A rare partnership: patient community and industry collaboration to shape the impact of real-world evidence on the rare disease ecosystem

People with rare lysosomal storage diseases face challenges in their care that arise from disease complexity and heterogeneity, compounded by many healthcare professionals being unfamiliar with these diseases. These challenges can result in long diagnostic journeys and inadequate care. Over 30 years ago, the Rare Disease Registries for Gaucher, Fabry, Mucopolysaccharidosis type I and Pompe diseases were established to address knowledge gaps in disease natural history, clinical manifestations of disease and treatment outcomes. Evidence generated from the real-world data collected in these registries supports multiple stakeholders, including patients, healthcare providers, drug developers, researchers and regulators. To maximise the impact of real-world evidence from these registries, engagement and collaboration with the patient communities is essential. To this end, the Rare Disease Registries Patient Council was established in 2019 as a partnership between the Rare Disease Registries and global and local patient advocacy groups to share perspectives on how registry data are used and disseminated. The Patient Council has resulted in a number of patient initiatives including patient representation at Rare Disease Registries advisory boards; development of plain language summaries of registry publications to increase availability of real-world evidence to patient communities; and implementation of digital innovations such as electronic patient-reported outcomes, and patient-facing registry reports and electronic consent (in development), all to enhance patient engagement. The Patient Council is building on the foundations of industry-patient advocacy group collaboration to fully integrate patient communities in decision-making and co-create solutions for the rare disease community.

Rare lysosomal disease registries: lessons learned over three decades of real-world evidence

Lysosomal storage disorders (LSD) are rare diseases, caused by inherited deficiencies of lysosomal enzymes/transporters, that affect 1 in 7000 to 1 in 8000 newborns. Individuals with LSDs face long diagnostic journeys during which debilitating and life-threatening events can occur. Clinical trials and classical descriptions of LSDs typically focus on common manifestations, which are not representative of the vast phenotypic heterogeneity encountered in real-world experience. Additionally, recognizing that there was a limited understanding of the natural history, disease progression, and real-world clinical outcomes of rare LSDs, a collaborative partnership was pioneered 30 years ago to address these gaps. The Rare Disease Registries (RDR) (for Gaucher, Fabry, Mucopolysaccharidosis type I, and Pompe), represent the largest observational database for these LSDs. Over the past thirty years, data from the RDRs have helped to inform scientific understanding and the development of comprehensive monitoring and treatment guidelines by creating a framework for data collection and establishing a standard of care, with an overarching goal to improve the quality of life of affected patients. Here, we highlight the history, process, and impact of the RDRs, and discuss the lessons learned and future directions.

An online Sexual Health and Rehabilitation eClinic (TrueNTH SHAReClinic) for prostate cancer patients: a feasibility study

Purpose

The primary objective was to determine the feasibility of implementing the TrueNTH SHAReClinic as a pan-Canadian sexual health and rehabilitation intervention for patients treated for localized prostate cancer.

Methods

The feasibility study was designed to evaluate the accessibility and acceptability of the intervention. Participants from five institutions across Canada were enrolled to attend one pre-treatment and five follow-up online clinic visits over 1 year following their prostate cancer (PC) treatment.

Results

Sixty-five patients were enrolled in the intervention. Website analytics revealed that 71% completed the intervention in its entirety, including the educational modules, with an additional 10% completing more than half of the intervention. Five thousand eighty-three views of the educational modules were made along with 654 views of the health library items. Over 1500 messages were exchanged between participants and their sexual health coaches. At 12 months, the intervention received an overall average participant rating of 4.1 out of 5 on a single item satisfaction measure.

Conclusion

Results support the TrueNTH SHAReClinic as highly acceptable to participants as defined by intervention adherence and engagement. The TrueNTH SHAReClinic demonstrated promise for being a feasible and potentially resource-efficient approach to effectively improving the sexual well-being of patients after PC treatment.

