The Naples prognostic score serves as a predictor and prognostic indicator for cancer survivors in the community.

OBJECTIVE: Inflammation, malnutrition, and cancer are intricately interconnected. Despite this, only a few studies have delved into the relationship between inflammatory malnutrition and the risk of death among cancer survivors. This study aimed to specifically investigate the association between the categorically defined Naples prognostic score (NPS) and the prognosis of cancer survivors. METHODS: Data from 42,582 participants in the National Health and Nutrition Examination Survey (NHANES, 1999-2018) were subjected to analysis. Naples prognostic scores (NPS) were computed based on serum albumin (ALB), total cholesterol (TC), neutrophil to lymphocyte ratio (NLR), and lymphocyte to monocyte ratio (LMR), and participants were stratified into three groups accordingly. Cancer status was ascertained through a self-administered questionnaire, while mortality data were sourced from the National Death Index up to December 31, 2019. Multiple logistic regression was employed to estimate the odds ratio (OR) with a 95% confidence interval (CI) between NPS and cancer prevalence within the U.S. community population. Kaplan-Meier survival analysis and the Log-rank test were utilized to compare survival disparities among the three groups. Additionally, Cox proportional regression was utilized to estimate the hazard ratio (HR) with a 95% CI. RESULTS: The incidence of cancers was 9.86%. Among the participants, 8140 individuals (19.1%) were classified into Group 0 (NPS 0), 29,433 participants (69.1%) into Group 1 (NPS 1 or 2), and 5009 participants (11.8%) into Group 2 (NPS 3 or 4). After adjusting for confounding factors, the cancer prevalence for the highest NPS score yielded an odds ratio (OR) of 1.64 (95% CI: 1.36, 1.97) (P(for trend) < 0.05). In comparison to cancer survivors in Group 0, those with the highest NPS had adjusted hazard ratios (HRs) of 2.57 (95% CI: 1.73, 3.84) for all-cause mortality, 3.44 (95% CI: 1.64, 7.21) for cardiovascular mortality, 1.60 (95% CI: 1.01, 2.56) for cancer mortality, and 3.15 (95% CI: 1.74, 5.69) for other causes of mortality (All P(for trend) < 0.05). These associations remained consistent when stratified by age, sex, race, and body mass index. CONCLUSIONS: This study indicates that the Naples prognostic score (NPS), serving as a novel prognostic metric integrating inflammation and nutritional status, is closely linked to cancer prognosis within the general population.

Inferring stability and persistence in the vaginal microbiome: A stochastic model of ecological dynamics.

The interplay of stochastic and ecological processes that govern the establishment and persistence of host-associated microbial communities is not well understood. Here we illustrate the conceptual and practical advantages of fitting stochastic population dynamics models to multi-species bacterial time series data. We show how the stability properties, fluctuation regimes and persistence probabilities of human vaginal microbial communities can be better understood by explicitly accommodating three sources of variability in ecological stochastic models of multi-species abundances: 1) stochastic biotic and abiotic forces, 2) ecological feedback and 3) sampling error. Rooting our modeling tool in stochastic population dynamics modeling theory was key to apply standardized measures of a community's reaction to environmental variation that ultimately depends on the nature and intensity of the intra-specific and inter-specific interaction strengths. Using estimates of model parameters, we developed a Risk Prediction Monitoring (RPM) tool that estimates temporal changes in persistence probabilities for any bacterial group of interest. This method mirrors approaches that are often used in conservation biology in which a measure of extinction risks is periodically updated with any change in a population or community. Additionally, we show how to use estimates of interaction strengths and persistence probabilities to formulate hypotheses regarding the molecular mechanisms and genetic composition that underpin different types of interactions. Instead of seeking a definition of "dysbiosis" we propose to translate concepts of theoretical ecology and conservation biology methods into practical approaches for the management of human-associated bacterial communities.

Comprehensive Insights into the Health Effects of Selenium Exposure and Supplementation Among the Chinese Community Middle-Aged and Elderly: a Combined Retrospective Cohort Study and Intervention Study.

