A 52-year-old man suffering from Behçet's disease had undergone 6 operations for recurrent aneurysms of the bilateral iliac and femoral arteries. Thereafter, the patient underwent graft replacement for abdominal aortic aneurysm. Six years later he complained of lower abdominal pain and back pain. Abdominal CT-scan revealed abnormality of the proximal anastomotic site. The proximal suture line was completely dehiscent. The distal edge of infra-renal abdominal aorta was closed with interrupted mattress sutures. A right axillo-iliac bypass using a Dacron graft was performed for arterial reconstruction of the lower extremity. The patient has been free of recurrence for 4 years after the operation.

Six 1-month-old piglets were intravenously injected with deoxynivalenol (DON) at the concentration of 1 mg/kg body weight, with three pigs each necropsied at 6 and 24 h post-injection (PI) for investigation of hepatotoxicity and immunotoxicity with special attention to apoptotic changes and cytokine mRNA expression. Histopathological examination of the DON-injected pigs revealed systemic apoptosis of lymphocytes in lymphoid tissues and hepatocytes. Apoptosis of lymphocytes and hepatocytes was confirmed by the TdT-mediated dUTP-biotin nick end-labeling (TUNEL) method and immunohistochemical staining against single-stranded DNA and cleaved caspase-3. The number of TUNEL-positive cells in the thymus and Peyer's patches of the ileum was increased at 24 h PI compared to 6 h PI, but the peak was at 6 h PI in the liver. The mRNA expression of interleukin (IL)-1beta, IL-6, IL-18, and tumor necrosis factor (TNF)-alpha in the spleen, thymus and mesenteric lymph nodes were determined by semi-quantitative RT-PCR, and elevated expression of IL-1beta mRNA at 6 h PI and a decrease of IL-18 mRNA at 24 h PI were observed in the spleen. IL-1beta and IL-6 mRNA expressions increased significantly at 6 h PI in the thymus, but TNF-alpha decreased at 6 h PI in the mesenteric lymph nodes. These results show the apoptosis of hepatocytes suggesting the hepatotoxic potential of DON, in addition to an immunotoxic effect on the modulation of proinflammatory cytokine genes in lymphoid organs with extensive apoptosis of lymphocytes induced by acute exposure to DON in pigs.

BACKGROUND/OBJECTIVES: Alzheimer's disease is a neurodegenerative disease that induces symptoms such as a decrease in motor function and cognitive impairment. Increases in the aggregation and deposition of amyloid beta protein (Aβ) in the brain may be closely correlated with the development of Alzheimer's disease. In this study, the effects of an adzuki bean extract on the aggregation of Aβ were examined; moreover, the anti-Alzheimer's activity of the adzuki extract was examined. MATERIALS/METHODS: First, we undertook thioflavin T (ThT) fluorescence analysis and transmission electron microscopy (TEM) to evaluate the effect of an adzuki bean extract on Aβ42 aggregation. To evaluate the effects of the adzuki extract on the symptoms of Alzheimer's disease in vivo, Aβ42-overexpressing Drosophila were used. In these flies, overexpression of Aβ42 induced the formation of Aβ42 aggregates in the brain, decreased motor function, and resulted in cognitive impairment. RESULTS: Based on the results obtained by ThT fluorescence assays and TEM, the adzuki bean extract inhibited the formation of Aβ42 aggregates in a concentration-dependent manner. When Aβ42-overexpressing flies were fed regular medium containing adzuki extract, the Aβ42 level in the brain was significantly lower than that in the group fed regular medium only. Furthermore, suppression of the decrease in motor function, suppression of cognitive impairment, and improvement in lifespan were observed in Aβ42-overexpressing flies fed regular medium with adzuki extract. CONCLUSIONS: The results reveal the delaying effects of an adzuki bean extract on the progression of Alzheimer's disease and provide useful information for identifying novel prevention treatments for Alzheimer's disease.

Aims: This study aimed at investigating the status of polypharmacy and the experience and perception of bereaved family members of patients with advanced cancer regarding the burden of oral medication. Methods: Self-administered questionnaires were mailed to 303 bereaved family members of patients with advanced cancer, and 102 valid responses were analyzed (response rate, 33.7%). Results: The number of patients in the polypharmacy group (patients taking six or more tablets at a time) was 65 and that in the non-polypharmacy group (patients taking less than six tablets at a time) was 37. The percentage of bereaved family members who felt that the oral administration burden of patients was significantly higher in the polypharmacy group (43.1% vs. 10.8%, p<0.01). The results of the analysis indicated that the bereaved families wanted to reduce the number of tablets taken at a time for alleviating the burden of polypharmacy. The bereaved families of patients in the polypharmacy group were greatly concerned that the number of oral medications was too large. They also expressed the need for medical staff from whom they could seek explanation and counseling regarding the oral medication of patients. Conclusion: It is suggested that medical staff need to be fully aware of the concerns of patients’ families regarding drugs besides checking the compliance status.

OBJECTIVE:
This study estimated the effects of weekend and off-hour childbirth and the size of perinatal medical care center on the incidence of cerebral palsy.
METHODS:
The cases were all children with severe cerebral palsy born in Japan from 2009 to 2012 whose data were stored at the Japan Obstetric Compensation System for Cerebral Palsy database, a nationally representative database. The inclusion criteria were the following: neonates born between January 2009 and December 2012 who had a birth weight of at least 2000 g and gestational age of at least 33 weeks and who had severe disability resulting from cerebral palsy independent of congenital causes or factors during the neonatal period or thereafter. Study participants were restricted to singletons and controls without report of death, scheduled cesarean section, or ambulance transportation. The controls were newborns, randomly selected by year and type of delivery (normal spontaneous delivery without cesarean section and emergency cesarean section) using a 1:10 case to control ratio sampled from the nationwide Japan Society of Obstetrics and Gynecology database.
RESULTS:
A total of 90 cerebral palsy cases and 900 controls having normal spontaneous delivery without cesarean section were selected, as were 92 cerebral palsy cases and 920 controls with emergent cesarean section. A significantly higher risk for cerebral palsy was found among cases that underwent emergent cesarean section on weekends (odds ratio [OR] 1.72, 95% confidence interval [CI] 1.06-2.81) and during the night shift (OR 2.29, 95% CI 1.30-4.02). No significant risk was found among normal spontaneous deliveries on weekends (OR 1.63, 95% CI 0.97-2.73) or during the quasi-night shift (OR 1.26, 95% CI 0.70-2.27). Regional perinatal care centers showed significantly higher risk for cerebral palsy in both emergent cesarean section (OR 2.35, 95% CI 1.47-3.77) and normal spontaneous delivery (OR 2.92, 95% CI 1.76-4.84).
CONCLUSION
Labor on weekends, during the night shift, and at regional perinatal medical care centers was associated with significantly elevated risk for cerebral palsy in emergency cesarean section.
