    背景:关于自闭症儿童的大脑如何在现实世界的社会环境中处理语言,人们知之甚少。“尽管语言的挑战,通信,和社交互动是自闭症谱系障碍(ASD)的核心特征。方法:我们调查了N=20个自闭症患者和N=20个神经典型(NT)学龄前儿童样本中社会和非社会环境中语言处理的神经基础,3到6岁。功能近红外光谱(fNIRS)用于测量儿童在现场社交环境中对现场实验者所说的“现场语言”的大脑反应(即,书籍阅读),以及在非社交环境中通过录音播放的“录音语言”(即,屏幕时间)。我们检查了组内和组间对现场语言和记录语言的大脑反应的强度和定位差异,以及通过学龄前语言量表测量的儿童大脑反应与语言技能之间的相关性。结果:NT组,在右颞顶叶交界处(TPJ),大脑对实时语言的反应大于对记录语言的反应。在ASD组中,不同条件下的大脑反应强度没有差异。在右下额中回(IMFG)中,ASD组对记录语言的大脑反应比NT组强。跨群体,儿童的语言技能与大脑对右侧IMFG记录语言的反应呈负相关,这表明,对于语言技能较低的儿童,处理记录的语言需要更多的认知努力。在正确的TPJ中,儿童的语言技能也与大脑反应的差异呈正相关,表明,与记录语言相比,大脑对现场语言的反应差异更大的儿童具有更高的语言技能。局限性:研究结果应被认为是初步的,直到它们在更大的样本中被复制。结论:研究结果表明,NT儿童的大脑,但不是自闭症儿童,在社会和非社会环境中不同地处理语言。在社会和非社会环境中大脑如何处理语言的个体差异可能有助于解释为什么有和没有自闭症的儿童的语言技能如此多变。
    UNASSIGNED: Little is known about how the brains of autistic children process language during real-world \"social contexts,\" despite the fact that challenges with language, communication, and social interaction are core features of Autism Spectrum Disorder (ASD).
    UNASSIGNED: We investigated the neural bases of language processing during social and non-social contexts in a sample of N=20 autistic and N=20 neurotypical (NT) preschool-aged children, 3 to 6 years old. Functional near-infrared spectroscopy (fNIRS) was used to measure children\'s brain response to \"live language\" spoken by a live experimenter during an in-person social context (i.e., book reading), and \"recorded language\" played via an audio recording during a non-social context (i.e., screen time). We examined within-group and between-group differences in the strength and localization of brain response to live language and recorded language, as well as correlations between children\'s brain response and language skills measured by the Preschool Language Scales.
    UNASSIGNED: In the NT group, brain response to live language was greater than brain response to recorded language in the right temporal parietal junction (TPJ). In the ASD group, the strength of brain response did not differ between conditions. The ASD group showed greater brain response to recorded language than the NT group in the right inferior and middle frontal gyrus (IMFG). Across groups, children\'s language skills were negatively associated with brain response to recorded language in the right IMFG, suggesting that processing recorded language required more cognitive effort for children with lower language skills. Children\'s language skills were also positively associated with the difference in brain response between conditions in the right TPJ, demonstrating that children who showed a greater difference in brain response to live language versus recorded language had higher language skills.
    UNASSIGNED: Findings should be considered preliminary until they are replicated in a larger sample.
    UNASSIGNED: Findings suggest that the brains of NT children, but not autistic children, process language differently during social and non-social contexts. Individual differences in how the brain processes language during social and non-social contexts may help to explain why language skills are so variable across children with and without autism.

