    HIV感染及其治疗与线粒体功能障碍和代谢紊乱有关。然而,氧化磷酸化活性的纵向变化[复合物I(C1)和复合物IV(C4)],或静脉乳酸/丙酮酸比率(LPR),以及它们与胰岛素抵抗(IR)的关系,在患有围产期获得性HIV(YPMiv)的年轻人中,尚不清楚。我们测量了静脉LPR,血细胞中的C1和C4活性以及IR的稳态模型评估(HOMA-IR)超过两年。在YPMiv与围产期暴露于HIV但未感染的年轻人中,观察到线粒体相关测量和IR的纵向差异有限。组间C1、C4或HOMA-IR无系统性差异。
    HIV infection and its treatment are associated with mitochondrial dysfunction and metabolic derangement. However, longitudinal changes in oxidative phosphorylation activities [Complex I (C1) and Complex IV (C4)], or venous lactate/pyruvate ratios (LPR), and their relationships with insulin resistance (IR), remain unclear in youth living with perinatally-acquired HIV (YPHIV). We measured venous LPR, C1, and C4 activities in blood cells and homeostatic model assessment for IR (HOMA-IR) over two years. Limited longitudinal differences in mitochondrial-related measures and IR were observed in YPHIV vs youth perinatally HIV-exposed but uninfected. There were no systematic differences in C1, C4, or HOMA-IR between the groups.

    描述:纽约州卫生部(NYSDOH)建议所有怀孕的患者在怀孕期间接受人类免疫缺陷病毒(HIV)筛查。这项研究评估了重复产前HIV检测的患病率以及与接受推荐检测相关的因素。方法:使用NYSDOH新生儿筛查计划的数据随机选择2017年分娩的无HIV孕妇。重复测试的接收被定义为在第一或第二三个月的初始HIV测试和在第三三个月的最终(放松);或在第一三个月的初始测试和在第三三个月的最终(严格)。在双变量分析中计算相对风险(RR)和95%置信区间。计算调整后的RR以确定人口统计学和临床因素与接受重复HIV检测之间的关联。结果:该队列包括2,225名个体。大约四分之一(24%)在第一或第二和第三三个月接受了推荐的测试,17%在第一和第三三个月接受了这些测试。报告西班牙裔或亚洲种族/种族的个人,有政府资助的保险,在孕早期开始产前护理,在纽约市交付,或接受产前丙型肝炎病毒筛查的患者更有可能接受任一定义的重复检测.结论:尽管有好处和成本效益,妊娠晚期重复产前HIV筛查的患病率仍然持续较低.改善信息传递以及有针对性的教育和资源,以协助产前提供者,可以加强重复检测的重要性,并减少围产期艾滋病毒的残留传播。
    Description: New York State Department of Health (NYSDOH) recommends that all pregnant patients receive human immunodeficiency virus (HIV) screening during pregnancy. This study assessed the prevalence of repeat prenatal HIV testing and factors associated with receipt of the recommended tests. Methods: Data from the NYSDOH newborn screening program were used to randomly select pregnant persons without HIV who delivered a liveborn infant in 2017. Receipt of repeat testing was defined as an initial HIV test in the first or second trimesters and the final in the third trimester (relaxed); or an initial test in the first trimester and the final in the third trimester (strict). Relative risks (RRs) and 95% confidence intervals were calculated in bivariate analyses. Adjusted RRs were calculated to determine associations between demographic and clinical factors and receipt of repeat HIV testing. Results: The cohort included 2,225 individuals. Roughly one quarter (24%) received the recommended tests in the first or second and third trimesters and 17% received them in the first and third trimesters. Individuals who reported Hispanic or Asian race/ethnicities, had government-funded insurance, started prenatal care in the first trimester, delivered in New York City, or received prenatal hepatitis C virus screening were significantly more likely to receive repeat testing using either definition. Conclusions: Despite the benefits and cost-effectiveness, the prevalence of repeat prenatal HIV screening during the third trimester remains persistently low. Improved messaging and targeted education and resources to assist prenatal providers could reinforce the importance of repeat testing and reduce residual perinatal HIV transmission.

