RESUMEN

Tracking cell death in vivo can enable a better understanding of the biological mechanisms underlying tissue homeostasis and disease. Unfortunately, existing cell death labeling methods lack compatibility with in vivo applications or suffer from low sensitivity, poor tissue penetration, and limited temporal resolution. Here, we fluorescently labeled dead cells in vivo with Trypan Blue (TBlue) to detect single scattered dead cells or to generate whole-mount three-dimensional maps of large areas of necrotic tissue during organ regeneration. TBlue effectively marked different types of cell death, including necrosis induced by CCl4 intoxication in the liver, necrosis caused by ischemia-reperfusion in the skin, and apoptosis triggered by BAX overexpression in hepatocytes. Moreover, due to its short circulating lifespan in blood, TBlue labeling allowed in vivo "pulse and chase" tracking of two temporally spaced populations of dying hepatocytes in regenerating mouse livers. Additionally, upon treatment with cisplatin, TBlue labeled dead cancer cells in livers with cholangiocarcinoma and dead thymocytes due to chemotherapy-induced toxicity, showcasing its utility in assessing anticancer therapies in preclinical models. Thus, TBlue is a sensitive and selective cell death marker for in vivo applications, facilitating the understanding of the fundamental role of cell death in normal biological processes and its implications in disease.

RESUMEN

OBJECTIVE: To develop a universal system for assessing the speech function in patients with congenital palatal cleft in the postoperative period. MATERIALS AND METHODS: A universal system for assessing the speech function for patients with a palatal cleft can be applied both after the primary operation of uranoplasty and for patients diagnosed with velopharyngeal insufficiency (VPI). The patient's speech is assessed according to the following criteria: defects in the pronunciation of consonants by place of articulation: labial, labiodental, lingual-dental, lingual-palatal, lingual-alveolar; speech breathing; tongue position; directed air stream; voicing disorders; The patient's is also evaluated for the following findings: hypernasality (reflected speech); hypernasality (spontaneous speech); hyponasality; pharyngeal reflex; audible nasal emission/turbulence; facial grimaces; speech intelligibility. The speech therapy and dental assessments are added to obtain a value characterizing the patient's condition: from 0 to 10 scoring indicates than only speech therapy correction is needed; from 11 to 18 - the decision on the necessity of surgical treatment is made by the surgeon together with the speech therapist, from 18 to 25 - surgical treatment is necessary with subsequent sessions with a speech therapist. RESULTS: With the help of this questionnaire, the operating surgeon can more accurately and objectively assess in dynamics the result of the surgical treatment, regardless of the results of speech therapy treatment in the postoperative period. The creation of this scoring system for speech assessment is aimed at objectivizing the results of uranoplasty and speech-improving operations. It allows the surgeon to compare the effectiveness of different surgical methods. CONCLUSION: The universal scoring system for assessing the state of speech function can be applied in the diagnosis of a patient with a palatal cleft both after the primary operation on the palate and after corrective surgical interventions. It allows monitoring progress and identifying dynamics in surgical and speech therapy treatment.

RESUMEN

BACKGROUND: OBQ11 was developed in a Swedish context. To evaluate occupational balance, accurate self-rating instruments in the native language are needed. AIM: The aim was to investigate the measurement properties of the Danish version of OBQ11, using the Rasch analysis. METHOD: Data for the analysis of the Danish version of OBQ11 (OBQ11-DK) was gathered online, and all full data records (n 366) were included in the analysis. RESULTS: Three items showed non-significant marginal under- or overfit, suggesting a degree of misfit between the data and the Rasch model. Unidimensionality was not reached, though, since the proportion of persons with different estimates were more than 5% and thus the OBQ11-DK cannot be said to assess a person's perception of occupational balance. CONCLUSION: The present version of the OBQ11-DK shows the need for further development and testing and is not tested for test/retest or in clinical samples. The results and small number of items may after modifications and further studies make it feasible to implement OBQ11-DK into settings where the measuring of occupational balance is needed.

