Supporting Medical Staff from Psycho-Oncology with Smart Mobile Devices: Insights into the Development Process and First Results.

Cancer is a very distressing disease, not only for the patients themselves, but also for their family members and relatives. Therefore, patients are regularly monitored to decide whether psychological treatment is necessary and applicable. However, such monitoring processes are costly in terms of required staff and time. Mobile data collection is an emerging trend in various domains. The medical and psychological field benefits from such an approach, which enables experts to quickly collect a large amount of individual health data. Mobile data collection applications enable a more holistic view of patients and assist psychologists in taking proper actions. We developed a mobile application, FeelBack, which is designed to support data collection that is based on well-known and approved psychological instruments. A controlled pilot evaluation with 60 participants provides insights into the feasibility of the developed platform and it shows the initial results. 31 of these participants received paper-based questionnaire and 29 followed the digital approach. The results reveal an increase of the overall acceptance by 58.5% in the mean when using a digital screening as compared to the paper-based. We believe that such a platform may significantly improve cancer patients' and relatives' psychological treatment, as available data can be used to optimize treatment.

Screening for Cognitive Function in Complete Immobility Using Brain-Machine Interfaces: A Proof of Principle Study.

Background: In many neurological conditions, there is a combination of decline in physical function and cognitive abilities. For far advanced stages of physical disability where speaking and hand motor abilities are severely impaired, there is a lack of standardized approach to screen for cognitive profile. Methods:N = 40 healthy subjects were included in the study. For proof of principle, N = 6 ALS patients were additionally measured. For cognitive screening, we used the Edinburgh cognitive and behavioral ALS screen (ECAS) in the standard paper-and-pencil version. Additionally, we adapted the ECAS to a brain-machine interface (BMI) control module to screen for cognition in severely advanced patients. Results: There was a high congruency between BMI version and the paper-and-pencil version of the ECAS. Sensitivity and specificity of the ECAS-BMI were mostly high whereas stress and weariness for the patient were low. Discussion/Conclusion: We hereby present evidence that adaptation of a standardized neuropsychological test for BMI control is feasible. BMI driven neuropsychological test provides congruent results compared to standardized tests with a good specificity and sensitivity but low patient load.

Sustained increases in numbers of pulmonary dendritic cells after respiratory syncytial virus infection.

BACKGROUND: Respiratory syncytial virus (RSV) bronchiolitis in infants can lead to wheezing and early allergic sensitization. In mice, RSV infection enhances allergic airway inflammation and airway hyperresponsiveness. Dendritic cells are critical in inducing T-cell responses to both viruses and allergens and could be pivotal in regulating interactions between these. OBJECTIVE: This study addresses the effects of RSV infection on phenotype and function of pulmonary dendritic cells. METHODS: BALB/c mice were infected with RSV, and expression of CD11c, MHC II, and CD86 on lung and spleen cells was monitored by flow cytometry for 21 days after infection. CD11c(+) cells were isolated to assess their phagocytic capacity and their ability to induce proliferation in allogenic T cells. RESULTS: Numbers of pulmonary CD11c(+) MHC II(hi) cells increased 13-fold starting from day 6 after RSV infection. This was associated with increased CD86 expression, reduced phagocytosis, and increased allogenic T-cell stimulatory capacity in CD11c(+) cells. These changes in the lung outlasted acute infection and were not observed in spleens. CONCLUSION: RSV infection results in sustained increases in numbers of mature dendritic cells in the lung. These might well contribute to the development of intense airway inflammation and airway hyperresponsiveness after RSV infection and to enhancement of subsequent responses to allergen exposure.
