Impact of Iliac Crest Bone Grafting on Postoperative Outcomes and Complication Rates Following Minimally Invasive Transforaminal Lumbar Interbody Fusion

Objective The relationship between bone graft technique and postoperative outcomes for minimally invasive transforaminal lumbar interbody fusion (MIS TLIF) has not been well-defined. This study aims to determine the effect of iliac crest bone grafting (ICBG) on patient-reported outcomes (PROs) and complication rates following MIS TLIF. Methods Primary, single-level MIS TLIF patients were consecutively analyzed. Patients that prospectively received a percutaneous technique of ICBG were compared to patients that retrospectively received bone morphogenetic protein-2 (BMP-2). Complication rates were assessed perioperatively and up to 1 year postoperatively. Changes in Oswestry Disability Index (ODI), visual analogue scale (VAS) back, and VAS leg pain were compared. Rates of minimum clinically important difference (MCID) achievement at final follow-up for ODI, VAS back, and VAS leg scores were compared. Results One hundred forty-nine patients were included: 101 in the BMP-2 cohort and 48 in the ICBG cohort. The ICBG cohort demonstrated increases in intraoperative blood loss and shorter lengths of stay. ICBG patients also experienced longer operative times, though this did not reach statistical significance. No significant differences in complication or reoperation rates were identified. The ICBG cohort demonstrated greater improvements in VAS leg pain at 6-week and 12-week follow-up. No other significant differences in PROs or MCID achievement rates were identified. Conclusion Patients undergoing MIS TLIF with ICBG experienced clinically insignificant increases in intraoperative blood loss and did not experience increases in postoperative pain or disability. Complication and reoperation rates were similar between groups. These results suggest that ICBG is a safe option for MIS TLIF.
Evaluation of potential health effects associated with occupational and environmental exposure to styrene – an update

ABSTRACT The potential chronic health risks of occupational and environmental exposure to styrene were evaluated to update health hazard and exposure information developed since the Harvard Center for Risk Analysis risk assessment for styrene was performed in 2002. The updated hazard assessment of styrene’s health effects indicates human cancers and ototoxicity remain potential concerns. However, mechanistic research on mouse lung tumors demonstrates these tumors are mouse-specific and of low relevance to human cancer risk. The updated toxicity database supports toxicity reference levels of 20 ppm (equates to 400 mg urinary metabolites mandelic acid + phenylglyoxylic acid/g creatinine) for worker inhalation exposure and 3.7 ppm and 2.5 mg/kg bw/day, respectively, for general population inhalation and oral exposure. No cancer risk value estimates are proposed given the established lack of relevance of mouse lung tumors and inconsistent epidemiology evidence. The updated exposure assessment supports inhalation and ingestion routes as important. The updated risk assessment found estimated risks within acceptable ranges for all age groups of the general population and workers with occupational exposures in non-fiber-reinforced polymer composites industries and fiber-reinforced polymer composites (FRP) workers using closed-mold operations or open-mold operations with respiratory protection. Only FRP workers using open-mold operations not using respiratory protection have risk exceedances for styrene and should be considered for risk management measures. In addition, given the reported interaction of styrene exposure with noise, noise reduction to sustain levels below 85 dB(A) needs be in place.
Self-Adaptive Framework Based on MAPE Loop for Internet of Things †

The Internet of Things (IoT) connects a wide range of objects and the types of environments in which IoT can be deployed dynamically change. Therefore, these environments can be modified dynamically at runtime considering the emergence of other requirements. Self-adaptive software alters its behavior to satisfy the requirements in a dynamic environment. In this context, the concept of self-adaptive software is suitable for some dynamic IoT environments (e.g., smart greenhouses, smart homes, and reality applications). In this study, we propose a self-adaptive framework for decision-making in an IoT environment at runtime. The framework comprises a finite-state machine model design and a game theoretic decision-making method for extracting efficient strategies. The framework was implemented as a prototype and experiments were conducted to evaluate its runtime performance. The results demonstrate that the proposed framework can be applied to IoT environments at runtime. In addition, a smart greenhouse-based use case is included to illustrate the usability of the proposed framework.
Prevalence of Atrial Fibrillation in Patients with Retinal Vessel Occlusion and Its Association: A Systematic Review and Meta-Analysis

