Recent outcomes of liver transplantation for Budd-Chiari syndrome: A study of the European Liver Transplant Registry (ELTR) and affiliated centers.

BACKGROUND AND AIMS: Management of Budd-Chiari syndrome (BCS) has improved over the last decades. The main aim was to evaluate the contemporary post-liver transplant (post-LT) outcomes in Europe. APPROACH AND RESULTS: Data from all patients who underwent transplantation from 1976 to 2020 was obtained from the European Liver Transplant Registry (ELTR). Patients < 16 years, with secondary BCS or HCC were excluded. Patient survival (PS) and graft survival (GS) before and after 2000 were compared. Multivariate Cox regression analysis identified predictors of PS and GS after 2000. Supplemental data was requested from all ELTR-affiliated centers and received from 44. In all, 808 patients underwent transplantation between 2000 and 2020. One-, 5- and 10-year PS was 84%, 77%, and 68%, and GS was 79%, 70%, and 62%, respectively. Both significantly improved compared to outcomes before 2000 ( p < 0.001). Median follow-up was 50 months and retransplantation rate was 12%. Recipient age (aHR:1.04,95%CI:1.02-1.06) and MELD score (aHR:1.04,95%CI:1.01-1.06), especially above 30, were associated with worse PS, while male sex had better outcomes (aHR:0.63,95%CI:0.41-0.96). Donor age was associated with worse PS (aHR:1.01,95%CI:1.00-1.03) and GS (aHR:1.02,95%CI:1.01-1.03). In 353 patients (44%) with supplemental data, 33% had myeloproliferative neoplasm, 20% underwent TIPS pre-LT, and 85% used anticoagulation post-LT. Post-LT anticoagulation was associated with improved PS (aHR:0.29,95%CI:0.16-0.54) and GS (aHR:0.48,95%CI:0.29-0.81). Hepatic artery thrombosis and portal vein thrombosis (PVT) occurred in 9% and 7%, while recurrent BCS was rare (3%). CONCLUSIONS: LT for BCS results in excellent patient- and graft-survival. Older recipient or donor age and higher MELD are associated with poorer outcomes, while long-term anticoagulation improves both patient and graft outcomes.

The role of HBIG in real life for patients undergoing liver transplantation due to HDV-related cirrhosis.

Recommended post-liver transplant (LT) prophylaxis in patients with hepatitis delta includes a nucleos(t)ide analogue (NA) and anti-hepatitis B immunoglobulin (HBIG) indefinitely. We analysed the use of HBIG in real-life clinical practice and its impact on HBV/HDV recurrence in 174 HDV-related LT patients from 10 Spanish liver transplant centres (1988-2018). Median post-LT follow-up was 7.8 (2.3-15.1) years and patient survival at 5 years was 90%. Most patients (97%) received HBIG in the immediate post-LT, but only 42% were on HBIG at the last control. Among those discontinuing HBIG, the median time on treatment was 18 (7-52) months. Post-LT HBsAg+ was detected in 16 (9%) patients and HBV-DNA in 12 (7%). Despite HBsAg positivity, HDV recurrence was reported only in three patients (1.7%), all of whom were not receiving NA and had discontinued HBIG. Our data suggest that a finite HBIG prophylaxis in HDV-LT is feasible, especially if high-barrier NAs are used.

Women Are Also Disadvantaged in Accessing Transplant Outside the United States: Analysis of the Spanish Liver Transplantation Registry.

Sex inequities in liver transplantation (LT) have been documented in several, mostly US-based, studies. Our aim was to describe sex-related differences in access to LT in a system with short waiting times. All adult patients registered in the RETH-Spanish Liver Transplant Registry (2000-2022) for LT were included. Baseline demographics, presence of hepatocellular carcinoma, cause and severity of liver disease, time on the waiting list (WL), access to transplantation, and reasons for removal from the WL were assessed. 14,385 patients were analysed (77% men, 56.2 ± 8.7 years). Model for end-stage liver disease (MELD) score was reported for 5,475 patients (mean value: 16.6 ± 5.7). Women were less likely to receive a transplant than men (OR 0.78, 95% CI 0.63, 0.97) with a trend to a higher risk of exclusion for deterioration (HR 1.17, 95% CI 0.99, 1.38), despite similar disease severity. Women waited longer on the WL (198.6 ± 338.9 vs. 173.3 ± 285.5 days, p < 0.001). Recently, women's risk of dropout has reduced, concomitantly with shorter WL times. Even in countries with short waiting times, women are disadvantaged in LT. Policies directed at optimizing the whole LT network should be encouraged to guarantee a fair and equal access of all patients to this life saving resource.

