ABSTRACT

Resumo Introdução: A profissão policial é considerada de alto risco e exige um vigor físico e mental do trabalhador diante do serviço realizado. De tal modo que uma boa qualidade do sono é importante, pois impacta diretamente em diversos aspectos na saúde desses trabalhadores. Ademais, a falta de uma boa qualidade do sono devido ao trabalho pode influenciar negativamente a qualidade de vida no trabalho. Objetivo: Analisar a influência da qualidade do sono na qualidade de vida no trabalho de policiais militares. Metodologia: Estudo quantitativo, correlacionalde corte transversal, realizado no primeiro semestre de 2019, com policiais de três municípios da Bahia, Brasil. Foram utilizados três instrumentos: sociodemográfico e características laborais; qualidade de vida de vida no trabalho; e qualidade do sono. Foi aplicado o teste do qui quadrado para as variáveis sociodemograficas e ocupacionais. Posteriormente, foi aplicado o teste de correlação de Spearman entre a qualidade do sono com as dimensões da qualidade de vida no trabalho. Resultados: Evidenciou-se entre os 298 policiais que a mediana da idade foi de 40 anos e tempo de serviço ≤ 7 anos, observou-se também que os policiais com pior qualidade do sono apresentaram qualidade de vida no trabalho insatisfatória em todas as dimensões (biológica/fisiológica; psicológica/comportamental; sociológica/relacional; econômica/política, ambiental/organizacional). Conclusão: Os policiais sofrem com a qualidade do sono e consequentemente influencia negativamente a qualidade de vida no trabalho. Assim, há uma necessidade de desenvolver ações no ambiente de trabalho que possam diminuir os afastamentos decorrentes dos problemas de saúde ocasionados pela qualidade do sono.


Resumen Introdución: La formación policial se considera de alto riesgo y requiere vigor físico y mental por parte de la persona trabajadora antes de realizar el servicio. Para esto, la buena calidad de sueño es importante, ya que impacta directamente en la salud de la población trabajadora en varios aspectos. Además, la falta de una buena calidad de sueño debido al trabajo puede influir negativamente en la calidad de vida fuera del trabajo. Objetivo: Analizar la influencia de la calidad del sueño en la calidad de vida en el trabajo de policías militares. Metodología: Estudio cuantitativo, correlacional transversal, realizado en el primer semestre de 2019, con policías de tres municipios de Bahía, Brasil. Se utilizaron tres instrumentos: características sociodemográficas y laborales, calidad de vida en el trabajo y calidad de sueño. Se aplicó la prueba chi cuadrado para las variables sociodemográficas y ocupacionales. Posteriormente, se aplicó la prueba de correlación de Spearman entre la calidad del sueño y las dimensiones de calidad de vida en el trabajo. Resultados: La muestra fue de 298 policías, la mediana de edad fue de 40 años y la antigüedad en el servicio fue ≤ 7 años. También, se observó quienes tuvieron peor calidad de sueño, también tuvieron una calidad de vida en el trabajo insatisfactoria en todos sus dimensiones (biológica/fisiológica; psicológica/conductual; sociológica/relacional; económica/política, ambiental/organizacional). Conclusión: Quienes son agentes de policía sufren de mala calidad de sueño y, en consecuencia, se influye negativamente su calidad de vida en el trabajo. Por lo tanto, existe la necesidad de desarrollar acciones en el lugar de trabajo que pueda reducir los riesgos de problemas de salud causados por la calidad del sueño.


Abstract Background: Police training is considered high risk and demands physical and mental vigor from the worker before preforming the service. Therefore, sleep quality is important as it directly impacts the health of these workers in several aspects. Furthermore, the lack of sleep quality due to work can negatively influence the quality of life outside of work. Aim: To analyze the influence of sleep quality on the quality of life and work of military police officers. Methods: A quantitative, cross-sectional correlational study, conducted in the first half of 2019 with police officers from three municipalities in Bahia, Brazil. Three instruments were used: sociodemographic and work characteristics; quality of life at work; and sleep quality. The chi-square test was applied for sociodemographic and occupational variations. Subsequently, the Spearman correlation test was applied between sleep quality and the quality of life and work dimensions. Results: Among the 298 police officers the median age was 40 years and the length of service was ≤ 7 years. It was also observed that police officers with poorer sleep quality had an unsatisfactory quality of life at work in all its dimensions (biological/physiological; psychological/behavioral; sociological/relational; economic/political, environmental/organizational). Conclusion: Police officers suffer from poor sleep quality and this negatively influence their quality of life and work. Therefore, there is a need to develop actions in the workplace that may reduce the risks of health problems caused by poor sleep quality.