    目前的SARS-CoV-2疫苗为COVID-19相关的住院和死亡提供保护,但在抑制初始感染和传播方面仍然效率低下。尽管更新了助推器配方,新出现的SARS-CoV-2变种的突破性感染和再感染很常见。鼻内接种以引起感染部位的粘膜免疫可以改善呼吸道病毒疫苗的性能。我们开发了SARS-CoV-2M2SR,SARS-CoV-2和流感疫苗的双重候选,使用我们的活的鼻内M2缺陷型单复制(M2SR)流感载体,表达原型菌株的SARS-CoV-2刺突蛋白的受体结合域(RBD),首次报道于2020年1月。用这种双重疫苗对小鼠的鼻内接种引起对RBD的高血清IgG和粘膜IgA滴度。接种小鼠的血清显示,接种疫苗的小鼠产生了针对原型和Delta病毒株的中和SARS-CoV-2抗体滴度,被认为足以防止病毒感染。此外,SARS-CoV-2M2SR引起了对OmicronBA.4/BA.5变体的交叉反应性血清和粘膜抗体。SARS-CoV-2M2SR疫苗还维持了对甲型流感的强免疫应答,具有高滴度的抗H3血清IgG和血凝抑制(HAI)抗体滴度,其对应于单独从对照M2SR载体观察到的那些。在人类中具有可靠的安全记录和强大的免疫学特征,包括粘膜免疫,表达关键SARS-CoV-2抗原的M2SR流感病毒载体可以提供更有效的针对流感和SARS-CoV-2变体的保护。
    Current SARS-CoV-2 vaccines provide protection for COVID-19-associated hospitalization and death, but remain inefficient at inhibiting initial infection and transmission. Despite updated booster formulations, breakthrough infections and reinfections from emerging SARS-CoV-2 variants are common. Intranasal vaccination to elicit mucosal immunity at the site of infection can improve the performance of respiratory virus vaccines. We developed SARS-CoV-2 M2SR, a dual SARS-CoV-2 and influenza vaccine candidate, employing our live intranasal M2-deficient single replication (M2SR) influenza vector expressing the receptor binding domain (RBD) of the SARS-CoV-2 Spike protein of the prototype strain, first reported in January 2020. The intranasal vaccination of mice with this dual vaccine elicits both high serum IgG and mucosal IgA titers to RBD. Sera from inoculated mice show that vaccinated mice develop neutralizing SARS-CoV-2 antibody titers against the prototype and Delta virus strains, which are considered to be sufficient to protect against viral infection. Moreover, SARS-CoV-2 M2SR elicited cross-reactive serum and mucosal antibodies to the Omicron BA.4/BA.5 variant. The SARS-CoV-2 M2SR vaccine also maintained strong immune responses to influenza A with high titers of anti H3 serum IgG and hemagglutination inhibition (HAI) antibody titers corresponding to those seen from the control M2SR vector alone. With a proven safety record and robust immunological profile in humans that includes mucosal immunity, the M2SR influenza viral vector expressing key SARS-CoV-2 antigens could provide more efficient protection against influenza and SARS-CoV-2 variants.

    该研究旨在确定将存在的发现的潜在机制,活,生存和战斗(WTELS-F)优化执行功能。将执行功能(EF)定义为具有冷(工作记忆,抑制,和认知灵活性)和热(例如,动机)组件,我们假设WTELS-F通过两条途径积极影响执行功能。第一个途径是通过热执行功能(动机),第二种是通过生存或存在的处理。在对228名成年参与者进行的两次纵向研究中,其间有十周的时间,我们使用了WTELS-F的措施,工作记忆,抑制,移位/认知灵活性,和自我激励。我们通过在时间1数据中的探索性因素分析和在时间2数据中的验证性因素分析测试了四个因素的执行功能的结构效度。我们进行了结构方程建模,将WTELS-F的变化作为潜在变量,该潜在变量是通过其三个分量在时间1和2之间的变化来预测的。,影响自我激励(热EF)的变化,以及由工作记忆的变化所预测的冷EF潜在变量的变化,抑制,和转变。结果表明,EF模型在没有修改的情况下很好地拟合了数据。WTELS-F纵向显着影响自我动机(热EF)和冷EF。它通过对自我动机的影响进一步介导了对冷EF的影响。该结果为WTELS-F对EF影响的两条途径假说提供了证据。讨论了这些发现的概念和临床意义。