Alternative forms of portal vein revascularization in liver transplant recipients with complex portal vein thrombosis.

BACKGROUND & AIMS: Complex portal vein thrombosis (PVT) is a challenge in liver transplantation (LT). Extra-anatomical approaches to portal revascularization, including renoportal (RPA), left gastric vein (LGA), pericholedochal vein (PCA), and cavoportal (CPA) anastomoses, have been described in case reports and series. The RP4LT Collaborative was created to record cases of alternative portal revascularization performed for complex PVT. METHODS: An international, observational web registry was launched in 2020. Cases of complex PVT undergoing first LT performed with RPA, LGA, PCA, or CPA were recorded and updated through 12/2021. RESULTS: A total of 140 cases were available for analysis: 74 RPA, 18 LGA, 20 PCA, and 28 CPA. Transplants were primarily performed with whole livers (98%) in recipients with median (IQR) age 58 (49-63) years, model for end-stage liver disease score 17 (14-24), and cold ischemia 431 (360-505) minutes. Post-operatively, 49% of recipients developed acute kidney injury, 16% diuretic-responsive ascites, 9% refractory ascites (29% with CPA, p <0.001), and 10% variceal hemorrhage (25% with CPA, p = 0.002). After a median follow-up of 22 (4-67) months, patient and graft 1-/3-/5-year survival rates were 71/67/61% and 69/63/57%, respectively. On multivariate Cox proportional hazards analysis, the only factor significantly and independently associated with all-cause graft loss was non-physiological portal vein reconstruction in which all graft portal inflow arose from recipient systemic circulation (hazard ratio 6.639, 95% CI 2.159-20.422, p = 0.001). CONCLUSIONS: Alternative forms of portal vein anastomosis achieving physiological portal inflow (i.e., at least some recipient splanchnic blood flow reaching transplant graft) offer acceptable post-transplant results in LT candidates with complex PVT. On the contrary, non-physiological portal vein anastomoses fail to resolve portal hypertension and should not be performed. IMPACT AND IMPLICATIONS: Complex portal vein thrombosis (PVT) is a challenge in liver transplantation. Results of this international, multicenter analysis may be used to guide clinical decisions in transplant candidates with complex PVT. Extra-anatomical portal vein anastomoses that allow for at least some recipient splanchnic blood flow to the transplant allograft offer acceptable results. On the other hand, anastomoses that deliver only systemic blood flow to the allograft fail to resolve portal hypertension and should not be performed.

Effectiveness and safety of once-daily tacrolimus formulations in de novo liver transplant recipients: The PRETHI study.

Data comparing long-term effectiveness and safety of once-daily tacrolimus formulations in de novo liver transplantation are scarce. We compared the effectiveness, pharmacokinetic profile, and safety of LCPT (Envarsus) and PR-Tac (Advagraf) for up to 12 months post-transplant. Adult de novo liver transplant recipients who started IR-Tac (Prograf) and were converted to LCPT or PR-Tac 3-5 days post-transplant were included. Data from 163 patients were analyzed, 87 treated with LCPT and 76 with PR-Tac. The incidence of treatment failure was 30.5% in the LCPT group versus 23.0% in the PR-Tac group (p = .291). Biopsy-proven acute rejection (BPAR) was reported in 26.8% of patients in the LCPT group and 17.6% in the PR-Tac group (p = .166). Graft loss was experienced in one patient (1.2%) in the LCPT group and three patients (4.1%) in the PR-Tac group (p = .346). Death was registered in three patients (3.7%) in the LCPT group and three patients (4.1%) in the PR-Tac group (p > .999). Patients in the LCPT group showed 45.7% higher relative bioavailability (Cmin /total daily dose [TDD]; p < .01) with similar Cmin and 33.3% lower TDD versus PR-Tac (p < .01). The evolution of renal function, safety profile, and the incidence of post-transplant renal failure, dyslipidemia, obesity, hypertension, and diabetes mellitus were similar in patients treated with LCPT and PR-Tac. In de novo liver transplant patients, LCPT and PR-Tac showed comparable effectiveness with higher relative bioavailability, similar Cmin and lower TDD in the LCPT group. Renal function, safety, and post-transplant complications were comparable in LCPT and PR-Tac groups.

[Alarming signals: Worsening obesity, physical inactivity and high perception of stress in first-year medical and dental students in Chile]. / Señales de Alarma: Empeoramiento de la Obesidad, Inactividad Física y Alta Percepción de Estrés en Estudiantes de Primer Año de la Facultad de Medicina y Odontología de la Universidad de Chile.