    关于2019年感染艾滋病毒和冠状病毒疾病(COVID-19)的儿童和青少年的数据有限。收集了与围产期获得性HIV(ALPMiv)患者和最初参加HIV早期抗逆转录病毒治疗(CHER)儿童研究的青少年中COVID-19感染相关的临床和抗体数据。我们提供了对53种ALPMiv进行了抗SARS-CoV-2抗体测试的描述性分析。接受测试的青少年中有超过一半(53%)的抗SARS-CoV-2抗体呈阳性,只有一名参与者描述了可能的症状感染史。
    该研究有助于了解HIV阳性青少年的SARS-CoV-2感染和疫苗接种实践。
    Data on children and adolescents with HIV and coronavirus disease 2019 (COVID-19) co-infection are limited. Clinical and antibody data related to COVID-19 infection in adolescents living with perinatally acquired HIV (ALPHIV) and originally enrolled in the Children with HIV Early Antiretroviral Therapy (CHER) study were collected. We present a descriptive analysis of 53 ALPHIV who were tested for anti-SARS-CoV-2 antibodies. Just over half (53%) of the adolescents tested had positive anti-SARS-CoV-2 antibodies with only one participant describing a prior history of possible symptomatic infection.
    UNASSIGNED: The study contributes to the understanding of SARS-CoV-2 infection and vaccination practices in HIV-positive adolescents.

    在撒哈拉以南非洲,在围产期感染艾滋病毒(APHIV)的青少年中扩大抗逆转录病毒治疗(ART)二十多年后,由于多因素导致死亡率和发病率增加,ART的长期依从性仍然较差.关于影响长期坚持ART的家庭和结构因素的数据很少。采用定性探索性设计,对在林波波省Vhembe区农村医疗机构接受艾滋病毒护理和管理的21名APHIV患者进行了深入访谈,南非。成绩单被逐字翻译成英文,并使用Tesch的8个定性数据分析步骤对数据进行分析。样本包括10-19岁的APHIV,他们知道自己的HIV状况,他们都接受了超过5年的ART治疗。他们住在延长,中断,祖父母和儿童为户主的家庭。他们经历了由于贫困或孤儿而导致的食物不安全感,以及生活在混乱的家庭中,这阻止了他们长期坚持。此外,依赖社会支持赠款来维持他们的生计影响了长期坚持。APHIV面临着结构性因素的挑战,例如不一致的诊所出勤率,学校活动和诊所预约之间的冲突,缺乏去诊所的交通费,这影响了坚持。尽管APHIV服用了一粒固定剂量的ART,由于各种家庭原因,他们无法长期坚持,结构,和心理社会挑战。除了基于机构的干预之外,有家庭的需要,以社区为基础,和多部门干预措施,以支持APHIV的长期ART依从性。
    After more than two decades of the expansion of antiretroviral treatment (ART) in adolescents living with perinatal HIV (APHIV) in sub-Saharan Africa, there is still poorly sustained long-term adherence to ART due to multifactorial factors with the consequence of increased mortality and morbidity. There are little data available on the familial and structural factors which affect sustenance to long-term adherence to ART. A qualitative exploratory design was used to conduct in-depth interviews with 21 APHIV attending HIV care and management in the rural health facilities of Vhembe district in Limpopo Province, South Africa. Transcripts were translated verbatim into English, and data were analyzed using Tesch\'s eight steps of qualitative data analysis. The sample consisted of APHIV 10-19 years old who were aware of their HIV status, and all had received ART for more than 5 years. They lived in extended, disrupted, grandparent- and child-headed households. They experienced food insecurities due to poverty or orphanhood, as well as living in disrupted households, which deterred them from long-term adherence. In addition, dependency on social support grants to sustain their livelihoods affected long-term adherence. APHIV had challenges with structural factors such as inconsistent clinic attendance, clashes between school activities and clinic appointments, and the lack of transport fare to the clinic, which affected adherence. Although APHIV were on one-pill fixed-dose ART, they were not able to sustain long-term adherence due to various familial, structural, and psychosocial challenges. In addition to institution-based interventions, there is a need for family, community-based, and multi-sectorial interventions to support long-term ART adherence among APHIV.

