The Effectiveness of Sovodak in the Treatment of Patients with Chronic Hepatitis C

Background: Recently, interferon-free treatment has been considered for the treatment of chronic hepatitis C due to their high therapeutic success and lack of serious side effects. The combination of Sofosbuvir and Daclatasvir is effective in the treatment of the disease because of its pan-genotype. In the present study, the effectiveness of Sovodak, which is a combination of the aforementioned two drugs in one tablet, in the treatment of patients with chronic hepatitis C and cirrhosis was investigated. Methods: Patients with chronic hepatitis C whose diagnosis was confirmed by HCV RNA–PCR test were included in the study. These patients received one Sovodak tablet daily (for 12 weeks for non-cirrhotic patients and 24 weeks for cirrhotic patients). Sustained virologic response (SVR) was assessed by PCR test 12 weeks after the end of the treatment and one year later. Also, serum levels of liver enzymes, platelet count, and liver stiffness (using elastography method) were measured and their levels were compared before and after treatment in patients. Results: Findings related to the PCR test in patients showed that the level of SVR was 100% in patients 12 weeks after treatment (SVR-12). In three cirrhotic patients who received only 12 weeks of drug treatment, the disease recurred a year later. According to the results, ALT and AST serum levels were significantly decreased (P < 0.001), and platelet count level was increased (P < 0.001) one year after the end of the treatment period. Also, the liver stiffness index measured using FibroScan was significantly decreased in patients 12 weeks after the end of the treatment (P < 0.001). Conclusion: The results of this study, in line with other studies, showed the effective role of Sovodak in completely eliminating the HCV virus in patients with chronic hepatitis C. Cirrhotic patients need to receive treatment for at least six months. Key words: Sovodak, hepatitis C, sustained virologic response, effectiveness, liver cirrhosi

Evaluation of Lipid Profile, Apo B/ Apo A Ratio and Lpa and its Relationship with Cognitive Disorders in the Older Adults: Birjand Longitudinal Aging Study

Introduction: Accurate and timely diagnosis of mild cognitive disorders is essential to prevent their progression to dementia. This study aimed to determine the relationship among the serum levels of lipid markers of cognitive disorders in older adults in Birjand. Materials and Methods: The community-based cohort study was performed on 1400 older adults population (60 years and older) living in urban and rural areas of Birjand, among whom 242 older adults were selected by multi-stage random sampling; the Mini-Mental State Examination Cognitive Disorders Questionnaire was completed, and five cc of blood samples were taken to assess Triglyceride, Cholesterol, Low density lipoprotein, High-density lipoprotein, lipoprotein a, Apo lipoprotein A, and Apo lipoprotein B. Results: The mean age of participants was 70.6± 6.96 years. 55.4% were women. The level of MMSE was significantly different based on the demographic information. Mean serum levels of Lipid profile, Apo B/ Apo A Ratio, and LP a, were not significantly different from MMSE. Conclusion: The study showed a significant relationship between demographic information and MMSE level, so it can be used to improve the cognitive level of older adults by changing their life situation, marital status, and education. However, the parameters of Lipid profile, Apo B/ Apo A Ratio, and LP a are not used to diagnose cognitive disorders in older adults

National and sub-national trend of prevalence and burden of dementia in Iran, from 1990 to 2013; Study protocol

Background: Dementia is a disabling syndrome, which generally affects aged population more than any other age groups. This syndrome has a growing prevalence and incidence worldwide. The prevalence and burden of this group of diseases in Iran have not been estimated in a community-based study yet. This paper aims to explain the systematic approach, data sources, research methodology, and statistical analysis that will be used to quantify the prevalence and burden of dementia at national and sub-national levels. Methods: This is the protocol of a secondary data study that explains the design and method of conducting the study. We will use several sources of data that will include a systematic review of articles and gray literature which have reported the prevalence or incidence of dementia and its uncertainty at national and sub-national levels in Iran, in addition to data about dementia-specific drug sales per each year at provincial levels, as well as data extracted from 23 million health insurance prescriptions over 8 years and some data from medical documents of Iranian Alzheimer's Association members. The technical groups of National and Sub-national Burden of Disease will collect some covariate data, such as age and sex structure of population, urbanization status, mean years of schooling, plasma cholesterol, fasting plasma glucose, and systolic and diastolic blood pressure at provincial levels which will be used in our models. Two statistical models, namely spatio-temporal and hierarchical autoregressive models, will be used for interpolation and extrapolation of missing data. Conclusion: It seems that the study of national and subnational burden of dementia could provide more accurate estimation of prevalence and burden of dementia in Iran with an acceptable level of uncertainty than the previous studies

