Soil bacteria are decomposer organisms crucial for the biodegradation of organic pollutants, mineralization of dead organic matter and the turnover of biogenic elements. In their environment they are constantly exposed to membrane-lytic enzymes emitted to the soil by other microorganisms competing for the same niche. Therefore, the composition and structure of their membranes is of utmost importance for survival in the harsh environment. Although soil bacteria species can be Gram-negative or Gram-positive and their membranes differ significantly, they are formed by phospholipids belonging mainly to three classes phosphatidylethanolamines (PE), phosphatidylglycerols (PG) and cardiolipins (CL). The correlation of the membrane phospholipid composition and its susceptibility to secretory membrane-lytic enzymes is widely unknown; thus, to shed light on these phenomena we applied the Langmuir monolayer technique to construct models of soil bacteria membranes differing in the mutual proportion of the main phospholipids. To characterize the systems we studied their elasticity, mesoscopic texture, 2D crystalline structure and discussed the thermodynamics of the interactions between their components. The model membranes were exposed to secretory phospholipase A2. It turned out that in spite of the structural similarities the model membranes differed significantly in their susceptibility to s-PLA2 attack. https://www.selleckchem.com/products/ms-275.html The membranes devoid of cardiolipin were completely degraded, whereas, these containing cardiolipin were much more resistant to the enzymatic hydrolysis. It also turned out that the sole presence of cardiolipin in the model membrane did not guarantee the membrane durability and that the interplay between cardiolipin and the zwitterionic phosphatidylethanolamine was here of crucial importance. Aging of red blood cells (RBCs) is associated with alteration in a wide range of RBC features, occurring each on its own timescale. A number of these changes are interrelated and initiate a cascade of biochemical and structural transformations, including band-3 clustering and phosphatidylserine (PS) externalization. Using specific band-3 clustering agents (acridine orange (AO) and ZnCl2), we examined whether treatment of RBCs with these agents may affects PS externalization and whether this process is Ca2+-dependent. RBCs were isolated from the blood of eight healthy donors upon obtaining their informed consent. The suspension was supplemented with increasing concentrations of AO or ZnCl2 (from 0.5 to 2.0 mM) and incubated at 25 °C for 60 min. To detect PS at the RBC surface, we used allophycocyanin-conjugated recombinant human Annexin V. We demonstrated, that treatment of RBCs with both clustering agents caused an elevation in the percent of cells positively labeled by Annexin-V (RBCPS), and that this value was not dependent on the presence of calcium in the buffer RBCs treated with AO in the presence of either EDTA, EGTA or calcium exhibited similar percentage of RBCPS. Moreover, the active influx of Zn2+ into RBCs induced by their co-incubation with both ZnCl2 and A23187 did not increase the percent of RBCPS as compared to RBCs incubated with ZnCl2 alone. Taken together, these results demonstrate that the band-3 clustering agents (AO or ZnCl2) induce PS externalization in a Ca2+ independent manner, and we hereby suggest a possible scenario for this phenomenon. BACKGROUND Diuretics have been reported as effective for reducing obstructive sleep apnea (OSA) severity by preventing fluid retention and reducing rostral fluid shift. The benefit of diuretics might vary depending upon the OSA clinical phenotype and comorbidities. To test this hypothesis, we conducted a propensity score-matched cohort analysis of data from the French national sleep apnea registry "Observatoire Sommeil de la Fédération de Pneumologie" (OSFP). METHODS A propensity score analysis was used to determine the impact of diuretics on OSA severity. Matching (ratio 14) was performed by using a 0.1 collider for the propensity score. Severe OSA was defined as an apnea-hypopnea index (AHI) > 30 events/h and the usefulness of diuretics was assessed using a logistic regression model. RESULTS The 69,564 OSA patients studied in the OSFP prospective observational cohort had a median age of 56.9 years [Interquartile range (IQR) 47.4; 65.6], 67% were men, and the median AHI was 28 [14; 43] events/h. Among them, 9,783 (14.1%) were treated with diuretics. Diuretics reduced OSA severity in overweight or moderately obese patients (p=0.03) and in patients with hypertension (p less then 0.01), particularly in hypertensives with a body mass index between 25 and 35 kg/m2 (p less then 0.01). Diuretics had no significant effect on OSA severity in patients with self-reported low physical activity or heart failure. CONCLUSIONS Diuretics appear to have a positive impact on OSA severity in overweight or moderately obese patients with hypertension. A prospective study is needed to confirm that diuretics are of interest in combined therapies for hypertensive patients with OSA. BACKGROUND Extracorporeal membrane oxygenation (ECMO) is rapidly becoming a mainstream technology for lung or heart/lung support. Current ECMO devices mostly consist of a power-driven centrifugal pump and a dedicated oxygenator. We studied the safety and efficacy of a novel, fully pneumatically-driven ECMO device, which could be used in both veno-venous or veno-arterial mode in an animal model. METHODS Six healthy, awake sheep were treated with the Mobybox ECMO device (Hemovent, Aachen, Germany) over a 7-day period in a veno-venous mode. Gas exchange, coagulation parameters and safety were assessed. RESULTS Using a blood flow rate of 2 L/min and a low sweep gas flow rate of 0.3 L/min, the PCO2 ranged from 38-44 mmHg pre oxygenator and dropped to 32-36 mmHg post oxygenator, whereas the PaO2 post oxygenator increased to 600 mmHg. Higher levels of sweep gas flow resulted in cessation of spontaneous breathing in some animals, consistent with high-efficiency carbon dioxide removal; thus, the sweep gas flow rate was maintained at a low level. Platelets dropped from 177±53/μL to 107±28/μL on day two, while returning to baseline by day seven (180±51/μL). Plasma-free hemoglobin remained low (2-9 mg/dl), whereas fibrinogen slightly increased, and then remained stable throughout the period. Neither the pump nor the oxygenator showed any visible clotting after 7 days. CONCLUSIONS The pneumatically-driven ECMO device provides excellent safety and physiologic efficacy in a 7-day sheep experiment without visible clotting, hemolysis, or sustained reductions in fibrinogen or platelets.

