RESUMO

INTRODUCTION: This study aimed to describe the long-term efficacy and safety of upadacitinib and adalimumab through 228 weeks following immediate switch to the alternate therapy with a different mechanism of action (MoA) in patients with rheumatoid arthritis (RA) not achieving treatment goals with their initial randomized therapy in the ongoing phase 3 SELECT-COMPARE study. METHODS: Patients with non-response or incomplete response to initially prescribed upadacitinib 15 mg once daily or adalimumab 40 mg every other week were switched to the alternate therapy by week 26. Efficacy was evaluated through 228 weeks post-switch using validated outcome measures, including Clinical Disease Activity Index (CDAI) low disease activity (LDA; ≤ 10)/remission (≤ 2.8); 28-joint Disease Activity Score based on C-reactive protein ≤ 3.2/< 2.6; ≥ 20%/50%/70% improvement in American College of Rheumatology (ACR) response criteria; and change from baseline in ACR core components. Data are reported as observed. Safety was assessed by treatment-emergent adverse events (TEAEs) through week 264. RESULTS: Of patients initially randomized to upadacitinib and adalimumab, 38.7% and 48.6%, respectively, switched to the alternate therapy by week 26. Clinically relevant improvements in all efficacy measures were observed through 228 weeks post-switch and were generally similar between groups, with small numeric differences mostly in favor of switching to upadacitinib. CDAI remission was achieved by 32.7% and 28.6% of initial non-responders, and 27.5% and 27.3% of incomplete responders, while CDAI LDA was achieved by 76.9% and 72.9% of non-responders, and 72.5% and 72.7% of incomplete responders switching to upadacitinib and to adalimumab, respectively. TEAE rates were similar between groups, although herpes zoster infection, lymphopenia, and creatine phosphokinase elevation were more frequent when switching to upadacitinib. No new safety signals were identified. CONCLUSION: Switching to a different MoA may provide long-term benefit to patients with RA not achieving treatment goals with their initial therapy, with acceptable safety profiles. TRIAL REGISTRATION: NCT02629159.

RESUMO

BACKGROUND: The blood-brain barrier (BBB) is a complex and dynamic structure that serves as a gatekeeper, restricting the migrations of most compounds and molecules from blood into the central nervous system (CNS). The BBB plays a crucial role in maintaining CNS physiological function and brain homeostasis. It can protect the CNS from the entrance of toxic and infectious agents, however, it also restricts the drug permeation into brain to play a therapeutic role. The BBB has been the biggest limiting hurdle to medications entering the brain excluding from the brain about 100% of large-molecule and more than 98% of all small-molecule neurotherapeutics. As a result, it is of inability for drug molecule to reach requisite concentrations within the brain. OBJECTIVE: With the aim of enhancing drug permeability and efficacy, a variety of strategies have been developed: invasive approaches, such as intraarterial delivery, intrathecal delivery, or administrating directly the drug intraventricularly and intracerebrally; non-invasive approaches that take advantage of innate BBB functions, using prodrugs, focused ultrasound, intranasal administration or nanotechnology. CONCLUSIONS: Here we mainly review recent developments and challenges related to non-invasive BBB-crossing techniques, whose benefits include higher efficacy, easier application, less treatment burden, better patient acceptability, and adherence. Additionally, we also analyze the potential of non-invasive methods in the treatment of CNS disorders and render them as a most suitable platform for the management of neurological diseases.

