COVID-19 Computed tomography patterns in renal replacement therapy patients / Padrões de tomografia computadorizada da COVID-19 em pacientes em terapia renal substitutiva

ABSTRACT Introduction: Lung diseases are common in patients with end stage kidney disease (ESKD), making differential diagnosis with COVID-19 a challenge. This study describes pulmonary chest tomography (CT) findings in hospitalized ESKD patients on renal replacement therapy (RRT) with clinical suspicion of COVID-19. Methods: ESKD individuals referred to emergency department older than 18 years with clinical suspicion of COVID-19 were recruited. Epidemiological baseline clinical information was extracted from electronic health records. Pulmonary CT was classified as typical, indeterminate, atypical or negative. We then compared the CT findings of positive and negative COVID-19 patients. Results: We recruited 109 patients (62.3% COVID-19-positive) between March and December 2020, mean age 60 ± 12.5 years, 43% female. The most common etiology of ESKD was diabetes. Median time on dialysis was 36 months, interquartile range = 12-84. The most common pulmonary lesion on CT was ground glass opacities. Typical CT pattern was more common in COVID-19 patients (40 (61%) vs 0 (0%) in non-COVID-19 patients, p < 0.001). Sensitivity was 60.61% (40/66) and specificity was 100% (40/40). Positive predictive value and negative predictive value were 100% and 62.3%, respectively. Atypical CT pattern was more frequent in COVID-19-negative patients (9 (14%) vs 24 (56%) in COVID-19-positive, p < 0.001), while the indeterminate pattern was similar in both groups (13 (20%) vs 6 (14%), p = 0.606), and negative pattern was more common in COVID-19-negative patients (4 (6%) vs 12 (28%), p = 0.002). Conclusions: In hospitalized ESKD patients on RRT, atypical chest CT pattern cannot adequately rule out the diagnosis of COVID-19.

RESUMO Introdução: Doenças pulmonares são comuns em pacientes com doença renal em estágio terminal (DRET), dificultando o diagnóstico diferencial com COVID-19. Este estudo descreve achados de tomografia computadorizada de tórax (TC) em pacientes com DRET em terapia renal substitutiva (TRS) hospitalizados com suspeita de COVID-19. Métodos: Indivíduos maiores de 18 anos com DRET, encaminhados ao pronto-socorro com suspeita de COVID-19 foram incluídos. Dados clínicos e epidemiológicos foram extraídos de registros eletrônicos de saúde. A TC foi classificada como típica, indeterminada, atípica, negativa. Comparamos achados tomográficos de pacientes com COVID-19 positivos e negativos. Resultados: Recrutamos 109 pacientes (62,3% COVID-19-positivos) entre março e dezembro de 2020, idade média de 60 ± 12,5 anos, 43% mulheres. A etiologia mais comum da DRET foi diabetes. Tempo médio em diálise foi 36 meses, intervalo interquartil = 12-84. A lesão pulmonar mais comum foi opacidades em vidro fosco. O padrão típico de TC foi mais comum em pacientes com COVID-19 (40 (61%) vs. 0 (0%) em pacientes sem COVID-19, p < 0,001). Sensibilidade 60,61% (40/66), especificidade 100% (40/40). Valores preditivos positivos e negativos foram 100% e 62,3%, respectivamente. Padrão atípico de TC foi mais frequente em pacientes COVID-19-negativos (9 (14%) vs. 24 (56%) em COVID-19-positivos, p < 0,001), enquanto padrão indeterminado foi semelhante em ambos os grupos (13 (20%) vs. 6 (14%), p = 0,606), e padrão negativo foi mais comum em pacientes COVID-19-negativos (4 (6%) vs. 12 (28%), p = 0,002). Conclusões: Em pacientes com DRET em TRS hospitalizados, um padrão atípico de TC de tórax não pode excluir adequadamente o diagnóstico de COVID-19.

Long-term oncological and surgical outcomes after Video Endoscopic Inguinal Lymphadenectomy (VEIL) in patients with penile cancer

ABSTRACT Objective: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). Materials and Methods: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. Results: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. Conclusion: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.

Epidemiological aspects of pediculosis by Pediculus humanus capitis (Phthiraptera: Pediculidae) in Minas Gerais: a systematic review / Aspectos epidemiológicos da pediculose por Pediculus humanus capitis (Phthiraptera: Pediculidae) em Minas Gerais: uma revisão sistemática

Abstract Background Head lice, or head pediculosis, is a parasitosis considered a serious public health problem that affects mainly resource-limited countries. Objective To describe epidemiological aspects of the pediculosis capitis in Minas Gerais, in Brazil. Method This systematic review was conducted through the standards established by the Preferred Reporting Items in Systematic Reviews and Metanalyses (PRISMA). PubMed, LILACS, and SciELO databases, as well as the gray literature, were searched. Results Nine of 1,167 studies were included, published between 1988 and 2019. These studies reported a total prevalence of parasitosis that ranged from 1.4% to 57.4%. The prevalence of head lice ranged from 0.0% to 66.7% for males and 2.3% to 57.4% for females, thus being higher in black-skinned people (1.4% to 40.3%). Regarding age, the highest prevalence was 10-12 years old (45.3%). As for the characteristics of the hair, there was a greater infestation in people with long (16.0% to 79.5%), wavy (0.0% to 44.7%), dark (0.0% to 36.6%), with low capillary density (35.4%), and thick hair (39.2%). Conclusion Head pediculosis affects both sexes, different ages, and races, representing an important health problem in Minas Gerais, not only due to the presence of ectoparasite but also to the secondary complications that can be generated from this parasitism.

