Aortic atresia with normally developed left ventricle in a young adult

Congenital aortic valve atresia is usually part of a developmental anomaly usually called ‘hypoplastic left-heart syndrome’. To the best of our knowledge, most reported cases of aortic atresia have been associated with hypoplasia of the ascending aorta, of the left ventricle, and of the mitral valve. We report a patient presenting with aortic atresia with a ventricular septal defect and a normally sized left ventricle. (Cardiol J 2011; 18, 3: 304–306

Demographic Characteristics and Personality Disorders in People With Gender Dysphoria in East Azerbaijan Province, Iran

Background: Gender identity is an important part of human identity. It is a personal conception of oneself as male or female. One of the major goals of treatment for individuals with Gender Dysphoria (GD) is to treat comorbid psychological and psychiatric disorders such as personality disorders. The present study aims to investigate demographic characteristics and personality disorders in people with GD seeking gender reassignment therapy in East Azerbaijan Province, Iran.Methods: In this descriptive cross-sectional study, study population consists of all patients with GD referred to the forensic medicine centers in East Azerbaijan province during 2016-2020, of whom 61 (21 males and 40 females) were selected using a convenience sampling method. Their age, gender, educational level, and marital status were recorded and their personality profile was assessed by the Millon Clinical Multiaxial Inventory–III.Results: The frequency (percentage) of Cluster A, B and C personality disorders in males were 0(0%), 9(50%) and 2(11.10%), while in females they were 1(5.56%), 4(22.40%), and 2(11.10%), respectively. The frequency (percentage) of antisocial, obsessive, borderline, avoidant, narcissistic, histrionic, and paranoid personality disorders in males were 4(22.2%), 2(11.10%), 3(16.67%), 0(0%), 0(0%), 2(11.10%), and 0(0%), while in females they were 4(22.20%), 1(5.56%), 3(16.67%), 1(5.56%), 1(5.56%), 2(11.10%), and 1(5.56%), respectively. The prevalence of different clusters (P=0.34) and types (P=0.18) of personality disorders was not significantly different between males and females. Conclusion: Personality disorders are comorbid with GD. They exist in one-third of patients with GD in East Azerbaijan Province. Personality disorders are significantly more prevalent in male patients with GD than in females

Quantity and Quality of Vision Using Tinted Filters in Patients with Low Vision Due to Diabetic Retinopathy.

[en] PURPOSE: To investigate the effect of tinted filters on visual acuity (VA), contrast sensitivity and patient satisfaction in diabetic retinopathy associated with low vision. METHODS: In a prospective study, 51 patients with diabetic retinopathy and low vision were assessed. We chose a simple random sampling method and used the patient's files for data collection. LogMAR notations were applied for assessing VA and a contrast sensitivity chart (CSV-1000) was employed for measuring contrast sensitivity. First, measurements were performed without tinted filters and then using them. Appropriate lenses were given to the patients for 2 days, and they were questioned about their satisfaction using them in different places. RESULTS: A total of 20 male and 31 female patients with mean age of 57.3 years participated in the study. With a 527 ± 10 nm filter, mean VA improved significantly (P ≤ 0.05). Using the 527 ± 10 nm and 511 ± 10 nm filters, mean contrast sensitivity was improved significantly at 3 and 6 cycles/degree frequencies (P < 0.05). The effect of other filters on VA and contrast sensitivity was not significant. Patient satisfaction rate was generally high. CONCLUSION: Tinted filters are able to rehabilitate low-vision patients due to diabetic retinopathy. The 527 ± 10 and 511 ± 10 nm wavelength filters improved contrast sensitivity and the 527 ± 10 nm filter improved VA to some extent. Further investigations are recommended to assess the effect of these filters in patients with other causes of low-vision

Investigating the Effect of Apparel Color Dimensions on Customer Purchase Intention: An Analysis on Customer Gender Differences

Objective: Colors as one of the most fundamental components of any product (especially apparel) have a significant impact on consumer behavior. These effects can be studied on various aspects, so that with a thorough analysis we can manufacture desirable apparel with appropriate color suited to the needs of customers. In this study, in order to fill the research gap, the effect of color on customer purchase intention is investigated and the difference between the views of men and women about each of the dimensions is analyzed. Methods: Statistical population consists of all store's customers at Setareh store in Shiraz in which we chose 279 individuals. Questionnaire validity is tested by two approaches including face and content methods while we conducted two methods to verify the reliability including Cronbach's alpha: 86%, and split half: 76%. Results: Findings showed that the most important factor among the others affecting customer purchase intention is customer color preferences while color norms does not affect customer purchase intention. Another findings reveals that only about the color norms, women and men have Different opinions. On the other hand, among the cultural, religious, friends and individual interest, individual interest factor is the most effective predictor of choosing a special color. Conclusion: Color, as a low-cost element in apparel products, plays an important role in customer decisions. If a special color is of high importance compare to other colors and it is of customer's interest, it will be preferred

Predictors of Postoperative Atrial Fibrillation after Coronary Artery Bypass Graft Surgery

