Systemic antibiotics for Pseudomonas aeruginosa infection in outpatients with non-hospitalised exacerbations of pre-existing lung diseases: a randomised clinical trial.

BACKGROUND: The effect of dual systemic antibiotic therapy against Pseudomonas aeruginosa in patients with pre-existing lung disease is unknown. To assess whether dual systemic antibiotics against P. aeruginosa in outpatients with COPD, non-cystic fibrosis (non-CF) bronchiectasis, or asthma can improve outcomes. METHODS: Multicenter, randomised, open-label trial conducted at seven respiratory outpatient clinics in Denmark. Outpatients with COPD, non-CF bronchiectasis, or asthma with a current P. aeruginosa-positive lower respiratory tract culture (clinical routine samples obtained based on symptoms of exacerbation not requiring hospitalisation), regardless of prior P. aeruginosa-status, no current need for hospitalisation, and at least two moderate or one hospitalisation-requiring exacerbation within the last year were eligible. Patients were assigned 1:1 to 14 days of dual systemic anti-pseudomonal antibiotics or no antibiotic treatment. Primary outcome was time to prednisolone or antibiotic-requiring exacerbation or death from day 20 to day 365. RESULTS: The trial was stopped prematurely based in lack of recruitment during the COVID-19 pandemic, this decision was endorsed by the Data and Safety Monitoring Board. Forty-nine outpatients were included in the study. There was a reduction in risk of the primary outcome in the antibiotic group compared to the control group (HR 0.51 (95%CI 0.27-0.96), p = 0.037). The incidence of admissions with exacerbation within one year was 1.1 (95%CI 0.6-1.7) in the dual antibiotic group vs. 2.9 (95%CI 1.3-4.5) in the control group, p = 0.037. CONCLUSIONS: Use of dual systemic antibiotics for 14 days against P. aeruginosa in outpatients with chronic lung diseases and no judged need for hospitalisation, improved clinical outcomes markedly. The main limitation was the premature closure of the trial. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03262142, registration date 2017-08-25.

High-intensity training in patients with lacunar stroke: A one-year follow-up.

OBJECTIVES: Physical inactivity is a major risk factor for stroke. It is a challenge for patients to initiate and adhere to regular exercise post-stroke. Early initiation of home-based high-intensity interval training (HIIT) may engage patients in physical activity, improve cardiorespiratory fitness, and reduce risk of recurrent stroke. MATERIALS AND METHODS: Post-intervention follow-up of patients with lacunar stroke, randomized to three-months HIIT including weekly motivational calls, or usual care. At follow-up (six- and 12-months post-stroke), we investigated changes in cardiorespiratory fitness, physical activity, fatigue, depression, mental well-being, stress, cognition, cardiovascular function, and recurrent stroke. RESULTS: We included 71 patients of whom 59 patients (mean age: 63.9 ± 8.8 years) completed six- and 12-month follow-up. No change was detected in cardiorespiratory fitness between groups from baseline to 12-months follow-up. At six months, vigorous-intensity activity (median hours/week [interquartile range]) was maintained in the intervention group (baseline, 0[0;2]; post-intervention, 2[0;3]; six-month, 2[0;4]) and increased in the usual care group (baseline, 0[0;1]; post-intervention, 1[0;2]; six-month, 1[0;3]), with no difference between groups. Vigorous-intensity activity declined to baseline levels at 12-months in both groups. Secondary outcomes improved from baseline to 12-months with no significant differences between groups. Similar rate of recurrent stroke (n=3) occurred in each group with a three-month delay in the intervention group. CONCLUSIONS: Early initiated HIIT did not increase long-term cardiorespiratory fitness, but increased time spent doing vigorous-intensity activities post-stroke. Decline to baseline activity level at 12 months warrants identification of motivators to initiate and sustain physical activity post-stroke.

Azithromycin and hydroxychloroquine in hospitalised patients with confirmed COVID-19: a randomised double-blinded placebo-controlled trial.

