The microbiota in patients with interstitial cystitis/bladder pain syndrome: a systematic review.

OBJECTIVE: To comprehensively review and critically assess the literature on microbiota differences between patients with interstitial cystitis (IC)/bladder pain syndrome (BPS) and normal controls and to provide clinical practice guidelines. MATERIALS AND METHODS: In this systematic review, we evaluated previous research on microbiota disparities between IC/BPS and normal controls, as well as distinctions among IC/BPS subgroups. A comprehensive literature search was conducted across PubMed/MEDLINE, EMBASE, Web of Science, and the Cochrane Central Register of Controlled Trials. Relevant studies were shortlisted based on predetermined inclusion and exclusion criteria, followed by quality assessment. The primary focus was identifying specific taxonomic variations among these cohorts. RESULTS: A total of 12 studies met the selection criteria. Discrepancies were adjudicated by a third reviewer. The Newcastle-Ottawa Scale was used to assess study quality. Predominantly, the studies focused on disparities in urine microbiota between IC/BPS patients and normal controls, with one study examining gut microbiota differences between the groups, and two studies exploring vaginal microbiota distinctions. Unfortunately, analyses of discrepancies in other microbiota were limited. Our findings revealed evidence of distinct bacterial abundance variations, particularly involving Lactobacillus, alongside variations in specific metabolites among IC/BPS patients compared to controls. CONCLUSIONS: Currently, there is evidence suggesting significant variations in the diversity and species composition of the urinary microbiota between individuals diagnosed with IC/BPS and control groups. In the foreseeable future, urologists should consider urine microbiota dysbiosis as a potential aetiology for IC, with potential clinical implications for diagnosis and treatment.

[Association between tea drinking and the risk of type 2 diabetes mellitus among rural adults in Deqing County:a prospective cohort study].

OBJECTIVE: To explore the associations between tea drinking and the incident risk of type 2 diabetes mellitus(T2 DM). METHODS: A dynamic prospective cohort study among a total of 27 841 diabetes-free permanent adult residents randomly selected from 2, 6 and 7 rural communities between 2006-2008, 2011-2012 and 2013-2014, respectively. Questionnaire survey, physical examination, and laboratory test were carried out among the participants. In 2018, we conducted a follow-up through the electronic health records of residents. Cox regression model were applied to explore the association between tea drinking and the incident risk of T2 DM and estimate the hazard ratio(HR), and its 95%CI. RESULTS: Among the 27 841 rural community residents in Deqing County, there were 10 726(38.53%) were tea drinkers, 8215 of which were green tea drinkers, accounting for 76.59%. Totally 883 new T2 DM incidents were identified until December 31, 2018, and the incidence density was 4.43 per 1000 person years(PYs). The incidence density was 4.07/1000 PYs in those with tea drinking habits and 4.71/1000 PYs in those without tea drinking habits, among which the incidence density was 3.79/1000 PYs in those with green tea drinking habits. After controlling for sex, age, education, farming, smoking, alcohol consumption, dietary preference, body mass index, hypertension, impaired fasting glucose, family history of diabetes, the risk of T2 DM among rural residents with tea drinking habits in Deqing County was 0.79 times higher than that among residents without tea drinking habits(HR=0.79, 95%CI 0.65-0.96), and the risk of T2 DM among residents with green tea drinking habits was 0.72 times higher than that among residents without tea drinking habits(HR=0.72, 95%CI 0.58-0.89). However, no significant associations were found between other kinds of tea and the risk of T2 DM, nor the amount of green tea to drink. CONCLUSION: Drinking green tea may reduce the risk of T2 DM among adult population in rural China.

Associations between serum amino acids and incident type 2 diabetes in Chinese rural adults.

