An Insight Into Pathophysiology, Epidemiology, and Management of Cardiovascular Complications of SARS-CoV-2 Infection, Post-acute COVID Syndrome, and COVID Vaccine.

Coronavirus disease 2019 (COVID-19), the disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was declared a pandemic health emergency in March 2020. Elderly patients and those with pre-existing medical conditions including cardiovascular disease are at increased risk of developing severe disease. Not only is the viral infection with SARS-CoV-2 associated with higher mortality in patients with underlying cardiovascular disease, but development of cardiovascular complications is also common in patients with COVID-19. Even after recovery from the acute illness, post-acute COVID syndrome with cardiopulmonary manifestations can occur in some patients. Additionally, there are rare but increasingly recognized adverse events, including cardiovascular side effects, reported with currently available COVID-19 vaccines. In this review, we discuss the most common cardiovascular complications of SARS-CoV-2 and COVID-19 vaccines, cardiopulmonary manifestations of post-acute COVID syndrome and the current evidence-based guidance on the management of such complications.

[The role of advance care planning and palliative care in new york city during COVID-19 pandemic].

New York City faced an explosive spread of Coronavirus disease 2019 (COVID-19), causing the city's death toll to spike owing to the high virulence of COVID-19. The health care system was on the verge of collapse. Advance care planning (ACP), informed assent, and palliative care played significant roles in supporting patient self-determination and dignity, facilitating decision making, and promoting better care. The importance of these strategies was revisited. Learning from the COVID-19 pandemic in New York City, it is anticipated that several approaches such as ACP and palliative intervention may attract more attention and become increasingly essential to the healthcare system in Japan.

Value of leukocytosis and elevated C-reactive protein in predicting severe coronavirus 2019 (COVID-19): A systematic review and meta-analysis.

BACKGROUND: Since December 2019, coronavirus 2019 (COVID-19) has spread worldwide. Identifying poor prognostic factors is helpful for risk stratification. In this meta-analysis, we investigated the association between severe COVID-19 and a change in white blood cell (WBC) count, an elevation of C-reactive protein (CRP), and fever. Moreover, we aimed to evaluate the diagnostic accuracy of leukocytosis and an elevation of CRP. METHODS: We performed a systematic search of PubMed, EMBASE, Scopus, and the Cochrane Library through April 20th, 2020. The odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. A sensitivity analysis was conducted according to the study size (>200 or <200) and median age (>55 or <55). Meta-regression analyses were conducted to examine possible sources of heterogeneity. We calculated the diagnostic accuracy of leukocytosis and CRP. RESULTS: Eighteen studies with 3278 patients were selected. Fever, leukocytosis, and elevated CRP were associated with poor outcomes (OR (95% CI) 1.63 (1.06-2.51), 4.51 (2.53-8.04), and 11.97 (4.97-28.8), respectively). Leukopenia was associated with a better prognosis (OR 0.56, 95% CI 0.40-0.78). Sensitivity analyses showed similar tendencies. Meta-regression analysis for leukocytosis indicated that age, dyspnea, and hypertension contributed to heterogeneity. The pooled area under the leukocytosis and CRP curves were 0.70 (0.64-0.76) and 0.89 (0.80-0.99), respectively. CONCLUSION: In patients with COVID-19, fever, leukocytosis, and an elevated CRP were associated with severe outcomes. Leukocytosis and CRP on arrival may predict poor outcomes.