RESUMO

Guillain-Barré syndrome (GBS) is an acute inflammatory polyradiculoneuropathy; a disease involving the peripheral nervous system which is the most common cause of acute flaccid paralysis worldwide. So far, it is still lack of a comprehensive overview and understanding of the national epidemiological, clinical characteristics, and the risk factors of GBS in China, as well as differences between China and other countries and regions in these respects. With the global outbreak of the coronavirus disease 2019 (COVID-19), an epidemiological or phenotypic association between severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection and GBS has attracted great attention. In this review, we outlined the current clinical data of GBS in China by retrieving literature, extracting and synthesizing the data of GBS in China from 2010 to 2021. Besides, we compared the characteristics of epidemiology, preceding events and clinical profiles of GBS between China and other countries and regions. Furthermore, in addition to conventional intravenous immunoglobulin (IVIG) and plasma exchange (PE) therapy, the potential therapeutic effects with novel medications in GBS, such as complement inhibitors, etc., have become the research focus in treatments. We found that epidemiological and clinical findings of GBS in China are approximately consistent with those in the International GBS Outcome Study (IGOS) cohort. We provided an overall picture of the present clinical status of GBS in China and summarized the global research progress of GBS, aiming to further understand the characteristics of GBS and improve the future work of GBS worldwide, especially in countries with the middle and low incomes.

RESUMO

Guillain-Barré syndrome (GBS) is an immune-mediated inflammatory polyradiculoneuropathy, which commonly leads to a very high level of neurological disability. Especially, after the global outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, the causation between GBS and SARS-CoV-2 infection and the coronavirus disease 2019 (COVID-19) vaccination have aroused widespread concern. In the review, we analyzed the impacts of SARS-CoV-2 infection and COVID-19 vaccination on GBS globally, aiming to further understand the characteristics of GBS associated with COVID-19. Based on the electrophysiological data, patients suffering from GBS related to COVID-19 manifested as an acute inflammatory demyelinating polyneuropathy (AIDP). Moreover, we summarized the current findings, which may evidence GBS linking to SARS-CoV-2 infection and COVID-19 vaccination, and discussed the underlying mechanisms whether and how the SARS-CoV-2 virus and COVID-19 vaccination can induce GBS and its variants.

RESUMO

OBJECTIVES: Evaluate the importance of treatment sequencing in SELECT-COMPARE, assessing potential differences between starting upadacitinib or adalimumab therapy following inadequate MTX response. METHODS: Patients from SELECT-COMPARE were randomized to upadacitinib 15 mg once daily, placebo or adalimumab 40 mg. Per protocol, patients with <20% improvement in tender or swollen joint counts (weeks 14, 18, 22) or failure to achieve Clinical Disease Activity Index (CDAI) low disease activity (LDA) at week 26 were blindly switched from upadacitinib to adalimumab or vice versa. Treatment outcomes, including clinical remission/LDA, physical function, pain and a novel combined endpoint for deep response, were evaluated through 48 weeks and corresponding time-averaged response rates determined. Data were analysed by initial randomized group regardless of any subsequent switch in therapy. RESULTS: This post hoc analysis included 651 patients initially randomized to upadacitinib (of whom 252 switched to adalimumab) and 327 patients initially randomized to adalimumab (of whom 159 switched to upadacitinib). At week 48, patients randomized to either therapy demonstrated similar achievement of most treatment endpoints. Greater improvements in the total time spent in a lower disease state were observed for initial upadacitinib vs initial adalimumab therapy across most clinical and patient-reported outcomes through 48 weeks, and the median time to DAS28(CRP) <2.6/≤3.2 occurred 6-8 weeks earlier among those randomized to upadacitinib. CONCLUSION: Following a modified treat-to-target strategy, rates of CDAI remission/LDA and DAS28(CRP) <2.6/≤3.2 at 48 weeks were similar, regardless of starting therapy. However, patients initially receiving upadacitinib reached treatment targets more quickly and spent more time in clinical targets over the initial 48 weeks of treatment.

