Analysis of spiritual well-being status and influencing factors in patients with esophageal cancer: a cross-sectional study.

OBJECTIVE: To understand the status of spiritual well-being in patients with esophageal cancer and analyze its influencing factors. METHODS: A total of 187 patients with esophageal cancer (EC) from two grade A hospitals in Chengdu were selected and investigated by general data questionnaire, chronic disease function evaluation-spirituality scale 12 (FACIT-SP-12), general well-being scale (GWB), and Anderson symptom assessment scale gastrointestinal tract (MDASI-GI). RESULTS: The spiritual well-being score of patients with esophageal cancer was (25.13 ± 9.63). Spiritual well-being was positively correlated with general well-being and negatively correlated with symptom burden (P < 0.01). The results of multiple stepwise linear regression analysis showed that hobbies, disease stage, general well-being, and symptom burden were the main influencing factors for the spiritual well-being of esophageal cancer patients (P < 0.05), explaining 49.0% of the total variation. CONCLUSIONS: The spiritual well-being of patients with esophageal cancer is lower than the middle level, In addition, whether there is a hobby in life, disease stage, subjective well-being, and symptom burden are the main factors affecting the spiritual well-being of patients with EC. It is suggested that medical staff should take targeted care measures according to the influencing factors, so as to improve the spiritual well-being level of patients and improve the quality of life of patients.

Health-related quality of life in Chinese SLE patients: evidence from 1568 SLE patients and 2610 healthy controls.

OBJECTIVE: To investigate the effects of systemic lupus erythematosus (SLE) on health-related quality of life (HRQOL), the relationship between disease activity and HRQOL, and potential factors affecting HRQOL in Chinese SLE patients. METHODS: This study recruited 1568 patients and 2610 controls to explore the effects of SLE on HRQOL. The association between disease activity and HRQOL, and the influencing factors of HRQOL were determined in 1568 patients. Then, we prospectively followed 1096 patients to explore the association between reduced disease activity and improved HRQOL, and the influencing factors of improved HRQOL. The Short-Form 36 (SF-36) and SLE disease activity index (SLEDAI) were used to evaluate HRQOL and disease activity. RESULTS: Chinese SLE patients had lower HRQOL than controls in all domains (P < 0.001), especially in role-physical (RP) and role-emotional (RE). Compared with SLE patients from outside China, the HRQOL of Chinese patients appeared to be higher in mental component summary (MCS) but lower in RP and RE. SLEDAI was negatively correlated with HRQOL, which was validated using the results of a follow-up study, where SLEDAI reduction was positively associated with HRQOL improvements (P < 0.05). Furthermore, personality, life nervous and experiences of adverse life events may influence HRQOL and HRQOL improvements. CONCLUSION: SLE significantly affected the HRQOL of Chinese patients, especially in RP and RE. Disease activity was negatively correlated with HRQOL. We also found for the first time some factors affecting HRQOL, which can be regarded as the basis for improving the HRQOL of SLE patients.

Factors associated with nocturnal and diurnal glycemic variability in patients with type 2 diabetes: a cross-sectional study.

PURPOSE: There is little information on factors that influence the glycemic variability (GV) during the nocturnal and diurnal periods. We aimed to examine the relationship between clinical factors and GV during these two periods. METHODS: This cross-sectional study included 134 patients with type 2 diabetes. 24-h changes in blood glucose were recorded by a continuous glucose monitoring system. Nocturnal and diurnal GV were assessed by standard deviation of blood glucose (SDBG), coefficient of variation (CV), and mean amplitude of glycemic excursions (MAGE), respectively. Robust regression analyses were performed to identify the factors associated with GV. Restricted cubic splines were used to determine dose-response relationship. RESULTS: During the nocturnal period, age and glycemic level at 12:00 A.M. were positively associated with GV, whereas alanine aminotransferase was negatively associated with GV. During the diurnal period, homeostatic model assessment 2-insulin sensitivity (HOMA2-S) was positively associated with GV, whereas insulin secretion-sensitivity index-2 (ISSI2) was negatively associated with GV. Additionally, we found a J-shape association between the glycemic level at 12:00 A.M. and MAGE, with 9.0 mmol/L blood glucose level as a cutoff point. Similar nonlinear associations were found between ISSI2 and SDBG, and between ISSI2 and MAGE, with ISSI2 value of 175 as a cutoff point. CONCLUSION: Factors associated with GV were different between nocturnal and diurnal periods. The cutoff points we found in this study may provide the therapeutic targets for beta-cell function and pre-sleep glycemic level in clinical practice.

