Abstract

Designing adequate and precise neural architectures is a challenging task, often done by highly specialized personnel. AutoML is a machine learning field that aims to generate good performing models in an automated way. Spectral data such as those obtained from biological analysis have generally a lot of important information, and these data are specifically well suited to Convolutional Neural Networks (CNN) due to their image-like shape. In this work we present NASirt, an AutoML methodology based on Neural Architecture Search (NAS) that finds high accuracy CNN architectures for spectral datasets. The proposed methodology relies on the Item Response Theory (IRT) for obtaining characteristics from an instance level, such as discrimination and difficulty, and it is able to define a rank of top performing submodels. Several experiments are performed in order to demonstrate the methodology's performance with different spectral datasets. Accuracy results are compared to other benchmarks methods, such as a high performing, manually crafted CNN and the Auto-Keras AutoML tool. The results show that our method performs, in most cases, better than the benchmarks, achieving average accuracy as high as 97.40%., Comment: to be published

Abstract

Escherichia coli is the most common cause of human and canine urinary tract infection (UTI). Clonal groups, often with high levels of antimicrobial resistance, are a major component of the E. coli population that causes human UTI. While little is known about the population structure of E. coli that causes UTI in dogs, there is evidence that dogs and humans can share fecal strains of E. coli and that human-associated strains can cause disease in dogs. In order to better characterize the E. coli strains that cause canine UTI, we analyzed 295 E. coli isolates obtained from canine urine samples from five veterinary diagnostic laboratories and analyzed their multilocus sequence types, phenotypic and genotypic antimicrobial resistance profiles, and virulence-associated gene repertoires. Sequence type 372 (ST372), an infrequent human pathogen, was the predominant sequence type in dogs at all locations. Extended-spectrum β-lactamase-producing isolates with blaCTX-M genes were uncommon in canine isolates but when present were often associated with sequence types that have been described in human infections. This provides support for occasional cross-host-species sharing of strains that cause extraintestinal disease and highlights the importance of understanding the role of companion animals in the overall transmission patterns of extraintestinal pathogenic E. coli.

Abstract

Background Textbook outcome has been proposed as a tool for the assessment of oncological surgical care. However, an international assessment in patients undergoing oesophagectomy for oesophageal cancer has not been reported. This study aimed to assess textbook outcome in an international setting. Methods Patients undergoing curative resection for oesophageal cancer were identified from the international Oesophagogastric Anastomosis Audit (OGAA) from April 2018 to December 2018. Textbook outcome was defined as the percentage of patients who underwent a complete tumour resection with at least 15 lymph nodes in the resected specimen and an uneventful postoperative course, without hospital readmission. A multivariable binary logistic regression model was used to identify factors independently associated with textbook outcome, and results are presented as odds ratio (OR) and 95 per cent confidence intervals (95 per cent c.i.). Results Of 2159 patients with oesophageal cancer, 39.7 per cent achieved a textbook outcome. The outcome parameter ‘no major postoperative complication’ had the greatest negative impact on a textbook outcome for patients with oesophageal cancer, compared to other textbook outcome parameters. Multivariable analysis identified male gender and increasing Charlson comorbidity index with a significantly lower likelihood of textbook outcome. Presence of 24-hour on-call rota for oesophageal surgeons (OR 2.05, 95 per cent c.i. 1.30 to 3.22; P = 0.002) and radiology (OR 1.54, 95 per cent c.i. 1.05 to 2.24; P = 0.027), total minimally invasive oesophagectomies (OR 1.63, 95 per cent c.i. 1.27 to 2.08; P < 0.001), and chest anastomosis above azygous (OR 2.17, 95 per cent c.i. 1.58 to 2.98; P < 0.001) were independently associated with a significantly increased likelihood of textbook outcome. Conclusion Textbook outcome is achieved in less than 40 per cent of patients having oesophagectomy for cancer. Improvements in centralization, hospital resources, access to minimal access surgery, and adoption of newer techniques for improving lymph node yield could improve textbook outcome.

