Neutrophil to Lymphocyte Ratio and Platelet to Lymphocyte Ratio in Poststroke Depression: A Systematic Review and Meta-Analysis.

Objectives: Evidence shows that stroke-induced inflammatory responses play an essential role in the development of poststroke depression (PSD). The goal of this systematic review and meta-analysis was to critically evaluate the literature regarding the use of the neutrophil to lymphocyte ratio (NLR) as a reliable means to detect early PSD development, to help clinicians institute early interventions and improve outcomes. Methods: Electronic databases, including Web of Science, PubMed, Google Scholar, and Scopus, were searched, and eight studies were included. We assessed the certainty of the associations with GRADE methods. Results: We found that patients with PSD had higher NLR than the stroke patients with no depression (SMD = 0.51; CI 95% = 0.29-0.73, p < 0.001). Also, we found a significantly higher PLR in the patients with PSD when compared to the stroke patients with no depression (SMD = 0.66; CI 95% = 0.19-1.13, p < 0.001). Conclusion: These findings indicated that NLR and PLR could be considered inexpensive biomarkers for the prediction of PSD.

The association of apolipoprotein E (ApoE) genotype and cognitive outcomes in multiple sclerosis; a systematic review and meta-analysis.

BACKGROUND: Multiple sclerosis (MS) is a neuroinflammatory disorder commonly seen in young female adults. Cognitive impairment is one of the widespread symptoms of MS. In recent years multiple studies sought the possible risk factors for MS-related cognitive deficit. Apolipoprotein E (ApoE) genotype is one of the genetic factors which correlated significantly with cognitive status and it is a well-known risk factor for Alzheimer's Disease. In this systematic review and meta-analysis, we collected the current evidence to evaluate the association between the ApoE genotype and the cognitive outcomes in patients with MS. METHOD: Results of searches through Medline via PubMed, Scopus, and ISI web of science, as well as hand searching, were screened in the title/abstract and full-text stages. English observational studies in which the association between ApoE and cognitive outcomes, in patients with MS were included in this systematic review. Animal studies, conference abstracts, reviews, clinical trials, case reports, letters and withdrawn studies, were not included. Risk of bias was assessed using the Joanna Briggs Institute (JBI) critical appraisal tools and the meta-analysis was conducted with Comprehensive Meta-Analysis (CMA.2) software. The numbers of patients with impairment in both ApoE4+ and ApoE4- groups were utilized for the calculation of the odds ratios (ORs) with 95% confidence intervals (CI) and a 0.05 level of significance for p-value. RESULT: Out of 224 results of searching, 13 studies met the eligibility criteria and were included in our systematic review, and 5 of them were included in the quantitative synthesis. Eleven studies assessed the cognitive status of patients with MS in two groups of ApoE4+ and ApoE4- while 2 rests, reported the rate of ApoE4+ patients in cognitively impaired and non-impaired groups. The phenotype of MS was only Relapsing-remitting multiple sclerosis (RRMS) in 3 studies and in the other 10 studies, it was a mixture of RRMS, clinically isolated syndrome (CIS), and progressive MS. Most of the reports did not find a significant association between ApoE genotype and cognitive outcomes in patients with MS. Contrary to the expectations, patients in ApoE4- group were more likely to have impairment in Judgment of Line Orientation (JLO) (OR: 0.405; 95% CI: 0.173 to 0.949, p-value:0.038), while ApoE4+ patients had more rate of impairment in SRT (OR:1.901; 95%CI: 1.237 to 2.920; p-value:0.003). Appropriate identifying and dealing with cofounding factors were the most common source of bias in our included studies. CONCLUSION: ApoE may have a domain-specific association with cognitive impairment in MS patients. ApoE4 patients had more delayed responses to stimuli, but the rate of impaired visuospatial perception is lower in these patients. Based on the current evidence, there is a doubt about the clinical significance of this association.

The Efficacy of Ginseng (Panax) on Human Prediabetes and Type 2 Diabetes Mellitus: A Systematic Review and Meta-Analysis.

