Effectiveness of bedside Colonoscopies in Intensive Care Unit (CICU) might be limited by the poor quality of colonic preparation, and their feasibility. We sought to describe the indications and the profitability of CICU.

Retrospective, bicenter observational study (2004-2015) in unselected critically ill patients. We questioned the clinical profitability of CICU, according to its indications and preparation.

One hundred and eleven CICU were performed in 84 patients (sex ratio 1.4, 49M/35F; age 72.9years [61.7-84.7]), for lower gastro-intestinal bleeding in 67 patients (LGIB, 60.3%) and for other causes in 44 (39.6%). The profitability was more frequent when CICU was performed for another reason than LGIB (75% vs 28.3%; p<0.0001). Preparation was good in 47 procedures (42.3%) and allowed 33 complete CICU (29.7%). Fifty-six CICU (50.4%) were performed as a 2nd investigation after a contrast enhanced computed tomography. Three CICU were complicated by 3 hemodynamic and 2 respiratory failures, but none of them were fatal.

CICU is clinically useful in half of cases, in the diagnostic and the therapeutic management of critically ill patients. Its profitability is close to scheduled colonoscopies and superior in non-lower gastro-intestinal bleeding indications.

Mechanical ventilation (MV) is the cornerstone in the management of the acute respiratory distress syndrome (ARDS). Recent research suggests that decreasing the intensity of MV using lung protective ventilation (LPV) with lower tidal volume (Vt) and driving pressure (∆P) could improve survival. Extra-corporal CO
removal (ECCO
R) precisely enables LPV by allowing lower Vt, ∆P and mechanical power while maintaining PaCO
within a physiologic range. This study evaluates the potential cost-effectiveness of ECCO
R-enabled LPV in France.

We modelled the distribution over time of ventilated ARDS patients across 3 health-states (alive & ventilated, alive & weaned from ventilation, dead). We compared the outcomes of 3 strategies MV (no ECCO
R), LPV (ECCO
R when PaCO
>55mmHg) and Ultra-LPV (ECCO
R for all). Patients characteristics, ventilation settings, survival and lengths of stay were derived from a large ARDS epidemiology study. Survival benefits associated with lower ∆P were taken from the -enabled LPV strategies might provide cost-effective survival benefit. Additional data from interventional and observational studies are needed to support this preliminary model-based analysis.
The 2019 novel coronavirus disease pandemic (COVID-19) is one of the most serious health risks facing the global population. Teachers' responses are important in the management of the outbreak in schools. The purpose of this study is to examine teachers' risk perception, self-efficacy, response efficacy, and approach to disease prevention during the COVID-19 outbreak in Taiwan.

A descriptive, cross-sectional online survey was completed by 344 teachers across four levels of education. Pearson correlations between major variables were calculated. General linear model with a posthoc test was used to estimate the least squares means for each level of the independent variables and test the mean differences between the response scores.

The teachers with a higher risk perception showed a stronger adoption of disease prevention measures, but they also showed lower self-efficacy. In addition, teachers with higher self-efficacy had higher response efficiency. Female teachers had relatively stronger adoption of disease prevention measures than their male colleagues, and age was associated with a 0.040 point increase in adoption scores. Elementary school teachers were significantly stronger in this regard than teachers at junior high schools, high schools and universities in terms of behavior scores.

High implementation rate of Taiwanese teachers' disease prevention measures came from their higher risk perceptions. Among them, older female teachers, especially those who teach at elementary schools, are key to implementing disease prevention measures.

Then the pandemic experienced an explosive growth and quickly peaked. In order to respond to the challenge, the Chinese government quickly built hospitals, adjusted the diagnosis and treatment systems, deployed medical staff to support areas affected by the epidemic, isolated and treated infected patients as much as possible, reminded citizens to use good protection, and controlled the epidemic step-by-step. In this paper, we used official published data and medical literature about the transmission of COVID-19 as well as prevention and control guidelines issued by the Chinese government and hospitals, adopted a multi-dimensional analysis framework, divided the outbreak into three phases (1) "blind man touching the elephant" phase, (2) "opening Pandora's box" phase, (3) "whole offensive and whole defensive tactics" phase. This was done to describe the development of and response to the pandemic. This paper suggested that when dealing with similar outbreaks in the future, we should do a better job of providing protective guidance and material reserves in advance, strengthen the emergency response capacity of medical institutions, and aim to share this information with the public medical systems of other countries which also face severe tests.

The urine pregnancy test is one of the most useful methods for initially excluding pregnancy emergencies in the emergency department (ED). Although most urine pregnancy tests are regarded to be up to 99% accurate, false-negative results may lead ED physicians toward considering incorrect diagnoses, mask critical conditions, and even influence patient safety. Therefore, blood pregnancy tests (quantitative measurements) are clinically used for second-line screening. A double false-negative result from two pregnancy tests is very rare and has scarcely been reported for life-threatening ruptured ectopic pregnancy patients. In this report, for the first time, we describe a rare case of a 32-year-old female who suffered a life-threatening ruptured ectopic pregnancy and who had a double pregnancy test (both urine and blood) that was a false negative.
To carry out competency-based medical education, this study has established five Entrustable Professional Activities (EPAs) for the emergency medicine residents. The EPAs involve substantial data collection, which requires integration and analysis for the fi nal interpretation. Therefore, the "EPAs-Based e-Portfolio System" has been developed for assisting users to perform ad-hoc assessment, recording of a discussion, teaching, and feedback. The purpose of this study is to examine, from the perspective of the Technology Acceptance Model, residents and clinicians' experience of the EPAs-Based e-Portfolio System, including the use of functions such as recording, feedback, and assessment, as well as the impact thereof.

