Lipectomy as an alternative for superficialization of autologous AVF in obese patients: experience of a referral center in Amazon.

Background: The preferred vascular access for hemodialysis is a native arteriovenous fistula (AVF) because it offers the best results in the short and long terms, lower morbidity and mortality, and has additional advantages in relation to central venous catheters or arteriovenous grafts. However, obesity can present an additional challenge because of the barrier of subcutaneous cellular tissue covering the surface of the vein to be punctured. Objectives: The authors review their experience with excision of subcutaneous tissue (lipectomy) overlying upper arm cephalic vein arteriovenous fistulas in obese patients. Methods: Consecutive vascular access patients undergoing lipectomy for cannulation with difficult access because of vein depth were reviewed. Cephalic vein depth was measured by ultrasound in all cases. Results: Twenty-two patients were reviewed (15 men and 7 women), with a mean body mass index of 34.0 kg/m2 (range: 28-40 kg/m2). Mean age was 58.4 years. The mean preoperative vein depth of 7.9 mm (range: 7.0-10.0 mm) was reduced to 4.7 mm (range: 3.0-6.0 mm) (P 0.01). The mean follow-up period for patients was 13.2 months. Four patients were lost to follow-up and four died during the period due to causes unrelated to vascular access. Conclusions: Obesity should not be a limiting factor to creation of a native AVF, since lipectomy is a relatively simple option for superficialization, enabling functioning native and deep arteriovenous fistulas in obese patients.

Lipectomia como alternativa de superficialização de fístula arteriovenosa autóloga em pacientes obesos: a experiência de um centro de referência na Amazônia / Lipectomy as an alternative for superficialization of autologous AVF in obese patients: experience of a referral center in Amazon

Resumo Contexto O acesso vascular preferencial para hemodiálise é a fístula arteriovenosa nativa, pois oferece melhores resultados em curto e longo prazo, proporciona menor morbimortalidade e traz vantagens adicionais em relação aos cateteres venosos centrais ou enxertos arteriovenosos. No entanto, a obesidade pode oferecer um desafio adicional proporcionado pela barreira de tecido celular subcutâneo que recobre a superfície da veia a ser puncionada. Objetivos Demonstrar a experiência do serviço com a lipectomia em acessos autólogos em pacientes obesos. Métodos Foram revisados ​​pacientes consecutivos submetidos à lipectomia por impossibilidade ou dificuldade na punção da FAV, motivada pela acentuada profundidade da veia cefálica no antebraço ou braço. Resultados Vinte e dois pacientes foram revisados (15 homens e 7 mulheres), com índice de massa corporal médio de 34 kg/m2 (variação de 28 a 40 kg/m2). A idade média foi de 58,4 anos. O tempo médio entre a confecção do acesso e a lipectomia foi de 45,1 dias, e o tempo da intervenção até a liberação para uso nas sessões de hemodiálise oscilou de 21 a 42 dias, com média de 30,9 dias. A profundidade média pré-operatória da veia cefálica no membro foi de 7,9 mm (variação de 7,0 a 10,0 mm). Isso foi reduzido para uma profundidade média de 4,7 mm (faixa de 3,0 a 6,0 mm) (P = 0,01). O período médio de seguimento dos pacientes foi de 13,2 meses. Houve perda de seguimento em quatro pacientes e quatro óbitos no período não relacionados ao acesso vascular. Conclusões A obesidade não deve ser um fator limitante para a criação de uma FAV nativa, pois a lipectomia é uma alternativa relativamente simples de superficialização, que permite a funcionalidade de fístulas arteriovenosas nativas e profundas em obesos.

Prognostic factors for femoropopliteal vascular injuries: surgical decisions matter.

