RESUMEN

How do people compare the effectiveness of different social-distancing behaviors in avoiding the spread of viral infection? During the COVID pandemic, we showed 676 online respondents in the United States, United Kingdom, and Israel 30 pairs of brief videos of acquaintances meeting. We asked respondents to indicate which video from each pair depicted greater risk of COVID infection. Their choices imply that on average, respondents considered talking 14 min longer to be as risky as standing 1 foot closer, being indoors as standing 3 feet closer, being exposed to coughs or sneezes as 3 to 4 ft closer, greeting with a hug as 7 ft closer, and with a handshake as 5 ft closer. Respondents considered properly masking as protecting the wearer and interlocutor equally, removing the mask entirely or only when talking as standing 4 to 5 ft closer but wearing it under the nose as only 1 to 2 ft closer. We provide weaker evidence on beliefs about the interaction effects of different behaviors. In a more limited, ex post analysis, we find little evidence of differences in beliefs across subpopulations.

RESUMEN

Behavioral responses influence the trajectories of epidemics. During the COVID-19 pandemic, nonpharmaceutical interventions (NPIs) reduced pathogen transmission and mortality worldwide. However, despite the global pandemic threat, there was substantial cross-country variation in the adoption of protective behaviors that is not explained by disease prevalence alone. In particular, many countries show a pattern of slow initial mask adoption followed by sharp transitions to high acceptance rates. These patterns are characteristic of behaviors that depend on social norms or peer influence. We develop a game-theoretic model of mask wearing where the utility of wearing a mask depends on the perceived risk of infection, social norms, and mandates from formal institutions. In this model, increasing pathogen transmission or policy stringency can trigger social tipping points in collective mask wearing. We show that complex social dynamics can emerge from simple individual interactions and that sociocultural variables and local policies are important for recovering cross-country variation in the speed and breadth of mask adoption. These results have implications for public health policy and data collection.

RESUMEN

BACKGROUND: Elective genomic testing (EGT) is increasingly available clinically. Limited real world evidence exists about attitudes and knowledge of EGT recipients. METHODS: After web-based education, patients who enrolled in an EGT program at a rural nonprofit healthcare system completed a survey that assessed attitudes, knowledge, and risk perceptions. RESULTS: From August 2020 to April 2022, 5,920 patients completed the survey and received testing. Patients most frequently cited interest in learning their personal disease risks as their primary motivation. Patients most often expected results to guide medication management (74.0%), prevent future disease (70.4%), and provide information about risks to offspring (65.4%). Patients were "very concerned" most frequently about the privacy of genetic information (19.8%) and how well testing predicted disease risks (18.0%). On average, patients answered 6.7 of 11 knowledge items correctly (61.3%). They more often rated their risks for colon and breast cancers as lower rather than higher than the average person, but more often rated their risk for a heart attack as higher rather than lower than the average person (all p<0.001). CONCLUSION: Patients pursued EGT because of the utility expectations, but often misunderstood the test's capabilities.

RESUMEN

BACKGROUND: Police and security presence in healthcare settings have grown. There are few studies exploring perceptions of these law enforcement agents among US Latine immigrants, who can be vulnerable to immigration enforcement actions due to past and ongoing criminalization and anti-immigrant policies. OBJECTIVE: To explore Latine immigrants' perceptions of law enforcement in healthcare settings. DESIGN: Exploratory, semi-structured qualitative interviews asked participants about their perspectives of law enforcement in healthcare settings. PARTICIPANTS: English- and Spanish-speaking adult patients (n = 19) from a Federally Qualified Health Center (FQHC) in Los Angeles, CA, serving predominantly low-income Latine immigrants. APPROACH: We used the framework method for analysis to establish a codebook and inform our thematic interpretation. KEY RESULTS: We identified three themes: (1) perceptions of safety offered by police officers are separated from the role of immigration officers; (2) perceptions of police officers are integrated into broader perceptions of the healthcare system; and (3) lived experiences, including immigration status, influenced valence response to officer uniforms and perceptions of officers. Most participants viewed police officers positively as maintaining order and safety, separating them from federal immigration enforcement actions, and reflecting on local, state, and organizational "sanctuary" or immigrant-friendly policies. Individuals with precarious immigration status more often saw officers as intimidating. Immigration enforcement remained a key concern. CONCLUSIONS: Differentiating police and security roles from immigration enforcement in healthcare could improve Latine immigrant trust and access. Future studies should explore perspectives of Latine immigrants in localities without sanctuary laws or organizational immigrant-friendly policies.

