Expanding eligibility and improving quality of cervical cancer screening in Estonia: The 2021 reforms.

Estonia has one of the highest death rates from cervical cancer in the European Union despite having had a population-based screening programme for over 15 years. In 2021, this high disease burden, alongside a new national cancer prevention plan, prompted a series of cervical cancer screening programme reforms to address low screening uptake and evidence of variable screening test quality. The reforms had three main elements: expansion of eligibility to all women aged 30-65 regardless of insurance status; increasing test provision by enabling family physicians to take screening samples and introducing self-sampling; and improving testing procedures, replacing cytology with HPV testing as the primary screening test. Although the impact of these changes is yet to be seen, early signs suggest increased programme participation. However, at 51 %, further action to address barriers to uptake will likely be necessary. If Estonia is to avoid another period of policy dormancy, as happened between 2006 and 2021, greater clarity on screening programme accountability is required. The establishment of the National Cancer Screening Group may enable this. The first test will be the delivery of an end-to-end evaluation of the reformed programme, with an emphasis on equity of access. The next step will be to develop and deliver solutions that respond to these needs.

Meeting the challenges of the 21st century: the fundamental importance of trust for transformation.

BACKGROUND: This paper is one of a collection on challenges facing health systems in the future. One obvious challenge is how to transform to meet changing health needs and take advantage of emerging treatment opportunities. However, we argue that effective transformations are only possible if there is trust in the health system. MAIN BODY: We focus on three of the many relationships that require trust in health systems, trust by patients and the public, by health workers, and by politicians. Unfortunately, we are seeing a concerning loss of trust in these relationships and, for too long, the importance of trust to health policymaking and health system functioning has been overlooked and under-valued. We contend that trust must be given the attention, time, and resources it warrants as an indispensable element of any health system and, in this paper, we review why trust is so important in health systems, how trust has been thought about by scholars from different disciplines, what we know about its place in health systems, and how we can give it greater prominence in research and policy. CONCLUSION: Trust is essential if health systems are to meet the challenges of the 21st century but it is too often overlooked or, in some cases, undermined.

Community-based rehabilitation for people with psychosocial disabilities in low- and middle-income countries: a systematic review of the grey literature.

BACKGROUND: Community based rehabilitation (CBR) aims to promote the inclusion and participation of people with disabilities, particularly in low- and middle-income countries (LMICs). Yet people with psychosocial disabilities are often excluded from CBR programmes. The restrictive inclusion criteria used by previous reviews make it difficult to identify promising examples that could otherwise help to inform the uptake of CBR for people with psychosocial disabilities. We aim to address this gap using gold standard methods for the review and synthesis of grey literature on CBR for people with psychosocial disabilities in LMICs. METHODS: Our search strategy was developed in consultation with an expert advisory group and covered seven grey literature databases, two customised Google Advanced searches, 34 targeted websites and four key reports. A single reviewer screened the search results and extracted relevant data using a standardised format based on the World Health Organisation's CBR matrix. The included programmes were then checked by a second reviewer with experience in CBR to ensure they met the review's criteria. A narrative synthesis with summative content analysis was performed to synthesise the findings. RESULTS: The 23 CBR programmes identified for inclusion spanned 19 countries and were mostly located in either rural areas or urban areas where a large proportion of the population was living in poverty. 13 were classified as livelihood programmes, eight as empowerment programmes, seven as social programmes, seven as health programmes and four as education programmes. Only two addressed all five of these components. 12 of the included programmes reported challenges to implementation, with stigma and lack of resources emerging as two of the most prominent themes. CONCLUSION: This grey literature review identified several CBR programmes and synthesised key learning that would have otherwise been missed by a more traditional review of the published literature. However, as evaluation by implementing organisations is not always conducted to a high standard, the quality of this evidence is generally poor. A flexible monitoring and evaluation framework for CBR programmes could help to reduce heterogeneity in terms of the quality and content of reporting.

Perceived Stigma in Patients with Autoimmune Hepatitis.

