Cross-cultural adaptation of the Rotterdam Transition Profile to Brazilian Portuguese: measuring autonomy in participation of Brazilian youth with cerebral palsy.

BACKGROUND: Autonomy in participation of young adults with cerebral palsy (CP) is not well understood due to the lack of appropriate instruments, especially for the Brazilian population. The Rotterdam Transition Profile (RTP) categorizes autonomy in Participation (education, employment, finances, housing, leisure, intimate relationships, sexuality, transportation) and Health Services (care demands, services and aids, and rehabilitation services) domains. OBJECTIVES: To cross-culturally adapt the RTP for use in Brazil, and to describe the levels of autonomy in participation and associated factors of Brazilian youth with CP. METHODS: RTP was translated and content validity was investigated through an expert panel (n = 4 researchers and n = 4 clinicians); 30 adolescents and young adults with CP provided data for construct validity and internal consistency analysis. To analyze influencing factors, 56 youth with CP, mean age 25 years (SD = 6.9 years), with good cognitive level remotely responded to the RTP, sociodemographic information, and functional classifications (gross motor, manual ability). RESULTS: Following translation, content and construct validity were established, with changes made to improve the clarity of items. Cronbach's alpha (0.82) was considered good and test-reliability was fair to good for most items. High levels of autonomy were found in the areas of Leisure and Rehabilitation, with the lowest proportion of participants with autonomy in Housing, Intimate Relationships, and Finances. Autonomy in participation was associated with age, gross motor and manual ability classifications, and with context-related factors. CONCLUSION: The Brazilian Portuguese version of the RTP was considered valid and reliable. Findings will support transition planning for young people with CP.

Looking beyond Body Structure and Function: ICF Foci and Who Is Being Assessed in Research about Adolescents and Young Adults with Cerebral Palsy-A Scoping Review.

PURPOSE: The purpose of this study is to summarize the ICF foci, looking beyond body structures and function, and to analyze who has been assessed in research about adolescents and young adults (AYAs) with CP in the phase of transition to adulthood. METHOD: Medline, EMBASE, PsycINFO, and CINAHL databases were searched using terms related to cerebral palsy, adolescents/young adults, health development, participation, and independence. Studies including youth with CP (13-30 years old) published in English from 2014 to 2021 were considered. The methods of assessment reported in the included studies were used to identify the ICF foci and who was assessed. RESULTS: In this study, 86 studies were reviewed. The main ICF foci are activity and participation (51% of the studies), personal factors (23%), ICF not covered (14%), ICF not defined (9%), with environmental factors being the least focused ICF component (3%). Most studies assessed AYAs directly (49% of studies). CONCLUSIONS: Activity- and participation-related constructs are the leading research focus of studies, and more attention is needed concerning environmental factors. AYAs are the main source of information, and the perspectives of other key figures are also being valued. To bridge the gap between child and adult health care, a broader view of health development and approaches to explore AYA developmental issues must be taken.

Clear Cell Papillary Renal Cell Tumors: A Study of 42 Tumors with Emphasis on the Fibrous Capsule, Cystic Component, and GATA3 Immunohistochemistry.

Clear cell papillary renal cell tumor is a common and sometimes underdiagnosed renal cell neoplasm. Its proper recognition is important because its diagnosis implies a remarkably high probability of indolent behavior. This study aimed to evaluate the frequency of a fibrous capsule, a cystic component, and a GATA3 expression in clear cell papillary renal cell tumors. We assessed 419 renal cell neoplasms from three institutions located in northeastern Brazil and identified 42 clear cell papillary renal cell tumors (from 39 patients), which were the fourth most common renal cell neoplasm. These tumors commonly exhibited fibrous capsules (all showed complete or partial capsules) and cystic component (93%). Eighteen out of 42 tumors (43%) showed some expression of GATA3, and weak and focal staining was common among the positive tumors. Clear cell papillary renal cell tumor must always be included in the differential diagnosis of predominantly cystic renal cell neoplasms. As GATA3 is inconsistently expressed in clear cell papillary renal cell tumors, it is not useful in this diagnosis.

Interrelationships of Touch and Proprioception with Motor Impairments in Individuals with Cerebral Palsy: A Systematic Review.

