ABSTRACT

Objective:To translate the Pressure Ulcer Quality of Life Questionnaire (PU-QOL) into Chinese and test its reliability and validity.Methods:The PU-QOL was translated, back translated, cross-cultural debugged and pre-investigated to form the Chinese version of PU-QOL. From August 2020 to November 2021, 405 patients with PU in wound clinics of two third-class hospitals in north and south regions of China were conveniently selected as the research objects.Results:The Chinese version of PU-QOL had 74 items. The content validity of the items was 0.80 to 1.00 and the content validity of the scale level was 0.95. Exploratory factor analysis extracted 7 common factors and the cumulative variance contribution rate was 60.79%. Each problem area is moderately correlated with the 12-Item Short Form Survey (SF-12), and the correlation coefficient between each dimension (0.13-0.28) was less than the correlation coefficient between each dimension and the total score of the scale and the difference was statistically significant( P<0.01). The Cronbach′s α coefficient was 0.84 and the retest reliability was 0.92. Conclusions:The Chinese version of PU-QOL questionnaire was proved to be a good instrument with acceptable reliability and validity, which can be used as a tool for evaluating quality of life of patients with PU in China.

ABSTRACT

The widespread application of next generation sequencing (NGS) in clinical settings has enabled testing, diagnosis, treatment and prevention of genetic diseases. However, many issues have arisen in the meanwhile. One of the most pressing issues is the lack of standards for reporting genetic test results across different service providers. The First Forum on Standards and Specifications for Clinical Genetic Testing was held to address the issue in Shenzhen, China, on October 28, 2017. Participants, including geneticists, clinicians, and representatives of genetic testing service providers, discussed problems of clinical genetic testing services across in China and shared opinions on principles, challenges, and standards for reporting clinical genetic test results. Here we summarize expert opinions presented at the seminar and report the consensus, which will serve as a basis for the development of standards and guidelines for reporting of clinical genetic testing results, in order to promote the standardization and regulation of genetic testing services in China.

ABSTRACT

BACKGROUND: Whole exome sequencing (WES) offers a powerful diagnostic tool to rapidly and efficiently sequence all coding genes in individuals presenting for consideration of phenotypically and genetically heterogeneous disorders such as suspected mitochondrial disease. Here, we report results of WES and functional validation in a consanguineous Indian kindred where two siblings presented with profound developmental delay, congenital hypotonia, refractory epilepsy, abnormal myelination, fluctuating basal ganglia changes, cerebral atrophy, and reduced N-acetylaspartate (NAA). METHODS: Whole blood DNA from one affected and one unaffected sibling was captured by Agilent SureSelect Human All Exon kit and sequenced on the Illumina HiSeq2000. Mutations were validated by Sanger sequencing in all family members. Protein from wild-type and mutant fibroblasts was isolated to assess mutation effects on protein expression and enzyme activity. RESULTS: A novel SLC25A12 homozygous missense mutation, c.1058G>A; p.Arg353Gln, segregated with disease in this kindred. SLC25A12 encodes the neuronal aspartate-glutamate carrier 1 (AGC1) protein, an essential component of the neuronal malate/aspartate shuttle that transfers NADH and H(+) reducing equivalents from the cytosol to mitochondria. AGC1 activity enables neuronal export of aspartate, the glial substrate necessary for proper neuronal myelination. Recombinant mutant p.Arg353Gln AGC1 activity was reduced to 15% of wild type. One prior reported SLC25A12 mutation caused complete loss of AGC1 activity in a child with epilepsy, hypotonia, hypomyelination, and reduced brain NAA. CONCLUSIONS: These data strongly suggest that SLC25A12 disease impairs neuronal AGC1 activity. SLC25A12 sequencing should be considered in children with infantile epilepsy, congenital hypotonia, global delay, abnormal myelination, and reduced brain NAA.
