RESUMO

Hebb postulated that, to store information in the brain, assemblies of excitatory neurons coding for a percept are bound together via associative long-term synaptic plasticity. In this view, it is unclear what role, if any, is carried out by inhibitory interneurons. Indeed, some have argued that inhibitory interneurons are not plastic. Yet numerous recent studies have demonstrated that, similar to excitatory neurons, inhibitory interneurons also undergo long-term plasticity. Here, we discuss the many diverse forms of long-term plasticity that are found at inputs to and outputs from several types of cortical inhibitory interneuron, including their plasticity of intrinsic excitability and their homeostatic plasticity. We explain key plasticity terminology, highlight key interneuron plasticity mechanisms, extract overarching principles and point out implications for healthy brain functionality as well as for neuropathology. We introduce the concept of the plasticitome - the synaptic plasticity counterpart to the genome or the connectome - as well as nomenclature and definitions for dealing with this rich diversity of plasticity. We argue that the great diversity of interneuron plasticity rules is best understood at the circuit level, for example as a way of elucidating how the credit-assignment problem is solved in deep biological neural networks.

RESUMO

BACKGROUND: A large-scale industrial fire occurred in Rouen, France, in 2019. This study assessed the health-related quality of life of people exposed to its consequences 1 year later. METHODS: The study population comprised inhabitants of the exposed area and a non-exposed area. A representative sample was randomly selected using a stratified design. Data were collected using a standardized questionnaire to describe fire exposure and to calculate three health-related quality of life scores according to the SF12-v2 scale. After adjustment, descriptive and multivariate analyses were conducted. RESULTS: The sample comprised 4773 participants (response rate 47.7%). In the exposed area, the average mental, physical and overall health scores were 47.5, 52.0 and 73.8 out of 100, respectively. Mean mental and overall health scores were higher in the non-exposed area (49.0 and 76.0, respectively). After adjustment, a lower mental health score was associated with a higher number of perceived types of exposure, reaching -3.72 points [-5.41; -2.04] for five or more different types of perceived exposure. A lower mental health score was associated with soot deposits (-1.04 [-1.70; -0.39]), perceiving odours [(-2.04 [-3.22; -0.86]) up to the day of data collection], and having seen, heard or been awakened by the fire (-1.21 [-1.90; -0.52]). A slightly lower physical health score was associated with soot deposits (-0.57 [-1.07; -0.08]). CONCLUSION: This study highlighted associations between exposure to the consequences of the industrial fire in Rouen and a deterioration of perceived health-related quality of life 1 year later, particularly the mental health dimension.

RESUMO

PURPOSE: To evaluate the parafoveal macular microvasculature and the macular function in patients with retinal vasculitis associated with Behçet's uveitis. METHODS: In 14 patients with inactive Behçet's uveitis and 26 control individuals (13 with nonocular Behçet's syndrome and 13 healthy subjects), we analyzed the retinal nerve fiber layer, ganglion cell layer, full retinal thickness, foveal avascular zone area and sectorial parafoveal vascular density in the superficial vascular plexus, intermediate capillary plexus, and deep capillary plexus using SPECTRALIS optical coherence tomography (OCT) 2 and OCT angiography. Macular sensitivity was analyzed using an MP-3 microperimeter. RESULTS: Eighteen eyes (78%) had a best-corrected visual acuity ≥ 20/25. Significant differences were found in Behçet's uveitis in comparison with the controls on the OCT and OCT angiography: 14.8%, 22.4%, and 14.9% ganglion cell layer thinning in the global, nasal, and inferior sectors, respectively; 6%, 13.2%, and 7.5% full retinal thickness thinning in the superior, nasal, and inferior sectors; and 16.8%, 14.9%, 23.6%, 15.8%, and 12.6% mean deep capillary plexus density reduction in the global, superior, nasal, inferior, and temporal sectors. Microperimetry data demonstrated significant mean reductions of 21% and 23.6% in central and average macular sensitivities and 28.8%, 40.4%, 27.7%, and 24.2% in the superior, nasal, inferior, and temporal sectors, respectively. Outer plexiform layer elevations were observed in Behçet's uveitis (69.6%). CONCLUSION: Behçet's uveitis presented structural and functional macular damage despite good best-corrected visual acuity, mainly affecting the nasal sector and the deep capillary plexus. On OCT and OCT angiography, quantitative and qualitative changes can be valuable biomarkers of ocular involvement in Behçet's syndrome.

