Empirical evidence of study design biases in nutrition randomised controlled trials: a meta-epidemiological study

Julia Stadelmaier, Isabelle Roux, Maria Petropoulou & Lukas Schwingshackl
Abstract Background Instruments to critically appraise randomised controlled trials (RCTs) are based on evidence from meta-epidemiological studies. We aim to conduct a meta-epidemiological study on the average bias associated with reported methodological trial characteristics such as random sequence generation, allocation concealment, blinding, incomplete outcome data, selective reporting, and compliance of RCTs in nutrition research. Methods We searched the Cochrane Database of Systematic Reviews, for systematic reviews of RCTs, published between 01 January 2010 and 31...

Background:The impact of nonalcoholic fatty liver disease (NAFLD) on overall survival (OS), treatment response and toxicity in patients with hepatocellular carcinoma (HCC) treated with sorafenib is unknown. We examined the impact of NAFLD on survival and toxicity in an international cohort of patients receiving sorafenib.Methods:Clinical and demographic data were collected from patients consecutively treated at specialist centres in Europe and North America. The impact of NAFLD on OS, sorafenib-specific survival and toxicity compared with other...

Early clinical course of biopsy-proven IgA vasculitis nephritis

Abstract Background IgA vasculitis (IgAV) is the most common form of systemic vasculitis in childhood and frequently involves the kidney. A minority of patients with IgA vasculitis nephritis (IgAVN), especially those presenting with heavy proteinuria and/or kidney failure at onset, are at risk of chronic end-stage kidney disease. For deciding upon treatment intensity, knowledge of the short-term clinical course of IgAVN is needed to improve treatment algorithms. Methods For this retrospective multicenter study, the medical...

Temporal regulation of notch activation improves arteriovenous fistula maturation

Qunying Guo, Guang Chen, Hunter Cheng, Ying Qing, Luan Truong, Quan Ma, Yun Wang & Jizhong Cheng
Abstract Background Arteriovenous fistula (AVF) maturation is a process involving remodeling of venous arm of the AVFs. It is a challenge to balance adaptive AVF remodeling and neointima formation. In this study we temporally controlled Notch activation to promote AVF maturation while avoiding neointima formation. Methods Temporal Notch activation was controlled by regulating the expression of Notch transcription factor, RBP-Jκ, or dnMAML1 (dominant negative MAML2) in vascular smooth muscle cells (VSMCs). AVF mouse model was...

Association of sex steroid hormones and new bone formation rate after iliac onlay grafting: a prospective clinical pilot study

Victoria Constanze Landwehr, Tobias Fretwurst, Julia Heinen, Kirstin Vach, Katja Nelson, Susanne Nahles & Gerhard Iglhaut
Abstract Purpose The present prospective study evaluates the association between new bone formation rate in the iliac onlay graft and sex steroid hormone serum levels. Methods A total of 15 partially or completely edentulous postmenopausal females and 9 males with less than 5 mm height of the remaining alveolar bone underwent iliac onlay grafting followed by dental implant placement using a two-stage approach. Sex hormone binding globulin and 17β-estradiol serum levels were investigated by electrochemiluminescence...

Borrelia multiplex: a bead-based multiplex assay for the simultaneous detection of Borrelia specific IgG/IgM class antibodies

Abstract Background Lyme borreliosis (LB) is the most common tick-borne infectious disease in the northern hemisphere. The diagnosis of LB is usually made by clinical symptoms and subsequently supported by serology. In Europe, a two-step testing consisting of an enzyme-linked immunosorbent assay (ELISA) and an immunoblot is recommended. However, due to the low sensitivity of the currently available tests, antibody detection is sometimes inaccurate, especially in the early phase of infection, leading to underdiagnoses. Methods...

Prognostic value of tumor-infiltrating immune cells and immune checkpoints in elderly head-and-neck squamous cell carcinoma patients undergoing definitive (chemo)radiotherapy

Alexander Rühle, Jovan Todorovic, Simon S. K. Spohn, Eleni Gkika, Christoph Becker, Andreas Knopf, Constantinos Zamboglou, Tanja Sprave, Martin Werner, Anca-Ligia Grosu, Gian Kayser & Nils H. Nicolay
Abstract Background and purpose Tumor-infiltrating lymphocytes (TILs) are associated with locoregional control (LRC) in head-and-neck squamous cell carcinoma (HNSCC) patients undergoing (chemo)radiotherapy. As immunosenescence results in reduced immune activity, the role of TILs in elderly HNSCC patients may differ compared to younger patients, providing a rationale to study the prognostic role of TILs and immune checkpoints (ICs) in this population. Material and methods Sixty-three HNSCC patients aged ≥ 65 years undergoing definitive (chemo)radiotherapy between 2010...
