Developing technologies to assess vascular ageing: a roadmap from VascAgeNet

Vascular ageing (vascular ageing) is the deterioration of arterial structure and function which occurs naturally with age, and which can be accelerated with disease. Measurements of vascular ageing are emerging as markers of cardiovascular risk, with potential applications in disease diagnosis and prognosis, and for guiding treatments. However, vascular ageing is not yet routinely assessed in clinical practice. A key step towards this is the development of technologies to assess vascular ageing. In this Roadmap, experts discuss several aspects of this process, including: measurement technologies; the development pipeline; clinical applications; and future research directions. The Roadmap summarises the state of the art, outlines the major challenges to overcome, and identifies potential future research directions to address these challenges.

Perspectives from diverse stakeholders in a youth community-based participatory research project

INTRODUCTION

TEEN HEED (Help Educate to Eliminate Diabetes) is a community-based youth participatory action research (YPAR) study in which prediabetic adolescents from a predominantly low-income, non-white neighborhood in New York City participated in a peer-led diabetes prevention intervention. The aim of the current analysis is to evaluate the TEEN HEED program through examination of multiple stakeholder perspectives to identify strengths and areas for improvement that may inform other YPAR projects.

METHODS

We conducted 44 individual in-depth interviews with representatives from six stakeholder groups (study participants, peer leaders, study interns and coordinators, and younger and older community action board members). Interviews were recorded, transcribed, and analyzed using thematic analysis to identify overarching themes.

RESULTS

Dominant themes identified were: 1) YPAR principles and engagement, 2) Youth engagement through peer education, 3) Challenges and motivations for research participation, 4) Study improvements and sustainability, and 5) Professional and personal impacts of the study.

CONCLUSIONS

Emergent themes from this study provided insights on the value of youth participation in research and informed recommendations for future YPAR studies.

Approach to Diagnosis and Management of Hypertension: A Comprehensive and Combined Pediatric and Adult Perspective

The global prevalence of primary hypertension has been increasing both in children and in the adolescent and adult populations and can be attributed to changes in lifestyle factors with an obesity epidemic, increased salt consumption, and sedentary lifestyles. Childhood blood pressure is the strongest predictor of adult hypertension. Although hypertension in adults is associated strongly with an increased risk for cardiovascular disease, chronic kidney disease, and mortality, outcomes in children are defined less clearly. In adults, major guidelines agree on a threshold of less than 120/80 mm Hg as the optimal blood pressure (BP) and recommend a target of less than 130/80 mm Hg for treatment in most cases. In children, international pediatric guidelines recommend using thresholds based on the normative distribution of BP in healthy normal-weight children. Out-of-office BP assessment is extremely useful for confirming the diagnosis of hypertension and monitoring response to treatment. Lifestyle modifications are instrumental whether coupled or not with pharmacologic management. New agents such as nonsteroidal mineralocorticoid-receptor antagonists, aminopeptidase A inhibitors, aldosterone synthase inhibitors, and dual endothelin antagonists hold significant promise for resistant hypertension. The transition from pediatric to adult care can be challenging and requires careful planning and effective coordination within a multidisciplinary team that includes patients and their families, and pediatric and adult providers.

Changes in general and abdominal obesity in children at 4, 6 and 9 years of age and their association with other cardiometabolic risk factors

