Hair collection protocol in 12-month-old infants.

Purpose: Most studies assessing hair cortisol were conducted with adults. As specific guidelines for infant hair collection are lacking, we developed a hair collection protocol for 12-month-old infants and assessed its acceptability and feasibility. Results: Out of the total (N = 45), 95.6 % (n = 43) of caregivers consented to the procedure, while one caregiver did not consent (2.2 %), and another requested the procedure to be halted before required amount of hair had been reached (2.2 %). Furthermore, two (4.4 %) infants did not have enough hair for collection. There was no attrition due to infant fussiness/crying. Discussion: We learned five lessons which can help to enhance reproducibility, mother's consent, and mother-infant comfort and acceptance of the procedure. The first lesson is to have the infant sit on the caregiver's lap to ensure the infant feels safe and remains relatively still. The second is to reassure caregivers by showing hair samples representing the amount to be cut as well as by clarifying no unaesthetic gaps would be visible. The third is to caress the infant's head to habituate them to the hair manipulation and to make soap bubbles as distractors. The fourth is to take extra care when securing the lock of hair for cutting because the infant scalp is thin and malleable. The fifth is to place a precision scale in the collection room to ensure the necessary weight is reached. Conclusion: Our hair collection protocol developed for 12-month-old infants was deemed feasible and acceptable, filled an important literature gap concerning the absence of published protocols for infants, and will contribute to increase the replicability and collection efficiency for other research teams.

Clinical comparison of whitening efficacy and tooth sensitivity of different concentrations of hydrogen peroxide photoactivated with violet or blue LEDs.

This study evaluated the photoactivation of hydrogen peroxide gels at different concentrations using blue or violet LED in terms of whitening efficacy and tooth sensitivity. Forty patients were randomly divided into 4 groups: HP6V (violet LED and 6% hydrogen peroxide), HP6B (blue LED and 6% hydrogen peroxide), HP35V (violet LED and 35% hydrogen peroxide), and HP35B (blue LED and 35% hydrogen peroxide). The L*, a* and b* values were measured before, 1 week and 3 months after treatment, and the ΔE and ΔWID values were calculated. Tooth sensitivity was measured using a visual analogue scale (VAS) before, immediately after, and 24 h after bleaching. The ΔE, ΔWID and bleaching sensitivity values were subjected to the ANOVA test and Bonferroni post-test. HP35V and HP35B showed higher whitening efficacy than HP6VL, while HP6V did not show statistical differences compared to the other groups. Regarding bleaching-related sensitivity, the HP6V and HP6B groups presented the lowest values when compared to HP35V and HP35B. HP6V showed whitening efficacy comparable to HP35V and HP35B but with reduced tooth sensitivity. TRIAL REGISTRATION NUMBER: NCT06165458; registration date: 12/09/2023.

Knowledge of the workers of the construction industry about acquired immunodeficiency syndrome and associated factors.

BACKGROUND: Sexually Transmitted Infections (STIs), such as Human Immunodeficiency Virus (HIV) transmitted by biological, socioeconomic and cultural factors that increase the vulnerability of certain population groups such as civil construction workers. OBJECTIVE: To evaluate the knowledge of workers in the construction industry about infection by HIV and associated factors. METHODS: A cross-sectional, analytical study was conducted, including 381 construction workers, in the cities of João Pessoa, Cabedelo, and Santa Rita, in the State of Paraíba, Brazil, performed through interviews, using a data collection instrument with social demographic variables and the HIV Knowledge Questionnaire. Data were analyzed using descriptive measures, and for comparison between the categories the Kruskal-Wallis test was used, with margin of error of 5% . RESULTS: A predominance of male workers was observed (97.4%) among 381 workers; aged 30-39 (34.1%); married (81.4%); with up to eight years of education (66.6%); family income of up to 2x the minimum wage (52.8%) and coming from the country (43.8%). The average of correct responses was 63.3%, with higher indices (70.0%) related to transmission and forms of prevention. There were higher percentages of hits among those who had studied for 12 years or more. Workers from the capital of Paraíba presented a higher number of correct responses (67.44%). CONCLUSIONS: There is a low index of knowledge of construction workers about HIV, highlighting their consequent vulnerability to acquiring this infection.

