What is the role of rapid diagnostic tests for COVID-19 IgM/IgG in the pre-operative period of cosmetic plastic surgery?

Introduction: The disease by the new coronavirus 2019 (COVID-19) emerged in China and spread globally with sustained worldwide transmission from human to human. The COVID-19 IgM/IgG rapid diagnostic tests performed at the time of hospital admission, before elective surgery, are among the most widely used pre-operative screening methods. Objectives: This study aims to evaluate the role of the rapid test of COVID-19 antibodies as screening in outpatients in aesthetic plastic surgery. Methods: A systematic review was carried out for studies published since December 2019, with several search terms related to the rapid antibody test for COVID-19 and SARS-CoV-2. The relevant articles were selected through the evaluation of titles and abstracts. Relevant articles have been revised. Data on the level of evidence, sensitivity, and specificity were collected. Results: The review strategy produced 409 manuscripts. A total of 357 studies were duplicated or proved to be irrelevant to the research question. Among the remaining articles, 28 were studies without precision information, and 24 were manuscripts describing precision measures. The sensitivity varied from 18.4 to 100%; the positive predictive value between 19.7 and 100%; specificity between 94 and 100%; and the negative predictive value between 20 and 100%. Conclusion: COVID-19 IgM / IgG rapid diagnostic tests may be inaccurate. We found no evidence to support the rapid antibody test COVID-19 or SARS-CoV-2 for outpatients in cosmetic plastic surgery

Domestic three-dimensional scanner and printer in patients undergoing rhinoplasty

The principles for a successful rhinoplasty include preoperative consultation and planning, as well as a comprehensive clinical analysis and defining rhinoplasty goals. Three-dimensional domestic scanning and printing have recently become available. We sought to objectively describe this method as an intraoperative aid in patients' anatomy. This method can be used trans-operatively to help surgeons compare the results of his or her technique, check adherence to the surgical plan, and improve his or her surgical decision-making. We found that the application of 3-dimensional printing had a positive effect on the treatment of patients with aesthetic nose disorders

Breast silicone explant: a multicenter longitudinal study

Introduction: Following silicone breast implant placement, some patients present symptoms described as breast implant illness and seek explant surgery. This study aims to analyze the historical symptoms and ascertain breast explant patients’ impressions at three different times: before breast implant placement while having the implants, and after the explant surgery. Methods: This survey was designed as a multicenter longitudinal observational study using an online voluntary participation questionnaire sent by e-mail. Results: 156 patients were analyzed, 84% had three or more symptoms, and 66.1% improved their symptoms after the explant (p<0.001). Before the placement of silicone, the median self-body satisfaction was 7, while with the implants, the median became 9, and after the explant surgery, the median remained up to 9 (p<0.001). Support groups on social networks helped in the decision to explant in 87.2% of the patients. Conclusion: Patients presenting symptoms after silicone placement show improvement with breast implant removal. Body self-satisfaction increases with the placement of breast implants and remains increased after their removal. Patients who undergo the explant surgery usually regret having implanted silicone; they are very satisfied with the decision to remove them and equally satisfied with the result of the breast explant surgery. Support groups on social networks were important in the decision-making of these patients