This study uses in-depth interviews as a means of data collection. The interviewees are from emergency medicine training hospitals in north, central, and south Taiwan-11 resident doctors and nine medical teachers.

The interviewees agree that (1) the EPAs-based e-Portfolio System provides usethey will be, which will then translate into greater willingness to use the system and higher frequency of actual use. The system can authentically reflect trainees' professional capabilities if the ad-hoc teaching and feedback in the clinical setting connect strongly with the online assessment and recording.
Computed tomography (CT) use in injured patients has continuously increased in the past decades. We designed and undertook this study to evaluate the frequency, and potential risks of incidental findings (IFs), and how they were processed in trauma patients receiving CT scans.

We retrospectively reviewed CT scans, official CT reports, and basic demographics in trauma patients who received CT scans at our emergency department in 2016. Scans with IFs prompted a detailed review of medical records to determine clinical significance and how they were processed. IFs were classified into three categories category I (potentially severe condition, in-time management required), category II (not urgent, follow-up needed), and category III (of minor concern). Multivariable logistic regression models were fitted to determine patient characteristics associated with IFs.

In the 4,092 scans enrolled, IFs were identified in 649 (15.9%). There were 13 (2.0%) category I, 306 (47.2%) category II, and 330 (50.8%) category III IFs. Patients with IFs were older than those without. No sex-based difference was found. Most (61.5%) of the scans were performed for the head; however, the abdomen had the highest IF prevalence (26.2%). Documentation about IFs was poor; 31% of category I, 91.9% of category II, and 97.0% of category III have no related record. Old age remains the risk predicting the presence of IFs, and every year of increasing age was independently associated with a higher prevalence of IFs (OR 1.019; 95% CI 1.015-1.024).

IFs are common in trauma CT scans; however, recognition and management remain poor. https://www.selleckchem.com/products/skf-34288-hydrochloride.html Abdomen and chest scans, and CT in older patients should remind us of increasing risks of IFs.

It is crucial to identify the pivotal factors for transferring patients with major trauma. We aim to delineate the clinical features and required aids of severe trauma patients and identify the differences between those who were admitted directly to a trauma center and those transferred from other hospitals.

We retrospectively reviewed all hospitalized trauma patients discharged from the ward in Chi-Mei Medical Center from January 1, 2017 to December 31, 2018. Of 5,846 patients, we identified 1,061 patients with Injury Severity Score >15, of which 92 patients were transferred from two branch hospitals (branch group), 172 patients were transferred from other hospitals (other group), and 797 patients were admitted directly through the emergency department (control group). We compared the clinical variables between control and the other two groups.

The branch group included a high proportion of pediatric patients (control 1.8%, other 2.3%, and branch 6.5%). The branch group demonstrated higher requiremeght play crucial roles in the management of transferred severe trauma patients.Since its description in 1985, the transapical petrosal transtentorial or Kawase approach has become a viable option of approaching lesions located in and around the apex of the petrous bone, Meckel's cave, and the anterolateral surface of the brain stem while preserving cranial nerve function. At the Brain Tumor Center, Erasmus MC, 25 patients were treated using the Kawase approach between 2004 and 2018 for various indications, including petroclival meningiomas, chondrosarcomas, pontine cavernomas, trigeminal schwannomas, and posterior circulation aneurysms. Hearing preservation was achieved in all patients; new abducens nerve and trochlear nerve palsies were present in three and six patients, respectively, of which a total of eight required ophthalmological correction. Seven patients experienced a cerebrospinal fluid fistula postoperatively, but this complication appeared self-limiting in all cases, with one patient experiencing secondary meningitis. After modifying our closure technique, the rate of fistulas dropped to zero.

The anti-spasticity efficacy of botulinum toxin (BoNT) injection has been well established for patients with chronic stroke; however, extracorporeal shock wave therapy (ESWT), i.e. focused shockwave (FSW) and radial shockwave (RSW), has recently been applied. We aimed to investigate the comparative effectiveness of BoNT vs. ESWT in the reduction of spasticity among stroke survivors.

PubMed, EMBASE, MEDLINE and Cochrane CENTRAL were searched from the earliest record to September 2021 for randomized controlled trials. Weighted mean differences (WMDs) on the reduction of the Modified Ashworth Scale before or at the 6th post-treatment week (short-term) and between the 7th and 12th weeks (mid-term) after the intervention were calculated. Ranking probabilities of the WMD were simulated to determine which treatment had the potential to possess the best effectiveness. inplasy.com registration INPLASY202170018.

A total of 33 studies comprising 1,930 patients were enrolled. The network meta-analysis revealed thatded to validate the role of ESWT in reducing post-stroke spasticity.

The high recurrence rate after radical resection of pancreatic ductal adenocarcinoma (PDAC) leads to its poor prognosis. We aimed to develop a model to preoperatively predict the risk of recurrence based on computed tomography (CT) radiomics and multiple clinical parameters.

Datasets were retrospectively collected and analysed of 220 PDAC patients who underwent contrast-enhanced computed tomography (CE-CT) and received radical resection at 3 institutions in China between 2013 and 2017, with 153 from one institution as a training set, the remaining 67 as a validation set. For each patient, CT radiomics features were extracted from intratumoral and peritumoral regions to establish intratumoral, peritumoral and combined radiomics models using artificial neural network (ANN) algorithm. By incorporating clinical factors, radiomics-clinical nomograms were finally built by multivariable logistic regression analysis to predict 1- and 2-year recurrence risk.