Results from different clinical trials on the effects of ginseng on prediabetes and type 2 diabetes (T2DM) are still inconsistent. To fill this knowledge gap, we investigated the overall effects of ginseng supplementation on improving cardiometabolic biomarkers among these patients. A systematic literature search was conducted on PubMed/MEDLINE, Scopus, Web of Science, and Cochrane library. A random-effect model was applied to estimate the weighted mean difference and 95% CI for each outcome. Overall, 20 eligible RCTs were included. Meta-analyses revealed that ginseng supplementation significantly reduced serum concentration of FPG, TC, IL-6, and HOMA-IR values. It also increased HR and TNF-α levels. Ginseng supplementation changed HOMA-IR and HDL-C significantly based on dose and changed HOMA-IR and LDL-C significantly based on study duration in a non-linear fashion. Furthermore, meta-regression analyses indicated a linear relationship between ginseng dose and absolute changes in HDL-C. Moreover, subgroup analyses showed that ginseng supplementation changed TC and LDL-C when the supplementation dose was ≥2 g/day. Our findings suggest that ginseng supplementation may be an effective strategy for improving cardiometabolic profiles in individuals with prediabetes and T2DM.

Endovascular Treatment of the Ruptured Pseudoaneurysm of Common Femoral Artery in Behcet's Disease: Report of a Case with Four Years of Follow-Up.

Behcet's disease (BD) is a vasculitic condition that affects arteries and veins of all sizes. Arterial pseudoaneurysm is a rare but life-threatening complication of BD. We reported a 41-year-old man with 20 years history of BD and 5 years history of bilateral blindness. The patient presented with sudden onset of pain and swelling in his left groin and was diagnosed with the ruptured pseudoaneurysm of the left common femoral artery (CFA), which extended into the origins of superficial and deep femoral arteries. The patient was in the active phase of BD; therefore, he was initially treated with corticosteroids and cyclophosphamide pulse therapies and subsequently underwent stent graft placement. Post stenting angiography and postprocedural ultrasonography confirmed the successful exclusion of pseudoaneurysm without any evident complication. Four years of follow-up was uneventful.

Hysterosalpingography in the assessment of proximal tubal pathology: a review of congenital and acquired abnormalities.

Tubal and peritoneal disease are the main causes of infertility. Tubal pathology can be either congenital malformation or acquired, proximal or distal, unilateral or bilateral and transient or permanent. Several imaging methods such as laparoscopy, fluoroscopy, saline infusion sonography, and hysterosalpingography (HSG) have been used in the assessment of tubal and peritoneal pathology. Although laparoscopy is the modality of choice for investigating tubal patency and pelvic structure in many infertility centers, HSG is usually the initial diagnostic method for infertility workup because of its ease of performance, accuracy, and minimal risk of complications. This method provides useful information about size, contour, and anatomy of the inner surface of the fallopian tubes and is the gold standard for evaluation of tubal lumen. Tubal and peritubal pathology show various imaging manifestations on HSG. This review illustrates the radiographic features of congenital and acquired structural abnormalities of the proximal tubal pathology and along with etiology of proximal obstruction or occlusion will be described.

Pain Perception and Side Effects During Saline Infusion Sonohysterography With a Balloon Catheter: A Randomized Comparative Study of Cervical Versus Intrauterine Catheter Placement.

OBJECTIVES: This study aimed to evaluate whether the site of the balloon placement into either the uterine cavity or cervical canal can affect the intensity of pain during sonohysterography. METHODS: In this randomized clinical trial, women who underwent saline infusion sonohysterography (SIS) were randomized to intracervical or intrauterine balloon placement between May 2012 and May 2014. The examination was scheduled at the early follicular phase of the menstrual cycle. The primary outcome measures included the degree of pain after inflation and then after deflation of the balloon catheter. Data were analyzed on the basis of the intention-to-treat principle for each woman who underwent SIS. RESULTS: A total of 300 infertile women were assigned to the treatment groups. There were no significant differences in inflation and deflation pain and the total procedure time between the 2 groups. The total volume of required saline for adequate distention of the cavity was significantly lower in the cervical group than the intrauterine group (p = .015). Nulliparous women had insignificantly more pain after the initial inflation of the balloon compared with multiparous women (p = .069). The pain score was not associated with patients' age, the volume of the saline infused, the presence of intrauterine abnormality, and the procedure time. CONCLUSIONS: Intracervical catheter placement did not reduce pain during or after SIS. However, intracervical balloon insertion requires a less-significant volume of saline compared with intrauterine placement, leading to a reduced risk of intrauterine infection and the spread of malignant endometrial cells into the peritoneal cavity at the time of the procedure.

