We present a presumptive case of metastatic carcinoma in an individual from the 11^th/12^th century CE from Vaduz, Principality of Liechtenstein. The skeleton exhibits extensive new bone formation in the axial skeleton and the proximal humerus and femur. Radiological examinations revealed further sclerotic lesions in the clavicles, the manubrium, the sternum, the femoral diaphysis, and possibly the frontal. The pelvic bones and the sacrum, as well as the spine, are the most heavily affected skeletal regions. The newly formed bone in some lesions has a "sun-burst" appearance. The sex and age at death of the individual, the distribution and the osteoblastic nature of the lesions suggest that prostate carcinoma is the most likely primary tumor.

This study analyzed the paleopathological conditions of a 30-year-old male unearthed at the site of Ya'amun in northern Jordan. The skeleton was dated back to Iron age. The paleopathological examinations were performed using macroscopic and radiological analyses. The results revealed multiple significant bone lesions, including periosteal osteosarcoma of the right femur, plagiocephaly, asymmetry of the sacrum, vertebral fractures, anemia, and osteoarthritis. This case represents the first example of neoplasm and plagiocephaly in the Iron Age of the region. Despite enduring severe health conditions, the individual managed to reach the third decade while facing the demands of strenuous daily activities that exemplified the harsh living and subsistence conditions characteristic of the Iron Age.

Objective: This study aims to describe various types of skeletal lesions and lesion patterns observed in five potential cases of treponematosis from the same archaeological site. Material and methods: The study examines five adult skeletons recovered from Santa Maria do Olival, Tomar, Portugal. Macroscopic observations were conducted on all remains, supplemented by relevant radiographic investigations. Results: The analyzed individuals exhibited diverse types of skeletal lesions and distinct patterns of lesion distribution. Radiocarbon dating of two of these skeletons locates them chronologically close to the beginning of the colonial period (15^th century). Discussion: The findings indicate considerable variation in the lesions and lesion patterns associated with treponematosis, even within the same archaeological site. The radiocarbon data implies the presence of pre-Columbian treponemal disease or a rapid progression to the tertiary phase of the disease. This study represents the oldest cases of treponematosis in Portugal and the only one with more than one individual affected from the same archaeological site. Considering Portugal's prominent role in the European Age of Exploration, the study underscores the significance of pathogen exchanges between Europeans, South Americans, Africans, and Asians. Future investigations should reassess Iberian osteological collections from this time period, given the historical importance of Portugal and Spain in the intercontinental movements.

The process of natural or spontaneous mummification has been observed for more than a hundred years in various Mexican pantheons. The construction materials used in the niches of the pantheons generate particular microenvironmental conditions that promote the preservation of organic materials. The construction materials (mining adobe, brick and stone material) that make up the three series of the municipal pantheon of Santa Paula were studied and analyzed using X-ray Diffraction, X-ray Fluorescence and petrographic analysis techniques. At the same time, the mechanical and physical properties of the materials were determined, as well as the relative humidity and temperature within the niches. The results indicate that the geochemistry, distribution and percentage of said materials inside of the niches created exceptional microclimatic conditions that favored the conservation of the bodies. With this contribution we intend to advance the understanding of the influence that construction materials had on the process of natural mummification.

Skeletal remains of an adult (estimated age at death ≈ 27-30 years) Prehispanic male with fusion in the sacroiliac joints showed a heterotopic ossification consisting of a flat, 10 × 5 cm bone formation covering the posterior aspect of the right sacroiliac joint. The bones were recovered from a burial cave containing remains of 4 individuals, located on the side of a ravine, in Buenavista del Norte (NW corner of Tenerife, Canary Islands), at ≈ 450 m altitude. This individual was probably affected by ankylosing spondylitis (AS) that led to bony fusion of the pelvic bones with the sacrum, but several unusual features prompted us to compare the pelvis with those belonging to two modern individuals affected by AS (20^th century) housed at the Department of Anatomy of the school of medicine (University of La Laguna, Tenerife). The Prehispanic individual possibly suffered a pelvic fracture that caused a hematoma which underwent ossification. Some features (periosteal reaction, formation of new foramina) may also suggest a superimposed infection. The fracture altered the pelvic structure, severely narrowing the right sciatic notch, possibly causing neural and/or vascular compromise of the lower limbs. Living in a steep mountainous environment, this individual (possibly a goatherder) probably suffered a fall, that caused the fracture complicated by a severe bleeding and pelvic deformation.

Previous studies have reported that height reduction due to urbanization during the early industrial period was not observed in Japan. This study analyzed the data from 20-year- old conscript examinations from 1905 to 1932 (for individuals born between 1885 and 1912) in Iwate Prefecture, northern Japan. Secular trends in height, weight, body mass index (BMI), prevalence of trachoma, and secondary education attainment classified by Morioka City, the prefectural capital, and 13 counties were examined. Before the 1880s births, the height of those in Morioka was approximately 159 cm, the same height as those in rural areas. After 1880, the height of those in Morioka increased to more than 161 cm in the early 1900s, while the height of those in rural areas remained constant. Large declines in height, > 0.5 cm, were seen in those born in the year or following year of a natural disaster, epidemic, or economic depression. This result may suggest that height increased in urban areas as life improved, experiencing temporary deterioration of their living environment due to recession, natural disasters, and epidemics, whereas height changed little in rural areas because life remained almost the same during the early industrial period in Japan.

