Approximately two-thirds of patients with colorectal cancer (CRC) undergo resection curative intent; however, 30% to 50% these experience recurrence. The concentration cell-free DNA (cfDNA) before and after surgery may be related the prognosis CRC, but there is limited information regarding cfDNA levels at time surgery. Here, we analyzed surgical release using plasma samples from 30 three key points during surgery: preoperative (immediately surgery), intraoperative (during postoperative (at...
Abstract Colorectal cancer is the third leading cause of cancer-related mortality in Brazil. Proper staging crucial for management patients with rectal cancer, as implemented therapies may result implications prognosis and quality life. The therapeutic armamentarium has evolved over time, highlighting importance magnetic resonance imaging (MRI) preoperative evaluation. This study aims to assess correlation between clinical by MRI pathological individuals cancer. Cross-sectional observational...
Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) is characterized by the congenital absence of uterus and vagina in females with 46, XX karyotype. The genetic etiology remains poorly understood. We described a 29-year-old female patient main complaint primary amenorrhea. MRKHS diagnosis was confirmed, molecular analysis revealed 7q11.23 microduplication proband that shown to be inherited from her mother. In literature, müllerian malformations have been reported only few cases...
Queimaduras são comuns globalmente, afetando aproximadamente um milhão de pessoas no Brasil anualmente. Este estudo realizado em centro referência Curitiba/PR investigou a autoestima e satisfação sexual dos pacientes do ambulatório queimados. Pesquisa transversal, observacional analítica por meio Burn Sexuality Questionnaire 50 adultos (18-75 anos), todos sexualmente ativos. Dos participantes, 56% eram mulheres 44% homens, com idade média 34,5 anos. Quanto ao estado civil, 42% casados 54%...
Background The COVID-19 pandemic has led to high levels of physical, psychological, and social stress among health care professionals, including postgraduate students in medical multidisciplinary residencies. This is associated with the intense fear occupational exposure SARS-CoV-2, virus known cause COVID-19. These professionals are at risk developing physical mental illnesses not only due infection but also prolonged multidimensional continued work overload. Objective study aims evaluate...
Background Since the beginning of COVID-19 pandemic, health professionals have been working under extreme conditions, increasing risk physical and mental illness. We evaluated prevalence burnout its associated factors among postgraduate student residents in professions during global crisis. Methods Healthcare were recruited from all across Brazil between July September 2020 through digital forms containing instruments for assessing (Oldenburg Burnout Inventory (OLBI)), resilience (brief...

Abstract Background The COVID-19 pandemic put healthcare professionals, including residents (postgraduate trainees of health professions), under intense physical and psychological stress, hence at risk for mental disorders. We evaluated the prevalence disorders among during pandemic. Methods From July to September 2020, in medicine other specialties Brazil were recruited. participants completed electronic forms with validated questionnaires (DASS-21, PHQ-9, BRCS) screen depression, anxiety,...
Liver and biliary tract diseases are common causes of morbidity mortality worldwide. Invasive procedures usually performed in those patients with hepatobiliary for both diagnostic therapeutic purposes. Defining proper indications restraints commonly used techniques is crucial patient selection, maximizing positive results limiting complications. In 2018, the Brazilian Society Hepato-logy (SBH) cooperation Interventional Radiology Endovascular surgery (SOBRICE) Digestive Endoscopy (SOBED)...
We establish the existence of a solution to nonlinear competitive Schr\"odinger system whose scalar potential tends positive constant at infinity with an appropriate rate. This has property that all components are invariant under action group linear isometries and each component is obtained from previous one by composing it some fixed isometry. call pinwheel solution. describe asymptotic behavior least energy solutions when competing parameter zero minus infinity. In latter case segregated...
Resumo O vírus da dengue, membro família Flaviviridae, causa uma arbovirose prevalente em regiões tropicais e subtropicais, transmitida por mosquitos Aedes. Estima-se entre 100–400 milhões de novas infecções anualmente, com subnotificação devidas a sistemas vigilância limitados. A infecção pode variar assintomática síndrome do choque dengue. Em 2024, o Brasil enfrenta situação endêmica observando um aumento sazonal significativo notificação mais 4,5 casos prováveis. Exames imagem como...
We present a new approach to solve Schrödinger Equation autonomous at infinity, by identifying the relation between arrangement of spectrum concerned operator and behavior nonlinearity zero infinity. In order apply variational methods, we set up suitable linking structure depending on growth nonlinear term making use information about problem Our method allows us circumvent lack compactness. The main novelty is that none monotonicity assumption required nonlinearity, which may be...
Introdução O câncer colorretal é a terceira causa de mortalidade relacionada neoplasias malignas no Brasil. estadiamento adequado fundamental seu tratamento, pois as condutas médicas podem ter implicações relacionadas ao prognóstico e à qualidade vida do paciente. clínico tão importante para avaliar decisões tratamento quanto o patológico, que pode ser principal fator associado. A ressonância magnética alta resolução utilizada na avaliação pré-operatória invasão locorregional retal, estudo...
Introdução O câncer colorretal é o terceiro mais frequente em casos novos diagnosticados, e a segunda causa mundial de mortalidade, com cerca 940 mil mortes 2020. reto representa 40% dos colorretal, afeta aproximadamente 43 pessoas nos Estados Unidos anualmente, sendo que 48% pacientes são diagnosticados estádios II III. tratamento envolve neoadjuvância, cirúrgico quimioterapia adjuvante.
