A quality assurance study of the development of quality of care in outpatient clinics for treatment of addiction in Greenland.

INTRODUCTION: In 2016, a new addiction treatment service, Allorfik, was introduced in Greenland. Allorfik has, throughout the implementation and after, used auditing of patient records with feedback to develop the quality of care in treatment. Audits and feedback are routinely done in each treatment center. This study wishes to investigate the development of the quality of treatment through the case notes from the journal audits. METHODOLOGY: This study is based on case notes audits from 2019, 2020 and 2021. In the audits, the focus has been on the quality of documentation and content for ten specific areas in each patient record. Each area was scored on a Likert scale of 0-4 for both outcomes. Statistical analyses were done using Stata 17, and P-values < 0.05 were considered statistically significant. We present baseline characteristics for patients and illustrate the development of quality for both outcomes as time trends with scatter plots. RESULTS: The analysis was based on data from 454 patients and audits of their case notes. The mean number of weeks in treatment is 12.72, and the mean age for the people in the audited case notes is 39. Time had a positive effect on both outcomes, and so each month, documentation increased by 0.21 points (p-value = <0.001), and content increased by 0.27 points (p-value = <0.001). CONCLUSION: For documentation and content, the quality level has increased significantly with time, and the quality of case notes is at an excellent level at the final audits of all treatment centers.

Myocardial perfusion imaging by 15O-H2O positron emission tomography predicts clinical revascularization procedures in symptomatic patients with previous coronary artery bypass graft.

Aims: We wanted to assess if 15O-H2O myocardial perfusion imaging (MPI) in a clinical setting can predict referral to coronary artery catheterization [coronary angiography (CAG)], execution of percutaneous coronary intervention (PCI), and post-PCI angina relief for patients with angina and previous coronary artery bypass graft (CABG). Methods and results: We analysed 172 symptomatic CABG patients referred for 15O-H2O positron emission tomography (PET) MPI at Aarhus University Hospital Department of Nuclear Medicine & PET Centre, of which five did not complete the scan. In total, 145 (87%) enrolled patients had an abnormal MPI. Of these, 86/145 (59%) underwent CAG within 3 months; however, no PET parameters predicted referral to CAG. During the CAG, 25/86 (29%) patients were revascularized by PCI. Relative flow reserve (RFR) (0.49 vs. 0.54 P = 0.03), vessel-specific myocardial blood flow (MBF) (1.53 vs. 1.88 mL/g/min, P < 0.01), and vessel-specific myocardial flow reserve (MFR) (1.73 vs. 2.13, P < 0.01) were significantly lower in patients revascularized by PCI. Receiver operating characteristic analysis of the vessel-specific parameters yielded optimal cutoffs of 1.36 mL/g/min (MBF) and 1.28 (MFR) to predict PCI. Angina relief was experienced by 18/24 (75%) of the patients who underwent PCI. Myocardial blood flow was an excellent predictor of angina relief on both a global [area under the curve (AUC) = 0.85, P < 0.01] and vessel-specific (AUC = 0.90, P < 0.01) level with optimal cutoff levels of 1.99 mL/g/min and 1.85 mL/g/min, respectively. Conclusion: For CABG patients, RFR, vessel-specific MBF, and vessel-specific MFR measured by 15O-H2O PET MPI predict whether subsequent CAG will result in PCI. Additionally, global and vessel-specific MBF values predict post-PCI angina relief.

Screening of coexisting depression or anxiety disorders among Danish patients with alcohol use disorder in outpatient treatment.

