ABSTRACT

Waltheria indica (Malvaceae) is a plant popularly used in folk medicine by traditional African and indigenous communities, and in various countries worldwide, to treat general inflammation. Several biological activities of this plant have been reported, including acetylcholinesterase inhibition and potential anti-human immunodeficiency virus (HIV), antinociceptive, analgesic, antifungal, anticancer, anti-inflammatory, leishmanicidal, trypanocidal, antioxidant, and antibacterial activities. The chemical profile of Waltheria indica was assessed by dereplication analysis using UPLC-MS/MS, and data acquisition was performed using chemoinformatics tools, such as Mass Spectrometry-Data Independent AnaLysis (MS-DIAL) and MS-FINDER softwares. The preprocessed data were sent to the GNPS to build a feature-based molecular network (FBMN). Thirty-three 4-quinolone alkaloids were annotated in the extracts and fractions of stems and roots, whereas 12 were annotated in the extracts and fractions of flowers and leaves. This represents an inaugural chemical investigation study employing UPLC-Q-TOF-MS/MS analysis, along with a molecular network approach, within this species and genus.

ABSTRACT

Background: In real-world experience, the number of patients using vedolizumab as first-line biological therapy was low. We aimed to evaluate the effectiveness and safety of vedolizumab in mild-to-moderate Crohn's disease (CD) biologic-naïve patients. Methods: We performed a retrospective multicentric cohort study with patients who had clinical activity scores (Harvey-Bradshaw Index [HBI]) measured at baseline and weeks 12, 26, 52, as well as at the last follow-up. Clinical response was defined as a reduction ≥3 in HBI, whereas clinical remission as HBI ≤4. Mucosal healing was defined as the complete absence of ulcers in control colonoscopies. Kaplan-Meier survival analysis was used to assess the persistence with vedolizumab. Results: From a total of 66 patients, 53% (35/66) reached clinical remission at week 12. This percentage increased to 69.7% (46/66) at week 26, and 78.8% (52/66) at week 52. Mucosal healing was achieved in 62.3% (33/53) of patients. Vedolizumab was well tolerated, and most adverse events were minor. During vedolizumab treatment, 3/66 patients underwent surgery. Conclusions: This study demonstrates the effectiveness and safety of vedolizumab as a first-line biological agent in patients with mild-to-moderate CD.

ABSTRACT

BACKGROUND & AIMS: Changes in dietary habits including increased intake of refined sugars and fats and decreased intake of fiber have been suggested as potential risk factors for the development of inflammatory bowel diseases (IBD). Bioelectrical impedance analysis-derived phase angle (PhA) has been gaining attention in the clinical evaluation of nutritional status. In this study, we for the first time investigated the relationship of PhA and ultra-processed food intake with oxidative stress, body composition and biochemical parameters in adult patients with IBD. METHODS: Body composition and PhA were evaluated through electrical bioimpedance. Nitrite (Nox), myeloperoxidase (MPO), glutathione (GSH), malondialdehyde (MDA) and superoxide dismutase (SOD) levels were determined in both groups. Food consumption was obtained by a food frequency questionnaire (FFQ). RESULTS: In comparison with the control group, the IBD group had increased (p < 0.05) concentrations of Nox (19.95 ± 1.4 vs. 35.43 ± 7.7 µM), MDA (0.70 ± 0.31 vs. 4.56 ± 0.62 nmol/L), and GSH (9.35 ± 0.38 vs. 10.74 ± 0.51 mg NPSH/µL plasma). PhA was positively correlated with GSH (R2:0.22; p:0.02) and SOD (R2:0.25; p:0.01). IBD patients ingested higher amounts of ultra-processed foods (IBD:17.04 ± 2.76 vs. Control:24.88 ± 2.30%). However, IBD patients had better consumption of unprocessed or minimally processed foods (IBD:79.06 ± 3.07 vs. Control:67.83 ± 2.32%). We found a positive correlation between ultra-processed food consumption and MDA (R2 0.43; p:0.01). CONCLUSIONS: PhA may be a practical and effective measure in clinical follow-up of IBD patients, being associated with bilirubin levels and antioxidant enzymes. Also, we recommend evaluating consumption of ultra-processed foods, since this was related with increasing oxidative stress markers in clinical follow-up of IBD patients.

