Background: Helicobacter pylori detection in asymptomatic children with suspected infection or with symptoms that suggest gastric pathology is problematic, since most of the methods depend on the endoscopic study, an invasive and expensive method. Non-invasive methods can be a feasible alternative but must be validated. The purpose of this study was to evaluate the concordance between H. pylori DNA detection in saliva and dental plaque by PCR, with antigen detection in stool by immunochromatography, among asymptomatic children in the state of Guerrero, Mexico., Methods: Dental plaque, saliva, and stool samples were obtained from 171 children between 6 and 12 years old. H. pylori detection in saliva and dental plaque was performed by PCR using specific primers for the 16S rRNA gene, while the detection in stool samples was performed by immunochromatography using the CerTest kit., Results: We found an overall H. pylori prevalence of 59.6% (102/171). Of the H. pylori positive children 18% (20/111) were positive in saliva samples, 28.1% (34/121) in dental plaque samples, and 50.4% (71/141) in stool samples. A higher prevalence was found in girls (64.7%, p = 0.002). Although some of the children declared some dyspeptic symptoms, these were no related to H. pylori . In conclusion, we found a high prevalence of H. pylori in asymptomatic children and the highest proportion was detected by stool antigen test, which was the most feasible method to detect H. pylori infection., Competing Interests: The authors declare that they have no competing interests., (© 2021 Martínez-Santos et al.)

Introduction: Catheter-based renal sympathetic denervation is an emerging therapy for resistant hypertension (RHTN) patients, resulting in a significant blood pressure reduction. The presence of accessory renal arteries and anomalous branching patterns are reported in approximately 20-27 % of patients. However, accessory renal arteries, when smaller than 4 mm in diameter, they are out of the inclusion criteria for renal denervation therapy. For this reason patients with evidence of accessory renal arteries have been excluded in previous clinical trials. Recent data suggest that accessory renal arteries may play an important role in non-response therapy when they do not receive renal denervation treatment., Case Report: In this report, we present the outcome of a patient with resistant hypertension and an anomalous right renal artery, having undergone denervation of both principal and accessory renal arteries. The renal ablation by radiofrequency energy of a distant accessory renal artery resulted in a safe procedure with no clinical complications., Conclusion: Consistent with literature the RDN of all, main and accessory renal arteries, was effective in decreasing patient blood pressure while decreasing the need for antihypertensive medication.

In the sixteenth century, a partial Spanish translation of Boccaccio's Filocolo was published with a double title: Laberinto de amor and Trece cuestiones muy graciosas. This change has to do with an interesting editorial plot, since the translation was published first in Seville (1541) "a hurtadas" (on the sly) and then in Toledo (1546), in an edition authorized by its translator. The complete collation of both editions reveals, on the one hand, that the Sevillian printer made all kinds of imbalances in the translation prepared by López de Ayala to adjust the account of the original to the mold; on the other hand, some variants show that the translator again revised his translation in the new edition of the Trece cuestiones muy graciosas, published in the same press 3 years later.

The periodical press of the teaching profession experienced a special boom in the last quarter of the 19th century, a time when publications multiplied and the teaching press became more professional, thus becoming a privileged channel for the dissemination of ideas and pedagogical and linguistic knowledge. In this paper we are interested in analysing together two fundamental ways of channelling grammatical thought in the nineteenth century: that of the professional teaching press (the media way) and that of the grammatical treatises signed by the same authors who wrote in the different newspapers of the field (the textbooks way). Specifically, we will delve into one of the many grammatical controversies that took place on the pages of the written press during the 19th century (and which has recently been dealt with by Gaviño Rodríguez 2021a): the debate on the nature of possessives (initiated in September 1873 and ended in April 1874) in order to: (i) compare the different arguments used with the doctrine defended by the debaters in their respective grammar books; (ii) verify the feedback of these two main ways of channelling grammatical thought; (iii) check the effectiveness of the press as a channel for debate and linguistic reflection, as well as a means of ongoing teacher training.

