Modified-release nicotinamide for the treatment of hyperphosphataemia in haemodialysis patients: 52-week efficacy and safety results of the phase 3 randomized controlled NOPHOS trial.

BACKGROUND: We previously reported that modified-release nicotinamide (NAMR) was superior to placebo in reducing serum phosphate concentrations over 12 weeks in a large cohort of haemodialysis patients with hyperphosphataemia. Here we report outcomes after 52 weeks of treatment. METHODS: NOPHOS was a phase 3, international, randomized, controlled, double-blind trial with a parallel group design. NAMR (250-1500 mg/day) was investigated in comparison to placebo as an add-on therapy to an individual therapy with approved phosphate binders. RESULTS: In the intention-to-treat population (NAMR: n = 539; placebo: n = 183), serum phosphate was significantly lower in the NAMR group compared with the placebo group at week 24 (5.40 ± 1.55 versus 5.79 ± 1.37 mg/dl, P < .001) with a mean difference of -0.39 mg/dl [95% confidence interval (CI) -0.66 to -0.13], but was comparable between the groups at week 52 [mean difference -0.08 (95% CI -0.36-0.20)]. In the completer population (n = 358), statistical significance in favour of NAMR was reached at weeks 24 and 52. The treatment effect was reduced in patients with high baseline serum intact parathyroid hormone (iPTH) compared with patients with low baseline serum iPTH. Compliant patients in the NAMR group had a more pronounced and sustained reduction in serum phosphate than non-compliant patients. NAMR treatment was associated with a significantly increased risk of thrombocytopenia, pruritus, anaemia, and diarrhoea. Herpes zoster occurred exclusively in patients randomized to NAMR. CONCLUSIONS: NAMR combined with phosphate binders significantly reduced serum phosphate over the first 24 weeks of treatment, but the treatment effect was not maintained up to week 52. Non-compliance may have contributed to reduced long-term efficacy. Several newly identified safety signals warrant further evaluation.

Five-Year Results of Coronary Artery Bypass Grafting With or Without Carotid Endarterectomy in Patients With Asymptomatic Carotid Artery Stenosis: CABACS RCT.

BACKGROUND: In patients with coronary artery disease and concomitant asymptomatic severe carotid stenosis, combined simultaneous coronary artery bypass grafting (CABG) and carotid endarterectomy (CEA) has been widely performed despite lack of evidence from randomized trials. We recently showed that the risk of stroke or death within 30 days was higher following CABG+CEA compared with CABG alone. Here, we report long-term outcomes following CABG with versus without CEA. METHODS: The CABACS (Coronary Artery Bypass Graft Surgery in Patients With Asymptomatic Carotid Stenosis Study) is a randomized, controlled, multicenter, open trial. Patients with asymptomatic severe (≥70%) carotid stenosis undergoing CABG were allocated either CABG+CEA or CABG alone, and follow-up was 5 years. Major secondary end points included nonfatal stroke or death, any death and any nonfatal stroke. Due to low recruitment, the study was stopped prematurely after randomization of 127 patients in 17 centers. RESULTS: By 5 years, the rate of stroke or death did not significantly differ between groups (CABG+CEA 40.6% [95% CI, 0.285-0.536], CABG alone 35.0% [95% CI, 0.231-0.484]; P=0.58). Higher albeit statistically nonsignificant rates of nonfatal strokes occurred at any time following CABG+CEA versus CABG alone (1 year: 19.3% versus 7.1%, P=0.09; 5 years: 29.4% versus 18.8%, P=0.25). All-cause mortality up to 5 years was similar in both groups (CABG+CEA: 25.4% versus CABG alone: 23.3%, hazard ratio, 1.148 [95% CI, 0.560-2.353]; P=0.71). Subgroup analyses did not reveal any significant effect of age, sex, preoperative modified Rankin Scale and center on outcome events. CONCLUSIONS: During 5-years follow-up, combined simultaneous CABG+CEA was associated with a higher albeit statistically nonsignificant rate of stroke or death compared with CABG alone. This was mainly due to a nonsignificantly higher perioperative risk following CABG+CEA. Since the power of our study was not sufficient, no significant effect of either procedure could be observed at any time during follow-up.

Methylphenidate treatment of adult ADHD patients improves the degree of ADHD severity under routine conditions.

