NR-2 antikor peptid düzeyinin akut iskemik inmede tanı, prognoz ve koma skorları ile ilişkisi var mıdır?

Aim: This study aimed to demonstrate the diagnostic and prognostic value of NR-2 peptides as a biomarker in acute ischemic stroke and to evaluate their correlation with the Glasgow Coma Scale (GCS) and the National Institutes of Health Stroke Scale (NIHSS).Materials and Methods: The importance of NR-2 peptide level in diagnosis and prognosis in acute stroke was investigated cross-sectional and prospectively. The study included 101 patients, who presented to a tertiary healthcare facility and were diagnosed with acute stroke, and 57 healthy controls. In the whole study population, serum NR-2 peptide levels were measured using the ELISA method.Results: The NR-2 peptide level was 6.32 ± 8.30 in the patient group and 3.91 ± 1.64 in the study group. The NR-2 peptide level was significantly higher in the patient group (p = 0.006). No correlation was detected between NR-2 peptide levels and scores in the GCS or NIHSS. The results indicated that NR-2 was a potential biomarker elevated in the early phase of acute stroke, but had no correlation with the prognosis of acute stroke.Conclusion: Although our data shed light on the use of the NR-2 peptide level as a biomarker in the acute phase in patients with stroke, data are insufficient to predict prognosis. We think that larger, multicenter studies with longer follow-up periods are needed.

Effects of hydrophilic polymer-embedded membrane on permeability and cell adhesion during continuous hemofiltration

Background and AimsClotting within the membrane and/or venous ‘air trap’ chamber is common problems during continuous blood purification therapy. Frequent clotting during continuous blood purification therapy leads to inadequate solute removal, an increased circuit and filter cost, and an increased burden for the medical staff. Improvements in filter membrane materials may reduce the extent of clotting and prolong the filter life. The purpose of the present study was to clarify the characteristics of an NV polymer-embedded membrane (NV-PS) after long-term use, especially the adhesiveness of blood cells and changes in the solute removal performance.MethodsContinuous hemofiltration (CHF) experiments using a permeate recycle mode were performed for 24 h using the same porcine whole blood divided into two portions to compare the NV-PS with a conventional polysulfone membrane (PS). The activated clotting time was adjusted to within a range of 300–400 s. The change in the dextran sieving coefficient (SC) of the membrane and the residual blood clots in the filters were evaluated after the completion of the CHF experiment.ResultsThe increase in the transmembrane pressure and the pressure drop of the hemofilter were significantly smaller using the NV-PS than with the PS. For larger molecules (SC leqq 0.4), the reduction in SC after blood contact was significantly smaller for the NV-PS. Fewer blood cells remained in the residual blood clots when the NV-PS was used.ConclusionNV-PS has the advantages of showing a lower degree of reduction of the solute removal performance and also a lower degree of clogging of the hollow fibers during prolonged circulation. These characteristics may be expected to be advantageous when this membrane is used for continuous blood purification therapy in acute-phase patients.

Evaluation of severe adverse events during rehabilitation for acute-phase patients: A retrospective cohort study.

Early mobilization decreases the likelihood of negative outcomes for acute-phase inpatients. Adverse events occurring during intensive care unit rehabilitation have previously been reported; however, no study has reported the incidence rates for adverse events during the acute rehabilitation phase. This study aimed to investigate the incidence of severe adverse events during acute-phase rehabilitation and evaluate them in detail.Reports of adverse events occurring during acute-phase rehabilitation in a university hospital from April 1, 2011 to March 31, 2018 were retrospectively assessed.Nine severe adverse events occurred during this period (incidence rate, 0.032%), comprising 2 cardiopulmonary arrests, 2 pulseless electrical activity events, 2 deterioration in consciousness events, 1 deterioration in consciousness event due to cerebral infarction, 1 fracture due to a fall, and 1 event involving removal of a ventricular drain. Pulmonary thromboembolism was implicated in 1 adverse event involving pulseless electrical activity and 1 deterioration in consciousness event. The causes for the 6 other adverse events could not be identified. The mean days from admission and the onset of rehabilitation to adverse event occurrence were 22.0 ± 18.2 and 17.9 ± 13.5 days (mean ± standard deviation), respectively. Four of 9 patients died, and 5 patients were discharged home or transferred to other stepdown facilities. When assessed retrospectively, there were no conflicts between patient conditions and the cancellation criteria of rehabilitation by the Japanese Association of Rehabilitation Medicine.The occurrences of severe adverse event may not be related to early mobilization (or onset time of rehabilitation) and compliance status of cancellation criteria.

