ReviewLiving biobank: Standardization of organoid construction and challenges.
In multiple areas such as science, technology, and economic activities, it is necessary to unify the management of repetitive tasks or concepts by standardization to obtain the best order and high efficiency. Organoids, as living tissue models, have rapidly developed in the past decade. Organoids can be used repetitively for in vitro culture, cryopreservation, and recovery for further utilization. ⋯ Given the increasing importance of organoids in the development of new drugs, standardized operation, and management in all steps of organoid construction is an important guarantee to ensure the high quality of products. In this review, we systematically introduce the standardization of organoid construction operation procedures, the standardization of laboratory construction, and available standardization documents related to organoid culture that have been published so far. We also proposed the challenges and prospects in this field.

Although coronavirus disease 2019 (COVID-19) vaccines exhibit diverse side effects, taste and saliva secretory disorders have remained poorly understood despite their negative impact on the overall quality of life. The present study aimed to characterize oral adverse effects following COVID-19 vaccination and assess their similarities with oral symptoms in COVID-19 patients. A literature search was conducted in databases, including PubMed, LitCovid, and Google Scholar, to retrieve relevant studies. ⋯ Considering that oral adverse effects following COVID-19 vaccination share some characteristics with oral symptoms in COVID-19 patients, it is speculated that the spike protein derived from COVID-19 vaccination and SARS-CoV-2 infection may be pathophysiologically responsible for taste and saliva secretory disorders. This is because such spike protein has the potential to interact with ACE2 expressed on the relevant cells, produce proinflammatory cytokines, and form antiphospholipid antibodies. Our results do not deny the advantages of COVID-19 vaccination, but attention should be paid to post-vaccination oral effects in addition to COVID-19 oral symptoms.

To study the prognostic significance of hematologic indices: neutrophils/lymphocytes (N/L), platelets/lymphocytes (P/L) and lymphocytes/C-reactive protein (L/CRP) in relation to the complicated course of new coronavirus infection (COVID-19), as well as their correlation with COVID-19 course severity indices and endothelial dysfunction marker sVCAM-1. ⋯ Hematologic indices N/L, P/L and L/CRP are correlated with clinical, laboratory and instrumental characteristics of COVID-19 severity, presence of endothelial dysfunction (P/L and L/CRP) and allow predicting the development of cytokine storm (N/L and L/CRP).

Background and Objectives: Coinfection with SARS-CoV-2 and extrapulmonary tuberculosis (extraPTB) presents unique clinical challenges due to dual inflammatory responses and potential differences in patient profiles compared to those with SARS-CoV-2 infection alone. This study uniquely contributes to the underexplored interaction between extraPTB and SARS-CoV-2, focusing on systemic inflammation as a critical determinant of outcomes. Materials and Methods: This retrospective, cross-sectional study included 123 patients aged 19-91 years, hospitalized at Victor Babeș Hospital in Timișoara from March 2020 to March 2022. ⋯ Low SpO2 and elevated IL-6 were significant predictors of mortality, with severe symptoms tripling fatality odds. Conclusions: Coinfection with extraPTB and SARS-CoV-2 is associated with younger age, heightened systemic inflammation, and longer hospital stays but does not significantly increase mortality risk compared to SARS-CoV-2 alone. These findings underscore the importance of monitoring systemic inflammatory markers and developing tailored management strategies to improve long-term care outcomes for coinfected patients, especially in resource-limited settings.