Attention-deficit hyperactivity disorder (ADHD) is associated with substantial personal and social impairments. Besides psychosocial interventions, current guidelines recommend a therapy with methylphenidate (MPH). This prospective, non-interventional study aims to investigate the efficacy and tolerability of MPH treatment of adult ADHD patients in a real-world setting. 468 adult patients with newly diagnosed ADHD were observed for 12-14 weeks. Primary efficacy endpoint was the clinical global impression (CGI) by the physician. Secondary endpoints comprise patient evaluation (Wender-Reimherr self-report, WR-SR), safety, tolerability, and dosage of MPH. With a mean daily dose of 35.8 (±17.0) mg MPH, the population of patients being severely/most extremely ill or markedly ill decreased by 64% and 61%, respectively. According to physicians' assessment (CGI), 74.5% of patients were identified as treatment responders. The total score of patient-based assessment (WR-SR) improved by 23.5% (50.1 ± 40.3 points) with the most profound improvement in attention deficit (-30.0%), disorganization (-26.6%), and hyperactivity / unrest (-23.3%). Self-evaluation revealed a responder rate of 35.4%. In summary, MPH treatment improves the degree of ADHD severity under routine conditions. In addition, activities of daily living were facilitated when taking MPH. The rather poor responder rates determined by patient assessment as well as the comparatively low applied mean daily dose of 35.8 mg (median 40 mg) indicate sub-optimal dosing under routine conditions, not exploiting the full beneficial therapeutic potential of MPH.

Do adolescents with extreme obesity differ according to previous treatment seeking behavior? The Youth with Extreme obesity Study (YES) cohort.

OBJECTIVES: Adolescent extreme obesity is associated with somatic and psychiatric comorbidity, low quality of life, and social dysfunction. Nevertheless, few adolescents seek obesity treatment, thus many may elope appropriate care. We examine whether previous treatment seeking relates to disease burden, and whether previously non-treatment seeking adolescents accept diagnostic and therapeutic offers. This information is important to inform intervention strategies. METHODS: The Youth with Extreme obesity Study (YES) is a prospective, multicenter cohort study. We developed a novel recruitment strategy to span medical and vocational ascertainment settings and directly compare previously treatment seeking and non-treatment seeking youth. Participants aged 14-24 years; BMI ≥ 30 kg/m2 were enrolled at four medical- and one job centers. We present comorbidity and psycho-social baseline data by sex, obesity WHO grade I-III, and treatment-seeking status, defined as self-reported previous participation in a weight-loss program. RESULTS: Of 431 participants, 47% were male; mean age 16.6 (standard deviation 2.3) years, BMI 39.2 (7.5) kg/m2. Somatic comorbidity increased with obesity grade, p < 0.05: hypertension (42, 55, 64%), dyslipidemia (28, 24, 37%,), dysglycemia (9, 19, 20%,), elevated transaminases (15, 26, 30%). Quality of life (EQ5 D) decreased (74, 71, 70). Rates of psychiatric disorders were stable: depression 11%, attention deficit disorder 6%, substance use disorder 2%, self-injurious behavior 5%, suicide attempt 3%. Only 63% (56, 64, 69%) reported previous treatment seeking. Acceptance of the diagnostic (89%) or therapeutic (28%) program, medical or psychosocial situation did not differ by treatment seeking status. Acceptance of the therapeutic program was generally low, but high at the job center (92%). CONCLUSION: Irrespective of previous treatment seeking, adolescent extreme obesity was associated with high comorbidity and psychosocial burden. Acceptance of the diagnostic program overall and the therapeutic program at the job center were high. This underscores the need of innovative, accessible programs beyond the currently offered care.

Six versus eight doses of rituximab in patients with aggressive B cell lymphoma receiving six cycles of CHOP: results from the "Positron Emission Tomography-Guided Therapy of Aggressive Non-Hodgkin Lymphomas" (PETAL) trial.

Standard first-line treatment of aggressive B cell lymphoma comprises six or eight cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) plus eight doses of rituximab (R). Whether adding two doses of rituximab to six cycles of R-CHOP is of therapeutic benefit has not been systematically investigated. The Positron Emission Tomography-Guided Therapy of Aggressive Non-Hodgkin Lymphomas (PETAL) trial investigated the ability of [18F]-fluorodesoxyglucose PET scanning to guide treatment in aggressive non-Hodgkin lymphomas. Patients with B cell lymphomas and a negative interim scan received six cycles of R-CHOP with or without two extra doses of rituximab. For reasons related to trial design, only about a third underwent randomization between the two options. Combining randomized and non-randomized patients enabled subgroup analyses for diffuse large B cell lymphoma (DLBCL; n = 544), primary mediastinal B cell lymphoma (PMBCL; n = 37), and follicular lymphoma (FL) grade 3 (n = 35). With a median follow-up of 52 months, increasing the number of rituximab administrations failed to improve outcome. A non-significant trend for improved event-free survival was seen in DLBCL high-risk patients, as defined by the International Prognostic Index, while inferior survival was observed in female patients below the age of 60 years. Long-term outcome in PMBCL was excellent. Differences between FL grade 3a and FL grade 3b were not apparent. The results were confirmed in a Cox proportional hazard regression model and a propensity score matching analysis. In conclusion, adding two doses of rituximab to six cycles of R-CHOP did not improve outcome in patients with aggressive B cell lymphomas and a fast metabolic treatment response.