BACKGROUND AND AIMS: Some amino acids (AAs) may be associated with type 2 diabetes (T2DM). This study aimed to determine the associations of individual AAs with the development of T2DM in rural Chinese adults. METHODS AND RESULTS: A cohort study of 1199 individuals aged 18 years or older was conducted from 2006 to 2008 in a rural community of Deqing, China, a repeated survey was done in 2015 and data linkage with the electronic health records system was performed each year for identifying new T2DM cases. A high-performance liquid chromatography approach was used to measure the baseline serum concentrations of 15 AAs. Cox proportional hazards models were used to examine the associations between AAs and the risk of incident T2DM. A total of 98 new T2DM cases were identified during the follow-up of 12 years on average. Among 15 AAs, proline was associated with an increased risk of incident T2DM after adjusted for age, sex, body mass index, fasting plasma glucose, family history of T2DM, smoking status, alcohol use, and history of hypertension, the adjusted hazard ratio for 1-standard deviation increment was 1.20 (95% confidence interval: 1.00, 1.43). The association tended to be more marked in subjects younger than 60 years and overweight/obese subjects. Among participants without hypertension, proline and phenylalanine were associated with an increased risk of incident T2DM, while aspartic acid was associated with a decreased risk. CONCLUSION: Serum proline was associated with the risk of incident T2DM in rural Chinese adults and might be a potential predictor.

Study problems and depressive symptoms in adolescents during the COVID-19 outbreak: poor parent-child relationship as a vulnerability.

BACKGROUND: Little is known about the prevalence of and risk factors for adolescent mental health problems during the COVID-19 outbreak. We aimed to investigate the prevalence of depressive symptoms, their association with study-relevant problems, and the moderating effect of parent-child relationship among Chinese adolescents during the school closures. METHODS: We performed a cross-sectional analysis with data collected in middle and high schools in Taizhou, China. Students completed an online survey between April 16 and May 14, 2020. Depressive symptoms were assessed using the Children's Depression Inventory. Three types of study problems were recorded, including having difficulty in studying at home, dislike of remote learning, and excessive screen entertainment time. Parental relationships were categorized into good or normal relationship and poor relationship. Linear regression and logistic regression analyses were conducted to investigate the associations between study-relevant problems and depressive symptoms. RESULTS: Using data from 6435 adolescents, we found that the prevalence of depressive symptoms was 17.7%. All the study problem measures were associated with more severe depressive symptoms. There was a moderating effect of the parental relationship on the associations between study problems and depressive symptoms. The association between number of study problems and depressive symptoms was stronger in adolescents with a poor parent-child relationship (regression coefficient 4.34 [95% CI 2.97, 5.72]) than those with a good or normal relationship (2.55 [2.35, 2.75]), p for interaction 0.002, on multivariable adjustment. CONCLUSIONS: Study problems due to school closures were particularly problematic for adolescents who had poor parent-child relationships. Public health initiatives could help students to adjust study habits and improve parent-child relationships, thereby protecting against the development of depression.

Prevalences of metabolic syndrome and its sex-specific association with socioeconomic status in rural China: a cross-sectional study.

BACKGROUND: Few studies have reported the prevalence of metabolic syndrome (MS) and examined relationships between socioeconomic status and MS in rural China. This study aimed to evaluate the prevalence of MS and MS components as well as their associations with socioeconomic status among rural Chinese adults. METHODS: A cross-sectional study of 26,836 participants aged 20 years and older was conducted from June to December 2012 in Yuhuan City, Zhejiang Province, China, which is located on Yuhuan Island. A multivariable logistic regression model was used to identify risk factors for MS and their possible interactions. RESULTS: Among 26,836 subjects with an average age of 53.4 ± 14.0 years, 59% were female. The overall prevalence of MS was 20.5%, and there was a significant sex difference in the prevalence (15.1% for males vs. 24.2% for females, P < 0.001). Compared with males, females also showed a significantly higher proportion of most MS components. A significantly higher prevalence of MS was found among subjects who were elderly, had a lower income level, had a lower level of education, or were unemployed. Multiple significant interactions were observed between the prevalence of MS and sex, age or socioeconomic status (P < 0.001). The risk of MS increased significantly with age in females but not in males. Additionally, a lower income level and a lower level of education were significantly related to an increased risk only in females, and unemployed males had a higher risk of MS than unemployed females. CONCLUSIONS: The prevalence of MS and its components was relatively high in a rural island Chinese population with rapid urbanization, and sex-specific associations between socioeconomic factors and MS were found. Targeted preventive interventions should be developed and implemented to prevent and control MS among those with low socioeconomic status, especially females.

