  • The Magnitude of Global Marine Species Diversity
  • 2012
  • Ingår i: Current Biology. - : Elsevier BV. - 0960-9822 .- 1879-0445. ; 22:23, s. 2189-2202

    • Background: The question of how many marine species exist is important because it provides a metric for how much we do and do not know about life in the oceans. We have compiled the first register of the marine species of the world and used this baseline to estimate how many more species, partitioned among all major eukaryotic groups, may be discovered. Results: There are similar to 226,000 eukaryotic marine species described. More species were described in the past decade (similar to 20,000) than in any previous one. The number of authors describing new species has been increasing at a faster rate than the number of new species described in the past six decades. We report that there are similar to 170,000 synonyms, that 58,000-72,000 species are collected but not yet described, and that 482,000-741,000 more species have yet to be sampled. Molecular methods may add tens of thousands of cryptic species. Thus, there may be 0.7-1.0 million marine species. Past rates of description of new species indicate there may be 0.5 +/- 0.2 million marine species. On average 37% (median 31%) of species in over 100 recent field studies around the world might be new to science. Conclusions: Currently, between one-third and two-thirds of marine species may be undescribed, and previous estimates of there being well over one million marine species appear highly unlikely. More species than ever before are being described annually by an increasing number of authors. If the current trend continues, most species will be discovered this century.

  • Effects of controlled-release metoprolol on total mortality, hospitalizations, and well-being in patients with heart failure. The Metoprolol CR/XL randomized intervention trial in congestive heart failure
  • 2000
  • Ingår i: Journal of the American Medical Association. - : JAMA. - 0221-7678. ; 283:10, s. 1295-1302
  • Tidskriftsartikel (refereegranskat)abstract
    • Results from recent studies on the effects of beta1-blockade in patients with heart failure demonstrated a 34% reduction in total mortality. However, the effect of beta1-blockade on the frequency of hospitalizations, symptoms, and quality of life in patients with heart failure has not been fully explored. OBJECTIVE: To examine the effects of the beta1-blocker controlled-release/extended-release metoprolol succinate (metoprolol CR/XL) on mortality, hospitalization, symptoms, and quality of life in patients with heart failure. DESIGN: Randomized, double-blind controlled trial, preceded by a 2-week single-blind placebo run-in period, conducted from February 14, 1997, to October 31, 1998, with a mean follow-up of 1 year. SETTING: Three hundred thirteen sites in 14 countries. PARTICIPANTS: Patients (n = 3991) with chronic heart failure, New York Heart Association (NYHA) functional class II to IV, and ejection fraction of 0.40 or less who were stabilized with optimum standard therapy. INTERVENTIONS: Patients were randomized to metoprolol CR/XL, 25 mg once per day (NYHA class II), or 12.5 mg once per day (NYHA class III or IV), titrated for 6 to 8 weeks up to a target dosage of 200 mg once per day (n = 1990); or matching placebo (n = 2001). MAIN OUTCOME MEASURES: Total mortality or any hospitalization (time to first event), number of hospitalizations for worsening heart failure, and change in NYHA class, by intervention group; quality of life was assessed in a substudy of 741 patients. RESULTS: The incidence of all predefined end points was lower in the metoprolol CR/XL group than in the placebo group, including total mortality or all-cause hospitalizations (the prespecified second primary end point; 641 vs 767 events; risk reduction, 19%; 95% confidence interval [CI], 10%-27%; P<.001); total mortality or hospitalizations due to worsening heart failure (311 vs 439 events; risk reduction, 31%; 95% CI, 20%-40%; P<.001), number of hospitalizations due to worsening heart failure (317 vs 451; P<.001); and number of days in hospital due to worsening heart failure (3401 vs 5303 days; P<.001). NYHA functional class, assessed by physicians, and McMaster Overall Treatment Evaluation score, assessed by patients, both improved in the metoprolol CR/XL group compared with the placebo group (P = .003 and P = .009, respectively). CONCLUSIONS: In this study of patients with symptomatic heartfailure, metoprolol CR/XL improved survival, reduced the need for hospitalizations due to worsening heart failure, improved NYHA functional class, and had beneficial effects on patient well-being.

