RESUMO
In North America, LGBTQ+ youth have high rates of cannabis use and face mental health issues. We conducted a photovoice study to describe the perspectives, needs, and motivations of forty-six LGBTQ+ youth who use cannabis as they access mental healthcare services. Participants' photographs were discussed in individual semi-structured interviews conducted by peer researchers. Following a thematic analysis of the interview transcripts, we first found that, beyond medication, LGBTQ+ youth sought mental health services facilitating introspection to better understand their sexual and gender identities and mental health. Second, participants sought affirming health professionals but often felt judged by providers. Third, access to desired services was often described as uncertain and taxing, which impacted their mental health. Fourth, participants' agency was determined by their experience with mental health services, which translated into resilience to tackle access challenges and cannabis use to mitigate their mental health struggles. Our findings point to the need for mental healthcare delivery that goes beyond medication provision but which in addition foster therapeutic processes based on a holistic understanding of mental health. A trusting dynamic between health professionals and LGBTQ+ youth is imperative to counteract the feelings of stigma experienced by LGBTQ+ youth using cannabis in Canada.
RESUMO
PURPOSE: Empathy is an important construct in patient-physician relationships, particularly critical in family physicians' daily practice. We aimed to understand how empathy has been conceived and integrated into family medicine postgraduate training. MATERIALS AND METHODS: Medline, PsyINFO, and Embase were searched in this systematic mixed studies systematic review. Two independent reviewers screened abstracts and full texts. Disagreements were solved through research team consensus-based discussion. Included studies were synthesized thematically. RESULTS: A total of 18 studies were included. Four themes were identified. (1) Empathy definition. Included studies stressed the cognitive component of empathy, paired either with a behavioural or an affective response. (2) Empathy modifiers. Starting residency right after medical school, having a role model, having high empathy levels before residency, having children, being married, and being exposed to patient involvement in education were found to have a positive impact on empathy. (3) Empathy-burnout relationship. Whereas greater burnout was related to lower empathy levels, excess empathy seems to favour burnout through 'compassion fatigue.' (4) Educational programs for empathy development. Five programs were identified: a communication workshop, a patient-led program, a mindfulness program, a family-oriented intervention, and an arts-based program. CONCLUSIONS: Studies mostly measured the cognitive component of empathy. The moral component of empathy was underrepresented in the conceptualization of empathy and the development of educational interventions. Conflicting evidence exists regarding the decline of empathy levels during the family medicine residency. Longitudinal designs should be privileged when exploring the evolution of empathy levels across the continuum of medical education.
RESUMO
AIMS: This study aimed to examine antibiotic resistance and the epidemiology of extended-spectrum ß-lactamases (ESBL)-producing Escherichia coli associated with bloodstream infections over a period of 10 years. METHODS AND RESULTS: Isolates were collected from January 2009 to December 2019 and those testing for E. coli were included. Antibiotic susceptibility was tested using the VITEK® system. Selected isolates were further characterized by amplification of marker genes (virulence traits, phylogroups, and sequence types). A total of 166 ESBL-producing E. coli were recovered. The blaCTX-M-15 allele was the most abundant. Most of the isolates were resistant to ceftriaxone, cefepime, ceftazidime, ampicillin/sulbactam, piperacillin/tazobactam, and ciprofloxacin. No resistance to carbapenems was registered. More than 80% of bacteria were classified as extraintestinal pathogenic E. coli (ExPEC), and the combination of virulence traits:papA-papC-kpsMII-uitA was the most common. Phylogroup B2 was the most prevalent, and bacteria predominantly belonged to ST131. CONCLUSIONS: There was an increase in the ExPEC ESBL-E coli in bloodstream infections and the relationship between the isolates found in these infections during these 10 years.

