Elevated fibrinogen levels is related to the blood hyperviscosity, that causes low blood velocity. Non-contrast-enhanced transcranial Doppler (TCD) is used to evaluate blood flow from the cerebrovascular system. To know the relationship between fibrinogen levels and examination of TCD in acute ischemic stroke through evaluation. A cross sectional study was admitted from July 2012-Juny 2013. The researchers determined the differences between fibrinogen and TCD in the stroke group and control. The researchers examined the relationship between fibrinogen and TCD examination in the stroke group. The fibrinogenwas measured with Clauss method. The TCD was examined due to middle of the cerebral artery (MCA) and the Internal Carotid one Artery (ICA). The patients were diagnosed as ischemic stroke from head CT-scan. Statistical analyses employed the Independent T test, Anova test and Pearson correlation. The researchers had 24 patients and 24 controls that the Fibrinogen levels in stroke group is 549.16±104.84 mg/mL and in the control group is 385.64±16.80 mg/mL. The researchers examined MCA in the stroke as well as the control and found the mean velocity 43.12±21.03and 56.97±6.22 (p=0.05), the peak velocity 74.17±32.58 and 94.55±14.11 (p=0.05) end diastolic velocity 23.27±12.66 and 35.30±7.34 (p=0.00). In ICA, the stroke group and control and found the mean velocity 31.40±8.86 and 43.07±8.06 (p=0.00), thepeak velocity 54.99±11.50 and 75.04±16.04 (p=0.00) end diastolic velocity 18.23±7.67 and 25.64±5.24 (p=0.00). The correlation between fibrinogen and TCD in the stroke group was not significant on MCA and ICA, P>0.05. It can be concluded that the differences between fibrinogen levels and TCD in the stroke group and control are significant. But there is no correlation between the fibrinogen and TCD in the stroke group.

Abstract Background: Sex hormones may be associated with a higher incidence of ischemic stroke or stroke-related events. In observational studies, lower testosterone concentrations are associated with infirmity, vascular disease, and adverse cardiovascular risk factors. Currently, female sexual hormones are considered neuroprotective agents. The purpose of this study was to assess the role of sex hormones and the ratio of estradiol/testosterone (E/T) in patients with acute ischemic stroke (AIS).Methods: Between January 2011 and December 2016, 146 male patients with AIS and 152 age- and sex-matched control subjects were included in this study. Sex hormones, including estradiol, progesterone, and testosterone, were evaluated in the AIS patient and control groups. We analyzed the clinical and physiological levels of sex hormones and hormone ratios in these patients.Results: The E/T ratio was significantly elevated among patients in the stroke group compared to those in the control group (P = 0.001). Categorization of data into tertiles revealed that patients with the highest E/T ratio were more likely to have AIS [odds ratio (OR) 3.084; 95% Confidence interval (CI): 1.616-5.886; P < 0.001) compared with those in the first tertile. The E/T ratio was also an independent unfavorable outcome predictor with an adjusted OR of 1.167 (95% CI: 1.053-1.294; P = 0.003).Conclusions: These findings support the hypothesis that increased estradiol and reduced testosterone levels are associated with AIS in men.

<p><strong>OBJECTIVE:</strong> We aimed to measure abdominal pressure and placental levels of malondialdehyde in patients with preeclampsia and investigate the relationship between intraabdominal pressure and clinical features of preeclampsia.<br /><strong>STUDY DESIGN:</strong> Study was conducted at a tertiary referral clinic. Study group consisted of patients with preeclampsia and control group consisted of normotensive pregnant women. Both placental malondialdehyde and intraabdominal pressure levels were studied in all patients. Intraabdominal pressure was assessed indirectly via a Foley bladder catheter both antepartum and postpartum period. Statistical comparisons among groups were made using the Mann-Whitney U test, independent T test and Chi-square test. Statistical significance was set as p&lt;0.05.<br /><strong>RESULTS:</strong> Study and control group consisted of 35 pregnant patients. The mean patients’ age, gravidity, parity, weight and BMI were not different between study and control groups. In the study group, Caesarean, preterm delivery and abdominal hypertension rate were significantly higher whereas the mean neonatal birth weight was lower. The mean antepartum and postpartum intraabdominal pressure levels were significantly higher in study group. The mean intraabdominal pressure was highest in patients with oliguria (19.8±1.8 cmH2O). Abdominal hypertension was detected in 30 (86%) patients in study group and in 3 (9%) patients in control group. The mean placental malondialdehyde level was significantly higher in patients with intraabdominal hypertension.<br /><strong>CONCLUSION:</strong> Abdominal hypertension rate is very high in patients with preeclampsia. Abdominal hypertension may have an additional role in preeclampsia.</p>