Avaliação e Ensino de Emoções com Crianças e Jovens Adultos com Autismo ou Síndrome de Down Mediado pela Família / Assessment and Teaching of Emotions with Children and Young Adults with Autism or Down Syndrome Mediated by Family / Evaluación y Enseñanza de las Emociones con Niños y Jóvenes con Autismo o Síndrome de Down Mediadas por la Familia

Resumo: Este estudo avaliou o reconhecimento (imitação, identidade e identificação) e a nomeação de estímulos emocionais de valência negativa (raiva e tristeza) e positiva (alegria e surpresa) em conjunto com a influência dos tipos de estímulos utilizados (social-feminino, social-masculino, familiar e emoji) em crianças e jovens adultos com autismo ou síndrome de Down, por meio de tarefas aplicadas pela família e mediadas por recursos tecnológicos durante a pandemia de covid-19. Participaram cinco crianças e dois jovens adultos com autismo e uma criança e dois jovens adultos com síndrome de Down. Foram implementadas tarefas de identidade, reconhecimento, nomeação e imitação, com estímulos faciais de função avaliativa (sem consequência diferencial) e de ensino (com consequência diferencial, uso de dicas e critério de aprendizagem), visando a emergência da nomeação emocional por meio do ensino das tarefas de reconhecimento. Os resultados da linha de base identificaram que, para os participantes que apresentaram menor tempo de resposta para o mesmo gênero, a diferença de tempo de resposta foi em média 57,28% menor. Em relação à valência emocional, 50% dos participantes apresentaram diferenças nos acertos, a depender da valência positiva e negativa, sendo que 66,66% apresentaram diferenças para o tempo de resposta a depender da valência emocional. Após o procedimento de ensino, os participantes mostraram maior número de acertos nas tarefas, independentemente do gênero de estímulo e valência emocional, criando ocasião para generalização da aprendizagem de reconhecimento e nomeação de emoções, além de consolidar a viabilidade de estratégias de ensino mediadas por recursos tecnológicos e aplicadas por familiares.

Abstract: This study evaluated the recognition (imitation, identity, and identification) and naming of negative (anger and sadness) and positive (joy and surprise) emotional stimuli alongside the influence of the types of stimuli (social-female, social-male, family, and emoji) in children and young adults with autism and Down syndrome, via tasks applied by the family and mediated by technological resources, during the COVID-19 pandemic. Five children and two young adults with autism and one child and two young adults with Down syndrome participated. Identity, recognition, naming, and imitation tasks were planned and implemented using facial stimuli with evaluative (without differential consequence) and teaching (with differential consequence, tips, and learning criteria) functions, aiming at the emergence of emotional naming from the recognition teaching tasks. The baseline results showed that, for participants who had a shorter response time for the same gender, the response time difference was on average 57.28% lower. Regarding the emotional valence, 50% of the participants showed differences in the correct answers, depending on the positive and negative valence, and 66.66% showed differences in the response time depending on the emotional valence. After the teaching procedure, the participants showed a greater number of correct answers in the tasks, regardless of the stimulus type and emotional valence, creating an opportunity for generalizing learning of emotion recognition and naming, in addition to consolidating the feasibility of teaching strategies mediated by technological resources and applied by family members.

Resumen: Este estudio evaluó el reconocimiento (imitación, identidad e identificación) y la denominación de estímulos emocionales negativos (enfado y tristeza) y positivos (alegría y sorpresa) y la influencia de los tipos de estímulos utilizados (social-femenino, social-masculino, familiar y emoji ) de niños y jóvenes con autismo o síndrome de Down, a través de tareas aplicadas por la familia, mediadas por recursos tecnológicos durante la pandemia de la covid-19. Participaron cinco niños y dos adultos jóvenes con autismo, y un niño y dos adultos jóvenes con síndrome de Down. Se planificaron e implementaron tareas de identidad, reconocimiento, nombramiento e imitación con estímulos faciales con función evaluativa (sin consecuencia diferencial) y enseñanza (con consecuencia diferencial, uso de ayudas y criterios de aprendizaje), buscando la emergencia del nombramiento emocional después de la enseñanza de tareas de reconocimiento. Los resultados de la línea de base identificaron que para los participantes que tenían un tiempo de respuesta más corto para el mismo género, la diferencia en el tiempo de respuesta fue un 57,28% menor. En cuanto a la valencia emocional, el 50% de los participantes mostraron diferencias en las respuestas correctas, en función de la valencia positiva y negativa, y el 66,66% tuvieron diferencias en el tiempo de respuesta, en función de la valencia emocional. Después del procedimiento de enseñanza, los participantes mostraron mayor número de aciertos en las tareas evaluadas, independientemente del tipo de estímulo o valencia emocional, lo que genera una oportunidad para la generalización del aprendizaje de reconocimiento y denominación de emociones, además de consolidar la viabilidad de estrategias de enseñanza mediadas por recursos tecnológicos y aplicadas por la familia.

