[ Comparison for estimating aerobic capacity [VO2max] Based on Subjective perception and physiology among nursing staff]

Background and aim: In order to establish appropriateness between labor and Human, aerobic capacity can be used. The methods which were used in physical labor are mental and physiological assessments. Subjective symptoms of fatigue during physical work are assessed with the Borg scale [RPE] and physiological with heart rate as well. This study aimed to compare the estimation of aerobic capacity [vo2max] with mental conception and physiology among male nurses in one of Tehran's hospitals.

Method: The present study was a cross – sectional analysis. In this study a number of male nurses have participated randomly and by the means of ergo meter were assessed according to Strand protocol. Aerobic capacity was determined by the formula ACSM. Meanwhile at the end of each minute, the intensity of perceived effort [RPE], as well as heart rate are calculated and recorded.

Result: Statistical analysis showed that between aerobic capacity and RPE are significant relationship [P<0.005], [r=-0.84]. And according to the results relationship of heart rate with aerobic capacity has more correlation [P<0.005], [r=-0.9].Therefore the regression analysis of quadratic equation showed that there is a significant relationship between aerobic capacity and heart rate.

Conclusion:The results showed that the subjective assessments of individuals with aerobic capacity are high and there has been more relation between physiological assessment and aerobic capacity. In other words, a more reliable measure of heart rate in the aerobic capacity is estimated, so we can use heart rate as a physiological factor used to estimate aerobic capacity of individuals. The monitoring is done to individuals assigned to work with physical capacity to be deployed

effect of volunteer health workers educational program on the basis of BASNEF model on promotion of their practices about cutaneous Leishmaniasis

Since, a few study have been done using community education related to cutaneous leishmaniasis [CL] prevention, this study was done to assess the effect of educational program basis on BASNEF Model for promoting Volunteer Health Workers [VHWs] educational practices about CL prevention. In this prospective quasi-experimental study, 60 VHWs who resident in endemic area of CL in Yazd in 2009 were selected through cluster sampling method and randomly divided in two groups [experimental and control group]. Data were collected before and 3 months after educational intervention by using reliable and valid questionnaires and analyzed. The mean score of knowledge and BASNEF Model components such as attitude, behavioral intention, enabling factors and practice as well as subjective norms [family, friends, neighbors, local trusted people, local therapist, local mullah, health workers and physician] increase significantly [p<0.05] 3 months after the intervention program among experimental group comparing to control group. This study was confirmed effectiveness of the training VHWs by using educational program basis on BASNEF model related to CL prevention program

role of maternal thyroid stimulating hormone receptor blocking antibodies in the etiology of congenital hypothyroidism in Isfahan, Iran

Considering the role of maternal thyroid stimulating hormone [TSH] receptor blocking antibody [TRAb] in the etiology of congenital hypothyroidism [CH], this study aimed to determine TRAb among patients with CH in Isfahan, Iran. In this case-control study, patients with CH and their mothers were compared with a group of healthy neonates and their mothers. Venous blood samples were obtained for measurement of TRAb using enzyme-linked immunosorbent assay [ELISA] method among mothers and their neonates. TSH of mothers was also determined. The case group consisted of 65 patients with CH and their mothers; controls were 148 healthy neonates and their mothers. The prevalence of positive TRAb in patients with CH and their mothers was higher than in the control group [81.5% vs. 1.3% in mothers and 80% vs. 0% in neonates, respectively, P<0.05]. The relationship between the TRAb and occurrence of CH was significant [P<0.05], whereas the corresponding figure was not significant for TRAb and the level of maternal and neonatal TSH in case and control groups [P>0.05]. It seems that autoimmunity has an important role in the etiology of CH. Further studies are necessary to determine other autoantibodies in CH patients

relationship of hemoglobin and hematocrit in the first and second half of pregnancy with pregnancy outcome

Considering the relationship of low and high levels of hemoglobin and hematocrit with some pregnancy complications, we decided to study their relationship with pregnancy outcome. This study also aimed to investigate the changes in hemoglobin and hematocrit values during the second and first half of pregnancy and its relationship with pregnancy outcome. In a prospective cohort study, 520 Iranian pregnant women, aged 15 to 45 years that were supported by health centers in Isfahan, Iran, were recruited using quota sampling method. Exclusion criteria comprised of 36 conditions that were related to the maternal and infant outcomes. Hemoglobin and hematocrit were measured in eligible mothers during the 6[th]- 11[th] weeks and 26[th]-30[th] weeks of pregnancy. They were monitored until delivery and the data regarding their pregnancy outcome were collected. Low levels of hemoglobin during the first half of pregnancy was associated with preeclampsia [p = 0.024]. Moreover, low levels of hemoglobin during the second half of pregnancy was associated with the risk of preterm premature rupture of membranes [p = 0.01]. In addition, mothers with lower blood dilution, as a physiological process during pregnancy, were more prone to preeclampsia [p = 0.04]. Hemoglobin levels in the first and second half of pregnancy can predict preeclampsia and premature preterm rupture of membranes. Increased hematocrit levels in the second half of pregnancy or lack of reduction of hematocrit levels in the second half compared to the first half can estimate preeclampsia.

