    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: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.

    背景:肌肉减少症是一种进行性和全身性骨骼肌疾病,与住院风险增加和对生存的不利影响相关。本研究旨在使用修订后的欧洲老年人肌肉减少症工作组(EWGSOP2)定义,调查艾滋病毒感染者中肌肉减少症的患病率和相关危险因素。
    方法:这项包括379例确诊HIV感染患者的横断面研究通过使用生物电阻抗分析方法评估了阑尾骨骼肌质量。使用五次坐立测试和定时的“UpandGo”测试分析了肌肉力量和功能活动性。
    结果:根据修订的EWGSOP2定义,艾滋病毒感染者中前期肌肉减少症和肌肉减少症的患病率分别为3.4%和2.1%。高龄(赔率比1.07,p=.03),较低的体重指数(比值比0.79,p=.012)和低于500/μl的CD4+T细胞计数(比值比2.22,p=.007)被确定为与肌肉减少症相关的显著因素。肌肉减少症也被确定为虚弱的显著相关(p<.001)。
    结论:这是第一项根据修订的EWGSOP2临床算法检查HIV感染者中肌肉减少症患病率的研究。高龄,较低的体重指数和较差的免疫状态被确定为肌肉减少症的促进因素。肌肉减少症与虚弱显著相关。标准化的临床算法对于HIV感染者可靠的肌少症诊断至关重要,以促进干预策略并防止不良健康结果。
    BACKGROUND: Sarcopenia is a progressive and systemic skeletal muscle disorder associated with an increased risk of hospitalization and adverse effects on survival. This study aims to investigate the prevalence and related risk factors of sarcopenia in people living with HIV using the revised European Working Group on Sarcopenia in Older People (EWGSOP2) definition.
    METHODS: This cross-sectional study comprising 379 patients with confirmed HIV infection evaluated the appendicular skeletal muscle mass by employing the bioelectrical impedance analysis method. Muscle strength and functional mobility were analyzed using the five-time sit-to-stand test and the timed \"Up and Go\" test.
    RESULTS: The prevalence rates of pre-sarcopenia and sarcopenia among people living with HIV were 3.4 % and 2.1 % according to the revised EWGSOP2 definition. Advanced age (Odds Ratio 1.07, p = .03), lower body mass index (Odds Ratio 0.79, p = .012) and CD4+ T-cell count below 500/μl (Odds Ratio 2.22, p = .007) were identified as significant factors associated with sarcopenia. Sarcopenia was also identified as a significant correlate of frailty (p < .001).
    CONCLUSIONS: This is the first study examining the prevalence of sarcopenia in people living with HIV according to the revised EWGSOP2 clinical algorithm. Advanced age, lower body mass index and a poor immune status are determined as promoting factors of sarcopenia. Sarcopenia significantly correlates with frailty. Standardized clinical algorithms are essential for reliable sarcopenia diagnosis in people living with HIV in order to promote intervention strategies and to prevent adverse health outcomes.

    在中国,圆环病毒属中的一种新病原体已被鉴定为大菱头鱼(ScophthhthalmusmaximusL.)水产养殖种群中“新型急性出血综合征”(NAHS)的病原体。使用光学显微镜的组织病理学检查显示心脏内广泛的坏死,脾,和患病鱼的肾组织。利用透射电子显微镜(TEM),我们检测到这些细胞的细胞质中存在圆环病毒颗粒,病毒粒子始终表现出直径为20-40nm的球形形态。TEM检查证实了这些病毒体在心脏中的优势,脾,脾还有肾.随后通过聚合酶链反应(PCR)分析进行的分子表征证实了TEM的发现,在上述组织中有阳性信号,与对ill缺乏检测形成鲜明对比的是,fin,肝脏,和肠道组织。TEM观察,由PCR电泳数据支持,强烈建议脾脏和肾脏是病毒感染的主要目标。使用生物物理进一步表征,生化化验,基因组测序证实了圆环病毒属的病毒分类,导致大菱头圆环病毒(TurCV)的命名。目前的研究努力揭示这种病原体的发病机理,提供对TurCV在这种新型猪宿主中的感染机制的见解,从而有助于更广泛地了解其对大菱头鱼健康和水产养殖的影响。
    In China, a novel pathogen within the genus Circovirus has been identified as a causative agent of the \'novel acute hemorrhage syndrome\' (NAHS) in aquacultured populations of turbot (Scophthalmus maximus L.). Histopathological examination using light microscopy revealed extensive necrosis within the cardiac, splenic, and renal tissues of the afflicted fish. Utilizing transmission electron microscopy (TEM), we detected the presence of circovirus particles within the cytoplasm of these cells, with the virions consistently exhibiting a spherical morphology of 20-40 nm in diameter. TEM inspections confirmed the predominance of these virions in the heart, spleen, and kidney. Subsequent molecular characterization through polymerase chain reaction (PCR) analysis corroborated the TEM findings, with positive signals in the aforementioned tissues, in stark contrast to the lack of detection in gill, fin, liver, and intestinal tissues. The TEM observations, supported by PCR electrophoresis data, strongly suggest that the spleen and kidney are the primary targets of the viral infection. Further characterization using biophysical, biochemical assays, and genomic sequencing confirmed the viral classification within the genus Circovirus, resulting in the nomenclature of turbot circovirus (TurCV). The current research endeavors to shed light on the pathogenesis of this pathogen, offering insights into the infection mechanisms of TurCV in this novel piscine host, thereby contributing to the broader understanding of its impact on turbot health and aquaculture.