BACKGROUND: The high prevalence of obesity, smoking, and physical inactivity in Chile despite government-sponsored measures and campaigns, along with others in the last 30 years, suggests additional reinforcement of these efforts at the primary care level. OBJECTIVES: To determine if lifestyles and modifiable health risk factors in first-year students from the University of Chile Faculties of Medicine and Dentistry, potential future promoters of healthy lifestyles, show changes throughout their first academic year. METHODS: In a randomized stratified sample of 388 students according to sex and chosen career weight, height, waist circumference, waist circumference-weight ratio, food consumption, smoking prevalence and dependence, alcohol use, perceived stress level, and physical activity were measured at the first week, 3 and 6 months after their admission. The Cochrane test assessed dichotomic variables, and the Friedman test was used for nonparametric values. RESULTS: 253 students (186 women) completed the follow-up. A significant worsening of obesity (general and abdominal) and physical inactivity, persistent moderate and high-stress perception, and smoking prevalence were documented throughout the study period. CONCLUSIONS: The progressive obesity and physical inactivity, high-stress perception, and persistent smoking prevalence in the first year of academic life suggest considering measures in the curricular academic structure that facilitate adjustments in the student's lifestyles. Future follow-up of this cohort, increasing participants, and assessing students' mental health are planned.

Abdominal normothermic regional perfusion in controlled donation after circulatory determination of death liver transplantation: Outcomes and risk factors for graft loss.

Postmortem normothermic regional perfusion (NRP) is a rising preservation strategy in controlled donation after circulatory determination of death (cDCD). Herein, we present results for cDCD liver transplants performed in Spain 2012-2019, with outcomes evaluated through December 31, 2020. Results were analyzed retrospectively and according to recovery technique (abdominal NRP [A-NRP] or standard rapid recovery [SRR]). During the study period, 545 cDCD liver transplants were performed with A-NRP and 258 with SRR. Median donor age was 59 years (interquartile range 49-67 years). Adjusted risk estimates were improved with A-NRP for overall biliary complications (OR 0.300, 95% CI 0.197-0.459, p < .001), ischemic type biliary lesions (OR 0.112, 95% CI 0.042-0.299, p < .001), graft loss (HR 0.371, 95% CI 0.267-0.516, p < .001), and patient death (HR 0.540, 95% CI 0.373-0.781, p = .001). Cold ischemia time (HR 1.004, 95% CI 1.001-1.007, p = .021) and re-transplantation indication (HR 9.552, 95% CI 3.519-25.930, p < .001) were significant independent predictors for graft loss among cDCD livers with A-NRP. While use of A-NRP helps overcome traditional limitations in cDCD liver transplantation, opportunity for improvement remains for cases with prolonged cold ischemia and/or technically complex recipients, indicating a potential role for complimentary ex situ perfusion preservation techniques.

A scoring system for predicting malignancy in intraductal papillary mucinous neoplasms of the pancreas: a multicenter EUROPEAN validation.

PURPOSE: A preoperative estimate of the risk of malignancy for intraductal papillary mucinous neoplasms (IPMN) is important. The present study carries out an external validation of the Shin score in a European multicenter cohort. METHODS: An observational multicenter European study from 2010 to 2015. All consecutive patients undergoing surgery for IPMN at 35 hospitals with histological-confirmed IPMN were included. RESULTS: A total of 567 patients were included. The score was significantly associated with the presence of malignancy (p < 0.001). In all, 64% of the patients with benign IPMN had a Shin score < 3 and 57% of those with a diagnosis of malignancy had a score ≥ 3. The relative risk (RR) with a Shin score of 3 was 1.37 (95% CI: 1.07-1.77), with a sensitivity of 57.1% and specificity of 64.4%. CONCLUSION: Patients with a Shin score ≤ 1 should undergo surveillance, while patients with a score ≥ 4 should undergo surgery. Treatment of patients with Shin scores of 2 or 3 should be individualized because these scores cannot accurately predict malignancy of IPMNs. This score should not be the only criterion and should be applied in accordance with agreed clinical guidelines.

Effects of everolimus plus minimized tacrolimus on kidney function in liver transplantation: REDUCE, a prospective, randomized controlled study.

