Abstract Introduction: Portuguese estimates point out that nearly 20% of aortic aneurysms are treated in a ruptured setting, with in-hospital mortality reaching up to 50%. Although unfractionated heparin (UFH) is routine during elective surgery, this technical point is debatable when treating ruptured aneurysms. The authors aimed to review the literature on the topic of intraoperative heparinization with UFH within the intraoperative period of ruptured aortic aneurysms. Methods: A MEDLINE and Scopus database search using the terms “unfractionated heparin," “aortic aneurysm," and “ruptured aortic aneurysm” was performed. No time or language limitations were imposed. The last search was run in July 2023. Manuscripts were considered irrespective of study design. Additional articles of scientific interest for the purpose of this non-systematic review were included by cross-referencing. Results: In the rupture setting, UFH usage rates have widely varied throughout time and geographical sites, and they are reported to be as low as 16%. Overall, the evidence of UFH in clinical practice in this scenario is limited. Notwithstanding, there is some evidence from observational studies of an increased pro-coagulant activity in this clinical scenario, favoring a theoretical physiologic benefit. A prospective, non-randomized study of 131 OSR patients found that patients treated with UFH had improved 30-day survival (84% vs 67%, P=0.001). Non-significant differences in blood product usage were noted. Therefore, societal guideline recommendations about intraoperative UFH in ruptured aortic aneurysms are often missing. Conclusion: UFH may potentially reduce death after open repair of rAAA. These findings should be carefully interpreted, as the evidence is scarce and heterogeneous and only portrays open repair.

RESUMO Objetivo: Analisar como a mídia jornalística tem descrito as questões de qualidade de vida (QV), atividade física (AF) e saúde mental (SM) de adolescentes durante a pandemia da COVID-19. Métodos: Trata-se de um estudo descritivo e qualitativo que utilizou a análise de conteúdo. Foram analisadas 62 publicações jornalísticas do total de 8.211 veiculadas pelos jornais mais lidos de cada região brasileira entre dezembro de 2019 e agosto de 2021. Resultados: Os resultados foram agrupados e avaliados em três categorias: QV (n=11), AF (n=9) e SM (n=42). No período analisado as publicações jornalísticas sugerem que os adolescentes apresentaram maior tempo de exposição a telas, contribuindo para uma alimentação inadequada, diminuição da AF e prejuízos na QV. A pandemia também contribuiu com aumento da ansiedade, depressão, solidão e medo resultantes da desorganização mental e emocional causada pela mudança abrupta de rotina. A vulnerabilidade social apresentou-se como um fator agravante nesse contexto. As mídias jornalísticas não deram a atenção necessária aos adolescentes no que se refere às consequências negativas da pandemia na QV, AF e SM. Conclusões: As reportagens analisadas mostraram que a pandemia causou diminuição na interação social, sentimentos de incerteza, medo e o aparecimento/exacerbação de sintomas de ansiedade, estresse e depressão. A vulnerabilidade social apresentou-se como mais um obstáculo a ser enfrentado nesta problemática. Objetivo , (QV) (AF (SM COVID19.

ABSTRACT Objective: To analyze how the journalistic media has described the issues of quality of life (QoL), physical activity (PA) and mental health (MH) of adolescents during the COVID-19 pandemic. Methods: This is a descriptive and qualitative study that used content analysis. Sixty-two journalistic publications were analyzed from a total of 8211 published by the most read newspapers in each Brazilian region between December 2019 and August 2021. Results: The results were grouped and evaluated in three categories: QoL (n=11), PA (n =9) and MH (n=42). In the analyzed period, the adolescents had more time of exposure to screens, contributing to an inadequate diet, a decrease in PA and impairments in QoL. According to the media publications, the pandemic has also contributed to an increase in anxiety, depression, loneliness and fear resulting from the mental and emotional disorganization caused by the abrupt change in routine. Social vulnerability was presented as an aggravating factor in this context. The journalistic media did not pay the necessary attention to adolescents regarding the negative consequences of the pandemic on QoL, PA and MH. Conclusions: The analyzed reports showed that the pandemic caused a decrease in social interaction, feelings of uncertainty, fear and the appearance/exacerbation of symptoms of anxiety, stress and depression. Social vulnerability was presented as another obstacle to be faced in this problem.

ABSTRACT This paper presents the results of doctoral research on early childhood education in the region of Emilia-Romagna, Italy, which develops public policies that support its education system from 0 to 6 years old, in addition to progressive pedagogical practices. The research is a case study with a qualitative approach, documental analysis, and theoretical support of historical-dialectical materialism. Ten-month fieldwork was also carried out in Italy. It was concluded that the social struggle and the left-wing administrations were important for the advances in early childhood education in the region. However, the non-guarantee of the right, the duty of the State, and the free care in the 0-3 year-old range prevents access of all children to education, being the main challenge to be overcome by the government.

