The Educational Value of Outpatient Consultation-Liaison Rotations: A White Paper From the Academy of Consultation-Liaison Psychiatry Residency Education Subcommittee.

BACKGROUND: As mental health services in outpatient medical clinics expand, psychiatrists must be trained to practice in these settings. OBJECTIVES: The Academy of Consultation-Liaison Psychiatry residency education subcommittee convened a writing group with the goal of summarizing the current evidence about outpatient consultation-liaison psychiatry (CLP) training and providing a framework for CLP educators who are interested in developing outpatient CLP rotations within their programs. METHOD: MEDLINE (via PubMed), Embase, and PsycINFO (via OVID) were reviewed each from inception to December 2019, for psychiatric CLP services in ambulatory settings that involved residents or fellows. The CLP education guidelines were reviewed for recommendations relevant to outpatient CLP. We also searched MedEd portal for published curriculums relevant to CLP. The group held 2 conferences to reach consensus about recommendations in setting up outpatient CLP rotations. RESULTS: Seventeen articles, 3 Academy of Consultation-Liaison Psychiatry-supported guidelines, and 8 online didactic resources were identified as directly reporting on the organization and/or impact of an outpatient CLP rotation. These manuscripts indicated that residents found outpatient CLP rotations effective and relevant to their future careers. However, the literature provided few recommendations for establishing formal outpatient CLP training experiences. CONCLUSIONS: Outpatient CLP rotations offer multiple benefits for trainees, including exposure to specific clinical scenarios and therapeutic interventions applicable only in the outpatient setting, increased continuity of care, and the unique experience of providing liaison and education to non-mental health providers. The article outlines recommendations and examples for developing outpatient CLP rotations which CLP educators can incorporate in their programs.

Exascale applications: skin in the game.

As noted in Wikipedia, skin in the game refers to having 'incurred risk by being involved in achieving a goal', where 'skin is a synecdoche for the person involved, and game is the metaphor for actions on the field of play under discussion'. For exascale applications under development in the US Department of Energy Exascale Computing Project, nothing could be more apt, with the skin being exascale applications and the game being delivering comprehensive science-based computational applications that effectively exploit exascale high-performance computing technologies to provide breakthrough modelling and simulation and data science solutions. These solutions will yield high-confidence insights and answers to the most critical problems and challenges for the USA in scientific discovery, national security, energy assurance, economic competitiveness and advanced healthcare. This article is part of a discussion meeting issue 'Numerical algorithms for high-performance computational science'.

Time domain diffuse correlation spectroscopy: modeling the effects of laser coherence length and instrument response function.

Diffuse correlation spectroscopy (DCS) is an optical technique that non-invasively quantifies an index of blood flow (BFi) by measuring the temporal autocorrelation function of the intensity fluctuations of light diffusely remitted from the tissue. Traditional DCS measurements use continuous wave (CW) lasers with coherence lengths longer than the photon path lengths in the sample to ensure that the diffusely remitted light is coherent and generates a speckle pattern. Recently, we proposed time domain DCS (TD-DCS) to allow measurements of the speckle fluctuations for specific path lengths of light through the tissue, which has the distinct advantage of permitting an analysis of selected long path lengths of light to improve the depth sensitivity of the measurement. However, compared to CW-DCS, factors including the instrument response function (IRF), the detection gate width, and the finite coherence length need to be considered in the model analysis of the experimental data. Here we present a TD-DCS model describing how the intensity autocorrelation functions measured for different path lengths of light depend on the coherence length, pulse width of the laser, detection gate width, IRF, BFi, and optical properties of the scattering sample. Predictions of the model are compared with experimental results using a homogeneous liquid phantom sample that mimics human tissue optical properties. The BFis obtained from the TD-DCS model for different path lengths of light agree with the BFi obtained from CW-DCS measurements, while the standard simplified model underestimates the BFi by a factor of ∼2. This Letter establishes the theoretical foundation of the TD-DCS technique and provides guidance for future BFi measurements in tissue.

Women With Mental Illness Seeking Assisted Reproduction Considerations in Ethical Candidate Selection.

PURPOSE OF REVIEW: This review aims to provide guidance to clinicians facing requests for assisted reproduction from women with mental illness. RECENT FINDINGS: The paper explores the clinical and safety aspects of initiating fertility treatment in this context, including the use of psychotropic medication and the risk of untreated psychiatric mood or psychotic disorders. It also presents the ethical considerations involved in candidate selection, including treating similar cases equitably to avoid biased decisions based solely on "gut-feelings," respect for women's reproductive autonomy, and an effort to protect patients and prospective fetuses/children from harm by employing optimal strategies regarding medication and psychosocial support. Clinicians ought to be informed regarding recent evidence related to the safety and efficacy of psychopharmacologic treatment of women during pregnancy and the post-partum. They should also carry out a thoughtful ethical analysis to ensure minimal violation of women's reproductive autonomy.