ABSTRACT

BACKGROUND: Melioidosis is a serious disease caused by the bacterium Burkholderia pseudomallei which affects humans and animals. It results in a wide spectrum of clinical manifestations, mainly in the respiratory tract, progressing to septic shock and death. CASE PRESENTATION: Herein, we present a series of seven patients (median age: 41 years) with confirmed melioidosis, treated at a public hospital in Piauí State, Brazil between 2019 and 2021. The most common clinical presentations were fever, cough, pneumonia, and abdominal pain. The mean duration of antibacterial therapy with 1 g of meropenem was 28.6 ± 1.1 days. Six patients recovered and one died. The mean hospitalization time was 51.0 ± 39.2 days. CONCLUSIONS: Melioidosis is an emerging infectious disease in Brazil. Health professionals in endemic areas need to be aware of the clinical presentation and appropriate clinical management of the disease because early diagnosis and early initiation of antibiotic therapy can be life-saving.

ABSTRACT

The zebrafish is an animal model of increasing use in many biomedical fields of study, including toxicology, inflammation, and tissue regeneration. In this paper, we have investigated the inflammatory effects of Loxosceles intermedia's venom (LIV) on zebrafish, as well as the effects of Maresin 2 (Mar2) and Resolvin D5 (RvD5), two specialized pro-resolving mediators (SPMs), in the context of tissue regeneration after fin fold amputation. Furthermore, increasing concentrations of LIV (250-2000 ng) were assayed for their haemolytic effects in vitro, and, afterwards, the same concentrations were evaluated in vivo, when injected intraperitoneally. LIV caused haemolysis in human red blood cells (RBCs), but not in zebrafish RBCs. The survival curve was also not altered by LIV injection, regardless of venom dosage. Histological analysis of renal and hepatic tissues, as well as the whole animal, revealed no pathological differences between LIV-injected and PBS-injected groups. Fin fold regeneration was not altered between LIV-injected and control groups, nor in the presence of MaR2 and RvD5. Results of swimming behavioral analysis also did not differ between groups. Moreover, in silico data indicated differences between human and zebrafish cell membrane lipid constitutions, such as in phospholipases D preferred substrates, that could lead to the protection of zebrafish against LIV. Although our data implies that zebrafish cannot be used as a toxicological model for LIV studies, the absence of observed toxicological effects paves the way for the comprehension of the venom's mechanism of action in mammals and the fundamental evolutionary processes involved.

ABSTRACT

OBJECTIVES: In this review, we systematically assess whether dietary interventions are effective in attenuating inflammatory biomarkers in IBDs based on clinical trials available in the literature. RESEARCH METHODS & PROCEDURES: This review was conducted in accordance with the guidelines of the PRISMA. We used the PubMed and SciVerse Scopus databases and the Cochrane collaboration tool to assess the risk of bias in clinical trials. The PICO (patient, intervention, comparison, and outcomes) strategy was used, with the descriptors: "Inflammatory bowel disease", "Crohn's disease", "cd", "ibd", "ulcerative colitis", "uc", "Diet", "Diet Habits", "Feeding", "Nutrients", "Food Intake", "Dietary patterns", "Inflammations", "Inflammation", "acute-phase proteins", "C-reactive protein", "interleukins", "tumor necrosis factor-alpha" and "inflammatory response". There is no conflict of interest. DATA ANALYSIS: Fifteen studies were included, with a total of 627 participants. Of the total studies included, seven showed a reduction in some inflammatory markers in response to dietary interventions. This review was registered with the PROSPERO platform under number: CRD42021235150. CONCLUSIONS: The results presented in this review reveal that dietary intervention with specific characteristics may be important during the treatment of the inflammatory process in patients with IBDs.

ABSTRACT

OBJECTIVE: The executive functions (EF) and emotion regulation (ER) and their relationship with the substance use disorder (SUD) were analyzed. METHODS: A cross-sectional design was used. The sample consisted of 130 volunteers divided into three groups: group 01 (n = 60), composed of participants who did not meet the diagnostic criteria for any type of SUD; group 02 (n = 51), with users with alcohol and/ or tobacco use disorder; group 03 (n = 19), with users with multiple substance use disorder, including at least one illicit substance. RESULTS: Group 02 presented worse performance in EF and ER when compared to group 01, and showed a significant correlation between the working memory and the use of maladaptive ER. Group 03 showed great losses in EF and ER when compared to the other groups. CONCLUSION: This study supports the idea that EF, ER and SUD are related. In addition, it was observed that people with SUD had worse performance in EF and ER when compared to people without SUD, greater damage being observed in people with SUD of polysubstances.


