Given today's challenges, companies are confronted with pressing questions: Are marketing and sustainability a contradiction? How can digitalization support marketers beyond digital advertising? These questions must be addressed in an international context since, for most companies, international business is more a reality than just a strategic option as it was just a few decades ago. This book provides insights into the fundamentals of international marketing with a focus on these topics because they are commonplace in today's international marketing. It presents theories and concepts of international marketing in a concise form along with many real-world examples. The book explores how digitalization makes potential connections and advances available to marketing and how marketing can contribute to shaping a more sustainable future. It is a must read for students interested in the topic and managers who are confronted with these challenges. Supplementary materials for the book are available!

Abstract: Importance Knowledge about the long-term effects of multimodal treatment in adult attention-deficit/hyperactivity disorder (ADHD) is much needed. Objective To evaluate the long-term efficacy of multimodal treatment for adult ADHD. Design, Setting, and Participants This observer-masked, 1.5-year follow-up of the Comparison of Methylphenidate and Psychotherapy in Adult ADHD Study (COMPAS), a prospective, multicenter randomized clinical trial, compared cognitive behavioral group psychotherapy (GPT) with individual clinical management (CM) and methylphenidate (MPH) with placebo (2 × 2 factorial design). Recruitment started January 2007 and ended August 2010, and treatments were finalized in August 2011 with follow-up through March 2013. Overall, 433 adults with ADHD participated in the trial, and 256 (59.1%) participated in the follow-up assessment. Analysis began in November 2013 and was completed in February 2018. Interventions After 1-year treatment with GPT or CM and MPH or placebo, no further treatment restrictions were imposed. Main Outcomes and Measures The primary outcome was change in the observer-masked ADHD Index of Conners Adult ADHD Rating Scale score from baseline to follow-up. Secondary outcomes included further ADHD rating scale scores, observer-masked ratings of the Clinical Global Impression scale, and self-ratings of depression on the Beck Depression Inventory. Results At follow-up, 256 of 433 randomized patients (baseline measured in 419 individuals) participated. Of the 256 patients participating in follow-up, the observer-masked ADHD Index of Conners Adult ADHD Rating Scale score was assessed for 251; the mean (SD) baseline age was 36.3 (10.1) years; 125 patients (49.8%) were men; and the sample was well-balanced with respect to prior randomization (GPT and MPH: 64 of 107; GPT and placebo: 67 of 109; CM and MPH: 70 of 110; and CM and placebo: 55 of 107). At baseline, the all-group mean ADHD Index of Conners Adult ADHD Rating Scale score was 20.6, which improved to adjusted means of 14.2 for the GPT arm and 14.7 for the CM arm at follow-up with no significant difference between groups (difference, −0.5; 95% CI, −1.9 to 0.9; P = .48). The adjusted mean decreased to 13.8 for the MPH arm and 15.2 for the placebo arm (difference, −1.4; 95% CI, −2.8 to −0.1; P = .04). As in the core study, MPH was associated with a larger reduction in symptoms than placebo at follow-up. These results remained unchanged when accounting for MPH intake at follow-up. Compared with participants in the CM arm, patients who participated in group psychotherapy were associated with less severe symptoms as measured by the self-reported ADHD Symptoms Total Score according to the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) (DSM-IV) of Conners Adult ADHD Rating Scale (AMD, −2.1; 95% CI, −4.2 to −0.1; P = .04) and in the subscale of reducing pure hyperactive symptoms, measured via the Diagnostic Checklist for the diagnosis of ADHD in adults (AMD, −1.3; 95% CI, −2.8 to 0.1; P = .08). Regarding the Clinical Global Impression scale assessment of effectiveness, the difference between GPT and CM remained significant at follow-up (odds ratio, 1.63; 95% CI, 1.03-2.59; P = .04). No differences were found for any comparison concerning depression as measured with the Beck Depression Inventory. Conclusions and Relevance Results from COMPAS demonstrate a maintained improvement in ADHD symptoms for adults 1.5 years after the end of a 52-week controlled multimodal treatment period. The results indicate that MPH treatment combined with GPT or CM provides a benefit lasting 1.5 years. Confirming the results of the core study, GPT was not associated with better results regarding the primary outcome compared with CM. Trial Registration isrctn.org Identifier: ISRCTN54096201

Abstract: The utility of amyloid positron emission tomography (PET) for the etiological diagnosis of dementia and its impact on functional status of patients in routine care are currently unclear. Here, we describe the design of ENABLE, a randomized controlled two-armed coverage with evidence development (CED) study in Germany. Approximately 1126 patients with mild to moderate dementia of unclear etiology will be randomly assigned to either an amyloid PET or a no amyloid PET group. Patients will be followed-up for 24 months. The study has been registered at the German Clinical Trials Register (https://drks.de/search/de/trial/DRKS00030839) with the registration code DRKS00030839. The primary endpoint of ENABLE is the ability to perform functional activities of daily living at 18 months. Secondary endpoints include change in diagnosis, diagnostic confidence, and cognitive and clinical outcomes of patients. We expect that the CED study ENABLE will inform about patient relevant effects of amyloid PET in routine care. Furthermore, we anticipate that ENABLE will support physicians' and payers' decisions on provision of health care for patients with dementia. Highlights Study design focuses on the usefulness of amyloid positron emission tomography (PET) in routine care. Study design addresses the patient-relevant effect of amyloid PET. Patient representatives were involved in the creation of the study design. The study will help improve routine care for people with dementia