These infections can be prevented by a highly effective vaccine and we recommend that the Japanese government resume proactive recommendations for the HPV vaccine immediately.Advanced glycation end-products (AGEs) are formed by the non-enzymatic reaction of sugars and proteins. Among the AGEs, glyceraldehyde-derived toxic AGEs (TAGE) are associated with various diseases, including diabetic complications such as diabetic retinopathy (DR). The risk of developing DR is strongly associated with poor glycemic control, which causes AGE accumulation and increases AGE-induced vascular permeability. We previously reported that Ras guanyl nucleotide releasing protein 2 (RasGRP2), which activates small G proteins, may play an essential role in the cell response to toxicity when exposed to various factors. However, it is not known whether RasGRP2 prevents the adverse effects of TAGE in vascular endothelial cells. This study observed that TAGE enhanced vascular permeability by disrupting adherens junctions and tight junctions via complex signaling, such as ROS and non-ROS pathways. In particular, RasGRP2 protected adherens junction disruption, thereby suppressing vascular hyper-permeability. These results indicate that RasGRP2 is an essential protective factor of vascular permeability and may help develop novel therapeutic strategies for AGE-induced DR.The pelagic spring bloom is essential for Arctic marine food webs, and a crucial driver of carbon transport to the ocean depths. https://www.selleckchem.com/TGF-beta.html A critical challenge is understanding its timing and magnitude, to predict its changes in coming decades. Spring bloom onset is typically light-limited, beginning when irradiance increases or during ice breakup. Here we report an acute 9-day under-ice algal bloom in nutrient-poor, freshwater-influenced water under 1-m thick sea ice. It was dominated by mixotrophic brackish water haptophytes (Chrysochromulina/ Prymnesium) that produced 5.7 g C m-2 new production. This estimate represents about half the annual pelagic production, occurring below sea ice with a large contribution from the mixotrophic algae bloom. The freshwater-influenced, nutrient-dilute and low light environment combined with mixotrophic community dominance implies that phagotrophy played a critical role in the under-ice bloom. We argue that such blooms dominated by potentially toxic mixotrophic algae might become more common and widespread in the future Arctic Ocean.Extraperitoneal colostomy is a widely used technique during abdominoperineal resection (APR) operation for lower rectal cancer. This technique has been reported to be effective to prevent the postoperative parastomal hernia in some retrospective studies, however, there is still a certain incidence of parastomal hernia. A modification of the extraperitoneal colostomy technique is described in this paper that keeps posterior rectal sheath intact instead of having a conventional incision, to further reduce the risk of parastomal hernia. Until now, this modified technique has been performed in 15 patients, no occurrence of parastomal hernia was observed.Exploitation of fisheries and aquaculture practices are exposing marine fish populations to increasing genetic risks. Therefore, the integration of genetic information into fisheries and aquaculture management is becoming crucial to ensure species' long-term persistence. The raising commercial value of grey mullet (Mugil cephalus) and its roe represents a growing challenge to the sustainable management of this economically important fishery resource. Here, microsatellites were used to investigate patterns of genetic variation in a Mediterranean area that harbor flourishing fisheries and practice semi-intensive farming of grey mullet. Genetic diversity within populations is smaller than values reported in previous studies as a result of the lower polymorphism displayed by the new microsatellite loci. Lack of genetic structuring points to the existence of a unique genetic stock, which is consistent with the species' high dispersal capabilities. Nonetheless, differences in local population effective size as well as the excess of related individuals do not completely fit the picture of a large panmictic population. Baseline genetic information here gathered will allow to set up the genetic monitoring of regional fish stocks, which is needed to assess the impact of both harvesting and aquaculture on the genetic integrity of Mugil cephalus wild populations.Between 2009 and 2013, a large cross-sectional study on the health consequences of the Chernobyl nuclear accident was performed in the contaminated and uncontaminated territories of the Bryansk Oblast (Russian Federation). The objective of this work was to confirm or refute a possible association between childhood cardiac arrhythmia and a chronic exposure to caesium-137. As part of this study, a large number of electrocardiographic and cardiac ultrasound parameters were collected from 18,152 children aged 2-18 years including 12,512 healthy ones not contaminated with caesium-137. It seemed therefore relevant for us to share in a second publication these medical data based on healthy and uncontaminated children with the scientific community because of the large quantities and the limited availability of such kind of data. In the present study, relating to electrocardiographic parameters, the measurements performed fully reflect the expected evolution of the paediatric electrocardiogram between 5 and 18 years of age. Thus, the median values were generally quite close to those available in the literature. In contrast, differences in the 2nd and 98th percentiles were notable and could be explained in particular by the type of equipment used, the number of subjects included in the study and racial disparities. As for echocardiographic parameters, the evolution of the measured values in age groups is consistent with what was expected considering factors such as growth. In comparison with other scientific studies that have investigated these echocardiographic parameters, some differences by age groups have been identified. The ethnic factor truly appears to be a relevant feature to consider. In view of the results, it appeared essential to the authors to approach the methodological conditions of the scientific studies already published on the topic to be truly comparable and thus to provide a reliable answer on a topic for which real expectations in terms of medical care are required.

