Role of β3 subunit of the GABA type A receptor in triple negative breast cancer proliferation, migration, and cell cycle progression. Cell Cycle 2024:1-18. [PMID: 38623967 DOI: 10.1080/15384101.2024.2340912] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Accepted: 02/29/2024] [Indexed: 04/17/2024] Open
Abstract
Triple negative breast cancer (TNBC) is known for its heterogeneous nature and aggressive onset. The unresponsiveness to hormone therapies and immunotherapy and the toxicity of chemotherapeutics account for the limited treatment options for TNBC. Ion channels have emerged as possible therapeutic candidates for cancer therapy, but little is known about how ligand gated ion channels, specifically, GABA type A ligand-gated ion channel receptors (GABAAR), affect cancer pathogenesis. Our results show that the GABAA β3 subunit is expressed at higher levels in TNBC cell lines than non-tumorigenic cells, therefore contributing to the idea that limiting the GABAAR via knockdown of the GABAA β3 subunit is a potential strategy for decreasing the proliferation and migration of TNBC cells. We employed pharmacological and genetic approaches to investigate the role of the GABAA β3 subunit in TNBC proliferation, migration, and cell cycle progression. The results suggest that pharmacological antagonism or genetic knockdown of GABAA β3 subunit decreases TNBC proliferation and migration. In addition, GABAA β3 subunit knockdown causes cell cycle arrest in TNBC cell lines via decreased cyclin D1 and increased p21 expression. Our findings suggest that membrane bound GABAA receptors containing the β3 subunit can be further developed as a potential novel target for the treatment of TNBC.

Abstract
PURPOSE/OBJECTIVE(S) The Protocol-in-a-Day (PIAD) workshop was developed to support junior faculty and residents with clinical trial protocol design, with the main goal of providing initial feedback during development to reduce time for review and approval from institutional oversight committees. Our objectives are to mentor and educate participants and to evaluate the time to institutional approval by oversight committees. MATERIALS/METHODS PIAD provided concurrent educational feedback on 6 key elements of trial design. These included: (1) regulatory aspects; (2) institutional scientific review committee (SRC) and institutional review board (IRB); (3) clinical research and data coordination (including nursing); (4) statistics; (5) correlatives including imaging, biospecimens, and health services research/patient-reported outcomes; and (6) operations. The average number of days from submission to IRB approval or study activation for PIAD protocols was compared to other protocols submitted between January 2018 - January 2022 within the Division of Radiation Oncology. Participants were also given a 15-question survey to assess their perspective of the impact of the workshop. RESULTS A total of 25 protocols went through the PIAD workshop between January 2018-January 2022. Of the 25 protocols, 7 (28%) were excluded from this study due to not being submitted possibly after participants benefited from education on the limitations of their design. Eighteen protocols were included in our final analyses. These protocols included phase II (n = 11), phase 1 (n = 5), and phase III (n = 2). At the time of this report, all protocols (n = 18) have received IRB approval and have been activated. Protocol elements that could impact study activation included protocols requiring investigational new drug (IND) approval (n = 8) and multicenter studies (n = 1). Analyzing the time of submission to request for activation showed a decrease in time for protocols that went through PIAD vs those that did not [PIAD protocols, 254 days vs All other protocols, 262 days]. Likewise, those who attended PIAD had a lower average time from submission to IRB Approval [ PIAD protocols, 40 days vs All other protocols, 59 days]. All participants (100%) of the PIAD workshop responded that the educational program "improved the overall quality of the study design." The most commonly cited changes were protocol language (n = 17), statistics (n = 15), consent language (n = 8), and study design (n = 8). Aspects participants identified as the most educational included mentorship from regulatory, clinical research finance, and IRB review. CONCLUSION PIAD from participant surveys provided high educational value in the areas of improving trial quality, language and statistical design. When analyzing the average time, from 'submission to IRB initial approval' and 'submission to activation', PIAD protocols had a shorter time for approval, and thus suggests PIAD is effective in improving the overall design of protocols.

A combined exercise and cognitive training intervention induces fronto-cingulate cortical plasticity in first-episode psychosis patients. Schizophr Res 2023; 251:12-21.