Abstract

Background: No evidence currently exists characterising global outcomes following major cancer surgery, including esophageal cancer. Therefore, this study aimed to characterise impact of high income countries (HIC) versus low and middle income countries (LMIC) on the outcomes following esophagectomy for esophageal cancer. Method: This international multi-center prospective study across 137 hospitals in 41 countries included patients who underwent an esophagectomy for esophageal cancer, with 90-day follow-up. The main explanatory variable was country income, defined according to the World Bank Data classification. The primary outcome was 90-day postoperative mortality, and secondary outcomes were composite leaks (anastomotic leak or conduit necrosis) and major complications (Clavien-Dindo Grade III-V). Multivariable generalized estimating equation models were used to produce adjusted odds ratios (ORs) and 95% confidence intervals (CI95%). Results: Between April 2018 to December 2018, 2247 patients were included. Patients from HIC were more significantly older, with higher ASA grade, and more advanced tumors. Patients from LMIC had almost three-fold increase in 90-day mortality, compared to HIC (9.4% vs 3.7%, p < 0.001). On adjusted analysis, LMIC were independently associated with higher 90-day mortality (OR: 2.31, CI95%: 1.17-4.55, p = 0.015). However, LMIC were not independently associated with higher rates of anastomotic leaks (OR: 1.06, CI95%: 0.57-1.99, p = 0.9) or major complications (OR: 0.85, CI95%: 0.54-1.32, p = 0.5), compared to HIC. Conclusion: Resections in LMIC were independently associated with higher 90-day postoperative mortality, likely reflecting a failure to rescue of these patients following esophagectomy, despite similar composite anastomotic leaks and major complication rates to HIC. These findings warrant further research, to identify potential issues and solutions to improve global outcomes following esophagectomy for cancer.

Abstract

Background: The complexity of oesophageal surgery and the significant risk of morbidity necessitates that oesophagectomy is predominantly performed by a consultant surgeon, or a senior trainee under their supervision. The aim of this study was to determine the impact of trainee involvement in oesophagectomy on postoperative outcomes in an international multicentre setting. Methods: Data from the multicentre Oesophago-Gastric Anastomosis Study Group (OGAA) cohort study were analysed, which comprised prospectively collected data from patients undergoing oesophagectomy for oesophageal cancer between April 2018 and December 2018. Procedures were grouped by the level of trainee involvement, and univariable and multivariable analyses were performed to compare patient outcomes across groups. Results: Of 2232 oesophagectomies from 137 centres in 41 countries, trainees were involved in 29.1 per cent of them (n = 650), performing only the abdominal phase in 230, only the chest and/or neck phases in 130, and all phases in 315 procedures. For procedures with a chest anastomosis, those with trainee involvement had similar 90-day mortality, complication and reoperation rates to consultant-performed oesophagectomies (P = 0.451, P = 0.318, and P = 0.382, respectively), while anastomotic leak rates were significantly lower in the trainee groups (P = 0.030). Procedures with a neck anastomosis had equivalent complication, anastomotic leak, and reoperation rates (P = 0.150, P = 0.430, and P = 0.632, respectively) in trainee-involved versus consultant-performed oesophagectomies, with significantly lower 90-day mortality in the trainee groups (P = 0.005). Conclusions: Trainee involvement was not found to be associated with significantly inferior postoperative outcomes for selected patients undergoing oesophagectomy. The results support continued supervised trainee involvement in oesophageal cancer surgery.

