    OBJECTIVE: To investigate the feasibility of constructing the risk index of Echinococcus infection based on the classification of echinococcosis lesions, so as to provide insights into the management of echinococcosis.
    METHODS: The imaging data of echinococcosis cases were collected from epidemiological surveys of echinococcosis in China from 2012 to 2016, and the detection of incident echinococcosis cases was captured from the annual echinococcosis prevention and control reports across provinces (autonomous regions) and Xinjiang Production and Construction Corps in China from 2017 to 2022. After echinococcosis lesions were classified, a risk index of Echinococcus infection was constructed based on the principle of discrete distribution marginal probability and multi-group classification data tests. The correlation between the risk index of Echinococcus infection and the detection of incident echinococcosis cases was evaluated in the provinces (autonomous regions and corps) from 2017 to 2022, and the correlations between the short and medium-term risk indices and between the medium and long-term risk indices of Echinococcus infection were examined using a univariate linear regression model.
    RESULTS: A total of 4 014 echinococcosis cases in China from 2012 to 2016 were included in this study. The short-, medium- and long-term risk indices of E. granulosus infection varied in echinococcosis-endemic provinces (autonomous regions and corps) of China (χ2 = 4.12 to 708.65, all P values < 0.05), with high short- (0.058), medium- (0.137) and long-term risk indices (0.104) in Tibet Autonomous Region, and the short-, medium- and long-term risk indices of E. multilocularis infection varied in echinococcosis-endemic provinces (autonomous regions and corps) of China (χ2 = 6.74 to 122.60, all P values < 0.05), with a high short-term risk index in Sichuan Province (0.016) and high medium- (0.009) and long-term risk indices in Qinghai Province (0.018). There were no significant correlations between the risk index of E. granulosus infection and the detection of incident cystic echinococcosis cases during the study period (t = -0.518 to 2.265, all P values > 0.05), and strong correlations were found between the risk indices of E. multilocularis infection and the detection of incident alveolar echinococcosis cases (including mixed type) in 2018, 2020, 2021, 2022, during the period from 2017 through 2020, from 2017 through 2021, from 2017 through 2022 (all r values > 0.7, t = 2.521 to 3.692, all P values < 0.05). Linear regression models were established between the risk index of E. multilocular infection and the detection of alveolar echinococcosis cases (including mixed type), and the models were all statistically significant (b = 0.214 to 2.168, t = 2.458 to 3.692, F = 6.044 to 13.629, all P values < 0.05). The regression coefficients for the correlations between the medium- and short-term, and between the long- and medium-term risk indices of E. granulosus infection were 2.339 and 0.765, and the regression coefficients for the correlations between the medium- and short-term, and between the long- and medium-term risk indices of E. multilocular infection were 0.280 and 1.842, with statistical significance seen in both the regression coefficients and regression models (t = 16.479 to 197.304, F = 271.570 to 38 928.860, all P values < 0.05).
    CONCLUSIONS: The risk index of Echinococcus infection has been successfully established based on the classification of echinococcosis lesions, which may provide insights into the prevention and control, prediction, diagnosis and treatment, and classified management of echinococcosis.

    可扩展的PTSD筛查策略必须简短,准确,能够由非专业劳动力管理。
    我们使用由结构化临床访谈确定的PTSD作为我们的黄金标准,并考虑了(a)创伤后应激清单5(PCL-5)的预测因素集,(b)DSM-5(PC-PTSD)的初级保健PTSD屏幕,(c)PCL-5和PC-PTSD问题,以确定肯尼亚公共部门环境中PTSD筛查的最佳项目。通过最小化验证数据中的平均平方误差来拟合使用LASSO的逻辑回归模型。接收器工作特性曲线下面积(AUROC)测量辨别性能。
    惩罚回归分析提出了一种筛选工具,该工具将两个PCL-5问题的李克特量表值求和-对压力经历(#1)和失眠(#21)的侵入性想法。根据MINI的评估,预测PTSD的AUROC为0.85(使用固定测试数据),优于PC-PTSD。AUROC在按年龄定义的亚组中相似,性别,除了没有创伤史的患者,经历的创伤类别数量(所有AUROC>0.83)-AUROC为0.78。
    在某些东非环境中,2个项目的PTSD筛查工具可能优于更长的筛查人员,并且很容易由非专业人员进行缩放。
    UNASSIGNED: Scalable PTSD screening strategies must be brief, accurate and capable of administration by a non-specialized workforce.
