Abstract: This study is a systematic literature review of the association between lists of potentially inappropriate medications (PIM) in clinical practice and health outcomes of older adults followed up in primary health care. For this purpose, the PRISMA protocol was used to systematize the search for articles in the PubMed, Web of Science, Scopus, Cochrane Central, LIVIVO and LILACS databases, in addition to the gray literature. Studies with randomized clinical trials were selected, using explicit criteria (lists) for the identification and management of PIM in prescriptions of older patients in primary care. Of the 2,400 articles found, six were used for data extraction. The interventions resulted in significant reductions in the number of PIM and adverse drug events and, consequently, in potentially inappropriate prescriptions (PIP) in polymedicated older adults. However, there were no significant effects of the interventions on negative clinical outcomes, such as emergency room visits, hospitalizations and death, or on improving the health status of the older adults. The use of PIM lists promotes adequate medication prescriptions for older adults in primary health care, but further studies are needed to determine the impact of reducing PIM on primary clinical outcomes.

Abstract Does French legislation encourage integration and post-national citizenship? Although French national identity and integration literature reaffirms the exhaustion of the French model and politics for integration, and although traces of economic and social segregation are still observed, data from the Institut national de la statistique et des études économiques and the Migrant Integration Policy Index indicate instead a growing care, from 2015 onwards, to include non-nationals into French society. In light of this mismatch between literature and data, this study tests the hypothesis that the legislative acts published by Paris display a propensity towards welcoming and guaranteeing rights regardless of the immigrants’ nationality. To that end, our research design is multi-method. First, we applied content analysis to 40 regulations referring to immigration, nationality, and citizenship in the period from 2001 to 2022. Then, correspondence analysis was used to gauge the correlation between the proposed categories. Corroborating our hypotheses, the results suggest that (i) French laws, decrees, and ordinances have set norms that are more focused on respecting and welcoming immigrants; and that (ii) there is a correlation between the norms that include non-nationals and those that dissociate the guarantee of rights from nationality. In this way, the present study contributes to the literature on migration flows in the 21st century, especially the guarantee of Human Rights and dignity in French society. postnational post observed care 201 onwards nonnationals non nationals society immigrants nationality end multimethod. multimethod multi method. method multi-method First 4 immigration 200 2022 Then categories hypotheses i (i laws decrees ii (ii way st century 20 202 2

Abstract Biological invasions are one of the major threats to biodiversity and good quality of life, resulting from the translocation of species by human action. There are more than 500 alien species currently invading ecosystems in Brazil, particularly plants and fishes, while little is known about invasive microorganisms. Although invasive alien species are present in all ecosystems in the country, most have been recorded in habitats with greater human interference, such as urban and peri-urban areas, farmland, dams, reservoirs, ports, and canals. Historically, the southern and southeastern regions of Brazil have had more invasive alien species, but there has been an increase in the number of invasive alien species in the central-western and northern regions in recent decades. The ornamental trade of plants and fishes as well as the illegal pet trade of wild mammals and reptiles are some of the main pathways for invasive species introduction and spread in Brazil. Breeding and cultivation systems that allow escape to natural areas are a relevant route of species introductions in freshwater ecosystems, while unintentional introductions from shipping and infrastructure are of extreme concern in marine ecosystems. The negative impacts of invasive alien species on the biota mainly include changes in community structure and local decrease in native species richness, mediated by predation, competition, and ecosystem changes. Most negative impacts are recorded for intentionally introduced species, such as fishes and plants, but unintentional introductions have led to impacts on good quality of life, with associated costs and impacts on human health. The management of biological invasions faces challenges that need to be overcome, such as the lack of public knowledge about the impact of invasive alien species, the popular appeal of charismatic invasive species or those used by humans, and the use of controversial control techniques. However, successful experiences of eradication and control in terrestrial and marine ecosystems have been recorded, some of them involving public engagement in management actions. Recognizing the issue as a cross-cutting public policy and developing ongoing governance experiences are fundamental goals for the management of invasive alien species in Brazil. life action 50 microorganisms country interference periurban peri farmland dams reservoirs ports canals Historically centralwestern central western decades richness predation competition health overcome humans techniques However actions crosscutting cross cutting 5