BACKGROUND: Combining the antibiotic azithromycin and hydroxychloroquine induces airway immunomodulatory effects, with the latter also having in vitro antiviral properties. This may improve outcomes in patients hospitalised for coronavirus disease 2019 (COVID-19). METHODS: Placebo-controlled double-blind randomised multicentre trial. Patients aged ≥18 years, admitted to hospital for ≤48 h (not intensive care) with a positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reverse transcription PCR test were recruited. The intervention was 500 mg daily azithromycin for 3 days followed by 250 mg daily azithromycin for 12 days combined with 200 mg twice-daily hydroxychloroquine for all 15 days. The control group received placebo/placebo. The primary outcome was days alive and discharged from hospital within 14 days (DAOH14). RESULTS: After randomisation of 117 patients, at the first planned interim analysis, the data and safety monitoring board recommended stopping enrolment due to futility, based on pre-specified criteria. Consequently, the trial was terminated on 1 February 2021. 61 patients received the combined intervention and 56 patients received placebo. In the intervention group, patients had a median (interquartile range) 9.0 (3-11) DAOH14 versus 9.0 (7-10) DAOH14 in the placebo group (p=0.90). The primary safety outcome, death from all causes on day 30, occurred for one patient in the intervention group versus two patients receiving placebo (p=0.52), and readmittance or death within 30 days occurred for nine patients in the intervention group versus six patients receiving placebo (p=0.57). CONCLUSIONS: The combination of azithromycin and hydroxychloroquine did not improve survival or length of hospitalisation in patients with COVID-19.

Carfilzomib and dexamethasone maintenance following salvage ASCT in multiple myeloma: A randomised phase 2 trial by the Nordic Myeloma Study Group.

OBJECTIVE: We investigated the efficacy and safety of carfilzomib-containing induction before salvage high-dose melphalan with autologous stem-cell transplantation (salvage ASCT) and maintenance with carfilzomib and dexamethasone after salvage ASCT in multiple myeloma. METHODS: This randomised, open-label, phase 2 trial included patients with first relapse of multiple myeloma after upfront ASCT who were re-induced with four cycles of carfilzomib, cyclophosphamide and dexamethasone. Two months after salvage, ASCT patients were randomised to either observation or maintenance therapy with iv carfilzomib 27 â†’ 56 mg/sqm and p.o. dexamethasone 20 mg every second week. The study enrolled 200 patients of which 168 were randomised to either maintenance with carfilzomib and dexamethasone (n = 82) or observation (n = 86). RESULTS: Median time to progression (TTP) after randomisation was 25.1 months (22.5-NR) in the carfilzomib-dexamethasone maintenance group and 16.7 months (14.4-21.8) in the control group (HR 0.46, 95% CI 0.30-0.71; P = .0004). The most common adverse events during maintenance were thrombocytopenia, anaemia, hypertension, dyspnoea and bacterial infections. CONCLUSION: In summary, maintenance therapy with carfilzomib and dexamethasone after salvage ASCT prolonged TTP with 8 months. The maintenance treatment was in general well-tolerated with manageable toxicity.

Physical activity after colorectal cancer surgery-a cross sectional study of patients with a long-term stoma.

