Performance of triggers in detecting hospitalizations related to drug-induced respiratory disorders in older adults: A pilot cross-sectional study.

BACKGROUND: There is no gold-standard trigger for detecting drug-induced respiratory disorders, a type of Adverse Drug Event (ADE) with high morbimortality, particularly in older people. OBJECTIVE: To propose and evaluate the performance of triggers for detecting hospitalizations related to drug-induced respiratory disorders in older people. METHODS: A pilot cross-sectional study was conducted with older people (age ≥ 60) admitted to a Brazilian hospital. Electronic chart documentation was screened using ICD-10 codes; Global Trigger Tool (GTT); and drugs potentially associated with respiratory disorders. A chart and medication review were conducted to perform the causality assessment using the instrument developed by the World Health Organization. The performance of triggers was evaluated by the Positive Predictive Value (PPV), with values ≥ 0.20 indicating good performance. RESULTS: Among 221 older people, 72 were eligible. Potential drug-induced dyspnea and/or cough were detected in six older people (6/72), corresponding to a prevalence of 8.3 %. The overall PPV of the triggers was 0.14, with abrupt medication stop (PPV = 1.00), codeine (PPV = 1.00), captopril (PPV = 0.33), and carvedilol (PPV = 0.33) showing good performance. Two triggers were proposed for detecting therapeutic ineffectiveness associated with respiratory disorders: furosemide (PPV = 0.23) and prednisone (PPV = 0.20). CONCLUSION: The triggers enabled the identification that one in 12 hospitalizations was related to drug-induced respiratory. Although good performance was observed in the application of triggers, additional investigations are needed to assess the feasibility of incorporating them into clinical practice for the screening, detection, management, and reporting of these ADEs, which are considered to be underreported and difficult to detect.

Enhanced vegetable production in hydroponic systems using decontamination of closed circulating fluid.

While plant microorganisms can promote plants by producing natural antibiotics, they can also be vectors for disease transmission. Contamination from plant management practices and the surrounding environment can adversely affect plants, leading to infections and hindered growth due to microbial competition for nutrients. The recirculation of nutrient-rich fluids can facilitate the transport of microorganisms between vegetables in the hydroponic production system. This issue can be addressed through the application of the decontamination method in the hydroponic liquid. Ultraviolet light (UV-C) has been employed for microbiology, and its effects on lettuce were evaluated in this study. This study aims to assess the effectiveness of a decontamination system using UV-C in hydroponic solutions during nutrient recirculation in hydroponics. We evaluated the time required for lettuce plants to reach their maximum height, as well as their pigment content, phenolic compounds, antioxidant capacity, and micro and macronutrient levels. The evaluation was conducted under two photoperiods (18 and 20 hours) in lettuce samples exposed to UV-C in the hydroponic fluid, with control groups not exposed to UV-C. The application of the UV-C decontamination system in hydroponic circulation water containing nutrients accelerated plant growth while maintaining nutritional values equal to or higher than those in the control groups without such a system. The results of microorganism control highlight the potential application of this technique for enhancing and expediting vegetable production. This approach reduces production time and enhances nutrient absorption and the content of certain compounds and minerals.

Bons encontros e cidadania: os sentidos atribuídos ao serviço de convivência e fortalecimento de vínculos pelos(as) idosos(as) / Good meetings and citizenship: the meanings attributed to the service of coexistence and strengthening of bonds (serviço de convivência e fortalecimento de vínculos) by older adults / Buenos encuentros y ciudadanía: los significados atribuidos al servicio de convivencia y fortalecimiento de lazos por los adultos mayores