The peptide-free state of these molecules is not well understood. Here, we characterize a disulfide-stabilized version of the human class I molecule HLA-A*0201 that is stable in the absence of peptide and can readily exchange cognate peptides. We present X-ray crystal structures of the peptide-free state of HLA-A*0201, together with structures that have dipeptides bound in the A and F pockets. These structural snapshots reveal that the amino acid side chains lining the binding pockets switch in a coordinated fashion between a peptide-free unlocked state and a peptide-bound locked state. Molecular dynamics simulations suggest that the opening and closing of the F pocket affects peptide ligand conformations in adjacent binding pockets. We propose that peptide binding is co-determined by synergy between the binding pockets of the MHC molecule.The tripartite-motif protein, TRIM5α, is an innate immune sensor that potently restricts retrovirus infection by binding to human immunodeficiency virus capsids. Higher-ordered oligomerization of this protein forms hexagonally patterned structures that wrap around the viral capsid, despite an anomalously low affinity for the capsid protein (CA). Several studies suggest TRIM5α oligomerizes into a lattice with a symmetry and spacing that matches the underlying capsid, to compensate for the weak affinity, yet little is known about how these lattices form. Using a combination of computational simulations and electron cryo-tomography imaging, we reveal the dynamical mechanisms by which these lattices self-assemble. Constrained diffusion allows the lattice to reorganize, whereas defects form on highly curved capsid surfaces to alleviate strain and lattice symmetry mismatches. Statistical analysis localizes the TRIM5α binding interface at or near the CypA binding loop of CA. These simulations elucidate the molecular-scale mechanisms of viral capsid cellular compartmentalization by TRIM5α.Mining, water-reservoir impoundment, underground gas storage, geothermal energy exploitation and hydrocarbon extraction have the potential to cause rock deformation and earthquakes, which may be hazardous for people, infrastructure and the environment. Restricted access to data constitutes a barrier to assessing and mitigating the associated hazards. Thematic Core Service Anthropogenic Hazards (TCS AH) of the European Plate Observing System (EPOS) provides a novel e-research infrastructure. The core of this infrastructure, the IS-EPOS Platform (tcs.ah-epos.eu) connected to international data storage nodes offers open access to large grouped datasets (here termed episodes), comprising geoscientific and associated data from industrial activity along with a large set of embedded applications for their efficient data processing, analysis and visualization. The novel team-working features of the IS-EPOS Platform facilitate collaborative and interdisciplinary scientific research, public understanding of science, citizen science applications, knowledge dissemination, data-informed policy-making and the teaching of anthropogenic hazards related to georesource exploitation. TCS AH is one of 10 thematic core services forming EPOS, a solid earth science European Research Infrastructure Consortium (ERIC) (www.epos-ip.org).The emergence of small open reading frame (sORF)-encoded peptides (SEPs) is rapidly expanding the known proteome at the lower end of the size distribution. Here, we show that the mitochondrial proteome, particularly the respiratory chain, is enriched for small proteins. Using a prediction and validation pipeline for SEPs, we report the discovery of 16 endogenous nuclear encoded, mitochondrial-localized SEPs (mito-SEPs). https://www.selleckchem.com/products/Rapamycin.html Through functional prediction, proteomics, metabolomics and metabolic flux modeling, we demonstrate that BRAWNIN, a 71 a.a. peptide encoded by C12orf73, is essential for respiratory chain complex III (CIII) assembly. In human cells, BRAWNIN is induced by the energy-sensing AMPK pathway, and its depletion impairs mitochondrial ATP production. In zebrafish, Brawnin deletion causes complete CIII loss, resulting in severe growth retardation, lactic acidosis and early death. Our findings demonstrate that BRAWNIN is essential for vertebrate oxidative phosphorylation. We propose that mito-SEPs are an untapped resource for essential regulators of oxidative metabolism.Cancer chemotherapy targeting frequent loss of heterozygosity events is an attractive concept, since tumor cells may lack enzymatic activities present in normal constitutional cells. To find exploitable targets, we map prevalent genetic polymorphisms to protein structures and identify 45 nsSNVs (non-synonymous small nucleotide variations) near the catalytic sites of 17 enzymes frequently lost in cancer. For proof of concept, we select the gastrointestinal drug metabolic enzyme NAT2 at 8p22, which is frequently lost in colorectal cancers and has a common variant with 10-fold reduced activity. Small molecule screening results in a cytotoxic kinase inhibitor that impairs growth of cells with slow NAT2 and decreases the growth of tumors with slow NAT2 by half as compared to those with wild-type NAT2. Most of the patient-derived CRC cells expressing slow NAT2 also show sensitivity to 6-(4-aminophenyl)-N-(3,4,5-trimethoxyphenyl)pyrazin-2-amine (APA) treatment. These findings indicate that the therapeutic index of anti-cancer drugs can be altered by bystander mutations affecting drug metabolic genes.Lipin/Pah phosphatidic acid phosphatases (PAPs) generate diacylglycerol to regulate triglyceride synthesis and cellular signaling. Inactivating mutations cause rhabdomyolysis, autoinflammatory disease, and aberrant fat storage. Disease-mutations cluster within the conserved N-Lip and C-Lip regions that are separated by 500-residues in humans. To understand how the N-Lip and C-Lip combine for PAP function, we determined crystal structures of Tetrahymena thermophila Pah2 (Tt Pah2) that directly fuses the N-Lip and C-Lip. Tt Pah2 adopts a two-domain architecture where the N-Lip combines with part of the C-Lip to form an immunoglobulin-like domain and the remaining C-Lip forms a HAD-like catalytic domain. An N-Lip C-Lip fusion of mouse lipin-2 is catalytically active, which suggests mammalian lipins function with the same domain architecture as Tt Pah2. HDX-MS identifies an N-terminal amphipathic helix essential for membrane association. Disease-mutations disrupt catalysis or destabilize the protein fold. This illustrates mechanisms for lipin/Pah PAP function, membrane association, and lipin-related pathologies.

Eosinophilic fasciitis (EF) is a rare form of fibrosing disorder associated with peripheral eosinophilia with scleroderma-like skin induration and fasciitis in the extremities resulting in painful swelling, erythema and progressive contracture. We present a case report of EF and a literature review to raise awareness of this unusual condition and also highlight key features in its management.Traumatic fractures involving an ununited olecranon apophysis in adults have been rarely documented in the literature. We present the case of a 21-year-old male wrestler with an elbow injury after a fall. Imaging revealed an acute fracture of the olecranon with sclerotic rounded edges indicating an injury through a persistent olecranon apophysis. Open reduction and internal fixation was performed with plate fixation and bone grafting with radiographic and clinical healing at 6 weeks. Review of the literature revealed 5 case reports showing high rates of non-union with tension band constructs while plate and screw fixation had no incidence of nonunion. Fractures through an ununited olecranon apophysis are successfully treated with plate and screw fixation with bone grafting.Background Different techniques are used to release simple and complex congenital syndactyly in order to create an adequate web space, and to separate the fingers to allow independent function. Methods This article is a systematic