Visita domiciliar multiprofissional: estratégia de promoção do cuidado materno-infantil no puerpério / Multiprofessional home visiting: a strategy to promote mother-child care in the puerperium period

A visita domiciliar puerperal consiste em uma das atividades inerentes à Estratégia de Saúde da Família e se caracteriza como um importante instrumento de intervenção no contexto familiar. A abordagem multiprofissional e interdisciplinar no contexto domiciliar tem se mostrado uma estratégia positiva, que promove a atenção integral, facilita o cuidado e o vínculo e proporciona aos profissionais conhecer a realidade em que a família está inserida. Diante do exposto, este artigo objetiva relatar a experiência de profissionais de saúde residentes em Saúde da Família e Comunidade dos núcleos profissionais de enfermagem, nutrição e odontologia em visitas puerperais. Foram realizadas doze visitas domiciliares às puérperas e aos RN no município de Iguatu-CE, durante o período de novembro de 2018 a março de 2019. Durante as visitas, foram realizadas condutas clínicas voltadas à puérpera e ao recém-nascido, além do repasse de orientações e cuidados, de forma a promover saúde e prevenir agravos. A inserção da equipe multiprofissional nas visitas puerperais foi uma experiência de grande relevância tanto para as profissionais de saúde como para os pacientes, pois possibilitou, através da educação em saúde, a ampliação do cuidado com a saúde materno-infantil, o fornecimento de orientações e, com isso, a melhoria da qualidade de saúde e de vida da população atendida com esta prática.

The postpartum home visit consists of one of the activities inherent in the Family Health Strategy and it is featured as an important intervention instrument in the family context. The multiprofessional and interdisciplinary approach in the home context has been shown to be a positive strategy that promotes integral care, facilitates care and bonding, and allows professionals to know the reality in which the family is inserted. Considering the above, this paper aims to report the experience of resident health professionals in Family and Community Health of the professional nuclei of nursing, nutrition and dentistry in puerperal visits. Twelve home visits were conducted to puerperal and newborn infants in the municipality of Iguatu-CE during the period from November 2018 to March 2019. During the visits, clinical procedures were performed for the puerperal woman and the newborn, as well as the transfer of guidelines and care, in order to promote health and prevent diseases. The inclusion of the multiprofessional team in the puerperal visits was an experience of great value for both health professionals and patients, because it enabled through health education, the expansion of maternal and child health care, the provision of guidelines and thereby improving the quality of health and life of the population assisted with this practice.

Long-term Ecological Research: Chasing fashions or being prepared for fashion changes?

Long-term-ecological-research (LTER) faces many challenges, including the difficulty of obtaining long-term funding, changes in research questions and sampling designs, keeping researchers collecting standardized data for many years, impediments to interactions with local people, and the difficulty of integrating the needs of local decision makers with "big science". These issues result in a lack of universally accepted guidelines as to how research should be done and integrated among LTER sites. Here we discuss how the RAPELD (standardized field infrastructure system), can help deal with these issues as a complementary technique in LTER studies, allowing comparisons across landscapes and ecosystems and reducing sampling costs. RAPELD uses local surveys to understand broad spatial and temporal patterns while enhancing decision-making and training of researchers, local indigenous groups and traditional communities. Sampling of ecological data can be carried out by different researchers through standardized protocols, resulting in spatial data that can be used to answer temporal questions, and allow new questions to be investigated. Results can also be integrated into existing biodiversity networks. Integrated systems are the most efficient way to save resources, maximize results, and accumulate information that can be used in the face of the unknown unknowns upon which our future depends.

Validation of an Innovative Chromatographic Method for Hypericin Quantification in Nanostructured Lipid Carriers.

BACKGROUND: Hypericin (HYP) is a natural compound widely used as a food supplement. The encapsulation of HYP into nanosystems, such as nanostructured lipid carriers (NLC), is a promising strategy for delivering this lipophilic molecule and protecting it from degradation. OBJECTIVE: This study aims to develop and validate an analytical method to quantify the encapsulation efficiency of HYP in NLC. METHOD: A reverse-phase high-performance liquid chromatography (HPLC) method was developed and validated according to the International Conference on Harmonization (ICH) guide Q2 (R1). NLC was prepared through the ultrasonication method, and HYP encapsulation efficiency was evaluated using the validated method. RESULTS: Separation was achieved using an isocratic mobile phase composed of acetonitrile, methanol, and ammonium acetate buffer (10 mM, pH 5.0) (54:36:10, v/v/v) and a reverse stationary phase. The specificity, linearity, precision, accuracy, and robustness of the method were assessed and confirmed during the validation. Furthermore, the validated method was able to determine the encapsulation efficiency of HYP in NLC. CONCLUSIONS: The HPLC method was validated, and the results indicated the ability of NLC to deliver HYP compounds for further application as a food supplement. HIGHLIGHTS: HYP is used as a food supplement and for photodynamic therapy (PDT). The developed method was specific, linear, precise, accurate, and robust. NLCs showed a high ability to encapsulate HYP.

