OBJECTIVE:Demonstrate a successful laparoscopic removal of endometriosis from within the inguinal canal via a step-by-step video explanation, underscore the importance of pre-operative MRI imaging, and provide education on anatomy and surgical technique. DESIGN/METHODS:Video case presentation of a successful laparoscopic removal of endometriosis from within the inguinal canal. SUBJECTS/METHODS:A single patient with MRI imaging revealing endometriosis invasion into the inguinal canal and local vasculature. The patient included in this video gave consent for publication of the video and posting of the video online including social media, the journal website, scientific literature websites (such as PubMed, ScienceDirect, Scopus, etc.) and other applicable sites. EXPOSURE/METHODS:The patient's abdomen was entered and vasculature was identified to prevent major bleeding. Appropriate exposure was achieved by transecting the round ligament to provide a landmark for the inguinal canal. The endometriosis was identified and dissected off the external iliac vasculature and the abdominal wall using the squeeze technique. The endometriosis was then dissected out of the inguinal canal, off the femoral artery, and then removed from the abdomen. Post-operatively, the patient was started on norethindrone acetate to suppress any residual disease and prevent recurrence. MAIN OUTCOME MEASURE/METHODS:Patient's pain and quality of life post-operatively. RESULTS:The patient noted immediate pain relief in the recovery room. One year post-operatively, the patient continued to endorse pain relief and no signs of hernia. CONCLUSION/CONCLUSIONS:Inguinal canal endometriosis is of rare occurrence. It typically presents as a groin lump or pain that is worse with menstruation. As the endometriosis is in close proximity to the abdominal wall and local vasculature, MRI imaging, as well as general surgery and vascular surgery consultation, are necessary for proper surgical planning. These are difficult operations that require proper understanding of pelvic and inguinal canal anatomy.

OBJECTIVE/UNASSIGNED:The authors aimed to characterize the long-term psychiatric outcomes and their predictors among survivors of autoimmune encephalitis (AE). METHODS/UNASSIGNED:In this retrospective cohort study, patients diagnosed as having AE between 2008 and 2023 at two academic medical centers (in New York City and Toronto) completed the Mini International Neuropsychiatric Interview 7.0.2 (MINI) and Profile of Mood States (POMS-2) to assess long-term psychiatric outcomes. Clinical characteristics were assessed for potential predictors of psychiatric outcomes. Bivariate analyses and univariate logistic regressions were conducted to assess the relationship between the predictors and the primary outcome. RESULTS/UNASSIGNED:-methyl-d-aspartate (33%), anti-leucine-rich-glioma-inactivated 1 (24%), anti-glutamic acid decarboxylase 65 (14%), and antibody-negative encephalitis (29%). In total, 71% of participants who completed the MINI met criteria for a DSM-5 diagnosis, and 56% were diagnosed as having a mood disorder. Thirteen participants (31%) reported above-average total mood disturbance on the POMS-2. Mann-Whitney U tests revealed that participants diagnosed as having a mood disorder self-reported significantly higher levels of confusion and bewilderment (z=-2.04, p=0.04) and depression and dejection (z=-2.24, p=0.03) and lower levels of vigor and activity (z=-2.62, p=0.01). CONCLUSIONS/UNASSIGNED:AE survivors have a high prevalence of psychiatric comorbid conditions, with most being diagnosed as having a mood disorder and a significant proportion endorsing ongoing mood disturbance. Patients with a psychiatric history may benefit from closer psychiatric follow-up.

Seizures associated with low-grade tumors in pediatric patients can be drug resistant and associated with significant morbidity. There are several low-grade tumor types associated with epilepsy in this population with the majority localized to the temporal lobe and some extra-temporal locations (frontal, parietal, and occipital lobes). The primary treatment of low-grade epilepsy-associated tumors is surgical resection, though the surgical approach and the use of intraoperative techniques remain controversial. Newer treatments are under investigation as primary and/or adjunctive therapy, including non-invasive surgical options and gene-targeted therapy. A multimodal approach to treatment may improve long-term outcomes and quality of life.

Neuroanatomical changes to the cortex during adolescence have been well documented using MRI, revealing ongoing cortical thinning and volume loss. Recent advances in MRI hardware and biophysical models of tissue informed by diffusion MRI data hold promise for identifying the cellular changes driving these morphological observations. Using ultra-strong gradient MRI, this study quantifies cortical neurite and soma microstructure in typically developing youth. Across domain-specific networks, cortical neurite signal fraction, attributed to neuronal and glial processes, increases with age. The apparent soma radius, attributed to the apparent radius of glial and neuronal cell bodies, decreases with age. Analyses of two independent post-mortem datasets reveal that genes increasing in expression through adolescence are significantly enriched in cortical oligodendrocytes and Layer 5-6 neurons. In our study, we show spatial and temporal alignment of oligodendrocyte cell-type gene expression with neurite and soma microstructural changes, suggesting that ongoing cortical myelination processes drive adolescent cortical development.

