Impact of the COVID-19 Pandemic on ST-Elevation Myocardial Infarction Management in Hunan Province, China: A Multi-Center Observational Study

Effects of public health interventions and zero COVID policy on paediatric diseases: A Southern China study

Background

With the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic in schools and communities, clinical evidence is needed to determine the impact of the pandemic and public health interventions under the zero coronavirus disease policy on the occurrence of common infectious diseases and non-infectious diseases among children.

Methods

The current study was designed to analyse the occurrence of common infectious diseases before and after the pandemic outbreak in southern China. Data was obtained for 1 801 728 patients admitted into children's hospitals in Guangzhou between January 2017 and July 2022. Regression analysis was performed for data analysis.

Results

The annual occurrence of common paediatric infectious diseases remarkably decreased after the pandemic compared to the baseline before the pandemic and the monthly occurrence. Cases per month of common paediatric infectious diseases were significantly lower in five periods during the local outbreak when enhanced public health measures were in place. Cases of acute non-infectious diseases such as bone fractures were not reduced. Non-pharmaceutical interventions decreased annual and monthly cases of paediatric respiratory and intestinal infections during the coronavirus disease 2019 (COVID-19) pandemic, especially when enhanced public health interventions were in place.

Conclusions

Our findings provide clinical evidence that public health interventions under the dynamic zero COVID policy in the past three years had significant impacts on the occurrence of common respiratory and intestinal infectious diseases among children and adolescents but little impact on reducing non-infectious diseases such as leukaemia and bone fracture.

ST-Segment Elevation Myocardial Infarction (STEMI) Management in the Era of COVID-19: A Systematic and Critical Review of Published Guidance Reports

Background

Coronavirus disease 2019 (COVID-19) had a major impact on healthcare systems worldwide. During the early phase of the pandemic many elective procedures were postponed. At the same time, the safe and effective management of medical emergencies such as ST-segment elevation myocardial infarction (STEMI) has been a challenge.

Methods

A systematic literature search was conducted aiming to identify published guidance reports by national or international societies regarding the management of patients suffering STEMI in the era of COVID-19.

Results

Among 1681 articles initially retrieved, six fulfilled the inclusion criteria and were included in the systematic review. Two reports were international consensus documents, while four reports were national guidance statements from Asian countries (Taiwan, India, Iran, and China). Most documents were drafted during the early phase of the pandemic. According to the international consensus documents, percutaneous coronary intervention (PCI) should be regarded as the reperfusion method of choice. On the other hand, in three out of four national consensus statements (Taiwan, Iran and China) fibrinolysis was considered as the reperfusion method of choice for STEMI in suspected/confirmed patients with COVID-19, unless contraindicated or in the presence of high cardiovascular risk clinical features. Authors of all documents underlined the need for early COVID-19 testing in patients with STEMI to better determine the next therapeutical steps.

Conclusions

National and international consensus statements for STEMI management in the era of COVID-19 have been published mainly during the early peak phase of the pandemic. Authors recognise that these recommendations are mainly based on expert opinions and observational data. As global immunization rates increase and methods for rapid COVID-19 detection are widely available, the implementation of traditional evidence-based practices used before the pandemic is becoming more feasible.
