Abstract Background: The Brief Measure of Preoperative Emotional Stress (B-MEPS) is a suitable screening tool for Preoperative Emotional Stress (PES). However, personalized decision-making demands practical interpretation of the refined version of B-MEPS. Thus, we propose and validate cut-off points on the B-MEPS to classify PES. Also, we assessed if the cut-off points screened preoperative maladaptive psychological features and predicted postoperative opioid use. Methods: This observational study comprises samples of two other primary studies, with 1009 and 233 individuals, respectively. The latent class analysis derived emotional stress subgroups using B-MEPS items. We compared membership with the B-MEPS score through the Youden index. Concurrent criterion validity of the cut-off points was performed with the severity of preoperative depressive symptoms, pain catastrophizing, central sensitization, and sleep quality. Predictive criterion validity was performed with opioid use after surgery. Results: We chose a model with three classes labeled mild, moderate, and severe. The Youden index points −0.1663 and 0.7614 of the B-MEPS score classify individuals, in the severe class, with a sensitivity of 85.7% (80.1%–90.3%) and specificity of 93.5% (91.5–95.1%). The cut-off points of the B-MEPS score have satisfactory concurrent and predictive criterion validity. Conclusions: These findings showed that the preoperative emotional stress index on the B-MEPS offers suitable sensitivity and specificity for discriminating the severity of preoperative psychological stress. They provide a simple tool to identify patients prone to severe PES related to maladaptive psychological features, which might influence the perception of pain and analgesic opioid use in the postoperative period.

Abstract Introduction Fibromyalgia is a complex, generalized, and diffuse chronic musculoskeletal pain. Pharmacological approaches are widely used to relieve pain and increase quality of life. Low-Dose Naltrexone (LDN) was shown to increase the nociceptive threshold in patients with fibromyalgia. Transcranial Direct Current Stimulation (tDCS) is effective for pain management. Objective The purpose of this study was to evaluate the analgesic and neuromodulatory effects of a combination of LDN and tDCS in patients with fibromyalgia. Methods This was a randomized, double-blinded, parallel, placebo/sham-controlled trial (NCT04502251; RBR-7HK8N) in which 86 women with fibromyalgia were included, and written informed consent was obtained from them. The patients were allocated into four groups: LDN + tDCS (n = 21), LDN + tDCS Sham (n = 22), placebo + tDCS (n = 22), and placebo+tDCS Sham (n = 21). The LDN or placebo (p.o.) intervention lasted 26 days; in the last five sessions, tDCS was applied (sham or active, 20 min, 2 mA). The following categories were assessed: sociodemographic, Visual Analog Pain Scale (VAS), Pain Catastrophizing Scale (PCS), State-Trait Anxiety Inventory (STAI), Fibromyalgia Impact Questionnaire (FIQ), Beck Depression Inventory (BDI-II), Profile of Chronic Pain Scale (PCP:S), Pain Pressure Threshold (PPT), and Conditioned Pain Modulation (CPM). Blood samples were collected to analyze BDNF serum levels. Results At baseline, no significant difference was found regarding all measurements. VAS pain was significantly reduced in the LDN + tDCS (p = 0.010), LDN + tDCS Sham (p= 0.001), and placebo+tDCS Sham (p= 0.009) groups. In the PCP:S, the LDN+tDCS group showed reduced pain frequency and intensity (p= 0.001), effect of pain on activities (p= 0.014) and emotions (p= 0.008). Depressive symptoms reduced after all active interventions (p > 0.001). Conclusion Combined LDN+tDCS has possible benefits in reducing pain frequency and intensity; however, a placebo effect was observed in pain using VAS, and further studies should be performed to analyze the possible association. complex generalized life LowDose Low Dose (LDN (tDCS management randomized doubleblinded, doubleblinded double blinded, blinded double-blinded parallel placebo/shamcontrolled placeboshamcontrolled placebo/sham controlled sham NCT04502251 NCT (NCT04502251 RBR7HK8N RBRHKN RBR 7HK8N HK N RBR-7HK8N 8 included them groups n 21, 21 , 21) 22, 22 22) placebotDCS 21. . p.o. po p o (p.o. days sessions min mA. mA mA) assessed sociodemographic (VAS) PCS, PCS (PCS) StateTrait State Trait STAI, STAI (STAI) FIQ, FIQ (FIQ) BDIII, BDIII BDI II (BDI-II) PCPS, PCPS PCP S (PCP:S) PPT, PPT (PPT) CPM.

