Happiness and Willingness to Communicate in Three Attachment Styles: A Study on College Students

AbstractThe aim of this study was to investigate happiness and willingness to communicate in three attachment styles on college students. using cluster sampling method, 400 students were selected as sample. Hazan and Shaver‘s Adult attachment styles scale, Memorial University of Newfoundland Scale of Happiness (MUNSCH) and willingness to communicate scale were used for collecting of data. Data analysis using one-way analysis of variance (ANOVA) and post hoc multiple comparison were performed. the results showed that there are significant difference among attachment styles on happiness. Students with secure attachment style than non-secure have a higher happiness and student with avoidant attachment style compared with ambivalent attachment have a higher happiness. Another result showed that there are significant differences among attachment styles on willingness to communicate. Students with secure attachment style than non-secure students have a higher willingness to communicate and also students with ambivalent attachment style compared with avoidant students have a higher willingness to communicate. these results suggest that secure attachment style is a main factor in happiness and willingness to communicate of individuals

Estimation of CO2 solubility in aqueous solutions of commonly used blended amines: Application to optimised greenhouse gas capture

One of the key concerns in the 21st century, alongside the growing population, is the increase in energy consumption and the resulting global warming. The impact of CO2, a prominent greenhouse gas, has garnered significant attention in the realm of CO2 capture and gas purification. CO2 absorption can be enhanced by introducing some additives into the aqueous solution. In this study, the accuracies of some of the most up-to-date computational approaches are investigated. The employed machine learning methods are hybrid-adaptive neuro-fuzzy inference system (Hybrid-ANFIS), particle swarm optimization-adaptive neuro-fuzzy inference system (PSO-ANFIS), least-squares support vector machines (LSSVM) and genetic algorithm-radial basis function (GA-RBF). The developed models were used in estimating the solubility of CO2 in binary and ternary amines aqueous solutions. i.e. blends of monoethanolamine (MEA), triethanolamine (TEA), aminomethyl propanol (AMP), and methyldiethanolamine (MDEA). This modeling study was undertaken over relatively significant ranges of CO2 loading (mole of CO2/mole of solution) as a function of input parameters, which are 0.4–2908 kPa for pressure, 303–393.15 K for temperature, 36.22–68.89 g/mol for apparent molecular weight, and 30–55 wt % for total concentration. In this work, the validity of approaches based on different statistical graphs was investigated, and it was observed that the developed methods, especially the GA-RBF model, are highly accurate in estimating the data of interest. The obtained AARD% values for the developed models are 18.63, 8.25, 12.22, and 7.54 for Hybrid-ANFIS, PSO-ANFIS, LSSVM, and GA-RBF, respectively

Study of Metabolic Syndrome Based on the NCEP/ATP III Criteria in People at Risk for Diabetes

Background and Objectives: Metabolic syndrome (MS) is a group of metabolic disorders, which its prevalence is growing worldwide and increases the risk of diabetes and cardiovascular diseases. In the present study, the metabolic syndrome status was investigated based on the NCEP/ATP III criteria in individuals at risk for diabetes. Methods: In this descriptive cross-sectional study, 514 individuals at risk of diabetes (20 to 60 years old), who referred to Amir-Al-Momenin Hospital of Ahvaz, entered the study based on inclusion and exclusion and using convenience sampling method. Data collection tools were demographic characteristics questionnaire, and anthropometric data entry checklist, systolic and diastolic blood pressure, and blood biomarkers (blood sugar, fasting blood sugar, triglyceride, etc.). In this study, MS was evaluated based on NCEP /ATP III criteria, which the presence of three or more than five criteria was indicative of the existence of this syndrome. Data analysis was performed using independent t-, Chi-square, and Pearson correlation tests at a significance level of 95%. Results: In this study, the most common ATP III criterion was abdominal obesity in patients at risk for diabetes. In general, 1.75% of statistical population had MS. Also, the prevalence of MS in women at risk for diabetes and non-employees was significantly higher. Also, there was a significant correlations between waist circumference and all the parameters, except FBS. Conclusion: The results of this study showed that the prevalence of MS in people at risk for diabetes is very high in the city of Ahvaz. Therefore, the risk of type II diabetes and cardiovascular diseases is very high in these individuals and requires serious corrective measures and special attention of health policy makers to this group. &nbsp

Effects of Slow-stroke Back Massage on Chemotherapy-induced Nausea and Vomiting in the Pediatrics with Acute Leukemia: a Challenge of Controlling Symptoms

