    Abstract Background Non-tunneled (temporary) hemodialysis catheters (NTHCs) are the least-optimal initial vascular access for incident maintenance hemodialysis patients yet little is known about factors associated with NTHC use in this context. We sought to determine factors associated with NTHC use and examine regional and facility-level variation in NTHC use for incident maintenance hemodialysis patients. Methods We analyzed registry data collected between January 2001 and December 2010 from 61 dialysis facilities within 12 geographic regions in Canada. Multi-level models and intra-class correlation coefficients were used to evaluate variation in NTHC use as initial hemodialysis access across facilities and geographic regions. Facility and patient characteristics associated with the lowest and highest quartiles of NTHC use were compared. Results During the study period, 21,052 patients initiated maintenance hemodialysis using a central venous catheter (CVC). This included 10,183 patients (48.3 %) in whom the initial CVC was a NTHC, as opposed to a tunneled CVC. Crude variation in NTHC use across facilities ranged from 3.7 to 99.4 % and across geographic regions from 32.4 to 85.1 %. In an adjusted multi-level logistic regression model, the proportion of total variation in NTHC use explained by facility-level and regional variation was 40.0 % and 34.1 %, respectively. Similar results were observed for the subgroup of patients who received greater than 12 months of pre-dialysis nephrology care. Patient-level factors associated with increased NTHC use were male gender, history of angina, pulmonary edema, COPD, hypertension, increasing distance from dialysis facility, higher serum phosphate, lower serum albumin and later calendar year. Conclusions There is wide variation in NTHC use as initial vascular access for incident maintenance hemodialysis patients across facilities and geographic regions in Canada. Identifying modifiable factors that explain this variation could facilitate a reduction of NTHC use in favor of more optimal initial vascular access

    Risultati preliminari delle indagini archeologiche ed etnografiche presso il sito di Togolok 1

    Modern Turkmenistan is mainly constituted by a desert landscape, yet despite its harsh climate, cultures have been able to construct networks of water channels since the Bronze Age. This has resulted in a man-made landscape that integrates towns and villages. Extensive surveys and recent archaeological excavations have highlighted that between 2400 and 2100 BC (Namazga V period), the region of the Murghab alluvial fan was characterised by the development of complex urban societies. However, starting from the Late Bronze Age, a new group of mobile pastoralists appeared in the Murghab region and settled along the edges of the sedentary sites. Although their presence is well-attested both by survey and excavation data, their degree of interaction with the sedentary farmers is still debated. In modern Turkmenistan, semi-mobile shepherds continue to drive their cattle across the Murghab, using mobile camps for different months. This paper presents the preliminary results of the excavation of the sedentary site of Togolok 1, as well as the first ethnographic study of the mobile communities of the Murghab region
