An integrated textile electronic system is reported here, enabling a truly free form factor system via textile manufacturing integration of fiber-based electronic components. Intelligent and smart ...systems require freedom of form factor, unrestricted design, and unlimited scale. Initial attempts to develop conductive fibers and textile electronics failed to achieve reliable integration and performance required for industrial-scale manufacturing of technical textiles by standard weaving technologies. Here, we present a textile electronic system with functional one-dimensional devices, including fiber photodetectors (as an input device), fiber supercapacitors (as an energy storage device), fiber field-effect transistors (as an electronic driving device), and fiber quantum dot light-emitting diodes (as an output device). As a proof of concept applicable to smart homes, a textile electronic system composed of multiple functional fiber components is demonstrated, enabling luminance modulation and letter indication depending on sunlight intensity.
Smart textiles consist of discrete devices fabricated from-or incorporated onto-fibres. Despite the tremendous progress in smart textiles for lighting/display applications, a large scale approach for ...a smart display system with integrated multifunctional devices in traditional textile platforms has yet to be demonstrated. Here we report the realisation of a fully operational 46-inch smart textile lighting/display system consisting of RGB fibrous LEDs coupled with multifunctional fibre devices that are capable of wireless power transmission, touch sensing, photodetection, environmental/biosignal monitoring, and energy storage. The smart textile display system exhibits full freedom of form factors, including flexibility, bendability, and rollability as a vivid RGB lighting/grey-level-controlled full colour display apparatus with embedded fibre devices that are configured to provide external stimuli detection. Our systematic design and integration strategies are transformational and provide the foundation for realising highly functional smart lighting/display textiles over large area for revolutionary applications on smart homes and internet of things (IoT).
Immune signatures at birth could be associated with clinical outcomes and will improve our understanding of immunity prenatal programming.
Data come from 235 newborns from the cohort study NELA. ...Production of cytokines was determined using Luminex technology. Associations between cytokine concentrations with sex and season of birth were examined by multivariate regression models.
Umbilical cord blood cells produced high levels of inflammatory cytokines, moderate levels of Th1/Th2/Tr-related cytokines, and low levels of Th17 cytokines. Compared to females, male newborn cells secreted higher levels of Th2 (peptidoglycan-stimulated IL-13, odds ratio OR = 2.26; 95% CI 1.18, 4.31, p value = 0.013) and Th17 (polyinosinic:polycytidylic acid-stimulated IL-23, OR = 1.82, 95% CI 1.01, 3.27, p value = 0.046) and lower levels of Th1 (olive-stimulated IL-2, OR = 0.56, 95% CI 0.31, 0.99, p value = 0.047) cytokines. Also, children born during warm seasons showed decreased innate cytokine response to peptidoglycan (IL-6, OR = 0.28, 95% CI 0.15, 0.52, p value < 0.001) compared to those born in cold seasons; meanwhile, adaptive immunity cytokines were more frequently secreted by children born during warm seasons in response to allergen extracts (IL-10, OR = 2.11, 95% CI 1.12, 3.96, p value = 0.020; IL-17F, OR = 3.31, 95% CI 1.83, 5.99, p value < 0.001).
Newborns showed specific cytokines signatures influenced by sex and season of birth.
There is a limited number of population-based studies on the immune status at birth and the influence of prenatal and perinatal factors on it. Characterization of cytokine signatures at birth related to the prenatal environment could improve our understanding of immunity prenatal programming. Newborns exhibit specific unstimulated and stimulated cytokine signatures influenced by sex and season of birth. Unstimulated and stimulated cytokine signatures in newborns may be associated with the development of related clinical outcomes later in life.
Background Myxomas are rare cardiac tumors which often present with stroke caused by tumorous or thrombotic emboli. Treatment with intravenous recombinant tissue plasminogen activator (rtPA) and ...intra-arterial thrombolysis has been described previously but mechanical thrombectomy has not yet been reported, and treatment of myxoma-related ischemic stroke remains a clinical and technical challenge. Methods Two patients with ischemic stroke due to cardiac myxoma in which mechanical thrombectomy was performed are presented. Results Endovascular thrombectomy after intravenous rtPA (bridging therapy) was safely achieved in both cases, although with different clinical outcomes and degrees of recanalization. Conclusions In stroke secondary to cardiac myxoma, mechanical thrombectomy might represent a safe and effective treatment option. The authors suggest the use of histological examination of the clot for diagnosis as its composition may explain the differences in treatment outcome.
