Aims/hypothesis: This study was designed to assess the effects of calcium and vitamin D supplementation on the metabolic status of pregnant women with gestational diabetes mellitus (GDM). Methods: This randomised placebo-controlled trial was performed at maternity clinics affiliated to Kashan University of Medical Sciences, Kashan, Iran. Participants were 56 women with GDM at 24-28 weeks' gestation (18 to 40 years of age). Subjects were randomly assigned to receive calcium plus vitamin D supplements or placebo. All study participants were blinded to group assignment. Individuals in the calcium-vitamin D group (n = 28) received 1,000 mg calcium per day and a 50,000 U vitamin D3 pearl twice during the study (at study baseline and on day 21 of the intervention), and those in the placebo group (n = 28) received two placebos at the mentioned times. Fasting blood samples were taken at study baseline and after 6 weeks of intervention. Results: The study was completed by 51 participants (calcium-vitamin D n = 25, placebo n = 26). However, as the analysis was based on an intention-to-treat approach, all 56 women with GDM (28 in each group) were included in the final analysis. After the administration of calcium plus vitamin D supplements, we observed a significant reduction in fasting plasma glucose (-0.89 ± 0.69 vs +0.26 ± 0.92 mmol/l, p < 0.001), serum insulin levels (-13.55 ± 35.25 vs +9.17 ± 38.50 pmol/l, p = 0.02) and HOMA-IR (-0.91 ± 1.18 vs +0.63 ± 2.01, p = 0.001) and a significant increase in QUICKI (+0.02 ± 0.03 vs -0.002 ± 0.02, p = 0.003) compared with placebo. In addition, a significant reduction in serum LDL-cholesterol (-0.23 ± 0.79 vs +0.26 ± 0.74 mmol/l, p = 0.02) and total cholesterol: HDL-cholesterol ratio (-0.49 ± 1.09 vs +0.18 ± 0.37, p = 0.003) and a significant elevation in HDL-cholesterol levels (+0.15 ± 0.25 vs -0.02 ± 0.24 mmol/l, p = 0.01) was seen after intervention in the calcium-vitamin D group compared with placebo. In addition, calcium plus vitamin D supplementation resulted in a significant increase in GSH (+51.14 ± 131.64 vs -47.27 ± 203.63 μmol/l, p = 0.03) and prevented a rise in MDA levels (+0.06 ± 0.66 vs +0.93 ± 2.00 μmol/l, p = 0.03) compared with placebo. Conclusions/interpretation: Calcium plus vitamin D supplementation in women with GDM had beneficial effects on their metabolic profile.

Diabetes mellitus-induced metabolic disturbances underlie the action of many systems including some higher functions of the brain such as learning and memory. Plenty of evidence supports the effects of probiotics on the function of many systems including the nervous system. Here we report the effect of probiotics treatment on the behavioral and electrophysiological aspects of learning and memory disorders. Diabetic rats were made through intraperitoneal injection of streptozocin. The control and diabetic rats were fed with either normal regimen (control rats recieving normal regimen (CO) and diabetics rats receiving normal regimen (DC), respectively) or normal regimen plus probiotic supplementation for 2. months (control rats receiving probiotic supplementation (CP) and diabetics rats recieving probiotic supplementation (DP), respectively). The animals were first introduced to spatial learning task in the Morris water maze. Then, in electrophysiological experiments, stimulating the Schaffer collaterals the basic and potentiated excitatory postsynaptic potential (EPSPs) were recorded in the CA1 area of the hippocampus. Finally, the serum levels of glucose, insulin, superoxide dismutase and 8-hydroxy-2'-deoxyguanosine (8-OHdG) were measured. We found that probiotics administration considerably improved the impaired spatial memory in the diabetic animals. The probiotics supplementation in the diabetic rats recovered the declined basic synaptic transmission and further restored the hippocampal long-term potentiation (LTP). While the probiotics administration enhanced the activation of superoxide dismutase and increased the insulin level of serum it decreased both the glucose level of serum and the 8-OHdG factor. From the present results we concluded that probiotics efficiently reverse deteriorated brain functions in the levels of cognitive performances and their proposed synaptic mechanisms in diabetes mellitus. These considerations imply on the necessity of an optimal function of the microbiome-gut-brain axis in the behavioral as well as electrophysiological aspects of brain action. © 2013 IBRO.


