BACKGROUND: Revaccination after hematopoietic stem cell transplantation (HSCT) is necessary to compensate for the loss of immunological memory. The aims of this study were to evaluate the adherence to revaccination schedule and the humoral immune response to different vaccine antigens in HSCT pediatric and young adult patients. METHODS: Patients submitted to HSCT for over 3 years were recruited. After written informed consent, a questionnaire was filled in, the vaccination card was analyzed, a blood sample was collected and tested by ELISA for diphtheria, Haemophilus influenzae type b (Hib), hepatitis A, hepatitis B, tetanus, measles, rubella and varicella antibodies...

Endogenous adult cardiac regenerative machinery is not capable of replacing the lost cells following myocardial infarction, often leading to permanent alterations in structure-function-mechanical properties. Regenerative therapies based on delivering autologous stem cells within an appropriate 3D milieu could meet such demand, by enabling homing and directed differentiation of the transplanted cells into lost specialized cell populations. Since type I collagen is the predominant cardiac tissue matrix protein, we here optimized the 3D niche which could promote time-dependent evolution of cardiomyogenesis from human bone marrow-derived mesenchymal stem cells (BM-MSC)...

Multivisceral transplantation is the treatment for multiple abdominal organ failure. The patient experiences reduced food intake and absorption of nutrients, contributing to weight loss and decreased muscle mass, reducing functional capacity. A physical and nutritional rehabilitation program based on adequate caloric intake associated with supervised physical exercise seems to support a gain of muscle mass, re-establishing its capacity and functional independence. A rehabilitation program was carried out, consisting of low-intensity aerobic exercise on treadmill, exercises of global strengthening (50% of 1 maximum repetition [1RM], with progressive increase), and nutritional monitoring (oral hypercaloric diet, hyperproteic supplementation daily and after exercise)...

A biological pacemaker is expected to solve the persisting problems of an artificial cardiac pacemaker including short battery life, lead breaks, infection, and electromagnetic interference. We previously reported HCN4 overexpression enhances pacemaking ability of mouse embryonic stem cell-derived cardiomyocytes (mESC-CMs) in vitro. However, the effect of these cells on bradycardia in vivo has remained unclear. Therefore, we transplanted HCN4-overexpressing mESC-CMs into bradycardia model animals and investigated whether they could function as a biological pacemaker...

Colorectal cancer (CRC) is the third most incident cancer worldwide. Most of CRC patients will develop distant metastases, mainly to the liver, and liver resection is the only potential chance for cure. On the other hand, only a small proportion of patients with hepatic CRC metastasis are candidates for upfront liver resection. Liver transplantation (LT) is an attractive option for patients with nonresectable CRC liver metastases (NRCLM) without extrahepatic involvement. Initial experiences with LT for NRCLM achieved very poor outcomes, with a 5-year overall survival (OS) lower than 20%...

Neural progenitor cell (NPC) transplantation has been shown to be beneficial in the ischemic brain. However, the low survival rate of transplanted NPCs in an ischemic microenvironment limits their therapeutic effects. Tumor necrosis factor-alpha (TNF-α) is one of the proinflammatory cytokines involved in the pathogenesis of various injuries. On the other hand, several studies have shown that TNF-α influences the proliferation, survival, and differentiation of NPCs. Our study investigated the effect of TNF-α pretreatment on human NPCs (hNPCs) under ischemia-related conditions in vitro...

BACKGROUND New oral anticoagulants like direct thrombin inhibitors are an attractive alternative to vitamin K antagonists as anticoagulation therapy and can be used in heparin-induced thrombocytopenia. They are convenient in low-risk surgery, as there is no need for bridging with heparins. Patients who need urgent major surgery are at similar risk as on warfarin therapy, which, however, is much higher than in elective procedures. Due to their elimination profiles, these drugs are generally contraindicated in patients with severe renal insufficiency...

The rat model of orthotopic liver transplantation (OLT) is essential for transplant research. It is a very sophisticated animal model and requires a steep learning curve. The introduction of the cuff technique for anastomosis of the portal vein (PV) and infrahepatic vena cava (IHVC) has significantly simplified the transplant procedure in rats. However, due to the short anterior wall of the recipients' suprahepatic vena cava (SHVC), the cuff technique is very difficult to use for the reconstruction of the SHVC...

