ABSTRACT

This commentary represents a dialogue on key aspects of disease-related malnutrition (DRM) from leaders and experts from academia, health across disciplines, and several countries across the world. The dialogue illuminates the problem of DRM, what impact it has on outcomes, nutrition care as a human right, and practice, implementation, and policy approaches to address DRM. The dialogue allowed the germination of an idea to register a commitment through the Canadian Nutrition Society and the Canadian Malnutrition Task Force in the UN/WHO Decade of Action on Nutrition to advance policy-based approaches for DRM. This commitment was successfully registered in October 2022 and is entitled CAN DReaM (Creating Alliances Nationally for Policy in Disease-Related Malnutrition). This commitment details five goals that will be pursued in the Decade of Action on Nutrition. The intent of this commentary is to record the proceedings of the workshop as a stepping stone to establishing a policy-based approach to DRM that is relevant in Canada and abroad.

ABSTRACT

BACKGROUND: People experiencing homelessness (PEH) are disproportionately affected by many infectious diseases, including coronavirus disease 2019 (COVID-19). However, communication efforts during public health emergencies like the COVID-19 pandemic often do not consider the unique needs of PEH. We examined how PEH seek and receive health information and how traditional health communication methods resonate with them. METHODS: We conducted in-person focus groups with PEH in 4 jurisdictions (Cincinnati, Ohio; Denver, Colorado; Sacramento, California; and the Bronx, New York) during July 2021. RESULTS: Findings from 15 focus groups with PEH (n = 53) revealed the need for trusted messengers and consistent messaging across local organizations, as PEH seek to verify information they receive from multiple sources. PEH overwhelmingly preferred to receive health information through face-to-face conversations, especially with healthcare providers with whom they had an established relationship, but they also cited news media, the internet, and social media as their main sources for obtaining health information. PEH reported that effective communication products pair a recommended action with instructions and resources about how to take that action within their community. CONCLUSIONS: These findings support healthcare providers collaborating with public health agencies to ensure that infectious disease prevention messages for PEH are provided by trusted messengers, multimodal, paired with resources, and consistent.

ABSTRACT

Nearly all young people use the internet daily. Many youth with mental health concerns, especially since the Covid-19 pandemic, are using this route to seek help, whether through digital mental health treatment, illness prevention tools, or supports for mental wellbeing. Videogames also have wide appeal among young people, including those who receive mental health services. This review identifies the literature on videogame interventions for young people, ages 12-29, and maps the data on game use by those with mental health and substance use problems, focusing on evidence for the capacity of games to support treatment in youth mental health services; how stakeholders are involved in developing or evaluating games; and any potential harms and ethical remedies identified. A systematic scoping review methodology was used to identify and assess relevant studies. A search of multiple databases identified a total of 8,733 articles. They were screened, and 49 studies testing 32 digital games retained. An adapted stepped care model, including four levels, or steps, based on illness manifestation and severity, was used as a conceptual framework for organizing target populations, mental health conditions and corresponding digital games, and study results. The 49 selected studies included: 10 studies (20.4%) on mental health promotion/prevention or education for undiagnosed youth (Step 0: 7 games); 6 studies (12.2%) on at-risk groups or suspected mental problems (Step 1: 5 games); 24 studies (49.0%) on mild to moderate mental conditions (Steps 2-3: 16 games); and 9 studies (18.4%) focused on severe and complex mental conditions (Step 4: 7 games). Two interventions were played by youth at more than one level of illness severity: the SPARX game (Steps 1, 2-3, 4) and Dojo (Steps 2-3 and 4), bringing the total game count to 35 with these repetitions. Findings support the potential integration of digital games in youth services based on study outcomes, user satisfaction, relatively high program retention rates and the potential usefulness of most games for mental health treatment or promotion/prevention. Most studies included stakeholder feedback, and involvement ratings were very high for seven games. Potential harms were not addressed in this body of research. This review provides an important initial repository and evaluation of videogames for use in clinical settings concerned with youth mental health.

