Mitochondrial replacement therapy (MRT), also called nuclear genome transfer and mitochondrial donation, is a new technique that can be used to prevent the transmission of mitochondrial DNA diseases. Apart from the United Kingdom, the first country to approve MRT in 2015, Australia became the second country with a clear regulatory path for the clinical applications of this technique in 2021. The rapidly evolving clinical landscape of MRT makes the elaboration and evaluation of the responsible use of this technology a pressing (...) matter. As jurisdictions with less strict or non-existent reproductive laws are continuing to use MRT in the clinical context, the need to address the underlying ethical issues surrounding MRT’s clinical translation is fundamental.

Since their discovery over two decades ago, the molecular and cellular functions of the NIPSNAP family of proteins (NIPSNAPs) have remained elusive until recently. NIPSNAPs interact with a variety of mitochondrial and cytoplasmic proteins. They have been implicated in multiple cellular processes and associated with different physiologic and pathologic conditions, including pain transmission, Parkinson's disease, and cancer. Recent evidence demonstrated a direct role for NIPSNAP1 and NIPSNAP2 proteins in regulation of mitophagy, a process that is critical for cellular health and (...) maintenance. Importantly, NIPSNAPs contain a 110 amino acid domain that is evolutionary conserved from mammals to bacteria. However, the molecular function of the conserved NIPSNAP domain and its potential role in mitophagy have not been explored. It stands to reason that the highly conserved NIPSNAP domain interacts with a substrate that is ubiquitously present across all species and can perhaps act as a sensor for mitochondrial health.

Background The increasing prevalence of moral distress in the stressful environment of the intensive care unit (ICU) provides grounds for nursing error and endangers patients’ health, safety, and even life. One of the most important reasons for this distress is the treatment team’s second victim syndrome (SVS), especially nurses, following errors in the treatment system. Objectives The present study aimed to determine the relationship between moral distress and SVS in ICUs. Research design This cross-sectional study involved a sample size of (...) 96 ICU nurses working in hospitals affiliated with Tehran University of Medical Sciences, Iran, in the 2021–2022 period, who were selected via a simple random sampling method. Data were collected using the Demographic Questionnaire, the second victim experience and support tool (SVEST) and Moral Distress Scale-Revised (MDS-R). Descriptive statistics (percentage, frequency, mean, and SD) and analytical tests (Spearman correlation coefficient test, independent t-test, and ANOVA) were employed for data analysis. Participants and research context This study used a sample size of 96 intensive care unit nurses working in hospitals affiliated to Tehran University of Medical Sciences selected by simple random sampling. Ethical considerations The study obtained research ethics approval, and all participants were informed of the voluntary and anonymous nature of their participation. Findings The results showed that 59.4% of nurses suffered a low level of moral distress, and 40.6% suffered from a moderate level of moral distress. The SVS score of 86.5% of the nurses was moderate. There was no significant and direct correlation between moral distress and SVS in nurses; however, there was a significant and inverse correlation between the moral distress intensity and SVS ( p = 0.011). Conclusion Despite no significant correlation between moral distress and SVS, these variables were at moderate levels. Accordingly, it is suggested to provide a proper ground for expressing morally stressful situations, counseling and training strategies to deal with moral distress, creating support resources for those suffering from SVS, and implementing empowerment programs.

In the fast-evolving field of genomic medicine, genomic sequencing is still more commonly performed in research contexts. Large amounts of data are routinely generated in research, producing both p...

Studies on end-of-life care reveal different practices regarding withholding and/or withdrawing life-sustaining treatments between countries and regions. Available data about physicians’ practices regarding end-of-life care in ICUs in Egypt is scarce. This study aimed to investigate physicians’ attitudes toward end-of-life care and the reported practice in adult ICUs in Ain Shams University Hospitals, Cairo, Egypt. 100 physicians currently working in several ICU settings in Ain Shams University Hospitals were included. A self-administered questionnaire was used for collection of data. Most of (...) the participants agreed to implementation of “do not resuscitate” orders and applying pre-written DNR orders, while only 13% almost always/often order DNR for terminally-ill patients. 52% of the participants agreed to usefulness of limiting life-sustaining therapy in some cases, but they expressed fear of legal consequences. 47% found withholding life-sustaining treatment is more ethical than its withdrawal. 16% almost always/often withheld further active treatment but continued current ones while only 6% almost always/often withdrew active therapy for terminally-ill patients. The absence of legislation and guidelines for end-of-life care in ICUs at Ain Shams University Hospitals was the main influential factor for the dissociation between participants’ attitudes and their practices. Therefore, development of a consensus for end-of-life care in ICUs in Egypt is mandatory. Also, training of physicians in ICUs on effective communication with patients’ families and surrogates is important for planning of limitation of life-sustaining treatments. (shrink)