Quality of life during the epidemic of COVID-19 and its associated factors among enterprise workers in East China.

BACKGROUND: The COVID-19 related lockdown and home confinement might have an important impact on the quality of life in enterprise workers. We investigated the quality of life during the epidemic in enterprise workers who just returned to work, and assessed its potential influencing factors to have a better understanding of the impact of COVID-19 epidemic lockdown and home confinement. METHODS: This was a cross-sectional study of enterprise workers conducted in Deqing and Taizhou, Zhejiang Province, China. The Chinese version of EQ5D was used to assess life quality, and information about general characteristics and COVID-19 related factors was collected by a structured questionnaire, which was distributed through the social application "WeChat". Multiple liner regression was used to investigate potential influencing factors. RESULTS: A total of 2420 participants were enrolled, 59.5% of which worked in Deqing. About 50% of the participants reported worries about the COVID-2019 epidemic and 40.2% had a centralized or home quarantine during the epidemic. The mean EQ-5D score and VAS were 0.990 and 93.5. Multiple liner regression showed that the quality of life measures was related to physical activities (ß = 0.006) and keeping home ventilation (ß = 0.063) in Deqing, and were related to wearing a mask when going out (ß = 0.014), keeping home ventilation (ß = 0.061), other marital status (ß = - 0.011), worry about the epidemic (ß = - 0.005) and having a centralized or home quarantine (ß = - 0.005) in Taizhou. CONCLUSIONS: The quality of life for returning enterprise workers in areas with different risks of COVID-19 was affected by different factors. Associated factors identified from this study would help develop proper intervention measures for enterprise workers to reduce the impact of large-scale public health events like the COVID-19 on their quality of life.

Depression and anxiety symptoms among returning workers during the COVID-19 period in East China.

PURPOSE: To determine the prevalence of depression and anxiety and associated factors among returning workers with different epidemic experience in East China. METHODS: A cross-sectional study was conducted among 2435 employees from the enterprises located in Deqing (low-risk epidemic area) and Taizhou (high-risk epidemic area) of East China in March 2020. An online questionnaire covered information on sociodemographic and lifestyle factors as well as knowledge, attitude, behavior and experience about COVID-19. The Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder-7 (GAD-7) were applied to assess depression and anxiety symptoms, respectively. Logistic regression model was used to estimate adjusted odds ratios (aORs) and their 95% confidence intervals (CIs) for depression and anxiety symptoms associated with risk factors. RESULTS: The participants were aged 36.3 ± 9.2 years on average, and nearly half of them were female. Overall, the prevalence of depression, anxiety and both were 19.4%, 12.3% and 9.8%, and decreased with age. After adjustment for covariates, 16 or more years of education, being a white-collar worker or working in the high-risk epidemic area were significantly associated with increased risks of both depression and anxiety, in contract regular physical exercise was associated with decreased risks of both mental disorders. CONCLUSION: The depression and anxiety problems were prevalent among returning workers during the COVID-19 period. Targeted psychological interventions should be developed and implemented to improve their mental health.

Health related quality of life and its impacts by chronic diseases in urban community population, Shanghai, China in 2015.

This survey aimed to describe the health-related quality of life (HRQoL) and to explore the relationship between chronic diseases and HRQoL among urban residents in Shanghai, China. A cross-sectional study of 9 426 adults was conducted in Xuhui District of Shanghai, China in 2015. The EuroQol five-dimension three-level (EQ-5D-3 L) was used to measure HRQoL. The average age of subjects was 55.6 ± 17.4 years and 53% were female. Their mean values of utility and visual analogue scale (VAS) were 0.974 ± 0.099 and 80.00 ± 12.36, respectively, which were above the Chinese norm values. Women had lower scores compared with men. The utility value decreased with age, which accelerated after the age of 55 years. Chronic conditions including diabetes, tumor, cardiovascular disease, and respiratory disease, were significantly related to HRQoL, and the reported proportions of problems in the five dimensions increased with the number of chronic diseases (p < 0.05). Chronic diseases except for respiratory disease had a negative effect on HRQoL utility value and VAS score after the adjustment for covariates (p < 0.05). Chronic diseases had a negative impact on both EQ-5D-3 L utility and VAS scores, although the health-related quality of life for the study was above the national average.