Prevalence and predictors of chronic thromboembolic pulmonary hypertension following severe forms of acute pulmonary embolism.

INTRODUCTION AND OBJECTIVES: The true prevalence of chronic thromboembolic pulmonary hypertension (CTEPH) after pulmonary embolism (PE) in the Portuguese population remains unknown. We aimed to assess the prevalence and predictors of CTEPH two years after a symptomatic high- (HR) or intermediate-high risk (IHR) PE. METHODS: We conducted a retrospective cohort study of patients admitted with PE between 2014 and 2019 to a Portuguese referral center for pulmonary hypertension. RESULTS: In this single-center registry of 969 patients admitted with PE (annual incidence of 46/100000 population), 194 had HR (5.4%) and IHR (14.7%) PE. After excluding patients who died or had no follow-up in the first three months, 129 patients were included in the analysis. The overall prevalence of suspected CTEPH by clinical assessment, Doppler echocardiography and V/Q lung scan was 6.2% (eight patients). CTEPH was confirmed by right heart catheterization in four of these (3.1%). Increased pulmonary artery systolic pressure (PASP) at admission (OR 1.12; 95% CI 1.04-1.22; p=0.005) and the presence of varicose veins in the lower limbs (OR 7.47; 95% CI 1.53-36.41; p=0.013) were predictors of CTEPH. PASP >60 mmHg at admission identified patients with CTEPH at follow-up with sensitivity and specificity of 83.3% and 76.3%, respectively. All patients diagnosed with CTEPH had at least two radiological findings suggestive of CTEPH at the index event. CONCLUSIONS: In our cohort, the prevalence of CTEPH in survivors of severe forms of acute PE was 6.2%. PASP above 60 mmHg and supporting radiological findings on the index computed tomography scan are highly suggestive of acute-on-chronic CTEPH.

Effects of the COVID-19 pandemic on health surveillance work. / Efeitos da pandemia de COVID-19 no trabalho em vigilância sanitária.

The COVID-19 pandemic has challenged managers and exposed weaknesses in health systems. In Brazil, the pandemic emerged amid difficulties to work in the Brazilian Unified Health System (SUS) and in health surveillance (HS). The purpose of this article is to analyze the effects of COVID-19 on the organization, working conditions, management, and performance of HS, according to the perception of capital city managers from three regions of Brazil. This is an exploratory, descriptive research with qualitative analysis. The Iramuteq software was used in the treatment of the textual corpus and analysis of descending hierarchical classification, which generated four classes: characteristics of HS work during the pandemic (39.9%), HS organization and working conditions during the pandemic (12.3%), effects of the pandemic on work (34.4%), and the class of the health protection of workers and the population (13.4%). HS implemented remote work, expanded work shifts, and diversified its actions. However, it faced difficulties with personnel, infrastructure, and insufficient training. The present study also pointed out the potential for joint actions concerning HS.

Management of hemotherapy services in the context of the COVID-19 pandemic. / Gestão dos serviços hemoterápicos no contexto da pandemia de COVID-19.

This study aimed to analyze the management of hemotherapy services (HS) in the context of the COVID-19 pandemic from the perspective of municipal managers in different regions of Brazil. A qualitative approach with semi-structured interviews was applied to HS managers in the three Brazilian capitals, from different regions of Brazil, during the period between September 2021 and April 2022. The textual content of the interviews was submitted to lexicographic textual analysis using the free access software, Iramuteq. The managers' perceptions resulted from the descending hierarchical classification (DHC) analysis, which generated six classes: availability of resources for the development of work; installed capacity of services; strategies and challenges for attracting blood donors; risks and worker protection; measures for crisis management; and communication strategies for the adhesion of candidates for donation. The analysis highlighted several strategies used by the management, as well as pointed out limits and challenges for HS organization and management, exacerbated in the context of the pandemic.

Transcriptome analyses of the cortex and white matter of focal cortical dysplasia type II: Insights into pathophysiology and tissue characterization.

