Background: Ventilator Associated Pneumonia (VAP) is one of the serious complications of ventilator support occurring in ICUs. The aim of this study was to determine the susceptibility pattern of Acinetobacter baumannii (A. baumannii) isolated from patients with VAP by two methods: disk diffusion and E. test.
Methods: This descriptive-cross sectional study was conducted in the four ICUs of Rasoul-e-Akram Hospital in Tehran, from October 2016 to November 2017. A total of 58 endobronchial aspirates from intubated patients who had been clinically diagnosed to have VAP by A. baumannii were studied. The in vitro susceptibility was determined by disk-diffusion and broth microdilution MIC methods. The results were used in chi2 assay to express a meaningful relationship. P<0.05 was considered statistically significant.
Results: With the E. test method high percentage of isolates were resistant to levofloxacin (100%), carbapenems (meropenem: 93.10%, imipenem 70.69%), piperacillin-tazobactam (50%) and aminoglycosides (gentamicin 41.38%). The most sensitive antibiotic was colistin.
Conclusion: Antimicrobial resistance to A. baumannii in ICUs is increasing, and the findings of the study have shown that colistin is the only drug with relative efficacy.

Insulin is essential for type 1 and advanced type 2 diabetes to maintain blood glucose levels and increase the patient’s longevity. Frequent subcutaneous insulin injections are usually associated with pain, local tissue necrosis, infection and nerve damage. Recently, a number of new delivery methods such as oral insulin delivery have been developed to overcome these limitations and increase patient’s satisfaction. Oral delivery of insulin and other therapeutic peptides/ proteins are associated with poor intestinal absorption and enzymatic degradation in the gastrointestinal tract. However, Cell Penetrating (CPPs) and transytosing peptides have exhibited promising potential as carriers that conjugated to insulin and capable to across the intestinal epithelium. Numerous studies have shown that after conjugation of insulin with CPPs and transytosis peptides these biomolecules can retain their biological activity and also are stable and resistant to proteolytic degradation. In this review, following the introduction of different types of CPPs and also transytosis peptides, we have focused on the studies that they use these peptides as a powerful technology for oral insulin delivery. Based on the results of these studies, oral insulin will not only be a good candidate for painful injections in diabetic patients, but also mimics the physiology of endogenous insulin secreted by pancreas.

Background: Vitamin D deficiency is a common disorder in elderly, previously suggested to be associated with cognitive impairment. This study was aimed to determine the association between 25(OH) vitamin D and cognitive impairment in the elderly.
Methods: In this case-control study, 35 individuals who met criteria of cognitive impairment were examined against 35 individuals who did not have cognitive impairment. Serum 25(OH) vitamin D levels were measured in both fasting groups by ELISA kits. Data were collected using a checklist containing demographic data and serum vitamin D levels in two groups and analyzed using SPSS 16 software.
Results: The mean age of the control group was 67.91±4.78 years and of the case group was 68.91±3.63 years (p=0.328). The mean serum level of 25(OH) vitamin D in the control and case groups was 37.28 ng/ml and 23.06 ng/ml, respectively. The observed difference was statistically significant (p=0.003). 20 (57.1%) of control group and 10 (28.6%) of case group had sufficientlevels of vitamin D (p=0.01). The odds ratio of cognitive impairment in the case group was 3.3 times higher than control group, which was also statistically significant (p=0.001).
Conclusion: Elderly people with cognitive impairment have lower levels of vitamin D than healthy ones with same age, which may be related to their cognitive impairment. However, confirmation of the results of this study requires further studies with a larger sample sizes.

Background: Regarding the physiological and immunological changes of the human body following acute exhaustive activity and the evidence in traditional medicine of the effects of barberry on the strengthening of the immune system, the aim of this study was evaluation of the effect short-term barberry juice supplementation on the response of immunoglobulin A, G, M and cortisol in active girls following exhaustive exercise activity.
Methods: In this clinical trial study, 20 healthy young girls (23.92±1.28 years, weight 55.69±5.71 kg) were randomly divided into two experimental group (consumption of 250 ml barberry juice and exhausting activity) and control group (consumption of 250 ml placebo and exhausting activity). After the two-week supplementation, both groups performed exercise activity until they were of exhaustion on the treadmill. In this research, the nutritional value of barberry juice was extracted and the subjects' nutrition was analyzed. Blood samples were measured to measure the humoral immune variables in similar conditions in three stages of pre-test, after two weeks of supplementation and after the exhaustive test and using Independent T-test, ANOVA with repeated measure and Bonferron's post hoc test were analyzed at p≤0.05.
Results: The results showed that in the experimental group, the levels of immunoglobulin A (p=0.026), G (p=0.013) and M (p=0.017) after acute exhaustive activity were significantly higher than the control group, whereas in the experimental group cortisol values (p=0.018) were significantly lower than the control group.
Conclusion: It seems that consumption of barberry juice for two weeks with increased immune function reduces the effects of acute exhausting activity on the immune system in active girls.

