Reflex Human Immunodeficiency Virus (HIV) Type 1 RNA Testing Enables Timely Differentiation of False-Positive Results From Acute HIV Infection.

Accurate, timely human immunodeficiency virus (HIV) diagnosis is critical. Routine HIV screening program data were examined before and after reflex HIV type 1 RNA testing. Reflex testing facilitated confirmation of reactive HIV screening assays (as true or false positives) (odds ratio, 23.7 [95% confidence interval, 6.7-83.4]; P < .0001), improving detection of acute HIV and reducing unconfirmed discordant results.

"Even if I'm undetectable, I just feel like I would die": a qualitative study to understand the psychological and socioeconomic impacts of the COVID-19 pandemic on women living with HIV (WLWH) in Chicago, IL.

BACKGROUND: The COVID-19 pandemic has affected the health and well-being of people worldwide, yet few studies have qualitatively examined its cumulative effects on ciswomen living with HIV (WLWH). We aimed to explore how the pandemic has impacted WLWH, including challenges related to HIV care, employment, finances, and childcare. We also investigated how HIV status and different psychosocial stressors affected their mental health. METHODS: We performed 25 semi-structured qualitative interviews with WLWH regarding the ways in which COVID-19 impacted their social determinants of health and physical well-being during the pandemic. 19 WLWH who received care at the University of Chicago Medicine (UCM) and 6 women who received care at Howard Brown Health, a federally qualified health center (FQHC) in Chicago, were interviewed remotely from June 2020 to April 2021. All interviews were audio recorded and transcribed. Interviews were thematically analyzed for commonalities regarding HIV-specific and general experiences of WLWH during the pandemic. RESULTS: The majority of participants reported COVID-19 impacted their HIV care, such as appointment cancellations and difficulties adhering to antiretroviral therapy. In addition to HIV care obstacles, almost all participants described perceived heightened vulnerability to or fear of COVID-19. The pandemic also affected the socioeconomic well-being of participants, with reported financial strains and employment disruptions. Some mothers took on additional childcare responsibilities, such as homeschooling. Increased mental health concerns and negative psychological effects from the social isolation associated with the pandemic were also experienced by most participants. CONCLUSIONS: We gained invaluable insight into how WLWH were challenged by and adapted to the COVID-19 pandemic, including its destabilizing effects on their HIV care and mental health. Women described how they undertook additional childcare responsibilities during the pandemic and how their HIV status compounded their concerns (e.g., perceived heightened vulnerability to COVID-19). Strategies to better support WLWH in maintaining their overall health throughout the pandemic include childcare assistance, access to affordable mental health services, support groups, and education from HIV care providers. These findings have significant implications for examining future health crises through the perspective of potential gender inequalities.

"When you have an immune disease like HIV and there is a pandemic, you still have to pay your bills": COVID-19-related challenges among people living with HIV and lessons for care delivery.

COVID-19 has disrupted routine medical care and increased psychosocial and economic stressors on a global scale, yet the full impact on people living with HIV (PLWH) and the HIV continuum of care remains unknown. As the pandemic continues to pose a significant threat to PLWH and their care, this research qualitatively aimed to elicit COVID-19-related challenges and perspectives of PLWH during the early phase of the pandemic and to identify lessons learned and impactful strategies for facilitating HIV care. We recruited 32 PLWH who receive care at a large academic medical center for semi-structured remote interviews to assess psychological/structural stressors experienced during the pandemic and to discern strategies for improving care. Most participants identified as Black (91%) and heterosexual (56%). Overall, PLWH reported exacerbated mental health stressors (e.g., anxiety, depression, substance use). Most participants cited no issues with antiretroviral therapy (ART) adherence or retention in care, yet five participants reported appointment cancellations or physician inaccessibility. Participants provided specific feedback for facilitating continued engagement in care during the pandemic, including telemedicine and education/patient empowerment. By seeking participant-provided solutions, this study centered on PLWH's experiences and emphasized proactive HIV care strategies for prioritizing patient empowerment and healthcare adaptability during a rapidly evolving pandemic.

"That same stigma...that same hatred and negativity:" a qualitative study to understand stigma and medical mistrust experienced by people living with HIV diagnosed with COVID-19.

BACKGROUND: The COVID-19 and HIV epidemics have exacerbated existing inequities among vulnerable groups and severely impacted communities of color. People living with HIV (PLWH), who may already face stigma or discrimination, are at risk of experiencing further stigma as a result of COVID-19, which can result in medical mistrust. METHODS: We performed qualitative interviews between June and August 2020 among 32 PLWH, including 10 individuals diagnosed with COVID-19. A majority of participants perceived themselves as having an increased risk of contracting COVID-19 due to their HIV status. RESULTS: Of those who tested positive for COVID-19, the majority regarded their HIV diagnosis as having a more profound impact on their lives but found similarities between COVID-19 stigma and HIV-related stigma. Many participants also expressed mistrust. CONCLUSIONS: These results can be used to better understand the perspectives of PLWH during the COVID-19 pandemic and have important implications for potential COVID-19 vaccine hesitancy and future health crises.

Inside SMP proteomics: six years German Human Brain Proteome Project (HBPP) - a summary.