    UNASSIGNED: We used PTSD as determined by the structured clinical interview as our gold standard and considered predictors sets of (a) Posttraumatic Stress Checklist-5 (PCL-5), (b) Primary Care PTSD Screen for the DSM-5 (PC-PTSD) and, (c) PCL-5 and PC-PTSD questions to identify the optimal items for PTSD screening for public sector settings in Kenya. A logistic regression model using LASSO was fit by minimizing the average squared error in the validation data. Area under the receiver operating characteristic curve (AUROC) measured discrimination performance.
    UNASSIGNED: Penalized regression analysis suggested a screening tool that sums the Likert scale values of two PCL-5 questions-intrusive thoughts of the stressful experience (#1) and insomnia (#21). This had an AUROC of 0.85 (using hold-out test data) for predicting PTSD as evaluated by the MINI, which outperformed the PC-PTSD. The AUROC was similar in subgroups defined by age, sex, and number of categories of trauma experienced (all AUROCs>0.83) except those with no trauma history- AUROC was 0.78.
    UNASSIGNED: In some East African settings, a 2-item PTSD screening tool may outperform longer screeners and is easily scaled by a non-specialist workforce.

    狼疮性肾炎患者会出现疾病症状和治疗副作用。尽管自我管理行为在这种疾病的患者中很重要,对影响这些行为的因素的研究有限。
    本研究旨在探讨狼疮性肾炎患者自我管理行为的影响因素。
    这项横断面研究是在2019年8月至2020年12月期间在泰国一家大学医院的240名狼疮性肾炎患者中进行的,采用随机抽样方法。使用人口统计学和临床特征问卷收集数据,自我管理行为问卷,管理慢性病的自我效能感:6项量表,狼疮性肾炎知识问卷,家庭支持量表,成人生活问卷中的社会网络,狼疮性肾炎纪念症状评定量表。采用描述性统计和多元线性回归分析。
    参与者报告了中等水平的自我管理行为。多元回归分析显示,疾病持续时间,收入,症状,自我效能感,知识,家庭支持,社交网络,狼疮性肾炎和类别显着解释了自我管理行为变化的21%(R2=0.21;F(8,231)=7.73;p<0.001)。家庭支持(β=0.32,p<0.001)和症状(β=-0.23,p<0.001)是狼疮性肾炎患者自我管理行为的重要决定因素。
    这些发现为护士更好地了解影响狼疮性肾炎患者自我管理行为的因素提供了有价值的见解。家庭支持低,症状严重程度高的患者可能难以执行自我管理行为。护士应更多关注这些患者,并提供基于家庭的干预措施,以优化该人群的自我管理行为。
    UNASSIGNED: Patients with lupus nephritis experience disease symptoms and side effects from treatment. Although self-management behaviors are important in patients with this disease, there is limited research on the factors influencing these behaviors.
    UNASSIGNED: This study aimed to examine the factors influencing self-management behaviors in patients with lupus nephritis.
    UNASSIGNED: This cross-sectional study was conducted in 240 patients with lupus nephritis at a university hospital in Thailand between August 2019 and December 2020 using a random sampling method. Data were collected using a demographic and clinical characteristic questionnaire, Self-Management Behavior Questionnaire, Self-efficacy for Managing Chronic Disease: A 6-item Scale, Knowledge about Lupus Nephritis Questionnaire, Family Support Scale, Social Networks in Adult Life Questionnaire, and Memorial Symptom Assessment Scale for Lupus Nephritis. Descriptive statistics and multiple linear regression analyses were employed.
    UNASSIGNED: The participants reported a moderate level of self-management behaviors. Multiple regression analyses revealed that disease duration, income, symptoms, self-efficacy, knowledge, family support, social networks, and classes of lupus nephritis significantly explained 21% of the variance in self-management behaviors (R2 = 0.21; F(8,231) = 7.73; p <0.001). Family support (β = 0.32, p <0.001) and symptoms (β = -0.23, p <0.001) were significant determinants of self-management behaviors in patients with lupus nephritis.
    UNASSIGNED: The findings provide valuable insight for nurses to better understand the factors influencing self-management behaviors in patients with lupus nephritis. Patients with low family support and high symptom severity may face difficulty in performing self-management behaviors. Nurses should pay more attention to these patients and provide family-based interventions to optimize self-management behaviors in this population.

