A Psychoanalytic Qualitative Study of Subjective Life Experiences of Women With Breast Cancer

This article exemplifies research on the subjective life experiences of women with breast cancer, designed from a psychoanalytic perspective. Such research aims to reveal the subjective intrapsychic processes of women suffering from breast cancer, which can provide researchers and health care professionals with useful insight. Using Biographic narrative interpretative method, the study reveals some common denominators in the subjective life experiences of women with breast cancer. The study revealed that the subjects consider the diagnosis of breast cancer as one of the four main events in their lives. Even though these events are very different from each other, in terms of type and severity, the results indicate a common process in the way these life events are experienced by the participants. These results are relevant for health care practitioners in structuring their psychosocial support programs so as to better accommodate their patients' psychological needs

Pyranose oxidase and Pt-MnOx bionanocomposite electrode bridged by ionic liquid for biosensing applications

WOS: 000334753200017Present study reports the use of a glassy carbon electrode modified with manganese oxide decorated with platinum nanoparticles (Pt-MnOx/GCE) for electrocatalytic reduction of oxygen dissolved in buffer solution. The electrode exhibits better electrocatalytic activity toward oxygen reduction than bulk platinum due to larger surface area of manganese oxide which also prevents agglomeration of platinum nanoparticles. Best results were obtained with the electrode modified by cycling the potential in a range of -0.25-1.05 V for five times in a cell containing 1.0 mM K2PtCl6 and 0.1 M MnSO4 in 0.01 M H2SO4 solution. Then, the electrode developed was utilized as a biosensing platform for the monitoring of oxygen consumption due to the bie-catalytic activity of pyranose oxidase. In the pursuit of a stable and rapid response the biocomponent was bridged with an ionic liquid namely 1-butyl-3-methyl imidazolium hexaflourophosphate. Chronoamperometric measurement of oxygen at 0.2 V gave 0.010-0.100 mM linear range with a detection limit of 2.0 mu M and sensitivity of 6.1 nA mu M-1 under optimized conditions. In addition, ionic liquid provides a conductive environment which shortens the response time to 3 s for low concentrations. Overall results indicated that fabricated biosensor is a good candidate for automated systems. (C) 2014 Elsevier B.V.

Clinical Performance of Samfilcon A Contact Lenses in Intensive Digital Device Users: A Multicenter, Prospective Clinical Study

Introduction To evaluate patient satisfaction with samfilcon A contact lenses (CLs) in intensive digital device users with myopia and to compare patient satisfaction with samfilcon A lenses to prior experience with senofilcon A or lotrafilcon B CLs. Methods This was a comparative, prospective, national study conducted at 14 centers in Turkey. Subjects were adults aged 18 and 45 years with myopia (range -0.25 D to -6.00 D) who spend a minimum of 3 hours viewing digital devices (e.g., computer, smartphone). A subgroup of patients were habitual lens wearers (senofilcon A or lotrafilcon B lens wear for at least 6 months prior to enrollment). The primary assessment was patient satisfaction with samfilcon A lenses (0-100 Likert scale). Secondary assessments included patient satisfaction with samfilcon A lenses compared to patients' habitual lenses, investigator satisfaction with samfilcon A lenses and investigator-evaluated slit lamp examination findings. Results Samfilcon A lenses were given high overall ratings from both patients and investigators, with a low incidence of ocular symptoms. Overall, patients were highly satisfied with samfilcon A lenses for comfort, vision and overall performance, and stated that they would consider wearing these lenses in the future. Among habitual senofilcon A or lotrafilcon B lens wearers, samfilcon A lenses were rated significantly better than the habitual lenses in regard to comfort, vision and overall performance. Investigator assessments were also highly favorable, both at initial fit and after 4 weeks of follow-up, with no significant findings noted on slit lamp examination. Conclusion Samfilcon A lenses were rated highly by investigators in regard to fit, handling and slit lamp findings, and by novice and habitual lens wearers in regard to comfort, vision and overall performance. These results support the use of samfilcon A lenses among digital device users who seek day-long comfort and good visual acuity
