Effects of Trichoderma harzianum and Bacillus subtilis on the root and soil microbiomes of the soybean plant INTACTA RR2 PRO™.

Introduction: Soybean is a significant export product for several countries, including the United States and Brazil. There are numerous varieties of soybean. Among them, a genetically modified type known as INTACTA RR2 PRO™ has been designed to demonstrate resistance to glyphosate and to produce toxins that are lethal to several species of caterpillars. Limited information is available on the use of Trichoderma harzianum and Bacillus subtilis to promote plant growth and their impact on the plant microbiome. Methods: This study aimed to evaluate the effects of these microorganisms on this soybean cultivar by analyzing parameters, such as root and shoot dry matter, nutritional status, and root and soil microbial diversity. Results: The results indicated that treatments with B. subtilis alone or in combination with T. harzianum as seed or seed and soil applications significantly enhanced plant height and biomass compared to the other treatments and the control. No significant differences in phosphorus and nitrogen concentrations were detected across treatments, although some treatments showed close correlations with these nutrients. Microbial inoculations slightly influenced the soil and root microbiomes, with significant beta diversity differences between soil and root environments, but had a limited overall impact on community composition. Discussion: The combined application of B. subtilis and T. harzianum particularly enhanced plant growth and promoted plant-associated microbial groups, such as Rhizobiaceae, optimizing plant-microbe interactions. Furthermore, the treatments resulted in a slight reduction in fungal richness and diversity.

Land- and water-based aerobic exercise program on health-related outcomes in breast cancer survivors (WaterMama): study protocol for a randomized clinical trial.

BACKGROUND: Breast cancer is a prevalent form of cancer among women worldwide, often accompanied by physical and psychological side effects due to the disease and the treatment's aggressiveness. Regular physical exercise has emerged as a non-pharmacological approach to improve the quality of life of breast cancer survivors. We herein report the protocol of the WaterMama Study, which aims to evaluate the effects of land- or water-based aerobic exercise programs, compared to a health education program, on cancer-related fatigue and other health-related outcomes in breast cancer survivors. METHODS: The WaterMama trial is a randomized, single-blinded, three-arm, parallel, superiority trial. We aim to recruit 48 women ≥ 18 years of age who have completed primary treatment for stage I-III breast cancer. Participants are randomly allocated in a 1:1:1 ratio to 12-week interventions of aerobic exercise training programs either in the aquatic or land environment (two weekly 45-min sessions) plus health education (a weekly 45-min session), or an active-control group receiving health education alone (a weekly 45-min session). The primary outcome is cancer-related fatigue, and the secondary outcomes include cardiorespiratory fitness, muscular performance, muscle morphology, functional capacity, mental health, cognitive function, pain, and quality of life. Outcomes assessments are conducted before and after the 12-week intervention period. The analysis plan will employ an intention-to-treat approach and per protocol criteria. DISCUSSION: Our conceptual hypothesis is that both aerobic exercise programs will positively impact primary and secondary outcomes compared to the health education group alone. Additionally, due to its multi-component nature, we expect the aquatic exercise program promote more significant effects than the land exercise program on cancer-related fatigue, muscular outcomes, and pain. TRIAL REGISTRATION: The study was prospectively registered at ClinicalTrials.gov NCT05520515. Registered on August 26, 2022. https://clinicaltrials.gov/ct2/show/NCT05520515.

Endothelium-related biomarkers and cognitive decline in prevalent hemodialysis patients: A prospective cohort study.

INTRODUCTION: Cognitive decline is prevalent in maintenance hemodialysis patients. The blood-brain barrier has been implicated in cognitive decline. In this prospective cohort study, we investigated the associations between endothelium-related biomarkers and steeper cognitive decline in this population. METHODS: Cognitive function was assessed using the Portuguese-adapted Cambridge Cognitive Examination (CAMCOG) with items of the Mini-Mental State Examination (MMSE). Endothelium-related biomarkers included syndecan-1, ICAM-1, VCAM-1 and angiopoietin-2 (AGPT2). Patients were followed up for 4 years, and cognitive assessments were repeated. Multinomial regression analyses were performed to evaluate associations between biomarkers and cognitive decline. RESULTS: A total of 216 patients completed the test battery at baseline. After 4 years, 102 patients had follow-up data. There was a significant decrease in cognitive function according to the CAMCOG and MMSE scores: a change of -0.39 (95% CI -0.27 to -0.51) and -0.51 (95% CI -0.27 to -0.76) standard deviation (SD) of the baseline scores. Additionally, executive function but not memory significantly decreased. Syndecan-1 level was independently associated with steeper cognitive decline; each increase in the SD of the syndecan-1 level was associated with a decrease in the CAMCOG of 0.20 (95% CI 0.07-0.33) SD from baseline. Syndecan-1 was associated with a steeper decline in MMSE score (ß 0.54, 95% CI 0.28-0.81) and executive function (ß 0.17, 95% CI 0.02-0.32). Syndecan-1 predicted severe cognitive impairment with an area under the curve for receiver operating characteristic curves of 0.75 (95% CI 0.64-0.83). CONCLUSION: Our findings highlight the potential of syndecan-1, a biomarker of endothelium glycocalyx derangement, as a predictor of steeper cognitive decline in prevalent hemodialysis patients.

