A national survey of epidural use and management in elderly patients undergoing elective and emergency laparotomy.

A postal questionnaire was sent to anaesthetic clinical tutors in the United Kingdom describing two hypothetical 75-year-old patients requiring abdominal surgery. Patient 1 (ASA 2) required elective anterior resection and patient 2 (ASA 3-4) required emergency laparotomy. There was a 65% response rate. For patient 1, 98.5% of respondents would insert an epidural, 93% inserting this awake and 50% placing it in the high-mid thoracic region. All respondents would use local anaesthesia (concentration varied four-fold) and 62% would use opioids. All respondents would place the epidural pre-operatively; although 36% would administer the epidural block pre-operatively and 3% postoperatively. For patient 2, 70% of respondents would insert an epidural (p < 0.0001), drug administration would be more frequently delayed until postoperatively (13%); p = 0.0005) and epidural opioid use decreased (57%); p = n/s. Epidural insertion influenced the postoperative destination in 42% of departments. Use of a critical care facility was anticipated for more than half of these patients; 60% reported difficulty accessing critical care beds.

Breast-feeding, maternal feeding practices and mealtime negativity at one year.

This paper explores whether breast-feeding, mediated by lower maternal use of controlling strategies, predicts more positive mealtime interactions between mothers and their 1 year old infants. Eighty-seven women completed questionnaires regarding breast-feeding, assessing their control over child feeding and mealtime negativity at 1 year of infant age. Seventy-four of these women were also observed feeding their infants solid food at 1 year. Mediation analyses demonstrated that the experience of breast-feeding, mediated by lower reported maternal control over child feeding, predicted maternal reports of less negative mealtime interactions. The experience of breast-feeding also predicted observations of less conflict at mealtimes, mediated by observations of maternal sensitivity during feeding interactions. The implications of these findings are discussed.

Culling avalanches in bootstrap percolation.

We study the culling avalanches which occur after the "death" of a single randomly chosen site in a network where sites are unstable, and are culled, if they have coordination less than an integer parameter m. Avalanche distributions are presented for triangular and cubic lattices for values of m where the associated bootstrap transitions are either first or second order. In second order cases, the culling avalanche distribution is found to be exponential, while in first order cases it follows a power law. We present an exact relation between culling avalanches and conventional bootstrap percolation and show that a relation proposed by Manna [Physica A 261, 351 (1998)] can be a good approximation for strongly first order bootstrap transitions but not for continuous bootstrap transitions.

Efficacy study of THINKable in the attention and memory retraining of traumatically head-injured patients.

The efficacy of computer-assisted attention and memory retraining was evaluated with 15 severely head-injured patients. Training with selected exercises tailored to the individual's needs were provided from the THINKable program for up to 20 hours in both the attention and memory remediation modules. The experimental design evaluated outcome by juxtaposing multiple baseline procedures with a pre- and post-group comparison. Significant results were documented on the computerized tasks, psychometric measures and on patient and observer ratings of everyday behaviours of attention and memory.
