Published: July 2021

Introduction Introduction: The Antisynthetase Syndrome is a rare entity that is included within the idiopathic inflammatory myopathies, characterized by the presence of antisynthetase antibodies, they can be found in 39.1% of the patients with these myopathies. The affectation is systemic being the main ones at the articular level in 40% -80%. Lung damage occurs in 60% -80%, the most frequent findings being ground glass, predominantly crosslinking in lower segments, probably with a pattern of non-specific interstitial pneumonia, organized pneumonia, or mixed patterns. Regarding muscle involvement, it occurs in 60% -80%. Treatment is based on the use of corticosteroids, immunosuppressants, and biological agents. Case description A 38-year-old female patient with no significant clinical or family history was approached, single (no children), who presented gradual and intermittent joint pain and muscle weakness associated with progressive dyspnea, in the context of The current pandemic was swabbed for SARS-COV-2 on two occasions as well as antibodies for the same virus being negative, with tomographic findings compatible with an alternative pattern, despite the aforementioned, it was treated in a particular way with a scheme directed towards COVID -19, with partial resolution of the symptoms and subsequent exacerbation of the same, for which he went to hospital care, where the swab was repeated obtaining negativity of the same, deciding on this occasion an evaluation by the Pneumology Service and hospitalization. During his stay, an immunological panel was performed where a weak elevation of rheumatoid factor is evidenced, due to logistical issues Myositis panel we are waiting, however, due to the lack of specific etiology, it was decided to perform a lung biopsy reporting a concordant pattern of organized pneumonia With the tomographic diagnosis, the evolution of the patient was favorable with supportive treatment until the results of the external immunological panel were received, evidencing a marked elevation of the anti-Jo antibody, added to the clinical and image manifestations, the picture is cataloged as an Antisynthetase Syndrome. Thus, with the support of rheumatology, treatment with corticosteroids (methylprednisolone), immunosuppressants (mycophenolate) and biological agent (rituximab) is started; with which there was significant clinical improvement, decrease in o2 support as well as lung lesions, with which we proceeded to discharge with the respective follow-up by the services involved. Conclusions: As we evidenced in the clinical case, in a retrospective way, we can assert that it complied with the clinical manifestations of the disease, although we are experiencing a pandemic where lung involvement is important, once it has been ruled out, other diagnostic possibilities must be addressed. As in the patient, it culminated in the presentation of a rheumatological picture with lung damage.

Introduction Takotsubo Syndrome (STk) is characterized by a transient systolic regional dysfunction on the left ventricle, usually diagnosed in 2% of the patients presenting with clinical suspicion of ST elevating myocardial infarction (STAMI). Main etiology is still unclear, correlating with pericardial artery spasm, microvascular alterations, viral myocarditis, heightened catecholamine levels with alteration of sympathetic system, and anatomical variations of the anterior descendent artery. Several emotional and physical triggers are linked to its development, but symptoms can arise in their absence. Most common signs and symptoms include: acute chest pain, dyspnea and syncope, initially indistinct to those of an acute myocardial infarction. Its presence varies according to the trigger: on those with a strong emotional trigger chest pain and palpitations, while on physical stress, underlying disease predominates (stroke, seizure). Case description A 58 year old female, without medical history of cardiovascular disease, was admitted to the hospital because of left sided chest pain, beginning 2 hours ago, most likely caused by emotional distress. On arrival, initial diagnosis was Acute Coronary Disorder (ACD). Coronarography, and anterior oblique right ventriculography confirming the diagnosis. Requiring mainly low-molecular-weight heparin anticoagulation during admission and novel anticoagulants for outpatient care, added to anxiety treatment. Follow-up started October 2019 and went on during 2020. Conclusion STk has similar characteristics to those of ACD on postmenopausal women. The present Clinical Case meets 3 of the 4 Mayo Criteria, and has 61 points on the InterTak score. Acute chest pain, dyspnea and syncope plus several additional studies can confirm STk. EKG showing ST elevation (90%), negative T wave on precordial leads (44%), Q wave present (15-27%). Elevation of the ST segment on V4 to V6 is higher than V1 to V3, with absence of Q anomaly. Heightened troponin levels, but lower than AMI; Heghtened BPN or proBPN could be present. Myocardial stunning could be liked to catecholamine levels 2 to 3 times higher than AMI with Killip III. The recovery does not require treatment, but could require diuretics, beta blockers, ACEs, angiotensin-II receptor blockers, statins and acetylsalicylic acid. Prognosis is favorable with mortality under the 2%.

