The Agreement Rate about Unintended Pregnancy and Its Relationship with Postpartum Depression in Parents of Preterm and Term Infants  [PDF]
Maryam Ghorbani, Mahrokh Dolatian, Jamal Shams, Hamid Alavi-Majd
Open Journal of Nursing (OJN) , 2015, DOI: 10.4236/ojn.2015.59084
Abstract: Introduction: Postpartum depression (PPD) affects women’s health and self-confidence, and infant’s social, emotional, cognitive and even physical development. Studies show that parents of preterm infants frequently experience symptoms of depression and anxiety. Women with unintended pregnancy are subjected to more risk of depression than women with planned pregnancy. Unintended pregnancy may lead to increased maternal exposure to psychosocial stressors, reduced social support by the spouse, increased levels of depressive symptoms and decreased life satisfaction. Findings: No significant difference was observed between term and preterm infants’ mothers (p = 0.85) in terms of postpartum depression. However, two groups of fathers in terms of depression showed a significant difference (p = 0.045). McNemar’s test showed that parents of term infants (K = 0.322, p = 0.077), and parents of preterm infants (k = 0.17, p = 0.144) agreed with each other on unintended pregnancy. Conclusion: Fathers of preterm infants are at higher risk for mental disorders than fathers of term infants and they need more attention in future studies.

Knowledge & Health Journal , 2008,
Abstract: Introduction: Interest to education is the one of the most important factors for learning and is formed from motivation and curiosity. It is well known the person who is motivated, insists for progress and gaining knowledge more and more. Therefore, learners interest in their career is one of the optimums in educational programs improvement and ultimately it result in their reproductively and take on responsibility so lots of attention should be given to this fact. The purpose of this study was to identify midwifery students, interest to their career at three medical sciences universities of Tehran in 2006. Methods: In this descriptive study, a number of 260 midwifery students, studying in their 1st to 8th semester at Tehran medical universities participated. The sampling was done through census and the means for collecting data was questionnaire. Its validity was carried by contents validity and its reliability was assigned by means of t-test (r=0.9). The information achieved were analyses by SPSS program using Spirman correlation coefficient and statistic test of χ2. Results: Findings showed that midwifery students, interests in their career were not favorable (%37.5) and the majority of them had not selected their career with enough interest. The most important factors for interest in the career were the occupation that is usefull in personal life and the exciting experiences in this career. There was positive correlation between selecting career in regard personal trends and current interest in the career. Also, there wasn’t significant relation between interest in the career and parents, qualification, occupation and students, semester. Conclusion: With regard to findings of this study, it can conclude that the midwifery students did not evaluate their career equivalent with their needs and this fact might lead to health system damage. So, it is necessary for all midwifves to be responsible to try to find out the reasons of this problem and try to solve them. Moreover reviewing in accepting higher education students is essential

Italian Journal of Public Health , 2008, DOI: 10.2427/5857
Abstract: Background: Logistic regression is one of the most widely used models to analyze the relation between one or more explanatory variables and a categorical response in the field of epidemiology, health and medicine. When there is strong correlation among explanatory variables, i.e.multicollinearity, the efficiency of model reduces considerably. The objective of this research was to employ latent variables to reduce the effect of multicollinearity in analysis of a case-control study about breast cancer risk factors. Methods: The data belonged to a case-control study in which 300 women with breast cancer were compared to same number of controls. To assess the effect of multicollinearity, five highly correlated quantitative variables were selected. Ordinary logistic regression with collinear data was compared to two models contain latent variables were generated using either factor analysis or principal components analysis. Estimated standard errors of parameters were selected to compare the efficiency of models. We also conducted a simulation study in order to compare the efficiency of models with and without latent factors. All analyses were carried out using S-plus. Results: Logistic regression based on five primary variables showed an unusual odds ratios for age at first pregnancy (OR=67960, 95%CI: 10184-453503) and for total length of breast feeding (OR=0). On the other hand the parameters estimated for logistic regression on latent variables generated by both factor analysis and principal components analysis were statistically significant (P<0.003). Their standard errors were smaller than that of ordinary logistic regression on original variables. The simulation showed that in the case of normal error and 58% reliability the logistic regression based on latent variables is more efficient than that model for collinear variables. Conclusions: This research indicated that logistic regression based on latent variables is more efficient than logistic regression based on original collinear variables.

