Combined en bloc heart and liver transplant.

A combined en bloc heart and liver transplant is a rare form of a combined dual organ transplant in which the donor heart and liver remain connected via the inferior caval vein both during procurement and during the transplant. We present a patient who underwent a combined en bloc heart and liver transplant due to heart failure and cirrhosis, after having previously undergone repair of complex biventricular congenital heart disease.

Combined en bloc heart and liver organ procurement.

A combined heart+liver transplant is the only option for survival in some patients with end-stage combined cardiac and hepatic disease. These patients may suffer from congenital or acquired cardiac disease. The potential aetiologies of the associated hepatic disease are heterogeneous and include systemic disease that impacts the liver as well as venous congestion in patients with functionally univentricular circulation.

COVID-19, public agglomerations and economic effects: Assessing the recovery time of passenger transport services in Brazil.

The outbreak of COVI-19 and the restrictive measures on the mobility of people in Brazil have raised serious concerns about the survival and recovery of passenger transport companies, especially those that generate public agglomerations. There are some policy proposals that aim to recover this set of sectors in the face of the adverse effects of the COVID-19 outbreak. This study contributes to this debate in course and analyzes the economic effects of two scenarios of recovery for this type of transport services in the Brazilian economy up to the end of 2022: (i) one with a 50% recovery until the end of 2021 and (ii) another with a 50% sectorial recovery until June 2022.

Hedonic pricing analysis for semen of dairy bulls in Brazil.

Dairy farming is an important aspect of the Brazilian agricultural sector. The presence of numerous producers has created a large number of jobs in this field, contributing significantly to the rural economy. Artificial insemination (AI), used as one of the main means of reproduction, is increasingly gaining importance in the genetic improvement of animals.

Acute and subacute oral toxicity assessment of dry encapsulated and non-encapsulated green coffee fruit extracts.

The coffee fruit is a high source of bioactive compounds such as phenolic acids and methylxanthines, comprising chlorogenic acids and caffeine, respectively. Extract from this matrix may be used as supplement or active ingredient of functional foods, energy drinks, cosmetics or drugs. Safety of caffeine- and chlorogenic acid-rich encapsulated and non-encapsulated hydroethanolic extracts from green coffee fruit (GCFE) was assessed by acute and subacute toxicity tests.

Modeling arsenic content in Brazilian soils: What is relevant?

Arsenic accumulation in the environment poses ecological and human health risks. A greater knowledge about soil total As content variability and its main drivers is strategic for maintaining soil security, helping public policies and environmental surveys. Considering the poor history of As studies in Brazil at the country's geographical scale, this work aimed to generate predictive models of topsoil As content using machine learning (ML) algorithms based on several environmental covariables representing soil forming factors, ranking their importance as explanatory covariables and for feeding group analysis.

Novel soybean-based high protein bar rich in isoflavones improves insulin sensitivity in diabetic Wistar rats.

This study assessed the effect of whey protein substitution with isolated soy protein in protein bar (PB) formulations at 25% (PB2), 50% (PB3), or 75% (PB1) weight/weight on the proximate and mineral composition, sensory, and antidiabetic properties. Sensory evaluation was conducted within diabetic (DB) and non-diabetic (NDB) consumers by preference ranking and acceptance test. The formulations were analysed in terms of moisture, ash, protein, lipid, carbohydrates, fibers and mineral content.

Organ donation and transplantation from medical students' perspective: introducing the experience from an academic league in Brazil.

Introduction: Medical education is an important factor to decrease the waiting list for transplantation. Reports in the medical literature reveal limited notification of potential organ donors by general physicians. Appropriate information is also needed to increase the availability of potential donors and minimize the waiting list.

Report of initial experience in small bowel transplantation at São José do Rio Preto Medical School Hospital.

Intestinal failure is the patient's inability to maintain hydroelectric and nutritional support by the digestive route, arising from massive enterectomy or diseases in which the bowel is incapable of adequately absorbing fluids and nutrients. Patients with intestinal failure associated with short bowel syndrome (SBS) and with other functional diseases with malabsorption or with total parenteral nutrition-related complications (recurrent sepsis and thrombosis of one or more deep venous accesses) are candidates for small bowel transplantation (SBT), which can be an isolated small bowel, a combined liver and small bowel, or a multivisceral graft. At our institution, three isolated SBTs were performed as our initial experience with this transplant.

An easy and safe model of kidney transplantation in rats.

