Abstract
OBJECTIVE Racial inequities in sleep health are well documented and may be partially attributable to discrimination experiences. However, the effects of acute discrimination experiences on same-night sleep health are understudied. We quantified naturalistic discrimination experiences captured using ecological momentary assessment (EMA) and examined whether reporting discrimination on a given day predicted sleep health that night. METHOD Participants completed baseline assessments and a 17-day EMA protocol, with text prompts delivered four times daily to collect discrimination experiences. Seven different daily sleep characteristics were ascertained each morning. Discrimination reasons (e.g., because of my racial identity) were reported by participants and categorized into any, racial, or nonracial discrimination. Outcomes included the seven sleep diary characteristics. We fit generalized linear mixed effects models for each sleep outcome and discrimination category, controlling for key covariates. RESULTS The analytic sample included 116 self-identified Black and White individuals (48% Black, 71% assigned female at birth, average age = 24.5 years). Among Black participants, race-based discrimination was associated with a 0.5-hr reduction in total sleep time (TST). Among White individuals, nonracial discrimination was associated with a 0.6-hr reduction in TST, an earlier sleep offset, and reduced sleep efficiency (partly attributable to more nighttime awakenings). CONCLUSIONS Young adults may sleep worse on nights after experiencing discrimination, and different types of discrimination affect different sleep outcomes for Black and White individuals. Future studies may consider developing treatments that account for different sleep vulnerabilities for people experiencing discrimination on a given day.

Abstract
Vulvar cancer is annually diagnosed in an estimated 6,470 individuals and the vast majority are histologically squamous cell carcinomas. Vulvar cancer accounts for 5% to 8% of gynecologic malignancies. Known risk factors for vulvar cancer include increasing age, infection with human papillomavirus, cigarette smoking, inflammatory conditions affecting the vulva, and immunodeficiency. Most vulvar neoplasias are diagnosed at early stages. Rarer histologies exist and include melanoma, extramammary Paget's disease, Bartholin gland adenocarcinoma, verrucous carcinoma, basal cell carcinoma, and sarcoma. This manuscript discusses recommendations outlined in the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for treatments, surveillance, systemic therapy options, and gynecologic survivorship.

Abstract
BACKGROUND Berzosertib (M6620) is a highly potent (IC50 = 19 nM) and selective, first-in-class ataxia telangiectasia-mutated and Rad3-related protein kinase (ATR) inhibitor. This trial assessed the safety, preliminary efficacy, and tolerance of berzosertib in oesophageal cancer (A1 cohort) with RT and advanced solid tumours (A2 cohort) with cisplatin and capecitabine. METHODS Single-arm, open-label dose-escalation (Time-to-Event Continual Reassessment Method) trial with 16 patients in A1 and 18 in A2. A1 tested six dose levels of berzosertib with RT (35 Gy over 15 fractions in 3 weeks). RESULTS No dose-limiting toxicities (DLTs) in A1. Eight grade 3 treatment-related AEs occurred in five patients, with rash being the most common. The highest dose (240 mg/m2) was determined as the recommended phase II dose (RP2D) for A1. Seven DLTs in two patients in A2. The RP2D of berzosertib was 140 mg/m2 once weekly. The most common grade ≥3 treatment-related AEs were neutropenia and thrombocytopenia. No treatment-related deaths were reported. CONCLUSIONS Berzosertib combined with RT is feasible and well tolerated in oesophageal cancer patients at high palliative doses. Berzosertib with cisplatin and capecitabine was well tolerated in advanced cancer. Further investigation is warranted in a phase 2 setting.

Abstract
Depression pathology remains elusive. The monoamine hypothesis has placed much focus on serotonin, but due to the variable clinical efficacy of monoamine reuptake inhibitors, the community is looking for alternative therapies such as ketamine (neurogenesis theory of antidepressant action). There is evidence that different classes of antidepressants may affect serotonin levels; a notion we test here. We measure hippocampal serotonin in mice with voltammetry and study the effects of acute challenges of escitalopram, fluoxetine, reboxetine, and ketamine. We find that pseudo-equivalent doses of these drugs similarly raise ambient serotonin levels, despite their differing pharmacodynamics because of differences in Uptake 1 and 2, rapid SERT trafficking, and modulation of serotonin by histamine. These antidepressants have different pharmacodynamics but have strikingly similar effects on extracellular serotonin. Our findings suggest that serotonin is a common thread that links clinically effective antidepressants, synergizing different theories of depression (synaptic plasticity, neurogenesis, and the monoamine hypothesis).

