LEVANTAMENTO FLORÍSTICO E PARÂMETROS FITOSSOCIOLÓGICOS DA RESTINGA NA LOCALIDADE DE MORRO DOS CONVENTOS, ARARANGUÁ-SC

Estudou-se a composição florística e parâmetros fitossociológicos da restinga herbácea na localidade de Morro dos Conventos, Araranguá, Santa Catarina. As restingas despertam grande interesse no meio científico por apresentarem fragilidade e grande diversidade de espécies vegetais. Para a florística utilizou-se o método expedido por caminhamento e para a fitossociologia o método de parcelas em três áreas distintas: dunas frontais, internas e baixadas, onde a vegetação é predominantemente herbácea. Foram utilizadas 20 parcelas de 2m x 2m distribuídas ao longo de um transecto de 120m, com 4m de distância entre as parcelas. A cobertura de cada espécie foi estimada pela escala de Causton. A identificação taxonômica seguiu o sistema proposto por APG IV (BYNG et al., 2016) para angiospermas. Foram registradas 15 espécies distribuídas em nove famílias botânicas. Dentre as famílias encontradas Asteraceae (6) apresentou a maior riqueza específica, seguida de Poaceae (2). Essas famílias apresentam polinização e dispersão facilitada pelo vento, que é determinante na distribuição das espécies no ambiente de dunas frontais. As espécies com maiores valores de importância foram Panicum racemosum, Hydrocotyle bonariensis, Oxypetalum tomentosum e Ipomea pes-caprae, distribuídas predominantemente nas dunas frontais, sendo que Panicum racemosum e Ipomea pes-caprae são descritas na literatura como importantes fixadoras de dunas.Palavras-chave: Restinga.

A doença periodontal como um fator agravante para a COVID-19

Recentemente, vários estudos sugeriram hipóteses para a potencial ligação inicial entre periodontite e complicações da COVID-19. Pode-se especular que um aumento nas bactérias periodontopatogênicas devido à má higiene oral agrava o quadro da COVID-19, já que as bactérias periodontopatogênicas podem influenciar na infecção por SARS-CoV-2 por aumentar a expressão de enzima conversora de angiotensina 2 (ACE2), que funcionam como um receptor para o coronavírus. Outra sugestão, que sustenta esse vínculo, são fatores de risco compartilhados, que incluem obesidade, idade, diabetes e hipertensão, entre outros. As superinfecções bacterianas são comuns em casos graves de COVID-19 e a tempestade de citocinas que ocorrem nesta doença tem muitos componentes comuns com o perfil de expressão de citocinas da doença periodontal, diante dessa semelhança observada na resposta inflamatória, podemos sugerir que há um relacionamento potencial entre COVID-19 e DP. O presente estudo  foi composto mediante a compilação de 14 (quatorze) artigos publicados, em 2020 e 2021 e tem como principal objetivo realizar um levantamento bibliográfico através de uma revisão de literatura integrativa sobre uma possível relação entre doença periodontal e COVID-19, uma vez que o conhecimento sobre a conexão, se houver, entre a microbiota oral e complicações de COVID-19, são urgentes e necessários para estabelecer a importância da higiene oral e doenças bucais pré-existentes na gravidade e risco de mortalidade de COVID-19.&nbsp

A extensão universitária frente ao isolamento social imposto pela COVID-19 / University extension front of the social isolation imposed by COVID-19

A emergência de uma nova pandemia não é uma questão de “se”, mas de “quando” irá acontecer. Atualmente, estamos diante da mais importante crise de saúde pública mundial, a pandemia do novo coronavírus. A Universidade é uma instituição criada para atender às necessidades sociais e uma das estratégias para realizar esse dever é através de ações de extensão universitária. Mas como realizar extensão universitária frente ao isolamento social imposto pelo COVID-19? Durante a pandemia a Universidade ganhou destaque em ações extensionistas, especialmente na disseminação e construção correta do conhecimento sobre SARS-CoV-2 e COVID-19, em ações que objetivam o desenvolvimento e confecção de insumos para proteção individual e coletiva, distribuídos para hospitais, profissionais de saúde e em comunidades carentes, e atividades de educação e cultura explorando novos recursos em plataformas digitais. Acreditamos no poder transformador da Universidade e no seu compromisso em reduzir impactos sociais através da extensão e que no futuro próximo a extensão deve ser enquadrada no mundo pós-pandemia

