RESUMO
The parasites and eggs of helminths, including schistosomes, are associated with factors that can modulate the nature and outcomes of host immune responses, particularly enhancing type 2 immunity and impairing the effects of type 1 and type 17 immunity. The main species of schistosomes that cause infection in humans are capable of generating a microenvironment that allows survival of the parasite by evasion of the immune response. Schistosome infections are associated with beneficial effects on chronic immune disorders, including allergies, autoimmune diseases, and alloimmune responses. Recently, there has been increasing research interest in the role of schistosomes in immunoregulation during human infection, and the mechanisms underlying these roles continue to be investigated. Further studies may identify potential opportunities to develop new treatments for immune disease. In this review, we provide an update on the advances in our understanding of schistosome-associated modulation of the cells of the innate and adaptive immune systems as well as the potential role of schistosome-associated factors as therapeutic modulators of immune disorders, including allergies, autoimmune diseases, and transplant immunopathology. We also discuss potential opportunities for targeting schistosome-induced immunoregulation for future translation to the clinical setting.

Background Return to work with or after a chronic disease is not a very well understood process, influenced by a variety of personal, professional, societal and medical factors. The aim of this study is to identify predictors for return to work 12 months after a solid organ transplant applying a bio-psycho-social model. Methods This study is based on patients included in the Swiss Transplant Cohort Study, a national prospective multicentre cohort, who underwent a first solid organ transplant (kidney, liver, heart, lung). Bio-psycho-social factors were tested and predictors of return to work identified using logistic regression models. Results Among the 636 patients included in the study, 49.8% (317) were employed 12 months post-transplant. The major predictor for returning to work 12 months posttransplant was pre-transplant employment status (OR 10.8). Accordingly, the population was stratified in employed and not employed pre-transplant groups. Age, self-perceived health (6 months post-transplant) and the transplanted organ were significantly associated with post-transplant employment status in both groups. Return to work was influenced by education, depression (6 month post-transplant) and waiting time in the employed pre-transplant group and by invalidity pension in the not employed pre-transplant group. Conclusion Employment status pre-transplant being highly associated with employment status post-transplant, the process promoting return to work should be started well before surgery. Biomedical, psychological and social factors must be taken into account to promote return to work in transplanted patients.

BACKGROUND: The markers of metabolic syndrome can prompt the development of metabolic syndrome and are associated with worse graft function among transplant recipients. Studies have shown that exercise might be effective in reducing incidence rate of metabolic syndrome components in nontransplant patients. However, there is no sufficient evidence to determine whether exercise training is safe or effective for markers of metabolic syndrome among solid organ transplant recipients. OBJECTIVE: To evaluate the safety and efficacy of exercise training programs for risk markers of metabolic syndrome and to further evaluate its long-term effects in solid organ transplant recipients. METHODS: We systematically reviewed all randomized trials comparing the outcomes of exercise training in organ transplant recipients. The Cochrane Library, Joanna Briggs Institute EBP Database, PubMed, Embase, Web of Science Core Collection, ProQuest Health & Medical Complete, and SinoMed databases were searched to June 2017. The meta-analysis was conducted using RevMan 5.3. RESULTS: In total, 13 eligible trails involving 464 patients were included. Recipients who engaged in an exercise program after transplantation showed significant reductions in fasting blood glucose, diastolic blood pressure, triglycerides, and body mass index and a significant increase in high-density lipoprotein. But found no significant changes in new-onset diabetes, systolic blood pressure, total cholesterol, or low-density lipoprotein. CONCLUSION: Exercise training may be a promising intervention for markers of metabolic syndrome in transplant recipients. Further research is required to determine essential aspects of exercise according to organ transplantation type for effects on markers of metabolic syndrome.

BACKGROUND: Our objectives were to describe the physical activity (PA) levels, predictors, barriers, and facilitators to PA in solid organ transplant (SOT) recipients. METHODS: A web-based questionnaire was sent to members of the Canadian Transplant Association including the Physical Activity Scale for the Elderly (PASE), and questions regarding barriers and facilitators of PA. RESULTS: One hundred and thirteen SOT recipients completed the survey. The median PASE score was 164.5 (24.6-482.7). Re-transplantation was the only statistically significant predictor of levels of PA. The most common facilitators of PA included a feeling of health from activity (94%), motivation (88%), social support (76%), knowledge and confidence about exercise (74%) and physician recommendation (59%). Influential barriers were cost of fitness centers (42%), side effects post-transplant or from medications (41%), insufficient exercise guidelines (37%), and feelings of less strength post-transplant (37%). CONCLUSION: There is a large variation in PA levels among SOT recipients. Multiple factors may explain the variance in PA levels in SOT recipients. Identification of facilitators and barriers to PA can inform the development of health and educational promotion strategies to improve participation among SOT recipients with low activity levels.

