RESUMO

BACKGROUND: There was a high prevalence of overweight/obesity among patients with severe mental disorders (SMD). However, studies on the lifestyle-based interventions in patients with SMD are limited. OBJECTIVE: To examine the effects of an educational lifestyle intervention on body weight and psychological health among Chinese community-dwelling overweight/obese patients with SMD. METHODS: Community-dwelling overweight/obese patients with SMD was recruited from Shenzhen, China in October 2020. They were randomly allocated into intervention group (IG) and control group (CG). Participants in IG received a 12-month educational lifestyle intervention, while the CG was exposed to routine care. A generalized estimating equation model was used to assess the effect of the intervention over time. RESULTS: A total of 176 subjects (88 in IG and 88 in CG) aged 42.2 ± 10.9 years were included in this study. After adjusting for potential confounders, body weight (p = 0.001), body mass index (BMI, p = 0.001), and waist circumference (p = 0.027) in IG significantly decreased compared with CG after 12 months. Besides, IG had significantly higher life satisfaction than CG after intervention (p = 0.026), whereas significant reductions in depressive symptoms were observed in IG from 26.1 % at baseline to 13.6 % after the intervention (p = 0.027), and the between-group differences were marginally significant (p = 0.086). CONCLUSION: An educational lifestyle intervention can effectively reduce body weight parameters and improve psychological health in overweight/obese patients with SMD.

RESUMO

Patients with schizophrenia or bipolar disorders in community had poor psychosocial functioning, social support, and life satisfaction. However, the interaction effects of social support and depression on life satisfaction remains unclear. Thus, we examined these associations among patients with schizophrenia or bipolar disorder. This cross-sectional study was conducted from October to December 2020 in Shenzhen, China. Information on social support, depression, and life satisfaction was assessed by standardized questionnaires through a face-to-face interview. Hierarchical multiple regression analysis was performed to estimate the associations of social support and depression with life satisfaction and to explore the mediation effect of social support. A total of 293 patients aged 39.7 ±â€…11.1 years (males: 47.1 %) were included in this study. Social support was positively associated with high life satisfaction (explaining 7.2% of the variance), while depression was negatively associated with life satisfaction (explaining 17.8% of the variance). Furthermore, social support mediated 12.5% of the association between depression and life satisfaction. Social support and depression were significantly associated with life satisfaction in patients with schizophrenia or bipolar disorders. Moreover, social support mediated the association between depression and life satisfaction in this population. Health interventions that benefit social support should be promoted to alleviate the negative impact of depression on their life satisfaction.

RESUMO

Objective: To analyze the status of statins use and low-density lipoprotein cholesterol (LDL-C) management in patients with atrial fibrillation (AF) and very high/high risk of atherosclerotic cardiovascular disease (ASCVD) from Chinese Atrial Fibrillation Registry (CAFR). Methods: A total of 9 119 patients with AF were recruited in CAFR between January 1, 2015 to December 31, 2018, patients at very high and high risk of ASCVD were included in this study. Demographics, medical history, cardiovascular risk factors, and laboratory test results were collected. In patients with very high-risk, a threshold of 1.8 mmol/L was used as LDL-C management target and in patients with high risk, a threshold of 2.6 mmol/L was used as LDL-C management target. Statins use and LDL-C compliance rate were analyzed, multiple regression analysis was performed to explore the influencing factors of statins use. Results: 3 833 patients were selected (1 912 (21.0%) in very high risk of ASCVD group and 1 921 (21.1%) in high risk of ASCVD group). The proportion of patients with very high and high risk of ASCVD taking statins was 60.2% (1 151/1 912) and 38.6% (741/1 921), respectively. Attainment rate of LDL-C management target in patients with very high and high risk were 26.7% (511/1 912) and 36.4% (700/1 921), respectively. Conclusion: The proportion of statins use and attainment rate of LDL-C management target are low in AF patients with very high and high risk of ASCVD in this cohort. The comprehensive management in AF patients should be further strengthened, especially the primary prevention of cardiovascular disease in AF patients with very high and high risk of ASCVD.

