    Alder黄(ALY)植原体(16SrV-C)与ALY有关,欧洲的几种Alnus(al木)和北美的A.rubra的一种疾病。在所有受影响的物种中,症状相似。然而,潜伏感染很常见。ALY植物质包括不同的菌株,这些菌株可能偶尔传播给葡萄树,从而导致一些葡萄树黄色疾病。在目前的研究中,视觉症状评估和基于PCR的方法,使用通用和群体特异性的植原体引物,以更新和扩展知识的发生,影响,在意大利南部的Basilicata和Campania地区,下降且无症状的a.glutinosa和A.cordata树的ALY植物血浆的遗传多样性。在所检查的80%的al木中检测到ALY植物质。在有症状的树上,没有观察到其他疾病原因。超过一半的测试植物支原体阳性的al木被证明是潜在感染的。在意大利南部新记录的ALY植物质菌株中,几乎在所检查的基因中都观察到了相当大的遗传变异。这些包括16SrRNA,16S/23SrDNA间隔区,核糖体蛋白rpsV(rpl22)和rpsC(rps3),地图,imp,和GroEL基因。在图谱基因序列水平上鉴定出11种新的基因型。然而,观察到的遗传差异与植物宿主物种无关,地理起源,和受感染的秃木表现出的症状。此外,这项研究表明,ALY植原体比以前认为的更广泛。
    Alder yellows (ALY) phytoplasma (16SrV-C) is associated with ALY, a disease of several Alnus (alder) species in Europe and A. rubra in North America. In all affected species, the symptoms are similar. However, latent infections are common. ALY phytoplasma includes different strains which may be occasionally transmitted to grapevines leading to some grapevine yellows diseases. In the current study, visual symptom assessment and PCR-based methods using universal and group-specific phytoplasma primers were used to update and extend knowledge on the occurrence, impact, and genetic diversity of ALY phytoplasma in declining and non-symptomatic A. glutinosa and A. cordata trees in the Basilicata and Campania regions of southern Italy. ALY phytoplasma was detected in 80% of alder trees examined. In symptomatic trees, no other cause of disease was observed. More than half of alder trees that tested phytoplasma-positive proved to be latently infected. A considerable genetic variability was observed among the newly recorded ALY phytoplasma strains in southern Italy in almost of the genes examined. These included 16S rRNA, 16S/23S rDNA spacer region, ribosomal protein rpsV (rpl22) and rpsC (rps3), map, imp, and groEL genes. Eleven new genotypes were identified at map gene sequence level. However, the genetic differences observed were not related to plant host species, geographical origin, and symptoms shown by infected alder trees. Also, this study indicates that ALY phytoplasma is more widespread than previously thought.

    大学人口对视觉有很高的要求。因此,评估这些受试者的症状患病率很重要,这可能会影响他们的学习成绩。在这项横断面研究中,来自一所大学的252名受试者的随机样本回答了趋同不足症状调查(CISS)问卷。此外,在接近任务期间和之后,被问及关于视力模糊的问题,每天在近视力中花费的小时数,他们是否戴眼镜。此外,110名受试者接受了眼科检查,包括折射和调节评估。受试者的平均年龄为28.79±11.36岁,62.3%报告戴眼镜,平均7.20±2.92小时/天用于近视力。CISS评分的平均值为18.69±9.96,根据其标准,38%的受试者有症状。在戴眼镜的受试者中,一些症状明显更频繁(p<0.05)。30.9%的受试者存在调节功能障碍,最常见的是住宿不足。我们强调在这组受试者的临床检查期间评估症状学的重要性,因为他们每天在近视力中花费许多小时,以及评估住宿,双目视觉,和符合人体工程学的工作环境,这可能是症状的起源,另外需要戴眼镜。
    The university population has high visual demands. It is therefore important to assess the prevalence of symptoms in these subjects, which may affect their academic performance. In this cross-sectional study, a randomized sample of 252 subjects from a university answered the Convergence Insufficiency Symptom Survey (CISS) questionnaire. In addition, questions were asked about blurred vision during and after near tasks, the number of hours per day spent in near vision, and whether or not they wore glasses. Furthermore, 110 subjects underwent an eye exam, including a refraction and accommodation assessment. The mean age of the subjects was 28.79 ± 11.36 years, 62.3% reported wearing glasses, and on average 7.20 ± 2.92 hours/day was spent in near vision. The mean of the CISS score was 18.69 ± 9.96, and according to its criteria, 38% of the subjects were symptomatic. Some symptoms were significantly (p < 0.05) more frequent in subjects wearing glasses. Accommodative dysfunctions were present in 30.9% of the subjects, the most common being insufficiency of accommodation. We emphasise the importance of assessing symptomatology during the clinical examination in this group of subjects, as they spend many hours a day in near vision, as well as assessing accommodation, binocular vision, and the ergonomic work environment, which may be at the origin of the symptoms, in addition to the need to wear glasses.

