Relationships between Maternal Folic Acid Supplementation and GATA4 Gene Polymorphisms in Patients with Non-Chromosomal Congenital Heart Disease: A Hospital-Based Case-Control Study in China.

This study aimed to investigate the relationships between maternal FA supplementation and nine single-nucleotide variants of the GATA4 gene in non-chromosomal CHD and further explore the gene-environment interactions associated with CHD. A total of 585 CHD patients and 600 controls were recruited in the case-control study. Maternal FA (FA-containing multivitamin) supplementation information and nine polymorphisms of the GATA4 gene were collected in this study. Adjusted ORs (aOR) and their 95% confidence intervals (CIs) were calculated using proper statistical methods to analyze the relationships between the two main exposures of interest with respect to CHD. After adjusting the suspicious confounding factors, a significantly increased risk for CHD in offspring was found with non-FA supplementation before/during the pregnancy to CHD in offspring (aOR = 1.58, 95% CI: 1.01-2.48). We suggested taking FA supplementation before/during the pregnancy to prevent CHD in offspring, especially in the preconception period (aOR = 0.53, 95% CI: 0.32-0.90). The genetic results showed that the polymorphisms of rs4841588, rs12458, and rs904018 under specific genotypes and genetic models were significantly related to CHD. The gene-environment interaction between rs10108052 and FA supplementation before/during pregnancy could increase the risk of CHD (aOR = 5.38, 95% CI: 1.67-17.09, Pinteraction = 0.004). Relationships between maternal FA supplementation and specific polymorphisms of the GATA4 gene, as well as the gene-environment interaction, were significantly associated with CHD in offspring.

Association of MTR gene polymorphisms with the occurrence of non-syndromic congenital heart disease: a case-control study.

To exhaustively explore the association of infant genetic polymorphisms of methionine synthase (MTR) gene with the risk of non-syndromic congenital heart disease (CHD). A hospital-based case-control study involving 620 CHD cases and 620 health controls was conducted from November 2017 to March 2020. Eighteen SNPs were detected and analyzed. Our date suggested that the genetic polymorphisms of MTR gene at rs1805087 (GG vs. AA: aOR = 6.85, 95% CI 2.94-15.96; the dominant model: aOR = 1.77, 95% CI 1.35-2.32; the recessive model: aOR = 6.26, 95% CI 2.69-14.54; the addictive model: aOR = 1.81, 95% CI 1.44-2.29) and rs2275565 (GT vs. GG: aOR = 1.52, 95% CI 1.15-1.20; TT vs. GG: aOR = 4.93, 95% CI 1.93-12.58; the dominant model: aOR = 1.66, 95% CI 1.27-2.17; the recessive model: aOR = 4.41, 95% CI 1.73-11.22; the addictive model: aOR = 1.68, 95% CI 1.32-2.13) were significantly associated with the higher risk of CHD. And three haplotypes of G-A-T (involving rs4659724, rs95516 and rs4077829; OR = 5.48, 95% CI 2.58-11.66), G-C-A-T-T-G (involving rs2275565, rs1266164, rs2229276, rs4659743, rs3820571 and rs1050993; OR = 0.78, 95% CI 0.63-0.97) and T-C-A-T-T-G (involving rs2275565, rs1266164, rs2229276, rs4659743, rs3820571 and rs1050993; OR = 1.60, 95% CI 1.26-2.04) were observed to be significantly associated with risk of CHD. Our study found that genetic polymorphisms of MTR gene at rs1805087 and rs2275565 were significantly associated with higher risk of CHD. Additionally, our study revealed a significant association of three haplotypes with risk of CHD. However, the limitations in this study should be carefully taken into account. In the future, more specific studies in different ethnic populations are required to refine and confirm our findings.Trial registration: Registration number: ChiCTR1800016635; Date of first registration: 14/06/2018.

