Die Reichweite von Theorien als Indikator für ihre Umsetzbarkeit in der Praxis [The scope as an indicator of the applicability of nursing theories to practice]

In der Pflegewissenschaft geben der Einsatz von Theorien und der daraus folgende Gewinn immer wieder Anlass zu Diskussionen. Ein Hauptvorwurf ist, dass Pflegetheorien als sehr abstrakt und wenig praxisnah gelten. Jedoch gibt es wenige Indikatoren, um das Abstraktionsniveau von Theorien und die damit verbundene Reichweite zu bestimmen. Im vorliegenden Artikel werden Fragen basierend auf die Definitionen und Grundannahmen von Theorien erstellt. Damit werden anschließend drei ausgesuchte Theorien auf ihr Abstraktionsniveau und Reichweite untersucht. Es wurden 18 Fragen zu den drei Bereichen ,,Zweck der Theorie", ,,Aufgabe der Theorie" und ,,Beschreibung der Theorie" entwickelt. Diese 18 Fragen wurden auf die Theorie der Adaptation von Sister Callista Roy, die Theorie zur Unsicherheit von Merle M. Mishel und die Theorie der Omnipräsenz von Krebs von Maya Shaha angewendet. [The use of nursing theories and their associated benefits remain an area of repeated discussion in nursing. One of the main objections is that nursing theories are abstract and therefore cannot be easily applied to practice. However, only few indicators exist to help identify a theory's level of abstraction or its scope. In this article, questions based on definitions and assumptions of theories have been developed. These questions have then been applied to three selected theories to investigate their level of abstraction and scope. A total of 18 questions divided into three domains were developed. The three categories were: ,,the purpose of the theory", ,,the aim of the theory" and ,,the description of the theory". The theory of Adaptation by Sister Callista Roy, the Theory of Uncertainty by Merle M. Mishel and the Theory of the Omnipresence of Cancer by Maya Shaha were selected to be analysed following the three domains with the 18 questions.]

Professional Nursing Duties in the Central Services: Hospital Pharmacy Nurses.

Introduction.The new demands of a fast changing world necessitate expanding the traditional concepts of nursing, extending the classical aspects to cover new areas. Purpose. Based on their professional duties, the nursing team in the pharmacy of a second level hospital aimed to establish a theoretical and situational framework for nurses working in the central services. Material and Methods. Application of the nursing process to nursing work in an area with no direct contact with patients. Results and Discussion. The application of the NANDA diagnoses to professional practice enabled the establishment of a nursing diagnosis with the implementation of measures designed to overcome a stressful situation with a risk of becoming unmotivated. Main Conclusion. The capacity to adapt the nursing profession to undertake new roles in the field of healthcare and the power of nursing own methodological resources permit the indirect care of “faceless” patients to be complemented with the inclusion of nurses from other services as clients, forming the focus of care, who can thus be helped with their daily care work.

The neonatal Fc receptor is not required for mucosal infection by mouse mammary tumor virus.

The milk-borne mouse mammary tumor virus (MMTV) infects newborn mice via the intestine. Infection is initially restricted to Peyer's patches and later spreads to the epithelial cells of the mammary gland. The receptor that mediates uptake and transport of MMTV across the intestinal barrier has not yet been identified, The neonatal Fc receptor (nFcR), which is expressed by enterocytes during the first two weeks of life, is downregulated at weaning, and its disappearance correlates with the onset of intestinal resistance to MMTV. To test whether the nFcR mediates transport and allows infection, we foster nursed on infected MMTV mothers beta2 microglobulin-deficient (beta2m-deficient) newborn mice that are unable to express the nFcR at the surface of their enterocytes. Exposure of beta2m-deficient mice to milk-borne virus resulted in the deletion of peripheral blood T cells reactive to the superantigen encoded by MMTV. Since beta2m-deficient newborn mice are susceptible to MMTV infection despite the lack of the nFcR, we conclude that the nFcR is not required for MMTV transport.

