Authors: Kong Grace , Lee Juhan , Ouellette Rachel R. , Morean Meghan E.
Published: June 2024

OBJECTIVES

We assessed awareness and perceptions of, information sources about, and engagement in modifying electronic nicotine delivery systems (ENDS) among adolescents and young adults (AYAs).

METHODS

AYAs (N = 1018) endorsing past-month ENDS use completed a survey on awareness and use of the following modifications: (1) refilling rechargeable cartridges/pods or (2) disposable pods, (3) rewicking or (4) recharging disposable pods, (5) modifying nicotine e-liquids (eg, changing propylene glycol/vegetable glycerin, nicotine), (6) combining nicotine and cannabis for simultaneous vaping, and (7) putting cannabis in ENDS designed for nicotine vaping. Logistic regression assessed how sources of information (eg, friends, social media, nonsocial media Web sites, vape shops) about and perceptions of ENDS modifications associated with ENDS modifications.

RESULTS

Refilling (69.0% heard, 40.1% tried) and recharging the battery (66.4% heard, 35.8% tried) of disposable pods were most common. Friends (64.4%) and social media (46.7%) were the most common sources of information. Notable significant associations between information sources and modifications were: 1. nonsocial media Web sites and vape shops with rewicking and recharging disposable devices and modifying nicotine e-liquid; 2. nonsocial media Web sites with refilling rechargeable cartridges/pods and disposable pods; and 3. social media with recharging disposable devices and mixing nicotine and cannabis liquids. Perceptions of reduced harm and “coolness” were associated with various modifications.

DISCUSSION

AYAs are aware of and modify ENDS for purposes unintended by manufacturers. ENDS policies should consider unintended ENDS use to safeguard public health. Prevention efforts should communicate about the potential harms of ENDS modifications.
Gene—environment interaction between gaming addiction and perceived stress in late adolescents and young adults: A twin study
Authors: Hur Yoon-Mi
Published: June 2024

Background and aims

The association between perceived stress (PS) and gaming addiction (GA) is well documented. However, the mechanism for explaining this association remains unclear. Using a genetically informative design, this study aims to distinguish between the diathesis-stress and bio-ecological models of gene by environment interaction (G x E) to explain the underlying mechanism of the relationship.

Methods

In total, 1,468 twins (mean age = 22.6 ± 2.8 years) completed an online survey including the GA and PS scales. Twin correlations for GA and PS were computed and univariate model-fitting analysis was conducted to determine genetic and environmental influences on GA and PS. The bivariate G x E model-fitting analysis was performed to determine the best G x E interaction model.

Results

Additive genetic, shared environmental, and non-shared environmental effects were 0.70 (95%CI = 0.61, 0.77), 0.00, and 0.30 (95%CI = 0.26, 0.33), and 0.38 (95%CI = 0.24, 0.55), 0.35 (95% CI = 0.18, 0.51), and 0.22 (95%CI = 0.20, 0.26) for GA and PS, respectively. Bivariate G x E model-fitting analysis supported the diathesis-stress model, where genetic influences on GA were greater in higher levels of PS, whereas environmental influences on GA were small and constant across levels of PS.

Discussion and conclusions

The evidence for the diathesis-stress model for GA is consistent with the etiological process of many forms of psychopathology. The findings should be incorporated in clinical settings to improve the treatment of GA, and used in developments of intervention and prevention methods for GA.
Narrowing or in Kálmán's writings

The paper investigates the usage of the Hungarian connective vagy ‘or’. Our starting point is Ariel & Mauri's (2018, 2019) and Ariel's (2020) papers about the use of or, where they argue that its core meaning is ‘alternativity’. Our goal is to describe Hungarian vagy ‘or’ by analyzing various corpus data, and compare the results. We examined the personal subcorpus of the Hungarian National Corpus (MNSZ2), and the Hungarian Spontaneous Speech Database (BEA). In this paper, as a tribute to the memory of László Kálmán, we investigated a third corpus that is constructed from Kálmán's very popular informative texts on Qubit.
Numerical simulation and experimental study on effect of cooling rate on microstructure and strength of nanostructured materials
Authors: Nguyen Hai , Le Duc , Hoang Quyen , Quang Pham
Published: June 2024