Endothelium-related biomarkers enhanced prediction of kidney support therapy in critically ill patients with non-oliguric acute kidney injury.

Acute kidney injury (AKI) is a common condition in hospitalized patients who often requires kidney support therapy (KST). However, predicting the need for KST in critically ill patients remains challenging. This study aimed to analyze endothelium-related biomarkers as predictors of KST need in critically ill patients with stage 2 AKI. A prospective observational study was conducted on 127 adult ICU patients with stage 2 AKI by serum creatinine only. Endothelium-related biomarkers, including vascular cell adhesion protein-1 (VCAM-1), angiopoietin (AGPT) 1 and 2, and syndecan-1, were measured. Clinical parameters and outcomes were recorded. Logistic regression models, receiver operating characteristic (ROC) curves, continuous net reclassification improvement (NRI) and integrated discrimination improvement (IDI) were used for analysis. Among the patients, 22 (17.2%) required KST within 72 h. AGPT2 and syndecan-1 levels were significantly greater in patients who progressed to the KST. Multivariate analysis revealed that AGPT2 and syndecan-1 were independently associated with the need for KST. The area under the ROC curve (AUC-ROC) for AGPT2 and syndecan-1 performed better than did the constructed clinical model in predicting KST. The combination of AGPT2 and syndecan-1 improved the discrimination capacity of predicting KST beyond that of the clinical model alone. Additionally, this combination improved the classification accuracy of the NRI and IDI. AGPT2 and syndecan-1 demonstrated predictive value for the need for KST in critically ill patients with stage 2 AKI. The combination of AGPT2 and syndecan-1 alone enhanced the predictive capacity of predicting KST beyond clinical variables alone. These findings may contribute to the early identification of patients who will benefit from KST and aid in the management of AKI in critically ill patients.

Plant Growth-Promoting Rhizobacteria for Sustainable Agricultural Production.

Rhizosheric bacteria with several abilities related to plant growth and health have been denominated Plant Growth-Promoting Rhizobacteria (PGPR). PGPR promote plant growth through several modes of action, be it directly or indirectly. The benefits provided by these bacteria can include increased nutrient availability, phytohormone production, shoot and root development, protection against several phytopathogens, and reduced diseases. Additionally, PGPR can help plants to withstand abiotic stresses such as salinity and drought and produce enzymes that detoxify plants from heavy metals. PGPR have become an important strategy in sustainable agriculture due to the possibility of reducing synthetic fertilizers and pesticides, promoting plant growth and health, and enhancing soil quality. There are many studies related to PGPR in the literature. However, this review highlights the studies that used PGPR for sustainable production in a practical way, making it possible to reduce the use of fertilizers such as phosphorus and nitrogen and fungicides, and to improve nutrient uptake. This review addresses topics such as unconventional fertilizers, seed microbiome for rhizospheric colonization, rhizospheric microorganisms, nitrogen fixation for reducing chemical fertilizers, phosphorus solubilizing and mineralizing, and siderophore and phytohormone production for reducing the use of fungicides and pesticides for sustainable agriculture.

Impact of Resistance Training Volume on Physical and Perceptual Outcomes of Breast Cancer Survivors Submitted to a Combined Training Program: A Randomized, Single-Blinded Study.