  • The solute carrier SLC7A1 may act as a protein transporter at the blood-brain barrier
  • 2024
  • Ingår i: European Journal of Cell Biology. - : Elsevier. - 0171-9335 .- 1618-1298. ; 103:2
  • Tidskriftsartikel (refereegranskat)abstract
    • Despite extensive research, targeted delivery of substances to the brain still poses a great challenge due to the selectivity of the blood -brain barrier (BBB). Most molecules require either carrier- or receptor -mediated transport systems to reach the central nervous system (CNS). These transport systems form attractive routes for the delivery of therapeutics into the CNS, yet the number of known brain endothelium -enriched receptors allowing the transport of large molecules into the brain is scarce. Therefore, to identify novel BBB targets, we combined transcriptomic analysis of human and murine brain endothelium and performed a complex screening of BBBenriched genes according to established selection criteria. As a result, we propose the high -affinity cationic amino acid transporter 1 (SLC7A1) as a novel candidate for transport of large molecules across the BBB. Using RNA sequencing and in situ hybridization assays, we demonstrated elevated SLC7A1 gene expression in both human and mouse brain endothelium. Moreover, we confirmed SLC7A1 protein expression in brain vasculature of both young and aged mice. To assess the potential of SLC7A1 as a transporter for larger proteins, we performed internalization and transcytosis studies using a radiolabelled or fluorophore-labelled anti-SLC7A1 antibody. Our results showed that SLC7A1 internalised a SLC7A1-specific antibody in human colorectal carcinoma (HCT116) cells. Moreover, transcytosis studies in both immortalised human brain endothelial (hCMEC/D3) cells and primary mouse brain endothelial cells clearly demonstrated that SLC7A1 effectively transported the SLC7A1specific antibody from luminal to abluminal side. Therefore, here in this study, we present for the first time the SLC7A1 as a novel candidate for transport of larger molecules across the BBB.

  • Scapula fractures: Interobserver reliability of classification and treatment
  • 2014
  • Ingår i: Journal of Orthopaedic Trauma. - : Lippincott, Williams andamp; Wilkins. - 0890-5339 .- 1531-2291. ; 28:3, s. 124-129
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: There is substantial variation in the classification and management of scapula fractures. The first purpose of this study was to analyze the interobserver reliability of the OTA/AO classification and the New International Classification for Scapula Fractures. The second purpose was to assess the proportion of agreement among orthopaedic surgeons on operative or nonoperative treatment. Design: Web-based reliability study. Setting: Independent orthopaedic surgeons from several countries were invited to classify scapular fractures in an online survey. Participants: One hundred three orthopaedic surgeons evaluated 35 movies of three-dimensional computerized tomography reconstruction of selected scapular fractures, representing a full spectrum of fracture patterns. Main Outcome Measurements: Fleiss kappa (κ) was used to assess the reliability of agreement between the surgeons. Results: The overall agreement on the OTA/AO classification was moderate for the types (A, B, and C, κ = 0.54) with a 71% proportion of rater agreement (PA) and for the 9 groups (A1 to C3, κ = 0.47) with a 57% PA. For the New International Classification, the agreement about the intraarticular extension of the fracture (Fossa (F), κ = 0.79) was substantial and the agreement about a fractured body (Body (B), κ = 0.57) or process was moderate (Process (P), κ = 0.53); however, PAs were more than 81%. The agreement on the treatment recommendation was moderate (κ = 0.57) with a 73% PA. Conclusions: The New International Classification was more reliable. Body and process fractures generated more disagreement than intraarticular fractures and need further clear definitions. Copyright © 2013 by Lippincott Williams and Wilkins.

  • Early enteral supply of fiber and Lactobacilli versus conventional nutrition: A controlled trial in patients with major abdominal surgery
  • 2002
  • Ingår i: Nutrition. - 1873-1244. ; 18:7-8, s. 609-615
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: Early enteral nutrition with fiber-containing solutions plus Lactobacillus may reduce bacterial translocation and minimize the incidence of infections after surgery. METHODS: In a prospective, randomized trial in three groups (n = 30/group) of patients after major abdominal surgery, we compared our previous regimen with parenteral nutrition or fiber-free enteral nutrition (group A) with enteral fiber-containing nutrition with living Lactobacillus (group B) and heat-killed Lactobacillus (group C). The main endpoint was the development of bacterial infection. Other analyzed parameters were the durations of antibiotic therapy and hospital stay. non-infectious complications. side effects of the nutrition, and onset of bowel movement. Routine parameters, nutritional parameters, and cellular immune status in the blood were measured preoperatively and on 1, 5, and 10 d postoperatively. RESULTS: The incidence of infections was significantly lower (P = 0.01) in groups B and C with enteral nutrition containing fibers (10% each) than in group A (30%). Patients in group B received antibiotics for a significantly shorter time (P = 0.04) than did the patients in groups A and C. The length of hospital stay and the incidence of non-infectious complications did not differ significantly. Fibers and lactobacilli were well tolerated. There were no general benefits of living Lactobacillus as opposed to heat-killed Lactobacillus in the entire study population, but benefits were observed in the patients with gastric and pancreas resections, although no statistical analysis was done due to their small numbers. CONCLUSIONS: Early enteral nutrition with fiber-containing solutions reduced the rate of postoperative infections in comparison with parenteral nutrition and fiber-free enteral formula. Addition of living Lactobacillus seemed to increase the benefits in patients with gastric and pancreatic resections.

