    Donor-site morbidity following harvest of the radial forearm free flap was compared with that following harvest of the ulnar forearm free flap. Twenty-eight radial forearm and 27 ulnar forearm flaps were harvested in 55 patients with head and neck defects. Pressure perception was measured with Semmes-Weinstein monofilaments. Cold perception was tested with chloroethyl. Donor-site healing was evaluated. Patients were interviewed about grip and pinch strength and donor-site appearance. In the radial forearm free flap group, pressure perception and cold perception were reduced in the donor hand, whereas in the ulnar group, no differences were observed between the donor and unoperated hands. In the radial forearm group, 15 percent of patients experienced reduced strength in the donor hand, whereas in the ulnar forearm group, none of the patients reported reduced strength in the donor hand. In the radial forearm group, 14 percent had partial or complete loss of the skin graft, whereas in the ulnar forearm group, 4 percent had partial loss of the skin graft. In the radial forearm group, 18 percent of patients were dissatisfied with the appearance of the donor site, and no complaints were reported in the ulnar forearm group. The authors' study shows less donor site-morbidity following harvest of the ulnar forearm free flap than following harvest of the radial forearm free flap. These results emphasize that the ulnar forearm free flap should be considered as an alternative for the radial forearm free flap for reconstruction of soft-tissue defects. Therapeutic, III.

    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

    A novel technique to reduce donor site morbidity after radial forearm free flap (RFFF) harvest, using a local full-thickness skin graft (FTSG), is described. Thirty consecutive patients undergoing RFFF for head and neck reconstruction were enrolled in a prospective study. Donor site defect closure was performed with spindle-shaped FTSGs excised from the wavelike skin incision made for the vascular pedicle. Both the removal site of the FTSG on the volar forearm and the covered RFFF donor site healed uneventfully in 29 cases, with no impairment of function related to the skin graft. No skin graft failure and no exposure, tenting, or adherence of the flexor tendons occurred. All patients expressed satisfaction with postoperative pain, the functional outcome, and cosmetic appearance. Primary donor site defect closure could be achieved in all cases with the use of a local FTSG. This graft can be gained at the access incision for the vascular pedicle, avoids expansion of the incision for a local flap technique, and does not prolong wound healing, and thus reduces both donor site and graft site morbidity of the RFFF. This technique leads to an inconspicuous aesthetic result with no apparent relevant functional deficits and avoids the need for a second donor site.

    Aims The primary aim of this study was to determine the morbidity of a tibial strut autograft and characterize the rate of bony union following its use. Patients and Methods We retrospectively assessed a series of 104 patients from a single centre who were treated with a tibial strut autograft of > 5 cm in length. A total of 30 had a segmental reconstruction with continuity of bone, 27 had a segmental reconstruction without continuity of bone, 29 had an arthrodesis and 18 had a nonunion. Donor-site morbidity was defined as any event that required a modification of the postoperative management. Union was assessed clinically and radiologically at a median of 36 months (IQR, 14 to 74). Results Donor-site morbidity occurred in four patients (4%; 95% confidence interval (CI) 1 to 10). One patient had a stress fracture of the tibia, which healed with a varus deformity, requiring an osteotomy. Two patients required evacuation of a haematoma and one developed anterior compartment syndrome which required fasciotomies. The cumulative probability of union was 90% (95% CI 80 to 96) at five years. The type of reconstruction (p = 0.018), continuity of bone (p = 0.006) and length of tibial graft (p = 0.037) were associated with the time to union. Conclusion The tibial strut autograft has a low risk of morbidity and provides adequate bone stock for treating various defects of long bones. Cite this article: Bone Joint J 2018;100-B:667-74.

    The transverse myocutaneous gracilis (TMG) flap is a widely used alternative to abdominal flaps in autologous breast reconstruction. However, secondary procedures for aesthetic refinement are frequently necessary. Herein, we present our experience with an optimized approach in TMG breast reconstruction to enhance aesthetic outcome and to reduce the need for secondary refinements. We retrospectively analyzed 37 immediate or delayed reconstructions with TMG flaps in 34 women, performed between 2009 and 2015. Four patients (5 flaps) constituted the conventional group (non-optimized approach). Thirty patients (32 flaps; modified group) underwent an optimized procedure consisting of modified flap harvesting and shaping techniques and methods utilized to reduce denting after rib resection and to diminish donor site morbidity. Statistically significant fewer secondary procedures (0.6 ± 0.9 versus 4.8 ± 2.2; P < .001) and fewer trips to the OR (0.4 ± 0.7 versus 2.3 ± 1.0 times; P = .001) for aesthetic refinement were needed in the modified group as compared to the conventional group. In the modified group, 4 patients (13.3%) required refinement of the reconstructed breast, 7 patients (23.3%) underwent mastopexy/mammoplasty or lipofilling of the contralateral breast, and 4 patients (13.3%) required refinement of the contralateral thigh. Total flap loss did not occur in any patient. Revision surgery was needed once. Compared to the conventional group, enhanced aesthetic results with consecutive reduction of secondary refinements could be achieved when using our modified flap harvesting and shaping techniques, as well as our methods for reducing contour deformities after rib resection and for overcoming donor site morbidities. © 2017 Wiley Periodicals, Inc.

    Full Text Available BACKGROUND. Split thickness skin graft harvesting causes a certain degree of scaring on the donor site. Donor site scar can cause aesthetic and functional sequelae on the patient's body. Our goal was to study the process of donor site selection, and then evaluate donor site scars and their impact on patients. PATIENTS AND METHODS. This retrospective study included 45 patients aged 5 to 61 years (in average 36, who have been treated with STSG in the 2004–2010 period. 57.8% of them were men. On a follow-up visit, we photographed healed skin defects and donor sites. We then determined and compared the surface areas of skin defect and the donor site using the Adobe® Illustrator® CS5 computer program. Donor site scars were assessed according to the Vancouver scar scale (VSS. We examined scar’s light touch sensitivity with monofilaments and skin colouring compared to adjacent healthy skin using colorimeter. Patients were also interviewed about their treatment course in a form of a standardized questionnaire. RESULTS. Our research has revealed that 20.0% of patients participated in the decision making process of choosing the donor site, while in 80.0% the donor site was chosen by the surgeon himself. 6.7% of patients were not satisfied with their donor site. Most of the patients (37/45 had donor sites on their thighs. In average, the donor site surface area was 94% bigger than the skin defect area. We found statistically significant differences in VSS values, light touch sensitivity and skin colouring between donor site scaring and adjacent healthy skin. CONCLUSIONS. Donor site scar can represent a lasting aesthetic and functional disability for patients. Our research has shown that most of the patients do not participate in the donor site selection process, but are satisfied with their donor site. In most cases, STGSs are harvested from the thigh, other anatomical regions, where scarring would be aesthetically less obtrusive, are underused

    The authors aimed to accurately assess the donor site morbidity from iliac crest bone grafts for secondary bone grafting in patients with cleft lip and palate alveolar defects. Fifty patients between 3 months and 10 years following alveolar bone grafting for cleft lip and palate were entered into the study. Two-thirds of patients had no significant concerns about the donor site. The remaining third had some concerns about the appearance of their hips and less than 10% of patients expressing strong agreement with statements about concerns with shape, appearance, and self-consciousness about the iliac crest donor site. Examination findings showed the average length of scar being 5.4 cm and a third of patients having some minor palpable boney irregularities of the iliac crest. The authors found that the alveolar crest donor site is well tolerated by patients long term but has a measurable morbidity long term.

    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.

    2016-01-01

    The harvesting of a tooth as a candidate for tooth autotransplantation requires that the delicate dental tissues around the tooth be minimally traumatized. This is especially so for the periradicular tissues of the tooth root and the follicular tissues surrounding the crown. The aim of this report is to describe the use of piezosurgery as an attempt at morbidity reduction in the harvesting of teeth for autotransplantation. A piezosurgical handpiece and its selection of tips were easily adapted to allow the harvesting and delivery of teeth for autotransplantation purposes. Twenty premolar teeth were harvested using a piezosurgical device. The harvested teeth were subsequently successfully autotransplanted. All twenty teeth healed in a satisfactory manner without excessive mobility or ankyloses. Piezosurgery avoids some of the traumatic aspects of harvesting teeth and removing bone which are associated with thermal damage from the use of conventional rotary instruments or saws. Piezosurgery can be adapted to facilitate the predictable harvesting of teeth for autotransplantation purposes.

    Single-center studies have failed to link modest increases in total donor ischemic time to mortality after pediatric orthotopic heart transplant. We aimed to investigate whether prolonged total donor ischemic time is linked to pediatric intensive care morbidity after orthotopic heart transplant. Retrospective cohort review. Tertiary pediatric transplant center in the United Kingdom. Ninety-three pediatric orthotopic heart transplants between 2002 and 2006. Total donor ischemic time was investigated for association with early post-orthotopic heart transplant hemodynamics and intensive care unit morbidities. Of 43 males and 50 females with median age 7.2 (interquartile range 2.2, 13.0) yrs, 62 (68%) had dilated cardiomyopathy, 20 (22%) had congenital heart disease, and nine (10%) had restrictive cardiomyopathy. The mean total donor ischemic time was 225.9 (sd 65.6) mins. In the first 24 hrs after orthotopic heart transplant, age-adjusted mean arterial blood pressure increased (p total donor ischemic time was significantly associated with lower mean arterial blood pressure (p care unit (p = .004), and longer post-orthotopic heart transplant stay in hospital (p = .02). Total donor ischemic time was not related to levels of mean pulmonary arterial pressure (p = .62), left atrial pressure (p = .38), or central venous pressure (p = .76) early after orthotopic heart transplant. Prolonged total donor ischemic time has an adverse effect on the donor organ, contributing to lower mean arterial blood pressure, as well as more prolonged ventilation and intensive care unit and hospital stays post-orthotopic heart transplant, reflecting increased morbidity.

    Although new therapeutic approaches for burn treatment have made progress, there is still need for better methods to enhance wound healing and recovery especially in severely burned patients. Nanofibrillar cellulose (NFC) has gained attention due to its renewable nature, good biocompatibility and excellent physical properties that are of importance for a range of applications in pharmaceutical and biomedical fields. In the present study, we investigated the potential of a wood based NFC wound dressing in a clinical trial on burn patients. Previously, we have investigated NFC as a topical functionalized wound dressing that contributes to improve wound healing in mice. Wood based NFC wound dressing was tested in split-thickness skin graft donor site treatment for nine burn patients in clinical trials at Helsinki Burn Centre. NFC dressing was applied to split thickness skin graft donor sites. The dressing gradually dehydrated and attached to donor site during the first days. During the clinical trials, physical and mechanical properties of NFC wound dressing were optimized by changing its composition. From patient 5 forward, NFC dressing was compared to commercial lactocapromer dressing, Suprathel® (PMI Polymedics, Germany). Epithelialization of the NFC dressing-covered donor site was faster in comparison to Suprathel®. Healthy epithelialized skin was revealed under the detached NFC dressing. NFC dressing self-detached after 11-21days for patients 1-9, while Suprathel® self-detached after 16-28days for patients 5-9. In comparison studies with patients 5-9, NFC dressing self-detached on average 4days earlier compared with Suprathel®. Lower NFC content in the material was evaluated to influence the enhanced pliability of the dressing and attachment to the wound bed. No allergic reaction or inflammatory response to NFC was observed. NFC dressing did not cause more pain for patients than the traditional methods to treat the skin graft donor sites. Based on the

    Traditional donor-site closure has been associated with serious esthetic and functional morbidity. The purpose of this study was to assess morbidity in esthetics and function and measure the postoperative complications of the radial forearm free flap (RFFF) donor site after using combined local triangular full-thickness skin grafting. This prospective study of patients who underwent reconstruction of head and neck defects using an RFFF was conducted from July 2008 through December 2014. The donor site was repaired with a combined local triangular full-thickness skin graft. Quality of the scar, color match, tendon exposure, presence of necrosis, dehiscence of the suture, and presence of dysesthesia were recorded and analyzed using SPSS 21.0 software. One hundred consecutive patients (71 male and 29 female) underwent RFFF harvesting. RFFF donor-site defects ranged from 15 to 70 cm2; partial skin graft loss occurred in 7% of patients. Five patients (5%) had small dehiscences of the forearm skin graft, and 2 cases (2%) presented tendon exposure. In all cases, these sites healed secondarily by conservative management, with no final impairment of function. Esthetic results were considered excellent in 87%, good in 11%, and suboptimal in 2% of the cases. The combined local triangular full-thickness skin graft is a reliable method for closing RFFF donor-site defects because it obviates a second surgical site, it provides excellent color match and pliability, and it can be used for covering large defects of the donor site.

    The management of split-thickness skin graft donor sites is targeted towards promoting the healing process, reducing pain. This has been an inconclusive topic. The aim of this study was to list and to discuss the French practices in term of split-thickness skin graft (STSG) donor site dressing. Multicentric national study by questionnaire (Google Drive(®)) for the attention of the plastic and/or pediatric surgeons. The type of dressing used on skin and sclap and the rhythm of dressing changes were analyzed. The study included 26 surgical centers on 40 contacted. The alginate is mainly used (Algostéril(®)) (17/26). It is left in position until healing (13/17). Five other types of dressings have been reported: paraffin gauze (3/26), lipidocolloides (1/26), Mepitel(®) (1/26), Mepilex(®) (1/26), indifferent use of gauze or alginate dressings (4/26). Twenty-two out of 26 centers make no difference in dressing choice between skin and scalp. Medical practices did not differ between adult or pediatric departments. Cost-effectiveness has become an important issue in wound management, requiring judicious use. The lack of consensus regarding split-thickness skin graft donor site dressing and our clinical practices force us to reconsider the best therapeutic option. This study coupled with the analysis of the literature highlights the difficulties of the practitioner in choosing the best dressing. The alginate seems to get the preference of our practices by its ease of use, its absence of change (reduces pain by limiting manipulations) and its moderate cost.

    The authors want to evaluate the efficacy of fibrillary tabotamp dressing in skin graft-donor site. A comparison was made with Vaseline gauzes. Tabotamp is an absorbable haemostatic product of Ethicon (Johnson and Johnson) obtained by sterile and oxidized regenerated cellulose (Rayon). It is used for mild to moderate bleeding. 276 patients were subject to skin graft and divided into two group: Group A and Group B. The donor site of patients in Group A was medicated with fibrillary tabotamp, while the patients of Group B were medicated only with Vaseline gauze. We recorded infection, timing of healing, number of dressing change, the pain felt during and after the dressing change with visual analog scale (VAS) and a questionnaire. Patients allocated in Group A healed faster than the Group B. Questionnaires and VAS analysis showed lower pain felt, lower intake of pain drugs and lower infection rate in the Group A than the Group B. Analysis of coast showed lower dressing change in Group A than the Group B. We believe that the use of tabotamp is a very viable alternative to improve healing.

    Full Text Available Background The free anterolateral thigh (ALT flap has been widely used for various kinds of reconstructions. However, delayed healing at the donor site occasionally occurs due to wound dehiscence or the partial loss of grafted skin at the donor site. The aim of the present study was to identify reliable predictive factors for delayed healing at the donor site after the harvest of a free ALT flap. Methods This study included 52 patients who underwent reconstructive procedures using free ALT flaps. The delayed healing group included patients with wounds at the donor site that had not healed over 3 weeks after surgery, and the normal healing group included patients who showed wound healing within 3 weeks after surgery. Multivariate logistic regression models were created to identify the risk factors for delayed healing at the ALT flap donor site. Results Among the 52 patients, 24 (46.2% showed delayed healing at the donor site, and 6 patients required additional operative treatment. A high preoperative body mass index (BMI, smoking, and skin grafting were found to be significantly associated with delayed healing at the ALT donor site. Of the 37 patients who underwent skin grafting, 23 (62% experienced delayed healing at the donor site. Conclusions A high preoperative BMI, smoking, and skin grafting were risk factors for delayed healing at the free ALT donor site. Skin grafting at the ALT donor site should be avoided in patients with a high BMI or a habit of smoking.

    Osteochondral Autologous Transplant (OATs) as a treatment option for Osteochondral lesions (OCLs) of the talar dome frequently uses the distal femur as the donor site which is associated with donor site morbidity in up to 50%. Some studies have described the presence of hyaline cartilage in the posterior superior calcaneal tuberosity. The aim of this study was to evaluate the posterior superior calcaneal tuberosity to determine if it can be a suitable donor site for OATs of the talus In this cadaveric study, we histologically evaluated 12 osteochondral plugs taken from the posterior superior calcaneal tuberosity and compared them to 12 osteochondral plugs taken from the talar dome. In the talar dome group, all samples had evidence of hyaline cartilage with varying degrees of GAG staining. The average hyaline cartilage thickness in the samples was 1.33 mm. There was no evidence of fibrocartilage, fibrous tissue or fatty tissue in this group. In contrast, the Calcaneal tuberosity samples had no evidence of hyaline cartilage. Fibrocartilage was noted in 3 samples only. We believe that the structural differences between the talus and calcanium grafts render the posterior superior clancaneal tuberosity an unsuitable donor site for OATs in the treatment of OCL of the talus.

    Anterior cruciate ligament (ACL) tears are highly incident injuries in young athletes within our work area. The use of the patellar graft, despite being the treatment of choice, presents post-operative problems such as anterior knee pain, which limits its use and leads to preference being taken for alternative grafts. Our aim was to evaluate if the application of PRGF reduces anterior knee pain in donor site in BTB-ACL reconstruction. 43 patients were included in the double-blinded and randomized clinical trial comparing two patient groups who underwent ACL reconstruction using patellar tendon graft, comparing anterior knee pain with and without the application of PRGF at the donor site after harvesting the graft. The PRGF group showed decreased donor site pain in comparison to the control group, with significant differences in the first two months of follow-up. The application of PRGF decreased donor site pain compared to the control group.

    A retrospective analysis of halo device associated morbidity over a 4-year period. To assess the impact of a new pin care regimen on halo pin site related morbidity. Halo orthosis treatment still has a role in cervical spine pathology, despite increasing possibilities of open surgical treatment. Published figures for pin site infection range from 12% to 22% with pin loosening from 7% to 50%. We assessed the outcome of a new pin care regimen on morbidity associated with halo spinal orthoses, using a retrospective cohort study from 2001 to 2004. In the last two years, our pin care regimen was changed. This involved pin site care using chlorhexidene & regular torque checking as part of a standard protocol. Previously, povidone iodine was used as skin preparation in theatre, followed by regular sterile saline cleansing when pin sites became encrusted with blood. There were 37 patients in the series, the median age was 49 (range, 22-83) and 20 patients were male. The overall infection rate prior to the new pin care protocol was 30% (n=6) and after the introduction, it dropped to 5.9% (n=1). This difference was statistically significant (p<0.05). Pin loosening occurred in one patient in the group prior to the formal pin care protocol (3%) and none thereafter. Reduced morbidity from halo use can be achieved with a modified pin cleansing and tightening regimen.

    The treatment of wound healing disturbances of the radial forearm free flap donor site after reconstructive surgery is typically long and burdensome and often requires additional surgery. Cold atmospheric plasma is a promising approach to overcome these impairments. The aim of this proof of concept study was to evaluate the clinical outcome of plasma irradiation in patients with wound healing disorders with exposed brachial tendons of the radial forearm. Four patients (mean age 64.2 years, range 44 to 80) who had undergone radial forearm free flap procedures and developed wound healing disturbance leading to exposed flexor tendons were included in the present prospective case series. In addition to routine wound care, all sites were irradiated with cold atmospheric plasma. The primary outcome variable was complete wound closure. In all patients, complete wound repair in terms of the absence of tendon exposure was observed within a mean treatment time of 10.1 weeks (range 4.9 to 16). No undesirable side effects were observed, and no inflammation or infection occurred. Cold atmospheric plasma could offer a reliable conservative treatment option for complicated wound healing disturbances. This was exemplarily shown in the case of radial forearm free flap donor site morbidity with exposed flexor tendons in the present study.

    Although single-port donor nephrectomy offers improved cosmetic outcomes, technical challenges have limited its application to selected centers. Our center has performed over 400 single-port donor nephrectomies. The da Vinci single-site robotic platform was utilized in an effort to overcome the steric, visualization, ergonomic, and other technical limitations associated with the single-port approach. Food and Drug Administration device exemption was obtained. Selection criteria for kidney donation included body mass index da Vinci single-site platform. Our experience supported the safety of this approach but found that the technology added cost and complexity without tangible benefit. Development of articulating instruments, energy, and stapling devices will be necessary for increased application of robotic single-site surgery for donor nephrectomy. Copyright © 2017 Elsevier Inc.

    A prospective controlled trial was carried out to assess the healing efficacy of calcium alginate and paraffin gauze on split skin graft donor sites. Thirty patients were randomised to the calcium alginate group and 21 to the paraffin gauze group. The donor sites were assessed at 10 days post harvesting to determine if they were completely healed (100%) or not. Twenty one of the 30 patients dressed with calcium alginate were completely healed at day 10, while only 7\\/21 in the paraffin gauze group were healed (p < 0.05). There were two infections in the study, both occurring in the alginate group while there was no difference in dressing slippage between the two groups. Calcium alginate dressings provide a significant improvement in healing split skin graft donor sites.

    Delayed or even lack of healing of a split-thickness skin graft (STSG) donor site is a potential problem with elderly patients or those with poor wound healing capabilities. A proactive solution that may minimize this risk is to regraft that donor site using otherwise discarded skin graft remnants. A prospective, nonrandomized, consecutive study was designed to compare the time to healing of the commonly used anterior thigh STSG donor site in patients who had routine dressings (n = 113) versus those with comorbidities known to adversely affect wound healing and had planned regrafting (n = 204). Those comorbidities included age (≥65 years), diabetes mellitus, peripheral vascular disease, chronic renal disease, and chronic steroid use. The average number of comorbidities in the regrafted subgroup versus those not regrafted was 1.41 and 0.31, respectively. This was considered to be a significant difference ( P skin graft materials when so indicated and can be a proactive solution to a potentially cumbersome dilemma.

    The management of the donor site after harvesting a skin graft is an important issue, as patients often report more discomfort at the donor site than at the recipient site. There is, however, a plethora of dressings available for the treatment and management of donor sites, yet, there is no widely accepted method established for these partial thickness wounds. Honey has been found to be useful in the treatment of burns and other wounds, split-thickness skin graft donor sites are like partial thickness burn wounds and honey's healing effect on burn wound can also be expected on these types of wounds. Therefore, this study was undertaken to evaluate the effect of honey on skin graft donor sites. From 2002 to 2004, 100 patients who have undergone skin grafting for various reasons formed the material of the randomized study divided into two groups of 50 each in honey-treated group and Vaseline gauze-treated group. Graft donor site area ranged from 30 to 48 cm(2), mean 32.6 cm(2). In the group treated with honey, 90 % of the patients had nil or only moderate pain, whereas in the group treated with Vaseline gauze,88 % had nil or mild pain (p > 0.001, not significant). There were no allergic reactions in any of the patients in either group. On opening of the dressing on the 7th day, epithelialization has occurred in 48 patients as compared to 39 in group 2, i.e., donor sites treated with Vaseline gauze (p < 0.05, statistically significant). By the 10th day, all the wounds healed in honey-treated group, whereas 76 % of wounds healed in Vaseline gauze-treated group (p < 0.05). At 1 month follow-up, the results were comparable in both groups, with regard to patient satisfaction. In conclusion, honey-impregnated gauze causes less pain and heals donor sites wounds faster with good cosmetic result.

    Although the recipient site in burn wounds is dressed with universally accepted materials, the ideal management of split-thickness skin donor sites remains controversial. The aim of our study is to compare two methods of wound dressing in donor sites of split-thickness skin graft in patients undergoing burn wound reconstructive surgery. Forty-two consecutive patients with second- and third-degree burns with a total body surface area between 20 and 40 % were enrolled in this randomized clinical trial conducted in Motahari Burn Hospital in Tehran, Iran. In each patient, two anatomic areas with similar features were randomly selected as intervention and control donor sites. The intervention site was dressed with amniotic membrane, whereas the control site was treated with Vaseline-impregnated gauze. Wounds were examined daily by expert surgeons to measure the clinical outcomes including duration of healing, severity of pain, and infection rate. The mean ± SD age of patients was 31.17 ± 13.72 years; furthermore, burn percentage had a mean ± SD of 31.19 ± 10.56. The mean ± SD of patients' cooperation score was 1.6 ± 0.79 in the intervention group compared with 2.93 ± 0.71 in the control group, revealing a statistically significant difference (P  0.05). Amniotic membrane as an alternative for dressing of skin graft donor sites provides significant benefits by increasing patients' comfort via diminishing the number of dressing changes and facilitating the process of wound healing.

    Squamous cell carcinomas are malignant tumours of epithelial origin that can appear on sites subjected to chronic inflammation after a period of several years. The rapid development of squamous cell carcinoma at the donor site for a thin skin graft is a rare and poorly understood situation. We report the case of a patient undergoing thin skin grafting to cover the area of removal of a vertex squamous cell carcinoma and in whom squamous cell carcinoma appeared at the donor site within 9 weeks. In our case, we ruled out intraoperative contamination because two sets of surgical instruments were used. Given the number of cases reported in the literature, a chance event seems unlikely. The hypothesis of an acute inflammatory process caused by scarring of the thin skin graft site appears to us the most convincing. Development of cancer at the graft donor site may thus be added to the list of complications of thin skin grafting. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Full Text Available Abstract Background Donor site wounds after split-skin grafting are rather 'standard' wounds. At present, lots of dressings and topical agents for donor site wounds are commercially available. This causes large variation in the local care of these wounds, while the optimum 'standard' dressing for local wound care is unclear. This protocol describes a trial in which we investigate the effectiveness of various treatment options for these donor site wounds. Methods A 14-center, six-armed randomized clinical trial is being carried out in the Netherlands. An a-priori power analysis and an anticipated dropout rate of 15% indicates that 50 patients per group are necessary, totaling 300 patients, to be able to detect a 25% quicker mean time to complete wound healing. Randomization has been computerized to ensure allocation concealment. Adult patients who need a split-skin grafting operation for any reason, leaving a donor site wound of at least 10 cm2 are included and receive one of the following dressings: hydrocolloid, alginate, film, hydrofiber, silicone dressing, or paraffin gauze. No combinations of products from other intervention groups in this trial are allowed. Optimum application and changes of these dressings are pursued according to the protocol as supplied by the dressing manufacturers. Primary outcomes are days to complete wound healing and pain (using a Visual Analogue Scale. Secondary outcomes are adverse effects, scarring, patient satisfaction, and costs. Outcome assessors unaware of the treatment allocation will assess whether or not an outcome has occurred. Results will be analyzed according to the intention to treat principle. The first patient was randomized October 1, 2009. Discussion This study will provide comprehensive data on the effectiveness of different treatment options for donor site wounds. The dressing(s that will prevail in effectiveness, satisfaction and costs will be promoted among clinicians dealing with such

    BACKGROUND Graft-site candidiasis rarely develops in solid organ transplant recipients; however, severe life-threatening complications can occur. We report the course of 3 solid organ transplant recipients developing graft-site candidiasis. CASE REPORT All grafts, consisting of 2 kidneys and 1 liver, were procured from a single donor. Patient data were collected from our database. Candida albicans was isolated from a swab taken during multiple-organ recovery. Complications associated with candidiasis occurred in all 3 recipients with preservation of the liver transplant. Both renal transplant recipients had vascular complications, eventually resulting in graft nephrectomy and subsequent return to dialysis. The patients recovered completely without residual effects of their prior fungal infection. CONCLUSIONS Fungal infections in solid organ transplant recipients are rare. Since the sequelae of these infections are serious and usually pertain to more than 1 recipient at a time, antifungal prophylaxis may be warranted in select donors.

    Defects of the glabrous skin surfaces of the palm and fingers result from numerous causes including larger fingertip injuries, unhealed burns, and after surgery for diverse pathologies. The qualities of glabrous skin are specifically tailored to the functional requirements of high-shear strength and robustness. Despite these unique properties, graft reconstruction of defects in the glabrous regions of the hand is frequently achieved with skin from nonglabrous donor sites such as the medial forearm. Nonglabrous skin has a poor color and texture match for such applications and is frequently associated with tender and unsightly donor scars. We describe our experiences of harvesting full-thickness grafts from the glabrous skin centered over the proximal flexion crease at the level of the metacarpophalangeal joint of the thumb. We have utilized this site to harvest skin grafts of up to 2 cm in width for the resurfacing of small-sized to medium-sized defects on the palmar surfaces of the hands and fingers in 28 patients under both traumatic and elective circumstances. The skin has an excellent type-match to the defect and is quick and easy to harvest due to its adjacent location to the defect. The donor scar matures quickly, and as it lies along the thumb base crease, it runs along one of the least used contact surfaces, thereby limiting the potential discomfort associated with FTSG harvest sites from other areas. Patient satisfaction with the procedure has been high, and it represents a useful alternative to traditional nonglabrous skin graft donor sites for small-sized to medium-sized defects.

    Radial forearm free flap is the most reliable flap for intraoral soft tissue reconstruction after cancer ablation surgery. However, unesthetic scar of the donor site and the need for a second donor site for skin graft are major disadvantages of the forearm flap. The purpose of this study was to report the clinical results of double-layered collagen graft to the donor site of the forearm free flap without skin graft. Twenty-two consecutive patients who underwent oral cancer ablation and forearm reconstruction between April 2010 and November 2013 were included in this study. Male to female ratio was 12:10, and average age was 61.0 years old (27-84). Double-layered collagen was grafted to the donor site of the forearm free flap and healed for secondary intention. Upper silicone had been trimmed at the periphery during secondary intention, and dry dressing was used. Postoperative scar healing and esthetic results and function were evaluated. An average follow-up period was 34.9 months. The scar area was decreased to 63.9 % in average. The complete healing was obtained between 1.5 and 3 months according to the defect size. There was no functional defect or impairment 3 months after operation. All patients were satisfied with the esthetic results. Three patients died of recurred cancer. Double-layered collagen graft was successfully performed in this study. Without the thigh skin graft, patients had experienced less painful postoperative healing periods and discomfort.

    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.

    Split skin graft (SSG) is one of the most commonly performed operations on any Plastic Surgery service. Rate of donor site healing is affected by various factors including the type of dressing applied. The aim of this study was to survey the practice of plastic surgeons in the sub region with respect to management of SSG donor site and see how it conforms to international standards. Structured questionnaires on various aspects of the harvest and management of SSG donor sites were administered to plastic surgeons during the 53rd annual conference of the West African College of Surgeons (WACS) at Lome, Togo in March 2013. The data were analyzed using descriptive statistics. There were 47 respondents out of 55 plastic surgeons from four West African countries, which represented 85.4% of registered participants at the plastic surgery section of the conference. All the respondents performed SSG regularly, and the thigh was the most commonly used donor site. Different types of paraffin gauze remained the most commonly used primary donor site dressing. Only 17% of the respondents apply a topical local anaesthetic agent on the donor site. The choice of SSG donor site dressing in the sub region was driven mainly by availability. Concerted efforts must be made to access newer wound care products for optimum management of this commonly performed operation.

    Full Text Available Introduction. Surgery-induced oxidative stress increases the risk of perioperative complications and delay in postoperative recovery. In mice, short-term preoperative dietary and protein restriction protect against oxidative stress. We investigated the feasibility of a calorie- and protein-restricted diet in two patient populations. Methods. In this pilot study, 30 live kidney donors and 38 morbidly obese patients awaiting surgery were randomized into three groups: a restricted diet group, who received a synthetic liquid diet with 30% fewer calories and 80% less protein for five consecutive days; a group who received a synthetic diet containing the daily energy requirements (DER; and a control group. Feasibility was assessed using self-reported discomfort, body weight changes, and metabolic parameters in blood samples. Results. Twenty patients (71% complied with the restricted and 13 (65% with the DER-diet. In total, 68% of the patients reported minor discomfort that resolved after normal eating resumed. The mean weight loss on the restricted diet was significantly greater (2.4 kg than in the control group (0 kg, p = 0.002, but not in the DER-diet (1.5 kg. The restricted diet significantly reduced levels of serum urea and plasma prealbumin (PAB and retinol binding protein (RBP. Conclusions. A short-term preoperative calorie- and protein-restricted diet is feasible in kidney donors and morbidly obese patients. Compliance is high and can be objectively measured via changes in urea, PAB, and RBP levels. These results demonstrate that this diet can be used to study the effects of dietary restriction on surgery-induced oxidative stress in a clinical setting.

    Full Text Available Abstract Background The area of Gela was included among the 57 Italian polluted sites of national interest for environmental remediation because of its widespread contamination from a petrochemical complex. The present study investigates mortality and morbidity of the cohort of Gela petrochemical workers with the aim of disentangling occupational from residential risk. Methods Mortality was assessed for 5,627 men hired from 1960, year of the plant start-up, to 1993; it was followed up for vital status in the period 1960–2002. Morbidity was analysed for 5,431 workers neither dead nor lost to follow-up from 1960 to 2001 and was based on Hospital Discharge Records in the period 2001–2006. The work experience was classified in terms of job categories such as blue collars, white collars, and both – workers who shifted from blue to white collar (95% or vice versa. An ad hoc mobility model was applied to define qualitative categories of residence in Gela, as residents and commuters. Standardized Mortality Ratios (SMRs and Mortality Rate Ratios (MRRs were computed, the latter by using a Poisson regression model. Morbidity was analyzed in terms of Hospital Discharge Odds Ratios (HDORs through a logistic regression model. While performing the internal comparisons, white collars was the reference category for the job analysis, and commuters was the reference category for the residential analysis. Results In the light of epidemiological evidence about health risk from petrochemical industries in both occupational and environmental settings, and/or on the basis of information about occupational and residential contamination and health risk in the area of Gela, noteworthy results are shown for lung cancer [MRR: 2.11 (CI 90%; 0.96-4.63 in blue collars; 1.71 (1.09-2.69 in residents], respiratory diseases [HDOR: 2.0 (1.0-3.0 in blue collars; 1.4 (0.96-2.06 in residents] and genitourinary diseases [HDOR: 1.34 (1.06-1.68 in blue collars; 1.23 (1.04-1.45 in

    Objective Morbidity associated with surgical site infection (SSI) following nonshunt pediatric neurosurgical procedures is poorly understood. The purpose of this study was to analyze acute morbidity and mortality associated with SSI after nonshunt pediatric neurosurgery using a nationwide cohort. Methods The authors reviewed data from the American College of Surgeons National Surgical Quality Improvement Program Pediatric (NSQIP-P) 2012–2014 database, including all neurosurgical procedures performed on pediatric patients. Procedures were categorized by Current Procedural Terminology (CPT) codes. CSF shunts were excluded. Deep and superficial SSIs occurring within 30 days of an index procedure were identified. Deep SSIs included deep wound infections, intracranial abscesses, meningitis, osteomyelitis, and ventriculitis. The following outcomes occurring within 30 days of an index procedure were analyzed, along with postoperative time to complication development: sepsis, wound disruption, length of postoperative stay, readmission, reoperation, and death. Results A total of 251 procedures associated with a 30-day SSI were identified (2.7% of 9296 procedures). Superficial SSIs were more common than deep SSIs (57.4% versus 42.6%). Deep SSIs occurred more frequently after epilepsy or intracranial tumor procedures. Superficial SSIs occurred more frequently after skin lesion, spine, Chiari decompression, craniofacial, and myelomeningocele closure procedures. The mean (± SD) postoperative length of stay for patients with any SSI was 9.6 ± 14.8 days (median 4 days). Post-SSI outcomes significantly associated with previous SSI included wound disruption (12.4%), sepsis (15.5%), readmission (36.7%), and reoperation (43.4%) (p neurosurgery. Rates of SSI-associated complications are significantly lower in patients with superficial infection than in those with deep infection. There were no cases of SSI-related mortality within 30 days of the index procedure. PMID:28186474

    Bone graft surgery is often necessary for reconstruction of craniofacial defects after trauma, tumor, infection or congenital malformation. In this operative technique the removed or missing bone segment is filled with a bone graft. The mainstay of the craniofacial reconstruction rests with the replacement of the defected bone by autogeneous bone grafts. To achieve sufficient incorporation of the autograft into the host bone, precise planning and simulation of the surgical intervention is required. The major problem is to determine as accurately as possible the donor site where the graft should be dissected from and to define the shape of the desired transplant. A computer-aided method for semi-automatic selection of optimal donor sites for autografts in craniofacial reconstructive surgery has been developed. The non-automatic step of graft design and constraint setting is followed by a fully automatic procedure to find the best fitting position. In extension to preceding work, a new optimization approach based on the Levenberg-Marquardt method has been implemented and embedded into our computer-based surgical planning system. This new technique enables, once the pre-processing step has been performed, selection of the optimal donor site in time less than one minute. The method has been applied during surgery planning step in more than 20 cases. The postoperative observations have shown that functional results, such as speech and chewing ability as well as restoration of bony continuity were clearly better compared to conventionally planned operations. Moreover, in most cases the duration of the surgical interventions has been distinctly reduced.

    The black-white maternal mortality disparity is the largest disparity among all conventional population perinatal health measures, and the mortality gap between black and white women in New York City has nearly doubled in recent years. For every maternal death, 100 women experience severe maternal morbidity, a life-threatening diagnosis, or undergo a life-saving procedure during their delivery hospitalization. Like maternal mortality, severe maternal morbidity is more common among black than white women. A significant portion of maternal morbidity and mortality is preventable, making quality of care in hospitals a critical lever for improving outcomes. Hospital variation in risk-adjusted severe maternal morbidity rates exists. The extent to which variation in hospital performance on severe maternal morbidity rates contributes to black-white disparities in New York City hospitals has not been studied. We examined the extent to which black-white differences in severe maternal morbidity rates in New York City hospitals can be explained by differences in the hospitals in which black and white women deliver. We conducted a population-based study using linked 2011-2013 New York City discharge and birth certificate datasets (n = 353,773 deliveries) to examine black-white differences in severe maternal morbidity rates in New York City hospitals. A mixed-effects logistic regression with a random hospital-specific intercept was used to generate risk-standardized severe maternal morbidity rates for each hospital (n = 40). We then assessed differences in the distributions of black and white deliveries among these hospitals. Severe maternal morbidity occurred in 8882 deliveries (2.5%) and was higher among black than white women (4.2% vs 1.5%, P rates among New York City hospitals ranged from 0.8 to 5.7 per 100 deliveries. White deliveries were more likely to be delivered in low-morbidity hospitals: 65% of white vs 23% of black deliveries occurred in hospitals in the lowest

    The purpose of this study is to compare the success rates of fat-graft myringoplasties harvesting adipose grafts from different donor sites (ear lobule vs abdomen). The clinical records of 61 patients (24 males and 37 females) who underwent fat-plug myringoplasty (FPM) were reviewed retrospectively. Fat from ear lobule (FEL) and abdominal fat were used as graft materials. The impact of age, gender, systemic diseases, topography of the perforation, utilization of fat graft materials of different origin on the tympanic membrane closure rate and the effect of FPM on hearing gain was analyzed. Our tympanic membrane (TM) closure rate was 82 %. No statistical significant difference was observed regarding age, gender, comorbidities (septal deviation, hypertension and diabetes mellitus) or habits (smoking). Posterior TM perforations had significantly lower healing rate. The change in TM closure rate considering different adipose tissue donor sites was not statistically significant. The hearing gain of the patients was mostly below 20 dB. Fat-plug myringoplasty (FPM) is a safe, cost-effective and easy operation for selected patients. Abdominal fat graft is as effective as ear lobe fat graft on tympanic membrane healing, has cosmetic advantages and should be taken into consideration when planning fat as the graft source.

    Objective: To compare the effectiveness of bupivacaine moistened dressing and conventional dressing in patients requiring split thickness skin graft for reconstruction of various defects. Study Design: Randomized controlled trial. Place and Duration of Study: Department of Plastic Surgery and Burns Unit, Mayo Hospital, King Edward Medical University, Lahore, from January 2011 to January 2013. Methodology: One hundred and fifty patients requiring split thickness skin grafting for various soft tissue defects were divided into two groups A and B, with 75 patients in each group. In Group A, skin graft donor site dressing was kept moist with 12 mL/100 cm/sub 2/ of 0.25% bupivacaine solution and in Group B, dressing was moistened with same amount of normal saline. Outcome was measured by calculating rescue analgesia requirements in the two groups after 24 hours. Significance was determined by comparing analgesia sparing effect of each dressing using chi-square test. Results: In Group A, 5 out of 75 (6.7%) patients required rescue analgesia. In Group B, 72 out of 75 (96%) patients required rescue analgesia (p < 0.0001). There was 93.3% effectiveness of bupivacaine soaked dressing while only 4% effectiveness of conventional dressing. Conclusion: Bupivacaine soaked dressing is much more effective in pain relief and in reducing the requirement of rescue analgesia, in early postoperative period, at split thickness skin graft donor site compared to the conventional dressing.

    Dipyridyl sulphide ligands 4-(pyridin-4-ylmethylthio)pyridine (abbreviated as L1) and 3-(pyridin-4-ylmethylthio)pyridine (abbreviated as L2) have been designed and used as μ-{sub N},{sub N}-bridging linkages to construct coordination polymers with free –S–CH{sub 2}– groups as secondary donor sites. By use solvent control method, coordination polymers ([Ag{sub 3}SO{sub 4}(L1){sub 3}](Cl)·4.5H{sub 2}O){sub ∞}(1), ([Ag{sub 2}SO{sub 4}(L1){sub 2}]·6H{sub 2}O·2CH{sub 3}OH){sub ∞}(2), ([Ag{sub 2}SO{sub 4}(L2){sub 2}]·H{sub 2}O){sub ∞}(3) and ([Ag{sub 4}(SO{sub 4}){sub 2}(L2){sub 4}]·5H{sub 2}O){sub ∞}(4) with different architectures were obtained. Complexes 1, 3 and 4 feature 1D channel with different sizes and structures. Complex 1 exhibits guest exchange by THF and 1,4-dioxane, and Hg{sup 2+} sorption ability from solution due to its relative larger channel and available bonding sites of –S– exposed to the channel region. All complexes have been characterized through single-crystal and powder X-ray diffraction (PXRD), FT-IR spectra, X-ray photoelectron spectroscopy (XPS), elemental and thermogravimetric analyses. The guest exchange and Hg{sup 2+} sorption were monitored and identified, and the structure-property relationship of coordination polymers 1–4 are discussed. - Graphical abstract: Coordination polymers of silver(I) sulfate with secondary donor sites are shown guest exchange property and Hg{sup 2+} absorb ability from solution. This work provides a new method to construct functional materials with potential application. - Highlights: • New example of constructing functional coordination polymer with secondary donor methylthio group. • Guest exchange and interesting Hg(II) absorb ability from solution are investigated. • New method to construct functional materials with potential application.

    Full Text Available Clinical waste is ineffectively treated and disposed in Cameroon. Disposal sites have unrestricted access and are located within communities. We hypothesize that vector proliferation and exposure to chronic low-level emissions will increase morbidity in children living around such sites. Self-reported disease frequency questionnaires were used to estimate the frequency of new episodes of intestinal, respiratory and skin infections among exposed children less than 10 years. Data was simultaneously collected for unexposed children of the same age, using the same questionnaire. Data reporting by the parents was done in the first week in each of the 6 months study period. The risk ratios were 3.54 (95% CI, 2.19-5.73, 3.20 (95% CI, 1.34-7.60 and 1.35 (95% CI, 0.75-2.44 for respiratory, intestinal and skin infections respectively. Their respective risk differences were 0.47 (47%, 0.18 (18% and 0.08 (8%. The study revealed that poor treatment and disposal of clinical waste sites enhance morbidity in children living close to such areas. Simple health promotion and intervention programs such as relocating such sites can significantly reduce morbidity.

    The Marfan syndrome, an autosomal dominant connective tissue disorder, is manifested by abnormalities in the cardiovascular, skeletal, and ocular systems. Recently, fibrillin, an elastic-associated microfibrillar glycoprotein, has been linked to the Marfan syndrome, and fibrillin mutations in affected individuals have been documented. In this study, genetic linkage analysis with fibrillin-specific markers was used to establish the prenatal diagnosis in an 11-wk-gestation fetus in a four-generation Marfan kindred. At birth, skeletal changes suggestive of the Marfan syndrome were observed. Reverse transcription-PCR amplification of the fibrillin gene mRNA detected a deletion of 123 bp in one allele in affected relatives. This deletion corresponds to an exon encoding an epidermal growth factor-like motif. Examination of genomic DNA showed a G[yields]C transversion at the +1 consensus donor splice site. 45 refs., 7 figs.

    Split-thickness skin grafting is a common procedure to treat different kinds of wounds. This systematic, multicentre, observational, cross-sectional study of adult patients with split-thickness skin graft (STSG) donor site wounds was conducted to evaluate quality of life (QoL) impairments caused by donor site wounds following split-thickness skin grafting. Therefore, 112 patients from 12 wound centres in Germany were examined based on patient and physician questionnaires as well as a physical examination of the donor site wound. Most indications for skin grafting were postsurgical treatment (n = 51; 42.5%) and chronic wounds (n = 47; 39.2%). European QoL visual analoque scale (EQ VAS) averaged 64.7 ± 23.3, European QoL 5 dimensions (EQ-5D) averaged 77.4 ± 30.0. Wound-QoL (range: 0-4) was rated 0.8 ± 0.8 post-surgery and 0.4 ± 0.6 at the time of survey (on average 21 weeks between the time points). Compared to averaged Wound-QoL scores of chronic wounds donor site-related QoL impairments in split-thickness skin-graft patients were less pronounced. There were significant differences in patient burden immediately after surgery compared to the time of the survey, with medium effect sizes. This supports the hypothesis that faster healing of the donor site wound leads to more favourable patient-reported outcomes. © 2017 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

    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.