ABSTRACT

Background: Physiatrists are facing with survivors from disasters in both the acute and chronic phases of muscle and nerve injuries. Similar to many other clinical conditions, neuromusculoskeletal ultrasound can play a key role in the management of such cases (with various muscle/nerve injuries) as well. Accordingly, in this article, a recent single-center experience after the Turkey-Syria earthquake will be rendered. Methods: Ultrasound examinations were performed for various nerve/muscle lesions in 52 earthquake victims referred from different cities. Demographic features, type of injuries, and applied treatment procedures as well as detailed ultrasonographic findings are illustrated. Results: Of the 52 patients, 19 had incomplete peripheral nerve lesions of the brachial plexus (n=4), lumbosacral plexus (n=1), and upper and lower limbs (n=14). Conclusion: The ultrasonographic approach during disaster relief is paramount as regards subacute and chronic phases of rehabilitation. Considering technological advances (e.g., portable machines), the use of on-site ultrasound examination in the (very) early phases of disaster response also needs to be on the agenda of medical personnel.

ABSTRACT

PURPOSE: To evaluate the safety and effectiveness of percutaneous release procedures under sonography using Sono-Instruments® in the treatment of carpal tunnel syndrome (CTS) and trigger finger (TF). METHODS: Prospective study involving 30 patients, divided into two groups (15 CTS, and 15 TF). The primary outcomes were surgical performance-related outcomes (visibility, ease of use, satisfaction, duration) using Sono-Instruments® and patient-related outcomes (pain, activity limitations, time to return to work, functional scores). Secondary outcomes included complications. Patients were followed for two months post-operatively. RESULTS: In the CTS group, the average age of the patients was 58.7 years. The percutaneous release of the transverse carpal ligament was effectively completed in all cases, with excellent device performance and no adverse events. At one week, all patients could wash their hands, 80% could perform activities of daily living, and 80% of those working had returned to their activities. At two months, all patients had resumed all activities. Pillar pain was still present in 53.3%. In the TF group, the patients had an average age of 57.9 years. The percutaneous release of the A1 annular pulley was successful in all cases, with excellent device performance and no adverse events. At one week, all patients could wash their hands, 93.3% could do all activities of daily living, and 75% of those working were back to their professional activities. At two months, all patients were back to all activities of daily living and work. The DASH score was significantly improved at two months, compared to preoperative, for both groups (p < 0.001). CONCLUSION: Percutaneous sono-guided release using Sono-Instruments® is safe and efficient, and associated with quick functional recovery. LEVEL OF EVIDENCE: II.

ABSTRACT

Contextualização: A melatonina é um hormônio endógeno encontrado em quase todos os organismos e participa de vários processos fisiológicos. A suplementação de melatonina tem sido preconizada na mídia para o tratamento e prevenção de várias doenças. Entretanto, há carência de informações científicas disponíveis sobre seu real benefício para a saúde. Objetivos: Sumarizar as evidências de revisões sistemáticas da Cochrane, referentes à efetividade das intervenções com suplementação de melatonina em humanos. Métodos: Trata-se de overview de revisões sistemáticas Cochrane. Procedeu-se à busca na Cochrane Library (2023), sendo utilizado o descritor "MELATONIN". Todas as revisões sistemáticas de ensaios clínicos foram incluídas. O desfecho primário de análise foi a melhora clínica, a redução dos sintomas ou a prevenção da doença. Resultados: Oito estudos foram incluídos, totalizando 53 ensaios clínicos e 4.024 participantes. Houve evidência de efetividade apenas para controle de ansiedade em pacientes em pré-operatório (evidência moderada) em comparação com placebo e para prevenção e tratamento de jet lag de fuso horário (evidência alta de certeza). Discussão: Embora seja muito veiculada na mídia, a suplementação de melatonina carece de estudos de qualidade para análise de sua efetividade. Os estudos clínicos disponíveis até o momento são heterogêneos e apresentam limitações metodológicas. Poucas análises convergem com segurança para um bom nível de evidência que permita sua recomendação. Conclusão: Não há suporte com bom nível de evidência atualmente para a maioria das intervenções com suplementação de melatonina, sendo recomendada a realização de novos estudos prospectivos para melhor robustez dos achados e análises.