  • Early enteral supply of lactobacillus and fiber versus selective bowel decontamination: A controlled trial in liver transplant recipients
  • 2002
  • Ingår i: Transplantation. - 1534-6080. ; 74:1, s. 123-128
  • Tidskriftsartikel (refereegranskat)abstract
    • Background. Early enteral nutrition with solutions containing prebiotics (fiber) and probiotics (Lactobacillus) is suggested to reduce bacterial translocation and minimize the incidence of infections after liver transplantation. Methods. In a prospective, randomized placebo-controlled trial consisting of 95 patients, we compared the incidence of postoperative infections and other complications after liver transplantation among three different groups, all supplied with early enteral nutrition: (a) standard formula plus selective bowel decontamination (SBD), (b) fiber-containing formula plus living Lactobacillus plantarum 299, and (c) fiber-containing formula plus heat-killed L plantarum 299. Results. The groups were comparable regarding preoperative American Society of Anesthesiologists classification, Child-Pugh classification of cirrhosis, operative data, and degree of immunosuppression. The patients who received living lactobacilli plus fiber developed significantly fewer bacterial infections (1370) than the patients with SBD (48%). The incidence of infections was 34% in the group with inactivated lactobacilli and fiber. Cholangitis and pneumonia were the leading infections and enterococci the most commonly isolated bacteria. In the living Lactobacillus group, the mean duration of antibiotic therapy, the mean total hospital stay, and the stay on the intensive care unit were also shorter than in the groups with inactivated lactobacilli and fiber as well as with SBD. However, these differences did not reach statistical significance. Conclusions. Early enteral nutrition with fiber-containing solutions and living L plantarum 299 was well tolerated. It decreases markedly the rate of postoperative infections both in comparison with inactivated L plantarum 299 and significantly with SBD and a standard enteral nutrition formula. As it is a cheap and feasible alternative to SBD, further studies should evaluate whether this ecoimmunonutrition should be already started while patients are on the waiting list for transplantation.

  • Einfluss von Probiotika und Ballaststoffen auf die Inzidenz bakterieller Infektionen nach viszeralchirurgischen Eingriffen - Ergebnisse einer prospektiven Studie
  • 2002
  • Ingår i: Zeitschrift für Gastroenterologie. - : Georg Thieme Verlag KG. - 0044-2771 .- 1439-7803. ; 40:10, s. 869-876
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Early enteral nutrition with fibre and probiotics has been effective in preventing bacterial translocation and is therefore expected to reduce the incidence of postoperative bacterial infections. Patients and methods: In a prospective randomized trial including 172 patients following major abdominal surgery or liver transplantation, the incidence of bacterial infections was compared in patients receiving either a) conventional parenteral or enteral nutrition, b) enteral nutrition with fibre and lactobacillus plantarum 299 or c) enteral nutrition with fibre and heat inactivated lactobacilli (placebo). Liver transplant recipients were also treated with selective bowel decontamination (SBD). Routine laboratory parameters, nutritional parameters and the cellular immune status were measured preoperatively and on postoperative days 1, 5 and 10. Results: Patients were comparable regarding preoperative ASA-classification, Child-Pugh classification of cirrhosis, operative data and immunosuppression. The incidence of bacterial infections after liver, gastric oder pancreas resection was 31% in the conventional group a) compared to 4% in the lactobacillus-group b) and 13% in the placebo-group c). In the analysis of 95 liver transplant recipients, 13% group b)-patients developed infections compared to 48% group a)-patients and 34% group c)-patients. The difference between groups a) and b) was statistically significant in both cases. In addition, the duration of antibiotic therapy was significantly shorter in the lactobacillus-group. Cholangitis and pneumonia were the most frequent infections and enterococci the most frequently isolated bacteria. Fibre and lactobacilli were well tolerated in most cases. Conclusion: Fibre and probiotics could lower the incidence of bacterial infections following major abdominal surgery in comparison to conventional nutrition with or without SBD. With this new concept, costs can be reduced by shortening the duration of antibiotic therapy and sparing SBD.

