title: Education and other determinants of older adults’ participation in labor force in Brazil

description: Abstract The extension of working life is associated with the accumulated years of schooling of individuals and with the characteristics of the pension system (COILE, 2018; GRUBER; WISE, 1999). In Brazil, people are acquiring years of education and beginning to work later. However, the availability of retirement programs make them leave early, despite increasing longevity (QUEIROZ; FERREIRA, 2021). This paper aims to characterize the changes in the labor force participation of elderly people across time, considering changes in the education composition. Census microdata were used (1980, 1991, 2000 and 2010), collected from IPUMS, and PNAD 2015. The labor force participation was estimated using binary logistic regression that considers potential determinants and represents the inequalities marking the context. Results show that the propensity to work is positively associated with schooling. However, little has changed regarding the working conditions of the elderly. The vulnerability faced by this labor force persists across time as do disadvantages for women and black people.

title: Effect of environmental factors on the fruit essential oils of Pistacia terebinthus L. growing wild in Turkey

description: ABSTRACT Background: The aim of this study was to investigate the effect of environmental factors on the essential oil yields (EOYs) and major essential oil components in the ripe fruits of Pistacia terebinthus L. (turpentine tree), which is a medicinal and aromatic plant. Fruit samples were collected from 34 different locations of the turpentine tree growing wild in the Lake District in the Mediterranean Region of Turkey. EOYs (%, v/w) and essential oil component ratios (%) were determined in fruit samples by hydrodistillation and GC-MS methods, respectively. The effect of environmental factors on these variables were analyzed using Pearson Correlation and Principal Component Analysis. Results: The essential oil yield of fruits collected from different localities ranged from 0.05% (v/w) to 0.19% (v/w). In terms of average values, α-pinene with 41.01% and limonene with 14.28% were the major components in the essential oils of ripe fruits. Among the environmental variables, longitude and sand % in 10-30 cm were the variables that made a statistically significant difference (p &lt; 0.05) in fruit essential oil yield. According to the results of principal components analysis (PCA), α-pinene and Ocimene components were most affected by silt (%, 10-30 cm) and pH (%, 30-50 cm) ratios. The longitude and total annual precipitation (mm) were the most determining variables in the sabinene and limonene components, respectively. It was seen that the total lime ratios at different depth levels of the soils taken from the localities were the most effective variables for Myrcene and p-Cymene components. Conclusion: The study findings showed that EOYs and intended volatile component ratios in ripe fruits of turpentine trees grown under appropriate environmental conditions can be increased.

title: Semi-hard buffalo cheese: how cow's milk affects sensory acceptance?

description: Abstract This study aimed to highlight the effect of cow milk addition (0, 15, 30, and 45%) on Brazilian semi-hard buffalo cheese. Four formulations with different buffalo and cow milk ratios (v/v) were prepared: CC00 (100:00%); CC15 (85:15%); CC30 (70:30%); and CC45 (55:45%). The CC00 presented the highest moisture, fat in dry matter, and salt contents, while CC45 exhibited the highest protein and lowest pH values. CC45 presented the highest flavor, texture, overall acceptability, and purchase intention. Therefore, cow milk addition at 45% is an alternative to improve Brazilian semi-hard buffalo cheese's acceptability and purchase intention and, consequently, a market opportunity for the diversification of buffalo dairy products.

title: Bending quality of three Brazilian hardwoods modified by different hydrothermal treatments

description: ABSTRACT Background: Boiling, steaming, and microwave radiation treatments were used for softening and then manufacturing curved samples using three Brazilian hardwoods. Solid wood samples from Carya illinoinensis, Luehea divaricata and Platanus x acerifolia were characterized for bending quality, bending defects, minimum radius of bending, spring-back and moisture content. Results: Among the studied woods, Carya illinoinensis wood was the most suitable to conform curved samples since 96.7% of these wood samples reached a perfect curved shape. On the other hand, Luehea divaricata wood presented the worst behaviour, which was marked by only 36.7% of samples achieving a perfect shape. In general, the studied hydrothermal treatments and exposure times induced similar softening behaviours. Conclusion: In this sense, microwave heating seems to be a good option when compared to the other pathways, since it is known that this method require low consumptions of both time and energy.

