    我们已经彻底参与了题为“卡塔尔中风的流行病学概况:一项为期七年的观察研究的见解”的文章。作者在这一重要主题上的努力得到了极大的赞赏[1],这是值得读者认可的。我们由衷地感谢作者在这一重要课题上的持续努力,这是值得肯定的。文章的主要结论是中风的发病率正在增加。然而,与西方国家观察到的上升趋势相比,它仍然相对较低。我们同意这一评估。它强调了与中风相关的多种族人口和卡塔尔和外籍人口的独特危险因素。改善的紧急医疗服务和医疗保健服务有助于改善中风护理,强调了对所有人群进行指定中风护理策略和均衡护理的必要性。基于此,有一些额外的因素可能有助于文章的结论。
    We have thoroughly engaged with the article titled \"Epidemiological profile of stroke in Qatar: Insights from a seven-year observational study\". The author\'s diligent efforts regarding this critical subject matter are greatly appreciated [1], which is worthy of reader acknowledgment. We sincerely appreciate the author\'s ongoing efforts on this vital subject, which deserve recognition. The primary conclusion of the article is that the incidence of stroke is increasing. However, it remains relatively low compared to the rising trend observed in Western countries. We agree with this assessment. It highlights the multi-ethnic population and unique risk factors of the Qatari and expatriate populations that are associated with stroke. The necessity of investing in designated stroke care strategies and balanced care for all population groups is underscored by the improved emergency medical services and healthcare access that have contributed to improving stroke care. Based on this, there are a few additional elements that could have contributed to the article\'s conclusion.

    儿童肥胖是一个紧迫的全球公共卫生问题,因为它的广泛流行及其与早期生活暴露于危险因素的密切联系。肥胖的发生取决于遗传组成的相互作用,生活方式的选择,以及在胎儿发育和儿童早期遇到的环境和营养元素。本文严格审查了该领域的研究发现,并简要概述了母乳喂养对与儿童肥胖相关的遗传易感性的影响。研究表明,母乳喂养有可能通过影响人体测量指标来减少儿童肥胖。此外,母乳喂养的持续时间与其改变儿童肥胖风险的程度直接相关。目前对通过母乳传播的遗传因素与儿童肥胖之间联系的探索主要集中在FTO等基因上,瘦素,RXRα,PPAR-γ,和其他人。许多研究表明,长时间的纯母乳喂养与儿童肥胖的可能性降低有关。特别是在最初的六个月内持续。母乳喂养的持续时间也与基因甲基化相关。这可能是支撑母乳喂养预防肥胖的表观遗传机制。总之,这篇综述中提出的全面评估强调了母乳喂养之间联系的复杂性,遗传因素,和儿童肥胖,为未来的研究工作和政策制定提供有价值的见解。
    Childhood obesity represents a pressing global public health concern due to its widespread prevalence and its close connection to early-life exposure to risk factors. The onset of obesity is contingent upon the interplay of genetic composition, lifestyle choices, and environmental as well as nutritional elements encountered during both fetal development and early childhood. This paper critically examines research discoveries in this area and concisely outlines the influence of breastfeeding on genetic predispositions associated with childhood obesity. Studies have demonstrated that breastfeeding has the potential to reduce childhood obesity by impacting anthropometric indicators. Moreover, the duration of breastfeeding is directly correlated with the degree to which it alters the risk of childhood obesity. Current explorations into the link between genetic factors transmitted through breast milk and childhood obesity predominantly focus on genes like FTO, Leptin, RXRα, PPAR-γ, and others. Numerous research endeavors have suggested that an extended period of exclusive breastfeeding is tied to a diminished likelihood of childhood obesity, particularly if sustained during the initial six months. The duration of breastfeeding also correlates with gene methylation, which could serve as the epigenetic mechanism underpinning breastfeeding\'s preventative influence against obesity. In summary, the thorough evaluation presented in this review underscores the intricate nature of the association between breastfeeding, genetic factors, and childhood obesity, providing valuable insights for future research efforts and policy formulation.