BACKGROUND: To determine the effect of resistance training volume on physical and perceptual outcomes of breast cancer survivors submitted to a combined training program. DESIGN: Randomized single-blinded study. METHODS: Nineteen breast cancer survivor women were randomized to a single-set (SS) or a multiple-set (MS) group. Both groups completed an 8-week combined training intervention in which the SS and MS groups performed 1 and 3 sets per resistance exercise, respectively. The following outcomes were assessed preintervention and postintervention: maximal knee extension dynamic strength (1-repetition maximum), quadriceps muscle thickness, peak oxygen uptake, time to exhaustion, cancer-related fatigue, and quality of life. RESULTS: Both interventions increased knee extension 1-repetition maximum (SS: 29.8% [37.5%]; MS: 19.3% [11.8%]), quadriceps muscle thickness (9.4% [4.1%]; 8.9% [5.9%]), and quality of life (4.3% [6.3%]; 7.9% [9.0%]), with no difference between the groups. However, only MS improved cancer-related fatigue (-2.1% [1.7%]) and time to exhaustion (21.3% [14.9%]), whereas peak oxygen uptake remained unchanged in both groups. CONCLUSIONS: Cancer-related fatigue and time to exhaustion, improved only in the MS group after the intervention. On the other hand, similar knee extension 1-repetition maximum, quadriceps muscle thickness, and quality of life improvements were observed in breast cancer survivors irrespective of the resistance training volume performed.

Conceptual mapping proposed to comprehend the effect of wheelchair mobility on social participation and quality of life: a systematic review.

PURPOSE: To identify and synthesise the available evidence on the effect of mobility on social participation and quality of life (QoL) of wheelchairs (WC) on adults who use WC as their primary means of mobility. MATERIALS AND METHODS: Systematic review undertaken in accordance with the Centre for Reviews and Dissemination Guidelines and registered in the PROSPERO International Prospective Register of Systematic reviews. Nine electronic databases (MEDLINE via PubMed, EMBASE, Cochrane Library, LILACS, CINAHL, PEDro, SCOPUS, Web of Science, and BVS ECOS) were searched with the following PICO eligibility criteria: (P) Population was individuals with mobility limitations that live in their community, aged 18 or older; (I) Intervention was mobility devices, such as manual and powered wheelchairs; (C) Comparators, not applied; (O) Outcome was factors that can be influenced by wheelchair use, such as: social participation, health-related quality of life and QOL. Critical appraisal of methodological quality of studies were undertaken. RESULTS: A total of 18 studies were included. The proportion of studies evaluating the effects of mobility on participation was higher than to mobility on QoL. WC quality, device benefit (ease of repairs and maintenance), confidence using a WC and WC skills were key factors determining participation. The provision of WC according to the eight steps service proposed by the Word Health Organisation contributed to higher levels of physical health, WC satisfaction, hours using the WC and QoL enhancement. CONCLUSION: Attention should be given to enhance WC service provision (with continuous service support) as well as professional continuing education.IMPLICATIONS FOR REHABILITATIONWheelchair technology is a key element in rehabilitation. Significant effort should be made to provide and maintain the wheelchair as a facilitator to participation. A great attention should be done to enhance wheelchair services as well as professional continuous education.Wheelchair skills are associated with participation and may be targeted in clinical intervention.

Exercise intervention does not reduce the likelihood of VO2max underestimation in older adults with hypertension.

The present study aimed to investigate whether training status would influence the capacity of a verification phase (VER) to confirm maximal oxygen uptake (VO2max) of a previous graded exercise test (GXT) in individuals with hypertension. Twelve older adults with hypertension (8 women) were recruited. Using a within-subject design, participants performed a treadmill GXT to exhaustion followed by a multistage VER both before and after a 12-wkcombined exercise training programme. Individual VO2max, respiratory exchange ratio (RER), maximal heart rate (HRmax), and rating of perceived exertion (RPE) were measured during both GXT and VER tests. Absolute and relative VO2max values were higher in VER than in GXT at baseline, but only absolute VO2max differed between bouts post-intervention (all p < 0.05). Individual VO2max comparisons revealed that 75% of the participants (9/12) achieved a VO2max value that was ≥3% during VER both before (range: +4.9% to +21%) and after the intervention (range: +3.4% to +18.8%), whereas 91.7% (11/12) of the tests would have been validated as a maximal effort if the classic criteria were employed. A 12-wk combined training intervention could not improve the capacity of older adults with hypertension to achieve VO2max during a GXT, as assessed by VER.

Cardiorespiratory Parameters Comparison Between Incremental Protocols Performed in Aquatic and Land Environments by Healthy Individuals: A Systematic Review and Meta-Analysis.