title: ABEM consensus for the brazilian medical schools’ communication curriculum

description: Abstract: Introduction: Communication is an essential competence for the physician and other professional categories, and must be developed their professional training. The creation of a communication project including a Brazilian consensus aimed to subsidize medical schools in preparing medical students to communicate effectively with Brazilian citizens, with plural intra and inter-regional characteristics, based on the professionalism and the Brazilian Unified System (SUS) principles. Objective: The objective of this manuscript is to present the consensus for the teaching of communication in Brazilian medical schools. Method: The consensus was built collaboratively with 276 participants, experts in communication, faculty, health professionals and students from 126 medical schools and five health institutions in face-to-face conference meetings and biweekly or monthly virtual meetings. In the meetings, the participants’ experiences and bibliographic material were shared, including international consensuses, and the consensus under construction was presented, with group discussion to list new components for the Brazilian consensus, followed by debate with everyone, to agree on them. The final version was approved in a virtual meeting with invitation to all participants in July 2021. After the submission, several changes were required, which demanded new meetings to review the consensus final version. Result: The consensus is based on assumptions that communication should be relationship-centered, embedded on professionalism, grounded on the SUS principles and social participation, and based on the National Guidelines for the undergraduate medical course, theoretical references and scientific evidence. Specific objectives to develop communication competence in the students are described, covering: theoretical foundations; literature search and its critical evaluation; documents drafting and editing; intrapersonal and interpersonal communication in the academicscientific environment, in health care and in health management; and, communication in diverse clinical contexts. The inclusion of communication in the curriculum is recommended from the beginning to the end of the course, integrated with other contents and areas of knowledge. Conclusion: It is expected that this consensus contributes the review or implementation of communication in Brazilian medical schools’ curricula.

title: EPIDEMIOLOGICAL STUDY OF SURGICALLY TREATED HUMERAL SHAFT FRACTURES - A 10-YEAR REVIEW

description: ABSTRACT Most epidemiological studies do not exclusively address fractures treated surgically but include those with conservative treatment. In Brazil, few epidemiological studies address fractures prevalence undergoing surgical treatment. Objective: To assess the prevalence, demographics, and associated injuries of surgically treated humeral shaft fractures. Methods: A retrospective study between 2009 and 2019 with patients undergoing osteosynthesis of humeral shaft fracture. Categorical variables were assessed using Fisher’s chi-square or exact test, and non-categorical variables were assessed using the unpaired t-test. A significance level of 5% was adopted. Results: A total of 115 patients were evaluated. Mean age was 37.9 ± 15.6 years, with a male predominance (66.9%) due to car accidents. The most prevalent fracture type was 12 A3. Open fracture prevalence was 11.3%. Radial nerve damage prevalence was 33% and low-energy trauma was twice as likely. Conclusion: Surgically treated humeral shaft fractures were more prevalent in men, young, and related to high-energy trauma, with a transverse line pattern. Fractures secondary to low-energy trauma had a greater association with radial nerve injury. Level of Evidence III, Epidemiological, Retrospective Study.

title: Clinically silent Plasmodium vivax infections in native Amazonians of northwestern Brazil: acquired immunity or low parasite virulence?

description: BACKGROUND Malaria remains common among native Amazonians, challenging Brazil′s elimination efforts. OBJECTIVES We examined the epidemiology of malaria in riverine populations of the country′s main hotspot - the upper Juruá Valley in Acre state, close to the Brazil-Peru border, where Plasmodium vivax accounts for &gt; 80% of cases. METHODS Participants (n = 262) from 10 villages along the Azul River were screened for malaria parasites by microscopy and genus-specific, cytochrome b (cytb) gene-based polymerase chain reaction. Positive samples were further tested with quantitative TaqMan assays targeting P. vivax- and P. falciparum-specific cytb domains. We used multiple logistic regression analysis to identify independent correlates of P. vivax infection. FINDINGS Microscopy detected only one P. vivax and two P. falciparum infections. TaqMan assays detected 33 P. vivax infections (prevalence, 11.1%), 78.1% of which asymptomatic, with a median parasitaemia of 34/mL. Increasing age, male sex and use of insecticide-treated bed nets were significant predictors of elevated P. vivax malaria risk. Children and adults were similarly likely to remain asymptomatic once infected. MAIN CONCLUSIONS Our findings are at odds with the hypothesis of age-related clinical immunity in native Amazonians. The low virulence of local parasites is suggested as an alternative explanation for subclinical infections in isolated populations.

title: Access to higher education: normative effectiveness of socioeconomic quotas

description: Abstract Affirmative actions are special and temporary measures that aim to reduce inequalities and guarantee opportunities for vulnerable individuals. One of them is to reserve spots at universities for students from public schools. The purpose of this article is to assess whether this action model has normative effectiveness within the scope of the Faculty of Law of UERN (Rio Grande do Norte, Brazil) and to map experiences in this regard. It is a case study, with academic, legal and social relevance, as it contributes to the debate on the theme, evaluates social policies and impacts on institutional life. As a result of an exploratory, bibliographic and documentary research, deductive method and quantitative approach, finding out that, considering the area analyzed, quota students complete the Law course in the same period when compared to non-quota students. Thus, this affirmative action has been shown to be effective to meet the expectations generated by the instituting law, guaranteeing entry and training in an equitable manner to people with less acquisition power.