    In thrombotic diseases, coagulation, anticoagulation, and fibrinolysis are three key physiological processes that interact to maintain blood in an appropriate state within blood vessels. When these processes become imbalanced, such as excessive coagulation or reduced anticoagulant function, it can lead to the formation of blood clots. Genetic factors play a significant role in the onset of thrombotic diseases and exhibit regional and ethnic variations. The decision of whether to initiate prophylactic anticoagulant therapy is a matter that clinicians must carefully consider, leading to the development of various thrombotic risk assessment scales in clinical practice. Given the considerable heterogeneity in clinical diagnosis and treatment, researchers are exploring the application of artificial intelligence in medicine, including disease prediction, diagnosis, treatment, prevention, and patient management. This paper reviews the research progress on various genetic factors involved in thrombotic diseases, analyzes the advantages and disadvantages of commonly used thrombotic risk assessment scales and the characteristics of ideal scoring scales, and explores the application of artificial intelligence in the medical field, along with its future prospects.

    目前,对不同人群中帕金森病(PD)致病变异的频谱和频率的估计是有限和有偏见的。此外,尽管几种遗传靶标的治疗修饰已经达到临床试验阶段,进行这些试验的一个主要障碍是PD患者基本上不知道他们的遗传状态,因此,不能招募。扩大研究的PD相关基因的数量,包括与临床特征重叠的疾病相关的基因,具有良好表型的PD患者组是捕获PD基础的全部变异谱以及对患者进行基因靶向临床试验的分层和优先排序的先决条件.罗斯托克帕金森氏病(ROPAD)研究是一项观察性临床研究,旨在确定大型国际队列中导致PD的遗传变异的频率和频谱。我们调查了来自16个国家的12580名PD患者的50个基因中的变异,这些基因与PD相关或可能的表型重叠[62.3%为男性;92.0%为白色;27.0%为阳性家族史(FH),使用下一代测序组的中位发病年龄(AAO)59岁]。总之,1864(14.8%)ROPAD参与者(58.1%男性;91.0%白人,35.5%FH+,AAO中位数55年),根据GBA1风险变异(10.4%)或LRRK2的致病/可能致病变异(2.9%),PD相关基因检测(PDGT)呈阳性,PRKN(0.9%),SNCA(0.2%)或PINK1(0.1%)或两个基因中两个遗传发现的组合(〜0.2%)。值得注意的是,调整后的正PDGT分数,即每个国家/地区的积极PDGT的比例,以它们所代表的世界人口的比例加权,为14.5%。在AAO≤50岁的患者中,有19.9%的PDGTs阳性,19.5%的FH+患者和26.9%的AAO≤50岁和FH+患者。与特发性PD组(6846例良性变异患者)相比,PDGT阳性组的AAO显着降低(4年,P=9×10-34)。每增加AAO年,PDGT阳性的概率降低3%(P=1×10-35)。女性患者PDGT阳性的可能性高22%(P=3×10-4),对于FH+的个体,这种可能性高出55%(P=1×10-14)。大约0.8%的ROPAD参与者在帕金森病中的基因检测结果为阳性-,肌张力障碍/运动障碍或痴呆相关基因。在基因靶向PD临床试验的新兴时代,我们的发现,约15%的患者携带潜在可操作的遗传变异,为受影响的个体及其家庭提供了重要的前景,并强调了对PD患者进行基因检测的必要性.因此,ROPAD研究的见解允许数据驱动,不同AAOs和家族史的差异遗传咨询,并促进可能的政策变化,将基因检测作为PD患者评估和护理的常规部分。
    Estimates of the spectrum and frequency of pathogenic variants in Parkinson\'s disease (PD) in different populations are currently limited and biased. Furthermore, although therapeutic modification of several genetic targets has reached the clinical trial stage, a major obstacle in conducting these trials is that PD patients are largely unaware of their genetic status and, therefore, cannot be recruited. Expanding the number of investigated PD-related genes and including genes related to disorders with overlapping clinical features in large, well-phenotyped PD patient groups is a prerequisite for capturing the full variant spectrum underlying PD and for stratifying and prioritizing patients for gene-targeted clinical trials. The Rostock Parkinson\'s disease (ROPAD) study