Selenium (Se) is an essential trace element for maintaining human health, for example, plays a crucial role in preventing aging-related diseases. However, most studies on the health effects of Se among the community middle-aged and elderly have been observational or the health indices were single, and the related study among the Chinese population is limited. Additionally, China is recognized as among the countries facing a significant deficiency in Se, and Se contents in the human body may decrease with age. Therefore, a two-step study was conducted to explore the health effects of Se exposure and supplementation among such populations in China. Firstly, a retrospective cohort study was conducted to compare the health outcomes between such populations residing in Se-rich regions and non-Se-rich regions, involving a total of 102 subjects, with 51 residing in Se-rich regions and 51 in non-Se-rich regions. The hair-Se (H-Se) contents, serum-Se (S-Se) contents, and total cholesterol of subjects from Se-rich regions were significantly higher than their counterparts. Notably, significant positive associations were observed between S-Se and lipids. Secondly, a before-after self-control Se supplementation study among subjects residing in non-Se-rich regions was conducted. A total of 40 subjects administered Se tablets orally for 30 days, with Se of 120 µg/day. The results showed significant increases in H-Se and S-Se. Se supplementation also exhibited positive effects on alanine aminotransferase, homocysteine, and fasting glucose; however, high-density lipoprotein cholesterol significantly decreased. Overall, the community middle-aged and elderly residing in Se-rich regions or receiving quantitative Se supplementation could effectively improve Se contents in bodies and certain health indices, excluding lipids. These improvements encompass liver function, cardiovascular health, and glucose metabolism. These findings enhance our understanding of how Se impacts the health of the middle-aged and elderly, emphasizing the significance of targeted interventions for such populations in non-Se-rich regions.

Screening practices for obstructive sleep apnea in healthy community people: a Chinese community-based study.

Background: Owing to the lack of clear guidelines, the significance of obstructive sleep apnea (OSA) screening in healthy community people is unclear. This study aimed to screen for OSA in a healthy community population and provide a basis for its screening. Methods: Permanent residents from five communities in the coastal and mountainous areas of south China were selected. The screening process included demographic and sleep questionnaire surveys, and an OSA screening. To compare the prevalence and risk factors of OSA in different areas, a type IV wearable intelligent sleep monitor (WISM) was used for screening. Results: A total of 3,650 participants completed all studies, with a mean age of 53.81±12.71 years. In addition, 4,318 participants completed the OSA screening within 30 days, and the objective screening speed was 200 people per day. The recovery rate of the screening equipment was 99.37% (4,291/4,318), the screening success rate was 89.63% (3,846/4,291), and the rejection rate was 2.7% (120/4,438). The prevalence of high-risk OSA screened using the Stop-Bang questionnaire was 42.8% (1,563/3,650) and that screened using the device was 30.7% (1,119/3,650). The prevalence of OSA screened using the Stop-Bang questionnaire was higher than that screened using the device (P<0.01). Further analysis of sleep quality and daytime sleepiness showed that 47.6% (1,736/3,650) of the community population had good sleep quality and 6.6% (240/3,650) had daytime sleepiness. Age, sex, body mass index (BMI), neck circumference, and hypertension were risk factors for OSA in the community population. Conclusions: The use of objective type IV sleep detection equipment to screen a large sample population in the community in a short time is feasible. The prevalence of high-risk OSA screened using the Stop-Bang questionnaire was higher than that screened using the objective screening device.

Antibiotic Knowledge, Antibiotic Resistance Knowledge, and Antibiotic Use: A Cross-Sectional Study among Community Members of Bangkok in Thailand.

This study aimed to explore antibiotic knowledge, antibiotic resistance knowledge, and antibiotic use among adults in Bangkok, Thailand. This is a secondary analysis of cross-sectional data generated from a sample of 161 individuals living in Bangkok. Participants completed an online self-administered questionnaire developed by the World Health Organization. Descriptive analysis, the chi-square test, and multiple logistic regression analyses were performed. The sample comprised more females (56.5%) than males (42.2%). The majority of responders (67.7%) were between the ages of 18 and 40. More than half of the respondents mistakenly believed that antibiotics could treat colds and flu (54.7% and 47.2%, respectively). About 54.7% were aware that antibiotic resistance could harm them and their families. The chi-square test results showed that the levels of education were associated with antibiotic knowledge (p = 0.012), antibiotic resistance knowledge (p < 0.001), and antibiotic use (p = 0.023). Multiple logistic regressions showed that respondents with at least a bachelor's degree or higher had better knowledge of antibiotics. Respondents who worked in the profession had better knowledge of antibiotic resistance. Respondents with sufficient incomes were more likely to use antibiotics. Baseline data from the study will be useful in antibiotic stewardship and public health campaigns among Bangkok residents.

Associations between depression and the incident risk of obesity in southwest China: A community population prospective cohort study.

