The article analyzes how tourism businesses can be activated for sustainability by destination management organizations and how a destination sustainability program can be used to promote sustainable development. Based on an applied research project in the canton of Lucerne in Switzerland, different approaches to mobilizing and activating tourism companies for sustainability are analyzed and successful strategies are identified. Experience shows that regular communication via various channels and the involvement of tourism partners are key. Direct contact between the representatives of the destinations or associations and the tourism companies is the most promising way of mobilizing them, although this also involves a great deal of effort. While intrinsically motivated businesses usually hardly need any external incentives, a considerable proportion of businesses only become active when either concrete financial incentives are promised, or they are forced to do so by regulatory requirements. The experience gained from the implementation of various mobilization strategies and their analysis enabled the authors to develop and put up for discussion a typology of motives and associated mobilization strategies.

Very-high-energy electrons, coupled with ultra-high dose rates, are being explored for their potential use in radiotherapy to treat deep-seated tumours. The dose per pulse needed to achieve ultra-high dose rates far exceeds the limit of current medical linear accelerator capabilities. A high dose per pulse has been observed as the limiting factor for many existing dosimeters, resulting in saturation at doses far below what is required. The MOSkin, an existing clinical quality assurance dosimeter, has previously been demonstrated as dose rate independent but has not been subjected to a high dose per pulse. Within this study, the MOSkins dose-per-pulse response was tested for linearity, with a dose per pulse as high as 23 Gy within 200 ns at the ANSTO Australian Synchrotron’s Pulsed Energetic Electrons for Research facility. While using EBT-XD film as a reference dosimeter, a dose rate dependence of the EBT-XD was discovered. Once confirmed and a correction factor established, EBT-XD was used as an independent reference measurement. This work presents confirmation of the MOSkin suitability for ultra-high dose-rate environments with an electron energy of 100 MeV, and a theoretical discussion of its dose-rate and dose-per-pulse independence; the MOSkin is the only detector suitable for both clinical quality assurance, and ultra-high dose-rate measurements in its standard, unmodified form.

Whether pattern or amount of daily activity determines neuromuscular properties is the focus of this review. The fast-to-slow conversion of many properties of fast-twitch muscles, by stimulating their nerves electrically with the continuous low-frequency pattern typical of slow motoneurons, argued that muscle properties are determined by their pattern of activity. However, the composition of the motor units (MUs) in almost all muscles is heterogeneous, with the MUs grouped into slow, fast-fatigue-resistant and fast-fatigable types that match corresponding histochemical fiber types. Nonetheless, their contractile forces lie on a continuum, with MUs recruited into activity in order of their size. This ‘size principle’ of MU organization and function applies in normally innervated and reinnervated muscles and, importantly, begs the question of whether it is the amount rather than the pattern of the MU activation that determines their properties. Experimental evidence that uniform daily amounts of ~<0.5, 5%, and 50% ES, converted motoneuron, nerve, and muscle properties to one physiological and histochemical type, argued in favor of the amount of activity determining MU properties. Yet, that the properties were not confined to the expected narrow range argued that factors other than the pattern and/or amount of neuromuscular activity must be considered. These include the progressive increase in the synaptic inputs onto motoneurons. The range of the effects of endurance and intermittent exercise programs on healthy subjects and those suffering nerve injuries and disease is also consistent with the argument that factors other than pattern or amount of neuromuscular activity should be investigated.