review of the literature, aiming to evaluate the evidence for the different techniques and outcome measures utilised. Results The studies consisted mainly of retrospective, non-controlled descriptive series and a few retrospective cohort studies. The level of evidence is predominantly poor. Conclusions Although recommendations in favour of any particular surgical technique cannot be given based on evidence, a number of conclusions can be drawn out of the existing literature with regards to the design of the incisions for finger separation, use of pulp flaps and grafts.This case report presents a very rare fracture combination in a perilunate dislocation including the scaphoid, capitate, hamate and triquetrum and the cornu anterior of the lunate, with an intact scapholunate ligament in a left wrist. An open reduction and internal fixation of the scaphoid, capitate, hamate and triquetrum was performed.Extensor tendon rupture of the finger is a very rare complication of Kienböck's disease. However, advanced Kienböck's disease can cause an attritional rupture of extensor tendons due to displaced lunate fragment. An extensor tendon of the thumb is frequently damaged in the distal radial fracture, and an extensor tendon of the fifth finger is mainly ruptured in arthritis of distal radio-ulnar joint. On the other hand, the extensor tendons of the 2nd, 3rd and 4th fingers are usually ruptured in advanced Kienböck's disease. We report two elderly patients diagnosed with advanced Kienböck's disease after non-traumatic rupture of extensor tendon of the fingers. Since the extensor tendon rupture in Kienböck's disease present as a loss of active extension of metacarpophalangeal joint in the central fingers, these patients should undergo imaging of the wrist joints to ascertain concomitant Kienböck's disease.Background Postoperative results of ulnar shortening osteotomy for ulnar abutment syndrome were compared between groups of patients in whom the plate was placed on the volar side and those in whom the plate was placed on the dorsal side. Methods A total of 35 wrists of 14 males and 21 females were evaluated. The average age of patients at surgery was 44.3 years, and the average follow-up period was 66.2 months. After transverse osteotomy was performed, the ulna was fixed using a 6-hole LC-LCP or a LC-DCP on the dorsal (group D) or the volar (group V) side, respectively. Imaging and clinical results, rates and reasons for implant removal were evaluated. Results There were 27 patients in group D and 8 in group V. A significant difference was observed only in the postoperative grip strength compared with that of the unaffected side between groups V and D (102% and 87%, respectively). Implant removal was performed in 18 (64%) patients in group D and in 7 (88%) in group V, and the main reasons for this were pain in group V and discomfort in group D. Re-fracture occurred after implant removal in one patient in group D. Conclusions There were no differences in the imaging and clinical results depending on the plate position. It is preferable to avoid implant removal by placing the lower profile plate on the dorsal side.Background A new beta-tricalcium phosphate with unidirectional pore structure (UDPTCP), Affinos® (Kurray, Okayama, Japan), has been in clinical use since 2015. To date, there have been only a few clinical studies using this material. We report here the first clinical study for distal radial fracture in the elderly population treated with UDPTCP. Methods Consecutive patients aged 65 years or older with dorsally displaced unstable fracture of the distal radius (n = 36) were treated operatively in our department. Following reduction of the fracture site, a 7 mm size cube of UDPTCP was placed in the gap of the bony defect and the fracture stabilized with mono-axial or poly-axial type locking plates and screws. Remodeling of the UDPTCP was evaluated by plain radiograph and clinical outcomes were also assessed. Results UDPTCP was significantly resorbed at 2 months after surgery, both at the center and periphery of the material. Complications were only observed in the post-operative period. Significant correction loss of radial alignment was seen in patients stabilized with poly-axial locking plate. The clinical outcome in all cases was excellent. Conclusions Block UDPTCP is a safe and convenient material for the treatment of distal radius fracture and is replaced within a suitable time period after grafting into the fracture site. UDPTCP and stable internal fixation is therefore a reliable strategy for restoring and preserving anatomical position, especially in the elderly population.Background This study aimed to describe a novel surgical technique in which a bridge plate was used for the treatment of hamatometacarpal fracture-dislocations and to assess its radiologic and clinical outcomes. Methods A retrospective review of 16 patients treated with the bridge plate technique for hamatometacarpal fracture-dislocations was performed between 2010 and 2015. Clinical and radiographic evaluations were performed at months 3, 6, and 12 postoperatively. https://www.selleckchem.com/products/LBH-589.html Active wrist and metacarpophalangeal joint ranges of motion and Quick Disabilities of Arm, Shoulder, and Hand (DASH) scores were recorded for the injured hands. Grip strength data were collected for both the injured hands and the contralateral uninjured hands. Results All patients included in our study were male (mean age 31 years). The average Quick DASH score was 24.3 ± 9.1 at 3 months, 12.3 ± 7.3 at 6 months, and 6.2 ± 6.6 at 12 months. All patients returned to their original jobs within 5 weeks of the procedure. Grip strength eventually recovered to 90% of that of the uninjured hand, and none of the patients complained of finger or wrist joint stiffness.

Meanwhile, since there is no ground truth for the feature maps generated by the AD-LSTM, we propose an adversarial learning algorithm to optimize the AD-LSTM. With the help of adversarial learning, the Siamese network can generate the response maps more accurately, and the AD-LSTM can generate the feature maps of the target more robustly. The experimental results show that our tracker performs favorably against the state-of-the-art trackers on six challenging benchmarks OTB-100, TC-128, VOT2016, VOT2017, GOT-10k, and TrackingNet.Understanding correlation judgement is important to designing effective visualizations of bivariate data. Prior work on correlation perception has not considered how factors including prior beliefs and uncertainty representation impact such judgements. The present work focuses on the impact of uncertainty communication when judging bivariate visualizations. Specifically, we model how users update their beliefs about variable relationships after seeing a scatterplot with and without uncertainty representation. To model and evaluate the belief updating, we present three studies. Study 1 focuses on a proposed "Line + Cone" visual elicitation method for capturing users' beliefs in an accurate and intuitive fashion. The findings reveal that our proposed method of belief solicitation reduces complexity and accurately captures the users' uncertainty about a range of bivariate relationships. https://www.selleckchem.com/products/OSI-906.html Study 2 leverages the "Line + Cone" elicitation method to measure belief updating on the relationship between different sets of variables when seeing correlation visualization with and without uncertainty representation. We compare changes in users beliefs to the predictions of Bayesian cognitive models which provide normative benchmarks for how users should update their prior beliefs about a relationship in light of observed data. The findings from Study 2 revealed that one of the visualization conditions with uncertainty communication led to users being slightly more confident about their judgement compared to visualization without uncertainty information. Study 3 builds on findings from Study 2 and explores differences in