Background: Malaria is one of the most important tropical diseases that is prevalent in some of regions of Iran and the world. The malaria agent is resistant to different chemical drugs which have several side effects. So, the use of various medicinal plants, especially different species of Artemisia herb which have artemisinin as its active ingredient, is significantly important. Therefore, the aim of this study was to evaluate the effect of alcoholic extract of Artemisia fragrance herb as compared with chloroquine in laboratory albino mice exposed to Plasmodium berghei (P.berghei).
Methods: In this experimental study, twenty-five mice were divided into five groups (n=25 mice/group) placed in separate cages: four groups were infected with P.berghei. Two groups were treated with different concentrations (25 and 75 mg/kg) of alcoholic extract of Artemisia fragrance and one group was treated with chloroquine current drug. The fourth group was a placebo group without receiving any drugs. The data were analysed using SPSS software and paired and student T-test.
Results: In groups treated with 25 and 75 mg of the extract, parasitemia decreased significantly on days 5 and 8 compared to placebo groups (p<0.001). Mean while, the parasitemia rate decreased in the 75 mg group than in the group receiving 25 mg on day 5 (p<0.005). The life span of the mice in the group treated with chloroquine and 75 mg of the extract had a statistically significant difference with other groups (p<0.05).
Conclusion: This study showed that alcoholic extract of Artemisia fragrance in 75 mg/kg mice weight concentration has a significant effect on P.berghei parasite.

Background: Unit of p65 is one of the subunits of NF-κB and its phosphorylation by stress oxidative causes activation of NF-κB. The aim of present study was to investigate the effects of adenosine injection after brain ischemia reperfusion injury on gene expression of NF-κB /p65 and Reactive Oxygen Species (ROS) in hippocampus tissue of male wistar rats.
Methods: 40 male wistar rats were randomly divided into four groups, healthy control (n=10), ischemia reperfusion (n=10), ischemia reperfusion + adenosine dose of 0.1 mg/kg (n=10) and ischemia reperfusion + adenosine dose of 0.4 mg/kg (n=10). The animals were subjected to ischemia by the ligation of common carotid arteries for 45 min. Intraperitoneal injection of adenosine was done after 24 h ischemia in rats. The gene expression of NF-κB /P65 and ROS activity were examined by Real time-PCR and Spectroflourimeter, respectively. One-way ANOVA and Bonferroni post hoc test were used to analysis the data. The significant level was set at p<0.05.
Results: The results showed that ischemia induced significant increase in gene expression of NF-κB /p65 and ROS activity compared to control group (p<0.05). Also, both dose of adenosine resulted in significant decrease in gene expression of NF-κB /p65 and ROS activity compared to ischemia group (p<0.05).
Conclusion: Brain ischemia reperfusion causes the stress oxidative. It appears that injection of adenosine is effective in reduction of stress oxidative and inflammation due to brain ischemia reperfusion.

Background: The transition from communicable to non-communicable diseases has occurred over many years in all countries of the world, even in developing countries. Diabetes and its ischemic heart complication are among the most important second groupe diseases. In recent years, discussions about the role of obesity and weight gain have risen again as a risk factor for both diseases. Our objective of this study was to determine the relationship between body mass index and prevalence of ischemic heart disease in type 2 diabetic patients in Iran.
Methods: This study was conducted in 2018 in 666 patients with type II diabetic patients registered in the Family physician system in Malard County. Data were gathered through medical records and then analyzed by SPSS software using Chi-square method.
Results: Of these, 177 were male and 489 were female. Our findings showed that 73 type 2 diabetic patients (10.96%) had ischemic heart disease (51 women and 22 men). In terms of body mass index, 2.7% were in the under-weight group, 21.9% in the normal weight group, 37% in the overweight group, 27.4 % in the grade1 obesity group, 8.2% in the grade 2 obesity group, and 2.7% were in the grade 3 obesity group.
Conclusion: According to our findings, although the prevalence of type 2 diabetes in overweight and grade1 obesity people is higher than normal or underweight individuals, the prevalence of ischemic heart complication in type2 diabetic patients is not consistent with this trend, and not only ischemic heart disease is not low in normal weight subjects, but also is slightly lower from grade 1 obesity and is higher than grade 2 and 3 obesities. Also, the distribution of ischemic heart disease in type 2 diabetic women and men is different among groups with different Body Mass Index and prevalence of ischemic heart disease in females more than males in normal weight group.

Background: This study was performed to determine the prevalence of spinal deviation such as forward head posture (FHP), exacerbated kyphosis, lumbar lordosis and scoliosis among 7 to 9-year-old students in the south of Tehran Done.
Methods: This cross-sectional study was performed on 2114 healthy students with an average age of 7.99 ± 0.81year, 1059 of which were females and 1055 were males. Individual profile, visual evaluation of the sagittalplane in relation to plumb line from lateral view, and scoliosis assessment with forward bending test (FBT) were performed. Data processing was done by21th version of SPSS. The relationship between the variables was examined by regression method.
Results: The prevalence of FHP was 68.4%, exacerbated lordosis 69.1%, exacerbated kyphosis 68.6%, and scoliosis 15.7%. There is a significant relationship between FHP with age and sex, as well as the correlation between KFIS and Body Mass Index (BMI), and also between intensified lordosis with gender and BMI, ultimately derived from scoliosis with BMI.Increased kyphosis, intensified lordosis, and scoliosis were common among girls, while FHP was common in boys. Children with a low BMI were susceptible to hyper lordosis, exacerbated kyphosis and scoliosis. There was also no significant relationship between vertebral column deviations and method of the school bagcarriage.
Conclusions: Regarding to the high prevalence of spinal deviations in this age group, a regular screening program to identify and treat malalignments of these children in schools is recommended. Because of significant outbreak of spinal deviations in children with low BMI, the exact attention of parents to body alignment and mass of children is essential.