  • A prospective randomised, open-labeled, trial comparing sirolimus-containing versus mTOR-inhibitor-free immunosuppression in patients undergoing liver transplantation for hepatocellular carcinoma.
  • 2010
  • Ingår i: BMC cancer. - : Springer Science and Business Media LLC. - 1471-2407. ; 10
  • Tidskriftsartikel (refereegranskat)abstract
    • The potential anti-cancer effects of mammalian target of rapamycin (mTOR) inhibitors are being intensively studied. To date, however, few randomised clinical trials (RCT) have been performed to demonstrate anti-neoplastic effects in the pure oncology setting, and at present, no oncology endpoint-directed RCT has been reported in the high-malignancy risk population of immunosuppressed transplant recipients. Interestingly, since mTOR inhibitors have both immunosuppressive and anti-cancer effects, they have the potential to simultaneously protect against immunologic graft loss and tumour development. Therefore, we designed a prospective RCT to determine if the mTOR inhibitor sirolimus can improve hepatocellular carcinoma (HCC)-free patient survival in liver transplant (LT) recipients with a pre-transplant diagnosis of HCC.

  • mTOR Inhibition Is Most Beneficial After Liver Transplantation for Hepatocellular Carcinoma in Patients With Active Tumors
  • 2020
  • Ingår i: Annals of Surgery. - : LIPPINCOTT WILLIAMS & WILKINS. - 0003-4932 .- 1528-1140. ; 272:5, s. 855-862
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: The aim of this study was to evaluate the survival benefit of sirolimus in patients undergoing liver transplantation (LT) for hepatocellular carcinoma (HCC) (exploratory analysis of the SiLVER-trial). Summary and Background Data: Patients receiving LT) for HCC are at a high risk for tumor recurrence. Calcineurin inhibitors have shown evidence to promote cancer growth, whereas mammalian target of rapamycin (mTOR) inhibitors like sirolimus have anticancer effects. In the SiLVER-trial (Clinicaltrials.gov:NCT00355862), the effect of sirolimus on the recurrence of HCC after LTwas investigated in a prospective randomized trial. Although the primary endpoint of improved disease-free survival (DFS) with sirolimus was not met, outcomes were improved for patients in the sirolimus-treatment arm in the first 3 to 5 years. To learn more about the key variables, a multivariate analysis was performed on the SiLVER-trial data. Patients and Methods: Data from 508 patients of the intention-to-treat analysis were included in exploratory univariate and multivariate models for overall survival (OS), DFS and a competing risk analysis for HCC recurrence. Results: Sirolimus use for >= 3 months after LT for HCC independently reduced the hazard for death in the multivariate analysis [hazard ratio (HR): 0.7 (95% confidence interval, CI: 0.52-0.96, P = 0.02). Most strikingly, patients with an alpha-fetoprotein (AFP) >= 10 ng/mL and having used sirolimus for >= 3 months, benefited most with regard to OS, DFS, and HCC-recurrence (HR: 0.49- 0.59, P = 0.0079- 0.0245). Conclusions: mTOR-inhibitor treatment with sirolimus for >= 3 months improves outcomes in LT for HCC, especially in patients with AFP-evidence of higher tumor activity, advocating particularly for mTOR inhibitor use in this subgroup of patients. Clinical Trial Registration: EudraCT: 2005-005362-36 Clinicaltrials.gov: NCT00355862.

