Othering is a process that identifies those that are thought to be different from oneself or the mainstream, and it can reinforce and reproduce positions of domination and subordination. Although there are theoretical and conceptual treatments of othering in the literature, researchers lack sufficient examples of othering practices that influence the interactions between patients and health care providers. The purpose of this study was to explore the interactions between health care providers and South Asian immigrant women to describe othering practices and their effects. Ethnographic methods were used involving in-depth interviews and focus group discussions. The analysis entailed identifying uses of othering and exploring the dynamics through which this process took place. Women shared stories of how discriminatory treatment was experienced. The interviews with health care professionals provided examples of how views of South Asian women shaped the way health care services were provided. Three forms of othering were found in informants' descriptions of their problematic health care encounters: essentializing explanations, culturalist explanations, and racializing explanations. Women's stories illustrated ways of coping and managing othering experiences. The analysis also revealed how individual interactions are influenced by the social and institutional contexts that create conditions for othering practices. To foster safe and effective health care interactions, those in power must continue to unmask othering practices and transform health care environments to support truly equitable health care.

Background: Blood pressure (BP) control in patients with diabetes mellitus is difficult to achieve and current patterns are suboptimal. Given increasing problems with access to primary care physicians, community pharmacists and nurses are well positioned to identify and observe these patients. This study aimed to determine the efficacy of a community-based multidisciplinary intervention on BP control in patients with diabetes mellitus.Methods: We performed a randomized controlled trial in 14 community pharmacies in Edmonton, Alberta, Canada, of patients with diabetes who had BPs higher than 130/80 mm Hg on 2 consecutive visits 2 weeks apart. Care from a pharmacist and nurse team included a wallet card with recorded BP measures, cardiovascular risk reduction education and counseling, a hypertension education pamphlet, referral to the patient's primary care physician for further assessment or management, a 1-page local opinion leader-endorsed evidence summary sent to the physician reinforcing the guideline recommendations for the treatment of hypertension and diabetes, and 4 follow-up visits throughout 6 months. Control-arm patients received a BP wallet card, a pamphlet on diabetes, general diabetes advice, and usual care by their physi-cian. The primary outcome measure was the difference in change in systolic BP between the 2 groups at 6 months.Results: A total of 227 eligible patients were randomized to intervention and control arms between May 5, 2005, and September 1, 2006. The mean (SD) patient age was 64.9 (12.1) years, 59.9% were male, and the mean (SD) baseline systolic/diastolic BP was 141.2 (13.9)/ 77.3 (8.9) mm Hg at baseline. The intervention group had an adjusted mean (SE) greater reduction in systolic BP at 6 months of 5.6 (2.1) mm Hg compared with controls (P =.008). In the subgroup of patients with a systolic BP greater than 160 mm Hg at baseline, BP was reduced by an adjusted mean (SE) of 24.1 (1.9) mm Hg more in intervention patients than in controls (PϽ.001). Conclusion:Even in patients who have diabetes and hypertension that are relatively well controlled, a pharmacist and nurse team-based intervention resulted in a clinically important improvement in BP.

Many phase II protective genes contain a cis-acting enhancer region known as the antioxidant response element (ARE). Increased expression of these genes contributes to the protection of cells from oxidative stress. Transgenic reporter mice were created that carry in their genome the core ARE coupled to the human placental alkaline phosphatase (hPAP) reporter gene. Primary cortical cultures derived from these mice were treated with tBHQ resulting in a dose-dependent increase in hPAP activity. Histochemical staining for hPAP activity was observed in both glia and neurons from tBHQ-treated cultures. The tBHQ-mediated increase in hPAP was not affected by the antioxidant glutathione monoethyl ester (GSHEE), whereas the increase in hPAP following DEM treatment was completely blocked by GSHEE. Pre-treatment of cultures with the PI3-kinase inhibitor LY 294002 demonstrated a dose-dependent decrease in tBHQ-induced hPAP activity. In addition, the tBHQ-mediated expression of ARE-driven genes in primary cortical cultures was blocked by LY 294002. Interestingly, basal expression of Nrf2 was also inhibited by LY 294002. We theorize that increased levels of genes controlled by the ARE are important for cellular protection against oxidative stress. These ARE-hPAP transgenic mice will be an important in vivo model for testing our hypothesis.

