The influence of diet quality and stage of lactation on Cheddar cheese moisture and yield were segregated and the effects of other potential variables (cow breed, milk protein genotype, age and level of mastitis) were minimized. An experiment was conducted using milk of cows in mid lactation or late lactation fed on high or low quality diets. Increased moisture in cheese was largely due to the influence of cow diet. Milk from cows given high quality diets produced lower moisture cheese. Cheese yield was influenced by diet and stage of lactation. Cows in late lactation fed on high quality diets always gave milks yielding the most cheese. Fat and protein recovery in cheese was not influenced by diet or stage of lactation. The results suggest that low quality diets may induce changes in the complex interactions of milk proteins and other components that affect cheesemaking.

Day surgery--how much is possible? A Delphi consensus among surgeons.

Although day surgery (DS) has been performed for many years, it has only relatively recently become a popular and acceptable method of treating many common surgical conditions. With considerable pressure to maximise resource usage DS has been seized upon as a way of stretching scarce resources further. A review of the amount of DS undertaken within the West Midlands region revealed that the current workload showed considerable variation both between districts and between consultants. In an effort to gain clinical commitment to increasing generally the amount of DS undertaken, and obtaining more uniform coverage of DS across the region, a consensus conference was held. The two aims of the conference were to set targets as to the amount of DS considered feasible at a procedural level, and to seek clinicians' views as to the obstacles to developing the service. Targets for 43 procedures at one and/or five years were obtained by the use of a modified Delphi consensus. The groups showed a high level of consensus in the targets reached. A variety of obstacles were discussed. We have shown that it is possible to involve a large number of doctors in the decision-making/target-setting process by using a modified Delphi technique. It remains to be seen whether those targets are met in clinical practice. Surprisingly, obstacles to development were mainly concerned with management and personnel issues rather than capital investment.

Assault on staff in psychiatric hospitals: a safety issue.

All reported injuries between 1985 and 1987 in a large Queensland psychiatric hospital were studied. There were 650 incidents investigated; travelling injuries and injuries sustained by staff members not involved with patient care were excluded. Forty-eight per cent (n = 323) were assault based injury. Student nurses were most frequently assaulted. It was concluded that training in aggression management should include both counselling and self defence techniques, and that patient and staff rights should be balanced. Student nurses should have experience in wards with a low injury rate, prior to being rostered to the high risk wards.
