    炎症性疾病,如牙周炎和动脉粥样硬化性冠心病(ASCHD),引发促炎介质的产生。这项研究的目的是评估使用唾液白细胞介素-1β(IL-1β)的准确性,白细胞介素-18(IL-18),和gasderminD(GSDMD)从健康个体中辨别患有和不患有ASCHD的牙周炎患者,并评估其与临床牙周参数和低密度脂蛋白(LDL)水平的相关性。该研究涉及120名参与者:30名是健康受试者(对照组,C),30例广泛性牙周炎(P组),30例患者有ASCHD和临床健康的牙周病(AS-C组),30例患有ASCHD和全身性牙周炎(AS-P组)。收集唾液和血液样本,和牙周特征,如菌斑指数,探查时出血,探测袋深度,并检查了临床附着丧失。IL-1β,使用ELISA测定来自唾液的IL-18和GSDMD水平。从血液样品中测定LDL水平。P组,AS-C,AS-P有较高水平的唾液IL-1β,IL-18和GSDMD高于C组。所有生物标志物的受试者工作特征(ROC)曲线显示出较高的诊断准确性,与临床参数和LDL水平呈显著正相关。所研究的促炎介质与疾病严重程度之间观察到的相关性表明,这些生物标志物可以作为牙周炎和ASCHD等疾病进展的指标。
    Inflammatory illnesses, such as periodontitis and atherosclerotic coronary heart disease (ASCHD), trigger the production of pro-inflammatory mediators. The aim of this study was to assess the accuracy of using salivary interleukin-1β (IL-1β), interleukin-18 (IL-18), and gasdermin D (GSDMD) in discerning patients with periodontitis with and without ASCHD from healthy individuals, and to assess their correlation with clinical periodontal parameters and low-density lipoprotein (LDL) levels. The study involved 120 participants: 30 were healthy subjects (control group, C), 30 had generalized periodontitis (group P), 30 had ASCHD and clinically healthy periodontium (group AS-C), and 30 had ASCHD and generalized periodontitis (group AS-P). Saliva and blood samples were collected, and periodontal characteristics such as plaque index, bleeding on probing, probing pocket depth, and clinical attachment loss were examined. IL-1β, IL-18, and GSDMD levels from saliva were determined using ELISA. LDL levels were determined from the blood samples. Groups P, AS-C, and AS-P had higher levels of salivary IL-1β, IL-18, and GSDMD than group C. The receiver operating characteristic (ROC) curves of all biomarkers showed high diagnostic accuracy, with a significant positive correlation with the clinical parameters and LDL levels. The observed correlations between the studied pro-inflammatory mediators and disease severity suggest that these biomarkers could serve as indicators of disease progression in conditions such as periodontitis and ASCHD.

    未经批准:鱼腥草(L.)Vahl(莎草科)是一种草类草本植物,习惯性地在稻田中作为杂草繁殖,主要散布在南亚和东南亚的热带或亚热带国家,澳大利亚北部,和西非。传统上,该植物已被用作膏药的形式来治疗发烧。然而,没有关于其毒性特征的科学研究得到证实。
    UNASSIGNED:已经进行了这项研究,以确定从鱼尾草叶中提取的甲醇提取物的潜在毒性,在小鼠中采用急性和亚慢性口服给药技术。
    UNASSIGNED:在根据OECD指南425的急性毒性研究中,在两种性别的瑞士白化病小鼠中以2000和5000mg/kg的单剂量口服FM甲醇提取物。有毒症状,异常行为,体重的变化,和死亡率观察连续14天。在根据OECD指南407的亚慢性毒性研究中,植物提取物以每天100、500、1000和2000mg/kg的剂量口服施用28天。一般的中毒症状,异常行为,每天观察体重变化。血清生化分析,研究结束时进行肝脏组织病理学检查。
    未经批准:无死亡,异常行为和排尿,睡眠的变化,食物摄入量,不利影响,在2000和5000mg/kg剂量的急性毒性研究中,已经记录了体重的非线性。此外,在亚慢性毒性研究中,FM提取物在一般行为方面没有产生死亡率或任何不利影响,体重,排尿,睡眠常规,和食物摄入。在分析十三个不同的生化参数的情况下,在急性和亚慢性研究中,雄性和雌性小鼠的天冬氨酸转氨酶(AST)和葡萄糖浓度均发生显着变化。总胆固醇和甘油三酯在5000mg/kg。在急性毒性研究中,雄性小鼠的bw发生变化。另一方面,雌性小鼠在亚慢性试验中改变了甘油三酯。发现所有其他关键参数未受影响。在亚慢性测试中,肝脏的组织病理学检查显示细胞坏死为2000mg/kg。bw在雄性和雌性小鼠中,而在1000mg/kg时观察到轻微的坏死。bw.因此,没有观察到的不良反应水平(NOAEL)可以假设在1000mg/kg左右。bw.