Introduction: Focal cortical dysplasia (FCD) is a common cause of pharmacoresistant epilepsy. According to the 2022 International League Against Epilepsy classification, FCD type II is characterized by dysmorphic neurons (IIa and IIb) and may be associated with balloon cells (IIb). We present a multicentric study to evaluate the transcriptomes of the gray and white matters of surgical FCD type II specimens. We aimed to contribute to pathophysiology and tissue characterization. Methods: We investigated FCD II (a and b) and control samples by performing RNA-sequencing followed by immunohistochemical validation employing digital analyses. Results: We found 342 and 399 transcripts differentially expressed in the gray matter of IIa and IIb lesions compared to controls, respectively. Cholesterol biosynthesis was among the main enriched cellular pathways in both IIa and IIb gray matter. Particularly, the genes HMGCS1, HMGCR, and SQLE were upregulated in both type II groups. We also found 12 differentially expressed genes when comparing transcriptomes of IIa and IIb lesions. Only 1 transcript (MTRNR2L12) was significantly upregulated in FCD IIa. The white matter in IIa and IIb lesions showed 2 and 24 transcripts differentially expressed, respectively, compared to controls. No enriched cellular pathways were detected. GPNMB, not previously described in FCD samples, was upregulated in IIb compared to IIa and control groups. Upregulations of cholesterol biosynthesis enzymes and GPNMB genes in FCD groups were immunohistochemically validated. Such enzymes were mainly detected in both dysmorphic and normal neurons, whereas GPNMB was observed only in balloon cells. Discussion: Overall, our study contributed to identifying cortical enrichment of cholesterol biosynthesis in FCD type II, which may correspond to a neuroprotective response to seizures. Moreover, specific analyses in either the gray or the white matter revealed upregulations of MTRNR2L12 and GPNMB, which might be potential neuropathological biomarkers of a cortex chronically exposed to seizures and of balloon cells, respectively.

Grateful Workers, Satisfied Workers? A Portuguese Study about Organizational Happiness during COVID-19 Quarantine.

Although work satisfaction has been largely studied, gratitude is an emerging field within multiple sciences, including positive psychology, organizational behavior, and human resources marketing. This ex post facto study aims to characterize gratitude and understand its relations to job satisfaction in a non-probabilistic sample of 521 Portuguese workers (62.2% women), 30.90% and 69.10% in the public and private sector, respectively, mean ages of M = 43, SD = 12.6. Data were collected using anonymous questionnaires during the COVID-19 lockdown. Statistical analyses were performed in SPSS 26, and include Student's t-test, one-way ANOVA, Pearson's correlations, and a hierarchical linear regression model. Results confirm that Portuguese workers are grateful and satisfied at work. There were statistically significant differences between groups in sociodemographic (p < 0.001 and p < 0.05), professional (p < 0.01 and p < 0.001), and perceived living conditions variables (p < 0.05) regarding gratitude. Gratitude, alone, explains 8% of job satisfaction. According to the regression model (32.4%), perceptions of satisfaction initiatives and greater job security are also associated with higher levels of job satisfaction (23.6%). Implementation of gratitude-promoting strategies may increase job satisfaction, especially in the post-pandemic period. The investment in workers' organizational happiness, after the impacts of COVID-19 on work dynamics, is a differentiating organizations success dimension.

Detection of early-stage lung cancer in sputum using automated flow cytometry and machine learning.

BACKGROUND: Low-dose spiral computed tomography (LDCT) may not lead to a clear treatment path when small to intermediate-sized lung nodules are identified. We have combined flow cytometry and machine learning to develop a sputum-based test (CyPath Lung) that can assist physicians in decision-making in such cases. METHODS: Single cell suspensions prepared from induced sputum samples collected over three consecutive days were labeled with a viability dye to exclude dead cells, antibodies to distinguish cell types, and a porphyrin to label cancer-associated cells. The labeled cell suspension was run on a flow cytometer and the data collected. An analysis pipeline combining automated flow cytometry data processing with machine learning was developed to distinguish cancer from non-cancer samples from 150 patients at high risk of whom 28 had lung cancer. Flow data and patient features were evaluated to identify predictors of lung cancer. Random training and test sets were chosen to evaluate predictive variables iteratively until a robust model was identified. The final model was tested on a second, independent group of 32 samples, including six samples from patients diagnosed with lung cancer. RESULTS: Automated analysis combined with machine learning resulted in a predictive model that achieved an area under the ROC curve (AUC) of 0.89 (95% CI 0.83-0.89). The sensitivity and specificity were 82% and 88%, respectively, and the negative and positive predictive values 96% and 61%, respectively. Importantly, the test was 92% sensitive and 87% specific in cases when nodules were < 20 mm (AUC of 0.94; 95% CI 0.89-0.99). Testing of the model on an independent second set of samples showed an AUC of 0.85 (95% CI 0.71-0.98) with an 83% sensitivity, 77% specificity, 95% negative predictive value and 45% positive predictive value. The model is robust to differences in sample processing and disease state. CONCLUSION: CyPath Lung correctly classifies samples as cancer or non-cancer with high accuracy, including from participants at different disease stages and with nodules < 20 mm in diameter. This test is intended for use after lung cancer screening to improve early-stage lung cancer diagnosis. Trial registration ClinicalTrials.gov ID: NCT03457415; March 7, 2018.

