Here we introduce a MIxS extension to facilitate the recording and cataloguing of metadata from samples related to hydrocarbon resources. The proposed MIxS-HCR package incorporates the core features of the MIxS standard for marker gene (MIMARKS) and metagenomic (MIMS) sequences along with a hydrocarbon resources customized environmental package. Adoption of the MIxS-HCR standard will enable the comparison and better contextualization of investigations related to hydrocarbon rich environments. The insights from such standardized way of reporting could be highly beneficial for the successful development and optimization of hydrocarbon recovery processes and management of microbiological issues in petroleum production systems.

BACKGROUND: Functional limitations and physical disabilities associated with aging and chronic disease are major concerns for human societies and expeditious development of function-promoting therapies is a public health priority. METHODS: Expert panel discussion. RESULTS: The remarkable success of Operation Warp Speed for the rapid development of COVID-19 vaccines, COVID-19 therapeutics, and of oncology drug development programs over the past decade have taught us that complex public health problems such as the development of function-promoting therapies will require collaboration among many stakeholders, including academic investigators, the National Institutes of Health, professional societies, patients and patient advocacy organizations, the pharmaceutical and biotechnology industry, and the U.S. Food and Drug Administration. CONCLUSIONS: There was agreement that the success of well designed, adequately powered clinical trials will require careful definitions of indication/s, study population, and patient-important endpoints that can be reliably measured using validated instruments, commensurate resource allocation, and versatile organizational structures such as those used in Operation Warp Speed.

BACKGROUND: Individual risk assessment allows donors to be evaluated based on their own behaviors. Study objectives were to assess human immunodeficiency virus (HIV) risk behaviors in men who have sex with men (MSM) and estimate the proportion of the study population who would not be deferred for higher risk HIV sexual behaviors. STUDY DESIGN AND METHODS: Cross-sectional survey and biomarker assessment were conducted in eight U.S. cities. Participants were sexually active MSM interested in blood donation aged 18-39 years, assigned male sex at birth. Participants completed surveys during two study visits to define eligibility, and self-reported sexual and HIV prevention behaviors. Blood was drawn at study visit 1 and tested for HIV and the presence of tenofovir, one of the drugs in oral HIV pre-exposure prophylaxis (PrEP). Associations were assessed between HIV infection status or HIV PrEP use and behaviors, including sex partners, new partners, and anal sex. RESULTS: A total of 1566 MSM completed the visit 1 questionnaire and blood draw and 1197 completed the visit 2 questionnaire. Among 1562 persons without HIV, 789 (50.4%) were not taking PrEP. Of those not taking PrEP, 66.2% reported one sexual partner or no anal sex and 69% reported no new sexual partners or no anal sex with a new partner in the past 3 months. CONCLUSION: The study found that questions were able to identify sexually active, HIV-negative MSM who report lower risk sexual behaviors. About a quarter of enrolled study participants would be potentially eligible blood donors using individual risk assessment questions.

Requiring regional or in-country confirmatory clinical trials before approval of drugs already approved elsewhere delays access to medicines in low- and middle-income countries and raises drug costs. Here, we discuss the scientific and technological advances that may reduce the need for in-country or in-region clinical trials for drugs approved in other countries and limitations of these advances that could necessitate in-region clinical studies.
