10,000 reasons to step out--exercise patterns and pedometer evaluation of consultant anaesthetists.

Major international bodies recommend that adults should accumulate at least 30 minutes of moderate intensity physical activity every day. Ten thousand steps a day has been found to approximate 30 minutes of exercise. A questionnaire regarding exercise patterns was sent to all (584) Victorian consultant anaesthetists, and 30 consultants wore a pedometer for one week, during working hours only. The questionnaire response rate was 59.4% (347). Of these respondents, 58% indicated that they had a formal exercise program. There were no significant differences between people with a set exercise program and those without, with respect to age, gender, working hours or smoking. Those with a set exercise program exercised a median of four times per week and the commonest exercise listed was gymnasium attendance (40%). The main reasons cited for having a regular exercise program were maintenance of physical health (77%), mental health (71%) and weight control (35%). The main reasons for not having an exercise program were fatigue (40%), too busy (70%), family commitments (67%) or just not interested (18%). The overall median steps per day for the pedometer group was 4770 with a range of 1667 to 9630, fitting into the classification of 'sedentary'. In summary this study has shown that a significant number of anaesthetists do not achieve adequate physical activity in or out of working hours and has identified some reasons for this behaviour. This will hopefully provide motivation and information for the implementation of useful strategies to increase the level of physical activity performed by anaesthetists.

Free-operant performance on variable interval schedules with a linear feedback loop: no evidence for molar sensitivities in rats.

Four experiments examined rats' sensitivity to molar and molecular factors on instrumental schedules of reinforcement. Rats were exposed to a variable interval schedule with a positive feedback loop (VI+), such that faster responding led to a shorter interreinforcement interval. In Experiments 1 and 2, rats responded faster on a variable response (VR) schedule than on either a VI schedule matched for reinforcement rate or a VI+ schedule matched for the feedback function. In Experiment 3, rats responded no differently on a VI schedule than they did on a VI+ schedule with equated rates of reinforcement. In Experiment 4, rats responded faster on a VI+ schedule with an interresponse time requirement yoked to that experienced on a VR schedule, than on a VI+ schedule with the same feedback function as the VR schedule. Taken together these results suggest that rats are more sensitive to the molecular than the molar properties of the schedules.

[Continuous arterial infusion chemotherapy in cancer cases followed as outpatients].

Continuous arterial infusion chemotherapy is associated with a significantly greater tumor response rate, though patients must be hospitalized for a long time. This paper describes techniques and our experience with arterial continuous infusion chemotherapy for outpatients using implantable port and ambulatory pump. Eleven patients (liver metastasis of colorectal cancer, hepatocellular carcinoma and local recurrence of rectal cancer) were treated with continuous arterial infusion chemotherapy at our outpatient clinic. The chemotherapy infusions were carried out repeatedly for 5.7 months on average (10-2 months) with 5-FU or CDDP. Total periods of infusions were 64.8 days on the average (136-24 days). The infusion dose and frequency of drug refilling were limited by pump quality. A major complication occurred only in one patient who developed arterial thrombosis. Minor complications were mainly gastrointestinal symptoms (nausea, vomiting) and abdominal pain, which were easily corrected with drugs. The tumor responses were as follows: PR 1 case, MR 1 case, NC 7 cases and PD 2 cases. Home arterial continuous infusion chemotherapy reduced the hospitalized period and helped patients return to work. Therefore it may well contribute to improve the quality of life of cancer patients.
