Abstract Background Evidence on the association between the non-high-density lipoprotein cholesterol (non-HDLc)-to-high-density lipoprotein cholesterol (HDLc) ratio (non-HDLc/HDLc) and carotid plaques is still limited. We aimed to assess the relationship between the non-HDLc/HDLc and carotid plaques in a population with a high risk of stroke. Methods A cross-sectional study based on the community was conducted in Yangzhou, China. Residents (no younger than 40 years old) underwent questionnaire interviews, physical examinations, and laboratory testing during 2013–2014. The subjects with a high risk of stroke were further selected (at least three of eight risk factors including hypertension, atrial fibrillation, type 2 diabetes mellitus, dyslipidaemia, smoking, lack of exercise, overweight, and family history of stroke) or a transient ischaemic attack (TIA) or stroke history. Carotid ultrasonography was then performed on the high stroke risk participants. Logistic regression was employed to evaluate the relationship between the non-HDLc/HDLc and carotid plaques. Results Overall, 839 subjects with a high risk of stroke were ultimately included in the analysis, and carotid plaques were identified in 341 (40.6%) of them. Participants in the highest non-HDLc/HDLc tertile group presented a higher proportion of carotid plaques than did those in the other two groups. After adjustment for other confounders, each unit increase in the non-HDLc/HDLc was significantly associated with carotid plaques (OR 1.55, 95%CI 1.28–1.88). In the subgroup analysis, the non-HDLc/HDLc was positively and significantly associated with the presence of carotid plaques in most subgroups. Additionally, the non-HDLc/HDLc interacted significantly with three stratification variables, including sex (OR 1.31 for males versus OR 2.37 for females, P interaction = 0.016), exercise (OR 1.18 for subjects without lack of exercise versus OR 1.99 for subjects with lack of exercise, P interaction = 0.004) and heart diseases (OR 1.40 for subjects without heart diseases versus OR 3.12 for subjects with heart diseases, P interaction = 0.033). Conclusion The non-HDLc/HDLc was positively and consistently associated with the presence of carotid plaques in a Chinese high stroke risk population.

The subjects with a high risk of stroke were further selected (at least three of eight risk factors including hypertension, atrial fibrillation, type 2 diabetes mellitus, dyslipidaemia, smoking, lack of exercise, overweight, and family history of stroke) or a transient ischaemic attack (TIA) or stroke history. Carotid ultrasonography was then performed on the high stroke risk participants. Carotid plaque was defined as a focal carotid intima-media thickness (cIMT) ≥1.5 cm or a discrete structure protruding into the arterial lumen at least 50% of the surrounding cIMT. Logistic regression was employed to evaluate the relationship between the non-HDLc/HDLc and carotid plaques.Results: Overall, 839 subjects with a high risk of stroke were ultimately included in the analysis, and carotid plaques were identified in 341 (40.6%) of them. Participants in the highest non-HDLc/HDLc tertile group presented a higher proportion of carotid plaques than did those in the other two groups.

Conclusion: The non-HDLc/HDLc was positively associated with the presence of carotid plaques in a Chinese high stroke risk population. A prospective study or randomized clinical trial of lipid-lowering therapy in the Chinese population is needed to evaluate their causal relationship.

Background: Cardiometabolic index (CMI) is associated with several risk factors for stroke; however, few studies have assessed the role of CMI in stroke risk. Objective: This study aimed to assess the association between CMI and stroke in a population-based cross-sectional study. Methods: This study included 4445 general residents aged ≥40 years selected by multistage stratified random cluster sampling. CMI was calculated as the product of the ratio of waist circumference to height (WHtR) and the ratio of triglyceride levels to high-density lipoprotein cholesterol levels (TG/HDL-C). Participants were categorized according to CMI quartiles: quartile 1 (Q1), quartile 2 (Q2), quartile 3 (Q3), and quartile 4 (Q4). Multivariate logistic regression analysis and receiver operating characteristic (ROC) curves were used to assess the association between CMI and stroke. Results: A total of 4052 participants were included in the study, with an overall stroke prevalence of 7.2%. The prevalence of stroke increased with CMI quartiles, ranging from 4.4% to 9.2% (p for trend <0.001). Compared with Q1, stroke risk for Q2, Q3, and Q4 were 1.550-, 1.693-, and 1.704- fold, respectively. The area under the ROC curve (AUC) [95% CI] was (0.574 [0.558−0.589]) for CMI, 0.627 [0.612−0.642]) (p=0.0024) for WHtR, 0.556 [0.540−0.571]) (p<0.0001) for TG/HDL-C. CMI was inferior to WHtR, but CMI had marginal advantage over TG/HDL-C in terms of its stroke discrimination ability. Conclusion: Although there was a strong and independent association between CMI and stroke in the general population, CMI had limited discriminating ability for stroke. Thus, new parameters should be developed.

Ship sanitation is an indicator of vessel cleanliness, vector control in 2017 no high-risk vessels were found, in 2018 there were 7 high-risk vessels and in 2019 there were 15 high-risk vessels. This study aims to determine the relationship between kitchen sanitation, food raft space and warehouse with cockroach density on ships in the Kendari port area. This type of research is an observational, Cross-Sectional Study design. The population is all ships berthed in the Kendari port area as many as 41 ships and a sample of 37 vessels taken by purposive sampling. Data analysis used fisher's exact test. The results showed that of the 37 ships, the highest density of cockroaches met the requirements (75.7%), the rest did not meet the requirements (24.3%). The kitchen sanitation met the requirements (75.7%), the rest did not meet the requirements (24.3%), then the food raft room sanitation met the requirements (83.8%) and did not meet the requirements (16.2%). Furthermore, warehouse sanitation fulfills the requirements (62.2%) and does not meet the requirements (37.8%). The results of Fisher's exact test obtained p value (0,000). The conclusion of this study is that there is a relationship between kitchen sanitation, food raft space and warehouse with cockroach density on ships in the Kendari port area. Suggestions for the KKP to establish policies to prevent cockroach development.