ABSTRACT

Sono-immunotherapy faces challenges from poor immunogenicity and low response rate due to complex biological barriers. Herein, we prepared MCTH nanocomposites (NCs) consisting of disulfide bonds (S-S) doped mesoporous organosilica (MONs), Cu-modified protoporphyrin (CuPpIX), mitochondria-targeting triphenylphosphine (TPP), and CD44-targeting hyaluronic acid (HA). MCTH NCs efficiently accumulate at the tumor site due to the overexpressed CD44 receptors on the membrane of the cancer cells. Under the function of HAase and glutathione (GSH), MCTH degrades and exposes TPP to deliver CuPpIX to the mitochondrial site and induce a reactive oxygen species (ROS) burst in situ under ultrasound irradiations, thereby causing severe mitochondria dysfunction. This cascade-targeting ability of MCTH NCs not only reinforces oxidative stress in cancer cells but also amplifies immunogenic cell death (ICD) to stimulate the body's immune response and alleviate the tumor immunosuppressive microenvironment. These NCs significantly enhance the infiltration of immune cells into the tumor, particularly CD8+ T cells, for a powerful antitumor sono-immunotherapy. The proposed cascade-targeting strategy holds promise for strengthening sono-immunotherapy for prostate cancer treatment and overcoming the limitations of traditional immunotherapy.

ABSTRACT

Sonodynamic therapy (SDT), a tumor treatment modality with high tissue penetration and low side effects, is able to selectively kill tumor cells by producing cytotoxic reactive oxygen species (ROS) with ultrasound-triggered sonosensitizers. N-type inorganic semiconductor TiO2 has low ROS quantum yields under ultrasound irradiation and inadequate anti-tumor activity. Herein, by using atomic layer deposition (ALD) to create a heterojunction between porous TiO2 and CoOx, the sonodynamic therapy efficiency of TiO2 can be improved. Compared to conventional techniques, the high controllability of ALD allows for the delicate loading of CoOx nanoparticles into TiO2 pores, resulting in the precise tuning of the interfaces and energy band structures and ultimately optimal SDT properties. In addition, CoOx exhibits a cascade of H2O2→O2→·O2 - in response to the tumor microenvironment, which not only mitigates hypoxia during the SDT process, but also contributes to the effect of chemodynamic therapy (CDT). Correspondingly, the synergistic CDT/SDT treatment is successful in inhibiting tumor growth. Thus, ALD provides new avenues for catalytic tumor therapy and other pharmaceutical applications.

ABSTRACT

INTRODUCTION: Obstructive sleep apnea (OSA) is one of the main risk factors for cardiovascular diseases and is associated with both morbidity and mortality. OSA has also been linked to arrhythmias and sudden death. OBJECTIVE: To assess whether OSA increases the risk of sudden death in the non-cardiac population. METHODS: This is a systematic review of the literature. The descriptors "sudden death" and "sleep apnea" and "tachyarrhythmias" and "sleep apnea" were searched in the PubMed/Medline and SciELO databases. RESULTS: Thirteen articles that addressed the relationship between OSA and the development of tachyarrhythmias and/or sudden death with prevalence data, electrocardiographic findings, and a relationship with other comorbidities were selected. The airway obstruction observed in OSA triggers several systemic repercussions, e.g., changes in intrathoracic pressure, intermittent hypoxia, activation of the sympathetic nervous system and chemoreceptors, and release of catecholamines. These mechanisms would be implicated in the appearance of arrhythmogenic factors, which could result in sudden death. CONCLUSION: There was a cause-effect relationship between OSA and cardiac arrhythmias. In view of the pathophysiology of OSA and its arrhythmogenic role, studies have shown a higher risk of sudden death in individuals who previously had heart disease. On the other hand, there is little evidence about the occurrence of sudden death in individuals with OSA and no heart disease, and OSA is not a risk factor for sudden death in this population.

