RESUMEN
OBJECTIVE: to analyze the psychometric properties of the Incivility in Nursing Education - Revised Survey - Brazilian version with undergraduate nursing students. METHOD: methodological study conducted in a nursing school in São Paulo state. It is the analysis of the psychometric properties (reliability and construct validity) of the items in the INE-R survey - Brazilian version. Construct validity was performed by Confirmatory Factor Analysis, and reliability by test-retest in order to verify the instrument's stability, as calculated by the Intraclass Correlation Coefficient and the Internal Consistency of the items according to Cronbach's alpha, ordinal alpha and McDonalds's omega coefficients. RESULTS: Confirmatory Factor Analysis fitted the proposed model with two factors (low and high incivility), with a suggestion to exclude one of student items. Most of the fitting values for the student items and all of the faculty-member items complied with the references established in the literature; the values for Internal Consistency Coefficients were greater than 0.80, and Intraclasss Correlation Coefficients were greater than 0.75. CONCLUSION: the Brazilian version of the Incivility in Nursing Education - Revised Survey is validated for the studied context, as it has shown satisfactory reliability and validity by means of factor analysis, which has confirmed the original two-factor model, with 23 items addressing student behaviors and 24 items applied to faculty behaviors. HIGHLIGHTS: (1) Incivility is a global and growing phenomenon in higher education.(2) An uncivil environment interferes with learning and health indicators.(3) A validated survey to measure incivility in nursing education is presented.

OBJECTIVE: Most women experience weight gain during the menopausal transition, often attributed to behavioral factors. Nevertheless, some women successfully maintain a healthy weight during this phase. This study aims to identify the successful cognitive and behavioral weight management strategies employed by postmenopausal women who effectively maintained a healthy weight during the menopausal transition (from premenopause to postmenopause). METHOD: Semi-structured interviews were conducted with 31 Portuguese postmenopausal women, aged 45-65 years (mean and standard deviation 54.06 ± 5.51) who successfully maintained a healthy weight (body mass index: 18.5 kg/m2-24.9 kg/m2) during the menopausal transition. The interviews were conducted via telephone (n = 29) and Zoom (n = 2), based on the participant's preference, and ranged from 11 to 52 min (22.06 ± 9.95). Using MAXQDA software, deductive-dominant content analysis of the interviews was performed. The Interface of R for the Multidimensional Analyses of Texts and Questionnaire software was used for lexical analysis. RESULTS: The qualitative analysis of cognitive and behavioral strategies for successful weight management yielded 17 categories and 37 sub-categories. Effective cognitive and behavioral strategies (e.g., planning content, stimulus control, support: help from others) were identified, mostly aligning with the Oxford Food and Activity Behaviors Taxonomy. Five new categories emerged: dietary choices, intuitive eating, food literacy, psychological self-care, and effortful inhibition. CONCLUSION: Knowing effective cognitive and behavioral weight management strategies for menopausal women is relevant, especially considering their status as a high-risk group. This knowledge provides a valuable guide for designing weight management interventions, emphasizing the essential role of behavioral change.

AIM: Understanding vaccine hesitancy, as a critical concern for public health, cannot occur without the use of validated measures applicable and relevant to the samples they are assessing. The current study aimed to validate the Vaccine Hesitancy Scale (VHS) and to investigate the predictors of children's vaccine hesitancy among parents from Australia, China, Iran, and Turkey. To ensure the high quality of the present observational study the STROBE checklist was utilized. DESIGN: A cross-sectional study. METHOD: In total, 6,073 parent participants completed the web-based survey between 8 August 2021 and 1 October 2021. The content and construct validity of the Vaccine Hesitancy Scale was assessed. Cronbach's alpha and McDonald's omega were used to assess the scale's internal consistency, composite reliability (C.R.) and maximal reliability (MaxR) were used to assess the construct reliability. Multiple linear regression was used to predict parental vaccine hesitancy from gender, social media activity, and perceived financial well-being. RESULTS: The results found that the VHS had a two-factor structure (i.e., lack of confidence and risk) and a total of 9 items. The measure showed metric invariance across four very different countries/cultures, showed evidence of good reliability, and showed evidence of validity. As expected, analyses indicated that parental vaccine hesitancy was higher in people who identify as female, more affluent, and more active on social media. CONCLUSIONS: The present research marks one of the first studies to evaluate vaccine hesitancy in multiple countries that demonstrated VHS validity and reliability. Findings from this study have implications for future research examining vaccine hesitancy and vaccine-preventable diseases and community health nurses.