In the first few decades of the twentieth century, makeshift shelters known as chozas grew in Madrid. Using historical monographs and the press as main sources, in this article we discuss the influence of medical thinking on the problematisation and eradication of this form of urban growth. During the nineteenth century, scientific racism identified poor housing areas as a source of disease and immorality, yet the public powers in Madrid tolerated and overlooked the development of these spaces until the early twentieth century. It was only when the fear of epidemics and warnings from the press became too great that the authorities began to implement various high-profile 'sanitary campaigns' to destroy the shacks. Although these initiatives did not solve the sanitation problems because the deprived populations frequently constructed new living areas, the continued efforts of the public authorities succeeded in displacing the shantytowns to the less regulated periphery. Whilst the spaces were transformed, the representations that signalled them as pathological spaces seems to have remained. Research on the historical eradication of urban 'otherness' allows us to discuss the legacy of the medical theories that supported it and the influence of this on current prejudices regarding disadvantaged neighbourhoods.

THE ABILITY TO PERCEIVE AND PRODUCE A BEAT IS believed to be universal in humans, but individual ability varies. The current study examined four factors that may influence beat perception and production capacity: 1) expertise: music or dance, 2) training style: percussive or nonpercussive, 3) stimulus modality: auditory or visual, and 4) movement type: finger-tap or whole-body bounce. Experiment 1 examined how expertise and training style influenced beat perception and production performance using an auditory beat perception task and a finger-tapping beat production task. Experiment 2 used a similar sample with an audiovisual variant of the beat perception task, and a standing knee-bend (bounce) beat production task to assess whole-body movement. The data showed that: 1) musicians were more accurate in a finger-tapping beat synchronization task compared to dancers and controls, 2) training style did not significantly influence beat perception and production, 3) visual beat information did not benefit any group, and 4) beat synchronization in a full-body movement task was comparable for musicians and dancers; both groups outperformed controls. The current study suggests that the type of task and measured response interacts with expertise, and that expertise effects may be masked by selection of nonoptimal response types.

Electrodes fabricated on a flexible substrate are a revolutionary development in wearable health monitoring due to their lightweight, breathability, comfort, and flexibility to conform to the curvilinear body shape. Different metallic thin-film and plastic-based substrates lack comfort for long-term monitoring applications. However, the insulating nature of different polymer, fiber, and textile substrates requires the deposition of conductive materials to render interactive functionality to substrates. Besides, the high porosity and flexibility of fiber and textile substrates pose a great challenge for the homogenous deposition of active materials. Printing is an excellent process to produce a flexible conductive textile electrode for wearable health monitoring applications due to its low cost and scalability. This article critically reviews the current state of the art of different textile architectures as a substrate for the deposition of conductive nanomaterials. Furthermore, recent progress in various printing processes of nanomaterials, challenges of printing nanomaterials on textiles, and their health monitoring applications are described systematically.

Foliar disease is common problem in plants; it appears as an abnormal change in the plant's characteristics, such as the presence of lesions and discolorations, among others. These problems may be related to plant growth, which causes a decrease in crop production, impacting the agricultural economy. The causes of leaf damage can be variable, such as bacteria, viruses, nutritional deficiencies, or even consequences of climate change. Motivated to find a solution for this problem, we aim that using image processing and machine learning algorithms (MLA), these symptomatic characteristics of the leaf can be used to classify diseases. Then, contributions of this research are (i) the use of image processing methods in the feature extraction (characteristics), and (ii) the combination of assembled algorithms with deep learning to classify foliar features of Valencia orange (Citrus Sinensis) tree leaves. Combining these two classification approaches, we get optimal rates in binary datasets and highly competitive percentages in multiclass sets. This, using a database of images of three types of foliar damage of local plants. Result of combination of these two classification strategies is an exceptional reliable alternative for leaf damage identification of orange and other citrus plants. [ABSTRACT FROM AUTHOR]