On estimands and the analysis of adverse events in the presence of varying follow-up times within the benefit assessment of therapies.

The analysis of adverse events (AEs) is a key component in the assessment of a drug's safety profile. Inappropriate analysis methods may result in misleading conclusions about a therapy's safety and consequently its benefit-risk ratio. The statistical analysis of AEs is complicated by the fact that the follow-up times can vary between the patients included in a clinical trial. This paper takes as its focus the analysis of AE data in the presence of varying follow-up times within the benefit assessment of therapeutic interventions. Instead of approaching this issue directly and solely from an analysis point of view, we first discuss what should be estimated in the context of safety data, leading to the concept of estimands. Although the current discussion on estimands is mainly related to efficacy evaluation, the concept is applicable to safety endpoints as well. Within the framework of estimands, we present statistical methods for analysing AEs with the focus being on the time to the occurrence of the first AE of a specific type. We give recommendations which estimators should be used for the estimands described. Furthermore, we state practical implications of the analysis of AEs in clinical trials and give an overview of examples across different indications. We also provide a review of current practices of health technology assessment (HTA) agencies with respect to the evaluation of safety data. Finally, we describe problems with meta-analyses of AE data and sketch possible solutions.

Safety of Simultaneous Coronary Artery Bypass Grafting and Carotid Endarterectomy Versus Isolated Coronary Artery Bypass Grafting: A Randomized Clinical Trial.

BACKGROUND AND PURPOSE: The optimal operative strategy in patients with severe carotid artery disease undergoing coronary artery bypass grafting (CABG) is unknown. We sought to investigate the safety and efficacy of synchronous combined carotid endarterectomy and CABG as compared with isolated CABG. METHODS: Patients with asymptomatic high-grade carotid artery stenosis ≥80% according to ECST (European Carotid Surgery Trial) ultrasound criteria (corresponding to ≥70% NASCET [North American Symptomatic Carotid Endarterectomy Trial]) who required CABG surgery were randomly assigned to synchronous carotid endarterectomy+CABG or isolated CABG. To avoid unbalanced prognostic factor distributions, randomization was stratified by center, age, sex, and modified Rankin Scale. The primary composite end point was the rate of stroke or death at 30 days. RESULTS: From 2010 to 2014, a total of 129 patients were enrolled at 17 centers in Germany and the Czech Republic. Because of withdrawal of funding after insufficient recruitment, enrolment was terminated early. At 30 days, the rate of any stroke or death in the intention-to-treat population was 12/65 (18.5%) in patients receiving synchronous carotid endarterectomy+CABG as compared with 6/62 (9.7%) in patients receiving isolated CABG (absolute risk reduction, 8.8%; 95% confidence interval, -3.2% to 20.8%; PWALD=0.12). Also for all secondary end points at 30 days and 1 year, there was no evidence for a significant treatment-group effect although patients undergoing isolated CABG tended to have better outcomes. CONCLUSIONS: Although our results cannot rule out a treatment-group effect because of lack of power, a superiority of the synchronous combined carotid endarterectomy+CABG approach seems unlikely. Five-year follow-up of patients is still ongoing. CLINICAL TRIAL REGISTRATION: URL: https://www.controlled-trials.com. Unique identifier: ISRCTN13486906.

A Randomized Trial of Daily Prednisone versus Pulsed Dexamethasone in Treatment-Naïve Adult Patients with Immune Thrombocytopenia: EIS 2002 Study.

