Understanding the Influence of Nanocarrier-Mediated Brain Delivery on Therapeutic Performance Through Pharmacokinetic-Pharmacodynamic Modeling

This study aimed at evaluating how encapsulation in a regular nanocarrier (NC) (providing extended circulation time) or in a brain-targeting NC (providing prolonged circulation time and increased brain uptake) may influence the therapeutic index compared with the unformulated drug and to explore the key parameters affecting therapeutic performance using a model-based approach. Pharmacokinetic (PK) models were built with chosen PK parameters. For a scenario where central effect depends on area under the unbound brain concentration curve and peripheral toxicity relates to peak unbound plasma concentration, dose-effect and drug-side effect curves were constructed, and the therapeutic index was evaluated. Regular NC improved the therapeutic index compared with the unformulated drug due to reduced peripheral toxicity, while brain-targeting NC enhanced the therapeutic index by lowering peripheral toxicity and increasing central effect. Decreasing drug release rate or systemic clearance of NC with drug still encapsulated could increase the therapeutic index. Also, a drug with shorter half-life would therapeutically benefit more from a NC encapsulation. This work provides insights into how a NC for brain delivery should be optimized to maximize the therapeutic performance and is helpful to predict if and to what extent a drug with certain PK properties would obtain therapeutic benefit from nanoencapsulation.

A cross-sectional examination of sociodemographic factors associated with meeting physical activity recommendations in overweight and obese US adults

ObjectiveObesity has reached epidemic proportions in the US. Physical activity is an important component of obesity reduction, but little is known about contemporary exercise levels among overweight/obese American adults. In this study, we compared current physical activity levels in overweight and obese US adults to those of normal weight individuals as well as ascertained which sociodemographic factors influence the meeting of physical activity recommendations in these three groups.MethodsWe used national data from 2015 and 2017 Behavioral Risk Factor Surveillance System surveys (n = 726,075). Bivariate analyses were conducted to determine unadjusted physical activity levels in normal weight, overweight, and obese adults. We fit multinomial logistic models to identify associations between sociodemographic factors and meeting physical activity recommendations in our study population.ResultsAround 45% of overweight and 57% of obese adults failed to meet physical activity guidelines compared to 41% of normal weight adults. Age, sex, and race were significantly associated with physical activity levels for both overweight and obese adults. In overweight and obese individuals, associations between sociodemographic factors and physical activity were more similar between the two comparisons of insufficiently active (IA) versus active (A)/highly active (HA) and A versus HA but quite different to those in the inactive (IN) versus IA/A/HA comparison.ConclusionsFuture physical activity interventions should be aimed at increasing the number of overweight and obese US adults who meet physical activity guidelines as well as targeted towards specific sociodemographic groups within the overweight/obese population with low exercise levels.

老年轻度认知障碍患者血清瘦素、甲状腺激素水平与局部脑血流量关系的研究

目的 通过检测老年轻度认知障碍（MCI）患者血清瘦素（LEP）、甲状腺激素水平，分析其与局部脑血流量（rCBF）的关系。方法 选择本院收治的128 例老年MCI 患者，另选健康者128 例作为对照组。检测血清LEP、甲状腺激素、大脑各区域rCBF 水平并分析其相关性。结果 老年MCI 组患者左右侧额叶、右侧颞叶、左侧顶叶、左右侧基底节区域脑血流量[（43.81±8.62）mL/（100 g·min）、（43.24±7.93）mL/（100 g·min）、（45.14±6.98）mL/（100 g·min）、（45.86±6.77）mL/（100 g·min）、（67.95±8.52）mL/（100 g·min）、（68.36±8.34）mL/（100 g·min）]低于对照组[（46.39±8.31）mL/（100 g·min）、（46.52±8.56）mL/（100 g·min）、（47.37±7.04）mL/（100 g·min）、（48.25±6.98）mL/（100 g·min）、（70.34±8.96）mL/（100 g·min）、（70.58±8.57）mL/（100 g·min）]（P＜0.05）。老年MCI 组患者血清LEP、T3、FT3 水平[（4.87±1.56）μg/L、（1.21±0.16）nmol/L、（3.04±0.36）pmol/L]低于对照组[（11.45±3.92）μg/L、（1.68±0.21）nmol/L、（4.82±1.21）pmol/L]（P＜0.05），TSH 水平为（2.78±0.75）IU/mL，高于对照组的（1.13±0.38）IU/mL（P＜0.05）。老年MCI 患者血清LEP 水平与左侧额叶、右侧颞叶、左侧顶叶rCBF 呈正相关（r=0.452、0.537、0.544，P 均＜0.05），T3 水平与左侧额叶、右侧颞叶rCBF 呈正相关（r=0.427、0.521，P 均＜0.05），FT3 水平与右侧颞叶rCBF 呈正相关（r=0.492，P＜0.05），TSH 水平与左侧额叶、右侧颞叶rCBF 呈负相关（r=-0.463、-0.489，P 均＜0.05）。结论 老年MCI 患者血清中LEP、T3、FT3 水平降低，TSH 水平升高，且与不同区域rCBF 有相关性，可通过调控脑血管功能影响rCBF 变化水平。     

Association Between Patient and Physician Sex and Physician-Estimated Stroke and Bleeding Risks in Atrial Fibrillation

Background

Physicians treating nonvalvular atrial fibrillation (AF) assess stroke and bleeding risks when deciding on anticoagulation. The agreement between empirical and physician-estimated risks is unclear. Furthermore, the association between patient and physician sex and anticoagulation decision-making is uncertain.

四方联动防跌护理在社区跌倒高危老年人中的应用

目的探讨专科护士-社区护士-个体-家庭四方联动防跌护理模式在社区跌倒高危老年人中的应用与效果。方法选取深圳市龙岗区的2个社区,随机分为观察组和对照组,从两个社区登记建档的跌倒高风险老年居民中分别随机抽选45名进行干预。观察组采用"专科护士-社区护士-个体-家庭"四方联动推进的综合干预方案。对照组接受社区防跌倒常规护理。于干预前及干预后12个月使用修订版社区老年人跌倒危险评估量表、步态和平衡测试量表对两组老年人进行评测,记录两组1年内跌倒发生例次。结果干预期间跌倒发生情况:观察组1人次,对照组6人次。观察组步态和平衡测试得分提高,跌倒危险评估表得分降低,与对照组比较,差异有统计学意义(均P0.01)。结论四方联动的综合干预方案应用于社区居家老年人,能有效降低老年人跌倒风险,提升其防跌能力,对预防社区老年人跌倒的发生有积极作用。     

OTC drug advertising in Japan: the role of need for cognition and celebrity endorser credibility

Abstract

This research explores how the level of consumers’ need for cognition (NFC) is associated with celebrity endorser credibility and examines its effects on advertising-related attitudes. A 3 (endorser types: actor/actress, athlete, TV personality/talent) × 2 (endorser’s gender) factorial experiment with 435 Japanese consumers was conducted. Concerning Japanese OTC drug advertising, lower NFC individuals perceived celebrity endorsers as more credible in comparison to higher NFC individuals. The main effects of NFC and endorser type on endorser credibility existed; however, no interaction between the two variables was found. The endorser type had an influence on attitudes toward ads and the advertised brand.
