Infectious complications remain a major cause of morbidity and mortality among transplant recipients. Urinary tract infection (UTI) is the most common infectious complication in kidney transplant recipients with a reported incidence from 25% to 75%, varies widely likely due to differences in definition, diagnostic criteria, study design, and length of observation. We sought reviews the incidence and importance of urinary tract infection on graft survival, the microbiology with special emphasis on multidrug resistant microorganisms, the therapeutic management of UTI and the prophylaxis of recurrent UTI among solid organ transplant recipients, highlighting the need for prospective clinical trials to unify the clinical management in this population.

This study reports the clinical complication and infection rates of an active pediatric IT program that has never utilized bowel decontamination in either the donor or the recipient. All patients undergoing IT from 2003 to 2015 at a single pediatric IT center were reviewed. Post-transplant surgical, infectious, and immunosuppressive complications are reported. There were 52 patients who underwent IT during the study period. Among these patients, 4% developed a postoperative abscess, one developed an enteric fistula (2%), and one had an enteric or anastomotic leak (2%). The rate of any bacterial infection was 90% in the first year, with a wound infection rate of 23%. Any fungal infection occurred in 25% of patients. Any viral infection occurred in 75% of patients. Gastrointestinal viruses were diagnosed in 52% of patients, and cytomegalovirus infections occurred in 17%. Rejection rates were 39% at any time post-transplant (isolated 44% and 35% for multivisceral patients). At this center in which no bowel decontamination was used, rates of surgical complications, infections, and rejection were similar to those reported by other centers. These findings suggest bowel decontamination may provide no significant benefit in this population of high-risk transplant patients. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The frequency of B19 infection in renal transplant donors and recipients was studied to determine the significance of active viral infection in the development of anemia. Serum, plasma, and peripheral blood leukocyte samples of 47 renal transplant donors, 38 recipients with anemia (Group 1), and 25 without anemia (Group 2) after renal transplantation were evaluated for the presence of anti-B19 specific antibodies (ELISA) and B19 DNA (nPCR). Active persistent B19 infection after renal transplantation was detected in 12 of the 38 in the Group 1 (10 had reactivation and 2 primary infection), and none of the recipients in the Group 2 had it. Of the 12 recipients in the Group 1, 10 were seropositive and 2 seronegative before renal transplantation; 10 received the transplants from the seropositive and 2 from seronegative donors. rHuEPO therapy-resistant severe anemia was detected only in the recipients with active B19 infection after renal transplantation in the Group 1 (7/12). The logistic regression analysis revealed a significant relationship between active B19 infection and severe anemia (OR, 0.039; 95% CI, 0.006-0.257; P=0.001). Active B19 infection was documented only in the anemic recipients and could be associated with the development of severe anemia after renal transplantation. This allows us to recommend concurrent screening for viral DNA in plasma and detection of anti-B19 IgM class antibodies. To find the association between B19 infection and the development of anemia, further investigations are necessary.

To evaluate complications and success of mandibular reconstruction with free fibula flaps, iliac crest flaps, and forearm flaps with reconstruction plates and to evaluate dental rehabilitation after these reconstructions. Eighty-three patients with segmental mandibular defects were included. Correlation analyses were used to determine the relationship between reconstruction type and clinical parameters with recipient-site complications and success. The dental rehabilitation was evaluated in successfully reconstructed survivors. Multivariate analyses showed significant correlations between flap type and success (P < .0001). Of the patients, 51 (61%) were alive 2 years after the reconstruction. Mandibular reconstruction with a free forearm flap and reconstruction plate was associated with higher complication rates at the recipient site and higher failure rates compared with reconstruction with free vascularized bone flaps. Of the 32 successfully reconstructed survivors, 14 (44%) had a complete dental rehabilitation, of which 10 had dental implants and 4 did not. Only 6 (29%) of the edentulous survivors ultimately had an implant-supported prosthesis. Reconstruction of the mandible with a free vascularized bone flap is superior to reconstruction with a free forearm flap with a reconstruction plate. Complete dental rehabilitation was reached in fewer than half of the surviving patients. Copyright © 2012 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc.

Antithymocyte antibody (ATA) remains the most commonly used induction immunosuppressive agent in renal transplantation (RT). To date, few case reports of ATA-induced coagulopathy exist. We performed a single-center, retrospective analysis of renal transplant recipients (RTRs) who underwent RT followed by ATA therapy between 2007 and 2011. The protocol used for deceased donor and unrelated living donor recipient immunosuppression was Thymoglobulin (TMG), methylprednisolone, Cellcept, Prograf, and Rapamune. In related living donor recipients, Simulect (SIM) was substituted for TMG. The international normalized ratio (INR) was routinely checked on days 0 and 2, and thereafter at the discretion of the surgeon. RTRs were transfused packed red blood cells (PRBCs) or fresh frozen plasma (FFP) at the discretion of the surgeon. During the study period, 257 RTs were performed at our institution. The following 18 RTR were excluded: simultaneous kidney and pancreas transplant recipients (4), RTRs on warfarin at the time of admission (2), RTRs who received OKT3 (2), and RTRs with INR ≥ 1.2 at the time of admission (10). Of the remaining 239 RTR, 208 (87%) underwent TMG induction therapy; 31 RTR (13%) underwent SIM induction therapy. The mean INR peaked in both groups on day 4 but was higher in TMG recipients (TMG 1.35, SIM 1.20). FFP was transfused in 65 TMG (31%) and 3 SIM (10%) recipients (P = .01); PRBCs were transfused in 88 TMG (44%) and 6 SIM (19%) recipients (P = .02). No patients returned to the operating room for bleeding complications within 7 days of RT. Patient age, gender, ethnicity, and diabetes status were not statistically significant factors in the development of coagulopathy. TMG administration is associated with coagulopathy. Using an INR screening protocol and an aggressive transfusion protocol, bleeding complications associated with coagulopathy can be avoided in this higher-risk group. Copyright © 2013 Elsevier Inc.

Due to the increasing number and improved survival of lung transplant recipients, radiologists should be aware of the imaging features of the postoperative complications that can occur in such patients. The early treatment of complications is important for the long-term survival of lung transplant recipients. Frequently, HRCT plays a central role in the investigation of such complications. Early recognition of the signs of complications allows treatment to be initiated earlier, which improves survival. The aim of this pictorial review was to demonstrate the CT scan appearance of pulmonary complications such as reperfusion edema, acute rejection, infection, pulmonary thromboembolism, chronic rejection, bronchiolitis obliterans syndrome, cryptogenic organizing pneumonia, post transplant lymphoproliferative disorder, bronchial dehiscence and bronchial stenosis.

The aim of this study was to document vascular complications that occurred following cadaveric and living donor kidney transplants in order to assess the overall incidence of these complications at our center as well as to identify possible risk factors. In a retrospective cohort study, 1500 consecutive renal transplant recipients who received a living or cadaveric donor kidney between December 1988 and July 2006 were evaluated. The study was performed at the Nemazee Hospital, Shiraz, Iran. The assessment of the anatomy and number of renal arteries as well as the incidence of vascular complications was made by color doppler ultrasonography, angiography, and/or surgical exploration. Clinically apparent vascular complications were seen in 8.86% of all study patients (n = 133) with the most frequent being hemorrhage (n = 91; 6.1%) followed by allograft renal artery stenosis (n = 26; 1.7%), renal artery thrombosis (n = 9; 0.6%), and renal vein thrombosis (n = 7; 0.5%). Vascular complications were more frequent in recipients of cadaveric organs than recipients of allografts from living donors (12.5% vs. 7.97%; P0.017). The occurrence of vascular complications was significantly more frequent among recipients of renal allografts with multiple arteries when compared with recipients of kidneys with single artery (12.3% vs. 8.2%; P0.033). The same was true to venous complications as well (25.4% vs. 8.2%; P< 0.001). Our study shows that vascular complications were more frequent in allografts with multiple renal blood vessels. Also, the complications were much less frequent in recipients of living donor transplants. (author)

The aim of this study was to investigate the risk factors for access site-related complications after transradial coronary angiography (CAG) or percutaneous coronary intervention (PCI). Transradial PCI has been shown to reduce access site-related bleeding complications compared with procedures performed through a femoral approach. Although previous studies focused on risk factors for access site-related complications after a transfemoral approach or transfemoral and transradial approaches, it is uncertain which factors affect vascular complications after transradial catheterization. We enrolled 500 consecutive patients who underwent transradial CAG or PCI. We determined the incidence and risk factors for access site-related complications such as radial artery occlusion and bleeding complications. Age, sheath size, the dose of heparin and the frequency of PCI (vs. CAG) were significantly greater in patients with than without bleeding complications. However, body mass index (BMI) was significantly lower in patients with than without bleeding complications. Sheath size was significantly higher and the frequency of statin use was significantly lower in patients with than without radial artery occlusion. Multiple logistic analysis revealed that sheath size [odds ratio (OR) 5.5; P strategy that could prevent radial artery occlusion after transradial procedures.

Marrow transfusions into normal recipients

Brecher, G.

During the past several years we have explored the transfusion of bone marrow into normal nonirradiated mice. While transfused marrow proliferates readily in irradiated animals, only minimal proliferation takes place in nonirradiated recipients. It has generally been assumed that this was due to the lack of available proliferative sites in recipients with normal marrow. Last year we were able to report that the transfusion of 200 million bone marrow cells (about 2/3 of the total complement of marrow cells of a normal mouse) resulted in 20% to 25% of the recipient's marrow being replaced by donor marrow. Thus we can now study the behavior of animals that have been transfused (donor) and endogenous (recipient) marrow cells, although none of the tissues of either donor or recipient have been irradiated. With these animals we hope to investigate the nature of the peculiar phenomenon of serial exhaustion of marrow, also referred to as the limited self-replicability of stem cells

To compare the donor site complication rate and length of hospital stay following the harvest of bone from the iliac crest, calvarium, or mandibular ramus. Ninety-nine consecutively treated patients were included in this retrospective observational single-center study. Iliac crest bone was harvested in 55 patients, calvarial bone in 26 patients, and mandibular ramus bone in 18 patients. Harvesting of mandibular ramus bone was associated with the lowest percentages of major complications (5.6%), minor complications (22.2%), and total complications (27.8%). Harvesting of iliac crest bone was related to the highest percentages of minor complications (56.4%) and total complications (63.6%), whereas harvesting of calvarial bone induced the highest percentage of major complications (19.2%). The length of the hospital stay was significantly influenced by the choice of donor site (P = .003) and age (P = .009); young patients with the mandibular ramus as the donor site had the shortest hospital stay. Harvesting of mandibular ramus bone was associated with the lowest percentage of complications and the shortest hospital stay. When the amount of bone to be obtained is deemed sufficient, mandibular ramus bone should be the first choice for the reconstruction of maxillofacial defects.

Dual kidney transplantation (DKT) is a largely accepted strategy to enlarge the donor pool. Niguarda Hospital started this program in December 2010, and 38 DKT have been performed. In our series, we included recipients older than those in the other series published in literature. The aim of this study was to know if our recipient selection criteria for DKT are safe. We reviewed our data base of DKT and analyzed recipients' medical history, surgical technique, post-operative complications, graft survival, morbidity, and mortality. We then compared our results with the literature. From December 2010 to April 2015, 38 DKT were performed in Niguarda Hospital. Delayed graft function was present in 21 recipients. Explantation of both kidneys was performed in 1 patient and explantation of 1 kidney in 6 patients. Post-operative complications were present in 8 patients. Five patients returned to hemodialysis after DKT. One recipient died of medical post-operative sepsis. The mean follow-up was 24 months. Graft survival and patient survival were 86.84% and 97.93%, respectively. Compared with the literature, our series had similar mortality and morbidity rates, even if recipients' age was higher than in other series. The strategy of DKT allocation in elderly recipients is safe. Further studies have to be performed to optimized selection of the recipients for DKT not to disadvantage younger patients in the transplant waiting list and to improve the technique of organ evaluation and preservation to refine graft allocation.

Full Text Available BACKGROUND Serum paraoxonase is an enzyme synthesised in the liver. It is known to prevent atherosclerosis by inhibiting oxidation of lowdensity lipoprotein. Renal transplant recipients have increased tendency for developing atherosclerosis and cardiovascular disease. Reduced activity of serum paraoxonase contributes to accelerated atherosclerosis and increased cardiovascular complications in these patients. The aim of this study was to estimate serum paraoxonase activity in renal transplant recipients and compare it with healthy controls. MATERIALS AND METHODS 30 renal transplant recipients and 30 age and sex matched healthy controls were taken for the study. Serum paraoxonase activity, blood urea, serum creatinine and uric acid were estimated in these groups. The serum paraoxonase activity was correlated with urea, creatinine and uric acid levels. RESULTS Serum paraoxonase activity was reduced in renal transplant recipients compared to healthy controls. There was a negative correlation between paraoxonase activity and the levels of urea, creatinine and uric acid levels. CONCLUSION In this study, the paraoxonase activity was reduced in renal transplant recipients compared to controls. The increased cardiovascular disease in these patients could be due to reduced paraoxonase activity.

Appendicitis is a common cause of emergency surgery that in the population undergoing organ transplantation presents a rare incidence due to late diagnosis and treatment. To report the occurrence of acute appendicitis in a cohort of liver transplant recipients. Retrospective analysis in a period of 12 years among 925 liver transplants, in witch five cases of acute appendicitis were encountered. Appendicitis occurred between three and 46 months after liver transplantation. The age ranged between 15 and 58 years. There were three men and two women. The clinical presentations varied, but not discordant from those found in non-transplanted patients. Pain was a symptom found in all patients, in two cases well located in the right iliac fossa (40%). Two patients had symptoms characteristic of peritoneal irritation (40%) and one patient had abdominal distention (20%). All patients were submitted to laparotomies. In 20% there were no complications. In 80% was performed appendectomy complicated by suppuration (40%) or perforation (40%). Superficial infection of the surgical site occurred in two patients, requiring clinical management. The hospital stay ranged from 48 h to 45 days. Acute appendicitis after liver transplantation is a rare event being associated with a high rate of drilling, due to delays in diagnosis and therapy, and an increase in hospital stay.

Full Text Available Objective. Evaluate the prevalence and outcomes of urinary tract infection (UTI among renal transplant recipients. Methods. A secondary analysis of the Nationwide Inpatient Sample 2009–2011 was conducted. Survey-weighted multivariable regression analyses were used to examine the impact of UTI on transplant complications, total charges, and length of stay. Results. A total of 1,044 renal transplant recipients, representing a population estimate of 49,862, were included in the study. UTI was most common in transplant recipients with hypertension (53% and prevalence was noted to be 28.2 and 65.9 cases per 1,000 for men and women, respectively. UTI increased the likelihood of transplant complications (182% for men, 169% for women. Total charges were 28% higher among men as compared to 22% among women with UTI. Such infection also increased the length of stay by 87% among men and 74% among women. Discussion. UTI in renal transplant recipients was associated with prolonged length of stay, total charges, and increased odds of transplant complications. Interventions to prevent UTI among such patients should be a priority area for future research and practice.

Clostridium difficile infection (CDI) is a considerable health issue in the United States and represents the most common healthcare-associated infection. Solid organ transplant recipients are at increased risk of CDI, which can affect both graft and patient survival. However, little is known about the impact of CDI on health services utilization posttransplantation. We examined hospital-onset CDI from 2012 to 2014 among transplant recipients in the University HealthSystem Consortium, which includes academic medical center-affiliated hospitals in the United States. Infection was five times more common among transplant recipients than among general medicine inpatients (209 vs 40 per 10 000 discharges), and factors associated with CDI among transplant recipients included transplant type, risk of mortality, comorbidities, and inpatient complications. Institutional risk-standardized CDI varied more than 3-fold across high-volume hospitals (infection ratio 0.54-1.82, median 1.04, interquartile range 0.78-1.28). CDI was associated with increased 30-day readmission, transplant organ complications, cytomegalovirus infection, inpatient costs, and lengths of stay. Total observed inpatient days and direct costs for those with CDI were substantially higher than risk-standardized expected values (40 094 vs 22 843 days, costs $198 728 368 vs $154 020 528). Further efforts to detect, prevent, and manage CDI among solid organ transplant recipients are warranted. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

Solid-organ transplant recipients may require percutaneous dilational tracheotomy because of prolonged mechanical ventilation or airway issues, but data regarding its safety and effectiveness in solid-organ transplant recipients are scarce. Here, we evaluated the safety, effectiveness, and benefits in terms of lung mechanics, complications, and patient comfort of percutaneous dilational tracheotomy in solid-organ transplant recipients. Medical records from 31 solid-organ transplant recipients (median age of 41.0 years [interquartile range, 18.0-53.0 y]) who underwent percutaneous dilational tracheotomy at our hospital between January 2010 and March 2015 were analyzed, including primary diagnosis, comorbidities, duration of orotracheal intubation and mechanical ventilation, length of intensive care unit and hospital stays, the time interval between transplant to percutaneous dilational tracheotomy, Acute Physiology and Chronic Health Evaluation II score, tracheotomy-related complications, and pulmonary compliance and ratio of partial pressure of arterial oxygen to fraction of inspired oxygen. The median Acute Physiology and Chronic Health Evaluation II score on admission was 24.0 (interquartile range, 18.0-29.0). The median interval from transplant to percutaneous dilational tracheotomy was 105.5 days (interquartile range, 13.0-2165.0 d). The only major complication noted was left-sided pneumothorax in 1 patient. There were no significant differences in ratio of partial pressure of arterial oxygen to fraction of inspired oxygen before and after procedure (170.0 [interquartile range, 102.2-302.0] vs 210.0 [interquartile range, 178.5-345.5]; P = .052). However, pulmonary compliance results preprocedure and postprocedure were significantly different (0.020 L/cm H2O [interquartile range, 0.015-0.030 L/cm H2O] vs 0.030 L/cm H2O [interquartile range, 0.020-0.041 L/cm H2O); P = .001]). Need for sedation significantly decreased after tracheotomy (from 17 patients [54.8%] to

Review the acute and late results of percutaneous transluminal coronary angioplasty (PTCA) in heart transplant recipients and examine the factors predictive of restenosis. Coronary graft disease (CGD) is the main factor responsible for late graft loss. Medical treatment, surgical revascularization, or retransplantation gives only suboptimal results in this regard. Therefore, PTCA has been attempted in this situation. More than 332 heart transplantations in our institution have been performed since 1992, the date of the first PTCA in our patients. We are currently in charge of 450 patients. All the characteristics, procedure-related information, and clinical outcome of patients needing PTCA were assessed by review of each patient's clinical records. All coronary angiograms were reviewed by an independent cardiologist. Since 1992, 53 coronary sites have been dilated in the course of 39 procedures in 29 patients. Indication for PTCA was asymptomatic angiographic coronary graft disease in 35 sites (64.8%), angina in 9 (16.6%), silent ischemia in 2 (3.7%), acute myocardial infarction in 1 (1.8%), and CHF in 7 (12.9%). Primary success ( 50%) was 32.5% (14/43). Mean follow-up was 1.27 year +/- 1.2 (SD). Five deaths (17. 2%) occurred in follow-up and were all in relation to coronary graft disease. Mean time separating PTCA from death was 0.9 year +/- 1.3 (SD). We also sought to look at factors predictive of restenosis. By multivariate analysis, a positive recipient's serology for cytomegalovirus (CMV) before the graft was the only factor found protective against restenosis (odds ratio 22.4; confidence interval 1.1 to 443.4). PTCA in heart transplant recipients allows a high level of primary success with a low periprocedural-complication rate. Restenosis rate seems equivalent to restenosis rate in native coronary arteries. Mortality during follow-up is increased in this population and is the consequence of a high level of coronary events.

Numerous spontaneous pregnancies have been reported in renal transplant recipients; however, only a few pregnancies after the use of assisted reproductive techniques. The authors report a case of renal transplant recipient with secondary infertility who delivered a healthy baby without any complications. The report highlights the importance of minimal stimulation protocol during ovarian stimulation, single embryo transfer, and the need for multispecialty care for these patients. To the best of the authors' knowledge, the present report is the first such case from India and also the second in the world to report a blastocyst transfer among renal transplant recipients.

Full Text Available Objective: Clinical application of autologous fat grafting (AFG is quickly expanding. Despite the widely acceptance, long-term survival rate (SR of AFG remains a question not yet solved. Meanwhile, although rare, severe complications related to AFG including vision loss, stroke even death could be seen in the literature. Data Sources: A comprehensive research of PubMed database to June 2013 was performed according to guidelines of the American Society of Plastic Surgeons Fat Graft Task Force Assessment Methodology. Articles were screened using predetermined inclusion and exclusion criteria. Study Selection: Data collected included patient characteristics, surgical technique, donor site, recipient site, graft amount, and quantified measurement methods. Patient cohorts were pooled, and SR was calculated. All the severe complications were also summarized according to the different clinical characteristics. Results: Of 550 articles, 16 clinical articles and 10 animal studies met the inclusion criteria and provided quantified measurement methods. Totally, 596 patients were included. SR varied from 34% to 82% in breast and 30-83% in the facial area. Nude mice were applied to investigate human fat grafting SR (38.3-52.5% after 15 weeks. Rabbits were commonly used to study animal AFG SR (14.00-14.56% after 1-year. Totally, 21 severe complications were reported, including death (2, stroke (10, vision loss (11, 8 of which accompanied with stroke, sepsis (3, multiple abscess (1 and giant fat necrotic cyst (2. Ten of these complications happened within 10 years. Conclusions: There is no unified measurement method to evaluate fat graft SR until now and no clinical evidence to show better SR according to different donor and recipient cite. Body mass index change between pre- and postoperation may be the bias factor in evaluating fat SR. Fat embolisms of the ophthalmic artery and the middle cerebral artery are the most severe complication of AFG and still lack

Body and earlobe piercing are common practices in the USA today. Minor complications including infection and bleeding occur frequently and, although rare, major complications have been reported. Healthcare professionals should be cognizant of the medical consequences of body piercing. Complications vary depending on the body-piercing site, materials used, experience of the practitioner, hygiene regimens, and aftercare by the recipient. Localized infections are common. Systemic infections such as viral hepatitis and toxic shock syndrome and distant infections such as endocarditis and brain abscesses have been reported. Other general complications include allergic contact dermatitis (e.g. from nickel or latex), bleeding, scarring and keloid formation, nerve damage, and interference with medical procedures such as intubation and blood/organ donation. Site-specific complications have been reported. Oral piercings may lead to difficulty speaking and eating, excessive salivation, and dental problems. Oral and nasal piercings may be aspirated or become embedded, requiring surgical removal. Piercing tracts in the ear, nipple, and navel are prone to tearing. Galactorrhea may be caused by stimulation from a nipple piercing. Genital piercings may lead to infertility secondary to infection, and obstruction of the urethra secondary to scar formation. In men, priapism and fistula formation may occur. Women who are pregnant or breastfeeding and have a piercing or are considering obtaining one need to be aware of the rare complications that may affect them or their child. Though not a 'complication' per se, many studies have reported body piercing as a marker for high-risk behavior, psychopathologic symptoms, and anti-social personality traits. When it comes to piercing complications, prevention is the key. Body piercers should take a complete medical and social history to identify conditions that may predispose an individual to complications, and candidates should choose a

Liver transplant is considered to be the last-resort treatment approach for pediatric patients with end-stage liver disease. Despite the remarkable advance in survival rates, liver transplant remains an intricate surgery with significant morbidity and mortality. Early diagnosis of complications is crucial for patient survival but is challenging given the lack of specificity in clinical presentation. Knowledge of the liver and vascular anatomy of the donor and the recipient or recipients before surgery is also important to avoid complications. In this framework, radiologists play a pivotal role on the multidisciplinary team in both pre- and postoperative scenarios by providing a road map to guide the surgery and by assisting in diagnosis of complications. The most common complications after liver transplant are (a) vascular, including the hepatic artery, portal vein, hepatic veins, and inferior vena cava; (b) biliary; (c) parenchymal; (d) perihepatic; and (e) neoplastic. The authors review surgical techniques, the role of each imaging modality, normal posttransplant imaging features, types of complications after liver transplant, and information required in the radiology report that is critical to patient care. They present an algorithm for an imaging approach for pediatric patients after liver transplant and describe key points that should be included in radiologic reports in the pre- and postoperative settings.

Full Text Available Abstract Background Vascular complications, such as HAT, are an important cause of graft loss and recipient mortality. We aimed to characterize post-transplant thrombotic events in a cohort of liver transplant recipients, and identify independent risk factors for these complications. Methods We conducted a thrombophilic study of 293 orthotopic liver transplants performed in the Digestive Surgery Department of the 12 de Octubre Hospital (Madrid, Spain between January 2001 and December 2006. Results The most frequent post-transplant thrombotic events were HAT (9% and PVT (1.7%. The one variable associated with post-transplant thrombotic event was a high fibrinogen level in the global cohort of liver transplantation. But toxicity as event post-OLT has been associated with post-transplant thrombotic event in the retrospective group and high fibrinogen level and low protein C levels were associated post-transplant thrombotic event in the prospective group. Liver disease relapse (HR 6.609, p In conclusion, high fibrinogen and decreased protein C levels were associated with allograft thrombosis. Further studies are required in order to assess the clinical relevance of these parameters in prospective studies and to study the effect of anticoagulation prophylaxis in this group of risk.

Even though preoperative marking of the stoma area is considered important for the prevention of postoperative complications, not all healthcare institutions have universally adopted this practice. A multicenter, retrospective, descriptive study was conducted to determine the effect of stoma site marking on stomal and peristomal complications. The 1-year study included 748 patients (408 [54.5%] male, mean age 56.60 ± 16.73 years) from eight stomatherapy units in Turkey. Patient data, including age, gender, diagnosis, type of surgery, history of preoperative stoma site marking, person performing the marking, and postoperative complications, were obtained from patient records, abstracted, and analyzed. Cancer was the reason for the operation in 545 (72.9%) of the cases. In 287 patients (38.4%), the stoma and wound care nurse and/or surgeon marked the stoma area; this occurred 1 day before or on the day of surgery according to Wound Ostomy Continence Nurses Society and American Society of Colon and Rectal Surgeons recommendations. Stomal/ peristomal complications developed in 248 (33.2%) persons; the most frequently observed complications in patients were parastomal skin problems (136, 48.7%), mucocutaneous separation (52, 18.6%), and retraction (31, 11.1%). The rate of complications was higher among patients whose stoma site was not marked than among those whose stoma site was marked (22.9% and 46%, respectively; P stoma area should be marked preoperatively in all planned surgical interventions in order to reduce the risk of postoperative complications. Additional prospective and experimental studies on effectiveness of preoperative stoma site marking should be conducted with larger sample groups.

The sural artery and vein were used successfully as recipient vessels in nine patients who required free flap reconstruction about the knee. The anatomy of the sural vessels and the potential advantages of their use as free flap recipients are reviewed and discussed. Indications include popliteal vessels that are absent or severely damaged, as determined by preoperative angiography. No anastomotic complications were encountered in this series, indicating that the sural artery and vein can be used successfully as recipient vessels.

Objective: To assess short-term outcomes after lung transplantation with organs procured following brain death. Methods: Between April 2015 and July 2016, all 17 recipients after lung transplantation using organs from brain death donors (DBD) at Department of Thoracic Surgery, Shanghai Pulmonary Hospital, Tongji University School of Medicine were enrolled in this study. All patients were male, aging (60±7) years, including 11 chronic obstructive pulmonary disease, 5 idiopathic pulmonary fibrosis, 1 silicosis. Seventeen donors were 16 males and 1 female, with 10 traumatic brain injury, 5 cerebrovascular accident and 2 sudden cardiac death. Of 17 recipients receiving DBD lung transplant, 16 were single lung transplant. Data were collected including intubation duration of mechanical ventilation, hospital length of stay, incidence of pulmonary infection bronchus anastomosis complications, primary graft dysfunction (PGD), and acute rejection, bronchiolitis obliterans syndrome (BOS) as well as mortality of 90-day after lung transplantation. Results: Median duration of intubation were 2 (2) days ( M ( Q R )) in recipients after lung transplantation. The incidence of pulmonary infection and bronchus anastomosis complications were 15/17 and 5/17, respectively. Median length of stay in hospital were 56 (19) days. The ratio of readmission 1 month after discharge were 10/17. Mortality of 90-day post-transplant were 2/17. The incidence of PGD and BOS were 1/17 and 2/17, respectively. Conclusion: Recipients with DBD lung transplantation have an acceptable survival during short-term follow-up, but with higher incidences of complications related to infection post-transplantation.

Full Text Available Soluble form of CD40L is platelet activating factor, which is a marker of inflammation and thrombosis. Elevated levels of sCD40L before the heart transplantation are associated with the risk of early development of cardiova- scular complications. The study included 54 patients who had received heart transplants. All recipients received a triple heart immu- nosuppressive therapy, including methylprednisolone, mycophenolate mofetil and cyclosporine A (20 recipients or methylprednisolone, mycophenolate mofetil and tacrolimus (34 recipients. Patients were not differed by age, gender, etiology of heart failure before heart transplantation (p > 0,05. In the first group of transplant recipients, the relative risk of cardiovascular events with high sCD40L levels before transplantation was 3 2 (95% CI 1,4; 12,0. In the second group of recipients, respectively, 2.69 (95% CI 1,1; 8,5. SCD40L level after heart transplan- tation was significantly higher for patients receiving cyclosporine (P < 0.05. Increasing concentrations of sCD40L are associated with a higher incidence of cardiovascular complications. 

Development and Validation of a Preprocedural Risk Score to Predict Access Site Complications After Peripheral Vascular Interventions Based on the Vascular Quality Initiative Database

2016-01-01

Full Text Available Purpose: Access site complications following peripheral vascular intervention (PVI are associated with prolonged hospitalization and increased mortality. Prediction of access site complication risk may optimize PVI care; however, there is no tool designed for this. We aimed to create a clinical scoring tool to stratify patients according to their risk of developing access site complications after PVI. Methods: The Society for Vascular Surgery’s Vascular Quality Initiative database yielded 27,997 patients who had undergone PVI at 131 North American centers. Clinically and statistically significant preprocedural risk factors associated with in-hospital, post-PVI access site complications were included in a multivariate logistic regression model, with access site complications as the outcome variable. A predictive model was developed with a random sample of 19,683 (70% PVI procedures and validated in 8,314 (30%. Results: Access site complications occurred in 939 (3.4% patients. The risk tool predictors are female gender, age > 70 years, white race, bedridden ambulatory status, insulin-treated diabetes mellitus, prior minor amputation, procedural indication of claudication, and nonfemoral arterial access site (model c-statistic = 0.638. Of these predictors, insulin-treated diabetes mellitus and prior minor amputation were protective of access site complications. The discriminatory power of the risk model was confirmed by the validation dataset (c-statistic = 0.6139. Higher risk scores correlated with increased frequency of access site complications: 1.9% for low risk, 3.4% for moderate risk and 5.1% for high risk. Conclusions: The proposed clinical risk score based on eight preprocedural characteristics is a tool to stratify patients at risk for post-PVI access site complications. The risk score may assist physicians in identifying patients at risk for access site complications and selection of patients who may benefit from bleeding avoidance

Preoperative stoma site marking and counseling aim to improve patients' rehabilitation and adaptation to a new medical condition. Objective studies are needed to provide evidence of the impact of care by stoma therapists. Key quality indicators include patients' quality of life, independence, and complication rates as affected by the variable modes of stoma site marking and planning. The aim of this study was to evaluate the impact of preoperative stoma site marking on patients' quality of life, independence, and complication rates. : A validated stoma quality-of-life questionnaire was used as the main assessment tool. Complications were noted on regular postoperative visits. This is a single-center, clinical study. The study was conducted at the Rambam Health Care Campus in Haifa, Israel. Rambam Health Care Campus is a tertiary university hospital. All patients who underwent an elective stoma creation between 2006 and 2008 were included. Evaluated parameters included demographics, stoma type, marking status, complication rates, quality of life, and independence parameters. : One hundred five patients (60 men and 45 women) were included, of whom 52 (49.5%) were preoperatively marked and 53 (50.5%) were not marked. Sixty stomas (57%) were permanent, and 45 (43%) stomas were temporary. The quality of life of patients whose stoma sites were preoperatively marked was significantly better than that of the unmarked patients (p stoma type. Preoperative stoma site marking is crucial for improving patients' postoperative quality of life, promoting their independence, and reducing the rates of postoperative complications. The role of the enterostomal therapist is very important in the ostomates' pre- and postoperative care.

New-onset diabetes mellitus (NODM) after liver transplantation (LT) occurs with increased frequency in recipients with hepatitis C virus (HCV). We compared the incidence and risk factors for NODM in HCV vs non-HCV recipients. Among 24,956 liver recipients, 18,741 without pretransplantation diabetes were identified. NODM-free survival was analyzed using Kaplan-Meier and log-rank tests, and risk factors for NODM were examined using multivariate Cox regression analysis. The overall incidence of NODM was 13.0% at 1 year after LT. At 1, 2, 3, and 5 years after LT, incidence of NODM in HCV recipients was 14.4%, 4.3%, 3.1%, and 3.5%, respectively, compared with 11.9%, 3.5%, 3.2%, and 6.4%, respectively, in non-HCV recipients. HCV recipients had a higher risk of NODM than non-HCV recipients (hazard ratio 1.17 [1.09-1.27], P diabetes mellitus. Risk factors in non-HCV recipients were male recipient, BMI, and recipients with nonalcoholic steatohepatitis diagnosis. HCV recipients have a higher incidence and more risk factors for NODM than non-HCV recipients. Early identification of modifiable risk factors will assist clinical interventions to prevent NODM complications after LT. Copyright © 2016 Elsevier Inc. All rights reserved.

To investigate blood cultures of deceased donors and report the confirmed transmission of bacterial infection from donors to liver recipients. We retrospectively studied the results of blood cultures among our donation after cardiac death (DCD) donors and calculated the donor-derived bacterial infection rates among liver recipients. Study participants underwent liver transplantation between January 1, 2010 and February 1, 2017. The study involved a total of 67 recipients of liver grafts from 67 DCD donors. We extracted the data of donors' and patients' characteristics, culture results and clinical outcomes, especially the post-transplant complications in liver recipients, from electronic medical records. We analyzed the characteristics of the donors and the corresponding liver recipients with emphasis put on donor-derived infections. Head trauma was the most common origin of death among our 67 DCD donors (46.3%). Blood taken prior to the procurement operation was cultured for 53 of the donors, with 17 episodes of bloodstream infections developing from 13 donors. The predominant organism isolated from the blood of donors was Gram-positive bacteria (70.6%). Only three (4.5%) of 67 liver recipients developed confirmed donor-derived bacterial infections, with two isolates of multidrug-resistant Klebsiella pneumoniae and one isolate of multidrug-resistant Enterobacter aerogenes. The liver recipients with donor-derived infections showed relation to higher crude mortality and graft loss rates (33.3% each) within 3 mo post transplantation, as compared to those without donor-derived infections (9.4% and 4.7%, respectively). All three liver recipients received appropriate antimicrobial therapy. Liver recipients have high occurrence of donor-derived infections. The liver recipients with donor-derived multidrug-resistant Enterobacteriaceae infections can have good outcome if appropriate antimicrobial therapy is given.

Radial artery (RA) access for PCI has a lower incidence of vascular access-site (VAS) complications than the femoral artery (FA) approach. However, even for default radial operators certain patients are intervened upon from the FA. We examined the demographics and incidence of VAS complications when default radial operators resort to the FA for PCI. The demographics and VAS complications were compared by access site retrospectively for all PCI cases performed by default radial operators (n=1,392). A modified ACUITY trial definition of major VAS complication was used. FA puncture occurred in 25.2% (351/1,392) of cases. Patients were more likely to be female, older and weigh less than patients undergoing PCI from the RA. The FA procedure was likely to be more complex with larger sheaths, more left main stem, graft and multivessel intervention, and there was a greater proportion of emergency cases. Despite increased case complexity, glycoprotein inhibitors were used less frequently in femoral cases (26.5% vs. 36.8%, prisk factors for access-site bleeding are disproportionately high in the population requiring FA puncture by default radial operators, and as a result such patients have a high rate of vascular access-site complications.

Due to the increasing number and improved survival of lung transplant recipients, radiologists should be aware of the imaging features of the postoperative complications that can occur in such patients. The early treatment of complications is important for the long-term survival of lung transplant recipients. Frequently, HRCT plays a central role in the investigation of such complications. Early recognition of the signs of complications allows treatment to be initiated earlier, which improves survival. The aim of this pictorial review was to demonstrate the CT scan appearance of pulmonary complications such as reperfusion edema, acute rejection, infection, pulmonary thromboembolism, chronic rejection, bronchiolitis obliterans syndrome, cryptogenic organizing pneumonia, post transplant lymphoproliferative disorder, bronchial dehiscence and bronchial stenosis.

BACKGROUND Nonsteroidal anti-inflammatory drugs (NSAIDs) and analgesics are the most commonly used drugs and are increasingly available over-the-counter (OTC). In certain groups of patients, including kidney transplant recipients, their use may be complicated by adverse effects or drug interactions. The aim of our study was to assess the causes and frequency of OTC NSAIDs or analgesics use, as well as the awareness of related side effects. MATERIAL AND METHODS We enrolled 94 randomly selected kidney transplant recipients, who represented 5% of all kidney transplant recipients at our center. An anonymous survey consisting of 23 multiple-choice questions was administered voluntarily and anonymously. RESULTS In all, 63% of study patients confirmed taking the OTC painkillers; 22% of these patients took these drugs at least several times a week, and 4% took these drugs daily. For 38% of the study kidney transplant recipients, NSAIDs or analgesics were reported to be the only way to manage their pain. In addition, 30% of study patients were unaware of the risks associated with these drugs, despite the fact that 89% of the study patients consider physicians the best source of information. CONCLUSIONS Our study found that 63% of kidney transplant recipients regularly took OTC painkillers and 30% were unaware of the potential adverse effects. This necessitates continuous, ongoing education of kidney transplant recipients about the risks of OTC NSAIDs or analgesics use.

Full Text Available Abstract Background Portal vein thrombosis is a frequent complication in end-stage cirrhosis with a considerable peri-operative risk for liver transplant candidates. We aimed to characterize the pre-transplant portal vein thrombosis in a cohort of liver transplant recipients, and to identify independent risk factors for this complication. Methods 380 consecutive primary orthotopic liver transplants were performed in the Digestive Surgery Department of “12 de Octubre” Hospital (Madrid, Spain, between January 2001 and December 2006. The main risk factors considered were smoking, obesity, metabolic disorders, previous immobility, surgery or trauma, nephrotic syndrome, associated tumor, inflammatory disease, neoplasm myeloprolipherative. Furthermore we have reported genetic thrombophilia results for 271 recipients. Results Sixty-two (16.3% patients developed pre-transplant portal vein thrombosis and its presence had no impact in the overall survival of liver recipients. Obesity was the only independent risk factor for pre-transplant portal vein thrombosis. Conclusion We recommend close control of cardiovascular factors in patients with liver cirrhosis in order to avoid associated thrombosis.

2005-01-01

Sirolimus is an immunosuppressive drug that has been used during the past few years. Sirolimus is indicated in rescue therapies and to reduce the secondary toxic effects of calcineurin inhibitors. This drug has been associated with infrequent but severe pulmonary toxicity. Cases of interstitial pneumonitis, bronchiolitis obliterans with organizing pneumonia, and alveolar proteinosis have been described. We describe a case of pulmonary toxicity associated with the use of sirolimus in a 59-yr-old liver transplant recipient. We also review all reported cases of sirolimus-associated lung toxicity among liver transplantation recipients, with the intention of understanding the risk factors, the clinical picture and the outcomes of this complication. Five cases have been reported since January 2000, including the present case. Clinical presentation is similar, with fever, dyspnoea, fatigue, cough, and hemoptysis. Discontinuation of the drug led to resolution of clinical and radiographic findings. Sirolimus-induced pulmonary toxicity is a serious condition and should be considered in the differential diagnosis of liver recipients presenting with respiratory findings. Discontinuation of the drug is associated with resolution of the pulmonary compromise

Bacteremias among renal transplant recipients are more frequent as a result of immunosuppression. They are considered extremely high-risk because they are correlated with decreased allograft and recipient survival. All episodes of bacteremia among renal transplant recipients were documented following review of medical records, from January 2010 to May 2013. In total 26 episodes of bacteremia were observed in 22 patients. Gram negative bacteremia was identified in 73% (19/26) cases. Pathogens according to their frequency were the following Escherichia coli (6/26, 23%), Klebsiella pneumonia (5/26, 19%), Pseudomonas aeruginosa (3/26, 11%), Staphylococcus epidermidis (3/26, 11%), Acinetobacter baumanni (2/26, 7.7%), Enterococcus faecalis (2/26, 7.7%). The first trimester post renal transplantation 18 episodes (69%) of bacteremia were presented that were not correlated to indwelling urinary catheter or stent. Positive urinary culture with the same pathogen was recognized in 13 patients. All recipients manifested fever, eight recipients had leucocytosis and three cases were complicated by septic shock. Immediate resuscitation with intravenous fluids and non-nephrotoxic antibiotic regimen was initiated. Acute renal allograft dysfunction (defined as an increase in serum creatinine more than 0.5 mg/dL from baseline) was observed in five patients and was restored following infection resolution. Increased prevalence of bacteremia in renal transplant recipients is attributed to immunosuppression and usually bacteremic episodes follow urinary tract infection. The commonest pathogens are Gram negative bacteria with E. coli the most frequent. Early detection and proper management are important as bacteremia affects renal allograft and recipient survival.

External volume expansion prepares recipient sites to improve outcomes of fat grafting. For patients receiving radiotherapy after mastectomy, results with external volume expansion vary, and the relationship between radiotherapy and expansion remains unexplored. Thus, the authors developed a new translational model to investigate the effects in chronic skin fibrosis after radiation exposure. Twenty-four SKH1-E mice received 50 Gy of β-radiation to each flank and were monitored until fibrosis developed (8 weeks). External volume expansion was then applied at -25 mmHg to one side for 6 hours for 5 days. The opposite side served as the control. Perfusion changes were assessed with hyperspectral imaging. Mice were euthanized at 5 (n = 12) and 15 days (n = 12) after the last expansion application. Tissue samples were analyzed with immunohistochemistry for CD31 and Ki67, Masson trichrome for skin thickness, and picrosirius red to analyze collagen composition. All animals developed skin fibrosis 8 weeks after radiotherapy and became hypoperfused based on hyperspectral imaging. Expansion induced edema on treated sides after stimulation. Perfusion was decreased by 13 percent on the expansion side (p External volume expansion temporarily reduces perfusion, likely because of transient ischemia or edema. Together with mechanotransduction, these effects encourage a proangiogenic and proliferative environment in fibrotic tissue after radiotherapy in the authors' mouse model. Further studies are needed to assess these changes in fat graft retention.

Living-related liver transplantation was developed in the context of deceased donor organ shortage, which is particularly acute for pediatric recipients. This retrospective study analyzes the surgical technique and complications in the first 100 pediatric liver transplantation using left segmental liver grafts from living donors, performed at Saint-Luc University Clinics between July 1993 and April 2002. Pre-operative evaluation in donors and recipients, analysis of the surgical technique, and postoperative complications were reviewed. After a median follow-up period of 2526 days, no donor mortality was encountered, with a minimal morbidity and no long-term sequelae. At one and five yr post-transplantation, the actuarial patient survival rates were 94% and 92%, the corresponding figures being 92% and 89% for graft survival. The incidences of portal vein and hepatic artery thromboses, and of biliary complications were 14%, 1%, and 27%, respectively. Living-related liver transplantation in children constitutes an efficient therapy for liver failure to face the increased demand for liver grafts. Donor morbidity was kept to acceptable incidence, and surgical technique in the recipient needs to be tailored to minimize postoperative complications.

Kidney transplantation is the treatment of choice for a significant number of patients with end-stage renal disease. Although immunosuppression therapy improves graft and patient's survival, it is a major risk factor for infection following kidney transplantation altering clinical manifestations of the infectious diseases and complicating both the diagnosis and management of renal transplant recipients (RTRs). Existing literature is very limited regarding osteomyelitis in RTRs. Sternoclavicular osteomyelitis is rare and has been mainly reported after contiguous spread of infection or direct traumatic seeding of the bacteria. We present an interesting case of acute, bacterial sternoclavicular osteomyelitis in a long-term RTR. Blood cultures were positive for Streptococcus mitis, while the portal entry site was not identified. Magnetic resonance imaging of the sternoclavicluar region and a three-phase bone scan were positive for sternoclavicular osteomyelitis. Eventually, the patient was successfully treated with Daptomycin as monotherapy. In the presence of immunosuppression, the transplant physician should always remain alert for opportunistic pathogens or unusual location of osteomyelitis.

Organ transplant recipients have a higher incidence of skin cancer. This risk is magnified over time and with continued exposure to immunosuppression. Skin cancer in nonwhite patients is associated with greater morbidity and mortality owing to diagnosis at a more advanced stage, which suggests that nonwhite organ transplant recipients are at even higher risk. To describe demographic and clinical factors and the incidence of skin cancer in nonwhite organ transplant recipients. We performed a retrospective medical record review of patients who were organ transplant recipients (154 were white and 259 nonwhite [black, Asian, Hispanic, Pacific Islander]) seen from November 1, 2011, to April 18, 2016 at an academic referral center. Variables were analyzed and compared between racial groups, including sex, age, race/ethnicity, Fitzpatrick type, type and location of skin cancer, type of organ transplanted, time to diagnosis of skin cancer after transplantation, and history of condyloma acuminata and/or verruca vulgaris. Most of the 413 patients (62.7%) evaluated were nonwhite organ transplant recipients; 264 were men, and 149 were women. Their mean (SD) age was 60.09 (13.59) years. Nineteen skin cancers were identified in 15 patients (5.8%) representing 3 racial/ethnic groups: black (6 patients), Asian (5), and Hispanic (4). All squamous cell carcinomas in blacks were diagnosed in the in situ stage, located on sun-protected sites, and occurred in patients whose lesions tested positive for human papilloma virus (HPV) and/or who endorsed a history of condyloma acuminata or verruca vulgaris. Most skin cancers in Asians were located on sun-exposed areas and occurred in individuals who emigrated from equatorial locations. Nonwhite organ transplant recipients are at risk for developing skin cancer posttransplantation. Follow-up in a specialized transplant dermatology center and baseline total-body skin examination should be part of posttransplantation care in all organ

Pregnancy and parenting have been part of human life throughout history and liver transplant recipients are not any exception. This paper reports successful pregnancies in two liver transplant recipients in Iran. The first case was a 34-year old woman who had undergone orthotopic liver transplantation (OLT) at Shiraz Namazi Educational Hospital in 2002. She decided to get pregnant seven years after the operation. During pregnancy, immunosuppressive therapy continued, except Mycophenolate Mofetil which has an absolute contra-indication in pregnancy. The patient was followed up during pregnancy by the transplant team as well as a gynecologist. She faced no significant complications and the liver function was stable during pregnancy. She later underwent a Cesarean section in the 38(th) week of gestation and the newborn was a healthy girl weighing 2480g with an Apgar score of 8 at the time of birth. There were no evidences of prematurity or structural abnormalities in the newborn. The second case was a 31-year old primipara who had received an orthotopic liver transplant (OLT) in Shiraz in 2002. She had a smooth pregnancy without any complications and the newborn was a boy weighing 3100g with Apgar scores of 8 and 10 at the time of birth and 5 minutes thereafter, respectively. As the number of transplant recipients is growing along with the number of recipients who are in their fertility years, it is vital to ensure a proper medical care by a coordinated multidisciplinary team during pregnancy.