Abstract Objectives The Pain Catastrophizing Scale-Child version (PCS-C) allows to identify children who are prone to catastrophic thinking. We aimed to adapt the Brazilian version of PCS-C (BPCS-C) to examine scale psychometric properties and factorial structure in children with and without chronic pain. Also, we assessed its correlation with salivary levels of Brain-Derived Neurotrophic factor (BDNF). Methods The Brazilian version of PCS-C was modified to adjust it for 7-12 years old children. To assess psychometric properties, 100 children (44 with chronic pain from a tertiary hospital and 56 healthy children from a public school) answered the BPCS-C, the visual analogue pain scale, and questions about pain interference in daily activities. We also collected a salivary sample to measure BDNF. Results We observed good internal consistency (Cronbach’s value = 0.81). Parallel analysis retained 2 factors. Confirmatory factor analysis of our 2-factor model revealed consistent goodness-of-fit (IFI = 0.946) when compared to other models. There was no correlation between visual analogue pain scale and the total BPCS-C score; however, there was an association between pain catastrophizing and difficulty in doing physical activities in school (p= 0.01). BPCS-C total scores were not different between groups. We found a marginal association with BPCS-C (r= 0.27, p= 0.01) and salivary BDNF levels. Discussion BPCS-C is a valid instrument with consistent psychometric properties. The revised 2-dimension proposed can be used for this population. Children catastrophism is well correlated with physical limitation, but the absence of BPCS-C score differences between groups highlights the necessity of a better understanding about catastrophic thinking in children.

Abstract Background: The postoperative care transition from the postanesthetic recovery room (PACU) to the common ward or even home discharge represents a critical step of the surgical patients’ handover. Although some systems have been proposed to measure the ability to discharge after an anesthetic-surgical procedure effectively, there is no consensus defining which variables should necessarily be evaluated by these instruments. The instruments routinely used do not evaluate important domains for discharge and are laborious to fill, which compromises the professionals’ adhesion. The objectives are to describe the creation of a new recovery room discharge tool (SAMPE checklist) and determine the degree of agreement of the new tool with two classical scales. Methods: In a cross-sectional observational study, 997 patients were selected from the general population undergoing a wide range of surgical procedures in a quaternary care hospital. At 90 minutes after leaving the operating room (OR), patients were evaluated and information was collected to fill out the new SAMPE checklist and two other scores (Aldrete and White) to examine the degree of agreement between them. Results: SAMPE checklist has presented a satisfactory agreement with the White score and lower agreement with Aldrete modified score. Conclusion: This new instrument, as demonstrated in this study with nearly 1000 patients from different contexts, is easy to apply, has high adhesion potential, and can be considered a new option to formalize the discharge from the recovery room.

ABSTRACT Objectives: To assess disordered eating, hunger and satiety perceptions in women with fibromyalgia (FM) compared to healthy controls (HC) and their association with biomarkers of brain plasticity (brain-derived neurotrophic factor (BDNF) and S100 calcium-binding protein B (S100B)). Subjects and methods: Cross-sectional exploratory study. The sample included FM (n = 20) and HC (n = 19), matched to age and waist perimeter. Dysfunctional eating was assessed through the Three Factor Eating Questionnaire and Eating Disorders Examination with a questionnaire. Hunger and satiety levels were rated by a Numerical Scale. Serum leptin, S100B and BDNF were analyzed. Results: The MANCOVA analysis showed that the mean of Emotional Eating rates was 30.65% higher in FM compared to HC ( p = 0.015). Eating, shape and weight concerns were 77.77%, 57.14% and 52.22% higher in FM ( p = <0.001) compared to HC, respectively. Moreover, the FM group reported higher scores for feeling of hunger “[5.2 (±2.9) vs. 4.8 (±2.0); p = 0.042] and lower scores for satiety [7.0 (±1.7) vs . 8.3 (±1.0); p = 0.038]. In the FM group, serum BDNF was negatively associated with hunger (r = - 0.52; p = 0.02), while S100B was positively associated with hunger scores (r = 0.463; p = 0.004). Conclusion: The present findings support the hypothesis that the association between FM and obesity can be mediated by a hedonistic pathway. Further research is needed.