In this study, by numerical simulation (finite element method, FEM) and experimental, the cooling rate was investigated by changing the product thickness (20, 3, 2, 1, 0.5 and 0.3) mm of Al based two-phase nanostructured materials casted through a copper mold. The effect of cooling rate on the microstructure and strength of the alloy was studied. The Experimental results showed that the precipitated intermetallic phases have a decreasing size corresponding to the increasing cooling rates by simulation from ~102 K/s to ~104 K/s. The results show that an appropriate cooling rate can improve the microstructure and properties of the alloy. The Abaqus/Standard capability for uncoupled heat transfer analysis was intended to model solid body heat conduction with general, temperature-dependent conductivity; internal energy (including latent heat effects); and quite general convection and radiation boundary conditions. This study describes the basic energy balance, constitutive models, boundary conditions, finite element discretization, and time integration procedures used. The time step used an automatic algorithm through the smallest tolerance. The maximum temperature change was allowed over a period and the increment was adjusted for this parameter, as was the rate of convergence in the non-linear cases. First-order heat transfer elements used the rule of numerical integration with integrated stations located at the corners of the element for thermal capacitance terms. (Jacobian terminology). This approach is particularly effective when there is a strong latent thermal effect. Thus, first - order elements were used in the case of latent heat. The HEATCAP element is available for single - point pooled thermal capacitance modeling. Centralized film loading options between the mold and the casting were specified by the user.

Reviewing twenty years of patents on ultrasonic-assisted pectin extraction from food and food waste
Authors: Drannikov Aleksandr A. , Di Martino Antonio , Trusova Marina E.
Published: June 2024

A growing number of alternative agro-industrial waste sources are being considered as possible sources of pectin because of the growing market demand. Pectin's multifunctionality stems from the nature of its molecule, which varies in its chemical structures, physicochemical characteristics, and possible uses based on the extraction methods and sources used. Green methods utilizing microwaves and ultrasound are becoming more popular, in addition to the traditional extraction of pectin, which relies on the use of acids and/or chelators. As a result, this review focuses on patents related to the extraction of pectin from food and food waste using ultrasound assisted technologies. The following patent databases were searched using International Patent Classification (IPC) codes and relevant keywords: PatFT-AppFT, Espace Patent Search, Information Retrieval System, Eurasian Patent Office Search, and Patentscope. Based on the analysis findings, which cover the years 2003 to 2023, 54 pertinent documents—the majority of which were issued in China—were chosen and categorized into multiple groups based on their objectives, methods for extraction intensification, and raw materials. According to the data, 2017 had the greatest number of patent registrations in the industry.

Published: June 2024

This article displays the Great Patriotic War (1941–1945) poetry of the Urals. The researched material is limited by this time interval, which is being considered from two perspectives. Firstly, in relation to the general poetic patterns of that time literature it is shown that the regional poetry is united with the all-Union poetry both from the point of view of genre painting and stylistic features (the coexistence of romantic heroic and realistic writing). Secondly, the article analyses the art of the poets who appeared to be the representatives of the three different angles of the war — the frontline — the rear — the camp. The dimension / the place taken by the individual at the state of the war affects directly the originality of the poetic perception of the war in a direct way, that is clearly proved by that period artworks of M. Lvov, L. Tatianicheva and B. Ruchiev.

Authors: TUSTUMI Francisco , PEREIRA Marina Alessandra , LISAK André Safatle , RAMOS Marcus Fernando Kodama Pertille , RIBEIRO JUNIOR Ulysses , DIAS André Roncon
Published: June 2024