Warfarin discontinuation with heparin bridging is a common practice in patients receiving warfarin prior to elective coronary angiography (CAG). The uninterrupted warfarin strategy has been suggested to be alternative option for patients with high thromboembolic risk. Therefore, we aimed to assess the safety of elective transfemoral CAG during uninterrupted warfarin therapy compared to heparin bridging. This study was a randomized open-label design with blinded event evaluation. The 110 consecutive patients (age ≥ 18 years) receiving warfarin before the planned transfemoral CAG were randomly assigned to either heparin bridging or uninterrupted warfarin with targeted INR (2.0-3.0). The primary outcome was the incidence of major vascular access site complications. The baseline characteristics were comparable between two groups (mean age was 60.1 ± 7.8 years, 49 males). The mean INR on the day of CAG of heparin bridging and uninterrupted warfarin groups was 1.2 ± 0.3 and 2.2 ± 0.5 (P warfarin patients (P = 0.243). The total vascular access site complications occurred in 6 (10.9%) heparin-bridging and one (1.8%) uninterrupted warfarin patients (P = 0.113). No patient developed either other bleeding or thromboembolic events during 7 days after CAG. We demonstrated that an uninterrupted warfarin strategy did not increase vascular access site complications in patients undergoing transfemoral CAG compared to heparin bridging therapy. Due to the safety and the ease of uninterrupted warfarin strategy, this approach should be encouraged in patients receiving long-term warfarin who undergo elective transfemoral CAG. © 2017, Wiley Periodicals, Inc.

The role of the pharmacist in the management of kidney transplant recipients

Full Text Available Pharmacists may play a key role on the multidisciplinary transplant team. This article describes the development and current status of pharmacists in the management of transplant recipients in the United States. Traditionally, pharmacists played an important support role in transplant medicine. This role has been expanded to include direct patient care for the avoidance, detection, and/or treatment of side effects from the polypharmacy necessary in the management of these complex patients. Pharmacists provide pre- and post-transplant education to transplant recipients to enhance adherence to complicated medical regimens and thereby reduce readmission to hospital and unscheduled, costly visits to urgent care centers and/or hospital emergency departments.

New-onset diabetes mellitus (NODM) is a common complication after liver transplantation (LT). The small ubiquitin-like modifier 4 (SUMO4) rs237025 polymorphism has been reported to be associated with type 2 diabetes mellitus (T2DM). In this study, we aimed to evaluate the association of donor and recipient SUMO4 rs237025 polymorphisms with NODM and the long-term consequences of NODM after LT. A total of 126 liver transplant patients were enrolled in the study. One single nucleotide polymorphism, SUMO4 rs237025, was genotyped in both donors and recipients. Both donor and recipient SUMO4 rs237025 polymorphisms were found to be significantly associated with NODM after LT. In multivariate analysis, recipient age>50 years, tacrolimus trough concentrations>10ng/mL at 1month after LT, donor and recipient rs237025 genetic variant, and the combined donor and recipient rs237025 genetic variant were independent predictive factors of NODM. Area under the receiver operating characteristic curve (AUROC) analysis indicated the higher predictive ability of the model containing combined donor and recipient rs237025 polymorphisms than the clinical model (p=0.046). Furthermore, Kaplan-Meier survival analysis demonstrated that NODM was related to significantly poorer patient survival in comparison with non-NODM patients (p=0.041). Both donor and recipient SUMO4 rs237025 polymorphisms contribute to the development of NODM after LT and NODM is a frequent complication that negatively affects patient survival. Copyright © 2017.

Extracorporeal shock wave lithotripsy (ESWL) has evolved as a standard treatment modality for calculi of the upper urinary tract. Noninvasive ESWL shows rare life-threatening complications. Herein we have reported the case of a liver transplant recipient who developed severe renal hemorrhage after ESWL of a renal calculus. Transfusion of erythrocytes and platelets led to anaphylactic shock with acute renal failure requiring intensive care. The patient fully recovered shortly thereafter and was discharged home with a residual left kidney stone measuring 8 mm. A 55-year-old man with a single left kidney underwent ESWL due to symptomatic left nephrolithiasis. He had undergone successful liver transplantation 11 years earlier. At the time of ESWL his liver functions were normal and his serum creatinine level was 1.3 mg/dL. Two weeks before the treatment a double pigtail ureteral stent was inserted because of a symptomatic left hydronephrosis. Several hours after ESWL treatment the patient complained of left-sided flank pain. An ultrasound revealed a large subcapsular hematoma of the left kidney, which was confirmed using abdominal computed tomography (CT). With the patient being hemodynamically stable, we opted for conservative management. Despite postinterventional complications, the patient made a fast recovery. ESWL is a noninvasive, safe, and efficient method to treat renal calculi. Patients who are at risk for hemorrhage should undergo close postinterventional monitoring, including red blood cell count and renal ultrasound. Copyright © 2010 Elsevier Inc. All rights reserved.

Infectious complications are, with rejection, the main cause of morbidity and mortality in heart transplantation recipients. Adequate management of these patients requires an adequate knowledge of risk factors, of most common infectious syndromes and of relevant microorganism, as long as of their resistance pattern. Among the first group, we may mention lower respiratory tract infections, mediastinitis and meningitis, and among the microorganisms, Citomegalovirus, Aspergillus and Toxoplasma gondii. The impressive development of diagnostical techniques and of prophylactic and therapeutical possibilities suggest the convenience of a multidisciplinar approach to these complications.

Patients with short telomere syndromes and pulmonary fibrosis have increased complications after lung transplant. However, the more general impact of donor and recipient telomere length in lung transplant has not been well characterized. This was an observational cohort study of patients who received lung transplant at a single center between January 1st 2012 and January 31st 2015. Relative donor lymphocyte telomere length was measured and classified into long (third tertile) and short (other tertiles). Relative recipient lung telomere length was measured and classified into short (first tertile) and long (other tertiles). Outcome data included survival, need for modification of immunosuppression, liver or kidney injury, cytomegalovirus reactivation, and acute rejection. Recipient lung tissue telomere lengths were measured for 54 of the 79 patients (68.3%) who underwent transplant during the study period. Donor lymphocyte telomeres were measured for 45 (83.3%) of these recipients. Neither long donor telomere length (hazard ratio [HR] = 0.58, 95% confidence interval [CI], 0.12-2.85, p = 0.50) nor short recipient telomere length (HR = 1.01, 95% CI = 0.50-2.05, p = 0.96) were associated with adjusted survival following lung transplant. Recipients with short telomeres were less likely to have acute cellular rejection (23.5% vs. 58.8%, p = 0.02) but were not more likely to have other organ dysfunction. In this small cohort, neither long donor lymphocyte telomeres nor short recipient lung tissue telomeres were associated with adjusted survival after lung transplantation. Larger studies are needed to confirm these findings.

We present a case of ocular syphilis after a renal transplantation involving progressive vision loss without clinically identifiable ocular disease. Electroretinography showed signs of ischemia, especially in the internal retina. A serological test was positive for syphilis. Lumbar puncture revealed lymphocytic meningitis and a positive serologic test for syphilis in the cerebrospinal fluid. The patient was treated with penicillin, and had a quick vision improvement. In the case of transplant recipients, clinicians should always consider the diagnosis of ocular syphilis in cases with unexplained visual acuity decrement, as this condition may cause serious complications if not treated.

Is there a need for preoperative imaging of the internal mammary recipient site for autologous breast reconstruction?

Science.gov (United States)

Rozen, Warren M; Alonso-Burgos, Alberto; Murray, Alice C A; Whitaker, Iain S

2013-01-01

Preoperative imaging of recipient-site vasculatur in autologous breast reconstruction may potentiate improved outcomes through the identification of individual variations in vascular architecture. There are a range of both normal and pathologic states which can substantially affect the internal mammary vessels in particular, and the identification of these preoperatively may significantly affect operative approach. There are a range of imaging modalities available, with ultrasound particularly useful, and computed tomography angiography (CTA) evolving as a useful option, albeit with radiation exposure. The benefits of CTA must be balanced against its risks, which include contrast nephrotoxicity and allergic reactions, and radiation exposure. The radiation risk with thoracic imaging is substantially higher than that for donor sites, such as the abdominal wall, with reasons including exposure of the contralateral breast to radiation (with a risk of contralateral breast cancer in this population 2 to 6 times higher than that of primary breast cancer, reaching a 20-year incidence of 15%), as well as proximity to the thyroid gland. Current evidence suggests that although many cases may not warrant such imaging because of risk, the benefits of preoperative CTA in selected patients may outweigh the risks of exposure, prompting an individualized approach.

Older kidney transplant recipients are susceptible to cognitive impairment, frailty, comorbidities, immunosuppression-related complications, and chronic graft failure, however, there has been limited focus on their concerns and expectations related to transplantation. This study aims to describe the perspectives of older kidney transplant recipients about their experience of kidney transplantation, self-management, and treatment goals to inform strategies and interventions that address their specific needs. Face-to-face semistructured interviews were conducted with 30 kidney transplant recipients aged 65-80 years from five renal units in Australia. Transcripts were analyzed thematically. Six themes were identified: restoring vitality of youth (with subthemes of revived mindset for resilience, embracing enjoyment in life, drive for self-actualization); persisting through prolonged recovery (yielding to aging, accepting functional limitations, pushing the limit, enduring treatment responsibilities); imposing sicknesses (combatting devastating comorbidities, painful restrictions, emerging disillusionment, anxieties about accumulating side effects, consuming treatment burden); prioritizing graft survival (privileged with a miracle, negotiating risks for longevity, enacting a moral duty, preserving the last opportunity); confronting health deterioration (vulnerability and helplessness, narrowing focus to immediate concerns, uncertainty of survival); and value of existence (purpose through autonomy, refusing the burden of futile treatment, staying alive by all means). Older kidney transplant recipients felt able to enjoy life and strived to live at their newly re-established potential and capability, which motivated them to protect their graft. However, some felt constrained by slow recuperation and overwhelmed by unexpected comorbidities, medication-related side effects, and health decline. Our findings suggest the need to prepare and support older recipients for self

In a retrospective study chest radiographs of 87 bone marrow transplant recipients were analysed. 36 patients had pulmonary complications with lung opacifications. Interstitial changes were more frequent than air-space pneumonias. The latter were caused by bacteria and fungi only. The most common cause of pulmonary complications was cytomegalovirus pneumonia. It was characterised uniformly by a bilateral diffuse interstitial pattern. Idiopathic interstitial pneumonias were indistinguishable from CMV infection. Pneumonias caused by Epstein-Barr virus and protozoa, diffuse radiation pneumonitis and leukaemic infiltrates were rare and also associated with interstitial changes.

Selective digestive decontamination is commonly used to decrease lumenal bacterial flora. Preoperative bowel decontamination may be associated with a lower wound infection rate but has not been shown to decrease risk of intra-abdominal abscess or lower leak rate for enteric anastomoses. Alternatively, the decontamination disrupts the normal flora of the gastrointestinal tract and may affect normal physiology, including immunologic function. This study reports complication rates of an intestine transplant program that has never used bowel decontamination. All adult patients who underwent intestine transplant from 2003 to 2015 at a single center were reviewed. Posttransplant complications included intra-abdominal abscess, enteric fistula, and leak from the enteric anastomosis. Viral, fungal, and bacterial infections in the first year after transplant are reported. There were 184 adult patients who underwent deceased donor intestine transplant during the study period. Among these patients, 30% developed an infected postoperative fluid collection, 4 developed an enteric fistula (2%), and 16 had an enteric or anastomotic leak (8%). The rate of any bacterial infection was 91% in the first year, with a wound infection rate of 25%. Fungal infection occurred in 47% of patients. Rejection rates were 55% at 1 y for isolated intestine patients and 17% for multivisceral (liver inclusive) patients. Among this population of intestine transplant patients in which no bowel decontamination was used, rates of surgical complications, infections, and rejection were similar to those reported by other centers. Bowel decontamination provides no identifiable benefit in intestine transplantation. Copyright © 2018 Elsevier Inc. All rights reserved.

Clostridium difficile infection (CDI) is a major healthcare-associated infection that causes significant morbidity and an economic impact in the United States. In this review, we provide an overview of Clostridium difficile infection in solid organ transplant recipients with an emphasis on recent literature. C. difficile in solid organ transplant population has unique risk factors. Fecal microbiota transplantation has shown favorable results in treatment of recurrent C. difficile in this population. Preliminary data from animal studies suggests excellent efficacy with immunization against C. difficile toxins. Over the last decade, number of individuals receiving solid organ transplants has increased exponentially making peri-transplant complications a common occurrence.C. difficile is a frequent cause of morbidity in solid organ transplant recipients. Early and accurate diagnosis of C. difficile requires a stepwise approach. Differentiating between asymptomatic carriage and infection is a diagnostic challenge. Microbial diversity is inversely proportional to risk of C. difficile infection. Antimicrobial stewardship programs help to retain microbial diversity in individuals susceptible to CDI. Recurrent or relapsing C. difficile infection require fecal microbiota transplantation for definitive cure.

Critical illness polyneuropathy and myopathy are multifaceted complications that follow severe illnesses involving the sensorimotor axons and proximal skeletal muscles. These syndromes have rarely been reported among renal transplant recipients. In this paper, we report a case of acute quadriplegia caused by necrotizing myopathy in a renal transplant recipient with severe pneumonia. The muscle strength in the patient's extremities improved gradually after four weeks of comprehensive treatment, and his daily life activities were normal a year after being discharged.

Antithymocyte globulin rabbit (r-ATG) has been used for the treatment and prevention of acute rejection in renal transplant recipients (RTR). Current manufacturer recommendations for r-ATG dictate the need for administration through a high-flow vein (central line). Previous studies have shown peripheral administration of r-ATG to be safe; however, these studies suggest the co-administration of heparin and hydrocortisone and did not compare the infusion-site reaction rates to a control group. A retrospective analysis was conducted of adult RTR receiving r-ATG or basiliximab between January 2004 and October 2006. Each agent was administered through a dedicated peripheral line. The primary endpoint was the incidence of infusion-site reactions. Other endpoints included the need to replace the intravenous catheter and the incidence of systemic thrombosis within 1 month of transplantation. During the study period, 152 peripheral infusions of r-ATG and 92 peripheral infusions of basiliximab were administered. No difference in infusion-site reactions was noted between the groups. There was also no difference either in the need for peripheral line replacement or the rates of systemic thrombosis. Peripheral administration of r-ATG is safe and can be infused without concomitant heparin and hydrocortisone. This method of r-ATG infusion was shown to be as safe as peripherally administered basiliximab.

Full Text Available Urinary tract infection (UTI is the most common complication following kidney transplantation (KT, which could result in losing the graft. This study aims to identify the prevalence of bacterial UTI among KT recipients in Yemen and to determine the predisposing factors associated with post renal transplantation UTI. A cross sectional study included of 150 patients, who underwent KT was conducted between June 2010 and January 2011. A Morning mid-stream urine specimen was collected for culture and antibiotic susceptibility test from each recipient. Bacterial UTI was found in 50 patients (33.3%. The prevalence among females 40.3% was higher than males 29%. The UTI was higher in the age group between 41-50 years with a percentage of 28% and this result was statistically significant. Predisposing factors as diabetes mellitus, vesicoureteral reflux, neurogenic bladder and polycystic kidney showed significant association. High relative risks were found for polycystic kidney = 13.5 and neurogenic bladder = 13.5. The most prevalent bacteria to cause UTI was Escherichia coli represent 44%, followed by Staphylococcus saprophyticus 34%. Amikacin was the most effective antibiotic against gram-negative isolates while Ciprofloxacin was the most effective antibiotic against Staphylococcus saprophyticus. In conclusion, there is high prevalence of bacterial UTI among KT recipients in Yemen. Diabetes mellitus, vesicoureteral reflux, neurogenic bladder, polycystic kidney and calculi were the main predisposing factors.

Urinary tract infections (UTI) are the most common bacterial infections after renal transplantation and are associated with significant morbidity and mortality. Recurrent or relapsing infections are not uncommon in the early post-transplant period and superadded fungal UTI can occur in these patients, posing a difficult therapeutic problem. Literature on recurrent UTI after transplant as well as the ideal approach to such patients is scanty. We present the case of a renal allograft recipient who presented with relapsing bacterial UTI complicated by systemic fungemia; also, a brief review of fungal UTI is attempted. (author)

Solid organ transplant (SOT) recipients are at greater risk than the general population for complications and mortality from influenza infection. We have conducted a systematic review to assess the management and prevention of influenza infection in SOT recipients. Recommendations are provided about the procurement of organs from donors with influenza infection. We highlight the importance of the possibility of influenza infection in any SOT recipient presenting upper or lower respiratory symptoms, including pneumonia. The importance of early antiviral treatment of SOT recipients with suspected or confirmed influenza infection and the necessity of annual influenza vaccination are emphasized. The microbiological techniques for diagnosis of influenza infection are reviewed. Guidelines for the use of antiviral prophylaxis are provided. Recommendations for household contacts of SOT recipients with influenza infection and health care workers are also included. Antiviral dose adjustment guidelines are presented for cases of impaired renal function and for pediatric populations. Copyright © 2013 Elsevier España, S.L. All rights reserved.

2012-01-01

Full Text Available Background. Tube thoracostomy is widely used throughout the medical, surgical, and critical care specialities. It is generally used to drain pleural collections either as elective or emergency. Complications resulting from tube thoracostomy can occasionally be life threatening. Aim. To present an update on the complications and management of complications of tube thoracostomy. Methods. A review of the publications obtained from Medline search, medical libraries, and Google on tube thoracostomy and its complications was done. Results. Tube thoracostomy is a common surgical procedure which can be performed by either the blunt dissection technique or the trocar technique. Complication rates are increased by the trocar technique. These complications have been broadly classified as either technical or infective. Technical causes include tube malposition, blocked drain, chest drain dislodgement, reexpansion pulmonary edema, subcutaneous emphysema, nerve injuries, cardiac and vascular injuries, oesophageal injuries, residual/postextubation pneumothorax, fistulae, tumor recurrence at insertion site, herniation through the site of thoracostomy, chylothorax, and cardiac dysrhythmias. Infective complications include empyema and surgical site infection. Conclusion. Tube thoracostomy, though commonly performed is not without risk. Blunt dissection technique has lower risk of complications and is hence recommended.

Full Text Available South Asian renal transplant recipients have a higher incidence of cardiovascular disease compared with Caucasian renal transplant recipients. We carried out a study to determine whether paraoxonase 1, a novel biomarker for cardiovascular risk, was decreased in South Asian compared with Caucasian renal transplant recipients. Subjects were matched two to one on the basis of age and sex for a total of 129 subjects. Paraoxonase 1 was measured by mass, arylesterase activity, and two-substrate phenotype assay. Comparisons were made by using a matched design. The frequency of PON1 QQ, QR and RR phenotype was 56%, 37%, and 7% for Caucasian subjects versus 35%, 44%, and 21% for South Asian subjects (χ2=7.72, P=0.02. PON1 mass and arylesterase activity were not significantly different between South Asian and Caucasian subjects. PON1 mass was significantly associated with PON1 phenotype (P=0.0001, HDL cholesterol (P=0.009, LDL cholesterol (P=0.02, and diabetes status (P<0.05. Arylesterase activity was only associated with HDL cholesterol (P=0.003. Thus the frequency of the PON1 RR phenotype was higher and that of the QQ phenotype was lower in South Asian versus Caucasian renal transplant recipients. However, ethnicity was not a significant factor as a determinant of PON1 mass or arylesterase activity, with or without analysis including PON1 phenotype. The two-substrate method for determining PON1 phenotype may be of value for future studies of cardiovascular complications in renal transplant recipients.

Pregnancies in patients with solid organ transplants have higher rates of complications and caesarean sections (CS). To perform an audit of the pregnancy outcomes in transplant recipients, to determine the rate of CS in our cohort, the appropriate skin incision for CS in these patients and to formulate recommendations for preoperative planning. This is a retrospective cohort study. All patients who had a solid organ transplant were identified from the obstetrics database. The operation records of the transplant recipients who delivered by CS were reviewed and the de-identified data were evaluated for pregnancy outcomes. This cohort consisted of 22 women: six had simultaneous pancreas and kidney (SPK) transplants and 16 had kidney transplants. Over a ten-year period, four women had two pregnancies and one had a twin pregnancy, thus 27 babies were born. The rate of CS was 58% (n = 15) and the surgical approach in 13 of these patients was by Pfannenstiel incision. One patient had an elective midline incision at the first CS, which was repeated in the next pregnancy. Two CS were complicated by bladder injury, both occurring in SPK recipients. Patients with solid organ transplants have a higher rate of CS and SPK patients may be at a higher risk of bladder injuries during CS. Our data suggest that Pfannenstiel skin incision is still suitable for these patients. We recommend reviewing the operative details of the transplant operation and a pelvic magnetic resonance imaging for pre-operative planning. © 2018 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Objective: To assess magnitude of tuberculosis (TB) in patients suffering from various haematological malignancies and stem cell transplant (SCT) recipients. Patients and Methods: Patients suffering from various haematological malignancies treated between July 2001 and December 2002 were included in the study. The hospital records and out-patient follow-up charts were reviewed for demographic information, diagnosis, clinical presentation, laboratory investigations, radiological and pathological examinations, sites involved in TB, methods of diagnosis, number and type of anti-tuberculosis drugs given and response to treatment. Results: During the study period a total of 213 (including 25 allogeneic stem cell transplant (SCT) recipients) patients with different haematological disorders were treated. Out of these, 34, including 4 SCT recipients developed tuberculosis. Overall frequency of TB was 16 %. Median age of TB patients was 33.5 years (range 8-80 years). Median time between diagnosis of haematological disorders and tuberculosis was 21 weeks. Sites of involvement by TB were lung (18), disseminated (6), lymph node (5), pleura (2), spine (2) and pericardium (1). Three of the patients died of TB; one undiagnosed, second with multi-drug resistant TB and the third soon after the start of anti-tuberculosis treatment while remaining 31 cases responded to anti-tuberculosis treatment. Conclusion: Tuberculosis is a major problem in immunocompromised patients and there is need to establish guidelines for TB chemoprophylaxis in our setup. (author)

Gabardi, Steven; Kubiak, David W; Chandraker, Anil K; Tullius, Stefan G

2007-12-01

This manuscript will review the risk factors, prevalence, clinical presentation, and management of invasive fungal infections (IFIs) in solid organ transplant (SOT) recipients. Primary literature was obtained via MEDLINE (1966-April 2007) and EMBASE. Abstracts were obtained from scientific meetings or pharmaceutical manufacturers and included in the analysis. All studies and abstracts evaluating IFIs and/or antifungal therapies, with a primary focus on solid organ transplantation, were considered for inclusion. English-language literature was selected for inclusion, but was limited to those consisting of human subjects. Infectious complications following SOT are common. IFIs are associated with high morbidity and mortality rates in this patient population. Determining the best course of therapy is difficult due to the limited availability of data in SOT recipients. Well-designed clinical studies are infrequent and much of the available information is often based on case-reports or retrospective analyses. Transplant practitioners must remain aware of their therapeutic options and the advantages and disadvantages associated with the available treatment alternatives.

Kidney transplantation offers improved survival and quality of life to an increasing number of elderly patients with end-stage kidney disease. However, elderly kidney transplant recipients may face unique challenges due to a higher burden of comorbidity, greater cumulative risk of immunosuppression-related complications and increasing frailty. We aimed to describe the perspectives of elderly kidney transplant recipients. Electronic databases were searched to April 2015. Qualitative studies were eligible if they reported views from elderly kidney transplant recipients (≥60 years). Thematic synthesis was used to analyse the findings. Twenty-one studies involving >116 recipients were included. We identified seven themes. 'Regaining strength and vitality' meant valuing the physical and psychosocial improvements in daily functioning and life participation. 'Extending life' was the willingness to accept any organ, including extended criteria kidneys, to prolong survival. 'Debt of gratitude' entailed conscious appreciation toward their donor while knowing they were unable to repay their sacrifice. 'Moral responsibility to maintain health' motivated adherence to medication and lifestyle recommendations out of an ethical duty to protect their gift for graft survival. 'Unabating and worsening forgetfulness' hindered self-management. 'Disillusionment with side effects and complications' reflected disappointment and exasperation with the unintended consequences of medications. 'Finality of treatment option' was an acute awareness that the current transplant may be their last. Kidney transplantation was perceived to slow and even reverse the experience of aging among elderly recipients, especially compared with dialysis. However, some were frustrated over persistent limitations after transplant, struggled with the burden of medication side effects and worried about a possible return to dialysis if the transplant failed.

Physical rehabilitation of lung transplant candidates and recipients plays an important in optimizing physical function prior to transplant and facilitating recovery of function post-transplant. As medical and surgical interventions in lung transplantation have evolved over time, there has been a demographic shift of individuals undergoing lung transplantation including older individuals, those with multiple co-morbidites, and candidates with respiratory failure requiring bridging to transplantation. These changes have an impact on the rehabilitation needs of lung transplant candidates and recipients. This review provides a practical approach to rehabilitation based on research and clinical practice at our transplant centre. It focuses on functional assessment and exercise prescription during an uncomplicated and complicated clinical course in the pre-transplant, early and late post-transplant periods. The target audience includes clinicians involved in pre- and post-transplant patient care and rehabilitation researchers. PMID:27683630

End-stage renal disease develops in a high percentage of patients with vasculitis, in whom kidney transplant has become a therapeutic option. However, limited data are available on the prognosis and outcomes after kidney transplant in these patients. We aimed to compare the long-term graft survival and graft function in 8 renal transplant recipients with vasculitis (granulomatosis with polyangiitis, microscopic polyangiitis, Goodpasture syndrome, and Henoch-Schonlein purpura) with the other kidney recipients at a single center. We conducted a retrospective study of patients followed for chronic renal failure associated with vasculitis before renal transplant. We excluded patients with no biopsy-proven nephropathy. There was no difference in the occurrence of metabolic and cardiovascular complications in our case group compared with the other graft recipients. Infections were frequent and included cytomegalovirus and urinary tract infection. The rates of bacterial and viral infection were equivalent in our population. The incidence of allograft loss was estimated at 1.8%, less than that seen in our entire transplant population. The presence of vasculitis was not significantly related to renal failure (P = .07). Extrarenal relapse occurred in 1 patient with microscopic polyangiitis. Antineutrophil cytoplasmic antibody levels in patients with granulomatosis with polyangiitis and microscopic polyangiitis did not seem to influence the renal outcome (P = .08). Circulating antineutrophil cytoplasmic antibodies were associated with the development of vascular lesions in the graft but were not significantly correlated with graft survival (P = .07). This study supports the theory that renal transplant is an effective treatment option for patients with end-stage renal disease secondary to vasculitis. These patients fare similarly to, if not better than, other patients.

A clear appreciation of benefits and risks associated with living donor hepatectomy is important to facilitate counselling for the donor, family, and recipient in preparation for living donor liver transplant (LDLT). We report a life-threatening complication occurring in one of our live liver donors at 12 weeks following hemi-liver donation. We experienced five donor complications among our first 50 LDLT: Clavien Grade 1, n=1; Clavien grade 2, n=3; and Clavien grade 3B, n=1. The one with Clavien grade 3B had a life-threatening diaphragmatic hernia occurring 12 weeks following hepatectomy. This was promptly recognized and emergency surgery was performed. The donor is well at 1-year follow-up. Here we provide a review of reported instances of diaphragmatic hernia following donor hepatectomy with an attempt to elucidate the pathophysiology behind such occurrence. Life-threatening donor risk needs to be balanced with recipient benefit and risk on a tripartite basis during the counselling process for LDLT. With increasing use of LDLT, we need to be aware of such life-threatening complication. Preventive measures in this regard and counselling for such complication should be incorporated into routine work-up for potential live liver donor.

Since lung transplant recipients are susceptible to infections and inhaled pollution, many centers warn against pets. However, data supporting this recommendation are lacking. Our program is less restrictive regarding pets. This study, for the first time, investigates the association of pets with physiological and psychological parameters in these patients. A questionnaire concerning pets was sent to 104 lung transplant recipients. Lung function tests, levels of exhaled nitric oxide (FE(NO)), need for antibiotic treatments and hospitalizations, creatinine clearance, body mass index (BMI) and demographic data were assessed. Additionally, the questionnaire of life satisfaction (FLZ), a question on summarized life satisfaction (LS), the life orientation test (LOT), the hospital anxiety depression scale (HADS) and the social support questionnaire (F-SozU) were assessed. Response rate was 86%. Fifty-two percent defined themselves as pet owners, whereas 48% did not. The two groups did not differ in demographic or physiological data. Significant differences in FLZ (79/65, p = 0.04), in LS (4.3/3.9, p = 0.01), LOT (32/29, p = 0.006) and F-SozU (4.5/4.2, p = 0.04) were found in favor of pet owners. In lung transplant recipients keeping pets the frequency of somatic complications is not higher compared to lung transplant recipients without pets. After lung transplantation, pets are associated with a better quality of life.

Reproductive health in Irish female renal transplant recipients.

OBJECTIVE: To report the pregnancy outcomes in Irish female renal transplant recipients on modern maintenance immunosuppression. METHODS: The Republic of Ireland transplant database was accessed to identify the patient cohort in question. All female renal transplant recipients whose transplantation was in Ireland before or during their reproductive years were included. A questionnaire was sent to the identified women. A chart review was performed for those women who reported a pregnancy following renal transplantation. RESULTS: Two hundred and ten women met the inclusion criteria. There was a response rate of 70% (n = 148). Eighteen women reported 29 pregnancies. The live birth rate was 76%. The mean gestation of the live births was 36.2 weeks with a mean birth weight of 3.0 kg. There were six cases of pre-eclampsia. Twin pregnancies and those entering pregnancy with a creatinine greater than 135 micromol\\/l had particularly complicated clinical courses. Four women had not conceived post transplant despite actively trying for over 1 year. Two women utilised assisted fertility methods (in vitro fertilisation), one of whom became pregnant. CONCLUSIONS: A significant proportion of women who attempt to conceive following renal transplantation are successful, without the use of assisted fertility. Pregnancy in this setting warrants meticulous multidisciplinary care.

Full Text Available Abstract Background Surgery after (chemoradiation (RCTX/RTX is felt to be plagued with a high incidence of wound healing complications reported to be as high as 70%. The additional use of vascularized flaps may help to decrease this high rate of complications. Therefore, we examined within a retrospective single-institutional study the peri--and postoperative complications in patients who underwent surgery for salvage, palliation or functional rehabilitation after (chemoradiation with regional and free flaps. As a second study end point the Karnofsky performance status (KPS was determined preoperatively and 3 months postoperatively to assess the impact of such extensive procedures on the overall performance status of this heavily pretreated patient population. Findings 21 patients were treated between 2005 and 2010 in a single institution (17 male, 4 female for salvage (10/21, palliation (4/21, or functional rehabilitation (7/21. Overall 23 flaps were performed of which 8 were free flaps. Major recipient site complications were observed in only 4 pts. (19% (1 postoperative haemorrhage, 1 partial flap loss, 2 fistulas and major donor site complications in 1 pt (wound dehiscence. Also 2 minor donor site complications were observed. The overall complication rate was 33%. There was no free flap loss. Assessment of pre- and postoperative KPS revealed improvement in 13 out of 21 patients (62%. A decline of KPS was noted in only one patient. Conclusions We conclude that within this (chemoradiated patient population surgical interventions for salvage, palliation or improve function can be safely performed once vascularised grafts are used.

2017-03-01

Full Text Available Infectious vascular complications affecting transplant recipients may lead to severe morbidity and graft loss. This is a retrospective review of vascular repair with bovine pericardial patch (BPP in infected fields for immunosuppressed patients. BPP was used as either a patch or an interposition graft. Five cases of arterial reconstruction in infected fields using BPP were performed. There were no complications related to bleeding, thrombosis, or recurrent infection. In our limited experience, the use of BPP as a vascular patch is successful, and it represents an alternative when vascular reconstruction is needed in the context of infected fields.

In eight recipients of allogeneic bone marrow grafts who had sex-mismatched donors, the reduction and subsequent repopulation of T4+ and T8+ T-lymphocytes of recipient origin were studied. The origin of the donor-recipient T4+ and T8+ T cells was studied using quinacrine staining of Y chromatin combined with T-cell typing for T4 and T8. Following chemoradiotherapy and bone marrow transplantation (BMT), T cells reached their nadir at a median of five (range 1-8) days after BMT. T8+ T cells decreased at a faster rate from the peripheral blood than T4+ T cells. The first T cells that appeared in the circulation at day 12 were predominantly T4+, and a large number of them were of recipient origin. Thereafter, they gradually decreased, and the numbers of T cells of donor origin increased. In the patients who had no or only minor complications, T4+ and T8+ T cells of donor origin repopulated the blood at similar rates. This pattern, however, was modified by severe graft-versus-host disease or by cytomegalovirus infection

Agrobacterium tumefaciens is a natural genetic engineer widely used to deliver DNA into various recipients, including plant, yeast and fungal cells. The bacterium can transfer single-stranded DNA molecules (T–DNAs) and bacterial virulence proteins, including VirE2. However, neither the DNA nor the protein molecules have ever been directly visualized after the delivery. In this report, we adopted a split-GFP approach: the small GFP fragment (GFP11) was inserted into VirE2 at a permissive site to create the VirE2-GFP11 fusion, which was expressed in A. tumefaciens; and the large fragment (GFP1–10) was expressed in recipient cells. Upon delivery of VirE2-GFP11 into the recipient cells, GFP fluorescence signals were visualized. VirE2-GFP11 was functional like VirE2; the GFP fusion movement could indicate the trafficking of Agrobacterium-delivered VirE2. As the natural host, all plant cells seen under a microscope received the VirE2 protein in a leaf-infiltration assay; most of VirE2 moved at a speed of 1.3–3.1 μm sec−1 in a nearly linear direction, suggesting an active trafficking process. Inside plant cells, VirE2-GFP formed filamentous structures of different lengths, even in the absence of T-DNA. As a non-natural host recipient, 51% of yeast cells received VirE2, which did not move inside yeast. All plant cells seen under a microscope transiently expressed the Agrobacterium-delivered transgene, but only 0.2% yeast cells expressed the transgene. This indicates that Agrobacterium is a more efficient vector for protein delivery than T-DNA transformation for a non-natural host recipient: VirE2 trafficking is a limiting factor for the genetic transformation of a non-natural host recipient. The split-GFP approach could enable the real-time visualization of VirE2 trafficking inside recipient cells. PMID:24299048

Full Text Available BackgroundThe aim of lower-extremity reconstruction has focused on wound coverage and functional recovery. However, there are limitations in the use of a local flap in cases of extensive defects of the lower-extremities. Therefore, free flap is a useful option in lower-extremity reconstruction.MethodsWe performed a retrospective review of 49 patients (52 cases who underwent lower-extremity reconstruction at our institution during a 10-year period. In these patients, we evaluated causes and sites of defects, types of flaps, recipient vessels, types of anastomosis, survival rate, and complications.ResultsThere were 42 men and 10 women with a mean age of 32.7 years (range, 3-72 years. The sites of defects included the dorsum of the foot (19, pretibial area (17, ankle (7, heel (5 and other sites (4. The types of free flap included latissimus dorsi muscle flap (10, scapular fascial flap (6, anterolateral thigh flap (6, and other flaps (30. There were four cases of vascular complications, out of which two flaps survived after intervention. The overall survival of the flaps was 96.2% (50/52. There were 19 cases of other complications at recipient sites such as partial graft loss (8, partial flap necrosis (6 and infection (5. However, these complications were not notable and were resolved with skin grafts.ConclusionsThe free flap is an effective method of lower-extremity reconstruction. Good outcomes can be achieved with complete debridement and the selection of appropriate recipient vessels and flaps according to the recipient site.

Neurological complications after lung transplantation are common. The full spectrum of neurological complications and their impact on clinical outcomes has not been extensively studied. We investigated the neurological incidence of complications, categorized according to whether they affected the central, peripheral or autonomic nervous systems, in a series of 109 patients undergoing lung transplantation at our center between January 1 2013 and December 31 2014. Fifty-one patients (46.8%) presented at least one neurological complication. Critical illness polyneuropathy-myopathy (31 cases) and phrenic nerve injury (26 cases) were the two most prevalent complications. These two neuromuscular complications lengthened hospital stays by a median period of 35.5 and 32.5 days respectively. However, neurological complications did not affect patients' survival. The real incidence of neurological complications among lung transplant recipients is probably underestimated. They usually appear in the first two months after surgery. Despite not affecting mortality, they do affect the mean length of hospital stay, and especially the time spent in the Intensive Care Unit. We found no risk factor for neurological complications except for long operating times, ischemic time and need for transfusion. It is necessary to develop programs for the prevention and early recognition of these complications, and the prevention of their precipitant and risk factors.

Solid organ and hematopoietic stem cell transplant recipients are uniquely predisposed to develop clinical illness, often with increased severity, due to a variety of common and opportunistic viruses. Patients may acquire viral infections from the donor (donor-derived infections), from reactivation of endogenous latent virus, or from the community. Herpes viruses, most notably cytomegalovirus and Epstein Barr virus, are the most common among opportunistic viral pathogens that cause infection after solid organ and hematopoietic stem cell transplantation. The polyoma BK virus causes opportunistic clinical syndromes predominantly in kidney and allogeneic hematopoietic stem cell transplant recipients. The agents of viral hepatitis B and C present unique challenges particularly among liver transplant recipients. Respiratory viral illnesses due to influenza, respiratory syncytial virus, and parainfluenza virus may affect all types of transplant recipients, although severe clinical disease is observed more commonly among lung and allogeneic hematopoietic stem cell transplant recipients. Less common viral infections affecting transplant recipients include those caused by adenoviruses, parvovirus B19, and West Nile virus. Treatment for viruses with proven effective antiviral drug therapies should be complemented by reduction in the degree of immunosuppression. For others with no proven antiviral drugs for therapy, reduction in the degree of immunosuppression remains as the sole effective strategy for management. Prevention of viral infections is therefore of utmost importance, and this may be accomplished through vaccination, antiviral strategies, and aggressive infection control measures.

Nipple-sparing mastectomy (NSM) is gaining popularity due to its superior aesthetic results. When reconstructing the breast with free abdominal tissue transfer, we must readdress the recipient vessel, because NSM can cause difficulty in access to the chest vessel. Between June 2006 and March 2011, a total of 92 women underwent NSM with free abdominal tissue transfer. A lateral oblique incision was used for the nipple-sparing mastectomy. For recipient vessels, the internal mammary vessels were chosen if the mastectomy flap did not block access to the vessels. If it did, the thoracodorsal vessels were used. Age, degree of breast ptosis, weight of the mastectomy specimen, and related complications of the internal mammary vessel group and the thoracodorsal vessel group were compared. Thoracodorsal vessels were used as recipient vessels in 59 cases, and internal mammary vessels in 33 cases including 4 cases with perforators of the internal mammary vessels. Breast reconstruction was successful in all cases except one case involving a total flap failure, which was replaced by a silicone gel implant. The internal mammary group and the thoracodorsal group were similar in terms of age, height, breast weight, and degree of ptosis. The flap related complications such as flap loss and take-back operation rates were not significantly different between the two groups. The rate of nipple necrosis was higher in the internal mammary group. The thoracodorsal vessels could produce comparable outcomes in breast reconstruction after nipple-sparing mastectomies. If access to internal mammary vessels is difficult, the thoracodorsal vessel can be a better choice.

Full Text Available We retrospectively reviewed the records of 273 renal transplant recipients who received allograft transplants between 1994 and 2004 and recorded the incidence and types of de novo malignancies that developed in these patients. The study was carried out at the Al-karama and Al-rasheed kidney transplant centers in Baghdad, Iraq. A total of 16 patients developed malignancies. The tumors included Kaposi′s sarcoma (KS in eight patients, squamous cell carcinoma (SCC in four, basal cell carcinoma (BCC in two and both renal cell carcinoma of the allograft and brain tumor in one patient. Thus, KS was the most common malignancy encountered in our series, with a prevalence of 2.9%, followed by SCC observed in 1.5% and BCC found in 0.7 % of the patients. The average latency period between transplantation and development of malignancy was 6.5 months for KS, 3.0 months for SCC and 8.5 months for BCC. To our knowledge, this is the first long-term follow-up study for malignant complications identified in kidney recipients in Iraq.

A 22-year-old woman with cystic fibrosis (CF) developed lung abscess, as a rare complication caused by multidrug-resistant (MDR) Acinetobacter baumannii infection, after lung transplantation (LT). After 6 months of long-term antibiotic therapy, the abscess was successfully eliminated. In reviewed published literature, no previous report was found describing this kind of complication caused by MDR A. baumannii in post-LT patient with CF. In our experience, lung abscess in LT recipients with CF can be successfully treated with prolonged antibiotic therapy.

To explore the intersection of peer-to-peer milk sharing and donor milk banks. A descriptive survey design containing closed and open-ended questions was used to examine women's perceptions of peer-to-peer milk sharing and milk banking. Closed-ended questions were analyzed using descriptive statistics and conventional qualitative content analysis was used to analyze open-ended responses. Participants were recruited via the Facebook sites of two online milk-sharing networks (Human Milk 4 Human Babies and Eats on Feet). Ninety-eight milk donors and 41 milk recipients who had donated or received breast milk in an arrangement that was facilitated via the Internet. One half of donor recipients could not donate to a milk bank because there were no banks local to them or they did not qualify as donors. Other respondents did not donate to a milk bank because they viewed the process as difficult, had philosophical objections to milk banking, or had a philosophical attraction to peer sharing. Most donor respondents felt it was important to know the circumstances of their milk recipients. No recipient respondents had obtained milk from a milk bank; it was recognized that they would not qualify for banked milk or that banked milk was cost prohibitive. Peer-to-peer milk donors and recipients may differ from milk bank donors and recipients in significant ways. Cooperation between milk banks and peer sharing networks could benefit both groups. © 2013 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

Cystic duct remnant mucocele is an extremely rare complication of liver transplantation in children. Surgical correction is usually required for cystic duct remnant mucocele when it causes biliary obstruction. We describe a 14-month-old liver transplant recipient who presented with biliary obstruction 1 month after orthotopic liver transplantation with an end-to-end choledochocholedocal biliary anastomosis for hepatoblastoma. US, CT and cholangiography findings were consistent with mucocele of the allograft cystic duct remnant. Surgery was not needed in our patient because the mucocele and biliary obstruction had resolved on repeat imaging most likely due to guidewire manipulation during cholangiography, resulting in opening of the cystic duct remnant orifice and drainage into the common duct.

2016-12-03

Pediatric supracondylar humerus fractures are the most common elbow fractures in pediatric patients. Surgical fixation using pins is the primary treatment for displaced fractures. Pin site infections may follow supracondylar humerus fracture fixation; the previously reported incidence rate in the literature is 2.34%, but there is significant variability in reported incidence rates of pin site infection. This study aims to define the incidence rate and determine pre-, peri-, and postoperative factors that may contribute to pin site infection following operative reduction, pinning, and casting. A retrospective chart analysis was performed over a one-year period on patients that developed pin site infection. A cast care form was added to Nemours' electronic medical records (EMR) system (Epic Systems Corp., Verona, WI) to identify pin site infections for retrospective review. The cast care form noted any inflamed or infected pins. Patients with inflamed or infected pin sites underwent a detailed chart review. Preoperative antibiotic use, number and size of pins used, method of postoperative immobilization, pin dressings, whether postoperative immobilization was changed prior to pin removal, and length of time pins were in place was recorded. A total of 369 patients underwent operative reduction, pinning, and casting. Three patients developed a pin site infection. The pin site infection incidence rate was 3/369=0.81%. Descriptive statistics were reported for the three patients that developed pin site infections and three patients that developed pin site complications. Pin site infection development is low. Factors that may contribute to the development of pin site infection include preoperative antibiotic use, length of time pins are left in, and changing the cast prior to pin removal.

Deep brain stimulation of the subthalamic nucleus is an important treatment option for advanced stages of idiopathic Parkinson's disease, leading to significant improvement of motor symptoms in suited patients. Hardware-related complications such as technical malfunction, skin erosion, and infections however cause patient discomfort and additional expense. The patient presented here suffered a putrid infection of the impulse generator site following only local dental treatment of apical parodontitis. Therefore, prophylactic systemic antibiotic treatment is recommended for patients with implanted deep brain stimulation devices in case of operations, dental procedures, or infectious disease.

2015-08-01

Full Text Available Sickle Cell Anaemia (SCA is the most common inherited blood disorder and is associated with severe morbidity and decreased survival. Allogeneic Haematopoietic Stem Cell Transplantation (HSCT is the only curative approach. Nevertheless the decision to perform a marrow transplant includes the risk of major complications  and mortality transplant related. The infections represent the main cause of mortality for SCA patients undergoing transplant. Invasive Pulmonary Aspergillosis (IPA is a devastating opportunistic infection and remains a significant cause of morbidity and mortality in HSCT recipients. Data regarding IPA in the setting of SCA are lacking. In the present report,  we describe a patient with SCA who developed IPA after allogeneic bone marrow transplant. The fungal infection was treated by systemic antifungal therapy in addition to the surgery, despite  mild chronic GVHD and with continuing immunosuppression therapy. This case shows that IPA occurring in bone marrow recipient with SCA can be successful treated

Mesenchymal stromal cells (MSCs) are multipotent cells, which exhibit broad immunosuppressive activities. Moreover, they may be administered irrespectively of human leukocyte antigen (HLA) compatibility, without inducing life-threatening immunological reactions, as they express no HLA class II and limited HLA class I antigens under resting conditions. These characteristics have made MSC an appealing candidate for cell therapy after hematopoietic stem cell transplantation (HSCT), for example, for treatment of graft-versus-host disease (GvHD) or for graft rejection prevention/treatment in allogeneic HSCT recipients. Unfortunately, information regarding the effect of MSC infusion on the host response to infectious agents is scarce, and study results on infectious complications in patients receiving MSC are conflicting. The present review focuses on the available data from in vitro studies and animal models regarding the interaction of MSC with bacterial, viral and fungal pathogens. In a clinical part, we present the current information on infectious complications in allogeneic HSCT recipients who had received MSCs as prophylaxis or treatment of GvHD disease.