Perceived stigma (PS) adversely impacts psychosocial and disease outcomes in patients with chronic liver diseases (CLD), and those with autoimmune hepatitis (AIH) may be at risk for PS given inaccurate assumptions about the origin of their diagnosis. The aims of the current study are to describe the frequency of PS in patients with AIH, compare rates of PS in AIH to rates of PS in primary biliary cholangitis (PBC) and CLD, and examine demographic correlates of PS. 262 adults with AIH (95% female, Mage = 51.53 years) completed online questionnaires on demographics, disease information, and PS. 54-68% reported PS with themes of selective disclosure, non-disclosure, or hiding diagnosis. PS was higher in those with AIH compared to those with PBC, but lower than those with various CLD. Age was inversely related to PS. Given the results, provider screening of PS and integration of clinical health psychologists may be helpful for identifying PS in patients with AIH.

Factors influencing the participation of groups identified as underserved in cervical cancer screening in Europe: a scoping review of the literature.

Background: Cervical cancer is a preventable and inequitably distributed disease. Screening plays a vital role in prevention, but many women face barriers to participation. The aims of this scoping review, undertaken to inform the co-design of interventions to equitably increase screening uptake, were to: (1) identify barriers and facilitators to cervical cancer screening for underserved populations, and (2) identify and describe the effectiveness of interventions aimed at improving participation in cervical cancer screening among underserved groups in Europe. Methods: Qualitative, quantitative, and mixed methods studies focusing on barriers and facilitators to cervical screening participation and interventions to improve uptake undertaken in Europe and published after 2000 were included. Four electronic databases were searched to identify relevant papers. Titles and abstracts were screened, full text reviewed, and key findings extracted. Data were extracted and analyzed according to different health system strata: system-wide (macro), service specific (meso) and individual/community specific (micro). Within these categories, themes were identified, and the population groups impacted were recorded. All findings are presented in accordance with (PRISMA) guidelines. Results: 33 studies on barriers and facilitators and eight intervention studies met the inclusion criteria. Collectively, the findings of these studies presented a wide array of screening uptake barriers, facilitators, and interventions, predominantly related to screening service and individual/community factors. However, although diverse, certain core themes around information provision, prompts for participation and the need for inclusive spaces were apparent. Implementation of screening programs should focus on: (1) reducing identifiable barriers, (2) increasing public awareness, and (3) providing patient reminders and measures to promote engagement by healthcare providers. Conclusion: There are many barriers to uptake of cervical cancer screening and this review, nested within a larger study, will inform work to devise a solution alongside groups identified in three European countries.

Vaccine Attitudes Mediate Relationships Between Caregiver Political Ideology and Likelihood of Child Vaccination for COVID-19.

INTRODUCTION: The COVID-19 vaccine has become available to children ages 5-12, yet vaccine uptake is suboptimal. Political ideology is a correlate of COVID-related beliefs and vaccine likelihood among US adults. However, since political ideology is not easily modifiable, attention to modifiable mechanisms that may explain links between political ideology and vaccine hesitancy is important in addressing this public health crisis. Caregiver attitudes around vaccine safety and efficacy have been related to vaccine uptake in other populations and warrant additional study in the context of COVID-19. The current study examined whether caregiver's attitudes regarding the safety and efficacy of the COVID-19 vaccine mediated the relationship between caregiver political ideology and likelihood of having their child vaccinated. METHODS: 144 US caregivers of children (6-12 years) completed an online survey in summer 2021 to assess political ideology, vaccine-related beliefs, and likelihood of having their child vaccinated against COVID-19. RESULTS: Caregivers with more liberal political views reported higher likelihood of eventual child vaccination compared to caregivers who reported a more conservative views (t(81) = 6.08, BCa CI [2.97, 5.67]). Moreover, parallel mediation models indicated caregiver?s perceptions of risks (BCa CI [-.98, -.10]) and efficacy (BCa CI [-3.16, -2.15]) of the vaccine each mediated the aforementioned relationship, with perceived efficacy explaining significantly more variance than risks. CONCLUSIONS: Findings extend knowledge by identifying social cognitive factors that impact caregiver vaccine hesitancy. Interventions to address caregiver's hesitancy to have their child vaccinated through modifying caregiver's inaccurate beliefs regarding vaccines or enhancing perceptions of vaccine efficacy is warranted.

Salivary cortisol levels and appraisals of daily hassles across dimensions of the tripartite model of anxiety and depression in emerging adults.

