Tidskriftsartikel (refereegranskat)abstract
- Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data.

Tidskriftsartikel (refereegranskat)abstract
- The main goal of the COVIDENZA trial is to evaluate if inhibition of testosterone signalling by enzalutamide can improve the outcome of patients hospitalised for COVID-19. The hypothesis is based on the observation that the majority of patients in need of intensive care are male, and the connection between androgen receptor signalling and expression of TMPRSS2, an enzyme important for SARS-CoV-2 host cell internalization.Hospitalised COVID-19 patients will be randomised (2:1) to enzalutamide plus standard of care vs. standard of care designed to identify superiority.Included participants, men or women above 50 years of age, must be hospitalised for PCR confirmed COVID-19 symptoms and not in need of immediate mechanical ventilation. Major exclusion criteria are breast-feeding or pregnant women, hormonal treatment for prostate or breast cancer, treatment with immunosuppressive drugs, current symptomatic unstable cardiovascular disease (see Additional file 1 for further details). The trial is registered at Umeå University Hospital, Region Västerbotten, Sweden and 8 hospitals are approved for inclusion in Sweden.Patients randomised to the treatment arm will be treated orally with 160 mg (4x40 mg) enzalutamide (Xtandi®) daily, for five consecutive days. The study is not placebo controlled. The comparator is standard of care treatment for patients hospitalised with COVID-19.The primary endpoints of the study are (time to) need of mechanical ventilation or discharge from hospital as assessed by a clinical 7-point ordinal scale (up to 30 days after inclusion).Randomisation was stratified by center and sex. Each strata was randomized separately with block size six with a 2:1 allocation ratio (enzalutamide + "standard of care": "standard of care"). The randomisation list, with consecutive subject numbers, was generated by an independent statistician using the PROC PLAN procedure of SAS version 9.4 software (SAS Institute, Inc, Cary, North Carolina) BLINDING (MASKING): This is an open-label trial.The trial is designed to have three phases. The first, an exploration phase of 45 participants (30 treatment and 15 control) will focus on safety and includes a more extensive laboratory assessment as well as more frequent safety evaluation. The second prolongation phase, includes the first 100 participants followed by an interim analysis to define the power of the study. The third phase is the continuation of the study up to maximum 600 participants included in total.The current protocol version is COVIDENZA v2.0 as of September 10, 2020. Recruitment started July 29, 2020 and is presently in safety pause after the first exploration phase. Recruitment is anticipated to be complete by 31 December 2021.Eudract number 2020-002027-10 ClinicalTrials.gov Identifier: NCT04475601 , registered June 8, 2020 FULL PROTOCOL: The full protocol is attached as an additional file, accessible from the Trials website (Additional file 1). In the interest in expediting dissemination of this material, the familiar formatting has been eliminated; this Letter serves as a summary of the key elements of the full protocol.

- IntroductionUterine rupture is an obstetric emergency associated with maternal and neonatal morbidity. The main risk factor is a prior cesarean section, with rupture occurring in subsequent labor. The aim of this study was to assess the risk of uterine rupture by labor duration and labor management.Material and methodsThis is a Swedish register-based cohort study of women who underwent labor in 2013–2018 after a primary cesarean section (n = 20 046). Duration of labor was the main exposure, calculated from onset of regular labor contractions and birth; both timepoints were retrieved from electronic medical records for 12 583 labors, 63% of the study population. Uterine rupture was calculated as events per 1000 births at different timepoints during labor. Risk estimates for uterine rupture by labor duration, induction of labor, use of oxytocin and epidural analgesia were calculated using Poisson regression, adjusted for maternal and birth characteristics. Estimates were presented as adjusted rate ratios (ARR) with 95% confidence intervals (CI).ResultsThe prevalence of uterine rupture was 1.4% (282/20 046 deliveries). Labor duration was 9.88 hours (95% CI 8.93–10.83) for women with uterine rupture, 8.20 hours (95% CI 8.10–8.31) for women with vaginal delivery, and 10.71 hours (95% CI 10.46–10.97) for women with cesarean section without uterine rupture. Few women (1.0/1000) experienced uterine rupture during the first 3 hours of labor. Uterine rupture occurred in 15.6/1000 births with labor duration over 12 hours. The highest risk for uterine rupture per hour compared with vaginal delivery was observed at 6 hours (ARR 1.20, 95% CI 1.11–1.30). Induction of labor was associated with uterine rupture (ARR 1.54, 95% CI 1.19–1.99), with a particular high risk seen in those induced with prostaglandins and no risk observed with cervical catheter (ARR 1.19, 95% CI 0.83–1.71). Labor augmentation with oxytocin (ARR 1.60, 95% CI 1.25–2.05) and epidural analgesia (ARR 1.63, 95% CI 1.27–2.10) were also associated with uterine rupture.ConclusionsLabor duration is an independent factor for uterine rupture among women attempting vaginal delivery after cesarean section. Medical induction and augmentation of labor increase the risk, regardless of maternal and birth characteristics.

