RESUMEN
INTRODUCTION/OBJECTIVES: Optic nerve sheath (ONS) enhancement using magnetic resonance imaging of the orbits was observed in patients with giant cell arteritis (GCA). We previously showed that ONS diameter (ONSD) by bedside ultrasound is increased in patient with active GCA. This study aims to assess whether ONSD decreases with clinical remission in patients with GCA. METHODS: A prospective cohort study was conducted from June 2022 to January 2023. Patients who had an optic nerve ultrasound at GCA diagnosis as part of a previous crosssectional study were eligible. Optic nerve ultrasound was performed by the same investigator at diagnosis and month 3. ONSD (includes the optic nerve and its sheath) and optic nerve diameter (OND) were measured. Descriptive statistics for baseline characteristics and paired sample t-test were performed to assess the mean difference in OND and ONSD between diagnosis and month 3. RESULTS: Nine patients with GCA were included. The median age at disease onset was 79 years (interquartile range (IQR) of 79-82 years), and 7 patients were males. All patients were in clinical remission at month 3 on prednisone (median dose of 15 mg/day, IQR of 10-25 mg). The mean ONSD was lower at month 3 (3.76 mm) compared to baseline (5.98 mm), with a paired mean difference of 2.22 mm (95% CI 1.41-3.03 mm, p < 0.001). As anticipated, OND measurements did not vary between diagnosis and month 3. CONCLUSION: ONSD on ultrasound improves after 3 months of therapy in patients with GCA. A longer prospective study is required to determine if ONSD is useful to assess disease activity in GCA. Key Points ⢠ONS ultrasound can identify patients with active GCA. ⢠The ONSD on ultrasound is dynamic and improved after 3 months of GCA therapy. ⢠ONS ultrasound may be useful to monitor disease activity in GCA.
RESUMEN
The introduction of complementary food plays a fundamental role in dietary behaviours later in life. Little is known about the influences of age on food texture acceptance in young Indian children. Thus, the objective of this cross-sectional study was to describe the relationship between age and food texture experiences in young children aged 4-36 months in India from urban areas using a parental-reported survey. This study relies on a face-to-face parent survey, which was conducted comprising 306 children categorised into 9 age groups. Questions focussed on food texture experience considering 16 textures were analysed. Textures such as dissolvable, sticky, and soupy/liquidy were already accepted by more than half of 4-5-month-old infants. In India, soupy/liquidy is a more common base texture than pureed. Indeed, pureed was found to be introduced to a majority of infants only from 8 to 9 months onwards. Food textures such as rubbery, slippery, and foods with skin were more likely rejected by the youngest children. With increasing age, the refusal probability of food textures decreased. Our survey showed food texture experiences in Indian children aged from 4 to 36 months. It provides useful insights for parents and healthcare professionals by contributing to the understanding of texture acceptance during the transition to complementary foods.
RESUMEN
OBJECTIVE: Optic nerve sheath enhancement on magnetic resonance imaging has been reported in patients with giant cell arteritis (GCA), with or without visual manifestations. Whether similar findings can be documented on ultrasound is unknown. Optic nerve ultrasound is a point-of-care, easy to learn, rapid, and noninvasive technique. This study aims to investigate whether optic nerve sheath diameter (ONSD) measured on ultrasound is useful in the diagnosis of active, new-onset GCA. METHODS: A single-center, diagnostic accuracy study was performed from June to November 2022 on consecutive eligible patients referred for suspected GCA. Optic nerve ultrasound was performed on both eyes. The ONSD (includes the optic nerve and its sheath) and optic nerve diameter (OND) were measured 3 mm behind the ocular globe. The presence or absence of GCA was confirmed clinically 6 months later. Multivariable linear regression, adjusting for age and sex, was used to determine the association between optic nerve ultrasound measures and final GCA diagnosis. RESULTS: Thirty participants were enrolled, including nine participants with a final diagnosis of GCA. Mean ± SD ONSD was 5.98 ± 1.17 mm in patients with GCA and 4.02 ± 0.99 mm in patients without GCA. Mean ONSD was greater by 1.26 mm in patients with GCA (95% confidence interval 0.30-2.21 mm, P = 0.01) compared with those without GCA, adjusting for age and sex. Mean ± SD OND was 2.97 ± 0.46 mm in patients with GCA and 2.47 ± 0.58 mm in patients without GCA. There was no evidence of an association between GCA diagnosis and OND. CONCLUSION: Patients with GCA had a significantly greater ONSD on ultrasound than patients without GCA. Optic nerve ultrasound may represent a novel, rapid, bedside diagnostic test for GCA. A large prospective study is required to confirm these findings and evaluate whether ONSD can be used as a disease activity biomarker in GCA.
