    Notes: Summary This study sought to assess the generalizability of the crying ‘peak’ previously found in Western infants at around 6 weeks of age. To this end, maternal reports and audiorecordings were used to compare the crying patterns of 2, 6 and 12-week-old infants in two cultures expected to differ in their approaches to babycare. As anticipated, Manali mothers were less inclined to leave their babies to cry, took them into their own beds more often, were more likely to be breastfeeding and breastfed their babies to an older age. In spite of these differences, both Manali and London mothers reported their babies to have an evening crying peak, most pronounced at 6 weeks, during this age-range; indicating that this is a general feature of infant development rather than a reflection of Western methods of babycare. Although the maternal reports suggested lower incidences of crying in the Manali infants, the study failed to produce convergent, tape-recorded evidence that this was the case. The definitional and methodological implications of the findings are discussed.

    Notes: A community sample was screened to select three groups of infants and their mothers according to how much the babies cried at 6 weeks of age, the peak age for infant crying. The three groups — of moderate (n = 55), evening (n = 38) and persistent criers (n = 67) and their mothers— were assessed by diary, observation and questionnaire measures of mother and infant characteristics and interactions at 6 weeks and 5 months of infant age. At 6 weeks, mothers of persistent criers spent more time interacting with and physically stimulating their babies. Below-optimum maternal sensitivity/affection was linked to moderately increased crying in the infants overall. However, most mothers of persistent criers showed optimum sensitivity and affection, while no significant links between maternal sensitivity/affection and infant crying were found in the persistent crying group. By 5 months, when infant crying declined, the range and size of differences between mothers of persistent criers and other mothers declined. Home observations and a standard play measure failed to show group differences in maternal sensitivity, affection and intrusiveness at this age. The findings show that persistent infant crying in the early months often occurs in spite of high quality maternal care, so that in most cases the crying is probably not due to inadequate parenting. The need to distinguish general community cases from those at social or medical risk is emphasized and the findings’ implications for professionals are discussed.

    Notes: Aim  This paper describes a process evaluation that was conducted alongside a randomized controlled trial of out-of-home pre-school day care. The evaluation aimed to: (1) describe the intervention; (2) document the day care received by participating families; (3) describe the social context of the trial; and (4) provide data to assist in the interpretation of trial outcomes.Methods  The setting for the trial was an out-of-home day care Centre in Hackney, East London. Process data were collected through the use of questionnaires, interviews, and researcher field-notes. Data from questionnaires were collected from 120 mothers and included data on 143 children. Interviews were undertaken with 21 participating mothers. Staff also completed questionnaires and the Head of the Centre was interviewed. The quality of care provided was assessed using the Early Childhood Environment Rating Scale.Results  Process data collected during the trial suggest that the day care provided was education-led, flexible in catering to families’ needs, and was of a very high quality. The social context of the trial resulted in financial pressures, which may well have influenced the intervention provided. Data collected through in-depth interviews suggested that it may be the flexibility of day care that is particularly important in allowing women to return to paid employment, but that the loss of benefits when starting work may have meant no increase in household income.Conclusion  The paper illustrates the value of conducting a process evaluation alongside a randomized trial, particularly where complex interventions are involved. In this case, where the intervention was not provided by the research team, the evaluation allowed an insight into the content of a multifaceted intervention, which is useful in interpreting the trial's results, and in explaining the possible effects of the social context on the intervention.

    Notes: The complete nucleotide sequence has been determined of a region of the Escherichia coli K5 antigen gene cluster postulated to encode functions for the translocation of capsular polysaccharide across the inner membrane. This revealed two genes, designated kpsM and kpsT, organized in a single transcriptional unit. Analysis of the predicted amino acid sequence of the KpsM and KpsT proteins indicates that they may function as dual components in a polysaccharide export system analogous to the periplasmic binding protein-dependent transport systems of Gram-negative bacteria. We propose that the KpsT protein acts as an energizer, coupling ATP hydrolysis to the transport process mediated by the KpsM protein. Extensive sequence homology between the KpsM and KpsT proteins and the products of the bexB and bexA genes present in the capsulation (cap) locus of Haemophilus influenzae, indicates that a common mechanism for the export of polysaccharide across the inner membrane may exist in these two microorganisms.

    Notes: A nonpathogenic Erwinia amylovora transposon mutant that has an insertion in the guaB gene was isolated. The mutation results in a nutritional requirement for guanine or xanthine, and loss of ability to produce ooze on immature pear fruit and to cause symptoms in the apple seedling assay. The mutant expressed other known virulence determinants including extracellular polysaccharide and had an intact hrp/dsp cluster. In addition it was able to grow in host tissue, although the population size in planta was maintained at a considerably lower level than that seen with the parent strain. The inability of the Erwinia amylovora guaB mutant to cause disease indicates that levels of guanine in plant tissue are likely to be insufficient to maintain optimal growth via the purine salvage pathway. This, in turn, appears to compromise the ability of the mutant to develop a sufficiently large population size in planta to overcome host defence mechanisms and cause disease symptoms. This indicates that a functional de novo guanine synthetic pathway is important for Erwinia amylovora to grow on plant tissue and cause disease.

    Notes: Less invasive or non-invasive alternatives to the complete autopsy have been sought for some time, and a range of methods, ranging from needle sampling to endoscopy to magnetic resonance imaging, have been considered. Evaluations of these methods are few and far between, but generally confirm the predictable conclusion that incomplete autopsies provide incomplete information. It is not difficult to envisage a situation whereby pressure for non-invasive autopsies will allow them to become prevalent, whether properly evaluated or not. However, used appropriately, non-invasive or less invasive autopsies may be valuable tools capable of answering specific questions in situations where it is not possible to perform a complete autopsy.
