The Upper Arba de Biel constitutes a small valley in north-eastern Spain where a detailed study of five archaeological sites (Peña-14, Legunova/Rambla, Valcervera and Paco-Pons) has been performed, defining the recurrent prehistoric occupation from the Late Magdalenian until the Chalcolithic.
A new series of 20 radiocarbon dates refined the chronology of recurrent human occupations at this site during the late Pleistocene (13,260 cal BP), the Pleistocene-Holocene transition (12,920 11,750 cal BP), the early Holocene (11,300 9300 cal BP), and the late Holocene (1180 cal BP), demonstrating the strategic importance of this site during the prehistory of the region.
"This crisis stems from the prolonged occupation and recurrent hostilities, alongside a system of policies that undermine the ability of Palestinians to live normal, selfsustaining lives and realize the full spectrum of their rights, including the right to self-determination".
9 10 Extrinsic risk factors of recurrent shoulder instability include occupations which involve using the upper limb above chest height, 8 collision sport 11 or playing surface.
Other factors such as a bony Bankart lesion, nerve palsy and occupation influenced rates of recurrent instability.
Occupation was a factor in recurrent instability as Sachs et al 8 reported that those who worked with their arms above chest height were more likely to suffer from recurrent instability (p=0.006, OR=5.762).
Chi-square test was also used to compare the prevalence of recurrent aphthous ulceration between categories of age, gender, education, occupation and family history of recurrent aphthous ulceration.
Other factors such as a bony Bankart lesion, nerve palsy and occupation were shown to influence rates of recurrent instability.
In women, the effect of occupation was not reduced by controlling for self-reported occupational noise exposure or by controlling for leisure-related noise, recurrent ear infections, head injuries and smoking.
Although bony Bankart lesions, Hill Sachs lesions, occupation, physiotherapy treatment and nerve palsy were risk factors for recurrent instability, the evidence was weak using the GRADE criteria these findings relied on poorer quality studies or were inconsistent among studies.
