Sex-based differences and risk of recurrence in patients with atrial fibrillation undergoing pulmonary vein isolation.

INTRODUCTION: Studies suggest increased likelihood of atrial fibrillation (AF) recurrence after catheter ablation (CA) in women than in men, indicating that sex may be an independent risk factor for recurrence. Nevertheless, the influence of sex on AF recurrence and underlying mechanisms remains unclear. METHODS: Retrospective, single-centre study including patients undergoing AF CA between 2017 and 2021. Late recurrence (LR) was defined as AF recurrence ≥90 days after ablation, whereas early recurrence (ER) occurred within 90 days. RESULTS: 656 patients (32% women) were included, with a median follow-up period of 26 months. Compared to men, women undergoing CA were older, had higher body mass indexes, and had higher rates of hypertension, thyroid dysfunction, and valvular disease. Women also had increased LR risk after CA (HR 1.76, 95% CI [1.19, 2.59]). A time-split multivariable analysis at one year of follow-up showed no difference in LR risk during the first 12 months after CA (HR 1.19, 95% CI [0.73, 1.94]); however, LR risk increased in women (HR 2.90, 95% CI [1.68, 5.01]) after 12 months. In a sex-stratified analysis, coronary calcium score (CCS) >100 was associated with increased LR risk in men (HR 1.81, 95% CI [1.06, 3.08]), but not in women. Cardiac adipose tissue volume (CATV) was not associated with increased LR risk. CONCLUSIONS: Fewer women underwent CA than men and LR was more frequent in women, particularly one year after the procedure. CCS was associated with increased LR risk in men.

Metabolic and ultrastructural renal changes in adult Wistar rats fed by a cafeteria diet.

PURPOSE: To evaluate, by quantitative and qualitative methods, the glomerular ultrastructure in Wistar rats fed a cafeteria diet. METHODS: Male Wistar rats were divided into two groups at 21 days of age: control (C, n = 10) and cafeteria diet (CAF, n = 8). The animals were followed up until 5 months of age, followed by euthanasia. The blood, kidneys, and fat deposits--epididymal, retroperitoneal, and subcutaneous--were extracted and analyzed. Data were analyzed by Student's t test, and p < 0.05 was considered statistically significant. RESULTS: The cafeteria diet promoted glucose intolerance, hyperglycemia (p < 0.0001), and deposition of retroperitoneal fat (p < 0.005). Scanning electron microscopy revealed that the length of the foot process was similar in both groups. The quantitative analyses by transmission electron microscopy revealed that the cafeteria diet reduced the thickness of the glomerular basement membrane (p < 0.05). CONCLUSIONS: The intake of lipids and simple carbohydrates were found to be associated with alteration in the glomerular ultrastructure. However, more studies are needed to evaluate not only the effects of high-protein and high-fat diets on components of the glomerular filtration barrier, but also renal physiology.

Nurse-Led Approaches to Lowering Alcohol Use among Adolescents: Study Findings.

This study delves into how motivational sessions and brief interventions impact students' alcohol consumption, highlighting the vital role of nurses in fostering positive behavioural changes. The study aims to discern the effects of these interventions, starting with a pre-and post-intervention setup involving 62 students from a private school in northern Portugal. The intervention comprised a session delivered by school and mental health nurses, utilizing the motivational intervention and FRAMES method and a poster offering feedback on alcohol consumption scores. The results indicated that females tended to drink for fewer days and engage in less binge drinking than males. Furthermore, the intervention hinted at a reduction in the number of heavy drinking days. This study underscores the importance of including healthcare professionals, particularly nurses, in delivering brief interventions within school settings. The findings carry weight for crafting evidence-based interventions to cultivate healthier adolescent behaviours and enhance overall well-being.

Mental health during ecological crisis: translating and validating the Hogg Eco-anxiety Scale for Argentinian and Spanish populations.