Abstract
OBJECTIVE Schizophrenia (SZ) is characterized by neurobiological and associated cognitive and functional deficits, including pronounced cortical thinning, that lead to acute and long-term functional impairment. Research with older adults supports the role of non-pharmacological interventions, such as exercise (E) and cognitive training (CT), for cognitive impairments. This literature influenced the development of combined CT&E treatments for individuals with SZ. However, the impact of longer combined treatment duration (6 months) on neuroanatomy has yet to be explored in patients in the early course of the illness. The impact of adding exercise to cognitive training for key brain regions associated with higher-order cognition was examined here using magnetic resonance imaging (MRI) in first-episode psychosis (FEP) patients. METHODS UCLA Aftercare Research Program patients with a recent first episode of schizophrenia were randomly assigned to either combined cognitive and exercise training (CT&E) (N = 20) or cognitive training alone (CT) (N = 17) intervention. Cortical thickness was measured longitudinally and analyzed for two regions of interest using FreeSurfer. RESULTS Compared to patients in the CT group, those in the CT&E group demonstrated an increase in cortical thickness within the left anterior cingulate cortex over the six-month treatment period (ACC: F(1, 35) = 4.666, P < .04). Directional tendencies were similar in the left dorsolateral prefrontal cortex (DLPFC: F(1,35) = 4.132, P < .05). CONCLUSIONS These findings suggest that exercise and cognitive training may synergistically increase fronto-cingulate cortical thickness to mitigate progressive neural atrophy in the early course of SZ. This combined intervention appears to be a valuable adjunct to standard pharmacologic treatment in FEP patients.

Resectability of bilobar liver tumours after simultaneous portal and hepatic vein embolization versus portal vein embolization alone: meta-analysis. BJS Open 2022; 6:6844022. [PMID: 36437731 PMCID: PMC9702575 DOI: 10.1093/bjsopen/zrac141] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2022] [Revised: 09/09/2022] [Accepted: 10/05/2022] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND Many patients with bi-lobar liver tumours are not eligible for liver resection due to an insufficient future liver remnant (FLR). To reduce the risk of posthepatectomy liver failure and the primary cause of death, regenerative procedures intent to increase the FLR before surgery. The aim of this systematic review is to provide an overview of the available literature and outcomes on the effectiveness of simultaneous portal and hepatic vein embolization (PVE/HVE) versus portal vein embolization (PVE) alone. METHODS A systematic literature search was conducted in PubMed, Web of Science, and Embase up to September 2022. The primary outcome was resectability and the secondary outcome was the FLR volume increase. RESULTS Eight studies comparing PVE/HVE with PVE and six retrospective PVE/HVE case series were included. Pooled resectability within the comparative studies was 75 per cent in the PVE group (n = 252) versus 87 per cent in the PVE/HVE group (n = 166, OR 1.92 (95% c.i., 1.13-3.25)) favouring PVE/HVE (P = 0.015). After PVE, FLR hypertrophy between 12 per cent and 48 per cent (after a median of 21-30 days) was observed, whereas growth between 36 per cent and 67 per cent was reported after PVE/HVE (after a median of 17-31 days). In the comparative studies, 90-day primary cause of death was similar between groups (2.5 per cent after PVE versus 2.2 per cent after PVE/HVE), but a higher 90-day primary cause of death was reported in single-arm PVE/HVE cohort studies (6.9 per cent, 12 of 175 patients). CONCLUSION Based on moderate/weak evidence, PVE/HVE seems to increase resectability of bi-lobar liver tumours with a comparable safety profile. Additionally, PVE/HVE resulted in faster and more pronounced hypertrophy compared with PVE alone.

Abstract
Ameloblastoma (AB) is an odontogenic tumor that arises from ameloblast-lineage cells. Although relatively uncommon and rarely metastatic, AB tumors are locally invasive and destructive to the jawbone and surrounding structures. Standard-of-care surgical resection often leads to disfigurement, and many tumors will locally recur, necessitating increasingly challenging surgeries. Recent genomic studies of AB have uncovered oncogenic driver mutations, including in the mitogen-activated protein kinase (MAPK) and Hedgehog signaling pathways. Medical therapies targeting those drivers would be a highly desirable alternative or addition to surgery; however, a paucity of existing AB cell lines has stymied clinical translation. To bridge this gap, here we report the establishment of 6 new AB cell lines-generated by "conditional reprogramming"-and their genomic characterization that reveals driver mutations in FGFR2, KRAS, NRAS, BRAF, PIK3CA, and SMO. Furthermore, in proof-of-principle studies, we use the new cell lines to investigate AB oncogene dependency and drug sensitivity. Among our findings, AB cells with KRAS or NRAS mutation (MAPK pathway) are exquisitely sensitive to MEK inhibition, which propels ameloblast differentiation. AB cells with activating SMO-L412F mutation (Hedgehog pathway) are insensitive to vismodegib; however, a distinct small-molecule SMO inhibitor, BMS-833923, significantly reduces both downstream Hedgehog signaling and tumor cell viability. The novel cell line resource enables preclinical studies and promises to speed the translation of new molecularly targeted therapies for the management of ameloblastoma and related odontogenic neoplasms.

