The behavioral pharmacology of olanzapine, a novel "atypical" antipsychotic agent.

Abstract: Olanzapine (LY170053, 2-methyl-4-(4-methyl-1-piperazinyl)-10H-thieno[2,3-b][1,5] benzodiazepine) is a novel "atypical" antipsychotic agent with 5-hydroxytryptamine2.dopamine D1/D2 antagonist activity and anticholinergic properties. In behavioral studies, olanzapine (1.25-10 mg/kg, p.o.) antagonizes apomorphine-induced climbing behavior in mice, demonstrating that the compound possesses D1/D2 antagonist activity in vivo. Olanzapine (0.3-20 mg/kg, p.o.) antagonizes 5-hydroxytryptophan-induced head twitches in mice at doses much lower than those required to block the climbing response, confirming that in vivo, the compound is a more potent 5-hydroxytryptamine2 antagonist than dopamine antagonist. Olanzapine (2.5-10 mg/kg, p.o.) also antagonized oxotremorine-induced tremor in mice. In a conditioned avoidance paradigm in rats, olanzapine inhibits the avoidance response with an ED50 of 4.7 mg/kg p.o; however, unlike other antipsychotic agents, catalepsy is only observed at much higher doses (ED50 39.4 mg/kg, p.o.). These data would suggest that the compound will be less likely to produce undesirable extrapyramidal symptoms. Unlike "typical" antipsychotics, olanzapine (1.25-5 mg/kg p.o.) increases responding during the conflict component of a modified Geller Seifter test, demonstrating that the compound may also possess anxiolytic activity. In another series of experiments, olanzapine (1.25 mg/kg, i.p.) produced clozapine-appropriate responding in a drug discrimination model in which animals had been trained to discriminate clozapine (5 mg/kg, i.p.) from vehicle. On the basis of these results, it would therefore be predicted that olanzapine will have an atypical profile and will be less likely to induce undesirable extrapyramidal symptoms than currently available drugs.

Quality of life in sarcopenia and frailty.

Abstract: The reduced muscle mass and impaired muscle performance that define sarcopenia in older individuals are associated with increased risk of physical limitation and a variety of chronic diseases. They may also contribute to clinical frailty. A gradual erosion of quality of life (QoL) has been evidenced in these individuals, although much of this research has been done using generic QoL instruments, particularly the SF-36, which may not be ideal in older populations with significant comorbidities. This review and report of an expert meeting presents the current definitions of these geriatric syndromes (sarcopenia and frailty). It then briefly summarizes QoL concepts and specificities in older populations and examines the relevant domains of QoL and what is known concerning QoL decline with these conditions. It calls for a clearer definition of the construct of disability, argues that a disease-specific QoL instrument for sarcopenia/frailty would be an asset for future research, and discusses whether there are available and validated components that could be used to this end and whether the psychometric properties of these instruments are sufficiently tested. It calls also for an approach using utility weighting to provide some cost estimates and suggests that a time trade-off study could be appropriate.

Therapy focused on lowering postprandial glucose, not fasting glucose, may be superior for lowering HbA1c. IOEZ Study Group.

Abstract: OBJECTIVE: To compare the overall efficacy of combination therapies focused on fasting or postprandial blood glucose in patients with type 2 diabetes not adequately controlled with oral sulfonylurea agents alone. RESEARCH DESIGN AND METHODS: A total of 135 patients were randomly assigned for 3 months to 1 of 3 combination regimens with glyburide (G) that addressed postprandial blood glucose with insulin lispro (L+G), premeal blood glucose with metformin (M+G), or fasting blood glucose (FBG) with bedtime NPH insulin (NPH+G). RESULTS: At end point, HbA1c was significantly lower with all therapies (P = 0.001) and was significantly lower for L+G (7.68+/-0.88%) compared with either NPH+G (8.51+/-1.38%, P = 0.003) or M+G (8.31+/-1.31%, P = 0.025). FBG at end point was significantly lower for NPH+G (8.49+/-2.36 mmol/l) compared with either L+G (10.57+/-1.97 mmol/l, P = 0.001) or M+G (9.69+/-2.89 mmol/l, P = 0.029). The mean 2-h postprandial glucose after a test meal was significantly lower for L+G (10.87+/-2.88 mmol/l) versus NPH+G (12.21+/-3.12 mmol/, P = 0.052) or versus M+G (12.72+/-3.26 mmol/l, P = 0.009). The overall rate of hypoglycemia (episodes per 30 days) was low and not statistically significant between groups (P = 0.156). CONCLUSIONS: Adding a second antihyperglycemic agent, regardless of its timing of action, lowers HbA1c and glucose values. However, when insulin lispro was used to focus on postprandial blood glucose, there was a greater impact on overall metabolic control. These data support the importance of lowering postprandial blood glucose to optimize overall glycemic control and thus improve long-term outcomes.

Hospitalized cancer patients with severe sepsis: analysis of incidence, mortality, and associated costs of care.

Abstract: Introduction Infection is an important complication in cancer patients, which frequently leads to or prolongs hospitalization, and can also lead to acute organ dysfunction (severe sepsis) and eventually death. While cancer patients are known to be at higher risk for infection and subsequent complications, there is no national estimate of the magnitude of this problem. Our objective was to identify cancer patients with severe sepsis and to project these numbers to national levels.
