    This paper presents a 2-D FFT removal algorithm for reducing the periodic noise in natural and strain images. For the periodic pattern of the artifacts, we apply the 2-D FFT on the strain and natural images to extract and remove the peaks which are corresponding to periodic noise in the frequency domain. Further the mean filter applied to get more effective results. The performance of the proposed method is tested on both natural and strain images. The results of proposed method is compared with the mean filter based periodic noise removal and found that the proposed method significantly improved for the noise removal

    In medical image processing, image denoising has become a very essential exercise all through the diagnose. Negotiation between the preservation of useful diagnostic information and noise suppression must be treasured in medical images. In case of ultrasonic images a special type of acoustic noise, technically known as speckle noise, is the major factor of image quality degradation. Many denoising techniques have been proposed for effective suppression of speckle noise. Removing noise from the original image or signal is still a challenging problem for researchers. In this paper, a Curvelet transform based denoising with improved thresholds is proposed for ultrasound images

    Background GLORIA-AF (Global Registry on Long-Term Oral Antithrombotic Treatment in Patients with Atrial Fibrillation) is a prospective, global registry program describing antithrombotic treatment patterns in patients with newly diagnosed nonvalvular atrial fibrillation at risk of stroke. Phase 2 began when dabigatran, the first non\u2013vitamin K antagonist oral anticoagulant (NOAC), became available. Objectives This study sought to describe phase 2 baseline data and compare these with the pre-NOAC era collected during phase&nbsp;1. Methods During phase 2, 15,641 consenting patients were enrolled (November 2011 to December 2014); 15,092 were eligible. This pre-specified cross-sectional analysis describes eligible patients\u2019 baseline characteristics. Atrial fibrillation&nbsp;disease characteristics, medical outcomes, and concomitant diseases and medications were collected. Data were analyzed using descriptive statistics. Results Of the total patients, 45.5% were female; median age was 71 (interquartile range: 64, 78) years. Patients were from Europe (47.1%), North America (22.5%), Asia (20.3%), Latin America (6.0%), and the Middle East/Africa (4.0%). Most had high stroke risk (CHA2DS2-VASc [Congestive heart failure, Hypertension, Age&nbsp; 6575 years, Diabetes mellitus, previous Stroke, Vascular disease, Age 65 to 74 years, Sex category] score&nbsp; 652; 86.1%); 13.9% had moderate risk (CHA2DS2-VASc&nbsp;= 1). Overall, 79.9% received oral anticoagulants, of whom 47.6% received NOAC and 32.3% vitamin K antagonists (VKA); 12.1% received antiplatelet agents; 7.8% received no antithrombotic treatment. For comparison, the proportion of phase 1 patients (of N&nbsp;= 1,063 all eligible) prescribed VKA was 32.8%, acetylsalicylic acid 41.7%, and no therapy 20.2%. In Europe in phase 2, treatment with NOAC was more common than VKA (52.3% and 37.8%, respectively); 6.0% of patients received antiplatelet treatment; and 3.8% received no antithrombotic treatment. In North America, 52.1%, 26.2%, and 14.0% of patients received NOAC, VKA, and antiplatelet drugs, respectively; 7.5% received no antithrombotic treatment. NOAC use was less common in Asia (27.7%), where 27.5% of patients received VKA, 25.0% antiplatelet drugs, and 19.8% no antithrombotic treatment. Conclusions The baseline data from GLORIA-AF phase 2 demonstrate that in newly diagnosed nonvalvular atrial fibrillation patients, NOAC have been highly adopted into practice, becoming more frequently prescribed than VKA in&nbsp;Europe and North America. Worldwide, however, a large proportion of patients remain undertreated, particularly in&nbsp;Asia&nbsp;and North America.

    Background : Communicable disease surveillance is to have baseline data which will be helpful for planning and also for identifying epidemics under non-evident conditions. Objective : To delineate the pattern of occurrence of communicable diseases so as to enable early identification, followed by appropriate and timely response to outbreaks. Materials and Methods :Reports of listed communicable diseases from various departments and centers of Government Medical College, Chandigarh, involved in clinical care and laboratory diagnosis, were collected by the Department of Community Medicine on a weekly basis. Analysis of surveillance data was done for a period of 1 year - including reports from March 2005 to February 2006. Statistical Analysis : Percentage, normal test of proportions, time series analysis. Results : Out of 19,378 cases of various communicable diseases, 11,575, i.e., more than half, were dealt with by health centers. Thus maximum cases of acute respiratory infections (ARIs) [8,278 (71.87%)] and acute diarrheal diseases (ADDs) [3,148 (54.4%)] were dealt with by health centers. Of 19,378 cases, 11,518 (59.44%) were of ARIs, 5,786 (29.86%) of ADDs and 550 (2.84%) of pulmonary tuberculosis. There was no significant difference in the incidence of either disease between two sexes. Most, i.e., 4,413 (38.31%), cases of ARIs and 512 (86.49%) cases of pneumonia were reported in winter; ADDs - 2,607 (45.05%) in summer; and typhoid - 94 (41.04%) in the monsoon season. Conclusion : Maximum workload of common communicable diseases was borne by health centers. The most common morbidity was ARIs, followed by ADDs and pulmonary tuberculosis. No significant gender predilection was seen. Overall reporting of communicable diseases observed in three different seasons was found to show a gradual increase from winter to summer through monsoon. Some specific seasonal trends were demonstrated by various morbidities

    No full text
    Introduction: Cancer is a leading public health problem worldwide. Contributing factors include lack of awareness regarding cancer and improper help seeking behavior. Objective: To assess the awareness regarding early warning signs of cancer, its risk factors and anticipated barriers in seeking help. Methodology: A community-based cross-sectional study was conducted among 470 study participants. Trained workers administered a standardized tool to respondents after obtaining their informed consent. Epi Info software for windows version 7.2 was used for the analysis. Results: Overall, merely 7.7% (36/470) of the study respondents were aware of all the nine warning signs of cancer. The most commonly known early warning sign of cancer was “unexplained swelling” (58.3%). Further, although majority knew that cigarette smoking is a risk factor for cancer (90.4%), very few were aware about the role of inadequate physical activity (9.3%) and diet devoid of adequate amounts of fruits and vegetables (11.9%). There were few anticipated barriers in seeking help such as embarrassment (13.2%) and difficult to interact with a doctor (7.9%). Conclusion: There was inadequate awareness about cancer but a favorable help-seeking behavior. It is, therefore, recommended that health-care professionals should scale up efforts for disseminating information regarding cancer among the people