PURPOSE: Physical activity is recommended to cancer survivors by the World Health Organisation (WHO) and is associated with improved survival after colorectal cancer. It remains unclear whether having a stoma is a barrier for an active lifestyle. We examined the level of physical activity and explored factors impacting physical activity in survivors with a stoma. METHODS: A total of 1265 (65%) patients in the Danish Stoma Database completed a multidimensional survey. Physical activity of moderate- and vigorous-intensity was assessed using two validated questions. Based on WHO guidelines, physical activity was categorised into 'Meeting' or 'Not Meeting' recommendations. Multivariate regression analysis, adjusting for potential confounders, provided odds ratio (OR) and 95% confidence intervals (CI) for factors' association with'Not Meeting' guideline recommendations. RESULTS: In total, 571 patients with colorectal cancer reported on physical activity at a median of 4.3 years (interquartile range 3.1-5.8) after stoma surgery. Two hundred ninety-three patients (51%) were 'Meeting recommendations' and 63% of them were 'Highly active'. Two hundred seventy-eight were 'Not meeting' recommendations (49%). Of the factors analysed, patients without support garment were more likely (OR 1.72 [95% CI 1.16; 2.54] not to meet guideline recommendations. We found no association between stoma type, surgical procedure, parastomal bulging and 'problematic stoma' and level of physical activity, respectively. CONCLUSION: In this large sample of survivors with a stoma half of patients met or exceeded guideline recommendations. Of patients not meeting recommendations some could potentially meet the recommendations by modest increases in either moderate or vigorous activity.

Impact of a Parastomal Bulge on Quality of Life - A Cross-sectional Study of Patients From the Danish Stoma Database.

OBJECTIVE: To investigate stoma specific and generic HRQoL in patients with and without a parastomal bulge. BACKGROUND: Most patients have to live with their stoma complicated by a parastomal bulge. How this affects quality of life remains unclear. METHODS: Patients in the Danish Stoma Database completed the Short-form 36 health survey and the stoma-QOL questionnaire. Linear regression analysis, adjusted for potential confounding factors, provided mean and mean score differences and 95% confidence intervals for each HRQoL scale and item. Cohens d provided estimates of effect size. RESULTS: A total of 1265 patients (65%) completed the questionnaire 4.4 (interquartile range 3.1-6.0) years after stoma surgery. Of these, 693 (55%) patients with a parastomal bulge had significantly impaired (P < 0.01) HRQoL across all stoma specific and generic health domains compared to patients without a parastomal bulge. In patients with a benign diagnosis or an ileostomy, a parastomal bulge impacted significantly on Social Functioning and Mental Health resulting in a worse Mental Component Summary. A large bulge >10 cm impaired HRQoL (P < 0.01) across all stoma specific and generic domains. The impact on HRQoL was independent of time with the bulge. CONCLUSIONS: A novel finding in this large, unselected sample from high-quality regional registries was that parastomal bulging was associated with substantial and sustained impairment of HRQoL.

Outcome of treatment with carfilzomib before and after treatment with daratumumab in relapsed or refractory multiple myeloma patients.

Real world evidence is important since most patients cannot be included in randomized clinical trials (RCTs). In a nationwide, cohort of relapsed/refractory multiple myeloma patients treated with daratumumab (N = 635), we retrospective studied patients treated with carfilzomib (N = 251). Data were collected by audit of medical records. We compared characteristics of patients treated with carfilzomib before daratumumab (Car-Da; N = 150) and after daratumumab (Da-Car; N = 101) with those not treated with carfilzomib (N = 384). Furthermore, we examined effectiveness and safety of carfilzomib. The group of patients treated with carfilzomib differed from patients not treated with carfilzomib in the following parameters: They were younger, more were treated up-front with high dose melphalan and autologous stem cell transplantation (HDM-ASCT)and had relapse within 18 months thereafter, and more had high-risk cytogenetic abnormalities (CA) and amplification 1q (amp1q). In patients treated with Car-Da, 30.3% had high-risk CA and 30.1% had amp1q and in Da-Car it was 43.3% and 41%, respectively. In the Car-Da cohort, 34.4% experienced early relapse after HDM-ASCT versus 47.4% in the Da-Car cohort. The percentage of patients with very good partial remission was higher in patients treated with Car-Da compared to Da-Car (31.7% vs. 17.4%). The median duration of treatment and time to next treatment (TNT) of Car-Da/Da-Car were 4.6/4.3 months and 7.1/4.3 months and only a trend toward superior TNT for Car-Da was found (p = 0.06). Toxicity of carfilzomib was the same as reported in RCT. A similar poor TNT of daratumumab was found when used before (5.6 months) or after carfilzomib (4.9 months). In this cohort of patients with sequential treatment with carfilzomib and daratumumab or vice versa, a high percentage of patients were high-risk by CA, amp1q, and early relapse after HDM-ASCT. Outcome of Car-DA and outcome of Da-Car were equally poor. These patients should be considered for new promising treatment strategies.