Abstract
PURPOSE/OBJECTIVE(S) In some proton therapy facilities, patient alignment relies on two 2D orthogonal kV images, taken at fixed, oblique angles, as no 3D on-the-bed-imaging is available. The visibility of the tumor in kV images is limited since the patient's 3D anatomy is projected onto a 2D plane, especially when the tumor is behind a high-density structure such as bone. This can lead to a large patient setup error. A solution to this problem is to reconstruct the 3D CT image from the kV images obtained in the treatment position. MATERIALS/METHODS An asymmetric autoencoder-like network built with vision-transformer blocks was developed. The data was collected from a head and neck patient: 2 orthogonal kV images (1024X1024 voxels), 1 3D CT with padding (512X512X512) acquired from the in-room CT-on-rails before kVs were taken and 2 digitally-reconstructed-radiograph (DRR) images (512X512) based on the CT. We resampled kV images every 8 voxels and DRR and CT every 4 voxels, thus formed a dataset consisting of 262,144 samples, in which the images had a dimension of 128 for each direction. The value of each voxel in CT was normalized to range 0-1 with a uniform shift of 1000 and a denominator of 4000. For kV and DRR, we ranked all voxels value in an ascending order and normalized the values of the first 80% voxels to range 0-0.8 and the rest to range 0.8-1, thus yielding a quasi-Gaussian distribution, which was favorable by the deep neural networks. We further cropped kV and DRR images with a self-supervised bitmap based on the voxels' gradients. In training, both kV and DRR were utilized, and the encoder was encouraged to learn the same feature maps for kV images and its corresponding DRR images with mean-absolute-error (MAE) as the similarity loss. Then the decoder would reconstruct the 3D CT image from the feature maps of the kV images with the CT-on-rails as ground-truth (gCT) and MAE as the reconstruction loss. In testing, only independent kV images were used. The full-size synthetic CT (sCT) was achieved by concatenating the sCTs generated by the model according to their spatial information. The image quality of the sCT was evaluated using MAE and per-voxel-absolute-CT-number-difference volume histogram (CDVH). The proposed network was implemented with PyTorch deep learning library and both distributed data parallel (DDP) and automatic mixed precision (AMP) were applied to saving memory and accelerating the training speed. We used the AdamW optimizer with β1 = 0.9 and β2 = 0.999 and a cosine annealing learning rate scheduler with an initial learning of 1e-7 and 20 warm-up epochs. RESULTS The model achieved a MAE of <40HU and the CDVH showed that <5% of the voxels had a per-voxel-absolute-CT-number-difference larger than 185HU. The profile of a typical gCT slice and its corresponding sCT slice exhibited a high agreement, indicating the high similarity between the gCT and sCT. CONCLUSION A patient-specific vision-transformer-based network was developed and shown to be accurate and efficient to reconstruct 3D CT images from kV images.

Abstract
OBJECTIVES In May 2018, the Scottish Government introduced a minimum unit price (MUP) for alcohol of £0.50 (1 UK unit = 8 g ethanol) to reduce alcohol consumption, particularly among people drinking at harmful levels. This study aimed to evaluate MUP's impact on the prevalence of harmful drinking among adults in Scotland. STUDY DESIGN This was a controlled interrupted monthly time series analysis of repeat cross-sectional data collected via 1-week drinking diaries from adult drinkers in Scotland (N = 38,674) and Northern England (N = 71,687) between January 2009 and February 2020. METHODS The primary outcome was the proportion of drinkers consuming at harmful levels (>50 [men] or >35 [women] units in diary week). The secondary outcomes included the proportion of drinkers consuming at hazardous (≥14-50 [men] or ≥14-35 [women] units) and moderate (<14 units) levels and measures of beverage preferences and drinking patterns. Analyses also examined the prevalence of harmful drinking in key subgroups. RESULTS There was no significant change in the proportion of drinkers consuming at harmful levels (β = +0.6 percentage points; 95% confidence interval [CI] = -1.1, +2.3) or moderate levels (β = +1.4 percentage points; 95% confidence interval = -1.1, +3.8) after the introduction of MUP. The proportion consuming at hazardous levels fell significantly by 3.5 percentage points (95% CI = -5.4, -1.7). There were no significant changes in other secondary outcomes or in the subgroup analyses after correction for multiple testing. CONCLUSIONS Introducing MUP in Scotland was not associated with reductions in the proportion of drinkers consuming at harmful levels but did reduce the prevalence of hazardous drinking. This adds to previous evidence that MUP reduced overall alcohol consumption in Scotland and consumption among those drinking above moderate levels.