OBJETIVO: Analisaram-se as funções executivas (FE) e a regulação emocional (RE) e a sua relação com o transtorno por uso de substâncias (TUS). MÉTODOS: Utilizou-se um delineamento transversal. A amostra foi composta por 130 voluntários, divididos em três grupos: grupo 01 (n = 60), composto pelos participantes que não preenchiam os critérios diagnósticos para nenhum tipo de TUS; grupo 02 (n = 51), com os entrevistados com TUS de álcool e/ou cigarro; grupo 03 (n = 19), com os voluntários com TUS de polissubstâncias, incluindo pelo menos uma substância ilícita. RESULTADOS: O grupo 02 apresentou pior desempenho nas FE e na RE, quando comparado ao grupo 01, e exibiu uma correlação significativa entre a memória de trabalho e o uso de RE desadaptativa. O grupo 03 apresentou maior prejuízo nas FE e na RE, quando comparado aos demais grupos. CONCLUSÃO: Este estudo apoia a ideia de que as FE, a RE e o TUS estão relacionados. Além disso, observou-se que as pessoas com TUS apresentaram pior desempenho nas FE e na RE, quando comparadas com as pessoas sem o TUS, sendo as com TUS de polissubstâncias com maior prejuízo.

ABSTRACT

BACKGROUND: Crohn's disease (CD) and ulcerative colitis (UC) are inflammatory bowel diseases (IBDs) with a remission-relapsing presentation and symptomatic exacerbations that have detrimental impacts on patient quality of life and are associated with a high cost burden, especially in patients with moderate-to-severe disease. The Real-world Data of Moderate-to-Severe Inflammatory Bowel Disease in Brazil (RISE BR) study was a noninterventional study designed to evaluate disease control, treatment patterns, disease burden and health-related quality of life in patients with moderate-to-severe active IBD. We report findings from the prospective follow-up phase of the RISE BR study in patients with active UC or CD. AIM: To describe the 12-mo disease evolution and treatment patterns among patients with active moderate-to-severe IBD in Brazil. METHODS: This was a prospective, noninterventional study of adult patients with active Crohn's disease (CD: Harvey-Bradshaw Index ≥ 8, CD Activity Index ≥ 220), inadequate CD control (i.e., calprotectin > 200 µg/g or colonoscopy previous results), or active ulcerative colitis (UC: Partial Mayo score ≥ 5). Enrollment occurred in 14 centers from October 2016 to February 2017. The proportion of active IBD patients after 9-12 mo of follow-up, Kaplan-Meier estimates of the time to mild or no activity and a summary of treatment initiation, discontinuation and dose changes were examined. RESULTS: The study included 118 CD and 36 UC patients, with mean ± SD ages of 43.3 ± 12.6 and 44.9 ± 16.5 years, respectively. The most frequent drug classes at index were biologics for CD (62.7%) and 5-aminosalicylate derivates for UC patients (91.7%). During follow-up, 65.3% of CD and 86.1% of UC patients initiated a new treatment at least once. Discontinuations/dose changes occurred in 68.1% of CD patients [median 2.0 (IQR: 2-5)] and 94.3% of UC patients [median 4.0 (IQR: 3-7)]. On average, CD and UC patients had 4.4 ± 2.6 and 5.0 ± 3.3 outpatient visits, respectively. The median time to first mild or no activity was 319 (IQR: 239-358) d for CD and 320 (IQR: 288-358) d for UC patients. At 9-12 mo, 22.0% of CD and 20.0% of UC patients had active disease. CONCLUSION: Although a marked proportion of active IBD patients achieved disease control within one year, the considerable time to achieve this outcome represents an unmet medical need of the current standard of care in a Brazilian real-world setting.