The objective of this study was to investigate how cortisol levels and appraisals of daily hassles differ across tripartite dimensions of depression and anxiety in emerging adults. Data collected from a sample of undergraduate students at a large Midwestern university was used to investigate these aims. This included salivary cortisol data collected over four days, scores on a measure of the tripartite model of anxiety and depression, and scores on a measure of daily hassles administered everyday for two weeks. Generalized estimating equations and multilevel modeling techniques were used to analyze data. Elevated cortisol levels during the awakening period and the evening period, lower total levels across the day, steeper diurnal slopes, and elevated levels of negative affect and physiological hyperarousal predicted experiences of daily hassles. Tripartite dimensions were unrelated to cortisol indices. The present study demonstrates the utility of modeling multiple cortisol indices and provides evidence of differential associations between physiological and phenomenological indices of stress.

Relationships Between Abdominal Pain, Mental Health, and Functional Disability in Youth With Inflammatory Bowel Diseases: Pain Catastrophizing as a Longitudinal Mediator.

OBJECTIVES: Abdominal pain can be a debilitating symptom for youth with inflammatory bowel diseases (IBDs). Across various pediatric conditions, pain predicts adverse physical and mental health outcomes. Understanding mechanisms by which pain impacts outcomes is of critical importance to enhance the well-being of those with IBDs. Pain catastrophizing mediates the aforementioned relationships in other pediatric populations, but little research has examined its role in pediatric IBDs. Attention to the role of pain catastrophizing as a potential mediator in pediatric IBD is the important given unique elements of the pain experience for this population. This study aimed to examine pain catastrophizing as a potential mediator of the relationship between abdominal pain and adverse outcomes in youth with IBDs. METHODS: Seventy six youth (ages 11 to 18; M [SD] age=14.71 [1.80]) with IBD completed the Abdominal Pain Index (T1), Pain Catastrophizing Scale (T2, week 12), Revised Children's Anxiety and Depression Scale (T3, week 20), and Functional Disability Inventory (T3, week 20). RESULTS: Catastrophizing mediated the relationship between abdominal pain and both anxiety symptoms ( b =1.61, Bias-Corrected Accelerated [BCa] CI, 0.25, 4.62) and functional disability ( b =0.77, BCa CI, 0.15, 2.38). A direct effect of abdominal pain on low mood was also noted ( b =1.17, BCa CI, 0.03, 2.50). Post hoc analyses examining mediation via catastrophizing subscales indicated that while magnification and rumination functioned as mediators, helplessness did not. DISCUSSION: Findings are consistent with fear avoidance models and suggest that interventions directed at pain catastrophizing may be worthwhile in pediatric IBD populations, given catastrophizing-mediated relationships between pain and mental and physical health outcomes.

Do Patient Personality Traits and Self-Reported Physical and Psychosocial Symptoms Help to Predict Hallux Valgus Surgery Outcomes?

As many as 10% of patients remain unsatisfied after hallux valgus surgery. We explored the effects of patient personality traits and other preoperative patient characteristics on patient-reported outcomes following surgery. Eighty consecutive adult patients (mean age 45 ± 14 years, 91% female [73/80]) undergoing scarf bunionectomy at our practice were prospectively enrolled from January 2016 to January 2017 and followed for 12 months. Predictor variables included preoperative physical and psychosocial complaints (determined via Brief Battery for Health Improvement-2 questionnaire), patient aggression level, and personality traits (extraversion, agreeableness, conscientiousness, emotional stability and openness). Primary outcome measures included the Foot and Ankle Outcome Score (FAOS) with its 5 subscales, and patient satisfaction. Multiple multivariable regression models were used to determine preoperative patient characteristics associated with FAOS outcome and satisfaction at 12 months. Seventy subjects (70/80, 87.5%) completed the study. All patients experienced technically successful surgery. In the multivariable regression analyses, none of the combinations of potentially important predictor variables explained more than 19.8% of the variance in any of the 5 FAOS subscales at 12 months (range: 6.1%-19.8%). Furthermore, no predictor was associated with patient satisfaction in either the univariate or multivariable analyses. We conclude that patient personality traits, aggression level, and self-reported physical and psychological symptoms do very little to predict outcomes in hallux valgus surgery. As healthcare delivery in the United States has increasingly prioritized patient satisfaction, we will need to broaden the quest for predictors associated with our best (and worst) patient-reported outcomes after hallux valgus surgery.

Perceived effect of pediatric inflammatory bowel diseases on academics, college planning, and college adjustment.