Abstract The thermal dynamics of the upper atmosphere, especially in the mesosphere, have been improving our understanding about the effects of climate change, as well as how the dynamics and general circulation in the upper atmosphere are driven by different types of waves, such as the atmospheric gravity waves, planetary waves and atmospheric tides. In order to study the upper atmospheric temperature variability and gravity waves, several research groups have been employing the remote technique of observing the airglow emissions originated in the upper mesosphere and lower thermosphere, besides emissions from the ionosphere. INPE’s airglow group started the studies on emissions from the upper atmosphere to investigate temperature and dynamics in the mesosphere, thermosphere/ionosphere at the end of 70’s. However, only in 2001 this group sent the first airglow experiment to the Brazilian Antarctic Station Comandante Ferraz (EACF) to measure the OH (8-3) emission and temperature. From that year to 2014, several other experiments were carried out at EACF, not only to measure the temperature and airglow intensities, but also to observe gravity waves, winds and other related phenomena. This paper presents airglow experiments at EACF from 2001 to the present, including illustrations, examples of already published results, and unpublished data. change tides thermosphere ionosphere INPEs INPE s thermosphereionosphere 70s. 70s 70 s. 70’s However 200 (EACF 83 8 3 (8-3 2014 intensities phenomena present illustrations results data 7 20 (8- 201 2 (8 (

Abstract Introduction: Renal cell carcinoma (RCC) frequently progress to involve the inferior vena cava (IVC) and even the right atrium (RA). Nephrectomy and eradication of the tumour thrombus, can extend survival and prevent symptoms of venous congestion. The authors evaluated the institutional experience of a tertiary center in the surgical management of RCC patients with tumour thrombi invading the IVC. Methods: Retrospective analysis of a single-center consecutive serie of patients with RCC and IVC tumor thrombi treated with surgery in our department between 2012 and 2021 was carried out. Demographic data, diagnostic and procedural characteristics, clinical outcomes and survival analysis were examined. Results: Of the included 18 patients, 33% (n=6) had smoking history, 78% (n=14) hypertension, 33% (n=6) diabetes and dyslipidaemia. Mean tumour size was 8.78±2.47cm (3-12cm), and 67% (n=12) of the cases were renal clear cell adenocarcinoma. On the basis of the Neves classification for IVC thrombus extension, 39% (n=7) of the patients had level I; 28% (n=5) level II; 17% (n=3) level III and 17% (n=3) level IV. The majority underwent radical nephrectomy, with cavotomy and vena cava thrombus removal followed by lateral venorrhaphy of the vena cava (89%,n=16). In one patient an infra-renal IVC ligation was performed and, in another patient, an IVC interposition with PTFE and a protesic-renal bypass were performed. In level IV, combined open sternotomy and cardiac bypass for RA thrombus control were necessary. Mean total operative time was 3h4min±1h19min and median intraoperative blood loss was 600ml requiring a median blood cells transfusion of 3.5units (0,16) during the hospital stay. Median ICU days was 2 days (0,14) and median hospital stay was 8 days (4,61). The mean preoperative serum creatinine was 1.23+0.38 mg/dL. After surgery, there was a mean decrease of serum creatinine of 0.001 mg/dL (p=.991) (paired T test), confirming the absence of renal impairment. Only one patient required reintervention in the post-operative course for splenectomy. Post-operative complications included one case of pulmonary embolism, pneumonia, acute coronary syndrome and two cases of temporary acute renal lesion. There was no 30-day mortality. Five patients underwent adjuvant chemotherapy. Median follow-up time was 19.5 months (6-46.2 months). The four-year overall survival rate was of 52.4% (figure 1). Conclusion: For advanced RCC with tumour thrombus extension into the IVC, despite the expected poor prognosis, nephrectomy and eradication of the entire tumour thrombus, has low morbidity and can prolong patient survival, in line with the presented results.

Abstract Introduction: Endovascular aneurysm repair (EVAR) offers significant advantages on aneurysm treatment. However, the management of EVAR complications or failure often results in complex surgical approaches, sometimes requiring graft explantation which remains a major challenge and one associated with a high morbidity and mortality. The purpose of this study is to review our contemporary institutional experience with EVAR explantation. Methods: An institutional administrative database was reviewed to identify patients who were subject of graft explantation following standard infra-renal EVAR between 2011 and 2021. Follow-up was extracted from patient charts. The primary endpoint was perioperative mortality (30-days or in-hospital). Demographics, indications for explantation and procedure details were evaluated. Results: Over a 10-year period, between 2011 and 2021, there were 617 standard primary EVAR procedures performed in our institution for infrarenal aortic aneurysms. During this period, we identified 13 patients submitted to EVAR explantation, two of which were referrals from other vascular centers. All patients were male and mean age at explantation was 71 years (range 47-81). The primary EVAR procedure took place 29 months (range 0-72) before explantation. The primary indication for EVAR was ruptured aortic aneurysm in seven patients. The majority of explantation operations were emergent (6/13, three due to unstable aorto-enteric fistula (AEF), three due to rupture) or urgent (4/13, two stable AEF, two graft infections). In 3 cases, explantation was elective (two type Ia endoleaks and one type II endoleak with sac expansion). None of the patients had been submitted to a previous attempt at endovascular salvage. All patients were submitted to transperitoneal approaches, and all required initial supracoeliac or suprarenal aortic clamping. After explantation, in situ reconstruction was performed in eight patients, six of which with complete EVAR explantation and two with partial EVAR explantation. Two in situ reconstructions were made using superficial femoral veins, and the remaining used prosthetic grafts. Aortic ligation and extra-anatomic bypass were performed in five cases, The 30-day mortality was 54% (seven patients) with 33% of mortality for elective repair, 50% mortality for urgent repair, and 67% mortality for emergent repair. Mean hospital stay after surgery was 48 days for survivors. Mean survival after discharge was 10 months. Conclusion: EVAR explantation is still a relatively rare and particularly complex procedure. When the reason for explantation is graft infection and AEF, and when performed in an emergent context, it is a particularly morbid procedure with a dismal prognosis. As the number of endovascular aneurysm repairs increase, our global experience will become increasingly important in bettering our surgical and clinical outcomes.