    The study aims to identify the mechanisms underlying the findings that will to exist, live, survive and fight (WTELS-F) optimizes executive functions. Defining executive functions (EF) as having cold (working memory, inhibition, and cognitive flexibility) and hot (e.g., motivation) components, we hypothesized that WTELS-F affects executive functions positively via two pathways. The first pathway is through the hot executive function (motivation), and the second is via survival or existential processing. In a longitudinal study of 228 adult participants two times with ten weeks in between, we used measures for WTELS-F, working memory, inhibition, shift/cognitive flexibility, and self-motivation. We tested the structural validity of the four factors\' executive function by exploratory factor analysis in time 1 data and confirmatory factor analysis in time 2 data. We conducted structural equation modeling WTELS-F change as a latent variable predicted by the change in its three components between times 1 and 2., affecting changes in self-motivation (the hot EF), and changes in the latent variable of cold EF as predicted by changes in working memory, inhibition, and shift. Results indicated that the model of EF fit the data well without modification. WTELS-F significantly affected self-motivation (the hot EF) and the cold EF longitudinally. It had further mediated effects on cold EF via its impact on self-motivation. The results provided evidence for the two pathways hypothesis of the effects of WTELS-F on EF. The conceptual and clinical implications of these findings were discussed.

    科学被认为是一个累积的过程(“站在巨人的肩膀上”),然而,科学知识通常是建立在没有太多协调的研究贡献的拼凑上。在临床研究中,针对生活系统评价和研究浪费的建议已特别解决了这种缺乏效率的问题。我们建议通过ALL-IN荟萃分析来进一步提出这些建议:AnytimeLive和LeadingINterim荟萃分析。ALL-IN为荟萃分析提供了统计方法,可以在每次新观察后随时更新-重新分析,同时保留I型错误保证,生活-不需要预先指定的外观,并主导决定是否应该开始个别研究,停止或展开,荟萃分析可能是主要的信息来源。我们说明了时间到事件数据的方法,显示当研究本身缓慢以提供完成所需的事件数量时,在研究的中期阶段合成数据如何提高效率。荟萃分析可以对临时数据进行,但不必。分析设计不需要有关试验中患者数量或最终纳入试验数量的信息。所以它可以为生活的系统评价注入活力,通过更好更简单的统计数据,效率,协作和沟通。
    Science is justly admired as a cumulative process (\"standing on the shoulders of giants\"), yet scientific knowledge is typically built on a patchwork of research contributions without much coordination. This lack of efficiency has specifically been addressed in clinical research by recommendations for living systematic reviews and against research waste. We propose to further those recommendations with ALL-IN meta-analysis: Anytime Live and Leading INterim meta-analysis. ALL-IN provides statistical methodology for a meta-analysis that can be updated at any time-reanalyzing after each new observation while retaining type-I error guarantees, live-no need to prespecify the looks, and leading-in the decisions on whether individual studies should be initiated, stopped or expanded, the meta-analysis can be the leading source of information. We illustrate the method for time-to-event data, showing how synthesizing data at interim stages of studies can increase efficiency when studies are slow in themselves to provide the necessary number of events for completion. The meta-analysis can be performed on interim data, but does not have to. The analysis design requires no information about the number of patients in trials or the number of trials eventually included. So it can breathe life into living systematic reviews, through better and simpler statistics, efficiency, collaboration and communication.