ABSTRACT

CONTEXT: Glutamine supplementation has been applied clinical practice to treat inflammatory bowel disease (IBD). However, scientific evidence about this is still controversial. OBJECTIVE: In this review, we systematically evaluated the effects of glutamine supplementation on IBD, based on evidence from randomized clinical trials. DATA SOURCE: This review was conducted in accordance with the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). We used the PubMed and SciVerse Scopus databases. The Cochrane collaboration tool was used to assess the risk of bias in clinical trials. DATA EXTRACTION: The review was carried out by two independent researchers according to the established inclusion criteria. The PICO (patient, intervention, comparison, and outcomes) strategy was used, with the descriptors: "glutamine," "supplementation," "inflammatory bowel diseases," "Crohn's disease," and "ulcerative colitis". DATA SYNTHESIS: Seven research articles were selected for this systematic review. In these studies, glutamine was administered to the participants through oral (21-30g or 0.5g per kg of participant's body weight), enteral (7.87g-8.3 g/100g of the enteral formula), and/or parenteral (0.3  g/kg of the participant's body weight) routes. No changes in anthropometry or biochemical parameters were observed. However, in one study reduced intestinal permeability and morphometry were reported. In two other studies, a slight effect of glutamine on inflammation and oxidative stress was observed. Additionally, two other studies reported an effect of glutamine supplementation on disease activity. CONCLUSIONS: The findings obtained through this systematic review indicate that glutamine supplementation has no effect on disease course, anthropometric measurements, intestinal permeability and morphology, disease activity, intestinal symptoms, biochemical parameters, oxidative stress and inflammation markers in patients with IBD, regardless of the route of administration, either treated at a hospital or as outpatients.

ABSTRACT

OBJECTIVE: To gather scientific evidence on the role of diet in inflammatory bowel diseases. METHODS: Integrative review with studies published in the last 10 years in national and international journals. Original studies developed with adult human beings aged ≥18 years were included and articles published before 2010, literature reviews, and those that did not focus on elements that answered the guiding question were excluded. RESULTS: 14 articles were selected that addressed important dietary elements in inflammatory bowel disease such as fermentable carbohydrates and polyols, foods of animal origin, foods rich in omega 3, consumption of fruits and vegetables, use of probiotic supplements, whey proteins and soy. CONCLUSION: The diet, as a potentially modifiable environmental factor, plays an important role in the prevention and treatment of inflammatory bowel diseases. The reduction in the consumption of fermentable carbohydrates and polyols combined with the increase in the consumption of fruits and vegetables as well as the exclusion of products of animal origin such as beef, pork, milk and eggs can help control inflammation and improve the quality of life of patients with inflammatory bowel diseases. The use of probiotics increases food tolerance and, whey and soy proteins, can alter body composition and reduce inflammation.

ABSTRACT

Fibrosis is considered a complex form of tissue damage commonly present in the end stage of many diseases. It is also related to a high percentage of death, whose predominant characteristics are an excessive and abnormal deposition of fibroblasts and myofibroblasts -derived extracellular matrix (ECM) components. Epithelial-to-mesenchymal transition (EMT), a process in which epithelial cells gradually change to mesenchymal ones, is a major contributor in the pathogenesis of fibrosis. The key mediator of EMT is a multifunctional cytokine called transforming growth factor-ß (TGF-ß) that acts as the main inducer of the ECM assembly and remodeling through the phosphorylation of Smad2/3, which ultimately forms a complex with Smad4 and translocates into the nucleus. On the other hand, the bone morphogenic protein-7 (BMP-7), a member of the TGF family, reverses EMT by directly counteracting TGF-ß induced Smad-dependent cell signaling. NLRP3 (NACHT, LRR, and PYD domains-containing protein 3), in turn, acts as cytosolic sensors of microbial and self-derived molecules and forms an immune complex called inflammasome in the context of inflammatory commitments. NLRP3 inflammasome assembly is triggered by extracellular ATP, reactive oxygen species (ROS), potassium efflux, calcium misbalance, and lysosome disruption. Due to its involvement in multiple diseases, NLRP3 has become one of the most studied pattern-recognition receptors (PRRs). Nevertheless, the role of NLRP3 in fibrosis development has not been completely elucidated. In this review, we described the relation of the previously mentioned fibrosis pathway with the NLRP3 inflammasome complex formation, especially EMT-related pathways. For now, it is suggested that the EMT happens independently from the oligomerization of the whole inflammasome complex, requiring just the presence of the NLRP3 receptor and the ASC protein to trigger the EMT events, and we will present different pieces of research that give controversial point of views.