ABSTRACT Objective: Recent studies have shown that atrial fibrillation (AF) is more prevalent in patients with retinal vessel occlusion and may be associated with both central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO). However, there is no systematic review and meta-analysis to confirm this finding. Methods: We searched the databases of MEDLINE and EMBASE from inception to January 2019. Included studies were published cohort, case-control or cross-sectional studies, and randomized control trials reporting the prevalence of AF in patients with CRAO or CRVO. Data from each study were combined using the random-effects model. Results: Eleven studies were included in our meta-analysis, involving a total population of 12,305 subjects with retinal vessel occlusion. The prevalence of AF ranged from 4.1% to 21.4% (pooled prevalence = 11.5%, 95% CI: 7.0–16.1, I2 = 96.3%). Five studies reported a control group of patients without retinal vessel occlusion. We found that AF is significantly associated with retinal vessel occlusion (pooled OR = 2.24, 95% CI:2.07–2.43, I2 = 0.0%). Conclusion: Our study showed that AF is significantly associated with retinal vessel occlusion. Further studies are needed to fully elucidate the exact mechanism linking AF with CRAO and CRVO.
Insight into the Role of Extracellular Vesicles in Lysosomal Storage Disorders

Extracellular vesicles (EVs) have received increasing attention over the last two decades. Initially, they were considered as just a garbage disposal tool; however, it has progressively become clear that their protein, nucleic acid (namely miRNA and mRNA), and lipid contents have signaling functions. Besides, it has been established that cells release different types of vesicular structures for which characterization is still in its infancy. Many stress conditions, such as hypoxia, senescence, and oncogene activation have been associated with the release of higher levels of EVs. Further, evidence has shown that autophagic–lysosomal pathway abnormalities also affect EV release. In fact, in neurodegenerative diseases characterized by the accumulation of toxic proteins, although it has not become clear to what extent the intracellular storage of undigested materials itself has beneficial/adverse effects, these proteins have also been shown to be released extracellularly via EVs. Lysosomal storage disorders (LSDs) are characterized by accumulation of undigested substrates within the endosomal–lysosomal system, due either to genetic mutations in lysosomal proteins or to treatment with pharmacological agents. Here, we review studies investigating the role of lysosomal and autophagic dysfunction on the release of EVs, with a focus on studies exploring the release of EVs in LSD models of both genetic and pharmacological origin. A better knowledge of EV-releasing pathways activated in lysosomal stress conditions will provide information on the role of EVs in both alleviating intracellular storage of undigested materials and spreading the pathology to the neighboring tissue.
Global Dimensions of Plant Virus Diseases: Current Status and Future Perspectives.

Viral diseases provide a major challenge to twenty-first century agriculture worldwide. Climate change and human population pressures are driving rapid alterations in agricultural practices and cropping systems that favor destructive viral disease outbreaks. Such outbreaks are strikingly apparent in subsistence agriculture in food-insecure regions. Agricultural globalization and international trade are spreading viruses and their vectors to new geographical regions with unexpected consequences for food production and natural ecosystems. Due to the varying epidemiological characteristics of diverent viral pathosystems, there is no one-size-fits-all approach toward mitigating negative viral disease impacts on diverse agroecological production systems. Advances in scientific understanding of virus pathosystems, rapid technological innovation, innovative communication strategies, and global scientific networks provide opportunities to build epidemiologic intelligence of virus threats to crop production and global food security. A paradigm shift toward deploying integrated, smart, and eco-friendly strategies is required to advance virus disease management in diverse agricultural cropping systems. Expected final online publication date for the Annual Review of Virology Volume 6 is September 30, 2019. Please see http://www.annualreviews. org/page/journal/pubdates for revised estimates.

Association between imbalance of cortical brain activity and successful motor recovery in sub-acute stroke patients with upper limb hemiparesis: a functional near-infrared spectroscopy study.

OBJECTIVE This study was designed to determine the association between motor functional recovery and interhemispheric imbalance in cortical brain activity in sub-cortical stroke patients with moderate-to-severe upper limb hemiparesis admitted to the convalescent rehabilitation ward. SUBJECTS AND METHODS The study included first-ever stroke patients with moderate-to-severe upper limb hemiparesis who received multidisciplinary rehabilitation therapy in the rehabilitation ward. Motor function of the affected upper extremity was evaluated by the Fugl-Meyer assessment and action research arm test at 1 (T1) and 3 months (T2) after stroke onset. We also conducted serial functional near-infrared spectroscopy at the same time points and calculated the laterality index, which is based on changes in oxyhaemoglobin in primary sensorimotor cortex (Brodmann Area 4), pre-motor cortex and supplementary motor cortex (PMC + SMA, BA6). RESULTS The study included eight patients (seven females, mean age: 68.8). Both the Fugl-Meyer assessment and action research arm test scores improved significantly during the study. Laterality index did not change significantly from T1 to T2. There was a no significant correlation between changes in laterality index in each region and improvement in Fugl-Meyer assessment score. In contrast, a significant and negative correlation was noted between ΔLI in Brodmann Area 4 and improvement in action research arm test score. CONCLUSION Our results suggested that activation of the non-lesional hemisphere in sub-acute stroke associated with motor recovery in moderate-to-severe upper limb hemiparesis. A multidisciplinary rehabilitation of stroke patients with moderate-to-severe upper limb hemiparesis might enhance the compensatory movements and pre-existing motor network from the non-lesional motor cortex.
Characterization of Dendritic Cell(DC)10 in recurrent miscarriage and recurrent implantation failure.