Minimal clinically important difference of the Berg Balance Scale and comfortable walking speed in patients with acute stroke: A multicenter, prospective, longitudinal study

Objective To determine the minimal clinically important difference between the Berg Balance Scale and comfortable walking speed in acute-phase stroke patients. Design Multicenter, prospective, longitudinal study. Setting Inpatient acute stroke rehabilitation. Subjects Seventy-five patients with acute stroke, mean (SD) age 71.7 (12.2) years. Intervention Inpatients with acute stroke were assessed with the Berg Balance Scale and comfortable walking speed before and after rehabilitation. Physiotherapy was conducted to improve balance and gait over a 2-week period: an average of 40 min/day on weekdays and 20 min/day on weekends and holidays. Main measures The patients’ Berg Balance Scale, comfortable walking speed, Global Rating of Change scale (patient-rated and physiotherapist-rated), and motor score of the Functional Independence Measure were obtained. Minimal clinically important differences were estimated using both anchor- (receiver operating characteristic curves and change difference) and distribution-based approaches (minimal detectable change and 0.5× the change score [SD]). Results The baseline scores were 31.2 (18.9) for the Berg Balance Scale and 0.79 (0.35) m/s for comfortable walking speed. The minimal clinically important difference in the Berg Balance Scale was 6.5–12.5 points by the anchor-based approach and 2.3–4.9 points by the distribution-based approach. The minimal clinically important difference in comfortable walking speed was 0.18–0.25 m/s by the anchor-based and 0.13–0.15 m/s by the distribution-based approach. Conclusions A change of 6.5–12.5 points in the Berg Balance Scale and 0.18–0.25 m/s in the comfortable walking speed is required in these measurements’ anchor-based minimal clinically important differences to be beyond measurement error, and to be perceptible by both patients and clinicians.

Lethal ventricular arrhythmia can be prevented by adjusting the dialysate potassium concentration and the use of anti-arrhythmic agents: a case report and literature review

BackgroundHypokalemia is common in patients with malnutrition undergoing hemodialysis and is often involved in the development of lethal arrhythmia. Moreover, hemodialysis therapy decreases the serum potassium concentration due to potassium removal to the dialysate. However, it is difficult to adjust the dialysate potassium concentration owing to the use of the central dialysate delivery system in Japan. Here, we have presented a case undergoing hemodialysis with dialysate potassium concentration adjustment to prevent ventricular arrhythmia.Case presentationA 56-year-old man with Emery-Dreifuss muscular dystrophy and chronic heart failure was admitted to our hospital and needed subsequent hemodialysis therapy due to renal dysfunction. During hemodialysis, the cardiac resynchronization therapy defibrillator was activated to the treatment of his lethal ventricular arrhythmia. Decreases in serum potassium concentration after hemodialysis and changes in serum potassium concentration during HD were considered the causes of lethal ventricular arrythmia. Therefore, along with using anti-arrhythmic agents, the dialysate potassium concentration was increased from 2.0 to 3.5 mEq/L to minimize changes in the serum potassium concentration during hemodialysis. Post-dialysis hypokalemia disappeared and these changes during hemodialysis were minimized, and no lethal ventricular arrhythmia occurred thereafter.ConclusionsIn this case, we prevented lethal arrhythmia by maintaining the serum potassium concentration by increasing the dialysate potassium concentration, in addition to the use of anti-arrhythmic agents. In the acute phase of patients with frequent lethal arrhythmia undergoing hemodialysis, an increase in dialysate potassium concentration may be an effective method for preventing arrhythmogenic complications.