BACKGROUND:Nursing documentation burden is a growing point of concern in the United States healthcare system. Documentation in the electronic health record (EHR) is a contributor to perceptions of burden. Efficiency tools like flowsheet macros are one development intended to ease the burden of documentation. OBJECTIVE:Evaluate if flowsheet macros, a documentation efficiency tool in the EHR that consolidates documentation into a single click, reduces the time spent in documentation activities and the EHR overall. METHODS:Nurses in the health system were encouraged to create and utilize flowsheet macros for their documentation. Flowsheet documentation and time in system data for nurses' first and last shift in the evaluation period was extracted from the EHR. Linear regression with control variables was utilized to understand if utilization of flowsheet macros for documentation reduced the time spent in flowsheets or the EHR. RESULTS:The results of linear regression showed a significant, negative relationship between flowsheet macros use and time in flowsheets (AOR = -0.291, CI = -0.342 - -0.240, p < 0.001). Flowsheet macros use and time in system also had a significant, negative relationship (AOR = -0.269, CI = -0.390 - -0.147, p = <0.001). Subgroups for department specialties showed time savings in flowsheet activities for medical surgical, critical care, and obstetrics units, however a significant relationship was not found in emergency and rehabilitation units. CONCLUSION/CONCLUSIONS:Utilization of flowsheet macros was associated with a decrease in the amount of time a nurse spends in both flowsheets and the EHR. Adoption and time savings varied by the department setting, suggesting flowsheet macros may not be applicable to all patient types or conditions. Future research should investigate if the time savings from this tool yield benefits in perceptions of nurse documentation burden.

Toddler visual attention development correlates with subsequent language, cognitive, and social developmental outcomes. This study investigates the association of maternal trauma on toddler looking behaviors in 39 mother-child dyads from the Western Cape Province, South Africa. At 15 months postpartum, maternal trauma was assessed using the Life Events Checklist and toddler multisensory attention skills were measured using the Multisensory Attention Assessment Protocol (MAAP) during eye-tracking. We used two-way mixed ANOVA to analyze the association of maternal trauma and MAAP condition with attention maintenance, intersensory matching, and attention shifting. This study provides support for the MAAP's reliability with a sample of 15-month-old toddlers from a low-income setting. We observed a significant interaction between MAAP condition and maternal trauma group on attention maintenance, but pairwise comparisons did not meet the threshold for statistical significance. In a stratified analysis, toddlers of mothers in the low trauma exposure group demonstrated significant differences in attention maintenance, intersensory matching, and attention shifting by condition. Unexpectedly, toddlers of mothers in the high trauma exposure group did not exhibit significant differences in these attentional skills, potentially indicating attentional adaptations. Further research is needed to explore the relationship between the intergenerational transmission of trauma on infant and toddler multisensory attention skills in low-income settings.

BACKGROUND AND PURPOSE/OBJECTIVE:Perfusion and perfusion-related parameter maps obtained using dynamic susceptibility contrast (DSC) MRI and dynamic contrast enhanced (DCE) MRI are both useful for clinical diagnosis and research. However, using both DSC and DCE MRI in the same scan session requires two doses of gadolinium contrast agent. The objective was to develop deep-learning based methods to synthesize DSC-derived parameter maps from DCE MRI data. MATERIALS AND METHODS/METHODS:Independent analysis of data collected in previous studies was performed. The database contained sixty-four participants, including patients with and without brain tumors. The reference parameter maps were measured from DSC MRI performed following DCE MRI. A conditional generative adversarial network (cGAN) was designed and trained to generate synthetic DSC-derived maps from DCE MRI data. The median parameter values and distributions between synthetic and real maps were compared using linear regression and Bland-Altman plots. RESULTS:Using cGAN, realistic DSC parameter maps could be synthesized from DCE MRI data. For controls without brain tumors, the synthesized parameters had distributions similar to the ground truth values. For patients with brain tumors, the synthesized parameters in the tumor region correlated linearly with the ground truth values. In addition, areas not visible due to susceptibility artifacts in real DSC maps could be visualized using DCE-derived DSC maps. CONCLUSIONS:DSC-derived parameter maps could be synthesized using DCE MRI data, including susceptibility-artifact-prone regions. This shows the potential to obtain both DSC and DCE parameter maps from DCE MRI using a single dose of contrast agent. ABBREVIATIONS/BACKGROUND:=plasma volume.

