Low back pain, pelvic pain, and associated factors in type 1 diabetic pregnant women

Abstract Introduction Pregnancy and diabetes mellitus promote several musculoskeletal changes predisposing this population to complaints of Lower Back (LB) and Pelvic Pain (PP). Objective To assess the frequency of LB and PP and associated factors in type 1 Diabetic (DM1) pregnant women. Method: An observational analytical cross-sectional study. Thirty-six pregnant women with DM1 were evaluated through a postural assessment with a focus on pelvic positioning and what patients reported. The associated factors were assessed using the State-Trait Anxiety Inventory (STAI), the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF), and the Female Sexual Function Index (FSFI). Results The frequency of LB and PP was 55.6 % and 30.6 %, respectively. The presence of anxiety was not associated with a higher prevalence of pain. The incidence of sexual dysfunctions was higher in the GD. DM1 duration had a mean of 14.9 years (± 8.2 SD) in the GD and 9.0 years (± 6.9 SD) in the GSD, which was statistically significant (p ≤ 0.050). In the multiple binary regression analysis for the occurrence of pain, the independent factor was DM1 duration ≥ 17 years (OR = 11.2; 95 % CI = 1.02‒124.75). The association between DM1 duration ≥ 17 years and being overweight showed a probability of 95 % for the studied population in the analysis of the probabilities of occurrence of the pain event. Conclusion There was a high frequency of LB and PP related to pregnancy in DM1 pregnant women in the second trimester of pregnancy. The incidence of sexual dysfunction and DM1 duration ≥ 17 years increases the chance that DM1 pregnant women will experience pain. There was no association between anxiety. urinary incontinence and pain in DM1 pregnant women.

Modelos pré-clínicos de câncer hepático / Preclinical models of liver câncer

ABSTRACT Background: This manuscript provides an overview of liver carcinogenesis in murine models of hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA). Objective: A review through MEDLINE and EMBASE was performed to assess articles until August 2022. Methods: Search was conducted of the entire electronic databases and the keywords used was HCC, CCA, carcinogenesis, animal models and liver. Articles exclusion was based on the lack of close relation to the subject. Carcinogenesis models of HCC include HCC induced by senescence in transgenic animals, HCC diet-induced, HCC induced by chemotoxicagents, xenograft, oncogenes, and HCC in transgenic animals inoculated with B and C virus. The models of CCA include the use of dimethylnitrosamine (DMN), diethylnitrosamine (DEN), thioacetamide (TAA), and carbon tetrachloride (CCl4). CCA murine models may also be induced by: CCA cells, genetic manipulation, Smad4, PTEN and p53 knockout, xenograft, and DEN-left median bile duct ligation. Results: In this review, we described different murine models of carcinogenesis that reproduce the key points for HCC and CCA genesis allowing a better understanding of its genetic, physiopathological, and environmental abnormalities. Conclusion: Each model has its advantages, disadvantages, similarities, and differences with the corresponding human disease and should be chosen according to the specificity of the study. Ultimately, those models can also be used for testing new anticancer therapeutic approaches.

Polimorfismo no gene PNPLA3 e o consumo de carne vermelha aumentam o risco de fibrose em pacientes com DHGNA comprovado por biópsia em acompanhamento médico em um centro terciário no Sudoeste do Brasil / Pnpla3 gene polymorphism and red meat consumption increased fibrosis risk in nash biopsy-proven patients under medical follow-up in a tertiary center in southwest brazil

ABSTRACT Background: Recent studies show an increase in nonalcoholic fatty liver disease (NAFLD) in populations with higher consumption of red meat, processed and cooked at high temperatures. On the other hand, the single nucleotide polymorphism rs738409 in the Patatin-like phospholipase domain containing 3 (PNPLA3) gene has been implicated in susceptibility to NAFLD and liver fibrosis. However, the synergistic effect between red meat consumption and the PNPLA3 gene polymorphism in NAFLD has not yet been evaluated. Objective: To evaluate the association between the presence of the polymorphism in the PNPLA3 gene and the consumption of macronutrients, including meat consumption and its cooking method among NAFLD patients. Methods: This was a cross-sectional study with 91 patients diagnosed with NAFLD by liver biopsy with genotyping for the polymorphism in the PNPLA3 gene were included. The consumption of calories and macronutrients was verified using the semi-quantitative food frequency questionnaire and the specific questionnaire on meat consumption. PNPLA3 gene polymorphism was analyzed by real-time polymerase chain reaction (RT-PCR) and anthropometric evaluation was realized. Results: The mean BMI was 32.38±4.58 kg/m² and the waist circumference was 107±10 cm. On liver biopsy, 42% of patients had significant fibrosis (F≥2). The odds ratio of F≥2 was 2.12 for the GG group and 1.54 for the CG group, compared to the CC group. The mean caloric intake was 1170±463.20 kcal/d. The odds ratio in the CC group concerning high red meat consumption in comparison to low consumption was 1.33. For white meat, the odds ratio was 0.8 when comparing high and low intake, also in the CC group. Conclusion: High red meat intake and PNPLA3 gene polymorphism seem to synergistically affect NAFLD and liver fibrosis, requiring confirmation in a larger number of patients and in different populations.