    背景:尼日利亚尽管儿科HIV感染率很高,但婴儿早期诊断(EID)对HIV的摄取较低。增加HIVEID的努力受到许多因素的限制。这项研究评估了EID的吸收和挑战服务提供者在为暴露于HIV的婴儿提供常规护理方面的经验。
    方法:这是拉各斯州初级保健中心(PHCs)的混合方法研究,尼日利亚。研究的定量组成部分是对拉各斯州22个PHC的目的性样本中的PMTCT婴儿随访登记册的回顾。返回干血液样本(DBS)的艾滋病毒暴露婴儿(HEI)的数量,收集日期,并且在研究电子数据捕获(RedCap)上捕获了研究前一年的婴儿EID结果。对每个参与的PHC有目的地选择的服务提供商进行了深入访谈。使用MAXQDA2020(VERBI软件,2019)。
    结果:22个拉各斯州初级保健中心参与了这项研究。15个PHC(68.2%)接受了PMTCTHIV咨询和婴儿随访记录。在12个(54.6%)PHC中观察到DBS样品收集的记录。仅在9个(40.9%)PHC中观察到DBS样品收集和EID结果记录。深入访谈揭示了孕产妇和卫生系统对EID的挑战。据报道,否认艾滋病毒感染是阻碍使用EID服务的唯一孕产妇因素。卫生系统面临的挑战包括EID服务的不可用,关于EID是否在设施中执行的不确定性,转介到二级医疗机构接受EID服务(导致后续行动损失),并延迟获得EID的结果。建议护士将DBS收集任务转移,以增加对EID服务的访问。
    结论:有必要扩大EID服务,解决女性否认HIV感染的问题。强调为妇女提供咨询和与现有服务的联系。有人指出,对卫生工作者进行有关DBS收集的再培训以及对EID服务的适当记录是改善该州早期婴儿艾滋病毒诊断实施的关键。
    BACKGROUND: Nigeria has a low uptake of early infant diagnosis (EID) of HIV despite its high pediatric HIV infection rate. Efforts to increase the EID of HIV have been limited by many factors. This research assessed EID uptake and challenges service providers experienced in providing routine care for HIV-exposed infants.
    METHODS: This is a mixed-method study at primary health centers (PHCs) in Lagos state, Nigeria. The quantitative component of the research was a review of the PMTCT Infant Follow-up Register at a purposive sample of 22 PHCs of Lagos State. The number of HIV-exposed infants (HEIs) returned for a dried blood sample (DBS) collection, date of collection, and the infant\'s EID results for one year preceding the study were captured on Research Electronic Data Capture (RedCap). In-depth interviews were conducted with service providers purposively selected per participating PHC. Electronic transcripts were analyzed using MAXQDA 2020 (VERBI Software, 2019).
    RESULTS: Twenty-two Lagos State primary health centers participated in the research. Fifteen PHCs (68.2%) had PMTCT HIV counseling and Infant follow-up registers. Documentation of DBS sample collection was observed in 12 (54.6%) PHCs. Both DBS sample collection and EID results documentation were observed in only nine (40.9%) PHCs. In-depth interviews revealed both maternal and health systems\' challenges to EID. The denial of HIV status was the only maternal factor reported as a barrier against the use of EID services. Health systems challenges include unavailability of EID services, uncertainty regarding whether EID is performed in a facility, referral to secondary health facilities for EID services (leading to losses to follow-up), and delay in getting results of EID. Task-shifting of DBS collection by nurses was suggested as means to increase access to EID services.
    CONCLUSIONS: There is a need to expand EID services and address women\'s denial of HIV infection. Counseling women and linkage to available services are emphasized. Re-training of health workers on DBS collection and proper documentation of EID services were noted as key to improving the implementation of early infant diagnosis of HIV in the state.

    围产期艾滋病毒传播仍然是一个重大的公共卫生挑战,估计每年有16万儿童新感染艾滋病毒。公共卫生护士通过有针对性的干预措施,如识别感染艾滋病毒的孕妇,在预防和消除围产期艾滋病毒传播方面发挥着关键作用。转诊和与护理挂钩,提供抗逆转录病毒治疗,以及对母亲和婴儿的后续护理和保留。然而,成功实施存在重大障碍,包括污名和歧视,获得医疗服务的机会有限,社会经济因素,和有限的资源。解决这些障碍需要采取多方面的方法,包括政策变化,社区参与,为受影响的家庭提供有针对性的支持和资源。在这篇评论文章中,我们概述了围产期艾滋病毒传播的流行病学,当前的预防和消除战略,以及公共卫生护士在这些工作中的重要作用。我们还将讨论成功实施公共卫生护士干预措施的障碍以及该领域研究和实践的未来方向。最终,围产期预防和消除艾滋病毒的目标只能通过跨多个部门和利益攸关方的持续合作努力来实现,公共卫生护士在这项工作中发挥着至关重要的作用。
    Perinatal HIV transmission remains a significant public health challenge, with an estimated 160,000 children newly infected with HIV each year. Public health nurses play a critical role in the prevention and elimination of perinatal HIV transmission through targeted interventions such as identification of pregnant women with HIV, referral and linkage to care, provision of antiretroviral therapy, and follow-up and retention in care for both mothers and infants. However, significant barriers to successful implementation exist, including stigma and discrimination, limited access to healthcare services, socioeconomic factors, and limited resources. Addressing these barriers will require a multifaceted approach that includes policy changes, community engagement, and targeted support and resources for affected families. In this review article, we provide an overview of the epidemiology of perinatal HIV transmission, current strategies for prevention and elimination, and the vital role of public health nurses in these efforts. We will also discuss the barriers to the successful implementation of public health nurse interventions and the future directions for research and practice in this field. Ultimately, the goal of perinatal HIV prevention and elimination can only be achieved through a sustained and collaborative effort across multiple sectors and stakeholders, with public health nurses playing a crucial role in this effort.

