RESUMO

PURPOSE: Distress screening has become mandatory and essential in comprehensive cancer care. We evaluated an electronic psycho-oncological adaptive screening (EPAS) which assesses objective indicators of care needs and subjectively perceived care needs and subsequently provides patient feedback with individualized recommendations about psychosocial care services. METHODS: Patients were assessed within clusters, i.e., different oncological facilities of the competence network of the University Cancer Center Hamburg (UCCH). Patients in the intervention arm underwent the screening, controls received standard care. Patients were assessed at baseline (t0), 3-month (t1), and 6-month (t2) follow-up. Outcomes included information level and use of/access to nine psychosocial services at UCCH, well-being (GAD-7, PHQ-9, SF-8), and treatment satisfaction (SCCC). Conditional linear and logistic regressions were used to identify screening effects at t1 and t2. RESULTS: Of 1320 eligible patients across 11 clusters, 660 were included (50%). The average age was 60 years; 46% were female. The intervention was associated with increased information level for all psychosocial services at t1 and t2 (all p < .001), increased use in some of these services at t1 and t2, respectively (p ≤ .02), and better evaluation of access (e.g., more recommendations for services provided by physicians, p < .01). At t2, the intervention was associated with a lower level of satisfaction with disease-related information (p = .02). CONCLUSIONS: EPAS may improve information about psychosocial services as well as utilization of and access to these services. The effect on information level seems not to be generalizable to other aspects of oncological care. Future studies should incorporate novel technologies and condense the procedure to its core factors. IMPLICATIONS FOR CANCER SURVIVORS: The screening may help to enhance self-management competencies among cancer survivors. TRIAL REGISTRATION: The trial was retrospectively registered (2/2021) at ClinicalTrials.gov (number: NCT04749056).

RESUMO

PURPOSE: The assessment of patient satisfaction during treatment is essential to provide patient-centered high-quality cancer care. Nevertheless, no German instrument assesses patient satisfaction with comprehensive cancer care, which not only includes oncological treatment, but also interpersonal quality of care as well as psychosocial support services. Based on the French REPERES-60, we developed the German Patient Satisfaction with Comprehensive Cancer Care (SCCC) questionnaire. METHODS: The REPERES-60 was translated and the items were adapted to make it applicable to the German healthcare system and across different tumor entities. Scales of the resulting instrument were extracted via principal axis factoring (PAF). Subsequently, we investigated the reliability (Cronbach's Alpha, CA), discriminatory power (corrected item-scale correlations) and convergent validity (pre-specified correlations of the SCCC with different outcomes). RESULTS: The SCCC consisted of 32 items which were subsequently tested among a sample of 333 patients across different tumor entities (response rate: 47%). Average age was 59 years (standard deviation: 14), 63% were male. PAF revealed four multi-item scales named Competence, Information, Access and Support accounting for 71% of the variance. Two single-items scales assess global satisfaction with medical and psychosocial care, respectively. CA across the multi-item scales ranged from .84 to .96. Discriminatory power was sufficiently high, with all r ≥ .5. Convergent validity was largely verified by negative associations of the four multi-item scales with depressive/anxious symptomatology (r ≥ - .18, p < .01) and fatigue/overall symptom burden (r ≥ - .14, p < .01). CONCLUSION: We developed a tool to assess patient satisfaction with comprehensive cancer care in Germany. The SCCC showed satisfactory psychometric properties. Further studies are needed to verify these preliminary findings.

RESUMO

Firefly luciferase is an enzyme that has found ubiquitous use in biological assays in high-throughput screening (HTS) campaigns. The inhibition of luciferase in such assays could lead to a false positive result. This issue has been known for a long time, and there have been significant efforts to identify luciferase inhibitors in order to enhance recognition of false positives in screening assays. However, although a large amount of publicly accessible luciferase counterscreen data is available, to date little effort has been devoted to building a chemoinformatic model that can identify such molecules in a given data set. In this study we developed models to identify these molecules using various methods, such as molecular docking, SMARTS screening, pharmacophores, and machine learning methods. Among the structure-based methods, the pharmacophore-based method showed promising results, with a balanced accuracy of 74.2%. However, machine-learning approaches using associative neural networks outperformed all of the other methods explored, producing a final model with a balanced accuracy of 89.7%. The high predictive accuracy of this model is expected to be useful for advising which compounds are potential luciferase inhibitors present in luciferase HTS assays. The models developed in this work are freely available at the OCHEM platform at http://ochem.eu .