RESUMO Contexto: Estudos recentes mostram um aumento da doença hepática gordurosa não alcoólica (DHGNA) em populações com maior consumo de carne vermelha, processada e cozida em altas temperaturas. Por outro lado, o polimorfismo rs738409 no gene Patatin-like fosfolipase contendo 3 (PNPLA3) tem sido implicado na suscetibilidade à DHGNA e fibrose hepática. No entanto, o efeito sinérgico entre o consumo de carne vermelha e o polimorfismo no gene PNPLA3 na DHGNA ainda não foi avaliado. Objetivo: Avaliar a associação entre a presença do polimorfismo no gene PNPLA3 e o consumo de macronutrientes, incluindo o consumo de carne e seu modo de cozimento em pacientes com DHGNA. Métodos: Realizamos um estudo transversal com 91 pacientes diagnosticados com DHGNA por biópsia hepática e genotipados para o polimorfismo no gene PNPLA3. O consumo de calorias e macronutrientes foi verificado por meio do questionário de frequência alimentar semi-quantitativo (QFA) e do questionário específico sobre consumo de carnes. O polimorfismo no gene PNPLA3 foi analisado por reação em cadeia da polimerase em tempo real (RT-PCR) e a avaliação antropométrica foi realizada. Resultados: O índice de massa corporal médio foi de 32,38±4,58 kg/m² e a circunferência da cintura foi de 107±10 cm. Na biópsia hepática, 42% dos pacientes apresentavam fibrose significativa (F≥2). O odds ratio de F≥2 foi de 2,12 para o grupo GG e 1,54 para o grupo GC, comparado ao grupo CC. A ingestão calórica média foi de 1.170±463,20 kcal/d. O odds ratio para alto consumo de carne vermelha no grupo CC em comparação ao baixo consumo foi de 1,33. Para a carne branca, este valor foi de 0,8 ao comparar o alto e o baixo consumo, também no grupo CC. Conclusão: A alta ingestão de carne vermelha e o polimorfismo no gene PNPLA3 parecem afetar sinergicamente a DHGNA e a fibrose hepática, necessitando de confirmação em maior número de pacientes e em diferentes populações.

Saúde bucal e condições sistêmicas em idosos da Baixada Fluminense: coorte retrospectivo / Oral health and systemic conditions in elderly people from Baixada Fluminense: retrospective cohort

O equilíbrio sistêmico e a saúde bucal são condições clínicas que estabelecem entre si uma relação multidimensional capaz de exercer grande impacto sobre o bem-estar cotidiano do indivíduo. As disfunções metabólicas associadas ao estado nutricional e a perda da capacidade muscular geram uma maior necessidade de cuidados em pessoas idosas. Sob o ponto de vista odontológico a presença de dentes naturais bem como o grau de doença periodontal, estão associados a competência mastigatória e, desta forma, são fatores determinantes na saúde da população acima dos 60 anos de idade. O presente estudo teve como objetivo avaliar, através da análise retrospectiva dos últimos 05 anos, a relação entre a saúde bucal e as condições sistêmicas de indivíduos acima de 60 anos residentes na Baixada Fluminense (Rio de Janeiro/Brasil) com evidente crescimento demográfico populacional. Para isso foram analisados 11.390 prontuários de pacientes usuários da Clínica Odontológica da Universidade Iguaçu/RJ sendo selecionados 1.125 que atendiam aos critérios de inclusão. Os resultados destacam a presença de doença periodontal em cerca de 56% dos indivíduos diabéticos, além de 43% com quadro hipertensivo no momento do atendimento apontando para uma importante relação entre a atenção com a saúde bucal da população assistida nessa região e suas condições sistêmicas.

