Serum protein as naturally essential biomacromolecules has recently emerged as a versatile carrier for diagnostic and therapeutic drug delivery for cancer nanomedicine with superior biocompatibility, improved pharmacokinetics and enhanced targeting capacity. A variety of serum proteins have been utilized for drug delivery, mainly including albumin, ferritin/apoferritin, transferrin, low-density lipoprotein, high-density lipoprotein and hemoglobin. As evidenced by the success of paclitaxel-bound albumin nanoparticles (AbraxaneTM), serum protein-based nanoparticles have gained attractive attentions for precise biological design and potential clinical application. In this review, we summarize the general design strategies, targeting mechanisms and recent development of serum protein-based nanoparticles in the field of cancer nanomedicine. Moreover, we also concisely specify the current challenges to be addressed for a bright future of serum protein-based nanomedicines.With aging the immune response is impaired. This immunosenescence, in which an alteration of the redox state of the immune cells appears, is involved in the rate of aging. Since leukocyte function is a good marker of health and predictor of longevity, the effects of daily oral administration of the antioxidant vitamin C (500 mg), or both vitamin C (500 mg) and vitamin E (200 mg) on several blood neutrophil (adherence, chemotaxis, phagocytosis, and superoxide anion levels) and lymphocyte (adherence, chemotaxis, proliferation, interleukin-2 secretion and natural killer activity) functions were studied in healthy elderly men and women. These parameters were analysed before supplementation, after 3 months of supplementation, and 6 months after the end of supplementation. The results showed that vitamin C, in elderly participants, improved the immune functions studied which achieved values close to those of young adults. These effects were maintained in several functions after 6 months without supplementation. Similar effects were found in the elderly supplemented with both vitamin C and E. Thus, a short period of vitamin C or vitamin C and E ingestion, with the doses used, improves the immune function in elderly men and women and could contribute to a healthy longevity.Elderly patients with knee osteoarthritis (OA) are often troubled with joint soreness, swelling, weakness, and pain. Knee intra-articular (IA) injection of autologous platelet rich plasma (PRP) is one of the options that can be used in treating knee OA. However, there are doubts on the effect of PRP when used in treating elderly patients with moderate to severe degrees of knee OA. In this study, 47 elderly patients with moderate degree of knee OA combined with supra-patellar bursitis were recruited. Musculoskeletal ultrasound was used for accurate needle placement for the aspiration of bursa synovial fluid SF followed by PRP injections. this website In group 1, 23 patients received conventional liquid-form IA PRP injections. In group 2, 24 patients received IA injections of thermal oscillation prepared PRP injectants. It was discovered that when the liquid-form PRP was heated up to a temperature of 75 °C and simultaneously oscillated under 200 revolutions per minute (rpm) for 15 min, the end product became paste-form like and with a viscosity similar to that of an anti-cough syrup. Under incubation, the highest number of platelet-derived growth factor (PDGF) was obtained on the 8th day. At one month after the completion of PRP injections, group 2 patients revealed significant decreases in SF total protein concentrations, SF volumes, and Lequesne index values. Proteins associated with inflammation, such as apolipoprotein A-I, haptoglobin, immunoglobulin kappa chain, transferrin, and matrix metalloproteinase also decreased significantly. Therefore, the thermal oscillation preparation method can augment the effectiveness of autologous PRP in treating elderly patients with moderate knee OA. It may be recommended that the PRP injectant should be prepared first using the thermal oscillation method to increase its viscosity, enabling prolonged release of growth factors once it is injected into the knee joint.
Heart failure following myocardial infarction (MI) is a potentially lethal problem with a staggering incidence. The CardiAMP Heart Failure trial represents the first attempt to personalize marrow-derived cell-based therapy to individuals with cell characteristics associated with beneficial responses in prior trials. Before the initiation of the randomized pivotal trial, an open-label "roll-in cohort" was completed to ensure the feasibility of the protocol's procedures.

Patients with chronic post-MI heart failure (NYHA class II-III) receiving stable, guideline-directed medical therapy with a left ventricular ejection fraction between 20 and 40% were eligible. Two weeks prior to treatment, a~5mL bone marrow aspiration was performed to examine "cell potency". On treatment day, a 60mL bone marrow aspiration, bone marrow mononuclear cell (BM MNC) enrichment and transendocardial injection of 200 million BM MNC's was performed in a single, point of care encounter. Patients were then followed to assess clinical outcomes.

