Supplementary Material for: Genetic Variants of the Copy Number Polymorphic β-Defensin Locus Are Associated with Sporadic Prostate Cancer
<p><i>Background/Aims:</i> Prostate cancer represents the cancer with
the highest worldwide prevalence in men. Chromosome 8p23 has shown
suggestive genetic linkage to early-onset familial prostate cancer and
is frequently deleted in cancer cells of the urogenital tract. Within
this locus some β-defensin genes (among them <i>DEFB4</i>, <i>DEFB103</i>, <i>DEFB104</i>)
are localized, which are arranged in a gene cluster shown to exhibit an
extensive copy number variation in the population. This structural
variation considerably hampers genetic studies. In a new approach
considering both sequence as well as copy number variations we aimed to
compare the defensin locus at 8p23 in prostate cancer patients and
controls. <i>Methods:</i> We apply PCR/cloning-based haplotyping and
high-throughput copy number determination methods which allow assessment
of both individual haplotypes and gene copy numbers not accessible to
conventional SNP-based genotyping. <i>Results:</i> We demonstrate association of four common <i>DEFB104 </i>haplotypes
with the risk of prostate cancer in two independent patient cohorts.
Moreover, we show that high copy numbers (>9) of the defensin gene
cluster are significantly underrepresented in both patient samples. <i>Conclusions:</i>
Our findings imply a role of the antibacterial defensins in prostate
cancerogenesis qualifying distinct gene variants and copy numbers as
potential tumor markers.</p
Supplementary Material for: Fatigue-related changes of daily function: most promising measures for the digital age
Background: Fatigue is a prominent symptom in many diseases, and is strongly associated with impaired daily function. The measurement of daily function is currently almost always done with questionnaires, which are subjective and imprecise. With the recent advances of digital wearable technologies, novel approaches to evaluate daily function quantitatively and objectively in real life conditions are increasingly possible. This also creates new possibilities to measure fatigue-related changes of daily function using such technologies.
Summary: This review examines in immune-mediated inflammatory and neurodegenerative diseases, which parameters may have the greatest potential to reflect fatigue-related changes of daily function.
Key Messages: Results of a standardized analysis of the literature reporting about perception-, capacity- and performance-evaluating assessment tools indicate that changes of the following parameters: physical activity, independence of daily living, social participation, working life, mental status, cognitive and aerobic capacity, and supervised and unsupervised mobility performance have the highest potential to reflect fatigue-related changes of daily function. These parameters thus hold the greatest potential for quantitatively measuring fatigue in representative diseases in real life conditions, e.g. with digital wearable technologies. Furthermore, to the best of our knowledge, this is a new approach to analysing evidence for the design of performance-based digital assessment protocols in human research, which may stimulate further systematic research in this area
