Nigella sativa extract in the treatment of depression and serum Brain-Derived Neurotrophic Factor (BDNF) levels.

Background: Here, we aimed to investigate the therapeutic effects of Nigella sativa extract on serum brain-derived neurotrophic factor (BDNF) and depression score in patients with depression. Materials and Methods: This clinical trial was performed in 2021 in the hospitals of military forces in Tehran on 52 male patients with major depressive disorder treated with sertraline. We used the Depression, Anxiety, and Stress Scale-21 Items (DASS-21) questionnaire to assess the patients. Serum BDNF levels were measured by the enzyme-linked immunosorbent assay. Patients were then divided into two groups receiving 1000 mg N. sativa oil extract, daily, and placebo. Both groups received sertraline for at least 3 months. DASS-21 questionnaire and serum BDNF levels were measured after 10 weeks. Results: After treatments, we observed significantly decreased DASS-21 score (-11.24 ± 5.69) in the intervention group (P < 0.001) and placebo (-2.72 ± 6.19, P = 0.032), but patients in the intervention group had significantly lower scores (50.1 ± 6.8 vs. 58.2 ± 5.6, respectively, P < 0.001). Furthermore, patients in the intervention group had significantly decreased depression score (-5.5 ± 2.47, P < 0.001) and lower scores compared to the placebo (P < 0.001) (18.6 ± 2.7 vs. 23.4 ± 2.1 in intervention and placebo, respectively). We also observed significantly increased BDNF levels in the intervention group after the treatments (6.08 ± 3.76, P < 0.001) compared to the placebo group (29.4 ± 3.6 vs. 24.9 ± 2.1, P < 0.001). Serum BDNF levels had also significant reverse correlations with DASS-21 score (r = -0.35, P = 0.011) and depression score (r = -0.45, P = 0.001). Conclusion: The use of N. sativa resulted in decreased depression score and increase in serum BDNF levels that indicate the importance and efficacy of this drug.

Pregnancy-related complications in patients with endometriosis in different stages.

BACKGROUND: Endometriosis is one of the most common and costly diseases among women. This study was carried out to investigate pregnancy outcomes in women with endometriosis because of the high prevalence of endometriosis in reproductive ages and its effect on pregnancy-related complications outcomes. METHODS: This was a cross-sectional study performed on 379 pregnant women with endometriosis who were referred to the endometriosis clinic of the Avicenna Infertility Treatment Center from 2014 to 2020. Maternal and neonatal outcomes were assessed for the endometriosis group and healthy mothers. The group with endometriosis was further divided into two groups: those who underwent surgery and those who either received medication alone or were left untreated before becoming pregnant. The analysis of the data was done using SPSS 18. RESULTS: The mean age of the patients was 33.65 ± 7.9 years. The frequency of endometriosis stage (P = 0.622) and surgery (P = 0.400) in different age groups were not statistically significant. The highest rates of RIF and infertility were in stages 3 (N = 46, 17.2%) (P = 0.067), and 4 (N = 129, 48.3%) (P = 0.073), respectively, but these differences were not statistically different, and the highest rate of pregnancy with ART/spontaneous pregnancy was observed in stage 4 without significant differences (P = 0.259). Besides, the frequency of clinical/ectopic pregnancy and cesarean section was not statistically different across stages (P > 0.05). There is no significant relationship between endometriosis surgery and infertility (P = 0.089) and RIF (P = 0.232). Most of the people who had endometriosis surgery with assisted reproductive methods got pregnant, and this relationship was statistically significant (P = 0.002) in which 77.1% (N = 138) of ART and 63% (N = 264) of spontaneous pregnancies were reported in patients with endometriosis surgery. The rate of live births (59.4%) was not statistically significant for different endometriosis stages (P = 0.638). There was no stillbirth or neonatal death in this study. All cases with preeclampsia (N = 5) were reported in stage 4. 66.7% (N = 8) of the preterm labor was in stage 4 and 33.3% (N = 4) was in stage 3 (P = 0.005). Antepartum bleeding, antepartum hospital admission, preterm labor, gestational diabetes, gestational hypertension, abortion, placental complications and NICU admission were higher in stage 4, but this difference had no statistical difference. CONCLUSION: Endometriosis is significantly correlated with infertility. The highest rates of RIF and infertility are observed in stages 3 and 4 of endometriosis. The rate of pregnancy with ART/spontaneous pregnancy, preterm labor, preeclampsia and pregnancy-related complications is higher in stage 4. Most of the people who had endometriosis surgery with assisted reproductive methods got significantly pregnant. Clinical/ectopic pregnancy, cesarean sections, and live birth were not affected by the endometriosis stages.

