Liver transplantation for "very early" intrahepatic cholangiocarcinoma: International retrospective study supporting a prospective assessment.

UNLABELLED: The presence of an intrahepatic cholangiocarcinoma (iCCA) in a cirrhotic liver is a contraindication for liver transplantation in most centers worldwide. Recent investigations have shown that "very early" iCCA (single tumors ≤2 cm) may have acceptable results after liver transplantation. This study further evaluates this finding in a larger international multicenter cohort. The study group was composed of those patients who were transplanted for hepatocellular carcinoma or decompensated cirrhosis and found to have an iCCA at explant pathology. Patients were divided into those with "very early" iCCA and those with "advanced" disease (single tumor >2 cm or multifocal disease). Between January 2000 and December 2013, 81 patients were found to have an iCCA at explant; 33 had separate nodules of iCCA and hepatocellular carcinoma, and 48 had only iCCA (study group). Within the study group, 15/48 (31%) constituted the "very early" iCCA group and 33/48 (69%) the "advanced" group. There were no significant differences between groups in preoperative characteristics. At explant, the median size of the largest tumor was larger in the "advanced" group (3.1 [2.5-4.4] versus 1.6 [1.5-1.8]). After a median follow-up of 35 (13.5-76.4) months, the 1-year, 3-year, and 5-year cumulative risks of recurrence were, respectively, 7%, 18%, and 18% in the very early iCCA group versus 30%, 47%, and 61% in the advanced iCCA group, P = 0.01. The 1-year, 3-year, and 5-year actuarial survival rates were, respectively, 93%, 84%, and 65% in the very early iCCA group versus 79%, 50%, and 45% in the advanced iCCA group, P = 0.02. CONCLUSION: Patients with cirrhosis and very early iCCA may become candidates for liver transplantation; a prospective multicenter clinical trial is needed to further confirm these results.

Average treatment effect of hepatic resection versus locoregional therapies for hepatocellular carcinoma.

BACKGROUND: When comparing the efficacy of surgical and non-surgical therapies for hepatocellular carcinoma (HCC), a major limitation is the causal inference problem. This concerns the impossibility of seeing both outcomes of two different treatments for the same individual at the same time because one is inevitably missing. This aspect can be addressed methodologically by estimating the so-called average treatment effect (ATE). METHODS: To estimate the ATE of hepatic resection over locoregional therapies for HCC, data from patients treated in two tertiary care settings between August 2000 and December 2014 were used to obtain counterfactual outcomes using an inverse probability weight survival adjustment. RESULTS: A total of 1585 patients were enrolled: 815 underwent hepatic resection, 337 radiofrequency ablation (RFA) and 433 transarterial chemoembolization (TACE). The option of operating on all patients who had tumour ablation returned an ATE of +9·8 months for resection (effect size 0·111; adjusted P = 0·064). The option of operating on all patients who had TACE returned an ATE of +27·9 months (effect size 0·383; adjusted P < 0·001). The ATE of surgery was negligible in patients undergoing ablation for very early HCCs (effect size 0·027; adjusted P = 0·627), independently of albumin-bilirubin (ALBI) grade; or in patients with ALBI liver function grade 2 (effect size 0·083; adjusted P = 0·213), independently of tumour stage. In all other instances, the ATE of surgery was notably greater. Operating on patients who had TACE with multinodular HCC beyond the Milan criteria resulted in a mild ATE (effect size 0·140; adjusted P = 0·037). CONCLUSION: ATE estimation suggests that hepatic resection is a better treatment option than ablation and TACE in patients with HCC.

Impact of preoperative infection on outcome after liver transplantation.

