ABSTRACT

Objective: To investigate the associations between adverse childhood experiences (ACE) and substance use behaviors among lesbians to provide a scientific basis for high-risk population identification and formulation of targeted intervention measures. Methods: Lesbians who participated in routine AIDS voluntary counseling, testing services, activities, and peer recommendations were recruited from July to December 2018, with the help of LesPark in Beijing. Convenient sampling method was used. Demographic characteristics, ACE, and substance use behaviors of subjects were investigated using an online platform powered by www.wjx.cn. Subsequently, the associations between ACE and adulthood substance use behaviors were evaluated using the logistic regression model. The SPSS 22.0 was used for statistical analysis. Results: A total of 294 lesbians were recruited in the study, 81.3% (239/294) of them were lesbians, and 18.7% (55/294) were bisexuals. Besides, 55.8% (164/294) of subjects reported they had had ACE, with proportions of lesbians experiencing abuse, neglect, and family dysfunction as 33.3% (98/294), 24.5% (72/294), and 32.7% (96/294), respectively. 55.1% (162/294) of the lesbians reported they had smoked in the past 30 days, 11.2% (33/294) reported having drug-use behavior in the past three months, and 22.8% (67/294) claimed drinking alcohol weekly. Multivariate logistic regression analysis showed that lesbians with ACE were at high risks to smoke (OR=1.87, 95%CI: 1.13-3.08), drink (OR=2.13, 95%CI: 1.18-3.84), and use drugs (OR=3.33, 95%CI: 1.29-8.61) in adulthood. Moreover, lesbians with childhood family dysfunction were at higher risk of smoking cigarettes (OR=2.60, 95%CI: 1.46-4.62) and drinking alcohol (OR=2.65, 95%CI: 1.44-4.87). At the same time, those with abuse experience were at higher risk of drug use (OR=3.17, 95%CI: 1.26-7.96). Conclusions: Substance use behaviors, including cigarette smoking, drinking alcohol, and drugs use, were common among lesbians. Positive associations were found between ACE and adulthood substance use behaviors.

ABSTRACT

Objective: To explore the correlation between alanine aminotransferase (ALT) trajectories and new-onset metabolic fatty liver disease (MAFLD) to provide a scientific basis for the prevention and treatment of MAFLD. Methods: The study cohort was composed of 3 553 subjects who met the inclusion criteria in the cohort study of the Henan physical examination population. According to the ALT levels of the subjects’ physical examination from 2017-2019, three different ALT trajectory groups were determined by R LCTMtools, namely low-stable group, medium-stable group, and high-stable group. The incidence of MAFLD during physical examination in 2020 was followed up, the cumulative incidence rate in each group was calculated by product-limit method, and Cox proportional hazards regression model analyzed the correlation between different ALT trajectories and new-onset MAFLD. Results: The incidence rate of MAFLD parallelly increased with the increase of ALT locus, which was 6.93%, 15.42%, and 19.05%, respectively, and the difference was statistically significant (P<0.001). After adjusting for multiple confounding factors, such as gender, waist circumference, blood pressure, BMI, fasting blood sugar, and blood lipid by Cox proportional hazards regression model, the risks of MAFLD in ALT medium-stable and the high-stable group were still 1.422 times (95%CI:1.115-1.813) and 1.483 times (95%CI:1.040-2.114) of low-stable ALT group (P<0.05). Conclusions: The risk of MAFLD parallelly increases with the increase of ALT level in the normal long-term range. it is necessary to carry out the intervention for MAFLD with long-term average high value to avoid the progress of MAFLD disease to achieve the early prevention on MAFLD.

ABSTRACT

Objective: To explore the impact of activities of daily living (ADL) on depression in the elderly and the role of social networks and children’s support. Methods: Data used in this study were obtained as participants aged 60 and above from the “China Longitudinal Aging Social Survey 2018”,with a sample size of 10 215. ADL, social network and depression were measured on scales. The moderated mediation model was used to analyze the role of social networks and children’s support. The SPSS 25.0 software was used for statistical analysis, the PROCESS 3.3 macro program was used to test the moderated mediation effect. Results: A total of 10 760 participants aged 60 and above were included. Activities of daily living showed a direct impact on depression in the elderly (β=-0.090, P<0.01), with social network playing a mediating role (β=0.035, P<0.01; β=-0.064, P<0.05) and children’s support played a moderating role (β=-0.029, P<0.05) in the relationship between the elderly’s ADL and depression. Conclusions: The social network is an essential buffer to declining ADL’s negative impact on depression of older adults. Children’s support is a powerful supplement to enhance social networks’ positive role and reduce the risk of elderly depression. Exerting the combined advantages of social networks and children’s support are important ways to maintain the elderly’s mental health.

