Self-Management Awareness in Patients on Maintenance Dialysis

The present study characterizes selfmanagement awareness in patients on maintenance dialysis. We conducted interviews with 9 patients on maintenance dialysis which were then analyzed by comparative content analysis. This was done in order to gather information to support future self-management. Seven categories emerged as a result of this analysis. Patients on maintenance dialysis were aware of a continuation and the need for dialysis treatment, perceived that they were handling self-management successfully, and were aware that they were proper managers able to carry out daily living. In addition, they sought support for their self-management through family and understanding people willing to assist them. Furthermore, these patients, now given the opportunity to reflect on their past selves, adopted the attitude, when I was not limited, and now that I am. Lastly, after comparing themselves to others, these patients perceived that each person's way of managing determined their future. We observed that patients on maintenance dialysis had unique self-management practices, and each was in search for their own “way of life, a way of being and dying in the future. The findings in this study suggest that in order for patients on maintenance dialysis to achieve selfmanagement and proper daily living, caregivers must provide support for the development of such self-management. This would allow relationships with other patients to develop, including relationships with family

Common Variants in CDKN2B-AS1 Associated with Optic-Nerve Vulnerability of Glaucoma Identified by Genome-Wide Association Studies in Japanese

BACKGROUND: To date, only a small portion of the genetic variation for primary open-angle glaucoma (POAG), the major type of glaucoma, has been elucidated. METHODS AND PRINCIPAL FINDINGS: We examined our two data sets of the genome-wide association studies (GWAS) derived from a total of 2,219 Japanese subjects. First, we performed a GWAS by analyzing 653,519 autosomal common single-nucleotide polymorphisms (SNPs) in 833 POAG patients and 686 controls. As a result, five variants that passed the Bonferroni correction were identified in CDKN2B-AS1 on chromosome 9p21.3, which was already reported to be a significant locus in the Caucasian population. Moreover, we combined the data set with our previous GWAS data set derived from 411 POAG patients and 289 controls by the Mantel-Haenszel test, and all of the combined variants showed stronger association with POAG (P<5.8 × 10(-10)). We then subdivided the case groups into two subtypes based on the value of intraocular pressure (IOP)--POAG with high IOP (high pressure glaucoma, HPG) and that with normal IOP (normal pressure glaucoma, NPG)--and performed the GWAS using the two data sets, as the prevalence of NPG in Japanese is much higher than in Caucasians. The results suggested that the variants from the same CDKN2B-AS1 locus were likely to be significant for NPG patients. CONCLUSIONS AND SIGNIFICANCE: In this study, we successfully identified POAG-associated variants in the CDKN2B-AS1 locus using a Japanese population, i.e., variants originally reported as being associated with the Caucasian population. Although we cannot rule out that the significance could be due to the differences in sample size between HPG and NPG, the variants could be associated specifically with the vulnerability of the optic nerve to IOP, which is useful for investigating the etiology of glaucoma

COSMIC (Cohort Studies of Memory in an International Consortium): An international consortium to identify risk and protective factors and biomarkers of cognitive ageing and dementia in diverse ethnic and sociocultural groups

BACKGROUND: A large number of longitudinal studies of population-based ageing cohorts are in progress internationally, but the insights from these studies into the risk and protective factors for cognitive ageing and conditions like mild cognitive impairment and dementia have been inconsistent. Some of the problems confounding this research can be reduced by harmonising and pooling data across studies. COSMIC (Cohort Studies of Memory in an International Consortium) aims to harmonise data from international cohort studies of cognitive ageing, in order to better understand the determinants of cognitive ageing and neurocognitive disorders. METHODS/DESIGN: Longitudinal studies of cognitive ageing and dementia with at least 500 individuals aged 60 years or over are eligible and invited to be members of COSMIC. There are currently 17 member studies, from regions that include Asia, Australia, Europe, and North America. A Research Steering Committee has been established, two meetings of study leaders held, and a website developed. The initial attempts at harmonising key variables like neuropsychological test scores are in progress. DISCUSSION: The challenges of international consortia like COSMIC include efficient communication among members, extended use of resources, and data harmonisation. Successful harmonisation will facilitate projects investigating rates of cognitive decline, risk and protective factors for mild cognitive impairment, and biomarkers of mild cognitive impairment and dementia. Extended implications of COSMIC could include standardised ways of collecting and reporting data, and a rich cognitive ageing database being made available to other researchers. COSMIC could potentially transform our understanding of the epidemiology of cognitive ageing, and have a world-wide impact on promoting successful ageing

Prevention of hypoglycemia by intermittent-scanning continuous glucose monitoring device combined with structured education in patients with type 1 diabetes mellitus : A randomized, crossover trial

Aims: We conducted a randomized, crossover trial to compare intermittent-scanning continuous glucose monitoring (isCGM) device with structured education (Intervention) to self-monitoring of blood glucose (SMBG) (Control) in the reduction of time below range. Methods: This crossover trial involved 104 adults with type 1 diabetes mellitus (T1DM) using multiple daily injections. Participants were randomly allocated to either sequence Intervention/Control or sequence Control/Intervention. During the Intervention period which lasted 84 days, participants used the first-generation FreeStyle Libre (Abbott Diabetes Care, Alameda, CA, USA) and received structured education on how to prevent hypoglycemia based on the trend arrow and by frequent sensor scanning (≥10 times a day). Confirmatory SMBG was conducted before dosing insulin. The Control period lasted 84 days. The primary endpoint was the decrease in the time below range (TBR; <70 mg/dL). Results: The time below range was significantly reduced in the Intervention arm compared to the Control arm (2.42 ± 1.68 h/day [10.1 %±7.0 %] vs 3.10 ± 2.28 h/day [12.9 %±9.5 %], P = 0.012). The ratio of high-risk participants with low blood glucose index >5 was significantly reduced (8.6 % vs 23.7 %, P < 0.001). Conclusions: The use of isCGM combined with structured education significantly reduced the time below range in patients with T1DM

Molecular phylogenetic relationships of halacarid mites suggest the reevaluation of traditional subfamily classification

International audienceMolecular phylogenetic relationships were examined for marine mites in the subfamilies Halacarinae, Copidognathinae, Rhombognathinae and Halixodinae from the aquatic mite family Halacaridae by using nuclear 18S and 28S ribosomal RNA gene sequences. The analysis revealed incongruences between the clustering obtained in the phylogenetic trees and the current morphological classification in the subfamilies Halacarinae and Rhombognathinae (based on 18S sequences) and in the Rhombognathinae (based on both 28S and combined 18S and 28S sequences). By contrast, the tree clustering was consistent with the morphological taxonomic positions in the Copidognathinae and Halixodinae subfamilies. It can be concluded that molecular phylogenetic analysis challenges the current classifications of Halacarinae and Rhombognathinae subfamilies. Accordingly diagnostic characters for their classification should be reevaluated