Development and Trial of a Prototype Device for Sensorimotor Therapy in Patients with Distal Radius Fractures

This study examined the clinical feasibility of a prototype device (development name: Ghost) for facilitating range of motion (RoM) recovery in the acute phase in patients with distal radius fractures (DRF). The Ghost device involves the administration of a combination of vibratory and visual stimuli. We divided the patients into the Ghost (n = 10) and control group (n = 4; tendon vibration only) groups. The experimental interventions were administered between the day after surgery and day 7 postoperatively. Traditional hand therapy was provided to both groups once daily from day 7 until day 84 postoperatively and once a week from day 84 until the end of the intervention period. Because vibratory stimulation makes the patient focus on wrist flexion, the primary outcome was the arc of wrist flexion-extension on the injured side, which was measured on days 7, 14, 28, 42, 56, 70, and 84. Analysis of covariance was applied using a bootstrap method to evaluate changes over time and compare them between the groups. Analyses was performed after stratification by age and body mass index. Both interventions improved RoM over time in patients with DRF. Results showed that Ghost has greater efficacy for improving wrist RoM in DRF patients than vibration alone. Treatment with Ghost can result in good RoM improvement during the acute phase of DRF in young patients and those with and normal or low body mass index. Further study is needed to verify our findings and assess the extent of RoM recovery.

Longitudinal Plasma Proteomics Analysis Reveals Novel Candidate Biomarkers in Acute COVID-19.

The host response to COVID-19 pathophysiology over the first few days of infection remains largely unclear, especially the mechanisms in the blood compartment. We report on a longitudinal proteomic analysis of acute-phase COVID-19 patients, for which we used blood plasma, multiple reaction monitoring with internal standards, and data-independent acquisition. We measured samples on admission for 49 patients, of which 21 had additional samples on days 2, 4, 7, and 14 after admission. We also measured 30 externally obtained samples from healthy individuals for comparison at baseline. The 31 proteins differentiated in abundance between acute COVID-19 patients and healthy controls belonged to acute inflammatory response, complement activation, regulation of inflammatory response, and regulation of protein activation cascade. The longitudinal analysis showed distinct profiles revealing increased levels of multiple lipid-associated functions, a rapid decrease followed by recovery for complement activation, humoral immune response, and acute inflammatory response-related proteins, and level fluctuation in the regulation of smooth muscle cell proliferation, secretory mechanisms, and platelet degranulation. Three proteins were differentiated between survivors and nonsurvivors. Finally, increased levels of fructose–bisphosphate aldolase B were determined in patients with exposure to angiotensin receptor blockers versus decreased levels in those exposed to angiotensin-converting enzyme inhibitors. Data are available via ProteomeXchange PXD029437.

Alternation of the Autonomic Nervous System Is Associated With Pulmonary Sequelae in Patients With COVID-19 After Six Months of Discharge.

Previous studies suggest that autonomic dysfunction is associated with disease severity in acute phase in patients with coronavirus disease 2019 (COVID-19). However, the association between autonomic dysfunction and pulmonary sequelae in patients with COVID-19 is unknown. We conducted a prospective study to investigate the association between autonomic dysfunction and pulmonary sequelae in patients with COVID-19 discharged for 6 months. We included 40 eligible participants and collected the following indicators: heart rate variability (HRV), pulmonary function tests (PFTs), lung X-ray computed tomography (CT), routine blood parameters, liver function parameters, and lymphocyte subsets. We found that at 6 months post-discharge, HRV still had a tight correlation with pulmonary fibrosis. There was a significant difference in HRV between patients with and without diffusion dysfunction, but HRV did not differ between patients with or without ventilatory dysfunction. Diffusion dysfunction and pulmonary fibrosis were tightly associated, and HRV index changes in patients with diffusion dysfunction had the same trend as that of patients with pulmonary fibrosis. They had a lower standard deviation of NN intervals (SDNN), the standard deviation of the average NN intervals (SDANN), and the triangular index, but a higher ratio between LF and HF power (LF/HF). In addition, WBC, neutrophils, and CD4/CD8 were correlated with pulmonary fibrosis and HRV. We concluded that autonomic dysfunction is closely associated with pulmonary fibrosis and diffusion dysfunction, and immune mechanisms may potentially contribute to this process.

