Objective To interpret the major updates in the "2026 ACC/AHA Guideline on the Management of Dyslipidemia" and provide guidance for perioperative and long-term lipid management in patients undergoing cardiovascular surgery. Methods Based on the 2026 guideline and relevant cardiovascular outcome studies, this article summarized key aspects of lipid management across the entire life span, PREVENT-ASCVD risk assessment, low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (non-HDL-C) targets, lipoprotein(a) and apolipoprotein B testing, management of hypertriglyceridemia, and the use of non-statin therapies, while analyzing their clinical implications from the perspective of cardiovascular surgery. Results The 2026 guideline expanded the focus of lipid management from simple cholesterol control to comprehensive, lifelong lipid protein risk management across the entire spectrum. It recommended the PREVENT-ASCVD model, integrated risk-enhancing factors and coronary artery calcium scores to refine risk stratification, re-established LDL-C and non-HDL-C targets, strengthened management of lipoprotein(a), apolipoprotein B, and hypertriglyceridemia, and emphasized early combination lipid-lowering therapy. These updates helped identify residual cardiovascular risks in surgical patients, promoted postoperative lipid target achievement, and supported long-term secondary prevention. Conclusion The 2026 guideline advances lipid management toward precise risk stratification, goal-directed therapy, and longitudinal intervention. Standardized lipid assessment and lipid-lowering therapy should be integrated into perioperative and long-term postoperative management in cardiovascular surgery to improve long-term patient outcomes.

OBJECTIVE: The results of limited studies on the relationship between environmental pollution and dementia have been contradictory. We analyzed the combined effects of PM _2.5 and smoking on the prevalence of dementia and cognitive impairment in an elderly community-dwelling Chinese population. METHODS: We assessed 24,117 individuals along with the annual average PM _2.5 concentrations from 2012 to 2016. Dementia was confirmed in the baseline survey at a qualified clinical facility, and newly suspected dementia was assessed in 2017, after excluding cases of suspected dementia in 2015. National census data were used to weight the sample data to reflect the entire population in China, with multiple logistic regression performed to analyze the combined effects of PM _2.5 and smoking frequency on dementia and cognitive impairment. RESULTS: Individuals exposed to the highest PM _2.5 concentration and smoked daily were at higher risk of dementia than those in the lowest PM _2.5 concentration group ( OR, 1.603; 95% CI [1.626-1.635], P < 0.0001) and in the nonsmoking group ( OR, 1.248; 95% CI [1.244-1.252]; P < 0.0001). Moderate PM _2.5 exposure and occasional smoking together increased the short-term risk of cognitive impairment. High-level PM _2.5 exposure and smoking were associated with an increased risk of dementia, so more efforts are needed to reduce this risk through environmental protection and antismoking campaigns. CONCLUSION High-level PM _2.5 exposure and smoking were associated with an increased risk of dementia. Lowering the ambient PM _2.5, and smoking cessation are recommended to promote health.

OBJECTIVE: To investigate the association of various polycyclic aromatic hydrocarbon (PAH) metabolites with diverse subtypes of cardiovascular disease (CVD) risk. METHODS: A novel predicting risk of cardiovascular disease EVENTs PREVENT equation was used to estimate the 10-year diverse subtypes of CVD risk, and their associations with PAH metabolites were analyzed using multiple logistic regression models, the weighted quantile sum (WQS) model, the quantile g-computation (qgcomp) model, and a stratified analysis of subgroups. RESULTS: For this study, six thousand seven hundred and forty-five participants were selected, and significant positive associations were observed between PAHs, naphthalene (NAP), and fluorene (FLU), and the risks of total CVD, atherosclerotic cardiovascular disease (ASCVD), and heart failure (HF). NAP and FLU were the primary contributors to the effects of PAH mixtures, and their associations with total CVD, ASCVD, and HF risk were significant in younger participants (30 ≤ age < 50 years); however, the associations of phenanthrene (PHEN) with ASCVD, HF, coronary heart disease (CHD), and stroke were dominant in aging participants (age ≥ 50 years). Notably, pyrene (PYR) was negatively associated with the risk of ASCVD, HF, CHD, and stroke. Similarly, negative associations of PYR with the four CVD subtypes were noticeable in aging participants. CONCLUSION Different PAHs metabolites had different impacts on each CVD subtype among different age groups. Notably, the protective effects of PYR on ASCVD, HF, CHD, and stroke were noticeable in aging individuals.

Ambient air pollution is increasingly being recognized as a risk factor for heart failure; however, its effects on cardiac biomarkers remain unclear. This scoping review assessed the existing evidence on the association between air pollution and cardiac biomarkers in heart failure, described the key concepts, synthesized data, and identified research gaps. Following the PRISMA-ScR guidelines, PubMed, Embase, Web of Science, and CNKI databases were searched for studies on air pollution, heart failure, and biomarkers. A total of 765 records were screened, and 81 full texts were assessed for eligibility, resulting in 15 studies. The results showed that the exposure to particulate matter was associated with elevated N-terminal pro-B-type natriuretic peptide and troponin levels. Several studies have linked particulate matter exposure to a higher cardiovascular risk and heart failure biomarkers. Inflammatory and oxidative stress markers were consistently elevated across studies, supporting the biological relevance of these associations. However, few studies have focused specifically on populations with heart failure or clinically relevant biomarkers, and the evidence for gaseous pollutants remains inconclusive. These findings highlight the need to integrate environmental risk assessment into heart failure care and inform policy efforts to reduce the pollution-related cardiovascular burden. Further research should address these gaps through improved exposure assessments and the integration of mechanistic evidence.

Objective:To explore the feasibility and safety of laparoscopic combined with colonoscopic transanal total mesorectal resection (laparoscopic combined with colonoscopic taTME) in the treatment of rectal cancer.Methods:The descriptive case series analysis method was adopted. From October 2023 to February 2024, the Department of Colorectal Surgery of Li Huili Hospital, Ningbo Medical Center, performed laparoscopic combined with colonoscopic taTME on 8 patients with rectal cancer. Among the 8 patients, there were 5 males and 3 females, aged from 56 to 74 years old, with a body mass index (BMI) of 20.3-26.7 kg/m2. All patients were pathologically diagnosed with rectal adenocarcinoma. The long diameter of the tumors was 2.0-6.5 cm, the lower edge of the tumors was 3-5 cm away from the anal verge. In terms of tumor TNM staging, there were 2 cases in stage I, 3 cases in stage II, and 3 cases in stage III. The surgical conditions, postoperative curative effects, and the occurrence of complications were observed.Results:All 8 patients successfully completed laparoscopic combined with colonscopic taTME, and there was no conversion to laparotomy. The operative time was 260 to 335 minutes, the intraoperative blood loss was 50 to 100 milliliters, and the distance from the tumor to the anal margin was 0.8 to 2.0 centimeters. All patients in the group underwent protective end ileostomy, and none of them underwent permanent enterostomy. Specimens were removed from the right lower abdomen in 7 cases and through the anus in 1 case. There was no residual cancer cells at the pathological resection margins postoperatively. All patients ambulated on the first day after the operation, and began to eat on the 2nd to 3rd day after the operation. Anastomotic leakage occurred in 1 patient after the operation, and the condition improved after conservative treatment. The length of hospital stay was 21 days. The other 7 patients were discharged from the hospital 8 to 12 days after the operation. Two patients completed the ileostomy closure surgery 3 months after the operation and recovered well. The patients were followed up until April 2024, during which there were no cases of tumor recurrence or death.Conclusion:For appropriate cases, laparoscopic combined with colonoscopic taTME is safe and feasible.