Background: Lower limbs are frequently involved in vascular trauma, but it is still not clear which factors lead to unfavorable clinical outcomes. Objectives: To determine the clinical profile of patients with femoropopliteal injuries, the trauma mechanisms, and treatment and identify which factors led to unfavorable outcomes. Methods: A retrospective study based on the medical records of patients treated from 2017 to 2021. The following data were assessed: sex, age, distance to reach the hospital, trauma mechanism, hypovolemic shock, additional injuries, treatment of vascular injuries, whether fasciotomy was needed, inappropriate intraoperative decisions, and injury severity score. Need for surgical reintervention, amputation, and death were defined as unfavorable outcomes. Univariate, bivariate, and logistic regression analyses were conducted. Results: The sample comprised 94 patients; 83% were men; mean age was 30.8 years; combined arterial and venous injuries prevailed (57.5%); and superficial femoral vessels were the most affected (61.7%). Penetrating mechanisms prevailed (80.9%). Arterial injuries were most frequently treated with venous graft (59.6%) and venous injuries underwent ligation (81.4%). In 15% of cases, inappropriate surgical decisions were detected; most often use of the ipsilateral great saphenous vein for arterial reconstruction. Unfavorable outcomes occurred in 44.7%: surgical reintervention was necessary in 21.3% and limb amputation in 25.5%, while 9.5% of the patients died. Conclusions: These injuries mainly involved young men, victims of gunshot wounds. Superficial femoral vessels were the most injured; concomitant non-vascular trauma was frequent, mainly fractures. Inappropriate surgical decisions increased the need for reinterventions by 34 times. Need for fasciotomy, presence of fracture/dislocation, blunt trauma mechanism, and popliteal artery injury increased the risk of amputation.

Fatores prognósticos em traumatismos vasculares do segmento femoropoplíteo: decisões intraoperatórias são importantes / Prognostic factors for femoropopliteal vascular injuries: surgical decisions matter

Resumo Contexto O trauma vascular acomete frequentemente os membros inferiores; entretanto, ainda há dúvidas sobre quais fatores levam a desfechos desfavoráveis. Objetivos Determinar o perfil das vítimas de traumatismo femoropoplíteo, o tratamento utilizado e fatores relacionados a desfechos desfavoráveis. Métodos Estudo retrospectivo, baseado em prontuários de pacientes operados entre 2017 e 2021. Foram analisados: sexo, idade, distância percorrida para atendimento, mecanismo de trauma, presença de choque hipovolêmico, lesões associadas, tratamento, realização de fasciotomia, decisões intraoperatórias inadequadas e índice de severidade de trauma. Necessidade de reintervenção, amputação e óbito foram considerados desfechos desfavoráveis. Foram utilizadas análises univariadas, bivariadas e regressão logística. Resultados Noventa e quatro pacientes foram selecionados, sendo 83% homens, com idade média de 30,8 anos. Lesões arteriais e venosas simultâneas ocorreram em 57,5% dos casos; vasos femorais superficiais foram mais acometidos (61,7%), e mecanismos penetrantes, mais prevalentes (80,9%). Lesões arteriais foram frequentemente tratadas com enxerto venoso (59,6%), e lesões venosas foram submetidas à ligadura (81,4%). Em 15% houve decisões cirúrgicas inadequadas, sendo o uso da safena magna ipsilateral para reconstrução arterial a mais comum. Ocorreram desfechos desfavoráveis em 44,7% dos casos; em 21,3%, foi necessária reintervenção; amputação em 25,5%; e ocorreu óbito em 9,5% dos pacientes. Conclusões As lesões acometeram principalmente homens jovens, vítimas de ferimento por arma de fogo. Vasos femorais superficiais foram os mais lesados, e traumatismos não vasculares concomitantes foram frequentes, principalmente fraturas. Decisões cirúrgicas inadequadas aumentaram em 34 vezes a necessidade de reintervenções. Necessidade de realização de fasciotomia, presença de fratura/luxação, mecanismo contuso de trauma e lesão de artéria poplítea aumentaram o risco de amputação.

Incidental cardiovascular findings on chest CT scans requested for suspected COVID-19.