RESUMO

OBJECTIVE: Although elevated levels of distress are supposed to constitute a need for psychosocial support, the relation between elevated distress and need for support does not appear to be straightforward. We aimed to determine cancer patients' perceived need for psychosocial support, and examine the relation of need to both self-reported emotional distress and the interview-based diagnosis of a mental disorder. METHODS: In a multicenter, cross-sectional study in Germany, 4020 cancer patients (mean age 58 years, 51% women) were evaluated. We obtained self-reports of need for psychosocial support. We measured distress with the National Comprehensive Cancer Network (NCCN) Distress Thermometer (DT) and depressive symptoms with the Patient Health Questionnaire (PHQ-9). In a subsample, we evaluated the presence of a mental disorder using the Composite International Diagnostic Interview (CIDI). RESULTS: 32.1% (95%-CI 30.6 to 33.6) of patients perceived a need for psychosocial support. Younger age, female sex, and higher education were associated with more needs, being married and living with a partner with fewer needs, respectively. While up to 51.2% of patients with elevated distress levels reported a need for psychosocial support, up to 26.1% of those without elevated distress levels perceived such a need. Results were similar across distress assessment methods. CONCLUSION: Our findings emphasize that the occurrence of mental distress is one important but not an exclusive factor among different motives to report the need for psychosocial support. We should thus consider multifaceted perspectives, facilitators and barriers when planning and implementing patient-centered psychosocial care services.

RESUMO

BACKGROUND: While psychosocial distress and supportive care needs of young adult cancer patients have been increasingly studied, little knowledge exists about preferences for communicating bad news. We aimed to analyze patients' communication preferences against their actual experiences with regard to doctor-patient interactions. PATIENTS AND METHODS: We surveyed a total of 270 cancer patients with different tumor entities. 3 age groups (young, middle-aged, and elderly) were compared concerning their communication preferences (MPP; Measure of Patients' Preferences questionnaire) and the impact on distress (National Comprehensive Cancer Network Distress Thermometer). RESULTS: We found no age differences of communication preferences and the content of bad news. A significant difference was found in the dimension 'professional expertise/patient orientation (p < 0.01) which was rated as more important by younger patients. Binary logistic regression showed an impact of 'children' (odds ratio (OR) 0.296; 95% confidence interval (CI) 0.155, 0.563), tumor staging (OR 1.737, 95% CI 1.028, 2.936), and insufficient 'privacy' (OR 0.987; 95% CI 0.978, 0.997) and 'clarity' (OR 1.013; 95% CI 1.002, 1.025) on distress. CONCLUSION: Communication preferences related to breaking bad news depend less on age differences than on other variables. Future studies should investigate the long-term impact of ineffective patient-physician communication, taking into account unmet patient preferences in different age groups.

RESUMO

BACKGROUND: Since a growing number of patients are likely to return to work (RTW) after cancer diagnosis and treatment, there is an increasing recognition of the work situation, and the physical as well as psychosocial functioning among those survivors who returned to work. OBJECTIVE: To prospectively examine Health Related quality of Life (HRQoL) and different aspects of work satisfaction in cancer survivors. PARTICIPANTS: N=702 employed cancer patients (85% women) were recruited on average 11 months post diagnosis and assessed at the beginning (t_1), the end (t_2) and 12 months after cancer rehabilitation program (t_3). METHODS: Participants completed validated measures assessing work satisfaction, working conditions, job strain and HRQoL. RESULTS: Participants showed a high work satisfaction and were most satisfied with job related activities and least satisfied with work organization and leadership. Total work satisfaction was significantly associated with older age, higher monthly income, higher school education, and HRQoL, but not with any cancer- or treatment related characteristics. No significant changes in work satisfaction over time were observed except for a significant deterioration in satisfaction with job related activities (p=0.002; η ^2 =0.019), professional acknowledgement (p=0.036; η ^2 =0.009), and overall work satisfaction (p < 0.001; η ^2 =0.087) with small to moderate effect sizes. CONCLUSIONS: Our findings emphasize the need for comprehensive cancer rehabilitation programs and specific vocational interventions.