RESUMEN
BACKGROUND: Giant cell arteritis (GCA) is the most common systemic vasculitis in adults. Presenting features include new-onset headaches, constitutional symptoms, jaw claudication, polymyalgia rheumatica, and visual symptoms. Arterial inflammation with subsequent stenosis and occlusion may cause tissue ischemia, leading to blindness, strokes, and myocardial infarction. Oral antiplatelet therapy has been hypothesized to reduce GCA-related ischemic events. However, previous studies have demonstrated conflicting results regarding the efficacy of antiplatelet agents in GCA. The objective of this systematic review is to assess the safety and efficacy of antiplatelet therapy for the prevention of these events in adults with giant cell arteritis. METHODS: In this systematic review, we will include randomized controlled trials (RTCs), quasi-randomized trials, non-randomized intervention studies, cohort studies, and case-control studies on patients with new-onset or relapsing GCA. The intervention of interest will be pre-existing use or initiation of an oral antiplatelet medication (aspirin, clopidogrel, prasugrel, or ticagrelor) at GCA onset or relapse. The comparator of interest will be the absence of antiplatelet therapy. Endpoints will be evaluated after 6 and 12 months of follow-up. The primary outcome will be GCA-related ischemic events, including permanent blindness, stroke, myocardial infarction, and ischemic event-related deaths. Adverse events such as major bleeding and death caused by a bleeding event will be assessed. DISCUSSION: GCA-related ischemic events are catastrophic, sudden, often irreversible, and lead to significant morbidity. Antiplatelet agents are affordable, accessible, and could be effective for the prevention of these events. Nevertheless, the potential benefits of platelet aggregation inhibition must be weighed against their associated risk of bleeding. Assessing the efficacy and safety of antiplatelet therapy in GCA is therefore clinically important. SYSTEMATIC REVIEW REGISTRATION: Our systematic review protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO, registration number CRD42023441574.

In the next decade, the US anticipates a rapid increase in the older adult population, who also face an increased risk for disease. To reduce this risk, research should explore increasing intake of nutrient-dense foods and prepared meals that include dairy foods and utilize novel food processing that better retain nutrients. This study identified attributes that older adults (age = 65+) desire in dairy-rich ready-to-eat breakfasts and desserts, two meals important in healthy aging. Two online choice-based conjoint analysis surveys were fielded (one for breakfast and one for dessert) to determine desirable attributes amongst respondents (breakfast n = 211; dessert n = 300). Breakfast concepts included protein source, primary ingredient, type of dairy, and health claim. Dessert concepts included primary flavor, primary sweetener, type of inclusion, and health claim. Breakfast results revealed the desirable attributes included "no meat" (utility value [UV] = 0.138), "eggs" (UV = 0.384), "cheese" (UV = 0.034), and "good source of fiber" (UV = 0.163). Two consumer clusters were identified with cluster 1 (n = 151) desiring "red meat" as the protein source and cluster 2 (n = 60) preferring "no meat." The majority of respondents (86%) indicated a willingness to consume foods processed with a novel technique. For the dessert meals, desirable attributes were "chocolate flavor" (UV = 0.638), "sugar" (UV = 0.859), "fruit inclusions" (UV = 0.522), and "heart-healthy" (UV = 0.453). Dessert consumer cluster 1 (n = 145) desired chocolate desserts sweetened with sugar, whereas cluster 2 (n = 155) desired vanilla desserts sweetened with honey. Participants who preferred oral manipulation of food via "smooshing" expressed a higher liking for desserts with no inclusions. These results provide insight for future product development for older adults involving dairy products or novel processing techniques. PRACTICAL APPLICATIONS: This study shows that both sensory attributes and health claims are important considerations when developing ready to eat meals for older adults. For breakfast, providing a vegetarian option is important while for desserts, both chocolate and vanilla remain popular options.