Effects of the macroalga Asparagopsis taxiformis and oregano leaves on methane emission, rumen fermentation, and lactational performance of dairy cows

Asparagopsis taxiformis (AT) is a source of multiple halogenated compounds and, in a limited number of studies, has been shown to decrease enteric CH₄ emission in vitro and in vivo. Similarly, oregano has been suggested as a potential CH₄ mitigating agent. This study consisted of 2 in vitro and 2 in vivo experiments. Experiment (Exp.) 1 was aimed at establishing the effect of AT on CH₄ emission in vitro. Two experiments (Exp. 2 and 3) with lactating dairy cows were conducted to determine the antimethanogenic effect of AT and oregano (Exp. 3) in vivo. Another experiment (Exp. 4) was designed to investigate stability of bromoform (CHBr₃) in AT over time. In Exp. 3, 20 Holstein cows were used in a replicated 4 × 4 Latin square design with four 28-d periods. Treatments were basal diet (control) or basal diet supplemented with (dry matter basis) 0.25% AT (LowAT), 0.50% AT (HighAT), or 1.77% oregano (Origanum vulgare L.) leaves. Enteric gas emissions were measured using the GreenFeed system (C-Lock Inc., Rapid City, SD), and rumen samples were collected for fermentation analysis using the ororuminal technique. In Exp.1 (in vitro), relative to the control, AT (at 1% dry matter basis, inclusion rate) decreased CH₄ yield by 98%. In Exp. 3, HighAT decreased average daily CH₄ emission and CH₄ yield by 65% and 55%, respectively, in experimental periods 1 and 2, but had no effect in periods 3 and 4. The differential response to AT among experimental periods was likely a result of a decrease in CHBr₃ concentration in AT over time, as observed in Exp. 4 (up to 84% decrease in 4 mo of storage). In Exp. 3, H₂ emission was increased by AT and, as expected, the proportion of acetate in the total volatile fatty acids in the rumen was decreased and those of propionate and butyrate were increased by HighAT compared with the control. Compared with the control, HighAT decreased dry matter intake, milk yield, and energy-corrected milk yield in Exp. 3. Milk composition was not affected by treatment, except lactose percentage and yield were decreased by HighAT. Concentrations of iodine and bromide in milk were increased by HighAT compared with the control. Milk CHBr₃ concentration and its organoleptic characteristics were not different between control and HighAT. Oregano had no effect on CH₄ emission or lactational performance of the cows in Exp. 3. Overall, AT included at 0.50% in the ration of dairy cows can have a large mitigation effect on enteric CH₄ emission, but dry matter intake and milk production may also decrease. There was a marked decrease in the CH₄ mitigation potential of AT in the second half of Exp. 3, likely resulting from CHBr₃ decay over time.

Counselled Patients with Stroke Still Experience Sexual and Relational Problems 1–5 Years After Stroke Rehabilitation

To describe sexual functioning/satisfaction and relational satisfaction of patients with stroke who received sexual counselling during their rehabilitation 1–5 years thereafter. All adult patients with stroke admitted to one Dutch Rehabilitation Centre between January 2010 and January 2014 with at least two consultations with a sexologist were invited to participate in this cross-sectional survey study. Patients were asked to complete a questionnaire on sexual functioning, relational satisfaction (Maudsley Marital Questionnaire, 0–80; low–high dissatisfaction), health-related quality of life (HRQoL) short-form12 (SF-12) mental and physical component scale (MCS and PCS; 0–100, low–high HRQoL) and mood Hospital Anxiety Depression Scale (HADS, 0–21 low–high depression/anxiety). Descriptive statistics were used for sexual functioning/satisfaction and relational satisfaction. Spearmans’s correlation analysis (rs) analyzed the relationships between sexual satisfaction, relational satisfaction, PCS, MCS, depression and anxiety. Of 296 eligible patients, 62 (21%) completed the questionnaires. Mean age 55.4 (SD11.0) years, time-since-stroke 3.5 (SD3.6) years, 33 (53%) were male and 18 (29%) were single. Being sexually (very) unsatisfied was reported by 31 (54%) responders, with 63% being male and 44% female. Median MMQ-score relational satisfaction was 12.0 (IQR 4.25–23.25). A moderate correlation was present between sexual and relational satisfaction (rs = 0.35, p = 0.02). In male respondents relational satisfaction was highly correlated with lower levels of anxiety (rs = 0.54, p = 0.01) and depressive symptoms (rs = 0.71, p = 0.00). Patients with stroke who received sexual counselling during their rehabilitation treatment experience high relational satisfaction in the long term after stroke, despite their problems in sexual functioning.

