Agropastoral and dietary practices of the northern Levant facing Late Holocene climate and environmental change: Isotopic analysis of plants, animals and humans from Bronze to Iron Age Tell Tweini.

One of the largest isotopic datasets of the ancient Eastern Mediterranean region is evaluated, based on plants (n = 410), animals (n = 210) and humans (n = 16) from Tell Tweini (Syria). Diachronic analysis of plant and faunal specimens from four main periods of occupation: Early Bronze Age (2600-2000 BC), Middle Bronze Age (2000-1600 BC), Late Bronze Age (1600-1200 BC) and Iron Age (1200-333 BC) were investigated. Mean Δ13C results from seven plant species reveal emmer and free threshing wheat, olives, bitter vetch, rye grass and barley were adequately or well-watered during all periods of occupation.

Endoscopic sinus surgery with medical therapy versus medical therapy for chronic rhinosinusitis with nasal polyps: a multicentre, randomised, controlled trial.

Background: Endoscopic sinus surgery (ESS) is a common operation for patients with chronic rhinosinusitis with nasal polyps (CRSwNP) when medical therapy alone is insufficient. No randomised controlled trials on the efficacy of ESS have been published. We aimed to assess the efficacy of ESS plus medical therapy versus medical therapy alone in patients with CRSwNP.

Influencing factors in the implementation of postgraduate medical e-learning: a thematic analysis.

Background: Postgraduate medical e-learning (PGMeL) is being progressively used and evaluated. Its impact continues to grow, yet there are barriers to its implementation. Although more attention is now being paid to quality evaluation models, little has been written about the successful implementation of PGMeL.

[Healthcare epidemiology of mental disorders : Why is the prevalence not declining despite growing provision of care?].

In Germany, the significant increase of healthcare provision and service use in recent decades has not resulted in a decreasing prevalence of mental disorders.Three explanations for this phenomenon are considered: 1) prevention and the healthcare system are insufficient and ineffective, 2) the success of the healthcare service is masked by growing morbidity due to increasing societal risks, and 3) a fundamental shift towards a psychological culture accounts for an increasing perception and treatment of mental disorders and their symptoms at the same time. In order to review these three theoretical approaches, results from population-based health surveys and healthcare research in Germany as well as the international debate are presented and discussed.
