A total of 333 individuals with HIV/HBV co-infection and undergoing long-term ART were enrolled in this study. Demographic, clinical, and biochemical data were collected at baseline and during annual visits. Group-based trajectory models (GBTMs) were used to detect the patterns of liver fibrosis evolution based on longitudinal data of fibrosis-4 (Fib-4) and aspartate aminotransferase to platelet ratio index (APRI) scores. Logistic regression analysis was performed to identify baseline predictors of liver fibrosis evolution. The median age of all participants was 33 years. Among them, 89.5% initially received TDF-containing ART. GBTMs identified two distinct patterns of liver fibrosis evolution using either APRI or Fib-4 scores. The majority of individuals (78.5% for APRI and 75.3% for Fib-4; pattern A) showed stable or low fibrosis with no progression, while the remaining participants showed regression from high fibrosis levels (21.5% for APRI and 24.7% for Fib-4; pattern B). Pattern A participants were younger and had higher CD4<sup>+</sup> cell counts, higher lymphocyte cell counts, higher white blood cell counts, and lower platelet counts at baseline compared to pattern B participants.

NiV leads to severe respiratory disease and encephalitis in humans and animals, with a mortality rate of up to 75%. Despite the grave threat to public health and global biosecurity, no medical countermeasures are available for humans. Here, based on self-assembled ferritin nanoparticles (FeNPs), we successfully constructed two candidate FeNP vaccines by loading mammalian cells expressing NiV sG (residues 71–602, FeNP-sG) and G<sub>head</sub> (residues 182–602, FeNP-G<sub>head</sub>) onto <em>E. coli</em>-expressed FeNPs (FeNP-sG and FeNP-G<sub>head,</sub> respectively) through Spycatcher/Spytag technology. Compared with sG and G<sub>head</sub> alone, FeNP-sG and FeNP-G<sub>head</sub> elicited significant NiV specific neutralizing antibody levels and T-cell responses in mice, whereas the immune response in the FeNP-sG immunized group was greater than that in the FeNP-G<sub>head</sub> group. These results further demonstrate that sG possesses greater antigenicity than G<sub>head</sub> and that FeNPs can dramatically enhance immunogenicity. Furthermore, FeNP-sG provided 100% protection against NiV challenge in a hamster model when it was administered twice at a dose of 5 μg/per animal.

This prospective cohort included 48,830 hospitalized coronavirus disease 2019 (COVID-19) patients across three hospitals in Shanghai, China, between 23 March and 15 May, 2022. Systematic nucleic acid testing was performed using RT-PCR Cycle threshold (Ct) value as a proxy of viral load. We analyzed the kinetic characteristics of viral shedding by clinical severity and identified associated risk factors. The study comprised 31.06% asymptomatic cases, 67.66% mild-moderate cases, 1.00% severe cases, 0.29% critical and fatal cases. Upon admission, 57% of patients tested positive, with peak viral load observed at 4 days (median Ct value 27.5), followed by a decrease and an average viral shedding time (VST) of 6.1 days (Interquartile range, 4.0–8.8 days). Although viral load exhibited variation by age and clinical severity, peak Ct values occurred at similar times. Unvaccinated status, age exceeding 60, and comorbidities including hypertension, renal issues kidney dialysis and kidney transplantation, neurological disorders, rheumatism, and psychotic conditions were found to correlate with elevated peak viral load and extended VST. Asymptomatic cases demonstrated a 40% likelihood of contagiousness within 6 days of detection, while mild-moderate and severe cases exhibited post-symptom resolution infectious probabilities of 27% and over 50%, respectively.

Currently, no vaccines or specific drugs are approved for clinical use. The hosts of adenoviruses are strictly species-specific, which strongly limits the development of vaccines and drugs against HAdVs. In this study, immunocompetent BALB/c mice were challenged with different doses of human adenovirus type 5 (HAdV-5) via tail intravenous injection (<em>i.v.</em>). All mice challenged with a high dose of HAdV-5 (3.2 × 10<sup>10</sup> TCID<sub>50</sub>/kg) died within 3–5 days, while those receiving a low dose of HAdV-5 (8 × 10<sup>9</sup> or 4 × 10<sup>9</sup> TCID<sub>50</sub>/kg) survived. Interestingly, among the mice receiving a medium dose of HAdV-5 (1.6 × 10<sup>10</sup> TCID<sub>50</sub>/kg), 60% (n = 3/5) of male mice died, while all female mice survived. This suggests that male mice may be more susceptible to HAdV-5 infection than female mice, consistent with clinical findings in children. HAdV-5 DNA was mainly distributed in the liver, followed by the spleen and lung. Pathological changes were observed in the lung, liver, and spleen, with severity increasing in correlation with the virus challenge dosage. Transcriptome and qPCR analyses of the liver indicated that the down-regulated expression of the <em>H2-Aa</em>, <em>H2-Ea-ps</em>, <em>CD74</em>, and <em>H2-Eb1</em> genes in male mice, as well as the <em>AHR</em> gene in female mice, may contribute to the observed higher mortality rates in male mice.
