Summary: Based on the analysis of data from the World Health Organization (WHO), the global mortality rate from chronic obstructive pulmonary disease (COPD) has been decreasing steadily, but there are several countries where the mortality rate for women is increasing. These trends are mainly attributed to changes in smoking habits, as well as the impact of air pollution and occupational exposures.

Summary: This study compared the outcomes of hospitalized patients with chronic obstructive pulmonary disease (COPD) and COVID-19 with matched COVID-19 patients without COPD. The results showed that COPD patients had more comorbidities, especially cardiovascular diseases, and a higher trend of 30-day mortality. Factors associated with 30-day mortality included high Charlson comorbidity index and previous cerebrovascular disease. Inhaled corticosteroids maintenance therapy was not associated with lower mortality.

Summary: The aim of the study was to assess COVID-19 vaccination coverage in COPD patients. The results showed that the vaccination coverage was high and there were significant differences in quality of life, severity of dyspnea, and infection rate between unvaccinated and vaccinated patients. Therefore, COVID-19 vaccination is crucial for COPD patients.

Summary: This study found that most patients with coronavirus disease-associated pulmonary aspergillosis (CAPA) are diagnosed shortly after admission, with the majority being treated in the ICU. Azole-resistant strains of Aspergillus fumigatus were common in patients, and voriconazole was the main treatment choice. The overall mortality rate was approximately 52.2%, with about one third of deaths attributed to CAPA.

Summary: COPD is a chronic airway disease that affects millions of people worldwide and is ranked as the third leading cause of death. Genetic susceptibility, environmental factors, and the combined effects of these factors play important roles in the development of COPD. The Hedgehog signaling pathway and its inhibitor HHIP are potential targets for therapeutic interventions in COPD.

Summary: This study investigated post-COVID-19 pulmonary fibrosis and found that older age and male gender were associated with higher mortality. Common symptoms included shortness of breath, cough, and fever. Radiographic findings showed bilateral lung infiltrates and ground glass opacity in COVID-19 patients with pulmonary fibrosis, and some patients required oxygen therapy.

Summary: The study identified shortness of breath as the strongest predictor for distinguishing between COVID-19 and influenza, followed by diarrhea. Higher lymphocyte count was predictive of COVID-19 compared to influenza and dengue. Cough and higher platelet count were associated with increased odds of COVID-19 compared to dengue, while symptoms like headache, joint pain, skin rash, and vomiting/nausea indicated dengue.

Summary: Only twenty percent of patients showed persistent lung abnormalities at 6 months after hospitalization for COVID-19 pneumonia in this study. These patients are predominantly older men with longer hospital stay. The presence of reticulations and consolidation on HRCT at hospital admission predicts the persistence of radiological abnormalities during follow-up.

Summary: This study established an efficient and stable system using Newcastle disease virus (NDV) as a vector to generate vaccines against SARS-CoV-2 in animals. The results showed that intramuscular immunization with rNDV-S induced the highest level of binding and neutralizing antibodies, as well as a strong S-specific T-cell response in mice. Intranasal immunization with rNDV-S1 mainly elicited a robust T-cell response. Overall, the NDV-vectored vaccine candidates were able to induce profound humoral and cellular immunity.

Summary: Over one billion people have received 2-3 dosages of an inactivated COVID-19 vaccine for basic immunization. The necessity of a booster dose to protect against the Omicron variant is still debated. In this study, researchers tested different vaccine platforms in mice and found that Omicron-adapted inactivated viral vaccines generated a neutralizing antibody response against Omicron. Heterologous immunization with COVID-19 vaccines based on different platforms also significantly increased cross-neutralizing antibody levels against Omicron and its sub-lineages. The findings suggest that Omicron-adapted vaccines based on heterologous platforms should be prioritized in future COVID-19 vaccination strategies.

Summary: Researchers isolated two neutralizing antibodies BA7208 and BA7125 from mice engineered to produce human antibodies. BA7125 showed broad neutralizing activity against all variants, while BA7208 was highly potent neutralizing against all tested SARS-CoV-2 variants except Mu. By combining BA7208 and BA7125, a biparatopic antibody BA7208/7125 that neutralized all tested variants was generated. Cryo-electron microscopy structure analysis showed that the contact residues of these antibodies were conserved and had minimal interactions with mutational residues in RBD of current variants. In addition, BA7208/7125 demonstrated potent therapeutic efficacy against Omicron BA.1 and BA.2 in mice and could be used for effective prophylaxis.

Summary: Neutralizing antibody (NtAb) levels are crucial in evaluating SARS-CoV-2 vaccines. The establishment of a unified WHO International Standard (IS) is important for accurate calibration of NtAb detection assays. The Chinese National Standard (NS) and WHO IS were developed in 2020, and a second-generation NS is urgently needed. Samples 33 and 66-99 have been developed as candidate NSs to minimize systematic errors and differences between Neut and PsN methods. Sample 66-99 has been approved as the second-generation NS with calibrated units for accurate NtAb testing.

Summary: This review summarizes the immune response features of immunodominant epitope-specific T cells targeting different SRAS-CoV-2 proteome structures after infection and vaccination, and analyzes the epitope immunodominance hierarchy in combination with multiple epitope-specific T cell attributes and TCR repertoire characteristics. The review also discusses the significant implications of cross-reactive T cells toward HCoVs, SRAS-CoV-2, and variants of concern, especially Omicron. This review may be essential for mapping the landscape of T cell responses toward SARS-CoV-2 and optimizing the current vaccine strategy.

Summary: This study collected sputum samples from COVID-19 patients and healthy controls, and found that extracellular vesicles (EVs) derived from the sputum of patients carry the SARS-CoV-2 virus and can infect normal cells. In addition, EVs in the samples of COVID-19 patients express proteins related to SARS-CoV-2 infection. These findings demonstrate the involvement of EVs in virus infection and immune responses, and provide insights into the pathogenesis of SARS-CoV-2 infection and the possibility of developing nanoparticle-based antiviral drugs.

Summary: Repurposing existing drugs, such as dicoumarol (DCM), as a potential inhibitor for SARS-CoV-2 infection in airway epithelial cells (AECs) has been found to have potent antiviral activity against Omicron variants. Early treatment of DCM can effectively inhibit Omicron replication in AECs, and the expression of NAD(P)H quinone oxidoreductase 1 (NQO1), a known DCM target, is correlated with disease severity and virus copy levels. DCM treatment disrupts signaling pathways associated with SARS-CoV-2 disease outcomes and can help formulate novel treatment strategies for COVID-19.

Summary: SARS-CoV-2 infection restricts the DNA recognition capacity of cGAS by its nucleocapsid protein, impairing the cGAS-induced IFN-I signaling. The study reveals that SARS-CoV-2 infection leads to the accumulation of released mtDNA, which triggers cGAS to activate IFN-I signaling.
