Comparing the immunogenicity of COVID-19 infection and vaccination in pregnant women as measured by anti-S IgG.

BACKGROUND: Pregnancy is a critical time for women, making them more susceptible to infectious diseases like COVID-19. This study aims to determine the immunogenicity of COVID-19 in pregnant women who have been infected compared to those who have received the inactive COVID-19 vaccine. MATERIALS AND METHODS: In this retrospective cohort study, pregnant women who received the inactivated COVID-19 vaccine (Sinopharm) and those with a history of COVID-19 infection during pregnancy were studied. Participants who had experienced stillbirth, received different COVID-19 vaccines, or had intrauterine fetal death were excluded from the study. Overall, the study included 140 participants. The participants were divided into two groups of 70 participants - pregnant women who received the Sinopharm vaccine and pregnant women who had COVID-19 infection during pregnancy. Before delivery, blood samples were collected from all mothers to evaluate the maternal immunoglobulin G (IgG) level. Blood samples were also taken from the baby's umbilical cord during delivery to measure the newborn's IgG level. Additionally, blood samples were collected from babies whose mothers showed signs of acute infection to measure their IgM levels and evaluate vertical transmission. FINDINGS: The study found a significant relationship between the mean level of maternal IgG and umbilical cord IgG within the groups (P < 0.001). The highest levels of maternal IgG (2.50 ± 2.17) and umbilical cord IgG (2.43 ± 2.09) were observed in pregnant women with a previous COVID-19 infection and no history of vaccination (P < 0.001). Only one baby was born with a positive IgM, and this baby was born to a mother who showed signs of COVID-19 infection in the last five days of pregnancy. The mother was 28 years old, with a BMI of 33; it was her first pregnancy, and she gave birth to a male newborn at term. CONCLUSION: Administering an inactivated vaccine during pregnancy can generate immunity in both the mother and the child. However, the vaccine's immunity level may not be as potent as that conferred by COVID-19 infection during pregnancy. Nonetheless, the risk of vertical transmission of COVID-19 is considered minimal and can be classified as negligible.

The structure of pathological personality traits and temperament in a Persian community sample.

The present study examined the extent to which the currently established factor structure of the Personality Inventory for DSM-5 (PID-5; Krueger et al., 2013) generalizes to a large Persian community sample, as well as relations between the resulting PID-5 factors and two temperament measures. Cross-sectional data came from 946 adults (65% female) from western Iran. With the use of exploratory structural equation modeling (ESEM) with target rotation, we found factor loadings that showed fairly similar patterns to those found in two previous meta-analytic PID-5 studies with predominantly North American and European samples (Watters & Bagby, 2018; Somma et al., 2019). Despite slight differences in each of the target rotations, there were moderate congruence coefficients (~0.85) between loadings for the five PID-5 domains, with the weakest evidence supporting the Disinhibition factor. The resulting PID-5 factors showed meaningful associations with temperament domains assessed via the Temperament and Character Inventory (TCI; Cloninger, 1994) and Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Autoquestionnaire (TEMPS-A; Akiskal et al., 2005). Overall, our findings suggest that the documented structure of personality pathology assessed by the PID-5 generalizes somewhat to this sample of Persian participants, and pathological personality traits show important overlap with temperament, although these constructs are meaningfully distinct.

Opium use and gastrointestinal cancers: a systematic review and meta-analysis study.