Published: July 2021

Platelets are essential elements of human blood. In addition to their normal role, platelets are involved in causing myocardial infarction, stroke and other thrombotic disorders. Platelet activation in vivo, probably involves a combination of agonists. Garlic has beneficial effects due to its ability to inhibit platelet aggregation and thromboxane formation. The aim of this work was to evaluate the ability of garlic extracts to inhibit platelet aggregation induced by different agonists and their mixtures in different donors. Significant differences were found in platelet aggregation in response to each agonist (P â‰¤ 0.05). The highest antiaggregatory effect was observed with arachidonic acid and the lowest effect with collagen-arachidonic acid mixture. Interaction effects between donor and agonist (or mixtures) were detected. The study showed the potential of aqueous garlic extracts to prevent platelet aggregation induced by different agonist.

Highlights

Platelets play a central role in the progression of atherosclerotic lesions.

Blood from nine non-smoker healthy donors was used for in vitro platelet aggregation study.

Significant differences were found in platelet aggregation in response to each agonist.

Aqueous garlic extracts could prevent platelet aggregation induced by different agonist.

Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. You have probably heard of Blockchain in the past few years, mostly in the context of crypto currency. However, Blockchain has grown to have several different applications. The significant part about Blockchain is that it is never under the complete control of a single entity due to being entirely consensus-driven. It can never change the data you store in the Blockchain used widely in sharing medical data in the healthcare industry. Due to the security that Blockchain provides, this data can be shared among parties seamlessly. Another application of Blockchain is in maintaining the integrity of payment systems. Blockchain-based payment systems are immune to external attacks and theft. Blockchain can also be used in tracking the status of products in a supply chain in real-time.

Quorum sensing related activity of Aggregatibacter actinomycetemcomitans in periodontal disease: A review
Authors: Nurhayati Abdullah Haswati , Mohamad Suharni , WanTaib Wan Rohani , Jaffar Norzawani
Published: July 2021

Aggregatibacter actinomycetemcomitans is a significant pathogen in periodontal disease, contributing to aggressive and chronic inflammatory conditions of the periodontal area. This pathogen is shown to contribute to the tenacious biofilm formation in the oral cavity and results in persistent induction of pro-inflammatory response leads to progressive periodontitis. Besides the immune-modulatory capabilities, quorum sensing (QS) activity is believed to influence the virulence activities, leading to a progressive inflammatory response by the host. QS modulates the expression of genes involved in the processes related to survival and biofilm formation activities by answering the localized bacterial population's fluctuation. Understanding the QS activity of this pathogen and its impact on disease might be useful as an alternative approach to counteract the infection. Therefore, this review paper is focusing on the evaluation of the QS activities of A. actinomycetemcomitans and how this activity influences the progression of periodontal disease. Based on the previous findings, we found that there are possibilities the QS activity interrupted by enzymes or molecules that blocking the QS signals produced by other species of bacteria. However, due to minimal QS studies that have been done specifically on A. actinomycetemcomitans, the mechanism is not conclusive. Therefore, this might initiate an essential option for alternative treatment against periodontal pathogen infection and oral health care.

Published: July 2021

Hypothetical Secure mystery express accumulating is a crucial perspective in systems considering secret expression affirmation, which is at this point the most extensively used approval method, disregarding its some security abandons. In this paper, we propose a mysterious key affirmation structure that is expected for secure mystery key storing and could be adequately organized into existing approval systems. In our construction, first, they got plain mystery word from a client is worked out a cryptographic hash work (e.g., SHA-256). By then, the hashed secret expression is changed over into a negative mystery state. Finally, the negative mystery key is encoded into an Encrypted Negative Password (contracted as ENP) using a symmetric-key computation (e.g., AES), and multi activity encryption could be used to furthermore improve security. The cryptographic hash work and symmetric encryption make it difficult to break passwords from ENPs. Furthermore, there are lots of relating ENPs for ensured plain mystery word, which makes pre-computation attacks (e.g., question table attack and rainbow table attack) infeasible. The count multifaceted nature examinations and relationships show that the ENP could go against inquiry table attack and give more grounded secret word security under word reference attack. It merits referring to that the ENP doesn't present extra segments (e.g., salt); other than this, the ENP could regardless face precomputation attacks. Most importantly, the ENP is the primary mystery state confirmation plot that joins the cryptographic hash work, the negative mystery key and the symmetric-key computation, without the necessity for additional information.