    未经证实:本研究表明,用FM提取物治疗未显示出明显的毒性。
    UNASSIGNED: Fimbristylis miliacea (L.) Vahl (Cyperaceae) is a grass like herb habitually breeds as weed in paddy fields and mostly disseminated in tropical or sub-tropical countries of south and south-east Asia, northern Australia, and west Africa. The plant has been traditionally used to treat fever as a form of poultice. However, no scientific study regarding its toxicity profile has been testified.
    UNASSIGNED: The study has been carried out to determine the potential toxicity of the methanol extract from leaves of the Fimbristylis miliacea, employing the technique of acute and subchronic oral administration in mice.
    UNASSIGNED: In the acute toxicity study according to OECD guideline 425, oral administration of FM methanol extract at single doses of 2000 and 5000 mg/kg in both sexes of Swiss albino mice was performed. Toxic symptoms, abnormal behavior, changes in body weight, and mortality were observed for 14 consecutive days. In subchronic toxicity study according to OECD guideline 407, plant extract was administered orally at doses of 100, 500, 1000, and 2000 mg/kg daily for 28 days. The general toxic symptoms, abnormal behavior, changes in body weight were observed daily. Biochemical analysis of serum, and histopathological examination of liver were performed at the end of the study.
    UNASSIGNED: No mortality, abnormal behavior and urination, changes in sleep, food intake, adverse effect, and non-linearity in body weight have been recorded during acute toxicity study at the doses of 2000 and 5000 mg/kg. Also, in subchronic toxicity study, FM extract produced no mortality or any kind of adverse effects in regards of general behavior, body weight, urination, sleeping routine, and food intake. In case of analysis of thirteen different biochemical parameters, concentrations of aspartate transaminase (AST) and glucose were altered significantly in male and female mice in both acute and subchronic study. Total cholesterol and triglycerides at 5000 mg/kg.bw were changed in male mice in acute toxicity study. On the other hand, female mice had altered triglycerides in subchronic test. All other critical parameters were found unaffected. In subchronic test, histopathological examination of liver demonstrated cellular necrosis at 2000 mg/kg.bw in both male and female mice while minor necrosis was observed at 1000 mg/kg.bw. Thus, the no observed adverse effect level (NOAEL) can be assumed around 1000 mg/kg.bw.
    UNASSIGNED: The present study suggests that treatment with FM extract does not reveal significant toxicity.

    冠状动脉疾病(CAD)是癌症幸存者心血管负担的重要原因。这篇综述确定了可以帮助指导有关筛查的益处的决策的特征,以评估亚临床CAD的风险或存在。根据危险因素和炎症负担,筛选可能适用于选定的幸存者。在接受基因检测的癌症幸存者中,多基因风险评分和克隆造血标志物可能成为未来有用的CAD风险预测工具。癌症的类型(尤其是乳腺癌,血液学,胃肠,和泌尿生殖系统)和治疗的性质(放射治疗,铂剂,氟尿嘧啶,激素治疗,酪氨酸激酶抑制剂,内皮生长因子抑制剂,和免疫检查点抑制剂)在确定风险方面也很重要。积极筛查的治疗意义包括生活方式和动脉粥样硬化干预,在特定情况下,可能需要进行血运重建。
    Coronary artery disease (CAD) is an important contributor to the cardiovascular burden in cancer survivors. This review identifies features that could help guide decisions about the benefit of screening to assess the risk or presence of subclinical CAD. Screening may be appropriate in selected survivors based on risk factors and inflammatory burden. In cancer survivors who have undergone genetic testing, polygenic risk scores and clonal hematopoiesis markers may become useful CAD risk prediction tools in the future. The type of cancer (especially breast, hematological, gastrointestinal, and genitourinary) and the nature of treatment (radiotherapy, platinum agents, fluorouracil, hormonal therapy, tyrosine kinase inhibitors, endothelial growth factor inhibitors, and immune checkpoint inhibitors) are also important in determining risk. Therapeutic implications of positive screening include lifestyle and atherosclerosis interventions, and in specific instances, revascularization may be indicated.

