A tool framework for deriving the application architecture for global software development projects

In order to meet the communication, coordination and control requirements of distributed Global Software Development (GSD) teams, it is necessary to define a proper software architecture. Designing a GSD architecture, however, involves a multitude of design decisions that are related in different ways. As such, it is not trivial for the architect to design a system that meets the different GSD concerns. To assist the architect in designing a suitable GSD architecture we propose the tool framework Global Architect. The tool framework is based on a common meta-model for GSD and a question framework, which includes a predefined set of questions that are related to abstract design rules for designing GSD systems. Based on the answers provided to the questions of the question framework, the tool automatically selects and instantiates the necessary rules and generates the GSD architecture. Global Architect has been applied to design the GSD architecture for a real industrial project of Cybersoft, a leading GSD company in Turkey

Rituximab as a glucocorticoid-sparing agent in idiopathic inflammatory myopathies: a retrospective single-center cohort study

Background Idiopathic inflammatory myopathies (IIM) are essentially treated aiming to improve muscle function and extra muscular disease manifestations. Rituximab is potentially a glucocorticoid-sparing agent which was reviewed in multiple studies with small sample sizes due to the rarity of the disease. Higher statistical power can enhance the trustworthiness of alternative treatment modalities yielding the main objective of this study

Shear Wave Ultrasonographic Elastography in Pediatric Spleens and Its Role in Differential Diagnosis

Shear wave elastography (SWE) has become popular in clinical practice for many diseases. However, there is not adequate research on spleen-related diseases. This study aimed to investigate the potential of quantitative values obtained through SWE in evaluating spleen pathologies in the pediatric population and to demonstrate its performance to differentiate splenomegaly-related diseases. The research group retrospectively included children with pathological diagnoses related to the spleen from November 2016 to April 2021, and they were categorized into three groups, including portal hypertension (PH), benign lymphoid hyperplasia (BLH), and malignant infiltration (MI). Spleen sizes and parenchymal stiffness were also calculated for each group. Subsequently, mean spleen stiffness in each group was compared with normal values within the same age group. In total, 2781 children (1379 children for the study group; 1402 children for the control group) were enrolled in the study. The highest stiffness was observed in the PH group, which is statistically higher than others (p p = 0.08). The mean stiffness in the group with MI was significantly lower than both the control group (p = 0.005) and PH (p = 0.01). In conclusion, using SWE in the differential diagnosis of etiologies causing splenomegaly could make an important contribution

The Relationship Between ACE Polymorphism and Panic Disorder

Background: The angiotensin converting enzyme (ACE) gene, which has been found to have an insertion and deletion polymorphism (I/D), is of increasing interest in etiology and treatment of various psychiatric disorders such as panic disorder. The present study aimed to investigate the relationship between ACE polymorphism and panic disorder. Materials and Methods: In this study, 43 patients diagnosed with panic disorder at the Erenkoy Mental and Neurological Diseases Training and Research Hospital, Istanbul and 41 healthy controls were enrolled. The ACE gene insertion/deletion polymorphism of exon 16 was evaluated using the polymerase chain reaction method. Results: There was a significant association between I/D genotype and panic disorder (p=0.003). However, the frequency of the I allele was found to be significantly higher in patients compared to controls (p=0.002). In addition, we recognized a significant association between I/D polymorphism and respiratory-type panic disorder in patients. Carriers of the D allele also had an increased risk of respiratory type panic disorder patients (p=0.034). Moreover, the result of Spearman correlation analysis showed an association with ACE D allele and severity of panic disorder (p<0.001). Conclusion: We suggest that the I/D polymorphism of the ACE gene is associated with panic disorder and particularly respiratory-type panic disorder in patients. The I/D polymorphism of the ACE gene seems to influence therapeutic outcome in patients suffering from panic disorder. Our results indicate that ACE D allele is associated with the severity of panic disorder

Paraoxonase1 192 (PON1 192) Gene Polymorphism and Serum Paraoxonase Activity in Panic Disorder Patients

Background/Aim: Reactive oxygen species (ROS) are involved in the development of certain neuropsychiatric disorders. Paraoxonase 1 (PON1) activity has been suggested to be adversely related to oxidative stress in plasma. The purpose of the present study was to demonstrate the relationship between serum PON1 activity and PON1 192 polymorphism in panic disorder (PD). Materials and Methods: Fourty-two patients with PD and 46 healthy controls were included in this study. PON1 192 genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. PON1 activity was measured by spectrophotometric assay of p-nitrophenol production following the addition of paraoxon. Results: PON1 192 AA genotype and A allele in PD were significantly higher than in the control group, whereas the B allele was found to be significantly higher in the control group. Patients with panic disorder have lower PON1 activity than the control group. Conclusion: The PON1 192 AA genotype may increase the risk of PD depending on lipid peroxidation

Demographics of patients with heart failure who were over 80 years old and were admitted to the cardiology clinics in Turkey

WOS: 000468584300005PubMed ID: 30930455Objective: Heart failure (HF) has a high prevalence and mortality rate in elderly patients; however, there are few studies that have focused on patients older than 80 years. The aim of this study is to describe and compare the age-specific demographics and clinical features of Turkish elderly patients with HF who were admitted to cardiology clinics. Methods: The Epidemiology of Cardiovascular Disease in Elderly Turkish population (ELDER-TURK) study was conducted in 73 centers in Turkey, and it recruited a total of 5694 patients aged 65 years or older. In this study, the clinical profile of the patients who were aged 80 years or older and those between 65 and 79 years with HF were described and compared based on the ejection fraction (EF)-related classification: HFrEF and HFpEF (is considered as EF: >= 50%). Results: A total of 1098 patients (male, 47.5%; mean age, 83.5 +/- 3.1 years) aged 80 years and 4596 patients (male, 50.2 %; mean age, 71.1 +/- 4.31 years) aged 65-79 years were enrolled in this study. The prevalence of HF was 39.8% for patients who were >= 80 years and 27.1% for patients 65-79 years old. For patients aged >= 80 years with HF, the prevalence rate was 67% for hypertension (HT), 25.6% for diabetes mellitus (DM), 54.3% for coronary artery disease (CAD), and 42.3% for atrial fibrilation. Female proportion was lower in the HFrEF group (p=0.019). The prevalence of HT and DM was higher in the HFpEF group (p= 80 years with HFrEF (p<0.01). Conclusion: HF is common in elderly Turkish population, and its frequency increases significantly with age. Females, diabetics, and hypertensives are more likely to have HFpEF, whereas CAD patients are more likely to have HFrEF.Turkish Society of CardiologyThis study was supported by Turkish Society of Cardiology
