U Krogh, A C Storm, P K Theil
The objectives of the present study were to design a method to estimate mammary plasma flow (MPF) in lactating sows using downstream dilution of -aminohippuric acid (AH) and to compare these estimates with MPF estimates based on specific AA as internal markers (MPF-AA). A permanent indwelling catheter was surgically implanted in the femoral artery, and another 2 were inserted in the right cranial mammary vein of 8 second- and third-parity sows on d 76 ± 2 SEM of gestation. On the 3rd and 17th days in milk, arterial and venous blood samples were drawn in hourly intervals from 0...

Semi-permanent dual-lumen tunneled (or tunneled-cuffed) hemodialysis catheters (TDC) are increasingly utilized during renal replacement therapy, while awaiting permanent access maturation or renal recovery. Although there is a wealth of literature focused on placement, infection prevention, and maintenance of catheter patency, circumstances and indications for TDC removal are less well understood. Timely removal of these catheters is an important management decision, with the length of TDC duration representing the largest cumulative risk factor for catheter-associated blood stream infections...

BACKGROUND: The incidence of cardiac morbidity and mortality is high in patients treated with hemodialysis (HD). The aim of this study was to evaluate the relationship between HD and the echocardiographic findings in patients with chronic kidney disease (CKD). METHODS: Between 2012 and 2014, 150 patients with CKD. The echocardiographic data were done based on American Society of Cardiology (ASE). Measurement method for Ejection Fraction was E balling and for Diastolic Function was Tissue Doppler...

It is difficult to treat large internal carotid aneurysms with simple surgical clipping. Here, we present a retrograde suction decompression (RSD) procedure for large internal carotid aneurysms using a balloon guide catheter combined with a blood-returning circuit and a superficial temporal artery to middle cerebral artery (STA-MCA) bypass.All patients underwent an STA-MCA bypass before the temporary occlusion of the internal carotid artery (ICA). A 6-French sheath was inserted into the common carotid artery (CCA), and a 6-French Patrive balloon catheter was placed into the ICA 5 cm past the bifurcation...

PURPOSE: The technique of active urinary endoscopic vacuum therapy (uEVT) is described. The surgical technique is demonstrated in detail with the help of a video of the operation, which is available online. Vesical fistulas are a rare complication following rectal surgery. The EVT technique is a novel method for the treatment of gastrointestinal leakage. This endoscopic procedure has been adapted to treat a large bladder defect after abdomino-perineal resection of the rectum with urine flowing out of the perineal wound...

BACKGROUND: Prognosis and treatment of cystic craniopharyngiomas are poorly defined. OBJECTIVE: To analyze progression-free survival (PFS) and safety profile of cystic craniopharyngiomas undergoing resection or minimally invasive drainage procedures. We compared further outcome measurements for cystic and solid tumors undergoing resection to elucidate the impact of the initial tumor composition on both PFS and the toxicity profile. METHODS: All patients with craniopharyngiomas consecutively treated between 1999 and 2014 were included...

Delivery of a prescribed dialysis dose, which is critical for longevity on hemodialysis, is directly dependent on vascular access (VA). However, VA is fraught with high failure rates and has room for innovation. Arteriovenous fistula (AVF), considered the 'best choice', has a high 'failure to mature' rate. Arteriovenous grafts (AVGs) are considered when patients are poor candidates for or have failed AVF, but have a high incidence of infections and thrombosis. Due to associated morbidity and mortality from complications, central venous catheters are considered only as 'bridging short-term access' when there is an urgent need for dialysis...

BACKGROUND: Conduction disorders requiring permanent pacemaker (PPM) implantation are a known complication of trans-catheter aortic valve implantation (TAVI). Indications for permanent pacing in this setting are still controversial. The study aim was to characterize the natural history of conduction disorders related to TAVI, and to identify predictors for long term pacing dependency. METHODS: Consecutive patients who underwent TAVI were included in this prospective observational study...

BACKGROUND: We report the experience in a cohort of consecutive patients receiving extracorporeal membrane oxygenation during catheter ablation of unstable ventricular tachycardia (VT) at our center. METHODS AND RESULTS: From 2010 to 2015, extracorporeal membrane oxygenation was initiated in 64 patients (average age: 63±15 years; left ventricular ejection fraction in 27±9%; cardiogenic shock in 23%, and electrical storm in 62% of patients) undergoing 74 unstable VT catheter ablation procedures...

Peripherally inserted central catheters (PICCs) have been placed through the peripheral veins, and the best location for the tip of the PICCs is the lower third of the superior vena cava (SVC) and cavo-atrial junction. PICCs are commonly used in intravenous administration, parenteral nutrition therapy, chemotherapy, as well as in critical care units. The success rates in venipuncture are enhanced when ultrasonographic guides are used by the bedside PICC teams. There have been few reports of PICCs placed in super elderly patients with permanent cardiac pacemakers...

Electronic pacemakers have been used in patients with heart rhythm disorders for device-supported pacing. While effective, there are such shortcomings as limited battery life, permanent implantation of catheters, the lack of autonomic neurohumoral responses, and risks of lead dislodging. Here we describe protocols for establishing porcine models of sick sinus syndrome and complete heart block, and the generation of bioartificial pacemaker by delivering a strategically engineered form of hyperpolarization-activated cyclic nucleotide-gated pacemaker channel protein via somatic gene transfer to convert atrial or ventricular muscle cardiomyocytes into nodal-like cells that rhythmically fire action potentials...

Information on effects of supplementing fibrous diets with exogenous enzymes on nutrient absorption and energetic demands of visceral organs is scarce. Therefore, this study investigated the effects of supplementing a high-fiber (HF) diet with a multi-enzyme cocktail (MC) on net glucose and lactate portal fluxes, insulin production, and O consumption by the portal-drained viscera (PDV) and whole animal in growing pigs. The MC supplied (analyzed values) 5,397 U of xylanase, 162 U of β-glucanase, and 2,000 U of protease per kg of diet, and guaranteed minimum activities of 1,000 U of α-amylase and 25 U of pectinase per kg of diet...

INTRODUCTION: Chronic intermittent renal replacement therapy(RRT) is an alternate method of decongestion for patients presenting with diuretic-resistant, end-stage heart failure(HF) and cardiorenal syndrome. The optimal method of vascular access has not been confirmed. This study compared the 6-month outcomes of patients with end-stage HF after the creation of arteriovenous communications (AVC) versus other means of RRT. METHODS: We treated 40 patients with chronic, intermittent, ambulatory RRT, of whom 15 (37...

PURPOSE: Malignant pleural effusion (MPE) is a disabling condition caused in most instances by far-advanced cancer. The treatment is palliative and should ideally be minimally invasive. The aim of this retrospective study was to evaluate the effectiveness of implantation of a permanent PleurX catheter in the treatment of recurrent MPE in patients with terminal cancer disease. PATIENTS AND METHODS: Eighteen consecutive patients with terminal cancer and MPE, who had a permanent PleurX catheter implanted in the period from February 2014 to August 2015, were retrospectively evaluated...

BACKGROUND: An alternative treatment for obstructive and refluxing obstructive megaureter with ureterovesical junction maintenance through laparoscopy is proposed. MATERIAL AND METHODS: The series consists of 8 cases, all of them studied because of prenatal hydronephrosis or febrile urinary tract infection. Seven were diagnosed with obstructive megaureter and one with obstructive refluxing megaureter. The procedure consisted in incising the stenotic portion of the ureter longitudinally and maintaining its posterior wall attached to the bladder, the anterior wall of the ureter was anastomosed transversally to the bladder mucosa in order to liberate the obstruction...