Background: Stroke is the third commonest cause of death in developed countries and is responsible for the physical disability of a large population. The study was designed to see the association of serum folic acid with ischemic stroke. It was concluded that the low levels of folic acid are associated with ischemic stroke. Aim and objectives: To evaluate the association of serum folic acid level with ischemic stroke and to measure and compare the serum folic acid level among the cases and control subjects. Material and method: This study was a case-control study which was conducted in the Department of Neurology and Department of Biochemistry of BSMMU, Dhaka, between the period of 1st January 2010 and 31st December 2011 for duration of two years. A total number of 60 patients presented with ischemic stroke and 60 control person were enrolled in this study. All patients of both sexes, aged between 20 years and above presented with ischemic stroke, from 0 day to 1 month that was confirmed by CT scan of head/MRI of brain. Blood sample was collected from the cases and the controls and analyzed at the Dept. of Biochemistry, BSMMU for estimation of serum folic acid, serum homocysteine fasting blood sugar. Fasting lipid profile for cases only. Result: The mean ± SD of age of the cases was 58.42 ± 11.47 and among the cases 45 (75.0%) were male and 15 (25.0%) were female. Among the control male and female were 43 (71.7%) and 17 (28.3%) respectively. The mean (±SD) serum folate level of case and control group was 6.26(± 4.06) and 8.07(± 4.70) respectively. Statistically significant differences was observed between case and control group in term of Serum folate (p<0.05). This study showed serum folate level was deficient at the early period of ischemic stroke. Conclusion: Low serum folate concentration is significantly and independently associated with increased risk for ischemic stroke.

Postpartum depression (PPD) has adverse effects on the mother’s ability to work, her relationships, performance in other roles, and caregiving ability. The aim of this study was to compare levels of maternal functioning between mothers with depression symptoms and those without. The participants of this case-control study included 80 postpartum women (n = 40 with depressive symptoms and n = 40 with no depressive symptoms) referred to health centers in Tabriz, Iran, in 2018–2019. The case and control groups were matched for the number of deliveries (first or second deliveries) and the type of delivery (vaginal or cesarean section). A sociodemographic questionnaire, Edinburgh Postpartum Depression Scale (EPDS), and Barkin Index of Maternal Functioning (BIMF) were used for data collection. The relationship between maternal functioning and depression was assessed by conducting independent t-tests and Pearson correlation tests in bivariate analysis and applying the general linear model (GLM) in a multivariate analysis. There was no statistically significant difference between the two groups in terms of sociodemographic information. The mean (SD) total scores of maternal functioning in the case (depressed) and control (non-depressed) groups were 63.4 (12.2) and 93.3 (13.0), respectively. According to the independent t-test, this value in the control group was significantly higher than that of the case group (mean difference: −30.0; 95% confidence interval: −35.6 to −24.3; p < 0.001). In terms of the domains of the BIMF, based on the independent t-test, the mean score of all domains in the control group was significantly higher than that of the case group, except for the mother-child interaction dimension (p = 0.219). Based on the Pearson correlation test, there was significant negative correlation between the PPD score and total score of BIMF (r = −0.79, p < 0.001) and its domains (r = −0.81 to −0.54, p < 0.001). In addition, based on the GLM with adjusting the sociodemographic and obstetrics characteristics, the score of maternal functioning was significantly lower in the case group compared to the control group [β = −30.1; 95% CI: −36.8 to −23.4; p = 0.001]. The results of this study indicate that women with depressive symptoms have lower maternal functioning. Depressed women may find it difficult to perform their maternal duties and take care of themselves and other family members due to the burden of the depressive symptoms. Therefore, early diagnosis and treatment of postpartum depression can play an important role in improving daily maternal functioning.