Abstract
Adenocarcinoma of the endometrium (also known as endometrial cancer, or more broadly as uterine cancer or carcinoma of the uterine corpus) is the most common malignancy of the female genital tract in the United States. It is estimated that 65,950 new uterine cancer cases will have occurred in 2022, with 12,550 deaths resulting from the disease. Endometrial carcinoma includes pure endometrioid cancer and carcinomas with high-risk endometrial histology (including uterine serous carcinoma, clear cell carcinoma, carcinosarcoma [also known as malignant mixed Müllerian tumor], and undifferentiated/dedifferentiated carcinoma). Stromal or mesenchymal sarcomas are uncommon subtypes accounting for approximately 3% of all uterine cancers. This selection from the NCCN Guidelines for Uterine Neoplasms focuses on the diagnosis, staging, and management of pure endometrioid carcinoma. The complete version of the NCCN Guidelines for Uterine Neoplasms is available online at NCCN.org.

Abstract
Black drinkers experience more alcohol problems compared to White drinkers at comparable levels of alcohol use (Mulia et al., 2009; Witbrodt et al., 2014; Zapolski et al., 2014). Research has found that Black compared to White drinkers endorse drinking to cope more frequently via retrospective report (Bradizza et al., 1999; Cooper et al., 2008). Additional research is needed to understand contributors to these racial differences. The primary aim of the present study was to examine how quality and frequency of cross-group contact at work and/or school relates to experiencing discrimination and, in turn, drinking to cope. Seventy-two young adult drinkers (Mage = 25, 72% female, 28% male; 64% Black, 36% White) completed baseline questionnaires and a subset (n = 50) completed a 17-day ecological momentary assessment (EMA) protocol. Cross-group contact frequency and quality was assessed at baseline while discrimination and coping motives were assessed via retrospective report at baseline and acutely via EMA. Accounting for sociodemographic covariates, path analyses utilizing retrospective measures revealed a significant indirect pathway from race to coping motives through quality of work/school cross-group contact and discrimination experiences related to assumptions of inferiority. Identical path analyses utilizing the acute EMA data revealed a significant indirect pathway from race to coping motives through quality of work/school cross-group contact. Improving cross-group contact at work and school may reduce drinking to cope. Additional research examining multiple domains of discrimination, quality of cross-group contact, and alcohol problems over time is needed to further understanding of social determinants of health inequities in alcohol problems.

Abstract
Background Prison-based hepatitis C treatment is safe and effective; however, many individuals are released untreated due to time or resource constraints. On community re-entry, individuals face a number of immediate competing priorities, and in this context, linkage to hepatitis C care is low. Interventions targeted at improving healthcare continuity after prison release have yielded positive outcomes for other health diagnoses; however, data regarding hepatitis C transitional care are limited. Methods We conducted a prospective randomized controlled trial comparing a hepatitis C care navigator intervention with standard of care for individuals released from prison with untreated hepatitis C infection. The primary outcome was prescription of hepatitis C direct-acting antivirals (DAA) within 6 months of release. Results Forty-six participants were randomized. The median age was 36 years and 59% were male. Ninety percent (n = 36 of 40) had injected drugs within 6 months before incarceration. Twenty-two were randomized to care navigation and 24 were randomized to standard of care. Individuals randomized to the intervention were more likely to commence hepatitis C DAAs within 6 months of release (73%, n = 16 of 22 vs 33% n = 8 of 24, P < .01), and the median time between re-entry and DAA prescription was significantly shorter (21 days [interquartile range {IQR}, 11–42] vs 82 days [IQR, 44–99], P = .049). Conclusions Care navigation increased hepatitis C treatment uptake among untreated individuals released from prison. Public policy should support similar models of care to promote treatment in this high-risk population. Such an approach will help achieve hepatitis C elimination as a public health threat.

Abstract
Depression is quickly becoming one of the world's most pressing public health crises, and there is an urgent need for better diagnostics and therapeutics. Behavioral models in animals and humans have not adequately addressed the diagnosis and treatment of depression, and biomarkers of mental illnesses remain ill-defined. It has been very difficult to identify biomarkers of depression because of in vivo measurement challenges. While our group has made important strides in developing in vivo tools to measure such biomarkers (e.g., serotonin) in mice using voltammetry, these tools cannot be easily applied for depression diagnosis and drug screening in humans due to the inaccessibility of the human brain. In this work, we take a chemical approach, ex vivo, to introduce a human-derived system to investigate brain serotonin. We utilize human induced pluripotent stem cells differentiated into serotonin neurons and establish a new ex vivo model of real-time serotonin neurotransmission measurements. We show that evoked serotonin release responds to stimulation intensity and tryptophan preloading, and that serotonin release and reuptake kinetics resemble those found in vivo in rodents. Finally, after selective serotonin reuptake inhibitor (SSRI) exposure, we find dose-dependent internalization of the serotonin reuptake transporters (a signature of the in vivo response to SSRI). Our new human-derived chemical model has great potential to provide an ex vivo chemical platform as a translational tool for in vivo neuropsychopharmacology.