OBJECTIVE:: Preliminary data suggest that Foeniculum vulgare (fennel) can be an effective treatment for menopausal symptoms. This trial was designed to assess the efficacy of fennel in the management of menopausal symptoms in postmenopausal women. METHODS:: In this triple-blind, placebo-controlled trial, 90 postmenopausal women aged 45 to 60 years in Tehran were randomly assigned to treatment (n?=?45) or placebo (n?=?45) groups. The participants received 8 weeks of treatment with soft capsules containing 100?mg fennel or a placebo (2 per day for each group). The participants were followed for 2 weeks postintervention to assess the continuance of the effect of intervention. The Menopause Rating Scale (MRS) questionnaire was used to assess changes in menopausal symptoms at baseline and at 4, 8, and 10 weeks after onset of intervention. RESULTS:: The groups recorded similar mean scores on the MRS questionnaire before intervention. After intervention, the treatment group showed a significant decrease in the mean MRS score. The results of the Friedman test showed significant differences between the mean score at baseline and those at 4, 8, and 10 weeks after onset of intervention in the treatment group (P?

INTRODUCTION: Given that nurses are among professions with frequent ‎problems of fatigue, and given the nature of their profession that ‎provides little exposure to sunlight and the subsequent deficiency of vitamin D, the ‎present study examined the relation between fatigue and circulating vitamin D levels ‎in female nurses working in Shahid Beheshti Hospital, Kashan, Iran in 2013. ‎MATERIAL & METHODS: This cross-sectional study was conducted in 200 female nurses working in Shahid Beheshti Hospital. To measure fatigue, fatigue questionnaire containing 9 ‎questions eliciting the subject's feeling in scales of 1 to 7, getting a possible score of 9 to ‎‎63, and Visual Analogue Scale ‎in which nurses specified their fatigue in a band of zero to 10 were used. ‎The 25-hydroxyvitamin D, which is the most important vitamin D metabolite, also was determined. The data was analyzed by SPSS-16. The Pearson's correlation of coefficients, t-test, and multiple regression analysis were used in this study.‎RESULTS: The mean fatigue score of nurses was 38.76±12.66 in questionnaire and 5.73±2.12 in Visual Analog Scale. The 89 per cent of nurses suffered from vitamin D deficiency, ‎‎9.5 percent of them had normal level and 1.5 per cent had toxicity level of vitamin D.‎ There was a significant relationship between vitamin D level and fatigue scores (P<0.0001), and visual fatigue scores (P<0.0001). According to multivariate regression analysis, vitamin D level accounted for 13 per cent ‎of the fatigue based on data on questionnaire and‎ ‎18.6 per cent of ‎fatigue according to Visual Analog Scale. ‎CONCLUSION: High prevalence of fatigue among nurses could be attributed to vitamin D ‎deficiency.

During a postnatal critical period balance of excitation/inhibition in the developing brain is highly regulated by environmental signals. Compared to the visual cortex, rare document includes effects of sensory experience on the hippocampus, which is also bombarded by sensory signals. In this study, basic and tetanized field excitatory postsynaptic potentials (fEPSPs) were recorded in CA1 area of hippocampus of light-(LR) and dark-reared (DR) rats (at 2, 4 and 6 weeks of age). Also, we assessed age- and activity-dependent changes in the N-Methyl- d-aspartic acid (NMDA) and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors subunit compositions and, GABA producing enzymes. While the sensory deprivation increased amplitude of baseline fEPSPs, it decreased degree of potentiation of post-tetanus responses. Expression of GluA1 and GluA2 subunits of AMPA receptors was increased across age in DR rats. In contrast to LR rats, mRNA and protein expression of GluN1, GluN2A and GluN2B subunits of NMDA receptors was decreased in DR ones. Also, dark rearing diminished expression of GABA synthesis enzymes GAD65 and GAD67. These results indicate that, sensory experience adjusts synaptic plasticity and might also affect the balance of excitation/inhibition in the hippocampus. © 2016 IBRO.

