Association between ANGPTL3, 4, and 8 and lipid and glucose metabolism markers in patients with diabetes.

Lipid management, especially with respect to triglyceride (TG) metabolism, in patients with diabetes is not sufficient with current therapeutic agents, and new approaches for improvement are needed. Members of the angiopoietin-like protein (ANGPTL) family, specifically ANGPTL3, 4, and 8, have been reported as factors that inhibit lipoprotein lipase (LPL) activity and affect TGs. The present study investigated the association between lipid and glucose metabolism markers and the mechanism by which these proteins affect lipid metabolism. A total of 84 patients hospitalized for diabetes treatment were evaluated. Lipid and glucose metabolism markers in blood samples collected before breakfast, on the day after hospitalization, were analyzed. ANGPTL8 showed a significant positive correlation with TG values. HDL-C values displayed a significant positive correlation with ANGPTL3 but a negative correlation with ANGPTL4 and ANGPTL8. The results did not indicate a significant correlation among ANGPTL3, 4, and 8 levels. Thus, it is possible that the distribution of these proteins differs among patients. When patients were divided into groups according to the levels of ANGPTL3 and ANGPTL8, those with high levels of both ANGPTL3 and ANGPTL8 also had high levels of TG and small dense LDL-C/LDL-C (%). Multiple regression analysis indicated that low LPL, high ApoC2, high ApoC3, high ApoE, and high ANGPTL8 levels were the determinants of fasting hypertriglyceridemia. By contrast, no clear association was observed between any of the ANGPTLs and glucose metabolism markers, but ANGPTL8 levels were positively correlated with the levels of HOMA2-IR and BMI. Patients with high levels of both ANGPTL3 and ANGPTL8 had the worst lipid profiles. Among ANGPTL3, 4, and 8, ANGPTL8 is more important as a factor determining plasma TG levels. We anticipate that the results of this research will facilitate potential treatments targeting ANGPTL8 in patients with diabetes.

Nivolumab-induced Vogt-Koyanagi-Harada-like Syndrome and Adrenocortical Insufficiency with Long-term Survival in a Patient with Non-small-cell Lung Cancer.

A 58-year-old man was diagnosed with lung adenocarcinoma with a tumor proportion score of 10%. After six cycles of second-line chemotherapy with nivolumab, he achieved a complete response (CR) but developed uveitis and sensorineural hearing disorder, which were consistent with Vogt-Koyanagi-Harada (VKH)-like syndrome. Simultaneously, pituitary adrenocortical insufficiency was identified. Nivolumab discontinuation and systemic corticosteroid administration resolved these immune-related adverse events (irAEs). The patient has maintained a CR without any chemotherapy for approximately two years. We herein report a patient with a long-term progression-free survival despite chemotherapy discontinuation due to irAEs, including VKH-like syndrome, which were appropriately managed.

[Multicenter surveillance of Pseudomonas aeruginosa strains for antimicrobials in Aichi prefecture in 2009].

We investigated the susceptibility to antimicrobials of 204 Pseudomonas aeruginosa strains isolated from 21 hospitals in Aichi prefecture from September to November 2009. MIC distributions of various antimicrobials were analyzed in terms of geographic region of isolation, patient status (outpatient or inpatient), and type of specimens that the strain was isolated from. The results were as follows. 1. Although more than 90% of strains were susceptible to all aminoglycosides and colistin, 80-90% of them were susceptible to beta-lactams and fluoroquinolones. MIC distributions of all antimicrobials measured were not significantly different between regions. 2. Only 1 strain (0.5%) was multi-drug resistant Pseudomonas aeruginosa (MDRP). Thirteen strains (6.4%) showed imipenem MIC > or = 16 microg/mL, and 16 strains (7.8%) showed ciprofloxacin MIC > or = 4 microg/mL. These strains tended to be more isolated from urine, respiratory tract specimens, or surgical specimens. 3. The MICs of tazobactam/piperacillin, panipenem, meropenem, doripenem, biapenem, sulbactam/cefoperazone, cefepime, and aztreonam were significantly higher in strains isolated from inpatients than in those from outpatients. MIC distributions of antimicrobials other than beta-lactams were not significantly different between situations where strains were isolated. 4. MIC distributions of piperacillin, all carbapenems, cefepime, gentamicin, and all fluoroquinolones were significantly different among samples from which strains were isolated. The strains isolated from blood showed lower MICs against all antimicrobials than those from other samples. No difference was found in MIC distributions when categorized according to bacteremic origin. The MICs were apparently elevated against beta-lactams, fluoroquinolones, and gentamicin in strains isolated from respiratory tract specimens, and against beta-lactams, and fluoroquinolones in strains isolated from urine. It was suggested that in P. aeruginosa surveillance, the results should be reported by stratifying with patient status, and type of specimens that the strain was isolated from and that regional surveillance should be useful with such stratification to establish antibiograms for empirical antimicrobial choice.

A novel proton conductor of imidazole-aluminium phosphate hybrids in the solid state.

Anhydrous proton transport at temperatures above 100 °C has attracted considerable attention in the development of fuel cells that operate at intermediate temperatures. Liquid-state imidazole (ImH) is known to be a fast anhydrous proton conductor above 100 °C; however, evaporation and severe conductivity drops above and below its melting point (∼90 °C), respectively, are major drawbacks to ImH. In this paper, we report a novel solid-state anhydrous ImH-Al(H(2)PO(4))(3) (AlP) hybrid material prepared via a simple synthesis using mechanical milling. This solid-state hybrid exhibits relatively a high ionic conductivity of ∼0.1 mS cm(-1) at 100 °C and remarkably a small activation energy of 0.23 eV. In addition, the ImH-AlP hybrid material provides a means of overcoming both temperature-dependent drawbacks to pure ImH: (1) the ImH-AlP hybrid is thermally stable up to 130 °C, and (2) the hybrid material maintains high ionic conductivity below the melting point of ImH.

[Etiological bacterial level in enterohemorrhagic Escherichia coli infection feces and chromogenic culture medium CHROMagar STEC usefulness].

We report a case of enterohemorrhagic Escherichia coli (EHEC) infection in which EHEC was not detected by culture on DHL agar medium. The proportion of EHEC bacterial count to enterobacterial count in feces was 1.7%, and the detection probability by 5-colony angling was low (8.1%). The probability of angling detection using CHROMagar STEC, a chromogenic medium for detecting EHEC, was high (100%). An additional and collection test was done using E. coli bacterial solutions to which two main sera groups--O157 and O26 were added. The maximum detectable level in the bacterial solution with O157 was 10(3)-10(4) CFU/mL in DHL and 10(2) CFU/mL in CHROMagar STEC. Bacterial solution levels with O26 were 10(3) CFU/mL in DHL and 10(2) CFU/mL in CHROMagar STEC. Assuming that the EHEC bacterial amount in feces of those with EHEC infection is low, we speculated that CHROMagar STEC may be useful as on EHEC screening medium.