    未经证实:患有前列腺癌(PC)的男性心血管疾病(CVD)的发病率高于没有前列腺癌的男性。
    未经评估:我们描述了男性PC患者心血管危险因素控制不良的发生率和相关性。
    UNASSIGNED:我们对加拿大24个地点的2,811名连续男性(平均年龄68±8岁)进行了前瞻性表征,以色列,巴西,和澳大利亚。我们将总体风险因素控制不良定义为以下各项中的≥3:低密度脂蛋白胆固醇次优(如果Framingham风险评分[FRS]≥15,则>2mmol/L,如果FRS<15,则≥3.5mmol/L),目前的吸烟者,身体不活动(<600METmin/wk),次优血压(BP)(≥140/90mmHg,如果没有其他危险因素,如果已知CVD或FRS≥15,则收缩压≥120mmHg,如果糖尿病,则收缩压≥130/80mmHg),腰围:臀围比>0.9。
    未经评估:在参与者中(9%患有转移性PC,23%患有预先存在的CVD),99%有≥1个未控制的心血管危险因素,51%的患者总体危险因素控制不佳。不服用他汀类药物(优势比[OR]:2.55;95%CI:2.00-3.26),身体虚弱(OR:2.37;95%CI:1.51-3.71),需要BP药物(OR:2.36;95%CI:1.84-3.03),和年龄(每10年增加的OR:1.34;95%CI:1.14-1.59)与调整教育后总体风险因素控制不佳相关,PC特性,雄激素剥夺疗法,抑郁症,和东部肿瘤协作组的功能状态。
    未经评估:可改变的心血管危险因素控制不良在患有PC的男性中很常见,强调该人群在护理方面的巨大差距以及需要改进干预措施以优化心血管风险管理。
    UNASSIGNED: Cardiovascular disease (CVD) incidence is higher in men with prostate cancer (PC) than without.
    UNASSIGNED: We describe the rate and correlates of poor cardiovascular risk factor control among men with PC.
    UNASSIGNED: We prospectively characterized 2,811 consecutive men (mean age 68 ± 8 years) with PC from 24 sites in Canada, Israel, Brazil, and Australia. We defined poor overall risk factor control as ≥3 of the following: suboptimal low-density lipoprotein cholesterol (>2 mmol/L if Framingham Risk Score [FRS] ≥15 and ≥3.5 mmol/L if FRS <15), current smoker, physical inactivity (<600 MET min/wk), suboptimal blood pressure (BP) (≥140/90 mm Hg if no other risk factors, systolic BP ≥120 mm Hg if known CVD or FRS ≥15, and ≥130/80 mm Hg if diabetic), and waist:hip ratio >0.9.
    UNASSIGNED: Among participants (9% with metastatic PC and 23% with pre-existing CVD), 99% had ≥1 uncontrolled cardiovascular risk factor, and 51% had poor overall risk factor control. Not taking a statin (odds ratio [OR]: 2.55; 95% CI: 2.00-3.26), physical frailty (OR: 2.37; 95% CI: 1.51-3.71), need for BP drugs (OR: 2.36; 95% CI: 1.84-3.03), and age (OR per 10-year increase: 1.34; 95% CI: 1.14-1.59) were associated with poor overall risk factor control after adjustment for education, PC characteristics, androgen deprivation therapy, depression, and Eastern Cooperative Oncology Group functional status.
