Objectives: Patient-level factors that influence compliance with a recommendation for CBT in nursing home residents diagnosed with depression were identified.
Methods: Within a cluster-randomized trial on stepped care for depression in nursing homes (DAVOS-study, Trial registration: DRKS00015686), participants received an intake interview administered by a licensed psychotherapist. If psychotherapy was required, patients were offered a referral for CBT. Sociodemographic characteristics, severity of depression, loneliness, physical health, antidepressant medication, prior experience with psychotherapy, and attitudes towards own aging were assessed. A binary regression determined predictors of compliance with referral.
Results: Of 123 residents receiving an intake interview, 80 were recommended a CBT. Forty-seven patients (58.8 %) followed the recommendation. The binary logistic regression model on compliance with recommended CBT was significant, χ2(9) = 21.64, p = .010. Significant predictors were age (Odds Ratio (OR) = 0.9; 95 % Confidence Interval (CI) = 0.82, 0.99; p = .024) and depression (OR = 1.33; 95 % CI = 1.08, 1.65; p = .008).
Conclusion: Within the implemented setting compliance rate was comparable to other age groups. Future interventions should include detailed psychoeducation on the benefits of psychotherapy on mild depressive symptoms in older age and evidence-based interventions to address the stigma of depression. Interventions such as reminiscence-based methods or problem-solving could be useful to increase compliance with referral, especially in very old patients (80+). Language barriers and a culturally sensitive approach should be considered when screening residents.
Objectives: Investigate the effectiveness of a complex intervention aimed at improving the appropriateness of medication in older patients with multimorbidity in general practice.
Design: Pragmatic, cluster randomised controlled trial with general practice as unit of randomisation.
Setting: 72 general practices in Hesse, Germany.
Participants: 505 randomly sampled, cognitively intact patients (≥60 years, ≥3 chronic conditions under pharmacological treatment, ≥5 long-term drug prescriptions with systemic effects); 465 patients and 71 practices completed the study.
Interventions: Intervention group (IG): The healthcare assistant conducted a checklist-based interview with patients on medication-related problems and reconciled their medications. Assisted by a computerised decision support system, the general practitioner optimised medication, discussed it with patients and adjusted it accordingly. The control group (CG) continued with usual care.
Outcome measures: The primary outcome was a modified Medication Appropriateness Index (MAI, excluding item 10 on cost-effectiveness), assessed in blinded medication reviews and calculated as the difference between baseline and after 6 months; secondary outcomes after 6 and 9 months’ follow-up: quality of life, functioning, medication adherence, and so on.
Results: At baseline, a high proportion of patients had appropriate to mildly inappropriate prescriptions (MAI 0–5 points: n=350 patients). Randomisation revealed balanced groups (IG: 36 practices/252 patients; CG: 36/253). Intervention had no significant effect on primary outcome: mean MAI sum scores decreased by 0.3 points in IG and 0.8 points in CG, resulting in a non-significant adjusted mean difference of 0.7 (95% CI −0.2 to 1.6) points in favour of CG. Secondary outcomes showed non-significant changes (quality of life slightly improved in IG but continued to decline in CG) or remained stable (functioning, medication adherence).
Conclusions: The intervention had no significant effects. Many patients already received appropriate prescriptions and enjoyed good quality of life and functional status. We can therefore conclude that in our study, there was not enough scope for improvement.

The human cytomegalovirus (HCMV) is suspected to increase tumour malignancy by infection of cancer and/or stroma cells (oncomodulation). So far, oncomodulatory mechanisms have been attributed to the presence of HCMV and direct action of its gene products on cancer cells. Here, we investigated whether the prolonged presence of HCMV can result in the irreversible selection of a cancer cell population with increased malignancy. The neuroblastoma cell line UKF-NB-4 was long-term (200 passages) infected with the HCMV strain Hi91 (UKF-NB-4Hi) before virus eradication using ganciclovir (UKF-NB-4HiGCV). Global gene expression profiling of UKF-NB-4, UKF-NB-4Hi and UKF-NB-4HiGCV cells and subsequent bioinformatic signal transduction pathway analysis revealed clear differences between UKF-NB-4 and UKF-NB-4Hi, as well as between UKF-NB-4 and UKF-NB-4HiGCV cells, but only minor differences between UKF-NB-4Hi and UKF-NB-4HiGCV cells. Investigation of the expression of a subset of five genes in different chronically HCMV-infected cell lines before and after virus eradication suggested that long-term HCMV infection reproducibly causes specific changes. Array comparative genomic hybridisation showed virtually the same genomic differences for the comparisons UKF-NB-4Hi/UKF-NB-4 and UKF-NB-4HiGCV/UKF-NB-4. UKF-NB-4Hi cells are characterised by an increased invasive potential compared with UKF-NB-4 cells. This phenotype was completely retained in UKF-NB-4HiGCV cells. Moreover, there was a substantial overlap in the signal transduction pathways that differed significantly between UKF-NB-4Hi/UKF-NB-4HiGCV and UKF-NB-4 cells and those differentially regulated between tumour tissues from neuroblastoma patients with favourable or poor outcome. In conclusion, we present the first experimental evidence that long-term HCMV infection can result in the selection of tumour cell populations with enhanced malignancy.