INTRODUCTION: The transperitoneal laparoscopic approach is considered the gold standard technique for living kidney donation. Other accepted laparoscopic techniques include the retroperitoneal approach, natural orifice transluminal endoscopic surgery (NOTES)-assisted, laparo-endoscopic single-site surgery (LESS), with excellent results in the donor and graft. Many studies have compared these techniques with open ones. Our objective is to describe our experience and results in minimally invasive living-donor nephrectomies (MILDN): laparoscopic, NOTES-assisted, and LESS since their introduction in March 2002. MATERIALS AND METHODS: We conducted a retrospective observational study of donors undergoing MILDN between March 2002 and March 2020. RESULTS: A total of 714 MILDNs were performed at our centre. All were completed, except for one, because of recipient death. The conventional laparoscopic approach was used in 541 cases (75.88%), NOTES in 116 (16.9%), LESS in 55 (7.7%), and one mini open (0.14%). Two-thirds of the donors were females (478 cases). The mean donor age was 52.87 years (SD 10.93). Six donors (0.8%) were diagnosed beforehand with a small renal mass, which was removed before transplantation in bench surgery. The right kidney was removed in 17.8% of cases. Warm ischaemia time was higher in the NOTES and LESS groups. We had eight conversions. The global intraoperative and postoperative complication rates were 6.8% and 4.9%, respectively. None of the donors developed renal disease during follow-up (mean 3.68 years). Five-year recipient and graft survival rates were 98.8% and 96.8%, respectively. CONCLUSIONS: MILDN techniques are safe for donors and grafts, with low complication.

Simultaneous pancreas-kidney transplantation (SPKT) leads to increased survival and quality of life, and is an alternative treatment for insulin-dependent diabetes mellitus and end-stage kidney disease. Due to the particularities of this population (often with multiple comorbidities) and of the surgery (only performed in a few centers), a comprehensive analysis of patients' experience along the SPKT process is crucial to improve patient care and add value to this procedure. Therefore, we applied a systematic and iterative methodology with the participation of both patients and professional teams working together to explore and identify unmet needs and value-adding steps along the transplant patient journey at an established pancreas transplant program. Four main steps (to comprehend, to explore, to experiment and to assess) led to several interventions around three major areas: Administration and logistics, information and communication, and perceived quality of assistance. As a result, both displacements to the hospital for diagnostic purposes and the time delay involved in joining the patient waiting list for transplantation were reduced in parallel to the administrative procedures. In conclusion, the methodological implementation of key organizational changes has great impact on overall patient experience. Further quantitative analysis from the patient's perspective will consolidate our program and may add new prototype service design components.

Due to the high vulnerability of the pancreas to ischemia-reperfusion injury, choices regarding preservation solution markedly affect pancreas transplant success. A retrospective single-center analysis of 380 pancreas transplants (2000-2019) was performed to correlate current preservation solutions with transplant outcomes. Early graft failure requiring transplantectomy within 30 days post-transplant occurred in 7.5% for University of Wisconsin (UW) group (n = 267), 10.8% of Celsior (CS) group (n = 83), 28.5% of Histidine-Tryptophan-Ketoglutarate (HTK) group (n = 7), and none for Institut Georges Lopez-1 (IGL-1) group (n = 23). The most common causes of technical failures in this cohort included abdominal hemorrhage (8.4%); graft pancreatitis (3.7%); fluid collections (2.6%); intestinal complications (6.6%); and vascular thrombosis (20.5%). Although IGL-1 solution provided lower surgical complication rates, no significant differences were found between studied groups. Nevertheless, HTK solution was associated with elevated pancreatitis rates. The best graft survival was achieved at 1 year using UW and IGL-1, and at 3 and 5 years using IGL-1 (p = 0.017). There were no significant differences in patient survival after a median follow-up of 118.4 months. In this setting therefore, IGL-1 solution appears promising for perfusion and organ preservation in clinical pancreas transplantation, compared to other commonly used solutions.

INTRODUCTION: HLA sensitization is a growing problem in children awaiting kidney transplantation. In some cases, finding an immunologically compatible donor entails contemplating the option of an ABO incompatible transplant or paired transplant. METHODS: Patient with genetic nephrotic syndrome and progressive chronic kidney disease, with a previous thrombosis of a first kidney transplant, resulting hypersensitized and remaining for a long-time on hemodialysis. Despite a desensitization strategy, family members were incompatible and deceased donation options must be ruled out due to the presentation of donor-specific antibodies (DSA). After 4 years, the possibility arises to perform a kidney paired transplant with a 62-year-old woman with an incompatible blood group. Although the current cytotoxicity- and cell-based crossmatches were negative, history of DSA were recorded. RESULTS: An intensive ABO and HLA desensitization protocol was performed in order to combat the isohemagglutinin antibodies and on the memory-HLA, based on rituximab, apheresis sessions, and immunoglobulins. Despite the donor being older in terms of pediatric transplantation, the donor-recipient weight difference, and immunological risk, the transplant was completed successfully. Maintenance of titration of up to 1/2 was confirmed after 3 weeks post-transplant (IgM and IgG). Kidney biopsy at 2 weeks and 6 months without signs of rejection. The patient is currently 12 months post-transplant and has not presented any signs of transplant rejection and has proper renal function. CONCLUSIONS: Kidney paired transplantation is an excellent solution for hypersensitized children, and ABO incompatibility can be considered to increase their options to find a good donor, without thereby obtaining worse results.

