Early ambulation protocol after diagnostic transfemoral cerebral angiography: an evidence-based practice project.

BACKGROUND: No uniform consensus has been achieved regarding the ambulation protocol after transfemoral cerebral angiography (TFA). Until now, in most hospitals patients are prescribed 8-12 h strict immobilization along with bed rest in the supine position after TFA in China, which causes great discomfort to patients. OBJECTIVE: To evaluate the effect of an evidence-based early ambulation protocol on the prevention of vascular complications and general discomfort in patients following transfemoral cerebral angiography (TFA). METHODS: A prospective quasi-experimental study was conducted on 214 patients undergoing TFA with manual compression. Patients in the experimental group were placed supine position for 2 h with a sandbag placed on the wound dressing, followed by a semi-seated position for another 2 h. After this period, patients took 2 h bed rest (move freely) with the sandbag removed, and were allowed to get out of bed 6 h after TFA. Patients in the control group were restricted to an 8 h bed rest in a supine position with the affected leg straight and immobilized. The vascular complications (bleeding, hematoma, ecchymosis) and levels of comfort (low back pain, leg pain, and blood pressure) were evaluated after the procedure. Numeric Rating Scale (NRS) pain scores, systolic blood pressure (SBP); diastolic blood pressure (DBP) were measured hourly for 8 h after TFA. RESULTS: There was no significant difference in the two groups with regard to vascular complications including bleeding events (P = 0.621), bleeding volume (P = 0.321), and area of hematoma (P = 0.156). The area of ecchymosis in the experimental group was significantly smaller than the control group (P = 0.031). Compared with the control group, the NRS score for low back pain in the 4th, 5th, 6th, 7th, and 8th hour after TFA were significantly lower (P < 0.05), and the NRS score for leg pain in the 5th, 6th, 7th, 8th hour after TFA were significantly lower (P < 0.05). The SBP and DBP in the 6th, 7th, and 8th hour after TFA were significantly lower than the control group (all P < 0.05). CONCLUSIONS: The evidence-based early ambulation protocol can effectively and safely increase comfort and decrease the pain level for patients undergoing TFA, without change in the incidence of vascular complications.

Efficacy of the ketogenic diet in Chinese children with Dravet syndrome: A focus on neuropsychological development.

OBJECTIVES: In this retrospective study, we evaluated the efficacy of the ketogenic diet (KD) treatment in Chinese children with Dravet syndrome (DS) as well as its effect on neuropsychological development. METHODS: Twenty-six children (14 male) living with DS and being treated with KD at our department between July 2014 and December 2017 were enrolled in the study. The efficacy of KD was measured by seizure frequency before and after the diet. Additionally, children's neuropsychological development, as evaluated by the Gesell developmental schedule, was compared between the KD and a non-KD group. RESULTS: After 3, 6, 12, 18, 24, and 30 months, 92.3%, 84.6%, 46.2%, 30.8%, 19.2%, and 19.2% remained on the KD, while 38.4%, 34.6%, 38.4%, 23.0%, 15.4%, and 15.4% showed >50% reduction in seizure. The development age (DA) subscores of 12 children, as measured by the Gesell developmental schedule, increased after commencement of KD. However, children's development quotient (DQ) subscores (age-adjusted) decreased after KD. In the non-KD group (40 participants), an increase of DA subscores and decrease of DQ subscores were also observed. Results found no difference in changes of DQ subscores over time between the two groups. The DQ subscores after the diet in the KD group (20 participants) did not differ significantly when compared to the DQ subscores at same age in the non-KD group (20 patients) (t-test). CONCLUSIONS: The DA subscores of 12 children in KD group increased after KD; when compared with that of the non-KD group, no significant difference was observed in respect to the changes of DQ subscore over time. Effects on cognitive and other neuropsychological development outcomes of KD for children living with DS require further study.

Next-generation sequencing improves treatment efficacy and reduces hospitalization in children with drug-resistant epilepsy.

BACKGROUND: The purposes of this study were three-fold: (i) to determine the contribution of known genes to the causation of a broad-spectrum of pediatric drug-resistant epilepsy (DRE), (ii) to compare the diagnostic yield and cost among different next-generation sequencing (NGS) approaches, and especially (iii) to assess how NGS approaches can benefit patients by improving diagnosis and treatment efficiency. METHODS: This study enrolled 273 pediatric DRE patients with no obvious acquired etiology. Seventy-four patients underwent whole-exome sequencing (WES), 141 patients had epilepsy-related gene panel testing, and another 58 patients had clinical WES gene panel testing. We obtained these patients' seizure and hospitalization frequency by periodic follow-up phone calls and outpatient visits. RESULTS: Genetic diagnosis was achieved in 86 patients (31.5%) and involved 93 likely disease-causing mutations in 33 genes. In this study, the detection rates of the epilepsy-related gene panel, the clinical WES gene panel, and WES were 32.6% (46/141), 44.8% (26/58), and 17.3% (13/74), respectively. Moreover, 34 patients accepted corrective therapy according to their mutant genes, after which 52.9% (18/34) became seizure-free and 38.2% (13/34) achieved seizure reduction. In the end, patients with either positive or negative genetic results had significantly fewer hospitalization incidents (times/half year) than before (positive genetic results group 0.58 ± 1.14 vs 0.10 ± 0.26; negative genetic results group 0.72 ± 1.65 vs 0.12 ± 0.33). CONCLUSIONS: These results offer further proof that NGS approaches represent powerful tools for establishing a definitive diagnosis. Moreover, this study indicated how NGS can improve treatment efficacy and reduce hospitalization in children with DRE.
