The potential therapeutic roles of dental pulp stem cells in spinal cord injury.

Spinal cord injury (SCI) can lead to serious functional disorders, which have serious impacts on patients and society. The current traditional treatments of SCI are not effective the injured spinal cord is difficult to repair and regenerate. In recent years, stem cell transplantation for the treatment of SCI has been a hot research topic. Dental pulp stem cells have strong abilities of self-renewal and multi-directional differentiation, and have been applied for tissue engineering and regenerative medicine. And dental pulp stem cells have certain advantages in neuro-regenetation, bringing new hope to biotherapy for SCI. This article reviews the characteristics of dental pulp stem cells and their research progress in the treatment of SCI.

Household use of solid fuel and sarcopenia among middle-aged and older adults: The China Health and Retirement Longitudinal Study.

OBJECTIVE: Few studies have examined the effects of air pollution on the risk of sarcopenia, especially pollution in indoor settings. We explored the cross-sectional and longitudinal associations of household use of solid fuel for cooking and heating, separately and simultaneously, with risk of sarcopenia. METHODS: Cross-sectional and follow-up data from the China Health and Retirement Longitudinal Study were used. Multivariable-adjusted generalized linear models and Cox proportional hazards regression models were performed to estimate the odds ratio and hazard ratio for sarcopenia, respectively. RESULTS: 11,494 (median age: 57.0 years; 47.4 % males) and 7483 (median age: 57.0 years; 46.9 % males) participants were included in the cross-sectional and longitudinal study, respectively. After fully adjusting for covariates, including outdoor concentration of particulate matter (PM2.5), both the use of solid fuels for cooking and use for heating were positively associated with incident sarcopenia in the longitudinal analyses, with hazard ratios (95 % confidence interval) of 1.56 (1.28-1.89) and 1.26 (1.04-1.52), respectively. Moreover, significant multiplicative and/or additive interactions were observed between age, smoking and cooking with solid fuel and risk of sarcopenia (all P for interaction <0.05). Similar results were found in the cross-sectional analyses. CONCLUSIONS: Household use of solid fuel was significantly associated with a higher risk of sarcopenia, while ageing and smoking had synergetic effects with burning solid fuels on the risk of sarcopenia. Our results highlight the importance of taking multi-pronged measures with respect to both air pollution and healthy lifestyle to prevent sarcopenia and promote healthy ageing.

Reprogramming of DNA methylation patterns mediates perfluorooctane sulfonate-induced fetal cardiac dysplasia.

Prenatal exposure to perfluorooctane sulfonate (PFOS) is associated with adverse health effects, including congenital heart disease, yet the underlying mechanisms remain elusive. Herein, we aimed to evaluate the embryotoxicity of PFOS using C57BL/6 J mice to characterize fetal heart defects after PFOS exposure, with the induction of human embryonic stem cells (hESC) into cardiomyocytes (CMs) as a model of early-stage heart development. We also performed DNA methylation analysis to clarify potential underlying mechanisms and identify targets of PFOS. Our results revealed that PFOS caused septal defects and excessive ventricular trabeculation cardiomyopathy at 5 mg/kg/day in embryonic mice and inhibited the proliferation and pluripotency of ESCs at concentrations >20 µM. Moreover, it decreased the beating rate and the population of CMs during cardiac differentiation. Decreases were observed in the abundances of NPPA+ trabecular and HEY2+ compact CMs. Additionally, DNA methyl transferases and ten-eleven translocation (TET) dioxygenases were regulated dynamically by PFOS, with TETs inhibitor treatment inducing significant decreases similar as PFOS. 850 K DNA methylation analysis combined with expression analysis revealed several potential targets of PFOS, including SORBS2, FHOD1, SLIT2, SLIT3, ADCY9, and HDAC9. In conclusion, PFOS may reprogram DNA methylation, especially demethylation, to induce cardiac toxicity, causing ventricular defects in vivo and abnormal cardiac differentiation in vitro.