belief update when the bivariate visualization is congruent or incongruent with users' prior belief. Our results highlight the effects of incorporating uncertainty representation, and the potential of measuring belief updating on correlation judgement with Bayesian cognitive models.Synthesizing realistic 3D mesh deformation sequences is a challenging but important task in computer animation. To achieve this, researchers have long been focusing on shape analysis to develop new interpolation and extrapolation techniques. However, such techniques have limited learning capabilities and therefore often produce unrealistic deformation. Although there are already networks defined on individual meshes, deep architectures that operate directly on mesh sequences with temporal information remain unexplored due to the following major barriers irregular mesh connectivity, rich temporal information, and varied deformation. To address these issues, we utilize convolutional neural networks defined on triangular meshes along with a shape deformation representation to extract useful features, followed by long short-term memory(LSTM) that iteratively processes the features. To fully respect the bidirectional nature of actions, we propose a new share-weight bidirectional scheme to better synthesize deformations. An extensive evaluation shows that our approach outperforms existing methods in sequence generation, both qualitatively and quantitatively.In the last two decades, interactive visualization and analysis have become a central tool in data-driven decision making. Concurrently to the contributions in data visualization, research in data management has produced technology that directly benefits interactive analysis. Here, we contribute a systematic review of 30 years of work in this adjacent field, and highlight techniques and principles we believe to be underappreciated in visualization work. We structure our review along two axes. First, we use task taxonomies from the visualization literature to structure the space of interactions in usual systems. Second, we created a categorization of data management work that strikes a balance between specificity and generality. Concretely, we contribute a characterization of 131 research papers along these two axes. We find that five notions in data management venues fit interactive visualization systems well materialized views, approximate query processing, user modeling and query prediction, muiti-query optimization, lineage techniques, and indexing techniques. In addition, we find a preponderance of work in materialized views and approximate query processing, most targeting a limited subset of the interaction tasks in the taxonomy we used. This suggests natural avenues of future research both in visualization and data management. Our categorization both changes how we visualization researchers design and build our systems, and highlights where future work is necessary.How do analysts think about grouping and spatial operations? This overarching research question incorporates a number of points for investigation, including understanding how analysts begin to explore a dataset, the types of grouping/spatial structures created and the operations performed on them, the relationship between grouping and spatial structures, the decisions analysts make when exploring individual observations, and the role of external information. This work contributes the design and results of such a study, in which a group of participants are asked to organize the data contained within an unfamiliar quantitative dataset. We identify several overarching approaches taken by participants to design their organizational space, discuss the interactions performed by the participants, and propose design recommendations to improve the usability of future high-dimensional data exploration tools that make use of grouping (clustering) and spatial (dimension reduction) operations.Recently, infrared small target detection problem has attracted substantial attention. Many works based on local low-rank model have been proven to be very successful for enhancing the discriminability during detection. However, these methods construct patches by traversing local images and ignore the correlations among different patches. Although the calculation is simplified, some texture information of the target is ignored, and targets of arbitrary forms cannot be accurately identified. In this paper, a novel target-aware method based on a non-local low-rank model and saliency filter regularization is proposed, with which the newly proposed detection framework can be tailored as a non-convex optimization problem, therein enabling joint target saliency learning in a lower dimensional discriminative manifold. More specifically, non-local patch construction is applied for the proposed target-aware low-rank model. By combining similar patches, we reconstruct them together to achieve a better generalization of non-local spatial sparsity constraints.

This work contributes the design and results of such a study, in which a group of participants are asked to organize the data contained within an unfamiliar quantitative dataset. We identify several overarching approaches taken by participants to design their organizational space, discuss the interactions performed by the participants, and propose design recommendations to improve the usability of future high-dimensional data exploration tools that make use of grouping (clustering) and spatial (dimension reduction) operations.Recently, infrared small target detection problem has attracted substantial attention. Many works based on local low-rank model have been proven to be very successful for enhancing the discriminability during detection. However, these methods construct patches by traversing local images and ignore the correlations among different patches. Although the calculation is simplified, some texture information of the target is ignored, and targets of arbitrary forms cannot be accurately identified. In this paper, a novel target-aware method based on a non-local low-rank model and saliency filter regularization is proposed, with which the newly proposed detection framework can be tailored as a non-convex optimization problem, therein enabling joint target saliency learning in a lower dimensional discriminative manifold. More specifically, non-local patch construction is applied for the proposed target-aware low-rank model. By combining similar patches, we reconstruct them together to achieve a better generalization of non-local spatial sparsity constraints.

Erich Letterer (1895-1982) is without any doubt one of the most renowned German pathologists of the 20th century. As the eponym of the "Letterer-Siwe disease" and as a pioneer in the field of immunopathology, he made his mark in medical history. Less well known is the fact that Letterer achieved the decisive career step - the call to a full professorship - in the Third Reich, at the explicit request of authoritative National Socialists. In post-war Germany, on the other hand, Letterer was considered a politically unencumbered, honorable scientist. But how do these findings fit together? Did Letterer serve the Nazi regime or did he achieve his high positions despite a politically unbending, straightforward attitude? These questions are the main focus of the present article, which also traces Letterer's academic career and oeuvre. The paper is based on primary sources from various federal and regional archives, most of which have been evaluated for the first time; they have been compared and supplemented with the existing secondary literature. It concludes that Letterer was politically loyal during the Nazi era - as evidenced by memberships in various Nazi organizations - and that he enjoyed political support. Letterer's self-image of a politically aloof, blameless scholar does not agree with the sources. However, Letterer did not belong to those university lecturers who owed their career in the Third Reich mainly to political