Due to a continuous expansion of transplantation registers, such as the old-for-old program in Europe, the number of older patients treated with transplantation is increasing. At the same time the perioperative survival rates show a clear increase even in this patient collective (older than 65 years); therefore, the probability that the care of older patients after organ transplantation will be undertaken in the routine practice increases. This article describes the medical characteristics of older patients following organ transplantation. Special emphasis is placed on the management of accompanying diseases as well as possible side effects and interactions of immunosuppressive therapy.

Adjusting to life after transplant can be challenging to pediatric solid organ transplant recipients and their families. In this review, we discuss a number of important factors to consider during the first 2-3 yr after transplant (defined as the "early years"), including transitioning from hospital to home, returning to physical activity, feeding and nutrition, school reentry, potential cognitive effects of transplant, family functioning, and QOL. We highlight steps that providers can take to optimize child and family adjustment during this period.

OBJECTIVE: To assess long-term survival, graft function, and health-related quality of life (QOL) after visceral transplantation. BACKGROUND: Despite continual improvement in early survival, the long-term therapeutic efficacy of visceral transplantation has yet to be defined. METHODS: A prospective cross-sectional study was performed on 227 visceral allograft recipients who survived beyond the 5-year milestone. Clinical data were used to assess outcome including graft function and long-term survival predictors. The socioeconomic milestones and QOL measures were assessed by clinical evaluation, professional consultation, and validated QOL inventory. RESULTS: Of 376 recipients, 227 survived beyond 5 years, with conditional survival of 75% at 10 years and 61% at 15 years. With a mean follow-up of 10 ± 4 years, 177 (92 adults, 85 children) are alive, with 118 (67%) recipients 18 years or older. Nonfunctional social support and noninclusion of the liver in the visceral allograft are the most significant survival risk factors. Nutritional autonomy was achievable in 160 (90%) survivors, with current serum albumin level of 3.7 ± 0.5 gm/dL and body mass index of 25 ± 6 kg/m(2). Despite coexistence or development of neuropsychiatric disorders, most survivors were reintegrated to society with self-sustained socioeconomic status. In parallel, most of the psychological, emotional, and social QOL measures significantly (P < 0.05) improved after transplantation. Current morbidities with potential impact on global health included dysmotility (59%), hypertension (37%), osteoporosis (22%), and diabetes (11%), with significantly (P < 0.05) higher incidence among adult recipients. CONCLUSIONS: With new tactics to further improve long-term survival including social support measures, visceral transplantation has achieved excellent nutritional autonomy and good QOL.

Standardized psychological assessment of candidates for reconstructive hand transplantation (RHT) is a new approach in transplantation medicine. Currently, international guidelines and standardized criteria for the evaluation are not established. Patients suffering from the loss of a hand or an upper extremity have to cope with multiple challenges. For a selected group of patients, RHT represents an option for restoring natural function and for regaining daily living independence. The identification of at-risk patients and those requiring ongoing counseling due to poor coping or limited psychological resources are the primary focus of the psychological assessment. We have developed the 'Innsbruck Psychological Screening Program for Reconstructive Transplantation (iRT-PSP)' which utilizes a semi-structured interview and standardized psychological screening procedures and continuous follow-up ratings. Between January 2011 and October 2011, four candidates were evaluated using the iRT-PSP. Psychological impairments including social withdrawal, embarrassment, reduced self-esteem, and a depressive coping style were identified and poor quality of life was reported. The motivation for transplantation was diverse, depending on many factors such as bi- or unilateral impairment, native or accidental loss of hand, and social integration.

Rehabilitation is receiving increasingly more attention from the medical community in the management of individuals' pre- and post-organ transplantation. A cross-sectional descriptive survey was administered to all known transplant programs across Canada to explore the availability, characteristics, and barriers of rehabilitation programs pre- and post-heart, lung, kidney, and liver transplantation. Of the 58 programs surveyed, 35 agreed to participate (nine heart, six lung, 13 kidney, seven liver), and six refused for a response rate of 71%. Twelve transplant programs that offered rehabilitation were identified (six heart, five lung, one liver). All rehabilitation programs identified included aerobic exercises, strength training, and education and involved a multidisciplinary team. The Six Minute Walk Test and the Medical Outcomes Short Form-36 questionnaire were the most commonly used outcome measures. In kidney and liver transplant programs, over 50% of respondents from these programs cited lack of funding, shortage of health care personnel, and a low volume of patients in a centralized region as barriers to providing rehabilitation programs. Rehabilitation can play an integral role in pre- and post-transplantation management, and barriers to access and provision of rehabilitation for organ transplant populations should be examined further.