Effects of public health emergencies of international concern on disease control: a systematic review / Efectos de las emergencias de salud pública de importancia internacional en el control de enfermedades: revisión sistemática / Efeitos das emergências de saúde pública de importância internacional no controle de doenças: revisão sistemática

ABSTRACT Objectives. To assess the accumulated knowledge of the effects of public health emergencies of international concern on disease control and local health systems, and contribute to a better understanding of their effects on health programs and systems. Methods. This was a systematic review of published and gray literature (in English, Portuguese, or Spanish). Electronic databases (BVS/LILACS, PubMed, and SciELO) and Google Scholar were searched. Search terms were: COVID-19 OR H1N1 OR Ebola OR Zika OR poliomyelitis AND (outbreaks OR epidemics) AND (public health systems OR public health surveillance). Results. A total of 3 508 studies were retrieved, of which 31 met the inclusion criteria. The studies addressed the effects of the emergencies on: communicable diseases notification systems; malaria, HIV/AIDS, tuberculosis, poliomyelitis, and malaria surveillance, control, and treatment; microcephaly; dengue; and vaccinations. The populations affected by the emergencies experienced reduced health services, which included fewer health visits, failures in the diagnostic chain, decrease in vaccination, and increased incidence or underreporting of notifiable diseases. Conclusions. Socioeconomic inequity is a determinant of the effects of public health emergencies of international concern within affected populations. The diversion of resources and attention from health authorities disproportionately affects vulnerable populations and can lead, over time, to a weakening of health systems. The analysis of the effects of public health emergencies is important for the development of new protocols that can better respond to future crises.

RESUMEN Objetivos. Evaluar el conocimiento acumulado acerca de los efectos de las emergencias de salud pública de importancia internacional en el control de enfermedades y en los sistemas de salud locales, y contribuir a una mejor comprensión de estos efectos en los programas y sistemas de salud. Métodos. Se hizo una revisión sistemática de bibliografía gris y publicada (en español, inglés o portugués) para la que se realizaron búsquedas en bases de datos electrónicas (BVS/LILACS, PubMed y SciELO) y en Google Scholar. Los términos de búsqueda fueron: COVID-19 OR H1N1 OR Ebola OR Zika OR poliomyelitis AND (Outbreaks OR epidemics) AND (public health systems OR public health surveillance). Resultados. Se encontraron 3 508 estudios, de los cuales 31 cumplieron los criterios de inclusión. En los estudios se abordaban los efectos de las emergencias en: los sistemas de notificación de enfermedades transmisibles; la vigilancia, el control y el tratamiento de la malaria, el VIH/sida, la tuberculosis y la poliomielitis; la microcefalia; el dengue; y las vacunas. Las poblaciones afectadas por las emergencias experimentaron una reducción de los servicios de salud, incluida una reducción de las consultas de salud, errores en la cadena de diagnóstico, una disminución de la vacunación y el aumento de la incidencia o subnotificación de enfermedades de notificación obligatoria. Conclusiones. La inequidad socioeconómica es un determinante de los efectos de las emergencias de salud pública de importancia internacional en los grupos poblacionales afectados. El desvío de recursos y atención de las autoridades de salud afecta desproporcionadamente a los grupos vulnerables y puede suponer, con el tiempo, un debilitamiento de los sistemas de salud. El análisis de los efectos de las emergencias de salud pública es crucial para la elaboración de nuevos protocolos que puedan mejorar la respuesta ante futuras crisis.

RESUMO Objetivos. Avaliar o conhecimento acumulado sobre os efeitos das emergências de saúde pública de importância internacional no controle de doenças e nos sistemas de saúde locais e contribuir para uma melhor compreensão desses efeitos sobre os programas e sistemas de saúde. Métodos. Trata-se de uma revisão sistemática da literatura branca e cinzenta (em inglês, português ou espanhol) realizada por meio de pesquisas nos bancos de dados eletrônicos BVS/LILACS, PubMed e SciELO e no Google Scholar. Foram utilizados os seguintes termos de busca: COVID-19 OR H1N1 OR Ebola OR Zika OR poliomyelitis AND (outbreaks OR epidemics) AND (public health systems OR public health surveillance). Resultados. Foi identificado um total de 3 508 estudos, dos quais 31 preencheram os critérios de inclusão. Os estudos abordavam os efeitos das emergências sobre: sistemas de notificação de doenças transmissíveis; vigilância, controle e tratamento de HIV/AIDS, tuberculose, poliomielite e malária; microcefalia; dengue; e vacinações. As populações afetadas pelas emergências enfrentaram uma redução nos serviços de saúde, como menos consultas médicas, problemas na cadeia de diagnóstico, diminuição da vacinação e maior incidência ou subnotificação de doenças de notificação compulsória. Conclusões. A desigualdade socioeconômica é um fator determinante dos efeitos das emergências de saúde pública de importância internacional nas populações afetadas. O desvio dos recursos e da atenção das autoridades sanitárias afeta desproporcionalmente as populações vulneráveis e pode levar, com o passar do tempo, a um enfraquecimento dos sistemas de saúde. A análise dos efeitos das emergências de saúde pública é importante para a elaboração de novos protocolos que possam enfrentar melhor futuras crises.