Background and Purpose-The replicability of the physical and mental component summary scores of the Short Form (SF)-36 has been established using the SF-12 in selected patient populations but has yet to be assessed in stroke patients.If the summary scores of the SF-12 are highly correlated with those of the SF-36, the benefits of using a shorter health-status measure may be realized without substantial loss of information or precision. Both self-reported and proxy assessments were evaluated for replicability. Methods-Intraclass correlation coefficients (ICCs) and linear regression were used to assess the ability of the SF-12 physical component summary (PCS-12) scores to predict PCS-36 scores and the SF-12 mental component summary (MCS-12) scores to predict MCS-36 scores. Multivariate regression was used to explore the relationship between SF-12 and SF-36 scores. Results-The MCS-12 and PCS-12 scores were strongly correlated with the corresponding SF-36 summary scores for surveys completed by proxy or self-report (ICCs ranged from 0.954 to 0.973). Regression analysis of the proxy assessments indicated that patient age was an important effect modifier in the relationship between MCS-12 and MCS-36 scores. Conclusions-The SF-12 reproduced SF-36 summary scores without substantial loss of information in stroke patients.Accordingly, the SF-12 can be used at the summary score level as a substitute for the SF-36 in stroke survivors capable of self-report. However, the mental health summary scores of proxy assessments are influenced by patient age, thereby limiting the replicability of the SF-36 by the SF-12 under these conditions.

If caring is to be retained as the "essence" of nursing, and if research in this area is to advance, then the various perspectives of caring must be clarified, the strengths and the limitations of these conceptualizations examined, and the applicability of caring as a concept and theory to the practice of nursing identified. Examination of the concept of caring resulted in the identification of five epistemological perspectives: caring as a human state, caring as a moral imperative or ideal, caring as an affect, caring as an interpersonal relationship, and caring as a nursing intervention. Two outcomes of caring were identified: caring as the subjective experience and as the physiologic responses in patients. The authors concluded that knowledge development related to caring in nursing is limited by the lack of refinement of caring theory, the lack of definitions of caring attributes, the neglect to examine caring from the dialectic perspective, and the focus of theorists and researchers on the nurse to the exclusion of the patient.

The evolution of phage resistance poses an inevitable threat to the efficacy of phage therapy. The strategic selection of phage combinations that impose high genetic barriers to resistance and/or high compensatory fitness costs may mitigate this threat. However, for such a strategy to be effective, the evolution of phage resistance must be sufficiently constrained to be consistent. In this study, we isolated lytic phages capable of infecting a modified Klebsiella pneumoniae clinical isolate and characterized a total of 57 phage-resistant mutants that evolved from their prolonged coculture in vitro. Single- and double-phage-resistant mutants were isolated from independently evolved replicate cocultures grown in broth or on plates. Among resistant isolates evolved against the same phage under the same conditions, mutations conferring resistance occurred in different genes, yet in each case, the putative functions of these genes clustered around the synthesis or assembly of specific cell surface structures. All resistant mutants demonstrated impaired phage adsorption, providing a strong indication that these cell surface structures functioned as phage receptors. Combinations of phages targeting different host receptors reduced the incidence of resistance, while, conversely, one three-phage cocktail containing two phages targeting the same receptor increased the incidence of resistance (relative to its two-phage, nonredundant receptor-targeting counterpart). Together, these data suggest that laboratory characterization of phage-resistant mutants is a useful tool to help optimize therapeutic phage selection and cocktail design. IMPORTANCE The therapeutic use of bacteriophage (phage) is garnering renewed interest in the setting of difficult-to-treat infections. Phage resistance is one major limitation of phage therapy; therefore, developing effective strategies to avert or lessen its impact is critical. Characterization of in vitro phage resistance may be an important first step in evaluating the relative likelihood with which phage-resistant populations emerge, the most likely phenotypes of resistant mutants, and the effect of certain phage cocktail combinations in increasing or decreasing the genetic barrier to resistance. If this information confers predictive power in vivo, then routine studies of phage-resistant mutants and their in vitro evolution should be a valuable means for improving the safety and efficacy of phage therapy in humans.