ObjectiveTo examine the relationship between perceived effect of inflammatory bowel diseases (IBD) on high school academics and college planning on college adjustment. Participants: Participants (N = 97) were college students with IBD. Methods: Participants completed an online survey including the Student Adaptation to College Questionnaire and study-developed questions assessing the perceived impact of their diagnosis on their high school academics and college planning. Results: Most participants reported average college adjustment across domains, except personal-emotional adjustment with 47% of participants falling within the very low to low ranges. Nearly half reported IBD impacted their choice of college (49%). The impact of IBD on college planning was most consistently associated with domains of college adjustment. Conclusions: IBD severely impacts college planning, decision-making, and adjustment in college-bound youth. Perceiving that having a chronic illness impacts college planning may result in greater difficulty with academic adjustment, attachment to the institution, and social adjustment during college.

Caregiver perceptions of importance of COVID-19 preventative health guidelines and difficulty following guidelines are associated with child adherence rates.

OBJECTIVE: To describe child adherence to four preventative-health guidelines during the COVID-19 pandemic and investigate caregiver-level correlates of adherence. METHOD: Two hundred thirty-six caregivers (75% female) of children ages 6-12 years (Mage = 8 years; 53% male) living in the United States rated child adherence to four preventative-health guidelines between 10/16/2020 and 11/14/2020. Caregivers also rated perceived importance of each guideline in limiting virus spread and perceived difficulty in obtaining child compliance. RESULTS: Child adherence was highest for mask-wearing (median [Mdn] = 96%) and hand hygiene (Mdn = 95%). Adherence to social distancing guidelines was lower. Mdn adherence for social distancing with family outside the household was 80%, and Mdn adherence for social distancing with friends was 72%. Furthermore, for each of the four guidelines, fewer than half the sample reported 100% adherence (range = 20%-43%). Adherence was positively associated with caregiver perceptions of importance of a given behavior in limiting virus spread (rs = .38-.62) and negatively associated with perceived difficulty in gaining child compliance (rs = -.37-.25). DISCUSSION: Current results indicated parents perceive child adherence to social distancing more challenging than child adherence to mask wearing or hand hygiene. Lower caregiver perceptions of importance of the behavior and greater perceived difficulty in gaining child compliance were associated with lower adherence to all tasks. Brief targeted interventions (e.g., motivational interviewing, parent behavior management training) may be well suited to enhance caregivers' perceptions of value of the behavior, while also addressing behavioral challenges that interfere with child adherence.

Using Technology to Assess Bidirectionality between Daily Pain and Physical Activity: The Role of Marginalization during Emerging Adulthood.

Emerging adulthood is often overlooked as a developmental time period critical to shaping future health outcomes. Recurrent pain is a commonly experienced health concern within this age group, particularly headaches and low back pain, and early experiences of recurrent pain are related to subsequent chronic pain and disability. Furthermore, adults from marginalized populations report more frequent and severe recurrent pain. Many studies have demonstrated the therapeutic effect of physical activity on pain relief; however, others have demonstrated that physical activity can also exacerbate pain symptoms. Therefore, the current study aimed to (1) assess a bidirectional relationship between reported pain and engagement in physical activity among an emerging adult sample (N = 265) and (2) determine whether sociodemographic factors moderate this relationship. Using longitudinal daily reported pain and ActiGraph monitor data collected over two weeks, a novel dynamic structural equation modeling approach was employed. Results indicated no significant cross-lagged relationships between pain and physical activity, and no significant moderation effects. These findings suggest that a bidirectional relationship does not exist among a diverse college sample of emerging adults even after considering sociodemographic moderators. Excellent retention and few missing data suggest that using accelerometers and daily diaries are feasible methods to collect data in this population. Sample considerations and future analytical approaches are discussed.

Emerging Adults' Adherence to Preventative Health Guidelines in Response to COVID-19.