investigation on the effect of gastric cancer education based on Health Belief Model on knowledge, attitude and nutritional practice of housewives

Planning the educational programs and informing people regarding the prevention of widespread diseases like cancers is necessary. With regard to high mortality rate of gastric cancer, the present study was conducted to define the effect of education based on Health Belief Model on knowledge, attitude and nutritional practice of homemakers. In this interventional study, 84 housewives were randomly divided into two groups. The study group underwent seven sessions of education based on Health Belief Model. Control group did not receive the education. Both groups filled valid and reliable questionnaires before and 2 months after program. There was no significant difference between the two groups in demographic characteristics. While mean scores of knowledge, attitude and practice were not significantly different before education, the intervention group showed significantly higher scores after education [p < 0.001]. Health education based on Health Belief Model increases the knowledge and improves the attitudes and practices of housewives regarding prevention of the gastric cancer. It seems essential to development this sort of educational programs.

study on work ability index and physical work capacity on the base of fax equation vo[2] max in male nursing hospital staff in Isfahan, Iran

The purpose of this research is to establish the ability of employees by work ability index [WAI], physical work capacity [PWC], and finding the correlation between them. Establishing the PWC index with attention to WAI values for the purpose of saving in costs and time of PWC measurements is another aim of this project. The present research is an analytic cross-sectional and one-trail study. The study population consists of 228 randomly selected registered nurses from hospitals in Isfahan [Iran]. The WAI and PWC were established through WAI questionnaire and Fax equation and by using ergometer bicycle, respectively. The resulting data were analyzed using SPSS 16 software. Average WAI and PWC among the study population were 38.25 +/- 4.4 and 4.45 +/- 0.7, respectively. Pearson test results showed no significant correlation between PWC and WAI in different age groups [r=0.3 and P>0.05]. Multiple linear regression analysis showed that the variables of age and diagnosed diseases were the most effective factors of WAI [beta=0.18 and P>0.05]. Pearson test revealed a significant correlation between the number of diagnosed diseases and PWC index in age groups of 40-49 years. Average WAI in this research, like other studies on similar jobs is in the acceptable level of >36. Work ability index and PWC index in different age groups did not show a significant correlation and this suggests that there are essential discrepancies in work ability evaluations made by each index and it is not possible to predict PWC index using WAI values. Given the PWC results and the level of nursing staff's activity [low, medium] the WAI is a suitable instrument to establish the professionals' abilities. This study revealed that 27.6% of individuals were subject to medium-low work ability risk [WAI<37], which was 1.8 times that of Finland's professional health Institute, which could be caused by shift working and increased working hours

effect of educational program based on BASNEF model for eye care in non-insulin dependent diabetic patients

The purpose of this study was to determine the effects of educational program based on the BASNEF [Belief, Attitude, Subjective Norm, and Enabling Factors] Model on eye care among patients with insulin independent diabetes mellitus in Shiraz City, Fars Province, Iran. We enrolled 100 patients with non-insulin independent diabetes mellitus [Type II] fulfilling the inclusion criteria of this experimental study. The participants were randomly divided into two groups, one experimental, and one control group. All groups completed the questionnaires based on the BASNEF Model, a checklist related to patient's practice including patients' HbA1c and FBS levels, the pre-test results of an ophthalmologist's eyes examination and the results of three months follow-up. The experimental group participated in eight educational sessions during the interventional. The data analysis used including chi square-test, t-test, and ANOVA. The knowledge and all BASNEF Model components were significantly increased in the experimental group compared to the control group after intervention. In addition, behavioral eye care, such as physical activities, regular taking medicine, having eye examination, FBS checking, having appropriate diet, HbA1c level, and fasting blood sugar levels improved significantly among the experimental group compared to the control group. Applying the BASNEF Model is very effective for developing an educational program for diabetic patients, in order to control their blood sugar and enhancing behavioral eye care. Besides such programs, follow up education on controlling and monitoring is highly recommended

Study of the effects of behavioral intention model education on reducing the cesarean rate among pregnant women of Khomeiny-Shahr, Isfahan, in 2006

The cesarean section rate is very high and is increasing in most countries including Iran. Being a major surgery, the cesarean section may have dangerous side effects and even can be rarely fetal. During recent years, in most developed countries there have been many attempts to reduce the cesarean rate using education and other interfering methods. In our country it seems that the efforts with this regard have not been significant. The goal of the present study was to evaluate the effects of Behavioral Intention Model [BIM] education on reducing the cesarean rate among pregnant women. In this interventional study, 140 women at their first-time pregnancy and in 3rd trimester, where chosen in the winter of 2005, using simple random sampling method; they were divided into case and control groups. After pretest using a questionnaire in both groups, BIM was employed for the test group, followed by a post test performance in both groups. The collected data were analyzed by T-paired, independent T and chi-square methods. The results showed significant differences between case and control groups in the level of knowledge, evaluation of results, attitude and behaviors [p< 0.001]. According to the results, it can be concluded that BIM is effective on increasing or improving the knowledge, evaluation of results, attitude, strengthening the intention and behavior of the pregnant women. It is, therefore, suggested to use this method and other systematic education for pregnant women to decrease the rate of unnecessary cesarean