Lazer, política e sociedade: as contribuições da SEJEL para os feirantes do Ver-o-Peso / Leisure, politics and society: the contributions of the fairground SEJEL for O-Ver-Weight

O presente estudo objetiva analisar as contribuições políticas das práticas sociais do lazer promovidas pela Secretaria Municipal de Esporte, Juventude e Lazer (SEJEL) para os feirantes do Ver-o-Peso (2018 a 2019) privilegiando o lazer no cotidiano dos feirantes enquanto direito social. Questões norteadoras: Existe alguma contribuição política pela SEJEL que garanta o Lazer enquanto direito Social em prol dos feirantes do Ver-o-Peso. Se existe? Como existe? Problema ­Como contribuir para as políticas da SEJEL que garanta o Lazer enquanto direito social, em prol dos feirantes do Ver-o-Peso? Metodologia: pesquisa documental qualitativa, enfoque materialismo dialético, método dialético, coleta de dados: jornal, vídeo, blog da SEJEL, leis, projeto de lazer da prefeitura para os feirantes. Resultado: as políticas da SEJEL estão enquadradas com um significado recreativo, havendo necessidade da efetivação de políticas públicas de lazer consolidadas com os feirantes para a compreensão enquanto direito social, e, também por parte dos governantes quando o mesmo está sendo vivido e entendido pelas vias do senso comum somente como descanso, entretenimento e mercadoria. A promoção social do lazer pode estar atrelada a um serviço muitas vezes de forma limitada e alienante de convívio social.

Objective: to analyze the contributions of the social practices of leisure promoted by the municipal Sport, Youth andSport (SEJEL) to the vendors of the Ver-o-Peso (2018 to 2019) for the quality and style of life of them, as well as for that leisure becomes privileged in everyday merchants and practice as a social right of citizenship under the foundations of public policies of leisure. Methodology: qualitative desk research, focus dialectical materialism, dialectical method, data collection, newspaper, video, blog SEJEL, laws, leisure project of city hall to the fairground. Result: The public policies of social practices of leisure SEJEL (2008 to 2012) is framed with a recreational significance, requiring the execution of public policy leisure consolidated with the vendors to understand as a social right, and also by the rulers when it is lived and understood by way of common sense only as entertainment and merchandise. The social promotion of leisure can be linked to a service often quite limited and alienating.

Fatores sociodemográficos associados ao uso do preservativo na população ribeirinha / Factores sociodemográficos asociados al uso del preservativo en una población ribereña / Sociodemographic factors associated with condom use in a riverside population

Objetivo: estimar a prevalência e fatores associados ao uso do preservativo em população ribeirinha. Materiais e método: estudo transversal, analítico, realizado com 209 ribeirinhos do estado da Paraíba, Brasil, de junho a outubro de 2019. Os dados foram coletados por meio de entrevista individual e privativa com a utilização de um questionário estruturado com variáveis sociodemográficas e de comportamento sexual. As análises foram realizadas pela regressão de Poisson e estimadas as razões de prevalência. Análises bivariadas e múltiplas foram utilizadas para identificar associação entre as variáveis sociodemográficas e comportamentais com o uso do preservativo. Resultados: a prevalência estimada de uso do preservativo foi de 18,2% (IC: 95% 13,0-23,4). Ribeirinhos com idade maior que 40 anos apresentaram menor probabilidade de uso do preservativo (RP = 0,53; IC: 95% 0,34-0,83). Por sua vez, ribeirinhos com mais de oito anos de estudo apresentaram maior probabilidade de uso do preservativo (RP = 3,94; IC 95% 2,65-5,88).Conclusões: a prevalência do uso do preservativo entre os ribeirinhos foi baixa. Entretanto, indivíduos com maior escolaridade apresentaram maiores chances de uso. A prevenção combinada é uma alternativa para o controle das infecções transmissíveis, sendo o preservativo a principal medida de prevenção; portanto, compreender as singu-laridades da população ribeirinha e os fatores de risco para a boa adesão é imprescindível