Systemic balance and oral health are clinical conditions that establish a multidimensional relationship capable of having a great impact on the individual's daily well-being. Metabolic dysfunctions associated with nutritional status and loss of muscle capacity generate a greater need for care in the elderly. From the dental point of view, the presence of natural teeth, as well as the degree of periodontal disease, are associated with masticatory competence and, thus, are determining factors in the health of the population over 60 years of age. The present study aimed to describe descriptively, through the retrospective analysis of the last 05 years, the relationship between oral health and the systemic conditions of individuals over 60 years old living in the Baixada Fluminense (Rio de Janeiro / Brazil) with evident population demographic growth. For that purpose, 11,390 medical records of patients who were users of the Clínica Odontológica of Universidade Iguaçu / RJ were analyzed, 1,125 who met the inclusion criteria were selected. The results highlight the presence of periodontal disease in about 56% of diabetic individuals, in addition to 43% with the hypertensive condition at the time of care, pointing to an important relationship between the attention to the oral health of the assisted population in this region and their systemic conditions.

Atividade física, comportamento sedentário e absenteísmo de professores da educação básica / Physical activity, sedentary behaviour and basic education teacher absenteeism / Actividad física, sedentarismo y ausentismo de profesores de enseñanza básica

O absenteísmo é caracterizado pelo distanciamento do funcionário ao trabalho, se tratando de um fenômeno complexo e multifatorial. Devido ao número de afastamentos atribuídos em 2018, o objetivo deste estudo foi verificar a associação entre nível de atividade física (NAF), comportamento sedentário (CS) e absenteísmo de professores da educação básica do município de Divinópolis-MG. A amostra foi composta por 84 docentes de ambos os sexos, com idade média de 45,12±8,88 anos. Realizou-se a identificação do absenteísmo através de questionário sociodemográfico e para NAF e CS utilizou-se o International Physical Activity Questionnarie (IPAQ) - versão curta. O valor de alfa foi estabelecido em 5%. A análise de relação, dada pelo Qui- Quadrado, demonstrou que o não absenteísmo no ano de 2019 está relacionado com exercer cargo efetivo (p=0,030), lecionar no Ensino Fundamental I (p=0,041) e ser fisicamente ativo (p=0,003). Pode-se observar pela correlação de Spearman que o absenteísmo está correlacionado ao NAF (rho=-0,321; p=0,003) e ao cargo exercido (rho= 0,237; p=0,030). A Regressão de Poisson indicou que docentes com cargo temporário apresentaram 74% menos chances de ocorrência de absenteísmo quando comparados àqueles que exerciam cargo efetivo (p<0,001; Exp. ß= 0,744; IC=0,655- 0,844) e que professores irregularmente ativos demonstraram 123% mais chances de ocorrência de afastamento comparados aos fisicamente ativos (p=0,004; Exp. ß= 1,234; IC=1,070-1,423). Conclui-se que docentes fisicamente ativos, que atuavam em cargos temporários no Ensino Fundamental I, comparados com professores do Ensino Infantil, possuíam menor probabilidade de absenteísmo, sugerindo que o NAF pode ser preditor do afastamento de professores da rede municipal.

Absenteeism is characterized by the distancing of the employee from work, being a complex and multifactorial phenomenon. Due to the number of absences attributed in 2018, the objective of this study was to verify the association between physical activity level (PAL), sedentary behavior (CS) and absenteeism of basic education teachers in the city of Divinópolis-MG. The sample consisted of 84 teachers of both genders, with a mean age of 45.12±8.88 years old. The identification of absenteeism was carried out through a sociodemographic questionnaire and for PAL and CS the International Physical Activity Questionnarie (IPAQ) - short version was used. The alpha value was set at 5%. The relationship analysis, given by the Chi-Square, showed that non- absenteeism in 2019 is related to holding an effective position (p=0.030), teaching in Elementary School I (p=0.041) and being physically active (p=0.003). It can be seen from Spearman's correlation that absenteeism is correlated with PAL (rho=-0.321; p=0.003) and position held (rho= 0.237; p=0.030). Poisson Regression indicated that professors with a temporary position were 74% less likely to have absenteeism when compared to those who held a permanent position (p<0.001; Exp. ß= 0.744; CI=0.655-0.844) and that irregularly active professors demonstrated 123% more chances of sick leave compared to physically active (p=0.004; Exp. ß= 1.234; CI=1.070-1.423). It is concluded that physically active teachers, who worked in temporary positions in Elementary School I, compared to teachers in Kindergarten, had a lower probability of absenteeism, suggesting that the PAL can be a predictor of the removal of teachers from the municipal network.