reasons. https://www.selleckchem.com/products/Rapamycin.html Rather, he was a renowned pathologist and scientist who also proved to be politically reliable in the decisive phase of his career.Primary mediastinal germ cell tumors with somatic malignancies are rare. We report a case of a 34-year old man with melanoma arising in a primary mediastinal mixed germ cell tumor. On initial biopsy, the patient was found to have a germ cell tumor containing yolk sac and embryonal components only. After chemotherapy, histopathological evaluation of the residual tumor in the wide local resection specimen revealed a mature teratoma with melanoma. Molecular studies demonstrated that the residual germ cell tumor harbored KIT and NRAS mutations associated with malignant melanoma. Multiple Sclerosis (MS) and Migraine are comorbid neurologic conditions. Migraine prevalence is three times higher in the MS clinic population compared to the general population, and patients with MS and migraine are more symptomatic than patients with MS without migraine. We sought to conduct a pilot feasibility and acceptability study of the RELAXaHEAD app in MS-Migraine patients and to assess whether there was any change in migraine disability and MS pain-related disability. Randomized controlled study of patients with MS-migraine ages 18-80 years with 4+ headache days/ month who were willing to engage in smartphone based behavioral therapy. Half received the RELAXaHEAD app with progressive muscle relaxation (PMR) and the other half received the app without the PMR. Data was collected for 90 days on measures of recruitment, retention, engagement, and adherence to RELAXaHEAD. Preliminary data was also collected on migraine disability (MIDAS) and MS pain (PES). Sixty-two subjects with MS-migraine wer-based interactions, follow up was challenging, but those reached indicated that they appreciated the PMR and would recommend it to others. Future work should focus on engagement and efficacy. There was interest in scalable accessible forms of behavioral therapy to treat migraine and MS-related pain in patients with MS and comorbid migraine. Similar to prior studies, a significant minority were willing to practice the PMR at least twice weekly. In the societal shift from telephone to more text and internet-based interactions, follow up was challenging, but those reached indicated that they appreciated the PMR and would recommend it to others. Future work should focus on engagement and efficacy. Whether the prognosis of tongue cancer differs between young patients and elderly patients remains controversial. We aimed to compare the clinical characteristics and prognoses of patients with young-onset and old-onset tongue cancer. The retrospective cohort study utilized data from the Diagnosis Procedure Combination database maintained in Japan. Data derived from patients age≥20years diagnosed with tongue cancer between April 2008 and January 2019 were extracted from the database. Patients were divided into two groups based on age at tongue cancer diagnosis, a<45years group and a≥45years group. The primary outcomes were overall survival and disease-free survival, adjusted for age, sex, tumor classification, nodal metastasis, distant metastasis, smoking history, Charlson Comorbidity Index score, and tongue cancer treatment. A total of 2315 patients diagnosed with tongue cancer were included in the study, of whom 1412 patients diagnosed based on the seventh edition of the Union for International Cancer Control in the multivariable Cox proportional hazards modeling. The adjusted hazard ratio for overall survival was 1.22 (95% confidence interval 0.66-2.24, p=0.54) and that for disease-free survival was 1.14 (95% confidence interval 0.80-1.61, p=0.47), and neither differed significantly between the two age groups. The results of the present study suggest that younger age at the time of tongue cancer diagnosis may not be associated with a poorer prognosis. Young patients with tongue cancer should be treated in accordance with general guidelines. The results of the present study suggest that younger age at the time of tongue cancer diagnosis may not be associated with a poorer prognosis. Young patients with tongue cancer should be treated in accordance with general guidelines.Background Fetal growth restriction (FGR), defined as an estimated fetal weight (EFW)95th percentile (n = 1) compared to AGA fetuses. Strain rate was measured in two studies. One reported an increased strain rate, another showed comparable strain rate. Two studies addressed global left ventricle (LV) and right ventricle (RV) dyssynchrony. Dyssynchrony was increased in FGR compared to AGA fetuses. Conclusion The currently published data is limited and heterogeneous concerning GA and Doppler profiles. The data presentation and the interpretation thereof make qualitative comparisons impossible. Large prospective longitudinal cohort studies looking at the value of deformation measurements of the fetal heart in FGR and AGA fetuses are needed to assess the clinical significance of deformation values measured with 2D-STE.

In this review we discuss the evidence implicating the MPC as an important, perhaps causal, mediator of heart failure progression.Ubiquitination is an essential post-translational modification that regulates most cellular processes. The assembly of ubiquitin into polymeric chains by E3 ubiquitin ligases underlies the pleiotropic functions ubiquitin chains regulate. Ubiquitin chains assembled via the N-terminal methionine, termed Met1-linked ubiquitin chains or linear ubiquitin chains, have emerged as essential signalling scaffolds that regulate pro-inflammatory responses, anti-viral interferon responses, cell death and xenophagy of bacterial pathogens downstream of innate immune receptors. Met1-linked ubiquitin chains are exclusively assembled by the linear ubiquitin chain assembly complex, LUBAC, and are disassembled by the deubiquitinases OTULIN and CYLD. Genetic defects that perturb the regulation of Met1-linked ubiquitin chains causes severe immune-related disorders, illustrating their potent signalling capacity. Here, we review the current knowledge about the cellular machinery that conjugates, recognises, and disassembles Met1-linked ubiquitin chains, and discuss the function of this unique posttranslational modification in regulating inflammation, cell death and immunity to pathogens. Insulin resistance (IR) is a pathophysiological construct that derives a series of metabolic disturbances that promote cardiometabolic dysfunction. This study evaluated mediating and modifying effects of homeostatic model assessment-based IR (HOMA-IR) on the association between sugar-sweetened beverage (SSB) consumption and a constellation of adolescent cardiometabolic abnormalities. Comprehensive data on sociodemographics, diet, physical activity, and anthropometric and biochemical parameters for 1454 adolescents were obtained from a large-scale representative study for adolescent metabolic syndrome (MetS) conducted in Taiwan. The original (HOMA1-IR) and updated nonlinear (HOMA2-IR) HOMA-IR indicators were used as IR biomarkers. Principal component (PC) analysis was employed to create reduced groups of variables and risk scores for retained PCs. Higher SSB intake was associated with higher levels of HOMA1-IR and HOMA2-IR, and the two IR biomarkers were positively correlated with metabolic dysfunction cescents, and this association may be partly mediated by HOMA-IR levels. The adverse effects of HOMA-IR on bodyweight-associated cardiometabolic risk factors depend on the type of SSB consumption, with enhanced risks observed in the intake of high amounts of HFCS-containing SSBs. We investigated the efficacy and safety of liraglutide 3 mg daily in combination with diet and exercise 2, 4, and 6 months after initiation in real-world settings in Korea. People first using liraglutide starting in 2018 were recruited from ten sites in Korea. Body weight and body mass index (BMI) were measured after 2, 4, and 6 months and compared