Abstract Introduction: Delayed type Ia endoleaks are often associated with proximal extension of the aneurysmal degeneration to the juxtarenal aortic segment. Endovascular treatment of type Ia endoleaks secondary to aortic neck dilatation can raise many technical challenges related to the previous implanted stent graft. Case report: The authors present a clinical case of an 84 year-old man, with a past medical history of atrial fibrillation, acute ischemic stroke, hypertension and dyslipidemia, that initially underwent an EVAR for a 5.5.cm infrarenal AAA with a TREO Bolton® endograft. After 3 years of follow-up, the CTA scan showed a delayed type Ia endoleak secondary to aortic neck dilatation with significant growth of the aneurysmatic sac. An endovascular proximal extension was planned, using a Zenith Fenestrated (ZFEN) platform (Cook Medical, Bloomington, Ind) but the short distance to the previous EVAR bifurcation did not allow the implantation of a standard 94cm CE fenestrated stent graft. To overcome this challenge, on-table modification of the fenestrated stent graft was performed by cutting the distal aortic stent. The stent graft was partially deployed on-table, the distal stent was cut with thermocautery, and the device was re-sheathed. The fenestrated cuff was then implanted in the standard fashion with target vessel catheterization and stenting. Two aortic covered stents (Aortic Begraft Bentley® 18mm) were implanted inside each iliac limb of the previous EVAR and sealed proximally in a parallel graft configuration on the fenestrated cuff. The final completion angiogram demonstrated perfusion of the visceral arteries, resolution of the Ia endoleak and without further endoleaks, as well as perfusion of both hypogastric arteries. At two months of follow up, the patient remains asymptomatic and the CTA scan showed resolution of the type Ia endoleak but the presence of a late type II endoleak. Discussion: Delayed type Ia endoleaks associated with proximal extension of the aneurysmal degeneration to the juxtarenal aortic segment, can raise some technical difficulties related to the previous implanted stent graft. Careful evaluation of patient anatomy and previous endografts should be done in planning for these procedures. On table physician modification of stent grafts is a valid solution to overcome challenging cases limitations. Further long-term follow-up is needed.

Resumo Fundamento A COVID-19 adicionou um fardo enorme sobre os médicos ao redor do mundo, especialmente as mulheres médicas, que são afetadas pelo aumento da carga de trabalho e pela perda da qualidade de vida. Objetivo Avaliar os efeitos da pandemia de COVID-19 na qualidade de vida, burnout e espiritualidade de médicas brasileiras que atendem pacientes com COVID-19 direta ou indiretamente. Método Estudo prospectivo, observacional realizado de 28 de julho a 27 de setembro de 2020, no Brasil, com mulheres médicas de 47 especialidades, a mais frequente sendo a cardiologia (22,8%), sem restrição de idade. Elas responderam voluntariamente um questionário online com questões sobre características demográficas e socioeconômicas, qualidade de vida (WHOQOL-brief) e espiritualidade (WHOQOL-SRPB) e enunciados do Oldenburg Burnout Inventory. A análise estatística utilizou o software R, regressão beta, árvores de classificação e matriz de correlação policórica, com nível de significância de 5%. Resultados Das 769 respondentes, 61,6% relataram sinais de burnout. Cerca de 64% relataram perda salarial de até 50% durante a pandemia. Algumas relataram falta de energia para as tarefas diárias, sentimentos negativos frequentes, insatisfação com a capacidade para o trabalho, e que cuidar de outras pessoas não agregava sentido às suas vidas. Os sentimentos negativos correlacionaram-se negativamente com a satisfação com a vida sexual, a satisfação com as relações pessoais e a energia para as tarefas diárias. A incapacidade de permanecer otimista em tempos de incerteza correlacionou-se positivamente com a sensação de insegurança no dia a dia e com o não reconhecimento de que cuidar de outras pessoas trouxesse sentido à vida. Conclusão O presente estudo mostrou uma alta frequência de burnout entre as médicas brasileiras que responderam ao questionário durante a pandemia de COVID-19. Apesar disso, apresentavam uma qualidade de vida relativamente boa e acreditavam que a espiritualidade trazia-lhes conforto e segurança nos momentos difíceis.