BACKGROUND AND AIM: reduction in calcineurin inhibitor levels is considered crucial to decrease the incidence of kidney dysfunction in liver transplant (LT) recipients. The aim of this study was to evaluate the safety and impact of everolimus plus reduced tacrolimus (EVR + rTAC) vs. mycophenolate mofetil plus tacrolimus (MMF + TAC) on kidney function in LT recipients from Spain. METHODS: the REDUCE study was a 52-week, multicenter, randomized, controlled, open-label, phase 3b study in de novo LT recipients. Eligible patients were randomized (1:1) 28 days post-transplantation to receive EVR + rTAC (TAC levels ≤ 5 ng/mL) or to continue with MMF + TAC (TAC levels = 6-10 ng/mL). Mean estimated glomerular filtration rate (eGFR), clinical benefit in renal function, and safety were evaluated. RESULTS: in the EVR + rTAC group (n = 105), eGFR increased from randomization to week 52 (82.2 [28.5] mL/min/1.73 m2 to 86.1 [27.9] mL/min/1.73 m2) whereas it decreased in the MMF + TAC (n = 106) group (88.4 [34.3] mL/min/1.73 m2 to 83.2 [25.2] mL/min/1.73 m2), with significant (p < 0.05) differences in eGFR throughout the study. However, both groups had a similar clinical benefit regarding renal function (improvement in 18.6 % vs. 19.1 %, and stabilization in 81.4 % vs. 80.9 % of patients in the EVR + rTAC vs. MMF + TAC groups, respectively). There were no significant differences in the incidence of acute rejection (5.7 % vs. 3.8 %), deaths (5.7 % vs. 2.8 %), and serious adverse events (51.9 % vs. 44.0 %) between the 2 groups. CONCLUSION: EVR + rTAC allows a safe reduction in tacrolimus exposure in de novo liver transplant recipients, with a significant improvement in eGFR but without significant differences in renal clinical benefit 1 year after liver transplantation.

A QTL for conformation of back and croup influences lateral gait quality in Icelandic horses.

BACKGROUND: The back plays a vital role in horse locomotion, where the spine functions as a spring during the stride cycle. A complex interaction between the spine and the muscles of the back contribute to locomotion soundness, gait ability, and performance of riding and racehorses. Conformation is commonly used to select horses for breeding and performance in multiple horse breeds, where the back and croup conformation plays a significant role. The conformation of back and croup plays an important role on riding ability in Icelandic horses. However, the genes behind this trait are still unknown. Therefore, the aim of this study was to identify genomic regions associated with conformation of back and croup in Icelandic horses and to investigate their effects on riding ability. One hundred seventy-seven assessed Icelandic horses were included in the study. A genome-wide association analysis was performed using the 670 K+ Axiom Equine Genotyping Array, and the effects of different haplotypes in the top associated region were estimated for riding ability and additional conformation traits assessed during breeding field tests. RESULTS: A suggestive quantitative trait loci (QTL) for the score of back and croup was detected on Equus caballus (ECA) 22 (p-value = 2.67 × 10- 7). Haplotype analysis revealed two opposite haplotypes, which resulted in higher and lower scores of the back and croup, respectively (p-value < 0.001). Horses with the favorable haplotype were more inclined to have a well-balanced backline with an uphill conformation and had, on average, higher scores for the lateral gaits tölt (p-value = 0.02) and pace (p-value = 0.004). This genomic region harbors three genes: C20orf85, ANKRD60 and LOC100056167. ANKRD60 is associated with body height in humans. C20orf85 and ANKRD60 are potentially linked to adolescent idiopathic scoliosis in humans. CONCLUSIONS: Our results show that the detected QTL for conformation of back and croup is of importance for quality of lateral gaits in Icelandic horses. These findings could result in a genetic test to aid in the selection of breeding horses, thus they are of major interest for horse breeders. The results may also offer a gateway to comparative functional genomics by potentially linking both motor laterality and back inclination in horses with scoliosis in humans.

Transthyretin amyloidosis with cardiomyopathy after domino liver transplantation: Results of a cross-sectional study.

Domino liver transplantation (DLT) has been used widely in patients with hereditary amyloid transthyretin (ATTR) amyloidosis. New-onset polyneuropathy in recipients of DLT has been reported, but there are few cases of cardiac involvement reported. We aimed to perform a cross-sectional study for ATTR amyloidosis with cardiomyopathy (ATTR-CM) in DLT recipients. We evaluated 23 living DLT recipients a median of 9 years since DLT at 2 referral centers with a systematic cardiac evaluation, including bone scintigraphy. Median age was 72 years, 91% had hypertension, 35% had diabetes mellitus, 67% had chronic renal failure, and 8 patients (35%) developed new-onset polyneuropathy. Only 13% had a normal electrocardiogram and a normal echocardiography, and most of them showed some conduction disturbance or increase in left ventricular wall thickness, but only 1 patient with a Glu89Lys mutation developed ATTR-CM diagnosed by bone scintigraphy and endomyocardial biopsy. None of the recipients of a DLT with Val30Met mutation showed cardiac involvement by bone scintigraphy. In conclusion, DLT from Val30Met donors seems to be safe regarding the development of ATTR-CM. Evaluation of cardiomyopathy in DLT recipients is challenging due to concomitant comorbidities and in this context, bone scintigraphy can be helpful to evaluate ATTR-CM.

