The routine application of oxygen to patients who are near death is not supported. The n-of-1 trial of oxygen in clinical practice is appropriate in the face of hypoxemic respiratory distress.

The second study involves a randomized trial of 20 subjects with a neuropathic pain diagnosis. We will offer three 20-minute VR sessions and assess change in and duration of impact on pain scores. We will also assess the impact of the three VR sessions on depression, anxiety, self-efficacy and catastrophizing.(513) The relationship between reminiscence, depressive symptoms, physical activity and pain

Background: African American women are more likely to experience preterm birth compared with White women. Social factors such as neighborhood disorder and experiences of racial discrimination, which disproportionately affect African American women, may partially explain these disparities. Purpose: The purpose of this study was to examine pregnant African American women's perceptions of neighborhood disorder, racial discrimination, and psychological distress and whether these concepts were viewed as influences on birth outcomes. Study Design and Methods: Using a mixed-methods approach, seven pregnant African American women completed questionnaires including scales for neighborhood disorder (Ross Neighborhood Disorder Scale), racial discrimination (Experiences of Discrimination), and psychological distress (Center for Epidemiological Studies Depression Scale; Psychological General Well-Being Index). All constructs were also assessed by semistructured interviews. Within- and across-case analyses were conducted to compare agreement and discordance between the data sources for each construct and to note patterns in the data. Results: The qualitative interviews provided data about women's experiences that were not captured by questionnaires alone. All of the women disclosed concerns about neighborhood conditions, experiences of discrimination, and psychological distress either reported on the questionnaires, during the qualitative interviews, or both. The mixed-methods approach provided a rich source of data that brought into focus the depth of the perceptions around these constructs. Clinical Implications: Maternal–child nurses should assess perceptions of neighborhood environment, racial discrimination, and psychological distress, as these factors may increase the risk for adverse pregnancy and birth outcomes.