RESUMEN

BACKGROUND: Men with breast cancer experience unique physical and emotional challenges. However, a thorough understanding of these experiences including the psychosocial effects and supportive care needs have received less attention. In some settings, men with breast cancer experience stigma within the healthcare system and their care needs are not prioritised. This influences the level of professional support offered, consequently worsening their health and well-being outcomes. This review explored the variabilities in the experiences and treatment modalities of male breast cancer (MBC) across different contexts. METHODS: All primary study designs including qualitative, quantitative, and mixed methods studies that reported on the experiences, treatment approaches and outcomes of MBC were included in this systematic review. Six databases (Embase, Medline, PsycINFO, Global Health, CINAHL and Web of Science) were searched for articles from January 2000 to September 2023. A results-based convergence synthesis was used for data analysis and reported using PRISMA guidelines. RESULTS: Of the studies screened (n = 29,687), forty-four fulfilled the predetermined criteria and were included. Our findings relating to the experiences and treatment approaches of MBC are broadly themed into three parts. Theme 1-Navigating through a threat to masculinity: describes how males experienced the illness reflecting on detection, diagnosis, coming to terms with breast cancer, and disclosure. Theme 2- Navigating through treatment: captures the experiences of undergoing breast cancer treatment/ management following their diagnosis. Theme 3-Coping and support systems: describes how MBC patients coped with the disease, treatment process, aftercare/rehabilitative care, and the available support structures. CONCLUSIONS: Men experience a myriad of issues following a breast cancer diagnosis, especially with their masculinity. Awareness creation efforts of MBC among the public and healthcare practitioners are urgently required, which could change the perception of men in promoting early diagnosis, adherence to treatments, post-treatment monitoring, oncological results and a better quality of life. Considerations for training, education and development of specialised guidelines for healthcare practitioners on MBC would provide the necessary knowledge and skills to enhance their practice through the adoption of person-centred and male-specific care strategies. Professional care intervention and support for MBC should not end after the diagnosis phase but should extend to the entire treatment continuum and aftercare including future research focusing on MBC specific clinical trials. TRIAL REGISTRATION: PROSPERO Registration No. CRD42021228778.

RESUMEN

BACKGROUND: Athletes are a key group from which likely eligible donors could be sourced. While blood donation has been popularized as detrimental to athletic performance, little is known about how athletes perceive blood donation. The aim of this study was to investigate athletes' perceptions of the impacts of donating blood on their athletic performance and whether these influence their engagement with blood donation. STUDY DESIGN AND METHODS: A total of 175 athletes (78 donors; 97 non-donors) prescreened as eligible to donate blood in Australia completed an online survey assessing the perceived impact of (i) donating blood on engagement and performance in physical activity (type of impact, direction, and duration) and (ii) engaging in physical activity on blood donation (magnitude of impact and modification of behavior). RESULTS: We found that 37%-39% of our sample indicated that they had considered the impact of donating blood on their engagement or performance in physical activity, with the impact seen as negative but short term. Fatigue was the most commonly identified impact of donation on performance in physical activity. While the impact of donating did not account for athletes' non-donor status, many donors noted changing their engagement in physical activity pre- and post-donation to allow recovery, and aligning blood donation with their training schedule. DISCUSSION: Athletes are a key community from which likely eligible donors could be sourced, however a significant proportion of athletes perceive that donating will negatively impact their athletic performance. Strategies to engage athletes with donation should acknowledge and facilitate athletes need to align their training with donating.

RESUMEN

BACKGROUND: In Australia, a man cannot donate blood if he has had sex with another man within the past 3 months. However, this policy has been criticized as being discriminatory as it does not consider lower risk subgroups, and led to calls for modifications to the policy that more accurately distinguish risk among gay, bisexual, and other men who have sex with men (GBM). STUDY DESIGN AND METHODS: We used data from a nationally representative survey to estimate the proportion of GBM aged 18-74 years old who would be eligible to donate under current criteria and other scenarios. RESULTS: Among the 5178 survey participants, 155 (3.0%) were classified as GBM based on survey responses, Among the GBM, 40.2% (95% CI 28.0%-53.7%) were eligible to donate based on current criteria, and 21.0% (95% CI 14.5%-29.5%) were ineligible due to the 3 months deferral alone. Eligibility among GBM, all men, and the population increased as criteria were removed. Under the new Australian plasma donation criteria, 73.6% (95% CI 64.4%-81.1%) of GBM, 68.4% (95% CI 65.5%-71.2%) of all men, and 60.8% (95% CI 58.8%-62.8%) of the full population were estimated to be eligible. Only 16.1% (95% CI 8.6%-28.1%) of GBM knew that the male-to-male sex deferral period is 3 months. DISCUSSION: Changing the deferral criteria and sexual risk evaluation would lead to a higher proportion of GBM being eligible to donate blood. Knowledge of the current GBM deferral period is very low. Improved education about the current criteria and any future changes are required to improve blood donation rates.

