  • Post cholecystectomy bile duct injury : early, intermediate or late repair with hepaticojejunostomy - an E-AHPBA multi-center study
  • 2019

    • Background: Treatment of bile duct injuries (BDI) during cholecystectomy depends on the severity of injury and the timing of diagnosis. Standard of care for severe BDIs is hepaticojejunostomy. The aim of this retrospective multi-center study was to assess the optimal timing for repair of BDI with hepaticojejunostomy.Methods: Members of the European-African HepatoPancreatoBiliary Association were invited to report all consecutive patients with hepaticojejunostomy after BDI from January 2000 to June 2016. Patients were stratified according to the timing of biliary reconstruction with hepaticojejunostomy: early (day 0-7), intermediate (1-6 weeks) and late (6 weeks-6 months). Primary endpoint was re-intervention >90 days after the hepaticojejunostomy and secondary endpoints were severe 90-day complications and liver-related mortality.Results: In total 913 patients from 48 centers were included in the analysis. In 401 patients (44%) the bile duct injury was diagnosed intraoperatively, and 126 patients (14%) suffered from concomitant vascular injury. In multivariable analysis the timing of hepaticojejunostomy had no impact on postoperative complications, the need for re-intervention after 90 days nor liver-related mortality. The rate of re-intervention more than 90 days after the hepaticojejunostomy was significantly increased in male patients but decreased in older patients. Severe co-morbidity increased the risk for liver-related mortality (HR 3.439; CI 1.37-8.65; p = 0.009).Conclusion: After BDI occurring during cholecystectomy, the timing of biliary reconstruction with hepaticojejunostomy did not have any impact on severe postoperative complications, the need for re-intervention or liver-related mortality. Individualised treatment after iatrogenic bile duct injury is still advisable.

  • Molecular Profiling for Predictors of Radiosensitivity in Patients with Breast or Head-and-Neck Cancer
  • 2020
  • Ingår i: Cancers. - : MDPI AG. - 2072-6694. ; 12:3

    • Nearly half of all cancers are treated with radiotherapy alone or in combination with other treatments, where damage to normal tissues is a limiting factor for the treatment. Radiotherapy-induced adverse health effects, mostly of importance for cancer patients with long-term survival, may appear during or long time after finishing radiotherapy and depending on the patient's radiosensitivity. Currently, there is no assay available that can reliably predict the individual's response to radiotherapy. We profiled two study sets from breast (n = 29) and head-and-neck cancer patients (n = 74) that included radiosensitive patients and matched radioresistant controls. We studied 55 single nucleotide polymorphisms (SNPs) in 33 genes by DNA genotyping and 130 circulating proteins by affinity-based plasma proteomics. In both study sets, we discovered several plasma proteins with the predictive power to find radiosensitive patients (adjusted p < 0.05) and validated the two most predictive proteins (THPO and STIM1) by sandwich immunoassays. By integrating genotypic and proteomic data into an analysis model, it was found that the proteins CHIT1, PDGFB, PNKD, RP2, SERPINC1, SLC4A, STIM1, and THPO, as well as the VEGFA gene variant rs69947, predicted radiosensitivity of our breast cancer (AUC = 0.76) and head-and-neck cancer (AUC = 0.89) patients. In conclusion, circulating proteins and a SNP variant of VEGFA suggest that processes such as vascular growth capacity, immune response, DNA repair and oxidative stress/hypoxia may be involved in an individual's risk of experiencing radiation-induced toxicity.

  • Recommendations for participation in competitive and leisure time sport in athletes with cardiomyopathies, myocarditis, and pericarditis: position statement of the Sport Cardiology Section of the European Association of Preventive Cardiology (EAPC)
  • 2019
  • Ingår i: European Heart Journal. - 0195-668X .- 1522-9645. ; 40:1, s. 19-33
  • Tidskriftsartikel (refereegranskat)abstract
    • Myocardial diseases are associated with an increased risk of potentially fatal cardiac arrhythmias and sudden cardiac death/cardiac arrest during exercise, including hypertrophic cardiomyopathy, dilated cardiomyopathy, left ventricular non-compaction, arrhythmogenic cardiomyopathy, and myo-pericarditis. Practicing cardiologists and sport physicians are required to identify high-risk individuals harbouring these cardiac diseases in a timely fashion in the setting of preparticipation screening or medical consultation and provide appropriate advice regarding the participation in competitive sport activities and/or regular exercise programmes. Many asymptomatic (or mildly symptomatic) patients with cardiomyopathies aspire to participate in leisure-time and amateur sport activities to take advantage of the multiple benefits of a physically active lifestyle. In 2005, The European Society of Cardiology (ESC) published recommendations for participation in competitive sport in athletes with cardiomyopathies and myo-pericarditis. One decade on, these recommendations are partly obsolete given the evolving knowledge of the diagnosis, management and treatment of cardiomyopathies and myo-pericarditis. The present document, therefore, aims to offer a comprehensive overview of the most updated recommendations for practicing cardiologists and sport physicians managing athletes with cardiomyopathies and myo-pericarditis and provides pragmatic advice for safe participation in competitive sport at professional and amateur level, as well as in a variety of recreational physical activities.

  • Influence of genetic background and oxidative stress response on risk of mandibular osteoradionecrosis after radiotherapy of head and neck cancer
  • 2016
  • Ingår i: Head and Neck. - 1043-3074 .- 1097-0347. ; 38:3, s. 387-393
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Osteoradionecrosis (ORN) of the mandible is a severe complication of head and neck radiotherapy (RT) treatment, where the impact of individual radiosensitivity has been a suggested explanation. Methods: A cohort of patients with stage II/III ORN was compared to matched controls. Blood was collected and irradiated in vitro to study the capacity to handle radiation-induced oxidative stress. Patients were also genotyped for 8 single-nucleotide polymorphisms (SNPs) in genes involved in the oxidative stress response. Results: A difference in 8-oxo-7,8-dihydro-2-deoxyguanosine (8-oxo-dG) levels was found between the patient cohorts (p = 0.01). The SNP rs1695 in glutathione s-transferase p1 (GSTP1) was also found to be more frequent in the patients with ORN (p = .02). Multivariate analysis of the clinical and biological factors revealed concomitant brachytherapy plus the 2 biomarkers to be significant factors which influense risk of mandibular osteoradionecrosis after radiotherapy of head and neck cancer. Conclusion: The current study indicates that oxidative stress response contributes to individual radiosensitivity and healthy tissue damage caused by RT and may be predicted by biomarker analysis.
