RESUMEN

OBJECTIVE: In the Brazilian public national healthcare system, botulinum toxin type A has traditionally been the sole treatment option for patients with dystonia. However, as of October 2022, Deep Brain Stimulation (DBS) garnered positive recommendations for the condition. This study aims to assess the cost-effectiveness of DBS in treating adults with generalized and cervical dystonia within the Brazilian healthcare context, considering its recent inclusion. METHODS: A systematic review identified randomized controlled trials (RCTs) assessing DBS efficacy in treating adults with generalized and cervical dystonia. Two cost-utility analyses compared the cost-effectiveness of DBS plus the Best Clinical Practice (BCP) to BCP alone. Markov models, which included three health states (no clinical improvement, clinical improvement, and death), employed a one-year cycle and a lifetime horizon. The study utilized both one-way and probabilistic sensitivity analyses. RESULTS: Two RCTs, one for each condition, revealed superior clinical improvement with DBS when compared to sham simulation. The Incremental Cost-Utility Ratio (ICUR) was $ 1,121.66 for generalized dystonia and $4,556.50 for cervical dystonia. Effectiveness discount rates and age at surgery were identified as influential parameters. In 1,000 Monte Carlo simulations, 99.9% of the ICUR values for generalized dystonia and 74.2 % for cervical dystonia fell below the cost-effectiveness threshold in Brazil ($8,146.64 per QALY). CONCLUSIONS: From the perspective of the Brazilian public health system, the combination of DBS and BCP appears to be cost-effective for the treatment of both generalized and cervical dystonia when compared to BCP alone.

RESUMEN

We aimed to study the influence of preventing methemoglobin (metHb) formation, in the roles of peroxiredoxin 2 (Prx2), glutathione peroxidase (GPx) and catalase (CAT) on the erythrocyte antioxidant defense system. We performed in vitro assays using healthy erythrocytes, with and without inhibition of autoxidation of Hb (saturation with carbon monoxide), followed by H2O2-induced oxidative stress. We assessed the enzyme activities and amounts of CAT, GPx and Prx2 in the red blood cell (RBC) cytosol and membrane and several biomarkers of oxidative stress, such as the reduced and oxidized glutathione levels, thiobarbituric acid reactive substances (TBARS) levels, membrane bound hemoglobin and total antioxidant status. When autoxidation of Hb was inhibited, no significant changes were found for GPx and CAT; Prx2 was observed only in the monomeric form in the cytosol and none bound to the membrane. Blocking the function of Hb as a pseudo-peroxidase does not seem to have an impact on the function of the RBC peroxidases.

RESUMEN

OBJECTIVE: Verify whether Hypervigilance to Pain (HP) and Sleep Quality (SQ) are confounding variables in the infrared thermography (IT) examination of the temporomandibular joint and temporal and masseter muscles. MATERIALS AND METHODS: A cross-sectional and analytical study was conducted, collecting HP and SQ data from 80 participants without Temporomandibular Disorders (TMD), performing their IT and another 40 participants with TMD. For the selection of participants with and without TMD, the TMD Pain Screener questionnaire and axis I of the Diagnostic Criteria for Temporomandibular Disorders were applied. SQ was verified using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. For the HP assessment the Pain Vigilance and Awareness Questionnaire (PVAQ) was applied. And the IT was performed through a FLIR infrared sensor camera, model T650 Infrared. RESULTS: No significant correlations were found between SQ and the temperatures of the areas of interest (p > 0.05), and regarding HP, a statistically significant positive correlation was found with the dimensionless (ρ = 0.289) and non-dimensionless (ρ = 0.223) asymmetries of temporal muscle temperatures. In the temperature comparisons between the participants without TMD and the participants with TMD, significant differences were found (p < 0.05), also when the group without TMD was controlled according to both HP and SQ (p < 0.05), with higher temperatures found in the TMD group. CONCLUSION: HP and SQ can be considered confounding variables in infrared thermography examination of the temporomandibular region.

RESUMEN

Cannabis sativa is a plant of the Cannabaceae family, whose molecular composition is known for its vast pharmacological properties. Cannabinoids are the molecules responsible for Cannabis sativa potential effects, especially tetrahydrocannabinol and cannabidiol. Scientific development has shown interest in the potential of cannabidiol in various health conditions, as it has demonstrated lower adverse events and great pharmacological potential, especially when administered topically. The present study aims to carry out a scoping review, focusing on the use of cannabidiol, in vivo models, for topical administration. Thus, the methodological approach used by the Joanna Briggs Institute was applied, and the studies were selected based on previously established inclusion criteria. Even though more information regarding the dose to achieve pharmacological potential is still needed, cannabidiol demonstrated potential in treating and preventing different conditions, such as glaucoma, atopic dermatitis, epidermolysis bullosa, and pyoderma gangrenosum.

