Health (Health) , 2016, DOI: 10.4236/health.2016.81004
Abstract: Background: The hospital is a scientific organization that despite much progress, today, is also dependent on manpower. One of the main requirements for the proper functioning of manpower is that through learning, they be updated in terms of knowledge. Thus, the aim of this study was to determine the level of Organizational Learning Capability in hospitals in Bandar Abbas City—Iran. Methods: In 2014, this descriptive-analytic study was conducted in hospitals in Bandar Abbas City. The data was collected through the Gomez questionnaire for organizational learning from 290 employees of hospitals. Data analysis was done using software SPSS V.20 and by the Mann-Whitney U test and the Kruskal-Wallis test. Results: Organizational Learning Capability in governmental, private and social security hospitals were 0.31 ± 53.06, 9.38 ± 47.38 and 0.27 ± 50.74, respectively. The results of the Kruskal-Wallis test showed that the relationship between the variables of employment status (p = 0.034), occupational categories (p = 0.043), and type of ownership (p = 0.02), was significant with the organizational learning capability but such a significant relationship was not observed in terms of age, educational level and employment status. The results of the Mann- Whitney U-test indicated a significant association between marital status (p = 0.029) and type of hospital (p = 0.049) with the organizational learning capability. Conclusion: Need to up-to-dating of staff’s knowledge has made undeniable the role of organizational learning. According to the results, managers have to provide conditions for improving the status quo through promoting or-ganizational learning and extend the ability of the organization for growth and progress.

Health (Health) , 2015, DOI: 10.4236/health.2015.73035
Abstract: The rate of maternal mortality due to complications of pregnancy and delivery is one of the most significant indicators showing the development state of countries. The purpose of the present study is to assess important indicators of maternal health and predisposing factors of maternal mortality in Tehran province from 2008 to 2011. The present study is a case-control one. All mothers who had lost their life (n = 113) were selected through census and survived mothers (n = 327) through randomized stratified sampling. Statistical analysis was performed using SPSS V.22, X2 test, Fishers exact test and Logistic regression. The rate of maternal mortality was the highest (29.2%) in 2009 and the lowest (20.4%) in 2011. Variables type of maternity hospital (P-value = 0.036), maternal education (P-value < 0.001), husband’s education (P-value < 0.001) had a significant relation to maternal mortality. Logistic regression analysis showed that there is a relationship between the education level of the husband and maternal mortality. Considering the factors affecting maternal mortality, promoting hospital services, improving skills and knowledge of doctors, midwives and nurses and strengthening educational programs for the illiterate are the most effective measures to reduce maternal mortality.

Abstract: The purpose of this study was to evaluate the status of Kurdistan University of Medical Sciences regarding international standards of in-service training and Staff Qualifications and Education (SQE). This is an applied, descriptive-analytical, and cross-sectional study; it is performed by two questionnaires of “SQE standards” and “measurable standards of SQE” in 10 hospitals affiliated to Kurdistan University of Medical Science. Validity of the questionnaire “SQE standards” was confirmed by Cronbach’s alpha 0.87 and the questionnaire “measurable standards of SQE” 0.88. Analysis was done using the software SPSS v.18 and Kruskal-Wallis, Mann-Whitney tests and Error bar chart. A total of 300 questionnaires were distributed and 209 questionnaires were collected (response rate = 69.6%). The highest average score of SQE standards was related to Tohid Hospital (148.8) and the lowest score to Sina hospital (137.5). The mean scores were close to each other (137.5 to 148.8), but standard deviation of scores had great differences that the highest standard deviation (SD) was in Besaat Hospital (30.7). Functionality of SQE standards in hospitals under study was confirmed (57.5% to 94%) and current status in the hospitals under study for different areas was assessed as above average (79.6%).