Este artigo tem como objetivo analisar os dados produzidos por uma pesquisa qualitativa que investigou os sentidos atribuídos ao Serviço de Convivência e Fortalecimento de Vínculos (SCFV) por seus usuários(as) em Florianópolis/SC. Por meio da observação participante realizada em um SCFV durante três meses e da aplicação de uma entrevista coletiva com idosos(as), este artigo traz algumas análises sobre os processos de significação vivenciados por esses sujeitos. Apoiados na perspectiva sócio-histórica, elaboramos dois eixos de significação, que serão discutidos neste artigo: 1) Intersubjetividade e vínculo: o SCFV como "lugar acolhedor" e de "bons encontros"; 2) O(a) idoso(a) e os processos de exclusão: o SCFV como promotor da cidadania. Em termos de resultados, é possível afirmar que esse espaço se configura como um lugar importante na vida desses(as) idosos(as) - onde eles(as) se sentem acolhidos, ouvidos e reconhecidos como sujeitos. Além do fato de esse espaço ser marcado por afetos e "bons encontros", o grupo também o revelou como um lugar potente para processos de reflexão e questionamento contra as diversas formas de segregação e violências vividas cotidianamente por ele.(AU)

This study aims to analyze the data produced by qualitative research that investigated the meanings attributed to the Service of Coexistence and Strengthening of Bonds (Serviço de Convivência e Fortalecimento de Vínculos - SCFV) by its users in the municipality of Florianópolis. By participant observation carried out in an SCFV for three months and the application of a collective interview with older adults, this study will bring some analysis of the processes of meaning experienced by these subjects. Sustained by the socio-historical perspective, we elaborated two axes of meaning to be discussed in this study : 1. Intersubjectivity and bonding: the SCFV as a "warm place" and "good meetings;" and 2. Older adults and processes of exclusion: the SCFV as a enhancer of citizenship. Results show that this space configures an important place in the lives of these older adults — a place in which they feel welcomed, heard, and recognized as subjects. In addition to the fact this space is marked by affections and "good meetings," the group also shows itself as a potent place for processes of reflection and questioning against the various forms of segregation and violence daily experienced by these people.(AU)

Este artículo tiene como objetivo analizar los datos producidos por un estudio cualitativo sobre los significados atribuidos al Servicio de Convivencia y Fortalecimiento de Lazos (SCFL) por sus usuarios en Florianópolis (Santa Catarina, Brasil). Desde la observación participante realizada en un SCFL durante el período de tres meses y desde la aplicación de una entrevista colectiva con personas mayores, este artículo presenta algunos análisis sobre los procesos de significado vividos por estos sujetos. Apoyados en la perspectiva sociohistórica, elaboramos dos ejes de significado que serán discutidos: 1) Intersubjetividad y vinculación: el SCFL como "lugar de acogida" y "buenos encuentros"; 2) Las personas mayores y los procesos de exclusión: el SCFV como promotor de ciudadanía. Los resultados permiten afirmar que este espacio se configura como un lugar importante en la vida de estas personas mayores, un lugar donde se sienten acogidos, escuchados y reconocidos como sujetos. Además de que este espacio está marcado por afectos y "buenos encuentros", el grupo también se reveló como un lugar propenso a procesos de reflexión y cuestionamiento frente a las diversas formas de segregación y violencia que viven a diario estas personas.(AU)

Smartphone-based evaluation of static balance and mobility in long-lasting COVID-19 patients.

Background: SARS-CoV-2 infection can lead to a variety of persistent sequelae, collectively known as long COVID-19. Deficits in postural balance have been reported in patients several months after COVID-19 infection. The purpose of this study was to evaluate the static balance and balance of individuals with long COVID-19 using inertial sensors in smartphones. Methods: A total of 73 participants were included in this study, of which 41 had long COVID-19 and 32 served as controls. All participants in the long COVID-19 group reported physical complaints for at least 7 months after SARS-CoV-2 infection. Participants were evaluated using a built-in inertial sensor of a smartphone attached to the low back, which recorded inertial signals during a static balance and mobility task (timed up and go test). The parameters of static balance and mobility obtained from both groups were compared. Results: The groups were matched for age and BMI. Of the 41 participants in the long COVID-19 group, 22 reported balance impairment and 33 had impaired balance in the Sharpened Romberg test. Static balance assessment revealed that the long COVID-19 group had greater postural instability with both eyes open and closed than the control group. In the TUG test, the long COVID-19 group showed greater acceleration during the sit-to-stand transition compared to the control group. Conclusion: The smartphone was feasible to identify losses in the balance motor control and mobility of patients with long-lasting symptomatic COVID-19 even after several months or years. Attention to the balance impairment experienced by these patients could help prevent falls and improve their quality of life, and the use of the smartphone can expand this monitoring for a broader population.