Abstract Background COVID-19 has placed a tremendous burden on physicians worldwide, especially women physicians, affected by increased workload and loss of quality of life. Objective To assess the effects of the COVID-19 pandemic on the quality of life, burnout and spirituality of Brazilian women physicians directly or indirectly providing care to COVID-19 patients. Methods Prospective, observational study performed from July 28 to September 27, 2020, in Brazil, with women physicians from 47 specialities, the most frequent being cardiology (22.8%), with no age restriction. They voluntarily answered an online survey with questions on demographic and socioeconomic characteristics, quality of life (WHOQOL-brief), spirituality (WHOQOL-SRPB), and statements from the Oldenburg Burnout Inventory. Statistical analysis used the R software, beta regression, classification trees, and polychoric correlation matrix, with a 5% of significance level. Results Of the 769 respondents, 61.6% reported signs of burnout. About 64% reported wage loss of up to 50% during the pandemic. Some reported lack of energy for daily tasks, frequent negative feelings, dissatisfaction with capability for work, and caring for others not adding meaning to their lives. Negative feelings correlated negatively with satisfaction with sexual life and personal relations, and energy for daily tasks. The inability to remain optimistic in times of uncertainty correlated positively with feeling unsafe daily and not acknowledging that caring for others brings meaning to life. Conclusion This study showed a high frequency of burnout among Brazilian women physicians who answered the survey during the COVID-19 pandemic. Nevertheless, they presented with a relatively good quality of life and believed that spirituality comforted and reassured them in hard times.

Resumo Introdução: Nas últimas duas décadas, a abordagem de tratamento de aneurisma da aorta abdominal (AAA) mudou drasticamente de cirurgia aberta para cirurgia endovascular. A diminuição de cirurgia de AAA convencional , open aneurysm repair (OAR), levanta preocupações relativamente à competência dos futuros cirurgiões vasculares para executar este procedimento complexo e de alto risco. O principal objetivo deste estudo foi avaliar as tendências de tratamento de AAA entre internos de Cirurgia Vascular, ao longo de 15 anos, a nível nacional. Métodos: Identificação dos médicos que terminaram o internato de Angiologia e Cirurgia Vascular entre 2002 e 2017, inclusive, a nível nacional e colheita dos dados através da consulta dos currículos para a prova final de conclusão do internato complementar. Foram avaliados o total de cirurgias por AAA, tanto por OAR e por EVAR e contabilizadas aquelas realizadas como 1º cirurgião. A correlação entre o número de cirurgias abertas de AAA e o ano de conclusão do internato complementar foi testada usando o coeficiente de correlação de Spearman. Resultados: Em Portugal, de 2002-2017, apesar de não se verificar variabilidade no número total de OAR realizados, verificou-se um decréscimo marcado naqueles realizados como 1º cirurgião (rho=-0,363; P<0.02). No final do internato em 2007, um interno de Cirurgia Vascular realizava em média 15 casos de OAR e em 2007 a média foi de apenas 7 casos. Por outro lado, constatou-se um aumento marcado no número total de procedimentos de EVAR (rho=0,478; P<0.02) bem como aqueles realizados como 1ºcirurgião (rho=0,540; P<0.01). Conclusão: O presente estudo revela que os internos de Cirurgia Vascular, a nível nacional, se encontram expostos a progressivamente menos casos de OAR e verifica-se uma diminuição significativa nos procedimentos de OAR como 1º cirurgião.

Abstract Introduction: Surgical site infections are associated with devastating consequences in vascular surgery patients but the data on Methicillin Resistant Staphylococcus aureus (MRSA) infection among those remains scant and conflicting. Most vascular surgery antibiotic prophylaxis assume that all patients submitted to surgery are tested prior to the intervention or that all patients with risk factors for MRSA are presumed to be colonized. However, the costs associated with testing all patients are not negligible, and most of the vascular surgery patients have risk factors for MRSA colonization. The purpose of this study was to evaluate the burden of MRSA clinical infection and its outcome and to adjust clinical practice accordingly. Methods: A retrospective analysis of clinical data from all patients with MRSA isolations that were submitted to vascular surgery in the year 2019 was conducted. The primary endpoint was in-hospital mortality. Secondary endpoints were timing of infection (pre-existent infection or post-surgical infection), need for ICU and length of hospital stay. Results: Out of 1681 patients admitted for surgery in the year 2019 in the vascular surgery ward, only 21 had clinical infection with positive MRSA isolates. All the patients had risk factors for MRSA colonization. Seventeen were admitted for PAD (Rutherford grade 5 or 6). Eight patients had post-operatory infections, whilst the remaining presented with MRSA infection prior to the intervention. Post-operatory infections ranged from superficial incisional in three patients, deep incisional in one patient, and organ/space/prosthesis infection in four patients (of the last group, two had prosthesis infection). There were five deaths, of which two were unrelated to the infection. Of the three deaths probably infection-related, all were post-operatory surgical site infections, and all were organ/space/prosthesis infections (one with prosthesis infection). There was no patient admitted to the ICU that survived. The mean hospital stay was increased by 26 days (31 days, 95% CI, 19-43). Conclusion: Infection by MRSA was less frequent than expected in our population, which may mean that colonization might be smaller than expected. Pre-operative infection was almost always related to chronic wounds and did not increase the risk of post-operative wound infection or death, contrary to post-operative infection, which seems to significantly increase mortality.

