Non-, a Treatable Provocateur of Parkinson's Disease: Hypothesis, Evidence and Species Specificity.

Epidemiological and eradication trial evidence indicates that , a major causative factor in peptic ulcer and gastric cancer, is a driver of the hypokinesia of Parkinson's disease (PD). Psychological (cognitive impairment, depression and anxiety) and gastrointestinal (peptic ulceration and constipation) PD features can precede the symptomatic onset of motor features by decades. We hypothesise that the non- (NHPH), which have farm, companion and wild animals as their main hosts, can have a role in PD aetiopathogenesis.

Factors affecting the non-publication of clinical trials of prevalent urological cancer.

Objectives: Clinical trials (CTs) are critical in understanding and managing cancer. However, despite being completed, CT results are often unpublished, compromising the ability to glean useful information from them. This study aimed to evaluate factors influencing the non-publication of urological oncology clinical trials.
