Facilitating and inhibiting factors related to treatment adherence in women with polycystic ovary syndrome: a qualitative study

Background: Adherence issues in PCOS patients have not been examined thoroughly. Patients report prolonged periods of treatment and side effects of drug as the most common reason for withdrawal from treatment. To improve the effective management of PCOS patients, it is fundamental to understand facilitating and inhibiting factors to treatment adherence. Objective: to explore facilitating /inhibiting factors related to treatment adherence among PCOS patients. Material and Methods: This was a qualitative study with a purposive sample of women with confirmed diagnosis of PCOS. The data were collected via 20 in-depth semi-structured interviews with women aged between 21 to 34. A qualitative content analysis was used to analyze the data. Results: Five themes were identified which described different types of facilitating /inhibiting factors to treatment adherence. Inhibiting factors included financial issues, patient-related, disease-related, health care provider-related factors; social factors were found to be both facilitating and inhibiting. Conclusion: The findings suggest that successful adherence to PCOS treatment is highly dependent on patients recognizing and adapting to financial, social, and health care related inhibiting factors. It is also crucial for clinicians and policy makers to recognize these key inhibiting factors in order to improve treatment outcomes Keywords: polycystic ovarian syndrome, adherence, qualitative researc

Study of mycoflora in cultured Indian white shrimp (Penaeus indicus) in Abadan, Iran

The development of the commercial culture of penaeid shrimps has been accompanied by the occurrence of infectious and noninfectious diseases. The most important penaeid diseases are caused by organisms that are part of the normal microflora of penaeids. In 1998, the samples were collected from five farms in Ghofase area (Ahadan) 2-5 ponds in each farm. The shrimps of these ponds were preserved in full hygienic conditions, from each pond, at least 5 samples were collected and then transferred to the Aquatic Diseases Laboratory of Khouzestan Fisheries Research Center. The main tissues of Gill, Hemolymph, Hepatopancreas and cuticle of live-shrimps were studied in the laboratory. In this research, a total of 40 fungal species were isolated from different tissues with high abundance in Hepatopancrease (19 species) and Hemolymph (12 species). Aspergillus niger was identified as the most abundant species

MicroRNA-129-1 acts as tumour suppressor and induces cell cycle arrest of GBM cancer cells through targeting IGF2BP3 and MAPK1

Background MicroRNA-129-1 (miR-129-1) seems to behave as a tumour suppressor since its decreased expression is associated with different tumours such as glioblastoma multiforme (GBM). GBM is the most common form of brain tumours originating from glial cells. The impact of miR-129-1 downregulation on GBM pathogenesis has yet to be elucidated. Methods MiR-129-1 was overexpressed in GBM cells, and its effect on proliferation was investigated by cell cycle assay. MiR-129-1 predicted targets (CDK6, IGF1, HDAC2, IGF2BP3 and MAPK1) were also evaluated by western blot and luciferase assay. Results Restoration of miR-129-1 reduced cell proliferation and induced G1 accumulation, significantly. Several functional assays confirmed IGF2BP3, MAPK1 and CDK6 as targets of miR-129-1. Despite the fact that IGF1 expression can be suppressed by miR-129-1, through 30-untranslated region complementary sequence, we could not find any association between IGF1 expression and GBM. MiR-129-1 expression inversely correlates with CDK6, IGF2BP3 and MAPK1 in primary clinical samples. Conclusion This is the first study to propose miR129-1 as a negative regulator of IGF2BP3 and MAPK1 and also a cell cycle arrest inducer in GBM cells. Our data suggests miR-129-1 as a potential tumour suppressor and presents a rationale for the use of miR-129-1 as a novel strategy to improve treatment response in GBM

Trends of 28 days case fatality rate after first acute myocardial infarction in Isfahan, Iran, from 2000 to 2009

Background: The purpose of the present study was the analysis of the trends in case fatality rate of acute myocardial infarction (AMI) in Isfahan, Iran. This analysis was performed based on gender, age groups, and type of AMI according to the International Classification of Diseases, version 10, during 2000-2009. Methods: Disregarding the Multinational Monitoring of Trends and Determinants in Cardiovascular Disease (MONICA), this cohort study considered all AMI events registered between 2000 and 2009 in 13 hospitals in Isfahan. All patients were followed for 28 days. In order to assess the case fatality rate, the Kaplan-Meier analysis, and to compare survival rate, log-rank test were used. Using the Cox regression model, 28 days case fatality hazard ratio (HR) was calculated. Results: In total, 12,900 patients with first AMI were entered into the study. Among them, 9307 (72.10) were men and 3593 (27.90) women. The mean age in all patients increased from 61.36 ± 12.19 in 2000-2001 to 62.15 ± 12.74 in 2008-2009, (P = 0.0070); in women, from 65.38 ± 10.95 to 67.15 ± 11.72 (P = 0.0200), and in men, from 59.75 ± 12.29 to 59.84 ± 12.54 (P = 0.0170),. In addition, the 28 days case fatality rate in 2000-2009 had a steady descending trend. Thus, it decreased from 11.20 in 2000-2001 to 07.90 in 2008-2009; in men, from 09.20 to 06.70, and in women, from 16.10 to 10.90. During the study, HR of case fatality rate in 2000-2001 declined; therefore, in 2002-2003, it was 0.93 95% confidence interval (CI) = 0.77-1.11, in 2004-2005, 0.88 (95% CI = 0.73-1.04), in 2006-2007, 0.67 (95% CI = 0.56- 0.82), and in 2008-2009, 0.69 (95% CI = 0.56-0.82). Conclusion: In Isfahan, a reduction was observable in the trend of case fatality rate in both genders and all age groups. Thus, there was a 29.46% reduction in case fatality rate (27.17% in men, 32.29% in women) during the study period. © 2015, Isfahan University of Medical Sciences(IUMS). All rights reserved