ABSTRACT

Objective: To forecast the burden of chronic obstructive pulmonary disease (COPD) in China by 2030 and evaluate the effectiveness of controlling risk factors based on the predictive model. Methods: Based on the relationship between the death of COPD and exposure to risk factors and the theory of comparative risk assessment, we used the estimates of the Global Burden of Disease Study 2015 (GBD2015) for China, targets for controlling risk factors, and proportion change model to project the number of deaths, standardized mortality rate, and probability of premature mortality from chronic respiratory diseases by 2030 in different scenarios and to evaluate the impact of controlling the included risk factors to the disease burden of COPD in 2030. Results: If the trends in exposure to risk factors from 1990 to 2015 continued, the number of deaths and the mortality for COPD would be 1.06 million and 73.85 per 100 000 population in China by 2030, respectively, with an increase of 15.81% and 10.69% compared to those in 2015. Compared to 2015, the age-standardized mortality rate would decrease by 38.88%, and the premature mortality would reduce by 52.73% by 2030. If the smoking rate and fine particulate matter (PM_2.5) concentration separately achieve their control targets by 2030, there would be 0.34 and 0.27 million deaths that could be avoided compared to the predicted numbers based on the natural trends in exposure to risk factors and the probability of premature death would reduce to 0.59% and 0.52%, respectively. If the control targets of all included risk factors were achieved by 2030, a total of 0.53 million deaths would be averted, and the probability of premature death would decrease to 0.44%. Conclusions: If the exposures to risk factors continued as showed from 1990 to 2015, the number of deaths and mortality for COPD would increase by 2030 compared to 2015, and the standardized mortality and the probability of premature death would decrease significantly, which would achieve the targets of preventing and controlling COPD. If the exposure to the included risk factors all achieved the targets by 2030, the burden of COPD would be reduced, suggesting that the control of tobacco use and air pollution should be enhanced to prevent and control COPD.

ABSTRACT

Objective: To understand the epidemiological characteristics of COVID-19 epidemic in Ejina banner, Inner Mongolia, in October 2021 and provide evidence for the improvement of COVID-19 prevention and control. Methods: The information about the time, area and population distributions of COVID-19 cases in Ejina before November 13, 2021 and the gene sequencing result of the isolates were collected for a statistical descriptive analysis. Results: The first COVID-19 case in Ejina occurred on 7 October, 2021. A total of 164 COVID-19 cases were reported from October 19 to November 12. Most cases were distributed in 6 communities in Darahub (156 cases, 95.12%). The result of full gene sequencing of the isolates indicted that the pathogen was Delta variant (B.1.617.2). The male to female ratio of the cases was 1.3∶1. The age of cases ranged from 1 to 85 years, and the cases aged 20-59 years accounted for 78.66%. The main clinical symptoms were sore throat (91 cases, 91.92%), cough (49 cases, 49.49%) and fever (23 cases, 23.23%). Most cases were ordinary ones (81 cases, 49.39%) and mild ones (68 cases, 41.46%). The cases were mainly detected at the isolation points (84 cases, 51.22%) and through population based nucleic acid testing (62 cases, 37.80%). The basic reproduction number (R₀) of COVID-19 was 5.3, the average incubation period was 3.9 days. The local government rapidly started Ⅳ level emergency response and conducted 10 rounds of nucleic acid tests. The transferring of travelers reduced the risk for the further spread of COVID-19 in Ejina. Conclusions: The epidemic of COVID-19 in Ejina characterized by strong transmission, short incubation period, herd susceptibility and case clustering. Delta variant (B.1.617.2) was the pathogen, which might be imported from Zeke port. Comprehensive prevention and control measures, such as closed-loop management and vaccination, should be continued. The successful transferring of the patients and travelers provided evidence for the effective and precise prevention and control of COVID-19 in a routine manner.