Effects of face mask on pulse rate and blood oxygenation

ABSTRACT Objective The World Health Organization and Centers for Disease Control and Prevention recommend the use of face masks in public. This study aimed to evaluate the effects of face masks on pulse rate and partial blood oxygen saturation in patients without cardiorespiratory disorders. Methods A total of 150 volunteers of both sexes were divided into three groups (n=50) according to age (children, young adults, and older adults). The partial blood oxygen saturation and pulse rate were measured for each volunteer using a digital oximeter while wearing a facial mask and remaining at rest. The masks were removed for two minutes, and partial blood oxygen saturation and pulse rate were remeasured. The materials and types of masks used were recorded. The t -test for paired samples was used to compare the mean values obtained before and after removing the masks. Results The most frequently used mask was a two-layered cloth (64.7%). A decrease in pulse rate was observed after removing the face mask in males, particularly in children (p=0.006) and young adults (p=0.034). Partial blood oxygen saturation levels increased in young adult males after mask removal (p=0.01). Conclusion The two-layer cotton tissue face masks are associated with a higher pulse rate and reduced arterial blood oxygen saturation without associated clinical disorders, mainly in adult men with a lower tolerance to breathing and ear discomfort.

Resumo Fundamento A estratificação do risco de morte dos pacientes no contexto da angioplastia primária (ATC) é fundamental. Objetivo Identificar os fatores relacionados ao desfecho morte em pacientes submetidos a ATC. Métodos Estudo de caso-controle, utilizando como fonte de dados um registro brasileiro. A associação entre cada variável e o desfecho óbito foi avaliada via modelo de regressão logística binária. Consideramos significativo p<0,05. Resultados Foram analisados 26.990 registros, sendo 18.834 (69,8%) do sexo masculino, com idade mediana de 61 (17) anos. Na análise multivariada, as principais variáveis relacionadas ao desfecho óbito com seus respectivos odds ratio e intervalos de confiança (IC) com nível de significância de 95% foram a idade avançada 70 - 79 anos (2,46; 1,64 - 3,79) e ≥ 80 anos (3,68; 2,38 - 5,81), p<0,001, classificação de Killip II (2,71; 1,92 - 3,83), Killip III (8,14; 5,67 - 11,64), Killip IV (19,83; 14,85 - 26,69), p<0,001, disfunção global acentuada do ventrículo esquerdo (VE) (3,63; 2,39 - 5,68), p<0,001 e ocorrência de infarto após a intervenção (5,01; 2,57- 9,46), p<0,001. O principal fator protetor foi o fluxo TIMI III pós-intervenção (0,18; 0,13 - 0,24), p<0,001, seguido do TIMI II (0,59; 0,41 - 0,86), p=0,005, sexo masculino (0,79; 0,64 - 0,98), p= 0,032, dislipidemia (0,69; 0,59 - 0,85), p<0,001 e número de lesões tratadas (0,86; 0,9 - 0,94), p<0,001. Conclusão Os preditores de mortalidade nos pacientes submetidos a ATC foram: classificação de Killip, reinfarto, idade, disfunção global acentuada do VE, sexo feminino e fluxo TIMI 0/I pós-intervenção.

Abstract Background Identification of high-risk patients undergoing primary angioplasty (PCI) is essential. Objective Identify factors related to the causes of death in PCI patients. Methods This work consisted of a multicenter case-control study using a Brazilian registry of cardiovascular interventions as the data source. The association between each variable and death was assessed using a binary logistic regression model, p <0.05 was considered significant. Results A total of 26,990 records were analyzed, of which 18,834 (69.8%) were male patients, with a median age of 61 (±17) years. In the multivariate analysis, the main variables related to the causes of death with their respective odds ratios and 95%confidence intervals (CI) were advanced age, 70-79 years (2.46; 1.64-3.79) and ≥ 80 years (3.69; 2.38-5.81), p<0.001; the classification of Killip II (2.71; 1.92-3.83), Killip III (8.14; 5.67-11.64), and Killip IV (19.83; 14.85-26.69), p<0.001; accentuated global dysfunction (3.63; 2,39-5.68), p<0.001; and the occurrence of infarction after intervention (5.01; 2.57-9.46), p<0.001. The main protective factor was the post-intervention thrombolysis in myocardial infarction (TIMI) III flow (0.18; 0.13-0.24), p<0.001, followed by TIMI II (0.59; 0.41 -0.86), p=0.005, and male (0.79; 0.64-0.98), p = 0.032; dyslipidemia (0.69; 0.59-0.85), p<0.001; and number of lesions treated (0.86; 0.9-0.94), p<0.001. Conclusion The predictors of mortality in patients undergoing PCI were Killip's classification, reinfarction, advanced age, severe left ventricular dysfunction, female gender, and post-intervention TIMI 0 / I flow.