    我们报告了一名42岁女性,确诊为复发性生殖器疱疹(HSV-2),在阿昔洛韦400mg每天两次的抑制性抗病毒治疗中得到了很好的控制。患者需要减肥手术以管理被认为危险的高BMI。进行了Roux-en-Y手术,有效地减轻了她的体重;然而,术后疱疹抑制变得无效,严重的疱疹相关并发症,尽管阿昔洛韦的总剂量和频率从每天两次增加到每天三次。通过每天两次将治疗更改为伐昔洛韦500mg,可以恢复完全的疱疹控制。Roux-en-Y手术是最常见的减肥手术形式。可以从已知的它们的性质和吸收位点来预测不同疱疹抗病毒药物的功效的后果。通过术前治疗的预期变化,可以避免类似的疱疹病毒抑制问题。
    We report a 42-year-old female with confirmed recurrent genital herpes (HSV-2), which was well controlled on suppressive antiviral therapy with aciclovir 400 mg twice daily. The patient required bariatric surgery in order to manage what was deemed a dangerously high BMI. A Roux-en-Y procedure was performed which effectively reduced her weight; however, herpes suppression become ineffective post operatively, with serious herpes related complications, despite increasing the total dose of aciclovir and the frequency from twice daily to three times a day. Complete herpes control was restored by changing therapy to valaciclovir 500 mg twice daily. The Roux-en-Y procedure is the most common form of bariatric surgery. Consequences on the efficacy of different herpes antivirals can be predicted from what is known of their properties and sites of absorption. Similar problems with herpes virus suppression may be avoided by an anticipated change in therapy preoperatively.

    很少报道在免疫活性无反应者中对乙型肝炎疫苗接种发展急性乙型肝炎。我们在一名79岁的异性恋男性中报告了这种情况。有证据表明,替诺福韦酯/恩曲他滨作为初级预防可以预防乙型肝炎的获得在艾滋病毒暴露前预防(PrEP)与替诺福韦酯/恩曲他滨的当前时代,有预防艾滋病毒和乙型肝炎的双重好处。我们讨论了考虑替诺福韦酯/恩曲他滨暴露前预防的重要性,在那些乙肝疫苗接种无反应的人在获得乙型肝炎的高风险
    Developing acute hepatitis B in immunocompetent non-responders to hepatitis B vaccination has been rarely reported. We report such a case in a 79 year old heterosexual male. There is evidence that tenofovir disoproxil/emtricitabine as primary prophylaxis can prevent acquisition of hepatitis B. In the current era of HIV pre-exposure prophylaxis (PrEP) with tenofovir disoproxil/emtricitabine, there is dual benefit of preventing HIV and hepatitis B. We discuss the importance of considering tenofovir disoproxil/emtricitabine pre-exposure prophylaxis in those hepatitis B vaccination non-responders at high risk of acquiring hepatitis B.