2015-01-01

Full Text Available Fournier′s gangrene is not a common cause of morbidity in renal transplant recipients, but, if it occurs, it is difficult to treat because of the immunosuppression and associated increased mortality rate. We describe the case of a male patient who underwent renal transplantation with complicated post-operative course, resulting in cecum perforation (thermal injury due to cautery use during transplantation requiring exploratory laparotomy and cecostomy. A few days later, he developed Fournier′s gangrene and urgent radical surgical debridement of the scrotum was performed, along with aggressive antibiotic regimen and the immunosuppressive treatment was modified. Subsequently, the patient underwent scheduled cecostomy closure (right hemicolectomy, while the scrotum trauma healed with tertiary intention. Epidemiologic characteristics, clinical presentation, diagnostic workup, therapeutic options and morbidity-mortality rates of Fournier′s gangrene are reviewed, emphasizing the role of immunosuppression in renal transplant recipients to disease development.

Serial Assessment of Immune Status by Circulating CD8+ Effector T Cell Frequencies for Posttransplant Infectious Complications

Shinji Uemoto

2008-01-01

Full Text Available To clarify the role of CD8+ effector T cells for infectious complications, 92 recipients were classified according to the hierarchical clustering of preoperative CD8+CD45 isoforms: Group I was naive, Group II was effector memory, and Group III was effector (E T cell-dominant. The posttransplant infection rates progressively increased from 29% in Group I to 64.3% in Group III recipients. The posttransplant immune status was compared with the pretransplant status, based on the measure (% difference and its graphical form (scatter plot. In Groups I and II, both approaches showed a strong upward deviation from pretransplant status upon posttransplant infection, indicating an enhanced clearance of pathogens. In Group III, in contrast, both approaches showed a clear downward deviation from preoperative status, indicating deficient cytotoxicity. The % E difference and scatter plot can be used as a useful indicator of a posttransplant infectious complication.

Full Text Available Background: Different complications may occur at laparoscopic port sites. The incidence of these varies with the size of the ports and the types of procedure performed through them. Objectives: The aim was to observe the rate and types of complications attending laparoscopic port wounds and to identify risk factors for their occurrence. Patients and Methods: This is a prospective descriptive study of all patients who had laparoscopic operations in one general surgery unit of a University Teaching Hospital in Nigeria between January 2009 and December 2012. Results: A total of 236 (155 female and 81 male patients were included. The laparoscopic procedures include 63 cholecystectomies, 49 appendectomies, 62 diagnostic, biopsy and staging procedures, 22 adhesiolyses, six colonic surgeries, eight hernia repairs and 22 others. Port site complications occurred in 18 (2.8% ports on 16 (6.8% patients including port site infections in 12 (5.1% and hypertrophic scars in 4 (1.7% patients, while one patient each had port site bleeding and port site metastasis. Nine of 11 infections were superficial, while eight involved the umbilical port wound. Conclusion: Port site complications are few following laparoscopic surgeries in our setting. We advocate increased adoption of laparoscopic surgeries in Nigeria to reduce wound complications that commonly follow conventional open surgeries.

Lung Transplantation for Cystic Fibrosis: Results, Indications, Complications, and Controversies

Survival in patients with cystic fibrosis (CF) has improved dramatically over the past 30 to 40 years, with mean survival now approximately 40 years. Nonetheless, progressive respiratory insufficiency remains the major cause of mortality in CF patients, and lung transplantation (LT) is eventually required. Timing of listing for LT is critical, because up to 25 to 41% of CF patients have died while awaiting LT. Globally, approximately 16.4% of lung transplants are performed in adults with CF. Survival rates for LT recipients with CF are superior to other indications, yet LT is associated with substantial morbidity and mortality (~50% at 5-year survival rates). Myriad complications of LT include allograft failure (acute or chronic), opportunistic infections, and complications of chronic immunosuppressive medications (including malignancy). Determining which patients are candidates for LT is difficult, and survival benefit remains uncertain. In this review, we discuss when LT should be considered, criteria for identifying candidates, contraindications to LT, results post-LT, and specific complications that may be associated with LT. Infectious complications that may complicate CF (particularly Burkholderia cepacia spp., opportunistic fungi, and nontuberculous mycobacteria) are discussed. PMID:25826595

We describe a 40-year-old living-donor renal-transplant recipient who underwent successful ureterolithotripsy. He had been on hemodialysis for >15 years pre-transplant and underwent ureteroureterostomy along with the surgery. One year post-transplant, ultrasound examination demonstrated hydronephrosis, and CT showed a 6-mm ureteral calculus at the ureteroureterostomy site. No pain and no elevated serum creatinine were present. As the ureter was easily accessed, we performed a ureterolithotripsy, which would confirm whether a suture caused the calculus. Despite ureteral tortuosity, laser stone fragmentation succeeded. The calculus was completely removed with an antegrade guidewire. Mild postoperative ureteral stenosis resolved with a temporary ureteral stent without balloon dilation. Ureterolithotripsy is effective even in renal transplant recipients with ureteroureterostomy.

2013-08-01

The aim of this study was to objectively assess the reliability of the cone-beam computed tomography (CBCT) as a tool to pre-operatively determine radiographic bone density (RBD) by the density values provided by the system, analyzing its relationship with histomorphometric bone density expressed as bone volumetric fraction (BV/TV) assessed by micro-CT of bone biopsies at the site of insertion of dental implants in the maxillary bones. Thirty-nine bone biopsies of the maxillary bones at the sites of 39 dental implants from 31 edentulous healthy patients were analyzed. The NobelGuide™ software was used for implant planning, which also allowed fabrication of individual stereolithographic surgical guides. The analysis of CBCT images allowed pre-operative determination of mean density values of implant recipient sites along the major axis of the planned implants (axial RBD). Stereolithographic surgical guides were used to guide implant insertion and also to extract cylindrical bone biopsies from the core of the exact implant site. Further analysis of several osseous micro-structural variables including BV/TV was performed by micro-CT of the extracted bone biopsies. Mean axial RBD was 478 ± 212 (range: 144-953). A statistically significant difference (P = 0.02) was observed among density values of the cortical bone of the upper maxilla and mandible.

Heart transplantation (HTx) is the preferred treatment for patients with end-stage heart failure and has been successful for >30 y. The clinical course of recipients at the extreme of age is unknown. We reviewed our experience to determine the overall health and prevalence of Tx-related medical problems for recipients in their ninth decade. We reviewed the UCTP experience from 1985 to present to identify patients who survived into their 80s and matched (1:1) with other recipients for gender and age at HTx, but did not survive to ≥80 y. The end point was the prevalence of medical problems. Since 1985, 1129 adult HTx have been performed and 14 patients (1.2%) survived to ≥80 y old. The mean age at HTx was 63 ± 4 y. Of octogenarians, the majority were males with ischemic cardiomyopathy. The average survival after transplant was 19 ± 5 y in the octogenarians and 5 ± 5 y in the controls (P  55%) for all octogenarians at age 80 y. Despite improvements in posttransplant care, survival of HTx patients into the ninth decade is rare (1%). For those surviving into their 80s, cardiac function is preserved but dyslipidemia, renal insufficiency, and skin cancers are common. As the age of Htx patients continues to increase, posttransplant care should be tailored to minimize post-HTx complications and further extend survival. Copyright © 2017 Elsevier Inc.

Donor cell leukemia (DCL) is a relatively rare but well documented complication of hematopoietic stem cell transplantation. So far, publications described only DCL arising de novo in the recipient. In this study, we describe a case of chronic lymphocytic leukemia (B-CLL) developing in a volunteer unrelated donor from the Czech National Marrow Donors Registry (CNMDR) several years after donation. From archival DNA sample, we have retrospectively found that subclinical CLL clone was already present at the time of donation but early death of recipient prevented eventual development of DCL. This case documents well the long period between detection of B-CLL clone and full development of clinical-laboratory symptomatology. The medical and ethical questions posed by an isolated case of detection of hematological malignancy present either only in the donor or only in the recipient are discussed. The case demonstrates the increasing risk of development of various forms of DCL and thus highlights the need for long-term monitoring of stem cell donor, not only in terms of health of donor but also in terms of potential risks for the recipient.

Correlation of immunosuppression scheme with renal graft complications detected by dynamic renal scintigraphy

Martins, Flavia Paiva Proenca; Gutfilen, Bianca

2001-01-01

Dynamic renal scintigraphy allows the diagnosis of complications in patients submitted to organ transplantation, such as perfusion abnormalities, acute tubular necrosis and rejection. In this study we employed 99m Tc-DTPA scintigraphy to study patients submitted to kidney transplantation. The results obtained and the clinical findings were conjunctively analyzed in order to detect graft rejection or other complications. The type of immunosuppressive scheme used was also correlated with the observed complications. Fifty-five patients submitted to kidney transplantation from 1989 to 1999 were evaluated. All patients with nephrotoxicity received a 3-drug immunosuppressive scheme. In this study, acute rejection was the most frequent complication (40.4%) observed following transplantation. Thirteen of 15 recipients of cadaveric kidney grafts presented acute tubular necrosis. Only one false-positive case was observed when scintigraphy and clinical findings were not concordant. We suggest carrying out renal scintigraphy to follow-up post-transplantation patients. (author)

A review of the imaging and intervention of liver transplant complications.

LENUS (Irish Health Repository)

McEvoy, S

2010-09-01

Liver transplantation has become a successful surgical solution to a variety of medical and oncological parenchymal liver diseases. As a result, these patients are being encountered more frequently within diagnostic imaging departments which may be remote from the transplant centre. Radiologists must therefore be proficient in identifying normal post-transplant anatomy which involves the anastomosis of four structures between the donor and recipient, namely the hepatic artery, the main portal vein, the retro-hepatic inferior vena cava and the extra-hepatic bile ducts. A number of potential complications can arise involving any or all of these structures, which can be potentially devastating and lead to graft failure. Radiologists must familiarise themselves with the normal post-operative appearances of liver transplantation and become competent in diagnosing post-transplant complications. Where possible, complications should be treated using interventional radiological techniques, thus avoiding the need for repeat surgical intervention or retransplantation.

First Case Report of Acute Renal Failure After Mesh-Plug Inguinal Hernia Repair in a Kidney Transplant Recipient.

Acute renal failure due to ureter compression after a mesh-plug inguinal repair in a kidney transplant recipient has not been previously reported to our knowledge. A 62-year-old man, who successfully underwent kidney transplantation from a deceased donor 6 years earlier, was admitted for elective repair of a direct inguinal hernia. The patient underwent an open mesh-plug repair of the inguinal hernia with placement of a plug in the preperitoneal space. We did not observe the transplanted ureter and bladder during dissection of the inguinal canal. Immediately after surgery, the patient became anuric, and a graft sonography demonstrated massive hydronephrosis. The serum creatinine level increased rapidly, and the patient underwent an emergency reoperation 8 hours later. During surgery, we did not identify the ureter but, immediately after plug removal, urine output increased progressively. We completed the hernia repair using the standard technique, without plug interposition, and the postoperative course was uneventful with complete resolution of graft dysfunction 3 days later. Furthermore, we reviewed the clinical features of complications related to inguinal hernia surgery. An increased risk of urological complications was reported recently in patients with a previous prosthetic hernia repair undergoing kidney transplantation, mainly due to the mesh adhesion to surrounding structures, making the extraperitoneal dissection during the transplant surgery very challenging. Moreover, older male kidney transplant recipients undergoing an inguinal hernia repair may be at higher risk of graft dysfunction due to inguinal herniation of a transplanted ureter. Mesh-plug inguinal hernia repair is a safe surgical technique, but this unique case suggests that kidney transplant recipients with inguinal hernia may be at higher risk of serious urological complications. Surgeons must be aware of the graft and ureter position before proceeding with hernia repair. A prompt diagnosis

This study examined the association among caregiver labor force participation, employees' caregiving activities, and the amount and quality of care received by care recipients. Telephone interviews were conducted with 478 adults who were employed full time and 705 nonemployed adults who provided care to a family member or friend aged 50 or older, identified through random sampling of California households. We assessed care recipient impairment and service problems; the amounts and types of assistance received from caregivers, family and friends, and paid providers; and caregiver utilization of support services. Care recipients of caregivers employed full time were less likely to receive large amounts of care from their caregivers, more likely to receive personal care from paid care providers, more likely to use community services, and more likely to experience service problems than were care recipients of nonemployed caregivers. Employed caregivers were more likely to use caregiver support services than were nonemployed caregivers. Accommodation to caregiver full-time employment involves selective supplementation by caregivers and their care recipients, reflecting increased reliance on formal support services as well as increased vulnerability to service problems and unmet care recipient needs. These findings suggest the need for greater attention to the well-being of disabled elders whose caregivers are employed full time.

Conclusions: Renal recipients with BM PTLD represent worse outcome and more unfavorable histopathological phenomenon than in other organ involvements. Moreover, a concomitant PTLD involvement site in liver was found which necessitates full hepatic evaluation for a potential complication by the disease in renal recipients whose BM is involved.

The incidence of biliary complications after living donor adult liver transplantation (LDALT) is still high due to the bile duct variation and necessity reconstruction of multiple small bile ducts. The current surgical management of the biliary variants is unsatisfactory. We evaluated the role of a new surgical approach in a complicated hilar bile duct variant (Nakamura type IV and Nakamura type II) under emergent right lobe LDALT for high model for end-stage liver disease score patients. The common hepatic duct (CHD) and the left hepatic duct (LHD) of the donor were transected in a right-graft including short common trunks with right posterior and anterior bile ducts, whereas the LHD of the donor was anastomosed to the CHD and the common trunks of a right-graft bile duct and the recipient CHD was end-to-end anastomosed. Ten of 13 grafts (Nakamura types II, III, and IV) had two or more biliary orifices after right graft lobectomy; seven patients had biliary complications (53.8%). Later, the surgical innovation was carried out in five donors with variant bile duct (four Nakamura type IV and one type II), and, consequently, no biliary or other complications were observed in donors and recipients during 47-53 months of follow-up; significant differences ( P  ducts in a complicated donor bile duct variant may facilitate biliary reconstruction and reduce long-term biliary complications.

Home enteral nutrition recipients: patient perspectives on training, complications and satisfaction

LENUS (Irish Health Repository)

Boland, Karen

2016-10-01

The equitable provision of home enteral nutrition (HEN) in the community can have a transformative effect on patient experience and family life for adults and children alike. While optimising quality of life in HEN patients can be challenging, the initiation of HEN positively impacts this measure of healthcare provision.1 Quality of life scores have been shown to improve in the weeks after hospital discharge, and HEN is physically well tolerated. However, it may be associated with psychological distress, and sometimes reluctance among HEN patients to leave their homes.2 Globally, HEN can attenuate cumulative projected patient care costs through a reduction in hospital admission and complications including hospital acquired infections.3 In an era where the cost of disease related malnutrition and associated prolonged hospital stay is being tackled in our healthcare systems, the role of HEN is set to expand. This is a treatment which has clear clinical and social benefits, and may restore some independence to patients and their families. Rather than the indications for HEN being focused on specific diagnoses, the provision of months of quality life at home for patients is adequate justification for its prescription.4 Previously, a review of HEN service provision in 39 cases demonstrated that patients want structured follow-up after hospital discharge, and in particular, would like one point of contact for HEN education and discharge.5 Management structures, funding challenges and the need for further education, particularly within the primary care setting may limit optimal use of HEN. The Irish Society for Clinical Nutrition and Metabolism (IrSPEN) aims to develop a national guideline document, drawing on international best practice, forming a template and standards for local policy development in the area of HEN service provision, training and follow-up. The first step in guideline development was to investigate patient experience for adults and children alike. Care

Reconstruction in a vessel-depleted neck is challenging. The success rates can be markedly decreased because of unavailability of suitable recipient vessels. In order to obtain a reliable flow, recipient vessels away from the zone of fibrosis, radiation, or infection need to be explored. The aim of this report is to present our experience and clinical outcomes using the retrograde flow coming from the distal transverse cervical artery (TCA) as a source for arterial inflow for complex head and neck reconstruction in patients with a vessel-depleted neck. Between July 2010 and June 2016, nine patients with a vessel-depleted neck underwent secondary head and neck reconstruction using the retrograde TCA as recipient vessel for microanastomosis. The mean age was 49.6 years (range, 36 to 68 years). All patients had previous bilateral neck dissections and all, except one, had also received radiotherapy. Indications included neck contracture release (n = 3), oral (n = 1), mandibular (n = 3) and pharyngoesophageal (n = 2) reconstruction necessitating free anterolateral thigh (n = 3) and medial sural artery (n = 1) perforator flaps, fibula (n = 3) and ileocolon (n = 2) flaps respectively. There was 100% flap survival rate with no re-exploration or any partial flap loss. One case of intra-operative arterial vasospasm at the anastomotic suture line was managed intra-operatively with vein graft interposition. There were no other complications or donor site morbidity during the follow-up period. In a vessel-depleted neck, the reverse flow of the TCA may be a reliable option for complex secondary head and neck reconstruction in selected patients. © 2017 Wiley Periodicals, Inc.

Prospective, single-site, randomized, Food and Drug Administration-approved investigational device exemption clinical trials of 2 cervical arthroplasty (CA) devices. To evaluate complications with CA occurring more than 4 years after the surgical procedure in Food and Drug Administration clinical trials of the Bryan and Prestige LP arthroplasty devices. Reports of several randomized clinical studies have shown CA to be a safe and effective alternative to anterior cervical fusion in the treatment of degenerative cervical disc disorders. A majority include follow-up intervals of 4 years or less. Between 2002 and 2006, 94 patients were enrolled in Food and Drug Administration studies of the Bryan and Prestige LP cervical disc devices. Charts, imaging studies, and hospital records were reviewed for those who underwent arthroplasty and returned more than 4 years after their surgical procedure with neck-related pain or dysfunction. Excluding adjacent segment disease that occurred with a similar rate for patients who underwent fusion and arthroplasty, 5 patients, all treated with arthroplasty, returned for evaluation of neck and arm symptoms between 48 and 72 months after surgery. Four patients had peridevice vertebral body bone loss. One patient had posterior device migration and presented with myelopathy. Three required revision surgery and 2 were observed. Four patients maintained follow-up and reported stabilization or improvement in symptoms. Despite their similarities, CA and fusion are not equivalent procedures in this study in regard to very late complications. Similar to large joint arthroplasty, delayed device-related complications may occur with CA. These complications commenced well beyond the time frame for complications associated with more traditional cervical spine procedures. Both patients and surgeons should be aware of the potential for very late device-related complications occurring with CA and the need for revision surgery. 1.

New-onset diabetes mellitus (NODM) after liver transplantation is a common complication with a potentially negative impact on patient outcome. To evaluate the incidence of NODM and its impact on Asian adult living donor liver transplant (LDLT) recipients, we investigated 369 adult LDLT cases in our institute. Preoperative diabetes mellitus (DM) was diagnosed in 38 (9 %) patients. NODM was observed in 128/331 (38 %) patients, 56 (44 %) with persistent NODM and 72 (56 %) with transient NODM. The mean interval between LDLT and the development of NODM was 0.6 ± 1.8 (range 0-1.4) months. Multivariate analyssis revealed that older age, being male and having a higher body mass index were independent risk factors among recipients for developing NODM, while hepatitis C virus infection was not a significant risk factor, and DM had no impact on patient outcome. Although the long-term effect of DM on outcome remains to be investigated, the presence of DM after liver transplant, whether it was NODM or preexisting DM, had no impact on LDLT recipients' outcomes in mid-term. © 2013 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

Technical failure in pancreas transplant has been the main cause of the loss of grafts. In the last few years, the number of complications has reduced, and therefore the proportion of this problem. The Spanish Pancreas Transplant Group wanted to analyze the current situation with regard to surgical complications and their severity. A retrospective and multicenter study was performed. 10 centers participated, with a total of 410 pancreas transplant recipients between January and December 2013. A total of 316 transplants were simultaneous with kidney, 66 after kidney, pancreas-only 10, 7 multivisceral and 11 retrasplants. Surgical complication rates were 39% (n=161). A total of 7% vascular thrombosis, 13% bleeding, 6% the graft pancreatitis, 12% surgical infections and others to a lesser extent. Relaparotomy rate was 25%. The severity of complications were of type IIIb (13%), type II (12%) and type IVa (8.5%). Graft loss was 8%. Early mortality was 0.5%. The percentage of operations for late complications was 17%. The number of surgical complications after transplantation is not negligible, affecting one in 3 patients. They are severe in one out of 5 and, in one of every 10 patients graft loss occurs. Therefore, there is still a significant percentage of surgical complications in this type of activity, as shown in our country. Copyright © 2014 AEC. Publicado por Elsevier España, S.L.U.

2018-03-09

We investigated the incidence of gastrointestinal disorders requiring endoscopic and histopathologic diagnoses in renal transplant recipients. In this retrospective analysis, we examined records of patients seen at the Department of Hepato-Gastroenterology and Transplantation Sciences, Sindh Institute of Urology and Trans?lantation (Karachi, Pakistan) from January 2010 to December 2014. Renal transplant recipients with gastrointestinal disorders who required endoscopy, including proctoscopy and upper and lower gastrointestinal endoscopy as per indication, were included. Of 1770 patients included in this study, most were male patients (n = 1517; 85.7%). In this patient group, 1957 endoscopies, including proctoscopies, were performed, which included 1033 esophagogastroduodenoscopies (52.8%), 571 sigmoidoscopies (29.2%), and 107 colonoscopies (5.5%). The most common indications were diarrhea (n = 697; 31.2%) and weight loss (n = 690; 31%). Findings showed esophageal candidiasis in 127 patients (12%); however, biopsy revealed Candida species in 33 patients (34%). Cytomegalovirus and herpes esophagitis were observed in 8 (8.3%) and 5 patients (5.2%). Helicobacter pylori gastritis was seen in 119 patients (15.4%), cytomegalovirus gastritis in 9 patients (1.2%), and gastric lymphoma in 1 patient (0.1%). Duodenal fissuring was the most common pathology observed during endoscopy (396 patients; 33.9%), followed by decreased height of duodenal folds in 157 patients (13.4%), with biopsy showing sprue in 325 patients (37.6%) and giardiasis in 118 patients (13.7%). Lower gastrointestinal endoscopy showed ulcers in 198 patients (24.6%) and polyps in 31 patients (3.9%). Histopathologic examination showed cytomegalovirus colitis in 89 patients (15.5%), amebic colitis in 21 (3.7%), and tuberculosis in 11 (1.9%). We observed a wide spectrum of pathologic lesions, including opportunistic infections, in endoscopic biopsies from our renal transplant patients. Cytomegalovirus colitis was

1981-01-01

In spite of many advances in medicine, anesthetic technique and surgical managements, pulmonary problems are the most frequent postoperative complications, particularly after abdominal surgery. As postoperative pulmonary complications, atelectasis, pleural effusion, pneumonia, chronic bronchitis and lung abscess can be occurred. This study include evaluation of chest films of 2006 patients (927 male, 1079 female), who had been operated abdominal surgery from Jan. 1979 to June, 1980 in the Hanyang university hospital. The results were as follows: 1. 70 cases out of total 2006 cases (3.5%) developed postoperative chest complications, 51 cases (5.5%) in male, 19 cases (1.8%) in female. 2. The complication rate was increased according to the increase of age. The incidence of the postoperative complications over 40 years of age was higher than the overall average complications rate. 3. The most common postoperative pulmonary complication was pleural effusion, next pneumonia, atelectasis and pulmonary edema respectively. 4. The complication rate of the group of upper abdominal surgery is much higher than the group of lower abdominal surgery. 5. Complication rate was increased according to increase of the duration of operation. 6. There were significant correlations between the operation site and side of the complicated hemithorax

Hepatic encephalopathy in a liver transplant recipient with stable liver function.

Arab, Juan Pablo; Meneses, Luis; Pérez, Rosa M; Arrese, Marco; Benítez, Carlos

2013-04-01

Postshunt hepatic encephalopathy after liver transplantation (LT) is an infrequent condition and is commonly associated with portal occlusion or stenosis and the presence of a patent portosystemic shunt. Portal vein stenosis (PVS) or thrombosis (PVT) are uncommon complications after LT. The overall frequency of both complications is reported to be less than 3%. When PVS or PVT develop early after LT, the occlusion of the portal vein can have catastrophic consequences to the graft including acute liver failure and graft loss. Late PVT/PVS are asymptomatic in approximately 50% of the cases and mainly diagnosed by a routine ultrasound. Symptomatic postshunt hepatic encephalopathy (HE) is a very infrequent condition after LT that has been scarcely reported in the literature. We present here the case of a liver recipient with normal graft function who presented with hepatic encephalopathy 3 months after LT with stable liver function but a severe portal stenosis and the presence of a spontaneous portosystemic shunt whose successful endovascular treatment was followed by the complete resolution of the HE.

Full Text Available Use of an autologous latissimus flap in breast reconstruction accounts for a supple and natural look of reconstructed breast. Most common postoperative complication, seroma, became more of a rule then an exception when it comes to postoperative evaluation of the patients who underwent this reconstructive procedure. A retrospective study analysing and evaluating different complication rates in 20 patients who underwent breast reconstruction by autologous latissimus flap, was conducted. All patients included in the study were operated at the Department of plastic surgery of Hôpital Civil in Strasbourg, France, between 1996 and 2008. The complication rates were noted as follows: seroma in 19 of our 20 patients (95%, late hypertrophic scarring in 3 patients (15%, postoperative surgical site hematoma in 3 patients (15%, and 2 patients (10% presented postoperative chronic back pain. Different options used in seroma treatment and prevention (subcutaneous-fascia anchor sutures of donor site, application of corticosteroids by injection into donor site postoperatively, passive drainage can reduce seroma formation and thus overall complication rates, leading to much faster patient’s recovery time and return to normal daily activities.

Reconstruction of iliac crest with rib to prevent donor site complications: A prospective study of 26 cases

Directory of Open Access Journals (Sweden)

Dave B

2007-01-01

Full Text Available Background: The tricortical bone graft from the iliac crest are used to reconstruct the post corpectomy spinal defects. The donor iliac area defect is large and may give rise to pain at donor site, instability of pelvis, fracture of ilium, donor site muscle herniation or abdominal content herniation. Rib removed during thoracotomy was used by us to reconstruct the iliac crest defect. Materials and Methods: Twenty-six patients who underwent thoracotomy for dorsal spine corpectomy or curettage for various spinal pathologies from June 2002 to May 2004 were included in the study. After adequate decompression the spine was reconstructed by tricortical bone graft from iliac crest and reconstruction of the iliac crest was done with the rib removed for exposure during thoracotomy. Results: The mean follow up was 15 months. All patients had good graft incorporation which was evaluated on the basis of local tenderness and radiographs. One patient had graft displacement. Conclusion: The reconstruction of iliac crest by rib is a simple and effective procedure to prevent donor site complications.

The benefits of kidney transplantation in diabetic patients with peripheral vascular disease (PVD) are unclear. While patients may have improved survival compared to dialysis, the burden of care after transplant has not been assessed. We performed a retrospective review of adult diabetic kidney-only transplant recipients with and without PVD transplanted from January 2012 until June 30, 2015. Of 203 diabetic kidney transplant recipients, 56 (27.6%) had PVD and 147 (72.4%) had no PVD. At a median of 3.14 years follow up there were no significant differences in 30-, 90-, or 1-year readmission rates. At 1 year after transplant, PVD patients were significantly more likely to have a greater sum of unplanned inpatient days (44.6% versus 27.9% with ≥10 inpatient days, p=0.03) and at least one reoperation (28.6% vs. 8.7%, pPVD had significantly increased rates of non-graft related operations of which 31.2% were PVD related. Diabetic patients with PVD utilize more resources after kidney transplant, spending more time in the hospital and undergoing more post-transplant operations. The causes of readmission are predominantly related to progression of PVD rather than allograft complications. This article is protected by copyright. All rights reserved.

Oral health and dental maintenance have become part of the standard of care for pediatric liver transplant recipients. These individuals tend to suffer particularly from dental problems, such as gingival enlargement, gingivitis, poor oral hygiene, dental hypoplasia, and caries. Saliva composition influences oral hygiene and disease states. We investigated saliva composition and its association with the oral health of young recipients of liver transplants. In 70 patients, 36 liver transplant recipients (ages 2-23 years) and 34 healthy controls (ages 4-21 years), we measured the following variables: (a) oral hygiene, (b) gingival inflammation, (c) caries status, (d) dental calculus formation, (e) oral mucosal pH, and (f) salivary protein composition. Lower mean decayed, missing, and filled teeth index (P=0.0038), higher mean gingival index (P=0.0001), and higher mean calculus score (P=0.003) were found in the transplanted study group compared with the control. The mean mucosal pH for seven intraoral sites was higher in the transplant group (P=0.0006). The median salivary albumin concentration was significantly lower in the transplant group (P=0.01), as was the median salivary albumin/total protein ratio (P=0.0002). In post-liver transplant pediatric recipients, low incidence of caries, together with high incidence of dental calculus, could be attributed to elevated oral mucosal pH. Salivary albumin and immunoglobulin A levels were relatively low in these patients. Clinicians should pay particular attention to the oral health and dental care of liver transplanted children.

CMV Serostatus of Donor-Recipient Pairs Influences the Risk of CMV Infection/Reactivation in HSCT Patients

2012-01-01

Full Text Available CMV donor/recipient serostatus was analyzed in 200 patients allografted in our institution from unrelated (122 patients donors and 78 sibling donors in the years 2002–2011 in relation to posttransplant complications. On a group basis independently of the CMV serostatus of donor-recipient pairs sibling transplantations and those from unrelated donors that matched 10/10 at allele level had a similar rate of CMV reactivation (17/78 versus 19/71, P=ns. The rate of CMV reactivation/infection was higher in patients grafted from donors accepted at the lower level of matching than 10/10 (18/38 versus 36/149, P=0.008. The incidence of aGvHD followed frequencies of CMV reactivation in the tested groups, being 40/156 and 25/44 in patients grafted from sibling or unrelated donors that 10/10 matched and in those grafted from donors taht HLA mismatched, respectively (P=0.001. Regarding the rate of reactivation in both groups seropositive patients receiving a transplant from seronegative donors had more frequently CMV reactivation as compared to those with another donor-recipient matching CMV serostatus constellation (22/43 versus 32/143, P=0<0.001. Multivariate analysis revealed that seropositivity of recipients with concomitant seronegativity of donors plays an independent role in the CMV reactivation/infection (OR=2.669, P=0.037; OR=5.322, P=0.078; OR=23.034, P=0.023 for optimally matched and mismatched patients and the whole group of patients, resp..

Laparoscopic techniques are evolving for a wide range of surgical procedures although they were initially confined to cholecystectomy and exploratory laparoscopy. Recently, surgical procedures performed with a laparoscope include splenectomy, adrenalectomy, gastrectomy, and myomectomy. In this article, we review the spectrum of complications and illustrate imaging features of biliary and nonbiliary complications after various laparoscopic surgeries. Biliary complications following laparoscopic cholecystectomy include bile ductal obstruction, bile leak with bile duct injury, dropped stones in the peritoneal cavity, retained CBD stone, and port-site metastasis. Nonbiliary complications are anastomotic leakage after partial gastrectomy, gangrenous cholecystitis after gastrectomy, hematoma at the anastomotic site following gastrectomy, gastric infarction after gastrectomy, port-site metastasis after gastrectomy, hematoma after splenectomy, renal infarction after adrenalectomy, and active bleeding after myomectomy of the uterus.

Nonmelanoma skin cancer (NMSC) and associated premalignant lesions represent a major complication after transplantation, particularly in areas with high ultraviolet radiation (UVR) exposure. The American Society of Transplantation has proposed annual NMSC screening for all renal transplant recipients. The aim of this study was to develop a predictive index (PI) that could be used in targeted screening. Data on patient demographics, UVR exposure, and other clinical parameters were collected on 398 adult recipients recruited from the Princess Alexandra Hospital, Brisbane. Structured interview, skin examination, biopsy of lesions, and review of medical/pathologic records were performed. Time to presentation with the first NMSC was assessed using Cox's regression models and Kaplan-Meier estimates used to assess detection of NMSC during screening. Stepwise selection identified age, outdoor UVR exposure, living in a hot climate, pretransplant NMSC, childhood sunburning, and skin type as predictors. The PI generated was used to allocate patients into three screening groups (6 months, 2 years, and 5 years). The survival curves of these groups were significantly different (PPI to enable development of targeted NMSC surveillance strategies.

Full Text Available The role of infection with Mycoplasma hominis following cardiothoracic organ transplantation and its source of transmission have not been well-defined. Here, we identify and describe infection with M. hominis in patients following cardiothoracic organ transplantation after reviewing all cardiothoracic transplantations performed at our center between 1998 and July 2015. We found seven previously unreported cases of M. hominis culture positive infection all of whom presented with pleuritis, surgical site infection, and/or mediastinitis. PCR was used to establish the diagnosis in four cases. In two instances, paired single lung transplant recipients manifested infection, and in one of these pairs, isolates were indistinguishable by multilocus sequence typing (MLST. To investigate the prevalence of M. hominis in the lower respiratory tract, we tested 178 bronchoalveolar lavage (BAL fluids collected from immunocompromised subjects for M. hominis by PCR; all were negative. Review of the literature revealed an additional 15 cases of M. hominis in lung transplant recipients, most with similar clinical presentations to our cases. We recommend that M. hominis should be considered in post-cardiothoracic transplant infections presenting with pleuritis, surgical site infection, or mediastinitis. M. hominis PCR may facilitate early diagnosis and prompt therapy. Evaluation for possible donor transmission should be considered.

Full Text Available Introduction: Post-transplant lymphoproliferative syndrome (PTLD is a rare and potentially life-threatening complication after liver transplantation. The aim of this study was to analyze the clinicopathologic features related to PTLD in a single institution after liver transplantation. Methods: Observational study where we have retrospectively analyzed 851 cases who underwent liver transplantation. Ten cases have developed PTLD. Their clinical-pathological characteristics and the treatment received have been analyzed. Results: PTLD incidence was 1.2% (10/851. The mean time from liver transplantation to PTLD diagnosis was 36 months (range 1.2 to 144 months. PTLD localization was extranodal in all cases, the most frequent location being intestinal. Seven cases showed a monomorphic lymphoma which in all cases was differentiated B cell lymphomas. Fifty per cent of the series were seropositive for Epstein-Barr virus. Five patients were alive at the time of the review. Among these patients, we observed three cases of complete remission and two cases of disease stabilization. The death rate was higher in the first year after diagnosis of PTLD. Conclusion: PTLD is a rare complication after liver transplantation, but it may pose a threat to the life of a liver transplant recipient. It is essential to identify patients at risk, to establish an early diagnosis and treatment that can change the outcome of the disease.

Little is known about any differences between young people with chronic physical conditions who do and do not apply for disability benefits in young adulthood for providing insights for future policy and rehabilitation care. We aimed to identify predictors during adolescence of receiving disability benefits in young adulthood and to compare recipients and non-recipients of benefits in social participation and psychosocial outcomes in young adulthood. Follow-up study of 18 to 25 year olds with various chronic conditions who at adolescent age completed a web-based survey (n=518; T0). The outcome was receiving disability benefits (yes or no). Associations with background characteristics, social participation, and impact of the chronic condition were explored with stepwise multivariate modelling, using T0 variables. Differences between recipients and non-recipients were explored using chi-square tests and t-tests. Receiving disability benefits in young adulthood was associated with greater extent of physical disability, receiving less special education, absenteeism at school/work, and low health-related quality of life during adolescence. In young adulthood, recipients of benefits reported higher perceived impact of the chronic condition on their school/work career and lower quality of life than non-recipients. Social participation varied across domains. This study provides important insights into the characteristics of a vulnerable subgroup of young people with chronic physical conditions. Disability benefit recipients experienced more impact of their chronic condition and reported a lower health-related quality of life over time than non-recipients. Rehabilitation professionals are encouraged to use patient-reported outcomes to address the lived experiences and screen the need for psychosocial support of this vulnerable subgroup of young people with chronic physical conditions.

We performed single-photon emission computed tomography (SPECT) to investigate the influence of renal transplantation on cerebral blood flow (CBF). Fifteen renal transplant recipients and twelve normal subjects underwent cerebral SPECT with N-isopropyl-p-[ 123 I] iodoamphetamine ( 123 I-IMP). All transplant recipients received prednisolone and cyclosporine (CyA). Regional CBF (rCBF) was measured by defining regions of interest in the cerebral cortex, deep white matter, striatum, thalamus, and cerebellum. In transplant recipients, correlations to the mean overall cortical CBF were assessed using the interval from transplantation to measurement of SPECT, as well as the serum creatinine concentration. Moreover, to investigate the influence of CyA on CBF, the correlation between mean overall cortical CBF and CyA trough concentrations was assessed. In all regions, CBF in renal transplant recipients was significantly lower than in normal subjects. No significant correlation was seen between serum creatinine, interval from transplantation, or CyA trough concentrations and mean overall cortical CBF. Renal transplant recipients demonstrated a decrease in CBF, that can have an associated secondary pathology. Therefore, renal transplant recipients may benefit from post-operative MRI or CT.

Despite advances in surgical techniques and products for stoma care, stoma-related complications are still common. A retrospective analysis was performed of the medical records of 462 consecutive patients (295 [63.9%] female, 167 [36.1 %] male, mean age 55.5 ± 15.1 years, mean body mass index [BMI] 25.1 ± 5.2) who had undergone stoma creation at the Gastroenterological Surgery Clinic of Turkiye Yuksek İhtisas Teaching and Research Hospital between January 2008 and December 2012 to examine the incidence of early (ie, within 30 days after surgery) stoma complications and identify potential risk factors. Variables abstracted included gender, age, and BMI; existence of malignant disease; comorbidities (diabetes mellitus, hypertension, coronary artery disease, chronic respiratory disease); use of neoadjuvant chemoradiotherapy; permanent or temporary stoma; type of stoma (loop/end stoma); stoma localization; and the use of preoperative marking of the stoma site. Data were entered and analyzed using statistical software. Descriptive statistics, chi-squared, and Mann-Whitney U tests were used to describe and analyze all variables, and logistic regression analysis was used to determine independent risk factors for stoma complications. Ostomy-related complications developed in 131 patients (28.4%) Of these, superficial mucocutaneous separation was the most frequent complication (90 patients, 19.5%), followed by stoma retraction (15 patients, 3.2%). In univariate analysis, malignant disease (P = .025), creation of a colostomy (P = .002), and left lower quadrant stoma location (P toma complication. Only stoma location was an independent risk factor for the development of a stoma complication (P = .044). The rate of stoma complications was not significantly different between patients who underwent nonemergent surgery (30% in patients preoperatively sited versus 28.4% not sited) and patients who underwent emergency surgery (27.1%). Early stoma complication rates were higher

Full Text Available Other-regarding preferences are a critical feature of human cooperation but to what extent non-human animals exhibit these preferences is a matter of intense discussion. We tested whether jackdaws show prosocial behaviour (providing benefits to others at no cost to themselves and altruism (providing benefits to others while incurring costs with both sibling and non-sibling recipients. In the prosocial condition, a box was baited on both the actor's and the recipient's side (1/1 option, whereas another box provided food only for the actor (1/0 option. In the altruistic condition, the boxes contained food for either the actor (1/0 option or the recipient (0/1 option. The proportion of selfish (1/0 option and cooperative (1/1 and 0/1 option, respectively actors' choices was significantly affected by the recipients' behaviour. If recipients approached the boxes first and positioned themselves next to the box baited on their side, trying to access the food reward (recipient-first trials, actors were significantly more cooperative than when the actors approached the boxes first and made their choice prior to the recipients' arrival (actor-first trials. Further, in recipient-first trials actors were more cooperative towards recipients of the opposite sex, an effect that was even more pronounced in the altruistic condition. Hence, at no cost to the actors, all recipients could significantly influence the actors' behaviour, whereas at high costs this could be achieved even more so by recipients of different sex. Local/stimulus enhancement is discussed as the most likely cognitive mechanism to account for these effects.

Solid organ transplant (SOT) recipients are at greater risk than the general population for complications and mortality from influenza infection. Researchers and clinicians with experience in SOT infections have developed this consensus document in collaboration with several Spanish scientific societies and study networks related to transplant management. We conducted a systematic review to assess the management and prevention of influenza infection in SOT recipients. Evidence levels based on the available literature are given for each recommendation. This article was written in accordance with international recommendations on consensus statements and the recommendations of the Appraisal of Guidelines for Research and Evaluation II (AGREE II). Recommendations are provided on the procurement of organs from donors with suspected or confirmed influenza infection. We highlight the importance of the possibility of influenza infection in any SOT recipient presenting upper or lower respiratory symptoms, including pneumonia. The importance of early antiviral treatment of SOT recipients with suspected or confirmed influenza infection and the necessity of annual influenza vaccination are emphasized. The microbiological techniques for diagnosis of influenza infection are reviewed. Guidelines for the use of antiviral prophylaxis in inpatients and outpatients are provided. Recommendations for household contacts of SOT recipients with influenza infection and health care workers in close contact with transplant patients are also included. Finally antiviral dose adjustment guidelines are presented for cases of impaired renal function and for pediatric populations. The latest scientific information available regarding influenza infection in the context of SOT is incorporated into this document. Copyright © 2013 Elsevier España, S.L. All rights reserved.

Renal transplantation is the treatment of choice for most patients with end stage renal disease (ESRD). This procedure provides a survival benefit compared to hemodialysis and is also cost effective. The aim of this study is to identify the types and incidence rates of complications that effect renal transplant recipients admitted to the intensive care unit (ICU) during long-term follow-up and to examine the impact of these complications on the length of hospital stay as well as mortality in a tertiary closed ICU in Saudi Arabia. We reviewed the data of all adult renal transplant recipients who were admitted to the ICU at the King Abdulaziz Medical City, Riyadh between May 1999 and October 2006. During the stay period, 80 patients had a total of 96 ICU admissions; 49% were females. The admission APACHE II score and expected mortality was 25+7 and 48+23 respectively. The hospital mortality rate was 42%. Sepsis was major indication for ICU admission and pneumonia was the main cause of sepsis. In multivariate analysis the following variables were introduced in the model: APACHE II score, age, Glasgow Coma Score and need for hemodialysis in the ICU. We found only the need for hemodialysis during the ICU as an independent risk factor for mortality (P<0.02). We found in this study that the main reason for ICU admissions among renal transplant recipients was infections. Mortality rates for this particular population are relatively high and are primarily linked to the need for dialysis. (author)

Cardiovascular complications after transplantation are an important cause of non-transplant-related deaths. Depression and anxiety are not unusual among organ recipients. Physical activity reduces cardiovascular risk and promotes a sensation of well-being. The aims of the study were to examine how exercise affects psychological well-being sensation in organ recipients and to describe the physician's role in promoting and controlling safe sport training in transplanted patients. A descriptive study was conducted. A questionnaire was answered by participants of the "2012 Latin American Transplant Games." One hundred sixty-six organ recipients completed the questionnaire. Eleven percent heard about the transplant games from a physician. Seventy percent had not received a proper medical pre-competitive evaluation. Only 39% trained in a supervised manner and 53% had experienced some kind of sport-related injury. Self-perception of global health was reported as excellent by 19.75%, very good by 43.95%, good by 30.67%, and regular or poor by 5.73%. An excellent or very good health perception was reported by 47.8% of those who practiced only one kind of sport versus 71.5% of those who practiced more than one sport and by 89.6% of those who performed isometric activity versus 59.3% of those who did not perform isometric activity. Diversity of practiced sports and isometric activity are associated with a better self-reported health condition. Most participants had not received a proper medical pre-competitive evaluation; they trained in an unsupervised manner, and injuries were common. Copyright © 2016 Elsevier Inc. All rights reserved.

To analyze the cause and effect of magnet dislocation in cochlear implant (CI) recipients requiring magnet revision surgery for treatment. Retrospective study. Tertiary referral center. Case reports from 1,706 CI recipients consecutively implanted from January 2000 to December 2011 were reviewed. The number of cases requiring magnet revision surgery was assessed. Revision surgery involving magnet removal or replacement was indicated in 1.23% (21/1,706), of all CI recipients. Magnet dislocation occurring during magnetic resonance tomography (MRI), at 1.5 Tesla (T), with the magnet in place and with the application of compression bandaging around the head, was the main cause for revision surgery in 47.62% (10/21) of the affected cases. All 10 cases were implanted with Cochlear Nucleus cochlear implants. These events occurred, despite adherence to current recommendations of the manufacturer. The present study underlines that MRI examination is the main cause of magnet dislocation. The use of compressive bandaging when using 1.5-T MRI does not eliminate the risk of magnet dislocation. Additional cautionary measures are for required for conditional MRI. We recommend X-ray examination after MRI to determine magnet dislocation and avoid major complications in all cases reporting pain during or after MRI. Additional research regarding silicon magnet pocket design for added retention is needed. Effective communication of guidelines for precautionary measures during MRI examination in CI patients is mandatory for all clinicians involved. MRI in CI recipients should be indicated with caution.

Full Text Available Aim of study: multiplex analysis of the levels of biomarkers of neoangiogenesis and inflammation in cardiac transplant recipients. Materials and methods. 59 pts. with heart failure III–IV according to NYHA FC, waiting for a heart transplant, aged 22 to 73 years, 48 males and 11 females. 41 recipient (30 men and 11 women had dilated cardiomyopathy, 18 – coronary heart disease (CHD. The concentration of VEGF-A, VEGF-D, PlGF, PDGF-BB, FGF, sCD40L, MCP-1 was measured using xMAP technology, the sets of reagents Simplex ProcartaPlexTM (Affymetrix, USA. Results. There are four levels of seven biomarkers of neoangiogenesis and inflammation method for multiplex analysis in patients with heart failure. A year after transplantation, the mean levels of biomarkers VEGF-A (p = 0.001, PDGF-BB (p = 0.018, MCP-1 (p = 0.003 was significantly decreased, and the others had a tendency to decrease relative to the level before transplantation. It was shown individual differences of levels of VEGF-A, VEGF-D and PlGF before and after transplantation. There were found different dynamics of the concentrations of biomarkers and growth factors before and after heart transplantation in patients with cardiovascular complications and without them. Conclusion. Multiplex analysis allows to measure the concentration range of analyte biomarkers of neoangiogenesis, inflammation in one sample of blood serum of patients with severe heart failure and after transplantation. There are marked individual differences in the concentration of biomarkers in different clinical situations that may have clinical significance in the conduct and supervision of recipients after transplantation.

Influenza vaccine strategies for solid organ transplant recipients.