ABSTRACT BACKGROUND: Predicting short- and long-term outcomes of oncological therapies is crucial for developing effective treatment strategies. Malnutrition and the host immune status significantly affect outcomes in major surgeries. AIMS: To assess the value of preoperative prognostic nutritional index (PNI) in predicting outcomes in gastric cancer patients. METHODS: A retrospective cohort analysis was conducted on patients undergoing curative-intent surgery for gastric adenocarcinoma between 2009 and 2020. PNI was calculated as follows: PNI=(10 x albumin [g/dL])+(0.005 x lymphocytes [nº/mm3]). The optimal cutoff value was determined by the receiver operating characteristic curve (PNI cutoff=52), and patients were grouped into low and high PNI. RESULTS: Of the 529 patients included, 315 (59.5%) were classified as a low-PNI group (PNI<52) and 214 (40.5%) as a high-PNI group (PNI≥52). Older age (p=0.050), male sex (p=0.003), American Society of Anesthesiologists score (ASA) III/IV (p=0.001), lower hemoglobin level (p<0.001), lower body mass index (p=0.001), higher neutrophil-lymphocyte ratio (p<0.001), D1 lymphadenectomy, advanced pT stage, pN+ and more advanced pTNM stage were related to low-PNI patient. Furthermore, 30-day (1.4 vs. 4.8%; p=0.036) and 90-day (3.3 vs. 10.5%; p=0.002) mortality rates were higher in low-PNI compared to high-PNI group. Disease-free and overall survival were worse in low-PNI patients compared to high-PNI (p<0.001 for both). ASA III/IV score, low-PNI, pT3/T4, and pN+ were independent risk factors for worse survival. CONCLUSIONS: Preoperative PNI can predict short- and long-term outcomes of patients with gastric cancer after curative gastrectomy. Low PNI is an independent factor related to worse disease-free and overall survival.

Published: June 2024

ABSTRACT BACKGROUND: Umbilical and epigastric hernias are among the most common hernias of the abdominal wall; however, there is a lack of standardization for their treatment. AIMS: To clarify the controversies regarding therapeutic possibilities, indications, and surgical techniques for umbilical and epigastric hernia repair. METHODS: A systematic review and qualitative analysis of randomized clinical trials published in the last 20 years, involving adults (aged 18 years and over) with umbilical and/or epigastric hernias, was performed by systematically searching the PubMed/Medline, Cochrane, SciELO, and LILACS databases. The risk of bias in individual studies was assessed using the Cochrane Risk of Bias Tool. RESULTS: Initially, 492 studies were selected and, subsequently, 15 randomized controlled clinical trials were chosen that met the inclusion criteria and underwent full reading and qualitative analysis, considering possible bias. CONCLUSIONS: This review concluded that it is evident the superiority of the use of meshes in the repair of epigastric/primary umbilical hernias with a defect larger than 1 cm, even in certain emergency situations. However, suture repair is a good option for patients with a defect smaller than 1 cm. In the laparoscopic approach, recent evidence points towards possible superiority in fixation with fibrin sealant, and fascial defect closure is recommended. In addition, due to a scarcity of randomized controlled trials with low risk of bias, further studies are needed on types, positioning and fixation techniques, as well as the real role of video-assisted laparoscopic surgery in the correction of hernias, especially umbilical.

ABSTRACT Lower urinary tract abnormalities are directly implicated in the etiology of renal dysfunction in 6 to 24% of dialytic patients. These patients require bladder capacity and compliance readjustment before being considered viable candidates for renal transplantation. Vesical augmentation surgeries often involve the use of intestinal segments. Although these procedures can effectively restore bladder capacity and compliance, they present various issues related to maintaining mucous absorption and secretion capacity. Acidosis, recurrent urinary tract infections, and stone formation are extremely common, leading to frequent hospitalizations and graft function loss. Urinary tissue is certainly ideal for these reconstructions; however, bladder augmentation using ureter and renal pelvis are feasible only in a minority of cases. Experimental studies have been conducted to establish the groundwork for vascularized bladder transplantation. Last year, for the first time, this procedure was performed on a brain-dead patient. During this intervention, cystectomy was performed with preservation the vascular pedicle, followed by organ reimplantation. The graft remained viable for a period of 12 hours post-transplant. However, this intervention utilized a robotic platform, making it less reproducible in a multi-organ procurement setting as well as for most transplant centers. Moreover, it is debatable whether the benefits of exclusive bladder transplantation outweigh the risks associated with immunosuppression. For patients needing renal transplantation and requiring lower urinary tract reconstruction, however, utilizing the donor’s bladder may offer an attractive alternative, avoiding the inherent complications of enterocystoplasty without increasing immunological risk. Combined kidney and bladder transplantation has the potential to emerge as the next frontier in abdominal organ transplants.