Diagnosis and Treatment of Anxiety in the Aging Woman.

The peri- and postmenopausal periods represent a window of vulnerability for emergence of anxiety symptoms and disorders in the life cycle of adult women. Compared to depression, anxiety symptoms and disorders remain largely unexplored during this phase of a woman's life, despite the significant impact on quality of life if not diagnosed and treated. Here, we review the literature to present our current understanding of the epidemiology, causal factors, diagnosis, and treatment of anxiety in the aging woman.

Gamete Donor Consent and Human Embryonic Stem Cell Research.

There is a lack of consensus on whether the derivation and use of human embryonic stem cells (hESCs) from embryos remaining after infertility treatment morally require the informed consent of third-party gamete donors who contributed to the creation of the embryos. The principal guidelines for oversight and funding of hESC research in the United States make minimal or no demands for consent from gamete donors. In this article, I consider the arguments supporting and opposing gamete donor consent for hESC research and embryo research more broadly. I argue that it is not morally permissible to use leftover embryos in research without the informed consent of gamete donors, and that we should place restrictions on the use of existing hESC lines that may have been derived without informed consent. While the standard argument for this position relies on an appeal to gamete donors' interest in controlling what happens with their genetic material, I identify shortcomings with the standard approach and seek instead to locate the deeper moral foundations for gamete donor consent in rights to bodily integrity.

Assessing decision-making capacity: a primer for the development of hospital practice guidelines.

Decision making capacity (DMC) is a fundamental concept grounding the principle of respect for autonomy and the practice of obtaining informed consent. DMC must be determined and documented every time a patient undergoes a hospital procedure and for routine care when there is reason to believe decision making ability is compromised. In this paper we explore a path toward ethically informed development and implementation of a hospital policy related to DMC assessment. We begin with a review of the context of DMC assessment before discussing some considerations relevant to policy creation by healthcare ethics committees. The discussion concludes in a presentation of a typology of capacity assessment policies, which draws upon a sampling of currently used hospital policies to illustrate relevant ethical considerations.

Attitudes towards euthanasia and assisted suicide: a comparison between psychiatrists and other physicians.

Euthanasia and physician assisted-suicide are terms used to describe the process in which a doctor of a sick or disabled individual engages in an activity which directly or indirectly leads to their death. This behavior is engaged by the healthcare provider based on their humanistic desire to end suffering and pain. The psychiatrist's involvement may be requested in several distinct situations including evaluation of patient capacity when an appeal for euthanasia is requested on grounds of terminal somatic illness or when the patient is requesting euthanasia due to mental suffering. We compare attitudes of 49 psychiatrists towards euthanasia and assisted suicide with a group of 54 other physicians by means of a questionnaire describing different patients, who either requested physician-assisted suicide or in whom euthanasia as a treatment option was considered, followed by a set of questions relating to euthanasia implementation. When controlled for religious practice, psychiatrists expressed more conservative views regarding euthanasia than did physicians from other medical specialties. Similarly female physicians and orthodox physicians indicated more conservative views. Differences may be due to factors inherent in subspecialty education. We suggest that in light of the unique complexity and context of patient euthanasia requests, based on their training and professional expertise psychiatrists are well suited to take a prominent role in evaluating such requests to die and making a decision as to the relative importance of competing variables.

CMS final rule requires NPI submission for Medicare and Medicaid provider enrollments and orders.

Despite the recent debate in the U.S. Supreme Court regarding the constitutionality of the health care reform act, CMS published a final rule related to several provisions from the Affordable Care Act (the Act).

The mobile nucleoporin Nup2p and chromatin-bound Prp20p function in endogenous NPC-mediated transcriptional control.

Nuclear pore complexes (NPCs) govern macromolecular transport between the nucleus and cytoplasm and serve as key positional markers within the nucleus. Several protein components of yeast NPCs have been implicated in the epigenetic control of gene expression. Among these, Nup2p is unique as it transiently associates with NPCs and, when artificially tethered to DNA, can prevent the spread of transcriptional activation or repression between flanking genes, a function termed boundary activity. To understand this function of Nup2p, we investigated the interactions of Nup2p with other proteins and with DNA using immunopurifications coupled with mass spectrometry and microarray analyses. These data combined with functional assays of boundary activity and epigenetic variegation suggest that Nup2p and the Ran guanylyl-nucleotide exchange factor, Prp20p, interact at specific chromatin regions and enable the NPC to play an active role in chromatin organization by facilitating the transition of chromatin between activity states.