Objective: This study aimed to describe the incidence of obesity and investigate associations between depression and the risk of incident obesity among residents in Southwest China. Methods: A 10-year prospective cohort study of 4,745 non-obese adults was conducted in Guizhou, southwest China from 2010 to 2020. Depression was assessed by the Patient Health Questionnaire-9 (PHQ-9) while the obesity was identified by waist circumference (WC) and/or body mass index (BMI). Cox proportional hazard models were used to estimate hazard ratios (HR), and 95% confidence intervals (CIs) of depression and incident obesity. Results: A total of 1,115 incident obesity were identified over an average follow-up of 7.19 years, with an incidence of 32.66 per 1,000 PYs for any obesity, 31.14 per 1,000 PYs and 9.40 per 1,000 PYs for abdominal obesity and general obesity, respectively. After adjustment for potential confounding factors, risks of incident abdominal obesity for subjects with minimal (aHR: 1.22, 95% CI: 1.05, 1.43), and mild or more advanced depression (aHR: 1.27, 95% CI: 1.01, 1.62) were statistically higher than those not depressed, while there was no significant association with incident general obesity. The risks of any incident obesity among subjects with minimal (aHR: 1.21, 95% CI: 1.04, 1.40), mild or more advanced depression (aHR: 1.30, 95% CI: 1.03, 1.64) were significantly higher than those not depressed and positive association was found for PHQ score per SD increase (aHR: 1.07, 95%CI: 1.01, 1.13), too. The association was stronger significantly in Han Chinese (minimal: aHR: 1.27, 95% CI: 1.05, 1.52; mild or more advanced: aHR: 1.70, 95% CI: 1.30, 2.21) and farmers (minimal: aHR: 1.64, 95% CI: 1.35, 2.01; mild or more advanced: aHR: 1.82, 95% CI: 1.32, 2.51). Conclusion: Depression increased the risk of incident obesity among adults in Southwest China, especially among Han Chinese and farmers. This finding suggests that preventing and controlling depression may benefit the control of incident obesity.

Short night-time sleep duration is associated with thyroid nodules: A community-based survey from Guangzhou, China.

BACKGROUND: Sleep plays a critical role in maintaining human health. This study aimed to explore the association between sleep status and thyroid nodules. METHODS: A total of 2414 individuals aged 18 or older with euthyroidism were enrolled in this community-based survey. Sleep status was self-reported. Thyroid ultrasonography was performed to measure nodules. Multiple logistic analyses were applied to adjust for confounding factors. RESULTS: The percentages of thyroid nodules among individuals who slept <5 hours, 5-8 hours, and >8 hours per night were 57.79% (115/199), 44.19% (833/1885) and 42.73% (141/330), respectively (p = 0.001). Individuals who slept <5 hours per night had a significantly higher percentage of thyroid nodules than those who slept 5-8 hours per night (57.79% vs. 44.19%, p = 0.001) or >8 hours per night (57.79% vs. 42.73%, P < 0.001). However, no similar result was shown between individuals who slept >8 hours and 5-8 hours per night (42.73% vs. 44.19%, p = 0.621). Multiple logistic analysis showed that a sleep duration of <5 hours per night was significantly associated with thyroid nodules (odds ratio (OR) 1.643, 95% confidence interval (CI) 1.084-2.490, p = 0.019) when compared to a sleep duration of >8 hours per night. However, a sleep duration of <5 hours per night was not associated with thyroid nodules compared to a sleep duration of 5-8 hours (OR 1.294, 95% CI 0.918-1.824, p = 0.141). Similarly, no significant differences were seen among sleep duration per day, time of falling asleep, habit of daytime napping or thyroid nodules in multiple logistic analyses (all p > 0.05). CONCLUSIONS: Short nighttime sleep duration was associated with thyroid nodules in our community-based population. Screening for thyroid nodules among these individuals is recommended.

Association between depressive symptoms and risk of coronary heart disease in middle-aged and elderly Chinese community: An empirical analysis based on CHARLS database / 西安交通大学学报(医学版)

