Abstract
OBJECTIVES In patients undergoing heart transplantation (HTX), preoperative liver impairment and consecutive hypoalbuminaemia are associated with increased mortality. The role of early postoperative hypoalbuminaemia after HTX is unclear. This study investigated the association between early postoperative hypoalbuminaemia and 1-year mortality as well as 'days alive and out of hospital' (DAOH) after HTX. METHODS This retrospective cohort study included patients who underwent HTX at the University Hospital Duesseldorf, Germany, between 2010 and 2022. The main exposure was serum albumin concentration at intensive care unit (ICU) arrival. The primary endpoints were mortality and DAOH within 1 year after surgery. Receiver operating characteristic (ROC) curve analysis was performed and logistic and quantile regression models with adjustment for 13 a priori defined clinical risk factors were conducted. RESULTS Out of 241 patients screened, 229 were included in the analysis (mean age 55 ± 11 years, 73% male). ROC analysis showed moderate discrimination for 1-year mortality by postoperative serum albumin after HTX [AUC = 0.74; 95% confidence interval (CI): 0.66-0.83]. The cutoff for serum albumin at ICU arrival was 3.0 g/dl. According to multivariate logistic and quantile regression, there were independent associations between hypoalbuminaemia and mortality/DAOH [odds ratio of 4.76 (95% CI: 1.94-11.67) and regression coefficient of -46.97 (95% CI: -83.81 to -10.13)]. CONCLUSIONS Postoperative hypoalbuminaemia <3.0 g/dl is associated with 1-year mortality and reduced DAOH after HTX and therefore might be used for early postoperative risk re-assessment in clinical practice.

Abstract
BACKGROUND In recent years, there has been increasing focus on the use of cardiac biomarkers in patients undergoing noncardiac surgery. AIMS The aim of this focused guideline was to provide updated guidance regarding the pre-, post- and combined pre-and postoperative use of cardiac troponin and B-type natriuretic peptides in adult patients undergoing noncardiac surgery. METHODS The guidelines were prepared using Grading of Recommendations Assessment Development and Evaluation (GRADE) methodology. This included the definition of critical outcomes, a systematic literature search, appraisal of certainty of evidence, evaluation of biomarker measurement in terms of the balance of desirable and undesirable effects including clinical outcomes, resource use, health inequality, stakeholder acceptance, and implementation. The panel differentiated between three different scopes of applications: cardiac biomarkers as prognostic factors, as tools for risk prediction, and for biomarker-enhanced management strategies. RESULTS In a modified Delphi process, the task force defined 12 critical outcomes. The systematic literature search resulted in over 25,000 hits, of which 115 full-text articles formed the body of evidence for recommendations. The evidence appraisal indicated heterogeneity in the certainty of evidence across critical outcomes. Further, there was relevant gradient in the certainty of evidence across the three scopes of application. Recommendations were issued and if this was not possible due to limited evidence, clinical practice statements were produced. CONCLUSION The ESAIC focused guidelines provide guidance on the perioperative use of cardiac troponin and B-type natriuretic peptides in patients undergoing noncardiac surgery, for three different scopes of application.

Abstract
BACKGROUND Orthotopic heart transplantation (HTX) is the gold standard to treat end-stage heart failure. Numerous risk stratification tools have been developed in the past years. However, their clinical utility is limited by their poor discriminative ability. High sensitivity troponin T (hsTnT) is the most specific biomarker to detect myocardial cell injury. However, its prognostic relevance after HTX is not fully elucidated. Thus, this study evaluated the predictive value of postoperative hsTnT for 1-year survival and days alive and out of hospital (DAOH) after HTX. METHODS This retrospective cohort study included patients who underwent HTX at the University Hospital Duesseldorf, Germany between 2011 and 2021. The main exposure was hsTnT concentration at 48 h after HTX. The primary endpoints were mortality and DAOH within 1 year after surgery. Receiver operating characteristic (ROC) curve analysis, logistic regression model and linear regression with adjustment for risk index for mortality prediction after cardiac transplantation (IMPACT) were performed. RESULTS Out of 231 patients screened, 212 were included into analysis (mean age 55 ± 11 years, 73% male). One-year mortality was 19.7% (40 patients) and median DAOH was 298 days (229-322). ROC analysis revealed strongest discrimination for mortality by hsTnT at 48 h after HTX [AUC = 0.79 95% CI 0.71-0.87]. According to Youden Index, the cutoff for hsTnT at 48 h and mortality was 1640 ng/l. After adjustment for IMPACT score multivariate logistic and linear regression showed independent associations between hsTnT and mortality/DAOH with odds ratio of 8.10 [95%CI 2.99-21.89] and unstandardized regression coefficient of -1.54 [95%CI -2.02 to -1.06], respectively. CONCLUSION Postoperative hsTnT might be suitable as an early prognostic marker after HTX and is independently associated with 1-year mortality and poor DAOH.

