Permanent dual lumen catheters (PDLC) provide alternative vascular access in patients considered unsuitable for arteriovenous fistula, arteriovenous graft or peritoneal dialysis. Experience with their use for long-term haemodialysis is presented. Between January 1990 and April 1994, 101 catheters were inserted into 63 patients (median age 62 years). A PDLC was the primary vascular access type in 5 patients. Of the first catheters, 70% were inserted percutaneously into the subclavian vein. The median duration of catheter use was 168 days (range 5-1582 days). The overall cumulative observed catheter survival rate was 94% at 6 months, 89% at 1 year and 75% at 4 years following insertion. The major complications were blockage and catheter related infection occurring in 28% and 15% of catheters, respectively. Death and blockage were the commonest reasons for catheter removal. PDLC play a vital role in the provision of access for long-term dialysis and should be considered the access type of choice in patients with limited life expectancy.

Precise genetic parameter estimates can allow the breeding value evaluation to be adjusted to meet European requirements and to enable participation in the international evaluation of Simmental bulls conducted by Interbull. Genetic parameters were estimated for a multitrait multilactation random regression test-day model for milk in Simmental cattle in Poland. Data came from the official Polish national recording system.

Compositions of ethylene glycol dicyclopentenyl ether methacrylate (EGDEMA), a vegetable oil based alkyl methacrylate (C13MA), and furfuryl methacrylate (FMA) were terpolymerized for dual-crosslinked networks with tailored mechanical and thermal properties. Specifically, initiators for continuous activator regeneration (ICAR) atom transfer radical polymerization (ATRP) afforded materials with tailored glass transition temperature ( ) and incorporation of furan and norbornene functionalities within a single chain. The terpolymer with high furan and norbornene functionality (Ter2: = 0.

Background: Advances in secondary stroke prevention, including direct oral anticoagulants (DOACs), dual antiplatelet therapies (DAPT), and cardiovascular risk management, have changed costs over the past decade. This study aimed to evaluate annual treatment costs and trends in drug-based secondary prophylaxis after ischemic strokes.
Methods: Annual treatment costs were evaluated using the net costs per defined daily dosage (DDD) of discharge medications for ischemic stroke patients treated in 2020 at the University Hospital Frankfurt, Germany.

Article Synopsis
- Thousands of young adults experience traumatic brachial plexus injuries (TBPIs), which often result in permanent disabilities and difficulties returning to work, creating social and economic challenges.
- The study aims to assess return-to-work rates after TBPI and compare outcomes between healthcare systems in Germany, Serbia, and the UK.
- Preliminary findings suggest that about 60% of TBPI patients manage to return to work, but often in different occupational roles, indicating ongoing challenges in patient reintegration despite variations in healthcare support.
Cardiac pacing: indications, modalities, complications, and challenges (results of a multicenter cross-sectional study in four hospitals in Dakar, Senegal).

Introduction: cardiac pacing is the only lifesaving procedure which is effective for major cardiac conduction disorders. In sub-Saharan Africa, few pacemakers are implanted, compared to Western countries. This study aimed to describe the indications for cardiac pacing in four hospitals in Senegal, to evaluate its practical modalities, to identify pacemaker's complications and their predisposing factors and to evaluate the main challenges for cardiac pacing in Senegal.