Hirzel, Cédric; Kumar, Deepali

2018-05-15

The aim of this study was to highlight recent evidence on important aspects of influenza vaccination in solid organ transplant recipients. Influenza vaccine is the most evaluated vaccine in transplant recipients. The immunogenicity of the vaccine is suboptimal after transplantation. Newer formulations such as inactivated unadjuvanted high-dose influenza vaccine and the administration of a booster dose within the same season have shown to increase response rates. Intradermal vaccination and adjuvanted vaccines did not show clear benefit over standard influenza vaccines. Recent studies in transplant recipients do not suggest a higher risk for allograft rejection, neither after vaccination with a standard influenza vaccine nor after the administration of nonstandard formulation (high-dose, adjuvanted vaccines), routes (intradermally) or a booster dose. Nevertheless, influenza vaccine coverage in transplant recipients is still unsatisfactory low, potentially due to misinterpretation of risks and benefits. Annual influenza vaccination is well tolerated and is an important part of long-term care of solid organ transplant recipients.

To review available data describing the epidemiology, outcomes, prevention, and treatment of influenza virus in the solid organ transplant population and to evaluate the strengths and limitations of the current literature, with a focus on literature reviewing annual influenza strains and the recent pandemic novel influenza A/H1N1 strain. A systematic literature search (July 1980-June 2011) was performed via PubMed using the following key words: influenza, human; influenza; novel influenza A H1/N1; transplantation; solid organ transplantation; kidney transplant; renal transplant; lung transplant; heart transplant; and liver transplant. Papers were excluded if they were not written in English or were animal studies or in vitro studies. Data from fully published studies and recent reports from international conferences were included. The influenza virus presents a constant challenge to immunocompromised patients and their health care providers. The annual influenza strain introduces a highly infectious and pathogenic risk to solid organ transplant recipients. In 2009, the World Health Organization declared a pandemic as a result of a novel influenza A/H1N1 strain. The pandemic introduced an additional viral threat to solid organ transplant patients at increased risk for infectious complications. The mainstay for prevention of influenza infection in all at-risk populations is appropriate vaccination. Antiviral therapies against influenza for chemoprophylaxis and treatment of infection are available; however, dosing strategies in the solid organ transplant population are not well defined. The solid organ transplant population is at an increased risk of severe complications from influenza infection. Identifying risks, preventing illness, and appropriately treating active infection is essential in this patient population.

The results of studies on the association between sex mismatch and survival after heart transplantation are conflicting. Data from the Spanish Heart Transplantation Registry. From 4625 recipients, 3707 (80%) were men. The donor was female in 943 male recipients (25%) and male in 481 female recipients (52%). Recipients of male hearts had a higher body mass index (25.9 ± 4.1 vs. 24.3 ± 3.7; P gender (P = 0.02). In the multivariate analysis, sex mismatch was associated with long-term mortality (HR, 1.14; 95% CI 1.01-1.29; P = 0.04), and there was a tendency toward significance for the interaction between sex mismatch and recipient gender (P = 0.08). In male recipients, mismatch increased mortality mainly during the first month and in patients with pulmonary gradient >13 mmHg. Sex mismatch seems to be associated with mortality after heart transplantation in men but not in women. © 2014 Steunstichting ESOT.

Full Text Available The aim of our study is to determine characteristics and outcomes of kidney cancer in renal transplant recipients. MEDLINE ® database was searched in June 2015 to identify cases of kidney cancer in renal transplant recipients. We include also a new case. Descriptive statistics were used for analysis. Forty-eight (48 recipients reported in 25 papers met the eligibility criteria. The median age was 47 years (range 9-66; 27% were females. Chronic glomerulonephritis, cystic kidney disease and hypertension were common indications for renal transplant. Among donors 24% were females and the median age was 52.5 years (17- 73; 62% of kidney cancers were donor-derived. The median interval between transplant and cancer diagnosis was shorter for cancer of recipient versus donor origin (150 vs. 210 days. Clear cell carcinoma was diagnosed in 17%. 25% had metastasis at diagnosis. Kidney explantation or excision was done in 90% and 84% of cases with and without metastasis respectively. The median survival was 72 months. Actuarial 1-year and 5-year survival rates were 73.4% and 55.1% respectively. Among the recipients from 7 donors who subsequently developed malignancy, 57% were dead within a year. Kidney transplant recipients have a small risk of kidney cancer, which affects younger patients and occurs within a year of transplant, likely due to immunosuppression. Whether the use of older donors may increase the likelihood needs further investigation. The presence of metastasis, explantation or excision of affected kidney and development of cancer in donors predict outcomes. The results may guide patient education and informed decision-making.

Early detection of subclinical lung function decline may help identify allogeneic hematopoietic cell transplant (HCT) recipients who are at increased risk for late noninfectious pulmonary complications, including bronchiolitis obliterans syndrome. We evaluated the use of handheld spirometry in this population. Allogeneic HCT recipients enrolled in a single-center observational trial performed weekly spirometry with a handheld spirometer for 1 year after transplantation. Participants performed pulmonary function tests in an outpatient laboratory setting at 3 time points: before transplantation, at day 80 after transplantation, and at 1 year after transplantation. Correlation between the 2 methods was assessed by Pearson and Spearman correlations; agreement was assessed using Bland-Altman plots. A total of 437 subjects had evaluable pulmonary function tests. Correlation for forced expiratory volume in 1 second (FEV1) was r = .954 (P spirometry correlated well with laboratory spirometry after allogeneic HCT and may be useful for self-monitoring of patients for early identification of airflow obstruction.

Serum creatinine (Scr) is the most frequently used test to estimate graft function after kidney transplantation. Our previous study demonstrated that the independent predictors of recipient posttransplantation Scr included the ratio of graft weight to recipient body weight, the ratio of graft weight to recipient body surface area (BSA), and the ratio of graft weight to recipient body mass index (BMI). A prospective analysis about the impact of the balance between metabolic demands and renal supply on posttransplantation Scr of recipients was previously reported. We plotted the scatter graph using the X-axis as the independent predictors of Scr by linear regression and the Y-axis as the recipient Scr. To generate the predictive formula of Scr, we calculated a fit of the line of plotted cases using a linear regression method with 2 regression lines for prediction of the upper and lower 95% confidence intervals. Each line was converted into a predictive formula: Scr = -0.0033* (Graft weight(g)/Recipient BSA(m2))+1.75. Under 95% confidence, the Scr ranges from -0.0033* (Graft weight(g)/Recipient BSA(m2))+1.07 to -0.0033* (Graft weight(g)/Recipient BSA (m2))+2.44. Scr = -0.1049* (Graft weight(g)/Recipient body weight(kg))+1.72, which ranges from -0.1049* (Graft weight(g)/Recipient body weight(kg))+1.06 to -0.1049* (Graft weight(g)/Recipient body weight(kg))+2.37. Scr = -0.0158* (Graft weight(g)/Recipient BMI(kg/m2))+1.56, which ranges from -0.0158* (Graft weight(g)/Recipient BMI(kg/m2))+0.75 to -0.0158* (Graft weight(g)/Recipient BMI(kg/m2))+2.26. Prediction of posttransplantation Scr may be achieved by measuring graft weight as well as recipient weight and height. When recipient Scr is significantly higher than that predicted by the formula, a clinician should suspect an underlying graft injury.

To compare new onset dyslipidaemia in live-related renal transplant recipients taking cyclosporine versus tacrolimus after 3 months of therapy. The randomised controlled trial was conducted at the Sindh Institute of Urology and Transplantation (SIUT) Karachi, from September 2010 to April 2011, and included 182 End Stage Renal Disease patients on maintenance haemodialysis with pre-transplant normal lipid profile. The patients, who had live-related renal transplant, were randomly allocated to two equal groups using lottery. Group A received cyclosporine (3 mg/kg) and group B was treated with tacrolimus (0.1 mg/kg). All patients had pre-transplant fasting lipid profile checked when they were on maintenance haemodialysis and 3 months after renal transplantation. Serum fasting lipid profile was collected by taking 5 ml blood by venipuncture after an overnight fast of 9-12 hours. SPSS 10 was used for statistical analyses. Of the 182 patients, 144 (79.1%) were males and 38 (20.9%) were females. The overall mean age was 30.18 +/- 9.57 years, and the mean weight was 54.41 +/- 11.144 kg. Significant difference was not observed between the two groups regarding age and weight of the patients. Dyslipidaemia was found in 115(63.2%) subjects; 61(67%) in group A and 54 (59.3%) in group B. There was no statistical difference (p=0.28) when comparison was done after 3 months of therapy. The occurrence of new onset hyperlipidaemia is similar in renal transplant recipients receiving either cyclosporine or tacrolimus in first 3 months post-transplant, but there is room for more research in this field as dyslipidaemia following successful renal transplantation is a frequent and persistent complication.

Neurologic complications are common after hematopoietic stem cell transplantation (HSCT) and solid organ transplantation (SOT) and affect 30-60% of transplant recipients. The aim of this article is to provide a practical imaging approach based on the timeline and etiology of CNS abnormalities, and neurologic complications related to transplantation of specific organs. The lesions will be classified based upon the interval from HSCT procedure: pre-engraftment period <30 days, early post-engraftment period 30-100 days, late post-engraftment period >100 days, and the interval from SOT procedure: postoperative phase 1-4 weeks, early posttransplant syndromes 1-6 months, late posttransplant syndromes >6 months. Further differentiation will be based on etiology: infections, drug toxicity, metabolic derangements, cerebrovascular complications, and posttransplantation malignancies. In addition, differentiation will be based on complications specific to the type of transplantation: allogeneic and autologous hematopoietic stem cells (HSC), heart, lung, kidney, pancreas, and liver. Thus, in this article we emphasize the strategic role of neuroradiology in the diagnosis and response to treatment by utilizing a methodical approach in the work up of patients with neurologic complications after transplantation.

Social networking sites like Facebook may be a powerful tool for increasing rates of live kidney donation. They allow for wide dissemination of information and discussion and could lessen anxiety associated with a face-to-face request for donation. However, sparse data exist on the use of social media for this purpose. We searched Facebook, the most popular social networking site, for publicly available English-language pages seeking kidney donors for a specific individual, abstracting information on the potential recipient, characteristics of the page itself, and whether potential donors were tested. In the 91 pages meeting inclusion criteria, the mean age of potential recipients was 37 (range: 2-69); 88% were US residents. Other posted information included the individual's photograph (76%), blood type (64%), cause of kidney disease (43%), and location (71%). Thirty-two percent of pages reported having potential donors tested, and 10% reported receiving a live-donor kidney transplant. Those reporting donor testing shared more potential recipient characteristics, provided more information about transplantation, and had higher page traffic. Facebook is already being used to identify potential kidney donors. Future studies should focus on how to safely, ethically, and effectively use social networking sites to inform potential donors and potentially expand live kidney donation. © 2013 John Wiley & Sons A/S.

Mortality rates in complicated peptic ulcer disease are high. This study aimed to examine the prognostic importance of ulcer site in patients with peptic ulcer bleeding (PUB) and perforated peptic ulcer (PPU). a nationwide cohort study with prospective and consecutive data collection. all patients treated for PUB and PPU at Danish hospitals between 2003 and 2014. demographic and clinical data reported to the Danish Clinical Registry of Emergency Surgery. 90- and 30-d mortality and re-intervention. the crude and adjusted association between ulcer site (gastric and duodenal) and the outcome measures of interest were assessed by binary logistic regression analysis. Some 20,059 patients with PUB and 4273 patients with PPU were included; 90-d mortality was 15.3% for PUB and 29.8% for PPU; 30-d mortality was 10.2% and 24.7%, respectively. Duodenal bleeding ulcer, as compared to gastric ulcer (GU), was associated with a significantly increased risk of all-cause mortality within 90 and 30 d, and with re-intervention: adjusted odds ratio (OR) 1.47 (95% confidence interval 1.30-1.67); p ulcers (DUs) in PPU patients: adjusted OR 0.99 (0.84-1.16); p = 0.698, OR 0.93 (0.78 to 1.10); p = 0.409, and OR 0.97 (0.80-1.19); p = 0.799, respectively. DU site is a significant predictor of death and re-intervention in patients with PUB, as compared to GU site. This does not seem to be the case for patients with PPU.

Mentors play important roles in training new investigators. This study was designed to determine characteristics of NIH mentored K award recipients and their mentors, their interpersonal interactions, and the factors, which influence satisfaction within this relationship. A survey of 3027 NIH mentored K recipients and 1384 mentors was conducted in 2009. Nine hundred twenty-nine (30.7%) of the K recipients and 448 (32.4%) mentors completed the survey. The gender of K respondents was evenly divided while the mentors were 72.1% male. The overall rating of their mentors was positive. Ideally, both thought the mentor should be important in research training; however, in actual practice, both rated the importance as lower. A total of 88.2% of recipients were satisfied with their relationship. Although the number of black K recipients was low, this group was more likely to be dissatisfied with the mentor relationship (6/29 or 20.7%) than their white counterparts. The frequency of meeting or communicating was correlated with K recipient satisfaction. Overall K recipients are satisfied with their mentor relationships. Although the number of black K recipient respondents was small, the higher level of mentor dissatisfaction should be further evaluated. Qualities of mentors, including the frequency of interactions and accessibility, can influence satisfaction. © 2012 Wiley Periodicals, Inc.

Park, Hyoung-Chul; Kim, Min Jeong; Lee, Bong Hwa

Although it is accepted that complicated appendicitis requires antibiotic therapy to prevent post-operative surgical infections, consensus protocols on the duration and regimens of treatment are not well established. This study aimed to compare the outcome of post-operative infectious complications in patients receiving old non-standardized and new standard antibiotic protocols, involving either 5 or 10 days of treatment, respectively. We enrolled 1,343 patients who underwent laparoscopic surgery for complicated appendicitis between January 2009 and December 2014. At the beginning of the new protocol, the patients were divided into two groups; 10 days of various antibiotic regimens (between January 2009 and June 2012, called the non-standardized protocol; n = 730) and five days of cefuroxime and metronidazole regimen (between July 2012 and December 2014; standardized protocol; n = 613). We compared the clinical outcomes, including surgical site infection (SSI) (superficial and deep organ/space infections) in the two groups. The standardized protocol group had a slightly shorter operative time (67 vs. 69 min), a shorter hospital stay (5 vs. 5.4 d), and lower medical cost (US$1,564 vs. US$1,654). Otherwise, there was no difference between the groups. No differences were found in the non-standardized and standard protocol groups with regard to the rate of superficial infection (10.3% vs. 12.7%; p = 0.488) or deep organ/space infection (2.3% vs. 2.1%; p = 0.797). In patients undergoing laparoscopic surgery for complicated appendicitis, five days of cefuroxime and metronidazole did not lead to more SSIs, and it decreased the medical costs compared with non-standardized antibiotic regimens.

The AMS/DOE graduate fellowships were awarded to three students entering their first year of graduate study. The funds allowed each student to take a full course load during their first of year of graduate study which helps each of them to enter the professional, scientific community at an earlier date. Each recipient is academically outstanding, received glowing references of support and demonstrated their strong desire to perform scientific research. As part of the fellowship, each of the students was invited to attend the AMS Annual Meeting where they got to participate in the AMS student conference, attend scientific sessions and visit the exhibition hall. In addition, a student awards luncheon was held where each of the recipients got to meet their sponsor and receive a certificate.

Selection of ideal recipient vessels is one of the most important factors determining success in free-flap reconstruction of the lower limb. At the knee, the choice of vessels has traditionally been either the common femoral or the popliteal vessels and their branches but these are often difficult to use or cannot be used. A series of 32 free flaps for cover of complex injuries of the knee involving the distal femur, the knee joint and the upper tibia were reconstructed using the descending genicular branch of the femoral artery in the adductor canal and its muscular branches to the vastus medialis as the recipient vessels. All but one flap survived with no major complications. The use of the descending genicular artery as the recipient vessel for reconstruction with free flaps around the knee has various advantages including: (i) it is mostly remote from the zone of trauma, (ii) it is constant in location, (iii) the recipient vessels are an excellent size match for end-to-end anastomosis, (iv) there is no need for changes of position of the patient when using most free flaps commonly used for knee reconstruction, (v) it is easy to harvest these simultaneously, (vi) secondary exposure of the underlying skeleton from all quadrants is unlikely to divide the flap pedicle as it is superior and (vii), perhaps most important of all, it obviates the need for exploration of the popliteal fossa.

To compare donor site morbidity in patients who have undergone fibula free flap reconstruction in which the skin graft was taken from the expected cutaneous paddle of the fibula with the known complications of the popular technique of obtaining a split-thickness skin graft (STSG) from a secondary donor site. Cohort study. The tertiary care centers at Loma Linda University Medical Center and University of California, Los Angeles, Medical Center. From September 1, 2006, to March 30, 2007, 30 patients underwent fibula free flap harvest by 2 surgeons at separate tertiary care centers. Twenty-one of those procedures took place at the University of California, Los Angeles, and 9 at Loma Linda University. Patients included 15 men (50%) and 15 women (50%), with a mean age of 58 (range, 19-88) years. All 30 patients underwent fibula free flap harvest with a split-thickness skin graft (graft thickness, 0.04 cm), obtained from osteocutaneous paddle using a 5.1-cm-wide dermatome, as well as oral cavity and oropharyngeal reconstruction with the de-epithelialized skin paddle. Measures of donor site morbidity, including graft failure and wound breakdown, and measures of recipient site morbidity, including flap failure, hardware complications, intraoral complications, and the need for additional surgery. Of the 30 patients who underwent this procedure, 4 had partial skin graft failures, for a complete skin graft survival of 87%. There were no complete skin graft losses. Regarding the fibula osteocutaneous free flap, there were no complete flap losses, 1 skin paddle necrosis that required debridement, 2 postoperative orocutaneous fistulas, 1 case of infected/extruded hardware, and 1 adhesion formation that required additional surgery for lysis of adhesion and placement of the split-thickness skin graft. The outlined novel technique has similar rates of free flap survival and skin graft take compared with previously described methods. Harvesting the skin graft over the expected

Renal transplantation with a well-functioning graft leads to a rapid restoration of endocrine and sexual functions. The aim of this study was to examine our experience with pregnancies among renal transplant patients, particularly with regard to their impact on graft function. We analyzed 10 pregnancies in 7 renal transplant recipients for long-term graft outcomes in terms of clinical and biological data. The mean patient age was 28.5 +/- 4 years. They all received a living donor kidney. The time between transplantation and the onset of pregnancy was 33.4 +/- 23.2 months. Regarding the immunosuppressive therapy, all patients received steroids and cyclosporine; 4 patients received in addition azathioprine and 2 received mycophenolate mofetil that was changed at 1 month before conception to azathioprine. There was no significant difference between the serum creatinine before and during pregnancy. We did not observe any acute rejection episode. Pregnancy complications were preclampsia in 1 case, hypertension in 1 case, urinary tract infection in 2 cases, and anemia in 80% of patients during the third trimester. Premature rupture of membranes occurred in 1 case and preterm delivery in 2 cases. Two cases of neonatal death were registered. Cesarean section was performed in 50% of cases. The follow-up revealed 2 cases of chronic rejection. A multidisciplinary approach is necessary for pregnancy which generally occurs at 2 years after kidney transplantation.

BACKGROUND Post-transplant lymphoproliferative disorder (PTLD) is a potential complication of solid organ or bone marrow transplants. The main PTLD risk factors are: the Epstein-Barr virus (EBV), transplant type, and use of immunosuppressants. It mainly consists of an uncontrolled growth of lymphocytes in transplant recipients under chronic immunosuppressive therapy. About 85% of PTLDs are EBV-containing B-cell proliferations; 14% are T-cell proliferations, of which only 40% contain EBV; and the remaining 1% is NK-cell or plasmocyte proliferations. PTLD may present various clinical manifestations, from non-specific mononucleosis-like syndrome to graft or other organ damage resulting from pathologic lymphocyte infiltration. PTLD may manifest in the oral cavity. CASE REPORT The objective of this study was to present the case of a 13-year-old female living-donor liver transplant recipient, resulting from biliary cirrhosis caused by congenital biliary atresia, with exophytic fibrous lesions on buccal mucosa and tongue. Exophytic and hyperplastic lesion of oral mucosa were removed and histopathological examination revealed polymorphic PTLD. The patient underwent 6 cycles of CHOP chemotherapy and all the oral lesions regressed completely. CONCLUSIONS All oral pathological lesions in organ transplant recipients need to be surgically removed and histopathologically examined because they present an increased risk of neoplastic transformations such as PTLD.

Objectives: To compare new onset dyslipidaemia in live-related renal transplant recipients taking cyclosporine versus tacrolimus after 3 months of therapy. Methods: The randomised controlled trial was conducted at the Sindh Institute of Urology and Transplantation (SIUT) Karachi, from September 2010 to April 2011, and included 182 End Stage Renal Disease patients on maintenance haemodialysis with pre-transplant normal lipid profile. The patients, who had live-related renal transplant, were randomly allocated to two equal groups using lottery. Group A received cyclosporine (3mg/kg) and group B was treated with tacrolimus (0.1mg/kg). All patients had pre-transplant fasting lipid profile checked when they were on maintenance haemodialysis and 3 months after renal transplantation. Serum fasting lipid profile was collected by taking 5ml blood by venipuncture after an overnight fast of 9-12 hours. SPSS 10 was used for statistical analyses. Results: Of the 182 patients, 144(79.1%) were males and 38(20.9%) were females. The overall mean age was 30.18+-9.57 years, and the mean weight was 54.41+- 11.144kg. Significant difference was not observed between the two groups regarding age and weight of the patients. Dyslipidaemia was found in 115(63.2%) subjects; 61(67%) in group A and 54(59.3%) in group B. There was no statistical difference (p=0.28) when comparison was done after 3 months of therapy. Conclusions: The occurrence of new onset hyperlipidaemia is similar in renal transplant recipients receiving either cyclosporine or tacrolimus in first 3 months post-transplant, but there is room for more research in this field as dyslipidaemia following successful renal transplantation is a frequent and persistent complication.

Little is known about the specific sexual concerns of kidney transplant (KTx) recipients. The primary objectives of this study were to: (i) describe the importance of sexuality to KTx recipients; (ii) investigate the sexual concerns of KTx recipients; and (iii) examine the relationship between sexual concerns and quality of life (QOL). A secondary objective was to examine potential sexual concern differences by gender, pre-transplant dialysis status, and donor type. This study employed a cross-sectional, descriptive, correlational design. Sexual concerns were identified using the Sexual Concerns Questionnaire, which contains seven subscales. QOL was measured with the SF-8 and the QOL Uniscale. Nearly 73% of subjects rated sexuality as important. Subscales indicating highest area of sexual concerns were communication with healthcare providers about sexuality (Mean (M) = 2.70) and sexual pleasure concerns (M = 2.45). Higher concern ratings regarding health consequences of sexual activity, quality of sexual relationship, sexual pleasure, sexual functioning problems, and pessimistic beliefs about treatment were significantly, inversely related to QOL. Women had significantly higher scores on the Sexual Pleasure and Communication with Healthcare Providers subscales than men. This study reports the sexual concerns of KTx recipients' who are an average of four yr since surgery, and the relationship of these concerns to QOL. © 2014 John Wiley & Sons A/S.

Experimental X-ray injuries of the skin were created on guineapigs with contact therapy conditions with a total dose of 14,000 or 12,000R. Measurements of the skin temperature and heat release of the skin show that regardless of whether the donor or recipient site was injured, a reproduction of the plethora and a reduction of the blood circulation of antologous, free full thickness skin grafts was brought about compared to control grafts if the operation was performed 2 - 3 weeks after ending irradiation. Extensively corresponding results were obtained if the operation was performed 5 months after terminating irradiation; however, an increased blood circulation was detected on the 7th post-operative day with the pre-injury of the graft bed. Corresponding measurements on 10 human full thickness skin grafts with radiation-injured graft bed and 15 comparison grafts also showed a negative influence of the revascularisation by the X-ray injury of the graft bed.

In living donor liver transplantation (LDLT), the recipient bile duct is thin and short. Bile duct complications often occur in LDLT, with persistent long-term adverse effects. Recently, we began to perform microsurgical reconstruction of the bile duct. The purpose of this study was to investigate the relationship between bile duct reconstruction methods and complications in LDLT. From 1991 to 2014, we performed 161 LDLTs (pediatric:adult = 90:71; left lobe:right lobe = 95:66). In this study, we retrospectively investigated the initial bile duct complications in LDLT and performed univariate and multivariate analyses to identify the independent risk factors for complications. The most frequent complication was biliary stricture (9.9%), followed by biliary leakage (6.8%). On univariate and multiple logistic regression analysis, the independent risk factors for biliary stricture were bile leakage (P = .0103) and recurrent cholangitis (P = .0077). However, there were no risk factors for biliary leakage on univariate analysis in our study. The reconstruction methods (hepaticojejunostomy or duct-to-duct anastomosis) and reconstruction technique (with or without microsurgery) were not risk factors for biliary stricture and leakage. In this study, the most frequent complication of LDLT was biliary stricture. The independent risk factors for biliary stricture were biliary leakage and recurrent cholangitis. Duct-to-duct anastomosis and microsurgical reconstruction of the bile duct were not risk factors for biliary stricture and leakage. Copyright © 2016 Elsevier Inc. All rights reserved.

In spite of improvements in single or double lung transplantation (LT) technique, complications after LT are not uncommon; the most frequent ale anastomotic complications, infections and rejection (acute or chronic). Early detection of complications of LT allows the optimal therapeutic option to be taken, yielding decreased morbidity and mortality. In some cases, CT plays a key role in early detection of several complications of LT that may not be depicted with other diagnostic modalities, so that knowledge of their CT features is important. In this pictorial review, the authors describe the spectrum of CT features of the complications of LT (including reimplantation response, mechanical problems, acute and chronic rejection, infection, lymphoproliferative disorders, recurrence of the initial disease and complications involving the pleura and the anastomotic sites). In addition, the authors analyze the value of CT compared to that of the other available modalities for the detection of complications of LT. (orig.). With 19 figs

Diagnosis and management of ureteral complications following renal transplantation

Directory of Open Access Journals (Sweden)

Brian D. Duty

2015-10-01

Full Text Available When compared with maintenance dialysis, renal transplantation affords patients with end-stage renal disease better long-term survival and a better quality of life. Approximately 9% of patients will develop a major urologic complication following kidney transplantation. Ureteral complications are most common and include obstruction (intrinsic and extrinsic, urine leak and vesicoureteral reflux. Ureterovesical anastomotic strictures result from technical error or ureteral ischemia. Balloon dilation or endoureterotomy may be considered for short, low-grade strictures, but open reconstruction is associated with higher success rates. Urine leak usually occurs in the early postoperative period. Nearly 60% of patients can be successfully managed with a pelvic drain and urinary decompression (nephrostomy tube, ureteral stent, and indwelling bladder catheter. Proximal, large-volume, or leaks that persist despite urinary diversion, require open repair. Vesicoureteral reflux is common following transplantation. Patients with recurrent pyelonephritis despite antimicrobial prophylaxis require surgical treatment. Deflux injection may be considered in recipients with low-grade disease. Grade IV and V reflux are best managed with open reconstruction.

Objective: To evaluate the therapeutic effect of interventional treatment via radial artery access for diabetic foot and to summarize its complications and nursing care. Methods: The interventional treatment via radial artery access was performed in twenty patients with diabetic foot. The preoperative psychological nursing care, the nursing of the punctured site of radial artery and the indwelling catheter, the complications of the puncture site and thrombolytic therapy were reviewed and retrospectively analyzed. Results: Some complications occurred in eight cases, including hematoma at puncture site (n= 1), oozing of blood (n=3), gingival bleeding (n=1) and pain (n=3). No retention of urine or infection occurred. Conclusion: It is very important to pay enough attention to the nursing care of puncture site and indwelling catheter sheath and to make a close observation of patient's condition in order to reduce the occurrence of complications. Rich clinical experience and careful observation after the operation can definitely reduce the occurrence of thrombolytic complications and improve the patient's living quality. (authors)

Over the last decade, liver transplantation of sicker, older non-hepatitis C cirrhotics with multiple co-morbidities has increased in the United States. We sought to identify an easily applicable set of recipient factors among HCV negative adult transplant recipients associated with significant morbidity and mortality within five years after liver transplantation. We collected national (n = 31,829, 2002-2015) and center-specific data. Coefficients of relevant recipient factors were converted to weighted points and scaled from 0-5. Recipient factors associated with graft failure included: ventilator support (five patients; hazard ratio [HR] 1.59; 95% CI 1.48-1.72); recipient age >60 years (three patients; HR 1.29; 95% CI 1.23-1.36); hemodialysis (three patients; HR 1.26; 95% CI 1.16-1.37); diabetes (two patients; HR 1.20; 95% CI 1.14-1.27); or serum creatinine ≥1.5 mg/dl without hemodialysis (two patients; HR 1.15; 95% CI 1.09-1.22).

Radiofrequency ablation is an efficacious alternative in patients with symptomatic atrial fibrillation who do not respond to or are intolerant to at least one class I or class III antiarrhythmic drug. Although radiofrequency ablation is a safe procedure, complications can occur. Depending on the location, these complications can be classified into those that affect the pulmonary veins themselves, cardiac complications, extracardiac intrathoracic complications, remote complications, and those that result from vascular access. The most common complications are hematomas, arteriovenous fistulas, and pseudoaneurysms at the puncture site. Some complications are benign and transient, such as gastroparesis or diaphragmatic elevation, whereas others are potentially fatal, such as cardiac tamponade. Radiologists must be familiar with the complications that can occur secondary to pulmonary vein ablation to ensure early diagnosis and treatment. Copyright © 2016 SERAM.

Population-based evidence of the relative risk of cancer among heart, kidney, and liver transplant recipients from Asia is lacking. The Taiwan National Health Insurance Research Database was used to conduct a population-based cohort study of transplant recipients (n = 5396), comprising 801 heart, 2847 kidney, and 1748 liver transplant recipients between 2001 and 2012. Standardized incidence ratios and Cox regression models were used. Compared with the general population, the risk of cancer increased 3.8-fold after heart transplantation, 4.1-fold after kidney transplantation and 4.6-fold after liver transplantation. Cancer occurrence showed considerable variation according to transplanted organs. The most common cancers in all transplant patients were cancers of the head and neck, liver, bladder, and kidney and non-Hodgkin lymphoma. Male recipients had an increased risk of cancers of the head and neck and liver, and female kidney recipients had a significant risk of bladder and kidney cancer. The adjusted hazard ratio for any cancer in all recipients was higher in liver transplant recipients compared with that in heart transplant recipients (hazard ratio = 1.5, P = .04). Cancer occurrence varied considerably and posttransplant cancer screening should be performed routinely according to transplanted organ and sex.

Full Text Available Introduction: Kidney transplant is the first-line therapy for end-stage renal disease. Patients over 60 constitute a population which is increasingly affected by this disease. However, they do not receive timely transplantation and most of them stay on dialysis treatment with a reduction of their survival time and life quality. In this study we show the results of the kidney transplants between elderly patients performed at a private tertiary care hospital in Cali, Colombia. Methods: This descriptive, cohort study includes 31 kidney transplants with donors and recipients over 60, which were carried out at Fundación Valle del Lili in Cali, Colombia, from January 2002 to March 2016. Results: The average ages were 66 for recipients and 65 for donors. In most cases (90% deceased donors were involved. The main cause of renal disease was diabetic nephropathy. Conclusion: The survival rate for the patients who underwent this procedure at the center mentioned above is similar to the results shown in the literature all over the world. The most common complications associated with this kind of operation are malignancy, infections and cardiovascular pathologies. Candidates for this transplantation should be carefully chosen given its complexity and related complications.

MUSIC APPRECIATION AND TRAINING FOR COCHLEAR IMPLANT RECIPIENTS: A REVIEW

Science.gov (United States)

Looi, Valerie; Gfeller, Kate; Driscoll, Virginia

2012-01-01

In recent years, there has been increasing interest in music perception of cochlear implant (CI) recipients, and a growing body of research conducted in this area. The majority of these studies have examined perceptual accuracy for pitch, rhythm, and timbre. Another important, but less commonly studied aspect of music listening is appreciation, or appraisal. Despite the ongoing research into potential technological improvements that may improve music perception for recipients, both perceptual accuracy and appreciation generally remain poor for most recipients. Whilst perceptual accuracy for music is important, appreciation and enjoyment also warrants research as it also contributes to clinical outcomes and perceived benefits. Music training is being shown to offer excellent potential for improving music perception and appreciation for recipients. Therefore, the primary topics of this review are music appreciation and training. However, a brief overview of the psychoacoustic, technical, and physiological factors associated with a recipient’s perception of music is provided, as these are important factors in understanding the listening experience for CI recipients. The purpose of this review is to summarize key papers that have investigated these issues, in order to demonstrate that i) music enjoyment and appraisal is an important and valid consideration in evaluating music outcomes for recipients, and ii) that music training can improve music listening for many recipients, and is something that can be offered to persons using current technology.

Full Text Available Objective: The purpose of the study is to report and to analyze the complications following intratympanic injections (ITI of steroids. The occurrence rate of complications at different ITI sites, four quadrants of eardrum, was also compared. Methods: A retrospective clinical review in a medical center. Each patient received ITI twice in a week for 2–3 consecutive weeks as a salvage therapy for sudden sensorineural hearing loss. Post-injection complications, especially transient dizziness and vertigo, were recorded. Patients with acute or chronic vertigo episodes in 1 month were excluded. Results: A total of 59 patients with sudden sensorineural hearing loss and a total of 278 times of ITI were performed in 1 year. The post-injection complications included pain, tongue numbness, transient dizziness, vertigo, tinnitus, and a small persistent perforation. There was no significant difference in the occurrence of these complications between the injections sites on the 4 quadrants of the tympanic membrane. However, there was statistical significance in the post-injection vertiginous episode after IT injections to posterior-inferior quadrant (Q3 and posterior-superior quadrant (Q4 compared to anterior-superior quadrant (Q1 and anterior-inferior quadrant (Q2 (P = 0.0113. Conclusion: IT injection is recommended to be applied to the Q2 since the Q1 and Q4 injections are more likely to induce the adverse effect of tongue numbness, while the Q3 and Q4 areas are more likely to induce post-injection vertigo.

Bémeur, Chantal; Butterworth, Roger F

2014-06-01

Malnutrition is a common feature of chronic liver diseases that is often associated with a poor prognosis including worsening of clinical outcome, neuropsychiatric complications as well as outcome following liver transplantation. Nutritional assessment in patients with cirrhosis is challenging owing to confounding factors related to liver failure. The objectives of nutritional intervention in cirrhotic patients are the support of liver regeneration, the prevention or correction of specific nutritional deficiencies and the prevention and/or treatment of the complications of liver disease per se and of liver transplantation. Nutritional recommendations target the optimal supply of adequate substrates related to requirements linked to energy, protein, carbohydrates, lipids, vitamins and minerals. Some issues relating to malnutrition in chronic liver disease remain to be addressed including the development of an appropriate well-validated nutritional assessment tool, the identification of mechanistic targets or therapy for sarcopenia, the development of nutritional recommendations for obese cirrhotic patients and liver-transplant recipients and the elucidation of the roles of vitamin A hepatotoxicity, as well as the impact of deficiencies in riboflavin and zinc on clinical outcomes. Early identification and treatment of malnutrition in chronic liver disease has the potential to lead to better disease outcome as well as prevention of the complications of chronic liver disease and improved transplant outcomes.

adverse birth experience can be distressing for men and some may report symptoms of birth trauma. Being informed by and receiving support from midwives and other health professionals appears to help mitigate the negative impact of birth complications. Effective support may help address men's confusion about their role, however genuinely including men as recipients of care or service in pregnancy, labour and birth raises important questions about whether the father is also a recipient of maternity care and if the transition to fatherhood is itself becoming a medical event?

Marcus, E A; Wozniak, L J; Venick, R S; Ponthieux, S M; Cheng, E Y; Farmer, D G

2015-04-01

Pregnancy after solid organ transplantation is becoming more common, with the largest recorded numbers in renal and liver transplant recipients. Intestinal transplantation is relatively new compared to other solid organs, and reports of successful pregnancy are far less frequent. All pregnancies reported to date in intestinal transplant recipients have been in women with stable graft function. The case reported here involves the first reported successful term pregnancy in an intestine-pancreas transplant recipient with chronic graft dysfunction and dependence on both transplant immunosuppression and parenteral nutrition (PN) at the time of conception. Pregnancy was unplanned and unexpected in the setting of chronic illness and menstrual irregularities, discovered incidentally on abdominal ultrasound at approximately 18 weeks' gestation. Rapamune was held, tacrolimus continued, and PN adjusted to maintain consistent weight gain. A healthy female infant was delivered vaginally at term. Medical complications during pregnancy included anemia and need for tunneled catheter replacements. Ascites and edema were improved from baseline, with recurrence of large volume ascites shortly after delivery. Successful pregnancy is possible in the setting of transplant immunosuppression, chronic intestinal graft dysfunction, and long-term PN requirement, but close monitoring is required to ensure the health of mother and child.

Kidney transplantation in recipients with a previous malignancy is often deferred 2 to 5 years after cancer treatment due to fear of cancer recurrence. In Norway, the required waiting period has been 1 year. We compared patient and graft survival of recipients with pretransplant cancer to the outcomes of matched recipients without such cancer (comparators) using Cox regression. From 1963 to 2010, 377 (6.4%) of 5867 recipients had a pretransplant cancer. During a median follow-up of 6.8 years, 256 recipients died, 35 (13.7%) from recurrent cancer and 27 (10.5%) from de novo cancer. Uncensored and death-censored graft loss occurred in 263 and 46 recipients, respectively. All-cause mortality was similar as in comparators (hazard ratio [HR], 1.06; 95% confidence interval [CI], 0.93-1.20]; P = 0.40), death-censored graft loss was lower (HR, 0.63; 95% CI, 0.47-0.84; P = 0.002), and uncensored graft loss was similar (HR, 0.99; 95% CI, 0.87-1.12; P = 0.87). Cancer mortality was higher than in comparators (HR, 1.97; 95% CI, 1.51-2.56; P cancer mortality or all-cause mortality (both P > 0.45). Results were similar within cancer subgroups, with most data in patients with a history of kidney cancer, prostate cancer, urothelial cancer, and skin squamous cell carcinoma. Kidney transplant recipients with a pretransplant cancer had a similar overall patient and graft survival as recipients without such cancer. Cancer mortality was increased, particularly during the first 5 years after transplantation. A short waiting period was not associated with mortality.

Simultaneous pancreas and kidney transplantation (SPK) is currently the best therapeutic option for patients with type 1 diabetes and terminal renal failure. Renal transplantation restores fertility enabling women to pursue pregnancies. However, scarcity of available data on pregnancy outcomes in SPK impedes fair medical counseling. Medical files of all pregnancies that lasted ≥3 months among recipients of functional SPK performed between 1990 and 2015 in France were retrospectively analyzed. Twenty-six pregnancies in 22 SPK recipients were identified. Main maternal complications included gestational hypertension (53.8%) and infections (50%). Cesarean section was performed in 73% of cases. Overall fetal survival was 92.6% with a mean gestational age of 34.2 ± 3 weeks. Four children (16.7% of live births) had a birth weight pregnancy. An acute kidney rejection occurred in two patients, one of which resulting in graft loss. Kidney and pancreas graft survival was, respectively, 96% and 100% at 1 year postconception and did not differ from controls. Pregnancy in SPK is feasible, but patients should be informed of the risks for the fetus, the mother, and the grafts. Planning of pregnancy in SPK women is key to allow a personalized multidisciplinary monitoring, which represents the most straightforward approach to optimize outcomes. © 2017 Steunstichting ESOT.

Extra-pulmonary tuberculosis (TB) is more common in renal allograft recipients and may present with dissemination or an atypical features. We report a renal allograft recipient with intestinal TB presenting 3 years after transplantation with persistent fever, weight loss, diarrhea, abdominal pain and mass in the abdomen with intestinal obstruction. He was diagnosed to be having an ileocolic intussusception which on resection showed a granulomatous inflammation with presence of acid-fast bacilli (AFB) typical of Mycobacterium tuberculosis. In addition, AFB was detected in the tracheal aspirate, indicating dissemination. He received anti-TB therapy (ATT) from the fourth postoperative day. However, he developed a probable immune reconstitution inflammatory syndrome (IRIS) with multiorgan failure and died on 11(th) postoperative day. This is the first report of intestinal TB presenting as intussusception in a renal allograft recipient. The development of IRIS after starting ATT is rare in renal allograft recipients. This report highlights the need for a high index of suspicion for diagnosing TB early among renal transplant recipients and the therapeutic dilemma with overwhelming infection and development of IRIS upon reduction of immunosuppression and starting ATT.

To describe procedure-specific types, rates, and risk factors for postdischarge (PD) complications occurring within 30 days after 21 groups of inpatient general surgery procedures. Retrospective cohort study. American College of Surgeons National Surgical Quality Improvement Program 2005 through 2010 Participant Use Data Files. A total of 551,510 adult patients who underwent one of 21 groups of general surgery procedures in the inpatient setting. Postdischarge complications, reoperation, and mortality. Of 551,510 patients (mean age, 54.6 years), 16.7% experienced a complication; 41.5% occurred PD. Of the PD complications, 75.0% occurred within 14 days PD. Proctectomy (14.5%), enteric fistula repair (12.6%), and pancreatic procedures (11.4%) had the highest PD complication rates. Breast, bariatric, and ventral hernia repair procedures had the highest proportions of complications that occurred PD (78.7%, 69.4%, and 62.0%, respectively). For all procedures, surgical site complications, infections, and thromboembolic events were the most common. Occurrence of an inpatient complication increased the likelihood of a PD complication (12.5% vs 6.2% without an inpatient complication; P surgery; those whose PD complication was preceded by an inpatient complication had the highest rates of reoperation (33.7%) and death (24.7%) (all P < .001). After adjustment, PD complications were associated with procedure type, American Society of Anesthesiologists class higher than 3, and steroid use. The PD complication rates vary by procedure, are commonly surgical site related, and are associated with mortality. Fastidious, procedure-specific patient triage at discharge as well as expedited patient follow-up could improve PD outcomes.

Perceptions of donors and recipients regarding blood donation.

The aim of this study was to identify the perceptions of blood donors and recipients regarding the act of donating blood. This descriptive study with a survey design focuses on subjective and cultural aspects. Twenty donors and 20 recipients in the blood bank at the time of data collection participated in the study. Interviews were analyzed according to deductive thematic analysis. Two themes emerged - perceptions of donors and perceptions of recipients. Both groups saw the act of donating blood as something positive, though donors associated their reports with the experiences of people close to them who needed blood transfusions, while the recipients associated donations with the maintenance of their lives as, for them, a blood transfusion was a necessary medical treatment. Perceptions regarding blood donations are culturally constructed, as the participants associated knowledge acquired in the social world with moral issues and their life experiences. Hence, in addition to helping others, these individuals feel socially and morally rewarded. Copyright © 2016 Associação Brasileira de Hematologia, Hemoterapia e Terapia Celular.

Kidney transplantation is the treatment choice for patients with end-stage renal diseases. Because of good long-term outcome, pediatric kidney grafts are also accepted for transplantation in adult recipients despite a significant mismatch in body size and age between donor and recipient. These grafts show a remarkable ability of adaptation to the recipient body and increase in size in a very short period, presumably as an adaptation to hyperfiltration. We investigated renal graft growth as well as glomerular proliferation and differentiation markers Kiel-67, paired box gene 2 and Wilms tumor protein (WT1) expression in control biopsies from different transplant constellations: infant donor for infant recipient, infant donor for child recipient, infant donor for adult recipient, child donor for child recipient, child donor for adult recipient, and adult donor for an adult recipient. We detected a significant increase in kidney graft size after transplantation in all conditions with a body size mismatch, which was most prominent when an infant donated for a child. Podocyte WT1 expression was comparable in different transplant conditions, whereas a significant increase in WT1 expression could be detected in parietal epithelial cells, when a kidney graft from a child was transplanted into an adult. In kidney grafts that were relatively small for the recipients, we could detect reexpression of podocyte paired box gene 2. Moreover, the proliferation marker Kiel-67 was expressed in glomerular cells in grafts that increased in size after transplantation. Kidney grafts rapidly adapt to the recipient size after transplantation if they are transplanted in a body size mismatch constellation. The increase in transplant size is accompanied by an upregulation of proliferation and dedifferentiation markers in podocytes. The different examined conditions exclude hormonal factors as the key trigger for this growth so that most likely hyperfiltration is the key trigger inducing the

Flash fluorescence with indocyanine green videoangiography to identify the recipient artery for bypass with distal middle cerebral artery aneurysms: operative technique.

Science.gov (United States)

Rodríguez-Hernández, Ana; Lawton, Michael T

2012-06-01

Distal middle cerebral artery (MCA) aneurysms frequently have nonsaccular morphology that necessitates trapping and bypass. Bypasses can be difficult because efferent arteries lie deep in the opercular cleft and may not be easily identifiable. We introduce the "flash fluorescence" technique, which uses videoangiography with indocyanine green (ICG) dye to identify an appropriate recipient artery on the cortical surface for the bypass, enabling a more superficial and easier anastomosis. Flash fluorescence requires 3 steps: (1) temporary clip occlusion of the involved afferent artery; (2) videoangiography demonstrating fluorescence in uninvolved arteries on the cortical surface; and (3) removal of the temporary clip with flash fluorescence in the involved efferent arteries on the cortical surface, thereby identifying a recipient. Alternatively, temporary clips can occlude uninvolved arteries, and videoangiography will demonstrate initial fluorescence in efferent arteries during temporary occlusion and flash fluorescence in uninvolved arteries during reperfusion. From a consecutive series of 604 MCA aneurysms treated microsurgically, 22 (3.6%) were distal aneurysms and 11 required a bypass. The flash fluorescence technique was used in 3 patients to select the recipient artery for 2 superficial temporal artery-to-MCA bypasses and 1 MCA-MCA bypass. The correct recipient was selected in all cases. The flash fluorescence technique provides quick, reliable localization of an appropriate recipient artery for bypass when revascularization is needed for a distal MCA aneurysm. This technique eliminates the need for extensive dissection of the efferent artery and enables a superficial recipient site that makes the anastomosis safer, faster, and less demanding.

Recipient design in human communication: simple heuristics or perspective taking?

Science.gov (United States)

Blokpoel, Mark; van Kesteren, Marlieke; Stolk, Arjen; Haselager, Pim; Toni, Ivan; van Rooij, Iris

2012-01-01

Humans have a remarkable capacity for tuning their communicative behaviors to different addressees, a phenomenon also known as recipient design. It remains unclear how this tuning of communicative behavior is implemented during live human interactions. Classical theories of communication postulate that recipient design involves perspective taking, i.e., the communicator selects her behavior based on her hypotheses about beliefs and knowledge of the recipient. More recently, researchers have argued that perspective taking is computationally too costly to be a plausible mechanism in everyday human communication. These researchers propose that computationally simple mechanisms, or heuristics, are exploited to perform recipient design. Such heuristics may be able to adapt communicative behavior to an addressee with no consideration for the addressee's beliefs and knowledge. To test whether the simpler of the two mechanisms is sufficient for explaining the "how" of recipient design we studied communicators' behaviors in the context of a non-verbal communicative task (the Tacit Communication Game, TCG). We found that the specificity of the observed trial-by-trial adjustments made by communicators is parsimoniously explained by perspective taking, but not by simple heuristics. This finding is important as it suggests that humans do have a computationally efficient way of taking beliefs and knowledge of a recipient into account.

