The COVID-19 pandemic threatens physical and mental health of adolescents worldwide and has caused increased risks of dependence and addiction on Internet use during home quarantine. Internet addiction has become an important issue in mental healthcare and its prevention and treatment is of great significance for the development of adolescents. We have gathered leading experts in China and developed this guideline to provide references and suggestions to prevent and treat Internet addiction in adolescents during home quarantine and help them get through the pandemic.

The association of cardiovascular disease (CVD) and psychosocial stress (PSS) is a bidirectional function, whereby the two conditions create a self-reinforcing feedback loop. Either can incite and/or magnify the other, prognosis consequently deteriorates and spontaneous remission is unlikely. Several studies show that even subclinical PSS increases mortality. Recent evidence suggests that stress exhibits a strong dose–response toxicity on cardiovascular health with increased levels of PSS directly correlating to additional morbidity and mortality. As such, it will be important that future research considers PSS as a continuous variable capable of causing a spectrum of disease. This article proposes targeted exercise routines as the most efficient therapy for both arms of the feedback loop. A consistent body of data indicates that regular physical activity eases the PSS burden while simultaneously lowering CVD risk. Exercise therapy, mindfulness training, and interventions targeting positive psychological well-being stress management are indispensable therapies, particularly for at-risk and already established cardiovascular patients. Indeed, comprehensive cardiac rehabilitation and exercise training programs inclusive of education, lifestyle, and psychological measures in addition to fitness training are a potent multifaceted therapy for improving quality of life and overall prognosis.

Purpose: COVID-19 has destabilized the routine across the members of cardiac surgery including the postgraduates. In view of this, we conducted a survey among the residents to capture their thoughts on the impact of COVID-19. Methods: An electronic questionnaire was constructed and sent to the residents on May 17, 2020. Participation was voluntary and anonymized. The survey ended on May 27, 2020. Results: A total of 91 postgraduates across the country participated in the survey. A strong majority was attributed when more than 50% of the postgraduates agreed on an opinion, and a moderate majority was attributed when 40%–50% of postgraduates agreed on an opinion. Among the specialties, thoracic surgery and peripheral posting were severely affected, and it was the surgical skill which was severely affected compared to their lectures and thesis work. Multi-institutional collaboration teaching programs were useful in understanding the protocols of different units across the country. Conclusion: Virtual lectures have to continue integrating different institutions for the benefit of students. The students' involvements in the discussion are essential. A national forum for postgraduates has to be formed, promoting their participation and publications.

There is rapidly accumulating literature regarding the hypercoagulable state associated with patients diagnosed with COVID-19 infection. Pulmonary, cardiac, and visceral involvement has been described. We describe a middle-aged male, with a background of diabetes and hypertension, diagnosed with severe COVID-19, who passed away despite maximum support. He had concomitant aortic and pulmonary thrombus. This is a devastating, poorly understood complication of severe COVID-19, adding to the body of medical literature related to severe COVID-19. COVID-19 is a hypercoagulable disease, and multi-organ involvement should be considered. Aortic imaging during a computed tomography pulmonary angiography can add additional information to the risk stratification and clinical implications in a patient diagnosed with COVID-19, with a suspected hypercoagulable state and possible multi-organ involvement.