    Pressure garment therapy (PGT) is well accepted and commonly used by clinicians in the treatment of burns scars and grafts. The medium to high pressures (24-40 mmHg) in these garments can support scar minimisation, and evidence is well documented for this particular application. However, PGT specifically for burn donor sites, of which a sequela is also scarring, is not well documented. This study protocol investigates the impact of a low pressure (4-6 mmHg) interim garment on donor site healing and scarring. With a primary purpose of holding donor dressings in place, the application of the interim pressure garment (IPG) appears to have been twofold. IPGs for donor sites have involved inconsistent application with a focus on securing wound dressing rather than scar management. However, anecdotal and observational evidence suggests that IPGs also make a difference to some patient's scar outcomes for donor sites. This study protocol outlines a randomised controlled trial designed to test the effectiveness of this treatment on reducing scarring to burn donor sites. This study is a single-centre, single (assessor)-blinded, randomised control trial in patients with burns donor sites to their thighs. Patients will be randomly allocated to a control group (with no compression to donor sites) or to an experimental group (with compression to donor sites) as the comparative treatment. Groups will be compared at baseline regarding the important prognostic indicators: donor site location, depth, size, age, and time since graft (5 days). The IPG treatment will be administered post-operatively (on day 5). Follow-up assessments and garment replacement will be undertaken fortnightly for a period of 2 months. This study focuses on a unique area of burns scar management using a low-pressure tubular support garment for the reduction of donor site scars. Such therapy specifically for donor scar management is poorly represented in the literature. This study was designed to test a

    Background: Numerous dressings for split-thickness skin graft donor sites are commercially available with no conclusive evidence-based consensus regarding the optimal dressing choice. This study was conducted to identify which of 5 commonly used materials promotes wound healing most effectively for use on split-thickness donor sites in comparison with our standard dressing, Xeroform (petrolatum gauze). Methods: Twenty-four partial-thickness wounds were created on the backs of 4 pigs using a dermatome. Wounds (n = 4 per dressing type per pig) were treated with Xeroform, Opsite (polyurethane film), Kaltostat ( calcium sodium alginate), DuoDERM (hydrocolloid), Aquacel (hydrofiber), and Mepilex (silicone foam). Full-thickness skin samples were excised at 3 or 5 days and evaluated histologically for reepithelialization and inflammation. Comparisons also included incidence of infection, ease of use, and cost analyses. Results: DuoDERM elicited the greatest percent reepithelialization (81%) and Mepilex the lowest (33%) after 3 days (P = 0.004). All dressings demonstrated complete reepithelialization except Mepilex (85%) at 5 days. There were no infections and inflammation was mild among all treatments. Mepilex was easiest to use, whereas Aquacel, Kaltostat, and Opsite were most difficult (P = 0.03). Xeroform was most cost-effective and Aquacel most expensive. Combined scoring revealed DuoDERM = Xeroform > Opsite = Mepilex > Kaltostat > Aquacel. Conclusions: DuoDERM and Xeroform were most effective overall. DuoDERM tended to outperform all dressings in reepithelialization at 3 days, while Xeroform was least expensive, easy to use, and demonstrated rapid reepithelialization. These findings suggest that Xeroform may be preferred for use on large donor-site areas. DuoDERM may be more appropriate for small donor sites when healing time is a priority. PMID:25289278

We evaluated HAM as wound dressing for split-thickness skin-graft (STSG donor sites in a swine model (Part A and a clinical trial (Part B. Part A: STSG donor sites in 4 piglets were treated with HAM or a clinically used conventional polyurethane (PU foil (n=8 each. Biopsies were taken on days 5, 7, 10, 20, 40, and 60 and investigated immunohistochemically for alpha-smooth muscle actin (αSMA: wound contraction marker, von Willebrand factor (vWF: angiogenesis, Ki-67 (cell proliferation, and laminin (basement membrane integrity. Part B: STSG donor sites in 45 adult patients (16 female/29 male were treated with HAM covered by PU foam, solely by PU foam, or PU foil/paraffin gauze (n=15 each. Part A revealed no difference in the rate of wound closure between groups. HAM showed improved esthetic results and inhibitory effects on cicatrization. Angioneogenesis was reduced, and basement membrane formation was accelerated in HAM group. Part B: no difference in re-epithelialization/infection rate was found. HAM caused less ichor exudation and less pruritus. HAM has no relevant advantage over conventional dressings but might be a cost-effective alternative.

    Autogenous soft-tissue grafting is a commonly used procedure nowadays in dentistry. However, the prolonged healing time needed for the donor site leads to increase the patient's pain and discomfort. Statin has been observed to be beneficial in reducing bacterial burden, improving epithelization and wound healing. The aim of this study was to evaluate intra-oral topical application of simvastatin/chitosan gel (10 mg/mL) over the palatal donor site following free gingival graft (FGG) procedure. Subjects indicated for FGG procedure were divided into four groups. Group I: Simvastatin suspension (S), group II: simvastatin/chitosan gel (SC), group III: chitosan gel (C), group IV: petroleum gel (P). Treatment was applied three times/day for the following 7 days. Wound healing was evaluated at day 3, 7 and 14 post-surgery. A visual analogue scale (VAS) was used to measure the experienced discomfort at 1, 3, 5, 7 and 14 days. Statistical significant reduction in wound-healing scores was observed after 3 and 7 days for group II compared to other groups (p  = .015). A significant reduction was also observed in VAS score for group II compared to other groups at day 1, 3, 5 and 7. Topical application of S/C gel could be used as a novel therapeutic modality that improved healing and reduced pain in the palatal donor site following FGG procedure.

    Treatment of symptomatic, chronic mesenteric ischemia is indicated to relieve symptoms and prevent acute ischemia and death. Current therapeutic options include endovascular and open surgery. The purpose of this prospective study was to evaluate the results of bypasses to the superior mesenteric artery arising from the infrarenal aorta or infrarenal aortic grafts. From January 1999 to December 2016, 24 consecutive patients with a mean age of 61 years underwent a prosthetic bypass to the superior mesenteric artery. Nine patients (37%) presented with an associated clinically important stenosis of the celiac artery and 10 (42%) of the inferior mesenteric artery. Five patients (21%) received preoperative parenteral nutrition. Four patients (17%) underwent dual antiplatelet treatment. The donor site was the infrarenal aorta in 19 patients (79%) and an infrarenal, Dacron graft was used in 5 (21%). The origin of the bypass was from the distal infrarenal aorta or Dacron graft in 19 patients (79%) and from the proximal infrarenal aorta in 5 patients (21%). The graft material consisted of 7 mm polytetrafluoroethylene in 19 cases (79%) and 7 mm Dacron in 5 cases (21%). A concomitant bypass to the inferior mesenteric artery was performed in 4 patients (17%). The primary end points were postoperative mortality, morbidity, graft infection, late survival, primary patency, and symptom-free rate. The secondary end point was postoperative hemorrhagic complications. No postoperative mortality occurred. Postoperative morbidity included a prolonged postoperative ileus in 4 patients (17%), transitory postoperative increases in serum creatinine concentrations in 3 patients (12%), and myocardial ischemia in 2 patients (8%). No postoperative hemorrhagic complications or graft infection were observed. Overall, the cumulative survival rate was 77% at 60 months. The overall late-patency rate and freedom from recurrence of symptoms were both 87% at 60 months. Infrarenal aorta and

    Skin grafts are used to treat many types of skin defects in children, including burns, traumatic wounds, and revision of scars. The objective of this prospective randomized controlled trial was to compare the effectiveness of three dressing types for pediatric donor sites: foam, hydrofiber, and calcium alginate. Children attending a pediatric Burns & Plastics Service from October 2010 to March 2013, who required a split-skin graft, were recruited to the trial. Patients were randomly assigned to the two experimental groups, foam or hydrofiber, and to the control group, calcium alginate. Data were gathered on the management of exudate, assessment of pain, time to healing, and infection. Fifty-seven children aged 1 to 16 years (mean = 4.9 years) were recruited to the trial. Fifty-six patients had evaluable data and one participant from the control group was lost to follow-up. Most children required skin grafting for a burn injury (78%). The median size of the donor site was 63.50 cm (8-600 cm). There was a statistically significant difference in time to healing across the three dressing groups (x [2, n = 56] = 6.59, P = .037). The calcium alginate group recorded a lower median value of days to healing (median = 7.5 days) compared to the other two groups, which recorded median values of 8 days (hydrofiber) and 9.5 days (foam). The greatest leakage of exudate, regardless of dressing type, occurred on day 2 after grafting. No statistically significant difference was found in leakage of exudate, pain scores, or infection rates across the three groups. Calcium alginate emerged as the optimum dressing for pediatric donor site healing in this trial.

    Full Text Available The infusion of donor lymphocytes transduced with a retroviral vector expressing the HSV-TK suicide gene in patients undergoing hematopoietic stem cell transplantation for leukemia/lymphoma promotes immune reconstitution and prevents infections and graft-versus-host disease. Analysis of the clonal dynamics of genetically modified lymphocytes in vivo is of crucial importance to understand the potential genotoxic risk of this therapeutic approach. We used linear amplification-mediated PCR and pyrosequencing to build a genome-wide, high-definition map of retroviral integration sites in the genome of peripheral blood T cells from two different donors and used gene expression profiling and bioinformatics to associate integration clusters to transcriptional activity and to genetic and epigenetic features of the T cell genome. Comparison with matched random controls and with integrations obtained from CD34(+ hematopoietic stem/progenitor cells showed that integration clusters occur within chromatin regions bearing epigenetic marks associated with active promoters and regulatory elements in a cell-specific fashion. Analysis of integration sites in T cells obtained ex vivo two months after infusion showed no evidence of integration-related clonal expansion or dominance, but rather loss of cells harboring integration events interfering with RNA post-transcriptional processing. The study shows that high-definition maps of retroviral integration sites are a powerful tool to analyze the fate of genetically modified T cells in patients and the biological consequences of retroviral transduction.

    In harvesting skin to cover the defect caused by a burn, a second wound is created, the donor site wound. We propose an alternative method to manage the donor site: taking a split-thickness skin graft (STSG) from a donor site adjacent to the burn wound to be treated, and meshing at a 3:1 ratio to cover both sites at once. The main objective of this study is to evaluate the effectiveness of covering both burn wound and adjacent donor site with the same STSG in elderly and bedridden patients. We retrospectively reviewed the medical records of 6 patients over 60 years old or/and bedridden presenting with a small burn wound who underwent STSG of both burn wound and adjacent donor site between April 2016 and November 2016 in the Department of Plastic Surgery and Burn Treatment at Percy Military Hospital (France). Their data were compared with data of five patients who had undergone the usual STSG procedure during the same period. There was a statistically significant difference between patients who underwent adjacent STSG procedure and those who underwent usual STSG procedure in healing time (days) mean (SD) (7,33 ± 1,03 vs. 16,2 ± 0,83; p = 0,007) and Numeric Rating Scale pain mean (SD) at day 2 (0,33 ± 0,33 vs. 2,4 ± 1,35; p = 0,04). Grafting both acute burn wound and adjacent donor site with the same graft seems to be an easy method to improve healing and minimize pain in the STSG donor site in elderly and bedridden patients.

    The conventional procedure of the sural neuro-fasciocutaneous flap enables the supply of blood and venous drainage by increasing the width of the adipofascial tissue and preserving tiny venous return routes. Moreover, skin graft is a common method for donor site closure, which may lead to some complications and influence the aesthetic appearance. We report modifications for a distally based sural neuro-fasciocutaneous perforator flap and a relaying flap for donor site closure without skin graft. Twelve patients undergoing the modified flap for foot and ankle reconstruction were included in this study between 2014 and 2016. A peroneal-based perforator, a superficial vein, and the vascular axis of the sural nerve were included in the pedicle. A Z-shape skin incision was performed to explore the perforator vessels and a relaying island perforator flap was used to close the donor site. All flaps survived completely without necrosis. The area of the flaps ranged from 16 × 8 cm to 30 × 15 cm. The diameter width of the pedicle ranged from 1.0 to 2.0 cm. A relaying perforator island flap was used in 10 cases for donor site closure and no skin graft was performed. There were no serious donor site complications. All patients were satisfied with the aesthetic outcome postoperatively at the final follow-up. The distally based sural neuro-fasciocutaneous perforator flap is considered a reliable method for foot and ankle reconstruction. The modification for flap pedicle and donor site closure method without skin graft should be recommended. Copyright © 2017. Published by Elsevier Ltd.

    Full Text Available Among the many donor sites for harvesting autologous bone graft, the iliac crest has been the most commonly used. However, for foot and ankle procedures the proximal tibia has gained popularity as an alternative donor site due to its anatomic proximity to the primary surgical site. In this article we evaluated the possible complications associated with harvesting proximal tibia bone graft. Our study showed the low incidence of morbidity in harvesting proximal tibia bone graft, thereby providing a good alternative donor for foot and ankle procedures.

    In the past decade, autologous platelet-rich plasma (PRP) therapy has seen increasingly widespread integration into medical specialties. PRP application is known to accelerate wound epithelialization rates, and may also reduce postoperative wound site pain. Recently, we observed an increase in patient satisfaction following PRP gel (Angel, Cytomedix, Rockville, MD) application to split-thickness skin graft (STSG) donor sites. We assessed all patients known to our university-based hospital service who underwent multiple STSGs up to the year 2014, with at least one treated with topical PRP. Based on these criteria, five patients aged 48.4±17.6 (80% male) were identified who could serve as their own control, with mean time of 4.4±5.1 years between operations. In both therapies, initial dressing changes occurred on postoperative day (POD) 7, with donor site pain measured by Likert visual pain scale. Paired t-tests compared the size and thickness of harvested skin graft and patient pain level, and STSG thickness and surface area were comparable between control and PRP interventions (p>0.05 for all). Donor site pain was reduced from an average of 7.2 (±2.6) to 3 (±3.7), an average reduction in pain of 4.2 (standard error 1.1, p=0.0098) following PRP use. Based on these results, the authors suggest PRP as a beneficial adjunct for reducing donor site pain following STSG harvest. PMID:25623477

PRP application is known to accelerate wound epithelialization rates, and may also reduce postoperative wound site pain. Recently, we observed an increase in patient satisfaction following PRP gel (Angel, Cytomedix, Rockville, MD application to split-thickness skin graft (STSG donor sites. We assessed all patients known to our university-based hospital service who underwent multiple STSGs up to the year 2014, with at least one treated with topical PRP. Based on these criteria, five patients aged 48.4±17.6 (80% male were identified who could serve as their own control, with mean time of 4.4±5.1 years between operations. In both therapies, initial dressing changes occurred on postoperative day (POD 7, with donor site pain measured by Likert visual pain scale. Paired t-tests compared the size and thickness of harvested skin graft and patient pain level, and STSG thickness and surface area were comparable between control and PRP interventions (p>0.05 for all. Donor site pain was reduced from an average of 7.2 (±2.6 to 3 (±3.7, an average reduction in pain of 4.2 (standard error 1.1, p=0.0098 following PRP use. Based on these results, the authors suggest PRP as a beneficial adjunct for reducing donor site pain following STSG harvest.

    An open randomised prospectively controlled trial was performed to assess the healing efficacy, slippage rate and degree of discomfort on removal of calcium alginate and a silicone-coated polyamide net dressing on split skin graft donor sites. Sixteen patients were randomised to the calcium alginate group and 14 to the silicone-coated group. The donor sites were assessed at days 7, 10, 14 and up to day 21. The mean time to healing in the calcium alginate group was 8.75 +\\/- 0.78 days (range 7 to 14 days) compared to 12 +\\/- 0.62 days (range 7 to 16 days) for the silicone-coated group (p < 0.01). Although more silicone-coated dressings slipped (5 versus 1), the difference was not statistically significant. Pain during the first dressing change was assessed using a visual analogue pain scale. Although no significant differences were found between the groups, it was necessary to change the dressing protocol in the silicone-coated arm of the trial after entering the first two patients. Overlaid absorbent gauze adhered to the donor site through the fenestrations in the dressing necessitating the placement of paraffin gauze between the experimental dressing and the overlying cotton gauze. There was one infection in the study, occurring in the alginate group. Based on these results we recommend calcium alginate as the dressing of choice for split skin graft donor sites.

    Impaired or delayed wound healing is a common health problem. However, it remains challenging to predict whether wounds in patients will heal without complication or will have a prolonged healing time. In this study, the authors developed an objective screening tool to assess wound healing using microscopic quantification of reepithelialization in a split-thickness skin graft wound model and used this tool to identify risk factors for defective wound healing. Thirty patients (16 male and 14 female) were included in this prospective study. Anterior thigh skin biopsies from the donor site region of partial-thickness skin grafts were dressed with moisture-retentive dressings, and biopsies were examined on days 0, 2, 5, and 10 postoperatively by microscopy. Images were then transferred to a computer for image analysis and epithelial measurements (epithelial thickness and total reepithelialized surface). The effects of gender, age, body mass index, and smoking behavior on these wound healing parameters were determined. The authors found comparable results for the computer and traditional measure methods. However, the time required to perform the measurements using the semiautomated computer method was less than half the time of the traditional method. Image capturing, enhancing, and analysis with the new method required approximately 2 minutes 30 seconds, whereas the traditional methods took up to 7 minutes per image. The total size of the reepithelialized surface (P = .047) and percentage of the biopsy resurfaced with epithelia (P = .011) at day 10 were both significantly higher in male patients compared with female patients. In patients younger than 55 years, reepithelialized areas were significantly thicker than in patients older than 55 years (P = .008), whereas the size of the reepithelialized surface showed no differences. No significant differences in reepithelialization parameters were found concerning body mass index and smoking behavior. Both male gender and

    This study investigated the strengthening effect of different types of plate and position after osteotomy of the sheep tibia, which is a model for the radial osteocutaneous donor site. Fifty matched pairs of adult sheep tibias were tested in torsion and four-point bending. Firstly, the weakening effect of an osteotomy was compared with the intact bone. Then pairs of bones with an osteotomy were compared with and without reinforcement with different types of 3.5mm plate. The plate was placed in either the anterior (over the defect) or posterior (on the intact cortex) position. In torsion the mean strength of the intact bone was 45% greater than after osteotomy (P=0.02). The reinforced bone was on average 61% stronger than the unreinforced bone (Pbone was 188% greater than after osteotomy (P=0.02). The reinforced bone was on average 184% stronger then the unreinforced bone (P<0.001). The tibia was able to withstand much greater loads in bending. The dynamic compression plate was the strongest reinforcement in both torsion and bending. The position of the plate did not alter the strengthening effect in torsion but the posterior position resisted greater bending loads (P=0.01). This may not be relevant in clinical practice as the radius is likely to fracture first as a result of lower torsional forces.

    Retrograde infections often occur with excessive or incomplete drainage of exudate, or as a result of adherence of dressings to wounds. Dialkylcarbamoyl chloride (DACC) irreversibly binds to bacterial surfaces and physically removes bacteria when dressings are changed. Chlorhexidine acetate-soaked paraffin gauze provides a moist wound-healing environment. We hypothesise that when DACC is combined with chlorhexidine acetate-soaked paraffin gauze, wound healing times decrease. From January 2013 to June 2015, medical records were retrospectively evaluated in 60 patients who underwent split-thickness skin grafts (STSG). Patients were divided into two groups: a 'thick skin group' and a 'thin skin group'. These two groups were further subdivided into a control group, where conventional foam dressings were applied to wounds, and an experimental group, where chlorhexidine acetate-soaked paraffin gauze with DACC was applied (DACC group). We compared the wound healing time between these subgroups. Differences in infected wound healing times were also compared. The Mann-Whitney test was applied to compare wound healing times between groups. Epithelialisation duration was significantly shorter in the DACC group. The control group had longer wound healing times, regardless of wound size. In the thick skin group, the median healing duration was 12 days in the control subgroup, compared with 9.5 days in the DACC subgroup (p=0.049). In the thin skin subgroup, the median healing duration in the control group was 18 days, compared with 10 days in the DACC subgroup (p=0.013). Application of DACC and chlorhexidine acetate-soaked paraffin gauze to skin graft donor sites can shorten healing times and is effective in treating infected wounds.

    To identify the most appropriate, most suitable and most efficient dressing for split-thickness skin graft (STSG) donor sites. Comparing the wound healing rate, pain severity and duration, as well as the dressing change frequency in four randomised patient groups. A single-centre non-blinded randomised controlled trial was carried out during 2010-2014. All patients treated for skin defects/lesions (due to burns, trauma or ulcers) using STSG were included in the study. All patients were randomly allocated in four different donor site treatment groups; polyurethane (PU group, Mepilex); polyurethane with silicone membrane (PUSM group; Mepilex border,); transparent, breathable film (TBF group; Mepitel film) and cotton gauze dressings (CG group) using Excel 2007. We evaluated: wound healing time, pain severity and duration, the frequency of dressing change, donor site re-epithelialisation, donor site complications (signs of inflammation or infection). Patients were assessed on postoperative days: 1, 3, 6, 9, 12, 15, 18 and 21. After random allocation of study participants the number of patients in each group were: PU group n=25; PUSM group n=24; TBF group n=24; CG group n=25. The groups were homogenous according to gender, age, main pathology, donor site area and wound size. The STSG donor site healing time varied from 9 to 21 days. The mean healing time in the CG group was 14.76 days, whereas in the PU, PUSM, and TBF group it was significantly shorter; 12.25 days, 11.63 days and 10 days, respectively. Patients in the TBF group demonstrated the most rapid healing time with 66.7% of STSG donor sites healed by postoperative day 9. The pain duration interval in modern dressing groups (PU, PUSM and TBF groups) was 0-9 days, whereas it was 6-18 day in the CS group. Pain intensity mean on postoperative day 1 was 2.21 in the PU group; 1.67 in the PUSM group; 1.46 in the TBF group and 3.04 in the CG group. The average pain duration in Group PU, PUSM, and TBF was 4.08 days; 2

    Live donor liver transplantation is the predominant form of liver transplantation in India and in most Asian countries. Donor outcome reports are an important source of information to be shared with prospective donors at the time of informed consent. This is the first donor outcome series from India. Analysis of donor characteristics and morbidity of 275 live donors from a single large volume center is documented. Two hundred seventy-five patients donated from November 2009 to October 2014, 144 were women and 131 were men, 180 donated to adults and 95 donated to children. Right lobe donors were majority at 62.2% followed by left lateral segment 28%. Two thirds of the live donors did not have any morbidity; 114 complications were encountered in 85 patients. The complications were graded as per Clavien 5 tier grading and major morbidity (grade III b, grade IV grade V) was 4.36%. Postoperative biliary complication was seen in 3 donors. This large single-center study is the first donor outcome report from India, and the results are comparable to other published donor series. Documentation and regular audit of donor outcomes is important to help improve the safety of donor hepatectomy and to provide a database for informed consent of prospective donors.

    Reconstructive surgery for ischial pressure sore defects presents a challenge because of high rates of recurrence. The aim of this study was to describe the use of inferior gluteal artery (IGA) and posterior thigh perforators in management of ischial pressure sores with limited donor sites. Between September 2005 and 2009, 11 patients (9 male, 2 female) with ischial sores were operated by using IGA and posterior thigh perforator flaps. The data of patients included age, sex, cause of paraplegia, flap size, perforator of flap, previous surgeries, recurrences, complications, and postoperative follow-up. Nine IGA and 5 posterior thigh perforator flaps were used. Six patients presented with recurrent lesions, 5 patients were operated for sacral and contralateral ischial pressure sores previously. In 2 patients, IGA and posterior thigh perforator flaps were used in combination. Patients were followed for an average of 34.3 months. In 2 recurrent cases, readvancement of IGA perforator flap and gluteus maximus myocutaneous flap were treatment of choice. Treatment of patients with recurrent lesions or multiple pressure sores is challenging because of limited available flap donor sites. In this study, posterior thigh perforator flaps were preferred in patients in whom the previous donor site was the gluteal region. IGA perforator flaps were the treatment of choice in patients for whom posterior thigh region was previously used. Alternately, preserved perforators of previous conventional myocutaneous flaps enabled us to use these perforators in recurrences.

    Split-thickness skin graft is one of the most used procedures in plastic surgery. This procedure involves numerous painful dressings at the donor site. α-Tocopherol acetate has anti-oxidative and anti-inflammatory properties and it can reduce the local bacterial growth, thereby promoting wound healing. We designed a prospective study to evaluate the effects of two different kinds of dressings at skin graft donor sites. A total of 30 patients were subjected to daily dressings with α-tocopherol acetate oil and traditional moist gauzes (group 1). Another 30 patients were subjected to dressings every 4 days with α-tocopherol acetate oil and silicone-vitamin E gauzes (group 2). Healing time, infection rate, patient's pain perception and costs were evaluated in both the groups. No statistically significant difference was found in terms of healing time. The infection rate was slightly different in the two groups. Significant reduction of pain perception was detected in group 2. In the same group, significant reduction in the total cost of the treatment was also observed. α-Tocopherol acetate oil and silicone-vitamin E gauzes may represent a safe, simple, painless and inexpensive method for improving skin graft donor site healing. © 2017 The Authors.

    To compare postoperative healing of split-thickness skin graft (STSG) donor sites using traditional dressings (paraffin gauze) or modern wound dressings (alginate dressing and polyurethane film) in a randomized controlled trial. Thirty patients were randomly assigned to treatment of an STSG donor site with an alginate dressing and a polyurethane film or nonadherent paraffin gauze. Outcome variables were pain (measured with a visual analog scale), amount of dressing changes, healing time, cosmetic outcome, treatment costs, and overall satisfaction with the procedure. There was no significant difference in pain (postoperative day 1: 2.1 vs 1.2, P = .26; postoperative days 5-7: 1.0 vs 0.9, P = .47; final removal: 1.9 vs 1.0, P = .19) and time to healing (18.1 vs 15.4 days, P = .29) between alginate/polyurethane film dressing and nonadherent paraffin gauze. The semiocclusive dressings with polyurethane film required multiple dressing changes, whereas the nonadherent paraffin gauze could be left in place until complete epithelialization. Treatment costs were substantially lower for paraffin gauze. Semiocclusive dressings with alginate dressings and polyurethane film showed no advantages over treatment with paraffin gauze. With lower costs and better patient acceptance, paraffin gauze dressings were the preferred treatment for STSG donor sites.

    Most pharmacokinetic (PK) models used for propofol administration are based on studies in normal-weight patients. Extrapolation of these models for morbidly obese patients is controversial. Using 2 PK models and a target-controlled infusion system, we determined the predicted propofol effect-site concentration (Ce) needed for induction of anesthesia in morbidly obese subjects using total body weight. Sixty-six morbidly obese subjects from 18 to 50 years of age were randomized to receive propofol to reach and maintain a predetermined propofol Ce, based on the PK models of either Marsh or Schnider. All patients were monitored with a Bispectral Index electroencephalographic monitor. Fentanyl 3 μg/kg total body weight was administered before starting the propofol infusion. After loss of consciousness, vecuronium was administered to facilitate endotracheal intubation. Groups of 6 patients each received propofol at a different, predetermined target propofol Ce. An "effective Ce" (ECe) was defined as the propofol Ce that provided adequate hypnosis (Bispectral Index <60) during the complete induction period (45 seconds after reaching the predetermined target Ce until 5 minutes after tracheal intubation). Heart rate and arterial blood pressure were measured every 1 minute throughout the study period. Probit regression analysis was performed to calculate the effective propofol Ce values to induce hypnosis in 50% (ECe(50)) and 95% (ECe(95)) of patients with 95% confidence intervals (CIs). Patient characteristics were similar between models and across the propofol target concentration groups. The ECe(50) of propofol was 3.4 μg/mL (95% CI: 2.9, 3.7 μg/mL) with the Marsh model and 4.5 μg/mL (95% CI: 4.1, 4.8 μg/mL) with the Schnider model (P < 0.001). The ECe(95) values were 4.2 μg/mL (95% CI: 3.8, 6.2 μg/mL) and 5.5 μg/mL (95% CI: 5.0, 7.2 μg/mL) with Marsh and Schnider models, respectively. At the ECe(95), hemodynamic effects were similar with the 2 PK models

    This study was done to determine the impact of the method of placental removal and the site of uterine repair on postcesarean infectious morbidity rates in women receiving prophylactic antibiotics at cesarean delivery. This prospective study included 284 women who underwent cesarean delivery and who were randomly assigned to four groups based on the method of placental removal and the site of uterine repair: group 1, spontaneous placental removal and in situ uterine repair; group 2, spontaneous placental removal and exteriorized uterine repair; group 3, manual placental removal and in situ uterine repair; and group 4, manual placental removal with exteriorized uterine repair. Exclusion criteria were repeat cesarean deliveries without labor, active infection at the time of cesarean delivery, and patient refusal to participate. There was no significant difference among the groups in maternal age, race, parity, weight, the length of time from rupture of membranes (ROM) or the number of vaginal examinations from ROM to cesarean delivery, or preoperative hematocrit. Intraoperatively, the type of uterine incision, anesthesia administered, incidence of meconium-stained amniotic fluid, Apgar scores, and cord gases were similar between groups. The incidence of postcesarean endometritis was greater in group 4 (32 [45 percent] of 71, p = 0.003) compared with group 1 (17 [24 percent] of 71), group 2 (12 [30 percent] of 71); and group 3 (13 [18 percent] of 71). Manual placental removal and exteriorization of the uterus for repair of the surgical incision increases the infectious morbidity rate in women receiving prophylactic antibiotics at the time of cesarean delivery and increases the length of hospitalization.

    Whether the composition of palatal connective tissue grafts (CTGs) varies depending on donor site or harvesting technique in terms of relative amounts of fibrous connective tissue (CT) and fatty/glandular tissue (FGT) is currently unknown and is histologically assessed in the present study. In 10 fresh human cadavers, tissue samples were harvested in the anterior and posterior palate and in areas close to (marginal) and distant from (apical) the mucosal margin. Mucosal thickness, lamina propria thickness (defined as the extent of subepithelial portion of the biopsy containing ≤25% or ≤50% FGT), and proportions of CT and FGT were semi-automatically estimated for the entire mucosa and for CTGs virtually harvested by split-flap (SF) preparation minimum 1 mm deep or after deepithelialization (DE). Palatal mucosal thickness, ranging from 2.35 to 6.89 mm, and histologic composition showed high interindividual variability. Lamina propria thickness (P >0.21) and proportions of CT (P = 0.48) and FGT (P = 0.15) did not differ significantly among the donor sites (anterior, posterior, marginal, apical). However, thicker palatal tissue was associated with higher FGT content (P tissue composition in the hard palate, DE-harvested CTG contains much larger amounts of CT and much lower amounts of FGT than SF-harvested CTG, irrespective of the harvesting site.

    A prospective, randomized, placebo-controlled clinical trial was conducted to compare the healing effectiveness of Alkanna tinctoria (L.) Tausch (Boraginaceae) with standard dressing on wound healing at the donor site after removal of the skin graft. Enrolled patients were randomly allocated to receive topicalA. tinctoria extract ointment (20%) or standard dressing (dressing with base ointment) daily. Wound healing was assessed using the Bates-Jenson assessment tool at the 2 nd and 4 th weeks after intervention. Decreases in wound score were significantly greater in the A. tinctoria group compared with the placebo group (P <0.05). The surface areas of graft donor sites in the A. tinctoria group were significantly reduced as compared with the control group at day 28 of the intervention (P < 0.05). The proportion of patients in the A. tinctoria group achieving complete wound healing within 2 to 4 weeks was 50% and 96.66%, respectively, significantly higher than in patients receiving standard care: 0% and 23.3%, respectively. This clinical study showed that A. tinctoria dressing accelerates wound healing after graft harvesting. IRCT ID: IRCT201511165781N2 .

    Platelet-rich plasma (PRP) contains multiple growth factors, and fragmin-protamine micro-nanoparticles (F-P M-NPs) significantly enhance and stabilize growth factors. The purpose of this study was to evaluate the effects of PRP-containing F-P M-NPs (PRP&F-P M-NPs) on wound repair in split-thickness skin graft (STSG-) donor sites (DS). A total of 56 inbred male rats were anesthetized and split-thickness skin graft donor site (STSG-DS) were created with a Padgett dermatome. PRP&F-P M-NPs, F-P M-NPs, PRP, and saline (control) were then intradermally injected evenly into the STSG-DSs. On 3, 4, 5, 7, and 10 d after creation of STSG-DS, skin sample sections were stained with hematoxylin and eosin to evaluate reepithelialization and angiogenesis. Treatment of STSG-DS with PRP&F-P M-NPs effectively promoted epithelialization and new vessel formation compared with those treated with PRP, F-P M-NPs, and control (saline). The intradermal injection of PRP&F-P M-NPs promotes epithelialization and angiogenesis in STSG-DS wounds. Copyright © 2015 Elsevier Inc. All rights reserved.

    Skin graft is a standard therapeutic technique in patients with deep ulcers, but managing donor site after grafting is very important. Although several modern dressings are available to enhance the comfort of donor site, using techniques that accelerate wound healing may enhance patient satisfaction. Low-level laser therapy (LLLT) has been used in several medical fields, including healing of diabetic, surgical, and pressure ulcers, but there is not any report of using this method for healing of donor site in burn patients. The protocols and informed consent were reviewed according to Medical Ethics Board of Shahid Beheshti University of Medical Sciences (IR.SBMU.REC.1394.363) and Iranian Registry of Clinical Trials (IRCT2016020226069N2). Eighteen donor sites in 11 patients with grade 3 burn ulcer were selected. Donor areas were divided into 2 parts, for laser irradiation and control randomly. Laser area was irradiated by a red, 655-nm laser light, 150 mW, 2 J/cm 2 , on days 0 (immediately after surgery), 3, 5, and 7. Dressing and other therapeutic care for both sites were the same. The patients and the person who analyzed the results were blinded. The size of donor site reduced in both groups during the 7-day study period (P < 0.01) and this reduction was significantly greater in the laser group (P = 0.01). In the present study, for the first time, we evaluate the effects of LLLT on the healing process of donor site in burn patients. The results showed that local irradiation of red laser accelerates wound healing process significantly.

    Due to the similarity of keratinized gingival and palatal mucosa the latter can pose as a potential donor site for gingival recession coverage. However, its availability is restricted and a thin transplant bears the risk of being rejected. The aim of the present study was to compare the clinical and histological results of thin palatal mucosa augmentation, using lyophilized Biokol ® xenogenous collagen sponge and a suspension of xenogenous Gel 0 ® pure collagen with non-augmented tissue from the same patients. Ten patients simultaneously underwent bilateral augmentation procedures using Biokol ® and Gel 0 ® collagen material. The donor sites were augmented 8 weeks prior to the harvesting of the connective tissue graft (CTG) for the gingival recession coverage procedures. Prior to the implantation of the collagen material and during the course of harvesting the augmented CTG, tissue specimens were taken for histological examination. Prior to the commencement of the study and after it, the parameters of palatal gingival thickness at 4mm (PGT1), and at 8mm apical to the gingival margin (PGT2) around the teeth neighboring the operating fields were determined. In both groups the palatal mucosa had thickened significantly in both measuring sites. An intergroup comparison revealed greater thickening of the masticatory mucosa in the Biokol ® group at both measuring points. The histological image of the grafts, obtained from sites augmented using both test methods, revealed a typical pattern of mature fibrous connective tissue. No epithelial cells were found. Augmentation of thin masticatory mucosa using Biokol ® or Gel 0 ® collagen materials resulted in a significant thickening of the mucosa, which could be demonstrated to be greater in the first group.

    Full Text Available Background Latissimus dorsi (LD myocutaneous flap is a popular method of breastreconstruction which can be associated with high incidence of seroma formation. Quiltingsutures at the harvest site are used to reduce this. Barbed sutures are self anchoring sutureswhich avoid multiple knotting and can be useful in quilting.Methods A retrospective analysis of prospectively maintained database of patients whounderwent LD flap breast reconstruction between January 2009 and January 2011 was carriedout. Seroma formation at the harvest site, wound related complications, inpatient stay andduration of surgery were analysed and a comparison was made between two groups wherequilting was done with barbed (V-Loc suture and conventional polydioxanone (PDS II sutures.Results Fifty-seven patients were included of which 33 had quilting by V-Loc sutures and in24 patients PDS II suture was used. Median age in the PDS group was 55 years (interquartilerange [IQR], 45 to 61 years which was comparable to the V-Loc group (53 years [IQR, 48to 59 years]; P-value 0.948. Sixteen patients (28% had significant seroma formation and5 (9% patients developed superficial wound dehiscence. Incidences of seroma or woundcomplications were comparable (P-value 0.378 and 1.00, respectively. Secondary outcomessuch as total duration of surgery, total inpatient stay, total amount of drain at the donor sitewere also similar in two groups.Conclusions Use of barbed sutures for quilting the donor site in LD flap reconstruction is afeasible option and the associated seroma formation and wound complications are comparablewith conventional sutures.

    Full Text Available Nonmyeloablative allogeneic stem cell transplantation (SCT can induce remission in patients with renal cell carcinoma (RCC, but this graft-versus-tumor (GVT effect is often accompanied by graft-versus-host disease (GVHD. Here, we evaluated minor histocompatibility antigen (MiHA-specific T cell responses in two patients with metastatic RCC who were treated with reduced-intensity conditioning SCT followed by donor lymphocyte infusion (DLI. One patient had stable disease and emergence of SMCY.A2-specific CD8+ T cells was observed after DLI with the potential of targeting SMCY-expressing RCC tumor cells. The second patient experienced partial regression of lung metastases from whom we isolated a MiHA-specific CTL clone with the capability of targeting RCC cell lines. Whole genome association scanning revealed that this CTL recognizes a novel HLA-B7-restricted MiHA, designated ZAPHIR, resulting from a polymorphism in the splice donor site of the ZNF419 gene. Tetramer analysis showed that emergence of ZAPHIR-specific CD8+ T cells in peripheral blood occurred in the absence of GVHD. Furthermore, the expression of ZAPHIR in solid tumor cell lines indicates the involvement of ZAPHIR-specific CD8+ T cell responses in selective GVT immunity. These findings illustrate that the ZNF419-encoded MiHA ZAPHIR is an attractive target for specific immunotherapy after allogeneic SCT.

    Drainage of peatlands for agriculture, forestry and peat extraction turned these landscapes into hotspots of greenhouse gas emissions. Climate protection now fosters rewetting projects to restore the natural peatland function as a sink of atmospheric carbon. One possible way to combine ecological and economical goals is Sphagnum farming, i.e. the cultivation of Sphagnum mosses as high-quality substrates for horticulture. This project scientifically evaluates the attempt of commercial Sphagnum farming on former peat extraction sites in north-western Germany. The exchange of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) of the whole peatland-based production chain comprising a donor mire, a propagation area, an irrigation polder and a cultivation site will be determined in a high temporal resolution for two years using manual chambers. This will allow evaluating the greenhouse gas balance of Sphagnum farming sites in comparison to near-natural sites and the potential of Sphagnum farming for restoring drained peatlands to sinks of atmospheric carbon. The influence of different irrigation techniques will also be tested. Additionally, selected plots will be equipped with open top chambers in order to examine the greenhouse gas exchange under potential future climate change conditions. Finally, a 13C pulse labeling experiment will make it possible to trace the newly sequestered CO2 in biomass, soil, respiration and dissolved organic carbon.

    This prospective, randomised study compares a new transforming methacrylate dressing (TMD) with a silver-containing carboxymethylcellulose dressing (CMC-Ag) after application to split-thickness skin graft (STSG) donor sites. This was an unblinded, non-inferiority, between-patient, comparison study that involved patients admitted to a single-centre burn unit who required two skin graft donor sites. Each patient's donor sites were covered immediately after surgery: one donor site with TMD and the other with CMC-Ag. The donor sites were evaluated until healing or until 24 days post-application, whichever came first. Study endpoints were time to healing, daily pain scores, number of dressing changes, patient comfort and physicians' and patients' willingness to use the dressings in the future. Nineteen patients had both the dressings applied. No statistically significant difference was noted in time to healing between the two dressings (14·2 days using TMD compared with 13·2 days using CMC-Ag). When pain scores were compared, TMD resulted in statistically significantly less pain at three different time periods (2-5 days, 6-10 days and 11-15 days; P < 0·001 at all time periods). Patients also reported greater comfort with TMD (P < 0·001). Users rated TMD as being less easy to use because of the time and technique required for application. Reductions in pain and increased patient comfort with the use of the TMD dressing, compared with CMC-Ag, were seen as clinical benefits as these are the major issues in donor site management. © 2013 The Authors.

  12. Use of autologous bone graft in anterior cervical decompression: morbidity & quality of life analysis.

    LENUS (Irish Health Repository)

    Heneghan, Helen M

    2009-01-01

    BACKGROUND: Autologous iliac crest graft has long been the gold standard graft material used in cervical fusion. However its harvest has significant associated morbidity, including protracted postoperative pain scores at the harvest site. Thus its continued practice warrants scrutiny, particularly now that alternatives are available. Our aims were to assess incidence and nature of complications associated with iliac crest harvest when performed in the setting of Anterior Cervical Decompression (ACD). Also, to perform a comparative analysis of patient satisfaction and quality of life scores after ACD surgeries, when performed with and without iliac graft harvest. METHODS: All patients who underwent consecutive ACD procedures, with and without the use of autologous iliac crest graft, over a 48 month period were included (n = 53). Patients were assessed clinically at a minimum of 12 months postoperatively and administered 2 validated quality of life questionnaires: the SF-36 and Cervical Spine Outcomes Questionnaires (Response rate 96%). Primary composite endpoints included incidence of bone graft donor site morbidity, pain scores, operative duration, and quality of life scores. RESULTS: Patients who underwent iliac graft harvest experienced significant peri-operative donor site specific morbidity, including a high incidence of pain at the iliac crest (90%), iliac wound infection (7%), a jejunal perforation, and longer operative duration (285 minutes vs. 238 minutes, p = 0.026). Longer term follow-up demonstrated protracted postoperative pain at the harvest site and significantly lower mental health scores on both quality of life instruments, for those patients who underwent autologous graft harvest CONCLUSION: ACD with iliac crest graft harvest is associated with significant iliac crest donor site morbidity and lower quality of life at greater than 12 months post operatively. This is now avoidable by using alternatives to autologous bone without compromising clinical

  13. Biogeochemical Modeling of In Situ U(VI) Reduction and Immobilization with Emulsified Vegetable Oil as the Electron Donor at a Field Site in Oak Ridge, Tennessee

    A comprehensive biogeochemical model was developed to quantitatively describe the coupled hydrologic, geochemical and microbiological processes that occurred following injection of emulsified vegetable oil (EVO) as the electron donor to immobilize U(VI) at the Oak Ridge Integrated Field Research Challenge site (ORIFRC) in Tennessee. The model couples the degradation of EVO, production and oxidation of long-chain fatty acids (LCFA), glycerol, hydrogen and acetate, reduction of nitrate, manganese, ferrous iron, sulfate and uranium, and methanoganesis with growth of multiple microbial groups. The model describes the evolution of geochemistry and microbial populations not only in the aqueous phase as typically observed, but also in the mineral phase and therefore enables us to evaluate the applicability of rates from the literature for field scale assessment, estimate the retention and degradation rates of EVO and LCFA, and assess the influence of the coupled processes on fate and transport of U(VI). Our results suggested that syntrophic bacteria or metal reducers might catalyze LCFA oxidation in the downstream locations when sulfate was consumed, and competition between methanogens and others for electron donors and slow growth of methanogen might contribute to the sustained reducing condition. Among the large amount of hydrologic, geochemical and microbiological parameter values, the initial biomass, and the interactions (e.g., inhibition) of the microbial functional groups, and the rate and extent of Mn and Fe oxide reduction appear as the major sources of uncertainty. Our model provides a platform to conduct numerical experiments to study these interactions, and could be useful for further iterative experimental and modeling investigations into the bioreductive immobiliztion of radionuclide and metal contaminants in the subsurface.

    Lynch syndrome is an autosomal dominantly inherited disease that is characterized by a predisposition to cancers, mainly colorectal cancer. Germline mutations of DNA mismatch repair genes such as MLH1, MSH2, MSH6 and PMS2 have been described in patients with Lynch syndrome. Here, we report deletion of 2 bp in the splice donor site of the MLH1 exon 6 (c.545+4_545+5delCA) in a 48-year-old Japanese woman with Lynch syndrome. RT-PCR direct sequencing analysis revealed that this mutation led to an increase in the level of an MLH1 transcript in which exon 6 was skipped, and may cause a frameshift (p.E153FfsX8). Therefore, this mutation appears to be pathogenic and is responsible for Lynch syndrome. Additionally, analysis of the patient's tumor cells indicated microsatellite instability high phenotype and loss of the MLH1 and PMS2 proteins. To our knowledge, this is a germline splice site mutation of MLH1 that has not been reported previously. © The Author 2015. Published by Oxford University Press. All rights reserved.

    Galactosemia affects 1/84,000 in Sweden and is manifested in infancy when the child is exposed to galactose in the diet. If untreated there is a risk of severe early symptoms and, even with a lactose-free diet, late symptoms such as mental retardation and ovarial dysfunction may develop. In classical galactosemia, galactose-1-phosphate uridyltransferase (GALT) (EC 2.7.7.12) is defective and the normal cDNA sequence of this enzyme has been characterized. Recently eight mutations leading to galactosemia were published. Heparinized venous blood was drawn from a patient with classical galactosemia. In the cDNA from the patient examined, an insertion of 54 bp was found at position 1087. Amplification of the relevant genomic region of the patient's DNA was performed. Exon-intron boundaries and intronic sequences thus determined revealed that the 54-bp insertion was located immediately downstream of exon 10. It was further found that the patient was heterozygous for a point mutation, changing a C to a T (in 5 of 9 clones) at the second base in the intron downstream of the insertion. This alteration creates a sequence which, as well as the ordinary splice site, differs in only two positions from the consensus sequence. It was found that the mutation occurred in only one of the 20 alleles from galactosemic patients and in none of the 200 alleles from normal controls. The mutation is inherited from the mother, who also was found to express the 54-bp-long insertion at the mRNA level. Sequences from the 5[prime] end of the coding region were determined after genomic amplification, revealing a sequence identical to that reported. The mutation on the paternal allele has not been identified. 9 refs., 1 fig.