RESUMO

INTRODUCTION: The Routine Assessment of Patient Index Data 3 (RAPID3) is a patient-reported outcome tool recommended for the assessment of disease activity in patients with rheumatoid arthritis (RA) in clinical practice. This analysis evaluated the long-term effect of upadacitinib vs. comparators on RAPID3 scores in patients with RA in the phase 3 SELECT clinical trial program. METHODS: This post hoc analysis included data from five randomized controlled trials (RCTs) in patients receiving upadacitinib 15 mg or 30 mg once daily (QD) as monotherapy or in combination with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs). The proportions of patients reporting RAPID3 remission (scores ≤ 3) were assessed at week 60. Correlations between absolute scores for RAPID3 and Clinical Disease Activity Index (CDAI), Simplified Disease Activity Index (SDAI), and 28-joint Disease Activity Score with C-reactive protein (DAS28[CRP]) at week 60 were assessed using Spearman correlation coefficients. RESULTS: A total of 3117 patients were included from the SELECT-NEXT, -BEYOND, -MONOTHERAPY, -COMPARE, and -EARLY trials. By week 60, 32-52% of methotrexate-naïve and csDMARD inadequate responder (IR) patients treated with either upadacitinib 15 mg QD or upadacitinib 30 mg QD reported RAPID3 scores consistent with remission. The proportions were slightly lower in the biologic DMARD-IR SELECT-BEYOND population (19-28%). RAPID3 scores highly correlated (Spearman correlation values ≥ 0.58) with CDAI, SDAI, and DAS28(CRP) scores through week 60 (all p < 0.001). CONCLUSIONS: Upadacitinib, as monotherapy or in combination with csDMARDs, was associated with patient-reported remission assessed by RAPID3 over 60 weeks across the SELECT RCTs in patients with RA. TRIAL REGISTRATION: SELECT-BEYOND (NCT02706847); SELECT-NEXT (NCT02675426); SELECT-MONOTHERAPY (NCT02706951); SELECT-EARLY (NCT02706873); SELECT-COMPARE (NCT02629159).


Rheumatoid arthritis (RA) is a disease that causes inflammation of the joints. Doctors have several ways of assessing how bad a patient's disease is, and these often use a combination of signs and symptoms to develop a 'score'. One method is called RAPID3, which is a score based on an overall assessment of the disease by the patient, the level of pain, and the amount of physical disability. An advantage of RAPID3 is that it is quick and easy to use, and since it uses only patient-reported symptoms, it can be measured easily via telemedicine, without the need for an in-person consultation. In this study, we decided to look into the effect of upadacitinib, a drug used for the treatment of RA, on RAPID3 score in patients with RA. We also investigated whether RAPID3 correlates with other ways of measuring RA severity, including scores that use physician-measured factors such as number of affected joints, as this can help show whether RAPID3 is a valid and useful tool. We found that upadacitinib led to long-term improvements in RAPID3 score, and that results were the same in different studies and patient groups, including patients who had not responded well to other treatments. We also found that RAPID3 correlated well with other measures, i.e., improvements in RAPID3 happened in parallel with improvements in other scores. Overall, these results suggest that RAPID3 can be a useful tool in patients with RA.