Background: Pneumococcal vaccination rates in the United States (US) remain suboptimal, especially for adults aged 19 to 64 with high-risk medical conditions. Community-pharmacy-based immunization services increase vaccine access, particularly in rural areas. This study describes the provision of pneumococcal immunization services, assesses the processes used to identify and confirm patient eligibility, and determines barriers to immunization services in rural community pharmacies. Methods: A cross-sectional survey was emailed to members of the Rural Research Alliance of Community Pharmacies, located in the southeastern US. The survey assessed which pneumococcal vaccines were offered, age groups, prescription requirements, and how patient eligibility was determined. In addition, participants were asked to rate a series of patient-related and organizational barriers to pneumococcal vaccination. Results: Ninety-four pharmacies completed the survey, with most (96.8%) offering pneumococcal vaccines, most commonly PCV20 (95.6%). Most pharmacies vaccinated patients upon request (98.9%) or when patients presented with a prescription (82.4%), but few proactively contacted patients to schedule the vaccination (17.6%). Pharmacists most often administered pneumococcal vaccines to patients aged 65 and older and used patient age and immunization information systems to identify eligible patients. The most common patient-related barrier was the patient’s belief that they do not need the vaccine. The most common organizational barriers were inadequate reimbursements for vaccine administration and vaccine products. Conclusions: Pneumococcal vaccinations are commonly offered in rural community pharmacies, which play an important role in immunization access. With recent guideline changes to the age-based recommendation, there is an opportunity to optimize strategies to increase vaccine uptake. Full article

Background/Objectives: Frailty is a key determinant of outcomes in older adults with heart failure (HF). The free triiodothyronine/free thyroxine (FT₃/FT₄) ratio has emerged as a promising frailty biomarker that reflects metabolic and systemic resilience. This study investigates its association with frailty, nutrition, muscle strength, inflammation, and one-year mortality in very old patients with HF. Methods: In this longitudinal, single-center study, we enrolled 193 older outpatients (mean age, 86.5 ± 6.1 years; 56% women) recently discharged after acute HF. All patients underwent physical examination, blood testing, and comprehensive geriatric assessment, including handgrip strength (HGS). Participants were stratified by FT₃/FT₄ ratio (<1.7 vs. ≥1.7). Associations with the Clinical Frailty Scale (CFS) were examined using multivariable linear regression. Spearman’s correlations assessed relationships with inflammatory and nutritional biomarkers. Cox regression evaluated the association with all-cause mortality. Results: Patients with a low FT₃/FT₄ ratio (31.1%) exhibited greater frailty (CFS: median [IQR], 6 [2] vs. 4 [3]; p = 0.020), poorer nutritional status (Mini Nutritional Assessment: 10 [4] vs. 12 [3]; p = 0.008), and lower HGS (mean ± SD, 16.8 ± 3.7 kg vs. 20.3 ± 4.8 kg; p = 0.002). An inverse association was identified between the FT₃/FT₄ ratio and frailty (adjusted β = −0.09; p = 0.019). Individuals with low FT₃/FT₄ also showed elevated inflammatory markers and had more than double the one-year mortality rate compared to those with higher ratios [HR 2.32 (95% CI, 1.24–4.34; p = 0.007)]. Conclusions: In very old adults recently hospitalized for HF, a lower FT₃/FT₄ ratio was associated with frailty, malnutrition, inflammation, and increased mortality, supporting its potential role as a marker of biological vulnerability.

Background/Objective: We sought to address ongoing gaps in understanding the relationship between first-week percent maximal weight loss (MWL) and average first-week total fluid intake (TFI), enteral intake, and parenteral intake among premature newborns with adverse in-hospital outcomes born in low- and middle-income countries (LMICs). Methods: We evaluated newborns born <34 weeks gestation or <1500 g who survived at least 7 days at the St. Paul’s Hospital Millennium Medical College (SPHMMC) neonatal intensive care unit in Ethiopia. We performed univariate and multivariate regression models analyzing the first-week MWL, average TFI, parenteral, and enteral intake and their relationships with adverse in-hospital outcomes. Results: Among N = 490 moderately and very preterm newborns, multivariate regression models demonstrated that >13% MWL was associated with significantly increased odds of suspected necrotizing enterocolitis (NEC), culture-positive sepsis, retinopathy of prematurity (ROP), and a longer length of stay (LOS). An average enteral intake of >60 mL/kg/day was significantly associated with reduced odds of all-cause mortality, suspected NEC, culture-positive sepsis, ROP, and a shorter LOS, whereas an average parenteral intake of >60 mL/kg/day was associated with increased odds of in-hospital mortality, culture-positive sepsis, ROP, and a longer LOS. Conclusions: In moderately and very preterm neonates in an LMIC setting, >13% MWL is associated with adverse health outcomes. Increasing the average parenteral intake over the first week after birth among moderately and very preterm neonates is significantly associated with adverse in-hospital outcomes whereas increasing the average enteral intake is associated with improved outcomes.

