Abstract
Background and Aims Transient neurologic syndrome (TNS) is a postoperative pain in the back and buttock that can occur after spinal anesthesia. The spinal needle design may have an impact on the occurrence of TNS. We decided to compare the incidence of TNS and related factors between two spinal needle types. Methods In this randomized clinical trial, 150 patients aged 18-60 years and American Society of Anesthesiologists (ASA) physical status I who underwent lower abdomen or lower extremity surgeries with spinal anesthesia and supine position were enrolled. They were randomly divided into two groups (25 G Quincke or Sprotte needle) with 0.5% bupivacaine (12.5 mg). After the operation, the patients were asked to report any pain in the lower back, buttock, and thigh areas. A Visual Analog Scale (VAS) was also used to record the severity of the pain. Results Overall, 45 patients developed TNS. Twenty-nine patients in the Sprotte group (38.7%) and 16 patients in the Quincke group (21.3%) developed TNS (p = 0.75). More patients in the Sprotte group (25.3%) had severe pain (VAS score of 8-10) when compared with the Quincke group (6.7%). There was no significant difference in TNS symptoms duration between the two groups. In about half of patients (51.9%) in the Sprotte group and 57.3% of patients in the Quincke group, the symptoms resolved after 2-3 h. Conclusion Although the incidence of TNS did not differ significantly, patients for whom a Sprotte spinal needle had been used had more severe pain. This suggests that the Quincke needle caused less severe pain.

Abstract
Coronavirus disease (COVID-19) affects both the respiratory system and the body as a whole. Natural molecules, such as flavonoid quercetin, as potential treatment methods to help patients combat COVID-19. The aim of this systematic review and meta-analysis is to give a comprehensive overview of the impact of quercetin supplementation on inflammatory factors, hospital admission, and mortality of patients with COVID-19. The search has been conducted on PubMed, Scopus, Web of Science, EMBASE, and the Cochrane Library using relevant keywords until August 25, 2023. We included randomized controlled trials (RCTs) comparing COVID-19 patients who received quercetin supplementation versus controls. We included five studies summarizing the evidence in 544 patients. Meta-analysis showed that quercetin administration significantly reduced LDH activity (standard mean difference (SMD): -0.42, 95% CI: -0.82, -0.02, I 2 = 48.86%), decreased the risk of hospital admission by 70% (RR: 0.30, 95% CI: 0.14, 0.62, I 2 = 00.00%), ICU admission by 73% (RR: 0.27, 95% CI: 0.09, 0.78, I 2 = 20.66%), and mortality by 82% (RR: 0.18, 95% CI: 0.03, 0.98, I 2 = 00.00%). No significant changes in CRP, D-dimmer, and ferritin were found between groups. Quercetin was found to significantly reduce LDH levels and decrease the risk of hospital and ICU admission and mortality in patients with COVID-19 infection.

Abstract
Patients with chronic renal failure, many of which treated with hemodialysis, present a high prevalence of impaired muscle strength which suggest that muscle mass parameters may be used as markers for changes in muscle in these patients. Measurement of handgrip strength (HGS) is a common, simple, and quick measure of muscle function an indicator of overall muscle strength which has been associated with physical activity and several anthropometric traits. Intercellular adhesion molecule-1 (ICAM-1) and insulin-like growth factor-1 (IGF-1) are biochemical markers associated with inflammatory processes which are a common consequence of dialysis. Additionally, hemodialysis patients frequently present signs of malnutrition and depression. This cross-sectional study aimed to evaluate if muscle and biochemical markers could be used to predict the risk of depression in hemodialysis patients. Several anthropometric parameters, nutrient intake, depression state and the serum levels of ICAM-1 and IGF-1 were determined and Pearson's correlation coefficient and/or Spearman's correlation coefficient were used to test the correlation between them. Our results do not show a correlation between HGF, IGF-1 and ICAM-1 with the depression status of the patients, but mid-arm muscle circumference (MAMC) was statistically and positively correlated with depression. Additionally, ICAM-1 levels were negatively correlated with HGS, MAMC, and IGF-1. Overall, the results of the present study suggest that HGS may be used as an indicator of cardiovascular diseases and MAMC may be a good predictor of the level of depression in hemodialysis patients, although further studies are required.