RESUMO

INTRODUCTION: In clinical trials with hepatitis C virus-infected treatment-naïve (TN) patients with compensated cirrhosis (CC), glecaprevir/pibrentasvir (G/P), a fixed-dose, once-daily, pangenotypic regimen, has demonstrated sustained virologic response at posttreatment Week 12 (SVR12) > 95%. We evaluated the real-world safety and effectiveness of 8-week G/P therapy in TN patients with CC, including certain subgroups of interest. METHODS: The CREST study is a real-world, noninterventional, multicenter study retrospectively assessing data from Canada, Germany, Israel, Italy, and Spain. The full analysis set (FAS) designated all patients in the study; the modified analysis set (MAS) excluded patients who discontinued G/P for nonvirologic failure or who had missing SVR12 data. The primary endpoint was SVR12; safety endpoints were also assessed. RESULTS: A total of 386 patients were included in the FAS, 375 patients completed the study, and 325 patients were included in the MAS; 51 patients had missing SVR12 data. Overall, in the MAS and FAS, SVR12 was achieved in 99.1% and 84.2% of patients, respectively. In subgroups of interest, the percentage of patients achieving SVR12 in the MAS (and FAS) was: genotype (GT)3: 97.5% (80.6%); FibroScan® ≥ 12.5 kPa: 98.9% (89.3%); platelet count < 100 × 109/l: 100% (88.2%); both platelets < 150 × 109/l and FibroScan® > 20 kPa: 100% (88.9%); aspartate aminotransferase-to-platelet ratio index > 1.09: 98.7% (83.1%); fibrosis-4 index > 3.25: 98.6% (84.0%); albumin < 3 g/dl: 100% (91.7%); people who use drugs: 97.7% (84.3%); psychiatric disorders: 96.6% (84.8%); and human immunodeficiency virus coinfection: 100% (95.0%). Overall, 26.9% (104/386) of patients experienced an adverse event, none of which were classed as serious. CONCLUSION: In this real-world cohort, 8 weeks of G/P therapy was well tolerated in TN patients with CC. SVR12 rates were similar to clinical trials, supporting 8-week treatment in TN patients with CC, including those with signs of advanced liver disease and GT3 infection.

RESUMO

In clinical studies, it is common to have binary outcomes collected over time as repeated measures. This manuscript reviews and evaluates two popular classes of statistical methods for analyzing binary response data with repeated measures: likelihood-based Generalized Linear Mixed Model (GLMM), and semiparametric Generalized Estimating Equation (GEE). Recommendations for choice of analysis model and points to consider for implementation in clinical studies in the presence of missing data are provided based on a comprehensive literature review, as well as, a simulation study evaluating the performance of both GLMM and GEE under scenarios representative of typical clinical trial settings. Under Missing at Random (MAR) assumption, GLMM is preferred over GEE, and the SAS PROC GLIMMIX marginal model is recommended for implementing GLMM in analyzing clinical trial data. When there is an underlying continuous variable used to define the binary response, and the missing proportion is high and/or unbalanced between treatment groups, a two-step approach combining Multiple Imputation (MI) and GEE (MI-GEE) is recommended.

RESUMO

INTRODUCTION: The efficacy of pharmacotherapy and deep brain stimulation of the subthalamic nucleus in treating Parkinson's disease motor symptoms is highly variable and may be influenced by patient genotype. The relatively common (prevalence about one in three) and protein-altering rs6265 single nucleotide polymorphism (C > T) in the gene BDNF has been associated with different clinical outcomes with levodopa. OBJECTIVE: We sought to replicate this reported association in early-stage Parkinson's disease subjects and to examine whether a difference in clinical outcomes was present with subthalamic nucleus deep brain stimulation. MATERIALS AND METHODS: Fifteen deep brain stimulation and 13 medical therapy subjects were followed for 24 months as part of the Vanderbilt DBS in Early Stage PD clinical trial (NCT00282152, FDA IDE #G050016). Primary outcome measures were the Unified Parkinson's Disease Rating Scale (UPDRS) and Parkinson's Disease Questionnaire-39. RESULTS: Outcomes with drug therapy in subjects carrying the rs6265 T allele were significantly worse following 12 months of treatment compared to C/C subjects (UPDRS: +20 points, p = 0.019; PDQ-39: +16 points, p = 0.018). In contrast, rs6265 genotype had no effect on overall motor response to subthalamic nucleus deep brain stimulation at any time point; further, rs6265 C/C subjects treated with stimulation were associated with worse UPDRS part II scores at 24 months compared to medical therapy. CONCLUSIONS: Genotyping for the rs6265 polymorphism may be useful for predicting long-term response to drug therapy and counseling Parkinson's disease patients regarding whether to consider earlier subthalamic nucleus deep brain stimulation. Validation in a larger cohort of early-stage Parkinson's disease subjects is warranted.

