On the rank-distance median of 3 permutations.
Chindelevitch L, Pereira Zanetti JP, Meidanis J. Chindelevitch L, et al. BMC Bioinformatics. 2018 May 8;19(Suppl 6):142. doi: 10.1186/s12859-018-2131-4. BMC Bioinformatics. 2018. PMID: 29745865 Free PMC article.
In their paper, the authors provide an [Formula: see text] algorithm for determining three candidate medians, prove the tight approximation ratio [Formula: see text], and provide a sufficient condition for their candidates to be true medians. ...RESULTS: In this pap …

Median Approximations for Genomes Modeled as Matrices.
Zanetti JPP, Biller P, Meidanis J. Zanetti JPP, et al. Bull Math Biol. 2016 Apr;78(4):786-814. doi: 10.1007/s11538-016-0162-4. Epub 2016 Apr 12. Bull Math Biol. 2016. PMID: 27072561
In this paper, we model genomes as matrices and study the matrix median problem using the rank distance. It is known that, for any metric distance, at least one of the corners is a [Formula: see text]-approximation of the median. ...From the application point of vie …

Optimization of regional median equations of prenatal screening markers for trisomy 21 in a Chinese population.
Xu L, Huang H, Zheng L, He D, Lin N, Wang L, Lin Y. Xu L, et al. Medicine (Baltimore). 2018 Aug;97(35):e12045. doi: 10.1097/MD.0000000000012045. Medicine (Baltimore). 2018. PMID: 30170416 Free PMC article. Clinical Trial.
The applicability of the localized median equations was evaluated by the determination coefficient. Based on the established median equations, multiples of median (MoM) of each values were calculated and compared with the latest Down's syndrome quality assura …

Compromise or optimize? The breakpoint anti-median.
Larlee CA, Brandts A, Sankoff D. Larlee CA, et al. BMC Bioinformatics. 2016 Dec 15;17(Suppl 18):473. doi: 10.1186/s12859-016-1340-y. BMC Bioinformatics. 2016. PMID: 28105920 Free PMC article.
BACKGROUND: The median of k≥3 genomes was originally defined to find a compromise genome indicative of a common ancestor. However, in gene order comparisons, the usual definitions based on minimizing the sum of distances to the input genomes lead to degenerate medians

Efficacy of central nervous system prophylaxis with stand-alone intrathecal chemotherapy in diffuse large B-cell lymphoma patients treated with anthracycline-based chemotherapy in the rituximab era: a systematic review.
Eyre TA, Djebbari F, Kirkwood AA, Collins GP. Eyre TA, et al. Haematologica. 2020 Jul;105(7):1914-1924. doi: 10.3324/haematol.2019.229948. Epub 2019 Sep 5. Haematologica. 2020. PMID: 31488560 Free PMC article.
The median percentage receiving intrathecal prophylaxis was 11.9%. Cumulative CNS relapse incidence ranged from 1.9% at 6.5 years to 8.4% at 5 years. Median time (of medians) to CNS relapse was 10 months. 73% developed isolated CNS relapses, 24% concurrent CN …

Predicting Mean Survival Time from Reported Median Survival Time for Cancer Patients.
Lousdal ML, Kristiansen IS, Møller B, Støvring H. Lousdal ML, et al. Med Decis Making. 2017 May;37(4):391-402. doi: 10.1177/0272989X16655341. Epub 2016 Jul 10. Med Decis Making. 2017. PMID: 27353826
Mean survival time is rarely reported due to censoring imposed by limited follow-up time, whereas the median survival time often is. ...Based on theoretical considerations, we fitted a linear relationship between observed means and medians on the log scale. For vali …

Gut Microbiota Dysbiosis in Children with Relapsing Idiopathic Nephrotic Syndrome.
Tsuji S, Suruda C, Hashiyada M, Kimata T, Yamanouchi S, Kitao T, Kino J, Akane A, Kaneko K. Tsuji S, et al. Am J Nephrol. 2018;47(3):164-170. doi: 10.1159/000487557. Epub 2018 Mar 13. Am J Nephrol. 2018. PMID: 29533950
METHODS: Study subjects were 12 children with INS, 8 classified as relapsing (R group; median age: 3.0 years) and 4 as non-relapsing (NR group; median age: 4.3 years), and 11 healthy children (HC group; median age: 5.1 years) serving as normal controls. ...Fe …
