The prevalence of epilepsy was above 60% in every group with an abnormal MRI. CONCLUSION MRI results were conclusive in 86.4% of children with CP. It is highly encouraged to perform cranial MRI in every patient with CP. This article is protected by copyright.

The aim of this study was to describe provision of care coordination and explore the factors associated with quality of care coordination for Japanese CMC and their families. METHODS We used an exploratory cross-sectional study design. Participants were recruited at a children's hospital located in one prefecture, Japan. Primary caregivers raising children aged between less then 1 and 20 years and receiving reimbursements for children's home care medical fees were eligible to participants in this study. The study examined the relationship between parents' ratings of care coordination as "adequate," "inadequate," or "not received" and characteristics of children, parents, and families. RESULTS Ninety-nine parents caring for CMC were included in the analysis. Of those, 22.2% reported their child had a care coordinator. Caregivers were divided into three groups depending on the quality of care coordination Group 1 reported adequate care coordination; Group 2 reported inadequate care coordination; and Group 3 had no need for care coordination. We compared the socio-demographics of children, parents and families, their service use, and the HR-QOL and caregiver burden scores of parents across the three groups. The parents' free time, access to timely care for children, and service satisfaction were positively associated with adequate care coordination for CMC and their families. CONCLUSIONS Providing adequate care coordination for CMC and their families is essentials for access to timely services, and more positive psychological health of parents. High quality care coordination for CMC and their families is urgently needed in Japan. This article is protected by copyright.

The evaluation of metabolic stability of antisense oligonucleotides during biotransformation is critical due to concerns regarding drug safety. Since the effects of the modifications in ASOs on their metabolic stabilities are different from unmodified ASOs, studies that afford an understanding of these effects as well as propose proper methods to determine modified and unmodified ASO metabolites are imperative. An LC-MS/MS method offering good selectivity with a high-quality separation using 30 mM DMCHA and 100 mM HFIP was utilized to identify each oligonucleotide metabolite. Subsequently, the method was successfully applied to a variety of in vitro systems including endo/exonuclease digestion, mouse liver homogenates, and then liver microsomes, after which the metabolic stability of unmodified vs. modified ASOs were compared. Typical patterns of chain-shortened metabolites generated by mainly 3'-exonucleases were observed in phosphodiester and phosphorothioate ASOs, and endonuclease activity was identically observed in gapmers that showed relatively more resistance to nuclease degradation. Overall, the degradation of each ASO occurred more slowly corresponding to the degree of chemical modifications, while 5'-exonuclease activities were only observed in gapmers incubated in mouse liver homogenates. Our findings provide further understanding of the impact of modifications on the metabolic stability of ASOs, which facilitates the development of future ASO therapeutics.

AIM To provide data demonstrating the real-life burden of CU in the UK. METHODS This UK subset of the worldwide, prospective, non-interventional AWARE study included patients aged 18-75 years diagnosed with H1-antihistamine (H1-AH)-refractory chronic spontaneous urticaria (CSU) for >2 months. Baseline characteristics, disease activity, treatments, comorbidities and healthcare resource use were documented. Quality of life, work productivity and activity impairment were assessed. RESULTS Baseline analysis included 252 UK patients. Mean age and body mass index were 45.0 years and 29.0 kg/m2 , respectively. Most patients were female (77.8%) and had moderate/severe disease activity (mean Urticaria Activity Score over 7 days, 18.4) and a 'spontaneous' component to their CU (73.4% CSU; 24.6% CSU and chronic inducible urticaria). Common comorbidities included depression/anxiety (24.6%), asthma (23.8%) and allergic rhinitis (12.7%). A previous treatment was recorded for 57.9% of patients. Mean Dermatology Life Quality Index score was 9.5 and patients reported impairments in work productivity and activity. Healthcare resource use was high. Severity of CSU was associated with gender, obesity, anxiety and diagnosis. Only 28.5% of patients completed all nine study visits, limiting analysis of long-term treatment patterns and disease impact. CONCLUSIONS Adult H1-AH-refractory CU patients in the UK reported high rates of healthcare resource use and impairment in quality of life, work productivity and activity at baseline. The differing structures of UK healthcare may explain the high study discontinuation rates versus other countries. This article is protected by copyright.

XPP inhibits IgE production and prevents peanut-induced anaphylaxis. The XPP and emodin (IS) were determined in negative ion mode with m/z 239.0350→211.0400 and 269.0455→241.0507, respectively. The separation process was achieved by ACQUITY UPLC HSS T3 column (2.1 mm × 100 mm, 1.8 μm, Waters Corp., Milford, MA, USA) with acetonitrile and 0.1% formic acid in water (8515). The linear range was 0.5 ~ 100 ng/mL, and the correlation coefficient (r2 ) was greater than 0.993. The inter-day and intra-day precision was measured within an acceptable range of 15%. Pexidartinib research buy The extraction recovery and matrix effect were 78.9 to 87.2% and 94.3 to 98.5%, respectively. Under different conditions, the XPP was stable in the range of 5.6 ~ 10.6%. This method has been successfully applied to study the pharmacokinetics of XPP with oral dose of 10.0 mg/kg and intravenous dose of 2.