RESUMO

BACKGROUND: Upadacitinib (UPA) is an oral Janus kinase (JAK) inhibitor approved for the treatment of rheumatoid arthritis (RA). JAK inhibitors have been associated with an increased risk of herpes zoster (HZ) in patients with RA. OBJECTIVES: To evaluate the incidence and risk factors for HZ in UPA-treated patients with RA from the UPA phase III clinical trial programme. METHODS: Exposure-adjusted incidence/event rates for HZ were determined in patients receiving UPA (monotherapy or combination therapy) in six randomised phase III trials (data cut-off on 30 June 2020). HZ incidence and event rates were also determined in patients receiving methotrexate (MTX) monotherapy or adalimumab (ADA) + MTX. Multivariable Cox regression analysis was used to identify HZ risk factors in UPA-treated patients. RESULTS: A total of 5306 patients were included in this analysis. The incidence rate of HZ/100 patient-years (95% CI) was 0.8 (0.3 to 1.9), 1.1 (0.5 to 1.9), 3.0 (2.6 to 3.5) and 5.3 (4.5 to 6.2), in the MTX monotherapy, ADA + MTX, UPA 15 mg and UPA 30 mg groups, respectively. The majority of HZ cases with UPA (71%) involved a single dermatome. Prior history of HZ and Asian region were HZ risk factors in UPA-treated patients. CONCLUSION: In the UPA phase III RA clinical programme, HZ incidence and event rates were higher with UPA versus ADA + MTX or MTX monotherapy, and higher with the 30 mg versus 15 mg dose. Patients from Asia and those with a history of HZ may be at increased risk of HZ while receiving UPA.

RESUMO

INTRODUCTION: Upadacitinib is a Janus kinase inhibitor with demonstrated efficacy in patients with rheumatoid arthritis (RA). OBJECTIVE: The aim of this study was to assess the long-term safety of upadacitinib in patients with active RA from Japan compared with global clinical trial populations. METHODS: Pooled data in patients enrolled from Japan (the 'Japanese population'; SELECT-SUNRISE, SELECT-EARLY, and SELECT-MONOTHERAPY) were compared with that from global (Japan and ex-Japan) upadacitinib clinical trial populations and summarized descriptively. RESULTS: The Japanese population (mean age 57.0 years; mean RA duration 6.1 years) received upadacitinib 7.5 mg (n = 121), 15 mg (n = 126), and 30 mg (n = 124) once daily, while the global population (mean age 54.8 years; mean RA duration 9.1 years) received upadacitinib 6 mg twice daily/15 mg once daily (n = 2883) and 12 mg twice daily/30 mg once daily (n = 1375). Most patients were female (79.3%). The exposure-adjusted incidence rates (EAIRs) of serious adverse events in the Japanese population were 11.5, 12.2, and 21.2 per 100 patient-years (PY) with upadacitinib 7.5, 15, and 30 mg, respectively. Herpes zoster rates were higher in the Japanese population (7.8, 12.4, and 16.7 per 100 PY with 7.5, 15, and 30 mg, respectively) versus global populations (3.7 and 7.0 per 100 PY with 15 and 30 mg, respectively). Prior herpes zoster was a significant risk factor for herpes zoster. CONCLUSIONS: The safety profile of upadacitinib was generally similar between Japanese and global RA populations, except for higher EAIRs for serious adverse events and infections, including herpes zoster, in the Japanese population.

RESUMO

Kikuchi-Fujimoto disease (KFD), also known as histiocytic necrotizing lymphadenitis, is a rare, benign, self-limiting disease characterized by local lymphadenopathy. Central nervous system involvement in KFD is extremely rare and remains a diagnostic challenge. Only 41 cases of aseptic meningitis associated with KFD have been reported worldwide, with just four cases (including our case) of KFD with meningitis as the first symptom. We report a case of KFD accompanied by aseptic meningitis with severely high intracranial pressure (400 mmH2O), increased white blood cell count (56 × 106/L), and moderately elevated protein level (0.52 g/L). This case is unique in the delayed appearance of lymphadenopathy. After 1 month of treatment with steroids, fever, headache, and lymphadenopathy gradually disappeared, and the result of cerebrospinal fluid examination gradually became normal. In conclusion, based on our case findings and our literature review on KFD with aseptic meningitis, a diagnosis of KFD should be considered when delayed appearance of lymphadenopathy is observed in patients with aseptic meningitis.