Among Middle Eastern countries, at least 52 species of scorpions, especially dangerous types, have been reported in Iran. This is more than any other country in the region. In addition, in Iran the recorded scorpion stings from 2001 to 2009 were more than 42,500 per year, of which, approximately 19.5 deaths have been reported each year, mostly in spring and summer.About 10 species are responsible for the reported envenoming which belong to the Buthidae family apart from Hemiscorpius lepturus which is a Hemiscorpiidae. The Buthidae family includes: Androctonus crassicauda, Mesobuthus eupeus, Odontobuthus doriae, Hottentotta saulcyi, Hottentotta schach, Compsobuthus matthiesseni, Orthochirus scrobiculosus, Apistobuthus pterygocercus and Olivierus caucasicus. A. crassicauda and H. lepturus are usually cited as the most dangerous species among Iranian scorpions.This article focuses on the main Iranian scorpions and their geographical distribution, especially those which are medically important and considered to be the more dangerous to human, and also attempts to demonstrate an accurate magnitude of scorpion stings in Iran. © 2012 Elsevier Ltd.

For the first time, scientists have shown that probiotics -- beneficial live bacteria and yeasts taken as dietary supplements -- can improve cognitive function in humans. In a new clinical trial, scientists show that a daily dose of probiotic Lactobacillus and Bifidobacterium bacteria taken over a period of just 12 weeks is enough to yield a moderate but significant improvement in the score of elderly Alzheimer's patients on the Mini-Mental State Examination (MMSE) scale, a standard measure of cognitive impairment. Probiotics are known to give partial protection against certain infectious diarrheas, irritable bowel syndrome, inflammatory bowel disease, eczema, allergies, colds, tooth decay, and periodontal disease. But scientists have long hypothesized that probiotics might also boost cognition, as there is continuous two-way communication between the intestinal microflora, the gastrointestinal tract, and the brain through the nervous system, the immune system, and hormones (along the so-called "microbiota-gut-brain axis"). In mice, probiotics have indeed been shown to improve learning and memory, and reduce anxiety and depression- and OCD-like symptoms. But prior to the present study there was very limited evidence of any cognitive benefits in humans. Here, the researchers, from Kashan University of Medical Sciences, Kashan, and Islamic Azad University, Tehran, Iran, present results from a randomized, double-blind, controlled clinical trial on a total of 52 women and men with Alzheimer's between 60 and 95 years of age. Half of the patients daily received 200 ml milk enriched with four probiotic bacteria Lactobacillus acidophilus, L. casei, L. fermentum, and Bifidobacterium bifidum (approximately 400 billion bacteria per species), while the other half received untreated milk. At the beginning and the end of the 12-week experimental period, the scientists took blood samples for biochemical analyses and tested the cognitive function of the subjects with the MMSE questionnaire, which includes tasks like giving the current date, counting backwards from 100 by sevens, naming objects, repeating a phrase, and copying a picture. Over the course of the study, the average score on the MMSE questionnaire significantly increased (from 8.7 to 10.6, out of a maximum of 30) in the group receiving probiotics, but not in the control group (from 8.5 to 8.0). Even though this increase is moderate, and all patients remained severely cognitively impaired, these results are important because they are the first to show that probiotics can improve human cognition. Future research, on more patients and over longer time-scales, is necessary to test if the beneficial effects of probiotics become stronger after longer treatment. "In a previous study, we showed that probiotic treatment improves the impaired spatial learning and memory in diabetic rats, but this is the first time that probiotic supplementation has been shown to benefit cognition in cognitively impaired humans," says Professor Mahmoud Salami from Kashan University, the senior author of the study. Treatment with probiotics also resulted in lower levels of triglycerides, Very Low Density Lipoprotein (VLDL), high-sensitivity C-Reactive Protein (hs-CRP) in the blood of the Alzheimer patients, and likewise a reduction in two common measures (called "Homeostatic Model Assessment," HOMA-IR and HOMA-B) of insulin resistance and the activity of the insulin-producing cells in the pancreas. "These findings indicate that change in the metabolic adjustments might be a mechanism by which probiotics affect Alzheimer's and possibly other neurological disorders," says Salami. "We plan to look at these mechanisms in greater detail in our next study." Walter Lukiw, Professor of Neurology, Neuroscience and Ophthalmology and Bollinger Professor of Alzheimer's disease at Louisiana State University, who reviewed the study but was not involved in the research, said: "This early study is interesting and important because it provides evidence for gastrointestinal (GI) tract microbiome components playing a role in neurological function, and indicates that probiotics can in principle improve human cognition. This is in line with some of our recent studies which indicate that the GI tract microbiome in Alzheimer's is significantly altered in composition when compared to age-matched controls, and that both the GI tract and blood-brain barriersbecome significantly more leaky with aging, thus allowing GI tract microbial exudates (e.g. amyloids, lipopolysaccharides, endotoxins and small non-coding RNAs) to access Central Nervous System compartments."