Abstract

Introduction: eSports is a recent phenomenon that has been garnering interest, mostly among young people. At first, electronic games (which today make up eSports) were considered simply a game, a pastime close to the concept of leisure. Given the dizzying growth of this industry and the emergence of championships with a significant audience, however, eSports began to be related to Sports, besides the possible 'sporting' processes present therein. Currently, eSport comprises a set of activities in which people participate, train and develop mental and physical skills through information or communication technologies. Despite this, the impacts of this phenomenon are little explored by scientific literature. Objective: This study seeks to develop a co-word analysis of the eSports research field to highlight the topics addressed in the 21st century. Methods: This bibliometric research analyzed 246 articles retrieved from the Web of Science (Thomson Reuters, New York, USA) database. Letters, editorials, book reviews, conference abstracts/papers, and news were excluded. Discovery and analysis of the main research topics in eSports was performed using the SciMAT software tool. Results & Discussion: Since eSports is a recent phenomenon, the field covers several research topics such as sport, video-game, play, game, motivations and gambling. Academic interest and publications on eSports increased significantly only since 2016, with a significant number of studies within humanities. Conclusion: Despite the few studies, eSports is not just a research topic, but an area of knowledge that encompasses several themes from different areas. In fact, it is a modern human phenomenon that uses information or communication technologies. [ABSTRACT FROM AUTHOR]

High-throughput transcriptomics reveals the mechanisms of nanopesticides – nanoformulation, commercial formulation, active ingredient – finding safe and sustainable-by-design (SSbD) options for the environmentElectronic supplementary information (ESI) available.

Abstract

Nanoformulations are developed to offer controlled release of active ingredients (a.i.) and thus aim to keep functionality while having a smaller environmental footprint. This means that nanoformulations aim to comply with the safe and sustainable by design (SSbD) concept, as a part of (re)designing to reduce their risks. However, the toxic effects of nanoformulations, particularly to non-target organisms, are poorly known, and even more so at the mechanistic level. The aim of the present study was to investigate the possible mechanisms of toxicity of atrazine when delivered as a nanoformulation of atrazine (nano_ATZ), a commercial atrazine-based formulation (Gesaprim), and the pure a.i. (ATZ). A high-throughput gene expression microarray (4 × 44 K) was used to assess transcriptomics in Enchytraeus crypticus(non-target species). Organisms were exposed, in soil, to equitoxic reproduction effect concentrations (EC10 and EC50) for 3 and 7 days. Results showed activation of genes involved in both general and well-known mechanisms of detoxification (e.g.cytochrome P450 and GST) for all the atrazine forms. Unique effects of nano_ATZ on transcripts linked to secretion, translocation and vesicle trafficking suggested that differentiated – nano-specific – uptake and/or cellular transport might be taking place. This study on the transcriptomics of a nanoformulation, the first so far, suggested differentiated mechanisms of toxicity among the nanoformulation, the a.i. and the conventional pesticides, shedding light on the issues of safe and sustainable-by-design (SSbD) for the agrochemical industry.

Abstract

Treatment of carbapenemase‐producing Enterobacteralesbloodstream infections in solid organ transplant recipients is challenging. The objective of this study was to develop a specific score to predict mortality in solid organ transplant recipients with carbapenemase‐producing Enterobacteralesbloodstream infections. A multinational, retrospective (2004‐2016) cohort study (INCREMENT‐SOT, ClinicalTrials.gov NCT02852902) was performed. The main outcome variable was 30‐day all‐cause mortality. The INCREMENT‐SOT‐CPE score was developed using logistic regression. The global cohort included 216 patients. The final logistic regression model included the following variables: INCREMENT‐CPE mortality score ≥8 (8 points), no source control (3 points), inappropriate empirical therapy (2 points), cytomegalovirus disease (7 points), lymphopenia (4 points), and the interaction between INCREMENT‐CPE score ≥8 and CMV disease (minus 7 points). This score showed an area under the receiver operating characteristic curve of 0.82 (95% confidence interval [CI] 0.76‐0.88) and classified patients into 3 strata: 0‐7 (low mortality), 8‐11 (high mortality), and 12‐17 (very‐high mortality). We performed a stratified analysis of the effect of monotherapy vs combination therapy among 165 patients who received appropriate therapy. Monotherapy was associated with higher mortality only in the very‐high (adjusted hazard ratio [HR] 2.82, 95% CI 1.13‐7.06, P= .03) and high (HR 9.93, 95% CI 2.08‐47.40, P= .004) mortality risk strata. A score‐based algorithm is provided for therapy guidance. The authors develop a predictive risk score for a solid organ transplant recipient's for mortality in patients with bloodstream infections due to carbapenemase‐producing Enterobacterales, which is useful to differentiate patients who can be treated with antimicrobial monotherapy from those who should receive combination therapy.