Temporary changes in childhood obesity and their association with cardiometabolic risk factors have been receiving increased attention. The objective of this study was to evaluate changes in general (GO) and abdominal (AO) obesity in children from 4 to 9 years of age and their associations with cardiometabolic risk factors at 9 years of age. This study includes 1344 children from the Longitudinal Childhood Obesity Study (ELOIN). Physical examinations performed at 4, 6 and 9 years of age and a blood sample was only taken at 9 years of age. Changes in obesity from 4 to 9 years of age were estimated using Body Mass Index and waist circumference. Participants were classified into four groups according to GO and AO: (1) stable without obesity (no obesity at all three measurements); (2) remitting obesity at 9 years (obesity at 4 and/or 6 years but not at 9 years); (3) incident or recurrent obesity at 9 years (obesity only at 9 years, at 4 and 9 years or at 6 and 9 years); and (4) stable or persistent with obesity (obesity at 4, 6 and 9 years). Dyslipidemia and dysglycemia were defined by the presence of at least one altered parameter of the lipid or glycemic profile. Odds ratios (OR) were estimated using logistic regression. Compared with children without GO at all ages, those with persistent GO had an OR of 3.66 (95% CI: 2.06-6.51) for dyslipidemia, 10.61 (95% CI: 5.69-19.79) for dysglycemia and 8.35 (95% CI: 4.55-15.30) for high blood pressure. The associations were fairly similar in the case of AO, with ORs of 3.52 (95% CI: 1.96-6.34), 17.15 (95% CI: 9.09-32.34) and 8.22 (95% CI: 4.46-15.15), respectively, when comparing persistent versus stable without AO. Children with incident obesity at 9 years presented a moderate cardiometabolic risk that was nevertheless higher compared to those stable without obesity, whereas those with remitting obesity did not show any significant associations.

CONCLUSION

Incident, and especially, persistent obesity, is associated with an increased cardiometabolic risk. The very early prevention of obesity, with a focus on nutrition, physical activity and sedentary behaviour, as well as tracking growth from birth to age 5, should be a priority to prevent the burden of cardiometabolic disease with consequences for adulthood.

WHAT IS KNOWN

• General and abdominal obesity has been shown to be associated with other cardiometabolic risk factors such as dyslipidemia, insulin resistance and hypertension. • Temporary changes in obesity and their associations with cardiometabolic risk factors have not been sufficiently explored in childhood.

WHAT IS NEW

• Children with incident, and especially persistent, general and/or abdominal obesity, had an increased risk of dyslipidemia, dysglycemia and high blood pressure. •Remitting obesity was not associated with an increased cardiometabolic risk.

Comparisons of tri-ponderal mass index and body mass index in discriminating hypertension at three separate visits in adolescents: A retrospective cohort study

OBJECTIVE

To estimate whether the new obesity indicator tri-ponderal mass index (TMI) has a better capacity to predict adolescent hypertension (HTN) and HTN subtypes at three separate blood pressure (BP) visits than the conventionally used body mass index (BMI).

METHODS

A total of 36,950 adolescents who had initial normal BP from 2012 to 2019 were included in Suzhou, China. HTN was defined as having three separate visits of elevated BP in 2020. The area under the receiver-operating characteristic curve (AUC), false-positive rate, false-negative rate, total misclassification rates, net reclassification improvement (NRI), and integrated discrimination improvement were calculated to compare the discriminative ability of HTN between BMI and TMI.

RESULTS

TMI had better predictive abilities than BMI among all of the participants when predicting HTN (difference in AUC = 0.019, 95% CI = 0.007-0.031; NRI = 0.067, 95% CI = 0.008-0.127) and isolated systolic hypertension (difference in AUC = 0.021, 95% CI = 0.005-0.036; NRI = 0.106, 95% CI = 0.029-0.183). The difference in prediction abilities between BMI and TMI was more obvious in the subgroup of age ≥16. Also, TMI outperformed BMI in predicting adolescent HTN in girls but not in boys.

CONCLUSION

Compared with BMI, TMI may have a better predictive capacity for HTN, particularly in girls and older adolescents. TMI has the potential to be used as an effective predictor for HTN in clinic practice. Further studies are needed to verify the utility of TMI.

Early Signs of Microvascular Endothelial Dysfunction in Adolescents with Newly Diagnosed Essential Hypertension