Introduction Nausea and vomiting are the most common side effects of chemotherapy in the pediatrics with cancer which affect their quality of life. Use of some methods of complementary medicine in leukemia patients is problematic. Because, leukemia patients are at risk of infection and bleeding, therefore the use of acupressure, acupuncture, and deep massage can be risky in these patients. Slow- stroke back massage is applied on the surface of body, so does not have complications. No study has addressed the effect of massage therapy on chemotherapy-induced nausea and vomiting in pediatrics with acute leukemia in the world.  Material and methods This study was a two-group randomized controlled trial (RCT), double blind and repeated measures design. In this RCT, 45 school age children with acute leukemia were placed in the massage and control groups. Before start of the study, at the day of chemotherapy administration (day 1th), only nausea and vomiting were measured. Then during 6 days next (day 2 through 7), the intervention group received 5-minutes Super Smash Bros. Melee (SSBM), immediately before start of each session of chemotherapy. Nausea was measured during chemotherapy, 0.5 h and 3 h after each session of chemotherapy in the two groups. Also vomiting was recorded during 24 h after each session of chemotherapy. Repeated measures ANOVA, Chi-square, and t-test were used for analysis. Results Most of pediatrics were male (58.13%), and suffered from Acute myeloid leukemia (AML) (81.7%). The repeated measure analysis showed that in the intervention group, the SSBM reduced progressive mean of nausea severity and frequency of vomit over time. While, this side effects have slightly increased over time in the control group. Conclusion The results of this study are suggesting that SSBM, as a non-pharmacologic, easy and safe method, is effective in controlling Chemotherapy-induced nausea and vomiting (CINV) in the pediatrics with acute leukemia

The challenge of deciding between home-discharge versus hospitalization in COVID-19 patients: The role of initial imaging and clinicolaboratory data

Background/Objective: It is important to predict the COVID-19 patient's prognosis, particularly in countries with lack or deficiency of medical resource for patient's triage management. Currently, WHO guideline suggests using chest imaging in addition to clinicolaboratory evaluation to decide on triage between home-discharge versus hospitalization. We designed our study to validate this recommendation to guide clinicians. This study providing some suggestions to guide clinicians for better decision making in 2020. Methods: In this retrospective study, patients with RT-PCR confirmed COVID-19 (N = 213) were divided in different clinical and management scenarios: home-discharge, ward hospitalization and ICU admission. We reviewed the patient's initial chest CT if available. We evaluated quantitative and qualitative characteristics of CT as well as relevant available clinicolaboratory data. Chi-square, One-Way ANOVA and Paired t-test were used for analysis. Results: The finding showed that most patients with mixed patterns, pleural effusion, 5 lobes involved, total score ≥10, SpO2% ≤ 90, ESR (mm/h) ≥ 60 and WBC (103/μL) ≥ 8000 were hospitalized. Most patients with Ground-glass opacities only, ≤3 lobes involvement, peripheral distribution, SpO2% ≥ 95, ESR (mm/h) < 30 and WBC(103/μL) < 6000 were home-discharged. Conclusions: This study suggests the use of initial chest CT (qualitative and quantitative evaluation) in addition to initial clinicolaboratory data could be a useful supplementary method for clinical management and it is an excellent decision making tool (home-discharge versus ICU/Ward admission) for clinicians

Prevalence and the Relationship between Characteristics and Parental Conditions with Risk Factors for Sudden Infant Death Syndrome (SIDS)

Introduction  Sudden Infant Death Syndrome (SIDS) is a disease which causes unexpected death of infants aged less than 1 year. Given the undeniable role of parents in the presence or absence of SIDS risk factors, the present study aimed to studythe prevalence and the relationship between characteristics and conditions of parent’s infants with SIDS risk factors. Materials and Methods  In this cross-sectional descriptive-analytic study, 1,021 infants aged 1 to 12 months in the health centers in Qom-Iran in 2014 were selected as the sample by stratified random sampling method. The required data were collected using an author-made questionnaire on SIDS risk factors. The obtained data were analyzed by descriptive and inferential statistics in SPSS 18 at a significance level of 95%. Results 4.5% of mothers were younger than 20 years, 92.3% infants had a co-sleeping with their parents, and 35.7% of infants had a bed-sharing with their parents. 19% of infants used Soft pillow. Study findings showed that there is no significant relationship between the age of mothers and using a shared bedroom (P>0.05), while such a relationship exists between education backgrounds of parents and sharing a bedroom (

Pediatric Nurses’ Medication Error: the Self-reporting of Frequency, Types and Causes

