Increased resilience has been consistently linked to improved mental and physical health outcomes. Because individuals with HIV have a longer life expectancy than ever before, it is imperative to identify mechanisms to promote resilience in this population. Physical activity has significant potential to strengthen resilience and improve overall well-being in individuals with HIV. The goal of this study was to investigate whether increased physical activity is positively associated with increased individual-level psychosocial resilience, and whether this association varied by HIV status. Data for this analysis were obtained from the Multicenter AIDS Cohort Study (MACS), a longitudinal observational cohort study following men living with and without HIV in the United States. Specifically, cross-sectional data collected between October 2016 and March 2017 from 1118 MACS participants enrolled in the Understanding Patterns of Healthy Aging Among Men Who Have Sex With Men sub-study were used. Odds ratios were determined using logistic regression to examine the association of physical activity with psychosocial resilience (measured using the 14-item Resilience Scale). Among all MACS participants enrolled in the sub-study, both sufficient physical activity and health-enhancing physical activity were positively associated with high resiliency (odds ratio, 2.20 [95% CI, 1.36-3.56] and odds ratio, 3.72 [95% CI, 2.30-6.03], respectively). Among the participants with HIV, only health-enhancing physical activity was positively associated with high resiliency (odds ratio, 3.07 [95% CI, 1.54-6.14]). At the level of individual patient care, physical activity has significant potential to improve health outcomes and strengthen resilience in individuals living with HIV.
增强的适应力一直与改善的精神和身体健康结果有关。由于艾滋病毒感染者的预期寿命比以往任何时候都要长,因此必须确定促进这一人群恢复能力的机制。身体活动在增强艾滋病毒感染者的复原力和改善整体福祉方面具有巨大潜力。本研究的目的是调查增加的身体活动是否与增加的个人层面的社会心理恢复能力呈正相关,以及这种关联是否因艾滋病毒感染状况而异。该分析的数据来自多中心艾滋病队列研究(MACS),这是一项纵向观察队列研究,追踪美国感染和未感染艾滋病毒的男性。具体而言,使用了2016年10月至2017年3月从1118名参加男男性行为者健康衰老理解模式亚研究的MACS参与者中收集的横断面数据。使用逻辑回归来确定优势比,以检验体育活动与心理社会恢复力的关系(使用14项恢复力量表测量)。在所有参加子研究的MACS参与者中,充分的体力活动和促进健康的体力活动与高弹性呈正相关(比值比分别为2.20 [95% CI, 1.36-3.56]和3.72 [95% CI, 2.30-6.03])。在艾滋病毒携带者中,只有促进健康的体育活动与高恢复力呈正相关(优势比为3.07 [95% CI, 1.54-6.14])。在个体患者护理层面,身体活动在改善艾滋病毒感染者的健康结果和增强复原力方面具有巨大潜力。

Negative aging perceptions have been shown to influence one’s health care–seeking behaviors; this relationship has not been studied among middle-aged and aging adults living with HIV. The current study uses data from the Multicenter AIDS Cohort Study (MACS) to investigate the association between subjective age and health care avoidance. To examine the hypothesis that adults living with HIV who perceive themselves as older, after adjustment for covariates, would be more likely to avoid care than their HIV-negative counterparts who perceive themselves as older. The MACS is a prospective study of more than 7000 sexual minority men living with and without HIV from 4 metropolitan US areas. The Understanding Patterns of Healthy Aging in Men Who Have Sex With Men sub-study of the MACS was conducted from April 2016 to March 2019. Current analyses use cross-sectional data on 1118 participants from this sub-study from October 2016 to March 2017. Logistic regression was used to produce odds ratios and 95% CIs examining the association between subjective age and health care avoidance. Covariates included age, HIV status, race and ethnicity, education, and comorbid conditions. Further analyses were conducted among persons living with HIV, which included CD4 counts and viral load detection as covariates. In the full sample and sample of people living with HIV, after adjustment for covariates, there was a positive association between older subjective age and health care avoidance and a negative association between younger subjective age and health care avoidance, albeit both not statistically significant. Living with HIV was positively associated with health care avoidance, but not statistically significant. Future studies with larger sample sizes are needed to elucidate the significance of subjective age and health care avoidance. Aside from the pivotal role of health care avoidance, the field of HIV and aging may benefit from identifying other psychological, physiological, and behavioral mechanisms by which perceptions of aging influence health.
消极的衰老观念已被证明会影响一个人的就医行为;这种关系尚未在感染艾滋病毒的中老年成年人中得到研究。目前的研究使用来自多中心艾滋病队列研究(MACS)的数据来调查主观年龄与卫生保健回避之间的关系。为了检验这样一个假设,即认为自己年龄较大的艾滋病毒感染者,在调整协变量后,比认为自己年龄较大的艾滋病毒阴性患者更有可能避免护理。MACS是一项前瞻性研究,研究对象是来自美国4个大都市地区的7000多名携带或未携带艾滋病毒的性少数男性。MACS的“男男性行为者对健康衰老的认识模式”亚研究于2016年4月至2019年3月进行。目前的分析使用了2016年10月至2017年3月期间该子研究中1118名参与者的横断面数据。采用Logistic回归产生比值比和95% ci,检验主观年龄与保健回避之间的关系。协变量包括年龄、艾滋病毒状况、种族和民族、教育程度和合并症。在艾滋病毒感染者中进行了进一步的分析,其中包括CD4计数和病毒载量检测作为协变量。在全样本和艾滋病毒感染者样本中,调整协变量后,老年人主观年龄与逃避医疗保健之间存在正相关关系,而年轻人主观年龄与逃避医疗保健之间存在负相关关系,尽管两者都没有统计学意义。艾滋病毒携带者与逃避医疗保健呈正相关,但没有统计学意义。未来需要更大样本量的研究来阐明主观年龄与保健回避的意义。除了医疗保健回避的关键作用外,艾滋病毒和衰老领域可能受益于确定其他心理,生理和行为机制,通过这些机制对衰老的看法影响健康。

