The aim of this paper is to analyze the morphology of a skull from Candonga Cave (central Argentina), dating to the Pleistocene-Holocene transition, and to discuss its implications for the early peopling of South-America by Palaeoamerican and Amerindian populations. Although this cranium is fragmented, impeding the standard morphometric analysis, an alternative methodology ad hoc was implemented in order to obtain relevant information about the South American people origins. Results of measurements provide new information to reinforce the hypothesis that Paleoamerican crania possess similar morphological traits to those of current Fueguian populations, as previous studies have claimed, and to suggest that the cranium of Candonga has strong morphological affinities with Early Holocene specimens from Lagoa Santa (Brazil) and Late Holocene of Beagle Channel (Argentina), both belonging to Paleoamerican morphology.

Long bone shaft fragments can be found isolated in archaeological and forensic contexts, such as in mass fatality incidents. When diagnostic morphological landmarks are not visible, the assessment of a human or non-human origin of a bone fragment can be challenging. Further methods need to be developed. In long bones, the presence of a nutrient foramen on fragments that do not show any diagnostic landmarks can make the assessment of the origin of the bone still possible. In this paper, human long bones were compared to those of the following species: chicken (Gallus gallus domesticus), duck (Cairina moschata), sheep (Ovis aries), pig (Sus scrofa domesticus), and deer (fallow deer, Dama dama, and roe deer, Capreolus capreolus). Macroscopic evaluation of location, direction and appearance, and micro-CT scanning in order to measure angle and shape of canal entrance, were applied in this study to differentiate human from non-human nutrient foramina on long bone shafts. Observations regarding the location and direction of nutrient foramina were proven to be different between human and non-human bones; however, these two features might not be exploitable in cases of highly fragmented bones. The foramina appearance was the most reliable for the origin identification, although the shape of the canal entrance and its angle at the cortical bone, obtained from micro-CT scans, were also useful parameters. For a correct identification of a fragment, one parameter may not be enough and it is advisable to employ as many features as possible. This research demonstrates that nutrient foramina have potential as a reliable bone feature for the distinction between human and non-human fragmented and incomplete long bones.

It has been shown that women who have undergone mastectomy (BG) demonstrated greater postural changes than women after breast reconstruction. In this study we wanted to verify if unilateral mastectomy affected body weight distribution and balance in a standing position and if the weight of an external breast prosthesis (EBP) influenced those variables and might provide some insight into the current post-mastectomy care. In our study BG completed the data acquisition protocol in 4 variants: 3 trials without EBP (group A), and the next 9 trials with 3 different weights of EBP. Group B - wearing a prosthesis weighing 10 grams; Group C - wearing a prosthesis weighing 50% of the total breast mass; Group D - wearing a prosthesis of equal weight to the operated breast. Each control group subject (CG) completed 3 consecutive trials. Instrumental assessment of body balance was conducted using FDM pressure distribution measurement platforms. This is a quantitative baropedometric tool which allowed for measuring forces exerted on the support surface in a standing position. Ellipse width, length, area and the center of feet pressure (CoP) path did not differ significantly between the measurements performed in different groups. Group D was closest to CG in terms of the width and length of the ellipse. Group C, on the other hand, was most similar to CG with respect to the other study variables. The study results suggest that women after mastectomy do not differ from the healthy subjects neither with regard to CoP features nor in terms of weight distribution on the supporting surface.

This work aimed to study the variability in location of the asterion in a Polish population, which may be important for both surgical and anthropological procedures. In surgical approaches to the posterior cranial fossa, the asterion is of great importance as a reference landmark. Its accurate localization may be impeded by the presence of additional, irregular sutural bones. Dry adult human skulls (n = 113, 60.2% male and 39.8% female) were analyzed for asterion location in relation to the reference points (mastoidale, bregma, porion, inion, lambda, opisthion). The asterion exhibits wide variation in location. The range of ± 2 SD of measured distances demonstrated broad variation intra and interindividually (15.9-27.8 mm for male skulls and 13.1-24.6 mm for female skulls). Distances from the asterion to the reference landmarks were longer for males compared to females (p < 0.05), and some distances were longer for people of lower socioeconomic status. Because of its lesser variation, measurements to three reference landmarks (mastoidale, bregma and frontotemporale) may be particularly important for surgical purposes. Defining accurately the safe area for asterion is important but problematic. Because of the complex relations between bony landmarks, preoperative imaging assistance is required, and the asterion should only be used as auxiliary, not as a key superficial cranial landmark in surgical interventions.

One of the issues within the framework of Darwinian medicine is why individuals develop the specific disease they do. Ethologists have long known that within any given population, there are organisms with the tendency towards higher (Hawks) or lower (Doves) aggressiveness, and since the physiological responses to stressful events are different in Hawks and Doves, it has been suggested that these strategies might be related to health outcomes. The aims of this exploratory study were to determine whether an analogues of Hawks and Doves as basic coping strategies could be defined among chronically ill patients and healthy controls and whether the proportion of Hawks and Doves differs among different groups of patients. Patients from several clinical departments (dermatology, gastroenterology and psychiatry) and a comparable group of healthy participants were recruited (N = 288). Based on their coping style and anxiety trait, they were categorized as either Hawks (low anxiety trait and problem-oriented coping style) or Doves (high anxiety trait and avoidant coping style). We found a significantly larger proportion of Hawks among patients with gastroenterological and dermatologic symptoms, and significantly more Doves among psychiatric patients. The proportion of Hawks and Doves in healthy controls was close to 50:50. This is in accordance with the notion that Hawks and Doves have different allostatic load management, and that the onset of certain diseases might be related to these strategies. However, prospective longitudinal studies are necessary to reach definite conclusions regarding the susceptibility to certain diseases among people with different stress-related behavioral and emotional strategies.