Published: June 2024

ABSTRACT BACKGROUND: Results on quality of life after inguinal hernia surgery, such as esthetics, postoperative pain, period of absence from activities, and recurrence are a relevant topic since inguinal hernia affects 27% of men and 3% of women at some point in their lives, and should guide health policies to allocate resources more efficiently. AIMS: To evaluate the quality of life in the late postoperative period of inguinal herniorrhaphy regarding recurrence, pain, esthetics, and restriction in activities, comparing the minimally invasive techniques — the transabdominal preperitoneal (TAPP) and the conventional Lichtenstein. METHODS: A cross-sectional observational clinical study was conducted with the EuraHS-QoL questionnaire validated and translated into Portuguese, applied to patients after an average of 65 months postoperatively. Forty-five patients were assessed, 28 undergoing Lichtenstein and 17 undergoing TAPP. All were males aged between 18 and 87 years with a primary unilateral inguinal hernia. Recurrent or bilateral hernias, other concomitant abdominal wall hernias, patients who chose not to participate or who were not found, and female patients were excluded from the study. RESULTS: Regarding the domains pain, restriction, and esthetics, there was no difference between the two groups when examining quality of life. Neither group presented recurrence in the studied period. CONCLUSIONS: Both TAPP and Lichtenstein techniques presented similar results concerning quality of life when compared in the long-term.

Published: June 2024

Resumo: As discussões em torno da política orçamentária discricionária têm evidenciado que seu uso agressivo pode acarretar impactos negativos no desenvolvimento econômico. Neste estudo, investigamos essa política como uma consequência de práticas rent-seeking, examinando empiricamente seu efeito sobre o orçamento público, maiormente na dimensão dos gastos na área da saúde realizados pelos municípios de Mato Grosso, durante o escândalo da “Máfia das Ambulâncias” (2001 a 2006). Nossos resultados apontam para um aumento significativo nas medidas de política orçamentária discricionária durante o caso de corrupção, principalmente entre os municípios envolvidos, sugerindo uma maior agressividade na execução do orçamento das despesas na função de saúde. Além disso, nossas descobertas destacam que o uso excessivo dessa política pode não apenas prejudicar o estado atual da economia, mas também ter impactos negativos nos indicadores de desenvolvimento social. Em suma, quanto mais os gastos públicos ultrapassam um nível ótimo, mais danos tendem a causar à saúde da população local. Essa relação entre a política orçamentária discricionária e o IFDM-Saúde foi claramente observado no contexto da “Máfia das Ambulâncias”.

RESUMO A criação de avestruz (Struthio camelus) vem sendo implantada no país, despontando como uma alternativa lucrativa na pecuária brasileira, atraindo cada vez mais o interesse de novos criadores. A necessidade do conhecimento da microflora aeróbica e anaeróbica que compõem o trato gastrintestinal destas aves, além de contribuir para a própria sanidade destes animais, seria de identificar-se possíveis portadores de microrganismos patogênicos para o homem e os animais. O presente trabalho teve por objetivos identificar as espécies de microrganismos aeróbios e anaeróbios que compõem a microbiota gastrintestinal de animais necropsiados pela disciplina de Ornitopatologia do Departamento de Clínica, Cirurgia e Reprodução Animal. Do total de 30 aves necropsiadas, de ambos os sexos e com idade varindo entre 1 dia a 3 anos de idade foram isoladas 53 amostras de Escherichia coli (61,0%), 7 de Candida spp. (8,0%), 6 de Salmonella spp. (6,9%), 5 de Morganella spp. (5,7%), 4 de Klebisiella spp. (4,6%), 3 de Providencia spp. (3,45%), 2 de Pseudomonas spp. e Staphylococcus spp. (2,3%) e 1 de Citrobacter spp., Edwarsiella tarda, Enterococcus spp., Moerella spp. e Proteus mirabilis. Da microbiota anaeróbica, foram isolados 19 amostras de Lactobacillus sp. (38%), 15 de Clostridium spp. (30%), 5 de Fusobacterium spp. (10%) e 4 de Peptoestreptococcus spp. (8%). Da mucosa do próventrículo foram identificadas 15 amostras de Candida spp. (51,7%), 6 de Lactobacillus spp. (20,7%), 5 de Aspergillus spp. (17,24%), 2 de Penicillium spp. (7%) e 1 de Staphylococcus spp. (3,45%), enquanto que da moela foram isolados 21 amostras de Candida spp. (58,3%), 9 de Aspergillus spp. (25%), 5 de Lactobacillus spp. ( 13,9%) e 1 amostra de Sthaphylococcus spp. (2,8%).