Oral prednisone is considered the standard first-line therapy of adult immune thrombocytopenia, but its long-term efficacy is limited. We performed a prospective, randomized, multicenter trial comparing daily prednisone (1-2 mg/kg/day for 2-4 weeks with subsequent dose reduction) with six 3-week cycles of pulsed dexamethasone (0.6 mg/kg/day, days 1-4). The primary endpoint was remission duration. Of 26 patients enrolled, 22 were evaluable for response. Nine were treated with prednisone and 13 with dexamethasone. The median follow-up was 46 months. The initial response rate (PLT ≥50 × 109/l) was 100% in both groups. Long-term remissions were significantly more frequent with pulsed dexamethasone than with daily prednisone (12 months posttreatment: 77 vs. 22%; p = 0.027). The side effects were similar, but patients on dexamethasone suffered significantly more often from insomnia, while patients on prednisone tended to have more infectious complications. Although the cumulative cortisol equivalent dose was comparable during the first 4 weeks of therapy, it was significantly higher in the dexamethasone arm than in the prednisone arm during the ensuing treatment period. We conclude that repeated cycles of pulsed dexamethasone are a good alternative to daily prednisone as a first-line treatment of immune thrombocytopenia. The duration and intensity of glucocorticoid therapy are important determinants of treatment outcome.

Emotional and psychological safety in the context of digital transformation in healthcare: a mixed-method strategic foresight study.

BACKGROUND: Perceived safety has received attention in the digital transformation of healthcare. However, the impact of perceived safety on the future of digital transformation has not been fully elucidated. AIM: To investigate perceived safety in the context of the digital transformation of healthcare while considering relevant needs, influencing factors and impacts, including crisis events, to provide recommendations for action based on a participatory, multiperspective, strategic 5-year foresight viewpoint. METHODS: A strategic foresight study is conducted via a participatory mixed-methods design to understand the present related factors that are likely to be relevant to future developments in the digital transformation of healthcare. RESULTS: We observed that feeling safe plays a complex role in the digital transformation of healthcare. How perceived safety is considered has and will continue to impact the individual, organisational and system levels. Regarding a potential crisis event, controversial consequences have been observed. At its core, digital (health) literacy related to equity of access and human support is one of the crucial aspects in the context of perceived safety related to the successful implementation of digital technologies in healthcare. CONCLUSIONS: The scenarios showed that a continuation of the current situation over the next 5 years may result in partly desirable and partly undesirable outcomes. Concrete key factors should be used in practice to support both education and healthcare quality development and research. The essence of the scenarios should serve as a starting point for research agenda setting and political decision-making in the future. However, additional research is needed to quantify the correlations among the relevant factors.

Study protocol of Prednisone in episodic Cluster Headache (PredCH): a randomized, double-blind, placebo-controlled parallel group trial to evaluate the efficacy and safety of oral prednisone as an add-on therapy in the prophylactic treatment of episodic cluster headache with verapamil.

BACKGROUND: Episodic cluster headache (ECH) is a primary headache disorder that severely impairs patient's quality of life. First-line therapy in the initiation of a prophylactic treatment is verapamil. Due to its delayed onset of efficacy and the necessary slow titration of dosage for tolerability reasons prednisone is frequently added by clinicians to the initial prophylactic treatment of a cluster episode. This treatment strategy is thought to effectively reduce the number and intensity of cluster attacks in the beginning of a cluster episode (before verapamil is effective). This study will assess the efficacy and safety of oral prednisone as an add-on therapy to verapamil and compare it to a monotherapy with verapamil in the initial prophylactic treatment of a cluster episode. METHODS AND DESIGN: PredCH is a prospective, randomized, double-blind, placebo-controlled trial with parallel study arms. Eligible patients with episodic cluster headache will be randomized to a treatment intervention with prednisone or a placebo arm. The multi-center trial will be conducted in eight German headache clinics that specialize in the treatment of ECH. DISCUSSION: PredCH is designed to assess whether oral prednisone added to first-line agent verapamil helps reduce the number and intensity of cluster attacks in the beginning of a cluster episode as compared to monotherapy with verapamil.

The Efficacy of Short-Term Bridging Strategies With High- and Low-Dose Prednisolone on Radiographic and Clinical Outcomes in Active Early Rheumatoid Arthritis: A Double-Blind, Randomized, Placebo-Controlled Trial.