Objectives The present study was aimed to identify the preoperative, intraoperative, and postoperative predictors of AF in a pure cohort of the patients with coronary artery disease who underwent CABG surgery. Methods Between November 2005 and May 2006, 302 consecutive patients were included in this prospective study. All the relevant clinical, electrocardiographic, echocardiographic, and laboratory data were gathered in the included patients and they were also monitored for development of post-CABG AF.Results Postoperative AF occurred in 46 (15%) of patients. By univariate analysis, older age, P-wave abnormality in ECG, presence of mitral regurgitation, larger left atrium (LA), left main coronary artery involvement, failure to graft right coronary artery (RCA), and adrenergic use in ICU were significantly associated with occurrence of post-CABG AF (all P< 0.05). However, in the logistic regression model, age (OR: 1.067, 95%CI: 1.02-1.116, P=0.005), LA dimension (OR: 1.102, 95%CI: 1.017-1.1936, P=0.017), P-wave morphology (OR: 12.07, 95%CI: 3.35-48.22, P=0.0001), failure to graft RCA (OR: 3.57, 95%CI: 1.20-10.64, P=0.022), and postoperative adrenergic use (OR: 0.35, 95%CI: 0.13-0.93, P=0.036) remained independently predictive of postoperative AF.Conclusion The present study suggested that age, P-wave morphology, LA dimension, failure to graft right coronary artery, and postoperative adrenergic use were independent predictors of post-CABG AF. Therefore, clinical data, ECG and echocardiography may be useful in preoperative risk stratification of the surgical patients for the occurrence of post-CABG A

Features of Three- and Four-Part Proximal Humeral Fractures and Outcome of Internal Fixation Using the Philos® Locking Plate

Background: Proximal humeral fractures are among common types of fractures and remain a challenging issue for surgical management. This study aimed to assess the clinical outcomes and complication rates of three- vs. four-part proximal humeral fractures, treated with internal fixation using the Philos® plate.Material and Methods: In this cohort study, a total of 30 consecutive patients with three-part or four-part proximal humeral fractures based on the Neer classification were included. Surgical treatment was performed with open reduction and internal fixation using the Philos® plate. The constant score was evaluated 6 months later in follow-up. The P&lt;0.05 was considered significant.Results: Four-part fractures were mainly caused by trauma from above, while insults of opposite direction were responsible for more than half of 3 part fractures (P=0.01). Open fractures were only observed in patients with a four-part fracture (P=0.018). No significant differences were noticed regarding gender, cause, and side of the fracture.The presence of other fractures, fracture of the implant, reduction loss, avascular necrosis (AVN) of humerus head, rotator cuff injury, and revision surgery were significantly higher in patients with four-part fractures.The mean constant score was 81.40±11.61 and 65.09±16.09 for three-part and four-part fractures, respectively (P=0.006).Conclusion: Open reduction and internal fixation with Philos® plate yield acceptable results in both types of fractures, however, the prognosis of this intervention is poorer four-part fractures

Cicer arietinum in the Treatment of Small Renal Stones: a Double-Blind, Randomized and Placebo-Controlled Trial

Background and objectives: Urolithiasis is a common urological disorder. Based on the Persian medicine literatures, Cicer arietinum has a potential to dissolve renal stones. This study was designed to assess the efficacy and safety of Cicer arietinum in patients with renal stone. Methods: The extract of C. arietinum seeds was spray dried. A randomized, double blind, placebo-controlled study was conducted on 74 patients with 6-10 mm renal stones in ultrasonography. Patients were randomly assigned to take 330 mg of C. arietinum extract or placebo capsules three times a day for 30 days. Complete stone dissolution and the change in stone size during the trial was evaluated by ultrasonography. To assess the efficacy and safety of C. arietinum, blood and urine biochemical parameters were checked at baseline and after the intervention. Results: In the C. arietinum group, complete stone dissolution occurred in 9 (23.7%) patients and reduce in stone size was observed in 17 (44.7%) patients while no response to treatment was observed in placebo group. The mean stone size was reduced from 7.15 ± 1.34 mm to 4.28 ± 3.09 mm in the C. arietinum group (p Conclusion: Cicer arietinum extract could be an effective and safe treatment option for patients with 6-10 mm renal stones

A Novel Bone Substitute with High Bioactivity, Strength, and Porosity for Repairing Large and Load-Bearing Bone Defects.

Achieving adequate healing in large or load-bearing bone defects is highly challenging even with surgical intervention. The clinical standard of repairing bone defects using autografts or allografts has many drawbacks. A bioactive ceramic scaffold, strontium-hardystonite-gahnite or "Sr-HT-Gahnite" (a multi-component, calcium silicate-based ceramic) is developed, which when 3D-printed combines high strength with outstanding bone regeneration ability. In this study, the performance of purely synthetic, 3D-printed Sr-HT-Gahnite scaffolds is assessed in repairing large and load-bearing bone defects. The scaffolds are implanted into critical-sized segmental defects in sheep tibia for 3 and 12 months, with bone autografts used for comparison. The scaffolds induce substantial bone formation and defect bridging after 12 months, as indicated by X-ray, micro-computed tomography, and histological and biomechanical analyses. Detailed analysis of the bone-scaffold interface using focused ion beam scanning electron microscopy and multiphoton microscopy shows scaffold degradation and maturation of the newly formed bone. In silico modeling of strain energy distribution in the scaffolds reveal the importance of surgical fixation and mechanical loading on long-term bone regeneration. The clinical application of 3D-printed Sr-HT-Gahnite scaffolds as a synthetic bone substitute can potentially improve the repair of challenging bone defects and overcome the limitations of bone graft transplantation

Exploratory analysis of the feeding program delivered by a Non- Government Organisation (NGO) in the Philippines