ABSTRACT

Non-invasive external energy triggered efficient tumor therapy is a promising specific treatment strategy. Herein, a composite material of bismuth sodium titanate (BNT) and molybdenum disulfide (MoS2) with piezoelectric effect was designed for the synergistic treatment of breast cancer with near-infrared-II (NIR-II) light and ultrasound (US) activation. The BNT@MoS2 exhibit excellent photothermal and acoustic properties upon excitation by 1060 nm NIR-II laser and US, respectively. The synergistic effect of hyperthermia and reactive oxygen species (ROS) under photoacoustic action endows the BNT@MoS2 with remarkable anti-tumor activities, enabling them to eradicate breast cancer cells within 10 min. The work could provide new insights into the treatment of breast cancer.

ABSTRACT

This review discusses the possible methods for improving therapeutic efficacies of phthalocyanine (Pcs) -based therapeutic probes in photo- and sono-dynamic therapies under hypoxic conditions. Herein, the structural design strategies including varying the central metal, position substituents and the effects of adjuvant used in supplementing the therapeutics activities of Pcs or formation of NPs are discussed for cancer therapies in hypoxic conditions. Different mechanisms induced for cell death influenced by the compositions of the Pcs-probes are discussed. The focus mainly highlights the oxygen (O2) -dependent mechanisms including methods of supplementing tumour microenvironment O2-concentrations to promote PDT or SDT therapies. Alternatively, O2-independent mechanisms mainly used to evade hypoxia by stimulating anticancer processes that don't require O2 to initiate cell death, such as the Fenton reaction or thermal ablation effects.

ABSTRACT

Percutaneous release is a common treatment option for trigger finger stenosing tenosynovitis. While surgical and conservative treatments are available, percutaneous techniques offer several advantages, including faster recovery time, reduced complications, and simultaneous treatment of multiple trigger fingers. The sono-instrument is a minimally invasive device designed for surgical release of the A1 pulley in adults. The device is efficient and safe, and in addition, several design features enhance the visibility of the instrument under ultrasound imaging. The technique is truly percutaneous, as the whole operation is done through a single needle puncture. This minimizes postoperative discomfort and allows an immediate return to daily living and professional activities. The technique can be performed in an outpatient clinic under local anesthesia. The learning curve is quick; however, surgeons must acquire experience in hand sonography to master this new form of surgery. The aim of this article is to provide an in-depth exposition of the technical nuances, pearls, and pitfalls of this novel retrograde percutaneous release method. To our knowledge, this is the first retrograde truly percutaneous release technique yet described, facilitated by the novel Sono-Instruments®.

ABSTRACT

The extraction of cellulose using eco-friendly solvents has been gaining significant attention for a couple of decades. This study investigated the impact of benign and green solvents on the extraction, thermal stability, mechanical properties, and crystallinity of cellulose extracted from Urtica dioica (Stinging nettle) using a Sono-Microwave Assisted Chlorine free and Ionic Liquid (SMACIL) extraction technique. In this regard, the stalks were undergone through pre chemical treatment before starting bleaching them with hydrogen peroxide (HPO) and 1-butyl-3-methylimidazolium acetate (BMIM-Ac) having different mole ratios (5, 7.5, and 10) to expose cellulose. The Urtica dioica cellulose (UDC) was characterized using FTIR, tensile testing, FESEM, XRD, and TGA. The fibrillation and lumen can be seen in SEM images that confirm the extraction of cellulose. The results showed that the BMIM-Ac-10 gives the maximum cellulose yield (88 %) than other compositions. Moreover, the cellulose extracted using BMIM-Ac-10 has high mechanical strength which makes it a potential constituent for various applications in the field of materials science. These results have significant implications for the development of sustainable and efficient processes for the extraction of cellulose.

ABSTRACT

Dyes are one of the most common contaminants in industrial effluents, whose continuous release into the environment has become an increasing global concern. In this work, nanoparticles of zero-valent iron (NZVI) were synthesized using the chemical regeneration method ،and were utilized for the first time as a catalyst in the advanced Sono-Nano-Fenton hybrid method for the decomposition of Reactive Red 198 (RR198). The properties of zero-valent iron nanoparticles were analyzed using SEM and XRD. The effect of pH, initial dye concentration, nanoparticle dosage, zero-valent iron and H2O2 concentration on the decomposition efficiency of Red Reactive 198 was investigated. Comparing the efficiency of Reactivate 198 dye degradation in Sonolysis, Sono-NZVI, Sono-H2O2 and Sono-Nano Fenton processes showed that 97 % efficiency was achieved by the Sono-Nano Fenton process in 60 min. The kinetics of the removal process showed that this process follows pseudo-first-order kinetics and the Langmuir-Hinshelwood model. The results indicate that the effectiveness of the ultrasonic process in removing resistant organic pollutants such as dyes increases tremendously with the synergy of the Fenton process.