Trajectory of the development of caries in the permanent dentition of 12- to 16-year-old students based on a latent class growth model analysis in Liuyang / 口腔疾病防治

Objective@# To explore the trajectory of the development of permanent caries in 12- to 16-year-old students in Liuyang and to provide a reference for the prevention and management of caries.@*Methods@#Primary and secondary school students who were registered within the Liuyang jurisdiction were screened for caries from September to November by the Liuyang Center for Disease Control and Prevention. A total of 7 297 students between the ages of 12 and 16 years with complete permanent dentition caries monitoring records and traceable deciduous dentition caries monitoring records were selected from 2013 to 2019, and a zero-inflated negative binomial-latent class growth model (ZINB-LCGM) was established to describe the trajectory of the development of individual caries using the decayed missing filled teeth (DMFT) indicators. @*Results@# DMFT of 12- to 16-year-old students in Liuyang were mainly decayed teeth (DT), with the majority occurring in the first permanent molar. According to the ZINB-LCGM model, the students were classified into three latent categories, "slow growth pattern" (28.55%), "rapid growth pattern" (6.59%), and "stable pattern" (64.86%), which followed different nonlinear caries growth trajectories. Females with deciduous teeth caries were more likely to have trajectories showing a “rapid growth pattern” and a “slow growth pattern”. There were significant differences in the trajectories between men and women, as well as between those with and without primary dentition caries. @*Conclusion @# The trajectory of the development of caries in 12-16-year-old students shows heterogeneity in terms of different developmental patterns of latent categories, suggesting that females with deciduous dental caries should receive more attention.

Factors influencing the hospitalization cost for stroke patients in J district, Shanghai. / 上海市JåŒºè„‘å’ä¸­æ‚£è€ ä½é™¢è´¹ç”¨çš„å½±å“å› ç´ .

OBJECTIVES: Stroke is the main cause of death in Chinese residents, bringing a heavy economic burden to patients. This study aims to explore the characteristics and the factors influencing the hospitalization cost for stroke, and to provide scientific evidence for reducing the economic burden on stroke patients. METHODS: The data were mainly obtained from the Shanghai Statistics Center for Health. Using the coding system of International Classification of Diseases (ICD)-10, we retrospectively collected the stroke-related first hospitalization records of stroke patients in J district, Shanghai during January 1, 2016 to December 31, 2019 whose main diagnostic disease codes were I61-I63. After cleaning and arranging the data, we counted the first hospitalization cost and length of hospital stay (LOS) of the patients. Univariate analysis was performed using non-parametric tests, and the factors influencing stroke hospitalization cost were further analyzed by multiple linear regression fitting path model. RESULTS: A total of 3 901 stroke patients were included. Ischemic and hemorrhagic stroke patients accounted for 92.59% and 7.41%, respectively, of which the mean hospitalization cost per patient were 12 397.35 yuan and 28 814.72 yuan, respectively, and the mean LOS per patient were 13 days and 19 days, respectively. Hospitalization cost for ischemic stroke mainly consisted of medicine fees, diagnosis fees, and service fees, accounting for 44.70%, 29.92%, and 15.42%, respectively, and hospitalization cost for hemorrhagic stroke mainly consisted of medicine fees, diagnosis fees, consumables fees, and service fees, accounting for 38.76%, 18.33%, 17.59%, and 15.38%, respectively. From 2016 to 2019, the proportion of medicine fees for ischemic stroke was decreased by 19.38 percentage points, and the diagnosis fees and service fees were increased by 8.43 percentage points and 9.04 percentage points, respectively; the proportions of medicine fees and consumables fees for hemorrhagic stroke were decreased by 7.54 percentage points and 13.43 percentage points, respectively, and the proportions of diagnostic fees and service fees were increased by 6.87 percentage points and 10.15 percentage points, respectively. Path analysis results showed that the main direct factors influencing hospitalization cost were the LOS, hospital level, operation, and year, and the main indirect factors were age and hospital level (all P<0.05). CONCLUSIONS: The cost burden of stroke patients in Shanghai is relatively heavy, and we should continue to promote the medical reform policy and consolidate the achievements of medical reform. Hospitals should strengthen clinical pathway management and patient health education to improve medical efficiency and reduce invalid hospitalization days. Government departments should continue to improve the medical insurance system, enhance the supervision to medical insurance, and promote health equity.

Identify the Prognostic and Immune Profile of VSIR in the Tumor Microenvironment: A Pan-Cancer Analysis.