Abstract
BACKGROUND The number of patients treated with extracorporeal membrane oxygenation (ECMO) devices is increasing. Anticoagulation therapy is crucial to prevent thrombosis during ECMO therapy. Predominantly, heparin has been used as primary anticoagulant but direct thrombin inhibitors (DTI) have been established as alternatives. The aim of this systematic review and meta-analysis was to evaluate clinical outcomes in patients treated with heparin compared to different DTI during ECMO. METHODS A systematic search was conducted. Full scientific articles were sought for inclusion if heparin anticoagulation was compared to DTI (argatroban/bivalirudin) in ECMO patients. Risk of bias was assessed by Newcastle Ottawa scale. Primary endpoint was in-hospital mortality. Bleeding events, thrombotic events, hours of ECMO support, days of hospital stay, percentage of time within therapeutic range and time to therapeutic range were extracted from full texts as secondary endpoints. Results were presented as Forrest-plots. GRADE was used for confidence assessment in outcomes. RESULTS Systematic search identified 4.385 records, thereof 18 retrospective studies for a total of 1942 patients, complied with the predefined eligibility criteria:15 studies investigated bivalirudin and 3 studies investigated argatroban versus heparin. Risk of bias was high for most studies. In-hospital mortality, major bleeding events and pump-related thrombosis were less frequent in DTI group as compared to heparin [mortality-OR 0.69, 95% CI 0.54-0.86; major bleeding-OR 0.48, 95% CI 0.29-0.81; pump thrombosis-OR 0.55, 95% CI 0.40-0.76]. Additionally, percentage of time within therapeutic range was higher for DTI [SMD 0.54, 95% CI 0.14-0.94]. GRADE approach revealed a very low level of certainty for each outcome. CONCLUSION In this meta-analysis, DTI and especially bivalirudin showed beneficial effects on clinical outcomes in ECMO patients as compared to heparin. However, due to the lack of randomized trials, certainty of evidence is low. TRIAL REGISTRATION This systematic review and meta-analysis was prospectively registered at PROSPERO data base (reference number CRD42021237252 ).

Abstract
Background: The number of patients waiting for heart transplantation (HTX) is increasing. Optimizing the use of all available donor hearts is crucial. While mortality seems not to be affected by donor cardiopulmonary resuscitation (CPR), the impact of donor CPR on days alive and out of hospital (DAOH) is unclear. Methods: This retrospective study included adults who underwent HTX at the University Hospital Duesseldorf, Germany from 2010–2020. Main exposure was donor-CPR. Secondary exposure was the length of CPR. The primary endpoint was DAOH at one year. Results: A total of 187 patients were screened and 171 patients remained for statistical analysis. One-year mortality was 18.7%. The median DAOH at one year was 295 days (interquartile range 206–322 days). Forty-two patients (24.6%) received donor-CPR hearts. The median length of CPR was 15 (9–21) minutes. There was no significant difference in DAOH between patients with donor-CPR hearts versus patients with no-CPR hearts (CPR: 291 days (211–318 days) vs. no-CPR: 295 days (215–324 days); p = 0.619). Multivariate linear regression revealed that there was no association between length of CPR and DAOH (unstandardized coefficients B: −0.06, standard error: 0.81, 95% CI −1.65–1.53, p = 0.943). Conclusions: Donor CPR status and length of CPR are not associated with reduced DAOH at one year after HTX.

Abstract
This report describes the usefulness of the BAC genome array-CGH platform in the detection of cryptic rearrangements. We examined ten patients with normal and/or abnormal karyotypes and dysmorphic features, associated with mental retardation, autism and/or epilepsy. This approach led us to discover further cryptic chromosomal rearrangements, not previously detected by conventional cytogenetic procedures, and allowed us to better delineate genotype/phenotype correlation. Our experience shows the validity of the BAC platform as a reliable method for genome-wide screening of chromosomal aberrations in patient with idiopathic mental retardation and/or in association with autism and epilepsy.

