero pose error of OSR in finite time, an adaptive finite-time indirect trajectory (AFTIT) is constructed. To track the AFTIT with the zero error in finite time, the adaptive finite-time saturation control (AFTSC) is also established. Both AFTIT and AFTSC possess nonlinear switching gain increasing the high-frequency motion capability to fulfill the classified speech command. Simply put, the proposed SIB stratified AFTSC includes the speech improvement for classification, the AFTIT, and the AFTSC. Besides the stability of the closed-loop system is verified by the Lyapunov stability theory, three categories of SIB experiments are compared. [ABSTRACT FROM AUTHOR]
