Published: October 2021

Introducción: La pandemia por COVID-19 y las medidas de confinamiento han generado la necesidad de reestructurar las metodologías de enseñanza en educación superior, pero de forma rápida y en ocasiones de manera exploratoria. Objetivo: Describir la percepción de estudiantes de la carrera de Nutrición y Dietética frente al cambio de educación presencial a formato online en el contexto de la pandemia. Método: Estudio descriptivo, transversal. Se aplicó un cuestionario con 32 preguntas en escala de Likert a través de Google Forms posterior a la aceptación del consentimiento informado en estudiantes entre 1º-4º año. Se realizó análisis descriptivo a través de porcentajes y medias. Se llevaron a cabo análisis de Alfa de Cronbach y factorial exploratorio para validación del instrumento. Se realizaron asociaciones de variables cualitativas a través de chi2. Se consideró significancia estadística con p <0.05. Se utilizó software SPSS versión 24.Resultados: Respondieron la encuesta 126 estudiantes. 94.4% fueron mujeres. 56% prefiere las videoconferencias sincrónicas como metodología para realizar las clases teóricas y el 30% refiere que las actividades prácticas no son reemplazables por una metodología online. Los aspectos académicos presentan percepciones de preferencia acuerdo y totalmente de acuerdo; sin embargo, el 63% de los estudiantes de primer y segundo año refieren que la relación con los profesores no es la misma que en formato presencial. El 87% percibe que destina mayor tiempo en desarrollar actividades propias de las asignaturas a diferencia de cuando estas se impartían de forma presencial.Conclusiones: La percepción de los alumnos es positiva con respecto a los aspectos académicos; sin embargo, han expuesto baja aceptación en aspectos sociales como la relación con otros compañeros. Además, según la percepción de los estudiantes, las actividades prácticas y de trabajo clínico no serían reemplazables por metodologías en línea.

Fundamentada na perspectiva da psicologia escolar e educacional crítica, a presente pesquisa, realizada em um município baiano, objetivou conhecer as concepções de educadores e psicólogos sobre o encaminhamento das crianças com queixa escolar para serviços de saúde e investigar as modalidades de atendimento a esse fenômeno. De caráter qualitativo e exploratório, foi realizada uma entrevista semiestruturada, aplicada de forma individual, totalizando 12 participantes, cujas respostas foram organizadas em categorias temáticas relacionadas aos objetivos da pesquisa. Nas entrevistas, prevaleceu a concepção de que questões de ordem educacional e também familiares/sociais justificam os problemas de escolarização das crianças, cujo encaminhamento aos serviços de saúde tem sido a alternativa possível, mas não a ideal para avaliação e intervenção. Espera-se que os referidos achados suscitem novos estudos sobre o tema investigado, especialmente no município em questão, que favoreça o fortalecimento dos pressupostos da psicologia escolar/educacional crítica no meio acadêmico. Ressalta-se ainda a necessidade de fomentar essa discussão de forma intersetorial na rede municipal de educação e saúde, problematizando a compreensão e atendimento às queixas escolares, e que se possam produzir práticas psicológicas e educativas críticas e emancipadoras.
MEMBRAN POLIURETAN DARI MINYAK BIJI KARET (RUBBER SEED OIL) DENGAN HEKSAMETILEN-1,6-DIISOSIANAT: SINTESIS
Authors: Nurman Salfauqi , Marlina Marlina , Saiful Saiful 
Published: October 2021

Polyurethane membrane made from Rubber Seed Oil has been produced within this research. Rubber seed oil has the hydroxyl number of 40,33 mg/g and the iodine number of 154,05 g/g which can be used as resource clusters; -OH, in order to make polyurethane. Rubber seed oil can react with hexamethylene-1.6-diisocyanate (HDMI) as another resource cluster, which is -NCO. The production of polyurethane membrane is done by variating the composition of rubber seed oil and HDMI, with the variations of 5:1; 5:3; 5:4; 5:5 dan 5:7 (v/w) and the polymrization temperature of 90-100°C and the curring temperature of 165-170°C. The optimal polyurethane membrane is produced on the composition of 5:4 v/w which is homogenous, dry, quite elastic and is yellowish brown in colour. The IR results showed that there were urethan bonds formed (N-H on ν = 3300-3400 cm-1) and the TGA results from polyurethane membrane showed that there were two decompositions on 394,5oC dan 458,6oC.