Aim: The current systematic review and meta-analysis aimed to assess the association between Gastrointestinal (GI) cancers and opium use. Background: GI malignancies are a global public health issue and are associated with many risk factors including genetic and lifestyle factors. Methods: PubMed, Web of Science, Embase and Scopus and the Google Scholar search engine in addition to Persian databases including Magiran and SID were searched using relevant keywords. The associations of opium use, long duration of opium use, high daily amount opium use and high cumulative opium use and GI cancer and various subtypes of GI cancers were estimated and pooled in format of odds ratios (OR) and their corresponding 95% confidence intervals (CI) with a random effects model. Results: 22 articles that were published between 1983 and 2022 entered the analyses. There were significant relationships between opium use based on crude effect sizes (OR: 2.53, 1.95-3.29) and adjusted effect sizes (OR: 2.64, 1.99-3.51), high daily opium use (or: 3.41, 1.92-6.06), long duration of opium use (OR: 3.03, 1.90-4.84) and high cumulative opium use (OR: 3.88, 2.35-6.41), all compared to never opium use, and GI cancer. The results were not sensitive to sensitivity analyses and no influential publication biases were found in these analyses. Conclusion: Our meta-analysis showed that opium use could be associated with increased risk of overall and some particular GI cancers including oropharyngeal, gastric, pancreatic and colorectal cancers. Opium use as a potentially modifiable factor, therefore, should be more emphasized.

Meta-Analytic Review of Temperamental Correlates of the Five-Factor Model and Hierarchical Taxonomy of Psychopathology Domains.

Background: There is little and heterogeneous knowledge on the links between the temperamental predispositions of psychopathology and the contemporary dimensional models of psychopathology, such as the Hierarchical Taxonomy of Psychopathology (HiTOP) classification system, which can be aligned with the five-factor model (FFM) of personality. This meta-analysis seeks to expand the temperamental theoretical basis of the HiTOP model by incorporating associations of temperament traits of two temperamental theories measured, respectively, by the Temperament and Character Inventory (TCI) and the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A) with (a) the FFM's personality domains and (b) HiTOP's five psychopathological spectra. Methods: A systematic search was done on Web of Science, Scopus, PubMed, ProQuest, Cochrane Database, and Google Scholar for all articles published in English from January 1990 to August 2020. Because of heterogeneity in the results of almost 70% of studies, pooled estimates of correlation coefficients were calculated using the random-effects method. Risk of bias (low-quality studies) and publication bias are reported. Results: The pooled correlations obtained from the analysis of 35 studies showed that the temperamental profile associated with each FFM domain and HiTOP spectra is distinct. Specifically, TCI-harm avoidance (HA) and all TEMPS temperaments were more strongly related to neuroticism/internalizing, extraversion/low detachment, and conscientiousness/disinhibition. In contrast, TCI-novelty seeking was more strongly related to both disinhibited/antagonistic externalizing and thought disorder. Conclusions: A large body of research supports maladaptive variants of all FFM domains and some psychopathological spectra of HiTOP related to the abnormal-range temperaments.

Hospital preparedness assessment for road traffic accidents with mass casualties: a cross-sectional study in Kurdistan Province, Iran.

BACKGROUND: Road traffic accidents (RTAs) are predicted to become the world's seventh leading cause of death by 2030. Given the significant impact of RTAs on public health, effective hospital preparedness plays a pivotal role in managing and mitigating associated health and life-threatening issues. This study aims to meticulously evaluate the preparedness of selected hospitals in western Iran to handle road traffic accidents with mass casualties (RTAs-MC). METHODS: The study employed a descriptive-analytical approach, utilizing a reliable and valid questionnaire to measure hospitals' preparedness levels. Descriptive statistics (frequency distribution and mean) were utilized to provide an overview of the data, followed by analytical statistics (Spearman correlation test) to examine the relationship between hospital preparedness and its dimensions with the hospital profile. Data analysis, performed using SPSS software, categorized preparedness levels as weak, moderate, or high. RESULTS: The study found that hospitals in Kurdistan province had a favorable preparedness level (70.30) to respond to RTAs-MC. The cooperation and coordination domain had the highest preparedness level (98.75), while the human resource management (59.44) and training and exercise (54.00) domains had the lowest preparedness levels. The analysis revealed a significant relationship between hospital preparedness and hospital profile, including factors such as hospital specialty, number of beds, ambulances, staff, and specialized personnel, such as emergency medicine specialists. CONCLUSION: Enhancing preparedness for RTAs-MC necessitates developing response plans to improve hospital profile, considering the region's geographic and topographic features, utilizing past experiences and lessons learned, implementing of Hospital Incident Command System (HICS), providing medical infrastructure and equipment, establishing communication channels, promoting cooperation and coordination, and creating training and exercise programs.