Considering that somatosensory impairments may impact motor performance in individuals with cerebral palsy (CP), a better understanding of these relations is relevant to planning interventions. To synthesize research evidence to date on the interrelationships between the somatosensory functions of touch and proprioception with motor functions in persons with CP, we systematically searched Embase, CINAHL, PsycINFO, and Medline databases for studies relating these variables that were published in English from the inception of these databases to November 2020. We targeted the following content categories in our literature search: (a) cerebral palsy; (b) sensory functions; (c) tactile functions; (d) proprioception functions; and (e) motor functions. The selection, data extraction, and methodological quality assessment of these studies were performed in duplicate. We retrieved and analyzed information regarding the studies' methodological approaches and synthesized results. The 11 studies that met our inclusion criteria showed that, in individuals with CP, impairments in tactile discrimination, proprioception, and stereognosis are related to motor functions in terms of overall manual ability, grip strength, postural control and locomotion. Thus, clinical practitioners should attend to somatosensory aspects of motor impairment in individuals with CP. More research is needed to clarify the direction of these associations.

Co-Design of an Intervention to Increase the Participation in Leisure Activities Including Adolescents with Cerebral Palsy with GMFCS Levels IV and V: A Study Protocol.

The participation of adolescents with cerebral palsy (CP) within the community is reduced compared to their peers and is a barrier to their socialization, self-determination and quality of life. Patient and Public Involvement (PPI) is a key strategy for successful interventions, especially when involvement of the stakeholders takes place at all stages of the research. Co-design can be crucial for success as researchers, patients with CP and their families work together to bring the necessary elements to the interventions to be designed. The objectives will be: (1) To co-design an intervention aimed at improving the participation of adolescents with significant motor disabilities within the community in partnership with adolescents with CP, families and rehabilitation professionals. (2) To assess the feasibility of the co-design process in partnership with interested parties. The study will be based on Participatory Action Research (PAR) and will be held in Spain and Brazil. In both countries, the study will be carried out remotely with nine adolescents aged 12 to 17 years with CP, Gross Motor Function Classification System (GMFCS) levels IV-V, their families and six health professionals (physiotherapists and occupational therapists). Different dialogue groups will be created to involve adolescents, families and health professionals to the research's project. To manage their involvement in the co-design process, the Involvement Matrix (IM) will be used, and according to the IM phases, four steps will be included in the research: (1) Preparation; (2) Co-design; (3) Analysis: results of the intervention protocol and the study's feasibility and (4) Dissemination of results. Partnering with the public to design an intervention to improve participation can bring better results compared to protocols designed only by health professionals. In addition, it will allow for knowing the needs of adolescents with CP in terms of participation within the community. The study will also explore which roles were chosen by all participants and how they felt while actively participating in the process of co-designing an intervention protocol and their own perspectives on the use of the involvement matrix.

Varizes mamárias promovendo limitação no diagnóstico do câncer de mama bilateral, associado a trombose mamária: um relato de caso / Breast varices limiting diagnosis of bilateral breast cancer, associated with breast thrombosis: a case report

Varizes mamárias bilaterais e simétricas são entidades raras, que são geralmente decorrentes de síndrome da veia cava superior. O mecanismo desta síndrome é a obstrução crônica do fluxo sanguíneo da veia cava superior para o átrio direito. Este é o relato do caso de uma paciente idosa que apresentava varizes em ambas as mamas e que apresentou câncer de mama bilateral. Várias peculiaridades chamam a atenção neste caso. Uma delas é que as varicosidades limitaram a visualização de pelo menos um dos nódulos pela mamografia, e podem ter contribuído para a demora do seu diagnóstico. Outra foi o desenvolvimento do câncer de mama bilateral, que tem uma incidência bem menor do que o unilateral. E, por último, houve o desenvolvimento de trombose venosa nas varizes de ambas as mamas. A trombose venosa é uma possível complicação de vários tipos de neoplasias, porém sua associação ao câncer de mama é rara. Não encontramos na literatura científica descrição de trombose localizada nas mamas em pacientes com câncer

