Observational Study
Increasing dosages of low-molecular-weight heparin in hospitalized patients with Covid-19.
We conducted an observational cohort study in adult patients consecutively admitted for the respiratory illness Covid-19 to our hub hospital from March 9 to April 7, 2020. The high observed rate of venous thromboembolism prompted us to increase the prophylactic doses of enoxaparin from 40 mg daily up to 1 mg/kg twice daily in patients admitted to intensive care units (ICU), 0.7 mg/kg twice daily in high-intensity of care wards and 1 mg/kg daily in low-intensity of care wards. Patients on high enoxaparin doses were compared to those who received prophylaxis with the standard dosage. ⋯ Major bleeding occurred in four of 127 patients (3.1%) on the high enoxaparin dosage. In conclusion, in the cohort of patients with Covid-19 treated with high enoxaparin dosages we observed a 60% reduction of mortality and clinical deterioration and a 50% reduction of venous thromboembolism compared to standard dosage prophylaxis. However, 3% of patients on high enoxaparin dosages had non-fatal major bleeding.

Review Case Reports
Coronavirus Disease-2019 (COVID-19) and Pituitary Apoplexy: A Single-Center Case Series and Review of the Literature.
Pituitary apoplexy (PA) is a rare, but life-threatening, condition characterized by pituitary infarction and hemorrhage, most often in the setting of a preexisting adenoma. The risk factors and mechanisms associated with PA are poorly understood. Although neurovascular manifestations of coronavirus disease 2019 (COVID-19) infection have been documented, its association with PA has not yet been determined. ⋯ With the addition of our series to the literature, 10 cases of PA in the setting of COVID-19 infection have been confirmed. The present series was limited in its ability to draw conclusions about the relationship between these 2 entities. However, COVID-19 infection might represent a risk factor for the development of PA. Further studies are required.

Review[From SARS, MERS to COVID-19: a journey to understand bat coronaviruses].
From the beginning of this century, three coronaviruses (CoVs) have caused severe human respiratory diseases, including severe respiratory syndrome (SARS), Middle East respiratory syndrome (MERS) and corona virus disease 2019 (COVID-19), which outbroke in 2002-2003, 2012 and 2019-2020, respectively. These viruses are three different species belonging to Coronaviridae family, Betacoronavirus genus. Discovery of closely-related CoVs in bats indicates that bats are natural reservoirs of these viruses. ⋯ However, these bat viruses seem to be low pathogenic in human ACE2 transgenic mice compared with the SARS-CoV-2. These results imply that these bat CoVs have potential interspecies transmission to other animals and humans. Our work highlights the necessity of preparedness for future emerging infectious diseases caused by these CoVs.

Review[The COVID-19 battle at CHU Zhongnan and Leishenshan hospital: a summary of the global mobilization in China and reflections on the Wuhan experience].
The city of Wuhan, capital of Hubei, was the starting point of the Covid-19 epidemic and its doctors were led to develop novel strategies that have benefited the global fight in the country. But whatever strategies we hold up, the basic golden rule for controlling the pandemic has been early detection, reporting, isolation and treatment. The modalities of the battle were: swift action to block transmission with a vigorous, multifaceted response; resource allocation (a nationwide command system); Fangcang shelter hospitals; Broad community engagement: -provision of support via a volunteer network; People embraced behavioral change: -wearing masks and social distancing; Widespread testing: technical innovation; Science and technology curb the pandemic with research and digital technology; Free diagnosis and treatment for COVID-19. The success of our experience has provided valuable information to the international community in the fight against the pandemic.

Imaging findings of multisystem inflammatory syndrome in children associated with COVID-19.
A hyperinflammatory immune-mediated shock syndrome has been recognised in children exposed to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19). ⋯ Children with multisystem inflammatory syndrome showed pulmonary, cardiac, abdominal and brain imaging findings, reflecting the multisystem inflammatory disease. Awareness of the imaging features of this disease is important for early diagnosis and treatment.