RESUMO

Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is a rare inflammatory disorder, mainly involving the brainstem. Posterior reversible encephalopathy syndrome (PRES) is a syndrome that affects the bilateral parietal-occipital region. Here, we describe a rare case of CLIPPERS with PRES. A 47-year-old woman presented with subacute, progressive ataxia symptoms, and radiological and pathological findings were consistent with CLIPPERS. In addition, she had acute convulsions and was unconscious, and brain magnetic resonance imaging fluid-attenuated inversion recovery showed patchy high-intensity posterior cerebral white matter signals, with imaging lesions showing vasogenic oedema, a typical manifestation of PRES. The imaging lesions showed vasogenic oedema in bilateral parietal and occipital lobes and typical 'pepper-like' punctate gadolinium enhancement in pons and bilateral cerebellar hemispheres, which were considered to be caused by merger of CLIPPERS and PRES. Clinical manifestations and imaging lesions disappeared after two months of steroids and symptomatic treatment, supporting the diagnosis of CLIPPERS with PRES. When patients with CLIPPERS show unusual symptoms or atypical vasogenic oedema lesions in the posterior cerebral white matter, the coexistence of PRES should be considered.

RESUMO

OBJECTIVES: To evaluate efficacy and safety of immediate switch from upadacitinib to adalimumab, or vice versa, in patients with rheumatoid arthritis with non-response or incomplete-response to the initial therapy. METHODS: SELECT-COMPARE randomised patients to upadacitinib 15 mg once daily (n=651), placebo (n=651) or adalimumab 40 mg every other week (n=327). A treat-to-target study design was implemented, with blinded rescue occurring prior to week 26 for patients who did not achieve at least 20% improvement in both tender and swollen joint counts ('non-responders') and at week 26 based on Clinical Disease Activity Index (CDAI) >10 ('incomplete-responders') without washout. RESULTS: A total of 39% (252/651) and 49% (159/327) of patients originally randomised to upadacitinib and adalimumab were rescued to the alternate therapy. In both switch groups (adalimumab to upadacitinib and vice versa) and in non-responders and incomplete-responders, improvements in disease activity were observed at 3 and 6 months following rescue. CDAI low disease activity was achieved by 36% and 47% of non-responders and 45% and 58% of incomplete-responders switched to adalimumab and upadacitinib, respectively, 6 months following switch. Overall, approximately 5% of rescued patients experienced worsening in disease activity at 6 months postswitch. The frequency of adverse events was similar between switch groups. CONCLUSIONS: These observations support a treat-to-target strategy, in which patients who fail to respond initially (or do not achieve sufficient response) are switched to a therapy with an alternate mechanism of action and experience improved outcomes. No new safety findings were observed despite immediate switch without washout.

