We report herein the use of nanofibrillated cellulose (NFC) for development of enzyme assemblies in an oriented manner for biotransformation with in situ cofactor regeneration. This is achieved by developing fusion protein enzymes with cellulose-specific binding domains. Specifically, lactate dehydrogenase and NADH oxidase were fused with a cellulose binding domain, which enabled both enzyme recovery and assembling in essentially one single step by using NFC. Results showed that the binding capacity of the enzymes was as high as 0.9 μmol-enzyme/g-NFC. https://www.selleckchem.com/products/uc2288.html Compared to native parent free enzymes, NFC-enzyme assemblies improved the catalytic efficiency of the coupled reaction system by over 100%. The lifetime of enzymes was also improved by as high as 27 folds. The work demonstrates promising potential of using biocompatible and environmentally benign bio-based nanomaterials for construction of efficient catalysts for intensified bioprocessing and biotransformation applications.PURPOSE To assess the neurocognitive function and neurological toxicity of frameless linear accelerator (LINAC)-based stereotactic radiosurgery (SRS) in patients with 10 or more brain metastases (BM). PATIENTS AND METHODS Forty consecutive adult patients who received SRS for ten or more 10 BM  less then  3 cm in maximum size were evaluated. All plans were generated using a single-isocenter multiple-target (SIMT) SRS technique with doses of 22 Gy for lesions  less then  2 cm and 16-18 Gy for those ≥ 2 cm in size. Survival analyses were estimated by Kaplan-Meier method from the date of SRS. Neurocognitive function using the Hopkins verbal learning test-revised (HVLT-R) and activity of daily living scale (ADLS) were collected prospectively at baseline and at 3,6 and 12-month follow-up. Toxicity was assessed by the National Cancer Institute Common Toxicity Criteria for Adverse Events (Version 5.0). RESULTS With a median follow-up of 10.8 months, 1-year survival and local control rates were 65% and 86%, respectively. Grade 2 or 3 toxicity occurred in eleven patients, being associated with radiological changes suggestive of radiation necrosis in seven patients. Three months after SRS, the mean relative decline was 14.2% for HVLT-R delayed recall, 12.3% for HVLT-R recognition, and 9.8% for HVLT-R total recall. A significant deterioration of HVLT-R scores ranged from 5.5 to 18.7% of patients at different time points. ADLS scores declined over time, but changes were not significant. CONCLUSIONS SRS is an effective and safe approach for patients with 10 or more BM able to maintain the pretreatment neurocognitive function in the majority of patients.BACKGROUND The diagnosis and treatment of canine scabies remain quite challenging as a result of the meddling of the invertebrate mite Sarcoptes scabiei var canis with the immunologic activity of its host. PURPOSE This study aims to evaluate and better understand the immunologic, histomorphometric, histopathologic changes as well as their relationship in scabies infestation. METHOD Ten healthy dogs were housed with five sarcoptes-ridden dogs. Skin biopsies were then obtained afterwards for 7 weeks into buffered formalin. Sections of obtained biopsies were processed and incubated in IL-4, IL-13, IL-17A and IL-23A antibodies, while the other sections were stained for cellular alterations, quantifications and measurement of tunnel height and diameters. Pearson's product-moment correlation was used to establish the association between the cytokines and the measured tunnel heights and diameters, while Student's t test and one-way analysis of variance were used to test for weekly significant differences in cytokine expressions. RESULTS Histopathologic changes and early expression of all studied cytokines, eosinophils and mast cells were pronounced from the second week of infestation. Quite notable was the consistent amount of IL-13 and IL-23A all through the study duration. A dissimilar association was also observed between anti-inflammatory cytokines (IL-4 and IL-13) and pro-inflammatory cytokines (IL-17A and IL-23A). Also observed was the negative relationship between IL-13 and IL-23A as an increase in IL-13 was associated with a decrease in IL-23A. Tunnel height increase was also positively associated with pro-inflammation. CONCLUSION Immunodiagnosis can possibly be achieved with IL-13 and IL-23A expressions, while immunotherapy seems possible with IL-13 cytokine therapy.Multiple