Prevalence, risk indicators, and clinical characteristics of peri-implant mucositis and peri-implantitis for an internal conical connection implant system: A multicenter cross-sectional study.

BACKGROUND: Peri-implant disease prevalence is associated with a multifactorial etiology and distinct clinical characteristics of inflammation. METHODS: The present study aimed to assess the prevalence of peri-implant diseases, identify related risk indicators, and associate specific clinical characteristics to peri-implant biological complications in the medium term. Peri-implant diseases were classified according to established case criteria. Patients' data, implant and/or prosthetic features, and maintenance records were collected. Clinical characteristics such as bleeding on probing (BOP), suppuration (SUPP), keratinized mucosa (KM), probing depth (PD), marginal recession (MR), and modified plaque index (mPI) were recorded. RESULTS: Ninety-nine patients with 266 implants with a mean functional duration of 30.26 months were evaluated. Peri-implant mucositis and peri-implantitis prevalence totaled to 49.5% and 15.15% (patient level), respectively. Peri-implant mucositis was associated with osteoporosis (odds ratio [OR] 6.09), age (OR 0.97), diabetes mellitus (OR 3.09), cemented-retained prosthesis (OR 3.81), and partial prosthesis (OR 2.21). Peri-implantitis was associated with osteoporosis (OR 7.74) and periodontitis (OR 2.74), cemented prosthesis (OR 10.12), partial and full arch prostheses (OR 12.35 and 19.86), implant diameter (OR 3.64), abutment transmucosal height (OR 3.39), and hygiene difficulty (OR 3.14). Furthermore, mPI score 3 (OR 3.27) and PD scores (OR 1.64) were associated with peri-implant mucositis, while mPI score 3 (OR 16.42), KM (OR 1.53), PD (OR 1.81), MR (OR 2.61), and the relationship between KM and PD (OR 0.63) were associated with peri-implantitis. CONCLUSION: In the medium term, peri-implant diseases were correlated with factors inherent to the patient's conditions, presurgical treatment plan, and hygiene maintenance care. The knowledge of the mentioned factors and featured clinical characteristics can be crucial for disease prevention and establishment of a superior implant therapy prognosis.

O artigo apresenta a discussão sobre os quilombos no estado do Rio Grande do Sul (RS) e as aproximações com as ofertas inscritas no Sistema Único de Assistência Social (SUAS), com objetivo de analisar as particularidades da questão étnico-racial acerca dos povos quilombolas no estado do Rio Grande do Sul, para a afirmação desta pauta na agenda do SUAS. Socializa os resultados de uma pesquisa documental de abordagem mista com ênfase qualitativa. Revela a potência e a complementaridade das informações encontradas nos instrumentos do SUAS, como nos dados do Censo SUAS (2019) do Centro de Referência de Assistência Social (CRAS) e do Centro de Referência Especializado de Assistência Social (CREAS) e os dados do Cadastro Único (2021), frente ao reconhecimento dos territórios quilombolas, embora ainda seja necessário ampliar as ações de educação permanente acerca do debate sobre a questão étnico-racial e os quilombos na agenda da política de assistência social

The article presents the discussion about the quilombos in the state of Rio Grande do Sul (RS) and the approximations with the offers registered in the Unified Social Assistance System (SUAS), with the objective of analyzing the particularities of the ethnic-racial issue concerning the quilombola peoples in the state of Rio Grande do Sul, for the affirmation of this agenda in the SUAS agenda. It socializes the results of a mixed approach documentary research with a qualitative emphasis. It reveals the power and complementarity of the information found in the SUAS instruments, as in the data from the SUAS Census (2019) from the Social Assistance Reference Center (CRAS) and the Specialized Reference Center for Social Assistance (CREAS) and data from the Single Registry (2021), in view of the recognition of quilombola territories, although it is still necessary to expand permanent education actions regarding the debate on the ethnic-racial issue and the quilombos in the social assistance policy agenda