Life's Essential 8 and risk of incident heart failure in community population without cardiovascular disease: Results of the sub-cohort of China PEACE Million Persons Project.

OBJECTIVE: The American Heart Association has introduced the Life's Essential 8 metrics to evaluate and promote cardiovascular health (CVH) and we aimed to evaluate the association of CVH and incident heart failure (HF). METHODS: The China PEACE Million Persons Project is a population-based cardiovascular disease (CVD) screening study. This was a sub-cohort of the project that included individuals free of CVD at baseline. Components and classifications of CVH, including diet, physical activity, smoking status, sleep status, body mass index (BMI), non-high density lipoprotein (non-HDL), blood glucose and blood pressure, were determined based on the Life's Essential 8. CVH status was categorized as poor, intermediate and ideal status. HF cases were identified by linking hospital records. RESULTS: Among the cohort (n = 38,571, median age 54 years and women 60.5%), proportion of individuals with poor, intermediate and ideal CVH was 30.7%, 56.9% and 12.4%. After a median follow-up of 3.56 years, the incidence of HF in individuals with poor, intermediate and ideal CVH was 2.5%, 1.1% and 0.5% respectively. Compared to poor CVH, intermediate (adjusted HR: 0.52 [95% CI: 0.43-0.61]) and ideal CVH (adjusted HR: 0.38 [95% CI: 0.26-0.57]) were associated with a lower HF risk. A gradient of association between CVH and HF risk was observed (P-trend<0.001). Ideal physical activity, ideal smoking status, and intermediate and ideal status of BMI, blood glucose and blood pressure were associated with a lower HF risk. CONCLUSION: Poor CVH was associated with an increased risk of HF, and promotion of CVH may help prevent HF development.

System analysis based on the lysosome-related genes identifies HPS4 as a novel therapy target for liver hepatocellular carcinoma.

Background: Liver cancer is a leading cause of cancer-related deaths worldwide. Lysosomal dysfunction is implicated in cancer progression; however, prognostic prediction models based on lysosome-related genes (LRGs) are lacking in liver cancer. This study aimed to establish an LRG-based model to improve prognosis prediction and explore potential therapeutic targets in liver cancer. Methods: Expression profiles of 61 LRGs were analyzed in The Cancer Genome Atlas liver cancer cohorts. There were 14 LRGs identified, and their association with clinical outcomes was evaluated. Unsupervised clustering, Cox regression, and functional assays were performed. Results: Patients were classified into high-risk and low-risk subgroups based on the 14 LRGs. The high-risk group had significantly worse overall survival. Aberrant immune infiltration and checkpoint expression were observed in the high-risk group. Furthermore, HPS4 was identified as an independent prognostic indicator. Knockdown of HPS4 suppressed liver cancer cell proliferation and induced apoptosis. Conclusion: This study developed an LRG-based prognostic model to improve risk stratification in liver cancer. The potential value of HPS4 as a therapeutic target and biomarker was demonstrated. Regulation of HPS4 may offer novel strategies for precision treatment in liver cancer patients.

Temporal Trends in the Incidence and Mortality of Major Reproductive-Related Cancers in Women in Guangzhou From 2010 to 2020: A Joinpoint and Age-Period-Cohort Study.

Objective: To understand the temporal trends of cancer incidence and mortality in women in Guangzhou during the past 11 years and provide clues for future research. Methods: Data were obtained from the Guangzhou Cancer and Death Registry. Average annual percentage changes (AAPCs) in age-standardized incidence rates (ASIRs) and age-standardized mortality rates (ASMRs) were obtained by joinpoint regression. The age-period-cohort (APC) model was generated to quantify the effects of age, period, and cohort. Results: The ASIRs for cervical (AAPC = -4.3%) and ovarian (AAPC = -3.2%) cancers showed a downward trend during 2010-2020, and that for uterine cancer showed an upward trend. The ASMRs of breast (APC = 5.0%) and cervical (APC = 8.8%) cancers increased. The APC model highlights different age, period, and birth cohort effects depending on the cancer site. Conclusion: The ASIRs for cervical and ovarian cancers among women in Guangzhou showed a decreasing trend during the period. The APC model showed mortality for 4 cancers increased with age. Incidence and mortality decreased with increasing birth cohort. Annual reproductive cancer screening is recommended for women of appropriate age to reduce the disease burden.

