Background: Recent research has focused on the relationship between heart failure (HF) symptom clusters and outcomes, including mortality, hospitalization, functional status, and quality of life. No known studies to date have explored the role of physical HF symptom clusters and delays in seeking treatment.

Objectives: Describe physical symptom clusters in a population of HF patients and determine if a specific cluster is predictive of delay in seeking treatment for HF symptoms.

Method: We analyzed combined data from two studies ( n = 406) collected during acute HF hospitalization. The Heart Failure Somatic Awareness Scale quantified physical HF symptoms. Delay, measured in days, was collected from the medical record and confirmed by interview. Hierarchical agglomerative clustering techniques determined physical HF symptom clusters. Hierarchical multiple regression analysis was computed to explore predictors of delay.

Results: Participants were primarily White, male sex older adults. Three physical HF symptom clusters were identified: discordant, edema-related, and dyspnea-related symptoms. Hierarchical multiple regression analysis revealed in Step 1 that age was a significant predictor of delay.

Discussion: Our findings provide valuable insight into the role of physical symptom clusters on delay in persons with HF. Through agglomerative hierarchical clustering techniques, we found three physical HF symptom clusters that were then used to determine differences in cluster membership by demographic and clinical variables. Significant age differences were noted by cluster membership with youngest older adults in a discordant symptom cluster.

Background: Safe and reliable implementation of complex study protocols in multisite clinical trials requires that all study personnel have 24/7 access to up-to-date study materials. Study websites can serve as an electronic manual of operations (eMOO) to support trial conduct.

Objective: We describe the development, organization, and maintenance of a study website and eMOO to facilitate quick and efficient communication during conduct of a complex, multisite, international clinical trial.

Methods: We worked closely with our information technology department to develop and maintain our study website, which includes a public home page, a section for parents and families, and three password-protected portals that serve as an eMOO for (a) study sites, (b) study site investigators, and (c) the operations team (e.g., clinical coordination center, data coordination center).

Results: The public home page is helpful for families contemplating study participation and for nonparticipating sites considering joining our trial. The patient and family education section supports family participation in the study. The study site portal contains all information needed for local study teams to safely manage a study patient. The investigator portal provides access to research-specific materials needed to lead the study at each site. The operations team portal supports overall study management. For other scientists considering use of a study website for their multisite research, we recommend close collaboration with information technology for development and maintenance, limited and clearly defined roles for version control, and use of unmodifiable file formats to prevent unapproved alterations of study materials.

Discussion: Although investment in development and maintenance has been significant, we have appreciated marked value to our operations team and study sites. Our study website development process is relevant to other scientists conducting multisite clinical research.

Background: Chronic stress causes harmful physiological responses that yield increased inflammation and subsequent health conditions. Stress is an important measure among minoritized populations who face social situations that predispose risk to developing mental health problems. Hair and fingernail cortisol have been studied as retrospective measures of chronic stress and to demonstrate biological response to social situations.

Objectives: The objective of this study was to compare the Perceived Stress Scale (PSS) with hair and nail cortisol concentrations and assess the risk factors associated with stress levels among heterosexual and sexual and gender-minoritized adolescent males.

Methods: We recruited a cohort of adolescents who were assigned male sex at birth. Approximately half of our cohort consisted of sexual and gender-minoritized people, and half consisted of heterosexual cisgender males. Participants provided hair and nail samples and completed a survey that included demographic and hair hygiene questions and the PSS. Hair and nail samples were processed in a laboratory, and survey results were analyzed descriptively.

Results: Several samples were not provided or received, and some survey data were missing. Hair and nail cortisol values were significantly associated. There was no significant relationship between the PSS and hair and nail cortisol values. No significant differences were found between the heterosexual and sexual minoritized groups. Black participants reported lower perceived stress scores compared to White participants. Participants whose gender was nonbinary or genderqueer had higher hair cortisol values compared to those who identified as male. Older participants had higher hair cortisol values compared to younger participants.

Discussion: Previous researchers have similarly found no correlation between self-report stress scales and cortisol values, increased stress experience among nonbinary or genderqueer individuals compared to cisgender individuals, and a positive correlation between aging and stress. Yet, our finding that Black participants reported lower stress levels than White participants is unexpected. Our study demonstrates a high correlation between hair and nail cortisol values, suggesting the potential to substitute these markers as needed.

Background: Fear of childbirth affects women worldwide and can have adverse consequences. Midwives have implemented a number of interventions, autonomously or as part of a professional team. However, midwives have been unable to identify the most appropriate intervention for ensuring the reduction or alleviation of this fear to provide the best perinatal outcomes.

Objective: This study aimed to evaluate the effectiveness of a prenatal educational intervention followed by specific support during childbirth, designed and delivered exclusively by midwives for women with a high fear of childbirth.

Method: This randomized controlled trial was performed with two arms in two phases: an online prenatal education phase followed by a support phase during childbirth. Participating women with a high fear of childbirth, which was determined using the Wijma Delivery Expectancy Questionnaire A-Spanish version, were assigned to the experimental group or the usual care control group at a 1:1 ratio.

Results: Women showed a reduction in fear of childbirth in both phases of the study. According to the intention-to-treat analysis, a significant mean difference was observed in the prenatal stage in favor of the intervention group, and a nonsignificant difference was observed in favor of this same group after delivery.

Discussion: The effectiveness of continuous specific prenatal education with preferential support during childbirth by midwives was indicated by improvements in the level of fear of childbirth.

Background: Saudi Arabia has one of the highest childhood obesity rates worldwide. The primary factor associated with the high prevalence of obesity among adolescents is a lack of physical activity (PA). Compared to male adolescents, very few Saudi female adolescents meet the World Health Organization recommendation of achieving 60 minutes of moderate-to-vigorous PA per day, putting them at a higher risk of overweight and obesity.

Objective: This cross-sectional study aimed to examine the relationship between the theory of planned behavior and psychosocial factors, including attitude toward PA, subjective norms, perceived behavioral control (PBC), PA intention, and self-reported PA among Saudi female adolescents.

Methods: A convenience sample of 329 Saudi female adolescents was recruited from all-female public intermediate and high schools in the Eastern Region of Saudi Arabia. Data were collected using online self-administered questionnaires. The theoretical model was examined using structural equation modeling.

Results: The findings revealed a higher prevalence of overweight compared to obesity among participants. About half the participants were from families with a medium monthly income. The mean PA score indicated a low level of PA. The model demonstrated significant explanatory power for both PA intention and PA behavior, respectively. The strongest predictor of adolescents' intention was attitude, followed by PBC.Moreover, the female adolescents' attitudes and PBC had significant indirect effects on self-reported PA through intention, whereas intention had a direct effect on PA. The model did not support a direct or indirect relationship between subjective norms and PA.

Discussion: The findings provide essential support for targeting attitude and perceived behavior control of female adolescents in order to enhance their PA intention. This theoretical understanding can help design effective theory-based interventions that promote PA among Saudi female adolescents.