Jovens em vulnerabilidades psicossociais: grupo como lugar de acolhimento e subjetivação política / Jóvenes en vulnerabilidades psicosociales: grupo como un sitio de recepción e subjetivación política / Young people in psychosocial vulnerabilities: the group as a device for psychological support and political subjectivation

RESUMO. Este artigo visa relatar uma experiência de estágio realizado em um Serviço de Convivência e Fortalecimento de Vínculos (SCFV) junto a jovens de periferias da cidade de Florianópolis (SC), de modo a problematizar as possibilidades e desafios do uso do dispositivo grupal como instrumento de intervenção psicossocial. Este serviço, vinculado à Proteção Social Básica da Política Nacional de Assistência Social (PNAS), tem como objetivo prevenir as situações de riscos e vulnerabilidades, bem como fortalecer os laços familiares e comunitários. Por meio da intervenção grupal, buscamos, junto com estes(as) jovens, criar um espaço de elaboração psíquica e política sobre temas significativos para suas vidas e para a atual sociedade. Apostamos na ideia de que as oficinas propiciaram a construção de um espaço coletivo que servisse de acolhimento ao sofrimento ético-político destes(as) jovens, subsidiando um afago às dores da vida e, também, servindo de catalisador aos processos de subjetivação política frente às iniquidades sociais que atravessam, sistematicamente, o cotidiano destes(as) jovens. Neste trabalho, trazemos reflexões em torno das potencialidades que o dispositivo grupal pode desencadear na constituição do sujeito, compreendendo-o como uma profícua ferramenta de intervenção psicossocial de escuta, acolhimento, fortalecimento comunitário e protagonismo político.

ABSTRACT. This article aimed to report an experience developed at a Service of Coexistence and Strengthening of Bonds (SCSB) with young people from outskirts of the city of Florianópolis (SC) problematizing the possibilities and challenges of the use of the group as a psychosocial intervention device. This service, linked to the Basic Social Protection of the National Social Assistance Policy, aims to prevent situations of risks and vulnerabilities, as well as strengthen family and community bonds. Through group intervention, we sought, along with these young people, to create a space of psychic and political elaboration on themes that are significant for their lives and for the current society. We believe that the workshops allowed the construction of a collective space that served as support for the ethical-political suffering of these young people, and also served as a catalyst for the processes of political subjectification fighting the social inequities that permeate the daily lives of these young people. In this work, we brought reflections about the potential that the group device can trigger in the constitution of the subject, understanding it as a useful tool for psychosocial intervention of listening, support, community strengthening and political protagonism.

Fatores contribuintes para eventos gastrointestinais e obstrução de sonda enteral identificados e analisados a partir de registros eletrônicos de saúde de pacientes hospitalizados / Contributing factors for gastrointestinal events and enteral probe obstruction identified and analyzed from electronic health records of hospitalized patients

Objetivo: Identificar e analisar os fatores contribuintes para os eventos gastrointestinais e de obstrução de sonda em pacientes hospitalizados em uso de medicamentos por sonda enteral. Método: Estudo observacional transversal realizado através de consulta aos prontuários eletrônicos de pacientes hospitalizados (clínicos e críticos) admitidos no ano de 2018 e que fizeram uso de medicamentos por sonda enteral em um hospital público geral de médio porte e média complexidade do interior de São Paulo (Brasil), em busca dos eventos adversos e de seus fatores contribuintes. Resultados: em 2018 houve 1.735 hospitalizações, das quais 386 (22,2%) contemplaram os critérios de inclusão. Os pacientes, em sua maioria, eram homens (54,4%), idosos (72,8%), de grau fundamental incompleto (48,4%), de baixo peso (35,5%), hipertensos (55,4%), diabéticos (30,6%), admitidos por doenças do aparelho respiratório (42,7%); ficaram hospitalizados por mais de 15 dias (37,3%), começaram a usar sonda enteral durante a hospitalização (51,6%) por disfagia (49,7%) e permaneceram em uso de sonda até o momento da alta (65,8%). A taxa de obstrução de sonda foi de 10,4%, sendo 53,5% notificadas e 81,4% resultaram em dano moderado. Foram encontrados três fatores contribuintes relacionados à sonda enteral, cinco relacionados à nutrição enteral e oito relacionados aos medicamentos, sendo os principais, respectivamente, o posicionamento gástrico da sonda, a presença de proteína inteira na nutrição enteral e o uso de fármacos pouco ou insolúveis em água. Com relação aos eventos gastrointestinais, a taxa de diarreia foi de 63,2%, a de vômito 27,2%; a de constipação 26,2%; a de dor abdominal 16,6%; a de distensão abdominal 13,0% e a de náusea 12,7%. Conclusão: Os fatores relacionados ao paciente são os mais representativos, porém nem todos são modificáveis. Os relacionados à nutrição, em geral, estão vinculados às propriedades da própria nutrição (viscosidade, quantidade de calorias e fibras, presença de proteínas inteiras etc.), que é selecionada pelo nutricionista com base nas necessidades do paciente. Os medicamentos podem contribuir para os eventos por sua forma farmacêutica, acidez, solubilidade em água, osmolaridade, presença de sorbitol, por reação adversa, interação medicamentosa e pelo seu mecanismo de ação/classe terapêutica. Esses fatores podem ser um ponto importante a ser trabalhado em conjunto pela equipe multiprofissional. As informações geradas por este estudo poderão ser utilizadas como gatilhos, que sinalizarão pacientes mais vulneráveis e suscetíveis à ocorrência dos eventos, além de contribuírem para a tomada de decisão clínica para preveni-los