Peripheral anterior chamber depth and screening techniques for primary angle closure disease in community elderly Chinese.

BACKGROUND: To investigate the distribution of peripheral anterior chamber depth (ACD) and the relationship between peripheral ACD and gonioscopy compared to other ocular parameters for primary angle closure disease (PACD) screening. We performed a population-based survey in Pudong New District of Shanghai, China, in 2011. METHODS: Cross-sectional study. Adults 50 and older were enrolled from a population-based study using cluster random sampling in Pudong New District, Shanghai. Remote ocular screening was performed with digital anterior eye structure photography. Van Herrick measurements were used to evaluate the peripheral ACD, the depth of the peripheral anterior chamber, and corneal thickness (CT), and the ACD to CT ratio was calculated. Subjects with peripheral ACD less than 0.5 CT were made follow-up appointments for clinical examination with gonioscopy. Receiver operating characteristic curves (ROC) were generated to show the performance of different tests in screening for primary angle closure disease (PACD). RESULTS: Two thousand five hundred twenty-eight adults participated in the study with 91 patients diagnosed with PACD. Two thousand four hundred sixty-three subjects had valid data in the right eye available for analysis. The mean peripheral ACD values for men and women were significantly different: 1.04 ± 0.46 (range 0.11-2.93) CT and 0.87 ± 0.41 (range 0.12-2.96) CT respectively (t = - 4.18; P<0.0001). Multivariate logistic regression analysis reveals that peripheral ACD declined by 0.31 CT (P < 0.0001) per diopter of SE and was 0.19 CT (P < 0.0001) shallower in women than in men (r2 = 0.1304, P < 0.0001). Peripheral ACD performed best in screening for PACD. CONCLUSIONS: Peripheral ACD measurement is recommended for PACD screening in community elderly Chinese.

Anatomy of provincial level inequality in maternal mortality in China during 2004-2016: a new decomposition analysis.

BACKGROUND: The maternal mortality ratio (MMR) is an important indicator of maternal health and socioeconomic development. Although China has experienced a large decline in MMR, substantial disparities across regions are still apparent. This study aims to explore causes of socioeconomic related inequality in MMR at the province-level in China from 2004 to 2016. METHODS: We collected data from various issues of the China Health Statistics Yearbook, China Statistics Yearbook, and China Population and Employment Statistics Yearbook to construct a longitudinal sample of all provinces in China. We first examined determinants of the MMR using province fixed-effect models, accounted for socioeconomic condition, health resource allocation, and access to health care. We then used the concentration index (CI) to measure MMR inequality and employed the direct decomposition method to estimate the marginal impact of the determinants on the inequality index. Importance of the determinants were compared based on logworth values. RESULTS: During our study period, economically more deprived provinces experienced higher MMR than better-off ones. There was no evidence of improved socioeconomic related inequality in MMR. Illiteracy proportion was positively associated with the MMR (p < 0.01). In contrast, prenatal check-up rate (p = 0.05), hospital delivery rate (p < 0.01) and rate of delivery attended by professionals (p = 0.02) were negatively associated with the MMR. We also find that higher maternal health profile creation rate (p < 0.01) was associated with a pro-poor change of MMR inequality. CONCLUSION: Access to healthcare was the most important factor in explaining the persistent MMR inequality in China, followed by socioeconomic condition. We do not find evidence that health resource allocation was a contributing factor.

Current situation and progress toward the 2030 health-related Sustainable Development Goals in China: A systematic analysis.

