Introduction: Anti-MuSK antibodies obstruct MuSK binding sites, leading to acetylcholine receptor (AChR) displacement within the postsynaptic membrane. MuSK MG patients often exhibit bulbar involvement and respiratory crises, setting them apart from other MG subtypes.
Case Presentation: A case of a 51-year-old male with MuSK MG that presented as isolated respiratory failure was compared to similar cases in the literature. The objectives were to explore the varied clinical presentations, treatment approaches, and outcomes, and to better understand the management of this subgroup of MG. The patient responded well to treatment with pyridostigmine, steroids, and intravenous immunoglobulins and immunosuppressive therapy.
Conclusion: A review of the literature revealed varied clinical presentations and treatment approaches among reported cases. Long-term prognosis appears favorable, requiring ongoing immunosuppressive management. Although the reported outcomes of MuSK MG patients with respiratory insufficiency show substantial heterogeneity, long-term prognosis appears favorable.

Human nasal epithelium (HNE) organoid models of SARS-CoV-2 infection were adopted globally during the COVID-19 pandemic once it was recognized that the Vero cell line commonly used by virologists did not recapitulate human infection. However, the widespread use of HNE organoid infection models was hindered by the high cost of media and consumables, and the inherent limitation of basal cells as a scalable continuous source of cells. The human Calu-3 cell line, generated from a lung adenocarcinoma, was shown to largely recapitulate infection of the human epithelium and to preserve the SARS-CoV-2 genomic fidelity.

Intercellular mitochondria transfer is an evolutionarily conserved process in which one cell delivers some of their mitochondria to another cell in the absence of cell division. This process has diverse functions depending on the cell types involved and physiological or disease context. Although mitochondria transfer was first shown to provide metabolic support to acceptor cells, recent studies have revealed diverse functions of mitochondria transfer, including, but not limited to, the maintenance of mitochondria quality of the donor cell and the regulation of tissue homeostasis and remodelling.

South Africa was the most affected country in Africa by the coronavirus disease 2019 (COVID-19) pandemic, where over 4 million confirmed cases of COVID-19 and over 102,000 deaths have been recorded since 2019. Aside from clinical methods, artificial intelligence (AI)-based solutions such as machine learning (ML) models have been employed in treating COVID-19 cases. However, limited application of AI for COVID-19 in Africa has been reported in the literature.

BackgroundHuman parainfluenza viruses (HPIV) commonly cause upper respiratory tract infections, with potential for severe lower respiratory complications. Understanding seasonal increases informs strategies to prevent HPIV spreading.AimWe examined the impact of COVID-19 on HPIV epidemiological and clinical patterns in Scotland using non-sentinel and sentinel surveillance data.