RESUMEN

Catalase (CAT), glutathione peroxidase (GPx), and peroxiredoxin 2 (Prx2) can counteract the deleterious effects of oxidative stress (OS). Their binding to the red blood cell (RBC) membrane has been reported in non-immune hemolytic anemias (NIHAs). Our aim was to evaluate the relationships between CAT, GPx, and Prx2, focusing on their role at the RBC membrane, in hereditary spherocytosis (HS), sickle cell disease (SCD), ß-thalassemia (ß-thal), and healthy individuals. The studies were performed in plasma and in the RBC cytosol and membrane, evaluating OS biomarkers and the enzymatic activities and/or the amounts of CAT, GPx, and Prx2. The binding of the enzymes to the membrane appears to be the primary protective mechanism against oxidative membrane injuries in healthy RBCs. In HS (unsplenectomized) and ß-thal, translocation from the cytosol to the membrane of CAT and Prx2, respectively, was observed, probably to counteract lipid peroxidation. RBCs from splenectomized HS patients showed the highest membrane-bound hemoglobin, CAT, and GPx amounts in the membrane. SCD patients presented the lowest amount of enzyme linkage, possibly due to structural changes induced by sickle hemoglobin. The OS-induced changes and antioxidant response were different between the studied NIHAs and may contribute to the different clinical patterns in these patients.

RESUMEN

The aim of this study was to assess, through a systematic review, the status of infrared thermography (IRT) as a diagnostic tool for skin neoplasms of the head and neck region and in order to validate its effectiveness in differentiating benign and malignant lesions. A search was carried out in the LILACS, PubMed/MEDLINE, SCOPUS, Web of Science and EMBASE databases including studies published between 2004 and 2024, written in the Latin-Roman alphabet. Accuracy studies with patients aged 18 years or over presenting benign and malignant lesions in the head and neck region that evaluated the performance of IRT in differentiating these lesions were included. Lesions of mesenchymal origin and studies that did not mention histopathological diagnosis were excluded. The systematic review protocol was registered in the PROSPERO database (CRD42023416079). Reviewers independently analyzed titles, abstracts, and full-texts. After extracting data, the risk of bias of the selected studies was assessed using the QUADAS - 2 tool. Results were narratively synthesized and the certainty of evidence was measured using the GRADE approach. The search resulted in 1,587 records and three studies were included. Only one of the assessed studies used static IRT, while the other two studies used cold thermal stress. All studies had an uncertain risk of bias. In general, studies have shown wide variation in the accuracy of IRT for differentiating between malignant and benign lesions, with a low level of certainty in the evidence for both specificity and sensitivity.

RESUMEN

OBJECTIVES: To assess the influence of two conventional and one adapted cheek and lip retractors and three emissivity setting values on intraoral infrared thermography (IT) temperature values. METHODS: The sample was composed by 50 volunteers. Three cheek and lip retractors were tested: Group 1-flex retractor (FR); Group 2-FR adapted with Styrofoam; Group 3-U-type retractor (UR) for cheek and lip. All thermograms were acquired using FLIR T650 infrared camera. A set of three thermograms in frontal norm were acquired for each lip and cheek retractor at 0.91, 0.96, and 0.98ε, with an interval of 15 min between each set of images to avoid thermal interference. All images were assessed by two observers. The ROIs' mean temperature of the four upper incisors was recorded. Two-way ANOVA and Sidak post-test were used for data assessment with a significance level of 5%. RESULTS: Group 3 showed higher mean temperature than Groups 1 and 2 at all emissivity settings for all assessed teeth (P < .05). 0.91ε showed higher temperature than 0.96ε and 0.98ε for all assessed variables (P < .01). Contralateral teeth assessed using Group 3 at 0.91ε showed statistical differences between each other (P < .05). No statistical difference was observed between contralateral teeth assessed using Groups 1 and 2 at 0.96ε and 0.98ε (P > .05). CONCLUSIONS: The choice of cheek and lip retractor and emissivity setting can interfere on intraoral IT temperature values. U-type cheek and lip retractor and 0.91ε setting should not be used for IT image acquisition when assessing dental tissues.