Abstract
STUDY PURPOSE The DRAGON 1 trial aims to assess training, implementation, safety and feasibility of combined portal- and hepatic-vein embolization (PVE/HVE) to accelerate future liver remnant (FLR) hypertrophy in patients with borderline resectable colorectal cancer liver metastases. METHODS The DRAGON 1 trial is a worldwide multicenter prospective single arm trial. The primary endpoint is a composite of the safety of PVE/HVE, 90-day mortality, and one year accrual monitoring of each participating center. Secondary endpoints include: feasibility of resection, the used PVE and HVE techniques, FLR-hypertrophy, liver function (subset of centers), overall survival, and disease-free survival. All complications after the PVE/HVE procedure are documented. Liver volumes will be measured at week 1 and if applicable at week 3 and 6 after PVE/HVE and follow-up visits will be held at 1, 3, 6, and 12 months after the resection. RESULTS Not applicable. CONCLUSION DRAGON 1 is a prospective trial to assess the safety and feasibility of PVE/HVE. Participating study centers will be trained, and procedures standardized using Work Instructions (WI) to prepare for the DRAGON 2 randomized controlled trial. Outcomes should reveal the accrual potential of centers, safety profile of combined PVE/HVE and the effect of FLR-hypertrophy induction by PVE/HVE in patients with CRLM and a small FLR.

Abstract
Objective: This study examined whether the use of party-safety strategies weakens the association between frequency of party attendance and sexual victimization among first-year female college students. Participants: First-year female college students (n = 450) from three universities in the United States participated in this study. Methods: Participants completed questionnaires on frequency of party attendance, use of party-safety strategies, and sexual victimization. Results: Frequency of party attendance was positively associated with sexual victimization. This association was moderated by use of party-safety strategies: frequency of party attendance was unrelated to sexual victimization when students reported greater use of party-safety strategies. However, frequency of party attendance was positively related to sexual victimization when students reported lower use of party-safety strategies. Conclusions: Teaching and reinforcing party-safety strategies may be helpful additions to efforts to prevent sexual victimization on college campuses.

Abstract
BACKGROUND This study investigated the impact of COVID-19 infection on hospitalized trauma patients. METHODS A retrospective review of hospitalized trauma patients at a level I trauma center was performed from March-December 2020. Data pertaining to patient demographics, presentation and hospital course was compared between COVID positive and negative trauma patients. RESULTS There were 4,912 patients and 179 (3.64%) were COVID-19 positive. Demographics and clinical presentation did not differ significantly between those with and without concomitant COVID-19. However, COVID positive trauma patients had higher rates of acute kidney injury (p = 0.016), sepsis (p = 0.016), unplanned intubation (p = 0.002) and unplanned return to the ICU (p = 0.01). The COVID positive cohort also had longer hospital stays (p < 0.01) with no significant difference in mortality. CONCLUSIONS In the setting of an ongoing pandemic, awareness of the complications COVID positive trauma patients are predisposed to is important for providers.

