Failure-mode index

Search what already failed

A searchable index of real negative results, null findings, and replication failures from the published literature — so you can learn what didn't work before repeating it.

WASTE indexes published research — it does not host or republish full papers. Each entry is a metadata record (title, authors, DOI) compiled from open scholarly databases, with the abstract shown in full only where the paper is openly licensed (e.g. Creative Commons); otherwise a short excerpt is shown for reference under fair use. WASTE classifies each work by failure type; classifications are automated and approximate.

Dyslexia and language impairment associated genetic markers influence cortical thickness and white matter in typically developing children

on behalf of the Pediatric Imaging Neurocognition Genetics study, John D. Eicher, Angela Montgomery et al. · 2015 · Brain Imaging and Behavior

Dyslexia and language impairment (LI) are complex traits with substantial genetic components. We recently completed an association scan of the DYX2 locus, where we observed associations of markers in DCDC2, KIAA0319, ACOT13, and FAM65B with reading-, language-, and IQ-related traits. Additionally, the effects of reading-associated DYX3 markers were recently characterized using structural neuroimaging techniques. Here, we assessed the neuroimaging implications of associated DYX2 and DYX3 markers, using cortical volume, cortical thickness, and fractional anisotropy. To accomplish this, we examin

Peak Width of Skeletonized Water Diffusion MRI in the Neonatal Brain

Manuel Blesa, Paola Galdi, Gemma Sullivan et al. · 2020 · Frontiers in Neurology

Preterm birth is closely associated with cognitive impairment and generalized dysconnectivity of neural networks inferred from water diffusion MRI (dMRI) metrics. Peak width of skeletonized mean diffusivity (PSMD) is a metric derived from histogram analysis of mean diffusivity across the white matter skeleton, and it is a useful biomarker of generalized dysconnectivity and cognition in adulthood. We calculated PSMD and five other histogram based metrics derived from diffusion tensor imaging (DTI) and neurite orientation and dispersion imaging (NODDI) in the newborn, and evaluated their accurac

Cerebrospinal Fluid Biomarkers in Spinocerebellar Ataxia: A Pilot Study

Ashley M. Brouillette, Gülin Öz, Christopher M. Gómez · 2015 · Disease Markers

Neurodegenerative diseases, including the spinocerebellar ataxias (SCA), would benefit from the identification of reliable biomarkers that could serve as disease subtype-specific and stage-specific indicators for the development and monitoring of treatments. We analyzed the cerebrospinal fluid (CSF) level of tau, α-synuclein, DJ-1, and glial fibrillary acidic protein (GFAP), proteins previously associated with neurodegenerative processes, in patients with the autosomal dominant SCA1, SCA2, and SCA6, and the sporadic disease multiple system atrophy, cerebellar type (MSA-C), compared with age-ma

Elevated de novo protein synthesis in FMRP-deficient human neurons and its correction by metformin treatment

Kagistia Hana Utami, Nur Amirah Binte Mohammad Yusof, Jing Eugene Kwa et al. · 2020 · Molecular Autism

FXS is the most common genetic cause of intellectual (ID) and autism spectrum disorders (ASD). FXS is caused by loss of FMRP, an RNA-binding protein involved in the translational regulation of a large number of neuronal mRNAs. Absence of FMRP has been shown to lead to elevated protein synthesis and is thought to be a major cause of the synaptic plasticity and behavioural deficits in FXS. The increase in protein synthesis results in part from abnormal activation of key protein translation pathways downstream of ERK1/2 and mTOR signalling. Pharmacological and genetic interventions that attenuate

Phenotyping of difficult asthma using longitudinal physiological and biomarker measurements reveals significant differences in stability between clusters

Tasneem Zaihra, Christopher J. Walsh, Sara Ahmed et al. · 2016 · BMC Pulmonary Medicine

BACKGROUND: Although the heterogeneous nature of asthma has prompted asthma phenotyping with physiological or biomarker data, these studies have been mostly cross-sectional. Longitudinal studies that assess the stability of phenotypes based on a combination of physiological, clinical and biomarker data are currently lacking. Our objective was to assess the longitudinal stability of clusters derived from repeated measures of airway and physiological data over a 1-year period in moderate and severe asthmatics. METHODS: A total of 125 subjects, 48 with moderate asthma (MA) and 77 with severe asth

Fluid balance control in critically ill patients: results from POINCARE-2 stepped wedge cluster-randomized trial

Pierre‐Édouard Bollaert, Alexandra Monnier, Francis Schneider et al. · 2023 · Critical Care

BACKGROUND: In critically ill patients, positive fluid balance is associated with excessive mortality. The POINCARE-2 trial aimed to assess the effectiveness of a fluid balance control strategy on mortality in critically ill patients. METHODS: POINCARE-2 was a stepped wedge cluster open-label randomized controlled trial. We recruited critically ill patients in twelve volunteering intensive care units from nine French hospitals. Eligible patients were ≥ 18 years old, under mechanical ventilation, admitted to one of the 12 recruiting units for > 48 and ≤ 72 h, and had an expected length of stay

Continuous neuromuscular blockade infusion for out-of-hospital cardiac arrest patients treated with targeted temperature management: A multicenter randomized controlled trial

Byung Kook Lee, In Soo Cho, Joo Suk Oh et al. · 2018 · PLoS ONE

INTRODUCTION: The aim of this trial was to investigate the effect of a continuous infusion of a neuromuscular blockade (NMB) in comatose out-of-hospital cardiac arrest (OHCA) subjects who underwent targeted temperature management (TTM). METHODS: In this open-label, multicenter trial, subjects resuscitated from OHCA were randomly assigned to receive either NMB (38 subjects) or placebo (43 subjects) for 24 hours. Sedatives and analgesics were given according to the protocol of each hospital during TTM. The primary outcome was serum lactate levels at 24 hours after drug infusion. The secondary ou

Towards implementation of cognitive bias modification in mental health care: State of the science, best practices, and ways forward

Janna N. Vrijsen, Ben Grafton, Ernst H. W. Koster et al. · 2024 · Behaviour Research and Therapy

Cognitive bias modification (CBM) has evolved from an experimental method testing cognitive mechanisms of psychopathology to a promising tool for accessible digital mental health care. While we are still discovering the conditions under which clinically relevant effects occur, the dire need for accessible, effective, and low-cost mental health tools underscores the need for implementation where such tools are available. Providing our expert opinion as Association for Cognitive Bias Modification members, we first discuss the readiness of different CBM approaches for clinical implementation, the

Recent human evolution has shaped geographical differences in susceptibility to disease

Urko M. Marigorta, Óscar Lao, Ferrán Casals et al. · 2011 · BMC Genomics

BACKGROUND: Searching for associations between genetic variants and complex diseases has been a very active area of research for over two decades. More than 51,000 potential associations have been studied and published, a figure that keeps increasing, especially with the recent explosion of array-based Genome-Wide Association Studies. Even if the number of true associations described so far is high, many of the putative risk variants detected so far have failed to be consistently replicated and are widely considered false positives. Here, we focus on the world-wide patterns of replicability of

A viroid-derived system to produce large amounts of recombinant RNA in Escherichia coli

Viruses have been engineered into useful biotechnological tools for gene therapy or to induce the synthesis of products of interest, such as therapeutic proteins and vaccines, in animal and fungal cells, bacteria or plants. Viroids are a particular class of infectious agents of higher plants that exclusively consist of a small non-protein-coding circular RNA molecule. In the same way as viruses have been transformed into useful biotechnological devices, can viroids be converted into beneficial tools?
