This manuscript describes how to classify nematodes using temporal far-field diffraction signatures. A single C. elegans is suspended in a water column inside an optical cuvette. A 632 nm continuous wave HeNe laser is directed through the cuvette using front surface mirrors. A significant distance of at least 20-30 cm traveled after the light passes through the cuvette ensures a useful far-field (Fraunhofer) diffraction pattern. The diffraction pattern changes in real time as the nematode swims within the laser beam...

OBJECTIVE: The amount of lipid delivered to patients varies considerably depending on the non-nutritional intake from sedation, and on the feeding solution. The aim of this study was to quantify the magnitude and proportion of lipids and energy provided from propofol sedation in intensive care unit (ICU) patients. METHODS: This was a retrospective analysis of prospectively collected data in consecutive patients admitted to the ICUs of two university hospitals. Inclusion criterion included an ICU stay >5 d...

Hiroki Makita, Gary Hastings
In all photosynthetic organisms, light energy is used to drive electrons from a donor chlorophyll species via a series of acceptors across a biological membrane. These light-induced electron-transfer processes display a remarkably high quantum efficiency, indicating a near-complete inhibition of unproductive charge recombination reactions. It has been suggested that unproductive charge recombination could be inhibited if the reaction occurs in the so-called inverted region. However, inverted-region electron transfer has never been demonstrated in any native photosynthetic system...

Johan Brännmark's article "Patients as Rights Holders," in this issue of the Hastings Center Report, squarely identifies some important problems with the way we in clinical practice conceive of our obligations to our patients. As a solution, he helpfully suggests augmenting our focus on autonomy and informed consent with a broader menu of considerations drawn from the literature on human rights. Respect for autonomy is, of course, one of the hallowed principles of bioethics. In our traditional understanding, our patients deserve our respect because they are capable of autonomous choice, and the way we demonstrate our respect is by seeking their informed consent for our care...

The lead article in this issue of the Hastings Center Report (July-August 2017) explores the ideas underpinning the Precision Medicine Initiative, the effort announced by President Obama in 2015 to promote the development of treatments adjusted to genetic and other variations. Authors Maya Sabatello and Paul Appelbaum hold that the effort works by appealing to a sense of collective identity and shared commitment-an understanding that they call the "PMI nation." But what are the moral implications of this idea? Sabatello and Appelbaum's question about the impact of an imagined community is an unusual way of exploring a set of values questions...

In this issue of the Hastings Center Report, Maya Sabatello and Paul Appelbaum explore the assumptions about community embedded in the U.S. Precision Medicine Initiative, which aims to recruit donor-partners who reflect the United States' racial and ethnic diversity. As Sabatello and Appelbaum discuss, the initiative is like other national biobanking efforts in bringing to life an imagined genetic community in need of critical attention, and given the public-private forms of partnership at the heart of the PMI, such efforts could become avenues to deepen existing inequalities rather than to alleviate them...

REVIEW
Andrew K Hastings, Erol Fikrig
Beginning in 2015, concern over a new global epidemic has spread in the media, governmental agencies, legislative bodies and the public at large. This newly emerging threat has been reported to cause symptoms ranging from mild fever, rash, and body aches, to severe birth defects and acute onset paralysis. The causative agent of this disease, Zika virus, is closely related to two other important human pathogens, dengue and West Nile Virus (WNV), but has some distinguishing features that has raised alarms from the scientific community...

In 2019, The Hastings Center will celebrate its fiftieth anniversary. It is more than a bit staggering to think how far we have come since 1969. When I floated the idea of a center on bioethics to my friend and neighbor, psychiatrist Willard Gaylin, at a Christmas party in 1968-even before the word "bioethics" was used-I had only the fuzziest idea of where that would take us. Neither Will nor I had run anything, nor did we know how to raise money to support an organization. We would and did learn how, but much of what we did in those early years was made up on the fly...

Anita Ho
In this issue of the Hastings Center Report, Joshua Rager and Peter Schwartz suggest using opioid treatment agreements as public health monitoring tools to inform patients about "the requirements entailed by undergoing opioid therapy," rather than as contractual agreements to alter patients' individual behavior or to benefit them directly. Because Rager and Schwartz's argument presents suspected OTA violations as a justification to stop providing opioids yet does not highlight the broader epistemic and systemic context within which clinicians prescribe these medications, their proposal may perpetuate a climate of distrust and stigmatization without correcting systemic factors that may have placed patients and others at risk in the first place...