During pregnancy, the maternal immune system must tolerate the persistence of semi-allogeneic fetus in the maternal tissue. Inadequate recognition of fetal antigens may lead to pregnancy complications, such as recurrent miscarriage (RM) and recurrent implantation failure (RIF). Dendritic cells (DCs) are key regulators of protective immune responses and the development and maintenance of tolerance. Regarding that DCs are important in the establishment of immune tolerance in human pregnancy, it would be important to study the microenvironment in which DCs reside or are activated may affect their functions towards tolerance rather than active immune response. IL-10 play a critical role in the maintenance of normal pregnancy, and the increased production of IL-10 is associated with successful pregnancy. In this study, we provide an in-depth comparison of the phenotype and cytokine production by DC-10 and other DC subsets, such as iDC and mDC. CD14+ monocyte-derived DCs were differentiated in the presence of IL-10 (DC-10) in vitro from 10 normal fertile controls, 6 RM women and 7 RIF women, and characterized for relevant markers. DC-10 was characterized by relatively low expression of costimulatory molecule CD86, as well as MHC class II molecule HLA-DR, high expression of tolerance molecules HLA-G, ILT2, ILT4 and immunosuppressive cytokine IL-10, but produced little or no proinflammatory cytokines, such as TNF-α, IL-6 and IL-12p70. Our study provides a better understanding of the phenotypical properties of DC-10, which may participate in the complex orchestration that leads to maternal immune tolerance and homeostatic environment in human pregnancy.
Designing Cellular Structures for Additive Manufacturing Using Voronoi–Monte Carlo Approach

This study aims at reporting a strategy of designing cellular materials based on Voronoi–Monte Carlo approach for additive manufacturing. The approach is implemented to produce a fully connected cellular structure in the design space without producing material discontinuity. The main characteristics of the cellular structure, such as the density and the cell size, are controlled by means of two generation parameters, namely the number of seed points and the relaxation time. The generated cellular structures representing various designs of generated cellular wrenches are converted into surface tessellations and manufactured using stereolithography. Bending experiments are performed up to the rupture point and main attributes representing the performance of the SL-based cellular wrenches are studied with respect to the generation parameters. The results show only slight difference between CAD (Computer-Aided Design) models of the design and the real printed parts. The number of seed points is found to control the main feature of the wrench performance whereas the relaxation time is found to have a secondary effect.
Efficacy and Safety of Topical Chloroquine in Mild to Moderate Dry Eye Disease

ABSTRACT Purpose: To evaluate the role of topical chloroquine (CHQ) as an adjunct to topical lubricants in the management of mild-moderate dry eye disease (DED) Methods: Prospective comparative pilot study allocated 150 patients with symptoms of mild to moderate DED to receive topical CMC 0.5% three times a day (group I, n = 75) or topical CHQ 0.03% twice a day with carboxymethylcellulose (CMC) 0.5% three times a day (group II, n = 75), for three months. Primary outcome measures were ocular surface disease index (OSDI) score and conjunctival impression cytology at 3 months. Secondary outcome measures were TBUT, Schirmer’s test, ocular surface staining and any adverse effects at 3 months. Follow up was performed at 1 and 3 months. Results: At three months, the OSDI score was significantly better in the CHQ group as compared with the CMC group (CMC-18.36 ± 4.03 (SD), CHQ group- 15.9 ± 5.18 (SD); p = . 002). Nelson’s score was 0.92 ± 0.69 (SD) in the CHQ group as compared with 1.60 ± 0.77 (SD) in the CMC group (p < .001). Abnormal impression cytology was observed in 20% cases in the CHQ group as compared with 61.3% cases in CMC group (p < .001). A significant correlation was observed between Nelson’s score and OSDI (Spearman’s rho correlation coefficient 0.414, p < .001). TBUT, Schirmer test and ocular surface staining were significantly better in the CHQ group (p < .001). No adverse effects were observed in any group. Conclusion: Topical chloroquine is a useful adjunct to topical lubricants in the management of DED as it decreases the underlying chronic inflammation and helps maintain ocular surface stability.
Effects of Gut Microbiota on the Bioavailability of Bioactive Compounds from Ginkgo Leaf Extracts