32. Silver catalytic effect on flash sintering of ceramics

Lavagnini, Isabela R., Yoon, Bola, Avila, Viviana, Ghose, Sanjit K., Raj, Rishi, Pallone, Eliria M.J.A., Jesus, Lílian M., and Campos, João V.

Abstract

We investigated the use of metallic silver as a catalyst for flash sintering on hydroxyapatite/zirconia (HZ) composites. Adding 3 wt.% of silver to the ceramic powder reduced the flash onset temperature (from 1084 °C to 925 °C) and also the electric field (from 300 V.cm−1to 150 V.cm−1) used in the process. We attribute this behaviour to the formation of a silver percolation path that acts as a heat source, accelerating the thermal runaway. As a result, both the flash temperature and the required electric field were reduced. Furthermore, the results suggest that the temperatures along the percolation paths are high enough to reach the boiling point of silver, forming a gaseous phase that leaves the sample.

Abstract

The use of nanotechnology in the agrochemical sector aims to increase pesticide efficiency, and at the same time provide more targeted delivery, reducing the application volume and thus its environmental footprint. However, the possible risks of these new nanopesticides to non-target organisms are still sparsely investigated. The aim of the present study was to investigate the effects of a nanoformulation of atrazine (nano_ATZ) to non-target soil invertebrates. The effect was compared with the commercial formulation (Gesaprim®) and atrazine (the pure active ingredient, a.i.), using the a.i. in a field concentration range using the soil invertebrate, Enchytraeus crypticus(Oligochaeta) as the non-target organisms. The endpoints evaluated included avoidance behaviour (2d), hatching success (11d), survival and reproduction (based on both the standard enchytraeid reproduction test (28d) and on the full life cycle test (46d)). Results showed that enchytraeids avoided soil spiked with Gesaprim and atrazine (a.i.), but not nano_ATZ. While all tested atrazine forms affected the hatching success (11d, early development stage), the toxicity in later stages, as measured in terms of survival and reproduction (46d) showed that Gesaprim was the least toxic (EC10 ca.200 mg kg−1), followed by nano_ATZ (EC10 ca.180 mg kg−1) and atrazine (a.i.) (EC10 ca.100 mg kg−1). These findings are important to nanopesticide regulatory purposes, showing the potential effects of nanoformulation compared to the current commercial non-nano ATZ in a.i. field concentrations, and that information on additional test species and exposure routes are missing, as well as the longer term consequences.

Abstract

Objective To determine the immediate effects of transcutaneous electrical nerve stimulation (TENS) on heart rate, systolic blood pressure (SBP), and diastolic blood pressure (DBP) in apparently healthy adults (age ≥18y). Data Sources The Cochrane Library (online version 2014), PubMed (1962–2014), EMBASE (1980–2014), and LILACS (1980–2014) electronic databases were searched. Study Selection Randomized controlled trials were included when TENS was administered noninvasively with surface electrodes during rest, and the effect of TENS was compared with that of control or placebo TENS. A sensitive search strategy for identifying randomized controlled trials was used by 2 independent reviewers. The initial search led to the identification of 432 studies, of which 5 articles met the eligibility criteria. Data Extraction Two independent reviewers extracted data from the selected studies. Quality was evaluated using the PEDro scale. Mean differences or standardized mean differences in outcomes were calculated. Data Synthesis Five eligible articles involved a total of 142 apparently healthy individuals. Four studies used high-frequency TENS and 3 used low-frequency TENS and evaluated the effect on SBP. Three studies using high-frequency TENS and 2 using low-frequency TENS evaluated the effect on DBP. Three studies using high-frequency TENS and 1 study using low-frequency TENS evaluated the effect on heart rate. A statistically significant reduction in SBP (−3.00mmHg; 95% confidence interval [CI], −5.02 to −0.98; P =.004) was found using low-frequency TENS. A statistically significant reduction in DBP (−1.04mmHg; 95% CI, −2.77 to −0.03; I 2 =61%; P =.04) and in heart rate (−2.55beats/min; 95% CI, −4.31 to −0.78; I 2 =86%; P =.005]) was found using both frequencies. The median value on the PEDro scale was 7 (range, 4–8). Conclusions TENS seems to promote a discrete reduction in SBP, DBP, and heart rate in apparently healthy individuals. [ABSTRACT FROM AUTHOR]