Comparison of therapeutic effects of encapsulated Mesenchymal stem cells in Aloe vera gel and Chitosan-based gel in healing of grade-II burn injuries

Treatment of burn injuries with Mesenchymal stem cells (MSCs) is a great promise due to their unique properties. As two natural and functional wound dressing, Chitosan and Aloe-Vera gel assist wound regeneration by providing a proper environment. In the current study, we aimed to compare the effect of encapsulated BMSCs in Chitosan-based gel and Aloe-Vera gel on the healing of grade-II burn injuries compared to other groups in the rat. After creation of a 2 � 2 cm grade-II burn on dorsal skin of rats, treatments were performed for each group. The wound closure rate and healing properties were evaluated by histopathological analysis on 7, 14, 21 and, 28 days post-treatment. The expression rate of VEGF, Collagen-I and Collagen-III genes was also assessed on days 3, 7, 14, 21 and 28 performing qRT-PCR. The full wound healing with inconsiderable scar formation was achieved for Aloe-vera/BMSCs and Chitosan/BMSCs group on 28th day post-treatment. Pathological results also demonstrated the highest angiogenesis and granulation tissue formation for Aloe-vera/BMSCs and Chitosan/BMSCs groups respectively. The expression level of VEGF, Collagen-I, and Collagen-III genes was significantly higher in these groups on days 14 and 21, compared to other groups. Results demonstrated the synergistic effect of BMSCs when combined with Chitosan or Aloe-vera gel enhanced the healing process of wound healing more than chitosan gel treatment. Therefore, this gel can be considered as effective approaches for treatment of burn injuries

Socioeconomic inequality of overweight and obesity of the elderly in Iran: Bushehr Elderly Health (BEH) Program

Background: The objective of this population-based, large sample size study was to investigate the socioeconomic inequality of overweight and obesity among the elderly in Iran. Methods: Baseline data of 3000 persons aged ≥60 years who participated in the Bushehr Elderly Health (BEH) program was analyzed. Overweight and obesity were defined as a body mass index (BMI) equal to or higher than 25 and 30, respectively. Socioeconomic status (SES) was measured by an asset index, constructed using principal component analysis, income, education level, and employment status. The Concentration Index and the Lorenz curve were used to illustrate the levels of inequality for overweight and obesity by gender. Results: The frequencies among men and women were, respectively, 840 (57.7%) and 1131 (73.2%), P < 0.001, for overweight, and 211 (14.7%) and 511 (33.7%), P < 0.001, for obesity. There were direct associations between asset index quintiles and both overweight and obesity among both genders (Ps for trend <0.01) except for obesity among men (P for trend = 0.118). The overall Concentration Indices for overweight and obesity were 0.031 (95%CI = 0.016–0.046, P < 0. 001) and 0.041 (95%CI = 0.004–0.078, p = 0.028), respectively. Conclusion: Findings support the direct relationship between SES and obesity among women as previously reported in developing countries.