Vascular Spectrum of Imaging Findings in COVID-19: Ischemic, Hemorrhagic, and Thromboembolic Complications

Abstract Ischemic strokes secondary to occlusion of large vessels have been described in patients with COVID-19. Also, venous thrombosis and pulmonary thromboembolism have been related to the disease. Vascular occlusion may be associated with a prothrombotic state due to COVID-19-related coagulopathy and endotheliopathy. Intracranial hemorrhagic lesions can additionally be seen in these patients. The causative mechanism of hemorrhage could be associated with anticoagulant therapy or factors such as coagulopathy and endotheliopathy. We report on cases of ischemic, thrombotic, and hemorrhagic complications in six patients diagnosed with SARS-CoV-2 infection. Chest computed tomography (CT) showed typical SARS-CoV-2 pneumonia findings in all the cases, which were all confirmed by either serology or reverse transcription polymerase chain reaction (RT-PCR) tests.

Non-surgical management of vesicoureteral junction obstruction: a case report / Manejo não cirúrgico da obstrução da junção vesicoureteral: um relato de caso

Abstract Objective: To report the case of a pediatric patient with bilateral hydronephrosis due to vesicoureteral junction obstruction (VUJO) that was treated non-surgically and to discuss the approach of this anomaly. Case Description: A 25-month-old boy was referred without complaints for consultation due to prenatal ultrasound showing kidneys with cysts. He was under antibiotic prophylaxis. No family history of kidney disease and/or inherited disorders was reported. Renal ultrasound (RUS) at 2 days of life showed bilateral hydronephrosis, thus ruling out the possibility of kidney cystic disease. Dynamic renal scintigraphy (DTPA) showed marked retention of the marker in the pyelocaliceal system bilaterally, with little response to diuretic drug. He was maintained under antibiotic prophylaxis, when a new RUS showed bilateral ureteral dilatation, abrupt stenosis in the ureterovesical transition region (0.2 cm caliber), moderate bilateral hydronephrosis, and slight renal cortical thickness, confirming the diagnosis of VUJO. At 2 years and 10 months of age, DTPA showed hydronephrosis and ureteral stasis in both kidneys secondary to stenosis at the vesicoureteral junction (VUJ) level, with preservation of kidney function and slow degree of emptying. We opted for a non-surgical approach. RUS at 10 years of age showed significant improvement of all parameters, with ureteral transverse diameter of 9 mm, preserved VUJ, and age-appropriate bilateral kidney development. Comments: VUJO is a major cause of prenatal hydronephrosis and can trigger a deterioration of kidney function. Its treatment is still controversial but should take into account the importance of clinical follow-up and serial imaging evaluation.

Resumo Objetivo: Relatar o caso de um paciente pediátrico com hidronefrose bilateral devido à obstrução da junção vesicoureteral (OJVU) que foi tratado não cirurgicamente e discutir a abordagem desta anomalia. Descrição do caso: Um menino de 25 meses de idade foi encaminhado sem queixas para consulta devido à ultrassonografia pré-natal que mostrou rins com cistos. Ele estava sob profilaxia antibiótica. Nenhum histórico familiar de doença renal e/ou distúrbios hereditários foi relatado. A ultrassonografia renal (USR) aos 2 dias de vida mostrou hidronefrose bilateral, descartando assim a possibilidade de doença renal cística. A cintilografia renal dinâmica (DTPA) mostrou uma retenção acentuada do marcador no sistema pielocalicial bilateralmente, com pouca resposta ao diurético. O paciente foi mantido em profilaxia antibiótica, quando uma nova USR apresentou dilatação ureteral bilateral, estenose abrupta na região de transição ureterovesical (calibre 0,2 cm), hidronefrose bilateral moderada e leve espessura cortical renal, confirmando o diagnóstico de OJVU. Aos 2 anos e 10 meses de idade, a DTPA mostrou hidronefrose e estase ureteral em ambos os rins secundárias à estenose no nível da junção vesicoureteral (JVU), com preservação da função renal e grau lento de esvaziamento. Optamos por uma abordagem não cirúrgica. A USR aos 10 anos de idade mostrou melhora significativa de todos os parâmetros, com diâmetro transverso ureteral de 9 mm, JVU preservada, e desenvolvimento renal bilateral adequado à idade. Comentários: A OJVU é uma das principais causas de hidronefrose pré-natal e pode desencadear uma deterioração da função renal. Seu tratamento ainda é controverso, mas deve levar em consideração a importância do acompanhamento clínico e da avaliação seriada por imagem.

Terapia de presión negativa para el manejo de abdomen catastrófico secundario a íleo biliar / Negative Pressure Therapy for Managing Catastrophic Abdomen following Gallstone Ileus

Introducción: El abdomen catastrófico o abdomen hostil es una entidad quirúrgica de gran importancia por la pérdida de los distintos espacios entre los órganos de la cavidad abdominal y las estructuras de la cavidad abdominal. Estas alteraciones producen cambios anatómicos grandes por un síndrome adherencial severo. Objetivo: Demostrar la presentación de un abdomen catastrófico posterior a manejo de íleo biliar en un paciente adulto. Caso clínico: Paciente masculino de 43 años que producto de un abdomen agudo obstructivo por íleo biliar evolucionó tórpidamente en otra casa asistencial. Se realizaron 3 intervenciones quirúrgicas, hasta llegar a nuestra casa asistencial donde se le trata de manera multidisciplinaria e integral. Estuvo 120 días hospitalizado y se le realizó 5 intervenciones quirúrgicas para aplicación y recambio de terapia de presión negativa abdominal abierta (ABThera). Durante la última intervención al encontrar una cavidad limpia y sin fugas se realiza gastroentero anastomosis en Y de Roux con una buena evolución clínico-quirúrgica hasta el alta, con seguimiento dos meses posteriores por consulta externa. Conclusiones: El abdomen catastrófico es un reto para el manejo por los cirujanos porque se requiere aparte de un vasto conocimiento también el apoyo de otras especialidades para poder combatir esta entidad(AU)