OBJECTIVE: In active early rheumatoid arthritis (RA), glucocorticoids are often used for bridging, due to the delayed action of methotrexate. This study was undertaken to compare the effect of 3 bridging strategies, including high-dose and low-dose prednisolone, on radiographic and clinical outcomes. METHODS: Adult RA patients from 1 rheumatology hospital and 23 rheumatology practices who presented with moderate/high disease activity were randomized (1:1:1) to receive 60 mg prednisolone (high-dose prednisolone [HDP]) or 10 mg prednisolone (low-dose prednisolone [LDP]) daily (tapered to 0 mg within 12 weeks) or placebo. The 12-week intervention period was followed by 40 weeks of therapy at the physicians' discretion. The primary outcome measure was radiographic change at 1 year measured using the total modified Sharp/van der Heijde score (SHS). Disease activity was assessed with the Disease Activity Score in 28 joints using the erythrocyte sedimentation rate (DAS28-ESR). RESULTS: Of 395 randomized patients (HDP, n = 132; LDP, n = 131; placebo, n = 132), 375 (95%) remained in the modified intention-to-treat analysis. Mean ± SD changes in SHS scores in the 3 groups after 1 year were comparable: mean ± SD 1.0 ± 2.0 units in the HDP group, 1.1 ± 2.2 units in the LDP group, and 1.1 ± 1.5 units in the placebo group. The primary analysis showed no superiority of HDP compared to placebo (estimated difference of the mean change -0.04 [95% confidence interval (95% CI) -0.5, 0.4]). At week 12, the mean DAS28-ESR differed: -0.6 (95% CI -1.0, -0.2) for HDP versus placebo; -0.8 (95% CI -1.2, -0.5) for LDP versus placebo. At week 52, there was no significant difference in DAS28-ESR between the 3 groups (range 2.6-2.8). Serious adverse events occurred similarly often. CONCLUSION: Short-term glucocorticoid bridging therapy at a high dose showed no benefit with regard to progression of radiographic damage at 1 year.

Optimizing blood pressure control by an Information Communication Technology-supported case management (PIA study): study protocol for a cluster-randomized controlled trial of a delegation model for general practices.

BACKGROUND: Longitudinal hypertension control prevents heart attacks, strokes, and other cardiovascular diseases. However, 49% of patients in German family medicine practices do not reach blood pressure (BP) targets (< 140/90 mmHg). Drawing on successful international approaches, the PIA study introduces the PIA information and communication technology system (PIA-ICT) for hypertension management in primary care. The PIA-ICT comprises the PIA-App for patients and the PIA practice management center for practices. Case management includes electronic communication with patients, recall, and stepwise medication adjustments following guidelines. The system supports a physician-supervised delegation model to practice assistants. General practitioners are qualified by eLearning. Patients learn how to obtain reliable BP readings, which they communicate to the practice using the PIA-App. METHODS: The effectiveness of the PIA-Intervention is evaluated in a cluster-randomized study with 60 practices, 120 practice assistants, and 1020 patients. Patients in the intervention group receive the PIA-Intervention; the control group receives usual care. The primary outcome is the BP control rate (BP < 140/90 mmHg) after 12 months. Using a mixed methods approach, secondary outcomes address the acceptance on behalf of physicians, practice assistants, and patients. This includes an evaluation of the delegation model. DISCUSSION: It is hypothesized that the PIA-Intervention will improve the quality of BP care. Perspectively, it may constitute an important health service model for primary care in Germany.

Safety and efficacy of prednisone versus placebo in short-term prevention of episodic cluster headache: a multicentre, double-blind, randomised controlled trial.

BACKGROUND: Prednisone is commonly used for initial short-term therapy of episodic cluster headaches before preventive medication such as verapamil becomes effective, but this strategy has not been tested in large randomised trials. We aimed to access the safety and efficacy of this treatment approach. METHODS: This study was a multicentre, randomised, double-blind, placebo-controlled trial done in ten specialised headache centres in Germany. Patients with episodic cluster headaches who were aged between 18 and 65 years and within a current pain episode for not more than 30 days, received 100 mg oral prednisone for 5 days followed by tapering of 20 mg every 3 days, or matching placebo (17 days total exposure). All patients received oral verapamil for long-term prevention, starting with 40 mg three times daily and increasing to 120 mg three times daily by day 19; patients then continued with verapamil 120 mg throughout the study. Randomisation was computer-generated at a 1:1 ratio by use of an interactive web-response system, with stratification according to age, sex, and participating site. Participants, investigators, and those assessing outcomes were unaware of treatment allocation. The primary endpoint was the mean number of attacks within the first week of treatment with prednisone compared with placebo. An attack was defined as a unilateral headache with moderate-to-severe intensity of at least five on a numerical rating scale. All efficacy and safety analyses were done in the modified intention-to-treat (mITT) population, which consisted of all patients who had been randomly assigned to a trial group and received at least one dose of prednisone or placebo. The study was stopped early due to slow recruitment and expired funding. The study was registered with EudraCT (2011-006204-13) and with the German Clinical Trials Register (DRKS00004716). FINDINGS: Between April 5, 2013, and Jan 11, 2018, 118 patients were enrolled in the study. Two patients dropped out immediately and 116 patients were randomly assigned (57 patients to prednisone and 59 patients to placebo); 109 patients were included in the mITT analysis (53 patients assigned to prednisone and 56 patients assigned to placebo). Participants in the prednisone group had a mean of 7·1 (SD 6·5) attacks within the first week compared with 9·5 (6·0) attacks in the placebo group (difference -2·4 attacks, 95% CI -4·8 to -0·03; p=0·002). Two serious adverse events occurred, both in the placebo group (inguinal hernia and severe deterioration of cluster headache). A total of 270 adverse events were observed: in the prednisone group, 37 (71%) of 52 patients reported 135 adverse events (most common were headache, palpitations, dizziness, and nausea) and in the placebo group, 39 (71%) of 55 patients had 135 adverse events (most common were nausea, dizziness, and headache). INTERPRETATION: Oral prednisone was an effective short-term preventive therapy in our population of patients with episodic cluster headache. Our findings support the use of prednisone as a first-line treatment in parallel to the up-titration of verapamil, although the efficacy of prednisone alongside other long-term prevention requires additional investigation.

