        Quality of Life of Psoriasis Patients before and after Balneo - or Balneophototherapy

        Stefano Tabolli,Anna Calza,Cristina Di Pietro,Francesca Sampogna,Damiano Abeni 연세대학교의과대학 2009 Yonsei medical journal Vol.50 No.2

        Purpose: An observational prospective study was conducted to study the effects of hypotonic spa-water baths and narrowband ultraviolet B therapy given alone or in combination for treatment of moderate-severe psoriasis. Materials and Methods: Two treatments were analysed: 2 weeks of balneotherapy followed by ultraviolet-B (UVB) 311-nm phototherapy (BPT) or 2 weeks of daily bath treatments of Comano water alone (BT). One hundred and eleven adult patients with moderate to severe chronic plaque psoriasis were enrolled. Quality of life (QoL) questionnaires {36-item Short Form of the Medical Outcomes Study questionnaire (SF-36) and Skindex-29} were administered at baseline and 2 months from the end of therapy. The self-administered Psoriasis Area Severity Index (SAPASI), and the General Health Questionnaire (GHQ)-12 (to assess clinical severity and psychological distress, respectively) were also recorded at the same time-periods. Results: SAPASI was significantly reduced from 15.2 to 8.7 in BPT group and 11.6 to 7.8 in BT. A decrease of greater than 50% after therapy in SAPASI_50 score was reached by 42% and 37% of patients in the BPT and BT groups, respectively. At follow-up, both groups had better scores on all SF-36 scales (with statistically significant improvement in social functioning and mental health in the BPT group) and in all Skindex-29 scales. A statistically significant reduction of GHQ-12 positive cases was observed in the BPT group. Conclusion: Comano spa-water alone or in combination with phototherapy had beneficial therapeutic effects on patients with psoriasis. Although our observational study design prevents us from making meaningful comparisons between the 2 interventions, the combination of balneo and phototherapy seems to improve QoL and lessen clinical severity, and reduced the proportion of GHQ-12 positive cases.

        Integration of somatic mutation, expression and functional data reveals potential driver genes predictive of breast cancer survival

        Suo, Chen,Hrydziuszko, Olga,Lee, Donghwan,Pramana, Setia,Saputra, Dhany,Joshi, Himanshu,Calza, Stefano,Pawitan, Yudi Oxford University Press 2015 Bioinformatics Vol.31 No.16

        <P><B>Motivation:</B> Genome and transcriptome analyses can be used to explore cancers comprehensively, and it is increasingly common to have multiple omics data measured from each individual. Furthermore, there are rich functional data such as predicted impact of mutations on protein coding and gene/protein networks. However, integration of the complex information across the different omics and functional data is still challenging. Clinical validation, particularly based on patient outcomes such as survival, is important for assessing the relevance of the integrated information and for comparing different procedures.</P><P><B>Results:</B> An analysis pipeline is built for integrating genomic and transcriptomic alterations from whole-exome and RNA sequence data and functional data from protein function prediction and gene interaction networks. The method accumulates evidence for the functional implications of mutated potential driver genes found within and across patients. A driver-gene score (DGscore) is developed to capture the cumulative effect of such genes. To contribute to the score, a gene has to be frequently mutated, with high or moderate mutational impact at protein level, exhibiting an extreme expression and functionally linked to many differentially expressed neighbors in the functional gene network. The pipeline is applied to 60 matched tumor and normal samples of the same patient from The Cancer Genome Atlas breast-cancer project. In clinical validation, patients with high DGscores have worse survival than those with low scores (<I>P</I> = 0.001). Furthermore, the DGscore outperforms the established expression-based signatures MammaPrint and PAM50 in predicting patient survival. In conclusion, integration of mutation, expression and functional data allows identification of clinically relevant potential driver genes in cancer.</P><P><B>Availability and implementation:</B> The documented pipeline including annotated sample scripts can be found in http://fafner.meb.ki.se/biostatwiki/driver-genes/.</P><P><B>Contact:</B> yudi.pawitan@ki.se</P><P><B>Supplementary information:</B> Supplementary data are available at <I>Bioinformatics</I> online.</P>