Prevalence of HIV, HBV, HCV, HPV and syphilis among female sex workers in Kurdistan, west of Iran.

Background: Female sex workers (FSWs) in most societies run a high risk of health problems, including sexually transmitted infections (STIs) such as viral infections and syphilis. The present study examines the prevalence of viral infections and syphilis among FSWs. Methods: This cross-sectional study recruited 100 female sex workers (April 2019 to April 2020) who visited the Counseling Center for Behavioral Diseases or were selected via purposeful (snowball) sampling. A questionnaire (demographic information and STI risk factors) was completed in a face-to-face interview with the participants. Blood samples were then taken to test the markers for HBV, HCV Ab, HIV Ab, Rapid Plasma Reagin (RPR) for syphilis and a PCR was taken to test for HPV (in vaginal sex workers from the cervix and anal sex workers from the anal region). The data were analyzed in Stata 14. Results: Among 100 FSWs, 6 (6%) were infected with HIV, 1 (1%) with hepatitis B, and 2 (2%) were anti-HCV positive. 1 (1%) participant was suspected of having syphilis. Based on the PCR tests, 16 (16%) participants were infected with HPV. Moreover, 68 (68%) FSWs reported having unprotected sex. Conclusion: Due to the prevalence of viral infections and syphilis and unprotected sex in FSWs, immediate preventive measures are critical for this vulnerable group to control the transmission of these viral infections in society.

Disease aggravation following surgery in a rare patient suspected to Fibrodysplasia (Myositis) ossificans progressiva: a case report.

BACKGROUND: Fibrodysplasia ossificans progressiva (FOP) as a rare and heritable disorder with the infrequent genetic transmission of the condition is a catastrophic disorder of heterotopic ossification (HO) and a cause of extraskeletal bone formation in humans. Given the lack of effective treatment for this disease, the important point is to avoid aggravating factors such as bone biopsy, surgery, and intramuscular injection. CASE PRESENTATION: In this report, we present a 52-year-old female patient, Kurdish ethnic, suspected to FOP who had a surgical intervention on the second toe of the right foot, which subsequently, it caused further deterioration of the disease in the person including necrosis and amputation of the distal phalanx of the second toe. CONCLUSIONS: Although, based on our investigation and the available scientific evidence, surgery may a cause for faster progression and worsening of the FOP disorder, but its proof requires further studies.

A head-to-head comparison of eight unique personality systems in predicting somatization phenomenon.

BACKGROUND: If somatization is an independent personality trait, it is not clear whether it is specific to the temperament or maladaptive spectrum of personality. We aimed at the head-to-head comparison of temperament and maladaptive systems and spectra of personality to predict both somatization and somatic symptom and related disorders (SSRD). METHODS: The samples included 257 cases with SSRD (70.8% female) and 1007 non-SSRD (64.3% female) from Western Iran. The Personality Inventory for DSM-5 (PID-5), Personality Diagnostic Questionnaire-4 (PDQ-4), Temperament and Character Inventory (TCI), Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-Autoquestionnaire (TEMPS-A), Affective and Emotional Composite Temperament Scale (AFECTS), and Positive Affect and Negative Affect Model (PANAS) was used to data collection. A somatization factor plus temperament and maladaptive spectra of personality were extracted using exploratory factor analysis. Several hierarchical linear and logistic regressions were used to test the predictive systems and spectra. RESULTS: All personality systems jointly predict both somatization and SSRD with a slightly higher contribution for temperament systems. When the temperament and maladaptive spectra were compared, both spectra above each other significantly predicted both somatization (R2 = .407 versus .263) and SSRD (R2 = .280 versus .211). The temperament spectrum explained more variance beyond the maladaptive spectrum when predicting both the somatization factor (change in R2 = .156 versus .012) and SSRD (change in R2 = .079 versus .010). CONCLUSION: All temperament and maladaptive frameworks of personality are complementary to predicting both somatization and SSRD. However, the somatization is more related to the temperament than the maladaptive spectrum of personality.