Abstract
Introduction La bronchiolite est une affection virale fréquente chez les enfants de moins de deux ans, atteignant les petites voies aériennes avec une inflammation aiguë des bronchioles, pouvant évoluer vers des difficultés respiratoires importantes. Le virus respiratoire syncitial (VRS) est responsable de plus de 70 % des infections. Le virus se transmet par la salive, les éternuements, la toux et les mains A Mayotte, la recrudescence saisonnière des cas de bronchiolite débute habituellement en janvier avec le plus souvent un pic épidémique en février et une épidémie qui se termine à la fin de l'été austral. Depuis la survenue de l'épidémie de Covid-19 dont les premiers cas ont été détectés à Mayotte en mars 2020, la saisonnalité des pathologies respiratoires a été fortement modifiée. Matériels et méthodes La surveillance épidémiologique de la bronchiolite à Mayotte repose sur deux sources de données. Le réseau de médecins sentinelles, instauré en 2009, rapporte la proportion de consultations pour bronchiolite parmi l'ensemble des consultations en ville et dans les centres de soins rattachés à l'hôpital. Le dispositif de surveillance des passages dans le service d'urgence de l'hôpital de Mayotte, mis en place depuis 2010, suit la proportion de passages pour bronchiolite parmi l'ensemble des passages. Toute l'année, les médecins hospitaliers assurent des prélèvements nasopharyngés et le laboratoire réalise un panel respiratoire permettant de détecter la présence des virus influenza, VRS, rhinovirus et entovirus et metapneumovirus Résultats En 2020 l'épidémie de bronchiolite est survenue selon la saisonnalité habituelle entre janvier et mars, avant la première vague de Covid de mai à juin 2020. La seconde vague de Covid-19 est survenue entre janvier et mars 2021 suivie de l'épidémie de bronchiolite qui est survenue avec trois mois de retard et une durée plus longue qu'habituellement de mai à septembre. La période inter-épidémique a été marquée par une circulation plus élevée du VRS chez les moins de deux ans par rapport aux niveaux de base habituellement observés. En 2021-2022 l'épidémie de bronchiolite a débuté dès le mois de décembre de manière précoce et s'est déroulée de manière concomitante avec la troisième vague épidémique de Covid-19 (fin décembre-janvier 2022). Fin février 2022, l'épidémie de bronchiolite 2022 est encore en cours. Conclusion Les mesures de prévention de la bronchiolite sont similaires à celles du Covid-19. Le retard de survenue de l'épidémie de 2021 laisse supposer une bonne adhésion de la population aux mesures de prévention lors des premières vagues de Covid-19 sur l'île. En revanche l'étendue de l'épidémie de bronchiolite de 2021 et la survenue de l'épidémie 2022 simultanément à la troisième vague de Covid-19 laissent supposer une lassitude de la population et une moindre application des mesures de protection nécessitant une adaptation de la stratégie de communication.

Abstract
This study provides insight on how sample recruitment methods may affect reported rates of sexual victimization on college campuses. The study compares sexual victimization rates among students who complete surveys after initial requests with those who complete them only after multiple reminders. Using probability sampling methods, undergraduate students from 12 universities were invited to complete a survey on campus violence; initial invitations were followed with up to five reminders. Women (n = 1,008) and men (n = 344) who completed surveys were categorized as early, middle, or late responders based on the number of reminders required to convert them from non-responders to responders. About 24.2% of women and 15.6% of men reported sexual victimization in the previous two months. In initial analyses, female early and late responders did not differ on sexual victimization, but males did. Male late responders reported higher rates of sexual victimization than early responders. In sensitivity analyses that re-defined early and late responders, women who were early responders reported more sexual victimization than women who were late responders, while men who were early responders reported less sexual victimization than men who were late responders. These findings suggest that researchers may underestimate sexual victimization rates for male college students unless multiple attempts are made to solicit their participation. Researchers are encouraged to utilize multiple reminders to increase research participation.

Vestibular testing in children - The suppression head impulse (SHIMP) test. Int J Pediatr Otorhinolaryngol 2021; 151:110921. [PMID: 34537549 DOI: 10.1016/j.ijporl.2021.110921] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2021] [Revised: 08/07/2021] [Accepted: 09/03/2021] [Indexed: 11/29/2022]
Abstract
INTRODUCTION The incidence of vestibular disorders and vertigo during childhood is increasing and pediatric clinicians have become more sensitive to children's balance disorders; thus, there is a need for appropriate detection test procedures for peripheral vestibular hypofunction. In order to ensure a reliable diagnosis and minimize misdiagnosis, a standardized clinical procedure via careful history and clinical examination is recommended. However, children, especially, are often unable to verbalize "vertigo" in a concrete manner, which often necessitates a consultation with a pediatrician holding nonspecific symptoms. The so-called suppression of the head impulse test (SHIMPs) represents a modification of the video head impulse test (HIMP) and is used for a more sensitive assessment of residual vestibular functions. In adults, SHIMPs are already an established diagnostic method. Nevertheless, to date, nothing is known about the applicability and standard values in childhood. MATERIAL AND METHODS In this monocentric, prospective study, we investigated whether SHIMPs enable a sensitive functional analysis of the vestibular system in healthy children of different ages. For this purpose, SHIMPs were performed in 40 children aged 3-18 years. RESULTS In this study, we demonstrated that SHIMPs can be easily performed in children (3-18 years). It is vital that the test be appropriately explained for children to ensure sufficient test tolerance and compliance. CONCLUSION SHIMPs are a helpful supplement to clinically established vestibular tests such as the HIMP in pediatric vestibular balance disorder diagnostics and can be integrated into the clinical routine, especially in children who have minimal verbal abilities or understanding of the instructions for HIMP. Similar to the HIMP, SHIMPs are characterized by a short test duration and a high tolerance.

