Background: COVID-19 counts 46 million people infected and killed more than 1.2 million. Hypoxaemia is one of the main clinical manifestations, especially in severe cases. HIF1α is a master transcription factor involved in the cellular response to oxygen levels. The immunopathogenesis of this severe form of COVID-19 is poorly understood.
Methods: We performed scRNAseq from leukocytes from five critically ill COVID-19 patients and characterized the expression of hypoxia-inducible factor1α and its transcriptionally regulated genes. Also performed metanalysis from the publicly available RNAseq data from COVID-19 bronchoalveolar cells.
Results: Critically-ill COVID-19 patients show a shift towards an immature myeloid profile in peripheral blood cells, including band neutrophils, immature monocytes, metamyelocytes, monocyte-macrophages, monocytoid precursors, and promyelocytes-myelocytes, together with mature monocytes and segmented neutrophils. May be the result of a physiological response known as emergency myelopoiesis. These cellular subsets and bronchoalveolar cells express HIF1α and their transcriptional targets related to inflammation (CXCL8, CXCR1, CXCR2, and CXCR4); virus sensing, (TLR2 and TLR4); and metabolism (SLC2A3, PFKFB3, PGK1, GAPDH and SOD2).
Conclusions: The up-regulation and participation of HIF1α in events such as inflammation, immunometabolism, and TLR make it a potential molecular marker for COVID-19 severity and, interestingly, could represent a potential target for molecular therapy. Key messages Critically ill COVID-19 patients show emergency myelopoiesis. HIF1α and its transcriptionally regulated genes are expressed in immature myeloid cells which could serve as molecular targets. HIF1α and its transcriptionally regulated genes is also expressed in lung cells from critically ill COVID-19 patients which may partially explain the hypoxia related events.

Unexplained fever poses significant diagnostic challenges in resource-limited settings like Bamako, Mali, where overlapping endemic diseases include malaria, HIV/AIDS, yellow fever, typhoid, and others. This study aimed to elucidate the infectious etiologies of acute febrile illnesses in this context. Acute febrile patients of any age were enrolled after informed consent or assent.

Objectives: To describe changes in respiratory syncytial virus (RSV) epidemiology, its associated clinical outcomes and predictors of severe acute lower respiratory tract infection (ALRTI) pre- and post-COVID-19.
Methods: In this retrospective cohort, we analysed data from electronic medical record of children <5 years who were hospitalized at Jordan University Hospital with RSV-associated ALRTI from 2018 to 2022.
Results: 325 inpatients with respiratory infections were included.

Objective: The recent outbreak of monkeypox (mpox) poses significant public health challenges, particularly for immunocompromised populations such as patients with cancer. However, misinformation poses a significant challenge during new outbreaks for patients with chronic diseases, as observed during the COVID-19 pandemic. Therefore, we aimed to assess perspectives and knowledge of patients with cancer on mpox and their willingness to receive mpox vaccination.

Objectives: To evaluate the incidence and characteristics of severe infections in rheumatic patients receiving biologic disease-modifying anti-rheumatic drugs (bDMARDs) after kidney transplantation.
Methods: This multicenter, retrospective study included 38 patients who had undergone kidney transplantation and received bDMARDs for rheumatic diseases. Demographic, clinical, and treatment data were collected.

Human adenovirus (HAdV) is an important pathogen causing pediatric acute respiratory illness (ARI) before COVID-19 pandemic. Since January 2023, China has reported ARI outbreaks attributed to Mycoplasma pneumoniae and other respiratory viruses. In this study, a total of 276 737 pediatric patients with ARI were enrolled from January 2023 to April 2024.