RESUMEN

Purpose: Pycnodysostosis (PYCD), an autosomal recessive syndrome, is characterized by an imbalance in bone remodeling that produces various clinical and radiographic craniofacial manifestations. This review represents a systematic examination of these manifestations, as well as oral features associated with PYCD. Materials and Methods: A systematic review was conducted across 8 databases from February to March 2023. The search strategy focused on studies reporting cases of PYCD that examined the clinical and radiographic craniofacial and oral characteristics associated with this syndrome. Results: The review included 84 studies, encompassing a total of 179 cases of PYCD. More than half of the patients were female (55.3%), and the mean age was 14.7 years. Parental consanguinity was reported in 51.4% of the cases. The most common craniofacial clinical manifestation was a prominent nose, observed in 57.5% of cases. Radiographically, the most frequently reported craniofacial characteristics included the presence of an obtuse mandibular angle (84.3%) and frontal cranial bosses (82.1%). Clinical and radiographic examinations revealed oral alterations, with micrognathia present in 62.6% of patients and malocclusion in 59.2%. Among dental anomalies, tooth agenesis was the most commonly reported, affecting 15.6% of patients. Conclusion: Understanding the clinical and radiographic craniofacial features of PYCD is crucial for dental professionals. This knowledge enables these clinicians to devise effective treatment plans and improve patient quality of life.

RESUMEN

Background: The purpose of this study was to assess the external root surface thermal behavior when submitted to three different obturation techniques. Material and Methods: Forty-five single-rooted premolars were selected, prepared and randomly divided into three groups according to the studied obturation techniques: lateral condensation (LC), single cone technique (SCT) and injectable thermoplasticized technique (IT). Each tooth was placed in a customized apparatus and connected to a thermocouple. A FLIR T650sc infrared thermal camera was used to assess root temperature in a room under controlled temperature and humidity. Temperature values were recorded using the thermal camera and thermocouples before, during and 30, 60, 90, 120, 150s after obturation. Shapiro-Wilk, QQ-plot, Levene's, ANOVA-three-way, Mauchly's sphericity, Box's M and Bonferroni tests were used to assess data. The significance level was set at 5%. Results: Infrared assessment showed significant temperature changes between time intervals, obturation techniques and root thirds. Temperature increase was observed 30s after obturation for STL, LC and IT, followed by a gradual temperature decline, with temperature values similar to the initial temperature at 150s for LC and IT. SCT temperature values only returned to normal 60s after obturation in the apical third and 90s in the middle and cervical thirds. In all techniques, the temperature did not rise above the critical limit of 10°C. Conclusions: All studied obturation techniques increased root surface temperature with IT showing the highest temperature increase. However, the temperature increase does not exceed the acceptable limits, not causing damage to the surrounding tissues. Key words:Endodontics, changes in body temperature, root canal filling, thermography.

RESUMEN

The antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and peroxiredoxin 2 (Prx2) are particularly important in erythroid cells. Reticulocytes and other erythroid precursors may adapt their biosynthetic mechanisms to cell defects or to changes in the bone marrow environment. Our aim was to perform a comparative study of the mRNA levels of CAT, GPX1, PRDX2 and SOD1 in reticulocytes from healthy individuals and from patients with hereditary spherocytosis (HS), sickle cell disease (SCD) and ß-thalassemia (ß-thal), and to study the association between their transcript levels and the reticulocyte maturity indices. In controls, the enzyme mRNA levels were significantly correlated with reticulocyte maturity indices for all genes except for SOD1. HS, SCD and ß-thal patients showed younger reticulocytes, with higher transcript levels of all enzymes, although with different patterns. ß-thal and HS showed similar reticulocyte maturity, with different enzyme mRNA levels; SCD and HS, with different reticulocyte maturity, presented similar enzyme mRNA levels. Our data suggest that the transcript profile for these antioxidant enzymes is not entirely related to reticulocyte maturity; it appears to also reflect adaptive mechanisms to abnormal erythropoiesis and/or to altered erythropoietic environments, leading to reticulocytes with distinct antioxidant potential according to each anemia.