Tidskriftsartikel (refereegranskat)abstract
- The majority of genetic risk variants for type 2 diabetes (T2D) affect insulin secretion, but the mechanisms through which they influence pancreatic islet function remain largely unknown. We functionally characterized human islets to determine secretory, biophysical, and ultrastructural features in relation to genetic risk profiles in diabetic and nondiabetic donors. Islets from donors with T2D exhibited impaired insulin secretion, which was more pronounced in lean than obese diabetic donors. We assessed the impact of 14 disease susceptibility variants on measures of glucose sensing, exocytosis, and structure. Variants near TCF7L2 and ADRA2A were associated with reduced glucose-induced insulin secretion, whereas susceptibility variants near ADRA2A, KCNJ11, KCNQ1, and TCF7L2 were associated with reduced depolarization-evoked insulin exocytosis. KCNQ1, ADRA2A, KCNJ11, HHEX/IDE, and SLC2A2 variants affected granule docking. We combined our results to create a novel genetic risk score for β-cell dysfunction that includes aberrant granule docking, decreased Ca(2+) sensitivity of exocytosis, and reduced insulin release. Individuals with a high risk score displayed an impaired response to intravenous glucose and deteriorating insulin secretion over time. Our results underscore the importance of defects in β-cell exocytosis in T2D and demonstrate the potential of cellular phenotypic characterization in the elucidation of complex genetic disorders.

- The dipeptide amide H-Phe-Phe-NH2 (1) that previously was identified as a ligand for the substance P 1-7 (SP1-7) binding site exerts intriguing results in animal models of neuropathic pain after central but not after peripheral administration. The dipeptide 1 is derived from stepwise modifications of the anti-nociceptive heptapeptide SP1-7 and the tetrapeptide endomorphin-2 that is also binding to the SP1-7 site. We herein report a strong anti-allodynic effect of a new H-Phe-Phe-NH2 peptidomimetic (4) comprising an imidazole ring as a bioisosteric element, in the spare nerve injury (SNI) mice model after peripheral administration. Peptidomimetic 4 was stable in plasma, displayed a fair membrane permeability and a favorable neurotoxic profile. Moreover, the effective dose (ED50) of 4 was superior as compared to gabapentin and morphine that are used in clinic.

- Background: Men are more severely affected by COVID-19. Testosterone may influence SARS-CoV-2 infection and the immune response.Objective: To clinically, epidemiologically, and experimentally evaluate the effect of antiandrogens on SARS-CoV-2 infection.Designs, settings, and participants: A randomized phase 2 clinical trial (COVIDENZA) enrolled 42 hospitalized COVID-19 patients before safety evaluation. We also conducted a population-based retrospective study of 7894 SARS-CoV-2–positive prostate cancer patients and an experimental study using an air-liquid interface three-dimensional culture model of primary lung cells.Intervention: In COVIDENZA, patients were randomized 2:1 to 5 d of enzalutamide or standard of care.Outcome measurements: The primary outcomes in COVIDENZA were the time to mechanical ventilation or discharge from hospital. The population-based study investigated risk of hospitalization, intensive care, and death from COVID-19 after androgen inhibition.Results and limitations: Enzalutamide-treated patients required longer hospitalization (hazard ratio [HR] for discharge from hospital 0.43, 95% confidence interval [CI] 0.20–0.93) and the trial was terminated early. In the epidemiological study, no preventive effects were observed. The frail population of patients treated with androgen deprivation therapy (ADT) in combination with abiraterone acetate or enzalutamide had a higher risk of dying from COVID-19 (HR 2.51, 95% CI 1.52–4.16). In vitro data showed no effect of enzalutamide on virus replication. The epidemiological study has limitations that include residual confounders.Conclusions: The results do not support a therapeutic effect of enzalutamide or preventive effects of bicalutamide or ADT in COVID-19. Thus, these antiandrogens should not be used for hospitalized COVID-19 patients or as prevention for COVID-19. Further research on these therapeutics in this setting are not warranted.Patient summary: We studied whether inhibition of testosterone could diminish COVID-19 symptoms. We found no evidence of an effect in a clinical study or in epidemiological or experimental investigations. We conclude that androgen inhibition should not be used for prevention or treatment of COVID-19.