BACKGROUND: Depression and anxiety are highly prevalent among patients seeking outpatient treatment for alcohol use disorders (AUD) and if depression and anxiety are addressed the prognosis is improved. Screening instruments for depression and anxiety have been validated in populations suffering from drug use disorders, but not in populations suffering from AUD. The aim of this study was to validate four self-administrated screening instruments (PHQ-9, GAD-7, Kessler-6, and SRQ) and calculate the optimal cut-off value for identifying depression and anxiety. METHODS: The study included 73 patients with self-reported depression or anxiety during AUD treatment. Each patient filled out the above-mentioned instruments and was subsequently interviewed by trained clinicians blinded to the results of the instruments with the Present State Examination to establish a diagnosis of depression or anxiety according to ICD-10. ROC curves were constructed for each instrument and the area under the curve (AUC) was calculated using patients with no depression or anxiety as reference. Youden's index was calculated to assess the optimal cut-off for each instrument. RESULTS: A total of 33 (45.2%) were diagnosed with depression or anxiety. The AUC for PHQ-9, GAD-7, Kessler-6, and SRQ were 0.767, 0.630, 0.793, and 0.698 respectively. Kessler-6, the instruments performing best based on the AUC, identified 27 (82%) of the 33 patients using a cut-off of 10 points. CONCLUSION: Kessler-6 seems to be valid and reliable in identifying patients requiring treatment for depression or anxiety among patients seeking treatment for AUD who are reporting depression or anxiety.

PrehospitaL Ultrasound in Undifferentiated DyspnEa (PreLUDE): a prospective, clinical, observational study.

BACKGROUND: Diagnostic uncertainty in patients with dyspnea is associated with worse outcomes. We hypothesized that prehospital point-of-care ultrasound (POCUS) can improve diagnostic accuracy. METHODS: Prospective observational study of adult patients suffering dyspnea. Prehospital critical care physicians registered a suspected diagnosis based on clinical examination alone, performed POCUS of the heart and lungs, and finally registered suspected diagnoses based on their clinical examination supplemented with POCUS. Pre- and post-POCUS diagnoses were compared to endpoint committee adjudicated diagnoses. The primary outcome was improved sensitivity for diagnosing acute heart failure. Secondary outcomes included other diagnostic accuracy measures in relation to acute heart failure and other causes of dyspnea. RESULTS: In total, 214 patients were included. The diagnosis of acute heart failure was suspected in 64/214 (30%) of patients before POCUS and 64/214 (30%) patients after POCUS, but POCUS led to reclassification in 53/214 (25%) patients. The endpoint committee adjudicated the diagnosis of acute heart failure in 87/214 (41%) patients. The sensitivity for the diagnosis of acute heart failure was 58% (95% CI 46%-69%) before POCUS compared to 65% (95% CI 53%-75%) after POCUS (p = 0.12). ROC AUC for the diagnosis acute heart failure was 0.72 (95% CI 0.66-0.78) before POCUS compared to 0.79 (0.73-0.84) after POCUS (p < 0.001). ROC AUC for the diagnosis acute exacerbation (AE) of chronic obstructive pulmonary disease (COPD) or asthma was 0.87 (0.82-0.91) before POCUS and 0.93 (0.88-0.97) after POCUS (p < 0.001). A POCUS finding of any of severely reduced left ventricular function, bilateral B-lines or bilateral pleural effusion demonstrated the highest sensitivity for acute heart failure at 88% (95% CI 79%-94%), whereas the combination of all of these three findings yielded the highest specificity at 99% (95% CI 95%-100%). CONCLUSION: Supplementary prehospital POCUS leads to an improvement of diagnostic accuracy of both heart failure and AE-COPD/-asthma overall described by ROC AUC, but the increase in sensitivity for the diagnoses of acute heart failure did not reach statistical significance. Tailored use of POCUS findings optimizes diagnostic accuracy for rule-out and rule-in of acute heart failure.

Investigating effects of sodium beta-hydroxybutyrate on metabolism in placebo-controlled, bilaterally infused human leg with focus on skeletal muscle protein dynamics.

