Larvicidal Activity of Leaf Extract From Mauritiella armata (Aceraceae) on Aedes aegypti and Culex quinquefasciatus (Culicidae)

The mosquitoes Aedes aegypti and Culex quinquefasciatus (Diptera: Culicidae) are important vectors of several arboviruses, and are relevant public health problems. Conventional control, using chemical larvicides have selected resistant Culicidae populations and caused negative effects on the environment and human health. However, the use of plant extracts has represented a sustainable alternative for insect control. Popularly known as Xiriri, Mauritiella armata (Mart.) Burret (Aceraceae) is an abundant palm tree in Vereda ecosystems and has economic and social importance. In this study, the aim was to evaluate the larvicidal activity of the aqueous extract (AE) leaves of this plant on Ae. aegypti and Cx. quinquefasciatus larvae. The mortalities of larvae were analyzed after treatment with four concentrations of the extract, comparing with a negative control using mineral water. The AE promoted 100% efficacy against Ae. aegypti larvae at 7.9 mg/mL. The lethal concentration to promote 90% mortality of Cx. quinquefasciatus larvae was estimated at 30.57 mg/mL. After chromatographic analyses, flavonoids, catechin and carbohydrates were detected. AE from M. armata leaves presented high larvicidal activity against Ae. aegypti and Cx. quinquefasciatus, and represents a promising alternative to be used in vector control.

How to avoid medical errors, how to respond and relate to them: a review of the scientific monograph «Defects in the provision of medical care»

Currently, the number of judicial proceedings on real and alleged offenses and disputes in area of provision of medical care has been exponentially increased. Some of such proceedings become publicly disclosed, but many more of them remain unnoted in mass media and civilian society as a whole. Increasing number of medical doctors has been accused of criminal offenses, being more often sentenced to real terms of imprisonment, showing a clear tendency to increase gravity of responsibility applied to medical doctors. This publication represents a peer-reviewed response of paramount importance to the book by A.A. Ponkina and I.V. Ponkin «Defects in the provision of medical care» raising ontological, value and technical issues for negative outcome of medical care – by the fault or in the absence of the fault of the doctor. The book puts the scientific basis beneath changes so much awaited by the Russian public health in relation to medical doctors, their social importance, objective limitlessness of their opportunities and capabilities in curing sick people and saving their lives.

Application of the QFD-fuzzy-SERVQUAL methodology as a quality planning tool at the surgical centre of a public teaching hospital

Background In Brazil, many public hospitals face constant problems related to high demand vis-à-vis an overall scarcity of resources, which hinders the operations of different sectors such as the surgical centre, as it is considered one of the most relevant pillars for the proper hospital functioning, due to its complexity, criticality as well as economic and social importance. Proper asset management based on well-founded decisions is, therefore, a sine-qua-non condition for addressing such demands. However, subjectivity and other difficulties present in decisions make the management of hospital resources a constant challenge. Methods Thus, the present work proposes the application of a hybrid approach, formed by the QFD tools, fuzzy logic and SERVQUAL as a decision support tool for the quality planning of the surgical centre of the Onofre Lopes Teaching Hospital (Hospital Universitário Onofre Lopes—HUOL). To accomplish such objective, it was necessary to discover and analyse the main needs of the medical team working in the operating room, through the application of the SERVQUAL questionnaire, associated with fuzzy logic. Results Then, the most relevant deficiencies were transformed into entries for the QFD-fuzzy, where they were translated into project requirements. Soon after, the analysis of the existing relationships between the inputs and these requirements was carried out, generating the ranking of actions with the greatest impact on the improvement of the surgical centre overall quality. Conclusions As a result, it was found that the proposed methodology can optimize the decision process to which hospital managers are submitted, improving the surgical centre operation efficiency.

Self-Employment or Selfless Employment? Exploration of Factors that Motivate, Facilitate, and Constrain Latina Entrepreneurship from a Family Embeddedness Perspective

As the economic and social importance of Latina-owned businesses continues to grow, research is needed on the factors that motivate entrepreneurship among Latinas and that facilitate and constrain their success. This study draws on in-depth interviews and survey data to explore the experiences of Latina entrepreneurs in Idaho, USA, from an embeddedness perspective combining family embeddedness and intersectionality frameworks to illustrate how family and social positioning affects motivations, opportunities, and access to resources. We found Latinas were motivated to start businesses by a range of interacting factors, including centrally a strong sense of responsibility to their nuclear and families of origin. Prominent family motivations included the desire to provide opportunities for younger and older generations and the need for flexibility to manage family and work obligations. Compared to their middle-class peers, working-class Latina entrepreneurs were more likely to need flexibility because they could not afford third-party care for a family member, to experience greater barriers to accessing traditional financing and professional advice, and to be more dependent on family support for their success, although not all had family-based resources upon which they could rely. Latinas struggled to fulfill traditional family role expectations and obligations while assuming the expanded responsibilities of running a business. While a central tension in their lives, this struggle provides the impetus to renegotiate and update traditional gender and family expectations as they navigate role conflict and strain.

