Is Iron Overload Associated with Worse Outcomes in Patients with Chronic Liver Disease Undergoing Liver Transplantation?

ABSTRACT Background: Iron overload is frequent in patients with chronic liver disease, associated with shorter survival after liver transplantation in patients with hereditary hemochromatosis. Its effect on patients without hereditary hemochromatosis is unclear. The aim of the study was to study the clinical impact of iron overload in patients who underwent liver transplantation at an academic tertiary referral center. Methods: We performed a retrospective cohort study including all patients without hereditary hemochromatosis who underwent liver transplantation from 2015 to 2017 at an academic tertiary referral center in Mexico City. Explant liver biopsies were reprocessed to obtain the histochemical hepatic iron index, considering a score ≥ 0.15 as iron overload. Baseline characteristics were compared between patients with and without iron overload. Survival was estimated using the Kaplan-Meier method, compared with the log-rank test and the Cox proportional hazards model. Results: Of 105 patients included, 45% had iron overload. Viral and metabolic etiologies, alcohol consumption, and obesity were more frequent in patients with iron overload than in those without iron overload (43% vs. 21%, 32% vs. 22%, p = 0.011; 34% vs. 9%, p = 0.001; and 32% vs. 12%, p = 0.013, respectively). Eight patients died within 90 days after liver transplantation (one with iron overload). Complication rate was higher in patients with iron overload versus those without iron overload (223 vs. 93 events/100 person-months; median time to any complication of 2 vs. 3 days, p = 0.043), without differences in complication type. Fatality rate was lower in patients with iron overload versus those without iron overload (0.7 vs. 4.5 deaths/100 person-months, p = 0.055). Conclusion: Detecting iron overload might identify patients at risk of early complications after liver transplantation. Further studies are required to understand the role of iron overload in survival.

Abstract Objectives to identify balance assessment instruments, issues and risks of issues used in COPD, evaluate their measurement properties, quality of evidence and clinical utility. Method A review was produced following the PRISMA and COSMIN guidelines, registered in PROSPERO: CRD42021235118. Searches were carried out from November 2021 to September 2022 in the PubMed, LILACS, CINAHL, Embase, Web of Science and PEDro databases. Cross-sectional and cohort observational studies were included, without restrictions on language or year of publication, as long as they described clinical instruments for assessing balance, falls and risk of falls reporting at least one of the measurement properties: validity, reliability and responsiveness. Two reviewers will independently apply the eligibility criteria, travel risk by COSMIN, quality of evidence by the GRADE approach and assessment of clinical utility by the Tyson and Connell Scale. Results 9,102 studies were selected and 21 included in the review, nine studies demonstrated adequate and sufficient measurement properties and 12 instruments were identified, of which six were evaluated for the quality of evidence. Conclusion Systematic reviews of measurement properties require specialized reviewers and skills in qualitative analysis. With a recommendation GRADE of "A", the Berg Balance Scale (BBS) and the Timed Up and Go (TUG) test were the most recommended instruments for COPD. By requiring the evaluation of the clinical utility of the result, the TUG demonstrates superiority to the BBS, proving to be a great tool for judging individuals who need a thorough assessment of balance, falls and risk of falls.

Multivariate guard-bands and total risk assessment on multiparameter evaluations with correlated and uncorrelated measured values

Abstract The quality, efficacy, and safety of medicines are usually verified by analytical results. Measurement uncertainty is a critical aspect for the reliability of these analytical results. The pharmacopeial compendia usually adopt a simple acceptance rule that does not consider information from measurement uncertainty. In this work, we compared decision-making using simple acceptance and decision rules with the use of guard-band for multiparameter evaluation of ofloxacin ophthalmic solution and acyclovir topical cream. Ciprofloxacin ophthalmic solution and acyclovir topical cream samples were subject to pharmacopeial tests and assays. Multivariate guard-band widths were calculated by multiplying the standard uncertainty (u) by an appropriate multivariate coverage factor (k'). The multivariate coverage factor (k') was obtained by the Monte Carlo method. According to the simple acceptance rule, all the results obtained for ciprofloxacin ophthalmic solution and acyclovir topical cream are within the specification limits. However, the risk of false conformity decisions increases for ciprofloxacin tests. Decisions made using the simple acceptance rule and decision rules with the use of guard-band may differ. The simple acceptance rule may increase the risk of false conformity decisions when the measured value is close to the regulatory specification limits and/or when the measurement uncertainty value is inappropriately high. Nevertheless, the guard-band decision rule will always reduce the risk of false conformity decisions. Therefore, using information on measurement uncertainty in conformity assessment is highly recommended to ensure the proper efficacy, safety, and quality of medicines.

