- Exploring the productivity and systematicity of recipient passives in Mozambican PortuguesePublication . Mevis, Alice; Silva, Augusto Soares daThis study aims to explore and provide a detailed description of the construction known as “Dative passives” or Recipient passives in the Mozambican variety of Portuguese, in the framework of Cognitive Grammar (LANGACKER, 1991, 2008) and Construction Grammar (GOLDBERG, 1995, 2006). Particular attention will be paid to the complex semantic categories of passive and ditransitive structures in order to identify which of their conceptual aspects lay behind the emergence of Recipient passives. By means of a corpus study based on the Corpus do Português (DAVIES, 2016), it will be shown that this construction is found with a wide range of verbs of transfer, thus showing increasing signs of productivity, and that the variation displayed by Mozambican Portuguese is not random but systematic, occurring in well-defined semantic contexts. Furthermore, adopting a constructional approach to the variation at hand provides a strong argument against considering Recipient passives as derived from Double Object constructions, a claim often made in the literature (GONÇALVES 1990, 1996, 2010). By doing so, this study also offers to delve deeper into the pluricentricity of Portuguese, a tendency that is furthermore bound to increase in the near future (SOARES DA SILVA, 2022).
- Marginal bone level and clinical parameter analysis comparing external hexagon and Morse taper implants: a systematic review and meta-analysisPublication . Fuda, Samuele; Martins, Bruno Gomes dos Santos; Castro, Filipe Correia de; Heboyan, Artak; Gehrke, Sergio Alexandre; Fernandes, Juliana Campos Hasse; Mello-Moura, Anna Carolina Volpi; Fernandes, Gustavo Vicentis OliveiraThe goal of this systematic review was to verify the marginal bone loss (MBL) and other clinical parameters comparing external hexagon (EH) and Morse taper (MT) implants when they were evaluated within the same study. The focused question was, “For patients (P) treated with external connection (I) or Morse taper (C) dental implants, were there differences in the marginal bone crest maintenance after at least three months in occlusal function (O)”? As for the inclusion criteria that were considered, they included clinical studies in English that compared the MBL in implants with EH and MT, with follow-up of at least three months, that were published between 2011 and 2022; as for the exclusion criteria, they included publications investigating only one type of connection that analyzed other variables and did not report results for the MBL, reports based on questionnaires, interviews, and case reports/series, systematic reviews, or studies involving patients with a significant health problem (ASA Physical Status 3 and above). The PubMed/MEDLINE, Embase, and Web of Science databases were screened, and all of the data obtained were registered in a spreadsheet (Excel®). The Jadad scale was used to assess the quality of the studies. A total of 110 articles were initially identified; 11 were considered for full-text reading. Then, six articles (four RCTs and two prospective studies) met the eligibility criteria and were included in this study. A total of 185 patients (mean age of 59.71) were observed, and the follow-up ranged from 3 months to 36 months. A total of 541 implants were registered (267 EH and 274 MT). The survival rate ranged between 96% and 100% (the average was 97.82%). The MBL was compared among all periods studied; therefore, the common assessment period was the 12-month follow-up, presenting greater MBL for EH than for MT (p < 0.001). A mean MBL of 0.60 mm (95% CI 0.43–0.78) was found after the same period. BoP was reported in 5 studies and plaque index was reported in 4 (2 with more than 30%). Deep PD was observed in three studies. High heterogeneity was observed (I2 = 85.06%). Thus, within the limitation of this review, it was possible to conclude that there is higher bone loss in EH than in MT implants when evaluating and comparing this variable within the same study. However, the results must be carefully interpreted because of this review’s limited number of clinical studies, the short assessment period, and the high heterogeneity found.
- Effectiveness and durability of a quaternary ammonium compounds-based surface coating to reduce surface contaminationPublication . Bento de Carvalho, Teresa; Barbosa, Joana Bastos; Teixeira, PaulaFoodborne diseases are of major concern as they have a significant impact on public health, both socially and economically. The occurrence of cross-contamination of food in household kitchens is a serious threat and the adoption of safe food practices is of paramount importance. This work aimed to study the effectiveness and durability of a commercial quaternary ammonium compound-based surface coating which, according to the manufacturer, retains its antimicrobial activity for 30 days, and is suitable for all types of hard surfaces for the prevention and/or control of cross-contamination. For that, its antimicrobial efficacy, killing contact time and durability on three different surfaces—polyvinyl chloride, glass, and stainless-steel—against three pathogens—Escherichia coli ATCC 25922, Acinetobacter baumannii ESB260 and Listeria monocytogenes Scott A—were tested according to the current antimicrobial treated surfaces efficacy test (ISO22196:2011). The results showed that the antimicrobial coating was effective against all pathogens with a reduction of >5.0 log CFU/cm2 in less than one minute for the three surfaces, but its durability was less than one week on all surfaces cleaned in the usual manner. Additionally, trace amounts (≤0.2 mg/kg) of the antimicrobial coating, which may migrate into food when contacting the surface, did not show cytotoxicity to human colorectal adenocarcinoma cells. The suggested antimicrobial coating has the potential to significantly reduce surface contamination, ensure surface disinfection and reduce the likelihood of cross-contamination in domestic kitchens, although it is less durable than suggested. The use of this technology in household settings is an attractive complement to the existing cleaning protocols and solutions that are already in place.
- Environment-disaster-conflict trinomial: a study of the concepts of resilience for peacebuilding in the anthropocenePublication . Andrade, Hermes de; Rosinha, Antonio PalmaAnthropocene has been considered a geological period of high risk due to the indiscriminate use of natural resources and the lifestyle taken by the world population, to the detriment of ecosystem conservation. The problem requires a transdisciplinary scientific approach due to its complexity. As a contribution to studies in the anthropocene, this article aims to add resilience to the peacebuilding and show its potential in the integrated response of the different systems or levels of analysis. This approach can find a favorable echo in the study on the levels of complexity of resilience, to mobilize and succeed in situations of disasters-conflicts. At the end, we discuss some aspects for Integrative modeling, which works as lens through which the levels at which risk and vulnerability factors can be addressed. This lens supports a holistic understanding of the individual, community or nation factors that can provide a more relevant and integrative perspective on resilience for peacebuilding in a disaster context.
- Climate change, environmental health, and challenges for nursing disciplinePublication . Santos, Omar Portela dos; Melly, Pauline; Joost, Stéphane; Verloo, HenkCurrent data and scientific predictions about the consequences of climate change are accurate in suggesting disaster. Since 2019, climate change has become a threat to human health, and major consequences on health and health systems are already observed. Climate change is a central concern for the nursing discipline, even though nursing theorists’ understanding of the environment has led to problematic gaps that impact the current context. Today, nursing discipline is facing new challenges. Nurses are strategically placed to respond to the impacts of climate change through their practice, research, and training in developing, implementing, and sustaining innovation towards climate change mitigation and adaptation. It is urgent for them to adapt their practice to this reality to become agents of change.
