Coal is one of the world’s main energy resources,accounting for approximately 68%of China’s current total power generation.However,several studies have demonstrated that dust,exhaust fumes,and other harmful factors in coal mines increase the risk of cardiovascular disease(CVD)among miners^([1]).Arterial stiffness(AS)is an independent risk factor of CVD,and epidemiological studies have shown that AS plays a vital role in assessing the risk of CVD^([2]).

Relationships between nonoptimal temperatures and cardiovascular disease(CVD)mortality have been well documented.However,evidence of the association between temperature variability(TV)and CVD morbidity is limited.This study aimed to quantify the risk and burden of CVD-related hospitalization associated with the magnitude and direction of TV.Data on meteorology and population-based hospitalizations for myocardial infarction(MI)and stroke were collected in Guangzhou,China,from 2013 to 2017.Hourly temperature variability(HTV)was measured as the standard deviation of hourly temperature records over specific exposure days.The direction(upward or downward)of HTV was defined as the average daily mean temperature change relative to that of the previous day during the exposure period.Quasi-Poisson regression was applied to assess the impact of HTV after adjusting for the daily mean temperature,and the hospitalization fractions attributable to HTV were calculated.A 1℃-increase in HTV was significantly associated with a 2.24%and 1.72%increase in hospitalizations for MI and hemorrhagic stroke(HS)at lag 0–1 d,respectively,and a 1.55%increase in hospitalizations for ischemic stroke(IS)at lag 0–3 d.During the study period,5.99%,4.64%,and 4.53%of MI,HS,and IS hospitalizations,respectively,were attributable to HTV.The upward TV exerts acute effects on CVD hospital admissions,whereas the impact of downward TV generally lags.These findings highlight the importance of the magnitude and direction of temperature fluctuations,in addition to the mean level,in assessing the adverse health impacts of temperature variations.

To the Editor:Hypertension is one of the leading risk factors for cardiovascular disease and affects approximately 30%of the adult population.^([1,2])Environmental heavy metal pollution is an important public health concern.Toxic metals may increase the risk of hypertension or other cardiovascular diseases,even beyond the influence of conventional behavioral risk factors.^([3])Meanwhile certain essential trace elements,such as selenium,zinc,and iron,are involved in various enzyme reactions directly related to blood pressure regulation and are beneficial to the human body within a specific range.^([4])The analysis of health outcomes specific to metal mixtures is challenging by nonlinear relationships and interactions between toxic metals and essential trace elements.^([5])The development of innovative statistical methods for analyzing mixtures has greatly facilitated the exploration of the health effects of multiple pollutant exposures,such as Bayesian kernel machine regression(BKMR)and quantile g-computation(QG-C).

To the Editor:Tricuspid regurgitation(TR)associated with valve disease is a general medical issue with growing prevalence and socioeconomic burden.TR,especially moderate or severe TR,has been reported to be associated with an increased risk of heart failure and mortality.^([1])Studies have shown that blood calcium levels and blood phosphorus levels have a great influence on the human body,especially on the cardiovascular system.Elevated serum calcium levels were reported to be a risk factor for cardiovascular disease.^([2])A meta-analysis reported that moderate dietary calcium intake protects against cardiovascular and all-cause mortality and that calcium supplementation reduces mortality in women.^([3])