is an observational clinical study aiming to determine the frequency and spectrum of genetic variants contributing to PD in a large international cohort. We investigated variants in 50 genes with either an established relevance for PD or possible phenotypic overlap in a group of 12 580 PD patients from 16 countries [62.3% male; 92.0% White; 27.0% positive family history (FH+), median age at onset (AAO) 59 years] using a next-generation sequencing panel. Altogether, in 1864 (14.8%) ROPAD participants (58.1% male; 91.0% White, 35.5% FH+, median AAO 55 years), a PD-relevant genetic test (PDGT) was positive based on GBA1 risk variants (10.4%) or pathogenic/likely pathogenic variants in LRRK2 (2.9%), PRKN (0.9%), SNCA (0.2%) or PINK1 (0.1%) or a combination of two genetic findings in two genes (∼0.2%). Of note, the adjusted positive PDGT fraction, i.e. the fraction of positive PDGTs per country weighted by the fraction of the population of the world that they represent, was 14.5%. Positive PDGTs were identified in 19.9% of patients with an AAO ≤ 50 years, in 19.5% of patients with FH+ and in 26.9% with an AAO ≤ 50 years and FH+. In comparison to the idiopathic PD group (6846 patients with benign variants), the positive PDGT group had a significantly lower AAO (4 years, P = 9 × 10-34). The probability of a positive PDGT decreased by 3% with every additional AAO year (P = 1 × 10-35). Female patients were 22% more likely to have a positive PDGT (P = 3 × 10-4), and for individuals with FH+ this likelihood was 55% higher (P = 1 × 10-14). About 0.8% of the ROPAD participants had positive genetic testing findings in parkinsonism-, dystonia/dyskinesia- or dementia-related genes. In the emerging era of gene-targeted PD clinical trials, our finding that ∼15% of patients harbour potentially actionable genetic variants offers an important prospect to affected individuals and their families and underlines the need for genetic testing in PD patients. Thus, the insights from the ROPAD study allow for data-driven, differential genetic counselling across the spectrum of different AAOs and family histories and promote a possible policy change in the application of genetic testing as a routine part of patient evaluation and care in PD.

    有人提出了COVID-19大流行对头颈癌(HNC)的影响,但因果关系尚不清楚。
    我们利用孟德尔随机化(MR)方法探索了这种联系,该方法应用于COVID-19和HNC的公开全基因组关联研究(GWAS)摘要数据集。数据集包括关键的COVID-19(13,769例,1,072,442个控件),住院COVID-19(32,519例,2,062,805个控件),SARS-CoV-2感染(122,616例,2,475,240个控件),和HNC(2,131例,287,137个控件)。通过基于AI的文献数据挖掘增强的功能注释,探索了通过MR分析确定的因果关系的机理基础。
    令人惊讶的是,感染较温和形式的COVID-19的遗传易感性大大降低了发展为HNC的风险(OR:0.52,95%CI:0.35-0.78,p=1.42E-03),严重COVID-19的遗传倾向与检测到的HNC风险之间没有显着关联。此外,我们的发现强调了与SARS-CoV-2感染相关的14个基因,在HNC的背景下可能发挥保护作用。这些基因包括OAS1,LOC107985887,BCL11A,DPP9,LOC107984685,LINC02326,MUC4,NXPE3,IFNAR2,LZTFL1,LOC105372437,NAPSA,LOC105376622、LOC107986082和SLC6A20。
    我们的研究强调了温和COVID-19的遗传倾向在降低HNC风险方面的保护作用,同时驳斥了严重COVID-19与HNC之间的因果关系。
    UNASSIGNED: The impact of the COVID-19 pandemic on head and neck cancer (HNC) has been suggested, but the causal relationship remains unclear.