A technical innovation of a novel ureter implantation technique on rat kidney allograft transplantation is described. The left kidney graft is transplanted heterotopically into the left infrarenal position, using vascular conduits from donor abdominal aorta and inferior vena cava in continuity to renal vessels, to perform arterial and venous end-to-side anastomoses to the recipient vessels. A new ureter implantation technique was employed by placing a purse-string suture around the uretero-vesical anastomosis and ligated at the end of the anastomosis to invaginate the ureter and relieve tension at its junction to the bladder.

The impact of Campath 1H induction in adult liver allotransplantation.

Background: We report our experience with Campath 1H in adult liver allotransplantation.

Methods: Between December 2001 and February 2004, 77 patients underwent liver transplantation using Campath 1H induction and low-dose maintenance tacrolimus immunosuppression. The control group consisted of 50 patients with similar baseline characteristics and the same eligibility criteria, transplanted under our standard Tacrolimus/steroids regimen.

Preliminary experience with alemtuzumab (Campath-1H) and low-dose tacrolimus immunosuppression in adult liver transplantation.

Background: The administration of alemtuzumab (Campath-1H [C1H]; Berlex Laboratories, Montville, NJ) at transplantation prevents a vigorous immune response and is believed to allow a gradual engagement of the host immune system. We report our preliminary experience with C1H and tacrolimus (Tac) immunosuppression in adult liver transplantation.

Methods: We administered C1H and low-dose Tac to 40 adult recipients of cadaveric liver allografts between December 2001 and April 2003.

Study of the development and evolution of neointestine in a rat model.

The implantation of fragmented rat intestinal epithelium into the omentum of syngeneic animals results in the formation of a cyst containing neointestine. The purpose of our project was to study the evolution of this neointestine-containing cyst over time. Harvested jejunum and ileum of neonatal DA rats (6 to 8 days old) was digested with collagenase type XI and dispase at room temperature.

Partial abdominal evisceration, ex vivo resection, and intestinal autotransplantation for the treatment of pathologic lesions of the root of the mesentery.

Background: Resection of lesions of the root of the mesentery with established techniques is difficult and at times impossible because of their proximity to the blood supply of the intestine. Damage of the superior mesenteric vessels necessitates resection of the intestine, resulting in short bowel syndrome and intestinal failure.

Study Design: We describe a surgical technique drawn from our experience in intestinal transplantation in which the root of the mesentery (including the lesion) and the head or the entire pancreas, duodenum, small intestine, and part of the colon are excised en bloc and preserved in a cold solution.

Intestinal transplantation: advances in immunosuppression and surgical techniques.

Campath-1H is being used as induction immunosuppression for intestinal/multivisceral transplantation. Patient and graft survival in this preliminary experience is similar to previous studies but there has been a significant decrease in the incidence and severity of acute rejections without increase of opportunistic infections. Collage of the abdominal wall (transplantation of a composite graft of the abdominal wall) can provide biologic coverage of the newly transplanted abdominal organs if necessary.

Alemtuzumab (Campath-1H) combined with tacrolimus in intestinal and multivisceral transplantation.

Background: We combined alemtuzumab (Campath-1H, Berlex Laboratories, Montville, NJ) and tacrolimus (Tac) immunosuppression for intestinal and multivisceral transplantation.

Materials And Methods: A total of 21 adult patients received 24 grafts: 14 intestinal, nine multivisceral, and one liver-intestinal graft. Alemtuzumab was administered perioperatively in four doses with low-dose Tac (levels 10-15 ng/dL) and no maintenance steroids.

Expression of MUC2 and MUC4 proteins and cytokines: early markers of intestinal graft rejection.

Background: Histopathologic examination (HP) is the primary method of monitoring intestinal graft rejection. Alterations in mucin levels have been demonstrated in bowel diseases. The aim of this study was to detect early markers of intestinal graft rejection based on mucin and cytokine levels.

Donor and recipient pretransplant conditioning with nonlethal radiation and antilymphocyte serum improves the graft survival in a rat small bowel transplant model.

Background: Lymphoid tissue within the intestinal graft require immunomodulatory strategies to prevent graft versus host disease (GVHD) after transplant. Herein, we evaluate the potential advantage of donor-specific bone marrow infusions in donor and or recipient preconditioned with total body irradiation and or antilymphocyte serum (ALS) on the incidence of GVHD and rejection after small bowel transplantation.

Methods: Heterotopic SBTx was performed from DA to Lewis rats and distributed in nine groups: control group G0 (n=4) and G1 (n=6) without irradiation; recipients in G2 (n=4) were given 400 rd although in groups 3 (n=5), G4 (n=6), G6 (n=5), G7 (n=5), and G8 (n=6) with 250 rd.