Abstract
BACKGROUND Omega-3 fatty acids (omega-3 FAs) have attracted the attention of researchers because of their influence on circulatory levels of brain-derived neurotrophic factor (BDNF). Our objective was to review systematically and Meta-analyze randomized controlled trials (RCTs) to assess the effects of omega-3 FAs supplementation on serum BDNF concentration. METHODS Scopus, PubMed, Web of Science, and Cochrane Library were systematically searched until April 2023. The Cochrane risk of bias assessment tool was utilized to evaluate the quality of the studies. A random-effects model was employed to estimate the overall effect size of BDNF levels, using the Standard Mean Difference (SMD) and a 95% confidence interval (CI). The heterogeneity among the studies was assessed using chi-squared and I2 statistics. RESULTS A total of 12 studies involving 587 subjects were included. The supplementation of PUFA was found to be associated with a significant increase in serum levels of BNDF in the group receiving the supplements, as compared to the placebo group (SMD: 0.72 pg/mL, 95% CI: 0.28, 1.15; P < 0.001) (I2 = 84.39%, P < 0.001). Sub-group analyses revealed similar findings in trials with fewer than 10 weeks, which utilized both animal (fish oil) and herbal (flaxseed) forms of omega-3 supplements with a high daily dosage of 2000mg. CONCLUSION The present systematic review and meta-analysis indicate the efficacy of omega-3 FAs in increasing the serum concentration of BDNF. Therefore, omega-3 FAs should be prioritized as agents for increasing BDNF in interventions.

Abstract
Almond intake may be correlated with improvements in several cardiometabolic parameters, but its effects are controversial in the published literature, and it needs to be comprehensively summarized. We conducted a systematic search in several international electronic databases, including MEDLINE, EMBASE, Scopus, Web of Science, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov until April 2021 to identify randomized controlled trials that examined the effects of almond consumption on cardiometabolic risk factors, inflammatory markers, and liver enzymes. Data were pooled using the random-effects model method and presented as standardized mean differences (SMDs) with 95% confidence intervals (CIs). Twenty-six eligible trials were analyzed (n = 1750 participants). Almond intake significantly decreased diastolic blood pressure, total cholesterol, triglyceride, low-density lipoprotein (LDL), non-high-density lipoprotein (HDL), and very LDL (p < 0.05). The effects of almond intake on systolic blood pressure, fasting blood glucose, insulin, hemoglobin A1c, homeostatic model assessment of insulin resistance, C-peptide, alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transferase, C-reactive protein (CRP), hs-CRP (high sensitivity C-reactive protein), interleukin 6, tumor necrosis factor-α, ICAM (Intercellular Adhesion Molecule), VCAM (Vascular Cell Adhesion Molecule), homocysteine, HDL, ox-LDL, ApoA1, ApoB, and lipoprotien-a were not statistically significant (p > .05). The current body of evidence supports the ingestion of almonds for their beneficial lipid-lowering and antihypertensive effects. However, the effects of almonds on antiinflammatory markers, glycemic control, and hepatic enzymes should be further evaluated via performing more extensive randomized trials.

Abstract
Recently, the use of synbiotics for managing various diseases has dramatically increased. Synbiotics have been shown to be a good approach to influence the composition of the gut microbiota with positive health effects. Management of type 2 diabetes mellitus (T2DM) complications is one of the reasons for the ingestion of synbiotics and so the aim of the current study was to determine the effects of synbiotic bread intake on markers of lipid profile in T2DM patients. One hundred T2DM patients (age between 20 and 60 years) were randomly assigned to four groups to consume different types of synbiotic bread, three times/day, for 8 weeks: "synbiotic + lactic acid" (n = 25; IV), "synbiotic" (n = 25; III), "lactic acid brad" (n = 25; II), or "control" (n = 25; I). The measured outcomes included anthropometric characteristics, glycemic control parameters, blood lipids, and apolipoproteins. The consumption of "synbiotic + lactic acid bread" (group IV) and "lactic acid bread" (group II) led to a significant decrease in total cholesterol (TC) and glycated hemoglobin (HbA1c) compared to the "control bread." The HbA1c levels were also significantly lower when compared to group II. Additionally, apolipoprotein A (Apo A1) levels were significantly decreased in group IV, compared to control and other groups (post hoc analysis). No significant differences between groups were observed for triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and apolipoprotein B100 (Apo B100) levels. The observed results show that the synbiotic bread (with or without lactic acid) promoted a decrease in total cholesterol (TC) and Apo A1 in diabetic patients when consumed daily for 8 weeks.

