The Epidemiologic Transition can help us understand a fundamental puzzle about aging. The puzzle stems from two seemingly contradictory facts. The first fact is that death rates from noninfectious degenerative maladies – the so-called diseases of aging – increase as people age. It seems to be at odds with the historical fact that for nearly a century in which people were aging more than ever before, the aggregate rates of such diseases have been decreasing. In what sense can both be true? Crucial to resolving the puzzle are the age-profiles of such diseases in cohorts that grew up in the different regimes of the Transition. For each cohort, noninfectious diseases had increased with age, resulting in an upward-sloping age profile, which affirms the first fact. As the regimes were transitioning from the Malthusian to the modern one, however, the profiles of successive cohorts had been shifting downward: death rates from noninfectious diseases were shrinking at each age, signifying the newer cohorts’ greater aging potentials. The shifting profiles had been renewing the cohort mix of the population, shaping the century-long descent of such diseases in aggregate, giving rise to the historical fact. The profiles had shifted early in the cohorts’ adult years, associating closely with the newer epidemiologic conditions in childhood. Those conditions appear to be a circumstance under which aging potentials of cohorts could be misgauged, including in one troubling episode in the first half of the nineteenth century when the potentials had reversed.

Epidemiology is often described as “the basic science of public health” (Savitz, Poole & Miller, 1999; Syme & Yen, 2000). This description suggests both a close association with public health practice, and the separation of “pure” scientific knowledge from its application in the messy social world. Although the attainability of absolute objectivity is rarely claimed, epidemiologists are routinely encouraged to “persist in their efforts to substitute evidence for faith in scientific reasoning” (Stolley, 1985, p. 38) and reminded that “public health decision makers gain little from impassioned scholars who go beyond advancing and explaining the science to promoting a specific public health agenda” (Savitz et al., 1999, p. 1160). Epidemiology produces authoritative data that are transformed into evidence which informs public health. Those data are authoritative because epidemiology is regarded as a neutral scientific enterprise. Because its claims are grounded in science, epidemiological knowledge is deemed to have “a special technical status and hence is not contestable in the same way as are say, religion or ethics” (Lock, 1988, p. 6). Despite the veneer of universality afforded by its scientific pedigree, epidemiology is not a static or monolithic discipline. Epidemiological truth claims are embodied in several shifting paradigms that span the life of the discipline. Public health knowledges and practices, competing claims internal and external to epidemiology, and structural conditions (such as current political economies, material technologies, and institutions) provide important contexts in which certain kinds of epidemiological knowledge are more likely to emerge.

In the context of US kidney disease care in 2020, this chapter highlights challenges of managing COVID-19–related acute pathology, sustaining safe chronic dialysis treatment for individuals with kidney failure during a pandemic, and identifying ways to effectively address intersections of race/ethnicity, SES, and health.

Medical literature and American Society of Nephrology (ASN) online member forum review, and Emory School of Medicine Renal Grand Rounds participant observation: April 2020–March 2021.

Among persons infected with COVID-19, especially persons of African descent, acute kidney injury (AKI) risk was elevated and associated with need for long-term dialysis. Dialysis-dependent chronic kidney disease patients constituted a high-risk group for COVID-19 infection and hospitalization, due to underlying chronic conditions as well as required travel to clinics for multiple weekly dialysis treatments with exposure to possibly infected staff and other patients.

Findings that are discussed are based on a limited time frame. The longer-term impact of COVID-19 for patient outcomes and for the structure of kidney disease care is a fertile area for continued study, especially in relation to broad health equity goals.

Racial justice activism in 2020 highlighted the imperative to address socioeconomic and racially structured inequities in the United States, and health equity goals and strategies that target kidney disease care have been outlined. The acute/chronic continuum of kidney disease care is a fertile area for research that is informed by the COVID-19 experience and population health inequity challenges.

This paper aims to introduce an under-researched concept, travel medicine, to the hospitality field and proposes future research directions. This paper also highlights the need to acknowledge the missing link between hospitality and medical science and encourages research on the health of hotel guests, especially those with mental disorders.

By synthesizing relevant literature, this study proposes a conceptual framework focused on identifying and filling knowledge gaps between hospitality and medical science. Pathways for empirical research on hotel guests’ travel health are suggested accordingly.