Endothelial dysfunction represents one of the key pathomechanisms in many diseases, including hypertension. Peripheral arterial tonometry (PAT) evaluates the functional status of microvascular endothelium and offers a biomarker of early, potentially reversible, vascular damage. This study aimed to assess endothelial function using conventional and novel indices of PAT in pediatric hypertensives. As such, 100 adolescents with normal blood pressure, and essential and white-coat hypertension were examined using EndoPAT 2000. Conventional reactive hyperemia index (RHI) and novel indices of hyperemic response, including the area under the curve of hyperemic response (AUC), were evaluated. AUC was the only parameter sensitive to the effect of hypertension, with significantly lower values in essential hypertensives compared to normotensives and white-coat hypertensives (p = 0.024, p = 0.032, respectively). AUC was the only parameter significantly correlating with mean ambulatory monitored blood pressure (r = −0.231, p = 0.021). AUC showed a significant negative association with age (p = 0.039), but a significant positive association with pubertal status indexed by plasma levels of dehydroepiandrosterone (p = 0.027). This is the first study reporting early signs of microvascular endothelial dysfunction evaluated using PAT in adolescents with newly diagnosed essential hypertension. Detailed analysis of hyperemic response using overall magnitude indexed by AUC provided a more robust method compared to the conventional evaluation of RHI.

Development and validation of the Distracting Ingenuity Promotion Scale for paediatric nurses to support the psychological outcomes of paediatric patients and their families: A survey-based cross-sectional cohort study

Aim

To develop and validate the Distracting Ingenuity Promotion Scale (DIPS) for paediatric nurses.

Design

Cross‐sectional study using anonymized self‐administered questionnaires.

Methods

From July–November 2013, paediatric nurses working in the wards or outpatient departments in 39 medical institutions in Japan were enrolled in the survey. Data were analysed using the Student's t‐test, Mann–Whitney U test and analysis of variance test. Exploratory and confirmatory factor analyses were performed to validate the factors in the DIPS. Cronbach's α was used to calculate the reliability of the DIPS.

Results

The DIPS included five subscales comprising 21 items. The goodness‐of‐fit indices for confirmatory factor analysis had a Comparative Fit Index of 0.923 and a Root Mean Square Error of Approximation of 0.059 and fulfilled the standard external validity criteria. Cronbach's α was 0.707–0.826 for each subscale and 0.895 for the overall scale.

Incidence and correlates of high blood pressure from childhood to adulthood: the Birth to Twenty study

BACKGROUND

There is growing evidence from high-income countries suggesting that hypertension developed in childhood and adolescence persists into adulthood. The objective of this study was to investigate the incidence and risk factors of high blood pressure (BP) in urban black children.

METHODS

We used data from the Birth to Twenty (BT20+) cohort in Johannesburg, South Africa constituting of children born in 1990 and who had their growth, development and blood pressure measured at six follow-up periods over the course of 13 years. High BP was classified as at least 95th percentile for age, sex and height. Incidence rate of high BP was calculated using survival analysis and risk factors were determined by use of Cox proportional hazard regression.

RESULTS

Over a follow-up period of 13 years, the overall incidence rate of high BP was 57 cases per 1000 person-years (95% CI 53.2-61.1). Risk for incident high BP increased with rapid relative weight gain in early childhood (hazard ratio =1.11, 95% CI 1.00-1.22), mid-childhood (hazard ratio = 1.13, 95% CI 1.03-1.24) and adolescence (hazard ratio = 1.21, 95% CI 0.99-1.47). Maternal parity significantly increased the risk for incident high BP (hazard ratio = 1.08, 95% CI 1.01-1.15).

CONCLUSION

Maternal parity and relative weight gain were determinants for incident high blood pressure in urban black South African children and adolescents. To reduce the high incidence and the disease burden of high BP, national programs should focus on promoting healthy lifestyle in early stages of life to prevent rapid weight gain and later cardiovascular disease risk. Further research is required to investigate whether incident high BP in childhood predict clinical outcomes in adulthood.

Fear, changes in routine and dental care for children and adolescents with autism spectrum disorder in the COVID-19 pandemic: A survey with Brazilian parents

AIMS

This study aimed to report the perception of parents of children/adolescents with autism regarding the parents' fear of the pandemic by COVID-19. Also, to report children's fear about the use of individual protective equipment (IPE) in dental appointments, and the impact on the daily routine during the pandemic.

