ABSTRACT
The thesis provides an opportunity for the students to conduct a study and thus to get ready for future research cases. Medical students have faced numerous challenges for their thesis including the selection of the subject, the study approval, equipment and supplies shortage and etc. We have conducted the present study to determine the attitude of medical interns towards the challenges they encounter when performing their thesis study in Mazandran Medial Sciences University in 2010. This is a descriptive study on 96 medical interns of Medical School. Data were collected using a self-administered questionnaire about demographic characteristics, the students' status, thesis and their attitude towards challenges they encountered when conducting it. 40.6% of the medical interns in our study confirmed the necessity of thesis for general medicine program. The students [44.8% of the study units] agreed with the thesis being necessary for a general medicine program; it is best to offer it during the final 2-3 years of the program. The most important challenges were lengthy bureaucratic procedure and lack of organization among different levels of decision-making in order to approve the thesis. 34.4% of the students relatively believed that the supervising and consulting professors spend enough time on guiding and supervising the students. It is necessary to reconsider the onset, the approval procedure, as well as the regular supervision of its progress
ABSTRACT
Prevalence of over weight and obesity is increasing in the world. Those over weight are more susceptible to cardiovascular diseases than other individual's. Studies indicate that body fat distribution has a determining role in the identification of risk factors. Also, the relation between BMI, cardiac ischemic pains and exercise test condition in such patients, is in need further investigation. The aim of this study was to determine the relation between BMI with exercise tolerance test in patients with cardiac ischemic pains, who were referred to the Cardiac Center of Mazandaran Province, in Sari Township. In this case control study considering the BMI in ischemic patients, 65 were selected as case and 65 persons as control using Tread mill and according to Bruce Protocol, results and tolerance test time was recorded. Independent T test was used for comparison of quantitative indexes mean, while x[2] test using SPSS software was used for comparison of the ratio of persons with the qualitative features. Data indicated mean weight of 57.1 kg and height of 1.64m in the case group. Also, 58.5% had history of hyperlipidemia [Cholesterol higher than 200mg/dl] and 78.8% with history of blood sugar [higher than 120mg/dl [P<0.001]. Even 63.6% had hypertension of 140/90 mm Hg. Our findings showed that BMI in the case and control groups were [26.95 +/- 3.94] and [25.95 +/- 3.49] respectively. Moreover, a significant relationship between high BMI with cardiac ischemic pains and exercise tolerance test [P<0.001] were demonstrated. Cardiac ischemic pains in individuals with high BMI is common. Exercise tolerance test as one of the non invasive and less expensive procedures, can be an indicator of cardiac ischemic disease