Nursing interventions for perinatal bereavement care in neonatal intensive care units: A scoping review.

BACKGROUND: Despite technological advances and specialist training of neonatal teams, perinatal deaths still occur. Such events are traumatic experiences for the parents and increase the risk of pathological grieving. Nursing is one of the main sources of support. However, the important work of nurses in these situations is made more difficult by the lack of recognized strategies that can be implemented to assist parents and family members in the bereavement process. AIM: Identify nursing interventions to help parents of neonates admitted to neonatal intensive care units cope with perinatal loss. METHODS: A scoping review based on the methodological framework established by Arksey and O'Malley was used. A total of 327 relevant studies were identified through a bibliographic search in Pubmed, CINAHL Plus, APA PsycNET and Scopus between 2000 and 2019. The screening process included an initial analysis of the relevance of the abstract and, when required, an extensive review of the full paper. RESULTS: A total of 9 papers were finally selected which responded to the research question. All nine papers are from the USA and have different methodological characteristics. A number of effective interventions were identified, including legacy creation, support groups, family-centred accompaniment and follow-up, parental involvement in pre-mortem care, intergenerational bereavement programmes, and the use of technological and spiritual resources. CONCLUSION: In general, the scant evidence that is available about nursing interventions around perinatal bereavement care underlines the requirement to thoroughly assess the effectiveness of those that have already been designed and implemented. IMPLICATIONS FOR NURSING PRACTICE AND POLICY: This scoping review contributes to the potential implementation of effective interventions to deal with and help parents and family members cope with perinatal bereavement, with nursing staff as the main source of support and leading interventions which have family members in the care team. This review also makes a substantial contribution to the development of a practical and evidence-based clinical guide for nursing, with recommendations that can be adapted to effective quality care criteria. It is additionally intended to encourage visibility in health policies of care and attention to perinatal grief in neonatal intensive care units.

[National survey on the treatment of cholelitiasis in Spain during the initial period of the COVID-19 pandemic]. / Encuesta nacional sobre el tratamiento de la colelitiasis en España durante la fase inicial de la pandemia por COVID-19.

Introduction: The extraordinary impact of COVID-19 pandemic on Spanish hospitals has led to a redistribution of resources for the treatment of these patients, with a decreased capacity of care for other common diseases. The aim of the present study is to analyse how this situation has affected the treatment of cholecystitis and cholelythiasis. Methods: It is a descriptive national study after online voluntary distribution of a specific questionnaire with Google Drive™ to members of the Spanish Association of Surgeons (AEC). Results: We received 153 answers (one per hospital). Elective cholecystectomies have been cancelled in 96.7% of centres. Conservative treatment for acute cholecystitis has been selected in 90% (previously 18%), and if operated, 95% have been performed laparoscopically. Globally, only 49% perform preoperative diagnostic tests for SARS-CoV-2, and 58.5% recognize there have been cases confirmed postoperatively after other surgeries, with worse surgical outcomes in 54%. Conclusions: This survey shows that most of the Spanish centers are following the surgical societies suggestions during the pandemic. However, some data requires to be taken into account for the next phase of the pandemic.

Molecular Pathways Leading to Induction of Cell Death and Anti-Proliferative Properties by Tacrolimus and mTOR Inhibitors in Liver Cancer Cells.

