wly diagnosed COVID-19 cases and "tosse" (cough; r=0.65; p=0.008) or "febbre" (fever; 0.69; p=0.004) become statistically significant with a 3-week delay. All symptoms were also significantly inter-correlated. Conclusions; Continuously monitoring the volume of Google searches and mapping their origin can be a potentially valuable instrument to help predicting and identifying local recrudescence of COVID-19.ackground During the pandemic of COVID-19, the overwhelm of infected patients created an exponential surge for ICU and ward beds. As a result, a major proportion of elective surgeries was postponed. However, various emergency and urgent procedures were allowed. Due to the mortality complications of hepatopancreatobiliary issues, we decided to afford urgent procedures under intensive protective arrangements. Method and results In our ward (liver transplant), 4 ICU beds and 16 ward beds were allocated to non-COVID-19 patients. A total of 36 hepatopancreatobiliary procedures were managed for one month. All the surgeries were afforded under personal protective equipment and other intensive protective arrangements for personnel and patients. During 6 weeks following the surgery, all patients were followed up through telemedicine and no new case of COVID-19 was detected. Conclusion In general, it appears that intensive protections could significantly reduce the number of COVID-19 incidence among patients with co-morbidities who undergo invasive procedures. Physical inactivity is expected to happen during the COVID-19 pandemic through home quarantine measures. The aim of this study was to develop, validate and perform the reliability of the questionnaire "Physical exercise (PE) level before and during social isolation (PEF-COVID19)" to evaluate the level of PE during the social distancing due to the COVID-19 pandemic and to try to identify changes in the daily life of the individuals. This transversal study was developed to measure psychometric properties of the questionnaire PEF-COVID19. The survey was divided into 4 sections including subjects' characterization, social isolation update and physical exercise performed, pain, anxiety and stress before and during COVID-19 pandemic. After the survey construction in Portuguese language (Brazil), the survey was transferred to an online digital platform (Google® forms). The Construct, Clarity and Relevance Validation strategy was judged by a panel of experts and the validity index (VI) were calculated. https://www.selleckchem.com/products/ck-586.html The reliability was evaluated through the test-retest interrater reliability and measured through the intraclass correlation coefficient (ICC) and Kappa coefficient (KC). Twenty-five experts participated of the survey validity and 34 respondents from the target population participated of the test-retest reliability. The general average measures for VI were all above 0.84 and test-retest ICC and KC were 0.89 and 0.88, respectively. This survey was considered valid and reliable to be applied to the general population over 18 years-old to investigate the PE practice and psychological aspects during the social distancing due to the COVID-19 pandemic, a public health problem.

The COVID-19 outbreak is now a pandemic disease reaching as much as 210 countries worldwide with more than 2.5 million infected people and nearly 200.000 deaths. Amplification of viral RNA by RT-PCR represents the gold standard for confirmation of infection, yet it showed false-negative rates as large as 15-20% which may jeopardize the effect of the restrictive measures taken by governments. We previously showed that several hematological parameters were significantly different between COVID-19 positive and negative patients. Among them aspartate aminotransferase and lactate dehydrogenase had predictive values as large as 90%. Thus a combination of RT-PCR and blood tests could reduce the false-negative rate of the genetic test. We retrospectively analyzed 24 patients showing multiple and inconsistent RT-PCR, test during their first hospitalization period, and compared the genetic tests results with their AST and LDH levels. We showed that when considering the hematological parameters, the RT-PCR false-negative rates were reduced by almost 4-fold. The study represents a preliminary work aiming at the development of strategies that, by combining RT-PCR tests with routine blood tests, will lower or even abolish the rate of RT-PCR false-negative results and thus will identify, with high accuracy, patients infected by COVID-19.

Various measures have been taken by the Italian Government to contain and mitigate the COVID-19 outbreak and on March 11th a decree called "I stay at home" put the whole nation under lockdown. Our aim is to describe sociodemographic and transmission profile of COVID-19 cases that were transmitted before and after the introduction of the decree in the Bologna Local Health Authority. Cases were classified as transmitted before or after the decree according to the date of last contact with a COVID-19 case or, if this date was unavailable, we used the date of onset of symptoms considering the incubation period. Sociodemographic, clinical and epidemiological information was collected by using the infectious disease monitoring database, hospital discharge, deprivation index and long term care facility databases. In the period after the publication of the decree, there were more elderly, females, strangers, retired, residents in nursing homes and deprived people than in the first period. There were also more health care personnel and less professionals/managers, sales or office workers. In both phases, family is mentioned as the first community attended although less frequently in the second group. The profile of the new COVID-19 cases changed during the outbreak suggesting a differential effect of lockdown measures on the population. An equity lens should be used when analyzing the impact of pandemia and the measures taken to curb it.