Background There are limited published data on the characteristics of blood transfusion recipients in sub-Saharan Africa. This study describes the demographic characteristics of blood transfusion recipients and patterns of blood and blood component use in Zimbabwe. Materials and methods Data on the characteristics of the blood transfusion recipients (age, sex, blood group), blood components received (type, quantity), discharge diagnoses and outcomes following transfusion (discharge status, duration of stay in hospital), were retrospectively collected from four major hospitals for the period from January 1, 2012 to December 31, 2012. Diagnoses were grouped into broad categories according to the disease headings of the International Classification of Diseases (ICD-10). Surgical procedures were grouped into broad categories according to organ system using ICD-9. Results Most of the 1,793 transfusion recipients studied were female (63.2%) and in the reproductive age group, i.e. 15–49 years (65.3%). The median age of the recipients was 33 years (range, 0–93). The majority of these recipients (n=1,642; 91.6%) received a red blood cell transfusion. The majority of the patients were diagnosed with conditions related to pregnancy and childbirth (22.3%), and diseases of blood and blood-forming organs (17.7%). The median time spent in hospital was 8 days (range, 0–214) and in-hospital mortality was 15.4%. Discussion Our sample of blood transfusion recipients were fairly young and most of them received red blood cell transfusions. The majority of patients in the reproductive age group received blood transfusions for pregnancy and childbirth-related diagnoses. PMID:26192782

Robotic Assisted Radical Cystoprostatectomy and Intracorporeal Ileal Conduit Urinary Diversion for a Kidney Transplant Recipient

Directory of Open Access Journals (Sweden)

Peter A. Caputo

Full Text Available ABSTRACT Introduction and Objectives: Robotic assisted radical cystectomy (RARC is an alternative to open radical cystectomy. As experience is gained with the RARC approach the technique is being applied to more complex surgical cases. We describe here our technique for RARC with intracorporeal ileal conduit urinary diversion for a renal transplant recipient. Materials and Methods: The patient is a 60-year old man with high-grade muscle invasive bladder cancer. He has a history of renal failure due to polycystic kidney disease and received a deceased donor renal transplant in 2008. His hospital course at time of transplant was complicated by low-level BK virus viremia. Interestingly his trans-urethral bladder tumor resection specimen at time of bladder cancer diagnosis stained positive for SV40. His native kidneys were anuric so bilateral laparoscopic nephrectomy was performed in a staged fashion 2 weeks prior to RARC. Our surgical technique utilizes 6 trocars, of note a 12-mm assistant trocar is placed 1 cm superior to the pubic symphysis, and this trocar is solely used to pass a laparoscopic stapler to facilitate the excision of the ileal segment and the stapled enteric anastomosis. Surgical steps include: identification of native ureters bilaterally (removed en bloc with the bladder specimen; identification of the transplanted ureter at the right bladder dome; posterior bladder and prostate dissection along Denonvilliers’ fascia; development of the space of Retzius; ligation and transection of the bladder and prostate vascular bundles; apical prostate dissection and transection of urethra; left pelvic lymphadenectomy; ilium resection for creation of the ileal conduit; stapled enteric anastomosis; ureteroileal anastomosis; maturation of the ileal conduit stoma. Results: The surgery had no intraoperative complications. Operative time was 443 minutes (7.4 hours. Estimated blood loss was 250 cc. Length of hospital stay was 5 days. The patient

Full Text Available Medical centers that work with transplants often face opportunisticinfections that demand specific tools to make diagnosis. Theprevalence of latent polyomavirus infections is high, and the mostcommon site of latency of the most prevalent polyomavirus in humans,BK virus (BKV, is the renal tissue. Hence, renal transplanted patientsare particularly vulnerable to the damage caused by viral reactivationduring immunosupression. In such patients BKV is associated toureteral stenosis and/or BKV nephropathy, leading to progressivedysfunction and graft loss, often diagnosed as rejection. In other organsrecipients (namely lung, liver, heart and pancreas, BKN is also the mostimportant clinical manifestation, whereas in bone marrow recipients themost common is hemorrhagic cystitis. This review presents the viralbiology and discusses the pathophysiology of polyomavirus diseasesand the diagnostic efficacy of the laboratory tests available, guidingto the best strategy for assessment and monitoring of patients at riskor under specific treatment.

Achieving optimum outcomes after liver transplantation requires an understanding of the interaction between donor, graft and recipient factors. Within the cohort of patients waiting for a transplant, better matching of the donor organ to the recipient will improve transplant outcomes and benefit the overall waiting list by minimizing graft failure and need for re-transplantation. A PubMed search was conducted to identify published literature investigating the effects of donor factors such as age, gender, ethnicity, viral serology; graft factors such as size and quality, recipient factors such as age, size, gender and transplant factors such as major or minor blood group incompatibility and immunological factors. We also report technical and therapeutic modifications that can be used to manage donor-recipient mismatch identified from literature and the authors' clinical experience. Multiple donor and recipient factors impact graft survival after liver transplantation. Appropriate matching based on donor-organ-recipient variables, modification of surgical technique and innovative peri-transplant strategies can increase the donor pool by utilizing grafts from marginal donors that are traditionally turned down.

European senior programme (ESP) is well known for acceptable outcomes using expanded criteria donor (ECD) kidneys from donors older than 65 years for recipients older than 65 years. The incidence of end-stage renal disease (ESRD) is 229/million in India with a mean age of 45 years. We performed a retrospective analysis of transplantation of ECD versus standard criteria donor (SCD) kidneys into younger recipients. Forty-three ECD transplantations among 158 deceased donor organ transplantation (DDOT) were performed between January 2006 and December 2009. Among 43 transplantation from 30 donors, 14 were dual kidney transplantations (DKT) performed based upon biopsy evaluation. All recipients received thymoglobulin (rATG) induction followed by immunosuppression with a steroid, mycophenolate mofetil (MMF), and a calcineurin inhibitor. Statistical analysis used chi-square test and unpaired Student t test. Kaplan-Meier curves were used for survival analysis. For ECD the mean donor age was 64 ± 11 years. Cerebrovascular accidents (CVA) were the cause of death among 60% of donors, 73.13% of whom were hypertensive and 23.13% diabetic. Mean DKT donor age was 75 ± 9.17 years versus 60 ± 8.0 years for single kidney transplantation (SKT). Mean recipient age of DKT versus SKT was 44 ± 12.4 years versus 43 ± 14 years. Mean serum creatinine (SCr; mg/dL) of SKT patients was 1.64 ± 0.75 versus 1.68 ± 0.46 in DKT. Mean follow-up was 455 ± 352 days. Mean SCr of 43 ECD recipients of mean age, 43.4 ± 14.2 years was 1.61 ± 0.61 mg/dL. Among 43 recipients, 23.25% were diabetic, 41.86% displayed delayed graft function (DGF), and 23.25% experienced biopsy-proven acute rejection (BPAR). Patient survival rate was 72.09% and graft survival rate was 67.44%. For SCD transplantations (n = 115), the mean donor age was 36 ± 14 years and recipient mean age was 32.8 ± 14.07 years. Mean SCr was 1.32 ± 0.46 mg/dL with 26.95% recipients displaying DGF, whereas 20.86% had BPAR. In the SCD

Full Text Available Trocar site hernias are rare complications after laparoscopic surgery but most commonly occur at larger trocar sites placed at the umbilicus. With increased utilization of the laparoscopic approach the incidence of trocar site hernia is increasing. We report a case of a trocar site hernia following an otherwise uncomplicated robotic prostatectomy at a 12 mm right lower quadrant port. The vermiform appendix was incarcerated within the trocar site hernia. Subsequent appendectomy and primary repair of the hernia were performed without complication.

Invasive fungal diseases (IFD) are severe complications in patients receiving immunosuppression after solid organ or allogeneic stem cell transplantation. Extensive study has been conducted on therapeutic strategies for IFD in neutropenic patients, mostly those with hematological malignancy. There is an ongoing discussion on whether these studies may be applied to transplant patients as well. We have reviewed relevant literature on transplantation and clinical mycology of the last 20 years and selected articles relevant for today's treatment decisions. This article reports on the epidemiology of IFD in transplant recipients and current antifungal drugs in the context of tansplantation medicine. For invasive aspergillosis and invasive candidiasis, we give a detailed report of current clinical evidence. This review is intended as a quick-start for clinicians and other care providers new to transplant care and as an update for experienced transplant physicians. In a field in which evidence is scarce and conflicting, we provide evidence-based strategies for diagnosing and treating the most relevant IFD in transplant recipients. Physicians treating transplant patients should maintain a high level of awareness towards IFD. They should know the local epidemiology of IFD to make the optimal decision between current diagnostic and therapeutic strategies. Prophylaxis or early treatment should be considered given the high mortality of IFD.

Zonulin and iron metabolism in heart transplant recipients.

2014-10-01

In patients after heart transplantation, anemia is relatively common and is associated with impaired kidney function, subclinical inflammatory state, and immunosuppressive treatment. Zonulin-prehaptoglibin-2 is newly discovered protein with poorly defined function. Hemoglobin binds haptoglobin, and this stable complex prevents oxidative stress caused by hemoglobin. Zonulin is necessary for integrity of intracellular tight junction in the gut. Taking into consideration iron metabolism, including its absorption in the gut, the aim of this study was to assess zonulin levels in heart transplant recipients and their possible correlations with iron status, immunosuppressive therapy, and kidney function. The study was performed with 80 stable heart transplant recipients and 22 healthy volunteers. Zonulin, iron status, and inflammatory markers were assessed with the use of commercially available kits. Zonulin correlated with intraventricular diameter (r = 0.30; P zonulin and iron status. Zonulin was significantly lower in heart transplant recipients than in healthy volunteers (P zonulin level. Zonulin, despite its effect on the absorption of different nutrients and other substances and hypothethic role in oxidative stress, seems not to play a role in the pathogenesis of anemia in heart transplant recipients. Its physiologic role remains obscure.

Graft Growth and Podocyte Dedifferentiation in Donor-Recipient Size Mismatch Kidney Transplants

Directory of Open Access Journals (Sweden)

Janina Müller-Deile, MD

2017-10-01

Full Text Available Background. Kidney transplantation is the treatment choice for patients with end-stage renal diseases. Because of good long-term outcome, pediatric kidney grafts are also accepted for transplantation in adult recipients despite a significant mismatch in body size and age between donor and recipient. These grafts show a remarkable ability of adaptation to the recipient body and increase in size in a very short period, presumably as an adaptation to hyperfiltration. Methods. We investigated renal graft growth as well as glomerular proliferation and differentiation markers Kiel-67, paired box gene 2 and Wilms tumor protein (WT1 expression in control biopsies from different transplant constellations: infant donor for infant recipient, infant donor for child recipient, infant donor for adult recipient, child donor for child recipient, child donor for adult recipient, and adult donor for an adult recipient. Results. We detected a significant increase in kidney graft size after transplantation in all conditions with a body size mismatch, which was most prominent when an infant donated for a child. Podocyte WT1 expression was comparable in different transplant conditions, whereas a significant increase in WT1 expression could be detected in parietal epithelial cells, when a kidney graft from a child was transplanted into an adult. In kidney grafts that were relatively small for the recipients, we could detect reexpression of podocyte paired box gene 2. Moreover, the proliferation marker Kiel-67 was expressed in glomerular cells in grafts that increased in size after transplantation. Conclusions. Kidney grafts rapidly adapt to the recipient size after transplantation if they are transplanted in a body size mismatch constellation. The increase in transplant size is accompanied by an upregulation of proliferation and dedifferentiation markers in podocytes. The different examined conditions exclude hormonal factors as the key trigger for this growth so that

This paper investigates whether aid flows to developing countries fit well with their development priorities. In particular, we examine aid allocation across sectors in a given recipient country by using sectoral data on aid and indicators that measure the recipient's need for aid in each sector. The data show that inter-recipient aid allocation reflects the recipient's need. However, we found no evidence that inter-sectoral allocation fits with national priorities except in high- and middle-...

Baroletti, Steven; Bencivenga, Gina Ann; Gabardi, Steven

2004-06-01

To review the etiology, treatment, and preventive strategies of hyperuricemia and gout in kidney transplant recipients. Primary literature was obtained via Medline (1966-June 2003). Studies evaluating treatment and prevention of hyperuricemia and gout in kidney transplantation were considered for evaluation. English-language studies were selected for inclusion. Approximately 14,000 kidney transplantations were performed in the United States in 2003, and of those transplant recipients, nearly 13% will experience a new onset of gout. The prevalence of hyperuricemia is even greater. There are several mechanisms by which hyperuricemia and gout develop in kidney transplant recipients. Medication-induced hyperuricemia and renal dysfunction are 2 of the more common mechanisms. Prophylactic and treatment options include allopurinol, colchicine, corticosteroids, and, if absolutely necessary, nonsteroidal antiinflammatory drugs. It is generally recommended to decide whether the risks of prophylactic therapy and treatment outweigh the benefits. Often, the risk of adverse events associated with agents to treat these ailments tends to outweigh the benefits; therefore, treatment is usually reserved for symptomatic episodes of acute gout. Practitioners must also decide if changes in immunosuppressive regimens may be of benefit on a patient-by-patient basis.

Cerebral arteriography (CA) remains the gold standard in delineating both intra- and extracranial vascular anatomy. Most data relating to the safety of CA are drawn from studies of adult patients in whom the practicalities of the procedure, range of potential pathologies and comorbid factors are different from those in children. To evaluate the current local and neurological complication rates of paediatric CA in the setting of a tertiary level children's hospital in the UK. Data from patients who had undergone CA between January 1998 and July 2003 were reviewed. The medical, anaesthetic and nursing records, and angiography reports were reviewed for all identified patients. The following parameters were extracted and entered into a proforma: gender, age, ethnicity, diagnosis, cerebrovascular diagnosis, referral source, date of CA, number of vessels catheterized and local and neurological complications. A total of 176 CA studies were undertaken in 150 patients (median age 7.3 years, range neonate to 19 years; 83 males, 67 females) during the 5.5-year study period. The majority of referrals originated from the neurology (58%) and neurosurgery services (27.8%). No neurological complications or deaths occurred. Local complications occurred in eight children (4.5%). Five children had a groin haematoma and two had bleeding at the puncture site. A single child had a reduced pedal pulse distal to the site of catheterization, but Doppler imaging was normal. CA has a continuing role in the evaluation of cerebrovascular pathologies in children. Neurological complications are rare and local complications are not uncommon (around 5%), but are not usually serious. (orig.)

The number of neuroendovascular treatments of both ruptured and unruptured aneurysms has increased substantially in the last two decades. Complications of endovascular treatments of cerebral aneurysms are rare but can potentially lead to acute worsening of the neurological status, to new neurological deficits or death. Some of the possible complications, such as vascular access site complications or systemic side effects associated with contrast medium (e.g. contrast medium allergy, contrast induced nephropathy) can also be encountered in diagnostic angiography. The most common complications of endovascular treatment of cerebral aneurysms are related to acute thromboembolic events and perforation of the aneurysm. Overall, the reported rate of thromboembolic complications ranges between 4.7% and 12.5% while the rate of intraprocedural rupture of cerebral aneurysms is about 0.7% in patients with unruptured aneurysms and about 4.1% in patients with previously ruptured aneurysms. Thromboembolic and hemorrhagic complications may occur during different phases of endovascular procedures and are related to different technical, clinical and anatomic reasons. A thorough knowledge of the different aspects of these complications can reduce the risk of their occurrence and minimize their clinical sequelae. A deep understanding of complications and of their management is thus part of the best standard of care.

Oral piercings have a long history as part of religious, cultural, or sexual symbolism in many traditional tribes; currently, these ornaments have wide acceptance among young people. Several oral and systemic complications may be associated with this practice; however, limited data related to these complications can be obtained in the literature. This study includes 42 cases of oral piercings in 39 young adults, who were using or had used oral piercings, and the complications associated with their use. Immediate complications occurred in 29 cases, including excessive bleeding (69%) and pain (52.3%) as the most representative. Two cases of syncope were found. Late complications related to the piercing insertion site were observed in 97.6% of cases, with pain and swelling being present in 92.9% and 61.9% of cases, respectively. Dental pain and lacerations on the tongue represented the most prevalent complications associated with the surrounding tissues, accounting for 33.3% and 31% of cases. The use of oral piercings is related to a series of mainly local complications, and individuals who decide to use piercings should be aware of such complications. Individuals wishing to get a part of their body pierced should do so with qualified professionals and should regularly visit the dentist so that a regular control is achieved, thus ensuring the early detection of the adverse effects associated with this practice.

Lim, Ho Gon; Han, Sang Hoon [KAERI, Daejeon (Korea, Republic of)

2016-05-15

Since Fukushima accident, strong needs to estimate site risk has been increased to identify the possibility of re-occurrence of such a tremendous disaster and prevent such a disaster. Especially, in a site which has large fleet of nuclear power plants, reliable site risk assessment is very emergent to confirm the safety. In Korea, there are several nuclear power plant site which have more than 6 NPPs. In general, risk model of a NPP in terms of PSA is very complicated and furthermore, it is expected that the site risk model is more complex than that. In this paper, the method for constructing site risk model is proposed by using individual unit risk model. Procedure for the development of site damage (risk) model was proposed in the present paper. Since the site damage model is complicated in the sense of the scale of the system and dependency of the components of the system, conventional method may not be applicable in many side of the problem.

To evaluate a comprehensive magnetic resonance imaging (MRI) protocol as noninvasive diagnostic modality for simultaneous detection of parenchymal, biliary, and vascular complications after liver transplantation. Fifty-two liver transplant recipients suspected to have parenchymal, biliary, and (or) vascular complications underwent our MRI protocol at 1.5T unit using a phased array coil. After preliminary acquisition of axial T 1 w and T 2 w sequences, magnetic resonance cholangiography (MRC) was performed through a breath-hold, thin- and thick-slab, single-shot T 2 w sequence in the coronal plane. Contrast-enhanced magnetic resonance angiography (CEMRA) was obtained using a 3-dimensional coronal spoiled gradient-echo sequence, which enabled acquisition of 32 partitions 2.0 mm thick. A fixed dose of 20 ml gadobenate dimeglumine was administered at 2 mL/s. A post-contrast T 1 w sequence was also performed. Two observers in conference reviewed source images and 3-dimensional reconstructions to determine the presence of parenchymal, biliary, and vascular complications. MRI findings were correlated with surgery, endoscopic retrograde cholangiography (ERC), biopsy, digital subtraction angiography (DSA), and imaging follow-up. MRI revealed abnormal findings in 32 out of 52 patients (61%), including biliary complications (anastomotic and nonanastomotic strictures, and lithiasis) in 31, vascular disease (hepatic artery stenosis and thrombosis) in 9, and evidence of hepatic abscess and hematoma in 2. ERC confirmed findings of MRC in 30 cases, but suggested disease underestimation in 2. DSA confirmed 7 magnetic resonance angiogram (MRA) findings, but suggested disease overestimation in 2. MRI combined with MRC and CEMRA can provide a comprehensive assessment of parenchymal, biliary, and vascular complications in most recipients of liver transplantation. (author)

Sirolimus is an immunosuppressive agent increasingly used in cardiac transplant recipients in the setting of allograft vasculopathy or worsening renal function. Recently, sirolimus has been associated with increased risk of venous thromboembolism (VTE) in lung transplant recipients. To investigate whether this association is also present in cardiac transplant recipients, we retrospectively reviewed the charts of 67 cardiac transplant recipients whose immunosuppressive regimen included sirolimus and 134 matched cardiac transplant recipients whose regimen did not include sirolimus. Rates of VTE were compared. Multivariable Cox proportional hazards models tested the association of sirolimus use with VTE. A higher incidence of VTE was seen in patients treated with vs. without sirolimus (8/67 [12%] vs. 9/134 [7%], log-rank statistic: 4.66, p=0.03). Lower body mass index (BMI) and total cholesterol levels were also associated with VTE (p<0.05). The association of sirolimus with VTE persisted when adjusting for BMI (hazard ratio [95% confidence interval]: 2.96 [1.13, 7.75], p=0.03) but not when adjusting for total cholesterol (p=0.08). These data suggest that sirolimus is associated with an increased risk of VTE in cardiac transplant recipients, a risk possibly mediated through comorbid conditions. Larger, more conclusive studies are needed. Until such studies are completed, a heightened level of awareness for VTE in cardiac transplant recipients treated with sirolimus appears warranted. © 2012 John Wiley & Sons A/S.

Full Text Available Aim. The aim of this study was to define the role of preformed anti-HLA antibodies (anti-HLA in antibody-mediated rejection (AMR and cardiac allograft vasculopathy (CAV after heart transplantation. Materials and Methods. 140 heart transplant recipients were followed after heart transplantation performed for 106 dilated and 34 – ischemic cardiomyopathy. Anti-HLA was determined before transplantation by ELISA. Results. Recipients were divided into 2 groups: anti-HLA positive (n = 45, 32,1% and anti-HLA negative (n = 95, 67,9%. The incidence of AMR in anti-HLA positive group was 12 (26,67% and 11 (11,58% in anti-HLA negative group. Risk of AMR was significantly higher in anti-HLA positive recipients (RR 2,3: 95% CI 1,02–4,81, р = 0,03. During first three years after transplantation CAV was diagnosed in 9 (20% of anti-HLA positive recipients and in 7 (6,8% of patients without anti-HLA. (RR 2,7: 95% CI 1,08–6,82, р = 0,03. Survival in freedom from CAV in anti-HLA negative recipients was much higher than in anti-HLA positive recipients (0,89 ± 0,07, 0,72 ± 0,06, resp. (p = 0,02.Conclusions. The presence of preformed anti-HLA antibodies in candidates for heart transplantation increase the risk of AMR and CAV post transplantation in 2,3 and 2,7 times, respectively.

Full Text Available Reperfusion injury predisposes the kidney allograft to acute rejection. Apoptosis is a mechanism that results in graft injury, and TP53 is an important involved gene. To determine the association between single nucleotide polymorphism (SNP in the pro-apoptotic protein p53 (rs1625895 and acute rejection in renal transplants, we studied 100 recipients of kidney allografts and 100 healthy individuals served as controls. The polymorphism was determined by the polymerase chain reaction restriction-fragment length polymorphism (PCR-RFLP test. Overall, 31 recipients developed rejection. There was no difference in the genotype frequencies between the recipients and the controls. However, we found a difference of genotype and allele frequencies between recipients with and those without rejection. The WW genotype was more frequent in recipients with rejection. Although rejection is a complex immunologic event and functional importance of SNPs has not been confirmed yet, we suggest that wild type p53 may promote apoptosis during inflammation.

What can happen after lung transplantation and the importance of the time since transplantation: radiological review of post-transplantation complications.

Lung transplantation is the best treatment option in the final stages of diseases such as cystic fibrosis, pulmonary hypertension, chronic obstructive pulmonary disease, or idiopathic pulmonary fibrosis. Better surgical techniques and advances in immunosuppressor treatments have increased survival in lung transplant recipients, making longer follow-up necessary because complications can occur at any time after transplantation. For practical purposes, complications can be classified as early (those that normally occur within two months after transplantation), late (those that normally occur more than two months after transplantation), or time-independent (those that can occur at any time after transplantation). Many complications have nonspecific clinical and radiological manifestations, so the time factor is key to narrow the differential diagnosis. Imaging can guide interventional procedures and can detect complications early. This article aims to describe and illustrate the complications that can occur after lung transplantation from the clinical and radiological viewpoints so that they can be detected as early as possible.

To describe the pulmonary complications following hematopoietic stem cell transplantation (HSCT) that can present with a 'crazy-paving' pattern in high-resolution CT scans. Retrospective review of medical records from 2,537 patients who underwent HSCT. The 'crazy-paving' pattern consists of interlobular and intralobular septal thickening superimposed on an area of ground-glass attenuation on high-resolution CT scans. The CT scans were retrospectively reviewed by two radiologists, who reached final decisions by consensus. We identified 10 cases (2.02%), seven male and three female, with pulmonary complications following HSCT that presented with the 'crazy-paving' pattern. Seven (70%) patients had infectious pneumonia (adenovirus, herpes simplex, influenza virus, cytomegalovirus, respiratory syncytial virus, and toxoplasmosis), and three patients presented with non-infectious complications (idiopathic pneumonia syndrome and acute pulmonary edema). The 'crazy-paving' pattern was bilateral in all cases, with diffuse distribution in nine patients (90%), predominantly in the middle and inferior lung regions in seven patients (70%), and involving the anterior and posterior regions of the lungs in nine patients (90%). The 'crazy-paving' pattern is rare in HSCT recipients with pulmonary complications and is associated with infectious complications more commonly than non-infectious conditions

There is a consensus that portal venous pressure (PVP) modulation prevents portal hypertension (PHT) and consequent complications after adult living donor liver transplantation (ALDLT). However, PVP-modulation strategies need updating based on most recent findings. We examined our 10-year experience of PVP modulation and reevaluate whether it is necessary for all recipients or selected recipients in ALDLT. In this retrospective study, 319 patients who underwent ALDLT from 2007 to 2016 were divided into three groups according to the necessity and results of PVP modulation: not indicated (n=189), indicated and successful (n=92), and indicated but failed (n=38). Graft survival and associations with various clinical factors were investigated. PVP modulation was performed mainly by splenectomy to lower final PVP to ≤15 mmHg. Successful PVP modulation improved prognosis that was equivalent to that of patients who did not need modulation, whereas failed modulation was associated with increased incidence of small-for-size syndrome (SFSS) (p=0.003), and early graft loss (EGL) (p=0.006). Among patients with failed modulation, donor age ≥45 years (hazard ratio [HR], 3.67; p=0.02) and ABO incompatibility (HR, 3.90; p=0.01) were independent risk factors for graft loss. Survival analysis showed that PVP >15 mmHg was related to poor prognosis in grafts from either ABO-incompatible or older donor aged ≥45 years (pmodulation is not necessarily required in all recipients. While grafts from both ABO-compatible/identical and young donor can tolerate PHT, lowering PVP to ≤15 mmHg is a key to preventing SFSS and consequent EGL with grafts from either ABO-incompatible or older donors.

Acute cellular rejection (ACR), a reversible process, can affect the graft survival. To evaluate the relation between ACR and clinical factors in recipients of allograft liver transplantation. 47 recipients of liver were consecutively enrolled in a retrospective study. Their information were retrieved from their medical records and analyzed. Of the 47 recipients, 38 (81%) experienced acute rejection during 24 months of the transplantation. None of the studied factors for occurring transplant rejection, i.e ., blood groups, sex, age, familial history of disease, receiving drugs and blood products, type of donor, Child score, and Child class, was not found to be significant. During a limited follow-up period, we did not find any association between ACR and suspected risk factors.

Skin squamous-cell-carcinoma (SCC), is the main complication in long-term kidney-transplant recipients, and it can include donor-derived cells. Preclinical models demonstrated the involvement of epithelial mesenchymal transition (EMT) in the progression of skin SCC, and the role of Snail, an EMT transcription factor, in cancer stem-cell survival and expansion.Here, we studied stem-cells and EMT expression in SCCs and concomitant actinic keratoses (AK) in kidney-transplant recipients. In SCC and AK in 3 female recipients of male kidney-transplants, donor-derived Y chromosome in epidermal stem cells was assessed using combined XY-FISH/CD133 immunostaining, and digital-droplet-PCR on laser-microdissected CD133 expressing epidermal cells.For EMT study, double immunostainings of CD133 with vimentin or snail and slug, electron microscopy and immunostainings of keratinocytes junctions were performed. Digital droplet PCR was used to check CDH1 (E-cadherin) expression level in laser-microdissected cells co-expressing CD133 and vimentin or snail and slug.The numbers of Y-chromosome were assessed using digital droplet PCR in laser-microdissected cells co-expressing CD133 and vimentin, or snail and slug, and in CD133 positive cells not expressing any EMT maker. We identified donor-derived stem-cells in basal layers and invasive areas in all skin SCCs and in concomitant AKs, but not in surrounding normal skin.The donor-derived stem-cells expressed the EMT markers, vimentin, snail and slug in SCCs but not in AKs. The expression of the EMT transcription factor, SNAI1, was higher in stem-cells when they expressed vimentin. They were located in invasive areas of SCCs. In these areas, the expressions of claudin-1 and desmoglein 1 were reduced or absent, and within the basal layer there were features of basal membrane disappearance.Donor-derived stem cells were in larger numbers in stem cells co-expressing vimentin or snail and slug than in stem cells not expressing any EMT marker

To evaluate the postoperative CT appearance, complications and potential pitfalls of radical cystectomy with orthotopic neobladder reconstruction. We examined 46 patients [43 men and 3 women aged 34-72 (mean, 56.7) years] who had undergone neobladder reconstruction (ileocolic neobladder in 25 patients and ileal-W neobladder in 21). The CT scans were assessed in terms of their depiction of normal anatomy, namely the shape, location and internal architecture of the neobladder, the location of bladder bases, and the ureteral course. Early and late complications were also assessed. The characteristics of ileocolic neobadder were a right-side location, a lobulated outer margin, interal projections due to haustra or plication, a base in the retropubis, and right-side insertion of both ureters. In contrast, the characteristics of an ileal-W neobladder were a central location, an ovoid shape, nodular thickening at the ureteral insertion site, internal projections due to plication, and a retropubic bladder base. Early complications included hematoma with abscess formation (n=2), and postoperative peritonitis (n=1), while late complications were hydronephrosis due to stricture ar the ureteral anastomotic site (n=16), tumor recurrence at this site (n=1), distal ureteral stone (n=1), mucus urinary retention (n=1), incisional hernia (n=2), tumor recurrence in the pelvic side wall (n=1), carcinomatosis peritonei (n=1), and liver metastasis (n=2). A knowledge of normal anatomic changes is essential for the accurate interpretation of CT scans. CT is a useful modality of the evaluation of postoperative change and the complications occurring in patients who have undergone radial cystectomy with othotopic neobladder reconstruction.

Full Text Available Background. We evaluated patient characteristics of live donor liver transplant (LDLT recipients undergoing a fast-track protocol without intensive care unit (ICU admission versus LDLT patients receiving posttransplant ICU care. Methods. Of the 153 LDLT recipients, 46 patients were included in our fast-track protocol without ICU admission. Both, fast-tracked patients and ICU-admitted patients were compared regarding donor and patient characteristics, perioperative characteristics, and postoperative outcomes and complications. In a subgroup analysis, we compared fast-tracked patients with patients who were admitted in the ICU for less than 24 hours. Results. Fast-tracked versus ICU patients had a lower model for end-stage liver disease score (13 ± 4 vs 18 ± 7; P < 0.0001, lower preoperative bilirubin levels (51 ± 50 μmol/L vs 119.4 ± 137.3 μmol/L; P < 0.001, required fewer units of packed red blood cells (1.7 ± 1.78 vs 4.4 ± 4; P < 0.0001, and less fresh-frozen plasma (2.7 ± 2 vs 5.8 ± 5; P < 0.0001 during transplantation. Regarding postoperative outcomes, fast-tracked patients presented fewer bacterial infections within 30 days (6.5% [3] vs 29% [28]; P = 0.002, no episodes of pneumonia (0% vs 11.3% [11]; P = 0.02, and less biliary complications within the first year (6% [3] vs 26% [25]; P = 0.001. Also, fast-tracked patients had a shorter posttransplant hospital stay (10.8 ± 5 vs 21.3 ± 29; P = 0.002. In the subgroup analysis, fast-tracked vs ICU patients admitted for less than 24 hours had lower requirements of packed red blood cells (1.7 ± 1.78 vs 3.9 ± 4; P = 0.001 and fresh-frozen plasma (2.7 ± 2 vs 5.8 ± 4.5; P = 0.0001. Conclusions. Fast-track of selected patients after LDLT is safe and feasible. An objective score to perioperatively select LDLT recipients amenable to fast track is yet to be determined.

Full Text Available Background & objectives: Diarrhoea is the main clinical manifestation caused by intestinal parasitic infections in patients, with special reference to transplant recipients who require careful consideration to reduce morbidity and mortality. Further, molecular characterization of some important parasites is necessary to delineate the different modes of transmission to consider appropriate management strategies. We undertook this study to investigate the intestinal parasitic infections in transplant recipients with or without diarrhoea, and the genotypes of the isolated parasites were also determined. Methods: Stool samples from 38 transplant recipients comprising 29 post-renal, two liver and seven bone marrow transplant (BMT recipients presenting with diarrhoea and 50 transplant recipients (42 post-renal transplant, eight BMT without diarrhoea were examined for the presence of intestinal parasites by light microscopy using wet mount, modified Ziehl-Neelsen staining for intestinal coccidia and modified trichrome staining for microsporidia. Genotypes of Cryptosporidium species were determined by multilocus genotyping using small subunit ribosomal (SSUrRNA, Cryptosporidium oocyst wall protein (COWP and dihydrofolate reductase (DHFR as the target genes. Assemblage study for Giardia lamblia was performed using triose phosphate isomerase (TPI as the target gene. Samples were also screened for bacterial, fungal and viral pathogens. Results: The parasites that were detected included Cryptosporidium species (21%, 8/38, Cystoisospora (Isospora belli (8%, 3, Cyclospora cayetanensis (5%, 2, G. lamblia (11%, 4, Hymenolepis nana (11%, 4, Strongyloides stercoralis (3%, 1 and Blastocystis hominis (3%, 1. Multilocus genotyping of Cryptosporidium species at SSUrRNA, COWP and DHFR loci could detect four isolates of C. hominis; two of C. parvum, one of mixed genotype and one could not be genotyped. All the C. hominis isolates were detected in adult post

Natural killer (NK) cells are reported to have an important role in the resistance of lethally irradiated recipients to bone marrow transplantation (BMT). Therefore, we investigated the effects of recipient NK depletion on survival, chimerism, and hematopoietic reconstitution after lethal irradiation and the transplantation of limiting amounts of T-cell-deficient bone marrow (BM). When administered before BMT, anti-asialo GM1 (ASGM1) antiserum treatment, effective in depleting in vivo NK activity, was associated with a marked increase in survival in 3 of 3 allogeneic combinations (BALB/c into C3H/HeN, C57B1/6, or C3B6F1). This enhanced survival was independent of the susceptibility of each recipient strain to accept BALB/c BM. Moreover, recipient anti-ASGM1 treatment was also effective in increasing survival in recipients of syngeneic BM, suggesting that NK cells can adversely affect engraftment independent of genetically controlled polymorphic cell surface determinants. Analysis of chimerism in surviving animals 2 months post-BMT showed that recipient NK depletion significantly increased the level of donor engraftment when high doses of BM were transplanted. These studies also demonstrated that anti-ASGM1 pretreatment mainly resulted in an increase in extramedullary hematopoiesis in the second and third week after irradiation. Anti-ASGM1 treatment also dramatically accelerated the rate of appearance of donor-derived cells with a higher level of donor-cell engraftment apparent at a time when the differences in survival between NK-depleted and control BMT recipients became significant. Peripheral cell counts were also affected by NK depletion, with significantly enhanced platelet and red blood cell recovery and a moderate increase in granulocyte recovery

Bémeur, Chantal; Butterworth, Roger F

Malnutrition is a common feature of chronic liver diseases that is often associated with a poor prognosis including worsening of clinical outcome, neuropsychiatric complications as well as outcome following liver transplantation. Nutritional assessment in patients with cirrhosis is challenging owing to confounding factors related to liver failure. The objectives of nutritional intervention in cirrhotic patients are the support of liver regeneration, the prevention or correction of specific nutritional deficiencies and the prevention and/or treatment of the complications of liver disease per se and of liver transplantation. Nutritional recommendations target the optimal supply of adequate substrates related to requirements linked to energy, protein, carbohydrates, lipids, vitamins and minerals. Some issues relating to malnutrition in chronic liver disease remain to be addressed including the development of an appropriate well-validated nutritional assessment tool, the identification of mechanistic targets or therapy for sarcopenia, the development of nutritional recommendations for obese cirrhotic patients and liver-transplant recipients and the elucidation of the roles of vitamin A hepatotoxicity, as well as the impact of deficiencies in riboflavin and zinc on clinical outcomes. Early identification and treatment of malnutrition in chronic liver disease has the potential to lead to better disease outcome as well as prevention of the complications of chronic liver disease and improved transplant outcomes.

There is a paucity of data regarding the complications in kidney transplant patients who may require intensive care unit (ICU) management, despite being the most common solid organ transplant worldwide. To identify the main reasons for ICU admission and to determine the factors associated with hospital mortality in kidney transplant recipients. This single-center retrospective cohort study was conducted between September 2013 and June 2014, including all consecutive kidney transplant patients requiring ICU admission. We collected data on patient demographics, transplant characteristics, clinical data, and prognostic scores. The independent determinants of hospital mortality were identified by multiple logistic regression analysis. We also assessed the performance of Simplified Acute Physiology Score 3 (SAPS 3) and Acute Physiology and Chronic Health Evaluation II (APACHE II) scores. We analyzed data from 413 patients, the majority of whom were admitted late after renal transplantation (1169 days; 63-3003 days). The main reason for admission was sepsis (33.2%), followed by cardiovascular disease (16%). Age (odds ratio [OR] 1.05, confidence interval [CI], 1.01-1.09), SAPS 3 score (OR 1.04, CI, 1.01-1.08), the need for mechanical ventilation (OR 26.47, CI, 10.30-68.08), and vasopressor use (OR 3.34, CI, 1.37-8.13) were independently associated with hospital mortality. The performance of SAPS 3 and APACHE II scores was poor in this population and overestimated the mortality rates. Sepsis was the main reason for ICU admission in kidney transplant recipients, followed by cardiovascular disease. Age and disease severity were associated with hospital mortality.

Mucormycosis in a Renal Transplant Recipient: Case Report and Comprehensive Review of Literature

Tamim Hamdi

2014-01-01

Full Text Available Mucormycosis is a rare but devastating infection. We present a case of fatal disseminated mucormycosis infection in a renal transplant patient. Uncontrolled diabetes mellitus and immunosuppression are the major predisposing factors to infection with Mucorales. Mucorales are angioinvasive and can infect any organ system. Lungs are the predominant site of infection in solid organ transplant recipients. Prompt diagnosis is challenging and influences outcome. Treatment involves a combination of surgical and medical therapies. Amphotericin B remains the cornerstone in the medical management of mucormycosis, although other agents have been used. Newer agents are promising.

A recent randomized trial demonstrated that 1 year of antiviral prophylaxis for cytomegalovirus (CMV) after lung transplantation is superior to 3 months of treatment for prevention of CMV disease. However, it is uncertain if a shorter duration of prophylaxis might result in a similar rate of CMV disease among select lung transplant (LT) recipients who are at lower risk for CMV disease, based on baseline donor (D) and recipient (R) CMV serologies. We retrospectively assessed incidence, cumulative probability, and predictors of CMV disease and viremia in LT recipients transplanted between July 2004 and December 2009 at our center, where antiviral CMV prophylaxis for 6-12 months is standard. Of 129 LT recipients, 94 were at risk for CMV infection based on donor CMV seropositivity (D+) or recipient seropositivity (R+); 14 developed CMV disease (14.9%): 11 with CMV syndrome, 2 with pneumonitis, and 1 with gastrointestinal disease by the end of follow-up (October 2010); 17 developed asymptomatic CMV viremia (18.1%). The cumulative probability of CMV disease was 17.4% 18 months after transplantation. CMV D+/R- recipients who routinely received 1 year of prophylaxis were more likely to develop CMV disease compared with D+/R+ or D-/R+ recipients, who routinely received 6 months of prophylaxis (12/45 vs. 2/25 vs. 0/24, P = 0.005). Recipients who stopped CMV prophylaxis before 12 months (in D+/R- recipients) and 6 months (in R+ recipients) tended to develop CMV disease more than those who did not (9/39 vs. 3/41, P = 0.06). On a 6-month CMV prophylaxis protocol, few R+ recipients developed CMV disease in this cohort. In contrast, despite a 12-month prophylaxis protocol, D+/R- LT recipients remained at highest risk for CMV disease. © 2012 John Wiley & Sons A/S.

Bacterial infections remain a challenge to solid organ transplantation. Due to the alarming spread of carbapenem-resistant gram negative bacteria, these organisms have been frequently recognized as cause of severe infections in solid organ transplant recipients. Between 15 May and 30 September 2012 we enrolled 887 solid organ transplant recipients in Italy with the aim to describe the epidemiology of gram negative bacteria spreading, to explore potential risk factors and to assess the effect of early isolation of gram negative bacteria on recipients' mortality during the first 90 days after transplantation. During the study period 185 clinical isolates of gram negative bacteria were reported, for an incidence of 2.39 per 1000 recipient-days. Positive cultures for gram negative bacteria occurred early after transplantation (median time 26 days; incidence rate 4.33, 1.67 and 1.14 per 1,000 recipient-days in the first, second and third month after SOT, respectively). Forty-nine of these clinical isolates were due to carbapenem-resistant gram negative bacteria (26.5%; incidence 0.63 per 1000 recipient-days). Carbapenems resistance was particularly frequent among Klebsiella spp. isolates (49.1%). Recipients with longer hospital stay and those who received either heart or lung graft were at the highest risk of testing positive for any gram negative bacteria. Moreover recipients with longer hospital stay, lung recipients and those admitted to hospital for more than 48h before transplantation had the highest probability to have culture(s) positive for carbapenem-resistant gram negative bacteria. Forty-four organ recipients died (0.57 per 1000 recipient-days) during the study period. Recipients with at least one positive culture for carbapenem-resistant gram negative bacteria had a 10.23-fold higher mortality rate than those who did not. The isolation of gram-negative bacteria is most frequent among recipient with hospital stays >48 hours prior to transplant and in those

Forty-four organ recipients died (0.57 per 1000 recipient-days during the study period. Recipients with at least one positive culture for carbapenem-resistant gram negative bacteria had a 10.23-fold higher mortality rate than those who did not.The isolation of gram-negative bacteria is most frequent among recipient with hospital stays >48 hours prior to transplant

Lactobacillus rhamnosus is a rare clinical pathogen. A case of bacteremia caused by L. rhamnosus in a kidney transplant recipient is described. Once considered only as a contaminant or a low-virulence organism, L. rhamnosus might be an opportunistic pathogen in immunocompromised patients. To our knowledge, this is the first report of primary bloodstream infection caused by L. rhamnosus in a kidney transplant recipient. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The routine dental practice involves various dental procedures which needs the application of local anesthetics. Generally, there are very few complications associated with these procedures. Complications such as tissue necrosis can occur following the rapid injection of local anesthetic solutions. Palate is a favorable site for soft tissue lesions, various factors such as direct effects of the drug, blanching of the tissues during injection, a relatively poor blood supply, and reactivation of the latent forms of herpes can all promote to tissue ischemia and a lesion in the palate.

Different publications show an increased incidence of neoplasms in renal transplant patients. The objective of this study is to determine the incidence of cancer in the recipients of renal transplants performed in the A Coruña Hospital (Spain) during the period 1981–2007. During the study period 1967 kidney transplants were performed, corresponding to 1710 patients. Patients with neoplasms prior to the transplant will be excluded (n = 38). A follow-up study was carried out in order to estimate cancer incidence after transplantation. For each patient, information included donor and recipient characteristics, patients and graft survival and cancer incidence after transplantation. Incident cancer is considered as new cases of cancer after the transplant with anatomopathological confirmation. Their location will be classified according to the ICD-9. The analysis will be calculated using the indirect standardisation method. Age-adjusted cancer incidence rates in the Spanish general population will be obtained from the Carlos III Health Institute, the National Epidemiology Centre of the Ministry of Science and Technology. Crude first, second and third-year post-transplantation cancer incidence rates will be calculated for male and female recipients. The number of cases of cancer at each site will be calculated from data in the clinical records. The expected number of cancers will be calculated from data supplied by the Carlos III Health Institute. For each tumour location we will estimate the standardized incidence ratios (SIRs), using sex-specific cancer incidence rates, by dividing the incidence rate for the transplant patients by the rate of the general population. The 95% confidence intervals of the SIRs and their associated p-values will be calculated by assuming that the observed cancers follow a Poisson distribution. Stratified analysis will be performed to examine the variation in the SIRs with sex and length of follow-up. Competing risk survival analysis

Dyslipidemia is common in liver transplant recipients. This retrospective study investigates whether donors play a role. Prospectively collected data of donors and recipients of deceased-donor liver transplantation (DDLT) and living-donor liver transplantation (LDLT) were reviewed. Total cholesterol, triglyceride, low-density lipoprotein, high-density lipoprotein (HDL) and fasting glucose were compared between groups. HDL ≥1.6 mmol/L at 2 years after transplant was considered the marker of a favorable post-transplant lipid profile in recipients. Univariate and multivariate analyses were performed to identify predictive factors for this marker. There were 85 DDLTs and 80 LDLTs. LDLT donors were younger (30 vs. 50 years, p index (21.2 vs. 23.7, p glucose (4.85 vs. 7.21 mmol/L, p triglyceride (0.87 vs. 1.22 mmol/L, p = 0.016) but higher HDL (1.58 vs. 1.39 mmol/L, p = 0.022). LDLT recipients also had higher HDL at 1 year (1.48 vs. 1.28 mmol/L, p = 0.026) and 2 years (1.43 vs. 1.21 mmol/L, p = 0.008). Fourteen (16.5%) DDLT recipients and 27 (33.8%) LDLT recipients had HDL ≥1.6 mmol/L at 2 years. On multivariate analysis, donor HDL ≥1.6 mmol/L (RR 4.311, 95% CI 1.666-11.158, p = 0.003) and recipient body mass index <24 (RR 2.753, 95% CI 1.064-7.127, p = 0.037) were the two independent predictive factors. LDLT recipients had better lipid profiles than DDLT recipients. The feature of high HDL level in donors was transferred to recipients.

Full Text Available Human cytomegalovirus is a ubiquitous herpesvirus that establishes lifelong latency after primary infection, but can cause life-threatening disease in immunosuppressed patients. CMV invasive disease leads to significant morbidity and mortality following kidney transplantation. We tested 2 groups of patients - Group A included 20 potential kidney recipients and 29 potential donors investigated by ELISA and Group B included 53 adult kidney transplant recipients all of them tested in ELISA and 24 of them tested in QRT-PCR for CMV-DNA from plasma samples. In group A 16 (80% of 20 potential kidney recipients were anti-CMV IgG positive and 4 (20% were anti-CMV IgG negative. Twenty eight of 29 potential donors were found seropositive, and only one was not infected. In group B overall 119 ELISA tests for specific anti-CMV antibodies were performed. Anti-CMV IgM negative was 68 (57% of the tested samples, twelve (10% showed anti-CMV IgM equivocal results and 39 samples (33% were with anti-CMV IgM positive. Seven of them (13,2% showed repeatedly anti CMV IgM positive results. All 119 (100% displayed аnti-CMV IgG positive results. Overall 41 PCR analyses from plasma samples of 24 kidney transplant recipients (group B were performed. CMV-DNA replication was detected in 5 plasma samples obtained from 3 patients (12.5% at a different time - from 20 days till almost 8 years after the transplantation. Despite the high seroprevalence to CMV 20% of the potential recipients were at high risk of primary infection when receiving a kidney from a seropositive donor. Positive serological results during the regular post-transplantation monitoring complemented with or without clinical data are indicative and require further QRT-PCR analysis.