Role of bradykinin in the neonatal renal effects of angiotensin converting enzyme inhibition.

The vascular effects of angiotensin converting enzyme inhibitors are mediated by the inhibition of the dual action of angiotensin converting enzyme (ACE): production of angiotensin II and degradation of bradykinin. The deleterious effect of converting enzyme inhibitors (CEI) on neonatal renal function have been ascribed to the elevated activity of the renin-angiotensin system. In order to clarify the role of bradykinin in the CEI-induced renal dysfunction of the newborn, the effect of perindoprilat was investigated in anesthetized newborn rabbits with intact or inhibited bradykinin B2 receptors. Inulin and PAH clearances were used as indices of GFR and renal plasma flow, respectively. Perindoprilat (20 microg/kg i.v.) caused marked systemic and renal vasodilation, reflected by a fall in blood pressure and renal vascular resistance. GFR decreased, while urine flow rate did not change. Prior inhibition of the B2 receptors by Hoe 140 (300 microg/kg s.c.) did not prevent any of the hemodynamic changes caused by perindoprilat, indicating that bradykinin accumulation does not contribute to the CEI-induced neonatal renal effects. A control group receiving only Hoe 140 revealed that BK maintains postglomerular vasodilation via B2 receptors in basal conditions. Thus, the absence of functional B2 receptors in the newborn was not responsible for the failure of Hoe 140 to prevent the perindoprilat-induced changes. Species- and/or age-related differences in the kinin-metabolism could explain these results, suggesting that in the newborn rabbit other kininases than ACE are mainly responsible for the degradation of bradykinin.

Kartagener syndrome: an uncommon cause of neonatal respiratory distress?

We report a newborn with respiratory distress and situs inversus totalis. The diagnosis of primary ciliary dyskinesia was confirmed by both ultrastructural and functional investigations. The immotile cilia syndrome was suspected because of respiratory distress, situs inversus, abnormal nasal discharge and hyperinflated chest X-ray. We suggest that ultrastructural and functional investigations of the respiratory mucosa should be done in any newborn with respiratory distress without explanation for the respiratory problems. Establishment of the correct diagnosis at an early stage may allow to improve the prognosis provided prophylactic physiotherapy, vaccinations, and aggressive antibiotic treatment of intercurrent respiratory infections are instituted. CONCLUSION Despite its rarity, primary ciliary dyskinesia should be considered in unexplained cases of neonatal distress.

Pancreatic stone protein as a novel marker for neonatal sepsis.

PURPOSE: Early-onset sepsis (EOS) is one of the main causes for the admission of newborns to the neonatal intensive care unit. However, traditional infection markers are poor diagnostic markers of EOS. Pancreatic stone protein (PSP) is a promising sepsis marker in adults. The aim of this study was to investigate whether determining PSP improves the diagnosis of EOS in comparison with other infection markers. METHODS: This was a prospective multicentre study involving 137 infants with a gestational age of >34 weeks who were admitted with suspected EOS. PSP, procalcitonin (PCT), soluble human triggering receptor expressed on myeloid cells-1 (sTREM-1), macrophage migration inhibitory factor (MIF) and C-reactive protein (CRP) were measured at admission. Receiver-operating characteristic (ROC) curve analysis was performed. RESULTS: The level of PSP in infected infants was significantly higher than that in uninfected ones (median 11.3 vs. 7.5 ng/ml, respectively; p = 0.001). The ROC area under the curve was 0.69 [95 % confidence interval (CI) 0.59-0.80; p < 0.001] for PSP, 0.77 (95 % CI 0.66-0.87; p < 0.001) for PCT, 0.66 (95 % CI 0.55-0.77; p = 0.006) for CRP, 0.62 (0.51-0.73; p = 0.055) for sTREM-1 and 0.54 (0.41-0.67; p = 0.54) for MIF. PSP independently of PCT predicted EOS (p < 0.001), and the use of both markers concomitantly significantly increased the ability to diagnose EOS. A bioscore combining PSP (>9 ng/ml) and PCT (>2 ng/ml) was the best predictor of EOS (0.83; 95 % CI 0.74-0.93; p < 0.001) and resulted in a negative predictive value of 100 % and a positive predictive value of 71 %. CONCLUSIONS: In this prospective study, the diagnostic performance of PSP and PCT was superior to that of traditional markers and a combination bioscore improved the diagnosis of sepsis. Our findings suggest that PSP is a valuable biomarker in combination with PCT in EOS.