PURPOSE: The purpose was to evaluate the amount of extrusion and clinical and radiographic outcomes of meniscal allograft transplantation (MAT) after use of a modified Pollard method to measure the size of the meniscus. METHODS: We analyzed 36 patients who underwent MAT between September 2002 and June 2008. Eighteen patients had preoperative allograft sizing by the conventional Pollard sizing method, and the other 18 had the size measured by our modified method, reducing the total size of the graft by 5% from the Pollard method. The mean follow-up period was 31.4 months (range, 24 to 36 months). We compared the absolute amount of extrusion and the relative percentage of extrusion between the 2 groups. We also compared the Lysholm knee score, amount of joint space narrowing on radiographs, and Kellgren-Lawrence grade. RESULTS: The absolute amount of extrusion did not differ significantly between the 2 groups. However, the mean relative percentage of extrusion was lower in the modified Pollard group (P = .037). The mean Lysholm knee score increased in all patients, but there was no significant difference between the 2 groups. There was no significant difference in terms of radiographic outcomes. CONCLUSIONS: Reducing the graft size by 5% from the Pollard method decreases the percentage of meniscal extrusion after MAT without any adverse outcome clinically or radiographically. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

INTRODUCTION: The objectives of our dissemination project were (1) to disseminate the evidence supporting exercise training in solid organ transplantation to exercise professionals, health-care professionals, physicians, and directors of transplant programs in order to enhance their ability to apply evidence to practice and (2) to build a community of exercise professionals and researchers across Canada. METHODS: We used the 5-step Patient-Centered Outcomes Research Institute model for knowledge translation to guide our project: (1) evidence assessment, (2) audience and partner identification, (3) dissemination, (4) implementation, and (5) evaluation. After meeting with experts in the field, conducting a literature review, and identifying an appropriate audience, we took our presentations on the road across Canada. RESULTS: We visited 10 transplant centers and held interactive knowledge translation sessions in each center. To provide sustainability and to facilitate the adoption of the research evidence, we founded the Canadian Network for Rehabilitation and Exercise for Solid Organ Transplant Optimal Recovery network and created its website. CONCLUSIONS: Our project raised awareness of the importance of exercise among many health professionals in Canada and built a community of exercise professionals and researchers in the field of transplantation through the rehabilitation network. It also led to the creation of online resources that will facilitate the implementation of rehabilitation programs in transplant centers.

INTRODUCTION: Despite the well-known benefits of exercise during the pretransplantation and post-transplantation phases, adherence to active lifestyles is still reduced. The aim of the present study is to evaluate how many patients who have received organ transplants and candidates for organ transplantation carry out physical or sports activities in order to increase adherence to an active lifestyle. METHODS: The patients who agreed to participate in the study were interviewed about their lifestyle habits by the staff at the nephrology, dialysis, and hepatology units of the Emilia-Romagna region. The interview investigated the patient's lifestyle (active or sedentary) and type of physical activity (walking, cycling, gardening, gym at least 3 to 40 minutes, 2 to 3 times per week) or sport (training > 2 times per week) routinely practiced. RESULTS: We collected 1138 interviews from patients on the waiting list (n = 159) for organ transplant, those with kidney transplants (n = 756), and those with liver transplants (n = 223) monitored in the Emilia-Romagna hospitals (regional patients 67%, extraregional 33%). Eighty-four patients on the waiting list for a transplant (kidney) were sedentary, 75 practiced physical activity, and 10 of 75 physically active patients practiced sport. Four hundred fifteen patients with kidney transplants were sedentary, 341 practiced physical activity, and 31 of 341 physically active patients practiced sport. Among patients with liver transplants, 56 were sedentary, 167 practiced physical activity, and 20 of 167 physically active patients played sport. CONCLUSIONS: In-line with the general population, we confirmed a high tendency toward a sedentary lifestyle (44% of respondents) among patients with organ transplants and those on waiting lists for organ transplants. Including a prescription for physical exercise as part of the therapeutic regimen can be useful for changing lifestyles during the pre- and post-transplantation period.

Ovarian function with regular menstrual cycles is usually restored in women of reproductive age after solid organ transplantation. The number of pregnancies reported in these patients increases gradually. Pregnancy is always considered high risk, and not properly planned may lead to serious complications. The best for the patient is to conceive in a period of good general health and good stable graft function, after appropriate preparation and not later than five years after transplantation. Immunosuppressive regimen should be modified before conception. Sirolimus and mycophenolate mofetil should be excluded. The blood levels of immunosuppressive agents should be regularly controlled during the whole pregnancy. The rate of successful pregnancies isn approximately 95% in graft recipients. Increased incidence of preterm labor, anemia and intrauterine growth restriction is observed compared with general population. Organ transplantation itself is not an indication for cesarean section and vaginal delivery is recommended as the best for the patient, the graft and the newborn. Breast feeding is believed to be contraindicated in women on immunosuppressive therapy, however no adverse effects were reported in children of graft recipients who decided to breast feed. The rate of congenital malformations in newborns is approximately 3-4% and does not differ from the rate seen in general population. The rate of perinatal deaths decreased beneath 0.8% in recent reports. Jaundice, hyperglycemia and hyperkalemia, observed more frequently in newborns of graft recipients, are mild and in most cases do not have any clinical implications.

