  • A comparison of very old patients admitted to intensive care unit after acute versus elective surgery or intervention
  • 2019
  • Ingår i: Journal of critical care. - : W B SAUNDERS CO-ELSEVIER INC. - 0883-9441 .- 1557-8615. ; 52, s. 141-148
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: We aimed to evaluate differences in outcome between patients admitted to intensive care unit (ICU) after elective versus acute surgery in a multinational cohort of very old patients (80 years; VIP). Predictors of mortality, with special emphasis on frailty, were assessed.Methods: In total, 5063 VIPs were induded in this analysis, 922 were admitted after elective surgery or intervention, 4141 acutely, with 402 after acute surgery. Differences were calculated using Mann-Whitney-U test and Wilcoxon test. Univariate and multivariable logistic regression were used to assess associations with mortality.Results: Compared patients admitted after acute surgery, patients admitted after elective surgery suffered less often from frailty as defined as CFS (28% vs 46%; p < 0.001), evidenced lower SOFA scores (4 +/- 5 vs 7 +/- 7; p < 0.001). Presence of frailty (CFS >4) was associated with significantly increased mortality both in elective surgery patients (7% vs 12%; p = 0.01), in acute surgery (7% vs 12%; p = 0.02).Conclusions: VIPs admitted to ICU after elective surgery evidenced favorable outcome over patients after acute surgery even after correction for relevant confounders. Frailty might be used to guide clinicians in risk stratification in both patients admitted after elective and acute surgery.

  • Temozolomide in Advanced Neuroendocrine Neoplasms : Pharmacological and Clinical Aspects
  • 2015
  • Ingår i: Neuroendocrinology. - : S. Karger AG. - 0028-3835 .- 1423-0194. ; 101:4, s. 274-288
  • Tidskriftsartikel (refereegranskat)abstract
    • Alkylating agents, such as streptozocin and dacarbazine, have been reported as active in neuroendocrine neoplasms (NENs). Temozolomide (TMZ) is an oral, potentially less toxic derivative of dacarbazine, which has shown activity both as a single agent and in combination with other drugs. Nevertheless, its role in NENs has not been well defined. Several retrospective and prospective phase I-II studies have been published describing its use in a variety of NENs. In a retrospective series, the combination of capecitabine and TMZ was reported to be associated with a particularly high tumour response in pancreatic NENs as a first-line treatment. Although in NENs, determination of the CP-nnethylguanineDNA methyltransferase (MGMT) status has been suggested as a predictive biomarker of response, its role still remains investigational, awaiting validation along with the establishment of the optimal detection method. Metronomic schedules have been reported to potentially overcome MGMT-related drug resistance. Toxicity is manageable if well monitored. We reviewed the literature regarding pharmacological and clinical aspects of TMZ, focusing on specific settings of NENs, different schedules, toxicity and safety profiles, and potential predictive biomarkers of response.

  • Newborn screening in metachromatic leukodystrophy – European consensus-based recommendations on clinical management
  • 2024
  • Ingår i: European Journal of Paediatric Neurology. - 1090-3798. ; 49, s. 141-154
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Metachromatic leukodystrophy (MLD) is a rare autosomal recessive lysosomal storage disorder resulting from arylsulfatase A enzyme deficiency, leading to toxic sulfatide accumulation. As a result affected individuals exhibit progressive neurodegeneration. Treatments such as hematopoietic stem cell transplantation (HSCT) and gene therapy are effective when administered pre-symptomatically. Newborn screening (NBS) for MLD has recently been shown to be technically feasible and is indicated because of available treatment options. However, there is a lack of guidance on how to monitor and manage identified cases. This study aims to establish consensus among international experts in MLD and patient advocates on clinical management for NBS-identified MLD cases. Methods: A real-time Delphi procedure using eDELPHI software with 22 experts in MLD was performed. Questions, based on a literature review and workshops, were answered during a seven-week period. Three levels of consensus were defined: A) 100%, B) 75–99%, and C) 50–74% or >75% but >25% neutral votes. Recommendations were categorized by agreement level, from strongly recommended to suggested. Patient advocates participated in discussions and were involved in the final consensus. Results: The study presents 57 statements guiding clinical management of NBS-identified MLD patients. Key recommendations include timely communication by MLD experts with identified families, treating early-onset MLD with gene therapy and late-onset MLD with HSCT, as well as pre-treatment monitoring schemes. Specific knowledge gaps were identified, urging prioritized research for future evidence-based guidelines. Discussion: Consensus-based recommendations for NBS in MLD will enhance harmonized management and facilitate integration in national screening programs. Structured data collection and monitoring of screening programs are crucial for evidence generation and future guideline development. Involving patient representatives in the development of recommendations seems essential for NBS programs.