Abstract Background Stroke is a leading cause of mortality and disability worldwide. Most stroke risk studies focused on more established biological and pathophysiological risk factors such as hypertension and smoking, psychosocial factors such as quality of life are often under-investigated and thus less reported. The current study aims to estimate stroke risk and explore the impact of quality of life on stroke risk among a community sample of urban residents in Shanghai. Methods This cross-sectional study was conducted in Fengxian District of Shanghai City from December 2018 to April 2019. 4030 representative participants were recruited through a multistage, stratified, probability proportional to size sampling method and completed the study. Stroke risk was assessed using the Rapid Stroke Risk Screening Chart that included 8 risk factors for stroke. Quality of life was measured using the World Health Organization Quality of Life-brief version (WHOQOL-BREF). Results One-third of residents were at risk for stroke, including 14.39% at high risk, and 18.68% at middle risk. The top three most commonly reported risk factors were physical inactivity (37.30%), hypertension (25.38%), and smoking (17.32%). Quality of life and its four domains were all independently and significantly associated with stroke risk. Multinominal logistic regressions showed that a one-unit increase in the quality of life was associated with a decreased relative risk for middle-risk relative to low-risk of stroke by a factor of 0.988 (95% CI:0.979, 0.997, P = 0.007), and a decreased relative risk for high-risk relative to low-risk of stroke by a factor of 0.975 (95% CI:0.966, 0.984, P < 0.001). Conclusions Our findings showed an alarmingly high prevalence of stroke risk among the sample, which may require future intervention programs to focus on improving both biological and behavioral risk factors such as increasing physical activity, early diagnosis and treatment of hypertension, and smoking cessation, as well as improving psychosocial factors such as quality of life.

Abstract Background Evidence regarding the relationship between normal low-density lipoprotein cholesterol (LDL-c) levels and non-alcoholic fatty liver disease (NAFLD) was limited. Therefore, this dissertation seeks to investigate the relationship between LDL-c and NAFLD in the non-obese Chinese population after adjusting for other covariates. Methods The present study was a cross-sectional study. A total of 183903 non-obese participants were involved in a Wenzhou Medical Center of Wenzhou People’s Hospital from 2010 to 2014. The target independent variable and the dependent variable were LDL-c measured at baseline and NAFLD respectively. Covariates involved in this study included SEX, AGE, BMI, SBP, DBP, FPG, ALB, ALT, AST, BUN, Cr, TG, TC, HDL-c, UA. It was noted that the entire study was completed by Dan-Qin Sun et al., and uploaded the data to the DATADRYAD website. The author only used this data for secondary analysis. Results The average age of 183903 selected participants was 41.0 ± 14.1 years old,and about 49.6% of them was male. After adjusting potential confounders (SEX, AGE, BMI, FPG, ALB, GLB, ALT, AST, GGT, BUN, Cr, TG, TC, HDL-c, UA), non-linear relationship was detected between normal LDL-c levels and NAFLD, whose point was 1.51. The effect sizes and the confidence intervals on the left and right sides of inflection point were 0.87 (0.64, 1.18) and 1.79 (1.67, 1.92), respectively. Conclusion The relationship between normal LDL-c levels and NAFLD is non-linear. Normal LDL-c levels was positively correlated with NAFLD when LDL-c was more than 1.51.

Abstract Background Some previous studies have reported that the ratio of triglycerides to high-density lipoprotein may indicate insulin resistance, but the results suggest that there are differences between different ethnic groups. In this study, the NHANES 2017-2018 database was used to explore the relationship between TG/HDL-C and IR in the American population. Methods This trial comes from a cross-sectional study of NHANES ( http://www.cdc.gov/nchs/nhanes/ ) conducted by the National Center for Health Statistics (NCHS) of the US Centers for Diseases and Control and Prevention. IR uses the homeostatic model assessment (HOMA) formula as an indicator: [fasting insulin (μU/mL)×fasting blood glucose (mmol/L)]/22.5, with ≥75th percentile of HOMA-IR as an indicator. Use logistic regression to explore the relationship between TG/HDL ratio and IR occurrence. Results In this study, a total of 450 participants (40%,450/1902) developed insulin resistance. Using logistic regression model of the association between TG/HDL-C and insulin resistance risk, after adjusting for potential confounding factors, as the TG/HDL ratio increases, the probability of insulin resistance increases significantly (OR: 1.91, 95% CI: 1.59-2.30, P<0.0001). At the same time, we performed a smooth curve fitting and found a non-linear relationship between TG/HDL and IR. Even if the adjusted covariate is deleted from the model, the association remains unchanged. The smooth curve of TG/HDL-C The inflexion point is 0.95. When TG/HDL-C<0.95, the effect value is very significant (OR: 27.34, 95%CI, 10.61-70.47, P<0.0001), when TG/HDL-C≥0.95, the effect value is relatively reduced (OR: 1.29, 95% CI, 1.03-1.61, P<0.0001). We grouped them by inflexion points. Multiple regression equations showed that after adjustment, the group's risk of insulin resistance greater than 0.95 increased by two times compared with the group less than 0.95. Conclusions In this study, we found that the increase of TG/HDL-C ratio in the American population was significantly related to IR. It is clinically acceptable and can save some extra costs for patients. However, in different situations, combining the TG/HDL-C ratio with other risk factors to predict whether IR will occur is worthwhile for the next step.