Salmonella and Campylobacter are major foodborne pathogens that cause outbreaks associated with contaminated chicken liver. Proper cooking is necessary to avoid the risk of illness to consumers. This study tested the thermal inactivation of a 4-strain Salmonella cocktail and a 3-strain Campylobacter cocktail in chicken livers separately at temperatures ranging from 55.0 to 62.5°C. Inoculated livers were sealed in aluminum cells and immersed in a water bath. The decimal reduction time (D-values) of Salmonella in chicken livers were 9.01, 2.36, 0.82, and 0.23 min at 55.0, 57.5, 60.0, and 62.5°C, respectively. The D-values of Campylobacter ranged from 2.22 min at 55.0°C to 0.19 min at 60.0°C. Salmonella and Campylobacter had similar z-values in chicken livers of 4.8 and 4.6°C, respectively. Chicken livers can be heated to internal temperatures of 70.0 to 73.9°C for at least 1.6 to 0.2 s to achieve a 7-log reduction of Salmonella. Validation tests demonstrated that heating chicken livers to internal temperatures of 70.0 to 73.9°C for 2 to 0 s resulted in a reduction of Salmonella exceeding 7 logs. Collectively, these data show that Salmonella exhibits higher heat resistance than Campylobacter in chicken livers. Therefore, Salmonella could be considered as the target pathogen when designing thermal treatments or cooking instructions for liver products. These findings will aid in designing effective thermal processing for both industrial and home cooking to eliminate Salmonella and Campylobacter, ensuring consumer safety when consuming chicken liver products.

OBJECTIVE: Positive antineutrophil cytoplasmic antibodies (ANCAs) may occur in the setting of interstitial lung disease (ILD), with or without ANCA-associated vasculitis (AAV). We aim to compare the characteristics and clinical course of patients with ILD and positive ANCA (ANCA-ILD) to those with negative ANCA. METHODS: We performed a single-center retrospective cohort study from 2018 to 2021. All patients with ILD and ANCA testing were included. Patient characteristics (symptoms, dyspnea scale, and systemic AAV), test results (pulmonary high-resolution computed tomography and pulmonary function tests), and adverse events were collected from electronic medical records. Descriptive statistics and the Fisher exact test were used to compare the outcomes of patients with ANCA-ILD to those with ILD and negative ANCA. RESULTS: A total of 265 patients with ILD were included. The mean follow-up duration was 69.3 months, 26 patients (9.8%) were ANCA positive, and 69.2% of those with ANCA-ILD had another autoantibody. AAV occurred in 17 patients (65.4%) with ANCA-ILD. In 29.4% of patients, AAV developed following ILD diagnosis. Usual interstitial pneumonia was the most common radiologic pattern in patients with ANCA-ILD. There was no association between ANCA status and the evolution of dyspnea, diffusing capacity of the lungs for carbon monoxide, and lung imaging. Forced vital capacity improved over time in 42% of patients with ANCA-ILD and in 17% of patients with negative ANCA (P = 0.006). Hospitalization occurred in 46.2% of patients with ANCA-ILD and in 21.8% of patients with negative ANCA (P = 0.006). Both groups had similar mortality rates. CONCLUSION: Routine ANCA testing should be considered in patients with ILD. Patients with ANCA-ILD are at risk for AAV. More research is required to better understand and manage patients with ANCA-ILD.
RESUMEN
Previous research has suggested that the impact of smoke affected wines require human evaluation due to in-mouth changes in perception, perhaps associated with saliva. Smoke affected wines (n = 36) from three major wine growing regions in the US were sourced from commercial wineries. A subset of these wines (n = 7) were evaluated by a consumer panel (n = 57) and electronic tongue (e-tongue) to determine the influence of saliva in the sensory profile. Consumers assessed the wines for aroma and other sensory attributes, before and after individual saliva addition. Pooled saliva from consumers was used to treat all wines obtained (n = 36) and then analyzed using the e-tongue. Results showed that saliva did not significantly alter the overall aroma, other than fruity or woody aroma liking by consumers (p > .05). However, the presence of saliva significantly lowered overall liking in both red and white wines that were affected by smoke (p ≤ .05). Consumers rated the subset of smoke affected wines below the "might purchase" category, indicating these wines were not considered acceptable by consumers. When individual pairs of smoke affected wines (before and after saliva additions) were assessed using the e-tongue, the device was able to differentiate the pairs, validating potential usefulness to discern wine changes, though the discrimination indices were moderate to low (68.8% to 11.9%). Based on these data, in human ratings of the aroma and appearance of smoked affected wines, saliva decreased overall liking, and this was somewhat distinguishable by e-tongue analysis.