Published: October 2021

The research was conducted in order to identify the distribution of seismicity, repeated periods of earthquakes and the probability of earthquake in Sumatra using Likelihood Maximum methods. Earthquake data from the ISC and USGS catalogue were used. Earthquake data from 1914-2014 (100 year span) with magnitude of (M)≥5 SR and depth (h)≤100 km that is located at 60LS – 100LU and 920BT – 1080BT. The latitude and longitude coordinates were divided into 21 regions. The results showed distribution of seismicity in Sumatran as much as 3634 events of earthquake during the 100 last years. The distribution of seismicity in Sumatra is quite high. From data shown, there was value a, which is between 4.81 - 9.94 and value b which is between 0.54 - 1.32. This condition indicated an index value of M≥5 SR, which is between 0.006 - 0.076 and repeated periods between 13 - 175 years with the probability of earthquake M≥5 SR between 5.6% - 99.9% for T (time) = 10, 50 and 100 years.

Published: October 2021

This research aims to synthesize polyurethane membrace from avocado seed oil as a source of hydrixyl (-OH) and hexametylhene -1.6-dissocyanate (HDMI) as a source of isocynate (-NCO). The oil were extracted from avocado seeds at temperature of 60-80oC for 2 hours using n-hexane solvent. The results of FTIR spectrum analysis from avocado seed oil showed that there were -OH clusters absorption on the wavelength number of 3393.819 cm-1, thus this oil can be used to synthesize polyurethane membrane. The isocyanate composition, time and temperature during synthesis process of polyurethane membrane were varied. The polyurethane membrane were moulded in petri dishes, then heated up for 48 hours on the temperature of 70oC, and finally taken out from its mould. The characteristics of the polyurethane membrane from avocado seed oil are brown in colour, homogenous, elastic, solid, transparent and shaped like a membrane. The measurements from FTIR spectrum showed that the -NCO clusters are no longer present. This condition happened because there were no more absorption in the wavelength number of 2270 cm-1 . It can be concluded that the isocyanate has completely reacted during polymerization and the curing process, thus urethane was created in the 1699,965 cm-1 absorption which was the urethane C=O clusters absorption.

Published: October 2021

ABSTRACTConodont assemblages from shallow platform carbonate strata of the Dyer Formation in northwestern Colorado indicate that the unit spans the Devonian–Carboniferous transition, and include four new taxa, described herein. The underlying Parting Formation and most of the Broken Rib Member of the Dyer Formation are in the Palmatolepis expansa Zone. The upper portion of the Broken Rib Member and the lower part of the Coffee Pot Member of the Dyer Formation are in the Bispathodus aculeatus Zone to the Bispathodus ultimus Zone, and associated with an ~6‰ positive δ13C shift identified as the end-Devonian Hangenberg excursion. Upper Coffee Pot Member conodonts are equivocally Tournaisian, and cap the δ13C excursion. Collectively, these observations suggest that the Devonian–Carboniferous boundary is in the upper Coffee Pot Member of the Dyer Formation, and thus the overlying Gilman Sandstone is Carboniferous.

Published: October 2021

Introduction:
Oral health is governed by a multitude of factors and of importance among these is diet and nutrition. Patients need to be made aware of the effect diet and nutrition has on their oral health. Patients should also be encouraged to reduce the frequency of intake of sugary foods. Dentists need to have adequate knowledge regarding diet and nutrition and its effects on oral health. Dental students can be targeted at an early stage as they will be the beacons of dentistry and carry on the knowledge into private practice.

Aim:
The aim of the study was to assess the knowledge of the undergraduate dental students regarding diet and nutrition and its impact on oral health and to assess their attitude and practice towards the same.

Methods:
A cross sectional questionnaire based study was carried out among 203 undergraduate students (122 third BDS, 22 Final BDS and 59 Residents) from dental colleges in Davangere, Karnataka. The responses were subjected to statistical analysis using SPSS (Statistical Package for the Social Sciences) version 22 and the tests used were Frequency distribution and Pearson Chi-Square test.

Results:
Most of the participants (82.3%) were aware that sucrose is the most cariogenic sugar. 84.2% of the students knew the type of food that helps in preventing dental caries and strengthening the periodontium, yet only a few (19.2%) were able to correctly choose the most anticariogenic food among the options.

Conclusion:
While most of the students were aware of the basic knowledge of diet and nutrition and its effect on the oral health, their attitude and eagerness towards the concept should be nurtured through extensive and in detail addition of diet in the curriculum to ultimately help patients maintain a better oral hygiene and prevent oral diseases.