IMPROVEjob - Participatory intervention to improve job satisfaction of general practice teams: a model for structural and behavioural prevention in small and medium-sized enterprises - a study protocol of a cluster-randomised controlled trial.

BACKGROUND: Perceived high chronic stress is twice as prevalent among German general practitioners (GPs) and non-physician medical staff compared to the general population. The reasons are multi-factorial and include patient, practice, healthcare system and societal factors, such as multi-morbidity, the diversity of populations and innovations in medical care. Also, practice-related factors, like stressful patient-staff interactions, poor process management of waiting times and lack of leadership, play a role. This publicly funded study evaluates the effectiveness of the newly developed participatory, interdisciplinary, and multimodal IMPROVEjob intervention on improving job satisfaction among general practice personnel. The intervention aims at structural stress prevention with regard to working conditions and behavioural stress prevention for leaders and other practice personnel. METHODS: In this cluster-randomised controlled trial, a total of 56 general practices will be assigned to either (1) participation in the IMPROVEjob intervention or (2) the waiting-list control group. The IMPROVEjob intervention consists of the following elements: three workshops, a toolbox with supplemental material and an implementation period with regular contact to so-called IMPROVEjob facilitators. The first workshop, addressing leadership issues, is designed for physicians with leadership responsibilities only. The two subsequent workshops target all GP and non-physician personnel; they address issues of communication (with patients and within the team), self-care and team-care and practice organisation. During the 9-month implementation period, practices will be contacted by IMPROVEjob facilitators to enhance motivation. Additionally, the practices will have access to the toolbox materials online. All participants will complete questionnaires at baseline and follow up. The primary outcome is the change in job satisfaction as measured by the respective scale of the validated German version of the Copenhagen Psychosocial Questionnaire (COPSOQ, version 2018). Secondary outcomes obtained by questionnaires and - qualitatively - by facilitators comprise psychosocial working conditions including leadership aspects, expectations and experiences of the workshops, team and individual efforts and organisational changes. DISCUSSION: It is hypothesised that participation in the IMPROVEjob intervention will improve job satisfaction and thus constitute a structural and behavioural prevention strategy for the promotion of psychological wellbeing of personnel in general practices and prospectively in other small and medium sized enterprises.

Nusinersen in adults with 5q spinal muscular atrophy: a non-interventional, multicentre, observational cohort study.

BACKGROUND: Nusinersen is approved for the treatment of 5q spinal muscular atrophy of all types and stages in patients of all ages. Although clinical trials have shown improvements in motor function in infants and children treated with the drug, data for adults are scarce. We aimed to assess the safety and efficacy of nusinersen in adults with 5q spinal muscular atrophy. METHODS: We did an observational cohort study at ten academic clinical sites in Germany. Patients with genetically confirmed 5q spinal muscular atrophy (age 16-65 years) with a homozygous deletion of exons 7, 8, or both, or with compound heterozygous mutations were eligible for inclusion and received nusinersen treatment in accordance with the label for a minimum treatment time of 6 months to a follow-up of up to 14 months. The primary outcome was the change in the total Hammersmith Functional Motor Scale Expanded (HFMSE) score, assessed at months 6, 10, and 14, and based on pre-post comparisons. This study is registered with the German Clinical Trials Register (number DRKS00015702). FINDINGS: Between July 13, 2017, and May 1, 2019, 173 patients were screened, of whom 139 (80%) were eligible for data analysis. Of these, 124 (89%) were included in the 6-month analysis, 92 (66%) in the 10-month analysis, and 57 (41%) in the 14-month analysis; patients with missing baseline HFMSE scores were excluded from these analyses. Mean HFMSE scores were significantly increased compared with baseline at 6 months (mean difference 1·73 [95% CI 1·05-2·41], p<0·0001), 10 months (2·58 [1·76-3·39], p<0·0001), and 14 months (3·12 [2·06-4·19], p<0·0001). Clinically meaningful improvements (≥3 points increase) in HFMSE scores were seen in 35 (28%) of 124 patients at 6 months, 33 (35%) of 92 at 10 months, and 23 (40%) of 57 at 14 months. To 14-month follow-up, the most frequent adverse effects among 173 patients were headache (61 [35%] patients), back pain (38 [22%]), and nausea (19 [11%]). No serious adverse events were reported. INTERPRETATION: Despite the limitations of the observational study design and a slow functional decline throughout the natural disease course, our data provide evidence for the safety and efficacy of nusinersen in the treatment of adults with 5q spinal muscular atrophy, with clinically meaningful improvements in motor function in a real-world cohort. FUNDING: None.

