title: Meditation for stress and anxiety relief in undergraduate students: a randomized clinical trial

description: Abstract: Introduction: Stress is a state in which the body homeostasis is threatened, leading to adaptive, physiological and behavioral responses. Anxiety is an unpleasant feeling that occurs whenever a future potential threat is perceived. Whenever these states are prolonged, both lead to metabolic, cardiovascular, neuropsychiatric and immunological consequences. University students are more susceptible to stress and anxiety symptoms than the general population. Mindfulness is a technique that allows its practitioners to become more aware of their emotions, dealing with stress in a more skilled way. Objective: To; evaluate the efficacy of a modified mindfulness program in reducing stress and anxiety symptoms in medicine and dentistry undergraduate students. Methods: This was a single blinded, randomized, clinical trial. Students from the aforementioned courses enrolled in the 1st to the 8th semesters of a higher education institution, answered Lipp’s Inventory of Stress symptoms for Adults (ISSL) (n=418) and the State-Trace Anxiety Inventory (STAI) (n=369). Those who showed a positive score for symptoms of stress and/or anxiety and accepted to take part in the intervention (n=59), were randomized into one of the two groups - mindfulness (a 2-week modified program), or control. After the intervention, the students were asked to answer the STAI and ISSL tools once again. Results: The global prevalence of stress and anxiety symptoms were 67% (n=280) and 76.4% (n=282), respectively. At the end of the second week, symptoms of stress and anxiety decreased 30.8% and 22.2%, respectively. There were no statistically significant differences between the mindfulness and control groups (p&gt;0.05). Conclusion: Symptoms of stress and anxiety are highly prevalent among the studied population. Among medicine and dentistry undergraduate students in this higher education institution, a shortened mindfulness program was unable to reduce symptoms of stress and anxiety in a statistically significant way when compared to a control group.

title: Characterization of Dutch-Cocoa produced using potash extract from cocoa pod husk as an alkalizing bioresource

description: Abstract Alkalizing agents in the processing of Dutch-Cocoa are often imported from developing countries. This occurs amidst humongous quantities of Cocoa Pod Husk (CPH) that are largely rotting away. This study therefore appraises the inherent alkalizing potentials of CPH, including its physicochemical and safety characteristics in the production of Dutch-Cocoa. CPH was calcined, potash extracted, characterized, and applied in formulation (1% to 5% conc.) in Dutch-production of Cocoa. Quality parameters of the resultant product were analyzed following AOAC procedures (p ≤ 0.05). In addition, rats(n=30) were fed it over a 21-day duration while nutritional and safety indicators were monitored. Sensory properties were also evaluated. The results showed some predominant properties of CPH potash extract [Potassium 35.7%, pH 12.3, alkalinity 15.6 g/100 g CO3] and Dutch-cocoa [protein (15.8% to 16.5%), colour (Hunter L,a,b) 36.9, 8.8, 11.7 light - dark red), dispersibility (1.5 to 2.3), wettability (143.7 s), sedimentation (20.7% to 49.3%)] which favourably compared with commercial variants. Apparent digestibility (AD%) was significant (Protein 86%, Fat 88%, Fiber 66% etc) (p ≤ .0.05). Safety indices exhibited no deleterious effect and the product was adjudged acceptable. Dutch-cocoa produced using CPH-derived-potash as an alternate alkalizing bioresource is feasible, while simultaneously providing an environmentally friendly outlet for CPH

title: Efficiency of chemical preservatives used in raw milk samples for bacterial counts by flow cytometry

description: ABSTRACT The objective of this study was to evaluate and compare two chemical preservatives in terms of their sample preservation capabilities, considering the individual bacterial count (IBC) and time and temperature variables. Samples were collected in expansion tanks in three commercial dairy farms located in the northwest of Rio Grande do Sul, characterized as G1: low IBC values, G2: average IBC values, and G3: high IBC values. The tanks were stored at three different temperatures (4, 10, and 25 °C) for 14 d. Samples supplemented with the preservative Azilat in G1 (lower IBC group) exhibited the best results at a temperature of 4 °C, whereas for G2 and G3, the results showed no statistically significant difference between temperatures 4 and 10 °C. The temperature 25 °C exhibited the worst results. For samples preserved with Azidiol, regardless of the studied group (G1, G2, and G3), the temperatures of 4 and 10 °C did not present a significant difference regarding the preservation of the samples, with the temperature of 25 °C exhibiting the worst results. Azilat was effective in keeping the samples conserved when they presented low IBC, being able to fluctuate with the increase in IBC and temperature variation. Azidiol was effective regardless of the initial IBC level.

title: International trends of orthodontic publications: A bibliometric observational study of the last decade (2011-2020)

description: ABSTRACT Introduction: The number of published orthodontic studies has increased considerably over the past ten years. Objective: To analyze the bibliometric data of international orthodontic studies included in orthodontic journals encompassed by the Scopus database between 2011 and 2020, as well as to undertake data comparison between the period 2010-2015 and the period 2016-2020. Materials and methods: A retrospective search was conducted on 14 orthodontic journals included in the Scopus database from 2011 to 2020. Studies of both primary and secondary types were targeted by the search. The yearly number of studies published in the 14 journals, and the first 20 countries, institutions and their type (public/private), and authors, respectively, regarding publication volume, were presented. Results: Over the past ten years, the number of publications in the chosen journals reached 9200, where the American Journal of Orthodontics and Dentofacial Orthopedics and Angle Orthodontist topped the journal list, with 22% and 12% of the publications, respectively. Furthermore, the orthodontic publication volume showed a declining trend by the end of the decade (-9%), where academic/public institutions produced most of the orthodontic studies, and the US (20%), Brazil (17%), and South Korea (8%) topped the countries with the most orthodontic studies. A comparison of the two halves of the decade revealed that orthodontic research exhibited an increasing trend in developing nations, especially Egypt (104%), Saudi Arabia (88%), and Iran (83%). Conclusion: The orthodontic studies published in the chosen journals over the past ten years showed a dynamic change in yearly publication and ranking of countries, institutions, and authors.