Published: June 2024

RESUMO Os nematóides entomopatogênicos (NEPs) podem ser uma ferramenta efetiva no manejo integrado de praga. No entanto, sua produção in vivo para bioensaios no laboratório ainda é difícil, necessitando que novos hospedeiros e diferentes técnicas de infecção sejam testadas para melhorar a produção. Assim, este trabalho teve por objetivo avaliar a multiplicação in vivo de 3 espécies de NEPs: Steinernema carpocapsae, Steinernema glaseri e Steinernema arenarium (Rhaditida: Steinernemaridae) em larvas de último ínstar de Galleria mellonella, Tenebrio molitor, Spodoptera frugiperda e Bombyx mori com 3 sistemas de infecção (injeção, tópica simples e composta). Assim, foi utilizado um delineamento inteiramente casualizado, em parcelas subdivididas no tempo, com um fatorial 3 x 4 na parcela (3 sistemas de infecção e 4 hospedeiros). Cada tratamento contou com 6 repetições (larvas). As maiores produções aconteceram nos primeiros 3 dias depois da emergência dos juvenis infectantes (JIs). Os tratamentos S. carpocapsae e S. arenarium tópica simples em G. mellonella apresentaram as maiores produções totais de JIs/larva, com 302.124 e 149.213, respectivamente. S. arenarium multiplicou-se por injeção em G. mellonella, mas com uma produção baixa (1.076 JIs/larva), sendo um sistema pouco eficiente para produção desta espécie. Um hospedeiro alternativo para produção in vivo é T. molitor, já que no tratamento S. arenarium tópica composta obteve-se uma produção de 103.059 JIs/larva. S. glaseri não se multiplicou em nenhum dos sistemas em T. molitor, S. frugiperda e B. mori. A multiplicação desta espécie com o sistema tópica simples em G. mellonella alcançou uma produção total de 132.065 JIs/larva. Os sistemas tópica simples e composta apresentaram as maiores produções por larva. T. molitor para a espécie S. arenarium e B. mori para S. carpocapsae apresentam boas possibilidades como hospedeiros alternativos para produção in vivo.

ABSTRACT The effect of vaccination on the serological profile of a closed Nelore beef cattle herd, endemically infected by leptospirosis was studied. Serum samples of 100% of the females (= 12 months to 8 years) were collected in Oct/1998 and examined by Microscopic Agglutination test (MAT) using 6 serovars of Leptospira spp.: icterohaemorrhagiae, canicola, pomona, grippotyphosa, hardjo and wolffi. After MAT, the animals were vaccinated and divided in 4 groups: I) hardjo/ wolffi MAT positive and vaccinated; II) hardjo/wolffi MAT positive and non-vaccinated; III) MAT negative and vaccinated and IV) MAT negative and non-vaccinated. The first vaccination was in Dec/1999 with reinforcement in Jan/2000; and revaccination in Out/2000. The 3 mL dose of a commercial vaccine containing the same 6 serovars was given subcutaneously. Serum samples were taken in Mar/2000 and Nov/2000 and examined the same way by MAT. The proportion of reagents in the 3 collections was: 62.5% (120/192), 77.4% (106/137) and 74% (91/123). Geometrical means titers were equal to 2.59, 2.34 and 2.15, respectively. Serological profile considering reagents frequency and pre-vaccination titers showed a bimodal distribution with 39.6% of negative results. After vaccination, there was an increase in the frequency of reactors, probably due to the seroconversion of negative heifers and cows, however, the vaccination did not elicit significant increase in the magnitude of the Hardjo or Wolffi titers. Instead, the geometric means in the whole herd, vaccinated and unvaccinated groups, showed a decreasing tendency. In postvaccination serological monitoring the progressive titer decrease would represent vaccine efficiency.