BACKGROUND: Bacterial infection in patients with liver failure can lead to a dramatic clinical deterioration. The indications for liver transplantation and outcome in these patients is still controversial. METHODS: All adult patients who underwent liver transplantation between 1 January 2010 and 31 December 2015 were selected from an institutional database. Characteristics of the donors and recipients, and clinical, biochemical and surgical parameters were retrieved from the database. Post-transplant survival rates and complications, including grade III-IV complications according to the Dindo-Clavien classification, were compared between patients with an infection 1 month before transplantation and patients without an infection. RESULTS: Eighty-four patients with an infection had statistically significant higher Model for End-stage Liver Disease (MELD), D-MELD and Balance of Risk (BAR) scores and a higher rate of acute-on-chronic liver failure compared with findings in 343 patients with no infection. The rate of infection after liver transplantation was higher in patients who had an infection before the operation: 48 per cent versus 30·6 per cent in those with no infection before transplantation (P = 0·003). The percentage of patients with a postoperative complication (42 versus 40·5 per cent respectively; P = 0·849) and the 90-day mortality rate (8 versus 6·4 per cent; P = 0·531) was no different between the groups. Multivariable analysis showed that a BAR score greater than 18 and acute-on-chronic liver failure were independent predictors of 90-day mortality. CONCLUSION: Bacterial infection 1 month before liver transplantation is related to a higher rate of infection after transplantation, but does not lead to a worse outcome.

Cerium oxide nanoparticles (CeO2 NPs) improve the developmental competence of in vitro-matured prepubertal ovine oocytes.

The present study investigated whether supplementation with different doses of cerium dioxide nanoparticles (CeO2 NPs) during in vitro maturation (IVM) of prepubertal ovine oocytes influenced their embryonic development in vitro. Cumulus-oocyte complexes derived from the ovaries of slaughtered prepubertal sheep underwent IVM with CeO2NPs (0, 44, 88 or 220µg mL-1). Matured oocytes were fertilised in vitro and zygotes were cultured for 7 days. The results demonstrated that CeO2NPs were internalised in the cumulus cells and not in the oocyte. The treatment with CeO2NPs did not affect nuclear maturation or intracellular levels of reactive oxygen species of the oocytes. The percentage of oocytes with regular chromatin configuration and cytoskeleton structures when treated with 44µg mL-1 CeO2NPs was similar to oocytes matured in the absence of CeO2NPs and significantly higher than those treated with 88 or 220µg mL-1 CeO2NPs. The relative quantification of transcripts in the cumulus cells of oocytes matured with 44µg mL-1 CeO2NPs showed a statistically lower mRNA abundance of BCL2-associated X protein (BAX), B-cell CLL/lymphoma 2 (BCL2) and superoxide dismutase 1 (SOD1) compared with the 0µg mL-1 CeO2 NPs group. A concentration of 44µg mL-1 CeO2NPs significantly increased the blastocyst yield and their total, inner cell mass and trophectoderm cell numbers, compared with the 0 and 220µg mL-1 groups. A low concentration of CeO2NPs in the maturation medium enhanced in vitro embryo production of prepubertal ovine oocytes.

Bullous morphoea: a retrospective study.

Bullous morphoea is a rare variant of localized scleroderma whose pathogenesis has been widely discussed. We retrospectively reviewed the records of all histopathologically confirmed cases of morphoea followed from 2005 to 2015 at the Dermatology Clinic and Pathology Institute of the University of Cagliari, Sardinia, Italy. Among 137 patients with morphoea, 2 cases of the bullous variant were identified, which were successfully treated with methotrexate. Thus, the bullous form comprised 1.4% of all cases of morphoea, which is much lower than the 7.5% previously reported. In one of the cases, histopathological examination revealed a peculiar 'stretching' pattern of basal keratinocytes attached to the epidermal roof of the bulla, together with increased lymphatic vessels, which were either collapsed or dilated, stressing the role of lymphatics and possibly of excessive skin trauma and friction in the development of bullous lesions.

Reconnection surgery in adult post-operative short bowel syndrome < 100 cm: is colonic continuity sufficient to achieve enteral autonomy without autologous gastrointestinal reconstruction? Report from a single center and systematic review of literature.