RESUMEN
Wine faults threaten brand recognition and consumer brand loyalty. The objective of this study was to compare the acuteness of e-tongue and human sensory evaluation of wine fault development in Riesling wine over 42 days of storage. Riesling wines uninoculated (control) or inoculated with 104 CFU/mL cultures of Wickerhamomyces anomalus, Acetobacter aceti, Lactobacillus brevis, or Pediococcus parvulus were assessed every 7 days with the e-tongue and a rate-all-that-apply (RATA) sensory panel. After 7 days of storage, the e-tongue detected differences in all four wine spoilage microorganism treatments, compared to control wine, with discrimination indices over 86%. The RATA sensory panel detected significant differences beginning on day 35 of storage, 28 days after the e-tongue detected differences. This study showed that the e-tongue was more sensitive than the human panel as a detection tool, without sensory fatigue. PRACTICAL APPLICATION: This research is useful for winemakers seeking additional instrumental methods in the early detection of wine faults. Given the results of this study, the e-tongue can be a useful tool for detecting early chemical changes in white wines that have undergone microbial spoilage, providing winemakers with time to mitigate faults before they surpass sensory thresholds.

BACKGROUND: Psychosocial traumatisation associated with giving birth, can occur in those present with the woman giving birth, a phenomenon known as vicarious trauma. It has been identified that there are currently no interventions available for midwifery students who have experienced vicarious trauma following difficult birth experiences. OBJECTIVE: To explore whether the counselling intervention developed by Gamble et al. (2005), can be adapted for midwifery students to be appropriately and feasibly used as a counselling intervention with peers who have experienced midwifery practice-related vicarious trauma. DESIGN: Interpretive descriptive methodology. SETTING: This study was set at two Australian universities from which pre-registration midwifery courses are delivered. PARTICIPANTS: The work of reviewing the original tool and adapting it for use by and with midwifery students associated with this project was conducted by a key stakeholder group of seven representative midwifery students and five midwifery academics. METHODS: Ethics were approved. Data were collected via one face to face and two online conversations using the Microsoft Teams™ platform. Reflexive Thematic analysis were applied to revise the tool following each round of data collection and to finalise the adaptation of the intervention for its new intended purpose. RESULTS: The Midwifery Student Peer Debriefing Tool is presented as a six-step intervention that guides the midwifery student through a process of debriefing with their peer. The feasibility of the tool resulted in an overarching theme labelled "I want this to mean something" and captures the therapeutic power of peer debriefing toward a meaningful outcome that fostered growth, and a deeper understanding of the profession. CONCLUSION: Vicarious trauma is widely recognised as a core reason for midwives and midwifery students leaving the workforce. The peer debriefing tool helps midwifery students move through the process of recovering from adversity but also fostered learnings about midwifery practice and the profession.

This study employed a home-use test to explore the sensory perception and evoked emotions of older adults in the assessment of chicken pasta meals with different salt concentrations. Ready-to-eat (RTE) meals with three salt levels (100%, 75%, and 50%) and two treatments-with and without added herbs-were tested. Multiple sensory attributes and overall meal liking were evaluated by participants (n = 54; 60-86 years of age) with hedonic and just-about-right scores. Twenty-five food-evoked emotions were also tested. Sensory results suggested a 50% salt reduction is possible with minimal impact on the overall liking, while a 25% salt reduction did not affect the saltiness and flavor liking of the meals. Herb addition positively impacted the aroma, flavor, and spiciness liking of the meals. The emotions that differed (p < 0.05) among meals were active, aggressive, bored, calm, happy, and wild, with the meals with herbs added eliciting more positive emotions. A questionnaire elicited information about participants' interest in healthy eating, food technology neophobia, and picky behaviors to determine the influence of these factors on participants' salt consumption habits. Sensory acceptance data combined with questionnaires explored what influenced this group of older adults in their acceptance of and interest in RTE meals.
