Acceptability and feasibility of a messenger-based psychological chat counselling service for children and young adults ("krisenchat"): A cross-sectional study.

Background: Adolescence represents a vulnerable period to experience personal crises or mental health problems. However, many concerns stay unnoticed due to the hesitance of young people to seek help and the unavailability and inaccessibility of appropriate help services. Contemporary interventions have been developed incorporating with target group specific needs and preferred modes of communication.

End expiratory oxygen concentrations to predict central venous oxygen saturation: an observational pilot study.

Background: A non-invasive surrogate measurement for central venous oxygen saturation (ScVO2) would be useful in the ED for assessing therapeutic interventions in critically ill patients. We hypothesized that either linear or nonlinear mathematical manipulation of the partial pressure of oxygen in breath at end expiration (EtO2) would accurately predict ScVO2.

Methods: Prospective observational study of a convenience sample of hemodialysis patients age > 17 years with existing upper extremity central venous catheters were enrolled.

Manganese(I) poly(mercaptoimidazolyl)borate complexes: spectroscopic and structural characterization of Mn...H-B interactions in solution and in the solid state.

The manganese(I) tricarbonyl complexes (Bm(R))Mn(CO)3(R = Me, Bz, But, p-Tol) and (PhBmMe)Mn(CO)3, the first bis(mercaptoimidazolyl)borate derivatives for this metal, have been readily prepared and fully characterized. In particular, the presence of three-center-two-electron Mn..

Dose comparison of tropisetron (Navoban) 5 mg and 10 mg orally in the prophylaxis of dacarbazine-induced nausea and emesis.

In this double-blind, randomized trial performed at five study centers, the prophylactic, antiemetic effect of two different dosages of tropisetron (Navoban; Sandoz Pharma Ltd, Basel, Switzerland) was investigated in dacarbazine-treated patients with melanoma. Patients received tropisetron 5 mg or 10 mg orally (as one capsule) once daily (minimum 3 days) on each day of chemotherapy. No significant differences were found in the effects of tropisetron 5 mg and 10 mg.