BACKGROUND: Physical properties of water cause physiological changes in the immersed human body compared with the land environment. Understanding the magnitude of cardiorespiratory alterations might ensure adequate intensity control during aquatic exercise programs. OBJECTIVE: We aimed to compare the oxygen uptake (VO2), heart rate (HR), and rating of perceived exertion (RPE) parameters during aquatic and land incremental tests. METHODS: Four databases (PubMed, LILACS, EMBASE, and SPORTDiscus) were searched in September 2020. Eligibility criteria included studies in a crossover design comparing aquatic and land incremental tests for healthy individuals with at least one of the following parameters: VO2 (maximal, VO2max; anaerobic threshold, VO2AT), HR (HRmax; HRAT), and RPE (RPEmax; RPEAT). The random-effects meta-analysis included mean difference and 95% confidence interval for VO2 and HR or standardized mean difference for RPE. The Joanna Briggs Institute Critical Appraisal tool was adapted to assess methodological quality. RESULTS: Twenty-eight studies were eligible and included in the meta-analysis. Aquatic protocols showed lower values compared with land for VO2max (- 7.07 mL.kg-1.min-1; - 8.43 to - 5.70; n = 502), VO2AT (- 6.19 mL.kg-1.min-1; - 7.66 to - 4.73; n = 145), HRmax (- 11.71 bpm; - 13.84 to - 9.58; n = 503), and HRAT (- 15.29 bpm; - 19.05 to - 11.53; n = 145). RPEmax (0.01; - 0.16 to 0.18; n = 299) and RPEAT (- 0.67; - 1.35 to 0.02; n = 55) values were similar between aquatic and land protocols. CONCLUSIONS: Our study reinforces the specificity of the environment during incremental tests for prescribing exercises based on physiological parameters as VO2 and HR parameters presented lower values in aquatic protocols than land protocols. Conversely, RPE seems an interchangeable measure of exercise intensity, with similar values during the protocols in both environments. Substantial levels of heterogeneity were present for the VO2max and HRmax meta-analyses, and as such, results should be interpreted with attention. PROTOCOL REGISTRATION: This study was registered in the International Prospective Register of Systematic Reviews (PROSPERO; CRD42020212508).

High-velocity resistance training mitigates physiological and functional impairments in middle-aged and older adults with and without mobility-limitation.

The aim of the present study was to compare the neuromuscular, morphological, and functional responses to a high-velocity resistance training (HVRT) program between three cohorts: middle-aged adults (40-55 years, n = 18), healthy older adults (> 60 years, n = 18), and mobility-limited older adults (n = 8). Participants were tested before and after a 4-week control period and then assigned to a 12-week HVRT intervention. Investigated outcomes included ultrasound-derived muscle thickness and quality, maximal dynamic strength (1RM), maximal voluntary isometric contraction (MVIC), and muscle activation (sEMG), as well as muscle power and functional performance. After the intervention, quadriceps muscle thickness, 1RM, and sEMG improved in all three groups (all p < 0.05), whereas muscle quality improved only in middle-aged and older participants (p ≤ 0.001), and MVIC only in middle-aged and mobility-limited older adults (p < 0.05). With a few exceptions, peak power improved in all groups from 30-90% 1RM (p < 0.05) both when tested relative to pre-training or post-training 1RM workloads (all p < 0.05). Both mobility-limited older adults and older adults improved their short physical performance battery score (p < 0.05). Chair stand, stair climb, maximal gait speed, and timed up-and-go performance, on the other hand, improved in all three groups (p < 0.05), but no change was observed for habitual gait speed and 6-min walk test performance. Overall, our results demonstrate that a HVRT intervention can build a stronger foundation in middle-aged individuals so that they can better deal with age-related impairments at the same time that it can mitigate already present physiological and functional impairments in older adults with and without mobility-limitation.

Quality of life responses after combined and aerobic water-based training programs in older women: a randomized clinical trial (ACTIVE Study).

BACKGROUND: Quality of life (QoL) is an important health index for older adults. AIM: The aim of this study was to compare the effects of 16 weeks of aerobic training to 8 weeks of aerobic followed by 8 weeks of combined (i.e., resistance and aerobic exercises) training, as well as to a control group on the QoL of older women exercising in the aquatic environment. METHODS: 52 older women were first randomized to either aerobic training (n = 35) or a control group (n = 17). After 8 weeks of intervention, participants initially assigned to the aerobic training group were again randomized to either 8 additional weeks of aerobic (n = 17) or combined training (n = 18). Aerobic training was performed at the heart rate percentage associated with the anaerobic threshold, while resistance training sets were performed at maximal effort. The control group performed low-intensity water-based therapeutic exercises. QoL was assessed before (week 0) and after the intervention (week 17) using the WHOQOL-BREEF and WHOQOL-OLD questionnaires. Generalized Estimating Equations (GEE) and Bonferroni post hoc tests (α = 0.05) were used to compare time points and groups. RESULTS: QoL improved significantly only in the training groups after the 16-week training intervention, whereas it remained unchanged in the control group. In addition, autonomy, environment, and present, past and future activities domains were more impacted after combined training. CONCLUSION: QoL improved only in the water-based training groups, and the addition of resistance exercises to the training program resulted in additional benefits to autonomy, environment, and past, present, and future activities domains.