RESUMO

OBJECTIVES: Long-term safety and efficacy of adalimumab among patients with juvenile idiopathic arthritis (JIA) was evaluated through 6 years of treatment. METHODS: Children aged 4-17 years with polyarticular JIA were enrolled in a phase III, randomised-withdrawal, double-blind, placebo-controlled trial consisting of a 16-week open-label lead-in period, 32-week randomised double-blind period and 360-week long-term extension. Patients were stratified by baseline methotrexate use. Adverse events (AEs) were monitored, and efficacy assessments included JIA American College of Rheumatology (JIA ACR) 30%, 50%, 70% or 90% responses and the proportions of patients achieving 27-joint Juvenile Arthritis Disease Activity Score (JADAS27) low disease activity (LDA, ≤3.8) and inactive disease (ID, ≤1). RESULTS: Of 171 patients enrolled, 62 (36%) completed the long-term extension. Twelve serious infections in 11 patients were reported through 592.8 patient-years of exposure. No cases of congestive heart failure-related AEs, demyelinating disease, lupus-like syndrome, malignancies, tuberculosis or deaths were reported. JIA ACR 30/50/70/90 responses and JADAS27 LDA were achieved in 66% to 96% of patients at week 104, and 63 (37%) patients achieved clinical remission (JADAS27 ID sustained for ≥6 continuous months) during the study. Attainment of JIA ACR 50 or higher and JADAS27 LDA or ID in the initial weeks were the best predictors of clinical remission. Mean JADAS27 decreased from baseline, 22.5 (n=170), to 2.5 (n=30) at week 312 (observed analysis). CONCLUSIONS: Through 6 years of exposure, adalimumab was well tolerated with significant clinical response (up to clinical remission) and a relatively low retention rate.

RESUMO

Neuromyelitis optica spectrum disorder (NMOSD) is a common neuroinflammatory demyelinating disease associated with aquaporin-4 (AQP4) antibody in the central nervous system. Neurosyphilis is a neurological disease caused by Treponema pallidum infection. NMOSD commonly occurs concurrently with autoimmune diseases. However, they have rarely been associated with infectious diseases. In this report we describe a rare case of concurrent AQP4-positive NMOSD and neurosyphilis. A 60-year-old man was admitted to our hospital with a complaint of progressive weakness in his legs for one month. T2-weighted magnetic resonance images of the spinal cord showed longitudinal extensive lesions at C7-T7. The rapid plasma reagin test and T. pallidum particle agglutination assay performed using patient serum and cerebrospinal fluid (CSF) were positive. Additionally, the AQP4-immunoglobulin (Ig) G was detected in the serum and CSF. The patient's symptom gradually improved after penicillin and methylprednisolone treatment. This case report highlights the possibility of the presence of an infectious disease in patients with NMOSD.

RESUMO

Urchin-like RuCu nanoparticles and hollow RuCuMo nanoparticles were prepared by a one-pot chemical reduction method. The nanoparticles were characterized by EDX, HRTEM, XPS and ICP-AES. By combining cyclic voltammetry and TEM, the formation process of nanoparticles was obtained. The urchin-like RuCu nanoparticles are proved to be formed via underpotential deposition mechanism and the formation of ternary nanoparticles RuCuMo was due to the replacement of Cu with Ru and the interception of Mo gradually. It was found that the formation of different morphology is depended on the precursors in the reaction system and their reduction sequences. Compared to previously reported multi-step synthetic routes, the developed method here is much simpler.

RESUMO

BACKGROUND: Despite increased secondary cardiovascular events in patients with ischemic cardiomyopathy (ICM), the expression of innate cardiac protective molecules in the hearts of patients with ICM is incompletely characterized. Therefore, we used a nonbiased RNAseq approach to determine whether differences in cardiac protective molecules occur with ICM. METHODS AND RESULTS: RNAseq analysis of human control and ICM left ventricular samples demonstrated a significant decrease in KCNJ11 expression with ICM. KCNJ11 encodes the Kir6.2 subunit of the cardioprotective KATP channel. Using wild-type mice and kcnj11-deficient (kcnj11-null) mice, we examined the effect of kcnj11 expression on cardiac function during ischemia-reperfusion injury. Reactive oxygen species generation increased in kcnj11-null hearts above that found in wild-type mice hearts after ischemia-reperfusion injury. Continuous left ventricular pressure measurement during ischemia and reperfusion demonstrated a more compromised diastolic function in kcnj11-null compared with wild-type mice during reperfusion. Analysis of key calcium-regulating proteins revealed significant differences in kcnj11-null mice. Despite impaired relaxation, kcnj11-null hearts increased phospholamban Ser16 phosphorylation, a modification that results in the dissociation of phospholamban from sarcoendoplasmic reticulum Ca2+, thereby increasing sarcoendoplasmic reticulum Ca2+-mediated calcium reuptake. However, kcnj11-null mice also had increased 3-nitrotyrosine modification of the sarcoendoplasmic reticulum Ca2+-ATPase, a modification that irreversibly impairs sarcoendoplasmic reticulum Ca2+ function, thereby contributing to diastolic dysfunction. CONCLUSIONS: KCNJ11 expression is decreased in human ICM. Lack of kcnj11 expression increases peroxynitrite-mediated modification of the key calcium-handling protein sarcoendoplasmic reticulum Ca2+-ATPase after myocardial ischemia-reperfusion injury, contributing to impaired diastolic function. These data suggest a mechanism for ischemia-induced diastolic dysfunction in patients with ICM.