PHENOMENON: Clinical teachers perform overlapping tasks in education and patient care. They are therefore expected to juggle many professional identities such as educator and clinician. Yet little is known about how clinical teachers negotiate their professional identities. The present research examined the lived experiences of clinical teachers as they manage and make sense of their professional identities in the context of a faculty development program. APPROACH: This study adopted interpretative phenomenological analysis, which is an idiographic and inductive methodological approach that enables an in-depth examination of how people conceptualize their personal and social worlds. In-depth semi-structured individual interviews were conducted with six purposively sampled Brazilian clinical teachers who were attending a faculty development program. Each participant's lived experience was analyzed independently. Then, these individual analyses were compared against each other to identify convergence and divergence. FINDINGS: Participants recognized one identity, which was labeled as embedding identity, containing other identities and roles. Participants integrated their professional identities in agreement with their personal identities, values, and beliefs, striving thus for identity consonance. Participants understood their craft as a relational process by which they wove themselves into their context and entangled their experience with that of others. They, however, diverged when recognizing who their peers were; whereas some named a single professional group (i.e., family physicians), others had a more comprehensive view and considered as peers healthcare professionals, students, and even patients. Finally, participants identified time constraints and lower prestige of family medicine as a medical discipline vis-à-vis other specialties as challenges posed by their contexts. INSIGHTS: Clinical teachers have multifaceted identities, to which they give a sense, manage, and integrate into their daily practice. Participants recognized an embedding identity and looked for common points between the identities it contained, which allowed them to meaningfully reconcile the different demands from their overlapping professional identities. Thus, this research introduces the notion of embedding identity as a strategy to make sense of many professional identities. Variability in the embedding identities depicted in this investigation suggests the fluid and contextualized character of professional identity development. How participants saw themselves also influenced how they behaved and interacted with others accordingly. Understanding clinical teacher identity development enriches current perspectives of what it is like to be one of these medical professionals. Faculty development programs ought to consider these perspectives to better support clinical teachers in meeting the overlapping demands in education and patient care.

OBJECTIVE: The aim of the study was to evaluate the effect of cardiac arrest time (CAT) in donors after brain death (DBD) donors on pancreas transplant outcome. SUMMARY OF BACKGROUND DATA: Results from donors after circulatory death report good outcomes despite warm ischemia times up to 57 minutes. Previous cardiac arrest in DBD has been addressed as a potential risk factor, but duration of the CAT has never been evaluated. METHODS: We conducted a retrospective analysis including 342 pancreas transplants performed at our center from 2000 to 2016, and evaluated the effect of previous cardiac arrest in DBD (caDBD) on pancreas transplant outcomes. RESULTS: A total of 49 (14.3%) caDBD were accepted for transplantation [median CAT of 5.0 min (IQR 2.5-15.0)]. Anoxic encephalopathy was most frequent and P-PASS higher (16.9 vs 15.6) in caDBD group when compared with other DBD. No differences were found in all other characteristics evaluated.Graft survival was similar between both groups, as was the incidence of early graft failure (EGF). CAT increased the risk for EGF [OR 1.09 (95% CI, 1.01-1.17)], and the duration of CPR discriminated for EGF [AUC of 0.86 (95% CI, 0.74-0.98)], with a sensitivity and specificity of 100% and 75% at a cutoff of 15âminutes. When evaluated separately, caDBD >15âmin increased over 5 times the risk for EGF [HR 5.80 (95% CI, 1.82-18.56); P = 0.003], and these presented fewer days on the ICU (1.0 vs 3.0 d). CONCLUSION: CaDBD donors are suitable for routine pancreas transplantation without increasing EGF risk, and in those with longer CAT it may be prudent to postpone donation a few days to allow a thorough evaluation of organ damage following cardiac arrest.