VSIR is a critical immunomodulatory receptor that inhibits T cell effector function and maintains peripheral tolerance. However, the mechanism by which VSIR participates in tumor immunity in the pan-cancer tumor microenvironment remains unclear. This study systematically explored the prognostic and immune profile of VSIR in the tumor microenvironment of 33 cancers. We compared the expression patterns and molecular features of VSIR in the normal and cancer samples both from the public databases and tumor chips. VSIR level was significantly related to patients' prognosis and could be a promising predictor in many tumor types, such as GBM, KIRC, SKCM, READ, and PRAD. Elevated VSIR was closely correlated with infiltrated inflammatory cells, neoantigens expression, MSI, TMB, and classical immune checkpoints in the tumor microenvironment. Enrichment signaling pathways analysis indicated VSIR was involved in several immune-related pathways such as activation, proliferation, and migration of fibroblast, T cell, mast cell, macrophages, and foam cell. In addition, VSIR was found to widely express on cancer cells, fibroblasts, macrophages, and T cells in many tumor types based on the single-cell sequencing analysis and co-express with M2 macrophage markers CD68, CD163 based on the immunofluorescence staining. Finally, we predicted the sensitive drugs targeting VSIR and the immunotherapeutic value of VSIR. In sum, VSIR levels strongly correlated with the clinical outcome and tumor immunity in multiple cancer types. Therefore, therapeutic strategies targeting VSIR in the tumor microenvironment may be valuable tools for cancer immunotherapy.

Determinants for Perinatal Mortality in South China: A Prospective Cohort Study.

Objective: To estimate the association of selected maternal and fetal characteristics with the risk of perinatal mortality in South China. Methods: A prospective cohort study was conducted from March 2013 to December 2019. The exposures of interest were maternal sociodemographic characteristics, lifestyle and habits during early pregnancy, and complications of pregnancy. Their effects on the development of perinatal death were analyzed in our study. Results: A total of 44,048 eligible pregnant women were included in the analysis. Of these, 596 fetuses were perinatal deaths (perinatal mortality was 13.5 per 1,000 births). After adjustment, maternal obesity, being employed, history of gestational hypertension, taking antidepressants during early pregnancy, history of gestational diabetes mellitus, gestational diabetes mellitus, infertility drug treatment and assisted reproductive techniques, history of neonatal death, preterm birth, and congenital malformations all significantly increased the risk of perinatal death. Ethnic minority, income > 5,000, multiparous women, and cesarean section associated with reduced risk of perinatal death. Conclusion: Some factors of maternal sociodemographic characteristics, abnormal pregnancy history, lifestyle and habits during early pregnancy, and complications of pregnancy were associated with the risk of perinatal death.

Gender of infant and risk of postpartum depression: a meta-analysis based on cohort and case-control studies.

BACKGROUND: It is inconclusive nowadays for the association between infant's gender and their mothers' risk of developing postpartum depression (PPD). In addition, a complete overview is missing. A meta-analysis of cohort and case-control studies was performed to address the question of whether women who gave birth to a female infant were at an increased risk of developing PPD, compared with those giving birth to a male infant. METHODS: Unrestricted searches were conducted, with an end date parameter of 31 January 2018, of PubMed, Embase, Google Scholar, Cochrane Libraries, and Chinese databases, to identify studies that met pre-stated inclusion criteria. Reference lists of retrieved articles were also reviewed. Either a fixed- or a random-effects model was used to calculate the overall combined risk estimates. RESULTS: Twenty-three studies involving 119,736 women were included for analysis. Overall, mothers who gave birth to a female infant experienced a significantly increased risk of developing PPD compared with the reference group (OR = 1.15, 95%CI: 1.01-1.31; p = .03). However, substantial heterogeneity (p < .00001; I2 = 75%) was observed across studies. Relevant heterogeneity moderators have been identified by subgroup analysis. Sensitivity analysis yielded consistent results. No evidence of publication bias was observed. CONCLUSIONS: Although the role of potential bias and evidence of heterogeneity should be carefully evaluated, the present study suggests women giving birth to a girl are associated with a higher risk of developing PPD when compared with those giving birth to a boy. Improving family and social communication and reducing gender preference should be important components of any such interventions.Statement of significanceProblem or issue Interestingly, the known risk factors leading to PPD are basically the same in different regions and cultures, but the gender of the infant seems to be an exception.What is already known Some studies conducted in traditional western countries indicated that there is a weak or null association between infant's gender and risk of PPD, while others suggested a positive association. In contrast, studies conducted in Nigeria, India, Turkey and China showed that mothers giving birth to a female infant were at a higher risk of developing PPD.What this paper adds Today, the association between infant's gender and risk of developing postpartum depression (PPD) is still uncertain; additionally, a complete overview is missing. Our study represents the first meta-analysis of risk of PPD associated with infant's gender.