    唐氏综合征患者的免疫系统失调被认为在许多临床表现的病理生理学中起主要作用。与纽约西奈山卫生系统的2605名患者对照队列相比,这项疾病自然史研究对1299名唐氏综合症患者的不同免疫相关诊断的患病率进行了综合评估。在过去的18年里,纽约。我们对本章接受诊断的几率进行了逐步分析,ICD-CM-10代码系统的子章节和诊断级别。我们的唐氏综合征队列中的个体诊断为炎症和自身免疫表现如斑秃的几率较高(OR6.06,p=0.01),其他败血症(OR4.79,p<0.001,紫癜和其他出血性疾病(OR2.31,p<0.001),和酒渣鼻(OR3.11,p<0.001)。他们还提出了较低的概率诊断为疱疹病毒感染(OR0.42,p=0.01),和病毒性疣(OR0.51,p=0.04)。我们认为唐氏综合症患者的免疫系统失调对传染病有影响,包括降低病毒性疾病的发病率和增加其严重程度。我们的数据还表明炎症和自身免疫介导的疾病,特别是皮肤,在唐氏综合症患者中加剧。最后,唐氏综合征患者人群中可能需要更多地关注非突发疾病,因为这些疾病也会极大地影响生活质量.
    Dysregulation of the immune system in individuals with Down syndrome is thought to play a major role in the pathophysiology of many clinical presentations. This natural history of disease study took a comprehensive evaluation of the prevalence of different immune related diagnoses in a cohort of 1299 patients with Down syndrome compared to a 2605 patient control cohort at the Mount Sinai Health System in New York, NY over the past 18 years. We conducted a stepwise analysis of the odds of receiving a diagnosis at the Chapter, Sub-chapter and Diagnosis level of the ICD-CM-10 code system. Individuals in our Down syndrome cohort had higher odds of a diagnosis with inflammatory and autoimmune presentations such as Alopecia areata (OR 6.06, p = 0.01), Other sepsis (OR 4.79, p < 0.001, Purpura and other hemorrhagic conditions (OR 2.31, p < 0.001), and Rosacea (OR 3.11, p < 0.001). They also presented with lower odds of a diagnosis of Herpesviral infection (OR 0.42, p = 0.01), and Viral warts (OR 0.51, p = 0.04). We posit that dysregulation of the immune system in individuals with Down syndrome has impact on infectious diseases, including lowering the incidence of viral disease and increasing its severity. Our data also suggests inflammation and autoimmune mediated diseases, in particular of the skin, are exacerbated in individuals with Down syndrome. Finally, there may be a need for greater clinical attention to non-emergent conditions within the Down syndrome patient population as those can also greatly affect quality of life.

    背景:性健康研究的招募具有挑战性。这项研究探讨了同意联系系统(C4C)的潜力-研究接触的通用同意-以改善参与者的招募和参与性健康研究。我们的目标是了解患者和工作人员对研究的理解,他们对单独的C4C系统的看法,以及他们在性健康诊所环境中对其可接受性的偏好。
    方法:一项两阶段研究于2021年11月至2022年7月在英国一家大型城市性健康诊所进行。第一阶段涉及对所有患者和工作人员进行自我填写的问卷。在阶段2中,半结构化访谈(SSIs)进一步探讨了患者的担忧和偏好。使用卡方和Fisher精确检验对调查数据进行分析,并将主题分析应用于自由文本响应和SSI。
    结果:总共完成了205/300名患者(68%)和41/280名工作人员(15%)的问卷调查。参与研究的动机包括利他主义和个人兴趣。在保密性和预期的参与压力方面,患者和工作人员之间存在统计学上的显着差异。大多数工作人员(n=38,93%)和一半的患者(n=100,49%)支持实施性健康C4C系统。参与者认识到性健康C4C系统的潜在好处,包括增强隐私和增加研究机会。人们对耻辱提出了担忧,术语,和注册方法。
    结论:这项研究发现,C4C系统有可能增强参与者招募和参与性健康研究,但是实施支持与隐私和注册过程的担忧之间存在狭隘的分歧。这些见解需要以患者为中心的设计方法,强调清晰的沟通和隐私。未来的研究应侧重于实施和评估性健康C4C系统,以进一步探索其在不同情况下的有效性和可接受性。
    BACKGROUND: Recruitment in sexual health research is challenging. This study explores the potential of a Consent for Contact system (C4C) - generic consent for research contact - to improve participant recruitment and engagement in sexual health research. Our objectives were to understand patient and staff understanding of research, their views on a separate C4C system, and their preferences for its acceptability in a sexual health clinic setting.
    METHODS: A two-stage study was conducted at a large urban UK sexual health clinic from November 2021 to July 2022. Stage one involved a self-completed questionnaire administered to all patients and staff. In Stage 2, semi-structured interviews (SSIs) further explored patient concerns and preferences. Survey data were analysed using chi-square and Fisher\'s exact test and thematic analysis was applied to free-text responses and SSIs.
    RESULTS: A total of 205/300 patient (68%) and 41/280 staff questionnaires (15%) were completed. Motivations for research participation included altruism and personal interest. Statistically significant differences were found between patients\' and staff members\' concerns on confidentiality and anticipated feeling of pressure to participate. The majority of staff (n = 38, 93%) and half of patients (n = 100, 49%) supported implementation of a sexual health C4C system. Participants recognised the potential benefits of a sexual health C4C system, including enhanced privacy and increased research opportunities. Concerns were raised about stigma, terminology, and signing-up methods.
    CONCLUSIONS: This study found the C4C system has the potential to enhance participant recruitment and engagement in sexual health research, but implementation support is narrowly divided with concerns around privacy and sign-up processes. These insights call for a patient-centred design approach, emphasising clear communication and privacy. Future research should focus on implementing and evaluating a sexual health C4C system to further explore their effectiveness and acceptability in different contexts.