Examining multidimensional health poverty and determining factors among rural women of childbearing age in ningxia, china.

BACKGROUND: The multidimensional health poverty afflicting rural women of reproductive age bears profound implications for the sustainable development of families, societies, and healthy villages. Elucidating vulnerable groups at risk of multidimensional health poverty and delineating its determinants can inform refinements and implementation of health-poverty alleviation policies. METHODS: Based on the 2022 "Health Status and Health Service Utilization" survey data in rural Ningxia, China, this study analyzes the dimension of health status, capacity for health service utilization, health expenditure and security using the A-F dual-threshold method, logit model, and probit model. It comprehensively evaluates multidimensional health poverty and analyzes its determining factors among rural women of childbearing age. RESULTS: With k set at 0.3, the health multidimensional poverty index, incidence, and intensity among rural women of reproductive age were 0.021, 0.053, and 0.392, respectively. Chronic illness, capacity for free gynecological examination utilization, health examination utilization, and borrowing due to illness contributed significantly to multidimensional health poverty. Risk factors for multidimensional health poverty among rural women of childbearing age include age, unemployment, family size, and lack of sanitary toilets. Protective factors include being married, educational level, non-farm or student occupation, receiving government support, separate housing and kitchen, owning a television and computer. CONCLUSIONS: Even with the elimination of absolute poverty, the multidimensional health poverty situation among rural women remains important from a gender perspective. It is recommended to strengthen economic assistance and health service support for these groups, improve the level of rural health services from a gender perspective, and enhance housing structure and sanitation toilet usage in rural areas. Efforts should be made to narrow the digital divide in rural areas and promote digital health education. Pre-interventions on multidimensional health poverty can provide new pathways for the development, empowerment, and well-being of rural women of childbearing age.

The size-dependent in vivo toxicity of amorphous silica nanoparticles: A systematic review.

The extensive application of amorphous silica nanoparticles (aSiNPs) in recent years has resulted in unavoidable human exposure in daily life, thus raising widespread concerns regarding the safety of aSiNPs on human health. The particle size is one of the important characteristics of nanomaterials that could influence their toxicity. For the reason that particles with smaller sizes possess larger surface area, which may lead to higher surface activity and biological reactivity. However, due to the complexity of experimental conditions and biological systems, the relationship between the particle size and the toxic effect of aSiNPs remains unclear. Therefore, this systematic review aims to investigate how particle size influences the toxic effect of aSiNPs in vivo and to analyze the relevant experimental factors affecting the size-dependent toxicity of aSiNPs in vivo. We found that 83.8% of 35 papers included in the present review came to the conclusion that smaller-sized aSiNPs exhibited stronger toxicity, though a few papers (6 papers) put forward different opinions. The reasons for smaller aSiNPs manifested greater toxicity were summarized. In addition, certain important experimental factors could influence the size-dependent effects and in vivo toxicity of aSiNPs, such as the synthesis method of aSiNPs, disperse medium of aSiNPs, administration route of aSiNPs, species or strain of experimental animals, sex of experimental animals, aggregation/agglomeration and protein corona of aSiNPs.

Influencing factors of inter-nursing lateral violence: A qualitative systematic review.