The Effect of Vaginal Sildenafil on The Outcome of Assisted Reproductive Technology Cycles in Patients with Repeated Implantation Failures: A Randomized Placebo-Controlled Trial.

BACKGROUND: The aim of this study was to investigate the effects of vaginal sildenafil on the outcome of patients with at least two unsuccessful in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) attempts. MATERIALS AND METHODS: In this randomized placebo-controlled trial study, a total of 66 infertile women aged ≤38 years, with a history of normal ovarian reserve, two prior consecutive failed IVF/ICSI attempts, human chorionic gonadotropin (hCG) day endometrial thickness <7 mm in all prior IVF/ICSI cycles, normal endometrial appearance by either hysteroscopy, hysterosonography, or hysterosalpingography enrolled in this study. The conventional gonadotropin-releasing hormone (GnRH) protocol was used for ovarian stimulation. The patients were randomly divided into three groups: vaginal sildenafil (suppository-100 mg/daily), vaginal placebo/sildenafil (suppository-100 mg/daily), and vaginal placebo (suppository). Each patient underwent colour Doppler ultrasound on day 14 of their previous cycle to investigate any abnormalities in the uterus and adnexa. Endometrial thickness, echo pattern, uterine artery resistance, and pulsatility indices were recorded pre- and post-treatment. The primary outcome measures were implantation, chemical and clinical pregnancy rates. For data analysis, SPSS version 20 software was used. In all tests, the significance level was considered less than 0.05. RESULTS: There was no significant difference between three groups in endometrial thickness on the hCG injection day. The chemical pregnancy in women who received sildenafil (alone or in combination with placebo) showed a two-fold increase in comparison to the placebo group. This increase was clinically meaningful, but according to sample size, it was statistically non-significant. The results of our study showed that the implantation was higher in women who received placebo/sildenafil compared to the other groups. The abortion rate was not statistically significant among the groups. CONCLUSION: Vaginal sildenafil may conceivably improve chemical pregnancy rates in repeated IVF failure patients. Further randomized clinical trials using oral or vaginal sildenafil with higher sample size are recommended (Registration number: NCT03192709).

Hysterosalpingography in The Assessment of Congenital Cervical Anomalies.

Cervical abnormalities may be congenital or acquired. Congenital anomalies of the cervix are rarely isolated, and more commonly accompany other uterine anomalies. Various imaging tools have been used in the assessment of Müllerian duct anomalies (MDAs). Currently, magnetic resonance imaging (MRI) is the modality of choice for definitive diagnosis and classification of these MDAs. Hysterosalpingography is a basic tool for evaluation of infertility and allows us to detect a spectrum of anatomical malformations of the utero-cervix in the setting of MDAs. It provides good outlines of the uterine cavity and fallopian tubes, as well as the cervical canal and isthmus. However, hysterosalpingograms (HSG) cannot be performed in patients with isolated congenital maldevelopment (agenesis/disgenesis) of the cervix. This part of pictorial review illustrates the various radiographic appearances of congenital malformations of the utero-cervix with a brief overview of the embryologic features. Accurate diagnosis of such cases is considered essential for optimal treatment and categorization of each anomaly.

Hysterosalpingographic Appearances of Female Genital Tract Tuberculosis: Part II: Uterus.