【Objective】 To investigate the association of depressive symptoms with the predicted risk of coronary heart disease in middle-aged and elderly Chinese based on a large community study. 【Methods】 A total of 2532 cases in the group without depression and 2758 cases in the group with depression were included. We compared the two groups in general demographics, information related to coronary heart disease risk, and physical function and ability to perform daily living. We also analyzed the factors associated with coronary heart disease risk by linear regression. 【Results】 ① Demographic information: The group with depression had a higher mean age, a higher proportion of women, more people with poor marital status, and a higher number of comorbid chronic diseases compared with the group without depression (all P<0.05). ② Risk indicators related to coronary heart disease: The group with depression had more people with diabetes and a significantly higher systolic blood pressure compared with the group without depression (P<0.05). The two groups did not significantly differ in the proportion of smokers, diastolic blood pressure, LDL-C, or HDL-C (all P>0.05). The risk of coronary heart disease was significantly higher in the group with depression than in the group without depression (P<0.05). ③ Physical function and ability of daily living: The physical function score, physical self-care score, and instrumental daily living ability were significantly higher in the group with depression than in the group without depression (all P<0.001). ④ Linear regression showed that except for gender, age, marital status, comorbid diabetes, smoking, systolic and diastolic blood pressure, HDL-C and LDL-C were associated with risk of coronary heart disease (P<0.05); CESD was the only factor associated with the risk of coronary heart disease [B=0.019, 95% CI: (0.015, 0.032), P=0.032]. 【Conclusion】 The risk of coronary heart disease is higher in middle-aged and elderly people with depressive symptoms than in those without depressive symptoms. Having depressive symptoms is one of the risk factors for coronary heart disease in middle-aged and elderly people.

Prevalence and characteristics of comorbid insomnia and sleep apnea in community population / 中华健康管理学杂志

Objective:To analysis the prevalence and characteristics of comorbid insomnia and sleep disordered breathing (SDB) in community population.Methods:This is a cross-sectional study. Cluster sampling was applied. Community residents in Shantou and Meizhou were investigated during April to May, 2021. Essential information collection, sleep related health investigation, and sleep study were conducted. Insomnia was defined as the insomnia severity index (ISI)≥8. A type Ⅳ wearable intelligent sleep monitor was applied for sleep study. Comorbid insomnia and SDB was defined as both diagnosis of insomnia and SDB. Statistical analysis was conducted by SPSS 25. Prevalence and characteristics of insomnia only, SDB only and comorbid insomnia and SDB were analyzed. Logistic regression was conducted to analyze the relationship between sleep disorders and unrestored sleep, abnormal glucose metabolism, hyperlipidemia, and cardiovascular disease.Results:There were 3 730 residents completed the investigation. The median age was 55.0 (46.0, 63.0) years. The prevalence of insomnia only, SDB only, and comorbid insomnia and SDB were 26.0%, 20.2%, and 10.4% respectively. The incidence of unrestored sleep in insomnia only and comorbid insomnia and SDB were 2.900 times and 3.777 times of that in no insomnia or SDB (both P<0.001); the risk of hyperlipidemia was elevated in insomnia only, SDB only and comorbid insomnia and SDB ( OR=1.553, 1.415, and 1.868; all P<0.05); the risk of cardiovascular disease increased 40.8% in SDB only ( P=0.001), and 42.1% in comorbid insomnia and SDB ( P=0.007), after adjusted by age, sex, body mass index (BMI), smoking, drinking, abnormal glucose metabolism, and hyperlipidemia. Stratified analysis revealed that young female (age<60 years) with normal BMI (<25 kg/m 2) and comorbid insomnia and SDB were associated with higher risk of cardiovascular disease. Female with normal body weight and insomnia only or comorbid insomnia and SDB were associated with higher risk of hyperlipidemia. Conclusions:The prevalence of comorbid insomnia and SDB is high in community population. Patients with comorbid insomnia and SDB present with more significant unrestored sleep, and are correlated with higher risk of hyperlipidemia and cardiovascular diseases.

Impact of the COVID-19 Outbreak on the Antibiotic Use Patterns among a Rural Community Population in Eastern China.

There are growing concerns that the coronavirus disease of 2019 (COVID-19) pandemic may change antibiotic use patterns and accelerate antibiotic resistance, but evidence from the community level is lacking. This study aims to estimate the impact of the COVID-19 outbreak on the antibiotic use patterns among a community population in Eastern China. A self-administered medicine diary was used to collect information on antibiotic use from July 2019 to June 2021 among a rural community in Eastern China. We analyzed the changes in antibiotic use patterns over five months from August to December 2019 and the corresponding months in 2020. The risk of antibiotic use and its changes were measured with the incidence rate (IR) and relative risk (RR). In total, 1111 participants were eligible for the final analysis (440 in 2019 and 671 in 2020). After the COVID-19 outbreak, antibiotic use increased by 137% (5.43 per 100 person months in the 2019 vs. 12.89 per 100 person months in the 2020), and after the adjustment of covariates, the adjusted RR was 1.72 (95% CI: 1.10~2.34). It was higher among those who were women (RR = 2.62), aged 35−59 years old (RR = 2.72), non-farmers (RR = 2.75), had less than six years of education (RR = 2.61), had an annual household income over CNY 100,000 (USD 14,940) (RR = 2.60), and had no history of chronic diseases (RR = 2.61) (all p < 0.05). The proportion of cephalosporins consumed increased from 54.29% in 2019 to 64.92% in 2020 (p = 0.011). Among those aged 35 years and older, the proportion of antibiotics obtained from medical facilities increased, while the proportion obtained from retail pharmacies, homes, and other sources decreased (all p < 0.05). The COVID-19 outbreak changed antibiotic use patterns in this study population (Eastern China) significantly. More efforts to monitor and enhance antibiotic stewardship activities at the community level are needed in future.