    背景:性传播感染(STIs)是全球主要的公共卫生问题。未经治疗的性传播感染可能会有严重的后遗症,尤其是孕妇。这项研究的目的是评估孟加拉国妊娠期妇女筛查和治疗常见性传播感染的可行性和可接受性。
    方法:在达卡为中下阶层人口服务的四家妇产科诊所/医院招募妇女,孟加拉国。参与者接受了采访,和阴道拭子样本由临床工作人员收集。对标本进行了淋病奈瑟菌检测,沙眼衣原体,使用GeneXpert(造父变星,桑尼维尔,California).妇女被告知她们的测试结果,并接受可治愈感染的治疗。进行固化测试。
    结果:在1157名孕妇中,1000人(86.4%)参加。百分之九十一的女性在测试的同一天得知了自己的测试结果。在996个有效结果中,沙眼衣原体检测呈阳性的有7例(0.7%),阴道毛滴虫检测呈阳性的有1例(0.1%)。没有淋病病例。在971名获得高风险HPV有效结果的女性中,46(4.7%)检测呈阳性。
    结论:在孟加拉国,在产前护理期间对女性进行性传播感染筛查是非常可行和广泛接受的。虽然常见的可治愈性传播感染的患病率很低,hrHPV感染率中等偏高。我们的发现支持孟加拉国性传播感染的定期监测和持续的宫颈癌预防工作。
    BACKGROUND: Sexually transmitted infections (STIs) are a major public health concern worldwide. Untreated STIs may have serious sequelae, particularly in pregnant women. The objective of this study was to assess the feasibility and acceptability of screening and treating common STIs in women during pregnancy in Bangladesh.
    METHODS: Women were enrolled from four maternity clinics/hospitals serving the lower-middle class population in Dhaka, Bangladesh. The participants were interviewed, and vaginal swab samples were collected by clinical staff. Specimens were tested for Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis and high-risk Human Papilloma Viruses (HPVs) using GeneXpert (Cepheid, Sunnyvale, California). Women were informed of their test results and were provided treatment for curable infections. A test of cure was performed.
    RESULTS: Out of 1157 pregnant women approached, 1000 (86.4%) participated. Ninety-one percent women learned of their test results on the same day of testing. Out of the 996 valid results, 7 (0.7%) tested positive for Chlamydia trachomatis and 1 (0.1%) for Trichomonas vaginalis. There were no gonorrhoea cases. Out of the 971 women with valid results for high-risk HPVs, 46 (4.7%) tested positive.
    CONCLUSIONS: Screening women for STIs during antenatal care was highly feasible and well-accepted in Bangladesh. While the prevalence of common curable STIs was very low, hrHPV infection prevalence was moderately high. Our findings support period monitoring of STIs and continued prevention efforts for cervical cancer in Bangladesh.
