“Clostridium difficile infection

is a common cause of antibiotic-associated diarrhea. It causes no symptoms in more than One-half of infected patients, but can also cause a wide spectrum of illnesses and death. The incidence and severity. have increased in recent years. The most important modifiable risk factor for C. difficile infection is antibiotic exposure; this risk is dose-related and higher with longer courses and combination therapy. C. difficile infection is also associated with older age, recent hospitalization, multiple comorbidities, use of gastric acid blockers, inflammatory bowel CX-6258 mouse disease, and immunosuppression. It has become more common in younger, healthier patients in community settings. The most practical testing options are rapid testing with nucleic acid amplification or enzyme immunoassays to detect

toxin, or a two-step strategy Treatment includes discontinuing the contributing antibiotic, if possible. Mild C. difficile infection should be treated with oral metronidazole; severe infection should be treated with oral vancomycin. Fidaxomicin may be an effective alternative. Recurrences of the infection should be treated based on severity. Tapering and the pulsed-dose method of oral vancomycin therapy for second recurrences are effective. Prevention includes responsible antibiotic prescribing and vigilant handwashing. Probiotics prevent antibiotic-associated diarrhea, but are not recommended specifically for preventing C. difficile https://www.selleckchem.com/products/cbl0137-cbl-0137.html infection.

“The purpose of this study was to investigate dendritic glycerol-based amphiphiles as novel solubilizers using poorly water-soluble anticancer drug Sagopilone. The effect of different core structures on the solubilization, formulation GSK1210151A ic50 stability, and cytotoxicity using human umbilical vein endothelial cells (HUVECs) were investigated and compared to standard excipients. Structurally, all amphiphiles were composed of 2nd generation polyglycerol (PG[G2]) as the

hydrophilic part and a single C(18)-chain (PG[G2]-C(18)), a C(18)-chain coupled by a diaromatic spacer (PG[G2]-DiAr-C(18)), a C(18)-chain with a naphthyl or bisphenyl end group (PG[G2]-C(18)-Naph/-BiP), or two C(18)-chains (PG[G2]-(C(18)) as the hydrophobic part. They formed small (7-10 nm), monodisperse (PDI 0.04-0.20) micelles with the exception of PG[G2]-(C(18))(2). The amphiphiles revealed a 2-3-fold higher solubilization of Sagopilone than Cremophor (R) ELP and polysorbate 80 independent of the core structure. PG[G2]-DiAr-C(18) exhibited the highest solubilization capacity (56.7 +/- 1.3 mg/g) compared to Cremophor (R) ELP (18.5 +/- 0.1 mg/g). The micellar dispersions were stable in drug content over 3 days (>= 97%).