    OBJECTIVE: To characterize the distribution of meibomian gland (MG) area loss (MGL) and its relationship with demographic characteristics, mites, and symptoms.
    METHODS: This retrospective observational study included patients who visited the Dry Eye Clinic of Shenzhen Eye Hospital between June 2020 and August 2021. General patient characteristics, ocular symptoms, Demodex test results of the eyelid edges, and the results of a comprehensive ocular surface analysis were collected. MGL was analyzed using Image J software.
    RESULTS: This study enrolled 1204 outpatients aged 20-80 (40.70±13.44)y, including 357 males (29.65%) and 847 females (70.35%). The patients were classified into mild (n=155; 12.87%), moderate (n=795; 66.03%), severe (n=206; 17.11%), and extremely severe (n=48; 3.99%) MGL groups. MGL was significantly larger in female than in male (P=0.006). The degree of MGL also significantly differed in age (P<0.001) and the more numbers of mites with severity (P<0.001). Multivariate disordered multinomial logistic regression analysis identified that female sex, older age, secretory symptoms, and a large number of mites were risk factors for MGL (P<0.05).
    CONCLUSIONS: Patients with MGL are more likely to be older, female, more numbers of mites, and increased secretion.

    目的:临床高危精神病(CHRp)样本可能是异质的,基本上由不仅有精神病样经历的人组成,而且有可能反映常见精神障碍如抑郁症的非特异性症状,焦虑,或药物滥用病理。很少有研究试图分析和了解与环境(ER)和心理病理风险(PsR)因素相关的精神病风险。这项研究旨在确定青少年精神病的临床风险。
    方法:使用不同的量表对来自普通人群的1824名西班牙青少年的代表性样本进行了评估,以彻底检查CHRp与各种ER和PsR因素的可能相互作用。计算偏相关以评估变量之间的关系。然后使用一系列分层线性回归模型来获得CHRp预测模型。
    结果:CHRp预测模型表明PsR是最重要的决定因素,解释了22%的CHRp总相关方差。然而,ER因子也是高危精神病的重要预测因子(占方差的9%).
    结论:发现了青少年CHRp的预测模型,与ER干扰物相比,常见的心理问题被认为是更决定性的危险因素。此外,某些诊断过程,比如心理上的僵化,可能在心理健康问题的发展中起着核心作用,包括精神病。明确CHRp在青春期出现的潜在机制是在这些早期阶段优化预防性治疗干预重点的关键。
    OBJECTIVE: Clinical high-risk of psychosis (CHRp) samples can be heterogeneous, consisting essentially of people with not only psychotic-like experiences but also nonspecific symptoms that may reflect common mental disorders such as depression, anxiety, or substance abuse pathologies. Few studies have attempted to analyze and understand psychosis risk in relation to both environmental (ER) and psychopathological risk (PsR) factors. This study aimed to determine the clinical risk of psychosis in adolescents.
