Biometry study of foveal isoplanatic patch variation for adaptive optics retinal imaging.

The change in ocular wavefront aberrations with visual angle determines the isoplanatic patch, defined as the largest field of view over which diffraction-limited retinal imaging can be achieved. Here, we study how the isoplanatic patch at the foveal center varies across 32 schematic eyes, each individualized with optical biometry estimates of corneal and crystalline lens surface topography, assuming a homogeneous refractive index for the crystalline lens. The foveal isoplanatic patches were calculated using real ray tracing through 2, 4, 6 and 8 mm pupil diameters for wavelengths of 400-1200 nm, simulating five adaptive optics (AO) strategies.

Robotic Repair of Acute Traumatic Diaphragmatic Injury From an Abdominal Approach: A Case Report.

Traumatic diaphragmatic injury is a rare condition with a significant mortality risk and may cause a herniation of an intraperitoneal organ into the pleural space. In the acute phase, traumatic diaphragmatic hernia (TDH) may be repaired with laparotomy or thoracotomy and is often associated with multiple concurrent injuries. This case report highlights a rare clinical scenario of blunt traumatic DH in a 62-year-old male with approximately seven centimeters of stomach herniating into the left pleural space, repaired with minimally invasive surgery.

In their own words: Perspectives of IPV survivors on obtaining support within the healthcare system.

Background: Almost half of all women in the US experience intimate partner violence (IPV) in their lifetime. The US Preventive Services Task Force recommends IPV screening paired with intervention for women of reproductive age. We aim to understand clinical practices and policies that are beneficial, detrimental, or insufficient to support survivors of IPV in a safety-net healthcare system.

The Impact of Intimate Partner Violence on Homelessness and Returns to Housing: A Qualitative Analysis From the California Statewide Study of People Experiencing Homelessness.

Homelessness is a public health concern in California and throughout the United States. Intimate partner violence (IPV) is a risk factor for experiencing homelessness. Few studies have examined the interplay between IPV, homelessness, and housing.

"We Remember the Pain": A qualitative study of intergenerational trauma among older adults experiencing homelessness in the HOPE HOME study.

Rates of homelessness among adults aged 50 and over are rising. Common strategies for exiting homelessness rely on social and family support. However, intergenerational trauma may disrupt these social support networks and contribute to homelessness.

Climate change could negate U.S. forest ecosystem service benefits gained through reductions in nitrogen and sulfur deposition.

Climate change and atmospheric deposition of nitrogen (N) and sulfur (S) impact the health and productivity of forests. Here, we explored the potential impacts of these environmental stressors on ecosystem services provided by future forests in the contiguous U.S.

Recent Advances in Cancer Immunotherapy with a Focus on FDA-Approved Vaccines and Neoantigen-Based Vaccines.

Cancer immunotherapies refer to the concept of retraining the immune system to target malignant cells. Multiple immunotherapeutic options exist including immune modulating antibodies, immune stimulating cytokines, chimeric antigen receptor T cell therapy, and vaccines. Overall, this field has advanced rapidly as knowledge of the tumor microenvironment, immunological pathways, and biotechnology expands.

Allergies, body mass, and hospitalization due to arbovirus infection: A prospective surveillance study in Machala, Ecuador.

Dengue, chikungunya, and Zika are arboviruses that cause 390 million infections annually. Risk factors for hospitalization are poorly understood. Communities affected by these diseases have an escalating prevalence of allergies and obesity, which are linked to immune dysfunction.

Information on medication abortion provided by family planning clinics in California.

Objectives: To assess access to abortion pills offered by clinics providing state-funded family planning services in California.

Methods: We attempted to make two scripted calls to a 20% random sample of family planning clinics in California, stratified by county, as "secret shoppers" in 2020 and 2021.

Results: Clinic staff responded to 407 calls.

Adverse Childhood Experiences and Aging-Associated Functional Impairment in a National Sample of Older Community-Dwelling Adults.

Background: Prior research on the health implications of adverse childhood experiences (ACEs) has focused on early or midlife adults, not older adults who bear the greatest burden of health-related functional impairment.

Objective: To examine associations between ACEs, objectively measured physical mobility and cognitive impairment, and functional disability in older community-dwelling adults.

Design: Cross-sectional analysis.

Factors Associated with Military Sexual Trauma (MST) Disclosure During VA Screening Among Women Veterans.

Background: Capturing military sexual trauma (MST) exposure is critical for Veterans' health equity. For many, it improves access to VA services and allows for appropriate care.

Objective: Identify factors associated with nondisclosure of MST in VA screening among women.

Posttraumatic Stress Disorder (PTSD) as a Risk Factor for Cardiovascular Disease: Implications for Future Research and Clinical Care.