INTRODUCTION: The current pool of organs available for transplantation does not cover requirements, for this reason non-standard risk donors need to be incorporated into the pool. In this way, donors with small renal tumour are considered for transplantation after bench tumour excision. The aim of our study was to analyse our experience in using these grafts for transplantation. MATERIALS AND METHODS: Retrospective analysis from our prospective accrued database of donors with incidental renal mass used for kidney transplantation between January 2007 and August 2018. RESULTS: Twenty kidney transplantations were performed, thirteen cases received the affected kidney (after tumour removal) and seven the contralateral kidney; from six living and eleven deceased donors. Donor and recipient median age was 58 years (range 22-82) and 56.5 years (range 38-74), respectively. Mean tumour diameter was 12.7 mm (SD 9.5). Tumours resulted in two benign lesions and fifteen renal cell carcinoma. Surgical margins were negative. Two cases presented with bleeding after reperfusion was solved without repercussion. One case presented with immediate vein thrombosis. None of them present delayed graft function. After a 69 month follow-up none of the donors or the recipients presented tumour recurrence. CONCLUSIONS: Kidneys with small incidental tumours seem to be a good option for kidney transplantation in selected patients after bench surgery excision with good functional and oncologic results. More studies and longer follow-up are needed to confirm these results.

This article describes a pathway for collaboration between transplant healthcare professionals and organ recipients. Under the umbrella of the European Society for Organ Transplantation (ESOT) a joint initiative started from three Sections and Committees of ESOT: EDTCO (European Donation and Transplant Coordination Organisation), ETHAP (European Transplant Allied Healthcare Professionals) and ELPAT (Ethical, Legal and Psycho-social Aspects of Transplantation). The formal 'kick-off' of the Advisory Board Meeting of the European Transplant Patient Organisation (ETPO) was during the ESOT congress in 2019. The aim was to produce a series of statements to serve as a path to dialogue between patients and transplant professionals and to define the next steps towards giving a voice to the patient network. To include the patients' perspectives, two surveys have been performed. The results identified the unmet needs and lead to a proposal for future plans. Educational activities have since started leading to a patient learning workstream. All initiatives taken have one purpose: to include patients, give them a voice and build a foundation for collaboration between patients and transplant professionals. ESOT has created a platform for mutual understanding, learning and a collaborative partnership between ETPO and European donation and transplant professionals.

Normothermic regional perfusion (NRP) in donation after circulatory death (DCD) is a safe alternative to in situ cooling and rapid procurement. An increasing number of countries and centres are performing NRP, a technically and logistically challenging procedure. This consensus document provides evidence-based recommendations on the use of NRP in uncontrolled and controlled DCDs. It also offers minimal ethical, logistical and technical requirements that form the foundation of a safe and effective NRP programme. The present article is based on evidence and opinions formulated by a panel of European experts of Workstream 04 of the Transplantation Learning Journey project, which is part of the European Society for Organ Transplantation.

In donation after circulatory death (DCD), (thoraco)abdominal regional perfusion (RP) restores circulation to a region of the body following death declaration. We systematically reviewed outcomes of solid organ transplantation after RP by searching PubMed, Embase, and Cochrane libraries. Eighty-eight articles reporting on outcomes of liver, kidney, pancreas, heart, and lung transplants or donor/organ utilization were identified. Meta-analyses were conducted when possible. Methodological quality was assessed using National Institutes of Health (NIH)-scoring tools. Case reports (13/88), case series (44/88), retrospective cohort studies (35/88), retrospective matched cohort studies (5/88), and case-control studies (2/88) were identified, with overall fair quality. As blood viscosity and rheology change below 20 °C, studies were grouped as hypothermic (HRP, ≤20 °C) or normothermic (NRP, >20 °C) regional perfusion. Data demonstrate that RP is a safe alternative to in situ cold preservation (ISP) in uncontrolled and controlled DCDs. The scarce HRP data are from before 2005. NRP appears to reduce post-transplant complications, especially biliary complications in controlled DCD livers, compared with ISP. Comparisons for kidney and pancreas with ISP are needed but there is no evidence that NRP is detrimental. Additional data on NRP in thoracic organs are needed. Whether RP increases donor or organ utilization needs further research.

Urban river pollution by multidrug-resistant (MDR) bacteria constitutes an important public health concern. Epidemiologically important strains of MDR Escherichia coli transmissible at the human-animal-environment interfaces are especially worrying. Quantifying and characterizing MDR E. coli at a molecular level is thus imperative for understanding its epidemiology in natural environments and its role in the spread of resistance in precise geographical areas. Cefotaxime-resistant E. coli was characterized along the watercourse of the major urban river in Quito. Our results showed high quantities of cefotaxime-resistant E. coli (2.7 × 103-5.4 × 105 CFU/100 mL). The antimicrobial resistance index (ARI) revealed the exposure of the river to antibiotic contamination, and the multiple antibiotic resistance index indicated a high risk of contamination. The blaCTX-M-15 gene was the most prevalent in our samples. Isolates also had class 1 integrons carrying aminoglycoside-modifying enzymes and folate pathway inhibitors. The isolates belonged to phylogroups A, B1 and D. Clonal complex 10 was found to be the most prevalent (ST10, ST44 and ST 167), followed by ST162, ST394 and ST46. Our study provides a warning about the high potential of the major urban river in Quito for spreading the epidemiologically important MDR E. coli.