Association of maternal dietary habits and ADIPOQ gene polymorphisms with the risk of congenital heart defects in offspring: a hospital-based case-control study.

OBJECTIVES: To estimate the association of maternal ADIPOQ gene, dietary habits in early pregnancy, and their interactions with the risk of congenital heart defects (CHDs) in offspring. METHODS: A case-control study of 464 mothers of CHDs children and 504 mothers of healthy children was included. Maternal dietary habits and genetic polymorphisms of ADIPOQ were the main exposure of interest. Their independent effects and interactions in the development of CHDs were analyzed in our study. RESULTS: The excessive consumption of pickled vegetables (aOR = 1.58, 95%CI: 1.17-2.12), smoked foods (aOR = 1.84, 95%CI:1.34-2.52), barbecued foods (aOR = 1.62, 95%CI: 1.09-2.39), fish and shrimp (aOR = 0.37, 95%CI: 0.27-50), and milk products (aOR = 0.64, 95%CI: 0.51-80) had a significant association with total CHDs risk. The polymorphisms of ADIPOQ gene at rs1501299 (T/T vs G/G: aOR = 0.27, 95%CI: 0.14-50; G/T vs G/G: aOR = 0.67, 95%CI: 0.46-98) and rs2241766 (G/G vs T/T: aOR = 4.35, 95%CI: 2.23-8.51; T/G vs T/T: aOR = 2.23, 95%CI: 1.51-3.28) showed a significant association with total CHDs risk. Likewise, our results found that maternal dietary habits and ADIPOQ genetic variants also were significantly related to the risk of specific CHDs phenotypes. In addition, gene-diet interaction revealed significant associations between the ADIPOQ gene and maternal dietary habits with total CHDs. CONCLUSIONS: Maternal dietary habits, ADIPOQ gene, and their interactions show a significant association with the risk of CHDs. However, our study has some limitations, thus our findings need to be taken with caution, which highlights that more studies are required to further corroborate our findings.

Cost-effectiveness of Morse Fall Scale assessment in fall prevention care in hospitalized patients. / Morseè·Œå€’é‡è¡¨è¯„ä¼°åœ¨ä½é™¢æ‚£è€ é˜²è·Œå€’æŠ¤ç†ä¸­çš„æˆæœ¬æ•ˆæžœ.

OBJECTIVES: To analyze the cost-effectiveness of the Morse Fall Scale by clinical big data for nurses in the prevention of falls in hospitalized patients. METHODS: A total of 59 358 hospitalized patients, who came from the Third Xiangya Hospital of Central South University in 1 year before nurses were trained by the Morse Fall Scale, served as a control, including 26 862 males and 32 496 females. While the 66 203 hospitalized patients served as an observation group in 1 year after nurses were trained by the Morse Fall Scale, including 29 881 males and 36 322 females. The time spent by clinical nurses in the fall-risk assessment and the fall number were recorded in the 2 groups, and the relationship was analyzed between the Morse Fall Scale assessment and the clinical ending along with the labor cost of nursing. The cost-effectiveness was analyzed. In addition, the incidence of fall in the observation group was compared between the falling high-risk patients and the non-high-risk patients. RESULTS: The Morse Fall Scale showed that the incidences of fall in the observation group and the control group were 3.39/100 000 and 3.82/100 000,respectively, there was no significant difference between the 2 groups (U=0.807, P>0.05); the injury rates of falls of Grade 2 and above in the observation group and the control group were 27.30% and 20.00%, respectively, with no significant difference (χ2=0.345, P>0.05); but the labor cost was increased by 130 641.82 Chinses Yuan, and the incremental cost-effectiveness ratio was 43 547.27. However, the incidence of fall was significant higher in the falling high-risk patients by the assessment of the Morse Fall Scale than that in the non-high-risk patients (U=2.941, P<0.05). CONCLUSIONS: The evaluation of the Morse Fall Scale has a certain effect, but it is limited in the prevention of falls in adult hospitalized patients, and the cost-effectiveness analysis is not good. It is recommended to implement the intervention measures for high-risk patients after the assessment, which may improve the management level and efficiency of fall prevention.