BACKGROUND: The Sustainable Development Goals (SDGs), adopted by all United Nations (UN) member states in 2015, established a set of bold and ambitious health-related targets to achieve by 2030. Understanding China's progress toward these targets is critical to improving population health for its 1.4 billion people. METHODS AND FINDINGS: We used estimates from the Global Burden of Disease (GBD) Study 2016, national surveys and surveillance data from China, and qualitative data. Twenty-eight of the 37 indicators included in the GBD Study 2016 were analyzed. We developed an attainment index of health-related SDGs, a scale of 0-100 based on the values of indicators. The projection model is adjusted based on the one developed by the GBD Study 2016 SDG collaborators. We found that China has achieved several health-related SDG targets, including decreasing neonatal and under-5 mortality rates and the maternal mortality ratios and reducing wasting and stunting for children. However, China may only achieve 12 out of the 28 health-related SDG targets by 2030. The number of target indicators achieved varies among provinces and municipalities. In 2016, among the seven measured health domains, China performed best in child nutrition and maternal and child health and reproductive health, with the attainment index scores of 93.0 and 91.8, respectively, followed by noncommunicable diseases (NCDs) (69.4), road injuries (63.6), infectious diseases (63.0), environmental health (62.9), and universal health coverage (UHC) (54.4). There are daunting challenges to achieve the targets for child overweight, infectious diseases, NCD risk factors, and environmental exposure factors. China will also have a formidable challenge in achieving UHC, particularly in ensuring access to essential healthcare for all and providing adequate financial protection. The attainment index of child nutrition is projected to drop to 80.5 by 2025 because of worsening child overweight. The index of NCD risk factors is projected to drop to 38.8 by 2025. Regional disparities are substantial, with eastern provinces generally performing better than central and western provinces. Sex disparities are clear, with men at higher risk of excess mortality than women. The primary limitations of this study are the limited data availability and quality for several indicators and the adoption of "business-as-usual" projection methods. CONCLUSION: The study found that China has made good progress in improving population health, but challenges lie ahead. China has substantially improved the health of children and women and will continue to make good progress, although geographic disparities remain a great challenge. Meanwhile, China faced challenges in NCDs, mental health, and some infectious diseases. Poor control of health risk factors and worsening environmental threats have posed difficulties in further health improvement. Meanwhile, an inefficient health system is a barrier to tackling these challenges among such a rapidly aging population. The eastern provinces are predicted to perform better than the central and western provinces, and women are predicted to be more likely than men to achieve these targets by 2030. In order to make good progress, China must take a series of concerted actions, including more investments in public goods and services for health and redressing the intracountry inequities.

UCP2 and UCP3 variants and gene-environment interaction associated with prediabetes and T2DM in a rural population: a case control study in China.

BACKGROUND: There are disparities for the association between uncoupling proteins (UCP) and type 2 diabetes (T2DM). The study was to examine the associations of genetic variants of UCP2 and UCP3 with prediabetes and T2DM in a rural Chinese population. METHODS: A population-based case-control study of 397 adults with T2DM, 394 with prediabetes and 409 with normal glucose tolerance (NGT) was carried out in 2014 in a rural community in eastern China. Three groups were identified through a community survey and the prediabetes and NGT groups were frequently matched by age and gender with the T2DM group and they were not relatives of T2DM subjects. With r2 ≥ 0.8 and minor allele frequency (MAF) ≥0.05 for tag single nucleotide polymorphisms (SNPs) with potential function, three (rs660339, rs45560234 and rs643064) and six (rs7930460, rs15763, rs647126, rs1800849, rs3781907 and rs1685356) SNPs were selected respectively for UCP2 and UCP3 and genotyped in real time using the MassARRAY system (Sequenom; USA). The haplotypes, gene-environmental interaction and association between genetic variants of UCP2 and UCP3 and prediabetes or T2DM were explored. RESULTS: There were no significant differences in age and sex among three study groups. After the adjustment for possible covariates, the A allele of rs1800849 in UCP3 was significantly associated with prediabetes (aORAA vs GG = 1.68, 95% CI: 1.02-2.78), and the association was also significant under the recessive model (aOR AA vs GA + GG = 1.64, 95% CI: 1.02-2.66). Also, rs15763 was found to be marginally significantly associated with T2DM under dominant model (ORGA + AA vs GG = 0.73, 95% CI: 0.52-1.03, P = 0.072). No haplotype was significantly associated with prediabetes or T2DM. Multiplicative interactions for rs660339-overweight on T2DM were observed. In addition, the AA genotype of rs660339 was associated with an increased risk of T2DM in overweight subjects (OR = 1.48, 95%CI: 0.87-2.52) but with a decreased risk in those with normal weight (OR = 0.54, 95%CI: 0.28-1.05). CONCLUSIONS: Rs1800849 in UCP3 was significantly associated with prediabetes. Overweight might modify the effects of rs660339 of UCP2 on T2DM.

