Abstract

This is a mortality study in internal medicine wards of Amir-Alam Hospital, since the beginning of 1374 to end of 1376. Here, we reviewed, prevalence of disease lead to death, the ward and invasive interventions and duration of admission of patients before death. In this study, records of 85 patients were reviewed. 68.2% of patients were men and 31.8% women. Mean of age was 61.6% with minimum of 18 and maximum 95 years. The most prevalent diseases leading to death were cardio vascular (41.2%), cancer 29.4%, GI tract diseases (10.6%), pulmonary diseases (8.3%), CNS (7.1%), hemathologic (4.7%), DM (3.5%). Mean duration of stay in hospital before death was 6.6 days (max 30-min 1). This figure in different wards were: ward 1 (7 days), ward 2 (11 days), ward 3 (5.9 days) ICU (5 days) and CCU (4.7 days). 90.5% of patients died due to their diagnosed illnesses. Invasive tests and intervations were performed in 40% of them. As a whole 35 patient were died in CCU. This research and others like it showes the failures of our patient management system and can guide us in approaching to better medical care.

Abstract

Background: There is a growing interest in understanding the biological effects of time-tested folk medicinal plants including the green leafy vegetables, which supply minerals and vitamins to the diet. Trigonella foenum-graecum L (fenugreek) is a dietary vegetable and there are reports concerning its antinociceptive effects in Iranian traditional medicine. Its seeds are also known for their carminative, tonic, antidiabetic, antineoplastic and restorative properties. These reports and the hypoglycemic effect of fenugreek leaf extract encouraged us to assay fenugreek aqueous extract for cytotoxicity on NIH3T3 mouse fibroblast cells.

Methods: The NIH3T3cell line was purchased from National Research Center for Genetic Engineering and Biotechnology of Iran. The cells were plated in 24-well microtiter plates with DMEM+F12 medium containing 10% fetal calf serum supplemented with 445 mg/L L-glutamine and maintained at 37oC with 5% CO2/95% air. Following a 24-hr incubation period, various concentrations (0.01-20 mg) of the extract to the culture wells. Cell viability was assessed using trypan blue and MTT assays after five days of incubation.

Results: The results show that the IC50 of the fenugreek extract as calculated from the trypan blue and MTT assays were 1.25 and 2.5 mg/mL, respectively.

Conclusions: Our findings, therefore, suggest that the aqueous extract of fenugreek is classified as nontoxic. This observed cytotoxicity is not specific and could be due to membrane disturbances.

The aim of this study was to evaluate the selective screening method for gestational diabetes mellitus (GDM) based on: 1- recommendation of the fourth workshop- conference on GDM 2- evaluation of risk factors
Methods: A case- control study was performed on 370 pregnancies inflicted by GDM in Hazrat Zaynab Hospital, Shahed University. The maternal and perinatal outcomes and prevalence of risk factors based on recommendation of the fourth workshop- conference on GDM in these women with GDM were compared with the same data and risk factors of randomly selected 600 pregnant women at the same time and in the same hospital, they all underwent universal testing for GDM, and their OGTT were normal.
Results: The prevalence of all risk factors was significantly higher in the group with GDM, but 45 of these women (12%) had no risk factors. 107 women (29%) with GDM were at low risk and would remain undiagnosed if selective screening method was used. The main neonatal complications in the low- risk group did not differ from the complications in other women with GDM.
Conclusions: The universal screening of all pregnant women seems to justified whereas the recommendations for not screening low- risk group are doubtful and require further examination.

Abstract

Background: Learning and memory are the complicated agents of central nervous system that various regions of brain can be involved in these phenomena, especially regions like hippocamp. Various agents like nitric oxide and morphine can influence learning and memory. About the effects of morphine with other components there was not clear reports so in this study the effect of co-administration of L-Arginine (precursor of nitric oxide) and morphine in hippocampal CA3 area on spatial learning and memory in male rats was investigated.
Methods: Male rats were deeply anaesthetized with ketamine and xylazine and cannula were implanted bilaterally in CA3 of hippocampus by using streotaxic technique, Then male rats were used in seven groups that received saline, L-Arginine (0/3M), L-Arginine (3μg/rat), L-NAME (0/3M), morphine (10mg/rat), L-Arginine (3μg/rat) with morphine or L-NAME with morphine for five days that they were trained in morris water maze to evaluate spatial learning and memory. There was a control group too.
Results: Our results showed that L-Arginine (3μg/rat) improved spatial learning and memory. L-NAME (inhibitor of nitric oxide) decreased spatial learning and memory in male rats. Injection of morphine also decreased spatial learning and memory in male rats. Co-administeration of L-NAME and morphine decreased learning more than morphine individually in male rats.
Conclusion: We concluded that precursor of nitric oxide improved learning and memory in male rats and inhibitor of it and morphine impaired this phenomena and coadministration of inhibitor of nitric oxide and morphine also impaired learning in rats.