    To report a heterozygous female presenting with an early-onset and severe form of X-linked retinitis pigmentosa (XLRP). This is a case series presenting the clinical findings in a heterozygous female with XLRP and two of her family members. Fundus photography, fundus autofluorescence, ocular coherence tomography, and visual perimetry are presented. The proband reported here is a heterozygous female who presented at the age of 8 years with an early onset and aggressive form of XLRP. The patient belongs to a four-generation family with a total of three affected females and four affected males. The patient was initially diagnosed with retinitis pigmentosa (RP) at the age of 4 years. Genetic testing identified a heterozygous donor splice site mutation in intron 1 (IVS1 + 1G > A) of the retinitis pigmentosa GTPase regulator gene. The father of the proband was diagnosed with RP when he was a young child. The sister of the proband, evaluated at the age of 6 years, showed macular pigmentary changes. Although carriers of XLRP are usually asymptomatic or have a mild disease of late onset, the proband presented here exhibited an early-onset, aggressive form of the disease. It is not clear why some carrier females manifest a severe phenotype. A better understanding of the genetic processes involved in the penetrance and expressivity of XLRP in heterozygous females could assist in providing the appropriate counseling to affected families.

  17. On the influence of X-ray surface radiation of the donor or recipient site on the revascularisation of autologous free full thickness skin grafts

    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.

    Mutations in the gene that encodes CDGSH iron sulfur domain 2 (CISD2) are causative of Wolfram syndrome type 2 (WFS2), a rare autosomal recessive neurodegenerative disorder mainly characterized by diabetes mellitus, optic atrophy, peptic ulcer bleeding and defective platelet aggregation. Four mutations in the CISD2 gene have been reported. Among these mutations, the homozygous c.103 + 1G > A substitution was identified in the donor splice site of intron 1 in two Italian sisters and was predicted to cause a exon 1 to be skipped. Here, we employed molecular assays to characterize the c.103 + 1G > A mutation using the patient's peripheral blood mononuclear cells (PBMCs). 5'-RACE coupled with RT-PCR were used to analyse the effect of the c.103 + 1G > A mutation on mRNA splicing. Western blot analysis was used to analyse the consequences of the CISD2 mutation on the encoded protein. We demonstrated that the c.103 + 1G > A mutation functionally impaired mRNA splicing, producing multiple splice variants characterized by the whole or partial absence of exon 1, which introduced amino acid changes and a premature stop. The affected mRNAs resulted in either predicted targets for nonsense mRNA decay (NMD) or non-functional isoforms. We concluded that the c.103 + 1G > A mutation resulted in the loss of functional CISD2 protein in the two Italian WFS2 patients.

    As the use of fecal microbiota transplantation (FMT) has gained momentum, an increasing need for continuous access to healthy feces donors has developed. Blood donors constitute a healthy subset of the general population and may serve as an appropriate group for recruitment. In this study, we...... investigated the suitability of blood donors as feces donors. In a prospective cohort study, we recruited blood donors onsite at a public Danish blood bank. Following their consent, the blood donors underwent a stepwise screening process: First, blood donors completed an electronic pre-screening questionnaire...... to rule out predisposing risk factors. Second, eligible blood donors had blood and fecal samples examined. Of 155 blood donors asked to participate, 137 (88%) completed the electronic pre-screening questionnaire, 16 declined, and 2 were excluded. Of the 137 donors who completed the questionnaire, 79 (58...

    Closure of the donor site on the index finger after raising a first dorsal metacarpal artery (DMA) flap harvest is challenging. The conventional choice is to use a full-thickness skin graft. However, this procedure is associated with several complications and a second donor site to harvest the skin graft is inevitable. The aim of this study was to design a modified incision to allow harvest of a first DMA flap without skin graft. From 2015 to 2016, 18 patients with a soft tissue defect of the thumb had reconstruction of the defect using a first DMA flap. A modified incision was used and a relaying perforator flap pedicled on the second DMA was raised through the same incision to cover the donor site. Patient satisfaction, appearance of the injured hand, and the active range of motion (ROM) were assessed. The sensitivity was evaluated by the 2-point discrimination (2-PD) test. All flaps survived completely without complications. Good coverage was obtained with only one linear scar in the dorsum of the hand and no skin grafts. All patients recovered full range of movement in their fingers and regained sensitivity of the flaps. All patients were satisfied with their hand function according to the Michigan Hand Outcomes Questionnaire (MHQ). The mean cosmetic score for the appearance of the injured hand was 8.2 out of 10. Using our modified incision, it was possible to harvest a second DMA flap at the same time as a first DMA flap allowing simultaneous coverage of the donor defect on the index finger. This prevented the need for a skin graft with all of the associated disadvantages. Copyright © 2018. Published by Elsevier Ltd.

    The properties of serum albumin obtained from donors and from paranoid schizophrenia patients were studied with the fluorescent probe K-35 (N-carboxyphenylimide of dimethylaminonaphthalic acid) and time-resolved fluorescence spectroscopy on the SR beam station of the S-60 synchrotron of the Lebedev Physical Institute. The mean fluorescence quantum yield of K-35 in patients serum was decreased significantly by 25-60% comparing with donors. The analysis of pre-exponential factors of fluorescence decay using 'amplitude standard' method has shown that in patient sera the fraction of K-35 molecules bound with albumin and inaccessible to fluorescence quenchers ('bright' K-35 molecules with {tau}{sub 1}=8.0{+-}0.4 ns) is 1.2-3 times less than in the donor sera. The fraction of K-35 molecules with partly quenched fluorescence ({tau}{sub 2}=1.44{+-}0.22 ns) was significantly increased in schizophrenia patients. The results obtained suggest that the properties of binding region in serum albumin molecules of acute paranoid schizophrenia patients change significantly.

    DNA from a patient with severe hemophilia B was evaluated by RFLP analysis, producing results which suggested the existence of a partial deletion within the factor IX gene. The deletion was further localized and characterized by PCR amplification and sequencing. The altered allele has a 4,442-bp deletion which removes both the donor splice site located at the 5[prime] end of intron d and the two last coding nucleotides located at the 3[prime] end of exon IV in the normal factor IX gene; this fragment has been inserted in inverted orientation. Two homologous sequences have been discovered at the ends of the deleted DNA fragment.

    Full Text Available Renal transplantation has profound improvements in mortality, morbidity, and overall quality of life compared to renal replacement therapy. This report aims to illustrate the use of ex-vivo partial nephrectomy in a patient with a renal angiomyolipoma prior to living donor transplantation. The surgical outcomes of the donor nephrectomy and recipient transplantation are reported with 2 years of follow-up. Both the donor and recipient are healthy and without any significant comorbidities. In conclusion, urologic techniques such as partial nephrectomy can be used to expand the living donor pool in carefully selected and well informed transplant recipients. Our experience demonstrated a safe and positive outcome for both the recipient and donor, and is consistent with other reported outcomes in the literature.

  8. Expanding the live kidney donor pool: ethical considerations regarding altruistic donors, paired and pooled programs.

    2011-06-01

    In renal transplant, there is a well-known deficiency in organ supply relative to demand. Live donation provides superior results when compared with deceased donation including a better rate of graft success and fewer immunologic complications. This deficiency in organs leads to significant morbidity and mortality rates. Alternative avenues have been extensively explored that may expand the live donor pool. They include altruistic donation as well as paired and pooled exchange programs. Altruistic donation is a truly selfless act from a donor unknown to the recipient. Kidney paired donation involves 2 incompatible donor-recipient pairs swapping donors to produce compatibility. Pooled donation involves at least 2 pairs, and can take the form of domino chains in which altruistic input sets up a chain of transplants, in which each recipient's incompatible donor makes a donation for the next recipient. Despite application of these various methods, there lie extensive ethical issues surrounding them. Misconceptions frequently occur; for instance, the perceived benefit that donating an organ to a loved one is greater for a related donor than for an altruistic one. Additionally, it is frequently believed that immunologic incompatibility offers coerced donors liberation from surgery, and that overcoming these barriers by introducing exchange programs provides vulnerable donors less protection. This article explores these and other complex ethical issues surrounding the various methods of expanding the donor pool. The authors offer opinions that challenge the ethical issues and attempt to overcome those views that hinder progress in the field.

    Objective: To share experience of live donor nephrectomy (including intraoperative variables, morbidity and ethical aspects) and to give an overview of surgical technique being practiced. Results: Majority of the donors (58.5%) were 31-50 years old and 70.6% were first-degree relatives. Left sided kidney was taken in 96.5% cases. Mean operative time was 145 minutes. Mean renal warm ischemia time from cross clamping of renal vessels to cold perfusion on the bench was 1.5 minutes per operation. Operative complications encountered were injury to lumbar veins in 5.1 % cases, slipping of satinsky clamp on vena cava stump in 1.7 % and accidental pleural damage in 5.1 % cases. Postoperative morbid complications found were urinary retention in 6.4 % cases, epididymo-orchitis in 1.7 %, prolonged lymph drain in 3.4 %, stitch infection in 1.7 % and prolonged wound discomfort in 5.1 % patients. Conclusions: Open live donor nepherectomy appears to be safe procedure for harvesting kidney. Related or emotionally related donors must be the choice in all cases. Non-related donors may be entertained in selected cases despite the probability of organ vending in our society. (author)

    While laparoscopic donor nephrectomy has encouraged living kidney donation, debate exists about the safest laparoscopic technique. We compared purely laparoscopic and hand assisted laparoscopic donor nephrectomies in terms of donor outcome, early graft function and long-term graft outcome. We reviewed the records of consecutive laparoscopic and hand assisted laparoscopic donor nephrectomies performed by a single surgeon from 2002 to 2011. Donor operative time and perioperative morbidity were compared. Early graft function for kidneys procured by each technique was evaluated by rates of delayed graft function, need for dialysis and recipient discharge creatinine. Long-term outcomes were evaluated by graft function. A total of 152 laparoscopic donor nephrectomies were compared with 116 hand assisted laparoscopic donor nephrectomies. Hand assisted procedures were more often done for the right kidney (41.1% vs 17.1%, p recipient outcomes were also similar. Delayed function occurred after 0% hand assisted vs 0.9% purely laparoscopic nephrectomies, dialysis was required in 0.9% vs 1.7% and rejection episodes developed in 9.7% vs 18.4% (p >0.05). At last followup the organ was nonfunctioning in 6.1% of hand assisted and 7.7% of purely laparoscopic cases (p >0.05). The recipient glomerular filtration rate at discharge home was similar in the 2 groups. Hand assisted laparoscopic donor nephrectomy had shorter warm ischemia time but perioperative donor morbidity and graft outcome were comparable. The choice of technique should be based on patient and surgeon preference. Copyright © 2013 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

    Acetylene separation is a very important but challenging industrial separation task. Here, through the solvothermal reaction of CuI and 5-triazole isophthalic acid in different solvents, two metal-organic frameworks (MOFs, FJU-21 and FJU-22) with open O donor sites and controllable robustness have been obtained for acetylene separation. They contain the same paddle-wheel {Cu2(COO2)4} nodes and metal-ligand connection modes, but with different helical chains as secondary building units (SBUs), leading to different structural robustness for the MOFs. FJU-21 and FJU-22 are the first examples in which the MOFs' robustness is controlled by adjusting the helical chain SBUs. Good robustness gives the activated FJU-22 a, which has higher surface area and gas uptakes than the flexible FJU-21 a. Importantly, FJU-22 a shows extraordinary separation of acetylene mixtures under ambient conditions. The separation capacity of FJU-22 a for 50:50 C2H2/CO2 mixtures is about twice that of the high-capacity HOF-3, and its actual separation selectivity for C2H2/C2H4 mixtures containing 1 % acetylene is the highest among reported porous materials. Based on first-principles calculations, the extraordinary separation performance of C2H2 for FJU-22 a was attributed to hydrogen-bonding interactions between the C2H2 molecules with the open O donors on the wall, which provide better recognition ability for C2H2 than other functional sites, including open metal sites and amino groups. © 2016 WILEY-VCH Verlag GmbH & Co.

    With rapid increase in the usage of social networks sites across the world, there is also a steady increase in blood donation requests as being noticed in the number of posts on these sites such as Facebook and twitter seeking blood donors. Finding blood donor is a challenging issue in almost every country. There are some blood donor finder applications in the market such as Blood app by Red Cross and Blood Donor Finder application by Neologix. However, more reliable applications that meet the needs of users are prompted. Several software technologies including languages and framework are used to develop our blood-donor web application known as BLOODR application. These technologies comprise Ruby programming language (simply known as Ruby) along with JavaScript and PostgreSQL for database are used. Ruby on Rails (simply known as Rails) is an open source Web framework that makes it possible to quickly and easily create data-based web applications. We show screenshots for the BLOODR application for different types of users including requester, donor, and administrator. Various features of the application are described and their needs of use are analyzed. If a patient needs a blood at a clinic, blood donors in vicinity can be contacted through using a clinic management service provided in this application. Registered donors will get notification for the blood requests only if their blood group is compatible with the requested blood type and in the same city/region. Then matching blood donors can go to the requesting clinic and donate. BLOODR application provides a reliable platform to connect local blood donors with patients. BLOODR creates a communication channel through authenticated clinics whenever a patient needs blood donation. It is a useful tool to find compatible blood donors who can receive blood request posts in their local area. Clinics can use this web application to maintain the blood donation activity. Future improvement of the BLOODR is explained.

  16. A novel point mutation (G[sup [minus]1] to T) in a 5[prime] splice donor site of intron 13 of the dystrophin gene results in exon skipping and is responsible for Becker Muscular Dystrophy

    The mutations in one-third of Duchenne and Becker muscular dystrophy patients remain unknown, as they do not involve gross rearrangements of the dystrophin gene. The authors now report a defect in the splicing of precursor mRNA (pre-mRNA), resulting from a maternally inherited mutation of the dystrophin gene in a patient with Becker muscular dystrophy. This defect results from a G-to-T transversion at the terminal nucleotide of exon 13, within the 5[prime] splice site of intron 13, and causes complete skipping of exon 13 during processing of dystrophin pre-mRNA. The predicted polypeptide encoded by the aberrant mRNA is a truncated dystrophin lacking 40 amino acids from the amino-proximal end of the rod domain. This is the first report of an intraexon point mutation that completely inactivates a 5[prime] splice donor site in dystrophin pre-mRNA. Analysis of the genomic context of the G[sup [minus]1]-to-T mutation at the 5[prime] splice site supports the exon-definition model of pre-mRNA splicing and contributes to the understanding of splice-site selection. 48 refs., 5 figs.

    There are no published series of the assessment process, profiles and outcomes of anonymous, directed or nondirected live liver donation. The outcomes of 29 consecutive potential anonymous liver donors at our center were assessed. We used our standard live liver assessment process, augmented with the following additional acceptance criteria: a logical rationale for donation, a history of social altruism, strong social supports and a willingness to maintain confidentiality of patient information. Seventeen potential donors were rejected and 12 donors were ultimately accepted (six male, six female). All donors were strongly motivated by a desire and sense of responsibility to help others. Four donations were directed toward recipients who undertook media appeals. The donor operations included five left lateral segmentectomies and seven right hepatectomies. The overall donor morbidity was 40% with one patient having a transient Clavien level 3 complication (a pneumothorax). All donors are currently well. None expressed regret about their decision to donate, and all volunteered the opinion that donation had improved their lives. The standard live liver donor assessment process plus our additional requirements appears to provide a robust assessment process for the selection of anonymous live liver donors. Acceptance of anonymous donors enlarges the donor liver pool. © 2010 The Authors Journal compilation © 2010 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Understanding host-guest interactions is one of the key requirements for adjusting properties in metal-organic frameworks (MOFs). In particular, systems with coordinatively unsaturated Lewis acidic metal sites feature highly selective adsorption processes. This is attributed to strong interactions with Lewis basic guest molecules. Here we show that a combination of 13 C MAS NMR spectroscopy with state-of-the-art density functional theory (DFT) calculations allows one to unravel the interactions of water, 2-aminopyridine, 3-aminopyridine, and diethylamine with the open metal sites in Cr-MIL-101. The 13 C MAS NMR spectra, obtained with ultrafast magic-angle spinning, are well resolved, with resonances distributed over 1000 ppm. They present a clear signature for each guest at the open metal sites. Based on competition experiments this leads to the following binding preference: water open metal sites, the NMR data offer additional information about the guest and framework dynamics. We expect that our strategy has the potential for probing the binding situation of adsorbate mixtures at the open metal sites of MOFs in general and thus accesses the microscopic interaction mechanisms for this important material class, which is essential for deriving structure-property relationships.

  20. Increasing the supply of kidneys for transplantation by making living donors the preferred source of donor kidneys.

    2014-12-01

    At the present time, increasing the use of living donors offers the best solution to the organ shortage problem. The clinical questions raised when the first living donor kidney transplant was performed, involving donor risk, informed consent, donor protection, and organ quality, have been largely answered. We strongly encourage a wider utilization of living donation and recommend that living donation, rather than deceased donation, become the first choice for kidney transplantation. We believe that it is ethically sound to have living kidney donation as the primary source for organs when the mortality and morbidity risks to the donor are known and kept extremely low, when the donor is properly informed and protected from coercion, and when accepted national and local guidelines for living donation are followed.

    Full Text Available Of the various options for patients with end stage renal disease, kidney transplantation is the treatment of choice for a suitable patient. The kidney for transplantation is retrieved from either a cadaver or a live donor. Living donor nephrectomy has been developed as a method to address the shortfall in cadaveric kidneys available for transplantation. Laparoscopic living donor nephrectomy (LLDN, by reducing postoperative pain, shortening convalescence, and improving the cosmetic outcome of the donor nephrectomy, has shown the potential to increase the number of living kidney donations further by removing some of the disincentives inherent to donation itself. The technique of LLDN has undergone evolution at different transplant centers and many modifications have been done to improve donor safety and recipient outcome. Virtually all donors eligible for an open surgical procedure may also undergo the laparoscopic operation. Various earlier contraindications to LDN, such as right donor kidney, multiple vessels, anomalous vasculature and obesity have been overcome with increasing experience. Laparoscopic live donor nephrectomy can be done transperitoneally or retroperitoneally on either side. The approach is most commonly transperitoneal, which allows adequate working space and easy dissection. A review of literature and our experience with regards to standard approach and the modifications is presented including a cost saving model for the developing countries. An assessment has been made, of the impact of LDN on the outcome of donor and the recipient.

  4. Accumulation of GC donor splice signals in mammals

    2008-07-01

    Full Text Available Abstract The GT dinucleotide in the first two intron positions is the most conserved element of the U2 donor splice signals. However, in a small fraction of donor sites, GT is replaced by GC. A substantial enrichment of GC in donor sites of alternatively spliced genes has been observed previously in human, nematode and Arabidopsis, suggesting that GC signals are important for regulation of alternative splicing. We used parsimony analysis to reconstruct evolution of donor splice sites and inferred 298 GT > GC conversion events compared to 40 GC > GT conversion events in primate and rodent genomes. Thus, there was substantive accumulation of GC donor splice sites during the evolution of mammals. Accumulation of GC sites might have been driven by selection for alternative splicing.

    Full Text Available Background. Every effort should be made to optimize surgical techniques and to minimize potential morbidity rates associated with live donor operations. Advances in a minimally invasive approach by robotic surgery to donor nephrectomy have raised the possibility of applying this technique to live donor bowel resections for intestinal transplantation. Methods. We report the first 5 consecutive cases of a robotic-assisted live donor ileal segmentectomy. We describe the technical aspects of the procedure, discuss the rationale for considering this option, and evaluate potential advantages of this approach. Results. We found that this new approach is associated with less postoperative discomfort, a shorter hospital length of stay, and a faster recovery of bowel function compared to our previous open surgery. Conclusions. Our initial experience suggests that robotic surgery is a safe and feasible procedure for live donor ileal resection for intestinal transplantation and is a useful alternative to conventional open surgery.

  11. Marginal kidney donor

    2007-01-01

    Full Text Available Renal transplantation is the treatment of choice for a medically eligible patient with end stage renal disease. The number of renal transplants has increased rapidly over the last two decades. However, the demand for organs has increased even more. This disparity between the availability of organs and waitlisted patients for transplants has forced many transplant centers across the world to use marginal kidneys and donors. We performed a Medline search to establish the current status of marginal kidney donors in the world. Transplant programs using marginal deceased renal grafts is well established. The focus is now on efforts to improve their results. Utilization of non-heart-beating donors is still in a plateau phase and comprises a minor percentage of deceased donations. The main concern is primary non-function of the renal graft apart from legal and ethical issues. Transplants with living donors outnumbered cadaveric transplants at many centers in the last decade. There has been an increased use of marginal living kidney donors with some acceptable medical risks. Our primary concern is the safety of the living donor. There is not enough scientific data available to quantify the risks involved for such donation. The definition of marginal living donor is still not clear and there are no uniform recommendations. The decision must be tailored to each donor who in turn should be actively involved at all levels of the decision-making process. In the current circumstances, our responsibility is very crucial in making decisions for either accepting or rejecting a marginal living donor.

  12. On the effect of nuclear bridge modes on donor-acceptor electronic coupling in donor-bridge-acceptor molecules

    Davis, Daly; Toroker, Maytal Caspary; Speiser, Shammai; Peskin, Uri

    2009-01-01

    We report a theoretical study of intra-molecular electronic coupling in a symmetric DBA (donor-bridge-acceptor) complex, in which a donor electronic site is coupled to an acceptor site by way of intervening orbitals of a molecular bridge unit. In the off-resonant (deep tunneling) regime of electronic transport, the lowest unoccupied molecular orbitals (MO's) of the DBA system are split into distinguishable donor/acceptor and bridge orbitals. The effect of geometrical changes at the bridge on the donor/acceptor electronic energy manifold is studied for local stretching and bending modes. It is demonstrated that the energy splitting in the manifold of donor/acceptor unoccupied MOs changes in response to such changes, as assumed in simple McConnell-type models. Limitations of the simple models are revealed where the electronic charging of the bridge orbitals correlates with increasing donor/acceptor orbital energy splitting only for stretching but not for bending bridge modes.

  13. Estimation of morbidity effects

    International Nuclear Information System (INIS)

    Ostro, B.

    1994-01-01

    Many researchers have related exposure to ambient air pollution to respiratory morbidity. To be included in this review and analysis, however, several criteria had to be met. First, a careful study design and a methodology that generated quantitative dose-response estimates were required. Therefore, there was a focus on time-series regression analyses relating daily incidence of morbidity to air pollution in a single city or metropolitan area. Studies that used weekly or monthly average concentrations or that involved particulate measurements in poorly characterized metropolitan areas (e.g., one monitor representing a large region) were not included in this review. Second, studies that minimized confounding ad omitted variables were included. For example, research that compared two cities or regions and characterized them as 'high' and 'low' pollution area were not included because of potential confounding by other factors in the respective areas. Third, concern for the effects of seasonality and weather had to be demonstrated. This could be accomplished by either stratifying and analyzing the data by season, by examining the independent effects of temperature and humidity, and/or by correcting the model for possible autocorrelation. A fourth criterion for study inclusion was that the study had to include a reasonably complete analysis of the data. Such analysis would include an careful exploration of the primary hypothesis as well as possible examination of te robustness and sensitivity of the results to alternative functional forms, specifications, and influential data points. When studies reported the results of these alternative analyses, the quantitative estimates that were judged as most representative of the overall findings were those that were summarized in this paper. Finally, for inclusion in the review of particulate matter, the study had to provide a measure of particle concentration that could be converted into PM10, particulate matter below 10

    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.

    For 21 putative BRCA1 and BRCA2 splice site variants, the concordance between mRNA analysis and predictions by in silico programs was evaluated. Aberrant splicing was confirmed for 12 alterations. In silico prediction tools were helpful to determine for which variants cDNA analysis is warranted, however, predictions for variants in the Cartegni consensus region but outside the canonical sites, were less reliable. Learning algorithms like Adaboost and Random Forest outperformed the classical tools. Further validations are warranted prior to implementation of these novel tools in clinical settings. Additionally, we report here for the first time activated cryptic donor sites in the large exon 11 of BRCA2 by evaluating the effect at the cDNA level of a novel tandem duplication (5' breakpoint in intron 4; 3' breakpoint in exon 11) and of a variant disrupting the splice donor site of exon 11 (c.6841+1G > C). Additional sites were predicted, but not activated. These sites warrant further research to increase our knowledge on cis and trans acting factors involved in the conservation of correct transcription of this large exon. This may contribute to adequate design of ASOs (antisense oligonucleotides), an emerging therapy to render cancer cells sensitive to PARP inhibitor and platinum therapies. © 2017 Wiley Periodicals, Inc.

    Full Text Available Infections remain a major cause of morbidity and mortality in transplant patients. Organ recipients are also susceptible to donor-derived pathogens and the majority of donor infections are easily treatable. Rarely, some pathogens have produced life-threatening complications by compromising the vascular anastomosis. In this case series we report loss of two kidney allografts secondary to vascular complications due to Candida albicans. Both recipients received grafts from a common donor, in whom Candida bacteremia in the donor was not apparent at the time of organ acceptance but became apparent on delayed cultures.

    The transplantation of organs and tissues from one human to another human has become an essential and well established form of therapy for many types of organ and tissue failure. In Malaysia, kidney, cornea and bone marrow transplantation are well established. Recently, liver, bone and heart transplanation have been performed. Unfortunately, because of the lack of cadaveric organ donation, only a limited number of solid organ transplantation have been performed. The cadaveric organ donor rate in Malaysia is low at less than one per million population. The first tissue transplanted in Malaysia was the cornea which was performed in the early 1970s. At that time and even now the majority of corneas came from Sri Lanka. The first kidney transplant was performed in 1975 from a live related donor. The majority of the 629 kidney transplants done at Hospital Kuala Lumpur to date have been from live related donors. Only 35 were from cadaver donors. Similarly, the liver transplantation programme which started in 1995 are from live related donors. A more concerted effort has been made recently to increase the awareness of the public and the health professionals on organ and tissue donation. This national effort to promote organ and tissue donation seems to have gathered momentum in 1997 with the first heart transplant successfully performed at the National Heart Institute. The rate of cadaveric donors has also increased from a previous average of I to 2 per year to 6 per year in the last one year. These developments are most encouraging and may signal the coming of age of our transplantati on programme. The Ministry of Health in conjunction with various institutions, organizations and professional groups, have taken a number of proactive measures to facilitate the development of the cadaveric organ donation programme. Efforts to increase public awareness and to overcome the negative cultural attitude towards organ donation have been intensified. Equally important are efforts

    In the present phase of epidemiological transition, the most frequent causes of youth morbidity are disorders in reproductive health, mental disorders and injuries which are not life threatening. This, so-called new youth morbidity, is most often caused by their risky behavior, which in the field of sexuality often leads to unplanned pregnancies and abortions, as well as sexually transmitted infections. Misuse of tobacco, alcohol and narcotics, which is most commonly started in adolescence, h...

    Donor safety is the major concern in living donor liver transplantation, although hepatic resection may be associated with postoperative coagulopathy. Recently, the use of sugammadex has been gradually increased, but sugammadex is known to prolong prothrombin time (PT) and activated partial thromboplastin time (aPTT). We compared the postoperative coagulation profiles and outcomes of sugammadex versus pyridostigmine group in donors receiving living donor hepatectomy.Consecutive donor hepatectomy performed between September 2013 and August 2016 was retrospectively analyzed. For reversal of rocuronium-induced neuromuscular blockade, donors received sugammadex 4 mg/kg or pyridostigmine 0.25 mg/kg. The primary end-points were laboratory findings (PT, aPTT, hemoglobin, platelet count) and clinically evaluated postoperative bleeding (relaparotomy for bleeding, cumulative volume collected in drains). Secondary outcomes were anesthesia time, postoperative hospital day.Of 992 donors, 383 treated with sugammadex and 609 treated with pyridostigmine for the reversal of neuromuscular blockade. There were no significant differences between both groups for drop in hemoglobin and platelet, prolongation in PT, aPTT, and the amount of 24-h drain volume. Bleeding events within 24 h were reported in 2 (0.3%) for pyridostigmine group and 0 (0%) for sugammadex group (P = .262). Anesthesia time was significantly longer in pyridostigmine group than that in sugammadex group (438.8 ± 71.4 vs. 421.3 ± 62.3, P sugammadex group (P = .002).Sugammadex 4 mg/kg was not associated with increased bleeding tendency, but associated with reduced anesthesia time and hospital stay. Therefore, sugammadex may be safely used and will decrease morbidity in donor undergoing living-donor hepatectomy.

    Living donor segmental pancreas transplants (LDSPTx) have been performed selectively to offer a preemptive transplant option for simultaneous pancreas-kidney recipients and to perform a single operation decreasing the cost of pancreas after kidney transplant. For solitary pancreas transplants, this option historically provided a better immunologic match. Although short-term donor outcomes have been documented, there are no long-term studies. We studied postdonation outcomes in 46 segmental pancreas living donors. Surgical complications, risk factors (RF) for development of diabetes mellitus (DM) and quality of life were studied. A risk stratification model (RSM) for DM was created using predonation and postdonation RFs. Recipient outcomes were analyzed. Between January 1, 1994 and May 1, 2013, 46 LDSPTx were performed. Intraoperatively, 5 (11%) donors received transfusion. Overall, 9 (20%) donors underwent splenectomy. Postoperative complications included: 6 (13%) peripancreatic fluid collections and 2 (4%) pancreatitis episodes. Postdonation, DM requiring oral hypoglycemics was diagnosed in 7 (15%) donors and insulin-dependent DM in 5 (11%) donors. RSM with three predonation RFs (oral glucose tolerance test, basal insulin, fasting plasma glucose) and 1 postdonation RF, greater than 15% increase in body mass index from preoperative (Δ body mass index >15), predicted 12 (100%) donors that developed postdonation DM. Quality of life was not significantly affected by donation. Mean graft survival was 9.5 (±4.4) years from donors without and 9.6 (±5.4) years from donors with postdonation DM. LDSPTx can be performed with good recipient outcomes. The donation is associated with donor morbidity including impaired glucose control. Donor morbidity can be minimized by using RSM and predonation counseling on life style modifications postdonation.

    Drowning, a common cause of death in the pediatric population, is a potentially large donor pool for OLT. Anecdotally, transplant centers have deemed these organs high risk over concerns for infection and graft dysfunction. We theorized drowned donor liver allografts do not portend worse outcomes and therefore should not be excluded from the donation pool. We reviewed our single-center experience of pediatric OLTs between 1988 and 2015 and identified 33 drowned donor recipients. These OLTs were matched 1:2 to head trauma donor OLTs from our center. A chart review assessed postoperative peak AST and ALT, incidence of HAT, graft and recipient survival. Recipient survival at one year between patients with drowned donor vs head trauma donor allografts was not statistically significant (94% vs 97%, P=.63). HAT incidence was 6.1% in the drowned donor group vs 7.6% in the control group (P=.78). Mean postoperative peak AST and ALT was 683 U/L and 450 U/L for drowned donors vs 1119 U/L and 828 U/L in the matched cohort. These results suggest drowned donor liver allografts do not portend worse outcomes in comparison with those procured from head trauma donors. © 2017 John Wiley & Sons A/S.

    Written and video approaches to donor education have been shown to enhance donation attitudes and intentions to give blood, particularly when the information provides specific coping suggestions for donation-related concerns. This study extends this work by comparing Web-based approaches to donor preparation among donors and nondonors. Young adults (62% female; mean [±SD] age, 19.3 [±1.5] years; mean [range] number of prior blood donations, 1.1 [0-26]; 60% nondonors) were randomly assigned to view 1) a study Web site designed to address common blood donor concerns and suggest specific coping strategies (n = 238), 2) a standard blood center Web site (n = 233), or 3) a control Web site where participants viewed videos of their choice (n = 202). Measures of donation attitude, anxiety, confidence, intention, anticipated regret, and moral norm were completed before and after the intervention. Among nondonors, the study Web site produced greater changes in donation attitude, confidence, intention, and anticipated regret relative to both the standard and the control Web sites, but only differed significantly from the control Web site for moral norm and anxiety. Among donors, the study Web site produced greater changes in donation confidence and anticipated regret relative to both the standard and the control Web sites, but only differed significantly from the control Web site for donation attitude, anxiety, intention, and moral norm. Web-based donor preparation materials may provide a cost-effective way to enhance donation intentions and encourage donation behavior. © 2012 American Association of Blood Banks.

  15. Iron deficiency in blood donors

    Directory of Open Access Journals (Sweden)

    Rodolfo Delfini Cançado

    Full Text Available CONTEXT: Blood donation results in a substantial loss of iron (200 to 250 mg at each bleeding procedure (425 to 475 ml and subsequent mobilization of iron from body stores. Recent reports have shown that body iron reserves generally are small and iron depletion is more frequent in blood donors than in non-donors. OBJECTIVE: The aim of this study was to evaluate the frequency of iron deficiency in blood donors and to establish the frequency of iron deficiency in blood donors according to sex, whether they were first-time or multi-time donors, and the frequency of donations per year. DESIGN: From September 20 to October 5, 1999, three hundred blood donors from Santa Casa Hemocenter of São Paulo were studied. DIAGNOSTIC TESTS: Using a combination of biochemical measurements of iron status: serum iron, total iron-binding capacity, transferrin saturation index, serum ferritin and the erythrocyte indices. RESULTS: The frequency of iron deficiency in blood donors was 11.0%, of whom 5.5% (13/237 were male and 31.7% (20/63 female donors. The frequency of iron deficiency was higher in multi-time blood donors than in first-time blood donors, for male blood donors (7.6% versus 0.0%, P < 0.05 and female ones (41.5% versus 18.5%, P < 0.05. The frequency of iron deficiency found was higher among the male blood donors with three or more donations per year (P < 0.05 and among the female blood donors with two or more donations per year (P < 0.05. CONCLUSIONS: We conclude that blood donation is a very important factor for iron deficiency in blood donors, particularly in multi-time donors and especially in female donors. The high frequency of blood donors with iron deficiency found in this study suggests a need for a more accurate laboratory trial, as hemoglobin or hematocrit measurement alone is not sufficient for detecting and excluding blood donors with iron deficiency without anemia.

    2011-08-01

    Full Text Available Abstract Background While influenza vaccination results in protective antibodies against primary infections, clearance of infection is primarily mediated through CD8+ T cells. Studying the CD8+ T cell response to influenza epitopes is crucial in understanding the disease associated morbidity and mortality especially in at risk populations such as the elderly. We compared the CD8+ T cell response to immunodominant and subdominant influenza epitopes in HLA-A2+ control, adult donors, aged 21-42, and in geriatric donors, aged 65 and older. Results We used a novel artificial Antigen Presenting Cell (aAPC based stimulation assay to reveal responses that could not be detected by enzyme-linked immunosorbent spot (ELISpot. 14 younger control donors and 12 geriatric donors were enrolled in this study. The mean number of influenza-specific subdominant epitopes per control donor detected by ELISpot was only 1.4 while the mean detected by aAPC assay was 3.3 (p = 0.0096. Using the aAPC assay, 92% of the control donors responded to at least one subdominant epitopes, while 71% of control donors responded to more than one subdominant influenza-specific response. 66% of geriatric donors lacked a subdominant influenza-specific response and 33% of geriatric donors responded to only 1 subdominant epitope. The difference in subdominant response between age groups is statistically significant (p = 0.0003. Conclusion Geriatric donors lacked the broad, multi-specific response to subdominant epitopes seen in the control donors. Thus, we conclude that aging leads to a decrease in the subdominant influenza-specific CTL responses which may contribute to the increased morbidity and mortality in older individuals.

    Full Text Available Background: Women in the perimenopausal period are reported to be vulnerable to psychiatric disorders. Aim: To assess the psychiatric morbidity in perimenopausal women aged 45–55 years. Materials and Methods: This cross-sectional, observational, hospital-based study was conducted at the Department of Psychiatry in a tertiary care hospital attached to a medical college. The study sample consisted of consecutive women in perimenopause as diagnosed by a gynecologist and written informed consent for inclusion in the study. Women with a previous history of psychiatric illnesses, with a major medical illness, or who had undergone surgical menopause were excluded from the study. All women were evaluated with a brief questionnaire for collecting demographic and clinical information and the Mini International Neuropsychiatric Interview for assessing psychiatric disorders. Results: Of the 108 women in perimenopause included in the study, 31% had depressive disorder, 7% had anxiety, while 5% had depressive disorder with anxiety features. Psychiatric morbidity was significantly more in women having lesser education, from rural background, with a history of psychiatric illness in the family, a later age of menarche, and in the late stage of perimenopause. Conclusions: Women in the perimenopause affected by psychiatric morbidity were most commonly diagnosed with depression. As perimenopause is a time of vulnerability in women, attention to signs and symptoms of depression may be required so that they may lead a more productive life.

    Donor vigilance is an important part of the quality management system of blood transfusion services. The evaluation of donor side effects helps to improve the donation process and donor compliance. The aim of the present study was to evaluate donor vigilance data in whole blood and plasmapheresis donors of a blood donor service. Donors fulfilling current national and European eligibility criteria underwent whole blood and plasmapheresis donation (PCS and MCS+ (Haemonetics, Braintree, USA), A 200 (Fenwal, Round Lake, USA). Whole blood was collected at fixed and mobile sites while plasmaphereses were performed at 8 plasma centers. From 2011 to 2013 donor information was provided for gender, age, body weight, height, first and repeat donation. Donors were monitored for venipuncture and circulatory associated side effects. The total incidences of adverse events were 5004 (0.56%) in repeat donors and 2111 (2.78%) in first time donors for whole blood donation and 3323 (1.01%) and 514 (7.96%) for plasmaphereses, respectively. Circulatory associated events were 2679 (0.30%) for whole blood donation and 1624 (0.49%) for plasmaphereses. Our donor vigilance data of a blood transfusion service show that whole blood and plasmapheresis are safe with low incidences of adverse events. Repeat donation and age are predictors for low rates of adverse events. On the other hand, first time donation and female gender were associated with higher incidences of adverse events.

    Phosphorus shallow donors having the symmetry lower than T d are studied by pulsed EPR. In diamond:P and 3C-SiC:P, the symmetry is lowered to D 2d and the density of the donor wave function on the phosphorus atom exhibits a predominant p-character. In 4H-SiC:P with the site symmetry of C 3v , the A 1 ground state of the phosphorus donors substituting at the quasi-cubic site of silicon shows an axial character of the distribution of the donor wave function in the vicinity of the phosphorus atom

    Donor based spin qubits are a promising platform for quantum computing. Single qubits using timed implant of donors have been demonstrated.1 Extending this to multiple qubits requires precise control over the placement and number of donors. Such control can be achieved by using a combination of low-energy heavy-ion implants (to reduce depth straggle), electron-beam lithography (to define position), focused ion beam (to localize implants to one lithographic site) and counting the number of implants with a single ion detector.2 We report transport measurements on MOS quantum dots implanted with 5, 10 and 20 Sb donors using the approach described above. A donor charge transition is identified by a charge offset in the transport characteristics. Correlation between the number of donors and the charge offsets is studied. These results are necessary first steps towards fabricating donor nanostructures for two qubit interactions. This work was performed, in part, at the Center for Integrated Nanotechnologies, a U.S. DOE Office of Basic Energy Sciences user facility. The work was supported by Sandia National Laboratories Directed Research and Development Program.

    Donor selection is one of the most important aspects of tissue banking practice. Without a good donor selection criteria, the results of any effort of trying to preserve tissues will have disastrous outcome for the recipient of these tissues. While with a very good and strict donor selection the Tissue Bank can guarantee safe and effective tissue allografts. There are significant aspects in the history and physical examination of the donor that must be emphasized. A donor exclusion criteria has also been formulated together with a list of all the needed laboratory examinations to eliminate possible diseases that may be transferred from the donor. The methods of procurement of tissue allografts from living and cadaver donors will be described. The limitations and advantages of each will be taken.There are also special restrictions that are important in the practice of removing the tissues from the donors. All the necessary equipment should be ready and the potential risk on the personnel should be known to all doing Tissue Banking

    Full Text Available In the current situation of the shortage of suitable donor organs, heart transplantation from older donors is one of the ways to increase the performance of more heart transplants, particularly, in patients with urgent need of transplantation. While planning a heart transplantation from older donor one should consider increased risk of early cardiac allograft dysfunction, preexisting coronary artery disease, accelerated transplant vasculopathy which may adversely affect early and long-term survival of recipients. Subject to careful selection of donor–recipient pairs, effective prevention and treatment of early cardiac allograft dysfunction, pre-existing atherosclerosis and transplant vasculopathy the early and long-term survival of heart transplant recipients from older donors is comparable to heart transplantation from young donors.

    The authors have attempted to measure morbidity involved in mortality, from French regional statistics of causes of death, for the 1968-1970 period. Particularly, they have estimated prevalence rates (proportion of patients at a given moment) and incidence rates (annual proportion of new patients). These rates have been assessed by sex, and for age groups: 15-44 years, 45-64 years, 65-74 years, 75 years and more, and for 18 leading causes of death, according to the International Classification of Diseases (1965). Statistics of causes of deaths have been corrected to take into account non specified causes of death.

    Full Text Available BACKGROUND: Blood transfusion is an essential element of a health care system. Safety of blood transfusion is of extreme importance in order to avoid any severe morbidity and mortality in the patient. By screening donated blood units, we get a clue of the prevalence of those infections among donor pop ulations and consequently the safety of collected donations. It also gives us an idea of the prevalence of the Transfusion transmissible infections ( TTIs in the community. OBJECTIVES : To find out the sero - prevalence of TTIs namely HBV (Hepatitis B in the blood donor population at MMC&RI, Mysore. To stratify sero prevalence of TTIs based on the age and sex of the donor population . METHODOLOGY: The present study was carried out in the Blood Bank , Mysore Medical College and Research Institute , Mysore during the period from November 2012 to May 2014 among 14075 blood donors. All the samples were screened for hepatitis B surface antigen (HBsAg by ELISA method . RESULTS : Out of a total of 14075 blood donors , a total of 103 tested positive for TTIs . 94.08% were males and remaining 5.92% were females. A majority of donors were voluntary donors (85.79% and a majority of the donors were between the age group of 18 - 39 years (78.17%. The prevalence rate of HBV in blood donors was 0.73%. The seroprevale nce in voluntary donors was 0.57% and in replacement donors was 1.75 % respectively. CONCLUSION : Voluntary blood donation is safe, compared to replacement as high prevalence of Hepatitis B is observed in replacement donors.

  14. The benefits of reduced morbidity

    1994-07-01

    Morbidity benefits refer to increases in utility arising from reductions in incidents of acute health impairments and from increases in the probability of developing chronic diseases. The impairments would run the gamut from a cough-day to a bed-disability-day, while the chronic diseases include classic pollution-related diseases, such as cancer, to in utero effects and learning disabilities. As with mortality benefits, there could be benefits to oneself and family and friends as well as benefits based on altruism. A major difference between the mortality and morbidity valuation literatures is that while estimates of the former are always based on risk (one is never trying to obtain values for avoiding certain death), estimates of the latter generally are not. That is, most of the theory and empirical estimates are based on models where the effect to be avoided is certain. This assumption holds reasonably well for estimating common acute effects, for example, the willingness to pay (WTP) for one less cough-day. It works less well, if at all, for chronic illness endpoints, where benefits seem to be appropriately expressed in terms of reduced risk of developing a disease or impairment.

  16. Jealous love and morbid jealousy.

    Maggini, Carlo; Lundgren, Eva; Leuci, Emanuela

    2006-12-01

    Jealous love and morbid jealousy, although inextricably linked, cannot be considered the same: jealous love (trait jealousy) is the behavioral and cognitive-affective precondition of morbid jealousy (state jealousy). Love is jealous when it is devoured by the desire for the exclusive and total possession of the partner, whose unconditional and continued presence is avidly requested. This type of love, in addition, is permeated by the need to know what the other is thinking, in order to scrutinize every minimal flaw in the faithfulness of the partner even in his or her innermost thoughts and fantasies; in it, jealousy is virtually always present, even in the absence of a triggering event, because captative love, by its very nature, includes the expectation of a conflict which inevitably actually takes place in reality. Finally, jealousy emerges as an emotional event (jealous flash) in response to a more or less significant change in the behavior of the partner, and reveals to the jealous individual a dimension which was previously latent or inexistent. This intense and brief experience, leaves a more or less blurred memory behind, and tends to progressively repeat itself and take root as a feeling.

    2017-09-01

    The shortage of suitable organs is the biggest obstacle for transplants. At present, most organs for transplant in the United States are from donation after neurologic determination of death (brain death). Potential organs for transplant need to maintain their viability during a series of insults, including the original disease, physiologic derangements during the dying process, ischemia, and reperfusion. Proper donor management before, during, and after procurement has potential to increase the number and quality of organs from donors. Anesthesiologists need to understand the physiologic derangements associated with brain death and the updated donor management during the periprocurement period. Copyright © 2017 Elsevier Inc.