Clarithromycin added to bortezomib-cyclophosphamide-dexamethasone impairs health-related quality of life in multiple myeloma patients.

OBJECTIVES: The Danish Myeloma Study Group initiated a randomized, placebo-controlled, double-blinded phase II study to investigate the efficacy of adding clarithromycin to cyclophosphamide-bortezomib-dexamethasone (VCD) induction therapy in transplant eligible, newly diagnosed multiple myeloma patients. The study was prematurely terminated due to severe complications, and no effect of adding clarithromycin was found. The aim of this study was to compare health-related quality of life (HRQoL) between the two groups and to explore the coherence hereof with adverse event (AE) registration by clinicians. METHODS: Patients completed three validated HRQoL questionnaires at inclusion, before cyclophosphamide priming, and two months after high-dose therapy (HDT). The mean score difference was interpreted by clinically relevant differences between groups. Spearman's correlation analysis was used to compare patient-reported toxicities with AEs. RESULTS: Of 58 included patients, 55 participated in the HRQoL reporting. Before cyclophosphamide priming, patients in the clarithromycin group reported clinically relevant reduced HRQoL for eleven domains with persistent reduction in four domains two months after HDT. Poor correlation between patient-reported toxicities and clinician-reported AEs was observed. CONCLUSIONS: Despite the premature study termination, our data demonstrate impaired HRQoL when clarithromycin was added to the VCD regimen. We found clear underreporting of toxicities by clinicians. ClinicalTrials.gov number NCT02573935.

Stratification by MYC expression has prognostic impact in MYC translocated B-cell lymphoma-Identifies a subgroup of patients with poor outcome.

OBJECTIVE: In patients with large B-cell lymphoma (LBCL) according to WHO, the prognostic significance of MYC translocation is still not sufficiently clarified. We therefore aimed to investigate whether prognostication could be improved in patients with MYC translocation positive LBCL by additional stratification according to MYC and BCL2 protein expression levels or MYC translocation partner gene as well as concurrent BCL2 and/or BCL6 translocation (DH). METHODS: From an unselected consecutive cohort of >600 patients with LBCL investigated with fluorescent in situ hybridization (FISH), 64 patients were diagnosed with MYC translocation positive LBCL and included in the study. They were further investigated for supplemental translocations with FISH and MYC and BCL2 protein expression with immunohistochemistry (IHC). RESULTS: MYC expression >75% was associated with both reduced progression-free survival (PFS) and overall survival (OS) (PFS: HR 6.8 (95% CI 1.5-31), P = 0.004. OS: HR 4.3 (95% CI 0.9-21), P = 0.05). Immunoglobulin (IG) MYC translocation partner gene was related to high MYC protein expression (P = 0.047) but was not prognostic for PFS (P = 0.8) or OS (P = 0.6). DH did not confer a worse outcome compared to MYC single hit (SH). These findings were confirmed in a comparable, independent validation cohort of 28 patients with MYC translocation positive LBCL. All patients included in the survival analyses were treated with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) or R-CHOEP (R-CHOP + etoposide). CONCLUSION: These findings suggest that in patients with LBCL stratification by MYC protein expression level significantly improves the prognostic impact associated with MYC translocation.

68Ga-PSMA-PET/CT in comparison with 18F-fluoride-PET/CT and whole-body MRI for the detection of bone metastases in patients with prostate cancer: a prospective diagnostic accuracy study.