RESUMEN

Background: Occupational Therapy is among the top interventions for autistic children, hence the need for equitable and effective services in the public and private health and education sectors. Ongoing research into the therapies for autism spectrum disorders in different contexts is also required. Objectives: To explore and describe occupational therapists' assessment and intervention for autistic children in South Africa. Methods: A descriptive qualitative research design using semi-structured interviews to gather data from purposively recruited OTs (n=20). Data were audio-recorded, transcribed and analysed thematically, and compared across three sectors public health, special needs schools and private practice. Results: South African practice across all three sectors was similar to international patterns of informal play-based assessment, sensory processing and Ayres Sensory Integration (ASI®) treatment. Developmental frameworks guided specific approaches. Strong team collaboration was present across sectors, with some transdisciplinary teamwork and co-treatment. Undergraduate and postgraduate training opportunities were, however limited. Conclusions: Occupational therapy assessments had diagnostic value. Informal tools such as developmental checklists were found to have clinical utility, whilst standardised tools were most commonly used to assess sensory processing and visual perception. Recommendations included incorporating ASI® into undergraduate curricula and postgraduate training opportunities with multidisciplinary input to develop ASD professionals in South Africa. It is imperative to advocate for services in under-resourced rural areas and marginalised communities that lack financial and social resources. Occupational therapists need to find new ways of working collaboratively across sectors to ensure effective and comprehensive services in public health and special schools.

RESUMEN

Background: Dysarthria is one of the most frequent communication disorders in patients with Multiple Sclerosis (MS), with an estimated prevalence of around 50%. However, it is unclear if there is a relationship between dysarthria and the severity or duration of the disease. Objective: Describe the speech pattern in MS, correlate with clinical data, and compare with controls. Methods: A group of MS patients (n = 73) matched to healthy controls (n = 37) by sex and age. Individuals with neurological and/or systemic conditions that could interfere with speech were excluded. MS group clinical data were obtained through the analysis of medical records. The speech assessment consisted of auditory-perceptual and speech acoustic analysis, from recording the following speech tasks: phonation and breathing (sustained vowel/a/); prosody (sentences with different intonation patterns) and articulation (diadochokinesis; spontaneous speech; diphthong/iu/repeatedly). Results: In MS, 72.6% of the individuals presented mild dysarthria, with alterations in speech subsystems: phonation, breathing, resonance, and articulation. In the acoustic analysis, individuals with MS were significantly worse than the control group (CG) in the variables: standard deviation of the fundamental frequency (p = 0.001) and maximum phonation time (p = 0.041). In diadochokinesis, individuals with MS had a lower number of syllables, duration, and phonation time, but larger pauses per seconds, and in spontaneous speech, a high number of pauses were evidenced as compared to CG. Correlations were found between phonation time in spontaneous speech and the Expanded Disability Status Scale (EDSS) (r = - 0.238, p = 0.043) and phonation ratio in spontaneous speech and EDSS (r = -0.265, p = 0.023), which indicates a correlation between the number of pauses during spontaneous speech and the severity of the disease. Conclusion: The speech profile in MS patients was mild dysarthria, with a decline in the phonatory, respiratory, resonant, and articulatory subsystems of speech, respectively, in order of prevalence. The increased number of pauses during speech and lower rates of phonation ratio can reflect the severity of MS.

RESUMEN

This study aimed to evaluate sarcopenia and locomotive syndrome in Korean elderly patients, analyze the closely related factors, and determine the threshold for distinguishing participants with sarcopenia, locomotive syndrome, and non-disease. To this end, we enrolled 210 subjects aged 65 years or more and classified them into the sarcopenia (n = 36) and locomotive syndrome (n = 164) groups; a control group was also included (n = 10). We evaluated the characteristics of these patients using the Timed Up and Go (TUG) test and Berg Balance Scale (BBS) and performed statistical analysis. Our findings showed statistically significant differences between the groups, leading to the derivation of a significant threshold value. The threshold value of the TUG test between the control and locomotive syndrome groups was 9.47 s; the threshold value of the BBS was 54 points, respectively. The threshold value of the TUG test between the locomotive syndrome and sarcopenia groups was 10.27 s, and the threshold value of the BBS was 50 points, respectively. These findings suggest that sarcopenia is closely related to locomotive syndrome, and that sarcopenia and locomotive syndrome can be identified using a physical therapy diagnostic evaluation tool.