Abstract

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Background: The techniques used in assisted reproductive technologies have progressed considerably, but many embryos do not implant after transfer upon the use of these techniques. One of the causes of infertility is repeated implantation failure due to decreased endometrial receptivity. Furthermore, in clinical conditions such as endometriosis and myoma, implantation decreases after embryo transfer. In this case-control study the expression patterns of HOXA-10 and BTEB1 mRNAs were evaluated at the time of implantation in patients with myoma and endometriosis.
Methods : In this study performed in Hamadan University of Medical Sciences during 1389, the cases included 16 patients with endometriosis and myoma (8 in each group) and the control group consisted of 8 fertile women. Endometrial sampling was performed at mid-secretory phase. Later, the expression patterns of HOXA-10 and BTEB1 mRNAs were evaluated using a semi-quantitative RT-PCR method.
Results : The optimal PCR cycles determined were 30, 32 and 26 for HOXA10, BTEB1 and β-actin, respectively. Endometrial HOXA-10 and BTEB1 mRNA expression levels (normalized to ß-actin expression) at the time of implantation were significantly decreased in the endometrium of infertile patients with endometriosis compared with that of healthy fertile controls (P<0.05). A similar pattern was seen in patients with myomas for both HOXA10 and BTEB1 genes, (P<0.05).
Conclusion: It seems that lower expression of HOXA-10 and BTEB1 mRNAs in the implantation window of endometrium that increase normally, could account for some aspects of infertility in patients with endometriosis and myoma.

Abstract

Background: Ascorbic acid (AA) is not synthesized in the brain but it is actively transported through blood-brain barrier by SVCT2 cotransporter and it is stored in high concentrations with heterogeneous distribution in areas such as nucleus accumbens shell (AcbSh) in the mammalian brain. Previous studies have shown that Ascorbic acid injection into AcbSh decreases feeding therefore, in the present study we evaluated the effects of oral Ascorbic acid pretreatment on changes in feeding upon its injection in AcbSh in adult male rats.

Methods: Sixty-three adult male rats (220-280 g) were divided into five treatment and five pretreatment groups. The treatment groups included the control (intact) group, sham-operated Ascorbic acid group that received normal saline as vehicle, and three other groups that received different doses of ascorbic acid (10, 50 and 250 µg/rat) by injection into AcbSh for four days. The pretreatment groups received Ascorbic acid (100 mg/kg) for 15 days via gastric gavage before receiving the aforementioned doses in treatment groups into intra nucleus AcbSh. Feeding measurement was repeated every 12 hours by automatic metabolic cage.

Results: The results indicated that all injected doses of Ascorbic acid (10, 50 and 250 µg/rat) into nucleus accumbens shell decrease food intake (P<0.05) in rats and oral Ascorbic acid pretreatment had no effects in this regard.

Conclusion: Our findings show that ascorbic acid is an effective factor in feeding regulation. Oral pretreatment seems to have no influence on the central effects of ascorbic acid in the nucleus accumbens shell.

Abstract

Background: Brucellosis is one of the most common infectious diseases in Iran with very different clinical manifestations.

Methods: In this retrospective descriptive study, all patients with brucellosis, who were admitted in Farshchian Hospital in Hamadan, Iran in 2005 to 2010, were enrolled in the study. The data were collected from the patients' medical records and were entered in forms for analysis.

Results: A total of 230 patients with brucellosis, including 130 (56.5%) male and 100 (43.5%) female patients with a mean age of 40.84±20.29 years, who mostly (72.2%) lived in rural areas were enrolled in the study. Outbreaks were most common in spring and summer and the main route of transmission was consumption of contaminated dairy products (60.3%). The most common symptoms were fever (77.4%), arthralgia (70%), sweating (47%), malaise and fatigue (46.5%). Arthritis and epididymo- orchitis were seen in 121 (52.9%) and 48 (8.20%) patients, respectively. CBC analysis showed leukocytosis in 20.8% of the participants. ESR rise was noted in 59.5% of the patients and 52.9% had positive CRP.

Conclusion: Given to various clinical presentations, brucellosis should be considered in the differential diagnosis of individuals with chronic fever with or without other organ abnormalities.

Abstract

Background: The purpose of this study was to determine the prevalence and associated factors for postoperative pulmonary complications (PPCs) and extubation failure in patients having undergone intracranial surgery.

Methods: In this retrospective study done in Firozgar Hospital during 2008-2010, we followed up 254 patients through a clinical questionnaire and observation of the clinical course of participants in pre- and post-operative periods.

Results: Overall, 40 (15.74%) patients had postoperative pulmonary complications. The most common PPC was pneumonia, which was seen in 24 patients (60% of complications). The average duration of ventilation in patients with PPC was significantly higher (16.8.±10 vs. 5.09±4.5 days P=0.001) than patients without the complication. The mean Glasgow coma scale (GCS) after surgery in patients with PPC was significantly lower (11.±4 vs. 13.2±3 P=0.001) than the rest of the patients. Moreover, the mean age of patients with PPC was significantly higher (64.02±14 vs. 41.6.±17 years P=0.001). Average duration of stay in ICU in patients with PPC was also higher (24.±27 vs. 8.7±0.5 P=0.001).

Conclusion: GCS before surgery and failed extubation independently of other variables were significantly associated with pulmonary complications independent of other variables.