Abstract Fibromyalgia is a syndrome characterized by chronic pain related to the musculoskeletal system. Patients feel incapable and show catastrophic thoughts (exaggeration of the sensations) related to painful events. This study aimed to compare catastrophic thoughts of pain between daughters of women with fibromyalgia and daughters of women without fibromyalgia, no daughter having the syndrome. It was a case-control study in which 76 women were included: 38 daughters of women diagnosed with fibromyalgia (case group), and 38 daughters of women without fibromyalgia (control group). The Brazilian versions of the Profile of Chronic Pain: Screen, the Pittsburgh Sleep Quality Index, the Pain Catastrophizing Scale, Resilience Scale, Beck Depression Inventory-II, and the State-Trait Anxiety Inventory were used. Data were tabulated and analyzed using SPSS 20.0. Continuous variables were compared between the groups using the Mann-Whitney U test or Student’s t-test for independent samples. A significant difference was considered at p< 0.05. Regarding catastrophism, the case group had higher total catastrophism compared to the control group (p= 0.025). Daughters of patients with fibromyalgia showed higher rumination and magnification levels related to pain (p= 0.028 and p= 0.007, respectively) but did not show hopelessness. This study concludes that daughters of women with fibromyalgia are more likely to have symptoms of fibromyalgia due to their visualization of the syndrome. This indicates that emotional aspects may induce changes, and additional research on an individual basis is necessary.

RESUMO JUSTIFICATIVA E OBJETIVOS: A expressão do fator de crescimento neural (NGF) em neurônios de diâmetro largo pode representar um papel importante na plasticidade sináptica neuronal e na reorganização da função neuronal após lesão neural. A estimulação transcraniana por corrente contínua (ETCC) é um método não invasivo de estimulação cerebral e representa uma ferramenta promissora para o manejo da dor, pois promove neuroplasticidade no sistema central, podendo ser combinada com outras intervenções. O objetivo foi investigar os efeitos da ETCC nos níveis de NGF em estruturas do sistema nervoso central e periférico de ratos submetidos a um modelo de dor neuropática (DN). MÉTODOS: A constrição crônica (CCI) do nervo isquiático foi utilizada para indução do modelo de DN. Na cirurgia sham, o nervo foi exposto, no entanto não houve constrição do nervo. O grupo controle não foi submetido ao procedimento cirúrgico. Após estabelecimento da DN, os grupos tratados foram submetidos a ETCC 0,5 mA/20min/dia/8 dias. Os níveis de NGF no córtex cerebral, medula espinal e nervo isquiático foram mensurados pela técnica de ELISA 48 horas e 7 dias após o final do tratamento. RESULTADOS: O modelo de dor CCI aumentou os níveis de NGF nas três estruturas analisadas, evidenciando a importância desta neurotrofina na dor neuropática. Por outro lado, não houve efeito da ETCC nos níveis de NGF central e periférico, descartando o papel desta neurotrofina no efeito analgésico da ETCC. CONCLUSÃO: Efeitos da ETCC sobre vias nociceptivas não estão diretamente relacionados com a sinalização do NGF neste modelo de dor crônica.

