    由于大多数医学期刊的投稿率>80%,对于在提交之前寄予厚望的作者来说,这确实是一种震惊和悲伤。尽管大多数可用的文献都提到了如何在考虑重新提交给另一本期刊之前克服手稿中的空白,没有解决作者面临的精神痛苦和挫折以及克服这种挫折的方法。每个作者都应该培养免疫力,并有足够的心理准备来克服这种痛苦。
    With the majority of medical journals having a rejection rate of >80% of submitted manuscripts, it does come as a shock and as grief to the author who great expectations before submission. Though the majority of literature available does mention how to overcome the lacunae in the manuscript before considering resubmission in another journal, none addresses the mental agony and setback the author faces and the way to overcome this setback. Every author should develop immunity and also be adequately mentally prepared to overcome this misery.

    背景:南亚同性恋,双性恋,和其他与男性发生性关系的男性(GBM)在美国一直被忽视的艾滋病毒研究和规划。为了解决这个限制,本文介绍了他们的艾滋病相关知识,风险感知,和少数族裔的压力,重点是确定美国出生的个人和移民之间的差异。
    方法:从2022年4月至7月通过社交媒体广告和同伴转诊招募参与者,并对他们的社会人口统计学和HIV相关行为特征进行调查。先前验证的量表用于评估其与HIV相关的知识,风险感知,披露性身份,经历过同性恋恐惧症,以及在性和性别少数群体社区中感知到的种族主义。进行了Mann-Whitney-Wilcoxon测试,以比较在美国出生的人和在国外出生的人。
    结果:在112名参与者中,26人(23.21%)是美国出生的人,86人(76.79%)是移民。尽管性危险行为水平相似,比如有多个男性性伴侣,从事无公寓肛交,在性交之前或期间使用酒精或药物,与美国出生的人相比,移民的HIV相关知识水平较低(p=.0480)和风险感知水平较低(p=.0114)。移民也不太可能向家人透露自己的性身份,朋友,和社会与美国出生的个体相比(p=.0004)。在同性恋恐惧症的经历(p=.2303)或对种族主义的看法(p=.4011)方面没有发现差异。
    结论:需要针对美国南亚GBM的社会和文化规范进行全面的HIV预防工作。
    BACKGROUND: South Asian gay, bisexual, and other men who have sex with men (GBM) in the United States have been persistently overlooked in HIV research and programming. To address this limitation, this article describes their HIV-related knowledge, risk perception, and minority stressors, with a focus on identifying variations between American-born individuals and immigrants.
    METHODS: Participants were recruited from April-July 2022 through social media advertising and peer referral and surveyed about their sociodemographic and HIV-related behavioral characteristics. Previously validated scales were used to assess their HIV-related knowledge, risk perception, disclosure of sexual identity, experienced homophobia, and perceived racism within the sexual and gender minority community. Mann-Whitney-Wilcoxon tests were conducted to compare those born in the United States and those born abroad.
    RESULTS: Of the 112 participants, 26 (23.21%) were American-born individuals and 86 (76.79%) were immigrants. Despite similar levels of sexual risk behaviors, such as having multiple male sex partners, engaging in condomless anal sex, and using alcohol or drugs immediately before or during sex, immigrants had lower levels of HIV-related knowledge (p = .0480) and risk perception (p = .0114) compared to American-born individuals. Immigrants were also less likely to have disclosed their sexual identity to family, friends, and society compared to American-born individuals (p = .0004). No differences were identified with respect to experiences of homophobia (p = .2303) or perceptions of racism (p = .4011).
    CONCLUSIONS: Comprehensive HIV prevention efforts that address the social and cultural norms of South Asian GBM in the United States are needed.

    背景:研究表明,各种骨科手术后的抑郁和不良结局之间有很强的关联。然而,抑郁对三踝骨折切开复位内固定(ORIF)后并发症的影响尚未阐明.因此,本研究旨在确定抑郁是否与三踝骨折ORIF术后的再入院率和内科并发症发生率较高相关.