    基因表达是动态的,并且在过程的不同阶段有所不同。鉴定具有时间特异性表达模式的基因谱可以为正在进行的生物过程提供有价值的见解。比如细胞周期,细胞发育,昼夜节律,或对外部刺激的反应,如药物治疗或病毒感染。然而,目前,没有数据库定义,识别或存档具有时间特异性表达模式的基因谱。这里,使用高通量回归分析方法,将8个线性和非线性参数模型拟合到来自时间序列实验的基因表达谱中,以鉴定具有时间特异性表达模式的8种类型的基因谱.我们整理了2684个时间序列转录组数据集,并鉴定了2644,370个表现出时间特异性表达模式的基因谱。结果存储在数据库GeTeSEPdb(具有时间特异性表达模式数据库的基因谱,http://www。inbirg.com/GeTeSEPdb/)。此外,我们实施了一个在线工具,从用户提交的数据中鉴定具有时间特异性表达模式的基因谱.总之,GeTeSEPdb是一个全面的网络服务,可用于识别和分析具有时间特异性表达模式的基因谱。这种方法有助于探索转录变化和反应的时间模式。我们坚信GeTeSEPdb将成为生物学家和生物信息学家的宝贵资源。
    Gene expression is dynamic and varies at different stages of processes. The identification of gene profiles with temporal-specific expression patterns can provide valuable insights into ongoing biological processes, such as the cell cycle, cell development, circadian rhythms, or responses to external stimuli such as drug treatments or viral infections. However, currently, no database defines, identifies or archives gene profiles with temporal-specific expression patterns. Here, using a high-throughput regression analysis approach, eight linear and nonlinear parametric models were fitted to gene expression profiles from time-series experiments to identify eight types of gene profiles with temporal-specific expression patterns. We curated 2684 time-series transcriptome datasets and identified 2644,370 gene profiles exhibiting temporal-specific expression patterns. The results were stored in the database GeTeSEPdb (gene profiles with temporal-specific expression patterns database, http://www.inbirg.com/GeTeSEPdb/). Moreover, we implemented an online tool to identify gene profiles with temporal-specific expression patterns from user-submitted data. In summary, GeTeSEPdb is a comprehensive web service that can be used to identify and analyse gene profiles with temporal-specific expression patterns. This approach facilitates the exploration of transcriptional changes and temporal patterns of responses. We firmly believe that GeTeSEPdb will become a valuable resource for biologists and bioinformaticians.

    使用最大似然估计(MLE)拟合的风险预测模型通常过度拟合,导致预测过于极端,校准斜率(CS)小于1。惩罚方法,比如里奇和套索,已经被建议作为这个问题的解决方案,因为它们倾向于将回归系数缩小到零,导致预测更接近平均值。收缩量由调谐参数调节,λ,$\\lambda,$通常通过交叉验证(“标准调整”)选择。尽管已经发现惩罚方法可以平均改善校准,它们经常过度收缩,并在选定的λ$\\lambda$和CS中表现出很大的可变性。这是个问题,特别是对于小样本量,而且在使用样本量时也建议控制过拟合。我们考虑这些问题是否部分是由于使用交叉验证选择λ$\\lambda$,与原始开发样本相比,“训练”数据集的大小减小,导致λ$\\lambda$的高估,因此,过度收缩。我们提出了一种改进的交叉验证调优方法(“改进的调优”),从通过从原始数据集引导获得的伪开发数据集估计λ$\\lambda$,尽管尺寸较大,这样得到的交叉验证训练数据集的大小与原始数据集相同。修改的调谐可以在标准软件中容易地实现,并且与调谐参数的引导选择(“引导调谐”)密切相关。我们使用推荐的样本量在模拟和真实数据中评估了Ridge和Lasso的修改和引导调整,和尺寸略低和高。他们大大改进了λ$\\lambda$的选择,与标准调谐方法相比,CS得到了改进。与MLE相比,他们还改进了预测。
    Risk prediction models fitted using maximum likelihood estimation (MLE) are often overfitted resulting in predictions that are too extreme and a calibration slope (CS) less than 1. Penalized methods, such as Ridge and Lasso, have been suggested as a solution to this problem as they tend to shrink regression coefficients toward zero, resulting in predictions closer to the average. The amount of shrinkage is regulated by a tuning parameter, λ , $\\lambda ,$ commonly selected via cross-validation (\"standard tuning\"). Though penalized methods have been found to improve calibration on average, they often over-shrink and exhibit large variability in the selected λ $\\lambda $ and hence the CS. This is a problem, particularly for small sample sizes, but also when using sample sizes recommended to control overfitting. We consider whether these problems are partly due to selecting λ $\\lambda $ using cross-validation with \"training\" datasets of reduced size compared to the original development sample, resulting in an over-estimation of λ $\\lambda $ and, hence, excessive shrinkage. We propose a modified cross-validation tuning method (\"modified tuning\"), which estimates λ $\\lambda $ from a pseudo-development dataset obtained via bootstrapping from the original dataset, albeit of larger size, such that the resulting cross-validation training datasets are of the same size as the original dataset. Modified tuning can be easily implemented in standard software and is closely related to bootstrap selection of the tuning parameter (\"bootstrap tuning\"). We evaluated modified and bootstrap tuning for Ridge and Lasso in simulated and real data using recommended sample sizes, and sizes slightly lower and higher. They substantially improved the selection of λ $\\lambda $ , resulting in improved CS compared to the standard tuning method. They also improved predictions compared to MLE.