Objective: To identify and analyze factors which contribute to the occurrence of gastrointestinal events and tube obstruction in hospitalized patients using medication via enteral feeding tubes. Method: It was a cross-sectional study done with the reviewing of electronic medical records of hospitalized patients (clinical and critical) admitted in 2018 and who underwent enteral nutrition in a medium-sized and medium-complexity general public hospital in the countryside of São Paulo (Brazil), in search of adverse events and their contributing factors. Results: In 2018 there were 1735 hospitalizations, of which 386 (22.2%) met the inclusion criteria. Patients were mostly men (54.4%), elderly (72.8%), white (73.1%), primary and middle school dropouts (48.4%), underweight (35.5%), hypertensive (55.4%), diabetic (30.6%) and admitted for respiratory diseases (42.7%). The majority were hospitalized for more than 15 days (37.3%), started using enteral tubes during hospitalization (51.6%) due to dysphagia (49.7%) and remained using a feeding tube until discharge (65, 8%). Probe obstruction rate was 10.4%, with 53.5% being reported and 81.4% resulting in moderate damage. Three contributing factors were found related to the use of the device, five related to the enteral nutrition and eight related to medications, the main ones being, respectively, the gastric placement of the tube, the presence of complete protein in the diet and the use of poorly water-soluble or water-insoluble drugs. With regard to gastrointestinal events, the rate of diarrhea was 63.2%, vomiting 27.2%; constipation 26.2%; abdominal pain 16.6%; abdominal distension 13.0% and náusea 12.7%. Conclusion: The most representative contributing factors are those related to the patient, but not all are modifiable. Those related to the diet, in general, are linked to the properties of the diet itself (viscosity, number of calories and fiber, presence of complete proteins, etc.) and are selected by the nutritionist based on the patient's needs. Drugs can contribute to events for a variety of reasons: due to their pharmaceutical form, acidity, water solubility, osmolarity, presence of sorbitol, adverse reactions, drug interactions and their mechanism of action/therapeutic class. Drug-related contributing factors may be an important point to be worked on together by the multidisciplinary team. The information generated by this study can be used as trigger tools which will help identify patients who are more vulnerable and susceptible to the occurrence of adverse events, in addition to contributing to clinical decision-making to prevent them

Adoptive immunotherapy with double-bright (CD56bright /CD16bright ) expanded natural killer cells in patients with relapsed or refractory acute myeloid leukaemia: a proof-of-concept study.