Resumo Invasões biológicas são uma das maiores ameaças à biodiversidade e à boa qualidade de vida, ocorrendo a partir da translocação de espécies por ação humana. Existem mais de 500 espécies exóticas invadindo ecossistemas atualmente no Brasil, com destaque para plantas e peixes. Pouco se sabe sobre microrganismos invasores. Apesar de existirem espécies exóticas invasoras em todos os ecossistemas no país, a maior parte dos registros foi feita em hábitats com maior interferência humana, como áreas urbanas, periurbanas, terras cultivadas, represas, reservatórios, portos e canais. Historicamente, as regiões sul e sudeste do Brasil apresentam mais espécies exóticas invasoras, mas nas últimas décadas se tem observado um aumento no número de espécies exóticas invasoras nas regiões centro-oeste e norte. O comércio de plantas e peixes ornamentais, assim como o comércio ilegal de mamíferos e répteis silvestres como animais de estimação são algumas das principais vias de introdução e disseminação de espécies exóticas invasoras no Brasil. Sistemas de criação e cultivo que possibilitam o escape para áreas naturais são uma relevante via de introdução em ecossistemas de águas continentais, enquanto introduções não intencionais a partir de navegação e de infraestrutura são de extrema preocupação em ecossistemas marinhos. Os impactos negativos de espécies exóticas invasoras sobre a biota incluem principalmente alterações na estrutura de comunidades e diminuição local da riqueza de espécies nativas, mediados por predação, competição e modificações ecossistêmicas. A maior parte dos impactos negativos registrados ocorreram para espécies introduzidas intencionalmente, como peixes e plantas, mas introduções não intencionais têm levado a impactos na boa qualidade de vida, com custos associados e impactos sobre a saúde humana. A gestão de invasões biológicas esbarra em desafios a serem superados, tais como a falta de conhecimento do público sobre o impacto de espécies exóticas invasoras, o apelo popular de espécies invasoras carismáticas ou utilizadas por humanos e o emprego de técnicas controversas de controle. Entretanto, experiências bem-sucedidas de erradicação e controle em ecossistemas terrestres e marinhos têm sido registrados, alguns deles envolvendo engajamento público nas ações de manejo. Reconhecer o tema como uma política pública transversal e desenvolver experiências continuadas de governança são metas fundamentais para a gestão e o manejo de espécies exóticas invasoras no Brasil. vida humana 50 invasores país urbanas periurbanas cultivadas represas reservatórios canais Historicamente centrooeste centro oeste norte ornamentais continentais nativas predação ecossistêmicas intencionalmente superados Entretanto bemsucedidas bem sucedidas 5

ABSTRACT. Melon (Cucumis melo L.) is an important species in the cucurbit family with a large economic importance in the world. Two melon cultivars commercially important in Brazil are ‘Yellow’ and ‘Gaúcho’. In addition to their economic importance, these two cultivars display phenotypic differences in aroma, a major trait determining fruit quality. Volatile organic compounds (VOCs) impart the different aroma found in this fruit and their biosynthesis is associated with fatty acid and amino acid metabolism. Using RT-qPCR techniques, the expression of seven genes (CmLOX9, CmLOX18, CmBCAT1, CmArAT1, CmPDC1, CmADH1, and CmAAT1) was determined during ripening. The lipid pathway played a strong role in determining aroma composition in non-climacteric ‘Yellow’ melons. Most volatiles decreased during ripening, explaining the non-aromatic characteristic of this cultivar. In climacteric ‘Gaúcho’ melons, the amino acid pathway was the main one related to the biosynthesis of esters, which contribute to the aroma of this cultivar. Volatile products of the branched-chain amino acid pathway correlated with CmADH1 and CmAAT1 expression, demonstrating their role in volatile synthesis in this climacteric melon cultivar. In addition, CmPDC1 contributes to the formation of aldehydes at the beginning of this pathway. ABSTRACT Cucumis L. L world ‘Yellow Yellow ‘Gaúcho.

ABSTRACT Introduction: Since the reduction of healthcare-associated infections has been a focus for quality patient care, this study aimed to evaluate the surgical site infection rate of children who underwent cardiovascular surgery after implementation of ozonized water system for hand and body hygiene allied to previously implemented preventive measures. Methods: Two uniformly comparable groups of pediatric patients underwent cardiovascular surgery. Group A (187) patients were operated prior to installation of ozonized water system (March 1 to August 31, 2019), and group B (214) patients were operated after installation of ozonized water system (October 1, 2019, to March 31, 2020). Ozonized water was used for professional hand hygiene and patient body hygiene. Results: There was statistical significance for surgical site infection reduction in group B (P=0.0289), with a relative risk of 0.560 (95% confidence interval = 0.298 to 0.920), inferring the risk of being diagnosed with surgical site infections in group B was 44% less than in group A. There was no statistical significance regarding mechanical ventilation time (P=0.1998) or mortality (P=0.4457). Conclusion: Ozonized water for professional hand hygiene and patient body hygiene was an adjuvant combined with traditional preventive methods to reduce the risk of surgical site infection, although no impact on hospital stay or mortality was observed.