BACKGROUND: Eco-anxiety is increasingly recognized as a shared experience by many people internationally, encompassing fear of environmental catastrophe and anxiety about ecological crises. Despite its importance in the context of the changing climate, measures for this construct are still being developed in languages other than English. METHODS: To contribute to global eco-anxiety research, we translated the Hogg Eco-Anxiety Scale (HEAS) into Spanish, creating the HEAS-SP. We validated this measure in samples from both Argentina (n = 990) and Spain (n = 548), performing measurement invariance and confirmatory factor analyses. Internal consistency of the scale and score stability over time were investigated through reliability analyses. Differences in eco-anxiety across sociodemographic variables were explored through Student's t-tests and Pearson's r tests. RESULTS: The four-factor model of the HEAS-SP comprising affective and behavioural symptoms, rumination, and anxiety about personal impact demonstrated excellent model fit. We found good internal consistency for each subscale, and established measurement invariance between Spanish and Argentine samples, as well as across genders and participants' age. Spanish participants reported higher scores on the affective symptoms and personal impact anxiety factors compared to the Argentinian sample. Also, men reported lower levels than women on the subscales of affective symptoms, rumination, and personal impact anxiety. It was found that the relationship between both age and personal impact anxiety and age and affective symptoms varies significantly depending on the gender of the individuals. Younger participants tended to report higher scores on most dimensions of eco-anxiety. CONCLUSIONS: These findings enhance the global initiative to investigate, explore and therefore comprehend eco-anxiety by introducing the first valid and reliable Spanish-language version of this psychometric instrument for its use within Spanish and Argentinian populations. This study augments the body of evidence supporting the robust psychometric properties of the HEAS, as demonstrated in prior validations for Australian, Turkish, Portuguese, German, French, and Italian populations.

Kidney collecting system anatomy applied to endourology - a narrative review.

OBJECTIVE: To evaluate the surgical anatomy of the kidney collecting system through a narrative review of the literature, highlighting its importance during diagnosis and its approach during surgical procedures for the treatment of renal stones. MATERIAL AND METHODS: We carried out a review about the anatomy of the kidney collecting system. We analyzed papers published in the past 40 years in the databases Pubmed, Embase and Scielo, and we included only papers in English and excluded case reports, editorials and opinions of specialists. RESULTS: Renal collecting system could be divided in four groups: A1 - kidney midzone (KM), drained by minor calyx that are dependent on the superior or the inferior caliceal groups; A2 - KM drained by crossed calyx, one draining into the superior caliceal group and another draining into the inferior caliceal group; B1 - KM drained by a major caliceal group independent of both the superior and inferior groups; and B2 - KM drained by minor calyx entering directly into the renal pelvis. Some details and anatomic variations of the collecting system are related to clinical and radiological aspects, particularly perpendicular calyces, interpyelocalyx space, position of calyces in relation to renal border, classification of the renal collecting system, infundibular diameter and the angle between the lower infundibulum and renal pelvis. CONCLUSION: The knowledge of intra-renal collecting system divisions and variations as the angle between the renal pelvis and lower infundibula, position of the calices in relationship with renal edge and the diameter and position of the calyces are important for the planning of minimally invasive renal surgeries.

Morphometric study applied to testicular and epididymis hydatids torsion.

Twisted testicular appendages had difficult differential diagnosis with testicular torsion. The objective of this paper is to evaluate the number, shape, size and determine the laterality pattern of the testicular and epididymal hydatids and evaluate the correlations between the length and width of the testicular and epididymal hydatids with testicular measurements. We analyzed 60 fixed cadavers and 16 patients with prostate cancer without previous hormonal treatment undergoing bilateral orchiectomy, totalizing 76 units and 152 testicles. In relation to the testicular appendices, we analyzed the following situations: absence of testicular and epididymis appendages, presence of a testicular appendix, presence of epididymis appendix, and presence of testicular and epididymis appendix. We measured the length, width and thickness of the testis and classified the appendages as sessile or pedicled. Chi-square test was used to verify associations between categorical variables. McNemar Test was used to verify differences between the percentages of right and left appendages. Correlations between quantitative measures were evaluated using the Pearson Correlation Coefficient (p < 0.05). In 50 cases (65.78%) we observed the presence of some type of appendices, in 34 cases (44.72%) we observed the presence of testicular appendices and in 19 cases (25%) the presence of epididymal appendices. We observed the presence of pedicled appendices in 39 cases (51.32%), with 25 of the cases (32.89%) of pedicled testicular appendices and 14 of the cases (18.42%) of pedicled epididymal appendages, with a significant association between the occurrence of appendices on the right and left sides (p < 0.001). Testicular hydatids were present in around two thirds of our sample being pedunculated in almost half of the cases with bilateral similarity. There is a significant chance in cases of twisted appendices that the same anatomical characteristics are present on the opposite side, which is a factor that tends to indicate the need for contralateral surgical exploration in cases of torsion, however studies with larger samples are needed to confirm these findings.

