Bushfires,Human Health Economics,and Pyrogeography

Bushfires (landscape fires) are a key Earth system process that affects humans and our societies and economies. In a recent article, we explored the coupling of humans to landscape fire through the lens of human health impacts of bushfire smoke. We noted that such an approach demands recognition of the indirect impacts and costs of bushfires that cannot be captured by simplistic proxies such as deaths directly attributable to a fire front. Evaluation of direct and indirect economic costs of bushfire disasters, and bushfire fire management remains a poorly developed research frontier that demands collaboration of expertise from a broad cross‐section of fields that often have limited experience of collaborating together. The need for such synthetic thinking about fire's place on Earth has spawned the discipline of pyrogeography.     

Recording dental caries in archaeological human remains

Dental caries is an important condition to record in archaeological collections, but the way in which recording is carried out has a large effect on the way in which the results can be interpreted. In living populations, dental caries is a disease that shows a strong relationship with age. Both the nature of carious lesions and their frequency change with successive age groups from childhood to elderly adulthood. There is also a progression in the particular teeth in the dentition which are most commonly affected and, in general, the molars and premolars are involved much more frequently than the canines and incisors. Lower teeth are usually affected more than upper, although the condition usually involves the right and left sides fairly equally. In the high tooth wear rate populations represented by many archaeological and museum collections, there is a complex relationship between the form of lesions and the state of wear, which adds yet another range of factors to the changing pattern of caries with increasing age. In the same populations, chipping, fracture and anomalous abrasion of teeth are also common, and these contribute similarly to the distribution and forms of carious lesion observed. Amongst the living, the pattern of ante‐mortem tooth loss is important in understanding caries and, in archaeological material, there is also the complicating factor of post‐mortem tooth loss. Finally, there is the question of diagnosis. There are diagnostic problems even in epidemiological studies of living patients and, for archaeological specimens, diagenetic change and the variable preservation of different parts of the dentition add further complications. For all these reasons, it is difficult to define any one general index of dental caries to represent the complete dentition of each individual, which would be universally suitable for studying a full range of collections from archaeological sites or museums. Variation in the nature of collections, their preservation, tooth wear, and ante‐mortem and post‐mortem tooth loss mean that when such a general index appears to differ between sites, there could be many other reasons for this, in addition to any genuine differences in caries incidence and pattern that might have been present. It is suggested here that the best approach is instead to make comparisons separately for each tooth type, age group, sex, lesion type and potential lesion site on the tooth.

Collecting,Collections, and Practice in the Anthropologies of Health and Disease

Anthropologists studying health and disease collect data ranging from human remains to peoples’ lived experiences. Each of the books reviewed here reveals the social processes that shape how disease phenomena are observed, assessed, classified, and interpreted, both by the individuals who experience them and the researchers who study them. The classic anthropological themes of collection, exchange, circulation, social relations, and reciprocity resonate throughout. Theoretical and methodological differences aside, anthropologists remain united by a commitment to holistic and integrative approaches and the shared goal of providing historically and socially contextualized, nuanced understandings of the human condition.     

Distribution of dental caries in an early 17th century swedish population with special reference to diet

The distribution of dental caries was determined in complete and partial human dentitions from a 17th century (1621–1640) city graveyard excavated in Gothenburg, Sweden. Sixty‐three adults and two children, divided into five different age groups, were studied. Altogether 949 teeth (943 permanent and six deciduous) were examined macroscopically using a dental probe and X‐rays. A high number of teeth had been lost post‐mortem. An increase in ante‐mortem tooth loss was found with increasing age. Sixty per cent of all individuals and 12% of all teeth showed signs of caries. The number of carious teeth per subject increased with increasing age. The highest prevalence of individuals with caries was found for the age group 26–35 (69%). Caries were most prevalent in the first, second and third lower molars (60%), while the incisors and canines in the upper and lower jaws were the least affected teeth (1%). The occlusal surface was the area most susceptible to caries (45%), followed by the buccal cemento–enamel junction (16%) and the approximal contact point (11%). This study shows that, although consuming a diet believed to have been lower in sugar content compared to modern populations, caries did affect a rather high number of individuals living in Sweden during the early 17th century.

