Data driven model of midportion achilles tendinopathy health created with factor analysis.

BACKGROUND: Achilles tendinopathy is a complex injury and the clinical presentation spans multiple different domains: physical and psychological symptoms, lower extremity function and tendon structure. A conceptual model of Achilles tendon health comprising these domains has been proposed in the literature. The aim of the study was to fit a model of Achilles tendinopathy using factor analysis and compare that to the conceptual model. An inclusive approach using a wide range of variables spanning multiple potential domains were included. METHODS: Participants (N = 99) with midportion Achilles tendinopathy were assessed with variables representing symptoms, physical function, tendon structure, metabolic syndrome, and psychologic symptoms. A Kaiser-Mayer-Olkin index was used to determine suitable variables for a subsequent exploratory factor analysis. RESULTS: A model emerged with an acceptable fit to the data (standardized root mean square of residuals = 0.078). Five uncorrelated factors emerged from the model and were labelled as biopsychosocial, lower extremity function, body size, load tolerance, and tendon structure. The total explained variance was 0.51 with the five factors explaining 0.14, 0.12, 0.10, 0.08, and 0.07 respectively. The results differed from the conceptual model as the factors of psychological variables and metabolic variables did not emerge from the analysis. CONCLUSION: A data driven model of Achilles tendon health supports assessment of the clinical presentation over multiple domains. As the factors are uncorrelated, the results of assessment of, for example, tendon structure should not be expected to be associated with lower extremity function or biopsychosocial limitations. The results suggest that the Patient Reported Outcomes Measurement Information System, counter-movement jump height, body mass index, pain with hopping, and the tendon cross-sectional area can evaluate the five factors, respectively.

Prioritisation for future surveillance, prevention and control of 98 communicable diseases in Belgium: a 2018 multi-criteria decision analysis study.

BACKGROUND: National public health agencies are required to prioritise infectious diseases for prevention and control. We applied the prioritisation method recommended by the European Centre for Disease Prevention and Control to rank infectious diseases, according to their relative importance for surveillance and public health, to inform future public health action in Belgium. METHODS: We applied the multi-criteria-decision-analysis approach. A working group of epidemiologists and statisticians from Belgium (n = 6) designed a balanced set of prioritisation criteria. A panel of Belgian experts (n = 80) allocated in an online survey each criteria a weight, according to perceived relative importance. Next, experts (n = 37) scored each disease against each criteria in an online survey, guided by disease-specific factsheets referring the period 2010-2016 in Belgium. The weighted sum of the criteria's scores composed the final weighted score per disease, on which the ranking was based. Sensitivity analyses quantified the impact of eight alternative analysis scenarios on the top-20 ranked diseases. We identified criteria and diseases associated with data-gaps as those with the highest number of blank answers in the scoring survey. Principle components of the final weighted score were identified. RESULTS: Working groups selected 98 diseases and 18 criteria, structured in five criteria groups. The diseases ranked highest were (in order) pertussis, human immunodeficiency virus infection, hepatitis C and hepatitis B. Among the five criteria groups, overall the highest weights were assigned to 'impact on the patient', followed by 'impact on public health', while different perceptions were identified between clinicians, microbiologists and epidemiologists. Among the 18 individual criteria, 'spreading potential' and 'events requiring public health action' were assigned the highest weights. Principle components clustered with thematic disease groups. Notable data gaps were found among hospital-related diseases. CONCLUSIONS: We ranked infectious diseases using a standardised reproducible approach. The diseases ranked highest are included in current public health programs, but additional reflection for example about needs among risk groups is recommended. Cross-reference of the obtained ranking with current programs is needed to verify whether resources and activities map priority areas. We recommend to implement this method in a recurrent evaluation cycle of national public health priorities.

Evaluation of quality of life among dental students using WHOQOL-BREF questionnaire in Saudi Arabia: A cross sectional study.

