Self-reported integration as a proxy for acculturation: a qualitative study

BACKGROUND: It is essential to account for acculturation in any research conducted in multicultural populations. Both unidimensional and bidimensional approaches are used to measure the extent of acculturation; however, neither one of them is optimal. OBJECTIVE: To explore the immigrants' rating of the extent of their acculturation (self-reported integration) in contrast to an external (researchers') measurement. METHODS: Fifteen in-depth interviews with strategically sampled Russian-speaking men and women aged 25-70 years, with varying marital and employment status and living permanently in Stockholm, Sweden, were analyzed using a content analysis technique. The results were validated by means of a series of additional mini-interviews by telephone. RESULTS: The immigrants' self-reported integration corresponded with the researchers' bidimensional measurement of the extent of acculturation of these immigrants. Self-reported integration accounted for the mastering of the formal criteria of integration, resolving of grief concerning the homeland, and fulfilling the internal criteria of integration. DISCUSSION: Self-reported integration may be used as a proxy for acculturation but its application should be tested primarily in other settings and in a quantitative analysis.     

Should nurses prescribe blood components?

AIM: To explore the feasibility of nurses prescribing blood components. METHOD: Using a convenience snowball sample, a UK-wide questionnaire survey was undertaken to identify transfusion practices and canvass the opinions of nurses and doctors. RESULTS: A total of 179 (59%) of 302 respondents were supportive of nurses prescribing blood components, saying it would have a positive effect on the quality of patient care, result in fewer treatment delays and help doctors and nurses to use their time more effectively. The remaining 123 (41%) respondents had reservations about time and resource constraints and worries about undermining medical care and responsibility. CONCLUSION: Development of non-medical prescribing to allow nurses to prescribe blood components has the potential to deliver a more patient-centred quality service.     

Acute hypoxia due to right to left blood shunting in a patient with atrial septal defect

Acute right to left blood shunt is an unusual cause of acute hypoxia. We describe a case of a patient with an atrial septal defect who developed acute hypoxia due to cardiac tamponade. Acute haemopericardium developed as a complication of temporary transvenous cardiac pacing. Bubble contrast echocardiography confirmed right to left blood shunting at the atrial level. Acute hypoxaemia and the right to left blood shunt resolved when the pericardium was drained. The case underscores the importance of evaluating the presence of an intracardial shunt in patients with otherwise inexplicable hypoxia.     

Competencies and skills for remote and rural maternity care: a review of the literature

AIM: This paper reports a review of the literature on skills, competencies and continuing professional development necessary for sustainable remote and rural maternity care. BACKGROUND: There is a general sense that maternity care providers in rural areas need specific skills and competencies. However, how these differ from generic skills and competencies is often unclear. METHODS: Approaches used to access the research studies included a comprehensive search in relevant electronic databases using relevant keywords (e.g. 'remote', 'midwifery', 'obstetrics', 'nurse-midwives', education', 'hospitals', 'skills', 'competencies', etc.). Experts were approached for (un-)published literature, and books and journals known to the authors were also used. Key journals were hand searched and references were followed up. The original search was conducted in 2004 and updated in 2006. FINDINGS: Little published literature exists on professional education, training or continuous professional development in maternity care in remote and rural settings. Although we found a large literature on competency, little was specific to competencies for rural practice or for maternity care. 'Hands-on' skills courses such as Advanced Life Support in Obstetrics and the Neonatal Resuscitation Programme increase confidence in practice, but no published evidence of effectiveness of such courses exists. CONCLUSION: Educators need to be aware of the barriers facing rural practitioners, and there is potential for increasing distant learning facilitated by videoconferencing or Internet access. They should also consider other assessment methods than portfolios. More research is needed on the levels of skills and competencies required for maternity care professionals practising in remote and rural areas.     

Macrolide-resistant Staphylococcus aureus colonization in cystic fibrosis patients: is there transmission to household contacts?

OBJECTIVES: Patients with cystic fibrosis (CF) are frequently colonized by macrolide-resistant Staphylococcus aureus, a result of maintenance macrolide therapy. As transmission of S. aureus between household contacts is common, we examined the prevalence of macrolide-resistant S. aureus colonization in CF patients on maintenance azithromycin therapy and their household contacts and compared this with the S. aureus macrolide resistance prevalence in the community. PATIENTS AND METHODS: Sixty-five CF patients on maintenance macrolide therapy and 194 household contacts were screened for S. aureus colonization by culturing sputa, cough swabs and nasal swabs. Resistance to macrolide, lincosamide and methicillin was determined by disc diffusion tests. The prevalence of macrolide-resistant S. aureus colonization in both groups was compared with figures from a nationwide study into S. aureus carriership and resistance. To assess possible transmission, genotyping of S. aureus was performed using the spa-typing method. RESULTS: Macrolide resistance among CF patients with S. aureus colonization was 69.6%; 75% of these isolates displayed lincosamide resistance too. Among household contacts, macrolide resistance prevalence did not differ significantly from resistance prevalence in the community (9.6% versus 6.3%; P = 0.358). No methicillin resistance was observed. No identical (macrolide-resistant and -susceptible) S. aureus genotypes were observed between CF patients and their household contacts except for one household, suggesting a probable transmission. CONCLUSIONS: No significant increase in macrolide-resistant S. aureus colonization was observed among household contacts of CF patients on long-term azithromycin therapy. Transmission of macrolide-resistant S. aureus could not be proved by genotyping in the majority of households.     