RESUMO

To evaluate usability of and satisfaction with OrCam MyEye, a finger-size wearable assistive technology device for visually impaired during real-world tasks. This prospective multicenter study was conducted on visually impaired people recruited from 5 vision rehabilitation centers. Patients performed real-world tasks such as near and distance reading, money handling, colour identification and face recognition in 2 different scenarios: without using any low vision aid and with OrCam. System Usability Scale (SUS), Patient's Global Impression of Change (PGIC), the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0) and the Psychosocial Impact of Assistive Devices Scale (PIADS) were administered after the use of the OrCam device. Among the 100 participants, use of OrCam MyEye device improved many daily-living tasks (F = 1.67, P < .05), and in particular reading and face recognition. Multivariate logistic regression showed that age and visual field defect explained 89% of the variation in efficacy of the device. Nearly half (45%) of the participants indicated a positive rating with the SUS. The PGIC rates showed a minimal improvement with a mean score of 4.2 (SD:1.8). The most highlighted parameter with the QUEST 2.0 test was "ease of use" in 58% (48 subjects). The PIADS indicator showed that the device positively impacted on the daily-living tasks of users (r2 = 0.72, P < .05). Regression modelling demonstrated a good relation between the questionnaires scores and demographic, disease and visual factors (P < .05). OrCam MyEye allowed visually impaired people to read, handle money and face recognition independently. This device may offer to these subjects to be independent.

RESUMO

BACKGROUND: Lung cancer is the second most commonly occurring cancer. The ability to metastasize and spread to distant locations renders the tumor more aggressive. Members of the Rho subfamily of small GTP-binding proteins (GTPases) play a central role in the regulation of the actin cytoskeleton and in cancer cell migration and metastasis. In this study we investigated the role of the RhoA/Cdc42 GAP, StarD13, a previously described tumor suppressor, in malignancy, migration and invasion of the lung cancer cells A549. METHODS: We knocked down StarD13 expression in A549 lung cancer cells and tested the effect on cell migration and invadopodia formation using time lapse imaging and invasion assays. We also performed rescue experiments to determine the signaling pathways downstream of StarD13 and transfected the cells with FRET biosensors for RhoGTPases to identify the proteins involved in invadopodia formation. RESULTS: We observed a decrease in the level of expression of StarD13 in lung tumor tissues compared to normal lung tissues through immunohistochemistry. StarD13 also showed a lower expression in the lung adenocarcinoma cell line A549 compared to normal lung cells, WI38. In addition, the depletion of StarD13 increased cell proliferation and viability in WI38 and A549 cells, suggesting that StarD13 might potentially be a tumor suppressor in lung cancer. The depletion of StarD13, however, inhibited cell motility, conversely demonstrating a positive regulatory role in cell migration. This was potentially due to the constitutive activation of RhoA detected by pull down and FRET assays. Surprisingly, StarD13 suppressed cell invasion by inhibiting Cdc42-mediated invadopodia formation. Indeed, TKS4 staining and invadopodia assay revealed that StarD13 depletion increased Cdc42 activation as well as invadopodia formation and matrix degradation. Normal lung cells depleted of StarD13 also produced invadopodia, otherwise a unique hallmark of invasive cancer cells. Cdc42 knock down mimicked the effects of StarD13, while overexpression of a constitutively active Cdc42 mimicked the effects of its depletion. Finally, immunostaining and FRET analysis revealed the absence of StarD13 in invadopodia as compared to Cdc42, which was activated in invadopodia at the sites of matrix degradation. CONCLUSION: In conclusion, StarD13 plays distinct roles in lung cancer cell migration and invasion through its differential regulation of Rho GTPases. Video abstract.

