“…Hemostasis imbalance in patients with CHD may be the primary pathomechanism, along with abnormal fibrin deposition and increased serum PAI-1 levels [ 5 ] . Furthermore, some have found a reverse association; for example, a population-based study found that male patients with CSCR had a significantly higher CHD rate than those without CSCR, suggesting that CSCR may be a potential risk factor for the development of CHD in men [ 23 ] . We found no significant association between CHD and CSCR, which may suggest that, if present, such an association may have been too weak to be detected in our sample.…”

Purpose: This study aimed to investigate the possible risk factors of central serous chorioretinopathy (CSCR) in an Iranian cohort. Methods: We recruited 39 consecutive CSCR cases and 80 age-matched controls with no ocular pathology from the same medical center from March 2019 to March 2021. Enrolled patients underwent complete ophthalmological examination and extensive history taking in a referral setting. Logistic regression analysis was performed to detect any possible association of potential risk factors with CSCR. Results: The mean age of CSCR patients was 40.69±7.71 years. The male-to-female ratio in cases and controls was 1:1.79 and 1.22:1, respectively. Logistic regression analysis revealed that alcohol consumption (odds ratio, OR: 62.0, P <0.001), smoking (OR: 4.0, 95% CI: 1.47-10.85, P <0.006), corticosteroid use (OR: 6.95, 95% CI: 2.64-18.28, P <0.001), and high psychological stress (OR: 13.34, 95% CI: 4.68-38.02, P <0.01) were significant risk factors for developing CSCR. Ischemic heart disease (P =0.550), hypertension (P =0.750), and hyperopia (P =0.467) were not associated with the risk of CSCR. The most common form of steroid use was oral in both groups. No pregnant female was present in the study sample, precluding the assessment of its potential association with CSCR.Conclusion: CSCR often affects individuals of productive working ages; thus, identifying its preventable risk factors is highly encouraged. Our results suggested that alcohol consumption, smoking, and high levels of psychological stress are independent, preventable risk factors for CSCR.

“…That data shown in Table V would account for the vast majority of the overall JPEG implementation complexity of Fig. 1 (see [17]), since other operations sometimes performed in association with JPEG compression such as color space conversion, down sampling, and block extraction are relatively inexpensive operations. Furthermore, in many systems color space conversion is not necessary since data is often available straight from camera modules (e.g., Cyclops platform [18]).…”

One of the most important goals of current and future sensor networks is energy-efficient communication of images. This paper presents a quantitative comparison between the energy costs associated with 1) direct transmission of uncompressed images and 2) sensor platform-based JPEG compression followed by transmission of the compressed image data. JPEG compression computations are mapped onto various resource-constrained platforms using a design environment that allows computation using the minimum integer and fractional bit-widths needed in view of other approximations inherent in the compression process and choice of image quality parameters. Advanced applications of JPEG, such as region of interest coding and successive/progressive transmission, are also examined. Detailed experimental results examining the tradeoffs in processor resources, processing/transmission time, bandwidth utilization, image quality, and overall energy consumption are presented.