METHODS AND RESULTS

A cross-sectional study through an open online survey was addressed to parents of children/adolescents autistic, aged between 3 and 18 years. The questionnaire had questions regarding the parents' fear of the COVID-19 pandemic, the parents' perception about the children/adolescents' fear of the use of IPEs at dental care, and the impact of the daily routine during the pandemic and social impact after the pandemic. Parents' reports on the degree of ASD (mild, moderate, and severe) of the child/adolescent. A total of 1001 responses were obtained. 50.35% of parents had high fear of the pandemic by COVID-19, 59.34% believe that children/teenagers will be afraid of the dentist's IPE and 61.64% responded that the COVID-19 pandemic had a high impact on the daily routine of children/adolescents with ASD.

CONCLUSIONS

Most parents reported fear of the pandemic by COVID-19, that children/adolescents with autism may be afraid of IPE and had a high impact on their daily routine during the pandemic.

The pressure's on: understanding neurocognitive and psychological associations with pediatric hypertension to inform comprehensive care

The prevalence of hypertension is increasing in pediatric populations. While clinical data and practice guidelines identify the impact of hypertension on organ dysfunction and emphasize the importance for end-organ damage screening, the bidirectional effects of pediatric hypertension on neurocognitive and psychological outcomes are understudied. The objective of this review is to highlight the association between hypertension and cognition, attention, learning, and mental health in children and adolescents. In doing so, this review provides a framework and toolkit to integrate neuropsychology and psychology into the screening and management stages of pediatric hypertension. By recognizing the effects of hypertension on cognition, behavior, and mental health, screenings and interventions can be implemented to proactively and comprehensively improve the health outcomes for children with blood pressure concerns.

What Should I Wear to Clinic? A National Survey of Pediatric Orthopaedic Patients and Parents

BACKGROUND

A number of factors have been shown to affect how surgeons are subjectively viewed, including their appearance in clinic. Patient preference for pediatric orthopaedic surgeon attire has not previously been studied, nor has its influence on initial perception of the surgeon.

METHODS

At 5 pediatric regional sites across the United States, parents and patients presenting to the pediatric orthopaedic clinic were given anonymous surveys showing 8 photos of surgeons in different clinical dress including in business or scrub dress, each with or without white coat (WC). Subjects reported their demographics, single preferred photo, rated characteristics of the surgeons in each photo on a 5-point Likert scale, and answered specific questions on scrubs and WCs. The first consecutively completed 100 parent and 100 patient surveys were included from each site.

RESULTS

One thousand surveys were collected from patients (500) and parents (500). The majority felt a surgeon's clinical dress would not affect how they are cared for (83%), and that it was ok to wear scrubs in clinic (90%). Overall, WC was preferred to those without no matter the age, but there was no difference between scrub and business choices. Of those stating a preference, woman in business and WC (24%) and woman in scrubs and WC (21%) were most selected, with the only geographic difference being the midwest's preference for man in business and WC. Females were more likely to prefer women photographs (P<0.0001).

CONCLUSIONS

In general, pediatric orthopaedic patients and parents do not have a strong specific preference toward what their surgeon wears to clinic, including whether or not we are dressed in scrubs, but some initial biases exist. When asked to choose, the traditional WC worn over any attire is preferred, and female patients and parents uncover a preference for a surgeon of their own sex.

Vascular diameter and intima-media thickness to diameter ratio values of the carotid artery in 642 healthy children

