Ethical Issues in Genetics and Infectious Diseases Research: An Interdisciplinary Expert Review.

PURPOSE: Research in genetics and infectious diseases (ID) presents novel configurations of ethical, legal, and social issues (ELSIs) related to the intersection of genetics with public health regulations and the control of transmissible diseases. Such research includes work both in pathogen genetics and on the ways that human genetics affect responses to ID. This paper identifies and systematizes the unique issues at this intersection, based on an interdisciplinary expert review. BASIC PROCEDURES: This paper presents results of a formal issue-spotting exercise among twenty experts in public health, law and genomics, biobanking, genetic epidemiology, ID medicine and public health, philosophy, ethics and ID, ethics and genomics, and law and ID. The focus of the exercise was on the collection, storage, and sharing of genetic information relating to ID. MAIN FINDINGS: The issue-spotting exercise highlighted the following ELSIs: risks in reporting to government authorities, return of individual research results, and resource allocation - each taking on specific configurations based on the balance between public health and individual privacy/protection. PRINCIPAL CONCLUSIONS: The public health implications of interactions between genomics and ID frame considerations for equity and justice. In the context of the COVID-19 pandemic, these issues are especially pressing.

Levels of Angiotensin-Converting Enzyme and Apolipoproteins Are Associated with Alzheimer's Disease and Cardiovascular Diseases.

Angiotensin-converting enzyme-1 (ACE1) and apolipoproteins (APOs) may play important roles in the development of Alzheimer's disease (AD) and cardiovascular diseases (CVDs). This study aimed to examine the associations of AD, CVD, and endocrine-metabolic diseases (EMDs) with the levels of ACE1 and 9 APO proteins (ApoAI, ApoAII, ApoAIV, ApoB, ApoCI, ApoCIII, ApoD, ApoE, and ApoH). Non-Hispanic white individuals including 109 patients with AD, 356 mild cognitive impairment (MCI), 373 CVD, 198 EMD and controls were selected from the Alzheimer's Disease Neuroimaging Initiative (ADNI) dataset. Multivariable general linear model (GLM) was used to examine the associations. ApoE ε4 allele was associated with AD, as well as ApoAIV, ApoB and ApoE proteins, but not associated with CVD and EMD. Both AD and CVD were associated with levels of ACE1, ApoB, and ApoH proteins. AD, MCI and EMD were associated with levels of ACE1, ApoAII, and ApoE proteins. This is the first study to report associations of ACE1 and several APO proteins with AD, MCI, CVD and EMD, respectively, including upregulated and downregulated protein levels. In conclusion, as specific or shared biomarkers, the levels of ACE1 and APO proteins are implicated for AD, CVD, EMD and ApoE ε4 allele. Further studies are required for validation to establish reliable biomarkers for these health conditions.

HIV DNA Is Frequently Present within Pathologic Tissues Evaluated at Autopsy from Combined Antiretroviral Therapy-Treated Patients with Undetectable Viral Loads.