BACKGROUND: Computed tomography scans of the chest are often requested as a complementary examination to investigate a clinical suspicion of pulmonary disease caused by the novel coronavirus 19 (COVID-19). OBJECTIVES: Our objective was to analyze the prevalence of incidental cardiovascular findings on chest CT scans requested to assess radiological signs suggestive of COVID-19 infection. METHODS: This cross-sectional, descriptive, and retrospective study reviewed 1,444 chest tomographies conducted in the Radiology department of the Hospital de Clínicas Gaspar Vianna, from March 1 to July 30, 2020, describing the prevalence of images suggestive of viral pneumonia by COVID-19 and incidental pulmonary and cardiovascular findings. RESULTS: The mean age of the patients was 50.6 ± 16.4 years and female sex was more frequent. Computed tomography without contrast was the most frequently used method (97.2%). Aortic and coronary wall calcification and cardiomegaly were the most prevalent cardiovascular findings. CT angiography revealed aortic aneurysms (9.7%), aortic dissection (7.3%) and thoracic aortic ulcers (2.4%). CONCLUSIONS: Incidental cardiovascular findings occurred in about half of the chest CT scans of patients with suspected COVID-19, especially aortic calcifications, cardiomegaly, and coronary calcification.

Demographic and socioeconomic profiles of patients admitted with diabetic foot complications in a tertiary hospital in Belem - Para.

OBJECTIVE: to assess the socioeconomic and demographic profiles of patients hospitalized with a diagnosis of diabetic foot in a tertiary hospital in Belem-PA, Brazil, as well as to evaluate risk factors for lower limb amputations in such patients, classifying them according to the Wagner and PEDIS classifications. METHODS: we conducted a descriptive, cross-sectional, unicentric, and analytical study carried out through a structured questionnaire. RESULTS: the study consisted of 57 patients, aged between 48 and 84 years old, 66.7% being male. The average income ranged between one and three (61.4%) minimum wages and below one minimum wage (31.6%). Type II Diabetes Mellitus was predominant (86.0%). Concerning comorbidities, arterial hypertension displayed the highest proportion (62.3%), followed by dyslipidemia (52.8%). Smokers comprised 35.1% of the sample. Infectious diabetic foot (50.9%) and mixed diabetic foot (49.1%) were the most common. Of the 20 patients with previous amputation, 90% had undergone minor amputation, and 10%, major ones. Callosity (92.6%) was the most prevalent deformity. Fifty-four (94.7%) patients underwent surgery, those being debridement (24.1%), minor amputation (37.0%) and major amputation (38.9%). During hospitalization, 78.9% of individuals did not require ICU stay. Hospitalization time varied between three and 59 days, and 78.9% of hospitalized patients did not progress to death, but 43.1% of patients submitted to major amputations died. CONCLUSION: patients with diabetic foot followed-up have a low socioeconomic profile; most of them underwent surgical procedures, whether major or minor, due to the higher prevalence of infectious diabetic foot and/or non-adherence to non-operative treatment.

Development and Validation of an Application for Follow-up of Patients Undergoing Dialysis: NefroPortátil.

OBJECTIVES: To develop the NefroPortatil mobile application (app) and evaluate its effects on the management of patients undergoing dialysis. METHODS: The first stage of the work was the development, installation, and establishment of the instructions to use the phone app as an instrument to aid in the control of fluid and food intake of 52 patients undergoing dialysis. In the second stage, the patients were monitored for 3 months and evaluated using questionnaires to measure the improvement in quality of life (Kidney Disease Quality of Life Instrument) and self-management of disease (Perceived Medical Condition Self-Management Scale) by the app. In addition, laboratory tests were performed before app use and in the first, second, and third months of its use (January to April 2018). Analysis of variance was used to analyze the laboratory data, and a paired Student's t test was used to analyze the responses to the questionnaires and as a posttest (P < .05). RESULTS: Among the laboratory test results, serum phosphorus levels showed a significant difference (P < .04) after the app was used. A significant improvement was observed in self-management of the disease according to the Perceived Medical Condition Self-Management Scale questionnaire (P < .03). The usability of the app reached a median score of 9.65 from a total score of 10. CONCLUSION: The NefroPortatil app improved the degree of perception of self-care of patients undergoing dialysis with chronic kidney failure, in addition to favoring nutritional control.

Age and sex and their influence on the anatomy of the abdominal aorta and its branches.