Abstract
Great advancements in modern field-reversed configuration (FRC) experiments motivated the development of a 14-chord three-wave far infrared (FIR) laser interferometry and polarimetry diagnostic system, which can provide simultaneous high temporal resolution measurements of density and Faraday rotation profiles with high accuracy. The unique challenges facing FIR diagnostics in high beta FRC plasmas are the extremely small (<0.5°) Faraday rotation angles, and severe laser beam refraction effects due to high density gradient and choice of long wavelength. The diagnostic system design and development are described with methods to overcome the challenges, and initial experimental data are also presented.

Abstract
Turbulent curtains of smoke rise initially as flat plumes and, above a certain height, they become round plumes. The same evolution of cross-sectional shape is exhibited by jets issuing from flat nozzles. Here we predict based on principle that all such flows should evolve their cross-sectional shapes from flat to round (and not the other way) at a critical distance downstream, which is predictable. The principle is that the prevailing flow architecture provides greater access to the flow of momentum from the moving core (plume, jet) to the still surroundings. For turbulent plumes and jets, the transition distance scales with the long dimensions (L) of the two-dimensional (flat) heat sources and nozzles that drive them. For laminar jets, the transition distance scales with L Re, where Re is the Reynolds number based on nozzle velocity and the smaller dimension of the nozzle cross section. These predictions are confirmed by full numerical experiments of the three-dimensional flow fields of turbulent and laminar jets covering the Re range 10–104.

Abstract
The aim of the present study was to isolate and characterize the cellulose-degrading bacteria from the gut of the local termite, Microcerotermes diversus (Silvestri), inhabiting the Khuzestan province of Iran. The microorganisms capable of growing in the liquid medium containing cellulose as the only source of carbon were isolated and their cellulolytic activity on CMC-containing media was confirmed by the congo red clearing zone assay. The isolates were identified based on biochemical characteristics and the phylogenetic analysis of 16S rRNA gene fragments. The results of the present study show that three cellulose-degrading bacteria isolated from local termite guts belonged to the genera Acinetobacter, Pseudomonas and Staphylococcus and four cellulose-degrading bacteria belonged to Enterobacteriaceae and Bacillaceae families. Several isolates recovered from separate termite Microcerotermes diversus samples closely clustered in phylogenetic trees indicating high similarity and the abundance of particular cellulolytic strains. Bacillus B5B and Acinetobacter L9B hydrolyzed cellulose faster than the other isolates (with CMCase activity of 1.47 U/mL and 1.22 U/mL, respectively). The stability of CMCase produced by Bacillus B5B over a broad range of pH and high temperature indicated that the enzyme may be of great commercial value.

Abstract
OBJECTIVE To compare the effects of tibolone with those of conventional hormone replacement therapy on climacteric symptoms and sexual function in postmenopausal women. MATERIALS AND METHODS In a randomized, controlled trial, 140 postmenopausal women were allocated into three groups. Of the subjects included, 47 women received 2.5 mg tibolone + one Cal+D tablet (500 mg calcium and 200 IU vitamin D) daily; 46 women received 0.625 mg conjugated equine estrogen + 2.5 mg medroxyprogesterone (CEE/MPA) + one Cal+D tablet daily; and 47 women received only one Cal+D tablet as the control group. The Greene Climacteric Scale (GCS) questionnaire was used to detect the efficacy of treatment on climacteric symptoms. Rosen's Female Sexual Function Index (FSFI) was used for sexual function evaluation. Sex hormone binding globulin (SHBG), free estradiol index (FEI) and free testosterone index (FTI) were measured before and after treatment. The women were followed up for 6 months RESULTS After treatment, all subscores in the GCS improved in the tibolone and CEE/MPA groups (p < 0.01), except the sexual subscore in the CEE/MPA group, compared with baseline. There were significant differences in the FSFI in the tibolone and CEE/MPA groups in comparison to the control group after treatment. Tibolone, in comparison to CEE/MPA, significantly lowered SHBG levels and increased the FTI and FEI and improved the desire, arousal and orgasm sexual domains of the FSFI (p < 0.001). CONCLUSION Tibolone may be an alternative to conventional hormone replacement therapy in the treatment of climacteric symptoms and sexual dysfunction in postmenopausal women.