Abstract
BACKGROUND AND AIMS Black drinkers compared with White drinkers experience more alcohol-related problems. Examination of social determinants of inequities in alcohol problems is needed. The current study measured (1) associations between acute stress and alcohol craving in the naturalistic environment for self-identified Black and White individuals who drink alcohol and (2) whether a history of attention deficit hyperactivity disorder (ADHD) moderated these associations. DESIGN AND SETTING Observational study using ecological momentary assessment (EMA) to collect data from participants at six semi-random time-points throughout the day during a 10-day period. A series of three-level multi-level models examined between- and within-person associations for stress and alcohol and tested if these associations differed for Black and White adults. PARTICIPANTS Participants were 229 adult drinkers (aged 21-35 years) who completed a larger study examining alcohol response for Black and White adults with and without a history of childhood ADHD. MEASUREMENTS Momentary stress and alcohol craving, ADHD history and socio-demographic characteristics (i.e. racial identity, sex, age, current education level, household income) were assessed. Participants were required to self-identify as either 'African American or Black' or 'European American or White'. FINDINGS Significant racial identity × stress interactions indicated that associations between stress and craving were stronger for Black compared with White adults across the 10-day period (between-person: B = 0.14, P = 0.007), concurrently within a given EMA time-point (within-person: B = 0.04, P = 0.001) and prospectively from time-point to time-point (within-person: B = 0.05, P = 0.001). Results remained while accounting for income × stress interactions. CONCLUSIONS Acute stress appears to be more strongly related to alcohol craving in self-identified Black compared with self-identified White individuals. This provides support for policy changes to eliminate structural inequities that increase stress exposure and the development of just-in-time culturally responsive interventions focused on coping with acute stress for Black individuals.

Abstract
Abstract
Background
False passage is a possible complication during operative hysteroscopy and can lead to termination of the intended procedure. The aim of this study is to describe two techniques to overcome the complication of false passage during operative hysteroscopy.
Results
This is a retrospective case series of 9 patients who had a false passage during operative hysteroscopy for Müllerian anomaly or endometrial polyps. The diagnosis was immediately made by visualization of a lattice network of myometrial fibers without normal landmarks of the endometrial cavity and tubal ostia. Once a false passage was suspected, an attempt was made to overcome this complication and complete the intended operative hysteroscopy. The hysteroscope was slowly withdrawn to identify both the false passage and the opening towards the internal cervical os. The hysteroscope was tilted towards the opening to the internal cervical os, and it was carefully advanced under direct vision into the endometrial cavity. In two patients, this technique failed because the opening to the internal cervical os was small, so the bridge of tissue between the internal os and false passage was partially divided using hysteroscopic scissors or a straight resectoscope loop, allowing for entry into the endometrial cavity. The intended procedures were completed successfully in all patients. No intraoperative or postoperative complications occurred as a result of the two techniques.
Conclusions
The techniques described in this study, to overcome false passage during operative hysteroscopy, appear to be safe, effective, and easy to perform. They enable the surgeon to complete the intended procedure.

Abstract
Carbon is the material of choice for electroanalysis of biological systems, being particularly applicable to neurotransmitter analysis as carbon fiber microelectrodes (CFMs). CFMs are most often applied to dopamine detection; however, the scope of CFM analysis has rapidly expanded over the last decade with our laboratory's focus being on improving serotonin detection at CFMs, which we achieved in the past via Nafion modification. We began this present work by seeking to optimize this modification to gain increased analytical sensitivity toward serotonin under the assumption that exposure of bare carbon to the in vivo environment rapidly deteriorates analytical performance. However, we were unable to experimentally verify this assumption and found that electrodes that had been exposed to the in vivo environment were more sensitive to evoked and ambient dopamine. We hypothesized that high in vivo concentrations of ambient extracellular glutamate could polymerize with a negative charge onto CFMs and facilitate response to dopamine. We verified this polymerization electrochemically and characterized the mechanisms of deposition with micro- and nano-imaging. Importantly, we identified that the application of 1.3 V as a positive upper waveform limit is a crucial factor for facilitating glutamate polymerization, thus improving analytical performance. Critically, information gained from these dopamine studies were extended to an in vivo environment where a 2-fold increase in sensitivity to evoked serotonin was achieved. Thus, we present here the novel finding that innate aspects of the in vivo environment are auspicious for detection of dopamine and serotonin at carbon fibers, offering a solution to our goal of an improved fast-scan cyclic voltammetry serotonin detection paradigm.