BACKGROUND/AIMS: Orthotopic liver transplantation (OLT) is the recommended treatment for patients at early stages of hepatocarcinoma (HCC) with portal hypertension and/or increased bilirubinemia, but without vascular-associated diseases. Tumor recurrence, which is the main drawback for the survival of patients submitted to OLT for HCC, has been related to tumor-related variables and the immunosuppressive therapies. We have previously shown that Tacrolimus (FK506) exerts a more potent pro-apoptotic and anti-proliferative effects than the mammalian target of rapamycin (mTOR) inhibitors (Sirolimus and Everolimus) in liver cancer cells. This study identified the role of the immunosuppressant partners such as FK506-binding proteins (FKBPs) in the induction of cell death and arrest of cell proliferation by immunosuppressants in two representative liver cancer cells. METHODS: The regulation of endoplasmic reticulum (ER) stress, apoptosis/autophagy, cell proliferation, and FKBPs expression was determined in Tacrolimus-, Sirolimus- and Everolimus-treated primary human hepatocytes, and hepatoma HepG2 and Huh7 cell lines. The functional repercussion of FKBPs on cell death and proliferation was also addressed using the siRNA technology. The assessed antitumoral properties of the immunosuppressants were associated to microRNAs (miRNAs) pattern. RESULTS: The enhanced pro-apoptotic and anti-proliferative properties of Tacrolimus versus mTOR inhibitors were associated with increased protein kinase RNA-like endoplasmic reticulum kinase (PERK)-related ER stress, Ser15P-p53/p53 ratio and p21 protein expression that may counterbalance the risk of proliferative upregulation caused by enhanced Thr172P-Cdk4/Cdk4 activation in liver cancer cells. The inhibition of the mTOR pathway by Sirolimus and Everolimus was related to an induction of autophagy; and at a high dose, these drugs impaired translation likely at a very early step of the elongation phase. Tacrolimus and mTOR inhibitors increased the protein expression of FKBP12 and FKBP51 that appeared to play pro-survival role. Interestingly, the administration of immunosuppressants yields a specific pattern of miRNAs. Tacrolimus and mTOR inhibitors decreased miR-92a-1-5p, miR-197-3p, miR-483-3p and miR-720, and increased miR-22-3p, miR-376a-3p, miR-663b, miR-886-5p, miR-1300 and miR-1303 expressions in HepG2 cells. CONCLUSION: The more potent pro-apoptotic and anti-proliferative properties of Tacrolimus versus mTOR inhibitors were associated with an increased activation of PERK and p53 signaling, and p21 protein expression. FKBP12 and FKBP51 appeared to be the most relevant partners of Tacrolimus and mTOR inhibitors exerting a pro-survival effect in HepG2 cells. The observed effects of immunosuppressants were related to a specific miRNA signature in liver cancer cells.

Glutathione S-Transferase T1 Mismatch Is a Risk Factor for Chronic Ductopenic Rejection of Liver Allografts.

The underlying causes of chronic rejection (CR) after liver transplantation (LT) are not completely known. The main aim of this study was to explore the involvement of the minor histocompatibility antigen glutathione S-transferase T1 (GSTT1) in CR. We retrospectively studied 611 patients who underwent LTs at University Hospital Virgen del Rocío between 2003 and 2016 with a median follow-up of 7.4 ± 4.2 years. The GSTT1 genotype was determined by polymerase chain reaction. We defined GSTT1 mismatch as a specific donor/recipient combination in which a recipient who was homozygous for the deletion allele received a transplant from a positive donor. The prevalence of CR in our whole cohort was 11.6% (71/611), and the prevalence in the GSTT1-mismatched group was 18.8% (16/85) versus 10.5% (55/526) in the GSTT1-matched group. In the cyclosporine A (CsA) group, the prevalence was 26.3% (26/99), much higher than the 8.8% (45/512) observed in the tacrolimus (Tac) group. For statistical analysis, the patients were distributed into 2 groups: group 1, regarded as GSTT1 mismatched, which included the donor (D)+/recipient (R)- allelic combination; and group 2, regarded as GSTT1 matched, which included the other allelic combinations of D+/R+, D-/R-, and D-/R+. All relevant clinical information was collected, and a diagnosis of CR was always confirmed by liver biopsy. GSTT1 mismatch (hazard ratio [HR], 1.99; 95% confidence interval [CI], 1.08-3.66; P = 0.03) and use of CsA/Tac (P < 0.001) were independent risk factors for CR. CR increased the risk of mortality (HR, 2; 95% CI, 1.2-3.6; P = 0.01). Out of the 71 CR patients, 12 (16.9%) needed retransplantation. In conclusion, the GSTT1 D+/R- allelic mismatch is an independent risk factor for CR. A long follow-up of LT patients is recommended because the incidence of CR in adults seems to be underestimated.

The All but Forgotten Mascagni-Sappey Pathway: Learning from Immediate Lymphatic Reconstruction.