Sex- and body mass index-specific reference intervals for serum leptin: a population based study in China.

BACKGROUND: Leptin is a peptide hormone secreted by adipose tissue and is an important determinant of obesity and its complications. The purpose of this study was to establish sex- and body mass index (BMI)-specific reference intervals for serum leptin in a Chinese population and investigate the factors influencing leptin concentrations. METHODS: Fasting serum leptin levels were assayed in 469 men and 773 women from randomly sampled Chinese residents. Blood glucose, insulin, hemoglobin A1c (HbA1c), liver enzymes, blood lipid profiles, creatinine, and uric acid (UA) levels were measured. Pearson's correlation coefficient and multiple linear regression analyses were used to estimate the relationship between serum leptin level and other variables. The reference intervals were determined by the 2.5th and 97.5th percentiles. RESULTS: The mean ± standard deviation serum leptin level was much higher in women (20.92 ± 12.96 ng/mL) than in men (6.45 ± 5.53 ng/mL). The reference interval of serum leptin was 0.33-19.85 ng/mL in men and 3.60-54.86 ng/mL in women. The specific reference intervals of serum leptin in men with BMI of 20 to < 25 and 25 to < 27.5 kg/m2 were 0.42-12.32 and 2.17-20.22 ng/ml, respectively. The specific reference intervals of serum leptin in women with BMI of 20 to < 25 and 25 to < 27.5 kg/m2 were 4.11-38.09 and 8.27-48.66 ng/ml, respectively. BMI was significantly correlated with Ln (leptin) both in men (r = 0.698, P < 0.001) and women (r = 0.626, P < 0.001). In multivariate linear regression analysis, serum leptin was correlated with BMI, homeostasis model assessment of insulin resistance (HOMA-IR), UA in women, and plus triglyceride (TG) in men. The variance in serum leptin levels could be partially explained by these variables in both women (adjusted R2 = 0.447) and men (adjusted R2 = 0.552). In participants with leptin levels higher than the reference intervals, significantly higher levels of HOMA-IR, low-density lipoprotein cholesterol (LDL-C), UA, a higher proportion of central obesity (waist circumference [WC] > 90 cm), and metabolic syndrome were found in men, and significantly higher levels of HOMA-IR, UA and a higher proportion of central obesity (WC > 85 cm) were found in women. CONCLUSION: This is the first study to establish sex- and BMI-specific reference intervals of leptin for both sexes in a large Chinese population. Serum concentration of leptin was predicted by BMI, HOMA-IR, UA in women, and TG in men.

Patterns and Determinants of Antibiotic Use Behaviors among Rural Community Residents in Eastern China.

Inappropriate antibiotic use may lead to antibiotic resistance, which has become a serious global crisis. Addressing suboptimal antibiotic use in the general population can play a significant role in the fight against antimicrobial resistance. This study aims to describe antibiotic use and sources of acquisition, and to identify factors influencing antibiotic access among rural community residents in Eastern China. A cross-sectional survey was conducted from July to August 2020, and 1494 participants from two villages in Eastern China were enrolled. Information was obtained using face-to-face interviews with a structured electronic questionnaire. Chi-squared and multinominal logistic regression analysis were used to explore possible determinants. In total, 1379 participants were eligible for the analysis. In the past 12 months, nearly half the respondents had taken any antibiotic (48.4%), and this proportion varied across marital status and age group. Two thirds of them (59.9%) obtained antibiotics from medical facilities with a prescription when they last took antibiotics, while 17.7% and 22.4% chose retail pharmacies and other sources, respectively. Multinominal analysis found that a higher proportion obtained antibiotics outside medical facilities among those aged 15 to 44 years, unmarried, non-white collar workers, with more years of education, lower annual household income per capita and lower levels of antibiotic knowledge. The antibiotic use behavior of rural community residents in Eastern China remains suboptimal. Antibiotic use and access behaviors need to be further addressed. Effective antibiotic stewardship in non-medical facility sources and training programs targeted for rural Chinese is warranted in future.