RESUMEN

INTRODUCTION: Scabies is an underdiagnosed skin infestation caused by the Sarcoptes scabiei mite. The infection causes severe itching and a skin rash but can be effectively treated using topical or systemic drugs. Scabies outbreaks are commonly reported in resource-poor countries, including Ghana. Traditional healers play an important role in primary care in rural areas. The role of these traditional healers in the management of scabies has so far not been explored. The aim of this study was therefore to investigate the perceptions of traditional healers regarding the causation and management of scabies. METHODS: A phenomenological qualitative approach was employed. Traditional healers in the Asante Akim North and Central districts in Ghana were approached with an interview request. Using a semi-structured interview protocol, 15 traditional healers were interviewed. The results were coded and analysed, after which seven themes were extrapolated. RESULTS: Scabies infections were frequently reported by traditional healers. Itching and skin rash were unanimously regarded as the major symptoms of scabies. The majority acknowledged the infectious nature of scabies, but no participant reported the causative organism. A dichotomous disease classification was noted, consisting of 'natural' and 'spiritual' variants each with a unique disease profile and management requirements, as reported by the traditional healers. All but two traditional healers reported to treat scabies using almost exclusively herbs and spiritual rituals. CONCLUSION: The majority of traditional healers were open to collaboration with allopathic healthcare providers. Collaboration could broaden the primary care network in rural areas, but mistrust and lack of transparency form potential barriers to collaboration. We, therefore, emphasise the need for additional efforts to investigate strategies for future collaboration.

RESUMEN

Restless legs syndrome is a prevalent, sensorimotor sleep disorder temporarily relieved by movement, with evidence of symptomatic improvement with regular exercise. The present study describes perceptions of the effects of exercise on symptoms of restless legs syndrome. Participants (N = 528) completed a mixed-methods (i.e. numerical and narrative), nationwide survey including items assessing personal experiences with exercise and restless legs syndrome (both positive and negative), as well as restless legs syndrome diagnosis, restless legs syndrome severity, and demographic and clinical characteristics. Responses varied widely on specific experiences with exercise, but a higher percentage of participants indicated positive experiences with exercise than those who reported negative experiences (72%-40%, respectively) with exercise. Further, 54% of respondents reported that exercise only improves restless legs syndrome, while 24% reported exercise only worsens symptoms. Participants described that any abrupt change in exercise routine would almost always elicit restless legs syndrome symptoms (e.g. hiking for a long time, stopping an exercise routine), and that a consistent pattern of exercise improved restless legs syndrome symptoms with an overall beneficial effect on the frequency of symptomatic bouts. Participants further described time of day as impactful for their exercise experience, with > 50% indicating morning exercise improves symptoms and evening exercise worsens symptoms. Participants described several questions that they wanted answered regarding the evidence for exercise in restless legs syndrome and specific exercise prescription recommendations. The present study describes information crucial to the creation of stakeholder-informed health promotion programs for individuals with restless legs syndrome to optimize personalized treatment plans that could prevent and manage symptoms.

RESUMEN

OBJECTIVE: In paediatric oncology, little is known about trajectories of illness perceptions and their longitudinal associations with health-related quality of life (HRQoL). Therefore, the aim of this study was to investigate changes in illness perceptions in children and parents over a one-year-period and to investigate predictive value of child's and parent's illness perceptions during acute treatment for child's HRQoL 1 year later. METHODS: N = 65 child-parent-dyads participated in a longitudinal study (retention rate: 80.2%). Children were 4-18 years of age and underwent acute cancer treatment at baseline. Children and parents reported on their own illness perceptions (Illness-Perception-Questionnaire-Revised), as well as on the child's HRQoL (KINDL-R) at baseline and one-year-follow-up. Paired-samples t-tests were calculated to investigate changes over time. A hierarchical multiple regression analysis was performed to investigate predictive value of child's and parent's illness perceptions for child's HRQoL. RESULTS: Child's HRQoL t(63) = -6.73, p < 0.001, their perceptions of coherence (i.e. understanding; t(54) = -2.36, p = 0.022) and consequences of their illness (t(54) = 2.86, p = 0.006), and parent's perception of cyclical trajectory (t(61) = 2.06, p = 0.044) improved from baseline to 1-year-follow-up. All other illness perceptions remained stable. Exploratory post-hoc analyses showed differences in the pattern of change in age-, gender-, and diagnosis-specific subgroups. After controlling for baseline levels of HRQoL, child's perceptions of symptoms and consequences were independent predictors of their HRQoL 1 year later (R2 = 0.396, F(2,52) = 10.782, p < 0.001), whereas no parent's illness perceptions added predictive value. CONCLUSION: In paediatrics, child's and parent's illness perceptions should be assessed. Our findings highlight the importance of illness perceptions as potential modifiable variables in interventions to improve child's HRQoL.