Systemic administration of beta-hydroxybutyrate (BHB) decreases whole-body protein oxidation and muscle protein breakdown in humans. We aimed to determine any direct effect of BHB on skeletal muscle protein turnover when administered locally in the femoral artery. Paired design with each subject being investigated on one single occasion with one leg being infused with BHB and the opposing leg acting as a control. We studied 10 healthy male volunteers once with bilateral femoral vein and artery catheters. One artery was perfused with saline (Placebo) and one with sodium-BHB. Labelled phenylalanine and palmitate were used to assess local leg fluxes. Femoral vein concentrations of BHB were significantly higher in the intervention leg (3.4 (3.2, 3.6) mM) compared with the placebo-controlled leg (1.9 (1.8, 2.1) mM) with a peak difference of 1.4 (1.1, 1.7) mM, p < 0.0005. Net loss of phenylalanine for BHB vs Placebo -6.7(-10.8, -2.7) nmol/min vs -8.7(-13.8, -3.7) nmol/min, p = 0.52. Palmitate flux and arterio-venous difference of glucose did not differ between legs. Under these experimental conditions, we failed to observe the direct effects of BHB on skeletal muscle protein turnover. This may relate to a combination of high concentrations of BHB (close to 2 mM) imposed systemically by spillover leading to high BHB concentrations in the saline-infused leg and a lack of major differences in concentration gradients between the two sides-implying that observations were made on the upper part of the dose-response curve for BHB and the relatively small number of subjects studied.

The association between weight loss and long term development in quality-of-life among children living with obesity: a pragmatic descriptive intervention study.

BACKGROUND: Childhood obesity is associated with impaired Quality-of-Life (QoL), increased stigmatization and higher risk of development of depression compared to their peers. This report describes the long-term development in QoL for cohort of children with obesity after a sustainable weight reduction. METHODS: This pragmatic descriptive intervention study enrolled 120 children with obesity, age 5-17 years, in a multifactorial lifestyle intervention. The intervention was an across sectors collaboration between a department of pediatrics and community health care workers. QoL was assessed yearly throughout the intervention and evaluated by a 6-item Visual Analogue Scale (VAS). For analyzing changes in VAS, as function BMI-SDS, regression models were used, while ANOVA and Wilcoxon test were applied for normal and not-normal distributed data. 95% confidence interval not containing 0 and p-value < 0.05 was considered statistically significant. RESULTS: After 26.4 months (13.9 SD) an overall decrease in bullying (0.6 vs. 0.0 median) and motivation (10.0 vs. 9.6) was observed. QoL increased in children with a BMI-SDS reduction (0.65 (2.49 SD)) opposite children with no-change or increasing BMI-SDS who reported reduced QoL (-0.36 (1.55 SD) and -0.96 (2.27 SD)). A significant inverse relationship was observed for Joy of Life, QoL and body perception as a function of BMI-SDS per year. CONCLUSION: Weight reduction causes improvement in QoL for children with obesity and an inverse relationship for QoL and changing BMI-SDS / year was establish.

[Alcohol, anxiety, and depression].

Anxiety, depression, and co-morbid alcohol use disorder (AUD) are frequent and often difficult to diagnose and treat accurately. Diagnosis of anxiety or depression should only be made when the patients have been abstinent for four to six weeks. Patients are treated in general practice, municipal alcohol outpatient clinics, or in psychiatric settings. There are no national guidelines for this organisation in Denmark. Integrated treatment (psychotherapy and/or medical), at which both anxiety or depression and AUD are treated simultaneously by the same therapist (team), seems to be best.

Abnormal mitochondrial function and morphology in heart transplanted patients with cardiac allograft vasculopathy.