    在0K至300K的温度范围内,可以通过Debye-Einstein积分以物理上合理的方式描述许多结晶固体的热容数据。德拜-爱因斯坦方法的参数可以通过马尔可夫链蒙特卡罗(MCMC)全局优化方法或通过Levenberg-Marquardt(LM)局部优化例程获得。在MCMC方法的情况下,同时优化模型参数和描述测量点残差的函数的系数。因此,得到热容函数的贝叶斯可信区间。尽管两种回归工具(LM和MCMC)是完全不同的方法,不仅仅是德拜-爱因斯坦参数的值,但它们的标准误差似乎也相似。然后使用计算的模型参数及其相关的标准误差来推导焓,熵和吉布斯能量作为温度的函数。通过直接插入所有4·105计算机的MCMC参数,可以运行积分焓的分布,熵和吉布斯能量被确定。
    Heat capacity data of many crystalline solids can be described in a physically sound manner by Debye-Einstein integrals in the temperature range from 0K to 300K. The parameters of the Debye-Einstein approach are either obtained by a Markov chain Monte Carlo (MCMC) global optimization method or by a Levenberg-Marquardt (LM) local optimization routine. In the case of the MCMC approach the model parameters and the coefficients of a function describing the residuals of the measurement points are simultaneously optimized. Thereby, the Bayesian credible interval for the heat capacity function is obtained. Although both regression tools (LM and MCMC) are completely different approaches, not only the values of the Debye-Einstein parameters, but also their standard errors appear to be similar. The calculated model parameters and their associated standard errors are then used to derive the enthalpy, entropy and Gibbs energy as functions of temperature. By direct insertion of the MCMC parameters of all 4·105 computer runs the distributions of the integral quantities enthalpy, entropy and Gibbs energy are determined.

    土壤有机碳(SOC)是决定土壤肥力和环境质量的关键。传统SOC化学分析方法的问题在于它们耗时且资源密集。近年来,可见近红外(Vis-NIR)光谱已被用作SOC测定的替代方法。然而,当应用于更大规模时,由于样品的异质性,土壤性质的预测精度降低。因此,本研究比较和分析了偏最小二乘回归(PLSR)的性能,支持向量回归(SVR),随机森林(RF),和高斯过程回归(GPR)在SOC预测中的应用。在此基础上,提出了一种基于混合核函数的GPR模型(HKF-GPR)用于SOC预测。该混合核函数是根据单个核函数的性质和土壤光谱数据的特点设计的。结果表明,在大型土壤光谱数据库中,探地雷达模型在估计SOC方面优于其他模型。HKF-GPR模型实现了最佳SOC估计精度,R2为0.7671,RMSE为5.2934g/kg,RPD为2.0721,RPIQ为2.5789。与其他回归模型相比,本文提出的HKF-GPR模型具有更广泛的适用性和优越的性能,在大型土壤光谱库中实现SOC估计。
    Soil Organic Carbon (SOC) is crucial for determining soil fertility and environmental quality. The problem with traditional SOC chemical analysis methods is that they are time-consuming and resource-intensive. In recent years, visible-near infrared (Vis-NIR) spectroscopy has been employed as an alternative method for SOC determination. However, when applied on a larger scale, the prediction accuracy of soil properties decreases due to the heterogeneity of samples. Therefore, this study compared and analyzed the performance of partial least squares regression (PLSR), support vector regression (SVR), random forest (RF), and gaussian process regression (GPR) in predicting SOC. On this basis, a GPR model based on a hybrid kernel function (HKF-GPR) was proposed for SOC prediction. This hybrid kernel function was designed according to the properties of single kernel functions and the characteristics of soil spectral data. Results indicate that in large soil spectral databases, the GPR model outperforms other models in estimating SOC. The HKF-GPR model achieved the best SOC estimation accuracy, with an R2 of 0.7671, RMSE of 5.2934 g/kg, RPD of 2.0721, and RPIQ of 2.5789. Compared to other regression models, the HKF-GPR model proposed in this paper offers broader applicability and superior performance, enabling SOC estimation in large soil spectral libraries.