Abstract Introduction: Phlegmasia cerulea (PC) is a severe form of deep vein thrombosis. In the setting of massive venous thrombosis and severe ischemia, catheter-directed thrombolysis (CDT) or trombectomy is mandatory. We report three cases of women with PC managed with venous thrombectomy after failure of CDT. Case reports: 1: 20 years-old, with recent intake of oral contraceptive, referred with acute onset of limb swelling, pain and a cold left lower extremity associated with foot pallor, paresthesia and numbness. Doppler ultrasound revealed occlusive thrombosis of the entire deep venous system and the great saphenous vein (GSV). Anticoagulation (AC) and CDT were started. However due to increasing levels of transaminases, creatine kinase and myoglobin, CTD was stopped and venous thrombectomy was proposed. A retrievable inferior vena cava filter (IVC) was implanted and venous surgical trombectomy. The completion venography showed a Cockett compression that was treated with stenting of the left iliac vein. Thrombophilia tests were positive for anticardiolipin antibodies an hyperhomocysteinemia. At 3-years follow-up, the patient is asymptomatic and under AC. The 3-year Doppler showed normal patency for the iliac stent and a mild femoropopliteal vein insuffiency. 2: 19 year-old, taking oral contraceptives, with acute onset of PCD with acute thrombus in the left iliac, femoral, popliteal veins. CDT was started at admittance but stopped after two days because of very low values of serum fibrinogen and persistence of occlusive thrombus in the iliac vein. A retrievable IVC filter was placed and the thrombus removed with surgical thrombectomy. Phlebography showed no significant residual thrombus and no signs of compression were present. At 1 month follow-up, the patient presented without leg edema or venous claudication symptoms. Thrombophilia testing is awaited. 3: 54 year-old who presented with low back pain, worsening left leg pain and swelling with a cyanosed and colder foot. At doppler ultrasound there were monophasic arterial flow in the left leg. After exclusion of arterial embolism, the first therapeutic approach was CDT, but it was also stopped due to very low fibrinogen levels and an ineffective thrombus lysis in venography controls. After implantation of a retrievable IVC, surgical thrombectomy via femoral vein was performed, with successful thrombus removal. Venography showed Cockett syndrome and a stent was implanted. At 6 months the patient remained without major symptoms, and Doppler confirmed stent patency with non residual obstruction or venous insufficiency. Conclusion: Awareness and timely diagnosis of phlegmasia cerulea is necessary to ensure prompt intervention to prevent loss of limb. When CDT is not effective, surgical thrombectomy remains successfully alternative. Iliac venous stenting complement is also crucial to treat associated Cockett syndrome. Endovascular thrombectomy devices may be a reasonable alternative to surgical thrombectomy.

Abstract The ionospheric investigations have improved our understanding of the space weather role in the upper atmosphere conditions, particularly at higher latitudes where the geospace phenomena print their signatures. The simultaneous observations using multi-instruments have improved our knowledge of the coupling processes inside the ionosphere, and their connection with the magnetosphere and neutral atmosphere processes under the space weather phenomena. The ionosphere probing at EACF started on 1986 using an analogical very low frequency (VLF) system, and after the year 2004 using digital VLF system, global navigation satellite system (GNSS), riometers and Canadian digital ionosonde (CADI). This paper presents the different radio techniques that have been used at Brazilian Antarctic Station Comandante Ferraz (EACF) to characterize the ionospheric conditions, and the highlights of the studies using multi-instrument observations performed in the last few decades.

