Background: Recurrent pregnancy loss (RPL) refers to the incidence of two or more abortions before the first half of pregnancy. Oxidative stress has been hypothesized to play a central role in RPL. Objective: To investigate the relationship between Q192R and L55M polymorphisms of PON1 as antioxidant enzyme and the risk of RPL. Materials and Methods: In this case–control study, 110 women with RPL (case) and 110 healthy fertile women (control) referred to the Research and Clinical Center for Infertility, Shiraz, Iran were enrolled. Genomic DNA was extracted from the peripheral blood in all participants. Polymorphisms were genotyped by polymerase chain reaction-restriction fragment length polymorphism method. Results: Statistical analysis of Q192R polymorphism showed a significant difference for the RR genotype between the case and control group (OR = 11, CI = 1.39–86.87, p = 0.005) but none for the QR and QQ genotypes. No significant association was observed between the R and Q allelic frequency in the RPL participants compared to the control group (p = 0.53). Also, statistical analysis of the L55M polymorphism for MM genotype in the case group compared with the control group showed a significant difference (OR = 3.59, CI = 0.97–13.30, p = 0.042), but none for the LM and LL genotypes. Conclusion: The findings showed a significant correlation between the Q192R polymorphisms and the L55M PON1 enzyme and RPL in this study population. Key words: Pregnancy, Abortion, PON1, Polymorphism, Recurrent pregnancy loss.

Background: Genetic factors could account for recurrent pregnancy loss (RPL). The RAN gene is a member of the ”large RAS family” and a small GTPase that is essential for the translocation of Ribonucleic acid (RNA) and proteins through the nuclear pore. Mutation in the RAN constitutive gene could stop DNA synthesis and alter the expression of genes in the uterus, likely playing a role in recurrent miscarriage. Objective: The aim was to investigate the frequency of RAN (rs 14035) polymorphism in women with RPL compared with women without abortion history. Materials and Methods: In this case-control study, 100 women with at least two consecutive miscarriages before the 20th wk of gestation and having spouses with karyotype and normal sperm parameters as the case group and 100 women with no history of abortion and having at least one successful pregnancy and normal delivery as the control group. The groups were age matched (20-40 yr). The rs 14035 polymorphism of RAN gene was investigated by Polymerase Chain Reaction- Restriction Fragment Length poly morphism technique and the frequency of which was compared between the two groups. Results: The frequency of TT, TC, and CC genotypes of RAN gene polymorphism in the case group were 9%, 40%, and 51%, respectively, and in the control group were 11%, 38%, and 51%, respectively. There was no significant difference in the genotypes between two groups (p = 0.882). Conclusion: According to our results, it seems that RAN polymorphism (rs 14035) is not associated with the risk of RPL in this study population. Key words: RAN gene, Repeated abortion, Polymorphism, PCR-RFLP.

Objective. Patients with more than two spontaneous pregnancy losses are diagnosed with recurrent pregnancy loss. The aim of this study was to evaluate the IR (insulin resistance) in patients with idiopathic recurrent pregnancy loss.Material and Method. A single center, case control study was performed on one hundred eighteen women divided into case group (with at least two pregnancy losses, earlier than 20 weeks of gestation, and negative for the recurrent pregnancy loss testing) and control group (with at least one live birth, no pregnancy loss). FG (fasting glucose) and FI (fasting insulin) were determined for all patients. IR was evaluated by HOMA-IR index.Results. There were not significant differences between the mean age and BMI in cases and controls (P>0.05). Fasting glucose was significantly higher in the control group (85.6 versus 79.8P<0.01), but fasting insulin (15.24 versus 12.83,P<0.001) and HOMA-IR (2.98 versus 2.69,P<0.05) were significantly higher in the case group.Conclusion. In women with idiopathic recurrent pregnancy loss FI and IR are higher than those in women without spontaneous abortion.

AbstractBackgroundRecurrent pregnancy loss (RPL) referred to two or more consecutive abortions before 20th week of pregnancy. The imbalance of inflammatory factors such as interleukins (IL) can be a significant factor in the RPL. The aim of this study was to investigate association of interleukin-33 (IL-33) gene rs16924159 polymorphism and RPL in Iranian Azeri women.Materials and methodsThis case-control study consisted of 100 women with RPL as case group and 100 healthy controls with successful delivery. Genomic DNA was extracted from whole blood samples using salting out method. The fragments of the rs16924159 polymorphism were amplified by PCR and the genotyping was performed using DNA sequencing.ResultsThe obtained results showed that frequency of GA genotype and G allele of rs16924159 polymorphism in the case group was significantly more than healthy controls (p = 0.033).ConclusionsGenerally, we showed that the IL-33 gene rs16924159 polymorphism may play an important role in risk of RPL in the Iranian Azeri women. However, further studies on different races and geographic areas can be useful in identification of effects of rs16924159 polymorphism on RPL.