    UNASSIGNED: Poor control of modifiable cardiovascular risk factors is common in men with PC, highlighting the large gap in care and the need for improved interventions to optimize cardiovascular risk management in this population.

    未经证实:致病性突变与家族性高胆固醇血症(FH)患者的不良预后相关。然而,关于健康生活方式对FH表型影响的数据有限.
    未经证实:作者研究了健康的生活方式和FH突变与FH患者预后之间的相互作用。
    未经评估:我们调查了基因型与生活方式之间相互作用的关联,随着主要不良心脏事件(MACE)的发生,如心血管相关死亡率,心肌梗塞,不稳定型心绞痛,冠状动脉血运重建,在FH患者中。我们根据4份问卷评估了他们的生活方式(健康膳食模式,定期锻炼,不吸烟,和没有肥胖)。Cox比例风险模型用于评估MACE的风险。
    UNASSIGNED:中位随访时间为12.6(IQR:9.5-17.9)年。在随访期间,观察到179MACE。独立于经典的风险因素,FH突变和生活方式评分与MACE显著相关(HR:2.73;95%CI:1.03-4.43;P=0.02;HR:0.69,95%CI:0.40-0.98,P=0.033)。根据生活方式的不同,75岁的冠状动脉疾病的估计风险各不相同。从有良好生活方式的非携带者的21.0%到有不利生活方式的非携带者的32.1%,从有良好生活方式的携带者的29.0%到有不利生活方式的携带者的55.4%。
    UNASSIGNED:在有或没有基因诊断的FH患者中,健康的生活方式与MACE风险降低相关。
    UNASSIGNED: Pathogenic mutations are associated with poor outcomes in patients with familial hypercholesterolemia (FH). However, data on the effects of a healthy lifestyle on FH phenotypes are limited.
    UNASSIGNED: The authors investigated the interaction between a healthy lifestyle and FH mutation with prognosis in patients with FH.
    UNASSIGNED: We investigated the associations of the interaction between genotypes and lifestyle, with the occurrence of major adverse cardiac events (MACE), such as cardiovascular-related mortality, myocardial infarction, unstable angina, and coronary artery revascularization, in patients with FH. We assessed their lifestyle based on 4 questionnaires (healthy dietary pattern, regular exercise, not smoking, and absence of obesity). The Cox proportional hazards model was used to assess the risk for MACE.
    UNASSIGNED: The median follow-up duration was 12.6 (IQR: 9.5-17.9) years. During the follow-up duration, 179 MACE were observed. Independent of classic risk factors, FH mutation and lifestyle score were significantly associated with MACE (HR: 2.73; 95% CI: 1.03-4.43; P = 0.02; and HR: 0.69, 95% CI: 0.40-0.98, P = 0.033, respectively). The estimated risk of coronary artery disease by 75 years of age varied according to lifestyle, ranging from 21.0% among noncarriers with a favorable lifestyle to 32.1% among noncarriers with an unfavorable lifestyle and ranging from 29.0% among carriers with a favorable lifestyle to 55.4% among carriers with an unfavorable lifestyle.
    UNASSIGNED: A healthy lifestyle was associated with reduced risk for MACE among patients with FH with or without genetic diagnosis.