Resumo Introdução: As consequências psicopatológicas e na qualidade de vida da DVC podem ser significativas, particularmente nos estadios mais avançados. As perturbações da ansiedade e do humor já estão frequentemente presentes no doente que procura o cirurgião vascular por DVC. O objetivo deste estudo foi identificar e caracterizar a psicopatologia na DVC e a sua relação com a qualidade de vida. Métodos: Estudo transversal que incluiu todos os doentes observados em primeira consulta de dois cirurgiões vasculares de um hospital universitário terciário, com o diagnóstico de DVC, de Dezembro de 2019 a Janeiro de 2021. Após realização da consulta, foram aplicados 5 questionários validados na língua portuguesa: EQ-5D (Euro quality of life - 5 Dimensions), EQVAS (Euro QoL visual analogue scale), CIVIQ20 (chronic venous insufficiency questionnaire), BAI (Beck Anxiety Inventory) e BDI (Beck&apos;s Depression Inventory). Os endpoints primários foram os scores sugestivos de perturbações da ansiedade e de humor, avaliadas nos questionários BAI e BDI, respetivamente. Os endpoints secundários foram a qualidade de vida, avaliada nos questionários EQ-5D, EQVAS e CIVIQ20. Os achados foram correlacionados com a classe clínica (C) da classificação CEAP (clinical, etiological, anatomical and pathophysiological). Resultados: Foram incluídos 59 doentes. A idade mediana foi de 58 anos. 73% eram do sexo feminino. 20% realizava previamente medicação psiquiátrica. A distribuição na classificação clínica CEAP foi a seguinte: C1 7%; C2 64%; C3 10%; C4 15%; C5 2%; C6 2%. O score CIVIQ20 mediano foi de 48 e a pontuação mediana na escala EQVAS foi de 75. O score mediano BAI foi 16, com 40% dos doentes a relatarem níveis moderados ou potencialmente preocupantes de ansiedade; o score mediano BDI foi 7, com 31% dos doentes a relatarem níveis pelo menos ligeiros de depressão. Verificou-se uma correlação positiva entre a classe clínica CEAP e o score BAI (p=0,049) e o score BDI (p=0,039). Não se verificou correlação entre a classe clínica CEAP e a pontuação na EQVAS. Doentes com score CIVIQ20 superior selecionaram pontuações inferiores na EQVAS (p<0,001). Verificou-se uma correlação positiva entre o score CIVIQ20 e o score BAI (p<0,001) e o score BDI (p=0,003). Doentes com pior saúde percecionada na EQVAS apresentaram scores superiores de ansiedade (p=0,009) e de depressão (p<0,001). Verificou-se uma correlação positiva entre o score BAI e o score BDI (p=0,002). Conclusão: As perturbações da ansiedade e do humor coexistem frequentemente e são prevalentes nos doentes com DVC sintomática. A relação entre sinais clínicos graves de DVC, qualidade de vida inferior e presença de psicopatologia foi demonstrada neste trabalho, que sugere a necessidade de uma abordagem psicológica adjuvante nos doentes com DVC.

Abstract Introduction: Chronic venous disease (CVD), particularly if severe, can have significant psychopathologic consequences and major changes in quality of life. Anxiety and humor disturbances are often already present when the patient with CVD searches the vascular surgeon. This study aims to identify and characterize psychopathology in CVD and its relation with quality of life. Methods: A transversal study included all patients seen in the first appointment with two vascular surgeons of a tertiary university hospital, with the CVD diagnosis, from December 2019 to January 2021. Five Portuguese language-validated questionnaires were used: EQ-5D (Euro quality of life - 5 Dimensions), EQVAS (Euro QoL visual analogue scale), CIVIQ20 (chronic venous insufficiency questionnaire), BAI (Beck Anxiety Inventory) and BDI (Beck&apos;s Depression Inventory). The primary endpoints were anxiety and humor disturbances’ suggestive scores, evaluated on BAI and BDI questionnaires, respectively. The secondary endpoints were quality of life, evaluated on EQ-5D, EQVAS and CIVIQ20 questionnaires. The findings were correlated according to the clinical class (C) of the CEAP classification (clinical, etiological, anatomical and pathophysiological). Results: Fifty-nine patients were included. The median age was 58 years. 73% were female. 20% was under psychiatric pills. The CEAP clinical classification was as follows: C1 7%; C2 64%; C3 10%; C4 15%; C5 2%; C6 2%. The median CIVIQ20 and EQVAS scores were 48 and 75, respectively. The median BAI score was 16; 40% of the patients stated moderate or potentially worrying anxiety levels. The median BDI score was 7; 31% of the patients stated at least mild levels of depression. There was a positive correlation between the clinical class CEAP and the BAI score (p=0,049) and the BDI score (p=0,039). There was no correlation between the clinical class CEAP and the EQVAS score. The patients with higher CIVIQ20 scores have chosen lower scores on EQVAS (p<0,001). There was a positive correlation between the CIVIQ20 score and BAI score (p<0,001) and the BDI score (p=0,003). The patients with worse ascertained health on EQVAS displayed higher anxiety (p=0,009) and depression scores (p<0,001). There was a positive correlation between BAI and BDI scores (p=0,002). Conclusion: Anxiety and depression disturbances commonly coexist and are prevalent in symptomatic CVD patients. The relation between severe clinical signs of CVD, lower quality of life and the presence of psychopathology was demonstrated in this study, which suggests the need for an adjunctive psychological approach to CVD patients.