BACKGROUND: Lateral violence is a global social problem that has attracted considerable attention in the field of public health. This has seriously affected the quality of care, the safety of patients' lives and the career development of nurses. OBJECTIVE: To systematically evaluate the factors influencing of nursing lateral violence and provide evidence for preventing and reducing inter-nursing lateral violence. METHODS: A systematic review of qualitative study was performed in accordance with the Enhancing Transparency in Reporting the Synthesis of Qualitative Research (ENTREQ) guidelines. We collected qualitative studies on the factors influencing of inter-nursing lateral violence by searching PubMed, EMbase, The Cochrane Library, Web of Science, CINAHL, Science Direct, WanFang Data, China National Knowledge Infrastructure (CNKI), Chinese Scientific Journal Database (VIP) and Chinese Biomedical Literature Database (CBM). Data from inception to September 2023. Literature screening and data extraction were independently conducted by two reviewers. The Critical Appraisal Skills Program (CASP) scale was employed to assess the quality of the studies, including objectives, methodologies, designs, results and contributions. RESULTS: A total of 25 studies involving 882 participants were included. The results of the thematic analysis indicated that inter-nursing lateral violence was influenced by hospital management, perpetrators, victims and sociodemographic factors. CONCLUSION: Inter-nursing lateral violence was influenced by multidimensional factors. To reduce the occurrence of horizontal violence among nurses, hospitals need to explore the establishment and improvement of a horizontal violence resolution mechanism, and schools should pay attention to the joint support and education of nursing students, create a good working environment and harmonious nursing culture, and promote mutual respect among nurses. RELEVANCE TO CLINICAL PRACTICE: This review emphasises the importance of the influencing factors of horizontal violence among nurses, analyses the importance of influencing factors from different perspectives, and proposes corresponding measures to reduce inter-nursing lateral violence. NO PATIENT OR PUBLIC CONTRIBUTION: This study was mostly a literature review; neither patients nor pertinent staff were involved in either the design or conduct of the investigation.

Revealing spatiotemporal heterogeneity of water conservation and its drivers: Enlightenment to water ecology protection and restoration.

Water conservation (WC) has emerged as one of the most vital services provided by basin ecosystems. Climate change, the conversion of farmland to forests, and the implementation of check dam projects significantly impact the WC function in the Malian River Basin (MRB) of the gully region, Loess Plateau. This study systematically and comprehensively reveals the variation rules of WC and the mechanisms of action of influence factors in the MRB and selects factors representing natural environmental changes and human activities, such as climate, geomorphology, vegetation, and soil, influencing the WC. The InVEST model and a modified formula were used to evaluate the WC and its spatial-temporal changes in the MRB. The response of influence factors to the WC was explored using a "geographical detection - spatial drive/inhibition - influence degree" framework. The results indicate that under the comprehensive influence of multiple factors, the spatial distribution of WC in the MRB remained relatively consistent over different periods, characterized by higher values in the southeast and lower in the northwest. The WC values in 1990, 2000, 2010, and 2020 were 2.57 × 104, 1.48 × 104, 2.19 × 104, and 1.93 × 104 m3, respectively. The interaction of two factors on WC had a more significant effect than single-factor interactions, particularly the interaction between Soil Saturated Water Conductivity (Ksat) and Annual Precipitation (Pre), Annual Evapotranspiration (AET), and Net Primary Productivity (NPP). Pre, Plant Available Water Content (PAWC), and Ksat are key positive drivers, while AET, Temperature (Temp), and Elevation (DEM) are crucial negative drivers. Climate factors had the largest explanatory power for the WC spatial pattern (34.03-36.54%), geomorphic factors had the least (16.60-17.50%), and vegetation factors more than soil factors. This study provides valuable insights for optimal water resource allocation and sustainable development of the gully region, Loess Plateau.

Unveiling the NIMBY effect in construction and demolition waste landfilling: Factors, paths, and solutions.

The construction and operation of the construction and demolition waste (C&DW) landfills often encounter significant opposition from nearby residents, which is called the "not in my backyard" (NIMBY) effect. However, little is known about the formation mechanism of the NIMBY effect in C&DW landfilling, so this research was conducted for this purpose. First, the influencing factors leading to the NIMBY effect were determined based on a literature review and questionnaire survey. Then, the interrelationship and influencing path of critical factors were revealed using expert interviews and Interpretative Structural Modelling. The results shown that 12 factors from four levels (including residents, society, government, and enterprises) caused the NIMBY effect in C&DW landfilling. These factors formed a complex network comprising 18 influencing paths. Notably, policy and responding measures as pivotal bottom-level factors that trigger the NIMBY effect by indirectly impacting residents' rights awareness and shaping public perception towards C&DW landfill operation enterprises through directly affecting personal interest, cognitive bias, distrust, disposal technology, management level, opinion leader, and other intermediate factors, ultimately triggering the NIMBY effect. Moreover, strategies for mitigating or resolving the NIMBY effect were proposed, such as protecting personal reasonable interests, understanding the potential risks of C&DW landfills rationally, reporting the C&DW landfills from an objective perspective, improving policies and promoting public participation, and enhancing supervision of the C&DW landfills. The study added new knowledge to the current public's NIMBY effect in C&DW landfilling. Meanwhile, it also provided a reference for formulating C&DW landfilling policies and selecting landfill sites.