Overlap between Osteosarcopenia and Frailty and their Association with Poor Health Conditions: The Bushehr Elderly Health Program

Background The aim of this study was to investigate the association of osteosarcopenia with frailty and poor health conditions among older Iranian adults. Methods This cross-sectional study analyzed data from the Bushehr Elderly Health Program. Osteosarcopenia was defined as the presence of osteopenia/osteoporosis and sarcopenia, while the Fried criteria were used to assess frailty. We assessed the history of falls and health-related quality of life (HRQoL), including physical and mental component summaries (PCS and MCS, respectively), history of fractures, activities of daily living (ADL), and instrumental activities of daily living (IADL), as indicators of poor health conditions. Results This study included a total of 2,371 older adults. The prevalence rates of osteosarcopenia-only, frailty-only, and osteosarcopenia with frailty were 17.4%, 3%, and 4.8%, respectively. The prevalence of a history of falls, poor ADL, and poor IADL was significantly higher in the frailty-only and osteosarcopenia with frailty groups. Osteosarcopenia with frailty was significantly associated with a history of falls (adjusted odds ratio [adjOR]=1.94; 95% confidence interval [CI], 1.20–3.15), poor ADL (adjOR=2.85; 95% CI, 1.81–4.50), and poor IADL (adjOR=5.09; 95% CI, 2.85–9.11). However, the frailty-only group also showed an association with falls and poor ADL and IADL. Only osteosarcopenia was associated with an increased OR for fracture. Frailty had the greatest effect on the MCS and PCS scores, whereas osteosarcopenia with frailty had a moderate impact. Conclusion Osteosarcopenia with frailty significantly increased the odds of falls, poor ADL, poor IADL, and lower HRQoL compared with the robust group. Combined osteosarcopenia and frailty were not associated with poor health. These findings indicate the importance of diagnosing osteosarcopenia and frailty as separate entities to provide appropriate interventions and treatment

Bushehr Elderly Health (BEH) Programme, phase I (cardiovascular system)

Purpose: The main objective of the Bushehr Elderly Health Programme, in its first phase, is to investigate the prevalence of cardiovascular risk factors and their association with major adverse cardiovascular events. Participants: Between March 2013 and October 2014, a total of 3000 men and women aged ≥60 years, residing in Bushehr, Iran, participated in this prospective cohort study ( participation rate=90.2%). Findings to date: Baseline data on risk factors, including demographic and socioeconomic status, smoking and medical history, were collected through a modified WHO MONICA questionnaire. Vital signs and anthropometric measures, including systolic and diastolic blood pressure, weight, height, and waist and hip circumference, were also measured. 12-lead electrocardiography and echocardiography were conducted on all participants, and total of 10 cc venous blood was taken, and sera was separated and stored at –80°C for possible future use. Preliminary data analyses showed a noticeably higher prevalence of risk factors among older women compared to that in men. Future plans: Risk factor assessments will be repeated every 5 years, and the participantswill be followed during the study to measure the occurrence of major adverse cardiac events. Moreover, the second phase, which includes investigation of bone health and cognition in the elderly, was started in September 2015. Data are available at the Persian Gulf Biomedical Research Institute, Bushehr University of Medical Sciences, Bushehr, Iran, for any collaboratio

An overview of burst, buckling, durability and corrosion analysis of lightweight FRP composite pipes and their applicability

© 2019 Elsevier Ltd. All rights reserved.The main aim of this review article was to address the performance of filament wound fibre reinforced polymer (FRP) composite pipes and their critical properties, such as burst, buckling, durability and corrosion. The importance of process parameters concerning merits and demerits of the manufacturing methods was discussed for the better-quality performance. Burst analysis revealed that the winding angle of ±55° was observed to be optimum with minimum failure mechanisms, such as matrix cracking, whitening, leakage and fracture. The reduction of buckling effect was reported in case of lower hoop stress value in the hoop to axial stress ratio against axial, compression and torsion. A significant improvement in energy absorption was observed in the hybrid composite pipes with the effect of thermal treatment. However, the varying winding angle in FRP pipe fabrication was reported as an influencing factor affecting all the aforementioned properties. Almost 90% of the reviewed studies was done using E-glass/epoxy materials for the composite pipe production. By overcoming associated limitations, such as replacing synthetic materials, designing new material combinations and cost-benefit analysis, the production cost of the lightweight FRP composite pipes can be decreased for the real-time applications.Peer reviewe