OBJECTIVE: The objective was to use modified version of WHOQOL-BREF to assess the well-being and QOL of dental students of King Saud University based on four major domains. METHODS: The questionnaire related to the survey was distributed to all dental students (N= 782) who were enrolled from 1st year to 5th year in College of Dentistry, King Saud University in the fall of 2018. The questionnaire comprised of four domains having different set of questions i.e. Physical domain, Psychological domain, Environmental domain and Social relationship domain. Two stand-alone questions related to (Overall Quality of life and Satisfaction with health) were also part of the WHOQOL-BREF questionnaire. Cronbach's Alpha was used to assess the reliability of the WHOQOL-BREF domains. Paired t-tests were conducted to compare the means of the four domains and chi-square. Chi-square test was used to find association of demographic characteristics with four domains and two stand-alone questions. RESULTS: The overall quality of life and satisfaction with health of the dental students was found to be satisfactorily favorable with environmental domain and moderately favorable with social relationship and physical health domains. Physical health domain with psychological domain was statistically significant (p-value <0.001) whereas physical health domain with social relationship and environmental domain was also found to be statistically significant (p-value <0.001). Respondents, who highly rated their overall quality of life and satisfaction with health, had higher domain scores. CONCLUSION: In the present study, overall quality of life and satisfaction with health of dental students in King Saud University was found to be satisfactorily favorable.

Resiliency in burn recovery: a qualitative analysis.

This phenomenological study engaged an availability sample of eight, long-term, adult burn survivors living a primarily rural burn center catchment area of the U.S. in face-to-face interviews focused on their holistic health since their burn injuries occurred. Criteria for the primary study involved females (n = 1) and males (n = 7) with an age range of 18 to 65 years and a minimum of 20% total body surface area (TBSA) injuries that required hospitalization in a specialized burn center. The mean age of participants at the time of interviews was 54.38 years. Burns ranged between 20% and 98% TBSA and one to 22 years since burn injuries occurred. Thematic data analysis revealed resilient protective factors as contributing to participants' post-burn health and recoveries. Resilient factors included resourcefulness, achievement motivation, optimism, spirituality, and empathy. Increased understanding of resilient protective factors and how they impacted long-term burn recovery in this sample may aid social workers in development and implementation community-based interventions in rural communities that promote resilience, health/mental health and long-term recovery for this population and others who have experienced trauma.

Comparing health-related quality of life of Dutch and Chinese patients with traumatic brain injury: do cultural differences play a role?

BACKGROUND: There is growing interest in health related quality of life (HRQoL) as an outcome measure in international trials. However, there might be differences in the conceptualization of HRQoL across different socio-cultural groups. The objectives of current study were: (I) to compare HRQoL, measured with the short form (SF)-36 of Dutch and Chinese traumatic brain injury (TBI) patients 1 year after injury and; (II) to assess whether differences in SF-36 profiles could be explained by cultural differences in HRQoL conceptualization. TBI patients are of particular interest because this is an important cause of diverse impairments and disabilities in functional, physical, emotional, cognitive, and social domains that may drastically reduce HRQoL. METHODS: A prospective cohort study on adult TBI patients in the Netherlands (RUBICS) and a retrospective cohort study in China were used to compare HRQoL 1 year post-injury. Differences on subscales were assessed with the Mann-Whitney U-test. The internal consistency, interscale correlations, item-internal consistency and item-discriminate validity of Dutch and Chinese SF-36 profiles were examined. Confirmatory factor analysis was performed to assess whether Dutch and Chinese data fitted the SF-36 two factor-model (physical and mental construct). RESULTS: Four hundred forty seven Dutch and 173 Chinese TBI patients were included. Dutch patients obtained significantly higher scores on role limitations due to emotional problems (p < .001) and general health (p < .001), while Chinese patients obtained significantly higher scores on physical functioning (p < .001) and bodily pain (p = .001). Scores on these subscales were not explained by cultural differences in conceptualization, since item- and scale statistics were all sufficient. However, differences among Dutch and Chinese patients were found in the conceptualization of the domains vitality, mental health and social functioning. CONCLUSIONS: One year after TBI, Dutch and Chinese patients reported a different pattern of HRQoL. Further, there might be cultural differences in the conceptualization of some of the SF-36 subscales, which has implications for outcome evaluation in multi-national trials.

Selection of key health domains from PROMIS® for a generic preference-based scoring system.