Age-Related Effects of COVID-19 Pandemic on Mechanical Reperfusion and 30-Day Mortality for STEMI : Results of the ISACS-STEMI COVID-19 Registry

Background: The constraints in the management of patients with ST-segment elevation myocardial infarction (STEMI) during the COVID-19 pandemic have been suggested to have severely impacted mortality levels. The aim of the current analysis is to evaluate the age-related effects of the COVID-19 pandemic on mechanical reperfusion and 30-day mortality for STEMI within the registry ISACS-STEMI COVID-19. Methods: This retrospective multicenter registry was performed in high-volume PPCI centers on four continents and included STEMI patients undergoing PPCI in March–June 2019 and 2020. Patients were divided according to age (< or ≥75 years). The main outcomes were the incidence and timing of PPCI, (ischemia time longer than 12 h and door-to-balloon longer than 30 min), and in-hospital or 30-day mortality. Results: We included 16,683 patients undergoing PPCI in 109 centers. In 2020, during the pandemic, there was a significant reduction in PPCI as compared to 2019 (IRR 0.843 (95%-CI: 0.825–0.861, p < 0.0001). We found a significant agerelated reduction (7%, p = 0.015), with a larger effect on elderly than on younger patients. Furthermore, we observed significantly higher 30-day mortality during the pandemic period, especially among the elderly (13.6% vs. 17.9%, adjusted HR (95% CI) = 1.55 [1.24–1.93], p < 0.001) as compared to younger patients (4.8% vs. 5.7%; adjusted HR (95% CI) = 1.25 [1.05–1.49], p = 0.013), as a potential consequence of the significantly longer ischemia time observed during the pandemic. Conclusions: The COVID-19 pandemic had a significant impact on the treatment of patients with STEMI, with a 16% reduction in PPCI procedures, with a larger reduction and a longer delay to treatment among elderly patients, which may have contributed to increase in-hospital and 30-day mortality during the pandemic

Gender Difference in the Effects of COVID-19 Pandemic on Mechanical Reperfusion and 30-Day Mortality for STEMI: Results of the ISACS-STEMI COVID-19 Registry

Background. Several reports have demonstrated the impact of the COVID-19 pandemic on the management and outcome of patients with ST-segment elevation myocardial infarction (STEMI). The aim of the current analysis is to investigate the potential gender difference in the effects of the COVID-19 pandemic on mechanical reperfusion and 30-day mortality for STEMI patients within the ISACS-STEMI COVID-19 Registry. Methods. This retrospective multicenter registry was performed in high-volume primary percutaneous coronary intervention (PPCI) centers on four continents and included STEMI patients undergoing PPCIs in March–June 2019 and 2020. Patients were divided according to gender. The main outcomes were the incidence and timing of the PPCI, (ischemia time ≥ 12 h and door-to-balloon ≥ 30 min) and in-hospital or 30-day mortality. Results. We included 16683 STEMI patients undergoing PPCIs in 109 centers. In 2020 during the pandemic, there was a significant reduction in PPCIs compared to 2019 (IRR 0.843 (95% CI: 0.825–0.861, p < 0.0001). We did not find a significant gender difference in the effects of the COVID-19 pandemic on the numbers of STEMI patients, which were similarly reduced from 2019 to 2020 in both groups, or in the mortality rates. Compared to prepandemia, 30-day mortality was significantly higher during the pandemic period among female (12.1% vs. 8.7%; adjusted HR [95% CI] = 1.66 [1.31–2.11], p < 0.001) but not male patients (5.8% vs. 6.7%; adjusted HR [95% CI] = 1.14 [0.96–1.34], p = 0.12). Conclusions. The COVID-19 pandemic had a significant impact on the treatment of patients with STEMI, with a 16% reduction in PPCI procedures similarly observed in both genders. Furthermore, we observed significantly increased in-hospital and 30-day mortality rates during the pandemic only among females. Trial registration number: NCT 04412655