    The electrophysical properties of the n-type conductivity germanium, irradiated through protons, is studied by the volt-farad method. It is shown that the heat treatment of the implanted germanium at the temperature of 200-300 deg C leads to formation of the fast-diffusing second-rate donors. It is established that the diffusion coefficient of the identified donors coincides with the diffusion coefficient of the atomic hydrogen with an account of the capture on the traps. The conclusion is made, that the atomic hydrogen is the second-rate donor center in germanium [ru

    Full Text Available OBJECTIVES: As the advancements, modifications and standardization of laparoscopy are taking place, there is a need for the reduction in morbidity associated with laparoscopic live donor nephrectomy. This study was performed to determine and reconfirm the advantages of laparoscopic donor nephrectomy over its open counterpart. MATERIALS AND METHODS: Two hundred open live donor nephrectomy (ODN cases were compared to 264 cases of laparoscopic live donor nephrectomy (LDN. Pretransplant functional and radiological evaluation was done routinely by excretory urogram and renal arteriography. In case of vascular variations, CT angiography was preferred. Open cases were done by conventional method and laparoscopic group underwent certain technical and surgical modifications, including meticulous planning for the port placement. Operative time, analgesia requirement, start of the orals, hospital stay, blood loss, late allograft function, incidence of rejection, complications and technical problems were analyzed. RESULTS: Operative time was 135.8 ± 43 and 165 ± 44.4 min ( P < 0.0001, requirement of analgesia was 60.5 ± 40 and 320 ± 120 mg ( P < 0.0001, hospital stay was 4 ± 0.04 and 5.7 ± 2.03 days ( P < 0.0001, warm ischemia time was 6.1 ± 2.0 and 4.1 ± 0.80 min ( P < 0.0001 and time taken for the serum creatinine to stabilize in the recipient was 4.1 ± 1.6 and 4.32 ± 1.40 days ( P =0.06 for LDN and ODN groups respectively. There was a significant reduction in the blood loss in LDN group ( P =0.0005. Overall complications were 6.81 and 14.5% and ureteric injury was seen in 0.37 and 1% in LDN and ODN respectively. CONCLUSION: Laparoscopic live donor nephrectomy can now be performed with low morbidity and mortality to both donors and recipients and is proving to be the preferred operation to open donor nephrectomy. Our continued innovations in technical modifications have made this novel operation successful.

    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). Graft survival within five years based on points (any combination) was 77.2% (0-4), 69.1% (5-8) and 57.9% (>8). In recipients with >8 points, graft survival was 42% (model for end-stage liver disease [MELD] score recipients receiving grafts from donors with a donor risk index >1.7. In center-specific data within the first year, subjects with ≥5 points (vs. 0-4) had longer hospitalization (11 vs. 8 days, p need to be reassessed. The proposed clinical tool may be helpful for center-specific assessment of risk of graft failure in non-HCV patients and for discussion regarding relevant morbidity in selected subsets. Over the last decade, liver transplantation of sicker, older patient with multiple co-morbidities has increased. In this study, we show that a set of recipient factors (recipient age >60 years, ventilator status, diabetes, hemodialysis and creatinine >1.5 mg/dl) can help identify patients that may not do well after transplant.

However, the nutritional needs for appropriate growth and neurodevelopmental outcomes of such a particular population of infants should be attentively evaluated, considering also the indication to an appropriate fortification of human milk. The target is to achieve growth potential for preterm newborns while ensuring good metabolic outcomes and normal neurological development. When mother's milk is unavailable or in short supply, donor human milk (DHM represents the second best choice and, although somewhat modified by the Holder pasteurization process, it preserves many benefits when compared to formula, as documented by more and more reports, randomized controlled trials, and meta-analyses published in the past few years. Evidence exists of the protection exerted by DHM from necrotizing enterocolitis, while further studies are required to look at possible beneficial effects regarding infections, bronchopulmonary dysplasia, long-term cardiovascular risk factors, feeding tolerance, neurological outcome, and allergy. Finally, the concern that the use of DHM might decrease preterm infant breastfeeding is being raised. Conversely, publications exist showing that the use of DHM in the neonatal unit increases breastfeeding rates at discharge for infants of very low birth weight.

    Extremes in body weight are a relative contraindication to cardiac transplantation. We retrospectively reviewed 474 consecutive adult patients (377 male, 97 female, mean age 50.3+/-12.2 years), who received 444 primary and 30 heart retransplants between January of 1992 and January of 1999. Of these, 68 cachectic (body mass index [BMI]27-30 kg/m2), and 55 morbidly obese (BMI>30 kg/m2) patients were compared with 238 normal-weight recipients (BMI=20-27 kg/m2). We evaluated the influence of pretransplant BMI on morbidity and mortality after cardiac transplantation. Kaplan-Meier survival distribution and Cox proportional hazards model were used for statistical analyses. Morbidly obese as well as cachectic recipients demonstrated nearly twice the 5-year mortality of normal-weight or overweight recipients (53% vs. 27%, respectively, P=0.001). An increase in mortality was seen at 30 days for morbidly obese and cachectic recipients (12.7% and 17.7%, respectively) versus a 30-day mortality rate of 7.6% in normal-weight recipients. Morbidly obese recipients experienced a shorter time to high-grade acute rejection (P=0.004) as well as an increased annual high-grade rejection frequency when compared with normal-weight recipients (P=0.001). By multivariable analysis, the incidence of transplant-related coronary artery disease (TCAD) was not increased in morbidly obese patients but cachectic patients had a significantly lower incidence of TCAD (P=0.05). Cachectic patients receiving oversized donor hearts had a significantly higher postoperative mortality (P=0.02). The risks of cardiac transplantation are increased in both morbidly obese and cachectic patients compared with normal-weight recipients. However, the results of cardiac transplantation in overweight patients is comparable to that in normal-weight patients. Recipient size should be kept in mind while selecting patients and the use of oversized donors in cachectic recipients should be avoided.

    International travel, particularly to developing countries, is becoming increasingly common among the Israeli population, including an increase in the number of travelling children. Since children are a distinct travellers' population, data about their post-travel morbidity are needed. A retrospective study which examined all children (0-19 years old) who presented to our centre after international travel from 1999 to 2015. About 314 children were seen. The mean age was 10 years (SD ± 5.8). Most of the patients (80.6%) were tourists, and the rest were expatriates. The main destinations visited were South-Asia (46.5%), Sub-Saharan Africa (33.4%), Latin-America (7%) and Europe (6.4%). Overall, the most common diagnoses were gastrointestinal (GI) (mainly chronic) disorders (30.6%), followed by febrile diseases (26.4%), among which 18.1% of patients were diagnosed with dengue fever and 12% with malaria. Dermatologic conditions accounted for 25.2%. Additional diagnoses were schistosomiasis (6.4%) and neuropsychiatric symptoms (2.2%). A substantial part, 10.8%, had eosinophilia, either symptomatic or asymptomatic. Travellers to Asia, compared to travellers to Africa, presented more commonly with GI illness (OR 2.02, 95% confidence interval 1.13-3.61), and dermatologic conditions (OR 1.94, 95% confidence interval 1.05-3.61). Morbidity was associated with a variety of transmission modes, such as food-borne illnesses (30.9%), bite and sting wounds (10.2%), mosquito-borne infections (8%), freshwater contact (6.7%) and tick-borne infections (2.2%). The main conditions seen in paediatric returning travellers were GI, febrile and dermatologic illnesses, some may be rare in their country of origin. Targeting care for the suspected pathogens based on updated knowledge of epidemiology and thorough travel history is essential. © International Society of Travel Medicine, 2017.

    Living related liver transplantation (LRLT) has been developed in response to the paediatric organ donor shortage. According to the International Living Donor Registry, 521 transplants had been performed in 515 patients between December 8 1988 and January 19 1996 in 30 centres worldwide. The overall actuarial patient and graft survival rates were 82.7 and 80%, respectively. Between June 17 1994 and November 30 1996, the authors performed 11 LRLT at the Chung Gung Memorial Hospital. The living donors consisted of 10 mothers and one father. The mean graft weight was 303 g and the mean graft recipient weight ratio was 2.2%. Donor hepatectomy was performed without vascular inflow occlusion. The intra-operative blood loss ranged from 30 mL to 120 mL with an average of 61 mL, and blood transfusion was not required in all donors both intra-operatively and during the postoperative period. Underlying diseases of the recipients were biliary atresia (n = 10) and glycogen storage disease (n = 1). The mean graft cold ischaemia time was 106 min, the mean second warm ischaemia time was 51 min and the mean interval between portal and arterial reperfusion was 81 min. The initial LRLT results were promising with all donors having been discharged without complication. The recipients experienced a few complications, all of which were manageable with early intervention. All 11 recipients are alive and well. These are encouraging results and the authors hope to expand the use of live donors for liver transplantation to cope with demand.

    Full Text Available Background: Studies assessing the prevalence of reproductive morbidity among males in India have chiefly focused on prevalence of Reproductive Tract Infections/Sexually Transmitted Infections (RTIs/STIs among males attending Sexually Transmitted Disease clinics, blood donors and other selected population groups, with only few focused on the magnitude and the type of reproductive morbidity amongst Indian males at community level. Objective: To estimate prevalence of reproductive morbidity including (RTIs/STIs among males in the age group of 20-50 years residing in an urban slum of Delhi. Methods: Out of 268 males in the targeted age group, selected by systematic random sampling, residing in an urban sum of Delhi, 260 males were subjected to clinical examination and laboratory investigations for diagnosis of reproductive morbidity. Laboratory investigations were done for diagnosis of Hepatitis B and C, Syphilis, Gonorrhoea, Non gonococcal urethritis and urinary tract infection. Results: A total of 90 (33.6% of 268 study subjects reported one or more perceived symptoms of reproductive tract / sexual morbidity in last six months. Overall reproductive morbidity based on clinical and laboratory diagnosis was present in 76 (29.2% study subjects and of this sexually acquired morbidity accounted for 21.2% cases. Hepatitis B was most common (10.3% reproductive morbidity followed by Urinary Tract Infection (5.0%, scabies (3.5% and congenital anomalies (3.5%. Conclusion: High prevalence of reproductive morbidity (29.2% amongst males in an urban slum highlights the need for more studies in different settings. There is a need for developing interventions in terms of early diagnosis and treatment and prevention.

    Morbid obesity, defined as a body mass index (BMI), i.e. weight (kg)/height (m2) over 36 for males and 38 for females, is a common condition and a threat for health, life and individual well being. Hitherto, surgery is the only effective treatment for weight reduction. Surgical methods can be malabsorptive, reducing the patients ability to absorb nutrients, or restrictive, reducing the capacity of food intake. Exclusively malabsorptive methods have been abandoned due to severe side effects. Restrictive methods, gastroplasties, reduces the compliance capacity of the stomach. Two types are performed laparoscopically, the vertical banded gastroplasty and the adjustable gastric banding. The proximal gastric by pass is also performed laparoscopically and is a combination of a restrictive proximal gastroplasty and a malabsorptive Roux-en-Y gastro-jejunal anastomosis. With laparoscopic adjustable gastric banding mean BMI was reduced from 41 kg/m2 to 33 kg/m2 (n = 43) after one year. Two years after surgery mean BMI was 30 kg/m2 (n = 16). The different operative techniques are further discussed in this paper.

  15. [Lack of donor organs as an argument for living donors?].

    In Germany more than 12,000 patients are presently waiting for an organ donation. Living donation makes sense for the long waiting time for a kidney, but it is not a permanent solution for the lack of organ donations. In the future topics which should be discussed are intensified public relations, a better family care and the allocation of rights and duties at the German coordinating agency. For all the prospects of success after a living donation the high standards of quality and security, which are targeted by the German donor organization in recipient protection, responsible evaluation of the expanded donor criteria and immunosuppressive therapy are all in favor of post-mortem organ donation. For all the phenomenal chance of success the priority of the post-mortem organ donation is regulated by law. The living donation remains an individual decision of the donor and the personal situation of life.

  16. Why Should Donors Care about Corruption?

    OpenAIRE

    Kolstad, Ivar

    2008-01-01

    Corruption is bad for donor business. Corruption reduces popular support for aid in donor countries. However, aid agencies should pay attention to corruption because it is the right thing to do, rather than just the smart thing to do. Donor anti-corruption policies require a strong grounding in ethics. Corruption produces bad development outcomes. This is the reasoning largely underlying donor anti-corruption efforts. The focus on consequences of corruption makes donor anticorruptioneffo...

    Full Text Available Background. While tobacco use by a renal transplant recipient has been shown to negatively affect graft and patient survival, the effect of smoking on the part of the kidney donor remains unknown. Methods. 29 smoking donors (SD and their recipients (SD-R as well as 71 non-smoking donors (ND and their recipients (ND-R were retrospectively reviewed. Preoperative demographics and perioperative variables including serum creatinine (Cr and glomerular filtration rate (GFR were calculated and stratified by amount of tobacco exposure in pack-years. Clinical outcomes were analyzed with a Student's t-test, chi-square, and multiple linear regression analysis (=0.05. Results. At most recent followup, SD-R's had a significantly smaller percent decrease in postoperative Cr than ND-R's (−57% versus −81%; =0.015 and lower calculated GFR's (37.0 versus 53.0 mL/min per 1.73 m2; <0.001. SD's had a larger percent increase in Cr than ND's at most recent followup (57% versus 40%; <0.001, with active smokers having a larger increase than those who quit, although this difference was not statistically significant (68% versus 52%; =0.055. Conclusions. Use of tobacco by kidney donors is associated with decreased posttransplant renal function, although smoking cessation can improve outcomes. Kidneys from donors who smoke should be used with caution.

  20. Dengue antibodies in blood donors.

    Ribas-Silva, Rejane Cristina; Eid, Andressa Ahmad

    2012-01-01

    Dengue is an urban arbovirus whose etiologic agent is a virus of the genus Flavorius with four distinct antigen serotypes (DENV-1, DENV-2, DENV-3 and DENV-4) that is transmitted to humans through the bite of the mosquito Aedes aegypti. The Campo Mourão region in Brazil is endemic for dengue fever. OBTECTIVE: The aim of this study was to evaluate the presence of IgG and IgM antibodies specific to the four serotypes of dengue in donors of the blood donor service in the city of Campo Mourão. Epidemiological records were evaluated and 4 mL of peripheral blood from 213 blood donors were collected in tubes without anticoagulant. Serum was then obtained and immunochromatographic tests were undertaken (Imuno-Rápido Dengue IgM/IgG(TM)). Individuals involved in the study answered a social and epidemiological questionnaire on data which included age, gender and diagnosis of dengue. Only three (1.4%) of the 213 blood tests were positive for IgG anti-dengue antibodies. No donors with IgM antibody, which identifies acute infection, were identified. The results of the current analysis show that the introduction of quantitative or molecular serological methods to determine the presence of anti-dengue antibodies or the detection of the dengue virus in blood donors in endemic regions should be established so that the quality of blood transfusions is guaranteed.

    X-linked Alport syndrome (XLAS) is a progressive hereditary nephropathy caused by mutations in the type IV collagen alpha chain 5 gene (COL4A5). Although many COL4A5 mutations have previously been identified, pathogenic synonymous mutations have not yet been described. A family with XLAS underwent mutational analyses of COL4A5 by PCR and direct sequencing, as well as transcript analysis of potential splice site mutations. In silico analysis was also conducted to predict the disruption of splicing factor binding sites. Immunohistochemistry (IHC) of kidney biopsies was used to detect α2 and α5 chain expression. We identified a hemizygous point mutation, c.876A>T, in exon 15 of COL4A5 in the proband and his brother, which is predicted to result in a synonymous amino acid change, p.(Gly292Gly). Transcript analysis showed that this mutation potentially altered splicing because it disrupted the splicing factor binding site. The kidney biopsy of the proband showed lamellation of the glomerular basement membrane (GBM), while IHC revealed negative α5(IV) staining in the GBM and Bowman's capsule, which is typical of XLAS. This is the first report of a synonymous COL4A5 substitution being responsible for XLAS. Our findings suggest that transcript analysis should be conducted for the future correct assessment of silent mutations.

  2. New morbidity of the young

    Full Text Available In the present phase of epidemiological transition, the most frequent causes of youth morbidity are disorders in reproductive health, mental disorders and injuries which are not life threatening. This, so-called new youth morbidity, is most often caused by their risky behavior, which in the field of sexuality often leads to unplanned pregnancies and abortions, as well as sexually transmitted infections. Misuse of tobacco, alcohol and narcotics, which is most commonly started in adolescence, has an unfavorable short-term and long-term influence on the psycho-physical health of the young. All research, in the world and in our country, indicate gradual yet constant growth of sexual activity of the youth and the age decrease of its starting point, especially when girls are in question. Due to insufficient maturity and inadequate knowledge and consciousness on the necessity of protecting reproductive health, sexual behavior of young people can often be characterized as insufficiently responsible and not supplemented with the usage of adequate protective measures. The result is frequently abortion, which terminates 90% of unplanned and unwanted pregnancies in this age. This creates health and psychosocial risks, as well as giving birth in adolescence which is contrary to the modern health concepts that giving birth should not be performed too early, while the young are still developing. A significant increase in the frequency of sexually transmitted diseases is also present, to which the youth are especially susceptible due to the specific development period in which they are in. A serious medical and sociopathological problem of contemporary society represents the greater and greater misuse of psychoactive substances among the young people, with a tendency of decreasing the average age they are consumed for the first time, as well as the use of drugs and alcohol. With the increase of the anti-smoking campaign and restrictive measures in highly

  3. The impact of living-unrelated transplant on establishing deceased-donor liver program in Syria.

    Liver transplant is the criterion standard for patients with end-stage liver disease. Yet there is no liver transplant in Syria. Traveling abroad for a liver transplant is a luxury few Syrians can afford. There is currently an on-going debate whether to start a liver transplant program using living or deceased donors. In 2003, a new law was enacted, authorizing the use of organs from volunteer strangers and deceased donors. Despite the positive aspects of this law (allowing unrelated donors to increase the number of transplants in the country); the negative aspects also were obvious. The poor used the law to sell their organs to the rich, and this model is in violation of the Istanbul Declaration. To better document transplant communities' perceptions on organ donation, an e-mail survey was sent to a nationally representative sample of physicians (n = 115) that showed that 58% of respondents did not support the start of liver transplant from live donors, as they fear a considerable risk for the donor and the recipient. Seventy-one percent of respondents believe that unrelated kidney donation has contributed to tarnishing the reputation of transplant, and 56% believe that a deceased-donor program can run in parallel with unrelated organ donations. The interest in deceased-donor program has been affected negatively by the systematic approach of using poor persons as the source of the organ. This lack of interest has affected starting a liver program that relies on deceased donors; especially the need for kidneys is more than livers. Health authorities in Syria were inclined to initiate a liver transplant program from live donors, despite the risks of serious morbidities and mortality. In conclusion then, paid kidney donation in actual effect is actually a hindrance to establishing a deceased-donor liver program.

    This study investigates the new phenomenon of parents of donor offspring searching for and contacting their child's 'donor siblings' (i.e. donor offspring conceived by the same donor) and donor. Online questionnaires were completed by 791 parents (39% lone-mother, 35% lesbian-couple, 21% heterosexual-couple, 5% non-specified) recruited via the Donor Sibling Registry; a US-based international registry that facilitates contact between donor conception families who share the same donor. Data were collected on parents' reasons for searching for their child's donor siblings and/or donor, the outcome of these searches and parents' and their child's experiences of any resulting contact. Parents' principal motivation for searching for their child's donor siblings was curiosity and for their donor, enhancing their child's sense of identity. Some parents had discovered large numbers of donor siblings (maximum = 55). Most parents reported positive experiences of contacting and meeting their child's donor siblings and donor. This study highlights that having access to information about a child's donor origins is important for some parents and has potentially positive consequences. These findings have wider implications because the removal of donor anonymity in the UK and elsewhere means that increasing numbers of donor offspring are likely to seek contact with their donor relations in the future.

    There is a national shortage of organs available for transplantation. Implementation of preset donor management goals (DMGs) to improve outcomes is recommended, but uniform practices and data are lacking. We hypothesized that meeting DMGs before organ procurement would result in more organs transplanted per donor (OTPD). The eight organ procurement organization in United Network for Organ Sharing Region 5 selected 10 critical care end points as DMGs. Each organ procurement organization submitted retrospective data from 40 standard criteria donors. "DMGs met" was defined as achieving any eight DMGs before procurement. The primary outcome was ≥4 OTPD. Binary logistic regression was used to determine independent predictors of ≥4 OTPD with a pdonors had 3.6±1.6 OTPD. Donors with DMGs met had more OTPD (4.4 vs. 3.3, p50% (OR=4.0), Pao2:FIO2>300 (OR=4.6), and serum sodium 135 to 160 mEq/L (OR=3.4). Meeting DMGs before procurement resulted in more OTPD. Donor factors and critical care end points are independent predictors of organ yield. Prospective studies are needed to determine the true impact of each DMG on the number and function of transplanted organs.

    Abstract In the context of limited donor pool in cardiothoracic transplantation, utilization of organs from high risk donors, such as suicidal hanging donors, while ensuring safety, is under consideration. We sought to evaluate the outcomes of lung transplantations (LTx) that use organs from this group. Between January 2011 and December 2015, 265 LTx were performed at our center. Twenty-two recipients received lungs from donors after suicidal hanging (group 1). The remaining 243 transplantations were used as a control (group 2). Analysis of recipient and donor characteristics as well as outcomes was performed. No statistically significant difference was found in the donor characteristics between analyzed groups, except for higher incidence of cardiac arrest, younger age and smoking history of hanging donors (P donor cause of death is not associated with poor mid-term survival or chronic lung allograft dysfunction following transplantation. These results encourage assessment of lungs from hanging donors, and their consideration for transplantation. PMID:29620623

    The present study explored the factors effective on colon-related morbidity in patients with penetrating injury of the colon. The medical records of 196 patients were reviewed for variables including age, gender, factor of trauma, time between injury and operation, shock, duration of operation, Penetrating Abdominal Trauma Index (PATI), Injury Severity Score (ISS), site of colon injury, Colon Injury Score, fecal contamination, number of associated intra- and extraabdominal organ injuries, units of transfused blood within the first 24 hours, and type of surgery. In order to determine the independent risk factors, multivariate logistic regression analysis was performed. Gunshot wounds, interval between injury and operation > or =6 hours, shock, duration of the operation > or =6 hours, PATI > or =25, ISS > or =20, Colon Injury Score > or = grade 3, major fecal contamination, number of associated intraabdominal organ injuries >2, number of associated extraabdominal organ injuries >2, multiple blood transfusions, and diversion were significantly associated with morbidity. Multivariate logistic regression analysis showed diversion and transfusion of > or =4 units in the first 24 hours as independent risk factors affecting colon-related morbidity. Diversion and transfusion of > or =4 units in the first 24 hours were determined to be independent risk factors for colon-related morbidity.

    Full Text Available OBJECTIVE: To assess results obtained with the authors' technique of right hand-assisted laparoscopic nephrectomy in living kidney donors. MATERIALS AND METHODS: We retrospectively analyzed 16 kidney donors who underwent hand-assisted right laparoscopic nephrectomy from February 2001 to July 2004. Among these patients, 7 were male and 9 were female, with mean age ranging between 22 and 58 years (mean 35.75. RESULTS: Surgical time ranged from 55 to 210 minutes (mean 127.81 min and warm ischemia time from 2 to 6 minutes (mean 3.78 min with mean intra-operative blood loss estimated at 90.62 mL. There was no need for conversion in any case. Discharge from hospital occurred between the 3rd and 6th days (mean 3.81. On the graft assessment, immediate diuresis was seen in 15 cases (93.75% and serum creatinine on the 7th post-operative day was 1.60 mg/dL on average. Renal vein thrombosis occurred in 1 patient (6.25% who required graft removal, and lymphocele was seen in 1 recipient (6.25%. CONCLUSION: Hand-assisted right laparoscopic nephrectomy in living donors is a safe and effective alternative to open nephrectomy. Despite a greater technical difficulty, the procedure presented low postoperative morbidity providing good morphological and functional quality of the graft on the recipient.

    2012-02-01

    OBJECTIVE: The purpose of this retrospective cohort study was to review pregnancy outcomes in morbidly obese women who delivered a baby weighing 500 g or more in a large tertiary referral university hospital in Europe. METHODS: Morbid obesity was defined as a BMI > or =40.0 kg\\/m2 (WHO). Only women whose BMI was calculated at their first antenatal visit were included. The obstetric out-comes were obtained from the hospital\\'s computerised database. RESULTS: The incidence of morbid obesity was 0.6% in 5,824 women. Morbidly obese women were older and were more likely to be multigravidas than women with a normal BMI. The pregnancy was complicated by hypertension in 35.8% and diabetes mellitus in 20.0% of women. Obstetric interventions were high, with an induction rate of 42.1% and a caesarean section rate of 45.3%. CONCLUSIONS: Our findings show that maternal morbid obesity is associated with an alarmingly high incidence of medical complications and an increased level of obstetric interventions. Consideration should be given to developing specialised antenatal services for morbidly obese women. The results also highlight the need to evaluate the effectiveness of prepregnancy interventions in morbidly obese women.

    IVF with donated oocytes, followed by embryo placement in the uterus of a recipient who has been primed with exogenous steroids, is a successful treatment for special cases of infertility. Preliminary results indicate that the success rate in this situation is even greater than that usually seen with normal IVF (with placement of the embryos back into the uteri of the women from whom the oocytes were recovered). Although different sources for donated oocytes have been identified, the use of "excess" oocytes from IVF cycles and the attempted collection of oocytes at the time of otherwise indicated pelvic surgery have ethical and practical problems associated with their use. We have herein described the establishment of a successful program relying on anonymous volunteers who go through ovarian stimulation, monitoring, and oocyte recovery procedures solely to donate oocytes. The potential donors go through an exhaustive screening and education process before they are accepted in the program. Psychological evaluation of our potential donors indicated a great degree of turmoil in their backgrounds and a wide variety of motivations for actually participating. Despite the extensive educational and screening process, a substantial percentage of the donors did not complete a donation cycle, having either voluntarily withdrawn or been dropped because of lack of compliance. Further investigation of the psychological aspects of participating in such a program is certainly warranted. The use of donated oocytes to alleviate specific types of infertility is quite successful, but the application of this treatment is likely to be limited by the relative unavailability of suitable oocyte donors.

    Informed consent of the patient to medical treatment is an essential prerequisite for any invasive medical procedure. However in emergency cases, when the patient is unable to sign a consent form due to unconsciousness or to psychotic state, than the primary medical consideration shall take place. In such a case, in order to save life or even prevent a major medical hazard to the patient, doctors are allowed, in certain cases and in accordance with well accepted medical practice, to perform invasive procedures, major surgery or risky pharmacological treatment, without the explicit consent of the patient. All the above refers to the cases when avoidance of such non-consented treatment may harm severely the health and wellbeing of the patient and there is no doubt that such treatment is for the ultimate benefit of the patient. The question, however, shall arise when such a medical procedure is not necessarily for the benefit of the patient, but rather for the benefit of somebody else. Such is the case in the transplantation area and the question of living donor-donee relationship. This paper shall analyze the legal situation in cases of non competent donors whose consent cannot be considered legal consent given in full understanding and out of free will. It will also compare three legal systems, the Israeli, the American and the traditional Jewish law, with regard to the different approaches to this human problem, where the autonomy of the donor may be sacrificed for the purpose of saving life of another person.

    A patient fulfilling the diagnostic criteria for systemic lupus erythematosus and presenting with morbid jealousy is described. There was evidence of cerebral lupus. Her physical and mental symptoms responded to a combination of chlorpromazine and steroids. The morbid mental process was probably caused by her physical condition while the content of her disordered thought and behaviour was determined by her introverted premorbid personality, religiosity, unhappy childhood experiences and frustrated desire for children.

    Allogeneic stem cell transplantation has been demonstrated to be curative in a wide variety of pediatric malignant and nonmalignant diseases, and can be traced back over 50 years ago to the original report of Thomas et al. HLA matched sibling donors have been the gold standard for pediatric recipients requiring allogeneic donors for both nonmalignant and malignant conditions. However, only 25% of potential pediatric recipients possesses an HLA-matched sibling donor, and the frequency is even less in those with genetic nonmalignant conditions because of genetically affected other siblings within the family. Therefore, 75% to 90% of potential pediatric recipients require alternative allogeneic donor cells for treatment of their underlying conditions. Potential alternative allogeneic donor sources include unrelated cord blood donors, unrelated adult donors, and haploidentical family donors. In this article we review the experience of both unrelated cord blood donor and haploidentical family donor transplants in selected pediatric malignant and nonmalignant conditions.

     Objective. The aim of this study was to compare the health-related quality of life (HRQoL) and self-esteem of patients who underwent split-thickness skin grafting, when either cellulose dressings or rayon dressings were applied to the donor sites. A total of 25 patients, who were enrolled at five participant hospitals and required split-thickness skin grafting for various clinical reasons, were randomized into two treatment groups, the rayon dressing group (n = 13), or the cellulose dressing group (n = 12). All patients were assessed preoperatively and 60 days postoperatively. The HRQoL was assessed with the Short Form-36 (SF-36) health survey questionnaire, and self-esteem was evaluated using the Rosenberg Self-Esteem Scale (RSE)/UNIFESP-EPM (Brazilian versions). There were no surgery-related complications during the study period. In both treatment groups, SF-36 scores for emotional role, mental health, vitality, and general health decreased from baseline. RSE scores increased from baseline in both treatment groups, showing a reduction in self-esteem after treatment. There was a statistical difference (P = 0.024) in the SF-36 bodily pain domain for the rayon group. There were no significant differences in HRQoL and self-esteem between treatment groups. In the rayon-dressing group, there was a significant decrease in bodily pain from baseline .

    Full Text Available Acceptance of elderly living kidney donors remains controversial due to the higher incidence of comorbidity and greater risk of postoperative complications. This is a review of publications in the English language between 2000 and 2013 about renal transplantation from elderly living donors to determine trends and effects of donation, and the outcomes of such transplantation. The last decade witnessed a 50% increase in living kidney donor transplants, with a disproportionate increase in donors >60 years. There is no accelerated loss of kidney function following donation, and the incidence of established renal failure (ERF and hypertension among donors is similar to that of the general population. The overall incidence of ERF in living donors is about 0.134 per 1000 years. Elderly donors require rigorous assessment and should have a predicted glomerular filtration rate of at least 37.5 mL/min/1.73 m2 at the age of 80. Though elderly donors had lower glomerular filtration rate before donation, proportionate decline after donation was similar in both young and elderly groups. The risks of delayed graft function, acute rejection, and graft failure in transplants from living donors >65 years are significantly higher than transplants from younger donors. A multicentred, long-term, and prospective database addressing the outcomes of kidneys from elderly living donors is recommended.

    Due to the shortage of deceased donor organs, transplant centers accept organs from marginal deceased donors, including older donors. Organ-specific donor risk indices have been developed to predict graft survival using various combinations of donor and recipient characteristics. We will review the kidney donor risk index (KDRI) and liver donor risk index (LDRI) and compare and contrast their strengths, limitations, and potential uses.

    2008-01-01

    Full Text Available OBJECTIVE: There is limited information about how morbidly obese osteoarthritis (OA patients cope with the pain they experience. Pain catastrophizing is an important predictor of pain and adjustment in persons with persistent pain. This may be particularly relevant in the morbidly obese (body mass index [BMI] of 40 kg/m2 or greater OA population at risk for increased pain. The present study first examined whether borderline morbidly obese and morbidly obese OA patients report higher levels of pain catastrophizing than a sample of OA patients in the overweight and obese category (BMI between 25 kg/m2 and 34 kg/m2. Next, it examined how pain catastrophizing is related to important indexes of pain and adjustment in borderline morbidly obese and morbidly obese OA patients.

  12. Maternal morbidities affect tens of millions.

    Science.gov (United States)

    Finger, W R

    1994-02-01

    Various separate studies indicate maternal morbidity is more common than had been believed. A Safe Motherhood Survey was conducted in 1993 in the Philippines among 9000 women, as part of efforts to study women's language and perceptions about pregnancy and symptoms of morbidity. In El Salvador, interviews were conducted among 2000 women on morbidity issues. Preliminary results from a Family Health International (FHI) five-country survey of 16,000 women revealed that 7 out of every 10 women reported a health problem related to maternity or chronic conditions stemming from pregnancy or childbirth. Conditions ranged from obstructed labor, complications from unsafe abortions, and bacterial infections, to anemia, hemorrhage, and eclampsia. The quality of care determines whether the health problems are life threatening. Less serious morbidity cases involve fatigue or back pain, which is exacerbated by poor nutrition and hard physical labor. Other reproductive morbidities are sexually transmitted diseases, side effects from contraceptives, and general gynecological problems. The FHI results from Ghana, Indonesia, and Egypt showed 240-300 morbidities for every maternal death; maternal mortality worldwide is estimated at 500,000 annually. A study of fistula (an injury during labor to the vagina and bladder that results in urinary or fecal incontinence) found that Nigerian community norms and limited access to emergency health care were factors. The women reported costs, poor roads, and transportation problems. A study in Ethiopia found that, in an Addis Ababa hospital between 1983-88, 600 fistulas were repaired every year, of which almost 66% occurred at first delivery. A study in Cairo in 1988 found that nearly 6 out of every 10 women reported a prolapsed uterus. Women in the studies were able to talk openly and willingly about their problems, when concepts and language were appropriate and interviewers were trained. A small study in India confirmed the correlation between

    Co-morbidities of vertiginous diseases have so far not been investigated systematically. Thus, it is still unclear whether the different vertigo syndromes (e.g. benign paroxysmal positional vertigo (BPPV), Meniere's disease (MD), vestibular migraine and phobic vertigo (PPV)) have also different spectrums of co-morbidities. All patients from a cohort of 131 participants were surveyed using a standardised questionnaire about the co-morbidities hypertension, diabetes mellitus, BMI (body mass index), migraine, other headache, and psychiatric diseases in general and the likelihood of a depression in particular. We noted hypertension in 29.0% of the cohort, diabetes mellitus in 6.1%, migraine in 8.4%, other headache in 32.1%, psychiatric diseases in 16.0%, overweight and obesity in 33.6% and 13.7% respectively, as well as a clinical indication for depression in 15.9%. In general, we did not detect an increased prevalence of the co-morbidities diabetes mellitus, arterial hypertension, migraine, other headache and obesity compared to the general population. There was an increased prevalence of psychiatric co-morbidity in patients with PPV, and the prevalence of hypertension was elevated in patients with MD.

    Full Text Available OBJECTIVE: To present the initial experience of videolaparoscopic nephrectomy in live renal donor. MATERIALS AND METHODS: In the period from April 2000 to August 2003, 50 left nephrectomies in live donor were performed by videolaparoscopy for transplantation. Twenty-eight patients were male (56% and 22 female (44%. Mean age was 37.2 years, and the mean body mass index (BMI was 27.1 kg/m². RESULTS: Mean surgical time was 179.5 minutes, and warm ischemia time of the graft was 3.79 minutes. The mean estimated bleeding was 141 mL. There was no need of blood transfusion or conversion to open surgery. In 42 cases (84%, the vascular portion of the graft was considered good by the recipient's surgical team and in all cases, the ureter was considered of proper size, though in one of them (2% its vascularization was considered improper. The transplanted kidneys produced urine still in the surgical room in 46 of the 50 transplantations considered. In only 2 cases opioid was required for analgesia. In average, 3.1 doses of dipyrone were used for each patient during hospital stay, and hospital discharge occurred, in average, after 3.2 days post-operatively. Two patients required re-operations and one of them evolved to death. CONCLUSIONS: The laparoscopic nephrectomy in live donor for renal transplantation is an alternative to conventional open surgery. In relation to the graft, no alteration, either anatomic or functional, was detected. Though there is already a large documentation in the international literature regarding this procedure, in our setting a prospective randomized study with the usual surgical study is still necessary in order to prove the advantages and disadvantages of the method.

    Cytomegalovirus (CMV) and Epstein-Barr virus (EBV) infections remain a major cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT). The adoptive transfer of donor-derived viral-specific cytotoxic T-cells (VSTs) is an effective treatment for controlling CMV and EBV infections after HSCT; however, new practical methods are required to augment the ex vivo manufacture of multi-VSTs from healthy donors. This study investigated the effects of a single exer...

    For many decades, hemagglutination has been the sole means to type blood donors. Since the first blood group gene cloning in the early 1990s, knowledge on the molecular basis of most red blood cell, platelet and neutrophil antigens brought the possibility of using nucleotide-based techniques to predict phenotype. This review will summarized methodologies available to genotype blood groups from laboratory developed assays to commercially available platforms, and how proficiency assays become more present. The author will also share her vision of the transfusion medicine future. The field is presently at the crossroads, bringing new perspectives to a century old practice. Copyright © 2014 Elsevier Ltd.

    Postmortem studies have demonstrated that morbidly obese subjects, surprisingly, have less coronary atherosclerosis than obese subjects. However, the reasons for this apparent protection from atherosclerosis are not yet clear. Thromboxane A2, a marker of platelet activation, is greater in obese subjects than in lean subjects, and this might be a clue to their increased cardiovascular risk. However, data on thromboxane A2 in morbidly obese subjects are lacking; therefore, we hypothesized that lower levels of thromboxane A2 in morbidly obese subjects might play a role in their lower atherothrombotic burden. We measured the serum levels of thromboxane B2 (TxB2), a stable metabolite of thromboxane A2, high-sensitivity C-reactive protein (hs-CRP) and leptin in 17 lean subjects (body mass index [BMI] 22.9 ± 1.6 kg/m(2)), 25 obese subjects (BMI 32.6 ± 2.4 kg/m(2)), and 23 morbidly obese subjects (BMI 48.6 ± 7.1 kg/m(2)), without insulin resistance, diabetes, or overt cardiovascular disease. The serum TxB2 levels were lower in the lean subjects than in the obese subjects (p = 0.046) and in the morbidly obese subjects than in the lean and obese subjects (p = 0.015 and p lean subjects (hs-CRP, p lean subjects (p lean subjects, suggesting that reduced platelet activation could play a role in the paradoxical protection of morbidly obese subjects from atherosclerosis, despite the greater levels of leptin.

    2009-01-01

    Derivatives of N-pyrrolobenzene with a para-donor and a para-acceptor substituent on the benzene ring are compared. It is shown that by a suitable increase of the donor strength of the pyrrolo group, CT fluorescence can be achieved even for donor-donor-substituted benzenes. The ICT emission for sterically hindered compounds is more forbidden than that of unhindered phenyl pyrroles. This suggests conformational effects which induce a narrower twist angle distribution around a perpendicular minimum in the excited state.

  4. Alternative Donor Graft Sources for Adults with Hematologic Malignancies: A Donor for All Patients in 2017!

    Kindwall-Keller, Tamila L; Ballen, Karen K

    2017-09-01

    Hematopoietic stem cell transplant (HSCT) is potentially curative for a wide variety of malignant diseases, including acute and leukemias, lymphoma, and myelodysplasia. Choice of a stem cell donor is dependent on donor availability, donor compatibility and health, recipient disease type, and recipient condition. Current sources of stem cell donation for HSCT are matched sibling donors (MSDs), matched unrelated donors (MUDs), 1-antigen mismatched unrelated donors (MMUDs), haploidentical donors (haplo), and umbilical cord blood (UCB) units. Historically, preferred donors for HSCT have been human leukocyte antigen (HLA)-matched sibling donors; however, only about 30% of U.S. patients will have a MSD available. The majority of patients referred for HSCT will require an alternative donor graft: MUD, MMUD, UCB, or haplo. The likelihood of finding a MUD varies depending on the ethnicity of the recipient. White Caucasians of European descent have the greatest chance of finding a MUD. Chances of finding a MUD are significantly less for African-American or Hispanic recipients due to HLA polymorphisms. Therefore, MMUD, UCB, and haplo donor graft sources expand the donor pool for recipients who do not have a MSD or MUD available. Given the variety of different donor stem cell sources available today, nearly every patient who needs an allogeneic HSCT has a potential donor in 2017. All transplant-eligible patients with hematologic malignancies should be evaluated by a transplant center to determine if HSCT is a viable treatment option for their underlying disease process. The goal of this review is to increase the awareness of oncology practitioners to the availability of alternative donor stem cell transplants for patients with hematologic malignancies. Despite new agents, stem cell transplant remains the only curative therapy for many patients with acute and chronic leukemia, myelodysplasia, and lymphoma. Given the variety of different donor stem cell sources available today

    A novel strategy is reported for the fabrication of bis-aniline-crosslinked Au nanoparticles (NPs)-CdSe/ZnS quantum dots (QDs) array composite by facil one-step co-electropolymerization of thioaniline-functionalized AuNPs and thioaniline-functionalized CdSe/ZnS QDs onto thioaniline-functionalized Au elctrodes (AuE). Stable and enhanced cathodic electrochemiluminescence (ECL) of CdSe/ZnS QDs is observed on the modified electrode in neutral solution, suggesting promising applications in ECL sensing. An advanced ECL sensor is explored for detection of 2-methyl-4-chlorophenoxyacetic acid (MCPA) which quenches the ECL signal through electron-transfer pathway. The sensitive determination of MCPA with limit of detection (LOD) of 2.2 nmolL(-1) (S/N=3) is achieved by π-donor-acceptor interactions between MCPA and the bis-aniline bridging units. Impressively, the imprinting of molecular recognition sites into the bis-aniline-crosslinked AuNPs-CdSe/ZnS QDs array yields a functionalized electrode with an extremely sensitive response to MCPA in a linear range of 10 pmolL(-1)-50 μmolL(-1) with a LOD of 4.3 pmolL(-1 ()S/N=3). The proposed ECL sensor with high sensitivity, good selectivity, reproducibility and stability has been successfully applied for the determination of MCPA in real samples with satisfactory recoveries. In this study, ECL sensor combined the merits of QDs-ECL and molecularly imprinting technology is reported for the first time. The developed ECL sensor holds great promise for the fabrication of QDs-based ECL sensors with improved sensitivity and furthermore opens the door to wide applications of QDs-based ECL in food safety and environmental monitoring.

    Although national guidelines exist for evaluating the eligibility of potential living donors and for procuring their informed consent, no special protections or considerations exist for potential living donors who are incarcerated. Human research subject protections in the United States are codified in the Federal Regulations, 45 CFR 46, and special protections are given to prisoners. Living donor transplantation has parallels with human subject research in that both activities are performed with the primary goal of benefiting third parties. In this article, we describe what special considerations should be provided to prisoners as potential living donors using a vulnerabilities approach adapted from the human research subject protection literature.

    We sought to examine neonatal morbidity associated with different maneuvers used among term patients who experience a shoulder dystocia. We conducted a retrospective cohort study of all women who experienced a clinically diagnosed shoulder dystocia at term requiring obstetric maneuvers at a single tertiary care hospital from 2005 through 2008. We excluded women with major fetal anomaly, intrauterine death, multiple gestation, and preterm. Women exposed to Rubin maneuver, Wood's screw maneuver, or delivery of the posterior arm were compared to women delivered by McRoberts/suprapubic pressure only, which served as the reference group. The primary outcome was a composite morbidity of neonatal injury (defined as clavicular or humeral fracture or brachial plexus injury) and neonatal depression (defined as Apgar dystocia, defined as time from delivery of fetal head to delivery of shoulders. Among the 231 women who met inclusion criteria, 135 were delivered by McRoberts/suprapubic pressure alone (57.9%), 83 women were exposed to Rubin maneuver, 53 women were exposed to Wood's screw, and 36 women were exposed to delivery of posterior arm. Individual maneuvers were not associated with composite morbidity, neonatal injury, or neonatal depression after adjusting for nulliparity and duration of shoulder dystocia. We found no association between shoulder dystocia maneuvers and neonatal morbidity after adjusting for duration, a surrogate for severity. Our results demonstrate that clinicians should utilize the maneuver most likely to result in successful delivery. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Morbidly adherent placentas are a spectrum of abnormalities ranging from placental invasion of the myometrium to invasion past the myometrium and muscular layers into adjacent structures. This entity is becoming more prevalent recently with increased number of cesarean deliveries. Given the high risk of morbidity and mortality, this was traditionally treated with pre-term planned cesarean hysterectomy. However, recently, uterine preservation techniques have been implemented for those women wishing to preserve future fertility or their uterus. Early identification is crucial as studies have shown better outcomes for women treated at tertiary care facilities by a dedicated multidisciplinary team. Interventional radiologists are frequently included in the care of these patients as there are several different endovascular techniques which can be implemented to decrease morbidity in these patients both in conjunction with cesarean hysterectomy and in the setting of uterine preservation. This article will review the spectrum of morbidly adherent placentas, imaging, as well as the surgical and endovascular interventions implemented in the care of these complex patients.

    Full Text Available Research Question: What is the sickness prevalence in the slums of a metropolitan city? Objectives: To estimate the morbidity prevalence with reference to a socio-economic and demographic perspective of the slum population of Delhi. Study Design: A cross-sectional study was conducted and data were collected by a two-stage random sampling method. In the first stage, slum locations were selected and in the second stage households were selected. Participants: Data were collected from 1049 households consisting of 5358 individuals′ information. Results: The overall morbidity prevalence is 15.4%. It is 14.7 and 16.3% for males and females, respectively but the differences are not statistically significant. The reported higher morbidity prevalence and the illiteracy status are significantly associated. Diseases of the respiratory system appear to be very high among slum dwellers. Conclusion: From this study, it can be concluded that the number of years of staying in the slum area, presence of a separate kitchen, type of house, it being Pucca or Kuccha, types of toilet pits or open defecation are the important environmental factors for the reports of higher morbidity patterns from the slum area.

    Brain death is a major stress that is associated with a massive inflammatory response and systemic hyperglycemia. Severe inflammation leads to increased graft immunogenicity and risk of graft dysfunction; while acute hyperglycemia aggravates the inflammatory response and increases the risk of morbidity and mortality. Insulin therapy not only controls hyperglycemia but also suppresses inflammation. The present study is to investigate the anti-inflammatory properties and the normoglycemia maintenance of high dose insulin on brain dead organ donors. 15 brain dead organ donors were divided into 2 groups, insulin treated (n=6) and controls (n=9). Insulin was provided for a minimum of 6 h using the hyperinsulinemic normoglycemic clamp technique. The changes of serum cytokines, including IL-6, IL-10, IL-1β, IL-8, TNFα, TGFα and MCP-1, were measured by suspension bead array immunoassay and glucose by a glucose monitor. Compared to controls, insulin treated donors had a significant lower blood glucose 4.8 (4-6.9) vs. 9 (5.6-11.7) mmol/L, pinsulin treated donors compared with those in controls. High dose insulin therapy decreases the concentrations of inflammatory cytokines in brain dead donors and preserves normoglycemia. High dose of insulin may have anti-inflammatory effects in brain dead organ donors and therefore, improve the quality of donor organs and potentially improve outcomes. © Georg Thieme Verlag KG Stuttgart · New York.

