ABSTRACT
Polypharmacy and somatic symptom disorder (SSD) are common conditions clinicians see every day in practice. Polypharmacy is easy to identify and causation seems to be straightforward. However, SSD may not be so obvious and may be an underlying cause of the polypharmacy that may be more difficult to identify. Identifying SSD as a potential psychiatric cause for polypharmacy and understanding that adding more medications will not adequately resolve the patient's symptoms is important to prevent polypharmacy from being exacerbated.
ABSTRACT
A growing number of people living with HIV/AIDS are participating in HIV cure-related research at the end of life (EOL). Due to the novelty of EOL HIV cure-related research, there is a need to understand how their next-of-kin (NOK) perceive such research. We conducted in-depth interviews with NOK of the Last Gift study participants at the University of California, San Diego. The Last Gift study occurs in the context of the EOL and involves a full body donation. NOK completed two interviews: (1) shortly after the participants' enrollment in the study and (2) following death. We applied thematic analysis to analyze qualitative data. NOK included seven individuals (five males and two females), including two spouses, one ex-partner, one sister, a grandmother/grandfather, and a close friend. Thematic analysis revealed five key themes: (1) NOK viewed the Last Gift program in a positive light and had an accurate overall understanding of the study; (2) NOK identified factors that motivated participants to donate their body to science; (3) NOK identified benefits of the Last Gift program for both the donors and themselves; (4) NOK did not perceive any physical risks or decisional regrets of study but wanted to minimize psychosocial impacts and ensure the dignity of participants at all times; and (5) NOK noted elements that remained essential to the successful implementation of EOL HIV cure-related research, such as early involvement and clear communication. Our study uniquely contributes to increased understanding and knowledge of what is important from the point of view of supportive NOK to ensure successful implementation of EOL HIV cure-related research. More research will be needed to understand perspectives of less supportive NOK.

BACKGROUND: The U.S. National Institute of Allergies and Infectious Diseases (NIAID) and the National Institute of Mental Health (NIMH) have a new research priority: inclusion of terminally ill persons living with HIV (PLWHIV) in HIV cure-related research. For example, the Last Gift is a clinical research study at the University of California San Diego (UCSD) for PLWHIV who have a terminal illness, with a prognosis of less than 6 months. DISCUSSION: As end-of-life (EOL) HIV cure research is relatively new, the scientific community has a timely opportunity to examine the related ethical challenges. Following an extensive review of the EOL and HIV cure research ethics literature, combined with deliberation from various stakeholders (biomedical researchers, PLWHIV, bioethicists, and socio-behavioral scientists) and our experience with the Last Gift study to date, we outline considerations to ensure that such research with terminally ill PLWHIV remains ethical, focusing on five topics: 1) protecting autonomy through informed consent, 2) avoiding exploitation and fostering altruism, 3) maintaining a favorable benefits/risks balance, 4) safeguarding against vulnerability through patient-participant centeredness, and 5) ensuring the acceptance of next-of-kin/loved ones and community stakeholders. CONCLUSION: EOL HIV cure-related research can be performed ethically and effectively by anticipating key issues that may arise. While not unique to the fields of EOL or HIV cure-related research, the considerations highlighted can help us support a new research approach. We must honor the lives of PLWHIV whose involvement in research can provide the knowledge needed to achieve the dream of making HIV infection curable.

PURPOSE: To demonstrate the use of phase-variance optical coherence tomography (PV-OCT) angiography for detection of pigment epithelial detachment (PED) vascularization in age-related macular degeneration (AMD). PATIENTS AND METHODS: Patients with PEDs and exudative AMD were evaluated by the Retina Services at the University of California, Davis, and the University of California, San Francisco. Each subject underwent fluorescein angiography and structural optical coherence tomography (OCT). Phase-variance OCT analysis was used to create angiographic images of the retinal and choroidal vasculature. PV-OCT-generated B-scans were superimposed on structural OCT B-scans to allow easy identification of perfused vascular structures. RESULTS: Three patients with vascularized PEDs were imaged with PV-OCT, and each was found to have a vascular signal extending from the choroid into the hyperreflective substance of the PED. Two patients who had no evidence of PED vascularization on fluorescein angiography did not have vascular signals within their PEDs on PV-OCT. CONCLUSION: Structural OCT and PV-OCT images can be combined to create composite B-scans that offer high-resolution views of the retinal tissue along with dynamic vascular visualization. This technique offers a fast, noninvasive method for detecting vascularization of PEDs in AMD and may aid in the early detection of neovascular disease.
ABSTRACT
BACKGROUND: Age-related changes in the first-order multifocal electroretinogram (mfERG) responses were measured for two different luminance levels (200 and 700 cd.m(-2)). The relative contribution of optical and neural factors to senescent change in response was evaluated. METHODS: Data were obtained from one eye of each of 71 normal phakic subjects, age 9-80 years. The mfERG responses were recorded with the 7" stimulus-refractor unit (EDI) and VERIS 4.3 using the following protocol: bipolar contact lens, 103 hexagons, consecutive stimulation with 200 and 700 cd.m(-2), pupils > or =6 mm, amplification of 10(5), filter cut-offs at 10 and 300 Hz. RESULTS: Age-correlated decreases in amplitude and response density and increases in P1 implicit time were found for both luminance levels. The mean response density (nV.deg(-2)) was higher for the 700 cd.m(-2) stimulus, but the rate of change with age was not significantly different from that obtained with the 200 cd.m(-2) stimulus. Implicit time was not significantly different for the two light levels, nor was the rate of change with age. The decrease in response density and the increase in implicit time with age were significant across all retinal regions, dividing the 50 deg stimulus into six concentric rings. Age-related change in response density was greatest for the central retina and decreased with increasing retinal eccentricity. CONCLUSION: Log mfERG response changes linearly as a function of age. Analyses of the effects of reduced ocular media transmission and increased stray light, along with ancillary data obtained from pseudophakes, imply that age-related changes in the mfERG are due to both optical and neural factors.