A systematic bibliographic research concerning patients operated on for SBS was performed: inclusion criteria were adult age, reconnection surgery and SBS < 100 cm. Autologous gastrointestinal reconstruction represented an exclusion criteria. The outcomes of interest were the rate of total parenteral nutrition (TPN) independence and the length of follow-up (minimum 1 year) after surgery. We reviewed our experience from 2003 to 2013 with minimum 1-year follow-up, dealing with reconnection surgery in 13 adults affected by < 100 cm SBS after massive small bowel resection: autologous gastrointestinal reconstruction was not feasible. Three (out of 5168 screened papers) non randomized controlled trials with 116 adult patients were analysed showing weaning from TPN (40%, 50% and 90% respectively) after reconnection surgery without autologous gastrointestinal reconstruction. Among our 13 adults, mean age was 54.1 years (53.8 % ASA III): 69.2 % had a high stomal output (> 500 cc/day) and TPN dependence was 100%. We performed a jejuno-colonic anastomosis (SBS type II) in 53.8%, in 46.1% of cases without ileo-cecal valve, leaving a mean residual small bowel length of 75.7 cm. In-hospital mortality was 0%. After a minimum period of 1 year of intestinal rehabilitation, all our patients (100%) went back to oral intake and 69.2% were off TPN (9 patients). No one was listed for transplantation. A residual small bowel length of minimum 75 cm, even if reconnected to part of the colon, seems able to produce a TPN independence without autologous gastrointestinal reconstruction after a minimum period of 1 year of intestinal rehabilitation.

Surgery for post-operative entero-cutaneous fistulas: is bowel resection plus primary anastomosis without stoma a safe option to avoid early recurrence? Report on 20 cases by a single center and systematic review of the literature.

BACKGROUND: A review was performed on entero-cutaneous fistula (ECF) repair and early recurrence, adding our twenty adult patients (65% had multiple fistulas). METHODS: The search yielded 4.098 articles but only 15 were relevant: 1.217 patients underwent surgery. The interval time between fistula's diagnosis and operative repair was between 3 months and 1 year. A bowel resection with primary anastomosis was performed in 1.048 patients, 192 (18.3%) underwent a covering stoma: 856 patients (81.7%) had a fistula takedown in one procedure. RESULTS: The patients had 14.3% recurrence and 13.1% mortality rate. In our experience 75% were surgically treated after a period equal or above one year from fistula occurrence: surgery was very demolitive (in 40% remnant small bowel was less than 100 cm). We performed a bowel resection with a hand-sewn anastomosis (95%) without temporary stoma. In-hospital mortality was 0% and at discharge all were back to oral intake with 0% early re-fistulisation. CONCLUSIONS: Literature supports our experience: ECF takedown could be safely performed after an adequate period of recovery from 3 months to one year from fistula occurrence. In our series primary repair (bowel resection plus reconnection surgery without temporary stoma) avoided an early recurrence without mortality.

Effect of age on survival in patients undergoing resection of hepatocellular carcinoma.

BACKGROUND: The benefit of surgical intervention for cancer should be estimated in relation to the life expectancy of the general population. The aim of this study was to provide a measure of relative survival after hepatectomy for hepatocellular carcinoma (HCC). METHODS: Consecutive patients with liver cirrhosis and HCC who underwent hepatectomy were divided into age quartiles for analysis. Short- and mid-term survival rates were used to estimate survival until death for all patients, in relation to age and other co-variables. Years of life lost (YLL) were estimated using a reference cohort, derived from the general population matched for sex, age and year of diagnosis. RESULTS: Some 919 patients were included in the study. The following age quartiles were identified: less than 60 years (229 patients), 60-66 years (230), 67-70 years (231) and over 70 years (229). Postoperative mortality rates were similar between age quartiles, as were survival rates up to 3 years (P = 0·404). A statistically significant reduction in 5-10-year survival rates was observed with ageing (P = 0·001). Relative survival calculation showed that the youngest age quartile (less than 60 years) experienced the longest entire postoperative lifespan (15·6 years) but also the greatest number of YLL (11·0 years). Patients aged over 70 years had the shortest entire postoperative lifespan (6·4 years) but also the smallest number of YLL (3·7 years). CONCLUSION: Although survival after liver resection for HCC is shortest in elderly patients, relative survival estimates suggest that hepatectomy can be of benefit in these patients, with a small loss of the entire individual lifespan.

Antifungal prophylaxis in liver transplant recipients: one size does not fit all.