Understanding perceptions of uncertainty among parents of children with chronic conditions—and health care providers’ opportunities to help parents effectively cope—is limited by existing measures. To develop a novel, outcomes-oriented scale to measure parental perceptions of uncertainties about the health of a child. Informed by existing literature and interviews with parents, items were generated to capture disease-centered uncertainties (about diagnosis, prognosis, treatment) and patient-centered uncertainties (about familial, reproductive, social, and existential implications). After pilot testing, the Parental Uncertainty About a Child’s Health Scale (PUCHS) was administered in 3 studies assessing parental uncertainty in the context of caring for a child with an undiagnosed medical condition. Data from 2 studies (n = 149) were used to refine the hypothesized measurement model, and data from a third study (n = 417) were used to conduct a confirmatory factor analysis to determine the fit of the resulting measurement model. A 4-factor model (diagnostic, therapeutic, familial, social) satisfied overall model fit statistics and structural validity as indicated by standardized loadings, reliability, and variance extracted for each of the constructs. Additionally, each of the constructs satisfied convergent and discriminant validity. These findings across multiple samples in varying contexts suggest that the model demonstrates configural invariance across applications. As a valid, reliable measure of parental uncertainties about children with chronic undiagnosed medical conditions, the PUCHS will advance understanding and thereby inform development of interventions to manage uncertainties. Communication of these uncertainties and their effective management are fundamental components of patient-centered care.
了解慢性病儿童父母对不确定性的看法,以及卫生保健提供者帮助父母有效应对的机会,受到现有措施的限制。开发一种新颖的、以结果为导向的量表来衡量父母对孩子健康不确定性的看法。根据现有文献和对父母的访谈,生成了以疾病为中心的不确定性(关于诊断、预后、治疗)和以患者为中心的不确定性(关于家庭、生殖、社会和存在的影响)。在试点测试后,在3项研究中使用父母对儿童健康的不确定性量表(PUCHS)来评估父母在照顾患有未确诊疾病的儿童时的不确定性。我们使用2项研究(n = 149)的数据来完善假设的测量模型,并使用第三项研究(n = 417)的数据进行验证性因子分析,以确定所得测量模型的拟合性。一个四因素模型(诊断、治疗、家庭、社会)满足整体模型拟合统计和结构效度,如标准化负荷、信度和每个结构提取的方差所示。此外,每个构念都满足收敛效度和区分效度。这些发现跨越了不同上下文中的多个样本,表明该模型展示了跨应用程序的配置不变性。作为父母对患有慢性未确诊疾病的儿童的不确定性的有效、可靠的衡量标准,PUCHS将促进理解,从而为制定管理不确定性的干预措施提供信息。这些不确定因素的沟通及其有效管理是以患者为中心的护理的基本组成部分。

The Physiological Mechanisms of Triple Negative Breast Cancer in African American Women 非裔美国妇女三阴性乳腺癌的生理机制
Pub Date : 2023-01-04 DOI: 10.52504/001c.57753