Optic Nerve Sheath Diameter Detects Intracranial Hypertension in Acute Malignant Middle Cerebral Artery Infarction

ObjectivesTo evaluate optic nerve sheath diameter in the acute phase of patients with malignant ischemic middle cerebral artery stroke submitted or not to decompressive craniectomy surgery. Materials and MethodsForty patients participated in the study and were evaluated bilaterally by ultrasound on admission and at 24h, 48h and 72 h after admission. Optic nerve sheath diameter values were correlated with tomographic and/or clinical criteria compatible with severe intracranial hypertension. ResultsA Receiver Operating Characteristic curve was drawn for each eye, determining a cut-off value for severe intracranial hypertension in the right eye of 5.4 mm (sensitivity: 62%; specificity: 100%; AUC: 0.82) and in the left eye 5.4 mm (sensitivity: 76%; specificity: 84%; AUC: 0.77). In patients undergoing craniectomy, there was a decrease in the mean value of 1.04mm in the right eye (pre: 5.84 ± 0.47 mm; post: 4.80 ± 0.84 mm; p = 0.001), while in the left, it decreased around 0.86mm (pre: 5.59 ± 0.69 mm; post: 4.73 ± 0.74 mm; p = 0.003). Patients with fatal outcome showed a persistent high mean ocular nerve sheath diameter. ConclusionsMonitoring optic nerve sheath by ultrasound can be considered a reliable method for identifying severe intracranial hypertension in patients with large vessel occlusion, as well as for monitoring patients undergoing craniectomy. Additional studies will be necessary to include this parameter in craniectomy indication algorithms in the future.

Hyperinflammatory environment drives dysfunctional myeloid cell effector response to bacterial challenge in COVID-19.

COVID-19 displays diverse disease severities and symptoms including acute systemic inflammation and hypercytokinemia, with subsequent dysregulation of immune cells. Bacterial superinfections in COVID-19 can further complicate the disease course and are associated with increased mortality. However, there is limited understanding of how SARS-CoV-2 pathogenesis and hypercytokinemia impede the innate immune function against bacterial superinfections. We assessed the influence of COVID-19 plasma hypercytokinemia on the functional responses of myeloid immune cells upon bacterial challenges from acute-phase COVID-19 patients and their corresponding recovery-phase. We show that a severe hypercytokinemia status in COVID-19 patients correlates with the development of bacterial superinfections. Neutrophils and monocytes derived from COVID-19 patients in their acute-phase showed an impaired intracellular microbicidal capacity upon bacterial challenges. The impaired microbicidal capacity was reflected by abrogated MPO and reduced NETs production in neutrophils along with reduced ROS production in both neutrophils and monocytes. Moreover, we observed a distinct pattern of cell surface receptor expression on both neutrophils and monocytes, in line with suppressed autocrine and paracrine cytokine signaling. This phenotype was characterized by a high expression of CD66b, CXCR4 and low expression of CXCR1, CXCR2 and CD15 in neutrophils and low expression of HLA-DR, CD86 and high expression of CD163 and CD11b in monocytes. Furthermore, the impaired antibacterial effector function was mediated by synergistic effect of the cytokines TNF-α, IFN-γ and IL-4. COVID-19 patients receiving dexamethasone showed a significant reduction of overall inflammatory markers in the plasma as well as exhibited an enhanced immune response towards bacterial challenge ex vivo. Finally, broad anti-inflammatory treatment was associated with a reduction in CRP, IL-6 levels as well as length of ICU stay and ventilation-days in critically ill COVID-19 patients. Our data provides insights into the transient functional dysregulation of myeloid immune cells against subsequent bacterial infections in COVID-19 patients and describe a beneficial role for the use of dexamethasone in these patients.

Nutritional Risk Indicators for Predicting a Change in Quadriceps Muscle Thickness in Acute Patients with Stroke.

Introduction: To date, no studies have assessed the prognostic ability of nutritional indicators to predict changes in quadriceps muscle thickness (QMT). Hence, this study aimed to identify the optimal nutritional indicators for predicting the change in QMT during the acute phase in patients with stroke. Methods: This retrospective cohort study was a post-hoc analysis of a prospective study in a single hospital. The Geriatric Nutritional Risk Index (GNRI), Controlling Nutritional Status (CONUT), and Mini Nutritional Assessment - Short Form (MNA-SF) were assessed. The primary outcome was the 2-week change in QMT from the time of admission in the paralytic and non-paralytic sides. QMT was evaluated at the rectus femoris and the vastus intermedius in both lower limbs using B-mode ultrasound imaging. The sum of both measurements was defined as QMT. Univariate and multivariate analyses were performed to confirm the effects of nutritional risks assessed by each nutritional indicator on QMT change. Results: We analyzed 118 patients (mean age, 80.2 ± 8.8 years). No significant difference was found in QMT change in the non-paralytic limbs between the groups stratified based on GNRI and CONUT. However, the difference was significant between the malnourished and normal nutritional status in patients categorized by MNA-SF. After adjusting for potential confounders, a significant association was found between MNA-SF and change in QMT (malnourished vs. normal nutritional status; B = −0.143; 95% confidence interval [CI], −0.254 to −0.031) in the non-paralytic limbs. MNA-SF was not independently associated with change in QMT in the paralytic limb. Furthermore, GNRI and CONUT were not independently associated with change in QMT in both paralytic and non-paralytic limbs. Conclusions: Although MNA-SF might be useful for predicting the QMT change in non-paralytic limbs, GNRI and CONUT cannot predict the QMT change in either the paralytic or non-paralytic limb.