  • Transthoracic impedance variability to assess quality of chest compression in out-of-hospital cardiac arrest
  • Ingår i: Acta Anaesthesiologica Scandinavica. - 0001-5172.
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Chest compression is a lifesaving intervention in out-of-hospital cardiac arrest (OHCA), but the optimal metrics to assess its quality have yet to be identified. The objective of this study was to investigate whether a new parameter, that is, the variability of the chest compression-generated transthoracic impedance (TTI), namely ImpCC, which measures the consistency of the chest compression maneuver, relates to resuscitation outcome. Methods: This multicenter observational, retrospective study included OHCAs with shockable rhythm. ImpCC variability was evaluated with the power spectral density analysis of the TTI. Multivariate regression model was used to examine the impact of ImpCC variability on defibrillation success. Secondary outcome measures were return of spontaneous circulation and survival. Results: Among 835 treated OHCAs, 680 met inclusion criteria and 565 matched long-term outcomes. ImpCC was significantly higher in patients with unsuccessful defibrillation compared to those with successful defibrillation (p =.0002). Lower ImpCC variability was associated with successful defibrillation with an odds ratio (OR) of 0.993 (95% confidence interval [95% CI], 0.989–0.998, p =.003), while the standard chest compression fraction (CCF) was not associated (OR 1.008 [95 % CI, 0.992–1.026, p =.33]). Neither ImpCC nor CCF was associated with long-term outcomes. Conclusions: In this population, consistency of chest compression maneuver, measured by variability in TTI, was an independent predictor of defibrillation outcome. ImpCC may be a useful novel metrics for improving quality of care in OHCA.

  • Propranolol Reduces the Development of Lesions and Rescues Barrier Function in Cerebral Cavernous Malformations : A Preclinical Study
  • 2021
  • Ingår i: Stroke. - : Lippincott Williams & Wilkins. - 0039-2499 .- 1524-4628. ; 52:4, s. 1418-1427
  • Tidskriftsartikel (refereegranskat)abstract
    • Background and Purpose: Cerebral cavernous malformations (CCM) present as mulberry-like malformations of the microvasculature of the central nervous system. Current medical treatment of CCM lesions is limited to surgical removal of the vascular malformations. It is, therefore, important to identify therapeutic drug treatments for patients with CCM. Propranolol has shown great benefit in the treatment of infantile hemangioma. In addition, patients with CCM who receive propranolol have demonstrated a reduction of their lesions. Our investigation set out to provide preclinical data to support propranolol as a therapeutic treatment.Methods: An inducible endothelial-specific Ccm3 knockout murine model (CCM3(iECKO)) was used, with assessment of lesion quantity and size following oral treatment with propranolol. Scanning and transmission electron microscopy were used to characterize the CCM3(iECKO) lesions and the effects of propranolol on the disease. Immunofluorescent imaging was used to investigate pericyte coverage in the propranolol-treated CCM3(iECKO) mice.Results: With propranolol treatment, the lesion quantity, size, and volume decreased in both the brain and retina in the CCM3(iECKO) model. Novel characteristics of the CCM3(iECKO) lesions were discovered using electron microscopy, including plasmalemmal pits and thickening of the endothelial-pericyte basal membrane. These characteristics were absent with propranolol treatment. Pericyte coverage of the CCM3(iECKO) lesions increased after propranolol treatment, and vascular leakage was reduced.Conclusions: This study supports the concept that propranolol can be used to reduce and stabilize vascular lesions and can, therefore, be suggested as a pharmaceutical treatment for CCM.

  • Inventory of current practices regarding hematopoietic stem cell transplantation in metachromatic leukodystrophy in Europe and neighboring countries
  • 2024
  • Ingår i: Orphanet Journal of Rare Diseases. - 1750-1172. ; 19:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: For decades, early allogeneic stem cell transplantation (HSCT) has been used to slow neurological decline in metachromatic leukodystrophy (MLD). There is lack of consensus regarding who may benefit, and guidelines are lacking. Clinical practice relies on limited literature and expert opinions. The European Reference Network for Rare Neurological Diseases (ERN-RND) and the MLD initiative facilitate expert panels for treatment advice, but some countries are underrepresented. This study explores organizational and clinical HSCT practices for MLD in Europe and neighboring countries to enhance optimization and harmonization of cross-border MLD care. Methods: A web-based EUSurvey was distributed through the ERN-RND and the European Society for Blood and Marrow Transplantation Inborn Errors Working Party. Personal invitations were sent to 89 physicians (43 countries) with neurological/metabolic/hematological expertise. The results were analyzed and visualized using Microsoft Excel and IBM SPSS statistics. Results: Of the 30 countries represented by 42 respondents, 23 countries offer HSCT for MLD. The treatment is usually available in 1–3 centers per country (18/23, 78%). Most countries have no or very few MLD patients transplanted during the past 1–5 years. The eligibility criteria regarding MLD subtype, motor function, IQ, and MRI largely differ across countries. Conclusion: HSCT for MLD is available in most European countries, but uncertainties exist in Eastern and South-Eastern Europe. Applied eligibility criteria and management vary and may not align with the latest scientific insights, indicating physicians’ struggle in providing evidence-based care. Interaction between local physicians and international experts is crucial for adequate treatment decision-making and cross-border care in the rapidly changing MLD field.
