The Role of Voluntary Function in Predicting Addiction Potential: A Survey on Iranian Red Crescent Societies

Background and Aim:Considering Voluntary Function, the purpose of the present study was to predictthe addiction potential among some members of the Iranian Red Crescent Society (IRCS).Materials and Methods:The research method was descriptive-correlational. The statistical population of the present study was all members of the Iranian Red Crescent Society (IRCS). The sampling method was multi-stage cluster sampling, in which 620 active volunteers of the IRCS from 31 province and 175 cities of Iran (48.7% female and 50.1 Male mean age 23.27±3.32, range 14–31 years)were selected for this research.The research data was collected using theIranian Addiction Potential Scale (IAPS) and Voluntary Function Inventory (VFI). Results:Findings proved that there was a negative significant correlation between the AP and all measurements of VF such as protective enhancement, understanding, career, values, and motives; meaning that the more time youth spent on participating in voluntary activities, the less likely they sought to resort to misusing AP. Findings of the multiple regression has proved that volunteerism could predict 15% of changes in the AP as a criterion variable.Conclusion:Voluntary function can increase happiness, mental health, expand interpersonal relationships and social networking, self-esteem and social skills in individuals. These skills can reduce the high-risk behaviors, including addiction. Therefore, it is necessary to pay attention to this valuable factors in preventive programs

High-Performance and Biobased Polyamide/Functionalized Graphene Oxide Nanocomposites through In Situ Polymerization for Engineering Applications

In this study, biobased polyamide/functionalized graphene oxide (PA-FGO) nanocomposite is developed using sustainable resources. Renewable PA is synthesized via polycondensation of hexamethylenediamine (HMDA) and biobased tetradecanedioic acid. Furthermore, GO is functionalized with HMDA to improve its compatibility with biobased PA and in situ polymerization is employed to obtain homogeneous PA-FGO nanocomposites. Compatibility improvement provides simultaneous increases in the tensile strength, storage modulus, and conductivity of PA by adding only 2 wt% FGO (PA-FGO2). The tensile strength and storage modulus of PA-FGO2 nanocomposite are enhanced dramatically by ≈50% and 30%, respectively, and the electrical conductivity reached 3.80 × 10–3 S m−1. In addition, rheology testing confirms a shear-thinning trend for all samples as well as a significant enhancement in the storage modulus upon increasing the FGO content due to a rigid network formation and strong polymer-filler interactions. All these improvements strongly support the excellent compatibility and enhanced interfacial interactions between organic–inorganic phases resulting from GO surface functionalization. It is expected that the biobased PA-FGO nanocomposites with remarkable thermomechanical properties developed here can be used to design high-performance structures for demanded engineering applications.Peer reviewe

Investigating the Effect of Optimism Training during Pregnancy on Attitude and Mode of Delivery in Nulliparous Women Referred to Health Centers of Mashhad, 2014

Abstract Background: Childbirth is a stressful event that requires a mental adjustment. Optimism is one of the important determinants of psychological adjustment which is a combination of interest and positive attitude. The purpose of this study was to determine the effect of optimism training during pregnancy on attitude and intentions to choose the mode of delivery in nulliparous women. Materials and Methods: In this clinical trial , 64 primipar pregnant women with normal pregnancies, 34-30 weeks, without indication for cesarean section referring to the health centers in Mashhad in 2014 were selected and were randomly divided into two groups , A (trained) and B (no training). Optimism training during 5 session of the 60-minute, with the group participation of participants and active exercises was conducted. Data were analyzed with using the software SPSS and statistical tests including variance analysis, Fischer exact test, willcoxon, Square-Chi and paired t-test. Results: Average attitude score towards c/s delivery in the study group, before and after training has a significant difference (p<0.001). Average attitude score towards natural childbirth was significantly higher in intervention group compared to the control group (p<0.002). Frequency of intentions to choose the mode of delivery in the study group, before and after training has a significant difference (p<0.033). Conclusion: Reults showed that optimism training in creating a positive attitude towards natural childbirth and thus reducing the rate of elective c/s delivery is effective

Association between Thrombophilic Gene Polymor-phisms and Recurrent Pregnancy Loss in Iranian Women

Background: Recurrent pregnancy loss (RPL) is a common problem among couples, and acquired thrombophilia is the well-known etiology of RPL. The aim of this study was to establish the association between inherited thrombophilic gene polymorphisms and RPL. Methods: This case-control study was conducted on 50 women with unexplained RPL and 50 parous women with no history of miscarriage (age range: 17–48 years). The data were collected during 2013–2015 in Sarem Hospital, Tehran, Iran. Genotyping was performed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for glycoprotein IIIa (PLA1/PLA2), KDR (Q472H), and β-fibrinogen (-455G/A); tetra-primer amplification refractory mutation system (ARMS)-PCR for glycoprotein Ia (807c/t) and vascular endothelial growth factor (VEGF) (2578c/a), and ins/del PCR for angiotensin I-converting enzyme (ACE) (intron 16 I/D). The association between the frequency of the genotypes and RPL was determined by Chi-square and Fisher’s exact tests. Results: The results of the present study revealed a significant relationship between glycoprotein Ia (807C/T), VEGF (2578C/A), and ACE (intron 16 I/D) polymorphisms and RPL (P=0.00, 0.02, and 0.00, respectively). In contrast, no relationship was observed between β-fibrinogen (-455G/A), KDR (Q472H), and glycoprotein IIIa (PLA1/PLA2) polymorphisms and increased risk of RPL (P>0.05). Conclusion: This study demonstrated that glycoprotein Ia (807C/T), VEGF (2578C/A), and ACE (intron 16 I/D) polymorphisms may be a risk factor for the women with a history of RPL

Cord blood antibodies following BBIBP‐CorV (Sinopharm) vaccination during pregnancy

Abstract Objective This study aimed to evaluate the maternal and umbilical cord blood antibody levels, after COVID vaccination during pregnancy. Method The women who received the COVID‐19 vaccine (Sinopharm) during pregnancy were included. Maternal and cord blood samples were tested to detect the severe acute respiratory syndrome coronavirus 2 receptor binding domain (RBD) specific antibodies. In addition, obstetric information and side effects after vaccination were gathered. Result A total of 23 women were included. Eleven pregnant women took two doses and 12 cases received a single dose of the vaccine. No IgM antibody was detected in any maternal blood or cord blood samples. The RBD‐specific Immunoglobulin G (IgG) antibody was positive in mothers receiving 2 doses of the vaccine and their infants. But the antibody titers were under the positive cut‐off threshold for the other 12 women who were vaccinated with a single dose. Women who received both doses of vaccine had significantly higher IgG levels than a single dose of Sinopharm (p = .025). The same result was demonstrated in infants born to these mothers (p = .019). Conclusion There was a significant correlation between maternal and neonatal IgG concentrations. Although, receiving both doses of the BBIBP‐CorV vaccine (not 1 dose) during pregnancy is highly beneficial for increasing humoral immunity for the mother and fetus