RESUMO

Objective: This study explored the thromboembolism risk of low-risk atrial fibrillation (AF) patients (CHA2DS2-VASc score of 0 or 1 for male and 1 or 2 for female) with different clinical characteristics to provide the basis for anticoagulation decision-making in these patients. Methods: We prospectively enrolled consecutive 2 862 nonvalvular low-risk AF patients between August 2011 to December 2018 in China-AF (China Atrial Fibrillation Registry) Study, their CHA2DS2-VASc score was 0 or 1 for male and 1 or 2 for female. According to their age, sex, presence or absence of hypertension, diabetes mellitus, congestive heart failure, and vascular disease at the time of enrolling, patients were divided into CHA2DS2-VASc score 0 score group, 1 score group, and 2 score group. Patients were followed up every 6 months by outpatient clinic visit or telephone interview. The outcome was a thromboembolic event, including ischemic stroke and systemic embolism. Univariate Cox regression analysis was used to compare the thromboembolism risk between the patients with different risk factors and CHA2DS2-VASc score 0 group. Results: A total of 2 862 low-risk atrial fibrillation patients were enrolled in this study. 915 patients (32.0%) were female, and age was (55.0±10.7) years old. There were 933 patients (32.6%) in CHA2DS2-VASc score 0 group, 1 401 patients (49.0%) in score 1 group and 528 patients (18.5%) in score 2 group. During follow-up (median 1.5 years, 5 811.82 person-years), 33 cases of thromboembolic events were recorded, the annual rate of thromboembolism was 0.57% (95%CI 0.40%~0.80%). The number of thromboembolic events in patients with CHA2DS2-VASc score 0, 1 and 2 were 8, 11 and 14, respectively, and the annual thromboembolism event rates were 0.40% (95%CI 0.20%-0.81%), 0.39% (95%CI 0.22%-0.71%) and 1.34% (95%CI 0.80%-2.27%), respectively. The risk of thromboembolism of CHA2DS2-VASc score 2 group (HR=3.53, 95%CI 1.48-8.44; P=0.005), especially female patients aged 65-74 years in CHA2DS2-VASc score 2 group (HR=2.67, 95%CI 1.63-4.38; P<0.000) was significantly higher than that in patients of CHA2DS2-VASc score 0 group. Conclusion: Low-Risk Atrial Fibrillation patients with CHA2DS2-VASc score 2, especially female patients aged 65-74 years old with CHA2DS2-VASc score 2 are at higher risk of thromboembolism in low-risk AF patients. For such patients, intensified oral anticoagulant therapy might be helpful to reduce the risk of thrombolism.

RESUMO

Objective: We aimed to explore the impact of digoxin use on outcomes in Chinese patients with atrial fibrillation (AF). Methods: We used the dataset from the Chinese Atrial Fibrillation Registry, a prospective, multicenter, hospital-based registry study. According to the inclusion and exclusion criteria, 10 472 eligible patients enrolled from August 2011 to December 2016 were included in this ancillary study. The patients were classified into three groups according to the status of digoxin use at study enrollment, patients already receiving digoxin before registry were represented as continuous group, patients initiated on digoxin for the first time were represented as newly group, and patients without digoxin prescription at enrollment were represented as control group. Patients were followed by telephone or outpatient service every 6 months. Kaplan-Meier survival analysis and Cox proportional hazards regression models were used to investigate the association of digoxin use with adverse outcomes (all-cause death, cardiovascular death and cardiovascular hospitalization). Results: In the overall study population, men accounted for 42.8%, and the average age was (66.9±11.8) years. There were 777(7.42%)patients in continuous group, 375 (3.58%) patients in newly group, and 9 320 (89.00%) patients in control group. Compared with the control group, the patients in the newly group and the continuous group were older, had faster heart rate, lower estimated glomerular filtration rate, higher proportion of persistent atrial fibrillation, heart failure, renal insufficiency, diabetes mellitus, ischemic stroke, coronary heart disease, vascular disease and bleeding history. At the same time, the patients in the newly group and the continuous group were treated more often with anticoagulants, antiplatelet drugs, ACE inhibitors or angiotensin receptor blockers, beta-receptor blockers while the proportion of antiarrhythmic drugs was lower as compared to control group (P<0.05). During a median follow-up of 36 months (interquartile range: 18-48 month), risk of all-cause mortality was significantly higher in newly group compared to control group (7.3% vs. 4.7%, P<0.05), the rates of all-cause mortality, cardiovascular death and cardiovascular hospitalization were all higher in continuous group than in control group (8.0% vs. 4.7%; 4.7% vs. 3.0%; 16.7% vs. 11.8%; P all<0.05). After adjustment for age, male, body mass index, blood pressure, heart rate, renal function, AF type, history of stroke, heart failure, diabetes, coronary artery disease and other drugs treatment, the association between newly group and adverse outcomes was not significant, however, digoxin use was associated with increased all-cause mortality (HR 1.26; 95%CI 1.04-1.56; P=0.019), cardiovascular death (HR 1.38; 95%CI 1.08-1.77, P =0.01), and cardiovascular hospitalization (HR 1.10; 95%CI 1.06-1.52, P=0.02) in continuous group. Conclusion: Continuous digoxin use is associated with a significant increase in adverse outcomes among Chinese patients with atrial fibrillation.