El ausentismo se caracteriza por el alejamiento del empleado del trabajo, siendo un fenómeno complejo y multifactorial. Debido al número de ausencias atribuidas en 2018, el objetivo de este estudio fue verificar la asociación entre el nivel de actividad física (NAC), el comportamiento sedentario (CS) y el ausentismo de los profesores de educación básica en la ciudad de Divinópolis-MG. La muestra fue constituida por 84 profesores de ambos sexos, con edad media de 45,12±8,88 años. La identificación del absentismo se realizó a través de un cuestionario sociodemográfico y para PAL y CS se utilizó el International Physical Activity Questionnarie (IPAQ) - versión corta. El valor alfa se fijó en el 5%. El análisis de relación, dado por el Chi-Cuadrado, mostró que el no ausentismo en 2019 está relacionado con ocupar un cargo efectivo (p=0,030), enseñar en la Escuela Primaria I (p=0,041) y ser físicamente activo (p=0,003). De la correlación de Spearman se desprende que el absentismo está correlacionado con el PAL (rho=-0,321; p=0,003) y el cargo desempeñado (rho= 0,237; p=0,030). La regresión de Poisson indicó que los profesores con un puesto temporal tenían un 74% menos de probabilidades de absentismo en comparación con los que ocupaban un puesto permanente (p<0,001; Exp. ß= 0,744; CI=0,655-0,844) y que los profesores irregularmente activos mostraban un 123% más de probabilidades de baja por enfermedad en comparación con los físicamente activos (p=0,004; Exp. ß= 1,234; CI=1,070-1,423). Se concluye que los profesores físicamente activos, que trabajaban en puestos temporales en la Escuela Primaria I, en comparación con los profesores del Jardín de Infancia, tenían una menor probabilidad de absentismo, lo que sugiere que el PAL puede ser un predictor de la baja de los profesores de la red municipal.

Chagas disease and perceived quality of life: a cross-sectional study

ABSTRACT Background: Chagas disease (ChD) is a neglected tropical disease that is caused by the protozoan parasite Trypanosoma cruzi and can negatively impact quality of life (QoL). This study aimed to assess and compare QoL between individuals with and without ChD. Methods: This cross-sectional study was performed within a concurrent cohort study (REDS). The participants were derived from two blood donation centers: São Paulo capital and Montes Claros, Minas Gerais, Brazil. Participants with ChD were identified in blood donations by serological diagnosis between 2008 and 2010, and those without ChD were donors with negative serology identified during the same period. QoL was assessed using the World Health Organization Quality of Life-BREF questionnaire. Logistic regression was used to compare sociodemographic and clinical characteristics between the groups, and mean, standard deviation, and beta regression were used to compare QoL. Results: In total, 611 individuals participated in the study (328 with ChD and 283 without ChD). Participants with ChD had lower QoL in the physical (p=0.02) and psychological (p<0.01) domains than did individuals without CD. Conclusions: Individuals with ChD had worse QoL perceptions. These results provide a comprehensive understanding of the impact of ChD on individuals' QoL, while also highlighting potential opportunities for improving the care and treatment of those affected.

Brazilian evidence-based guideline for screening, diagnosis, treatment, and follow-up of metabolic dysfunction-associated steatotic liver disease (MASLD) in adult individuals with overweight or obesity: A joint position statement from the Brazilian Society of Endocrinology and Metabolism (SBEM), Brazilian Society of Hepatology (SBH), and Brazilian Association for the Study of Obesity and Metabolic Syndrome (Abeso)

ABSTRACT Introduction: Metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as Nonalcoholic fatty liver disease (NAFLD), is one of the most common hepatic diseases in individuals with overweight or obesity. In this context, a panel of experts from three medical societies was organized to develop an evidence-based guideline on the screening, diagnosis, treatment, and follow-up of MASLD. Material and methods: A MEDLINE search was performed to identify randomized clinical trials, meta-analyses, cohort studies, observational studies, and other relevant studies on NAFLD. In the absence of studies on a certain topic or when the quality of the study was not adequate, the opinion of experts was adopted. Classes of Recommendation and Levels of Evidence were determined using prespecified criteria. Results: Based on the literature review, 48 specific recommendations were elaborated, including 11 on screening and diagnosis, 9 on follow-up, 14 on nonpharmacologic treatment, and 14 on pharmacologic and surgical treatment. Conclusions: A literature search allowed the development of evidence-based guidelines on the screening, diagnosis, treatment, and follow-up of MASLD in individuals with overweight or obesity.