ABSTRACT

Ulcerative colitis is an inflammatory bowel disease that affects the mucous membrane of the colon. The pathogenesis is not clear, but there is evidence of a complex interaction between genetic, environmental, and immunological factors. In this regard, we highlight the role of zinc in the immune system and probable control of the disease. This study evaluated the effect of zinc supplementation on the inflammatory response in patients with ulcerative colitis. A blind interventional study involving 41 patients of both sexes, who underwent either zinc gluconate supplementation (n = 23), or treatment with a placebo (corn starch) (n = 18). Patients were evaluated for dietary zinc intake, plasma and erythrocyte zinc concentrations, and serum levels of Th1/Th2/Th17 type cytokines at baseline (T0) and 30 (T1) and 60 (T2) days after intervention. Patients in the zinc supplementation group had a lower probability of having an adequate zinc intake than placebo. In this same group, there was a significant difference between plasma zinc concentrations (T1 in relation to T0, T2 in relation to T1, and T2 in relation to T0) and erythrocyte zinc (T1 in relation to T0 and T2 in relation to T1). Zinc supplementation resulted in significant changes in the concentrations of IL-2 and IL-10 without differences in the other interleukins. Zinc gluconate intervention in patients with ulcerative colitis improves the nutritional status of this mineral in these patients and positively influences their clinical outcome, reinforcing the role of zinc as an important dietary component in disease control.

ABSTRACT

Resumo Objetivo Verificar o conhecimento do familiar cuidador frente ao paciente com demência e avaliar a sobrecarga proveniente do cuidado. Método Trata-se de pesquisa qualitativa, desenvolvida no ambulatório de um hospital de referência em neurologia na cidade do Recife, PE, Brasil. Os dados foram coletados por meio da entrevista semiestruturada, questionário sociodemográfico e da aplicação da Escala de Zarit, os dados foram tratados pela análise de conteúdo proposta por Bardin e discutidos de acordo com os constructos da problematização e autonomia de Paulo Freire. Os participantes assinaram o TCLE atestando o consentimento para a pesquisa Resultados Da análise das entrevistas com 17 familiares cuidadores, emergiram três categorias temáticas: desconhecimento sobre a doença, percepção do familiar cuidador frente às necessidades do paciente e sobrecarga familiar. Com a progressão da doença, torna-se imprescindível a presença do cuidador, entretanto a maioria não possui suporte necessário para assistir aos seus familiares. Conclusão O estudo verificou o despreparo e a dificuldade do cuidador com manejo de seus familiares que possuem alguma síndrome demencial. Assim, torna-se necessária a continuidade de mais produções sobre essa temática e suas repercussões na vida dos familiares cuidadores, a fim de auxiliar nas estratégias de promoção à saúde para essa população.


Abstract Objective To verify the knowledge of the family caregiver before the patient with dementia, in addition to assessing the burden resulting from care. Method This is a qualitative research, developed at the outpatient clinic of a reference hospital in neurology in the city of Recife, PE, Brasil. The data were collected through a semi-structured interview, a sociodemographic questionnaire and the application of the Zarit Scale and discussed through the content analysis proposed by Bardin and according to the constructs of Paulo Freire's problematization and autonomy. The participants signed the informed consent form attesting the consent for the research Results From the analysis of the interviews with 17 family caregivers, three thematic categories emerged: lack of knowledge about the disease, perception of the family caregiver regarding the patient's needs and family burden. With the progression of the disease, the presence of the caregiver becomes essential, however most do not have the necessary support to assist their family members. Conclusion The study verified the unpreparedness and difficulty of the caregiver in managing his family members who have some dementia syndrome. Thus, it is necessary to continue more productions on this theme and its repercussions on the lives of family caregivers, in order to assist in health promotion strategies for this population.