    目的:这项研究的目的是调查参加全国儿科泌尿外科会议的代表对现场病例演示(LCD)的意见,以了解将来是否可以用录音病例演示(TCD)代替这些意见。
    方法:在为期3天的年度会议和儿科泌尿外科现场手术研讨会结束时进行了问卷调查。除了一般数据,如受访者的年龄和执业类型,关于LCD的四个关键问题包括:如果没有LCD,您会参加这次会议吗?未经编辑的视频(TCD)与LCD一样有效地进行教学吗?您认为LCD应该继续进行吗?您会允许您的孩子由专家在LCD中进行手术吗?对于问题3,在初级外科医生(<45岁)和高级外科医生(>45岁)之间比较了结果。
    结果:关于分析,88/140(62%)受访者(95%置信区间[CI]:54%-70%)表示,如果没有LCD,他们将不会参加会议;70/139(50%)受访者(95%CI:42%-58%)认为TCD可能是LCD的有效替代品;129/144(90%)受访者(95%CI:83%-94%)认为应继续使用LCD。对于问题4,101/129(79%)表示他们将允许他们的孩子由专家在LCD中进行操作,而28人(21%)不同意他们的孩子在液晶显示器上手术。初级和高级外科医生对LCD的支持没有显着差异(P=0.15)。
    结论:在印度情况下,LCD被认为是儿科泌尿外科会议的重要组成部分,吸引更多参与,并且可能对会议的成功很重要。
    OBJECTIVE: The purpose of the study was to survey the opinion of delegates attending national pediatric urology meeting regarding live case demonstrations (LCDs) to see whether these can be replaced with taped case demonstrations (TCDs) in future.
    METHODS: A questionnaire-based survey was conducted at the end of the 3-day annual conference and live operative workshop in pediatric urology. Apart from general data such as age of the respondent and type of practice setting, four key questions on LCDs with yes/no responses included: would you have attended this meeting if there were no LCDs? Are unedited videos (TCDs) as effective as LCDs for teaching? Do you think LCDs should be continued? Would you allow your child to be operated in LCD by an expert? For question 3, the outcomes were compared between junior surgeons (<45-year-old) and senior surgeons (>45-year-old).
    RESULTS: On analysis, 88/140 (62%) respondents (95% confidence interval [CI]: 54%-70%) said that they would not have attended the meeting if there were no LCDs; 70/139 (50%) respondents (95% CI: 42%-58%) felt that TCDs may be an effective alternative to LCDs; 129/144 (90%) respondents (95% CI: 83%-94%) felt that LCDs should be continued. For question 4, 101/129 (79%) said they would allow their child to be operated in LCD by an expert, while 28 (21%) did not agree for their child to be operated in LCD. There was no significant difference between junior and senior surgeons regarding support for LCDs (P = 0.15).
    CONCLUSIONS: In the Indian scenario, LCDs were favored as an essential part of pediatric urology meeting, attract more participation, and are likely to be important for the success of the meeting.

    Less Invasive Ventricular Enhancement (LIVE) with Revivent TC is an innovative therapy for symptomatic ischemic heart failure (HF). It is designed to reconstruct a negatively remodeled left ventricle (LV) after an anterior myocardial infarction (MI) by plication of the scar tissue. Its indications are specific, and as with any other structural heart intervention, the success of the procedure starts with appropriate patient selection. We aim to present the indications of the technique, crucial aspects in patient selection, and individual case planning approach.
    After clinical evaluation, transthoracic echocardiography is the first imaging modality to be performed in a potential candidate for the therapy. However, definitive indication and detailed case planning rely on late gadolinium-enhanced cardiac magnetic resonance imaging or multiphasic contrast-enhanced cardiac computed tomography. These imaging modalities also assist with relative or absolute contra-indications for the procedure. Individual assessment is done to tailor the procedure to the specifics of the LV anatomy and location of the myocardial scar.
    LIVE procedure is a unique intervention to treat symptomatic HF and ischemic cardiomyopathy after anterior MI. It is a highly customizable intervention that allows a patient-tailored approach, based on multimodality imaging assessment and planification.