OBJECTIVES: To determine the diagnostic accuracy of 68gallium prostate-specific membrane antigen (PSMA)-based positron emission tomography/computed tomography (PET/CT) in comparison with 18F-fluoride-based PET/CT (NaF-PET/CT) and whole-body magnetic resonance imaging (WB-MRI) for the detection of bone metastases in patients with prostate cancer. METHODS: Sixty patients with prostate cancer were included in the period May 2016 to June 2017. The participants underwent three scans (index tests) within 30 days: a NaF-PET/CT, a WB-MRI and a PSMA-PET/CT. Experienced specialists assessed the scans. In the absence of a histological reference standard, the final diagnosis was determined as a panel diagnosis. Measures of the diagnostic performances of the index tests were calculated from patient-based dichotomous outcomes (0 or ≥ 1 bone metastasis) and pairwise compared (McNemar test). For each index test, the agreement with the final diagnosis with regard to the number of bone metastases detected (0, 1-5, > 5) and the inter-reader agreement was calculated (kappa coefficients). RESULTS: Fifty-five patients constituted the final study population; 20 patients (36%) were classified as having bone metastatic disease as their final diagnosis. The patient-based diagnostic performances were (sensitivity, specificity, overall accuracy) PSMA-PET/CT (100%, 100%, 100%), NaF-PET/CT (95%, 97%, 96%) and WB-MRI (80%, 83%, 82%). The overall accuracy of PSMA-PET/CT was significantly more favourable compared to WB-MRI (p = 0.004), but not to NaF-PET/CT (p = 0.48). PSMA-PET/CT classified the number of bone metastases reliably compared to the final diagnosis (kappa coefficient 0.97) and with an "almost perfect" inter-reader agreement (kappa coefficient 0.93). CONCLUSIONS: The overall accuracy of PSMA-PET/CT was significantly more advantageous compared to WB-MRI, but not to NaF-PET/CT. KEY POINTS: • PSMA-PET/CT assessed the presence of bone metastases correctly in all 55 patients • PSMA-PET/CT was more advantageous compared to WB-MRI • No difference was found between PSMA-PET/CT and NaF-PET/CT.

Dynamic contrast-enhanced EUS for quantification of tumor perfusion in colonic cancer: a prospective cohort study.

BACKGROUND AND AIMS: Dynamic contrast-enhanced EUS (CE-EUS) for quantification of perfusion in colonic tumors has not previously been reported in the literature. The aim of this study was to investigate correlations between perfusion parameters and vessel density assessed by immunohistochemical staining with antibodies toward CD31 and CD105. METHODS: We conducted a prospective clinical study of 28 patients with left-sided colonic adenocarcinoma who underwent CE-EUS and left-sided hemicolectomy within 2 weeks. CE-EUS recordings were analyzed in 2 regions of interest: the entire tumor and the most enhanced area. Immunohistochemical staining with CD31 and CD105 was performed on tumor tissue sections. The slides were manually scanned for highly vascularized areas, and counting of vessels was performed in hotspots within the tumor and invasive front. New vasculature was assessed by CD105. Associations between CE-EUS and CD31 and CD105 were investigated using Spearman correlation. RESULTS: We found significant P values for the correlation between CD31 and rise time (rho = .603 [95% confidence interval (95% CI), .238-.816]; P = .001) in tumor tissue and for the correlation between CD31 and rise time (rho = .50 [95% CI, .201-.695]; P = .008) and fall time (rho = .52 [95% CI, .204-.723]; P = .006) corresponding to the invasive front. We found no correlations between perfusion values evaluated by CE-EUS and CD105. CONCLUSIONS: Our results show a significant correlation for vessel density evaluated by CD31 and perfusion parameters evaluated by CE-EUS. This may be the first step toward using real-time CE-EUS for monitoring antiangiogenic therapies in colonic cancer. (Clinical trial registration number: NCT02324023.).

The Effect of a Home Delivery Meal Service of Energy- and Protein-Rich Meals on Quality of Life in Malnourished Outpatients Suffering from Lung Cancer: A Randomized Controlled Trial.