This study was designed to assess the effects of Dietary Approaches to Stop Hypertension (DASH) eating plan on insulin resistance and serum hs-CRP in overweight and obese women with PCOS. This randomized controlled clinical trial was done on 48 women diagnosed with PCOS. Subjects were randomly assigned to consume either the control (n=24) or the DASH eating pattern (n=24) for 8 weeks. The DASH diet consisted of 52% carbohydrates, 18% proteins, and 30% total fats. It was designed to be rich in fruits, vegetables, whole grains, and low-fat dairy products and low in saturated fats, cholesterol, refined grains, and sweets. Sodium content of the DASH diet was designed to be less than 2 400 mg/day. The control diet was also designed to contain 52% carbohydrates, 18% protein, and 30% total fat. Fasting blood samples were taken at baseline and after 8 weeks intervention to measure insulin resistance and serum hs-CRP levels. Adherence to the DASH eating pattern, compared to the control diet, resulted in a significant reduction of serum insulin levels (-1.88 vs. 2.89 μIU/ml, p=0.03), HOMA-IR score (-0.45 vs. 0.80; p=0.01), and serum hs-CRP levels (-763.29 vs. 665.95 ng/ml, p=0.009). Additionally, a significant reduction in waist (-5.2 vs. -2.1 cm; p=0.003) and hip circumference (-5.9 vs. -1 cm; p<0.0001) was also seen in the DASH group compared with the control group. In conclusion, consumption of the DASH eating pattern for 8 weeks in overweight and obese women with PCOS resulted in the improvement of insulin resistance, serum hs-CRP levels, and abdominal fat accumulation.

The prevalence and incidence of end-stage renal disease (ESRD) are increasing in developed and developing countries, and this will place an enormous financial burden for health-care systems. The exact reasons of the rising prevalence of ESRD patients are unknown, but it can be attributed to an increase in the prevalence of diabetes mellitus and hypertension as the most common causes of ESRD. However, in contrast to the developed countries, the etiology of ESRD in the significant percent of patients with ESRD in Iran is unknown. In our country, the patients with chronic kidney diseases present themselves to the hospital only when they have severe symptoms of uremia, and, at this time, determining the primary cause of ESRD is often not possible. In addition, although the prevalence and incidence of ESRD are also significantly increasing in Iran in recent years, they are still lower compared with developed countries, which may also be due to poor referral resulting in the under diagnosis of ESRD. The aim of this review is to evaluate the epidemiologic aspects of ESRD in Iran, including demographic data, cause of ESRD, kind of renal replacement therapies implemented and their survival.

Postnatal development of the brain relies on genetic codes and sensory inputs. The hippocampus, a well-known area of the brain involved in learning and memory, receives indirect sensory signals through the entorhinal cortex. Stimulating perforant path (PP) excitatory postsynaptic potentials (EPSPs) were recorded in dentate gyrus (DG) and CA1 area of hippocampus of the light (LR) and dark (DR) reared rats at 2 (2W), 6 (6W) and 10 weeks (10W) of postnatal age. Then, the PP was tetanized to induce LTP in both sites of recording. We found a developmental decrease in the amplitude of baseline EPSPs in either DG or CA1 area in the LR rats; opposite was the case in their DR counterparts. Potentiation level in both the CA1 and DG was lower in the DR compared to LR animals. Also, the magnitude of LTP was site-dependent where the degree of LTP was considerably higher in the CA1 compared to the DG in either LR or DR rats. We concluded that: (a) visual signals are necessary for setting the basic activity of hippocampus to mature status, (b) visual deprivation negatively influences NMDA receptor-dependent hippocampal plasticity, (c) the CA1 and DG similarly respond to the sensory deprivation and (d) generally, LTP is weaker in the DG; irrelevant to degree of visual inputs to brain. © 2013 Elsevier B.V.