    由于冠状病毒大流行的社交距离要求,虚拟音乐会的受欢迎程度增加了。我们旨在研究虚拟音乐会的特征和参与者的特征如何影响他们的社交联系和kamamuta体验(通常被标记为“被感动”)。我们假设音乐会的活力和冠状病毒的显著性会影响社会关系和kamamuta。我们收集了来自4大洲13个国家的307名参与者的各种音乐会和个人特征的调查回复。我们将社会联系作为情感和行为的组合来操作,并且使用简短的kamamuta量表来测量kamamuta(Zickfeld等人。,2019)。我们发现(1)社会联系和kamamuta是相关的,并通过共情关注来预测,(2)现场音乐会产生了更多的社会联系,但不是kamamuta,比预先录制的音乐会,(3)音乐会期间冠状病毒的显著性预测kamamuta,这种影响完全由社会联系介导。探索性分析还检查了社会和身体存在的影响,出席音乐会的动机,和捐款的预测因素。这项研究有助于理解人们如何在虚拟环境中进行社交和情感联系。
    The popularity of virtual concerts increased as a result of the social distancing requirements of the coronavirus pandemic. We aimed to examine how the characteristics of virtual concerts and the characteristics of the participants influenced their experiences of social connection and kama muta (often labeled \"being moved\"). We hypothesized that concert liveness and the salience of the coronavirus would influence social connection and kama muta. We collected survey responses on a variety of concert and personal characteristics from 307 participants from 13 countries across 4 continents. We operationalized social connection as a combination of feelings and behaviors and kama muta was measured using the short kama muta scale (Zickfeld et al., 2019). We found that (1) social connection and kama muta were related and predicted by empathic concern, (2) live concerts produced more social connection, but not kama muta, than pre-recorded concerts, and (3) the salience of the coronavirus during concerts predicted kama muta and this effect was completely mediated by social connection. Exploratory analyses also examined the influence of social and physical presence, motivations for concert attendance, and predictors of donations. This research contributes to the understanding of how people can connect socially and emotionally in virtual environments.

    块状皮肤病,羊痘,山痘是牛的法定传染病,绵羊,和山羊,分别,由Capropoxvirus属病毒引起的。他们负责直接和间接的财务损失。这些损失是由动物死亡引起的,接种疫苗的发病率成本,以及对动物和动物产品贸易的限制。控制和根除病毒有赖于及早发现爆发,矢量控制,严格的动物运动,和疫苗接种仍然是最有效的控制手段。迄今为止,减毒活疫苗被广泛使用;然而,保护仍然存在争议。许多疫苗与绵羊的不良反应和不完全保护有关,山羊,和牛。还开发了许多基于组合和重组的疫苗。这里,我们回顾了针对每种反刍动物的羊痘病毒感染以及各自疫苗赋予的针对羊痘病毒的免疫力。我们还回顾了它们对异源感染的相关交叉保护。
    Lumpy skin disease, sheeppox, and goatpox are notifiable diseases of cattle, sheep, and goats, respectively, caused by viruses of the Capripoxvirus genus. They are responsible for both direct and indirect financial losses. These losses arise through animal mortality, morbidity cost of vaccinations, and constraints to animals and animal products\' trade. Control and eradication of capripoxviruses depend on early detection of outbreaks, vector control, strict animal movement, and vaccination which remains the most effective means of control. To date, live attenuated vaccines are widely used; however, conferred protection remains controversial. Many vaccines have been associated with adverse reactions and incomplete protection in sheep, goats, and cattle. Many combination- and recombinant-based vaccines have also been developed. Here, we review capripoxvirus infections and the immunity conferred against capripoxviruses by their respective vaccines for each ruminant species. We also review their related cross protection to heterologous infections.