Female genital tuberculosis remains as a major cause of tubal obstruction leading to infertility, especially in developing countries. The global prevalence of genital tuberculosis has increased during the past two decades due to increasing acquired immunodeficiency syndrome. Genital tuberculosis (TB) is commonly asymptomatic and it is diagnosed during infertility investigations. Despite of recent advances in imaging tools such as computed tomography (CT) scan, magnetic resonance imaging (MRI) and ultrasongraphy, hysterosalpinography has been considered as the standard screening test for evaluation of tubal infertility and as a valuable tool for diagnosis of female genital tuberculosis. Tuberculosis gives rise to various appearances on hysterosalpingography (HSG) from non-specific changes to specific findings. The present pictorial review illustrates and describes specific and non-specific radiographic features of female genital tuberculosis in two parts. Part I presents specific findings of tuberculosis related to tubes such as "beaded tube", "golf club tube", "pipestem tube", "cobble stone tube" and the "leopard skin tube". Part II will describe adverse effects of tuberculosis on structure of endometrium and radiological specific findings, such as "T-shaped" tuberculosis uterus, "pseudo-unicornuate "uterus, "collar-stud abscess" and "dwarfed" uterus with lymphatic intravasation and occluded tubes which have not been encountered in the majority of non-tuberculosis cases.

Hysterosalpingographic appearances of female genital tract tuberculosis: part I. Fallopian tube.

Female genital tuberculosis (TB) remains as a major cause of tubal obstruction leading to infertility, especially in developing countries. The global prevalence of genital tuberculosis has increased during the past two decades due to increasing acquired immunodeficiency syndrome (AIDS). Genital TB is commonly asymptomatic, and it is diagnosed during infertility investigations. Despite of recent advances in imaging tools, such as computerized tomography (CT) scan, magnetic resonance imaging (MRI) and ultrasongraphy, hysterosalpingography is still the standard screening test for evaluation of tubal infertility and a valuable tool for diagnosis of female genital tuberculosis. Tuberculosis gives rise to various appearances on hysterosalpingography (HSG) from non-specific changes to specific findings. The present pictorial review illustrates and describes specific and non-specific radiographic features of female genital tuberculosis in two parts. Part I presents specific findings of tuberculosis related to tubes such as "beaded tube", "golf club tube", "pipestem tube", "cobble stone tube" and "leopard skin tube". Part II describes adverse effects of tuberculosis on structure of endometrium and radiological specific findings such as "dwarfed" uterus with lymphatic intravasation and occluded tubes, "T-shaped" tuberculosis uterus, "pseudounicornuate" uterus and "Collar-stud abscess", which have not been encountered in the majority of non-tuberculosis cases.

Evaluation of intrauterine structural pathology by three-dimensional sonohysterography using an extended imaging method.

Structural intrauterine abnormalities are an important cause of infertility, recurrent pregnancy loss and bleeding or pain associated with a poor reproductive outcome. Various diagnostic methods have been applied to detect these lesions such as hysterosalpingography, hysteroscopy and sonohysterography. More recently, three-dimensional extended imaging (3DXI) provides the ability to obtain sequential sections of acquired volume scans in A, B and C planes. Here, we briefly discuss the technique of saline infusion sonography, followed by a review of sonohysterographic characteristics of intracavitary pathologies with more focus on some definitions and measurements.

Application of 3D Ultrasonography in Detection of Uterine Abnormalities.

Structural pathologies in the uterine cavity such as müllerian duct anomalies (MDAs) and intrauterine lesions (fibroids, polyps, synechiae) may have important roles in subinfertility, implantation failure and pregnancy outcome. Various imaging modalities such as hysterosalpingography (HSG), sonography, laparoscopy and hysteroscopy are used in the evaluation of MDAs and intrauterine lesions. Recently, three-dimensional ultrasound (3DUS) has been introduced as a non-invasive, outpatient diagnostic modality. With increased spatial awareness, it is superior to other techniques used for the same purpose.

Comparing intramuscular progesterone, vaginal progesterone and 17 -hydroxyprogestrone caproate in IVF and ICSI cycle.