title: Student-related aspects in the construction of the Medical Identity: an integrative review

description: Abstract: Introduction: The Medical Identity (MI) construction is a dynamic phenomenon influenced by factors related to the student, the educational environment and society. Objective: To synthesize the produced knowledge about the student-related aspects regarding the construction of the MI. Method: This is an integrative review of empirical studies published in journals indexed in the MEDLINE and LILACS databases, using the term Medical Identity and the descriptors Identity Crisis, Social Identification, Physician’s Role and Professional Role. The inclusion criteria were: full texts available in Portuguese, Spanish, French or English of empirical studies on factors that influence the development of MI focused on student-related aspects and having physicians or undergraduate medical students as participants. Results: In the first stage, 1,365 articles were identified. Subsequently, 194 articles were chosen for in-depth reading. Of these, 18 were included for thematic analysis with classification into categories in dialogue with the literature, based on the concept of healthy MI. Most articles were published in the last decade. Three categories were identified: expectation versus reality, related to what the student thinks about what a physician is or should be; the ‘superhero’ physician, related to the caricatured perception of Medicine created by the students themselves and offered by society through TV programs, series and films; and role modeling, which concerns the importance of the student’s practical experience supervised by a preceptor or teacher. The MI built throughout the medical course influences the way medicine is practiced and when it is not consistent with the reality that the recently graduated student encounters, it causes suffering to the physician and interferes with their professional performance. Conclusion: Educational institutions, teachers and preceptors must be aware of the expectations and ideals of their students about what it means to be a physician and the role of this professional in society, aiming to promote interventions that help establishing a healthier and more resilient identity construction, particular to the medical profession.

title: VIBRATION TRANSMISSIBILITY OF THE COFFEE FRUIT-PEDUNCLE SYSTEM: A FORCED VIBRATION STUDY OF HIGH FREQUENCY AIMING MECHANICAL HARVESTING

description: ABSTRACT Semi-mechanized and mechanized harvesting use machines that promote the transference of vibrational energy and impact to achieve the detachment of coffee fruits. The aim of this study was to evaluate the vibration transmissibility in coffee fruit-peduncle systems, using high-speed cameras, submitted to high frequency harmonic excitation in different combinations between frequency and amplitude of vibration, identifying working ranges suitable to perform selective harvesting. Vibration transmissibility was determined for the coffee fruit-peduncle systems, for the maturation stages unripe and ripe that were subjected to a sinusoidal harmonic displacement, in which the input parameters were frequency (35, 45 and 55 Hz) and peak-to-peak amplitude (3.5, 5.0 and 6.5 mm). An experiment was used to study the effect of frequency and amplitude on vibration transmissibility in a completely randomized design in a factorial scheme 3 x 3 x 2, with three replications. The frequency of 35 Hz, associated with the amplitudes 3.5-6.5 mm, was the one that most influenced the results of vibration transmissibility. For the frequency of 55 Hz and amplitude of 6.5 mm, in the ripe maturation stage, the vibration transmissibility was higher than 1.0, which could be a suitable combination for selective coffee harvesting.

title: Floristic characterization and pollen morphology of plants visited by Apis mellifera L. in caatinga areas in Bahia, Brazil

description: ABSTRACT The aim of this study was to identify plant species visited by Apis mellifera L. in honey producing areas with typical Caatinga vegetation in the State of Bahia, as well as morphologically characterize pollen grains of the most representative species. Flowering specimens were collected from both areas, herborized, identified and deposited at the HUNEB herbarium. Analyses of floristic similarities were performed between eleven municipalities close to the study areas. Pollen was collected from all specimens, acetolyzed, measured, statistically analyzed, morphologically described, and photographed in light microscopy. Of the total of species recorded, 67.46 % were regarded as having beekeeping importance, with the richest botanical families being Fabaceae, Malvaceae and Asteraceae. Additionally, 37.5 % of the recorded species were herbs. The analyzed municipalities showed 84 % of floristic similarity. Of the total species recorded with visits by A. mellifera, 25.52 % had their pollen grains already described in the literature as monads, tetrads and polyads; isopolar, apolar and heteropolar; and mostly prolate spheroidal shape. Sizes varied from small to large, and the amb circular was predominant. The exine ornamentation was greatly diversified, varying from psilate to echinate. The obtained data corroborate the palynological knowledge of plants regarded as having beekeeping importance within the Caatinga.

title: The field of study of sociocultural perspectives on Educational Mathematics: collaboration, intellectual structure, and thematic areas

description: Abstract: Ethnomathematics studies the relationship between mathematics and culture, taking advantage of contextual elements to identify mathematical processes implicit in cultural practices. The aim of this study was to analyze the state of scientific production published in Scopus (2000-2021) on ethnomathematics and cultural aspects of mathematics. Through an empirical, retrospective study based on bibliometric techniques, 831 articles were analyzed to identify indicators of academic collaboration, intellectual structure according to co-authorship networks and bibliographic coupling of authors and sources, as well as the exploration of the main thematic subjects through co-occurrence networks. An increase in cooperative links between researchers was identified, with a growing importance of Indonesian and Brazilian authors. The thematic field is wide-ranging, including teaching practices, ethnography in educational mathematics, transculturality and ethnomathematical applications in diverse areas. This approach shows mathematical knowledge as a cultural product, of universal domain and not exclusively circumscribed to academic groups.