ABSTRACT

INTRODUCTION: Chronic pelvic pain affects 15-20% of women, and patients frequently do not find relief with first-line therapies. Mindfulness-based meditation programs are effective in improving outcomes for patients with chronic pain conditions, but limited data exists for patients with chronic pelvic pain. We describe the effect of a brief mindfulness-based program, incorporated into pelvic-floor physical therapy visits, on perceived pain in patients with chronic pelvic pain. CASE SERIES: Patients being treated for pelvic pain participated in this 8-week program. Pelvic-floor physical therapists delivered a brief mindfulness-based exercise during routine physical therapy visits. Patients reported pain scores and pain catastrophizing scores at the beginning and end of the program. Ten patients completed the program. Paired-samples t-tests showed that pain catastrophizing significantly decreased from baseline to 8 weeks in patients who completed the mindfulness training and increased among patients who withdrew. CONCLUSION: Mindfulness-based exercises may be a useful complementary therapy for the treatment of chronic pelvic pain.

ABSTRACT

Often portrayed as a harmless leisure activity in the UK, gambling is being increasingly recognised as a public health concern. However, a gambling policy system that explicitly tackles public health concerns and confronts the dependencies and conflicts of interest that undermine the public good is absent in the UK. Although there is a window of opportunity to change the gambling policy system, with the UK Government's launch of a review of the Gambling Act 2005, the adoption of a comprehensive and meaningful public health approach is not guaranteed. Too often, government policy has employed discourses that align more closely with those of the gambling industry than with those of the individuals, families, and communities affected by the harms of gambling. In view of the well described commercial determinants of health and corporate behaviour, an immense effort will be needed to shift the gambling discourse to protect public health. In this Viewpoint, we seek to advance this agenda by identifying elements that need challenging and stimulating debate.

ABSTRACT

BACKGROUND: The HEALing Communities Study (HCS) is testing whether the Communities that Heal (CTH) intervention can decrease opioid overdose deaths through the implementation of evidence-based practices (EBPs) in highly impacted communities. One of the CTH intervention components is a series of communications campaigns to promote the implementation of EBPs, increase demand for naloxone and medications for opioid use disorder (MOUD), and decrease stigma toward people with opioid use disorder and the use of EBPs, especially MOUD. This paper describes the approach to developing and executing these campaigns. METHODS: The HCS communication campaigns are developed and implemented through a collaboration between communication experts, research site staff, and community coalitions using a three-stage process. The Prepare phase identifies priority groups to receive campaign messages, develops content for those messages, and identifies a "call to action" that asks people to engage in a specific behavior. In the Plan phase, campaign resources are produced, and community coalitions develop plans to distribute campaign materials. During the Implement stage, these distribution plans guide delivery of content to priority groups. Fidelity measures assess how community coalitions follow their distribution plan as well as barriers and facilitators to implementation. An evaluation of the communication campaigns is planned. CONCLUSIONS: If successful, the Prepare-Plan-Implement process, and the campaign materials, could be adapted and used by other communities to address the opioid crisis. The campaign evaluation will extend the evidence base for how communication campaigns can be developed and implemented through a community-engaged process to effectively address public health crises.

ABSTRACT

BACKGROUND: Digital or video games are played by millions of adolescents and young adults around the world and are one of the technologies used by youths to access mental health services. Youths with mental health problems strongly endorse the use of technologies, including mobile and online platforms, to receive information, support their treatment journeys (eg, decision-making tools), and facilitate recovery. A growing body of literature explores the advantages of playing digital games for improving attention span and memory, managing emotions, promoting behavior change, and supporting treatment for mental illness (eg, anxiety, depression, or posttraumatic stress disorder). The research field has also focused on the negative impact of video games, describing potential harms related to aggression, addiction, and depression. To promote clarity on this matter, there is a great need for knowledge synthesis offering recommendations on how video games can be safely and effectively adopted and integrated into youth mental health services. OBJECTIVE: The Gaming My Way to Recovery scoping review project assesses existing evidence on the use of digital game interventions within the context of mental health services for youths (aged 11-29 years) using the stepped care model as the conceptual framework. The research question is as follows: For which youth mental health conditions have digital games been used and what broad objectives (eg, prevention, treatment) have they addressed? METHODS: Using the methodology proposed by Arksey and O'Malley, this scoping review will map the available evidence on the use of digital games for youths between 11 and 29 years old with mental health or substance use problems, or both. RESULTS: The review will bring together evidence-based knowledge to assist mental health providers and policymakers in evaluating the potential benefits and risks of these interventions. Following funding of the project in September 2018, we completed the search in November 2018, and carried out data screening and stakeholder engagement activities during preparation of the protocol. We will conduct a knowledge synthesis based on specific disorders, treatment level and modality, type of service, population, settings, ethical practices, and user engagement and offer recommendations concerning the integration of video game technologies and programs, future research and practice, and knowledge dissemination. CONCLUSIONS: Digital game interventions employ unique, experiential, and interactive features that potentially improve skills and facilitate learning among players. Digital games may also provide a new treatment platform for youths with mental health conditions. Assessing current knowledge on video game technology and interventions may potentially improve the range of interventions offered by youth mental health services while supporting prevention, intervention, and treatment.