Tidskriftsartikel (refereegranskat)abstract
- Low grade inflammation in obesity is associated with accumulation of the macrophagederived cytokine osteopontin in adipose tissue and induction of local as well as systemic insulin resistance. Since GIP (glucose-dependent insulinotropic polypeptide) is a strong stimulator of adipogenesis and may play a role in the development of obesity, we explored whether GIP directly would stimulate osteopontin (OPN) expression in adipose tissue and thereby induce insulin resistance. GIP stimulated OPN protein expression in a dose-dependent fashion in rat primary adipocytes. The level of OPN mRNA was higher in adipose tissue of obese individuals (0.13±}0.04 vs 0.04±}0.01, P<0.05) and correlated inversely with measures of insulin sensitivity (r=-0.24, P=0.001). A common variant of the GIP receptor (GIPR) (rs10423928) gene was associated with lower amount of the exon 9 containing isoform required for transmembrane activity. Carriers of the A-allele with a reduced receptor function showed lower adipose tissue OPN mRNA levels and better insulin sensitivity. Together, these data suggest a role for GIP not only as an incretin hormone, but also as a trigger of inflammation and insulin resistance in adipose tissue. Carriers of GIPR rs10423928 A-allele showed protective properties via reduced GIP effects. Identification of this unprecedented link between GIP and OPN in adipose tissue might open new avenues for therapeutic interventions.

- INTRODUCTION: Induction of labor is increasing in the world. A common indication for Induction of labor is late term and postterm pregnancy at 41 gestational week and thereafter. We aimed to evaluate if there are any differences regarding efficacy, safety, and women's childbirth experience between oral misoprostol and transvaginal balloon catheter for cervical ripening in women with a low-risk singleton pregnancy and induction of labor at 41+0 to 42+0-1 gestational weeks.MATERIAL AND METHODS: In this observational study, based on data from Swedish Postterm Induction Study (SWEPIS), a multicenter randomized controlled trial, a total of 1 213 women with a low-risk singleton pregnancy at 41 to 42 gestational weeks were induced with oral misoprostol (n=744) or transvaginal balloon catheter (n=469) at 15 Swedish delivery hospitals. The primary efficacy outcome was vaginal delivery within 24 hours and primary safety outcomes were neonatal and maternal composite adverse outcomes. Secondary outcomes included time-to-vaginal delivery and mode of delivery. Women's childbirth experience was assessed with the Childbirth Experience Questionnaire (CEQ 2.0) and visual analogue scale. We present crude and adjusted mean differences and relative risks (RR) with 95% confidence interval (CI). Adjustment was performed for a propensity score based on delivery hospital and baseline characteristics including Bishop score.RESULTS: Vaginal delivery within 24 hours was significantly lower in the misoprostol compared with the balloon catheter group (46.5% [346/744] vs 62.7% [294/469]; adjusted RR 0.76 [95% CI 0.64; 0.89]). Primary neonatal and maternal safety outcomes did not differ between groups (neonatal composite 3.5% [36/744] vs 3.2% [15/469]; adjusted RR 0.77 [95% CI 0.31; 1.89]; maternal composite (2.3% [17/744] vs 1.9% [9/469]; adjusted RR 1.70 [95% CI 0.58; 4.97]). Adjusted mean time-to-vaginal delivery was increased by 3.8 hours (95% CI 1.3; 6.2) in the misoprostol group. Non-operative vaginal delivery and cesarean delivery rates did not differ. Women's childbirth experience was positive overall and similar in both groups.CONCLUSION: Induction of labor with oral misoprostol compared with a transvaginal balloon catheter was associated with a lower probability of vaginal delivery within 24 hours and a longer time-to-vaginal delivery. However, primary safety outcomes, non-operative vaginal delivery and women's childbirth experience were similar in both groups. Therefore, both methods can be recommended in women with low-risk postdate pregnancies.