Animal movement drives variation in seed dispersal distance in a plant-animal network

Frugivores play differing roles in shaping dispersal patterns yet seed dispersal distance is rarely quantified across entire communities. We model seed dispersal distance using gut passage times and bird movement for the majority (39 interactions) of known bird-tree interactions on the island of Saipan to highlight differences in seed dispersal distances provided by the five avian frugivores. One bird species was found to be a seed predator rather than a disperser. The remaining four avian species dispersed seeds but differences in seed dispersal distance were largely driven by interspecific variation in bird movement rather than intraspecific variation in gut passage times. The median dispersal distance was at least 56 m for all species-specific combinations, indicating all species play a role in reducing high seed mortality under the parent tree. However, one species-the Micronesian Starling-performed 94% of dispersal events greater than 500 m, suggesting this species could be a key driver of long-distance dispersal services (e.g. linking populations, colonizing new areas). Assessing variation in dispersal patterns across this network highlights key sources of variation in seed dispersal distances and suggests which empirical approaches are sufficient for modelling how seed dispersal mutualisms affect populations and communities.

Identifying Determinants of Intervention Sustainability in Cancer Survivorship Care

Background: Substantial gains could be made in reducing the cancer burden if current scientific evidence was applied in practice. The World Health Organization estimates that, worldwide, one-third of cancer cases could be prevented and another one-third cured if evidence was consistently implemented and sustained in cancer care. However, moving evidence-based interventions into care has proven a significant challenge. Even when interventions are put into practice, they often fail to become integrated into the long-term routines of organizations. This poor sustainability means many patients do not benefit from the best care possible. There is little empirical data on the factors that influence the sustainability of interventions in clinical settings. Aim: To identify the determinants of, and explore the processes that facilitate, sustainability of interventions in cancer care survivorship. Sustainability was defined as the continued use of an intervention and its associated components and/or the continued achievement of the intended benefits after the initial funding or support period. Methods: We first conducted an environmental scan to identify interventions in cancer survivorship care implemented in Canada. This was followed by a literature review to ascertain the evidence base for each intervention and identify those meeting the US National Cancer Institute's criteria for evidence-based interventions. We then recruited key individuals relevant to the evidence-based interventions for semistructured in-depth interviews to explore issues related to their sustainability. Interview data are being analyzed through an inductive grounded theory approach using constant comparative analysis. Results: Twenty-seven individuals participated in the interviews. Preliminary findings reveal five factors that influenced whether, and the extent to which, interventions were sustained in cancer survivorship care. Participants emphasized (1) access to sufficient resources and funding is critical to sustaining interventions after the initial funding period. The ability of a team or organization to (2) evaluate a new intervention and demonstrate its quality and usefulness was often perceived as necessary to obtain continued funding as well as ongoing buy in and support from key stakeholders. In addition, the (3) extent to which the intervention can be adapted, (4) support of senior management, and (5) existence of an on-the-ground champion to continuously promote, adapt, lead, and spread the intervention were perceived as important factors that contribute to an intervention's sustained use. Conclusion: Research into determinants and processes of sustainability is critical to ensure we plan and act in ways that maximize the sustained use of interventions shown to benefit patients and our cancer systems. Issues related to evaluation, adaptability, and ongoing moral and material supports should be considered before, during, and after implementation efforts.

When Environmental Forces Collide

Multiple factors often interact to amplify the effects of severe storms, droughts, and other extreme water-related events.