Prevalence of anxiety and depression symptoms and their associated factors in mild COPD patients from community settings, Shanghai, China: a cross-sectional study.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a serious disease frequently accompanied by anxiety and depression. Few studies have focused on anxiety and depression for mild COPD patients in China. This study aimed to assess the prevalence and associated factors for anxiety and depression among patients with mild COPD in urban communities. METHODS: A cross-sectional survey of 275 mild COPD patients was conducted in 6 communities randomly sampled from Pudong New Area of Shanghai, China, in 2016. Data on socioeconomic factors and health conditions were acquired through a face-to-face interview as well as a physical examination. The Hospital Anxiety and Depression Scale (HAD) and EQ-5D visual analogue (EQ-5Dvas) were applied to evaluate their mental health and quality of life, respectively. Logistic regression model was used to estimate adjusted odds ratios (aORs) and their 95% confidential intervals (CI) for risk factors associated with anxiety or depression. RESULTS: Among 275 subjects, 8.1% had anxiety and 13.4% had depression. Logistic regression analysis indicated that female patients were more likely to suffer from anxiety than male patients (aOR = 6.41, 95% CI:1.73-23.80). Poor health status (EQ-5Dvas score < 70) was significantly associated with increased risks of anxiety (aOR = 5.99, 95% CI: 2.13-16.82) and depression (aOR = 2.67, 95% CI: 1.29-5.52). CONCLUSIONS: There were increased risks of anxiety and depression in mild COPD patients living in urban communities. Female sex and poor health status were significantly correlated to anxiety or depression. More interventions should be developed to reduce the risks of anxiety and depression at the early stage of COPD.

Poor sleep quality and influencing factors among rural adults in Deqing, China.

BACKGROUND: Poor sleep quality is prevalent and is associated with cognitive decline, impaired health, and reduced quality of life. There is a lack of studies about sleep quality and its potential risk factors among rural adults aged 45 years or above under rapid urbanization in China. METHODS: In a cross-sectional survey conducted in Deqing County, China in 2015, we included 1584 adults 45+ years of age. Sleep quality was measured by using the Chinese version of the Pittsburgh Sleep Quality Index (CPSQI). Poor sleep quality was defined by a CPSQI global score > 5. Other data collected included sociodemographic and lifestyle factors as well as physical health. Logistic regression model was applied to assess factors influencing sleep quality by calculating crude odds ratio (cOR), adjusted OR (aOR), and their 95% confident intervals (CI). RESULTS: Of 1584 subjects, more than half were female with an average age of 58.9 ± 8.1 years. Their night sleep duration was 7.7 ± 1.2 h, sleep latency was 31.9 ± 32.0 min, and 17% of them could not fall asleep within half hour, averagely. The mean score of CPSQI was 4.4 ± 2.7. The prevalence of poor sleep quality was 27.7% (95% CI = 25.4-29.7%) overall, and there existed a significant sex difference-30.6% (95% CI = 27.7-33.7%) for women and 24.0% (95% CI = 20.9-27.2%) for men. Five domains of the CPSQI except for sleep efficiency and use of sleeping medication also showed a sex difference (p < 0.05). Logistic regression analysis indicated that unmarried status (aOR = 1.51, 95% CI = 1.03-2.22), lower monthly individual income (aOR = 2.09, 95% CI = 1.49-2.94), and chronic diseases (aOR = 1.95, 95% CI = 1.51-2.51) were significantly related to poor sleep quality. CONCLUSIONS: Sleep problems were prevalent among the rural Chinese adults aged 45+ years. People who were unmarried or had low personal income or any chronic diseases were more likely to have poor sleep quality.