Association between postictal suppression and the therapeutic effects of electroconvulsive therapy: A systematic review.

Electroconvulsive therapy (ECT) is an effective and safe medical treatment for patients with severe mood and neuropsychiatric disorders. Since the advent of ECT, extensive research has been performed to identify the predictive factors for response to ECT. In recent decades, postictal suppression on an electroencephalogram (EEG) has been considered a potential predictor of response to ECT. We aimed to investigate the direct association between postictal suppression and the therapeutic effects of ECT. In this systematic review, all articles in the field of the association between postictal suppression and the therapeutic effects of ECT published between 1990 and 2021 were identified. The full texts of these articles, which include clinical trials and retrospective and cross-sectional studies, are available in scholarly research databases and search engines, including PubMed, Google Scholar, OVID, Web of Science, and Scopus. Of all retrieved articles, eight studies, including four retrospective cohort articles and four clinical trials, met the inclusion criteria for further analyses. The findings of this study showed a significant association between postictal suppression and the therapeutic efficacy of ECT. Factors such as electrode placement, tachycardia, type of anesthetic agent, and EEG amplitude were also directly related to postictal suppression and the efficacy of ECT. Postictal suppression on EEG can be considered a predictor of response to ECT. To increase the effectiveness of treatment with ECT and increase postictal suppression, factors including electrode placement, tachycardia, type of anesthesia, and EEG amplitude should be considered, which highlights the need for further research.

Construct and criterion validity of the HiTOP spectra to predict dimensional and categorical somatization in a large non-western sample.

The Hierarchical Taxonomy of Psychopathology (HiTOP) is a phenotypic data-driven framework for the classification of psychopathology. We tested the construct and criterion validity of the HiTOP spectra measured by the Personality Inventory for DSM-5 (PID-5) using exploratory structural equation modeling (ESEM) and hierarchical regressions both to predict somatic symptom and related disorders (SSRD) and a somatization factor. The case-control study used hierarchical logistic regressions to distinguish 257 cases with SSRD from 1007 healthy controls by both the maladaptive and the temperament factors. The extracted factors were also used in hierarchical linear regressions to predict the dimensional somatization factor. The seven temperament factors explained more variance above and beyond the five maladaptive factors when predicting SSRD (pseudo R2 = 0.169 to 0.266 versus 0.125 to 0.196; change in pseudo R2 = 0.055 to 0.087 versus 0.011 to 0.017). The temperament factors also explained more variance above and beyond the maladaptive factors when predicting the somatization factor (R2 = 0.392 versus 0.269; change in R2 = 0.146 versus 0.023). Although the HiTOP spectra measured by PID-5 are significant structures related to the categorical and dimensional measurements of somatoform, our findings highlight potential problems with both the construct and criterion validity of the HiTOP spectra.

Effectiveness of supervised implementation of an oral health care protocol on ventilator-associated pneumonia patients in intensive care units: a double-blind multicenter randomized controlled trial.

Background: The available scientific evidence suggests a significant association between oral bacteria and the incidence of ventilator-associated pneumonia (VAP). Aims: The aim of this study was to determine the effectiveness of an oral health protocol in the prevention of ventilator-associated pneumonia. Methods: In this multi-center RCT, conducted in the intensive care units of neurological patients in three general teaching hospitals of two provinces located in the west of the Iran, a consecutive sample of 200 intubated patients were initially recruited. Patients were randomly allocated to the intervention (received oral health care based on evidence-based oral health protocol) or control (routine oral health care) groups. Both groups received their prescribed treatment regimen for seven consecutive days. The percentage of VAP diagnoses as main outcome assessed using clinical pulmonary infection score (CPIS). Findings: The rate of VAP in the intervention and control groups was 5% and 64%, respectively. The intervention reduced the risk of VAP by 97% and this difference was statistically significant (P <0.001). The chance of VAP occurrence in patients with lower levels of consciousness in univariate and multivariate analysis was significantly higher (OR: 2.38; 95%CI: 1.11-5.26) P <0.05). Conclusion: The results of our study suggest that the use of a dynamic supervised oral health care guideline is more effective than the routinely used protocols in the intensive care units of hospitals.

