Reduced ankle quasi-joint stiffness affects propulsion in the paretic side of patients with hemiparesis, contributing to gait asymmetry. We investigated whether the use of an ankle-foot orthosis with dorsiflexion resistance to compensate for reduced stiffness would increase quasi-joint stiffness and spatiotemporal symmetry in patients with hemiparesis. Seventeen patients walked along a 7-m walkway in both ankle-foot orthosis with dorsiflexion resistance and control (i.e., ankle-foot orthosis) conditions. Dorsiflexion resistance by spring and cam was set to increase linearly from zero-degree ankle dorsiflexion. Gait data were analyzed using a three-dimensional motion analysis system. Ankle-foot orthosis with dorsiflexion resistance significantly increased the quasi-joint stiffness in the early and middle stance phase (P = 0.028 and 0.040). Furthermore, although ankle power generation in the ankle-foot orthosis with dorsiflexion resistance condition was significantly lower than in the control condition (P = 0.003), step length symmetry significantly increased in the ankle-foot orthosis with dorsiflexion resistance condition (P = 0.016). There was no significant difference in swing time ratio between conditions. Applying dorsiflexion resistance in the paretic stance phase increased quasi-joint stiffness but did not lead to an increase in ankle power generation. On the other hand, applying dorsiflexion resistance also resulted in a more symmetrical step length, even though the ankle joint power generation on the paretic side did not increase as expected. Future research should explore whether modifying the magnitude and timing of dorsiflexion resistance, considering the biomechanical characteristics of each patients' ankle joint during gait, enhances ankle joint power generation.
Reducing excess population mortality caused by crises due to armed conflict and natural disasters is an existential aim of humanitarian assistance, but the extent to which these deaths are averted in different humanitarian responses is mostly unknown. This information gap arguably weakens governance and accountability. This paper considers methodological challenges involved in making inferences about humanitarian assistance's effect on excess mortality, and outlines proposed approaches. Three possible measurement questions, each of which contributes some inferential evidence, are presented: (1) whether mortality has remained within an acceptable range during the crisis (for which different direct estimation options are presented); (2) whether the humanitarian response is sufficiently appropriate and performant to avert excess mortality (a type of contribution analysis requiring in-depth audits of the design of humanitarian services and of their actual availability, coverage and quality); and (3) the actual extent to which humanitarian assistance has reduced excess deaths (potentially the most complex question to answer, requiring application of causal thinking and careful specification of the exposure, and for which either quasi-experimental statistical modelling approaches or a combination of verbal and social autopsy methods are proposed). The paper concludes by considering possible 'packages' of the above methods that could be implemented at different stages of a humanitarian response, and calls for investment in improved methods and actual measurement.
Reducing free sugars intake is important for the prevention of dental caries and obesity in children. The study aimed to determine the amount and sources of free sugars known to contribute to dental caries, and identify sociodemographic determinants of intake by children aged 5 years in Australia. Cross-sectional analysis of dietary data from a cohort study, collected using a customized food frequency questionnaire were used to calculate free sugars intake as grams/day and percentage contribution to Estimated Energy Requirement (EER). The percent contribution of food sources to free sugars intake was derived. Sociodemographic determinants of achieving intakes within WHO thresholds (i.e., <5% and <10% Energy were explored with multinomial logistic regression. Complete data were available for 641 children (347 boys, 294 girls). Median (IQR) free sugars intake (g/day) was 31.6 (21.3-47.6) in boys and 28.1 (19.6-47.9) in girls. The median (IQR) percentage contribution to EER was 7.9 (5.4-12.7); 21% and 42% of children had intakes <5% EER and between 5% and <10%, respectively. The main sources of free sugars were: (1) Cakes, Biscuits and Cereal Bars; (2) Sweetened Milk Products (predominantly yoghurts) and (3) Desserts. Maternal university education, single-parent household, and maternal place of birth being Australia or New Zealand were associated with free sugars intake <5% EER. In conclusion, less than a quarter of 5-year-old children in the SMILE cohort achieved the WHO recommendations to limit free sugars to <5% EER. Strategies to lower free sugars intake could target priority populations such migrants, populations with lower levels of education or health literacy and identify areas for intervention in the wider food environments that children are exposed to.
