A distant city: Assessing the impact of Dutch socioeconomic developments on urban and rural health using respiratory disease as a proxy.

Objectives: To investigate the prevalence of respiratory disease in several populations from the Netherlands across different time periods and socioeconomic conditions.

Materials: We analyzed 695 adult individuals from six different Dutch contexts of urban and rural settlements dating to different time periods (i.e.

Ancient dental calculus preserves signatures of biofilm succession and interindividual variation independent of dental pathology.

Dental calculus preserves oral microbes, enabling comparative studies of the oral microbiome and health through time. However, small sample sizes and limited dental health metadata have hindered health-focused investigations to date. Here, we investigate the relationship between tobacco pipe smoking and dental calculus microbiomes.

Isotopic reconstruction of short to absent breastfeeding in a 19th century rural Dutch community.

Artificial feeding of young infants is considered a modern phenomenon. However, historical sources note its practice in some past European populations. This research explores factors that contributed to a short to absent period of breastfeeding in pre-modern Netherlands.

Quantifying cortical bone in fragmentary archeological second metacarpals.

Objectives: Skeletal variation in cortical bone thickness is an indicator of bone quality and health in archeological populations. Second metacarpal radiogrammetry, which measures cortical thickness at the shaft midpoint, is traditionally used to evaluate bone loss in bioarcheological and some clinical contexts. However fragmentary elements are regularly omitted because the midpoint cannot be determined.

Coming of age in the Netherlands: An osteological assessment of puberty in a rural Dutch post-medieval community.

Objectives: The objective of this study is to apply pubertal stage estimation methods to a sample from a rural community: the post-medieval Dutch skeletal collection from Middenbeemster. Puberty is a key developmental period involving transition to physical adulthood with broad societal relevance through its impact on fertility, morbidity, and mortality.

Materials And Methods: Individuals (n = 55), including 27 of known sex and age-at-death, between the ages of 8 and 25 years were assessed for six skeletal markers indicative of pubertal growth spurt.

Getting Rid of Dichotomous Sex Estimations: Why Logistic Regression Should be Preferred Over Discriminant Function Analysis.

Sex estimation is an important part of creating a biological profile for skeletal remains in forensics. The commonly used methods for developing sex estimation equations are discriminant function analysis (DFA) and logistic regression (LogR). LogR equations provide a probability of the predicted sex, while DFA relies on cutoff points to segregate males and females, resulting in a rigid dichotomization of the sexes.

Genomic insights into the early peopling of the Caribbean.

The Caribbean was one of the last regions of the Americas to be settled by humans, but where they came from and how and when they reached the islands remain unclear. We generated genome-wide data for 93 ancient Caribbean islanders dating between 3200 and 400 calibrated years before the present and found evidence of at least three separate dispersals into the region, including two early dispersals into the Western Caribbean, one of which seems connected to radiation events in North America. This was followed by a later expansion from South America.

Micro-CT assessment of dental mineralization defects indicative of vitamin D deficiency in two 17th-19th century Dutch communities.

Objectives: This study investigates vitamin D deficiency patterns in individuals from birth to the beginning of adolescence. Microscopic computed tomography (micro-CT) evaluation of interglobular dentine (IGD) in teeth provides information on the age of disease onset and the number of deficient periods per individual, which will increase our understanding of factors influencing vitamin D deficiency prevalence, including sociocultural practices and latitude.

Materials And Methods: Beemster and Hattem, two Dutch 17th-19th century communities, yielded relatively high prevalences of rickets (15-24%) and residual rickets (15-24%).

The efficacy of whole human genome capture on ancient dental calculus and dentin.

Objectives: Dental calculus is among the richest known sources of ancient DNA in the archaeological record. Although most DNA within calculus is microbial, it has been shown to contain sufficient human DNA for the targeted retrieval of whole mitochondrial genomes. Here, we explore whether calculus is also a viable substrate for whole human genome recovery using targeted enrichment techniques.

Gender-related vitamin D deficiency in a Dutch 19th century farming community.