Victim and villain: ambiguous experience of nursing students in the university context.

OBJECTIVE: To understand how Undergraduate Nursing Students signify the university context. METHOD: A qualitative research, of a phenomenological nature, based on the ontology of Maurice Merleau-Ponty, with the participation of 41 undergraduate nursing students from a public university in the interior of Bahia, Brazil. Data were collected from February to April 2019, using four wheels of Community Therapy, whose produced material was submitted to the Analytical of Ambiguity technique. RESULTS: From the analysis of the experiential descriptions, two categories emerged that reveal the significance attributed by students to their experiences in the university context: the university that generates suffering and the university that provides growth. FINAL CONSIDERATIONS: Undergraduate Nursing students signify the university context as an ambiguous experience, at the same time that the university is seen as generating suffering, it is also seen as capable of providing intellectual, sociocultural, affective and political growth.

Self-care related to the performance of occupational roles in patients under antineoplastic chemotherapy treatment.

OBJECTIVE: to analyze and correlate occupational roles, symptoms and self-care capacity in oncologic patients seen at the chemotherapy service of a university hospital. METHOD: cross-sectional study, in which the instruments were applied sociodemographic and clinical questionnaire, M.D Anderson's Symptom Inventory - core, Appraisal of Self Care Agency Scale-Revised and Occupational Paper Identification List to oncologic patients seen in the chemotherapy service of a university hospital. Data analysis included absolute and relative frequency tables and multiple linear regression, adopting a significance level of α=0.05. RESULTS: the sample showed capacity for self-care operationalized with an average of ̄X=57.8. In the correlation between the degree of importance of the occupational papers and the scores of the evaluation instrument for self-care was found statistical significance in the papers of volunteer (r=0.26; p=0.02) and friend (r=0.33; p= <0.001). The linear regression showed that the greater the interference of symptoms in life activities (ß=0.20; p=0.05) and greater the importance of the role of friend (p=0.001; p=0.43), the higher the rates of self-care. CONCLUSION: the operationalization of self-care can be directly related to the degree of importance attributed to the performance of social roles.

Anaerobic Threshold in a Water-Based Exercise: Agreement Between Heart Rate Deflection Point and Lactate Threshold Methods.

ABSTRACT: Alberton, CL, Andrade, LS, Pinheiro, RB, and Pinto, SS. Anaerobic threshold in a water-based exercise: agreement between heart rate deflection point and lactate threshold methods. J Strength Cond Res 35(9): 2472-2478, 2021-The purpose of this study was to compare and assess the agreement of the heart rate (HR) and rating of perceived exertion (RPE) corresponding to the anaerobic threshold (AT) between HR deflection point (HRDP) and lactate threshold (LT) methods during a water-based exercise in young men. Sixteen young men (24 ± 6 years) performed the experimental protocol, which comprised the performance of a maximal incremental test during the water-based stationary running exercise. The initial cadence corresponded to 90 b·min-1, with 10 b·min-1 increases every 3 minutes up to exhaustion. Heart rate was monitored every 30 seconds while blood lactate concentrations and RPE were measured at the end of each 3-minute bout. Anaerobic threshold was identified by HRDP and LT methods by experienced physiologists. Paired Student's t-test, Bland-Altman analysis, and Pearson correlation were used for data analysis (α = 0.05). As results, there was agreement between HRDP and LT methods for HR, while RPE presented significant higher values for the HRDP method, resulting in an absence of acceptable agreement between methods. In addition, strong relationships (p ≤ 0.001) were verified between methods of AT determination for HR (r = 0.786) and RPE (r = 0.916). Therefore, based on the agreement between HRDP and LT methods, the HR determined by HRDP may be a valid parameter used for the intensity prescription of water-based stationary running exercise in young men during water aerobics programs and may be considered more reliable than RPE.