Risk of false conformity decisions due to measurement uncertainty of Active Pharmaceutical Ingredient: A multiparametric evaluation

Abstract Medicines must be subject to physical, chemical, and biological analysis to guarantee their quality, safety, and effectiveness. Despite the efforts to ensure the reliability of analytical results, some uncertainty will always be associated with the measured value, which can lead to false decisions regarding conformity/non-conformity assessment. This work aims to calculate the specific risk of false decisions regarding conformity/non-conformity of acetaminophen oral solution dosage form. The acetaminophen samples from five different manufacturers (A, B, C, D, and E) were subject to an active pharmaceutical ingredient assay, density test, and dose per drop test according to the official compendia. Based on measured values and their respective uncertainties, the risk values were calculated using the Monte Carlo method implemented in an MS Excel spreadsheet. The results for two acetaminophen oral solution samples (C and D) provided an increased total risk value of false acceptance (33.1% and 9.6% for C and D, respectively). On the other hand, the results for the other three acetaminophen samples (A, B, and E) provided a negligible risk of false acceptance (0.004%, 0.025%, and 0.045% for A, B, and E, respectively). This indicates that measurement uncertainty is very relevant when a conformity assessment is carried out, and information on the risks of false decisions is essential to ensure proper decisions.

Medicines for managing lower pain in patients with failed back surgery syndrome treated with neuromodulation / Medicamentos para manejo da dor em pacientes com síndrome da falha da cirurgia na coluna tratados com neuromodulação / Medicamentos para el manejo del dolor en pacientes con síndrome de cirugía fallida de columna tratados con neuromodulación

ABSTRACT Objective: To compare the use of drugs to control low back pain in the pre- and postoperative periods among patients with Failed Back Surgery Syndrome (FBSS) undergoing neuromodulation. Methods: Retrospective observational study analyzing the medical records of patients with FBSS who underwent neuromodulation, followed up in an outpatient clinic from 2018 to 2020. The characteristics of the patients were evaluated: the use of medications, quality of life through the results of the Short Form 36 Health Survey Questionnaire (SF-36), and functional capacity using the Oswestry Disability Index (ODI) in the pre-surgical and post-surgical periods (06 months, 01 year). The criterion for establishing statistical significance was p≤0.05. Results: 56 patients were evaluated. There was a reduction in the use of pain control drugs after the institution of neuromodulation, including in the opioid class (d=0.81). An improvement was also observed in the ODI scores (p<0.001) and all the SF-36 domains (p<0.02) in the postoperative periods investigated. Conclusion: The data suggest that neuromodulation positively impacted back pain by reducing medication use and improving functional capacity and quality of life.

Naive skepticism scale: development and validation tests applied to the chilean population

Abstract Background Skepticism has traditionally been associated with critical thinking. However, philosophy has proposed a particular type of skepticism, termed naive skepticism, which may increase susceptibility to misinformation, especially when contrasting information from official sources. While some scales propose to measure skepticism, they are scarce and only measure specific topics; thus, new instruments are needed to assess this construct. Objective This study aimed to develop a scale to measure naive skepticism in the adult population. Method The study involved 446 individuals from the adult population. Subjects were randomly selected for either the pilot study (phase 2; n = 126) or the validity-testing study (phase 3; n = 320). Parallel analyses and exploratory structural equation modelling were conducted to assess the internal structure of the test. Scale reliability was estimated using Cronbach's alpha and McDonald's omega coefficients Finally, a multigroup confirmatory factor analysis was performed to assess invariance, and a Set- Exploratory Structural Equation Modeling was applied to estimate evidence of validity based on associations with other variables. Results The naive skepticism scale provided adequate levels of reliability (ω > 0.8), evidence of validity based on the internal structure of the test (CFI = 0.966; TLI = 0.951; RMSEA = 0.079), gender invariance, and a moderate inverse effect on attitudes towards COVID-19 vaccines. Conclusions The newly developed naive skepticism scale showed acceptable psychometric properties in an adult population, thus enabling the assessment of naive skepticism in similar demographics. This paper discusses the implications for the theoretical construct and possible limitations of the scale.