Phase Angle as an Indicator of Baseline Nutritional Status and Sarcopenia in Acute Stroke

ObjectivesThis study aimed to investigate whether phase angle is an indicator of malnutrition and sarcopenia in acute-phase stroke patients. Materials and MethodsWe conducted a retrospective observational study of stroke patients in a single acute-care hospital. The phase angle was measured within 5 days after admission, and the correlation between nutritional status and sarcopenia index was investigated. The cut-off point that distinguishes malnutrition and sarcopenia was evaluated using the receiver operating characteristic curve. The effects of the geriatric nutritional risk index (GNRI) and sarcopenia on the phase angle were examined using multivariate linear regression analysis. ResultsA total of 211 stroke patients (140 men) with a median age of 74 (65–83) were included in the analysis. Malnutrition was present in 38 (18.0%) patients, and 65 (30.8%) had sarcopenia. The phase angle significantly correlated with GNRI, grip strength, skeletal muscle musss index, and calf circumference in both men and women. The cut-off points for discriminating malnutrition were 5.05 for men and 3.96 for women, while the cut-off points for discriminating sarcopenia were 5.28 for men and 4.62 for women. Multivariate linear regression analysis showed that the GNRI and sarcopenia were independently related to the phase angle. ConclusionsPhase angle is a useful indicator for distinguishing malnutrition and sarcopenia in patients with acute stroke.

Hepatitis E Virus Quasispecies in Cerebrospinal Fluid with Neurological Manifestations.

Hepatitis E virus (HEV) infection can lead to a variety of neurological disorders. While HEV RNA is known to be present in the central nervous system, HEV quasispecies in serum and cerebrospinal fluid (CSF) have rarely been explored. We studied the virus’ quasispecies in the blood and the CSF of five patients at the onset of their neurological symptoms. The samples of three patients suffering from meningitis, neuralgic amyotrophy and acute inflammatory polyradiculoneuropathy were taken at the acute phase of the HEV infection. The samples from the other two patients were taken during the chronic phase (5 years after HEV diagnosis) when they presented with clinical signs of encephalitis. We sequenced at least 20 randomly polyproline regions of the selected virus clones. Phylogenetic analysis of the virus variants in the blood and the CSF revealed no virus compartmentalization for the three acute-phase patients but there was clear evidence of HEV quasispecies compartmentalization in the CSF of the two patients during chronic infection. In conclusion, prolonged infection in the immunocompromised condition can lead to independent virus replication in the liver and the tissues, producing viruses in CSF.

Incomplete Systemic Recovery and Metabolic Phenoreversion in Post-Acute-Phase Nonhospitalized COVID-19 Patients: Implications for Assessment of Post-Acute COVID-19 Syndrome.