PURPOSE: We sought to select a parsimonious subset of domains from the patient-reported outcomes measurement information system (PROMIS®) that could be used for preference-based valuation. Domain selection criteria included face validity, comprehensiveness, and structural independence. METHODS: First, 9 health outcomes measurement experts selected domains appropriate for a general health measure using a modified Delphi procedure. Second, 50 adult community members assessed structural independence of domain pairs. For each pair, the participant was asked if it were possible to have simultaneously good functioning in domain 1 but poor functioning in domain 2, and vice versa. The community members also rated the relative importance of the domains. Finally, the experts selected domains, guided by community members' judgments of structural independence and importance. RESULTS: After 3 rounds of surveys, the experts agreed on 10 potential domains. The percent of pairs deemed structurally independent by community members ranged from 50 to 95 (mean = 78). Physical Function, Pain Interference, and Depression were retained because of their inclusion in existing preference-based measures and their importance to community members. Four other domains were added because they were important to community members and judged to be independent by at least 67% of respondents: Cognitive Function-Abilities; Fatigue; Ability to Participate in Social Roles and Activities; and Sleep Disturbance. CONCLUSION: With input from measurement experts and community members, we selected 7 PROMIS domains that can be used to create a preference-based score.

Integrative health care - What are the relevant health outcomes from a practice perspective? A survey.

BACKGROUND: Integrative health care (IHC) is an innovative approach to health care delivery. There is increasing focus on and demand for the evaluation of IHC practices. To ensure such evaluations capture their full scope, a clear understanding of the types of outcomes relevant to an IHC approach is needed. The objective was to describe the health domains and health outcomes relevant to IHC practices in Canada. METHODS: An online survey of Canadian IHC clinics. Survey questions were informed by the IN-CAM Health Outcomes Database. Descriptive statistics were used to summarize the data. Chi square tests were used to compare responses between clinic types and patient groups served. RESULTS: Surveys were completed by 21 clinics (response rate: 50%). Physical, psychological, social, individualized and holistic were identified as applicable health domains by more than 90% of the clinics. Spiritual domain was the least relevant (70% of clinics). A number of relevant outcomes within each domain were identified. A core set of outcomes were identified and included: fatigue, anxiety, stress, and patient-provider relationship, and quality of life. Clinics with primarily conventional health practitioners were less likely to address overall well-being (p = 0.04), while clinics that provided care to a specialized patient population (i.e. cancer patients) or a mix of general and specialized patients were less likely to address religious practices (p = 0.04) or spiritual experiences (p = 0.007). CONCLUSIONS: Outcomes across health domains should be considered in the evaluation of IHC models to generate an understanding of the full scope of effectiveness of IHC approaches. The core set of outcomes identified may facilitate this task. Ethics approval (Ethics ID REB14-0495) was received from the Conjoint Health Research Ethics Board at the University of Calgary.

Research Priorities of the Pediatric Spinal Cord Injury Population: An International Insight for Rehabilitation Care.

BACKGROUND: Although feedback from people with adult-onset spinal cord injury (SCI) has been considered for new rehabilitation programs, little is known about the priorities of the pediatric-onset SCI population. This study describes and compares health and life (H&L) domain research priorities of youth with pediatric-onset SCI and their parents/caregivers. METHODS: A cross-sectional survey, designed by the Pan-European Paediatric Spinal Cord Injury (PEPSCI) Collaboration, was performed at six European countries. Dyad data from 202 participants, youth with pediatric-onset SCI (n = 101) and their parents/caregivers (n = 101), were analyzed with the PEPSCI H&L domain surveys. RESULTS: The cohort was composed of 8 to 12-year-olds (30.7%), 13 to 17-year-olds (38.6%), and 18 to 25-year-olds (30.7%). The top three H&L domain research priorities reported by parents/caregivers of 8 to 12-year-olds were "walking/ability to move" (91%), "bladder" function (90%), and "general health/feel" (89%), compared with "physical function" (93%), "general health/feel" (90%), and "walking/ability to move" (89%) rated by parents/caregivers of 13 to 25-year-olds. "Bowel" function (85%), "leg/foot movement" (84%), and "bladder" function (84%) were reported as priorities by 13 to 25-year-olds, whereas "physical function" (84%), "experience at school" (83%), and "general mood" were highlighted by 8 to 12-year-olds. The top 10 priorities preferred by 13 to 25-year-olds when compared with the top 10 priorities reported by their parents/caregivers, included problems related to "bowel" and "pain." CONCLUSIONS: Health domain research priorities were highlighted by 13 to 25-year-olds, compared with their parents/caregivers who equally identified H&L domains. This survey will aid health care and clinical research organizations to engage stakeholders to implement a comprehensive research strategy for the pediatric SCI population.

Corrigendum: Examining human-animal interactions and their effect on multidimensional frailty in later life: a scoping review.

[This corrects the article DOI: 10.3389/fpubh.2023.1214127.].

Examining human-animal interactions and their effect on multidimensional frailty in later life: a scoping review.

