There are limited data on the impact of diabetes control on the risk of subclinical coronary atherosclerosis.

4-hydroxy-3-methoxycinnamic acid (ferulic acid, FA) is known to have numerous beneficial health effects, including anti-obesity and anti-hyperglycemic properties. However, the molecular networks that modulate the beneficial FA-induced metabolic effects have not been well elucidated. In this study, we explored the molecular mechanisms mediating the beneficial metabolic effects of FA. In mice, FA protected against high-fat diet-induced weight gain, reduced food intake and exhibited an overall improved metabolic phenotype. The food intake suppression by FA was accompanied by a specific reduction in hypothalamic orexigenic neuropeptides, including agouti-related protein and neuropeptide Y, with no significant changes in the anorexigenic peptides pro-opiomelanocortin and cocaine and amphetamine-regulated transcript. FA treatment also inhibited fat accumulation in the liver and white adipose tissue and suppressed the expression of gluconeogenic genes, including phosphoenolpyruvate carboxylase and glucose-6-phosphatase. Furthermore, we show that FA phosphorylated and inactivated the transcription factor FoxO1, which positively regulates the expression of gluconeogenic and orexigenic genes, providing evidence that FA might exert its beneficial metabolic effects through inhibition of FoxO1 function in the periphery and the hypothalamus.

BACKGROUND: Abacavir is a widely-used nucleoside reverse transcriptase inhibitor for the treatment of human immunodeficiency virus (HIV) infection. Mandatory postmarketing surveillance was conducted in Korea to monitor the safety and evaluate the effectiveness of Ziagen® (abacavir sulfate 300 mg; ViiV Healthcare, Middlesex, UK). MATERIALS AND METHODS: An open-label, multi-center, non-interventional postmarketing surveillance study was conducted from June 2010 to June 2016 to monitor the safety and effectiveness of Ziagen across 12 hospitals in Korea. Subjects older than 18 years taking Ziagen according to prescribing information were enrolled. The primary outcome was defined as the occurrence of any adverse events after Ziagen administration. Secondary outcomes included the occurrence of adverse drug reactions, occurrence of serious adverse events, and effectiveness of Ziagen administration. RESULTS: A total of 669 patients were enrolled in this study, with a total observation period of 1047.8 person-years. Of these, 90.7% of patients were male. The mean age of patients was 45.8±11.9 years. One-hundred ninety-six (29.3%) patients reported 315 adverse events, and four patients reported seven serious adverse events, without any fatal events. There was one potential case of an abacavir hypersensitivity reaction. Among the 97 adverse drug reactions that were reported from 75 patients, the most frequent adverse drug reactions included diarrhea (12 events), dyspepsia (10 events), and rash (9 events). No ischemic heart disease was observed. In the effectiveness analysis, 91% of patients achieved HIV-1 RNA under 50 copies/mL after 24 months of observation with abacavir administration. CONCLUSION: Our data showed the safety and effectiveness of Ziagen in a real-world setting. During the study period, Ziagen was well-tolerated, with one incident of a clinically suspected abacavir hypersensitivity reaction. The postmarketing surveillance of Ziagen did not highlight any new safety information. These data may be helpful in understanding abacavir and the HIV treatment practices in Korea.

An iliopsoas abscess is a collection of pus in the iliopsoas muscle caused by the direct spread of infection from adjacent internal organs or by hematogenous or lymphatic spread from distal sites. Its symptoms are vague back, hip, thigh or lower abdomen pain with insidious onset, similar to those of ankylosing spondylitis (AS). Therefore diagnosing an iliopsoas abscess in patients with AS is difficult. A forty-three year-old man was treated with adalimumab, a tumor necrosis factor inhibitor, and clinical symptoms were subsequently observed to improve. One year after voluntary discontinuation of adalimumab, the patient returned with a recurrence of right buttock pain and was diagnosed as having aggravated AS. Following re-initiation of adalimumab, symptoms did not improve and fever developed. On the basis of imaging studies, the patient was diagnosed as having an iliopsoas abscess and was successfully treated with intravenous antibiotics.

BACKGROUND: The increasing prevalence of type 2 diabetes mellitus (T2DM) is associated with the rapid spread of obesity. Obesity induces insulin resistance, resulting in beta-cell dysfunction and thus T2DM. Green tea extract (GTE) has been known to prevent obesity and T2DM, but this effect is still being debated. Our previous results suggested that circulating green tea gallated catechins (GCs) hinders postprandial blood glucose lowering, regardless of reducing glucose and cholesterol absorption when GCs are present in the intestinal lumen. This study aimed to compare the effect of GTE with that of GTE coadministered with poly-gamma-glutamic acid (gamma-PGA), which is likely to inhibit the intestinal absorption of GCs. METHODS: The db/db mice and age-matched nondiabetic mice were provided with normal chow diet containing GTE (1%), gamma-PGA (0.1%), or GTE+gamma-PGA (1%:0.1%) for 4 weeks. RESULTS: In nondiabetic mice, none of the drugs showed any effects after 4 weeks. In db/db mice, however, weight gain and body fat gain were significantly reduced in the GTE+gamma-PGA group compared to nondrug-treated db/db control mice without the corresponding changes in food intake and appetite. Glucose intolerance was also ameliorated in the GTE+gamma-PGA group. Histopathological analyses showed that GTE+gamma-PGA-treated db/db mice had a significantly reduced incidence of fatty liver and decreased pancreatic islet size. Neither GTE nor gamma-PGA treatment showed any significant results. CONCLUSION: These results suggest that GTE+gamma-PGA treatment than GTE or gamma-PGA alone may be a useful tool for preventing both obesity and obesity-induced T2DM.