ABSTRACT Rotavirus is one of the most important etiological agents in infant gastroenteritis and diarrhea in neonatal animals. The purpose of this study was the optimization of isolation of rotaviruses in MA104 (fetal kidney Rhesus monkey) cells by the comparison of culture, taking into account the number of samples, different treatments with trypsin, number of serial passages, and positivity by polyacrylamide gel electrophoresis (PAGE). Twenty diarrheic fecal samples of calves and piglets from São Paulo, State, Brazil, all positive for rotavirus in ELISA and PAGE, were submitted to four isolation protocols: in treatment 1, the inoculum was left on the monolayer and the maintenance medium was trypsin-free; treatment 2 was the same as treatment 1 except that the inoculum was discarded; in treatment 3 the inoculum was left on the monolayer and the maintenance medium had 5 µg/mL of trypsin; treatment 4 was the same as the monolayer treatment 3, except that the maintenance medium had 10 µg/mL of trypsin. Fifteen samples were successfully isolated, representing an efficacy of 75% (15/20). Treatment 3 was the most suitable because the lower number of serial passages and lower cytotoxity to the cells, with statistical significance (p < 0.001) using Freedman's and Wilcoxon's tests.

Avaliou-se efeito por ingestão em Blattella germanica. Para as irradiações foi utilizado um irradiador experimental de Cobalto-60, modelo Gammacell 220. Os produtos naturais foram submetidos às doses crescentes de radiação gama: 2,5, 5,0, 7,5 e 10,0 kGy. A radiação gama aumentou a eficiência do extrato etanólico de D. pinnata com a dose de 7,5 kGy, apresentando 48,0% de eficiência sobre ninfas de B. germanica. A radiação gama apresentou efeito adverso sobre o extrato aquoso de R. graveolens, reduzindo sua eficiência de 20,0% para 2,0% nas doses de 2,5; 7,5 e 10,0 kGy e 4,0% na dose de 5,0 kGy. Com base nos resultados obtidos, a radiação gama interferiu no comportamento dos produtos naturais para o controle de pragas promovendo aumento, redução, ativação e inativação.

RESUMO Toxoplasma gondii é um protozoário de parasitismo intracelular obrigatório, capaz de infectar diversas espécies de hospedeiros vertebrados, incluindo o homem. Infecções por T. gondii manifestam-se, em geral, de forma assintomática em macacos do Velho Mundo, de forma que a suscetibilidade ao agente e a sua patogenicidade sejam similares ao que ocorre na espécie humana. O caráter oportunista do agente, assim como para a espécie humana, também se aplica ao T. gondii no caso de infecções em macacos do Velho Mundo, pois condições que favoreçam o estabelecimento de estado imunossupressivo podem predispor estes animais à toxoplasmose aguda. O presente trabalho teve como objetivo realizar a investigação sorológica para a infecção por T. gondii em macacos Rhesus mantidos em uma colônia no Município de São Paulo. Foi comparado o desempenho de duas técnicas sorológicas, a reação de imunofluorescência indireta (RIFI) e a reação de aglutinação com antígenos modificados (MAT). Dos resultados, desprende-se que a prevalência da infecção é de 17,5% e 20,0% quando determinada pelo MAT e RIFI, respectivamente. As análises estatísticas indicam inexistência de diferença entre os resultados das provas. Aspectos relacionados à ocorrência e transmissão da toxoplasmose na colônia em tela são discutidos.

RESUMO No presente trabalho, reporta-se a ocorrência do surto de DIB em frangas poedeiras, com 8 semanas de idade, 4 dias após vacinação, com vacina atenuada por baixa passagem. Os sinais clínicos foram caracterizados por manifestação de depressão, anorexia, diarréia aquosa, penas eriçadas, tremores, prostração severa e morte. Na necropsia, foram encontradas hemorragias em músculos esqueléticos e na mucosa da junção do proventrículo e moela, tumefação de rins e bursa com edema gelatinoso. As lesões histológicas da bursa consistiam em inflamação com edema interfolicular, infiltração heterofilica, congestão, hemorragia e necrose dos folículos. Este caso mostra que os sinais clínicos e lesões histológicas foram resultantes de formação de imuno-complexos semelhantes á Reação de Arthus.