Sustainability has been defined by the Brundtland Commission (Brundtland, 1987) as "meeting the needs of the present without compromising the ability of future generations to meet their own needs". In times of increasing expectations of customers, shareholders, employees, and communities as well as the general public about corporations' contributions to sustainability (WBCSD - World Business Council for Sustainable Development), the latter are severely and continuously criticized for actions that contradict their glossy sustainability reports (Holliday, 2010). However, it is often the case that such criticism is rooted in a lack of awareness of the complexity of relationships and the role that sustainability plays within the context of a firm's operations, particularly SMEs, which cannot dedicate major resources to cope with the issues. Therefore, the question arises of what universities can do to build awareness and understanding among students in order to prepare them to cope with sustainability aspects in their future careers (Starik et al., 2010). This paper presents findings based on quantitative and qualitative data from five consecutive crossfunctional courses in sustainability for students in business, law, architecture, health management and engineering, and evaluates the extent to which their attitude and awareness changed over the course. Recommendations are given for institutions in higher education as well as for companies to follow up with further training initiatives for junior managers.

Abstract: PURPOSE We evaluated circulating tumor DNA (ctDNA) for detecting tumor burden in melanoma and examined whether early changes in the number of ctDNA copies predict response to treatment. PATIENTS AND METHODS We included 12 patients with stage III and 50 patients with stage IV melanoma with BRAF exon 15 or NRAS exon 3 mutations in tumor tissue. We used droplet digital polymerase chain reaction to retrospectively analyze serial plasma samples for mutation-positive ctDNA. RESULTS Matched plasma and serum samples were positive for ctDNA, lactate dehydrogenase, and S100 in 113 (45.8%), 108 (43.7%; not significant), and 58 (23.5%; P .0001) of 247 samples from 50 patients with stage IV melanoma, and in 17 (63%), eight (29.6%; P = .014), and five (18.5%; P .0001) of 27 samples from 12 patients with stage III melanoma. The number of mutant ctDNA copies correlated with concentrations of lactate dehydrogenase (r = 0.50) and S100 (r = 0.64), tumor volume (r2 = 0.58), and tumor metabolic activity (r2 = 0.83). Within 30 days before surgery, initiation of treatment, or change in treatment, ctDNA, LDH, and S100 were positive in 76.8%, 53.6% (P = .01), and 46.4% (P .001) of patients, respectively. In patients with stage III or IV melanoma, early changes in ctDNA within 1 month after initiation of treatment correctly predicted RECIST response categories in 19 of 20 patients. Detectable ctDNA within 30 days after surgery or initiation of systemic treatment predicted inferior progression-free survival in patients with stage III disease (P = .018). In patients with stage IV disease, 10 or more copies of ctDNA per mL at first follow-up indicated shorter progression-free survival (3.8 v 9 months; hazard ratio, 4.05; 95% CI, 1.56 to 10.53).

Abstract: We performed a prospective study of circulating immune cell changes after stereotactic body radiotherapy (SBRT) in 50 early-stage NSCLC patients. We found no significant increase in CD8+ cytotoxic T lymphocytes at first follow-up (the primary endpoint) but detected a significant increase in expanding Ki-67+CD8+ and Ki-67+CD4+ T-cell fractions in patients treated with 10 Gy or less per fraction. SBRT can induce significant expansion in circulating effector T-cells immediately post-treatment

Abstract: Background Most people with dementia (PwD) are cared for at home, with general practitioners (GPs) playing a key part in the treatment. However, primary dementia care suffers from a number of shortcomings: Often, diagnoses are made too late and therapies by GPs do not follow the guidelines. In cases of acute crises, PwD are too often admitted to hospital with adverse effects on the further course of the disease. The aim of this study is to implement and evaluate a new GP-based, complex dementia care model, DemStepCare. DemStepCare aims to ensure demand-oriented, stepped care for PwD and their caregivers. Methods/design In a cluster randomized controlled trial, the care of PwD receiving a complex intervention, where the GP is supported by a multi-professional team, is compared to (slightly expanded) usual care. GPs are clustered by GP practice, with 120 GP practices participating in total. GP practices are randomized to an intervention or a control group. 800 PwD are to be included per group. Recruitment takes place in Rhineland-Palatinate, Germany. In addition, a second control group with at least 800 PwD will be formed using aggregated routine data from German health insurance companies. The intervention comprises the training of GPs, case management including repeated risk assessment of the patients' care situation, the demand-oriented service of an outpatient clinic, an electronic case record, external medication analyses and a link to regional support services. The primary aims of the intervention are to positively influence the quality of life for PwD, to reduce the caregivers' burden, and to reduce the days spent in hospital. Secondary endpoints address medication adequacy and GPs' attitudes and sensitivity towards dementia, among others. Discussion The GP-based dementia care model DemStepCare is intended to combine a number of promising interventions to provide a complex, stepped intervention that follows the individual needs of PwD and their caregivers. Its effectiveness and feasibility will be assessed in a formative and a summative evaluation.
