62%, p = 0.004) but not late (100% vs. 97%; p = 0.15). There was no difference in modifiable cardiopulmonary bypass factors (mean arterial pressure, minimum oxygen delivery (DO2i), retrograde autologous prime, circuit prime volume) between the two groups; however, prime volume decreased and DO2i increased over time for both. Patients refusing transfusion had lower postoperative blood loss (p = 0.02) and shorter postoperative length of stay (p  less then  0.001) with no difference in morbidity (p = 0.46) or mortality (p = 0.68). CONCLUSION Refusal of transfusion in patients undergoing cardiopulmonary bypass was associated with reduced acute kidney injury, hospital stay and postoperative blood loss, while not impacting mortality.Background. Controlled whole-body vibration (CWBV) training has been applied to people with stroke. However, it remains inconclusive if CWBV reduces fall risk in this population. Objective. To (1) assess the immediate and retention effects of CWBV training on fall risk factors in people at postacute and chronic stages of stroke and (2) examine if CWBV dosage is correlated with the effect size (ES) for 3 fall risk factors body balance, functional mobility, and knee strength. Methods. Twelve randomized controlled trials were included. ES was calculated as the standardized mean difference, and meta-analyses were completed using a random-effects model. Results. CWBV training may lead to improved balance and mobility immediately after training (ES = 0.27, P = .03 for balance; ES = 0.34, P = .02 for mobility) but not at the 3-month follow-up test (ES = 0.02, P = .89 for balance; ES = 0.70, P = .11 for mobility). CWBV affects knee strength capacity with mild ES (ES = 0.08 and 0.11, respectively, for immediate and retention effect; P ≥ .68 for both). Metaregression indicated that the immediate ES is strongly correlated with training dosage for balance (r = 0.649; P = .029) and mobility (r = 0.785; P = .036). Conclusions. CWBV training may benefit balance and mobility immediately, but the training effect may not persist among people with stroke. Additionally, the CWBV dosage correlates with the ES for body balance and mobility. More high-quality studies are needed to determine the retention effects of CWBV training.INTRODUCTION Midline catheters are widely used in clinical practice. Proper placement of midline catheter tip is usually assessed only by aspirating blood and flushing with normal saline without resistance. PURPOSE To describe the ultrasound-guided tip location for midline catheters and its feasibility and to compare incidence of catheter-related venous thrombosis associated with or without ultrasound tip localization. METHODS The ultrasound-guided tip location is described step by step. Feasibility of the technique and incidence of catheter-related venous thrombosis were measured (study group) and compared with two historical groups study group, 20-cm midline catheters inserted with ultrasound-guided tip location; group 1, 25-cm midline catheters inserted without ultrasound-guided tip location and group 2, 20-cm midline catheters inserted without ultrasound-guided tip location. RESULTS In the study group, ultrasound-guided tip location was easily feasible in 98.9% of patients. Incidence of catheter-related venous thrombosis was 2.42% in control group 1, 9% in control group 2 and 2.62% in the study group. DISCUSSION In the study group and control group 1, the tip was placed in the axillary vein, about 3 cm distal to the clavicle and in the subclavian vein. In control group 2, the tip was probably located at the transition between the axillary and the subclavian vein. It is possible that such position may have been associated with an increased incidence of catheter-related venous thrombosis. CONCLUSION The ideal position of the tip of a midline catheter might be inside the axillary vein, about 3 cm distal to the axillary-subclavian transition or inside the subclavian vein. Ultrasound-guided tip location is safe, inexpensive, easy and potentially useful during midline catheters insertion.INTRODUCTION Hyalofast grafting with microfracture is a new minimally invasive treatment method being proposed for joint cartilage defects. This study was done to measure the clinical efficacy of Hyalofast grafting after microfractures. METHODS Forty-six patients were assessed for knee function using knee injury and osteoarthritis outcome score (KOOS) after undergoing microfracture and Hyalofast grafting surgery. We further divided the 46 patients into a group of 10 patients who had no associated procedures done with the microfracture and Hyalofast grafting surgery. All patients had magnetic resonance imaging (MRI) of the affected knee pre-surgery and two patients had MRI done post-surgery. Due to another unrelated injury, we were also able to obtain further arthroscopic findings of another patient's knee 18 months after microfracture and Hyalofast grafting. CFT8634 RESULTS There was a statistically significant improvement in all categories of the KOOS (symptoms, pain, daily living, sports and quality of life) compared between years 1, 2 and 3 against pre-surgery. For the subgroup of Hyalofast only, there was a statistically significant improvement in symptoms, pain and daily living categories of the KOOS compared between years 1, 2 and 3 against pre-surgery. CONCLUSIONS Our study shows that Hyalofast grafting after microfracture is a viable alternative to treatment for patients with grade 4 cartilage ulcers.We undertook a retrospective study to evaluate minimal 8-year outcomes of 46 trapeziometacarpal joints (46 patients) treated with pyrocarbon implant arthroplasty after partial trapeziectomy for trapeziometacarpal joint osteoarthritis in two different hand surgery units. The mean follow-up interval was 9.5 years (average 113 months with a range 97-144 months). The study showed that pyrocarbon interpositional arthroplasty provided pain relief and high patient satisfaction. All patients experienced a reduction in the DASH score, with an average change of 30 points. The visual analogue scale score, the Kapandji score, and key pinch also showed remarkable improvement. The PyroDisk implant exhibited good longevity, with good implant survival. A review of the literature revealed that the functional outcomes after implant surgery are not superior to more common techniques, such as trapeziectomy with or without ligamentoplasty. Therefore, this is a reliable surgery but may not have added benefits over simpler surgical treatments.