Purpose Of Review: Posttraumatic stress disorder (PTSD) may be an important risk factor for cardiovascular disease (CVD). We explore the literature linking PTSD to CVD, potential mechanisms, interventions, and clinical implications. We outline gaps in current literature and highlight necessary future research.

Veterans Health Administration Screening for Military Sexual Trauma May Not Capture Over Half of Cases Among Midlife Women Veterans.

Background: Approximately 1 in 3 women veterans endorse military sexual trauma (MST) during Veterans Health Administration (VHA) screening. Higher rates have been reported in anonymous surveys.

Objective: We compared MST identified by VHA screening to survey-reported MST within the same sample and identified participant characteristics associated with discordant responses.

Opportunities for improving provision of emergency contraception in California.

Objectives: To assess emergency contraception (EC) service provision by California's family planning clinics.

Study Design: We made 2 scripted calls to a random sample of 309 family planning clinics.

Results: We reached one hundred ninety-four clinics on 2 occasions, although only 183 (59%) could be reached with the information provided online by California's office of family planning.

The Association Between Interpersonal Violence and Unstable Housing Among Veterans.

Background: Despite programs to address housing for Veterans, they continue to be at high risk of unstable housing. Interpersonal violence is also highly prevalent among Veterans and may contribute to unstable housing. Our study aimed to determine whether interpersonal violence was associated with unstable housing among Veterans, and how this association was influenced by common co-occurring conditions such as substance use and mental illness.

Dissociation between Corneal and Cardiometabolic Changes in Response to a Time-Restricted Feeding of a High Fat Diet.

Mice fed a high fat diet (HFD) ab libitum show corneal dysregulation, as evidenced by decreased sensitivity and impaired wound healing. Time-restricted (TR) feeding can effectively mitigate the cardiometabolic effects of an HFD. To determine if TR feeding attenuates HFD-induced corneal dysregulation, this study evaluated 6-week-old C57BL/6 mice fed an ad libitum normal diet (ND), an ad libitum HFD, or a time-restricted (TR) HFD for 10 days.

Novel Foveal Features Associated With Vision Impairment in Multiple Sclerosis.

Purpose: To characterize scattering and hyperreflective features in the foveal avascular zone of people with multiple sclerosis (MS) using adaptive optics scanning laser ophthalmoscopy (AOSLO) and to evaluate their relationship with visual function and MS disease characteristics.

Methods: Twenty subjects with MS underwent confocal reflectance and non-confocal split-detection AOSLO foveal imaging. Peripapillary retinal nerve fiber layer thickness was measured using optic nerve optical coherence tomography.

Current Status of HIV-1 Vaccines.

HIV-1 infection and its progression to AIDS remains a significant global health challenge, particularly for low-income countries. Developing a vaccine to prevent HIV-1 infections has proven to be immensely challenging with complex biological acquisition and infection, unforeseen clinical trial disappointments, and funding issues. This paper discusses important landmarks of progress in HIV-1 vaccine development, various vaccine strategies, and clinical trials.

Platelet and Erythrocyte Extravasation across Inflamed Corneal Venules Depend on CD18, Neutrophils, and Mast Cell Degranulation.

Platelet extravasation during inflammation is under-appreciated. In wild-type (WT) mice, a central corneal epithelial abrasion initiates neutrophil (PMN) and platelet extravasation from peripheral limbal venules. The same injury in mice expressing low levels of the β-integrin, CD18 (CD18 mice) shows reduced platelet extravasation with PMN extravasation apparently unaffected.

Corneal dysfunction precedes the onset of hyperglycemia in a mouse model of diet-induced obesity.

Purpose: The purpose of this study was to use a mouse model of diet-induced obesity to determine if corneal dysfunction begins prior to the onset of sustained hyperglycemia and if the dysfunction is ameliorated by diet reversal.

Methods: Six-week-old male C57BL/6 mice were fed a high fat diet (HFD) or a normal diet (ND) for 5-15 weeks. Diet reversal (DiR) mice were fed a HFD for 5 weeks, followed by a ND for 5 or 10 weeks.

Serial block-face scanning electron microscopy reveals neuronal-epithelial cell fusion in the mouse cornea.

The cornea is the most highly innervated tissue in the body. It is generally accepted that corneal stromal nerves penetrate the epithelial basal lamina giving rise to intra-epithelial nerves. During the course of a study wherein we imaged corneal nerves in mice, we observed a novel neuronal-epithelial cell interaction whereby nerves approaching the epithelium in the cornea fused with basal epithelial cells, such that their plasma membranes were continuous and the neuronal axoplasm freely abutted the epithelial cytoplasm.