Abstract
AIM The aim of the present work was to determine the human leukocyte (HLA) haplotype in 64 Sardinian patients affected with celiac disease, using a rapid and easy to apply sampling method that permits samples from blood drawing to be stored more easily. Numerous studies have demonstrated how the HLA system plays a very important role in immune system regulation, determining a link between this gene and a high number of pathologies including celiac disease. In fact a genetic susceptibility exists in celiac sprue, linked to HLA-DQB1*0201 and -DQB1*0302 genes which represent sierologic groups -DQ2 and -DQ8 whose early identification could be fundamental in obtaining a diagnosis of celiac disease. METHODS To realize this study a collecting method of samples was developed through the brushing of oral mucosa, which is extremely less traumatic than the classic sampling method using blood drawing, and which also allows a long conservation period before sample analysis. Samples were later analyzed with Van Embden's DNA extraction method to extract the patient's DNA, on which we executed the Polymerase Chain Reaction (PCR). To obtain the HLA haplotype from each patient we used 8 specific primers that amplified the HLA-DQB1 allele in low-resolution. RESULTS Out of the 64 patients we found 26 HLA-DQB1*02 homozygotes, 28 HLA-DQB1*02 heterozygotes and 10 negative samples for the HLA-DQB1*02 allele, thus confirming what had emerged from previous blood draws. CONCLUSION These results show how the method we developed using oral brushing is a sure method to obtain samples for determining the HLA haplotype in extra-hospital areas. This could allow the use of this method to obtain early diagnosis for chronic pathologies linked to the HLA groups and for recognizing this genotype in extensive population studies.

Abstract
We report a Sardinian family in which three members showed a mental-retardation-microcephaly-multiple malformations syndrome resulting from an unbalanced translocation (7;13)(q36;q32) which led to subtelomeric trisomy 7q36qter and partial monosomy 13q32qter. The unbalanced translocation was transmitted by alternate segregation from a female and a male carriers of the balanced translocation. The three patients had severe mental retardation, microcephaly and multiple minor facial and fingers anomalies. Neuroimages showed brain atrophy, associated in two patients with partial agenesis of the corpus callosum. FISH with chromosome 13 and 7 specific painting probes and subtelomere specific probes was instrumental for defining and characterizing the chromosomal translocation. Extensive genetic counseling and prenatal diagnosis has been offered to all the members of the family.

Abstract
We report a case of partial proximal trisomy of the long arm of chromosome 10 confirmed by fluorescence in situ hibridization (FISH) performed with whole chromosome 10 specific painting and specific yac clones. The phenotypic findings, compared to those found in other published cases with the same karyotype, support the recognition of a distinctive partial proximal trisomy 10q syndrome (10q11-->q22).

Abstract
Two brothers are reported who share mental retardation, conjunctival teleangectasias (mainly equatorial) and characteristic flat face with small mouth and thin prolabia. At the neuropsychological examination, the older brother at 14 years showed a full scale IQ of 40 (WISC), with verbal IQ 45 and performance IQ 44. The younger brother at 7 years showed a full scale IQ of 58 (WPPSI), with verbal IQ 67 and performance IQ 55. Chromosome studies showed a duplication Xp22-Xpter in both brothers and in the inactivated X of their mother. The anomaly was not present in a 3rd healthy brother and in other healthy relatives. The mother has normal intelligence and did not present any of the physical features of her affected sons.

Abstract
We report the results of a two-year non randomized prednisolone trial carried out in 18 thalassemia major patients with chronic active hepatitis and in 16 controls. We found a beneficial effect on the biochemical remission rate and on the extent of liver inflammation with no significant side effects and no overt reactivation of possible latent HBV infection at three-year follow-up. However, a more prolonged longitudinal study is necessary in order to evaluate whether steroid treatment can impede the evolution to cirrhosis without determining long-term consequences, depending on virus-host interactions such as liver cell carcinoma.

Abstract
In this study maximum urinary iron elimination with continuous desferrioxamine subcutaneous infusion was obtained in thalassemia major patients with chronic persistent or active hepatitis with lower doses (60 mg/kg) than those necessary in patients without hepatitis (80 mg/kg). Since dose-response curves were highly variable the treatment schedule should be tailored to the individual needs of each patient. Both groups may achieve iron balance but chronic hepatitis patients have more frequently a net urinary iron excretion. In patients with chronic hepatitis no correlation was found between serum ferritin levels or serum ferritin/aspartate aminotransferase ratios and transfusional iron overload while serum ferritin/aspartate aminotransferase ratios were seen to be correlated with liver iron stores.

Abstract
This study on serum ferritin levels in urinary iron excretion after 12h subcutaneous infusion of desferrioxamine in 10 thalassemia intermedia patients shows that even nontransfusion-dependent patients may have positive iron balance resulting in iron overload from 5 years of age. However, the iron overload found in these patients appears to be much lower than in age matched patients with transfusion-dependent thalassemia major. Iron overload increases with advancing age, as shown by increasing serum ferritin levels and desferrioxamine-induced urinary iron elimination. After a six month trial of 12h continuous subcutaneous desferrioxamine administration there was a significant decline in serum ferritin levels. From this study it seems that iron chelation is indicated in thalassemia intermedia patients over 5 years of age in order to prevent iron accumulation. However, the appropriate treatment schedule should be tailored to the individual needs of each patients, established by close monitoring of serum ferritin levels and desferrioxamine-induced urinary iron elimination.