OBJECTIVE:To confirm feasibility and safety of the Da Vinci Single-Port (SP) System to perform pulmonary lobectomy procedures utilizing a subcostal, uniportal approach. METHODS:We performed a prospective, multicenter, single arm, clinical study evaluating performance and safety of the da Vinci SP Surgical System for pulmonary lobectomy. RESULTS:Nineteen subjects (benign, n=1; malignant, n=18) were enrolled at six academic medical centers in the United States and underwent robotic-assisted SP subcostal lobectomy. All SP lobectomy procedures were completed without conversion to multiport thoracoscopic/robotic or open approaches. No intraoperative adverse events or unanticipated adverse device effects were observed; 13 postoperative adverse events (AEs) commonly experienced after lobectomy were reported, 4 of which were Clavien-Dindo grade III. Rate of complete (R0) resection was 100%. The median (interquartile (IQR)) number nodal stations sampled was 6.5 (6.0-8.0) with a median of 17.5 (7.0-34.0) nodes resected per patient. CONCLUSIONS:Robotic SP subcostal lobectomy is feasible and is associated with acceptable perioperative and oncologic quality outcomes. Additional clinical experience and research is necessary to determine whether this alternative single incision approach has clinical benefit compared to standard transthoracic, multiport robotic lobectomy.

High-density microelectrode arrays have opened new possibilities for systems neuroscience, but brain motion relative to the array poses challenges for downstream analyses. We introduce DREDge (Decentralized Registration of Electrophysiology Data), a robust algorithm for the registration of noisy, nonstationary extracellular electrophysiology recordings. In addition to estimating motion from action potential data, DREDge enables automated, high-temporal-resolution motion tracking in local field potential data. In human intraoperative recordings, DREDge's local field potential-based tracking reliably recovered evoked potentials and single-unit spike sorting. In recordings of deep probe insertions in nonhuman primates, DREDge tracked motion across centimeters of tissue and several brain regions while mapping single-unit electrophysiological features. DREDge reliably improved motion correction in acute mouse recordings, especially in those made with a recent ultrahigh-density probe. Applying DREDge to recordings from chronic implantations in mice yielded stable motion tracking despite changes in neural activity between experimental sessions. These advances enable automated, scalable registration of electrophysiological data across species, probes and drift types, providing a foundation for downstream analyses of these rich datasets.

Racial/ethnic disparities in COVID-19 morbidity and mortality are serious in the United States, particularly among African American/Black and Latine (AABL) populations. Staying up-to-date on COVID-19 vaccination is essential for mitigating risk, but AABL vaccination rates are low. The present qualitative study explores perspectives on COVID-19 among AABL persons at high-risk for exposure to the SARS-CoV- 2 virus: frontline essential workers engaged in public-facing professions (e.g., retail). From a larger study of AABL frontline essential workers not up-to-date on COVID-19 vaccination, N = 50 participants were purposively sampled for maximum variability. Participants engaged in semi-structured qualitative interviews in English or Spanish that were audio-recorded, professionally transcribed, and translated into English as needed. Data were analyzed using a directed content analysis approach that was both inductive and theory-driven. Participants were 37 years old, on average, and most (65%) were men. Approximately half (56%) were Latine/Hispanic and 44% were African American/Black. Occupations included food preparation (40%), retail (28%), construction (12%), in-home health care (8%), and building maintenance and personal services (12%). Approximately a third (38%) had received ≥ 1 COVID-19 vaccine dose. We found COVID-19 vaccination perspectives were grounded in a larger context of medical and institutional distrust and past/ongoing systemic racism. In this context, results were organized into the following themes: general perspectives on COVID-19; barriers/facilitators related to race/ethnicity, social class, and community; specific aspects of the COVID-19 vaccine as barriers; mandates, incentives, and pressures to be vaccinated; and mixed effects of public health initiatives. Overall, participants were knowledgeable about COVID-19. Social norms reduced vaccine intentions but altruism and community/family concern could motivate it. Aspects of the public health response (e.g., advertisement campaigns targeting AABL populations) increased distrust and reduced vaccination willingness. However, at least some ambivalence about vaccination was common (participants would consider it). Yet there was a large gap between considering and receiving vaccination. Thus, barriers to COVID-19 vaccination for AABL frontline essential workers operate at multiple levels of influence, but are addressable. The present study yields recommendations to improve vaccination, including increasing the trustworthiness of systems and institutions, reducing systemic/structural barriers, harnessing social forces, and engaging AABL communities in program planning.