BACKGROUND: Cardiac allograft vasculopathy (CAV) remains the Achilles' heel of long-term survival of HTx patients. Mitochondrial dysfunction has been reported in both arteriosclerotic coronary disease and heart failure. However, myocardial mitochondrial function has not been examined in HTx patients with CAV. METHODS: 43 HTx patients (21 patients with CAV and 22 patients without CAV) ≥12 months after HTx were enrolled. Endomyocardial biopsies were analyzed using high-resolution respirometry for glucose-coupled mitochondrial respiration. Number and area of mitochondria profiles as well as cristae morphology were assessed by transmission electron microscopy. Echocardiography and coronary angiography were used to measure global longitudinal strain (GLS) and grade CAV. RESULTS: Complex I+II-linked respiration was reduced in patients with CAV compared with patients without CAV (82.7 ± 31.9 pmol O2/(s•mg) vs 116 ± 35.9 pmol O2/(s•mg), p = 0.003). Mitochondrial respiratory function measured as oxidative phosphorylation coupling efficiency was positively associated with left ventricular GLS (r = 0.49, p = 0.002) and negatively associated with elevated biomarkers (Troponin T: r=-0.33, p = 0.04 and NT-proBNP: r = -0.41, p = 0.009). Mitochondrial profile number and area did not differ. However, patients with CAV had a larger proportion of mitochondria with abnormal cristae morphology (p < 0.001). CONCLUSIONS: Myocardial mitochondrial respiration is impaired in patients with CAV and is associated with an abnormal cristae morphology. The mitochondrial dysfunction appears to be associated with reduced myocardial contractile function and elevated biomarkers. These results highlight that mitochondrial targeted treatment in patients with CAV should be assessed in future clinical studies.

Relapse prevention for alcohol use disorders: combined acamprosate and cue exposure therapy as aftercare.

AIMS: Many patients with alcohol use disorders are challenged by cravings leading to repeated relapses. Both cue exposure therapy (CET) and acamprosate target alcohol cravings and are often combined (CET + acamprosate). The main aim of this study was to investigate whether aftercare treatment consisting of CET combined with acamprosate is equivalent to (A) CET as monotherapy, (B) aftercare as usual (AAU) as monotherapy or (C) AAU combined with acamprosate. METHODS: Patients were randomized to receive either CET with urge-specific coping skills (USCS) as aftercare or AAU. Acamprosate prescription data were extracted from patient case records. Alcohol consumption, cravings, and USCS were assessed at pre-aftercare, post-aftercare, and 6-month follow-up. RESULTS: Overall, patients increased their alcohol consumption during and following aftercare treatment, thereby relapsing despite any treatment. However, CET + acamprosate achieved greater abstinence compared to AAU + acamprosate at follow-up (p=.047). CET + acamprosate also reduced number of drinking days (p=.020) and number of days with excessive drinking (p=.020) at post-aftercare, when compared to AAU monotherapy. CET monotherapy increased sensible drinking at post-aftercare compared to AAU monotherapy (p=.045) and AAU + acamprosate (p=.047). Only CET monotherapy showed improvement in cravings, when compared to AAU at follow-up (mean urge level: p=.032; peak urge level: p=.014). CONCLUSION: The study showed that CET both as monotherapy and combined with acamprosate was superior to AAU monotherapy and AAU + acamprosate in reducing alcohol consumption. Only CET + acamprosate was capable of reducing alcohol consumption in the longer term, indicating that anti-craving medication may not impede CET from exerting an effect on alcohol consumption.

The impact of free choice in alcohol treatment. Primary outcomes of the self-match study.

INTRODUCTION: A paternalistic approach to treatment planning is common, but there is a growing interest in involving clients in the planning of their own treatment, both in medical care and psychotherapy. Several studies on matching patients to treatment have failed to improve outcome. Studies on Shared Decision-Making in mental health are encouraging but somewhat ambiguous in addiction treatment. OBJECTIVE: This study investigated whether self-matching (Informed Choice) to treatment improves alcohol consumption, retention, and quality of life. METHOD: 402 consecutive clients (female 46.7 %, mean age 47.4) seeking treatment for alcohol use disorder at the outpatient clinic in Odense, Denmark were enrolled in this single-blinded randomized controlled trial. Clients randomized to the intervention group watched an 8-minute video presentation of the treatments and then chose the treatment they preferred. Clients in the treatment as usual (TAU) group were allocated to treatment by an evidence-based algorithm. Measurements on alcohol consumption, quality of life, and retention in care were completed at baseline and 6-month follow-up. RESULTS: There was no significant difference on primary and secondary outcome measures between the Informed Choice group and TAU group at 6-month follow-up. 80 % of clients in the Informed Choice group were satisfied with being randomized to self-matching whereas 24 % in the TAU group were satisfied with being assigned by expert matching. CONCLUSION: Our hypothesis, that outcome is improved if clients choose their own treatment, was not supported. However, an important finding is that client self-matching is just as beneficial as expert matching.