RESUMEN La mordida abierta se define como aquella situación de la oclusión en la que uno o más dientes superiores o inferiores, no alcanzan el plano de la oclusión por no hacer contacto con los antagonistas. El objetivo fue determinar la frecuencia de mordida abierta en niños entre 6 a 12 años de escuelas públicas de Gran Asunción. Estudio descriptivo observacional, de corte transversal que abarcó 1095 niños de ambos sexos, de 6 a 12 años, de escuelas públicas de Gran Asunción- Paraguay en el 2019 que cumplían con los criterios de inclusión. Se realizaron evaluaciones odontológicas para determinar por medio de observación la presencia de mordida abierta y los datos fueron asentados en planillas Excel para su posterior análisis. Del total de 1095 alumnos, 242 presentan mordida abierta (22,1%). El 57,8% presentó mordida abierta anterior, el 35,5% presenta mordida abierta posterior y un 6.6% mordida abierta completa. Los datos que aporta esta investigación contribuyen para implementar y promover tratamientos a edades tempranas, lo que es de vital importancia por las múltiples consecuencias negativas de este tipo de maloclusiones en el niño, debido a que no sólo afecta a la boca, sino también a la funcionalidad de todo el sistema en el cuerpo humano.

ABSTRACT Open bite is defined as that occlusion situation in which one or more upper or lower teeth do not reach the occlusion plane because they do not make contact with the antagonists. The objective was to determine the frequency of open bite in children between 6 and 12 years of public schools in Great Asunción. Descriptive observational, cross-sectional study that included 1095 boys and girls from 6 to 12 years old, from public schools in Greater Asunción-Paraguay in 2019 who met the inclusion criteria. Dental evaluations were carried out to determine the presence of open bite by observation and the data was recorded in Excel spreadsheets for later analysis. Of the total of 1095 students, 242 presented open bite (22.1%), 57.8% presented anterior open bite, 35.5% presented posterior open bite and 6.6% complete open bite. The data provided by this research contribute to implement and promote treatments at an early age, which is of vital importance due to the multiple negative consequences of this type of malocclusion in children, because it not only affects the mouth, but also the functionality of the entire system in the human body.

RESUMO Introdução: o nariz é o ponto central da face e vulnerável à ocorrência de câncer de pele não-melanoma (CPNM), com impacto potencial na aparência. O retalho frontal paramediano (RFPM) é considerado a melhor opção para o tratamento de defeitos extensos no nariz. O objetivo deste estudo é apresentar a experiência de um centro oncológico de referência no uso de RFPM para reconstrução nasal no tratamento do CPNM. Métodos: estudo retrospectivo foi desenvolvido através do levantamento de dados de prontuário de pacientes submetidos à reconstrução nasal com RFPM devido à CPNM no Instituto do Câncer do Estado de São Paulo (ICESP). Resultados: 111 pacientes foram identificados, a maioria idosos, com comorbidades e portadores de tumores iniciais (T1 e T2). O carcinoma basocelular (CBC) foi o tipo histológico predominante. Dorso e ponta foram as subunidades mais acometidas. Além da cobertura cutânea, em metade dos casos foi realizada também a reconstrução do forro ou arcabouço do nariz. Cicatrização por segunda intenção foi a técnica de escolha no fechamento da área doadora. A liberação do pedículo foi realizada predominantemente no segundo tempo cirúrgico e o tempo para finalização do tratamento teve mediana de 6 meses. Houve baixa taxa de complicações. Conclusões: o RFPM é seguro e eficaz no tratamento do CPNM nasal, mesmo em casos de elevada complexidade. O tempo total de tratamento pode ser prolongado e impactar na qualidade de vida, sendo fundamental enfatizar e discutir este aspecto com o paciente antes da cirurgia.