RESUMEN

BACKGROUND: Patellofemoral pain (PFP) is characterized by anterior knee, which intensifies during functional activities that require the eccentric action of the quadriceps muscle, specially. In ths way, quantitatively measurable functional tests that simulate these activities should be included in the physical therapy evaluation. OBJECTIVE: To identify which functional tests are most indicated for the evaluation of women with PFD. METHOD: This study evaluated 100 young women (50 with PFP), during the execution of the following functional performance tests: Triple hop, Vertical Jump, Single leg squat, Step Down, YBalance tests, Lunge test and running. Dynamic valgus was also assessed in the tests. The isometric muscle strength of the following muscle groups: hip abductors, extensors and lateral rotators, knee extensors, evertors, and plantar flexors were evaluated. Functional Perception were evaluated by Anterior Knee Pain Scale and Activities of Daily Living Scale. RESULTS: PFP group showed lower performance during the Y-Balance, triple hop, vertical jump tests and running. Was observed an increase in dynamic valgus during Triple Hop, Vertical Jump tests and running in PFP group, besides a poorer perception of function. For all lower limb muscle groups, the PFP group showed a reduction in peak isometric force. CONCLUSION: The YBalance, triple hop, vertical jump tests, and running should be included in the physical therapy evaluation, in addition to aspects of lower limb muscle strength.

RESUMEN

Rorschach and self-report instruments represent methodologically different types of assessment, which together may yield incremental information about the test-taker. There is little evidence on whether and when results from these methods converge. OBJECTIVE: To examine possible convergences between Rorschach trauma-related personality variables and self-reported variables. METHOD: Before and after psychotherapy 22 traumatized adult refugee patients were assessed with the Rorschach Performance Assessment System (R-PAS), symptom checklists of posttraumatic stress, anxiety and depression, and a quality of life questionnaire. Correlational analyses between eight R-PAS variables and 10 self-reported variables were performed. RESULTS: The findings showed inconsistent and nonsignificant correlations pretherapy. Posttherapy, however, all R-PAS variables except Complexity correlated positively with symptoms of mental disorder, and negatively with the quality of life variables, as predicted. The R-PAS variables Mutuality of Autonomy-Pathology, Poor Human Representation, Critical Content, and Form Quality-minus%, converged significantly with most of the self-reported variables, with medium to large correlations. CONCLUSION: The finding of convergence only after psychotherapy, may tentatively suggest greater self-knowledge and internal consistency through the therapy experience, and increased trust and self-disclosure through the repeated meetings with the researchers. The findings represent a promising contribution to a cumulative validation process of convergence between Rorschach and self-report data.

RESUMEN

Background: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating chronic condition with no identified diagnostic biomarkers to date. Its prevalence is as high as 0.89% according to metastudies, with a quarter of patients bed- or home-bound, which presents a serious public health challenge. Investigations into the inflammation-immunity axis is encouraged by links to outbreaks and disease waves. Recently, the research of our group revealed that antibodies to beta2-adrenergic (anti-ß2AdR) and muscarinic acetylcholine (anti-M4) receptors demonstrate sensitivity to the progression of ME/CFS. The purpose of this study is to investigate the joint potential of inflammatome-characterized by interferon (IFN)-γ, tumor necrosis factor (TNF)-α, interleukin (IL)-2, IL-21, Il-23, IL-6, IL-17A, Activin-B, immunome (IgG1, IgG2, IgG3, IgG4, IgM, and IgA), and receptor-based biomarkers (anti-M3, anti-M4, and anti-ß2AdR)-for evaluating ME/CFS progression, and to identify an optimal selection for future validation in prospective clinical studies. Methods: A dataset was used originating from 188 individuals, namely, 54 healthy controls, 30 patients with a "mild" condition, 73 patients with a "moderate" condition, and 31 patients with a "severe" condition, clinically assessed by Fukuda/CDC 1994 and international consensus criteria. Inflammatome, immunome, and receptor-based biomarkers were determined in blood plasma via ELISA and multiplex methods. Statistical analysis was done via correlation analysis, principal component analysis, linear discriminant analysis, and random forest classification; inter-group differences were tested via nonparametric Kruskal-Wallis H test followed by the two-stage linear step-up procedure of Benjamini, Krieger, and Yekutieli, and via Mann-Whitney U test. Results: The association between inflammatome and immunome markers is broader and stronger (coupling) in the severe group. Principal component factoring separates components associated with inflammatome, immunome, and receptor biomarkers. Random forest modeling demonstrates an excellent accuracy of over 90% for splitting healthy/with condition groups, and 45% for splitting healthy/severity groups. Classifiers with the highest potential are anti-ß2AdR, anti-M4, IgG4, IL-2, and IL-6. Discussion: The association between inflammatome and immunome markers is a candidate for controlled clinical study of ME/CFS progression markers that could be used for treatment individualization. Thus, the coupling effects between inflammation and immunity are potentially beneficial for the identification of prognostic factors in the context of ME/CFS progression mechanism studies.