ABSTRACT BACKGROUND AND OBJECTIVES: The expression of nerve growth factor (NGF) in the large-size neurons may represent a key role in the neuronal synaptic plasticity and re-organization of neuronal function after a nerve injury. Transcranial direct current stimulation (tDCS) is a non-invasive method of cerebral stimulation and represents a promising tool to pain management since it promotes neuroplasticity in the central system, and it can be combined with other interventions. The aim was to investigate the effects of tDCS in the NGF levels in central and peripheral nervous system structures of rats submitted to a neuropathic pain (NP) model. METHODS: The chronic constriction injury (CCI) of sciatic nerve was used for the induction of NP. For sham surgery, the sciatic nerve was exposed, but without any ligation. The control group did not undergo surgical procedure. After the establishment of NP, treated groups were subjected to tDCS treatment 0.5 mA/20min/day/8 days. NGF levels in cerebral cortex, spinal cord and sciatic nerve were determined by sandwich-ELISA at 48 hours and 7 days after the end of treatment. RESULTS: The CCI model increased NGF levels in all three structures analyzed at long-lasting time, evidencing the importance of this neurotrophin in neuropathic pain condition. On the other hand, there was no tDCS effect in the central and peripheral NGF levels discarding the participation of this neurotrophin in the analgesic tDCS effect. CONCLUSION: tDCS modulation effects of nociceptive pathways seem not to be linked to the NGF signaling in this chronic pain model.

RESUMO JUSTIFICATIVA E OBJETIVOS: Para investigar métodos mais seguros e eficazes para o manejo da artrite reumatoide, avaliou-se o efeito do tratamento com dexametasona (DEX, 0,25mg/kg) combinado com estimulação transcraniana por corrente contínua (ETCC) sobre parâmetros comportamentais e bioquímicos de ratos submetidos a um modelo de artrite reumatoide. MÉTODOS: Trinta e seis ratos Wistar foram alocados em 4 grupos: controle+DEX (CTRL+DEX), artrite+DEX (AR+DEX), artrite+DEX+sham-ETCC (AR+DEX+sham-ETCC) e artrite+DEX+ETCC (AR+DEX+ETCC). O modelo de artrite foi induzido pela administração de complete Freund’s adjuvant (CFA) na pata. Edema na pata e a alodínia mecânica foram avaliadas por pletismômetro e teste de von Frey, respectivamente. 14 dias após injeção de CFA, ratos foram tratados por 8 dias (DEX e/ou ETCC). Atividade locomotora foi avaliada pelo teste do campo aberto. TNF-alfa (hipocampo e medula espinal) e BDNF (córtex e tronco) foram mensurados por ELISA. RESULTADOS: Nas medições pré-tratamento, ratos com artrite exibiram aumento de o inchaço articular e alodínia mecânica comparados ao grupo controle, confirmando o estabelecimento de modelo de dor crônica. Também se observou discreto efeito antinociceptivo da dexametasona combinada com ETCC no modelo de artrite. O modelo de dor induziu um aumento no comportamento de grooming e reduziu os níveis de TNF-alfa no hipocampo; estes efeitos foram revertidos nos grupos sham- e ETCC ativo. Entretanto, não foram observados efeitos da DEX ou ETCC nos níveis de BDNF no córtex cerebral ou no tronco encefálico. CONCLUSÃO: Apesar dos discretos efeitos observados, não se pode descartar a ETCC como uma abordagem terapêutica não farmacológica para o manejo da dor crônica inflamatória na artrite reumatoide.

ABSTRACT BACKGROUND AND OBJECTIVES: To pursue safer and more effective treatments for rheumatoid arthritis, the effect of dexamethasone treatment (DEX, 0.25mg/kg) combined with transcranial direct current stimulation (tDCS) in the behavior and neurochemical parameters of arthritic rats was evaluated. METHODS: Thirty-six Wistar rats were divided into four groups: control+DEX (CTRL+DEX), arthritis+DEX (RA+DEX), arthritis+DEX+sham-tDCS (RA+DEX+sham-tDCS) and arthritis+DEX+tDCS (RA+DEX+tDCS). The arthritic model (RA) was induced by complete Freund’s adjuvant (CFA) paw administration. Paw edema and mechanical allodynia were assessed by plethysmometer and von Frey apparatus, respectively. Fourteen days after the CFA injection, rats received the treatment for eight days (DEX and/or tDCS). Behavioral parameters were measured with the Open-Field test. ELISA was used to evaluate hippocampal and spinal cord tumor necrosis factor (TNF-α) levels, cerebral cortex and brainstem BDNF levels. RESULTS: In pre-treatment measurements, arthritic rats presented an increase in joint swelling and mechanical allodynia when compared to the control group, confirming chronic pain establishment. A slight antinociceptive effect of dexamethasone combined with tDCS in the pain model was observed. The pain model significantly induced an increase in the grooming behavior and a reduction in the spinal cord and hippocampal TNF-α levels; these effects were reverted in the sham- and active-tDCS-treated rats. However, no effects of DEX or tDCS were observed in the BDNF levels in the cerebral cortex and brainstem. CONCLUSION: Despite the small effect observed, tDCS treatment cannot be discarded as a non-pharmacological adjuvant technique for inflammatory chronic pain treatment.

