Effects of submaximal exercise with water ingestion on intraocular pressure in healthy human males

The effects of exercise and water replacement on intraocular pressure (IOP) have not been well established. Furthermore, it is not known whether the temperature of the fluid ingested influences the IOP response. In the present study we determined the effect of water ingestion at three temperatures (10, 24 and 38ºC; 600 ml 15 min before and 240 ml 15, 30 and 45 min after the beginning of each experimental session) on the IOP of six healthy male volunteers (age = 24.0 ± 3.5 years, weight = 67.0 ± 4.8 kg, peak oxygen uptake (VO2peak) = 47.8 ± 9.1 ml kg-1 min-1). The subjects exercised until exhaustion on a cycle ergometer at a 60 percent VO2peak in a thermoneutral environment. IOP was measured before and after exercise and during recovery (15, 30 and 45 min) using the applanation tonometry method. Skin and rectal temperatures, heart rate and oxygen uptake were measured continuously. IOP was similar for the right eye and the left eye and increased post-water ingestion under both exercising and resting conditions (P<0.05) but did not differ between resting and exercising situations, or between the three water temperatures. Time to exhaustion was not affected by the different water temperatures. Rectal temperature, hydration status, heart rate, oxygen uptake, carbon dioxide extraction and lactate concentration were increased by exercise but were not affected by water temperature. We conclude that IOP was not affected by exercise and that water ingestion increased IOP as expected, regardless of water temperature

[Diabetes mellitus: training of health teams at the university]. / Diabetes mellitus: a universidade no treinamento de equipes das unidades básicas de saúde.

The authors describe their experience as a multiprofessional team working at two Basic Health Units (BHU) in Londrina city in 1995. The work involved medical, nursing students and residents. The goals were: a) to train BHU teams in the assistance of diabetic patients; b) expose students to teaching experiences at the BHUs, emphasizing multiprofessionality; c) to establish an hierarchy and provide suitable treatment for the BHUs diabetic clientele. A total of 106 diabetic patients were assisted. The project involved 22 students and 37 professionals. A questionnaire assessment indicated that the goals were achieved. The experience is considered valid as a teaching and inservice training.

[Evaluation of theoretical knowledge of diabetics in an interdisciplinary program]. / Avaliação dos conhecimentos teóricos dos diabéticos de um programa interdisciplinar.

Using an instrument of evaluation of theoretical knowledge, the authors have assessed the capacity of understanding and memorizing often groups of diabetes' carriers, that were being followed by a multiprofessional team from the ambulatory of the HURNP. The evaluation included the discussion of a variety of subjects which were part of the activities of an Educational Program. Only one group of patients showed a satisfactory performance. Individual analysis showed that young diabetes' carriers, that were motivated and had good level of understanding, had a better performance. It was concluded that the evaluation allows the selection of patients that need specific reinforcement and that a plan of activities can be elaborated according to the tested subjects.