In children, arterial alterations occur with increased intima-media thickness as well as vascular diameter enlargement. Both conditions correlate with higher cardiovascular risk in adults, and both the array and proportion of these alterations are important hemodynamic parameters. In terms of functional adaptation processes, they influence several arterial wall properties as for example the shear and tensile stress of the vessel. There are no reference values for the vascular diameter and intima-media thickness/diameter ratio of the carotid artery in children. Therefore, this study aimed to assess vascular diameter, intima-media thickness/diameter ratio and related tensile stress values in children and to further investigate the influence of sex, age, body mass index, and blood pressure. The parameters were measured with high-resolution semi-automated ultrasound. Sex- and age-dependent values were calculated with the LMS method for a cross-sectional sample of 642 healthy, non-obese children aged 8-17 years. The mean vascular diameter was 5.45 ± 0.46 mm; the median intima-media thickness/diameter ratio was 0.085 (0.079-0.092); the median tensile stress was 105.4 (95.2-116.4) kPa. The vascular diameter and the tensile stress were higher, and the intima-media thickness/diameter ratio was lower in boys than in girls. In comparison to the normal weight study population the excludedobese children had a significantly higher diameter, a lower intima-media thickness/diameter ratio, and a higher tensile stress. In multiple regression analyses of diameter, intima-media thickness/diameter ratio, and tensile stress, all parameters were influenced by sex and body mass index. Furthermore, systolic and diastolic blood pressure significantly influenced the vascular diameter, and systolic blood pressure significantly influenced the intima-media thickness/diameter ratio. Conclusion: This study is the first to report values for the diameter, the intima-media thickness/diameter ratio of the carotid artery, and the related tensile stress allowing a more differentiated view of cardiovascular adaptations as it combines structural and functional vascular parameters. What is known: • Intima-media thickness and vascular diameter are related to a higher cardiovascular risk in adults • The intima-media thickness/diameter ratio gives information about hemodynamic and functional vessel adaptation What is new: • Values for vascular diameter, intima-media thickness/diameter ratio, and tensile stress of the carotid artery in children are presented in this study • Intima-media thickness as a surrogate marker for arterial health in children should be complemented by intima-media thickness/diameter ratio measurement.

Elevated blood pressure and its relationship with bodyweight and anthropometric measurements among 8-11-year-old Indonesian school children

Objective: Increased prevalence of elevated blood pressure in children and adolescents was associated with increased body weight and measures. Also, prevalence of elevated blood pressure varies between countries. This study is to investigate the prevalence of elevated blood pressure in Indonesian children and its relationship with bodyweight and anthropometric measures. Methods: This cross-sectional study involved 1010 elementary students aged 8 - 12 years (479 girls, 531 boys). The anthropometric measures and blood pressure were assessed. Elevated blood pressure (EBP) was determined if at the 90^th percentile or above for gender, age, and height. Independent t-test, Chi-square, Pearson correlation, and multivariate logistic regression were applied. Significance was determined at p<0.05. Results: Overall prevalence of EBP was 28.8% (35.9% in girls, 22.4% in boys). BMI, waist circumference (WC), waist to height ratio (WHtR), and abdominal skinfold had significant correlation with EBP. Elevated BP was higher in overweight and obesity than in normoweight (60.5% vs 39.5%, p=0.00). In girls, the OR of EBP for overweight and obesity were 2.33 (95% CI 1.40-3.87, p=0.03) and 3.44 (95% CI 1.98-5.99, p=0.00) whereas in boys were 4.26 (95% CI 2.20-8.28, p=0.00) and 8.82 (95% CI 5.10-15.38, p=0.00). Conclusions: Prevalence of EBP in Indonesian school children aged 8 - 11 years was higher and more prevalent in overweight/ obesity and in girls. Anthropometric measures were correlated with EBP.

Pediatric Hypertension

Hypertension is an important and often overlooked problem in the pediatric population. In 2017, the American Academy of Pediatrics updated their guidelines for the diagnosis and management of hypertension. The new guidelines include a refined definition of the blood pressure stages and also a new diagnostic reference table with updated data excluding those with overweight or obesity. It also simplified the diagnostic criteria for adolescents and provided a screening table for easier use in the clinical setting. Along with the simplified diagnostic criteria, the new guidelines stress the importance of accurate blood pressure measurements and the growing importance of ambulatory blood pressure monitoring. With these revised guidelines, the diagnosis and management of blood pressure in the pediatric population should be clearer and easier to implement in clinical practice.

Novel Biomarkers of Early Atherosclerotic Changes for Personalised Prevention of Cardiovascular Disease in Cervical Cancer and Human Papillomavirus Infection

Cervical cancer is associated with a causative role of human papillomavirus (HPV), which is a highly prevalent infection. Recently, women with a genital HPV infection were found to have increased incidence of cardiovascular diseases (CVD), including severe cardiovascular events such as myocardial infarction and stroke. The pathomechanisms of this relation are not yet fully understood, and may significantly affect the health of a large part of the population. Accelerated atherosclerosis is assumed to play a key role in the pathophysiology of this relationship. To identify high-risk groups of the population, it is necessary to stratify the CVD risk. Current algorithms, as widely used for the estimation of CVD risk, seem to be limited by the individual misclassification of high-risk subjects. However, personalised prediction of cardiovascular events is missing. Regarding HPV-related CVD, identification of novel sensitive biomarkers reflecting early atherosclerotic changes could be of major importance for such personalised cardiovascular risk prediction. Therefore, this review focuses on the pathomechanisms leading to HPV-related cardiovascular diseases with respect to atherosclerosis, and the description of potential novel biomarkers to detect the earliest atherosclerotic changes important for the prevention of CVD in HPV infection and cervical cancer.

