Xing-Da Ju, Jing Xu, Zhong Sheng Sun
The CRISPR (clustered regularly interspaced short palindromic repeat)-Cas (CRISPR--associated protein) system, a prokaryotic RNA-based adaptive immune system against viral infection, is emerging as a powerful genome editing tool in broad research areas. To further improve and expand its functionality, various CRISPR delivery strategies have been tested and optimized, and key CRISPR system components such as Cas protein have been engineered with different purposes. Benefiting from more in-depth understanding and further development of CRISPR, versatile CRISPR-based platforms for genome editing have been rapidly developed to advance investigations in biology and biomedicine...

Shortly after the Presidential Commission for the Study of Bioethical Issues was constituted in 2010 and days before the commission members were to join a conference call to discuss possible topics for their deliberation, Craig Venter held a press conference announcing that his lab had created a synthetic chromosome for a species of mycoplasma and had inserted this genetic material into organisms of another species of mycoplasma (the genes of which had been deactivated), transforming the host species into the donor species...

In 2015, a flourish of "alarums and excursions" by the scientific community propelled CRISPR/Cas9 and other new gene-editing techniques into public attention. At issue were two kinds of potential gene-editing experiments in humans: those making inheritable germ-line modifications and those designed to enhance human traits beyond what is necessary for health and healing. The scientific consensus seemed to be that while research to develop safe and effective human gene editing should continue, society's moral uncertainties about these two kinds of experiments needed to be better resolved before clinical trials of either type should be attempted...

REVIEW
Paul S Appelbaum, Shawna Benston
PURPOSE OF REVIEW: Genetic testing for mental illness is likely to become increasingly prevalent as the science behind it is refined. This article identifies anticipated ethical challenges for patients, psychiatrists, and genetic counselors and makes recommendations for addressing them. RECENT FINDINGS: Many of the ethical challenges of psychiatric genetic testing are likely to stem from failures to comprehend the nature and implications of test results. Recent studies have identified gaps in the knowledge base of psychiatrists and genetic counselors, which limit their abilities to provide patients with appropriate education...

BACKGROUND: Tiered formularies, in which patients pay copays or coinsurance out-of-pocket (OOP), are used to manage costs and encourage more efficient health care resource use. Formulary tiers are typically based on the cost of treatment rather than the medical appropriateness for the patient. Cost sharing may have unintended consequences on treatment adherence and health outcomes. Use of higher-cost, higher-tier medications can be due to a variety of factors, including unsuccessful treatment because of lack of efficacy or side effects, patient clinical or genetic characteristics, patient preferences to avoid potential side effects, or patient preferences based on the route of administration...

REVIEW
Omay Lee, Mary Porteous
Genetic testing is increasingly important for investigating suspected inherited neurological conditions. A genetic diagnosis can have a huge impact on patients and also their families. It is important for neurologists to appreciate the presymptomatic and prenatal testing options available to patients and their at-risk relatives once a genetic disorder is diagnosed. Asymptomatic family members can experience considerable psychological distress from the knowledge that they might have inherited a neurodegenerative condition...

The human papillomavirus (HPV) vaccine has been linked to a number of serious adverse reactions. The range of symptoms is diverse and they develop in a multi-layered manner over an extended period of time. The argument for the safety and effectiveness of the HPV vaccine overlooks the following flaws: (i) no consideration is given to the genetic basis of autoimmune diseases, and arguments that do not take this into account cannot assure the safety of the vaccine; (ii) the immune evasion mechanisms of HPV, which require the HPV vaccine to maintain an extraordinarily high antibody level for a long period of time for it to be effective, are disregarded; and (iii) the limitations of effectiveness of the vaccine...

Advances in genomics often lead healthcare professionals (HCPs) to learn new information, e.g., about reinterpreted variants that could have clinical significance for patients seen previously. A question arises of whether HCPs should recontact these former patients. We present some findings interrogating the views of patients with a rare or undiagnosed condition about how such recontacting might be organised ethically and practically. Forty-one interviews with patients were analysed thematically. Participants suggested a 'joint venture' model in which efforts to recontact are shared with HCPs...

Allen Porter
Transhumanism is a "technoprogressive" socio-political and intellectual movement that advocates for the use of technology in order to transform the human organism radically, with the ultimate goal of becoming "posthuman." To this end, transhumanists focus on and encourage the use of new and emerging technologies, such as genetic engineering and brain-machine interfaces. In support of their vision for humanity, and as a way of reassuring those "bioconservatives" who may balk at the radical nature of that vision, transhumanists claim common ground with a number of esteemed thinkers and traditions, from the ancient philosophy of Plato and Aristotle to the postmodern philosophy of Nietzsche...