A randomised, placebo-controlled, 24-week, study of low-dose extended-release methylphenidate in adults with attention-deficit/hyperactivity disorder.

INTRODUCTION: Attention-deficit/hyperactivity disorder (ADHD) affects many adults who had ADHD in childhood. Although stimulants and methylphenidate in particular are a common off-label treatment for adult patients with ADHD in European countries, little is known about their long-term efficacy and safety. METHODS: A randomized, 24-week double-blind, placebo-controlled, parallel-design study of extended-release methylphenidate (MPH ER) in 359 adult individuals with ADHD according to DSM-IV. Standardized instruments were used for diagnosis. Treatment was started with MPH ER doses of 10 mg/day and titrated up to 60 mg/day, depending on individual efficacy and tolerability. Mean daily MPH SR dose was 0.55 mg/kg. RESULTS: Treatment with MPH ER resulted in clinical and statistically significant reductions of ADHD symptoms rated with the Wender-Reimherr adult attention deficit disorder scale (WRAADDS) and symptoms of inattention and hyperactivity/impulsivity according to DSM-IV, respectively. Improvements were maintained significant versus placebo up to week 24 of treatment. At endpoint, 61% of the subjects receiving MPH ER were rated as responders according to the a priori definition of response of more than 30% reduction of the WRAADDS score, compared to 42% in the placebo group. The second defined response criterion of much or very much improved on the clinical global impression scale (CGI) was fulfilled by 55% of subjects receiving MPH ER and 37% of subjects receiving placebo. MPH ER treatment was associated with a statistically significant increase of pulse at week 4 (72 bpm at baseline, 77 bpm at week 4). There were no significant differences of heart rate or blood pressure between treatment and placebo groups at any time point. DISCUSSION: MPH ER treatment in low to moderate doses was effective and safe in the treatment of ADHD in adults. Efficacy measures were clinical and statistically significant and robustly sustained during the 24-week observation period. In this study, no clinical significant effects on blood pressure but a transient increase of the heart rate were found. The interpretation of the results is limited by the low dose-range used in this study, the high drop-out rate and placebo-response which might have affected the therapeutic effect size.

Perioperative course and quality of life in a prospective randomized multicenter phase III trial, comparing standard lobectomy versus anatomical segmentectomy in patients with non-small cell lung cancer up to 2 cm, stage IA (7th edition of TNM staging system).

OBJECTIVES: For early stage non-small cell lung cancer (NSCLC) retrospective data of functionally compromised patients undergoing segmentectomy showed equal outcomes for perioperative complications and quality of life (QoL) compared with lobectomy patients. However no prospectively randomized data comparing patients eligible for both procedures are available. MATERIALS AND METHODS: We conducted a prospective, randomized, multicenter phase III trial and investigated perioperative complications and QoL in patients with NSCLC stage IA (7th edition) undergoing segmentectomy versus lobectomy. The EORTC Questionnaire Core-30 (QLQ C-30) supplemented by thirteen-item lung cancer-specific module (LC13) was assessed before surgery, at discharge, 6 weeks, 3, 6 and 12 months post-surgery. RESULTS: 108 patients with verified or suspected NSCLC up to 2 cm diameter were enrolled, whereby 54 were assigned to lobectomy and 54 to segmentectomy. Due to nodal disease, tumor size and surgical reasons estimated during the operation, eight patients of the segmentectomy group received a lobectomy. In hospital and 90 days mortality was 0% in both groups. Perioperative complications were observed in 6 (11.3%) patients after segmentectomy and in 8 patients (14.8%) after lobectomy (p = 0.563), while the 90-day morbidity were 17% and 25.9% (9 and 14 patients), respectively (p = 0.452). Twelve months after surgery, there was a significant deterioration to the baselines of physical (p < 0.001) and cognitive functioning (p = 0.025), dyspnea (p < 0.001) and fatigue (p = 0.003) in the lobectomy group. Dyspnea showed a faster recovery in the segmentectomy compared to lobectomy group with statistical significance (p = 0.016 after 12 months). CONCLUSION: In patients with early-stage NSCLC, segmentectomy is associated with a statistically not significant lower perioperative morbidity and appears to provide a superior recovery in QoL compared with lobectomy patients.