ABSTRACT

Objective: To investigate the association between tea consumption and the risk of all-cause and cause-specific mortality among Chinese adults. Methods: This study was based on China Kadoorie Biobank (CKB). Tea consumption information was self-reported by participants at baseline. Death was mainly identified by linkage to the death registry system. Cox proportional hazard regression models estimated HR and 95%CI. Results: With a median follow-up of 11.1 years, there were 34 661 deaths in 438 443 participants. Compared with those who never drink tea, all-cause mortality HR(95%CI) were 0.89(0.86–0.91) and 0.92(0.88–0.95) for non-daily tea drinkers and daily tea drinkers, respectively. A statistically significant difference was found in the association of tea consumption and the risk of all-cause mortality between men and women(interaction P<0.05). The protective effect was mainly seen in men. Compared with those who never drink tea, daily tea drinkers had a reduced risk of death from ischemic heart disease, ischemic stroke, hemorrhagic stroke, cancer, respiration diseases and other causes of death, and the corresponding HR(95%CI) were 0.83(0.76–0.92), 0.82(0.69–0.97), 0.86(0.78–0.94), 1.03(0.97–1.09), 1.00(0.87–1.16), 0.84(0.78–0.90). Among never smokers and non-excessive drinkers, there was no statistically significant association between daily tea drinking and the risk of death from cancer. While smokers and excessive drinkers had an increased risk of death from cancer (interaction P<0.001). Conclusions: Tea consumers had reduced risks of all-cause mortality and partial cause-specific mortality, but not for the risk of death from cancer. On the contrary, daily tea drinkers with smoking habits and excessive alcohol drinking had an increased risk of death from cancer.

ABSTRACT

Objective: To investigate the expression levels and clinical significance of glioma-associated oncogene homolog 1 (GLI1) and sonic hedgehog signaling molecule (Shh) in the malignant transformation of ovarian endometriosis (EM). Methods: The expressions of GLI1 and Shh were detected by real-time reverse transcription (RT)-polymerase chain reaction (PCR) and EnVision method in 50 cases of ovarian EM tissues, 35 cases of atypical endometriosis (aEM) and 50 cases of endometriosis-associated ovarian cancer (EAOC). The expression differences of two molecular markers in the malignant transformation of ovarian EM were compared, and the relationships between two molecular markers and the clinicopathological features and prognosis of EAOC were analyzed. Results: (1) RT-PCR showed that the expression levels of GLI1 mRNA in EM, aEM and EAOC group were 1.77±0.40, 3.54±0.44, and 7.80±0.24, respectively. The expression levels of Shh mRNA were 0.95±0.21, 3.14±0.35, and 5.41±0.31, respectively. GLI1 and Shh mRNA in EAOC group were significantly higher than those in EM and aEM group (all P<0.01), and there were statistically significant differences between EM and aEM group (all P<0.01). The percentages of GLI1 in ovarian EM, aEM and EAOC were 32% (16/50), 57% (20/35), and 66% (33/50), respectively, meanwhile, the positive expression rates of Shh were 20% (10/50), 49% (17/35), and 54% (27/50), respectively (all P<0.01). GLI1 mRNA expression was positively correlated with Shh mRNA expression in EAOC tissues (r=0.721, P<0.01). The expressions of GLI1 protein were proportionated to Shh protein in EAOC tissues (r=0.608,P=0.001). (2) The expression of GLI1 was significantly related to the International Federation of Gynecology and Obstetrics (FIGO) stage, cancer antigen 125 (CA₁₂₅) levels, lymph node metastasis, and Platinum resistance in EAOC patients (all P<0.05). The expression of Shh were related to FIGO stage and lymph node metastasis in EAOC patients (all P<0.05). Logistic regression analysis showed that GLI1 expression was an independent risk factor for poor prognosis in EAOC patients (P<0.05). Kaplan-meier survival analysis showed that the overall survival rate of EAOC patients with high GLI1 expression and low GLI1 expression was 12.1% and 35.3%, respectively, with statistical significance (χ²=10.73, P<0.01). The overall survival rate of EAOC patients with high and low expression of Shh protein was 11.1% and 30.4%, in which there was statistically significant difference (χ²=3.96, P=0.047). Conclusion: GLI1 and Shh are highly associated with the malignant transformation of ovarian EM, which may play a role in promoting malignant degeneration of ovarian EM, and the high expression of GLI1 and Shh indicates a poor prognosis in EAOC patients.