Authors: E. Elgabeery Rana , A. Eissa Radwa , M. Soliman Sohair , F. Ghoname Naglaa
Published: July 2021

Background: As Mobile Phones (MPs) aren’t cleaned routinely and have been touched
during patient’s examination, they may become contaminated with hospital pathogens.
Objectives: Screen MPs of Health care workers (HCWs) for pathogens and verify the
effect of disinfectants in their decontamination. Methods: A questionnaire was submitted
by 160 HCWs in Tanta University Hospitals. Samples were taken from their MPs and
subjected to pour plate counting before and after disinfection. Standard identification
and antibiotic susceptibility of isolates were done. Results: Colony count was greater in
MPs used while caring for patients or inside restroom, and was less in regularly cleaned
MPs. All tested disinfectants reduced the colony count significantly. Pathogens were
isolated from 84.38% of samples and 36.25% of them were Multi-Drug Resistant
Organisms (MDROs). Conclusion: Using MPs at critical care areas and restroom may
contribute to their contamination with pathogens. Regular disinfection of MPs can
reduce this contamination.

Published: July 2021

Present study was conducted to evaluate the fly ash potential as a soil amendment for growth and yield of garden pea (Pisum sativum L.). Field experiment had been designed to study in depth the application of fly ash, organic manure like farmyard manure (FYM), bio compost (SOM) and chemical fertilizer (CF) in different combinations. Arkel a pea cultivar was used in the study. The crop was raised as per appropriate agronomical practices. Different growth and yield parameters under different treatments were observed and recorded up to 90 DAS. Combined application of FA and CF with either FYM or SOM helped in improving the measured growth parameters as compared to FA alone and control. Application of organic material in conjunction with CF helped in improving nutrient supplying capacity of the soil which was further increased when FA was added as a soil amendment. Under adequate supply of nutrients, the observed growth parameters were enhanced. The positive outcome of the results of the present investigation is expected to encourage large scale use of fly ash in agriculture with an added advantage of decreasing environmental pollution; however, the changes in soil environment caused by fly ash incorporation need to be investigated on long term basis.

Published: July 2021

Abstract. New particle formation (NPF) is thought to contribute half of the global cloud condensation nuclei. A better understanding of the NPF at different
altitudes can help assess the impact of NPF on cloud formation and
corresponding physical properties. However, NPF is not sufficiently
understood in the upper mixing layer because previous studies mainly focused on ground-level measurements. In this study, the developments of aerosol
size distribution at different altitudes are characterized based on the
field measurement conducted in January 2019 in Beijing, China. We find that the partition of nucleation-mode particles in the upper mixing layer is larger than that at the ground, which implies that the nucleation processing
is more likely to happen in the upper mixing layer than that at the ground.
Results of the radiative transfer model show that the photolysis rates of
the nitrogen dioxide and ozone increase with altitude within the mixing
layer, which leads to a higher concentration of sulfuric acid in the upper mixing layer than that at the ground. Therefore, the nucleation processing
in the upper mixing layer should be stronger than that at the ground, which
is consistent with our measurement results. Our study emphasizes the
influence of aerosol–radiation interaction on the NPF. These results have the potential to improve our understanding of the source of cloud
condensation nuclei on a global scale due to the impacts of aerosol–radiation interaction.
SolveSAPHE-r2 (v2.0.1): revisiting and extending the Solver Suite for Alkalinity-PH Equations for usage with CO2, HCO3− or CO32− input data
Authors: Munhoven Guy
Published: July 2021