INTRODUCTION: Better family adjustment following pediatric solid organ transplantation has been associated with a number of beneficial medical and psychosocial outcomes. Yet few studies have examined which pretransplant variables are associated with posttransplant family adjustment. This information can aid in identifying families that may need support going into the transplantation process and those who are at lower risk of worse posttransplant adjustment. METHOD: The sample included 66 parents of children with solid organ transplants and 22 children with solid organ transplants. Information regarding demographic factors, parent and child emotional functioning, and child social support was collected during the child's pretransplant evaluation and information on family adjustment was collected 6 months after transplantation. RESULTS: Results indicated that pretransplant demands such as worse parent and child emotional functioning were related to worse family adjustment 6 months after transplantation. Pretransplant capabilities (i.e., higher family income, parent education level, parent marital status, child social support) were not associated with posttransplant family adjustment. DISCUSSION: Pretransplant family demands such as parent and child emotional functioning, as opposed to family capabilities, should be assessed by family health care team members prior to transplantation because they may be related to worse family adjustment after the transplant. We offer recommendations for ways to assess and, if indicated, intervene upon pretransplant family demands in an effort to decrease the risk of worse posttransplant family adjustment.

BACKGROUND: Following the positive experience of the national project "A transplant...and now it's time for sport," the Transplant Reference Center of the Emilia-Romagna Region has pursued the promotion of pre- and post-transplant physical exercise by developing a network. METHODS: The path involved the transplant centers and operative units (UU.OO) who wanted to target transplant and waiting list patients, who are clinically stable, to perform personalized exercise through a program (supervised or not) prescribed by a specialist in sports medicine. With the collaboration of the Collective Prevention and Public Health Service, the network was established, consisting of the sports medicine centers and the gyms that promote health for adapted physical activity (PS-AMA). To implement the network, training courses for all the professionals involved (doctors, nurses, exercise specialists) and operational meetings in the transplant centers-nephrology units with patients' associations have been organized. RESULTS: To date, there are 14 transplant centers and UU.OO, 9 sports medicine centers, and 45 PS-AMA involved in this network. Seven training courses were organized with the participation of 193 health professionals. Since January 2016, there have been 65 transplanted patients and 5 patients on the waiting list who practice the prescribed exercise. Of these, 45 carry out supervised exercise in PS-AMA; 25 perform autonomous exercise. Each patient is monitored every 6 months. No problems related to the exercise performance were recorded. CONCLUSIONS: The development of a network of professionals and associations is the key element to raise awareness of physical activity among transplanted and waiting-for-transplant patients, reducing the pathologies associated with a sedentary lifestyle.

PURPOSE: The feasibility of hand allotransplantation has been demonstrated. The purpose of the article is to report the (1) functional return, (2) psychosocial outcomes, (3) clinical and histological assessment for rejection, (4) complications, and (5) graft survival in the 2 American hand transplant recipients. METHODS: We present 2 patients 106 and 81 months, respectively, after unilateral transplantation of an allogeneic hand and forearm. We analyzed clinical course, number of rejection episodes, adverse events, function of the allograft, and quality of life. Clinical laboratory results, biopsy histology, and patient clinical examinations were used to compare the clinical course. Standard hand function tests were used to evaluate function. Psychological interviews were used to assess acceptance and quality of life. RESULTS: Our patients have allograft survival with improvements in intrinsic muscle activity, total active motion and return of functional grip, pinch strength, and sensibility. Rejection episodes were restricted primarily to the first 6 months after transplantation, and all responded to treatment. The major posttransplantation complications were a cytomegalovirus infection in patient 1 and osteonecrosis of the hip requiring both hips to be replaced, 1 at year 4 and the other at year 6, as well as transient immunosuppression-related diabetes in patient 2. Recently we have weaned both patients off maintenance steroids. Current Carroll scores are fair for patient 1 (72/99) and fair for patient 2 (55/99), although patient 2 has not had good recovery of intrinsic function. Both patients are back at work and report an excellent quality of life at nearly 9 and 7 years, respectively, after transplantation. CONCLUSIONS: Our intermediate long-term results of hand transplants have demonstrated functional return similar to that of replants. Graft survival and quality of life after hand transplantation has far exceeded initial expectations. We conclude that allogeneic hand transplant is feasible and holds promise as a treatment modality for catastrophic upper extremity loss. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
