Organizational culture and the organizational commitment; Correlational study in hospital staffs

Organizations need the committed manpower to provide effectiveness and progress which is an important factor in order to achieve organizational goals. According to this, organizational culture increases employees commitment in the organization by their accepted norms and values. Actually, the organization environment & its prevailing culture, affects on the organizational commitment of staff. This study was conducted to assess relationship between the organizational culture and the organizational commitment among staff of elected hospirals in Tehran University of Medical Sciences. This descriptive study accomplished at 2013. The study population was hospitals affiliated to Tehran University of Medical Sciences included the two hospitals �Vali Asr� & �farabi�. Also in hospitals, study populations were all hospital staffs (Administrative and Clinical). Data collection was done using a three parts questionnaire including: the first one contains background information, the second part consists of questions related to organizational culture based on Denison model and the third part includes questions related to organizational Commitment based on Porter model. Validity and reliability were confirmed through getting the opinions of experts and using Cronbach�s alpha. Data analysis was done by SPSS software using Pearson correlation test and the test �t� to determine the relation between the areas of culture and commitment to the type of hospitals. In organizational culture, maximum average & standard deviation has been seen in professional identity (4.74±1.38). Except for the two dimentions of conflict & communication patterns, a significant relation between the organizational culture dimentions and two hospitalas was seen. Also, in the organizational commitment, the maximum average & standard deviation was seen in continuous commitment scope. Overally, average & standard deviation (3.18±0.76) has been obtained for organizational commitment component; also there was significant relation between the emotional commitment dimention & the type of the hospital. This relationship wasn�t meaningful in another dimentions. Except for the conflict dimension, there was significant correlations between the organizational culture dimension& the organizational commitment (p<0.05). Also, this correlation was between the organizational culture and the organizational commitment (r=0.552) Designing an appropriate and justified "reward mechanism" and development of "teamwork" skills between employees can increase their organizational commitment positively and improve hospital performances. © 2015, Canadian Center of Science and Education.

Prevalence rate of laboratory defined aspirin resistance in cardiovascular disease patients: A systematic review and meta-analysis

Background: Cardiovascular disease (CVD) is the first cause of mortality worldwide, with all the healthcare systems facing this very challenging issue. Aspirin continues to be the major gold-standard treatment worldwide in the prevention of thrombotic disease in patients with CVD, even though not all individuals respond to antiplatelet therapy in a similar way, being resistant to aspirin. The aim of this study was to determine the prevalence of laboratory defined aspirin resistance in CVD patients worldwide. Methods: Relevant articles were identified through searching EMBASE, PubMed/ MEDLINE, ISI /Web of Science, Scopus, and the Cochrane Library, from January 2000 to February 2018. The methodological quality of the included studies was critically appraised using the Newcastle-Ottawa scale. The pooled prevalence of laboratory defined aspirin resistance was computed using the Der Simonian-Laird random-effect model. Results: We included 65 studies, with a total of 10,729 patients. The overall prevalence of laboratory defined aspirin resistance in CVD patients was 24.7 (95%CI 21.4-28.4. Women were found to be at increased risk of laboratory defined aspirin resistance compared to men, with an odds ratio of 1.16 95%CI 0.87-1.54 Conclusion: Doctors and healthcare providers should pay special attention to aspirin resistance since lack of awareness could cause problems and increase mortality in these patients, if not properly treated with higher aspirin doses. © 2020 Caspian Journal of Internal Medicine.

The prevalence of migraine in Iran: A systematic review and meta-analysis

Context: Migraine is a major dilemma and problem which affects public health and results to reduced quality of life. This study aimed to determine the prevalence of migraine in Iran. Evidence Acquisition: A systematic search was conducted using Pub Med,Web of Science,Embase,Scopus,Ovid,Google Scholar,as well as Iranian databases including: MagIran,IranMedex and Scientific Information Databank,from 2000 to November,2015. The Der-Simonian/Laird�s random-effects model,with a 95 confidence intervalwasemployed to estimate the overall pooled prevalence. Heterogeneity was investigated using subgroup analysis based on sample size and time of study. Results: Thirty studies comprising 33,873 participants met the inclusion criteria for the analysis. The overall prevalence of migraine in Iran was 14 (95 CI,12 to 17),respectively. The overall prevalence was (8; 95 CI 6 to 11) according to the international classification of headache disorders (ICHD-1),(17; 95 CI 13 to 21) according to ICHD-2,and (18; 95 CI 7 to 30) according to the other questionnaire for migraine screener (ID Migraine),respectively. Meta-regression demonstrated that the prevalence of migraine increased by year of publication and decreased by sample size. Conclusions: The prevalence of migraine in Iran,which was estimated as 14,was similar or even higher than that reported worldwide. Migraine can have impact on the economic productivity of any country; therefore it is necessary to educate people on the early detection and the discovery of an effective treatment of migraine. More thorough review of further studies in this field is recommended. © 2016,Iranian Red Crescent Medical Journal

Prevalence rate of hepatitis B virus in pregnancy: Implications from a systematic review and meta-analysis of studies published from 2000 to 2016

Background: Hepatitis B Virus (HBV) is one of the most serious infectious diseases and represents a major global health issue worldwide. It can be transmitted vertically and horizontally through contact with infected blood or body fluids. More attention to HBV infection in pregnancy is needed due to high risk of chronicity when transmitted to infants during delivery. Objectives: A comprehensive review of the HBV prevalence rate in pregnant females taking into account different geographical areas and socio-economic status is still lacking. This would be of crucial importance for HBV prevention and control programs. As such, this systematic review and meta-analysis was conducted focusing on HBV prevalence rate in pregnant females from different parts of the world. Methods: Different electronic databases, including Embase, PubMed/MEDLINE, Scopus, and ISI/Web of Science were searched from January 1st 2000 to July 31st 2016, using relevant keywords, such as �prevalence� or �seroprevalence� or �epidemiology� and �pregnancy� or �pregnant� or �antenatal� in combination with �hepatitis B virus� or �HBV� with no language restrictions. The study protocol of this systematic review was deposited at the �International Prospective Register of Systematic Reviews� and registered as CRD42016041985. Results: After scrutinizing all the extant scholarly literature from 2000 to 2016, this study found 222 relevant articles. The overall HBV prevalence rate in pregnant females worldwide was estimated using a random-effect model, giving a value of 3 (95 confidence interval or CI 2 - 4). Heterogeneity between studies was significantly high (I2 = 99.9, P &lt; 0.0001). The clinical and epidemiological burden was higher in developing countries. Conclusions: This suggests that despite the recent scientific advancements and the clinical progress that has occurred in anti-viral therapy, HBV still represents a major issue worldwide, especially in underdeveloped countries. The key strategies for preventing transmission from pregnant females to their fetuses are through early birth dose and infant vaccination, as well as by the use of hepatitis B immunoglobulin (HBIG) and the screening and diagnosis of mothers at high risk and the subsequent use of anti-viral agents during pregnancy in order to reduce maternal DNA concentrations down to undetectable concentrations. Health authorities should effectively implement these approaches to better control HBV in pregnancy. © 2018, Hepatitis Monthly