Evaluation of ASGE Criteria for Prediction of Choledocholithiasis: Can Early Endoscopic Ultrasound Utilization Make the Prediction More Accurate?

Background: ASGE predictive model for the detection of choledocholithiasis is a reasonable approach for the management of patients with cholelithiasis. Surgeons do not pursue cholecystectomy without evaluation of the biliary system when laboratory tests and diagnostic imaging evidence show biliary duct involvement. Literature revisions reveal that the prediction of choledocholithiasis based on ASGE criteria suffers from poor accuracy which results in unnecessary ERCPs. We decided to estimate the sensitivity and specificity of the ASGE predictive model for the detection of choledocholithiasis with the hope that early EUS would obviate the need for unnecessary ERCPs among highly probable patients for choledocholithiasis based on ASGE criteria. Methods: This is a prospective intervention and control study on the accuracy of ASGE criteria for the prediction of choledocholithiasis. To evaluate the sensitivity and specificity of ASGE criteria, patients were followed in two groups of controls who were treated based on ASGE guidelines and cases who underwent primary EUS. The clinical relevance of the ASGE criteria was estimated by sensitivity and specificity using SPSS Statistics 28 software. Then, absolute risk reduction utilizing primary EUS was also calculated. Results: The sensitivity and specificity of the ASGE predictive guideline for choledocholithiasis were estimated to be 62.31% and 51.85%, respectively. Evaluation of the ASGE guideline also revealed that patients in the intermediate probability group who finally required ERCP based on EUS results (false-negatives) were estimated to be 49.1% and patients who were predicted to require ERCP but finally did not need ERCP (false positives) were estimated to be 37.68%. The comparison of the two groups revealed the need for ERCP in about 55.56% of the primary EUS group and 77.42% in the ASGE group. Utilization of primary EUS reduced the need for ERCP by an absolute risk reduction of 0.299. (Primary Endpoint). Conclusion: ASGE guideline is associated with the overestimation of ERCP in cholelithiasis. The usage of primary EUS will reduce the need for ERCP.

Elevated interleukin (IL)-6 as a predictor of disease severity among Covid-19 patients: a prospective cohort study.

BACKGROUND: accompanied to the spreading of coronavirus disease 2019 (Covid-19) in the world, identifying factors related to the severity of the disease is one of the interests of physician and medical researchers. We hypothesized that interleukin 6 serum level is associated with severe outcome. METHODS: In this longitudinal prospective cohort study we enrolled 208 confirmed COVID-19 patients who were admitted to the Tohid Hospital (Sanandaj, Iran). Patients were classified into two groups based on IL-6 value in the first day of admission, elevated (n = 107) or not elevated/normal (n = 101), and followed until the occurrence of final outcome (death or discharge from the hospital). Data were analyzed using univariate methods, Chi-squared and independent two sample T test. The relationship between the independent variables and our interesting outcomes were investigated by multiple linear and penalized logistic regression modeling. RESULTS: A total of 208 patients, 51% female and mean age 53.6 ± 16.3 years, including 107 elevated and 101 non-elevated IL-6 patients, were followed. No significant difference was observed between the two groups in demographic and clinical characteristics. Although not significant, logistic regression results showed that the chance of death occurrence among patients with elevated IL-6 are 3.91 times higher. According to the multiple linear regression modeling, elevated IL-6 significantly increased the duration of hospital stay (P = 0.02). Frequency of ICU admission (P = 0.04) and mean of ICU stay (P = 0.8) are also higher in elevated IL-6 group. CONCLUSION: This study revealed that elevated IL-6 is significantly related to prolongation of hospital stay in Covid-19 patients. Although not significant, the occurrence of death among patients who had increased IL-6 in the time of admission was higher than patients with normal or lower serum levels of IL-6.