Abstract Background: Fibromyalgia (FM) is a musculoskeletal chronic pain syndrome that impacts negatively patient's daily lives. Its pathogenesis is characterized by a complex relationship between biological and psychosocial factors not fully understood yet. Pain catastrophizing is associated with FM and is an important predictor of outcomes. This study aimed to answer two questions: (i) whether the allele and genotype frequencies of BDNF Val66Met (rs6265) polymorphism differs between FM patients and healthy controls (HC); and (ii) if the BDNF Val66Met polymorphism is a factor that predicts pain catastrophizing in FM. Methods: In a cross-sectional design, 108 FM patients and 108 HC were included. FM patients responded to the Brazilian Portuguese version of the Pain Catastrophizing Scale (BP-PCS) to assess pain catastrophizing, as well as other validated tools for anxiety (The State-Trait Anxiety Inventory - STAI), depression (Beck Depression Inventory II -BDI-II) and functional aspects (Fibromyalgia Impact Questionnaire - FIQ; Central Sensitization Inventory validated and adapted for Brazilian population - CSI-BP; Pittsburgh Sleep Quality Index - PSQI; and Resilience Scale). All subjects were genotyped for the BDNF Val66Met polymorphism. Results: Val allele was significantly more frequent in FM patients compared to the control group (p < 0.05). Also, FM patients with Val/Val genotype showed more pain catastrophizing thoughts, and this genotype was significantly associated with magnification and rumination dimensions of BP-PCS (p < 0.05). Furthermore, there were significant differences in levels of anxiety and symptoms of depression, years of education, and the functional situation between the FM and control groups. Conclusions: The findings show an association of BDNF Val66Met polymorphism with pain catastrophizing in FM, which opens new avenues to comprehend the interplay between molecular genetic characteristics and neuroplasticity mechanisms underpinning FM.

Resumo Introdução Quando comparada a procedimentos eletivos, a morbimortalidade associada às cirurgias de urgência ou emergência é alta. Escores de risco perioperatório identificam o caráter não eletivo como fator independente de complicações e morte. O presente estudo objetiva caracterizar a população submetida a cirurgias não eletivas no Hospital de Clínicas de Porto Alegre e identificar fatores clínicos e cirúrgicos associados à morte em 30 dias no pós-operatório. Metodologia Coorte prospectiva de 187 pacientes submetidos a cirurgias não eletivas entre abril e maio de 2014 no Hospital de Clínicas de Porto Alegre. Avaliaram-se dados relacionados ao paciente, situações de risco pré-operatórias e informações do âmbito cirúrgico. Mensurou-se óbito em 30 dias como desfecho primário. Resultados A média de idade da amostra foi 48,5 anos; 84,4% dos indivíduos apresentavam comorbidades. O desfecho primário foi observado em 14,4% dos casos, laparotomia exploradora foi o procedimento com maior mortalidade (47,7%). Após regressão logística multivariada, identificaram-se idade (odds ratio [OR] 1.0360, p < 0,05), anemia (OR 3.961, p < 0,05), insuficiência renal aguda ou crônica agudizada (OR 6.075, p < 0,05) e sepse (OR 7.027, p < 0,05) como os fatores de risco relacionados ao paciente significativos para mortalidade, além da categoria cirurgia de grande porte (OR 7.502, p < 0,05). Conclusão A elevada taxa de mortalidade encontrada pode refletir a alta complexidade dos pacientes da instituição. O conhecimento do perfil dos pacientes atendidos auxilia na definição de prioridades de gerenciamento, sugere a necessidade de criação de linhas de cuidado específicas para grupos identificados como de alto risco, a fim de reduzir complicações e óbitos no perioperatório.