    众所周知的连续分布,如Beta和Kumaraswamy分布对于基于单位间隔[0,1]的数据集建模是有用的。但是每个分布并不总是对所有类型的数据集有用,相反,它也取决于数据的形状。在这项研究中,定义了一个名为有界指数Weibull(BEW)分布的三参数新分布,以在单位区间[0,1]的支持下对数据集进行建模。已经研究了BEW分布的一些基本分布性质。对于数据集中度量之间的相关性建模,开发了BEW分布的双变量扩展,并显示了二元BEW分布的图形形状。已经讨论了几种估计方法来估计BEW分布的参数并检查估计器的性能,进行了蒙特卡罗模拟研究。之后,BEW分布的应用使用COVID-19数据集进行了说明。所提出的分布显示出比许多众所周知的分布更好的拟合。最后,建立了有界指数Weibull分布的分位数回归模型,并显示了概率密度函数(PDF)和危险函数的图形形状。
    Well-known continuous distributions such as Beta and Kumaraswamy distribution are useful for modeling the datasets which are based on unit interval [0,1]. But every distribution is not always useful for all types of data sets, rather it depends on the shapes of data as well. In this research, a three-parameter new distribution named bounded exponentiated Weibull (BEW) distribution is defined to model the data set with the support of unit interval [0,1]. Some fundamental distributional properties for the BEW distribution have been investigated. For modeling dependence between measures in a dataset, a bivariate extension of the BEW distribution is developed, and graphical shapes for the bivariate BEW distribution have been shown. Several estimation methods have been discussed to estimate the parameters of the BEW distribution and to check the performance of the estimator, a Monte Carlo simulation study has been done. Afterward, the applications of the BEW distribution are illustrated using COVID-19 data sets. The proposed distribution shows a better fit than many well-known distributions. Lastly, a quantile regression model from bounded exponentiated Weibull distribution is developed, and its graphical shapes for the probability density function (PDF) and hazard function have been shown.

There are many schools in Wuhan, with nearly a thousand of all kinds. The number of students is ~2.2 million, accounting for nearly one-fifth of the resident population; college or university students account for ~60% of the total student population. The geographical location of these colleges is relatively concentrated, and the population density is relatively high, making it prone to tuberculosis cluster epidemic.
    UNASSIGNED: This study analyzed the epidemiological characteristics and influencing factors of tuberculosis aggregation in schools in Wuhan, China, during 2017-2022 to provide the basis for the scientific development of tuberculosis prevention and control strategies and measures in schools.
    UNASSIGNED: This study adopted the methods of descriptive epidemiology to analyze the epidemic characteristics of tuberculosis aggregation in schools in Wuhan from January 2017 to December 2022, collecting the relevant data on tuberculosis prevention and control in all kinds of schools in the city using Questionnaire Star, an application of the China network questionnaire survey, and analyze the influencing factors of tuberculosis aggregation by using multifactor logistic regression analysis.
    UNASSIGNED: From 2017 to 2022, 54 outbreaks of pulmonary tuberculosis aggregation in schools were reported in Wuhan, which involved 37 different schools, including 32 colleges or universities and five senior high schools; 176 cases were reported, among which 73 were positive for pathogens and 18 were rifampicin or izoniazid resistant. The median duration of a single cluster epidemic was 46 (26,368) days. Universities were more prone to cluster outbreaks than middle schools (χ2 = 105.160, P = 0.001), and the incidence rate among male students was higher than that of female students in cluster epidemics (χ2 = 12.970, P = 0.001). The multivariate logistic regression analysis results showed that boarding in school (OR = 7.60) is the risk factor for a tuberculosis cluster epidemic in schools. The small number of students (OR = 0.50), the location of the school in the city (OR = 0.60), carry out physical examinations for freshmen (OR = 0.44), carry out illness absence and cause tracking (OR = 0.05), dormitories and classrooms are regularly ventilated with open windows (OR = 0.16), strict implement the management of sick student\'s suspension from school (OR = 0.36), and seeking timely medical consultation (OR = 0.32) were the protective factors for a tuberculosis cluster epidemic in schools.
    UNASSIGNED: We successfully identified the epidemiological characteristics and influencing factors of tuberculosis aggregation in schools in Wuhan. The results revealed the influence and status of various factors and indicated ways for schools to improve their TB prevention and control measures in their daily activities. These measures can effectively help curb the cluster epidemic of tuberculosis in schools.