Measurement invariance of the satisfaction with leisure satisfaction scale by gender, marital status, and age

Abstract Background Leisure satisfaction is the degree of positive perception and emotions that an individual acquires as a result of participating in leisure time activities, and it has an important function in maintaining and increasing leisure time participation. Some studies on leisure satisfaction address the comparisons between groups. These studies are based on the premise that the measurement tool used to reveal the between-group differences measures the same feature in subgroups. Objective In this study, we investigated whether the differences between the groups were due to the measurement tool by examining the psychometric properties of the leisure satisfaction scale. Methods The study sample comprised 2344 exercising individuals, including 1228 (52.3%) women and 1116 (47.6%) men. The structural invariance of the leisure satisfaction scale, developed by Beard and Ragheb (Journal of Leisure Research 12:20-33, 1980) and adapted into Turkish by Gökçe and Orhan (Spor Bilimleri Dergisi 22:139-145, 2011), was tested through multiple-group confirmatory factor analysis. Results The results indicated that the structural and metric invariance conditions were fulfilled across gender, marital status, and age in all subscales of the leisure satisfaction scale. Scalar invariance was obtained in educational and social satisfaction subscales across gender and in physical satisfaction subscale across marital status. Conclusion The study provides evidence for the future comparisons according to these three variables, indicating that the differences obtained will result from the real differences between groups rather than the measurement tool properties.

Screening and prevention of preterm birth: how is it done in clinical practice?

Abstract Objective: To ascertain how screening for preterm birth is performed among obstetricians working in public and private practice in a middle-income country. Methods: Cross-sectional study of 265 obstetrician-gynecologists employed at public and private facilities. An online questionnaire was administered, with items designed to collect data on prematurity screening and prevention practices. Results: The mean age of respondents was 44.5 years; 78.5% were female, and 97.7% had completed a medical residency program. Universal screening (i.e., by ultrasound measurement of cervical length) was carried out by only 11.3% of respondents in public practice; 43% request transvaginal ultrasound if the manual exam is abnormal, and 74.6% request it in pregnant women with risk factors for preterm birth. Conversely, 60.7% of respondents in private practice performed universal screening. This difference in screening practices between public and private practice was highly significant (p < 0.001). Nearly all respondents (90.6%) reported prescribing vaginal progesterone for short cervix. Conclusion: In the setting of this study, universal ultrasound screening to prevent preterm birth was used by just over half of doctors in private practice. In public facilities, screening was even less common. Use of vaginal progesterone in cervical shortening was highly prevalent. There is an unmet need for formal protocols for screening and prevention of preterm birth in middle-income settings.

Resumo: O objetivo do estudo é analisar o perfil de egressos e identificar fatores associados ao desempenho positivo relativo à trajetória de formação e de inserção profissional entre aqueles que concluíram cursos presenciais de mestrado e doutorado acadêmico da Fundação Oswaldo Cruz (Brasil). Participaram do estudo 2.462 egressos (1.402 de mestrado e 1.060 de doutorado) que responderam um questionário digital, contendo questões sobre perfil do egresso e inserção profissional antes do ingresso no curso e após a conclusão. Foi criada uma medida sobre "desempenho positivo pós-curso". Os resultados revelam que egressos de mestrado com impacto positivo do curso tendem a ser homens; ter especialização antes de ingressar no curso; ter emprego remunerado após o término do curso nas áreas de pesquisa, educação, assistência e gestão; e ser servidor público. No doutorado o seguinte perfil é evidenciado: egressos com emprego remunerado após o término do curso nas áreas de pesquisa ou educação; contratados por Regime Jurídico Único ou contrato temporário de pessoa jurídica; e com publicação científica ou patente. A avaliação/acompanhamento de egressos deve se instaurar como uma importante política pública educacional, incorporada no processo de autoavaliação institucional, o que possibilita rever rumos e prioridades na agenda educacional e pedagógica da instituição.

Abstract: This study aims to analyze the profile of graduates and identify factors associated with positive performance regarding training and professional insertion among those who have completed face-to-face master's and doctoral courses at the Oswaldo Cruz Foundation (Brazil). A total of 2,462 graduates participated in the study (1,402 master's and 1,060 doctoral graduates), who answered a digital questionnaire containing questions about individual characteristics and professional insertion before entering the course and after completion. A measure on "positive post-course performance" was created. The results show that Master's graduates with a positive impact from the course tend to be men; to have a specialization degree before entering the course; to have paid employment after finishing the course in the areas of research, education, assistance, and management; and to be civil servants. In the Doctorate, the following profile is evident: graduates with paid employment after finishing the course in the areas of research or education; hired under a single legal regime or temporary contract as a legal entity; and with a scientific publication or patent. Evaluating/monitoring graduates must be established as an important public educational policy, incorporated into the institutional self-evaluation process, which makes it possible to review directions and priorities in the institution's educational and pedagogical agenda.