Since the first ESFRI roadmap in 2006, multiple humanities Research Infrastructures (RIs) have been set up all over the European continent, supporting archaeologists (ARIADNE), linguists (CLARIN-ERIC), Holocaust researchers (EHRI), cultural heritage specialists (IPERION-CH) and others. These examples only scratch the surface of the breadth of research communities that have benefited from close cooperation in the European Research Area. While each field developed discipline-specific services over the years, common themes can also be distinguished. All humanities RIs address, in varying degrees, questions around research data management, the use of standards and the desired interoperability of data across disciplinary boundaries. This article sheds light on how cluster project PARTHENOS developed pooled services and shared solutions for its audience of humanities researchers, RI managers and policymakers. In a time where the convergence of existing infrastructure is becoming ever more important – with the construction of a European Open Science Cloud as an audacious, ultimate goal – we hope that our experiences inform future work and provide inspiration on how to exploit synergies in interdisciplinary, transnational, scientific cooperation.

Objective: Atherosclerosis is an arterial occlusive disease with hypercholesterolemia and hypertension as common risk factors. Advanced-stage stenotic plaque, which features inflammation and necrotic core formation, is the major reason for clinical intervention. Receptor interacting serine/threonine-protein kinase 1 (RIPK1) mediates inflammation and cell death and is expressed in atherosclerotic lesions. The role of RIPK1 in advanced-stage atherosclerosis is unknown.Approach and Results: To investigate the effect of RIPK1 inhibition in advanced atherosclerotic plaque formation, we used ApoESA/SA mice, which exhibit hypercholesterolemia, and develop angiotensin-II mediated hypertension upon administration of doxycycline in drinking water. These mice readily develop severe atherosclerosis, including that in coronary arteries. Eight-week-old ApoESA/SA mice were randomized to orally receive a highly selective RIPK1 inhibitor (RIPK1i, GSK547) mixed with a western diet, or control diet. RIPK1i administration reduced atherosclerotic plaque lesion area at 2 weeks of treatment, consistent with suppressed inflammation (MCP-1, IL-1β, TNF-α) and reduced monocyte infiltration. However, administration of RIPK1i unexpectedly exacerbated atherosclerosis at 4 weeks of treatment, concomitant with increased macrophages and lipid deposition in the plaques. Incubation of isolated macrophages with oxidized LDL resulted in foam cell formation in vitro. RIPK1i treatment promoted such foam cell formation while suppressing the death of these cells. Accordingly, RIPK1i upregulated the expression of lipid metabolism-related genes (Cd36, Ppara, Lxrα, Lxrb, Srebp1c) in macrophage foam cells with ABCA1/ABCG1 unaltered. Furthermore, RIPK1i treatment inhibited ApoA1 synthesis in the liver and reduced plasma HDL levels.Conclusion: RIPK1 modulates the development of atherosclerosis in a stage-dependent manner, implicating both pro-atherosclerotic (monocyte infiltration and inflammation) and anti-atherosclerotic effects (suppressing foam cell accumulation and promoting ApoA1 synthesis). It is critical to identify an optimal therapeutic duration for potential clinical use of RIPK1 inhibitor in atherosclerosis or other related disease indications.
RETRACTED: Adverse Pregnancy Outcomes Following Exposure to Biologics in Women With Crohn's Disease: A Systematic Review and Meta-Analysis

Published: October 2021

Crohn's disease is a chronic disease, which commonly affects women during their reproductive years. Poorly treated Crohn's disease is associated with adverse pregnancy outcomes. Biologics, a group of therapeutic drugs targeting inflammatory mediators including anti-TNF, anti-integrins and anti-interleukins, are increasingly used in pregnant women with Crohn's disease, exposing both the women and their fetuses to treatment-related complications. At present, it is unclear which biologics are more superior. This study performed a systematic review and meta-analysis to assess the risk of adverse pregnancy outcomes in women with Crohn's disease after exposure to biologics. Bibliographic databases were searched from inception to May 2021. The outcomes of interest were preterm delivery, low birth weight, spontaneous abortion, and congenital abnormalities. A total of 11 studies comprised of 1,875 pregnancies among women with Crohn's disease were included. Of these, 1,162 received biologics and 713 received non-biologic therapy. During the remission phase of the disease, the use of biological therapy increased the risk of adverse pregnancy outcomes, of which anti-integrins were associated with a higher incidence of adverse pregnancy outcomes than anti-TNF and anti-interleukins.Systematic Review Registration:http://www.crd.york.ac.uk/PROSPERO, identifier: CRD42020191275.

