Identifying Technical Debt Impact on Maintenance Effort- An Industrial Case Study

Technical Debt refers to sub-optimal solutions in software development that affect the life cycle properties of a system. Source Code Technical Debt is considered to be a problem for many software projects, as neglecting Technical Debt on actively developed software will increase the required effort to maintain the software as well as to extend it with new features. However, refactoring Technical Debt also requires effort which is why it must be investigated if the Technical Debt is worth resolving. To be able to make such decisions, the existing Technical Debt must be correctly identified and presented in an understandable way. This thesis addresses the problem by conducting a case study at Ericsson, where Technical Debt in a large industrial C/C++ project has been investigated. The investigation was done by designing a measurement system based on ISO standard 15939:2007 and reviewing Technical Debt measurement tools suitable for its construction. The investigation also included correlating the resulting Technical Debt measurements with maintenance effort by applying triangulation of several methods. This allowed the Technical Debt types to be prioritized based on their correlation strength. The chosen Technical Debt measures are presented as a unified indicator that indicates file refactoring priority in order to support decision-making regarding Technical Debt Management, so that additional maintenance effort can be avoided in the future

Perspectives of Medical Oncologists regarding Music Therapy for Patients with Cancer in Turkey - Can Musicology be Integrated into Psycho-oncology?

Background: Music therapy is a common complementary and alternative therapy in addition to medical treatment for patients with cancer. If music therapy, which is known has a positive effect on human emotions and behaviors, is a useful additional therapy, it should be more integrated into pyscho-oncology. In this study, we aimed to determine medical oncologist attitudes to music therapy for patients with cancer and knowledge about musicology and music therapy in Turkey. Materials and Methods: This survey study included questions about participant attitudes and knowledge regarding music therapy as well as demographic characteristics. The population of the study were 402 physicians working in medical oncology in Turkey and the sample covered 112 participants in the the survey. For statistical analyses the chi-square test, Fischer exact test, and Mann-Whitney U analysis are applied. Results: In our study the rate for medical oncologists who were interested in music therapy was 28% (n=112). Some 30% (n=34) of medical oncologists recommended music therapy for their patients and 55% (n=61) recommended music therapy to prevent anxiety in patients with cancer. Conclusions: In this study, for more harmony with patients and in order to ensure management of adverse effect, it was concluded that music therapy should be regrded as an additional therapy in oncology clinics

Anti-Yo Antibody-mediated Paraneoplastic Cerebellar Degeneration in a Female Patient with Pleural Malignant Mesothelioma

Paraneoplastic cerebellar degeneration is a rare non-metastatic complication of malignancies. It presents with acute or subacute onset of ataxia, dysarthria and intention tremor. Paraneoplastic cerebellar degeneration is most commonly associated with malignancies of the ovary, breast and lung. The anti-Yo (anti-Purkinje cells) antibodies that specifically damage the Purkinje cells of the cerebellum are found in the serum and cerebrospinal fluid. Anti-Yo-related paraneoplastic cerebellar degeneration is most commonly found in women with gynecological and breast cancers, but it is reported in other malignancies. Patients with paraneoplastic syndromes most often present with neurologic symptoms before an underlying cancer is detected. We report a case of anti-Yo-related paraneoplastic cerebellar degeneration associated with pleural malignant mesothelioma in a 51-year-old female patient. She presented to our department with a 2-week history after the last chemotherapy of progressive diziness related to head movement, nausea, vomiting, ataxia and unsteady gait. A western blot assay was negative for anti-Hu, anti-Ri, anti-Ma2, anti-CV2 and anti-amphiphysin paraneoplastic antibody markers but positive for anti-Yo. In conclusion, we report a case of paraneoplastic cerebellar degeneration in a patient with pleural malignant mesothelioma because of the rarity of this neurologic presentation after the diagnosis of malignant mesothelioma and of the association with anti-Yo antibodies

Survivin and EPR-1 expression in acute leukemias: Prognostic significance and review of the literature

The aim of this study is to detect the biologic and/or prognostic significance of survivin (S) and effector protease receptor 1: EPR-1 (E) expression in acute leukemias (34 ALL and 40 AML) by using RT-PCR. S and E expressions were found in 83.8 and 20.3% of the cases, respectively. S was detected in 90%, 76.5% and E was detected in 17.5%, 23.5% of the cases with AML and ALL, respectively. There was a significant correlation between S and E (r=0.30 p=0.01). Mortality rate was higher in E(-) cases than E(+) cases (83.1 % versus 66.7%) (p=0.04). The median DFS and OS rates were shorter in S(+) and E(-) cases. In subgroup analysis, there was not a significant difference for OS between S(-) and S(+) cases and E(-) and E(+) cases in ALL group. The median OS rate was significantly longer in S(-) cases than S(+) cases, and longer in E(+) cases than E(-) in AML groups (p=0.04, 0.001, respectively). OS and DFS rates were longest in S(-) E(+) cases and shortest in S(+) E(-) cases (p=0.04 and 0.03, respectively). In multivariate analyses EPR1 negativity was found to be an independent poor risk factor for survival (OR: 2.4, p=0.02)

The Perspective of Non-oncologist Physicians on Patients with Metastatic Cancer and Palliative Care (ALONE Study): A Study of the Palliative Care Working Committee of the Turkish Oncology Group (TOG)

The aim of our study was to determine the perspective of non-oncologist physicians regarding their attitudes and beliefs associated with palliative care for patients with metastatic cancer. The study was planned as a cross-sectional survey, and non-oncologist physicians were reached via e-mail and social networking sites. The first part of the questionnaire involved demographic properties, the second part inquired as to the perspectives of participants regarding metastatic disease, and the third part was used to determine beliefs and attitudes about palliative care. All of the questions were five-point Likert-type questions. A total of 1734 physicians completed the questionnaire. The majority of participants were general surgeons or internal medicine specialists (21 and 18 %, respectively), were male (61 %), were younger than 50 years of age (54 %), worked in the town center (67 %), had more than 11 years of professional experience (57 %), and worked in a hospital without an active oncology service (86 %). A total of 71 % of participants identified all patients with metastatic cancer as being terminal stage, 62 % were unaware of palliative care techniques, 64 % did not know about common supportive care options, 59 % were against hospice, and 63 % had no opinion on resuscitation. We determined that non-oncologist physicians believed that all patients with metastatic cancer are at the terminal stage and that palliative/supportive care is the oncologist's task. These data suggest that non-oncologist physicians would benefit from additional graduate and postgraduate courses on these topics