RESUMO

Objective: To investigate the impact of history of hypertension and blood pressure levels on the thromboembolism risk in the setting of nonvalvular atrial fibrillation (NVAF). Methods: China Atrial Fibrillation Registry Study prospectively enrolled 25 512 atrial fibrillation (AF) patients between August 2011 and December 2018. After exclusion of patients with valvular AF, hypertrophic cardiomyopathy, receiving anticoagulation or ablation therapy at the enrollment, 7 757 patients were included in analysis. The primary endpoint was the time to the first occurrence of ischemic stroke or systemic embolism. Cox proportional hazards models were performed to evaluate whether a history of hypertension or blood pressure levels were independently associated with thromboembolism. Results: During a mean follow up of (35±25) months, 455 (5.9%)thromboembolic events occurred. The crude incidence rate of thromboembolism in patients with a history of hypertension was higher than that in patients without hypertension (2.38 vs. 1.35 per 100 patient-years, χ²=16.8,Log-rank P<0.001). Patients were further divided into 4 groups according to systolic blood pressure (SBP) levels at baseline, the crude incidence rate of thromboembolism significantly increased in proportion to the elevation of SBP levels (χ²=17.9,Log-rank P<0.001). However, there was no significant difference in thromboembolism risk among 4 groups stratified by diastolic blood pressure (DBP) levels (χ²=0.6,Log-rank P=0.907). Multivariable regression analysis showed that history of hypertension was independently associated with a 27% higher risk of thromboembolism (HR=1.27, 95%CI 1.01-1.61, P=0.045). Patients with SBP≥140 mmHg (1 mmHg=0.133 kPa) was associated with 36% higher risk of thromboembolism than patients with SBP<120 mmHg (HR=1.36, 95%CI 1.02-1.82, P=0.036). However, patients with SBP 120-129 mmHg or 130-139 mmHg were not at a higher risk of thromboembolism as compared to the patients with SBP<120 mmHg (SBP 120-129 mmHg: HR=1.23, 95%CI 0.90-1.67, P=0.193; SBP 130-139 mmHg: HR=1.30, 95%CI 0.95-1.77, P=0.098). In addition, DBP levels were not independently associated with the increased thromboembolism risk. Conclusion: A history of hypertension and SBP≥140 mmHg are independent predictors of thromboembolism risk in patients with NVAF. These results indicate that intensive efforts to lower SBP below 140 mmHg might be an important strategy to reduce the risk of stroke in patients with NVAF.