Hemodialysis is a conservative treatment for end-stage renal disease. It has various complications which negatively affect quality of life (QOL). This study aimed to examine the relationship between fatigue, pruritus, and thirst distress (TD) with QOL of patients receiving hemodialysis, while also considering the mediating role of treatment adherence (TA). This cross-sectional study was carried out in 2023 on 411 patients receiving hemodialysis. Participants were consecutively recruited from several dialysis centers in Iran. Data were collected using a demographic information form, the Fatigue Assessment Scale, the Thirst Distress Scale, the Pruritus Severity Scale, the 12-Item Short Form Health Survey, and the modified version of the Greek Simplified Medication Adherence Questionnaire for Hemodialysis Patients. Covariance-based structural equation modeling was used for data analysis. The structural model and hypothesis testing results showed that all hypotheses were supported in this study. QOL had a significant inverse association with fatigue, pruritus, and TD and a significant positive association with TA. TA partially mediated the association of QOL with fatigue, pruritus, and TD, denoting that it helped counteract the negative association of these complications on QOL. This model explained 68.5% of the total variance of QOL. Fatigue, pruritus, and TD have a negative association with QOL among patients receiving hemodialysis, while TA reduces these negative associations. Therefore, TA is greatly important to manage the associations of these complications and improve patient outcomes. Healthcare providers need to assign high priority to TA improvement among these patients to reduce their fatigue, pruritus, and TD and improve their QOL. Further studies are necessary to determine the most effective strategies for improving TA and reducing the burden of complications in this patient population.

Vulnerability to heat waves and their negative effects on health vary not only due to individual factors but also due to situational factors, such as time and geography. Hence, we explored seasonal variations and predictors of heat wave feelings of threat across different heat wave geographical susceptibility locations in Portugal. A total of 238 Portuguese residents responded to a web-based longitudinal survey: before the summer, during a heat wave in the summer, during the summer, and after the summer. Geographical location was used as an indicator of risk exposure, operationalized as heat wave occurrence susceptibility (low, moderate, high). Heat wave demands and resources perceptions were assessed to compute an indicator of heat wave feelings of threat. During the heat wave, feelings of threat were higher among participants in high-susceptibility locations, with demands outweighing resources perceptions, suggesting greater distress and coping difficulty. Regression analysis suggested that older participants and female participants living in moderate-high-susceptibility locations had greater difficulty in recovering. Heat wave risk perception and positive affect about heat were identified as the most consistent predictors of heat wave feelings of threat, with risk perception increasing and positive affect decreasing such feelings. Participants with (individual and geographical) vulnerability profiles, who had greater difficulty in coping and recovering from heat waves, could benefit from resource-building/enhancing interventions. In a climatic crisis context, monitoring psychological responses to heat waves (e.g., threat) may enable anticipated action to build resilience before, rather than after, the effects become damaging to physical and psychological health.
RESUMEN
OBJECTIVES: to verify the contribution of mothers' oral health impact profile to their children's oral health profile and the contribution of mothers' well-being and the caries index (dmft) to children's well-being. METHODS: This is a cross-sectional observational study. Mothers and pre-school children enrolled in public schools in the municipality of Araraquara-SP took part. The Oral Health Impact Profile Questionnaire (OHIP-14), Satisfaction with Life Scale (SWLS), Early Childhood Oral Health Impact Scale (ECOHIS) and the Autoquestionnaire Qualité de Vie Enfant Imagé (AUQEI) were used. To diagnose caries, a clinical examination was carried out to calculate the dmft index. Path analysis was carried out and the path coefficients were estimated (ß) and evaluated using the z-test (α = 5%). RESULTS: 443 children took part (5.19 ± 0.64 years; 52.4% boys) with an mean dmft of 1.31 ± 2.19. The mean age of the mothers was 33.4 ± 7.01 years. There was a significant impact of dmft and maternal well-being on the child's subjective well-being (s2explained = 43%). The mothers' oral health impact profile and the child's caries experience had a significant influence on both the child (OHIP: ß = 0.22; p < 0.001; dmft: ß = 0.48; p < 0.001) and the family (OHIP: ß = 0.29; p < 0.001; dmft: ß = 0.32; p < 0.001). The child's dmft (ß=-0.10; p = 0.005) and the mothers' subjective well-being (ß=-0.61; p < 0.001) had a significant impact on the child's subjective well-being. CONCLUSION: The mothers' oral health impact profile and the child's caries experience had an impact on both the child and the family. Mothers' subjective well-being and caries experience should be considered when assessing the subjective well-being of Brazilian preschool children.

