COVID-19 mortality among solid organ transplant recipients and candidates before specific vaccine availability in Colombia.

Introduction: Coronavirus disease 2019 (COVID-19) is a life-threatening disease that was declared a pandemic in March 2020. Organ transplant recipients are vulnerable to infection and complications from COVID-19. The objective of this study was to investigate the rates of infection, mortality, and case-fatality ratios (CFR) in solid organ transplant recipients and patients on the waiting list for organ allocation in the period prior to the availability of specific vaccines.

Equity, intercultural approaches, and access to information on traditional, complementary, and integrative medicines in the Americas.

Access to information and intercultural approaches in the field of health are essential for the elimination of inequities in health access and care. Intercultural models such as traditional, complementary, and integrative medicine (TCIM) are an important part of health care in most countries and often contribute to expanding access to primary health care. Despite legal recognition and policies to integrate TCIM into health systems, their contribution to health, well-being, and people-centered care to achieve universal health is still underestimated.

Reprogramming of cassava (Manihot esculenta) microspores towards sporophytic development.

Gametes have the unique potential to enter the sporophytic pathway, called androgenesis. The plants produced are usually haploid and recombinant due to the preceding meiosis and they can double their chromosome number to form doubled haploids, which are completely homozygous. Availability of the doubled haploids facilitates mapping the genes of agronomically important traits, shortening the time of the breeding process required to produce new hybrids and homozygous varieties, and saving the time and cost for inbreeding.