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Bariatric surgery provides benefits to obese people. Knowledge is scarce about the role of obesity in facial age. Objectives- The aim of this study is to verify whether there is a change in the perception of facial age when comparing people with morbid obesity before surgery and one year after the procedure, along with normal weight controls. Methods- Through a prospective cohort, subjects with morbid obesity were reassessed after undergoing bariatric surgery. In a transversal study, these individuals were compared to people of normal weight. Seven plastic surgeons estimated the age of each subject based solely on their photographs. The difference in each age perceived was calculated. Results- Before surgery the mean facial age perception was 40.8 years and after was 43.7 years (p = 0.004). In the control group a mean difference of -1.03 years was observed, different from morbid obesity (p = 0.045) and after bariatric surgery (p = 0.001). Men over 40 years of age, with a preoperative body mass index between 40 kg and 49.9 kg/m2, weight greater than 127.65 kg before surgery, and the percentage loss of excess weight greater than 75.13%, demonstrated greater perceived facial aging. Conclusion- Bariatric surgery produces facial aging. Morbidly obese people and individuals who have undergone bariatric surgery appear to be older than people who have always been thin.Introdu??o- A percep??o da idade facial ? um biomarcador de sa?de. A cirurgia bari?trica proporciona benef?cios para pessoas obesas. O conhecimento ? escasso acerca do papel da obesidade na idade facial. Objetivos- Verificar se existe modifica??o na percep??o da idade facial ao comparar pessoas com obesidade m?rbida antes da cirurgia e um ano ap?s a realiza??o desta, bem como controles de peso normal. M?todos- Atrav?s de uma coorte prospectiva os sujeitos com obesidade m?rbida foram reavaliados ap?s passarem pela cirurgia bari?trica. No estudo transversal estes mesmos indiv?duos foram comparados com pessoas de peso normal. Sete cirurgi?es pl?sticos presumiram a idade de cada sujeito somente atrav?s de suas fotografias. Foi calculada a diferen?a de cada idade percebida. Resultados- Antes da cirurgia a m?dia de percep??o da idade facial foi de 40,8 anos e ap?s foi de 43,7 anos (p=0,004). No Grupo controle se observou a diferen?a na percep??o da idade facial de -1,03 anos sendo diferente da obesidade m?rbida (p= 0,045) e ap?s a cirurgia (p=0,001). Homens, maiores de 40 anos, ?ndice de massa corporal pr?-operat?rio entre 40 e 49,9 kg/m2, peso maior do que 127,65 kg antes da cirurgia, perda de peso menor do que 43,15 kg e perda do percentual de excesso de peso maior do que 75,13% apresentaram maior envelhecimento facial. Conclus?o- A cirurgia bari?trica produz envelhecimento facial. Pessoas com obesidade m?rbida e indiv?duos que se submeteram a cirurgia bari?trica aparentam ter mais idade do que pessoas que sempre foram magras

Avaliação da qualidade de cicatrizes em mamoplastia de aumento por via submamária e transareolomamilar: um estudo longitudinal prospectivo Scar quality evaluation following transareolomamilar and submammary augmentation mammaplasty: a prospective longitudinal study

INTRODUÇÃO: O aumento das mamas se tornou um dos procedimentos mais realizados em Cirurgia Plástica. A cirurgia de aumento dos seios é quase inteiramente determinada por três variáveis: localização da incisão, plano de alocação da prótese e tipo de implante. Não há provas incontestáveis que apóiem a superioridade de uma combinação de opções sobre outra. O objetivo deste estudo é comparar, através da análise do cirurgião e das pacientes submetidas ao procedimento, a qualidade da cicatriz originada pela cirurgia de aumento mamário utilizando a via submamária e transareolomamilar. MÉTODO: Estudo longitudinal prospectivo para investigar pacientes submetidas a aumento mamário estético. Foi utilizada a Escala Paciente e Observador de Avaliação da Cicatriz para mensuração da qualidade cicatricial na revisão de um ano. RESULTADOS: Quarenta e nove mulheres foram submetidas a mamoplastia de aumento primária por via inframamária (22 pessoas) ou abordagem transareolomamilar (27 pessoas), em um seguimento médio de 13 meses. O grupo transareolomamilar apresentou melhores resultados na avaliação do paciente. Entre os cirurgiões, a avaliação de ambos os grupos apresentou resultados semelhantes. CONCLUSÕES: Concluímos, com base nas escalas utilizadas e nos dados clínicos obtidos, que a via transareolomamilar demonstrou qualidade superior na avaliação de pacientes. Não houve diferença estatisticamente significativa entre as duas incisões na análise dos cirurgiões. Estudos adicionais envolvendo maior número de pacientes são necessários para comparar o resultado de cada uma das incisões avaliadas.INTRODUCTION: Breast augmentation has become one of the most frequently performed procedures in Plastic Surgery. The surgery of breast augmentation is almost entirely determined by three variables: selection of incision location, pocket plane for implant placement, and appropriate implant. There is no incontrovertible evidence that supports the superiority of one combination of choices over another. The aim of this study is compare the scar quality by means of patient and surgeon opinion, in women who have undergone augmentation mammaplasty by either the inframammary or transareomamilar approach. METHODS: A prospective study investigated patients who underwent aesthetic breast augmentation. Scar testing was performed using The Patient and Observer Scar Assessment Scale when the patient returned for the 1 year revision. RESULTS: Forty nine women underwent primary augmentation mammaplasty by either the inframammary (22 persons) or transreolomamilar (27 persons) approach at an average follow-up of 13 months. The transareolomamilar showed better results in the patient's evaluation. Among the surgeons evaluation both groups showed similar results. CONCLUSIONS: We conclude, based on the scales used and the clinical data, that the transareolomamilar has demonstrated superior quality in the patient's evaluation. It was not a statistically significant difference between the two incisions in the surgeon's analysis. Additional studies involving a larger number of patients are needed to compare the scars outcome from each of the incisions evaluated