Background: We compared the effects of home- vs gym-based delivery modes of two 8-week supervised multicomponent intensity training regimes on cardiorespiratory fitness and arterial stiffness in 17 adults with intellectual and developmental disability during the COVID-19 pandemic. Methods: Participants were assigned to sprint interval training or continuous aerobic training, both incorporating resistance training. The intervention started with 8-weeks of online training (M1-M2), 1-month of detraining, plus 8-weeks of gym-based training (M3-M4). Results: Peak oxygen uptake decreased from M1-M2 and increased from M2-M4. Central arterial stiffness decreased between M1-M2, and M1-M4, along with peripheral arterial stiffness. Central systolic blood pressure decreased from M1-M2 only with sprint interval training. Conclusion: Home-based training minimized the negative impact of the lockdown on central arterial stiffness and central blood pressure, but it did not match the benefits on cardiorespiratory fitness and peripheral arterial stiffness of a gym-based intervention, irrespective of the multicomponent intensity training regime. Registered in ClinicalTrials.gov NCT05701943.

RESUMEN
Exercise testing unmasks more exaggerated systolic blood pressure responses (SBP) in Black compared with White male adults. Such responses, if translatable to females, may detect racial disparities particularly relevant during menopause. Given the endothelial involvement in BP regulation and as a source of fibrinolytic markers, it follows that fibrinolytic and BP response to exercise could be linked. Thus, we examined BP and fibrinolytic responses to exercise testing in Black and White postmenopausal females. Postmenopausal females (Black = 40; White = 41; 51-70 yr) performed maximal treadmill exercise. BP and blood draws were conducted before and immediately after exercise. Plasma samples, using minimal stasis, were analyzed for tissue plasminogen activator (tPA) and plasminogen activator inhibitor 1 (PAI-1) activity and antigen, respectively. Resting SBP and fibrinolytic potential were similar between races. Black females exhibited greater increases in SBP during exercise [change (d)=75, 95% CI: 64-86 mmHg, P < 0.001] than White females (d = 60, 95% CI: 48-71 mmHg, P < 0.001). Black compared with White females had smaller changes in tPA (d = 3.27, 95% CI: 2.28-4.27 IU/mL, P < 0.001 vs. d = 5.55, 95% CI: 4.58-6.53, P < 0.001) and PAI-1 (d = -2.89, 95% CI: -4.39 to -1.40 IU/mL, P < 0.001 vs. d = -5.08, 95% CI: -6.59 to -3.61, P < 0.001) activities after exercise. SBP exercise-induced changes were not associated with tPA (r = -0.10, P = 0.42) or PAI-1 (r = 0.13, P = 0.30), without any influence of race (P > 0.05). Our findings show that maximal exercise unmasks risk factors for cardiovascular disease in Black postmenopausal females.NEW & NOTEWORTHY Exaggerated SBP responses to exercise testing are more frequent in Black than in White male adults. Such responses, if translatable to females, may detect early racial disparities arriving during menopause. Because the endothelium regulates BP and fibrinolytic responses, these could be linked during exercise. At peak exercise, Black but not White postmenopausal females had more exaggerated SPB responses regardless of reduced fibrinolytic potential. Maximal exercise unmasked risk factors for cardiovascular disease in Black postmenopausal females.