BACKGROUND: Targeted antifungal prophylaxis against Candida species or against Candida species and Aspergillus species, according to individual patient risk factors (RFs), is recommended by experts. However, recent studies have reported fluconazole is as effective as broader spectrum antifungals for preventing invasive fungal infection (IFI) after liver transplantation (LT). METHODS: We performed a retrospective cohort study of all adult patients who underwent LT at our 1420-bed tertiary teaching hospital, from June 2010 to December 2014, to assess the rate and etiology of IFI within 100 days after LT, to investigate the compliance with targeted prophylaxis, and to analyze risk factors for developing IFI. RESULTS: In total, 303 patients underwent LT. Patients were classified as having low (no RFs), intermediate (1 RF for invasive candidiasis [IC]), and high risk (1 RF for invasive aspergillosis [IA] or ≥2 RFs for IC) for IFI in 20%, 30%, and 50% of cases, respectively. A total of 139 patients received antifungal prophylaxis: 98 with a mold-active drug and 41 with fluconazole. Overall adherence to targeted prophylaxis was 53%. Nineteen patients (6.3%) developed IFI: 7 IC and 12 IA. Multivariate Cox regression analysis, adjusted for median model for end-stage liver disease score at LT, stratification risk group, and adherence to targeted prophylaxis, showed that graft dysfunction, renal replacement therapy, and prophylaxis with fluconazole were independent risk factors for IFI. Seven of the 9 patients who received fluconazole prophylaxis and developed IFI were classified as having high risk for IFI, and 6 developed IA. CONCLUSION: Recommended stratification is accurate for predicting patients at very high risk for IFI, who should receive prophylaxis with a mold-active drug.

A Multistep, Consensus-Based Approach to Organ Allocation in Liver Transplantation: Toward a "Blended Principle Model".

Since Italian liver allocation policy was last revised (in 2012), relevant critical issues and conceptual advances have emerged, calling for significant improvements. We report the results of a national consensus conference process, promoted by the Italian College of Liver Transplant Surgeons (for the Italian Society for Organ Transplantation) and the Italian Association for the Study of the Liver, to review the best indicators for orienting organ allocation policies based on principles of urgency, utility, and transplant benefit in the light of current scientific evidence. MELD exceptions and hepatocellular carcinoma were analyzed to construct a transplantation priority algorithm, given the inequity of a purely MELD-based system for governing organ allocation. Working groups of transplant surgeons and hepatologists prepared a list of statements for each topic, scoring their quality of evidence and strength of recommendation using the Centers for Disease Control grading system. A jury of Italian transplant surgeons, hepatologists, intensivists, infectious disease specialists, epidemiologists, representatives of patients' associations and organ-sharing organizations, transplant coordinators, and ethicists voted on and validated the proposed statements. After carefully reviewing the statements, a critical proposal for revising Italy's current liver allocation policy was prepared jointly by transplant surgeons and hepatologists.

Risk factors for infection with carbapenem-resistant Klebsiella pneumoniae after liver transplantation: the importance of pre- and posttransplant colonization.

Improved understanding of risk factors associated with carbapenem-resistant-Klebsiella pneumoniae (CR-KP) infection after liver transplantation (LT) can aid development of effective preventive strategies. We performed a prospective cohort study of all adult patients undergoing LT at our hospital during 30-month period to define risk factors associated with CR-KP infection. All patients were screened for CR-KP carriage by rectal swabs before and after LT. No therapy was administered to decolonize or treat asymptomatic CR-KP carriers. All patients were monitored up to 180 days after LT. Of 237 transplant patients screened, 41 were identified as CR-KP carriers (11 at LT, 30 after LT), and 20 developed CR-KP infection (18 bloodstream-infection, 2 pneumonia) a median of 41.5 days after LT. CR-KP infection rates among patients non-colonized, colonized at LT, and colonized after LT were 2%, 18.2% and 46.7% (p < 0.001). Independent risk factors for CR-KP infection identified by multivariate analysis, included: renal-replacement-therapy; mechanical ventilation > 48 h; HCV recurrence, and colonization at any time with CR-KP. Based on these four variables, we developed a risk score that effectively discriminated patients at low versus higher risk for CR-KP infection (AUC 0.93, 95% CI 0.86-1.00, p < 0.001). Our results may help to design preventive strategies for LT recipients in CR-KP endemic areas.