Patients with acute myeloid leukaemia (AML) have a five-year survival rate of 28·7%. Natural killer (NK)-cell have anti-leukaemic activity. Here, we report on a series of 13 patients with high-risk R/R AML, treated with repeated infusions of double-bright (CD56bright /CD16bright ) expanded NK cells at an academic centre in Brazil. NK cells from HLA-haploidentical donors were expanded using K562 feeder cells, modified to express membrane-bound interleukin-21. Patients received FLAG, after which cryopreserved NK cells were thawed and infused thrice weekly for six infusions in three dose cohorts (106 -107 cells/kg/infusion). Primary objectives were safety and feasibility. Secondary endpoints included overall response (OR) and complete response (CR) rates at 28-30 days after the first infusion. Patients received a median of five prior lines of therapy, seven with intermediate or adverse cytogenetics, three with concurrent central nervous system (CNS) leukaemia, and one with concurrent CNS mycetoma. No dose-limiting toxicities, infusion-related fever, or cytokine release syndrome were observed. An OR of 78·6% and CR of 50·0% were observed, including responses in three patients with CNS disease and clearance of a CNS mycetoma. Multiple infusions of expanded, cryopreserved NK cells were safely administered after intensive chemotherapy in high-risk patients with R/R AML and demonstrated encouraging outcomes.

A PUERICULTURA NO PRIMEIRO ANO DE VIDA ­ UMA AVALIAÇÃO NA ATENÇÃO PRIMÁRIA EM SAÚDE / CHILDCARE IN THE FIRST YEAR OF LIFE-AN EVALUATION IN PRIMARY HEALTH CARE

Objetivo: avaliar a frequência de consultas no primeiro ano da criança e relacionar com as características maternas, de pré-natal e perinatais. Métodos: Coorte de crianças nascidas entre maio e outubro de 2015 que realizaram no mínimo uma consulta na Unidade Básica de Saúde até seus 13 meses incompletos. As informações maternas, de pré-natal e perinatais foram obtidas do SINASC e o número total e o tipo de consulta pelo prontuário da UBS. Foram realizadas análise descritiva das variáveis e testes de associação das características maternas, informações de pré-natal e perinatais com o número de consultas no primeiro ano. Resultados: das 237 crianças nascidas no período, 35 (14,7%) consultaram até os 13 meses incompletos (m=7,6 atendimentos). Destas, 22 (62,9%) realizaram no mínimo 7 atendimentos de puericultura. A menor escolaridade materna esteve associada a um maior número de consultas no primeiro ano de vida (p=0,050) e houve correlação do número de consultas de pré-natal com as de puericultura (p=0,044). Conclusão: o maior número de atendimentos durante o primeiro ano de vida da criança está associado à menor escolaridade materna ao mesmo tempo em que, o vínculo estabelecido durante o pré-natal, ocasionou um maior número de consultas de puericultura.

Objective: To evaluate the frequency of consultations in the first year of the child and to relate to the maternal, prenatal and perinatal characteristics.Methods: Cohort of children born between May and October 2015 who performed at least one visit to the Basic Health Unit until their 13 months. Maternal, prenatal and perinatal information were obtained from the SINASC and the total number and type of consultation by the UBS medical record. Descriptive analysis of the variables and tests of association of maternal characteristics, prenatal and perinatal information with the number of visits in the first year were performed.Results: Of the 237 children born, 35 (14.7%) consulted until the incomplete 13 months (m = 7.6 visits). Of these, 22 (62.9%) performed at least 7 childcare services. Maternal schooling was associated with a higher number of visits in the first year (p=0.050) and there was a correlation between the number of prenatal consultations and those of childcare (p = 0.044). Conclusions: The higher number of visits during the first year of life of the child is associated with lower maternal schooling, while the link established during the prenatal period has resulted in a greater number of childcare consultations.

The Effects of Neoadjuvant Chemoradiation in Locally Advanced Rectal Cancer-The Impact in Intratumoral Heterogeneity.