PURPOSE: We examined heart rate variability (HRV) and baroreflex sensitivity (BRS) disease- and age-related response at 10-and 60-min after an acute high-intensity interval (HIIE) and moderate continuous exercise (MICE) in older adults with and without type 2 diabetes mellitus (T2DM) and healthy young adults. METHODS: Twelve older male adults with (57-84 years) and without T2DM (57-76 years) and 12 healthy young male adults (20-40 years) completed an isocaloric acute bout of HIIE, MICE, and a non-exercise condition in a randomized order. Time and Wavelets-derived frequency domain indices of HRV and BRS were obtained in a supine position and offline over 2-min time-bins using Matlab. RESULTS: HIIE but not MICE reduced natural logarithm root mean square of successive differences (Ln-RMSSD) (d = - 0.85; 95% CI - 1.15 to - 0.55 ms, p < 0.001), Ln-high-frequency power (d = - 1.60; 95% CI - 2.24 to - 0.97 ms2; p < 0.001), and BRS (d = - 6.32; 95% CI - 9.35 to - 3.29 ms/mmHg, p < 0.001) in adults without T2DM (averaged over young and older adults without T2DM), returning to baseline 60 min into recovery. These indices remained unchanged in older adults with T2DM after HIIE and MICE. Older adults with T2DM had lower resting Ln-RMSSD and BRS than aged-matched controls (Ln-RMSSD, d = - 0.71, 95% CI - 1.16 to - 0.262 ms, p = 0.001; BRS d = - 3.83 ms/mmHg), 95% CI - 6.90 to - 0.76, p = 0.01). CONCLUSIONS: Cardiovagal modulation following acute aerobic exercise is intensity-dependent only in adults without T2DM, and appears age-independent. These findings provide evidence of cardiac autonomic impairments in older adults with T2DM at rest and following aerobic exercise.

To clarify the role of socioeconomic status (SES) in cardiovascular and cancer mortality disparities observed between Black, Hispanic, and Asian compared to White adults, we conducted a meta-analysis of the longitudinal research in the USA. A PubMed, Ovid Medline, Web of Science, and EBSCO search was performed from January 1995 to May 2023. Two authors independently screened the studies and conducted risk assessments, with conflicts resolved via consensus. Studies were required to analyze mortality data using Cox proportional hazard regression. Random-effects models were used to pool hazard ratios (HR) and reporting followed PRISMA guidelines. Twenty-two studies with cardiovascular mortality (White and Black (n = 22), Hispanic (n = 7), and Asian (n = 3) adults) and twenty-three with cancer mortality endpoints (White and Black (n = 23), Hispanic (n = 11), and Asian (n = 10) adults) were included. The meta-analytic sample for cardiovascular mortality endpoints was 6,199,049 adults (White = 4,891,735; Black = 935,002; Hispanic = 295,623; Asian = 76,689), while for cancer-specific mortality endpoints was 7,745,180 adults (White = 5,988,392; Black= 1,070,447; Hispanic= 484,848; Asian = 201,493). Median follow-up was 10 and 11 years in cohorts with cardiovascular and cancer mortality endpoints, respectively. Adjustments for SES attenuated the higher risk for cardiovascular (HR, 1.46; 95% CI, 1.30-1.64) and cancer mortality (HR, 1.35; 95% CI, 1.32-1.38) of Black compared to White adults by 25% (HR, 1.21; 95% CI, 1.15-1.28) and 19% (HR, 1.16; 95% CI, 1.13-1.18), respectively. However, the Hispanic cardiovascular (HR, 0.79; 95% CI, 0.73-0.85) and Asian cancer mortality (HR, 0.81; 95% CI, 0.76-0.86) advantage were independent of SES. These findings emphasize the need to develop strategies focused on SES to reduce cardiovascular and cancer mortality in Black adults.