Abstract Background Fibroblast growth factor-23 (FGF23) and α-klotho are associated with anemia in patients with chronic kidney disease. In this post hoc analysis of the ASTRIO study (UMIN000019176), we investigated the relationship between FGF23 and α-klotho during treatment with an iron-based phosphate binder, ferric citrate hydrate (FC), compared with non-iron-based phosphate binders in hemodialysis (HD) patients. We examined the effect of iron absorption by FC on the relationship between FGF23 and α-klotho. There have been few clinical studies evaluating these biomarkers simultaneously in HD patients. Methods The ASTRIO study was a 24-week, randomized, open-label, multicenter trial. HD patients taking non-iron-based phosphate binder(s) were randomized at a 1:1 ratio to continue other binder(s) (control group) or switch to FC (FC group). Serum phosphate (P) and hemoglobin (Hb) were maintained within 3.5–6.0 mg/dL and 10–12 g/dL, respectively. Plasma levels of intact FGF23 (i-FGF23), C-terminal FGF23 (c-FGF23), and α-klotho were measured, as were iron-related parameters. Association analyses of FGF23 and α-klotho were conducted. Results Patients were randomized to FC (n = 48) and control (n = 45) groups. Serum ferritin significantly increased from baseline to end-of-treatment (EOT) in the FC group, compared with the control group (adjusted mean difference [95% confidence interval]: 79.5 [44.7, 114.4] ng/mL; p <  0.001). The mean change from baseline to EOT in c-FGF23 was significantly different between the FC and control groups (mean ± standard deviation (SD): − 0.2 ± 0.8 loge pg/mL vs. 0.2 ± 0.8 loge pg/mL, respectively; p = 0.04). The mean change from baseline to EOT in i-FGF23 and α-klotho were not significantly different between the FC and control groups (mean ± SD: − 0.1 ± 0.8 loge pg/mL vs. 0.1 ± 0.9 loge pg/mL; p = 0.33, and 2.0 ± 91.5 pg/mL vs. − 8.9 ± 145.3; p = 0.58, respectively). However, both forms of FGF23 and α-klotho were not significantly associated with each other in both groups. Conclusions Iron absorbed via FC administration in HD patients did not influence the correlation relationship between plasma levels of FGF23 and α-klotho under the condition of serum P and Hb were maintained. Trial registration ASTRIO study (UMIN000019176, registered at UMIN Clinical Trials Registry on October 1, 2015).

Biosignal can provide information about body conditions, including physiological conditions of ischemic stroke. The regulation of blood in the brain is regulated through the mechanism of Cerebral Autoregulation (CA). Some parameters that can be used to determine this mechanism are Blood Flow Velocity (BFV) and Blood Pressure (BP). Stroke is also related to nervous system activity, which is represented through the Heart Rate Variability (HRV). This study aims to determine the relationship between those biosignals and their effects on the physiology of ischemic stroke sufferers. The subjects were divided into two groups (20 strokes and 20 controls). BFV data is obtained in the Middle Cerebral Artery (MCA), BP is obtained through the arteries of the upper arms, and 3 leads electrocardiogram is placed in the chest. The results showed that there was a relationship between BP and BFV in the control group (p-value < 0.05; r = -0.574). This correlation was not found in the stroke group. The relationship between BP and HRV was only found in the stroke group, which was associated with high sympathetic activity and lower parasympathetic activity (p-values < 0.05 and r > 0.4). It was based on SDRR, RMSSD, CVRR, LF, and SD1 parameters. In the control group, there was no relationship between HRV and BP. The relationship between BFV and HRV in the control group was not found statistically. Still, in the stroke group, this relationship was found in the LF and LF/HF Ratio parameters (p-value < 0.05; r > 0.4). Based on this research, parameters on HRV that can be used to determine the characteristics of stroke patients in all positions are MeanRR, VLF, and LF