However, neurological manifestations are very common. Among these, ischemic stroke or cerebral hemorrhage may have unfavorable outcome. The mechanisms leading to cerebral damage by SARS-CoV2 are still under debate. One of the most accepted theories implies an endothelial activation which in turns increase the risk of thrombus formation with the development of stroke, either ischemic or hemorrhagic. The more severe the COVID-19 disease, the higher the risk of stroke. Stroke in ICU patients are not frequent, but cerebral hemorrhage has devastating effects with high mortality. In these pictorial essay of case reports, main clinical aspects are discussed, along with a summary of the evidence about pathophysiology and treatment of these patients.RNAs adopt various conformations to perform different functions in cells. Incapable of acquiring intermediates, the key initiations of ligand recognition in the adenine riboswitch have not been characterized. In this work, stopped-flow fluorescence was used to track structural switches in the full-length adenine riboswitch in real time. We used PLOR (position-selective labeling of RNA) to incorporate fluorophores into desired positions in the RNA. The switching sequence P1 responded to adenine more rapidly than helix P4 and the binding pocket, followed by stabilization of the binding pocket, P4, and annealing of P1. Moreover, a transient intermediate consisting of an unwound P1 was detected during adenine binding. These events were observed in both the WT riboswitch and a functional mutant. The findings provide insight into the conformational changes of the riboswitch RNA triggered by a ligand.Electric vehicles (EVs) are currently being promoted to reduce transport emissions. We present a life cycle assessment of EV charging behaviors based on marginal emissions factors. For Great Britain, we find that electricity consumption accounts for the highest proportion of life cycle carbon emissions from EVs. We highlight the potential life cycle carbon emissions reduction brought by charging during periods when the grid mix produces relatively low emissions. While our study focuses on Great Britain, we have applied our methodology to several European countries with contrasting electricity generation mixes. Our analysis demonstrates that countries with a high proportion of fossil energy will have reduced benefits from deploying EVs, but are likely to achieve increased benefits from smart charging approaches. We conclude that using marginal emissions factors is essential to understanding the greenhouse gas impacts of EV deployment, and that smart charging tied to instantaneous grid emissions factors can bring benefits.We produced oils via hydrothermal liquefaction (HTL) of binary mixtures of biomass components (e.g., lignin, cellulose, starch) with different plastics and binary mixtures of plastics themselves. Cellulose, starch, and lignin demonstrated synergistic interactions (i.e., enhanced oil yields) with the plastics tested (polypropylene, polycarbonate, polystyrene, and polyethylene terephthalate). Polystyrene exhibited synergy during HTL with the three other plastics as did polypropylene during HTL with PET or PC. We used the experimental results to develop the first component-additivity model that predicts the oil yields from HTL of biomass-plastic and plastic-plastic mixtures. The model accounts for interactions among and between biomass components and plastic components in sub-, near-, and supercritical water. The model predicts 88% of 48 published oil yields from HTL experiments with mixtures containing plastics to within 10 wt%.Clustering of magnetic nanoparticles can dramatically change their collective magnetic properties, and it consequently may influence their performance in biomedical and technological applications. Owing to tailored surface modification of magnetic particles such composites represent stable systems. Here, we report ferronematic mixtures that contain anisotropic clusters of mesogen-hybridized cobalt ferrite nanoparticles dispersed in liquid crystal host studied by different experimental methods-magnetization measurements, small-angle X-ray scattering (SAXS), small-angle neutron scattering (SANS), and capacitance measurements. These measurements reveal non-monotonic dependencies of magnetization curves and the Fréedericksz transition on the magnetic nanoparticles concentration. This can be explained by the formation of clusters, whose structures were determined by SAXS measurements. Complementary to the magnetization measurements, SANS measurements of the samples were performed for different magnetic field strengths to obtain information on the orientation of the liquid crystal molecules. We demonstrated that such hybrid materials offer new avenues for tunable materials.Two-dimensional (2D) organic-inorganic halide perovskites (OIHPs) with an alternating stacked structure of an organic layer and an inorganic layer draw significant attention for photovoltaics, multiple quantum-well, and passivation of three-dimensional perovskites. Although the low-cost and simple spin-coating process of these materials offers a vast platform to study fundamental properties and help them achieve rapid progress in electronics and optoelectronics, chemical vapor deposition (CVD) growth is also necessary for large-area, epitaxial, selective, and conformal growth. Here, one-step CVD strategies for 2D OIHP growth are proposed, and the growth trends depending on the precursor and substrate conditions are discussed. We report a CVD-grown nontoxic, lead-free 2D tin-OIHP flake to show the system offering a universal route to synthesize perovskite crystals based on arbitrary organic and inorganic components.Terahertz (THz) frequency occupies a large portion of the electromagnetic spectrum that is between the infrared and microwave regions. Recent advances in THz application have stimulated interests regarding the biological effects within this frequency range. In the current study, we report that irradiation with a single-frequency THz laser on mice cortical neuron cultures increases excitatory synaptic transmission and neuronal firing activities. Microarray assay reveals gene expression dynamics after THz exposure, which is consistent with morphology and electrophysiology results. Besides, certain schedule of THz irradiation inhibits the proliferation of oligodendrocyte precursor cells (OPCs) and promotes OPC differentiation. Of note, the myelination process is enhanced after THz exposure. In summary, our observations suggest that THz irradiation can modulate the functions of different neuronal cells, with different sensitivity to THz. https://www.selleckchem.com/products/sodium-oxamate.html These results provide important understanding of the mechanisms that govern THz interactions with nervous systems and suggest THz wave as a new strategy for neuromodulation.Cells maintain their volume through fine intracellular osmolarity regulation. Osmotic challenges drive fluid into or out of cells causing swelling or shrinkage, respectively. The dynamics of cell volume changes depending on the rheology of the cellular constituents and on how fast the fluid permeates through the membrane and cytoplasm. We investigated whether and how poroelasticity can describe volume dynamics in response to osmotic shocks. We exposed cells to osmotic perturbations and used defocusing epifluorescence microscopy on membrane-attached fluorescent nanospheres to track volume dynamics with high spatiotemporal resolution. We found that a poroelastic model that considers both geometrical and pressurization rates captures fluid-cytoskeleton interactions, which are rate-limiting factors in controlling volume changes at short timescales. Linking cellular responses to osmotic shocks and cell mechanics through poroelasticity can predict the cell state in health, disease, or in response to novel therapeutics.The gut microbiota plays a crucial role in maintaining health. Monitoring the complex dynamics of its microbial population is, therefore, important. Here, we present a deep convolution network that can characterize the dynamic changes in the gut microbiota using low-resolution images of fecal samples. Further, we demonstrate that the microbial relative abundances, quantified via 16S rRNA amplicon sequencing, can be quantitatively predicted by the neural network. Our approach provides a simple and inexpensive method of gut microbiota analysis.