ABSTRACT

Generating electricity in hydrogel is very important but remains difficult. Hydrogel with electricity generation capability is more capable in bio-relevant tasks such as tissue engineering, artificial skin, or medical treatment, because electricity is indispensable in regulating physiological activities. Here, a porous and phase blending hydrogel structure for effective piezoionic electricity generation is developed. Dynamic electric field is generated taking advantage of the difference in streaming speeds of sodium and chloride in the material. Microscopic porosity and hydrophilic-hydrophobic phase blending are the two key factors for prominent piezoionic performance. Voltages as high as 600 mV are first realized in hydrogels in response to medical ultrasound stimulation. The hydrogel structure is also subjective to effective substance exchange and can actively enrich proteins from surroundings under mechanical stimuli. Preliminary applications in neural stimulation, constructing complex spatial-temporal chemical and electric field distribution patterns, mimetic tactile sensor, sample pretreatment in fast detection, and enzyme immobilization are demonstrated.

ABSTRACT

The ablation effect of focused ultrasound (FUS) has played an increasingly important role in the biomedical field over the past decades, and its non-invasive features have great advantages, especially for clinical diseases where surgical treatment is not available or appropriate. Recently, rapid advances in the adjustable morphology, enzyme-mimetic activity, and biostability of sono-activated materials have significantly promoted the medical application of FUS ablation. However, a systematic review of sono-activated materials based on FUS ablation is not yet available. This progress review focuses on the recent design, fundamental principles, and applications of sono-activated materials in the FUS ablation biomedical field. First, the different ablation mechanisms and the key factors affecting ablation are carefully determined. Then, the design of sono-activated materials with high FUS ablation efficiencies is comprehensively discussed. Subsequently, the representative biological applications are summarized in detail. Finally, the primary challenges and future perspectives are also outlined. We believe this timely review will provide key information and insights for further exploration of focused ultrasound ablation and new inspiration for designing future sono-activated materials. STATEMENT OF SIGNIFICANCE: The ablation effect of focused ultrasound (FUS) has played an increasingly important role in the biomedical field over the past decades. However, there are also some challenges of FUS ablation, such as skin burns, tumour recurrence after thermal ablation, and difficulty in controlling cavitation ablation. The rapid advance in adjustable morphology, enzyme-mimetic activity, and biostability of sono-activated materials has significantly promoted the medical application of FUS ablation. However, the systematic review of sono-activated materials based on FUS ablation is not yet available. This progress review focuses on the recent design, fundamental principles, and applications in the FUS ablation biomedical field of sono-activated materials. We believe this timely review will provide key information and insights for further exploration of FUS ablation.

ABSTRACT

Sono-photodynamic therapy is hindered by the limited tissue penetration depth of the external light source and the quick recombination of electron-hole owing to the random movement of charge carriers. In this study, orthorhombic ZnSnO3 quantum dots (QDs) with piezo-photoelectronic effects are successfully encapsulated in hexagonal upconversion nanoparticles (UCNPs) using a one-pot thermal decomposition method to form an all-in-one watermelon-like structured sono-photosensitizer (ZnSnO3 @UCNPs). The excited near-infrared light has high penetration depth, and the watermelon-like structure allows for full contact between the UCNPs and ZnSnO3 QDs, achieving ultrahigh Förster resonance energy transfer efficiency of up to 80.30%. Upon ultrasonic and near-infrared laser co-activation, the high temperature and pressure generated lead to the deformation of the UCNPs, thereby driving the deformation of all ZnSnO3 QDs inside the UCNPs, forming many small internal electric fields similar to isotropic electric domains. This piezoelectric effect not only increases the internal electric field intensity of the entire material but also prevents random movement and rapid recombination of charge carriers, thereby achieving satisfactory piezocatalytic performance. By combining the photodynamic effect arising from the energy transfer from UCNPs to ZnSnO3 , synergistic efficacy is realized. This study proposes a novel strategy for designing highly efficient sono-photosensitizers through structural design.