Higher immunoexpression of CK14 from the Wnt-1/β-catenin pathway in the development of odontomas

Abstract Tooth development depends on a series of reciprocal signaling interactions between the oral epithelium and ectomesenchyme. This study aimed to investigate the role of CK14, a protein involved in Wnt-1/β-catenin signaling, in odontogenesis and the development of odontomas. This cross-sectional, retrospective, immunohistochemical study analyzed 30 compound odontomas, 30 complex odontomas, and 17 tooth germs. Higher immunoexpression of CK14 was observed in odontogenic epithelial cells of tooth germs (p < 0.001) and odontogenic epithelial cells of odontomas (p < 0.001). There was higher immunoexpression of Wnt-1 and β-catenin proteins in epithelial cells of tooth germs (p = 0.002 and p < 0.001, respectively), as well as in the ectomesenchyme of odontomas (p = 0.003 and p < 0.001, respectively). β-Catenin was moderately and significantly correlated with CK14 in the membrane of reduced enamel epithelial cells in odontomas (p = 0.007). Higher immunoexpression of CK14 was observed in the odontogenic epithelium during the bud and cap stages and lower immunoexpression in the internal enamel epithelium during the bell stage. In odontomas, lower expression of Wnt-1/β-catenin and higher immunoexpression of CK14 were found in odontogenic epithelial cells, especially adjacent to the mineralized material resembling the tooth formed in these lesions.

Resumo O desenvolvimento dentário depende de uma série de interações de sinalização recíproca entre o epitélio oral e o ectomesênquima. O objetivo deste estudo foi investigar o papel da CK14 das vias WNT-1/β-catenina na odontogênese e no desenvolvimento de odontomas. Este estudo transversal, retrospectivo, imuno-histoquímico analisou 30 odontomas compostos, 30 odontomas complexos e 17 germes dentários. A CK14 apresentou maior imunoexpressão em células epiteliais odontogênicas de germes dentários (p<0,001) e em células epiteliais odontogênicas de odontomas (p<0,001). A Wnt-1 e a β-catenina apresentaram maior imunoexpressão de proteínas nas células epiteliais dos germes dentários (p = 0,002 e p<0,001, respectivamente), bem como no ectomesênquima dos odontomas (p = 0,003 e p < 0,001, respectivamente). A β-catenina correlacionou-se moderada e significativamente com a CK14 na membrana de células epiteliais reduzidas do esmalte em odontomas (p = 0,007). Maior imunoexpressão da CK14 foi observada no epitélio odontogênico nos estágios de botão e capuz com menor imunoexpressão no epitélio interno do órgão do esmalte no estágio de sino. Nos odontomas, foi observado menor expressão de Wnt-1/β-catenina e maior imunoexpressão da CK14 presente nas células epiteliais odontogênicas, especialmente, vizinhas ao material mineralizado semelhante ao dente formado nessas lesões.

Evaluation of the properties of WHODAS-12 measurements in individuals with Chagas disease in Brazil

ABSTRACT Numerous tests employed to predict cardiac and functional status are expensive and not widely accessible for a considerable number of patients, particularly those diagnosed with Chagas disease (CD) residing in remote and endemic regions. To date, there is no knowledge of studies that have validated instruments that address functionality in an expanded way, including the biopsychosocial factors in patients with CD. This study aims to evaluate the psychometric properties of the World Health Organization Disability Assessment Schedule (WHODAS 2.0), in its 12-item shortened version (WHODAS-12) when applied to patients with CD. This is a cross-sectional study of a prospective cohort that follows individuals with CD (SaMi-Trop). Data collection took place between October 2019 and March 2020. In the interviews, sociodemographic information, life habits, clinical information, and indicators of disability measured by WHODAS-12 were collected. Descriptive analysis, internal consistency and construct validity of the instrument were performed. A total of 628 patients with CD were interviewed, most were women (69.5%), their mean age was of 57 years, and most declared an average self-perception of health (43.4%). The 12 items of WHODAS-12 were distributed into three factors, which together account for 61% of the variance. The Kaiser-Meyer-Olkin (KMO) index was 0.90, indicating adequacy of the sample for factor analysis. The internal consistency of the global scale showed alpha = 0.87. The percentage of incapacity was 16.05%, indicating mild incapacity for the evaluated patients. WHODAS-12 is a valid and reliable measure to assess the disability of the Brazilian population with CD.

Incontinência urinária e disfunção sexual em gestantes diabéticas tipo 1: resultados preliminares / Urinary incontinence and sexual dysfunction in type 1 diabetic pregnant women: preliminary results

Introdução: A gestação e o diabetes mellitus promovem diversas alterações musculoesqueléticas, predispondo disfunções miccionais e sexuais. Objetivo: Avaliar a frequência de incontinência urinária e disfunção sexual em gestantes diabéticas tipo 1. Métodos: Estudo analítico, observacional do tipo transversal. Foram avaliadas 13 gestantes com diabetes do tipo 1 no período de abril 2017 a fevereiro 2018, por meio dos Questionários International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) e o Female Sexual Function Index (FSFI). Foi utilizado o programa estatístico SPSS versão 20.1 para análise de dados, avaliando a média e desvio padrão (DP), tendência central e dispersão, frequência absoluta (n) e relativa (%). Para correlação entre o ICIQ e o FSFI o teste de correlação linear de Pearson. Resultados: Frequência de incontinência urinária foi 38,5%, o que demonstrou impacto leve na qualidade de vida das gestantes. O escore geral do FSFI foi de 20,49, identificando a presença de disfunção sexual (FSFI ≤ 26). No grupo de gestantes, 92,3% (n = 12) apresentaram disfunção sexual, os domínios satisfação e excitação com maiores prevalências. Correlacionando o ICIQ-SF com FSFI, houve correlação moderada, mas não significativa (r = 0,534; p = 0,60). As amostras apresentaram distribuição normal de acordo com o teste de Levene. Conclusão: A frequência de incontinência urinária em gestantes diabéticas do tipo 1 foi baixa, mas houve presença de disfunção sexual, os domínios satisfação e excitação foram os mais frequentes.

