Augmented reality for epilepsy surgery: Examining usability and efficacy in presurgical planning.

Objective: The aim of this paper was to visualize 3-dimensional (3-D) brain and electrode placement data for epilepsy surgery within an augmented reality (AR) environment using a wearable headset, with the ultimate goal of enhancing presurgical planning for epilepsy surgery and understanding the efficiency and utility of such a program in a clinical setting. The evaluation process for surgical intervention in epilepsy cases involves a series of extensive tests, including EEG, MRI, PET, SPECT, and fMRI. A second phase of assessment incorporates the placement of depth electrodes within the brain to record seizure activity.

Dissecting the Enterococcal Polysaccharide Antigen (EPA) structure to explore innate immune evasion and phage specificity.

Streptococci, Lactococci and Enterococci all produce L-rhamnose-containing cell wall polysaccharides which define Lancefield serotypes and represent promising candidates for the design of glycoconjugate vaccines. The L-rhamnose containing Enterococcal Polysaccharide Antigen (EPA), produced by the opportunistic pathogen Enterococcus faecalis, plays a critical role in normal growth, division, biofilm formation, antimicrobial resistance, phage susceptibility, and innate immune evasion. Despite the critical role of this polymer in E.

Hormonal Contraception and Risk of Cardiometabolic Disease in Women with HIV.

We sought to determine the association of hormonal contraception (HC) and cardiometabolic outcomes among women with human immunodeficiency virus (HIV). We included women with HIV aged 18-45 years in clinical care in the Southeastern United States between 1998 and 2018. Oral and injectable HC use was captured from medication records.

Environmental Injustice Is Associated With Poorer Asthma Outcomes in School-Age Children With Asthma in Metropolitan Atlanta, Georgia.

Background: Environmental justice mandates that no person suffers disproportionately from environmental exposures. The Environmental Justice Index (EJI) provides an estimate of the environmental burden for each census tract but has not yet been used in asthma populations.

Objective: We hypothesized that children from census tracts with high environmental injustice determined by the EJI would have a greater burden of asthma exacerbations, poorer asthma control, and poorer lung function over 12 months.

Knowledge and Attitudes on Contraception and Reproductive Health in Women With HIV.

Background: For reasons not fully explained to date, contraception usage among women with HIV remains low. The aim of our study was to understand attitudes toward and lifetime use of contraception among women with HIV.

Methods: We administered an anonymous, community-informed, voluntary survey to cisgender, English-speaking women with HIV (≥18 years of age) at a Southern urban HIV clinic.

Social determinants of health influence preschool and caregiver experiences during symptoms and exacerbations of wheezing.

Background: Social determinants of health have been inadequately studied in preschool children with wheezing and their caregivers but may influence the care received.

Objective: To evaluate the symptom and exacerbation experiences of wheezing preschool children and their caregivers, stratified by risk of social vulnerability, over 1 year of longitudinal follow-up.

Methods: A total of 79 caregivers and their preschool children with recurrent wheezing and at least 1 exacerbation in the previous year were stratified by a composite measure of social vulnerability into "low" (N = 19), "intermediate" (N = 27), and "high" (N = 33) risk groups.

Low Rates of Contraception Use in Women With Human Immunodeficiency Virus.

Background: Women with human immunodeficiency virus (WWH) have low rates of hormonal or long-acting contraceptive use. Few studies have described contraception use among WWH over time.

Methods: We examined contraception (including all forms of hormonal contraception, intrauterine devices, and bilateral tubal ligations) use among cisgender women aged 18-45 years in care at Vanderbilt's human immunodeficiency virus (HIV) clinic in Nashville, Tennessee, from 1998 through 2018.

The Impact of COVID-19 on the HIV Care Continuum in a Large Urban Southern Clinic.

Access to care is essential for people with HIV (PWH) but may have been affected during the COVID-19 pandemic. We conducted a retrospective cross-sectional study of adult PWH receiving care in a large southeastern comprehensive care clinic in the United States. Patients in care between January 1, 2017, and July 30, 2020, were included.

The illusion of a chest wall tumor: a case-report of sternal tuberculosis.