Underlag till kontrollstation 2015 för anpassning till ett förändrat klimat
- 2015
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- När klimatet förändras påverkas människor och deras egendom, företag, kommunal och statlig verksamhet, vilket gör att såväl myndigheter, kommuner, företag som enskilda fastighetsägare måste agera.Översvämningar, värmeböljor, ras och skred är bara några exempel på vad vi behöver rusta oss för. Vi ska möta klimatförändringar som sker här i Sverige, men vi måste också anpassa oss till vad klimatförändringar i andra länder innebär för Sverige.Kostnaderna för klimatanpassning kan bli höga, men bedöms av bland andra EUkommissionen ändå löna sig i förhållande till de skadekostnader som uppstår om inga åtgärder vidtas.Klimatanpassningsarbetet i Sverige har gått framåt under de senaste åren. Några exempel på myndighetsuppdrag är Nationell höjddatabas, Ras- och skredkarteringen av Göta älvdalen, Dricksvattenutredningen, länsstyrelsernas regionala handlingsplaner för klimatanpassning, samt inrättandet av Nationellt kunskapscentrum för klimatanpassning.Sveriges meteorologiska och hydrologiska instituts arbete med regeringsuppdraget att utarbeta underlag till kontrollstation 2015 för anpassning till ett förändrat klimat, visar på stort behov av fortsatta insatser. Denna rapport ger förslag till en färdplan för klimatanpassningen i Sverige. Slutsatserna handlar framförallt om att arbetet måste bedrivas långsiktigt, att roller och mandat förtydligas samt att en bättre samordning mellan olika aktörer uppnås.De viktigaste slutsatserna för fortsatt arbete är:Regelverk behöver anpassas, roller och ansvar samt strategier och mål måstetydliggörasPrioriterade forsknings- och utvecklingsinsatser, som fyller identifierade kunskapsbehov inklusive långtidsövervakning, behöver finansierasKunskap, beslutstöd och prognos- och varningssystem behöver göras mer tillgängligaHur kostnader ska fördelas mellan olika aktörer och hur resurser till prioriterade åtgärder ska säkerställas, behöver klarläggasUppdraget har inneburit att sammanställa kunskap om nuvarande och framtida risker och konsekvenser för samhället av ett förändrat klimat, till exempel effekter på samhällsviktiga funktioner och människors hälsa. Arbetet har också omfattat en kartläggning över vad som genomförts sedan Klimat- och sårbarhetsutredningen presenterades år 2007. Utifrån det underlaget har målet varit att beskriva behoven och lämna förslag på åtgärder för anpassning av olika delar av samhället. Hänsyn har tagits till EU:s strategi för klimatanpassning. Arbetet har bedrivits i bred samverkan med myndigheter, kommuner, forskare, branschorganisationer och andra näringslivsrepresentanter.Redovisningen av uppdraget omfattar en huvudrapport samt 18 bilagor. Huvudrapportens tredje kapitel är en syntes av rapportens alla förslag, och kan ses som färdplanen för att säkerställa att Sverige klimatanpassas.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- SlutsatserTyp 1- och typ 2-diabetes Det finns ett samband mellan att äta medelhavskost och lägre risk att dö i förtid oavsett orsak (måttlig tillförlitlighet). Det finns ett samband mellan att äta en större andel2 fibrer eller baljväxter och lägre risk att dö i förtid oavsett orsak (måttlig tillförlitlighet). Det kan även finnas ett samband mellan att äta en större andel nötter och lägre risk att dö i förtid oavsett orsak (låg tillförlitlighet) samt lägre risk att insjukna i hjärt- och kärlsjukdom (låg tillförlitlighet). Det finns ett samband mellan att dricka mer2 kaffe och lägre risk att dö i förtid oavsett orsak och lägre risk att