Abstract Introduction Morbidity and mortality associated with urgent or emergency surgeries are high compared to elective procedures. Perioperative risk scores identify the non-elective character as an independent factor of complications and death. The present study aims to characterize the population undergoing non-elective surgeries at the Hospital de Clínicas de Porto Alegre and identify the clinical and surgical factors associated with death within 30 days postoperatively. Methodology A prospective cohort study of 187 patients undergoing elective surgeries between April and May 2014 at the Hospital de Clínicas, Porto Alegre. Patient-related data, pre-operative risk situations, and surgical information were evaluated. Death in 30 days was the primary outcome measured. Results The mean age of the sample was 48.5 years, and 84.4% of the subjects had comorbidities. The primary endpoint was observed in 14.4% of the cases, with exploratory laparotomy being the procedure with the highest mortality (47.7%). After multivariate logistic regression, age (odds ratio [OR] 1.0360, p < 0.05), anemia (OR 3.961, p < 0.05), acute or chronic renal insufficiency (OR 6.075, p < 0.05), sepsis (OR 7.027, p < 0.05), and patient-related risk factors for mortality, in addition to the large surgery category (OR 7.502, p < 0.05) were identified. Conclusion The high mortality rate found may reflect the high complexity of the institution's patients. Knowing the profile of the patients assisted helps in the definition of management priorities, suggesting the need to create specific care lines for groups identified as high risk in order to reduce perioperative complications and deaths.

RESUMO Objetivo O manejo da doença de Parkinson (DP) é usualmente alcançado com sucesso com o tratamento farmacológico apropriado. Entretanto, os pacientes com DP podem manifestar sintomas neuropsiquiátricos secundários à terapêutica, como a síndrome de descontrole dos impulsos (SDI), que se apresenta como o jogar patológico, a hipersexualidade, o comprar, beber ou comer compulsivos. Traduzimos e validamos a versão em português do questionário padrão-ouro para identificação de transtornos impulsivo-compulsivos na DP (QUIP-CS) para identificar nesses pacientes a presença de SDI. Métodos Foram realizadas a tradução, a retrotradução e a submissão do instrumento ao desenvolvedor deste, que aprovou a nova versão comparando esta à sua, que já está validada, sem a perda das suas propriedades originais. Após, a versão em português foi administrada a 30 pacientes com o diagnóstico de DP. Eles também foram solicitados a classificar o nível de compreensibilidade das questões, graduando-as de 1 a 5. Resultados O nível médio de compreensão foi 4,06 ± 0,69 DP, considerando-se 3 ou mais como aceitável. Nenhum paciente respondeu 1 ou 2. Conclusão Os nossos resultados para a versão em português da QUIP-CS mostraram que essa versão, traduzida e corrigida, foi facilmente compreendida e aplicada pelos próprios pacientes.

ABSTRACT Objective Parkinson’s disease (PD) management is usually successfully reached with proper pharmacological treatment. However, PD patients can manifest neuropsychiatric symptoms secondary to medical therapy, including impulse control disorders (ICD), presenting as pathological gambling, hypersexuality, compulsive buying, drinking or eating disorders. We translated and validated the Portuguese version of the gold-standard questionnaire Parkinson’s Disease Impulsive-Compulsive Disorders Questionnaire, or (QUIP) for identifying ICDs in PD patients. Methods Translation, back translation and submission to instrument developer was performed, that approved its new version comparing it to his original, validated version, with no loss of it’s original properties. Then, the Portuguese version was administered to 30 PD patients. They also were asked to rate from 1 to 5 the level of comprehensibility of the questions. Results The average level of comprehension was 4.06 ± 0.69 DP, considering 3 or more as acceptable. No patient has answered 1 or 2. Conclusion Our results on Portuguese version of QUIP-CS show that QUIP-CS translated and corrected version was easily understood and easily self-applied.