BACKGROUND: Upper extremity lymphedema occurs in 25 to 40% of patients after axillary lymph node dissection (ALND). Immediate lymphatic reconstruction (ILR) or the lymphatic micro- surgical preventative healing approach has demonstrated a significant decrease in postoperative rates of lymphedema (LE) from 4 to 12%. Our objective was to map the Mascagni -Sappey pathway, the lateral upper arm draining lymphatics, in patients undergoing ILR to better characterize the drainage pattern of this lymphosome to the axilla. METHODS: A retrospective review of our institutional lymphatic database was conducted and consecutive breast cancer patients undergoing ILR were identified from November 2017 through June 2018. Patient demographics, clinical characteristics, and intraoperative records were retrieved and analyzed. RESULTS: Twenty-nine consecutive breast cancer patients who underwent ILR after ALND were identified. Patients had a mean age of 54.6years and body mass index (BMI) of 26.6 kg/m2. Fluorescein isothiocyanate (FITC) was injected at the medial upper arm and isosulfan blue was injected at the cephalic vein, or lateral upper arm, prior to ALND. After ALND, an average 2.5 divided lymphatics were identified, and a mean 1.2 lymphatics were bypassed. In all patients, divided FITC lymphatics were identified. However, in only three patients (10%), divided blue lymphatics were identified after ALND. CONCLUSION: In this study, variable drainage of the lateral upper arm to the axillary bed was noted. This study is the first to provide a description of intraoperative findings, demonstrating variable drainage patterns of upper extremity lymphatics to the axilla. Moreover, we noted that the lateral- and medial-upper arm lymphosomes have mutually exclusive pathways draining to the axilla. Further study of lymphatic anatomy variability may elucidate the pathophysiology of lymphedema development and influence approaches to immediate lymphatic reconstruction.

Normothermic regional perfusion vs. super-rapid recovery in controlled donation after circulatory death liver transplantation.

BACKGROUND & AIMS: Although there is increasing interest in its use, definitive evidence demonstrating a benefit for postmortem normothermic regional perfusion (NRP) in controlled donation after circulatory death (cDCD) liver transplantation is lacking. The aim of this study was to compare results of cDCD liver transplants performed with postmortem NRP vs. super-rapid recovery (SRR), the current standard for cDCD. METHODS: This was an observational cohort study including all cDCD liver transplants performed in Spain between June 2012 and December 2016, with follow-up ending in December 2017. Each donor hospital determined whether organ recovery was performed using NRP or SRR. The propensity scores technique based on the inverse probability of treatment weighting (IPTW) was used to balance covariates across study groups; logistic and Cox regression models were used for binary and time-to-event outcomes. RESULTS: During the study period, there were 95 cDCD liver transplants performed with postmortem NRP and 117 with SRR. The median donor age was 56 years (interquartile range 45-65 years). After IPTW analysis, baseline covariates were balanced, with all absolute standardised differences <0.15. IPTW-adjusted risks were significantly improved among NRP livers for overall biliary complications (odds ratio 0.14; 95% CI 0.06-0.35, p <0.001), ischaemic type biliary lesions (odds ratio 0.11; 95% CI 0.02-0.57; p = 0.008), and graft loss (hazard ratio 0.39; 95% CI 0.20-0.78; p = 0.008). CONCLUSIONS: The use of postmortem NRP in cDCD liver transplantation appears to reduce postoperative biliary complications, ischaemic type biliary lesions and graft loss, and allows for the transplantation of livers even from cDCD donors of advanced age. LAY SUMMARY: This is a propensity-matched nationwide observational cohort study performed using livers recovered from donors undergoing cardiac arrest provoked by the intentional withdrawal of life support (controlled donation after circulatory death, cDCD). Approximately half of the livers were recovered after a period of postmortem in situ normothermic regional perfusion, which restored warm oxygenated blood to the abdominal organs, whereas the remainder were recovered after rapid preservation with a cold solution. The study results suggest that the use of postmortem normothermic regional perfusion helps reduce rates of post-transplant biliary complications and graft loss and allows for the successful transplantation of livers from older cDCD donors.

A Comparative Multimetric Assessment of English and Spanish Carpal Tunnel Syndrome Materials.