Abstract. The successful and efficient approach at the basis of the Solver Suite for Alkalinity-PH Equations (SolveSAPHE) (Munhoven, 2013), which determines the carbonate system speciation by calculating pH from total alkalinity (AlkT) and dissolved inorganic carbon (CT), and which converges for any physically sensible pair of such data, has been adapted and further developed to work with AlkT–CO2, AlkT–HCO3-, and AlkT–CO32-.
The mathematical properties of the three modified alkalinity–pH equations are explored.
It is shown that the AlkT–CO2, and AlkT–HCO3- problems have one and only one positive root for any physically sensible pair of data (i.e. such that [CO2]>0 and [HCO3-]>0).
The space of AlkT–CO32- pairs is partitioned into regions where there is either no solution, one solution or where there are two.
The numerical solution of the modified alkalinity–pH equations is far more demanding than that for the original AlkT–CT pair as they exhibit strong gradients and are not always monotonous.
The two main algorithms used in SolveSAPHE v1 have been revised in depth to reliably process the three additional data input pairs.
The AlkT–CO2 pair is numerically the most challenging.
With the Newton–Raphson-based solver, it takes about 5 times as long to solve as the companion AlkT–CT pair;
the AlkT–CO32- pair requires on average about 4 times as much time as the AlkT–CT pair.
All in all, the secant-based solver offers the best performance.
It outperforms the Newton–Raphson-based one by up to a factor of 4 in terms of average numbers of iterations and execution time and yet reaches equation residuals that are up to 7 orders of magnitude lower.
Just like the pH solvers from the v1 series, SolveSAPHE-r2 includes automatic root bracketing and efficient initialisation schemes for the iterative solvers. For AlkT–CO32- data pairs, it also determines the number of roots and calculates non-overlapping bracketing intervals.
An open-source reference implementation of the new algorithms in Fortran 90 is made publicly available for usage under the GNU Lesser General Public Licence version 3 (LGPLv3) or later.
Ensemble Riemannian data assimilation over the Wasserstein space

Published: July 2021

Abstract. In this paper, we present an ensemble data assimilation paradigm over a Riemannian manifold equipped with the Wasserstein metric. Unlike the Euclidean distance used in classic data assimilation methodologies, the Wasserstein metric can capture the translation and difference between the shapes of square-integrable probability distributions of the background state and observations. This enables us to formally penalize geophysical biases in state space with non-Gaussian distributions. The new approach is applied to dissipative and chaotic evolutionary dynamics, and its potential advantages and limitations are highlighted compared to the classic ensemble data assimilation approaches under systematic errors.
Infrastructure is not enough: Interactions between the environment, socioeconomic disadvantage, and cycling participation in England

Published: July 2021

Cycling can be particularly beneficial for socioeconomically disadvantaged populations. First, because it can allow them to access opportunities that by other modes they may not afford. Secondly, because it can increase their physical activity levels and, consequently, improve their health. We analyse the extent to which socioeconomic disadvantage impacts on cycling participation in England, for both leisure and utility cycling. Then, we explore the extent to which this impact could be explained by the environment in which disadvantaged populations live.  The study population includes 167,178 individuals, residing in 2,931 areas, and 326 Local Authorities. Data on individual factors were drawn from the Active Lives Survey, and data on environmental factors from several sources. Descriptive statistics and multilevel logistic models were estimated. The likelihood of cycling is lower among people living in deprived areas than among people living in non-deprived areas. This difference is significant for leisure, but also for utility cycling when controlling for individual and environmental factors. The study also found that cycling infrastructure and greater levels of cyclability are higher in deprived areas than in non-deprived areas. This suggests that infrastructure and cyclability are not enough to increase cycling levels among disadvantaged populations. Further research on other barriers to cycling among disadvantaged populations is required.
Chile COVID-19 Governmental Response

The International Health Regulations (2005) are legally binding on 196 States Parties, Including all WHO Member States. The IHR aims to keep the world informed about public health risks, through committing all signatories to cooperate together in combating any future “illness or medical condition, irrespective of origin or source, that presents or could present significant harm to humans.” Under IHR, countries agreed to strengthen their public health capacities and notify the WHO of any such illness in their populations. The WHO would be the centralized body for all countries facing a health threat, with the power to declare a “public health emergency of international concern,” issue recommendations, and work with countries to tackle a crisis. Although, with the sudden and rapid spread of COVID-19 in the world, many countries varied in implementing the WHO guidelines and health recommendations. While some countries followed the WHO guidelines, others imposed travel restrictions against the WHO’s recommendations. Some refused to share their data with the organization. Others banned the export of medical equipment, even in the face of global shortages. The UN Compliance Research group will focus during the current cycle on analyzing the compliance of the WHO member states to the organizations guidelines during the COVID-19 pandemic.

