During prenatal development, the brain is considered the best maturation criterion for the estimation of foetal physiological age, regardless of the conditions of pregnancy. Unfortunately, the brain lyses very quickly after death, but fortunately, the brain also has a major influence over osseous structures of the cranial base during development. Therefore, we considered the osseous structures of the cranial base potential indirect maturation indicators of foetal age. Because of its early formation and robustness, the basioccipital is a cranial base bone that is often used for studies in biological anthropology. Studies generally use conventional morphometry and bone size ratio to highlight morphological changes occurring during the foetal period and to create age estimation methods. These methods usually define thresholds beyond which the morphology of the basioccipital changes, but do not fully consider the form that might be valuable precisely to visualize its development or improve age estimation methods. Using geometric morphometric methods, the present study aims to analyse the development of the basioccipital during the second and third trimesters of foetal life by quantifying and visualizing shape changes in the inferior view. Basioccipital shapes are used as direct indicators of the maturation of the cranial base and as indirect indicators of the maturation of the brain and, by extension, the whole body. A sample of 221 anonymized computed tomographic (CT) scans of normal foetuses, ranging from 18 to 41 gestational weeks (GW), was used. Elliptic Fourier analysis (EFA) was used to quantify the basioccipital outline, and maturation stages were established to visualize shape changes with a principal component analysis. Our study allowed us precisely to quantify and continuously visualize shape changes occurring during prenatal life. Additionally, this study provides the first evidence of two distinct linear shape trajectories of the basioccipital. Foetuses aged between 18 and 26 GW have a rapid shape change with well‐individualized stages, whereas shape changes are less visible in the second trajectory (27–41 GW). Furthermore, intra‐stage shape variation is higher for the basioccipital at the beginning of the second and third trimesters than at the first trimester. By using geometric morphometric methods and EFA, this study shows that it was possible to go beyond classical methods. Indeed, the developed methodology enabled the first quantification of the overall shape changes of the basioccipital between gestational ages. The morphological shape changes throughout the foetal period can be useful for anthropological studies and provide new perspectives for immature age estimation methods. [ABSTRACT FROM AUTHOR]

Abstract: This study covers a fifty-year period between 1953 and 2005 and looks at secular trends in stature, weight and sitting height sizes among French boys and girls between the ages of 3 and 11. A special modelling in function to the age and variable for each child was established so that a comparison could be made in the kinetic growth patterns over these same two periods. Statistical analysis shows a significant increase in growth, of 0.8cm per decade in stature, characterised by a certain increase in the lower limbs and the weight (0.8kg per decade) together with a proportional increase on the body mass index. Positive secular trends of this anthropometric nature are generally thanks to improved eating and sanitary habits and this study enables us to build and elaborate new standards in growth patterns essential for monitoring auxological development in 3 to 11-year-old children in the years 2000 and onwards.

Two probabilist methods of age prediction in children are proposed: they are both based on the radiological presence of erupted teeth or germs. Using an apprenticeship sample of known age and sex, we established several discriminant models (±13,±16,±18 years old). We also evaluated a Bayesian model with the following age groups: <13, [13–16[, [16–18[, &ges;18 years old, or [X and Y] years old. When applied on a known test sample, Fisher''s linear functions presented a success rate greater than 90%, above 13 years threshold, and below 16 and 18 years thresholds, and Bayesian approach, greater than 85%. Therefore, these methods provide an interesting alternative for children age determination that can be applied in biological and forensic anthropology, too. To cite this article: B.

A mass grave was discovered in late autumn 2001 in Vilnius, during constructions works. Preliminary observations led to the conclusion that this mass grave contained part of the Great Army of Napoleon I, and had been created during the Retreat from Russia (December, 1812). In March 2002, an extensive excavation was carried out on a first part of the mass grave, in the framework of a Franco-Lithuanian collaboration, completed by a second excavation of another trench in September 2002. The laboratory study of all the skeletal material ended in October 2002. These preliminary results bring new additional data to the historical knowledge of this major event in the European history; this exceptional sample represents the biggest historical mass grave discovered until now.

People aged 75 and over, frail or dependent are the most frequently hospitalized, particularly via the emergency department, and are sometimes readmitted to hospital less than a month after their discharge. Article 70 of the 2012 social security financing act has set up experiments aimed at improving the care pathway for the elderly. In this context, Marseille University Hospital has developed a table of help and grid for identifying the risk of aggravation of the elderly (Tagravpa). Comprising nine medical-psycho-social items, the grid enables the identification of the risk of aggravation to which is associated a score for identifying the risk of early re-hospitalization for the modeling of care pathways. A study was conducted in two departments. In cardiology for readmission at 1 month the results showed a grid positivity threshold of 6 for sensitivity measured at 56,6% (95% CI: 22,7-84,7) and specificity of 61,5% (95% CI: 40,7-79,1). In Emergency Department the results showed a positivity threshold of 4 for sensitivity at 83,3% (95% CI: 57,7-95,6) and specificity at 45,5% (95% CI: 36,8-54,3). This grid, called TAGRAVPA appears as a simple tool for identifying the risk of early re-hospitalization. It is applicable in a hospital environment, whatever the department and allows the initiation of an adapted path for the elderly person hospitalized or returning home from the emergency department.

Objective. To examine measurement of body composition by ultrasound compared with a reference technique:dual energy X-ray absorptiometry (DXA). We evaluated the accuracy of a portable ultrasound-based device in estimating total body fat mass with those assessed by DXA in adult. Methods. Body fat mass has been estimated using a portable ultrasound-based device in comparison with a contemporary reference DXA apparatus: the Hologic Discovery A. Anthropometric data has been assessed in order to maximize the output of the software associated with the ultrasound-based device. A cross-validation between ultrasound technique (US) and DXA was developed in this study. Total body fat mass estimated by ultrasound was compared with this DXA model in a sample of 83 women and 41 men. Results. Ultrasound technique (US) of body fat (BF) was better correlated with DXA in both women (r (2) = 0.97, P < 0.01) and men (r (2) = 0.92, P < 0.01) with standard errors of estimates (SEE) being 2.1 kg and 2.2 kg, respectively. Conclusion. The use of a portable device based on a US produced a very accurate BF estimate in relation to DXA reference technique. As DXA absorptiometry techniques are not interchangeable, the use of our ultrasound-based device needs to be recalibrated on a more contemporary DXA.