Undernutrition is prevalent in cancer patients and associated with increased incidence of complications and mortality. We investigated the effects of a home delivery meal service, providing a selection of energy-dense, protein-rich meals, on quality of life (QoL) in malnourished lung cancer patients. Forty lung cancer patients with nutritional risk score ≥3 (NRS-2002) were randomized to control or intervention. The intervention group was offered energy- and protein-rich main meals and snacks, delivered 3 times per week. The control group continued their habitual diet. Primary endpoint, QoL, and secondary endpoints were assessed at baseline, and after 6 and 12 wk. Data on unplanned readmissions, length of hospital stay, and mortality were collected 3 and 6 mo post-intervention. Intervention group improved standard Chair Stand Test (30-s CST) after 6 and 12 wk (P < 0.01) compared to control. Intervention exerted a significant positive effect on performance score after 12 wk (P  =  0.047). Increased energy and protein intakes were strongly associated with improved QoL, functional score, hand grip strength, symptom and performance scores. Food delivery service with energy- and protein-rich main meals and snacks can improve lower body strength and performance status in malnourished lung cancer patients.

Confocal laser endomicroscopy in ulcerative colitis: a longitudinal study of endomicroscopic changes and response to medical therapy (with videos).

BACKGROUND AND AIMS: Confocal laser endomicroscopy enables real-time in vivo microscopy during endoscopy and can predict relapse in patients with inflammatory bowel disease in remission. However, little is known about how endomicroscopic features change with time. The aim of this longitudinal study was to correlate colonic confocal laser endomicroscopy (CLE) in ulcerative colitis with histopathology and macroscopic appearance before and after intensification of medical treatment. METHODS: Twenty-two patients with ulcerative colitis in clinical relapse and 7 control subjects referred for colonoscopy were enrolled. The colonic mucosa was examined with high-definition colonoscopy, histopathology, and CLE at 4 colonic sites. Subsequently, patients requiring medical treatment escalation were referred for repeat endoscopy with CLE after 6 to 8 weeks. RESULTS: The baseline frequency of fluorescein leakage (P < .001), microerosions (P < .001), tortuosity of the crypts (P = .001), distortion of the crypts openings (P = .001), presence of inflammatory infiltrates (P < .001), and decreased crypt density (P < .001) were significantly higher in active ulcerative colitis compared with inactive ulcerative colitis and control subjects. A decrease in histopathologic score after medical treatment escalation was correlated with improvement in crypt tortuosity (rs = .35, P = .016), distortion of crypt openings (rs = .30, P = .045), and decreased crypt density (rs = .33, P = .026) but not in other features. CONCLUSIONS: CLE is an emerging endoscopic technique that reproducibly identifies mucosal changes in ulcerative colitis. With the exception of crypt changes, endomicroscopic features appear to improve slowly with time after medical treatment. ( CLINICAL TRIAL REGISTRATION NUMBER: NCT01684514.).

Confocal laser endomicroscopy: a novel method for prediction of relapse in Crohn's disease.

BACKGROUND AND STUDY AIMS: Confocal laser endomicroscopy (CLE) has been shown to predict relapse in ulcerative colitis in remission, but little is currently known about its role in Crohn's disease. The aim of this study was to identify reproducible CLE features in patients with Crohn's disease and to examine whether these are risk factors for relapse. PATIENTS AND METHODS: This was a single-center prospective feasibility study of CLE imaging in patients with Crohn's disease. CLE imaging was performed in the terminal ileum and four colorectal sites, and was correlated with histopathology and macroscopic appearance. Clinical relapse, defined as the need for treatment escalation or surgical intervention, was recorded during follow-up. RESULTS: The study included 50 patients: 39 with Crohn's disease (20 in remission), and 11 controls. Ileal fluorescein leakage and microerosions were significantly more frequent in patients with endoscopically active Crohn's disease compared with patients with inactive Crohn's disease and controls (P = 0.005 and (P = 0.006, respectively). The same applied to colorectal fluorescein leakage and vascular alterations ((P = 0.043 and (P = 0.034, respectively). During a 12-month follow-up period, ileal fluorescein leakage and microerosions were significant risk factors for relapse in the subgroup of patients in remission (log rank (P = 0.009 and (P = 0.007, respectively) as well as in the entire group of patients with Crohn's disease (log rank (P = 0.006 and (P = 0.01, respectively). Inter- and intraobserver reproducibility was almost perfect (κ > 0.80) or substantial (κ > 0.60) for the majority of CLE parameters. CONCLUSIONS: CLE can identify reproducible microscopic changes in the terminal ileum that are risk factors for relapse in patients with otherwise inactive Crohn's disease.