ABSTRACT

BACKGROUND: Inflammatory bowel diseases (IBD) have been associated with a low quality of life (QoL) and a negative impact on work productivity compared to the general population. Information about disease control, patient-reported outcomes (PROs), treatment patterns and use of healthcare resources is relevant to optimizing IBD management. AIM: To describe QoL and work productivity and activity impairment (WPAI), treatment patterns and use of healthcare resources among IBD patients in Brazil. METHODS: A multicenter cross-sectional study included adult outpatients who were previously diagnosed with moderate to severe Crohn's disease (CD) or ulcerative colitis (UC). At enrolment, active CD and UC were defined as having a Harvey Bradshaw Index ≥ 8 or a CD Activity Index ≥ 220 or calprotectin > 200 µg/g or previous colonoscopy results suggestive of inadequate control (per investigator criteria) and a 9-point partial Mayo score ≥ 5, respectively. The PRO assessment included the QoL questionnaires SF-36 and EQ-5D-5L, the Inflammatory Bowel Disease Questionnaire (IBDQ), and the WPAI questionnaire. Information about healthcare resources and treatment during the previous 3 years was collected from medical records. Chi-square, Fisher's exact and Student's t-/Mann-Whitney U tests were used to compare PROs, treatment patterns and the use of healthcare resources by disease activity (α = 0.05). RESULTS: Of the 407 patients in this study (CD/UC: 64.9%/35.1%, mean age 42.9/45.9 years, 54.2%/56.6% female, 38.3%/37.1% employed), 44.7%/25.2% presented moderate-to-severe CD/UC activity, respectively, at baseline. Expressed in median values for CD/UC, respectively, the SF-36 physical component was 46.6/44.7 and the mental component was 45.2/44.2, the EQ-visual analog scale score was 80.0/70.0, and the IBDQ overall score was 164.0/165.0. Moderate to severe activity, female gender, being unemployed, a lower educational level and lower income were associated with lower QoL (P < 0.05). Median work productivity impairment was 20% and 5% for CD and UC patients, respectively, and activity impairment was 30%, the latter being higher among patients with moderate to severe disease activity compared to patients with mild or no disease activity (75.0% vs 10.0%, P < 0.001). For CD/UC patients, respectively, 25.4%/2.8% had at least one surgery, 38.3%/19.6% were hospitalized, and 70.7%/77.6% changed IBD treatment at least once during the last 3 years. The most common treatments at baseline were biologics (75.3%) and immunosuppressants (70.9%) for CD patients and 5-ASA compounds (77.5%) for UC patients. CONCLUSION: Moderate to severe IBD activity, especially among CD patients, is associated with a substantial impact on QoL, work productivity impairment and an increased number of IBD surgeries and hospitalizations in Brazil.

ABSTRACT

Abstract Background The Brief Negative Symptom Scale (BNSS) assesses the presence and intensity of negative symptoms in schizophrenia. Objectives This study aimed to carry out the BNSS cross-cultural adaptation to the Brazilian Portuguese language and verify its content validity and reliability. Methods This is a methodological study that followed these steps: (1) implementation of the cross-cultural adaptation and translation protocol, (2) BNSS adapted content validation, and (3) reliability assessment. Six experts participated in the adaptation process. The sample consisted of 30 individuals diagnosed with schizophrenia and assisted at the Brazilian Psychosocial Care Center (CAPS), in João Pessoa, Paraíba, Brazil, which was the research setting. Results The cross-cultural adaptation was successful due to the values obtained for each aspect evaluated, such as semantic (0.922), idiomatic (0.910), experiential (0.961), and conceptual equivalence (0.974). The same happened with content validity regarding clarity of language (0.935), practical relevance (0.974), and theoretical relevance (0.948). Cronbach's alpha coefficient was 0.884 for the entire instrument, and the items ranged from 0.865 to 0.882. Discussion The BNSS adaptation process has shown to be satisfactory for use in the Brazilian context, constituting a useful clinical tool for teaching and research.