Meta-analysis of the effect of preoperative breast MRI on the surgical management of ductal carcinoma in situ.

BACKGROUND: MRI has been used increasingly in the diagnosis and management of women with invasive breast cancer. However, its usefulness in the preoperative assessment of ductal carcinoma in situ (DCIS) remains questionable. A meta-analysis was conducted to examine the effects of MRI on surgical treatment of DCIS by analysing studies comparing preoperative MRI with conventional preoperative assessment. METHODS: Using random-effects modelling, the proportion of women with various outcomes in the MRI versus no-MRI groups was estimated, and the odds ratio (OR) and adjusted OR (adjusted for study-level median age) for each model were calculated. RESULTS: Nine eligible studies were identified that included 1077 women with DCIS who had preoperative MRI and 2175 who did not. MRI significantly increased the odds of having initial mastectomy (OR 1·72, P = 0·012; adjusted OR 1·76, P = 0·010). There were no significant differences in the proportion of women with positive margins following breast-conserving surgery (BCS) in the MRI and no-MRI groups (OR 0·80, P = 0·059; adjusted OR 1·10, P = 0·716), nor in the necessity of reoperation for positive margins after BCS (OR 1·06, P = 0·759; adjusted OR 1·04, P = 0·844). Overall mastectomy rates did not differ significantly according to whether or not MRI was performed (OR 1·23, P = 0·340; adjusted OR 0·97, P = 0·881). CONCLUSION: Preoperative MRI in women with DCIS is not associated with improvement in surgical outcomes.

Granulomatous reactions after injections of multiple aesthetic micro-implants in temporal combinations: a complication of filler addiction.

BACKGROUND: Granulomatous reaction is a well-known complication following soft filler procedures. However, the diagnosis of filler-induced granulomas may be challenging because of the occasional reluctance of patients to report the previously performed aesthetic procedure. OBJECTIVE: To describe a new clinical situation in which some patients, in the quest for physical perfection, become addicted to multiple sequential cosmetic injections, increasing the risk of adverse reactions. METHODS: We describe three women who developed diffuse facial nodular tumefaction after multiple procedures of filler injections into their face that occurred at different times in the previous years. RESULTS: Histopathology showed a granulomatous reaction including different combined substances that were identified with different types of micro-implants in the same biopsy. CONCLUSIONS: Excessive demand of multiple cosmetic injections may increase the frequency of skin granulomatous reactions and can be included in the spectrum of similar addictive dysmorphophobic behaviours. Histopathology is the best mean to achieve the diagnosis.

Diffuse dermal angiomatosis: a clinical mimicker of vasculitis associated with calciphylaxis and monoclonal gammopathy.

Diffuse dermal angiomatosis is a form of cutaneous reactive angiomatosis characterized clinically by painful erythematous or violaceous lesions with ulcers that may mimic cutaneous vasculitis/vasculopathy. Histologically it shows a benign, diffuse proliferation of endothelial cells with tiny blood vessels in the papillary and reticular dermis. Herein, we report four patients with diffuse dermal angiomatosis in the setting of calciphylaxis and monoclonal gammopathy and review the cases previously published in the literature. Comorbidities and management will also be discussed.

Imaging in resectable colorectal liver metastasis patients with or without preoperative chemotherapy: results of the PROMETEO-01 study.

