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.

INTRODUCTION[|]Seasonal and weather changes may affect the development of pulmonary embolism. The effects of seasonal and meteorological factors on mortality are controversial. We aimed to investigate the effects of seasons and meteorological data on patients with a low and high pulmonary embolism severity index and those with 30-day mortality. [¤]METHODS[|]Pulmonary embolism cases were included in our study. Daily pressure, humidity, temperature, and wind values were taken from the general online information by the Directorate of Meteorology. All cases were divided into the low-risk and high-

Aims and objectives: Vitamin D deficiency is a common finding and there is a suggested association with hypertension. Resistant hypertension is a clinical problem observed in 5–30% of hypertensive patients. Renal denervation (RDN) has been used for patients with resistant hypertension and has proven to lower blood pressure. Our primary goal was to assess the vitamin D serum concentration as a predictor of blood pressure response to RDN in highly selected patients. Methods: This prospective, nonrandomized, single-center study included 24 patients treated with RDN. Based on their one-year respon

Background: Acute post-thoracotomy pain (APTP) is severe and can lead to various respiratory complications if left untreated. Epidural (Ep) analgesia is the gold standard for APTP relief. Aims and Objectives: The aims and objectives of this study were to study the impact of low-dose oral pregabalin 75 mg on APTP. Materials and Methods: 100 patients were randomized into two groups (Group P and C). The Group P, study group received pregabalin 75 mg per oral preoperatively and for 2 days postoperatively. Group C received no medication. All the patients received thoracic Ep as a standard practice.

Introduction: Fas and FasL are known modulators of cellular apoptosis in immunoregulation of the innate immune response, as well as in the elimination of defective cells, and may be associated with antiviral activity of HTLV-1 – infected cells. Understanding the immunological mechanisms involved in the progression of HTLV-1 – associated diseases may contribute to predicting the clinical prognosis of infected individuals. Objective: To evaluate mRNA expression of the apoptotic modulators FAS and FASL in patients infected with HTLV-1. Methods: A total of 54 HTLV-1 – infected individuals were eva

This research analyses the impact of infill density and layer thickness on the tensile strength of test samples fabricated using FDM 3D printing, with a particular focus on comparing samples produced with and without an adhesion layer. A two-factor factorial experimental design was employed, consisting of two levels and three replications. The infill density (20% and 50%) and layer thickness (0.1 mm and 0.2 mm) were defined as input variables, while tensile strength served as the output variable. Statistical methods, such as ANOVA, were used to analyse the experimental data and evaluate the si

The clinical outcomes of different limus-based drug-eluting stents (DES) in a real-world setting have not been well defined. The aim of this study was to investigate the clinical outcomes of three different limus-based DES, namely sirolimus-eluting stent (SES), Endeavor zotarolimus-eluting stent (E-ZES) and everolimus-eluting stent (EES), using a national insurance claims database. We identified all patients who received implantation of single SES, E-ZES or EES between January 1, 2007 and December 31, 2009 from the National Health Insurance claims database, Taiwan. Follow-up was through Decemb

BACKGROUND: The cleansing of the colon for a colonoscopy exam must be complete so as to allow the visualization and inspection of the intestinal lumen. The ideal cleansing agent should be easily administered, have a low cost, and minimum collateral effects. Sodium picosulfate together with the magnesium citrate is a cathartic stimulant and mannitol is an osmotic laxative, both usually used for this purpose. AIMS: Assess the colon cleanliness comparing the use of mannitol and sodium picosulfate as well as evaluate the level of patient satisfaction, the presence of foam, pain, and abdominal dist

Abstract Background Malalignment of the ankle joint has been found after trauma, by neurological disorders, genetic predisposition and other unidentified factors, and results in asymmetrical joint loading. For a medial open wedge supramalleolar osteotomy(SMO), there are some debates as to whether concurrent fibular osteotomy should be performed. We assessed the changes in motion of ankle joint and plantar pressure after supramalleolar osteotomy without fibular osteotomy. Methods Ten lower leg specimens below the knee were prepared from fresh-frozen human cadavers. They were harvested from five