RESUMO

PURPOSE: Colorectal cancer (CRC) is the third most common type of cancer worldwide, and it represents over half of all gastrointestinal cancer deaths. Knowing that cancer cells have a high proliferation rate, they require high amounts of amino acids, including arginine. In addition, several tumor types have been shown to downregulate ASS-1 expression, becoming auxotrophic for arginine. Therefore, Arginine deprivation is one of the promising therapeutic approaches to target cancer cells. This can be achieved through the use of a recombinant human arginase, HuArgI(Co)-PEG5000, an arginine degrading enzyme. METHODS: In this present study, the cytotoxic effect of HuArgI(Co)-PEG5000 on CRC cell lines (HT-29, Caco-2, Sw837) is examined though cytotoxicity assays. Wound healing assays, invasion assays, and adhesion assays were also performed to detect the effect on metastasis. RESULTS: Wound healing and invasion assays revealed a decrease in cell migration and invasion after treatment with arginase. Cells that were treated with arginase also showed a decrease in adhesion, which coincided with a decrease in RhoA activation, demonstrated though the use of a FRET biosensor to detect RhoA activation in a single cell assay, and a decrease in MMP-9 expression. Treating cells with both arginase and L-citrulline, which significantly restores intracellular arginine levels, reversed the effect of HuArgI(Co)-PEG5000 on cell viability, migration, and invasion. CONCLUSION: We can, therefore, conclude that colorectal cancer is partially auxotrophic to arginine and that arginine depletion is a potential selective inhibitory approach for motility and invasion in colon cancer cells.

RESUMO

OBJECTIVE: To analyze the satisfaction about the accessibility to the treatment of people with hypertension accompanied by the Family Health Strategy. METHOD: Cross-sectional study, conducted with 417 people living in a city in the state of Paraná, Brazil. The data collection was performed between February and June of 2016, using a satisfaction instrument regarding the services provided by the Primary Health Care, using issues related to treatment accessibility. A descriptive and inferential analysis to treat the variables was adopted. RESULTS: 417 people participated in the study, from which 62.4% were elderly, 67.8% were female and 55.2% were retired/pensioners. The economic accessibility was the best evaluated indicator. The regular evaluation of the services characteristic of the geographical and organizational accessibility was significantly associated to the inadequate monitoring of these users in the Family Health Strategy. CONCLUSION: The services offered to people with arterial hypertension were evaluated as regular, presenting the main barriers related to geographical and organizational aspects.

RESUMO

The study reported in this article aimed to analyse factors associated with the risk of ulceration in the feet of patients with diabetes using a conceptual hierarchic model. It was a cross-sectional study carried out with 1515 people with diabetes mellitus aged 40 years and older. The risk of foot ulceration was of higher significance in male patients with diabetes (adjusted odds ratio (OR)=1.39 (95% confidence interval (CI) 1.11 to 1.73); p=0.020), who did not practise a regular physical activity (adjusted OR=1.58 (95% CI 1.15 to 2.15); p=0.013), with time since diagnosis over 10 years (adjusted OR=1.42 (95% CI 1.10 to 1.86); p=0.011), who used insulin (adjusted OR=1.40 (95% CI 1.09 to 1.84); p=0.012), with retinopathy (adjusted OR=1.84 (95% CI 1.38 to 2.45); p=0.001) and who had had a previous stroke (adjusted OR=1.47 (95% CI 1.09 to 2.04); p=0.018). Mycosis on the nails and the interdigital spaces of the feet was statistically associated with ulceration risk independent of other variables of the model (adjusted OR=2.48 (95%CI 1.70 to 3.63); p=0.001). Finding the factors associated with ulceration contributes to the provision of quality care by nurses.

RESUMO

This study aimed to analyse the relationship between the organisational culture and feelings of pleasure and suffering among working nursing professionals. This was a cross-sectional correlational study conducted in a tertiary hospital with 214 nursing staff over 3 months using three instruments: professional characterisation, the Brazilian Instrument for Assessment of Organisational Culture, and the Scale of Pleasure and Suffering at Work. The analysis included descriptive statistics and the Spearman correlation test. The external integration practice was the domain most frequently found in the organisational culture and the feeling of pleasure-gratification predominated among the workers. Values of cooperative professionalism and wellbeing, and practices of external integration and relationship promotion, were related to increased pleasure and decreased suffering at work. These aspects depend on the organisational culture of the institution. Investigating organisational culture facilitates the understanding of potential collective coping strategies and the organisational changes that favour good mental health in nurses.