Abstract
BACKGROUND Dynamic optical coherence tomography (D-OCT) allows in vivo visualization of blood vessels in the skin and in malignant tumours. Vessel patterns in malignant melanoma may be associated with tumour stage. OBJECTIVE The aim of this study was to describe blood vessel patterns in melanomas and to correlate them with stage. METHODS One hundred fifty-nine malignant melanomas were assessed in a multicentre study. Every tumour was imaged using D-OCT prior to surgery and histologic evaluation. The tumour data such as thickness and ulceration as well as the staging at primary diagnosis and a follow-up of at least 40 months resulted in a stage classification. The vessel patterns were assessed according to predefined categories, compared with healthy adjacent skin, and correlated to stage. RESULTS Melanomas contained more blood vessels in different patterns compared with healthy adjacent skin. In particular, irregular vascular shapes such as blobs, coils, curves and serpiginous vessels were more common in melanomas. In addition, these patterns were significantly more often found in high-risk and metastatic melanomas than in low-risk lesions. CONCLUSION In melanomas, the density of the blood vessels is increased, and irregular vascular patterns are more frequent. At higher stages, especially in metastatic melanomas, these atypical vessels are significantly more common.

Abstract
BACKGROUND Indiana University possessed one of the earliest clinical proton facilities in the United States. The purpose of this study was to assess fatigue and nausea/vomiting in children with central nervous system (CNS) tumors undergoing radiation therapy as part of their treatment regimen, and to understand what factors influence fatigue. DESIGN: The study was approved by the institutional review board at Indiana University and consent and/or assent from eligible participants was obtained prior to enrollment. The validated Fatigue Scale is scored on a 5-point Likert scale. Surveys were completed 1) prior to radiation therapy, 2) week three of radiation therapy, and 3) week six of radiation therapy. A score of 41 or higher for the Fatigue Scale-Parent (< 7 years), 12 or higher for the Fatigue Scale-Child (8–12 years), and 17 or higher for the Fatigue Scale-Adolescent (13–18 years), indicates significant cancer-related fatigue. RESULTS The study aimed to recruit a total of 50 patients during the eligible period; however, data on 31 individual participants were available for analysis. 25 patients underwent proton radiation therapy, while 6 patients underwent conventional photon therapy. The mean age of children was 8.8 years. Of the 31 patients, 22 recorded scores indicating significant cancer-related fatigue at some point during radiation therapy. CONCLUSIONS Cancer related fatigue continues to be a challenge, with limited understanding of factors that might predict clinically relevant fatigue This work demonstrates the feasibility of conducting symptom research for children undergoing radiation therapy; further research is needed to characterize predictors of fatigue.

Impact of Lung Parenchymal-Only Failure on Overall Survival in Early-Stage Lung Cancer Patients Treated With Stereotactic Ablative Radiotherapy. Clin Lung Cancer 2020; 22:e342-e359.

Abstract
INTRODUCTION The impact of lung parenchymal-only failure on patient survival after stereotactic ablative body radiotherapy (SABR) for early-stage non-small-cell lung cancer (NSCLC) remains unclear. PATIENTS AND METHODS The study population included 481 patients with early-stage NSCLC who were treated with 3- to 5-fraction SABR between 2000 and 2016. The primary study objective was to assess the impact of out-of-field lung parenchymal-only failure (OLPF) on overall survival (OS). RESULTS At a median follow-up of 5.9 years, the median OS was 2.7 years for all patients. Patients with OLPF did not have a significantly different OS compared to patients without failure (P = .0952, median OS 4.1 years with failure vs. 2.6 years never failure). Analysis in a 1:1 propensity score-matched cohort for Karnofsky performance status, comorbidity score, and smoking status showed no differences in OS between patients without failure and those with OLPF (P = .8). In subgroup analyses exploring the impact of time of failure on OS, patients with OLPF 6 months or more after diagnosis did not have significantly different OS compared to those without failure, when accounting for immortal time bias (P = .3, median OS 4.3 years vs. 3.5 years never failure). Only 7 patients in our data set experienced failure within 6 months of treatment, of which only 4 were confirmed to be true failures; therefore, limited data are available in our cohort on the impact of OLPF for ≤ 6 months on OS. CONCLUSION OLPF after SABR for early-stage NSCLC does not appear to adversely affect OS, especially if occurring at least 6 months after SABR. More studies are needed to understand if OLPF within 6 months of SABR is associated with adverse OS. These data are useful when discussing prognosis of lung parenchymal failures after initial SABR.