Physical Development at School Entry in Children with Congenital Hypothyroidism Diagnosed by the National Program of Newborn Screening in Iran.

Background: The newborn screening program for diagnosing and treating children with congenital hypothyroidism (CH) in Iran was established in 2004. Objectives: This study aimed to evaluate the national program's success in maintaining the physical development and anthropometric indexes of children with CH. Methods: This historical cohort study was carried out in five provinces located in five different geographical regions of Iran. The anthropometric indexes, including weight, height, and head circumference of 240 children diagnosed with transient congenital hypothyroidism (TCH) (n = 131) and permanent congenital hypothyroidism (PCH) (n = 109) were measured and compared with those of 240 healthy children aged six. Results: Mean ± standard deviation (SD) of weight, height, and head circumference of children with CH aged six were 20304.8 ± 4457.9 g, 115.6 ± 5.9 cm, and 50.8 ± 1.7 cm, respectively. Mean ± SD of height (116.7 ± 6.1 cm) and head circumference (51.1 ± 1.7 cm) in the control (healthy) group were significantly higher than those of the CH children group (P < 0.05). Mean ± SD weight in the control group (20741.2 ± 4337.3 g) was higher than that in the CH group (20304.8 ± 4457.9 g). However, the difference was not statistically significant (P = 0.3). No significant difference was observed between TCH and PCH children in the subgroup analysis (P > 0.05). Conclusions: Although the mean of anthropometric indexes in CH patients was slightly lower than that in healthy children aged six, the difference between the two groups was insignificant. The physical development of children with CH was evaluated as good. Our results suggested that the newborn screening program for identifying and treating children with CH in Iran may have improved the growth outcomes.

Genetic Regulation of Interleukin-6 and Interleukin-10 in COVID-19 Infection.

Background: The role and regulation mechanisms of the interleukin-6 and 10 (IL6 and IL-10) serum levels and the interaction between CD4+ and CD8+ lymphocytes with SARS-COV-2 IgM and IgG in the context of COVID-19 infection are not fully understood. Methods: This study was conducted on 45 COVID-19 patients and 45 healthy individuals. The IL-6 and IL-10 promoter methylation, IL-6 and IL-10 gene expression, SARS-COV-2 IgM, and IgG antibodies and CD4+ and CD8+ lymphocytes were studied by qMSP-PCR, Real-time PCR, ELISA, and flow cytometry techniques, respectively. Results: The male ratio and mean age of critically ill patients' group were significantly higher in compared to controls (P< 0.05). IL-6 gene expression and serum levels were significantly increased in patients compared to controls (P=0.002, 0.001), but IL-6 promoter methylation was not significantly decreased in patients (P=0.835). The IL-10 promoter methylation and expression were not different between cases and controls (0.326, 0.455), but serum IL-10 levels were higher in patients (P< 0.001). The CD4+ and CD8+ lymphocytes decreased (P< 0.001) and mean SARS-COV-2 IgG increased (P=0.002) in the patients compared to controls. Conclusions: The COVID-19 disease result in severe complications in men and elderly. The serum levels of interleukin-6 and 10 increases in COVID-19 infection, and the gene expression of these two interleukins underlying in this increase. The serum levels of IL-6, IL-10 and SARS-COV-2 IgG as well as CD4+ and CD8+ lymphocyte counts should be investigated to monitor patients and predict the course of disease.

Association of Interleukin-10 Genotypes and Anticyclic Citrullinated Peptide Antibodies with Rheumatoid Arthritis.