BACKGROUND: The criteria for kidney suitability in uncontrolled donors after circulatory death (uDCD) procured after regional normothermic perfusion are based on macroscopic appearance and renal haemodynamic values with final renal resistance (FRR). However, these criteria have not been analysed to predict the future graft function. This study presents a model to predict the outcome in uDCD kidneys and define the predictive FRR value. METHODS: All uDCD kidney transplants performed in our hospital from 2004 to 2016 were included. Donors and recipients and pre-transplantation data are described. The endpoint was glomerular filtration rate (GFR) ≥30 mL/min at 6 months after transplantation. RESULTS: A total of 194 recipients were included. FRR in donors ≥60 years old was (mean ± SD) 0.27 ± 0.11 versus 0.22 ± 0.09 mmHg/mL/min in donors <60 years (P = 0.042). Kidney survival was 88.2% versus 84% at 12 months and 60.7% versus 30.8% at 120 months (P = 0.067). For the group of recipients from donors ≥60 years, the FRR was 0.37 ± 0.08 mmHg/mL/min in the GFR <30 mL/min group versus 0.18 ± 0.06 mmHg/mL/min in the GFR ≥30 mL/min group (P < 0.001). The value FRR ≥0.3 mmHg/mL/min predicts 59-79% of GFR <30 mL/min [odds ratio = 2.16, 95% confidence interval (CI) 1.80-6.40; P < 0.001]. The predictive accuracy of FRR for GFR by ROC curve was 0.968 (95% CI). The best cut-off for FRR was 0.3 mmHg/mL/min to predict GFR at 6 months with a sensitivity of 67%, specificity of 100%, positive predictive value of 83% and negative predictive value of 92%. CONCLUSIONS: Our results suggest that in uDCD donors the combination of donor age ≥60 years together with FRR ≥0.3 mmHg/mL/min could predict poor outcome at 6 months after transplantation in low immunological risk recipients.

Background: Pancreas outcomes in pancreas after kidney transplantation (PAK) patients have been reported as being inferior to those of patients who receive simultaneous pancreas and kidney transplantation (SPK). The influence of the kidney donor (i.e. living versus deceased) has never been previously addressed. Methods: We retrospectively analysed all pancreas transplants performed in a single centre since 2007 and compared the outcomes between those patients who had previously received a living-donor kidney transplant (pancreas transplantation after living-donor kidney transplantation, PAldK; n = 18) or a deceased-donor kidney transplant (pancreas transplantation after deceased-donor kidney transplantation, PAddK; n = 28), using SPK (n = 139) recipients as a reference. Results: Pancreas survival was similar between all groups, but inferior for PAldK when including only those with a functioning graft at day 90 post-transplantation (P = 0.004). Pancreas acute rejection was significantly increased in PAldK (67%; 1.8 ± 1.4 episodes/graft) when compared with PAddK (25%) and SPK (32%) (P < 0.05) patients. In a multivariate Cox regression model including known risk factors for pancreas rejection, PAldK was the only predictor of acute rejection (hazard ratio 6.82, 95% confidence interval 1.51-30.70, P < 0.05). No association was found between donor-recipient HLA mismatches and graft rejection. Repeated HLA mismatches between kidney and pancreas donors (0 versus 1-6) did not correlate with pancreas graft rejection or survival in either PAK transplantation group (P > 0.05). Conclusion: Pancreas graft outcomes are worse for PAldK when compared with PAddK and SPK patients.

Living kidney donors seem highly satisfied with donation. However, previous studies measure satisfaction by a single-item or by simply questioning donors' willingness to donate again or to recommend living donation. With the aim of analyzing whether satisfaction with donation is a multidimensional construct, thus allowing a more specific characterization of dissatisfied donors, 332 living kidney donors (2005-2015) answered a renewed version of the European Living Donation and Public Health Project satisfaction survey. Exploratory factor-analyses suggested that satisfaction was composed of three-factors: violation of donors' expectancies about donation; interference of donation on daily activities, and pain and discomfort. Donors reported high levels of satisfaction. However, cluster-analysis identified a subgroup characterized by a higher discrepancy between the expected and the actually experienced during donation, higher interference on daily activities, and higher pain and discomfort. Most of them considered that hospital discharge was premature, suffered economic losses and perceived worse health outcomes of their recipients. Single questions assessing donors' willingness to donate again or to recommend living donation were unable to differentiate between clusters. In summary, donor's satisfaction seems better characterized by three dimensions than by single questions.