Bilateral and symmetrical breast varices are rare entities and usually result from superior vena cava syndrome. This syndrome develops due to chronic obstruction of blood flow from the superior vena cava to the right atrium. This article reports a case of an elderly patient who had varicose veins in both breasts, and who had bilateral breast cancer. This case has several peculiarities. One of them is that varicosities limited the visualization of at least one of the nodules on mammography, and may have contributed to the delay in its diagnosis. Another one was the development of bilateral breast cancer, which has a much lower incidence than unilateral. And finally, there was the development of venous thrombosis in the varicose veins of both breasts. Venous thrombosis is a possible complication of several types of neoplasms, but its association with breast cancer is rare. We could not find in scientific literature descriptions of breast thrombosis in patients with cancer.

Lower muscular strength is associated with smaller left and right chambers and lower cardiac mass in the general population - The Sedentary's Heart.

BACKGROUND: The cardiac muscle has the ability to adapt to different loading conditions. We analyzed the associations of the age-related decreasing handgrip strength (HGS), a marker of muscular fitness, on cardiac structure and function in a community-based sample. METHODS: We performed cross-sectional analyses of 4646 subjects (2554 women; 55.0%) aged 20 to 93 years from two independent cohorts of the Study of Health in Pomerania (SHIP-2 and SHIP-TREND-0). We analyzed the associations of HGS with structural and functional left and right ventricular (LV and RV) and left atrial (LA) parameters as determined by echocardiography and magnetic resonance imaging (MRI) as well with log-transformed NT-proBNP values using multivariable-adjusted linear regression models. RESULTS: MRI data showed that a 1 kg lower HGS was associated with a 0.40 mL (95% confidence interval: 0.26 to 0.54; p < 0.001) lower LV end-diastolic volume, a 0.011 mm (0.005 to 0.018; p = 0.001) lower LV wall-thickness, a 0.59 g (0.43 to 0.75; p < 0.001) lower LV mass, a 0.58 mL/beat (0.43 to 0.74; p < 0.001) lower LV stroke volume, a 0.03 L/min (0.02 to 0.04; p < 0.001) lower LV cardiac output, a 0.48 mL (0.27 to 0.68; p < 0.001) lower LA end-diastolic volume, and a 1.02 mL (0.71 to 1.32) lower RV end-diastolic volume. Similar findings were observed for echocardiographic parameters. Moreover, lower HGS was associated with higher echocardiographic LV diastolic stiffness and NT-proBNP levels. CONCLUSIONS: In this large population-based sample, lower muscular fitness as assessed by HGS was associated with lower LV wall thickness and mass as well as with smaller chamber size, stroke volume and cardiac output of the LV, LA and RV. Moreover, HGS was inversely related to LV diastolic stiffness and NT-proBNP values. These outcomes might demonstrate the effects of an aging-related decrease in physical activity and lower muscular fitness on the heart - "the sedentary's heart".

Lower Limb Sensorimotor Training (LoSenseT) for Children and Adolescents with Cerebral Palsy: A Brief Report of a Feasibility Randomized Protocol.

Motor disorders in cerebral palsy (CP) are often accompanied by disturbances of sensation and impaired somatosensory functions have been reported in individuals with CP. To test the feasibility of a sensorimotor training protocol for lower limbs in children and adolescents with unilateral and bilateral CP, and to analyze the preliminary effects of this training on sensory and motor variables. This is a single-blind, prospective phase I feasibility randomized protocol. A total of twenty participants with uni or bilateral cerebral palsy, GMFCS level I-III, ages 5 to 20 years will be recruited. The LoSenseT protocol is composed of tactile and proprioceptive activities in a child-friendly format. An original qualitative feedback questionnaire was developed to assess the protocol feasibility. Additionally, proprioception, tactile discrimination, postural stability, and gait parameters will be assessed. The LoSenseT protocol can support the implementation of interventions targeting lower limbs somatosensory impairments in individuals with CP.

Positive psychology interventions to improve well-being and symptoms in people on the schizophrenia spectrum: a systematic review and meta-analysis.