RESUMEN

PURPOSE: Neo-adjuvant chemotherapy (NAC) is used in breast cancer before tumor surgery to reduce the size of the tumor and the risk of spreading. Monitoring the effects of NAC is important because in a number of cases the response to therapy is poor and requires a change in treatment. A new method that uses quantitative ultrasound to assess tumor response to NAC has been presented. The aim was to detect NAC unresponsive tumors at an early stage of treatment. METHODS: The method assumes that ultrasound scattering is different for responsive and nonresponsive tumors. The assessment of the NAC effects was based on the differences between the histograms of the ultrasound echo amplitude recorded from the tumor after each NAC dose and from the tissue phantom, estimated using the Kolmogorov-Smirnov statistics (KSS) and the symmetrical Kullback-Leibler divergence (KLD). After therapy, tumors were resected and histopathologically evaluated. The percentage of residual malignant cells was determined and was the basis for assessing the tumor response. The data set included ultrasound data obtained from 37 tumors. The performance of the methods was assessed by means of the area under the receiver operating characteristic curve (AUC). RESULTS: For responding tumors, a decrease in the mean KLD and KSS values was observed after subsequent doses of NAC. In nonresponding tumors, the KLD was higher and did not change in subsequent NAC courses. Classification based on the KSS or KLD parameters allowed to detect tumors not responding to NAC after the first dose of the drug, with AUC equal 0.83 ± $\pm$ 0.06 and 0.84 ± $\pm$ 0.07, respectively. After the third dose, the AUC increased to 0.90 ± $\pm$ 0.05 and 0.91 ± $\pm$ 0.04, respectively. CONCLUSIONS: The results indicate the potential usefulness of the proposed parameters in assessing the effectiveness of the NAC and early detection of nonresponding cases.

RESUMEN

BACKGROUND: Total thyroidectomy (TT) or lobectomy without radioactive iodine (RAI) is becoming a common management for patients with low-risk differentiated thyroid cancer (DTC). However, the assessment of response to therapy for these patients remains controversial. The aim of this study was to propose and validate a new dynamic evaluation strategy to assess the response to therapy in patients with low-risk DTC treated with TT or lobectomy but without RAI. METHODS: We performed a retrospective analysis of 543 adult patients with low-risk DTC who underwent TT or lobectomy without RAI therapy. Follow-up consisted of trends of serum thyroglobulin (Tg), anti-thyroglobulin antibody (TgAb) levels and neck ultrasonography (US) were conducted every 6-24 months. Response to therapy assessments were defined as excellent response, biochemical incomplete response, structural incomplete response, and indeterminate response according to the follow-up findings. RESULTS: At a median follow-up of 51 months (range 33-66 months), 517 (95%) had excellent response, while the other 26 had either biochemical incomplete response (an increasing trend of suppressed serum Tg levels, n=9; an increasing trend of TgAb levels, n=3) or indeterminate response (a stable or decreasing trend of suppressed serum Tg levels, but a stable positive trend of TgAb levels, n=14). No patients had structural incomplete response or no deaths related to thyroid cancer. The risk of incomplete response was significantly higher in lobectomy than in TT (p<0.001). CONCLUSION: Our study proposed and validated a new dynamic response to therapy assessment depending on trends of suppressed serum Tg, TgAb levels, and neck US findings which could be an appropriate tool for postoperative follow-up in low-risk DTC patients without RAI therapy. Our findings provided further evidence to support no routine recommendation of RAI after surgery in low-risk DTC.