A randomised controlled trial assessing the effects of weather sensitivity profile and walking in nature on the psychophysiological response to stress in individuals with coronary artery disease. A study protocol.

BACKGROUND: The following protocol pertains to a pioneer study, aiming to investigate how weather sensitivity and walking in different environments affects the psychophysiological responses to the stress of individuals with coronary artery disease (CAD) during rehabilitation (WE_SENSE_THE_NATURE). This randomised control trial will provide fresh insight on the influence of the environmental exposure in CAD patients, as it is seldom investigated in association to the disease. Additionally, findings on the link between personality traits and cognitive functions (especially cognitive flexibility), and weather sensitivity may help reveal a fine-grained perspective on the treatment possibilities for individuals with CAD at risk to stress-vulnerability. METHODS: The proposed protocol is for a randomised control trial among individuals attending a cardiac rehabilitation program. We aim to recruit 164 individuals, collecting information related to demographic characteristics, weather sensitivity, functional capacity, personality traits, subjective mental health status, cognitive function, and basal cortisol level of participating individuals. Basal cortisol level refers to cortisol concentration in saliva and will be tested in the morning and the afternoon prior to the day of the experiment. After baseline measurements, the patients will be randomly assigned to either walking outdoors or walking indoors. All measures and their sequential order will remain the same within each group, while the treatment condition (i.e., walking environment) will vary between groups. On the day of the experiment, hemodynamic parameters (assessed via 6-hour blood pressure measurements), stress level (consisting of assessments of cortisol level), and mood (assessed using visual analogues scale) will be registered. Cold stress test will be administered to evaluate the effect of walking in different environments. DISCUSSION: The outcomes of this study may have direct clinical applications for the use of different types of exercise environments in cardiac rehabilitation programs. Awareness about the potential influence of weather sensitivity on the psychophysiological reactions to stress in individuals with CAD may contribute to a timely planning and implementation of actions leading to improved medical care services and preventive measures, especially considering the expected weather oscillations and extreme weather events due to unfolding of the climate change. TRIAL REGISTRATION: This protocol has been retrospectively registered in ClinicalTrials.gov with identifier code: NCT06139705 on November 20, 2023.

Perspectives of adult patients with mental health disorders on the relationship with nurses: a focus group study.

BACKGROUND: The relationship between the nurse and the patient with mental health disorder is crucial to the recovery process. Thus, patients with mental health disorders should be active subjects in this relationship by having autonomy and self-determination. METHODS: This study aimed to explore the perspectives of adult patients with mental health disorders on the relationship with nurses. A qualitative, descriptive, and exploratory study was conducted in March 2023, using focus group meetings in an association to support patients with severe mental health disorders in the Northern region of Portugal. The study followed the Consolidated Criteria for Reporting Qualitative Research (COREQ). A total of 8 patients participated in the study. Two focus group meetings were conducted. The inductive method was used, and content analysis of the transcripts was performed. The QDA Miner Lite 4.0 and Microsoft Excel were used for content analysis. RESULTS: Participants considered the relationship with nurses important for their recovery and expected nurses to provide support and help, being able to identify their needs, thus personalising their care. Attitudinal and communication aspects were also considered crucial for establishing a solid, trusting, and meaningful relationship. CONCLUSION: According to the findings nursing care is expected to focus on the patient, his/her preferences, expectations, and the uniqueness of each individual. The results of this study may be useful for the reflection and improvement of nurses in their relational and communication skills and the driving force for nursing students' awareness of the perspective of the relationship with patients with mental health disorder and its relevance.

Hyperfunctioning papillary thyroid carcinoma - a case report and literature review.

BACKGROUND: Malignant hyperfunctioning thyroid nodules are rare and more likely to occur in follicular cancer types rather than papillary variants. The authors present a case of a papillary thyroid carcinoma associated with a hyperfunctioning nodule. METHODS: A single adult patient submitted to total thyroidectomy with the presence of thyroid carcinoma within hyperfunctioning nodules was selected. Additionally, brief literature was conducted. RESULTS: An asymptomatic 58-year-old male was subjected to routine blood analysis and a TSH level of <0.003 mIU/L was found. Ultrasonography revealed a 21 mm solid, hypoechoic, and heterogenous nodule with microcalcifications in the right lobe. A fine needle aspiration guided by ultrasound resulted in a follicular lesion of undetermined significance. A 99mTc thyroid scintigram was followed and identified a right-sided hyperfunctioning nodule. Another cytology was performed and a papillary thyroid carcinoma was derived as a result. The patient underwent a total thyroidectomy. Postoperative histology confirmed the diagnosis and a tumor-free margin with no vascular or capsular invasions. CONCLUSION: Hyperfunctioning malignant nodules are a rare association, although a careful approach should be led since major clinical implications arise. Selective fine needle aspiration in all suspicious ≥1 cm nodules should be considered.