    方法:从1月开始的数据库查询,2020年3月,2021年,确定接受三踝ORIF的成年人产生了50154名患者。有抑郁症的人与没有抑郁症的对照组按年龄1:1匹配,性别,慢性阻塞性肺疾病,焦虑,和其他突出的合并症。主要终点比较90天全因再入院和医疗并发症。计算抑郁症对再入院和医疗并发症的影响的几率(ORs)。
    结果:接受三踝骨折ORIF治疗的抑郁症患者在初次手术后90天内再次入院的几率明显更高(OR:1.37;P<.0001)。与对照组患者相比,抑郁症患者发生医疗并发症的90天几率明显更高(OR:4.61;P<.0001)。
    结论:接受三踝ORIF治疗的抑郁症患者再次入院和多种术后并发症的风险增加。骨科医生应将抑郁因素纳入术前评估,考虑到三踝骨折ORIF后的并发症负担已经很高。
    III级:回顾性队列研究。
    BACKGROUND: Studies have suggested a strong association between depression and poor outcomes following various orthopaedic surgeries. However, depression\'s impact on complications following open reduction/internal fixation (ORIF) of trimalleolar fractures has not been elucidated. Therefore, this study aimed to determine whether depression is associated with higher rates of readmissions and medical complications following ORIF of trimalleolar fractures.
    METHODS: A database query from January, 2020, through March, 2021, identifying adults who underwent trimalleolar ORIF generated 50 154 patients. Those with depression were matched 1:1 to controls without depression by age, sex, chronic obstructive pulmonary disease, anxiety, and other prominent comorbidities. Primary endpoints compared 90-day all-cause readmissions and medical complications. Odds ratios (ORs) of the effect of depression on readmissions and medical complications were calculated.
    RESULTS: Patients with depression who underwent ORIF of trimalleolar fractures had significantly higher odds of being readmitted within 90 days of the initial procedure (OR: 1.37; P < .0001). Ninety-day odds of developing medical complications were significantly higher (OR: 4.61; P < .0001) in patients with depression compared with patients within the control group.
    CONCLUSIONS: Patients with depression undergoing trimalleolar ORIF face an increased risk of readmission and multiple postoperative complications. Orthopaedic surgeons should factor depression into their preoperative evaluation, given the already high burden of complications following ORIF of trimalleolar fractures.

    BACKGROUND: In the past 3 decades, thyroid cancer research has surged, becoming the leading topic in clinical thyroidology. Despite this, there\'s a lack of data identifying key articles, authors, and journals. This study aims to provide insights for authors, physicians, and research labs by highlighting the most influential journals, authors, and research topics in thyroid cancer.
    METHODS: A comprehensive search was conducted using the Scopus database, employing the medical subject heading (MeSH) terms \"Thyroid\" and \"Cancer\" in the titles, abstracts, or keywords of articles. The search was limited to English articles in academic medicine journals published between January 1993 and December 2021.
    RESULTS: The search yielded 21 472 articles across 3076 journals, authored by 13 974 senior authors. The number of journals publishing on thyroid cancer expanded from 29 in 1993 to 733 in 2021, marking an average annual growth of 14%. Article output on the topic increased from 54 in the initial year to 1580 by 2021, with an annual growth rate of 16%. A thematic analysis revealed 369 articles mentioning \"BRAF\" since 2004, 479 articles on \"ultrasound\" techniques, 325 on \"ablation\" methods, and 453 articles focusing on \"genetics\" in thyroid cancer. The Journal of Clinical Endocrinology and Metabolism emerged as the most prolific, publishing 1017 articles over the 29-year period.
    CONCLUSIONS: This study guides resource allocation towards impactful journals for thyroid cancer researchers, helps identify key contributors for collaboration or mentorship, and provides a framework for similar analyses in other fields.