The cell potency small volume bone marrow aspirate, the 60mL bone marrow aspirate, and transendocardial injections were well tolerated in 10 patients enrolled. There were no serious adverse events related to bone marrow aspiration or cell delivery. Improvement in 6-min walk distance was observed at 6months (+47.8m, P=0.01) and trended to improvement at 12months (+46.4, P=0.06). Similarly, trends to improved NYHA heart failure functional class, quality of life, left ventricular ejection fraction and recruitment of previously akinetic left ventricular wall segments were observed.

All CardiAMP HF protocol procedures were feasible and well tolerated. Favorable functional, echo and quality of life trends suggest this approach may offer promise for patients with post MI heart failure. The randomized CardiAMP Heart Failure pivotal trial is underway to confirm the efficacy of this approach.

Transcarotid artery revascularization (TCAR) using a flow-reversal neuroprotection system has gained popularity for the endovascular treatment of carotid artery atherosclerotic disease owing to its lower risk of stroke or death compared with transfemoral carotid artery stenting. However, specific risk factors associated with stroke or death complications after TCAR have yet to be defined.

All patients undergoing TCAR for the treatment of asymptomatic or symptomatic atherosclerotic carotid disease were identified between September 2016 and September 2019 in the Vascular Quality Initiative TCAR Surveillance Project. Our primary outcome was 30-day stroke or death. We created a risk model for 30-day stroke or death using multivariable fractional polynomials and internally validated the model using bootstrapping.

During the study period 7633 patients underwent TCAR, of which 4089 (53.6%) were treated for symptomatic and 3544 (46.4%) for asymptomatic disease. The average age of patients undergoing TCAR was 73 CI, 0.39-0.85; P= .005). A 30-point risk prediction model created based on these criteria produced a C statistic of 0.72 and Hosmer-Lemeshow goodness of fit of 0.97. Internal validation demonstrated good discrimination with a bias corrected area under the receiver operating characteristic curve of 0.70 with a calibration slope of 1.00.

This Vascular Quality Initiative TCAR risk score calculator can be used to estimate the risk of stroke or death within 30days of the procedure. Because TCAR is commonly used to treat patients with high surgical risk for carotid endarterectomy, this risk score will help to guide treatment decisions in patients being considered for TCAR.

An arteriovenous fistula (AVF) is the preferred vascular access for chronic hemodialysis; however, the rates of AVF maturation failure and reintervention remain high. We investigated the AVF geometric parameters and their associations with AVF physiologic maturation and reintervention in a prospective multicenter study.

From 2011 to 2016, patients undergoing vein end-to-artery side upper extremity AVF creation surgery were recruited. Contrast-free dark blood and phase-contrast magnetic resonance imaging (MRI) scans were performed using 3.0T scanners to obtain the AVF lumen geometry and flow rates, respectively, at postoperative day 1, week 6, and month 6. The arteriovenous anastomosis angle, nonplanarity, and tortuosity of the fistula were calculated according to the lumen centerlines. AVFs were considered physiologically matured if, using the week 6 MRI data, the flow rate was ≥500mL/min and the minimum vein lumen diameter was ≥5mm. The associations of these geometric parameters with AVF maturation and rce, dialysis status, or diabetes.

In our study, upper arm fistulas had a larger anastomosis angle, were more nonplanar, and had more tortuous veins than forearm fistulas. For upper arm fistulas, a larger nonplanarity angle is associated with a lower rate of reintervention within 1year. Once confirmed, vascular surgeons could consider increasing the nonplanarity angle by incorporating a tension-free gentle curvature in the proximal segment of the mobilized vein to reduce reinterventions when creating an upper arm fistula.

In the present systematic review and meta-analysis, we compared the short- and long-term outcomes of different harvesting and grafting techniques in patients undergoing lower extremity arterial bypass.

We searched multiple electronic databases (up to December 1, 2019) for comparative trials investigating different harvesting and bypass grafting techniques.

We identified a total of 37 studies for our review. Skip incision harvesting showed a similar high primary patency rate (Peto odds ratio [OR], 0.93; 95% confidence interval [CI], 0.83-1.04; P= .20) with continuous incision harvesting and comparable low wound complication rates (relative risk, 1.55; 95% CI, 0.91-2.66; P= .11) with endoscopic harvesting. In situ bypass grafting a long-term patency similar to that of reversed grafting (Peto OR, 1.01; 95% CI, 0.75-1.37; P= .93). However, for femoropopliteal bypass, the reversed bypass grafting group had significantly lower 2-year (Peto OR, 0.63; 95% CI, 0.52-0.78; P< .001) and 5-year (Peto OR, 0.70; 95% CI, 0.
