Abstract
INTRODUCTION AUA Guidelines do not support the routine use of ultrasound (US) in evaluation of boys with an undescended testicle (UDT) prior to urology referral. Multiple studies have demonstrated that real time US is inferior to a physical examination by a pediatric urologist in detecting an UDT. However, improved US technology, which now permits detection of the non-palpable testis located just proximal to the internal ring, may aid in guiding the surgical approach to the non-palpable testis. We evaluated US findings of boys deemed to have a non-palpable UDT and compared them to surgical findings. OBJECTIVE To assess the role of pre-operative ultrasonography in guiding surgical management in boys deemed to have a non-palpable testis by a pediatric urologist. STUDY DESIGN US of boys with a non-palpable UDT, as reported by a pediatric urologist on physical exam, during a 3-year period, were reviewed. All US were performed jointly by a technician and pediatric radiologist. Patient demographics, laterality, and intra-operative findings were assessed. RESULTS Thirty-one boys with a non-palpable testicle on physical exam underwent scrotal/inguinal/pelvis US at a median age of 7.5 months (IQR 2.5-12.3 months). Two patients had bilateral non-palpable testicles, 21 had a non-palpable left sided testicle and 8 had a non-palpable right sided testicle. Of the 33 non-palpable testes, 5 (15.2%) were identified in the inguinal canal. Sixteen (48.5%) were visualized in the lower pelvis just proximal to the internal ring and graded as intra-abdominal. Four (12.1%) nubbins or very atrophic testes were identified in the inguinal region or scrotum and 5 (15.2%) testes were not identified on US. Three (9.1%) testes were observed to be mobile between the lower pelvis just proximal to the internal ring and the inguinal canal. Of the 8 patients with testes that were identified in the inguinal canal, or mobile between the lower pelvis and inguinal canal, 7 avoided a diagnostic laparoscopy and underwent an inguinal orchiopexy. Of the 16 testicles located in the lower pelvis proximal to the internal ring, only 2 underwent laparoscopy/laparoscopic orchiopexy. DISCUSSION In cases of a non-palpable testicle following a physical examination by a urologist, an ultrasound can impact the operative plan, and allow for patients to avoid laparoscopy. In our cohort, 87.5% of non-palpable testes avoided laparoscopic surgery after ultrasound identification of a viable testis. CONCLUSIONS US in the evaluation of cryptorchidism can guide surgical management in select cases in which a testis is non-palpable following careful examination by a urologist.

Abstract
Background Increasing concerns regarding the safety of textured surface implants have resulted in surgeons transitioning from textured tissue expanders (TEs) to smooth TEs. Given this change has only recently occurred, this study evaluated outcomes between smooth and textured TEs. Methods Women who underwent two-stage breast reconstruction using TEs from 2013 to 2022 were included. TE-specific variables, perioperative information, pain scores, and complications were collected. Chi-squared, t -test, and linear regression analyses were performed. Results A total of 320 patients received a total of 384 textured and 152 smooth TEs. Note that 216 patients received bilateral reconstruction. TEs were removed in 9 cases. No significant differences existed between groups regarding comorbidities. Smooth TEs had a higher proportion of prepectoral placement ( p < 0.001). Smooth TEs had less fills (3 ± 1 vs. 4 ± 2, p < 0.001), shorter expansion periods (60 ± 44 vs. 90 ± 77 days, p < 0.001), smaller expander fill volumes (390 ± 168 vs. 478 ± 177 mL, p < 0.001), and shorter time to exchange (80 ± 43 vs. 104 ± 39 days, p < 0.001). Complication rates between textured and smooth TEs were comparable. Smooth TE had a greater proportion of TE replacements ( p = 0.030). On regression analysis, pain scores were more closely associated with age ( p = 0.018) and TE texture ( p = 0.046). Additional procedures at time of TE exchange ( p < 0.001) and textured TE ( p = 0.017) led to longer operative times. Conclusion As many surgeons have transitioned away from textured implants, our study shows that smooth TEs have similar outcomes to the textured alternatives.