Resumo Objetivos: analisar fatores associados ao óbito neonatal de mães adolescentes. Métodos: estudo transversal de base hospitalar em instituição terciária, randomizado, com dados do Sistema de Informação sobre Nascidos Vivos (Sinasc), Sistema de Informação sobre Mortalidade (SIM) e de prontuários. A população do estudo compreendeu 1.341 adolescentes de 10 a 19 anos assistidos durante o parto na instituição entre 2012 a 2016. As variáveis independentes foram características sociodemográficas, assistenciais, relacionadas ao pré-natal, parto, nascimento e internamento do recém-nascido, além das características do bebê. Realizou-se análise de regressão logística para avaliar a associação entre óbito neonatal e variáveis explanatórias. Resultados: os fatores associados ao óbito foram municípios do interior e outros estados (OR=2,68; IC95%=1,24-5,81), índices de apgar menor que sete no 1º(OR=9,52; IC95%=4,15-21,81) e no 5º(OR=4,17; IC95%=1,53-11,34) minutos de vida e peso ao nascer menor que 999g (OR=13,37; IC95%= 3,64-49,04) e entre 1500 a 2499g (OR=3,43; IC95%= 1,37-8,58). Conclusões: o apgar e o baixo peso ao nascer se associaram ao óbito neonatal de mães adolescentes além da procedência de municípios do interior e outros estados. Estes achados mostram além de riscos clássicos, potenciais dificuldade das adolescentes em dispor de assistência nos seus lugares de residência. Para reduzir os riscos há necessidade de reorganizar a rede assistencial materno-infantil e garantir uma rede de proteção social a estas meninas.

Abstract Objectives: to analyze factors associated with neonatal death among adolescent mothers. Methods: randomized hospital-based cross-sectional study in a tertiary institution,, data from the Sistema de Informação sobre Nascidos Vivos (Sinasc), (Live Birth Information System), Sistema de Informação sobre Mortalidade (SIM) (Mortality Information System), and medical records. The study population was comprised of 1,341 adolescents aged 10-19 who had assisted childbirth at the institution between 2012 to 2016. The independent variables were sociodemographic characteristics, care, prenatal, childbirth, birth, and newborn’s hospitalization, as well as the baby’s characteristics. Logistic regression analysis was carried out to assess the association between neonatal death and explanatory variables. Results: the factors associated with death were from the countryside or other States (OR=2.68; CI95% =1.24-5.81), Apgar scores lower than 7 in the 1st (OR= 9.52; CI95% = 4.15-21.81) and the 5th (OR=4.17; CI95%=1.53-11.34) minutes of life; and birth weight less than 999g (OR=13.37; CI95% =3, 64-49.04) and between 1,500 to 2,499g (OR=3.43; CI95%=1.37-8.58). Conclusions: apgar and low birth weight were associated with the neonatal death among adolescent mothers, as well as the fact they come from the countryside and other States. These findings show, in addition to classic risks, potential difficulties for adolescents in having access to healthcare services in their hometown. To reduce the risks, there is a need for restructuring the maternal and child healthcare network and ensure a social protection network for these girls.

Resumo Introdução: A endoprótese Nellix® (Endologix Inc., Irvine CA) é composta por dois stents expansíveis por balão envolvidos por endobags preenchidos por um polímero, obliterando assim o saco aneurismático - Endovascular Aneurysm Sealing (EVAS). Inicialmente, pelas suas propriedades, foi introduzida com instruções para uso (IFU) alargadas, possibilitando a utilização em Aneurismas da Aorta Abdominal (AAA) de anatomia mais complexa. Porém, durante a experiência com esta endoprótese, foi descrito um elevado número de complicações, levando à restrição progressiva das IFU. Atualmente, o seu uso livre foi descontinuado e apenas está disponível em centros selecionados e para efeitos investigacionais. O objetivo deste estudo é reportar os resultados institucionais da utilização da endoprótese Nellix® no contexto de AAA. Material e Métodos: Realizou-se um estudo retrospectivo referente a doentes tratados a AAA utilizando a endoprótese Nellix® numa instituição terciária universitária. Foram incluídos todos os casos eletivos e urgentes, identificados através da consulta de registos clínicos da instituição. Foram excluídos casos de aneurisma toraco-abdominal. Os dados referentes às características de base, procedimento realizado, curso do internamento e seguimento pós hospitalar foram obtidos por consulta dos processos clínicos. Foram analisados como endpoints o sucesso técnico e clínico aos 30 dias, assim como complicações e intervenções secundárias a médio e longo prazo. Resultados: Entre 2015 e 2017, a esta endoprótese foi utilizada em 12 doentes, 9 homens e 3 mulheres, com média de 71(±8) anos. As comorbilidades mais frequentemente associadas foram HTA (n=12), tabagismo (n=7), cardiopatia isquémica (n=7), DAOP (n=6) e DRC (n=6). Em todos os doentes a indicação foi aneurisma primário degenerativo, com uma excepção, cuja indicação foi a presença de endoleak (EL) tipo 1a pós-EVAR prévio. Dez doentes foram submetidos a cirurgia eletiva e dois a cirurgia urgente, ambos por aneurisma sintomático. Três eram aneurismas aortoilíacos e os restantes aórticos (n=9), sendo que 3 tinham envolvimento de pelo menos uma artéria renal. Nove doentes foram submetidos a EVAS sem procedimentos complementares; os restantes a EVAS com chimney (ChEVAS) para as renais e/ou artéria mesentérica superior (n=3). O diâmetro médio pré-operatório era de 57mm (±6.5mm). Num doente tratou-se concomitantemente um aneurisma popliteu através do implante de stent coberto. Aos 30 dias verificou-se o óbito em 2 doentes submetidos a ChEVAS. As complicações mais frequentes foram Insuficiência Respiratória (n=3) e LRA com necessidade de diálise (n=3), sendo que em dois houve oclusão intencional das artérias renais (doentes com DRC terminal em pré-diálise). Neste período, houve uma reintervenção, por isquémia aguda de membro por trombose aguda de stent popliteu, tratada com sucesso com trombólise dirigida por catéter.Após os 30 dias, verificou-se o óbito em 4 doentes (sobrevivência aos 2 anos de 60%, SE=.154). As complicações verificadas foram EL tipo 1a (n=3), EL 1b (n=1) e trombose de stent aórtico (n=1). Dois doentes foram submetidos a intervenção secundária: um submetido a pontagem femoro-femoral cruzada por trombose de stent e outro a explantação protésica e reconstrução in-situ através de pontagem aorto-bifemoral. No último, verificou-se o óbito no pós-operatório precoce. Dois doentes aguardam intervenção secundária por EL tipo 1a e crescimento do saco. O diâmetro médio do saco aneurismático no último exame ou pré-intervenção secundária era 59mm (±10.6mm). O tempo médio de follow-up é de 2.3(±1.6) anos. Conclusões: Na nossa instituição, a utilização da endoprótese Nellix® está associada a elevada taxa de complicações perioperatórias e a médio prazo, com elevada taxa de complicações relacionadas com o aneurisma, sendo o EL tipo 1a a mais frequente. Apesar de atualmente o uso livre da endoprótese estar descontinuado, os doentes que foram submetidos previamente a EVAS carecem de um plano de vigilância específico e mais intensivo, para deteção e correção atempada de complicações.