The most common cause of vitamin D deficiency is inadequate dermal exposure to sunlight. Residual rickets is nonadult vitamin D deficiency still evident in an adult individual, whereas osteomalacia occurs in adulthood. Previous research on the Beemster population, a 19th century rural community in the Netherlands, identified rickets in 30.

Columbus' environmental impact in the New World: Land use change in the Yaque River valley, Dominican Republic.

Columbus' arrival in the New World in AD 1492 on the northern coast of Hispaniola was followed by a suite of changes in land-use. We reconstruct environmental change from a 225-cm-long sediment core from site Los Indios from an abandoned and sediment-filled meander of the Yaque River, Cibao Valley, northeastern Dominican Republic. The sediment record starts ca.

A probable case of metastatic carcinoma in the medieval Netherlands.

Despite recent considerable gains, our knowledge of cancer in antiquity is still limited. This paper discusses an adult individual from a Dutch medieval hospital site who demonstrates osteoblastic and osteolytic lesions on the ribs, scapula, clavicle, and vertebrae. The morphology, radiographic appearance, and distribution of the skeletal lesions suggest that this individual was affected by metastatic carcinoma.

Trabecular bone microarchitecture analysis, a way for an early detection of genetic dwarfism? Case study of a dwarf mother's offspring.

A 66 year-old woman with a disproportionate dwarfism and who bore seven children was discovered at the Middenbeemster archaeological site (The Netherlands). Three are perinates and show no macroscopic or radiological evidence for a FGFR3 mutation causing hypo-or achondroplasia. This mutation induces dysfunction of the growth cartilage, leading to abnormalities in the development of trabecular bone.

Origins and genetic legacies of the Caribbean Taino.

The Caribbean was one of the last parts of the Americas to be settled by humans, but how and when the islands were first occupied remains a matter of debate. Ancient DNA can help answering these questions, but the work has been hampered by poor DNA preservation. We report the genome sequence of a 1,000-year-old Lucayan Taino individual recovered from the site of Preacher's Cave in the Bahamas.

Osteochondritis Dissecans of skeletal elements of the foot in a 19th century rural farming community from The Netherlands.

Osteochondritis Dissecans (OD) is a pathological condition of the subchondral bone and surrounding cartilage of synovial joints, associated with strenuous activity and/or trauma. Reports of OD in archaeological skeletal remains are few and the majority demonstrate low OD prevalence (<1%). A predominantly 19th century skeletal sample from Middenbeemster, the Netherlands, was assessed for OD.

Intrinsic challenges in ancient microbiome reconstruction using 16S rRNA gene amplification.

To date, characterization of ancient oral (dental calculus) and gut (coprolite) microbiota has been primarily accomplished through a metataxonomic approach involving targeted amplification of one or more variable regions in the 16S rRNA gene. Specifically, the V3 region (E. coli 341-534) of this gene has been suggested as an excellent candidate for ancient DNA amplification and microbial community reconstruction.

Unexpected evolutionary diversity in a recently extinct Caribbean mammal radiation.

Identifying general patterns of colonization and radiation in island faunas is often hindered by past human-caused extinctions. The insular Caribbean is one of the only complex oceanic-type island systems colonized by land mammals, but has witnessed the globally highest level of mammalian extinction during the Holocene. Using ancient DNA analysis, we reconstruct the evolutionary history of one of the Caribbean's now-extinct major mammal groups, the insular radiation of oryzomyine rice rats.

Osteological evidence of short-limbed dwarfism in a nineteenth century Dutch family: Achondroplasia or hypochondroplasia.

An opportunity to explore osteological features of a form of disproportionate dwarfism is presented by a recent archaeological discovery. Excavation of a predominately nineteenth century Dutch cemetery from the rural, agricultural village of Middenbeemster revealed an older adult female with skeletal changes consistent with achondroplasia. The most marked features are a rhizomelic pattern of shortened and thickened upper and lower limbs, frontal bossing and a moderately depressed nasal bridge, small lumbar neural canals with short pedicles, bowing of the femora and tibiae, and short stature (130.