Abstract
OBJECTIVE To compare the effects of tibolone with those of continuous combined hormone replacement therapy (HT) on body composition in postmenopausal women. METHODS One hundred and fifty postmenopausal women were enrolled in a randomized, controlled trial to compare the effects of tibolone with continuous combined HT on body composition. Patients were randomly allocated into three groups and followed for 9 months. Of the subjects included, 50 women received 2.5 mg tibolone plus one Cal+D tablet (500 mg calcium and 200 IU vitamin D) daily, 50 women received 0.625 mg conjugated equine estrogen and 2.5 mg medroxyprogesterone acetate (CEE/MPA) plus one Cal+D tablet daily, and the rest (50 women) received only one Cal+D tablet and served as a control group. Body composition was evaluated with measurements of body mass index (BMI), weight, waist-to-hip ratio (WHR), fat mass and fat-free mass (FFM) before and after the intervention. Measurements of body fat mass percentage, fat mass, body fat-free mass percentage and fat-free mass (FFM) were assessed by measurement of skin-fold thickness. RESULTS Tibolone significantly increased weight, BMI and FFM and decreased WHR after the treatment in comparison with baseline (p < 0.05). However, only weight and BMI increased significantly in the CEE/MPA group after the treatment (p < 0.05). There were significant increases in weight, BMI and fat mass in the control group after 9 months. In the comparison of the parameters after the treatment between the three groups, tibolone significantly increased FFM compared with the control and CEE/MPA groups (p < 0.01). CONCLUSIONS The effect of tibolone on body composition is favorable and therefore tibolone may be regarded as an alternative to continuous combined hormone therapy in postmenopausal women.

Abstract
BACKGROUND Hot flashes affect as many as 75% of menopausal women. Estrogen reliably reduces the severity of hot flashes and remain the single most effective treatment. Today, however, more and more women are seeking alternatives. Instead of hormonal therapy, women are turning to vitamins, and other over-the-counter products for relief from hot flashes. This study was undertaken to assess the effect of vitamin E on hot flashes. METHOD A placebo double blind-controlled trial was conducted. After 1 week baseline period, the enrolled patients (n = 51) received placebo (identical in appearance to vitamin E softgel) daily for 4 weeks, followed by 1 week wash out and 400 IU vitamin E (softgel cap) daily for the next 4 weeks. Diary was used to measure hot flashes before and at the end of the study. RESULT There were statistical significant differences in hot flashes severity score (2.37 +/- 0.74, 1.80 +/- 0.87) and their daily frequency (5.00 +/- 3.34, 3.19 +/- 2.74) after the treatments between the placebo and vitamin E therapies (p < 0.0001). CONCLUSION Based on our trial, vitamin E is recommended for the treatment of hot flashes.

Abstract
OBJECTIVE To study the effect of iron supplementation on pregnancy outcome in pregnant women with haemoglobin (Hb) > or = 13.2 g/dl. DESIGN A randomised, double-blind, placebo-controlled trial. SETTING Routine health services. POPULATION Seven hundred and twenty-seven pregnant women with Hb > or = 13.2 g/dl in the early stage of the second trimester. METHODS Each woman took one ferrous sulphate [DOSAGE ERROR CORRECTED] tablet (150 g tablet, containing 50 mg of elemental iron) [DOSAGE ERROR CORRECTED] daily in the case group (n = 370) or placebo in the control group (n = 357) throughout pregnancy. MAIN OUTCOME MEASURES Pregnancy outcome. RESULTS While there were no significant differences in demographic and obstetric characteristics between the two groups before any intervention, small-for-gestational-age birth rate and the number of women with hypertension disorder increased significantly in the case group in comparison with the control group (57 [15.7%] versus 36 [10.3%], P = 0.035, 10 [2.7%] versus 3 [8%], P = 0.05, respectively). CONCLUSIONS Our finding proves that routine iron supplementation in nonanaemic women is not rational and may be harmful.