AI is in the headlines every day, with the latest news highlighting companies like Nvidia, Apple, Alphabet, Meta, Taiwan Semiconductor, and others leading the charge. Today, nearly everyone has interacted with AI in some capacity. It may have helped you write a paper, craft a letter, or compose a thank you note. Lecturer Sean O’Brien, a cybersecurity expert, explains what artificial intelligence is, its intended purposes, and how it will transform our lives.

International affairs are at the top of the news all around the world. With hot conflicts in Ukraine, Gaza, and the Sahel, and would-be confrontations in the Taiwan Strait, the Red Sea, and elsewhere, there is a lot of reporting about various visits of the US secretaries of state and defense and of sensitive negotiations with this country or that. But what is the role of the CIA in all this? Is that role different now that the CIA is led by a professional diplomat? And how different is it now that the CIA is less an intelligence collection agency and more a para-military body? On this episode of the Whistleblowers, John Kiriakou speaks with whistleblower and former senior CIA officer Mel Goodman to answer all these questions.

When people think about mass destruction in war they typically think about chemical, biological, or nuclear weapons. But there is something that could easily have a similar body count with potentially longer lasting results. A cyber attack could shut down our infrastructure, prevent basic services and cripple our just in time food and grocery system. In many respects a serious cyber attack would be similar to a an EMP attack or a solar flair. It would cut us off from the luxuries, resources, and support we have become accustomed to. If you have ever heard a prepper talk about the results of an electromagnetic pulse then this video will sound familiar to you.

Retrospective, bicenter observational study (2004-2015) in unselected critically ill patients. We questioned the clinical profitability of CICU, according to its indications and preparation.

One hundred and eleven CICU were performed in 84 patients (sex ratio 1.4, 49M/35F; age 72.9years [61.7-84.7]), for lower gastro-intestinal bleeding in 67 patients (LGIB, 60.3%) and for other causes in 44 (39.6%). The profitability was more frequent when CICU was performed for another reason than LGIB (75% vs 28.3%; p<0.0001). Preparation was good in 47 procedures (42.3%) and allowed 33 complete CICU (29.7%). Fifty-six CICU (50.4%) were performed as a 2nd investigation after a contrast enhanced computed tomography. Three CICU were complicated by 3 hemodynamic and 2 respiratory failures, but none of them were fatal.

CICU is clinically useful in half of cases, in the diagnostic and the therapeutic management of critically ill patients. Its profitability is close to scheduled colonoscopies and superior in non-lower gastro-intestinal bleeding indications.

Teachers' responses are important in the management of the outbreak in schools. The purpose of this study is to examine teachers' risk perception, self-efficacy, response efficacy, and approach to disease prevention during the COVID-19 outbreak in Taiwan.

The urine pregnancy test is one of the most useful methods for initially excluding pregnancy emergencies in the emergency department (ED). Although most urine pregnancy tests are regarded to be up to 99% accurate, false-negative results may lead ED physicians toward considering incorrect diagnoses, mask critical conditions, and even influence patient safety. Therefore, blood pregnancy tests (quantitative measurements) are clinically used for second-line screening. A double false-negative result from two pregnancy tests is very rare and has scarcely been reported for life-threatening ruptured ectopic pregnancy patients. In this report, for the first time, we describe a rare case of a 32-year-old female who suffered a life-threatening ruptured ectopic pregnancy and who had a double pregnancy test (both urine and blood) that was a false negative.
To carry out competency-based medical education, this study has established five Entrustable Professional Activities (EPAs) for the emergency medicine residents. The EPAs involve substantial data collection, which requires integration and analysis for the fi nal interpretation. Therefore, the "EPAs-Based e-Portfolio System" has been developed for assisting users to perform ad-hoc assessment, recording of a discussion, teaching, and feedback. The purpose of this study is to examine, from the perspective of the Technology Acceptance Model, residents and clinicians' experience of the EPAs-Based e-Portfolio System, including the use of functions such as recording, feedback, and assessment, as well as the impact thereof.

