In Qatar, cardiovascular diseases are the leading causes of morbidity and mortality. Cardiovascular diseases can be prevented and controlled by modifying lifestyle risk behaviors. In this qualitative study, we investigate ways to increase participation in physical activity, and to promote a healthy diet, and nonsmoking behavior in Qatari women. Individual in-depth interviews were conducted with 50 Arabic women. Participation in physical activity, observing a healthy diet, and abstinence from smoking are desirable lifestyle practices among Qatari women. Social support networks, cultural values, religion, changing sociodemographic and economic conditions, heart disease, and a harsh climate affect the ability of these women to pursue a healthy lifestyle.

Cardiovascular diseases are the leading cause of mortality and morbidity globally. Similar to other Western and Gulf countries, the incidence of cardiovascular disease and coronary artery diseases such as acute myocardial infarction is rising rapidly in Qatar. Diabetes mellitus, smoking, and hypertension are the most common risk factors causing acute myocardial infarction, congestive heart failure, and stroke. Additionally, obesity resulting from physical inactivity and unhealthy diet can lead to metabolic changes and raise the risk of heart diseases. Studies show that these health problems can be prevented and/or controlled by modifying lifestyle risk behaviours related to physical activity, diet, and smoking habits. The ultimate goal of this study was to find ways to effectively promote cardiovascular/coronary artery disease prevention and management activities among Qatari women by exploring factors affecting the ways in which Qatari women (citizen and resident Arabic women) participate in physical activities, healthy diet and smoking. An exploratory qualitative research approach using a semi-structured questionnaire consisting of open-ended questions was used in this study. Study participants included 50 Qatari women, 30 years of age and over, having a confirmed diagnosis of coronary vascular disease /coronary artery diseases. Results showed that socio-cultural factors play a key role in Qatari women's decisions to participate in healthy lifestyles. Counselling and guidance for patients by health care providers, especially physicians, regarding smoking cessation, weight loss, and exercise should be key interventions to modify lifestyle behaviors among cardiac patients.

Background: Musculoskeletal manifestations are common in sickle cell disease (SCD). Vasoocclusive crisis can manifest acutely as joint and bone pain, osteomyelitis and/or arthritis. It can also lead to chronic bone aches, bone deformities, degenerative arthritis, pathological fractures, and osteoporosis. Hyperbaric oxygen (HBO) therapy is a mode of treatment in which Case Shier et al.: Short-Term Outcome and MRI Changes in Three Adult Patients with SCD and Aseptic ON after Treatment with HBO Therapy 366the patient is exposed to very high arterial and tissue oxygen pressure, during multiple sessions. It has been used as primary or adjunctive therapy for a variety of medical disorders, including necrotizing infection and sickle cell crisis. Case Report: In this case series, 3 patients with SCD and avascular necrosis were treated with 15-40 sessions of HBO and were assessed 6-12 months by MRI after treatment. They showed different clinical outcomes and MRI changes. Conclusion: We concluded that HBO can result in some subjective improvement, especially in early stages. Further studies on severe cases are needed.