dö i förtid i kranskärlssjukdom (måttlig tillförlitlighet) samt möjligen en lägre risk att dö i förtid i hjärt- och kärlsjukdom (låg tillförlitlighet). Det råder generell brist på studier med lång uppföljningstid som jämför inverkan av olika slags kostråd på överlevnad, diabeteskomplikationer, diabetesremission3, livskvalitet och biverkningar. Tillförlitligheten av befintliga resultat är dessutom mycket låg för de flesta koster, kostbehandlingar, livsmedel och näringsämnen som har utvärderats. Effekter på hälsa och relaterade mått kan i dessa fall inte bedömas.2. Begreppet ”större andel” eller ”mer” avser inte nödvändigtvis att äta eller dricka mer totalt utan att öka mängden av ett visst livsmedel genom att byta ut annan mat eller dryck.Typ 2-diabetes Det kan finnas ett samband mellan att äta en större andel mättat fett och högre risk för att dö i förtid av hjärt- och kärlsjukdom (låg tillförlitlighet). Det kan även finnas ett samband mellan att äta en större andel enkelomättat fett och lägre risk att dö i förtid oavsett orsak (låg tillförlitlighet). En behandling med en initial period av kraftigt minskat energiintag med hjälp av lågenergipulver (VLED) med efterföljande övergång till mat för viktstabilitet jämfört med vanlig kostbehandling har gynnsamma effekter på livskvalitet (enligt EQ-5D), långtidsblodsocker (HbA1c) och vikt upp till 12 månader (måttlig tillförlitlighet)4. Vidare kan metoder där VLED ingår ha gynnsamma effekter på diabetesremission5 och midjeomfång upp till 12 månader (låg tillförlitlighet) och långtidsblodsocker (HbA1c) upp till 24 månader (låg tillförlitlighet). Intensiv livsstilsbehandling därlågfettkost kombineras med fysisk aktivitet och minskat energiintag har gynnsamma effekter jämfört med vanlig kostbehandling på långtidsblodsocker (HbA1c), vikt, kroppsmasseindex (BMI), midjeomfång och vissa blodfetter upp till 12 månader (måttlig tillförlitlighet)3. Viktminskningen kan kvarstå upp till omkring 10 år (låg tillförlitlighet). Behandlingen kan leda till bättre fysisk livskvalitet upp till 8 år (låg tillförlitlighet) medan effektskillnaden i psykisk livskvalitet under samma tid kan vara obefintlig eller försumbar (låg tillförlitlighet). Jämförelsen påvisar ingen förändrad risk att dö i förtid oavsett orsak eller att dö eller insjukna av kardiovaskulära orsaker efter omkring 10 år (låg tillförlitlighet). I det hälsoekonomiska perspektivet är intensiv livsstilsbehandling mer resurskrävande än vanlig kostbehandling, och beräkningar visar små eller inga vinster i kvalitetsjusterade levnadsår (QALYs) på individnivå. Energirestriktion i samband med intensiv livsstilsbehandling med ketogen kost eller med högproteinkost (20 E%) i kombination med fysisk aktivitet jämfört med vanlig kostbehandling kan ge en viktminskning upp till 11 månader (låg tillförlitlighet) men det saknas studier som kan visa om vikten kan bibehållas på längre sikt. Det saknas studier som undersökt kliniskt viktiga utfall som dödlighet, kardiovaskulära sjukdomar, livskvalitet och diabetesremission.3. Gäller endast vid typ 2-diabetes.4. Utgår från individer med en medelkroppsvikt på cirka 100 kg och medel-HbA1c på 60 mmol/mol.5. Resultaten för utfallet diabetesremission (att uppnå normala blodsockervärden) gäller när en diabetesdiagnos sattes för mindre än 6 år sedan eller för mindre än 3 år sedan. Definitionen för diabetesremission var ett HbA1c på mindre än 48 mmol/mol och att samtidigt vara fri från blodsockersänkande läkemedel.Graviditetsdiabetes Det saknas studier om kost vid graviditetsdiabetes med tillräcklig tillförlitlighet för att kunna bedöma effekterna.