Abstract
The broad diversity of microplastic litter requires a selection of analytical techniques to reliably determine the particle's chemical composition. This study demonstrates that Laser Induced Breakdown Spectroscopy (LIBS) can identify microplastic particles based on their spectral fingerprints. By studying the spectral features of polymer reference spectra, microplastic litter can be distinguished from non-plastic materials. The results show that LIBS can be used as a fast in-situ technique for pre-characterization of the microparticle's material and is a possible tool for environmental studies on microplastics.

Antidiuretic hormone inhibits osteogenic differentiation of dental follicle stem cells via V1a receptors and the PLC-IP 3 pathway. Arch Oral Biol 2021; 128:105169. [PMID: 34058720 DOI: 10.1016/j.archoralbio.2021.105169] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Revised: 05/16/2021] [Accepted: 05/25/2021] [Indexed: 11/18/2022]
Abstract
OBJECTIVE The aim of this study was to elucidate the molecular mechanism by which antidiuretic hormone (ADH) inhibited osteogenesis in dental follicle stem cells. DESIGN Rat dental follicle stem cells were cultured in osteogenic differentiation medium supplemented with ADH. Alkaline phosphatase enzyme activity, Alizarin Red S staining, MTT assay and RT-qPCR was used to examine ADH's impact on cell mineralization, viability, and osteogenic gene expression. Real-time calcium imaging analysis was performed to identify the ADH receptor and its mechanism of action. RESULTS ADH supplementation to the osteogenic differentiation medium inhibited cell mineralization without compromising cell viability and downregulated the expression of key osteogenic genes: DCN (Decorin), RUNX2 (Runt-related transcription factor 2) and BSP (Bone sialoprotein). Real-time calcium imaging analysis revealed that ADH (1-1000 nM) increased intracellular calcium in a concentration-dependent manner. Pretreatment of cells with V2255, a V1a receptor blocker, inhibited the calcium signals, but not with the V1b (Nelivaptan) or V2 (Tolvaptan). V2255 also reversed the inhibitory effect of ADH on osteogenesis. Furthermore, U73122, a Phospholipase C (PLC) inhibitor, 2-APB, an Inositol Triphosphate (IP3) receptor blocker, and depletion of endoplasmic reticulum calcium stores abolished the calcium signals by ADH. CONCLUSIONS Our results demonstrated that ADH activates V1a receptors and the PLC-IP3 pathway to stimulate intracellular calcium signals, which inhibits cell mineralization and osteogenic gene expression. These findings uncovered a novel function for ADH as a negative regulator of osteogenesis in dental follicle stem cells. The role of ADH in the pathogenesis of bone diseases remains to be determined.

Abstract
BACKGROUND Variation exists in the timing of tube feed initiation after percutaneous endoscopic gastrostomy (PEG) tube placement. The aim of our study was to review outcomes of early tube feed (ETF) versus late tube feed (LTF) initiation after PEG tube placement. METHODS We performed a retrospective review of all trauma patients who underwent PEG tube placement from 1/2014 to 12/2018. ETF was defined as initiation < 24 h and LTF > 24 h after placement. The primary outcome measure was feeding intolerance and secondary outcomes included post-operative complications. All statistical analyses were performed using standard statistical methods (e.g. Pearson's Chi-squared, Fisher's exact and Mann Whitney-U tests). RESULTS There were 295 patients (164 ETF and 131 LTF) that received a PEG tube at our level 1 trauma center. There was no difference with feeding intolerance at 12 h (5% vs. 4%; p = 0.88), 24 h (1% vs. 2%; p = 1.00), and 48 h (4% vs. 4%; p = 1.00). There was no difference when comparing intolerance symptoms such as nausea and vomiting (1% vs. 2%; p = 0.79), abdominal tenderness (2% vs. 3%; p = 0.76), high gastric residuals (2% vs. 2%; p = 1.00) and aspiration (0% vs. 2%; p = 0.39). There was no difference when comparing post-operative complications (4% vs. 8%; p = 0.21). CONCLUSIONS Early tube feeding after PEG placement is safe and equivalent to late tube feeding in the adult trauma population. Future prospective studies are warranted to establish the optimal timing for initiation of tube feeds after PEG tube placement.