O projeto enfatizou a importância de enfrentarmos o racismo para que os princípios de universalidade, igualdade e equidade possam garantir o direito à saúde e proteger a vida da população negra.

Oral manifestations of leukemia as part of early diagnosis

ABSTRACT Introduction: The oral cavity can present the first clinical manifestations of leukemia, therefore; it is important to recognize their principal characteristics. Objective: To identify oral manifestations as the first clinical signs of leukemia. Methods: This is an integrative review, that gathered data from articles with oral manifestations of leukemia as part of its first clinical features. The were included case reports, case series, clinical research, or reviews with case reports. The variables that were considered relevant: age, sex, sites of the oral lesions, characteristics of the oral lesions, medical history and physical examination, time of evolution, radiographic examination, blood test results, initial diagnosis, differential diagnosis and final diagnosis. Results: A total of 31 studies were included, with a total of 33 individuals identified. There were 19 (57.57%) males and 14 (42.42%) females. The age range was from 1.6 to 74 years. Acute myeloid leukemia (72.72%) and acute lymphoid leukemia (18.18%) presented more oral manifestations as the first clinical signs of the disease. All individuals with leukemia presented lesions, such as ulcer, erosion, bleeding, ecchymosis, color change of the bluish or pale mucous membranes and areas of tissue necrosis. Hard tissue lesions were less frequent, being 6 (18.18%). Conclusion: The first clinical manifestations of leukemia can be present in the oral cavity, mainly in acute myeloid leukemia. The principal oral tissues affected were gingival tissue, buccal mucosa and hard and/or soft palate. When hard tissues, such as the maxilla bone or mandible bone were affected, dental mobility was the principal clinical sign.

Double Product and Autonomic Function as Predictors of Quality of Life in Heart Transplant Recipients: A Cross-Sectional Study

ABSTRACT Introduction: Heart rate control by the autonomic nervous system (ANS) is impaired in heart transplant (HT) recipients, leading to increased resting heart rate, metabolic demand, and fatigue, which can impair their quality of life (QoL). In this study, we hypothesized the association of hemodynamics and autonomic function as predictors of QoL in HT recipients. Methods: This is a cross-sectional study conducted with HT recipients aged ≥ 18 years at ambulatorial accompaniment. Blood pressure was used for hemodynamics assessment, and heart rate variability (HRV) was used for ANS assessment. QoL was assessed by the 36-item Short Form Health Survey. The significance level was set as P≤0.05. Results: Twenty-two volunteers were included in the study. Systolic blood pressure (SBP) and double product (DP) were significantly negatively associated with the physical functioning domain of QoL. DP, the number of consecutive normal RR interval differences > 50 ms (NN50), and the percentage of normal RR intervals that differed by > 50 ms from the adjacent interval (PNN50) exhibited negative association with the physical role domain. NN50 and PNN50 were significantly associated with bodily pain, social functioning, and emotional role domains. SBP was negatively associated with the vitality domain. Considering general and mental health domains, no variable demonstrated significant association. DP, NN50, and PNN50 were negatively associated with the total score of QoL. Conclusion: This study demonstrated DP and HRV as predictors of QoL in HT recipients. These innovative results can become a relevant therapeutic target for improving QoL in HT recipients prior to its deterioration.

