Tooth Retention

While the population of the United States increases from 250 to 310 million people, the number in older age groups will increase dramatically from 28 million to about 64 million. Tooth retention has improved remarkably in the 65-74 age groups, from 7.4 in 1962 to 17.9 in 1986. While younger age groups will require less treatment due to decline in dental caries, older age groups appear to require more treatment than did similar age cohorts in previous generations. Hence, the need for restorative procedures by the United States population will be on an upward trend for the next decade or two.

A large national sample of adults ages 18–60 was surveyed on features proposed in the theory of emerging adulthood, including identity explorations, self-focus, feeling in-between, instability, and possibilities/optimism. Additional items were included on feeling that this time of life is a time of freedom and a time that is fun and exciting and on feelings of anxiety and depression. Emerging adults (ages 18–25) were more likely to endorse nearly all the items proposed in the theory of emerging adulthood, yet a surprisingly high proportion of adults in the older age groups (26–29, 30–39, and 40–60) also agreed that the items apply to their current time of life. Thus, the results indicate that the features proposed in the theory of emerging adulthood are more likely to be found among 18- to 25-year-olds than among people in older age groups, but they may not be as distinctive to emerging adulthood as the theory predicted.

Novel Coronavirus

Since the discovery of the novel coronavirus (SARS-CoV-2), COVID-19 has become a global healthcare and economic crisis. The United States (US) and Europe exhibited wide impacts from the virus with more than six million cases by the time of our analysis. To inhibit spread, stay-at-home orders and other non-pharmaceutical interventions (NPIs) were instituted. Beginning late April 2020, some US states, European, and Asian countries lifted restrictions and started the reopening phases. In this study, the changes of confirmed cases, hospitalizations, and deaths were analyzed after reopening for 11 countries and 40 US states using an interrupted time series analysis. Additionally, the distribution of these categories was further analyzed by age due to the known increased risk in elderly patients. Reopening had varied effects on COVID-19 cases depending on the region. Recent increases in cases did not fully translate into increased deaths. Eight countries had increased cases after reopening while only two countries showed the same trend in deaths. In the US, 30 states had observed increases in cases while only seven observed increased deaths. In addition, we found that states with later reopening dates were more likely to have significant decreases in cases, hospitalizations, and deaths. Furthermore, age distributions through time were analyzed in relation to COVID-19 in the US. Younger age groups typically had an increased share of cases after reopening.

Abstract Background Benign meningiomas are the most frequently reported central nervous system tumors in the United States (US), with increasing incidence in past decades. However, the future trajectory of this neoplasm remains unclear. Methods We analyzed benign meningioma incidence of cases identified by any means (eg, radiographically with or without microscopic confirmation) in US Surveillance Epidemiology and End Results (SEER) cancer registries among 35–84-year-olds during 2004–2017 by sex and race/ethnicity using age-period-cohort (APC) models. We employed APC forecasting models to glean insights regarding the etiology, distribution, and anticipated future (2018–2027) public health impact of this neoplasm. Results In all groups, meningioma incidence overall increased through 2010, then stabilized. Temporal declines were statistically significant overall and in most groups. JoinPoint analysis of cohort rate-ratios identified substantial acceleration in White men born after 1963 (from 1.1% to 3.2% per birth year); cohort rate-ratios were stable or increasing in all groups and all birth cohorts. We forecast that meningioma incidence through 2027 will remain stable or decrease among 55–84-year-olds but remain similar to current levels among 35–54-year-olds. Total meningioma burden in 2027 is expected to be approximately 30,470 cases, similar to the expected case count of 27,830 in 2018. Conclusions Between 2004–2017, overall incidence of benign meningioma increased and then stabilized or declined. For 2018–2027, our forecast is incidence will remain generally stable in younger age groups but decrease in older age groups. Nonetheless, the total future burden will remain similar to current levels because the population is aging.