This study uses in-depth interviews as a means of data collection. The interviewees are from emergency medicine training hospitals in north, central, and south Taiwan-11 resident doctors and nine medical teachers.

The interviewees agree that (1) the EPAs-based e-Portfolio System provides usethey will be, which will then translate into greater willingness to use the system and higher frequency of actual use. The system can authentically reflect trainees' professional capabilities if the ad-hoc teaching and feedback in the clinical setting connect strongly with the online assessment and recording.
Computed tomography (CT) use in injured patients has continuously increased in the past decades. We designed and undertook this study to evaluate the frequency, and potential risks of incidental findings (IFs), and how they were processed in trauma patients receiving CT scans.

We retrospectively reviewed CT scans, official CT reports, and basic demographics in trauma patients who received CT scans at our emergency department in 2016. Scans with IFs prompted a detailed review of medical records to determine clinical significance and how they were processed. IFs were classified into three categories category I (potentially severe condition, in-time management required), category II (not urgent, follow-up needed), and category III (of minor concern). Multivariable logistic regression models were fitted to determine patient characteristics associated with IFs.

In the 4,092 scans enrolled, IFs were identified in 649 (15.9%). There were 13 (2.0%) category I, 306 (47.2%) category II, and 330 (50.8%) category III IFs. Patients with IFs were older than those without. No sex-based difference was found. Most (61.5%) of the scans were performed for the head; however, the abdomen had the highest IF prevalence (26.2%). Documentation about IFs was poor; 31% of category I, 91.9% of category II, and 97.0% of category III have no related record. Old age remains the risk predicting the presence of IFs, and every year of increasing age was independently associated with a higher prevalence of IFs (OR 1.019; 95% CI 1.015-1.024).

IFs are common in trauma CT scans; however, recognition and management remain poor. https://www.selleckchem.com/products/skf-34288-hydrochloride.html Abdomen and chest scans, and CT in older patients should remind us of increasing risks of IFs.

It is crucial to identify the pivotal factors for transferring patients with major trauma. We aim to delineate the clinical features and required aids of severe trauma patients and identify the differences between those who were admitted directly to a trauma center and those transferred from other hospitals.

We retrospectively reviewed all hospitalized trauma patients discharged from the ward in Chi-Mei Medical Center from January 1, 2017 to December 31, 2018. Of 5,846 patients, we identified 1,061 patients with Injury Severity Score >15, of which 92 patients were transferred from two branch hospitals (branch group), 172 patients were transferred from other hospitals (other group), and 797 patients were admitted directly through the emergency department (control group). We compared the clinical variables between control and the other two groups.

The branch group included a high proportion of pediatric patients (control 1.8%, other 2.3%, and branch 6.5%). The branch group demonstrated higher requiremeght play crucial roles in the management of transferred severe trauma patients.Since its description in 1985, the transapical petrosal transtentorial or Kawase approach has become a viable option of approaching lesions located in and around the apex of the petrous bone, Meckel's cave, and the anterolateral surface of the brain stem while preserving cranial nerve function. At the Brain Tumor Center, Erasmus MC, 25 patients were treated using the Kawase approach between 2004 and 2018 for various indications, including petroclival meningiomas, chondrosarcomas, pontine cavernomas, trigeminal schwannomas, and posterior circulation aneurysms. Hearing preservation was achieved in all patients; new abducens nerve and trochlear nerve palsies were present in three and six patients, respectively, of which a total of eight required ophthalmological correction. Seven patients experienced a cerebrospinal fluid fistula postoperatively, but this complication appeared self-limiting in all cases, with one patient experiencing secondary meningitis. After modifying our closure technique, the rate of fistulas dropped to zero.

The anti-spasticity efficacy of botulinum toxin (BoNT) injection has been well established for patients with chronic stroke; however, extracorporeal shock wave therapy (ESWT), i.e. focused shockwave (FSW) and radial shockwave (RSW), has recently been applied. We aimed to investigate the comparative effectiveness of BoNT vs. ESWT in the reduction of spasticity among stroke survivors.

PubMed, EMBASE, MEDLINE and Cochrane CENTRAL were searched from the earliest record to September 2021 for randomized controlled trials. Weighted mean differences (WMDs) on the reduction of the Modified Ashworth Scale before or at the 6th post-treatment week (short-term) and between the 7th and 12th weeks (mid-term) after the intervention were calculated. Ranking probabilities of the WMD were simulated to determine which treatment had the potential to possess the best effectiveness. inplasy.com registration INPLASY202170018.

A total of 33 studies comprising 1,930 patients were enrolled. The network meta-analysis revealed thatded to validate the role of ESWT in reducing post-stroke spasticity.

The high recurrence rate after radical resection of pancreatic ductal adenocarcinoma (PDAC) leads to its poor prognosis. We aimed to develop a model to preoperatively predict the risk of recurrence based on computed tomography (CT) radiomics and multiple clinical parameters.

Datasets were retrospectively collected and analysed of 220 PDAC patients who underwent contrast-enhanced computed tomography (CE-CT) and received radical resection at 3 institutions in China between 2013 and 2017, with 153 from one institution as a training set, the remaining 67 as a validation set. For each patient, CT radiomics features were extracted from intratumoral and peritumoral regions to establish intratumoral, peritumoral and combined radiomics models using artificial neural network (ANN) algorithm. By incorporating clinical factors, radiomics-clinical nomograms were finally built by multivariable logistic regression analysis to predict 1- and 2-year recurrence risk.