    只有在过去的十年中,骨骼干细胞(SSC),一种细胞类型,显示出正式的干性证据,并作为成熟的骨骼细胞类型的最终起源,如成骨细胞,已定义。这里,我们讨论了一对最近的报告,这些报告确定SSC不代表单个细胞类型,而是一个相关细胞家族,每个细胞都有特征性的解剖位置和针对这些部位的生理学定制的不同功能。这些SSC的不同功能特性又为它们各自位置的疾病提供了基础。这一概念来自一份报告,该报告确定了一种独特的椎体骨骼干细胞驱动乳腺癌转移到其他骨骼部位的脊柱的高比率,以及一份报告,该报告确定了颅骨中两个SSC相互作用以介导生理性颅骨矿化和病理性颅骨缝合融合在颅骨融合中。尽管显示功能差异,这些SSC各自由共同的特征联合起来,包括一系列共同的表面标记和平行分化层次.我们建议SSC水平的这种多样性反过来转化为成熟骨骼细胞类型水平的相似多样性,包括成骨细胞,来自不同SSCs的成骨细胞各自表现出不同的功能和转录特征,反映了它们的细胞起源。在这个模型中,成骨细胞不代表单一的细胞类型,而是一个具有不同功能的相关细胞家族,与SSC中的功能多样性平行。
    只有在过去的十年中,骨骼中的干细胞才被鉴定出来。这里,我们讨论了一对最近的报告,这些报告确定骨骼干细胞实际上是一个相关细胞家族,每个细胞都有不同的位置和功能。这些位点特异性骨骼干细胞解释了在骨骼的不同区域中发生的标志性疾病。具体来说,这些干细胞之一形成脊柱,并确定该干细胞驱动乳腺癌转移到脊柱的其他骨骼部位的高比率。颅骨的扁平骨头中也至少有两个骨骼干细胞,突变提醒这两种干细胞如何相互“交谈”,从而导致颅骨过早融合的疾病。尽管它们的功能不同,这些干细胞都是由共同的特征,包括部分共享的系列标记基因。我们在这里还提出,骨骼干细胞水平的这种多样性转化为成熟骨骼细胞类型的相似多样性,包括成骨细胞.在这个模型中,成骨细胞不是单一的细胞类型,而是一个具有不同功能的相关细胞家族。
    Only in the past decade have skeletal stem cells (SSCs), a cell type displaying formal evidence of stemness and serving as the ultimate origin of mature skeletal cell types such as osteoblasts, been defined. Here, we discuss a pair of recent reports that identify that SSCs do not represent a single cell type, but rather a family of related cells that each have characteristic anatomic locations and distinct functions tailored to the physiology of those sites. The distinct functional properties of these SSCs in turn provide a basis for the diseases of their respective locations. This concept emerges from one report identifying a distinct vertebral skeletal stem cell driving the high rate of breast cancer metastasis to the spine over other skeletal sites and a report identifying two SSCs in the calvaria that interact to mediate both physiologic calvarial mineralization and pathologic calvarial suture fusion in craniosynostosis. Despite displaying functional differences, these SSCs are each united by shared features including a shared series of surface markers and parallel differentiation hierarchies. We propose that this diversity at the level of SSCs in turn translates into a similar diversity at the level of mature skeletal cell types, including osteoblasts, with osteoblasts derived from different SSCs each displaying different functional and transcriptional characteristics reflecting their cell of origin. In this model, osteoblasts would represent not a single cell type, but rather a family of related cells each with distinct functions, paralleling the functional diversity in SSCs.
    Only in the past decade have the stem cells in the skeleton been identified. Here, we discuss a pair of recent reports that identify that skeletal stem cells are actually a family of related cells that each have distinct locations and functions. These site-specific skeletal stem cells account for the signature diseases occurring in different regions of the skeleton. Specifically, one of these stem cells forms the spine and establishes that this stem cell drives the high rate of breast cancer metastasis to the spine over other skeletal sites. There are also at least two skeletal stem cells in the flat bones of the skull, with mutations alerting how these two stem cells “talk” to each other serving as a cause for disorders of premature skull fusion. Despite displaying differences in their function, these stem cells are each united by shared features including a partially shared series marker genes. We also here propose that this diversity at the level of skeletal stem cells translates into a similar diversity in mature skeletal cell types, including osteoblasts. In this model, osteoblasts are not a single cell type, but rather a family of related cells each with distinct functions.