A Global Journey – Ancel Keys,the FAO,and the Rise of Transnational Heart Disease Epidemiology, 1949–1958

Few people have influenced western eating patterns in the twentieth and early twenty-first centuries as much as physiologist and epidemiologist Ancel Keys (1904–2004). Keys not only developed the K Ration for the United States military, but also advocated for diets that lowered blood cholesterol and famously discovered the health benefits of the Mediterranean diet in the 1950s and 1960s. Keys’ interest in the Mediterranean diet arose from his service on the United Nations (UN) Food and Agriculture Organization (FAO)-World Health Organization (WHO) Joint Expert Committee on Nutrition, which allowed him to explore nutritional status, dietary habits, and regional eating patterns across the globe. This paper examines how Keys’ service as chair of the UN FAO Committee on Caloric Requirements and the UN FAO Expert Committee on Nutrition led him to think globally about the relationship between diet and cardiovascular health, and to launch the first international comparative epidemiological study of diet and heart disease, the Seven Countries Study.     

Apparent and actual disease landscapes. Some reflections on the geographical definition of health and disease

Like geographical analysis in general, medical geography is based on the assumption that location is the first clue to causal analysis. Against a background of two empirical studies, one dealing with a group of ALS cases and the other with a group of leukaemia cases, this paper argues that it is insufficient to define disease occurrence in spatial terms, referring to patients' places of residence at the time of onset. Since exposure and effect are related to both time and place, geographical studies of ill health in modern society are complicated by high mobility, long periods of latency and environmental change which might cause a distortion between cause and effect. Therefore a different approach is required.     

Prevalence rates of spondylolysis in British skeletal populations

As an activity‐related pathological lesion, spondylolysis and its prevalence rates are indicative of relative diachronic activity levels in different populations. In this paper we document the prevalence of spondylolytic defects in a series of time‐successive populations with special reference to the recording methods employed, and compare the findings with modern clinical studies. We identify epidemiological trends in expression of the condition through 1500 years in a series of skeletonised human remains from England. This includes a 5th–6th‐century settlement, a 15th‐century mass grave, a 14th to 17th‐century rural parish, a medieval Dominican friary, a medieval leper hospital and an 18th to 19th‐century crypt collection. These skeletal populations sample human groups experiencing considerable social change from an agrarian, non‐centralised early medieval period through the development of the medieval state to the earliest phases of industrialisation in England. A detailed study of all lumbar vertebrae in one of the assemblages highlights discrepancies between clinical prevalence rates for spondylolysis established through radiography, and those resulting from direct osteological analysis of the lumbar region of the vertebral column. Current prevalence rates cited in the osteological as well as the clinical literature are greatly dependent upon the recording methods employed, and the effects of several methods for osteological remains are considered in this treatment. For the populations reported on here, prevalence rates vary from considerably less than 1% to as much as 12%, depending on the method selected. A standardised recording method for spondylolytic lesions is suggested to facilitate accurate prevalence reporting and comparison of activity levels between different populations.

Multiple myeloma in an early medieval skeleton

Detailed studies on neoplasms in prehistoric populations are rare. Each well-documented case can therefore add to our knowledge. In former times, palaeopathology could present only tentative diagnoses in the case of tumours. Today, modern diagnostic methods and a comparison with established cases make exact evaluations and their verification possible. During our study it became obvious that criteria for the diagnosis of recent tumours can be used as a guide. In this paper we present the most important findings of a malignant primary bone tumour (multiple myeloma) in an early medieval skeleton and its differential diagnoses. Even in the absence of histological findings, the remaining criteria (X-ray, age, localization, macroscopic features) permit the diagnosis of multiple myeloma to be made with some certainty.     

The Black Death

The purpose of the present research is to examine various theories concerning the origin of the Black Death, to record its routes of dissemination in the Nordic countries and across the British Isles, and to compare the pattern of that dissemination with trade routes carrying grain throughout northern Europe in the period up to and including 1350.