This scoping review sought to compile outcomes associated with any human-animal interaction study regarding adults aged 50 and older in any living context and concerning a multidimensional (i.e., physical, psychological, cognitive, and social) perspective of frailty. Despite our best attempts at incorporating the broadest inclusion criteria possible, only four articles were relevant to this review. Participants across the included studies were rural, community-dwelling Japanese or Chinese individuals aged 60 years and older. Thematic analysis of reported results includes dog ownership as a protective factor regarding frailty, the interconnected health effects of pet ownership, and increased meaning and purpose through pet ownership implications. More research is needed globally to determine how human-animal interactions may moderate frailty comprehensively, as well as the efficacy and appropriateness of these interactions or interventions in older adult populations and across cultural boundaries.

Domain-Specific Common Data Elements for Rare Disease Registration: Conceptual Approach of a European Joint Initiative Toward Semantic Interoperability in Rare Disease Research.

BACKGROUND: With hundreds of registries across Europe, rare diseases (RDs) suffer from fragmented knowledge, expertise, and research. A joint initiative of the European Commission Joint Research Center and its European Platform on Rare Disease Registration (EU RD Platform), the European Reference Networks (ERNs), and the European Joint Programme on Rare Diseases (EJP RD) was launched in 2020. The purpose was to extend the set of common data elements (CDEs) for RD registration by defining domain-specific CDEs (DCDEs). OBJECTIVE: This study aims to introduce and assess the feasibility of the concept of a joint initiative that unites the efforts of the European Platform on Rare Disease Registration Platform, ERNs, and European Joint Programme on Rare Diseases toward extending RD CDEs, aiming to improve the semantic interoperability of RD registries and enhance the quality of RD research. METHODS: A joint conference was conducted in December 2020. All 24 ERNs were invited. Before the conference, a survey was communicated to all ERNs, proposing 18 medical domains and requesting them to identify highly relevant choices. After the conference, a 3-phase plan for defining and modeling DCDEs was drafted. Expected outcomes included harmonized lists of DCDEs. RESULTS: All ERNs attended the conference. The survey results indicated that genetic, congenital, pediatric, and cancer were the most overlapping domains. Accordingly, the proposed list was reorganized into 10 domain groups and recommunicated to all ERNs, aiming at a smaller number of domains. CONCLUSIONS: The approach described for defining DCDEs appears to be feasible. However, it remains dynamic and should be repeated regularly based on arising research needs.

Patient Reported Outcomes Measurements Information System in Stroke Patients in Full and Shortened Format.

Introduction: The modified Rankin Scale (mRS) after 90 days documents outcome in stroke patients, but focusses only on activities of daily living. Here we studied stroke outcome beyond these activities by the Dutch-Flemish version of the Patient Reported Outcomes Measurement Information System (PROMIS) questionnaire. Patients and Methods: We documented the mRS at day 90 in stroke patients who filled out a questionnaire on pain intensity and seven PROMIS domains: physical function, ability to participate in social roles, anxiety, fatigue, depression, sleep disturbance, pain interference. In a subgroup of patients this questionnaire was reduced to one overall question per PROMIS domain. We correlated these findings with the mRS. Results: We received 102 questionnaires and identified physical function as the most affected PROMIS domain. The strongest correlation with mRS was found for the health domains of physical function (ρs = 0.70, p < 0.001) and ability to participate in social roles (ρs = 0.61, p < 0.001). The other domains with substantial proportions of patients with worse scores compared to the general population (19-44%) correlated weakly with the mRS. We identified a strong correlation between the single question per health domain and the overall score per PROMIS domain. Discussion and Conclusion: PROMIS better reflects the overall health status of stroke patients beyond functional outcome as measured by the mRS. Simplification of the questionnaire with a single question per PROMIS domain could potentially replace the full questionnaire, but needs further validation.

Patient-Reported Outcomes in Rheumatoid Arthritis.

Patient-reported outcomes (PROs) and their measures have a long and important history for determining the status and treatment of patients with rheumatoid arthritis (RA). This article describes the history and evolution of PROs for RA and the current state of the field, with key examples of accepted and widely used measures, and offers some reflection on the roles of PROs for the study and management of RA.

Depression symptom trends and health domains among lung cancer patients in the CanCORS study.

