As a global pandemic is inevitable, real-time monitoring of transmission is vital for containing the spread of COVID-19. The main objective was to report real-time effective reproduction numbers (R(t)) case fatality rate (CFR). Data were mainly obtained from WHO website, up to 9 March 2020. R(t) was estimated by exponential growth rate (EG) and time dependent (TD) methods. "R0" package in R was employed to estimate R(t) by fitting the existing epidemic curve. Both naïve CFR (nCFR) and adjust CFR (aCFR) were estimated. In EG method, R(t) was 3.27 [3.17-3.38] for Italy, 6.32 [5.72-6.99] for France, 6.07 [5.51-6.69] for Germany, 5.08 [4.51-5.74] for Spain. With TD method, the R value for March 9 was 3.10 [2.21-4.11] for Italy, 6.56 [2.04-12.26] for France, 4.43 [1.83-7.92] for Germany, and 3.95 [0-10.19] for Spain. This study provides important findings on an early outbreak of COVID-19 in Europe. Due to the recent rapid increase in new cases of COVID-19, real-time monitoring of the transmissibility and mortality in Spain and France is a priority.

To cope with the increasing healthcare costs brought about by the universal health insurance programme, national volume-based procurement (NVBP) was implemented in China to reduce drug prices. However, the impact of NVBP remains unknown. We reported the effects of the NVBP pilot programme on medication affordability and discussed the challenges and recommendations for further reforms. A total of 25 molecules won the bidding in the NVBP pilot programme, and price cuts ranged from 25% to 96%. Medication affordability was measured as the number of days’ wages needed to pay for a course of treatment, and the medication was identified as affordable if the cost of a treatment course was less than the average daily wage. After the NVBP, the proportion of affordable drugs increased from 33% to 67%, and the mean affordability improved from 8.2 days’ wages to 2.8 days’ wages. Specifically, for rural residents, the proportion of affordable drugs increased from 13% to 58%, and the mean affordability improved from 15.7 days’ wages to 5.3 days’ wages. For urban residents, the proportion of affordable drugs increased from 54% to 71%, and the mean affordability improved from 5.9 days’ wages to 2.0 days’ wages. Implementing the NVBP substantially improved medication affordability. In future reforms, a multifaceted approach addressing all issues in the health system is needed to enhance medicine access.

Background: Two coronavirus disease 2019 (COVID-19) vaccines have received emergency use authorizations in the U.S. However, the safety of these vaccines in the real-world remains unknown.Methods: We reviewed adverse events (AEs) following COVID-19 vaccination among adults in the Vaccine Adverse Event Reporting System (VAERS) from December 14, 2020, through January 22, 2021. We compared the top 10 AEs, serious AEs, along with office and emergency room (ER) visits by age (18–64 years, ≥65 years) and gender (female, male).Results: There were age and gender disparities among adults with AEs following COVID-19 vaccination. Compared to younger adults aged between 18 and 64 years, older adults were more likely to report serious AEs, death, permanent disability, and hospitalization. Males were more likely to report serious AEs, death, and hospitalization compared to females.Conclusions: COVID-19 vaccines are generally safe but possible age and gender disparities in reported AEs may exist.

An increasing number of myocarditis/pericarditis incidences has been reported after coronavirus disease-19 (COVID-19) vaccination in adolescents and young adults. This study was designed to investigate the incidence rate of—and risk for—myocarditis and pericarditis following COVID-19 vaccination in the United States according to age and vaccine type. This study used the Vaccine Adverse Events Reporting System (VAERS) from 11 December 2020 to 13 August 2021. A population-based data mining approach was performed based on the reporting odds ratio (ROR). Adverse events of myocarditis and pericarditis following COVID-19 vaccination were rare, with an incidence rate of 5.98 (95% CI = 5.73–6.24) cases per million doses administered. The incidence rate was higher in adolescents and after the administration of the second dose of messenger RNA (mRNA) vaccines. Overall, two mRNA vaccines were significantly associated with increased risks for myocarditis/pericarditis (mRNA-1273 (Moderna): ROR = 2.91, 95% CI = 2.21–3.83; BNT162b2 (Pfizer–BioNTech): ROR = 5.37, 95% CI = 4.10–7.04) compared to all other vaccines from VAERS. The viral vector vaccine of Ad26.COV2.S (Janssen) was not associated with signals of myocarditis/pericarditis (ROR = 1.39; 95% CI = 0.99–1.97). This study found increased risks for myocarditis/pericarditis following mRNA COVID-19 vaccines. For patients at high risk for myocarditis/pericarditis or with myocardial injuries, the viral vector vaccine may be an alternative for consideration.

Objective To study the impact of financial barriers to healthcare on health status, healthcare utilisation and costs among patients with cognitive impairment. Design Cross-sectional. Setting National Health Interview Survey (NHIS), 2011–2017. Participants Patients with cognitive impairment aged 18 years or older. Interventions Financial barriers to healthcare were identified using a series of NHIS prompts asking about the affordability of healthcare services. Primary outcome measures Health status was based on a survey prompt about respondents’ general health. Healthcare utilisation included office visits, home healthcare visits, hospital stays and emergency department (ED) visits. Economic burden was based on the family spending on medical care. Logistic regression models were used to examine the impact of financial barriers to healthcare access on health status, home healthcare visits, office visits, hospital stays and ED visits, respectively. Results Compared with cognitively impaired respondents without financial barriers to healthcare access, those with financial barriers were more likely to be unhealthy (OR 0.64, 95% CI 0.57 to 0.72). Cognitively impaired respondents with financial barriers were less likely to have home healthcare (OR 0.69, 95% CI 0.48 to 0.99) and more likely to have hospital stays (OR 1.33, 95% CI 1.19 to 1.48) and ED visits (OR 1.50, 95% CI 1.35 to 1.67). In addition, compared with cognitively impaired respondents without financial barriers to healthcare access, those with the barriers were more likely to have an increased economic burden (OR=1.85, 95% CI 1.65 to 2.07). Conclusion Financial barriers to healthcare worsened health status and increased use of ED, hospitalisation and economic burden. Policy decision-makers, providers and individuals with cognitive impairment should be aware of the impact of financial barriers and take corresponding actions to reduce the impact.

Autism spectrum disorder (ASD) is a developmental disability characterized by repetitive behaviors and persistent impairments in social interaction and communication. The prevalence of ASD has been increasing since 2000, with inconsistent findings in racial/ethnic disparities.1-3 Over the past decade, the racial/ethnic disparities have persisted but have narrowed in response to the US Health and Human Services Action Plan to Reduce Racial and Ethnic Health Disparities.4 However, it remains unknown how racial/ethnic disparities have changed over time. We used recently released data from the National Health Interview Survey to assess the most recent temporal trends and racial/ethnic disparities in ASD prevalence from 2014 through 2019.