  • Predictive performance and clinical application of COV50, a urinary proteomic biomarker in early COVID-19 infection : a prospective multicentre cohort study
  • 2022
  • Ingår i: The Lancet Digital Health. - : Elsevier. - 2589-7500. ; 4:10, s. e727-e737
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The SARS-CoV-2 pandemic is a worldwide challenge. The CRIT-CoV-U pilot study generated a urinary proteomic biomarker consisting of 50 peptides (COV50), which predicted death and disease progression from SARS-CoV-2. After the interim analysis presented for the German Government, here, we aimed to analyse the full dataset to consolidate the findings and propose potential clinical applications of this biomarker.Methods: CRIT-CoV-U was a prospective multicentre cohort study. In eight European countries (Austria, France, Germany, Greece, North Macedonia, Poland, Spain, and Sweden), 1012 adults with PCR-confirmed COVID-19 were followed up for death and progression along the 8-point WHO scale. Capillary electrophoresis coupled with mass spectrometry was used for urinary proteomic profiling. Statistical methods included logistic regression and receiver operating characteristic curve analysis with a comparison of the area under curve (AUC) between nested models. Hospitalisation costs were derived from the care facility corresponding with the Markov chain probability of reaching WHO scores ranging from 3 to 8 and flat-rate hospitalisation costs adjusted for the gross per capita domestic product of each country.Findings: From June 30 to Nov 19, 2020, 228 participants were recruited, and from April 30, 2020, to April 14, 2021, 784 participants were recruited, resulting in a total of 1012 participants. The entry WHO scores were 1–3 in 445 (44%) participants, 4–5 in 529 (52%) participants, and 6 in 38 (4%) participants; and of all participants, 119 died and 271 had disease progression. The odds ratio (OR) associated with COV50 in all 1012 participants for death was 2·44 (95% CI 2·05–2·92) unadjusted and 1·67 (1·34–2·07) when adjusted for sex, age, BMI, comorbidities, and baseline WHO score; and for disease progression, the OR was 1·79 (1·60–2·01) when unadjusted and 1·63 (1·41–1·91) when adjusted (p<0·0001 for all). The predictive accuracy of the optimised COV50 thresholds was 74·4% (71·6–77·1%) for mortality (threshold 0·47) and 67·4% (64·4–70·3%) for disease progression (threshold 0·04). When adjusted for covariables and the baseline WHO score, these thresholds improved AUCs from 0·835 to 0·853 (p=0·033) for death and from 0·697 to 0·730 (p=0·0008) for progression. Of 196 participants who received ambulatory care, 194 (99%) did not reach the 0·04 threshold. The cost reductions associated with 1 day less hospitalisation per 1000 participants were million Euro (M€) 0·887 (5–95% percentile interval 0·730–1·039) in participants at a low risk (COV50 <0·04) and M€2·098 (1·839-2·365) in participants at a high risk (COV50 ≥0·04).Interpretation: The urinary proteomic COV50 marker might be predictive of adverse COVID-19 outcomes. Even in people with mild-to-moderate PCR-confirmed infections (WHO scores 1–4), the 0·04 COV50 threshold justifies earlier drug treatment, thereby potentially reducing the number of days in hospital and associated costs.

  • Using oxygen-consuming thermoset plastics to generate hypoxic conditions in microfluidic devices for potential cell culture applications
  • 2020
  • Ingår i: 21st International Conference on Miniaturized Systems for Chemistry and Life Sciences, MicroTAS 2017. - : Chemical and Biological Microsystems Society. ; , s. 812-813
  • Konferensbidrag (refereegranskat)abstract
    • The precise control of the oxygen concentration in a cellular environment allows the study of cells under physiologically relevant conditions. This work reports on a novel method for the generation of reduced dissolved oxygen concentrations in microfluidic chambers for cell- and organ-on-chip applications. Using a thermoset polymeric material (OSTEMERTM), which effectively scavenges dissolved oxygen (DO), microfluidic devices have been fabricated where oxygen was rapidly depleted from the microfluidic chamber. It is shown that hypoxic and anaerobic conditions can be generated through the inherent scavenging property of the material itself, without any additional chemical additives.

  • Platelet count kinetics following Interruption of antiretroviral treatment: Results from the SMART study.
  • 2013
  • Ingår i: AIDS. - 1473-5571. ; 27:1, s. 59-68
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: To investigate the mechanisms of platelet kinetics in the SMART study that demonstrated excess mortality with CD4 guided episodic antiretroviral therapy (ART) (drug conservation [DC]) compared to continuous treatment (viral suppression [VS]). Follow up analyses of stored plasma samples demonstrated increased activation of both inflammatory and coagulation pathways after stopping ART. DESIGN: SMART patients from sites that determined platelets routinely. METHODS: Platelet counts were retrospectively collected from 2206 patients from visits at study entry, and during follow-up. D-dimer levels were measured at study entry, month 1, and 2. RESULTS:: Platelet levels decreased in the DC group following randomization, but remained stable in the VS group [median (IQR) decline from study entry to month 4: -24,000/μL(-54,000-4,000) vs. 3000 (-22,000-24,000), respectively, p < 0.0001)] and the rate of developing thrombocytopenia (<100,000/μL) was significantly higher in the DC versus the VS arm (unadjusted DC/VS HR (95%CI) = 1.8 (1.2-2.7)). The decline in platelet count among DC participants on fully suppressive ART correlated with the rise in D-dimer from baseline to either month 1 or 2 (r = -0.41; p = 0.02). Among DC participants who resumed ART 74% recovered to their study entry platelet levels. CONCLUSION: Interrupting ART increases the risk of thrombocytopenia, but re-initiation of ART typically reverses it. Factors contributing to declines in platelets after interrupting ART may include activation of coagulation pathways or HIV-1 replication itself. The contribution of platelets in HIV-related pro-coagulant activity requires further study.
