Notes sur l'ethnicité des tadjiks de Chine

En République populaire de Chine, dans la province du Xinjiang située au Nord-Ouest du pays vivent quelques 33 000 Tadjiks chinois dont 60 à 70 % sont concentrés dans le seul district autonome qui leur ait été accordé en 1954 : celui de Tâshqurghân perché dans les hauteurs des Pamirs. Engloutis par le colonialisme han (ethnie chinoise majoritaire) l'unique échantillon de religion ismaélienne et de langues sarikoli et wakhani disparaissent petit à petit sans que l'on ait éclairé la provenance et les caractéristiques de cette minorité oubliée. Que reste-t-il des Ismaéliens de Chine et qu'est-ce qu'un Tadjik chinois dans les années 1990

Primary Hemostatic Disorders and Late Major Bleeding After Transcatheter Aortic Valve Replacement Auteurs

BACKGROUND: Periprocedural and late (>30 days) bleedings represent major complications after transcatheter aortic valve replacement and have been identified as potential areas for improved patient care. OBJECTIVES: The authors sought to evaluate the impact of ongoing primary hemostasis disorders on late major/life-threatening bleeding complications (MLBCs). METHODS: Bleedings were assessed according to the VARC-2 (Valve Academic Research Consortium-2) criteria. Closure time of adenosine diphosphate (CT-ADP), a surrogate marker of high molecular weight von Willebrand multimers proteolysis was assessed 24 h after the procedure. Ongoing primary hemostasis disorder was defined by a CT-ADP >180 s. RESULTS: Among 372 patients who survived at 30 days, MLBCs occurred in 42 patients (11.3%) at a median follow-up of 383 days (interquartile range: 188 to 574 days). MLBCs were mainly of gastrointestinal origin (42.8%) and were associated with increased overall mortality (hazard ratio [HR]: 5.66; 95% confidence interval [CI]: 3.10 to 10.31; p 180 s (27.4% vs. 11.5%; p 180 s (HR: 3.08; 95% CI: 1.62 to 5.81; p = 0.0005) as predictor of MLBCs. CONCLUSIONS: MLBCs after transcatheter aortic valve replacement are frequent and associated with an increased morbidity and mortality. PVL and CT-ADP >180 s were identified as strong predictors for MLBCs. These findings strongly suggest that persistent HMW defects contribute to enhanced bleeding risk in patients with residual PVL
