Abstract
Background: Multiple drug use is frequently considered to be hazardous for the elderly because of their greater vulnerability to the complications. The purpose of this study was to determine the prevalence of polypharmacy in Tehran and to assess the relative demographic characteristics of patients.
Methods: In a cross-sectional study 400 persons aging 55 years and older were interviewed in order to determine the presence of polypharmacy (daily intake of three or more drugs). The cases were randomly selected and asked to answer a questionnaire through interview at home. The questionnaire contained questions about all taking drugs, pattern of using each drug and also patients' personal, social and medical history. Chi-square and fisher exact tests and determination of odds ratios were used in order to data analysis.
Results: Medium number of drugs used was 3.4 ± 1.9 in studied cases and %39.6 of cases were exposed to polypharmacy. The prevalence of physician prescribed drug usage was observed to be increased by increasing number of total used drugs in each case (P<0.002). The most commonly used drugs were A.S.A, Atenolol and propranolol and these drugs were prescribed by physician in over than %90 of cases. There was a positive correlations between polypharmacy with referring to multiple physicians (OR=1.96, CI 95%, 1.28-2.98) (P<0.002) and adverse drug reactions (OR=2.44, CI 95%, 1.47-4.05) (P<0.001). Polypharmacy was more prevalent in the age group of 65-75 years (P<0.04) and lower levels of education (P<0.004) and less prevalent in the group with moderate income (P<0.001).
Conclusion: Polypharmacy is common among adults aging 55 years and more in Tehran and is affected by age, education level and economic status.

Abstract
Background: TPS is one of the tumor markers which has specially been considered due to its exclusive physiological characteristics like its easy measurement in serum of cancer patients. This study has been due to evaluate the efficiency of this tumor marker in the prognosis, treatment control and follow up of patients with gastrointestinal cancers including esophagus, stomach and colorectal.
Methods: TPS has been measured in 109 persons including 28 healthy people and 81 patients with different gastrointestinal malignancies which were composed of 38 patients with esophageal cancer, 20 ones with stomach cancer and 23 ones with colorectal cancer. Sampling has been done in three times depending on treatment methods. TPS has been measured with ELISA in samples which contend of 2 to 3 ml of serum from patients and the health.
Results: The obtained results, demonstrate the obvious changes in TPS serum level in patients underwent various treatment procedures.
Conclusion: The results have revealed that the serum TPS is not only as a measure of prognosis but also would be helpful in follow up and treatment control of the disease. Moreover the results has shown that serological analysis can be settled in the diagnosis and follow up with production of polyclonal antibody against TPS gene family and planning appropriate pattern.

Abstract
Background: Bone remodeling has always been the goal of surgeons for a long time. Recently, it was shown that statins that are commonly prescribed for lowering cholesterol also have beneficial effects on bone healing. Therefore, the present study was undertaken to evaluate the probable effects of atorvastatin on osteogenesis in the rat femur.
Methods: This experimental study was conducted on 30 male Sprague-Dawley (SD) rats. The animals were divided randomly into one control and two experiment groups. After induction of anesthesia, a hole of 2 mm in diameter was made in femur width. The control group received physiological serum but the experiment groups one and two, respectively, received 10 and 20 mg/kg/PO of atorvastatin on daily basis. After euthanizing the rats, histopathological and histomorphometrical evaluations of the bones were performed 45 days after the intervention.
Results: In the control group, the defects seemed to be filled with woven bone and bone marrow, depictive of a poor osteogenic activity. In the experiment groups, many osteoblast groupings and young bone trabeculae had been formed and bone trabeculae were more organized. Histomorphometric results, showed that atorvastatin had significantly promoted bone healing in the experiment groups compared with the controls (P<0.001). Moreover, the analysis showed that atorvastatin had more significant effects in group three receiving high doses of the medication in comparison with group two (P<0.001).
Conclusion: The findings of this study showed that atorvastatin is capable of stimulating osteogenesis in rats.

Abstract
Background: Despite the considerable advances in acquired immunodeficiency syndrome (AIDS) treatment and management, finding the cure for this disease has been hindered by emerging challenges such as virus resistance and treatment failures. The purpose of this study is to compare the cytokine profiles of patients with successful treatment and patients with unsuccessful treatment to gain a better understanding of treatment failure mechanisms.
Methods: Sixty-nine human immunodeficiency virus (HIV) positive patients who were referred to the west health center of Tehran between September 2018 and March 2021 were included in this study. Blood CD4+ cell count and viral load was measured using the flow cytometry and quantitative real-time polymerase chain reaction (RT-qPCR) methods respectively. Based on the viral load test results patients were divided into successful treatment (viral load<200 copies/ml, n=36) and unsuccessful treatment (viral load>200 copies/ml, n=33) groups. Subsequently, tumor necrosis factor-α (TNF-α) and interleukin-10 (IL-10) serum levels were measured using the enzyme-linked immunosorbent assay (ELISA) method.
Results: Analysis of data revealed that there was no difference in demographic data, medical history and clinical laboratory test results between the study groups. Elisa test results showed that serum TNF-α levels were significantly higher in the unsuccessful treatment group compared to the successful treatment group (10.43±10.17 vs 5.37±5.25, P=0.01) but no differences were observed in IL-10 levels between the study groups. Furthermore, age and sex-adjusted linear regression models showed that non-nucleoside reverse-transcriptase inhibitors (NNRTI)-based treatment regimen is positively associated with serum IL-10 levels in patients with unsuccessful treatment (B coefficient 10.88 (95% CI: 1.32-20.45), P=0.03). Moreover, based on the results of the linear regression models, no relationship between HIV viral load and serum IL-10 and TNF-α level was observed.

Conclusion: Results of this study showcased the importance of TNF-α in disease progression and treatment failure. Further future studies regarding this relationship can provide vital information in AIDS treatment research.