BACKGROUND: The aim of the PROMETEO-01 Study was to define the diagnostic accuracy of imaging techniques in colorectal cancer liver metastasis (CRCLM) patients. METHODS: Patients referred to Bologna S. Orsola-Malpighi Hospital performed a computed-tomography scan (CT), magnetic resonance (MR), 18F-FDG-PET/CTscan (PET/CT) and liver contrast-enhanced-ultrasound (CEUS); CEUS was also performed intraoperatively (i-CEUS). Every pathological lesion was compared with imaging data. RESULTS: From December 2007 to August 2010, 84 patients were enrolled. A total of 51 (60.71%) resected patients were eligible for analysis. In the lesion-by-lesion analysis 175 resected lesions were evaluated: 67(38.3%) belonged to upfront resected patients (group-A) and 108 (61.7%) to chemotherapy-pretreated patients (group-B). In all patients the sensitivity of MR proved better than CT (91% vs 82%; P=0.002), CEUS (91 vs 81%; P=0.008) and PET/CT (91% vs 60%; P=0.000), whereas PET/CT showed the lowest sensitivity. In group-A the sensitivity of i-CEUS, MR, CT, CEUS and PET/CT was 98%, 94%, 91%, 84% and 78%, respectively. In group-B the i-CEUS proved equivalent in sensitivity to MR (95% and 90%, respectively, P=0.227) and both were significantly more sensitive than other procedures. The CT sensitivity in group-B was lower than in group-A (77% vs 91%, P=0.024). CONCLUSIONS: A thoraco-abdominal CT provides an adequate baseline evaluation and guides judgment as to the resectability of CRCLM patients. In the subset of candidates for induction chemotherapy to increase the chance of liver resection, the most rational approach is to add MR for the staging and restaging of CRCLM.

Is resectable hepatocellular carcinoma a contraindication to liver transplantation? A novel decision model based on "number of patients needed to transplant" as measure of transplant benefit.

BACKGROUND & AIMS: Number-needed-to-treat is used in assessing the effectiveness of a health-care intervention, and reports the number of patients who need to be treated to prevent one additional bad outcome. Although largely used in medical literature, there are no studies measuring the benefit of liver transplantation (LT) over hepatic resection (HR) for hepatocellular carcinoma (HCC) in terms of "Number of patients needed to transplant (NTT)." EXCLUSION CRITERIA: Child-Turcotte-Pugh (CTP) Classes B-C, very large (>10 cm) and multi-nodular (>2 nodules) tumours, macroscopic vascular invasion and extra-hepatic metastases. STUDY POPULATION: 1028 HCC cirrhotic patients from one Eastern (n=441) and two Western (n=587) surgical units. Patient survival observed after HR by proportional hazard regression model was compared to that predicted after LT by the Metroticket calculator. The benefit obtainable from LT compared to resection was analysed in relationship with number of nodules (modelled as ordinal variable: single vs. oligonodular), size of largest nodule (modelled as a continuous variable), presence of microscopic vascular invasion (MVI), and time horizon from surgery (5-year vs. 10-year). RESULTS: 330 patients were beyond the Milan criteria (32%) and 597 (58%) had MVI. The prevalence of MVI was 52% in patients within Milan criteria and 71% in those beyond (p<0.0001). In the 5-year transplant benefit analysis, nodule size and HCC number were positive predictors of transplant benefit, while MVI had a strong negative impact on NTT. Transplantation performed as an effective therapy (NTT <5) only in oligonodular HCC with largest diameter >3cm (beyond conventional LT criteria) when MVI was absent. The 10-year scenario increased drastically the transplant benefit in all subgroups of resectable patients, and LT became an effective therapy (NTT <5) for all patients without MVI whenever tumor extension and for oligonodular HCC with MVI within conventional LT criteria. CONCLUSIONS: Based on NTT analysis, the adopted time horizon (5-year vs. 10-year scenario) is the main factor influencing the benefit of LT in patients with resectable HCC and Child A cirrhosis.

Induction therapy in adult intestinal transplantation: reduced incidence of rejection with "2-dose" alemtuzumab protocol.

The incidence of early rejection after intestinal transplantation correlates with heightened risk of graft loss and mortality. Many different induction or pre-conditioning protocols have been reported in the last 10 yr to improve outcomes; however, sepsis remains prevalent and diminishes long-term results. We recently began a "2-dose" alemtuzumab trial protocol - 15 mg at day 0 and 15 mg repeated on day 7 - with the hope of reducing our infection rate. We compared three different protocols used at our institution (daclizumab, conventional "4-dose" alemtuzumab, and "2-dose" alemtuzumab). There was a significantly lower rate of early rejection with the "2-dose" alemtuzumab protocol in our study group of mainly (88%) intestinal grafts without accompanying liver engraftment with its protective immunologic effect. Sepsis remained low. Longer follow-up will be required to evaluate the effects of this new protocol on longer-term outcomes.