The incidence rate of tuberculosis in developed countries is low. The most common presentation of this disease is its pulmonary form but with the increasing use of immunosuppressive drugs, extra-pulmonary tuberculosis is re-emerging. Nevertheless, sternal bone involvement is uncommon.

Racism Runs Through It: Examining The Sexual And Reproductive Health Experience Of Black Women In The South.

Few studies have illustrated how racism influences Black women's use of reproductive health care services. This article presents findings of a collaborative study conducted by a research team and a reproductive justice organization to understand Black women's concerns with sexual and reproductive health services. The qualitative research was conducted with Black women living in Georgia and North Carolina, using a community-based participatory research approach.

An Innovative Biological Model for Ultrasound-Guided Central Venous Access Simulation.

Introduction: Simulation training is an increasingly used method to train medical students in the use of ultrasound guidance for vascular access positioning. Although very efficient for basic training, commercial simulators for vascular access do not reproduce real-life conditions. We developed a biological training model, using porcine liver, and compared it with an existing commercial model.

nNOS-expressing interneurons control basal and behaviorally evoked arterial dilation in somatosensory cortex of mice.

Cortical neural activity is coupled to local arterial diameter and blood flow. However, which neurons control the dynamics of cerebral arteries is not well understood. We dissected the cellular mechanisms controlling the basal diameter and evoked dilation in cortical arteries in awake, head-fixed mice.

Efavirenz Pharmacogenetics and Weight Gain Following Switch to Integrase Inhibitor-Containing Regimens.

Background: Unwanted weight gain affects some people living with human immunodeficiency virus (HIV) who are prescribed integrase strand transfer inhibitors (INSTIs). Mechanisms and risk factors are incompletely understood.

Methods: We utilized 2 cohorts to study pharmacogenetics of weight gain following switch from efavirenz- to INSTI-based regimens.

Anatomical basis and physiological role of cerebrospinal fluid transport through the murine cribriform plate.

Cerebrospinal fluid (CSF) flows through the brain, transporting chemical signals and removing waste. CSF production in the brain is balanced by a constant outflow of CSF, the anatomical basis of which is poorly understood. Here, we characterized the anatomy and physiological function of the CSF outflow pathway along the olfactory sensory nerves through the cribriform plate, and into the nasal epithelia.

Topical paromomycin for New World cutaneous leishmaniasis.

Background: Paromomycin-based topical treatments were shown to be effective in curing cutaneous leishmaniasis (CL) lesions caused by Leishmania major in Tunisia. Cure rates of an index lesion were approximately 80%. As a follow on, we conducted a similar Phase 3 trial in Panama to demonstrate the efficacy of these treatments against New World species.

Pharmacokinetics and pharmacodynamics of cytochrome P450 inhibitors for HIV treatment.

Drugs used in HIV treatment; all protease inhibitors, some non-nucleoside reverse transcriptase inhibitors, and pharmacoenhancers ritonavir and cobicistat can inhibit cytochrome P450 (CYP) enzymes. CYP inhibition can cause clinically significant drug-drug interactions (DDI), leading to increased drug exposure and potential toxicity. Areas covered: A complete understanding of pharmacodynamics and CYP-mediated DDI is crucial to prevent adverse side effects and to achieve optimal efficacy.

Neonatal rat age, sex and strain modify acute antioxidant response to ozone.

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death in the US and its impact continues to increase in women. Oxidant insults during critical periods of early life appear to increase risk of COPD through-out the life course. To better understand susceptibility to early life exposure to oxidant air pollutants we used Fisher (F344), Sprague-Dawley (SD) and Wistar (WIS) male and female neonatal rat pups to assess: (A) if strain (i.

Brief Report: Weight Gain in Persons With HIV Switched From Efavirenz-Based to Integrase Strand Transfer Inhibitor-Based Regimens.

Background: With the introduction of integrase strand transfer inhibitor (INSTI)-based antiretroviral therapy, persons living with HIV have a potent new treatment option. Recently, providers at our large treatment clinic noted weight gain in several patients who switched from efavirenz/tenofovir disoproxil fumarate/emtricitabine (EFV/TDF/FTC) to dolutegravir/abacavir/lamivudine (DTG/ABC/3TC). In this study, we evaluated weight change in patients with sustained virologic suppression who switched from EFV/TDF/FTC to an INSTI-containing regimen.