Prevalence of diabetes and hypertension and their interaction effects on cardio-cerebrovascular diseases: a cross-sectional study.

BACKGROUND: Hypertension and diabetes mellitus are two of the major risk factors for cardio-cerebrovascular diseases (CVDs). Although prior studies have confirmed that the coexistence of the two can markedly increase the risk of CVDs, few studies investigated whether potential interaction effects of hypertension and diabetes can result in greater cardio-cerebrovascular damage. We aimed to investigate the prevalence of hypertension and diabetes and whether they both affect synergistically the risk of CVDs. METHODS: A cross-sectional study was conducted by using a multistage stratified random sampling among communities in Changsha City, Hunan Province. Study participants aged > = 18 years were asked to complete questionnaires and physical examinations. Multivariate logistic regression models were performed to evaluate the association of diabetes, hypertension, and their multiplicative interaction with CVDs with adjustment for potential confounders. We also evaluated additive interaction with the relative excess risk ratio (RERI), attribution percentage (AP), synergy index (SI). RESULTS: A total of 14,422 participants aged 18-98 years were collected (men = 5827, 40.7%). The prevalence was 22.7% for hypertension, 7.0% for diabetes, and 3.8% for diabetes with hypertension complication, respectively. Older age, women, higher educational level, unmarried status, obesity (central obesity) were associated with increased risk of hypertension and diabetes. We did not find significant multiplicative interaction of diabetes and hypertension on CVDs, but observed a synergistic additive interaction on coronary heart disease (SI, 1.43; 95% CI, 1.03-1.97; RERI, 1.94; 95% CI, 0.05-3.83; AP, 0.26; 95% CI, 0.06-0.46). CONCLUSIONS: Diabetes and hypertension were found to be associated with a significantly increased risk of CVDs and a significant synergistic additive interaction of diabetes and hypertension on coronary heart disease was observed. Participants who were old, women, highly educated, unmarried, obese (central obese) had increased risk of diabetes and hypertension.

Association and interaction effect of UCP2 gene polymorphisms and dietary factors with congenital heart diseases in Chinese Han population.

Congenital heart diseases (CHDs) are the most common birth defects and the leading cause of non-infectious deaths in infants, with an unknown etiology. We aimed to assess the association of genetic variations in UCP2 gene, dietary factors, and their interactions with the risk of CHDs in offspring. The hospital-based case-control study included 464 mothers of children with CHDs and 504 mothers of healthy children. The exposures of interest were maternal dietary factors in early pregnancy and UCP2 genetic variants. Logistic regression analyses were used to assess the association and interaction of UCP2 gene and dietary factors with CHDs. Our results found that the polymorphisms of UCP2 gene at rs659366 and rs660339, together with maternal dietary factors including excessive intake of pickled vegetables and smoked foods were associated with increased risks of CHDs in offspring. Regular intake of fresh meat, fish and shrimp, and milk products were associated with lower risks of CHDs in offspring. Besides, positive interaction between the dominant model of rs659366 and excessive intake of pickled vegetables was found in the additive interaction model (RERI = 1.19, P = 0.044). These findings provide the theoretical basis for gene screening and a new clue for the prevention of CHDs in offspring.

Effect of adverse childhood experiences and DNA methylation on male sexual orientation. / 早期负性经历和DNA甲基化对男性性取向的影响.

The causes for male sexual orientation are complicated, which have not yet been clarified. Recent years have witnessed fruitful progress in the field of biology, while the impact of environment has received little attention. Adverse childhood experiences (ACEs), identified as a special environment in the early stage of development, can affect the individual phenotype by DNA methylation. Given the relationships among male sexual orientation, ACEs, and DNA methylation, as well as based on the existing theory, this article proposes the model "ACEs-DNA methylation-male sexual orientation"from the perspective of environment and epigenetics, aiming to provide a theoretical basis for future research.