OBJECTIVES Misdiagnosis of acute aortic syndrome(AAS)significantly increases mortality.Tenascin-C(TN-C)is an extracellular matrix glycoprotein related to cardiovascular injury.The elevation of TN-C in AAS and whether it can discriminate suddenonset of acute chest pain in Chinese remains unclear.METHODS We measured the plasma concentration of TN-C by ELISA in a cohort of 376 patients with chest or back pain.Measures to discriminate AAS from acute coronary syndrome(ACS)were compared and calculated.RESULTS From October 2016 to September 2021,376 undiagnosed patients with chest or back pain were enrolled.166 of them were finally diagnosed as AAS,100 were ACS and 110 without cardiovascular diseases(NCV).TN-C was significantly elevated in AAS at 18.18 ng/mL(IQR:13.10–27.68)compared with 7.51 ng/mL(IQR:5.67–11.38)in ACS(P<0.001)and 3.68 ng/mL(IQR:2.50–5.29)in NCV(P<0.001).There was no significant difference in TN-C level among the subtypes of AAS.Of the 166 AAS patients,the peaked level of TN-C was at acute stage(P=0.012),then a slight of decrease was observed at subacute stage.The area under receiver operating characteristic curve for AAS patients versus NCV was 0.979(95%CI:0.964-0.994)for TN-C.At a cutoff level of 11.474 ng/mL,TN-C has a sensitivity of 76.0%,specificity of 85.5%,accuracy of 82.0%,positive predictive value(PPV)of 76.0%,negative predictive value(NPV)of 85.5%.Diagnostic performance of TN-C was superior to D-dimer and hs-cTnT.CONCLUSIONS The concentration of serum TN-C in AAS patients was significantly higher than that in ACS patients and NCV.TN-C could be a new biomarker to distinguish AAS patients in the early stage after symptoms onset from other pain diseases.

Patients with familial hypercholesterolemia(FH)have elevated low-density lipoprotein cholesterol(LDL-C)levels and are at high risk of premature cardiovascular disease.1 Heterozygous FH(HeFH)is one of the commonest genetic disorders,and is more frequent among those with ischemic heart disease(IHD),atherosclerotic cardiovascular disease(ASCVD)and premature IHD.

Pregnant and postnatal women are a high-risk population particularly prone to rapid progression to sepsis with significant morbidity and mortality worldwide.Moreover,severe maternal infections can have a serious detrimental impact on neonates with almost 1 million neonatal deaths annually attributed to maternal infection or sepsis.In this review we discuss the susceptibility of pregnant women and their specific physiological and immunological adaptations that contribute to their vulnerability to sepsis,the implications for the neonate,as well as the issues with antimicrobial stewardship and the challenges this poses when attempting to reach a balance between clinical care and urgent treatment.Finally,we review advancements in the development of pregnancy-specific diagnostic and therapeutic approaches and how these can be used to optimize the care of pregnant women and neonates.

BACKGROUND Dyslipidemia is frequently present in patients with diabetes.The associations of remnant cholesterol and mortality remains unclear in patients with diabetes.AIM To explore the associations of remnant cholesterol with all-cause and cardiovas-cular mortality in patients with diabetes.METHODS This prospective cohort study included 4740 patients with diabetes who par-ticipated in the National Health and Nutrition Examination Survey from 1999 through 2018.Remnant cholesterol was used as the exposure variable,and all-cause and cardiovascular mortality were considered outcome events.Outcome data were obtained from the National Death Index,and all participants were followed from the interview date until death or December 31,2019.Multivariate proportional Cox regression models were used to explore the associations between exposure and outcomes,in which remnant cholesterol was modeled as both a categorical and a continuous variable.Restricted cubic splines(RCSs)were calculated to assess the nonlinearity of associations.Subgroup(stratified by sex,age,body mass index,and duration of diabetes)and a series of sensitivity analyses were performed to evaluate the robustness of the associations.RESULTS During a median follow-up duration of 83 months,1370 all-cause deaths and 389 cardiovascular deaths were documented.Patients with remnant cholesterol levels in the third quartile had a reduced risk of all-cause mortality[hazard ratio(HR)95%confidence interval(CI):0.66(0.52-0.85)];however,when remnant cholesterol was modeled as a continuous variable,it was associated with increased risks of all-cause[HR(95%CI):1.12(1.02-1.21)per SD]and cardiovascular[HR(95%CI):1.16(1.01-1.32),per SD]mortality.The RCS demonstrated nonlinear associations of remnant cholesterol with all-cause and cardiovascular mortality.Subgroup and sensitivity analyses did not reveal significant differences from the above results.CONCLUSION In patients with diabetes,higher remnant cholesterol was associated with increased risks of all-cause and cardiovascul