This issue of the Hastings Center Report (May-June 2017) features a couple of interesting takes on the governance challenges of emerging technologies. In an essay on the National Academies of Science, Engineering, and Medicine report published this February on human germ-line gene editing, Eric Juengst, a philosopher at the University of North Carolina, argues that the NASEM committee did not manage to rethink the rules. Juengst reaches what he calls an "eccentric conclusion": "The committee's 2017 consensus report has been widely interpreted as 'opening the door' to inheritable human genetic modification and holding a line against enhancement interventions...

In this issue of the Hastings Center Report, Joshua Rager and Peter Schwartz reframe the justification for the use of opioid treatment agreements. Instead of documents used to define the roles and responsibilities of doctors and patients to one another in the course of opioid treatment for chronic pain and to describe the risks and benefits of therapy for the individual, OTAs are now proposed for use as "surveillance and monitoring" instruments. As such, they are specifically meant to disclose the risks of opioid therapy and to describe the other processes and tools used to monitor abuse and diversion of medications...

EQUiPPED is a multicomponent quality improvement initiative combining education, electronic clinical decision support, and individual provider feedback to influence prescribing and improve medication safety for older adults. The objective here was to evaluate the effectiveness and sustainability of EQUiPPED to reduce the use of potentially inappropriate medications (PIMs), as defined by the American Geriatrics Society 2012 Beers Criteria, prescribed to older Veterans at the time of emergency department (ED) discharge...

Jianjie Wang, Hugo Roncalver
As new applications of Schrödinger type inequalities appearing in Jiang (J. Inequal. Appl. 2016:247, 2016), we first investigate the existence and uniqueness of a Schrödingerean equilibrium. Next we propose a tritrophic Hastings-Powell model with two different Schrödingerean time delays. Finally, the stability and direction of the Schrödingerean Hopf bifurcation are also investigated by using the center manifold theorem and normal form theorem.

Søren Holm
In this issue of the Hastings Center Report, Moti Gorin, Steven Joffe, Neal Dickert, and Scott Halpern offer a comprehensive defense of the use of nudging techniques in the clinical context, with the aim of promoting the best interests of patients. Their argument is built on three important claims: Nudging is ubiquitous and inescapable in clinical choice situations, and there is no neutral way of informing patients about their treatment choices; many patients do not have authentic (preexisting) preferences concerning their treatment choices, and those that do can easily resist nudging; and, finally, since many people lack authentic preferences and those that do can still act on their preferences, nudging in the patients' best interest is justified...

At a time of fake news, hacks, leaks, and unverified reports, many people are unsure whom to believe. How can we communicate in ways that make individuals question their assumptions and learn? My colleagues at The Hastings Center and many journalists and scientists are grappling with this question and have, independently, reached the same first step: recognize that facts can't be fully understood without probing their connection to values. "Explaining the basics is important, of course, but we also need to diversify our approach to the coverage of science-particularly as it intersects with the matrix of cultural, religious, social, and political values of our readers," said an article in Undark, an online magazine of science journalism...

In this issue of the Hastings Center Report, Paul Christopher and colleagues describe a study of why prisoners choose to enroll in clinical research. The article represents an important methodological and policy contribution to the literature on prisoner participation in research and medical experimentation. Given the methodological and ethical debates to which this research seeks to make an empirical contribution, the careful manner in which the study was conducted and the transparency with which the authors describe the research is especially noteworthy...

We search for the rare flavor-changing neutral current process B^{+}→K^{+}τ^{+}τ^{-} using data from the BABAR experiment. The data sample, collected at the center-of-mass energy of the ϒ(4S) resonance, corresponds to a total integrated luminosity of 424  fb^{-1} and to 471×10^{6}  BB[over ¯] pairs. We reconstruct one B meson, produced in the ϒ(4S)→B^{+}B^{-} decay, in one of many hadronic decay modes and search for activity compatible with a B^{+}→K^{+}τ^{+}τ^{-} decay in the rest of the event...

Importance: Hispanics are the largest minority group in the United States and face a disproportionate burden of risk factors for cardiovascular disease (CVD) and low socioeconomic position. However, Hispanics paradoxically experience lower all-cause mortality rates compared with their non-Hispanic white (NHW) counterparts. This phenomenon has been largely observed in Mexicans, and whether this holds true for other Hispanic subgroups or whether these favorable trends persist over time remains unknown...

BACKGROUND: The effectiveness of specific systems changes to reduce DTN (door-to-needle) time has not been fully evaluated. We analyzed the impact of 4 specific DTN time reduction strategies implemented prospectively in a staggered fashion. METHODS AND RESULTS: The HASTE (Hurry Acute Stroke Treatment and Evaluation) project was implemented in 3 phases at a single academic medical center. In HASTE I (June 6, 2012 to June 5, 2013), baseline performance was analyzed...