RESUMO

Objective: To determine the predictors of recurrent hospitalizations among atrial fibrillation (AF) patients. Methods: We analyzed data from the Chinese Atrial Fibrillation Registry (CAFR), a prospective cohort study involving non-valvular atrial fibrillation (NVAF) patients from Augest 2011 to December 2017. A total of 5 349 NVAF patients with a minimum of 48 months follow-up were included for analysis. Data including patient demographics, complications, medical and ablation history were collected. The maximum number of all-cause hospitalizations within one-year for each patient served as the primary endpoint. Patients hospitalized less than twice within one-year were defined as non-recurrent hospitalizations group, those hospitalized at least twice within one-year were definned as recurrent hospitalizations group. Logistic regression model was used to identify associated risk factors for recurrent hospitalizations. Results: Of 5 349 NVAF patients, those hospitalized for 0, 1, 2, 3, 4 and at least 5 times within one-year was 2 703 (50.5%), 1 776 (33.2%), 642 (12.0%), 161(3.0), 52 (1.0%), 15 (0.3%), respectively. Eight hundred and seventy (16.3%) patients were included in recurrent hospitalizations group, 4 479 (83.7%) patients were included in non-recurrent hospitalizations group. Compare with non-recurrent hospitalizations group, patients in recurrent hospitalizations group was more likely to be older and female, more frequently had a history of hypertension, heart failure, coronary heart disesase, ischaemic stroke/transient ischaemic attack, diabetes mellitus, peptic ulcer, a AF duration for more than 1 year, medication including drugs for ventricular rate control, statin, angiotensin-converting enzyme inhibitors (ACEI)/angiotensin receptor blocker (ARB) and higher CHA(2)DS(2)-VASc scores (P<0.05), but less frequently had higher education, a history of drinking, smoking and ablation (P<0.05). Multivariable analysis showed that age 50-64 (OR=1.47, 95%CI 1.20-1.80), age≥65 (OR=1.89, 95%CI 1.50-2.38), female (OR=1.21, 95%CI 1.01-1.46), hypertension history (OR=1.42, 95%CI 1.16-1.74), heart failure history (OR=1.73, 95%CI 1.37-2.18), coronary heart disease history (OR=1.63, 95%CI 1.31-2.03), peptic ulcer history (OR=2.00, 95%CI 1.18-3.39) were independent risk factors for recurrent hospitalizations, while higher education (college or above) (OR=0.82, 95%CI 0.69-0.99) was the protective factor for recurrent hospitalizations. Conclusions: Nearly 1 in 6 of AF patients were admitted to hospital more than once within one year in this NVAF cohort. Age≥50, female, hypertension history, heart failure history, coronary heart disease history, peptic ulcer history are associated with an increased risk of recurrent hospitalizations.

RESUMO

<p><b>BACKGROUND</b>Warfarin is the most common oral anticoagulant to decrease the stroke risk associated with atrial fibrillation (AF). There are very few prospective studies that have explored whether warfarin has an association with damage on renal function in Chinese patients with nonvalvular AF (NVAF). The aim of this study was to evaluate the effects of warfarin on renal function and study the factors associated with kidney dysfunction in Chinese adult NVAF patients without dialysis therapy.</p><p><b>METHODS</b>From January 2011 to December 2013, a total of 951 NVAF patients from 18 hospitals were enrolled. The estimated glomerular filtration rate (eGFR) was calculated from baseline and follow-up serum creatinine levels. Kaplan-Meier survival curves compared the survival of a ≥25% decline in eGFR (hereafter, endpoint), while Cox models estimated hazard ratios (HR s) and 95% confidence intervals for this event after adjustment for age, gender, and selected potential risk factors for renal dysfunction. Cox regression analysis of the various clinical potential variables was performed to identify the predictors of a ≥25% decline in eGFR.</p><p><b>RESULTS</b>After a 58-month follow-up, 951 NVAF patients were divided by observation into warfarin (n = 655) and no anticoagulation groups (n = 296) and 120 (12.6%) patients experienced renal endpoint. Kaplan-Meier survival curves showed that the survival period was not different in the two groups (χ2 = 0.178, log-rank P= 0.67), but patients with systolic blood pressure (SBP) <140 mmHg have significant difference with patients with SBP ≥140 mmHg (χ2 = 4.903, log-rank P= 0.03). Multivariate Cox regression analysis revealed baseline eGFR and SBP as independent predictors of the endpoint, with HR s of 1.00, and 1.02, respectively.</p><p><b>CONCLUSION</b>In patients with NVAF, eGFR and SBP are associated with the deterioration of kidney function while Warfarin is not the risk factor of the ≥25% decline in eGFR.</p><p><b>TRIAL REGISTRATION</b>Chinese Clinical Trial Registry (No. ChiCTR-OCH-13003729); http://www.chictr.org.cn/showproj.aspx?proj = 5831.</p>