Abstract Introduction: Nellix® endoprosthesis (Endologix Inc., Irvine, CA) is composed by two ballon-expandable stents surrounded by endobags, which are filled with a polymer, thus obliterating the aneurysmal sac - Endovascular Aneurysm Sealing (EVAS). Initially, due to its properties, was introduced with extended IFU, allowing the use in more complex abdominal aortic aneurysms. However, during the initial experience with this endoprosthesis, a high number of poor outcomes have been described, leading to the progressive restriction of IFU. Currently, it has been discontinued and is only available in selected centers for clinical research purposes. Our study aim to report the institutional results of the use of the Nellix® endoprosthesis in the treatment of AAA. Material and Methods: A retrospective study was designed, including patients with AAA treated with Nellix® endoprosthesis treated at a universitary tertiary care facility. Elective and urgent patients we&apos;re included, and patients we&apos;re identified through the institutional files. Thoraco-abdominal aneurysm we&apos;re excluded. Data about baseline characteristics, surgery, hospitalization course and follow-up post discharge was obtained by consulting personal clinical files. Primary endpoints are technical and clinical success at 30 days, as complications and secondary interventions at mid and long-term. Results: Between 2015 and 2017, this endoprosthesis was used in 12 patients, 9 male and 3 female, with a mean age of 71 (±8) years. The most common comorbidities associated we&apos;re hypertension (n=12), current or former tobacco use (n=7), coronary heart disease (n=7), peripheral artery disease (n=6) and chronic kidney disease (n=6) In all patients, the treatment indication was primary degenerative aneurysm, with one exception, which was the presence of type 1a EL after EVAR. Ten patients underwent elective and 2 urgent surgery due to symptomatic aneurysm. Three we&apos;re aortoiliac aneurysms and the remaining aortic aneurysms (n=9) with three having involvement of at least one renal artery. Nine patients underwent conventional EVAS; the remaining EVAS with chimney (ChEVAS) for the renal artery(ies) or superior mesenteric artery (n=3). The average preoperative diameter was 57(±6.5) mm. One patient was simultaneously submitted to endovascular repair of a popliteal artery aneurysm with covered stent. By 30 days, death occurred in 2 patients, all submitted to ChEVAS. The most common post-operative complications we&apos;re respiratory failure (n=3), AKI with dialysis (n=3), being that in two patients there was intentional covering of the renal arteries (patients with pre-dialysis CKD). In this time frame, we verified one reintervention: catheter-directed thrombolysis for acute limb ischemia due to popliteal covered stent thrombosis. After 30 days, 4 deaths occured (2 year survival 60%, SE 0.154). The most common complications were type 1a EL(n=3), type 1b EL(n=1) and aortic stent thrombosis (n=1). Two patients have already been reintervened: one submitted to femoro-femoral crossover bypass and the other to surgical endoprosthesis explantation and in situ reconstruction aortobifemoral bypass. The last was deceased in the early postoperative period. Two patients are waiting reintervention for type Ia EL and aneurysmal sac growth. The average sac diameter in last follow-up or before secondary intervention was 59(±10.6) mm. Mean follow-up time is 2,3(±1,6) years. Conclusions: In our institution, the use of Nellix® endoprosthesis is associated with a high rate of perioperative morbidity and mid to long-term aneurysm-related complications, being type Ia EL the most common. Although the free use of the endoprosthesis is currently discontinued, patients who have previously undergone EVAS lack a specific and more intensive surveillance plan for the timely detection and correction of complications.