Abstract

OBJECTIVE: The mismatch repair (MMR) genes play a central role for the onset of cancer. One of these genes is hMSH2. A differential hMSH2 protein expression has been detected in the mononuclear fraction of peripheral blood of patients with breast cancer when compared to healthy women. This work aims to evaluate the expression of hMSH2 in patients diagnosed with breast cancer undergoing treatment at various stages of the disease to verify its potential use as a prognostic marker. PATIENTS AND METHODS: Immunohistochemical expression of hMSH2 at different stages of breast cancer in 40 patients biopsy samples were analyzed. RESULTS: hMSH2 has a considerable increased expression in all groups of patients with tumors, when compared to patients without tumors. CONCLUSIONS: immunohistochemistry indeed can be a great tool for the diagnosis of breast cancer, as it is an easy and versatile technique. [ABSTRACT FROM AUTHOR]

Abstract

OBJECTIVE: The acute lymphocytic leukemia is a hematopoietic cancer that occurs predominantly in children. Methotrexate is one of the most useful drugs in cancer chemotherapy. The aim of the study was to develop and validate the methodology of high performance liquid chromatography (HPLC) with ultraviolet detection for methotrexate dosage and to determine its concentration in plasma samples from children with leukemia. PATIENTS AND METHODS: The study included patients from the outpatient care of pediatric oncology at the Faculty of Medicine of ABC carriers in treatment of leukemia. The study was conducted in chromatographic model Agilent 1100 with UV detector at 302 nm and by the method of ELISA microplate reader capable of reading absorbance at 450 nm. RESULTS: We obtained satisfactory results of selectivity, accuracy, linearity, limit of quantification (LOQ), limit of detection (LOD), precision and robustness and apply the basic criteria for validation as RE No. 899, of May 29, 2003 Guide validation of analytical and bioanalytical National Agency Health Surveillance (ANVISA). CONCLUSIONS: We conclude that results for linearity/concentration range, precision, robustness, limit of quantification and detection limits are within the acceptance criteria defined by ANVISA and that the developed analytical method is valid and feasible to be used as a tool in monitoring therapy of methotrexate.

39. RTEL1 and MCM10 overcome topological stress during vertebrate replication termination

Abstract

Topological stress can cause converging replication forks to stall during termination of vertebrate DNA synthesis. However, replication forks ultimately overcome fork stalling, suggesting that alternative mechanisms of termination exist. Using proteomics in Xenopusegg extracts, we show that the helicase RTEL1 and the replisome protein MCM10 are highly enriched on chromatin during fork convergence and are crucially important for fork convergence under conditions of topological stress. RTEL1 and MCM10 cooperate to promote fork convergence and do not impact topoisomerase activity but do promote fork progression through a replication barrier. Thus, RTEL1 and MCM10 play a general role in promoting progression of stalled forks, including when forks stall during termination. Our data reveal an alternate mechanism of termination involving RTEL1 and MCM10 that can be used to complete DNA synthesis under conditions of topological stress.