RESUMO

Cancer rehabilitation is a rapidly emerging and evolving medical field in both Europe and the United States, in large part because of increases in the number of cancer survivors. Although few argue with the need to restore function and quality of life to patients affected by cancer and its treatments, differences exist between European countries with regard to the funding, accessibility, and even the definition of cancer rehabilitation services. In the United States, there is tremendous variability in the provision of rehabilitation services resulting from a variety of factors, including a lack of highly trained cancer rehabilitation physicians and therapists as well as a lack of comprehensive cancer rehabilitation programs, even at the majority of top cancer centers. Although studies evaluating the effectiveness of rehabilitation programs in the cancer setting, particularly exercise, have influenced clinical decision-making in both Europe and the United States for some time, this emerging evidence base also is now starting to influence guideline and policy making. Coordinated research efforts are essential to establish a robust framework to support future investigation and establish shared initiatives. Determining the best way forward for cancer survivors will require investment in large-scale prospective cohort studies that sufficiently describe their rehabilitation needs through the continuum of the survivorship experience.

RESUMO

PURPOSE: The recommendation to screen for distress and supportive care needs among cancer patients focuses on improving the quality, effectiveness, and efficiency of comprehensive cancer care. The purpose of this study was to test the psychometric properties of the German version of the Short-Form Supportive Care Needs Survey (SCNS-SF34-G). METHODS: One thousand forty-seven participants with heterogeneous tumor entities were recruited in inpatient and outpatient cancer care facilities (female, 51%; median age, 57 years; breast cancer, 26%; prostate cancer, 22%). Concurrent and divergent validity of the SCNS-SF34-G was analyzed through associations with measures of distress, depression, anxiety, and social support. RESULTS: Principal component analyses revealed five dimensions replicating the factorial structure of the original SCNS-SF34 (health system and information, psychological, physical and daily living, patient care and support, sexuality needs) explaining 68% of variance. Cronbach's alpha values ranged from 0.82 to 0.94. Convergent validity was supported by significant correlations between all SCNS-SF34-G subscales and psychosocial burden. Divergent validity was indicated by marginal correlations with social support. The SCNS-SF34-G was able to discriminate patient groups with respect to sex and age but not regarding tumor stage. CONCLUSIONS: The SCNS-SF34-G is an instrument with excellent psychometric properties for assessing supportive care needs among patients with various cancer entities. It seems to be useful to integrate the questionnaire into diagnostic assessment to tailor interventions according to patient needs. Further research is needed to gain knowledge of the development of unmet needs during the illness trajectory as well as of associations with offer and utilization of healthcare services.

RESUMO

Children of a parent having cancer are at greater risk to develop mental health problems. Aim is to investigate specific psychosocial care for children having a parent with cancer, as well as to characterize and assess utilization and needs of affected minor children. Employees of institutions in Germany supplying psychosocial care to families with a parent having cancer were surveyed, using a semi-structured interview (n = 29). Specific psychosocial care for affected children is limited and heterogeneous in Germany. Regarding different distress stages of those families, the situation could be interpreted as eligible. However, this primarily reflects the low quality assurance of care. Results suggest that in addition to preventive care needs of children having a parent with cancer, increased needs exist in specific risk constellations, like in single parent families.

RESUMO

MOTIVATION: The article presents results of the listing of the quantity of amino acids, dipeptides and tripeptides for all proteins available in the UNIPROT-TREMBL database and the listing for selected species and enzymes. UNIPROT-TREMBL contains protein sequences associated with computationally generated annotations and large-scale functional characterization. Due to the distinct metabolic pathways of amino acid syntheses and their physicochemical properties, the quantities of subpeptides in proteins vary. We have proved that the distribution of amino acids, dipeptides and tripeptides is statistical which confirms that the evolutionary biodiversity development model is subject to the theory of independent events. It seems interesting that certain short peptide combinations occur relatively rarely or even not at all. First, it confirms the Darwinian theory of evolution and second, it opens up opportunities for designing pharmaceuticals among rarely represented short peptide combinations. Furthermore, an innovative approach to the mass analysis of bioinformatic data is presented.