RESUMO

OBJECTIVE: Assess the quality of life of workers who underwent work adjustments and adaptations in a public state university. METHODS: This was a cross-sectional study carried out with 92 employees from a public state university. Data were collected from November 2012 to May 2013 using a population characterization questionnaire and the Medical Outcome Study 36-item Short Form, and then underwent a univariate and bivariate analysis through the Mann-Whitney test. RESULTS: The two domains that obtained the best scores were social function and emotional performance, whereas the ones with the worst scores were physical performance and body pain. Most workers did not note changes in their health status in the last year. CONCLUSIONS: The quality of life scores, in general, were not high, especially in physical aspects. Therefore, measures need to be implemented to evaluate the effectiveness of work adjustments and adaptations, in order to improve occupational health.

RESUMO

Objective To analyze the factors associated with the risk of ulceration in the feet of people with diabetes mellitus living in rural areas. Methods This is a cross-sectional study conducted with 293 individuals with diabetes mellitus, aged 40 years or older, living in the south of Brazil, in 2014. We analyzed socioeconomic variables, clinical conditions and foot self-care. We used the Poisson multiple regression model and the Prevalence Ratio (PR) and p-value<0.05 as a measure of association. Results 43.7% of the sample presented risk of foot ulceration. The highest prevalence of foot ulceration risk was associated with people with lower purchasing power (PRadjusted=1.62/IC95%:1.52-2.22), with retinopathy (PRadjusted=1.30/IC95%:1.12-1.68) and alteration in foot moisture (PRadjusted=1.57/IC95%:1.22-2.01). We identified low education level (64.2%), high prevalence of arterial hypertension (86.3%) and onychomycosis in the feet (72%). Conclusions Diabetic patients need an assessment of the risk of foot ulceration, especially those with longer diagnosis, chronic complications and low socio-educational level.

RESUMO

This study is the first faunistic inventory of hydromedusae from the inner continental shelf of Paraná State. We describe the composition of hydromedusae species, collected with bottom-trawl and Hensen nets, in campaigns carried out from 1997 to 2006. We analyzed 17,797 specimens from 578 samples, and provide descriptions, photographs, and information about the biology of the 22 species found. All species had previous records from the Brazilian coast; however, this is the first record of Bougainvillia frondosa, Ectopleura dumortieri, Cirrholovenia tetranema, Eucheilota maculata, Gossea brachymera, Solmaris corona, and Amphogona apsteini for the coast of Paraná. Most species are typical of tropical and subtropical coastal waters from the South Brazilian Bight. However, Turritopsis nutricula, Niobia dendrotentaculata, Solmaris corona, and Aglaura hemistoma are abundant in oceanic waters, and Olindias sambaquiensis and Solmaris corona are associated with colder waters (<20°C). The current number of species known for the state is 26. Additional collection effort is needed in regions not sampled in this work, such as bays and offshore waters.

RESUMO

Podocoryna loyola, a new hydractiniid species, has been found on artificial substrates in Baía de Paranaguá, southern coast of Brazil, since April 2007. Its main morphological characteristics are: (1) polymorphic colonies with reticular stolons or encrusting hydrorhiza not covered by periderm and smooth chitinous spines; (2) newly-released medusae with eight tentacles and small interradial gonads; (3) mature medusae with eight tentacles and unbranched oral lips; gastric peduncle absent. Molecular data show that P. loyola is distinct from all other examined species of Podocoryna, and from P. hayamaensis Hirohito (1988), its sister species from Japan. As the polyps having been noted only quite recently, and in having been found only on man-made objects in port areas and estuaries, the species is most likely exotic to the region.