We conducted a diary study to examine how narcissism influences reactions to daily perceived partner phubbing (N = 196). We examined relationships between two facets of narcissism (rivalry and admiration) and personal and relational well-being, reactions to phubbing, reports of retaliation, and motives for retaliation. On average, participants higher in rivalry reported lower self-esteem and higher depressed and anxious mood, whilst participants higher in admiration reported greater relationship satisfaction, higher self-esteem, lower depressed and anxious mood, and lower levels of anger/frustration. These patterns held regardless of whether they were phubbed or not. In response to partner phubbing, participants higher in rivalry reported, on average, greater curiosity, resentment, conflict, and retaliation. On days when participants reported higher phubbing, those with higher rivalry reported greater curiosity, while those higher in admiration reported greater conflict. When retaliating to phubbing, those higher in rivalry did so, on average, to get back at their partner and to seek support and approval from others, whereas those higher in admiration were less likely to report boredom as a reason for retaliating. Our findings contribute to the sparse literature on narcissism and phubbing by showing how narcissists respond to being phubbed. We discuss how phubbing may exacerbate their relational difficulties.

Background: Eosinophilic esophagitis is a chronic immune-mediated disease with increasing prevalence. In pediatric populations, it often coexists with IgE-mediated food sensitization. This dual diagnosis presents unique therapeutic challenges, including on the one hand both temporary and lifelong dietary restrictions, and on the other hand, therapeutic interventions with a potential impact on quality of life (QoL). Objectives: This study prospectively evaluated the prevalence of IgE-mediated food sensitization and allergy in children with EoE attending a tertiary center in Flanders, Belgium. Additionally, it prospectively documented dietary habits and restrictions in these children, with or without concomitant IgE-mediated food allergies, and assessed the impact of dietary management on quality of life compared to pharmacological treatment. Methods: We consecutively followed 30 children with biopsy-confirmed pediatric EoE (PedEoE) attending a tertiary referral center for at least 12 months. Patient demographics, allergy testing, dietary history, and treatment modalities were recorded. Symptom score and PedEoE QoL were assessed using validated Pediatric Eosinophilic Esophagitis Symptom Score (PEESS 2.0) and Pediatric Quality of Life Inventory (PedsQL 3.0) questionnaires. Statistical analysis was performed using the Mann–Whitney U test and Kruskal–Wallis test with Dunn’s test as a post hoc test. Results: Among 30 children with EoE (60% male, median age 8 years), 60 PedEoE QoL (PedsQL) and 39 symptom (PEESS) questionnaires were collected at one or more time points over a median follow-up of 14.5 months. IgE sensitization to common dietary triggers was observed in multiple patients, with varying clinical reactivity. Symptom scores tended to be higher in children without histological remission, though differences were not statistically significant (median PEESS 23.75 vs. 17.50, p = 0.1934). Grouped by degree of dietary restriction, QoL scores showed significant differences (child p = 0.0102; parent p = 0.0203), with children in the 1–2 food elimination group reporting better QoL compared to the 0 food elimination and >6 food elimination groups. No clear statistically significant differences were observed between the 1–2 food elimination group and the 3–4 or 5–6 food elimination groups. Conclusions: IgE sensitization is prevalent among pediatric EoE patients and has significant clinical implications for disease management. Treatment choice can influence not only disease control but also the QoL of both patients and their families. Full article