O papel do enfermeiro na prevenção do delirium no paciente adulto/idoso crítico / The nurse's role in preventing delirium in critically ill adult/elderly patients

Introdução: Delirium é uma disfunção cerebral aguda, associado ao aumento da mortalidade e morbilidade, que atinge frequentemente o paciente adulto/idoso crítico. O enfermeiro tem um papel determinante na prevenção/controlo do delirium, através da implementação de intervenções não farmacológicas. Objetivo: Conhecer as intervenções de enfermagem na identificação, prevenção e controlo do delirium no paciente adulto/idoso crítico. Materiais e métodos: Realizada uma Revisão Integrativa da Literatura de artigos publicados entre 2014 e 2018, que identificaram intervenções de enfermagem dirigidas à prevenção e controlo do delirium no paciente adulto/idoso crítico. Foram realizadas quatro pesquisas, nas bases de dados electrónicas da EBSCOhost e na B-on. Resultados: Identificaram-se 13 estudos, que apresentam intervenções de enfermagem, maioritariamente não farmacológicas, para prevenção e controlo do delirium no paciente adulto/idoso crítico. Destas, evidenciam-se intervenções relacionadas com o ambiente, promoção do sono, intervenção terapêutica precoce, avaliação cognitiva e orientação dos pacientes, intervenções sistematizadas em protocolos, bem como intervenções direcionadas à participação dos familiares, à formação dos enfermeiros e ao ensino dos pacientes. Foram também identificados fatores de risco para o desenvolvimento do delirium e instrumentos de avaliação. Discussão: A prevenção do delirium é importante e imperativa, já que nos pacientes críticos a sua ocorrência está associada ao aumento da mortalidade, morbilidade, do tempo de internamento e a um elevado custo hospitalar. A identificação dos fatores de risco para a ocorrência do delirium devem estar incluídos nos protocolos de abordagem do delirium. Conclusão: As evidências demonstraram que o enfermeiro é fundamental na identificação precoce, prevenção e controlo do delirium, evitando a progressão da doença, contribuindo para a diminuição da morbilidade e mortalidade. A intervenção de enfermagem deve incluir a identificação de fatores predisponentes e/ou precipitantes de modo a contribuir para a diminuição da ocorrência e/ou resolução do quadro de delirium.

Introduction: Delirium is an acute brain dysfunction, associated with increased mortality and morbidity, which often affects critically ill adult/elderly patients. Nurses have a crucial role in the prevention/control of delirium, through the implementation of non-pharmacological interventions. Objective: To know the nursing interventions in the identification, prevention and control of delirium in adult/critical elderly patients. Materials and Methods: An Integrative Literature Review of articles published between 2014 and 2018 was carried out, which identified nursing interventions aimed at the prevention and control of delirium in adult/critical elderly patients. Four searches were carried out, in the electronic databases of EBSCOhost and B-on. Results: 13 studies were identified, which present nursing interventions, mostly non-pharmacological, for the prevention and control of delirium in adult/critical elderly patients. Of these, interventions related to the environment, sleep promotion, early therapeutic intervention, cognitive assessment and patient orientation, interventions systematized in protocols, as well as interventions aimed at the participation of family members, the training of nurses and the teaching of patients are evident. Risk factors for the development of delirium and assessment tools were also identified. Discussion: The prevention of delirium is important and imperative, since its occurrence in critically ill patients is associated with increased mortality, morbidity, length of stay and a high hospital cost. The identification of risk factors for the occurrence of delirium should be included in delirium management protocols. Conclusions: Evidence has shown that nurses are essential in the early identification, prevention and control of delirium, preventing the progression of the disease, contributing to the reduction of morbidity and mortality. The nursing intervention must include the identification of predisposing and/or precipitating factors to contribute to the reduction of the occurrence and/or resolution of delirium.

New multienzymatic complex formed between human cathepsin D and snake venom phospholipase A2

Background Cathepsin D (CatD) is a lysosomal proteolytic enzyme expressed in almost all tissues and organs. This protease is a multifunctional enzyme responsible for essential biological processes such as cell cycle regulation, differentiation, migration, tissue remodeling, neuronal growth, ovulation, and apoptosis. The overexpression and hypersecretion of CatD have been correlated with cancer aggressiveness and tumor progression, stimulating cancer cell proliferation, fibroblast growth, and angiogenesis. In addition, some studies report its participation in neurodegenerative diseases and inflammatory processes. In this regard, the search for new inhibitors from natural products could be an alternative against the harmful effects of this enzyme. Methods An investigation was carried out to analyze CatD interaction with snake venom toxins in an attempt to find inhibitory molecules. Interestingly, human CatD shows the ability to bind strongly to snake venom phospholipases A2 (svPLA2), forming a stable muti-enzymatic complex that maintains the catalytic activity of both CatD and PLA2. In addition, this complex remains active even under exposure to the specific inhibitor pepstatin A. Furthermore, the complex formation between CatD and svPLA2 was evidenced by surface plasmon resonance (SPR), two-dimensional electrophoresis, enzymatic assays, and extensive molecular docking and dynamics techniques. Conclusion The present study suggests the versatility of human CatD and svPLA2, showing that these enzymes can form a fully functional new enzymatic complex.

