Prenatal multivitamin supplementation increases birth weight

Background: The aim of this study is to examine whether there is any positive impact of prenatal iron and vitamin supplementation on birth weight, and if this practice could be a cause of macrosomia.Methods: A total of 1,838 term pregnant women were included in this study and were divided into four groups: iron group (women having only iron supplementation), vitamin (women using only multivitamins), vitamin+iron (women using both iron and multivitamin preparations), and control group (women having neither iron nor vitamin supplements). Statistical analysis was performed to compare age, gravida, parity, hemoglobin, BMI and birth weight. Groups were compared in terms of macrosomia and correlation analysis carried out between demographics and birth weight.Results: The birth weight was significantly higher in the vitamin group and the vitamin+iron group than in the iron group and the control group. Vitamin supplementation increased the risk of macrosomia 3.9 times, while vitamin+iron usage increased the risk 4.8 times.Conclusions: Uncontrolled use of multivitamins and/or iron supplements may increase tendency for fetal macrosomia. The use of multivitamins and/or iron supplements by pregnant women must take into account maternal age, maternal diet and maternal BMI. Our findings support a reduction in the unnecessary use of vitamin and iron supplements in pregnancy, and a reversal of the trend to start vitamin and iron supplementation without any control. The increasing prevalence of obesity and excessive weight in pregnant women should be a warning against the uncontrolled usage of vitamins and iron during pregnancy

Effects of curcumin on ovarian ischemia-reperfusion injury in a rat model.

Ischemia-reperfusion injury is a significant problem following reperfusion treatment for ovarian torsion. It is generally caused by reactive oxygen species-induced damage. Antioxidant agents, such as curcumin, may protect ovaries from this adverse effect. The aim of the present randomized, controlled study was to evaluate the short-term protective effect of curcumin on a rat model of ovarian ischemia-reperfusion injury. A total of 30 female Wistar albino rats, weighing 160-230 g, were divided into 2 groups depending upon the time of unilateral, left ovary ischemia/reperfusion (group 1, 2 h ischemia/2 h reperfusion and group 2, 4 h ischemia/4 h reperfusion). These groups were subdivided into 3 subgroups (sham, control and curcumin). The sham subgroups were not subjected to ischemia/reperfusion. Control and curcumin subgroups were performed under ischemia for 2 h plus 2 h reperfusion or 4 h ischemia plus 4 h reperfusion. Curcumin, 200 mg/kg, was intraperitoneally administered simultaneously with reperfusion to the curcumin subgroups. Serum nitric oxide (NO), NO synthase (NOS), xanthine oxidase (XO), total antioxidant status (TAS), total oxidant status (TOS) and histological scores were measured and compared between subgroups. For group 1, no significant differences were observed between NO, NOS, XO, TAS or TOS. The left ovary histological grade was significantly higher in the control and curcumin subgroups compared with the sham subgroup (P=0.036). For group 2, TOS was significantly higher in the control group compared with the sham and curcumin groups (P=0.023). However, TAS was also significantly higher in the control subgroup compared with the other 2 subgroups (P=0.005). Left ovary histological grade was significantly higher in the control and curcumin subgroups compared with the sham subgroup (P=0.038). No significant differences were observed between NO, NOS or XO between the group 2 subgroups. The results showed that curcumin exerted no major significant protective effect on ischemia-reperfusion injury in the rat ovary

Is There a Relationship Between Pelvic Organ Prolapse and Tissue Fibrillin-1 Levels?