RESUMEN

BACKGROUND: Individuals confronting health threats may display an optimistic bias such that judgments of their risk for illness or death are unrealistically positive given their objective circumstances. PURPOSE: We explored optimistic bias for health risks using k-means clustering in the context of COVID-19. We identified risk profiles using subjective and objective indicators of severity and susceptibility risk for COVID-19. METHODS: Between 3/18/2020-4/18/2020, a national probability sample of 6,514 U.S. residents reported both their subjective risk perceptions (e.g., perceived likelihood of illness or death) and objective risk indices (e.g., age, weight, pre-existing conditions) of COVID-19-related susceptibility and severity, alongside other pandemic-related experiences. Six months later, a subsample (N = 5,661) completed a follow-up survey with questions about their frequency of engagement in recommended health protective behaviors (social distancing, mask wearing, risk behaviors, vaccination intentions). RESULTS: The k-means clustering procedure identified five risk profiles in the Wave 1 sample; two of these demonstrated aspects of optimistic bias, representing almost 44% of the sample. In OLS regression models predicting health protective behavior adoption at Wave 2, clusters representing individuals with high perceived severity risk were most likely to report engagement in social distancing, but many individuals who were objectively at high risk for illness and death did not report engaging in self-protective behaviors. CONCLUSIONS: Objective risk of disease severity only inconsistently predicted health protective behavior. Risk profiles may help identify groups that need more targeted interventions to increase their support for public health policy and health enhancing recommendations more broadly.


As we move into an endemic stage of the COVID-19 pandemic, understanding engagement in health behaviors to curb the spread of disease remains critically important to manage COVID-19 and other health threats. However, peoples' perceptions about their risk of getting sick and having severe outcomes if they do fall ill are subject to bias. We studied a nationally representative probability sample of over 6,500 U.S. residents who completed surveys immediately after the COVID-19 pandemic began and approximately 6 months later. We used a computer processing (i.e., machine learning) approach to categorize participants based on both their actual risk factors for COVID-19 and their subjective understanding of that risk. Our analysis identified groups of individuals whose subjective perceptions of risk did not align with their actual risk characteristics. Specifically, almost 44% of our sample demonstrated an optimistic bias: they did not report higher risk of death from COVID-19 despite having one or more well-known risk factors for poor disease outcomes (e.g., older age, obesity). Six months later, membership in these risk groups prospectively predicted engagement in health protective and risky behaviors, as well as vaccine intentions, demonstrating how early risk perceptions may influence health behaviors over time.

RESUMEN

INTRODUCTION: On most online platforms, just about anyone can disseminate plastic surgery (PS) content regardless of their educational or professional background. This study examines the general public's perceptions of the accuracy of online PS content and the factors that contribute to the discernment of credible information. METHODS: The Amazon Mechanical Turk crowdsourcing platform was used to survey adults in the United States. The survey assessed respondent demographics, health literacy (HL), and perceptions of online PS content accuracy. T-tests, Chi-square tests, and post hoc analyses with Bonferroni corrections assessed differences between HL groups. Multivariate linear regressions assessed associations between sociodemographic variables and perceptions of online content. RESULTS: In total, 428 (92.0%) of 465 complete responses were analyzed. The median age of respondents was 32 y (interquartile range: 29-40). Online sources were predominantly perceived to have a high degree of accuracy, with mean scores of various platforms ranging from 3.8 to 4.5 (1 = not accurate at all; 5 = extremely accurate). The low HL group perceived social media sites and review sites to be more accurate than the high HL respondents, particularly for Reddit (P = 0.004), Pinterest (P = 0.040), and Snapchat (P = 0.002). CONCLUSIONS: There is a concerning relationship between low HL and the perceptions of the accuracy of online PS sources. This study underscores the need for education campaigns, the development of trustworthy online resources, and initiatives to improve HL. By fostering a more informed public, individuals seeking PS can make better informed decisions.