Home care practice behavior and its influencing factors of primary care providers: a multicenter cross-sectional study in Sichuan Province, China.

BACKGROUND: Primary care providers play an important role in home health care, and their practice behavior is significant for care quality and patient outcomes. This study aimed to assess the home care practice behavior of Chinese primary care providers and to explore the factors associated with the practice behavior. METHODS: A multicenter cross-sectional design with a convenience sample was used to survey 863 registered primary care providers from 62 primary health care settings in Sichuan Province, China. Descriptive statistics, t-test or ANOVA for one-way analysis, and Pearson's correlation analyses were used to compare the differences and examine the relationships between participants' demographics and experience of home care services and practice behavior. Multiple linear regression models were performed to identify salient variables associated with the practice behavior from among demographic and home care experience. RESULTS: The score of home care practice behavior questionnaire was 97.25 ± 21.05. The average scores for the dimensions of home visit preparation, assessment, medical care behavior and safety practice were 3.70 ± 0.95, 3.76 ± 1.02, 3.66 ± 1.03, and 3.20 ± 0.46, respectively. Home care practice behavior was associated with working years, working experience in general hospitals, work area, home care experience such as client types of home care, service frequency and willingness, explaining 21.5% of the total variance. CONCLUSION: Chinese primary care providers had a medium to high level of home care practice behavior but poor implementation of safety practice. The results may provide clues to increased focus and implementation of safety practice, as well as providing targeted measures based on influencing factors.

Microplastics in Chinese coastal waters: A mini-review of occurrence characteristics, sources and driving mechanisms.

The oceans are facing global and irreversible pollution from microplastics, and China is not immune. In this mini-review, information on microplastics in four coastal waters of China and the natural and social environment of key basins were compiled. The results showed that microplastics were ubiquitous in the coastal waters, and the abundance and spatial distribution of microplastics varied significantly under different sampling methods. For trawl samples, microplastic abundance ranged from 0.045 to 1170.8 items m-3, among which the coastal waters of the East China Sea were the most polluted. For filtered samples, microplastic abundance ranged from 46 to 63,600 items m-3, and the coastal waters of the Yellow Sea were the most polluted. Meanwhile, human activities in basin were the key factors affecting microplastic pollution in coastal waters. The main terrestrial source in the coastal waters of the South China Sea was express packaging loss, whereas the main source in the other coastal waters was tyres and road markings wear from vehicle trip. The decoupling results of analytic hierarchy process showed that there was spatial heterogeneity in the impact of socio-economic and natural environmental factors in the basin on the distribution of microplastics in coastal waters. Among the five major basins, the impact weights of the latter were 20.00%, 83.34%, 66.66%, 50.00% and 25.00%, respectively. This study provides the first perspective of land-sea linkage to summarize the characteristics, sources and influencing factors of microplastics in Chinese coastal waters, providing ideas for reducing marine microplastic pollution from the source.

[Relationship between dietary nutrition and chronic disease of Jinuo Minority residents aged 20-80 in Jinghong District in 2020].