RESUMEN

OBJECTIVES: Dermatomycoses of zoophilic origin, especially those caused by Trichophyton mentagrophytes, often pose considerable therapeutic problems. This is reflected in the growing number of strains of this species with resistance to terbinafine caused by a mutation in the squalene epoxidase (SQLE) gene. Therefore, it is reasonable to look for alternative therapies to the commonly used terbinafine. The aim of the present study was to assess the in vivo effectiveness of topical therapy with luliconazole or terbinafine 1% cream. METHODS: Therapeutic efficacy was assessed using direct examination in KOH with DMSO, qPCR analysis with pan-dermatophyte primers and culturing. Moreover, in vitro susceptibility tests for luliconazole and terbinafine were performed. RESULTS: The results demonstrated significantly higher antifungal activity of luliconazole than terbinafine against dermatomycoses caused by T. mentagrophytes. The geometric mean of the MIC value for luliconazole against all T. mentagrophytes strains was 0.002 µg/ml, while this value for terbinafine was 0.004 µg/ml. In all studied cases, 28-day local therapy with luliconazole contributed to complete eradication of the aetiological agent of infection. CONCLUSIONS: Given the increasingly frequent reports of difficult-to-treat dermatophytoses caused by zoophilic terbinafine-resistant strains, the 1% luliconazole cream can be alternative solution in topical therapy.

RESUMEN

Background: Pharmacist-facilitated medicines review services have been postulated as a way to address current inequities in health outcomes between Maori and non-Maori. These interventions have been shown internationally to improve the appropriate use of medicines but remain underutilised in Aotearoa New Zealand (NZ). By reviewing the literature and engaging with key stakeholders, we developed an intervention, which included collaborative goal-setting, education and medicines optimisation, for testing in a feasibility study. Objective: To determine the feasibility (recruitment, intervention delivery, and data collection methods) of a pharmacist-facilitated medicines review intervention for Maori older adults, and proposed intervention outcomes. Methods: This study was reported in accordance with the CONSORT 2010 statement: extension to randomised controlled pilot and feasibility trials and the Consolidated criteria for strengthening reporting of health research involving indigenous peoples: the CONSIDER statement. Participant eligibility criteria were: Maori; aged 55-plus; community-dwelling; enrolled in a general practice in Waitemata District Health Board (Auckland, NZ). Consented participants engaged in a medicines education component (participant and pharmacist) and an optional medicines optimisation component (participant, pharmacist and prescriber). Outcomes measures included: the feasibility of data collection tools and methods, time taken to conduct the intervention and research processes; medicines knowledge, medicines appropriateness and quality of life (QoL); pharmacist recommendations and prescriber acceptance rate. Results: Seventeen consented participants took part in the intervention from December 2019-March 2020 with the majority (n = 12) recruited through general practice mail-outs. Data collection was feasible using the predetermined outcome measure tools and was complete for all patient participants. Pharmacist intervention delivery was feasible. A mean of 9.5 recommendations were made per participant with a prescriber acceptance rate of 95%. These included non-medicine-related recommendations. Conclusion: The feasibility testing of pharmacist-facilitated medicines review intervention developed for (and with) community-dwelling Maori older adults allows for intervention refinement and can be utilised for further studies relating to pharmacist services in primary care.

RESUMEN

Rhabdomyosarcoma is the most common soft-tissue sarcoma of childhood. Despite clinical advances, subsets of these patients continue to suffer high morbidity and mortality rates associated with their disease. Following the European guidelines for 18F-FDG PET and PET-CT imaging in pediatric oncology, the routine use of 18F-FDG PET-CT may be useful for patients affected by rhabdomyosarcoma, in staging, in the evaluation of response to therapy, and for restaging/detection of relapse. The European Pediatric Protocols are very old, and for staging and restaging, they recommend only radionuclide bone scan. The 18F-FDG PET-CT exam is listed as an optional investigation prescribed according to local availability and local protocols in the investigations panel required at the end of the treatment. We present two cases highlighting the usefulness of 18F-FDG PET-CT in managing pediatric patients affected by rhabdomyosarcoma, providing some bibliographic references.

RESUMEN

PURPOSE: To determine whether foam density affects modified Romberg balance test performance. MATERIALS AND METHODS: Controls and patients with vestibular disorders performed Romberg tests on medium and medium firm foam, with their eyes closed and the head still and moving in yaw and pitch. The trial duration and number of head movements were measured. RESULTS: Subjects aged >60 years performed longer and with more head movements on medium firm foam than on medium foam. Older controls did not differ between medium firm and medium foam. Older patients had higher scores on head-still and head-yaw trials on medium firm foam versus medium foam but pitch trials did not differ. Females, controls, and patients had longer trial durations and more head movements on medium firm foam than on medium density foam; male controls did not differ by foam density. Male patients differed in yaw trials. CONCLUSION: Foam density affects scores. Clinical decision-making may be adversely affected if the clinician uses foam of a density that is not the same as that of the foam that was used in the studies that developed descriptive statistics, sensitivity, and specificity.