Abstract

Background: Gonadotropins are commonly used for superovulation in human and animals to retrieve more oocyte and increase chance of pregnancy. Ovarian stimulation in assisted reproduction technology produces lower implantation rates per embryo transferred than natural and ovum donation cycles, suggesting suboptimal endometrial development due to the hormones used to recruit more oocytes. Due to the frequent use of gonadotropins in the treatment of infertility in successive periods, the aim of this study was to determine the endometrial changes in response to repeated ovarian stimulation. Methods: This experimental interventional study has done in research center of Hamadan university of medical sciences in 2012. NMRI female mice six weeks old were used in this study and divided into 7 groups (5 each). The mice in group 1, 2, 3 and 4 received 1, 2, 3 and 4 times pregnant mare serum gonadotropin (PMSG) and 48 hours later 7.5 IU human chorionic gonadotrophin (hCG) respectively. For each group were considered a control group which received on time gonadortropin injection. The mouses were killed 13-16 hours after hCG injection and middle part of uterine horn cut for histological study using Hematoxylin and Eosin staining. The parameters that studied were surface epithelium of endometrium, glandular epithelium, and endometrial height and axis of uterine gland. Results: Our results showed that there are no significant differences in glandular epithelium, axis of glands and height of endometrium in experimental groups (P>0.05). The height of surface epithelium showed significant increases after ovarian stimulation in experiment group (P≤0.03). Our results showed that there are no significant differences in glandular epithelium, axis of glands, height of endometrium and height of surface epithelium between control groups and also it's experimental group (P>0.05). Conclusion: Changes in the height of surface epithelium could be one of the reasons for decrease implantation rates with repeated ovarian stimulation.

Abstract

Background: Thyroid carcinoma is the most common endocrine malignancy. Medullary thyroid carcinoma (MTC) approximately accounts for 5-10% of all thyroid carcinoma. Nowadays, it is obviously, the mutations in REarranged during transfection (RET) proto-oncogene, especially, mutations in exons 10, 11 and 16 are associated with MTC pathogenesis and occurrence. Thus, early diagnosis of MTC by mutation detection in RET proto-oncogene allows to identify patients who do not have any developed symptoms. The aim of this study was to screening of germline mutations in RET proto-oncogene exons 17 and 18 in MTC patients and their first degree relatives in Iranian population.

Methods: In this cross-sectional study, three hundred eleven participates (190 patients, 121 their relatives) were referred to endocrine research center, Shahid Beheshti University of Medical Science during September 2013 until September 2015. The inclusion criteria were pathological and clinical diagnosis. After whole blood sampling, genomic DNA was extracted from peripheral blood leucocytes using the standard Salting Out/Proteinase K method. Nucleotide change detection in exons 17 and 18 was performed using PCR and direct DNA sequencing methods.

Results: In this study, twenty missense mutations [CGC>TGC, c.2944C>T, p.Arg982Cys (rs17158558)] which included 16 heterozygote and 4 homozygote mutations were found in codon 982 (exon 18). In the present study, 154 G>A (rs2742236) and 4 C>T (rs370072408) nucleotide changes were detected in exons 18 and intron 17 respectively. There was no mutation in exon 17.

Conclusion: It seems that because of arginine to cysteine substitutions in RET tyrosine kinase protein structure and its polyphen score (0.955) and SIFT score (0.01) the mutation in codon 982 (exon 18) could be have pathogenic effects. On the other hands, the mentioned mutation frequency was 6.4% among MTC patients, so this mutation of exon 18 could be checked in genetic screening tests of RET proto-oncogene. Although this needs more study.

Abstract

Background: According to the direct connection between congenital hypothyroidism and iodine deficiency in pregnant women, also relatively high incidence of congenital hypothyroidism in some areas of Kerman province, especially Raver district located in North of Kerman province, this study was performed to determine and compare the urinary iodine concentration (UIC) in pregnant women referring to health centers.
Methods: This cross-sectional study was done during March 2014 and May 2015. Inclusion and exclusion criteria to be considered and UIC were measured by spectrophotometry in 384 and 374 pregnant women in Ravar and Kerman cities, Iran. Sampling method for this study was all of pregnant women in Ravar and random stratified sampling in Kerman. data were collected using a structured questionnaire. All statistical analyses were performed using SPSS Software, version 20.0 (IBM SPSS, Armonk, NY, USA). Chi-square test, Pearson's correlation coefficient and Logistic regression were used for associations and differences.
Results: The mean UIC was 200.21 µg/L in pregnant women of Ravar and 238.79 µg/L in pregnant women of Kerman. 22.7% of pregnant women were with low concentrations of iodine, 57.8% within the normal range and 19.5 percent were with high iodine concentrations in Ravar. While 5.3 percent of pregnant women were with low concentrations of iodine, 54.5% were within the normal range and 40.1% were with high UIC in Kerman. There were no significant differences between demographic variables and UIC in the two regions (P> 05/0). Multivariate regression models showed significant connections between the residence and UIC pregnant women (P< 0.001).
Conclusion: The results of this study showed that UIC in pregnant women of Ravar was significantly lower than Kerman and the place of living can be considered as a predictor of UIC in pregnant women.