ABSTRACT

Objective: To explore the expression of long non-coding RNA-myeloid differentiation factor 88 (lnc-MyD88) and its relationship with the prognosis of patients with epithelial ovarian cancer (EOC). Methods: A total of 70 EOC patients who underwent initial cytoreductive surgery and platinum-based drugs combined with paclitaxel for 6 to 8 courses were selected at Sichuan Cancer Hospital from January 2016 to January 2019. The fresh cancer tissue specimens were collected. In addition, 28 fresh normal ovarian tissues from patients who underwent surgery for benign gynecological diseases during the same period were collected as control group. Reverse transcription (RT) and real-time quantitative polymerase chain reaction (qPCR) were used to detect the expression of lnc-MyD88 and myeloid differentiation factor 88 (MyD88) mRNA in EOC tissues and normal ovarian tissues. The correlation between the expression of lnc-MyD88 and MyD88 mRNA in EOC was analyzed by Pearson’s correlation coefficient. The relationship between lnc-MyD88 expression and clinicopathological characteristics of patients with EOC was analyzed. Kaplan-Meier method was used to calculate the survival rate of patients. The log-rank test was used for univariate survival analysis, and Cox proportional hazard model was used for multivariate survival analysis. Results: (1) RT-qPCR showed that the relative expression level of lnc-MyD88 and MyD88 mRNA in EOC were 0.009 (0.000-0.049) and 0.001 (0.000-0.006), respectively, which were significantly higher than those of normal ovarian tissues (all P<0.01); Pearson’s correlation coefficient showed that the expression of lnc-MyD88 and MyD88 mRNA in EOC was positively correlated (r²=0.610, P<0.01). (2) The high expression rate of lnc-MyD88 in EOC patients with lymph node metastasis, distant metastasis and chemotherapy resistance (71%, 64% and 70%, respectively) were significantly higher than the patients in control group (41%, 40% and 35%, respectively; all P<0.05). There were no statistically significant in the high expression rate of lnc-MyD88 in EOC patients with different ages, pathological types, pathological grades, surgical pathological stages, postoperative residual lesion size, and ascites cancer cells (all P>0.05). (3) Univariate analysis showed that surgical pathological staging, lymph node metastasis, distant metastasis, postoperative residual tumor size, and high expression of lnc-MyD88 and MyD88 mRNA significantly affected the progression-free survival (PFS) and overall survival (OS) of EOC patients (all P<0.05), ascites cancer cells were the risk factors that significantly affected PFS in EOC patients (P=0.040); multivariate analysis showed that surgical pathological staging and high expression of lnc-MyD88 and MyD88 mRNA were independent factors affecting PFS and OS in EOC patients (all P<0.05), the size of residual lesions after surgery was an independent factor affecting PFS in EOC patients (P=0.001). Conclusions: The level of lnc-MyD88 expression in ovarian cancer tissues was significantly increased. Lnc-MyD88, as a molecular marker for the poor prognosis of EOC, is related to the expression of MyD88 in EOC, and may be involved in its expression regulation, thereby affecting the survival and prognosis of EOC patients.