Influence of Physical Activity and Sport on the Inclusion of People with Visual Impairment: A Systematic Review

People with visual impairment have greater difficulty in accessing physical activity and sport, and a lack of social interaction is also associated with a risk of exclusion. Work is currently being done to include people with visual impairment through physical activity and sport. However, there is a lack of studies examining the status and overall effectiveness of interventions in the pre- and post-COVID stage. This study aimed to provide solid evidence on the characteristics and effectiveness of interventions for the inclusion of people with visual impairment through physical activity and sport in order to address the need for dissemination on this topic. The bibliographic search was carried out with the words “Physical activity”, “Physical exercise”, “Sport”, “Physical training”, “visual disability”, “visual impairment” and “inclusion” in the databases PubMed, Scopus, Web of Science and Google Scholar from 2018 to 2021.The article selection process was according to the PRISMA protocol with a final selection of nine articles. The main results highlighted that the programmes improve the perception of people with disabilities, increase social skills and health and increase the social importance of people with disabilities in the social environment. Among the most generalised conclusions were the need for specialised training, the need for social inclusion and participation of people with visual impairment in their environments and increased physical activity.

The Environmental Problems of The Road of Water Black / Areal, Rural Area of Manaus / Amazonas

The implementation of paved or unpaved branches in the State of Amazonas, in addition to allowing the flow of agricultural products and connecting rural areas to urban centers, is of social importance, as it facilitates the mobility of local residents, access to the school environment and goods. family consumption. The objective of the research was to analyze the environmental problems, from the Água Preta / Areal Branch, located on the left bank of Highway AM-010 kilometer 32, to kilometer 10 of BR-174, in the rural area of ​​Manaus-Amazonas. The methodological procedures involved the field practice and the photographic record of the degradation conditions of the branch. The research allowed to diagnose that the branch intersects with eleven water courses, which are used by the residents, for water consumption, six of them they are forming upstream lakes due to lack of flow in the manholes that are inadequate and have little flow downstream, in addition to the silting caused by the eroded material of the branch and the extraction of sand. In this sense, the socioenvironmental problems present at the branch, are growing at an accelerated rate over ecosystems and residents have been losing their sense of belonging in relation to the branch, due to the lack of characterization of the landscape.

Autogenous biological restoration: clinical and social importance

The Biological Restoration technique aims to use a dental fragment as the main restorative material for the reconstruction of a fractured tooth or with an extensive carious process, which may be autogenous or homogeneous. The objective of this study is to present, through a clinical case, an autogenous biological restoration with 2-year clinical and radiographic monitoring, as an alternative method of restoring teeth with destroyed clinical crown in a 27-year-old male patient. The study was approved by the Research Ethics Committee (Number: 4.236.211). On clinical examination, it was found that tooth 16 had a temporary restoration in glass ionomer cement covering an extensive area involving the mesiopalatal cusp and the mesial crest. It was also noted that the patient had a healthy tooth 18 with no chewing function. Thus, it was proposed to make the autogenous biological restoration using tooth 18 extracted from the patient himself. Finally, after 2 years of follow-up, the restoration has good clinical applicability, showing the viability of the technique.

A comparison between lumped and distributed hydrological models for daily rainfall-runoff simulation

In Uruguay, the Santa Lucía Chico watershed has been studied in several hydrologic/hydraulic works due to its economic and social importance. However, few studies have been focused on water balance computation in this watershed. In this work, two daily rainfall-runoff models, a distributed (SWAT) and a lumped one (GR4J), were implemented at two subbasins of the Santa Lucía Chico watershed, with the aim of providing a thorough comparison for simulating daily hydrographs and identify possible scenarios in which each approach is more suitable than the other. Results showed that a distributed and complex model like SWAT performs better in watersheds characterized by anthropic interventions such as dams, which can be explicitly represented. On the other hand, for watersheds with no significant reservoirs, the use of a complex model may not be justified due to the higher effort required in modeling design, implementation, and computational cost, which is not reflected in a significant improvement of model performance.

Exploring the Ecology of Third Age Informal Language Learner Groups

This research explores the factors involved in the emergence of an independently organized Third Age informal language learner group in a community centre in Japan. The methodology applies PPCT (Process-Person-Context-Time) from Bronfenbrenner’s bioecological approach to provide a detailed perspective of the people, the environment and settings over time to show how these factors interact to construct an emergent learner group. The analysis looks at how and why this specific learner ecology emerges and ultimately, how it can benefit the Third Age and inform healthy ageing policy. The findings show that by engaging in second language learning, the participants find meaningful and active involvement in the group by creating a setting that welcomes self-expression, while balancing limiting and facilitating factors of resilience and reciprocal support, self-management, sage-ing, interest, agency, and responsibility. The result is the creation of a multilingual, multicultural, and multigenerational place of inclusion within the community. The study highlights the heterogeneity of the 3rd Age and illustrates the interplay of contexts outside of the learner group from micro to macro, individual and group resources, and the influence of the specific social time period. It also shows the social importance of creating opportunities for autonomous informal language learning settings in the community while highlighting the impact of Third Age agency.