During the early development of archaeology in Spain, many of the materials obtained from excavations were later forgotten in museum deposits. However, re-investigation of these collections with contemporary methodologies can still contribute valuable knowledge. This study presents the case of El Bosquet Cave (Mont-ral, Tarragona, Spain), located in the Northeastern Iberian Peninsula. This cave was excavated and documented in 1956 and the recovered materials were transferred, years later, to the Reus Museum, where they are currently located. Our results provide a more precise Middle Bronze Age chronology for the site in addition to bioarchaeological conclusions on the human remains from four individuals. Of note is a healed mandibular fracture in one of the individuals. Trauma observed in human skeletal remains reflect the conditions and risks of human groups in relation to daily activities or may be the result of interpersonal violence. In the Iberian Peninsula there are very few documented cases of mandibular fractures in prehistoric populations. This study contributes to the knowledge of the populations of the recent prehistory in the region of Catalonia and highlights the importance of reanalyzing the collections that are deposited and, in many cases forgotten, in the different museums of the territory.

Introduction: The growth hormone/insulin-like growth factor-1 axis (GH/IGF-1) is crucial for longitudinal bone growth and exerts several metabolic effects. It is debatable whether and how the recombinant human growth hormone (rhGH) treatment affects the trunk-limb proportions. Aim of the study: We aim to evaluate the changes in body proportions and body fat content in short children with growth hormone deficiency (GHD), children born small for gestational age (SGA), and girls with Turner syndrome (TS) during the first year of rhGH therapy. Material and methods: The data of 70 children with GHD, 40 children born SGA, and 36 girls with TS from 1998 to 2019 were analyzed. The following parameters were measured: height, body weight, sitting height, and two skinfolds on the arm above the triceps brachii and below the scapula at the beginning of rhGH therapy and after the first year of treatment. Sitting height and lower limb length were presented as percentages (%) of body height. Fat mass percentage (%FAT) was calculated using the Slaughter formula. Results: At the beginning of rhGH, TS girls had the greatest height deficit (-2.7 SDS), the highest sitting height (%), and the lowest lower limb length (%) compared to children with GHD and children born SGA. Moreover, TS girls had higher body weight SDS, BMI SDS compared to SGA children (p < 0.001), and higher %FAT compared to both GHD and SGA children (p < 0.001 for both). After the first year of rhGH therapy, a significant increase in lower limb share (%) and a decrease in %FAT were observed in all the study groups. TS girls still had significantly higher sitting height (%), shorter lower limbs (%), and higher %FAT, body weight SDS, and BMI SDS compared to children with GHD and children born SGA (p < 0.05 for all variables). Conclusions: Our results show that rhGH treatment could increase lower limb length in relation to height and reduce fat mass in treated children. Girls with TS had the largest baseline body disproportions and the highest body fat content. Despite a satisfactory reduction in height deficit, after the first year of rhGH therapy, these girls had still higher body weight SDS, BMI SDS, %FAT, the highest sitting height (%), and the lowest lower limb length (%) compared to children with GHD and born SGA.

In March 2020, the spread of the new coronavirus SARS-CoV-2, triggered a pandemic of acute respiratory distress syndrome among people. The aim of the study was to evaluate the changes in BMI and in the prevalence of overweight and obesity in children and adolescents (11-15-year-olds) from Kraków (Poland) during the COVID-19 pandemic. Two cross-sectional studies were performed in 2020 and 2022 in randomly selected elementary schools in 4 districts of Kraków. The study group was 1572 children between the ages of 11-15 years. BMI (Body Mass Index) was calculated. Participants were grouped using Cole's cut-off points. The statistical significance of differences between the groups was estimated using the two-way ANOVA and Chi² test. An increase in the prevalence of underweight and normal weight was observed in both sexes. In girls a decrease in the prevalence of obesity was noted, while in boys, the same tendency was present in some age groups. In girls, a decrease in the prevalence of overweight and in the average BMI was noted; in boys the trend was the opposite. The observed results may be correlated with changes in body composition and restrictions resulting from the lockdown caused by the COVID-19 pandemic.

The aim of the present study was to advance knowledge of the secular changes in the prevalence of excess weight (overweight and obesity) and body composition of children living in different localities of La Plata district (Buenos Aires province, Argentina) over the last two decades. For this purpose, anthropometric data and information on the socioeconomic and environmental context of residence of schoolchildren aged 4.0-12.9 years collected during 2005-2009 (Cohort 1, n = 1 233) and 2016-2019 (Cohort 2, n = 1 499) were analysed and compared. From a secular perspective, the current analysis showed that the socioeconomic and environmental conditions of families living in La Plata district have deteriorated in recent decades. In this context, child excess weight increased by 13% and body composition was altered, mainly as a result of an increase in fat mass, without observing changes in the muscle component.