RESUMEN
Background: Urinary Incontinence (UI) has numerous repercussions in women's lives, and it is underreported/underdiagnosed. Objective: The present study aimed to understand: (1) the differences between women with and without urine loss regarding Quality of Life (QoL) and Sexual Function (SF); (2) the possible moderation role of UI-related beliefs and strategies on the relationship between UI-symptom severity and SF and QoL, in women with UI. Methods: Cross-sectional Design. Participants: Primary aim: Overall, 2,578 women aged 40-65 (Mage = 49.94, DPage = 6.76) were collected online. Secondary aim: 1,538 women who self-reported having urine loss occasionally/frequently (Mage = 50.19, DPage = 6.58). All data analyses were done with IBM SPSS Statistics and R statistical system 4.0 through RStudio. Statistical Path analysis was performed with the lavaan package to study the hypothetical association and moderating effects between the variables. Results: Primary aim: women without UI had a better SF [t(2576) = 3.13, p = 0.002; 95% C.I., 0.18 to 0.80] and QoL [t(2576) = 7.71, p < 0.001; 95% C.I., 3.14 to 5.28] than their counterparts with UI. Secondary aim: UI-related coping strategies attenuated the impact of UI-symptom severity on SF(ß = -0.07; p = 0.041); the more dysfunctional the UI-related beliefs were, the poorer QoL was (ß = -0.06; p = 0.031); the more frequent the UI-related hiding/defensive strategies were, the poorer QoL was (ß = -0.26; p < 0.001). Discussion: Limitations: online data collection, which thwarted the clarification of participants, if needed; absence of a UI medical diagnosis (only self-reported measures were used). Strengths and practical implications: (i) the crucial role of UI-related beliefs and strategies in the QoL of women with UI; (ii) the impact that UI-concealing/defensive strategies have in attenuating the impact of UI-symptom severity on SF, which might be perceived as a short-term benefit and hence contribute to maintaining the UI condition and constitute a barrier to help-seeking, (iii) impact of UI-symptom severity on QoL and SF (including a comparison group entailing women without UI, which is scarcely used); and (iv) the use of gold-standard and psychometrically robust instruments. Conclusion: Changing dysfunctional UI-related beliefs and strategies in clinical settings may improve the QoL; UI-concealing strategies may reinforce themselves by immediate effects on SF, but are not functional in the long term.
RESUMEN
Introduction: Evaluating signs of anxiety related to body appearance is becoming increasingly important in contemporary society and, in this sense, the Social Appearance Anxiety Scale (SAAS) seems an interesting alternative of measurement. Objectives: To evaluate the psychometric properties of the Portuguese version of the SAAS when applied to Brazilian adults who practice physical exercise and verify the influence of individual characteristics on participants' social appearance anxiety. Methods: This was a cross-sectional study conducted online. The participants completed the SAAS and a demographic questionnaire. The psychometric properties of the SAAS one-factor model were evaluated using confirmatory factor analysis. A structural model was built for men and women to verify the influence of individual characteristics of the participants on social appearance anxiety. Results: 1,495 individuals participated in the study (70.8% women; mean age = 29.5, SD = 8.9 years). The data obtained with the SAAS presented good indicators of validity and reliability for both genders (CFI > 0.97, TLI > 0.97, SRMR = 0.04, α > 0.97, ω > 0.85). For both men and women, greater levels of social appearance anxiety were observed among younger participants, who had a higher body mass index, self-reported an eating disorder, and perceived a change in their body after the onset of the COVID-19 pandemic. For women specifically, higher income and having started physical exercise more recently were associated with greater levels of social appearance anxiety. Conclusion: The findings supported the validity and reliability of the data obtained with the SAAS and revealed that when investigating social appearance anxiety in future research and clinical protocols, specific individual characteristics should be considered.
RESUMEN
Bullying in academic settings has long-lasting implications on students' well-being and career prospects, particularly in fields like nursing that require a high level of interpersonal skills and emotional resilience. This study explored the relationships between experiences of bullying and intentions to drop out among Iranian nursing students, with major satisfaction and a sense of belonging serving as mediating factors. A cross-sectional research design was employed from April to June 2023. Undergraduate nursing students (n = 386) filled out a five-part questionnaire namely demographic and educational information, bullying behaviors in nursing education environments, the Belongingness scale, intention to drop out, and academic major satisfaction scale. The study confirmed that experiences of bullying positively correlated with intentions to drop out, negatively affected students' sense of belonging and major satisfaction, and established that course satisfaction and a sense of belonging acted as mediators between bullying and intentions to drop out. The findings show the urgent need for anti-bullying interventions targeting faculty behavior and educational strategies aimed at fostering a sense of belonging and course satisfaction among nursing students.