OBJECTIVE: To examine rates of emerging adults' (EA) adherence to preventative health behavior recommendations during early months of the COVID-19 pandemic and to investigate demographic (i.e., gender, years of education, socioeconomic status, school enrollment status, and living situation) and exposure and impact-related correlates of adherence. METHODS: Participants were 273 [M (SD) age = 22 (2.1) years, 55% female, 32% from minoritized groups] EA completed an online survey of adherence to 11 preventative health behaviors recommended by the Centers for Disease Control (CDC) during summer 2020. Participants rated adherence via a visual analog scale. Participants also reported demographic information and completed the COVID-19 Exposure and Family Impact Adolescent and Young Adult Version (CEFIS-AYA). RESULTS: Median levels of adherence to preventative recommendations ranged from 66% to 100%. Highest adherence levels (Mdn > 90%) were reported for quarantining if exposed to COVID-19; covering mouth when sneezing; avoiding the elderly/those at high risk; and avoiding large gatherings. Median adherence was <80% for mask wearing; maintaining a 6-foot distance; avoiding in-person visits with romantic partners or friends; and disinfecting surfaces. Female gender was the only variable significantly associated with overall adherence, and it explained 4% of the variance. CONCLUSIONS: Following guidelines related to social distancing practices may be particularly challenging for EA, possibly because of unique developmental needs of this group, and males may be at greater risk for non-adherence to CDC recommendations. Therefore, public health messaging and adherence intervention development should be designed with males and social distancing practices in mind.

Communication About Medication by Providers-Adolescent and Young Adult Version: Confirmatory Factor Analyses.

OBJECTIVE: To replicate the factor structure of a patient-report measure of provider communication about key medication prescription information, the Communication about Medication by Providers-Adolescent and Young Adult (CAMP-AYA) Version. We evaluated whether the 15-item, two-factor structure identified previously could be replicated via confirmatory factor analysis, and we also examined fit of unidimensional and bifactor models. Associations of CAMP-AYA Total and Factor Scores with provider satisfaction and select patient and medication characteristics were also examined. METHODS: Participants were 739 AYA (ages 18-25) who completed the CAMP-AYA, a provider satisfaction rating, and provided demographic and medication information. RESULTS: The bifactor model was best fitting (χ2 [75] = 689.60, p < .0001; root mean squared error of approximation = 0.11, 90% CI [0.10, 0.11]; Comparative Fit Index = 0.98; Tucker-Lewis Index = 0.98; Standardized Root Mean Square Residual Index = 0.02). Internal consistency reliabilities for Total and Factor Scores were high (αs > .89) and Total and Factor Scores were associated with provider satisfaction (ps < .001). CAMP-AYA scores varied as a function of type of prescription (short vs. long term; new vs. refill), with higher scores reported in the context of long term (>30-day course) or refilled prescriptions (ps < .007) in most cases. CONCLUSIONS: This study provides additional support for the reliability of the CAMP-AYA as a tool to assess AYA perceptions of provider key information coverage about medication prescriptions.

Family Support is Associated with Fewer Adherence Barriers and Greater Intent to Adhere to Oral Medications in Pediatric IBD.

PURPOSE: Medication nonadherence is common among adolescents, and family support can enhance adherence. In a sample of youth with inflammatory bowel disease (IBD), we aimed to describe barriers to oral medication adherence and intent to adhere. Additionally, we examined the role of family support in influencing adherence barriers and intent to adhere, and assessed if age moderated these relationships. DESIGNS AND METHODS: A secondary analysis of baseline data from an adherence-promotion intervention trial was conducted. Youth reported perceptions of family support, adherence barriers, and intent to adhere via validated measures. RESULTS: Among youth (N = 76, ages 11-18), age moderated the impact of family support on total adherence barriers, disease/regimen barriers, social support/self-efficacy barriers, and intent to adhere. At higher levels of family support, younger (Mage = 12.93 years) and mid-age (Mage = 14.68 years) youth reported fewer barriers to adherence and greater intent to adhere. No main effect of family support or evidence of age moderation was found for denial/distrust or peer influences barrier domains. CONCLUSIONS: Younger and mid-aged adolescents benefitted from family support in the context of IBD management. Future research should examine whether interventions to enhance family support may enhance youth adherence. PRACTICAL IMPLICATIONS: Given prior findings highlighting the success of nurse-led interventions in promoting adherence in patients with IBD, present findings suggest additional intervention points for nurses working with pediatric IBD populations.

Hassles predict physical health complaints in undergraduate students: a dynamic structural equation model analysis of daily diary data.