BACKGROUND: It is not clear how patients' age and sex influence the anatomy of the aorta and its branches. OBJECTIVES: To determine the most frequent anatomical patterns of diameter and angulation of the abdominal aorta and its branches and the influence of patients' sex and age on these patterns. METHODS: CT scans with intravenous contrast from 157 patients were analyzed. Diameter and angulations of the abdominal aorta and its branches were measured in individuals of both sexes, classified into five age groups: 20 to 30 years, 31 to 40 years, 41 to 50 years, 51 to 60 years, and 61 to 70 years. Eighteen variables were analyzed: 6 arterial origin angles, 9 arterial diameters, rate of diameter enlargement, and patient's sex and age. RadiAnt 4.2.1 DICOM viewer software was used for measurements. RESULTS: The total of 157 CT scans were from 69 men and 88 women. There were statistical differences (p <0.05) in the following results: angle of origin and diameter of the superior mesenteric artery; renal artery angle and diameter; diameter of the common iliac arteries, and diameter and rate of diameter enlargement of the aorta in several segments, but not the segment immediately proximal to the celiac trunk. CONCLUSIONS: The diameters of several aorta segments and of its branches (except the left renal artery) increase progressively with age in both sexes and are larger and have a higher rate of diameter enlargement in men than in women in the same age ranges. Between sexes, the angle of origin of the superior mesenteric artery was larger in men, except between 20 and 30 years, and the angle of origin of the left renal artery was larger in women between 51 and 60 years old.

Prior exercise protects against oxidative stress and motor deficit in a rat model of Parkinson's disease.

This study investigated if a prior long-term physical exercise protocol protects the substantia nigra and the striatum against oxidative stress and motor deficits in a Parkinson Disease model induced by 6-hydroxydopamine. Three animal treatment groups were included in the study: sham; 6-hydroxydopamine and 6-hydroxydopamine/exercise. Previously to the intrastriatal lesion by 6-hydroxydopamine, rats in the exercise groups performed a swimming program for 18 weeks. The rats were submitted to behavioral tests before and after intrastriatal 6-hydroxydopamine injection. The oxidative stress was analyzed by Thiobarbituric Acid Reactive Substances and Glutathione reductase activity methods. The exercise decreased lipid peroxidation and increased glutathione reductase activity in the substantia nigra. In contrast, in the striatum, exercise increased lipid peroxidation and decreased glutathione reductase activity. Exercise increased contralateral rotations and reduces immobility levels at 14 days post lesion. The exercise prior to 6-OHDA lesion had protective action only in substantia nigra against oxidative stress.

Sexo e idade e sua influência sobre a anatomia da aorta abdominal e seus ramos / Age and sex and their influence on the anatomy of the abdominal aorta and its branches

Resumo Contexto Não se sabe ao certo como a idade e o sexo do paciente influenciam na anatomia da aorta abdominal e de seus ramos. Objetivos Determinar os padrões anatômicos (diâmetro e angulações) mais frequentes da aorta abdominal e de seus ramos e a influência do sexo e da idade dos pacientes sobre esses padrões. Métodos Foram avaliadas tomografias computadorizadas de abdome com contraste endovenoso de 157 pacientes. Foram aferidos calibre e angulação de artérias abdominais em indivíduos de ambos os sexos, agrupados em cinco faixas etárias: 20 a 30 anos, 31 a 40 anos, 41 a 50 anos, 51 a 60 anos e 61 a 70 anos. Foram analisadas 18 variáveis: seis ângulos de emergências arteriais, nove diâmetros arteriais, taxas de dilatação, sexo e faixa etária. Para a obtenção das medidas, utilizou-se o programa de computador RadiAnt 4.2.1 DICOM viewer (Medixant, Poznan, Polônia). Resultados Entre as 157 tomografias, 69 eram de homens e 88, de mulheres. Apresentaram diferença estatística (p < 0,05): ângulo de origem e diâmetro da artéria mesentérica superior; ângulo e diâmetro das artérias renais; diâmetro das artérias ilíacas comuns; diâmetro e taxa de dilatação em diversos segmentos da aorta, exceto na porção proximal ao tronco celíaco. Conclusões Os diâmetros da aorta (em diversos segmentos) e de seus ramos (exceto da artéria renal esquerda) aumentam progressivamente com o passar da idade em ambos os sexos e são maiores e possuem taxa de dilatação mais elevada em homens do que em mulheres da mesma faixa etária. Entre os sexos, o ângulo de emergência da artéria mesentérica superior foi maior em homens, exceto entre 20 e 30 anos; o ângulo de origem da artéria renal esquerda foi maior em mulheres entre 51 e 60 anos.

