Mechanisms and control of nutrient uptake in plants.

This review is a distillation of the vast amount of physiological and molecular data on plant membrane transport, to provide a concise overview of the main processes involved in the uptake of mineral nutrients in plants. Emphasis has been placed on transport across the plasma membrane, and on the primary uptake from soil into roots, or in the case of aquatic plants, from their aqueous environment. Control of uptake has been mainly considered in terms of local effects on the rate of transport and not in terms of long-distance signaling. The general picture emerging is of a large array of membrane transporters, few of which display any strong selectivity for individual nutrients. Instead, many transporters allow low-affinity uptake of several different nutrients. These features, plus the huge number of potential transporter genes that has been revealed by sequencing of plant genomes, raise some interesting questions about their evolution and likely function.

A national survey in England of the routine examination of the newborn baby.

OBJECTIVE: To identify current practices for the initial routine examination of healthy newborn babies, and determine the extent to which midwives are carrying out this examination. DESIGN AND PARTICIPANTS: Postal questionnaires were sent to consultant paediatricians and midwifery managers in all maternity units in England. Questionnaires were also sent to the 12 universities in England which run the N96 post-registration course in the examination of the newborn baby. FINDINGS: Questionnaires were returned from 197 (86%) maternity units. Senior house officers examined in 83% (160/193) a median of 92% of babies; 44% (74/167) had at least one midwife (median of two) with qualifications to carry out the examination and in 31% (51/167) some examinations were conducted by a midwife. However, a third of midwives with this qualification carried out no examinations, and nationally only about 2% of babies were examined by a midwife. Rates of referral by midwives and senior house officers were similar. Examinations were carried out between four and 48 hours from birth; most units considered six hours an acceptable minimum. An estimated 1% of babies were transferred home without routine examination; the GP was responsible for most (83-93%) of these babies' examinations; midwives for 10-23%; and senior house officers in hospital for 4-7%. Twelve per cent (23/194) of units carried out a second examination prior to discharge. Most respondents were in favour of midwives carrying out the examinations provided they were adequately trained. CONCLUSIONS: Many of the consultant paediatricians and midwifery managers stated that suitably trained midwives could routinely examine the healthy newborn baby; however, many currently N96 trained midwives were examining few or no babies. An extension of training would be needed were midwife examination to become general policy.

A randomised controlled trial of maternal satisfaction with the routine examination of the newborn baby at three months post birth.

OBJECTIVE: to determine whether any differences in maternal satisfaction with the examination of a newborn baby between midwives and junior paediatricians are maintained over a three-month period. DESIGN, SETTING AND PARTICIPANTS: randomised controlled trial. Eight hundred and twenty-six mother and baby pairs in a district general hospital in South East England were randomised to a junior paediatrician or a midwife for the routine examination. Four hundred and eighty-six mothers completed a maternal satisfaction questionnaire on day-one and again three-months later. Maternal satisfaction with the examination was analysed in relation to randomised group, process and background variables. FINDINGS: high satisfaction with the examination was reported by most mothers (day-one: 82%; three-months: 79%). At day-one, mothers whose babies were examined by a midwife were more satisfied with the examination (crude odds ratio (OR) for the lowest tertile of satisfaction 0.49, 95% CI 0.32-0.73). However, after controlling for provision of health education during the examination (e.g. discussing feeding, sleeping and skin care) and continuity of care provided, maternal satisfaction was no longer related to status of examiner (adjusted OR 0.83, 95% CI 0.52-1.33). Three months later, there was no significant difference in maternal satisfaction with midwife and junior paediatrician examinations of the newborn baby (crude OR 0.89, 95% CI 0.58-1.37). Discussion of health-care issues by the examiner during the examination was significantly related to increased satisfaction even at three-months. Three month ratings of low satisfaction with the examination were most strongly predicted by current maternal depressive mood, even when other factors were adjusted for (adjusted OR 2.58, 95% CI 1.19-5.59). KEY CONCLUSIONS: from the mother's perspective, the quality of midwife examination is at least as satisfactory as that of junior paediatricians and this perception is maintained over a three-month period. Satisfaction can be significantly enhanced if the examiner provides information on behavioural and health-care issues. The examination of the newborn baby provides an important window of opportunity for sharing information on newborn behaviour and care issues.