Background Medication errors (MEs) are the most common types of medical errors which effecting on pediatric safety. For decrease MEs, we should to have information about difference aspects of MEs. We have no study which assessed the frequency, types and causes of MEs made by pediatric nurses, in Iran. Material and Methods This was a cross-sectional study, which performed on 53 Pediatric Nurses. Data were collected by a self-structured questionnaire for assessment of MEs contained 3 parts: 1- one question about the fact that, do you had MEs in past 3 months; 2- types of MEs occurred (12 items); 3- causes of MEs from nurses’ perspective (20 items). The MEs in past 3 months gathered through pediatric nurses’ self-report. Descriptive statistics and Chi-square test were used for analysis. Data were analyzed using the SPSS. Results The majority of participants were female (77.3%), and initial (novice) nurses (33.9%). The results showed that, 31 (58.4%) of nurses were reported at least one MEs history and totally, 131 MEs were occurred in past 3 months. Most prevalent of MEs types were reported: wrong dose (36.6%) and wrong drug preparation (14.5%). Also, most prevalent of MEs causes from Nurses’ perspective were reported: poor medication knowledge (96.2%) and poor calculation skills (73.5%). Conclusion With using of this study results, we can program for prevention/decrease MEs and enhancing pediatric safety. On the basis of this study, actually we should enhancing level of nurses knowledge by education and to carry out special courses for pediatric nurses

Evaluation and comparison of statistical models of hemodialysis adequacy in hemodialysis patients in two groups (fistula and permanent catheter) in Arak dialysis center

Background: Adequacy of dialysis is a very important issue in dialysis patients, so comparing the adequacy of dialysis in different dialysis methods is very important. Therefore, due to the fact that the number of people undergoing dialysis  through fistulas and catheters varies in different centers, and depending on different centers, there is a possibility of decreasing or increasing the adequacy of dialysis, so we decided to do this comparison in Arak support center. Methods: In this analytical-cross-sectional study, the dialysis patients of Hami Arak Center from April 2019 to September 2019 were divided into two groups (the first group with permanent catheter, the second group with arteriovenous fistula) based on vascular access. The both groups were matched in terms of age, sex, weight, pump speed, filter size and also the duration of dialysis. All patients were dialyzed with the same type of dialysis machine, and the duration of hemodialysis for all samples was 4 hours in each session. To confirm the reliability of the device, it was calibrated before each use and the same setting was used for all samples. The blood samples were taken from the arterial route before dialysis and starting the dilution with heparin or normal saline. Statistical models of dialysis adequacy of patients in two groups were measured using the Kt/V criterion, SPSS and AMOS data analysis was performed. Results: In the analysis of covariance of BUN before dialysis, there is a statistically significant difference in the studied groups (P<0.05), also in the UF and URR variables, dialysis time and the number of times of dialysis in three consecutive repetitions, there is a statistically significant difference in the studied groups. (dime fistula and catheter) are not present (P<0.05). Conclusion: In this study, during repeated repetitions, 22% of the dialysis adequacy in the two groups did not have good adequacy, and 78% of the patients in the two groups had appropriate dialysis adequacy

cAMP-Epac Pathway Stimulation Modulate Connexin-43 and MicroRNA-21 Expression in Glioma Cells

Introduction: Malignant astrocytic gliomas are the most common and lethal brain malignancies due to their refractory to the current therapies. Nowadays, molecular targeted therapy has attracted great attention in treatment of glioma. Connexin 43 (Cx43) and micro ribonucleic acid- 21(miR-21) are among molecules that are involved in glioma development and progression. These molecules showed potential to be as target molecules with regard to glioma. Some studies have reported that cyclic adenosine monophosphate (cAMP) signaling could be effective on Cx43 and miR-21 in tissues other than in brain. We investigate possible relationship between β-adrenergic receptor and its newly described downstream, exchange protein directly activated by cAMP (Epac) signaling pathway and expression of Cx43 and miR-21 in low (1321N1) and high grade (U87MG) glioma cell lines. Methods: We treated cells with β-adrenergic agonist and Epac activator with and without adenyl cyclase inhibitor. Cx43 and miR-21 expression were measured with real-time PCR. Results: Our data showed that in 1321N1 cells, β-adrenergic-Epac pathway stimulation up and down-regulated Cx43 and miR-21 expression respectively. Whereas, in U87MG cells these interventions had no effect on Cx43 and miR-21 expression. Discussion: These findings demonstrate that low grade astrocytoma cells have better response to our pharmacological interventions