    UNASSIGNED: We explore this connection by utilizing the Mendelian randomization (MR) approach applied to publicly available genome-wide association study (GWAS) summary datasets for COVID-19 and HNC. The datasets included critical COVID-19 (13,769 cases, 1,072,442 controls), hospitalized COVID-19 (32,519 cases, 2,062,805 controls), SARS-CoV-2 infection (122,616 cases, 2,475,240 controls), and HNC (2,131 cases, 287,137 controls). Mechanistic underpinnings of the causal relationships identified by MR analysis were explored through functional annotation augmented by AI-based literature data mining.
    UNASSIGNED: Surprisingly, a genetic predisposition to contracting a milder form of COVID-19 substantially reduced the risks of developing HNC (OR: 0.52, 95% CI: 0.35-0.78, p = 1.42E-03), with no significant association between genetic liability to severe COVID-19 and the risk of HNC detected. Additionally, our findings highlighted 14 genes linked to SARS-CoV-2 infection, potentially playing a protective role in the context of HNC. These genes include OAS1, LOC107985887, BCL11A, DPP9, LOC107984685, LINC02326, MUC4, NXPE3, IFNAR2, LZTFL1, LOC105372437, NAPSA, LOC105376622, LOC107986082, and SLC6A20.
    UNASSIGNED: Our study emphasizes the protective role of the genetic liability to milder COVID-19 in reducing the risk of HNC while refuting a causal relationship between severe COVID-19 and HNC.

    这项研究的目的是基于非遗传和遗传因素开发女孩早期青春期发育(EPD)的组合预测模型。
    病例对照研究包括147名被诊断患有EPD的女孩和256名表现出正常青春期发育的女孩。非遗传风险评分(NGRS)基于多变量logistic回归筛选的6个独立生化预测因子,使用28个EPD相关的单核苷酸多态性(SNP)构建遗传风险评分(GRS)。接收机操作特性曲线下面积(AROC),采用净重分类优化指数(NRI)和整合分化指数(IDI)评价在非遗传风险模型中添加遗传变异的改进效果。
    超重(OR=2.74),较长的电子屏幕时间(OR=1.79)和较高的塑料瓶装水比例(OR=1.01)是潜在的危险因素,运动时间长(OR=0.51)和白天睡眠时间长(OR=0.97)是EPD的保护因素,NGRS模型的AROC为83.6%(79.3-87.9%)。GRS与EPD有显著相关性(OR=1.90),GRS模型的AROC为65.3%(59.7-70.8%)。将GRS添加到NGRS模型后,AROC显着增加到85.7%(81.7-89.6%)(P=0.020),重新分类显著改善,NRI为8.19%(P=0.023),IDI为4.22%(P<0.001)。
    我们建立了女孩EPD的组合预测模型。将遗传变异添加到非遗传风险模型中带来了适度的改进。然而,超重和生活习惯等非遗传因素具有较高的预测效用。
    UNASSIGNED: The objective of this study is to develop a combined predictive model for early pubertal development (EPD) in girls based on both non-genetic and genetic factors.
    UNASSIGNED: The case-control study encompassed 147 girls diagnosed with EPD and 256 girls who exhibited normal pubertal development. The non-genetic risk score (NGRS) was calculated based on 6 independent biochemical predictors screened by multivariate logistic regressions, and the genetic risk score (GRS) was constructed using 28 EPD related single-nucleotide polymorphisms (SNPs). Area under receiver operator characteristic curve (AROC), net reclassification optimization index (NRI) and integration differentiation index (IDI) were used to evaluate the improvement of adding genetic variants to the non-genetic risk model.
    UNASSIGNED: Overweight (OR=2.74), longer electronic screen time (OR=1.79) and higher ratio of plastic bottled water (OR=1.01) were potential risk factors, and longer exercise time (OR=0.51) and longer day sleeping time (OR=0.97) were protective factors for EPD, and the AROC of NGRS model was 83.6% (79.3-87.9%). The GRS showed a significant association with EPD (OR=1.90), and the AROC of GRS model was 65.3% (59.7-70.8%). After adding GRS to the NGRS model, the AROC significantly increased to 85.7% (81.7-89.6%) (P=0.020), and the reclassification significantly improved, with NRI of 8.19% (P= 0.023) and IDI of 4.22% (P <0.001).