ABSTRACT

Determining parameters that govern pathogen transmission (such as the force of infection, FOI), and pathogen impacts on morbidity and mortality, is exceptionally challenging for wildlife. Vital parameters can vary, for example across host populations, between sexes and within an individual's lifetime.Feline immunodeficiency virus (FIV) is a lentivirus affecting domestic and wild cat species, forming species-specific viral-host associations. FIV infection is common in populations of puma (Puma concolor), yet uncertainty remains over transmission parameters and the significance of FIV infection for puma mortality. In this study, the age-specific FOI of FIV in pumas was estimated from prevalence data, and the evidence for disease-associated mortality was assessed.We fitted candidate models to FIV prevalence data and adopted a maximum likelihood method to estimate parameter values in each model. The models with the best fit were determined to infer the most likely FOI curves. We applied this strategy for female and male pumas from California, Colorado, and Florida.When splitting the data by sex and area, our FOI modeling revealed no evidence of disease-associated mortality in any population. Both sex and location were found to influence the FOI, which was generally higher for male pumas than for females. For female pumas at all sites, and male pumas from California and Colorado, the FOI did not vary with puma age, implying FIV transmission can happen throughout life; this result supports the idea that transmission can occur from mothers to cubs and also throughout adult life. For Florida males, the FOI was a decreasing function of puma age, indicating an increased risk of infection in the early years, and a decreased risk at older ages.This research provides critical insight into pathogen transmission and impact in a secretive and solitary carnivore. Our findings shed light on the debate on whether FIV causes mortality in wild felids like puma, and our approach may be adopted for other diseases and species. The methodology we present can be used for identifying likely transmission routes of a pathogen and also estimating any disease-associated mortality, both of which can be difficult to establish for wildlife diseases in particular.

ABSTRACT

BACKGROUND: Women younger than 45 years old have lower rates of breast cancer, but higher risk of recurrence and mortality after a cancer diagnosis. African American women are at risk for early onset and increased mortality; Ashkenazi Jewish women are at risk for genetic mutations leading to breast and ovarian cancer. Although younger women are encouraged to talk to doctors about their family history, little is known about these discussions. MATERIALS AND METHODS: In 2015, 167 women aged 18-44 years participated in 20 focus groups segmented by geographic location, age, race/ethnicity, and family history of breast and ovarian cancer. Transcript data were analyzed using NVivo 10 software. RESULTS: Although the majority of women talked to their doctor about breast and ovarian cancer, these conversations were brief and unsatisfying due to a lack of detail. Topics included family history, breast cancer screening, and breast self-examination. Some women with and without family history reported that healthcare providers offered screening and early detection advice based on their inquiries. However, few women took action or changed lifestyle behaviors with the intent to reduce risk as a result of the conversations. CONCLUSIONS: Conversations with young women revealed missed opportunities to: enhance patient-provider communication and increase knowledge about breast cancer screening and surveillance for higher risk patients. Physicians, allied health professionals, and the public health community can better assist women in getting accurate and timely information about breast and ovarian cancer, understanding their family history to determine risk, and increasing healthy behaviors.

