Partitioning heritability analyses unveil the genetic architecture of human brain multidimensional functional connectivity patterns

Resting‐state functional connectivity profiles have been increasingly shown to be important endophenotypes that are tightly linked to human cognitive functions and psychiatric diseases, yet the genetic architecture of this multidimensional trait is barely understood. Using a unique sample of 1,704 unrelated, young and healthy Chinese Han individuals, we revealed a significant heritability of functional connectivity patterns in the whole brain and several subnetworks. We further proposed a partitioned heritability analysis for multidimensional functional connectivity patterns, which revealed the common and unique enrichment patterns of the genetic contributions to brain connectivity patterns for several gene sets linked to brain functions, including the genes expressed preferentially in the central nervous system and those associated with intelligence, educational attainment, attention‐deficit/hyperactivity disorder, and schizophrenia. These results for the first time reveal the genetic architecture of multidimensional brain connectivity patterns across different networks and advance our understanding of the complex relationship between gene sets, neural networks, and behaviors.     

Influence of footwear on postural sway: A systematic review and meta-analysis on barefoot and shod bipedal static posturography in patients and healthy subjects

BackgroundBipedal static posturography is widely used to assess postural control. However, standardized methods and evidence on the influence of footwear on balance in comparison to barefoot stance is sparse.Research questionsIs bipedal static posturography applied in a standardized way with respect to demographics and the experimental set-up (systematic review)? Does habitual footwear influence postural control in comparison to barefoot condition during bipedal static posturography in adult patients and healthy subjects (meta-analysis)?MethodsFor this systematic review and meta-analysis, a comprehensive follow-up literature search was conducted from March 2009 until January 2020 according to the PRISMA guidelines. Original, research articles reporting on bipedal, unsupported, static posturography in adults (≥18 years) were included according to inclusion criteria (age, sex, height, weight, duration, repetitions, visual/foot condition, sampling frequency). Studies comparing habitual footwear with barefoot condition during bipedal static posturography were included for the meta-analysis. Center of pressure parameters (sway velocity, range, root mean square, paths lengths) with subjects having eyes closed (EC) or open (EO) were analyzed using random effects models.ResultsFor this systematic review and meta-analysis, 207 and eight out of 5189 studies with 12'341 and 156 subjects, respectively, were eligible. Most studies (89%) reported barefoot, 5% shod, and 6% barefoot and shod measurements. Less than half of studies (44%) included patients of which the minority (13%) suffered from neurological disease. Sway velocity in the anterior-posterior direction was higher in habitual shoes compared to barefoot with EC (SMD: 1.08; 95% CI: 0.68–1.48; p < 0.01; I² = 0%), with EO (SMD: 0.68; 95% CI: 0.11–1.26; p = 0.02; I² = 1%), and in the medio-lateral direction with EC (SMD: 1.30; 95% CI: 0.76–1.85, p < 0.01; I² = 37%).SignificanceMethodical heterogeneity of bipedal static posturography hampers studies’ comparability. Thus, we provide a standardized approach to increase knowledge whether habitual footwear decrease postural control in comparison to barefoot stance.     

关于改革完善重大疫情防控救治体系的建议

针对重大疫情防控救治，在系统梳理临床治疗、疾病控制和科学研究三者定位的基础上，结合本次新型冠状病毒肺炎疫情暴露出来的问题，提出了改革完善我国重大疫情防控救治体系的建议。临床治疗方面，要加强医务人员依法报告意识，强化症状检测能力，充分发挥传染病直报系统的作用，建立健全新发突发传染病的国家或地方监测平台。疾病控制方面，要从法律和体制机制上赋予疾控相关权限和保障，提升疾控队伍的数量和质量，加强防控与应急需求为导向的应用性研究和技术储备。科学研究方面，要加强以国家需求为导向的科研立项，建设重大疫情应对中“一锤定音”的科研机构，建立国家和区域传染病重点实验室，加强新发突发传染病防控救治的战略技术储备。     

上海市徐汇区45~55岁居民动脉粥样硬化性心血管疾病风险的影响因素分析

背景　动脉粥样硬化性心血管疾病（ASCVD）是我国居民健康的首要威胁，也是我国居民的首要死亡原因，占城市居民的41.8%，占农村居民的44.8%。家庭医生及其团队对社区中年人群相关风险因素的调研评估、干预及综合管理，可尽早预防ASCVD的发生发展。目的　调查上海市徐汇区45~55岁居民ASCVD风险因素，为日后对相关人群开展针对性的健康干预提供参考意见和建议。方法　采集2019年1-5月在上海市徐汇区枫林街道社区卫生服务中心门诊就诊、信息平台留存准确个人资料（性别、年龄、联系电话）及在本单位体检留存生理、生化数据〔身高、体质量、BMI、血压和血清总胆固醇（TC）、三酰甘油（TG）、高密度脂蛋白胆固醇（HDL-C）、低密度脂蛋白胆固醇（LDL-C）及空腹血糖（FPG）〕的530例居民的信息。采用电话回访或现场面对面调查，参照《中国成人血脂异常防治指南（2016年修订版）》中“总体心血管危险评估”相关章节内容定义ASCVD 风险，同时基于社区实际情况，将评估低危和中危人群归为ASCVD低风险组，高危和极高危人群归为ASCVD高风险组。采用多元Logistic逐步回归分析探究居民ASCVD风险的影响因素。结果　发放问卷530份，回收有效问卷502份，有效回收率为94.7%。ASCVD低风险组38例，ASCVD高风险组464例。ASCVD高风险组年龄、TG、FPG、男性比例、心脑血管病史比例、糖尿病史比例、高血压史比例、服用降压药史比例、服用调脂药史比例高于ASCVD低风险组（P<0.05）。多元Logistic逐步回归分析结果显示，≥50岁、TG≥1.5 mmol/L、FBG≥6.1 mmol/L、男性是居民ASCVD风险的危险因素（P<0.05）；服用调脂药史是居民ASCVD风险的保护因素（P<0.05）。结论　上海市徐汇区45~55岁居民ASCVD风险的主要可控危险因素是血脂（TG）及血糖的异常；不可控危险因素是年龄、性别。对于增龄、男性、合并脂代谢异常的居民更应关注ASCVD的风险并予以生活方式干预和调脂药规范使用指导。社区开展多重风险因素评估及管理对ASCVD的早期筛查、早期干预及治疗均非常重要，对家庭医生及其团队开展相关一、二级预防工作有指导借鉴意义。     

Preliminary Results on the Feasibility of Using ARFI/SWEI to Assess Cutaneous Sclerotic Diseases

In this study, acoustic radiation force impulse (ARFI) and shear wave elasticity imaging (SWEI) were applied to the skin to investigate the feasibility of their use in assessing sclerotic skin diseases. Our motivation was to develop a non-invasive imaging technology with real-time feedback of sclerotic skin disease diagnosis. This paper shows representative results from an ongoing study, recruiting patients with and without sclerosis. The stiffness of the imaged site was evaluated using two metrics: mean ARFI displacement magnitude and bulk shear wave speed inside the region of interest (ROI). In a subject with localized graft versus host disease (GVHD), the mean ARFI displacement inside sclerotic skin was 61% lower (p < 0.01) and shear wave speed 128% higher (p < 0.005) compared to those in normal skin—indicating stiffer mechanical properties in the sclerotic skin. This trend persisted through disease types. We conclude ARFI and SWEI can successfully differentiate sclerotic lesions from normal dermis.
