Seroprevalence of antibodies against severe acute respiratory coronavirus 2 (SARS-CoV-2) in household dogs in Japan.

We investigated the seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among dogs in the Tokyo area via enzyme-linked immunosorbent assay (ELISA) using the spike protein as the target antigen. Plasma samples from 494 household dogs and blood-donor dogs were tested from July 2020 to January 2021. Of these samples, three showed optical densities that were higher than the mean plus two standard deviations of the mean of the negative-control optical densities (ODs). Of these three samples, only the sample with the highest OD by ELISA was confirmed positive by virus neutralization testing. The positive dog presented no SARS-CoV-2-related symptoms. The positivity rate of SARS-CoV-2 infections among dogs in the Tokyo area was approximately 0.2%.

Effects of Aromatherapy on Agitation in Patients with Dementia: A Systematic Literature Review and Meta-analysis

PURPOSE: The purpose of this study is to identify the effects of aromatherapy on agitation in patients with dementia using a meta-analysis and systemic literature review. METHODS: The EMBASE, CINAHL, MEDLINE, and other databases were searched up to November 2017. RESULTS: Of 419 publications identified, 12 met inclusion criteria, and 9 studies were used to estimate the effect size of aromatherapy. A total of 837 participants across all studies were included. The commonly applied methods were massage (50%), type of oil lavender (75%), and instrument Cohen-Mansfield Agitation Inventory (75%). A medium effect size of aromatherapy on agitation was identified (d=−0.56, I2=65.0%, p=.001). The massage group has lower effect size than the other group (d=−0.98, I2=0.0%, p=.001). CONCLUSION: Aromatherapy appears to be effective in improving agitation in patients with dementia. However, further studies for home-dwelling patients with dementia and with different types of aroma oil should be conducted in the future. In addition, research with well-designed are needed to assess the effects or aromatherapy on agitation.