RESUMEN

INTRODUCTION: Widespread misperceptions about nicotine may have unintended effects on public health. We examined associations between existing messages about nicotine or tobacco and beliefs about nicotine and reduced nicotine cigarettes (RNC). METHODS: 2962 U.S. 18-45-year-olds were randomized in a May 2022 web-based survey to view one of 26 text-based messages about tobacco or nicotine from three sources: ongoing research (n = 8), messages authorized by FDA for VLN cigarettes (n = 6), and FDA's "From Plant to Product to Puff" campaign (n = 12); six messages from FDA's campaign did not reference nicotine and were treated as the reference source. Analyses examined associations between messages, grouped by source and individually, with beliefs about nicotine and RNC addictiveness and harms. RESULTS: Relative to FDA messages that did not reference nicotine, all message sources were associated with greater odds of a correct belief about nicotine (Odds Ratios [ORs] = 1.40-1.87, p's < 0.01); VLN messages were associated with greater correct beliefs about RNC addictiveness (b = 0.23, p < .05). No campaign produced greater correct beliefs about RNC harms. At the individual level, only five messages were associated with a correct belief about nicotine (ORs = 2.12-2.56, p-values < .01), and one with correct beliefs about RNC harms (b = 1.09, p < .05), vs. the reference message. CONCLUSIONS: Few existing messages improved understanding of the risks of nicotine separately from the risks of combustible products. Communication research is needed to promote greater public understanding of nicotine while minimizing unintended effects on nicotine and tobacco use.

RESUMEN

OBJECTIVE: To investigate cross-sectional associations between loneliness and health, health behaviours, and perceptions in Finnish individuals with overweight or obesity (BMI ≥25 kg/m2). METHODS: We used baseline data from patients participating, in 2016-2022, in a real-life digital 12-month weight management program known as Healthy Weight Coaching. Patients completed several questionnaires such as those related to loneliness, healthcare resource utilization, physical activity, and life satisfaction. BMI was computed based on self-reported weight and height. In addition to investigating individual health variables, we studied the association between loneliness and factor-analysis-derived health and wellbeing clusters. RESULTS: Data were available from 2000 individuals (16.7% men, median age 48 years, median BMI 39.2 kg/m2). Altogether, 11.6%, 42.4%, and 46.0% reported feeling lonely, somewhat lonely, and not lonely, respectively. Feeling lonely was associated with higher BMI, greater healthcare resource utilization, lower life satisfaction, burdensomeness of life, more negative perceptions related to obesity and to the upcoming coaching, lower daytime energy, and reduced 20-min brisk walk results, a measure of functional capacity. Of the five factor-analysis-derived clusters, loneliness was adversely associated with "Life satisfaction" [lonely, 0.337 (0.270-0.421), p < 0.001; somewhat lonely, 0.545 (0.475-0.625), p < 0.001]. Moreover, loneliness associated with "Negative perceptions of obesity/daytime fatigue" [lonely, 4.627 (3.391-6.314), p < 0.001; somewhat lonely 2.021 (1.694-2.412), p < 0.001], and "Obesity/low physical activity" [lonely, 1.474 (1.105-1.966), p = 0.008; somewhat lonely, 1.220 (1.019-1.460), p = 0.030]. CONCLUSIONS: Loneliness had several untoward associations with health, health behaviours, and perceptions. Further research should explore the intricate relationship between obesity, loneliness, and physical and psychosocial health. TRIAL REGISTRATION: The trial is registered at clinicaltrials.cov (Clinical Trials Identifier NCT04019249).

RESUMEN

Metabolic disease is increasing in people with HIV (PWH) in South Africa, but little is known about self-perceptions of body size, health, and nutritional behavior in this population. We performed a cross-sectional analysis of individual-level data from the 2016 South Africa Demographic and Health Survey. This survey measured HIV serostatus and body mass index (BMI). We categorized participants into six BMI groups: 18.5-22 kg/m2, 22-25 kg/m2, 25-27.5 kg/m2, 27.5-30 kg/m2, 30-35 kg/m2, and ≥ 35 kg/m2 and stratified them by HIV serostatus. Our outcomes were self-reported (1) body size and (2) health status among all participants, and intake of (3) chips and (4) sugar-sweetened beverages (SSB) in PWH. We described these metrics and used multivariable regression to evaluate the relationship between the nutritional behaviors and BMI ≥ 25 kg/m2 in PWH only, adjusting for age, sex, educational attainment, and household wealth quintile. Of 6138 participants, 1163 (19.7%) were PWH. Among PWH, < 10% with a BMI 25-30 kg/m2, < 20% with a BMI 30-35 kg/m2 and < 50% with a BMI ≥ 35 kg/m2 self-reported as overweight or obese. PWH reported being in poor health at higher rates than those without HIV at each BMI category except ≥ 35 kg/m2. In adjusted models, SSB consumption was associated with BMI ≥ 25 kg/m2 (1.13 [1.01-1.25], t-statistic = 2.14, p = 0.033) in PWH. Perceptions of body size may challenge efforts to prevent weight gain in PWH in South Africa. SSB intake reduction should be further explored as a modifiable risk factor for obesity.