Neonatal treatment with recombinant ectodysplasin prevents respiratory disease in dogs with X-linked ectodermal dysplasia.

Patients with defective ectodysplasin A (EDA) have X-linked hypohidrotic ectodermal dysplasia (XLHED; OMIM#305100), a condition comprising hypotrichosis, inability to sweat, abnormal teeth, and frequent pulmonary infections. The XLHED dogs show the same clinical signs as humans with the disorder, including frequent respiratory infections that can be fatal. The respiratory disease in humans and dogs is thought to be due to the absence of tracheal and bronchial glands which are a vital part of the mucociliary clearance mechanism. In our XLHED model, the genetically missing EDA was replaced by postnatal intravenous administration of recombinant EDA resulting in long-term, durable corrective effect on adult, permanent dentition. After treatment with EDA, significant correction of the missing tracheal and bronchial glands was achieved in those dogs that received higher doses of EDA. Moreover, successful treatment resulted in the presence of esophageal glands, improved mucociliary clearance, and the absence of respiratory infection. These results demonstrate that a short-term treatment at a neonatal age with a recombinant protein can reverse a developmental disease and result in vastly improved quality of life.

Adaptação para a língua portuguesa e validação do Lunney Scoring Method for Rating Accuracy of Nursing Diagnoses

O Lunney Scoring Method for Rating Accuracy of Nursing Diagnoses (LSM) é uma escala de diferencial semântico que foi desenvolvida por Lunney para estimar a acurácia dos diagnósticos de enfermagem. O objetivo deste estudo foi adaptar o LSM para a língua portuguesa e avaliar as sua propriedades psicométricas. A escala original foi traduzida para o português, revertida para o inglês e as duas versões em inglês foram comparadas para ajustar a versão em português que passou a ser denominada Escala de Acurácia de Diagnóstico de Enfermagem de Lunney - EADE. Quatro enfermeiras foram orientadas sobre a EADE e a aplicaram em 159 diagnósticos formulados para 26 pacientes de três estudos primários com base nos registros de entrevista e exame físico de cada paciente. Os índices Kappa de Cohen mostraram ausência de concordância entre as avaliadoras, o que indica que o instrumento adaptado não tem confiabilidade satisfatória. Em virtude desse resultado, não foi realizada estimativa de validade.

Investigação do reflexo vermelho em recém-nascidos e sua relação com fatores da história neonatal

O teste do reflexo vermelho é parte importante do exame ocular do recém-nascido. Buscou-se investigá-lo em recém-nascidos prematuros (RNPT) e sua relação com fatores da história neonatal. Estudo descritivo, exploratório, quantitativo, realizado numa maternidade pública, em Fortaleza-CE, em março, abril e maio de 2004, com 114 RNPTs. Para o registro dos dados, utilizou-se um formulário próprio e para a realização do exame, um oftal-moscópio direto. Considerou-se pertinente os seguintes achados da história neonatal: 68% dos RNPTs obtiveram Apgar inferior a sete no primeiro minuto; 112 utilizaram oxigenoterapia e 68, fototerapia. Quanto ao reflexo vermelho, 13 (11%) apresentaram alteração, com associação estatística significativa entre este e o Apgar no primeiro minuto de vida (p= 0,041). Os achados preocuparam, pois, dez dos 13 RNPTs, com alteração no reflexo vermelho, tinham retinopatia da prematuridade.