OBJECTIVE: To analyze the relationship between food intake and chronic diseases of Jinuo Minority residents living in Yunnan Province. METHODS: A total of 392 Jinuo Minority residents 20-80-year-old among 304 families(male 135, female 257; aged 20-49 years old 140, aged 50-59 years old 136, aged 60-80 years old 116)in Jinghong District in Yunnan Province were selected with stratified multistage cluster sampling method. To apply the method of food frequency questionnaire and questionnaire survey obtain the condition of dietary structure and overweight or obesity, diabetes and dyslipidemia among Jinuo Minority in the past 12 months. Non-conditional Logistic regression analysis was utilized to analyze the correlation between food intake and chronic diseases. RESULTS: In 2020, the prevalence of overweight/obesity, hypertension, diabetes and dyslipidemias among Jinuo adults in Jinghong District were 38.8%(n=152), 19.1%(n=75), 3.6%(n=14)and 26.3%(n=103). Jinuo residents aged 20 and above who have consumed noodle and instant noodle(OR=1.677, 95%CI 1.028-2.736), fermented soybean curd(OR=3.056, 95%CI 1.853-5.038), grass carp(OR=2.245, 95%CI 1.270-3.971), ethnic food/peanut(OR=1.975, 95%CI 1.162-3.355) were more likely to experience overweight/obesity compared to those who did not consume them. On the other hand, individuals who consumed snacks/bread(OR=0.322, 95%CI 0.190-0.545) were less likely to develop overweight/obesity compared to those who did not consume them. Jinuo residents aged 20 and above who have consumed other cereals and cereals products, such as buckwheat(OR=7.029, 95%CI 1.494-33.070), were more likely to develop diabetes than those who did not consume them. And those who have eaten cabbage vegetables(such as cauliflower/cabbage)(OR=0.155, 95%CI 0.034-0.708), and kernel fruits(such as apple/pear)(OR=0.227, 95% CI 0.069-0.743) were less likely to develop diabetes than those who did not consume them. Adults who consumed cooked meat and other livestock and poultry, such as donkey/horse meat(OR=9.676, 95% CI 1.418-66.027), were more likely to cause dyslipidemias compared to did not consume them. Conversely, individuals who consumed root vegetables(such as radish/lotus root)(OR=0.405, 95%CI 0.204-0.803), cooked pork from animal foods(OR=0.482, 95%CI 0.263-0.885), snacks/snack bread(OR=0.590, 95%CI 0.357-0.974) and plum blossom(OR=0.173, 95%CI 0.038-0.793) were less likely to develop dyslipidemia than those who did not consume them. CONCLUSION: In Jinghong District, the overweight/obesity of Jinuo adults aged 20-80 was positively correlated to the consumption of noodles and instant noodles, fermented bean curd, grass carp, and ethnic food/peanut. And there was a negative correlation with the consumption of snacks/bread. Regarding diabetes, a positive correlation was observed with the consumption of other grains and products, while negative correlations were found with the consumption of cabbage vegetables and kernel fruits. For dyslipidemias, there was a positive correlation with the consumption of cooked meat and other livestock and poultry, and negative correlations were identified with the consumption of root vegetables, cooked pork from animal foods, snacks/snack bread, and prunes.

The influence of preoperative urodynamic parameters on clinical results in patients with benign prostatic hyperplasia after transurethral resection of the prostate.

PURPOSE: To identify the urodynamic parameters affecting the clinical outcomes of transurethral resection of the prostate(TURP) surgery for patients with benign prostatic hyperplasia(BPH) by multifactor analysis and establish a regression model with diagnostic values. METHODS: The medical records of patients who underwent TURP surgery for BPH between December 2018 and September 2021 were collected from the urology department of the Second Affiliated Hospital of Kunming Medical University, Kunming, China. The patients' clinical data and urodynamic parameters were collected before surgery. The urodynamic parameters affecting surgical efficacy were identified by multifactor analysis, and a regression model with diagnostic values was established and evaluated. RESULTS: A total of 201 patients underwent TURP, of whom 144 had complete preoperative urodynamic data. Each urodynamic factor was subjected to multifactor analysis, and the bladder contractility index (BCI), bladder outflow obstruction index (BOOI), bladder residual urine, and bladder compliance (BC) were found to be independent influence factors on the efficacy of TURP in patients with BPH. The diagnostic value of the regression model was analyzed by receiver operating characteristics (ROC) analysis, and it was found that the AUC = 0.939 (95% CI 0.886-0.972), for which the sensitivity and specificity were 95.19% and 80%, respectively. CONCLUSIONS: The regression model had high diagnostic sensitivity and specificity in predicting the efficacy of surgery, and the diagnostic value was higher than that of individual urodynamic factors. Therefore, BCI, BOOI, bladder residual urine, and BC should be considered as independent influence factors on the efficacy of TURP surgery for BPH.

Volatile compounds and aroma characteristics of mushrooms: a review.

