A study of marketing and its effect on infant feeding practices.

A baby milk market was created in the late nineteenth and early twentieth centuries and was conceived through the mutual attraction of the manufacturers and doctors. This has partly attributed to the change from breast to artificial feeding. This study was conducted to determine whether marketing had any effect on infant feeding practices. Fifty Malay mothers whose last child was aged less than five years were asked, by questionnaire and by interview, to identify whether several marketing methods influenced their decision on the selection of infant feeding practice. It was found that these mothers felt milk advertisements on television were attractive (72%), were influenced by others to buy a particular brand of formula (38.4%), were influenced by free milk samples to buy a particular brand of milk formula (65.2%) and were not influenced by their doctors on the chosen method of feeding (68%). More studies should be conducted on a bigger sample in other settings and targeting other methods of marketing to substantiate the above results. Further, similar studies among Chinese and Indian mothers are also required.

[Cardiopulmonary exercise evaluation: value and influence of the use of a ramp protocol versus triangular protocol].

The aim of the study was to evaluate a ramp bicycle ergometer exercise protocol consisting of a very small but rapid increase in load (2 watts/12 seconds) for direct measurement of the VO2 max. Eighteen sedentary healthy subjects were in Group I (16 men, mean age 29 +/- 6 years) and 10 men with chronic stable cardiac failure in Group II (mean age: 51 +/- 16 years). All subjects performed two exercise tests within a period of 8 days, one with a ramp protocol (protocol R) and the other with a standard triangular exercise protocol (protocol T) of 30 watts/3 minutes for Group I and 20 watts/2 minutes for Group II. All procedures were performed until the subjects were exhausted. Direct measurement of VO2 max was performed by rapid response analysers enabling a cycle to cycle study. The parameters were measured and compared by a paired Student t test at each stage of the test: at rest, at submaximal exercise (third level), at anaerobic threshold and at maximal exercise. There was no significant difference between VO2 max and VO2 at the threshold of ventilation between the two populations. An increase in carbon dioxide production at different stages was observed with the ramp protocol. Furthermore, the highest maximal respiratory quotient and anaerobic threshold appeared earlier in Group II with the ramp protocol. Therefore, with respect to the standard triangular protocol, the ramp protocol provides comparable VO2 values. Its potential value, reported in the literature, is a better correlation between the observed and theoretical VO2 values. However, an increase in CO2 production should be underlined, probably related to greater recruitment of anaerobic metabolism in the absence of a steady state. This may be the reason for attaining the anaerobic threshold earlier.

Ultrasound assessment of normal splenic length and spleen-to-kidney ratio in children.

Splenic lengths in 184 normal Jordanian children were measured through the hilum by ultrasound and compared with data from Hong Kong and the United States of America. The spleen to left kidney ratio was calculated to determine whether it was constant and to establish a ratio above which splenomegaly can be diagnosed. Up to age 15 years, little variation in splenic length was observed, but over 15 years splenic length was slightly lower in Jordanian males. Spleen to left kidney ratio was constant at around 1; splenomegaly is highly probable in ratios > or = 1.25.