Lung ultrasound and diuretic therapy in chronic heart failure: a randomised trial.

BACKGROUND: Lung congestion is frequent in heart failure (HF) and is associated with symptoms and poor prognosis. Lung ultrasound (LUS) identification of B-lines may help refining congestion assessment on top of usual care. Three small trials comparing LUS-guided therapy to usual care in HF suggested that LUS-guided therapy could reduce urgent HF visits. However, to our knowledge, the usefulness of LUS in influencing loop diuretic dose adjustment in ambulatory chronic HF has not been studied. AIMS: To study whether to show or not LUS results to the HF assistant physician would change loop diuretic adjustments in "stable" chronic ambulatory HF patients. METHODS: Prospective randomised single-blinded trial comparing two strategies: (1) open 8-zone LUS with B-line results available to clinicians, or (2) blind LUS. The primary outcome was change in loop diuretic dose (up- or down-titration). RESULTS: A total of 139 patients entered the trial, 70 were randomised to blind LUS and 69 to open LUS. The median (percentile25-75) age was 72 (63-82) years, 82 (62%) were men, and the median LVEF was 39 (31-51) %. Randomisation groups were well balanced. Furosemide dose changes (up- and down-titration) were more frequent among patients in whom LUS results were open to the assistant physician: 13 (18.6%) in blind LUS vs. 22 (31.9%) in open LUS, OR 2.55, 95%CI 1.07-6.06. Furosemide dose changes (up- and down-titration) were more frequent and correlated significantly with the number of B-lines when LUS results were open (Rho = 0.30, P = 0.014), but not when LUS results were blinded (Rho = 0.19, P = 0.13). Compared to blind LUS, when LUS results were open, clinicians were more likely to up-titrate furosemide dose if the result "presence of pulmonary congestion" was identified and more likely to decrease furosemide dose in the case of an "absence of pulmonary congestion" result. The risk of HF events or cardiovascular death did not differ by randomisation group: 8 (11.4%) in blind LUS vs. 8 (11.6%) in open LUS. CONCLUSIONS: Showing the results of LUS B-lines to assistant physicians allowed more frequent loop diuretic changes (both up- and down-titration), which suggests that LUS may be used to tailor diuretic therapy to each patient congestion status.

Exercise Training Benefits Health-Related Quality of Life and Functional Capacity during Breast Cancer Chemotherapy: A Randomized Controlled Trial.

PURPOSE: To examine the effectiveness of a supervised exercise training program (SETP) on health-related quality of life (HRQoL) and functional capacity in women with breast cancer (BC) undergoing chemotherapy. METHODS: Ninety-three women with early-stage BC were randomly allocated to a SETP plus usual care (exercise, n = 47) or usual care alone (UC, n = 46). The SETP included three sessions per week, combining aerobic and resistance training, conducted concurrently over the chemotherapy. The EORTC Cancer Quality-of-Life-Questionnaire-Core-30 (QLQ-C30) and the BC-specific module (QLQ-BR23) were used to assess HRQoL. Functional capacity was analyzed by maximum voluntary handgrip strength (MVHS) and by the 30-s chair sit-to-stand test (30-s CST). These endpoints were assessed at baseline (t0); middle (t1; after 8 or 12 wk of t0); and at the end of chemotherapy (t2; after 20 wk of t0). Mean changes from baseline were assessed by an intention-to-treat approach. RESULTS: Mixed linear model analyses showed that Exercise group experienced less deterioration in several domains of QLQ-C30 at t2, including in global health status/QoL (Δ = 9.39 units; P = 0.034), QLQ-C30 summary score (Δ = 8.08 units; P < 0.001), physical (Δ = 15.14 units; P < 0.001), role ( Δ = 21.81 units; P < 0.001), cognitive (Δ = 9.16 units; P = 0.032) and social functioning (Δ = 11.67 units; P = 0.038), compared with the UC group. Similarly, Exercise group exhibited significant lower levels of fatigue (Δ = -20.19 units; P < 0.001) and appetite loss (Δ = -13.69 units; P = 0.034), compared with the UC group. Significant between-group differences were observed on MVHS of the tumor/surgery upper limb side (Δ = 2.64 kg; P < 0.001) and contralateral limb (Δ = 2.22 kg; P < 0.001), and on the 30-s CST score (Δ = 3.56repetitions; P < 0.001), favoring the Exercise group. No differences were observed on QLQ-BR23 domains. CONCLUSIONS: Exercise training was an effective complementary therapy to prevent the deterioration of HRQoL and functional capacity during chemotherapy in women with early-stage BC.