Pediatricians' focus of sight at pain assessment during a neonatal heel puncture / Foco do olhar do pediatra na avaliação da dor neonatal durante uma punção de calcanhar

ABSTRACT Objective: To evaluate the focus of pediatricians' gaze during the heel prick of neonates. Methods: Prospective study in which pediatricians wearing eye tracker glasses evaluated neonatal pain before/after a heel prtick. Pediatricians scored the pain they perceived in the neonate in a verbal analogue numerical scale (0=no pain; 10=maximum pain). The outcomes measured were number and time of visual fixations in upper face, lower face, and hands, in two 10-second periods, before (pre) and after the puncture (post). These outcomes were compared between the periods, and according to pediatricians' pain perception: absent/mild (score: 0-5) and moderate/intense (score: 6-10). Results: 24 pediatricians (31 years old, 92% female) evaluated 24 neonates. The median score attributed to neonatal pain during the heel prick was 7.0 (Interquartile range: 5-8). Compared to pre-, in the post-periods, more pediatricians fixed their gaze on the lower face (63 vs. 92%; p=0.036) and the number of visual fixations was greater on the lower face (2.0 vs. 5.0; p=0.018). There was no difference in the number and time of visual fixations according to the intensity of pain. Conclusions: At bedside, pediatricians change their focus of attention on the neonatal face after a painful procedure, focusing mainly on the lower part of the face.

RESUMO Objetivo: Avaliar o foco do olhar do pediatra durante a punção do calcanhar de neonatos. Métodos: Estudo prospectivo no qual pediatras, utilizando óculos de rastreamento visual, avaliaram a dor neonatal antes/depois de uma punção de calcanhar. Os pediatras pontuaram a dor de acordo com a sua percepção por meio de uma escala analógica verbal (0=sem dor; 10=dor máxima). Os desfechos analisados foram o número e o tempo das fixações visuais na face superior, face inferior e mãos, em dois períodos de 10 segundos, antes (PRÉ) e depois da punção (PÓS). Os resultados foram comparados entre os períodos e segundo a percepção da dor do pediatra: ausente/leve (escore: 0-5) e moderada/grave (escore: 6-10). Resultados: Vinte e quatro pediatras (31 anos, 92% sexo feminino) avaliaram 24 neonatos. A mediana do escore atribuído à dor do recém-nascido durante a punção do calcanhar foi 7,0 (intervalo interquartil: 5-8). Comparado ao período PRÉ, no período PÓS, o maior número de pediatras fixou o olhar na face inferior (63 vs. 92%; p=0,036) e o número de fixações visuais foi maior na face inferior (2,0 vs. 5,0; p=0,018). Não houve diferença no número e no tempo das fixações visuais de acordo com a intensidade da dor. Conclusões: À beira do leito, os pediatras mudam seu foco de atenção visual na face do recém-nascido após um procedimento doloroso, focando o olhar principalmente na parte inferior da face.

Translation, cross-cultural adaptation, and validation of health and self-management in diabetes questionnaire (HASMID-10) into Brazilian Portuguese

ABSTRACT BACKGROUND: Considering the ability of the health and self-management in diabetes questionnaire (HASMID-10) to verify the impact of self-management on diabetes, we highlight its relevance to scientific research and clinical applicability. However, to date, no study has been conducted to scientifically support its use in other languages. OBJECTIVE: To translate, cross-culturally adapt, and validate the HASMID-10 into the Brazilian Portuguese. DESIGN AND SETTING: A translation, cross-cultural adaptation, and validation study conducted at Ceuma University. METHODS: Study was conducted in accordance with the Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measures and Consensus-based Standards for the Selection of Health Measurement Instruments. We included participants of both sexes diagnosed with diabetes, aged between 18 and 64 years, and without cognitive deficits or any other limitations that would prevent them from answering the questionnaire. We assessed participants using the problem areas in diabetes (PAID) scale and HASMID-10. We assessed reliability using a test-retest model with a 7-day interval between assessments. We used intraclass correlation coefficient (ICC), 95% confidence interval (CI), standard error of measurement (SEM), minimum detectable difference (MDD), Spearman correlation coefficient, and floor and ceiling effects. RESULTS: Sample comprised 116 participants, most of whom were women, overweight, non-practitioners of physical activity, and nonsmokers. We observed significant correlations (P = 0.006; rho = −0.256) between the HASMID-10 and PAID, adequate reliability (ICC = 0.780) and internal consistency (Cronbach's alpha = 0.796). No ceiling or floor effects were observed. CONCLUSION: HASMID-10 has adequate measurement properties and may be used for Brazilians.