Introduction: Catastrophic abdomen or hostile abdomen is a surgical entity of great significance due to the loss of the different spaces between organs and the structures of the abdominal cavity. These alterations produce major anatomical changes due to a severe adhesive syndrome. Objective: To show the presentation of a catastrophic abdomen following gallstone ileus management in an adult patient. Clinical case: A 43-year-old male patient who, as a consequence of an acute obstructive abdomen due to gallstone ileus, had a torpid evolution into another care facility. Three surgical interventions were performed before he arrived at our care facility, where he was treated in a multidisciplinary and comprehensive way. He was hospitalized for 120 days and underwent five surgical interventions for application and replacement of the open abdomen negative pressure therapy (ABThera). During the last intervention, upon finding a clean cavity without leaks, a Roux-en-Y gastroenteric anastomosis was performed, with a good clinical-surgical evolution until discharge and follow-up of two months thereafter in the outpatient clinic. Conclusions: Catastrophic abdomen is a challenge to be managed by surgeons because it requires, apart from vast knowledge, the support of other specialties to combat this entity(AU)

Preoperative risk factors associated with anastomotic leakage after colectomy for colorectal cancer: a systematic review and meta-analysis / Fatores de risco pré-operatórios associados à fístula anastomótica após colectomia para câncer colorretal: revisão sistemática e metanálise

ABSTRACT Introduction: anastomotic leak (AL) after colectomy for colorectal cancer (CRC) is a life-threatening complication. This systematic review and meta-analysis aimed to evaluate the preoperative risk factors for AL in patients submitted to colectomy. Methods: the bibliographic search covered 15 years and 9 months, from 1st January 2005 to 19th October 2020 and was performed using PubMed, Cochrane Library, Scopus, Biblioteca Virtual em Saúde, Europe PMC and Web of Science databases. The inclusion criteria were cross-sectional, cohort and case-control studies on preoperative risk factors for AL (outcome). The Newcastle-Ottawa scale was used for bias assessment within studies. Meta-analysis involved the calculation of treatment effects for each individual study including odds ratio (OR), relative risk (RR) and 95% confidence intervals (95% CI) with construction of a random-effects model to evaluate the impact of each variable on the outcome. Statistical significance was set at p<0.05. Results: cross-sectional studies were represented by 39 articles, cohort studies by 21 articles and case-control by 4 articles. Meta-analysis identified 14 main risk factors for AL in CRC patients after colectomy, namely male sex (RR=1.56; 95% CI=1.40-1.75), smoking (RR=1.48; 95% CI=1.30-1.69), alcohol consumption (RR=1.35; 95% CI=1.21-1.52), diabetes mellitus (RR=1.97; 95% CI=1.44-2.70), lung diseases (RR=2.14; 95% CI=1.21-3.78), chronic obstructive pulmonary disease (RR=1.10; 95% IC=1.04-1.16), coronary artery disease (RR=1.61; 95% CI=1.07-2.41), chronic kidney disease (RR=1.34; 95% CI=1.22-1.47), high ASA grades (RR=1.70; 95% CI=1.37-2.09), previous abdominal surgery (RR=1.30; 95% CI=1.04-1.64), CRC-related emergency surgery (RR=1.61; 95% CI=1.26-2.07), neoadjuvant chemotherapy (RR=2.16; 95% CI=1.17-4.02), radiotherapy (RR=2.36; 95% CI=1.33-4.19) and chemoradiotherapy (RR=1.58; 95% CI=1.06-2.35). Conclusions: important preoperative risk factors for colorectal AL in CRC patients have been identified based on best evidence-based research, and such knowledge should influence decisions regarding treatment.

RESUMO Objetivo: fístula anastomótica (FA) após colectomia para câncer colorretal (CCR) é complicação grave. Esta revisão sistemática e meta-análise avaliou os fatores de risco pré-operatórios para FA em pacientes submetidos à colectomia. Métodos: a pesquisa bibliográfica abrangeu 15 anos e 9 meses (1 de janeiro de 2005 - 19 de outubro de 2020), sendo utilizadas as plataformas PubMed, Cochrane Library, Scopus, Biblioteca Virtual em Saúde, Europe PMC e Web of Science. O critério de inclusão foram estudos transversais, coorte e caso-controle em fatores de risco pré-operatórios para FA (desfecho). A escala Newcastle-Ottawa foi usada para avaliação de viés dos estudos. A metanálise envolveu o cálculo dos efeitos de tratamento para cada estudo individualmente incluindo odds ratio (OR), risco relativo (RR) e intervalo de confiança de 95% (IC95%) com construção de modelo de efeitos aleatórios, para avaliar o impacto de cada variável (p<0,05). Resultados: foram selecionados 39 estudos transversais, 21 coortes e quatro casos-controle.

Conclusões: importantes fatores de risco pré-operatórios para FA colorretais em pacientes com CCR foram identificados com base nas melhores pesquisas baseadas em evidências e esse conhecimento deve influenciar decisões relacionadas ao tratamento.