Ginkgo leaf extract (GLE) is a popular herbal medicine and dietary supplement for the treatment of various diseases, including cardiovascular disease. GLE contains a variety of secondary plant metabolites, such as flavonoids and terpenoids, as active components. Some of these phytochemicals have been known to be metabolized by gut microbial enzymes. The aim of this study was to investigate the effects of the gut microbiota on the pharmacokinetics of the main constituents of GLE using antibacterial-treated mice. The bilobalide, ginkgolide A, ginkgolide B, ginkgolide C, isorhamnetin, kaempferol, and quercetin pharmacokinetic profiles of orally administered GLE (600 mg/kg), with or without ciprofloxacin pretreatment (150 mg/kg/day for 3 days), were determined. In the antibacterial-treated mice, the maximum plasma concentration (Cmax) and area under the curve (AUC) of isorhamnetin were significantly (p < 0.05) increased when compared with the control group. The Cmax and AUC of kaempferol and quercetin (other flavonol glycosides) were slightly higher than those of the control group, but the difference was not statistically significant, while both parameters for terpenoids of GLE showed no significant difference between the antibacterial-treated and control groups. These results showed that antibacterial consumption may increase the bioavailability of isorhamnetin by suppressing gut microbial metabolic activities.
Guaranteed Synchronization Performance Control of Nonlinear Time-Delay MIMO Multiagent Systems With Actuator Faults

This paper addresses the synchronization control problem of leader–follower multiagent systems with each follower described by a class of high-order nonlinear multiple-input–multiple-output (MIMO) dynamics in the presence of time delays and actuator faults. A distributed synchronization scheme with guaranteed synchronization performance based on the radial basis function neural network (RBF NN) is introduced. We propose an augmented quadratic Lyapunov function by incorporating the lower bounds of control gain matrices and the actuator healthy indicator, and the problems caused by the unknown time-varying control gain matrices, actuator faults, and coupling terms among agents are solved. Meanwhile, the output of followers can track that of the leader and the steady state, and the transient performance of synchronization can be guaranteed, while all the other signals in the closed-loop system are guaranteed to be bounded. Finally, numerical analysis has been carried out to verify the effectiveness of the proposed controller.
Procalcitonin Clearance at 24, 48, 72, and 96 Hours and Mortality in Patients With Cancer and Sepsis: A Retrospective Cohort Study

Introduction: Previous studies have evaluated procalcitonin clearance (PCTc) as a marker of sepsis severity but at different time points and cutoffs. We aimed to assess the predictive performance of PCTc at different time points of sepsis management in patients with cancer. Methods: This retrospective cohort study included patients with cancer admitted to an intensive care unit between 2013 and 2016. We calculated PCTc at 24, 48, 72, and 96 hours after admission. Its predictive performance for hospital and 90-day mortality was analyzed with receiver operating characteristic curves and areas under the curves (AUCs). Sensitivity and specificity were calculated for different time points using different cutoffs. Results: We included 301 patients. Areas under the curves ranged from 0.62 for PCTc at 24 hours to 0.68 for PCTc at 72 and 96 hours for hospital mortality prediction, and from 0.61 for PCTc at 24 hours to 0.68 for PCTc at 72 hours for 90-day mortality prediction. For hospital mortality prediction, PCTc at 72 hours ≤80% showed the best sensitivity (96.0%; 95% confidence interval [CI]: 90.8%-98.7%), and PCTc at 96 hours ≤50% showed the best specificity (70.7%; 95% CI: 54.5%-83.9%). Conclusions: Procalcitonin clearance at 24, 48, 72, and 96 hours poorly predicted hospital and 90-day mortality. Therefore, daily PCT measurement should not be used to predict mortality for patients with cancer and sepsis.
Effects of ionizing radiation at Drosophila melanogaster with differently active hobo transposons

Abstract Purpose: The role of transposable elements in formation of radiobiological effects is understudied and contradictory. The aim of this study was to investigate the response of Drosophila melanogaster to irradiation depending on the level of activity hobo transposons and the role of hobo transposons in formation of ionizing radiation late effects. Materials and methods: The individuals of Drosophila melanogaster with different level activity of hobo-elements were exposed to acute irradiation in doses of 1–100 Gy at early ontogenesis stages. The reaction of individuals to exposure was studied using the larvae survival rate, morphological parameters of reproduction system, DNA damage rate, and mutability of mini-white locus. Results: We found the pronounced linear deferred effects of irradiation for animals with a high activity level of full-size hobo copies. The radiosensitivity of individuals with a mean level of activity transposon was whether higher or did not differ from the radiosensitivity of animals with a low activity hobo. Conclusion: The obtained results suggest that full-size hobo-elements with a high activity level (less often with a mean activity level) are responsible for delayed deleterious irradiation effects.