UNLABELLED: HIV infection treatment strategies have historically defined effectiveness through measuring patient plasma HIV RNA. While combined antiretroviral therapy (cART) can reduce plasma viral load (pVL) to undetectable levels, the degree that HIV is eliminated from other anatomical sites remains unclear. We investigated the HIV DNA levels in 229 varied autopsy tissues from 20 HIV-positive (HIV(+)) cART-treated study participants with low or undetectable plasma VL and cerebrospinal fluid (CSF) VL prior to death who were enrolled in the National Neurological AIDS Bank (NNAB) longitudinal study and autopsy cohort. Extensive medical histories were obtained for each participant. Autopsy specimens, including at least six brain and nonbrain tissues per participant, were reviewed by study pathologists. HIV DNA, measured in tissues by quantitative and droplet digital PCR, was identified in 48/87 brain tissues and 82/142 nonbrain tissues at levels >200 HIV copies/million cell equivalents. No participant was found to be completely free of tissue HIV. Parallel sequencing studies from some tissues recovered intact HIV DNA and RNA. Abnormal histological findings were identified in all participants, especially in brain, spleen, lung, lymph node, liver, aorta, and kidney. All brain tissues demonstrated some degree of pathology. Ninety-five percent of participants had some degree of atherosclerosis, and 75% of participants died with cancer. This study assists in characterizing the anatomical locations of HIV, in particular, macrophage-rich tissues, such as the central nervous system (CNS) and testis. Additional studies are needed to determine if the HIV recovered from tissues promotes the pathogenesis of inflammatory diseases, such as HIV-associated neurocognitive disorders, cancer, and atherosclerosis. IMPORTANCE: It is well-known that combined antiretroviral therapy (cART) can reduce plasma HIV to undetectable levels; however, cART cannot completely clear HIV infection. An ongoing question is, "Where is HIV hiding?" A well-studied HIV reservoir is "resting" T cells, which can be isolated from blood products and succumb to cART once activated. Less-studied reservoirs are anatomical tissue samples, which have unknown cART penetration, contain a comparably diverse spectrum of potentially HIV-infected immune cells, and are important since <2% of body lymphocytes actually reside in blood. We examined 229 varied autopsy specimens from 20 HIV(+) participants who died while on cART and identified that >50% of tissues were HIV infected. Additionally, we identified considerable pathology in participants' tissues, especially in brain, spleen, lung, lymph node, liver, aorta, and kidney. This study substantiates that tissue-associated HIV is present despite cART and can inform future studies into HIV persistence.

Avoiding Same-Day Cystoscopy Cancellations by Veterans: Nurse-Led Education Improved Efficiency for Cystoscopy in VA Urology Clinics.

Same-day cancellation of outpatient cystoscopy was recognized as a growing problem in a New Mexico Veterans Administration regional urology clinic. A multidisciplinary team initiated a performance improvement project using the VA-TAMMCS method to address the problem. The resulting changes in patient education significantly reduced cystoscopy cancellations and improved overall patient satisfaction.

Accuracy of harm scores entered into an event reporting system.

This quality improvement project evaluated the accuracy of harm scores entered into an event reporting system by inpatient nursing staff at a National Cancer Institute-designated comprehensive cancer center. Nurses scored 10 safety scenarios using 2 versions of the Agency for Healthcare Research and Quality scale to determine interrater reliability. Results indicated inconsistency in the way nurses scored the scenarios, suggesting that the event reporting system may not accurately portray the severity of harm in patient safety events. Nurse executives can use this information to guide the development and implementation of incident reporting systems.

The AIDS and Cancer Specimen Resource.

The AIDS and Cancer Specimen Resource (ACSR) is a cooperative agreement among the United States National Cancer Institute (NCI) (Office of the Director, Office of HIV and AIDS Malignancy (OHAM)) and regional US consortia, University of California, San Francisco (West Coast), George Washington University (East Coast), and The Ohio State University (Mid-Region). The ACSR's main objective is to collect, preserve, and disperse HIV-related tissues and biologic fluids along with clinical data to qualified investigators with a focus on HIV/AIDS-related malignancies. The ACSR biorepository has more than 265,000 human HIV-positive and control samples available from 39 processing types, 16 specimen types, and 52 anatomical site types. These HIV-infected biological fluids and tissues are made available to funded approved investigators at no fee. Technical support such as HIV DNA identification in tissues and tissue microarray (TMA) blocks are available to assist approved investigators. Research needs may be filled through ACSR cooperative arrangements when not met by currently banked material. Those participating with the ACSR are expected to share their research findings with the scientific community. Some 117 abstract/poster and podium reports at national and international scientific meetings and 94 publications have been contributed to the scientific literature (as of 2010). Investigators can browse the ACSR Internet site at http://acsr.ucsf.edu for biospecimens to support their scientific initiatives, including basic, translational, biomarker discovery, and molecular epidemiology studies.
