Patients with advanced cancer were treated with immune checkpoint inhibitors and injected with COVID-19 vaccine to improve their prognosis without increasing pancreatic related adverse events.

To investigate immune checkpoint inhibitors (ICIs) induced pancreatic injury (ICIPI), the prognostic effect of COVID-19 vaccine on cancer patients, and whether COVID-19 vaccine increases the incidence of ICIPI. We conducted a retrospective study of 256 stage IV cancer patients treated with ICIs at The First Affiliated Hospital of Anhui Medical University from January 2020 to November 2022. Data collected included pancreatic enzyme levels, treatment outcomes, and vaccination status. Statistical significance was determined using the χ2 test and Kaplan-Meier method (p < .05). Compared to the control group, the vaccinated group (p < .0001) and the group with elevated pancreatic enzyme levels (p = .044) demonstrated higher disease control rates, indicating a direct benefit of vaccination and enzyme monitoring on treatment outcomes. Additionally, vaccinated patients demonstrated longer overall survival versus unvaccinated patients (23.9 months [95% CI, 22.3-25.5] vs 23.6 months [95% CI, 21.1-26.2], HR = 0.45 [95% CI, 0.24-0.86], p = .015) and progression-free survival (17.2 months [95% CI, 14.3-20.1] vs 13.7 months [95% CI, 11.3-16.1], HR = 0.54 [95% CI, 0.36-0.82], p = .004). Importantly, the analysis revealed no significant association between vaccination and pancreatic injury (p = .46). Monitoring pancreatic enzymes can effectively evaluate the therapeutic impact in patients using ICIs. Patients vaccinated against COVID-19 experience better immunotherapy outcomes without an increased risk of ICIPI.

The complete chloroplast genome of Calohypnum plumiforme (Wilson) (hypanceae, bryophyta).

Calohypnum plumiforme is a widely distributed moss in East Asia. In this study, Illumina sequencing data was used to assemble the complete chloroplast genome of C. plumiforme. The length of the circular genome is 124,037 bp. It contains a total of 121 genes, including 81 protein-coding, 36 tRNA, and 4 rRNA genes. The GC content of the chloroplast genome of C. plumiforme is 29.07%. The phylogenetic analysis suggested that C. plumiforme is sister to Calliergonella cuspidata. This study provides important sequence information for species identification and its phylogenetic relationship in the Bryopsida.