sclerosis (MS) is a complex genetic trait characterized by demyelination of central nervous system (CNS), inflammation, and progressive neurological dysfunction. There is evidenced that autophagy and stress mechanisms are tightly linked with MS. Previous studies have demonstrated that LncRNAs TRPM2-AS and HNF1A-AS1 are involved in oxidative stress and autophagy, respectively. In the current study, we investigated the association of TRPM2-AS and HNF1A-AS1 single nucleotide polymorphisms (SNPs) with MS risk in 300 Iranian patients and 300 healthy controls. Our results have shown that T allele of the rs933151 was statistically significant underrepresented in MS patients compared with healthy subjects (OR (95% CI) = 0.696 (0.532-0.911), P = 0.005). This SNP was associated with lower MS risk in codominant and dominant models (OR (95% CI) = 0.68 (0.48-0.96), P value = 0.032; OR (95% CI) = 0.65 (0.47-0.91), P value = 0.012, respectively). The rs7953249 was not associated with MS susceptibility in any inheritance models (P values of 0.73, 0.46, 0.61, and 0.71 for codominant, dominant, recessive, and overdominant models, respectively). Present study highlighted a novel association at the TRPM2-AS gene (SNP rs933151) with MS susceptibility.PURPOSE Elevated body temperature might change glucose metabolism in human organs. The purpose of this study is to explore 18F-FDG distribution in febrile patients on the day of 18F-FDG PET/CT scanning and compare it with patients with a normal temperature. PROCEDURES 18F-FDG PET/CT was performed on 69 febrile patients and 82 patients with a normal temperature. Patient sociodemographic data, blood glucose levels before PET/CT, body temperature on the day of the exam, and laboratory test results were collected. Maximal standard uptake values (SUVmax) in the brain, mediastinal blood pool, liver, spleen, and the bone marrow were compared. RESULTS Compared with the controls, SUVmax of the febrile patients was significantly lower in the brain, mediastinal blood pool, and the liver (p  0.05). Body temperature was found negatively correlated with SUVmax in the brain (r = - 0.646), mediastinal blood pool (r = - 0.530), and the liver (r = - 0.384), and positively correlated with the SUVmax in the spleen (r = 0.592) and bone marrow (r = 0.

OBJECTIVE Status epilepticus is associated with high rates of morbidity and mortality; thus, early diagnosis and proper treatment are crucial. We aimed to study the etiology, clinical features, and treatment among pediatric patients with convulsive status epilepticus. METHODS The medical records of 100 patients were retrospectively obtained from pediatric intensive care unit. Etiology, clinical features, and treatment were interpreted by using Fisher exact test, χ test, and Spearman ρ correlation coefficient. RESULTS Seizures had stopped with the first-, second-, and third-line treatment in 29%, 36%, and 35% of the patients, respectively. Only phenytoin treatment was efficient; it has 32.3% rate in second-line treatment. Whereas mortality rate was 10%, morbidity rate was 14% during the follow-up. Epilepsy, hemiparesis, spastic tetraparesis, and mental retardation developed. Mortality was significantly much more in the patients with refractory seizure and cerebral palsy. Development of mental retardation was much higher in the male sex. CONCLUSIONS Phenytoin is still one of the most efficient antiepileptic drugs. If the duration of status epilepticus can be shortened by prompt treatment, neurological complications may be prevented.OBJECTIVE Intimate partner violence (IPV) is a serious public health concern and impacts the entire family unit, particularly children. We implemented an IPV screening and referral program in an urban pediatric emergency department (ED) and aimed to screen 30% of patient families for IPV by January 1, 2017. METHODS We used a quality improvement initiative using a nonverbal screening card to screen families when the caregiver was the sole adult present and spoke English and/or Spanish, and the patient was medically stable. Interventions included education, culture of screening initiatives, feedback, and process changes to emergency medical record (EMR) documentation. The primary outcome measure was percentage of caregivers screened in the ED over time. Our balancing measure was ED length of stay. RESULTS After process improvement implementations that include requiring IPV screen documentation in the EMR, using Research Electronic Data Capture for