with baseline values. The full cohort comprised 769 participants 672 in the 2-month group, 427 in the 4-month group, and 219 in the 6-month group. The baseline mean ± standard deviation of BMI and body weight were 32.2 ± 5.1 kg/m , and 87.5 ± 18.8 kg, respectively. Body weight and BMI decreased after initiation of liraglutide treatment -2.94 kg and -1.08 kg/m at 2 months; -4.23 kg and -1.55 kg/m at 4 months, and -5.14 kg and -1.89 kg/m at 6 months (all P < 0.001). In the 6-month cohort, 52.5% and 18.3% of subjects lost ≥5% and ≥10% of body weight, respectively. After 6 months, systolic and diastolic blood pressure decreased significantly by 3.90 and 1.93 mmHg, respectively. In those with diabetes mellitus, HbA1c and fasting glucose levels decreased significantly by 1.14% and 27.8 mg/dl, respectively. Among all participants, 27.6% experienced adverse effects, including nausea (20.8%), vomiting (5.2%), diarrhoea (2.5%), and skin rash (3.6%). Documented reasons for discontinuation of treatment were lack of effect (4.4%), adverse events (4.3%), and high cost (3.1%). In real-world settings in Korea, daily treatment with liraglutide 3 mg was associated with clinically meaningful weight loss without serious adverse events. In real-world settings in Korea, daily treatment with liraglutide 3 mg was associated with clinically meaningful weight loss without serious adverse events. To investigate (1) the association of four VDR polymorphisms (TaqI/rs731236, ApaI/rs7975232, FokI/rs10735810, and Bsml/rs1544410) with markers of adiposity and tissue-specific insulin resistance at baseline, after weight loss and weight maintenance; (2) the effect of the VDR polymorphisms in the SAT transcriptome in overweight/obese Caucasians of the DiOGenes cohort. We included 553 adult obese individuals (mean BMI 34.8 kg/m ), men (n = 197) and women (n = 356) at baseline, following an 8-week weight loss intervention and 26 weeks weight maintenance. Genotyping was performed using an Illumina 660W-Quad SNP chip on the Illumina iScan Genotyping System. Tissue-specific IR was determined using Hepatic Insulin Resistance Index (HIRI), Muscle Insulin Sensitivity Index (MISI), and Adipose Tissue Insulin Resistance Index (Adipo-IR). Expression quantitative trait loci (eQTL) analysis was performed to determine the effect of SNPs on SAT gene expression. None of the VDR polymorphisms were associated with HIRI oicating that putative mechanisms of action remain to be determined. Finally, VDR SNPs did not affect dietary intervention outcome in the present cohort. Although excess visceral fat (VAT) is associated with numerous cardio-metabolic risk factors, measurement of this fat depot has historically been difficult. Recent dual X-ray absorptiometry approaches have provided an accessible estimate of VAT that has shown acceptable validity against gold standard methods. The aims of this study were to (i) evaluate DXA measured VAT as a predictor of elevated blood lipids and blood pressure and (ii) calculate thresholds associated with these cardio-metabolic risk factors. The sample comprised 1482 adults (56.4% women) aged 18-66 years. Total body scans were performed using a GE Lunar Prodigy, and VAT analyses were enabled through Corescan software (v 16.0). Blood pressure and blood lipids were measured by standard procedures. Regression models assessed how VAT mass was associated with each cardio-metabolic risk factor compared to other body composition measures. https://www.selleckchem.com/JAK.html Measures of sensitivity and specificity were used to determine age- and sex-specific cut points for VAT mass associated with high cardio-metabolic risk.

Background The development of novel revascularization devices has improved procedural and clinical outcomes in acute ischemic stroke (AIS). A direct aspiration first pass technique (ADAPT) has been introduced as a rapid simple method for achieving good recanalization and clinical outcomes using large bore aspiration catheters in the treatment of AIS due to large vessel occlusion (LVO). Objectives The aim of this study was to assess the safety and efficacy of ADAPT in the treatment of AIS due to LVO in the Vietnamese patient population. Materials and Methods A retrospective analysis of a hospital database was conducted on all patients undergoing stroke therapy with the ADAPT technique at the institution from January 2017 to December 2017. Efficacy and safety were evaluated by the variables revascularization rates (thrombolysis in cerebral infarction [TICI] score), time to revascularization, procedural complications, and clinical outcomes (modified Rankin scale [mRS] score) at the 90-day follow-up visit. Results From the database review, 37 AIS patients treated with ADAPT were identified. https://www.selleckchem.com/products/sodium-pyruvate.html The mean NIHSS score at presentation was 17.3 and improved to 8.9 at discharged. The average time arterial puncture to revascularization was 32.5 min. TICI 2b/3 revascularization was achieved in 30/37 (81.1%) patients, good clinical outcomes were achieved (mRS 0-2) in 21/37 (56.7%) patients, and mortality rate was 6/37 (16.2%) during follow-up. Conclusions ADAPT utilizing large bore aspiration catheters appears to be a fast, simple, safe, and effective method for the management of AIS in the Vietnamese patient population.

In this manuscript, we summarized our early surgical cases of TTS. Materials and Methods Six feet in five patients with TTS were treated surgically. The patients were aged 31-70 years (mean 53.1 years), and all of them complained of pain or dysesthesia of the sole of the foot sparing the heel. Magnetic resonance imaging (MRI) and nerve conduction test were performed preoperatively. In surgery, flexor retinaculum was dissected (tarsal tunnel opening [TTO]), the posterior tibial nerve was freed from the arteriovenous complex (neurovascular decompression [NVD]), and fascia of the abductor hallucis muscle was excised to decompress the medial and lateral plantar nerve (releasing fascial of abductor hallucis muscle [RFAH]). Results Preoperative MRI confirmed that all seven cases were idiopathic TTS. Moreover, NCD demonstrated delayed sensory conduction velocity but not delayed distal motor latency. Surgical decompression was beneficial in 5 feet. The recurrence of symptoms was found in one case within 1 postoperative month. Conclusion Surgical treatment for idiopathic TTS with TTO, NVD, and RFAH was generally good. However, symptoms recurred in one instance. Some methods to prevent adhesion and granulation in the reconstructed tarsal tunnel should be considered.

Aims The aim of this study is to evaluate the incidence of along with risk factors for postoperative VTE in surgically treated extramedullary spinal tumor patients. Setting and Designs The study design involves single institute and retrospective cohort study. Subjects and Methods The cohort database was reviewed between the periods of January 2014 and June 2019. Patients undergoing surgery for spine tumor, extradural tumor, and intradural extramedullary were consecutively collected. Statistical Analysis Used The incidence of VTE and clinical factors reported to be associated with VTE were identified, and then analyzed with an appropriate Cox regression model. Results The study identified 103 extramedullary spinal tumor patients. Three patients (2.9%) were diagnosed with a proximal leg DVT, while symptomatic PE did not identify. Risk factors associated with DVT occurrence were as follows operative time ≥8 h (Hazard ratio [HR] 13.98, P = 0.03) and plasma transfusion (HR 16.38, P = 0.02), whereas plasma transfusion was the only significant factor, after multivariate analysis (HR 11.77, P = 0.05). Conclusions Patients who underwent surgery for extramedullary spinal tumors showed a 2.9% incidence of DVT. The highest rate of DVT was found in patients who received plasma transfusion. More attention should be paid on perioperative associated factors for intensive prevention coupled with early screening in this group.