However, neurological manifestations are very common. Among these, ischemic stroke or cerebral hemorrhage may have unfavorable outcome. The mechanisms leading to cerebral damage by SARS-CoV2 are still under debate. One of the most accepted theories implies an endothelial activation which in turns increase the risk of thrombus formation with the development of stroke, either ischemic or hemorrhagic. The more severe the COVID-19 disease, the higher the risk of stroke. Stroke in ICU patients are not frequent, but cerebral hemorrhage has devastating effects with high mortality. In these pictorial essay of case reports, main clinical aspects are discussed, along with a summary of the evidence about pathophysiology and treatment of these patients.RNAs adopt various conformations to perform different functions in cells. Incapable of acquiring intermediates, the key initiations of ligand recognition in the adenine riboswitch have not been characterized. In this work, stopped-flow fluorescence was used to track structural switches in the full-length adenine riboswitch in real time. We used PLOR (position-selective labeling of RNA) to incorporate fluorophores into desired positions in the RNA. The switching sequence P1 responded to adenine more rapidly than helix P4 and the binding pocket, followed by stabilization of the binding pocket, P4, and annealing of P1. Moreover, a transient intermediate consisting of an unwound P1 was detected during adenine binding. These events were observed in both the WT riboswitch and a functional mutant. The findings provide insight into the conformational changes of the riboswitch RNA triggered by a ligand.Electric vehicles (EVs) are currently being promoted to reduce transport emissions. We present a life cycle assessment of EV charging behaviors based on marginal emissions factors. For Great Britain, we find that electricity consumption accounts for the highest proportion of life cycle carbon emissions from EVs. We highlight the potential life cycle carbon emissions reduction brought by charging during periods when the grid mix produces relatively low emissions. While our study focuses on Great Britain, we have applied our methodology to several European countries with contrasting electricity generation mixes. Our analysis demonstrates that countries with a high proportion of fossil energy will have reduced benefits from deploying EVs, but are likely to achieve increased benefits from smart charging approaches. We conclude that using marginal emissions factors is essential to understanding the greenhouse gas impacts of EV deployment, and that smart charging tied to instantaneous grid emissions factors can bring benefits.We produced oils via hydrothermal liquefaction (HTL) of binary mixtures of biomass components (e.g., lignin, cellulose, starch) with different plastics and binary mixtures of plastics themselves. Cellulose, starch, and lignin demonstrated synergistic interactions (i.e., enhanced oil yields) with the plastics tested (polypropylene, polycarbonate, polystyrene, and polyethylene terephthalate). Polystyrene exhibited synergy during HTL with the three other plastics as did polypropylene during HTL with PET or PC. We used the experimental results to develop the first component-additivity model that predicts the oil yields from HTL of biomass-plastic and plastic-plastic mixtures. The model accounts for interactions among and between biomass components and plastic components in sub-, near-, and supercritical water. The model predicts 88% of 48 published oil yields from HTL experiments with mixtures containing plastics to within 10 wt%.Clustering of magnetic nanoparticles can dramatically change their collective magnetic properties, and it consequently may influence their performance in biomedical and technological applications. Owing to tailored surface modification of magnetic particles such composites represent stable systems. Here, we report ferronematic mixtures that contain anisotropic clusters of mesogen-hybridized cobalt ferrite nanoparticles dispersed in liquid crystal host studied by different experimental methods-magnetization measurements, small-angle X-ray scattering (SAXS), small-angle neutron scattering (SANS), and capacitance measurements. These measurements reveal non-monotonic dependencies of magnetization curves and the Fréedericksz transition on the magnetic nanoparticles concentration. This can be explained by the formation of clusters, whose structures were determined by SAXS measurements. Complementary to the magnetization measurements, SANS measurements of the samples were performed for different magnetic field strengths to obtain information on the orientation of the liquid crystal molecules. We demonstrated that such hybrid materials offer new avenues for tunable materials.Two-dimensional (2D) organic-inorganic halide perovskites (OIHPs) with an alternating stacked structure of an organic layer and an inorganic layer draw significant attention for photovoltaics, multiple quantum-well, and passivation of three-dimensional perovskites. Although the low-cost and simple spin-coating process of these materials offers a vast platform to study fundamental properties and help them achieve rapid progress in electronics and optoelectronics, chemical vapor deposition (CVD) growth is also necessary for large-area, epitaxial, selective, and conformal growth. Here, one-step CVD strategies for 2D OIHP growth are proposed, and the growth trends depending on the precursor and substrate conditions are discussed. We report a CVD-grown nontoxic, lead-free 2D tin-OIHP flake to show the system offering a universal route to synthesize perovskite crystals based on arbitrary organic and inorganic components.Terahertz (THz) frequency occupies a large portion of the electromagnetic spectrum that is between the infrared and microwave regions. Recent advances in THz application have stimulated interests regarding the biological effects within this frequency range. In the current study, we report that irradiation with a single-frequency THz laser on mice cortical neuron cultures increases excitatory synaptic transmission and neuronal firing activities. Microarray assay reveals gene expression dynamics after THz exposure, which is consistent with morphology and electrophysiology results. Besides, certain schedule of THz irradiation inhibits the proliferation of oligodendrocyte precursor cells (OPCs) and promotes OPC differentiation. Of note, the myelination process is enhanced after THz exposure. In summary, our observations suggest that THz irradiation can modulate the functions of different neuronal cells, with different sensitivity to THz. https://www.selleckchem.com/products/sodium-oxamate.html These results provide important understanding of the mechanisms that govern THz interactions with nervous systems and suggest THz wave as a new strategy for neuromodulation.Cells maintain their volume through fine intracellular osmolarity regulation. Osmotic challenges drive fluid into or out of cells causing swelling or shrinkage, respectively. The dynamics of cell volume changes depending on the rheology of the cellular constituents and on how fast the fluid permeates through the membrane and cytoplasm. We investigated whether and how poroelasticity can describe volume dynamics in response to osmotic shocks. We exposed cells to osmotic perturbations and used defocusing epifluorescence microscopy on membrane-attached fluorescent nanospheres to track volume dynamics with high spatiotemporal resolution. We found that a poroelastic model that considers both geometrical and pressurization rates captures fluid-cytoskeleton interactions, which are rate-limiting factors in controlling volume changes at short timescales. Linking cellular responses to osmotic shocks and cell mechanics through poroelasticity can predict the cell state in health, disease, or in response to novel therapeutics.The gut microbiota plays a crucial role in maintaining health. Monitoring the complex dynamics of its microbial population is, therefore, important. Here, we present a deep convolution network that can characterize the dynamic changes in the gut microbiota using low-resolution images of fecal samples. Further, we demonstrate that the microbial relative abundances, quantified via 16S rRNA amplicon sequencing, can be quantitatively predicted by the neural network. Our approach provides a simple and inexpensive method of gut microbiota analysis.