RESUMEN
The COVID-19 pandemic caused unprecedented changes to educational institutions, forcing their closure and a subsequent shift to online education to cater to student learning requirements. However, successful online learning depends on several factors and may also vary between countries. As such, this cross-sectional study sought to investigate how engagement of university students, a major driver of online learning, was influenced by course content, online interaction, student acceptance, and satisfaction with online learning, as well as self-efficacy across nine countries (China, India, Iran, Italy, Malaysia, Portugal, Serbia, Turkey, and the United Arab Emirates) during the COVID-19 pandemic. Using a questionnaire-based approach, data collected from 6,489 university students showed that student engagement was strongly linked to perception of the quality of the course content and online interactions (p < .001). The current study also indicated that online interactions are a major determinant of academic efficacy but only if mediated by engagement within the online learning context. A negative correlation between student engagement and satisfaction with online learning was found, demonstrating the importance of students being engaged behaviorally, emotionally, and cognitively to feel satisfied with learning. Academic efficacy and student satisfaction were explained by course content, online interaction, and online learning acceptance, being mediated by student engagement. Student satisfaction and, to a lesser degree academic efficacy, were also associated with online learning acceptance. Overall, the structural equation model was a good fit for the data collected from all nine countries (CFI = .947, TLI = .943; RMSEA = .068; SRMR = .048), despite differences in the percentage variations explained by each factor (no invariance), likely due to differences in levels of technology use, learning management systems, and the preparedness of teachers to migrate to full online instruction. Despite limitations, the results of this study highlight the most important factors affecting online learning, providing insight into potential approaches for improving student experiences in online learning environments.

Background: The concept of oral health related to quality of life involves the impact that oral health has on an individual's well-being. The Early Childhood Oral Health Impact Scale (ECOHIS) was developed to measure the impact of oral health problems on the lives of children and their families. Objective: To evaluate the psychometric properties of ECOHIS applied to mothers of preschool children and estimate the influence of demographic characteristics, caries experience, and plaque index on the ECOHIS score. Methods: The fit of ECOHIS to the data was assessed by confirmatory analysis. Chi-square for degrees of freedom ratio (χ2/df), Comparative Fit Index (CFI), Tucker-Lewis Index (TLI), and Root Mean Square Error of Approximation (RMSEA) were used. Reliability was estimated by the ordinal coefficients alpha (α) and omega (ω). The factorial invariance was estimated by the difference in CFI (ΔCFI). Comparisons of the ECOHIS mean scores according to the demographic characteristics, caries experience, and plaque index was performed using analysis of variance (ANOVA). Results: A total of 371 children participated in the study. Mothers' mean age was 33.0 (SD = 7.04) years. The ECOHIS presented a good fit to the data (χ2/df = 4.31; CFI = 0.95; TLI = 0.94; RMSEA = 0.09) and a strict model invariance. Children without caries and from higher income class had lower oral health impact. Conclusion: The data obtained with the ECOHIS were valid, reliable, and invariant. Children with caries experience and from lower income families had a greater impact of oral problems.

We examined the relationships between three eating behaviors and nine motives underlying food choices made by Brazilian adults. Using participant responses to the short version of the Three-Factor Eating Questionnaire and the Food Choice Questionnaire, we investigated eating behaviors (cognitive restriction, uncontrolled eating, and emotional eating) and motives for food choices (health, mood, convenience, sensory appeal, natural content, price, weight control, familiarity, and ethical concern). We used a structural equation model to test relationship pathways (ß), with eating behaviors as independent variables and motives for food choices as dependent variables. Participants were 1297 individuals (69.5% female) with a mean age of 25.0 years (SD = 5.8). We confirmed the validity and reliability of the questionnaires in this sample. Restrictive eating behavior was significantly related to motives of health (ß = .415), mood (ß = .127), natural content (ß = .364), weight control (ß = .681), and ethical concern (ß = .161). Emotional eating behavior was related to motives of mood (ß = .277), health (ß = -.137), and natural content (ß = -.136). Uncontrolled eating behavior was related to motives of convenience (ß = .226), sensory appeal (ß = .121), price (ß = .153), and familiarity (ß = .090). We believe these findings can now help design future research and clinical interventions for managing people's risky eating behaviors and promoting beneficial food choices.