Physicians' Attire Influences Patients' Perceptions in the Urban Outpatient Orthopaedic Surgery Setting

BACKGROUND

Previous work has established that physician attire influences patients' perceptions of their physicians. However, research from different specialties has disagreed regarding what kinds of physician attire might result in increased trust and confidence on the part of patients.

QUESTIONS/PURPOSES

The purpose of this study was to investigate how surgeon attire affects patients' perceptions of trust and confidence in an urban orthopaedic outpatient setting.

METHODS

Eighty-five of 100 patients solicited completed a three-part questionnaire in the outpatient orthopaedic clinic at an urban teaching hospital. In the first section, participants viewed eight images, four of a male surgeon and four of a female surgeon wearing a white coat over formal attire, scrubs, business attire, and casual attire, and rated each image on a five-level Likert scale. Participants were asked how confident, trustworthy, safe, caring, and smart the surgeon appeared, how well the surgery would go, and how willing they would be to discuss personal information with the pictured surgeon. The participant ranked all images from most to least confident in the second part and the last section obtained demographic information from the patients. Surveys were scored using a five-level Likert scale and a Friedman test was used to detect statistical significance when comparing all attires. For multiple pairwise comparisons, a Bonferroni correction was applied.

RESULTS

The white coat on the male surgeon elicited modestly higher ratings in confidence (mean difference [MD], 0.367 ± 0.737; 95% CI, 0.202-0.532; p < 0.001), intelligence (MD, 0.216 ± 0.603; 95% CI, 0.077-0.356; p = 0.027), surgical skill (MD, 0.325 ± 0.658; 95% CI, 0.175-0.474; p < 0.001), trust (MD, 0.312 ± 0.613; 95% CI, 0.173-0.451; p < 0.001), ability to discuss confidential information (MD, 0.253 ± 0.742; 95% CI, 0.087-0.419; p = 0.023), caring (MD, 0.279 ± 0.655; 95% CI, 0.124-0.432; p = 0.006), and safety (MD, 0.260 ± 0.594; 95% CI, 0.125-0.395; p = 0.002) compared with business attire. Similarly, the white coat was preferred to casual attire in all categories (confidence: MD, 0.810 ± 0.921; smart: MD, 0.493 ± 0.801; surgical skill: MD, 0.640 ± 0.880; ability to discuss: MD, 0.564 ± 0.988; trust: MD, 0.545 ± 0.836; safety: MD, 0.581 ± 0.860; caring: MD, 0.479 ± 0.852; p < 0.001 for all comparisons). For the female surgeon, white coat and scrubs were not different, however the white coat was preferred to business attire in four of seven categories. Casual clothing was widely disliked in all categories for surgeons (men and women). When attire was compared for confidence on a scale, the white coat ranked higher than business (MD, 0.439 ± 1.491; p = 0.006) and casual attire (MD, 1.043 ± 2.054; p < 0.001), but not scrubs (MD, 0.169 ± 1.230; p = 1.000).

CONCLUSIONS

In this urban outpatient orthopaedic practice, patients' preferences varied based on the sex of the pictured surgeon in the survey. Overall, however, modest preferences were observed for the white coat in terms of confidence, intelligence, trust, and safety. Furthermore patients are more willing to discuss personal information and believe that their surgery will go better if the surgeon wears a white coat or scrubs. These results are consistent with those of several studies in other settings and therefore may be generalizable in other locations and specialties. Given the increasing awareness and concern for physician-spread hospital infection, this study lends support to scrub attire over business or casual attire if physicians do not wear a white coat.