    Liver transplants, originally obtained from deceased donors, can now be harvested from living donors as well. This technique, called living-donor liver transplantation (LDLT), provides an effective alternative means of liver transplantation and is a method of expanding the donor pool in light of the demand and supply imbalance for organ transplants. Imaging plays an important role in LDLT programmes by providing robust evaluation of potential donors to ensure that only anatomically suitable donors with no significant co-existing pathology are selected and that crucial information that allows detailed preoperative planning is available. Imaging evaluation helps to improve the outcome of LDLT for both donors and recipients, by improving the chances of graft survival and reducing the postoperative complication rate. In this review, we describe the history of LDLT and discuss in detail the application of imaging in donor assessment with emphasis on use of modern computed tomography (CT) and magnetic resonance imaging (MRI) techniques

    Cytomegalovirus (CMV) infection remains a major cause of morbidity after lung transplantation. Some studies have reported prognostic factors for the postoperative development of CMV infection in cadaveric lung transplantation (CLT), but no research has been performed in living-donor lobar lung transplantation (LDLLT). Therefore, we analysed the possible risk factors of post-transplant CMV infection and the differences between LDLLT and CLT. The development of CMV disease and viraemia in 110 patients undergoing lung transplantation at Kyoto University Hospital in 2008-2015 were retrospectively assessed. The prognostic factors in the development of CMV infection and the differences between LDLLT and CLT were analysed. Among 110 patients, 58 LDLLTs and 52 CLTs were performed. The 3-year freedom rates from CMV disease and viraemia were 92.0% and 58.5%, respectively. There was no difference in the development of CMV infection between LDLLT and CLT (disease: 94.6% vs 91.0%, P = 0.58 and viraemia: 59.3% vs 57.2%, P = 0.76). In preoperative anti-CMV immunoglobulin status, R-D+ recipients (recipient: negative, donor: positive) and R-D- recipients (recipient: negative, donor: negative) tended to have higher and lower cumulative incidences, respectively, of CMV infection (disease: P = 0.34 and viraemia: P = 0.24) than that with R+ recipients (recipient: seropositive). Significantly lower cumulative incidence of CMV viraemia was observed in patients receiving 12-month prophylactic medication (70.6% vs 36.8%, P CLT. We found that there was no difference in the development of CMV infection between LDLLT and CLT. Twelve-month prophylaxis protocol provides beneficial effect without increased toxicity also in LDLLT. © The Author 2017.

    Both donors and non-donors have a positive image of blood donation, so donors and non-donors do not differ regarding their views on donation but do differ in converting their opinion into an active deed of donation. Several studies have identified altruism and empathy as the main factors underlying blood donation. However, a mixture of various motivational factors mould the complex behaviour of donation. This paper presents an exploratory study on differences of social representations of blood donation between blood donors and non-donors, in order to understand the reasons that bring someone to take the decision to become a blood donor. Participants filled in the Adapted Self-Report Altruism Scale, Toronto Empathy Questionnaire and answered a test of verbal association. Descriptive and correlation analyses were carried out on quantitative data, while a prototypic analysis was used for qualitative data. The study was carried out on a convenience sample of 786 individuals, 583 donors (mean age: 35.40 years, SD: 13.01 years; 39.3% female) and 203 non-donors (mean age: 35.10 years, SD: 13.30 years; 67.5% female). Social representations of donors seem to be more complex and articulated than those of non-donors. The terms that appear to be central were more specific in donors (life, needle, blood, help, altruism were the words most associated by non-donors; life, aid, altruism, solidarity, health, love, gift, generosity, voluntary, control, needed, useful, needle were the words most associated by donors). Furthermore, non-donors associated a larger number of terms referring to negative aspects of blood donation. Aspects related to training and the accuracy of any information on blood donation seem to be important in the decision to become a donor and stabilise the behaviour of donation over time, thus ensuring the highest levels of quality and safety in blood establishments.

    Maternal morbidity refers to pregnancy-related complications, ranging in severity from acute to chronic. In Ireland one in 210 maternities will experience a severe morbidity. Yet, how women internalize their experience of morbidity has gone largely unexplored. This study aimed to explore women\\'s experiences of maternal morbidity.

  19. Cost and Cost-Effectiveness of Donor Human Milk to Prevent Necrotizing Enterocolitis: Systematic Review.

    2017-11-01

    Necrotizing enterocolitis (NEC) is a costly gastrointestinal disorder that mainly affects preterm and low-birth-weight infants and can lead to considerable morbidity and mortality. Mother's own milk is protective against NEC but is not always available. In such cases, donor human milk has also been shown to be protective (although to a lesser extent) compared with formula milk, but it is more expensive. This systematic review aimed at evaluating the cost of donor milk, the cost of treating NEC, and the cost-effectiveness of exclusive donor milk versus formula milk feeding to reduce the short-term health and treatment costs of NEC. We systematically searched five relevant databases to find studies with verifiable costs or charges of donor milk and/or treatment of NEC and any economic evaluations comparing exclusive donor milk with exclusive formula milk feeding. All search results were double screened. Seven studies with verifiable donor milk costs and 17 with verifiable NEC treatment costs were included. The types of cost or charge included varied considerably across studies, so quantitative synthesis was not attempted. Estimates of the incremental length of stay associated with NEC were ∼18 days for medical NEC and 50 days for surgical NEC. Two studies claimed to report economic evaluations but did not do so in practice. It is likely that donor milk provides short-term cost savings by reducing the incidence of NEC. Future studies should provide more details on cost components included and a full economic evaluation, including long-term outcomes, should be undertaken.

    This study investigates a new phenomenon whereby individuals conceived by donor insemination are searching for and contacting their donor and/or 'donor siblings' (i.e. donor offspring conceived by the same donor who are their genetic half siblings). On-line questionnaires were completed by members of the Donor Sibling Registry (DSR), a US-based registry that facilitates contact between donor conception families who share the same donor. Of the 165 donor offspring who completed the survey, 15% were searching for their donor siblings, 13% were searching for their donor, and 64% were searching for both. Differences were found according to family type and age of disclosure. Fewer offspring from heterosexual couple families had told their father about their search when compared with offspring from lesbian couple families who had told their co-parent. Offspring who had found out about their conception after age 18 were more likely to be searching for medical reasons, whereas those who had found out before age 18 tended to be searching out of curiosity. Some offspring had discovered large numbers of half siblings (maximum=13). The majority of offspring who had found their donor relations reported positive experiences and remained in regular contact with them. Copyright (c) 2010 Reproductive Healthcare Ltd.

    Efforts to promote organ donation have traditionally relied on mass-mediated or interpersonal communication to promote donor registration. Despite its popularity, the use of online media has yet to be carefully evaluated as a platform to promote organ donation. To describe results of an intervention to promote donor registration that relies solely on online media to communicate to target audiences. For 3 years, 6 campaigns were implemented in 3 different online media formats. Online media formats included (1) traditional online advertising, (2) student seeders' social networking sites campaigns, and (3) challenge campaigns. Online media campaigns primarily targeted college-aged individuals.Intervention-Each campaign directed individuals to the dedicated project website, where they could access educational material about donation and request a donor registration card. Unique website visitors, webpages viewed per site visit, time spent on site, and organ donor cards requested/received were tracked in relation to each online media format. Traditional online advertising offered greater message exposure but failed to result in a higher proportion of website visitors who registered their donation intentions. Use of student seeders (ie, motivated students who promote donation by using social networking sites) and challenge campaigns resulted in greater attention to the project website, donor card requests, and subsequent returns. Additional research is recommended to reveal the effect of combining 2 or more varying online media formats within a single campaign.

    Due to the shortage of deceased donor organs, transplant centers accept organs from marginal deceased donors, including older donors. Organ-specific donor risk indices have been developed to predict graft survival using various combinations of donor and recipient characteristics. We will review the kidney donor risk index (KDRI) and liver donor risk index (LDRI) and compare and contrast their strengths, limitations, and potential uses. The Kidney Donor Risk Index has a potential role in developing new kidney allocation algorithms. The Liver Donor Risk Index allows for greater appreciation of the importance of donor factors, particularly for hepatitis C-positive recipients; as the donor risk index increases, rates of allograft and patient survival among these recipients decrease disproportionately. Use of livers with high donor risk index is associated with increased hospital costs independent of recipient risk factors, and transplanting livers with high donor risk index into patients with Model for End-Stage Liver Disease scores Donor Risk Index has limited this practice. Significant regional variation in donor quality, as measured by the Liver Donor Risk Index, remains in the United States. We also review other potential indices for liver transplant, including donor-recipient matching and the retransplant donor risk index. While substantial progress has been made in developing donor risk indices to objectively assess donor variables that affect transplant outcomes, continued efforts are warranted to improve these indices to enhance organ allocation policies and optimize allograft survival.

    The National AIDS Control Organization (NACO), the apex body for controlling AIDS in India, projected that HIV seroprevalence would increase from 7/1000 in 1995 to 21.2/1000 in 1997. A high incidence (8.2%) of HIV was observed in blood donors. This study was carried out to find out the true HIV positivity in Indian blood donors. Blood donors from our centre were followed for more than 5 years to determine the true HIV seroprevalence and our result was compared with similar studies from India. Voluntary and relative blood donors who visited the SGPGIMS, Lucknow, since 1993 to June 1998 were included. They were screened for HIV 1/2 by ELISA kits (WHO approved). First-time HIV-positive samples were preserved frozen for further study (stage-I). They were repeated in duplicate and retested with other kits. If found positive, the sample was labelled as ELISA positive (stage-II). ELISA-positive samples were confirmed by Western Blot (WB) at stage-III. A total of 65 288 donors were included and 834 (12.8/1000) were reactive at stage-I. But 1.1/1000 donors were found to be ELISA positive at stage-II, and 0.28/1000 donors were positive by WB at stage-III. The 'seropositivity' rate from the NACO was significantly (P commercial blood banks. The HIV prevalence of blood donors (and national prevalence) is to be reassessed.

    This paper documents how couples and providers access donor materials for conception in the Indian context and perceptions about using them. The objective is to facilitate understanding of critical issues and relevant concerns. A postal survey was conducted with a sample of 6000 gynaecologists and in-depth interviews were -conducted with 39 gynaecologists in four cities. Donor gametes are relatively more acceptable than a few years ago, especially if confidentiality can be -maintained, though lack of availability of donor materials is sometimes an impediment to infertility treatment. Donor sperms are usually accessed from in-house or commercial sperm banks, pathology laboratories, IVF centres, -professional donors, relatives or friends. There is scepticism about screening procedures of sperm banks. Donor eggs are usually accessed from voluntary donors, friends, relatives, egg sharing programmes, donation from other patients, advertising and commercial donors. There are several concerns regarding informed consent for using donated gametes, using -relatives and friends gametes, the unregulated use of gametes and embryos, record keeping and documentation, -unethical and corrupt practices and commercialisation. These issues need to be addressed by patients, providers and regulatory authorities by providing -information, counselling, ensuring informed consent, addressing exploitation and commercialisation, ensuring -monitoring, proper documentation and transparency.

    A North Carolinian developed fatal coccidioidomycosis immediately after bilateral lung transplantation. The donor had previously traveled to Mexico, and the recipient had no travel history to an area where Coccidioides immitis is endemic. Immunosuppresive therapy of the transplant recipient likely reactivated latent Coccidioides infection in the donor lungs, leading to posttransplant coccidioidomycosis.

    2006-01-01

    Irrespectively of universal shortage of donor organs there is a tendency of increasing the number of transplantations from living and deceased donors. Each of these two methods has positive and negative features. The main obstacles using living donors are health hazard, necessity to solve certain donor's social and psychological problems, possibility of organ trade and moving. The main problems connected with organ retrieval from deceased donors are possible conflicts with public opinion: difficulties in interpretation of brain death, legislation, obtaining of informed consent from donor's relatives, etc. Future progress in organ transplantation may take place through activation of organ retrieval from deceased donors. The most perspective ways are change to presumed consent in all countries, establishing of centralized system of donor detection and registration, intensification of transplant coordination, active contacts with mass-media, etc. It is necessary to increase (enhance) participation of the members of the public in organ donation process, to develop solidarity among the public members and to involve public authorities to deal with this problem. Bioethical standards should be put in accordance with common progress and some ethical traditions should be changed.

    Full Text Available Abstract Background The heart transplant is a treatment of the heart failure, which is not responding to medications, and its efficiency is already proved: unfortunately, organ donation is a limiting step of this life-saving procedure. To counteract heart donor shortage, we should screen aged potential donor hearts for initial cardiomyopathy and functionally significant coronary artery disease. Donors with a history of cardiac disease are generally excluded. Coronary angiography is recommended for most male donors older than 45 years and female donors older than 50 years to evaluate coronary artery stenoses. A simpler way to screen aged potential donor hearts for initial cardiomyopathy and functionally significant coronary artery disease should be stress echocardiography. Case report A marginal donor (A 57 year old woman meeting legal requirements for brain death underwent a transesophageal (TE Dipyridamole stress echo (6 minutes accelerated protocol to rule out moderate or severe heart and coronary artery disease. Wall motion was normal at baseline and at peak stress (WMSI = 1 at baseline and peak stress, without signs of stress inducible ischemia. The pressure/volume ratio was 9.6 mmHg/ml/m2 at baseline, increasing to 14 mmHg/ml/m2 at peak stress, demonstrating absence of latent myocardial dysfunction. The marginal donor heart was transplanted to a recipient "marginal" for co-morbidity ( a 63 year old man with multiple myeloma and cardiac amyloidosis , chronic severe heart failure, NYHA class IV. Postoperative treatment and early immunosuppressant regimen were performed according to standard protocols. The transplanted heart was assessed normal for dimensions and ventricular function at transthoracic (TT echocardiography on post-transplant day 7. Coronary artery disease was ruled out at coronary angiography one month after transplant; left ventriculography showed normal global and segmental LV function of the transplanted heart.

    2010-11-01

    As increasing demand for organs is a challenge for transplant services worldwide it is essential to audit the process of organ donation. To address this, a national audit of potential organ donors was undertaken across hospitals with Intensive Care Units (N = 36). Questionnaires were returned on all patients (n = 2073) who died in these units from 1\\/9\\/07-31\\/8\\/08; 200 (10%) of these patients were considered for Brain Stem Testing (BST), 158 patients (79%) were diagnosed Brain Stem Dead (BSD) and 138 patients (87%) became potential donors. Consent for donation was given by 92 (69%) next of kin and 90 potential donors (65%) became organ donors. There was no evidence of a large number of potential organ donors being missed. Recommendations included completion of BSTs on all appropriate patients, development of support on BST, referral of all BSD patients to the Organ Procurement Service; enhanced co-ordination within hospitals and sustained information\\/education campaigns.

    Full Text Available There is well known fact that kidney transplants from Extended Criteria Donors may increase risk of De- layed Graft Function and Primary Non-Function of transplants. We have collected and tested 65 «zero» kidney biopsies from cadaver donors aged from 19 to 71 years old. In the pool of elderly donors who died from cerebrovascular accident the frequency of nephrosclerosis presentation was higher than in donors of yonger age who died from craniocephalic trauma. Nevertheless in the general donor pool the number of sclerosed glomeruli was no more than 12%. We did not meet at all in the whole volume of material any bi- opsy with the severe degree of arteriosclerosis. The «zero» biopsies of cadaver kidneys is quite usable and unexpensive tool to measure the degree of nephrosclerosis in order to exclude kidneys which are not fitable for transplantation.

    Neonatal morbidity was higher among the babies of 521 women who were gainfully employed during pregnancy compared to those of 475 non working women of the same area (Aarau, Switzerland). The difference was lower (6%) in the part time employed than in those working full time (11%.) It was almost entirely due to the higher number of primiparae and of smokers among those women who were working during pregnancy.

    The main objective of the work presented herein is to assess the effect of different electron donors (butyric acid and methanol) on the dechlorinating activity of two microbial cultures where active methanogenic populations are present, in an effort to evaluate the importance of the electron donor selection process. The ability of each anaerobic culture to dechlorinate TCE, when enriched with either butyric acid or methanol, was verified based on the results of gas chromatography. In addition, the fluorescent in situ hybridization (FISH) and the polymerase chain reaction (PCR) methods gave positive results for the presence of Dehalococcoides spp. According to results of the batch tests conducted in this study, it appears that the selection of the electron donor for stimulating TCE dechlorination depends on microbial culture composition; therefore, the decision on the appropriate electron donor should be based on site-specific microcosm studies

    In this exploratory qualitative study of 11 young adults, ages 19-29 years, we examine how young people who were raised by lesbian parents make meaning out of and construct their relationships with known donors. In-depth interviews were conducted to examine how participants defined their family composition, how they perceived the role of their donors in their lives, and how they negotiated their relationships with their donors. Findings indicate that mothers typically chose known donors who were family friends, that the majority of participants always knew who their donors were, and that their contact with donors ranged from minimal to involved. Further, participants perceived their donors in one of three ways: as strictly donors and not members of their family; as extended family members but not as parents; and as fathers. The more limited role of donors in participants' construction of family relationships sheds light on how children raised in lesbian, gay, and bisexual families are contributing to the redefinition and reconstruction of complex kinship arrangements. Our findings hold implications for clinicians who work with lesbian-mother families, and suggest that young adulthood is an important developmental phase during which interest in and contact with the donor may shift, warranting a transfer of responsibility from mother to offspring in terms of managing the donor-child relationship. © FPI, Inc.

    The objectives of this study are to evaluate the surgical management, both definitive and palliative, in selected patients with biliary obstruction and to find out the postoperative morbidity and mortality in these patients. Duration of the study is two years conducted from June 2002 to May 2004. The study was carried out at. the surgical. unit 4 of the Combined Military Hospital and surgical department of the Military Hospital. Thirty eight cases of biliary obstruction were included. A convenient sampling technique was followed. Data analyzed by using SPSS version 10.0 for windows on computer. Descriptive statistics like frequency, percentage, average etc were computed for data presentation. Any inferential test-was not found to be applicable for this descriptive type case series. We selected 38 patients with features of extrahepatic biliary obstruction. Out of these (n 38) 15 patients (39.5%) suffered from benign diseases while those having malignant diseases were 23 (60.5%). 19 (50%) patients died within two years of follow up while 19 (50%) were the survivors. Mortality was maximum for the malignant cases. In benign cases only one patient died. Maximum deaths 6 (31.6%) occurred in the period of up to one month of operation. 20 patients had one or another complication of operation and hence the morbidity came out to be 52%. According to our results the mortality and morbidity related to extrahepatic biliary obstruction in our patients was higher compared to other studies which can only be reduced by early detection and treatment.

Such studies would permit earlier detection and more sensitive measures of differences in risk for exposures to radiation and allow timely measures to be taken to minimize any occupational and environmental health risk to radiation workers. The technical feasibility of using these sources was reviewed using the criteria of adequate personal identifying information, automation of data records, file size and the accuracy of the morbidity diagnosis information. At the present time certain of the provincial cancer registry files meet these criteria best. A work plan was prepared suggesting a morbidity pilot study to clarify the role of occupational factors in the incidence of cancer among radiation workers using the Alberta Cancer Registry file and the National Dose Registry (NDR) file of radiation workers. For the longer term a full cohort study using the National Cancer Incidence Reporting System (NCIRS) and the NDR workers as the study population would provide information on all radiation workers on a national basis. A work plan was prepared and some initial format conversion of historical data was undertaken to begin developing the NCIRS into a data base suitable for long-term health studies

    Global climate change is projected to increase the frequency and duration of periods of extremely high temperatures. Both the general populace and public health authorities often underestimate the impact of high temperatures on human health. To highlight the vulnerable populations and illustrate approaches to minimization of health impacts of extreme heat, the authors reviewed the studies of heat-related morbidity and mortality for high-risk populations in the U.S. and Europe from 1958 to 2012. Heat exposure not only can cause heat exhaustion and heat stroke but also can exacerbate a wide range of medical conditions. Vulnerable populations, such as older adults; children; outdoor laborers; some racial and ethnic subgroups (particularly those with low SES); people with chronic diseases; and those who are socially or geographically isolated, have increased morbidity and mortality during extreme heat. In addition to ambient temperature, heat-related health hazards are exacerbated by air pollution, high humidity, and lack of air-conditioning. Consequently, a comprehensive approach to minimize the health effects of extreme heat is required and must address educating the public of the risks and optimizing heatwave response plans, which include improving access to environmentally controlled public havens, adaptation of social services to address the challenges required during extreme heat, and consistent monitoring of morbidity and mortality during periods of extreme temperatures.

    Cardiovascular diseases (CVDs) are now in a rising trend in South East Asia including Myanmar due to increase in major cardiovascular risk factors in both urban and rural areas, such as smoking, obesity and diabetes mellitus. It is necessary to determine CVD morbidities in Myanmar for planning of prevention and control activities for CVDs. The cross-sectional household survey was conducted in 2012 with 600 people aged 40 years and above in four townships (Kyauk-Tan, Mawlamyaing, Pathein and Pyay) and used face-to-face interview with standard questionnaire [Rose Angina Questionnaire and Questionnaire by European Cardiovascular Indicators Surveillance Set (EUROCISS) Research Group] to determine the level of reported CVD morbidities in adult population. Age of the study population ranged from 40 to 99 years with the mean age of 56 years. Seventy-one percent of the study population was women. Nine percent of the study population have suffered from angina according to Rose Angina Questionnaire. Prevalence of possible heart attack, stroke and heart failure was 7.5, 1.5 and 2.8%. Prevalence of hypertension was 51%. The CVD morbidities are high. There is a need for strengthening prevention and control activities of CVDs.

    The shortage of available organs for transplantation is a worldwide issue. To maximize the number of transplantations, increasing the number of organs transplanted per donor (OTPD) is widely recognized as an important factor for improving the shortage. In Japan, we have had 211 donors, 1112 organs transplanted, and 924 recipients receiving the transplants, resulting in 4.4 ± 1.4 recipients receiving transplants per donor and 5.3 ± 1.6 OTPD as of February 2013. Because donor age is a well-recognized factor of donor suitability, we analyzed the correlation between donor age group and OTPD. Only the age group 60 to 69 years and the age group 70 to 79 years were significantly different (P donor under age 70 years has the potential to donate 4.6 to 6.7 organs.

    The value of the morbidity and mortality conference (M&MC) has received little examination in the primary care literature. We sought to understand the educational content of M&MCs by examining data from a family medicine training program. Archived morbidity and mortality conference data (July 2001-July 2003) were retrieved from two University of Michigan family medicine adult inpatient services (one community based and one university based). We used chi-square and t test to compare demographic variables and adverse events between hospital sites. We qualitatively analyzed written comments about adverse events. Both family medicine services shared similar diagnoses, patient volume, length of stay, and gender distribution of patients, but the community hospital had an older average patient age (67.9 years versus 52.9 years) and a higher outpatient complication rate. Analysis of the qualitative data revealed patterns of adverse events, such as an association between avoidable admissions and inadequate pain control, that could be improved through educational intervention. Although family medicine residents' experiences in university and community hospitals were comparable, there were differences in patient populations and case complexity. Modifying the M&MC format could enhance its effectiveness as an educational tool about adverse events.

    Full Text Available Painful radiculopathies (RAD and classical neuropathic pain syndromes (painful diabetic polyneuropathy, postherpetic neuralgia show differences how the patients express their sensory perceptions. Furthermore, several clinical trials with neuropathic pain medications failed in painful radiculopathy. Epidemiological and clinical data of 2094 patients with painful radiculopathy were collected within a cross sectional survey (painDETECT to describe demographic data and co-morbidities and to detect characteristic sensory abnormalities in patients with RAD and compare them with other neuropathic pain syndromes. Common co-morbidities in neuropathic pain (depression, sleep disturbance, anxiety do not differ considerably between the three conditions. Compared to other neuropathic pain syndromes touch-evoked allodynia and thermal hyperalgesia are relatively uncommon in RAD. One distinct sensory symptom pattern (sensory profile, i.e., severe painful attacks and pressure induced pain in combination with mild spontaneous pain, mild mechanical allodynia and thermal hyperalgesia, was found to be characteristic for RAD. Despite similarities in sensory symptoms there are two important differences between RAD and other neuropathic pain disorders: (1 The paucity of mechanical allodynia and thermal hyperalgesia might be explained by the fact that the site of the nerve lesion in RAD is often located proximal to the dorsal root ganglion. (2 The distinct sensory profile found in RAD might be explained by compression-induced ectopic discharges from a dorsal root and not necessarily by nerve damage. These differences in pathogenesis might explain why medications effective in DPN and PHN failed to demonstrate efficacy in RAD.

    To determine rising frequency of placenta previa and its associated morbidity in women with previous caesarean section. Study Design: Cross sectional study. Place and Duration of Study: This study was conducted in the Department of Obstetrics and Gynecology at CMH Kohat from Jul 2010 to Jun 2011. Patients and Methods: This study included all pregnant women undergoing repeat caesarean sections. Of these, total 74 patients were admitted with placenta previa. The frequency and associated morbidity were determined. Results: In our study 74 patients with placenta previa were included. 71.62% were less than 35 yrs of age, while 28.38% were equal to or more than 35 years. The gestational age at presentation was 24-36 weeks in 74.3% and 37 + weeks in 5.7% at presentation, 89% patients were symptomatic and 11% were asympyomatic. The morbidities observed were placenta accrete 47%, urinary tract trauma in 63.51%, caesarean hysterectomy in 62.16%, post operative febrile morbidity in 77.03%, maternal mortality was nil, paralytic ileus in 28.38%, PPH in 82.43%, surgical site infection in 16.21%. Conclusion: Frequency of placenta previa and its associated morbidity was raised due to repeated caesarean section rate which must be reduced to decrease maternal morbidity and mortality. (author)

    To analyze morbidity, in the context of a health area, and broken down by health centre, of patients who made contact with healthcare services, in order to propose an adjustment to finance the payment per capita. A descriptive study of morbidity observed in citizens assigned a health area during year 2010. SITE: Health Area 9. Autonomous Community of Madrid. Formed by the municipalities of Fuenlabrada, Humanes, and Moraleja de Enmedio. All levels of health care included. All citizens with health card assigned to a health center in the area who has maintained contact with the public health service's own area. Coded contact of patients are grouped using the Population Grouping Clinical Risk 3M TM Software (CRG). Each patient is included in a homogeneous and exclusive group with a numerical morbidity and clinical sense. Through the health card is known primary care centre, physician, age and sex. The distribution of morbidity is obtained by primary care centre, primary care physician, age and sex analyzing differences and combinations. It was found that the average values of the population morbidity are different in each primary care centre. In order to maintain the principle of equity in health care, it is suggested that an adjustment is made to the per capita payment based on the morbidity rate of the population.

    To assess short term morbidity and renal function after robotic laparoscopic living donor nephrectomy. We performed a retrospective analysis of 100 consecutives patients undergoing a robotic laparoscopic living donors nephrectomy. We analyzed isotopic measure of the renal function before and 4 months after surgery, the side, the number of arteries, the blood loss, the operative time and warm ischemia time. In the outcomes, we collected the complications, the length of stay, and for the receiver, the renal function recovery time, dialysis, survival and renal function at one year. Left kidney nephrectomy was performed in 85 patients and we observed 25 multiples renal arteries. Mean estimated blood loss was 0,8 g/dL. Mean operative time and warm ischemia time were respectively 174 ± 30 and 4.8 ± 1.7 minutes. Seven complications occured, with 2 major (Clavien-Dindo System). Mean length of stay was 5.1 ± 1.9 days. Mean glomerular filtration decrease was 26% and remains stable at one year after surgery. Grafts had an immediate renal function recovery for 99%, and were all functional after one year, with mean MDRD clearance of 57 ± 14mL/min. Robotic procedure in laparoscopic living donor nephrectomy seems to guarantee low morbidity and the stability of the renal function decrease of 26%. Copyright © 2013.

    We present the detailed study of the spin kinetics of the nitrogen (N) donor electrons in 6H SiC wafers grown by the Lely method and by the sublimation "sandwich method" (SSM) with a donor concentration of about 1017 cm-3 at T = 10-40 K. The donor electrons of the N donors substituting quasi-cubic "k1" and "k2" sites (Nk1,k2) in both types of the samples revealed the similar temperature dependence of the spin-lattice relaxation rate (T1-1), which was described by the direct one-phonon and two-phonon processes induced by the acoustic phonons proportional to T and to T9, respectively. The character of the temperature dependence of the T1-1 for the donor electrons of N substituting hexagonal ("h") site (Nh) in both types of 6H SiC samples indicates that the donor electrons relax through the fast-relaxing centers by means of the cross-relaxation process. The observed enhancement of the phase memory relaxation rate (Tm-1) with the temperature increase for the Nh donors in both types of the samples, as well as for the Nk1,k2 donors in Lely grown 6H SiC, was explained by the growth of the free electron concentration with the temperature increase and their exchange scattering at the N donor centers. The observed significant shortening of the phase memory relaxation time Tm for the Nk1,k2 donors in the SSM grown sample with the temperature lowering is caused by hopping motion of the electrons between the occupied and unoccupied states of the N donors at Nh and Nk1,k2 sites. The impact of the N donor pairs, triads, distant donor pairs formed in n-type 6H SiC wafers on the spin relaxation times was discussed.

    Full Text Available BACKGROUND: The association between obesity in adults and excess morbidity and mortality is well established, but the health impact throughout adult life of being obese in early adulthood needs elucidation. We investigated somatic morbidity, including fatal morbidity, throughout adulthood in men starting adult life as obese. METHODS: Among 362,200 Danish young men, examined for military service between 1943 and 1977, all obese (defined as BMI≥31.0 kg/m(2, and, as controls, a random 1% sample of the others was identified. In the age range of 18-25 years, there were 1,862 obese, which encompass the men above the 99.5 percentile, and 3,476 controls. Information on morbidity was obtained via national registers. Cox regression models were used to estimate the relative morbidity assessed as first incidence of disease, occurrence of disease in the year preceding death and prevalent disease at time of death. RESULTS: From age 18 through 80 years the obese had an increased risk of becoming diseased by or die from a broad range of diseases. Generally, the incidence of first event, occurrence in the year prior to death, and prevalence at time of death showed the same pattern. As an example, the relative hazard of type 2 diabetes was constant throughout life at 4.9 (95% confidence intervals [CI]: 4.1-5.9, 5.2 (95% CI: 3.6-7.5, and 6.8 (95% CI: 4.6-10.1, respectively. CONCLUSIONS: Our findings strongly support the continued need to avoid beginning adult life as obese, as obese young men experience an increased morbidity, including fatal morbidity, from many diseases throughout life.

  9. The impact of disclosure on donor gamete participants: donors, intended parents and offspring.

    2008-06-01

    The present review examines recent publications that provide insight into how the trend toward nonanonymity and disclosure in gamete donation impacts donors, intended parents, and their donor-conceived children. Recent findings show an increase in donor programs that offer open-identity between donors and offspring. The psychological needs of gamete donors and their attitudes toward disclosure are increasingly given consideration. Qualitative research on how parents of donor gamete offspring make decisions about disclosure reveals that even when couples initially disagree about disclosing to offspring, most ultimately come to a united disclosure decision. The literature on the impact of disclosure on donor gamete offspring has extended to include children conceived through embryo donation and children born as a result of surrogacy. The absence of genetic or gestational link between parents and their child does not have a negative impact on parent-child relationships. Parents through surrogacy tend to disclose the method of family creation to their child, whereas parents through embryo donation tend to be secretive about their child's origins. The trend toward greater openness in gamete donation has been accompanied by an increase in programs offering open-identity donation. In addition, the psychological needs of gamete donors and their attitudes toward disclosure are increasingly being given consideration. Parents of donor gamete offspring give careful thought to their disclosure decisions, and the psychological well being of donor-conceived children does not seem to be impacted by those decisions.

    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.

    Online crowdfunding platforms like DonorsChoose.org and Kick-starter allow specific projects to get funded by targeted contributions from a large number of people. Critical for the success of crowdfunding communities is recruitment and continued engagement of donors. With donor attrition rates above 70%, a significant challenge for online crowdfunding platforms as well as traditional offline non-profit organizations is the problem of donor retention. We present a large-scale study of millions of donors and donations on DonorsChoose.org, a crowdfunding platform for education projects. Studying an online crowdfunding platform allows for an unprecedented detailed view of how people direct their donations. We explore various factors impacting donor retention which allows us to identify different groups of donors and quantify their propensity to return for subsequent donations. We find that donors are more likely to return if they had a positive interaction with the receiver of the donation. We also show that this includes appropriate and timely recognition of their support as well as detailed communication of their impact. Finally, we discuss how our findings could inform steps to improve donor retention in crowdfunding communities and non-profit organizations.

    Pre-existing donor-specific HLA antibodies in patients undergoing HLA-mismatched SCT have increasingly been recognized as a risk factor for primary graft failure. However, the clinical implications of the presence of HLA antibodies in donors remain unknown. We prospectively examined 123 related donors for the presence of HLA antibodies by using a Luminex-based single antigen assay. Of these, 1/57 (1.8%) male, 6/27 (22%) parous female and 0/39 (0%) nonparous female donors were HLA antibody-positive. Then, we determined the presence of HLA antibodies in seven patients who received SCT from antibody-positive donors. Of these, four became HLA antibody-positive after SCT. The specificities of the antibodies that emerged in the patients closely resembled those of the antibodies found in the donors, indicating their production by donor-derived plasma cells. Moreover, the kinetics of the HLA antibody levels were similar in all four patients: levels started increasing within 1 week after SCT and peaked at days 10-21, followed by a gradual decrease. These results suggest that donor-derived HLA antibody production frequently occurs in patients undergoing SCT from antibody-positive donors. Further studies are warranted for clarifying the clinical significance of donor-derived HLA antibodies, including the role of these antibodies in post transplant platelet transfusion refractoriness.

    1986-01-01

    Following administration of haploidentical stem cells to infants with severe combined immunodeficiency (SCID), mature T cells of donor karyotype appear later in the recipient without causing graft-versus-host disease. To investigate the effect of the host environment on the responsiveness of these genetically donor T cells, blood B and T lymphocytes from 6 SCID recipients, their parental donors and unrelated controls were purified by double SRBC rosetting. T cells were stimulated by irradiated B cells at a 1:1 ratio in 6 day cultures. Engrafted T cells of donor karyotype gave much smaller responses to irradiated genetically recipient B cells than did fresh donor T cells. Moreover, engrafted T cells of donor karyotype from two of the three SCIDs who are longest post-transplantation responded more vigorously (14,685 and 31,623 cpm) than fresh donor T cells (5141 and 22,709 cpm) to donor B cells. These data indicate that T lymphocytes which have matured from donor stem cells in the recipient microenvironment behave differently from those that have matured in the donor

    2015-10-01

    There is a lack of knowledge about sibling stem cell donors' experiences pre-donation and the waiting period before the donation might have been long. The donors and their corresponding sibling recipients were simultaneously included in two different interview studies. The results from the recipient study have been presented in a separate paper. The aim was to explore the experiences of being a stem cell donor for a sibling, prior to donation. Ten adult sibling donors were interviewed prior to stem cell donation. The interviews were digitally recorded, transcribed verbatim and subjected to qualitative content analysis. The main theme Being a cog in a big wheel describes the complex process of being a sibling donor prior to donation, covering a mixture of emotions and thoughts. The four subthemes Being available, Being anxious, Being concerned and Being obliged cover the various experiences. The sibling donors' experiences are influenced by the quality of the relationship with the sick sibling. Sibling stem cell donors go through a complex process once they have accidentally got involved in. They have been asked to become a donor; it was not a voluntary choice. In caring for sibling stem cell donors the nurses should be aware of the complexity of the process they experience and take into consideration their personal situation and needs. Providing optimal care for both sibling donors and their corresponding recipients is a challenge, and further improvement and exploration are needed. Copyright © 2015 Elsevier Ltd.

    1993-01-01

    Photothermal ionization spectroscopy on neutron-irradiated and subsequently hydrogen-plasma-treated silicon reveals the existence of new shallow donors. The binding energies of the observed effective-mass-like donors are between 34 and 53 meV. The optical dipole transitions of the different donors are shifted towards higher energies by ΔE=0.1--0.2 cm -1 , when deuterium is used in the plasma instead of hydrogen. This isotope shift of the optical dipole transitions between the electronic levels of the defects is direct proof of the incorporation of hydrogen in these defects

    2008-01-01

    The present paper examines the macroeconomic impact of aid, by introducing endogenous aid allocations into a neoclassical growth framework. On this basis it is shown that donor policies can have important implications for the trajectory of recipients' GDP per capita. Depending on specific donor...... policy choices, aid disbursements may lead to faster transitional growth, stagnation or cyclical growth. Moreover, the analysis also suggests that donor policies may be part of the reason why foreign aid is not found to be uniformly effective in raising long-run productivity across recipients...

  17. Kidney for sale by live donor.

    Brahams, D

    1989-02-04

    The capacity to consent to bodily harm is explored in relation to the trade in kidneys obtained from impoverished healthy live donors for cash. The British medical profession has unambiguously condemned the practice, but the law in Britain allows a donor to consent to serious injury where the act had some social purpose, recognized by the law as valid. Allegations against the private Humana Hospital Wellington that indigent Turks were brought to Britain to be paid kidney donors, and similar practices elsewhere, are discussed. Questions are raised about the illegality of such contracts in Britain and the possibility of a Parliamentary Act making brokerage and involvement with such cash transactions a criminal offense.

  18. Human decellularized bone scaffolds from aged donors show improved osteoinductive capacity compared to young donor bone.

    Directory of Open Access Journals (Sweden)

    Christopher A Smith

    Full Text Available To improve the safe use of allograft bone, decellularization techniques may be utilized to produce acellular scaffolds. Such scaffolds should retain their innate biological and biomechanical capacity and support mesenchymal stem cell (MSC osteogenic differentiation. However, as allograft bone is derived from a wide age-range, this study aimed to determine whether donor age impacts on the ability an osteoinductive, acellular scaffold produced from human bone to promote the osteogenic differentiation of bone marrow MSCs (BM-MSC. BM-MSCs from young and old donors were seeded on acellular bone cubes from young and old donors undergoing osteoarthritis related hip surgery. All combinations resulted in increased osteogenic gene expression, and alkaline phosphatase (ALP enzyme activity, however BM-MSCs cultured on old donor bone displayed the largest increases. BM-MSCs cultured in old donor bone conditioned media also displayed higher osteogenic gene expression and ALP activity than those exposed to young donor bone conditioned media. ELISA and Luminex analysis of conditioned media demonstrated similar levels of bioactive factors between age groups; however, IGF binding protein 1 (IGFBP1 concentration was significantly higher in young donor samples. Additionally, structural analysis of old donor bone indicated an increased porosity compared to young donor bone. These results demonstrate the ability of a decellularized scaffold produced from young and old donors to support osteogenic differentiation of cells from young and old donors. Significantly, the older donor bone produced greater osteogenic differentiation which may be related to reduced IGFBP1 bioavailability and increased porosity, potentially explaining the excellent clinical results seen with the use of allograft from aged donors.

  19. On harm thresholds and living organ donation: must the living donor benefit, on balance, from his donation?

    Science.gov (United States)

    Williams, Nicola Jane

    2018-03-01

    For the majority of scholars concerned with the ethics of living organ donation, inflicting moderate harms on competent volunteers in order to save the lives or increase the life chances of others is held to be justifiable provided certain conditions are met. These conditions tend to include one, or more commonly, some combination of the following: (1) The living donor provides valid consent to donation. (2) Living donation produces an overall positive balance of harm-benefit for donors and recipients which cannot be obtained in a less harmful manner. (3) Donation is not liable to cause significant and long-term morbidity to, or the death of, the donor. This paper critically examines the suggestion that these criteria are not sufficient to offer a general account of justified living organ donation in the context of competent volunteers and that key to justified living organ donation is that donors receive sufficient benefits from their donation that these outweigh the harms they suffer. However, although this view-termed here 'The Donor Benefit Standard'-directs welcome attention to the many and complex motives which may underlie living organ donation, this paper ultimately concludes that given the threats this position poses to individual autonomy and the lives of those in need of organ transplants 'The Donor Benefit Standard' should ultimately be rejected.

    Full Text Available Introduction: This study aimed to estimate the proportion of patients with Interstitial Cystitis/Painful Bladder Syndrome (IC/BPS with systemic dysfunction associated co-morbidities such as irritable bowel syndrome (IBS and fibromyalgia (FM. Material and Methods: Two groups of subjects with IC/BPS were included: 1 Physician diagnosed patients with IC/BPS and 2 Subjects meeting NIDDK IC/PBS criteria based on a questionnaire (ODYSA. These groups were compared to healthy controls matched for age and socio-economic status. NIDDK criteria required: pain with bladder filling that improves with emptying, urinary urgency due to discomfort or pain, polyuria > 11 times/24 hrs, and nocturia > 2 times/night. The ODYSA instrument evaluates symptoms pertaining to a range of disorders including chronic fatigue, orthostatic intolerance, syncope, IBS, dyspepsia, cyclic vomiting syndrome, headaches and migraines, sleep, Raynaud’s syndrome and chronic aches and pains. Results: IC/BPS was diagnosed in 26 subjects (mean age 47 +/- 16 yrs, 92% females, 58 had symptoms of IC/BPS by NIDDK criteria, (mean age 40 +/- 17 yrs, 79% females and 48 were healthy controls (mean age 31+/- 14 yrs, mean age 77%. Co-morbid complaints in the IC/BPS groups included gastrointestinal symptoms suggestive of IBS and dyspepsia, sleep abnormalities with delayed onset of sleep, feeling poorly refreshed in the morning, waking up before needed, snoring, severe chronic fatigue and chronic generalized pain, migraines and syncope. Discussion: Patients with IC/BPS had co-morbid central and autonomic nervous system disorders. Our findings mirror those of others in regard to IBS, symptoms suggestive of FM, chronic pain and migraine. High rates of syncope and functional dyspepsia found in the IC/BPS groups merit further study to determine if IC/BPS is part of a diffuse disorder of central, autonomic and sensory processing affecting multiple organs outside the bladder.

    Waiting lists for kidney transplantation continue to grow and live organ donation has become more important as the number of brain stem dead cadaveric organ donors continues to fall. The major disincentive to potential kidney donors is the pain and morbidity associated with open surgery. To identify the benefits and harms of using laparoscopic compared to open nephrectomy techniques to recover kidneys from live organ donors. We searched the online databases CENTRAL (in The Cochrane Library 2010, Issue 2), MEDLINE (January 1966 to January 2010) and EMBASE (January 1980 to January 2010) and handsearched textbooks and reference lists. Randomised controlled trials comparing laparoscopic donor nephrectomy (LDN) with open donor nephrectomy (ODN). Two review authors independently screened titles and abstracts for eligibility, assessed study quality, and extracted data. We contacted study authors for additional information where necessary. Six studies were identified that randomised 596 live kidney donors to either LDN or ODN arms. All studies were assessed as having low or unclear risk of bias for selection bias, allocation bias, incomplete outcome data and selective reporting bias. Four of six studies had high risk of bias for blinding. Various different combinations of techniques were used in each study, resulting in heterogeneity in the results. The conversion rate from LDN to ODN ranged from 1% to 1.8%. LDN was generally found to be associated with reduced analgesia use, shorter hospital stay, and faster return to normal physical functioning. The extracted kidney was exposed to longer warm ischaemia periods (2 to 17 minutes) with no associated short-term consequences. ODN was associated with shorter duration of procedure. For those outcomes that could be meta-analysed there were no significant differences between LDN or ODN for perioperative complications (RR 0.87, 95% CI 0.47 to 4.59), reoperations (RR 0.57, 95% CI 0.09 to 3.64), early graft loss (RR 0.31, 95% CI 0

    Full Text Available Background. De novo and donor-derived invasive fungal infections (IFIs contribute to morbidity and mortality in solid organ transplant (SOT recipients. Reporting of donor-derived IFIs (DDIFIs to the Organ Procurement Transplant Network has been mandated since 2005. Prior to that time no systematic monitoring of DDIFIs occurred in the United States. Case Presentation. We report a case of primary graft dysfunction in a 49-year-old male lung transplant recipient with diffuse patchy bilateral infiltrates likely related to pulmonary Sporothrix schenckii infection. The organism was isolated from a bronchoalveolar lavage on the second day after transplantation. Clinical and radiographic responses occurred after initiation of amphotericin B lipid formulation. Conclusion. We believe that this was likely a donor-derived infection given the early timing of the Sporothrix isolation after transplant in a bilateral single lung transplant recipient. This is the first case report of sporotrichosis in a lung transplant recipient. Our patient responded well to amphotericin induction therapy followed by maintenance therapy with itraconazole. The implications of donor-derived fungal infections and Sporothrix in transplant recipients are reviewed. Early recognition and management of these fungi are essential in improving outcomes.

    Solid organ demand far exceeds organ supply. Strategies to increase the donor pool include the liberalization of selection criteria without increasing the risk of unexpected donor-derived infection (DDI), a rare complication of transplantation carrying high morbidity and mortality. We review the challenging aspects in the prevention of DDI, focusing on the complexities of data sharing and efficient communication and the role infectious diseases specialists play in the process. Advances in donor screening, transmission recognition and reporting allow for a better estimation of the risk of DDI. However, there is great variability in the frequency and methods with which organ procurement organizations report transmission events.Moreover, the Scientific Registry of Transplant Recipients provides limited donor and recipient outcome infectious diseases related data. Infectious disease contribution to the allocation process has been found to improve organ donation efficiency and communication between involved parties. Although communication gaps are strongly associated with infection transmission (relative risk 2.36%, confidence interval 1.48-3.78), effective communication minimizes or prevents infection in transplant recipients (X(1) 13.13, P = 0.0003). Prospective research is still required to define optimal screening protocols and further prevent transmission of infection. A holistic approach is likely to result in enhanced transplantation safety. Toward this goal, development of standards of investigation; improvement in reporting and data sharing; and strategies ensuring coordinated and rapid communication among parties involved in the allocation process need to be pursued.

