Project description:In this study, we identify leucyl-tRNA synthetase (LARS) as a breast tumor suppressor. To identify the mechanism underlying LARS-mediated breast tumor suppression, we first conducted charged tRNA profiling to assess charged and total tRNA-Leu expression in cell lines with high and low LARS expression. Expression of select charged and total tRNA-Leu isoacceptors were reduced in cell lines with lower LARS expression. We then conducted RNA-Seq and translation profiling including ribosome profiling (Ribo-Seq), polysome profiling in LARS-depleted cell lines. To test our hypothesis in vivo, we also performed RNA-Seq of ribosome-associated RNAs in Lars depleted PyMT tumors within RiboTag mice. The analyses implicate LARS as a regulator of leucine-rich translation.

Project description:Known clinical and genetic markers have limitations in predicting disease course and outcome in juvenile myelomonocytic leukemia (JMML). DNA methylation (DNAme) patterns in JMML have correlated with outcome across multiple studies, suggesting it as a biomarker to improve patient stratification. However, standardized approaches to classify JMML based on DNAme patterns are lacking. We therefore sought to define an international consensus for DNAme subgroups in JMML and develop classification methods for clinical implementation.

Project description:Evaluation of sensitivity and accuracy of widely used scoring functions Sequest, MaxQuant, Peaks, and Byonic. Spectra from E. coli were matched to human sequences, and human spectra from K052 cells were matched to A. loki sequences to determine specificity of matching and FDR estimation. A subsampling analysis of SCX-RP fractionation was performed.

Project description:In this study, we identify leucyl-tRNA synthetase (LARS) as a breast tumor suppressor. To identify the mechanism underlying LARS-mediated breast tumor suppression, we conducted TMT-proteomics in PyMT mouse tumors with monoallelic genetic deletion of LARS in the mammary tumor compartment. The analyses implicate LARS as a regulator of leucine-rich protein translation resulting in downregulation of candidate leucine-rich tumor suppressor genes.

Project description:Importance:The variation in both clinical appearance and responses to diverse treatment options emphasize the importance of an accurate, clinically relevant, yet easy-to-use scoring system in hidradenitis suppurativa. Objective:To propose and provide validation data for the newly designed Severity Assessment of Hidradenitis Suppurativa score. Design, Setting, and Participants:We prospectively assessed disease severity using Hurley staging and the modified Hidradenitis Suppurativa Score in 355 patients referred to Ruhr-University Bochum Department of Dermatology between March 2016 and June 2017. We also assessed disease severity via the Severity Assessment of Hidradenitis Suppurativa score. Main Outcomes and Measures:Evaluation and assessment of convergent validity and responsiveness to treatment of the Severity Assessment of Hidradenitis Suppurativa score. Results:Eighty-eight of the 355 patients (134 [37.7%] men and 221 [62.3%] women with a median [IQR] age of 40 [30-49] years) were classified as Hurley stage I, 221 were Hurley stage II, and 46 were Hurley stage III, with an overall median modified Hidradenitis Suppurativa Score of 31 (interquartile range [IQR], 19.3-53). The median total Severity Assessment of Hidradenitis Suppurativa score was 6 (IQR, 4-9), significantly different among the 3 Hurley groups. The median SAHS score for patients in Hurley stage I was 5 (IQR, 3-6), 6 (IQR, 5-9) for patients in Hurley stage II, and 9 (IQR, 7-12) for patients in Hurley stage III (P?<?.001, Kruskal-Wallis test). Correlation analysis showed a significant correlation between the modified Hidradenitis Suppurativa Score and the Severity Assessment of Hidradenitis Suppurativa score (r?=?0.79, P?<?.001). Disease severity assessment before and after 3 months of conservative systemic treatment showed a significant correlation between the Severity Assessment of Hidradenitis Suppurativa score and modified Hidradenitis Suppurativa Score. Both the mHSS (P?=?.001) and the SAHS score (P?<?.001) significantly differed between the baseline visit (median mHSS, 33 [IQR, 24-52]; median SAHS score, 6 [IQR, 5-9]) and the 3-month visit (median mHSS, 28 [IQR, 15-43.5]; median SAHS score, 5 [IQR, 4-6.3]). The 2 patient-reported items demonstrated excellent test-retest reliability with intraclass correlation coefficient values greater than 0.8. Conclusions and Relevance:Our validation data demonstrated that the Severity Assessment of Hidradenitis Suppurativa score is a disease severity instrument that significantly correlates with Hurley staging and the modified Hidradenitis Suppurativa Score, and is responsive enough to measure treatment outcome.

Project description:BackgroundLow anterior resection syndrome is pragmatically defined as disordered bowel function after rectal resection leading to a detriment in quality of life. This broad characterization does not allow for precise estimates of prevalence. The low anterior resection syndrome score was designed as a simple tool for clinical evaluation of low anterior resection syndrome. Although the low anterior resection syndrome score has good clinical utility, it may not capture all important aspects that patients may experience.ObjectiveThe aim of this collaboration was to develop an international consensus definition of low anterior resection syndrome that encompasses all aspects of the condition and is informed by all stakeholders.DesignThis international patient-provider initiative used an online Delphi survey, regional patient consultation meetings, and an international consensus meeting.ParticipantsThree expert groups participated: patients, surgeons, and other health professionals from 5 regions (Australasia, Denmark, Spain, Great Britain and Ireland, and North America) and in 3 languages (English, Spanish, and Danish).Main outcome measureThe primary outcome measured was the priorities for the definition of low anterior resection syndrome.ResultsThree hundred twenty-five participants (156 patients) registered. The response rates for successive rounds of the Delphi survey were 86%, 96%, and 99%. Eighteen priorities emerged from the Delphi survey. Patient consultation and consensus meetings refined these priorities to 8 symptoms and 8 consequences that capture essential aspects of the syndrome.LimitationsSampling bias may have been present, in particular, in the patient panel because social media was used extensively in recruitment. There was also dominance of the surgical panel at the final consensus meeting despite attempts to mitigate this.ConclusionsThis is the first definition of low anterior resection syndrome developed with direct input from a large international patient panel. The involvement of patients in all phases has ensured that the definition presented encompasses the vital aspects of the patient experience of low anterior resection syndrome. The novel separation of symptoms and consequences may enable greater sensitivity to detect changes in low anterior resection syndrome over time and with intervention.

Project description:To assess and improve the quality of oral healthcare, we must first agree on what constitutes good care. Currently there is no internationally accepted definition for quality of oral healthcare. Therefore, the purpose of the study was to establish a working definition for quality of oral healthcare that would help to advance further improvements in the field of quality improvement in oral healthcare. The development of the working definition included a 3-step approach: 1) literature screening; 2) expert-based compilation of an initial list of topics, leaning on the National Academy of Medicine framework for quality of care; and 3) a World Café with voting, which took place during the annual general meeting of the International Association for Dental Research in 2018. Following this approach, the collective intelligence of involved participants yielded a comprehensive list of items, prioritized by relevance. The resulting working definition comprises 7 domains—patient safety, effectiveness, efficiency, patient-centeredness, equitability, timeliness, access to care—and 30 items, which together characterize quality of oral healthcare. This aspirational working definition provides the potential to facilitate further conversations and activities aiming at quality improvement in oral healthcare. KNOWLEDGE TRANSFER STATEMENT:This special communication describes the development of a working definition for quality of oral healthcare. The findings of this study are intended to raise awareness of the relevance of quality improvement initiatives in oral healthcare. The working definition described here has the potential to facilitate further conversations and activities aiming at quality improvement in oral healthcare.