    METHODS: A representative sample of 1824 Spanish adolescents from the general population was evaluated using different scales to thoroughly examine the possible interaction of CHRp with various ER and PsR factors. Partial correlations were calculated to assess the relationships between the variables. A series of hierarchical linear regression models were then used to obtain a CHRp predictor model.
    RESULTS: The CHRp predictor model indicated that PsR was the most significant determining factor, explaining 22% of the total associated variance of CHRp. However, the ER factor also emerged as a significant predictor of high-risk psychosis (accounting for 9% of the variance).
    CONCLUSIONS: A predictive model for CHRp in adolescents was found, in which common psychological problems were presented as more determinant risk factors than ER disruptors. Furthermore, certain transdiagnostic processes, such as psychological inflexibility, may play a central role in the development of mental health problems, including psychosis. Specifying the mechanisms underlying the emergence of CHRp in adolescence is the key to optimizing the focus of preventive therapeutic interventions in these early stages.

    背景:探讨当前抑郁发作的人口统计学和临床特征,将被诊断为重度抑郁障碍(MDD)的患者与被误诊为MDD的I型双相障碍(BP-I)和II型双相障碍(BP-II)患者区分开来。
    方法:进行微型国际神经精神病学访谈(MINI)评估以建立MDD的DSM-IV诊断,BP-I和BP-II,以前被误诊为MDD。人口统计,对1463例BP-I患者的抑郁症状和精神合并症进行了比较,中国大陆8个精神病患者的BP-II和MDD。进行多项逻辑回归模型以评估诊断的临床相关性。
    结果:总共14.5%的最初诊断为MDD的患者最终诊断为BP。广泛的疾病特征,包括年龄较小,复发率较高,并发心境恶劣,自杀企图,激动,精神病特征和精神病合并症,以及较低的失眠患病率,体重减轻和躯体症状表现为BP-I和/或BP-I患者,与MDD相比。BP-I和BP-II与MDD之间的比较表明不同的症状特征和合并症模式,BP-II和MDD之间观察到更多差异。而不是在BP-I和MDD之间。
    结论:结果提供了误诊的BP-I和BP-II与MDD之间的临床区别特征的证据。这些发现对于指导更准确的双相情感障碍诊断具有重要意义。
    BACKGROUND: To explore the demographic and clinical features of current depressive episode that discriminate patients diagnosed with major depressive disorder (MDD) from those with bipolar I (BP-I) and bipolar II (BP-II) disorder who were misdiagnosed as having MDD .
    METHODS: The Mini-International Neuropsychiatric Interview (MINI) assessment was performed to establish DSM-IV diagnoses of MDD, and BP-I and BP-II, previously being misdiagnosed as MDD. Demographics, depressive symptoms and psychiatric comorbidities were compared between 1463 patients with BP-I, BP-II and MDD from 8 psychiatric settings in mainland China. A multinomial logistic regression model was performed to assess clinical correlates of diagnoses.
    RESULTS: A total of 14.5% of the enrolled patients initially diagnosed with MDD were eventually diagnosed with BP. Broad illness characteristics including younger age, higher prevalence of recurrence, concurrent dysthymia, suicidal attempts, agitation, psychotic features and psychiatric comorbidities, as well as lower prevalence of insomnia, weight loss and somatic symptoms were featured by patients with BP-I and/or BP-I, compared to those with MDD. Comparisons between BP-I and BP-II versus MDD indicated distinct symptom profiles and comorbidity patterns with more differences being observed between BP-II and MDD, than between BP-I and MDD .
    CONCLUSIONS: The results provide evidence of clinically distinguishing characteristics between misdiagnosed BP-I and BP- II versus MDD. The findings have implications for guiding more accurate diagnoses of bipolar disorders.