    未经证实:据报道,普伐他汀钠在脑动脉粥样硬化和神经元损伤中具有多种有益作用;然而,对脑静脉缺血的预防作用尚不清楚。在这里,我们旨在研究普伐他汀钠经口预先给药对大脑皮质静脉缺血并抑制细胞凋亡的神经保护作用。
    UNASSIGNED:将30只8周龄雄性Wistar大鼠平均分为两个研究组(n=15vs.n=15);普伐他汀组以其常规饮食喂养1%普伐他汀钠2周,而对照组只接受常规饮食。本研究采用两静脉闭塞(2VO)模型,每只动物的两个相邻的皮质静脉被玫瑰孟加拉染料光化学永久封闭。在光血栓形成期间,记录静脉缺血区域的脑血流量(CBF)的区域变化。2VO后48小时,使用灌注固定对动物实施安乐死,我们从组织学上测量了梗死面积与对侧半球的比率,并计数半影中的Bax和Bcl-2阳性细胞以研究其对细胞凋亡的意义。
    UNASSIGNED:普伐他汀组梗死面积比对照组明显降低(P<0.01)。普伐他汀组Bax阳性细胞数也显著减少(P<0.01)。相比之下,在两组的所有区域中,Bcl-2的免疫标记基本上为阴性。2VO后两组的区域CBF变化也没有显着差异(P=0.13)。
    UNASSIGNED:预先给予食物中混合的普伐他汀钠对大脑皮质静脉缺血具有神经保护作用,抑制与抑制Bax表达相关的细胞凋亡,但对局部CBF影响很小。
    UNASSIGNED: Pravastatin sodium is reported to have multiple beneficial effects in cerebral atherosclerosis and neuronal injury; however, the preventive effects on cerebral venous ischemia are still unknown. Herein, we aimed to examine the neuroprotective effects of transoral prior administration of pravastatin sodium against cerebral cortical venous ischemia with suppression of apoptosis.
    UNASSIGNED: Thirty 8-week-old male Wistar rats were divided equally into two study groups (n = 15 vs. n = 15); the pravastatin group was fed 1% pravastatin sodium with their usual diet for 2 weeks, while the control group only received the usual diet. Two-vein occlusion (2VO) model was applied for this study, and two adjacent cortical veins in each animal were permanently occluded photochemically with rose bengal dye. During photo-thrombosis, regional changes of the cerebral blood flow (CBF) in area of the venous ischemia were recorded. At 48-h after 2VO, animals were euthanized using perfusion fixation, and we histologically measured ratios of infarcted area to contralateral hemisphere, and counted Bax- and Bcl-2-positive cells in the penumbra to investigate the implications for apoptosis.
    UNASSIGNED: The ratio of infarcted area was significantly decreased in the pravastatin group compared to the control group (P < 0.01). The number of Bax-positive cells also decreased significantly in the pravastatin group (P < 0.01). In contrast, immunolabeling for Bcl-2 was essentially negative in all areas in both groups. There were also no significant differences in regional CBF changes after 2VO between the two groups (P = 0.13).
    UNASSIGNED: Pre-emptive administration of pravastatin sodium mixed in the food has neuroprotective effects against cerebral cortical venous ischemia with suppression of apoptosis associated with inhibition of Bax expression but has little influence on regional CBF.

    未经证实:先兆子痫(PE)与心血管疾病的终生风险增加有关。高密度脂蛋白(HDL)的主要保护功能之一是其在胆固醇反向转运中的作用。患有PE的妇女在怀孕期间HDL介导的胆固醇流出能力(CEC)降低。产后这种情况是否持续未知。
    UNASSIGNED:在正常血压(n=44)或PE(n=42)妊娠的妇女产后6个月确定基底和转运蛋白特异性CEC。还在23名正常血压和20名PE妇女中测量了CEC,这些妇女在产后24个月收集了样本。基础,主要使用稳定表达人ABCA1或ABCG1的中国仓鼠卵巢细胞测定ATP结合盒转运蛋白A1(ABCA1)-和-G1(ABCG1)-特异性CEC,并且还使用J774小鼠巨噬细胞系进行评估。
    UNASSIGNED:在产后6个月患有PE的女性中,ABCA1特异性CEC显着降低(0.57±0.1vs0.53±0.08;p<0.05),而基础和ABCG1特异性外排没有显着差异。PE后6个月,J774细胞的cAMP特异性CEC也较低(0.85±0.21vs0.75±0.25,p<0.05)。虽然apoA-I,apoE,与对照组相比,患有PE的女性的纤溶酶原和PON-1水平没有显着差异,ABCA1外排确实与apoA-1相关,HDL-C和apoE水平正常后,以及PE妊娠后apoA-1和HDL-C水平。ABCA1特异性外排在产后6至24个月的所有女性中减少,妊娠血压正常的女性为11±1.6%,PE女性为9±1.3%。调整apoA-I水平后,随着时间的推移,两组在产后6个月和血压正常的女性之间的ABCA1特异性外排没有显着差异,但在6至24个月之间,PE女性仍然存在显着差异。
    UnASSIGNED:ABCA1介导的CEC在PE妊娠后6个月受损,此后在正常血压和PE妊娠中均下降。ABCA1介导的外排在妊娠后是动态的,但不太可能解释PE女性长期增加的CVD风险。
    UNASSIGNED: Preeclampsia (PE) is associated with life-long increased risk of cardiovascular disease. One of the main protective functions of high-density lipoprotein (HDL) is its role in reverse cholesterol transport. HDL-mediated cholesterol efflux capacity (CEC) is decreased during pregnancy in women with PE. Whether this persists postpartum is unknown.
