ABSTRACT
The coronavirus disease 2019 (COVID-19) outbreak was the first pandemic to occur in a fully globalized society. The aims of the study were to explore the state of problematic smartphone use (PSU) and its risk factors during this incident. A total of 77,211 college students were surveyed online during the COVID-19 pandemic. Conducting latent profile analysis (LPA), we found the most support for a three-class model of subgroups: over-use group (17.3% of the sample), moderate-use group (54.8% of the sample), mild-use group (27.9% of the sample). The results of multinomial logistic regression show that college students who experienced an extreme negative impact from news reports were more likely to be included in the over-use group than in the mild-use group. These results providing insights that may help foster and develop appropriate and effective solutions to prevent PSU among college students during crises, such as reducing the coverage of negative news report.

ABSTRACT
This study reports outbreak of a new disease caused by Staphylococcus pseudintermedius (S. pseudintermedius) in raccoon dogs. The disease occurred in a breeding farm of raccoon dogs in Guan County of Shandong Province in China in August of 2019. 47% (425/896) of the raccoon dogs showed some abnormal symptoms; 17.6% (75/425) of which had severe skin and soft tissue infections (SSTIs), dyspnoea and severe pathological lesions in lungs, livers, etc; and 4.2% (18/425) of which died within 4 weeks. The pathogen of the disease was identified as S. pseudintermedius by mass spectrometer detection, animal pathogenicity tests, microscopic examination and biochemical reaction tests. Its nucleotide homology of 16S rRNA gene was 100% with that of other published strains, and its genotype was between the American and Brazilian strains from other animals. The isolated S. pseudintermedius strain from the diseased raccoon dogs could cause ulceration and suppuration in the skins and severe pathological lesions not only in raccoon dogs, but also in mice; and it is confirmed as a methicillin-resistant S. pseudintermedius (MRSP) strain by the amplification of mecA gene; and 12 sensitive drugs were screened by drug sensitivity tests. Full attention should be paid to the great economic loss and the potential zoonotic risk caused by the S. pseudintermedius in raccoon dogs, and this study can provide a reference for the clinical diagnosis and treatment of this new disease.