Authors: Broullón Lozano Manuel Antonio
Published: July 2021

El Archivo de la Fundación Federico García Lorca (AFFGL) es el punto de referencia más importante para la investigación lorquiana. En él se conservan todo tipo de objetos y documentos que alguna vez estuvieron en manos del autor: manuscritos, libros, documentos personales, cartas, efímeros, etc. En este ensayo pretendemos acercarnos a aquellas fuentes directamente relacionadas con la música, así como con las actividades musicales desarrolladas por Federico García Lorca. Ofreceremos la relación y descripción de los materiales encontrados en las sesiones de trabajo desarrolladas en la sede del Archivo durante el año 2019, incidiendo especialmente en aquellos que no están catalogados pero que podrían presentar algún interés de cara a futuras investigaciones.

La producción científica es parte fundamental de la actividad docente universitaria, como parte de la investigación y difusión del conocimiento científico. La producción científica se mide por la cantidad de documentos científicos publicados, como artículos y libros de investigación. Debido a la importancia de la publicación de artículos científicos para la docencia universitaria, se planteó la presente investigación en la que se analizaron factores determinantes para la publicación de artículos en revistas indexadas en Scopus y WoS de los profesores de la Universidad Nacional Agraria La Molina de Perú. Se realizó una búsqueda en el portal del Consejo Nacional de Ciencia, Tecnología e Innovación del Perú y se extrajo información de factores como: género, número de investigadores, registró como investigador, grado académico, años de servicio docente, nivel de inglés, tesis asesoradas, proyectos de investigación y artículos publicados. Como variable dependiente se utilizó la condición de si había o no publicado artículos y se realizó una regresión logística multinomial para establecer la dependencia de esta, de los factores. La producción científica de los docentes es baja y solo 17,9% son investigadores clasificados. Los determinantes de la publicación de artículos fueron el grado académico, asesorías de tesis y participación en proyectos de investigación. Se concluye que existe poca cultura científica, con docentes en su mayoría con más de 25 años de servicio y estudios de postgrado, con pocas tesis asesoradas, así como participaciones en proyectos de investigación, lo cual influye en la baja producción científica.
Spontaneous regression of solitary osteochondromas in children: An option to consider in clinical practice

Published: July 2021

Osteochondromas are neoplasm that belong to the family of cartilaginous histogenesis tumors and represent 90% of all forms of exostoses. As most osteochondromas are asymptomatic, underdiagnosis is frequent. Symptomatic forms usually manifest before the age of 20 years, and the most common symptoms are pain and the detection of a bony mass. Herein, we report four cases of spontaneous regression of solitary osteochondromas in the light of literature. We consider that orthopedic surgeons should take into account the possibility of spontaneous regression of these tumors, before recommending surgery. Symptoms are usually mild and we recommend following these patients with X-ray and physical examination annually.

Objectives: This study aims to investigate the prevalence and location of the metacarpophalangeal (MCP) sesamoid bones using computed tomography (CT) images.

Patients and methods: A total of 767 hands of 735 patients (503 males, 232 females; mean age: 36.9±17.0 years; range, 18 to 105 years) obtained from picture archiving and communication system were retrospectively analyzed between January 2016 and December 2019. The sesamoid bones of MCP joints I, II, III, IV, and V were recorded. Data including age, sex, side, number, pathologies, and location of the sesamoid bones were recorded.

Results: The prevalence of sesamoid bones was found to be 100%, 37.61%, 1.17%, 0.5%, and 80% in MCP I, II, III, IV, and V, respectively. There was no significant correlation between the sex of the patient and presence of sesamoid bone at MCP II or MCP V (p>0.970 and p=0.176, respectively). The presence of sesamoid bone at MCP II was statistically significantly correlated with the presence of sesamoid bone at MCP V (p<0.001). There was no statistically significant difference in the side and sesamoid prevalence in the remaining 703 patients (p>0.05).

Conclusion: The prevalence of MCP V sesamoid bone is higher than previous studies from our country. The CT of hand can be used to determine sesamoid fractures and degenerative conditions of sesamoids.