Purpose: Intratumoral genetic heterogeneity (ITGH) is a common feature of solid tumors. However, little is known about the effect of neoadjuvant chemoradiation (nCRT) in ITGH of rectal tumors that exhibit poor response to nCRT. Here, we examined the impact of nCRT in the mutational profile and ITGH of rectal tumors and its adjacent irradiated normal mucosa in the setting of incomplete response to nCRT. Methods and Materials: To evaluate ITGH in rectal tumors, we analyzed whole-exome sequencing (WES) data from 79 tumors obtained from The Cancer Genome Atlas (TCGA). We also compared matched peripheral blood cells, irradiated normal rectal mucosa and pre and post-treatment tumor samples (PRE-T and POS-T) from one individual to examine the iatrogenic effects of nCRT. Finally, we performed WES of 7 PRE-T/POST-T matched samples to examine how nCRT affects ITGH. ITGH was assessed by quantifying subclonal mutations within individual tumors using the Mutant-Allele Tumor Heterogeneity score (MATH score). Results: Rectal tumors exhibit remarkable ITGH that is ultimately associated with disease stage (MATH score stage I/II 35.54 vs. stage III/IV 44.39, p = 0.047) and lymph node metastasis (MATH score N0 35.87 vs. N+ 45.79, p = 0.026). We also showed that nCRT does not seem to introduce detectable somatic mutations in the irradiated mucosa. Comparison of PRE-T and POST-T matched samples revealed a significant increase in ITGH in 5 out 7 patients and MATH scores were significantly higher after nCRT (median 41.7 vs. 28.8, p = 0.04). Finally, we were able to identify a subset of "enriched mutations" with significant changes in MAFs between PRE-T and POST-T samples. These "enriched mutations" were significantly more frequent in POST-T compared to PRE-T samples (92.9% vs. 7.1% p < 0.00001) and include mutations in genes associated with genetic instability and drug resistance in colorectal cancer, indicating the expansion of tumor cell subpopulations more prone to resist to nCRT. Conclusions: nCRT increases ITGH and may result in the expansion of resistant tumor cell populations in residual tumors. The risk of introducing relevant somatic mutations in the adjacent mucosa is minimal but non-responsive tumors may have potentially worse biological behavior when compared to their untreated counterparts. This was an exploratory study, and due to the limited number of samples analyzed, our results need to be validated in larger cohorts.

Association of oxytocin levels and oxytocin receptor gene polymorphism (rs2254298) with cardiovascular risk factors in Brazilian elderly from Primary Health Care.

BACKGROUND: Morbidity and mortality from cardiovascular disease is a typical phenomenon in the elderly, and are related to unfavorable genetic, hormonal and environmental (lifestyle) interactions. In this context, oxytocin (OT) seems plays a key role in the development of CVD by performing important actions in metabolism energy and hemodynamic variables. OBJECTIVE: To verify if there is an association between (OT) levels and the oxytocin receptor gene (OXTR) polymorphism (rs2254298) with cardiovascular risk factors (CRF) in the elderly. METHODS: This was a cross-sectional study in community-dwelling elderly attending primary health care. The genotyping was done using the polymerase chain reaction technique. The CRF factors investigated included hypertension, diabetes mellitus, dyslipidemia, sedentary lifestyle, and obesity. Levels of triglycerides (TGC) postprandial and glucose were measured in capillary blood. OT and cortisol levels were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS: The sample comprised 177 elderly individuals. OT levels showed a significant negative correlation with postprandial triglycerides (p = 0.030) and BMI (p = 0.019). OT levels were also associated with leanness (p = 0.005). On Poisson regression analysis, OT remained a predictor for leanness (p = 0.010). No significant associations were observed between the OXTR polymorphism and CRF. CONCLUSION: The results suggest that Postprandial TGC levels are increased, while OT levels are decreased, and this hormone was significantly elevated in lean elderly. Future studies are needed to confirm these findings, and the role of OT in metabolic parameters.

Centesimal and mineral composition and antioxidant activity of the bacaba fruit peel / Composição centesimal, mineral e potencial antioxidante da casca do fruto de bacaba