RESUMO

BACKGROUND: In recent years, the importance of guidelines has increased continuously. This development also occurs in the field of rehabilitative health care, where process guidelines are being designed for various indicational groups to ensure quality standards and improvements. AIM: The primary goal of this paper is to collect and evaluate the evidence for various treatment options for depressive disorders in order to establish a basis for the current development of a process guideline for the rehabilitation of patients with depressive disorders. METHOD: In order to identify evidence based treatment elements, first a comprehensive investigation of national and international guidelines was conducted. Thirteen selected guidelines were then assessed with regard to aspects of methodological quality and evidence-based treatment elements. In a further step, literature searches were conducted for residual treatment elements, which were identified on the basis of the Classification of Therapeutic Services (KTL) 2007. For the literature search, a hierarchical approach was chosen: At first, meta-analyses and systematic reviews were viewed. In case when there was still a lack of evidence for specific, potentially relevant treatment elements, the search was expanded to the level of primary studies. All selected reviews and primary studies then underwent a standardized assessment especially regarding methodological quality and evidence grades were allocated to treatments. RESULTS: Thereby, the following treatment elements with an adequate level of evidence were identified: Psychotherapeutic interventions, marital/couples/family therapy and counselling, inclusion of family members, psycho education and exercise, problem solving therapy, guided self-help, and behavioural activation treatments. On the basis of this complementary literature search, various other evident interventions could be identified within the following areas: relaxation techniques, improvement of social competence, occupational therapy, art therapies (music, movement/dance therapies), body-oriented therapies and massage therapy. CONCLUSION: In summary, using this hierarchical approach, it was possible to assign different levels of evidence to the various treatment elements for depression. Based on the results of this literature search, a next step in the development of a process guideline for the rehabilitative treatment of patients with depression will be the integration of experts in the field of rehabilitation.

RESUMO

Computational screening of compound databases has become increasingly popular in pharmaceutical research. This review focuses on the evaluation of ligand-based virtual screening using active compounds as templates in the context of drug discovery. Ligand-based screening techniques are based on comparative molecular similarity analysis of compounds with known and unknown activity. We provide an overview of publications that have evaluated different machine learning methods, such as support vector machines, decision trees, ensemble methods such as boosting, bagging and random forests, clustering methods, neuronal networks, naïve Bayesian, data fusion methods and others.

RESUMO

In many cases at the beginning of an HTS-campaign, some information about active molecules is already available. Often known active compounds (such as substrate analogues, natural products, inhibitors of a related protein or ligands published by a pharmaceutical company) are identified in low-throughput validation studies of the biochemical target. In this study we evaluate the effectiveness of a support vector machine applied for those compounds and used to classify a collection with unknown activity. This approach was aimed at reducing the number of compounds to be tested against the given target. Our method predicts the biological activity of chemical compounds based on only the atom pairs (AP) two dimensional topological descriptors. The supervised support vector machine (SVM) method herein is trained on compounds from the MDL drug data report (MDDR) known to be active for specific protein target. For detailed analysis, five different biological targets were selected including cyclooxygenase-2, dihydrofolate reductase, thrombin, HIV-reverse transcriptase and antagonists of the estrogen receptor. The accuracy of compound identification was estimated using the recall and precision values. The sensitivities for all protein targets exceeded 80% and the classification performance reached 100% for selected targets. In another application of the method, we addressed the absence of an initial set of active compounds for a selected protein target at the beginning of an HTS-campaign. In such a case, virtual high-throughput screening (vHTS) is usually applied by using a flexible docking procedure. However, the vHTS experiment typically contains a large percentage of false positives that should be verified by costly and time-consuming experimental follow-up assays. The subsequent use of our machine learning method was found to improve the speed (since the docking procedure was not required for all compounds from the database) and also the accuracy of the HTS hit lists (the enrichment factor).

RESUMO

The present article outlines the development of a system of categories of treatment goals in psychosomatic rehabilitation. As a first step a content analysis of 242 letters of discharge was carried out. In order to give a systematic describe of the thus extracted goals a system of categories was developed. Which was then in a second step used as the basis for detailed discussions by psychosomatic rehabilitation experts aimed at revising and optimizing the system of categories. This developed classification of treatment goals--owning to the possibility in principle of operationalization--will provide the conditions for further strategies within the context of evaluation and measures of quality assurance.
