Measles is a highly infectious viral illness and is one of the world's most contagious diseases that can affect all people if they have not been vaccinated or have not had it before. Before measles vaccine became available in 1963, major epidemic occurred approximately every 2 to 3 years and thus 99% of the people were thought to have been infected naturally with measles virus and got immune for life. ⋯ As vaccination coverage increases, the average age of measles infection can change to adolescents and young adults. In addition, the protective antibodies derived from vaccination might decrease gradually, and the risk of measles infection in young adults is increasing regardless of international travelling.

Restless legs syndrome (RLS) is a frequent comorbid condition associated with distinct unrelated diseases. While the incidence of RLS has not been definitively confirmed, RLS-like symptoms have been reported in a section of Asian population who also had hyperthyroidism. The prevalence of RLS is generally low in Asian populations. Under these circumstances, we hypothesized that in a population where RLS is common, such as in Brazil, RLS could manifest as a comorbid ailment alongside Graves' disease, a common hyperthyroid condition. ⋯ Our findings confirm that Graves' disease might trigger restless legs-like symptoms, while the condition of hyperthyroidism could also be complicated by definite RLS.

To investigate the effects of an intratympanic injection of dexamethasone combined with gentamicin on the expression level of serum P0 protein antibodies in patients with Meniere's disease (MD). ⋯ For patients with MD, dexamethasone combined with gentamicin can reduce the incidence of vertigo, tinnitus, and gait instability, but it has no effect on the efficacy or number of vertigo attacks 6 months after treatment. Therefore, the levels of myelin P0 protein antibodies after treatment can be used as predictors of vertigo at 6 months after treatment.

Recent emergence of SARS-CoV-2 in human communities as the first major zoonotic pandemics of the new millennium following the emergence of SARS-CoV and MERS-CoV has increased our awareness about the future threat of viral zoonosis. Although, several studies have been conducted for better understanding of these viruses` evolution, and designing the effective anti-viral drugs and vaccines, the impact of human beings on occurrence of zoonotic diseases has been less considered and discussed. Improvement in global health resulted in human population growth, increasing demand for animal proteins, more exposures to wildlife, zoonotic and degradation of environment, which have facilitated interspecies transmissions. ⋯ It seems that intensified revision of human lifestyle is the best strategy to prevent the potential devastating future zoonotic pandemics. Herein, the characteristics of SARS-CoV, MERS-CoV, SARS-CoV-2, their transmission routs, their pathogenicity, the therapeutic and prevention approaches including of attempts for designing of effective prophylactic vaccines, anti-viral drugs, and the animal models that have been used for these studies have been reviewed (Ref. 134). Keywords: SARS-CoV-2, COVID-19, pandemic, zoonosis, SARS, MERS.

Hypoxia leads to endothelial cell inflammation, apoptosis, and damage, which plays an important role in the complications associated with ischemic cardiovascular disease. As an oxidoreductase, p66Shc plays an important role in the regulation of reactive oxygen species (ROS) production and apoptosis. Ketamine is widely used in clinics. This study was designed to assess the potential protective effect of ketamine against hypoxia-induced injury in human umbilical vein endothelial cells (HUVECs). Moreover, we explored the potential mechanism by which ketamine protected against hypoxia-induced endothelial injury. ⋯ Ketamine reduces hypoxia-induced p66Shc expression and attenuates ROS accumulation via upregulating sirt1 in HUVECs, thus attenuating hypoxia-induced endothelial cell inflammation and apoptosis.