The interactive effect is significant in the Chinese stock market, exacerbating the abnormal market volatilities and risk contagion. Based on daily stock returns in the Shanghai Stock Exchange (SSE) A-shares, this paper divides the period between 2005 and 2018 into eight bull and bear market stages to investigate interactive patterns in the Chinese financial market. We employ the Least Absolute Shrinkage and Selection Operator (LASSO) method to construct the stock network, compare the heterogeneity of bull and bear markets, and further use the Map Equation method to analyse the evolution of modules in the SSE A-shares market. Empirical results show that (1) the connected effect is more significant in bear markets than bull markets and gives rise to abnormal volatilities in the stock market; (2) a system module can be found in the network during the first four stages, and the industry aggregation effect leads to module differentiation in the last four stages; (3) some stocks have leading effects on others throughout eight periods, and medium- and small-cap stocks with poor financial conditions are more likely to become risk sources, especially in bear markets. Our conclusions are beneficial to improving investment strategies and making regulatory policies.As a major threat factor for female health, breast cancer (BC) has garnered a lot of attention for its malignancy and diverse molecules participating in its carcinogenesis process. Among these complex carcinogenesis processes, cell proliferation, epithelial-to-mesenchymal transition (EMT), mesenchymal-to-epithelial transition (MET), and angiogenesis are the major causes for the occurrence of metastasis and chemoresistance which account for cancer malignancy. MicroRNAs packaged and secreted in exosomes are termed "exosomal microRNAs (miRNAs)". Nowadays, more researches have uncovered the roles of exosomal miRNAs played in BC metastasis. In this review, we recapitulated the dual actions of exosomal miRNAs exerted in the aggressiveness of BC by influencing migration, invasion, and distant metastasis. Next, we presented how exosomal miRNAs modify angiogenesis and stemness maintenance. Clinically, several exosomal miRNAs can govern the transformation between drug sensitivity and chemoresistance. Since the balance of the number and type of exosomal miRNAs is disturbed in pathological conditions, they are able to serve as instructive biomarkers for BC diagnosis and prognosis. More efforts are needed to connect the theoretical studies and clinical traits together. https://www.selleckchem.com/products/5-chloro-2-deoxyuridine.html This review provides an outline of the pleiotropic impacts of exosomal miRNAs on BC metastasis and their clinical implications, paving the way for future personalized drugs.
Intensive care unit (ICU) admission following a short-term emergency department (ED) revisit has been considered a particularly undesirable outcome among return-visit patients, although their in-hospital prognosis has not been discussed. We aimed to compare clinical outcomes between adult patients admitted to the ICU after unscheduled ED revisits and those admitted during index ED visits.

This retrospective study was conducted at two tertiary medical centers in Taiwan from 1 January 2016 to 31 December 2017. All adult non-trauma patients admitted to the ICU directly via the ED during the study period were included and divided into two comparison groups patients admitted to the ICU during index ED visits and those admitted to the ICU during return ED visits. The outcomes of interest included in-hospital mortality, mechanical ventilation (MV) support, profound shock, hospital length of stay (HLOS), and total medical cost.