OBJECTIVE: Positive psychology interventions (PPIs) incorporate principles of personal strengths with the view that mental health recovery transcends symptom relief. Severe psychiatric conditions, such as schizophrenia, may benefit from such interventions. This study aims to gather the current evidence on the impact of PPIs on increasing well-being in patients on the schizophrenia spectrum and assess reductions in negative or positive symptoms. METHODS: A systematic review of PPI studies with schizophrenia-spectrum patients was carried out following PRISMA recommendations. The PubMed, PsycINFO, Web of Science, and Scopus databases were searched for relevant publications in order to understand the possible effects of these interventions on well-being measures and psychotic symptoms in this population. RESULTS: Nine studies (four controlled) were included. Meta-analysis of the controlled studies showed a significant effect (p = 0.04) for improvement of well-being (Z = 2.01). Overall, the reviewed evidence suggests well-being improvement. The effect on reduction of negative symptoms was unclear. CONCLUSION: Used as an adjunctive therapy, PPIs appear to be a promising resource for patients on the schizophrenia spectrum, with possible effects on well-being and symptom reduction.

Subjective well-being, religiosity and anxiety: a cross-sectional study applied to a sample of Brazilian medical students.

OBJECTIVE: To assess associations between subjective well-being (SWB), religiosity, anxiety and other factors in a sample of Brazilian medical students from a public university in northeastern Brazil. METHODS: The present study followed a cross-sectional, observational, analytical approach. Data were collected by administering a self-applicable questionnaire composed of questions focused on sociodemographic data and based on the Satisfaction With Life Scale (SWL), Positive Affect and Negative Affect Scale (PANAS), Penn State Worry Questionnaire (PSWQ), and the Duke Religiosity Index (DUREL). RESULTS: The sample comprised 417 medical school students (73.54% of all the enrolled students). The medical students assessed presented a medium level of satisfaction with life, low mean positive emotion levels and high anxiety/uneasiness levels. Surprisingly, lower anxiety and intrinsic religiosity (IR) scores were associated with higher scores in the two SWB parameters (positive emotions and satisfaction with life). Furthermore, the factors leisure activities, good sleep quality, financial support, age, and gender were associated with the highest SWB scores (with emotional and cognitive components, or with only one of these two components). CONCLUSIONS: Data in the current study corroborated the negative association between SWB and anxiety; however, in opposition to the literature, they also evidenced a negative association between SWB and IR. In addition, the present research signaled the need for creating preventive intervention programs to increase SWB through positive psychological techniques and/or to decrease anxiety by applying, for instance, cognitive-behavioral therapy paradigms and/or mindfulness techniques to medical students.

Resumo Objetivos: Avaliar associações entre bem-estar subjetivo (BES), religiosidade, ansiedade e outros fatores em uma amostra de estudantes brasileiros de medicina de uma universidade pública do nordeste do Brasil. Métodos: O presente estudo seguiu uma abordagem transversal, observacional, analítica. Os dados foram coletados por meio da aplicação de um questionário autoaplicável incluindo questões focadas em dados sociodemográficos e baseado na Escala de Satisfação com a Vida (SWL), Escala de Afeto Positivo e Afeto Negativo (PANAS), Questionário de Preocupação da Pensilvânia (PSWQ) e Índice de Religiosidade de DUKE (DUREL). Resultados: A amostra foi composta por 417 estudantes de medicina (73,54% de todos os alunos matriculados). Os estudantes avaliados apresentaram nível médio de satisfação com a vida, baixos níveis de emoções positivas e altos níveis de ansiedade/preocupação. Surpreendentemente, menor ansiedade e escores de religiosidade intrínseca (IR) foram associados com maiores pontuações nos dois parâmetros de BES (emoções positivas e satisfação com a vida). Além disso, os fatores atividades de lazer, boa qualidade do sono, apoio financeiro, idade e sexo foram associados aos maiores escores do BES (com componentes emocionais e cognitivos, ou apenas um deles). Conclusão: Os dados do presente estudo corroboraram a associação negativa entre BES e ansiedade; no entanto, contrariamente à literatura, eles também evidenciaram uma associação negativa entre BES e IR. Além disso, a presente pesquisa sinalizou a necessidade de criar programas de intervenção preventiva para aumentar o BES por meio de técnicas psicológicas positivas e/ou diminuir a ansiedade aplicando, por exemplo, paradigmas de terapia cognitivo-comportamental e/ou técnicas de mindfulness a estudantes de medicina.

