Progression of confirmed COVID-19 cases after the implementation of control measures [Originally published in Rev. bras. ter. intensiva]

We noted that China (excluding Hubei Province), Hubei Province, and South Korea have been effective in their deceleration of the growth rates of COVID-19 cases. The effectiveness of the measures taken by these countries could be seen after 1 to 2 weeks of their application. In Italy and Spain, control measures at the national level were taken at a late stage of the epidemic, which could have contributed to the high propagation of COVID-19.

Adults at high-risk of severe coronavirus disease-2019 (Covid-19) in Brazil [Originally published in Rev. Saúde Pública, vol.54]

Adults at risk of severe Covid-19 in Brazil varied from 34.0% (53 million) to 54.5% (86 million) nationwide. Less-educated adults present a 2-fold higher prevalence of risk factors compared to university graduated. We found no differences by sex and race/ethnicity. São Paulo, Rio de Janeiro, Minas Gerais, and Rio Grande do Sul were the most vulnerable states in absolute and relative terms of adults at risk. Image: Pop & Zebra. Read More →

Rational perspectives on risk and certainty for dentistry during the COVID-19 pandemic

Clinical dental practice exposes the dental team and patients to infectious airborne disease agents, due to the close contact during clinical care, and the infectious aerosols from most dental procedures. The U.S. Centers for Disease Control and Prevention (CDC), the American Dental Association (ADA) and other organizations developed recommendations to address the specific risk profile of SARS-CoV-2 transmission, adding additional protective measures to established standard precautions.

Behavior of scientific production on severe acute respiratory syndrome

The data presented demonstrate the high level of interest of the scientific community in the subject. It was possible to identify 82 authors composing an Elite group of Authors, whose productivity was 66.1%. The United States, China and Saudi Arabia are the countries that most formed Collaboration Networks. Read More →

Health belief model for coronavirus infection risk determinants [Originally published in Rev. Saúde Pública, vol. 54]

Our health belief model-based questionnaire using quantitative measures enabled the confirmation of popular beliefs about covid-19 infection risks. The advantage in our approach lays in the possibility of quickly, directly and quantitatively identifying individual belief profiles for each dimension in the questionnaire, serving as a great ally for communication processes and public health education.

Can we manage prophylactic therapy in COVID-19 patients to prevent severe illness complications? [Originally published in J. vasc. bras., vol.19]

Many patients with COVID-19 have thromboembolic complications that worsen their prognosis. Herein, the authors propose a modified version of the CHA2DS2-VASc score, including 1 point for COVID-19, so that prophylaxis to protect against thromboembolic events would be indicated before the condition becomes severe. The advantages of this modification would be prevention of the patient’s condition worsening due to thromboembolic problems and reduction of the likelihood of a need for intensive care and mechanical ventilation, reducing mortality.

Speech therapy, breastfeeding and COVID-19: information to speech therapist [Originally published in CoDAS, vol.32 no.3]

Currently, there is no evidence that the Corona Virus can be transmitted through breast milk, but it is known that an infected mother can transmit the virus through respiratory droplets during breastfeeding8. In a study carried out with six newborns of infected mothers, who were breastfeeding their babies, all samples were negative for the virus. Image: Wes Hicks. Read More →

Social media: friend or foe in the COVID-19 pandemic? [Originally published in Clinics, vol. 75]

Social media is extremely important to fight this contagious disease, not only to get information and be updated about it but also to understand how it spreads, how people interact, and how we can respond to it. As Heidi Tworek, assistant professor at University of British Columbia in Canada, said on Twitter, “Communications in a public health crisis are as crucial as medical intervention … in fact, communications policies ARE a medical intervention”. We didn’t have this tool a hundred years ago, but now we must use it wisely in every way we can to overcome this pandemic. Image: Hal Gatewood. Read More →

Why is SARS-CoV-2 infection milder among children? [Originally published in Clinics, vol. 75]

On the last April 27th, Bi et al. published a retrospective cohort study from Shenzhen, China demonstrating that the rate of infection in children below 10 years was similar to the population average, although children are less likely to develop severe symptoms. Image: Vanessa Bucceri. Read More →

Expert recommendations for the care of newborns of mothers with COVID-19 [Originally published in Clinics, vol. 75]

Despite the lack of scientific evidence regarding the potential for viral transmission to their fetus in pregnant mothers diagnosed with or suspected of COVID-19, it is important to elaborate the lines of care by specialists from hospitals caring for suspected and confirmed COVID-19 cases to guide multidisciplinary teams and families diagnosed with the disease or involved in the care of pregnant women and newborns in this context. Multidisciplinary teams must be attentive to the signs and symptoms of COVID-19 so that decision-making is oriented and assertive for the management of the mother and newborn in both the hospital setting and at hospital discharge.

Surgical Practice in the Current COVID-19 Pandemic: A Rapid Systematic Review [Originally published in Clinics, vol. 75]

Several additional recommendations with respect to surgical practice or surgical staff were also assessed and discussed, such as performing laparoscopic surgeries and avoiding the use of electrocauterization. On the basis of the current literature, we concluded that any surgery that can be delayed should be postponed. COVID-19 screening is strongly recommended for all surgical cases. Moreover, surgical staff should be reduced to the essential members and provided with institutional psychological support. Image: Paul Felberbauer. Read More →

Susceptibility of the Elderly to SARS-CoV-2 Infection: ACE-2 Overexpression, Shedding, and Antibody-dependent Enhancement (ADE) [Originally published in Clinics, vol. 75]

We raise two main points, i) increased ACE-2 expression in pulmonary and heart tissues in users of chronic angiotensin 1 receptor (AT1R) blockers; and ii) antibody-dependent enhancement (ADE) after previous exposure to other circulating coronaviruses. We believe that these points are pivotal for a better understanding of the pathogenesis of severe COVID-19, and must be carefully addressed by physicians and scientists in the field.

Associations of moderate to vigorous physical activity and sedentary behavior with depressive and anxiety symptoms in self-isolating people during the COVID-19 pandemics: A cross-sectional survey in Brazil

To evaluate the associations of moderate to vigorous physical activity (MVPA), vigorous physical activity (VPA), moderate physical activity (MPA), and sedentary behavior (SB) with depressive, anxiety, and co-occurring depressive and anxiety symptoms (D&A) during the COVID-19 pandemic in Brazil. Higher MVPA and VPA levels are associated with lower odds of depressive, anxiety and D&A symptoms. Higher SB is associated with higher odds of depressive symptoms. Read More →