Echocardiographic parameters during prolonged targeted temperature Management in out-of-hospital Cardiac Arrest Survivors to predict neurological outcome - a post-hoc analysis of the TTH48 trial.

BACKGROUND: Transthoracic echocardiographic (TTE) indices of myocardial function among survivors of out-of-hospital cardiac arrest (OHCA) have been related to neurological outcome; however, results are inconsistent. We hypothesized that changes in average peak systolic mitral annular velocity (s') from 24 h (h) to 72 h following start of targeted temperature management (TTM) predict six-month neurological outcome in comatose OHCA survivors. METHODS: We investigated the association between peak systolic velocity of the mitral plane (s') and six-month neurological outcome in a population of 99 patients from a randomised controlled trial comparing TTM at 33 ± 1 °C for 24 h (h) (n = 47) vs. 48 h (n = 52) following OHCA (TTH48-trial). TTE was conducted at 24 h, 48 h, and 72 h after reaching target temperature. The primary outcome was 180 days neurological outcome assessed by Cerebral Performance Category score (CPC180) and the primary TTE outcome measure was s'. Secondary outcome measures were left ventricular ejection fraction (LVEF), global longitudinal strain (GLS), e', E/e' and tricuspid annular plane systolic excursion (TAPSE). RESULTS: Across all three scan time points s' was not associated with neurological outcome (ORs: 24 h: 1.0 (95%CI: 0.7-1.4, p = 0.98), 48 h: 1.13 (95%CI: 0.9-1.4, p = 0.34), 72 h: 1.04 (95%CI: 0.8-1.4, p = 0.76)). LVEF, GLS, E/e', and TAPSE recorded on serial TTEs following OHCA were neither associated with nor did they predict CPC180. Estimated median e' at 48 h following TTM was 5.74 cm/s (95%CI: 5.27-6.22) in patients with good outcome (CPC180 1-2) vs. 4.95 cm/s (95%CI: 4.37-5.54) in patients with poor outcome (CPC180 3-5) (p = 0.04). CONCLUSIONS: s' assessed on serial TTEs in comatose survivors of OHCA treated with TTM was not associated with CPC180. Our findings suggest that serial TTEs in the early post-resuscitation phase during TTM do not aid the prognostication of neurological outcome following OHCA. TRIAL REGISTRATION: NCT02066753 .

SGLT2 Inhibition Does Not Affect Myocardial Fatty Acid Oxidation or Uptake, but Reduces Myocardial Glucose Uptake and Blood Flow in Individuals With Type 2 Diabetes: A Randomized Double-Blind, Placebo-Controlled Crossover Trial.

Sodium-glucose cotransporter 2 (SGLT2) inhibition reduces cardiovascular morbidity and mortality in individuals with type 2 diabetes. Beneficial effects have been attributed to increased ketogenesis, reduced cardiac fatty acid oxidation, and diminished cardiac oxygen consumption. We therefore studied whether SGLT2 inhibition altered cardiac oxidative substrate consumption, efficiency, and perfusion. Thirteen individuals with type 2 diabetes were studied after 4 weeks' treatment with empagliflozin and placebo in a randomized, double-blind, placebo-controlled crossover study. Myocardial palmitate and glucose uptake were measured with 11C-palmitate and 18F-fluorodeoxyglucose positron emission tomography (PET)/computed tomography (CT). Oxygen consumption and myocardial external efficiency (MEE) were measured with 11C-acetate PET/CT. Resting and adenosine stress myocardial blood flow (MBF) and myocardial flow reserve (MFR) were measured using 15O-H2O PET/CT. Empagliflozin did not affect myocardial free fatty acids (FFAs) uptake but reduced myocardial glucose uptake by 57% (P < 0.001). Empagliflozin did not change myocardial oxygen consumption or MEE. Empagliflozin reduced resting MBF by 13% (P < 0.01), but did not significantly affect stress MBF or MFR. In conclusion, SGLT2 inhibition did not affect myocardial FFA uptake, but channeled myocardial substrate utilization from glucose toward other sources and reduced resting MBF. However, the observed metabolic and hemodynamic changes were modest and most likely contribute only partially to the cardioprotective effect of SGLT2 inhibition.