    错过医疗预约是各专业的常见问题。护理的不连续导致计划外的医疗保健利用,增加成本,和不良的健康结果。先前评估小儿癫痫的研究表明,护理存在重大的社会经济障碍。在几个专业中,由于社会经济障碍,住院医师诊所的缺席率高于教师诊所。我们试图理解种族之间的关系,社会经济因素,并错过了大型三级护理医院儿科神经科住院医师诊所的预约。提取并分析了1年的居民诊所遭遇,以了解错过的预约,社会经济因素,和医疗保健利用。我们发现,错过预约发生在五分之一的患者中,并与社会经济因素相关(例如,收入和保险)和种族。与错过约会的社会经济因素相比,种族是更重要的因素。这些结果提供了针对和跟踪干预措施的领域,以改善儿科神经科诊所儿童的健康结果。
    Missed medical appointments are a common problem across specialties. The discontinuity of care leads to unplanned health care utilization, increased costs, and poor health outcomes. Previous studies evaluating pediatric epilepsy have shown significant socioeconomic barriers to care. In several specialties, resident clinic no-show rates are higher than faculty clinics because of socioeconomic barriers. We sought to understand the relationship between race, socioeconomic factors, and missed appointments in a pediatric neurology resident clinic at a large tertiary care hospital. Resident clinic encounters for 1 year were extracted and analyzed for missed appointments, socioeconomic factors, and health care utilization. We found that missed appointments occur for 1 in 5 patients and correlate with socioeconomic factors (eg, income and insurance) and race. Race was a more significant factor than socioeconomic factors for missed appointments. These results provide areas to target and track interventions to improve health outcomes in children in pediatric neurology clinics.

    背景:与艾滋病毒相关的耻辱,歧视,和社会边缘化破坏了最佳的艾滋病毒护理结果。更多的研究检查与艾滋病毒相关的耻辱的影响,歧视,其他互锁形式的压迫,和抗逆转录病毒治疗(ART)的依从性需要优化HIV治疗方案。这项研究使用多米尼加共和国两家诊所的数据来检查客户和医护人员(HCW)对艾滋病毒感染者中艾滋病毒和交叉污名的看法。
    方法:调查人口统计学,艾滋病毒相关的耻辱,歧视的各个方面(种族/族裔,艾滋病毒状况,性取向),医疗保健参与,从148名客户和131名HCWs收集了药物依从性。进行方差分析以检查临床上的污名差异,并使用逻辑回归来确定最佳客户药物依从性的预测因素。
    结果:在粗略和多变量逻辑回归模型中,医疗设施中由于客户的性取向而产生的感知歧视保留了显著性,并且与ART依从性呈负相关(aOR:0.79;95%CI:0.66,0.95)。
    结论:研究结果强调了实施消除污名化战略的重要性,歧视,和社会边缘化,特别是在医疗机构。
    BACKGROUND: HIV-related stigma, discrimination, and social marginalization undermines optimal HIV care outcomes. More research examining the impact of HIV-related stigma, discrimination, other interlocking forms of oppression, and antiretroviral therapy (ART) adherence is needed to optimize HIV treatment programming. This study uses data from two clinics in the Dominican Republic to examine client and healthcare worker (HCW) perceptions of HIV and intersectional stigmas among people living with HIV.
    METHODS: Surveys exploring demographics, HIV-related stigma, various dimensions of discrimination (race/ethnicity, HIV status, sexual orientation), healthcare engagement, and medication adherence were collected from 148 clients and 131 HCWs. Analysis of variance was conducted to examine differences in stigma by clinic and logistic regressions were used to determine predictors of optimal client medication adherence.
