Purpose: Urinary catheterization is a common technique in clinical practice. There is, however, no consensus on management prior to removal of the indwelling catheter for short-term patients. This systematic review examined the necessity of clamping before removal of an indwelling urinary catheter in short-term patients. Methods: A systematic literature review was conducted using eight databases and predetermined keywords-guided searches. Some 2,515 studies were evaluated. Ten studies that met the inclusion criteria were selected. Results: The quality of the studies was assessed using the Jadad scoring system. Only 40.0% of studies were rated as high quality. This review found that catheter clamping prior to removal was not necessary for the short-term patient. When made a comparison with the unclamping group, there was no significant difference in recatheterization risk, risk of urine retention, patients’ subjective perceptions and rate of urinary tract infection. Conclusions: This review indicated that bladder training by clamping prior to removal of urinary catheters is not necessary in short-term catheter patients. In addition, clamping carries the risk of complications such as prolonging urinary catheter retention and urinary tract injury. Further investigation requires higher quality methodologies and more diverse study designs.

Abstract We report the case of a 16-year-old male patientpresenting with several mass lesions on the left side of hisneck that had been there for weeks. Whole-body 18Ffluorodeoxyglucosepositron emission tomography and computedtomography (18F FDGPET-CT) revealedmultiple focalareas of increased uptake of fluorodeoxyglucose (FDG) on theleft side of the neck, left supraclavicular fossa, left axilla, andmediastinum, simulating the imaging findings of Hodgkin’slymphoma. Subsequent incisional biopsy of lymph nodes inthe left supraclavicular fossa with histologic examination confirmedthe diagnosis of Kimura disease. The differential diagnosesshould include Kimura disease when evaluating regionalor generalized lymphadenopathy seen on 18F FDGPET-CTbecause it also may show prominent uptake of FDG.

Lactobacillus (Lab.) is a human probiotic beneficial for the prevention and improvement of disease, yet properties of different Lab. strains are diverse. To obtain a Lab. strain that possesses greater potential against gastrointestinal dysfunction, we isolated Lactobacillus plantarum TCI378 (TCI378) from naturally fermented Korean kimchi. TCI378 has shown potential as probiotic since it can survive at pH 3.0 and in the presence of 0.3% bile acid. The bile salt hydrolase activity of TCI378 was shown by formation of opaque granular white colonies on solid de Man Rogosa Sharpe (MRS) medium supplemented with taurodeoxycholic acid, and its cholesterol-lowering ability in MRS medium supplemented with cholesterol. The metabolites of TCI378 from liquid culture in MRS medium prevented emulsification of bile salts. Moreover, both the metabolites of TCI378 and the dead bacteria reduced oil droplet accumulation in 3T3-L1, as detected by Oil red O staining. The expressions of adipocyte-specific genes perilipin 1 and glucose transporter type 4 were suppressed by the metabolites of TCI378, indicating TCI378 may have anti-obesity effects in adipocytes. These in vitro data show the potential of the prophylactic applications of TCI378 and its metabolites for reducing fat and lowering cholesterol.

Interleukin (IL)-20, a proinflammatory cytokine of the IL-10 family, is involved in acute and chronic renal failure. The aim of this study was to elucidate the role of IL-20 during diabetic nephropathy development. We found that IL-20 and its receptor IL-20R1 were upregulated in the kidneys of mice and rats with STZ-induced diabetes. In vitro, IL-20 induced MMP-9, MCP-1, TGF-β1 and VEGF expression in podocytes. IL-20 was upregulated by hydrogen peroxide, high-dose glucose and TGF-β1. In addition, IL-20 induced apoptosis in podocytes by activating caspase-8. In STZ-induced early diabetic nephropathy, IL-20R1-deficient mice had lower blood glucose and serum BUN levels and a smaller glomerular area than did wild-type controls. Anti-IL-20 monoclonal antibody (7E) treatment reduced blood glucose and the glomerular area and improved renal functions in mice in the early stage of STZ-induced diabetic nephropathy. ELISA showed that the serum IL-20 level was higher in patients with diabetes mellitus than in healthy controls. The findings of this study suggest that IL-20 induces cell apoptosis of podocytes and plays a role in the pathogenesis of early diabetic nephropathy.