Association of maternal gut microbiota and plasma metabolism with congenital heart disease in offspring: a multi-omic analysis.

Congenital heart disease (CHD) is the most common congenital disorder diagnosed in newborns. Although lots of related studies have been published, yet the pathogenesis has not been fully elucidated. A growing body of evidence indicates perturbations of the gut microbiota may contribute in a significant way to the development of obesity and diabetes. Given that maternal obesity and diabetes are well-known risk factors for CHD, maternal gut microbiota may be considered as one of the environmental factors involved in the pathogenesis of CHD. The object of this study is to explore the association between maternal gut microbiota and risk of congenital heart disease (CHD) in offspring, as well as the possible mechanisms linking gut microbiota and disease risk. A case-control study was conducted in mothers of infants with CHD (n = 101) and mothers of infants without CHD (n = 95). By applying 16S rRNA gene sequencing and metabolic approaches to 196 stool and plasma samples, we determined microbiome and metabolome profiles in mothers of infants with CHD and controls, and their association with risk of CHD in offspring. The gut microbiome of mothers of infants with CHD was characterized with lower alpha-diversity and distinct overall microbial composition compared with mothers of infants without CHD. A distinct different metabolic profile was found between mothers of infants with CHD and controls. After controlling for the possible confounders, thirty-four bacterial genera and fifty-three plasma metabolites showed distinct abundances between the two groups. The results of the Spearman correlation analyses revealed a great number of significant correlations between the abundant bacterial genera and differentially expressed metabolites. In particular, the genus Bifidobacterium and Streptococcus showed comparable moderate positive correlations with a range of metabolites that involved in lipid metabolism pathway. Our findings suggest that perturbations of maternal gut microbiota and plasma metabolites may be associated with risk of CHD in offspring, and co-variation between microbiota and metabolites may play a part in the linkage between gut microbiota and risk of CHD in offspring.

Male sperm quality and risk of recurrent spontaneous abortion in Chinese couples: A systematic review and meta-analysis.

OBJECTIVE: To assess the association of conventional semen parameters and sperm DNA fragmentation with risk of recurrent spontaneous abortion (RSA). DESIGN: Systematic review and meta-analysis. SETTING: Not applicable. PATIENTS: Total 1,690 male partners of women with RSA, and 1,337 male partners of fertile control women. INTERVENTIONS: Case-control or cohort studies were determined by searching PubMed, Google Scholar, Cochrane Libraries, China Biology Medicine disc, Chinese Scientific Journals Fulltext Database, China National Knowledge Infrastructure, and Wanfang Database. RSA was defined as two or more previous pregnancy losses. The fertile women refer to the reproductive women who have had at least a normal pregnancy history and no history of abortion. MAIN OUTCOME MEASURES: This study included eight outcome measures: semen volume(ml), semen pH value, sperm density(106/ml), sperm viability (%), sperm progressive motility rate (%), normal sperm morphology rate (%), sperm deformity rate(%), sperm DNA fragmentation index (DFI) (%). The summary measures were reported as standardized mean difference (SMD) with 95% confidence interval (CI). RESULTS: Finally, twenty-four studies were included for analysis. Overall, male partners of women with RSA had a significantly lower level of sperm density (SMD = -0.53, 95%CI: - 0.75 to -0.30), sperm viability (SMD = -1.03, 95%CI: - 1.52 to -0.54), sperm progressive motility rate (SMD = -0.76, 95%CI:-1.06 - -0.46), and normal sperm morphology rate (SMD =  -0.56, 95%CI: - 0.99 to -0.12), and had a significantly higher rate of sperm deformity rate (SMD = 1.29, 95%CI: 0.60 - 1.97), and sperm DFI (SMD = 1.60, 95%CI: 1.04 to 2.17), when compared with the reference group. However, there were no statistically significant differences for semen volume (SMD = -0.03, 95%CI: -0.14 - 0.08) and semen pH value (SMD =  -0.23, 95% CI: -0.50 to 0.05) among 2 groups. CONCLUSIONS: The results of this analysis support an association of sperm density, sperm viability, sperm progressive motility rate, normal sperm morphology rate, sperm deformity rate, as well as sperm DFI with RSA. However, given the significant heterogeneity between studies and the lack of more detailed data on the subjects, further large-scale prospective studies are needed.

