Considering Frequency of Anserine Bursitis in Osteoarthritis Patients who Referred to Ardabil Imam Khomeini Hospital and Royan Specialists Clinic with Knee Pain
No full textBackground and Objective:. Knee pain is a very common disease in the elderly, which is often attributed to osteoarthritis [1]. But Anserine Bursitis also can cause knee pain, especially in OA patients. [2]. The major symptoms of knee osteoarthritis are pain, morning stiffness, limited range of motion and joint hypersensitivity [8]. The term " Anserine " is referred to the joint site of Sartorius, Grasiliss, and Semitendinios in the proximal area of the tibia. The aim of this study is to determine the frequency of Anserine Bursitis in patients with osteoarthritis, that, complain of knee pain,come to the rheumatology clinic of Imam Khomeini Hospital and the Royan clinic with using ultrasonography.
Methods:This study included patients with definitive knee osteoarthritis based on radiographic and clinical findings and were referred to Imam Khomeini Hospital clinic or Ardabil Royan Clinic with complain of knee pain then ultrasonography was done.The sample number was 245. Osteoarthritis was divided into 4 groups based on the radiographic classification of Kellgren-Lawrence. [22] The severity of knee pain was also determined by the Visual Analogue Scale (VAS). The results with demographic data (sex and age), height and weight of patients were recorded in the data collection checklists. The body mass index was calculated using the formula weight in kilograms divided by height-meter squared. Hemograms, biochemical values, and sedimentation and C-reactive protein were also determined for all patients.In this study we use Independent sample t test ,Chi-squared test and spss 22 software.
Results: 175 out of 245 patients were diagnosed with anserin bursitis, and the results showed a 71% prevalence of Anserin bursitis in patients with knee pain. The analysis showed that there is a significant relationship(Pvalue0.03) between age and the risk of anserin bursitis. There was a direct correlation between the Anserine Bursitis with BMI(P value0.01) and there was a significant relationship(Pvalue0.03) between the degree of osteoarthritis and Anserin bursitis. The results showed that the risk factors for osteoarthritis and Anserin bursitis, including obesity and the lifestyle, are very poor in our country. The high diagnostic power (about 85%) of the clinical examination was significant in Anserine Bursitis compared with ultrasonography.
Conclusion. The high prevalence of anserine bursitis in patients studied indicates the importance of this issue and the need for attention by physician as one of knee pain reasons. Since the clinical examination has a significant diagnostic power in the detection of Anserin bursitis, it is recommended that special attention be paid to the clinical examination. Attention to the risk factors in the country such as obesity, the use of toilets and so on, which can be controlled and can be prevented
A Comparative Study for the Removal of Methylene Blue Dye from Aqueous Solution by Novel Activated Carbon Based Adsorbents
Get PDFThis study was conducted to assess the ability of the studied adsorbent, i.e. raw oak fruit hulls and the activated carbon prepared from oak fruit hull for removing the Methylene blue (MB) from aqueous solution. This study was conducted under various effective parameters, e.g., contact time, pH, MB concentration, adsorbent concentration. The optimum amount of each parameter was determined and the isotherm and kinetic studies were also carried out. The results revealed that the best results for MB removal efficiency are observed using the activated carbon prepared from oak fruit hulls. It was also observed that increasing the contact time, pH and adsorbent concentration provides better condition to enhance the dye removal efficiency and increasing the MB, hence reducing the removal efficiency. Furthermore, the results also clarified that the best models to describe the MB adsorption onto the raw oak fruit hulls and activated carbon are the Langmuir model 1 (R2=0.9971) and Langmuir 2 (R2=0.7631), respectively. In addition, the adsorption of MB onto the raw oak fruit hulls and activated carbon are better fitted to pseudo-second-order model and zero-order model, respectively. Finally, it can be concluded that the activated carbon prepared from the raw oak fruit hulls is more valuble than the raw oak fruit hull for removing the MB

Genetic variants within Ninjurin 2 gene are associated with risk of ischemic stroke in Iranian population
No full textPrevious genetic and epidemiological studies have shown the contribution of genetic factors in conferring the risk of ischemic stroke. Among the acknowledged risk factors of stroke are the single nucleotide polymorphisms (SNPs) near Ninjurin 2 (NINJ2) gene which encodes a surface adhesion protein. In the current study, we investigated the role of two SNPs near this gene in ischemic stroke in Iranian population. The frequency of the A allele of the rs11833579 was significantly lower in cases compared with controls (OR (95% CI) = 0.68 (0.54–0.86), adjusted P value = 0.002). The rs11833579 was significantly associated with risk of stroke in co-dominant (AA vs. GG: OR (95% CI) = 0.39 (0.23–0.66), adjusted P value = 0.003) and recessive (OR (95% CI) = 0.44 (0.27–0.72), adjusted P value = 0.001) models. The rs3809263 was associated with risk of stroke in dominant model (OR (95% CI) = 1.5 (1.09–2.06), adjusted P value = 0.02). The A C haplotype (rs11833579 and rs3809263) decreased the risk of stroke (OR (95% CI) = 0.72 (0.57–0.91), adjusted P value = 0.03), while the G T haplotype conferred susceptibility to stroke (OR (95% CI) = 1.42 (1.11–1.82), adjusted P value = 0.02). Consequently, the present case-control study supports the role of NINJ2 as a risk locus for ischemic stroke in Iranian population

The global, regional, and national burden of stomach cancer in 195 countries, 1990–2017: a systematic analysis for the Global Burden of Disease study 2017
No full textBackground
Stomach cancer is a major health problem in many countries. Understanding the current burden of stomach cancer and the differential trends across various locations is essential for formulating effective preventive strategies. We report on the incidence, mortality, and disability-adjusted life-years (DALYs) due to stomach cancer in 195 countries and territories from 21 regions between 1990 and 2017.