This case report presents the clinical evaluation of an 11-year-old boy with a unilateral polypoid nasal mass causing nasal obstruction, facial asymmetry, and intermittent epistaxis. His clinical picture raised concerns of a juvenile nasopharyngeal angiofibroma; however, further imaging and histopathological evaluation ultimately confirmed the diagnosis of allergic fungal rhinosinusitis (AFRS). Although this patient was younger in age than those traditionally associated with AFRS, classical features present on both computed tomography (CT) and magnetic resonance imaging (MRI) aided in his diagnosis and management. This case underscores the importance of a comprehensive diagnostic approach when evaluating unilateral sinonasal masses in paediatric patients, specifically in atypical presentations where the diagnosis of AFRS may not initially be considered. It highlights the critical role of imaging as a diagnostic tool, specifically CT and MRI, which were pivotal in the work-up and management of this case. Additionally, the need for caution during biopsies of sinonasal masses in children is emphasised, as there is potential for catastrophic bleeding in vascularised masses such as juvenile nasopharyngeal angiofibroma. This case demonstrates that AFRS can occur in younger children, highlighting the need to include this in the differential diagnosis, even in patients outside of the traditionally described age group.

Background/Objectives: Financial distress from the direct and indirect costs of cancer treatment is a critical issue for many patients with breast cancer, particularly those from underserved populations who may be more vulnerable to financial hardship and its negative impacts on quality of life and clinical outcomes (i.e., financial toxicity). Few investigations, however, focus on protective factors that safeguard against financial toxicity. This study explores how social support might reduce financial toxicity among patients with breast cancer who are at high risk for financial hardship. Methods: We analyzed interviews with 41 adult women treated for stage I-IV breast cancer that had been conducted between December 2021 and March 2022. Our study specifically sampled women considered to be at elevated risk for financial toxicity: young adults aged 18–40 years old, Black women, women with lower incomes, and those residing in rural communities. We used deductive and inductive coding to identify themes related to social support. Results: Interviewees reported receiving support from family, friends, and their communities during their treatments. They noted how this social support helped with direct and indirect costs, encouraged emotional wellbeing, and safeguarded against economizing behaviors that offset spending (e.g., financial tradeoffs that jeopardize their treatment plan). Conclusions: Patients with breast cancer from groups vulnerable to financial toxicity often rely on the support of family, friends, and their communities to help buffer financial distress from the costs of treatment. These data highlight social support as an area for future studies exploring strategies to mitigate financial toxicity. Full article

Background/Objectives: Head and neck lymphedema (HNL) is a common complication after head and neck cancer (HNC) treatment. Reliable and feasible assessment methods are essential for monitoring and management. This study aimed to evaluate the reliability and clinical feasibility of three methods for assessing external HNL in HNC patients: local tissue water (%) using the MoistureMeterD Compact (MMDC), neck circumference using a tape measure, and dermal thickness using B-mode ultrasound. Methods: Thirty-three HNC patients with potential HNL were included. Measurements were performed on the same day, twice by the same rater and once by a different rater. Intraclass correlation coefficients (ICC^2,1), (relative) standard error of measurement ((%)SEM), smallest real difference (SRD), systematic differences across measurement occasions, and Bland–Altman plots with 95% limits of agreement were analyzed. Time efficiency and clinical limitations were assessed. As an exploratory analysis, Spearman correlations among methods were examined. Results: All methods demonstrated moderate to very strong reliability (ICCs^2,1 0.781–0.994), except dermal thickness (ICCs^2,1 0.136–0.354). Differences between raters and within one rater were not clinically meaningful. Neck circumference showed the highest reliability (ICCs^2,1 0.958–0.994) and was the fastest to perform with the fewest limitations. The methods showed weak correlations with each other. Conclusions: Neck circumference was the most reliable and time-efficient method assessing HNL in clinical practice but is limited to the neck region. For the head, local tissue water assessment seems the most reliable and feasible. The methods assess different aspects of HNL. Further research should confirm how these methods can complement each another. Full article