Impact of Smoking Status on Mortality in STEMI Patients Undergoing Mechanical Reperfusion for STEMI : Insights from the ISACS–STEMI COVID-19 Registry

The so-called “smoking paradox”, conditioning lower mortality in smokers among STEMI patients, has seldom been addressed in the settings of modern primary PCI protocols. The ISACS– STEMI COVID-19 is a large-scale retrospective multicenter registry addressing in-hospital mortality, reperfusion, and 30-day mortality among primary PCI patients in the era of the COVID-19 pandemic. Among the 16,083 STEMI patients, 6819 (42.3%) patients were active smokers, 2099 (13.1%) previous smokers, and 7165 (44.6%) non-smokers. Despite the impaired preprocedural recanalization (p < 0.001), active smokers had a significantly better postprocedural TIMI flow compared with nonsmokers (p < 0.001); this was confirmed after adjustment for all baseline and procedural confounders, and the propensity score. Active smokers had a significantly lower in-hospital (p < 0.001) and 30-day (p < 0.001) mortality compared with non-smokers and previous smokers; this was confirmed after adjustment for all baseline and procedural confounders, and the propensity score. In conclusion, in our population, active smoking was significantly associated with improved epicardial recanalization and lower in-hospital and 30-day mortality compared with previous and non-smoking histor

Impact of chronic obstructive pulmonary disease on short-term outcome in patients with ST-elevation myocardial infarction during COVID-19 pandemic: insights from the international multicenter ISACS-STEMI registry

Background Chronic obstructive pulmonary disease (COPD) is projected to become the third cause of mortality worldwide. COPD shares several pathophysiological mechanisms with cardiovascular disease, especially atherosclerosis. However, no definite answers are available on the prognostic role of COPD in the setting of ST elevation myocardial infarction (STEMI), especially during COVID-19 pandemic, among patients undergoing primary angioplasty, that is therefore the aim of the current study. Methods In the ISACS-STEMI COVID-19 registry we included retrospectively patients with STEMI treated with primary percutaneous coronary intervention (PCI) between March and June of 2019 and 2020 from 109 high-volume primary PCI centers in 4 continents. Results A total of 15,686 patients were included in this analysis. Of them, 810 (5.2%) subjects had a COPD diagnosis. They were more often elderly and with a more pronounced cardiovascular risk profile. No preminent procedural dissimilarities were noticed except for a lower proportion of dual antiplatelet therapy at discharge among COPD patients (98.9% vs. 98.1%, P = 0.038). With regards to short-term fatal outcomes, both in-hospital and 30-days mortality occurred more frequently among COPD patients, similarly in pre-COVID-19 and COVID-19 era. However, after adjustment for main baseline differences, COPD did not result as independent predictor for in-hospital death (adjusted OR [95% CI] = 0.913[0.658-1.266], P = 0.585) nor for 30-days mortality (adjusted OR [95% CI] = 0.850 [0.620-1.164], P = 0.310). No significant differences were detected in terms of SARS-CoV-2 positivity between the two groups. Conclusion This is one of the largest studies investigating characteristics and outcome of COPD patients with STEMI undergoing primary angioplasty, especially during COVID pandemic. COPD was associated with significantly higher rates of in-hospital and 30-days mortality. However, this association disappeared after adjustment for baseline characteristics. Furthermore, COPD did not significantly affect SARS-CoV-2 positivity. Trial registration number: NCT 04412655 (2nd June 2020)