Roles of Psychological Distress and Social Support in the Relationship Between Childhood Maltreatment and Perceived Needs for Mental Health Care.

Childhood maltreatment is a major public health issue worldwide. It increases a range of health-risk behaviors, psychological and physical problems, which are associated with an increased need for mental health services in adulthood. Identification of mediating factors in the relationship between maltreatment and seeking mental health care may help attenuate the negative consequences of childhood maltreatment and promote more appropriate treatment. This study aims to examine whether the relationship between childhood maltreatment and perceived need for mental health care is mediated by psychological distress and/or moderated by social support. Data from the Canadian Community Health Survey-Mental Health 2012 are analyzed. A total of 8,993 participants, who had complete information on childhood maltreatment and diagnoses of mental disorders or psychological distress, are included in this study. Structural equation modeling and the PROCESS macro were used to identify relationships among childhood maltreatment, perceived needs for mental health care, and psychological distress. Hierarchical linear regression was then used to verify the moderated mediation model. We found that psychological distress partially mediated the effect of childhood maltreatment on perceived needs for mental health care in adulthood. Social support played an important role in terms of moderating the relationship between maltreatment and perceived needs for care. For those with a history of childhood maltreatment, those who perceived a low level of social support were more likely to have higher levels of psychological distress and perceived need for mental health care. This is the first study to identify the separate and combined roles of psychological distress and social support in the relationship between childhood maltreatment and perceived need for mental health care. Selective prevention strategies should focus on social support to improve mental health services among people with a history of childhood maltreatment.

Relationship between sleep duration, sleep time and brachial-ankle pulse wave velocity / 中华内分泌代谢杂志

Objective:Explore the relationship between sleep duration, sleep time and brachial-ankle pulse wave velocity(baPWV) in community population.Methods:Questionnaire, physical examination, blood tests, and baPWV detection were applied to a community based population. Finally, 3 912 subjects with complete data were included in the study. The relationship between sleep duration, time to fall asleep and PWV was evaluated with binary logistic regression analysis. Results:Being adjusted for age, sex, prevalence of diabetes, sleep condition, body mass index, blood glucose, blood pressure, dyslipidemia, ankle-brachial index, sleep duration and time to fall asleep were correlated with PWV. The risk of PWV abnormalities was increased in the≥8 h group compared to the 6-8 h group( OR=1.155, 95% CI 0.995-1.367, P=0.037). The risk of abnormalities PWV was higher in the group with sleep time after 00: 00 than in the group -23: 00( OR=1.482, 95% CI 1.008-2.179, P=0.045). Conclusion:Long sleep duration(≥8 h) and late sleep time(after 00: 00) may be associated with higher risk of atherosclerosis.

Increased resting heart rate and glucose metabolism in a community population.

OBJECTIVE: Resting heart rate (RHR) independently predicts cardiovascular death. Increased RHR is related to chronic diseases, but community-based studies are rare. We investigated this population and factors related to RHR. METHODS: In total, 374 participants underwent medical examinations from March 2019 to December 2019. Participants were divided into groups with low RHR (LRHR; <65 beats/minute) and high RHR (HRHR; ≥65 beats/minute). RHR was judged using resting electrocardiogram at physical examination. We conducted laboratory examinations, including glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG), and blood lipids, among participants with chronic diseases. We used Cox proportional risk regression and multivariate analyses for the following covariates: previous chronic diseases, body mass index (BMI), smoking, blood lipids, and FPG. RESULTS: The incidence of type 2 diabetes mellitus (T2DM) and HbA1c values were both significantly higher in the HRHR group than in the LRHR group. Spearman correlation analysis showed RHR had a positive correlation with low-density lipoprotein, BMI, FPG, and HbA1c (r = 0.104574, 0.117266, 0.116041, and 0.311761, respectively). Multiple linear regression analysis showed age, hypertension, T2DM, and HbA1c were factors influencing RHR. CONCLUSION: RHR showed strong correlation with T2DM and HbA1c in our community population, suggesting that RHR may be a risk factor for cardiovascular disease.

[Research progress of non-invasive examination in the screening of chronic liver disease among the general community population].