We present a multivariate metabotyping approach to assess the functional recovery of nonhospitalized COVID-19 patients and the possible biochemical sequelae of “Post-Acute COVID-19 Syndrome”, colloquially known as long-COVID. Blood samples were taken from patients ca. 3 months after acute COVID-19 infection with further assessment of symptoms at 6 months. Some 57% of the patients had one or more persistent symptoms including respiratory-related symptoms like cough, dyspnea, and rhinorrhea or other nonrespiratory symptoms including chronic fatigue, anosmia, myalgia, or joint pain. Plasma samples were quantitatively analyzed for lipoproteins, glycoproteins, amino acids, biogenic amines, and tryptophan pathway intermediates using Nuclear Magnetic Resonance (NMR) spectroscopy and mass spectrometry. Metabolic data for the follow-up patients (n = 27) were compared with controls (n = 41) and hospitalized severe acute respiratory syndrome SARS-CoV-2 positive patients (n = 18, with multiple time-points). Univariate and multivariate statistics revealed variable patterns of functional recovery with many patients exhibiting residual COVID-19 biomarker signatures. Several parameters were persistently perturbed, e.g., elevated taurine (p = 3.6 × 10–3 versus controls) and reduced glutamine/glutamate ratio (p = 6.95 × 10–8 versus controls), indicative of possible liver and muscle damage and a high energy demand linked to more generalized tissue repair or immune function. Some parameters showed near-complete normalization, e.g., the plasma apolipoprotein B100/A1 ratio was similar to that of healthy controls but significantly lower (p = 4.2 × 10–3) than post-acute COVID-19 patients, reflecting partial reversion of the metabolic phenotype (phenoreversion) toward the healthy metabolic state. Plasma neopterin was normalized in all follow-up patients, indicative of a reduction in the adaptive immune activity that has been previously detected in active SARS-CoV-2 infection. Other systemic inflammatory biomarkers such as GlycA and the kynurenine/tryptophan ratio remained elevated in some, but not all, patients. Correlation analysis, principal component analysis (PCA), and orthogonal-partial least-squares discriminant analysis (O-PLS-DA) showed that the follow-up patients were, as a group, metabolically distinct from controls and partially comapped with the acute-phase patients. Significant systematic metabolic differences between asymptomatic and symptomatic follow-up patients were also observed for multiple metabolites. The overall metabolic variance of the symptomatic patients was significantly greater than that of nonsymptomatic patients for multiple parameters (χ2p = 0.014). Thus, asymptomatic follow-up patients including those with post-acute COVID-19 Syndrome displayed a spectrum of multiple persistent biochemical pathophysiology, suggesting that the metabolic phenotyping approach may be deployed for multisystem functional assessment of individual post-acute COVID-19 patients.

Effectiveness of two rehabilitation treatments in the modulation of inflammation during the acute phase in patients with knee prostheses and assessment of the role of the diet in determining post-surgical inflammation

Clinical trial numberNCT04580069. BackgroundTotal knee arthroplasty is associated with an elevated inflammatory response both at a local and systemic level. The main objective of this study is to demonstrate the effectiveness of lymphatic drainage and connective tissue techniques in modulating systemic inflammation. Another objective is to evaluate the existence, at baseline, of a correlation between the inflammation indices and the level of adherence to the Mediterranean diet. Methods34 patients were recruited, and divided into three groups. The control group followed the normal rehabilitation protocol. The other two groups were subjected, in addition to the standard treatment, to manual lymphatic drainage treatment or connective tissue techniques. The outcomes were recorded in three stages: upon entering the hospital, 1 week after entry and at follow-up 21 days after surgery. ResultsThe results of the study showed that both methods, compared with the standard treatment only, positively influenced the final outcomes. In regard to the systemic inflammation, lymphatic drainage and connective techniques showed equal efficacy and similar timing in modulating ESR, while they differ in how they affect CRP. With regard to the local inflammation, the effectiveness of both methods was confirmed with some differences in the location. Finally, analysis of the correlation between inflammatory T0 indices and adherence to the Mediterranean diet showed that patients with higher adhesion index have on average lower PCR, EDO and EDU values. ConclusionsThe post-surgical inflammatory pattern can be positively modified by the rehabilitation methods analyzed, albeit with different methodologies and timing.The influence of the diet on inflammatory parameters, although less evident, seems to show encouraging results worth of further studies.

Autoimmune encephalitis after Japanese encephalitis in children: A prospective study