RESUMO

OBJECTIVE: To analyze the direct cost of reusable and disposable aprons in a public teaching hospital. METHOD: Cross-sectional study of quantitative approach, focusing on the direct cost of reusable and disposable aprons at a teaching hospital in northern Paraná. The study population consisted of secondary data collected in reports of the cost of services, laundry, materials and supplies division of the institution for the year 2012. RESULTS: We identified a lower average cost of using disposable apron when compared to the reusable apron. The direct cost of reusable apron was R$ 3.06, and the steps of preparation and washing were mainly responsible for the high cost, and disposable apron cost was R$ 0.94. CONCLUSION: The results presented are important for hospital managers properly allocate resources and manage costs in hospitals

RESUMO

People tend to spend more time in front of their screens, which can have repercussions on their social life, physical and mental health. This topic has mainly been studied in adolescents. Therefore, our study tested associations between the use of video games, social media and online dating leading to sexual relations (ODLSR), and symptoms of anxiety and/or depression among adults aged 25 and over. Data from the 2018 TEMPO cohort study were analyzed (n = 853, 65.0% women, aged 25-44, with an average of 37.4 ± 3.7 years). The exposure variables were as follows: (a) the frequency of video game use, (b) time spent on social media and (c) ODLSR. Data were analyzed using multivariate logistic regression models, adjusted for participants' sociodemographic characteristics as well as history of mental health problems. Among the participants, 8.6% presented symptoms of anxiety and/or depression. An association between ODLSR and symptoms of anxiety and/or depression was found, especially among women. The results of this study will facilitate the improvement of support and care for adults, especially those with symptoms of anxiety and/or depression using dating applications. Future studies should investigate the determinants of using online meeting websites and their relationship with the occurrence of psychological difficulties in longitudinal studies to establish causality.

RESUMO

BACKGROUND: COVID-19 vaccine acceptance among refugees in the Arab region remains low. This study aimed to examine the prevalence, reasons and predictors of intention to refuse the COVID-19 vaccine among older Syrian refugees in Lebanon. METHODS: A nested cross-sectional study within a longitudinal study among older Syrian refugees in Lebanon. The sampling frame was a complete listing of beneficiary households of a humanitarian organization with at least one adult aged 50 years or older. Telephone surveys were completed at months 1 starting September 2020 (wave 1), months 2 (wave 2), months 5 (wave 3), months 6 (wave 4) and months 17 (wave 5) in March 2022. Logistic regression models were used to identify predictors of intention to refuse the COVID-19 vaccine. Models were internally validated using bootstrap methods and the models' calibration and discrimination were presented. FINDINGS: Of 3167 Syrian refugees, 61.3% intended to receive the COVID-19 vaccine, 31.3% refused, and 7.4% were undecided. Reasons for vaccine refusal were: preference to follow preventive measures (27.4%) and belief that the vaccine is not essential (20.7%). Furthermore, 57.1% of participants registered to take the COVID-19 vaccine in wave 5. Irrespective of vaccination intention, reasons for not registering included: not wanting to receive the vaccine, and being unsure whether to take it. Predictors of intention to refuse the COVID-19 vaccine included: being a female, older age, having elementary education or above, living outside informal tented settlements, perceiving COVID-19 as not severe and vaccines as not safe or effective, and using social media for information on COVID-19. After adjusting for optimization, the final model showed moderate discrimination (C-statistic: 0.651 (95% CI:0.630-0.672)) and good calibration (C-slope: 0.93 (95% CI: 0.823-1.065)). CONCLUSIONS: This study developed a predictive model for vaccination intention with a moderate discriminative ability and good calibration. Prediction models in humanitarian settings can help identify refugees at higher risk of not intending to receive the COVID-19 vaccine for public health targeting.

RESUMO

OBJECTIVE: to develop and validate the content and technical aspects of a web software program for promoting mental health in the workplace. METHOD: applied methodological study and technological development, carried out in three stages: 1) Umbrella review development; 2) Web software development; 3) Content and technical validation carried out by 14 judges. The data was submitted to descriptive statistical analysis and calculation of the content validity index. RESULTS: based on the guidelines' recommendations, information was defined and extracted in order to develop the web software consisting of the following dimensions: mental health education, support among coworkers, promotion strategies and mental health self-assessment. For the technical development, the objectives, general functions and technological infrastructure were defined. After development and functional testing, the version was made available for content and technical validation by judges. The overall content validity index was 0.98 and for the technical aspects it was 0.97. CONCLUSION: the agreement between the judges in relation to the content and technical aspects, as well as the suggestions incorporated, demonstrated the potential for using web software to promote mental health in the workplace.