ABSTRACT

OBJECTIVES: To report our success and complication rates with emergency department (ED) technician-performed ultrasound (US)-guided peripheral intravenous (IV) catheter placement and to compare our results to similar studies in the literature. METHODS: We conducted a retrospective review of a prospective database of patients who underwent US-guided peripheral IV catheter placement attempts for clinical care in the ED. All patients meeting difficult IV access criteria who had a US-guided peripheral IV catheter placement attempted by a trained ED technician were included. Average attempts per success and overall success rates were compared to similar published studies. RESULTS: There were 830 participants, with an overall success rate of ED technician- performed US-guided peripheral IV catheter placement of 97.5%. Clinicians categorized 82.6% of participants as having difficult IV access and reported that in 46.5%, a central venous catheter would have been necessary if the US-guided peripheral IV catheter failed. Of successful catheter attempts, 86.8% were placed on the first attempt; 11.6% were placed on the second attempt; and 1.6% were placed on the third attempt. For this study, the average number of attempts per success was 1.15 (95% confidence interval, 1.12-1.18), which was lower than in 6 other published studies, ranging from 1.27 to 1.70. The overall success rate of our ED technician-performed attempts was 0.970 (95% confidence interval, 0.956-0.983), which was higher than that reported in previous ED technician studies (0.79-0.80), and closer to that reported for physicians or nurses (0.87-0.97). The arterial puncture complication rate was 0.8%, which was also lower than in other published studies (1.25%-9.80%). CONCLUSIONS: With brief but comprehensive training, ED technicians can successfully obtain US-guided peripheral IV catheter access in patients with difficult IV access.

ABSTRACT

BACKGROUND: Severe sepsis and septic shock mortality has improved; however, rates of persistent (28-90 days) and long-term (>90 day) organ dysfunction in sepsis survivors are unknown. METHODS: Secondary analysis of a prospective cohort of adult emergency department patients with severe sepsis. RESULTS: Of 110 sepsis admissions, we obtained follow-up on 51 of 78 survivors of whom 41% (21 of 51) had persistent organ dysfunction: pulmonary, 18% (9 of 51); renal, 22% (11 of 51); coagulopathy, 10% (5 of 51); cardiovascular, 6% (3 of 51); hepatic, 2% (1 of 51); and neurologic, 3% (3 of 51). We obtained follow-up on 40 of 73 survivors at more than 90 days of whom 38% (15 of 40) had long-term organ dysfunction: pulmonary, 13% (5 of 40); renal, 18% (7 of 40); coagulopathy, 3% (1 of 40); cardiovascular, 5% (2 of 40); hepatic, 0%; and neurologic, 5% (2 of 40). Readmission rate within 90 days was 32% (25 of 78), and recurrent sepsis was the cause of readmission in 52% (13 of 25). Baseline SOFA scores from the index sepsis admission were compared using Wilcoxon rank-sum test and were significantly different in participants with organ dysfunction versus those without organ dysfunction at less than 90 days (z, -2.51; p = 0.01). CONCLUSION: Readmission with recurrent sepsis and organ dysfunction occurs frequently in sepsis survivors. Baseline SOFA score may be predictive of sepsis recidivism and persistent or recurrent organ dysfunction. LEVEL OF EVIDENCE: Prognostic/epidemiologic study, level IV.

ABSTRACT

BACKGROUND: Acute complex C2 vertebral body fracture specifically does not involve the odontoid process or C2 pars interarticularis. External stabilization can be effective but may prolong healing and increase morbidity. Many traditional surgical techniques can achieve internal stabilization at the expense of normal cervical motion. We describe direct surgical C2 pedicle screw fixation as an option for managing acute complex C2 vertebral body fracture. CASE DESCRIPTION: Three patients were treated with direct pedicle screw fixation of acute traumatic complex C2 vertebral body fractures. All fractures were coronally oriented Benzel type 1. None of the patients sustained neurological injury. Stereotactic navigation with intraoperative computed tomography scanning was used for each procedure. Surgery provided immediate internal orthosis and stability, as judged by intraoperative dynamic fluoroscopy. Rigid cervical collar bracing was used for 1 month after surgery when the patients were out of bed. Initial radiographs showed acceptable screw placement and fracture alignment. Dynamic radiographs at 3 months showed structural stability at the fracture site and adjacent levels, and complete bony union was confirmed with late computed tomography scanning (>1 year) in each case. Each patient reported resolution of trauma-related and postsurgical pain at 30-day follow-up. Postoperative Neck Disability Index questionnaires for each patient suggested no significant disability at 1 year. CONCLUSIONS: Direct pedicle screw fixation of acute complex C2 vertebral body fracture appeared to be safe and effective in our 3 patients. It may provide a more-efficient and less-morbid treatment than halo brace or cervical collar immobilization in some patients.