Toxicity profile and treatment delays in NOPHO ALL2008-comparing adults and children with Philadelphia chromosome-negative acute lymphoblastic leukemia.

OBJECTIVES: Cure rates improve when adolescents and young adults with acute lymphoblastic leukemia (ALL) are treated according to pediatric protocols. Assumed risks of toxicities and associated delays in treatment have played a role in setting upper age limits. The aim of this study was to examine the toxicity profile and treatment delays in NOPHO ALL2008 comparing children and adults. METHODS: We collected information on 19 treatment-related toxicities, systematically captured at 3-month intervals throughout therapy, and time intervals between 12 consecutive treatment phases for 1076 patients aged 1-45 yrs treated according to the Nordic/Baltic ALL2008 protocol. RESULTS: No adults died during induction. The duration of induction therapy and postinduction treatment phases did not differ between children and adults, except for patients 18-45 yrs being significantly delayed during two of nine high-risk blocks (median number of days for patients 1-9, 10-17, and 18-45 yrs; the glucocorticosteroid/antimetabolite-based block B1: 24, 26, and 29 d, respectively, P = 0.001, and Block 5 (in most cases also a B block): 29, 29, and 37 d, respectively, P = 0.02). A higher incidence of thrombosis with increasing age was found; highest odds ratio 5.4 (95% CI: (2.6;11.0)) for patients 15-17 yrs compared with children 1-9 yrs (P < 0.0001). Risk of avascular osteonecrosis was related to age with the highest OR for patients 10-14 yrs (OR = 10.4 (95% CI: (4.4;24.9)), P < 0.0001). CONCLUSION: Adults followed and tolerated the NOPHO ALL2008 protocol virtually as well as children, although thrombosis and avascular osteonecrosis was most common among adolescents.

Preferred Presentation of the Visual Analog Scale for Measurement of Postoperative Pain.

BACKGROUND: The aim of this study was to evaluate differences in pain scores with different visual analog scale (VAS) presentations and to compare those differences with a numeric rating scale. We also asked the patients for preference of the different methods. METHODS: Prior to the trial, we performed power calculations to estimate a preferred sample size, and 62 postoperative patients supplied a complete set of data to the study. Inclusion criteria were newly operated patients within the first 5 days after surgery. Every patient included was with 1-minute intervals and presented with one of the following 100-mm VAS lines: VAS horizontal with or without stop lines at the endings, or VAS vertical with or without stop lines. They also completed a numeric rating scale (NRS). RESULTS: We did not find differences in pain scores between the four VAS measures. The NRS had slightly higher pain scores than VAS, especially at low levels of pain. Patients preferred the NRS as compared to the VAS, and when choosing between the four different VAS presentations, they preferred the horizontal VAS with stop lines at the ends. CONCLUSION: For daily clinical practice for guiding postoperative analgesic treatment, the NRS seems to be a good option measuring pain reliably with good patient understanding and acceptance. For pain research, where there may be more time to explain the method and when a scale with more data points may be preferred, a VAS horizontal including stop lines at the ends can be recommended.

The influence of diabetes mellitus on midregional proadrenomedullin concentrations and prognostic value in heart failure outpatients.