    确定患有围产期获得性HIV(YAPHIV)的年轻人的感知社会支持与病毒抑制之间的关系。
    我们将YAPHIV≥18年纳入AMPUp,一项关于PHACS(儿科HIV/AIDS队列研究)的研究,与社会支持评估和≥1HIV病毒载量(VL)在未来一年测量。我们评估了情绪,器乐,和友谊社会支持通过NIH工具箱。我们定义了社会支持,在研究进入和第3年测量(如果有的话),低(T分数≤40),平均(41-59)或高(≥60)。我们将病毒抑制定义为社会支持措施后一年内所有VL<50拷贝/mL。我们使用广义估计方程拟合多变量泊松回归模型,并评估了从儿科护理到成人护理的过渡作为效果调节剂。
    在444YAPHIV中,37%的人报告说,入境时的情感和工具支持和友谊很低,32%和36%。在接下来的一年里,44%被病毒抑制。在第3年数据的136人中,45%被压制。所有三种社会支持措施的平均水平或高水平与更高的病毒抑制可能性相关。在儿科患者中,仪器支持与病毒抑制相关(平均/高与低支持的患者中被抑制的调整比例=51.2%vs28.9%;风险比(RR)=1.77,95%置信区间(CI)=1.37,2.29),但不是成人护理(40.0%vs40.8%;RR=0.98,95%CI=0.67,1.44)。
    足够的社会支持增加了YAPHIV病毒抑制的可能性。随着YAPHIV为成人临床护理过渡做准备,增强社会支持的策略可能会促进病毒抑制。
    UNASSIGNED: To determine the relationship between perceived social support and viral suppression among young adults with perinatally-acquired HIV (YAPHIV).
    UNASSIGNED: We included YAPHIV ≥18 years enrolled in AMP Up, a study of PHACS (Pediatric HIV/AIDS Cohort Study), with social support evaluations and ≥1 HIV viral load (VL) measured over the next year. We evaluated emotional, instrumental, and friendship social support via the NIH Toolbox. We defined social support, measured at study entry and year 3 (if available), as low (T-score ≤40), average (41-59) or high (≥60). We defined viral suppression as all VL <50 copies/mL over the one year after social support measures. We fit multivariable Poisson regression models using generalized estimating equations, and evaluated transition from pediatric to adult care as an effect modifier.
    UNASSIGNED: Among 444 YAPHIV, low emotional and instrumental support and friendship at entry were reported by 37%, 32% and 36%. Over the next year, 44% were virally suppressed. Of 136 with year 3 data, 45% were suppressed. Average or high levels of all three social support measures were associated with higher likelihood of viral suppression. Instrumental support was associated with viral suppression among those in pediatric (adjusted proportion suppressed among those with average/high vs low support=51.2% vs 28.9%; risk ratio (RR)=1.77, 95% confidence interval (CI)=1.37, 2.29), but not adult care (40.0% vs 40.8%; RR=0.98, 95% CI=0.67, 1.44).
    UNASSIGNED: Sufficient social support increases likelihood of viral suppression among YAPHIV. Strategies to enhance social support may promote viral suppression as YAPHIV prepare for adult clinical care transition.

