Baiano MA, Cerda IA, Bertozzo F, Pol D. New information on paleopathologies in non-avian theropod dinosaurs: a case study on South American abelisaurids. BMC Ecol Evol 2024; 24:6. [PMID: 38291378 PMCID: PMC10829224 DOI: 10.1186/s12862-023-02187-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Accepted: 12/06/2023] [Indexed: 02/01/2024] Open
Abstract
Studies on pathological fossil bones have allowed improving the knowledge of physiology and ecology, and consequently the life history of extinct organisms. Among extinct vertebrates, non-avian dinosaurs have drawn attention in terms of pathological evidence, since a wide array of fossilized lesions and diseases were noticed in these ancient organisms. Here, we evaluate the pathological conditions observed in individuals of different brachyrostran (Theropoda, Abelisauridae) taxa, including Aucasaurus garridoi, Elemgasem nubilus, and Quilmesaurus curriei. For this, we use multiple methodological approaches such as histology and computed tomography, in addition to the macroscopic evaluation. The holotype of Aucasaurus shows several pathognomonic traits of a failure of the vertebral segmentation during development, causing the presence of two fused caudal vertebrae. The occurrence of this condition in Aucasaurus is the first case to be documented so far in non-tetanuran theropods. Regarding the holotype of Elemgasem, the histology of two fused vertebrae shows an intervertebral space between the centra, thus the fusion is limited to the distal rim of the articular surfaces. This pathology is here considered as spondyloarthropathy, the first evidence for a non-tetanuran theropod. The microstructural arrangement of the right tibia of Quilmesaurus shows a marked variation in a portion of the outer cortex, probably due to the presence of the radial fibrolamellar bone tissue. Although similar bone tissue is present in other extinct vertebrates and the cause of its formation is still debated, it could be a response to some kind of pathology. Among non-avian theropods, traumatic injuries are better represented than other maladies (e.g., infection, congenital or metabolic diseases, etc.). These pathologies are recovered mainly among large-sized theropods such as Abelisauridae, Allosauridae, Carcharodontosauridae, and Tyrannosauridae, and distributed principally among axial elements. Statistical tests on the distribution of injuries in these theropod clades show a strong association between taxa-pathologies, body regions-pathologies, and taxa-body regions, suggesting different life styles and behaviours may underlie the frequency of different injuries among theropod taxa.

Vlok M. Technical note: The use and misuse of threshold diagnostic criteria in paleopathology. AMERICAN JOURNAL OF BIOLOGICAL ANTHROPOLOGY 2023; 181:326-335. [PMID: 36866523 DOI: 10.1002/ajpa.24721] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 12/16/2022] [Accepted: 02/19/2023] [Indexed: 03/04/2023]
Abstract
Weighted threshold diagnostic criteria approaches have emerged for diseases that involve skeletal/bony tissue that are readily diagnosed in the field of paleopathology such as Vitamin C deficiency (scurvy), Vitamin D deficiency (rickets) and treponemal disease. These criteria differ from traditional differential diagnosis in that they involve standardized inclusion criteria based on the lesion's specificity to the disease. Here I discuss the limitations and benefits of threshold criteria. I argue that while these criteria will benefit from further revision such as inclusion of lesion severity, and the incorporation of exclusion criteria, threshold diagnostic approaches have considerable value in the future of diagnosis in the field.

INTERNATIONAL JOURNAL OF PALEOPATHOLOGY 2023; 41:8-21. [PMID: 36889217 DOI: 10.1016/j.ijpp.2023.02.002] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Revised: 02/22/2023] [Accepted: 02/22/2023] [Indexed: 06/12/2023]
Abstract
OBJECTIVE Overall, paleopathology trails behind related fields in exploring sex, gender, and sexuality in past societies. Here, we interrogatively synthesize scholarship on topics not included in similar reviews, focusing on sex estimation methods, and considering the social determinants of health; trauma; reproduction and family; and childhood - to highlight novel, social epidemiology- and social theory-informed frameworks and interpretive devices. CONCLUSIONS Many paleopathological interpretations focus on sex-gender differences relative to health, with increasing use of intersectionality. Others consistently project present-day ideologies about sex, gender, and sexuality (e.g., binary sex-gender systems) into paleopathological interpretations (i.e., presentism). SIGNIFICANCE Paleopathologists have an ethical imperative to generate scholarship that contributes to social justice initiatives focused on dismantling structural inequalities, especially relative to sex, gender, and sexuality (e.g., homophobia), such as through denaturalizing presentist binary systems. They also have a responsibility towards greater inclusivity relative to researcher identity and diversification of method and theory. LIMITATIONS In addition to material limitations complicating reconstructions of sex, gender, and sexuality relative to health and disease in the past, this review wasn't comprehensive. The review was also limited by the relative paucity of paleopathological work on these topics. SUGGESTIONS FOR FUTURE RESEARCH The outlook for paleopathological research on sex, gender, and sexuality is, however, positive; paleopathology is well situated to tackle these aspects of social identity. Future work should consider critical, self-reflective movement away from presentism; more robust contextualization; and further engagement with social theory and social epidemiology theory and approaches, including the Developmental Origins of Health and Disease (DOHaD), social determinants of health, and intersectionality.