RESUMO

BACKGROUND: Children's mental health, including their well-being, is a major public health concern, as the burden of related disorders may last throughout one's life. Although epidemiological mental health surveillance systems for children and adolescents have been implemented in several countries, they are sorely lacking in France. OBJECTIVE: This study aims to describe the first step of the implementation of a novel surveillance system in France called Enabee (Etude nationale sur le bien-être des enfants), which focuses on the issue of mental health in children. The system aims to (1) describe the temporal trends in the population-based prevalence of the main mental health disorders and well-being in children aged 3 to 11 years, (2) explore their major determinants, and (3) assess mental health care use by this population. To do this, Enabee will rely on results from a recurrent national cross-sectional homonymous study. This paper presents the protocol for the first edition of this study (called Enabee 2022), as well as initial results regarding participation. METHODS: Enabee 2022 is a national cross-sectional study that was implemented in French schools in 2022. It used a probabilistic, multistage, stratified, and balanced sampling plan as follows: first, schools were randomly drawn and stratified according to the type of school. Up to 4 classes per school were then randomly drawn, and finally, all the pupils within each class were selected. The study covered children from preschool and kindergarten (aged 3 to 6 years, US grading system) to fifth grade (aged 6 to 11 years). Children from first to fifth grades provided a self-assessment of their mental health using 2 validated self-administered questionnaires: the Dominic Interactive (DI) and the KINDL. Parents and teachers completed a web-based questionnaire, including the Strengths and Difficulties Questionnaire. Parents also answered additional questions about their parenting attitudes; their own mental health; known social, economic, and environmental determinants of mental health in children; and their child's life habits. Health, education, and family stakeholders were involved in designing and implementing the study as part of a large consultation group. RESULTS: Data were collected from May 2, 2022, to July 31, 2022, in 399 schools across metropolitan France. Teachers completed questionnaires for 5721 pupils in preschool and kindergarten and for 15,263 pupils from first to fifth grades. Parents completed questionnaires for 3785 children in preschool and kindergarten and for 9227 children from first to fifth grades. Finally, 15,206 children from first to fifth grades completed the self-administered questionnaire. CONCLUSIONS: Enabee 2022 constitutes the first milestone in the development of a novel national epidemiological surveillance system, paving the way for improved children's mental health policies in France.

RESUMO

OBJECTIVE: To verify the factors associated with the type of work activity performed by university technical-administrative staff retired due to disability. METHOD: Cross-sectional research with 68 workers, conducted using an electronic questionnaire between November 2019 and September 2020. Data were collected on sociodemographic, occupational characterization and causes of disability. Data were analyzed descriptively and by multiple logistic regressions. RESULTS: Health professionals were more likely to have mental and behavioral disorders, associated with females and regardless of age. The chances of the nervous system diseases were higher in workers who performed administrative work, being associated with higher education. Operational employees were more likely to have musculoskeletal diseases associated with primary and secondary education and were male, regardless of age. CONCLUSION: There was an association between work activity performed before retirement and the diseases responsible for disability, with differences between gender, age, and educational levels.

RESUMO

OBJECTIVES: to assess high-risk prenatal care and identify strategies for improving care. METHODS: a mixed study of a prospective cohort, with 319 mothers in a public maternity hospital, from October 2016 to August 2017, using a semi-structured instrument and interview. Analysis was performed using the chi-square test (p≤0.05). The qualitative approach was carried out through interviews with guiding questions to 13 managers, at their workplace, between January and March 2020, analyzed under social phenomenology. RESULTS: higher rates of inadequacy were identified for all criteria. However, when care was shared, there was a higher rate for performing tests (p=0.023), consultations (p=0.002), risk stratification (p=0.013) and emergency information (≤0.000). Weaknesses in the record evidenced impairment in communication and continuity of care. FINAL CONSIDERATIONS: shared care is a strategy for improving care, however there is a need to strengthen effective referral and counter-referral to care continuity.