    我们以前已经表明,围产期感染艾滋病毒(PHIVl+)的青少年加速衰老,基于表观遗传年龄和实际年龄之间的差异。目前的研究调查了表观遗传衰老的后续纵向模式以及表观遗传衰老与认知的关系,以及在开普敦青少年抗逆转录病毒队列研究(CTAAC)中招募的PHU和健康对照者的全脑结构变化。IlluminaEPIC阵列用于在基线和36个月随访时从60名PHIV1+青少年和36名年龄匹配的9-12岁对照中产生血液DNA甲基化数据。表观遗传时钟软件估算了表观遗传年龄加速的两种度量:两个时间点的外在表观遗传加速衰老(EEAA)和年龄加速差(AAD)。在后续行动中,每个参与者都完成了神经心理学测试,结构磁共振成像,和扩散张量成像。在后续行动中,pHIV感染仍然与EEAA和AAD增加相关。加速的表观遗传衰老与病毒载量呈正相关,与CD4比率呈负相关。EEAA与全脑灰质体积和全脑白质完整性的改变呈正相关。PAD和EEAA与PHV组的认知功能无关。表观遗传衰老的测量,在DNA甲基化模式中检测到,在36个月的时间里,艾滋病毒+青少年保持增加。表观遗传衰老指标之间的关联,病毒生物标志物,在36个月的随访中,大脑微观和宏观结构的改变也持续存在。进一步的研究应该确定表观遗传年龄加速是否与晚年大脑改变导致的认知功能变化有关。
    We have previously shown accelerated ageing in adolescents perinatally infected with HIV (PHIV +), based on discrepancies between epigenetic and chronological age. The current study examines follow-up longitudinal patterns of epigenetic ageing and the association of epigenetic ageing with cognition as well as whole brain structure changes in PHIV + and healthy controls enrolled in the Cape Town Adolescent Antiretroviral Cohort Study (CTAAC). The Illumina EPIC array was used to generate blood DNA methylation data from 60 PHIV + adolescents and 36 age-matched controls aged 9-12 years old at baseline and again at a 36-month follow-up. Epigenetic clock software estimated two measures of epigenetic age acceleration: extrinsic epigenetic accelerated ageing (EEAA) and age acceleration difference (AAD) at both time points. At follow-up, each participant completed neuropsychological testing, structural magnetic resonance imaging, and diffusion tensor imaging. At follow-up, PHIV infection remains associated with increased EEAA and AAD. Accelerated epigenetic ageing remained positively associated with viral load and negatively associated with CD4 ratio. EEAA was positively associated with whole brain grey matter volume and alterations in whole brain white matter integrity. AAD and EEAA were not associated with cognitive function within the PHIV + group. Measures of epigenetic ageing, as detected in DNA methylation patterns, remain increased in PHIV + adolescents across a 36-month period. Associations between epigenetic ageing measures, viral biomarkers, and alterations in brain micro- and macrostructure also persist at 36-month follow-up. Further study should determine if epigenetic age acceleration is associated with cognitive functional changes due to brain alterations in later life.

    在高患病率环境中,感染艾滋病毒的年轻女性的宫颈癌负担和前兆病变的患病率是未知的。在资源有限的环境中,目前的宫颈癌筛查指南通常排除青少年和年轻女性。在观察了患有围产期HIV的年轻女性中的两例晚期宫颈癌病例后,博茨瓦纳建立了一个试点筛查方案。
    为了比较患有围产期HIV的年轻女性与30-49岁女性的宫颈异常患病率,无论艾滋病毒状况如何。
    我们对30-49岁的妇女进行了横断面研究,这些妇女通过博茨瓦纳公共部门计划通过乙酸筛查进行了目视检查,和青少年(15-24岁)围产期感染艾滋病毒,在2016年至2018年之间的单个推荐站点。我们描述了每组中宫颈异常的患病率以及粗患病率。
    30-49岁女性宫颈异常的患病率为10.9%(95%置信区间[CI]:10.4,11.4),青年为10.1%(95%CI:4.7,18.3)。粗患病率为1.07(95%CI:0.58,2.01)。
    在HIV和宫颈癌高发环境中,应考虑将感染HIV的青年纳入宫颈癌筛查服务。
    UNASSIGNED: Cervical cancer burden and prevalence of precursor lesions is unknown among young women living with HIV in high prevalence settings. Current cervical cancer screening guidelines in resource-limited settings with high HIV prevalence typically exclude adolescents and young women. After observing two cases of advanced cervical cancer among young women with perinatally acquired HIV, a pilot screening programme was established in Botswana.
    UNASSIGNED: To compare the prevalence of cervical abnormalities in young women with perinatally acquired HIV with women aged 30-49 years, regardless of HIV status.
    UNASSIGNED: We conducted a cross-sectional study of 30-49-year-old women who had visual inspection with acetic acid screening through the Botswana public sector programme, and youth (aged 15-24 years) with perinatally acquired HIV, at a single referral site between 2016 and 2018. We describe the prevalence of cervical abnormalities in each group as well as the crude prevalence ratio.
    UNASSIGNED: The prevalence of cervical abnormalities in women 30-49 years of age was 10.9% (95% confidence interval [CI]: 10.4, 11.4), and 10.1% (95% CI: 4.7, 18.3) for youth. The crude prevalence ratio was 1.07 (95% CI: 0.58, 2.01).
    UNASSIGNED: Inclusion of youth living with HIV in cervical cancer screening services should be considered in settings with a high prevalence of HIV and cervical cancer.