    RESULTS: Perceived discrimination in healthcare facilities due to clients\' sexual orientation retained significance in crude and multivariable logistic regression models and was negatively associated with ART adherence (aOR:0.79; 95% CI:0.66, 0.95).
    CONCLUSIONS: Findings highlight the importance of implementing strategies to address stigma, discrimination, and social marginalization, particularly within healthcare facilities.

    艾蒿是一种原产于东亚的多年生草本植物。它是一种重要的传统中药植物,以其浓郁的风味和药用作用而闻名。它含有丰富的活性成分,具有广泛的生物活性,包括消炎药,抗氧化剂,和免疫调节特性。2023年5月至7月,唐河县几个农场(约200亩)的艾吉发生了严重的叶腐病暴发(北纬32°46\'44\”,112°43'13''E),河南省,中国。发病率达到65%(n=200)。淡黄色斑点(直径1-2厘米)首先出现在叶子上,然后扩张形成不规则的黄褐色病变,最终导致整个叶子枯萎。收集患病的叶(30),并在感染和健康组织之间的区域中切成5×5mm2的片。将切下的植物组织在75%乙醇和1%次氯酸钠溶液中灭菌30秒零1分钟,分别。然后用无菌水冲洗组织并置于马铃薯葡萄糖琼脂(PDA)上,然后在25°C下孵育3天。分离的菌株属于镰刀菌属和链格孢属。致病性验证后,获得了25个纯化的镰刀菌菌株。三个代表性菌株(AC-Q,AC-X,来自不同地区的AC-Y)用于进一步研究。每个菌株都形成了丰富的气生菌丝体,最初是白色的,后来发展成紫色的色素。空中分生孢子稀疏分枝,以轮生phialides终止。大分生孢子纤细,直,测量为21.8至47.5×3.1至4.4μm,有两到四个隔片。微分生孢子为棒酸盐,测量值为8.31至11.6×2.1至3.5μm。形态特征与镰刀菌的物种描述一致(Sacc。)尼伦伯格1976年(莱斯利和萨姆梅雷尔,2006).rDNA内部转录间隔区(ITS),β-微管蛋白基因(tub2),翻译延伸因子1-α基因(tef1),calmodulin(cmdlet),扩增RNA聚合酶II最大亚基(rpb1)和RNA聚合酶II第二最大亚基(rpb2)以进行分子鉴定(O'Donnell等人。,2022年)。序列被保存在GenBank中,登录号为OR960548,OR960552,OR960555(ITS),OR972413,OR972414,OR972415(tub2),OR797685,OR797686,OR797687(tef1),OR972410,OR972411,OR972412(cmdlet),PP035106,PP035107,PP035108(rpb1),和PP035109、PP035110、PP035111(rpb2)。AC-Q序列的BLASTn分析显示出99%至100%的相似性与轮虫的序列(菌株CBS576.78)MT010888,rpb1的MT0109566和rpb2的MT010972。用串联序列构建了一个系统发育树(tub2,tef1,cmdlet,rpb1,rpb2),与使用邻居连接方法的类型菌株的序列一起。这三个菌株与轮虫的CBS576.78型菌株形成了进化枝,并与其他镰刀菌分离。这些形态学和分子鉴定表明该病原体为轮虫。通过用分生孢子悬浮液(106分生孢子ml-1)喷洒10个健康的2个月大的盆栽幼苗来测试致病性,和5个幼苗用灭菌水喷雾作为对照。将植物置于28°C和约90%的相对湿度的气候培养箱中。幼苗接种后十天,在处理过的植物上观察到典型的病变,除了对照组。通过形态学和分子鉴定,将重新分离的菌株鉴定为轮虫。履行科赫的假设。已知轮虫会导致玉米镰刀菌穗腐烂,以及中国其他植物的疾病,如芸苔属植物(Akram等人。,2020年)和荆棘(李等人。,2024).这是在世界范围内有关黄曲霉引起叶腐病的第一份报告。病原体的鉴定对于实施减少产量损失的管理方法至关重要。
    Artemisia argyi is a perennial herb native to East Asia. It is an important traditional Chinese medicinal plant known for its strong flavor and medicinal effects. It is rich in active ingredients and has a wide range of biological activities, including anti-inflammatory, antioxidant, and immune regulation properties. From May to July in 2023, a serious leaf rot outbreak occurred on A. argyi in several farms (approximately 200 acres) in Tanghe county (32°46\'44\" N, 112°43\'13\" E), Henan Province, China. The incidence rate reached 65% (n=200). Pale yellow spots (1-2 cm in diameter) first appeared on the leaves, then expanded to form irregular yellowish-brown lesions, eventually causing the entire leaves to wither. Diseased leaves (30) were collected and cut into 5 x 5 mm2 pieces in the areas between infected and healthy tissues. The excised plant tissues were sterilized in 75% ethanol and 1% sodium hypochlorite solution for 30 seconds and one minute, respectively. The tissues were then rinsed with sterile water and placed on potato dextrose