Background: According to recent evidence, there is an association between some genetic factors and rheumatoid arthritis (RA). The aim of this study was to determine whether genetic variations in the interleukin 10 (IL10) and anti-cyclic citrullinated peptide (Anti-CCP) antibody loci were linked to RA. Methods: In this hospital-based case-control study with 224 cases and 194 healthy individuals, we investigated the association of IL-10 genotypes and anti-CCP antibodies with RA. Independent sample t, chi-square, and Fisher exact tests were used to assess the association between study variables. Results: Frequency of IL-10 -1082 A/G genotype in RA patients is significantly higher than the control group (odds ratio [OR], 1.67 [95% CI, 1.11-2.51]) (p=0.009), while the frequency of IL-10-1082 A/A and G/G polymorphisms in RA patients was lower than controls and this finding for G/G polymorphism was statistically significant (p=0.01). No significant difference was observed between the 2 studied groups regarding IL-10-592 C/C, C/A, and A/A polymorphisms (p>0.05). The chance of RA occurrence among persons with positive anti-CCP was significantly (63.3 times [22.7-176.5]) higher than individuals with negative anti-CCP (p<0.001). Conclusion: According to our data, the chance of anti-CCP positivity in persons who have IL-10 genotype 1082 A/G is higher. Further studies are recommended to determine the relationship between IL-10 genotype 1082 G/A and RA. If such a relationship is proven, this finding as a diagnostic clue can help rheumatologists in the early detection of RA.

Fresh or Frozen Embryo Transfer in The Antagonist In Vitro Fertilization Cycles: A Retrospective Cohort Study.

BACKGROUND: Gonadotropin-releasing hormone antagonist (GnRH-ant), widely adopted protocol, is more in line with the physiological processes, and induces a shorter and more cost-effective ovarian stimulation. In order to assess the success rate of embryo transferring (ET) in the antagonist in vitro fertilization (IVF) cycles, we compared the fresh ET with the frozen ET outcomes. MATERIALS AND METHODS: In this retrospective cohort study, one hundred five cases of ET of the infertility clinic of the Besat hospital (Kurdistan, Iran) between March 2014 to March 2020 that were treated with antagonist cycle (both fresh and frozen) were analyzed. The difference between the two groups in baseline data and reproductive outcomes were evaluated using Independent sample t test, Mann-Whitney U test, Chi-squared test, and Fisher's exact test in SPSS software (version 22). RESULTS: Out of 105 cases, 48 and 57 were in the fresh and frozen ET groups, respectively. The participants age was 35.75 ± 4.9 Y. In the fresh ET group, and 33.98 ± 5.1 Y in the frozen ET group. The percentage of chemical pregnancy was 12 (25%) in the fresh ET group and 15 (26.3%) in the frozen ET group (P=0.8); Clinical pregnancy rate was 11 (22.9%) in the fresh ET group and 11 (19.3%) in the frozen ET group (P=0.6); the rate of abortion in the fresh ET group was 3 (6.3%, P=0.2), and in the frozen ET group was 8 (14%, P=0.2); and the live birth rate was 9 (18.8%) in the fresh ET group, in comparison with 7 (12.3%) in the frozen ET group (P=0.3). CONCLUSION: Not statistically significant, the percentage of chemical pregnancy and abortion were higher in the frozen ET group. The percentage of clinical pregnancy and live birth were higher in the fresh ET group.

Myo-inositol effect on pregnancy outcomes in infertile women undergoing in vitro fertilization/intracytoplasmic sperm injection: A double-blind RCT.

Background: Myo-inositol is an intracellular mediator which is involved in various aspects of reproduction in women. Objective: This study aimed to evaluate the impact of Myo-inositol on the outcomes of in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycles in infertile women. Materials and Methods: This double-blind randomized controlled trial was conducted on 70 infertile women referred to the Infertility Treatment Center, Besat hospital, Sanandaj, Iran from May 2019 to September 2019 for IVF/ICSI cycles. The participants were randomly divided into 2 intervention (n = 36) and control (n = 34) groups. The intervention group received 2000 mg of Myo-inositol and 200 mcg folic acid twice a day for 2 months and the control group received 200 mcg of folic acid twice a day for 2 months in the IVF/ICSI cycles (from the third day of cycle until the end of the second month). Finally, the number of oocytes, the quality of embryos, and the IVF/ICSI outcomes were compared between the 2 groups. Results: The mean numbers of oocytes, MII oocytes, and 2 pronuclear embryos were significantly higher in the intervention group than the control group. Also, the clinical pregnancy and live birth rates in the intervention group were significantly higher than in the controls (p = 0.04). Conclusion: The administration of Myo-inositol may increase clinical pregnancy and live birth rates by increasing the number of total and meiosis II oocytes in infertile women undergoing IVF/ICSI.