BACKGROUND: Hand-assisted laparoscopic nephrectomy (HALDN) is currently the procedure of choice for obtaining living donor kidneys for transplantation. In our institution, it has been the standard procedure for 5 years. Previous studies have shown the same function of the graft as that obtained by open surgery, with a lower rate of bleeding and no differences in complications. We sought to demonstrate the experience and safety of HALDN compared with open donor nephrectomy in healthy donors for kidney transplantation...

BACKGROUND: Hepatic immunity, normally protective against neoplasia, is subverted in colorectal liver metastasis (CRLM). Here, we compare the inflammatory microenvironment of CRLM-bearing liver tissue to donor liver. METHODS: Twenty-five patients undergoing resection for CRLM were recruited, 13 of whom developed intrahepatic recurrence within 18 months. Biopsies were obtained from tumour and normal liver tissue adjacent to and distal from, the tumour. Donor liver biopsies were obtained during transplantation...

BACKGROUND: Mycophenolate mofetil (MMF) and mizoribine (MZR) are increasingly used as immunosuppressive agents for organ transplantation and chronic inflammation. We report a patient with rheumatoid arthritis who had an acute inflammatory syndrome triggered by preoperative immunosuppression therapy with both MMF and MZR. CASE REPORT: A 41-year-old woman with IgA nephropathy was referred to our department for living donor renal transplantation. She had rheumatoid arthritis that was adequately treated with prednisolone 5 mg once a day and salazosulfapyridine 2000 mg once a day...

It has been widely suggested that invasion success along broad environmental gradients may be partially due to phenotypic plasticity, but rapid evolution could also be a relevant factor for invasions. Seed and fruit traits can be relevant for plant invasiveness since they are related to dispersal, germination, and fitness. Some seed traits vary along environmental gradients and can be heritable, with the potential to evolve by means of natural selection. Utilizing cross-latitude and reciprocal-transplant experiments, we evaluated the adaptive value of seed thickness as assessed by survival and biomass accumulation in Taraxacum officinale plants...

BACKGROUND AND PURPOSE: In BALB/c mice with transplantable breast tumors, we showed that CD200R1KO mice were cured of local and metastatic growth of EMT6 cells following surgical resection of localized tumor and immunization with irradiated cells along with CpG as adjuvant. On the other hand, wild-type (WT) animals treated in the same fashion develop pulmonary and liver metastases within 20 days of surgery. To develop an in vitro system which would mimic the in vivo model and allow exploration of factors controlling tumor invasion as a precursor to in vivo metastasis, we have developed and characterized a two-phase culture system...

Transplantation of in vitro expanded human corneal endothelial precursors (HCEP) cells using a nanocomposite (D25-NC) gel sheet as supporting material in bovine's cornea has been earlier reported. Herein we report the transplantation of HCEP cells derived from a cadaver donor cornea to three patients using the NC gel sheet. In three patients with bullous keratopathy, one after cataract surgery, one after trauma and another in the corneal graft, earlier performed for congenital corneal dystrophy, not amenable to medical management HCEP cells isolated from a human cadaver donor cornea in vitro expanded using a thermoreversible gelation polymer (TGP) for 26 days were divided into three equal portions and 1...

Massive hemoptysis occurs in a minority of patients with cystic fibrosis, with an annual incidence of 1%. Although rare, massive hemoptysis can be a severe and potentially fatal complication of this disease. Beyond the acute life-threatening event, hemoptysis in patients with cystic fibrosis has been associated with faster decline in lung function, accelerated need for lung transplant, and increased mortality. The bronchial arteries are the culprit vessels in over 90% of cases of hemoptysis. This normally quiescent vascular system undergoes remarkable hypertrophy, collateralization, and angiogenesis before the onset of hemoptysis, introducing numerous pitfalls for the interventionalist...

OBJECTIVES: Cutaneous warts represent a major problem in organ transplant recipients because of their extensive involvement and persistent course. Current therapeutic modalities often fail to achieve a successful response in patients with warts. We experienced a case involving an organ transplant recipient with recalcitrant mosaic warts who presented with complete clearance of lesions in 3 days after thermal spa bathing. Here, we evaluated the efficacy of natural thermal water versus hyperthermic tap water for treatment of recalcitrant hand warts in organ transplant recipients...

OBJECTIVES: Despite surgical advances and effective prophylactic strategies in liver transplant, infection is still a major cause of morbidity and mortality. Up to 80% of liver recipients will develop at least 1 infection during the first year after liver transplant. The spectrum and manifestations of these infections are broad and variable. Their diagnosis and treatment are often delayed because immunosuppressive therapy diminishes inflammatory responses. However, if an infection is not identified early enough and treated properly, it can have devastating consequences...