    背景:弥漫性特发性骨骼骨肥厚症(DISH)是一种潜在的严重骨病,与前椎骨合并骨化相关,并可能伴有一系列症状学和全身性合并症。在全景射线照片和锥形束计算机断层扫描(CBCT)扫描中描述这一发现的牙科文献有限。
    方法:提供两例DISH病例报告。一名患者沿颈椎表现出广泛的骨化,并随后出现吞咽困难和声音嘶哑。另一名受影响的患者的宫颈骨化是在形成的早期阶段发现的,没有症状。全景摄影,颈椎X线照相术,已提供CBCT检查。
    结论:牙科保健医生在拍摄全景X线片和CBCT扫描时,应仔细评估所有感兴趣的区域和周围的视野,以了解DISH的表现和其他潜在的颈椎疾病。可疑的DISH放射学发现应及时转诊以进行全面的医学评估,以减轻神经功能缺损和其他合并症。
    BACKGROUND: Diffuse idiopathic skeletal hyperostosis (DISH) is a potentially serious osteopathic disorder associated with coalescing ossifications of the anterior vertebrae and may be concomitant with a constellation of symptomatology and systemic comorbidities. There is limited dental literature describing this finding on panoramic radiographs and cone beam computed tomography (CBCT) scans.
    METHODS: Two case reports of DISH are provided. One patient manifested extensive ossifications along the cervical vertebrae and consequent episodes of dysphagia and hoarseness. The other affected patient\'s cervical ossification was found at an earlier stage of formation and without symptomatology. Panoramic radiography, cervical spine radiography, and CBCT examinations have been provided.
    CONCLUSIONS: Attending dental healthcare practitioners should carefully evaluate all areas of interest and surrounding fields of view when taking panoramic radiographs and CBCT scans for manifestations of DISH and other potential disorders of the cervical vertebrae. A suspected radiologic finding of DISH should prompt timely referral for comprehensive medical assessment to mitigate neurologic deficits and other comorbidities.

    鉴于不同的症状表达和高合并症发生率,本研究探讨了受强迫症影响的儿童和青少年之间的潜在共性,以更好地概念化疾病表现和相关特征.汇总了830名受OCD影响的参与者到OCD专业中心的数据。依赖混合模型用于根据年龄和性别调整的症状严重程度(通过儿童耶鲁-布朗强迫症量表;CY-BOCS测量)检查潜在集群,症状类型(由CY-BOCS症状检查表计算的因子得分衡量),和共病诊断(通过诊断性访谈评估)。适合的统计数据有利于四簇模型,其群体主要通过症状表达和合并症类型来区分。3-7个集群模型的拟合指数仅略有不同,并且在更复杂的模型中添加了不同呈现的小集群的解决方案之间,集群的特征在很大程度上保持稳定。而不是确定一个单一的分类系统,这些发现支持整合维度的效用,发展,以及在受强迫症影响的儿童和青少年概念化中的诊断信息。已识别的群集指向强迫症的污染问题的中心地位,更广泛的症状表达和更高水平的共病之间的关系,以及复杂/神经发育表现的潜力。
    Given diverse symptom expression and high rates of comorbid conditions, the present study explored underlying commonalities among OCD-affected children and adolescents to better conceptualize disorder presentation and associated features. Data from 830 OCD-affected participants presenting to OCD specialty centers was aggregated. Dependent mixture modeling was used to examine latent clusters based on their age- and gender adjusted symptom severity (as measured by the Children\'s Yale-Brown Obsessive-Compulsive Scale; CY-BOCS), symptom type (as measured by factor scores calculated from the CY-BOCS symptom checklist), and comorbid diagnoses (as assessed via diagnostic interviews). Fit statistics favored a four-cluster model with groups distinguished primarily by symptom expression and comorbidity type. Fit indices for 3-7 cluster models were only marginally different and characteristics of the clusters remained largely stable between solutions with small clusters of distinct presentations added in more complex models. Rather than identifying a single classification system, the findings support the utility of integrating dimensional, developmental, and transdiagnostic information in the conceptualization of OCD-affected children and adolescents. Identified clusters point to the centrality of contamination concerns to OCD, relationships between broader symptom expression and higher levels of comorbidity, and the potential for complex/neurodevelopmental presentations.