Prevalence of tungiasis in humans in Brazil and in its federative units: a systematic review

Tungiasis is a neglected parasitic disease caused by penetration of female Tunga penetrans under the skin, causing important health outcomes in humans. Therefore, the aim of this study was to describe the prevalence of tungiasis in Brazil and in its federative units. In November 2019, an investigation was carried out to find studies published from 1980 onwards in MEDLINE, LILACS, Cochrane, CINAHL, Scopus, Web of Science and Embase databases, and in the gray literature, using descriptors related to the prevalence of tungiasis caused by T. penetrans in Brazil. Of the 542 studies found, only 16 published between 2002 and 2010 met the eligibility criteria to be included in this systematic review. Of the 16 selected publications, 14 addressed the prevalence of tungiasis in communities in the Northeast region of the country, one in the South and one in the Southeast. The general prevalence of the parasitosis in the studies ranged from 1.6% to 54.8%, predominantly in the five to nine age group. Eight studies considered the prevalence by gender, ranging from 2.2% to 62.2% for females and 1.1% to 62.5% for males. This systematic review presents an unprecedented survey of the prevalence of tungiasis, a parasitic disease whose dissemination is facilitated by several factors, occuring mainly in low-income communities. Considering the regionalization of the findings, the scarcity of publications, as well as disease neglect, more studies are required.

Burden of syphilis in Brazil and federated units, 1990-2016: estimates from the Global Burden of Disease Study 2019

ABSTRACT Background: Syphilis is a chronic infectious disease that has created challenging situations for humanity for centuries. Transmission can occur sexually or vertically, with great repercussions on populations, particularly among women and children. The present study presents information on the main burden imposed by syphilis generated by the Global Burden of Disease (GBD) Study 2019 for Brazil and its 27 federated units. Methods: We described the metrics of incidence, deaths, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life years (DALYs), standardized by age and per 100,000 inhabitants, from 1990 to 2019, and we compared the disease burden between the years 1990 and 2019. Results: In Brazil, the disease burden increased between 2005 and 2019 for all metrics. Although a higher incidence of syphilis was found among women in 2019, DALYs [YLLs (males: 15.9%; females: 21.8%), YLDs (males: 25.0%; females: 50.0%), and DALYs (males: 16.2%; females: 22.4%)] were higher among men. In 2019, the highest DALY rate per 100,000 inhabitants was observed in individuals aged above 50 years. The State of Maranhão presented the highest values of DALYs {1990: 165.2 [95% uncertainty interval (UI) 96.2-264.4]; 2005: 43.8 [95% UI 30.3-62.4]; 2019: 29.1 [95% UI 19.8-41.1]} per 100,000 inhabitants in the three years analyzed. Conclusions: The burden of syphilis has increased in recent years. Men presented higher DALYs, although the incidence of the disease was higher in women. Syphilis affects a large number of people across all age groups, causing different degrees of disability and premature death (DALYs).

Antenatal Diagnosis of Parapagus Conjoined Twins: 3D Virtual and 3D Physical Models / Diagnóstico antenatal de gêmeos unidos parapagus: Modelos 3D virtuais e físicos

Abstract Conjoined twins (CTs) are a rare complication from monochorionic and monoamniotic twin pregnancies. We describe the use of 3D technologies, including 3D virtual and 3D physical models on prenatal evaluation of one parapagus CT. A 16-year-old G1P0 woman was referred for fetal magnetic resonance imaging (MRI) anatomical evaluation of a CT at 28 weeks of gestation. 3D images of the fetal surface were generated by the software during the examination for spatial comprehension of the relationship between the fetal parts. The pair of CTs died at the 32nd week of gestation, a few hours after cesarean section. 3D technologies are an important tool for parental counseling and preparation of the multidisciplinary care team for delivery and neonatal assistance and possible surgical planning for postnatal separation in CTs cases.

Resumo Gêmeos unidos (GUs) são uma complicação rara de gestações gemelares monocoriônicas e monoamnióticas. Descrevemos o uso de tecnologias 3D, incluindo modelos 3D virtuais e físicos, na avaliação pré-natal de GU parapagus. Mulher de 16 anos, G1P0, foi encaminhada para avaliação anatômica por ressonância magnética (RM) fetal de GU com 28 semanas de gestação. Imagens 3D da superfície fetal foram geradas pelo software durante o exame para compreensão espacial da relação entre as partes fetais. O par de GUs morreu na 32ª semana de gestação, poucas horas após a cesariana. As tecnologias 3D são uma importante ferramenta de aconselhamento dos pais e de preparação da equipe multiprofissional para o parto e a assistência neonatal, além de possível planejamento cirúrgico para separação pós-natal em casos de GUs.