Resumo: O objetivo deste estudo foi identificar perfis de resiliência em paciente com dor crônica. Utilizando a Análise de Classes Latentes, em uma amostra de 414 pacientes com dor crônica musculoesquelética, foram identificados três perfis: resiliência primária (40%), composto por indivíduos de até 40 anos, que têm alta escolaridade, buscam os cuidados médicos, não trabalham e não apresentam sintomas de estresse psicológico; resiliência secundária (30%), composto por mulheres com mais de 54 anos, que têm baixo nível de escolaridade, buscam cuidados médicos, não trabalham e apresentam baixa probabilidade de experimentar sintomas de estresse psicológico; resiliência terciária (29%), composto por mulheres com médio nível de escolaridade, idade entre 40 e 54 anos, que trabalham, não buscam cuidados médicos e têm alta probabilidade de experimentar sintomas de estresse psicológico. Os três perfis revelam caminhos distintos de resiliência na dor crônica com relevância para prática clínica, destacando a atuação multidisciplinar nos cuidados ao paciente com dor crônica.

Abstract: The aim of this study was to identify resilience profiles of patients with chronic pain. Using latent class analysis in a sample of 414 patients with chronic musculoskeletal pain, three profiles were identified: primary resilience (40%), consisting of individuals 40 years or younger with high education, who seek medical care, are not working, and without symptoms of psychological stress; secondary resilience (30%), consisting of women over 54 years of age with low schooling, who seek medical care, are not working, and with low likelihood of symptoms of psychological stress; tertiary resilience (29%), women with medium schooling, 40 to 54 years old, working, who do not seek medical care, and with a high likelihood of symptoms of psychological stress. The three profiles display different paths of resilience in chronic pain that are relevant to clinical practice, highlighting the importance of multidisciplinary care for patients with chronic pain.

Utilizando el análisis de clases latentes, en una muestra de 414 pacientes con dolor crónico musculoesquelético, fueron identificados tres perfiles: resiliencia primaria (40%), compuesto por individuos de hasta 40 años, que tienen una alta escolaridad, buscan cuidados médicos, no trabajan y no presentan síntomas de estrés psicológico; resiliencia secundaria (30%), compuesto por mujeres con más de 54 años, que tienen bajo nivel de escolaridad, buscan cuidados médicos, no trabajan y presentan baja probabilidad de experimentar síntomas de estrés psicológico; resiliencia terciaria (29%), compuesto por mujeres con medio nivel de escolaridad, edad entre 40 y 54 años, que trabajan, no buscan cuidados médicos y tienen una alta probabilidad de experimentar síntomas de estrés psicológico. Los tres perfiles revelan caminos distintos de resiliencia en el dolor crónico, con relevancia para la práctica clínica, destacando la actuación multidisciplinaria en los cuidados al paciente con dolor crónico.

Nos últimos anos, a compreensão dos mecanismos e consequentemente do diagnóstico da dor neuropática (DN) têm se tornado cada vez mais claros na prática clínica. Entretanto, o tratamento desta condição continua sendo um desafio. Uma das razões para tal dificuldade é diversidade de mecanismos envolvidos na geração e perpetuação da DN. Na presente revisão, os autores discutem várias modalidades de tratamento para DN pouco utilizadas na prática clínica diária. Para isso, selecionamos evidências clínicas positivas de abordagens para DN consideradas não-convencionais e do tipo “SFBR” (Seguro, Fácil, Barato e Racional). O objetivo desta revisão não é estabelecer o “estado da arte” ou diretrizes rígidas para o tratamento da DN. Diferente disso, pretendemos apenas trazer aos leitores novas possibilidades de tratamento assim como motivar pesquisadores a confirmar estes resultados preliminares, mas promissores para o alívio da DN.

In the last few years the understanding of mechanisms and, consequently, the diagnosis of neuropathic pain (NP) has becoming progressively clearer in clinical practice. However, the treatment of such condition remains challenging so far. One of the reasons for such difficulty is the diversity of mechanisms involved in NP generation and its persistency. In the present review we discuss several treatment modalities for NP that are scantily applied in daily clinical practice. For that, we collected positive clinical evidence of unusual and SECS (Safe, Easy, Cheap, and Sensible) approaches for NP. The aim of this review is not to establish the “state of the art” or rigid guidelines for NP treatment. In a different way, we only want bring new possibilities of treatment to the readers and also to motivate investigators to confirm those positive preliminary but promising results for NP reliev.