BACKGROUND: Supplementation of luteal phase with progesterone is prescribed for women undergoing routine IVF treatment. OBJECTIVE: The objective of this study was to compare the efficacy of three types of progesterone on biochemical, clinical and ongoing pregnancy rates and abortion and live birth rates. MATERIALS AND METHODS: A prospective randomized study was performed at Royan Institute between March 2008 and March 2009 in women under 40 years old, who use GnRH analog down-regulation. One hundred eighty six patients in three groups were received progesterone in oil (100 mg, IM daily), intravaginal progesterone (400 mg, twice daily) and 17-α hydroxyprogestrone caproate (375mg, every three days), respectively. RESULTS: Final statistical analysis after withdrawal of some patients was performed in 50, 50 and 53 patients in group 1, 2 and 3 respectively. No differences between the groups were found in baseline characteristics. No statistical significance different was discovered for biochemical, clinical and ongoing pregnancies. Although the abortion rate was statistically higher in group 1 (p=0.025) the live birth rate was not statistically significant between the three groups. CONCLUSION: The effects of three types of progesterone were similar on pregnancies rate. We suggest the use of intravaginal progesterone during the luteal phase in patients undergoing an IVF-ET program because of the low numbers of abortions, and high ongoing pregnancy rates.

Dizygotic twin pregnancy with a complete hydatidiform mole and a coexisting viable fetus.

Coexistence of a viable fetus with a hydatidiform mole is a rare condition and the diagnosis is very important because of the risk of developing severe complications in pregnancy. The management of these pregnancies is optional, although accurate and great care is required to find early signs of maternal or fetal complications.Hereby we report a case of dizygotic twin pregnancy with a complete mole and coexisting fetus that resulted in a live neonate.

Effect of low-dose aspirin therapy on implantation rate in women undergoing in-vitro fertilization cycles.

OBJECTIVE: To determine the effect of low-dose aspirin on ovarian response, implantation and pregnancy rates in patients undergoing in-vitro fertilization (IVF) cycles. METHODS: We performed a randomized analysis of 145 infertile women with a mean+/-SD age of 29.6 +/- 4.47 years who underwent cycles of IVF. Patients received 100 mg of aspirin (n=72) or placebo (n=73) daily. This study was conducted in Royan Institute, Tehran, Iran from April 2002 to January 2004. Aspirin was started on the 21st of their preceding menstrual cycle and it was continued until menstruation or a negative pregnancy test. Pregnant women received the medication until 12 weeks of pregnancy. The main outcome measures were number of follicles >or=15 mm, number of oocytes retrieved, serum E2 levels, cancellation rate, Ovarian Hyperstimulation Syndrome (OHSS) occurrence, number of embryos transferred, and implantation and pregnancy rates. RESULTS: There were statistically significant differences between the treatment group and the control group in the number of follicles (7.4 +/- 4.1 versus 9.0 +/- 4.8) and OHSS occurrence (5.6% versus 23.3%) but not in the other measures. CONCLUSION: The addition of aspirin low dose (100 mg/daily) to the standard long protocol for oocyte retrieval did not improve implantation and pregnancy rates in unselected patients undergoing IVF cycles.

Evaluation of ovulation induction protocols for poor responders undergoing assisted reproduction techniques.

OBJECTIVE: To compare 3 stimulation protocols in poor ovulation responders undergoing in-vitro fertilization (IVF). METHODS: The study was a randomized, prospective clinical trial from June 2003 to July 2004, in Royan Institute, Tehran, Iran. One hundred and fifty-four patients, who had poor responses to ovulation induction in at least one previous IVF attempt, were randomly divided into 3 groups. In the first group, human menopausal gonadotropin (HMG) was administered from day 3 of the cycle at a dose rate of 150 IU/day. In the second group, gonadotropin-releasing hormone (GnRH) agonist was started at a dose rate of 800 microg/day by nasal spray or 500 microg/day subcutaneously in the mid-luteal phase, followed by a standard HMG dose after pituitary down regulation was confirmed. In the third group, clomiphene at a dose rate of 100 mg/day was given from day 3 and HMG from day 6. Our main outcomes were number of mature oocytes, cancellation rate, number of HMG ampoules used and incidence premature luteinizing hormone (LH) surge. RESULTS: There was a high incidence of premature LH surge in all groups except in the GnRH group (p=0.0001) and there were significant differences between groups in HMG requirements (p=0.004). There were no significant differences between groups in number of mature oocytes recovered and cancellation rate. CONCLUSION: Results showed no advantage in the use of GnRH agonist compared to the older regimens of clomiphene plus HMG and HMG alone. The cancellation rate was similar for 3 protocols and HMG requirement was higher with the use of GnRH agonist. The treatment of poor responders in assisted reproductive technologies remains a challenge.