Across pediatric organ transplant populations, patient and family psychosocial functioning is associated with important health-related outcomes. Research has suggested that pediatric heart transplant recipients and their families are at increased risk for adverse psychosocial outcomes; however, recent investigation of psychosocial functioning in this population is lacking. This study aimed to provide a contemporary characterization of psychosocial functioning in pediatric heart transplant recipients and their families. Associations between psychosocial function, demographic variables, and transplant-related variables were investigated. Fifty-six parents/guardians of pediatric heart transplant recipients completed a comprehensive psychosocial screening measure during transplant follow-up clinic visits. Descriptive statistics, correlational analyses, and independent samples t tests were performed. Forty percent of pediatric heart transplant recipients and their families endorsed clinically meaningful levels of total psychosocial risk. One-third of patients presented with clinically significant psychological problems per parent report. Psychosocial risk was unassociated with demographic or transplant-related factors. Despite notable improvements in the survival of pediatric heart transplant recipients over the past decade, patients and families present with sustained psychosocial risks well beyond the immediate post-transplant period, necessitating mental health intervention to mitigate adverse impact on health-related outcomes. © 2018 John Wiley & Sons A/S.

Several recipient vessels can be used in free microsurgical fibula flaps (MFFs) for the treatment of avascular necrosis of the femoral head (ANFH). Few articles investigate the influence of different recipient vessels on outcomes of MFF for ANFH. A comprehensive literature search of databases including PubMed-Medline, Ovid-Embase, and Cochrane Library was performed to collect the related studies. The Medical Subject Headings used were "femur head necrosis" and "bone transplantation." The relevant words in title or abstract included but not limited to "fibula flap," "fibular flap," "vascularized fibula," "vascularized fibular," "free fibula," "free fibular," "femoral head necrosis," "avascular necrosis of femoral head," and "ischemic necrosis of femoral head." The methodological index for nonrandomized studies was adopted for assessing the studies included in this review. Finally, 15 studies encompassing a total of 1267 patients (1603 hips) with ANFH were pooled in the overall analysis. Recipient vessels for MFF included the ascending branch of the lateral circumflex femoral artery and vein in 8 studies, descending branch of the lateral circumflex femoral artery and vein in 2 studies, second perforating branch of the deep femoral artery and vein in 4 studies, and inferior gluteal artery and vein in 1 study. Preoperative and postoperative average Harris hip score and pooled analyses of the rate of conversion, radiographic progression, and hip surgery-related complications showed no significant difference on the outcomes of MFF on ANFH between using different recipient vessels. Different recipient vessels did not affect outcomes in MFF procedures for ANFH. High-quality randomized controlled trials and prospective studies would be necessary to clarify reliable advantages and disadvantages between different recipient vessels. Until then, surgeons are justified in using ascending branch of the lateral circumflex femoral artery and vein, descending branch of the lateral

Potential ecosystem effects caused by the effluent cooling water from the Simpevarp nuclear power plant, close to Oskarshamn on the Swedish coast of the Baltic Proper, are monitored in yearly surveys using gillnets and fyke nets. Fishing is undertaken at several sites in a coastal gradient starting at the location of the emitted cooling water, and in a reference area 100 km north of the recipient. Soft bottom macro fauna and macro vegetation are monitored both in the gradient and in the reference area. Fish mortality due to entrapment in the cooling water system and commercial landings are monitored to assess the effects on the local fishery. The water used for cooling is normally heated by 10-12 deg C when passing through the power plant. In sheltered parts of the recipient bay of Hamnefjaerden, the surface water was 4-6 deg C warmer in April-November 2011 than in the reference area comparable reference areas and the emitted water occasionally exceeded 30 deg C in the summer. Fish losses in the cooling water rinsing system were dominated by Baltic herring. Effects on abundances at the population level are estimated to be small, but local effects cannot be ruled out. Perch (Perca fluviatilis), roach (Rutilus rutilus) and silver bream (Blicca bjoerkna) dominated the catches in the surveys with gillnets in Hamnefjaerden, as well as in the archipelago surrounding the power plant. Perch abundances increased in these areas. Catches of roach decreased close to the power plant, but also in the reference area. Perch in the gillnet catches were younger and grew faster close to the power plant than in the reference area. Abnormal gonads, previously observed at high frequencies in perch and roach in Hamnefjaerden, were rare in the 2011 sampling. The abundance of young of the year perch in the recipient did not change over time. The size of the perch fry however, increased in Hamnefjaerden, as well as in the local reference area.

Full Text Available Abstract Background In kidney transplant (Kt recipients , hypertension is a major risk for cardiovascular complications but also for graft failure. Blood pressure (BP control is therefore mandatory. Office BP (OBP remains frequently used for clinical decisions, however home BP (HBP have brought a significant improvement in the BP control. Sodium is a modifiable risk factor, many studies accounted for a decrease of BP with a sodium restricted diet. Increased potassium intake has been also recommended in hypertension management. Using an agreement between office and home BP, the present study investigated the relations between the BP control in Kt recipients and their urinary excretion and dietary consumption of sodium and potassium. Methods The BP control defined by OBP 30. Results Using an agreement between OBP and HBP, we identified controlled (21% and uncontrolled recipients (49%. Major confounding effects susceptible to interfere with the BP regulation did not differ between groups, the amounts of sodium excretion were similar (154 ± 93 vs 162 ± 88 mmol/24 h but uncontrolled patients excreted less potassium (68 ± 14 vs 54 ± 20 mmol/24 h; P = 0.029 and had significantly lower potassium intakes (3279 ± 753 vs 2208 ± 720 mg/24 h; P = 0.009, associated with a higher urinary Na+/K + ratio. Systolic HBP was inversely and significantly correlated to urinary potassium (r = −0.48; P = 0.002, a positive but non significant relation was observed with urinary sodium (r = 0,30;P = 0.074. Conclusions Half of the treated hypertensive Kt recipients remained uncontrolled in office and at home. Restoring a well-balanced sodium/potassium ratio intakes could be a non pharmacological opportunity to improve blood pressure control.

Arthroscopic reconstruction of the anterior cruciate ligament (ACL) using autografts or allografts is being performed with increasing frequency, particularly in young athletes. Although the procedure is generally well tolerated, with good success rates, early and late complications have been documented. As clinical manifestations of graft complications are often non-specific and plain radiographs cannot directly visualize the graft and the adjacent soft tissues, MR imaging has a definite role in the diagnosis of complications after ACL reconstruction and may direct subsequent therapeutic management. Our purpose is to review the normal MR imaging of the ACL graft and present the MR imaging findings of a wide spectrum of complications after ACL reconstruction, such as graft impingement, graft rupture, cystic degeneration of the graft, postoperative infection of the knee, diffuse and localized (i.e., cyclops lesion) arthrofibrosis, and associated donor site abnormalities. Awareness of the MR imaging findings of complications as well as the normal appearances of the normal ACL graft is essential for correct interpretation. (orig.)

2018-01-02

BK polyomavirus (BKV) is an opportunist agent associated with nephropathy (BKVAN) in 1-10% of kidney transplant recipients. BKV is classified into genotypes or subgroups according to minor nucleotidic variations with unknown biological implications. Studies assessing the possible association between genotypes and the risk of BKVAN in kidney transplant patients have presented conflicting results. In these studies, genotype Ia, which is highly prevalent in Brazil, was less frequently found and, thus, comparative data on the biological properties of this genotype are lacking. In this study, BKV Ia and Ib1 genotypes were compared according to their viral load, genetic evolution (VP1 and NCCR) - in a cohort of renal transplant recipients. The patients infected with Ia (13/23; 56.5%) genotype exhibited higher viral loads in urine [>1.4 log over Ib1 (10/23; 43.5%); p=0.025]. In addition, genotype Ia was associated with diverse mutations at VP1 loops and sites under positive selection outside loops, which were totally absent in Ib1. Although the number of viremic patients was similar, the three patients who had BK nephropathy (BKVAN) were infected with Ia genotype. NCCR architecture (ww or rr) were not distinctive between Ia and Ib1 genotypes. Ia genotype, which is rare in other published BKV cohorts, presented some diverse biological properties in transplanted recipients in comparison to Ib1. Copyright © 2017 Elsevier B.V.

Better control of blood sugar and reduction of diabetes complications through insulin therapy could convince people to choose this method. However, patients might refuse insulin therapy due to its painful injection, limitations in daily activities, and hypoglycemia. Thus, insulin therapy could have both positive and negative effects on patients' quality of life (QOL). Therefore, the aim of this study was to compare the QOL of insulin recipient and insulin refusal patients with type 2 diabetes. This study was a descriptive and comparative research conducted on 126 patients; 63 were insulin recipients and 63 had refused insulin therapy. Participants were under the care of the Endocrine and Metabolism Research Center of Isfahan, Iran. Data were gathered using the Diabetes Quality of Life (DQOL) questionnaire. In this tool, higher scores indicated lower QOL in patients. Data were analyzed using independent t-test, analysis of covariance, Mann-Whitney, Chi-square, and Pearson and Spearman's correlation. There was a significant difference (P refusal patients (mean = 1.74, SD = 0.41) in terms of mean QOL score. In addition, men and participants with higher educational levels reported a better QOL (P refusal patients had a better QOL. It seems that QOL is associated with the acceptance or refusal of insulin therapy. Therefore, enhancement of QOL could be related to all aspects of the disease, especially its treatment method and solving the therapeutic problems.

Full Text Available Donation after cardiac death (DCD has expanded in the last decade in the US; however, DCD liver utilization has flattened in recent years due to poor outcomes. We examined clinical and quality of life (QOL outcomes of DCD recipients by conducting a retrospective and cross-sectional review of patients from 2003 to 2010. We compared clinical outcomes of DCD recipients (n=60 to those of donation after brain death (DBD liver recipients (n=669 during the same time period. DCD recipients had significantly lower rates of 5-year graft survival (P<0.001 and a trend toward lower rates of 5-year patient survival (P=0.064 when compared to the DBD cohort. In order to examine QOL outcomes in our cohorts, we administered the Short Form Liver Disease Quality of Life questionnaire to 30 DCD and 60 DBD recipients. The DCD recipients reported lower generic and liver-specific QOL. We further stratified the DCD cohort by the presence of ischemic cholangiopathy (IC. Patients with IC reported lower QOL when compared to DBD recipients and those DCD recipients without IC (P<0.05. While the results are consistent with clinical experience, this is the first report of QOL in DCD recipients using standardized measures. These data can be used to guide future comparative effectiveness studies.

Rhabdomyolysis is a pathological syndrome caused by skeletal muscle cell damage that affects the integrity of the cellular membrane and leads to the release of toxic intracellular constituents into the bloodstream. Although cytomegalovirus (CMV) has rarely been reported as a cause of rhabdomyolysis, CMV infection could be considered as a possible cause because of its clinical significance in kidney transplant recipients (KTRs). We report 2 cases of rhabdomyolysis associated with CMV infection in KTRs. A 64-year-old woman (Case 1) and a 65-year-old man (Case 2), who had each received a kidney from a living unrelated donor, were admitted with complaints of weakness in both legs and myalgia. Laboratory findings revealed highly increased creatine phosphokinase and myoglobinuria. In both cases, no recent alterations of medications had occurred, and other causes of rhabdomyolysis--such as trauma, alcohol, drugs, and electrolyte abnormalities - were excluded. CMV pp65 antigen was positive, and patients were diagnosed with rhabdomyolysis associated with CMV infection. Both patients recovered without complications after ganciclovir treatment. In conclusion, CMV infection should be considered as a possible cause of rhabdomyolysis in KTRs. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Full Text Available Introduction: Endocrine complications are common after hematopoietic stem cell transplant (HSCT. Although HSCT is performed at various centers in India, no study is available for endocrine dysfunctions among them. This study was carried out with the objective to evaluate endocrine dysfunction among patients undergone HSCT in the past. Materials and Methods: We carried out a cross-sectional study in a 50 post-HSCT recipients (39 allogenic, 11 autologous. All relevant data were collected from patient′s records. Samples for hormonal estimation were collected and stimulation tests for cortisol and growth hormone were interpreted based on peak values achieved during insulin tolerance test. Results: The mean age of patients was 26.3 ± 16.9 years (range 4-74. Adrenal insufficiency (AI was present in 60%, hypergonadotropic hypogonadism (HH in 60%, growth hormone deficiency (GHD in 54%, hypothyroidism in 4%, hyperprolactinemia in 4%, new onset diabetes after transplant in 4%, and impaired fasting glucose in 6%. Multiple endocrine complications were common. GHD was present in 77% of children (n = 22 although height standard deviation score was not statistically different compared to those who didn′t have GHD. HH was present in 36% of children. In adults (n = 28, 36% had GHD, all females had HH, and 89% of males had HH. Germ cell dysfunction with compensated Leydig cell dysfunction was the most common pattern of HH in males. Fifteen patients had graft versus host disease (GVHD. GVHD had no bearing on development of endocrine deficiencies. AI was related to duration after and type of transplant, but was unrelated to steroid intake. Conclusions: Endocrine manifestations are common after HSCT; they can occur as early or late complications. All HSCT recipients should have endocrine evaluation as per prevailing guidelines.

Fever, skin rash, headache, and thrombocytopenia are considered hallmarks of dengue infection. However, these symptoms are frequently observed in infectious and non-infectious complications of hematopoietic stem cell transplant recipients and oncohematological patients. Thus, laboratory confirmation of dengue is relevant for prompt intervention and proper management of dengue in endemic and non-endemic regions. Because no prospective study of dengue has been conducted in these populations, the actual morbidity and mortality of dengue is unknown. In the present series, we describe five cases of dengue in patients living in endemic areas, emphasizing the prolonged course of the disease and the occurrence of prolonged viremia. © 2017 John Wiley & Sons A/S.

We analysed the complications of 215 patients with uterine cervix cancer, treated by radiotherapy (RT) alone. It was done according to the rules of the Franco-Italian glossary, presented at the 7th ESTRO meeting, held in The Hague on September 1988. They were ranked by organ sites and by degrees of gravity. The analysis was done on the total number of complications and they were scored at the highest reached grade of gravity. Seventy one complications were found in 55 patients; they were studied by patient, degree of severity, time of onset, organ system and grade, time of onset and grade, time of onset and organ sites, stage and RT doses and brachytherapy volumes. The importance of the study of complications is stressed, particularly when treatment combines external RT and brachytherapy; some guidelines are given to avoid severe complications.

The analysis was done on the total number of complications and they were scored at the highest reached grade of gravity. Seventy one complications were found in 55 patients; they were studied by patient, degree of severity, time of onset, organ system and grade, time of onset and grade, time of onset and organ sites, stage and RT doses and brachytherapy volumes. The importance of the study of complications is stressed, particularly when treatment combines external RT and brachytherapy; some guidelines are given to avoid severe complications.

The incidence of fungal infection is significantly higher in patients with end-stage renal disease and renal transplant recipients than in normal individuals. Candida Albicans is an uncommon cause of abdominal wall abscess. We describe a 37 year-old renal transplant recipient with such an infection. He presented with a typical clinical manifestations and an insidious course, but was successfully treated with antifungal therapy. (author)

Objective: To assess the complications of percutaneous targeted Argon-Helium cryoablation treatment in patients with lung cancer on CT. Methods: Ten patients with unresectable lung cancer were treated by cryotherapy under CT guidance with Argon-Helium cryoablation system. Dynamic contrast-enhanced CT was performed to assess changes before and after treatment, complications and treatment response. Results: Ice ball coverage immediately after surgery was satisfactory in all patients. There were a few complications including worsening hoarseness (1), small pneumothorax (1), and small amount of bleeding at the site of probe puncture (1). Conclusion: Percutaneous targeted Argon-Helium cryoablation guided by CT is an effective treatment for lung cancer without severe complications. (authors)

When used appropriately, transfusion of red blood cells (RBCs) is a necessary life-saving therapy. However, RBC transfusions have been associated with negative outcomes such as infection and organ damage. Seeking explanations for the beneficial and deleterious effects of RBC transfusions is necessary to ensure the safe and optimal use of this precious resource. This study will create a framework to analyse the influence of blood donor characteristics on recipient outcomes. We will conduct a multisite, longitudinal cohort study using blood donor data routinely collected by Canadian Blood Services, and recipient data from health administrative databases. Our project will include a thorough validation of primary data, the linkage of various databases into one large longitudinal database, an in-depth epidemiological analysis and a careful interpretation and dissemination of the results to assist the decision-making process of clinicians, researchers and policymakers in transfusion medicine. Our primary donor characteristic will be age of blood donors and our secondary donor characteristics will be donor-recipient blood group compatibility and blood donor sex. Our primary recipient outcome will be a statistically appropriate survival analysis post-RBC transfusion up to a maximum of 8 years. Our secondary recipient outcomes will include 1-year, 2-year and 5-year mortality; hospital and intensive care unit length of stay; rehospitalisation; new cancer and cancer recurrence rate; infection rate; new occurrence of myocardial infarctions and need for haemodialysis. Our results will help determine whether we need to tailor transfusion based on donor characteristics, and perhaps this will improve patient outcome. Our results will be customised to target the different stakeholders involved with blood transfusions and will include presentations, peer-reviewed publications and the use of the dissemination network of blood supply organisations. We obtained approval from the

Full Text Available Abstract Background Infection with carbapenem-resistant Acinetobacter baumannii has been associated with high morbidity and mortality in solid organ transplant recipients. The main objective of this study was to assess the influence of carbapenem resistance and other potential risk factors on the outcome of A. baumannii infection after kidney and liver transplantation. Methods Retrospective study of a case series of A. baumannii infection among liver and renal transplant recipients. The primary outcome was death associated with A. baumannii infection. Multivariate logistic regression was used to assess the influence of carbapenem resistance and other covariates on the outcome. Results Forty-nine cases of A. baumannii infection affecting 24 kidney and 25 liver transplant recipients were studied. Eighteen cases (37% were caused by carbapenem-resistant isolates. There were 17 (35% deaths associated with A. baumannii infection. In unadjusted analysis, liver transplantation (p = 0.003, acquisition in intensive care unit (p = 0.001, extra-urinary site of infection (p A. baumannii infection. The number of deaths associated with A. baumannii infection was higher among patients infected with carbapenem-resistant isolates, but the difference was not significant (p = 0.28. In multivariate analysis, the risk of A. baumannii-associated mortality was higher in patients with infection acquired in the intensive care unit (odds ratio [OR] = 34.8, p = 0.01 and on mechanical ventilation (OR = 15.2, p = 0.04. Appropriate empiric antimicrobial therapy was associated with significantly lower mortality (OR = 0.04, p = 0.03, but carbapenem resistance had no impact on it (OR = 0.73, p = 0.70. Conclusion These findings suggest that A. baumannii-associated mortality among liver and kidney transplant recipients is influenced by baseline clinical severity and by the early start of appropriate therapy, but not by carbapenem

An observational study of health literacy and medication adherence in adult kidney transplant recipients

Background There is a high prevalence of non-adherence to immunosuppressants in kidney transplant recipients. Although limited health literacy is common in kidney recipients and is linked to adverse outcomes in other medical populations, its effect on medication adherence in kidney transplant recipients remains poorly understood. The objective was to investigate the effect of lower health literacy on immunosuppressant adherence. Methods Kidney recipients who were at least 6 months post-transp...

Islet transplantation is an attractive treatment for patients with insulin-dependent diabetes mellitus, and currently the liver is the favored transplantation site. However, an alternative site is desirable because of the low efficiency of hepatic transplantation, requiring 2-3 donors for a single recipient, and because the transplanted islets cannot be accessed or retrieved. We developed a novel procedure of islet transplantation to the inguinal subcutaneous white adipose tissue (ISWAT) of mice and described functional and morphological characteristics of transplanted syngeneic islets. Also, it was determined whether islet allograft rejection in the ISWAT can be prevented by immunosuppressive agents. Furthermore, it was examined whether human islets function when grafted in this particular site of immune-deficient mice. In this site, transplanted islets are engrafted as clusters and function to reverse STZ-induced diabetes in mice. Importantly, transplanted islets can be visualized by CT and are easily retrievable, and allograft rejection is preventable by blockade of co-stimulatory signals. Of much importance, the efficiency of islet transplantation in this site is superior to the liver, in which hyperglycemia of diabetic recipient mice is ameliorated after transplantation of 200 syngeneic islets (the islet number yielded from 1 mouse pancreas) to the ISWAT but not to the liver. Furthermore, human islets transplanted in this particular site function to reverse diabetes in immune-deficient mice. Thus, the ISWAT is superior to the liver as the site of islet transplantation, which may lead to improved outcome of clinical islet transplantation.

To report our early experience in image-guided chemoport insertions by interventional radiologists. This was a cross-sectional study conducted in a tertiary center with 161 chemoport insertions done from June 2008 to June 2010. The chemoports were inserted either at the angiography suite or at the mobile operation theater unit. Ninety percent of the chemoports had right internal jugular vein (IJV) as the entry site. Other entry sites included the left IJV, subclavian veins and the inferior vena cava. Immediate and early complications were recorded. All insertions were performed under image guidance with the aid of ultrasound and fluoroscopy. The technical success rate was 99.4%. In terms of immediate complications, there were only two cases of arterial puncture that resolved with local compression. No pneumothorax or air embolism was documented. Twenty-six early complications were recorded. The most common early complication was catheter blockage (12/161; 7.4%), followed by catheter-related infection (9/161; 5.6%). Other complications were catheter malposition, venous thrombosis and catheter dislodgement or leak. A total of 11 (6.8%) chemoports had to be removed within 30 days; most of them were due to infections that failed to respond to systemic antibiotic therapy. In terms of place of procedure, there were no significant differences in complication rates between the angiography suite and the mobile operation theater unit. Image-guided chemoport insertion by interventional radiologist gives low periprocedural complication rates. Using right IJV as the entry site, the image guidance gives good success rate with least complication

Compare the nutritional vulnerability, risk of malnutrition, nutritional status and quality of life (QoL) between recipients and non-recipients of nutrition care and support (NCS) of HIV-positive adults. In 2009, a household-based cross-sectional study of HIV-positive adults, NCS recipients (n=97) and non-NCS recipients (n=203) from KwaZulu-Natal was conducted. Nutritional vulnerability (socio-economic status; food security; self-reported health status; nutritional knowledge and attitude), risk of malnutrition (nutrition assessment screening tool), anthropometry (body mass index; mid-upper arm circumference; waist-to-hip ratio) and QoL (general health; self-care; physical functioning) were compared between the two groups. Although the result suggests a modest impairment of QoL, NCS recipients were twice as likely to have severe impairment of general health; self-care functioning and QoL. Overweight and obesity were common despite indications of high prevalence of food insecurity, possible-risk of malnutrition and diets predominantly of cereals. NCS recipients were more frequently taking anti-retroviral drugs, receiving social grants, reporting good eating plans and owning kitchen gardens. Non-NCS recipients had been generally sick, reported fatigue, nausea, appetite loss and diarrhoea. NCS recipients were twice as likely to experience oral thrush. Contextual factors such as low dietary diversity and household food insecurity that exacerbates nutritional vulnerability and malnutrition should be considered when providing NCS to fully achieve nutritional recovery and QoL of HIV-positive adults.

2009-05-15

In a randomized, international study comparing rabbit antithymocyte globulin (TMG) and basiliximab (BAS) induction in renal transplant recipients at risk for delayed graft function or acute rejection (n=278), TMG was associated with less acute rejection at 1 year. This study analyzed outcomes stratified by standard criteria donor (SCD), extended criteria donor (ECD), and hypertensive donor. Data-capture limitations necessitated defining ECD as donor age more than 60 years or 50 to 60 years with hypertension and renal insufficiency. Seventy-five recipients received ECD-kidneys (28.4% TMG vs. 25.6% BAS, P=NS) and 203 recipients received SCD-kidneys (72.6% TMG vs. 74.4% BAS, P=NS). Recipients of an ECD or hypertensive donor-kidney had similar outcomes between treatment groups. Recipients of an SCD-kidney treated with TMG had less rejection (odds ratio [OR] 0.48). Recipients of a normotensive donor-kidney treated with TMG had less rejection (OR 0.56). Recipients of a normotensive, SCD-kidney treated with TMG had less rejection (OR 0.47) and death (OR 0.17) than their counterparts treated with BAS. Contrary to its perceived niche in recipients of ECD-kidneys, TMG was most beneficial in patients who received a normotensive, deceased SCD kidney.

A number of evidence-based interventions have been proposed to reduce post-cesarean delivery wound complications. Examples of such interventions include appropriate timing of preoperative antibiotics, appropriate choice of skin antisepsis, closure of the subcutaneous layer if subcutaneous depth is ≥2 cm, and subcuticular skin closure with suture rather than staples. However, the collective impact of these measures is unclear. We sought to estimate the impact of a group of evidence-based surgical measures (prophylactic antibiotics administered before skin incision, chlorhexidine-alcohol for skin antisepsis, closure of subcutaneous layer, and subcuticular skin closure with suture) on wound complications after cesarean delivery and to estimate residual risk factors for wound complications. We conducted a secondary analysis of data from a randomized controlled trial of chlorhexidine-alcohol vs iodine-alcohol for skin antisepsis at cesarean delivery from 2011-2015. The primary outcome for this analysis was a composite of wound complications that included surgical site infection, cellulitis, seroma, hematoma, and separation within 30 days. Risk of wound complications in women who received all 4 evidence-based measures (prophylactic antibiotics within 60 minutes of cesarean delivery and before skin incision, chlorhexidine-alcohol for skin antisepsis with 3 minutes of drying time before incision, closure of subcutaneous layer if ≥2 cm of depth, and subcuticular skin closure with suture) were compared with those women who did not. We performed logistic regression analysis limited to patients who received all the evidence-based measures to estimate residual risk factors for wound complications and surgical site infection. Of 1082 patients with follow-up data, 349 (32.3%) received all the evidence-based measures, and 733 (67.7%) did not. The risk of wound complications was significantly lower in patients who received all the evidence-based measures compared with those who

Little is known about associations of family health history with outcomes after kidney donation. Using a database wherein Organ Procurement and Transplantation Network identifiers for 4650 living kidney donors in 1987 to 2007 were linked to administrative data of a US private health insurer (2000-2007 claims), we examined associations of recipient illness history as a measure of family history with postdonation diagnoses and drug-treatment for hypertension and diabetes. Cox regression with left and right censoring was applied to estimate associations (adjusted hazards ratios, aHR) of recipient illness history with postnephrectomy donor diagnoses, stratified by donor-recipient relationship. Recipient end-stage renal disease from hypertension, as compared with other recipient end-stage renal disease causes, was associated with modest, significant increases in the age- and gender-adjusted relative risks of hypertension diagnosis (aHR, 1.37%; 95% confidence interval [CI], 1.08-1.74) after donor nephrectomy among related donors. After adjustment for age, gender, and race, recipient type 2 diabetes compared with non-diabetic recipient status was associated with twice the relative risk of postdonation diabetes (aHR, 2.14; 95% CI, 1.28-3.55; P=0.003) among related donors. These patterns were significant among white but not among non-white related donors. Recipient type 1 diabetes was associated with postdonation diabetes only in black related donors (aHR, 3.22; 95% CI, 1.04-9.98; P=0.04). Recipient illness did not correlate significantly with outcomes in unrelated donors. These data support a need for further study of family health history as a potential sociodemographic correlate of donor outcomes, including examination of potential mediating factors and variation in risk discrimination among donors of different racial groups.

Intravenous fluid management for deceased donor kidney transplantation is an important, modifiable risk factor for delayed graft function (DGF). The primary objective of this study was to determine if goal-directed fluid therapy using esophageal Doppler monitoring (EDM) to optimize stroke volume (SV) would alter the amount of fluid given. This randomized, proof-of-concept trial enrolled 50 deceased donor renal transplant recipients. Data collected included patient characteristics, fluid administration, hemodynamics, and complications. The EDM was used to optimize SV in the EDM group. In the control group, fluid management followed the current standard of practice. The groups were compared for the primary outcome of total intraoperative fluid administered. There was no difference in the mean (standard deviation) volume of intraoperative fluid administered to the 24 control and 26 EDM patients [2,307 (750) mL vs 2,675 (842) mL, respectively; mean difference, 368 mL; 95% confidence interval (CI), - 87 to + 823; P = 0.11]. The incidence of complications in the control and EDM groups was similar (15/24 vs 17/26, respectively; P = 0.99), as was the incidence of delayed graft failure (8/24 vs 11/26, respectively; P = 0.36). Goal-directed fluid therapy did not alter the volume of fluid administered or the incidence of complications. This proof-of-concept trial provides needed data for conducting a larger trial to determine the influence of fluid therapy on the incidence in DGF in deceased donor kidney transplantation. www.clinicaltrials.gov (NCT02512731).

The Deferred Action for Childhood Arrivals (DACA) initiative provides for the temporary deferral of enforcement of immigration laws for certain undocumented individuals brought to the United States before age 16. More than 50 medical schools now consider applicants who are DACA recipients, and medical school graduates with DACA are eligible to continue their training in graduate medical education. In this article, the authors summarize current policy and provide data on DACA recipients in medical school. They then review the implications for considering DACA recipients in graduate medical education, including employment guidelines, employer responsibilities, training at Veterans Affairs facilities, research funding, and professional licensure. They conclude by discussing the future of the DACA program and best practices for supporting students who are DACA recipients.First, there are no employment restrictions for DACA recipients with valid work authorization documents as long as their employers use Form I-9 Employment Eligibility Verification. Second, unlike H-1B or J-1 visa holders, DACA recipients do not generate additional immigration-related costs for their residency programs. Next, provisions in the Civil Rights Act prohibit employers from discriminating against applicants based on national origin or, in some cases, citizenship status. Furthermore, trainees with DACA are eligible to rotate through Veterans Affairs facilities. Finally, some states, like California and New York, have adopted policies and regulations allowing trainees with DACA who meet all professional requirements to receive a medical license. Given this state of affairs, DACA recipients should have equal standing to their peers when being evaluated for residency positions.

Purpose: To evaluate the incidence and causes of complications associated with balloon-occluded arterial infusion chemotherapy (BOAI) for pelvic malignancies. Methods: In 34 courses of BOAI in 22 patients with pelvic malignancies, we analyzed the incidence of complications as well as the effect of the dose of the anticancer drugs, the infusion site, and the number of BOAI administrations on these complications. Complications were divided into two categories: cystitis-like symptoms and neurological complications such as pain, numbness, and paresthesia of the lower extremities and the hip. Results: Eleven patients (50%) suffered from complications, seven (31.8%) from neurological complications and four (18.2%) from cystitis-like symptoms. The complications appeared in 14 courses (42.4%) of BOAI, neurological complications in 10 (30.3%) and cystitis-like symptoms in four (12.1%). A high dose of anti-cancer drugs and infusion from the anterior division tended to induce neurological complications more frequently; however, the cystitis-like symptoms were not related to any factors. Conclusion: Our results indicate that a smaller dose of anti-cancer drugs should be infused from the bilateral internal iliac arteries for safer pelvic BOAI

The low graft-to-recipient weight ratio (GRWR) in adult-to-adult living donor liver transplantation (LDLT) is one of the major risk factors affecting graft survival. The goal of this study was to evaluate whether the lower limit of the GRWR can be safely reduced without portal pressure modulation in right-lobe LDLT. From 2005 to 2011, 317 consecutive patients from a single institute underwent LDLT with right-lobe grafts without portal pressure modulation. Of these, 23 had a GRWR of less than 0.7% (group A), 27 had a GRWR of ≥0.7%, recipient, donor, operation factors, laboratory findings and complications were reviewed retrospectively. The baseline demographics showed low model for end-stage liver disease score (mean 16.3+/-8.9) and high percentage of hepatocellular carcinoma (231 patients, 72.9%). Three groups by GRWR demonstrated similar characteristics except recipient body mass index and donor gender. For small-for-size syndrome, there were 3 (13.0%) in group A, 1 (3.7%) in group B, and 2 patients (0.7%) in group C (Pneed to modulate portal pressure in adult-to-adult LDLT using the right-lobe in favorable conditions including low model for end-stage liver disease score.

Full Text Available Purpose: To analyze the complications and their managements in Descemet′s stripping endothelial keratoplasty (DSEK in consecutive 430 cases by single surgeon in a tertiary eye hospital. Materials and Methods: 430 eyes of 366 patients with endothelial dysfunctions scheduled for DSEK, were analyzed retrospectively. In all cases donor dissection was performed manually, and ′Taco′ insertion and unfolding technique was used. Intra-operative and postoperative complications with their managements and outcomes were reviewed retrospectively. Periodic endothelial cell density was analyzed for each patient till the last visit. Follow-up period was between 3 to 60 months (mean 18.7 months. Results: 13 (3.0% eyes had operative complications during donor dissection and 16 (3.7% had during recipient procedure. In 7 (1.6% eyes, donor lenticule was replaced with a new one during the surgery. In early postoperative period, 21 (4.9% eyes had donor dislocation and 12 (2.8% eyes had air-induced pupillary block; and they were managed immediately. 2 cases had primary graft failure and in 1 case had postoperative bacterial endophthalmitis requiring evisceration. In late postoperative period, 48 (11.3% eyes had secondary glaucoma and 14 (3.3% eyes had late secondary graft failure. Endothelial rejection occurred in 5 (1.2% cases. Mean endothelial cell loss was 19.7% after 3 months and 54.2% after 5 years. Total graft failure in this series was 31 (7.2% and in 17 cases re-DSEK was performed successfully. Conclusions: Both operative and postoperative complications do occur in DSEK. Most of these complications can be managed by medical or appropriate surgical means. Some of the complications can be avoided and reduced with experience.

Ultrasonography was performed prospectively in 20 patients who were undergoing continuous ambullatory peritoneal dialysis for evaluation of complications. We examined the abdominal wall along the course of catheter and the peritoneal cavity with special attention to the dialysate distribution, dialysate echogenecity, thickness of the peritoneum small bowel distribution and the position of the catheter tip. Peritonitis was the most common complication (n=7); sonographic findings were small bowel adhesion (n=5) multiseptated ascites(n=1), peritoneal thickening(n=4), and tunnel infection(n=1) and exith site infection(n=1). Our initial experience suggests that ultrasonography is useful for diagnosis of complications and monitoring of patient during long term peritoneal dialysis

There is no consensus on how, when, and at what intensity exercise should be performed and organized after heart transplantation (HTx). Most rehabilitation programs are conducted in HTx centers, which might be impractical and costly. We have recently shown that high-intensity interval training (HIT) is safe, well tolerated, and efficacious in maintenance HTx recipients, but there are no studies among de novo patients, and whether HIT is feasible and superior to moderate training in HTx recipients is unclear. A total of 120 clinically stable HTx recipients older than 18 years will be recruited from 3 Scandinavian HTx centers. Participants are randomized to HIT or moderate training, shortly after surgery. All exercises are supervised in the patients' local communities. Testing at baseline and follow-up includes the following: VO2peak (primary end point), muscle strength, body composition, quality of life, myocardial performance, endothelial function, biomarkers, and progression of cardiac allograft vasculopathy. A subgroup (n = 90) will also be tested at 3-year follow-up to assess long-term effects of exercise. So far, the HIT intervention is well tolerated, without any serious adverse events. We aim to test whether decentralized HIT is feasible, safe, and superior to moderate training, and whether it will lead to significant improvement in exercise capacity and less long-term complications.

Bone marrow chimeras were prepared using reciprocal combinations of AKR and C3H mice. When C3H mice were recipients, the number of thymocytes recoverable from such chimeras (C3H recipient chimeras) was small as compared with that from chimeras for which AKR mice were used as recipients (AKR recipient chimeras) regardless of donor strain. The thymocytes from C3H recipient chimeras showed a profound deficiency in generating proliferative responses to stimulation by anti-CD3 mAb (2C11) or anti-TCR (alpha, beta) mAb (H57-597), even though the expression of CD3 and TCR molecules fell within the same range as that in AKR recipient chimeras. Furthermore, after stimulation with immobilized 2C11, the proportion of IL-2R+ cells in the thymocytes from C3H recipient chimeras was much less than that in AKR recipient chimeras. However, no significant difference in proliferative responses to 2C11 plus PMA, in influx of Ca2+ after stimulation with 2C11 or IL-2 production in response to 2C11 plus PMA or PMA plus A23187 was demonstrated between C3H and AKR recipient chimeras. These findings suggest that the thymocytes from C3H recipient chimeras have a deficiency in the signal transduction system as compared with chimeras for which AKR mice are the recipients. The thymic stromal component involved in this difference in the C3H recipient chimeras is discussed

Informal caregivers play a vital role in supporting seriously ill patients. However, informal caregiving is burdensome and can lead to negative health outcomes for the caregiver and the care recipient. The study's aim was to evaluate relationships among caregiver burden, care recipient depressive symptomology, and race. Guided by the social exchange perspective, we examined cross-sectional dyadic data from the National Long-Term Care Survey (N = 1279). Using ordinal logistic regression, we found that higher caregiver-reported objective burden was associated with higher care recipient depressive symptoms ( P exchange of the social good "helpful company" with a caregiver. These findings illustrate the importance of supporting reciprocal exchange as a promising component of maintaining balanced caregiver-care recipient relationships among black older adults and their informal caregivers.

An increasing number of cardiac transplants are being carried out around the world. With increasing longevity, these patients present a unique challenge to non-transplant anesthesiologists for a variety of transplant related or incidental surgeries. The general considerations related to a cardiac transplant recipient are the physiological and pharmacological problems of allograft denervation, the side-effects of immunosuppression, the risk of infection and the potential for rejection. A thorough understanding of the physiology of a denervated heart, need for direct vasoactive agents and post-transplant morbidities is essential in anesthetic management of such a patient. Here, we describe a case of a heart transplant recipient who presented for a cholecystectomy at our center.

Augmentation of transfer of experimental autoimmune thyroiditis (EAT) in mice by irradiation of recipients

Experimental autoimmune thyroiditis (EAT) can be adoptively transferred to normal syngeneic recipients using spleen cells from susceptible strains of mice primed in vivo with mouse thyroglobulin (MTg) and lipopolysaccharide (LPS) following in vitro activation of spleen cells by culture with MTg. Irradiation of recipient animals markedly augments the severity of thyroiditis induced in this system. Irradiation of recipients does not alter the time course of the development of thyroiditis, nor does it alter the requirement for both in vivo priming and in vitro activation of spleen cells for the development of EAT. Spleen cells from EAT-resistant strains of mice (e.g., Balb/c) do not induce EAT in irradiated recipients. Irradiated recipients develop significant levels of anti-MTg antibodies while unirradiated recipients have little detectable antibody response. The augmenting effect of irradiation can be substantially reversed by transferring naive spleen cells to recipients prior to the transfer of MTg/LPS-primed in vitro-activated spleen cells. In addition athymic CBA/Tufts nude mice develop more severe EAT than CBA/Tufts nude/+ littermates following transfer of activated CBA/J spleen cells. These data suggest that natural suppressor cells may regulate the development of EAT at the effector cell level

Stability and Longevity in the Publication Careers of U.S. Doctorate Recipients.

Directory of Open Access Journals (Sweden)

Cathelijn J F Waaijer

Full Text Available Since the 1950s, the number of doctorate recipients has risen dramatically in the United States. In this paper, we investigate whether the longevity of doctorate recipients' publication careers has changed. This is achieved by matching 1951-2010 doctorate recipients with rare names in astrophysics, chemistry, economics, genetics and psychology in the dissertation database ProQuest to their publications in the publication database Web of Science. Our study shows that pre-PhD publication careers have changed: the median year of first publication has shifted from after the PhD to several years before PhD in most of the studied fields. In contrast, post-PhD publication career spans have not changed much in most fields. The share of doctorate recipients who have published for more than twenty years has remained stable over time; the shares of doctorate recipients publishing for shorter periods also remained almost unchanged. Thus, though there have been changes in pre-PhD publication careers, post-PhD career spans remained quite stable.

Kaposi's Sarcoma (KS) is a tumour of multicentric origin with increased frequency after organ transplantation. To date, only North American data from the Cincinnati Transplant Tumor Registry have given some information about this disease in organ transplant recipients, but its true prevalence still has to be determined. In order to analyze Kaposi's sarcoma after kidney, liver and heart transplantation, we performed a retrospective study using the oldest registry of organ transplant recipients in Europe. Among all 7923 organ transplant recipients recorded in the Groupe Collaboratif de Recherche en Transplantation de l'Ile de France (GCIF) registry from 1968 to 1990, we analyzed the prevalence and the clinical characteristics of Kaposi's sarcoma in 6229 kidney, 727 liver and 967 heart transplant recipients. In the subgroup of kidney transplant recipients, we assessed the role of cyclosporine on disease evolution. Overall prevalence of Kaposi's sarcoma after organ transplantation was 0.52%, but it was significantly higher among liver (1.24%) than among kidney (0.45%) and heart (0.41%) transplant recipients. Chronic hepatitis B surface antigen carriers were more frequent in liver than in kidney transplant recipients who developed Kaposi's sarcoma (66% vs 21%, p < 0.03). Following kidney transplantation, Kaposi's sarcoma was more severe in patients receiving cyclosporine (n = 16) when compared with those under conventional immunosuppression (n = 12). True prevalence of Kaposi's sarcoma among European transplant recipients is high (0.52%) and appeared significantly higher in liver compared with other organ transplant recipients. Cyclosporine seems to increase severity of the disease among kidney transplant recipient.

Full Text Available Due to the increasing number and improved survival of lung transplant recipients, radiologists should be aware of the imaging features of the postoperative complications that can occur in such patients. The early treatment of complications is important for the long-term survival of lung transplant recipients. Frequently, HRCT plays a central role in the investigation of such complications. Early recognition of the signs of complications allows treatment to be initiated earlier, which improves survival. The aim of this pictorial review was to demonstrate the CT scan appearance of pulmonary complications such as reperfusion edema, acute rejection, infection, pulmonary thromboembolism, chronic rejection, bronchiolitis obliterans syndrome, cryptogenic organizing pneumonia, post-transplant lymphoproliferative disorder, bronchial dehiscence and bronchial stenosis.Com o número cada vez maior e uma melhor sobrevida dos pacientes submetidos ao transplante pulmonar, os radiologistas devem estar cientes das diversas possibilidades de complicações associadas ao transplante de pulmão. O tratamento precoce das complicações é importante para a sobrevida a longo prazo dos receptores de transplante pulmonar. Com frequência, a TCAR desempenha um papel central na investigação de tais complicações. O reconhecimento precoce dos sinais de complicações proporciona um tratamento rápido e melhora a sobrevida. O objetivo desta revisão pictórica foi proporcionar uma visão sobre as complicações mais prevalentes na TC, tais como edema de reperfusão, rejeição aguda, infecção, tromboembolismo pulmonar, rejeição crônica, síndrome da bronquiolite obliterante, pneumonia em organização criptogênica, doença linfoproliferativa pós-transplante, deiscência brônquica e estenose brônquica.

To asses the indications and complications of temporary loop ileostomy. This was a prospective cohort study conducted at Isra University Hospital, Hyderabad, Pakistan between February 2003 and August 2006. All patients who had temporary loop ileostomy during that period were included in this study. The indications and various postoperative complications were noted during postoperative hospital stay and subsequently during follow up till stoma were closed. Fifty six patients fulfilled the selection criteria during the study period. Typhoid (enteric) perforation was the most common indication of loop ileostomy accounting for about two thirds of all cases. Other indications were iatrogenic, covering ileostomy for rectal cancers, following resection anastomosis, tuberculosis, blunt abdominal trauma, anastomosis leak and rectovaginal fistula. Post operative skin excoriation was the most common complication while poor siting, transient edema, retraction and high output were other less common complications. Temporary loop ileostomy is the stoma of choice for temporary faecal diversion as most of its complications are manageable conservatively. (author)

Diagnostic imaging in liver transplantation. Preoperative evaluation and postoperative complications

Schroeder, T.; Ruehm, S.G.

2005-01-01

Complimentary to orthotopic liver transplantation (OLT), living donor liver transplantation (LDLT) is increasingly considered a therapeutic option in the therapy of end-stage liver disease. Accurate pre- and postoperative imaging is crucial for the transplantation success and represents an established part of the current evaluation algorithms. This article summarizes the most important requirements and the current imaging standards. Preoperative imaging is important for exclusion of transplantation contraindications in the recipient and for reliable assessment of anatomical variants in the donor. The main purpose of postoperative imaging is the early detection and characterization of complications. In both instances, multislice CT currently represents the most versatile and reliable imaging modality, still superior to MRI. For postoperative follow-up, the imaging modality of first choice is still bedside ultrasound; however, unclear findings usually need to be further assessed by CT. (orig.) [de

Murine cytomegalovirus immediate-early 1 gene expression correlates with increased GVHD after allogeneic hematopoietic cell transplantation in recipients reactivating from latent infection.

Directory of Open Access Journals (Sweden)

Senthilnathan Palaniyandi

Full Text Available The success of allogeneic (allo hematopoietic cell transplantation (HCT is limited by its treatment related complications, mostly graft versus host disease (GVHD and fungal and viral infections. CMV reactivation after HCT has been associated with increased morbidity and mortality, and a causal relation between GVHD, immunosuppressive therapy and vice versa has been postulated. Using a low GVHD severity murine HCT model, we assessed the role of MCMV reactivation and GVHD development. BALB/c mice were infected with either murine CMV (MCMV or mock and monitored for 25 weeks to establish latency, followed by sublethal irradiation conditioning and infusion of bone marrow plus splenocytes from either syngeneic (syn BALB/c or allo B10.D2 donors. Engraftment of allo donor cells was confirmed by PCR for D2Mit265 gene product size. Day+100 mortality and overall GVHD severity in allo MCMV pre-infected recipients was higher than in allo mock controls. Pathologic changes of lung and liver GVHD in immediate-early gene 1 (IE1 positive recipients were significantly increased compared to mock controls, and were only slightly increased in IE1 negative. No significant gut injury was seen in any group. Aggravated lung injury in IE1 positive recipients correlated with higher BAL cell counts both for total cells and for CD4+ T cells when compared with mock controls, and also with protein expression of lung IFN-gamma and liver TNF. No evidence for CMV specific morphologic changes was seen on histopathology in any organ of IE1 positive recipients, suggesting that CMV reactivation is related to increased GVHD severity but does not require active CMV disease, strengthening the concept of a reciprocal relationship between CMV and GVHD.