Abstract
A clearer understanding of the tumor immune microenvironment (TIME) in metastatic clear cell renal cell carcinoma (ccRCC) may help to inform precision treatment strategies. We sought to identify clinically meaningful TIME signatures in ccRCC. We studied tumors from 39 patients with metastatic ccRCC using quantitative multiplexed immunofluorescence and relevant immune marker panels. Cell densities were analyzed in three regions of interest (ROIs): tumor core, tumor-stroma interface and stroma. Patients were stratified into low- and high-marker density groups using median values as thresholds. Log-rank and Cox regression analyses while controlling for clinical variables were used to compare survival outcomes to patterns of immune cell distributions. There were significant associations with increased macrophage (CD68+ CD163+ CD206+ ) density and poor outcomes across multiple ROIs in primary and metastatic tumors. In primary tumors, T-bet+ T helper type 1 (Th1) cell density was highest at the tumor-stromal interface (P = 0·0021), and increased co-expression of CD3 and T-bet was associated with improved overall survival (P = 0·015) and survival after immunotherapy (P = 0·014). In metastatic tumor samples, decreased forkhead box protein 3 (FoxP3)+ T regulatory cell density correlated with improved survival after immunotherapy (P = 0·016). Increased macrophage markers and decreased Th1 T cell markers within the TIME correlated with poor overall survival and treatment outcomes. Immune markers such as FoxP3 showed consistent levels across the TIME, whereas others, such as T-bet, demonstrated significant variance across the distinct ROIs. These findings suggest that TIME profiling outside the tumor core may identify clinically relevant associations for patients with metastatic ccRCC.

Abstract
Abstract
Introduction/Objective
Hirschsprung’s disease is a disorder associated with an absence of ganglion cells in a segment of the bowel. Total colonic and small bowel aganglionosis occurs in less than 1% of all Hirschsprung’s disease patients. Even rarer is the finding of Haddad syndrome, the coexistence of congenital central hypoventilation syndrome and Hirschsprung’s disease. Congenital central hypoventilation syndrome has approximately 1,000 reported cases, with colonic aganglionosis being associated with 15-20% of those cases. The prevalence of Hirschsprung’s disease with congenital renal anomalies may be another underreported finding.
Methods
Here, we report two rare cases of Hirschsprung’s disease with significant extension in the small bowel. One case involves a 38-week gestational age male infant admitted for apnea and another case involves 39-week gestational age female infant admitted for vomiting.
Results
Both infants had rectal suction biopsies confirming the absence of ganglion cells. The male infant had mapping biopsies which histologically showed hypertrophic nerve fibers and an absence of ganglion cells in the colon extending up to 70 cm proximal to the ileocecal valve. Calretinin immunostaining confirmed aganglionsis. Genetic testing showed a PHOX2B gene mutation carrying 32 polyalanine repeat mutations, confirming a diagnosis of congenital central hypoventilation syndrome coexisting with Hirschsprung’s disease. The female infant had intraoperative frozen sections that identified ganglion cells throughout the colon. On permanent sections, there was an absence of ganglion cells in the upper rectum extending up to 65 cm proximal to the ileocecal valve. She also was noted to have agenesis of the left kidney and a urachal remnant. Genetic testing was negative for RET mutations.
Conclusion
Overall, these cases provide further information on a rare variant of Hirschsprung’s disease that includes significant portions of the small bowel. Additionally, this study adds to the documented reports of Haddad syndrome and the connections between renal anomalies with Hirschsprung’s disease. Last, this series alludes to the difficulties of frozen section diagnosis of this disease.