    UNASSIGNED: Basal and transporter-specific CEC were determined 6 months postpartum in women who had a normotensive (n = 44) or a PE (n = 42) pregnancy. CEC was also measured in 23 normotensive and 20 PE women for whom samples were collected 24 months postpartum. Basal, ATP-binding cassette transporter-A1 (ABCA1)- and -G1 (ABCG1)-specific CEC were primarily determined using Chinese hamster ovary cells stably expressing human ABCA1 or ABCG1, and were also assessed using a J774 mouse macrophage cell line.
    UNASSIGNED: ABCA1-specific CEC was significantly lower in women who had PE 6 months postpartum (0.57 ± 0.1 vs 0.53 ± 0.08; p < 0.05), whilst basal and ABCG1-specific efflux were not significantly different. cAMP-specific CEC in J774 cells was also lower 6 months after PE (0.85 ± 0.21 vs 0.75 ± 0.25, p < 0.05). Although apoA-I, apoE, plasminogen and PON-1 levels were not significantly different in women who had PE compared with controls, ABCA1 efflux did correlate with apoA-l, HDL-C and apoE levels after a normal, and with apoA-l and HDL-C levels after a PE pregnancy. ABCA1-specific efflux decreased in all women between 6 and 24 months postpartum, by 11 ± 1.6% in women who had a normotensive pregnancy and 9 ± 1.3% in women who had PE. After adjustment for apoA-I levels, there was no significant difference in ABCA1-specific efflux between the groups at 6 months postpartum and in normotensive women over time, but remained significantly different between 6 and 24 months in women who had PE.
    UNASSIGNED: ABCA1-mediated CEC is impaired 6 months postpartum after a PE pregnancy and decreases thereafter in both normotensive and PE pregnancies. ABCA1-mediated efflux is dynamic after pregnancy but is unlikely to explain the long-term increased CVD risk in women with PE.

    未经证实:主要心血管疾病(CVD)危险因素的患病率较低,如血脂异常,高血压和吸烟,可以解释西方国家过去几十年来心血管疾病死亡率和发病率下降的很大一部分。然而,一些研究表明,近年来风险因素的趋势较差。我们评估了2001年至2019年挪威年轻人血脂分布的时间趋势。
    未经证实:在奥斯陆一家大型医学实验室分析的血清脂质样本,挪威,主要由初级保健医生征用,进行了横断面分析,以估计18-49岁男性和女性的逐年趋势。我们还评估了脂质分布和比例与不良脂质水平。
    未经批准:总共,超过2600万份血液样本,包括来自挪威所有地区的100多万人(平均年龄37.7岁)。男女各年龄组的所有措施都有所改善,尤其是总胆固醇和非HDL胆固醇(每十年-0.22和-0.25mmol/l,分别)。总体人口分布有下降趋势,非HDL-C和LDL-C总胆固醇≥5.0mmol/l和非HDL-C≥3.9mmol/l的总体患病率相似地降低,从65%到46%,从52%到34%,分别。2019年,超过1/3的总HDL-C和/或非HDL-C水平升高。
    UNASSIGNED:在18-49岁的挪威人口中,在过去的二十年中,血脂状况有所改善。由于这个年龄组的降脂药物使用率较低,这可能反映了有利的长期趋势。
    UNASSIGNED: Lower prevalence of major cardiovascular disease (CVD) risk factors, such as dyslipidemia, hypertension and smoking, can explain a substantial part of the decline in CVD mortality and incidence for the past decades in Western countries. However, some studies have indicated less favorable trends in risk factors in recent years. We have assessed time trends in lipid profiles among young adults in Norway measured between 2001 and 2019.
