It is important that epidemiologists or public health workers work with infected cases to recall everyone they have close contact within the period that the cases might be able to transmit the infections. The results of a systematic review and meta-analysis suggest that a physical distancing of at least 1 m may be used as a criterion to estimate whether the contacts with the suspected or confirmed cases warrant investigations for infections [2]. Confidentiality must be strictly adhered to, to protect the privacy and confidentiality of infected cases and contacts, particularly when multiple counseling sessions are required [3]. If possible, the identity of infected cases to whom the contacts may have been exposed is to be kept confidential. Contacts should be informed about the need to isolate themselves from those who are not exposed. They should also be advised to continuously monitor their symptoms. They should be reminded that they may spread the infections if they harbor the virus even though they are asymptomatic. They are encouraged to stay separate from those who are not exposed, the so-called social distancing, at least 6 feet for a period of about 2 weeks after their last exposure to infected individuals. Some innovative methods to avoid a feeling of social isolation during the period will be needed [4]. It should be emphasized that contact tracing and investigation for possible infection are critical to prevent the spread of infection and proper care of contacts who are infected. Therefore, after contacts are identified, it is important to investigate whether they are actually infected. This should be carried out by skilled individuals who possess interpersonal skills, cultural sensitivity, and an understanding that strict confidentiality is mandatory to protect contact identity. These are specialized skills that must be well-trained. Contacts who might have infections should be referred for proper confirmation and management [5]. Yamamura et al. [6] in this issue investigate the infection rate among close contacts of patients with coronavirus disease in Japan. They found that the infection rate showed a rising trend from 11.1% in period 1 to 19.2% and 20.0% in periods 2 and 3, respectively. The authors speculated that one important factor of the rising trend in infection rate was the change in definition used for close contacts in Japan [6]. In addition, the variants differed between the periods [7] and some variants, such as the Omicron, have been shown to have strong immune escape [8]. The different degrees of vaccination coverage between different periods must have played a significant role in shaping the magnitude of attack rates.

Overexpression of miR-30c-2-p promotes apoptosis and inhibits proliferation of ACHN, Caki-1, and 786-O cells. miR-30c-2-3p targets TOP2A, which is elevated in RCC tissues and cells, whereas TOP2A silencing inhibits the proliferation ability of RCC cells. The miRNA-30c-2-3p inhibitor compromises TOP2A shRNA-induced apoptosis of RCC. RCC cells cotransfected with miRNA-30c-2-3p inhibitors and TOP2A shRNAs have a higher proliferation rate than those transfected with only TOP2A shRNAs.</p><p><strong>Conclusions: </strong>Collectively, our results verify that miRNA-30c-2-3p has a tumor suppressor property. miRNA-30c-2-3p inhibits the proliferation of RCC through regulation of TOP2A. The data provide a viable therapeutic target for RCC.</p>","PeriodicalId":8501,"journal":{"name":"Asian Biomedicine","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10561683/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41189606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