Altogether, 12,075 patients with a mean (standard deviation) age of 64.6 (15.7) yearot indicate poor prognosis in ED practice.
ICU admission following a return ED visit was not associated with major in-hospital outcomes including mortality, MV support, shock, increased HLOS, or medical cost. Although ICU admissions following ED revisits are considered serious adverse events, they may not indicate poor prognosis in ED practice.Electrochemical biosensors are an increasingly attractive option for the development of a novel analyte detection method, especially when integration within a point-of-use device is the overall objective. In this context, accuracy and sensitivity are not compromised when working with opaque samples as the electrical readout signal can be directly read by a device without the need for any signal transduction. However, electrochemical detection can be susceptible to substantial signal drift and increased signal error. This is most apparent when analysing complex mixtures and when using small, single-use, screen-printed electrodes. Over recent years, analytical scientists have taken inspiration from self-referencing ratiometric fluorescence methods to counteract these problems and have begun to develop ratiometric electrochemical protocols to improve sensor accuracy and reliability. This review will provide coverage of key developments in ratiometric electrochemical (bio)sensors, highlighting innovative assay design, and the experiments performed that challenge assay robustness and reliability.Ovarian clear cell carcinoma (OCCC) is a histological subtype of ovarian cancer that is more frequent in Asian countries (~25% of ovarian cancers) than in US/European countries (less than 10%). OCCC is refractory to conventional platinum-based chemotherapy, which is effective against high-grade serous carcinoma (HGSC), a major histological subtype of ovarian cancer. Notably, deleterious mutations in SWI/SNF chromatin remodeling genes, such as ARID1A, are common in OCCC but rare in HGSC. Because this complex regulates multiple cellular processes, including transcription and DNA repair, molecularly targeted therapies that exploit the consequences of SWI/SNF deficiency may have clinical efficacy against OCCC. Three such strategies have been proposed to date prioritizing a gemcitabine-based chemotherapeutic regimen, synthetic lethal therapy targeting vulnerabilities conferred by SWI/SNF deficiency, and immune checkpoint blockade therapy that exploits the high mutational burden of ARID1A-deficient tumor. Thus, ARID1A deficiency has potential as a biomarker for precision medicine of ovarian cancer.

Central nervous system (CNS) metastasis from nasopharyngeal carcinoma (NPC) is rare and presents with high morbidity and mortality. As a rare entity, a few patients with CNS metastasis from NPC have been reported, and no studies were available on treatment and prognosis. Based on our clinical experience, early diagnosis with incorporation of a clear palliative plan is imperative in providing holistic care for patients with locally-invasive and metastatic nasopharyngeal carcinoma.

Our study reports a case of a 48-year-old Filipino male with known NPC Stage IVB who developed acute symptoms of constipation, urinary retention, and bilateral lower limb weakness and numbness. Magnetic resonance imaging showed intramedullary lesions in multiple segments of the spinal cord. Steroid and radiotherapy of the spine were initiated with noted transient improvement of the motor strength. Subsequently, he developed cancer-related stroke. The patient progressively deteriorated despite best medical care.

In the present study, we sought to screen all prior diseases associated with PC incidence concurrently and construct pathways for the diseases. Materials and methods This total population-based case-control study used data collected from Taiwan's National Health Insurance Research Database for the period covering 1997-2013. The case group included 3726 patients newly diagnosed with PC, who were precisely matched to 3726 controls based on gender, age, residence, and insurance premiums. Stepwise multivariate logistic regression was used to screen previous diseases in windows of 1, 2 …, 9 years prior to the first diagnosis of PC. Path analysis was used to construct the pathways between relevant prior diseases and PC. Results Within 1 year prior to PC diagnosis, a total of 11 diseases were significantly correlated with PC, included 9 positive and 2 negative associations. Path analysis identified diabetes, pancreatitis as diseases with direct positive pathways to PC incidence, and dementia with direct negative pathways. Conclusions It appears that diabetes, peptic ulcer, and digestive conditions were the prior diseases associated with PC incidence.
Modifications to implant surface properties, including topography, chemistry, and wettability, alter immune response, osteoblast differentiation of bone marrow stromal cells (MSCs), and implant integration in vivo. Dielectric barrier discharge (DBD) plasma treatment has been used to sterilize surfaces and remove adsorbed carbon, improving wettability. However, unless it is used immediately prior to placement, ambient atmospheric hydrocarbons rapidly adhere to the surface, thereby reducing its hydrophilicity. Moreover, this method is not practical in many clinical settings. The aim of this study was to evaluate the effectiveness of an on-site benchtop modification technique for implants at time of placement, consisting of a DBD plasma that is used to sterilize implants that are pre-packaged in a vacuum. Effects of the plasma-treatment on implant surface properties and cellular response of MSCs and osteoblasts were assessed in vitro.

Titanium-aluminum-vanadium implant surfaces were grit-blasted (GB) or gritdifferentiation and activity of MSCs and osteoblasts that are in contact with these implant surfaces.
Overall, these data suggest that application of benchtop plasma at the time of implant placement can alter the surface free energy of an implant surface without modifying surface chemical composition and enhance the differentiation and activity of MSCs and osteoblasts that are in contact with these implant surfaces.
Here we used 3D finite element analysis (FEA) to analyze and directly compare stress distribution and crack propagation in identical cracked tooth models after treatment with various materials and designs.

A 3D model of a cracked tooth was generated. We then applied eight restoration models, comprising combinations of three kinds of restoration designs (inlay, onlay, and crown) and four types of restoration materials (direct composite resin, indirect composite resin, ceramic, and gold). A 1000-N occlusal load was applied on the three reference points of the ball-shaped part in the direction of the longitudinal axis, causing crack line separation in the buccolingual direction. https://www.selleckchem.com/products/BIBR1532.html Stress distribution was analyzed on the occlusal surface, bottom level of the restoration, and mesiodistal longitudinal section. The stress on the lower margin of the crack surface was measured at 15 points on each model.

Ceramic inlay and onlay showed stress concentration at the restoration bottom, and low stress on the lower margin of the crack surface. Direct and indirect resin restorations exhibited low stress on the restoration bottom, and high stress on the proximal end of the lower margin of the crack surface. With a resin-unfilled gold crown, stress was concentrated on the crown bottom and the lower margin of the crack surface. Direct resin filling inside the gold crown yielded significantly decreased stress on both areas.

Our results suggest that inlay and onlay ceramic restorations, and gold crown with resin filling inside, are advantageous methods for preventing further crack propagation.