This paper reveals that the topic of travel medicine has been neglected in hospitality, especially in relation to vulnerable hotel guests. Additionally, this study suggests that researchers should move beyond the confines of social science and conduct interdisciplinary hospitality studies. In-depth analyses of hotel guests’ health and safety are also recommended.

This conceptual piece serves as a “provocation” that is exploratory, thus laying a foundation for future interdisciplinary studies bridging hospitality and medical science. This paper offers practical significance for hospitality stakeholders (i.e. academics, practitioners, hotel guests and society) and also provides guidelines on how to create vulnerability-friendly hospitality environments.

To the best of the authors’ knowledge, this study takes an important step toward interdisciplinary research between hospitality and medical science through the lens of travel medicine. This paper offers insight to bridge these disciplines and extend hospitality research into medical science. This paper further identifies an under-investigated topic and feasible research avenues that can offer timely solutions for hospitality academics and practitioners.

The influx of refugees and asylum-seekers over the past decade into the European Union creates challenges to the health systems of receiving countries in the preparedness and requisite adjustments to policy addressing the new needs of the migrant population. This study aims to examine and compare policies for access to health care and the related health outcomes for refugees and asylum-seekers settling both in the UK and Germany as host countries.

The paper conducted a scoping review of academic databases and grey literature for studies within the period 2010-2017, seeking to identify evidence from current policies and service provision for refugees and asylum-seekers in Germany and the UK, distilling the best practice and clarifying gaps in knowledge, to determine implications for policy.

Analysis reveals that legal entitlements for refugees and asylum-seekers allow access to primary and secondary health care free of charge in the UK versus a more restrictive policy of access limited to acute and emergency care during the first 15 months of resettlements in Germany. In both countries, many factors hinder the access of this group to normal health care from legal status, procedural hurdles and lingual and cultural barriers. Refugees and asylum-seeker populations were reported with poor general health condition, lower rates of utilization of health services and noticeable reliance on non-governmental organizations.

This paper helps to fulfill the need for an extensive research required to help decision makers in host countries to adjust health systems towards reducing health disparities and inequalities among refugees and asylum-seekers.

Building a culture of safety in transportation is not dissimilar from building a culture of safety in health. Public health is widely known for protecting the public from diseases through milk pasteurization and chlorination of drinking water, and from injuries by implementing environmental and occupational safeguards and fostering behavioral change. Lifestyle and environmental changes that have contributed to the reductions in smoking and heart disease can also help change driving, walking and cycling behaviors, and environments. Stimulating a culture of safety on the road means providing safe and accessible transportation for all. The vision for a culture of traffic safety is to change the public’s attitude about the unacceptable toll from traffic injuries and to implement a systems approach to traffic injury prevention as a means for improving public health and public safety. Framing the motor vehicle injury problem in this way provides an opportunity for partnerships between highway safety and public health to improve the culture of safety.

Our objective was to compare the physical health status of adult prisoners with and without a mental illness. Mental illness was diagnosed in a sample of 557 Australian prisoners using the Composite International Diagnostic Interview (CIDI). Physical health measures included self‐reported chronic health conditions, recent health complaints and symptoms, self‐assessed health using the Short‐Form 36 Health Survey (SF‐36), and markers of infectious diseases known to be highly prevalent among prisoner populations (hepatitis A, hepatitis B, and hepatitis C). Men and women with a mental illness had lower scores on the SF‐36 compared with those without a mental illness indicating poor overall health. Adjusting for age and sex, a diagnosis of any mental illness (symptoms of psychosis, anxiety or affective disorder) was positively associated with a history of head injury, back problems, asthma, peptic ulcers, cancer, and epilepsy/seizures. There was a significant association between post traumatic stress disorder and asthma, a history of head injury, peptic ulcers, and cancer. There was no significant difference in the proportion of current tobacco smokers in the mentally ill and nonmentally ill groups (81% vs. 77%, p = 0.33). However, those with a mental illness were less likely than those with no diagnosis to exercise in the past 4 weeks (79% vs. 89%, p = 0.002). Mentally ill prisoners also have significant physical co‐morbidity compared with the non‐mentally ill. These findings suggest that those providing mental health services to prisoners should adopt a holistic approach embracing both mental and physical health.