RESUMEN

Purpose: This study assessed the intensity of artifacts produced by 2 metal posts, 2 cements, and different exposure parameters using 2 cone-beam computed tomography (CBCT) units. Materials and Methods: The sample was composed of 20 single-rooted premolars, divided into 4 groups: Ni-Cr/zinc phosphate, Ni-Cr/resin cement, Ag-Pd/zinc phosphate, and Ag-Pd/resin cement. Samples were scanned before and after post insertion and cementation using a CS9000 3D scanner with 4 exposure parameters (85/90 kV and 6.3/10 mA) and an i-CAT scanner with 120 kV and 5 mA. The presence of artifacts was assessed subjectively by 2 observers and objectively by a trained observer using ImageJ software. The Mann-Whitney, Wilcoxon, weighted kappa, and chi-square tests were used to assess data at a 95% confidence level (α<0.05). Results: In the subjective analyses, AgPd presented more hypodense and hyperdense lines than NiCr (P<0.05), and more hypodense halos were found using i-CAT (P<0.05) than using CS9000 3D. More hypodense halos, hypodense lines, and hyperdense lines were observed at 10 mA than at 6.3 mA (P<0.05). More hypodense halos were observed at 85 kV than at 90 kV (P<0.05). CS9000 3D presented more hypodense and hyperdense lines than i-CAT (P<0.05). In the objective analyses, AgPd presented higher percentages of hyperdense and hypodense artifacts than NiCr (P<0.05). Zinc phosphate cement presented higher hyperdense artifact percentages on CS9000 3D scans (P<0.05). CS9000 3D presented higher artifact percentages than i-CAT (P<0.05). Conclusion: High-atomic-number alloys, higher tube current, and lower tube voltage may increase the artifacts present in CBCT images.

RESUMEN

PURPOSE: Third molar extraction can cause surgical trauma, which is associated with pain, edema, trismus, and functional limitations. The aim of the present systematic review was to investigate the effects of photobiomodulation (PBM) following the extraction of impacted mandibular third molars. METHODS: An electronic search was conducted in 10 databases from inception up to October 2021 and the grey literature, with no restrictions regarding language or year of publication. Randomized controlled clinical trials (RCT) were included. Studies that were not RCTs were excluded. Reviewers independently analyzed titles and abstracts, followed by full-text analysis. This systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The exposure variable was the use of PBM and the outcomes were pain, edema, and trismus. Meta-analysis was performed using a random-effects model. The estimate was calculated considering standardized mean differences (SMD) and respective 95% confidence intervals (CI) obtained for each outcome on the first, second, third and seventh postoperative days. The level of evidence was assessed using the GRADE approach. RESULTS: The search resulted in the 3,324 records. Thirty-three RCTs were included in the systematic review and 23 of these were included in the meta-analyses. The studies involved a total of 1,347 participants (56.6% female and 43.4% male) between 16 and 44 years of age. A greater reduction in pain was found in the PBM group compared to the control group on the third postoperative day (SMD: -1.09; 95% CI: -1.63; -0.55; P < .001; low certainty). Edema was discretely lower in the PBM group on the second postoperative day (SMD: -0.61; 95% CI: -1.09; -0.13; P < .001; low certainty) and trismus was discretely lower in the PBM group on the seventh postoperative day (SMD: 0.48; 95% CI: 0.00; 0.96; P < .001; very low certainty). CONCLUSION: The evidence of the effect of PBM regarding the control of pain, edema, and trismus following third molar extractions is low or very low.

RESUMEN

OBJECTIVES: Analyze the diagnostic and prognostic value of the sFlt-1/PlGF ratio in pregnant women with at least one sign/symptom of suspected/diagnosed pre-eclampsia. METHODS: This retrospective observational study included 170 pregnant women with at least one sign/symptom of pre-eclampsia, who had sFlt-1/PlGF ratio values. The following information was evaluated: pregnant women's demographic data and clinical history; laboratory data (urine protein/creatinine ratio; sFlt-1/PlGF ratio); signs and symptoms presented; clinical outcome; fetal complications; data related to childbirth. Statistical analysis was performed by R Software Version 3.5.2. RESULTS: Among the 170 patients, 78 presented pre-eclampsia. The median sFlt-1/PlGF ratio was significantly higher [143.1 (2.2-2,927.1)] for women who presented pre-eclampsia than for women without pre-eclampsia [33.5 (0.8-400.2)]. The negative predictive value of sFlt-1/PlGF ratio <38 was 83.9 % (95 % CI, 71.7-92.4 %) and the positive predictive value of sFlt-1/PlGF ratio >85 or 110 (for late onset pre-eclampsia) was 76.4 % (95 % CI, 66.2-84.8 %). sFlt-1/PlGF >85 or 110 was associated with pre-eclampsia clinical development, fetal complications, shorter gestational age at birth, higher number of caesarean deliveries and lower birth weight. CONCLUSIONS: The sFlt-1/PlGF ratio, together with the standard diagnostic criteria, can be used to rule out pre-eclampsia, identify high-risk patients and predict the occurrence of adverse outcomes.