Breast cancer is one of the leading causes of cancer-related mortality among women. Multiple subtypes exist for tumor biology, but triple-negative breast cancer (TNBC) lacks expression of the estrogen receptor, progesterone receptor, and human epidermal growth factor. TNBC accounts for 20% of breast cancers and is one of the most aggressive subtypes associated with an earlier age susceptibility, racial and ethnic differences, and limited targeted therapies. African American women bear a disproportionate burden in oncology-related health disparities. This population of women is diagnosed at later stages often with regional to distant metastases, high tumor grades, aberrant sequence mutations, treatment delays, and decreased disease-free survival. This review explores the multifactorial nature of this health disparity by addressing the physiological mechanisms, socioeconomic factors, ancestral differences, and challenges associated with diagnosis and treatment methods in the era of precision medicine.
乳腺癌是妇女癌症相关死亡的主要原因之一。肿瘤生物学中存在多种亚型,但三阴性乳腺癌(TNBC)缺乏雌激素受体、孕激素受体和人表皮生长因子的表达。TNBC占乳腺癌的20%,是最具侵袭性的亚型之一,与早期的年龄易感性、种族和民族差异以及有限的靶向治疗有关。非裔美国妇女在与肿瘤相关的健康差异中承担着不成比例的负担。这类妇女在晚期被诊断为区域到远处转移,肿瘤分级高,序列突变异常,治疗延迟,无病生存率降低。本文从生理机制、社会经济因素、祖先差异以及精准医学时代诊断和治疗方法的挑战等方面探讨了这种健康差异的多因素本质。

Myocardial infarction (MI) poses a significant burden to both patients and the health care system. The irreversible loss of functional cardiomyocytes due to ischemia threatens both patients’ immediate survival and quality of life over their lifespan. Stem cell therapy has been proposed as a solution to salvage cardiac contractility through the regeneration of cardiomyocytes, and bone marrow–derived stem cells (BMSc) are among the category of stem cells most extensively studied. Despite the promising theoretical potential of BMSc in tissue regeneration, several key aspects remain to be better understood to enable large-scale clinical application, including safety and efficacy. Our current work in synthesizing and evaluating both preclinical and clinical studies using stem cell applications in acute MI has demonstrated that BMSc transplantation is a safe therapy for MI. Although this therapy’s efficacy is not consistently proven, we have significantly improved our understanding of factors contributing to its success, such as the stem cell type, patients’ baseline left ventricular ejection fraction, individual hemodynamic factors, and differential expressions of specific genes. In future investigations, researchers should focus on the cellular and individual attributes of BMSc treatment to achieve maximal efficacy and outcomes for patients receiving this therapy after acute MI.
心肌梗死(MI)给患者和卫生保健系统带来了巨大的负担。心肌缺血导致的功能性心肌细胞不可逆转的丧失威胁着患者的直接生存和生命质量。干细胞疗法被认为是通过心肌细胞再生来挽救心脏收缩能力的一种解决方案,而骨髓源性干细胞(BMSc)是研究最广泛的干细胞之一。尽管BMSc在组织再生方面有很大的理论潜力,但为了实现大规模的临床应用,包括安全性和有效性,几个关键方面仍有待更好的理解。我们目前在综合和评估干细胞在急性心肌梗死中的临床前和临床研究方面的工作表明,骨髓间充质干细胞移植是一种安全的心肌梗死治疗方法。尽管这种治疗的疗效尚未得到一致的证明,但我们已经显著提高了对其成功的因素的理解,如干细胞类型、患者基线左心室射血分数、个体血流动力学因素、以及特定基因的差异表达。在未来的研究中,研究人员应该关注骨髓间充质干细胞治疗的细胞和个体属性,以使急性心肌梗死后接受这种治疗的患者获得最大的疗效和结果。