Sex differences in resting cerebral hemodynamics decline with aging. Given that acute resistance exercise (RE) is a hypertensive challenge, it may reveal sex-dependent abnormalities in cerebral hemodynamics. Thus, we hypothesized that cerebral blood velocity and pulsatility responses to RE would be sex-dependent in older adults. Fourteen older females and 11 males (50-68 yr) completed a high-intensity unilateral isokinetic knee flexion/extension exercise. Measurements were collected at baseline, immediately, 5- and 30-min post-RE. Blood pressure was measured via finger photoplethysmography. Mean middle cerebral artery blood velocity (MCAv) and pulsatility were assessed via transcranial Doppler ultrasound. Carotid pulsatility was obtained via duplex ultrasound. MCAv increased immediately after RE in older females [mean difference (d) = 6.02, 95% CI: 1.66 to 10.39 cm/s, P < 0.001] but not in males (d = -0.72, 95% CI: -3.83 to 5.27 cm/s, P = 0.99), followed by similar reductions 5-min post-RE in older females (d = -4.40, 95% CI: -8.81 to -0.10 cm/s, P = 0.045) and males (d = -6.41, 95% CI: -11.19 to -1.62 cm/s, P = 0.003). MCAv pulsatility increased similarly in older females (d = 0.24, 95% CI: 0.11 to 0.40, P < 0.001) and males (d = 0.38, 95% CI: 0.20 to 0.53, P < 0.001), persisting 5-min post-RE. Older females showed smaller increases in carotid pulsatility immediately after RE (d = 0.18, 95% CI: 0.03 to 0.38, P = 0.01) than males (d = 0.48, 95% CI: 0.26 to 0.68, P < 0.001). An exercise-mediated hypertensive stimulus revealed differential sex responses in MCAv and carotid pulsatility but not in cerebral pulsatility. Cerebral pulsatility findings suggest a similar sex susceptibility to cerebrovascular abnormalities following exercise-mediated hypertensive stimulus in older adults.NEW & NOTEWORTHY Sex differences in resting cerebral hemodynamics decline with advancing age as females experience larger reductions in cerebral blood velocity and steeper pulsatility increases than males. However, an exercise-mediated hypertensive stimulus might reveal sex differences in cerebral hemodynamics not apparent at rest. Following high-intensity resistance exercise, older females but not males exhibit increases in cerebral blood velocity, despite similar increases in cerebral pulsatility. The susceptibility to cerebrovascular abnormalities following exercise-mediated hypertensive stimulus appears similar between sexes.

Flow-mediated slowing (FMS) is a non-invasive measure of endothelial function measured through reactive hyperemia-induced changes in pulse wave velocity (PWV). FMS is suggested to mitigate known pitfalls of flow-mediated dilation (FMD) including suboptimal repeatability and high-operator dependency. However, the few single-rater studies that examined FMS repeatability have shown controversial results and used only regional measurements of PWV, which might not reflect local brachial artery stiffness responses to reactive hyperemia. We assessed the inter- and intra-rater repeatability of ultrasound-based changes in local PWV (FMS) and diameter (FMD). Twenty-four healthy male participants aged 23-75 yr, were examined on two separate days. Reactive hyperemia-induced changes in PWV were calculated using a tailored R-script. The inter- and intra-rater repeatability were tested with the intraclass correlation coefficient (ICC), coefficient of variation (CV), and the Bland-Altman plot estimates. The inter-rater repeatability of FMS (bias: -0.08%; ICC: 0.85; 95% CI: 0.65 to 0.93; CV: 11%) and FMD (bias: -0.02%; ICC: 0.98; 95% CI: 0.97 to 0.99; CV: 7%) showed overall good repeatability over different days. The intra-rater repeatability of FMD (1st rater: bias: 0.27%; ICC: 0.90; 95% CI: 0.78 to 0.96; CV: 14%; 2nd rater: bias: 0.60%; ICC: 0.85; 95% CI: 0.64 to 0.94; CV: 18%) was better than FMS (1st rater: bias: -1.03%; ICC: 0.76; 95% CI: 0.44 to 0.91; CV: 21%; 2nd rater: bias:-0.49%; ICC: 0.70; 95% CI: 0.34 to 0.80; CV: 23%) but not different between raters. Ultrasound-based local measurements of PWV deceleration reactive hyperemia were repeatable among the raters.