Influence of seroreactivity to leptospira and reproductive failures in recipient mares of equine embryo transfer programmes.

The aim of this study was to demonstrate that seroreactivity against Leptospira is significantly associated to the reproductive efficiency of recipient mares of an embryo transfer (ET) programme. A serosurvey was conducted from August 2007 to March 2009 in five herds from Rio de Janeiro, Brazil, with high rates of reproductive failure, as early embryonic death (>12%), abortion (>12%) and perinatal death. Detailed information about the losses was obtained from practitioner. A total of 338 recipient mares were tested by microscopic agglutination test, and 226 (66.9%) were seroreactive, mainly against serovars Bratislava and Copenhageni. Seroreactivity could be associated to reproductive failure (p < 0.001), and it was demonstrated that a seroreactive mare is 1.8 times more likely (relative risk - RR) to present reproductive failure than a seronegative one, particularly in relation to early embryonic death (p < 0.0001; RR 8.4) but also to abortions (p < 0.0001; RR 3.5), and to perinatal death (p < 0.05; RR 7.3). Therefore, seroreactivity to Leptospira is associated to reproductive failure in all phases of pregnancy in recipient mares, impairing equine ET programmes.

Assessment of quality of life on home parenteral nutrition and after intestinal transplantation using treatment-specific questionnaires.

In order to investigate the quality of life on home parenteral nutrition and after intestinal transplantation using comparable questionnaires, the treatment-specific quality of life questionnaire for adult patients on home parenteral nutrition was adapted for intestinal transplant recipients. Both instruments were composed of 8 functional scales, 9 symptom scales, 3 global health status/quality of life scales and 2 single items. A preliminary cross-sectional study enrolling all the patients currently cared at the same hospital was carried out. Exclusion criteria were age ≥ 60 years and hospitalization at time of assessment. Thirty-three home parenteral nutrition patients (100% answered) and 22 intestinal transplant recipients (82% answered) were enrolled. Intestinal transplant recipients showed a better score in following scales: ability to holiday/travel (p < 0.001), fatigue (p = 0.022), gastrointestinal symptoms (p < 0.001), stoma management/bowel movements (p = 0.001) and global health status/quality of life (p = 0.012). A better score for ability to eat/drink (p = 0.070) and a worse score for sleep pattern (p = 0.100) after intestinal transplantation were also observed. The results of this preliminary study with specific instruments were consistent with the main expected improvement of the quality of life related to intestinal transplantation. Further studies in larger patient cohorts are required to confirm these data.

Patients' quality of life after allogeneic haematopoietic stem cell transplantation: mixed-methods study.

Allogeneic haematopoietic stem cell transplantation (HSCT) is an increasingly widespread therapy method. It is associated with many socio-psychological and physical risks. Forty-four subjects, who were clinically monitored at the Bolzano BMT Centre including a follow-up period of at least 3 months, completed the questionnaire Functional Assessment of Chronic Illness Therapy-Bone Marrow Transplantation (version 4). Semi-structured, problem-oriented interviews were conducted with seven randomly selected subjects, the results of which were subjected to a summarising content analysis according to Mayring. The results from the quantitative and qualitative parts were compared based on triangulation. In the random sample, 22.7% stated that they were highly satisfied with their current quality of life (QOL). Throughout all dimensions of the questionnaire, women showed lower scores than men. The results revealed a positive correlation between the post-HSCT period and QOL (r(s)=0.338, P=0.025), especially regarding the social/family (r(s)=0.411, P=0.006) and emotional well-being (r(s)=0.306, P=0.043). The interviews primarily revealed dependence and inability to work. The support received from family, friends and hospital staff and the shift in priorities because of the transplantation were perceived as positive. The comparison mainly leads to corresponding results of the quantitative and qualitative parts of the study. Patient self-rating using questionnaires and interviews plays a direct and relevant role in the assessment of the QOL after allogeneic HSCT.
