The aim of this study was to examine the effect of phase I cardiac rehabilitation program (CRP) on physical capacity in patients with coronary artery bypass graft (CABG). Eighty seven patients who underwent CABG in our hospital were enrolled on the study. Among them, excluding 17 during the study, the results of 70 patients were included in the final data. Subjects were classified into two groups according to the participation in the phase I CRP; participation group (n=35) and non-participation group (n=35). The CR was executed for the participation group until patients' discharge. The variables including resting heart rate (RHR), oxygen saturation, walking distance in 6 minutes, and forced expiration amount were measured at initial phase, discharge and follow-up at 1 month after discharge. From the data, descriptive statistics (mean, standard deviation) were calculated, and differences in each variable before, during, after the treatment and between groups were tested using repeated measure analysis of variance using SPSS ver. 18.0 statistics program for Window. For the effects and results with a statistical significance, post-hoc test was made using t-test. There was statistically significant difference (p<0.05) in the RHR and the walking distance in 6 minutes. While there was no significant difference in the oxygen saturation and the maximum expiration amount. As conclusion, the Phase I CRP after CABG showed a effect on the significant improvement of physical capacity by decreasing the RHR and increasing the walking distance in 6 minutes, exerting a positive influence on the recovery after the CABG operation.

Therapeutic irradiation can induce angiosarcoma. Radiation-induced angiosarcoma constitutes 20% of all angiosarcomas. Although its common site of origin is the skin and subcutaneous tissue, it rarely arises in small or large bowels with a presentation as multifocal abdominal angiosarcomatosis. We report a case of intra-abdominal angiosarcomatosis involving the jejunum, ileum, transverse colon, mesentery and right ovary in a 63-year-old female. It developed 10 years after therapeutic irradiation for squamous cell carcinoma of uterine cervix. She developed panperitonitis due to intestinal perforation. She died from sepsis 3 days after segmental resection of the small bowel and right oophorectomy. We reviewed the previously reported cases and describe the clinicopathologic features of this tumor.

PURPOSE: To report a case of delayed-onset expulsive suprachoroidal hemorrhage due to trauma after removal of a penetrating keratoplasty suture. CASE SUMMARY: A 66-year-old man had penetrating keratoplasty for bullous keratopathy performed in his left eye. After 1 year, the continuous suture was removed for adjustment of astigmatism. Four days after removal of the suture, the patient struck his left eye with the back of his hand, although at the time of injury he had no specific symptoms. Two days later, the patient noticed abrupt pain, decreased visual acuity, and massive hemorrhage in his left eye. Examination revealed an inferior wound dehiscence of approximately 8 clock hours (2 thru 10 o'clock) with prolapsed intraocular contents such as the uvea and retina. The patient underwent cornea graft resuturing with resection of ocular contents, which could not be repositioned. Although bleeding was controlled after the operation, vision was lost in his left eye. After two months, according to decrement of intraocular hematoma, the patient had a phthisis bulbi with low intraocular pressure in his left eye. CONCLUSIONS: Persistent low intraocular pressure due to wound leakage through the graft-host junction likely resulted in delayed onset of expulsive suprachoroidal hemorrhage. The risk of traumatic corneal graft rupture after penetrating keratoplasty is significant and is associated with a poor visual outcome and eyeball viability. Therefore, patients should be cautioned. In addition, the importance of eye examination after trauma should be emphasized.

Purpose: This study used an animal model to examine the effects of environmental enrichment (EE) and caloric restriction (CR) on hippocampal changes in early adulthood in a rat model. Methods: Male Sprague-Dawley rats were randomly assigned to control, EE, and CR groups. After 8 weeks of EE and CR, behavioral, biochemical, and molecular biological assessments were performed. Behavioral tests included the open field test for anxiety-like behavior, the eight-arm radial maze test for spatial learning, and the passive avoidance test for short-term memory. Glucose tolerance was assessed with an intraperitoneal glucose tolerance test, and the molecular markers associated with neuroinflammation were evaluated. Results: Both EE and CR reduced anxiety-like behaviors, as evidenced by increased time in the central region of the open field test and decreased rearing. However, neither EE nor CR significantly improved short-term memory or spatial learning. Nonetheless, the CR group showed a decrease in eight-arm radial maze completion time, indicating potential for enhanced learning. Both interventions improved glucose tolerance, with lower fasting blood glucose levels in the CR and EE groups. Molecular biological analyses showed that neuroinflammatory markers interleukin-6 and inducible nitric oxide synthase were reduced in the EE and CR groups and that Iba-1 had anti-inflammatory effects due to its neuroprotective action. Conclusion EE and CR were beneficial for emotional and metabolic health in early adult rats due to reductions in anxiety-like behaviors and neuroinflammation with a concomitant improvement in glucose metabolism. However, the effects of these modalities on improving cognitive function were limited, illustrating the need for further research.