Abstract: Shabnam Salekzamani, Tirang R Neyestani, Hamid Alavi-Majd, Anahita Houshiarrad, Ali Kalayi, Nastaran Shariatzadeh, A'azam GharaviDepartment of Nutrition Research, National Research Institute and Faculty of Nutrition and Food Technology, Shahid Beheshti University of Medical Sciences, Tehran, IranAbstract: This study was undertaken to assess vitamin D status in nonmenopausal women with metabolic syndrome (MeS) and to evaluate its possible role in inflammation and other components of MeS. A case-control study was conducted during late fall and winter 2009–10. A total of 375 women with waist circumference (WC) ≥88 cm were examined to find 100 who met MeS criteria according to the National Cholesterol Education Program (NCEP)/Adult Treatment Panel (ATP) III criteria (NCEP/ATP III). Of those without MeS, 100 age- and residence area-matched women were selected as a control group. Anthropometric and laboratory evaluations were performed. Waist-to-hip ratio (WHR), body mass index (BMI), homeostatic model of insulin resistance (HOMA-IR) and body fat mass (FM) were also evaluated. Women with MeS had significantly higher BMI, waist circumference (WC) and FM but lower serum osteocalcin than controls. There was no significant difference in serum 25 hydroxyvitamin D (25[OH]D), intact parathyroid hormone (iPTH) or vitamin D status between the two groups. Serum highly sensitive C-reactive protein (hsCRP) concentration was significantly higher in the MeS group, compared to the controls (3.4 ± 3.3 vs 2.0 ± 1.9 mg/L, P < 0.001). The difference remained significant even after controlling for BMI (P = 0.011), WC (P = 0.014) and FM (P = 0.005). When comparison was made only in those subjects with insulin resistance (HOMA-IR > 2.4), hsCRP was still higher in the MeS group (n = 79) than in the control group (n = 61) (P < 0.001). When data were categorized according to vitamin D status, in the MeS group significantly higher plasma glucose concentrations were observed in subjects with vitamin D deficiency compared to those with insufficiency or sufficiency (104.0 ± 11.7, 83.0 ± 11.3 and 83.2 ± 9.9 mg/dL, respectively, P < 0.001). Interestingly, their WC or WHR did not show any significant difference. In stepwise regression analysis, 25(OH)D was the main predictor of both hsCRP and plasma glucose. Vitamin D status may, at least in part, be a determining factor of systemic inflammation and the related metabolic derangements of MeS.Keywords: metabolic syndrome, vitamin D, inflammation

Abstract:

Introduction: The essential problems in providing quality and safety services to patients, rapid changes in health care settings as well as information technology require educational revision. Competency-based curriculum focuses on set of skills that students should achieve. This study reviewed characteristics of competency-based curriculum in psychiatric nursing. Methods: A literature review about a competency-based curriculum in psychiatric mental health nursing was carried out by searching databases including Iran Medex, Iran Doc, and Pub Med with key words such as competency-based education, competency-based curriculum, and competency-based curriculum in psychiatric mental health nursing. No time limitation was considered. Results: Results revealed that over 30 literatures have been done about nursing curriculum, but just several studies were done regarding competency-based curriculum and just a few about competency-based curriculum in psychiatric mental health nursing. Conclusion: Competency-based curriculum development is one of the essential steps to facilitate teaching-learning process. The revision of curriculum may decrease theory-practice gap and pave the way for graduates to have essential competences for their roles.

Open Journal of Nursing (OJN) , 2015, DOI: 10.4236/ojn.2015.59083
Abstract: Background: Despite the advances in prenatal care and improving health indicators, preterm delivery and resultant infant mortality rate are still considerable. Emerged financial, social, mental and emotional damages could result in mental and behavioral disabilities for mothers as well as children. Although spontaneous preterm labor is well known as a multifactorial issue, yet poor nutrition is assumed as a strong related factor. Objective: To identify the role of dietary habits on preterm delivery prevalence in Iran, this study was conducted on pregnant women with preterm and term delivery. Methods: In this retrospective case-control study, 70 women with preterm labor and 70 women with term labor were compared in terms of their dietary habits. Women who met the inclusion criteria and referred to two hospitals in North-East of Iran were selected using purposive convenience sampling method and completed 163-item food frequency and dietary habits questionnaire. Results: This study showed that dietary habits of women with preterm labor are more unfavorable compared to women with term labor (P = 0.023). Generally, dietary habit of more than half of the women with preterm labor, in this study, was assessed unfavorable. In terms of different food groups, daily intake of vegetables was significantly lower in women with preterm labor (P = 0.02). Consumption of dairy products was also lower in women with preterm labor than women with term labor which was significant (P = 0.05). Conclusion: To prevent adverse outcomes of preterm delivery more attention regarding nutritional planning for pregnant women seems to be essential.