RESUMO

BACKGROUND: The genus Liposcelis (Psocoptera: Troctomorpha) has more than 120 species with a worldwide distribution and they pose a risk for global food security. The organization of mitochondrial (mt) genomes varies between the two species of booklice investigated in the genus Liposcelis. Liposcelis decolor has its mt genes on a single chromosome, like most other insects; L. bostrychophila, however, has a multipartite mt genome with genes on two chromosomes. RESULTS: To understand how multipartite mt genome organization evolved in the genus Liposcelis, we sequenced the mt genomes of L. entomophila and L. paeta in this study. We found that these two species of booklice also have multipartite mt genomes, like L. bostrychophila, with the mt genes we identified on two chromosomes. Numerous pseudo mt genes and non-coding regions were found in the mt genomes of these two booklice, and account for 30% and 10% respectively of the entire length we sequenced. In L. bostrychophila, the mt genes are distributed approximately equally between the two chromosomes. In L. entomophila and L. paeta, however, one mt chromosome has most of the genes we identified whereas the other chromosome has largely pseudogenes and non-coding regions. L. entomophila and L. paeta differ substantially from each other and from L. bostrychophila in gene content and gene arrangement in their mt chromosomes. CONCLUSIONS: Our results indicate unusually fast evolution in mt genome organization in the booklice of the genus Liposcelis, and reveal different patterns of mt genome fragmentation among L. bostrychophila, L. entomophila and L. paeta.

RESUMO

The transcriptome database of the oriental fruit fly, Bactrocera dorsalis (Hendel), was used to identify the functional gene-microsatellite (EST-SSR) markers and to analyze the SSR loci information. In total, 1890 EST-SSR loci were identified, of which, 1296 SSR sequences could be used for primer design. The average distribution frequency of the transcriptomic SSRs was 1/10. 21 kb. However, these distribution frequencies varied considerably among different types of repeat SSRs. The tri-nucleotide repeat SSRs were found to have the highest frequency among the different types of repeat SSRs in the EST-SSR of B. dorsalis. Combining with other literatures, we inferred that the tri-nucleotide repeat SSRs were the most abundant EST-SSR in all of insects. In this study, 42 pairs of EST-SSR primers were designed and 18 pairs produced amplification bands of expected sizes. According to the results of other related literatures, the practices and challenges of strategy for SSR isolation from insect transcriptome databases were discussed, and the problems which should be considered in the screening of insect transcriptomic EST-SSR were put forward.

RESUMO

OBJECTIVE: To evaluate the effect of cesarean section (CS) and vaginal delivery (VD) on postpartum stress urinary incontinence (SUI) and pelvic floor muscles strength and to find out the correlated obstetric factors and prevention for postpartum SUI. METHODS: Totally, 788 women, who visited the antenatal clinics, delivered and had the follow-up at 6-8 weeks after delivery in Beijing Obstetrics and Gynecology Hospital in the year of 2008, were enrolled in this study and were divided into 3 groups: CS group (n = 212); normal vaginal delivery (NVD) group (n = 534) and forceps delivery (FD) group (n = 42). Women in the NVD and FD group were merged into one VD group and then divided into SUI and non-SUI group. Information of delivery mode and the correlated obstetric factors were obtained through questionnaires and medical records. Femiscan pelvic floor muscle examine system was applied to measure the pelvic floor muscle strength to understand the relationship between postpartum SUI and pelvic floor muscle strength. RESULTS: (1) Incidence of SUI: the overall proportion of women who complained of urinary incontinence (UI) during pregnancy was 15.4% (121/788), and it was 15.9% (85/534), 11.9% (5/42) and 14.6% (31/212) in the NVD, FD and CS group, respectively (P > 0.05). The overall incidence of postpartum SUI was 17.1% (135/788), and it was 19.1% (102/534), 26.2% (11/42) and 10.4% (22/212) in the NVD, FD and CS group, respectively, with significant difference between the NVD and FD group, and between the CS and NVD group (all P < 0.01). (2) The associated obstetric factors of postpartum SUI: among the VD group, 113 women were in the postpartum SUI group and 463 in the non-SUI group. Univariate analysis and logistic multivariate analysis showed that delivery mode, neonatal birth weight and UI during pregnancy were risk factors of postpartum SUI. CS decreased and higher neonatal birth weight and UI during pregnancy increased the risk of postpartum SUI. In the VD group, neonatal birth weight, forceps delivery and UI during pregnancy increased the incidence of postpartum SUI (P < 0.01), but no correlation was found with labor analgesia, duration of labor, episiotomy, breast feeding, volume of postpartum bleeding, gestational weeks at delivery, induction and pre-pregnant BMI, etc (all P > 0.05). (3) Pelvic floor electromyogram: pelvic floor muscles strength in the CS group was significantly higher than that of the VD group [activity value: (19.7 +/- 9.9) microv vs (14.8 +/- 8.4) microv; work value: (84.5 +/- 37.2) microv vs (78.8 +/- 28.2) microv; peak value: (25.5 +/- 12.5) microv vs (19.7 +/- 11.8) microv, all P < 0.01]. Among women in the VD group, the relaxation value and the ratio of relaxation value over activity value (r/a) in the postpartum SUI group were significantly lower than those in the non-SUI group [relaxation value: (1.7 +/- 1.8) microv vs (3.0 +/- 3.9) microv; r/a ratio: 0.2 +/- 0.2 vs 0.3 +/- 0.5, all P < 0.01]. The r/a ratio in the VD group showed no difference compared to that in the CS group (0.2 +/- 3.5 vs 0.2 +/- 0.2, P > 0.05). CONCLUSION: Women experienced vaginal delivery, either NVD or FD, have a higher incidence of postpartum SUI than those delivered through CS. UI during pregnancy, forceps delivery and neonatal birth weight are risk factors of postpartum SUI.