Victim and villain: ambiguous experience of nursing students in the university context / Víctima y villana: experiencia ambigua de estudiantes de enfermería en el contexto universitario / Vítima e vilã: experiência ambígua de estudantes de enfermagem no contexto universitário

ABSTRACT Objective To understand how Undergraduate Nursing Students signify the university context. Method A qualitative research, of a phenomenological nature, based on the ontology of Maurice Merleau-Ponty, with the participation of 41 undergraduate nursing students from a public university in the interior of Bahia, Brazil. Data were collected from February to April 2019, using four wheels of Community Therapy, whose produced material was submitted to the Analytical of Ambiguity technique. Results From the analysis of the experiential descriptions, two categories emerged that reveal the significance attributed by students to their experiences in the university context: the university that generates suffering and the university that provides growth. Final considerations Undergraduate Nursing students signify the university context as an ambiguous experience, at the same time that the university is seen as generating suffering, it is also seen as capable of providing intellectual, sociocultural, affective and political growth.

Self-care related to the performance of occupational roles in patients under antineoplastic chemotherapy treatment / O autocuidado relacionado ao desempenho de papéis ocupacionais em pacientes sob tratamento quimioterápico antineoplásico / Autocuidado relacionado con el desempeño de roles ocupacionales en pacientes bajo tratamiento de quimioterapia antineoplásica

Objective: to analyze and correlate occupational roles, symptoms and self-care capacity in oncologic patients seen at the chemotherapy service of a university hospital. Method: cross-sectional study, in which the instruments were applied sociodemographic and clinical questionnaire, M.D Anderson's Symptom Inventory - core, Appraisal of Self Care Agency Scale-Revised and Occupational Paper Identification List to oncologic patients seen in the chemotherapy service of a university hospital. Data analysis included absolute and relative frequency tables and multiple linear regression, adopting a significance level of α=0.05. Results: the sample showed capacity for self-care operationalized with an average of ̄X=57.8. In the correlation between the degree of importance of the occupational papers and the scores of the evaluation instrument for self-care was found statistical significance in the papers of volunteer (r=0.26; p=0.02) and friend (r=0.33; p= <0.001). The linear regression showed that the greater the interference of symptoms in life activities (β=0.20; p=0.05) and greater the importance of the role of friend (p=0.001; p=0.43), the higher the rates of self-care. Conclusion: the operationalization of self-care can be directly related to the degree of importance attributed to the performance of social roles.

Objetivo: analisar e correlacionar os papéis ocupacionais, os sintomas e a capacidade de autocuidado em pacientes oncológicos atendidos no serviço de quimioterapia de um hospital universitário. Método: estudo transversal, no qual foram aplicados os instrumentos questionário sociodemográfico e clínico, Inventário de Sintomas do M.D Anderson - core, escala de avaliação da capacidade do autocuidado Appraisal of Self Care Agency Scale-Revised e Lista de Identificação de Papéis Ocupacionais em pacientes oncológicos atendidos no serviço de quimioterapia de um hospital universitário. A análise dos dados incluiu tabelas de frequências absolutas e relativas e regressão linear múltipla, adotando nível de significância de α=0,05. Resultados: a amostra apresentou capacidade para o autocuidado operacionalizada com média de ̄X=57,8. Na correlação entre o grau de importância dos papéis ocupacionais e os escores do instrumento de avaliação para o autocuidado foi encontrada significância estatística nos papéis de voluntário (r=0,26; p=0,02) e de amigo (r=0,33; p= <0,001). A regressão linear mostrou que quanto maior a interferência dos sintomas nas atividades de vida (β=0,20; p=0,05) e maior a importância do papel do amigo (p=0,001; p=0,43), maiores os índices de autocuidado. Conclusão: a operacionalização do autocuidado pode estar diretamente relacionada ao grau de importância atribuído ao desempenho de papéis sociais.

Resultados: la muestra ha mostrado capacidad para el autocuidado operacionalizada, con un promedio de ̄X=57,8. En la correlación entre el grado de importancia de los roles ocupacionales y las puntuaciones del instrumento de evaluación para el autocuidado, se encontró significancia estadística para los roles de voluntario (r=0,26; p=0,02) y de amigo (r=0,33; p= <0,001). La regresión lineal mostró que cuanto mayor es la interferencia de los síntomas en las actividades de la vida (β=0,20; p=0,05) y cuanto mayor la importancia del rol del amigo (p=0,001; p=0,43), más altos son los índices de autocuidado. Conclusión: la operacionalización del autocuidado puede estar directamente relacionada con el grado de importancia atribuido al desempeño de los roles sociales.