Progression of chronic kidney disease in non- dialysis patients: a retrospective cohort

Abstract Evidence on factors associated with the progression of chronic kidney disease (CKD) is still under construction. The present study aimed to evaluate sociodemographic, clinical, and drug use factors associated with the progression of CKD. A retrospective cohort study was conducted with 193 patients with CKD stages 3A to 5- non-dialysis followed for three years in a Brazilian city. The outcome was the evolution to renal replacement therapy (RRT) or death. A total of 52.3 % (n = 101) were men and 83.4 % (n = 161) elderly. The median age was 72.0 years, and 22.3 % (n = 44) progressed to RRT or death, and the three-year mortality rate was 20.2 %. Participants exposed to angiotensin converting enzyme inhibitors or angiotensin II receptor blockers had a lower risk of progressing to the outcome (hazard ratio (HR) 0.25; p = 0.003) and higher survival (p = 0.022) when compared to those not exposed to these drugs. Age (HR 1.06;) and use of omeprazole (HR 6.25; CI; p <0.01) and hydrochlorothiazide (HR 2.80; p = 0.028) increased the risks of RRT or death. The results highlight the importance of rational management of pharmacotherapy for patients with CKD

Hepatocellular carcinoma (HCC) in patients with Non-Alcoholic Fatty Liver Disease (NAFLD): screening, treatment and survival analysis in a Brazilian series

Abstract Objective: The aim of the present study was to evaluate the clinical features, Hepatocellular Carcinoma (HCC) screening, treatment modalities, and Overall Survival (OS) in a series of Non-Alcoholic Fatty Liver Disease-Related Hepatocellular Carcinoma (NAFLD-HCC) Brazilian patients. Methods: This was a cross-sectional study at the Instituto do Cancer do Estado de São Paulo, at the Faculdade de Medicina da Universidade de São Paulo with the approval of the local research ethics committee. NAFLD patients with HCC diagnosed, from May 2010 to May 2019, were included. Results: A total of 131 patients were included. Risk factors for NAFLD were present in 94.7% of the patients. Only 29% of patients were in the HCC screening program before diagnosis. HCC treatment was performed in 84.7% of patients. Cumulative survival at the end of the first year was 72%, second-year 52%, and fifth-year 32%. HCC screening before diagnosis was not significantly associated with higher cumulative survival. The independent factors associated with shorter general survival were BCLC C-D, p < 0.001, and the size of the largest nodule > 42 mm, p = 0.039. Conclusions: Although the efficacy of screening in our population regarding overall survival was hampered due to the sample size (29% had screening), BCLC stages C‒D and the size of the largest nodule larger than 42 mm were identified as independent factors of worse prognosis.

Contextual influence on poor self-rated health in patients with Chagas disease: multilevel study / Influência contextual na pior autopercepção em saúde de portadores de Doença de Chagas: estudo multinível

Abstract Chagas disease (CD) is recognized by the World Health Organization as one of the thirteen most neglected tropical diseases in the world. Self-perceived health is considered a better predictor of mortality than objective measures of health status, and the context in which one lives influences this predictor. This study aimed to evaluate the prevalence and individual and contextual factors associated with poor self-rated health among CD patients from an endemic region in Brazil. It is a multilevel cross-sectional study. The individual data come from a cross-section of a cohort study named SaMi-Trop. Contextual data was collected from publicly accessible institutional information systems and platforms. The dependent variable was self-perceived health. The analysis was performed using multilevel binary logistic regression. The study included 1,513 patients with CD, where 335 (22.1%) had Poor self-rated health. This study revealed the influence of the organization/offer of the Brazilian public health service and of individual characteristics on the self-perceived health of patients with CD.

Resumo A Doença de Chagas (DC) é reconhecida pela Organização Mundial da Saúde como uma das treze doenças tropicais mais negligenciadas do mundo. A autopercepção de saúde é considerada um melhor preditor de mortalidade do que medidas objetivas do estado de saúde, e o contexto em que se vive influencia esse preditor. O objetivo deste estudo foi avaliar a prevalência e os fatores individuais e contextuais associados à pior autopercepção em saúde de pacientes com DC de uma região endêmica do Brasil. É um estudo transversal multinível. Os dados individuais vêm de um corte transversal de um estudo de coorte denominado SaMi-Trop. Os dados contextuais foram coletados a partir de plataformas e sistemas de informações institucionais acessíveis ao público. A variável dependente foi a autopercepção de saúde. A análise foi realizada por meio de regressão logística binária multinível. Participaram do estudo 1.513 pacientes com DC, sendo 335 (22,1%) com pior autopercepção de saúde. Este estudo revelou a influência da organização/oferta do serviço público de saúde brasileiro e de características individuais na autopercepção de saúde de pacientes com DC.
