While the essence of nursing has long been whole person (body, mind, and spirit) and whole system-focused, in reality the contemporary practice of nursing in many settings around the globe has become increasingly fragmented and de-stabilized. Nursing shortages in many parts of the world are significant, and hierarchies and bureaucracies often remove nurses from the point of care, be that the bedside, home, or clinic, replacing them with less skilled workers and filling their time with documentation and other administrative tasks. Integrative nursing is a framework for providing whole person/whole system care that is relationship-based and person-centered and focuses on improving the health and wellbeing of caregivers as well as those they serve. It is aligned with what is being called the “triple aim” in the United States—an effort focused on improving the patient experience (quality and satisfaction), improving the health of populations, and reducing the cost of care. The principles of integrative nursing offer clear and specific guidance that can shape and impact patient care in all clinical settings.
We currently face a myriad of grand global challenges in fields such as poverty, the environment, education, science, and medicine. However, our current means of dealing with such challenges has fallen short, and ingenious solutions are required to overcome the inherent resistance to progress toward ameliorating such difficulties. Here, we highlight the promises and challenges of international collaboration in achieving success toward these trials. We note prior successes in fields such as education, medicine, science, and environmental issues made to date, yet at the same time we do note deficiencies and shortcomings in these efforts. Hence, the notion of international collaboration should be strengthened and encouraged by governments, non-profit organizations, and others moving forward using creative means to bring talented teams together to tackle these challenges across the globe.
On May 28, 2014, colleagues from the Mayo Clinic visited Rambam Health Care Campus to gather and exchange ideas and knowledge. American and Israeli caregivers and scientists shared with each other the daily challenges of their practice in many and varied settings. This issue is dedicated to the presentations given and the collaborative efforts we are building as a result of that visit. We hope this issue will serve as an example of the fruitfulness of international collaboration to enhance and propagate medical knowledge worldwide.
Essential monoclonal gammopathy is usually an asymptomatic condition, the characteristics of which have been defined over approximately 70 years of study. It has a known population-attributable risk of undergoing clonal evolution to a progressive, symptomatic B-cell neoplasm. In a very small fraction of patients, the monoclonal immunoglobulin has biophysical characteristics that can lead to tissue deposition syndrome (e.g. Fanconi renal syndrome) or, by chance, have characteristics of an autoantibody that may inactivate critical proteins (e.g. acquired von Willebrand disease). In this report, we describe the very uncommon forms of ocular injury that may accompany essential monoclonal gammopathy, which include crystalline keratopathy, crystal-storing histiocytosis, hypercupremic keratopathy, and maculopathy. The first three syndromes result from uncommon physicochemical alterations of the monoclonal immunoglobulin that favor crystallization or exaggerated copper binding. The last-mentioned syndrome is of uncertain pathogenesis. These syndromes may result in decreased visual acuity. These ocular findings may lead, also, to the diagnosis of monoclonal gammopathy.
Background: Postural tachycardia syndrome (POTS) is a common form of chronic orthostatic intolerance. The remarkable increase in heart rate (HR) upon standing is the hallmark of this syndrome. Treatment of POTS patients is challenging and includes drugs that slow the HR. Ivabradine is a selective If channel blocker designed to slow the HR, as an anti-anginal agent. In view of its ability to slow the HR, we posited that ivabradine may be an ideal medication for treating POTS patients. This report provides the results of an investigation in which we studied ivabradine’s effect on the hemodynamics and sympathovagal balance in POTS patients.
Methods: An open-label trial, without a placebo control, was performed in eight patients with POTS of two years’ standing. Characterization of symptoms, hemodynamics, autonomic function tests, and HR and blood pressure (BP) variability were determined while patients were in a supine position and during a 20-minute head-up tilt before and after a single oral dose of 7.5 mg ivabradine.
Results: Ivabradine slowed the HR of POTS patients at rest by 4±1 bpm (P<0.05). During a 5-minute head-up tilt, the HR decreased from 118±4 bpm to 101±5 bpm (P<0.01). Ivabradine did not affect the BP when patients were at rest in a supine position or in head-up tilt position. Cardiovascular vagal and sympathetic tone, extrapolated from the time and frequency domains of the HR and BP variability, were also not affected by ivabradine.
Conclusions: Ivabradine is an effective drug for slowing the HR of POTS patients at rest and during tilting, without producing significant adverse effects. Moreover, ivabradine exerts its effects without influencing the sympathovagal balance.
This brief introduction is followed by a published version of my Nobel Laureate lecture, re-published herein with the kind permission of the Nobel Foundation. Much has happened since my original research, for which that prize was awarded. Hence, I am pleased to offer a few thoughts about the future of my research and its possible impact on humankind.
Although the original work on nuclear transfer and reprogramming was done over half a century ago, advances continue to be made. In particular the Takahashi and Yamanaka induced pluripotent stem cells (iPS) procedure has opened up the field of cell replacement to a great extent. Now, more recently, further advances make this whole field come closer to actual usefulness for humans. Recently, in the UK, the government approved the use of mitochondrial replacement therapy to avoid the problems associated with genetically defective mitochondria in certain women. Although the House of Commons (members of Parliament) and the House of Lords had to debate and discuss whether to allow this kind of human therapy, I was very pleased to find that both bodies approved this procedure. This means that a patient can choose to make use of the procedure; it does not in any way force an individual to have a procedure that they are not comfortable with. In my view, this is a great advance in respect to giving patients a choice about the treatment they receive. I am told that the UK is the first country in the world to approve mitochondrial replacement therapy.
