BACKGROUND: Food restriction has been reported to ameliorate diabetes and obesity. In this study, we examined the effects of the food restriction on phenotypes of TALLYHO/JngJ (TH) mouse, a recently developed diabetic model animal. METHODS: 3 week-old TH mice were divided into 2 groups (n = 20 each for food-restricted (THR) and free-fed (THF)) and THR mice were fed the same amount of food as normal control mice (C57BL/6, n = 20). Body weight was weekly monitored till 14 weeks of age. The half of animals were sacrificed at 8 weeks of age, and liver, kidney, and fat weight were measured. The histopathology of liver and brown fat tissues and mRNA expression of leptin in adipose tissue were analyzed. The oral glucose tolerance test and insulin resistance test was done at 14 weeks of age. The plasma concentrations of glucose, free fatty acid, triglyceride, cholesterol and leptin were analyzed. RESULTS: The THR mice had lower body weights than the THF mice, similar to C57BL/6 mice, with reduced fat deposition in liver and brown fat tissue. The plasma levels of glucose, triglyceride and free fatty acid were decreased in the THR group. The THR mice, however, carried more fat than normal mice, with increased plasma leptin concentration and leptin mRNA expression in fats and no alteration in plasma cholesterol levels. Furthermore, the THR mice revealed glucose intolerance with impaired after-meal insulin secretion and slight insulin resistance CONCLUSION: The food restriction apparently ameliorated the obesity and diabetic phenotypes of TH mice. However, plasma concentration of cholesterol were not improved in THR mice with increased adiposity index and glucose intolerance, suggesting the genetically prone tendency of obesity and diabetes development in TH mice possibly with an impairment in cholesterol metabolism.

Cerebral infarction in cancer patients is often caused by thrombosis due to hypercoagulability, and in some cases, caused by direct tumor embolism. We report the case of cerebral infarction due to direct tumor embolism mixed with thrombus. Biopsy of blood clots obtained during thrombectomy is important for diagnosis. If there is a high risk of thrombosis among cancer patients with cerebral infarction, the use of appropriate antithrombotic agents along with maintaining a certain level of platelets should be considered.

Thyroid dysfunction is one of the more prevalent clinical situations encountered by primary care physicians. Thyroid storm is defined as a life-threatening exacerbation of the hyperthyroid state in which there is evidence of decompensation of one or more organ systems. Common precipitants include infection, surgery, diabetic ketoacidosis, vascular accidents, non-compliance with antithyroid medication, and emotional stress, but rarely develop in invasive molar pregnancy. An 18-year-old woman presented to the emergency department complaining of lower abdominal pain and vaginal spotting. She had no previous history of hyperthyroidism. Under the diagnosis of invasive molar pregnancy, dilatation and curettage was performed. However, right after the procedure the patient developed a semi-coma metal status, high grade fever, and tachycardia. Prompt diagnosis of thyroid storm was made and treatment followed immediately. We present a case of thyroid storm and a review of thyroid storm precipitated by invasive molar pregnancy.

The aim of this study was to evaluate the relationship between coronary artery calcium score (CACS) assessed by multidetector computed tomography (MDCT) and plaque components assessed by virtual histology-intravascular ultrasound (VH-IVUS) in 172 coronary artery disease (CAD) patients with 250 coronary lesions. CACS was assessed according to Agatston scoring method by MDCT and patients were divided into four groups: Group I (CACS = 0 [n = 52]); Group II (CACS = 1-100 [n = 99]); Group III (CACS = 101-400 [n = 84]); and Group IV (CACS > 400 [n = 15]). Total atheroma volume was greatest in Group IV (152 +/- 132 microL vs 171 +/- 114 microL vs 195 +/- 149 microL vs 321+/-182 microL, P < 0.001). The absolute dense calcium (DC) and necrotic core (NC) volumes were greatest, and relative DC volume was greatest in Group IV (5.5 +/- 6.6 microL vs 11.0 +/- 10.3 microL vs 15.6 +/- 13.6 microL vs 36.6 +/- 18.2 microL, P < 0.001, and 14.8 +/- 18.2 microL vs 19.5 +/- 18.9 microL vs 22.5 +/- 19.1 microL vs 41.7 +/- 27.9 microL, P < 0.001, and 6.4 +/- 5.3% vs 11.0 +/- 6.2% vs 14.0 +/- 6.5% vs 20.0 +/- 7.8%, P < 0.001, respectively). The absolute plaque and DC and NC volumes and the relative DC volume correlated positively with calcium score. CAD patients with high calcium score have more vulnerable plaque components (greater DC and NC-containing plaques) than those with low calcium score.

BACKGROUND/AIMS: It is well known that the menopause is related to interference in lipid metabolism, obesity, and a hypercoagulable state. The aim of the present study was to examine the impact of the menopause in middle-aged Korean females with acute myocardial infarction (AMI). METHODS: A total of 1,781 middle-aged females (aged < 65 years) in the Korean Acute Myocardial Infarction registry were enrolled into this study between November 2005 and December 2013. The patients were divided into two groups; the pre-menopause group (≤ 55 years old) and the menopause group (56-64 years old). Major adverse cardiac events (MACE) were analyzed over a one-year follow-up period. RESULTS: The pre-menopause and menopause groups comprised 669 patients (mean age, 49.1 ± 5.6 years) and 1,112 patients (mean age, 60.6 ± 2.6 years), respectively. The incidence of hypertension (42.2% vs. 59.4%, p < 0.001), diabetes mellitus (DM) (27.4% vs. 35.7%, p < 0.001), and dyslipidemia (12.9% vs. 17.7%, p = 0.008) were more frequent in menopausal patients. Additionally, the rates of smoking (20% vs. 12.7%, p < 0.001) and familial history (12% vs. 6.8%, p < 0.001) were higher in the pre-menopause group. The cumulative rates of MACE did not show any differences between the two groups. A history of atrial fibrillation, previous AMI and DM, higher Killip class, and multi-vessel disease were independent risk factors for predicting one-year MACE. CONCLUSIONS: The survival analysis demonstrated that there was no significant difference in MACE rates between the pre-menopause and menopause groups during the one-year follow-up. Therefore, middle-aged pre-menopausal women should be treated more intensively, regardless of whether they are menopausal.