RESUMEN

BACKGROUND: Following a stroke, patients may suffer from alterations in the perception of their own body due to an acquired deficit in body representations. While such changes may impact their quality of life as well as recovery, they are not systematically assessed in clinical practice. This study aims at providing a better understanding of the rate, evolution, and impact on recovery of upper limb (UL) body perceptions (BPs) alterations following stroke. In addition, we will investigate associations among BPs alterations items, their associations with the sensorimotor functions, UL activity, damages in brain structure and connectivity. METHODS: We developed a new tool named ALPQ (for Affected Limb Perception Questionnaire) to address the present study objectives. It assesses subjective alterations in the perception of the affected UL following stroke, by measuring several dimensions, namely: anosognosia for hemiplegia, anosodiaphoria for hemiplegia, hemiasomatognosia, somatoparaphrenia, personification of the affected limb, illusion of modification of physical characteristics (temperature, weight, length), illusory movements, super- or undernumerary limb, UL disconnection, misoplegia, and involuntary movement. This study combines a cross-sectional and longitudinal design. The completed data sample will include a minimum of 60 acute and 100 sub-acute stroke patients. When possible, patients are followed up to the chronic stage. Complementary evaluations are administered to assess patients' sensorimotor and cognitive functions as well as UL activity, and brain lesions will be analysed. DISCUSSION: This study will provide a better understanding of BPs alterations following stroke: their rate and evolution, as well as their associations with sensorimotor deficit, cognitive profile and UL activity, brain lesions and recovery. Ultimately, the results could support the personalization of rehabilitation strategy according to patients' UL perception to maximize their recovery. STUDY REGISTRATION: The protocol for this study has been pre-registered on the Open Science Framework on July the 7th, 2021: https://osf.io/p6v7f .

RESUMEN

BACKGROUND: While many patients with neurological disorders and conditions use complementary, alternative, and integrative medicine (CAIM), little is known about the use, perceptions, and attitudes regarding CAIM among published neurology authors. With the increasing popularity of CAIM, our objective was to assess practices, perceptions, and attitudes towards CAIM among published neurology authors. METHODS: We conducted an anonymous online survey of authors who had published articles in neurology journals indexed in MEDLINE. We emailed potential participants our cross-sectional electronic survey after extracting their email addresses from one of their publications in our sample of journals. Basic descriptive statistics were drawn from quantitative data, and thematic content analysis was used to analyse qualitative data from any open-ended questions. RESULTS: The survey was completed by 783 published neurology authors (1.7% response rate, 83.9% completion rate). Overall, respondents perceived CAIM to be promising in preventing, treating, and/or managing neurological diseases. Mind-body therapies received the most positive responses, indicated by over half of respondents cumulatively agreeing that they are promising (n = 368, 59.0%) and safe (n = 280, 50.3%). Whole medical systems and biofield therapy were less favourable. Most neurology clinicians reported a lack of formal (n = 211, 70.3%) and supplementary training (n = 158, 52.5%) on CAIM. Nearly half of clinicians did not feel comfortable counselling patients about CAIM therapies (n = 121, 44.5%), and over half did not feel comfortable recommending them (n = 161, 59.3%). A lack of scientific evidence for CAIM's safety and efficacy was reported as the greatest challenge to CAIM (n = 515, 92.5%). The majority of respondents believed there is value to conducting research on this topic (n = 461, 82.0%) and supported increasing allocation of research funding towards CAIM (n = 241, 58.9%). CONCLUSIONS: Although many participants found CAIM to be promising to the field of neurology, the vast majority did not feel open to integrating CAIM into mainstream medical practices on account of a perceived lack of scientific evidence for its safety and efficacy. Future studies can use our findings to gather more detailed insights, improve educational resources on CAIM within neurology, as well as examine what effects a tailored CAIM education has on the perceptions and attitudes of published neurology authors towards CAIM.