Mushrooms are popular due to their rich medicinal and nutritional value. Of the many characteristics of mushrooms, aroma has received extensive attention and research as a key determinant of consumer preference. This paper reviews the production, role and contribution of common volatile compounds (VCs) in wild and cultivated mushrooms, and explores the methods used to characterize them and the factors influencing aroma. To date, more than 347 common VCs have been identified in mushrooms, such as aldehydes, ketones, alcohols and sulfur-containing compounds. Extraction and identification of VCs is a critical step and combining multiple analytical methods is an effective strategy in mushroom aroma studies. In addition, the VCs and the aroma of mushrooms are affected by a variety of factors such as genetics, growing conditions, and processing methods. However, the mechanism of influence is unknown. Further studies on the production mechanisms of VCs, their contribution to aroma, and the factors influencing their formation need to be determined in order to fully elucidate aroma and flavor of mushrooms.

Identification and Parametrization of Key Factors Affecting Levoglucosan Emission During Solid Fuel Burning.

Levoglucosan (LG) is a pyrolysis product of cellulose and hemicellulose at low combustion temperatures. However, LG release cannot be determined only by considering the contents of cellulose and hemicellulose exclusively due to the complexity of combustion processes and the physical-chemical properties of the fuel. This study detected the emission factors (EFs) of LG from 22 different solid fuel samples (including coal and biomass) by considering 18 different fuel properties and five combustion parameters. The average LGEFs during solid fuel burning varied in a range of 0.03-136 mg kg-1, with a magnitude difference of 1-4 orders. While the variations in cellulose (59.5-368 mg g-1) and hemicellulose (73.5-165 mg g-1) contents of fuel samples were only one- to 6-fold. A short combustion duration (<150 min) and a medium combustion temperature (200-400 °C) influenced by volatile and ash contents are crucial for the generation and accumulation of LG. A random forest coupled with the Akaike information criterion stepwise regression model successfully explained 96% of the total LG emission variation using three variables (ash content, cellulose content, and modified combustion efficiency). The ash content promoted coke formation and LG chain cracking by increasing the pyrolysis temperature and is considered the most important factor. The alkali metal in ash can reduce the energy barrier of intramolecular ring contraction reactions and inhibit the dehydration reactions, which led to additional heat being utilized by the competitive pathways of LG formation. This study provided a method to address the parametrization and release mechanisms of combustion source emissions.

Construction of Prognostic Nomogram in Patients with N3-Stage Nasopharyngeal Carcinoma.

INTRODUCTION: The aim of the study was to retrospectively identify the metastatic influence factors and predict the prognosis and develop an individualized prognostic prediction model for patients with N3-stage nasopharyngeal carcinoma (NPC). METHODS: The study collected 446 NPC patients with N3 stage from the Surveillance, Epidemiology, and End Results database between 2010 and 2015. The patients were classified into subgroups based on the histological types and metastatic status. Multivariable logistic, Cox regression, and Kaplan-Meier method with the log-rank test were performed. The nomogram model was created using the prognostic factors identified from Cox regression analysis. The predictive accuracy was determined based on the concordance index (c-index) and calibration curves. RESULTS: The 5-year overall survival (OS) of the NPC patients with N3 stage was 43.9%, and the prognosis of patients without any distant metastases was largely longer than that with metastases. No difference was observed between different pathological types in the entire cohort. However, patients with non-keratinized squamous cell carcinoma had a better OS than that of the patients with keratinized squamous cell carcinoma in a nonmetastatic subgroup. Using the Cox regression analysis results, the nomogram successfully classified these patients into low- and high-risk subgroups and presented the survival difference. The c-index of the nomogram for predicting the prognosis was satisfactory. CONCLUSION: This study identified metastatic risk factors and developed a convenient clinical tool for the prognosis of NPC patients. This tool can be used for individualized risk classification and decision-making regarding treatment of NPC patients with N3 stage.

Bitter Peptides in Fermented Soybean Foods - A Review.