Serum and intraperitoneal levels of amphotericin B and flucytosine during intravenous treatment of critically ill patients with Candida peritonitis

OBJECTIVES: To study the relation between serum and peritoneal levels of amphotericin B and flucytosine during intravenous treatment in patients with abdominal sepsis due to a perforated gut. PATIENTS AND METHODS: Included were consecutive patients with abdominal sepsis due to a perforated gut, who were treated intravenously with amphotericin B and/or flucytosine after surgery if an abdominal drain was present. Amphotericin B and flucytosine were measured from simultaneously collected serum and abdominal fluid samples. RESULTS: Twenty-one consecutive patients were included. Five repeated samples were taken from three patients. The time interval between the start of the medication and the first sampling was median 4.0 days (range 2-7 days). The correlation coefficient (r(2)) between serum and peritoneal levels of amphotericin B was 0.79. In nine patients (43%) with a maximum serum level of 0.28 mg/L, amphotericin B in the peritoneal fluid was undetectable. The lowest serum level that was present with a detectable peritoneal level was 0.16 mg/L. A short duration of treatment (2 days) was associated with low serum and undetectable peritoneal levels. In seven patients, flucytosine levels were measured. Peritoneal flucytosine levels did not differ significantly from serum levels. Serum and peritoneal flucytosine levels correlated well with r(2)=0.88. Peritoneal amphotericin B level was inversely correlated with C-reactive protein level on the same day (r(2)=0.30). CONCLUSIONS: It is shown, during continuous infusion, that peritoneal levels of amphotericin B are lower than serum levels. The amphotericin B serum levels should exceed 0.5 mg/L to obtain peritoneal levels above MIC values. Flucytosine levels in the abdominal fluid are comparable to serum levels and within MIC ranges.     

The effect of activated protein C on plasma cytokine levels in a porcine model of acute endotoxemia

Objective To assess the anti-inflammatory effects of recombinant human activated protein C (rhAPC) in a porcine model of acute endotoxemia. Design and setting Animal randomized controlled study at the Laboratory of Clinical Institute, Aarhus University Hospital. Subjects Eighteen female landrace pigs (30 kg). Interventions By pairwise randomization, pigs were given either LPS or LPS and rhAPC. Both groups received a stepwise increasing LPS infusion for 30 min; whereafter the infusion continued at a lower rate (300 min LPS in both groups). The LPS+rhAPC group received rhAPC (100 μg/kg per hour) 15 min before the LPS infusion began and throughout the trial period. Results While rhAPC showed no modifying effects on peak plasma levels of pro- or anti-inflammatory cytokines (TNF-α, IL-6, IL-8, IL-10), TNF-α and IL-10 peaked significantly later in the rhAPC-treated animals. The profibrinolytic effects of rhAPC were confirmed by decreased plasminogen activator inhibitor 1 levels, while no differences were found in other coagulation markers, hemodynamic, metabolic, or leukocyte data between the two groups. Conclusions We found no significant effect of rhAPC on plasma levels of either pro- or anti-inflammatory cytokines in this porcine model of acute endotoxemia. However, TNF-α and IL-10 peaked significantly later in the rhAPC-treated animals.     

Medication safety: just a label away

IN PERIOPERATIVE SETTINGS, medications are removed from manufacturers' identifying containers; therefore, scrub personnel should label medications placed on the sterile field.COMPLIANCE WITH MEDICATION labeling practices with the use of both blank and preprinted labels was tested in the OR at a Houston, Texas, hospital.SCRUB PERSONNEL WERE more likely to label medications and medication-delivery devices when preprinted medication labels were provided.DATA OBTAINED FROM this project influenced the hospital's management team to supply preprinted labels for all procedures to improve safety for surgical patients.     

Five-year clinical effectiveness of a two-step self-etching adhesive

PURPOSE: The purpose of this prospective randomized controlled clinical study was to evaluate the clinical performance of a "mild" two-step self-etching adhesive, Clearfil SE, in Class V restorations after 5 years of clinical functioning. MATERIALS AND METHODS: Twenty-nine patients received two or four restorations following two randomly assigned experimental protocols: (1) a mild self-etching adhesive (Clearfil SE, Kuraray) was applied following manufacturer's instructions on both enamel and dentin (C-SE non-etch); (2) similar application of Clearfil SE, but including prior selective acid-etching of the enamel cavity margins with 40% phosphoric acid (C-SE etch). Clearfil AP-X (Kuraray) was used as the restorative composite for all 100 restorations. The clinical effectiveness was recorded in terms of retention, marginal integrity, marginal discoloration, caries recurrence, postoperative sensitivity, and preservation of tooth vitality after 5 years of clinical service. The hypothesis tested was that selective acid etching of enamel with phosphoric acid improved retention, marginal integrity, and clinical microleakage of Class V restorations. RESULTS: Only one restoration of the C-SE non-etch group was lost at the 5-year recall. All other restorations were clinically acceptable. Marginal integrity deteriorated with time in both groups. The number of restorations with defect-free margins was significantly lower in the C-SE non-etch group (p = 0.0043). This latter group presented significantly more small incisal marginal defects on the enamel side (p = 0.0169). Superficial marginal discoloration increased in both groups, but was more pronounced in the C-SE non-etch group and was related to the higher frequency of small incisal marginal defects. CONCLUSION: The clinical effectiveness of the two-step self-etching adhesive Clearfil SE remained excellent after 5 years of clinical service. Additional etching of the enamel cavity margins resulted in an improved marginal adaptation on the enamel side; however, this was not critical for the overall clinical performance of the restorations.