Oenocarpus bacaba Mart. is a palm tree native from Amazon with highlighted antioxidant activities. Its fruit (bacaba) processing dismisses the peel, which has nutrients that can collaborate for its antioxidant activity and preventing diseases. Thus, this study assessed the centesimal and mineral composition, physicochemical characterization (acidity, total soluble solids, pH, and color), total phenolics (Folin-Ciocalteu method), anthocyanins and antioxidant activity by DPPH (2,2 difenil-1-picril hidrazil) method in bacaba peels. For the centesimal composition, it was found 4.87, 1.42, 29.13, 1.08 and 63.32 g 100 g-1 for water content, ashes, lipids, proteins, and total carbohydrates, respectively. For the mineral composition, it was found 582.97, 79.00, 51.79, 0.625, 37.02, 2.37 and 77.12 mg 100g-1 contents for potassium, sodium, magnesium, copper, calcium, manganese, and phosphorus, respectively. The physicochemical characterization showed pH 5.66, titratable acidity 0.306% of citric acid, total soluble solids 9,75, and coordinates L* a* e b* of 19.03, 8.07 and 9.25, respectively. Phenolic contents were 42.07 mg EAG g-1. The antioxidant potential IC50 was 1.07 mg mL-1 and anthocyanins 37.31 mg 100 g-1. Results show that bacaba peels are an alternate source of nutrients suggesting their use in food as well cosmetic industries, especially for their antioxidant activity and mineral composition

Quimiocastração com óleo essencial de Eugenia caryophyllata em cães / Canine chemical castration with Eugenia caryophyllata essential oil / Esterilización química con aceite Esencial de eugenia caryophyllata en perros

A esterilização química é uma técnica de esterilização que consiste na aplicação intratesticular de agentes esclerosantes, com o intuito de causar dano ao tecido testicular e, consequentemente, suprimir a atividade reprodutiva em animais do sexo masculino. Por ser uma técnica de rápida execução, de baixo custo e com baixos riscos de gerar complicações, vem sendo estudada como forma de esterilização em animais domésticos, especialmente pensando-se em sua utilização em larga escala. O presente estudo buscou avaliar a eficácia a médio prazo da quimiocastração com óleo essencial de cravo da índia. Doze cães adultos, sem raça definida, foram incluídos na pesquisa. Um grupo consistiu no grupo controle, o qual foi constituído de animais onde foi injetado 0,5 ml de solução fisiológica 0,9% em cada testículo, e outro, com a injeção de 0,5 mL de óleo essencial de cravo da índia em cada testículo. Foi possível observar histologicamente no grupo tratado que após 42 dias da quimiocastração houve a ocorrência de danos teciduais que geraram comprometimento da espermatogênese, o que não foi verificado no grupo controle. Apesar de o grupo tratado ter apresentado maior reação inflamatória dos testículos, as análises de cortisol e avaliação das escalas de dor permitiram constatar que não houve diferenças estatísticas entre o cortisol dos grupos controle e teste, e que a dor ocasionada pelo procedimento não atingiu um grau intenso, respectivamente. As análises bioquímicas das funções renal e hepática possibilitou verificar que, em ambos os grupos, não houve sinais de toxicidade para estes órgãos. Sendo assim, a sua utilização demonstrou-se eficaz e segura em causar supressão da atividade reprodutiva em cães machos, porém, mais estudos devem ser realizados de forma a verificar se os efeitos perduram em longo prazo.(AU)

Chemical castration is a sterilization technique consisting of intratesticular application of sclerosing agents with the intention of damaging the testicular tissue and, consequently, suppressing the reproductive activity in male animals. Since it is a fast-running, low-cost technique with low complication risks, it has been studied as a form of sterilization in pets, with special focus on a large-scale use. This study sought to evaluate the medium-term efficacy of clove essential oil as a chemical castration agent. Twelve adult dogs with no defined breed were included in the study. One group was considered the control group, which consisted of animals where 0.5 ml 0.9% saline solution was injected into each testicle. The other group was injected 0.5 ml clove essential oil in each testicle. It was possible to histologically observe in the treated group that after 42 days of the chemical sterilization there was the occurrence of tissue damages that generated spermatogenesis impairment, which was not verified in the control group. Although the treated group presented a greater inflammatory reaction of the testes, the cortisol analysis and evaluation of the pain scales showed that there were no statistical differences between the cortisol level of both groups, and that the pain caused by the procedure did not reach an intense degree, respectively. Biochemical analyzes of kidney and liver functions made it possible to verify that, in both groups, there were no signs of toxicity to these organs. Therefore, its use has been shown to be effective and safe in suppressing reproductive activity in male dogs. However, further studies should be carried out to verify if the effects persist in the long term.(AU)
