Skin Protection for (SPF) Kids Program

Skin cancer is increasing faster than any other cancer in the United States. Individuals who have had excessive sun exposure during childhood and adolescence set the stage for the development of skin cancers later in life. In 2009, there were more than 1 million newly diagnosed cases of skin cancer in the United States. This primary prevention program combined the guidelines in the literature resulting in a unique evidence-based program for teachers and informational guidelines for parents. These guidelines were used in classrooms and at home, supporting intervention among school-age children, specifically those in kindergarten through fifth grade.

Association Between Cardiorespiratory Fitness and Risk of Heart Failure: A Meta-Analysis

BackgroundEvidence emerges that cardiorespiratory fitness (CRF) might be implicated in the development of heart failure (HF). This meta-analysis aimed to quantify the association between CRF exposed at baseline and HF risk with dose–response analysis and to assess whether CRF changes over time are correlated with alterations in HF risk.Methods and ResultsCohort studies that assessed the association between CRF and risk of HF in subjects without baseline HF were included. Study-specific multivariate-adjusted relative risks (RRs) with 95% confidence intervals (CIs) were pooled using a random-effects model. Ten studies from 8 articles were included, enrolling 8987 incident HF cases from 154,598 participants. The RR of HF per 1-metabolic equivalent (MET) higher CRF at baseline was 0.82 (95% CI 0.80–0.84) in the overall population. The RRs were similar in men (0.82, 95% CI 0.80–0.85) and women (0.81, 95% CI 0.78–0.84), and remained minorly changed in patients with existing diabetes, hypertension, or cardiovascular disease at entry. No evidence of a nonlinear relationship between CRF at baseline and risk of HF was observed (P_nonlinearity = .18). The RR of HF per 1-MET increase in CRF over time was 0.79 (95% CI 0.67–0.93), and the measurement of CRF provided incremental value to the prediction of HF beyond conventional models.ConclusionsHigh or increased CRF resulted in reduced risk of HF in a dose-dependent manner, supporting the necessity to increase CRF to prevent HF in clinical practice.     

浅低温不停循环优先重建弓部血管结合术中支架阻断技术与传统孙氏手术的对比研究

目的:采用浅低温不停循环优先重建弓部血管结合术中支架阻断技术治疗急性Stanford A型主动脉夹层,并与传统孙氏手术进行比较,评估其效果和安全性。方法:回顾性分析2017年1月至2018年12月山东省临沂市人民医院心脏血管外科手术治疗的40例急性A型主动脉夹层患者的资料,其中21例在浅低温不停循环下,采用优先重建弓部血管结合术中支架阻断技术进行改良的孙氏手术治疗,19例采用传统的孙氏手术治疗。统计分析患者术中、术后的相关指标及并发症情况。结果:与传统的孙氏手术相比,改良组在术中阻断时间[(218.63±27.86)min比(101.52±17.23)min]、停循环时间[(1174.74±183.65)s比(43.19±8.32)s]、体外循环时间[(218.63±27.86)min比(194.19±24.25)min]、术后并发症(14次比6次)、术后呼吸机辅助时间[(72.89±45.57)h比(29.86±32.3)h]及围术期输血量[(1332.63±301.55)ml比(991.90±323.23)ml]等方面存在明显优势,差异有统计学意义(P均<0.05)。手术后清醒时间方面,改良组优于传统组,但差异无统计学意义。结论:采用浅低温不停循环优先重建弓部血管结合术中支架阻断技术治疗急性A型主动脉夹层是安全、有效的,可以明显改善患者预后,减少并发症的发生。     

面部敏感性皮肤防晒化妆品的筛选与评价

【摘要】 目的 对面部敏感性皮肤防晒化妆品进行筛选与评价。方法 2019年6 - 8月在重庆市中医院职工中招募40例乳酸刺痛试验阳性者作为研究对象，分别进行4种敏感性皮肤用防晒化妆品（标记为产品Ⅰ、Ⅱ、Ⅲ、Ⅳ）的人体皮肤封闭型斑贴试验。将40例受试者平均分为2组，分别于面部使用安全性较高的2种产品，于使用前、使用后2周和4周评估红斑、水肿、脱屑情况，采用仪器无创检测经皮水分丢失、皮肤角质层含水量、皮肤黑素含量、皮肤油脂含量。分别于受试者背部涂上述2种产品，采用紫外日光模拟仪进行防晒指数（SPF，12例）及长波紫外线防护指数（PFA，11例）测定。计量资料采用配对t检验和单因素方差分析比较；非参数资料采用Wilcoxon符号秩检验比较。结果 斑贴试验显示，防晒产品Ⅲ仅发生1例1级反应，产品Ⅳ未发生阳性反应，安全性高于另外2款产品。主观安全性评价显示，使用产品Ⅲ、Ⅳ4周时红斑程度均低于使用前（Wilcoxon符号秩检验，Z = 4.73、4.82，均P < 0.05）。客观功效性评价显示，使用防晒产品Ⅲ、Ⅳ前及使用2周、4周时表皮失水率、角质层含水量、黑素含量差异均有统计学意义（均P < 0.05）；使用产品Ⅲ、Ⅳ4周时表皮失水率（30.05 ± 1.47、30.37 ± 1.28）、黑素含量（112.58 ± 7.34、103.47 ± 5.48）均低于使用前（均P < 0.05），角质层含水量（62.35 ± 2.67、63.72 ± 2.54）均高于使用前（均P < 0.05）。使用4周时，产品Ⅳ组黑素含量（103.47 ± 5.48）与产品Ⅲ组（112.58 ± 7.34）比较，差异有统计学意义（t = 8.45，P < 0.05）。产品ⅣSPF值、PFA值（51.8 ± 2.9、10.1 ± 1.2）均高于产品Ⅲ（31.5 ± 2.6、7.4 ± 0.7，t = 15.34、24.66，均P < 0.05）。结论 综合应用封闭型斑贴实验、长期试用试验、防晒指数测定等方法可评价面部敏感性皮肤防晒化妆品的安全性和防晒功效。