Prognostic value of flow-status in severe aortic stenosis patients undergoing percutaneous intervention.

PURPOSE: Low-flow status is a mortality predictor in severe aortic stenosis (SAS) patients, including after transcatheter aortic valve implantation (TAVI) treatment. However, the best parameter to assess flow is unknown. Recent studies suggest that transaortic flow rate (FR) is superior to currently used stroke volume index (SVi) in defining low-flow states. Therefore, we aimed to evaluate the prognostic value of FR and SVi in patients undergoing TAVI. METHODS: A single-centre retrospective analysis of all consecutive patients treated with TAVI for SAS between 2011 and 2019 was conducted. Low-FR was defined as < 200 mL/s and low-SVi as < 35 mL/m2. Primary endpoint was all-cause five-year mortality, analyzed using Kaplan-Meier curves and Cox regression models. Secondary endpoint was variation of NYHA functional class six months after procedure. Patients were further stratified according to ejection fraction (EF < 50%). RESULTS: Of 489 cases, 59.5% were low-FR, and 43.1% low-SVi. Low-flow patients had superior surgical risk, worse renal function, and had a higher prevalence of coronary artery disease. Low-FR was associated with mortality (hazard ratio 1.36, p = 0.041), but not after adjustment to EuroSCORE II. Normal-SVi was not associated with survival, despite a significative p-trend for its continuous value. No associations were found for flow-status and NYHA recovery. When stratifying according to preserved and reduced EF, both FR and SVi did not predict all-cause mortality. CONCLUSION: In patients with SAS undergoing TAVI, a low-FR state was associated with higher mortality, as well as SVi, but not at a 35 mL/m2 cut off.

Effects of chronic restraint stress in the prostate of prepubertal and adult rats.

PURPOSE: To investigate the effects of chronic stress in the prostate of prepubertal and adult rats. METHODS: Thirty-two male rats were assigned into four groups depending on the type of treatment (control or stressed) and the age at which stress was initiated (prepubertal or adult). Restraint stress stimuli were applied for six weeks. Stressed prepubertal and adult rats evaluated immediately after the last stress stimuli were named SP and SA groups, respectively. Age-matched rats were used as control groups (CP and CA). At the end of the experiment, the rats were euthanized, and prostate morphological parameters were evaluated and statistically compared. RESULTS: Application of stress stimuli to the SP group resulted in reduced body weight, but no prostate morphological modification was noted. The SA group showed reduced testosterone level and prostatic epithelium surface density, in comparison to CA group. Further, the prostatic lumen surface density was increased in adult stressed animals, in comparison to adult controls. CONCLUSIONS: The stress stimuli promoted changes in hormonal and morphological parameters in the prostate of adult stressed rats. Prepubertal stressed animals did not presented modifications of prostate morphology.

Abdominal testicular vessel distribution in human fetuses - basis for Fowler-Stephens surgery

ABSTRACT Purpose: To analyze the histology and distribution of abdominal testicular vessels in human fetuses Patients and Methods: We studied 19 fetuses (34 testes) ranging in age from 12 to 19 weeks post-conception. The fetuses were evaluated regarding crown-rump length (CRL), total length (TL) and body weight immediately before dissection. Each testis was dissected and embedded in paraffin, from which 5 µm thick sections were obtained and stained with Masson's trichrome and Anti-CD31 antibody to quantify the vessels. The stereological analysis was carried out with the Image Pro and Image J programs, using a grid to determine volumetric densities (Vv). Means were statistically compared using the unpaired T-test (p<0.05). Results: The fetuses presented mean weight of 222.5g, mean CRL of 15.3 cm and mean TL of 23.2 cm. All testes were in the abdominal position. The mean percentage of vessels (Vv) in the upper portion of the testis was 7.6% (4.6 to 15%) and in the lower portion the mean was 5.11% (2.3 to 9.8%), with a significant difference (p=0.0001). In the analysis between the upper portion of the right and left testes (p=0.99) and in the analysis of the lower portion of the right and left testes (p=0.83), we did not observe significant differences. Conclusion: The upper portion of the abdominal testis in human fetuses had a higher concentration of vessels than the lower portion. These results suggest that manipulation of the lower end of the testis during Fowler-Stephens surgery should be avoided in order to preserve the collateral circulation.