Epidemiologic Investigation of Highly Pathogenic H5N2 Avian Influenza Among Upper Midwest U.S. Turkey Farms, 2015

In 2015, an outbreak of H5N2 highly pathogenic avian influenza (HPAI) occurred in the United States, severely impacting the turkey industry in the upper midwestern United States. Industry, government, and academic partners worked together to conduct a case-control investigation of the outbreak on turkey farms in the Upper Midwest. Case farms were confirmed to have HPAI-infected flocks, and control farms were farms with noninfected turkey flocks at a similar stage of production. Both case and control farms were affiliated with a large integrated turkey company. A questionnaire administered to farm managers and supervisors assessed farm biosecurity, litter handling, dead bird disposal, farm visitor and worker practices, and presence of wild birds on operations during the 2 wk prior to HPAI confirmation on case premises and the corresponding time frame for control premises. Sixty-three farms, including 37 case farms and 26 control farms were included in the analysis. We identified several factors significantly associated with the odds of H5N2 case farm status and that may have contributed to H5N2 transmission to and from operations. Factors associated with increased risk included close proximity to other turkey operations, soil disruption (e.g., tilling) in a nearby field within 14 days prior to the outbreak, and rendering of dead birds. Observation of wild mammals near turkey barns was associated with reduced risk. When analyses focused on farms identified with H5N2 infection before April 22 (Period 1), associations with H5N2-positive farm status included soil disruption in a nearby field within 14 days prior to the outbreak and a high level of visitor biosecurity. High level of worker biosecurity had a protective effect. During the study period after April 22 (Period 2), factors associated with HPAI-positive farm status included nonasphalt roads leading to the farm and use of a vehicle wash station or spray area. Presence of wild birds near dead bird disposal areas was associated with reduced risk. Study results indicated that the initial introduction and spread of H5N2 virus likely occurred by both environmental and between-farm pathways. Transmission dynamics appeared to change with progression of the outbreak. Despite enhanced biosecurity protocols, H5N2 transmission continued, highlighting the need to review geographic/topologic factors such as farm proximity and potential dust or air transmission associated with soil disruption. It is likely that biosecurity improvements will reduce the extent and speed of spread of future outbreaks, but our results suggest that environmental factors may also play a significant role in farms becoming infected with HPAI.

On the energetics of P–P bond dissociation of sterically strained tetraamino-diphosphanes

Thermochemical data for the homolytic P–P bond fission in tetraaminodiphosphanes (R₂N)₂P–P(NR₂)₂ were determined experimentally and computationally. The results confirm that radical formation is favoured by entropic and structural relaxation effects, and disfavoured by dispersion forces. Unlike aminophosphenium cations, the radicals display no strong preference for a planar (R₂N)₂P unit.

An anionic phosphenium complex as an ambident nucleophile

Treatment of an N-heterocyclic chlorophosphine with Collman's reagent or K[HFe(CO)₄]/NaH gave a unique anionic phosphenium complex which behaves as an ambident nucleophile.

Does simulation booster impact retention of resuscitation procedural skills and teamwork?

OBJECTIVE

The Neonatal Resuscitation Program (NRP) has transitioned to a simulation-based format. We hypothesized that immersive simulation differentially impacts similar trainee populations' resuscitation knowledge, procedural skill and teamwork behavior.

STUDY DESIGN

Residents from NICU and non-NICU programs were randomized to either control or a booster simulation 7 to 10 months after NRP. Procedural skill and teamwork behavior instruments were validated. Individual resident's resuscitation performance was assessed at 15 to 18 months. Three reviewers rated videos.

RESULT

Fifty residents were assessed. Inter-rater reliability was good for procedural skills (0.78) and team behavior (0.74) instruments. The intervention group demonstrated better procedural skills (71.6 versus 64.4) and teamwork behaviors (18.8 versus 16.2). The NICU program demonstrated better teamwork behaviors (18.6 versus 15.5) compared with non-NICU program.

CONCLUSION

A simulation-enhanced booster session 9 months after NRP differentiates procedural skill and teamwork behavior at 15 months. Deliberate practice with simulation enhances teamwork behaviors additively with residents' clinical resuscitation exposure.