PURPOSE: To investigate the significance of the cortex-hilum (CH) area ratio and longitudinal-transverse (LT) axis ratio and the blood flow pattern for diagnosis of metastatic axillary lymph nodes by ultrasound in breast cancer patients. METHODS: From October 2005 to July 2006, we prospectively evaluated axillary nodes with ultrasound in 205 consecutive patients who had category 4B, 4C or 5 breast lesions according to the Breast Imaging Reporting and Data System-Ultrasound (BI-RADS-Ultrasound(R)). Among the 205, there were 24 patients who had pathologic verification of breast cancer and axillary lymph node status. For a total of 80 axillary nodes we measured the areas of the cortex and hilum of lymph nodes and calculated the area ratio. We also measured the length of the longitudinal and transverse axis of the lymph nodes and calculated the length ratio. We evaluated the blood flow pattern on power Doppler imaging and classified each lymph node into a central or peripheral pattern. Diagnostic performance was analyzed according to positive criteria for lymph node metastasis (CH area ratio >2, LT axis ratio <2, peripheral type on power Doppler imaging). RESULTS: The sensitivity of the CH area ratio was superior to that of the LT axis ratio (94.1% vs. 82.3%, p=0.031) and to that of the blood flow pattern (94.1% vs. 29.4%, p=0.009). For specificity, all three evaluating parameters had high values (89.1-95.6%) and no significant differences were found (p=0.121). The CH area ratio had a better positive predictive value than the LT axis ratio (94.1% vs. 80.0%, p=0.030) and power Doppler imaging (94.1% vs. 66.6%, p=0.028). For the negative predictive value, the CH area ratio was superior to the LT axis ratio (95.6% vs. 86.6%, p=0.035) and the blood flow pattern (95.6% vs. 63.0%, p=0.027). CONCLUSION: We recommend the CH area ratio of an axillary lymph node on ultrasound as a quantitative indicator for the classification of lymph nodes. The CH area ratio can improve diagnostic performance when compared with the LT axis ratio or blood flow pattern.

OBJECTIVE: Ultrasound-guided needle localization has been used prior to the surgical excision of nonpalpable breast lesions. The aim of the study was to assess the feasibility of the use of a saline immersion specimen ultrasound technique (immersion-US) to confirm the successful removal of breast lesions. MATERIALS AND METHODS: The devised immersion-US technique was used to examine the excised tissues of 72 ultrasound-guided needle localized breast lesions of 58 patients (34 benign lesions, 30 high-risk lesions and 8 malignant lesions). Freshly excised specimens were placed in a container filled with saline and one radiologist scanned the surgically excised specimens using a high-frequency linear transducer. We evaluated successful lesion removal and the qualities of the immersion-US images. Miss rates were determined by the use of postoperative ultrasound during follow-up. RESULTS: All 72 lesions were identified by the use of immersion-US and satisfactory or excellent quality images were obtained for most lesions (70/72, 97%). Five (7%) lesions were initially identified as incompletely excised, based on the immersion-US findings, and prompt re-excision was undertaken. Follow-up ultrasound examinations showed no residual mass in the surgical field in any patient. CONCLUSION: The immersion-US technique was found straightforward and efficient to perform. Immersion-US was able to determine whether nonpalpable breast lesions had been successfully excised after ultrasound-guided needle localization.

BACKGROUND: The mortality of liver abscess has remained relatively constant during this century despite earlier diagnosis, treatment of underlying causes and more aggressive antibiotics therapy. The aims of this study were to evaluate the risk factors that associated with mortality of liver abscess. METHODS: This study was carried out retrospectively including 70 patients with liver abscess from January 1992 to August 2001. The clinical features, laboratory, imaging, and microbiologic findings, management strategy, and final outcome were studied, and prognostic factors were analyzed. RESULTS: There were 37 males and 33 females whose ages ranged from 17 to 89 years. The mean age of the patients was 57 years, and the male to female ratio was 1.1:1. In the major part of patients, the abscess was located in the right lobe (61.4%) and single in number (78.5%). Upper abdominal pain, fever and chills were the most common symptoms, and right upper abdominal tenderness was the most common physical findings. Twenty-six percent of patients were diabetic and 40%, 10% had biliary tract disease, malignancy on presentation, respectively.

A series of 61 cases of primary hemifacial spasm have been evaluated by means of blink reflex and needle electromyography and their result compared with unaffected site. The R1 and R2 response and late acti-ity. After activity in blink reflex. And electrical activity in EMG at rest were observed. The results of study were as in the followings: 1) The arnplitude of large R1 and R2 responses were increased in affected side in contrast to unaffected side. 2) late activity(72.2%) and after activity(83.6%) were observed in only affected side at rela-ti-ely Iong duration, as well as regular interval spontaneous repetivive discharges in EMG at rest. This result of large R1 and R2 responses could be compatible with ephaptic ransmission, but late activity, after activity, and spontaneous repetitive MUPs could be explained hyperexcitability of the facial motor nucleus rather than autoexcitation of peripheral facial nerve. Additionally the authors thought that the use of conventional blink reflex as well as specialized blink reflex tests could be very useful for the diagnosis of hemifacial spasm and for the evaluation of it's course.