Impact of extracorporeal membrane oxygenation in immunocompetent children with severe adenovirus pneumonia.

BACKGROUND: Severe adenovirus (Adv.) pneumonia can cause significant mortality in young children. There has been no worldwide consensus on the impact of extracorporeal membrane oxygenation (ECMO) in immunocompetent children with severe Adv. pneumonia. This study aimed to assess the impact of ECMO in immunocompetent children with severe Adv. pneumonia. METHODS: This study evaluated the medical records of 168 hospitalized children with severe Adv. pneumonia at the Guangzhou Women and Children's Medical Center between 2019 and 2020.Nineteen patients in the ECMO group and 149 patients in the non-ECMO group were enrolled. RESULTS: Between these two groups, there were no differences in host factors such as sex, age (all P > 0.05). Significant differences were observed in shortness of breath/increased work of breathing; cyanosis; seizures; tachycardia; the partial pressure of oxygen in arterial blood (PO2); the ratio of PaO2 to the fraction concentration of oxygen in inspired air (FiO2; P/F); white blood cell, lymphocyte, monocytes, lactate dehydrogenase (LDH), serum albumin, and procalcitonin levels; and, pulmonary consolidation (all P < 0.05). There were significant differences in the parameters of mechanical ventilation (MV) therapy and complications such as respiratory failure, acute respiratory distress syndrome, septic shock, length of hospitalization, and death (all P < 0.05). The maximum axillary temperatures, respiratory rates, heart rates and LDH levels after receiving ECMO were significantly lower than those before ECMO (all P < 0.05). Additionally, SPO2, PO2, and P/F were significantly higher than those before ECMO (all P < 0.05). In MV therapy, FiO2, PIP, and PEEP were significantly lower than those before ECMO (all P < 0.05). CONCLUSIONS: In our study, the clinical conditions of the patients in the ECMO group were much more severe than those in the non-ECMO group. Our study showed that ECMO might be beneficial for the patients with severe Adv. pneumonia.

Sex-specific risk factors of carotid atherosclerosis progression in a high-risk population of cardiovascular disease.

BACKGROUND: The progression of carotid intima-media thickness (cIMT) and plaques are associated with cardiovascular health, especially for high-risk population of cardiovascular disease (CVD). HYPOTHESIS: Risk factors for atherosclerosis may vary by sex. This study aimed to investigate the sex-specific risk factors of cIMT and plaque progression. METHODS: We selected subjects who were identified as high-risk population of CVD, and collected their carotid ultrasound data and baseline characteristics. Linear regression and logistic regression analyses were used to identify risk factors for cIMT and plaque progression. Sex-specific risk factors were identified respectively. RESULTS: A total of 7908 participants were included. The mean age was 57.75 ± 9.45 years and 61.51% were female. During mean follow-up of 1.92 ± 0.89 years, the median annual cIMT change rate was -7.25 µm/year. Seven hundred and fifteen subjects free from plaques at baseline developed plaque. Age, smoking, hypertension, and diabetes were common risk factors for carotid atherosclerosis progression in all participants. Smoking and alcohol drinking were significantly associated with increased cIMT change in women, while hypertension and antihypertensive medication were significant in men. Increased total cholesterol and diabetes were significantly associated with new plaque presence in women, while smoking, increased triglyceride, and dyslipidemia were significant in men (p ˂ .05 for all cases). The association of baseline cIMT and smoking with annual cIMT change rate and increased total cholesterol with new plaque presence were significantly differentiated between both sexes (p for interaction ˂ .05). CONCLUSIONS: The risk factors for cIMT and plaque progression differed by sex.

