Nursing prioritization of the patient need for care: A tacit knowledge embedded in the clinical decision-making literature

Every day in clinical settings, nurses practise in complex and dynamic situations. Nurses work to achieve emergent order in these situations through nursing prioritization of the patient need for care. As direct research on nursing prioritization had not been reported, a study, using critical realism as method, was designed to discern the profession's embedded understanding from within the clinical decision-making literature. The research synthesizes a tacit knowledge on nursing prioritization of the patient need for care from key international literature (from 1966 to 2003). Nursing prioritization was discerned in both education and practice literatures; interrelationships between these and theoretical approaches were also identified. Nursing prioritization of the patient need for care was revealed both as a non-sequential decision-making process throughout unfolding patient situations and as an advanced skill of nursing practice. Increasing confidence with this skill is the hallmark of developing expertise.     

Molecular characterization of CTX‐M‐15‐producing clinical isolates of Escherichia coli reveals the spread of multidrug‐resistant ST131 (O25:H4) and ST964 (O102:H6) strains in Norway

Nationwide, CTX‐M‐producing clinical Escherichia coli isolates from the Norwegian ESBL study in 2003 (n=45) were characterized on strain and plasmid levels. Bla_CTX‐M allele typing, characterization of the genetic environment, phylogenetic groups, pulsed field gel electrophoresis (PFGE), serotyping and multilocus sequence typing were performed. Plasmid analysis included S1‐nuclease‐PFGE, polymerase chain reaction‐based replicon typing, plasmid transfer and multidrug resistance profiling. Bla_CTX‐M‐15 (n=23; 51%) and bla_CTX‐M‐14 (n=11; 24%) were the major alleles of which 18 (78%) and 6 (55%), respectively, were linked to ISEcp1. Thirty‐two isolates were of phylogenetic groups B2 and D. Isolates were of 29 different XbaI‐PFGE‐types including six regional clusters. Twenty‐three different O:H serotypes were found, dominated by O25:H4 (n=9, 20%) and O102:H6 (n=9, 20%). Nineteen different STs were identified, where ST131 (n=9, 20%) and ST964 (n=7, 16%) were dominant. Bla_CTX‐M was found on ≥100 kb plasmids (39/45) of 10 different replicons dominated by IncFII (n=39, 87%), FIB (n=20, 44%) and FIA (n=19, 42%). Thirty‐nine isolates (87%) displayed co‐resistance to other classes of antibiotics. A transferable CTX‐M phenotype was observed in 9/14 isolates. This study reveals that the majority of CTX‐M‐15‐expressing strains in Norway are part of the global spread of multidrug‐resistant ST131 and ST‐complex 405, associated with ISEcp1 on transferrable IncFII plasmids.     

The acceptability of waiting times for elective general surgery and the appropriateness of prioritising patients

Background  

Problematic waiting lists in public health care threaten the equity and timeliness of care provision in several countries. This study assesses different stakeholders' views on the acceptability of waiting lists in health care, their preferences for priority care of patients, and their judgements on acceptable waiting times for surgical patients.     

26万女性队列人群中乳腺癌与人工流产关系的研究（上海）

目的：评估人工流产（指手术流产）对乳腺癌危险性的可能影响。方法：研究在上海267040例妇女的一项乳房自我检查随机试验的队列人群中进行，由队列研究和巢式病例对照研究两部分组成。结果：依据基线调查表采集的资料分析，人工流产不增加乳腺癌危险性。调整潜在的混淆因素后，OR=1．06（95％CI：0．91～1．25）。人工流产次数增加无危险性趋势增加。从更详细的652例乳腺癌病例和694例对照资料分析，得出相似的结果。人工流产发生在首次生育后不增加危险性；少数妇女在首次生育前人工流产以及妊娠13周后人工流产，虽然被观察到危险性有增加，但无显著性统计学意义。结论：在中国，人工流产不是乳腺癌发生的重要原因。     

Selected Trace Elements and Proteins in Serum of Apparently Healthy Newborn Infants of Mothers Who Smoked during Pregnancy

ABSTRACT. The serum concentrations of selected trace elements and proteins in cord blood from 17 new-bom infants whose mothers were habitual smokers were compared with values from 22 infants of non-smoking mothers. All the mothers were healthy with normal pregnancies and deliveries. Cigarette smoke exposure was verified by determinations of nicotine, cotinine and thiocyanate concentrations in cord blood. Infants of smoking mothers had a slightly lower mean birth weight (3490±430 g) than control infants (3780±460 g). Infants of smokers had lower serum iron ( p =0.05) and prealbumin ( p ≤0.05), but higher serum copper ( p ≤0.05) and ceruloplasmin ( p ≤0.01) levels than the controls. Infants of smoking mothers tended to have higher levels of the acute-phase reactants alpha-₂-macroglobulin and orosomucoid, but lower levels of albumin, transferrin and retinol-binding-protein, although differences were not statistically significant.