referrals, and standardizing and simplifying the screening process, caregiver screening rates increased to 30% and have remained consistently at or above that rate during the 15-month postevaluation phase. This intervention did not impact length of stay in the ED. CONCLUSIONS An innovative multiphase quality improvement approach to screen for IPV using a nonverbal screening card and technology within the EMR was successfully implemented in our pediatric ED. Both IPV screening and documentation rates demonstrated greatest improvement and sustainability after process improvements over other initiatives.OBJECTIVES This study aimed to determine if the 2016 clinical practice guidelines regarding brief resolved unexplained events (BRUE) impacted our institutional approach to infants with BRUE. We sought to determine the statement's impact on admission rates, emergency department (ED) length of stay, and return ED visits or readmissions. METHODS We conducted a retrospective chart review of patients who presented to the ED at a tertiary pediatric hospital from January 2014 to June 2019. Diagnostic workup (laboratory testing, imaging, monitoring) in the ED was recorded. Cohorts of patients presenting pre- and post-2016 guideline were compared using χ and t tests. Subanalysis of higher-risk and lower-risk infant groups was also performed. RESULTS The demographics of the 2 cohorts were not significantly different. Comparison showed significant reductions in invasive testing after the guideline, both overall (P = 0.005), and specifically regarding comprehensive metabolic panel, blood culture, urine culture, and chest x-ray. Infants meeting higher-risk criteria also showed decreases in invasive testing (P = 0.02). Admission to the hospital and ED lengths of stay decreased in the post-American Academy of Pediatrics statement cohort (P less then 0.001 and P = 0.007, respectively). There were no increases in readmissions or repeat ED visits. CONCLUSIONS This study revealed significant reduction in invasive testing, shorter lengths of ED stays, and lower admission rates at a tertiary care children's hospital after the release of the American Academy of Pediatrics BRUE guideline with no increase in return ED visits or readmissions.OBJECTIVES The purpose of this study is to describe the demographics and clinical characteristics of patients referred to a pediatric emergency department (ED) for unintentional poisoning exposures by a poison control center (PCC) compared with patients/caregivers who self-refer. METHODS The electronic data warehouse at a pediatric hospital was queried from October 1, 2014, to September 30, 2015, for unintentional poisoning-related ED visits and subsequent inpatient admissions. Eligible patients aged 18 years and younger were identified by International Classification of Diseases, Ninth Revision, Clinical Modification codes for pharmaceuticals, non-pharmaceuticalchemicals, fumes/vapors, foreign bodies, adverse food reactions, food poisoning, and bites/stings. Referral classification (PCC referral vs self-refer) was determined by PCC and hospital medical records.Descriptive statistics were used to characterize the patient demographics and ED visits by referral classification and age group. Simple and multiple ents, caregivers, and health care professionals.INTRODUCTION Cranial vault remodeling is commonly associated with high blood loss and high transfusion rates. Blood management protocols have recently been developed to minimize blood loss and reduce transfusion requirements. We sought to determine risk factors associated with blood product transfusion for infants undergoing primary cranial vault remodeling after the implementation of a blood management protocol. METHODS A retrospective review of patients who underwent cranial vault remodeling at a single center was performed. Patients under 18 months of age who underwent cranial vault remodeling after the establishment of a blood management protocol were included. https://www.selleckchem.com/products/roc-325.html RESULTS Thirty-five patients were identified. Eleven patients (31%) received allogenic blood transfusions. Patients who received allogenic blood transfusions had a lower absolute weight (8.8 kg versus 9.6kg P = 0.04), longer procedure times (337 minutes versus 275 minutes P  0.05). CONCLUSION Low weight, longer operative times, and fronto orbital advancement are associated with allogenic blood transfusion despite the use of a blood management protocol.