Objective
Design a risk model to predict bacteraemia in patients attended in emergency departments (ED) for an episode of infection.
Methods
This was a national, prospective, multicentre, ...observational cohort study of blood cultures (BC) collected from adult patients (≥ 18 years) attended in 71 Spanish EDs from October 1 2019 to March 31, 2020. Variables with a
p
value < 0.05 were introduced in the univariate analysis together with those of clinical significance. The final selection of variables for the scoring scale was made by logistic regression with selection by introduction. The results obtained were internally validated by dividing the sample in a derivation and a validation cohort.
Results
A total of 4,439 infectious episodes were included. Of these, 899 (20.25%) were considered as true bacteraemia. A predictive model for bacteraemia was defined with seven variables according to the Bacteraemia Prediction Model of the INFURG-SEMES group (MPB-INFURG-SEMES). The model achieved an area under the curve-receiver operating curve of 0.924 (CI 95%:0.914–0.934) in the derivation cohort, and 0.926 (CI 95%: 0.910–0.942) in the validation cohort. Patients were then split into ten risk categories, and had the following rates of risk: 0.2%(0 points), 0.4%(1 point), 0.9%(2 points), 1.8%(3 points), 4.7%(4 points), 19.1% (5 points), 39.1% (6 points), 56.8% (7 points), 71.1% (8 points), 82.7% (9 points) and 90.1% (10 points). Findings were similar in the validation cohort. The cut-off point of five points provided the best precision with a sensitivity of 95.94%, specificity of 76.28%, positive predictive value of 53.63% and negative predictive value of 98.50%.
Conclusion
The MPB-INFURG-SEMES model may be useful for the stratification of risk of bacteraemia in adult patients with infection in EDs, together with clinical judgement and other variables independent of the process and the patient.
To analyze the incidence of Covid-19 in patients who are chronic users of hydroxychloroquine.
Cross-sectional retrospective observational multicenter study in health areas and districts from Castilla ...La-Mancha and Andalucia. Of the 4451 participants included in the first recruitment, 3817 with valid data were selected. The main variable of the study is the presence or absence of Covid-19 infection by clinical, serological or polymerase chain reaction diagnosis. Sociodemographic and clinical variables and treatment and concomitant comorbidities were recorded.
169 (4,45%) patients had Covid-19 infection, of which 12 (7.1%) died and 32 (18.9%) required hospital admission. Previous respiratory pathology was related to Covid-19 infection (P<.05). Maculopathy appears in 5.3% of patients and is significantly related to the dose of hydroxychloroquine consumed (P<.05).
There is no relationship between chronic use of hydroxychloroquine and the incidence of Covid-19.
To develop a set of recommendations, by consensus of Emergency Medicine experts, on key aspects related to the care of adult patients with acute infection attended in Spanish emergency departments ...(ED).
The study was divided into three phases: 1) To design a questionnaire by a coordinating group; 2) To conduct a survey in ED physicians in order to know their opinion on the issues raised by the coordinating group; 3) To develop a number of recommendations based on the responses to the questionnaire and their subsequent discussion.
A group of 28 experts from different Spanish ED, as well as 5 members of the coordinating group, with knowledge and experience in the management of infectious diseases in ED, conducted a round of voting to a questionnaire of 18 issues grouped into three sections: 1) identification and stratification of the severity; 2) diagnosis and treatment; 3) management.
A monitoring system and proper training of the entire healthcare team are required, as well as extensive knowledge on these issues, to ensure adequate and effective care for these patients. It is essential to educate and train all health staff, especially in the ED, because it is the initial point of contact for most patients with an infection. The experts established proposals based on survey questions and the discussion.