Methods
Estimates from GBD 2017 were used to analyse the incidence, mortality, and DALYs due to stomach cancer at the global, regional, and national levels. The rates were standardised to the GBD world population and reported per 100 000 population as age-standardised incidence rates, age-standardised death rates, and age-standardised DALY rates. All estimates were generated with 95% uncertainty intervals (UIs).
Findings
In 2017, more than 1·22 million (95% UI 1·19–1·25) incident cases of stomach cancer occurred worldwide, and nearly 865 000 people (848 000–885 000) died of stomach cancer, contributing to 19·1 million (18·7–19·6) DALYs. The highest age-standardised incidence rates in 2017 were seen in the high-income Asia Pacific (29·5, 28·2–31·0 per 100 000 population) and east Asia (28·6, 27·3–30·0 per 100 000 population) regions, with nearly half of the global incident cases occurring in China. Compared with 1990, in 2017 more than 356 000 more incident cases of stomach cancer were estimated, leading to nearly 96 000 more deaths. Despite the increase in absolute numbers, the worldwide age-standardised rates of stomach cancer (incidence, deaths, and DALYs) have declined since 1990. The drop in the disease burden was associated with improved Socio-demographic Index. Globally, 38·2% (21·1–57·8) of the age-standardised DALYs were attributable to high-sodium diet in both sexes combined, and 24·5% (20·0–28·9) of the age-standardised DALYs were attributable to smoking in males.
Interpretation
Our findings provide insight into the changing burden of stomach cancer, which is useful in planning local strategies and monitoring their progress. To this end, specific local strategies should be tailored to each country's risk factor profile. Beyond the current decline in age-standardised incidence and death rates, a decrease in the absolute number of cases and deaths will be possible if the burden in east Asia, where currently almost half of the incident cases and deaths occur, is further reduced
Adsorption of basic violet 16 from aqueous solutions by Magnetic graphene oxide.
Get PDFBackground and Objective: Dye wastewater from the textile manufacturing may show toxic or carcinogenic effects on organism when discharged into rivers and lakes changing their biological life. Therefore, in this study, the removal of basic violet 16 was investigated by a magnetite graphene oxide nanocomposites (Fe3O4@GO) optimizing by response surface methodology based on Box-Behnken method.
Methods: Fe3O4@GO nanocomposite was prepared by a facile in situ co-precipitation strategy, resulting in a suitable composite for the application of graphene oxide in wastewater treatment. The structure and morphology of the Fe3O4 @GO adsorbent were investigated using XRD, FT-IR, SEM, BET and VSM techniques.
Results: In the SEM images be observed that the Fe3O4 NPs are distributed between the GO sheets and empty spaces with large pores between GO sheets are visible, also the results of the FT-IR analysis showed that the largest group was carboxyl group. The various parameters in the process, such as pH, reaction time, adsorbent dose and initial concentration of dye, were evaluated. The proposed model (quadratic) with a high correlation coefficient (R2 =0.98) and (R2adj =0.97) was approved. Favorable removal of dye (efficiency: 95.03%.) was obtained under following conditions: the dye concentration of 62.5 mg L-1, the absorbance of 0.2 g L-1, the reaction time of 60 minutes and solution pH of 7.5.
Conclusion: The results of the study of adsorption isotherms and kinetics showed that the adsorption process follows the Langmuir isotherm (R2: 0.98) and the pseudo-second-order kinetic (R2: 0.99) models. The present study showed that the Fe3O4 @GO adsorbent has high efficiency in removal of violet 16