Modelo de Treinamento para Inserção de Dispositivos Intrauterinos / Training Model for Intrauterine Device Insertion

RESUMO Introdução Aprender praticando exclusivamente em pacientes é cada vez menos aceitável no ensino médico. O ensino baseado em simulação é uma ferramenta capaz de gerar aquisição de habilidades e competências de forma eficaz e em ambiente controlado, sem causar dano ao paciente. A Ginecologia é uma especialidade médica que depende de treinos bem estruturados, e entre os procedimentos ginecológicos destaca-se a inserção dos dispositivos intrauterinos de cobre. Para aumentar a oferta deste método contraceptivo, é preciso capacitação adequada dos profissionais de saúde. Os simuladores físicos imitam a realidade e auxiliam na aquisição de habilidades e competências, tornando de fundamental importância o ensino baseado em simulação para inserção de dispositivos intrauterinos. Objetivo Desenvolver um modelo de treinamento para aquisição de habilidades na inserção de dispositivos intrauterinos. Método Foi desenvolvido um simulador (modelo de utilidade) para inserção de dispositivos intrauterinos, composto por uma base rígida retangular com 17 cm x 15 cm x 21 cm (A x L x P), com peso de 420 gramas, confeccionada em acrinolitrilabutadieno estireno (ABS). Acoplada a este suporte, existe uma estrutura semiflexível, composta por um protótipo de canal vaginal, com colo uterino e região vulvar semelhantes à anatomia humana, confeccionada em ácido poliático flexível (PLA-FLEX). Foram selecionados 15 médicos residentes de Ginecologia e Obstetrícia para treinamento teórico-prático com o simulador proposto pelo estudo para capacitação em inserção de dispositivo intrauterino de cobre. O simulador utilizado neste estudo foi avaliado e validado por especialistas em Ginecologia e Obstetrícia. Resultados Houve melhora estatisticamente significante dos parâmetros avaliados comparando-se a avaliação inicial (pré-treinamento) e final (pós-treinamento) dos residentes, com homogeneidade no desempenho final. Na avaliação inicial, apenas 40% dos dispositivos ficaram bem posicionados, em contraste com 93,3% de sucesso de inserção após implementado o modelo de treinamento. Conclusão Desenvolveu-se um modelo de treinamento baseado em simulação que contribuiu para a aquisição de habilidades de inserção de dispositivo intrauterino de cobre quando aplicado aos residentes de Ginecologia e Obstetrícia.

ABSTRACT Introduction Learning by practicing exclusively on patients is becoming increasingly unacceptable in medical training. Simulation-based teaching is a tool capable of generating skills and competences efficiently and in a controlled environment, without causing harm to patients. Gynecology is a medical specialty that depends on well-structured training; an important gynecological procedure is the insertion of copper intrauterine devices. In order to increase the supply of this contraceptive method to the population the relevant health professionals need to be adequately trained. Physical simulators imitate reality and assist in skills acquisition. Therefore, structured training based on simulation to teach the insertion of intrauterine devices is of fundamental importance to the teaching of gynecology. Objective To develop a training model for skills acquisition for the insertion of intrauterine devices. Method A simulator (utility model) was developed for the insertion of intrauterine devices, composed of a rigid rectangular base made of acrylonitrile butadiene styrene, measuring 17 cm x 15 cm x 21 cm and weighing 420 g. Attached to this support is a semi-flexible structure made of flexible polylactic acid, composed of a prototype vaginal canal, with a uterine cervix and vulvar region, similar to the human anatomy. Fifteen gynecology and obstetrics residents were selected for theoretical and practical training with the simulator proposed by the study for the training of intrauterine copper device insertion. The simulator used in this study was evaluated by specialists in gynecology and obstetrics, who validated it for use in teaching. Results A statistically significant improvement was found in the evaluated parameters, comparing the initial evaluation and the final evaluation of the residents, whose final performances displayed homogeneity. In the initial evaluation only 40% of the devices were well positioned, in contrast to a 93.3% rate of successfull insertion following implementation of the training model.