RESUMEN
This study used data from consumer testing, descriptive analysis (DA), and preference mapping to determine the sensory characteristics of pear cultivars from two harvest seasons in the Pacific Northwest (PNW). A trained sensory panel (n = 10) used generic DA to evaluate multiple sensory modalities of 22 pear cultivars. Six pears from summer and six from winter season were evaluated by consumers (n = 219) to assess their liking of different attributes. Results of the DA showed the trained panel significantly discriminated the summer and winter pears on most of the sensory modalities. To identify the attributes driving consumer acceptability, external preference mapping was applied. Attributes such as pear aroma, pear flavor, sweet, sour, and juicy were the most contributory attributes to the liking of the summer pears. Conversely, fermented aroma, stemmy-woody aroma, fermented flavor, stemmy-woody flavor, and grainy-gritty attributes were associated with a reduction in consumer liking. Summer cultivars, "Bartlett," coded pear 573, and "Seckel" had the broadest preference, satisfying 60% to 80% of the consumers. Seventy-five percent of the consumers identified winter cultivars "Comice" and "Paragon" as the most appealing. Overall, cluster analysis showed that different pears appeal to different types of consumers; however, summer cultivars like "Bartlett" and "Seckel" and winter cultivars like "Comice" and "Paragon" would appeal to the greatest number of consumers in the PNW market. PRACTICAL APPLICATION: Sensory attributes like pear flavor, sweet, and juicy, were important drivers of liking for pear consumers in the Pacific Northwest. These results should prove useful to pear growers and marketers to increase pear consumption in the United States.

INTRODUCTION/OBJECTIVES: To assess and compare the performance of the giant cell arteritis probability score (GCAPS), Ing score, Bhavsar-Khalidi score (BK score), color Doppler ultrasound (CDUS) halo count, and halo score, to predict a final diagnosis of giant cell arteritis (GCA). METHOD: A prospective cohort study was conducted from April to December 2021. Patients with suspected new-onset GCA referred to our quaternary CDUS clinic were included. Data required to calculate each clinical and CDUS probability score was systematically collected at the initial visit. Final diagnosis of GCA was confirmed clinically 6 months after the initial visit, by two blinded vasculitis specialists. Diagnostic accuracy and receiver operator characteristic (ROC) curves for each clinical and CDUS prediction scores were assessed. RESULTS: Two hundred patients with suspected new-onset GCA were included: 58 with confirmed GCA and 142 without GCA. All patients with GCA satisfied the 2022 ACR/EULAR classification criteria. A total of 5/15 patients with GCA had a positive temporal artery biopsy. For clinical probability scores, the GCAPS showed the best sensitivity (Se, 0.983), whereas the BK score showed the best specificity (Sp, 0.711). As for CDUS, a halo count of 1 or more was found to have a Se of 0.966 and a Sp of 0.979. Combining concordant results of clinical and CDUS prediction scores showed excellent performance in predicting a final diagnosis of GCA. CONCLUSION: Using a combination of clinical score and CDUS halo count provided an accurate GCA prediction method which should be used in the setting of GCA Fast-Track clinics. Key Points ⢠In this prospective cohort of participants with suspected GCA, 3 clinical prediction tools and 2 ultrasound scores were compared head-to-head to predict a final diagnosis of GCA. ⢠For clinical prediction tools, the giant cell arteritis probability score (GCAPS) had the highest sensitivity, whereas the Bhavsar-Khalidi score (BK score) had the highest specificity. ⢠Ultrasound halo count was both sensitive and specific in predicting GCA. ⢠Combination of a clinical prediction tool such as the GCAPS, with ultrasound halo count, provides an accurate method to predict GCA.

Plant-based meat analog products, including those produced by extrusion processing, have become increasingly popular. Complete comprehension of the texturization mechanism and the formation of fibrousness would help improve existing products and extend the variety of plant sources used. Therefore, this study aimed to provide improved insight into the mechanism of texturization during the processing of high-moisture meat analog (HMMA) products. Blends with different wheat and pea protein ratios (100:0, 80:20, 60:40, 40:60, 20:80, and 0:100 wheat:pea) were extruded at a screw speed of 400 rpm, two different moisture contents (50% and 55%), and a feed rate of 90 g/min using a co-rotating twin-screw extruder. Extrudates were analyzed for their texture, free sulfhydryl groups, disulfide bonds, and solubility in different extractants relative to the raw ingredient blends. In addition, a sensory analysis was conducted using the rapid and cost-effective "rate-all-that-apply" (RATA) methodology. The interplay between the two protein types had synergistic effects on the system parameters torque, pressure, and specific mechanical energy, as well as on some textural and sensory parameters. Molecular analyses were not influenced by the interplay between wheat and pea protein as the molecular analyses followed linear trends with the pea inclusion level. Analysis of protein solubility suggests that the texturization mechanism differs slightly depending on the protein type. It is suggested that the texturization of wheat protein depends highly on disulfide bonds, whereas the texturization of pea protein relies on the combination of disulfide bonds and non-covalent interactions. Additionally, RATA was found to be a valuable tool for HMMA products.