Reducing racial/ethnic and socioeconomic environmental health disparities requires a comprehensive multilevel conceptual and quantitative approach that recognizes the various levels through which environmental health disparities are produced and perpetuated. We propose a conceptual framework that incorporates the micro level, contained within the local level, which in turn is contained within the macro level. We discuss the utility of multilevel techniques to examine environmental level (both physical and social) and individual-level factors to appropriately quantify and improve our understanding of environmental health disparities. We discuss the reasoning and the methodological approach behind multilevel modeling, including differentiating between individual and contextual influences on individual outcomes. Next we address the questions and principles that guide the choice of levels or geographic units in multilevel studies. Finally, we address the ways in which different data sources can be combined to produce suitable data for multilevel analyses. We provide some examples of how such data sources can be linked to create multilevel data structures, and offer suggestions to facilitate the integration of multilevel techniques in environmental health disparities research and monitoring.
Reducing red meat consumption is a key strategy for curbing diet-related chronic diseases and mitigating environmental harms from livestock farming. Messaging interventions aiming to reduce red meat consumption have focused on communicating the animal welfare, health, or environmental harms of red meat. Despite the popularity of these 3 approaches, it remains unknown which is most effective, as limited studies have compared them side by side. Our aim was to evaluate responses to red-meat-reduction messages describing animal welfare, health, or environmental harms. This was an online randomized experiment. In August 2021, a convenience sample of US adults was recruited via an online panel to complete a survey (n = 2,773 nonvegetarians and vegans were included in primary analyses). Participants were randomly assigned to view 1 of the 4 following messages: control (neutral, non-red meat message), animal welfare, health, or environmental red-meat-reduction messages. After viewing their assigned message, participants ordered hypothetical meals from 2 restaurants (1 full service and 1 quick service) and rated message reactions, perceptions, and intentions. Logistic and linear regressions were performed. Compared with the control message, exposure to the health and environmental red-meat-reduction messages reduced red meat selection from the full-service restaurant by 6.0 and 8.8 percentage points, respectively (P = .02 and P < .001, respectively), while the animal welfare message did not (reduction of 3.3 percentage points, P = .20). None of the red-meat-reduction messages affected red meat selection from the quick-service restaurant. All 3 red-meat-reduction messages elicited beneficial effects on key predictors of behavior change, including emotions and thinking about harms. Red-meat-reduction messages, especially those describing health or environmental harms, hold promise for reducing red meat selection in some types of restaurants. Additional interventions may be needed to discourage red meat selection across a wider variety of restaurants, for example, by making salient which menu items contain red meat.
Reducing school energy costs has become an important issue, while the energy saving should consider different school systems and student backgrounds. This study investigated the impact of student demographics on energy consumption in elementary and secondary schools and explores the difference of energy consumption in different types and levels of school systems. Data were collected from 3672 schools (including 3108 elementary and 564 secondary schools, respectively) in Ontario, Canada. The number of students whose first language is not English, the number of students who receive special education services, the number of school-aged children who live in low-income households, and student learning ability are all inversely proportional to energy consumption; student learning ability has the largest negative impact. The partial correlation between student enrollment and energy consumption has a trend of gradually increasing as the grade levels increase in Catholic elementary schools, Catholic secondary schools, and public secondary schools; however, the correlation shows a gradually decreasing trend with the increase in grade levels in public elementary schools. This study is helpful for policy-makers to clarify the energy implications of various student backgrounds and the energy consumption difference in different types and levels of school systems to facilitate their formulation of effective policies.
Reducing unnecessary tests that do not enhance quality can promote health-care value. Glycated hemoglobin (A1C) is often ordered at a frequency exceeding the recommendation of once every 3 months. We conducted a quality improvement (QI) initiative aimed to reduce unnecessary repeat testing by 75% at a tertiary care academic hospital. A retrospective baseline analysis was conducted on laboratory data from 2019 that enumerated unnecessary A1C tests, defined as repeat tests ordered within 60 days. A multifaceted change intervention with iterative plan-do-study-act cycles was introduced in March 2019 to educate providers and to automatically cancel A1C tests requested within 60 days. Monthly totals of A1C testing processed were plotted on statistical process control charts. In 2019, 11% of all A1C tests ordered were unnecessary. Between March 2020 and January 2021, 11% of the tests (N=14,247 tests) were unnecessary, of which 84% were cancelled with our intervention. Providers in cardiology and nephrology accounted for over half (55%) of the unnecessary tests ordered. A 2-pronged approach informed by root-cause analysis, and comprised of gatekeeping and provider education, can effectively promote resource stewardship for reducing unnecessary A1C testing.