Association between sociodemographic status and cardiovascular risk factors burden in community populations: implication for reducing cardiovascular disease burden.

BACKGROUND: We aimed to evaluate the burden of cardiovascular (CV) risk factors in the community populations of Guangdong Province and its association with sociodemographic status (SDS). METHOD: The data were from the community populations of Guangdong Province who have participated in the China PEACE Million Persons Project between 2016 and 2020 (n = 102,358, women 60.5% and mean age 54.3 years). The prevalence of CV risk factors (smoking, drinking, overweight/obesity, hypertension, dyslipidemia and diabetes mellitus) and its association with SDS (age, sex and socioeconomic status [SES]) was evaluated cross-sectionally. RESULTS: The prevalence of overweight/obesity was 48.9%, hypertension 39.9%, dyslipidemia 18.6%, smoking 17.2%, diabetes mellitus 16.1% and drinking 5.3%. Even in young adults (aged 35-44), nearly 60% had at least 1 CV risk factor. Overweight/obesity often coexisted with other risk factors, including smoking, hypertension, dyslipidemia and diabetes mellitus. The proportion of people with no risk factor decreased with increasing age. Women were more likely than men to have no CV risk factor (29.4% vs. 12.7%). People with ≥ high school degree were more likely than those with < high school to have no risk factor (28.5% vs. 20.4%), and farmers were less likely than non-farmers to have no risk factor (20.8% vs. 23.1%). CONCLUSION: The burden of CV risk factors is high and varied by SDS in the community populations of Guangdong Province. Cost-effective and targeted interventions are needed to reduce the burden of CV risk factors at the population level.

Population Attributable Risks of Potential Modifiable Factors for Atrial Fibrillation in China: A National Survey.

Background: There is an association between atrial fibrillation (AF) and overall mortality as well as mobility. It is not known, however, what the preventable burden of AF in China is. This study aims to identify what proportion of the burden of AF may be avoided by modifiable risk factors. Methods: As part of the China National Stroke Screening and Prevention Project, 726,451 adults aged ≥40 years were enrolled in a representative cross-sectional study. The following seven factors have been categorized as modifiable risk factors for AF: body mass index, smoking, alcohol consumption, physical inactivity, hypertension, diabetes mellitus, and dyslipidemia. In order to calculate population-attributable risks (PARs), odds ratios (ORs) were calculated for selected risk factors. Results: The crude ORs increased with age (ORs ranged from 1.92 to 4.02). A total of 18,736 cases of prevalent AF have been identified. The overall prevalence of AF was 2.6%. The crude ORs increased with age (ORs range 1.92-4.03). The adjusted ORs and the corresponding confidence intervals (CIs) for these seven modifiable factors were 1.16 (95% confidence interval [CI]: 1.12-1.19), 1.56 (95% CI: 1.49-1.62), 2.15 (95% CI: 2.02-2.28), 2.07 (95% CI: 2.01-2.14), 2.71 (95% CI: 2.62-2.79), 2.10 (95% CI: 2.02-2.19), 2.52 (95% CI: 2.44-2.60), and 3.32 (95% CI: 3.18-3.48), respectively. Accordingly, 59.3% of all cases of AF could be explained by having these modifiable risk factors, among which hypertension accounted for the greatest share. Conclusion: In China, hypertension is the leading preventable cause of AF, and more than half of these cases can be prevented through improving those modifiable risk factors.

Development and Validation of a Model to Predict the Contract Service of Family Doctor: A National Survey in China.