Abstract: Background The present study was conducted to investigate the possible outcome of interaction between endothelial nitric oxide (NOS3) G894T and cholesteryl ester transfer TaqIB variants on the risk of coronary artery disease (CAD) and type 2 diabetes mellitus (T2DM). The sample included a total of 207 CAD patients (102 CAD patients with T2DM and 105 CAD patients without T2DM). There were also 101 patients with T2DM and 92 age- and sex-matched healthy individuals as controls. All study participants were from Western Iran. The sample was genotyped by polymerase chain reaction-restriction fragment length polymorphism. Results The presence of NOS3 T allele was not associated with the risk of CAD or T2DM, and the CETP B1 allele was only significantly associated with the increased risk of CAD in total CAD patients (odds ratio (OR) = 5.1, p = 0.019). However, the concomitant presence of both CETP B1 and NOS3 T alleles significantly increased the risk of CAD in total CAD patients (OR = 18.1, p < 0.001), in CAD patients without T2DM (OR = 27.1, p = 0.03), and in CAD patients with T2DM (OR = 13.5, p = 0.002). Also, the presence of both alleles increased the risk of T2DM (OR = 12, p = 0.004). Conclusions Our findings, for the first time, indicate that NOS3 T allele strongly interacts with CETP B1 allele to augment the risk of CAD and T2DM in the population of Western Iran.
Target Points in Trastuzumab Resistance
Sahar Shojaei,Mossa Gardaneh,Abbas Rahimi Shamabadi
International Journal of Breast Cancer , 2012, DOI: 10.1155/2012/761917
Abstract: Epidermal growth factor (EGF) family of receptors is involved in cell growth and differentiation. The human EGF2 (HER2) lacks natural ligands, and correlation between HER2 levels and carcinogenesis makes the receptor an ideal candidate for targeted therapy in breast cancer. Trastuzumab is a humanized antibody applied against HER2-positive breast tumors in clinic. Metastatic tumors respond well to trastuzumab therapy for the first year, but development of antibody resistance helps the tumors to regrow allowing the disease to progress. Trastuzumab resistance is shaped via a range of intracellular signaling pathways that are interconnected and share in key effector molecules. Identification of a common node central to these resistance pathways could provide an ultimate solution for trastuzumab resistance in breast and other cancers. 1. Introduction Breast cancer (BC) originates from the epithelial cells of the breast tissue that line the terminal duct lobular unit. BC is the most common cancer type that affects world population. More than 180,000 new cases of BC were diagnosed in 2008 in the United States alone [1]. Over 40,000 of these diagnosed cases resulted in death, mostly in women [1]. BC in women is the most commonly diagnosed cancer that accounts for 26% of all new cancer cases [2]. Well-known growth signaling pathways contribute to generation and progression of BC among other cancer types by promoting cell growth and proliferation [3]. These signaling pathways are promoted by a number of membrane-bound and intracellular receptors. The gene expression and biological activities of these receptors may have great impact on BC tumor initiation, progression, relapse, and prevention or treatment. Estrogen receptor (ER), progesterone receptor (PR), rearranged during transfection (RET), and human epidermal growth factor 2 (HER2) are the main membrane-bound receptors playing key roles in BC. Hormone therapy is directed against ER that is expressed in 70% of BC tumors. Antibody therapy, on the other hand, was initiated with development of trastuzumab (TZMB) that specifically targets HER2 in 20 to 30% of BC cases where HER2 is strongly present. Resistance to hormone therapy and TZMB therapy are two major hurdles in current clinical BC therapy. In this paper, we will focus on the main causative sources of TZMB therapy and recent developments in exploration of key molecules that hold promise for eradication of this resistance. 2. HER2 Receptor The HER/EGF family of receptors consists of four cell-surface receptors named HER1 (erbB1), HER2 (erbB2), HER3 (erbB3),

Abstract: In this study, headspace solid phase microextraction (HS-SPME) followed by gas chromatography using electron capture detection system (GC-ECD) were developed for the determination of chloraacetanilide (butachlor) and chlorpyrifos presented in biological samples. Different parameters affecting the extraction procedure were optimized including extraction time (30 minutes), extraction temperature (80°C), sample volume (3 mL), sample pH (2), added NaCl (0.3 gram) and sample stirring rate (400 rpm). Different concentrations of 1 - 100 ng/ml were applied for butachlor and a linear calibration curve was obtained. Furthermore, a similar linearity was obtained for chlorpyrifos, using a concentration range of 1 - 250 ng/ml. The limit of detection (LOD) obtained for butachlor and chlorpyrifos were 0.088 and 0.53 ng/ml respectively. The optimized methods for both compounds were validated using two concentrations of 25 and 50 ng/ml in spiked urine samples. Obtained recoveries of spiked urine samples were 83.06% - 99.8% with RSD of lower than 11%. Optimized technique was simple, inexpensive, solvent free and fast in comparison with other conventional methods and had compatibility with the chromatographic analytical system. This method offers low detection limits to analyze pesticides in urine samples that are very important in the exposure monitoring in occupational health.