Developing new food products for children is challenging, particularly in vulnerable groups including children with Down syndrome (DS). Focusing on children with DS, the aim of this study was to study the influence of parent liking on acceptance of food products by children with DS and demonstrate the influence of food sensory properties on indicators of food acceptance, food rejection, and challenging eating behaviours. Children (ages 1158 months) with DS (n = 111) participated in a home use test evaluating snack products with varying sensory properties as profiled by a trained sensory panel. Parents recorded their children's reactions to each food product; trained coders coded videos for eating behaviours. To understand the influence of each sensory modality on eating behaviour, ordered probit regression models were run. Results found a significant correlation between the parent liking and overall child disposition to the food (p < 0.05). From the regression analysis, the inclusion of all food sensory properties, including texture, flavour, taste, product shape and size, improved the percentage of variance explained in child mealtime behaviours and overall disposition over the base model (containing no sensory modalities), with texture having the largest influence. Overstuffing the mouth, a challenging eating behaviour, was most influenced by product texture (children ≥ 30 months), and product texture and size (children < 30 months). In both age groups, coughing/choking/gagging was most influenced by food texture and was associated with a product that was grainy and angular (sharp corners). In both age groups, product acceptance was associated with a product that was dissolvable, crispy, and savoury while rejection was associated with a dense, gummy and fruity product. These results suggest that a dissolvable, crispy texture, with a cheesy or buttery flavour are the sensory properties important in a desirable flavoured commercial snack product for children with DS; however, overall disposition must be balanced against mouth overstuffing.

OBJECTIVE: Takayasu arteritis (TA) leads to stenotic disease. Aneurysmal lesions are rarer. This study assessed the main characteristics of aneurysmal disease in a Canadian cohort of patients with TA. METHODS: This monocentric retrospective study included patients with TA followed at the Mount Sinai Hospital Vasculitis Clinic in Toronto. Diagnosis of TA was based on clinical findings and/or satisfied the 1990 American College of Rheumatology classification criteria. RESULTS: Seventy-four patients were included. At any time, aneurysmal disease was found in 23 (31%) patients. Median disease duration was 9.0 (IQR 7.0-19.0) years. Prior hypertension (P = 0.02), fever (P = 0.04), and seizure disorders (P = 0.03) were more common. Limb claudication was less frequent (P = 0.01). Persistent and/or new aneurysms were demonstrated in 22/23 patients at follow-up. Thoracic aorta aneurysm (13/22) was most common, followed by abdominal aorta (8/22), subclavian (7/22), and carotid (6/22) artery disease. Aortic valve regurgitation was more frequent (9/23 vs 3/48; P = 0.001). Twenty-one patients had been treated with glucocorticoids (median 6.1 years [IQR 3.7-8.1]). Methotrexate, azathioprine, and leflunomide were repeatedly used. Infliximab (7/23) was used more often (P = 0.04), whereas tocilizumab was received by only 4 patients with aneurysmal disease (P = 0.01). Patients with aneurysms suffered more frequent relapses (2.0 [IQR 0.0-4.0] vs 1.0 [IQR 0.0-2.0], P = 0.04). CONCLUSION: Aneurysmal disease was found in a significant proportion of patients with TA. Given that aneurysms may carry a risk of rupture, and are associated with a higher rate of relapse, this finding should be reported systematically in TA studies.