    A tenet of microeconomics is that new technology will shift the supply curve to the right. Laparoscopic donor nephrectomy (LDN) is a new technique for removal of living donor kidneys. Centers performing this procedure have noted an increased number of patients presenting for donor evaluation. This has not been previously studied. The records of all LDN performed from May 1998 to February 1999 were reviewed. The following variables were examined: sex, age, related vs. unrelated donation, estimated blood loss, i.v. analgesia, length of stay, and time out of work. Donors undergoing traditional open donor nephrectomy during January 1997 to May 1998 served as the control group. A composite cost index was constructed. LDN significantly decreased length of stay, pain, and time out of work; the supply function shifted to the right. Telephone interviews revealed that 47% donated solely because of the LDN procedure. LDN increases the supply of living donor kidneys.

  10. Donor-Derived Myeloid Sarcoma in Two Kidney Transplant Recipients from a Single Donor

    Full Text Available We report the rare occurrence of donor-derived myeloid sarcoma in two kidney transplant patients who received organs from a single deceased donor. There was no evidence of preexisting hematologic malignancy in the donor at the time of organ recovery. Both recipients developed leukemic involvement that appeared to be limited to the transplanted organ. Fluorescence in situ hybridization (FISH and molecular genotyping analyses confirmed that the malignant cells were of donor origin in each patient. Allograft nephrectomy and immediate withdrawal of immunosuppression were performed in both cases; systemic chemotherapy was subsequently administered to one patient. Both recipients were in remission at least one year following the diagnosis of donor-derived myeloid sarcoma. These cases suggest that restoration of the immune system after withdrawal of immunosuppressive therapy and allograft nephrectomy may be sufficient to control HLA-mismatched donor-derived myeloid sarcoma without systemic involvement.

    We sought to determine the deceased donor factors associated with outcome after kidney transplantation and to develop a clinically applicable Kidney Donor Risk Index. Data from the UK Transplant Registry on 7620 adult recipients of adult deceased donor kidney transplants between 2000 and 2007 inclusive were analyzed. Donor factors potentially influencing transplant outcome were investigated using Cox regression, adjusting for significant recipient and transplant factors. A United Kingdom Kidney Donor Risk Index was derived from the model and validated. Donor age was the most significant factor predicting poor transplant outcome (hazard ratio for 18-39 and 60+ years relative to 40-59 years was 0.78 and 1.49, respectively, Pinformed consent.

    For people with end-stage kidney disease, a transplant is the promise of a future without dialysis. Living donor kidney transplantation comprises many specificities and is distinct from cadaveric donor transplantation. Some psychological aspects explain these specificities. They may be subconscious and difficult to access, but it is essential to decipher them in order to adapt the support provided to these people. Copyright © 2016 Elsevier Masson SAS.

    High altitude, often characterized by settings over 2400m, can be detrimental to the human body and pose a significant risk to ocular health. Reports concerning various ocular morbidities occurring as a consequence of high altitude are limited in the current literature. This study was aimed at evaluating the ocular health of porters working at high altitudesof Himalayas in Nepal. A mobile eye clinic was set up in Ghat and patient data were collected from its out- patient unit by a team of seven optometrists which was run for five days. Ghat is a small village in north-eastern Nepal, located at 2860 m altitude. Travellers walking through the trekking route were invited to get their eyes checked at the clinic. Comprehensive ocular examinations were performed, including visual acuities, objective and subjective refraction, anterior and posterior segment evaluations, and intraocular pressure measurements; blood pressure and blood glucose levels were also measured as required. Ocular therapeutics, prescription glasses, sunglasses and ocular health referrals were provided free of cost as necessary. A total of 1890 people visited the eye clinic, among which 57.4% (n=1084) were porters. Almost half of the porters had an ocular morbidity. Correctable refractive error was most prevalent, with other ocular health-related complications, including dry eye disease, infectious disorders, glaucoma and cataract. Proper provision of regular and effective eye care services should be made more available for those residing at these high altitudes in Nepal. © NEPjOPH.

In a cross-sectional study of 174 girls, height, weight, waist circumference, Tanner stage, reproductive hormones, carbohydrate and lipid markers, drug use, and menstrual history were obtained at baseline. Exclusion criteria were menarcheal age PCOS or MeS classification. University medical center outpatient clinic. Ninety-eight girls ages 13-19.6 years, Tanner 5, average body mass index of 46.6 kg/m(2), menarche at 11.4 years, and average menarcheal age of 5 years. None. Polycystic ovary syndrome and MeS. Ninety-eight girls were divided into four groups: PCOS by National Institutes of Health criteria (PCOSN, n = 24), irregular menses only (n = 25), elevated T (≥55 ng/dL) only (n = 6), and obese controls (n = 43). Metabolic syndrome by modified Cook criteria affected 32 girls or 33% overall: 6 of 24 PCOSN, 7 of 25 irregular menses only, 4 of 6 elevated T only, and 15 of 43 obese controls. Polycystic ovary syndrome by National Institutes of Health criteria and its individual components were not associated with MeS after adjusting for body mass index. Unlike obese adults, PCOSN and its individual components were not associated with MeS in the untreated morbidly obese adolescent population.

    Transplant medicine's impact on America's public health is seriously limited by acute shortage of transplantable organs. Consequently, the United Sates has witnessed considerable investment in the promotion of organ donor registries. Although there is no evidence to support that donor registry promotion alleviates organ shortage, this belief continues to drive investments into registry promotion. In this study, return on investment in donor registry promotion was examined using cost-outcomes analysis. Cost of promoting the donor registry was estimated in US dollars whereas the outcome was measured as the number of individuals who join the registry (registrants) and their value in terms of organ donors. The study was conducted from the perspective of a regional Organ Procurement Organization (OPO). Costs were directly obtained from the OPO. The number of new registrants was obtained from the OPO and the departments of motor vehicles that maintain the donor registry. The value of registrants in terms of organ donors was computed based on a registrant's age-dependent risk of dying and age-dependent probability of becoming an organ donor. Six thousand seven hundred eight individuals joined the organ donor registry (95% confidence interval [95% CI], 5429-7956) at a cost of $455 per registrant (95% CI, US $383-US $562). These individuals result in 4.2 present-day donors (95% CI, 2.5-6.6) at a cost of US $726 000 (95% CI, US $462000-US $1.2 million). Because the cost per registrant and cost per donor is less than society's willingness to pay, donor registry promotion offers positive return on investment. Investment in registry promotion should at the minimum be maintained at current levels.

    This article considers the disclosure, sharing and exchange of information on being donor conceived within families, drawing on data from a study undertaken with donor-conceived adults registered with UK Donor Link (a voluntary DNA-linking register). This paper considers the narratives of how respondents found out they were donor-conceived and what events triggered disclosure of this information. This paper then goes on to examine the role secrecy played in their family life and uses the concept of 'display' to explore how secrecy affected their relationships with their immediate and extended family. Secrets are notoriously 'leaky' and we found complex patterns of knowing and uncertainty about whom in the family knew that the person was donor-conceived. We argue that what is kept secret and from whom provides insights into the multifaceted web of social relationships that can be created by donor-conception, and how knowledge can be managed and controlled in attempts to display and maintain family narratives of biogenetic connection. © 2017 Foundation for the Sociology of Health & Illness.

    Over the last two decades, lung transplantation emerged as the standard of care for patients with advanced and terminal lung disease. Despite the increment in lung transplantation rates, in 2016 the overall mortality while on waiting list in Italy reached 10%, whereas only 39% of the wait-list patients were successfully transplanted. A number of approaches, including protective ventilatory strategy, accurate management of fluid balance, and administration of a hormonal resuscitation therapy, have been reported to improve lung donor performance before organ retrieval. These approaches, in conjunction with the use of ex-vivo lung perfusion technique contributed to expand the lung donor pool, without affecting the harvest of other organs and the outcomes of lung recipients. However, the efficacy of issues related to the ex-vivo lung perfusion technique, such as the optimal ventilation strategy, the ischemia-reperfusion induced lung injury management, the prophylaxis of germs transmission from donor to recipient and the application of targeted pharmacologic therapies to treat specific donor lung injuries are still to be explored. The main objective of the present review is to summarize the "state-of-art" strategies to optimize the donor lungs and to present the actual role of ex-vivo lung perfusion in the process of lung transplant. Moreover, different approaches about the technique reported in literature and several issues that are under investigation to treat specific donor lung injury will be discussed.

    In the context of living donor liver transplantation (LDLT), German transplantation law stipulates that donor candidates should primarily be relatives of the recipients or persons with distinct and close relationships. In this study, we investigated the influence of the relationship between the donor and the recipient on the donor's emotional strain before transplantation. Donors were categorized according to the following subgroups: (1) parents donating for their children, (2) children donating for their parents, (3) siblings, (4) spouses, (5) other relatives, and (6) nonrelatives. The sample consisted of 168 donor candidates. Anxiety (F = 2.8, P = 0.02), depression (F = 2.6, P = 0.03), and emotional quality of life (F = 3.1, P = 0.01) differed significantly according to the relationship between the donor and the recipient. In comparison with healthy controls, parents donating for their children were significantly less stressed before LDLT and demonstrated fewer anxiety (P depression symptoms (P < 0.05). Adult children donating for their parents demonstrated the highest mental burden and the lowest emotional quality of life. However, this was not due to the responsibility of these children for their own families because differences between donors with children and donors without children could not be ascertained. This group should be given special attention before LDLT and during follow-up visits, and psychological help should be provided when it is necessary.

    Morbid obesity (MO) has become an epidemic in the United Sates and is associated with adverse effects on health. The purpose of this study was to examine the effects of MO on the short-term outcomes of kidneys transplanted from donation after cardiac death (DCD) donors. Using a prospectively collected database, we reviewed 467 kidney transplantations performed at a single center between January 2008 and June 2011 to identify 67 recipients who received transplants from 40 DCD donors. The outcomes of 14 MO DCD donor kidneys were compared with 53 non-MO DCD grafts. MO was defined as a body mass index ≥ 35. Mean patient follow-up was 16 months. The MO and non-MO DCD donor groups were similar with respect to donor and recipient age, gender, race, cause of death and renal disease, time from withdrawal of life support to organ perfusion, mean human leukocyte antigen (HLA) mismatch, and overall recipient survival. Organs from MO DCD donors also had comparable rates of delayed graft function (21.4% vs 20.0%; P = not significant [NS]). At 1 year post-transplantation, a small but statistically insignificant difference was observed in the graft survival rates of MO and non-MO donors (87% vs. 96%; P = NS). One MO kidney had primary nonfunction. These data demonstrate that kidneys procured from MO DCD donors have equivalent short-term outcomes compared with non-MO grafts and should continue to be used. Further investigation is needed to examine the effect of MO on long-term renal allograft survival. Copyright © 2014 Elsevier Inc. All rights reserved.

    We examined the association between kleptomania and addictive disorders, including behavioral addictions. Fifty-three individuals with a diagnosis of kleptomania completed measures of kleptomania severity, semi-structured clinical interviews to assess co-morbid diagnosis of addictive disorders, and the Shorter PROMIS Questionnaire (SPQ) assessing an array of addictive behaviors. 20.75% of the sample met criteria for an addictive disorder; four for a substance use disorder and four for a behavioral addiction. Kleptomania severity was significantly associated with compulsive work and shopping measured by the SPQ. The results suggest the need to assess a wide array of addictive behaviors in individuals with kleptomania. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

    Obesity has been associated with increased risk for postoperative CSF leak in patients with benign cranial nerve tumors. Other measures of postoperative morbidity associated with obesity have not been well characterized. Patients enrolled in the American College of Surgeons' National Surgical Quality Improvement Program (ACS-NSQIP) from 2007 to 2013 with a diagnosis code of a benign neoplasm of a cranial nerve were included. The primary outcome of postoperative morbidity was analyzed as well as secondary outcomes of readmission and reoperation. The main covariate of interest was body mass index (BMI). A total of 561 patients underwent surgery for a benign cranial nerve neoplasm between 2007 and 2013. Readmission data, available for 2012-2013(n=353), revealed hydrocephalus, facial nerve injury, or CSF leak requiring readmission or reoperation occurred in 0.85%, 1.42%, and 3.12%, respectively. Composite morbidity included wound complications, infection, respiratory insufficiency, transfusion requirement, stroke, venous thromboembolism, coma and cardiac arrest. On multivariable analysis patients with class I (BMI 30-34.9) and II (BMI 35-39.9) obesity showed trends towards increasing return to operating room, though not significant, but there was no trend for composite complications in class I and II obesity patients. However, class III obesity, BMI≥40, was associated with increased odds of composite morbidity (OR 4.40, 95% CI 1.24-15.88) and return to the operating room (OR 5.97, 95% CI 1.20-29.6) relative to patients with a normal BMI, 18.5-25. Obesity is an independent and important risk factor for composite morbidity in resection of benign cranial nerve neoplasms, and as such, merits discussion during preoperative counseling.

    Background: Obstetric hysterectomy still complicates a substantial number of pregnancies in third world countries and is a significant cause of obstetric morbidity and mortality. This study was carried out to evaluate in our setup the frequency of obstetric hysterectomy, its indication, risk factors, complication, morbidity, mortality and avoidable factors. Methods: A descriptive study of all patients who under went obstetric hysterectomy was conducted from May 1, 2004 to October 31, 2005 at Gynaecology and Obstetric Unit-II, III of Liaquat University of Medical and Health Science Hospital, Hyderabad. After collecting the data on pre-designed proforma the data was fed to SPSS in the form of frequency distribution tables and percentages were calculated. Statistical analysis of data was performed by using Chi-square test. The level of significance was taken as p<0.05. Results: During the study time period there were total 6495 deliveries and 41 cases of obstetric hysterectomy were identified, giving a frequency of 0.63% or 1 in 158 deliveries. Most of patients were from rural areas (82.92%), un-booked 73.17%), uneducated (95%), lower socio economical class (92.69%), 25-29 years age (48.78%) multiparae (56.10%), have to travel a distance of <100 km to reach hospital and referred late (51%) by health care providers (doctors). Majority of hysterectomies were performed due to ruptured uteri (51.21%). There were 5 maternal and 26 perinatal deaths; all were due to severity of conditions necessitating hysterectomy. Conclusion: Incidence of obstetric hysterectomy in our woman is very high. The reason being many avoidable factors such as high parity, inadequate maternity and family planning services, lack of proper referral system, un-booked status, mismanaged labour, illiteracy on the part of woman herself, family and health care providers are not taken care of during pregnancy, labour and puerperium.

    BACKGROUND: Pediatric-onset multiple sclerosis (MS) affects life at a stage vital for social and educational achievements and psychiatric co-morbidity is common after MS onset. Few studies have examined psychiatric morbidity before MS onset. METHODS: In this nationwide study, detailed case...... with psychiatric morbidity as exposure and MS as outcome, and a matched cohort study with MS as exposure and psychiatric co-morbidity as outcome. Hazard ratios (HR) including 95% confidence intervals (CI) were estimated using Cox regression. RESULTS: We identified 212 children with MS and 1060 controls....... No association between psychiatric morbidity and the rate of MS was found before MS onset. After MS onset, children with MS had two times higher hazard for psychiatric co-morbidity compared with children without MS (HR=2.0; 95% CI=1.3-3.1; pPsychiatric morbidity seems to commence after MS...

    Aims and Objective: (1) To study the age and sex distribution of patient with oral malignancies. (2) To analyze various types of surgery performed. (3) Evaluation of reconstruction and factors affecting complications and its relation to the type of reconstruction. Materials and Methods: Cases of oral malignancies, undergoing surgery for the same in Sri Aurobindo Medical College and PG Institute, Indore from the period from October 1, 2012, to March 31, 2015. Results: Out of analysis of 111 cases of oral malignancy, 31 (27.9%) cases were in the fifth decade of life with male to female ratio 1.9:1. The commonest site of cancer was buccal mucosa. Forty-seven cases (43.2%) were in stage IVa. Diabetes was the most common co-morbidity reported, accounting for 53.9% of cases with reported morbidity. Tobacco chewing was the common entity in personal habits. All the cases underwent neck dissection along with resection of the primary. Hemimandibulectomy was the most preferred form of primary resection accounting for 53.15% (59 cases), followed by wide resection of primary 27% (30 cases). Pectoralis major myocutaneous (PMMC) flap only was the most common reconstruction across the study population. PMMC alone accounted for 38.7% (43 cases). The infection rate was 16.21%. PMMC alone accounted for 5 out of 18 (27.8%) of total infection rate, and 4.5% of the total study population. PMMC + deltopectoral accounted for 5 out of 18 (27.8%) of total infection rate, and 4.5% of the total study population. Conclusion: PMMC is a major workhorse for reconstruction with better functional outcome and acceptance among operated patients. PMID:26981469

    This paper reports on a study of the views and experiences of 21 sperm donors and five egg donors registered with UK DonorLink (UKDL), a voluntary DNA-based contact register established to facilitate contact between adults who wish to identify and locate others to whom they are genetically related following donor conception. Specifically, the paper examines donors' reasons for searching for, or making information about themselves available to donor-conceived offspring. Their expectations of registration with UKDL, experiences of being registered and finally, the experiences of those who had contacted donor-conceived offspring and other genetic relatives are investigated. While most respondents reported largely positive experiences of registration, the study found significant issues relating to concerns about donation, DNA testing, possible linking with offspring and expectations of any relationship that might be established with offspring that have implications for support, mediation and counselling. Research that puts the experiences, perceptions and interests of gamete donors as the central focus of study is a relatively recent phenomenon. This study contributes to this debate and highlights directions for future research in this area.

    Oocyte donation is an efficient alternative to using own oocytes in IVF treatment for different indications. Unfortunately, 'traditional' (fresh) egg donations are challenged with inefficiency, difficulties of synchronization, very long waiting periods and lack of quarantine measures. Given the recent improvements in the efficiency of oocyte cryopreservation, it is reasonable to examine if egg donation through oocyte cryopreservation has merits. The objective of the current manuscript is to review existing literature on this topic and to report on the most recent outcomes from two established donor cryobank centres. Reports on egg donation using slow freezing are scarce and though results are encouraging, outcomes are not yet comparable to a fresh egg donation treatment. Vitrification on the other hand appears to provide high survival rates (90%) of donor oocytes and comparable fertilization, embryo development, implantation and pregnancy rates to traditional (fresh) egg donation. Besides the excellent outcomes, the ease of use for both donors and recipients, higher efficiency, lower cost and avoiding the problem of synchronization are all features associated with the benefit of a donor egg cryobank and makes it likely that this approach becomes the future standard of care. Oocyte donation is one of the last resorts in IVF treatment for couples challenged with infertility problems. However, traditional (fresh) egg donation, as it is performed today, is not very efficient, as typically all eggs from one donor are given to only one recipient, it is arduous as it requires an excellent synchronization between the donor and recipient and there are months or years of waiting time. Because of the development of an efficient oocyte cryopreservation technique, it is now possible to cryo-store donor (as well as non-donor) eggs, maintaining their viability and allowing their use whenever there is demand. Therefore, creating a donor oocyte cryobank would carry many advantages

    The results of seven cocrystallization experiments of the antithyroid drug 6-methyl-2-thiouracil (MTU), C(5)H(6)N(2)OS, with 2,4-diaminopyrimidine, 2,4,6-triaminopyrimidine and 6-amino-3H-isocytosine (viz. 2,6-diamino-3H-pyrimidin-4-one) are reported. MTU features an ADA (A = acceptor and D = donor) hydrogen-bonding site, while the three coformers show complementary DAD hydrogen-bonding sites and therefore should be capable of forming an ADA/DAD N-H...O/N-H...N/N-H...S synthon with MTU. The experiments yielded one cocrystal and six cocrystal solvates, namely 6-methyl-2-thiouracil-2,4-diaminopyrimidine-1-methylpyrrolidin-2-one (1/1/2), C(5)H(6)N(2)OS·C(4)H(6)N(4)·2C(5)H(9)NO, (I), 6-methyl-2-thiouracil-2,4-diaminopyrimidine (1/1), C(5)H(6)N(2)OS·C(4)H(6)N(4), (II), 6-methyl-2-thiouracil-2,4-diaminopyrimidine-N,N-dimethylacetamide (2/1/2), 2C(5)H(6)N(2)OS·C(4)H(6)N(4)·2C(4)H(9)NO, (III), 6-methyl-2-thiouracil-2,4-diaminopyrimidine-N,N-dimethylformamide (2/1/2), C(5)H(6)N(2)OS·0.5C(4)H(6)N(4)·C(3)H(7)NO, (IV), 2,4,6-triaminopyrimidinium 6-methyl-2-thiouracilate-6-methyl-2-thiouracil-N,N-dimethylformamide (1/1/2), C(4)H(8)N(5)(+)·C(5)H(5)N(2)OS(-)·C(5)H(6)N(2)OS·2C(3)H(7)NO, (V), 6-methyl-2-thiouracil-6-amino-3H-isocytosine-N,N-dimethylformamide (1/1/1), C(5)H(6)N(2)OS·C(4)H(6)N(4)O·C(3)H(7)NO, (VI), and 6-methyl-2-thiouracil-6-amino-3H-isocytosine-dimethyl sulfoxide (1/1/1), C(5)H(6)N(2)OS·C(4)H(6)N(4)O·C(2)H(6)OS, (VII). Whereas in cocrystal (I) an R(2)(2)(8) interaction similar to the Watson-Crick adenine/uracil base pair is formed and a two-dimensional hydrogen-bonding network is observed, the cocrystals (II)-(VII) contain the triply hydrogen-bonded ADA/DAD N-H...O/N-H...N/N-H...S synthon and show a one-dimensional hydrogen-bonding network. Although 2,4-diaminopyrimidine possesses only one DAD hydrogen-bonding site, it is, due to orientational disorder, triply connected to two MTU molecules in (III) and (IV).

  13. Development of organ-specific donor risk indices.

    Because of the shortage of deceased donor organs, transplant centers accept organs from marginal deceased donors, including older donors. Organ-specific donor risk indices have been developed to predict graft survival with various combinations of donor and recipient characteristics. Here we review the kidney donor risk index (KDRI) and the liver donor risk index (LDRI) and compare and contrast their strengths, limitations, and potential uses. The KDRI has a potential role in developing new kidney allocation algorithms. The LDRI allows a greater appreciation of the importance of donor factors, particularly for hepatitis C virus-positive recipients; as the donor risk index increases, the rates of allograft and patient survival among these recipients decrease disproportionately. The use of livers with high donor risk indices is associated with increased hospital costs that are independent of recipient risk factors, and the transplantation of livers with high donor risk indices into patients with Model for End-Stage Liver Disease scores indices for liver transplantation, including donor-recipient matching and the retransplant donor risk index. Although substantial progress has been made in developing donor risk indices to objectively assess donor variables that affect transplant outcomes, continued efforts are warranted to improve these indices to enhance organ allocation policies and optimize allograft survival.

    To describe the characteristics of donation behavior and identify reasons, beliefs and feelings relative to this practice, based on the reports of donor women. Personal and social-environmental aspects, which seem to affect donation behavior in donors and former donors, were also investigated. An exploratory, descriptive and cross-sectional study was carried out with women donors at two breast-milk banks within the public health system of the Brazilian Federal District. Data was collected from July to September 2005. The participants were 36 women, aged 14 to 33 years (average=24.78; SD=5.22), with different levels of schooling, 58.3% of which were first-time mothers. Data gathering was based on interviews carried out during home visits. In addition to descriptive statistical analyses of quantitative data, a qualitative data categorical analysis was also performed. The most frequently reported reasons for donating breast milk were altruism and excess milk production. The most frequent time interval for donation was 13 days after delivery. Contact by phone with the milk bank was the most common means of communication used by the majority of participants (n=22) to obtain information that enabled the donating process. Psychosocial aspects identified and the experience of donors can contribute to the empowerment of the formal and informal social donation-support network, in addition to serving as a driver for the implementation of technical and policy strategies in promoting future donation practices.

  15. Donor insemination: eugenic and feminist implications.

    One concern regarding developments in genetics is that, when techniques such as genetic engineering become safe and affordable, people will use them for positive eugenics: to "improve" their offspring by enpowering them with exceptional qualities. Another is whether new reproductive technologies are being used to improve the condition of women or as the tools of a patriarchal system that appropriates female functions to itself and exploits women to further its own ends. Donor insemination is relevant to both of these issues. The degree to which people have used donor insemination in the past for positive eugenic purposes may give some insight into the likelihood of developing technologies being so used in the future. Donor insemination provides women with the opportunity to reproduce with only the most remote involvement of a man. To what degree do women take advantage of this to liberate themselves from male dominance? Through questionnaires and interviews, women who have used donor insemination disclosed their criteria for selecting sperm donors. The results are analyzed for the prevalence of positive eugenic criteria in the selection process and women's attitudes toward minimizing the male role in reproduction.

    Literature is controversial whether organs from living donors have a better graft function than brain dead (BD) and non-heart-beating donor organs. Success of transplantation has been correlated with high-energy phosphate (HEP) contents of the graft. HEP contents in heart, liver, kidney, and pancreas from living, BD, and donation after cardiac death in a pig model (n=6 per donor type) were evaluated systematically. BD was induced under general anesthesia by inflating a balloon in the epidural space. Ten hours after confirmation, organs were retrieved. Cardiac arrest was induced by 9V direct current. After 10min of ventricular fibrillation without cardiac output, mechanical and medical reanimation was performed for 30min before organ retrieval. In living donors, organs were explanted immediately. Freeze-clamped biopsies were taken before perfusion with Celsior solution (heart) or University of Wisconsin solution (abdominal organs) in BD and living donors or with Histidine-Tryptophan-Ketoglutaric solution (all organs) in non-heart-beating donors, after perfusion, and after cold ischemia (4h for heart, 6h for liver and pancreas, and 12h for kidney). HEPs (adenosine triphosphate, adenosine diphosphate, adenosine monophosphate, and phosphocreatine), xanthine, and hypoxanthine were measured by high-performance liquid chromatography. Energy charge and adenosine triphosphate-to-adenosine diphosphate ratio were calculated. After ischemia, organs from different donor types showed no difference in energy status. In all organs, a decrease of HEP and an increase in hypoxanthine contents were observed during perfusion and ischemia, irrespective of the donor type. Organs from BD or non-heart-beating donors do not differ from living donor organs in their energy status after average tolerable ischemia. Copyright © 2013 Elsevier Inc. All rights reserved.

    Some blood donation-related adverse events (AEs) can negatively impact the blood donor return rate (BDRR) and decrease donor retention. One-thousand randomly selected whole-blood donors were interviewed 3 weeks after a 525-mL index whole-blood donation for seven AEs. The number of return visits and duration of follow-up were recorded for each of the 1000 donors. A negative binomial regression analysis was used to determine the contribution of the four most common AEs to the BDRR, and interactions between these AEs were also evaluated. The four most common AEs were bruise alone (15.1%), sore arm "alone" (7.0%), fatigue "alone" (5.1%), and donor reaction "alone" (4.2%), where "alone" is defined to also include donors who had a bruise but no other AE. The estimated BDRR for donations without AEs was 1.32 visits per year. The estimated BDRRs for the four most common AEs were: bruise alone, 1.32 visits per year; sore arm alone, 1.30 visits per year (2% reduction in BDRR); fatigue alone, 1.06 visits per year (20% reduction in BDRR); and donor reaction alone, 0.87 visits per year (34% reduction in BDRR). The BDRR for donor reaction, fatigue, and sore arm together was 0.20 visits per year (85% reduction in BDRR). Donor reaction had the most negative impact on the BDRR. There appears to be a synergistic effect between donor reaction, fatigue, and sore arm. Theoretically, amelioration of some AEs has the potential to improve BDRRs.

    Solid organ transplantation as a treatment for end stage organ failure has been an accepted treatment option for decades. Despite advances in medicine and technology, and increased awareness of organ donation and transplantation, the gap between supply and demand continues to widen. Living donation has been an option that has increased the number of transplants despite the continued shortage of deceased organs. In the early 2000s live donor transplantation reached an all-time high in the United States. As a result, a consensus meeting was convened in 2000 to increase the oversight of living donor transplantation. Both the Centers for Medicare and Medicaid Services and the United Network for Organ Sharing developed regulations that transplant programs performing live donor transplantation. These regulations and guidelines involve the education, evaluation, informed consent process and living donor follow-up care. Two areas in which had significant changes included the psychosocial and the independent living donor advocate (ILDA) evaluation. The purpose of this paper was to outline the current regulations and guidelines associated with the psychosocial and ILDA evaluation as well as provide further recommendations for the administration of a high quality evaluation of living donors. The goals and timing of the evaluation and education of donors; qualifications of the health care providers performing the evaluation; components of the evaluation; education provided to donors; documentation of the evaluation; participation in the selection committee meeting; post-decline and post-donation care of donors is described. Caveats including the paired donor exchange programs and non-directed and directed donation are also considered.

    Full Text Available BACKGROUND Breast Cancer is the most common female cancer worldwide and carries significant psychosocial morbidity. The diagnosis of the disease and the treatment modalities like surgery and chemotherapy contribute to the morbidity. The recognition of the psychosocial morbidity associated with mastectomy can help us formulate effective counselling strategies. The objectives of this study were- to assess the psychosocial morbidity in patients undergoing mastectomy for carcinoma breast, to identify the preoperative variables that predict the morbidity and to find out the correlation between degree of neuroticism of the individual and morbidity. MATERIALS AND METHODS 35 female patients who had mastectomy for breast cancer were evaluated at three time-points, preoperatively, immediately after surgery and 2 months after surgery. Anxiety and depression was assessed using Hospital Anxiety and Depression Scale (HADS, psychological distress was measured using General Health Questionnaire (GHQ-12 and neuroticism was assessed by Eysenck Personality Inventory Neuroticism subscale (EPI-N. RESULTS There was a high level of anxiety, depression and GHQ scores preoperatively with a further worsening of these over the three interviews. Age, marital status and menopausal status were factors which had an influence on psychosocial morbidity. Preoperative EPI-N scores positively correlated with psychosocial morbidity. CONCLUSION There is a high level of psychosocial morbidity in patients undergoing mastectomy for breast cancer and mastectomy seems to worsen it in the first two months after surgery. Our study shows that psychosocial morbidity is affected by age, marital status, menopausal status and level of neuroticism.

    Eye banks use sterile procedures to manipulate the eye, antiseptic measures for ocular surface decontamination, and rigorous criteria for donor selection to minimize the possibility of disease transmission due to corneal grafting. Donor selection focuses on analysis of medical records and specific post-mortem serological tests. To guide and standardize procedures, eye bank associations and government agencies provide lists of absolute and relative contraindications for use of the tissue based on donor health history. These lists are guardians of the Hippocratic principle "primum non nocere." However, each transplantation carries risk of transmission of potentially harmful agents to the recipient. The aim of the procedures is not to eliminate risk, but limit it to a reasonable level. The balance between safety and corneal availability needs to be maintained by exercising prudence without disproportionate rigor.

    In 518 sera from blood donors below 30 years of age neopterin was determined by radioimmunoassay. 21 of these patients (4.05%) showed elevated serum levels for neopterin. By clinical investigation of these cases viral infections of the upper airways were found. Furthermore after elimination of elevated values significant differences in normal neopterin serum levels could be demonstrated for female and male blood donors (p < 0.01). Because elevated neopterin serum levels indicate immune responses to several antigens, determination of neopterin from serum may be useful for detection of infectious blood samples. (author)

    There may be concerns about purely laparoscopic donor right hepatectomy (PLDRH) compared with open donor right hepatectomy, especially when performed by surgeons accustomed to open surgery. This study aimed to describe technical tips and pitfalls in PLDRH. Data from donors who underwent PLDRH at Seoul National University Hospital between December 2015 and July 2017 were analysed retrospectively. Endpoints analysed included intraoperative events and postoperative complications. All operations were performed by a single surgeon with considerable experience in open living donor hepatectomy. A total of 26 donors underwent purely laparoscopic right hepatectomy in the study interval. No donor required transfusion during surgery, whereas two underwent reoperation. In two donors, the dissection plane at the right upper deep portion of the midplane was not correct. One donor experienced portal vein injury during caudate lobe transection, and one developed remnant left hepatic duct stenosis. One donor experienced remnant portal vein angulation owing to a different approach angle, and one experienced arterial damage associated with the use of a laparoscopic energy device. One donor had postoperative bleeding due to masking of potential bleeding foci owing to intra-abdominal pressure during laparoscopy. Two donors experienced right liver surface damage caused by a xiphoid trocar. Purely laparoscopic donor hepatectomy differs from open donor hepatectomy in terms of angle and caudal view. Therefore, surgeons experienced in open donor hepatectomy must gain adequate experience in laparoscopic liver surgery and make adjustments when performing PLDRH. © 2018 BJS Society Ltd Published by John Wiley & Sons Ltd.

    Full Text Available Obesity is currently one of the major public health problems, in both developed and developing countries. Obesity is a risk factor for metabolic syndrome. Increasing rates of childhood obesity and more sedentary lifestyles has led to an age shift in metabolic syndrome which now occurs at an earlier age. Thus, the present study was conducted to get an idea about the occurrence of obesity among adolescent school children, risk factors associated with the condition and the related morbidity among them. MATERIALS AND METHODS: A cross-sectional descriptive study carried out in two higher secondary government girl schools with the help of a pre- designed and pre-tested questionnaire. RESULTS: Out of 245 students 16.73% were overweight and 6.54% were obese. Among overweight students, 59.65% exercised less than 4 hours a week, 61.4% watched TV ≥ 4 hours per week, 87.72% consumed junk food ≥ 4 days per week and 45.61% skipped meals. Puberty related menstrual irregularities, hypothyroidism, acne and stria were more commonly found in overweight students CONCLUSION: The rapidly increasing prevalence of obesity accompanied by unhealthy lifestyle habits among adolescents is one of the most challenging dilemmas of public health importance.

Specifically, the concentration of H atoms and O vacancies (V{sub O}), carrier concentration, and conductivity are investigated by hard X-ray photoelectron spectroscopy, secondary ion mass spectroscopy, thermal desorption spectroscopy, and Hall effect measurements. The results of these experiments suggest that the origin of major donor states is H occupancy of V{sub O} sites. Furthermore, we use first-principles calculations to investigate the influence of the coexistence of V{sub O} and H in crystalline InGaO{sub 3}(ZnO){sub m} (m = 1). The results indicate that when H is trapped in V{sub O}, a stable complex is created that serves as a shallow-level donor.

    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.

    Morbid obesity (body mass index (BMI) > or =40 kg/m2) is associated with substantially increased morbidity and mortality from chronic health conditions and with poorer health-related quality of life; however, less is known about the impact of morbid obesity on healthcare expenditures. To examine the impact of morbid obesity on healthcare expenditures using a nationally representative sample of US adults. We performed a cross-sectional analysis of 16 262 adults from the 2000 Medical Expenditure Panel Survey, a nationally representative survey of the noninstitutionalized civilian population of the United States. Per capita healthcare expenditures were calculated for National Institutes of Health BMI categories, based on self-reported height and weight, using a two-part, multivariable model adjusted for age, gender, race, income, education level, type of health insurance, marital status, and smoking status. Odds of incurring any healthcare expenditure and per capita healthcare expenditures associated with morbid obesity in 2000. When compared with normal-weight adults, the odds of incurring any healthcare expenditure in 2000 were two-fold greater among adults with morbid obesity. Per capita healthcare expenditures for morbidly obese adults were 81% (95% confidence interval (CI): 48-121%) greater than normal-weight adults, 65% (95% CI: 37-110%) greater than overweight adults, and 47% (95% CI: 11-96%) greater than adults with class I obesity. Excess costs among morbidly obese adults resulted from greater expenditures for office-based visits, outpatient hospital care, in-patient care, and prescription drugs. Aggregate US healthcare expenditures associated with excess body weight among morbidly obese US adults exceeded $11 billion in 2000. The economic burden of morbid obesity among US adults is substantial. Further research is needed to identify interventions to reduce the incidence and prevalence of morbid obesity and improve the health and economic outcomes of morbidly

    Adverse donor reactions can result in injury and decrease the likelihood of donor return. Reaction reports captured in the blood center's database provide an incomplete picture of reaction rates and risk factors. We performed an anonymous survey, mailed to 40,000 donors in 2008, including questions about symptoms, height, weight, sex, and donation status. Reaction rates were compared to those recorded in our database. Possible risk factors were assessed for various reactions. The response rate was 45.5%. A total of 32% of first-time and 14% of repeat donors reported having any adverse symptom, most frequently bruising (84.9 per 1000 donors) or feeling faint or weak (66.2 per 1000). Faint reactions were two to eight times higher than reported in our database, although direct comparison was difficult. Younger age, female sex, and first-time donation status were risk factors for systemic and arm symptoms. In females, low estimated blood volume (EBV) was a risk factor for systemic symptoms. Only 51% of donors who consulted an outside physician also called Canadian Blood Services. A total of 10% of first-time donors with reactions found adverse effects information inadequate. This study allowed us to collect more information about adverse reactions, including minor symptoms and delayed reactions. Based on our findings of the risk factors and frequency of adverse reactions, we are implementing more stringent EBV criteria for younger donors and providing more detailed information to donors about possible adverse effects and their management. © 2012 American Association of Blood Banks.

    Remuneration for blood donors, in the way as presently handled by governmental and communal blood transfusion services in Germany, is not generally accepted. It is feared that donors are recruited with increased risk to transmit infectious diseases, especially AIDS. Alternative incentives are discussed. After the so-called AIDS scandal in Germany, a change in the donor motivation was to be expected, associated with an increased willingness to renounce remuneration. Therefore, we performed the present survey, in which we evaluated the donor's willingness to renounce remuneration, possibilities of cashless remuneration and other alternative incentives. During March and April 1994, a total of 1,157 blood donors of the University Blood Bank Marburg were questioned anonymously by a questionnaire in the framework of whole-blood donations. Beside the above-mentioned aspects demoscopic data were included (age, sex, profession, journey). Cutting of remuneration without any other compensation was refused by 86.1% of the donors, 77% would not want to further donate blood in this case. Transfer of money to a bank account instead of cash payment was accepted by 78.6%, the use of non-negotiable cheques by 68.7%. Alternative compensation by tickets for theater, concert, cinema or coupons for restaurants met with the approval of only 27.3%; under these circumstances, 36.9% would be willing to continue blood donation. With increasing age and number of donations, but largely independent of social status, donors attached greater importance to retention of remuneration. Cutting of remuneration would result in a considerable reduction of the willingness to donate blood within the population of donors of the governmental and communal blood transfusion services. However, an increase of virus safety of the blood products would not be reached in this way, since especially the long-term donors would be driven away. Considerable bottlenecks, particularly in the specific blood supply of

    Deterministic control over the location and number of donors is crucial to donor spin quantum bits (qubits) in semiconductor based quantum computing. In this work, a focused ion beam is used to implant antimony donors in 100 nm × 150 nm windows straddling quantum dots. Ion detectors are integrated next to the quantum dots to sense the implants. The numbers of donors implanted can be counted to a precision of a single ion. In low-temperature transport measurements, regular Coulomb blockade is observed from the quantum dots. Charge offsets indicative of donor ionization are also observed in devices with counted donor implants.

    Unrelated Bone marrow transplant was initiated thirty years ago. Though there are over millions of donors registered with the bone marrow registries worldwide, Asian patients rarely find a match with all these donors. Tzu Chi Marrow Donor Registry was established to meet this need. It has become the largest Asian marrow donor registry in the world. With the introduction of high technology to test the HLA of the donors and recipients, the success rate of bone marrow transplant is greatly improved among Asian countries. 50% of blood disease Asian patients who cannot find a bone marrow matched donor will be complemented by the establishment of cord blood banks in Taiwan.

    To evaluate the association between newborn gender and the risk for later pediatric respiratory morbidity. A population based cohort analysis was performed by comparing the risk of long-term respiratory morbidity (until 18 years of age) according to gender. Respiratory morbidity included hospitalizations involving pneumonia, asthma, bronchitis, bronchiolitis, upper respiratory tract infection (URTI), influenza, and bronchiectasis. Deliveries occurred between the years 1991 and 2014 in a tertiary medical center. Kaplan-Meier survival curves were constructed to compare cumulative respiratory morbidity. A Cox proportional hazards model controlled for confounders. During the study period 240 953 newborns met the inclusion criteria. Among them, 118 113 were females (49.0%) and 122 840 were males (51.0%). During the 18 years of follow-up, 13 719 (5.7%) different newborns were hospitalized with respiratory related morbidity.

    IVF using donated oocytes offers benefits to many infertile patients, yet the technique also raises a number of ethical concerns, including worries about potential physical and psychological risks to oocyte donors. In the USA, oversight of oocyte donation consists of a combination of federal and state regulations and self-regulatory guidelines promulgated by the American Society for Reproductive Medicine. This study assesses compliance with one of these self-regulatory guidelines - specifically, ASRM's preferred minimum age for donors of 21. To assess compliance, 539 oocyte donor recruitment advertisements from two recruitment channels (Craigslist and college newspapers) were collected and evaluated. Of these, 61% in the Craigslist dataset and 43% in the college newspaper dataset listed minimum ages between 18 and 20, which is inconsistent with ASRM's preferred minimum age recommendation of 21. Advertisements placed by oocyte donor recruitment agencies were more likely than advertisements placed by clinics to specify minimum ages between 18 and 20. These results indicate that ASRM should evaluate and consider revising its donor age guidelines. IVF using donated human eggs can help many patients who have difficulty having children. However, the technique also raises ethical concerns, including concerns about potential physical and psychological harms to egg donors. In the USA, oversight of egg donation relies on a combination of federal and state regulation and professional self-regulation. Governmental regulations address only limited aspects of egg donation, such as the potential spread of infectious diseases and the reporting of success rates, leaving voluntary guidelines developed by an association of medical professionals to address most issues, including ethical concerns raised by the practice. One of these voluntary guidelines recommends that egg donors should be at least 21 years of age. In this article, we analysed 539 egg donor recruitment advertisements

  17. Criteria for selecting organ donors and recipients.

    1990-11-01

    As there is a world-wide shortage of organs for transplantation, the selection of the patients is more defined by the availability of transplantable organs than by the medical condition of the potential recipient. This shortage of cadaveric organs is mainly responsible for the use of living donors. With HLA identical sibling donors the results are better than with cadaveric organs, but the ethical problems are usually underestimated. For the parent-to-child donation, the HLA compatibility is less than what could be achieved with well-matched cadaveric donors. The use of genetically unrelated donors is unacceptable from the ethical as well as from the medical point of view. The short- and long-term risk of donation has been insufficiently documented. The experience with the introduction of an opting-out legislation in Belgium in 1987 demonstrates that the shortage of cadaveric organs can be overcome. Harmonization of the legislation is, however, necessary so as to achieve comparable organ retrieval rates between countries participating in organ-exchange organisations.

    Malaysians indicating that they did not intend to become organ donors upon their death were surveyed regarding interest in non-fungible financial incentives to be granted to surviving family members. Among the 730 (56% of the total sample of 1311) indicating unwillingness to be donors, 29.6% (216/730) subsequently indicated that they would be willing donors if the government introduced policies that, upon their death, "rewarded your (their) family with incentives for your (their) deeds." Among the 69% (504/730) who insisted that they would not become organ donor even with incentive, nearly 80% (404/501) of them were able to identify relevant incentives they thought should be provided by the state to those who make organ donations upon death. The majority of both groups preferred the state provide medical benefits to a surviving family member, suggesting this may be an attractive policy option for the state to raise the deceased organ donation pool. © 2013 John Wiley & Sons A/S.

    Nowadays, several treatments exist to treat terminal chronic renal failure. Best results for the recipients are obtained with kidney transplantation concerning mortality and quality of life. Transplantation is also the cheaper option for society. Living kidney donation raises the issue of the becoming of the donor, an absolutely healthy subject who gets to a surgical procedure. The becoming of living kidney donors has been compared with the one of controls subjects in several studies. The evaluations focused on the complications of nephrectomy in the short and long-term: kidney failure, hypertension, proteinuria, possibility of pregnancy, quality of life, and mortality. The first results did not show any risk linked to kidney donation, compared to general population. However, since 2013, kidney donors were found at higher risk for kidney failure and even for mortality, compared with controls selected like donor candidates. The risk of kidney donation is nevertheless acceptable and minimal, on the condition of rigorous selection of candidates and regular follow-up.

    Intestinal volvulus (IV) can occur at various sites of the gastrointestinal tract. In Europe, IV in children is most frequently due to malrotation but in Asia Ascaris infestation is a common cause. This report reviews the experience with IV in children in Tunisia; analyzes the aetiologies as well as the clinical presentations and the benefits of the Ladd's procedure in the treatment of the IV. The authors retrospectively reviewed the case records of all children with IV from January 2000 to December 2009 at the Tunis Children's Hospital. There were 22 boys and nine girls with an age range of one day to four years. Twenty-five (80%) patients presented during the neonatal period. The most common presentation was bilious vomiting and dehydration. The aetiology was identified in all patients: Anomalies in rotation (n=22), omphalo-mesenteric duct (n=3), internal hernia (n=3), cystic lymphangioma (n=2), caocal volvulus (n=1). The bowel resection rate for gangrene was 16%. All patients with malrotation had Ladd's procedure performed. Five patients (19%) developed wound infections. One patient presented with adhesive small bowel obstruction. There were no recurrences following Ladd's procedure for malrotation. Two neonates (6%) died from overwhelming infections. Intestinal volvulus in our environment differs in aetiology from other reports. The resection rates are not similar, however. Early diagnosis reduced the high morbidity and mortality in our study.