Full Text Available Rabbit antithymocyte globulin (ATG is commonly used as an induction therapy in renal transplant recipients, but the ideal dosage in tacrolimus-based early steroid withdrawal protocols has not been established. The purpose of this pilot study was to determine the immunophenotyping and efficacy of lower dose ATG in low immunological-risk kidney transplant recipients. In this prospective study, 45 patients were randomized (1∶1 to our standard dose ATG (total dose 3.75 mg/kg(sATG vs. lower dose 2.25 mg/kg (lowATG. All patients underwent early steroid withdrawal within 7 days. The primary end point was biopsy-proven acute rejection at 12 months. Prospective immunophenotyping of freshly isolated PBMCs was performed at baseline, 3, 6, 12 months post-transplant. The rate of acute rejection was 17% and 10% in the sATG and lowATG, respectively. Effector memory T cells, Tregs and recent thymic emigrants T cells had similar kinetics post-transplant in both groups. No statistically significant differences were found in graft survival, patient survival or infections between the two groups, though there was a non-significant increase in leukopenia (43%v s. 30%, CMV (8% vs. 0 and BK (4% vs. 0 infections in sATG group vs. lowATG. In sum, in low immunological risk kidney recipients undergoing steroid withdrawal, low dose ATG seems to be efficacious in preventing acute rejection and depleting T cells with potentially lower infectious complications. A larger study is warranted to confirm these findings.ClinicalTrials.gov NCT00548405.

Full Text Available Background: Considering the important role of pituitary gland in regulating various endocrine axes and its unique anatomical location, various postoperative complications can be anticipated resulting from surgery on pituitary tumors. We examined and categorized the immediate postoperative complications according to various tumor pathologies. Materials and Methods: We carried out a prospective study in 152 consecutive patients and noted various postoperative complications during neurosurgical intensive care unit stay (within 48 hrs of hospital stay in patients undergoing transsphenoidal removal of pituitary tumors. Results: In our series, various groups showed different postoperative complications out of which, cerebrospinal fluid leak was the commonest followed by diabetes insipidus, postoperative nausea and vomiting, and hematoma at operation site. Conclusion: Various immediate postoperative complications can be anticipated in transsphenoidal pituitary surgery even though, it is considered to be relatively safe.

Adipofascial Anterolateral Thigh Flap Safety: Applications and Complications

Full Text Available BackgroundA thinned anterolateral thigh (ALT flap is often harvested to achieve optimal skin resurfacing. Several techniques have been described to thin an ALT flap including an adipocutaneous flap, an adipofascial flap and delayed debulking.MethodsBy systematically reviewing all of the available literature in English and French, the present manuscript attempts to identify the common surgical indications, complications and donor site morbidity of the adipofascial variant of the ALT flap. The studies were identified by performing a systematic search on Medline, Ovid, EMBASE, the Cochrane Database of Systematic Reviews, Current Contents, PubMed, Google, and Google Scholar.ResultsThe study selection process was adapted from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, and 15 articles were identified using the study inclusion criteria. These articles were then reviewed for author name(s, year of publication, flap dimensions and thickness following defatting, perforator type, type of transfer, complications, thinning technique, number of cases with a particular area of application and donor site morbidity.ConclusionsThe adipofascial variant of the ALT flap provides tissue to fill large defects and improve pliability. Its strong and safe blood supply permits adequate immediate or delayed debulking without vascular complications. The presence of the deep fascia makes it possible to prevent sagging by suspending and fixing the flap for functional reconstructive purposes (e.g., the intraoral cavity. Donor site morbidity is minimal, and thigh deformities can be reduced through immediate direct closure or liposuction and direct closure. A safe blood supply was confirmed by the rate of secondary flap debulking.

End-stage renal disease (ESRD) is more common among Blacks, but Blacks are less likely to receive a live donor kidney transplant (LDKT). The objective of this study is to identify barriers and coping mechanisms that Black LDKT recipients and donors experienced while receiving or donating a kidney. A qualitative study was conducted using structured interviews. Thematic analysis was used for data interpretation. All 20 participants identified as Black, with two participants identifying themselves as multiracial. The mean age for the 14 recipients was 60, and the average age for the 6 living donors was 47. Themes emerging from the data suggest both recipients and donors faced barriers in the LDKT experience. Recipients faced barriers associated with their denial and avoidance of the severity of their ESRD, their desire to maintain the privacy of their health status, and their refusal to approach potential donors. Donors encountered negative responses from others about the donors' desire to donate and the initial refusal of recipients to accept a LDKT offer. Recipients identified faith as a coping mechanism, while donors identified normalization of donation as their method of coping. Various types of social support helped donors and recipients navigate the transplant process. Black LDKT recipients and donors must overcome barriers prior to receiving or donating a kidney. Most of these barriers arise from communication and interactions with others that are either lacking or undesirable. Future interventions to promote LDKT among Blacks may benefit by specifically targeting these barriers.

Nayak, Shobhana G.; Satish, R.; Gokulnath

2008-01-01

An increased risk of venous thromboembolism has been demonstrated following renal transplantation. Commonly reported sites have been deep vein thrombosis, pulmonary thromboembolism and vascular thrombosis involving the graft. Cerebral venous thrombosis (CVT) has not been reported in literature so far. A 36-year-old male patient, transplanted in January 2005 with normal graft functions, was admitted with history of headache, blurring of vision and vomiting. Examination revealed papilledema and no neurological deficits. Baseline investigations and analysis of cerebrospinal liquid were normal. Cerebral magnetic resonance venogram revealed extensive CVT involving superior sagittal sinus, bilateral transverse sinuses and the right sigmoid sinus. He was investigated for a thrombophilic disorder; serum homocysteine, protein C and S levels, antiphospholipid antibody and antithrombin-III levels were done despite which no conclusive diagnosis could be arrived at. To our knowledge, this is the first report of extensive CVT described in a transplant recipient. Ne definite prothrombotic or predisposing factors could be identified in our patient and the cause of CVT remains unclear. (author)

Kidney transplant recipients require lifelong treatment with immunosuppressive medications to avoid graft rejection and graft loss. Symptoms experienced may influence recipients' perceived quality of life and medication adherence. The purpose of this study was to evaluate the symptom experience associated with immunosuppressive medications in adult kidney transplant recipients and to explore the association between the symptom experience and adherence to immunosuppressive medications. A cross-sectional design was used. The study was conducted in a general hospital in China from October 2013 to September 2014. A total of 231 recipients with a follow-up of at least 1 year after kidney transplantation were included. Symptom experience associated with immunosuppressive medications was measured by the 13-item Symptom Experience of Immunosuppressive-related Side Effects Scale. Self-reported adherence to immunosuppressive medications was assessed using the Adherence with Immunosuppressive Medication Scale. Ridit analysis was used to rank symptom distress items. A proportion of 60.6% of recipients were male; the time after kidney transplantation was arbitrarily divided into a short-term cohort (1-4 years) and a long-term cohort (4-16 years) according to the median duration of follow-up (4 years). High blood pressure, hair loss, and tiredness were the three most distressing symptoms over all items of the whole sample. High blood pressure was the most distressing symptom for the 1- to 4-year cohort and the 4- to 16-year cohort. For men high blood pressure was the most distressing symptom, whereas for women hair loss was the most distressing symptom. Recipients in the 4- to 16-year cohort perceived a higher level of symptom distress compared with those in the 1- to 4-year cohort, especially in excess hair growth and difficulty sleeping. A negative relationship was found between symptom distress and adherence to immunosuppressive medications (r = -.541, p = .000). Recipients

A lack of donor hearts remains a major limitation of heart transplantation. Hearts from Centers for Disease Control (CDC) high-risk donors can be utilized with specific recipient consent. However, outcomes of heart transplantation with CDC high-risk donors are not well known. We sought to define outcomes, including posttransplant hepatitis and human immunodeficiency virus (HIV) status, in recipients of CDC high-risk donor hearts at our institution. All heart transplant recipients from August 2010 to December 2014 (n = 74) were reviewed. Comparison of 1) CDC high-risk donor (HRD) versus 2) standard-risk donor (SRD) groups were performed using chi-squared tests for nominal data and Wilcoxon two-sample tests for continuous variables. Survival was estimated with Kaplan-Meier curves. Of 74 heart transplant recipients reviewed, 66 (89%) received a SRD heart and eight (11%) received a CDC HRD heart. We found no significant differences in recipient age, sex, waiting list 1A status, pretransplant left ventricular assist device (LVAD) support, cytomegalovirus (CMV) status, and graft ischemia times (p = NS) between the HRD and SRD groups. All of the eight HRD were seronegative at the time of transplant. Postoperatively, there was no significant difference in rejection rates at six and 12 months posttransplant. Importantly, no HRD recipients acquired hepatitis or HIV. Survival in HRD versus SRD recipients was not significantly different by Kaplan-Meier analysis (log rank p = 0.644) at five years posttransplant. Heart transplants that were seronegative at the time of transplant had similar posttransplant graft function, rejection rates, and five-year posttransplant survival versus recipients of SRD hearts. At our institution, no cases of hepatitis or HIV occurred in HRD recipients in early follow-up. © 2016 Wiley Periodicals, Inc.

Bisphosphonates may prevent or treat the bone loss promoted by the immunosuppressive regimens used in renal transplantation. Risedronate is a commonly used third-generation amino-bisphosphonate, but little is known about its effects on the bone health of renal transplant recipients. We randomly assigned 42 new living-donor kidney recipients to either 35 mg of risedronate weekly or placebo for 12 months. We obtained bone biopsies at the time of renal transplant and after 12 months of protocol treatment. Treatment with risedronate did not affect bone mineral density (BMD) in the overall cohort. In subgroup analyses, it tended to preserve BMD in female participants but did not significantly affect the BMD of male participants. Risedronate did associate with increased osteoid volume and trabecular thickness in male participants, however. There was no evidence for the development of adynamic bone disease. In summary, further study is needed before the use of prophylactic bisphosphonates to attenuate bone loss can be recommended in renal transplant recipients.

Metabolic complications associated with use of diuretics.

Science.gov (United States)

Palmer, Biff F

2011-11-01

Diuretics are commonly used therapeutic agents that act to inhibit sodium transport systems along the length of the renal tubule. The most effective diuretics are inhibitors of sodium chloride transport in the thick ascending limb of Henle. Loop diuretics mobilize large amounts of sodium chloride and water and produce a copious diuresis with a sharp reduction of extracellular fluid volume. As the site of action of diuretics moves downstream (thiazide and potassium-sparing diuretics), their effectiveness declines because the transport systems they inhibit have low transport capacity. Depending on the site of action diuretics can influence the renal handling of electrolyte-free water, calcium, potassium, protons, sodium bicarbonate, and uric acid. As a result, electrolyte and acid-base disorders commonly accompany diuretic use. Glucose and lipid abnormalities also can occur, particularly with the use of thiazide diuretics. This review focuses on the biochemical complications associated with the use of diuretics. The development of these complications can be minimized with careful monitoring, dosage adjustment, and replacement of electrolyte losses. Copyright © 2011 Elsevier Inc. All rights reserved.

There is a high prevalence of non-adherence to immunosuppressants in kidney transplant recipients. Although limited health literacy is common in kidney recipients and is linked to adverse outcomes in other medical populations, its effect on medication adherence in kidney transplant recipients remains poorly understood. The objective was to investigate the effect of lower health literacy on immunosuppressant adherence. Kidney recipients who were at least 6 months post-transplant and outpatients of Vancouver General Hospital in B.C., Canada were recruited through invitation letters. A total of 96 recipients completed the Health Literacy Questionnaire, which provides a multifactorial profile of self-reported health literacy and the Transplant Effects Questionnaire-Adherence subscale measuring self-reported immunosuppressant adherence. Hierarchical linear regression was used to analyze the association between health literacy and adherence after controlling for identified risk factors of non-adherence. Our sample was on average 53 years old, 56% male and 9 years post-transplant. Kidney recipients reported low levels of health literacy on scales measuring active health management and critical appraisal of information and 75% reported non-perfect adherence. Worse adherence was associated with poorer overall health literacy (Δ R 2 = 0.08, P = 0.004) and lower scores on six of nine of the health literacy factors. Poorer health literacy is associated with lower immunosuppressant adherence in adult kidney transplant recipients suggesting the importance of considering a recipient's level of health literacy in research and clinical contexts. Medication adherence interventions can target the six factors of health literacy identified as being risk factors for lower medication adherence.

This study sought to explore the impact of care recipient falls on caregivers. Ninety-six community-dwelling caregiver-care recipient dyads participated in a 12-month prospective study. Falls and other accidents and service use were recorded. Dyads were assessed at baseline and after each fall. Assessment included the Zarit Burden Interview and a post-accident survey developed for the present study. Focus groups were then conducted to further explore the impact of falls on caregivers. Fifty-four care recipients (56%) experienced falls within the 12 months of the study. There was a significant increase in caregiver burden after the first fall (Zarit Burden Interview score increased from 24.2±14.2 to 27.6±14.5, Precipient alone. However, there was no increase in the number of services used. Focus group discussions highlighted the need for constant vigilance of the care recipient, a lack of knowledge about support services and concerns related to utilising respite care. Falls among care recipients have a significant impact on carers, including an increased fear of falling, prompting the need for even closer vigilance. WHAT IS KNOWN ABOUT THE TOPIC? Falls are a significant problem for older people as one in three older people fall each year and injurious falls are the leading cause of injury-related hospitalisation in older people. In Australia falls cost the economy over $500 million per year. WHAT DOES THIS PAPER ADD? This paper adds a unique perspective to the falls literature, that of the older person's carer. Falls are a significant problem for community-dwelling carers of older people, contributing to carer burden and impeding the carer's ability to undertake activities of daily living because of the perceived need for constant vigilance to prevent the person they care for from falling. WHAT ARE THE IMPLICATIONS FOR PRACTITIONERS? Practitioners should ensure that carers are aware of evidence-based falls-prevention practices and services, such as group and

To evaluate the radiological findings and clinical course of the complications arising after nonbiliay laparoscopic gastrointestinal surgery (NLGS). We retrospectively reviewed the clinical records of 131 patients who underwent NLGS (83 cases involving colorectal surgery, 18 splenectomies, 14 appendectomies, ten adrenalectomies, three lumbar sympathectomies, two Duhamel's operation, and one peptic ulcer perforation repair) over a four-year period. Among these 131 patients, the findings of fifteen in whom postoperative complications were confirmed were analysed. The radiologic examinations these patients underwent included CT (n=3D8), barium enema and fistulography (n=3D4), ultrasonography (n=3D3), ascending venography of the lower legs (n=3D2), and penile Doppler sonography (n=3D1). We evaluated the radiologic findings and clinical courses of early (within 2 weeks) and late (after 2 weeks) postoperative complications. Sixteen cases of postoperative complications developed in fifteen patients ; in 14 (17%) after colorectal surgery and in one (6%) after splenectomy. Eleven of the sixteen cases (69%) involved early complications, consisting of an abscess in three, ischemic colitis in two, hemoperitoneum in one, perforation of the colon in one, pancreatitis in one, recto-vaginal fistula in one, deep vein thrombosis after colorectal surgery in one, and abscess after splenectomy in one. The remaining five cases (31%) involved late complications which developed after colorectal surgery, comprising anastomosic site stricture in two, abdominal wall (trocar site) metastasis in one, colo-cutaneous fistula in one, and impotence in one. Among the 16 cases involving postoperative complications, recto-vaginal fistula, colon perforation, and abdominal wall metastasis were treated by surgery, while the other thirteen cases were treated conservatively. Various postoperative complications develop after NLGS, with a higher rate of these being noted in cases involving colorectal

Human herpesvirus 6 (HHV-6) species have a unique ability to integrate into chromosomal telomeres. Mendelian inheritance via gametocyte integration results in HHV-6 in every nucleated cell. The epidemiology and clinical effect of inherited chromosomally integrated HHV-6 (iciHHV-6) in hematopoietic cell transplant (HCT) recipients is unclear. We identified 4319 HCT donor-recipient pairs (8638 subjects) who received an allogeneic HCT and had archived pre-HCT peripheral blood mononuclear cell samples. We screened these samples for iciHHV-6 and compared characteristics of HCT recipients and donors with iciHHV-6 with those of recipients and donors without iciHHV-6, respectively. We calculated Kaplan-Meier probability estimates and Cox proportional hazards models for post-HCT outcomes based on recipient and donor iciHHV-6 status. We identified 60 HCT recipients (1.4%) and 40 donors (0.9%) with iciHHV-6; both recipient and donor harbored iciHHV-6 in 13 HCTs. Thus, there were 87 HCTs (2%) in which the recipient, donor, or both harbored iciHHV-6. Acute graft-versus-host disease (GVHD) grades 2-4 was more frequent when recipients or donors had iciHHV-6 (adjusted hazard ratios, 1.7-1.9; P = .004-.001). Cytomegalovirus viremia (any and high-level) was more frequent among recipients with iciHHV-6 (adjusted HRs, 1.7-3.1; P = .001-.040). Inherited ciHHV-6 status did not significantly affect risk for chronic GVHD, hematopoietic cell engraftment, overall mortality, or nonrelapse mortality. Screening for iciHHV-6 could guide donor selection and post-HCT risk stratification and treatment. Further study is needed to replicate these findings and identify potential mechanisms. © 2017 by The American Society of Hematology.

Safety of peritoneal and pleural drain placement in pediatric stem cell transplant recipients with severe veno-occlusive disease.

Hepatic VOD (veno-occlusive disease) is a serious complication of HSCT (hematopoietic stem cell transplantation) and has historically been associated with high mortality. This obstruction to hepatic flow often results in fluid collections in the peritoneal and pleural cavities. Catheter placement to drain ascites or pleural fluid may reduce intra-abdominal hypertension and/or improve respiratory parameters. The safety of these interventions among critically ill, immunocompromised children is unknown. Among 32 HSCT recipients (2000-2012) with severe VOD, we assessed the primary outcome of procedural complication from peritoneal drain placement. Twenty-four (75%) patients underwent peritoneal drain placement. No patient sustained visceral perforation or hemorrhage with drain placement. Overall mortality was 47% (n = 15). The procedure was not associated with increased overall mortality (p > 0.99). Eight (25%) peritoneal drains required replacement for malfunction. Of 24 patients with peritoneal drains, one (4%) patient had a positive culture from ascitic fluid. Eight (25%) patients underwent pleural drain placement. No pleural drain-related procedural complication or infection occurred. Four (50%) of the eight patients with pleural drains had de-escalation in oxygen requirement at drain removal, compared to time of placement. In this study, peritoneal and pleural drains were safe interventions for children with severe VOD. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Full text: Allogenic bone-marrow grafting in 24 human leukaemic subjects is described. The graft failed in 7 cases and took in 17 cases. In the latter group, all 17 cases were complicated by the secondary syndrome which was-fatal in 13 cases and controlled in 4 cases. The immunogenetic and immunological factors determining the establishment and evolution of haematological radiochimeras in man are discussed. The choice of donor is fundamental. Three tests are effective in donor selection, the indirect histocompatibility test, the leucocyte antigen test and the reaction of donor and recipient leucocytes in the dermis of an irradiated hamster. When marrow from several donors is transfused, the recipient spontaneously selects the genetically nearest. It seems likely there is more chance of finding a suitable donor among genetically related subjects than among those who are unrelated. The frequency of graft take seems slightly lower in recipients who have previously received blood transfusions. Total bone-marrow graft is associated with specific tolerance towards donor tissues. This is paralleled by the production in the chimera of immunoglobulins produced by the graft. The secondary syndrome seems, as in animals, to be related essentially to the graft-versus-host reaction. It is convenient to distinguish among its various manifestations, on the one hand, those lesions which are readily controlled such as hepatitis or erythrodermia associated with infiltration and proliferation of immunologically competent cells from the graft and, on the other hand, immune insufficiency with regard to micro-organisms, especially viruses and Candida albicans. This latter group, the mechanism of which is complex, still eludes attempts at preventive and curative control. The use of multiple donors and the administration of cortisone during marrow transfusion and A-methopterin and/or cyclophosphamide in the days following transfusions; seem to have reduced the severity of the secondary

Surgical site infection is more frequent in liver transplantation than in other types of solid organ transplantation with different antibiotics. Studies have shown that the rate of surgical site infection varies from 8.8% to 37.5% after liver transplantation. Therefore, antimicrobial prophylaxis is likely an essential tool for reducing these infections. However, the literature lacks evidence indicating the best prophylactic antibiotic regimen that can be used for liver transplantation. To assess the benefits and harms of antibiotic prophylactic regimens for surgical site infection in people undergoing liver transplantation. We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Science Citation Index Expanded and Latin American Caribbean Health Sciences Literature (LILACS). The most recent search was performed on 11 September 2015. All eligible randomised clinical trials comparing any antibiotic regimen versus placebo, versus no intervention or versus another antibiotic regimen for surgical site infection in liver transplant recipients, regardless of age, sex and reason for transplantation. Quasi-randomised studies and other observational studies were considered for data on harm if retrieved with search results for randomised clinical trials. Two review authors selected relevant trials, assessed risk of bias of studies and extracted data. The electronic search identified 786 publications after removal of duplicates. From this search, only one seemingly randomised clinical trial, published in abstract form, fulfilled the inclusion criteria of this review. This trial was conducted at Shiraz Transplant Centre, Shiraz, Iran, where investigators randomly assigned a total of 180 consecutive liver transplant recipients. We judged the overall risk of bias of the trial published in abstract form as high. Researchers reported no numerical data but mentioned that 163 participants

Owing to limited availability of donor organs, previous solid organ transplant (SOT) recipients are increasingly considered as potential organ donors. We report donor-derived transmission of herpes simplex virus type-2 (HSV-2) to two clusters of SOT recipients with transmission from the original donor and an HSV-2-infected recipient who subsequently became a donor. We reviewed medical records of the donors and recipients in both clusters. Pre-transplant serology and virological features of HSV-2 were characterized. Genotyping of HSV-2 isolates to determine potential for donor transmission of HSV-2 through transplantation of organs from prior organ recipients was performed. A kidney-pancreas recipient died day 9 post transplant. Following confirmation of brain death, the lungs and recently transplanted kidney were donated to two further recipients. The liver was not retrieved, but biopsy confirmed HSV-2 infection. Testing on the original donor showed negative HSV-2 polymerase chain reaction and HSV immunoglobulin (Ig)M, but positive HSV-2 IgG. The liver recipient from the original donor developed HSV-2 hepatitis and cutaneous infection that responded to treatment with intravenous acyclovir. In the second cluster, lung and kidney recipients both developed HSV-2 viremia that was successfully treated with antiviral therapy. Genotyping of all HSV-2-positive samples showed 100% sequence homology for three recipients. Donor-derived HSV infection affected two clusters of recipients because of transplantation of organs from a prior organ recipient. HSV should be considered as a possible cause of illness in febrile SOT recipients in the immediate post-transplant period and may cause disseminated disease and re-infection in HSV-2-seropositive recipients. Testing of HSV serology and prophylaxis may be considered in SOT recipients not receiving cytomegalovirus prophylaxis. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To describe the pulmonary complications following hematopoietic stem cell transplantation (HSCT) that can present with a 'crazy-paving' pattern in high-resolution CT scans. Retrospective review of medical records from 2,537 patients who underwent HSCT. The 'crazy-paving' pattern consists of interlobular and intralobular septal thickening superimposed on an area of ground-glass attenuation on high-resolution CT scans. The CT scans were retrospectively reviewed by two radiologists, who reached final decisions by consensus. We identified 10 cases (2.02%), seven male and three female, with pulmonary complications following HSCT that presented with the 'crazy-paving' pattern. Seven (70%) patients had infectious pneumonia (adenovirus, herpes simplex, influenza virus, cytomegalovirus, respiratory syncytial virus, and toxoplasmosis), and three patients presented with non-infectious complications (idiopathic pneumonia syndrome and acute pulmonary edema). The 'crazy-paving' pattern was bilateral in all cases, with diffuse distribution in nine patients (90%), predominantly in the middle and inferior lung regions in seven patients (70%), and involving the anterior and posterior regions of the lungs in nine patients (90%). The 'crazy-paving' pattern is rare in HSCT recipients with pulmonary complications and is associated with infectious complications more commonly than non-infectious conditions.

Background Postoperative measurements of compound action potentials are not always possible due to the insufficient acceptance of the CI-recipients. This study investigated the impact of different parameters on the acceptance of the measurements. Methods Compound action potentials of 16 CI recipients were measured with different pulse-widths. Recipients performed a loudness rating at the potential thresholds with the different sequences. Results Compound action potentials obtained with higher pulse-widths were rated softer than those obtained with smaller pulse-widths. Conclusions Compound action potentials measured with higher pulse-widths generate a gap between loudest acceptable presentation level and potential threshold. This gap contributes to a higher acceptance of postoperative measurements. Georg Thieme Verlag KG Stuttgart · New York.

An Algorithm Measuring Donor Cell-Free DNA in Plasma of Cellular and Solid Organ Transplant Recipients That Does Not Require Donor or Recipient Genotyping

Full Text Available Cell-free DNA (cfDNA has significant potential in the diagnosis and monitoring of clinical conditions but accurately and easily distinguishing the relative proportion of DNA molecules in a mixture derived from two different sources (i.e. donor and recipient tissues after transplantation is challenging. In human cellular transplantation there is currently no useable method to detect in vivo engraftment and blood-based non-invasive tests for allograft rejection in solid organ transplantation are either non-specific (e.g. creatinine in kidney transplantation, liver enzymes in hepatic transplantation or absent (i.e. heart transplantation. Elevated levels of donor cfDNA have been shown to correlate with solid organ rejection but complex methodology limits implementation of this promising biomarker. We describe a cost-effective method to quantify donor cfDNA in recipient plasma using a panel of high-frequency single nucleotide polymorphisms, next-generation (semiconductor sequencing and a novel mixture model algorithm. In vitro, our method accurately and rapidly determined donor/recipient DNA admixture. For in vivo testing, donor cfDNA was serially quantified in an infant with a urea cycle disorder after receiving six daily infusions of donor liver cells. Donor cfDNA isolated from 1-2 ml of recipient plasma was detected as late as 24 weeks after infusion suggesting engraftment. The percentage of circulating donor cfDNA was also assessed in pediatric and adult heart transplant recipients undergoing routine endomyocardial biopsy with levels observed to be stable over time and generally measuring <1% in cases without moderate or severe cellular rejection. Unlike existing non-invasive methods used to define the proportion of donor cfDNA in solid organ transplant patients, our assay does not require sex mismatch, donor genotyping or whole-genome sequencing and potentially has broad application to detect cellular engraftment or allograft injury after

Full Text Available Abstract Background In the Czech Republic, two-dose immunization against mumps achieves 98 % coverage. The routine reporting detects mumps cases, clinical complications, and hospital admissions in unvaccinated but also in vaccinated individuals. Using surveillance data of patients with mumps we assessed the effectiveness of mumps vaccination on mumps clinical complications and hospitalization need. We also investigated the effect of the time since immunization. Methods We analysed data on incident mumps cases reported to the Czech national surveillance system in 2007–2012. Using a logistic regression model with adjustment for age, sex, year of onset, and the administrative region, the association between vaccination and the most frequent mumps complications and hospitalization was evaluated. The adjusted odds ratios (ORa for mumps complications were compared between the vaccinated and non-vaccinated groups, reflecting the vaccine effectiveness (VEa computed as VEa = (1-ORa×100. We estimated the risk of mumps complications by the time from vaccination. Results From total of 9663 mumps analysed cases 5600 (58 % occurred in males. The mean age at the disease onset was 17.3, median 16 years. Ninety percent of the study patients had no complications, while 1.6 % developed meningitis, 0.2 % encephalitis, and 0.6 % pancreatitis. Mumps orchitis occurred in 659 (11.8 % male cases. In total, 1192 (12.3 % patients required hospitalization. Two doses of vaccine received by 81.8 % cases significantly reduced the risk of hospitalization: ORa 0.29 (95 % CI: 0.24, 0.35. Two doses showed statistically significant VEa 64 % (95 % CI: 46, 79 for meningitis, 93 % (95 % CI: 66, 98 for encephalitis in all cases, and 72 % (95 % CI: 64, 78 for orchitis in males.

2015-11-01

The purpose of this study was to investigate the relationship between immunosuppressant-related symptom experience (SE) and adherence to immunosuppressant regimens among kidney transplant (KT) recipients. A total of 239 KT recipients on an immunosuppressant regimen who were followed up after transplantation participated in this study. Data was collected through a self-reported questionnaire survey (medication adherence, SE, and quality of life) and medical record review. Low adherence in the immunosuppressant group was associated with longer time since KT, less comorbidity (adherence among KT recipients showed significantly greater overall symptom occurrence (P = .001) and symptom distress (P = .002) levels than patients with high or medium adherence after adjusting for a number of covariates. The most common symptom both in terms of occurrence (96.4%) and distress (91.1%) among poorly adherent KT recipients was tiredness. Low adherence to an immunosuppressant regimen was significantly associated with high SE among KT recipients. Strategies to decrease immunosuppressant-related SE are needed to improve adherence to immunosuppressants. Copyright © 2015 Elsevier Inc. All rights reserved.

Paitients and methods: We retrospectively reviewed a database of 188 patients who underwent resection for colorectal cancer with laparoscopic surgery between July 2007 and March 2015. The prognostic nutrition index(PNI), modified Glas- gow prognostic score(mGPS), controlling nutritional status(CONUT), and neutrophil/lymphocyte ratio(N/L)were measured in these patients. We examined the association between postoperative complications and clinicopathological factors. The study included 110 men and 78 women. Median age was 68 years. The site of the primary lesion was colon in 118 and rectum in 70 patients. Postoperative complications higher than Grade II(Clavien-Dindo classification)were reported in 24(12.8%)patients: Surgical site infection(SSI)in 12, remote infection in 7, ileus in 5, and others in 2 patients. Clinicopathological factors related to complications were rectal surgery, large amount of intraoperative bleeding, and long operative time. The related immunologic and nutritional factors were mGPS 2, PNI below 40, and N/L above 3. CONUT was not associated with complications in ourcases. mGPS, PNI, and N/L are predictive factors for complications in laparoscopic colorectal surgery.

To explore the music appreciation of prelingually deaf adults using cochlear implants (CIs). Cohort study. Adult CI recipients were recruited based on hearing history and asked to complete the University of Canterbury Music Listening Questionnaire (UCMLQ) to assess each individual's music listening and appreciation. Results were compared to previous responses to the UCMLQ from a large cohort of postlingually deaf CI recipients. Fifteen prelingually deaf and 15 postlingually deaf adult cochlear implant recipients. No significant differences were found between the prelingual and postlingual participants for amount of music listening or music listening enjoyment with their CI. Sound quality of common instruments was favourable for both groups, with no significant difference in the pleasantness/naturalness of instrument sounds between the groups. Prelingually deaf CI recipients rated themselves as significantly less able to follow a melody line and identify instrument styles compared to their postlingual peers. The results suggest that the pre- and postlingually deaf CI recipients demonstrate equivalent levels of music appreciation. This finding is of clinical importance, as CI clinicians should be actively encouraging all of their recipients to explore music listening as a part of their rehabilitation.

The flaps were anastomosed in a perforator to perforator manner using supermicrosurgery technique.Minimum of 3 perforators were traced around the knee defect. All flaps survived attached to a recipient perforator with artery diameter ranging from 0.4 to 0.9 mm and accompanying veins ranging from 0.4 to 1.2 mm. This approach allowed reduction in time for pedicle and recipient vessel dissection and minimized the trauma involved during isolation of the vessels.Using the perforator as recipient vessel allows an increase in selection for choice of recipient. By using a perforator as recipient, less time is consumed to secure the vessel, does not need long pedicles for flap, is not bound by the condition of major arteries, and minimizes any risk for major vessel injury while having acceptable flap survival.

Objectives This study (a) examined speech recognition abilities of cochlear implant (CI) recipients in the spectrally complex listening condition of three contrasting types of background music, and (b) compared performance based upon listener groups: CI recipients using conventional long-electrode (LE) devices, Hybrid CI recipients (acoustic plus electric stimulation), and normal-hearing (NH) adults. Methods We tested 154 LE CI recipients using varied devices and strategies, 21 Hybrid CI recipients, and 49 NH adults on closed-set recognition of spondees presented in three contrasting forms of background music (piano solo, large symphony orchestra, vocal solo with small combo accompaniment) in an adaptive test. Outcomes Signal-to-noise thresholds for speech in music (SRTM) were examined in relation to measures of speech recognition in background noise and multi-talker babble, pitch perception, and music experience. Results SRTM thresholds varied as a function of category of background music, group membership (LE, Hybrid, NH), and age. Thresholds for speech in background music were significantly correlated with measures of pitch perception and speech in background noise thresholds; auditory status was an important predictor. Conclusions Evidence suggests that speech reception thresholds in background music change as a function of listener age (with more advanced age being detrimental), structural characteristics of different types of music, and hearing status (residual hearing). These findings have implications for everyday listening conditions such as communicating in social or commercial situations in which there is background music. PMID:23342550

Since the 1950s, the number of doctorate recipients has risen dramatically in the United States. In this paper, we investigate whether the longevity of doctorate recipients’ publication careers has changed. This is achieved by matching 1951-2010 doctorate recipients in astrophysics, chemistry, economics, genetics and psychology with rare names in the dissertation database ProQuest to their publications in the publication database Web of Science. Our study shows that post-PhD publication career spans have not changed much in most fields, with the share of doctorate recipients who have published for over twenty years having remained stable over time.

Total ankle arthroplasty (TAA) is an increasingly used, effective treatment for end-stage ankle arthritis. Although numerous studies have associated blood transfusion with complications following hip and knee arthroplasty, its effects following TAA are largely unknown. This study uses data from a large, nationally representative database to estimate the association between blood transfusion and inpatient complications and hospital costs following TAA. Using the Nationwide Inpatient Sample (NIS) database from 2004 to 2014, 25 412 patients who underwent TAA were identified, with 286 (1.1%) receiving a blood transfusion. Univariate analysis assessed patient and hospital factors associated with blood transfusion following TAA. Patients requiring blood transfusion were more likely to be female, African American, Medicare recipients, and treated in nonteaching hospitals. Average length of stay for patients following transfusion was 3.0 days longer, while average inpatient cost was increased by approximately 50%. Patients who received blood transfusion were significantly more likely to suffer from congestive heart failure, peripheral vascular disease, hypothyroidism, coagulation disorder, or anemia. Acute renal failure was significantly more common among patients receiving blood transfusion ( P < .001). Blood transfusions following TAA are infrequent and are associated with multiple medical comorbidities, increased complications, longer hospital stays, and increased overall cost. Level III: Retrospective, comparative study.

Irradiation remains the mainstay of treatment of nasopharyngeal carcinoma in the primary site and the neck. We studied the long-term effects of irradiation in five patients who have survived ten or more years after treatment without recurrence of disease, and we were impressed by the rarity of disabling complications of the treatment. Minor complications were common, and especially troublesome were xerostomia, dental caries, postnasal crusting and neck weakness. (author)

Cytomegalovirus (CMV) is the most common viral infection following kidney transplant, has been recognized as a major factor for graft loss and increased incidence of acute rejection. Different studies have reported a variable incidence of CMV disease with the use of Mycophenolate mofetil (MMF). We retrospectively analyzed our renal transplant recipients to review the results of CMV disease and to compare CMV disease in patient on Azathioprine and MMF for this purpose we retrospectively reviewed 521 live related kidney transplant recipients at our institute. 74 (14.2 %) live related allograft recipients developed CMV disease after a median interval of 7.18 ± 4.35 months from transplantation. The mean age was 36.15 ± 10.7 years. 63 of the patients were male. Malaise, fever and diarrhea were among most common symptoms. 20 (27.02 %) of the 74 recipients developed transaminitis, 13 (17.2 %) developed CMV gastritis, 5 (9.13 %) recipients developed pneumonia, and 3 (4.05 %) patient developed colitis. 59 (80 %) patients had leucopenia and 41 (56.5 %) developed thrombocytopenia. Mean serum creatinine level was 1.5 ± 0.4 (0.9-2.4) mg/dl before the disease, 1.9 ± 0.6 (1.3-3.6) mg/dl at the time of the diagnosis, and 1.7 ± 0.06 (0.8-4.2) mg/dl at the end of the treatment. CMV disease developed in 9 (36 %) of recipients who received basiliximab as induction therapy and 13 (30.24 %) of recipients who received ATG (p > 0.05). The incidence of CMV disease was similar in cyclosporine based regimen (13.2 %) and Tacrolimus based regimen 27 (16.16 %) (p = 0.137) and was also similar in Azathioprine 41 (9.5 %) and MMF group 33 (14.3 %) (p = 0.163). There was no significant difference in severity of CMV disease in both groups, except a higher incidence of leucopenia in Azathioprine group (86 vs. 74 %, p < 0.05) as compared to MMF group. 51 (68.91 %) patient developed graft dysfunction during CMV disease. In conclusion we report a low incidence

Full Text Available To study the effect of immunosuppressive reduction on the incidence and consequence of late acute rejection (LAR in liver allograft recipients, mean daily prednisone dose, mean cyclosporine A (CsA trough and nadir levels were retrospectively reviewed for the nearest 12-week period preceding six episodes of LAR in five liver allograft recipients (group 1. Results were compared with those from a cohort of 12 liver allograft recipients who did not develop LAR (group 2. LAR was defined as acute rejection occurring more than 365 days post-transplantation. Median follow-up for both groups was similar (504 days, range 367 to 1050, versus 511 days, range 365 to 666, not significant. Mean trough CsA levels were lower in patients with LAR compared with those without (224±66 ng/mL versus 233±49 ng/mL but the difference was not statistically significant. In contrast, mean daily prednisone dose (2.5±1.6 mg/ day versus 6.5±2.9 mg/day, P=0.007 and CsA nadir values (129±60 ng/mL versus 186±40 ng/mL, P=0.03 were significantly lower in patients who developed LAR compared with those who did not. Five of six episodes (83% of LAR occurred in patients receiving less than 5 mg/day of prednisone, versus a single LAR episode in only one of 12 patients (8% receiving prednisone 5 mg/day or more (P=0.004. In all but one instance, LAR responded to pulse methylprednisolone without discernible affect on long term graft function. The authors conclude that liver allograft recipients remain vulnerable to acute rejection beyond the first post-transplant year; and reduction of immunosuppressive therapy, particularly prednisone, below a critical, albeit low dose, threshold increases the risk of LAR.

Infections caused by Acinetobacter baumannii in recipients of hematopoietic stem cell transplantation

Khalid Ahmed Al-Anazi

2014-07-01

Full Text Available Acinetobacter baumannii (A. baumannii is a Gram-negative, strictly aerobic, non-fermentative coccobacillus which is widely distributed in nature. Recently, it has emerged as a major cause of health care-associated infections in addition to its capacity to cause community acquired infections. Risk factors for A. baumannii infections and bacteremia in recipients of hematopoietic stem cell transplantation include: severe underlying illness such as hematological malignancy, prolonged use of broad-spectrum antibiotics, invasive instrumentation such as central venous catheters or endotracheal intubation, colonization of respiratory, gastrointestinal or urinary tracts in addition to severe immunosuppression caused by using corticosteroids for treating graft versus host disease. The organism causes a wide spectrum of clinical manifestations, but serious complications such as bacteremia, septic shock, ventilator-associated pneumonia, extensive soft tissue necrosis and rapidly progressive systemic infections that ultimately lead to multiorgan failure and death are prone to occur in severely immunocompromised hosts. The organism is usually resistant to many antimicrobials including penicillins, cephalosporins, trimethoprim-sulfamethoxazole, almost all flouroquinolones and most of the aminoglycosides. The recently increasing resistance to carbapenems, colistin and polymyxins is alarming. Additionally, there are geographic variations in the resistance patterns and several globally and regionally resistant strains have already been described. Successful management of A.baumannii infections depends upon appropriate utilization of antibiotics and strict application of preventive and infection control measures. In uncomplicated infections, the use of a single active beta-lactam may be justified, while definitive treatment of complicated infections in critically ill individuals may require drug combinations such as colistin and rifampicin or colistin and

Full Text Available Scrub typhus is a rickettsial infection commonly seen in Asia. The clinical presentation ranges from nonspecific febrile illness to potentially fatal multiorgan involvement such as liver, kidney, or lung. Central nervous system involvement is uncommon. We report a 45-year-old female renal transplant recipient who presented with fever, headache, meningeal signs, graft dysfunction, and eschar. IgM antibodies against Orientia tsutsugamushi were positive by enzyme-linked immunosorbent assay. Despite oral doxycycline therapy for 5 days, she did not improve but responded well to intravenous azithromycin. To the best of our knowledge, scrub typhus as a cause of meningitis in a renal transplant recipient has not been reported so far.

Full Text Available Abstract Background Guidelines for safe gamete donation have emphasised donor screening, although none exist specifically for testing oocyte recipients. Pre-treatment assessment of anonymous donor oocyte IVF treatment in Ireland must comply with the European Union Tissues and Cells Directive (Directive 2004/23/EC. To determine the effectiveness of this Directive when applied to anonymous oocyte recipients in IVF, we reviewed data derived from selected screening tests performed in this clinical setting. Methods Data from tests conducted at baseline for all women enrolling as recipients (n = 225 in the anonymous oocyte donor IVF programme at an urban IVF referral centre during a 24-month period were analysed. Patient age at programme entry and clinical pregnancy rate were also tabulated. All recipients had at least one prior negative test for HIV, Hepatitis B/C, chlamydia, gonorrhoea and syphilis performed by her GP or other primary care provider before reproductive endocrinology consultation. Results Mean (±SD age for donor egg IVF recipients was 40.7 ± 4.2 yrs. No baseline positive chlamydia, gonorrhoea or syphilis screening results were identified among recipients for anonymous oocyte donation IVF during the assessment interval. Mean pregnancy rate (per embryo transfer in this group was 50.5%. Conclusion When tests for HIV, Hepatitis B/C, chlamydia, gonorrhoea and syphilis already have been confirmed to be negative before starting the anonymous donor oocyte IVF sequence, additional (repeat testing on the recipient contributes no new clinical information that would influence treatment in this setting. Patient safety does not appear to be enhanced by application of Directive 2004/23/EC to recipients of anonymous donor oocyte IVF treatment. Given the absence of evidence to quantify risk, this practice is difficult to justify when applied to this low-risk population.

The high demand for organs for transplantation has made it necessary to consider using even the oldest and youngest of potential donors in order to increase the organ supply. In this retrospective study, the outcome of kidney transplantation using cadaveric pediatric donors was compared with that of an adult control series. Graft procurement took place in two regions of Italy (Emilia-Romagna and Piemonte) over an 11-year period. A group of pediatric donors (Actuarial patient and graft survival rates did not differ significantly between the two groups (patient survival 96% and 96% for pediatric donors versus 98% and 92% for adult donors at 1 and 5 years post-transplantation; graft survival 76% and 68% for pediatric donors versus 88% and 74% for adult donors 1 and 5 y post-transplantation). Complications were also evaluated, but no difference was found (the only exception being the creatinine level in the 5th year). Renal transplantation with cadaveric donors starting at 4 years of age gave results comparable to kidneys coming from adults. These data show that cadaveric pediatric donor kidneys may be used in adult recipients with good results. The ethical implications of the subject are extensively reviewed.

Recent studies have indicated that bone marrow-derived stromal cells (BMSCs) have immunomodulatory properties that suppress the T cell responses that cause graft rejection. The purpose of this study is to evaluate the effect of recipient BMSCs intravenous infusion for immunomodulation in a rat vascularized composite allotransplantation model. A total of nine Wistar (WIS) rats and thirty Lewis (LEW) rats were used. BMSCs were harvested from three LEW rats. Twenty-four LEW rats were used as recipients and divided randomly into four groups: BMSC group, FK group, UT group, and Iso group. In the BMSC group, orthotopic rat hind limb transplantation was performed between WIS donor and LEW recipient rats. Recipient rats were injected intravenously with 2 × 10 6 recipient BMSCs on day 6, and with 0.2 mg/kg/day tacrolimus administered over 7 days (n = 6). In the FK group, recipient rats were treated with tacrolimus alone (n = 6). Rats in the UT group received no immunosuppressive treatment (n = 6). In the Iso group, transplantation was performed from three LEW donor rats to six LEW recipient rats without any immunosuppressive treatment (n = 6). Graft survival was assessed by daily inspection and histology. The immunological reactions of recipients were also evaluated. The graft survival of recipient rats in the BMSC group (24.5 days) was significantly prolonged in comparison with that of the FK group (18 days) (P Recipient rats in the BMSC group had significantly reduced serum IFN-γ cytokine levels (1.571 ± 0.779 pg/ml) in comparison with that of the FK group (7.059 ± 1.522 pg/ml) (P = .001). In in vitro study, BMSCs induce T cell hyporesponsiveness in a mixed lymphocyte reaction. BMSCs induce T cell hyporesponsiveness and prolong graft survival in the rat vascularized composite allotransplantation model. BMSCs exhibit immunomodulatory properties against acute rejection that can be realized without the need for significant recipient

, P = 0.009; HA: P = 0.01), according to time since LT (> than 5 years, TFG-β1: P = 0.001; HA: P = 0.002), related to previous history of biliary complications (HA: P = 0.01) and HCV recurrence (HA: P = 0.004). Liver transplant recipients with everolimus monotherapy had less serum expression of TGF-β y HA than matched patients with anti-calcineurins. This difference remains when classifying patients according to donor age and time since LT. Due to the small sample size, when examining patients with a prior history of biliary complications or recurrent HCV, the difference was non-significant but trends towards the lower expression of TFG-β1 in the everolimus group. Mammalian target of rapamycin (mTOR) plays a role in the transformation of quiescent hepatocellular stellate cell to their active profibrotic state, and experimental models have demonstrated the potential activity of mTOR inhibition in attenuating fibrogenesis. This study supports a possible role of everolimus in liver fibrosis modulation after LT in a clinical setting and suggests that tailoring immunosuppression could avoid fibrosis progression in the allograft.

Fractures are associated with high morbidity and are a major concern for kidney transplant recipients. No comparative analysis has yet been conducted between countries in the contemporary era to inform future international prevention trials. Data were obtained from the Hospital Episode Statistics and the Statewide Planning and Research Cooperative databases on all adult kidney transplants performed in England and New York State from 2003 to 2013, respectively, and on posttransplant fracture-related hospitalization from 2003 to 2014. Our analysis included 18 493 English and 11 602 New York State kidney transplant recipients. Overall, 637 English recipients (3.4%) and 398 New York State recipients (3.4%) sustained a fracture, giving an unadjusted event rate of 7.0 and 5.9 per 1000 years, respectively (P = .948). Of these, 147 English (0.8%) and 101 New York State recipients (0.9%) sustained a hip fracture, giving an unadjusted event rate of 1.6 and 1.5 per 1000 years, respectively (P = .480). There were no differences in the cumulative incidence of all fractures or hip fractures. One-year mortality rates after any fracture (9% and 11%) or after a hip fracture (15% and 17%) were not different between cohorts. Contemporaneous English and New York State kidney transplant recipients have similar fracture rates and mortality rates postfracture.