In 2001, the German Federal Ministry of Education and Research (BMBF) initiated the National Genome Research Network (NGFN; www.ngfn.de) as a nation-wide multidisciplinary networking platform aiming at the analysis of common human diseases and aging. Within the NGFN the Human Brain Proteome Project (HBPP; www.smp-proteomics.de) focuses on the analysis of the human brain in health and disease. The concept is based on two consecutive steps: (i) Elaborating and establishing the necessary technology platforms. (ii) Application of the established technologies for research in Alzheimer's disease and Parkinson's disease. In the first funding period, HBPP1, running from 2001 to 2004, necessary technologies were established and optimized. In HBPP2, which started 2004 and will end in May 2008, the developed technologies are used for large-scale experiments, offering new links for disease related research and therapies. The following overview describes structure, aims and outcome of this unique German Brain Proteome Project.

International Symposium on High Performance Proteomics 2007: a contribution to Proteomics May 14-16, 2007 Dortmund, Germany.

The symposium High Performance Proteomics was held in Dortmund on May 14-16, 2007, to celebrate the opening of the Zentrum für Angewandte Proteomik as well as the 6(th) anniversary of the German Human Brain Proteome Project. It offered an outstanding opportunity to obtain a broad overview about all fields of proteomics and related fields, combining the expertise of biochemists, physicians, bioinformatics, mathematicians and other researchers in Life Sciences. The main topics were the presentation of state-of-the-art proteomics technologies as well as possible transfer models for industrial applications. An accompanying industrial exhibition, as well as a discussion panel, offered the possibility to get in contact with colleagues and potential industrial partners. A visit to the former colliery Zeche Zollern and the social event at the Harenberg City-Center with an excellent view around Dortmund also left time for further communication between the more than 200 attendees.

Proteomics for everyday use: activities of the HUPO Brain Proteome Project during the 5th HUPO World Congress.

Long Beach hosted this year's annual congress of the Human Proteome Organisation (HUPO). In addition to the numerous sessions, talks and poster presentations organized by HUPO itself, several events were arranged by the HUPO initiatives. The Brain Proteome Project (HUPO BPP) was very active, initiating three pre-congress workshops: (i) the kick-off meeting of the EU-funded ProDaC consortium (Proteomics Data Collection) that is aiming at the bioinformatics Standardization in the proteomics field; (ii) the workshop "Standardization Issues in Proteomics: Perspectives from Vendors" giving an overview about the lessons learned by proteomics industrial partners; (iii) the 6th HUPO BPP Workshop "New Proteomics Approaches for further HUPO BPP Studies" offering new concepts for brain-related proteomics studies.

Pilot study of the Human Proteome Organisation Brain Proteome Project: applying different 2-DE techniques to monitor proteomic changes during murine brain development.

The Human Proteome Organisation Brain Proteome Project aims at coordinating neuroproteomic activities with respect to analysis of development, aging, and evolution in human and mice and at analysing normal aging processes as well as neurodegenerative diseases. Our group participated in the mouse pilot study of this project using two different 2-DE systems, to find out the optimal conditions for comprehensive gel-based differential proteome analysis. Besides the assessment of the best methodical conditions the question of "How many biological replicate analyses have to be performed to get reliable statistically validated results?" was addressed. In total 420 differences were detected in all analyses. Both 2-DE methods were found to be suitable for comprehensive differential proteome analysis. Nevertheless, each of the methods showed substantial advantages and disadvantages resulting in the fact that modification of both systems is essential. From our results we can draw the conclusions that for the future optimal quantitative differential gel-based brain proteome analyses the sample preparation has to be slightly changed, the resolution of the first as well as the second dimension has to be advanced, the number of experiments has to be increased and that the 2D-DIGE system should be applied.

Automated reprocessing pipeline for searching heterogeneous mass spectrometric data of the HUPO Brain Proteome Project pilot phase.

The newly available techniques for sensitive proteome analysis and the resulting amount of data require a new bioinformatics focus on automatic methods for spectrum reprocessing and peptide/protein validation. Manual validation of results in such studies is not feasible and objective enough for quality relevant interpretation. The necessity for tools enabling an automatic quality control is, therefore, important to produce reliable and comparable data in such big consortia as the Human Proteome Organization Brain Proteome Project. Standards and well-defined processing pipelines are important for these consortia. We show a way for choosing the right database model, through collecting data, processing these with a decoy database and end up with a quality controlled protein list merged from several search engines, including a known false-positive rate.

HUPO Brain Proteome Project: summary of the pilot phase and introduction of a comprehensive data reprocessing strategy.

The Human Proteome Organisation (HUPO) initiated several projects focusing on the proteome analysis of distinct human organs. The Brain Proteome Project (BPP) is the initiative dedicated to the brain, its development and correlated diseases. Two pilot studies have been performed aiming at the comparison of techniques, laboratories and approaches. With the help of the results gained, objective data submission, storage and reprocessing workflow have been established. The biological relevance of the data will be drawn from the inter-laboratory comparisons as well as from the re-calculation of all data sets submitted by the different groups. In the following, results of the single groups as well as the centralised reprocessing effort will be summarised and compared, showing the added value of this concerted work.
