Eating disorders (EDs) are widely known by abnormal eating behaviors associated with significant medical complications. Bulimia nervosa (BN) is an eating disorder characterized by uncontrolled episodes of overeating typically followed by some form of compensatory behaviors. We aimed to determine the relationships between socio-demographic characteristics, biochemical markers, and cytokine levels in BN candidates for laparoscopic sleeve gastrectomy (LSG).
A case-control study was designed among 76 BN participants of Iranian descent who were candidates for LSG based on defined criteria for Bulimia by Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). The healthy control subjects (n = 42) were selected at random from academic staff in the college. Moreover, levels of biochemical parameters and serum cytokines were measured in serum samples.
Routine consumption of caffeine (odds ratio [OR] = 3.1, 95% CI: 1.23-6.41, P = 0.013), tobacco (OR = 1.8, 95% CI: 0.67-3.57, P = 0.03), and alcohol (OR = 3.6, 95% CI: 0.84-7.18, P = 0.048), and depression history (OR = 2.8, 95% CI: 0.76- 5.79, P = 0.037) were substantially more common among patients with bulimia. Also, the serum levels of fasting blood sugar (P < 0.001), HbA1c (P = 0.04), cholesterol (P = 0.03), triglycerides (P = 0.01), blood urea nitrogen (P = 0.03), and pro-inflammatory cytokines including IL-1β, IL-6, and TNF-α were significantly higher in BN candidates for LSG (P ≤ 0.001).
Our findings reveal that lifestyle-related risk factors and a depression history were both related with a significantly increased risk of BN among the candidates for LSG. Furthermore, there is a relationship between clinical characteristics as well as levels of various biochemical and cytokines parameters in serum of BN patients.

Abstract Background: Medications nowadays have been commonly used items in the world and are sometimes available without prescription. This causes a range of effects on public health. This study evaluated the frequency and the involved factors of uncontrolled prescription drugs consumption. Methods: The present study is a cross-sectional study on 1,000 citizens of Tehran between 2016 and 2017. The various factors such as age, gender, and educational background have been carefully surveyed. The questionnaires were presented to interested people in printed form. For analyzing the data, descriptive statistics and analytical statistics were performed using SPSS software version 19. Results: 67% of participants use OTC drugs and 34% of them were between 20 and 30 years old. Although 12% of the OTC pills were used regularly as a pain killer, 95% of the people did not know anything about the side effects of the drugs. Moreover, 45% used the pill to relieve the common and acute pain and 34% of people lived in poverty and 12% suggested lack of adequate time as a reason to refuse visiting a doctor. Conclusion: Self-administered drug is one of the problems in the medical field. Headache is the main reason of self-medication. In the other hand, drug resistance is also rising among repeated drug users. According to the results, public education, the prohibition of the sale of some high-risk drugs and the reduction of drug doses are ways to prevent the development of such high-risk habits.

Numerous nosocomial infections including urinary tract infection (UTI) have been reported to be linked to Pseudomonas aeruginosa (P. aeruginosa). This bacterium is one of the most common pathogen colonized in the urinary tract. The main purpose of this study was to evaluated the presence of antibiotic resistance genes and also the most frequent genotype patterns of P. aeruginosa in the patients with UTI hospitalized in different wards of hospitals.
In this study, 70 strains of P. aeruginosa isolated of urine samples from the patients with UTI were assessed. The isolated strains were genotyped using Multiple-Locus Variable Number Tandem Repeat Analysis (MLVA) method. We have also analyzed the presence of TEM and SHV resistant genes in the isolates.
A total of 70 P. aeruginosa strains was isolated from the UTI patients. Based on MLVA method, 61 various genotypes of P. aeruginosa were identified which grouped into two main clusters and 4 sub-clusters. Moreover, approximately 80% and 70% of isolated strains carried the TEM and SHV resistance genes, respectively.
Our findings showed that the majority of patients hospitalized in different wards of hospitals have experienced the urinary tract infection caused by P. aeruginosa. According to the genotyping results, a high diversity of the P. aeruginosa population was observed in the patients with UTI. Our results can provide a better understanding of the P. aeruginosa genotype distribution and epidemiology of infection, which can be applied as basic data for future antibiotic therapies.

Overweight and obesity are among the most prevalent non-communicable diseases which are generally treated successfully by bariatric or sleeve surgery. There are evidences affirming that sleeve surgery can manipulate the pH of the stomach and interact with the metabolism of fatty acids, carbohydrates, and bile acid transfer, leading to the overgrowth of gut microbiota. Therefore, this study aims to review the changes in gut microbiota and hormones after bariatric surgery.

The emergence of resistant bacteria is being increasingly reported around the world, potentially threatening millions of lives. Amongst resistant bacteria, methicillin-resistant Staphylococcus aureus (MRSA) is the most challenging to treat. This is due to emergent MRSA strains and less effective traditional antibiotic therapies to Staphylococcal infections. The use of bacteriophages (phages) against MRSA is a new, potential alternate therapy. In this study, morphology, genetic and protein structure of lytic phages against MRSA have been analysed.
Isolation of livestock and sewage bacteriophages were performed using 0.4 μm membrane filters. Plaque assays were used to determine phage quantification by double layer agar method. Pure plaques were then amplified for further characterization. Sulfate-polyacrylamide gel electrophoresis and random amplification of polymorphic DNA were run for protein evaluation, and genotyping respectively. Transmission electron microscope was also used to detect the structure and taxonomic classification of phage visually.
Head and tail morphology of bacteriophages against MRSA were identified by transmission electron microscopy and assigned to the Siphoviridae family and the Caudovirales order.
Bacteriophages are the most abundant microorganism on Earth and coexist with the bacterial population. They can destroy bacterial cells successfully and effectively. They cannot enter mammalian cells which saves the eukaryotic cells from lytic phage activity. In conclusion, phage therapy may have many potential applications in microbiology and human medicine with no side effect on eukaryotic cells.

Abstract: Introduction: Oxymorphone is similar in structure to morphine. It is used for the relief of pain that was approved by the Food and Drug Administration (FDA) in 2006, which may have side effects on few parts of the body. Aim: To illustrate the changes in biochemical parameters in response to the injection of oxymorphone in adult male rats. Materials and Methods: This research was carried out on 50 male adult Wistar rats which were divided into 5 groups that included 2, 4 and 6 mg/kg of Oxymorphone received groups, control group and normal saline received group. Injections were administered intraperitoneally via a catheter once a week for 56 days. After eight weeks, blood samples were collected using cardiac puncture method. Following serum preparation, enzymes and hormones levels were quantified using standard automated spectrophotometer especially photometric kinetic methods. All values were presented as mean±SEM. Statistical significance was evaluated by one-way analysis of variance (ANOVA, t-test) using IBM SPSS Statistics 20.0 for Windows. Results: The results demonstrate that serum levels of Adrenocorticotropic Hormone (ACTH), cortisol, aldosterone and Thyroid-Stimulating Hormone (TSH) increased in all groups which received oxymorphone. The serum levels of Creatine Kinase (CK) had significant decrease in all exposed groups. Oxymorphone had no statistically significant impact on the serum levels of Alkaline Phosphatase (ALP). Serum levels of Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), T3 and T4 had a significant change in group which received 6 mg/kg of oxymorphone. No definite changes in other groups. Conclusion: Exposure to 2, 4 and 6 mg/kg of oxymorphone may lead to short and long-term side effects. These effects can be therapeutic effects for a range of patients and can also be very deadly for a group of patients with unbalanced serum levels of special enzymes or hormones.