RESUMEN

OBJECTIVES: This study aimed to assess and compare age estimation on panoramic radiography using the Kvaal method and machine learning (ML). METHODS AND MATERIALS: 554 panoramic radiographs were selected from a Brazilian practice. To estimate age using the Kvaal method, the following measurements were performed on the upper left central incisors and canines: tooth, pulp and root length; root and pulp width at three different levels: at the enamel-cementum junction (ECJ); midpoint between the enamel-cementum junction and; at the mid root level. For ML age estimation, radiomic, semantic and the radiomic-semantic attribute extractions were assessed. Nineteen semantic and 14 radiomic attributes and a single set of 33 semantic-radiomic attributes were extracted. Logistic Regression, Linear Regression, KNN, SVR, Decision Tree Reg, Random Forest Reg, Gradient Boost Reg e XG Boosting Reg were used for ML classification. For the Kvaal method, Mann-Whitney test, Spearman correlation coefficient, Student's t-test and linear regression with its respective coefficient of determination were used to estimate age and to assess data variability. RESULTS: Mean absolute error (MAE) and standard error estimate (SEE) were assessed. For the Kvaal method, upper incisors presented higher precision than canines (R²: 0.335, SSE: 7.108). Males presented better MAE and SEE values (5.29,6.96) than females (5.69,7.37). The radiomic-semantic attributes presented superior precision (MAE: 4.77) than the radiomic and semantic (MAE: 5.23) attributes. The XG Boosting Reg classifier performed better than the other six assessed classifiers (MAE: 4.65). ML (MAE: 4.77 presented higher age estimation precision than the Kvaal method (MAE: 5.68). CONCLUSION: The use of ML on panoramic radiographs can improve age estimation.

RESUMEN

OBJECTIVE: The objective of this study was to assess the quality of clinical practice guidelines (CPGs) for the pharmacological treatment of depression along with their recommendations and factors associated with higher quality. DESIGN: We conducted a systematic review that included CPGs for the pharmacological treatment of depression in adults. DATA SOURCES: We searched for publications from 1 January 2011 to 31 December 2021, in MEDLINE, Cochrane Library, Embase, PsycINFO, BVS and 12 other databases and guideline repositories. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: We included CPGs containing recommendations for the pharmacological treatment of depression in adults at outpatient care setting, regardless of whether it met the U.S. National Academy of Medicine criteria, or not. If a CPG included recommendations for both children and adults, they were considered. No language restriction was applied. DATA EXTRACTION AND SYNTHESIS: Data extraction was also conducted independently and in duplicate, a process that was validated in a previous project. The quality of the CPGs and their recommendations were assessed by three independent reviewers using Appraisal of Guidelines for Research and Evaluation (AGREE II) and Appraisal of Guidelines for Research and Evaluation-Recommendations Excellence (AGREE-REX). A CPG was considered to be of high quality if AGREE II Domain 3 was ≥60%; while their recommendations were considered high if AGREE-REX Domain 1 was ≥60%. RESULTS: Seventeen out of 63 (27%) CPGs were classified as high quality, while 7 (11.1%) had high-quality recommendations. The factors associated with higher-scoring CPGs and recommendations in the multiple linear regression analyses were 'Handling of conflicts of interest', 'Multiprofessional team' and 'Type of institution'. 'Inclusion of patient representative in the team' was also associated with higher-quality recommendations. CONCLUSIONS: The involvement of professionals from diverse backgrounds, the handling of conflicts of interest, and the inclusion of patients' perspectives should be prioritised by developers aiming for high-quality CPGs for the treatment of depression.