Implementation of AUDIT in the treatment planning process for alcohol use disorder in Greenland.

INTRODUCTION: The aim was to describe the treatment-seeking population with alcohol use disorder by means of data from the AUDIT questionnaire at referral and to evaluate and discuss if this information can be of use in treatment and service planning. METHODS: Data from 2016 to 2018 were extracted from the National Database on Substance Abuse Treatment. The sample included 1281 individual treatment seekers from all over Greenland. RESULTS: Mean age was 38.2 years (SD 12.1 years). Only 60.1% had a total AUDIT score suggesting dependency, and 15.5% had a harmful use. While most only drank 2-4 times a month, about 95% binge drank. Half reported loss of control at least weekly, and one of three had been unable to do what was expected of them, or needed a drink first thing in the morning weekly or more often. In two-third others had been concerned about the drinking. Users of cannabis had a higher AUDIT score, while gambling was unassociated to alcohol use. Substantial gender and regional differences were seen. DISCUSSION: The AUDIT screening was found useful in individual and national treatment planning. Data suggested that particular focus should be given to women in treatment, and the service offered to the East Greenlandic population.

Sustainable weight loss over three years in children with obesity: a pragmatic family-centered lifestyle intervention.

INTRODUCTION: Childhood obesity has psychological consequences and increases the risk of continuous obesity into adulthood, associated with development of non-communicable disease (e.g. type 2 diabetes). Short-term weight loss intervention studies show good results but long-term studies are limited. METHODS: One hundred ninety-nine obese children (4-18 years of age), with a BMI-SDS (standard deviation score) above + 2 SDS were enrolled into a multifactorial family-centered lifestyle intervention study. The children had yearly visits in the outpatient clinic for anthropometrics, blood samples and DXA-scans, and 6-8 meeting with community health workers between these visits. The children followed the intervention up to 3 years. RESULTS: After a follow-up of 26.7 ± 17.5 months a reduction in BMI-SDS of - 0.25 SDS (p < 0.001) was observed. The 57 children who were adherent to the intervention for ≥ 2 years had significantly reduced BMI-SDS compared to the 142 children with shorter intervention (BMI-SDS: - 0.38 ± 0.67 vs. - 0.20 ± 0.50, p = 0.036). All weight loss was accompanied by decrease in fat mass and increase in muscle mass (p < 0.001). CONCLUSION: The intervention was found to induce long-term reduction in BMI-SDS in obese children, with beneficial change in body composition. Children who followed the intervention the longest had the greatest reduction in BMI-SDS. LEVEL OF EVIDENCE: Level III, longitudinal cohort study.

Uric Acid Is Elevated in Children With Obesity and Decreases After Weight Loss.

Introduction: Childhood obesity is an increasing condition associated with continuous obesity into adulthood and development of comorbidities. Adult studies show an association between serum uric acid (SUA) levels and body mass index (BMI). The aim of this retro perspective exploratory study was to investigate SUA in obese children and adolescents and the effects of a subsequent weight reduction. Materials and Methods: One hundred and seventy-one children (age 4-18), with obesity (i.e. BMI-SDS of +2 or higher) were included in a multifactorial lifestyle intervention. The children participating were annually measured for anthropometrics, blood samples and DEXA-scans for up to 3 years. Eighty-nine children were included for follow-up analysis. Results: After a follow-up of 20.7 ± 9.4 months a reduction in BMI-SDS of -0.34 ± 0.53 (p < 0.01) was observed. SUA was found to be positively associated with changes in BMI-SDS. SUA levels decreased in the 65 children who lost weight during the trial, conversely, SUA increased in the 23 children who gained weight during the trial (p < 0.01 between groups). Conclusion: SUA was found to correlate with measures of obesity and for the first time, this intervention demonstrates a positive relationship between SUA and weight reduction in children with obesity.