Marine health of the Arabian Gulf: Drivers of pollution and assessment approaches focusing on desalination activities

The Arabian Gulf is one of the most adversely affected marine environments worldwide, which results from combined pollution drivers including climate change, oil and gas activities, and coastal anthropogenic disturbances. Desalination activities are one of the major marine pollution drivers regionally and internationally. Arabian Gulf countries represent a hotspot of desalination activities as they are responsible for nearly 50% of the global desalination capacity. Building desalination plants, up-taking seawater, and discharging untreated brine back into the sea adversely affects the biodiversity of the marine ecosystems. The present review attempted to reveal the potential negative effects of desalination plants on the Gulf's marine environments. We emphasised different conventional and innovative assessment tools used to assess the health of marine environments and evaluate the damage exerted by desalination activity in the Gulf. Finally, we suggested effective management approaches to tackle the issue including the significance of national regulations and regional cooperation

Hepatitis B/C virus co-infection in Iran: A seroepidemiological study

Background/aims: As hepatitis B and C virus have the same transmission routes, dual infection may occur. The aim of this study was to determine the seroprevalence of HCV in HBsAg-positive subjects. Methods: 139 HBsAg-positive subjects were enrolled in the study. Serum samples were tested using ELISA method for anti-HCV antibodies. Chi-square and Fisher's exact tests were used to compare the proportions. Results: There were 68 (48.9%) males and 71 (51.1%) females. The mean age was 41.89±11.30 years. One case was excluded because of inadequate blood sampling. Anti-HCV antibody was positive in 17 (12.3%) of the 138 remaining subjects. Seropositivity of HCV was similar between female and male patients (p=0.69). Conclusion: The seroprevalence of co-infection with hepatitis B virus and hepatitis C virus in our study was higher than such reports from some countries (Italy), but was in line with worldwide prevalence (>10%)

Mining recurrent concepts in data streams using the discrete Fourier transform

In this research we address the problem of capturing recurring concepts in a data stream environment. Recurrence capture enables the re-use of previously learned classifiers without the need for re-learning while providing for better accuracy during the concept recurrence interval. We capture concepts by applying the Discrete Fourier Transform (DFT) to Decision Tree classifiers to obtain highly compressed versions of the trees at concept drift points in the stream and store such trees in a repository for future use. Our empirical results on real world and synthetic data exhibiting varying degrees of recurrence show that the Fourier compressed trees are more robust to noise and are able to capture recurring concepts with higher precision than a meta learning approach that chooses to re-use classifiers in their originally occurring form

A Cost-Minimization Analysis of Day-Care Versus in-Patient Surgery for Five Most Common General Surgical Procedures

Objective: This study aimed to compare costs of Day-care versus in-patient surgery for five most common general surgical proce-dures in a general hospital in Iran. Methods: In this retrospective study the records of all patients who underwent five most common general surgical operations (in-cluding Hernia, Hemorrhoid, Fistula, Pilonidal Sinus and Varicocele) between March 2011 and March 2013 were reviewed. The data about costs of these procedures was collected by a checklist, designed by the authors, one year before and one year after establishing the Day-Care ward in the hospital. The checklist was designed on the basis of 14 financial items related to surgical patients. All costs were measured from the provider's perspective. Results: The results of this study showed that after implementing day-care surgery ward, inpatient care costs, such as medi-cine/drugs, physician visits, medical consumable, personnel and hotel, reduced significantly per each procedure. However, the costs directly associated with each surgery, such as drugs and consumable, surgeon's wage and anesthesia costs, between these two periods was not significantly different. The highest amount of savings was related to the personnel costs, with 997,000 IRR reductions. On average, total cost of each procedure was reduced by 2,031,358 IRR after implementation of day-care ward. Conclusion: The findings from this study demonstrate that day-care surgery is a cost saving method compared to in-patient surgery for five most common general surgical procedures. It is recommended that hospital managers consider establishing day-care ward and conducting surgical procedures, in particular elective general surgical procedures, in this regimen, to decrease hospital costs and to make hospital beds free, for other patients who are more in need of specialized medical and nursing skills