Background: Previous studies have reported a relatively low utilization of family doctor contract services (FDCS) in China, while the associated factors are unknown. The current study aimed to explore the factors associated with the utilization of FDCS, and then developed and validated a predictive model based on these identified factors. Methods: We conducted a nationwide cross-sectional study using an online questionnaire, from March 2019 to April of 2019. Routinely collected variables in daily practice by family doctors were used to develop a derivation model to determine the factors associated with FDCS utilization, and then the external performance of the model was tested. Results: A total of 115,717 and 49,593 participants were included in the development and validation datasets, respectively. Nearly 6.8% of the participants who signed a contract with FDCS received healthcare services from family doctors in China. Factors associated with the utilization of FDCS included age, male sex, self-reported household income, education attainment, insurance status, self-reported health status, smoking, drinking, self-reported physical activity status, chronic disease, walking distance from the nearest community center, and illness in the last 2 weeks, with an area under the receiver operating characteristic curve (AUC) of 0.660 [95% confidence interval (CI), 0.653-0.667] and good calibration. Application of this nomogram in the validation dataset also showed acceptable diagnostic value with an AUC of 0.659 (95% CI, 0.649-0.669) and good calibration. Conclusion: Twelve easily obtainable factors in daily practice of family doctors were used to develop a model to predict the utilization of FDCS, with a moderate performance.

Layer-by-Layer Assembly of a Polysaccharide "Armor" on the Cell Surface Enabling the Prophylaxis of Virus Infection.

Airborne pathogens, such as the world-spreading severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), cause global epidemics via transmission through the respiratory pathway. It is of great urgency to develop adequate interventions that can protect individuals against future pandemics. This study presents a nasal spray that forms a polysaccharide "armor" on the cell surface through the layer-by-layer self-assembly (LBL) method to minimize the risk of virus infection. The nasal spray has two separate components: chitosan and alginate. Harnessing the electrostatic interaction, inhaling the two polysaccharides alternatively enables the assembly of a barrier that reduces virus uptake into the cells. The results showed that this approach has no obvious cellular injury and endows cells with the ability to resist the infection of adenovirus and SARS-CoV-2 pseudovirus. Such a method can be a potential preventive strategy for protecting the respiratory tract against multiple viruses, especially the upcoming SARS-CoV-2 variants.

Cost-Effectiveness analysis of combining plasma Epstein-Barr virus DNA testing and different surveillance imaging modalities for nasopharyngeal carcinoma patients in first remission.

BACKGROUND: To evaluate the cost-effectiveness of stage-based post-radiotherapy (PRT) nasopharyngeal carcinoma (NPC) surveillance strategies. METHODS: Four post-radiotherapy surveillance strategies were established by a Markov model based on data from 1664 patients: 1) clinical follow-up (CFP) with biannual Epstein-Barr virus (EBV) DNA (EBV DNA strategy); 2) CFP with biannual EBV DNA, annual head and neck magnetic resonance imaging (HNMRI), chest X-ray, abdominal ultrasonography, bone scan (only for the first two years) for five years (MCWU strategy); 3) CFP with biannual EBV DNA, annual HNMRI, chest, abdomen, pelvic computerized tomography (CT) and bone scan for the first two years, followed by annual MCWU strategy (without bone scans) for the last three years (CT strategy); 4) CFP with biannual EBV DNA, annual whole-body positron emission/computerized tomography (PET/CT) for the first two years and biannual EBV DNA for the last three years (PET/CT strategy). RESULTS: Compared with the EBV DNA strategy, the MCWU, CT, and PET/CT strategies gained 0.017, 0.047, and 0.082 quality-adjusted life years (QALY) for stage I-II patients. For stage III and IVa patients, the PET/CT strategy had a favorable incremental effectiveness (ICERs) of 0.277 and 0.385 QALY, respectively. The ICERs for the MCWU, CT, and PET/CT strategies were $74,037, $34,882, and $34,696 for stage III and $62,364, $27,981, and $28,340 for stage IVa, respectively. CONCLUSION: EBV DNA strategy was cost-effective for the long-term surveillance of stage I-II NPC patients with CR. PET/CT strategy was recommeded for patients having IVa NPC. As for stage III NPC, PET/CT strategy was still acceptable with the development of economy in China.

Maternal smoking status during pregnancy and low birth weight in offspring: systematic review and meta-analysis of 55 cohort studies published from 1986 to 2020.

