Early pain experience, child and family factors, as precursors of somatization:a prospective study of extremely premature and fullterm children

In a prospective study of 36 children who were extremely low birthweight (ELBW: <1000 g) preterm infants and 36 matched full-term controls, differences were found in somatization at age 4 1/2 years. Only children who had been extremely premature, and thereby experienced prolonged hospitalization and repeated medical intervention in infancy, had clinically high somatization scores on the Personality Inventory for Children. The combination of family relations at age 4 1/2 years, neonatal intensive care experience, poor maternal sensitivity to child cues in mother-child interaction observed at age 3 years, and child avoidance of touch or holding at age 3, predicted somatization scores, prior to school entry. Due to the known higher incidence of actual medical problems among children with a history of extreme prematurity, the high somatization ELBW children were compared with the normal somatization ELBW children. There were no differences in prevalence of actual medical problems between the 2 ELBW groups, and the importance of maternal factors in relation to somatization was confirmed. Child temperament at age 3, but not personality at 4 1/2, was related to somatization. The etiology of recurrent physical complaints of no known medical cause appears to be a multi-dimensional problem. Non-optimal parenting may contribute to the development of inappropriate strategies for coping with common pains of childhood, or of chronic pain patterns, in some children who have experienced prolonged or repeated pain as neonates.

Adjustment in children with intractable epilepsy:importance of seizure duration and family factors

Seventy-five families of children with intractable epilepsy but without a severe learning disability (mean age 7 years 1 month, SD 2 years 6 months; range 2 to 12 years) who attended a regional paediatric neurology service, were surveyed. A postal questionnaire was used which included standardized measures of child and family adjustment; forty-eight families responded (64%; 31 males, 17 females). There was no significant difference between responders and non-responders in terms of age, sex, number of other chronic illnesses and disabilities, age at epilepsy diagnosis, seizure type, nor number of antiepileptic drugs currently prescribed (p > 0.05). The importance of including multidimensional measures of outcome was highlighted by the finding that epilepsy, pharmacological, and psychosocial factors were differentially associated with specific adjustment difficulties. Two factors appeared to be most pervasively implicated across a range of adjustment problems: frequency of rectal diazepam administration and family patterns of relating to each other (p <0.05). It appeared that duration of seizures (as indicated by frequency of rectal diazepam administration), rather than the frequency of seizures per se, was more pernicious in terms of poor adjustment. Intrafamilial relations (degree of conflict/cohesion and soon) were not only associated with adjustment difficulties in the child, but also with the frequency of seizures themselves. Implications for psychological interventions in intractable epilepsy in childhood are highlighted.

The two-way relationship between the Balanced Scorecard and Management Control Systems in organizations:Lessons from a Case Study

This paper reports a case study conducted in Quinta da Aveleda, one of
the three largest Portuguese wine companies. Our aim was to explore the
relationship established between a newly implemented Balanced Scorecard
(BSC) and the elements of the Management Control System (MCS) in the
organization. Thus, two specific objectives were pursued. Firstly, to identify
the influences (barriers, opportunities) of the existing MCS on the implementation
of the BSC. Secondly, to identify the impacts the BSC implementation
was able to exert on the configuration of the organization’s MCS.
We found that the budgeting process, the planning system, the information
infrastructure, and the organizational structure and culture were the elements
of the previous MCS that influenced the BSC implementation process.
Eventually, the BSC implementation led to important changes in the budgeting,
planning, reporting systems and processes. In order to explain these
findings, we briefly explored the main issues and factors accounting for the
scope and nature of the BSC’s impacts on Quinta da Aveleda. These issues
and factors were the mobilized organizational resources, the implementation
approach, the communication, and the organizational support.

Interleukin 3 and schizophrenia:the impact of sex and family history

Chromosome 5q21-33 has been implicated in harboring risk genes for schizophrenia. In this paper, we report evidence that multiple single nucleotide polymorphisms in and around interleukin 3 (IL3) are associated with the disease in the Irish Study of High-Density Schizophrenia Families (ISHDSF), the Irish Case-Control Study of Schizophrenia (ICCSS) and the Irish Trio Study of Schizophrenia (ITRIO). The associations are sex-specific and depend on the family history (FH) of schizophrenia. In all three samples, rs31400 shows female-specific and FH-dependent associations (P=0.0062, 0.0647 and 0.0284 for the ISHDSF, ICCSS and ITRIO, respectively). Several markers have similar associations in one or two of the three samples. In haplotype analyses, identical risk and protective haplotypes are identified in the ISHDSF and ITRIO samples in several multimarker combinations. For ICCSS, the same haplotypes are implicated; however, the risk haplotypes observed in the family samples become protective. Several significant markers, rs440970, rs31400 and rs2069803, are located in and around known estrogen response elements, promoter and enhancer of the IL3 gene. They may explain the sex-specific associations and be functional for the expression of IL3 gene.

Neonatal intensive care and late preterm infants:Health and family functioning at three years

Background: Late preterm infants (LPIs), born at 34 + 0 to 36 + 6 weeks of gestation contribute a significant proportion of all neonatal intensive care (NIC) admissions and are regarded as being at risk of adverse outcomes compared to term-born infants.

Aim: To explore the health outcomes and family functioning of LPIs who required neonatal intensive care, at three years of age.

Study design and subjects: This cohort study included 225 children born late preterm, between 1 January and 31 December 2006 in Northern Ireland. Children admitted for NIC (study group, n = 103) were compared with children who did not require NIC or who required special care only for up to three days (comparison group, n = 122).

Outcome measures
Health outcomes were measured using the Health Status Questionnaire, health service usage by parent report and family functioning using the PedsQL™ Family Impact Module.

Results: LPIs who required NIC revealed similar health outcomes at three years in comparison to those who did not. Despite this, more parents of LPIs who required NIC reported visiting their GP and medical specialists during their child's third year of life. Differences in family functioning were also observed with mothers of LPIs who required NIC reporting, significantly lower levels of social and physical functioning, increased difficulties with communication and increased levels of worry.

Conclusions: LPIs were observed to have similar health outcomes at three years of age regardless of NIC requirement. The increase in GP and medical specialist visits and family functioning difficulties observed among those infants who required NIC merits further investigation.

Distillable entanglement and area laws in spin and harmonic-oscillator systems

We address the presence of nondistillable (bound) entanglement in natural many-body systems. In particular, we consider standard harmonic and spin-1/2 chains, at thermal equilibrium and characterized by few interaction parameters. The existence of bound entanglement is addressed by calculating explicitly the negativity of entanglement for different partitions. This allows us to individuate a range of temperatures for which no entanglement can be distilled by means of local operations, despite the system being globally entangled. We discuss how the appearance of bound entanglement can be linked to entanglement-area laws, typical of these systems. Various types of interactions are explored, showing that the presence of bound entanglement is an intrinsic feature of these systems. In the harmonic case, we analytically prove that thermal bound entanglement persists for systems composed by an arbitrary number of particles. Our results strongly suggest the existence of bound entangled states in the macroscopic limit also for spin-1/2 systems.