Published: October 2021

Objective: Epilepsy is a chronic disease that places a heavy burden on caregivers. Previous studies have shown that caregivers of epilepsy patients often experience anxiety and depression; however, few comprehensive studies have assessed their sleep quality and family function. Based on the current understanding of the anxiety and depression state of caregivers in children with epilepsy, we further explored the caregivers' sleep and family function and evaluated the predictors of the depression state of caregivers.Methods: In this cross-sectional online anonymous survey, we sent an online questionnaire to the caregivers of children with epilepsy who visited our hospital. The QR code of the questionnaire was scanned at the follow-up course to conduct an online survey. The questionnaire contained questions about sociodemographic and clinical information, the Self-rating Anxiety Scale, Self-rating Depression Scale, Pittsburgh Sleep Quality Index, and the Family Assessment Device.Results: A total of 308 caregivers of children with epilepsy aged 0–12 years were included in this study. The mean age of children with epilepsy was 4.8 ± 3.18 years, and the average illness duration was 34.2 ± 29.18 months. Further, 47.1% of the children took three or more anti-seizure medications, and 43.2% were on ketogenic diet therapy. We found that in 77.9% of the cases, the subjects were the mothers, in 89% there was more than one co-caregiver, and in 51.9%, financial help was required. Further, 63.6% of the caregivers thought they could not get enough access to disease knowledge education, and 83.7% perceived epilepsy was a terrible disease. Our results also showed that 65.6% of the caregivers were in depression status, 41.9% were in anxiety status, and 49.0% had poor sleep quality. The proportion of unhealthy family functioning in each subscale was 45.1–96.1%, and the unhealthy behavior control function accounted for 96.1%. Binary logistic regression analysis of the data showed that without co-caregivers [odds ratio (OR), 5.193], free of anxiety status (OR, 0.063), good sleep quality (OR, 0.446), healthy family role dimension (OR, 0.344), and healthy family general functional dimension (OR, 0.259) were predictors of depression status in caregivers of children with epilepsy.Conclusion: Anxiety and depression status are common in caregivers of children with epilepsy, with depression status being more prominent. Moreover, a considerable proportion of caregivers had poor sleep quality and unhealthy family function. The caregivers' anxiety status, sleep quality, family role dimension, family general function dimension, and the number of co-caregivers were predictors of depression status in caregivers. In clinical practice, caregivers' anxiety and depression status, poor sleep quality, and unhealthy family functioning should be addressed along with the treatment of children with epilepsy.

Purpose: Tension-type headache (TTH), the most prevalent primary headache disorder, imposes an enormous burden on the people of the world. The quest to ease suffering from this neurological disorder has sustained research interest. The present study aimed at evaluating the amplitude of low-frequency oscillations (LFOs) of the brain in multiple frequency bands in patients with TTH.Methods: To address this question, 63 participants were enrolled in the study, including 32 TTH patients and 31 healthy controls (HCs). For all the participants, amplitude of low-frequency fluctuation (ALFF) was measured in six frequency bands (conventional frequency bands, 0.01–0.08 Hz; slow-2, 0.198–0.25 Hz; slow-3, 0.073–0.198 Hz; slow-4, 0.027–0.073 Hz; slow-5, 0.01–0.027 Hz; and slow-6, 0–0.01 Hz), and the differences between TTH patients and HCs were examined. To explore the relationship between the altered ALFF brain regions in the six frequency bands and the Visual Analog Scale (VAS) score in the TTH patients, Pearson’s correlation analysis was performed.Results: In all the six frequency bands, a decreased ALFF value was detected, and regions showing reduced ALFF values were mostly located in the middle frontal gyrus and superior gyrus. A frequency-dependent alternating characterization of intrinsic brain activity was found in the left caudate nucleus in the slow-2 band of 0.198–0.25 Hz and in the right inferior frontal orbital gyrus in the slow-5 band of 0.01–0.027 Hz. For the correlation results, both the left anterior cingulate and paracingulate gyri and right superior parietal gyrus showed a positive correlation with the VAS score in the slow-4 frequency band of 0.027–0.073 Hz.Conclusion: The ALFF alterations in the brain regions of TTH patients are involved in pain processing. The altered LFOs in the multiple regions may help promote the understanding of the pathophysiology of TTH. These observations could also allow the future treatment of TTH to be more directional and targeted and could promote the development of TTH treatment.