Camargo, Priscila C.L.B., Pato, Eduardo Z.S., Campos, Silvia V., Afonso, José E., Carraro, Rafael M., Costa, André N., Teixeira, Ricardo H.O.B., Samano, Marcos N., and Pêgo-Fernandes, Paulo M.

Abstract

Lung transplantation is a well-established treatment for advanced lung diseases. In children, the diseases that most commonly lead to the need for a transplantation are cystic fibrosis, pulmonary hypertension, and bronchiolitis. However, the number of pediatric lung transplantations being performed is low compared with the number of transplants performed in the adult age group. The objective of this study was to demonstrate our experience with pediatric lung transplants over a 10-year period in a program initially designed for adults.

Abstract

Gestational depression is detrimental to the health of the mother and the offspring and contributes to the appearance of depressive and anxiety symptoms during the postnatal period. Traditional antidepressants have undesirable side effects when utilised during gestation, but Hypericum perforatumhas been characterised as an efficient and safe antidepressant that prevents the recurrence of symptoms. This study verified the effects of Hypericum perforatumon the behaviour of Wistar rats that were treated during gestation and evaluated 10 and 60 days post-treatment. Pregnant Wistar rats were divided into four groups of ten animals each: one control group that received distilled water and three treatment groups that were treated orally with 36, 72 or 144mg/kg Hypericum perforatumextract. At 10 and 60 days after parturition and post-treatment, the rats were submitted to the holeboard, the tail suspension, and the forced swim tests. The animals treated with 144mg/ kg Hypericum perforatumexhibited greater head-dipping activity in the hole-board test and reduced immobility in the tail suspension and forced swim tests, suggesting less anxiety and depression 10 and 60 days post-treatment. The results indicated that treating rats with Hypericum perforatumduring the gestational period decreased depressive behaviour and anxiety 10 and 60 days post-treatment.

47. Influence of grease formulation on thrust bearings power loss

Author

Cousseau, T, Graça, B M, Campos, A V, and Seabra, J H O

Abstract

The minimization of the power loss and the use of the biodegradable greases have attracting considerable attention. To compare the energetic performance of biodegradable lubricant greases, power loss tests were performed on a modified four-ball machine. A correlation between the grease formulation and rheology was established with its energetic performance.

48. A Naked Eye‐Invisible Ratiometric Fluorescent Microneedle Tattoo for Real‐Time Monitoring of Inflammatory Skin Conditions

Author

Abstract

The field of portable healthcare monitoring devices has an urgent need for the development of real‐time, noninvasive sensing and detection methods for various physiological analytes. Currently, transdermal sensing techniques are severely limited in scope (i.e., measurement of heart rate or sweat composition), or else tend to be invasive, often needing to be performed in a clinical setting. This study proposes a minimally invasive alternative strategy, consisting of using dissolving polymeric microneedles to deliver naked eye‐invisible functional fluorescent ratiometric microneedle tattoos directly to the skin for real‐time monitoring and quantification of physiological and pathological parameters. Reactive oxygen species are overexpressed in the skin in association with various pathological conditions. Here, one demonstrates for the first time the microneedle‐based delivery to the skin of active fluorescent sensors in the form of an invisible, ratiometric microneedle tattoo capable of sensing reactive oxygen species in a reconstructed human‐based skin disease model, as well as an in vivo model of UV‐induced dermal inflammation. One also elaborates a universal ratiometric quantification concept coupled with a custom‐built, multiwavelength portable fluorescence detection system. Fully realized, this approach presents an opportunity for the minimally invasive monitoring of a broad range of physiological parameters through the skin. Dissolving polymeric microneedles can deliver a transient functional fluorescent microneedle tattoo capable of generating a ratiometric response to physiological parameters. This can be applied to the monitoring of reactive oxygen species in the context of inflammatory skin diseases. This is demonstrated in a reconstructed human‐based skin disease model and an in vivo model of UV‐related dermal inflammation.