Abstract
Abstract
Introduction
Tumor necrosis factor (TNF) has sleep regulatory roles. Neuronal action potentials enhance TNF expression. Neuron/glia co-cultures exhibit more intense local sleep-like states after TNF administration in vitro. Both TNF and TNF receptors (Rs) are produced as transmembrane (tm) proteins that can subsequently be cleaved to produce soluble (s) forms. With immunocytes, sTNFR can bind tmTNF and induce reverse signaling within the cell expressing the tmTNF. This is opposite of conventional signaling induced by soluble ligands (e.g. sTNF) binding to transmembrane receptors. Having previously shown sleep inhibition after sTNFR administration in vivo, we hypothesized that tmTNF-sTNFR binding would induce wake-like states in vitro through reverse signaling.
Methods
Somatosensory cortical neurons/glia, from wildtype (WT) mice and mice lacking either TNF (TNF-KO) or both TNFRs (TNFR-KO), were co-cultured on multi-electrode arrays. Daily one-hour recordings were taken consecutively on incubation days 4 - 13 for development analyses. On day 14, a one-hour baseline was recorded prior to treatment with sTNFR (0.0 ng/μL-120 ng/μL). Immediately after treatment, recordings resumed for one hour. Synchronization of electrical activity (SYN), action potentials, slow wave power (SWP; 0.25–3.75 Hz), and burstiness index (measures used to define sleep in vivo) were used to characterize the ontological emergence of these electrophysiological properties and sTNFR-induced changes in vitro.
Results
Development rates were reduced in TNF-KO cells and increased in TNFR-KO cells relative to each other and to WT mice. Additionally, after sTNFR treatments, cells from TNFR-KO mice, which still express TNF, exhibited dose-dependent decreased SYN and SWP, indicative of a wake-like state. In contrast, cells from TNF-KO mice lacked a response to sTNFR treatment.
Conclusion
To our knowledge, this is the first demonstration of reverse TNF signaling with respect to sleep/wake states. As such, it provides a new way of viewing state regulation and associated potential clinical applications.

Abstract
PURPOSE Healthcare facilities could minimize the cost of surgical instrument and implant processing by using single-use devices. The main objective was to prospectively compare the total cost of a single-use and reusable device used in short lumbar spine fusion. METHODS A 1-year, single-centre, prospective study was performed on patients requiring a one- or two-level lumbar arthrodesis. Patients were randomized in two groups treated with either reusable or single-use device. A cost minimization analysis was performed using a micro-costing approach from a hospital perspective. Every step of the preparation process was timed and costed based on hourly wages of hospital employees, cleaning supplies and hospital waste costs. RESULTS Forty cases were evaluated. No significant difference in operation time was noted (reusable 176.1 ± 68.4 min; single use 190.4 ± 71.7 min; p = 0.569). Mean processing time for single-use devices was lower than for reusable devices (33 min vs. 176 min) representing a cost of 14€ versus 58€ (p < 0.05). Pre-/post-sterilization and spinal set recomposing steps were the most time-consuming in reusable device group. A total cost saving of 181€ per intervention resulted from the use and processing of the single-use device considering an additional sterilization cost of 137€ with the reusable device. The weight of the reusable device was 42 kg for three containers and 1.2 kg for the single-use device. CONCLUSIONS Owing to the absence of re-sterilization, single-use devices in one- and two-level lumbar fusion allow significant money and time savings. They may also avoid delaying surgery in case of reusable device unavailability.

Abstract
With the growing burden of cancer in minority populations and limited progress in eliminating cancer disparities, it has become important to develop a diverse oncology workforce in basic, clinical, and behavioral research who will address cancer disparities and increase the participation of minority populations in clinical trials. To address the lack of well-trained underrepresented minority cancer scientists in Florida, the University of Florida collaborated with Florida A&M University in 2012 to establish the Florida Prostate Cancer Research Training Opportunities for Outstanding Leaders (ReTOOL) Program. Since 2012, the ReTOOL program has expanded to (1) cover all areas of cancer disparities; (2) offer training opportunities to minority students from all historically Black colleges and universities (HBCUs) in Florida; and (3) successfully secure both intramural and extramural federal funding to continuously provide research training opportunities for minority students in Florida. Focusing primarily on training Black students, the ReTOOL model includes culturally sensitive recruitment, mentorship, didactic curriculum, networking, and hands on experience in cancer research. This paper discusses the lessons learned from administering the ReTOOL program for 5 years, which includes having the right inputs (such as majority-minority institutions partnership, funding, faculty advisors, committed mentors, culturally competent staff, and standardized program requirements) and processes (such as pipeline approach, structured applications system, didactic curriculum, research experience, and continuous mentoring) for an effective research training program. The program impact is an increase in the pool of underrepresented minority candidates with scientific and academic career progression paths focused on reducing cancer health disparities.