BACKGROUND: Maternal smoking during pregnancy may be associated with low birth weight (LBW) in offspring and global risk estimates have not been summarized previously. We aimed to systematically explore evidence regarding maternal smoking and the LBW risk in offspring globally and examine possible causes of heterogeneity across relevant studies. METHODS: Comprehensive search of PubMed, Ovid Embase, Ovid Medline (R), and Web of science from inception until October 2021 was carried out. A random-effects meta-analysis was used to estimate the pooled odds ratio (OR) and corresponding 95% confidence interval (CI). Restricted cubic spline analysis with three knots was used to further examine the dose-response relationship. RESULTS: Literature searches yielded 4940 articles, of which 53 met inclusion criteria (comprising 55 independent studies). Maternal smoking during pregnancy was significantly associated with the risk of LBW in offspring (OR = 1.89, 95% CI = 1.80-1.98). Furthermore, an obvious dose-response relationship between the amount of cigarettes daily smoked in pregnancy and the risk of LBW in offspring was observed. The results of subgroup analyses indicated that the risk of maternal smoking on LBW was larger in more recently conducted studies (P = 0.020) and longer period of active smoking during pregnancy (P = 0.002). No evidence of publication bias was found. CONCLUSIONS: In summary, maternal smoking in pregnancy was significantly associated with a higher risk of LBW in offspring on a global scale. The risk of maternal smoking on infant LBW seems to be increasing over time, and was higher with longer smoking duration throughout pregnancy and more cigarettes smoked daily.

Polyphenols extracted from Shanxi-aged vinegar exert hypolipidemic effects on OA-induced HepG2 cells via the PPARα-LXRα-ABCA1 pathway.

Hyperlipidemia is one of the key risk factors causing many chronic diseases, and lowering blood lipid levels can prevent many diseases. In this paper, a hyperlipidemic cell model of oleic acid (OA) induced hepatocellular carcinoma cells (HepG2) was established using polyphenols extracted from Shanxi-aged vinegar (SAVEP). The effects of SAVEP on nuclear damage, mitochondrial membrane potential, apoptosis, cellular lipid deposition, and lipid metabolism protein expression in HepG2 hyperlipidemic cells were examined to investigate the lipid-lowering mechanism of SAVEP at the cellular level. The results showed that SAVEP could reduce the content of TC/TG index, repair the nuclear damage, reduce lipid accumulation and finally decrease the rate of apoptosis by up-regulating the expression of key proteins such as PPARα, LXRα, and ABCA1 in the process of lipid metabolism. PRACTICAL APPLICATIONS: In this thesis, the hypolipidemic activity of polyphenol extracts from Shanxi-aged vinegar was analyzed on the level of HepG2 cells. The hypolipidemic mechanism of oxidative stress, lipid metabolism and inflammatory stress was also elucidated. It provided a theoretical basis for the in-depth understanding of the hypolipidemic health effects of Shanxi-aged vinegar.

Safe Limits of Contrast Media for Contrast-Induced Nephropathy: A Multicenter Prospective Cohort Study.

Background: The safe level of contrast media volume (CV) is an important modifiable risk factor for contrast-induced nephropathy (CIN). The safe limit of CV remains unclear and is limited to single-center studies. Our objective was to determine the association between the ratio of contrast volume-to-glomerular filtration (CV/GFR) and CIN in patients undergoing coronary angiography (CAG) or percutaneous coronary intervention (PCI). Methods: We assessed the association between CV/GFR and the risk of CIN in 4,254 patients undergoing CAG or PCI from the year 2013 to 2016 and enrolled in the REICIN (REduction of rIsk for Contrast-Induced Nephropathy), a prospective, multicenter, observational cohort study. CV/GFR was calculated at the five primary GFR equation. Results: Sixty-nine (1.7%) patients with a median contrast volume-to-chronic kidney disease epidemiology collaboration (CV/CKD-EPI) ratio of 2.16 (1.30-3.93) have suffered from CIN. The CV/CKD-EPI demonstrated the best performance of model fit, discrimination (area under curve = 0.736), calibration, reclassification, and equation conciseness (1 variable). The CV/CKD-EPI ≥1.78 was the statistical significance associated with CIN [adjusted odds ratio, 4.64 (2.84-7.56); p < 0.001]. Furthermore, similar results were found in the subgroup analyses. Conclusions: The CV/CKD-EPI showed the best performance in patients undergoing CAG or PCI. CV/CKD-EPI ≥1.78 could be a more reliable and convenient predictor of CIN. Intraprocedural preventive measures should include a priori calculation of CV/GFR to limit contrast volume.