    Full Text Available Background - Transplantation of the small intestine is a surgical procedure currently under investigation for its possible application in the treatment of patients with short bowel syndrome, aiming at the reintroduction of an oral diet. Aim - To define the morbidity and mortality of intestinal transplantation in small animals using microsurgery. Intra and postoperative morbidity and mortality were studied in Wistar rats submitted to orthotopic intestinal allotransplantation. Material and Method - The animals were divided into three groups: group A (37 donor animals, group B (37 recipient animals, and group C (10 control animals. Group B was divided into three subgroups according to survival time. Subgroup TI consisted of animals that died during surgery or due to causes directly related to surgical intervention, subgroup T2 consisted of animals that died between the 4th and 29th postoperative day, and subgroup T3 consisted of animals that survived after 30 days. Transplanted animals were evaluated in terms of surgical technique used (vascular and intestinal anastomosis, graft quality, surgical time, and clinical parameters. The animals that died by the 29th postoperative day were submitted to autopsy and the remaining ones were sacrificed after 30 days. Result - There was a high rate of complication of a surgical nature. Early mortality rate, i.e., mortality up to the third postoperative day, was 54% with vascular anastomosis being the major cause of death. Surgical time was evaluated in a restricted and homogeneous group and showed a strong prognostic value in terms of successful transplantation. Clinical parameters such as weight loss, reduction of ingestion, reduction of motor activity and diarrhea were directly correlated with acute rejection. Conclusion - The experimented intestinal transplant is a procedure companied by considerable morbidity and mortality due to surgical complications in postoperative period, vascular anastomosis and

    Optimum use of donor organs can increase the reach of the transplantation therapy to more patients on waiting list. The heart transplantation (HTx) has remained stagnant in United States over the past decade at approximately 2,500 HTx annually. With the use of the United Network of Organ Sharing (UNOS) deceased donor database (DCD) we aimed to evaluate donor factors predicting donor heart utilization. UNOS DCD was queried from 2005 to 2014 to identify total number of donors who had at least one of their organs donated. We then generated a multivariate logistic regression model using various demographic and clinical donor factors to predict donor heart use for HTx. Donor hearts not recovered due to consent or family issues or recovered for nontransplantation reasons were excluded from the analysis. During the study period there were 80,782 donors of which 23,606 (29%) were used for HTx, and 38,877 transplants (48%) were not used after obtaining consent because of poor organ function (37%), donor medical history (13%), and organ refused by all programs (5%). Of all, 22,791 donors with complete data were used for logistic regression (13,389 HTx, 9,402 no-HTx) which showed significant predictors of donor heart use for HTx. From this model we assigned probability of donor heart use and identified 3,070 donors with HTx-eligible unused hearts for reasons of poor organ function (28%), organ refused by all programs (15%), and recipient not located (9%). An objective system based on donor factors can predict donor heart use for HTx and may help increase availability of hearts for transplantation from existing donor pool.

    The aim of this study was to describe the epidemiology and utilization of anti-hepatitis B core protein(+) and anti-hepatitis C virus(+) organ donor referrals in a large organ procurement organization. Between 1995 and 2006, 3,134 deceased organ donor referrals were tested for anti-HBc and anti-HCV using commercial assays. The prevalence of anti-HCV(+) organ donor referrals significantly increased from 3.4% in 1994-1996 to 8.1% in 2003-2005 (P organ donor referrals remained unchanged at 3%-4% (P = .20). The 112 anti-HBc(+) (3.5%) and 173 anti-HCV(+) (5.5%) organ donor referrals were significantly older and more likely to be noncaucasian than seronegative organ donor referrals (P donor organs were significantly lower compared with seronegative organ donors (P donors over time (21% vs 46%; P = .026), whereas utilization of anti-HCV(+) liver donors remained unchanged over time (5% vs 18%; P = .303). In summary, the proportion of anti-HCV(+) organ donor referrals has significantly increased and the proportion of anti-HBc(+) organ donor referrals has remained stable.

    DIDS is a unique form of combined immune deficiency characterized by an unusual susceptibility to cutaneous viral infections, severe allergies with eosinophilia and elevated immunoglobulin E titers, autoimmunity, and cancer. HSCT is considered the standard of care for this deadly disease. We have retrospectively analyzed the outcome of allogeneic HSCT from unrelated donors in patients with DIDS. Data from four patients, with five transplants, are presented. All patients received transplants from unrelated donors' BM, except for one patient who received a cord blood transplant. The conditioning regimens were based on myeloablative protocols for BM derived transplants; a NM regimen was pursued for the patient who received a cord blood transplant, which resulted in graft rejection. Although recurrent pneumonia and skin infections resolved immediately after transplantation, all patients subsequently developed human herpesvirus infection, including cutaneous herpetic lesions, cytomegalovirus reactivation, and zona zoster, which could be attributed to the use of ATG. Despite the presence of serious morbidities prior to transplantation, all patients recovered successfully. DIDS can be successfully treated with allogeneic HSCT from unrelated donors following a myeloablative conditioning regimen, with a reasonable safety profile. © 2017 John Wiley & Sons A/S.

    Deceased donor liver transplant (DDLT) is an uncommon procedure in India. We present our experience of DDLT from a public sector teaching hospital. A retrospective analysis of all DDLT was performed from April 2012 till September 2016. Demographics, intraoperative, donor factors, morbidity, and outcome were analyzed. During the study period, 305 liver transplants were performed, of which 36 were DDLT (adult 32, pediatric 4; 35 grafts; 1 split). The median age was 42.5 (1-62) years; 78% were men. The median donor age was 28 (1-77) years; 72.2% were men. About 45% of organs were procured from outside of Delhi and 67% of all grafts used were marginal. Three of 38 liver grafts (7.8%) were rejected due to gross steatosis. Commonest indication was cryptogenic cirrhosis (19.4%). The median model for end-stage liver disease sodium and pediatric end-stage liver disease scores were 23.5 (9-40) and 14.5 (9-22), respectively. Median warm and cold ischemia times were 40 (23-56) and 396 (111-750) min, respectively. Major morbidity of grade III and above occurred in 63.8%. In hospital (90 days), mortality was 16.7% and there were two late deaths because of chronic rejection and biliary sepsis. The overall survival was 77.8% at median follow up of 8.6 (1-54) months. DDLT can be performed with increasing frequency and safety in a public sector hospital. The perioperative and long-term outcomes are acceptable despite the fact that most organs were extended criteria grafts.

    Full Text Available Aim: A prospective study was undertaken to evaluate the use of 2% (w/v alcoholic chlorhexidine gluconate (2% AlcCHG in donor arm preparation, to monitor the contamination rate of blood products after the collection and to find incidence of transfusion associated bacteremia. Settings and Design: Optimal skin antisepsis of the phlebotomy site is essential to minimize the risk of contamination. Food and Drug Administration (FDA in India has recommended antisepsis with three-step regimen of spirit-10% povidone iodine-spirit for donor arm antisepsis, but not with chlorhexidine, which is recommended by many other authors. Material and Methods: A total of 795 donors were studied from July 2011 to January 2012. Spirit-10% povidone iodine-spirit was used for 398 donors and 2% AlcCHG was used for 397 donors with the two-step method for arm antisepsis. Swabs were collected before and after use of antiseptic agents for all the donors. All the blood products collected from donors with growth in post-antisepsis swabs were cultured. A total of 123 various blood products were cultured irrespective of the method and result of antisepsis was observed. A total of seven patients had mild transfusion reaction. The transfused blood products, blood and urine specimen of the patients who had transfusion reaction were also cultured. Results: Seven donors out of 398 donors had growth in post-antisepsis swab with spirit-10% povidone iodine-spirit protocol and three donors out of 397 donors had growth in post-antisepsis swab with 2% AlcCHG protocol. All blood products collected from donors who had growth in post-antisepsis swabs when cultured had no growth. There was no contamination of blood products. Conclusions: Two percent (w/v alcoholic chlorhexidine gluconate with two-step protocol can be used as an antiseptic agent for donor arm preparation without considerable cost difference. It is at par with spirit 10% povidone iodine spirit protocol as suggested by FDA in India

    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.

    Previous studies have demonstrated that obese patients (BMI >30) undergoing laparoscopic colectomy have longer operative times and increased complications when compared to non-obese cohorts. However, there is little data that specifically evaluates the outcomes of obese patients based on the degree of their obesity. The aim of this study was to evaluate the impact of increasing severity of obesity on patients undergoing laparoscopic colectomy. A retrospective review was performed of all patients undergoing laparoscopic colectomy between 1996 and 2013. Patients were classified according to their BMI as obese (BMI 30.0-39.9), morbidly obese (BMI 40.0-49.9), and super obese (BMI >50). Main outcome measures included conversion rate, operative time, estimated blood loss, post-operative complications, and length of stay. There were 923 patients who met inclusion criteria. Overall, 604 (65.4%), 257 (27.9%), and 62 (6.7%) were classified as obese (O), morbidly obese (MO), and super obese (SO), respectively. Clinicopathologic characteristics were similar among the three groups. The SO group had significantly higher conversion rates (17.7 vs. 7 vs. 4.8%; P = 0.031), longer average hospital stays (7.1 days vs. 4.9 vs. 3.4; P = 0.001), higher morbidity (40.3 vs. 16.3 vs. 12.4%; P = 0.001), and longer operative times (206 min vs. 184 vs. 163; P = 0.04) compared to the MO and O groups, respectively. The anastomotic leak rate in the SO (4.8%; P = 0.027) and MO males (4.1%; P = 0.033) was significantly higher than MO females (2.2%) and all obese patients (1.8%). Increasing severity of obesity is associated with worse perioperative outcomes following laparoscopic colectomy.

    2013-04-01

    In the 2009 reform of the German collective remuneration system for outpatient medical care, on the level of overall remuneration, the morbidity risk was transferred to the health funds fulfilling a long-term demand of physicians. Nevertheless not transferring morbidity adjustment to the levels of physician groups and singular practices can lead to budgets not related to patient needs and to incentives for risk selection for individual doctors. The systematics of the distribution of overall remuneration in the German remuneration system for outpatient care are analysed focusing on the aspect of morbidity adjustment. Using diagnostic and pharmaceutical information of about half a million insured subjects, a risk adjustment model able to predict individual expenditures for outpatient care for different provider groups is presented. This model enables to additively split the individual care burden into several parts attributed to different physician groups. Conditions for the use of the model in the distribution of overall remuneration between physician groups are developed. A simulation of the use of diagnoses-based risk adjustment in standard service volumes then highlights the conditions for a successfull installation of standard service volumes representing a higher degree of risk adjustment. The presented estimation model is generally applicable for the distribution of overall remuneration to different physician groups. The simulation of standard service volumes using diagnosis-based risk adjustment does not provide a more accurate prediction of the expenditures on the level of physician practices than the age-related calculation currently used in the German remuneration system for outpatient medical care. Using elements of morbidity-based risk adjustment the current German collective system for outpatient medical care could be transformed towards a higher degree of distributional justice concerning medical care for patients and more appropriate incentives

    Full Text Available Objectives: The introduction of the living donor liver transplantation (LDLT in Egypt as in elsewhere, has raised important psychological conflicts and ethical questions. The objective of this study was to get better understanding of the potential donors’ motives towards LDLT.Methods:This study was conducted on consecutive 193 living –liver donors who underwent partial hepatectomy as donors for LDLT during the period between April 2003 and January 2013, at the National Liver Institute Menoufeyia University, Egypt. Potential donors were thoroughly evaluated preoperatively through a screening questionnaire and interviews as regard their demographic data, relationship to the potential recipient and motives towards proceeding to surgery. They were assured that the information shared between them and the transplant centre is confidential. Results.The donors’ mean age was 25.53± 6.39 years with a range of 18-45 years. Males represented 64.7 % and females were 35.3%. The most common donors (32.1%, n_62, were sons and daughters to their parents (sons: n_43, daughters: n_19 while parents to their offsprings represent 15% (mothers: n_21, fathers: n_8. Brothers and sisters represent 16.5 % (brothers: n_22, sisters: n_10. Nephews & nieces giving their uncles or aunts were 14%. The number of wives donating to their husbands was 11 (5.7%. Interestingly, there was no single husband who donated his wife. Among the remaining donors, there were 11 cousins & one uncle. Unrelated donors were 20 (10.4%. Several factors seemed to contribute to motivation for donation: the seriousness of the potential recipient condition, the relationship and personal history of the donor to the potential recipient, the religious beliefs, the trust in the health care system, and family dynamics and obligations.Conclusions. Absolute absence of coercion on the living-liver donor’s motives may not be realistic because of the serious condition of the potential recipient. It is

    Full Text Available Hematopoietic stem cell transplantation (HSCT is a medical procedure in the field of hematology and oncology, most often performed for patients with certain cancers of the blood or bone marrow. A lot of patients have no suitable HLA-matched donor within their family, so physicians must activate a “donor search process” by interacting with national and international donor registries who will search their databases for adult unrelated donors or cord blood units (CBU. Information and communication technologies play a key role in the donor search process in donor registries both nationally and internationaly. One of the major challenges for donor registry computer systems is the development of a reliable search algorithm. This work discusses the top-down design of such algorithms and current practice. Based on our experience with systems used by several stem cell donor registries, we highlight typical pitfalls in the implementation of an algorithm and underlying data structure.

    Anthropometric data are important indicators of child health. This study sought to determine whether anthropometric data of extreme weight were significant predictors of perioperative morbidity in pediatric surgery. This was a cohort study of children 29 days up to 18 years of age undergoing surgical procedures at participating American College of Surgeons' NSQIP Pediatric hospitals in 2011 and 2012. The primary outcomes were composite morbidity and surgical site infection. The primary predictor of interest was weight percentile, which was divided into the following categories: ≤5(th) percentile, 6(th) to 94(th), or ≥95(th) percentile. A hierarchical multivariate logistic model, adjusting for procedure case mix, demographic, and clinical patient characteristic variables, was used to quantify the relationship between weight percentile category and outcomes. Children in the ≤5th weight percentile had 1.19-fold higher odds of overall postoperative morbidity developing than children in the nonextreme range (95% CI, 1.10-1.30) when controlling for clinical variables. Yet these children did not have higher odds of surgical site infection developing. Children in the ≥95(th) weight percentile did not have a significant increase in overall postoperative morbidity. However, they were at 1.35-fold increased odds of surgical site infection compared with those in the nonextreme range when controlling for clinical variables (95% CI, 1.16-1.57). Both extremely high and extremely low weight percentile scores can be associated with increased postoperative complications after controlling for clinical variables.

    Refinements in donor management have resulted in increased numbers and quality of grafts after neurologic death. We hypothesize that the increased use of hormone replacement therapy (HRT) has been accompanied by improved outcomes over time. Using the Organ Procurement and Transplant Network donor database, all brain-dead donors procured from July 1, 2001 to June 30, 2012 were studied. Hormone replacement therapy was identified by an infusion of thyroid hormone. An expanded criteria donor was defined as age 60 years or older. Incidence of HRT administration and number of donors and organs recovered were calculated. Using the Organ Procurement and Transplant Network thoracic recipient database transplant list, wait times were examined. There were 74,180 brain-dead donors studied. Hormone replacement therapy use increased substantially from 25.6% to 72.3% of donors. However, mean number of organs procured per donor remained static (3.51 to 3.50; p = 0.083), and the rate of high-yield donors decreased (46.4% to 43.1%; p donors decreased (42.1% to 33.9%; p donors (22.1% to 26%). Despite this, there has been an increase in the raw number of donors (20,558 to 24,308; p organs (5,857 to 6,945; p organs per traumatic brain injury donor (4.02 to 4.12; p = 0.002) and a decrease in days on the waiting list (462.2 to 170.4 days; p donors has been accompanied by increased organ availability overall. Potential mechanisms might include successful conversion of previously unacceptable donors and improved recovery in certain subsets of donors. Copyright © 2014 American College of Surgeons.

    Background: Preoperative anemia may affect postoperative mortality and morbidity following elective cranial operations. Methods: The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was used to identify elective cranial neurosurgical cases (2006-2012). Morbidity was defined as wound infection, systemic infection, cardiac, respiratory, renal, neurologic, and thromboembolic events, and unplanned returns to the operating room. For 30-day postoperative mortality and morbidity, adjusted odds ratios (ORs) were estimated with multivariable logistic regression. Results: Of 8015 patients who underwent elective cranial neurosurgery, 1710 patients (21.4%) were anemic. Anemic patients had an increased 30-day mortality of 4.1% versus 1.3% in non-anemic patients (P neurosurgery was independently associated with an increased risk of 30-day postoperative mortality and morbidity when compared to non-anemic patients. A hematocrit level below 33% (Hgb 11 g/dl) was associated with a significant increase in postoperative morbidity. PMID:25422784

    The structural and dynamic properties of a flexible peptidic chain codetermine its biological activity. These properties are imprinted in intrachain site-to-site distances as well as in diffusion coefficients of mutual site-to-site motion. Both distance distribution and diffusion determine the extent of Förster resonance energy transfer (FRET) between two chain sites labeled with a FRET donor and acceptor. Both could be obtained from time-resolved FRET measurements if their individual contributions to the FRET efficiency could be systematically varied. Because the FRET diffusion enhancement (FDE) depends on the donor-fluorescence lifetime, it has been proposed that the FDE can be reduced by shortening the donor lifetime through an external quencher. Benefiting from the high diffusion sensitivity of short-distance FRET, we tested this concept experimentally on a (Gly-Ser)(6) segment labeled with the donor/acceptor pair naphthylalanine/2,3-diazabicyclo[2.2.2]oct-2-ene (NAla/Dbo). Surprisingly, the very effective quencher potassium iodide (KI) had no effect at all on the average donor-acceptor distance, although the donor lifetime was shortened from ca. 36 ns in the absence of KI to ca. 3 ns in the presence of 30 mM KI. We show that the proposed approach had to fail because it is not the experimentally observed but the radiative donor lifetime that controls the FDE. Because of that, any FRET ensemble measurement can easily underestimate diffusion and might be misleading even if it employs the Haas-Steinberg diffusion equation (HSE). An extension of traditional FRET analysis allowed us to evaluate HSE simulations and to corroborate as well as generalize the experimental results. We demonstrate that diffusion-enhanced FRET depends on the radiative donor lifetime as it depends on the diffusion coefficient, a useful symmetry that can directly be applied to distinguish dynamic and structural effects of viscous cosolvents on the polymer chain. We demonstrate that the

    South Korea's official development assistance (ODA) has been increasing rapidly and will continue to do so. Korea is one of the few countries which have successfully transitioned from a recipient to a donor. It became a member of DAC (development assistance committee), OECD in November 2009. Korea......'s ODA policy, along with its growth in quantity, is at a crossroads for the enhancement of its quality. Discussions and debates are going on regarding the reforms in Korea's ODA activities, and this paper examines key issues raised. It first reviews the past and present of Korea's ODA, and identifies...... like the objective of ODA, positioning of Korea's ODA as an emerging donor and the nature of aid to North Korea. We also argue that a shift of ODA policy is required to promote reform, based on a thorough reflection on the role of ODA in the alleviation of poverty and promoting sustainable development...

    SUMMARY Dietary changes may partly explain the high burden of asthma in industrialized nations. Experimental studies have motivated a significant number of observational studies of the relation between vitamins (A, C, D, and E) or nutrients acting as methyl donors (folate, vitamin B12, and choline) and asthma. Because observational studies are susceptible to several sources of bias, well-conducted randomized controlled trials (RCTs) remain the “gold standard” to determine whether a vitamin or nutrient has an effect on asthma. Evidence from observational studies and/or relatively few RCTs most strongly justify ongoing and future RCTs of: 1) vitamin D to prevent or treat asthma, 2) choline supplementation as adjuvant treatment for asthma, and 3) vitamin E to prevent the detrimental effects of air pollution in subjects with asthma. At this time, there is insufficient evidence to recommend supplementation with any vitamin or nutrient acting as a methyl donor to prevent or treat asthma. PMID:24461761

    Deceased donor organ transplantation (DDOT) accounts for DKT) and 19 single (SKT). Fourteen donors had hypertension, a cerebrovascular accident as the cause of death, 9 had both, and 4 had diabetes. Mean donor age was 70.3 +/- 8.9 years. Decisions on the procedure were based upon frozen section biopsy in 13 of 21 donors. Mean DKT donor age was 76 +/- 9.7 years versu 64 +/- 5.7 years of SKT donors. The native kidney diseases were chronic glomerulonephritis (n = 14), diabetic nephropathy (n = 7), tubulointerstitial nephritis (n = 4) and polycystic kidney disease, focal segmental glomerulosclerosis, lupus nephritis and patchy cortical necrosis, (n = 1 each). Mean recipient age of DKT versus SKT was 43.5 versus 42.3 years. All recipients received rabbit anti-thymocyte globulin, followed by steroid, mycophenolate mofetil/calcinueurin inhibitor. Over a mean follow-up of 341 days, the mean serum creatinine (SCr) of 25/29 patients was 1.60 mg/dL (range, 1.0-2.6). The mean SCr of SKT patients was 1.59 +/- 0.63 mg/dL and of DKT, 1.62 +/- 0.48 mg/dL. Ten patients had delayed graft function and 11 had biopsy proven acute tubular necrosis. Seven (24%) patients had rejection (grade 3 Banff update '05, type IA; 4, type 2A); 6 responded to antirejection; 1 graft was lost at 7 months due to chronic rejection. Three (10.3%) patients were lost, 1 each due to AMI, sepsis, and CMV disease. In the circumstances of organ shortage, DDOT with expanded criteria donor is a feasible option.

    Donor availability remains the primary limiting factor for organ transplantation today. The purpose of this study was to examine the causes of procurement failure amongst potential organ donors. After Institutional Review Board approval, all surgical intensive care unit (SICU) patients admitted to the LAC+USC Medical Center from 01/2006 to 12/2008 who became potential organ donors were identified. Demographics, clinical data, and procurement data were abstracted. In non-donors, the causes of procurement failure were documented. During the 3-year study period, a total of 254 patients were evaluated for organ donation. Mean age was 44.8±18.7 years; 191 (75.2%) were male, 136 (53.5%) were Hispanic, and 148 (58.3%) were trauma patients. Of the 254 patients, 116 (45.7%) were not eligible for donation: 34 had multi-system organ failure, 24 did not progress to brain death and had support withdrawn, 18 had uncontrolled sepsis, 15 had malignancy, 6 had human immunodeficiency virus or hepatitis B or C, and 19 patients had other contraindications to organ donation. Of the remaining 138 eligible patients, 83 (60.2%) did not donate: 56 because the family denied consent, 9 by their own choice. In six, next of kin could not be located, five died because of hemodynamic instability before organ procurement was possible, four had organs that could not be placed, and three had their organs declined by the organ procurement organization. The overall consent rate was 57.5% (n=67). From the 55 donors, 255 organs were procured (yield 4.6 organs/donor). Of all patients screened for organ donation, only a fifth actually donated. Denial of consent was the major potentially preventable cause of procurement failure, whereas hemodynamic instability accounted for only a small percentage of donor losses. With such low conversion rates, the preventable causes of procurement failure warrant further study.

    The purpose of World Blood Donor Day (WBDD) is to raise awareness for the importance of blood donation. The aim of this study was to quantify the impact of WBDD on digital information seeking and donor recruitment. Google Trends data were used to quantify seeking behavior on "blood donation" and "blood donor." Differences in relative search volume (RSV) between the 3 weeks surrounding WBDD and the rest of the year were calculated. Second, mean differences in RSV were compared to assess the additional effect of hosting using translated search terms. Third, we compared the period around WBDD with the control period regarding page views of the Sanquin website and Facebook likes and number of newly registered donors in 2016. The mean RSV for "blood donation" in the period of interest was 78.6, compared to 72.1 in the control period (difference, 6.5; 95% confidence interval [95% CI], 1.2-11.8). For "blood donor" this was 78.9 compared to 65.9 (difference, 12.9; 95% CI, 8.1-17.8). We found no additional effect of hosting. In the period of interest, the website of Sanquin was visited 6862 times a day and 4293 times in the control period (difference, 2569; 95% CI, 1687-3451). In June 2016, 54.6% (95% CI, 53.0-56.2) more new donors were registered compared to the control period. An international campaign like WBDD raises the awareness of blood donation and is effective in convincing people to register as blood donors. © 2017 AABB.

    The ethical debate surrounding transplant practices questions our societies. International recommendations set out numerous precautions which must be taken to ensure that donors act with their free will. While in most countries, including France, organ donation is a voluntary and non-commercial act, a black market exists in the world resulting in the trafficking of organs and tragic transplant tourism.

    Full Text Available The present study was designed to investigate hemochromatosis patients' suitability as blood donors as well as their perceptions and experience with the current public donation system. Participants were gathered from a list of current hemochromatosis patients (n=120 and members of the Canadian Hemochromatosis Society (n=1000. Of the 1120 surveys mailed out to these groups, 801 surveys were returned completed. The sample respondents had a mean age of 57.44 years (SD=12.73; range 19 to 87 years, and 57% were men. It was found that 20% (160 of the respondents have donated blood since their diagnosis; however, only 12% of the respondents indicated that they use voluntary blood donation as a means of maintaining their iron levels. Forty per cent of the respondents indicated that they had been refused from voluntary donation. Despite the fact that in May 2001 the Canadian Blood Services, in collaboration with the Canadian Hemochromatosis Society, began a promotion campaign to encourage hemochromatosis patients to become voluntary blood donors, the present study found that 15% of the respondents reported having been refused from the voluntary blood donation service due to the diagnosis of hemochromatosis. With respect to quality of life, it was found that individuals who donate blood were generally healthier with respect to physical functioning and bodily pain, however, these findings may indicate that hemochromatosis patients who are healthier are better able to donate at public blood banks, rather than that voluntary blood donation has an effect on the donors' physical functioning over phlebotomy clinic users. These study findings suggest that although there may be other medical factors limiting individuals from donating, hemochromatosis patients are interested in being voluntary blood donors and this potential resource is currently under-used.

    2018-04-01

    Perforated peptic ulcer is one of the most common surgical emergencies worldwide. With the improvement in medical therapy for peptic ulcers, the number of elective surgical procedures has come down. However, the incidence of perforated peptic ulcer is still increasing and remains as a substantial health problem with significant postoperative morbidity and mortality. This study aimed to find out the association between various preoperative and intraoperative factors with the postoperative mortality and morbidity in patients operated for peptic ulcer perforation. This prospective observational study had a time based sample of 101 perforation peritonitis cases admitted to the surgical wards of a tertiary care center from February 2015 to January 2016 who underwent laparotomy, diagnosed to have peptic ulcer perforation and underwent simple closure with an omental patch. Data regarding age, gender, presenting complaints, time elapsed from the onset of symptoms to surgery, physical examination findings, comorbid diseases, laboratory and imaging findings, intraoperative findings, length of hospital stay, postoperative morbidity, and mortality were recorded and analyzed. Female gender, older age group, perforation surgery interval more than 36 h, and size of perforation more than 1 cm 2 were found to be significant factors influencing postoperative mortality and morbidity. Postoperative morbidity was also associated with comorbid diseases. Abnormal renal function on presentation was identified as an additional risk factor for postoperative morbidity and longer hospital stay. An understanding of these factors, identification of patients at risk and early intervention can help in reducing the postoperative morbidity and mortality in peptic ulcer perforation.

    Organised breast cancer screening is currently one of the best strategies for early-stage breast cancer detection. However, early detection has proven challenging for women with psychiatric disease. This study aims to investigate psychiatric morbidity and non-participation in breast cancer screening. We conducted an observational cohort study including women invited to the first organised screening round in the Central Denmark Region. Data on psychiatric diagnosis, psychoactive prescription medicine and consultation with private psychiatrists were obtained from Danish registries and assessed for a period of up to 10 years before the screening date. The cohort comprised 144,264 women whereof 33.0% were registered with an indication of psychiatric morbidity. We found elevated non-participation propensity among women with a psychiatric diagnosis especially for women with schizophrenia and substance abuse. Also milder psychiatric morbidity was associated with higher non-participation likelihood as women who had redeemed psychoactive prescription medicine or have had minimum one consultation with a private psychiatrist were more likely not to participate. Finally, we found that the chronicity of psychiatric morbidity was associated with non-participation and that woman who had a psychiatric morbidity defined as 'persistent' had higher likelihood of non-participation than women with recently active morbidity or inactive psychiatric morbidity. This study showed a strong association between psychiatric morbidity and an increased likelihood of non-participation in breast cancer screening in a health care system with universal and tax-funded health services. This knowledge may inform interventions targeting women with psychiatric morbidity as they have poorer breast cancer prognosis. Copyright © 2015 Elsevier Ltd. All rights reserved.

    To assess the influence of donor, environment, and logistical factors on the results of virological testing of blood samples from cornea donors.Data from 670 consecutive cornea donors were analyzed retrospectively. Logistic regression analysis was used to assess the influence of different factors on the results of virological testing of blood samples from cornea donors.The mean annual rate of donors with serology-reactive or not evaluable result was 14.8% (99 of 670) (range 11.9%-16.9%). The cause of donor death by cancer increased the risk of serology-reactive or not evaluable result (P = .0300). Prolonged time between death and post mortem blood removal was associated with a higher rate of serology-reactive or not evaluable result (P donors, sex, and donor age had no significant impact on the results of virological testing of blood samples from cornea donors.The cause of donor death by cancer and a prolonged time between death and post mortem blood removal seem to be mainly responsible for serology-reactive or not evaluable result of blood samples from cornea donors. The percentage of discarded corneas caused by serology-reactive or not evaluable result may be reduced by shortening the period of time between death and post mortem blood removal.

    2006-01-01

    The application of nuclear transfer technology is an interesting approach to investigate stem and progenitor cell transplantation therapy. If stem cells are used as a nuclear donor, donor cells can engraft into cloned animals without histocompatible problems. However, it is still uncertain whether donor cells can engraft to cloned animal and differentiate in vivo. To address this problem, we transplanted donor cells to dermal tissues of cloned pigs developed by using preadipocytes as donor cells. Preadipocytes are adipocytic progenitor which can differentiate to mature adipocytes in vitro. We showed that the donor preadipocytes were successfully transplanted into the cloned pigs without immune rejection and they differentiated into mature adipocytes in vivo 3 weeks after transplantation. In contrast, allogenic control preadipocytes, which can differentiate in vitro, did not differentiate in vivo. These results indicate that donor progenitor cells can differentiate in cloned animal

  14. Whole-blood donation: blood donor suitability and adverse events.

    2004-11-01

    Approximately 3% to 3.5% of the US population donates whole blood each year. Physicians might be approached by a blood donor because of a donor suitability issue, a positive postdonation test, or a donation-related complication. Approximately 83% of blood donors successfully donate; but 13% are rejected because of a donor suitability issue; 1% have a positive test, which is often nonspecific or false-positive; and 2% to 4% of the phlebotomies are not successful. The most common adverse physical events based on donor interviews are bruise (23%), sore arm (10%), fatigue (8%), and vasovagal reaction (7%), while uncommon events include nerve irritation (0.9%), syncope (0.1-0.3%), and arterial puncture (0.01%). One in 3400 donors (0.033%) report seeking outside medical care. Serious injuries occur but are very rare. More often, blood donors do well and feel satisfied with the blood donation experience.

    Endosseous dental implants may require bone augmentation before implant placement. Herein is described an approach to edentulous ridge expansion with the use of piezosurgery and immediate placement of implants. This may allow for a shortened treatment time and the elimination of donor-site morbidity. Two cases are reported. This technique uses a piezoelectric device to cut the crestal and proximal facial cortices. Space is then created with motorized osteotomes to widen the split ridge. This technique allows for expansion of narrow, anatomically limiting, atrophic ridges, creating space for immediate implant placement. The facial and lingual cortices provide support with vital osteocytes for osteogenesis. The 2 patients presented had adequate bone height for implant placement but narrow edentulous ridges. In patient 1 at site #11, the ridge crest was 3.12 mm thick and was expanded to accept a 4.3 mm × 13 mm implant. The resulting ridge width was 8.88 mm, which was verified using cone beam computerized tomography (CBCT). In patient 2 at site #8 and site #9, the narrow ridge was expanded using the same technique to accept 2 adjacent 3.5 mm × 14 mm implants. The implants were restored to a functional and esthetic outcome.

    The Retrovirus Epidemiology Donor Study (REDS), conducted from 1989–2001, and the Retrovirus Epidemiology Donor Study-II (REDS-II), conducted from 2004–2012, were National Heart Lung and Blood Institute (NHLBI) funded multicenter programs focused on improving blood safety and availability in the United States. REDS-II also included international study sites in Brazil and China. The three major research domains of REDS/REDS-II have been infectious disease risk evaluation, blood donation availability, and blood donor characterization. Both programs have made significant contributions to transfusion medicine research methodology by the use of mathematical modeling, large-scale donor surveys, innovative methods of repository sample storage, and establishing an infrastructure that responded to potential emerging blood safety threats such as XMRV. Blood safety studies have included protocols evaluating epidemiologic and/or laboratory aspects of HIV, HTLV I/II, HCV, HBV, WNV, CMV, HHV-8, B19V, malaria, CJD, influenza, and T. cruzi infections. Other analyses have characterized: blood donor demographics, motivations to donate, factors influencing donor return, behavioral risk factors, donors’ perception of the blood donation screening process, and aspects of donor deferral. In REDS-II, two large-scale blood donor protocols examined iron deficiency in donors and the prevalence of leukocyte antibodies. This review describes the major study results from over 150 peer-reviewed articles published by these two REDS programs. In 2011, a new seven year program, the Recipient Epidemiology and Donor Evaluation Study-III (REDS-III), was launched. REDS-III expands beyond donor-based research to include studies of blood transfusion recipients in the hospital setting, and adds a third country, South Africa, to the international program.

    Full Text Available Living donor liver donation (LDLD is an alternative to cadaveric liver donation. We aimed at identifying risk factors and developing a score for prediction of postoperative complications (POCs after LDLD in donors. This is a retrospective cohort study in 688 donors between June 1995 and February 2014 at Hospital Sírio-Libanês and A.C. Camargo Cancer Center, in São Paulo, Brazil. Primary outcome was POC graded ≥III according to the Clavien-Dindo classification. Left lateral segment (LLS, left lobe (LL, and right lobe resections (RL were conducted in 492 (71.4%, 109 (15.8%, and 87 (12.6% donors, respectively. In total, 43 (6.2% developed POCs, which were more common after RL than LLS and LL (14/87 (16.1% versus 23/492 (4.5% and 6/109 (5.5%, resp., p<0.001. Multivariate analysis showed that RL resection (OR: 2.81, 95% CI: 1.32 to 3.01; p=0.008, smoking status (OR: 3.2, 95% CI: 1.35 to 7.56; p=0.012, and blood transfusion (OR: 3.15, 95% CI: 1.45 to 6.84; p=0.004 were independently associated with POCs. RL resection, intraoperative blood transfusion, and smoking were associated with increased risk for POCs in donors.

    2016-05-20

    We designed anthracene bisimide (ABI) derivatives having two triphenylamine (TPA) groups as donor units at the 9,10-positions to form a novel π-conjugated donor-acceptor system. These compounds and their analogues with ethynylene linkers were synthesized by Suzuki-Miyaura and Sonogashira coupling reactions, respectively. In UV-vis spectra, the linker-free derivatives showed broad absorption bands arising from intramolecular charge-transfer interactions. Introducing ethynylene linkers resulted in a considerable red shift of the absorption bands. In fluorescence spectra, the ethynylene derivatives showed intense emission bands at 600-650 nm. Their photophysical and electrochemical properties were compared with those of the corresponding mono TPA derivatives on the basis of theoretical calculations and cyclic voltammetry to evaluate the intramolecular electronic interactions between the donor and acceptor units.

    This study sought to determine whether early referral from the emergency department (ED) would increase the number of organ donors and the number of organs transplanted per donor (OTPD). This is a retrospective cohort analysis of all patients referred to a single organ procurement organization for a period of 60 months. Patients referred for organ donation evaluation from the ED were more likely to become organ donors than patients referred from the intensive care unit (19.3% vs 5.2%, P organ donation from the ED is associated with an increased likelihood of organ recovery and with an increased number of OTPD.

    2018-06-01

    Whilst studies have examined the experiences of women who use clinic donors, to date there has been limited research investigating women's motivations and experiences of searching for a sperm donor online. A total of 429 women looking for a sperm donor on Pride Angel (a website that facilitates contact between donors and recipients) completed an online survey. Fifty-eight percent (249) saw advantages of obtaining donated sperm online with the most common advantage reported as being able to connect with and meet the donor (n = 50 (24%)). A third (n = 157 (37%)) of the participants gave disadvantages, the most common reported was encountering 'dishonest donors' (n = 63 (40%)). Most recipients (n = 181 (61%)) wanted the donor to be 'just a donor' (i.e. to provide sperm and have no further contact). Whilst it was important for recipients to know the identity of the donor, some did not see this as important for the child and thus the level of information that parents have about the donor, and that which the child has, can differ. Finding a donor online blurs the distinction between categories of 'anonymous', 'known' and 'identity release' donations. Whilst the survey had a large sample size, the representativeness of the sample is not known.

    2006-09-01

    The purpose of this study was to examine the association of smoking and nicotine dependence with psychiatric morbidity, controlling for the potential confounding effect of smoking on the relationship between the use of other substances and psychiatric morbidity. A sample of 290 adults were interviewed at a primary health centre (patients, 58%; patients' relatives, 34%; staff, 8%) to inquire about their tobacco, caffeine, alcohol, and illegal drug consumption. Psychiatric morbidity, defined by a score >6 on the General Health Questionnaire (GHQ-28), showed a strong direct association with nicotine dependence. The use of illegal drugs, but not of alcohol, was also strongly associated with psychiatric morbidity, after controlling for smoking. Both smoking and high nicotine dependence were also associated with use of caffeine, alcohol, cannabis and cocaine. High nicotine dependence may be considered as an expression of individual psychopathologic vulnerability. Tobacco may have a central facilitating role in the use of caffeine, alcohol, and illegal drug.

    We present the detailed study of the spin kinetics of the nitrogen (N) donor electrons in 6H SiC wafers grown by the Lely method and by the sublimation “sandwich method” (SSM) with a donor concentration of about 10{sup 17 }cm{sup −3} at T = 10–40 K. The donor electrons of the N donors substituting quasi-cubic “k1” and “k2” sites (N{sub k1,k2}) in both types of the samples revealed the similar temperature dependence of the spin-lattice relaxation rate (T{sub 1}{sup −1}), which was described by the direct one-phonon and two-phonon processes induced by the acoustic phonons proportional to T and to T{sup 9}, respectively. The character of the temperature dependence of the T{sub 1}{sup −1} for the donor electrons of N substituting hexagonal (“h”) site (N{sub h}) in both types of 6H SiC samples indicates that the donor electrons relax through the fast-relaxing centers by means of the cross-relaxation process. The observed enhancement of the phase memory relaxation rate (T{sub m}{sup −1}) with the temperature increase for the N{sub h} donors in both types of the samples, as well as for the N{sub k1,k2} donors in Lely grown 6H SiC, was explained by the growth of the free electron concentration with the temperature increase and their exchange scattering at the N donor centers. The observed significant shortening of the phase memory relaxation time T{sub m} for the N{sub k1,k2} donors in the SSM grown sample with the temperature lowering is caused by hopping motion of the electrons between the occupied and unoccupied states of the N donors at N{sub h} and N{sub k1,k2} sites. The impact of the N donor pairs, triads, distant donor pairs formed in n-type 6H SiC wafers on the spin relaxation times was discussed.

    Background Obsessive–compulsive disorder (OCD) is probably an etiologically heterogeneous condition. Many patients manifest other psychiatric syndromes. This study investigated the relationship between OCD and co-morbid conditions to identify subtypes. Method Seven hundred and six individuals with OCD were assessed in the OCD Collaborative Genetics Study (OCGS). Multi-level latent class analysis was conducted based on the presence of eight co-morbid psychiatric conditions [generalized anxiety disorder (GAD), major depression, panic disorder (PD), separation anxiety disorder (SAD), tics, mania, somatization disorders (Som) and grooming disorders (GrD)]. The relationship of the derived classes to specific clinical characteristics was investigated. Results Two and three classes of OCD syndromes emerge from the analyses. The two-class solution describes lesser and greater co-morbidity classes and the more descriptive three-class solution is characterized by: (1) an OCD simplex class, in which major depressive disorder (MDD) is the most frequent additional disorder; (2) an OCD co-morbid tic-related class, in which tics are prominent and affective syndromes are considerably rarer; and (3) an OCD co-morbid affective-related class in which PD and affective syndromes are highly represented. The OCD co-morbid tic-related class is predominantly male and characterized by high conscientiousness. The OCD co-morbid affective-related class is predominantly female, has a young age at onset, obsessive–compulsive personality disorder (OCPD) features, high scores on the ‘taboo’ factor of OCD symptoms, and low conscientiousness. Conclusions OCD can be classified into three classes based on co-morbidity. Membership within a class is differentially associated with other clinical characteristics. These classes, if replicated, should have important implications for research and clinical endeavors. PMID:19046474

  13. CRISPR-Mediated Integration of Large Gene Cassettes Using AAV Donor Vectors

    Full Text Available The CRISPR/Cas9 system has recently been shown to facilitate high levels of precise genome editing using adeno-associated viral (AAV vectors to serve as donor template DNA during homologous recombination (HR. However, the maximum AAV packaging capacity of ∼4.5 kb limits the donor size. Here, we overcome this constraint by showing that two co-transduced AAV vectors can serve as donors during consecutive HR events for the integration of large transgenes. Importantly, the method involves a single-step procedure applicable to primary cells with relevance to therapeutic genome editing. We use the methodology in primary human T cells and CD34+ hematopoietic stem and progenitor cells to site-specifically integrate an expression cassette that, as a single donor vector, would otherwise amount to a total of 6.5 kb. This approach now provides an efficient way to integrate large transgene cassettes into the genomes of primary human cells using HR-mediated genome editing with AAV vectors.

    Substitutional donor atoms in silicon are promising qubits for quantum computation with extremely long relaxation and dephasing times demonstrated. One of the critical challenges of scaling these systems is determining inter-donor distances to achieve controllable wavefunction overlap while at the same time performing high fidelity spin readout on each qubit. Here we achieve such a device by means of scanning tunnelling microscopy lithography. We measure anti-correlated spin states between two donor-based spin qubits in silicon separated by 16 ± 1 nm. By utilising an asymmetric system with two phosphorus donors at one qubit site and one on the other (2P-1P), we demonstrate that the exchange interaction can be turned on and off via electrical control of two in-plane phosphorus doped detuning gates. We determine the tunnel coupling between the 2P-1P system to be 200 MHz and provide a roadmap for the observation of two-electron coherent exchange oscillations.

    We sought to determine the impact of (1) grade of the colon injury, (2) the formation of an ostomy, and (3) associated injuries on outcomes such as morbidity and mortality after blunt colon injuries. We retrospectively reviewed 16,814 cases of blunt abdominal trauma. Patients with colonic injuries were selected and charts reviewed for demographic, clinical, and outcomes data. Injuries were grouped by the Colon Injury Scale (grades I-V). Independent risk factors of morbidity included spine and lung injuries, as well as increased age. A higher grade of colon injury trended toward a significant association with intra-abdominal complications. Independent risk factors of mortality included liver, heart, and lung injuries, as well as intracerebral blood and female gender. The grade of colon injury, the formation of an ostomy, and management of the colon trauma did not independently predict increased intra-abdominal complications, morbidity, or mortality. These results indicate that patients afflicted with blunt colon trauma experience a high rate of morbidity and mortality from associated injuries and or increased age. Treatment regimens directed at these factors will be most helpful in reducing the high morbidity and mortality after blunt colon trauma. Factors such as ostomy formation and management strategy are not associated with increased morbidity or mortality after blunt colon trauma.

    Interventions to increase physical activity in pregnancy are challenging for morbidly obese women. Targeting sedentary behaviours may be a suitable alternative to increase energy expenditure. We aimed to determine total energy expenditure, and energy expended in sedentary activities in morbidly obese and lean pregnant women. We administered the Pregnancy Physical Activity Questionnaire PPAQ (non-objective) and the Actical accelerometer (objective) to morbidly obese (BMI≥40kg/m²) and lean (BMI≤25Kg/M²) pregnant women recruited in early (lean pregnant women. No differences were observed in the proportion of energy expended sedentary between lean and morbidly obese pregnant women. The greater total energy expenditure in morbidly obese pregnant women was corroborated by Actical accelerometer in early (n=14 per group, obese 1167.7 (313.6) Kcal; lean 781.1 (210.1) Kcal, plean 893.7 (175.9) Kcal, plean pregnant. Further studies are needed to determine whether sedentary behaviours are a suitable target for intervention in morbidly obese pregnancy. This article is protected by copyright. All rights reserved.

    The treatment of morbidly obese patients in orthopedic trauma differs in many ways compared to injured patients with normal body mass indices. This paper highlights key differences and ways to overcome obstacles. We present specific tips, as well as considerations for initial planning, positioning for surgery, intra-operative strategies, and a discussion on both anesthesia and imaging. Several treatment strategies have been shown to have better results in morbidly obese patients. Pre-operative planning is necessary for minimizing risk to the patient. The prevalence of morbid obesity has increased in the USA in the past quarter century. Treatment for orthopedic injuries in morbidly obese patients requires a multidisciplinary approach that addresses not only their orthopedic injuries, but also medical co-morbidities. A team of medicine doctors, anesthesiologists, X-ray technicians, physical and occupational therapists, respiratory therapists, and social workers is needed in addition to the orthopedic surgeon. Modifications in both pre-operative planning and intra-operative strategies may be necessary in order to accommodate the patient. This paper presents numerous technical tips that can aid in providing stable fixation for fractures, as well as addressing peri-operative issues specific to the morbidly obese.

