Recognition Theory in Nurse/Patient Relationships: The contribution of Gillian Rose

Recognition theory attempts to conceptualize interpersonal relationships and their normative political implications. British social philosopher Gillian Rose developed her own version of recognition rooted in the work of Georg Hegel. This article applies Rose's theory of recognition to care, arguing that its emphasis on lack of identity, the dynamic process of recognition and the existential risks involved accurately describes the relationship between nurse and patient. Rose's version is compared to both contemporary notions of the interpersonal in healthcare literature, other forms of recognition theory and Emmanuel Levinas's vision of intersubjective relationships, a traditional philosophical basis for nursing care. In each case, I will argue that Rosean recognition is a fuller, more complex and ultimately more satisfying view of the relationships involved.

The effects of Rosa damascene aromatherapy on anxiety and sleep quality in burn patients: A randomized clinical trial

Introduction and objectiveSleep disorders and anxiety are common problems in burn patients, and aromatherapy is a common complementary treatment in medicine. The aim of this study was to determine the effects of aromatherapy with the inhalation of rose essential oil on anxiety and sleep quality in burn patients.Materials and methodsThis randomized controlled clinical trial was performed on 60 patients admitted to the Valiasr Hospital B in Arak from March 2021 to the end of July 2021. The patients were chosen by the convenience sampling method and then randomly divided into the intervention and control groups based on the block randomization method (six blocks). Aromatherapy along with the routine care was provided to the participants of the intervention group for three consecutive nights. These participants inhaled five drops of 40 % rose essential oil. The members of the control group also inhaled five drops of distilled water as a placebo. In both groups, anxiety and sleep quality were assessed using the St. Mary’s Hospital Sleep Quality Questionnaire (SMHSQ) and the Spielberger State-Trait Anxiety Inventory (STAI), respectively, before and after the intervention.ResultsThe sleep quality scores of the intervention and control groups after the intervention were 17.88 ± 2.04 and 26.11. 3.31, respectively, showing a statistically significant difference (P < 0.05). Our results also showed a statistically significant difference in the anxiety score between the intervention and control groups after aromatherapy (P < 0.05).ResultsRose essential oil aromatherapy reduced anxiety and improved sleep quality in burn patients, suggesting this approach as a useful complementary method along with other therapeutic measures in these patients.     

Cancer treatment using an optically inert Rose Bengal derivative combined with pulsed focused ultrasound

Pulsed high intensity focused ultrasound (HIFU) has been combined with a photo-insensitive Rose Bengal derivative (RB2) to provide a synergistic cytotoxicity requiring the presence of both ultrasonic cavitation and drug. In vitro tests have shown that a short treatment (less than 30 s) of pulsed HIFU with peak negative pressure > 7 MPa (~ 27 W acoustic power at 1.4 MHz) destroys > 95% of breast cancer cells MDA-MB-231 in suspension with > 10 μM of the compound. Neither the pulsed HIFU nor the RB2 compound was found to have any significant impact on the viability of the cells when used alone. Introducing an antioxidant (N-acetylcysteine) reduced the effectiveness of the treatment. In vivo tests using these same cells growing as a xenograft in nu/nu mice were also done. An ultrasound contrast agent (Optison) and lower frequency (1.0 MHz) was used to help initiate cavitation at the tumor site. We were able to demonstrate tumor regression with cavitation alone, however, addition of RB2 compound injected i.v. yielded a substantial synergistic improvement.

Influence of iron oxide nanoparticles (Fe3O4) on erythrocyte photohemolysis via photofrin and Rose Bengal sensitization

BackgroundIron oxide (Fe₃O₄) nanoparticles (IO-NP) were recently employed in medical applications as a diagnostic tool and drug carrier. Photofrin (PF) is a photosensitizer that clinically is used in Photodynamic therapy (PDT).Study designThe photosensitivity of PF and Rose Bengal (RB) mixed with (IO-NP) on red blood cells (RBCs) lysis was investigated. Second, Photohemolysis for post-irradiation (delayed) and during irradiation (continuous) with PF, RB and IO-NP combinations at different concentrations was investigated. Third, the photohemolysis rate, relative lysis steepness and power-concentration dependant parameter were evaluated by modeling and fitting the data using Gompertz function and power law.MethodsRBCs were isolated from healthy male human volunteer. Washed cells (7.86 × 10⁶ cells/mm³) were incubated with PF only or with IO-NP for 45 min at 37 °C then irradiated to a range of temperatures (4–41 °C). CPH results were recorded and evaluated using Gompertz function.ResultsThe relative steepness of the photohemolysis curves was approximately independent on light dose for delayed irradiation. The presence of IO-NP increases the rupturing time for 50% of the RBCs. Photohemolysis rate for delayed irradiation using the power law, led to 1.7 and 2.3 power dependence, respectively, for PF only and PF mixed with IO-NP. The power dependence of continuous irradiation measurements showed inverse proportionality for different concentrations of IO-NP combined with 2 μg/ml PF concentration and 1.5 μg/ml for RB concentration.ConclusionPhotosensitization of RBC with PF or RB mixed with IO-NP inhibited rupturing erythrocyte membrane and therefore a consideration should be taken against their combination in clinical applications.     

Blood pressure related echocardiographic changes in adolescents and young adults

In 1973, standardized blood pressure measurements were obtained in 837 high school students in Bourbon County, Kentucky, a rural county with a high prevalence of individuals with systemic hypertension. In 1978, follow-up measurements of blood pressure were performed in selected individuals who were in the high, intermediate, and low ranges of the initial sex-specific blood pressure distributions. Relative rank order of initial blood pressure measurements over the five-year period was maintained. The results of this population-based study provided an opportunity to evaluate the cardiac status in young adults with relatively high blood pressures maintained over five years. Standard m-mode echocardiographic examinations were, therefore, performed over five years. Standard m-mode echocardiographic examinations were, therefore, performed at the time of follow-up. In individuals in the low and intermediate ranges for systolic blood pressure, indices of ventricular hypertrophy were directly correlated with blood pressure level. Among individuals with higher values for systolic blood pressure, after adjusting for the effects of relative body size, indices of ventricular hypertrophy were not significantly different from those noted in the intermediate group. Indices of cardiac performance and estimated left ventricular systolic wall stress were, however, significantly elevated in this "high" blood pressure group. Early in the course of systemic hypertension increased wall stress, rather than hypertrophy, appears to be the primary cardiac manifestation of elevated systolic blood pressure.
