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'.

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.

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.

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.

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.

Deep Brain Stimulation for Alzheimer's Disease: Ethical Challenges for Clinical Research.

Deep brain stimulation (DBS) is an invasive neuromodulation modality that has shown early promise as a novel treatment of Alzheimer's disease (AD). Further clinical research is warranted on the basis of positive results from animal and human studies, as well as the inadequacy of existing treatments in reducing the enormous medical and financial costs of untreated AD. Nevertheless, unique ethical challenges require particular attention to elements of subject enrollment and informed consent. Study protocols should specify robust assessment and regular monitoring of subject decision-making capacity to consent to trial participation. Investigators should also assess for and mitigate therapeutic misconception (the phenomenon whereby a research participant conflates the goals of research with those of clinical treatment) and ensure that all prospective trial participants have adequate post-trial access to treatment and DBS device maintenance. In the following discussion, each issue is summarized and followed by recommendations for proper ethical procedure. We conclude by assimilating relevant ethical considerations into a decision-making algorithm designed to aid future clinical investigators of DBS for AD with the task of ethical subject enrollment.

Diagnosing, Disclosing, and Documenting Borderline Personality Disorder: A Survey of Psychiatrists' Practices.

Borderline personality disorder (BPD) is a valid and reliable diagnosis with effective treatments. However, data suggest many patients remain unaware they carry the diagnosis, even when they are actively engaged in outpatient psychiatric treatment. The authors conducted a survey of 134 psychiatrists practicing in the United States to examine whether they had ever withheld and/or not documented their patients' BPD diagnosis. Fifty-seven percent indicated that at some point during their career they failed to disclose BPD; 37 percent said they had not documented the diagnosis. For those respondents with a history of not disclosing or documenting BPD, most agreed that either stigma or uncertainty of diagnosis played a role in their decisions. The findings highlight the need for clinical training programs to address these issues. The research also invites further research to identify other reasons why psychiatrists are hesitant to be fully open about the diagnosis of BPD.

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.

Tumor-to-tumor metastasis: report of two cases of renal cell carcinoma metastasizing to microcystic serous cystadenoma of the pancreas.

Metastatic cancer to the pancreas accounts for less than 2% of all pancreatic malignancies. In contrast to other metastatic tumors, renal cell carcinoma (RCC) has a propensity to metastasize as a solitary pancreatic lesion. While symptomatic patients may present with obstructive jaundice, abdominal pain, or gastrointestinal bleeding, the diagnosis of metastatic pancreatic involvement is often made in asymptomatic patients, during follow-up evaluation in the aftermath of an initial diagnosis of renal cell carcinoma. Microcystic serous cystadenoma of the pancreas is an uncommon pancreatic exocrine neoplasm that morphologically resembles conventional (clear cell) RCC, in so far as both tumors are characterized by neoplastic cells with clear cytoplasm, relatively uniform nuclei and scant associated tumor stroma. Herein, we report 2 immunohistochemically confirmed cases of unsuspected metastatic RCC to the pancreas, with the metastatic tumor in each case confined to a preexisting microcystic serous cystadenoma of the pancreas.

Pelvic floor muscle training in males: practical applications.

The pelvic floor muscles are vital to male genitourinary health. Pelvic floor muscle training may prove helpful in a variety of clinical circumstances: stress urinary incontinence that follows prostate surgery, overactive bladder, postvoid dribbling, erectile dysfunction, ejaculation issues including premature ejaculation, and pelvic pain due to levator muscle spasm.

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.
