Moral self-concept and moral sensitivity in Iranian nurses.

Nurses are often faced with serious situations that require high levels of legal and ethical knowledge, and should therefore be sensitive to the moral issues in their profession in the decision making process. Some studies have investigated nurses' moral self-concept as an effective factor in moral sensitivity, but there is not sufficient evidence to support this. The purpose of this study was to determine the correlation between moral sensitivity and moral self-concept in nurses employed in the teaching hospitals in Zahedan, Iran. This cross-sectional descriptive study aimed to study the relationship between moral self-concept and moral sensitivity in nurses employed in the teaching hospitals affiliated with Zahedan University of Medical Sciences. Chang's Moral Self-Concept Questionnaire and Lutzen's Moral Sensitivity Questionnaire were used for data collection. Data analysis was performed using SPSS software version 17. A total of 188 nurses participated in this study. The results showed that there was a positive and significant relationship between moral self-concept and moral sensitivity (P < 0.05). Based on our findings, an individual's attention to moral issues can lead to greater sensitivity and result in morally responsible behavior at the time of decision making. Consequently, promotion of moral self-concept through personal effort or education can increase moral sensitivity, which in turn leads to behavioral manifestations of ethical knowledge.

A needle free system for cervical lymphatic mapping and sentinel node biopsy in oral squamous cell carcinoma.

The techniques of lymphatic mapping and sentinel node biopsy are finding increasing utility in the management of the loco-regional lymphatics in many areas of oncology. Our unit is currently investigating their feasibility in relation to the management of the clinically node negative neck in oral squamous cell carcinoma. In order to reduce patient discomfort, and to remove the possibility of sharps injury, particularly in the high-risk patient, we report the use of a needle free device for the intra-oral delivery of the radiopharmaceutical. We believe that this is the first report using such a device in the oral cavity for the purpose of lymphoscintigraphy, and that it has significant advantages over the conventional hypodermic needle in certain patient groups.

Cancer multidisciplinary team meetings: evidence, challenges, and the role of clinical decision support technology.

Multidisciplinary team (MDT) model in cancer care was introduced and endorsed to ensure that care delivery is consistent with the best available evidence. Over the last few years, regular MDT meetings have become a standard practice in oncology and gained the status of the key decision-making forum for patient management. Despite the fact that cancer MDT meetings are well accepted by clinicians, concerns are raised over the paucity of good-quality evidence on their overall impact. There are also concerns over lack of the appropriate support for this important but overburdened decision-making platform. The growing acceptance by clinical community of the health information technology in recent years has created new opportunities and possibilities of using advanced clinical decision support (CDS) systems to realise full potential of cancer MDT meetings. In this paper, we present targeted summary of the available evidence on the impact of cancer MDT meetings, discuss the reported challenges, and explore the role that a CDS technology could play in addressing some of these challenges.

Three-dimensional time-resolved optical mammography of the uncompressed breast.

Optical tomography is being developed as a means of detecting and specifying disease in the adult female breast. We present a series of clinical three-dimensional optical images obtained with a 32-channel time-resolved system and a liquid-coupled interface. Patients place their breasts in a hemispherical cup to which sources and detectors are coupled, and the remaining space is filled with a highly scattering fluid. A cohort of 38 patients has been scanned, with a variety of benign and malignant lesions. Images show that hypervascularization associated with tumors provides very high contrast due to increased absorption by hemoglobin. Only half of the fibroadenomas scanned could be observed, but of those that could be detected, all but one revealed an apparent increase in blood volume and a decrease in scatter and oxygen saturation.