An excavation of a burial mound at Norabak site (Southeast Armenia) unearthed four burial chambers, the central one contained a single skeleton radiocarbon dated to about 1400-1200 BCE. The skeleton was observed to have a polyarticular erosive arthropathy, primarily affecting the spine, with diagnostic features of ankylosing spondylitis. The antiquity of ankylosing spondylitis is questioned in the literature, because there are few reliable and descriptive reports from prehistoric sites. Excellent preservation of the skeleton from Norabak made it possible to perform a detailed analysis of the pathologic changes and to support the diagnosis of ankylosing spondylitis in this 3000-years-old individual. Apart from the main pathology, the skeleton had a dens axis fracture of the C2 vertebra a few days before death, as well as a likely associated fracture of the C1 vertebra. This type of fracture has a high risk of displacement into the vertebral canal with severe neurological consequences. Thus, we were presented with an opportunity to reconstruct a possibly fatal event in the life of this individual. The described case provides further evidence that ankylosing spondylitis is a disease of fairly great antiquity.

Although the practice of autopsy on the Pope's corpse was performed from the 16th century, autopsy reports are only rarely analysed, and never with the aim of investigating the real causes of the death from a concomitant medical and historical point of view. Here, for the first time, we report on the discovery of new unpublished documents from the Vatican Secret Archives and their investigation by a scientific and inter-disciplinary approach. This analysis allows us to draw new conclusions on the true cause of Leo XII's mysterious death. His sudden death, that occurred on February 10th, 1829 after a short illness, particularly struck the public. Suspicions of poisoning or surgeon's guilt or inexperience and even the shadow of a venereal disease, contributed to create a "black legend" on his pontificate and death. On the contrary, the present paleopathographic analysis points toward a new conclusion. The regular use of catheterization with a silver syringe provided an easy access for bacterial superinfection, confirmed by the observed early emphysematous stage of the corpse. So, the most substantiated hypothesis concerning the cause of Leo XII's death indicates a severe form of sepsis, exacerbated by a weakened state due to chronic hemorrhoids.

The aim was to analyze the changes in mandibular dental arch shape during adolescence and assess its relation to late mandibular incisor crowding. Longitudinal study included 68 orthodontically untreated subjects (49% female) and analyzed their data for the ages of 12, 15, 18 and 21 years. Measurements included anterior arch depth, intercanine, interpremolar/anterior and intermolar/posterior width, Little's Irregularity and Bolton's index and the ratio between anterior arch depth and width. Males had significantly greater posterior widths than females at any age (p < 0.05). The anterior arch depth continuously decreased (p < 0.05), while width increased after the age of 18 years. Mandibular incisor crowding increased during all investigated periods (p < 0.05). The increase of intercanine width at 12-21 years of age reduced the risk for mandibular incisor crowding in the same period by 74% (OR: 0.265: 95% CI 0.076-0.931; p = 0.045). The shape of mandibular dental arch continues to change during adolescence becoming more squared while mandibular incisor crowding increases. The increase in mandibular intercanine width reduces the risk of crowding.

Ancient Egyptians experienced a vast increase in population size following the Neolithic Revolution. Nomadic hunter-gatherer groups gradually adopted agriculture as their primary food subsistence strategy. Analyses of human societies shifting from foragers to farmers have provided evidence which suggests this transition is linked with an increase in disease and allostatic load. This paper presents an examination of cribra orbitalia and porotic hyperostosis prevalence in Predynastic and Dynastic Egyptians using public health evidence as a means to interpret the skeletal findings. The sample included 219 individuals from the regions of Naga-ed-Dêr, Mesheikh, Giza, and potentially El-Ahaiwah. The aim of this study was to identify significant differences of cribra orbitalia and porotic hyperostosis across time and sex. Application of a Fisher-Freeman-Halton's test indicated there were no differences in prevalence of cribra orbitalia or porotic hyperostosis between the Predynastic and Dynastic, nor were there differences between the sexes. The results of this study did not produce any evidence for an epidemiological shift to have occurred in post-agricultural Egypt. Further, the most likely explanation of the pattern of disease stems from a parasitic model of infection.

The use of genetic information for anthropological purposes requires an effort by the researcher to deal with the ethical issues that may arise. In some cases, these can lead to rather complex relationships between anthropologists and communities. The transparency of the research protocol is a fundamental requirement in order to establish a relationship based on trust and to conduct investigations in the most ethically sustainable way. In addition, researchers must take into consideration further aspects regarding the indigenous conceptions of corporeity, memory and history. Knowledge of these characteristics can help in the interpretation of results produced by the geneticists, and constitute a series of social, political and cultural responses. By involving the communities being investigated and engaging in a frequent and fruitful dialogue with their members will make it possible for anthropologists to learn more and also provide useful answers for the populations themselves.

Capocasa, Laura Volpi","doi":"10.1127/homo/2019/1095","DOIUrl":"https://doi.org/10.1127/homo/2019/1095","url":null,"abstract":"The use of genetic information for anthropological purposes requires an effort by the researcher to deal with the ethical issues that may arise. In some cases, these can lead to rather complex relationships between anthropologists and communities. The transparency of the research protocol is a fundamental requirement in order to establish a relationship based on trust and to conduct investigations in the most ethically sustainable way. In addition, researchers must take into consideration further aspects regarding the indigenous conceptions of corporeity, memory and history. Knowledge of these characteristics can help in the interpretation of results produced by the geneticists, and constitute a series of social, political and cultural responses. By involving the communities being investigated and engaging in a frequent and fruitful dialogue with their members will make it possible for anthropologists to learn more and also provide useful answers for the populations themselves.","PeriodicalId":46714,"journal":{"name":"Homo-Journal of Comparative Human Biology","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2019-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79763771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