Does establishing local treatment institutions lead to different populations seeking treatment among Greenlandic Inuit?

Introduction: In 2016, a new addiction treatment service was established in Greenland to tackle the addiction problems with alcohol, cannabis and gambling among the population. The new service has established a treatment center in each of the five municipalities and works in partnership with a central private provider of treatment for those who reside in areas without a local treatment center.Methods: The national addiction database provided us with data from the Alcohol Use Disorder Identification Test, Alcohol Severity Index and questions on cannabis use and gambling behavior received at referral to, and at initiation of treatment. The data were analyzed for differences between the population in local or central treatment using SPSS version 25 (SPSS Inc., Chicago, IL).Results: Significant differences between the individuals in local and central treatment were revealed. Individuals in local treatment are more often women with minor children and a job, and their alcohol use is concentrated on weekends/holidays. Individuals in central treatment are more equal in both genders, few have minor children living at home, heavy drinking is more pronounced, and cannabis is used more frequently as well.Discussion: The findings support our expectations of local treatment being more attractive to individuals with obligations at home. The differences in the populations are worth considering when planning the treatment service, as the needs of the populations might differ. The findings are limited by many missing in the analyses, which we believe is caused by the establishing process of the new service.

A Mobile Phone App Featuring Cue Exposure Therapy As Aftercare for Alcohol Use Disorders: An Investigator-Blinded Randomized Controlled Trial.

BACKGROUND: Cue exposure therapy (CET) is a psychological approach developed to prepare individuals with alcohol use disorder (AUD) for confronting alcohol and associated stimuli in real life. CET has shown promise when treating AUD in group sessions, but it is unknown whether progressing from group sessions to using a mobile phone app is an effective delivery pathway. OBJECTIVE: The objectives of this study were to investigate (1) whether CET as aftercare would increase the effectiveness of primary treatment with cognitive behavior therapy, and (2) whether CET delivered through a mobile phone app would be similarly effective to CET via group sessions. METHODS: A total of 164 individuals with AUD were randomized to one of three groups: CET as group aftercare (CET group), CET as fully automated mobile phone app aftercare (CET app), or aftercare as usual. Study outcomes were assessed face-to-face at preaftercare, postaftercare, and again at 6 months after aftercare treatment. Generalized mixed models were used to compare the trajectories of the groups over time on drinking, cravings, and use of urge-specific coping skills (USCS). RESULTS: In all, 153 of 164 individuals (93%) completed assessments both at posttreatment and 6-month follow-up assessments. No differences in the trajectories of predicted means were found between the experimental groups (CET group and app) compared with aftercare as usual on drinking and craving outcomes over time. Both CET group (predicted mean difference 5.99, SE 2.59, z=2.31, P=.02) and the CET app (predicted mean difference 4.90, SE 2.26, z=2.31, P=.02) showed increased use of USCS compared to aftercare as usual at posttreatment, but this effect was reduced at the 6-month follow-up. No differences were detected between the two experimental CET groups on any outcomes. CONCLUSIONS: CET with USCS delivered as aftercare either via group sessions or a mobile phone app did not increase the effectiveness of primary treatment. This suggests that CET with USCS may not be an effective psychological approach for the aftercare of individuals treated for AUD.

Population genomics of an outbreak of the potato late blight pathogen, Phytophthora infestans, reveals both clonality and high genotypic diversity.

