Relationship of parental feeding practices and diet with children's diet among South Asians in Canada.

BACKGROUND: South Asian children's diets are considered unhealthy, yet the relationship with food parenting among South Asians is understudied. METHODS: In a cross-sectional study, questionnaires were administered to dyads of Canadian South Asian elementary and high school children and a parent. Relationships between parental factors (perceived responsibility, restriction, pressure to eat, monitoring, home food environment, nutrition knowledge and intake of fruits and vegetables (FV), sugary beverages (SB) and sweets and fast foods (SWFF) and children's intake of FV, SB and SWFF were assessed by linear regression adjusted for sociodemographics. Subgroup differences by children's age and acculturation were explored by interaction analysis. RESULTS: 291 children (age 9.8 ± 3.2 years) had mean daily intake frequencies of 3.1 ± 2.0 FV, 1.0 ± 0.9 SB and 2.1 ± 1.5 SWFF. Positive associations were found between parent and child intake of FV (standardized beta (ß) = 0.230, [95%CI 0.115, 0.345], p < 0.001), SB (ß = 0.136 [0.019, 0.252], p = 0.02), and SWFF (ß = 0.167 [0.052, 0.282], p = 0.005). Parental monitoring was associated with lower children's SWFF intake (ß = -0.131 [-0.248, -0.015], p = 0.03). Among those expressing less Western culture, parental SWFF intake was associated with child's SB intake (ß = 0.255 [0.085, 0.425], p = 0.004). Among those expressing less traditional culture, positive home food environment was associated with lower child SWFF intake (ß = -0.208 [-0.374, -0.042], p = 0.015). CONCLUSION: South Asian children's diets have stronger relationships with their parents' diets than with food parenting practices or nutrition knowledge, though parental monitoring was associated with lower unhealthy food intake. However, with greater acculturation, the home food environment was more important for unhealthy food intake.

Reproducibility of Symptom Sequences Across Episodes of Recurrent Anaphylaxis.

BACKGROUND: Anaphylactic reactions may present with varying levels of severity, ranging from mild multisystem involvement to severe, and sometimes fatal, anaphylaxis. The severity of anaphylaxis is variable from one reaction to the next within the same individuals. OBJECTIVE: To compare the temporal sequence of symptoms within individuals and between individuals across multiple anaphylactic reactions. METHODS: Patients were evaluated for recurrent anaphylaxis in a tertiary care allergy clinic between 2012 and 2018. At each visit, patients were asked to record the temporal sequence in which symptoms of anaphylaxis appeared. These data were recorded at each visit and retrieved through retrospective chart review. Patients with a history of ≥2 anaphylactic reactions were included; those with anaphylaxis due to multiple allergens were excluded. The Fleiss Kappa method was used to assess reproducibility of the order of appearance of specific symptoms during anaphylaxis within individual patients and between individuals with similar triggers. RESULTS: The mean patient age was 35.6 years (standard deviation = 13.9; range: 1-68 years); 113 of 149 (76%) patients were female. The mean Fleiss Kappa reproducibility score within individuals was 0.94, 5th percentile was 0.53, and 95th percentile was 1.0. The mean Kappa score between individuals was -0.03 (range, -0.14 to 0.05). Among the 16 of 149 patients who recorded reactions of varying severity grades, the mean within-patient Kappa score was 0.96. CONCLUSION: Individual patients experience reproducibly stereotypic anaphylactic reactions over time, which are unique to a given patient, irrespective of the cause of anaphylaxis, including foods, medications, mast cell disorders, and idiopathic anaphylaxis. In contrast, symptom sequences during anaphylaxis are not reproducible between individuals.

Improvement in Hematology Interprofessional Care: Simulation With an Emphasis on Collaboration.

Introduction: For many training programs, including hematology, there are limited structured opportunities to practice collaboration as a competency. Training is often limited to ad hoc interactions during clinical rotations. Accordingly, there is further need for immersive and standardized collaboration educational programs. This pilot study explored simulation for developing and assessing collaboration competency among hematology residents. Methods: Two standardized simulation center scenarios were developed that required residents to work in interprofessional teams. The objectives were to develop collaboration competence and confidence through experiential learning and facilitated reflection. Team members included education and simulation experts as well as hematology nurses as embedded participants. Case 1 presented a 72-year-old male with stage 4 lymphoma experiencing shortness of breath during a rituximab infusion. Case 2 presented a 68-year-old male who suffered a provoked pulmonary embolism. Both cases utilized a simulated clinic space. Pre, post, and 3-month questionnaires (self-assessed collaboration competency and simulation evaluation) were completed. Each session included structured debriefing with facilitated reflection focused on collaboration. Results: Seven senior hematology subspecialty residents participated. Despite residents entering the simulation cases with confidence in collaboration, higher collaboration confidence ratings were observed on postsimulation questionnaires (8.2 vs. 7.6 on a 10-point Likert scale). Residents demonstrated awareness of appropriate collaboration skills, but at times failed to implement knowledge into action. Facilitated reflection during the debrief helped residents critique their collaboration performance and develop improvement plans. Discussion: Simulation is a promising tool for teaching and assessing collaboration within hematology training.

Efficacy of Omalizumab in Indolent Systemic Mastocytosis.

BACKGROUND: Systemic mastocytosis (SM) comprises a heterogeneous group of disorders characterized by the proliferation of clonal mast cells in skin and various internal organs. Omalizumab is an established, labelled therapy for allergic asthma and chronic urticaria, but its experience in the efficacy of SM is limited. METHODS: A retrospective analysis of 6 patients diagnosed with indolent SM treated with omalizumab at St. Michael's Hospital between 2009 and 2018 is described. Reported frequency of anaphylaxis, baseline and follow-up tryptase levels, and SM-related symptoms were captured to measure the control of the disease. RESULTS: Of the 5 patients who had experienced unprovoked anaphylaxis prior to treatment with omalizumab, 3 had no further episodes of anaphylaxis following initiation of omalizumab, while the remaining 2 patients had milder multisystem reactions. Significant improvement in cutaneous symptoms was also observed. CONCLUSION: These data suggest that omalizumab provides benefit to patients with SM who remain highly symptomatic in spite of treatment with conventional therapies.