Objetivo: estimar la prevalencia y los factores asociados al uso del preservativo en una población ribereña. Materiales y método: estudio transversal analítico, realizado con 209 habitantes ribereños del estado de Paraíba, Brasil, entre junio y octubre de 2019. Los datos fueron recolectados a través de entrevistas individuales y privadas mediante un cuestionario estructurado con variables socio-demográficas y de comportamiento sexual. Los análisis se realizaron utilizando la regresión de Poisson, estimando las razones de prevalencia. Se utilizaron análisis bivariados y múltiples para identificar la asociación entre las variables sociodemográficas y conductuales relacionadas con el uso del preservativo. Resultados: la prevalencia estimada del uso de preservativo fue de 18,2 % (IC = 95 % 13,0-23,4). Los habitantes ribereños mayores de 40 años reportaron una menor probabilidad de uso del condón (RP = 0,53; IC del 95 %: 0,34-0,83). Por otro lado, los individuos con más de 8 años de escolaridad fueron más propensos a utilizar preservativo (RP = 3,94; IC 95 %: 2,65-5,88). Conclusiones: la prevalencia del uso del preservativo entre la población estudiada fue baja. Sin embargo, aquellos individuos con mayor grado de escolaridad fueron más propensos a emplearlo. La prevención combinada es una alternativa para el control de las infecciones transmisibles, siendo el preservativo la principal medida preventiva. Por lo tanto, resulta fundamental conocer las singularidades de la población ribereña y los factores de riesgo para una buena adherencia.

Objective: To estimate the prevalence and factors associated with condom use in a riverside population. Materials and method: Cross-sectional and analytical study with 209 riverside inhabitants in the state of Paraíba, Brazil, from June to October 2019. Data were collected through individual and private interviews using a structured questionnaire with sociodemographic and sexual behavior-related variables. Analysis was conducted using Poisson regression. Prevalence ratios were estimated. Bivariate and multiple analyzes were used to identify the association between sociodemographic and behavioral variables with condom use. Results: The estimated prevalence of condom use was 18.2% (95% CI: 13.0-23.4). Riverside people over 40 years were less likely to use condoms (PR = 0.53; 95% ci: 0.34-0.83). On the other hand, individuals with more than 8 years of schooling were more likely to use condoms (PR = 3.94; 95% CI: 2.65-5.88). Conclusions: The prevalence of condom use among participants was low. However, individuals with higher education attainment were more likely to use it. Combined prevention is an alternative to control communicable infections, with condoms being the main prevention measure. Consequently, understanding the singularities of similar populations and the risk factors for good adherence to condom use is essential.

Medidas de prevenção de lesão por pressão em enfermarias pediátricas: atuação dos profissionais de enfermagem / Pressure injury prevention measures in pediatric wards: nursing professionals' actions

RESUMO Objetivo classificar a qualidade da assistência de enfermagem e analisar a associação entre as caraterísticas dos profissionais e a execução de medidas preventivas de lesão por pressão em crianças hospitalizadas. Métodos estudo observacional, transversal, realizado com 235 profissionais de enfermagem. O instrumento de Prevenção de Lesão por Pressão possui três domínios, com 23 itens: Medidas preventivas e detecção precoce de lesão por pressão (9); Medidas de alívio de pressão (8) e Avaliação e notificação (6), analisados pelo Índice de Positividade para Qualidade da Assistência. Resultados predominou sexo feminino (98,7%), com idade média de 38,83 ± 9,94 anos, técnicos de enfermagem (57,4%) e com tempo de experiência profissional superior a cinco anos (77,1%). Constatou-se assistência predominantemente sofrível nos três domínios, em 82,6% das ações. Encontrou-se associação significante com as variáveis "participação em cursos" e "desgaste no trabalho" e uma tendência mais frequente de realização das medidas na faixa etária 31-40 anos. Conclusão a assistência de enfermagem foi predominantemente sofrível; a assistência associou-se à participação em cursos de aperfeiçoamento e desgaste no trabalho. Contribuições para a prática evidenciou-se a necessidade do investimento em capacitação profissional e oferta de insumos considerados indispensáveis para viabilizar uma assistência qualificada e segura.

ABSTRACT Objective to classify the quality of nursing care and analyze the association between professionals' characteristics and the implementation of preventive measures for pressure injuries in hospitalized children. Methods this observational, cross-sectional study involved 235 nursing professionals. The Pressure Injury Prevention instrument comprised three domains with a total of 23 items: Preventive measures and early detection of pressure injuries (9 items), Pressure relief measures (8 items), and Assessment and reporting (6 items), analyzed using the Positivity Index for Quality of Care. Results Most participants were females (98.7%), with a mean age of 38.83 ± 9.94 years, nursing technicians (57.4%), and had more than five years of experience (77.1%). Nursing care was predominantly inadequate across all three domains, with 82.6% of actions rated as poor. Significant associations were found between "participation in training courses" and "work-related exhaustion". There was a trend towards increased compliance with measurements among professionals aged 31-40. Conclusion nursing care was predominantly poor and participation in training courses and the presence of exhaustion were associated with better adherence to preventive measures. Contributions to practice the study highlights the pressing need for investments in professional training and the provision of necessary resources to support high-quality and safe nursing care.