The dermatology life quality index (DLQI) and the hospital anxiety and depression (HADS) in Chinese rosacea patients.

The study aims to investigate the quality of life (QOL) and the psychological situation in Chinese patients with rosacea. A total of 196 healthy controls and 201 rosacea patients were involved in the final analysis. The general information, the Dermatology Life Quality Index (DLQI) and the Hospital Anxiety and Depression Scale (HADS) were collected. Significantly higher DLQI, anxiety and depression score were observed in the rosacea group compared to the control group (p < .01). Total DLQI score of patients was positively related with anxiety (r = .526, p < .001) and depression scores (r = .399, p < .001) in HADS. Rosacea had significant psychological impact on Chinese patients and had substantial influence on their QOL. Physicians should address the psychosocial needs of rosacea patients as much as its physical symptoms.

Urinary Antibiotics of Pregnant Women in Eastern China and Cumulative Health Risk Assessment.

Exposure to antibiotics during pregnancy can pose a systematic effect on human health. A few biomonitoring studies have demonstrated an extensive exposure of children to antibiotics, but there is still a lack of data for pregnant women. To assess the exposure of pregnant women to antibiotics and potential health risk, we investigated 536 pregnant women aged 16-42 years from two geographically different study sites in Eastern China in 2015. We measured 21 antibiotics of five categories (seven fluoroquinolones, three phenicols, four tetracyclines, three macrolides, and four sulfonamides) in urine using the isotope dilution ultraperformance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry. The hazard index (HI) was calculated on the basis of estimated daily exposure dose and acceptable daily intakes. A total of 16 antibiotics were found in urine, with detection frequencies between 0.2 and 16.0%. Antibiotics were overall detected in 41.6% of urine, and two or more antibiotics were detected in 13.1% of urine. Ciprofloxacin, ofloxacin, and trimethoprim were most frequently detected in urine, with detection frequencies between 10 and 20%. The majority of the antibiotics tested had an estimated daily exposure dose less than 1 µg/kg/day, and 4.3% of pregnant women had a HI value of more than 1. These findings indicated that pregnant women were frequently exposed to antibiotics and some individuals were in the potential risk of adverse microbiological effects induced by antibiotics.

[Related factors for early-onset type 2 diabetes mellitus of rural adults in Yuhuan County of Zhejiang Province in 2012].

OBJECTIVE: To explore related factors for early-onset type 2 diabetes mellitus( EOD) in rural Chinese adults. METHODS: Totally, 1695 newly diagnosed cases of type 2 diabetes mellitus( T2DM) were recruited from baseline survey of Yuhuan Rural Adults Cohort for Diabetes during June to December 2012 in Yuhuan County, Zhejiang Province, China, and divided into EOD or late-onset type 2 diabetes mellitus( LOD) with their diagnosis age at ≤ 40 or > 40 years, respectively. Diagnosis age was compared among different characteristics. Logistic regression was used to analyze related factors in EOD. RESULTS: Among 1695 new T2 DM cases, near half( 47. 3%) were men and 85( 5. 0%) were grouped into EOD. Their mean age at diagnosis of T2 DM was( 60. 39 ±12. 49) years overall. Men or those with more than 9 education years, family average personal income ≥2000 Yuan per month, less occupational physical activities, smoking, drinking, overweight and family history of T2 DM had lower average age at diagnosis than women or those without them, while those with regular physical exercise had higher that than those without that. After the adjustment for other covariates, multiple logistic regression showed that more than 9 education years( OR = 6. 62, 95% CI 3. 87-11. 32), family average personal income ≥2000 Yuan per month( OR = 6. 60, 95% CI 3. 32-13. 12), and regular physical exercise( OR = 0. 37, 95% CI 0. 17-0. 80) were independently correlated to EOD. CONCLUSION: Education level, income, and regular exercise are significantly correlated to EOD in rural Chinese adults.