Reevaluating and expanding cochlear implantation's (CI) indication while measuring the quality of life (QoL) outcomes regarding the parent's point of view of prelingually deafened, late-implanted patients, which are widely known to showcases a limited improvement in speech recognition. A retrospective descriptive and analytic study to assess QoL outcomes from CI in 64 early deafened, late-implanted patients, according to their parent's perspective, between January 2009 and December 2019, using the Nottingham Pediatric Cochlear Implant Program (Nottingham University Hospital, Nottingham, United Kingdom) "Children with cochlear implantation: parents perspective." The most represented age interval is the 5 and 7 interval and the mean age is 10.09 years. There was no sex predominance, with rural origin and high school academicals level preponderance. Fourteen children had experienced neonatal icterus, eight had meningitis, and seven were the result of related marriage. The age of the first consultation was typically over 2 years old, with only 45 schooled children. Age had a significantly statistic correlation between Self-reliance and Well-being and happiness subscales. History of receiving aid and speech therapy has a clear correlation with Self-reliance, Well-being and happiness, and Communication and Education. Schooling statuses, sex, age of appearance, and communication mode were not correlated to any subscale score, and with the exception of Effect of implantation, all the other "Children with cochlear implantation: parent's perspective" subscales were intercorrelated. Properly validated QoL assessments for CI are a must, as outcomes of CI expand beyond audiometric performances to include the improvement of QoL.
Referral of a patient from one healthcare provider to another is an important part of the medical practice. The aim of this study was to analyze the referral process to the Oral Medicine Unit in a university-based tertiary center in Southern Italy. A chart review of new referrals to the Oral Medicine Unit during a 24-month period was conducted. The following data were recorded: demographic characteristics, medical history, number of physicians seen prior to Oral Medicine assessment, referral source, diagnostic procedures ordered by referrals, reason for referral, site of lesion/condition, final diagnosis. Then, the rates of correct identification for health-care professionals and the appropriateness of the reference diagnosis based on the disease were calculated with descriptive statistic indicators. There were 583 new first consultations. A total of 62.9% of patients were referred by general dental practitioners, 27.4% by physicians, and 9.7% did not have a referral. The most common diseases for referral were immune-mediated diseases (39.6%) and oro-facial pain disorders (25.2%). Only 28.5% of patients had a correct provisional diagnosis. The results of this study show the need to implement curricula in the field of oral medicine among dentistry and medical students, and to support the continuing education among healthcare providers to reduce diagnostic delay for oral diseases.
Reflective capacity is a prerequisite for transformative learning. It is regarded as an essential skill in professional competence in the field of medicine. Our aim was to investigate the reflective capacity and the objects of action (themes) which revealed reflective writing of medical students during a general practice/family medicine course. Second-year medical students were requested to write learning diaries during a compulsory course in general practice/family medicine consisting of the principles of the physician-patient relationship. The course included a group session supervised by a clinical lecturer and a 3-day training period in a local health centre. We conducted data-driven content analysis of the learning diaries. In the learning diaries, student observations were most commonly directed to events during the training period and to group sessions. Occasionally, observation was directed at inner experience. The following themes were related to reflective writing: feelings towards the end of life, demanding situations in practice, physician's attitude to patient, student's inner experiences, and physician's well-being. The entries indicated different types of reflective capacity. Three subgroups were identified: 'simple reporting,' 'reflective writing,' and 'advanced reflective writing.' Professional growth requires the development of reflective capacity, as it is essential for successful patient care and better clinical outcomes. To develop and enhance the reflective capacity of medical students during their education, the curriculum should provide frequent opportunities for students to assess and reflect upon their various learning experiences.
Refugee mothers are vulnerable to cultural stereotyping and socioeconomic hardships when they migrate to a new country. This vulnerability often has a negative impact on refugee mothers' breastfeeding practices. Saskatchewan is one of the growing provinces in Canada that has a noticeable increase in refugee population with young children and limited availability of healthcare settings with baby-friendly status. Considering existing gaps in knowledge, this critical ethnographic study aimed to explore barriers that impede the breastfeeding practices of refugee mothers in Saskatchewan. After seeking ethics approval, data were collected using multiple methods, including in-depth interviews undertaken with 27 refugee mothers with young children of age range 1 day to 24 months, a review of media communications and field observations of community-based services/facilities available to refugee mothers. Findings suggest that psychosocial barriers, healthcare barriers, environmental barriers, and maternal and child health-related barriers impede the breastfeeding practices of refugee mothers in Saskatchewan. Breastfeeding practices of refugee mothers can be promoted through healthcare support, culturally appropriate services, interpretation services in healthcare settings, implementation of baby-friendly initiatives, hospital and community-based breastfeeding campaigns, and follow-up services. Collaborative efforts by healthcare settings, healthcare providers, policymakers, public health agencies, service providers, and governments are essential to support the breastfeeding practices of refugee mothers.