Vascular closure devices are used to provide quick hemostasis and early ambulation after percutaneous interventions. The Angio-Seal (AS) vascular closure device forms a mechanical seal by closing the puncture site located between a bioabsorbable anchor within the lumen and a collagen sponge on the adventitia. Although morbidities associated with AS are reportedly infrequent, even the slightest inaccuracy in device implantation may result in displacement of these device components, leading to sudden and severe complications. We report the surgical treatment of complications associated with the use of AS in four patients, including acute limb ischemia, pseudoaneurysm formation, significant hemorrhage, and hypovolemic shock. A common factor in all these cases was that the components of the AS device were displaced from their original site of implantation, stressing the importance of proper device placement. All patients underwent successful surgical vascular repair. Our report highlights the need for exercising extreme care during device implantation, and also the requirement for vigilant inspection for any associated vascular complications commencing immediately after device implantation. It is vital that these device components are actively looked for and removed during surgical exploration so as to prevent future complications. Copyright © 2011. Published by Elsevier Inc.

The association between religiousness and children's altruism: The role of the recipient's neediness.

Sabato, Hagit; Kogut, Tehila

We examined the role of the recipient's neediness as a moderator in the relation between children's household religiosity and prosocial behavior. Examining the behavior of children (2nd and 5th graders) from religious and nonreligious households in the dictator game, we found that the extent of sharing did not differ significantly between the 2 groups when the recipient was not described as needy. However, when the recipient was presented as a poor (needy) child, the religious group exhibited significantly more sharing behavior. Although the religious children's tendency to share more with needy recipients compared with the not-needy ones appeared already in the 2nd grade, it increased with age as children grew and internalized the norms of their immediate society. Among the major religions, the recipient's neediness is an important variable in the decision to give, which shapes religious children's prosocial behavior from an early age. Thus, future research should take this moderator into account when studying the relation between religiousness and prosociality in general and in the development of prosociality in children in particular.

Asymptomatic malaria parasitaemia has been documented in donor blood in West Africa. However, donated blood is not routinely screened for malaria parasites (MPs). The present study therefore aimed to document the frequency of blood transfusion-induced donor-recipient malaria parasitaemia patterns, in children receiving blood transfusion in a tertiary health-centre. A cross-sectional, observational study involving 140 children receiving blood transfusion was carried out. Blood donor units and patients' blood samples were obtained, for the determination of malaria parasites (MPs). Giemsa staining technique was used to determine the presence of malaria parasitaemia. Malaria parasites were detected in 7% of donor blood and in 8.3% of the recipients' pretransfusion blood. The incidence of posttransfusion MPs was 3%, but none of these were consistent with blood transfusion-induced malaria, as no child with posttransfusion parasitaemia was transfused with parasitized donor blood. Majority of the blood transfusions (89.4%) had no MPs in either donors or recipients, while 6.8% had MPs in both donors and recipients, with the remaining 3.8% showing MPs in recipients alone. In conclusion, the incidence of posttransfusion malaria parasitaemia appears low under the prevailing circumstances.

Regeneration dynamics in bone marrow and spleen was studied in rats after irradiation of 800 R and transfusion of bone marrow cells from donors treated in different ways. Priority of the microenvironment of the recipient or of the information obtained in cell donors with respect to further hematopoietic cell differentiation was studied in irradiated recipients. Rats irradiated with 800 R were used as recipients in the experiments. The donors of marrow cells were the rats with stimulated or inhibited erythropoiesis. Stimulation of erythropoiesis was induced by bleeding and experimental polycythemia was provoked by packed erythrocytes. According to our results, it can be concluded that the processes of postirradiation hematopoiesis after transplantation of the bone marrow cells depend on the number and proliferative state of both donors and recipient stem cells, and microenvironment, not excluding the information introduced with the donor cell transplant.

Background The Recipient Epidemiology and Donor Evaluation Study -III (REDS-III) is a 7-year multicenter transfusion safety research initiative launched in 2011 by the National Heart, Lung, and Blood Institute. Study design The domestic component involves 4 blood centers, 12 hospitals, a data coordinating center, and a central laboratory. The international component consists of distinct programs in Brazil, China, and South Africa which involve US and in-country investigators. Results REDS-III is using two major methods to address key research priorities in blood banking/transfusion medicine. First, there will be numerous analyses of large “core” databases; the international programs have each constructed a donor/donation database while the domestic program has established a detailed research database that links data from blood donors and their donations, the components made from these donations, and data extracts from the electronic medical records of the recipients of these components. Secondly, there are more than 25 focused research protocols involving transfusion recipients, blood donors, or both that are either in progress or scheduled to begin within the next 3 years. Areas of study include transfusion epidemiology and blood utilization; transfusion outcomes; non-infectious transfusion risks; HIV-related safety issues (particularly in the international programs); emerging infectious agents; blood component quality; donor health and safety; and other donor issues. Conclusions It is intended that REDS-III serve as an impetus for more widespread recipient and linked donor-recipient research in the US as well as to help assure a safe and available blood supply in the US and in international locations.

Adult cochlear implant (CI) recipients demonstrate a reliable relationship between spectral modulation detection and speech understanding. Prior studies documenting this relationship have focused on postlingually deafened adult CI recipients-leaving an open question regarding the relationship between spectral resolution and speech understanding for adults and children with prelingual onset of deafness. Here, we report CI performance on the measures of speech recognition and spectral modulation detection for 578 CI recipients including 477 postlingual adults, 65 prelingual adults, and 36 prelingual pediatric CI users. The results demonstrated a significant correlation between spectral modulation detection and various measures of speech understanding for 542 adult CI recipients. For 36 pediatric CI recipients, however, there was no significant correlation between spectral modulation detection and speech understanding in quiet or in noise nor was spectral modulation detection significantly correlated with listener age or age at implantation. These findings suggest that pediatric CI recipients might not depend upon spectral resolution for speech understanding in the same manner as adult CI recipients. It is possible that pediatric CI users are making use of different cues, such as those contained within the temporal envelope, to achieve high levels of speech understanding. Further investigation is warranted to investigate the relationship between spectral and temporal resolution and speech recognition to describe the underlying mechanisms driving peripheral auditory processing in pediatric CI users.

Full Text Available Purpose: While brachytherapy is often used concurrently with flap reconstruction following surgical ablation for head and neck cancer, it remains unclear whether it increases morbidity in the particularly high risk subset of patients undergoing salvage treatment for recurrent head and neck cancer (RH&NC. Material and methods : A retrospective chart review was undertaken that evaluated patients with RH&NC who underwent flap coverage after surgical re-resection and concomitant brachytherapy. The primary endpoint was flap viability, and the secondary endpoints were flap and recipient site complications. Results : In the 23 subjects included in series, flap viability and skin graft take was 100%. Overall recipient site complication rate was 34.8%, high-dose radiation (HDR group 50%, and low-dose radiation (LDR group 29.4%. There was no statistically significant difference between these groups. Conclusions : In patients who undergo flap reconstruction and immediate postoperative radiotherapy following salvage procedures for RH&NC, flap coverage of defects in combination with brachytherapy remains a safe and effective means of providing stable soft tissue coverage.

The growing need for organs and the scarcity of donors has resulted in an increased use of extended criteria donors. We report a case where a recipient of a cardiac graft was used as an organ donor. Death of the recipient occurred 9 days after transplantation and was attributed to presumed cerebral hemorrhage, which post mortem was diagnosed as invasive aspergillosis of the brain. One recipient of a kidney transplant lost the graft due to infection with Aspergillus fumigatus, whereas prompt initiation of therapy successfully prevented disseminated aspergillosis in the other recipients. Despite the pressure to extend the use of organs by lowering the acceptance criteria, organs should only be accepted if the cause of death of the donors is unequivocally explained.

Donors and Recipients of Living Kidney Donation: A Qualitative Metasummary of Their Experiences

Deborah Ummel

2011-01-01

Full Text Available With the notable growth in the qualitative investigation of living kidney donation, there is value in aggregating results from this body of research to learn from accumulated experience. The present paper aims to draw a complete portrait of living donors' and recipients' experience of donation by metasummarizing published studies. We found that donors' experience, particularly the decision-making process, has been more extensively studied than the recipients' perspective. Donors differ in their initial level of motivation to donate but on the whole report positive experiences and personal benefits. They also identify difficult periods and the need for additional resources. Recipients report an often positive but more ambivalent reaction to donation. In terms of relational issues between dyads, while the topic remains understudied, the donor-recipient relationship and gift reciprocity have received the most attention. Results are discussed in terms of their implications for future practice and research.

Graft-Versus-Host Disease after Liver Transplantation Complicated by Systemic Aspergillosis with Pancarditis

Directory of Open Access Journals (Sweden)

Joseph Romagnuolo

2000-01-01

Full Text Available Acute graft-versus-host disease (GVHD is a common complication after bone marrow transplantation, with characteristic rash and diarrhea being the most common features. After liver transplantation, however, this phenomenon is very rare. Most transplant patients are on a variety of medications, including immunosuppressants; therefore, the differential diagnosis of skin rash or diarrhea is broad. A 37-year-old man who underwent liver transplantation for primary biliary cirrhosis, and developed a rash and watery diarrhea, is presented. Skin and colonic biopsies confirmed acute GVHD. A pulse of intravenous steroids was given. The skin rash improved, but he developed pancytopenia. His course was complicated by central line infection, jugular and subclavian vein thrombosis, pseudomembranous colitis, recurrent bacteremia, cholestasis on total parenteral nutrition and cytomegalovirus infection. After the onset of pleuritic chest pain and clinical sepsis, spiral computed tomography scan of his chest and abdomen revealed septic infarcts in multiple organs. Despite empirical treatment with amphotericin B, he died of multiorgan dysfunction syndrome within 72 h. Autopsy revealed systemic aspergillosis with pancarditis, endocardial vegetations, and septic pulmonary, splenic, hepatic and renal infarcts. The pathogenesis and experience with this rare, but often fatal, complication of liver transplantation are reviewed. In contrast to GVHD after bone marrow transplantation, pancytopenia is common and liver dysfunction is rare. One should have a high level of suspicion in the liver transplant recipient presenting with rash and/or diarrhea.

Most respiratory syncytial virus (RSV) vaccine candidates include fusion (F) protein in different conformations. Antigenic site II found in the different F conformations is the target of palivizumab, the only US Food and Drug Administration approved monoclonal antibody (mAb). Serum palivizumab-like antibody (PLA) is a potential serologic correlate of immunity. Our objective was to determine if different conformations of F protein in a palivizumab competitive antibody (PCA) assay affect the PLA concentrations. Four PCA assays were standardized using mAbs. Each contained prefusion, postfusion, or intermediate F forms. PLA concentrations were measured in acute and convalescent sera from 22 RSV/A and 18 RSV/B-infected adult hematopoietic cell transplant (HCT) recipients. PLA concentrations were calculated using a 4-parameter logistic regression model and analyzed for statistical significance. PCA assays revealed significantly greater PLA concentrations in convalescent sera; comparable increases in PLA concentration in RSV/A and RSV/B-infected HCT recipients; and significantly reduced PLA concentrations in HCT recipients who shed RSV ≥14 days. A significant positive correlation was observed between PCA assays and RSV neutralizing antibody titers. F protein conformation does not appear to have a measurable impact on PCA assays for measuring PLA induced by RSV/A or RSV/B infection.

2018-04-01

Full Text Available ABSTRACT Objective: to identify predictors of chest drainage complications in trauma patients attended at a University Hospital. Methods: we conducted a retrospective study of 68 patients submitted to thoracic drainage after trauma, in a one-year period. We analyzed gender, age, trauma mechanism, trauma indices, thoracic and associated lesions, environment in which the procedure was performed, drainage time, experience of the performer, complications and evolution. Results: the mean age of the patients was 35 years and the male gender was the most prevalent (89%. Blunt trauma was the most frequent, with 67% of cases, and of these, 50% were due to traffic accidents. The mean TRISS (Trauma and Injury Severity Score was 98, with a mortality rate of 1.4%. The most frequent thoracic and associated lesions were, respectively, rib fractures (51% and abdominal trauma (32%. The mean drainage time was 6.93 days, being higher in patients under mechanical ventilation (p=0.0163. The complication rate was 26.5%, mainly poor drain positioning (11.77%. Hospital drainage was performed in 89% of cases by doctors in the first year of specialization. Thoracic drainage performed in prehospital care presented nine times more chances of complications (p=0.0015. Conclusion: the predictors of post-trauma complications for chest drainage were a procedure performed in an adverse site and mechanical ventilation. The high rate of complications demonstrates the importance of protocols of care with the thoracic drainage.

Malignancy following renal transplantation remains inconsistent with the reported safety of kidney donation during the long-term follow-up. We conducted searches of the published literature which included healthy participants, recipients, living kidney donors (LKDs), and the availability of outcome data for malignancy. Eight from 938 potentially relevant studies were analyzed by means of fixed-effects model or random-effects model, as appropriately. In 48,950 participants, the follow-up range was 18 months to 20 years, and the mean age of the subjects was approximately 41 years. The incidence rate with 95% confidence interval (CI) for malignancy after kidney transplantation was 0.03 (0.01-0.05) in recipients and 0.03 (0.1-0.07) in LKDs, giving a pooled incidence rate of 0.03 (95% CI 0.02-0.04). LKDs contrasted nondonors by the overall odds ratio and 95% CI for total cancer of 2.80 (2.69-2.92). Kidney transplantation was associated with an increased risk of cancer during a long-term follow-up. Long-term risk for cancer in LKDs and kidney recipients should be monitored.

Critical care of the hematopoietic stem cell transplant recipient.

An estimated 50,000 to 60,000 patients undergo hematopoietic stem cell transplantation (HSCT) worldwide annually, of which 15.7% are admitted to the intensive care unit (ICU). The most common reason for ICU admission is respiratory failure and almost all develop single or multiorgan failure. Most HSCT recipients admitted to ICU receive invasive mechanical ventilation (MV). The overall short-term mortality rate of HSCT recipients admitted to ICU is 65%, and 86.4% for those receiving MV. Patient outcome has improved over time. Poor prognostic indicators include advanced age, poor functional status, active disease at transplant, allogeneic transplant, the severity of acute illness, and the development of multiorgan failure. ICU resource limitations often lead to triage decisions for admission. For HSCT recipients, the authors recommend (1) ICU admission for full support during their pre-engraftment period and when there is no evidence of disease recurrence; (2) no ICU admission for patients who refuse it and those who are bedridden with disease recurrence and without treatment options except palliation; (3) a trial ICU admission for patients with unknown status of disease recurrence with available treatment options.

Recent evidence suggests that fibromyalgia syndrome (FS) is associated with inflammation and endothelial dysfunction. Our aim was to determine the prevalence of FS in renal transplant recipients and to identify possible links between FS and clinical and laboratory parameters. Ninety-nine kidney transplant recipients with normal graft functions (37.15 ± 10.83 years old, 67 male) were enrolled in the study. All subjects completed the Fibromyalgia Impact Questionnaire (FIQ). The biochemical and clinical parameters in the 1st post-transplantation year were retrospectively recorded. Cardiovascular parameters, including body composition analyses (Tanita), ambulatory blood pressure monitoring data, and pulse-wave velocity, were cross-sectionally analyzed. Mean FIQ score for the whole group was 21.4 ± 14.7. Eight patients had FIQ score >50, and these patients had significantly higher left ventricular mass index than patients with lower FIQ score (P = .048). Patients were divided according to their physical impairment score (PIS): PIS ≥5 (n = 50) and PIS FIQ (7.6% vs 9.4%; P = .0001) than in other patients. FS in renal transplant recipients was strongly associated with hypertension, arterial stiffness, obesity, and renal allograft dysfunction. Copyright © 2015 Elsevier Inc. All rights reserved.

Immune reconstitution following hematopoietic stem cell transplantation (HSCT) is critical in preventing harmful sequelae in recipients with cytomegalovirus (CMV) infection. To understand the molecular mechanisms underlying immune reconstitution kinetics, we profiled the transcriptome-chromatin accessibility landscape of CMV-specific CD8 + T cells from HCST recipients with different immune reconstitution efficiencies. CMV-specific T cells from HSCT recipients with stable antiviral immunity expressed higher levels of interferon/defense response and cell cycle genes in an interconnected network involving PI3KCG , STAT5B , NFAT , RBPJ , and lower HDAC6 , increasing chromatin accessibility at the enhancer regions of immune and T-cell receptor signaling pathway genes. By contrast, the transcriptional and epigenomic signatures of CMV-specific T cells from HSCT recipients with unstable immune reconstitution showed commonalities with T-cell responses in other nonresolving chronic infections. These signatures included higher levels of EGR and KLF factors that, along with lower JARID2 expression, maintained higher accessibility at promoter and CpG-rich regions of genes associated with apoptosis. Furthermore, epigenetic targeting via inhibition of HDAC6 or JARID2 enhanced the transcription of genes associated with differential responses, suggesting that drugs targeting epigenomic modifiers may have therapeutic potential for enhancing immune reconstitution in HSCT recipients. Taken together, these analyses demonstrate that transcription factors and chromatin modulators create different chromatin accessibility landscapes in T cells of HSCT recipients that not only affect immediate gene expression but also differentially prime cells for responses to additional signals. Epigenetic therapy may be a promising strategy to promote immune reconstitution in HSCT recipients. © 2018 by The American Society of Hematology.

Obesity, in the either kidney donor or the recipient, has been related to worse graft function. The aim of this study was to compare long-term graft outcomes of living-related kidney recipients regarding the donor-to-recipient body mass index (BMI) ratio. From November 2002 to November 2010, 62 consecutive living-related kidney transplantations were performed at our center. Donor and recipient BMIs were categorized by Taiwan's national standard using dividing values of 18.5, 24, and 27 kg/m(2) to divide subjects into donor-to-recipient BMI categories. These with the same BMI category as their donors were defined as the same-BMI group (group 0); recipients with a lower BMI category than their donors were defined as the large-to-small group (group 1); and those with a higher BMI category than their donors were defined as the small-to-large group (group 2). Baseline parameters and posttransplantation follow-up data were analyzed according to this grouping. Of the 57 recipients followed regularly at our hospital (mean follow-up 48.9 months), 21 (36.8.1%) were in group 0; 26 (45.6%) in group 1, and 10 (17.6%) in group 2. The baseline parameters were similar among these groups. The overall graft survival rates were 81.0% in group 0, 76.9% in group 1, and 90.0% in group 2. The rejection-free graft survival rates were 81.0%, 65.4%, and 90.0%, respectively. By Kaplan-Meier analysis, group 1 showed worse rejection-free graft survival than group 0 or group 2 (log-rank P = .046). Living-related recipients of kidneys from donors with a higher BMI showed lower long-term graft survival, which might suggest that petite recipients may need time to compensate adequate blood flow for the relative large graft, thus carrying a higher chance of rejection and worse graft outcomes.

In order to evaluate glucose tolerance following renal transplantation, intravenous glucose tolerance tests (IVGTT), with evaluation of hormonal responses to the intravenous glucose load and percent specific 125 I-insulin binding to peripheral blood monocytes, were studied in eight clinically stable kidney transplant recipients. For comparison purposes, identical studies were done in eight control subjects and seven clinically stable hemodialysis patients. One transplant recipient was glucose intolerant, with fasting hyperglycemia, elevated HbA1C, and abnormal glucose decay constant. Impaired pancreatic insulin release appeared to be the major factor accounting for his glucose intolerance. The seven glucose-tolerant transplant recipients had significantly increased insulin release during IVGTT compared to control subjects, and significant correlations were found among insulin release, glucose decay constant, and fasting blood sugar in those patients. Insulin binding to monocytes was significantly greater in transplant recipients than control subjects due to an increase in insulin binding capacity per cell. A significant correlation was found between percent specific 125 I-insulin binding and steroid dose, expressed as mg/kg body weight/day, in those patients. Thus, chronic steroid administration does not cause glucose intolerance in transplant recipients who manifest steroid-associated increases in pancreatic insulin release and cellular insulin binding capacity

End-stage kidney disease is a life-threatening condition that compels patients to accept either dialysis or transplant. Kidney transplantation is the best choice for patients with end-stage kidney disease because it ensures higher quality of life and longer survival rates than other choices, with less cost for the healthcare system. However, in order for renal recipients to maintain the functioning graft they must take lifelong immunosuppressive medications, with possible side effects and low medication adherence. It is known that low medication adherence in kidney transplant recipients may cause poor outcomes, chronic graft rejection, and graft failure. In this review, the authors give an overview of nonadherence in the transplant setting. In addition, they analyze the role of different technologies as an aid to improve adherence, with a focus on mobile-phone based solutions to monitor and enhance kidney transplant recipient compliance.

Backgrounds and aims: Accurate assessment of graft bile duct is important to plan surgical procedure. Magnetic resonance cholangiopancreatography (MRCP) has become an important diagnostic procedure in evaluation of pancreaticobiliary ductal abnormalities and has been reported as highly accurate. We aim to estimate the efficacy of preoperative MRCP on depicting biliary anatomy in living donor liver transplantation (LDLT), and to determine whether inaccurate preoperative imaging assessment would increase the biliary complications after LDLT. Methods: The data of 118 cases LDLT were recorded. Information from preoperative MRCP was assessed using intraoperative cholangiography (IOC) as the gold standard. The possible risk factors of recipient biliary complications were analyzed. Results: Of 118 donors, 84 had normal anatomy (type A) and 34 had anatomic variants (19 cases of type B, 9 cases of type C, 1 case of type E, 2 cases of type F and 3 cases of type I) confirmed by IOC. MRCP correctly predicted all 84 normal cases and 17 of 34 variant cases, and showed an accuracy of 85.6% (101/118). The incidence of biliary complications was comparable between cases with accurate and inaccurate classification of biliary tree from MRCP, and between cases with normal and variant anatomy of bile duct. While cases with graft duct opening ≤5 mm showed a significant higher incidence of total biliary complications (21.1% vs. 6.6%, P = 0.028) and biliary stricture (10.5% vs. 1.6%, P = 0.041) compared with cases with large duct opening >5 mm. Conclusion: MRCP could correctly predict normal but not variant biliary anatomy. Inaccurate assessment of biliary anatomy from MRCP not increases the rate of biliary complications, while small-sized graft duct may cause an increase in biliary complications particularly biliary stricture after LDLT.

Correlation Between Resonance Frequency Analysis and Bone Quality Assessments at Dental Implant Recipient Sites.

Fu, Min-Wen; Fu, Earl; Lin, Fu-Gong; Chang, Wei-Jeng; Hsieh, Yao-Dung; Shen, E-Chin

To evaluate whether primary implant stability could be used to predict bone quality, the association between the implant stability quotient (ISQ) value and the bone type at the implant site was evaluated. Ninety-five implant sites in 50 patients were included. Bone type (categorized by Lekholm and Zarb) at the implant site was initially assessed using presurgical dental radiography. During the preparation of the implant site, a bone core specimen was carefully obtained. The bone type was assessed by tactile sensation during the drilling operation, according to the Misch criteria. The primary stability of the inserted implant was evaluated by resonance frequency analysis (RFA). The ISQ value was recorded. The bone core specimen was then examined by stereomicroscopy or microcomputed tomography (micro-CT), and the bone type was determined by the surface characteristics of the specimen, based on Lekholm and Zarb classification. Agreement between the bone quality assessed by the four methods (ie, presurgical radiography, tactile sensation, stereomicroscopy, and micro-CT) was tested by Cohen's kappa statistics, whereas the association between the ISQ value and the bone type was evaluated by the generalized linear regression model. The mean ISQ score was 72.6, and the score was significantly influenced by the maxillary or mandibular arch (P = .001). The bone type at the implant sites varied according to the assessment method. However, a significant influence of the arch was repeatedly noted when using radiography or tactile sensation. Among the four bone-quality assessment methods, a weak agreement existed only between stereomicroscopy and micro-CT, especially in the maxilla (κ = 0.469). A negative association between the ISQ value and the bone type assessed by stereomicroscopy or by micro-CT was significant in the maxilla, but not in the mandible, after adjustments for sex, age, and right/left side (P = .013 and P = .027 for stereomicroscopy and micro-CT, respectively

Full Text Available Freedom from pain has almost developed to be a fundamental human right. Providing pain relief via epidural catheters in thoracic and upper abdominal surgeries is widely accepted. Pain relief through this technique not only provides continuous analgesia but also reduces post-operative pulmonary complications and also hastens recovery. But being a blind procedure it is accompanied by certain complications. Hypotension, dura puncture, high epidural, total spinal, epidural haematoma, spinal cord injury and infection are some of the documented side effects of epidural block. There are case reports eliciting neurological complications, catheter site infections, paresthesias, radicular symptoms and worsening of previous neurological conditions. Few technical problems related to breakage of epidural catheter are also mentioned in the literature. The patient had no sequelae on long term follow up even when a portion of catheter was retained. We present a case report where epidural catheter punctured pleura in a patient undergoing thoracotomy for carcinoma oesophagus.

To determine the prevalence of (very) low food security among Dutch food bank recipients, and to identify potential demographic, lifestyle and nutrition-related factors associated with (very) low food security. 11 of 135 Dutch food banks were selected throughout the Netherlands. 251 Dutch food bank recipients participated in the study (93 men and 158 women). Inclusion criteria for participation were: (1) at least 18 years of age, (2) sufficiently fluent in Dutch to participate in oral and written interviews, (3) recipient of a Dutch food bank for at least 1 month and (4) collect own food parcel at the food bank. A single member per household was included. Level of food security. The prevalence of food insecurity was 72.9% (N=183), of which 40.4% (N=74) reported very low food security. Of the very low food secure participants, 56.8% (N=42) reported they were ever hungry but did not eat because they could not afford enough food in the previous 3 months. Adjusted multinomial logistic regression analyses showed that households without children were less likely to experience low food security (OR 0.39 (95% CI 0.18 to 0.88)) and men (OR 0.24 (95% CI 0.11 to 0.51)) were less likely to experience very low food security, while low-educated recipients (OR 5.05 (95% CI 1.37 to 18.61)) were more likely to experience very low food security. Furthermore, recipients with high satisfaction with overall food intake (OR 0.46 (95% CI 0.27 to 0.78)), high perceived healthiness of overall food intake (OR 0.34 (95% CI 0.19 to 0.62)) or high self-efficacy of eating healthy (OR 0.62 (95% CI 0.40 to 0.96)) were less likely to experience very low food security. Our study showed high prevalence rates of food insecurity among Dutch food bank recipients, and identified subgroups at increased risk of food insecurity. More research is urgently needed on the underlying determinants of food insecurity and the effectiveness of food assistance by food banks. Published by the BMJ Publishing

The purposes of this study were (a) to compare recognition of "real-world" music excerpts by postlingually deafened adults using cochlear implants and normal-hearing adults; (b) to compare the performance of cochlear implant recipients using different devices and processing strategies; and (c) to examine the variability among implant recipients in recognition of musical selections in relation to performance on speech perception tests, performance on cognitive tests, and demographic variables. Seventy-nine cochlear implant users and 30 normal-hearing adults were tested on open-set recognition of systematically selected excerpts from musical recordings heard in real life. The recognition accuracy of the two groups was compared for three musical genre: classical, country, and pop. Recognition accuracy was correlated with speech recognition scores, cognitive measures, and demographic measures, including musical background. Cochlear implant recipients were significantly less accurate in recognition of previously familiar (known before hearing loss) musical excerpts than normal-hearing adults (p genre. Implant recipients were most accurate in the recognition of country items and least accurate in the recognition of classical items. There were no significant differences among implant recipients due to implant type (Nucleus, Clarion, or Ineraid), or programming strategy (SPEAK, CIS, or ACE). For cochlear implant recipients, correlations between melody recognition and other measures were moderate to weak in strength; those with statistically significant correlations included age at time of testing (negatively correlated), performance on selected speech perception tests, and the amount of focused music listening following implantation. Current-day cochlear implants are not effective in transmitting several key structural features (i.e., pitch, harmony, timbral blends) of music essential to open-set recognition of well-known musical selections. Consequently, implant

Our aim was to evaluate the influence of the localization of right posterior bile duct anatomy relative to portal vein of the donors on posttransplant bile duct complications. We retrospectively investigated 141 patients who had undergone living donor liver transplant using right hemiliver grafts. The patients were classified based on the pattern of the right posterior bile duct and divided into infraportal and supraportal types. Clinical donor and recipient risk factors and surgical outcomes were compared for their relationship with biliary complications using logistic regression analyses. The 2 groups were similar according to demographic and clinical features. The biliary complication rate was 23.7% (9/38) in the infraportal group and 47.4% (37/78) in the supraportal group (P = .014). An analysis of risk factors for the development of anastomotic bile leak using logistic regression showed that a supraportal right posterior bile duct anatomy was a statistically significant positive predictor, with odds ratio of 18.905 (P = .012; confidence interval, 1.922-185.967). The distance of the right posterior bile duct from confluence was significantly lower in patients with biliary complications than in those without (mean of 7.66 vs 0.40 mm; P = .044). According to receiver operating characteristic analyses, the cut-off point for the length of right bile duct to right posterior bile duct from the hepatic confluence was 9.5 mm regarding presence of complications. Factors influencing bile duct anastomosis leakage were supraportal-type donor bile duct anatomy and length of the right main bile duct from biliary confluence. Hepatic arterial complications were similarly a risk factor for biliary strictures. Because of the multiple factors leading to complications in living donor liver transplant, it is challenging to group these patients by operative risk; however, establishing risk models may facilitate the prediction of complications.

Parvovirus B19 is a DNA virus that is responsible for causing several diseases in humans. Parvovirus B19-induced persistent anemia is one of its manifestations that is relatively common in transplant recipients. This study was aimed to investigate the seroprevalence of parvovirus B19 among kidney transplant recipients. Ninety-one transplant recipients were selected randomly and were investigated for several variables including age, gender, educational status, history of hemodialysis (HD), history of blood transfusion and immunosuppressive therapy. Two milliliters of blood samples were collected via venipuncture and evaluated for anti-Parvovirus B19 IgG antibody using enzyme-linked immunosorbent assay. All recipients were anemic, with 72.5% of them suffering from severe anemia (Hb ≤ 11 in men and ≤ 10 in women). Sixty-three patients (69.2%) were seropositive for Parvovirus B19. There was no significant difference in age, sex, educational status, history of blood transfusion, history of HD and immunosuppressive therapy between seropositive and seronegative groups. The seroprevalence of Parvovirus B19 was relatively high in kidney transplant recipients in Urmia, Iran. Our study failed to find a correlation between the severity of anemia and the seropositivity of Parvovirus B19.

Self-care behaviors are crucial for following the complex regimen after lung transplantation, yet little is known about recipients' levels of self-care agency (the capability and willingness to engage in self-care behaviors) and its correlates. We examined levels of self-care agency and recipient characteristics (socio-demographics, psychological distress, quality of relationship with primary lay caregiver, and health locus of control) in 111 recipients. Based on Perceived Self-Care Agency scores, recipients were assigned to either the low- or high-self-care agency comparison group. Characteristics were compared between groups to identify characteristics likely to be associated with lower-self-care agency. Mean (SD) score for self-care agency (scale range, 53-265) was 223.02 (22.46). Recipients with lowest-self-care agency scores reported significantly poorer quality of caregiver relationships (p recipient-caregiver relationship remained significantly associated with self-care agency. Every one-point decrease in the quality of caregiver relationship increased the risk of low-self-care agency by 12%. Recipients with poorer caregiver relationships and greater psychological distress may need additional support to perform the self-care behaviors expected after lung transplantation. © 2012 John Wiley & Sons A/S.

Introduction Blood transfusion has health-related, economical and safety implications. In order to optimise the transfusion chain, comprehensive research data are needed. The Dutch Transfusion Data warehouse (DTD) project aims to establish a data warehouse where data from donors and transfusion recipients are linked. This paper describes the design of the data warehouse, challenges and illustrative applications. Study design and methods Quantitative data on blood donors (eg, age, blood group, antibodies) and products (type of product, processing, storage time) are obtained from the national blood bank. These are linked to data on the transfusion recipients (eg, transfusions administered, patient diagnosis, surgical procedures, laboratory parameters), which are extracted from hospital electronic health records. Applications Expected scientific contributions are illustrated for 4 applications: determine risk factors, predict blood use, benchmark blood use and optimise process efficiency. For each application, examples of research questions are given and analyses planned. Conclusions The DTD project aims to build a national, continuously updated transfusion data warehouse. These data have a wide range of applications, on the donor/production side, recipient studies on blood usage and benchmarking and donor–recipient studies, which ultimately can contribute to the efficiency and safety of blood transfusion.

Immunosuppressive treatment used in pregnant liver recipients may have a negative impact on fetal development and successively a child. The aim of the study was to make a neurological assessment of infants and children born to liver transplant recipients (LTRs) born between December 4, 2001, and February 11, 2013, in the 1(st) Department of Obstetrics and Gynecology, Medical University of Warsaw. The study involved 88 children, of whom 44 children were born to LTR mothers, and 44 children born to women who were not organ recipients and delivered at a similar gestational age. The gestational age of neonates ranged from 33 to 41 weeks, and the birth weight ranged from 1420 g to 4100 g. The neurological examination was performed in children from 7 weeks to 10 years of age. The neurological development was assessed by a specialist in pediatric neurology. The results of the examination were divided according to the following criteria: 1) normal development, 2) slight disorders, 3) moderate disorders, and 4) severe disorders. The Fisher's exact test was used for statistical analysis. Normal development was found in 35 of 44 (79.54%) children in the LTR group and 39 of 44 (88.63%) children in the control group (P = .3827). Slight disorders were observed in 6 of 44 (13.63%) children in LTR group and 5 of 44 (11.36%) children in the control group. Moderate disorders were found only in 3 of 44 (6.81%) children in the LTR group. No severe disorders were observed in both groups. Neurological development of children born to the liver recipients who were exposed to chronic immunosuppressive treatment in their fetal lives is the same as that of children whose mothers have not undergone organ transplantation.

BK polyomavirus infection and de novo donor-human leukocyte antigen (HLA) specific antibodies (dnDSA) are two well-known and distinct complications occurring after kidney transplantation. Recent literature suggests an association between the two events. This study aims to examine the relationship between BK viremia (BKV) and dnDSA and to identify potential risk factors for dnDSA following BKV in kidney transplant recipients. A retrospective review of 1019 recipients from Houston Methodist Hospital was conducted. All patients underwent routine screening for BKV and dnDSA. Median follow-up was 44 months. BKV was detected in 186 (18%) patients at a median of 107 (82-205) days post-transplant. dnDSA occurred in 283 (28%) patients at a median of 272 (62-575) days post-transplant. Of the 69 dnDSA-positive/BKV-positive patients, dnDSA detection occurred after BKV onset in 46 patients. Thus, 46 (28%) previously DSA-negative patients later became dnDSA-positive following BKV, not significantly different from the rate seen in BKV-negative patients (26%; p=0.5). Median time to DSA detection following BKV onset was 232 days (interquartile range, 119-460) post-BKV detection. Multivariate analysis revealed a greater number of HLA mismatches and viral clearance as risk factors for development of dnDSA following BKV, whereas delayed graft function was associated with a lower risk of dnDSA. In conclusion, despite being considered a result of over-immunosuppression, BKV can still be followed by dnDSA in a substantial proportion of patients. Monitoring for dnDSA in patients being managed for BKV may be warranted. Copyright© 2017 by the Terasaki Research Institute.

Solid organ transplant (SOT) recipients are often heavily immunosuppressed and consequently at risk of serious illness from vaccine preventable viral and bacterial infections or with endemic fungal and parasitic infections. We review the literature to provide guidance regarding the timing and appropriateness of vaccination and pathogen avoidance related to the immunological status of SOT recipients. A PUBMED search ([Vaccination OR vaccine] AND/OR ["specific vaccine"] AND/OR [immunology OR immune response OR cytokine OR T lymphocyte] AND transplant was performed. A review of the literature was performed in order to develop recommendations on vaccination for SOT recipients travelling to high-risk destinations. Whilst immunological failure of vaccination in SOT is primarily the result of impaired B-cell responses, the role of T-cells in vaccine failure and success remains unknown. Vaccination should be initiated at least 4 weeks prior to SOT or more than 6 months post-SOT. Avoidance of live vaccination is generally recommended, although some live vaccines may be considered in the specific situations (e.g. yellow fever). The practicing physician requires a detailed understanding of region-specific endemic pathogen risks. We provide a vaccination and endemic pathogen guide for physicians and travel clinics involved in the care of SOT recipients. In addition, recommendations based on timing of anticipated immunological recovery and available evidence regarding vaccine immunogenicity in SOT recipients are provided to help guide pre-travel consultations. © International Society of Travel Medicine, 2016.

To analyze the complications of first 400 laparoscopic cholecystectomies (LC) for patients with symptomatic gall stone disease at a tertiary care hospital. Study Design: Quasi-experimental study. Place and Duration of Study: PNS Shifa Karachi and CMH Lahore, Pakistan from Nov 2009 to Jan 2013. Patients and Methods: A prospective analysis of complications occurring in first 400 consecutive laparoscopic cholecystectomies by a single consultant/unit at a tertiary care hospital was made. Out of total 421 patients presenting with symptomatic gall stone disease in a single unit, 21 cases that underwent open cholecystectomy were excluded from the study. Laparoscopic cholecystectomies were performed using three port and four port technique and data including age, sex, diagnosis, number of trocar placements, conversion to open surgery and its reasons, operative time, post-operative hospital stay and complications was collected on personal computer and analyzed using Statistical package for social sciences (SPSS) version 13. Results: Total 400 patients were included in study with median age of 44 years. Female to male ratio was 5.3: 1. Depending upon the preoperative diagnosis and laparoscopic findings, patients had diagnosis of Chronic cholecystitis / biliary colic 68.25%, acute cholecystitis 23.75%, empyema gall bladder 7.25%, gallstone pancreatitis 0.5% and mucocele gallbladder 0.25%. Median operating time was 30min. Median hospital stay was 1 days (range 1 -20 days). Conversion rate was 1.25%. Postoperative complications included bleeding 0.5%, biliaryperitonitis due to cystic duct leak 0.25%, biloma 0.25%, sub hepaticabscess 0.25%, subcutaneous fat necrosis right flank at drain site 0.25%, umbilical trocarsite infection 2%, keloid at umbilical port site 0.25% and incisional hernia at umbilicus 0.25%. There was one hospital death due to myocardial infarction on 2nd post-operative day. Conclusion: Laparoscopic Cholecystectomy is associated with some serious complications

Deceased donor (DD) kidney quality is determined by calculating the Kidney Donor Profile Index (KDPI). Optimizing high KDPI (≥85%) DD transplant outcome is challenging. This retrospective study was performed to review our high KDPI DD transplant results to identify clinical practices that can improve future outcomes. We retrospectively calculated the KDPI for 895 DD kidney recipients transplanted between 1/2002 and 11/2013. Age, race, body mass index (BMI), retransplantation, gender, diabetes (DM), dialysis time, and preexisting coronary artery disease (CAD) (previous myocardial infarction (MI), coronary artery bypass (CABG), or stenting) were determined for all recipients. About 29.7% (266/895) of transplants were from donors with a KDPI ≥85%. By Cox regression older age, diabetes, female gender, and dialysis time >4 years correlated with shorter patient survival time. Diabetics with CAD who received a high KDPI donor kidney had a significantly increased risk of death (HR 4.33 (CI 1.82-10.30), P=.001) compared to low KDPI kidney recipients. The Kaplan-Meier survival curve for diabetic recipients of high KDPI kidneys was significantly worse if they had preexisting CAD (P<.001 by log-rank test). Patient survival using high KDPI donor kidneys may be improved by avoiding diabetic candidates with preexisting CAD. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

An unstable donor-recipient DNA complex in transformation of Bacillus subtilis

International Nuclear Information System (INIS)

Popowski, J.; Venema, G.

1978-01-01

In re-extracted DNA obtained shortly after uptake of transforming DNA by Bacillus subtilis, increased amounts of donor DNA radioactivity banding at the position of donor-recipient DNA complex (DRC) are observed in CsCl gradients, if the cells are irradiated with high doses of UV prior to reextraction of the DNA. Qualitatively, the same phenomenon is observed if lysates of transforming cells are irradiated. UV-irradiation of lysates of competent cells to which single-stranded DNA is added after lysis, does not result in linkage of this DNA to the chromosomal DNA. Two observations argue in favour of the formation of a specific labile complex between donor and resident DNA during transformation. Firstly, heterologous donor DNA from Escherichia coli, although being processed to single-stranded DNA in competent B. subtilis, does not seem to be linked to the recipient chromosome upon UV-irradiation, and secondly, the labile complex of donor and recipient DNA can be stabilized by means of treatment of the lysates of transforming cells with 4, 5 1 , 8-trimethylpsoralen in conjuction with long-wave-ultra violet light irradiation. This indicates that basepairing is involved in the formation of the complex. On the basis of these results we assume that the unstable complex of donor and recipient DNA is an early intermediate in genetic recombination during transformation. (orig.) [de

Mechanisms of immunological eradication of a syngeneic guinea pig tumor: participation of a component(s) of recipient origin in the expression of systemic adoptive immunity

Shu, S.; Fonseca, L.S.; Kato, H.; Zbar, B.

1983-01-01

The effects of carrageenan and trypan blue on the expression of adoptive immunity to the syngeneic guinea pig line 10 hepatoma were investigated. Adoptive immunity was assessed by observing dermal tumor growth in recipients of immune cells and by bioassays in which tumor challenge sites were transplanted into secondary hosts. Carrageenan abrogated transferred immunity in treated animals as evidenced by dermal tumor growth and by development of fatal ascites tumors in peritoneal cavities of the secondary hosts. Trypan blue, on the other hand, did not abrogate transferred immunity in treated animals. However, the i.p. bioassay revealed the presence of line 10 cells in the tumor challenge sites 10 days after adoptive transfer. In vitro and in vivo exposure of immune spleen cells to carrageenan or trypan blue had no significant effect on the subsequent adoptive transfer, indicating that the inhibitory activity of these agents cannot be attributed to direct toxicity to immune lymphoid cells. Tumor challenge sites taken from carrageenan or trypan blue-treated animals 5 days after adoptive transfer failed to grow progressively when transplanted s.c. into secondary hosts. This observation suggests the presence of immune cells at tumor challenge sites. Thus, the inhibitory effects were unlikely due to interference with recirculation of the i.v.-transferred immune cells. Adoptive immunity was not influenced in guinea pigs that received a lethal dose of irradiation (500 rads). These results demonstrate that a recipient component(s) sensitive to carrageenan and trypan blue but resistant to radiation is essential to the expression of adoptive immunity

Temporal stability of music perception and appraisal scores of adult cochlear implant recipients.

2010-01-01

An extensive body of literature indicates that cochlear implants (CIs) are effective in supporting speech perception of persons with severe to profound hearing losses who do not benefit to any great extent from conventional hearing aids. Adult CI recipients tend to show significant improvement in speech perception within 3 mo following implantation as a result of mere experience. Furthermore, CI recipients continue to show modest improvement as long as 5yr postimplantation. In contrast, data taken from single testing protocols of music perception and appraisal indicate that CIs are less than ideal in transmitting important structural features of music, such as pitch, melody, and timbre. However, there is presently little information documenting changes in music perception or appraisal over extended time as a result of mere experience. This study examined two basic questions: (1) Do adult CI recipients show significant improvement in perceptual acuity or appraisal of specific music listening tasks when tested in two consecutive years? (2) If there are tasks for which CI recipients show significant improvement with time, are there particular demographic variables that predict those CI recipients most likely to show improvement with extended CI use? A longitudinal cohort study. Implant recipients return annually for visits to the clinic. The study included 209 adult cochlear implant recipients with at least 9 mo implant experience before their first year measurement. Outcomes were measured on the patient's annual visit in two consecutive years. Paired t-tests were used to test for significant improvement from one year to the next. Those variables demonstrating significant improvement were subjected to regression analyses performed to detect the demographic variables useful in predicting said improvement. There were no significant differences in music perception outcomes as a function of type of device or processing strategy used. Only familiar melody recognition (FMR

Background and purpose: Orbital non-Hodgkin's lymphomas (NHL) have traditionally been treated with radiation. Forty-eight patients presenting with orbital NHL were treated with radiation and were evaluated for local control, overall survival, cause-specific survival, and complications. Materials and methods: Forty-five patients had low-grade and 3 patients had intermediate-grade histologic findings. Orbit-only disease occurred in 22 patients, the conjunctiva in 16, both in five, and lacrimal gland only in five. Patient age ranged from 35 to 94 years (median, 68). Ann Arbor stages were cIEA (34), cIIEA (six), cIIIEA (two), and cIVEA (six). Radiation doses ranged between 15 and 53.8 Gy (median, 27.5 Gy). Results: Follow-up ranged from 0.14 to 18.23 years (median, 5.35). Median overall survival and cause-specific survival were 6.5 and 15.5 years, respectively. Patients with clinical stage I or II disease had significantly better overall and cause-specific survival than patients with stage III or IV disease. Ten-year relapse-free survival in 41 patients with stage I or II disease was 66%. However, there was continued downward pressure on relapse-free survival out to 18 years. One local failure occurred. Twenty-five patients sustained acute complications. There were 17 minor and four major late complications. All major late complications occurred with doses more than 35 Gy. Conclusions: Excellent local control with radiation doses ranging from 15 to 30 Gy is achieved. Patients with stage I or II disease have better overall and cause-specific survival than patients with stage III or IV disease. Late relapse occurs in sites other than the treated orbit, even in patients with early-stage disease. Doses 35 Gy or higher result in significant late complications and are therefore not indicated for patients with low-grade tumors

Suppression of adoptive antituberculosis immunity by normal recipient animals

Adoptive immunity is poorly expressed in normal syngeneic mice. This phenomenon was studied by using experimental antituberculosis immunity as a model system representing pure cell-mediated immunity. Expression of adoptive immunity was facilitated by pretreating recipients with sublethal ionizing radiation (500 rads) or high doses (200 mg/kg) of cyclophosphamide or by using adult thymectomized, lethally irradiated, bone-marrow-reconstituted (TXB) mice. Adult thymectomy was less effective, and a low dose of cyclophosphamide (20 mg/kg) was completely ineffective. The beneficial effect of sublethal irradiation was reduced over time; it persisted for 4 weeks and was absent after 8 weeks. Attempts to restore the suppressed state of normal mice to sublethally irradiated mice by using normal spleen or thymus cells did not succeed. Even in rats, which express adoptive antituberculosis immunity without immunosuppressive treatment, the use of sublethally irradiated or TXB recipients potentiated adoptive immunity. It was concluded that suppression of adoptive immunization in normal recipient mice is mediated predominantly, if not exclusively, by T lymphocytes that are sensitive to a number of immunosuppressive agents. The suppressor cells are long-lived and can be regenerated from precursors that are resistant to 500 but not to 900 rads of ionizing radiation