An outbreak of the potato late blight pathogen Phytophthora infestans in Denmark was characterized in order to resolve the population structure and determine to what extent sexual reproduction was occurring. A standard set of microsatellite simple sequence repeats (SSRs) and single nucleotide polymorphism (SNP) markers generated using restriction site-associated DNA sequencing (RAD-seq) were employed in parallel. A total of 83 individuals, isolated from seven different potato fields in 2014, were analysed together with five Danish whole-genome sequenced isolates, as well as two Mexican individuals used as an outgroup. From a filtered dataset of 55 288 SNPs, population genomics analyses revealed no sign of recombination, implying clonality. In spite of this, multilocus genotypes were unique to individual potato fields, with little evidence of gene flow between fields. Ploidy analysis performed on the SNPs dataset indicated that the majority of isolates were diploid. These contradictory results with clonality and high genotypic diversity may suggest that rare sexual events likely still contribute to the population. Comparison of the results generated by SSRs vs SNPs data indicated that large marker sets, generated by RAD-seq, may be advised going forward, as it provides a higher level of genetic discrimination than SSRs.

Making a bridge between general hospital and specialised community-based treatment for alcohol use disorder-A pragmatic randomised controlled trial.

AIM: To investigate if more patients in the intervention group attended specialized alcohol treatment compared with a treatment-as-usual group (TAU). METHODS: Pragmatic randomized controlled trial where consecutive patients, admitted to somatic hospitals, filled out a lifestyle questionnaire with the Alcohol Use Disorder Identification Test (AUDIT) embedded. Patients scoring 8+ on AUDIT were included in the study. Included patients were randomized to either a Danish screening brief intervention and referral to treatment (SBIRT) called the Relay model or TAU depending on date of admission. The Relay group was offered a brief alcohol intervention by an outreach alcohol therapist. Patients scoring 16 points and above on the AUDIT test also received referral to alcohol treatment. Outcome was attendance at specialized outpatient alcohol treatment centres after discharge from hospital. Information on patients was gathered from municipal databases at 18 months follow-up. RESULTS: A total of 3534 patients completed the questionnaire, and 609 patients (17%) scored AUDIT 8+. 48 patients were lost to follow-up, and the final sample had 561 patients. Only 33 patients (6%) attended outpatient treatment at 18-months follow-up, but significantly more patients in the Relay group sought alcohol treatment than in the TAU group (OR = 2.5 [1.2;5.2] (p = 0.017)). Number needed to treat (NNT) was 20 [95% CI 11.2;112.3]. CONCLUSION: The Relay intervention was associated with more patients attending specialized treatment, but further research is needed to establish if general hospitals are an excellent platform for performing SBIRT.

The influence of timing the application of nitrogen fertilizer on early blight (Alternaria solani).

BACKGROUND: Field experiments were carried out in 2016 and 2017 to study the influence of timing the application of nitrogen fertilizer (N-fertilizer) on the susceptibility of potatoes to early blight. We hypothesized that potatoes that receive N-fertilizer as split applications or a one-time application at emergence will have a higher N content and be less susceptible to early blight than those that receive N-fertilizer as a one-time application before planting. N-fertilizer was applied either as a one-time application before planting or at emergence and as split applications. RESULTS: Potatoes that did not receive N-fertilizer were more susceptible to early blight [high area under the disease progress curve (AUDPC)] than those that did receive N-fertilizer (low AUDPC). The timing of N-fertilizer application had a significant effect on the susceptibility of potatoes to early blight. Potatoes that received the entire quantity of N-fertilizer at emergence or as split applications had higher N contents and were less susceptible to early blight than those that received the entire quantity of N-fertilizer before planting. Potatoes that did not receive N-fertilizer had a markedly lower starch yield than potatoes that received N-fertilizer. Potatoes that received the entire quantity of N-fertilizer before planting had a lower starch yield than potatoes that received the entire quantity of N-fertilizer at emergence or as split applications. CONCLUSION: N-fertilizer applied as a one-time application at emergence or as a split application was the best treatment to ensure both high N content and lower attack of early blight, which confirms our hypothesis. © 2018 Society of Chemical Industry.
