Diagnostic and Prognostic Significance of Carboxypeptidase A4 (CPA4) in Breast Cancer.

Recent research focused on prolonged survival has suggested that carboxypeptidase A4 (CPA4) plays a role in both tumor microenvironment formation and distant metastasis in cancer. In some patients, serum and expression (mRNA) levels of CPA4 have been found to be correlated with the aggressiveness and progression of the disease. Accordingly, we conducted a first study to investigate the diagnostic and prognostic significance of CPA4 in the case of breast cancer (BC), the most common form of malignancy in women. The study included a total of 50 patients with BC and 20 healthy women as the control group. The participants' serum CPA4 levels were determined by the ELISA test, and, for assessment of CPA4 mRNA, we used the PCR method. The serum CPA4 (p = 0.001) and CPA4 mRNA (p = 0.015) levels were found to be statistically significantly higher in the controls, compared to the patient group. When the results of patient group were statistically analyzed based on subgrouping by tumor characteristics, the measured CPA4 mRNA levels showed significant difference with respect to the molecular subtype (p = 0.006), pN status (p = 0.023), and pathological stage (p = 0.039), while the serum CPA4 measurements differed significantly in terms of pathological type only (p = 0.024). We conclude that CPA4 is diagnostically and prognostically not futile when used in combination with the other considerations and measurements in breast cancer.

Ethical conflicts in the treatment of fasting Muslim patients with diabetes during Ramadan.

BACKGROUND: For an effective treatment of patients, quality-assured safe implementation of drug therapy is indispensable. Fasting during Ramadan, an essential religious practice for Muslims, affects Muslim diabetics' drug use in a number of different ways. OBJECTIVES: Ethical problems arising from fasting during the month of Ramadan for practicing Muslim patients are being discussed on the basis of extant research literature. Relevant conflicts of interest originating in this situation are being analysed from an ethical perspective. MATERIAL AND METHODS: A number of databases have been searched systematically in view of the stated objectives to identify relevant studies. Starting point for this review are the following questions: What information is available regarding the fasting behaviour of Muslim diabetics during Ramadan? What kind of ethical problems can be identified in the context of this religious practice? RESULTS: The present review established a number of problems concerning medication adherence and drug use of practising Muslim diabetics during Ramadan, notably insufficient compliance, reduced frequency of consultations with their doctor, and inadequate, not sufficiently goal-oriented doctor-patient conversations about fasting. CONCLUSIONS: Deficiencies in medical as well as religious knowledge about fasting in Ramadan and a lack of sensitivity have been found among Muslim patients as well as among doctors. Compliance management and drug use in this area can be improved by effective, goal-oriented action plans and projects through which linguistic and cultural barriers can be addressed.

Nurse-focused ethical solutions to problems in organ transplantation.

Technological developments in recent years have brought about a rapid increase in the number and variety of organ transplants, leading to problems in finding enough organs to meet the need. Organ transplantation has also become a particularly significant issue in medical ethics, especially regarding the question of how and from whom organs are procured. Many methods have been tried in order to solve these problems and discussed from an ethical perspective. This study investigates the Spanish, Belgian and Iranian approaches to solving the organ procurement problem. The Spanish model, which is based on persuading patients and their relatives, is ethically less problematic and is also an improved version of the model applied in Turkey. This study argues that an ideal solution can be found without disregarding ethical rules. In particular, nurses can contribute by helping to run the system more efficiently. The principal aim of this article is to demonstrate the contribution of nurses to solving the current organ procurement problem in Turkey and offer some reflections on what can be done to improve the efficiency of the system.

Ethical aspects of human embryonic stem cell research in the islamic world: positions and reflections.

Rapid technological developments in human embryonic stem cell research are holding promises of future new medical treatment for a range of currently incurable chronic diseases. At the same time, stem cell research using human embryos raises radically new, previously unimaginable ethical issues posing a dramatic challenge to humankind. By analysing the discourses on these ethical issues we can show that the cultural values and religious convictions of all stakeholders involved play a decisive role in formulating ethical positions. In the Islamic world, too, stem cell research using human embryos provokes new discussions about the moral status of the embryo according to Islamic ethical norms. In our paper we describe the theological and philosophical criteria used in this debate and discuss some ethical positions vis-à-vis embryonic stem cell research formulated in the Islamic world, including official regulations existing in some Muslim countries. While most of the existing literature in this field is primarily descriptive, the present paper endeavours to examine not only the arguments and their historical conditions as such; in addition, we will for the first time provide a critical reflection on the methodology underlying commonly held positions. In our view, this reflection is of paramount importance in establishing a straightforward constructive dialogue between different cultures and academic disciplines.
