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.

Effect of preoperative estrogen on complications after proximal hypospadias repair: A randomized controlled trial

Akash Bihari Pati, Pritinanada Mishra, Santosh K Mahalik et al. · 2023 · Indian Journal of Urology

Introduction: Proximal hypospadias repair has many postoperative complications such as urethrocutaneous fistulae, wound dehiscence, and urethral stricture. The beneficial effect of estrogen to promote wound healing has been known. We designed a study to determine whether preoperative stimulation of tissue with estrogen can reduce the postoperative complications associated with wound healing in patients undergoing hypospadias repair. Methods: Patients with proximal hypospadias requiring two-stage repairs (chordee correction followed by urethral tubularization) were randomized to estrogen and co

A Brief Intervention to Increase Uptake and Adherence of an Internet-Based Program for Depression and Anxiety (Enhancing Engagement With Psychosocial Interventions): Randomized Controlled Trial

Philip J Batterham, Alison L Calear, Matthew Sunderland et al. · 2021 · Journal of Medical Internet Research

BackgroundPsychosocial, self-guided, internet-based programs are effective in treating depression and anxiety. However, the community uptake of these programs is poor. Recent approaches to increasing engagement (defined as both uptake and adherence) in internet-based programs include brief engagement facilitation interventions (EFIs). However, these programs require evaluation to assess their efficacy. ObjectiveThe aims of this hybrid implementation effectiveness trial are to examine the effects of a brief internet-based EFI presented before an internet-based cognitive behavioral therapy self-

Veronika Keppner, Sebastian Krumpoch, Robert Kob et al. · 2023 · BMC Geriatrics

Abstract Background The risk of older adults being injured or killed in a bicycle accident increases significantly due to the age-related decline of physical function. Therefore, targeted interventions for older adults to improve safe cycling competence (CC) are urgently needed. Methods The “Safer Cycling in Older Age” (SiFAr) randomized controlled trial investigated if a progressive multi-component training program related to cycling improves CC of older adults. Between June 2020 and May 2022, 127 community-dwelling persons living in the area Nürnberg-Fürth-Erlangen, Germany aged 65 years and

Repetitive temporal interference stimulation improves jump performance but not the postural stability in young healthy males: a randomized controlled trial

Suwang Zheng, Tianli Fu, Jinlong Yan et al. · 2024 · Journal of NeuroEngineering and Rehabilitation

Abstract Background Temporal interference (TI) stimulation, an innovative non-invasive brain stimulation technique, has the potential to activate neurons in deep brain regions. The objective of this study was to evaluate the effects of repetitive TI stimulation targeting the lower limb motor control area (i.e., the M1 leg area) on lower limb motor function in healthy individuals, which could provide evidence for further translational application of non-invasive deep brain stimulation. Methods In this randomized, double-blinded, parallel-controlled trial, 46 healthy male adults were randomly di

Effects of simvastatin on white matter integrity in healthy middle‐aged adults

Nicholas M. Vogt, Jack F. V. Hunt, Yue Ma et al. · 2021 · Annals of Clinical and Translational Neurology

Abstract Background The brain is the most cholesterol‐rich organ and myelin contains 70% of total brain cholesterol. Statins are potent cholesterol‐lowing medications used by millions of adults for prevention of vascular disease, yet the effect of statins on cholesterol‐rich brain white matter (WM) is largely unknown. Methods We used longitudinal neuroimaging data acquired from 73 healthy, cognitively unimpaired, statin‐naïve, middle‐aged adults during an 18‐month randomized controlled trial of simvastatin 40 mg daily (n = 35) or matching placebo (n = 38).

Effect of High-Intensity Focused Ultrasound on sleep quality measures in obese doubled chin women: a randomized controlled trial

Nahla Tharwat Moussa Ahmed, Hany Ezzat Obaya, Azza Abd Elaziz Abd Elhadi et al. · 2025 · Вестник восстановительной медицины

INTRODUCTION. The double chin is an excessive accumulation of fat in the pre- and post-platysma that can manifest in various forms and sizes. Thin individuals might manifest a double chin, similar to those who are afflicted by obesity. It may result in a reduction in the definition of the mandible and give the perception of obesity or aging. AIM. To evaluate any effect of High-Intensity Focused Ultrasound (HIFU) on sleep quality measures in obese women with a double chin. MATERIALS AND METHODS. Typically, 60 women aged 35–50 years were selected from AL Qasr-Alaini Hospital and were equally div