    UNASSIGNED: Samples of serum lipids analyzed at one large medical laboratory in Oslo, Norway, mainly requisitioned by primary care physicians, were analyzed cross-sectionally to estimate year-to-year trends among men and women aged 18-49 years. We also assessed the lipid distributions and proportions with adverse lipid levels.
    UNASSIGNED: In total, more than 2,6 million blood samples, comprising more than 1 million individuals (mean age 37.7 years) from all regions of Norway were included. All measures improved among all age groups in both women and men, especially in total and non-HDL cholesterol (-0.22 and -0.25 mmol/l per decade, respectively). There were downward shifts in the population distribution of total, non-HDL-C and LDL-C. The overall prevalences of total cholesterol ≥5.0 mmol/l and non-HDL-C ≥3.9 mmol/l similarly decreased, from ∼63 to 46% and from ∼52 to 34%, respectively. More than 1/3 had elevated levels of total and/or non-HDL-C in 2019.
    UNASSIGNED: In a large proportion of the Norwegian population aged 18-49 years old, the lipid profiles improved during the last two decades. As the use of lipid-lowering medications is low in this age group, this likely reflects favorable secular trends.

    近年来,新的尼古丁输送方法已经出现,和许多用户正在选择电子香烟(电子香烟)而不是传统的烟草香烟。电子烟的使用在青少年中非常流行,目前在美国有超过350万人使用这些产品。尽管电子烟的使用越来越普遍,关于电子烟对一般人群的健康影响的知识有限。根据其他人发表的发现,电子烟与肺损伤爆发有关,这增加了与消费该产品相关的健康和安全问题。电子烟的不同成分,包括食品安全液体溶剂和调味剂,会导致与肺炎有关的健康问题,肺损伤,还有细支气管炎.此外,电子烟含有惊人的高水平的致癌物质和有毒物质,可能对其他器官系统有长期的影响,包括神经表现的发展,肺癌,心血管疾病,和蛀牙。尽管有据可查的潜在危害,电子烟似乎不会增加对SARS-CoV-2感染的易感性。此外,一些研究发现,电子烟使用者的肺部健康状况有所改善,副作用最小。因此,需要更多的研究来提供关于电子烟长期安全性的明确结论.这篇评论的目的是让读者了解与使用电子烟相关的可能的健康风险,特别是在年轻人和年轻人群体中,从分子生物学的角度来看。
    In recent years, new nicotine delivery methods have emerged, and many users are choosing electronic cigarettes (e-cigarettes) over traditional tobacco cigarettes. E-cigarette use is very popular among adolescents, with more than 3.5 million currently using these products in the US. Despite the increased prevalence of e-cigarette use, there is limited knowledge regarding the health impact of e-cigarettes on the general population. Based on published findings by others, E-cigarette is associated with lung injury outbreak, which increased health and safety concerns related to consuming this product. Different components of e-cigarettes, including food-safe liquid solvents and flavorings, can cause health issues related to pneumonia, pulmonary injury, and bronchiolitis. In addition, e-cigarettes contain alarmingly high levels of carcinogens and toxicants that may have long-lasting effects on other organ systems, including the development of neurological manifestations, lung cancer, cardiovascular disorders, and tooth decay. Despite the well- documented potential for harm, e-cigarettes do not appear to increase susceptibility to SARS-CoV- 2 infection. Furthermore, some studies have found that e-cigarette users experience improvements in lung health and minimal adverse effects. Therefore, more studies are needed to provide a definitive conclusion on the long-term safety of e-cigarettes. The purpose of this review is to inform the readers about the possible health-risks associated with the use of e-cigarettes, especially among the group of young and young-adults, from a molecular biology point of view.