    UNASSIGNED: We established a combined prediction model of EPD in girls. Adding genetic variants to the non-genetic risk model brought modest improvement. However, the non-genetic factors such as overweight and living habits have higher predictive utility.

    心脏发育的传统描述涉及从心脏新月到线性心脏管的进展,在转化为成熟心脏的阶段,它形成了一个心脏回路,并与隔膜一起分为单个腔。心脏形态发生涉及许多类型的细胞起源于最初的心脏新月,包括神经嵴细胞,第二心脏区域起源的细胞,和心外膜祖细胞。胎儿心脏和循环系统的发育受遗传和环境过程的调节。先天性心脏病(CHD)的病因尚不清楚,但是一些遗传异常,一些产妇疾病,产前暴露于特定治疗和非治疗药物通常被认为是危险因素。研究心脏发育的新技术揭示了心脏形态发生的许多方面,这些方面在CHD的发展中很重要,特别是大动脉移位。
    The traditional description of cardiac development involves progression from a cardiac crescent to a linear heart tube, which in the phase of transformation into a mature heart forms a cardiac loop and is divided with the septa into individual cavities. Cardiac morphogenesis involves numerous types of cells originating outside the initial cardiac crescent, including neural crest cells, cells of the second heart field origin, and epicardial progenitor cells. The development of the fetal heart and circulatory system is subject to regulatation by both genetic and environmental processes. The etiology for cases with congenital heart defects (CHDs) is largely unknown, but several genetic anomalies, some maternal illnesses, and prenatal exposures to specific therapeutic and non-therapeutic drugs are generally accepted as risk factors. New techniques for studying heart development have revealed many aspects of cardiac morphogenesis that are important in the development of CHDs, in particular transposition of the great arteries.

    Mithun(Bosfrontalis),一个国内饲养的食草动物,对印度东北部的农业社区具有重要的经济意义。这项研究旨在使用来自印度唯一有组织的半密集型Mithun农场的数据,阐明控制不同年龄Mithun体重特征的遗传参数。信息是从2011年至2022年出生的110名Mithuns收集的。第1周的体重(W1),1个月(M1),3个月(M3),6个月(M6),9个月(M9),12个月(M12),研究考虑30个月(M30)和45个月(M45)。遗传参数估计采用BLUPF90程序套件,纳入具有固定效应的单变量吉布斯采样器动物模型;出生季节和时期,和动物的性别。方差和协方差分量,包括直接加性遗传效应,估计。八个体重性状的遗传力估计范围为0.47±0.0050至0.50±0.0043,表明整个生长阶段的遗传影响不同。结果表明,Mithun牧群的生长性状具有相当大的遗传变异性,因此有足够的余地选择更好的生长速率。这里,我们得出结论,第12个月(M12)和第9个月(M9)体重表现出更高的遗传力,表明通过选择性育种进行遗传改良的潜力。
    Mithun (Bos frontalis), a domestically raised herbivore, holds significant economic importance for the farming community of Northeast India. This study aimed to elucidate the genetic parameters governing Mithun body weight traits across different ages using data from the sole organized semi-intensive Mithun farm in India. Information was gathered from 110 Mithuns born over a period spanning from 2011 to 2022. Body weight taken at week 1 (W1), 1-month (M1), 3-months (M3), 6-months (M6), 9-months (M9), 12-months (M12), 30-months (M30) and 45-months (M45) were considered for the study. The genetic parameters estimation employed the BLUPF90 suite of programs, incorporating univariate Gibbs sampler animal model with fixed effects; season and period of birth, and sex of the animal. Variance and covariance components, including direct additive genetic effects, were estimated. Heritability estimates for the eight body weight traits ranged from 0.47 ± 0.0050 to 0.50 ± 0.0043, indicating varying genetic influence across growth stages. Results revealed that Mithun herd has a substantial genetic variability for growth traits and therefore there is ample scope to select for a better growth rate. Here, we conclude that Month 12 (M12) and Month 9 (M9) body weights exhibit higher heritability, indicating potential for genetic improvement through selective breeding.