Purpose: Pelvic organ prolapse is a multifactorial disorder in which extracellular matrix defects are implicated. Fibrillin-1 level is reduced in stress urinary incontinence. In Marfan syndrome, which is associated with mutations in Fibrillin-1, pelvic floor disorders are commonly observed. We hypothesize that Fibrillin-1 gene expression is altered in pelvic organ prolapse. Methods: Thirty women undergoing colporrhaphy or hysterectomy because of cystocele, rectocele, cystorectocele, or uterine prolapse were assigned to a pelvic prolapse study group, and thirty women undergone hysterectomy for nonpelvic prolapse conditions were assigned to a control group. Real-time polymerase chain reaction was conducted on vaginal tissue samples to measure the expression of Fibrillin-1. Expression levels were compared between study and control groups by Mann-Whitney U test with Bonferroni revision. Results: Fibrillin-1 gene expression was not significantly lower in the study group than in the control group. Similarly, no significant correlation between Fibrillin-1 levels and grade of pelvic prolapse was found. Age over 40 years (P=0.018) and menopause (P=0.027) were both associated with reduced Fibrillin-1 levels in the pelvic prolapse group, whereas the delivery of babies weighing over 3,500 g at birth was associated with increased Fibrillin-1 expression (P=0.006). Conclusions: The results did not indicate a significant reduction in Fibrillin-1 gene expression in pelvic prolapse disorders; however, reduced Fibrillin-1 may contribute to increased pelvic organ prolapse risk with age and menopause. Increased Fibrillin-1 gene expression may be a compensatory mechanism in cases of delivery of babies with high birth weight. Further studies are needed for a better understanding of these observations

Gene Expression Profiles of Tumor Necrosis Factor-alpha and Endothelin-1 in Obstructive Sleep Apnea

Background/Aims: The aim of this study was to observe the relationship between the gene expression profiles of tumor necrosis factor (TNF)-alpha and endothelin (EDN)-1 and obstructive sleep apnea (OSA). Methods: A prospective, cross-sectional study performed at a tertiary-care academic center; 108 patients with snoring and day-time sleeplessness were included in this study carried out in the Otolaryngology Department. All patients were evaluated with 1-night polysomnography (PSG). There were 63 patients with OSA and 45 patients without OSA. In the OSA group, the median apnea hypopnea index (AHI) was 29.1; in the non-OSA group, the median AHI was 2.1. Blood samples were obtained from all 108 patients for the genetic analysis of the expression of TNF-alpha and EDN-1. PSG findings and gene expression levels were evaluated in both groups. Results: The median (range) age was 46 (20-81) years, BMI 24.9 (15-49), EDN-1 gene expression 0.45 (0.02-67.88) pg/mu L, and TNF-alpha gene expression 1.71 (0.08-59.52) pg/mu L. We found that EDN-1 and TNF-alpha gene expression levels were significantly higher in the OSA group than in the control group (p = 0.009 vs. p < 0.001). Conclusion: EDN-1 and TNF-alpha gene expression levels were associated with the occurrence of OSA. (C) 2018 S. Karger AG, Base

Galectin-3: A biochemical marker to detect paroxysmal atrial fibrillation?

Purpose: Atrial fibrillation (AF) is the most common form of arrhythmia. AF leads to electrical remodelling and fibrosis of the atria; however, the mechanism(s) remain poorly understood. Galectin-3 is a potential mediator of cardiac fibrosis. The present study aimed to examine the relationship between serum galectin-3 levels and paroxysmal AF. Methods: Forty-six patients with paroxysmal AF and preserved left ventricular systolic function, and 38 age- and gender-matched control subjects, were involved in the study. Serum galectin-3 levels were analyzed with an enzyme-linked immunosorbent assay (ELISA). Results: Serum galectin-3 levels (median 1.38 ng/mL; 1.21 ng/mL-1.87 ng/mL; p< 0.001) were significantly elevated in patients with paroxysmal AF compared with the control. Left atrial diameter was significantly higher in patients with paroxysmal AF (41.2±3.0 mm vs. 39.6±3.3 mm). Left atrial diameter was found to be significantly correlated with serum galectin-3 levels in patients with paroxysmal AF (r= 0.378, p= 0.001). Conclusion: Serum galectin-3 levels are significantly elevated and significantly correlated with left atrial diameter in patients with paroxysmal AF

The effects of hypnotherapy during transrectal ultrasound-guided prostate needle biopsy for pain and anxiety

Several studies evaluating the tolerance of transrectal ultrasound (TRUS)-guided needle biopsies showed that moderate-to-severe pain was associated with the procedure. Additionally, prebiopsy anxiety or rebiopsy as a result of a prior biopsy procedure is mentioned as factors predisposing to higher pain intensity. Thus, in this study, we investigated the effects of hypnotherapy during transrectal ultrasound-guided prostate needle biopsy for pain and anxiety