Comparison of Drug-Eluting Stent and Plain Old Balloon Angioplasty After Rotational Atherectomy in Severe Calcified and Large Coronary.

Drug-eluting stent (DES) is well known to be effective in severely calcified lesion after rotational atherectomy (ROTA). However, there are still some situations when stents should be avoided and plain old balloon angioplasty (POBA) should be the preferred option. The present study aims to explore whether POBA is comparably effective to DES in large and calcified coronary pretreated by ROTA in clinical outcomes.Consecutive patients treated for severely calcified lesions in the large (≥ 3 mm) coronary using ROTA + DES or ROTA + POBA were retrospectively analyzed. The major adverse cardiac events (MACE), including all-cause/cardiac death and target lesion revascularization (TLR) at 1 year and 2 years posttreatment, were compared between groups using the Cox regression analysis to identify independent predictors of TLR and MACE.The analysis included 285 cases in the ROTA + DES group and 47 cases in the ROTA + POBA group, without relevant differences in clinical baseline characteristics. Of note, lesion length was greater in the ROTA + DES group (37.2 versus 19.3 mm, P < 0.001); the ROTA + DES group had a higher rate of chronic total occlusion (CTO) lesions, with 8.4%, and the ROTA + POBA group had none. The inhospital/30-day mortality rate (5.3%, ROTA + DES; 6.4%, ROTA + POBA) and the 12- and 24-month all-cause/cardiac mortality rate (9.3%, ROTA + DES; 7.7%, ROTA + POBA) were not significantly different between the two groups. TLR rates were not significantly different between the two groups at 12 (4.6%, ROTA + DES; 4.3%, ROTA + POBA) and 24 (5.3%, ROTA + DES; 6.4%, ROTA + POBA) months.Outcomes were comparable for ROTA + DES and ROTA + POBA in severely calcified large coronary artery intervention with respect to midterm death or TLR rate, especially for short lesion of < 20 mm.

Evaluation of interactive effects between paternal alcohol consumption and paternal socioeconomic status and environmental exposures on congenital heart defects.

BACKGROUND: While the maternal risk factors on congenital heart defects (CHDs) have often been assessed, paternal contribution to CHDs, especially the joint effects of paternal risk factors on CHDs remain unknown. This study examined the major impacts of paternal alcohol consumption and its interaction (on multiplicative and additive scales) with paternal socioeconomic status (SES) and environmental exposures on CHDs in China. METHODS: A population-based case-control study involving 4,726 singleton CHDs cases and 4,726 controls (without any malformation and matched on hospital, gender, and gestational age) was conducted in Guangdong, China, 2004-2014. Information on parental demographics, behavioral patterns, disease/medication, and environmental exposures (3 months before pregnancy) was collected through face-to-face interviews. Conditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) while controlling for all parental factors. RESULTS: Paternal alcohol consumption was associated with an increased OR of CHDs (adjusted OR = 2.87, 95% CI: 2.25-3.65). Additionally, paternal smoking, industry occupation, organic solvent contact, virus infection and antibiotic use, living in rural areas, low household income, and migrant status were significantly associated with CHDs (ORs ranged: 1.42-4.44). Significant additive or multiplicative interactions were observed between paternal alcohol consumption and paternal smoking, industrial occupation, and low income on any CHDs (interaction contrast ratio [ICR] = 4.72, 95% CI: 0.96-8.47] and septal defects (ICRs ranged from 2.04 to 2.79, p < .05). CONCLUSIONS: Paternal alcohol consumption and multiple paternal factors were significantly associated with CHDs in China. Paternal smoking and low SES factors modified paternal alcohol consumption-CHDs relationships. Further studies are needed to confirm these findings.