agar (PDA) followed by incubating at 25 °C for 3 days. The isolated strains belonged to the genera Fusarium and Alternaria. After pathogenicity verification, 25 purified Fusarium strains were obtained. Three representative strains (AC-Q, AC-X, AC-Y) from different regions were used for further studies. Each strain formed abundant aerial mycelium that was initially white and later developed into purple pigments. Aerial conidiophores were sparsely branched, terminating with verticillate phialides. Macroconidia were slender, straight, and measured 21.8 to 47.5 × 3.1 to 4.4 μm, with two to four septa. Microconidia were clavate and measured 8.31 to 11.6 × 2.1 to 3.5 μm. Morphological characteristics were consistent with the species description of Fusarium verticillioides (Sacc.) Nirenberg 1976 (Leslie and Summerell, 2006). The rDNA internal transcribed spacer (ITS), β-tubulin gene (tub2), translation elongation factor 1-alpha gene (tef1), calmodulin (cmdA), RNA polymerase II largest subunit (rpb1) and RNA polymerase II second largest subunit (rpb2) were amplified for molecular identification (O\'Donnell et al., 2022). The sequences were deposited in GenBank with accession Nos. OR960548, OR960552, OR960555 (ITS), OR972413, OR972414, OR972415 (tub2), OR797685, OR797686, OR797687 (tef1), OR972410, OR972411, OR972412 (cmdA), PP035106, PP035107, PP035108 (rpb1), and PP035109, PP035110, PP035111 (rpb2). BLASTn analysis of AC-Q sequences exhibited 99 to 100% similarity with F. verticillioides sequences (strains CBS 576.78) MT010888 of cmdA, MT0109566 of rpb1, and MT010972 of rpb2. A phylogenetic tree was constructed with concatenated sequences (tub2, tef1, cmdA, rpb1, rpb2), alongside the sequences of the type strains using the neighbor-joining method. The three strains formed a clade with the type strain CBS 576.78 of F. verticillioides, and were separated from other Fusarium spp. These morphological and molecular identifications indicated that the pathogen was F. verticillioides. Pathogenicity was tested on 10 healthy 2-month-old potted seedlings by spraying them with a conidial suspension (106 conidia ml-1), and 5 seedlings were sprayed with sterilized water as a control. The plants were placed in a climate incubator at 28°C and a relative humidity of approximately 90%. Ten days after seedling inoculation, typical lesions were observed on the treated plants, except in the control group. The reisolated strains were identified as F. verticillioides by morphological and molecular characterization, fulfilling Koch\'s postulates. F. verticillioides is known to cause Fusarium ear rot on maize, as well as diseases on other plants in China such as Brassica rapa (Akram et al., 2020) and Schizonepeta tenuifolia (Li et al., 2024). This is the first report of F. verticillioides causing leaf rot on A. argyi worldwide. Identification of the pathogen is crucial for implementing management approaches to reduce yield losses.