Positron Emission Tomography-Guided Therapy of Aggressive Non-Hodgkin Lymphomas (PETAL): A Multicenter, Randomized Phase III Trial.

Purpose Interim positron emission tomography (PET) using the tracer, [18F]fluorodeoxyglucose, may predict outcomes in patients with aggressive non-Hodgkin lymphomas. We assessed whether PET can guide therapy in patients who are treated with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP). Patients and Methods Newly diagnosed patients received two cycles of CHOP-plus rituximab (R-CHOP) in CD20-positive lymphomas-followed by a PET scan that was evaluated using the ΔSUVmax method. PET-positive patients were randomly assigned to receive six additional cycles of R-CHOP or six blocks of an intensive Burkitt's lymphoma protocol. PET-negative patients with CD20-positive lymphomas were randomly assigned or allocated to receive four additional cycles of R-CHOP or the same treatment with two additional doses rituximab. The primary end point was event-free survival time as assessed by log-rank test. Results Interim PET was positive in 108 (12.5%) and negative in 754 (87.5%) of 862 patients treated, with statistically significant differences in event-free survival and overall survival. Among PET-positive patients, 52 were randomly assigned to R-CHOP and 56 to the Burkitt protocol, with 2-year event-free survival rates of 42.0% (95% CI, 28.2% to 55.2%) and 31.6% (95% CI, 19.3% to 44.6%), respectively (hazard ratio, 1.501 [95% CI, 0.896 to 2.514]; P = .1229). The Burkitt protocol produced significantly more toxicity. Of 754 PET-negative patients, 255 underwent random assignment (129 to R-CHOP and 126 to R-CHOP with additional rituximab). Event-free survival rates were 76.4% (95% CI, 68.0% to 82.8%) and 73.5% (95% CI, 64.8% to 80.4%), respectively (hazard ratio, 1.048 [95% CI, 0.684 to 1.606]; P = .8305). Outcome prediction by PET was independent of the International Prognostic Index. Results in diffuse large B-cell lymphoma were similar to those in the total group. Conclusion Interim PET predicted survival in patients with aggressive lymphomas treated with R-CHOP. PET-based treatment intensification did not improve outcome.

A Structured, Manual-Based Low-Level Intervention vs. Treatment as Usual Evaluated in a Randomized Controlled Trial for Adolescents with Extreme Obesity - the STEREO Trial.

BACKGROUND: To compare efficacy and safety of a manual-based low-level psychological intervention with treatment as usual (weight loss treatment). METHODS: A two-armed randomized controlled trial without blinding and computer-based stratified block randomization included adolescents and young adults (14.0-24.9 years) with a BMI ≥ 30 kg/m2 at five German university hospitals. Primary outcomes were adherence (participation rate ≥ 5/6 sessions) and quality of life (DISABKIDS-37) 6 months after randomization. Secondary outcomes included depression, self-esteem, and perceived stress scores. RESULTS: Of 397 screened adolescents, 119 (mean BMI 40.4 ± 7.0 kg/m2, 49.6% female) were randomized to the manual-based low-level intervention (n = 59) or treatment as usual (n = 60). We observed no group difference for adherence (absolute risk reduction 0.4%, 95% CI -14.7% to 15.5%; p = 1.0) or health-related quality of life (score difference 8.1, 95% CI -2.1 to 18.3; p = 0.11). Among all secondary outcomes, we detected explorative evidence for an effect on the DISABKIDS-37 'social exclusion' subscale (score difference 15.5; 95% CI 1.6-29.4; p = 0.03). 18/19 adverse events occurred in 26 participants, none were classified as serious. CONCLUSION: Adherence to a coping-oriented intervention was comparable to weight loss treatment, although it was weak in both interventions. Psychological interventions may help to overcome social isolation; further confirmation is required.