ABSTRACT Introduction: nose is the central point of the face and vulnerable to the occurence of non-melanoma skin cancer (NMSC), impacting on appearance. The paramedian forehead flap (PMFF) is considered the best option to treat extensive nasal defects. The objective of this study is to present the experience on PMFF for nasal reconstruction in the treatment of NMSC of a cancer referral center. Methods: retrospective study was carried out through data from medical records of patients who underwent nasal reconstruction with PMFF due to NMSC at the Cancer Institute of the State of São Paulo (ICESP). Results: 111 patients were identified, mostly ederly, with comorbidities and on initial tumors (T1 and T2). Basal cell carcinoma (BCC) was the predominant histological type. Dorsum and tip were the most affected subunitis. In addition to skin coverage, reconstruction of the lining and structural framework was also performed in half of the cases. Second intention healing was the technique of choice in closing the donor area. Pedicle division ocurred predominantly in the second operation and the median time to complete reconstruction was 6 months. There were low complication rates. Conclusions: the PMFF is safe and effective to treat nose NMSC, even in cases of high complexity. Since the treatment time can be prolonged and impact on quality of life, it is essential to emphasize and discuss this aspect with the patients before surgery.

Resumen En el presente texto se describe la nitruración iónica de una fundición nodular, con el objetivo de incrementar la dureza superficial, para mejorar su comportamiento al desgaste. La fundición nodular utilizada es ferrítica y se procesó con gases (N2 + H2) durante 5 horas, en una cámara de tratamiento construida en el Instituto de Física de la UNAM. Las muestras tratadas se caracterizaron empleando técnicas de microscopia electrónica de barrido, microscopía de fuerza atómica, microdureza y difracción de Rayos X. Se corrobora la presencia de compuestos Fe-N en la superficie del material. Se obtuvieron además modificaciones en la morfología superficial y un incremento del 30% en la microdureza.

Abstract This text describes the plasma nitriding of a ductile iron, to increase the surface hardness and improve its wear behavior. A ferritic ductile iron was used and processed with gases (N2 + H2) for 5 hours in a treatment chamber built at the UNAM Physics Institute. The treated samples were characterized using scanning electron microscopy, atomic force microscopy, microhardness and X-ray diffraction. The presence of Fe-N compounds was corroborated on the surface of the material. Modifications in surface morphology and a 30% increase in microhardness were also obtained.

ABSTRACT Objective: To characterize adolescent health care in a Family Health Unit in Olinda, Brazil. Material and Methods: The study carried out a census in a primary health unit, and results were obtained through the analysis of medical records from individuals aged 10-19 years. Data analysis was initially performed by descriptive statistics followed by association analysis using the Chi-square test or Fisher's exact test (p≤0.05). Results: Of all registered adolescents (n=895), 54% were female. However, only 36.9% (n=330) had a care record from 10 to 19 years. Regarding the frequency with which adolescents used the health service, 89.1% performed no more than three visits throughout the entire adolescence period. Almost all care provided to adolescents had curative nature (82.7%) in relation to the preventive nature (17.3%). Conclusion: The results pointed out that adolescents seek the Family Health Unit predominantly in search of curative care and that the number of consultations is reduced and far from recommendations from the Paced and Integrated Programming Guideline of the Ministry of Health, which establishes a minimum of one medical consultation and two nursing consultations per year for adolescents and young people in general.

Abstract Background: In the present study, we have tested whether specimens of the medically relevant scorpion Tityus pachyurus, collected from two climatically and ecologically different regions, differ in the biological activities of the venom. Methods: Scorpions were collected in Tolima and Huila, Colombia. Chemical profiles of the crude venom were obtained from 80 scorpions for each region, using SDS-PAGE and RP-HPLC. Assays for phospholipase A2, direct and indirect hemolytic, proteolytic, neuromuscular, antibacterial, and insecticidal activities were carried out. Results: The electrophoretic profiles of venom from the two regions showed similar bands of 6-14 kDa, 36-45 kDa, 65 kDa and 97 kDa. However, bands between 36 kDa and 65 kDa were observed with more intensity in venoms from Tolima, and a 95 kDa band occurred only in venoms from Huila. The chromatographic profile of the venoms showed differences in the intensity of some peaks, which could be associated with changes in the abundance of some components between both populations. Phospholipase A2 and hemolytic activities were not observable, whereas both venoms showed proteolytic activity towards casein. Insecticidal activity of the venoms from both regions showed significant variation in potency, the bactericidal activity was variable and low for both venoms. Moreover, no differences were observed in the neuromuscular activity assay. Conclusion: Our results reveal some variation in the activity of the venom between both populations, which could be explained by the ecological adaptations like differences in feeding, altitude and/or diverse predator exposure. However more in-depth studies are necessary to determine the drivers behind the differences in venom composition and activities.