Due to its insidious nature, chronic liver disease usually only appears after a decompensating event, and delays in diagnosis lead to a high mortality. Non-invasive examination can help diagnose and intervene early stage liver fibrosis in patients with chronic liver disease. In a hospital population, this test has been widely used and appropriate; however, its value is unclear in the general community population. In recent years, there have been many studies on non-invasive examinations for foreign community populations. These non-invasive examination tools can screen patients with chronic liver disease and liver cirrhosis among the general community population. Further studies have found that screening community populations with liver disease risk factors (heavy alcohol consumption, type 2 diabetes mellitus, and obesity) can more efficiently screen out patients with chronic liver disease in the community population. In brief, these noninvasive examination can find a large number of previously undiscovered liver disease patients in the community population, compared to traditional community screening that rely on abnormal liver function testing. This paper discusses the non-invasive examination in the screening of chronic liver disease among the community population, so as to find a pioneering community non-invasive liver disease screening path for our country.

Prevalence of incidental brain MRI findings of clinical relevance in a diverse Hispanic/Latino population.

BACKGROUND AND PURPOSE: There is limited literature on the prevalence of incidental brain MRI findings in the Hispanic/Latino population, despite their increased prevalence of vascular disease and undertreatment of chronic conditions. The purpose of our study was to determine the prevalence of clinically relevant incidental findings on brain MRI examinations obtained as a part of the Study of Latinos-Investigation of NeuroCognitive Aging MRI (SOL-INCA-MRI) study. METHODS: Brain MRI examinations were obtained on 1389 participants in the SOL-INCA-MRI study, a cross-sectional ancillary study of the Hispanic Community Health Study, Study of Latinos, which is a longitudinal, community-based study. Study design of SOL-INCA-MRI involves imaging cognitively normal and participants with mild cognitive impairment. Brain MRI findings were categorized as Level 1 (normal), Level 1.5 (findings of unclear medical significance), Level 2 (potential medical concern), or Level 3 (medically urgent). This article focuses on Level 2 and Level 3 findings. RESULTS: The average age of the sample was 60.8 years (+/- 10.3 years), 66.1% were females. Level 2 and 3 findings were identified in 117 participants, (8.4%), of which 109 (7.8%) were recommended for medical follow-up (Level 2), and 8 (0.6%) were recommended for immediate medical attention (Level 3). Brain MRI findings consisted of chronic infarction in 33 (2.4%), vascular abnormality in 27 (1.9%), intracranial mass in 20 (1.4%), other intracranial findings in 28 (2.0%), and skull base/extracranial findings in 26 (1.9%) patients. CONCLUSION: Incidental findings of clinical relevance were common among SOL-INCA-MRI participants, but rarely required urgent medical intervention.

Elevated lipoprotein(a) and risk of coronary heart disease according to different lipid profiles in the general Chinese community population: the CHCN-BTH study.

BACKGROUND: To evaluate the contributions of elevated lipoprotein(a) [Lp(a)] to the risk of coronary heart disease (CHD) in the general Chinese community population according to different lipid profiles. METHODS: We recruited individuals aged over 18 years from the baseline survey of the Cohort Study on Chronic Disease of Communities Natural Population in Beijing, Tianjin and Hebei (CHCN-BTH) using a stratified, multistage cluster sampling method. Data were collected through questionnaire surveys, anthropometric measures and laboratory tests. Restricted cubic spline (RCS) functions, multivariate logistic regression, sensitivity analyses and stratified analyses were used to evaluate the association between Lp(a) and CHD. RESULTS: A total of 25,343 participants were included, with 1,364 (5.38%) identified as having CHD. Elevated Lp(a) levels were linearly related to an increased risk of CHD (Poverall-association<0.0001 and Pnonlinear-association=0.8468). Multivariate logistic regression analysis indicated that subjects with Lp(a) ≥300 mg/L had a higher risk of CHD [OR (95% CI): 1.36 (1.17, 1.57)] than did individuals with Lp(a) <300 mg/L. Compared with individuals with Lp(a) <119.0 mg/L (<50th percentile), the ORs (95% CI) for CHD in the 51st-80th, 81st-95th and >95th percentiles were 1.07 (0.93, 1.23), 1.26 (1.07, 1.50) and 1.68 (1.30, 2.17), respectively (P for trend <0.0001). This association was also found among the subgroup of subjects without dyslipidemia, including those with normal total cholesterol (TC) (<6.2 mmol/L), triglycerides (TG) (<2.3 mmol/L), high-density lipoprotein cholesterol (HDL-C) (≥1.0 mmol/L) and low-density lipoprotein cholesterol (LDL-C) (<4.1 mmol/L). Elevated Lp(a) and dyslipidemia significantly contributed to a higher risk of CHD with synergistic effects. Stratified analyses showed that elevated Lp(a) concentrations were significantly associated with an increased risk of CHD in the subgroups of individuals who were noncurrent drinkers, overweight individuals, individuals with hypertension, individuals who engaged in moderate physical activity, those without diabetes mellitus and individuals in Beijing and Tianjin. CONCLUSIONS: Elevated Lp(a) concentrations were linearly associated with a higher risk of CHD in the general Chinese community population, especially in normolipidemic subjects. Both dyslipidemia and elevated Lp(a) independently or synergistically contributed to the risk of CHD. Our results suggest that more attention should be paid to the levels of Lp(a) in normolipidemic subjects, which may be an early predictor of CHD.