Translation, Adaptation, and Validation of the Cultural Competence Assessment in Portuguese Nurses.

Background and Purpose: Previous research shows significant benefits resulting from improving culturally competent nursing care. Thus, the purpose of this study was to translate, adapt, and validate the Cultural Competence Assessment (CCA) in a sample of Portuguese nurses. Methods: A psychometric study of the CCA, after translation into European Portuguese, was performed with a snowball sample of 284 nurses. Participants were asked to fill in a sociodemographic questionnaire and the CCA. Results: The four-factor model of the CCA (Portuguese version) exhibited satisfactory indices of fitness without item nine. Cronbach's alpha was 0.85. Correlations between subscales and the total score scale were strong and statistically significant. Conclusions: These data add to the cultural competence knowledge of nurses to promote better practices and culturally competent care.

Sixty years of the Bruce protocol: reappraising the contemporary role of exercise stress testing with electrocardiographic monitoring.

The cardiovascular response to exercise has long been a focus of interest. Over a century ago, the first descriptions of electrocardiographic changes occurring during exercise highlighted the possible relevance of this dynamic assessment. In this background, the inception of the Bruce protocol circa 60 years ago allowed for a major leap in this field by providing a standardized framework with which to address this issue, by means of an integrated and structured methodology. Since then, exercise stress testing with electrocardiographic monitoring (ExECG) has become one of the most widely appraised tests in cardiovascular medicine. Notably, past few decades have been profoundly marked by substantial advances in the approach to cardiovascular disease, challenging prior notions concerning both its physiopathology and overall management. Among these, the ever-evolving presentations of cardiovascular disease coupled with the development and implementation of several novel diagnostic modalities (both invasive and noninvasive) has led to a shifting paradigm in the application of ExECG. This technique, however, has continuously shown to be of added value across various momentums of the cardiovascular continuum, as depicted in several contemporary guidelines. This review provides a pragmatical reflexion on the development of ExECG, presenting a comprehensive overview concerning the current role of this modality, its challenges, and its future perspectives.

Validating a measure for eco-anxiety in Portuguese young adults and exploring its associations with environmental action.

BACKGROUND: Worsening environmental conditions may amplify people's emotional responses to an environmental crisis (eco-anxiety). In Portugal, young people seem to be especially concerned about climate change. However, this phenomenon needs to be interpreted using accurate instruments. Thus, this study aimed to validate the Portuguese version of the Hogg Eco-Anxiety Scale (HEAS) in young adults and examine the associations among eco-anxiety, sociodemographic characteristics, and pro-environmental behaviours. METHODS: A survey was administered to 623 Portuguese university students aged between 18 and 25 years. The survey included our Portuguese translation of the HEAS (obtained through a back-translation and pretesting process), a sociodemographic assessment, and questions related to pro-environmental behaviours. Confirmatory factor analysis was conducted to assess the construct validity of the Portuguese version of the HEAS, and global fit indices were used to assess whether the original four-dimensional structure of the scale was reproduced. The reliability of the Portuguese version of the HEAS was evaluated by Cronbach's alpha and the intraclass correlation coefficient. Measurement invariance examined sex differences in scale interpretation. Linear regressions were used to detect whether sociodemographic variables predict eco-anxiety and whether eco-anxiety predicts pro-environmental behaviours. RESULTS: The factorial structure of the original scale was replicated in the Portuguese version of the HEAS, showing good internal consistency, reliability over time and strict invariance between men and women. A higher paternal education level predicted greater eco-anxiety in children. Two dimensions of eco-anxiety-namely, rumination and anxiety about personal impacts on the environment-predicted higher engagement in pro-environmental behaviours. CONCLUSIONS: The translated scale is an appropriate tool to measure eco-anxiety in the Portuguese context and should be used to collect evidence to drive environmental and health policies. An individual's education level should be considered a determinant of their emotional response to environmental conditions. Importantly, eco-anxiety can act as a protective emotional response to preserving the planet.