RESUMEN

@#Inappropriate responses towards sensory input received from the environment, also known as sensory processing difficulties (SPD) may affect daily living activities of the children with Autism Spectrum Disorder (ASD). Sensory Processing Measure Home Form (SPM Home Form) as a parent report measure for SPD is available in English and other foreign languages. To enhance the applicability and meaningfulness of SPM Home Form for the Malay speaking population, a study that focuses on translating, adapting, and validating the SPM Home Form into the Malay language was conducted. The development of the Malay version of the SPM Home Form (SPM-MV Home Form) involved three steps: 1) Item evaluation, 2) Forward and backward translation, and 3) Expert review and content validity. The process of translation and adaptation of the form was performed according to standard guidelines. No item was excluded from the original SPM Home Form as all the items were considered by the expert panel as appropriate and relevance to evaluate the activity and social participation among children in Malaysia. Content validity as measured by 10 experts in occupational therapy is high. The mean of sub-scales I-CVI is between 0.96 and 1.00. The total S-CVI of the form is 0.95 with sub-scales S-CVI range between 0.82 and 1.00. Cronbach’s alpha for internal consistency was reported at 0.80 and ICC for test-retest reliability ranged from 0.80 to 0.97. The SPM-MV Home Form has high potential to be used for assessing SPD among children ages 5-12 years in Malaysia.

RESUMEN

BACKGROUND: Research has long investigated the cognitive processes in the treatment of depression, and more recently in panic disorder (PD). Meanwhile, other studies have examined patients' cognitive therapy skills in depression to gain insight into the link between acquiring such skills and treatment outcome. AIMS: Given that no scale exists to examine in-session patient use of panic-related cognitive behavioural therapy (CBT) skills, the aim of this study was to develop a new measure for assessing patients' cognitive and behavioural skills in CBT for PD. METHOD: This study included 20 PD patients who received 12 weekly individual therapy sessions. The Cognitive Behavioral Therapy Panic Skills (CBTPS) rating system was developed. Three independent raters coded tapes of therapy sessions at the beginning and end of treatment. RESULTS: The coefficient alphas and inter-rater reliability were high for the cognitive and behavioural subscales. Improvement in the patients' CBTPS scores on both subscales indicated overall symptom improvement, above improvement in anxiety sensitivity. CONCLUSION: To our knowledge, this is the first study examining the impact of patient acquisition of CBT PD skills on treatment outcome. A new measure was developed based on the observations and was deemed reliable and valid. The measure facilitates the examination of the mechanisms of change in treatment for PD. An in-depth examination of the CBTPS may refine our understanding of the impact of each skill on PD treatment outcome. Further research relating to acquiring CBT skills could shed light on the mechanisms of change in treatment.

RESUMEN

Fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) is the imaging method of choice in sarcoma patients. PET may help in diagnosis, grading, staging, biopsy guidance, monitoring response to therapy, restaging for recurrence, and prognosis. 18F-FDG-PET/MRI combines the higher tissue contrast of MRI in the study of soft-tissue lesions and the peculiarities of PET imaging that allow the characterization of tissues. The use of 18F-FDG-PET/MRI in these patients has reduces the radiation dose, which is of great importance, particularly in children. Data support the routine use of 18F-FDG-PET either using CT or MRI in patients with sarcoma.

RESUMEN

BACKGROUND/AIM: Knowledge and understanding of deficits in executive functions has expanded in recent years and its relevance to occupational therapy has been established. The purpose of this review was to identify, analyse, synthesise and describe the updated occupational therapy scientific literature that addresses the subject of executive functions, specifically focusing on children and adolescents. METHOD: Scoping review methodology was implemented to map the occupational therapy literature on executive functions in children and adolescents over the past decade. Articles were retrieved from five electronic databases. RESULTS: Fifty publications met the inclusion criteria. The research included a wide age range, different diagnoses, use of diverse executive functions definitions and assortment of assessments and interventions. CONCLUSION: A unique definition of executive functions among children and adolescents was proposed. This definition can assist both clinicians and researchers in the field. Continued research to establish the profession in a key position is recommended to understand the underlying mechanisms of daily performance.