Abstract
OBJECTIVE The effect of the timing of admission in labor unit on the method of delivery was evaluated in a cohort study. METHOD Four hundred and sixty six low-risk nulliparous women who were admitted in the labor unit in latent phase (group 1) were compared with 329 parturient women who were admitted in the active phase (group 2) to determine rate of and reasons for cesarean section, cervical dilation at the time of cesarean, and the rate of labor augmentation. RESULT The number of cesarean deliveries in group 1 was greater than that in the group 2 (301 vs 80, p<0.0001 ). The main reason for cesarean section in group 1 was dystocia, and in 2, fetal distress. The rate of cesarean section in the women who were augmented was greater in group 1 than in group 2 (54% vs 23%, p<0.0001). CONCLUSION Later admission in labor increases the rate of spontaneous vaginal delivery in low risk nulliparous women.

Abstract
The aim of the study was to determine whether the order of cell collection (ie, obtaining either endocervical first or ectocervical cells first) has an effect on the quality of the Papanicolaou smear. 1129 smears were obtained using an Ayre spatula and an endocervical brush. In 564 cases, the endocervical brush was used first, and in 565 cases, the spatula was used first. The number of smears obscured by blood, the smears without endocervical component, and the smears with poor fixation were compared between the two groups. More smears were partially obscured by blood when brush was used first (78, 13.8% compared with 48, 8.5%, P = 0.004). No endocervical component was found in seven (1.2%) smears from the brush-first group compared with five (0.9%) of the spatula-first group, which is an insignificant difference. There were no significant differences in the number of poor-fixated smears, too-thick smears, and satisfactory smears but limited by inflammation between the two methods. The quality of the Papanicolaou smear can be improved by using the Ayre spatula first followed by the endocervical brush. Fewer smears will be contaminated by blood which may result in more squamous intraepithelial lesions being detected.

Abstract
OBJECTIVE To determine whether levels of human beta-chorionic gonadotropin hormone (beta-hCG) in cervicovaginal secretions can predict the labor process. METHODS A total of 150 women admitted in active labor to the urgent delivery unit of a university hospital were enrolled in a prospective study. The beta-hCG level of each woman's cervicovaginal secretions was measured by radioimmunoassay on admission; then, beta-hCG levels were compared between 2 groups of 35 women, one in whom labor progressed normally and another in whom augmentation of labor with oxytocin was required. RESULTS There were significant differences in beta-hCG levels of cervicovaginal secretions between the spontaneous delivery group and the augmentation of labor group (130.72+/-64.51 mU/mL vs. 93.9+/-65.29 mU/mL) (P<0.05). A receiver-operating characteristic (ROC) curve analysis showed that the optimal cut-off value was 82 mU/mL, with a sensitivity of 66% and a specificity of 60%. CONCLUSION beta-chorionic gonadotropin hormone levels were significantly higher in the cervicovaginal secretions of women whose labor was progressing normally than in those who required augmentation of labor.