The cultural context model: how does it facilitate couples' therapeutic change?

This study examines how therapeutic change in couples is facilitated in the Cultural Context Model based on the model's identified family processes: critical consciousness, empowerment, and accountability. Participants included four female therapists and three couples who sought treatment voluntarily, two heterosexual couples, and one lesbian couple with diverse class and ethnic backgrounds who had spent at least 12 months receiving services at the Institute for Family Services and who were compliant with treatment. Videotaped sessions were analyzed by coding descriptive data using a constant comparative analysis method. An analysis of therapeutic interventions and clients' changes showed that the model works in four realms: conversational, behavioral, ritual, and community building.

Informed consent to tissue donation: policies and practice.

Nearly 10 years ago, the tissue industry's informed consent practices with donor families in the United States were criticized. In response, the industry, along with the Inspector General of the Department of Health and Human Services, suggested elements to be included in the informed consent process. This study examines which of these elements were present in the informed consent documents of 45 (78%) of the nation's 58 Organ Procurement Organizations (OPOs). Some elements, such as involvement of for-profit companies, were present in almost all. Others, such as labeling tissue as a gift from donor families, never were. The authors conclude that the time is ripe for reexamination of the informed consent process with an eye to meaningful consent that promotes the benefits of tissue transplantation and at the same time protects the rights and interests of donor families; can be realistically implemented; and, maintains the trust of the American public.

Portable System for Time-Domain Diffuse Correlation Spectroscopy.

We introduce a portable system for clinical studies based on time-domain diffuse correlation spectroscopy (DCS). After evaluating different lasers and detectors, the final system is based on a pulsed laser with about 550 ps pulsewidth, a coherence length of 38 mm, and two types of single-photon avalanche diodes (SPAD). The higher efficiency of the red-enhanced SPAD maximizes detection of the collected light, increasing the signal-to-noise ratio, while the better timing response of the CMOS SPAD optimizes the selection of late photons and increases spatial resolution. We discuss component selection and performance, and we present a full characterization of the system, measurement stability, a phantom-based validation study, and preliminary in vivo results collected from the forearms and the foreheads of four healthy subjects. With this system, we are able to resolve blood flow changes 1 cm below the skin surface with improved depth sensitivity and spatial resolution with respect to continuous wave DCS.

Real-Time Single-Walled Carbon Nanotube-Based Fluorescence Imaging Improves Survival after Debulking Surgery in an Ovarian Cancer Model.

Improved cytoreductive surgery for advanced stage ovarian cancer (OC) represents a critical challenge in the treatment of the disease. Optimal debulking reaching no evidence of macroscopic disease is the primary surgical end point with a demonstrated survival advantage. Targeted molecule-based fluorescence imaging offers complete tumor resection down to the microscopic scale. We used a custom-built reflectance/fluorescence imaging system with an orthotopic OC mouse model to both quantify tumor detectability and evaluate the effect of fluorescence image-guided surgery on post-operative survival. The contrast agent is an intraperitoneal injectable nanomolecular probe, composed of single-walled carbon nanotubes, coupled to an M13 bacteriophage carrying a modified peptide binding to the SPARC protein, an extracellular protein overexpressed in OC. The imaging system is capable of detecting a second near-infrared window fluorescence (1000-1700 nm) and can display real-time video imagery to guide intraoperative tumor debulking. We observed high microscopic tumor detection with a pixel-limited resolution of 200 µm. Moreover, in a survival-surgery orthotopic OC mouse model, we demonstrated an increased survival benefit for animals treated with fluorescence image-guided surgical resection compared to standard surgery.

Neuronal gene expression correlates of Parkinson's disease with dementia.

Dementia is a common disabling complication in patients with Parkinson's disease (PD). The underlying molecular causes of Parkinson's disease with dementia (PDD) are poorly understood. To identify candidate genes and molecular pathways involved in PDD, we have performed whole genome expression profiling of susceptible cortical neuronal populations. Results show significant differences in expression of 162 genes (P < 0.01) between PD patients who are cognitively normal (PD-CogNL) and controls. In contrast, there were 556 genes (P < 0.01) significantly altered in PDD compared to either healthy controls or to PD-CogNL cases. These results are consistent with increased cortical pathology in PDD relative to PD-CogNL and identify underlying molecular changes associated with the increased pathology of PDD. Lastly, we have identified expression differences in 69 genes in PD cortical neurons that occur before the onset of dementia and that are exacerbated upon the development of dementia, suggesting that they may be relevant presymptomatic contributors to the onset of dementia in PD. These results provide new insights into the cortical molecular changes associated with PDD and provide a highly useful reference database for researchers interested in PDD.
