Rural-urban variation in willingness to donate blood in Ibadan Region, Nigeria.

BACKGROUND: Although there are ongoing blood donation campaigns in Nigeria, the prevalence of voluntary blood donation is about 10% and there is limited information about the determinants of blood donation behavior, especially across rural-urban geographic areas. This study examines the rural-urban differences in willingness to donate blood. METHOD: A cross-sectional study addressing adults from three rural and three urban communities was performed in 2021 to evaluate willingness, knowledge, attitude and practice of blood donation. RESULTS: A total of 287 individuals were surveyed. Most of the respondents across all communities have never donated blood (72%). Females aged 18-25, highly educated, and from urban communities were more incline to donate blood compared to their counterparts. The main reasons for not donating blood for rural dwellers were: never thought of it (39% vs 34.7%) and no one asked (34.4% vs 17%); fear of needles was declared mostly by urban dwellers (21.8% vs 12.5%) (p=0.02). CONCLUSIONS: Willingness to donate blood varies across rural and urban communities and is influenced by socio-demographic characteristics. The gap between willingness to donate and actual blood donation has consequences for the establishment of blood transfusion services. Targeted public health interventions are required to enhance awareness and knowledge and modify attitudes towards blood donation.

Late Complications of COVID-19; An Umbrella Review on Current Systematic Reviews.

Introduction: Several clinical manifestations have been discovered for COVID-19 since the emergence of SARS-CoV-2, which can be classified into early, medium, and long-term complications. However, late complications can be present after recovery from acute COVID-19 illness. The present study aims to comprehensively review the available evidence of late complications related to COVID-19. Method: A search was conducted, using keywords, through electronic databases, which included Scopus, Web of Science, PubMed, and Embase up to August 29, 2022. Study selection was performed according to a strict inclusion and exclusion criteria. The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) checklist was followed, and studies were appraised using the National Institute of Health (NIH) quality assessment and risk of bias tool. Results: In total, 50 studies were included, and nine distinct COVID-19 late complication categories were identified. A review of these studies revealed that neurologic and psychiatric (n=41), respiratory (n=27), musculoskeletal and rheumatologic (n=22), cardiovascular (n=9), and hepatic and gastrointestinal (n=6) complications were the most prevalent complications of long COVID-19. Conclusion: Almost all human body systems are affected by late complications of COVID-19 with different severity and prevalence. Fatigue and some other neuropsychiatric symptoms are the most common late complications among long COVID-19 patients. Respiratory symptoms including dyspnea (during exercise), cough, and chest tightness were the next most prevalent long-term complications of COVID-19. Since these complications are persistent and late, being aware of the signs and symptoms is essential for the healthcare providers and patients.