Abstract
OBJECTIVE To study the effect of vitamin E in the treatment of primary dysmenorrhoea. DESIGN A randomised, double-blind, placebo-controlled trial. SETTING A secondary school in Tehran, Iran. POPULATION Two hundred and seventy-eight girls aged 15-17 years who suffered from primary dysmenorrhoea. METHODS Participants were given 200 units of vitamin E or placebo twice a day, beginning two days before the expected start of menstruation and continued through the first three days of bleeding. Treatment was continued over four consecutive menstrual periods. MAIN OUTCOME MEASURES The severity and duration of pain, and the amount of menstrual blood loss, at two and four months. A visual analogue scale (VAS) was used to record pain, and a validated Pictorial Blood Loss Assessment Chart (PBLAC) to measure menstrual loss. RESULTS In the vitamin E group, pain severity was lower with vitamin E at two months (median VAS score 3 vs 5, P > 0.001) and four months (0.5 vs 6, P > 0.001), pain duration was shorter at two months (mean 4.2 [7.1] hours vs 15 [17], P > 0.001) and at four months (1.6 [4.0] hours vs 17 [18] hours, P > 0.0001), and blood loss assessed by PBLAC score was lower at two months (54 [31] vs 70 [40], P > 0.0001) and at four months (46 [28] vs 70 [37], P > 0.0001). CONCLUSION Vitamin E relieves the pain of primary dysmenorrhoea and reduces blood loss.

Abstract
This was a comparative study of side effects and acceptability of low-dose pills administered by the oral and vaginal rout. In an experimental clinical trial study, undesirable side effects of nausea, dysmenorrhea, breast tenderness, gastrointestinal disorders, vertigo, headache, and breakthrough bleeding (BTB) were studied. The participants of the case and the control groups were the same women. The side effects were compared in 143 women using contraceptive pill containing 150 microg levonorgestrel and 30 microg ethinyl estradiol by vaginal and oral route. The efficacy and acceptability were evaluated. The side effects among the patients who used the contraceptive pills orally were significantly higher than among those who used the vaginal route (p < 0.0001). BTB occurred more often with the oral route, but there was no significant difference between their incidences (p = 0.267). Most participants in this study expressed a high level of acceptability with the vaginal route. There was only one unwanted pregnancy, which occurred when the participant used the contraceptive pill vaginally, but used it incorrectly. Using the contraceptive pill administered by vaginal route is a safe method with fewer side effects and more acceptability when compared with the oral route.

Abstract
OBJECTIVE This study was designed to determine the effect of garlic tablet (Garlet) on plasma lipids, and platelet aggregation and the efficacy of this treatment in the prevention of preeclampsia. STUDY DESIGN In a randomized, single-blind, placebo-controlled study, 100 primigravidas with positive roll-over test were treated with daily doses of 800mg Garlet/day (n=50) or 800mg/day placebo (n=50) during the third trimester of pregnancy. Serum total cholesterol, LDL-and HDL-cholesterol, triglyceride, and platelet aggregation were measured before and after the treatment. Blood pressure, weight, and edema were also examined during the entire study period. RESULTS In the case group, there was no significant difference in the means of total cholesterol, HDL, LDL, and triglyceride before and after the experiment. Furthermore, the inhibition of platelet aggregation did not show any significant difference before and after the treatment. There were not any significant difference in the means of HDL, LDL, triglyceride, inhibition of platelet aggregation, the means of systolic and diastolic blood pressure and the mean arterial blood pressure (MAP), between the two groups, but there was a significant difference in the means of total cholesterol (P=0.038) and hypertension alone (P=0.043). CONCLUSION The administration of 800mg/day of Garlet during the third trimester of pregnancy was effective in reducing the occurrence of hypertension alone, but it was no effective in preventing of preeclampsia.

Abstract
OBJECTIVE To determine whether vitamin E is effective in the treatment of primary dysmenorrhoea. DESIGN A randomised placebo-controlled trial. PARTICIPANTS One hundred girls, aged 16-18 years old who suffered from primary dysmenorrhoea, among 1,000 students attending a public high school in Region 5 in the Greater Tehran Municipality. METHODS Fifty girls were given 500 units of vitamin E (five tablets) per day, and 50 were given five placebo tablets per day. The treatment began two days before the beginning of menstruation and continued through the first three days of bleeding. The severity of pain before and after the treatment was studied. Treatment in both groups was carried out in two consecutive menstrual periods. RESULTS The severity of pain in the two groups was reduced after treatment, but the reduction was greater in the group treated with vitamin E. These differences were maintained in the second month of therapy. CONCLUSION Both placebo and vitamin E are effective in relieving symptoms due to primary dysmenorrhoea, but the effects of vitamin E are more marked.