Parental behaviours influence food acceptance in young children, but few studies have measured these behaviours using observational methods, especially among children with Down syndrome (CWDS). The overall goal of this study was to understand parent feeding practices used during snack time with young CWDS (N = 111, aged 11-58 months). A coding scheme was developed to focus on feeding practices used by parents of CWDS from a structured home-use test involving tasting variously textured snack products. Behavioural coding was used to categorise parental feeding practices and quantify their frequencies (N = 212 video feeding sessions). A feeding prompt was coded as successful if the child ate the target food product or completed the prompt within 20 s of the prompt being given without a refusal behaviour. CWDS more frequently consumed the test foods and completed tasks in response to Autonomy-Supportive Prompts to Eat (49.3%), than to Coercive-Controlling Prompts to Eat (24.2%). By exploring the parent-CWDS relationship during feeding, we can identify potentially desirable parent practices to encourage successful feeding for CWDS. Future research should build upon the knowledge gained from this study to confirm longitudinal associations of parent practices with child behaviours during feeding.

With the growing population of older adults, a deeper understanding of their food choice and acceptance is vital to improving older adult dietary intake. The objectives of this study were to: (1) determine acceptance of three ready-to-eat (RTE) meals developed for older adults (age = 60+); (2) characterize the oral health status and food choices of these older adults and relate these data to meal acceptance. Participants (n = 52; average age = 71.7) completed an initial session that evaluated oral health and sensory perception followed by a home-use test of three RTE meals developed from a previous conjoint analysis study: teriyaki chicken with rice, marinated tofu and carrots, and vegetable ratatouille. Sensory evaluation measured liking of various meal components. Participant food choices were evaluated with the Food Choice Questionnaire (FCQ). Few participants suffered from reduced sensory ability; all had good quality oral health. Sensory evaluations revealed that the marinated tofu meal was liked significantly less than the other two meals (p < 0.0001). FCQ results clustered participants into two clusters; the responses of Cluster 1 were significantly higher for 29 of the 36 items (p < 0.05). The factors of greatest average importance were sensory appeal (4.6), health (4.3), and price (3.9) in Cluster 1 (n = 30) and sensory appeal (3.8), health (3.6), and weight control (3.2) in Cluster 2 (n = 20). Sensory appeal and health were significantly more important (p < 0.0001) to Cluster 1. Results of this study suggest that sensory appeal and health greatly contribute to food choice which was reflected in the sensory acceptance of the RTE meals. PRACTICAL APPLICATION: Older adults may suffer from sensory loss, but sensory appeal of food is still greatly important to them. Healthy and nutritious food is also important to older adult food choice. Food products developed for older adults should be formulated to provide both nutrition and a pleasant sensory experience, while also keeping price and convenience in mind.

The crewed suborbital and space flights launched by private companies over the past three years have rejuvenated public interest in space travel, including space tourism. Ready-to-eat meals (MREs) are the main source of nutrients and energy for space travelers. It is critical that those meals are free of bacterial and viral pathogens and have adequate shelf life. The participation of private companies in space programs will create new opportunities and demand for high-quality and microbiologically safe MREs for future space travels. In this article, we provide a brief review of nutrition and energy requirements for human activities in space. We discuss the general thermal processing requirements for control of bacterial and viral pathogens in MREs and introduce advanced thermal preservation technologies based on microwaves for production of MREs with different shelf-lives under various storage conditions. We also present the latest advancements in the development of polymer packaging materials for quality preservation of thermally stabilized MREs over extended storage. Finally, we recommend future research on issues related to the sensory quality of specially formulated MREs, microbial safety of dried foods that complement high moisture MREs, and food package waste management in future space missions.
RESUMEN
OBJECTIVE: In 2020, the Canadian Vasculitis Research Network (CanVasc) published their updated recommendations for the management of ANCA-associated vasculitides (AAV). The current addendum provides further recommendations regarding the use of avacopan in AAV based on a review of newly available evidence. METHODS: An updated systematic literature review on avacopan (formerly, CCX168) using Medline, Embase, and the Cochrane Library was performed for publications up to September 2022. New recommendations were developed and categorized according to the EULAR grading levels, as done for previous CanVasc recommendations. A modified Delphi procedure and videoconferences were used to reach ≥80% consensus on the inclusion, wording and grading of each recommendation. RESULTS: Three new recommendations were developed. They focus on avacopan therapy indication and duration, as well as timely glucocorticoid tapering. CONCLUSION: These 2022 addended recommendations provide rheumatologists, nephrologists and other specialists caring for patients with AAV with guidance for the use of avacopan, based on current evidence and consensus from Canadian experts.