RESUMO Dentre os insetos-praga que atacam as florestas de Pinus no Brasil, destaca-se o afídeo Cinara atlantica. Este, por alimentar-se sugando os ramos e caule do Pinus, acarreta perdas consideráveis. Foram feitas observações em ramos infestados, onde verificou-se alta mortalidade de C. atlantica em plantios de P. taeda, no Município de Nova Campina, SP, nos meses de junho a dezembro de 2001. Os indivíduos mortos apresentavam um crescimento micelial branco em todas as regiões intersegmentares, pronoto e cabeça. Foram feitos isolamentos em meio de cultura BDA (batatadextrose-ágar) e através de análises microscópicas foi identificado como sendo o fungo entomopatogênico Lecanicillium (= Verticillium) lecanii.

RESUMO Procurou-se avaliar o efeito de diferentes dietas larvais sobre o potencial reprodutivo de Chrysoperla raimundoi. Larvas oriundas de insetos de terceira geração multiplicados em laboratório foram alimentadas com ovos de Sitotroga cerealella e Diatraea saccharalis. Após a emergência, os adultos foram separados em casais e mantidos em gaiolas de PVC onde receberam alimento a base de lêvedo de cerveja e mel. Foi avaliado o período de pré-oviposição, a oviposição diária e total bem como, a viabilidade dos ovos produzidos por esses insetos. Com esses parâmetros, elaborouse um índice (potencial reprodutivo - PR) que leva em consideração a oviposição total (OT), a viabilidade média dos ovos (VMO) e o período de oviposição (PO). As duas dietas estudadas não promoveram diferenças significativas sobre os parâmetros avaliados. A alimentação larval composta de ovos de S. cerealella e D. saccharalis não afeta o potencial reprodutivo de C. raimundoi.

Abstract The repositories of open educational resources have been expanding in various regions of the world, which leads to the need to reflect on the role of these repositories and their implications for teaching and research in higher education, which is the objective of this study. The qualitative exploratory research was adopted as a methodological approach, to compose the literature review on the phenomenon under study, seeking to support the discussions around it. Bibliographic searches in the Scopus and Web of Science databases were used as search strategies for data collection and analysis. According to the results obtained, it became evident that open educational resources and repositories, as sources of management and dissemination of the resources, brought a new perspective to education, in the sense of openness to access, reuse, and sharing and to encourage collaborative work to adapt, transform and create new content. However, there is a need to broaden the understanding of the limitations and barriers to the sustainability and utilization of open education resource repositories and how they can contribute to innovative practices in teaching and learning, from the perspective of the users of these systems, which requires further studies with this objective.

Resumen La competencia intercultural permite que las personas sean capaces de manejar situaciones en las que se afronten estados en los que existan contradicciones y diferencias. En el contexto de menores migrantes no acompañados (MMNA) tutelados por la Administración en España, se llevó a cabo entre los años 2011 y 2022 un estudio longitudinal de tipo cuantitativo basado en el método descriptivo correlacional. El objetivo fue comprobar si el nivel de competencias interculturales de las personas que trabajan con MMNA mejora con el paso de los años, se mantiene igual o disminuye. Se realizaron comparaciones entre los datos recopilados en 2011 (n=334) y en 2022 (n=208), con la finalidad de descubrir posibles cambios entre los años establecidos. La muestra estuvo constituida por profesionales que desarrollaban su labor en centros de protección de menores de diferentes puntos de España. Los resultados manifestaron que el nivel de competencias interculturales disminuyo en relación con los resultados obtenidos en 2011. Se concluyó que seguía inalterable la necesidad de formación, lo que repercute negativamente en los procesos de inclusión de los MMNA.

Resumo A integração de emigrantes no mercado de trabalho tem efeitos na trajetória migratória da própria pessoa e na sua interação com a sociedade de acolhimento. É frequentemente trespassada por dificuldades de ajustamento do capital humano e das competências profissionais às necessidades do mercado de trabalho. A migração qualificada ilustra com particular acuidade a heterogeneidade destes processos. Com efeito, a empregabilidade da emigração qualificada não é uniforme. Alguns/mas emigrantes, embora com uma qualificação de nível superior, podem encontrar-se a desempenhar profissões não qualificadas - situação de sobre-qualificação. Com base em dois estudos sobre a emigração portuguesa, apuraram-se taxas de sobre-qualificação na ordem dos 18,1% e dos 16,9%. Identificaram-se consequências negativas desta sobre-qualificação: insatisfação com o trabalho e baixos salários. Identificaram-se também fatores associados a esta sobre-qualificação: a idade jovem, a formação em ciências sociais e humanas e a residência em países clássicos da emigração portuguesa com elevado peso de emigração pouco qualificada.
Bons encontros e Cidadania: os Sentidos Atribuídos ao Serviço de Convivência e Fortalecimento de Vínculos pelos(as) Idosos(as)