RESUMEN

Most protected area impact research that uses counterfactuals draws heavily on quantitative methods, data, and knowledge types, making it valuable in producing generalizations but limited in temporal scope, historical detail, and habitat diversity and coverage of ecosystem services. We devised a methodological pluralistic approach, which supports social science qualitative methods, narratives, mixed methods, and interdisciplinarity, to fully unlock the potential of counterfactuals in ensuring a place-based and detailed understanding of the socioecological context and impacts of protected areas. We applied this approach to derive possible counterfactual conditions for the impact of a montane protected area on 40 years of vegetation change in the Cape Floristic Region-a global biodiversity hotspot and UNESCO World Heritage Site in South Africa. We incorporated diverse methods, knowledge, and information sources, drawing on before-after protected area comparisons for inside and outside the protected area. A significant increase in shrubland vegetation (17-30%) was observed and attributed primarily to a decline in frequent burning for grazing. This also occurred outside the protected area and was driven by socioeconomic drivers and not by concerns over biodiversity conservation or land degradation. Had the protected area not been established the area would have seen intensification of cultivation and increased road networks, buildings, and water storage in dams. Our approach increased historical temporal coverage of socioecological change and contextualized assumptions around causality. Protected area impact evaluation should reengage in place-based research that fully incorporates pluralism in methodologies for constructing counterfactuals in a way that builds regional and global understanding from the local level upward. We devised 10 key principles for deriving counterfactuals grounded in methodological pluralism, covering aspects of collaboration, cocreation, inter- and transdisciplinarity, diverse values and lived experiences, multiple knowledge types, multiple possible causal mechanisms, social science qualitative methods, perceptions, perspectives, and narratives.


Importancia del pluralismo metodológico en la derivación de situaciones contrafactuales para la conservación basada en evidencias Resumen La mayoría de las investigaciones sobre el impacto de las áreas protegidas que usan situaciones contrafactuales se basan en gran medida en métodos cuantitativos, datos y tipos de conocimiento, por lo que son muy valiosas para producir generalizaciones, pero limitadas en el enfoque temporal, el detalle histórico y la diversidad de hábitats y cobertura de los servicios ambientales. Diseñamos una estrategia metodológica pluralista, la cual apoya los métodos cualitativos de las ciencias sociales, narrativas, métodos mixtos e interdisciplinarios para utilizar por completo el potencial de las situaciones contrafactuales para asegurar un conocimiento detallado y basado en el lugar del contexto socio ecológico y el impacto de las áreas protegidas. Aplicamos esta estrategia para derivar las posibles condiciones contrafactuales del impacto de un área protegida montañosa sobre 40 años de cambio de vegetación en el reino florístico del Cabo ­ un punto caliente de biodiversidad y Sitio de Patrimonio Mundial de la UNESCO en Sudáfrica. Incorporamos varios métodos, conocimientos y fuentes de información a partir de las comparaciones antes­después dentro y fuera del área protegida. Observamos un incremento significativo en la vegetación del matorral (17­30%), el cual atribuimos principalmente en la disminución de la quema frecuente para el pastoreo. Esto también ocurrió fuera del área protegida y fue causado por factores socioeconómicos y no por preocupación por la conservación de la biodiversidad o por la degradación del suelo. De no haberse establecido el área protegida, la zona habría sufrido una intensificación de cultivos y un incremento de carreteras, edificios y almacenamiento de agua en presas. Nuestra estrategia incrementó la cobertura histórica temporal del cambio socio­ecológico y contextualizó las suposiciones sobre la causalidad. La evaluación del impacto del área protegida debe volver a la investigación basada en el lugar que incorpora de lleno el pluralismo en la metodología para construir situaciones contrafactuales de una forma que genere conocimiento regional y global a partir del nivel local y hacia arriba. Diseñamos diez principios clave para derivar las situaciones contrafactuales basados en el pluralismo metodológico, la cobertura de los aspectos de colaboración, creación conjunta, inter­ y transdisciplinariedad, valores diversos y experiencias vividas, varios tipos de conocimiento, diferentes mecanismos causales posibles, métodos cualitativos de las ciencias sociales, percepciones, perspectivas, historias y narrativas.