Fermented soybean foods with a long history are popular worldwide because of rich nutrition. However, many traditional fermented soybean foods have unacceptable bitterness, which mostly comes from the bitter peptides produced from the hydrolysis of soybean proteins. In this review, the bitter peptides in fermented soybean foods is briefly reviewed. The structural properties of bitter receptors and bitter peptides were reviewed. Bitterness is perceived through the binding between bitter compounds and specific sites of bitter receptors (25 hTAS2Rs), which further activate the downstream signal pathway mediated by G-protein. And it converts chemical signals into electrical signals, and transmit them to the brain. In addition, the influencing factors of bitter peptides in fermented soybean foods were summarized. The bitterness of fermented soybean foods primarily results from the raw materials, microbial metabolism during fermentation, unique techniques, and interactions of various flavor compounds. Moreover, the structure-bitterness relationship of bitter peptides was also discussed in this review. The bitterness degree of the bitter peptide is related to the polypeptide hydrophobicity, amino acids in the peptide, peptide molecular weight and polypeptide spatial structure. Studying the bitter peptides and their bitter characteristics in fermented soybean foods is beneficial for improving the sensory quality of fermented soybean foods and prompting more consumers accept them.

Associated factors of health-promoting lifestyle of the elderly based on the theory of social ecosystem.

OBJECT: To explore the factors related to health-promoting lifestyles of the elderly based on social-ecosystem theory. DESIGN: A cross-sectional survey study was carried out to include 627 elderly people in communities in three cities of Hebei Province (Shijiazhuang, Tangshan, and Zhangjiakou) from October 2021 to January 2022 for questionnaire survey (601 validly returned cases). VENUE: Three cities of Hebei Province (Shijiazhuang, Tangshan, and Zhangjiakou). PARTICIPANTS: 627 elderly people. INTERVENTIONS: A cross-sectional survey study. MAIN MEASUREMENTS: The questionnaire survey was conducted by using the general demographic data, health promotion life scale, frailty scale, general self-efficacy scale, health engagement scale, General Self-Efficacy Scale, The family Adaptability, Partnership, Growth, Affection, and Resolve scale, and Perceived Social Support Scale. RESULTS: The total health promotion lifestyle score for the elderly was 100.20±16.21, which was at the lower limit of the good level, with the highest mean score for nutrition (2.71±0.51) and the lowest mean score for physical activity (2.25±0.56). Stepwise linear regression showed that exercise frequency (95% confidence interval (CI) 1.304-3.885), smoking status (95% CI -4.190 to -1.556), self-efficacy (95% CI 0.071-0.185), health management (95% CI 0.306-0.590), frailty (95% CI -3.327 to -1.162) in the microsystem, marital status (95% CI 0.677-3.660), children's attention to the elderly health (95% CI 4.866-11.305), family care in the mesosystem (95% CI 1.365-4.968), and pre-retirement occupation (95% CI 2.065-3.894), living area (95% CI 0.813-3.912), whether receive community-based chronic disease prevention and management services (95% CI 2.035-8.149), social support (95% CI 1.667-6.493) in the macrosystem were the main factors affecting health promotion of life in the elderly (P<0.05). Hierarchical regression analysis showed the microsystem accounted for 17.2%, the mesosystem accounted for 7.1%, and the macrosystem accounted for 11.4%. CONCLUSION: The health promotion lifestyle of the elderly in Hebei Province was at the lower limit of good level. Among them, exercise frequency, children's attention to the elderly health, and pre-retirement occupation played a major role in relation to the health-promoting lifestyle of the elderly. Hence, it needs the joint action of individuals, families, and society to promote the elderly to adopt the health promotion lifestyle and realize healthy aging.

[Survey on the awareness rate of nutrition and health knowledge among residents aged 18-64 in Shanghai in 2021].