Resumo: Este artigo tem como objetivo analisar os dados produzidos por uma pesquisa qualitativa que investigou os sentidos atribuídos ao Serviço de Convivência e Fortalecimento de Vínculos (SCFV) por seus usuários(as) em Florianópolis/SC. Por meio da observação participante realizada em um SCFV durante três meses e da aplicação de uma entrevista coletiva com idosos(as), este artigo traz algumas análises sobre os processos de significação vivenciados por esses sujeitos. Apoiados na perspectiva sócio-histórica, elaboramos dois eixos de significação, que serão discutidos neste artigo: 1) Intersubjetividade e vínculo: o SCFV como “lugar acolhedor” e de “bons encontros”; 2) O(a) idoso(a) e os processos de exclusão: o SCFV como promotor da cidadania. Em termos de resultados, é possível afirmar que esse espaço se configura como um lugar importante na vida desses(as) idosos(as) – onde eles(as) se sentem acolhidos, ouvidos e reconhecidos como sujeitos. Além do fato de esse espaço ser marcado por afetos e “bons encontros”, o grupo também o revelou como um lugar potente para processos de reflexão e questionamento contra as diversas formas de segregação e violências vividas cotidianamente por ele.

Resumo: Este estudo tem o objetivo de conhecer e compreender a experiência da internação psiquiátrica parcial em Hospital-Dia sob a perspectiva de pacientes em momento que antecedeu a alta, com foco nas expectativas e no planejamento sobre esse evento. Participaram do estudo oito pessoas internadas em um Hospital-Dia que tinham a alta programada. Cada participante respondeu individualmente a uma entrevista aberta. Os dados foram analisados pelo método de Análise de Conteúdo Temática. Os participantes expressaram sentimentos ambíguos despertados pela proximidade da alta, como a insegurança de perder o apoio do serviço e a satisfação pelo fim do tratamento hospitalar. Observou-se a valorização de práticas e posturas que consideraram o paciente enquanto pessoa situada em uma história, abarcando relações afetivas, expectativas, frustrações e planos futuros. Conhecer como os pacientes vivenciam a alta contribui para que tal evento seja considerado um processo imbricado em uma experiência histórica e social, sinalizando a relevância do cuidado ampliado, longitudinal e integral.

Resumo: O diagnóstico de uma condição crônica na família tende a movimentar as relações intra e extrafamiliares. No caso do Transtorno do Espectro do Autismo (TEA), essa movimentação tende a ocorrer de forma significativa com os vínculos maternos, visto que as mães costumam ser as principais cuidadoras dos filhos com esse diagnóstico. Assim, o presente estudo objetivou investigar os impactos do diagnóstico de TEA nas redes sociais significativas maternas e como as mães lhes atribuíram sentido. Participaram 12 mães de filhos diagnosticados com TEA na infância, com as quais foram realizadas entrevistas reflexivas e construídos dois mapas de redes sociais significativas, um anterior e outro posterior ao TEA. A análise dos dados foi feita através da Grounded Theory . No momento inicial da entrevista, foi possível perceber que a maioria das participantes se referiu ao sentimento de não ter apoio, expressando desamparo. Todavia, ao longo do processo de construção dos mapas, percebeu-se relevante mudança no discurso das mães, que reconheceram e se surpreenderam com a presença de vínculos importantes nas suas redes sociais, embora, da sua perspectiva, eles não lhes proporcionem o apoio necessário. Portanto, destaca-se a importância da ativação das redes sociais significativas das mães, bem como a instrumentalização dessas redes para que possam estar presentes de maneira efetiva e fornecer apoio, salientando-se o importante papel de profissionais da saúde e da educação nesse cenário. Por fim, aponta-se o mapa de redes enquanto potente instrumento clínico e de pesquisa.