RESUMO

OBJECTIVE: To determine risk factors associated with tracheostomy placement after severe traumatic brain injury (TBI) and subsequent outcomes among those who did and did not receive a tracheostomy. METHODS: This retrospective cohort study compared adult trauma patients with severe TBI (n = 583) who did and did not receive tracheostomy. A multivariable logistic regression model assessed the associations between age, sex, race, insurance status, admission GCS, AIS (Head, Face, Chest) and tracheostomy placement. Ordinal logistic regression models assessed tracheostomy's influence on ventilator days and ICU LOS. To limit immortal time bias, Cox proportional hazards models assessed mortality at 1, 3 and 12-months. RESULTS: In this multivariable model, younger age and private insurance were associated with increased probability of tracheostomy. AIS, ISS, GCS, race and sex were not risk factors for tracheostomy placement. Age showed a non-linear relationship with tracheostomy placement; likelihood peaked in the fourth decade and declined with age. Compared to uninsured patients, privately insured patients had an increased probability of receiving a tracheostomy (OR = 1.89 [95% CI = 1.09-3.23]). Mortality was higher in those without tracheostomy placement (HR = 4.92 [95% CI = 3.49-6.93]). Abbreviated injury scale-Head was an independent factor for time to death (HR = 2.53 [95% CI = 2.00-3.19]), but age, gender and insurance were not. CONCLUSIONS: Age and insurance status are independently associated with tracheostomy placement, but not with mortality after severe TBI. Tracheostomy placement is associated with increased survival after severe TBI.

RESUMO

Psychogenic nonepileptic seizures (PNES) are a common cause of refractory seizures. Video-electroencephalographic (EEG) monitoring has allowed PNES to be effectively distinguished from epileptic seizures. Once the diagnosis of PNES is established, neurologists face the challenge of explaining it to patients. Patients may not always receive the diagnosis well. The aim of this study is to evaluate how effectively patients receive and perceive the diagnosis of PNES. This prospective study was conducted in an eight-bed epilepsy monitoring unit (EMU). Adult patients with newly confirmed PNES were included. After receiving written consent, a self-administered questionnaire was given to patients after the attending physician had communicated the diagnosis of PNES. A total of 75 patients were recruited. All patients had their typical seizures recorded on video-EEG (range 1-12, mean 2.18). Seventy patients were satisfied with the diagnosis of PNES. Nine patients did not agree that PNES has a psychological cause. Nineteen patients thought that the EMU doctors had no clue as to the cause of their seizures and 20 thought that there was no hope for a cure of their seizures. A significant number of patients with PNES feel that there is no hope for cure of their seizures. Thorough education about PNES, properly preparing patients before discussing the diagnosis of PNES, and preferably earlier diagnosis may prevent this miscommunication and result in better outcomes. A comprehensive approach including psychological counseling and psychiatric input, evaluation and treatment, in order to bring the illness from the subconscious to the conscious level, and effective follow-up may be helpful.