Introducción. El enterocele es causado por un defecto herniario del piso pélvico, siendo el más común la hernia interrecto-vaginal. Se produce por un debilitamiento del piso pélvico, por diversos factores, entre ellos, las cirugías en la región pélvica, el estreñimiento crónico o las patologías que aumentan la presión intraabdominal, el antecedente de prolapso rectal o vaginal, y también, factores congénitos. Presentación de caso. Paciente femenina de 84 años de edad, con antecedentes de un parto eutócico y múltiples procedimientos quirúrgicos, entre ellos histerectomía hace 40 años y rectosigmoidectomía por enfermedad diverticular complicada hace 6 años, quien cuatro meses antes presenta constipación crónica, que empeora en los días previos a su ingreso, con dolor perineal intenso y salida de asas intestinales a nivel de la región perineal, que la obliga a consultar a Urgencias. Al encontrarse con asas intestinales expuestas, con cambios de coloración, es intervenida quirúrgicamente con resultado satisfactorio, postquirúrgico inmediato optimo y seguimiento por consulta externa por 3 meses sin evidencia de recidiva. Discusión. La hernia interrecto-vaginal tiene una incidencia baja y una presentación clínica variada. El único tratamiento es quirúrgico

Introduction. The enterocele is produced by an hernia defect of the pelvic floor, being the most common the interrecto-vaginal hernia. It is produced by weakness of the pelvic floor for multiples factors, among them surgeries of the pelvic region, chronic constipation or pathologies that increase intra-abdominal pressure, a history of rectal or vaginal prolapse, and congenital factors. Case report. A 84-year-old female patient, with a history of eutocic delivery and multiple surgical procedures, including hysterectomy 40 years ago and rectosigmoidectomy for complicated diverticular disease 6 years ago, presented four months earlier with chronic constipation, which worsens in the days before her admission, with intense perineal pain and exit of intestinal loops at the level of the perineal region, which forced her to consult the emergency room. At examination the intestinal loops were found exposed, with color changes, she underwent surgery with satisfactory results, optimal immediate postoperative and outpatient follow-up for 3 months with no evidence of recurrence. Discussion. Interrecto-vaginal hernia has a low incidence and a varied clinical presentation. The only treatment is surgery

Methodology: was developed and implemented over a month, a questionnaire to identify risk factors of 101 patients of both sexes. Results: of the total of these patients, 49% were below 45 years, 33% between 45 and 65 and 18% over 65 years. The white prevailed in 66% and 36% of the total had hypertension, diabetes 10% and 7% other chronic diseases. In relation to body mass index (BMI), 4% were below 20Kg/ m2, 37% normal, 30% overweight, 24% with obesity grade I and 5% with BMI greater than 35kg/m2. It was found that 76% of the population was sedentary, 35% smokers, 32% with alcohol consumption less than 3 times a week, 3% more than 3 times and 65% with no consumption of alcohol. As the intake of milk, not the 37% and 40% consumed only 1 day. There was no statistical difference between people who knew or not osteoporosis, while 60% had knowledge about the disease, but this level of education did not lead to differences in living habits. Discussion: in 100% of the studied sample was found at least 1 risk factor for its development, especially the low calcium intake and lack of physical activity, confirming the importance of intervention in those preventable factors.

Excessive prenatal supplementation of iodine and fetal goiter: report of two cases using three-dimensional ultrasound and magnetic resonance imaging / Suplementação pré-natal excessiva de iodo e bócio fetal: Relato de dois casos utilizando ultrassonografia tridimensional e ressonância magnética

Abstract Fetal thyroid complications in pregnancy are uncommon, and are commonly related to the passage of substances through the placenta. The excessive iodine intake during the pregnancy is a well-known mechanism of fetal thyroid enlargement or goiter, and invasive procedures have been proposed for the treatment of fetal thyroid pathologies. In the present report, we demonstrate two cases from different centers of prenatal diagnosis of fetal thyroid enlargement and/or goiter in three fetuses (one pair of twins, wherein both fetuses were affected, and one singleton pregnancy). The anamnesis revealed the ingestion of iodine by the patients, prescribed from inadequate vitamin supplementation. In both cases, the cessation of iodine supplement intake resulted in a marked reduction of the volume of the fetal thyroid glands, demonstrating that conservative treatmentmay be an option in those cases. Also, clinicians must be aware that patients may be exposed to harmful dosages or substances during pregnancy.

Resumo As complicações fetais da tireoide na gravidez são incomuns e são comumente relacionadas à passagem de substâncias pela placenta. A ingestão excessiva de iodo durante a gravidez é um mecanismo bem conhecido de aumento da tireoide ou bócio fetal, e procedimentos invasivos foram propostos para o tratamento de patologias da tireoide fetal. No presente relato de caso, demonstramos dois casos de diferentes centros de diagnóstico pré-natal de aumento da tireoide fetal e/ou bócio em três fetos (um par de gêmeos, em que ambos os fetos foram afetados, e uma gravidez única). A anamnese revelou a ingestão de iodo pelos pacientes prescrita por suplementação inadequada de vitaminas. Nos dois casos, a interrupção da ingestão de suplemento de iodo resultou em uma redução acentuada do volume das glândulas tireoides fetais, demonstrando que o tratamento conservador pode ser uma opção nestes casos. Além disso, os médicos devem estar cientes de que as pacientes podem ser expostas a doses ou substâncias nocivas durante a gravidez.