    粗大运动发育测试(TGMD)是评估3至10岁儿童基本运动技能(FMS)的最常用工具之一。这项研究旨在通过实时和视频评估来检查专家和新手评估者之间TGMD-3版(TGMD-3)的评估者内部和评估者之间的可靠性。五名评估者[2名专家和3名新手(其中一名是体育和运动科学理学学士)]评估并评分了25名健康儿童的TGMD-3表现[女性:60%;平均(标准差)年龄9.16(1.31)]。学童在2019-2020学年期间从圣地亚哥德孔波斯特拉(西班牙)就读一所公立小学。评分者通过两种观看情绪(现场和慢动作)对每个孩子的表现进行评分。ICC(组内相关系数)用于确定评估者之间的一致性。我们的结果表明,总体得分以及运动和球技能子量表的评分者内部可靠性中等到出色;总体和球技能的评分者间可靠性中等到良好;以及运动子量表的差到好。与新手评估者相比,具有体育背景的专家评估者和新手评估者获得了更高的评估者内部可靠性。然而,无论评估者的经验或背景如何,评估者间的可靠性在所有评估者中都更具可变性。比较实时和视频评估时,没有发现可靠性的显着差异。对于临床实践,建议评估者在评估前达成协议,以避免可能扭曲结果的主观解释。
    The Test of Gross Motor Development (TGMD) is one of the most common tools for assessing the fundamental movement skills (FMS) in children between 3 and 10 years. This study aimed to examine the intra-rater and inter-rater reliability of the TGMD-3rd Edition (TGMD-3) between expert and novice raters using live and video assessment. Five raters [2 experts and 3 novices (one of them BSc in Physical Education and Sport Science)] assessed and scored the performance of the TGMD-3 of 25 healthy children [Female: 60%; mean (standard deviation) age 9.16 (1.31)]. Schoolchildren were attending at one public elementary school during the academic year 2019-2020 from Santiago de Compostela (Spain). Raters scored each children performance through two viewing moods (live and slow-motion). The ICC (Intraclass Correlation Coefficient) was used to determine the agreement between raters. Our results showed moderate-to-excellent intra-rater reliability for overall score and locomotor and ball skills subscales; moderate-to-good inter-rater reliability for overall and ball skills; and poor-to-good for locomotor subscale. Higher intra-rater reliability was achieved by the expert raters and novice rater with physical education background compared to novice raters. However, the inter-rater reliability was more variable in all the raters regardless of their experience or background. No significant differences in reliability were found when comparing live and video assessments. For clinical practice, it would be recommended that raters reach an agreement before the assessment to avoid subjective interpretations that might distort the results.

    Non-typhoidal Salmonella (NTS) is a major cause of gastroenteritis and is responsible for approximately 93 million cases annually. In healthy individuals, gastroenteritis caused by NTS is usually self-limiting, however, NTS can cause severe invasive disease in immunocompromised patients. Very little research has been directed towards development of vaccines against Salmonella serogroups O:6,7 or O:8. We have constructed a live attenuated serogroup O:8 vaccine, CVD 1979, by deleting guaBA, htrA, and aroA from the genome of S. Newport. We have shown that the candidate vaccine is well tolerated in mice and elicits serum immunoglobulin G (IgG) antibodies against core O-polysaccharide (COPS) when administered orally. Immunized mice were challenged intraperitoneally with wild-type S. Newport and bacterial burden in the liver and spleen was found to be significantly reduced in the livers of immunized mice compared to control mice. We also observed moderate vaccine efficacy (45%) against lethal challenge with the serogroup O:8 serovar, S. Muenchen, but low vaccine efficacy (28%) following lethal challenge with a serogroup O:6,7 serovar, S. Virchow. In vitro, we have shown that antibodies generated by CVD 1979 only recognize lipopolysaccharide (LPS) from serogroup O:8 but not serogroup O:6,7 serovars, and that they mediate opsonophagocytic antibody (OPA) activity against serogroup O:8 but not serogroup O:6,7 serovars. We also showed that OPA activity can be blocked by pre-incubating the antisera with serogroup O:8 lipopolysaccharide. Taken together, our data demonstrate that we have constructed a well-tolerated, effective live attenuated S. Newport vaccine which elicits functional antibodies against serogroup O:8 but not O:6,7 serovars.