ABSTRACT

To treat a life-threatening disease like cancer, photodynamic therapy (PDT) and sonodynamic therapy (SDT) methods were combined into sono-photodynamic therapy (SPDT) as an effective therapeutic solution. Each day, the usage of phthalocyanine sensitizers increases in the therapeutic applications as they have the ability to produce more reactive oxygen species. In this context, a new diaxially silicon phthalocyanine sensitizer, containing triazole and tert-butyl groups, was synthesized. After elucidating the structure of the complex with elemental analysis, FT-IR, UV-Vis, MALDI-TOF MS and 1 H NMR, its photophysical, photochemical and sono-photochemical properties were examined. When singlet oxygen generation capacity of the new synthesized silicon phthalocyanine complex was determined and compared among photochemical (PDT; Ð¤Δ = 0.59 in DMSO, 0.44 in THF, 0.47 in toluene) and sonophotochemical (SPDT; Ð¤Δ = 0.88 in dimethyl sulfoxide (DMSO), 0.60 in tetrahydrofuran (THF), 0.65 in toluene) methods, it can be said that the complex is a successful sono-photosensitizer that can be used as a good SPDT agent in vitro or in vivo future studies.

ABSTRACT

ABSTRACT Objective: To investigate the single and combined associations between sleep disturbances (sleep duration, insomnia symptoms in the last 30 nights, and daytime tiredness) and performance in cognitive tests. Methods: Cross-sectional analysis of data from visit 2 (2012-2014) of the Longitudinal Study of Adult Health from a cohort of active and retired civil servants from six Brazilian capitals. Polynomial regression with quadratic term and multiple linear regression models were performed to assess single and combined associations between sleep disturbances and memory performance, fluency, executive functions, and global cognition. Results: A total of 7,248 participants were included, with a mean age of 62.7 years (standard deviation [SD]=5.9), and 55.2% were women. Inverted U-shaped associations were observed between sleep duration and performance on all cognitive abilities, suggesting that durations shorter or longer than seven hours are associated with worse performance, regardless of age. Reported insomnia was associated with worse executive function (β: -0.08; 95% confidence interval [CI]: -0.15 to -0.01), and the magnitudes of associations were higher for individuals with insomnia at two or more moments (β: -0.12; 95%CI -0.19 to -0.05) or, especially, insomnia combined with short sleep (β: -0.18; 95%CI -0.24 to -0.11). Insomnia in two or more periods was also associated with lower memory and global cognition. There was no association between any sleep disturbance tested and verbal fluency. Isolated daytime tiredness was not associated with performance in the evaluated tests. Conclusion: The results suggest that extreme sleep durations are detrimental to almost all cognitive abilities investigated, whereas insomnia appears to affect more severely the executive function.


RESUMO Objetivo: Investigar a associação isolada e combinada entre distúrbios do sono (duração do sono, sintomas de insônia nas últimas 30 noites e cansaço diurno) e desempenho em testes cognitivos. Métodos: Análise transversal dos dados da visita 2 (2012-2014) do Estudo Longitudinal de Saúde do Adulto de coorte de servidores públicos ativos e aposentados de seis capitais brasileiras. Regressão polinomial com termo quadrático e modelos de regressão linear múltipla foram realizados para avaliar associações isoladas e combinadas entre distúrbios do sono e desempenho na memória, fluência, funções executivas e cognição global. Resultados: Foram incluídos um total de 7.248 participantes, com média etária de 62,7 anos (desvio padrão [DP]=5,9), sendo 55,2% mulheres. Associações em forma de U invertido foram observadas entre duração do sono e desempenho em todas as habilidades cognitivas, sugerindo que durações menores ou maiores que sete horas estão associadas ao pior desempenho, independentemente da idade. O relato de insônia foi associado à pior função executiva (β: -0.08; IC95% -0.15 a -0.01), sendo as magnitudes das associações maiores para indivíduos com insônia em dois ou mais momentos (β: -0.12; intervalo de confiança [IC]95% -0.19 a -0.05) ou, especialmente, insônia combinada com sono curto (β: -0.18; IC95% -0.24 a -0.11). Insônia em dois ou mais períodos também foi associada à menor memória e cognição global. Não houve associação entre qualquer distúrbio do sono testado e fluência verbal. Cansaço diurno isolado não foi associado ao desempenho nos testes avaliados. Conclusão: Os resultados sugerem que a duração extrema do sono é prejudicial para quase todas as funções cognitivas investigadas, enquanto a insônia parece afetar mais fortemente a função executiva.