There is no consensus on the allocation of renal transplants from expanded criteria donors (ECD). The Kidney Donor Profile Index (KDPI) is used without the need for pretransplant donor biopsies (PTDB). We explored whether PTDB based on Remuzzi Score (RS) allows identification of those marginal kidneys in the highest calculated KDPI risk group (>91%) that appropriate for single transplantation. A retrospective study was conducted of 485 consecutive kidneys procured from a single center and transplanted if the RS was ≤4. We compared 5-year kidney and patients survival between KDPI groups and between RS <4 or =4 in the highest KDPI group. The median KDPI (interquartile range) was 71 (66-76) for KDPI <80% (n = 77), 86 (81-90) for KDPI 81-90% (n = 82), and 97 (94-100) for KDPI >91% (n = 205). Patient survival at 5 years was 85.7%, 85.3%, and 76.09% (P = 0.058) and death-censored graft survival was 84.4%, 86.5%, 73.6% (P = 0.015), respectively for each KDPI group. In >91% calculated KDPI group, there were no differences in graft survival depending on the RS (<4 vs. =4) (P = 0.714). The implementation of PTDB based on RS used for allocation of organs with the highest KDPI range could support to the acceptance of suitable organs for single transplantation with good patient and graft survival rate.

INTRODUCTION: The clinical results of ABO-incompatible (ABOi) and ABO-compatible (ABOc) kidney transplantation (KT) are similar. Protocol kidney biopsies (PKB) of ABOi transplant recipients show positivity for C4d without evidence of antibody-mediated rejection (ABMR), but little is known about the histologic progression. METHOD: We evaluated histologic parameters in PKB at 12 months and also compared clinical outcome at 1 year. This is a prospective observational study conducted between 2009 and 2013. We performed 146/30 ABOc/ABOi consecutive living-donor KT with PKB as well as additional indication biopsies. In the ABOi group, the desensitization protocol consisted of rituximab, plasma exchange or immunoadsorption, and immunoglobulins. RESULTS: In indication biopsies during the first year, T-cell-mediated rejection Banff ≥immunoadsorption was 8.2% vs 6.7% (P=.561) and ABMR 4.8% vs 13.3% (P=.095). At 1 year, PKB (ABOc/ABOi) showed differences in borderline rejection lesions (6.8% vs 23.3% [P=.012]) and in C4d positivity in the ABOi group (P=.001). Interstitial fibrosis and tubular atrophy (IFTA) lesions (ABOc/ABOi) were 68.4% vs 63.2% (P=.348). Transplant glomerulopathy was 0.7% vs 3.3% (P=.373) at 1 year. CONCLUSIONS: Our PKB ABOi series shows at 1 year more borderline lesions independent of ABO titers, HLA incompatibility, and the presence of antidonor antibody, but do not show more IFTA nor transplant glomerulopathy. No clinical differences were observed between ABOi and ABO transplants.

Pre-implantation renal biopsies of expanded criteria donors are one of the criteria used for allocation decisions, but there are concerns about the impact of the interobserver variability and the technique to be used. The aim was (i) to compare the original report performed by on-call pathologists using frozen sections (FS) to a retrospective analysis carried out by a trained pathologist using the same frozen section, and (ii) to compare the same FS to subsequently obtained paraffin sections (PS) by the same pathologist. A total of 92 biopsies, 78 from transplanted and 14 from nontransplanted cases, were analyzed. Agreement between observers using the same FS was weaker than the correlation between FS and PS in all the examined parameters (Kendall's Tau b for the Remuzzi score 0.104 vs. 0.306). According to the Remuzzi score, the revised FS analysis would have resulted in a higher rate of organ discard (n = 19) than PS (n = 14) and the original report (n = 6). However, kidneys that would have been discarded according to the retrospective analysis showed adequate outcomes in terms of graft survival and function. Accordingly, the impact of interobserver and technique-related variability can be minimized by the use of a relatively low threshold (RS ≤ 4) for organ acceptance.