RESUMO

The expression of peroxisome proliferator-activated receptor gamma (PPARgamma) was investigated in the hypothalamic-pituitary-adrenal (HPA) axis of weaned pigs after injection with 100 microg/kg bodyweight Escherichia coli lipopolysaccharide (LPS) (n=6) and control pigs injected with sterile saline (n=6). LPS increased PPARgamma mRNA and protein expression in the hypothalamus (23.8 and 3.1-fold relative to controls, respectively), pituitary gland (9.2 and 2.0-fold, respectively) and adrenal gland (3.5 and 2.3-fold, respectively) (P<0.05). LPS also induced an increase in PPARgamma immunohistochemical staining in the hypothalamus (1.3-fold), adenohypophysis (1.3-fold), adrenal cortex (1.4-fold) and adrenal medulla (1.6-fold) (P<0.05). Concurrent with up-regulated expression of PPARgamma, LPS increased the concentrations of plasma corticotrophin-releasing hormone (2.1-fold) and adrenocorticotrophin (1.4-fold) (P<0.05). LPS also induced elevations of interleukin 6 and tumour necrosis factor alpha mRNA levels in the hypothalamus (4.0 and 3.2-fold, respectively), pituitary gland (20.7 and 5.1-fold, respectively) and adrenal gland (3.9 and 3.3-fold, respectively) (P<0.05). PPARgamma may play a role in the regulation of neuroendocrine responses associated with immunological stress in pigs.

RESUMO

OBJECTIVE: To explore the endocrinal factors which influence the aggressive behavior of adolescents. METHODS: The levels of cortisol (CORT), testosterone (T), prolactin (PRL), and growth hormone (GH) in saliva from 20 aggressive students and 20 non-aggressive control students were measured by radioimmunoassay (RIA). The students were matched for their gender, age, grade, stage of pubertal development, and economic status of their families. RESULTS: The salivary T levels were 22.20 +/- 14.50 pg/mL and 19.54 +/- 12.52 pg/mL in aggressive male and female students, 13.20 +/- 6.85 pg/mL and 5.24 +/- 3.03 pg/mL in non-aggressive male and female students (P < 0.05). The male aggressive students had a lower level of CORT in saliva than non-aggressive male students (P < 0.05). There were no significant differences in the salivary levels of PRL or GH between the aggressive and non-aggressive groups. Correlation analysis revealed a negative relationship in male students between the salivary CORT levels and the aggression factor scores of the child behavior checklist (CBCL). In addition, the data also showed a positive relationship between the salivary T levels and the aggression factor scores of CBCL in female students. Multiple linear regression analysis showed that the salivary CORT level was an independent predictive factor for aggressive behaviors in adolescent boys. The higher the CORT level, the less aggressive the boys were. CONCLUSION: CORT and T levels may play a certain role in adolescent aggressive behaviors.