Vigilância Sanitária em Debate: 10 anos de contribuição ao conhecimento em saúde / Health Surveillance in Debate: 10 years of contributions to knowledge in healthcare

Este debate, resultado de um breve estudo sobre o periódico Vigilância Sanitária em Debate: Sociedade, Ciência & Tecnologia (Visa em Debate) em sua primeira década, teve como objetivo apresentar uma visão panorâmica das publicações, que foram classificadas em categorias previamente definidas; também foram identificadas as instituições às quais os autores das publicações estavam vinculados. A categoria Objetos sob Controle Sanitário abriga o maior quantitativo de publicações, com 72,0% do total, entre as quais predominam alimentos, medicamentos, e serviços de saúde e de interesse da saúde. As categorias Sistema Nacional de Vigilância Sanitária; Regulação e Vigilância Sanitária; Doenças, Agentes, Epidemiologia; e Tecnologias Analíticas apresentam quantitativos semelhantes, em torno de 7,0%. Entre as instituições de vínculos dos autores, as universidades e outras instituições de ensino superior são aquelas com maior número de vínculos, em todas as regiões. A Região Sudeste concentra o maior número de referências, seguida do Nordeste, Sul, Centro-Oeste e, por último, a Região Norte. Também foram referidos vínculos a universidades de outros países, como Canadá, França, Portugal e Colômbia. Observou-se uma grande diversidade de temáticas em todas as categorias de classificação das publicações, também lacunas e/ou poucos trabalhos em certos temas relevantes para a área. Este estudo denota que o periódico vem se constituindo um relevante veículo de disseminação do conhecimento em saúde em geral e vigilância sanitária em especial. Neste pouco tempo já foi indexada em importantes bases de dados científicos e conta com uma boa classificação Qualis/Capes na área interdisciplinar da saúde, o que contribui para um número crescente de publicações oriundas de renomadas universidades.

This debate is the result of a brief study in the journal Health Surveillance in Debate: Society, Science & Technology (Visa em Debate) in its first decade. The objective is to present a panoramic view of the publications of this journal. The articles were classified into previously defined categories and the institutions to which the authors of the publications were linked were also identified. The category "Objects Under Sanitary Control" contains the largest number of publications, with 72.0% of the total, among which food, medicines and health services predominated. The categories "National Health Surveillance System", "Health Regulation and Surveillance", "Diseases, Agents, Epidemiology", and "Analytical Technologies" presented similar amounts of around 7.0%. Among the authors' affiliation institutions, universities and other higher education institutions are the ones with the highest number, in all regions. The Southeast region possesses the largest number of references, followed by the Northeast, South, Midwest, and finally the North region. In addition, links to universities in other countries, such as Canada, France, Portugal, and Colombia, were mentioned. A great diversity of themes was observed in all categories of classification and there are still gaps and/or few works in certain themes that are relevant to the area. This study shows that the journal has become a relevant vehicle for the dissemination of knowledge in health in general, and sanitary surveillance, in particular. In this short time, this journal has already been indexed in relevant scientific databases and has a good Qualis/Capes classification in the interdisciplinary area of health, which contributes to a growing number of publications from renowned universities.

Sputum analysis by flow cytometry; an effective platform to analyze the lung environment.

Low dose computed tomography (LDCT) is the standard of care for lung cancer screening in the United States (US). LDCT has a sensitivity of 93.8% but its specificity of 73.4% leads to potentially harmful follow-up procedures in patients without lung cancer. Thus, there is a need for additional assays with high accuracy that can be used as an adjunct to LDCT to diagnose lung cancer. Sputum is a biological fluid that can be obtained non-invasively and can be dissociated to release its cellular contents, providing a snapshot of the lung environment. We obtained sputum from current and former smokers with a 30+ pack-year smoking history and who were either confirmed to have lung cancer or at high risk of developing the disease. Dissociated sputum cells were counted, viability determined, and labeled with a panel of markers to separate leukocytes from non-leukocytes. After excluding debris and dead cells, including squamous epithelial cells, we identified reproducible population signatures and confirmed the samples' lung origin. In addition to leukocyte and epithelial-specific fluorescent antibodies, we used the highly fluorescent meso-tetra(4-carboxyphenyl) porphyrin (TCPP), known to preferentially stain cancer (associated) cells. We looked for differences in cell characteristics, population size and fluorescence intensity that could be useful in distinguishing cancer samples from high-risk samples. We present our data demonstrating the feasibility of a flow cytometry platform to analyze sputum in a high-throughput and standardized matter for the diagnosis of lung cancer.