ObjectiveTo explore anti-neuronal surface antibodies and identify associated serum predictors of autoimmune encephalitis after Japanese encephalitis (JE). MethodsThis prospective study first detected anti-neuronal surface antibodies and cytokines in the serum and cerebrospinal fluid (CSF) of JE patients within one week of symptom onset. Anti-neuronal surface antibodies and cytokines in the serum were detected on day 21 post-JE. If the patients relapsed during the convalescent phase, we simultaneously detected JE virus RNA and cytokines in the CSF, as well as anti-neuronal surface antibodies in the serum and CSF. ResultsAll 31 patients were negative for anti-neuronal surface antibodies at the onset of JE in the serum and CSF. During the convalescent phase, five patients developed autoimmune encephalitis (two had anti-N-methyl-d-aspartate receptor [NMDAR] antibodies, one had γ-aminobutyric acid-B receptor [GABABR] antibodies, and two had other antibodies against unknown neuronal surface antigens). Patients who developed autoimmune encephalitis experienced more severe outcomes than those who did not at the one-year follow-up (p = 0.044). The levels of serum CXCL13 and IL-6, as well as CXCL13, BAFF, CXCL10, and MMP-9 in the CSF were increased in the convalescent phase compared to the acute phase in patients who developed autoimmune encephalitis (p < 0.05). ConclusionIn addition to anti-NMDAR antibodies, anti-GABABR antibodies and antibodies against unknown neuronal surface antigens can trigger autoimmune encephalitis following JE. Patients who developed autoimmune encephalitis had a poorer prognosis at the one-year follow-up. Serum CXCL13 may represent a predictor of autoimmune encephalitis after JE.

Treatments of Peyronie's disease with Scutellaria baicalensis and surgery according to the disease course: a single-center retrospective study of 261 patients.

Oral medication therapies are more conventional than other non-surgical therapies in the acute phase of Peyronie's disease (PD). Although the commonly used oral drugs for PD have shown poor or indeterminate outcomes, most patients prefer oral medications. The aim of this study was to evaluate the efficacy and safety of Scutellaria baicalensis extract for treating acute-phase PD patients and examine the practicality of treatment strategies for PD according to the disease course. This retrospective study was performed at our institution from 2005 to 2015 and analyzed the data of 261 patients with PD. The acute-phase PD patients received Scutellaria baicalensis extract for 6 months. After oral treatment, the patients with persistent curvature underwent surgical correction during the stable phase. During this study period, 183 patients received oral treatment with Scutellaria baicalensis, and 78 patients did not. Compared to the untreated patients, treatment with Scutellaria baicalensis had a significant effect in improving the symptoms of acute-phase PD. The mean time required for stabilization also showed a significant statistical difference. Treatment with Scutellaria baicalensis was safe and well-tolerated. After the disease stabilized, 70 and 31 patients with significant penile curvature underwent surgical correction by 16- dot plication and great saphenous vein grafting procedures, respectively. At the one-year follow-up, complete penile straightening and penile length shortening were observed in 92.86% and 41.43% of the patients after 16-dot plication and in 87.10% and 25.81% of the patients after grafting procedures, respectively. The postoperative Erectile Function domain of the International Index of Erectile Function scales were maintained in all patients after the 16-dot plication procedure and decreased in 54.84% of the patients after the grafting procedure. Overall, 92.86% and 83.87% of the patients who received 16-dot plication and grafting procedures, respectively, were satisfied with the final surgical results. Treatment with extract of Scutellaria baicalensis seems to be beneficial for improvements in symptoms of acute phase PD and acceleration of the disease stabilization. The 16-dot plication and great saphenous vein grafting procedure seem effective options in the surgical management of the stable phase after Scutellaria baicalensis administration in the acute phase of PD.

Staged treatment protocol for gait with hybrid assistive limb in the acute phase of patients with stroke

ABSTRACT Hybrid Assistive Limb (HAL) is a wearable human assistant cyborg-type robot that helps lower-leg movement based on bioelectrical signals detected from the voluntary movement of the person wearing it. In this study, we developed a novel staged HAL treatment protocol for patients with acute stroke. The Regain Program for Gait with HAL (RPG-HAL) was formulated in four steps, based on the severity of limb paralysis. Twenty-one patients with acute stroke received a combination treatment of RPG-HAL and conventional rehabilitation. The feasibility and safety of RPG-HAL were evaluated based on changes in physical function and activities of daily living (ADL). RPG-HAL yielded improvement in gait speed, cadence, step length, and functional ambulation category (FAC). The effect size was >0.8 in all measurements. FAC (1.90) and Barthel Index (BI) (1.92) exhibited the highest scores. Twelve out of 14 patients with FAC 0 before RPG-HAL reached the upper FAC. Thus, earlier intervention using RPG-HAL as improving physical function, ADL, and gait ability in patients with stroke.