Effect of Statins on Helicobacter pylori Eradication Rate: A Systematic Review and Meta-Analysis.

Statins have been used as adjuvants to standard treatment in order to increase the eradication rates of Helicobacter pylori infection. This study aimed to summarize the results of the efficacy of adding statins to standard treatments used for the eradication of H. pylori infection. We conducted a systematic search using a comprehensive combination of keywords in PubMed/MEDLINE, Web of Science, and Scopus to retrieve relevant studies from 1990 to 2020. The estimate of pooled relative risk (RR), as the effect measure, was calculated using random effects meta-analyses in Stata 14. We finally included 5 studies (all of them were randomized controlled trials). The meta-analysis of all studies showed that the pooled RR (95% confidence interval) was 1.03 (0.64-1.68) in the random effects model, which was not statistically significant. In other words, based on our meta-analysis, the addition of statins as an adjuvant therapy to the standard treatment regimens does not increase the rate of H. pylori eradication. However, further evidence is needed to confirm this result as the number of available studies was small.

As estatinas têm vindo a ser usadas como adjuvantes à terapêutica convencional para aumentar a taxa de erradicação da infeção por Helicobacter pylori. Este estudo sumariza os resultados da eficácia de adicionar estatinas à terapêutica convencional na erradicação da infeção por Helicobacter pylori. Usando uma combinação compreensiva de palavras-chave, efetuamos uma revisão sistemática da PubMed/MEDLINE, Web of Science e Scopus de forma a encontrar estudos relevantes na área de 1990 a 2020. A estimativa do risco relativo (RR) global, como medida de eficácia, foi calculada usando o random effects meta-analyses no Stata 14. No final incluímos 5 estudos (todos ensaios randomizados e controlados). A meta-análise de todos os estudos mostrou um RR global (Intervalo confiança (IC) 95%) de 1.03 (0.64­1.68) no random effects model, que não foi estatisticamente significativo. Portanto, baseado nesta meta-análise, a adição de estatinas às duas terapêuticas convencionais mais utilizadas não aumenta a taxa de erradicação de Helicobacter pylori. Contudo, mais evidência é necessária para confirmar estes resultados já que o número de estudos disponíveis é pequeno.

Low volume polyethylene glycol combined with senna versus high volume polyethylene glycol, which regimen is better for bowel preparation for colonoscopy? A randomized, controlled, and single-blinded trial.

Background and Aims: Bowel preparation affects the quality of colonoscopy. Reaching the optimal preparation has been a challenge for years. Polyethylene glycol (PEG) is the sole FDA-approved substance for this purpose. However, patients find it unpleasant and often complain about its adverse effects. In this study, we aimed to reduce these complaints by lowering the amount of PEG and adding senna which is an herbal stimulant laxative. Methods: Four hundred and eighty-six patients were admitted for colonoscopy. Finally, 382 patients were enrolled in the study and we divided them into two groups; 186 patients were placed in which conventional high volume PEG-alone regimen was consumed and 196 patients in which low volume PEG plus senna regimen was offered. The quality of colon preparation was compared between the two groups by independent two samples t-test (or its corresponding nonparametric test), Fisher's exact, or χ 2 test in SPSS software version 22. Results: The colon preparation quality was equally efficient in the two groups as 69.36% in the high volume PEG group and 71.94% in PEG plus senna group had adequate bowel preparation (p = 0.58). Adverse effects, like nausea, bloating, headache, and sleeplessness were significantly less in the low volume PEG plus senna group. Conclusion: Besides the fact that bowel preparation by low volume PEG plus senna combination was noninferior to the conventional high volume PEG-alone regimen, the side effects were much less common with the low volume PEG plus senna regimen.