Abstract: Introduction: In the present research, the association between C-reactive protein (CRP) and high-densitylipoprotein of cholesterol (HDL-C) is studied among healthy adults in Tehran city.Materials and Methods: It is performed as a cross-sectional study using data of adults with age 18 andmore enrolled in the first phase of the "Evaluation of novel risk factors of NCD" project in the ResearchInstitute for Endocrine Sciences (Tehran,Iran) in 2001. Analyses were done by logistic regression modelsusing crude and adjusted odds ratio (OR) to demonstrate the associations between CRP and HDL-Cregarding their age, gender, body mass index and smoking status as underlying variables. To get finalreduced logistic model we used backward elimination strategy with likelihood ratio test.Results: Based on the findings of analysis on data of 126 men and 208 women, it was reported asignificant association between blood concentration of CRP and HDL-C (P<0.001). Logistic regressionanalysis revealed that increasing the concentration of CRP to 0.2 mg/l and more in serum, increased thelikelihood of decreasing the serum concentration of HDL-C to 40 and 50 mg/dl and less about two folds inmen and women respectively (adjusted OR: 2.25, 95% CI: 1.49-3.41).Conclusion: In apparently healthy adults from Tehran city, independent of age, sex, body mass index,blood pressure, fasting blood sugar, and smoking, serum concentrations of CRP and HDL-C are reverselyassociated while both of them are considered as independent factors related with cardiovascular disordersand complications.

Koomesh , 2012,
Abstract: Introduction: Family base association test (FBAT) is widely used in study of genetic association ofallele of genetic markers and different phenotype for locating genes locus. The present study attempted toinvestigate the genetic association of some candidate microsatellites with HDL-C, triglyceride, and waist inorder to find chromosomal area locus of effective genes in metabolic syndromes in Persian and Azaripeople of Iran.Materials and Methods: in this study 107 families were selected from participants in Tehran Lipid andGlucose Study. Each family had at least one member with metabolic syndrome (according to ATP III) andat least two members with reduced HDL-C level. The genetic association of HDL-C, triglyceride, and waistwith some candidate microsatellites in chromosome 8, 11, 12, and 16 was studied using FBAT.Results: the data covered 107 families consisting of 483 individuals. For Persian individuals, study ofChromosome 8 revealed significant association between D8S514 and HDL-C and between D8S1743 andtriglyceride (P<0.05). For Azari individuals, association of D8S1132 and D8S1743 in Chromosome 8 toHDL-C was significant (P<0.05).Discussion: FBAT is robust against confounders such as misspecification of genetic models andpopulation stratification. By finding microsatellites affecting HDL-C, triglyceride, and waist, the resultsfound in this study may be helpful in determining predisposing genes in metabolic syndrome.

Abstract: Introduction: Because of producing large amount of proteomics data and requiring new proceduresfor analyzing them, collective analysis of proteins can help us in identifying new annotation patterns indataset. Furthermore, this type of analysis is a time- consuming process too. Cluster analysis, as a suitablestatistic procedure, can be used for analyzing these datasets. This paper's objective was evaluating theefficiency of fuzzy clustering method in recognizing new patterns within proteins which are related togastric cancers.Materials and Methods: Fuzzy clustering procedure has been used to analyze the identified includedproteins in esophagus, stomach and colon cancers. Proteins were clustered based on three aspects of GeneOntology (GO) and results were compared.Results: Fuzzy clustering was implemented and non-fuzziness indexes based on biological process,cellular component and molecular function were obtained equal to 0.41, 0.55 and 0.35, respectively.Obtained index based on molecular function showed the efficiency of fuzzy clustering method. Despite ofnon-substantial silhouette widths for the entire dataset, most of the proteins in each cluster hadremarkable biological communions. Using Term Enrichment software to determine statistically enrichedGO terms in the entire dataset and clusters, it was cleared that the fuzzy clustering has revealed novelannotation patterns within dataset that would not have been identified otherwise.Conclusion: Considering fuzzy clustering outputs, the efficiency of this method for better and flexibleproteins analysis was cleared. As fuzzy clustering method has placed proteins, that have more similarities,with high probabilities together. Therefore, it can be used for the situations that some of proteins haveunknown characteristics. Furthermore it seems that the proteins clustered via their cellular componentsimilarities, have also biological and functional similarities which this requires more investigations.