ABSTRACT

BACKGROUND: The Pain Medication Questionnaire (PMQ) assesses the risk of opioid abuse in people with non-oncological chronic pain. METHODS: This is a methodological study conducted at a hemotherapy centre in Recife, Pernambuco state, Brazil. A Cross-cultural adaptation was carried out by a committee of nine specialists, and we applied the PMQ to a pre-final sample of 40 individuals with sickle cell anemia, in addition to a sociodemographic and clinical questionnaire. RESULTS: The mean agreement indexes for PMQ equivalences were the following: semantic (0.996), idiomatic (0.970), experiential (0.991), conceptual (0.953), language clarity (0.991), practical relevance (0.906), and theoretical relevance (0.945). Assessment of the PMQ showed that 50% of participants obtained a score equivalent to medium risk of opioid abuse. Cronbach's alpha coefficient for the adapted PMQ instrument was 0.705, ranging from 0.641 to 0.736 among its items. CONCLUSION: The cross-cultural adaptation of the Pain Medication Questionnaire was satisfactory and easy to apply in the Brazilian population. It is clinically relevant, contributing professional practice and enlightening patients with sickle cell anemia on their behavioral dynamics with respect to opioid consumption. It will also contribute to teaching and research, because it is a useful tool for investigating the risk of abusive behavior in people with chronic pain.

ABSTRACT

INTRODUCTION: Depression is a common debilitating disease that affects individuals in all age groups. The impact of the diagnosis extends beyond the individual, with negative effects on mental health, physical health and social well-being. Self-efficacy has been referenced as an important aspect to the prognosis of mood disorders by conferring co-responsibility to the affected individual to face his/her health problems. Several assessment tools are found in the literature for measuring self-efficacy, but it is not yet clear which of these measures are more applicable to individuals with mood disorders, particularly depression. Thus, the aim of present study is to propose a systematic review to examine the psychometric properties and applicability of assessment tools designed to measure self-efficacy in individuals with symptoms and/or a diagnosis of depression. METHODS AND ANALYSIS: This protocol is reported in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols statement and the review will be reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. The evaluation of the psychometric properties of the health outcome measures will be conducted according to COSMIN guidelines. Two independent reviewers will perform the electronic searches in the PubMed, Web of Science, PsycInfo, SCOPUS and CINAHL databases, followed by the use of the 'snowball' strategy. The inclusion criteria will be (1) instrument validation studies, (2) developed with individuals of any age (3) with symptoms or a diagnosis of depression. Two independent reviewers will analyse the titles and abstracts of the articles retrieved during the search for pre-selection, followed by full-text analyses to determine inclusion in the review based on the eligibility criteria. Cases of a divergence of opinion will be resolved by a third reviewer. Descriptive analysis of the articles will be performed (data on participants, characteristics, psychometric properties and clinical usefulness of the assessment tools). ETHICS AND DISSEMINATION: The proposed systematic review will provide information on assessment tools employed to measure self-efficacy with regard to coping with depression, offering data on the psychometric properties, strong and weak points, and clinical applicability. As a secondary analysis of the literature, the approval of an ethics committee is not required. PROSPERO REGISTRATION NUMBER: CRD42017078707.

ABSTRACT

INTRODUCTION: Opioid use patterns of individuals with non-cancer pain are influenced by the behavioural dynamics of the individual in managing and properly following the prescription. The use of assessment tools for measuring the risk of behaviour suggestive of opioid abuse is important for health professionals who provide care to individuals with non-cancer pain. The aim of the proposed review is to analyse the psychometric properties of tools for measuring the risk of behaviour suggestive of opioid abuse in adults with non-cancer pain. METHODS AND ANALYSIS: The review process will be based on the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. The Consensus-Based Standards for the Selection of Health Measurement Instruments will be used to analyse the assessment tools. Two independent reviewers will perform the literature search and analysis procedures. Searches will be performed on PubMed, Web of Science, Cochrane, Scopus, and Cumulative Index to Nursing and Allied Health Literature databases, and the 'snowball' strategy will be employed. The inclusion criteria will be (1) validation studies, (2) assessment tools designed exclusively for measuring the risk of behaviour suggestive of opioid abuse and (3) assessment tools designed for evaluation of adults with chronic non-cancer pain. The titles and abstracts of the studies retrieved from the databases will be analysed for the preselection of articles, which will be submitted to a full-text analysis to define the final sample. Divergence of opinion between two reviewers will be resolved by consulting a third reviewer. ETHICS AND DISSEMINATION: The review will offer an overview of assessment tools available for measuring the risk of behaviour suggestive of opioid abuse, which is relevant to reducing the risk of deaths due to abusive consumption and for clinical management of adults with chronic non-cancer pain.