ABSTRACT

Objective: To explore the effects of pregnancy complicated with Takayasu arteritis (TA) on maternal and fetal outcomes. Methods: The clinical data of 17 TA patients with pregnancy and finally terminated admitted to the First Affiliated Hospital of Zhengzhou University from January 2012 to December 2020 were collected and the maternal and infant outcomes were retrospectively analyzed. Results: Among the 24 pregnancies in 17 TA patients in our hispital, 11 patients in our hospital were primiparous (46%, 11/24) and 13 patients were multiparous (54%, 13/24); 4 cases of chronic hypertension before pregnancy (17%, 4/24), and 20 cases of non-hypertension (83%, 20/24) were abserved. Apart from the thoracoabdominal artery type, 15 cases (63%, 15/24) of brachiocephalic type, 8 cases (33%, 8/24) of extensive type, and 1 case of pulmonary artery type (4%, 1/24) were included in TA classification; the renal artery was damaged in 7 cases (7/8) of the extensive type. Among the 24 pregnancies of 17 TA patients, 8 cases of pregnancy complications occurred, including 4 cases (17%, 4/24) of preeclampsia, one case of (4%, 1/24) new-onset hypertension during pregnancy, exacerbation of existing hypertension, thrombocytopenia and ischemic stroke respectively; 3 cases of induced abortion, 1 case of induced labor, and 20 cases of final delivery were found. Of the 20 final deliveries, 3 cases (15%, 3/20) were delivered through the vagina; 17 cases (85%, 17/20) were delivered by cesarean section; 3 cases (15%, 3/20) of fetal growth restriction and 6 cases of oligohydramnios (30%, 6/20) were occurred. The median gestational age of pregnancy termination of 17 full-term neonates (85%, 17/20) and 3 premature neonates (15%, 3/20) was 38.4 weeks (range:29.6-40.9 weeks). All premature women were complicated with pre-eclampsia or severe pre-eclampsia, which lead to premature birth; the birth weight of the neonates was (2 791±783) g. Neonatal asphyxia occurred in 3 cases (15%, 3/20), and 6 cases (30%, 6/20) were admitted to the neonatal intensive care unit. None of the newborns died. The patients were followed up for 3 months to 7 years. Except for one case who underwent surgical treatment 3 years after delivery and died of intraoperative hemorrhage, the other 16 patients were in stable condition; all the newborns grew and developed well. The incidences of maternal and infant adverse events were higher in those with chronic hypertension, renal artery involvement, and no use of hormones and aspirin during pregnancy, but the differences were not statistically significant (all P>0.05). Conclusions: Pregnancy with TA has adverse effects on maternal and infant outcomes. To reduce the occurrence of maternal and child adverse events, the condition of TA patients should be fully assessed before pregnancy, multidisciplinary cooperation, regular treatment, strengthened monitoring of the condition, timely treatment of complications, selection of appropriate delivery methods after pregnancy, and vigilance of postpartum complications should be properly carried out.

ABSTRACT

Objective: To evaluate the efficacy and survival outcomes of dose-dense (biweekly) carboplatin plus paclitaxel (PC) as neoadjuvant chemotherapy (NAC) in triple-negative breast cancer (TNBC), and to explore an optimal neoadjuvant chemotherapy regimen for TNBC. Methods: Patients diagnosed as TNBC(cT1-4N0-3M0) in Cancer Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College Between January 2008 and September 2018 who received dose-dense PC and standard 3-weekly PC as NAC were 1∶1 matched using propensity score matching (PSM) to compare the efficacy, safety and survival outcomes. Results: One hundred of TNBC patients were enrolled (50 patients were divided in dose-dense group, 50 patients in standard group). The objective response rate (ORR) of dose-dense group and standard group were both 90.0% (45/50). The grade 3-4 neutropenia in dose-dense group was less than that of standard group (32.7% vs. 68.0%, P=0.001), while the rate of ALT/AST elevation in dose-dense group was higher than that of standard group (57.1% vs. 32.0%, P=0.012). The pathological complete response (pCR) rates were 34.0% (17/50) in dose-dense group and 38.0% (19/50) in standard group, without statistically significance (P=0.677). The median follow-up time was 55 months (3-150 months). The 5-year recurrence-free survival (RFS) in dose-dense group and standard group were 83.5% and 75.2%, respectively the 5-year overall survival (OS) in dose-dense and standard group were 87.9% and 84.5% the difference were not statistically significant (P=0.322 and 0.647, respectively). Patients with residual disease (tumor size≥1 cm or lymph node positive) had poor prognosis, the 5-year RFS and OS were 59.3% and 68.5%, respectively. Conclusions: Dose-dense PC has similar efficacy with standard 3-weekly PC and has a good safety profile. Since dose-dense regimen can shorten the duration of therapy, it can be an alternative in TNBC.