Acinetobacter baumannii is one of the most antibiotic-resistant pathogens in clinical medicine, and extensively drug-resistant (XDR) strains are commonly isolated from infected patients. Such XDR strains are already resistant to traditional selectable genetic markers, limiting the ability to conduct pathogenesis research by genetic disruption. Optimization of selectable markers is therefore critical for the advancement of fundamental molecular biology techniques to use in these strains. We screened 23 drugs that constitute a broad array of antibiotics spanning multiple drug classes against HUMC1, a highly virulent and XDR A...

The use of Whole-Genome Sequencing (WGS) in clinical settings has brought up a number of controversial scientific and ethical issues. The application of WGS is of particular relevance in neurology, as many conditions are difficult to diagnose. We conducted a worldwide, web-based survey to explore neurologists' views on the benefits of, and concerns regarding, the clinical use of WGS, as well as the resources necessary to implement it. Almost half of the 204 neurologists in the study treated mostly adult patients (48%), while the rest mainly children (37...

Genetic testing for personalizing diet and wellness programs is performed without extensive counseling that informs about the potential implications of knowing one's genotype status. Genetic counseling seems redundant for genes that impact the effect of diet on biomarkers such as cholesterol and blood pressure, but the same genes may have pleiotropic effects that cannot be ignored. A well-known example is the APOE gene, which is implicated in cholesterol regulation and is a major risk factor for Alzheimer's disease...

We surveyed hospital patients and clinicians to ascertain their attitudes to the establishment of a perioperative biobank for future genomics research, and whether the requirements for an opt-out approach to consent can be met. We enrolled hospital patients (n=187), patient spouse/family members (n=64), ethics committee members (n=14), and clinical staff (doctors and nurses [n=67]), and unspecified community members (n=10). They were asked to rate and describe their views on medical research and biobanking, the need for individual consent, and the importance of confidentiality...

In the last decade, genetic testing for cardiovascular disorders has become more and more relevant. Progress in molecular genetics has led to new opportunities for diagnostics, improved risk prediction and could lead to novel therapeutic approaches. Genetic diagnostic testing is relevant for both confirming a diagnosis as well as deciding on therapeutic consequences, if applicable. Furthermore, predictive testing in family members for specific cardiovascular diseases is now a standard procedure in holistic patient management...

Patient requests for transfer of embryos with genetic anomalies linked to serious health-affecting disorders detected in preimplantation testing are rare but do exist. This Opinion sets out the possible rationales for a provider's decision to assist or decline to assist in such transfers. The Committee concludes in most clinical cases it is ethically permissible to assist or decline to assist in transferring such embryos. In circumstances in which a child is highly likely to be born with a life-threatening condition that causes severe and early debility with no possibility of reasonable function, provider transfer of such embryos is ethically problematic and highly discouraged...

The ease and applicability of CRISPR/Cas9--a new and precise gene editing and reproductive technology--have garnered hype and heightened concern about its potential 'unprecedented and horrific consequences' and have led many scientific leaders to call for a moratorium on its research and use. CRISPR appears distinctly more controversial than previous technological innovations (genetic or otherwise), with a greater reach and speed of human treatment and enhancement; however, we have seen similarly inflated hopes and fears in response to other medical innovations for well over a century...

The majority of rare congenital disorders and syndromes have a genetic cause, but the diagnostic rate using standard workup is only around 50%. Whole exome and whole genome sequencing methods have improved the genetic diagnosis of syndromes during the latest few years. This article is a presentation of the current status of methods, results and ethical aspects, especially regarding incidental findings, of exome sequencing, which is now implemented in clinical diagnostics.

Effective community engagement is an important legal, ethical, and practical prerequisite for conducting field trials of genetically modified mosquitoes, because these studies can substantially impact communities and it is usually not possible to obtain informed consent from each community member. Researchers who are planning to conduct field trials should develop a robust community engagement strategy that meets widely recognized standards for seeking approval from the affected population, such as timeliness, consent, information sharing, transparency, understanding, responsiveness, mutual understanding, inclusiveness, and respectfulness...

Conducting research on the stem cell lines might bring some worthy good to public. Human Stem Cells (hSCs) research has provided opportunities for scientific progresses and new therapies, but some complex ethical matters should be noticed to ensure that stem cell research is carried out in an ethically appropriate manner. The aim of this review article is to discuss the importance of stem cell research, code of ethics for stem cell research in Iran and ethical recommendation. Generation of stem cells for research from human embryo or adult stem cells, saving, maintenance and using of them are the main ethical, legal and jurisprudence concerns in Iran...

STUDY QUESTION: What is the acceptability of using stem cell-based fertility treatments (SCFT) for different indications according to gynaecologists and the general public? SUMMARY ANSWER: The majority of gynaecologists and the general public accept SCFT for the indications female or male infertility in young heterosexual couples, and female infertility in single women and same-sex couples. WHAT IS KNOWN ALREADY: SCFT could result in genetic parenthood for intended parents with indications that cannot be treated using currently available methods, such as being in a same-sex relationship or female post-menopausal age...