Heart at risk: electronic educational game with information on doping in athletes / Coração em jogo: jogo eletrônico educativo na informação do doping em atletas / Corazón en juego: juego electrónico educativo en la información del doping en atletas

ABSTRACT Introduction Games are recognized tools that can be used for teaching, awareness-building and behavioral change. In the world of competitive sports, it is necessary to both educate athletes and make them aware that doping is an unsportsmanlike practice, particularly because this conduct can be life-threatening. A game called "Heart at Risk" was developed in this context for the purpose of teaching athletes which substances are characterized as doping by the World Antidoping Agency, and to raise their awareness of health hazards through entertainment. Objective Present and empirically evaluate the efficacy of the game as a tool for educating athletes on substances characterized as doping. Methods The sample group was formed by 20 players in the under-20 category of Clube do Remo (Rowing Club), aged over 18 years. The athletes underwent a pre-test, played the Heart at Risk game, and took a post-test at the end. Both tests were related to healthy sport practices (positive factors) and to doping substances (negative factors). Results Regarding the knowledge of positive factors, there was an increase of knowledge in relation to low doses of caffeine (∆ = 40%; p-value= 0.0125) and doping assessment (∆ = 55%; p-value = 0.0017). Regarding negative factors, there was an increase of knowledge in relation to diuretics (∆ = 25%; p-value = 0.0455), contaminated thermogenic (∆ = 35%; p-value = 0.0191), growth hormone-GH (∆ = 50%; p-value = 0.0025), contaminated supplements (∆ = 65%; p-value = 0.0007), and testosterone (∆ = 55%; p-value = 0.0017). Conclusion The Heart at Risk game proved to be an effective resource in the process of learning about prohibited substances and positive factors for sports performance.

The use of computed tomography for penetrating heart injury screening. / O uso da tomografia computadorizada na triagem da lesão cardíaca penetrante.

OBJECTIVE: to determine if computed tomography represents a safe option for penetrating heart injury screening. METHODS: retrospective transversal study which confronted tomographic findings with the ones detected in surgical exploration in patients that had undergone surgery because of suspected cardiac trauma from January, 2016 to January, 2018. RESULTS: seventy-two cases were analysed; 97.2% of them were males, and the most prevalent age range was 20 to 29 years; 56.9% of them presented injuries caused by firearm shots and 43.1% by cutting weapons. In 20 cases, computed tomography suggested heart injury, confirmed in 13 cases during surgery. Sensitivity of computed tomography was 56.5%, reaching a specificity of 85.7%. CONCLUSION: computed tomography must not be adopted as a routine for the screening of penetrating heart injuries.

Vascular trauma in the Amazon: updating the challenge. / Trauma vascular na Amazônia: atualizando o desafio.

OBJECTIVE: to evaluate the epidemiological data of patients operated on due to vascular trauma at a referral hospital in Pará state, to determine the variables that increase the risk of death, and to make a comparative analysis with the results previously published by the same institution. METHODS: an analytical retrospective study was performed through data collection from patients operated due to vascular injuries, between March 2013 and March 2017. Demographic and epidemiological data, such as the mechanism and topography of the lesion, distance between the trauma site and the hospital, and type of treatment and complications, were analyzed. Multivariate analysis and logistic regression studies were performed, to evaluate significant dependence between some variables and death occurrence. RESULTS: two hundred and eighty eight patients with 430 lesions were studied; 92.7% were male, 49.7% were between 25 and 49 years old; 47.2% of all injuries were caused by firearm projectiles; 47.2% of the lesions were located in the upper limbs, 42.7% in the lower limbs, 8% in the cervical region, 3.1% in the thoracic region, and 0.7% in the abdominal region; 52.8% of the patients were hospitalized for seven days or less. Amputation was required in 6.9% of patients and there was mortality in 7.93% of the cases. CONCLUSION: distances greater than 200km were associated with prolonged hospitalization and greater probability of limb amputation. Significant correlation between death occurrence and arterial injury, vascular injury in the cervical region, and vascular injury in the thoracic region was found.