Freehand EVD, using surface anatomical landmarks, is performed for ventricular cannulation due to its simplicity and efficiency. This study evaluates accuracy and reason(s) for misplacements as few studies have analyzed the accuracy of freehand EVD insertion. Patients and Methods Preoperative and postoperative computed tomography scans of patients who underwent EVD insertion in 2014 were retrospectively reviewed. Diagnosis, Evans ratio, midline shift, position of burr hole, length of the catheter, and procedural complications were tabulated. The procedures were classified as satisfactory (catheter tip in the frontal horn ipsilateral lateral ventricle) and unsatisfactory. Unsatisfactory cases were further analyzed in relation to position of burr hole from midline and length of the catheter. Results Seventy-seven EVD placements in seventy patients were evaluated. The mean age of the patients was 57.5 years. About 83.1% were satisfactory placements and 11.7% were unsatisfactory in the contralateral ventricle, corpus callosum, and interhemispheric fissure. Nearly 5.2% were in extraventricular locations. Almost 2.6% EVD placements were complicated by hemorrhage and 1 catheter was reinserted. Suboptimal placements were significantly associated with longer intracranial catheter length. The mean length was 66.54 ± 10.1 mm in unsatisfactory placements compared to 58.32 ± 4.85 mm in satisfactory placements. Between the two groups, no significant difference was observed in Evans ratio, midline shift, surgeon's experience, distance of burr hole from midline, and coronal suture. Conclusion Freehand EVD insertion is safe and accurate. In small number of cases, unsatisfactory placement is related to longer catheter length. Copyright © 2020 Asian Journal of Neurosurgery.

GO enrichment revealed that they were mainly enriched in binding, catalytic activity, cellular process and cell. KEGG pathway revealed that they were mainly enriched in metabolic pathways, pathways in cancer and PI3K-Akt signaling pathway. MUC5AC, MUC1, KRT7, GAPDH, CD44 were identified from the PPI network. MUC5AC, MUC1, KRT7, GAPDH, CD44 were demonstrated to have prognostic value for patients with GC. MUC5AC, MUC1 exhibited low expression levels in GC tissues, KRT7, GAPDH, CD44 presented high expression levels in GC tissues. In particular, KRT7 is hardly expressed in normal gastric tissues. MUC5AC and MUC1 were negatively correlated with GAPDH, CD44, respectively; and GAPDH was positively correlated with CD44 and KRT7, respectively. Moreover. MUC5AC, MUC1, KRT7, GAPDH, and CD44 are not only related to GC but also to apoptosis pathway. Results from the present study suggested that MUC5AC, MUC1, KRT7, GAPDH, CD44 may represent novel prognostic biomarkers for GC.INTRODUCTION Supportive care development has created new needs in patients' care pathway. In order to anticipate, evaluate, and take care of patients' needs, a supportive care dedicated hospitalization ward was created in late 2016 in our comprehensive cancer center, including 15 beds (11 for week care and 4 for day care). We aimed to assess the activity of this supportive care ward in 2018. METHODS Data were extracted from weekly activity reports of supportive care ward and retrospectively analyzed. Those reports are automatically generated from hospitalization scheduling software. RESULTS In week care ward, 627 stays were recorded. https://www.selleckchem.com/MEK.html Occupancy rate was 88%. Mean stay duration was 3.01 days. Main indications for week stay were pain evaluation and management (47.4%) and nutritional management (31.7%). In day care ward, 1191 stays were registered. Turnover rate was 1.18 patients/bed/day. Main indications for day stay were pain management (41.6%) and comprehensive geriatric assessment in oncology (22.8%). CONCLUSION The 2018 supportive care ward evaluation showed its viability in comprehensive cancer center. The main activity was based on pain and nutritional management.PURPOSE Change in hunger is a common and bothersome symptom among pediatric patients receiving cancer treatments. Objectives were to describe how children and adolescents receiving cancer treatments experience changes in hunger, factors associated with both increases and decreases in hunger, and coping strategies used by these patients. METHODS We enrolled children and adolescents 4-18 years of age with cancer or hematopoietic stem cell transplantation (HSCT) recipients who were actively receiving treatment or who had completed therapy. Using a single, qualitative, semi-structured interview, we asked participants about the experience of increases or decreases in hunger, including characteristics of the change and identified coping strategies. RESULTS There were 50 children enrolled; 25 (50%) were 4-10 years of age and 33 (66%) were boys. Most often, patients associated an increase in hunger with corticosteroid administration, while other treatments, accompanying symptoms, inactivity, and the hospital environment were associated with a decrease in hunger. Many reported that no coping strategies were successful. For those who did report successful strategies to manage an increase in hunger, these included sleep and having food available. Strategies used to manage a decrease in hunger included anti-emetic medications, increased caloric intake, varied food choices, encouragement to eat, scheduling or tracking of meals, and physical activity. CONCLUSIONS Both increases and decreases in hunger were commonly described. Some coping strategies were reported to be successful. Further research should identify and test interventions to manage changes in hunger in pediatric cancer patients.The interaction of a single-chain variable fragment (scFv) directed against human tissue factor (TF) was predicted using an in silico approach with the aim to establish a most likely mechanism of inhibition. The structure of the TF inhibiting scFv (TFI-scFv) was predicted using homology modeling, and complementarity-determining regions (CDRs) were identified. The CDR was utilized to direct molecular docking between the homology model of TFI-scFv and the crystal structure of the extracellular domains of human tissue factor. The rigid-body docking model was refined by means of molecular dynamic (MD) simulations, and the most prevalent cluster was identified. MD simulations predicted improved interaction between TFI-scFv and TF and propose the formation of stable complex for duration of the 600-ns simulation. Analysis of the refined docking model suggests that the interactions between TFI-scFv would interfere with the allosterical activation of coagulation factor VII (FVII) by TF. This interaction would prevent the formation of the active TFVIIa complex and in so doing inhibit the initiation phase of blood coagulation as observers during in vitro testing.The aim of our study is a retrospective evaluation of effectiveness and safety of Computed Tomography (CT)-guided radiofrequency ablation (RFA) therapy of primary and metastatic lung lesions in patients that cannot be considered surgical candidates. From February 2007 to September 2017, we performed 264 CT-guided ablation sessions on 264 lesions in 174 patients (112 M and 62 F; mean age, 68 years; range 36-83 years) affected by primary and metastatic lung lesions. The 45% of patients was affected by primary lung cancer, with size range lesion of 10-50 mm, and the 55% by metastatic lung lesions with size range of 5-49 mm. All patients had no more than three metastases in the lung and pulmonary relapses were treated up to three times. Overall Survival (OS), Progression-Free Survival (PFS), Local Progression-Free Survival (LPFS) and Cancer-specific survival (CSS) at 1, 3 and 5 years were calculated both in primary lung tumors and in metastatic patients. Immediate and late RFA-related complications were reported.nt worsening of pulmonary function was noted. Our retrospective evaluation showed long-term effectiveness, safety and imaging features of CT-guided RFA in patients affected by primary and metastatic lung cancer as an alternative therapy in non-surgical candidates.
