Project description:Background Tumor progression has been linked to stiffening of the extracellular matrix (ECM) caused by fibrosis. Cancer cells can be mechanically conditioned by stiff ECM, exhibiting a 1004-gene signature (MeCo score). Nintedanib has demonstrated anti-fibrotic activity in idiopathic pulmonary fibrosis. This study explores nintedanib’s anti-fibrotic effect on breast cancer outcomes. Methods We present long-term follow-up and analysis of a neoadjuvant randomized Phase 2 trial in early HER2-negative breast cancer. Patients (N = 130) underwent a baseline biopsy and received 12 paclitaxel courses alone (control arm) or in combination with nintedanib (experimental arm). Tumor MeCo score was determined by RNAseq. The primary aim was to assess nintedanib's impact on event-free survival (EFS) based on MeCo scores. Results Follow-up data were retrieved from 111 patients; 75 baseline and 24 post-run-in phase samples were sequenced. After median follow-up of 9.67 years, median EFS was not statistically different between arms (P = 0.37). However, in the control arm, High versus Low MeCo patients had a statistically higher relapse risk: hazard ratio (HR) = 0.21; P = 0.0075. This risk was corrected by nintedanib in the experimental arm: HR = 0.37; P = 0.16. Nintedanib demonstrated pharmacodynamic engagement, reducing the MeCo score by 25% during the run-in phase (P<0.01). Patients with Low MeCo after run-in had the best long-term prognosis (HR = 0.087; P = 0.03). Conclusions High MeCo is predictive of poor outcomes in HER2-negative early breast cancer, although this risk can be mitigated by nintedanib, which is able to specifically reduce mechanical conditioning.

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: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:BackgroundResearch on health-related quality of life (HRQL) has become increasingly important in recent decades. However, the impact of both living conditions and the level of autonomy impairments on HRQL in COPD patients receiving non-invasive ventilation (NIV) is still unclear.MethodsThe Severe Respiratory Insufficiency Questionnaire (SRI) was used to measure HRQL in a prospective cohort of COPD patients in whom home NIV was already established. Data on sociodemographics, clinical characteristics and standardized levels of autonomy impairment were evaluated. A multiple linear regression analysis was performed to identify the factors associated with a reduced HRQL.ResultsA total of 137 patients (67.0 ± 7.8 years, 45% female) were assessed. The mean SRI Summary Score was 54.1 ± 16.9 (95%CI: 51.1-57.1; N = 127). Regular ambulatory care was provided in 76% of patients, but only 37% underwent pulmonary rehabilitation. Overall, 69% of patients lived with family members, while 31% lived alone (family situation). Autonomy impairment levels were most serious in 3%, serious in 14%, and significant in 29% of patients, while 54% had no impairments at all. Of note, higher levels of autonomy impairment were markedly associated with lower SRI scores (regression coefficient - 6.5 ± 1.1 per level; P < 0.001). In contrast, family situation (0.2 ± 3.0; P = 0.959), ambulatory care by a respiratory specialist (1.7 ± 3.6; P = 0.638), and pulmonary rehabilitation (- 0.8 ± 3.1; P = 0.802) did not appear to influence HRQL. Possible subgroup effects were evident for the factors "impaired autonomy" and "living in a nursing home" (P = 0.016).ConclusionA higher level of autonomy impairment has been identified as the major determinant of reduced HRQL in COPD-patients receiving long-term NIV, particularly in those living in a nursing home.

Project description:BackgroundTungiasis (sand flea disease) is a neglected tropical skin disease caused by female sand fleas (Tunga spp.) embedded in the skin of the host. The disease is common in sub-Saharan Africa and predominantly affects children living in impoverished rural communities. In these settings tungiasis is associated with important morbidity. Whether tungiasis impairs life quality has never been studied.MethodsThe study was performed in 50 children with tungiasis, living in resource-poor communities in coastal Kenya. Based on the Dermatology Life Quality Index (DLQI) a tool was developed to determine life quality impairment associated with tungiasis in children, the tungiasis-related Dermatology of Life Quality Index (tungiasis-related-DLQI). Pain and itching were assessed using visual scales ranging from 0-3 points. The intensity of infection and the acute and chronic severity of tungiasis were determined using standard methods.ResultsSeventy eight percent of the patients reported a moderate to very large effect of tungiasis on life quality at the time of the diagnosis. The degree of impairment correlated with the number of viable sand fleas present in the skin (rho = 0.64, p < 0.001), the severity score of acute clinical pathology (rho = 0.74, p < 0.001), and the intensity of pain (rho = 0.82, p < 0.001). Disturbance of sleep and concentration difficulties were the most frequent restriction categories (86% and 84%, respectively). Four weeks after curative treatment, life quality had improved significantly. On the individual level the amelioration of life quality correlated closely with the regression of clinical pathology (rho = 0.61, p < 0.001).ConclusionThe parasitic skin disease tungiasis considerably impairs life quality in children in rural Kenya. After effective treatment, life quality improves rapidly.

Project description:BackgroundAlthough living kidney donation is safe, some donors experience perioperative complications.ObjectiveThis study explored how perioperative complications affected donor-reported health-related quality of life, depression, and anxiety.DesignThis research was a conducted as a prospective cohort study.SettingTwelve transplant centers across Canada.PatientsA total of 912 living kidney donors were included in this study.MeasurementsShort Form 36 health survey, Beck Depression Inventory and Beck Anxiety Inventory.MethodsLiving kidney donors were prospectively enrolled predonation between 2009 to 2014. Donor perioperative complications were graded using the Clavien-Dindo classification system. Mental and physical health-related quality of life was assessed with the 3 measurements; measurements were taken predonation and at 3- and 12-months postdonation.ResultsSeventy-four donors (8%) experienced a perioperative complication; most were minor (n = 67 [91%]), and all minor complications resolved before hospital discharge. The presence (versus absence) of a perioperative complication was associated with lower mental health-related quality of life and higher depression symptoms 3-month postdonation; neither of these differences persisted at 12-month. Perioperative complications were not associated with any changes in physical health-related quality of life or anxiety 3-month postdonation.LimitationsMinor complications may have been missed and information on complications postdischarge were not collected. No minimal clinically significant change has been defined for kidney donors across the 3 measurements.ConclusionsThese findings highlight a potential opportunity to better support the psychosocial needs of donors who experience perioperative complications in the months following donation.Trial registrationNCT00319579 and NCT00936078.