Probable human carcinogenic compounds nitrosamines, have been detected as by-product impurities in sartan pharmaceuticals in recent years which has drawn worries for medication safety. To provide a sensitive and effective method for the quality control of sartan pharmaceuticals, this study established a feasible gas chromatography-tandem mass spectrometry (GC-MS/MS) method for simultaneous determination of 13 nitrosamines. The target analytes were separated on a DB-WAX Ultra Inert column (30 m × 0.25 mm; i.d., 0.25 μm) and were then subjected to electron impact ionization in multiple reaction monitoring mode. The established method was validated and further employed to analyze authentic samples. Limits of detection (LODs) and limits of quantification (LOQs) of the 13 nitrosamines were 15-250 ng/g and 50-250 ng/g, respectively, which also exhibited intra-day and inter-day accuracies of 91.4-104.8%, thereby satisfying validation criteria. Five nitrosamines, viz., Nnitrosodiethylamine, N-nitrosodimethylamine, N-nitrosodiphenylamine, N-nitrosomorpholine, and N-nitrosopiperidine were detected at concentrations above their LODs in 68 positive samples out of 594 authentic samples from seven sartans.

<P><B>Aims</B></P><P>Cardiac calsequestrin (CASQ2) and histidine-rich Ca-binding protein (HRC) are sarcoplasmic reticulum (SR) Ca-binding proteins that regulate SR Ca release in mammalian heart. Deletion of either CASQ2 or HRC results in relatively mild phenotypes characterized by preserved cardiac structure and function, although CASQ2 knockout (KO), or Cnull, shows increased arrhythmia burden under conditions of catecholaminergic stress. We hypothesized that given the apparent overlap of functions of CASQ2 and HRC, simultaneous ablation of both would deteriorate the cardiac phenotype compared with the single knockouts.</P><P><B>Methods and results</B></P><P>In contrast to this expectation, double knockout (DKO) mice lacking both CASQ2 and HRC exhibited normal cardiac ejection fraction and ultrastructure. Moreover, the predisposition to catecholamine-dependent arrhythmia that characterizes the Cnull phenotype was alleviated in the DKO mice. At the myocyte level, DKO mice displayed Ca transients of normal amplitude; additionally, the frequency of spontaneous Ca waves and sparks in the presence of isoproterenol were decreased markedly compared with Cnull. Furthermore, restitution of SR Ca release was slowed in DKO myocytes compared with Cnull cells.</P><P><B>Conclusion</B></P><P>Our results suggest that rather than being functionally redundant, CASQ2 and HRC modulate cardiac ryanodine receptor-mediated (RyR2) Ca release in an opposing manner. In particular, while CASQ2 stabilizes RyR2 rendering it refractory in the diastolic phase, HRC enhances RyR2 activity facilitating RyR2 recovery from refractoriness.</P>

In this study, the predatory efficacy of Orius strigicollis (Poppius), a predacious flower bug, against the twospotted spider mite (TSSM), Tetranychus urticae Koch, on strawberry (Fragaria ananassa) was investigated. Our results showed that release of 2, 4, 6, and 12 neonates of O. strigicollis per strawberry plant could suppress 58.9, 72.6, 88.6, and 92.8% of T. urticae, respectively, at 14 days after treatment. A single release of 12 neonate bugs per plant achieved and maintained, over a period of 3 months, 82% to 98% control of T. urticae population. A biweekly release of 6 neonate bugs per plant; likewise, suppressed ca. 90% of T. urticae population throughout the same period. However, predatory efficacy was reduced by an over-release of predators which may cause cannibalism as well as lower possibility of finding prey. Since the released neonates survived well to adults with offspring that retained their predatory ability, this study has demonstrated that O. strigicollis is a predatorwith good potential for sustainable suppression of T. urticae on strawberry, and one application of O. strigicollis neonates at a predator:prey ratio of 1:200 egg plus motile TSSM or 1:60 motiles per strawberry plant promises a season-long control and substantial management of spider mite infestation.