BACKGROUND: Diabetes mellitus (DM) is associated with an adverse outcome in heart failure (HF). Increased concentrations of midregional proadrenomedullin (MR-proADM) have been associated with DM and are predictors of mortality in HF patients. The aim of this study was to elucidate the impact of DM on MR-proADM concentrations and the prognostic value regarding all-cause mortality and hospitalization among HF patients. METHODS AND RESULTS: We included 366 patients from an HF clinic; 69 (19%) had a history of DM and 40 (11%) had newly diagnosed DM (HbA1c ≥48 mmol/mol). The median MR-proADM concentration was unaffected by DM status (P = .20) but increased in HF patients with impaired renal function (P < .001). During a median follow-up of 55 months, 189 died, and 292 either died or were hospitalized. After adjustment for clinically relevant parameters, MR-proADM was associated with all-cause mortality (hazard ratio [HR] 1.3, 95% confidence interval [CI] 1.1-1.4; P = .01) and the combined end point of death and hospitalization (HR 1.2, 95% CI 1.1-1.4; P = .02) per 1 SD increment of ln-transformed variable. No interaction between DM and MR-proADM was found regarding mortality or hospitalization. CONCLUSIONS: Diabetes status had no impact on MR-proADM concentrations or in the predictive ability of MR-proADM in HF patients.

Rituximab and dexamethasone vs dexamethasone monotherapy in newly diagnosed patients with primary immune thrombocytopenia.

In this study, we report the results from the largest cohort to date of newly diagnosed adult immune thrombocytopenia patients randomized to treatment with dexamethasone alone or in combination with rituximab. Eligible were patients with platelet counts ≤25×10(9)/L or ≤50×10(9)/L with bleeding symptoms. A total of 133 patients were randomly assigned to either dexamethasone 40 mg/day for 4 days (n = 71) or in combination with rituximab 375 mg/m(2) weekly for 4 weeks (n = 62). Patients were allowed supplemental dexamethasone every 1 to 4 weeks for up to 6 cycles. Our primary end point, sustained response (ie, platelets ≥50×10(9)/L) at 6 months follow-up, was reached in 58% of patients in the rituximab + dexamethasone group vs 37% in the dexamethasone group (P = .02). The median follow-up time was 922 days. We found longer time to relapse (P = .03) and longer time to rescue treatment (P = .007) in the rituximab + dexamethasone group. There was an increased incidence of grade 3 to 4 adverse events in the rituximab + dexamethasone group (P = .04). In conclusion, rituximab + dexamethasone induced higher response rates and longer time to relapse than dexamethasone alone. This study is registered at http://clinicaltrials.gov as NCT00909077.

Prevalence of glucose-6-phosphate dehydrogenase deficiency and diagnostic challenges in 1500 immigrants in Denmark examined for haemoglobinopathies.

Similar to the thalassaemia syndromes, glucose-6-phosphate dehydrogenase (G6PD) deficiency is highly prevalent in areas historically exposed to malaria. In the present study, we used quantitative and molecular methods to determine the prevalence of G6PD deficiency in a population of 1508 immigrants in Denmark. We found the allele frequency to be between 2.4 and 2.9% in the female immigrants. Furthermore, the mutation pattern in the studied population showed a high prevalence of the G6PD A-(202A) variant in African and African-American immigrants, a high prevalence of the G6PD Mediterranean variant in Mediterranean European and Western Asian immigrants, and substantial heterogeneity in the variants found in the Eastern Asian/Pacific immigrants. Inasmuch as many of the patients included in this investigation had various thalassaemic syndromes, we were able to evaluate the effects of the interaction between a low mean corpuscular haemoglobin (MCH) value and G6PD activity, particularly in heterozygous females. The activity level was markedly influenced by the MCH value in females with normal G6PD activity, but not in heterozygous and homozygous females. Comparison of patients with normal G6PD activity and heterozygous females indicated considerable overlap in activity levels. To help separating heterozygous females from females with wild-type genes, a DNA analysis is necessary when the female activity level is between 4.0 and 4.9 U/g hgb corresponding to 50-60% of the median activity of unaffected males.