    The demand for donor organs continues to exceed the number of organs available for transplantation. Many reasons may account for this discrepancy, such as the lack of consent, the absence of an experienced coordinator team able to solve logistical problems, the use of strict donor criteria, and suboptimal, unstandardized critical care management of potential organ donors. This has resulted in efforts to improve the medical care delivered to potential organ donors, so as to reduce organ shortages, improve organ procurement, and promote graft survival. The physiological changes that follow brain death entail a high incidence of complications jeopardizing potentially transplantable organs. Adverse events include cardiovascular changes, endocrine and metabolic disturbances, and disruption of internal homeostasis. Brain death also upregulates the release of pro-inflammatory molecules. Recent findings support the hypothesis that a preclinical lung injury characterized by an enhanced inflammatory response is present in potential donors and may predispose recipients to an adverse clinical prognosis following lung transplantation. In clinical practice, hypotension, diabetes insipidus, relative hypothermia, and natremia are more common than disseminated intravascular coagulation, cardiac arrhythmias, pulmonary oedema, acute lung injury, and metabolic acidosis. Strategies for the management of organ donors exist and consist of the normalization of donor physiology. Management has been complicated by the recent use of ''marginal'' donors and donors of advanced age or with ''extended'' criteria. Current guidelines suggest that the priority of critical care management for potential organ donors should be shifted from a ''cerebral protective'' strategy to a multimodal strategy aimed to preserve peripheral organ function.

  19. Q-FISH measurement of hepatocyte telomere lengths in donor liver and graft after pediatric living-donor liver transplantation: donor age affects telomere length sustainability.

    Directory of Open Access Journals (Sweden)

    Youichi Kawano

    Full Text Available Along with the increasing need for living-donor liver transplantation (LDLT, the issue of organ shortage has become a serious problem. Therefore, the use of organs from elderly donors has been increasing. While the short-term results of LDLT have greatly improved, problems affecting the long-term outcome of transplant patients remain unsolved. Furthermore, since contradictory data have been reported with regard to the relationship between donor age and LT/LDLT outcome, the question of whether the use of elderly donors influences the long-term outcome of a graft after LT/LDLT remains unsettled. To address whether hepatocyte telomere length reflects the outcome of LDLT, we analyzed the telomere lengths of hepatocytes in informative biopsy samples from 12 paired donors and recipients (grafts of pediatric LDLT more than 5 years after adult-to-child LDLT because of primary biliary atresia, using quantitative fluorescence in situ hybridization (Q-FISH. The telomere lengths in the paired samples showed a robust relationship between the donor and grafted hepatocytes (r = 0.765, p = 0.0038, demonstrating the feasibility of our Q-FISH method for cell-specific evaluation. While 8 pairs showed no significant difference between the telomere lengths for the donor and the recipient, the other 4 pairs showed significantly shorter telomeres in the recipient than in the donor. Multiple regression analysis revealed that the donors in the latter group were older than those in the former (p = 0.001. Despite the small number of subjects, this pilot study indicates that donor age is a crucial factor affecting telomere length sustainability in hepatocytes after pediatric LDLT, and that the telomeres in grafted livers may be elongated somewhat longer when the grafts are immunologically well controlled.

    This work investigates the influence of fluorination of both donor and acceptor materials on the generation of free charge carriers in small molecule donor/fullerene acceptor BHJ OPV active layers. A fluorinated and non-fluorinated small molecule analogue were synthesized and their optoelectronic properties characterized. The intrinsic photoconductance of blends of these small molecule donors was investigated using time-resolved microwave conductivity. Blends of the two donor molecules with a traditional non-fluorinated fullerene (PC70BM) as well as a fluorinated fullerene (C60(CF3)2-1) were investigated using 5% and 50% fullerene loading. We demonstrate for the first time that photoconductance in a 50:50 donor:acceptor BHJ blend using a fluorinated fullerene can actually be improved relative to a traditional non-fluorinated fullerene by fluorinating the donor molecule as well.

  4. Donor level of interstitial hydrogen in GaAs

    The first data evidencing the existence of the donor level of the interstitial hydrogen in GaAs are presented. The abundant formation of the (0/+) donor level after in situ low-temperature implantation of hydrogen into the depletion layer of GaAs Schottky diodes has been observed and the activation energy and annealing properties have been determined by Laplace DLTS. The activation energy for electron emission of this donor state is 0.14eV. Above 100K the hydrogen deep donor state is unstable, converting to a more stable form when there are electrons available for the capture process. A slightly perturbed form of the hydrogen donor in its neutral charge state can be recovered by illuminating the sample. This process releases twice as many electrons as the ionisation process of the hydrogen donor state itself. This fact, by analogy with the silicon case, evidences the negative-U behaviour of hydrogen in GaAs

  5. Brush Polymer of Donor-Accepter Dyads via Adduct Formation between Lewis Base Polymer Donor and All Carbon Lewis Acid Acceptor

    Directory of Open Access Journals (Sweden)

    2017-09-01

    Full Text Available A synthetic method that taps into the facile Lewis base (LB→Lewis acid (LA adduct forming reaction between the semiconducting polymeric LB and all carbon LA C60 for the construction of covalently linked donor-acceptor dyads and brush polymer of dyads is reported. The polymeric LB is built on poly(3-hexylthiophene (P3HT macromers containing either an alkyl or vinyl imidazolium end group that can be readily converted into the N-heterocyclic carbene (NHC LB site, while the brush polymer architecture is conveniently constructed via radical polymerization of the macromer P3HT with the vinyl imidazolium chain end. Simply mixing of such donor polymeric LB with C60 rapidly creates linked P3HT-C60 dyads and brush polymer of dyads in which C60 is covalently linked to the NHC junction connecting the vinyl polymer main chain and the brush P3HT side chains. Thermal behaviors, electronic absorption and emission properties of the resulting P3HT-C60 dyads and brush polymer of dyads have been investigated. The results show that a change of the topology of the P3HT-C60 dyad from linear to brush architecture enhances the crystallinity and Tm of the P3HT domain and, along with other findings, they indicate that the brush polymer architecture of donor-acceptor domains provides a promising approach to improve performances of polymer-based solar cells.

    Deterministic control over the location and number of donors is critical for donor spin qubits in semiconductor based quantum computing. We have developed techniques using a focused ion beam and a diode detector integrated next to a silicon MOS single electron transistor to gain such control. With the diode detector operating in linear mode, the numbers of ions implanted have been counted and single ion implants have been detected. Poisson statistics in the number of ions implanted have been observed. Transport measurements performed on samples with counted number of implants have been performed and regular coulomb blockade and charge offsets observed. The capacitances to various gates are found to be in agreement with QCAD simulations for an electrostatically defined dot. This work was performed, in part, at the Center for Integrated Nanotechnologies, a U.S. DOE Office of Basic Energy Sciences user facility.

    Culture, society and spirituality contribute to variability in the characteristics of human body donors and donation programmes worldwide. The donors and the body donation programme at Khon Kaen University, northeast Thailand, reflect all these aspects of Thailand, including the status accorded to the donors and the ceremonial acknowledgement of the donors and their families. Data from the programme records and from surveys of samples of currently registering donors and recently received donor bodies are analysed to define the characteristics of both registering and received donors, including motivation, demography, socio-economic status, health, and use of the bodies. The body donation programme at Khon Kaen University currently has a very high rate of registration of body donors, with gender and age differences in the patterns of donation. Registrants include more females than males, a long-standing pattern, and are an average age of 50 years. The bodies of 12% of registrants are received after death and include more males than females. Both sexes are of an average age of 69 years. Males had registered their donation eight years prior to death and females ten years prior. Current registrants identified altruistic motives for their decision to donate, although the coincidence of body donation by a highly revered monk with a surge in donations in 2015 suggests that Buddhism plays a primary role in motivation. The opportunity to make merit for donors and their families, and respect shown to donors and the nature of the ceremonies acknowledging the donors and their families, including the use of the Royal Flame at the cremation ceremony, all contribute to decisions to donate. The characteristics of body donors and the body donation programme at Khon Kaen University are reflective of Thai society and the centrality of Buddhism to Thai culture.

    1996-12-01

    The insufficient number of kidney transplants has gradually raised the age limit to the cadaver kidney donor. The use of grafts harvested from older donors has been debated due to the existing structural and functional changes that might influence renal function and long-term graft survival. The foregoing aspects are discussed herein. The anatomical, histological and functional changes in the kidney associated with ageing are analyzed. The clinical experience with renal grafts from older donors before and after cyclosporine became available are reviewed. The ethical issues on whether grafts from very old donors should be used and who should receive these grafts are discussed. The use of grafts from donors over 60 years old had no significant short and medium term differences in comparison with younger donors in terms of graft survival, although a higher incidence of acute tubular necrosis and poor renal function have been observed. There are no conclusive studies on the long-term effects on graft survival when kidneys from donors aged over 65 are utilized. In our experience, the results achieved with grafts from donors over 70 has been unsatisfactory. The guidelines utilized in the selection of grafts derived from older donors are presented. Grafts from donors aged 60 to 70 may be utilized in renal transplantation following precise selection criteria. Graft survival has been satisfactory, although a higher incidence of acute tubular necrosis and higher creatinine levels have been observed. We do not advocate the use of grafts from donors over 70, except in very exceptional cases. Long-term multicenter studies on grafts from very old donors and trials using alternative immunosuppressor modalities that might permit optimal use of these grafts are warranted.

    Psychological stress has been shown to be an influential factor on the rate of wound healing; however these findings have been demonstrated predominantly on artificially created wounds. Due to the absence of major co-morbidities, living kidney donors are a unique group in which to study this relationship. This study investigated the effect of preoperative stress and personality on surgical wound healing through the use of high-resolution ultrasound. Living kidney donors due to undergo a hand-assisted laparoscopic donor nephrectomy were asked to complete the Perceived Stress Scale, the Life Orientation Test-Revised and the Ten Item Personality Inventory prior to surgery. High-resolution ultrasound scans of surgical wounds were performed on the first three post-operative days and once following discharge (mean=15.3 days; s.d. 2.8). Two measurements from each image were obtained: wound width (size of wound) and median intensity (a marker of tissue fluid). Latent Growth Curve Models (LGCMs) were used to evaluate wound healing. 52 living kidney donors participated. Higher pre-operative life stress, lower optimism and lower conscientiousness were associated with delayed wound healing in living kidney donors for both outcomes. Increased emotional stability was associated with faster wound healing as demonstrated by a change in median intensity. Possible confounding factors, such as age, BMI, smoking status, local anaesthetic use and wound drain placement were not influential. This study, which measured wound healing in a novel patient sample using a novel technique, has demonstrated a negative association between stress and wound healing and the positive influence of optimism, conscientiousness and emotional stability.

    Comparison of cultured skin substitutes (CSS) and split-thickness skin autograft (AG) was performed to assess whether donor-site harvesting can be reduced quantitatively and whether functional and cosmetic outcome is similar qualitatively in the treatment of patients with massive cutaneous burns. Cultured skin substitutes consisting of collagen-glycosaminoglycan substrates populated with autologous fibroblasts and keratinocytes have been shown to close full-thickness skin wounds in preclinical and clinical studies with acceptable functional and cosmetic results. Qualitative outcome was compared between CSS and AG in 45 patients on an ordinal scale (0, worst; 10, best) with primary analyses at postoperative day 28 and after about 1 year for erythema, pigmentation, pliability, raised scar, epithelial blistering, and surface texture. In the latest 12 of the 45 patients, tracings were performed of donor skin biopsies and wounds treated with CSS at postoperative days 14 and 28 to calculate percentage engraftment, the ratio of closed wound:donor skin areas, and the percentage of total body surface area closed with CSS. Measures of qualitative outcome of CSS or AG were not different statistically at 1 year after grafting. Engraftment at postoperative day 14 exceeded 75% in the 12 patients evaluated. The ratio of closed wound:donor skin areas for CSS at postoperative day 28 was significantly greater than for conventional 4:1 meshed autografts. The percentage of total body surface area closed with CSS at postoperative day 28 was significantly less than with AG. The requirement for harvesting of donor skin for CSS was less than for conventional skin autografts. These results suggest that acute-phase recovery of patients with extensive burns is facilitated and that complications are reduced by the use of CSS together with conventional skin grafting.

  12. Chance of psychiatric morbidity amongst recently diagnosed cancer outpatients attending a chemotherapy unit

    Full Text Available The prevalent rate of psychiatry morbidity amongst patients with cancer reported in various studies ranges from 5 to 50%, a variation that can be attributed to differences in sample size, the disease itself and treatment factors. The objectives of the present study were to determine the frequency of psychiatric morbidity amongst recently diagnosed cancer outpatients and try to identify which factors might be related to further psychological distress. Two hundred and eleven (70.9% female patients and 87 (29.1% male patients from the chemotherapy unit of the Cancer Hospital A.C. Camargo (São Paulo completed a questionnaire that featured data on demographic, medical and treatment details. The Self Reporting Questionnaire (SRQ-20 was administered to the patients to determine their personal psychiatric morbidity. Seventy-two patients (25.8% scored > or = 8 in the SRQ-20, the cut-off point for a patient to be considered a psychiatric case. When the low and high scoring groups were compared no differences were detected regarding age, marital status, tumor site, sex, or previous treatment. Nonetheless, patients in the lowest social class and those who were bedridden less than 50% of the time had a significantly higher probability of being a psychiatric case. Regarding help-seeking behavior in situations in which they had doubts or were frightened, about 64% of the total sample did not seek any type of support and did not talk to anyone. This frequency of psychiatric morbidity agrees with data from the cancer literature. According to many investigators, the early detection of a comorbid psychiatric disorder is crucial to relieve a patient's suffering.

Methods and Materials: Children treated with protons at Loma Linda University Medical Center between August 1991 and December 1994 were analyzed retrospectively. Twenty-eight children, aged 1 to 18 years, were identified as at risk for brain injury from treatment. Medical records, physical examinations, and correspondence with patients, their parents, and referring physicians were analyzed. The investigators tabulated post-treatment changes in pre-treatment signs and symptoms and made judgments as to whether improvement, no change, or worsening related to disease or treatment had supervened. Magnetic resonance images were correlated with clinical findings and radiographic impressions were tabulated. Results: Follow-up ranged from 7 to 49 months (median 25 months). Four instances of treatment-related morbidity were identified. Forty-one instances of site-specific, disease-related morbidity were identified: 15 improved or resolved and 26 remained unchanged after treatment. Four patients had radiographic evidence of local failure. Three of these patients, including two with high-grade glioma, have died. Conclusion: Early treatment-related morbidity associated with proton therapy is low. Tumor progression remains a problem when treating certain histologies such as high-grade glioma. Escalating the dose delivered to target volumes may benefit children with tumors associated with poor rates of local control. Long-term follow-up, including neurocognitive testing, is in progress to assess integral-dose effects on cognitive, behavioral and developmental outcomes in children with cranial tumors

    Background Recently, it has been assumed that resistance of Plasmodium to chloroquine increased malaria mortality. The study aimed to assess the impact of chemoresistance on mortality attributable to malaria in a rural area of Senegal, since the emergence of resistance in 1992, whilst chloroquine was used as first-line treatment of malaria, until the change in national anti-malarial policy in 2003. Methods The retrospective study took place in the demographic surveillance site (DSS) of Niakhar. Data about malaria morbidity were obtained from health records of three health care facilities, where diagnosis of malaria was based on clinical signs. Source of data concerning malaria mortality were verbal autopsies performed by trained fieldworkers and examined by physicians who identified the probable cause of death. Results From 1992 to 2004, clinical malaria morbidity represented 39% of total morbidity in health centres. Mean malaria mortality was 2.4‰ and 10.4‰ among total population and children younger than five years, respectively, and was highest in the 1992-1995 period. It tended to decline from 1992 to 2003 (Trend test, total population p = 0.03, children 0-4 years p = 0.12 - children 1-4 years p = 0.04- children 5-9 years p = 0.01). Conclusion Contrary to what has been observed until 1995, mortality attributable to malaria did not continue to increase dramatically in spite of the growing resistance to chloroquine and its use as first-line treatment until 2003. Malaria morbidity and mortality followed parallel trends and rather fluctuated accordingly to rainfall. PMID:19943921

    Full Text Available Purpose: The purpose of this study was to evaluate the serological profile of the eye donors and to study the influence of various factors on serological test results. Methods: A cross-sectional, observational study was conducted, and data of 509 donors were reviewed from the records of eye bank from December 2012 to June 2017. Various details of donors analyzed included the age, sex of the donor, cause of death, source of tissue, time since blood collection after death, macroscopic appearance of blood sample, and details of discarded tissues. Serological examination of blood was performed for human immunodeficiency virus (HIV, hepatitis B virus, hepatitis C virus (HCV, venereal disease research laboratory (VDRL, and serology reports reactive or nonreactive were analyzed. Results: Among the 509 donors, 295 (58% were male, and 420 (82.50% belonged to age group ≥60 years. Most donors (354, 69.5% died due to cardiac arrest. Macroscopically, sera were normal in the majority of 488 (95.9% cases. Among 509 donors, 475 (93.3% were nonreactive, 12 (2.4% donors were found to be reactive to hepatitis B surface antigen (HBsAg, and 1 (0.2% was reactive to HCV, but no donor serology was reactive to HIV or VDRL. Twenty-one (4.12% donors' sera were not fit for serological testing. Among all donors, 475 (93.32% donors were accepted and 34 (6.67% were rejected or discarded on the basis of serological testing. Cause of death and macroscopic aspect of sera influenced the serological results in a highly significant manner (P = 0.00. Acceptance or rejection of the donor was significantly influenced by the serological results of the donor (P = 0.00. Conclusion: The seroprevalence among eye donor for HBsAg and HCV was 12 (2.4% and 1 (0.2%, respectively. Factors such as cause of death and macroscopic aspect of sera influence the serological results. Time since blood collection or sampling will not show any impact on viral serological results if postmortem sampling

    Management of organ donors in the intensive care unit is an emerging subject in critical care and transplantation. This study evaluates organ yield outcomes for a large number of patients managed by the Indiana Organ Procurement Organization. This is a retrospective review of intensive care unit records from 2008-2012. Donor demographic information and seven donor management parameters (DMP) were recorded at admission, consent, 12 h after consent, and before procurement. Three study groups were created: donors meeting 0-3, 4, or 5-7 DMP. Active donor Organ Procurement Organization management began at consent; so, data analysis focuses on the 12-h postconsent time point. Outcomes included organs transplanted per donor (OTPD) and transplantation of individual solid organs. Complete records for 499 patients were reviewed. Organ yield was 1415 organs of 3992 possible (35%). At 12 h, donors meeting more DMP had more OTPD: 2.2 (0-3) versus 3.0 (4) versus 3.5 (5-7) (P organ except intestine. Oxygen tension, vasopressor use, and central venous pressure were the most frequent independent predictors of organ usage. There were significantly more organs transplanted for donors meeting all three of these parameters (4.5 versus 2.7, P organs, with analysis of individual parameters suggesting that appropriate management of oxygenation, volume status, and vasopressor use could lead to more organs procured per donor.

    Rhabdomyolysis in deceased donors usually causes acute renal failure (ARF), which may be considered a contraindication for kidney transplantation. From January 2012 to December 2016, 30 kidneys from 15 deceased donors with severe rhabdomyolysis and ARF were accepted for transplantation at our center. The peak serum creatinine (SCr) kinase, myoglobin, and SCr of the these donors were 15 569±8597 U/L, 37 092±42 100 μg/L, and 422±167 μmol/L, respectively. Two donors received continuous renal replacement therapy due to anuria. Six kidneys exhibited a discolored appearance (from brown to glossy black) due to myoglobin casts. The kidney transplant results from the donors with rhabdomyolysis donors were compared with those of 90 renal grafts from standard criteria donors (SCD). The estimated glomerular filtration rate at 2 years was similar between kidney transplants from donors with rhabdomyolysis and SCD (70.3±14.6 mL/min/1.73 m 2 vs 72.3±15.1 mL/min/1.73 m 2 ). We conclude that excellent graft function can be achieved from kidneys donors with ARF caused by rhabdomyolysis. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Expanding the use of elderly live donors may help meet the demand for kidney transplants. The aim of this study was to quantify the effect of the surgical procedure on the quality of life (QOL) of elderly donors compared with younger donors. Alongside three prospective studies (two randomized) running between May 2001 and October 2010, we asked 501 live donors to fill out the Short Form-36 questionnaire preoperatively and at 1, 3, 6, and 12 months postoperatively. We defined live donors 60 years or older as elderly. Between-group analyses regarding QOL were adjusted for baseline values and gender. One hundred thirty-five donors were older and 366 donors were younger than 60 years. The response rate was high, with 87% at 12 months postoperatively. Elderly donors less often scored as American Society of Anaesthesiology classification 1 (60% vs. 81%; Pvitality" (5 points; P=0.008). At 3 months, "bodily pain" (3 points, P=0.04) and "role physical" (8 points, P=0.02) were still in favor of the older group. At 6 and 12 months, "physical function" was in favor of the younger group (3 and 5 points, respectively; P=0.04 and P<0.001). This study demonstrates that elderly donors recover relatively fast. The perspective of excellent postoperative QOL may help convince elderly individuals to donate.

    To review the vascular anatomy of the donor and the recipient for the living kidney transplantation. The recent literature about the vessels of donor and recipient in clinical applications was extensively reviewed. The pertinent vascular anatomy of the donor and recipient was essential for the screening of the proper candidates, surgical planning and long-term outcome. Early branching and accessory renal artery of the donor were particularly important to deciding the side of nephrectomy, surgical technique and anastomosing pattern, and their injuries were the most frequent factor of the conversion from laparoscopic to open surgery. With increase of laparoscopic nephrectomy in donors, accurate venous anatomy was paid more and more attention to because venous bleeding could also lead to conversion to open nephrectomy. Multidetector CT (MDCT) could supplant the conventional excretory urography and renal catheter angiography and could accurately depict the donors' vessels, vascular variations. In addition, MDCT can excellently evaluate the status of donor kidney, collecting system and other pertinent anatomy details. Accurate master of related vascular anatomy can facilitate operation plan and success of operation and can contribute to the rapid development of living donor kidney transplantation. MDCT has become the choice of preoperative one-stop image assessment for living renal donors.

    Embryo donation produces a family structure where neither rearing parent is genetically related to the child, as in adoption. It is not known how embryo donation parents view the donors compared with how adoptive parents view the birth parents. 21 couples with an embryo donation child aged 2-5 years were compared with 28 couples with an adopted child. Parents were administered a semi-structured interview, assessing knowledge of the donors/birth parents, frequency of thoughts and discussions about the donors/birth parents and disclosure of the donor conception/adoption to the child. Comparisons were made between mothers and fathers to examine gender differences. Embryo donation parents generally knew only the donors' physical characteristics, and thought about and talked about the donors less frequently than adoptive parents thought about and talked about the birth parents. Embryo donation fathers tended to think about the donors less often than did mothers. Disclosure of the child's origins in embryo donation families was far less common than in adoptive families (P parents' views on the donors differ from adoptive parents' views on the birth parents, with donors having little significance in family life once treatment is successful.

    The postpartum period is under-researched in low and middle income countries. The scarce literature reveals heavy burden of ill health experienced in that period and under utilisation of health services. Understanding the postpartum morbidity burden and identifying the care-seeking behaviours is essential to improve service delivery. This paper examines reported postpartum morbidity, care seeking behaviour and whether postpartum morbidity is associated with method of birth. A cross sectional study of women delivering in 18 private hospitals from two regions in Lebanon was undertaken. Women in their second or third trimester of pregnancy, visiting private obstetric clinics affiliated with participating hospitals were interviewed for baseline information. Reported postpartum morbidity was assessed in an interview conducted at women's homes from 40 days up to six months postpartum. Of the 269 women recruited, physical postpartum health problems were reported by 93.6% and psychological health problems by 84.4% of women, with more health problems being reported beyond two months postpartum. Women were less likely to seek professional care for psychological health problems. Reporting postpartum health problems was not associated with method of birth. A heavy burden of postpartum morbidity is experienced by women with gaps in utilisation of relevant health services. Efforts should be directed towards the organisation and delivery of comprehensive maternity care services. Copyright © 2013 Australian College of Midwives. Published by Elsevier Ltd.

    Professional education can be a stressful experience for some individuals, and may impact negatively on emotional well-being and academic performance. Psychological morbidity and associated sources of stress have not been investigated extensively in physiotherapy students. This study explored sources of stress, psychological morbidity and possible associations between these variables in undergraduate physiotherapy students. A questionnaire-based survey. The Undergraduate Sources of Stress Questionnaire was used to identify sources of stress, and the General Health Questionnaire-12 (GHQ-12) was used to rate the prevalence of psychological morbidity, using a conservative GHQ threshold of 3 to 4 to determine probable 'cases'. Uni- and multivariate tests of correlation were used to analyse the data. An Irish educational institution. One hundred and twenty-five physiotherapy undergraduate students. More than one-quarter of all students (27%) scored above the GHQ threshold, indicating probable psychological morbidity. This is higher than the level of psychological morbidity reported by the general population. Regression analysis showed that academic (beta=0.31, Pphysiotherapy students, with academic and personal issues being the greatest concern. While personal causes of stress such as stressful events and mood are more difficult to control, manipulation of curricular factors may have positive effects on academic sources of stress.

    To what extent psychiatric morbidity and personality factors contribute to marital disharmony and decision to divorce is still an unanswered question in Indian setting. This study was undertaken with aims to find out (1) the prevalence of psychiatric morbidity in persons seeking divorce; (2) the prevalence of psychiatric morbidity in persons who had good marital adjustment; (3) the nature of psychiatric morbidity observed in these subjects, and (4) the personality profile of these subjects. Fifty randomly selected divorce seeking couples (n=100) from the matrimonial court of Jaipur City and thirty couples with good marital adjustment (n=60) selected from the community were studied. Probable psychiatric cases identified by administering GHQ (Hindi version) were diagnosed according to ICD-10 and personality profile of all cases was studied by using 16 PF. High psychiatric morbidity (50%) was found among divorce seeking couples in comparison to control group (13%). There was a high prevalence of neurone disorders (22%) and mood disorders (16%) in experimental group. Schizophrenia and related disorders (10%) and substance abuse disorder (2%) were seen only in the experimental group. Specific personality factors related to divorce seeking individuals and persons with stable marriage have been identified. The implications of this study are highlighted. PMID:21743746

    The demand for liver transplantation has increasingly exceeded the supply of cadaver donor organs. Non-heart-beating donors (NHBDs) may be an alternative to increase the cadaver donor pool. The outcome of 20 liver transplants from Maastricht category 2 NHBD was compared with that of 40 liver transplants from heart-beating donors (HBDs). After unsuccessful cardiopulmonary resuscitation (CPR), cardiopulmonary support with simultaneous application of chest and abdominal compression (CPS; n = 6) or cardiopulmonary bypass (CPB; n = 14) was used to maintain the donors. At a minimum follow-up of 2 years, actuarial patient and graft survival rates with livers from Maastricht category 2 NHBD were 80% and 55%, respectively. Transplantation of organs from these donors was associated with a significantly higher incidence of primary nonfunction, biliary complications, and more severe initial liver dysfunction compared with organs from HBDs. The graft survival rates was 83% for livers from NHBDs preserved with CPS and 42% in those maintained with CPB.

    Postoperative bloodstream infection (BSI) is the most important determinant of recipient morbidity and mortality after liver transplantation (LT). Children who underwent LT are at the highest risk of developing BSI because of the significant surgical intervention, use of multiple devices, and administration of immunosuppressive agents. However, information regarding the risk factors for BSI in children after LT is limited. We retrospectively reviewed 210 children who underwent living-donor LT at the largest pediatric LT center in Japan. Patients' characteristics, blood culture results and clinical outcomes were extracted from electronic medical records. Univariate and multivariate analyses were performed to identify the risk factors for BSI. Among the 210 LT recipients, 53 (25%) recipients experienced 86 episodes of BSI during the observational period. The source of the BSI was identified only in 38%: catheter-related BSI (27%) peritonitis (7%), urinary tract infection (2%), pneumonia (1%) and infectious endocarditis (1%). A multivariate analysis demonstrated that body weight (P = 0.03), volume of blood loss during LT (P 24 months), blood loss and pediatric end-stage liver disease/model for end-stage liver disease versus positive CMV antigenemia. The volume of blood loss, postoperative CMV antigenemia positivity and body weight were associated with the development of BSI after LT in pediatric living-donor recipients. To identify the age-specific predictors of BSI in children who underwent LT, age-specific analyses are crucial.

    Treatment of healthy donors with recombinant human granulocyte colony-stimulating factor (rhG-CSF) allows the mobilization and peripheralization into circulating blood of an adequate number of CD34+ cells that can then be collected by leukapheresis (PBSC). This procedure avoids the invasiveness of bone marrow harvest and the risks related to general anesthesia. The main adverse effects of rhG-CSF are: bone pain, 84%, headache, 54%, fatigue, 31%, and nausea, 13%, which are usually scored by the donors as moderate to severe, resolving within 2-3 days after discontinuation of the cytokine. Analgesics, mainly acetaminophen, are sufficient to control the pain. Less than 5% of the donors experience non-cardiac chest pain, a local reaction at the injection site, insomnia, dizziness or a low-grade fever. Discontinuation of the PBSC procedure because of adverse effects of rhG-CSF or leukapheresis is rarely necessary (0.5%) but this good tolerability can be hampered by the need, in 5-20% of cases, for an adequate venous access that requires insertion of a central or venous catheter. There are no absolute contraindications to the stimulation of healthy donors with rhG-CSF but the description of cases of non-traumatic splenic rupture, iritis, cardiac ischemia, and gouty arthritis suggests that further precautionary restrictions are advisable when deciding eligibility for PBSC collection. The main advantages for patients receiving an allogeneic PBSC transplant are the faster hematologic and immunologic recovery and the potential for a greater efficacy in advanced disease by lowering the transplant-related mortality. One of the major concerns regarding the use of rhG-CSF in unrelated healthy donors is the uncertainty about its possible role in triggering malignancy, in particular myelodysplastic syndrome and acute myeloid leukemia. There are no studies with an adequate sample size and follow-up that can answer this question but two recent retrospective studies reported that in

    Background The ageing population and recent migration flows may negatively affect the blood supply in the long term, increasing the importance of targeted recruitment and retention strategies to address donors. This review sought to identify individual, network and contextual characteristics related to blood donor status and behaviour, to systematically discuss differences between study results, and to identify possible factors to target in recruitment and retention efforts. Methods The systematic review was conducted in accordance with a predefined PROSPERO protocol (CRD42016039591). After quality assessments by multiple independent raters, a final set of 66 peer-reviewed papers, published between October 2009 and January 2017, were included for review. Results Individual and contextual characteristics of blood donor status and behaviour were categorised into five main lines of research: donor demographics, motivations and barriers, adverse reactions and deferral, contextual factors, and blood centre factors. Results on donor demographics, motivations and barriers, and contextual factors were inconclusive, differing between studies, countries, and sample characteristics. Adverse reactions and deferral were negatively related to blood donor behaviour. Blood centre factors play an important role in donor management, e.g., providing information, reminders, and (non-)monetary rewards. No studies were found on network characteristics of (non-)donors. Discussion Although individual and contextual characteristics strongly relate to blood donor status and behaviour, mechanisms underlying these relations have not been studied sufficiently. We want to stress the importance of longitudinal studies in donor behaviour, exploring the role of life events and network characteristics within blood donor careers. Increased understanding of donor behaviour will assist policy makers of blood collection agencies, with the ultimate goal of safeguarding a sufficient and matching blood

    We report perturbed-angular-correlation (PAC) experiments on 181 Hf(→ 181 Ta)-implanted corundum Cr 2 O 3 powder samples in order to determine the magnitude and symmetry of the electric-field gradient (EFG) tensor at Ta donor impurity sites of this semiconductor. These results are analyzed in the framework of ab initio full-potential augmented-plane wave plus local orbitals (FP-APW+lo) calculations. The results are also compared with EFG results coming from PAC experiments in isomorphous α-Al 2 O 3 and α-Fe 2 O 3 doped with 111 In→ 111 Cd and 181 Hf→ 181 Ta tracers. This combined analysis enables us to quantify the magnitude of the lattice relaxations induced by the presence of the impurity and to determine the charge state of the impurity donor level introduced by Ta in the band gap of the semiconductor.

    Co-morbidity between tuberculosis and diabetes has been described since the early 20th century. In developed countries, where there has been a decrease of infectious diseases with an increase of non-communicable diseases, as well as those countries who still have a high prevalence of infectious diseases but an increase of non-communicable diseases, it is observed that the prevalence of co-morbidity between tuberculosis and diabetes is increasing, making clinical management and control at the public health level a new challenge for health systems. This review aims to show the current available evidence that can inform research lines being developed to understand the problem. In countries like Peru, where there is an epidemiological transition, further research could allow us to understand and describe in a better way the characteristics and impact of this co-morbidity.

    The macrosomia is an obstetric eventuality associated to high maternal-fetal morbidity-mortality. This assay was planned in order to know the incidence of macrosomia in our institution, the relation between vaginal and abdominal deliveries and the fetal-maternal morbidity we reviewed 3590 records and we found 5.6% incidence of macrosomia in the global obstetric population. There was 58% of vaginal deliveries, 68% of the newborn were male. The main complications were in the C. sections, 2 laceration of the hysterectomy, and 2 peroperative atonias.

    Baird, Suzanne McMurtry; Troiano, Nan H; Kennedy, Margaret Betsy Babb

    "Morbidly adherent placenta" is a term that describes the continuum of placenta accreta, increta, and percreta. The incidence of this type of abnormal placentation has increased significantly over recent decades. The reason is probably multifactorial but, partly, because of factors such as the increasing number of cesarean births. Women at greatest risk are those who have myometrial damage caused by a previous cesarean birth, with either anterior or posterior placenta previa overlying the uterine scar. This condition poses significant risks of morbidity and/or mortality to the pregnant woman and her fetus. A multidisciplinary approach to care throughout pregnancy is essential. This article describes the classification of morbidly adherent placenta, risk factors, methods of diagnosis, potential maternal and fetal complications, and intrapartum clinical management strategies to optimize outcomes.

    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.

    The need to expand the organ donor pool remains a formidable challenge in kidney transplantation (KT). The use of expanded criteria donors (ECDs) represents one approach, but kidney discard rates are high because of concerns regarding overall quality. Dual KT (DKT) may reduce organ discard and optimize the use of kidneys from marginal donors. We conducted a single-center retrospective review of outcomes in adult recipients of DKTs from adult marginal deceased donors (DD) defined by limited renal functional capacity. If the calculated creatinine clearance in an adult DD was DKT. Over 11.5 yr, 72 DKTS were performed including 45 from ECDs, 17 from donation after cardiac death (DCD) donors, and 10 from standard criteria donors (SCD). Mean adult DD and recipient ages were both 60 yr, including 29 DDs and 26 recipients ≥65 yr of age. Mean pre-DKT waiting and dialysis vintage times were 12 months and 25 months, respectively. Actual patient and graft survival rates were 84.7% and 70.8%, respectively, with a mean follow-up of 58 months. One yr and death-censored graft survival rates were 90% and 80%, respectively. Outcomes did not differ by DD category, recipient age, or presence of delayed graft function (DGF). Eleven patients died at a mean of 32 months post-DKT (eight with functioning grafts) and 13 other patients experienced graft losses at a mean of 33 months. The incidence of DGF was 25%; there were two cases (2.8%) of primary non-function. Mean length of initial hospital stay was 7.2 d. Mean serum creatinine and glomerular filtration rate levels at 12 and 24 months were 1.5 and 53 and 1.5 mg/dL and 51 mL/min/1.73 m(2) , respectively. DKT graft survival and function were superior to concurrent single ECD and similar to concurrent SCD KTs. Two patients underwent successful kidney retransplantation, so the dialysis-free rate in surviving patients was 87%. The proportion of total renal function transplanted from adult DD to DKT recipients was 77% compared to 56% for

    We describe the radiographic findings observed in a morbidly obese and diabetic patient with an intragastric air-filled balloon introduced as a therapeutic measure to reduce food intake. The balloon was associated with chronic gastric dilatation and had to be removed 3 months after insertion. However, together with diet and behavioural therapy, it proved effective in reducing body weight and ameliorating glycaemic control. Although rarely used, intragastric balloons for the treatment of morbid obesity are still encountered in radiological practice. Radiologists must be able to recognize them and to understand their complications. (orig.)

    Tourette syndrome is often associated with attention deficit hyperactivity disorder, obsessive compulsive disorder and other co-morbidities, the presence of which can reduce health-related quality of life. The relationship between the number and type of co-morbidities and tic severity upon health-related quality of life has been insufficiently examined in Tourette syndrome populations and not at all in the Australian context. We hypothesised that an increased number of co-morbid diagnoses would be inversely related to health-related quality of life and that the presence of attention deficit hyperactivity disorder and obsessive compulsive disorder in particular would negatively impact health-related quality of life. In all, 83 people with a previously established diagnosis of Tourette syndrome, who responded to a letter of invitation sent to the Tourette Syndrome Association of Australia past-member database, formed the study sample. Participants completed the Gilles de la Tourette Syndrome-Quality of Life Scale and a short form of the National Hospital Interview Schedule to assess tics and related behaviours. Participants with pure-Tourette syndrome had significantly better health-related quality of life than those with Tourette syndrome and three or more co-morbid diagnoses. Few differences were observed between the pure-Tourette syndrome and Tourette syndrome and one or two co-morbid diagnoses groups. Analysis of the impact of individual co-morbid disorders and Tourette syndrome symptoms on health-related quality of life indicated that attention deficit hyperactivity disorder exerted a significant negative effect, as did the presence of complex tics, especially coprolalia and copropraxia. When these variables were examined in multiple regression analysis, number of co-morbidities and the presence of coprophenomena emerged as significant predictors of health-related quality of life. While tics are the defining feature of Tourette syndrome, it appears to be the

    The genital mycoplasma species, Ureaplasma parvum and Ureaplasma urealyticum are the most common organisms isolated from infected amniotic fluid and placentas, and they contribute to adverse pregnancy outcomes including preterm birth and neonatal morbidities. In our institution, almost half of the preterm infants of less than 32 weeks gestation are Ureaplasma-positive in one or more compartment (respiratory, blood and/or cerebrospinal fluid), indicating that these organisms are the most common pathogens affecting this population. This review will focus on the compelling epidemiological and experimental evidence linking perinatal Ureaplasma species exposure to important morbidities of prematurity, such as bronchopulmonary dysplasia, intraventricular haemorrhage and necrotising enterocolitis.

    A retrospective cohort study of 2918 workers in the telecommunications industry in Sweden recorded the cancer morbidity for the period 1958-79. Cases of cancer were collected from the Swedish Cancer Registry for this period and information on work characteristics was collected for the entire period of employment. The total cancer morbidity was as expected. There was no excess risk of lung cancer but an excess risk of malignant melanoma of the skin was detected (SMR = 2.6, 12 cases). This excess risk was particularly associated with work environments where soldering was practised. Estimates of the SMR became larger with the assumption of a longer induction/latency period.

  6. Donor assists acceptor binding and catalysis of human α1,6-fucosyltransferase.

    α1,6-Core-fucosyltransferase (FUT8) is a vital enzyme in mammalian physiological and pathophysiological processes such as tumorigenesis and progress of, among others, non-small cell lung cancer and colon carcinoma. It was also shown that therapeutic antibodies have a dramatically higher efficacy if the α1,6-fucosyl residue is absent. However, specific and potent inhibitors for FUT8 and related enzymes are lacking. Hence, it is crucial to elucidate the structural basis of acceptor binding and the catalytic mechanism. We present here the first structural model of FUT8 in complex with its acceptor and donor molecules. An unusually large acceptor, i.e., a hexasaccharide from the core of N-glycans, is required as minimal structure. Acceptor substrate binding of FUT8 is being dissected experimentally by STD NMR and SPR and theoretically by molecular dynamics simulations. The acceptor binding site forms an unusually large and shallow binding site. Binding of the acceptor to the enzyme is much faster and stronger if the donor is present. This is due to strong hydrogen bonding between O6 of the proximal N-acetylglucosamine and an oxygen atom of the β-phosphate of GDP-fucose. Therefore, we propose an ordered Bi Bi mechanism for FUT8 where the donor molecule binds first. No specific amino acid is present that could act as base during catalysis. Our results indicate a donor-assisted mechanism, where an oxygen of the β-phosphate deprotonates the acceptor. Knowledge of the mechanism of FUT8 is now being used for rational design of targeted inhibitors to address metastasis and prognosis of carcinomas.

    Many organ procurement organizations have implemented critical care end points as donor management goals in efforts to increase organs transplanted per donor after neurologic determination of death. Although retrospective studies have demonstrated an association between meeting donor management goals and organ yield, prospective studies are lacking. In June 2008, nine donor management goals were prospectively implemented as a checklist and every donor after neurologic determination of death was managed to meet them. The donor management goals represented normal cardiovascular, pulmonary, renal, and endocrine end points. Data were collected for 7 months. Donor management goals "met" was defined a priori as achieving any seven of the nine donor management goals, and this was recorded at the time of consent, 12-18 hrs later, and prior to organ recovery. The primary outcome measure was ≥4 organs transplanted per donor, and binary logistic regression was used to identify independent predictors of this outcome with a porgan procurement organizations in the five Southwestern United States (United Network for Organ Sharing Region 5). All standard criteria donors after neurologic determination of deaths. Prospective implementation of a donor management goal checklist. There were 380 standard criteria donors with 3.6±1.7 organs transplanted per donor. Fifteen percent had donor management goals met at the time of consent, 33% at 12-18 hrs, and 38% prior to organ recovery. Forty-eight percent had ≥4 organs transplanted per donor. Donors with ≥4 organs transplanted per donor had significantly more individual donor management goals met at all three time points. Independent predictors of ≥4 organs transplanted per donor were age (odds ratio=0.95 per year), final creatinine (odds ratio=0.75 per 1-unit increase), donor management goals "met" at consent (odds ratio=2.03), donor management goals "met" prior to organ recovery (odds ratio=2.34), and a change in the number of

    Autotransplantation of premolars is a good treatment option for young patients who have missing teeth. This study evaluated the use of a preoperatively 3-dimensional (3D)-printed replica of the donor tooth that functions as a surgical guide during autotransplantation. Five consecutive procedures were prospectively observed. Transplantations of maxillary premolars with optimal root development were included in this study. A 3D-printed replica of the donor tooth was used to prepare a precisely fitting new alveolus at the recipient site before extracting the donor tooth. Procedure time, extra-alveolar time, and number of attempts needed to achieve a good fit of the donor tooth in the new alveolus were recorded. For each transplantation procedure, the surgical time was shorter than 30 minutes. An immediate good fit of the donor tooth in the new alveolus was achieved with an extra-alveolar time shorter than 1 minute for all transplantations. These results show that the extra-alveolar time is very short when the surgical guide is used; therefore, the chance of iatrogenic damage to the donor tooth is minimized. The use of a replica of the donor tooth makes the autotransplantation procedure easier for the surgeon and facilitates optimal placement of the transplant.

    Fecal microbiota transplantation is an effective treatment for recurrent Clostridium difficile infection and is being investigated as a treatment for other microbiota-associated diseases. To facilitate these activities, an international public stool bank has been created, which screens donors and processes stools in a standardized manner. The goal of this research is to use mathematical modeling and analysis to optimize screening and donor management at the stool bank. Compared to the current policy of screening active donors every 60 days before releasing their quarantined stools for sale, costs can be reduced by 10.3 % by increasing the screening frequency to every 36 days. In addition, the stool production rate varies widely across donors, and using donor-specific screening, where higher producers are screened more frequently, also reduces costs, as does introducing an interim (i.e., between consecutive regular tests) stool test for just rotavirus and C. difficile. We also derive a donor release (i.e., into the system) policy that allows the supply to approximately match an exponentially increasing deterministic demand. More frequent screening, interim screening for rotavirus and C. difficile, and donor-specific screening, where higher stool producers are screened more frequently, are all cost-reducing measures. If screening costs decrease in the future (e.g., as a result of bringing screening in house), a bottleneck for implementing some of these recommendations may be the reluctance of donors to undergo serum screening more frequently than monthly.

  15. Increasing the pool of deceased donor organs for kidney transplantation.

    Schold, Jesse D; Segev, Dorry L

    2012-03-27

    Expanding the pool of available deceased donor kidneys is critical for improving the outcomes of prospective and current renal transplant candidates. A number of interventions have been proposed that may increase the pool of donors in the US. However, these interventions have variable levels of empirical evidence supporting their potential beneficial impact. Proposed interventions include the instigation of policies for presumed donor consent, the expansion of donor registration, increased quality oversight of transplant providers, financial incentives for donors, increased reimbursement for higher risk donors, alterations in organ allocation policies and distribution, and the selective use of donors with potential or known risk for disease transmission. Many of these interventions have contentious elements that may have delayed or impeded their implementation; however, these options should be considered in the context of the diminishing prognoses for prospective transplant patients, given the increasing scarcity of donor organs relative to the population need. In this Review, we outline the proposed interventions and briefly discuss salient issues that characterize the debates concerning their implementation and effectiveness. Ultimately, any intervention must be based on the best evidence available, with consideration of numerous stakeholders and in conjunction with a careful evaluation of long-term and potential unintended consequences.

    To identify risk factors for suboptimal IVF outcomes using insemination with donor spermatozoa and to define a lower threshold that may signal a conversion to fertilization by ICSI rather than insemination. Retrospective, age-matched, case-control study of women undergoing non-donor oocyte IVF cycles using either freshly ejaculated (N=138) or cryopreserved donor spermatozoa (N=69). Associations between method of fertilization, semen sample parameters, and pregnancy rates were analyzed. In vitro fertilization of oocytes with donor spermatozoa by insemination results in equivalent fertilization and pregnancy rates compared to those of freshly ejaculated spermatozoa from men with normal semen analyses when the post-processing motility is greater than or equal to 88%. IVF by insemination with donor spermatozoa when the post-processing motility is less than 88% is associated with a 5-fold reduction in pregnancy rates when compared to those of donor spermatozoa above this motility threshold. When the post-processing donor spermatozoa motility is low, fertilization by ICSI is associated with significantly higher pregnancy rates compared to those of insemination. While ICSI does not need to be categorically instituted when using donor spermatozoa in IVF, patients should be counseled that conversion from insemination to ICSI may be recommended based on low post-processing motility.