OBJECTIVES: Among lung cancer patients depression symptoms are common and impact outcomes. The aims of this study were to determine risk factors that contribute to persistent or new onset depression symptoms during lung cancer treatment, and examine interactions between depression symptoms and health domains that influence mortality. MATERIALS AND METHODS: Prospective observational study in five healthcare systems and 15 Veterans Affairs medical centers. Patients in the Cancer Care Outcomes Research and Surveillance (CanCORS) Consortium with lung cancer were eligible. The 8-item Center for Epidemiologic Studies Depression (CES-D) scale was administered at baseline and follow-up. Scores ≥4 indicated elevated depressive symptoms. Health domains were measured using validated instruments. We applied logistic regression and Cox proportional hazards modeling to explore the association between depression symptoms, health domains, and mortality. RESULTS: Of 1790 participants, 38% had depression symptoms at baseline and among those still alive, 31% at follow-up. Risk factors for depression symptoms at follow-up included younger age (OR=2.81), female sex (OR=1.59), low income (OR=1.45), not being married (OR=1.74) and current smoking status (OR=1.80); high school education was associated with reduced odds of depression symptoms at follow-up, compared with lesser educational attainment (OR=0.74) (all p values <0.05). Patients with depression symptoms had worse health-related quality of life, vitality, cancer-specific symptoms, and social support than patients without depression symptoms (all p<0.001). The association between depression symptoms and increased mortality is greater among patients with more lung cancer symptoms (p=0.008) or less social support (p=0.04). CONCLUSIONS: Patient risk factors for depression symptoms at follow-up were identified and these subgroups should be targeted for enhanced surveillance. Patients with depression symptoms suffer across all health domains; however, only more lung cancer symptoms or less social support are associated with worse mortality among these patients. These potentially modifiable health domains suggest targets for possible intervention in future studies.

Health domains and race in generic preference-based health-related quality of life instruments in the United States literature / Domínios de saúde e raça nas medidas genéricas de qualidade de vida associada à saúde na literatura dos Estados Unidos / Dominios de salud y raza en las medidas genéricas de calidad de vida, asociada a la salud, en la literatura de los Estados Unidos

Race differences in health have been extensively analyzed and documented in the literature, especially between African Americans or blacks and whites in the United States. Despite the vast literature in the area, the majority of studies that explore the relationship between race and health use outcomes such as self-rated health, mortality or morbidity, and disability, but very few use Health-Related Quality of Life (HRQoL) measures and their domains or dimensions. This narrative review aims to provide a better understanding of the relationship between race and health domains that are commonly used in preference-based HRQoL measures. We investigated the literature on race, physical health, mental health, pain and discomfort, cognition, neurologic spectrum domains, dexterity, ambulation, vitality and social functioning domains. We conducted a literature search and review using the key words race and the health domain of interest, using medical and social sciences databases, such as MEDLINE/Pubmed, Web of Science, and the Google Scholar portal.The majority of the studies identified in the literature show that African Americans or blacks in the United States tend to have lower scores than whites throughout a variety of health domains found in preference-based HRQoL measures. This review also emphasizes the scarcity of studies that investigate some health domains, such as social functioning, dexterity, vitality and neurologic spectrum domains, and therefore we identify the need for more studies focusing on race and measures that address such domains.

A literatura sobre raça nos Estados Unidos está repleta de estudos que documentam diferenças na saúde entre negros e brancos. Entretanto, a maioria dos trabalhos que exploram a relação entre raça e saúde utiliza medidas com saúde autorrelatada, mortalidade e morbidade, mas poucos empregam medidas de qualidade de vida relacionada à saúde e seus domínios específicos. Este artigo revisa a literatura sobre raça e qualidade de vida relacionada à saúde, especificamente examinando os domínios que constituem as principais medidas baseadas na teoria da utilidade: saúde física; saúde mental; dor e desconforto; cognição; domínios neurológicos; destreza; locomoção; vitalidade; e funcionamento social. Conduziu-se uma revisão da literatura usando as palavras-chave raça e o domínio da qualidade de vida de interesse nos Estados Unidos. Foram consultadas as bases de dados Medline/Pubmed, Web of Science e o portal Google Scholar. A maioria dos estudos sobre diversos domínios das medidas de qualidade de vida investigados sugere que negros têm pior qualidade de vida do que brancos nos Estados Unidos. A revisão salienta a escassez de estudos que exploram a relação entre raça e alguns domínios, como, por exemplo, funcionamento social, destreza, vitalidade e domínios de escopo neurológico, e, portanto, mostra a necessidade de que futuros estudos examinem a relação entre raça e estes domínios.