Outbreaks of Vector-borne Infectious Disease Following a Natural Disaster 自然灾害后媒传传染病的爆发
Pub Date : 2022-12-21 DOI: 10.52504/001c.38768
Norma Quintanilla
Over the past century, global disaster deaths have averaged approximately 45,000 people annually. Vector-borne pathogens are susceptible to climatic conditions influencing vector survival, gonotrophic cycle, and transmission efficiency in human hosts. However, the literature has not collectively analyzed the relationship between natural disasters and vector-borne disease (VBD) outbreaks over decades. This literature review identifies and examines published papers documenting VBD outbreaks associated with natural disasters. Additionally, information was gathered about the kinds of natural disasters commonly associated with VBD outbreaks and which diseases typically occur post- disasters. A literature review was performed using two search strategies with terms for natural disasters and vector-borne infectious diseases as identified in the title, keywords, or abstract. Observational studies and systematic review papers were screened on the occurrence of a VBD post-disaster. A total of 30 studies were captured. Eight disaster types were captured: flood, hurricane, tropical cyclone, typhoon, tsunami, drought, monsoon, and earthquake. Floods (n=21), hurricanes (n=20), tsunamis (n=8), and drought (n=8) account for the top four disaster events commonly associated with VBDs. Of the VBDs identified, malaria outbreaks were identified in 16 papers, while dengue outbreaks were captured in 11. The literature reveals a predominance of floods, malaria and dengue. While there is increasing acknowledgment that disasters can lead to outbreaks of VBDs, there is limited research and consistent data available. Future research should rely on well-defined, consistent case detection and enrollment procedures, preferably at various lag periods following a disaster event.
在过去一个世纪中,全球每年平均因灾害死亡的人数约为45 000人。媒介传播的病原体容易受到影响媒介生存、淋养循环和人类宿主传播效率的气候条件的影响。然而,几十年来,文献并没有集体分析自然灾害与病媒传播疾病(VBD)暴发之间的关系。本文献综述确定并检查了记录与自然灾害相关的VBD暴发的已发表论文。此外,还收集了通常与VBD暴发有关的各种自然灾害以及灾后通常发生的疾病的信息。使用两种搜索策略对自然灾害和媒介传播的传染病进行文献综述,这些术语在标题、关键词或摘要中确定。对灾后发生VBD的观察性研究和系统评价论文进行了筛选。总共收录了30项研究。捕获了八种灾害类型:洪水、飓风、热带气旋、台风、海啸、干旱、季风和地震。洪水(n=21)、飓风(n=20)、海啸(n=8)和干旱(n=8)是通常与vbd相关的前四大灾害事件。在确定的野生生物多样性中,16篇论文确定了疟疾暴发,11篇论文记录了登革热暴发。文献显示洪水、疟疾和登革热占主导地位。虽然人们越来越认识到灾害可能导致生物多样性疾病的爆发,但现有的研究和一致的数据有限。未来的研究应依赖于明确的、一致的病例发现和登记程序,最好是在灾难事件后的不同滞后期。

Vector-borne pathogens are susceptible to climatic conditions influencing vector survival, gonotrophic cycle, and transmission efficiency in human hosts. However, the literature has not collectively analyzed the relationship between natural disasters and vector-borne disease (VBD) outbreaks over decades. This literature review identifies and examines published papers documenting VBD outbreaks associated with natural disasters. Additionally, information was gathered about the kinds of natural disasters commonly associated with VBD outbreaks and which diseases typically occur post- disasters. A literature review was performed using two search strategies with terms for natural disasters and vector-borne infectious diseases as identified in the title, keywords, or abstract. Observational studies and systematic review papers were screened on the occurrence of a VBD post-disaster. A total of 30 studies were captured. Eight disaster types were captured: flood, hurricane, tropical cyclone, typhoon, tsunami, drought, monsoon, and earthquake. Floods (n=21), hurricanes (n=20), tsunamis (n=8), and drought (n=8) account for the top four disaster events commonly associated with VBDs. Of the VBDs identified, malaria outbreaks were identified in 16 papers, while dengue outbreaks were captured in 11. The literature reveals a predominance of floods, malaria and dengue. While there is increasing acknowledgment that disasters can lead to outbreaks of VBDs, there is limited research and consistent data available. Future research should rely on well-defined, consistent case detection and enrollment procedures, preferably at various lag periods following a disaster event.","PeriodicalId":340325,"journal":{"name":"Georgetown Medical Review","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132265630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Family planning is critical to the sexual and reproductive health of all patients. For transgender individuals, using gender-preferred modalities for conception and prevention can minimize gender incongruence and dysphoria. Currently, the literature describes several pregnancy options including natural conception, gamete cryopreservation, in vitro fertilization, and uterine transplantation. Prevention methods remain similar to those for cisgender patients such as oral contraception, intrauterine devices, condoms, and various surgical procedures. However, great emphasis lies on choosing a method that best supports the chosen gender identity of the patient. This review supports oocyte and sperm cryopreservation as the preferred method for pregnancy and finds consensus with the literature that there is no best method for prevention. As such, physicians should prioritize early discussions with patients and work closely to use modalities that fit each patient’s needs and expectations. As the body of literature on LGBTQ+ health continues to grow, this review will help to expand the knowledge around family planning for transgender patients.
计划生育对所有患者的性健康和生殖健康至关重要。对于跨性别者,使用性别偏好的方式受孕和预防可以最大限度地减少性别不一致和不安。目前,文献描述了几种妊娠选择,包括自然受孕、配子冷冻保存、体外受精和子宫移植。预防方法与治疗顺性患者的方法类似,如口服避孕药、宫内节育器、避孕套和各种外科手术。然而,重点在于选择一种最能支持患者所选择的性别认同的方法。本综述支持卵母细胞和精子冷冻保存作为妊娠的首选方法,并与文献一致认为没有最好的预防方法。因此,医生应该优先与患者进行早期讨论,并密切合作,使用适合每位患者需求和期望的治疗方式。随着关于LGBTQ+健康的文献不断增加,本综述将有助于扩大跨性别患者的计划生育知识。