Abstract
OBJECTIVE To critically examine the role that case studies play in recent paleopathological literature, by evaluating their frequency of publication, academic impact, and the public engagement they generate. MATERIALS Articles published in International Journal of Paleopathology between 2011 and 2018 (N = 377). METHODS Articles were coded as case studies, population studies, methodological studies, or reviews. Case studies were coded as cultural practices, differential diagnosis, historical, or methodological/theoretical. We utilized bibliometric analysis to assess academic impact and altmetric analysis to evaluate public engagement. RESULTS Case studies continue to be the most frequently published, but least frequently cited, article type. There are no significant differences in public engagement data between article types. Methodological/theoretical case studies have the most academic impact. Differential diagnosis case studies have the least academic impact and generate the least public engagement. CONCLUSIONS The case study genre includes a variety of approaches, some of which hold significant potential for contributing to the discipline of paleopathology and beyond. SIGNIFICANCE This study updates Mays' (2012b) citation analysis, pioneers the use of altmetric data to analyze public engagement with paleopathological publications, and identifies less productive approaches and areas of heightened relevance in the case study genre. LIMITATIONS Publications in only one journal were analyzed. Only one source was utilized for citation data (Google Scholar) and one source for altmetric data (PlumX). SUGGESTIONS FOR FUTURE RESEARCH Expanding the granular analysis of case studies piloted here to additional journals and/or citation indexes to enlarge the sample size and provide keener insights.

Abstract
Suchey-Brooks method has been studied many times with varying reports of accuracy and reliability. A systematic review and meta-analyses were utilized to quantitatively determine the accuracy and reliability of the Suchey-Brooks (S-B) method. A systematic search of PubMed and EBSCO health and medical databases was performed. Meta-analyses were performed to quantify the relationship between actual known age at death and the S-B method using Spearman's Rho and Pearson's r for (1) combined males and females estimates, (2) male-only estimates, and (3) female-only estimates. Overall correlation coefficient using Cohen's kappa, Spearman's Rho, and Pearson's r was also calculated to determine the interrater and intrarater reliability using the S-B method. Eighteen studies classified as moderate-to-high methodological quality met the inclusion criteria. The sample sizes were different for the combined male and female (n = 2620), male-only (n = 2602), and female-only (n = 1431) meta-analyses. The effect size of the age at death meta-analyses was large and significant for combined males and females (Spearman's Rho = 0.62; Pearson's r = 0.65), male-only (Spearman's Rho = 0.77; Pearson's r = 0.75), and female-only (Spearman's Rho = 0.71; Pearson's r = 0.71). The overall correlation coefficients of the interrater (Kappa = 0.76; Spearman's Rho = 0.73; Pearson's r = 0.80) and intrarater (Kappa = 0.81; Spearman's Rho = 0.91; Pearson's r = 0.83) reliability meta-analyses were large and significant. A significant degree of heterogeneity was present in all meta-analyses, with minimal evidence of publication bias. The meta-analyses results suggest the S-B method is highly reliable with a moderate-to-high degree of accuracy. Our results also identified sample size and accuracy differences between male and female individuals.

Abstract
Locomotion through the environment is important because movement provides access to key resources, including food, shelter and mates. Central to many locomotion-focused questions is the need to understand internal forces, particularly muscle forces and joint reactions. Musculoskeletal modelling, which typically harnesses the power of inverse dynamics, unites experimental data that are collected on living subjects with virtual models of their morphology. The inputs required for producing good musculoskeletal models include body geometry, muscle parameters, motion variables and ground reaction forces. This methodological approach is critically informed by both biological anthropology, with its focus on variation in human form and function, and mechanical engineering, with a focus on the application of Newtonian mechanics to current problems. Here, we demonstrate the application of a musculoskeletal modelling approach to human walking using the data of a single male subject. Furthermore, we discuss the decisions required to build the model, including how to customize the musculoskeletal model, and suggest cautions that both biological anthropologists and engineers who are interested in this topic should consider.