Association of maternal dietary intakes and CBS gene polymorphisms with congenital heart disease in offspring.

BACKGROUND: Although it is generally acknowledged that genetic and environmental factors are associated with risk of congenital heart disease (CHD), the causes are not fully understood. This study aimed at assessing the association of maternal dietary intakes, genetic variants of cystathionine beta synthase (CBS) gene and their interactions with risk of CHDs in offspring. METHOD: A hospital-based case-control study of 464 mothers with CHD infants and 504 control mothers of health infant was performed. The exposures of interest were maternal dietary intakes in early pregnancy, single nucleotide polymorphisms (SNPs) of CBS gene. RESULTS: More frequent intake of pickled vegetables (adjusted odds ratio[aOR] = 1.81; 95% confidence interval[CI]: 1.38-2.37), smoked foods (aOR = 2.00; 95%CI: 1.53-2.60), barbecued foods (aOR = 1.63; 95%CI: 1.19-2.25) and fried foods (aOR = 1.57; 95%CI: 1.22-2.03) were associated with higher risk of CHD, while salted eggs (aOR = 0.20; 95%CI: 0.12-0.33), fish and shrimp (aOR = 0.34; 95%CI: 0.27-0.44), fresh fruits (aOR = 0.49; 95%CI: 0.37-0.66), and milk products (aOR = 0.54; 95%CI: 0.45-0.65) were associated with lower risk of CHD. The SNPs of CBS gene at rs2851391 (T/T vs C/C: aOR = 1.91, 95%CI: 1.15-3.15) and rs234714 (T/T vs C/C: aOR = 2.22, 95%CI: 1.32-3.73) significantly increased the risk of CHD. Additionally, significant interaction effects between maternal dietary intakes and CBS genetic variants on CHD risks were observed. CONCLUSIONS: Maternal dietary factors, CBS genetic variants and their interactions were significantly associated with risk of CHD in offspring. However, it is still unclear how these factors jointly work in the development of CHD, and more studies with larger samples and prospective design are required.

Reported prevalence of depression or depressive symptoms among men who have sex with men in China, 2004-2018: A systematic review and meta-analysis.

BACKGROUND: Depression is a major mental disorder that imposes a considerable burden on health. Men who have sex with men (MSM) are at high risk for depression. Numerous studies have reported the prevalence of depression or depressive symptoms among MSM in China. However, the estimates have varied substantially between studies. This meta-analysis aimed to establish the pooled prevalence of depression or depressive symptoms among Chinese MSM to attract public attention. METHOD: A systematic search of several electronic databases and a subsequent manual search was performed to identify relevant studies. A random effects model was adopted to calculate the pooled prevalence of depression or depressive symptoms. Heterogeneity between studies and publication bias was also assessed. RESULTS: A total of 54 articles with a sample size of 21,950 MSM were analysed. The pooled prevalence of depression or depressive symptoms among MSM was 40.0% (95% CI: 37.9%-45.0%). Substantial heterogeneity was observed across individual studies. The pooled summary estimate stratified by screening instruments and cutoff scores ranged from 19.0% to 60.2%. Subgroup analysis indicated that survey dates, sampling method, HIV infection status and occupation can partially contribute to the between-study heterogeneity. LIMITATIONS: The findings should be interpreted with caution because of several limitations related to the heterogeneity across studies, sampling method and quality assessment. CONCLUSIONS: Overall, the reported prevalence of depression or depressive symptoms among Chinese MSM was fairly high. The study suggested that more attention and effective intervention programmes are urgently provided to prevent and improve mental health issues among Chinese MSM.

The efficacy of L-carnitine in improving malnutrition in patients on maintenance hemodialysis: a meta-analysis.