Now that the Clustered Regularly Interspaced Short Palindromic Repeat (CRISPr) technology is being widely used and works well, one can foresee that there will be those who wish to use this technology to make genetic changes to humans. For example, if a human has a gene that makes it susceptible to infection or any other disorder, the removal of that gene might give such a person immunity from that disease. If this gene deletion is done within the germ line, the genetic change will be inherited. However, one can imagine that various people will strongly object and say that this technology should not be allowed. I would very much hope that various regulatory bodies, governments, etc. will allow the choice to remain with the individual. I can see no argument for such bodies to make a law that removes any choice whatsoever by an individual.
The number needed to treat (NNT) is a simple measure of a treatment’s impact, increasingly reported in randomized trials and observational studies. It has been found to be incorrectly calculated in several studies involving varying follow-up times. We discuss the NNT in these contexts and illustrate the concept using several published studies. The computation of the NNT is founded on the cumulative incidence of the outcome. Instead, several published studies use simple proportions that do not account for varying follow-up times, or use incidence rates per person-time. We show how these approaches can lead to erroneous values of the NNT and misleading interpretations. For example, a trial of 3,845 very elderly hypertensives randomized to a diuretic or placebo reported a NNT of 94 treated for 2 years to prevent one stroke, though the correct approach results in a NNT of 63. We also note that meta-analyses involve trials of differing lengths, but often report a single NNT. For example a meta-analysis of 22 trials of the anticholinergic tiotropium in chronic obstructive pulmonary disease reported a NNT of 16 patients “over one year,” even if the trials varied in duration from 3 to 48 months, with the more specifically computed NNTs varying widely from 72, 15, and 250 for the 3-month, 12-month, and 48-month trials, respectively. Finally, we describe the value of the NNT in assessing benefit–risk, such as low-dose aspirin use in secondary prevention, where prevention of mortality was assessed against the risk of gastrointestinal bleeding. As the “number needed to treat” becomes increasingly used in the comparative effectiveness and safety of therapies, its accurate estimation and interpretation become crucial to avoid distorting clinical, economic, and public health decisions.
Feelings of guilt have tormented Holocaust survivors, ranging from immediately after the liberation to later in life, for shorter or longer periods, and persisting for some throughout their entire post-war lives. Descriptions of the guilt experienced by survivors of the Nazi camps occupy an impressive amount of literature: “Why me?” was the question, when a younger and more able family member perished; “Why me?” when more productive members of the community perished; “Why me?” when a million and a half children were deprived of their lives. Many found the answer by retelling their stories, witnesses of what happened. This type of guilt is much different from the recently described phenomenon of survivor syndrome, namely the secondary guilt felt by Nazi-persecuted Jewish writers. Despite successes in all aspects of their life, these writers developed a self-incriminating guilt due to their perceived inadequacy of communicating, particularly in light of the resurging anti-Semitism worldwide. This paper deals with the survival and suicides of Nazi-persecuted Jewish writers and offers a possible explanation for their late self-destructive acts.
Medicine is developing through biomedical technology and innovations. The goal of any innovation in medicine is to improve patient care. Exponential growth in technology has led to the unprecedented growth of medical technology over the last 50 years. Clinician-scientists need to understand the complexity of the innovation process, from concept to product release, when working to bring new clinical solutions to the bedside. Hence, an overview of the innovation process is provided herein. The process involves an invention designed to solve an unmet need, followed by prototype design and optimization, animal studies, pilot and pivotal studies, and regulatory approval. The post-marketing strategy relative to funding, along with analysis of cost benefit, is a critical component for the adoption of new technologies. Examples of the road to innovation are provided, based on the experience with development of the transcatheter aortic valve. Finally, ideas are presented to contribute to the further development of this worldwide trend in innovation.
Background: Following the announcement of actress Angelina Jolie’s prophylactic bilateral mastectomies and subsequent prophylactic oophorectomy, there has been a dramatic increase in interest in BRCA testing and prophylactic surgery.
Objective: To review current medical literature on the benefits of prophylactic mastectomy and oophorectomy among BRCA-positive women and its permissibility under Jewish law.
Results: Recent literature suggests that in BRCA-positive women who undergo prophylactic oophorectomy the risk of dying of breast cancer is reduced by 90%, the risk of dying of ovarian cancer is reduced by 95%, and the risk of dying of any cause is reduced by 77%. The risk of breast cancer is further reduced by prophylactic mastectomy. Prophylactic oophorectomy and prophylactic mastectomy pose several challenges within Jewish law that call into question the permissibility of surgery, including mutilation of a healthy organ, termination of fertility, self-wounding, and castration. A growing number of Jewish legal scholars have found grounds to permit prophylactic surgery among BRCA carriers, with some even obligating prophylactic mastectomy and oophorectomy.
Conclusion: Current data suggest a significant reduction in mortality from prophylactic mastectomy and oophorectomy in BRCA carriers. While mutilation of healthy organs is intrinsically forbidden in Jewish law, the ability to preserve human life may contravene and even mandate prophylactic surgery.