OBJECTIVE: Daily hassles and physical health complaints are common among undergraduate students, and both are related to negative academic and psychosocial outcomes. However, the extent to which hassles or health complaints persist from day to day is underexplored, and studies examining whether hassles predict health complaints or vice versa, are lacking. This study aimed to examine the temporal stability and to define the temporal relationship between daily hassles and health symptoms in undergraduate students. DESIGN: Participants (n = 255, mean age = 19.2 years, 69% female, 53% White) completed 14 consecutive daily diaries of hassles and health complaints. MAIN OUTCOME MEASURES: Daily reports of the Brief College Students Hassles Scale and the Patient Health Questionnaire-15. RESULTS: Hassles and health complaints demonstrated stability through autocorrelations. Hassles significantly predicted subsequent health complaints, but health complaints did not significantly predict subsequent hassles. However, the two paths did not differ significantly. CONCLUSION: Students reporting elevations in one or both domains may benefit from interventions aimed at reducing daily hassles, in order to promote better perceived health and well-being.

Pain Symptomatology and Management in Pediatric Ehlers-Danlos Syndrome: A Review.

Ehlers-Danlos syndromes (EDS) are a group of connective tissue disorders that manifest with hyperextensibility of joints and skin, and general tissue fragility. While not a major criterion for clinical diagnosis, pain is a frequently endorsed symptom across subtypes of EDS. As such, the present review aims to summarize research to date on pain characteristics and management, and the relationship between such pain symptomatology and quality of life in pediatric EDS. Characteristics of pain, including theorized etiology, relative intensity and extent of pain are described, as well as descriptions of frequently endorsed pain sites (musculoskeletal, and non-musculoskeletal). Interventions related to the management of musculoskeletal (e.g., pharmaceutical intervention, physical therapy) and non-musculoskeletal pain (e.g., pharmaceutical and psychological interventions) are discussed, highlighting the need for additional research related to pediatric pain management in the context of hypermobility syndromes. In addition, the relationship between pain in pediatric EDS and quality of life is described. Finally, limitations of literature to date are described and recommendations for future lines of research are outlined.

Influence of Provider Communication on Emerging Adults' Medication Cognitions and Provider Satisfaction.

OBJECTIVE: This study examined how the content of medical provider communication related to medication prescriptions influenced emerging adults' (EA) medication-related cognitions and satisfaction with care. METHODS: In total, 257 EA (ages 18-25) were randomized to one of three audio vignettes depicting a medical appointment in which the EA imagined him/herself as the recipient of an oral antibiotic prescription. Provider communication content varied by vignette as follows: the positive outcome expectancy (POE) vignette focused on enhancing patient POE related to antibiotic use; the negative outcome expectancy (NOE) vignette focused on reducing patient NOE; and the standard care vignette focused on providing factual medication information. Following the vignette, participants self-reported on demographics, select medication-related cognitions, and provider satisfaction from vignette. RESULTS: Those in the NOE vignette condition reported higher provider satisfaction, perceived the provider to have given more information, and evidenced lower NOE and higher POE about the antibiotic compared with those in the other conditions. Intent to adhere did not vary by vignette condition. CONCLUSIONS: Brief, provider-initiated communication focused on reducing patient NOE may have unique value in altering EA's medication-related cognitions. Given that medication-related beliefs are known correlates of adherence, future research should replicate and expand these findings in the context of real-world medical encounters and through the utilization of objective indices of medication adherence to more fully understand the potential significance of provider language emphasizing reduction of NOE on medication adherence.

Development and Initial Validation of the Communication About Medication by Providers-Parent Scale (CAMP-P).

This study evaluated the psychometric properties of the Communication about Medication by Providers-Parent Scale (CAMP-P), a 24-item measure of communication relevant to medication adherence between parents and medical providers. Parents of youth (ages 2-7 years) who had received a prescription within the last 12 months completed online surveys regarding demographic and appointment variables, and child's recent prescription medications, and they completed the newly developed CAMP-P. Exploratory factor analysis of CAMP-P identified 20 items about provider communication corresponding to 3 distinct scales: medication administration strategies, encouraging communication, and addressing barriers to medication taking. Factor scales were related to appointment variables, such as length of time spent discussing medications. The CAMP-P demonstrated good internal consistency and convergent and divergent validity. The CAMP-P is a novel, validated measure of parent perceptions of medication communication and can be utilized to evaluate parent-provider communication on pediatric medication adherence in clinical and research settings.