The improvement of malnutrition with levocarnitine in maintenance hemodialysis (MHD) patients is controversial. We performed a meta-analysis to evaluate the efficacy of levocarnitine in improving malnutrition in MHD patients. We performed a literature search for relevant articles related to the treatment of malnutrition by L-carnitine in MHD patients in PubMed, Embase, Web of Science, China National Knowledge Infrastructure, and Wanfang databases. We set the publication dates from 1950 to July 2019. The levels of albumin, prealbumin, total protein, and transferrin before and after treatment were used for assessing malnutrition. Twenty-seven studies were included in the present analysis. The results of the random effects model indicated that L-carnitine treatment improved the albumin level in patients on MHD patients. The pooled standardized mean difference of albumin level was 2.51 (95% confidence interval (CI): 2.13-2.90, P<0.001). The pooled total protein level was 3.83 (95% CI: 2.41-5.24, P = 0.000) and the pooled transferrin level was 0.35 (95% CI: 0.18-0.52, P = 0.000). Significant differences were observed with the total protein and transferrin levels. The results indicated that levocarnitine significantly improved the prealbumin level in patients on MHD. The pooled prealbumin level was 70.86 (95% CI: 42.99-98.73, P = 0.000). No publication bias was detected (P>0.05). The present meta-analysis indicated that L-carnitine can have a favorable effect on malnutrition biomarkers in patients on MHD, including the increase in albumin, total protein, transferrin, and prealbumin levels. The L-carnitine could be an option for treatment of MHD patients.

Birth prevalence of congenital heart disease in China, 1980-2019: a systematic review and meta-analysis of 617 studies.

To assess the birth prevalence and spatial distribution of congenital heart disease (CHD) in China by conducting a complete overview and using spatial epidemiological methods. Unrestricted searches were conducted on seven electronic databases, with an end-date parameter of May 2019. Data on the birth prevalence of CHD and its subtypes were collected and combined using either the random-effect model or fixed-effect model. Subgroup sensitivity analyses were performed to explore potential heterogeneity moderators. The three-dimensional trend analysis and a visualization of CHD birth prevalence among different provinces were performed to describe the spatial distribution characteristics. Total 617 studies involving 76,961,354 births and 201,934 CHD individuals were included. Overall, total CHD birth prevalence increased continuously over time, from 0.201‰ in 1980-1984 to 4.905‰ in 2015-2019. The study on the high-income provinces, population-based monitoring model, male births, and urban regions reported a significantly higher prevalence of total CHD compared with upper-middle-income provinces, hospital-based monitoring model, female births, and rural regions, respectively. National CHD birth prevalence increased gradually from western region to eastern region, but decreased gradually from southern to northern region. Relevant heterogeneity moderators including gender, geographic region, income levels, and monitoring models have been identified by subgroup analyses. Sensitivity analysis yielded consistent results. Total CHD birth prevalence in China increases continuously in the past 40 years. Significant differences in gender, geographical regions, income levels, and monitoring models were found. In the future, population wide prospective birth defect registries covering the entire Chinese population need to determine the exact birth prevalence.

Associations of sexually transmitted infections and bacterial vaginosis with abnormal cervical cytology: A cross-sectional survey with 9090 community women in China.

BACKGROUND: Although it is well acknowledged that persistent infection with high-risk human papillomavirus types in genital sites plays a crucial role in the development of squamous cell cervical carcinoma, there is no unanimous consensus on the association between non-HPV sexually transmitted infections and abnormal cervical cytology. METHODS: In the present study, we evaluated cervical cytology status, sexually transmitted infections and bacterial vaginosis status, and collected social-demographic information among recruited participants to explore the association of STIs and bacterial vaginosis with abnormal cervical cytology. RESULTS: 9,090 women's specimens were successfully tested, with a total of 8,733 (96.1%) women had normal cytology and 357 (3.9%) women exhibited abnormal cytology. The prevalence of HPV, Chlamydia trachomatis, Neisseria gonorrhoeae, and bacterial vaginosis was significantly higher in the ≥ASC-US group than the NILM group (P<0.05). Women with Neisseria gonorrhoeae infection (AOR = 5.30, 95% CIs = 1.30-21.51, P = 0.020) or bacterial vaginosis (AOR = 1.94, 95% CIs = 1.08-3.47, P = 0.026) exhibited an increased risk of abnormal cervical cytology after adjusted for carcinogenic HPV-positive status. CONCLUSIONS: Our results demonstrated that Neisseria gonorrhoeae infection in genital sites and/or bacterial vaginosis may independently increase the risk for cervical cytology abnormalities after adjusted for carcinogenic HPV-positive status. Besides, these results improved our understanding of the etiology of abnormal cervical cytology and may be useful for the management of women with ASC-US cytology.