ABSTRACT

The Centers for Disease Control and Prevention's Division of Cancer Prevention and Control, in partnership with Oak Ridge Associated Universities, designed an online social marketing strategy tool, MessageWorks, to help health communicators effectively formulate messages aimed at changing health behaviors and evaluate message tactics and audience characteristics. MessageWorks is based on the advisor for risk communication model that identifies 10 variables that can be used to predict target audience intentions to comply with health recommendations. This article discusses the value of the MessageWorks tool to health communicators and to the field of social marketing by (1) describing the scientific evidence supporting use of MessageWorks to improve health communication practice and (2) summarizing how to use MessageWorks and interpret the results it produces.

ABSTRACT

BACKGROUND: Heart failure (HF) is a major healthcare problem contributing significantly to hospital admission stays and National Health Service (NHS) spending. Reducing length of hospital stay (LoS) in HF is paramount in reducing this burden and is influenced by factors relating to the condition, sociodemographics and comorbidities. Psychiatric comorbidities are being increasingly identified amongst HF patients but their impact on LoS has not been studied in the UK. METHODS: We investigated the impact of psychiatric comorbidities on LoS amongst 31,760 HF patients admitted to hospitals in North England between 1st January 2000 and 31st March 2013 from the ACALM (Algorithm for Comorbidities, Associations, Length of stay and Mortality) study. The ACALM protocol uses ICD-10 and OPCS-4 coding to trace HF patients, psychiatric comorbidities and demographics including LoS. RESULTS: Amongst 31,760 HF patients mean LoS in the absence of psychiatric comorbidities was 11.2days. The presence of a psychiatric comorbidity increased LoS by 3.3days. Logistic regression accounting for age, gender and ethnicity showed that LoS was significantly longer in patients suffering from depression (3.4days, p<0.001), bipolar disorder (8.8days, p<0.001) and all types of dementia (4.2days, p<0.001). CONCLUSIONS: Our results demonstrate that psychiatric comorbidities have a significant and clinically important impact on LoS in HF patients in the UK. Clinicians should be actively aware of psychiatric conditions amongst HF patients and manage them to reduce LoS and ultimately the risk for patients and financial burden for the NHS.

ABSTRACT

Infectious disease transmission often depends on the contact structure of host populations. Although it is often challenging to capture the contact structure in wild animals, new technology has enabled biologists to obtain detailed temporal information on wildlife social contacts. In this study, we investigated the effects of raccoon contact patterns on rabies spread using network modelling. Raccoons (Procyon lotor) play an important role in the maintenance of rabies in the United States. It is crucial to understand how contact patterns influence the spread of rabies in raccoon populations in order to design effective control measures and to prevent transmission to human populations and other animals. We constructed a dynamic system of contact networks based on empirical data from proximity logging collars on a wild suburban raccoon population and then simulated rabies spread across these networks. Our contact networks incorporated the number and duration of raccoon interactions. We included differences in contacts according to sex and season, and both short-term acquaintances and long-term associations. Raccoons may display different behaviours when infectious, including aggression (furious behaviour) and impaired mobility (dumb behaviour); the network model was used to assess the impact of potential behavioural changes in rabid raccoons. We also tested the effectiveness of different vaccination coverage levels. Our results demonstrate that when rabies enters a suburban raccoon population, the likelihood of a disease outbreak affecting the majority of the population is high. Both the magnitude of rabies outbreaks and the speed of rabies spread depend strongly on the time of year that rabies is introduced into the population. When there is a combination of dumb and furious behaviours in the rabid raccoon population, there are similar outbreak sizes and speed of spread to when there are no behavioural changes due to rabies infection. By incorporating detailed data describing the variation in raccoon contact rates into a network modelling approach, we were able to show that suburban raccoon populations are highly susceptible to rabies outbreaks, that the risk of large outbreaks varies seasonally and that current vaccination target levels may be inadequate to prevent the spread of rabies within these populations. Our findings provide new insights into rabies dynamics in raccoon populations and have important implications for disease control.