Chemical composition of essential oil from Myrcia oblongata DC and potencial antimicrobial, antioxidant and acaricidal activity against Dermanyssus gallinae (Degeer, 1778) / Composição química do óleo essencial de Myrcia oblongata DC e potencial antimicrobiano, antioxidante e acaricida contra Dermanyssus gallinae (DEGEER, 1778)

Essential oils have aroused interest in the industrial sector due to the multitude of potential applications, especially with respect their antimicrobial and antioxidant properties, among others. The objective of this study was to determine the chemical composition of the essential oil from the leaves of Myrcia oblongata DC by gas chromatography coupled to mass spectrometry (GC-MS). To evaluate the antioxidant potential of the oil by using the free radical capture method with 2,2-diphenyl-1-picryl hydrazyl (DPPH); to test the oil antimicrobial activity using the broth microdilution method; and to evaluate the repellency and fumigant potential of the oil on Dermanyssus gallinae (Degeer, 1778). The GC-MS analysis resulted in the identification of 30 oil constituents, with the bulk of the composition identified as caryophyllene oxide (22.03%) and trans-verbenol (11.94%). The oil presented moderate antioxidant activity compared to the synthetic antioxidant 2,6-di-tert-butyl-4-hydroxytoluene (BHT). Antimicrobial activity of the essential oil showed an inhibitory activity on Gram-positive bacteria, Enterococcus faecalis, Staphylococcus aureus, Bacillus subtilis and Staphylococcus epidermidis and for the yeast Candida albicans, and showed no activity against Gram-negative bacteria. All concentrations of the essential oil used in the fumigation test on D. gallinae resulted in mortality below 20%. For the repellency test, significant potential was observed for the concentration of 10%.

Os óleos essenciais tem despertado interesse no setor industrial por apresentarem multiplicidade de aplicações, destacando-se por suas propriedades antimicrobianas, antioxidantes dentre outras. Diante disto, o objetivo deste estudo foi determinar a composição química do óleo essencial das folhas de Myrcia oblongata DC pelo método de cromatografia gasosa acoplada à espectrometria de massas (CG-EM), avaliar o potencial antioxidante do óleo pelo método de captura do radical livre 2,2- difenil-1-picril hidrazil (DPPH), testar a atividade antimicrobiana pelo método de microdiluição em caldo, bem como avaliar a repelência e potencial fumigante deste óleo sobre Dermanyssus gallinae (Degeer, 1778). As análises de CG-EM resultaram na identificação de 30 constituintes, sendo majoritários o óxido de cariofileno (22.03%) e o trans-verbenol (11.94%). O óleo apresentou atividade antioxidante moderada quando comparada ao antioxidante sintético 2,6-di-tert-butil-4-hidroxitolueno (BHT). Em relação à atividade antimicrobiana, o óleo essencial demonstrou atividade inibitória para as bactérias Gram-positivas, Enterococcus faecalis, Staphylococcus aureus, Bacillus subtilis e Staphylococcus epidermidis, e para levedura Candida albicans e não apresentou atividade para bactérias Gram negativas. Todas as concentrações do óleo essencial testadas no teste de fumigação sobre D. gallinae apresentaram mortalidade inferior a 20%. Para o teste de repelência, observou-se um potencial significativo para a concentração de 10%.

Surveillance of vector-borne pathogens under imperfect detection: lessons from Chagas disease risk (mis)measurement.