RESUMEN

BACKGROUND: Bats are a reservoir for many viruses causing haemorrhagic fevers. Proximity to bats is a risk factor for virus spillover to animals and humans. We conducted this study to assess knowledge, perceptions, and exposure to bats in communities living near bat roosts in Bundibugyo District, Uganda. METHODS: A cross-sectional study using mixed methods with both quantitative and qualitative data was conducted between September and December 2022. Participants for the quantitative data (survey) (n = 384) resided near bat caves and/or roost sites and were selected using multistage random sampling. The survey investigated participants' prior exposure to bats, as well as knowledge and perceptions of bat exposure. Logistic regression was used to determine factors associated with bat exposure. Participants for the qualitative data (focus group discussions) (n = 10, 6-8 participants each) were purposely selected based on engagement in guano mining, hunting, and farming activities. Perceived risk associated with bat-related activities were identified and ranked in the focus group discussions using participatory epidemiology tools. RESULTS: In total, (214/384, 55.7%) had a history of bat exposure and (208/384, 54.2%) had poor knowledge of risk factors associated with bat exposure. Increased exposure to bats was associated with being male (OR = 1.6; 95% CI: 1.0, 2.4 p-value = 0.038), staying in urban areas (OR = 1.9; p-value = 0.010), hunting (OR = 10.9; p-value = 0.024), and positive perception to bat guano being safe as fertiliser (OR = 2.5; p-value = 0.045). During the proportional piling process, a total of 7 risk factors were identified by 10 groups with hunting during an outbreak and consumption of bats being the most frequently identified. Overall, there was a strong statistical agreement in the ranking across the 10 focus groups (W = 0.52; p < 0.01; n = 10). Based on the provided data, the adjusted odds ratio of 0.7 for the good measures (p-value = 0.112), suggests a potential protective effect on the risk of bat exposure. CONCLUSION: Communities living around bat roosts frequently come into contact with bats, yet there is inadequate awareness regarding the behaviors that can lead to the transmission of bat- borne diseases to humans. It is essential to undertake educational initiatives and preventive measures to minimise the risks of bat-related infections. The need for targeted health communication and education efforts to address these knowledge gaps and promote an accurate understanding of bats and disease transmission. Understanding of diseases associated with bats will minimize bat-related health risks especially in communities engaged in wildlife hunting.

RESUMEN

INTRODUCTION: Heated tobacco products (HTPs), like IQOS, are marketed as innovative, stylish, harm-reduction products distinct from cigarettes and e-cigarettes. Research is needed to better understand how adults who are newly introduced to HTPs perceive them relative to cigarettes and e-cigarettes, and the impact of these perceptions on use outcomes. METHODS: We analyzed 2021 cross-sectional survey data from 1,914 adults who never used HTPs from the United States and Israel, two countries where IQOS has unique histories and markets. Exploratory factor analysis examined perceptions of HTPs (vs. cigarettes and e-cigarettes) across 12 perception measures (e.g., innovative, trendy, harmful, addictive). Multivariable linear regression examined these factors in relation to self-reported likelihood to: 1) "try HTPs in the next year" (1=not-7=extremely); and 2) "suggest IQOS to a friend who smokes cigarettes" (1=not-5=very), controlling for demographics and past-month cigarette and e-cigarette use (10.1% dual use, 15.4% cigarette-only, 5.7% e-cigarette-only, 68.8% neither). RESULTS: Four factors were identified: HTPs' health and utility ('health-utility') and design and appeal ('design-appeal') vs. cigarettes and vs. e-cigarettes, separately. More favorable perceptions of HTP vs. e-cigarette design-appeal (B=0.30, 95%CI=0.18, 0.41) was associated with greater likelihood to try HTPs. More favorable perceptions of HTP vs. cigarette design-appeal (B=0.38, 95%CI=0.26, 0.51) and health-utility (B=0.25, 95%CI=0.13, 0.36), and HTP vs. e-cigarette design-appeal (B=0.32, 95%CI=0.20, 0.45) were associated with greater likelihood to suggest HTPs to smokers. CONCLUSIONS: Monitoring perceptions of HTPs vs. cigarettes and e-cigarettes is critical given the role of such perceptions in HTP use and their population-level impact. IMPLICATIONS: This study examined the relationship of perceptions of HTPs relative to cigarettes and e-cigarettes, with regard to adults' self-reported likelihood to use HTP or to suggest HTPs to those who smoke cigarettes. Favorable perceptions of HTPs' design and appeal versus e-cigarettes correlated with greater likelihood to try HTPs. Favorable perceptions of HTPs' design and appeal, as well as health and utility, versus cigarettes and e-cigarettes correlated with greater likelihood to suggest HTPs to those who smoke. Findings underscore the need for ongoing surveillance of HTP marketing and consumer perceptions to inform regulatory efforts and estimate the population-level impact of HTPs and other tobacco products.