OBJECTIVE: To analyze the nutrition and health knowledge of residents aged 18-64 in Shanghai, and to understand the level of nutrition and health knowledge and its influencing factors. METHODS: The total of 6518 residents aged 18-64 years old in Shanghai were selected by stratified random sampling in 2021. The subjects were grouped by gender, age, education levels, occupations, and regions. The awareness rate of nutrition and health knowledge and its influencing factors were investigated using the questionnaire and scoring standard designed by National Institute for Nutrition and Health, Chinese Center for Disease Control and Prevention. Household survey, face-to-face questioning by surveyors and help to fill in the options. RESULTS: The score of nutrition and health knowledge of residents aged 18-64 in Shanghai was 68.43±12.82, and the awareness rate was 35.78%. The average score(t=-5.04, P<0.01) and awareness rate(χ~2=14.06, P<0.01) of women were significantly higher than men. Significant differences in average scores and awareness rates were found among different groups of ages(F=15.02, P<0.01;χ~2=23.46, P<0.01), education levels(F=191.45, P<0.01;χ~2=210.29, P<0.01), occupations(F=99.17, P<0.01;χ~2=224.12, P<0.01) and regions(F=22.11, P<0.01;χ~2=44.61, P<0.01). The female(OR=1.13, 95%CI 1.02-1.25), high school education and above(OR=1.68-2.85) had better knowledge of nutrition and health. While 18-34 years(OR=0.69-0.74), people engaged in non-medical health institutions(OR=0.46-0.70) and living in non-urban central areas(OR=0.74-0.81) had poorer awareness of nutrition and health knowledge. CONCLUSION: The awareness rate of nutrition and health knowledge among residents aged 18-64 in Shanghai is still upside potential.

The fate of antibiotic resistance genes in the coastal lagoon with multiple functional zones.

Coastal lagoons provide many important services to human society, but their year-round use for aquaculture introduces large amounts of sewage. The contamination of antibiotic resistance genes (ARGs) is therefore of great concern. In this study, 50 ARGs subtypes, two integrase genes (intl1, intl2), and 16S rRNA genes were detected by high-throughput quantitative PCR, and standard curves of all target genes were prepared for quantification. The occurrence and distribution of ARGs in a typical coastal lagoon (XinCun lagoon, China) were comprehensively explored. We detected 44 and 38 subtypes of ARGs in the water and sediment, respectively, and discuss the various factors influencing the fate of ARGs in the coastal lagoon. Macrolides-lincosamides-streptogramins B was the primary ARG type, and macB was the predominant subtype. Antibiotic efflux and antibiotic inactivation were the main ARG resistance mechanisms. The XinCun lagoon was divided into eight functional zones. The ARGs showed a distinct spatial distribution owing to the influence of microbial biomass and anthropogenic activity in different functional zones. Fishing rafts, abandoned fish ponds, the town sewage zone, and mangrove wetlands provided a large quantity of ARGs to the XinCun lagoon. Nutrients and heavy metals also significantly correlated with the fate of the ARGs, especially NO2--N and Cu, which cannot be ignored. It is noteworthy that lagoon-barrier systems coupled with persistent pollutant inputs result in coastal lagoons acting as a "buffer pool" for ARGs, which can then accumulate and threaten the offshore environment.

[Study on risk factors of abnormal pulmonary function among dust-exposed workers and prediction model].

Objective: To explore the influencing factors of abnormal pulmonary function in dust-exposed workers and establish the risk prediction model of abnormal pulmonary function. Methods: In April 2021, a total of 4255 dust exposed workers from 47 enterprises in 2020 were included in the study. logistic regression was used to analyze the influencing factors of abnormal pulmonary function in dust-exposed workers, and the corresponding nomogram prediction model was established. The model was evaluated by ROC curve, Calibrationpolt and decision analysis curve. Results: logistic regression analysis showed that age (OR=1.03, 95%CI=1.02~1.05, P<0.001) , physical examination type (OR=4.52, 95%CI=1.69~12.10, P=0.003) , dust type (Comparison with coal dust, Cement dust, OR=3.45, 95%CI=1.45~8.18, P=0.005, Silica dust (OR=2.25, 95%CI=1.01~5.03, P=0.049) , blood pressure (OR=1.63, 95%CI=1.22~2.18, P=0.001) , creatinine (OR=0.08, 95%CI=0.05~0.12, P<0.001) , daily exposure time (OR=1.06, 95%CI=1.10~1.12, P=0.034) and total dust concentration (OR=1.29, 95%CI=1.08~1.54, P=0.005) were the influencing factors of abnormal pulmonary function. The area under the ROC curve of risk prediction nomogram model was 0.764. The results of decision analysis curve showed that the nomogram model had reference value in the prevention and intervention of abnormal pulmonary function when the threshold probability exceeded 0.05. Conclusion: The accuracy ofthe nomogram model constructed by logistic regression werewell in predicting the risk of abnormal lung function of dust-exposed workers.