Vector-borne pathogens threaten human health worldwide. Despite their critical role in disease prevention, routine surveillance systems often rely on low-complexity pathogen detection tests of uncertain accuracy. In Chagas disease surveillance, optical microscopy (OM) is routinely used for detecting Trypanosoma cruzi in its vectors. Here, we use replicate T. cruzi detection data and hierarchical site-occupancy models to assess the reliability of OM-based T. cruzi surveillance while explicitly accounting for false-negative and false-positive results. We investigated 841 triatomines with OM slides (1194 fresh, 1192 Giemsa-stained) plus conventional (cPCR, 841 assays) and quantitative PCR (qPCR, 1682 assays). Detections were considered unambiguous only when parasitologists unmistakably identified T. cruzi in Giemsa-stained slides. qPCR was >99% sensitive and specific, whereas cPCR was ~100% specific but only ~55% sensitive. In routine surveillance, examination of a single OM slide per vector missed ~50-75% of infections and wrongly scored as infected ~7% of the bugs. qPCR-based and model-based infection frequency estimates were nearly three times higher, on average, than OM-based indices. We conclude that the risk of vector-borne Chagas disease may be substantially higher than routine surveillance data suggest. The hierarchical modelling approach we illustrate can help enhance vector-borne disease surveillance systems when pathogen detection is imperfect.

Intervenção de saúde positiva em graduação de medicina / Positive health intervention in medical graduation

Introdução: A prevalência de transtornos mentais em estudantes de medicina é globalmente alta e esse grupo tende a ter estratégias de enfrentamento mais perigosas. Revisões sistemáticas trouxeram suporte científico para a realização de intervenções que visam melhorar o bem-estar e a saúde mental dos estudantes de medicina. O presente artigo traz a análise dos relatos fornecidos pelos estudantes de medicina da Universidade Federal de Pernambuco que participaram de um treinamento emocional baseado na psicologia positiva, uma área da psicologia fundada na década de noventa que visa estudar o bem-estar e as potencialidades humanas, afim de ampliar a avaliação da intervenção. Relato da experiência: Inicialmente, os alunos se apresentaram surpresos em relação à abordagem nova. A surpresa se deveu à dinâmica em si, mas também ao fato de desconhecerem a psiquiatria positiva e a psicologia positiva, abordagens que visam o estudo e a promoção da saúde mental positiva por meio de fatores vinculados ao bem-estar. Antes da intervenção, cerca de 32,3% dos estudantes tinham escore de risco para transtornos mentais comuns, conforme aferição realizada pela escala Self-Reporting Questionnaire (SRQ-20). E, apesar da estranheza inicial, tanto os que estavam com alguma condição psiquiátrica, quanto os que não estavam, sentiram benefício direto da intervenção que focou na saúde mental positiva. Conclusão: A análise dos relatos dos estudantes de medicina da Universidade Federal de Pernambuco que receberam uma intervenção focada em estimular aspectos da saúde mental positiva por meio da psicologia positiva complementa o entendimento dos resultados quantitativos encontrados em publicação prévia. Tanto os alunos que estavam com alguma condição psiquiátrica no momento da intervenção, quanto os que não estavam, sentiram benefício direto da intervenção que focou na saúde mental positiva. Houve também percepção de que a intervenção influenciou positivamente a formação médica deles e não somente a saúde mental.

Introduction: The prevalence of mental disorders in medical students is globally high and this group tends to have more dangerous coping strategies. Systematic reviews have provided scientific support for interventions aimed at improving the well-being and mental health of medical students. This article presents the analysis of the reports provided by the medical students of the Federal University of Pernambuco who participated in an emotional training based on positive psychology, an area of psychology founded in the nineties that aims to study human well-being and potentialities, in order to extend the evaluation of the intervention. Experience report: Initially, students were surprised at the new approach. The surprise was due to the dynamics themselves, but also to the fact that they are unaware of positive psychiatry and positive psychology, approaches aimed at the study and promotion of positive mental health through factors linked to well-being. Before the intervention, about 32.3% of the students had a risk score for common mental disorders, as measured by the Self-Reporting Questionnaire (SRQ-20). And despite this initial strangeness, both those with some psychiatric condition and those who were not felt direct benefit from the intervention that focused on positive mental health. There was also a perception that the intervention positively influenced their medical education and not only their own mental health, with the wish that the training had taken place before the course. Conclusion: The analysis of the reports of medical students from the Federal University of Pernambuco who received an intervention focused on stimulating aspects of positive mental health through positive psychology complement the understanding of the quantitative results found in a previous publication. Both students who were in some psychiatric condition at the time of the intervention, as well as those who were not, felt direct benefit from the intervention that focused on positive mental health. There was also a perception that the intervention positively influenced their medical education and not just their own mental health.