  • 文章类型: Journal Article
    未经授权:微囊性黄斑水肿(MME),也称为逆行性黄斑病(RM),由于一系列原因,与严重的视神经萎缩有关。然而,在原发性视网膜病理中也描述了类似的变化,并且对MME的发病机制存在争议。
    UNASSIGNED:回顾性观察病例系列。
    未经证实:非动脉炎性缺血性视神经病变患者。
    UNASSIGNED:在列日大学医院进行了回顾性观察病例系列,比利时。被转诊到我们神经眼科诊断为非动脉炎性前部缺血性视神经病变(NA-AION)的患者的病历,在2014年至2021年之间,进行了审查。
    未经鉴定:神经节细胞复合体厚度,急性和慢性内核变化。
    未经证实:在一组34名NA-AION患者(平均年龄:60±12.5岁;65.6%为男性)中,我们发现19只眼出现时与视盘肿胀相关的内核层(INL)短暂性微囊性改变.这种早期变化与源自视盘的视网膜内和视网膜下液的漏出有关。在出现这种短暂变化的患者中,3随后发展为MME,在观察期间保持固定(范围,12-34个月)。在没有早期INL短暂变化的患者中未观察到MME。在6个月时严重神经节细胞复合物变薄的患者中观察到微囊性黄斑水肿:上半毛平均(±SD)丢失(-28.2±5.2μm[-33.3%,范围,-22.3至-30.3μm])和下半毛(-30.7±5.6μm[-31.0%,范围,-24.3至34.8μm])。
    未经证实:我们的研究揭示了在经历NA-AION的相同患者中INL囊性改变的两种原因,一个是可逆的,另一个可能是永久性的。这一发现强调了与液体渗出有关的真正水肿(在这种情况下是缺血性视盘肿胀的继发)与RM中观察到的与视网膜神经纤维层/神经节细胞复合物变薄程度有关的现象之间的区别。INL的囊性改变与严重的视神经萎缩(MME)有关。然而,在视网膜病理学中已经描述了类似的变化,并且对MME的发病机制进行了辩论。
    UNASSIGNED: Microcystic macular edema (MME), also known as retrograde maculopathy (RM), is associated with severe optic atrophy because of a range of causes. However, similar changes have also been described in primary retinal pathology and the pathogenesis of MME is debated.
    UNASSIGNED: A retrospective observational case series.
    UNASSIGNED: Patients with nonarteritic ischemic optic neuropathy.
    UNASSIGNED: A retrospective observational case series was performed at the University Hospital of Liège, Belgium. The medical records of patients who were referred to our Neuro-ophthalmology department with a diagnosis of nonarteritic anterior ischemic optic neuropathy (NA-AION), between 2014 and 2021, were reviewed.
    UNASSIGNED: Ganglion cell complex thickness, acute and chronic inner nuclear change.
    UNASSIGNED: In a cohort of 34 patients (mean age: 60 ± 12.5 years; 65.6% men) with NA-AION, we identified a transient microcystic change in the inner nuclear layer (INL) associated with optic disc swelling in 19 eyes at presentation. This early change was associated with a transudate of intraretinal and subretinal fluid originating from the optic disc. Among patients who had shown this transient change 3 subsequently developed MME, which remained fixed during the period of observation (range, 12-34 months). No MME was observed in patients without an early INL transient change. Microcystic macular edema was observed in patients with severe ganglion cell complex thinning at 6 months: mean (± SD) loss in superior hemimacula (-28.2 ± 5.2 μm [-33.3%, range, -22.3 to -30.3 μm]) and in inferior hemimacula (-30.7 ± 5.6 μm [-31.0%, range, -24.3 to 34.8 μm]).
    UNASSIGNED: Our study has revealed 2 causes of INL cystic change in the same patients experiencing NA-AION, 1 reversible and the other likely permanent. This finding highlights the distinction between genuine edema related to transudation of fluid (in this case secondary to ischemic optic disc swelling) and the phenomenon observed in RM that is related to the degree of retinal nerve fiber layer/ganglion cell complex thinning. Cystic change in the INL is associated with severe optic atrophy (MME). However, similar changes have been described in retinal pathology and the pathogenesis of MME is debated.