RESUMEN

Catalase (CAT), glutathione peroxidase (GPx) and Prx2 (peroxiredoxin 2) are the main antioxidant enzymatic defenses of erythrocytes. They prevent and minimize oxidative injuries in red blood cell (RBC) components, which are continuously exposed to oxidative stress (OS). The crosstalk between CAT, GPx and Prx2 is still not fully disclosed, as well as why these typically cytoplasmic enzymes bind to the RBC membrane. Our aim was to understand the interplay between CAT, GPx and Prx2 in the erythrocyte's cytosol and membrane. Under specific (partial) inhibition of each enzyme and increasing H2O2-induced OS conditions, we evaluated the enzyme activities and amounts, the binding of CAT, GPx and Prx2 to RBC membrane, and biomarkers of OS, such as the reduced and oxidized glutathione levels, thiobarbituric acid reactive substances (TBARS) levels, membrane bound hemoglobin and total antioxidant status. Our results support the hypothesis that when high levels of H2O2 get within the erythrocyte, CAT is the main player in the antioxidant protection of the cell, while Prx2 and GPx have a less striking role. Moreover, we found that CAT, appears to have more importance in the antioxidant protection of cytoplasm than of the membrane components, since when the activity of CAT is disturbed, GPx and Prx2 are both activated in the cytosol and mobilized to the membrane. In more severe OS conditions, the antioxidant activity of GPx is more significant at the membrane, as we found that GPx moves from the cytosol to the membrane, probably to protect it from lipid peroxidation.

After reading the 3350 abstracts available, the 320 registered by nurses were selected to make up the sample. Descriptive analysis was performed in the software R. Results: Studies registered between 2010 and 2019 were found, of which 49.7% were in the Southeast region, 49.3% registered by doctors, 46.3% affiliated to federal universities. The most studied nursing area (18.8%) it was adult health, 72.9% had two arms, 53.1% with completed recruitment, 50.3% performed blinding and the most studied type of interventions (21.9%) was the educational. Conclusion: Most intervention studies registered by nurses in the Brazilian Registry of Clinical Trials tested educational interventions in adults, blinded and randomized. (AU)

RESUMEN

Risk-reducing bilateral salpingo-oophorectomy (RRSO) is an effective prophylactic surgery provided to premenopausal women carrying BRCA1 or BRCA2 mutations and presenting an increased risk of developing breast or ovarian cancer. This procedure is related to physiological, sexual, and psychosocial distress, which altogether increase uncertainty and complexity in the clinical decision-making process and post-surgery adaptation. Physician-patient communication (PPC) has been pointed out as a determinant factor in the decision-making to undergo RRSO, and the subsequent adjustment of women. However, studies examining the psychosocial impact of the decision-making process have been scarce and often lack clear theoretical frameworks. While the role of PPC in such processes has been highlighted in a few qualitative studies, there is a paucity of quantitative research addressing this question. Therefore, this narrative review, conducted using a multidisciplinary approach, was planned to: (1) present an updated medical background for RRSO; (2) analyze the psychosocial impact of the decision-making process within a theoretical framework of the Health Belief Model; and (3) discuss the role of PPC in such a decision-making process and in post-surgery. The collected research also enabled the recommendation of some additions to the existing clinical guidelines and the outlining of future research directions.

RESUMEN

INTRODUCTION: Depression is a serious and widespread mental health disorder. A significant proportion of patients with depression fail to remit after two antidepressant treatment trials, a condition named treatment-resistant depression (TRD). Clinical practice guidelines (CPGs) are instruments aimed to improve diagnosis and treatment. This study objective is to systematically appraise the quality and elaborate a comparison of high-quality CPGs with high-quality recommendations aimed at TRD. METHODS AND ANALYSIS: We searched several specialized databases and organizations that develop CPGs. Independent researchers assessed the quality of the CPGs and their recommendations using AGREE II and AGREE-REX instruments, respectively. We selected only high-quality CPGs that included definition and recommendations for TRD. We investigated their divergencies and convergencies as well as weak and strong points. RESULTS: Among seven high-quality CPGs with high-quality recommendations only two (Germany's Nationale Versorgungs Leitlinie-NVL and US Department of Veterans Affairs and Department of Defense-VA/DoD) included specific TRD definition and were selected. We found no convergent therapeutic strategy among these two CPGs. Electroconvulsive therapy is recommended by the NVL but not by the VA/DoD, while repetitive transcranial magnetic stimulation is recommended by the VA/DoD but not by the NVL. While the NVL recommends the use of lithium, and a non-routine use of thyroid or other hormones, psychostimulants, and dopaminergic agents the VA/DoD does not even include these drugs among augmentation strategies. Instead, the VA/DoD recommends ketamine or esketamine as augmentation strategies, while the NVL does not mention these drugs. Other differences between these CPGs include antidepressant combination, psychotherapy as a therapeutic augmentation, and evaluation of the need for hospitalization all of which are only recommended by the NVL. CONCLUSIONS: High-quality CPGs for the treatment of depression diverge regarding the definition and use of the term TRD. There is also no convergent approach to TRD from currently high-quality CPGs.
