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. Introdução , (DRET) COVID19.

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.

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. resourcelimited resource limited countries Gerais Brazil PRISMA.

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. public disorders 15 n=50 n50 n 50 (n=50 children, (children adults. . adults) rest minutes remeasured recorded test twolayered layered 64.7%. 647 64.7% 64 7 (64.7%) p=0.006 p0006 p 0 006 (p=0.006 p=0.034. p0034 p=0.034 034 (p=0.034) p=0.01. p001 p=0.01 01 (p=0.01) twolayer layer discomfort 1 n=5 n5 5 (n=5 64.7 6 (64.7% p=0.00 p000 00 (p=0.00 p003 p=0.03 03 (p=0.034 p00 p=0.0 (p=0.01 n= (n= 64.

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.

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: 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. A metanálise identificou 14 fatores de risco para FA em pacientes com CCR após colectomia, que são sexo masculino (RR=1,56; IC 95%=1,40-1,75), tabagismo (RR=1,48; IC 95%=1,30-1,69), alcoolismo (RR=1,35; IC 95%=1,21-1,52), diabetes mellitus (RR=1,97; IC 95%=1,44-2,70), doenças pulmonares (RR=2,14; IC 95%=1,21-3,78), doença pulmonar obstrutiva crônica (RR=1,10; IC 95%=1,04-1,16), doença coronariana (RR=1,61; IC 95%=1,07-2,41), doença renal crônica (RR=1,34; IC 95%=1,22-1,47), altas notas na escala ASA (RR=1,70; IC 95%=1,37-2,09), cirurgia abdominal prévia (RR=1,30; IC 95%=1,04-1,64), cirurgia de emergência (RR=1,61; IC 95%=1,26-2,07), quimioterapia neoadjuvante (RR=2,16; IC 95%=1,17-4,02), radioterapia (RR=2,36; IC 95%=1,33-4,19) e quimiorradioterapia (RR=1,58; IC 95%=1,06-2,35). 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.

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.

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).

RESUMO OBJETIVO O consumo excessivo de álcool é um problema de saúde presente no mundo inteiro. Este artigo avalia o consumo de bebidas alcoólicas por estudantes de Medicina e sua relação com características pessoais e aspectos sociais. MÉTODOS Estudo realizado com estudantes dos 1o, 3o e 6o anos do curso de medicina da Universidade Federal de Minas Gerais no ano de 2019. Os alunos foram convidados a participar anonimamente, respondendo a um questionário com 15 perguntas relativas a características do estudante (sexo, idade, renda familiar, prática de atividades físicas, origem, condição de moradia e desempenho discente) e ao consumo de bebidas alcoólicas (início, motivo, ocasiões de uso, tipo de bebida, quantidade consumida). Os dados foram comparados com significância correspondente a p<0,05. RESULTADOS Um total de 382 estudantes de ambos os sexos respondeu ao questionário. O consumo de bebidas alcoólicas foi relatado por 85% dos entrevistados. Cerca de 70% dos alunos de 1o e 3o anos e 47% dos alunos do 6o ano foram motivados pela socialização com colegas. O consumo de bebida alcoólica foi prevalente entre os que praticavam atividades físicas (93%) e moravam com a família (89%). Ao redor de 80% consumiram bebidas alcoólicas antes do ingresso na faculdade, com maior frequência no sexo masculino. CONCLUSÕES O consumo de álcool começa durante o ensino médio, estimulado pela socialização. Os homens que praticam atividades físicas e moram com a família são os maiores consumidores.

SUMMARY OBJECTIVE Excessive alcohol consumption is a global health issue. This article aims to evaluate the consumption of alcohol by medical students in relation to their personal and social aspects. METHODS This study was conducted with students in the first, third, and sixth year of medical school at the Federal University of Minas Gerais in 2019. Students were invited to participate anonymously by responding to a questionnaire with 15 questions regarding student characteristics (gender, age, family income, physical activity, origin, housing condition, and academic performance) and alcohol consumption (onset, reason, occasions of use, type of drink, amount consumed). Data were compared with significance corresponding to p<0.05. RESULTS A sample of 382 students of both sexes responded to the questionnaire. Alcohol consumption was reported by 85% of students. About 70% of first and third-year students and 47% of those of the sixth year were motivated by socializing with peers. Alcohol consumption was prevalent among those who practice physical activities (93%) and live with their families (89%). Around 80% had consumed alcohol before starting medical school, and consumption was more frequent in males. CONCLUSIONS Alcohol consumption begins during high school, stimulated by socialization. Men who practice physical activities and live with their families are the largest consumers.
