Revolutionizing stroke care in Africa: A mini review of the transformative potential of mobile stroke units

Stroke is a major health concern worldwide, and its impact is particularly pronounced across Africa. This paper delves into the challenges faced in African stroke care and explores the significant potential benefits of mobile stroke units (MSUs) in mitigating these issues. Key challenges include the limited healthcare infrastructure, funding constraints, difficulties reaching remote and rural areas, and shortages of qualified healthcare professionals, especially neurologists and stroke specialists. To address these challenges, recommendations are provided, emphasizing the importance of infrastructure development, sustainable funding mechanisms, solutions for rural accessibility, and healthcare workforce development through training programs and incentives. Additionally, the paper discusses prospects for MSUs in Africa, highlighting the potential for technology advancements to yield more cost-effective and compact MSU models. The integration of telemedicine capabilities within MSUs is examined to enhance communication with specialist physicians at remote hospitals, ultimately improving stroke care outcomes. Furthermore, data collection on MSU outcomes and their impact on stroke care is emphasized to inform evidence-based policies and enhance MSU operations. Collaboration and partnerships between governments, healthcare organizations, and international stakeholders are critical for facilitating MSU expansion. These partnerships can provide essential funding, expertise, and support for the implementation and sustainable operation of MSUs in Africa.

Determination of insecticide susceptibility in Culex quinquefasciatus Say adults by rapid enzyme microassays

Rapid enzyme microassays for the detection of resistance due to organophosphate and carbamate in individual field-collected strains of Culex quinquefasciatus adults were conducted. These tests allowed accurate differentiation by eye, on the basis of color changes of susceptible and resistant individuals. Two separate tests were conducted for the biochemical assays. In the insensitive acetylcholinesterase (AChE) test, acetylthiocholine iodide (ACTH) and 5,5-dithiobis-(2-nitrobenzoic acid) (DTNB) were used as substrate and coupling agent respectively. The resulting yellow chromophore indicated AChE activity. Test results showed that the color intensity decreased as increasing concentrations of propoxur were added, thereby confirming the susceptibility of the enzyme to inhibitor. Assay of non-specific esterase however, indicated elevated levels which were correlated with degree of malathion resistance. Electrophoretic data revealed the presence of 2 esterase bands in all strains. It was concluded that such a pattern was not contributory to malathion resistance in adults.