[Prevalence and change of type 2 diabetes mellitus among rural adults in Deqing County, Zhejiang Province in China during 2006-2014].

OBJECTIVE: To describe the prevalence of type 2 diabetes mellitus( T2 DM) in rural Deqing County, Zhejiang Province, and explore its risk factors. METHODS: Random cluster sampling was used to select 8 rural communities in Deqing County, Zhejiang Province, and a cross-sectional survey was conducted in 2006-2008, 2011-2012 and 2013-2014, respectively. Totally, 6562 eligible subjects were investigated in 2006-2008, 11 763 eligible subjects in 2011-2012, and 10 904 eligible subjects in 2013-2014. Data on demography, life style and disease history, and physical examination such as height, weight and blood pressure were collected. Also, fasting plasma glucose was tested. T2 DM was defined as who having fasting plasma glucose ≥7. 0 mmol/L or was diagnosed by doctors or receiving diabetic treatment. RESULTS: In 2006-2008, 2011-2012 and 2013-2014, the standardized prevalences of T2 DM were 1. 2%, 1. 6% and 2. 1% and those of impaired fasting glucose( IFG) were 7. 2%, 18. 7% and22. 8%, respectively. There were increasing trends over years for both. After adjustment for other covariates in logistic regression, age( compared with age between 18 to 39. 9 years old: aOR_(40-59. 9)= 5. 20, 95% CI 2. 74-9. 89; aOR_(60-)= 8. 02, 95% CI 4. 19-15. 35), female( aOR = 1. 23, 95% CI 1. 02-1. 49), family history of T2 DM( aOR =4. 86, 95% CI 3. 49-6. 77), overweight/obesity( overweight: aOR = 1. 88, 95% CI1. 61-2. 20; obesity: aOR = 5. 10, 95% CI 4. 06-6. 41), hypertension( aOR = 2. 84, 95% CI 2. 44-3. 31), having meat mainly( aOR = 2. 25, 95% CI 1. 89-2. 69) and tea drinking( aOR = 0. 81, 95% CI 0. 68-0. 95) were significantly correlated with T2 DM. CONCLUSION: The prevalence of T2 DM increased over time in rural Deqing County, China. Age, gender, family history of T2 DM, overweight or obesity, hypertension, diet and drinking tea were significantly related to T2 DM.

Antibiotics in Drinking Water in Shanghai and Their Contribution to Antibiotic Exposure of School Children.

A variety of antibiotics have been found in aquatic environments, but antibiotics in drinking water and their contribution to antibiotic exposure in human are not well-explored. For this, representative drinking water samples and 530 urine samples from schoolchildren were selected in Shanghai, and 21 common antibiotics (five macrolides, two ß-lactams, three tetracyclines, four fluoquinolones, four sulfonamides, and three phenicols) were measured in water samples and urines by isotope dilution two-dimensional ultraperformance liquid chromatography coupled with high-resolution quadrupole time-of-flight mass spectrometry. Drinking water included 46 terminal tap water samples from different spots in the distribution system of the city, 45 bottled water samples from 14 common brands, and eight barreled water samples of different brands. Of 21 antibiotics, only florfenicol and thiamphenicol were found in tap water, with the median concentrations of 0.0089 ng/mL and 0.0064 ng/mL, respectively; only florfenicol was found in three bottled water samples from a same brand, with the concentrations ranging from 0.00060 to 0.0010 ng/mL; no antibiotics were found in barreled water. In contrast, besides florfenicol and thiamphenicol, an additional 17 antibiotics were detected in urine samples, and the total daily exposure doses and detection frequencies of florfenicol and thiamphenicol based on urine samples were significantly and substantially higher than their predicted daily exposure doses and detection frequencies from drinking water by Monte Carlo Simulation. These data indicated that drinking water was contaminated by some antibiotics in Shanghai, but played a limited role in antibiotic exposure of children.
