Africa experienced the third wave of the coronavirus disease in 2019, which caused an 18% rise in cases in most parts of the continent. As of January 2022, the region had an estimated 10.4 million cumulative cases and more than 233,000 deaths, which add up to the burden on the fragile healthcare system, which continues to face a shortage of staff and resources. In addition, the progression of the pandemic further threatens the supply of healthcare workers in Africa due to the increased risk of infection and death, where more than 10,000 healthcare workers in 40 countries have been infected with the virus. This is amid low vaccination coverage, with only 27% of healthcare workers in Africa being fully vaccinated against the disease. Despite the delayed start and slow progression of the pandemic in Africa, there are increasing concerns over the challenges on the African healthcare workers such as economic insecurity and stressful working conditions, which are associated with limited access to personal protective equipment and other vital resources such as ventilators. In addition, the pandemic further predisposes African healthcare workers to social stigma, burnout, insomnia, depression, and fear of safety in their families. The aim of this study is to highlight the challenges faced by African healthcare workers, provide recommendations for change, and emphasize the need to prioritize their physical and mental well‐being.
The role of vitamin D receptor (VDR) has been well established and extensively studied in the hair cycle. Its deficiency is also closely linked to several types of alopecia, including alopecia areata, telogen effluvium, and androgenetic alopecia (AGA). Since there is limited research on the correlation between androgenetic alopecia and low serum vitamin D levels, our review aims to find relevant articles and comprehensively present them. A review of the literature was performed to gain insight into AGA. Specifically, PubMed and Google Scholar databases were searched to identify any relevant articles with a focus on androgenetic alopecia, male pattern baldness, and serum vitamin D levels. References within the included articles were also reviewed and taken into the study if found appropriate. All articles that met the inclusion criteria were analyzed for demographics, clinical, laboratory, radiographic, treatment, and outcomes data. We found 13 relevant studies that elucidated the relationship between low serum vitamin D levels and androgenetic alopecia and included them in the review. We concluded that serum vitamin D might be a possible parameter for diagnosing the onset and severity of AGA. Vitamin D supplementation has proven to be useful in the regrowth of hair in non-human subjects. Vitamin D could be a valid therapeutic approach, such as topical vitamin D (calcipotriol) seems to be a good treatment option to regrow hair follicles and prevent miniaturization of follicles due to androgenetic alopecia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
