The aim of this paper is to analyse what is the impact of the second phase of the creation of the Common European Asylum System (CEAS) in the protection of rights of Asylum Seekers in the European Union. The establishment of a CEAS has been always a part of the development of the Area of Freedom, Security and Justice. Its implementation was planned in two phases: the first one, focused on the harmonisation of internal legislation on minimum common standards; the second, based on the result of an evaluation of the effectiveness of the agreed legal instruments, should improve the effectiveness of the protection granted. The five instruments adopted between 2002 and 2005, three Directives, on Qualification, Reception Conditions and Asylum Procedures, and two Regulations, the so-called “Dublin System”, were subjected to an extensive evaluation and modification, which led to the end of the recasting in 2013. The paper discusses briefly the international obligations concerning the rights of asylum seekers and continues with the presentation of the legal basis of the CEAS and its development, together with the role of the Charter of Fundamental Rights of the European Union in asylum matters. The research will then focus on the development in the protection of asylum seekers after the recasting of the legislative instruments mentioned above. The paper will note that the European standards result now improved, especially concerning the treatment of vulnerable people, the quality of the application procedure, the effectiveness of the appeal, the treatment of gender issues in decision concerning procedures and reception. However, it will be also highlighted that Member States maintained a wide margin of appreciation in many fields, which can lead to the compression of important guarantees. This margin concerns, for example, the access to free legal assistance, the definition of the material support to be granted to each applicant for international protection, the access to labour market, the application of the presumptions of the “safety” of a third country. The paper will therefore stress that the long negotiations that characterised the second phase of the CEAS undoubtedly led to some progress in the protection of Asylum Seekers in the EU. However, some provisions are still in open contrast with the international obligations concerning rights of asylum seekers, while others require to the Member State consider carefully its obligation in the choice of internal policies concerning asylum matters.

Biomechanical adaptations that occur during pregnancy can lead to changes on gait pattern. Nevertheless, these adaptations of gait are still not fully understood. The purpose was to determine the effect of pregnancy on the biomechanical pattern of walking, regarding the kinetic parameters. A three-dimensional analysis was performed in eleven participants. The kinetic parameters in the joints of the lower limb during gait were compared at the end of the first, second, and third trimesters of pregnancy and in the postpartum period, in healthy pregnant women. The main results showed a reduction in the normalized vertical reaction forces, throughout pregnancy, particularly the third peak. Pregnant women showed, during most of the stance phase, medial reaction forces as a motor response to promote the body stability. Bilateral changes were observed in hip joint, with a decrease in the participation of the hip extensors and in the eccentric contraction of hip flexors. In ankle joint a decrease in the participation of ankle plantar flexors was found. In conclusion, the overall results point to biomechanical adjustments that showed a decrease of the mechanical load of women throughout pregnancy, with exception for few unilateral changes of hip joint moments.

PURPOSE: Malignant ascites is debilitating for patients with advanced cancer. As shown previously, tumour cell production of vascular endothelial growth factor might be a major cause of the formation of malignant ascites. Intraperitoneal bevacizumab could therefore be an option for symptom control in refractory ascites. PATIENTS AND METHODS: Patients with advanced gastrointestinal cancer and malignant ascites who had undergone paracentesis at least twice within the past 4 weeks were randomly assigned in a 2:1 ratio to intraperitoneal bevacizumab (400 mg absolute) or placebo after paracentesis. During the 8-week treatment period, a minimum interval of 14 d was kept between the applications of the study drug. Primary end-point was paracentesis-free survival (ParFS). RESULTS: Fifty-three patients (median age 63 years) were randomised. Forty-nine patients received at least one study drug application and qualified for the main analysis. The proportion of patients with at least one common toxicity criteria grade III-V event was similar with 20/33 (61%) on bevacizumab and 11/16 (69%) on placebo. Median ParFS was 14 d (95% confidence interval [CI]: 11-17) in the bevacizumab arm and 10.5 d (95% CI: 7-21) on placebo (hazard ratio 0.74, 95% CI: 0.40-1.37; P = 0.16). The longest paracentesis-free period was 19 d on bevacizumab (range 6-66 d) and 17.5 d in the placebo arm (range 4-42) (P = 0.85). Median overall survival was 64 d (95% CI: 45-103) on bevacizumab compared to 31.5 d (95% CI: 20-117) on placebo (P = 0.31). CONCLUSION: Intraperitoneal bevacizumab was well tolerated. Overall, treatment did not result in a significantly better symptom control of malignant ascites. However, patients defined by specific immune characteristics may benefit.