ABSTRACT

Language asymmetry between patients with limited English proficiency and health care providers increases the complexity of patient-provider communication. In this research, we used conversation analysis to examine the content and processes of five triadic clinical communication encounters between Spanish-speaking adult patients, English-speaking nurse practitioners, and clinic-based interpreters. Data collection included audio-recordings of the triadic clinical encounters and self-administered post-encounter surveys of the nurse practitioners and interpreters. Our findings revealed communication trouble spots that, when directly addressed by the interactants, facilitated processes of negotiating relationships, and coming to a mutual understanding. Exemplars labeled Making Assumptions; Colloquialisms as Signaling Potential for Trouble; Repairing a Mis-Statement; and Turn-Taking, Silences, and Laughter illustrated how the parties identified and navigated such trouble spots. The final exemplar, Attaining Intersubjectivity, represented a successful multi-lingual triadic communication. While the role of the interpreter often is seen as a conduit of information from one language to another, in practice they also enacted roles of communication collaborators and coconstructors. Future interdisciplinary research can include closer examination of occurrences of communication trouble spots and further exploration of how interpretermediated communication is conceptualized and problematized in diverse clinical settings, to promote language interpretation policies and practices that contribute to reducing health disparities among limited-English-proficient populations.

ABSTRACT

PURPOSE: To estimate the maximum tolerated dose (MTD) for continuous oral administration of the γ-secretase inhibitor PF-03084014, determine the recommended phase II dose (RP2D), and evaluate safety and preliminary activity in patients with advanced solid tumors. EXPERIMENTAL DESIGN: This open-label, phase I study consisted of a dose-finding portion based on a 3+3 design, followed by an expansion cohort. PF-03084014 was administered orally, twice daily (BID) for 21 continuous days. Tested doses ranged from 20 to 330 mg BID. In the expansion cohort, patients were to receive the estimated MTD or a lower dose of PF-03084014. RESULTS: A total of 64 patients received treatment. The MTD was estimated to be 220 mg BID. The RP2D was determined to be 150 mg BID, based on the better safety profile versus the 220-mg BID dose, given comparable NOTCH-related target inhibition. The most common treatment-related adverse events were diarrhea, nausea, fatigue, hypophosphatemia, vomiting, rash, and decreased appetite, which were generally mild to moderate in severity. One patient with advanced thyroid cancer had a complete response, and five of seven response-evaluable patients with desmoid tumor achieved a partial response (71.4% objective response rate). Tumor responses were mostly durable, ranging from 1.74+ to 24+ months. PF-03084014 demonstrated a generally dose-dependent pharmacokinetic profile at doses ranging from 20 to 330 mg BID. Consistent downmodulation of NOTCH-related HES4 gene expression was observed in peripheral blood from all evaluable patients. CONCLUSION: Further development of PF-03084014 for the treatment of patients with advanced solid tumors is warranted and currently under evaluation.

ABSTRACT

Although multiracial individuals are the fastest growing population in the United States, research on the identity development of multiracial adolescents remains scant. This study explores the relationship between ethnic identity, its components (affirmation, exploration), and mental health outcomes (anxiety, depressive symptoms) within the contexts of schools for multiracial adolescents. The participants were multiracial and monoracial minority and majority high school students (n = 4,766; 54.6% female). Among the participants, 88.1% were Caucasian, 7.4% were African American, and 4.5% were multiracial. The research questions examined the relationship between ethnic identity exploration and affirmation on mental health outcomes and explored the role school context plays in this relationship. The findings suggested that multiracial youth experience more exploration and less affirmation than African Americans, but more than Caucasians. In addition, multiracial youth were found to have higher levels of mental health issues than their monoracial minority and majority peers. Specifically, multiracial youth had higher levels of depressive symptoms than their African American and Caucasian counterparts. Multiracial and Caucasian youth had similar levels of anxiety but these levels were significantly higher than African Americans. School diversity did not influence mental health outcomes for multiracial youth. These findings provide insight into the experiences of multiracial youth and underscore the importance of further investigating factors that contribute to their mental health outcomes.
