Direct and indirect nursing care time in an Intensive Care Unit

OBJECTIVE: to identify the direct and indirect nursing care time in an Intensive Care Unit. METHOD: a descriptive/exploratory study conducted at a private hospital. The Nursing Activities Score classification system was used to estimate the direct care time, and electronic health records were used to estimate the indirect care time. The data were collected from March to June 2011. RESULTS: the findings indicate that the average nursing care time was 29.5 hours, consisting of 27.4 hours of direct care and 2.1 hours of indirect care per patient/day. The nursing care time was higher on weekends and holidays, with predominant use of electronic medical records at night. CONCLUSION: ascertaining nursing care times will contribute to a quantitative evaluation of human resources, assisting in the determination of workloads and workforce size

Beckwith–Wiedemann syndrome and uniparental disomy 11p: fine mapping of the recombination breakpoints and evaluation of several techniques

Beckwith–Wiedemann syndrome (BWS) is a phenotypically and genotypically heterogeneous overgrowth syndrome characterized by somatic overgrowth, macroglossia and abdominal wall defects. Other usual findings are hemihyperplasia, embryonal tumours, adrenocortical cytomegaly, ear anomalies, visceromegaly, renal abnormalities, neonatal hypoglycaemia, cleft palate, polydactyly and a positive family history. BWS is a complex, multigenic disorder associated, in up to 90% of patients, with alteration in the expression or function of one or more genes in the 11p15.5 imprinted gene cluster. There are several molecular anomalies associated with BWS and the large proportion of cases, about 85%, is sporadic and karyotypically normal. One of the major categories of BWS molecular alteration (10–20% of cases) is represented by mosaic paternal uniparental disomy (pUPD), namely patients with two paternally derived copies of chromosome 11p15 and no maternal contribution for that. In these patients, in addition to the effects of IGF2 overexpression, a decreased level of the maternally expressed gene CDKN1C may contribute to the BWS phenotype. In this paper, we reviewed a series of nine patients with BWS because of pUPD using several methods with the aim to evaluate the percentage of mosaicism, the methylation status at both loci, the extension of the pUPD at the short arm and the breakpoints of recombination. Fine mapping of mitotic recombination breakpoints by single-nucleotide polymorphism-array in individuals with UPD and fine estimation of epigenetic defects will provide a basis for understanding the aetiology of BWS, allowing more accurate prognostic predictions and facilitating management and surveillance of individuals with this disorder