- Biology is increasingly dependent on large-scale analysis, such as proteomics, creating a requirement for efficient bioinformatics. Bioinformatic predictions of biological functions rely upon correctly annotated database sequences, and the presence of inaccurately annotated or otherwise poorly described sequences introduces noise and bias to biological analyses. Accurate annotations are, for example, pivotal for correct identifications of polypeptide fragments. However, standards for how sequence databases are organized and presented are currently insufficient. Here, we propose five strategies to address fundamental issues in the annotation of sequence databases: (i) to clearly separate experimentally verified and unverified sequence entries; (ii) to enable a system for tracing the origins of annotations; (iii) to separate entries with high-quality, informative annotation from less useful ones; (iv) to integrate automated quality-control software whenever such tools exist; and (v) to facilitate post-submission editing of annotations and metadata associated with sequences. We believe that implementation of these strategies, for example as requirements for publication of database papers, would enable biology to better take advantage of large-scale data.

- Glucose-dependent insulinotropic polypeptide (GIP) is an incretin hormone with extrapancreatic effects beyond glycemic control. Here we demonstrate unexpected effects of GIP signaling in the vasculature. GIP induces the expression of the pro-atherogenic cytokine osteopontin (OPN) in mouse arteries, via local release of endothelin-1 (ET-1) and activation of cAMP response element binding protein (CREB). Infusion of GIP increases plasma OPN levels in healthy individuals. Plasma ET-1 and OPN levels are positively correlated in patients with critical limb ischemia. Fasting GIP levels are higher in individuals with a history of cardiovascular disease (myocardial infarction, stroke) when compared to controls. GIP receptor (GIPR) and OPN mRNA levels are higher in carotid endarterectomies from patients with symptoms (stroke, transient ischemic attacks, amaurosis fugax) than in asymptomatic patients; and expression associates to parameters characteristic of unstable and inflammatory plaques (increased lipid accumulation, macrophage infiltration and reduced smooth muscle cell content). While GIPR expression is predominantly endothelial in healthy arteries from human, mouse, rat and pig; remarkable up-regulation is observed in endothelial and smooth muscle cells upon culture conditions yielding a "vascular disease-like" phenotype. Moreover, a common variant rs10423928 in the GIPR gene associated with increased risk of stroke in type 2 diabetes patients.

- Background For the past several years pharmacists' responsibilities have expanded globally from traditional tasks of dispensing medications to collaborating with other health care professionals in patient care. Similar developments have not occurred in outpatient settings in Iceland. Objective The aim of this study was to explore Icelandic general practitioners' views on the current status of primary care, their perceptions of pharmacists as a health care profession, and their attitudes towards future GP-pharmacist collaboration in primary care in Iceland. Setting Twelve primary care clinics in Iceland. Methods Semi-structured in-depth interviews were conducted with general practitioners from different primary care clinics in Iceland. A purposive and snowball sampling technique was used to select participants. All interviews were recorded and transcribed verbatim. The transcripts were categorized by themes and then analyzed using conventional content analysis. Main outcome measure General practitioners' attitudes towards pharmacists. Results Twenty general practitioners from twelve different primary care clinics in Iceland were interviewed. There are several unmet needs regarding medicines and patient monitoring in the Icelandic health care system. General practitioners suggested ways in which these gaps may be addressed and pharmacist-led clinical service was one of the suggestions. Currently, their communication with pharmacists in the primary sector solely surrounds practical non-clinical issues. Due to increasing polypharmacy and multimorbidity, they suggested that pharmacists should be more involved in patient care. Conclusions General practitioners believe that pharmacist-led clinical service can increase the quality of patient therapy. To improve communication between these health care providers, pharmacists must also re-professionalize (strengthening the profession´s status through new responsibilities and tasks), not having a conflict of interest and showing that they have expertise in patient care.