    由于疾病产生的症状,长型COVID患者的生活质量下降。了解COVID对男性和女性的影响时间也很重要。这项研究的目的是从性别角度研究长期COVID症状对西班牙成年人生活质量的影响。
    进行了观察性和横断面研究。参与者能够使用在线平台完成在线问卷。206人参与了这项研究。
    80.6%的样本是平均年龄为46.51(±8.28)的女性,19.4%的样本是平均年龄为48.03(±9.50)的男性。PAC19-QoL测试的中分数为141.47(±24.96),并按性别进行分段,女性为141.65(±23.95),男性为140.82(±28.66)。女性最常见的症状是肌肉和关节痛(94.6%),疲劳(94.0%),不适(92.2%),难以集中注意力(91.0%),和记忆丧失(88.6%)。对于男性,症状包括肌肉和关节痛(97.5%)和疲劳(97.5%),两者都占据第一位置,不适(92.0%),难以集中注意力(90.0%),情绪障碍(90.0%),和记忆丧失(87.5%)。卡方检验显示社会人口统计信息有统计学意义(p<0.005),生活质量分数,和长期COVID症状的强度。
    这项研究表明,经历长期COVID的方式存在性别差异。
    Long COVID patients experience a decrease in their quality of life due to the symptomatology produced by the disease. It is also important to understand how long COVID affects both men and women. The objective of this study is to examine the impact of long COVID symptomatology on the quality of life of Spanish adults from a gender perspective.
    An observational and cross-sectional study was carried out. Participants were able to complete an online questionnaire using an online platform. A sample of 206 people participated in the study.
    The 80.6% of the sample were women with a mean age of 46.51 (±8.28) and the 19.4% were men with a mean age of 48.03 (±9.50). The medium score in the PAC19-QoL test was 141.47 (±24.96) and segmented by gender, 141.65 (±23.95) for women and 140.82 (±28.66) for men. The most common symptoms in women were muscle and joint pain (94.6%), fatigue (94.0%), discomfort (92.2%), difficulty concentrating (91.0%), and memory loss (88.6%). For men the symptoms included muscle and joint pain (97.5%) and fatigue (97.5%) both occupying first position, discomfort (92.0%), difficulty concentrating (90.0%), mood disturbances (90.0%), and memory loss (87.5%). The chi-square test showed statistical significance (p < 0.005) for socio-demographic information, quality of life scores, and long COVID symptoms by intensities.
    This study shows that there are gender differences in the way that long COVID is experienced.

    Understanding the symptoms of a mental disorder is essential for accurate diagnosis or selecting appropriate treatment targets. Despite this, there is a surprising lack of systematic research on the symptoms of selective mutism (SM). While the DSM-5 defines failure to speak as the only core symptom of SM, sparse research suggests that children with SM may experience additional symptoms. Previous studies have been limited in their identification of symptoms of SM, either by using a predefined set of symptoms or by only asking for anxiety-specific symptoms. This may have resulted in important symptoms being overlooked. In this study, we provided n = 86 parents of children and adolescents with SM (3-18 years) with a symptom definition appropriate for the target group. Additionally, parents were asked an open-ended question about any other symptoms they had observed in their children, beyond the failure to speak. The symptoms reported were categorized using qualitative content analysis (QCA) and examined for frequency and association with symptom severity. Ten different symptom categories were identified, with fear, freezing, and avoidance/security behaviors being the most prevalent. On average, parents reported M = 4.74 (SD = 2.37) symptoms from different symptom categories. Only fear was found to be related to symptom severity of SM. As the findings suggest that SM encompasses various symptoms beyond failure to speak, a more sophisticated understanding of SM as a mental disorder with multiple symptoms seems essential. The clinical implications of this are discussed in further detail.
