Myotonic dystrophy type 1 (DM1) is the most common form of muscular dystrophy in adults, affecting multiple organs, including the eyes, heart, endocrine system, and central nervous system. The broad spectrum of DM1 symptoms has been attributed to the aberrant pre-mRNA splicing of various genes due to an abnormal expansion of the CTG repeat in the 3' untranslated region of the DMPK gene. The current challenge in the clinical care of DM1 is the lack of well-established protocols for the management of each organ disorder or symptom. Moreover, the current status of clinical management has not been adequately explored. Metabolic disturbance in DM1 has been less explored among the DM1 manifestations, even though impaired glucose tolerance is a widely known metabolic disorder associated with DM1. We investigated the metabolic disturbance related to DM1 using the national registry of neuromuscular diseases in Japan, Registry of Muscular Dystrophy (Remudy), and assessed the metabolic complications in DM1 and the current treatments. We obtained comprehensive information on the current status of liver dysfunction and dyslipidemia in a sizeable DM1 cohort (~300). We confirmed that the incidence of liver dysfunction and dyslipidemia, particularly hypertriglyceridemia, as well as impaired glucose tolerance, were significantly higher in DM1 patients. Furthermore, the majority of DM1 patients with dyslipidemia were not receiving pharmacotherapy. Our data highlight the current status of DM1 patients in Japan, which can guide the establishment of the standard of care for metabolic issues consequent to DM1.
To measure the rates of adverse obstetric outcomes in spontaneous delivery in a population of young women with high uptake of the bivalent human papillomavirus (HPV) vaccine.
This was a population-based ecological study with data from the Aberdeen Maternity and Neonatal Databank, UK. All women born between 1986-1996 with spontaneous singleton live birth at age 20-30 years were included for analysis. Exposure was defined according to maternal year of birth and HPV immunisation eligibility pre-immunisation cohort (1986-1990), catch-up immunisation cohort (1991-1994) and routine immunisation cohort (1995-1996). Outcomes were defined as spontaneous preterm birth (PTB), low birth weight (LBW) and pre-labour preterm rupture of membranes (pPROM). Generalized estimating equation models were applied, adjusted for deprivation, smoking status, marital status, body mass index, parity, maternal age and year of infant delivery.
A total of 6515 spontaneous singleton live births were included in final analysis, with 51ntaneous singleton live birth in either HPV immunised cohorts, although the additional benefit in improving obstetric outcomes cannot be excluded because of the limits of the sample size and the study design. Further demonstration is warranted when more women in the fully HPV immunised cohorts embark on pregnancy.Genomic disorders result from rearrangement of the human genome. Most genomic disorders are caused by copy number variants (CNV), deletions or duplications of several hundred kilobases. Many CNV loci are associated with autism, schizophrenia, and most commonly, intellectual disability (ID). However, there is little comparison of cognitive ability measures across these CNV disorders. This study aims to understand whether existing data can be leveraged for a cross-comparison of cognitive ability among multiple CNV. We found there is a lack of harmonization among assessment instruments and little standardization for reporting summary data across studies. HDAC assay Despite these limitations, we identified a differential impact of CNV loci on cognitive ability. Our data suggest that future cross-comparisons of CNV disorders will reveal meaningful differences across the phenotypic spectrum, especially if standardized phenotypic assessment is achieved.Malaria infection represents a major public health and economic issue that leads to morbidity and mortality globally. A highly effective and uncomplicated detection tool is required for malaria control in geographical hotspots of transmission. We developed a simple and more sensitive novel approach for the detection of the 18S rRNA gene of Plasmodium falciparum based on loop-mediated isothermal amplification (LAMP) and visualization using colorimetric, streptavidin-functionalized gold nanoparticles (SA-GNPs). Two loop primers of LAMP were biotinylated to produce biotin-containing products during amplification. After the addition of SA-GNPs, clusters of avidin-biotin complexes were established in the LAMP structure. While the positive reactions remained wine red, the negative reactions became colorless with partial aggregations induced by hydrochloric acid (HCl) under heat enhancement (60 °C). All steps of the assay were completed within 50 min, its detection limit was 1 parasite/μL, and it was highly specific for P. falciparum. This effortless detection system with high sensitivity and specificity could provide an alternative choice for malaria diagnostics in resource-limited regions.This study was designed to evaluate the effect of fresh pomegranate (Punica granatum L.) juice on the pharmacokinetic profile of artemether in healthy volunteers. A randomized, open-label, crossover study was conducted on healthy subjects (n = 26). Each volunteer received 250 mL of fresh pomegranate juice twice daily for 2 weeks. On day 14, they were administered a single oral dose of artemether (80 mg) with either water or 250 mL of pomegranate juice. Thirteen blood samples were collected up to 12 h and 6 electrocardiograms were recorded. Plasma concentrations of artemether and its metabolite dihydroartemisinin were analyzed by a noncompartmental method using LC-MS/MS. The lower limit of detection (LLOD) and lower limit of quantification (LLOQ) for artemether were estimated as 0.3 and 0.8 ng/mL, respectively, while for dihydroartemisinin it was 0.2 and 0.6 ng/mL, respectively. The pharmacokinetic parameters of artemether and dihydroartemisinin were not significantly altered when co-administered with the fresh pomegranate juice. AUC (0-∞) was slightly increased from 742 to 859 ng/mL for artemether [geometric mean ratio 1.14 (95 % CI, 1.08,1.18); P = 0.45] and from 699 to 818 ng/mL for dihydroartemisinin [geometric mean ratio 1.15 (95 % CI, 1.09, 1.15); P = 0.4]. Difference in Cmax for artemether was also statistically non-significant [173 vs 195 ng/mL; geometric mean ratio 1.09 (95 % CI, 0.91, 1.15); P = 0.61]. Likewise, elimination half-life (t1/2) for both artemether and dihydroartemisinin remained unchanged (P = 0.43 and 0.31, respectively). In addition, there was no significant difference in tmax for artemether (P = 0.66) and its metabolite (P = 0.65). In conclusion, findings of the present study demonstrated that the administration of pomegranate juice had no significant effect on the pharmacokinetic profile of artemether.