Abstract
OBJECTIVE To correlate atherosclerosis (Ath) and osteoarthritis (OA) in mummies from ancient Egypt. MATERIALS Whole-body CT examinations of 23 mummies from the Ägyptisches Museum und Papyrussammlung, Berlin, Germany, and 22 mummies from the Museo Egizio, Turin, Italy. METHODS Ath was assessed in five anatomical regions by means of preserved arterial calcifications. OA was assessed using the Kellgren and Lawrence (1957) classification. RESULTS Statistical analysis revealed no correlation between Ath and total OA. A significant association was found for Ath and the upper limb group for OA grade >1 and for Ath and the lower limb group, consisting mainly of the hip and knee, for OA grade >2 OA. CONCLUSIONS The association of Ath and advanced OA of the hip and knee is comparable in prevalence to those reported in recent clinical studies, despite the low life expectancy and the different environment and lifestyle of the ancient Egyptians. SIGNIFICANCE This is the first study to correlate findings of Ath and OA in ancient Egypt statistically. The diseases of Ath and OA are common ailments with enormous and increasing impacts on public health. LIMITATIONS The large number of cardiovascular diseases was indicated only by arterial calcifications that resisted the post-mortem changes of the mummification process. Also, the assessed OA was on radiological OA. SUGGESTIONS FOR FURTHER RESEARCH Genomic studies of ancient Egyptian mummies may reveal genetic risk factors for Ath and OA that could be shared in ancient and modern populations.

INTERNATIONAL JOURNAL OF PALEOPATHOLOGY 2021; 33:280-288.

Abstract
OBJECTIVE A reappraisal of the available evidence of osteopetrosis in the archaeological record as first step in promoting new approaches to rare diseases in paleopathology. MATERIALS AND METHODS Three different approaches are combined: a survey of the last 50 years of bioarchaeological publications; an online search addressing six of the more widely used search engines; macroscopic and radiographic analyses of the human remains from the Neolithic site of Palata 2 (Italy). RESULTS The combined results of the literature survey and the online search identified six cases of osteopetrosis. The majority of search hits place this disease into differential diagnoses. The investigation of the remains from Palata 2, one of the six cases in literature, indicates a non-specific sclerosis of the cranial vault. CONCLUSIONS Of the six cases of osteopetrosis, only two, one of the autosomal-recessive type (ARO) and one of the autosomal-dominant type (ADO), are supported by direct osteoarchaeological evidence. Therefore, inaccurate differential diagnoses generate an inflated number of cases in the paleopathological record. SIGNIFICANCE This reappraisal calls for a more informed and evidence-based approach to osteopetrosis and, more generally, to rare diseases in paleopathology. LIMITATIONS Lack of specific publications on osteopetrosis; more case studies may be present in "gray literature". SUGGESTIONS FOR FURTHER RESEARCH Cases of osteopetrosis from archaeological and historical collections as well as medical literature are needed to increase knowledge about this rare disease. More precise differential diagnoses are required, particularly when dealing with rare diseases.

Abstract
The 'red complex' is an aggregate of three oral bacteria (Tannerella forsythia, Porphyromonas gingivalis and Treponema denticola) responsible for severe clinical manifestation of periodontal disease. Here, we report the first direct evidence of ancient T.forsythia DNA in dentin and dental calculus samples from archaeological skeletal remains that span from the Pre-Hispanic to the Colonial period in Mexico. We recovered twelve partial ancient T. forsythia genomes and observed a distinct phylogenetic placement of samples, suggesting that the strains present in Pre-Hispanic individuals likely arrived with the first human migrations to the Americas and that new strains were introduced with the arrival of European and African populations in the sixteenth century. We also identified instances of the differential presence of genes between periods in the T. forsythia ancient genomes, with certain genes present in Pre-Hispanic individuals and absent in Colonial individuals, and vice versa. This study highlights the potential for studying ancient T. forsythia genomes to unveil past social interactions through analysis of disease transmission. Our results illustrate the long-standing relationship between this oral pathogen and its human host, while also unveiling key evidence to understand its evolutionary history in Pre-Hispanic and Colonial Mexico. This article is part of the theme issue 'Insights into health and disease from ancient biomolecules'.

Abstract
Akin to approaches encouraged by Verano (1997) in the Andes, and Ortner (2011, 2012) for general paleopathological studies, this article focuses on accurate descriptions and definitions of osteoarthritis, entheses, and long bone cross-sectional geometry. By evaluating these conditions as part of biological responses to abnormal skeletal changes and biomechanical stress, this research discusses each condition's pathogenesis. Further, this article emphasizes a "small data" approach to evaluating these conditions in ancient culturally and biologically related human populations, where the study samples must have good skeletal preservation, where estimates of age and sex need to be included as major factors, and where abnormalities need to be described and evaluated. This article also discusses global clinical and osteological research on ways scholars are currently trying to establish industry-wide methods to evaluate osteoarthritis, entheses, and long bone cross-sectional geometry. Recent studies have focused on rigorous evaluation of methodological techniques, recording protocols, and inter- and intra-observer error problems. Additionally, scholars have focused on physical intensity of movement using biomechanics, evaluated burials of known occupation, and used complex statistical methods to help interpret skeletal changes associated with these conditions. This article also narrows to focus on these conditions within thematic "small data" areas throughout the Andes. This research concludes with describing future directions to understand skeletal changes, such as more multidisciplinary studies between osteologists and pathologists, collaborations with living people to collect CT, x-rays, or computer-aided motion capture, and a stronger focus on how these conditions correlate with intense biomechanical changes in younger individuals.