The spawning method affects the reproductive efficiency of piracanjuba fish (Brycon orbignyanus) in restocking programs / El método de desove afecta la eficiencia reproductiva de piracanjuba (Brycon orbignyanus) en programas de repoblación / O método de desova afeta a eficiência reprodutiva de piracanjuba (Brycon orbignyanus) em programas de repovoamento

Abstract Background: Preserving the genetic diversity of wild fish is an important consideration for restocking programs, as inbreeding can compromise progeny survival as well as impact the resilience of natural populations. Objective: To evaluate the influence of spawning method: semi-natural (SN) or strip-spawning (ST), and the number of breeders (1♀:3♂ and 2♀:6♂) on the reproductive efficiency and genetic diversity of B. orbignyanus progeny destined for restoration of wild stocks. Methods: Rates of fertilization, hatching and broodfish mortality were recorded. For genetic evaluations (allele frequency, observed and expected heterozygosity, Shannon index, inbreeding coefficient, molecular variance analysis, and genetic differentiation), breeders (n=24), and their progenies (90 larvae/treatment) were sampled and analyzed using eight microsatellite markers. Results: Higher fertilization and hatching rates, and lower broodfish mortality were observed for the SN method (p<0.05), whereas the number of breeders did not affect these parameters (p>0.05). Interaction between spawning method and number of breeders was not significant (p>0.05). The amplified microsatellite loci produced a total of 30 alleles, with sizes between 80 and 225 bp and their frequencies indicated an increase (p<0.05) of genetic diversity in the progenies, but low genetic differentiation between treatments (p>0.05). Conclusion: The spawning methods and number of breeders tested increased equally the genetic diversity of the progeny, with low genetic differentiation between treatments. In contrast, rates of fertilization, hatching and brood fish mortality revealed that the SN method resulted in the best reproductive efficiency due to the handling stress and injuries caused by ST. Thus, SN proves to be the most suitable spawning-method for B. orbignyanus in restocking programs.

Resumen Antecedentes: Mantener la diversidad genética de los peces salvajes es una consideración importante para los programas de repoblación, ya que la endogamia puede comprometer la supervivencia de la progenie y afectar la supervivencia de las poblaciones naturales. Objetivo: Evaluar la influencia del método de desove (seminatural - SN o en franjas - ST) y el número de reproductores (1♀:3♂ y 2♀:6♂) sobre la eficiencia reproductiva y la diversidad genética de progenies de B. orbignyanus destinados a la restauración de poblaciones silvestres. Métodos: Se monitorearon las tasas de fertilización, eclosión y mortalidad de reproductores. Para las evaluaciones genéticas (frecuencias alélicas, heterocigosidad observada y esperada, índice de Shannon, coeficiente de endogamia, análisis de varianza molecular y diferenciación genética) los reproductores (n=24) y su progenie (90 larvas/tratamiento) se muestrearon y analizaron utilizando ocho marcadores microsatélites. Resultados: La interacción entre el método de desove y el número de reproductores no fue significativa (p>0,05). Se obtuvieron mejores tasas de fecundación y eclosión (p<0,05), y una menor mortalidad de reproductores (p<0,05) con el método SN, mientras que el número de reproductores no tuvo efecto (p>0,05). Los loci de microsatélites amplificados produjeron un total de 30 alelos con tamaños entre 80 y 225 pb, y sus frecuencias indicaron un aumento (p<0,05) en la diversidad genética de las progenies, pero una baja diferenciación genética entre tratamientos (p>0,05). Conclusión: Los métodos de desove y el número de reproductores evaluados aumentaron de la misma manera la diversidad genética de las progenies, con baja diferenciación genética entre tratamientos. En contraste, las tasas de fecundación, eclosión y mortalidad de peces reproductores revelaron que el SN tuvo la mejor eficiencia reproductiva, un hecho relacionado con el estrés del manejo y las lesiones causadas por el ST. Por lo tanto, el SN demuestra ser el método de desove más adecuado para B. orbignyanus en los programas de repoblación.

Resumo Antecedentes: A manutenção da diversidade genética dos peixes selvagens é uma importante consideração para programas de repovoamento, já que a endogamia pode comprometer a sobrevivência da progênie, além de impactar na resiliência das populações naturais. Objetivo: Avaliar a influência do método de desova (semi-natural - SN ou por extrusão - ST) e número de reprodutores (1♀:3♂ e 2♀:6♂) na eficiência reprodutiva e na diversidade genética de progênie de B. orbignyanus destinados à recuperação de estoques selvagens. Métodos: Taxas de fertilização, eclosão e mortalidade de reprodutores foram monitorados. Para avaliações genéticas (frequências alélicas, heterozigosidade observada e esperada, índice de Shannon, coeficiente de endogamia, análise de variância molecular e diferenciação genética), reprodutores (n=24) e sua progênie (90 larvas/tratamento) foram amostrados e analisados utilizando oito marcadores microssatélites. Resultados: Interação entre método de desova e número de reprodutores não foi significante (p>0,05). Melhores taxas de fertilização e eclosão (p<0,05), e menor (p<0,05) mortalidade de reprodutores foram observados para o método SN, enquanto que o número de reprodutores não afetou esses parâmetros (p>0,05). Os loci microssatélites amplificados produziram um total de 30 alelos, com tamanhos entre 80 e 225 pb e suas frequências indicaram aumento (p<0,05) da diversidade genética nas progênies, mas baixa diferenciação genética entre os tratamentos (p>0,05). Conclusão: Os métodos de desova e números de reprodutores avaliados aumentaram igualmente a diversidade genética das progênies, com baixa diferenciação genética entre tratamentos. Em contraste, as taxas de fecundação, eclosão e mortalidade de reprodutores revelaram que SN obteve a melhor eficiência reprodutiva, fato relacionado com o estresse de manipulação e injurias causadas por ST. Por isso, SN se mostrou como o método de desova mais adequado para B. orbignyanus em programas de repovoamento.