<b><i>Aim:</i></b> The aim of this study is to examine possible associations between the transfusion of RBC or platelets (PLTs) and the development of retinopathy of prematurity (ROP) in infants. <b><i>Methods:</i></b> This retrospective, national, case-control study included all live births in Switzerland between 2013 and 2018. We investigated preterm infants at a gestational age of &#x3c;28 weeks, who developed higher stage ROP (≥stage 2, <i>n</i> = 178). Each case infant was matched to another of the same sex who did not develop ROP (<i>n</i> = 178, control group). <b><i>Results:</i></b> When compared with the control group, we observed higher numbers of RBC transfusions per infant and higher percentages of infants receiving PLT transfusions in the case group. An adjusted logistic regression analysis revealed that both RBC (odds ratio [OR] 1.081, 95% confidence interval [CI] 1.020–1.146) and PLT transfusions (OR = 2.502, 95% CI 1.566–3.998) numbers were associated with ROP development. <b><i>Conclusions:</i></b> Multiple RBC and PLT transfusions are associated with higher stage ROP development. Prospective studies are required to determine their potential as risk factors.

Abstract Background In March 2020, the US Food and Drug Administration decided that the dangers related to neuropsychiatric events (NPEs) of montelukast, one of the leukotriene modifying agents (LTMAs), should be communicated through ‘boxed warning’. In case of NPEs, the prevalence has been the highest in elderly people. Because the characteristics of the elderly such as old age itself can act as risk factors. Therefore, an investigation on safety of LTMAs related to NPEs in elderly using LTMAs is needed. Method A nested case-control study using an elderly sample cohort from the Korean National Health Insurance Service database was used. The asthma cohort included asthma patients newly diagnosed between 2003 and 2013. Within the asthma cohort, the case group was defined as patients who were diagnosed with NPEs. Among patients who had never been diagnosed with NPEs, the control group was selected by matching 1:1 by propensity score. Patients who were prescribed LTMAs for 1 year prior to index date were defined as the exposure group. The logistic regression model was used to measure the effect of LTMAs on NPEs. Results We identified 141,165 patients with newly diagnosed asthma, and selected 31,992 patients per each case and control group. Exposure to LTMAs significantly increased the risk of overall NPEs about in comparison with the absence of exposure (crude odds ratio [OR] 1.58, 95% CI 1.50–1.68). After adjusting for confounding factors, the overall NPEs risk increased (adjusted OR, 1.67, 95% CI 1.58–1.78). Conclusion This study suggests that elderly asthma patients prescribed LTMAs had a higher risk of NPEs than patients who were not treated with LTMAs. Therefore, clinicians should be aware of the potential risks of LTMAs.

Abstract Background Coronary hearth diseases are among the main causes of death in adults. Increase of oxidative stress and defects in antioxidant defense play a major role in endothelium performance and are an effective factor in progress of atherosclerosis. Some studies have also reported different malondialdehyde and total antioxidant capacity among the atherosclerosis patients.Methods In this case-control study, 44 atherosclerosis patients referring to Shahid Madani treatment-education center were considered as the case group; while 44 healthy peoples were placed in the control group. Demographic data and anthropometric indices were measured. Food frequency questionnaire and international physical activity questionnaires were also completed. After 12 hours of fasting, 10 ml blood was sampled from the participants. Uric acid, vitamin C, TAC and MDA were also measured. The data were finally analyzed by SPSS Ver 22 software.Results A significant difference was observed between the two groups in terms of uric acid (P<0.001) and vitamin C (P<0.03). However, mean MDA and TAC showed no significant difference between the two groups. The two groups’ difference in terms of vitamin A, E and beta carotene, zinc and selenium intake was not significant. A significant difference was however detected between the two groups in terms of vitamin C (P<0.047). A significant relationship was also observed between the systolic pressure and CHD (P<0.028).Conclusion Results of this study indicated that the uric acid and vitamin C levels of atherosclerosis patients had significant increase and decrease in comparison with the healthy subjects, respectively. Mean TAC and antioxidant levels of their diets (except for vitamin C) showed no significant difference. Systolic blood pressure of the patients was significantly higher than the controls.

Background: Polycystic Ovarian Syndrome (PCOS) is one of the most common causes of infertility in women. Objective: The current study investigated mental and personality disorders in infertile women with and without PCOS. Methods: This case-control study evaluated 400 infertile women who referred to the Infertility Center in Babol city (North of Iran). Participants were categorized into the case group (201 PCOS) and the control group (199 without PCOS). All of the participants completed the Millon Clinical Multi-axial Inventory-III (MCMI-III). Results: The mean scores for clinical personality patterns were significantly higher for six personality disorders (schiz- oid, avoidant, antisocial, depressive, sadistic, and negativistic) and for three classes of severe personality disorder patterns (schizotypal, borderline, and paranoid) in infertile women with PCOS than in women without PCOS. The mean scores for eight clinical disorders (somatoform, manic disorder, dysthymia, alcohol-dependence, drug-dependence, post-trauma stress disorder, major depression, and delusion disorder) were also higher in infertile women with PCOS than in women without PCOS. Conclusion: The scores of many mental and personality disorders are higher in infertile women with PCOS than in women without PCOS. Thus, clinicians should prioritize recognizing and treating psychological problems of infertile women with PCOS. Keywords: Polycystic ovarian syndrome; infertility; personality disorders.
