Overall, the prevalence in Colombia was 2.85%. Our data represent an important first step to understanding the current state of rosacea in Colombia. The prevalence of rosacea in Colombia is the highest in Latin America among a few reports published, which might be explained by geographic features. However, contrary to our expectations, the prevalence is lower than that in some European countries. We postulate that this finding may be due to methodological differences.
Given that the COVID-19 era has changed the behavior of all individuals, and since previous reports about its possible impact on atopic dermatitis (AD) patients remained speculative, in this survey we aimed to explore the real impact of COVID-19 among AD patients.
All participants provided verbal consent prior to completing the survey. A 37-question web-based survey with no personal identifiers was sent to 212 previously identified AD patients. Itching, sleep disturbances, SARS-CoV-2, illness cost, economic dependence, monthly income, and monthly investment in AD before and during the pandemic, were all included in the analysis.
A response rate of 73.1% was obtained. The mean age of participants was 30 years-old, and 57% were women. Around 75% reported AD worsening, and 59.4% of the patients reported sleep problems. Uncertainty, anxiety, and pessimism were frequent during the pandemic. Only 1.3% tested positive for SARS-CoV-2, and it was only significantly associated with comorbidities (p=0.03; Chi

Test). A significant difference was found in economic dependence and monthly income when compared between before and during the pandemic.
This study provides probably the best possible assessment of the clinical, social, and economic effects of the pandemic on patients with an already proven diagnosis of AD.
The results in this paper indicate that mitochondrial permeability transition is activated by dysfunction of the respiratory chain caused by anaerobiosis, exhaustion of the oxidative substrate, and antimycin A, in the presence of 100 μM Ca2+. Membrane damage coincides with the collapse of the electric gradient. The opening of the non‐selective pore is prevented by cyclosporin A.
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.