Development of an online radioactive xenon gas monitoring system for nuclear facilities / 中国辐射卫生

Objective Nowadays, radioactive xenon isotopes, including 131mXe, 133mXe, 133Xe, and 135Xe, are primarily released into the atmosphere through various reactor operation and major accidents of reactors. To improve the online monitoring capability of xenon in nuclear facilities and their gaseous effluents, a highly sensitive online xenon monitoring system was developed to monitor, warn, and alarm the activity concentration of radioactive xenon. Methods The online monitoring system for radioactive xenon gas in nuclear facilities was established using xenon membrane separation and concentration, xenon high-efficiency selective adsorption, and low-background gamma-ray spectrometry analysis methods. Results Under the operation mode of one-hour sampling and one-hour measuring, the minimum detectable activity concentration of the radioactive xenon online monitoring system for 133Xe was approximately (1.43 ± 0.03) Bq/m3. Conclusion This system can be effectively used for online monitoring of xenon activity concentration in nuclear facilities such as nuclear power plants and isotope production reactors, as well as in gaseous effluents. It helps improve the safety level of personnel, the environment, and nuclear facilities.

Validación de la escala de gravedad percibida de la violencia de pareja contra la mujer en población ecuatoriana

Introducción: La violencia de pareja contra la mujer (VPM) es un problema de salud pública a nivel global cuya prevalencia en Ecuador es de las más elevadas de Latinoamérica. La gravedad percibida de la VPM influye en las actitudes públicas hacia la VPM, como la aceptabilidad, el sentido de responsabilidad personal o la disposición a intervenir en casos de VPM. Método: En este estudio se presenta la adaptación de la escala española de gravedad percibida de la VPM (PS-IPVAW) al contexto cultural ecuatoriano, en una muestra de 652 participantes. Resultados: Los resultados mostraron que la escala PS-IPVAW tiene una buena consistencia interna, que sus ítems tienen una baja carga de deseabilidad social, que es invariante entre géneros y que se relaciona con la culpabilidad a la víctima, la aceptabilidad de la VPM y el sexismo hostil. Discusión: La escala PS-IPVAW es un instrumento con suficientes evidencias de fiabilidad y validez para evaluar la gravedad percibida de la VPM en Ecuador y representa un importante aporte para mejorar las estrategias de prevención, intervención y erradicación de este tipo de violencia en el contexto ecuatoriano.

Introduction: Intimate partner violence against women (IPVAW) is a global public health problem whose prevalence in Ecuador is among the highest in Latin America. The perceived severity of IPV influences public attitudes toward IPVAW, such as acceptability, sense of personal responsibility, or willingness to intervene in cases of IPV. Method: This study presents the adaptation of the Spanish scale of perceived severity of IPVAW (PS-IPVAW) to the Ecuadorian cultural context, in a sample of 652 participants.

Discussion: The PS-IPVAW scale showed adequate evidence.

Medición de la fuerza muscular en adultos como predictor de extubación en Unidades de Cuidados Intensivos. Revisión narrativa / Measurement of muscular strength in adults as a predicator of extubation in intensive care units. Narrative review

Resumen: Introducción: uno de los principales efectos de la ventilación mecánica invasiva es la lesión de los músculos respiratorios, específicamente, sobre el diafragma en el que pueden ocurrir alteraciones estructurales y funcionales que modifican parcial o totalmente su función. Durante la ventilación mecánica se produce un proceso de atrofia por desuso de dicho músculo. Por ello la utilidad clínica de la medición de la fuerza muscular diafragmática es importante para conocer si el paciente tiene la capacidad de activar los mecanismos protectores de la vía aérea para lograr la extubación exitosa y el retiro del ventilador mecánico en el menor tiempo posible. Objetivos: describir la medición de la fuerza muscular como predictor de la extubación en las unidades de cuidados intensivos. Material y métodos: se realizó una revisión de la literatura, entre 2011 y 2022. Resultados: los pacientes que son sometidos a ventilación mecánica invasiva prolongada generalmente desarrollan una afección muscular diafragmática, lo que se convierte en una problemática para el proceso de extubación temprana, por lo cual es vital conocer los métodos de medición de fuerza muscular como predictor de extubación.