Abstract
A number of cancer drugs activate innate immune pathways in tumor cells but unfortunately also compromise antitumor immune function. We discovered that inhibition of CARM1, an epigenetic enzyme and cotranscriptional activator, elicited beneficial antitumor activity in both cytotoxic T cells and tumor cells. In T cells, Carm1 inactivation substantially enhanced their antitumor function and preserved memory-like populations required for sustained antitumor immunity. In tumor cells, Carm1 inactivation induced a potent type 1 interferon response that sensitized resistant tumors to cytotoxic T cells. Substantially increased numbers of dendritic cells, CD8 T cells, and natural killer cells were present in Carm1-deficient tumors, and infiltrating CD8 T cells expressed low levels of exhaustion markers. Targeting of CARM1 with a small molecule elicited potent antitumor immunity and sensitized resistant tumors to checkpoint blockade. Targeting of this cotranscriptional regulator thus offers an opportunity to enhance immune function while simultaneously sensitizing resistant tumor cells to immune attack. SIGNIFICANCE: Resistance to cancer immunotherapy remains a major challenge. Targeting of CARM1 enables immunotherapy of resistant tumors by enhancing T-cell functionality and preserving memory-like T-cell populations within tumors. CARM1 inhibition also sensitizes resistant tumor cells to immune attack by inducing a tumor cell-intrinsic type 1 interferon response.This article is highlighted in the In This Issue feature, p. 1861.

Abstract
T cells are critical effectors of cancer immunotherapies, but little is known about their gene expression programs in diffuse gliomas. Here, we leverage single-cell RNA sequencing (RNA-seq) to chart the gene expression and clonal landscape of tumor-infiltrating T cells across 31 patients with isocitrate dehydrogenase (IDH) wild-type glioblastoma and IDH mutant glioma. We identify potential effectors of anti-tumor immunity in subsets of T cells that co-express cytotoxic programs and several natural killer (NK) cell genes. Analysis of clonally expanded tumor-infiltrating T cells further identifies the NK gene KLRB1 (encoding CD161) as a candidate inhibitory receptor. Accordingly, genetic inactivation of KLRB1 or antibody-mediated CD161 blockade enhances T cell-mediated killing of glioma cells in vitro and their anti-tumor function in vivo. KLRB1 and its associated transcriptional program are also expressed by substantial T cell populations in other human cancers. Our work provides an atlas of T cells in gliomas and highlights CD161 and other NK cell receptors as immunotherapy targets.

Abstract
Cytotoxic T cells play a key role in adaptive immunity by killing infected or cancerous cells. While the transcriptional control of CD8 T cell differentiation and effector function following T cell activation has been extensively studied, little is known about epigenetic regulation of these processes. Here we show that the histone deacetylase HDAC3 inhibits CD8 T cell cytotoxicity early during activation and is required for persistence of activated CD8 T cells following resolution of an acute infection. Mechanistically, HDAC3 inhibits gene programs associated with cytotoxicity and effector differentiation of CD8 T cells including genes encoding essential cytotoxicity proteins and key transcription factors. These data identify HDAC3 as an epigenetic regulator of the CD8 T cell cytotoxicity program.

Abstract
Psychiatric well-being impacts on general satisfaction and quality of life. This study explored how the presence of psychiatric diagnoses affects patient-reported outcomes in breast reconstruction and on selection of reconstructive modality. Patients who received breast reconstruction at a tertiary hospital between 2013 and 2018 and completed the BREAST-Q survey were included. BREAST-Q module scores were compared between patients who had a psychiatric diagnosis at presentation and the remaining cohort using t tests. General linear models (GLMs) were used to control for confounding factors. A chi-squared test was used to assess the effect on reconstructive modality, and binary logistic regression was used to control for confounding factors. Of the 471 patients included, 93 (19.7%) had at least one psychiatric diagnosis. Cohorts did not differ significantly by age, BMI, race, ASA classification, or insurance status. Patients with a psychiatric diagnosis experienced a decrease in BREAST-Q scores for the Psychosocial Wellbeing (B = 9.16, P = .001) and Sexual Wellbeing (B = 9.29, P = .025) modules. On binary logistic regression, patients with a psychiatric diagnosis were less likely to receive autologous reconstruction compared with implant reconstruction (OR = 0.489, P = .010). The presence of psychiatric diagnoses is an independent predictor of decreased BREAST-Q. Furthermore, there is a significant disparity in modality of reconstruction given to patients with psychiatric diagnoses. Further study is needed to evaluate interventions to improve satisfaction among at-risk populations and evaluate the reason for low autologous reconstruction in this population.