BACKGROUND: Spanish-speaking Hispanics living in the United States utilize the internet as a primary means to obtain health information. Accurate, accessible information is important for English speakers; however, it could have even greater utility for Spanish speakers who have lower health literacy levels. The aim of this study was to evaluate and compare online English and Spanish carpal tunnel surgery materials provided by using a multimetric approach. MATERIALS AND METHODS: A web search using the English term "carpal tunnel surgery" was performed. The first 10 institutional/organizational websites that provided carpal tunnel surgery information in English and Spanish were included. All relevant online materials were evaluated using the Patient Education and Materials Assessment Tool (PEMAT), Cultural Sensitivity Assessment Tool (CSAT), and Simplified Measure of Gobbledygook, Spanish (SOL) to assess understandability and actionability, cultural sensitivity, and readability, respectively. RESULTS: There were no statistically significant differences in understandability or actionability scores between Spanish and English materials. Average cultural sensitivity scores for Spanish materials were significantly lower than English materials (P = 0.015). The average reading grade level of online English materials was greater than that for Spanish materials (P = 0.011). Both mean values were above the recommended sixth-grade reading level. CONCLUSIONS: Online patient-directed information regarding carpal tunnel surgery exceeded the recommended reading grade level for both English and Spanish-speaking populations. Most Spanish materials were often direct translations and were not contoured to the elevated literacy needs of this demographic. Institutions must caution their authors to tailor their web material in a way that is sensitive to their target population to optimize understanding.

Point-of-care haemostasis monitoring during liver transplantation is cost effective.

Background Optimal haemostasis management in orthotropic liver transplant (OLT) could reduce blood loss and transfusion volume, improve patient outcomes and reduce cost. Methods We performed a study including 336 OLTs to evaluate the clinical and cost effectiveness of a new point-of-care (POC)-based haemostatic management approach in OLT patients. Results In terms of health benefit we found that the new approach showed a significant reduction in transfusion requirements (red blood cell transfusion units were reduced from 5.3±4.6 to 2.8±2.9 [p<0.001], free frozen plasma from 3.1±3.3 to 0.4±1.0 [p<0.001] and platelets from 2.9±3.9 to 0.4±0.9 [p<0.001], transfusion avoidance, 9.7% vs. 29.1% [p<0.001] and massive transfusion, 14.5% vs. 3.8% [p=0.001]); we also found a significant improvement in patient outcomes, such, reoperation for bleeding or acute-kidney-failure (8.3% vs. 2.4%, p=0.015; 33.6% vs. 5.4%, p<0.001), with a significant reduction in the length of the hospital total stay (40.6±13.8 days vs. 38.2±14.4 days, p=0.001). The lowest cost incurred was observed with the new approach (€73,038.80 vs. €158,912.90) with significant patient saving associated to transfusion avoidance (€1278.36), ICU-stay (€3037.26), total-stay (€3800.76) and reoperation for bleeding (€80,899.64). Conclusions POC haemostatic monitoring during OLT is cost effective.

Cultural Insensitivity Pervasive in Spanish Online Cosmetic Surgery Resources: A Call to Action.

BACKGROUND: Hispanics are the second largest demographic that underwent cosmetic surgery in 2017. The popularity of cosmetic surgeries among this group has increased significantly within the past decade and is projected to continue rising. Patient-directed websites that provide educational materials addressing these procedures should include information that is accurate, comprehensible, and sensitive to the demographic's diverse cultural and ethnic needs. Online health resources have been shown to vary significantly in their quality and reliability. This can be inimical for patients, as misinformation has been associated with poor health outcomes. The aim of this study is to evaluate online Spanish patient-directed materials for the top 5 cosmetic surgeries performed in 2017 using validated metrics. METHODS: The top 5 cosmetic surgeries performed in 2017 according to the American Society of Plastic Surgeons were identified, and a Google search was performed using the following terms: "breast augmentation," "liposuction," "rhinoplasty," "blepharoplasty," and "abdominoplasty." The top 10 websites providing relevant information in Spanish were identified for each procedure. Fifty unique web links were analyzed by 2 independent bilingual raters using the Cultural Sensitivity Assessment Tool, and mean reading grade level was determined. Interrater reliability was computed using a Cohen κ. RESULTS: Online information in Spanish was difficult to encounter, with an average of 130 websites evaluated to identify 10 websites for each surgery. The mean reading grade level of all evaluated pages was 10.19, appropriate for a high school sophomore. There were no statistically significant differences between cosmetic surgery procedures (P = 0.69). The mean cultural sensitivity score was 2.20 (2.08-2.38). No subgroup met the threshold score for acceptable cultural sensitivity of >2.5. CONCLUSION: This study demonstrates that US websites do not offer appropriate-level Spanish materials for patients seeking information on cosmetic surgeries. Websites providing information in Spanish were often inaccurate automatic translations and further compromised reader understanding. In our search, we frequently encountered organizational statements expressing a commitment to diversity. Increased awareness and development of more culturally appropriate materials is paramount to effectively communicate with patients and begin to close the gap in cultural disparities in health literacy.
