Investigation of depression prevalence in slow coronary artery patients

Introduction: There is limited information about the association between Coronary Slow Flow (CSF) phenomenon and depression. This study aimed to investigate the prevalence of depression in slow coronary artery patients in compression of patients with normal coronary artery and those with significant coronary stenosis under angiography at Shafa hospital of Kerman in 2018. Materials and Methods: This was a cross-sectional study that was performed on 180 people. All participants were divided into three groups (60 patients with CSF diagnosed by elective Coronary Angiography (CAG), 60 people with Coronary Normal Flow (CNF), and 60 patients with significant coronary artery diseases (CAD) who were referred to Shafa hospital of Kerman in 2018. The data collection tool was a questionnaire that included two parts: demographic information and Beck Depression Scale. Data were analyzed by using SPSS 24 software. Results: The results showed that 55 % of the sample were male and the incidence of mild, moderate, and severe depression is significantly higher among patients with CSF in compromising with normal and coronary stenosis group (P <0.0001). Conclusion: Due to the significant association between depression and CSF, it is necessary for people with cardiovascular disease to be screened for psychiatric problems

Determining the location of hip joint centre: application of a conchoid's shape to the acetabular cartilage surface of magnetic resonance images

Preoperative planning, or intraoperative navigation of hip surgery, including joint-preserving procedures such as osteotomy or joint-replacing procedures such as total arthroplasty, needs to be performed with a high degree of accuracy to ensure a successful outcome. The ability to precisely localise the hip joint rotation centre may prove to be very useful in this context. The human hip joint has been shown to be a conchoid shape, and therefore the accurate location of the hip joint centre (HJC) cannot be computed simply as the centre of a sphere. This study describes a method for determining the HJC by applying a conchoid shape to the acetabular cartilage surface of magnetic resonance images, in order to increase the accuracy of the HJC location which had previously been calculated by a functional method using reconstructed three-dimensional surface bony models. By approximating a conchoid shape to the acetabulum, it was possible to compensate for HJC calculation errors