Value of pulmonary annulus area index in predicting transannular patch placement in tetralogy of Fallot repair.

BACKGROUND: Precisely evaluating the need for transannular patch (TAP) placement is very important in the surgical treatment of tetralogy of Fallot. We hypothesized that the pulmonary annulus area index (PAAI, the pulmonary-to-aortic valve annulus cross-sectional area ratio) could be a useful and accessible predictor for TAP placement. METHODS: The medical records of patients who underwent tetralogy of Fallot repair between 1 January 2016 and 31 December 2017 were reviewed retrospectively. A total of 255 patients were included and categorized into two groups: patients who needed TAP placement and patients who did not. Various candidate predictors for TAP placement (PAAI, pulmonary annulus z-score, and velocity across the pulmonary annulus) were compared using receiver operating characteristic curves. The optimal cutoff for each predictor was assessed. RESULTS: Among the 255 patients included, 156 needed TAP placement (156/237, 65.8%). Both the PAAI (0.28 [0.20/0.34] vs 0.14 [0.09/0.19]; P < .0001) and z-score (-1.5 [-2.9, -0.4] vs -3.6 [-5.3/-2.6]; P < .0001) were smaller in the TAP group. The PAAI is a useful predictor of the pulmonary annulus z-score (AUC 0.830 vs 0.811, P = .19). Combination analysis of the PAAI and velocity across the pulmonary annulus (PV vmax ) showed better predictive value than the PAAI and z-score (AUC 0.860, sensitivity 89.7%, specificity 61.7%, P < .0001). CONCLUSIONS: Our results suggest that the PAAI is a useful and accessible predictor for TAP placement and can be applied readily and simply in clinical practice. A combination with the velocity across the pulmonary annulus could promote the accuracy of prediction.

Diabetes Mellitus Is Not a Risk Factor for Patients Supported With Left Ventricular Assist Device.

BACKGROUND: Diabetes mellitus has been proved to be a potent, independent risk factor for mortality in patients with heart failure. However, the influence of diabetes on outcomes after continuous-flow left ventricular assist device (CF-LVAD) implantation is still under debate. This study sought to investigate the effect of preoperative diabetes on all-cause mortality and major postoperative complications among patients with contemporary CF-LVAD support. METHODS: A systematic literature search (PubMed, Embase, and ISI Web of Knowledge, and Cochrane Central Register of Controlled Trials) was performed. The primary endpoint was hazard ratio for all-cause mortality. Secondary endpoints were postoperative complications, including infection, transient ischemia attack, intracranial hemorrhage, and pump thrombosis. A meta-analysis was conducted to generate pooled hazard ratio and 95% confidence interval (CI) for all-cause mortality and pooled odds ratio (OR) and 95% CI for postoperative complications. RESULTS: A total of 1120 patients (478 diabetic patients, 642 nondiabetic patients) from four studies were included in this study. Diabetes did not increase the risk for all-cause mortality among patients with CF-LVAD support (hazard ratio 1.33; 95% CI, 0.88 to 2.02; P = .18). Moreover, pooled analysis demonstrated no significant difference was found in the diabetes and nondiabetes groups in terms of infection (OR 1.18; 95% CI, 0.89 to 1.56; P = .24), transient ischemia attack (OR 1.30; 95% CI, 0.86 to 1.97; P = .21), intracranial hemorrhage (OR 1.86; 95% CI, 0.93 to 3.71; P = .08), and pump thrombosis (OR 1.01; 95% CI, 0.68 to 1.48; P = .97). CONCLUSIONS: The results of this meta-analysis demonstrate that diabetes does not increase all-cause mortality or rates of major adverse events during contemporary CF-LVAD support.