Investigation on influenza vaccination status of household registration chronic disease management patients in Qingpu district / 中华微生物学和免疫学杂志

Objective:To analyze the influenza vaccination status of chronic disease management patients in Qingpu district of Shanghai and the vaccination characteristics of different characteristic populations, so as to provide scientific basis for improving the influenza vaccination rate of chronic disease patients in the community.Methods:By comparing the data of Shanghai chronic disease management information system, immunization planning information system and medical association platform, 89 453 subjects who met the inclusion and exclusion criteria in Qingpu district were selected as the research objects. The vaccination coverage rate of the study subjects was calculated according to gender, age group, urban and rural distribution, occupation, chronic disease type and quantity, and the vaccination coverage rate of different subgroups was compared to analyze the influencing factors of vaccination coverage rate.Results:Most of the 89 453 patients with chronic diseases were 60 years old and above (71.93%). Patients with hypertension, diabetes, chronic obstructive pulmoriary disease (COPD) and three chronic diseases accounted for 87.12%, 28.67%, 8.71% and 1.83%, respectively. Influenza vaccination coverage in the 2016/2017 flu season was low, at 0.32%. Influenza vaccination coverage rate of women (0.37%) was higher than that of men (0.27%), which was 1.41 times respectively(95% CI: 1.16, 1.72) that of men patients. The coverage rate of influenza vaccination for the 70-79 year-old group was the highest (0.74%), which was 1.74 times respectively(95% CI: 1.39, 2.19) that of 60-69 year-old patients. The vaccination coverage rate of government departments and institutions was the highest (1.14%), which was 12.58 times respectively(95% CI: 4.52, 34.99) that of retirees. The vaccination rate of COPD patients (3.68%) was 2.50 times (95% CI: 1.66, 3.77) higher than that of patients without COPD.Conclusions:Influenza vaccination rate for chronic disease management patients in Qingpu district of Shanghai is low. Gender, occupation, age and types of chronic diseases are the influencing factors. Patients with chronic disease management should be included in the priority vaccination targets for influenza vaccines, and vaccination intervention for occupational chronic diseases such as non-retired agriculture and forestry patients, especially male patients, should be strengthened to improve influenza vaccination coverage rate.

The Prevalence of Thrice, Twice, and Once Human Papillomavirus DNA Positivity in Older Chinese Women.

Background: Human papillomavirus (HPV) DNA detection in cervical samples is widely used to identify HPV infection; however, there is little detailed evaluation of the characteristics of HPV prevalence by repeated DNA detection in community populations. Methods: Beginning in 2014, a Papanicolaou (Pap) smear and HPV cotesting program was implemented among older women living in the Minhang district of Shanghai. This report uses information from 225,000 participants, who provided person-time data. Of these, 632 subjects had 3 repeated visits and at least one HPV DNA-positive result in the last 5 years. Results: All 16 genotypes of HPV displayed thrice, twice, and once positivity results in 3 repeated tests and differed by proportions among and within genotypes. HPV52 and 58 are the two most dominant genotypes in total and in thrice positive person-time. The thrice positive person-time exceeded 50% in each of HPV58-, 35-, 52-, 56-, 18-, 68-, 31-, and 16-infected women. The single positive person-time ratio ranged from 7.9% (HPV35) to 38.9% (HPV11). Age differed among and within genotypes in thrice, twice, and once positive women. The average age of HPV-free controls was 59.0 ± 7.2 yo, which is close to the median of average ages for thrice and twice positive women and is older than most average ages for once positive women. The percentages of negative results for intraepithelial lesion or malignancy (NILM) for thrice HPV52-, 58-, 16-, 56-, and 59-positive women were significantly lower than the percentage of NILM for HPV-free women. Conclusion: Thrice and/or twice HPV DNA positivity are common in HPV-infected women and tend to occur in older women.