Background/Objectives: Understanding virulence determinants can inform safer and more efficacious live attenuated vaccine design. However, applying this knowledge across related viruses does not always result in conserved phenotypes from similar mutants. Methods: Using Usutu virus (USUV), an emerging orthoflavivirus spreading through Europe, we assessed whether the attenuating effect of the mutations described for related orthoflaviviruses is conserved. Candidate attenuating mutations were selected based on previous studies in other orthoflaviviruses and incorporated into USUV. Results: Nine variants, with mutations in the USUV envelope, non-structural (NS) proteins NS1, NS2A, or NS4B were stable and selected for further characterisation. The variants with an attenuating phenotype in cell culture were then compared to the wild-type virus in an Ifnar^−/− mouse model. Mutations of the envelope glycosylation sites and glycosaminoglycan binding sites, which were recognised as more-conserved mechanisms of orthoflavivirus attenuation, were attenuating in USUV as well. However, not all the mutations explored in the USUV non-structural proteins exhibited an attenuated phenotype. Instead, the attenuation was either less pronounced, or there was no change in phenotype relative to the wild-type virus at all. Conclusions: In addition to improving our understanding of USUV virulence determinants, these results add to a growing body of literature highlighting the most promising mechanisms to target for the design of safe live attenuated vaccines against emerging orthoflaviviruses.

Technological advances continually reduce the effort to digitally transform health-related activities such as rehabilitation and training. Exemplary systems use tracking and vital sign monitoring to assess physical condition and training progress. This paper presents a system for body stability training and coordination evaluation, using cost-efficient tracking and monitoring solutions. It implements the use case of app-guided back posture tracking on the ICAROS Pro training device via SteamVR Tracking 2.0, with pulse and respiration rate monitoring via Zephyr BioHarness 3.0. A longitudinal study on training effects with 20 subjects was conducted, involving a representative procedure created with a sports manager. Posture errors served as the main progress indicator, and pulse and respiration rates as co-indicators. Outcomes suggest the system’s capabilities to foster comprehension of effects and steering of exercises. Further, a secondary study presents a self-developed VR-based exergame demo for future system expansion. The Empatica EmbracePlus smartwatch was used as an alternative for vital sign acquisition. The user experiences of five subjects gathered via a survey highlight its motivating and entertaining character. For both the main and secondary studies, a thorough discussion elaborates on potentials and current limitations. The developed training system can serve as template and be adjusted for further use cases, and the exergame’s reception revealed prospective extension directions.

Background: Cytoreductive surgery (CRS), in combination with chemotherapy, is the main treatment for advanced-stage ovarian cancer. In vulnerable patients, this extensive surgery has a high complication risk and may lead to clinical decline. There is emerging evidence that prehabilitation could be valuable in optimizing the patient’s condition prior to cytoreductive surgery, as is shown in colorectal surgery. However, there is limited evidence in gynecologic oncology. The objective of this study is to evaluate the feasibility and effects of implementing multimodal prehabilitation before cytoreductive surgery in patients with ovarian cancer. Methods: In two Dutch hospitals, 46 patients with ovarian cancer were included during the study period, of whom 32 participated in a multimodal prehabilitation program before CRS. The programs included at least physiotherapy, dietary advice and intoxication cessation. The timing, extent and content of the programs differed. Feasibility was assessed by eligibility and participation rates and adherence to the physiotherapy program. Effectiveness was measured by differences in functional capacity, postoperative outcomes and tolerance to adjuvant chemotherapy. Results: Eligibility rates in both hospitals were 83% and 89%, and participation rates were 68% and 72%. Adherence to the physiotherapy program was moderate and only satisfactory in 55% and 63% of the patients. All fitness endpoint measurements improved compared to the baseline. No significant differences in postoperative outcomes were found between prehabilitation and control patients. Prehabilitation patients appeared to have better tolerance to adjuvant chemotherapy, with fewer dose reductions (21% vs. 73%, p = 0.017) and dose deferrals (39% vs. 46%, not significant) compared to the control group. Conclusions: The implementation of multimodal prehabilitation before CRS is feasible and effective in patients with ovarian cancer with respectable eligibility and participation rates, along with improved functional capacity, even during neoadjuvant chemotherapy.