Abstract: Introduction: one of the main effects of invasive mechanical ventilation is injury to the respiratory muscles, specifically the diaphragm. In which structural and functional alterations can occur that partially or totally modify its function. During mechanical ventilation, a process of disuse atrophy of said muscle occurs. Therefore, the clinical utility of measuring diaphragmatic muscle strength is important to know if the patient has the ability to activate the protective mechanisms of the airway to achieve successful extubation and removal of the mechanical ventilator in the shortest time possible. Objective: describe the measurement of muscle strength as a predictor of extubation in intensive care units. Material and methods: a literature review was carried out, carried out between 2011 and 2022. Results: patients who are subjected to prolonged mechanical ventilation generally develop a diaphragmatic muscle disorder, becoming a problem for the weaning, for it is important know the methods of measuring muscle strength.

Incidence and impacts of pain in intensive care units: systematic review / Incidência e impactos da dor em unidades de terapia intensiva: revisão sistemática

ABSTRACT BACKGROUND AND OBJECTIVES: In Intensive Care Units (ICU), patients are exposed to multiple procedures that can be painful, and health professionals are not always aware of the pain in these patients. Inadequate pain assessment and management, in turn, has been associated with several adverse outcomes, including an increased rate of infection, prolonged mechanical ventilation, hemodynamic disturbances, delirium, and compromised immunity. Thus, this study aimed to summarize the scientific evidence about the incidence and impacts of pain in critically ill patients. CONTENTS: A systematic review of observational studies (Pubmed and EMBASE databases) was performed with predetermined eligibility criteria. In the 32 studies included, it was identified that 10.1% to 61% of patients had pain at rest and 27.4% to 94% during procedures. In addition, there was evidence of improvement in patient outcomes after using validated instruments for pain measurement, including decreased length of ICU stay, duration of mechanical ventilation, mortality, delirium, adverse events, and disease severity. CONCLUSION: Through the present study, it was observed that pain is a common phenomenon in ICU and that its identification and management constitute a realistic goal and depend on the evaluation. Furthermore, pain appears to be associated with worse clinical outcomes. Therefore, efforts must be made to provide comprehensive care for critically ill patients, aiming not only at their survival, but also at alleviating their suffering.

RESUMO JUSTIFICATIVA E OBJETIVOS: Nas Unidades de Terapia Intensiva (UTI) os pacientes são expostos a múltiplos procedimentos que podem ser dolorosos, e nem sempre os profissionais de saúde estão alertas para a dor nesses pacientes. A avaliação e o manejo inadequado da dor, por sua vez, têm sido associados a uma série de resultados adversos, incluindo aumento da taxa de infecção, ventilação mecânica prolongada, distúrbios hemodinâmicos, delírio e imunidade comprometida. Dessa forma, este estudo teve como objetivo sumarizar as evidências científicas acerca da incidência e dos impactos da dor em pacientes críticos. CONTEÚDO: Foi realizada uma revisão sistemática de estudos observacionais (bases de dados Pubmed e EMBASE) com critérios de elegibilidade predeterminados. Nos 32 estudos incluídos, foi identificado que de 10,1% a 61% dos pacientes apresentaram dor em repouso, e de 27,4% a 94% apresentaram dor durante os procedimentos. Além disso, houve evidências de melhora nos resultados dos pacientes após o uso de instrumentos validados para a mensuração da dor, incluindo diminuição do tempo de permanência na UTI, duração da ventilação mecânica, mortalidade, delírio, eventos adversos e gravidade da doença. CONCLUSÃO: Através do presente estudo foi observado que a dor representa um fenômeno comum nas UTI e que a sua identificação e manejo constitui uma meta realista e dependente da avaliação. Além disso, a dor parece estar associada a piores desfechos clínicos. Sendo assim, deve-se voltar esforços para o cuidado integral ao paciente crítico, objetivando não só sua sobrevivência, mas também o alívio do seu sofrimento.