Refugees and immigrants can experience complex stressors from the process of immigration that can have lasting and severe long-term mental health consequences. Experiences after ayahuasca ingestion are shown to produce positive effects on psychological wellbeing and mental health, including anecdotal reports of improved symptoms of trauma and related disorders. However, data on the longitudinal health impact of naturalistic ayahuasca use in Middle Eastern and North African (MENA) immigrant and refugee populations is limited. The current longitudinal online survey study was conducted to gather prospective data on ceremonial ayahuasca use in a group (N = 15) of primarily female MENA immigrants and refugees and to provide further insight into the patterns and outcomes surrounding that use. The study sought to assess self-reported changes in physical and mental health, well-being, and psychological functioning, examine relationships between aspects of individual mindset (e.g., psychedelic preparedness) prior to ayahuasca use and observed outcomes during (e.g., subjective drug effects) and afterwards (i.e., persisting effects), characterize risks and negative experiences, and describe trauma exposure and personal history. Our findings revealed ceremonial use of ayahuasca is associated with significant improvements in mental health, well-being, and psychological functioning, including reductions in depression, anxiety, and shame, and increases in cognitive reappraisal and self-compassion. Most participants reported no lasting adverse effects and experienced notable positive behavioral changes persisting months after ingestion. While preliminary, results suggest naturalistic ayahuasca use might hold therapeutic potential for MENA populations exposed to trauma prior to and during the process of migration.
Regional anaesthesia plays an important role in perioperative care, but gaps in proficiency persist among consultants and specialists. This study aimed to assess confidence levels in performing Plan A blocks among this cohort and to examine the barriers and facilitators influencing regional anaesthesia education. Utilising a mixed-methods design, we performed a quantitative survey to gauge self-reported confidence in performing Plan A blocks, coupled with qualitative interviews to explore the complexities of educational barriers and facilitators. UK consultant and specialist anaesthetists were included in the study. A total of 369 survey responses were analysed. Only 22% of survey respondents expressed confidence in performing all Plan A blocks. Specialists (odds ratio [OR] 0.391, 95% confidence interval [CI] 0.179-0.855, P=0.016) and those in their roles for >10 yr (OR 0.551, 95% CI 0.327-0.927, P = 0.024) reported lower confidence levels. A purposive sample was selected for interviews, and data saturation was reached at 31 interviews. Peer-led learning emerged as the most effective learning modality for consultants and specialists. Barriers to regional anaesthesia education included apprehensions regarding complications, self-perceived incompetence, lack of continuing professional development time, insufficient support from the multidisciplinary team, and a lack of inclusivity within the regional anaesthesia community. Organisational culture had a substantial impact, with the presence of local regional anaesthesia champions emerging as a key facilitator. This study highlights persistent perceived deficiencies in regional anaesthesia skills among consultants and specialists. We identified multiple barriers and facilitators, providing insights for targeted interventions aimed at improving regional anaesthesia education in this group.
Regional population management (PM) health initiatives require insight into experienced quality of care at the regional level. Unsolicited online provider ratings have shown potential for this use. This study explored the addition of comments accompanying unsolicited online ratings to regional analyses. The goal was to create additional insight for each PM initiative as well as overall comparisons between these initiatives by attempting to determine the reasoning and rationale behind a rating. The Dutch Zorgkaart database provided the unsolicited ratings from 2008 to 2017 for the analyses. All ratings included both quantitative ratings as well as qualitative text comments. Nine PM regions were used to aggregate ratings geographically. Sentiment analyses were performed by categorizing ratings into negative, neutral, and positive ratings. Per category, as well as per PM initiative, word frequencies (ie, unigrams and bigrams) were explored. Machine learning-naïve Bayes and random forest models-was applied to identify the most important predictors for rating overall sentiment and for identifying PM initiatives. A total of 449,263 unsolicited ratings were available in the Zorgkaart database: 303,930 positive ratings, 97,739 neutral ratings, and 47,592 negative ratings. Bigrams illustrated that feeling like not being "taken seriously" was the dominant bigram in negative ratings, while bigrams in positive ratings were mostly related to listening, explaining, and perceived knowledge. Comparing bigrams between PM initiatives showed a lot of overlap but several differences were identified. Machine learning was able to predict sentiments of comments but was unable to distinguish between specific PM initiatives. Adding information from text comments that accompany online ratings to regional evaluations provides insight for PM initiatives into the underlying reasons for ratings. Text comments provide useful overarching information for health care policy makers but due to a lot of overlap, they add little region-specific information. Specific outliers for some PM initiatives are insightful.