A literature review on the imaging methods for breast cancer.

Breast cancer will be easier and more effective to treat if detected early. Breast cancer is assessed and detected using imaging as a primary approach. The capacity to diagnose breast cancers is continually improving thanks to developments in imaging technologies. However, some of these enhancements have been linked to delays in the initiation of treatment procedures of breast cancer. Overall, cancer management relies heavily on imaging procedures such as screening and symptomatic disease management. Mammography, which is considered the gold standard, and breast ultrasonography are employed as routine imaging modalities. Previous research has shown that, despite recent developments, no single imaging modality can detect and characterizing majority of breast lesions. Various imaging methods and their uses in diagnosing and caring the breast cancer are discussed in this study.

Investigating the role of susceptibility weighted imaging for assessment of ischemic penumbra with respect to Venus blood flow in ischemic stroke patients.

INTRODUCTION: Susceptibility weighted imaging can be used to study intracranial venous blood arteries based on the paramagnetic sensitivity of blood discharged by oxygen (SWI). Significant hypotensive drainage channels have been discovered in the ischemic tissue of the brain, which have been recognized by SWI. The compliance or non-compliance between the variation in venous drainage of ischemic brain tissue by SWI and diffusion limitation. MATERIAL AND METHODS: This cross-sectional study was conducted in 2019 on 20 patients (15 men and 5 females) who were assigned to the Ghaem Hospital MRI Institute in Rasht, Iran. RESULTS: Infarction has been detected in a total of 20 vascular regions. The caliber of the sulcal and intramedullary veins, on the other hand, was increased in 80 percent and 65 percent of the infarcted regions, respectively. In 45 percent of the vascular regions, a match between SWI and diffusion-weighted magnetic resonance imaging (DWI) was detected, mismatch was detected in two; follow-up revealed infarct progression. CONCLUSIONS: Significant data on critically perfused cerebral cortex with possibility of infarction growth was focused on in elevated SWI investigations, contributing to SWI as a worthy MR implies that could be attached as complementary protocols to neuroimaging techniques for acute ischemia, according to the findings of this study.

Comparison of the effect of topiramate versus gabapentin on neuropathic pain in patients with polyneuropathy: A randomized clinical trial.

BACKGROUND: Neuropathic pain is one of the most common complaints of neurologic clinics. Neuropathic pain is common and important and has inappropriate complications, and despite their importance, there is no effective treatment for them. OBJECTIVE: Because of the importance of neuropathic pain and safe and effective treatment, in this study, we determined the effect of topiramate versus gabapentin in patients with neuropathic pain. METHODS: In this randomized clinical trial, 30 patients with pain attributed to neuropathy who had at least one month of neuropathic pain in one area, were randomized to receive either gabapentin, titrated from 300 mg/day to a maximum of 900 mg/day or topiramate, titrated from 50 mg/day to a maximum of 100 mg/day after a 4-week period in the neurology clinic of Imam Khomeini Hospital of Urmia city, Iran in 2015. Complication, drug tolerance rate and pain were investigated. The pain was measured on visual analog scale (VAS). The data were analyzed by SPSS version 18, and using descriptive statistics, t-test, and ANOVA. RESULTS: In patients treated by gabapentin, the primary pain score was 74.33±10.29, this score decreased to 49.46±11.41 and 29.93±11.92 in the second and fourth week after intervention with gabapentin. In topiramate treated patients, the primary score was 76.00±9.69. It decreased to 54.33±10.31 and 34.20±6.09 at the same time. There were no significant differences between both groups in terms of average reduction of pain intensity [gabapentin group (59.73%) compared with topiramate (55%) (p=0.48)]. In the present study, the only complication reported in patients treated by gabapentin was drowsiness, but other uncommon side effects were nausea and dizziness. CONCLUSION: This study showed that both gabapentin and topiramate reduce pain. Topiramate can also be a good alternative choice, if gabapentin has side effects for patients and it cannot be tolerated, topiramate can be a good replacement. TRIAL REGISTRATION: The trial was registered at the Thai Registry of Clinical Trials (http://www.clinicaltrials.in.th) with the TCTR ID: TCTR20170615001.
