Perceptions and Experiences of People with Obesity and Type 2 Diabetes Around Appetite and Eating Behaviors: A Qualitative Study.

INTRODUCTION: Chronic weight management and treatments for type 2 diabetes (T2D) involve a combination of lifestyle-based (diet, exercise) and pharmaceutical interventions. In people with obesity or T2D, understanding the impact of drivers/triggers on appetite and eating behaviors can be crucial to successful medical management. This study aimed to characterize perceptions and experiences regarding appetite and eating behaviors among people with obesity or T2D and identify drivers/triggers of food choices. METHODS: This non-interventional, cross-sectional, qualitative study utilized semi-structured concept elicitation interviews to explore the perceptions of people with obesity and/or T2D around appetite, eating behaviors and drivers/triggers of food choices. Adult US residents (≥ 18 years) with stable body weight (± 5 kg) in the 3 months preceding participation were included in the study. RESULTS: Forty-five participants (obesity: n = 15; overweight: n = 10; T2D: n = 20) were interviewed. Interviews were audio-recorded and transcribed verbatim for analysis. A subset of participants described eating behaviors on smartphone-based app tasks over 5 days. Most (> 96%) discussed the influence of hunger, cravings and satiety on food choices. Participants identified 22 drivers/triggers (including health, 95.6%; culture/heritage, 93.3%; location, 91.1%; stress, 88.8%). Participants also discussed associations between drivers/triggers and eating behavior concepts (appetite, hunger, cravings, satiety, motivation/determination). A conceptual model illustrating eating behavior concepts and related drivers/triggers was developed. The concept elicitation interviews identified a multitude of drivers and triggers and characterized the association of such drivers/triggers with seven core patient-reported concepts encompassing eating behaviors. CONCLUSION: The findings build upon existing models of factors influencing food choices. Findings confirm prior research regarding impact of drivers/triggers on food choice in people with obesity and T2D and indicate underlying disease state does not appear to influence eating behaviors in people with stable body weight.

Community-based evaluation of immigrant tuberculosis screening using interferon γ release assays and tuberculin skin testing: observational study and economic analysis.

BACKGROUND: UK tuberculosis (TB) notifications are rising due to disease in the immigrant population. National screening guidelines have been revised but cost-effectiveness analyses are hampered by the lack of data on the comparative performance of tuberculin skin tests (TSTs) and interferon γ release assays (IGRAs) in immigrants. METHODS: Three-way evaluation of TSTs and two IGRAs (QuantiFERON Gold in-tube (QFN-GIT) and T-SPOT.TB) in immigrants aged ≥16 years to quantify test positivity, concordance and factors associated with positivity. Yields were computed at different incidence thresholds and the relative cost-effectiveness of screening was estimated using different latent TB infection (LTBI) screening modalities at varying incidence thresholds with or without port-of-arrival chest x-ray (CXR). RESULTS: 231 immigrants were included; median age 29 (IQR 24-37). TSTs were accepted by 80.9%, read in 93.5% and 30.3% were positive - QFN-GIT and T-SPOT.TB positive in 16.6% and 22.5% respectively. Positive TSTs, QFN-GIT and T-SPOT.TB were independently associated with increasing TB incidence in immigrants' countries of origin (p=0.007, 0.007, 0.037 respectively). Implementing current guidance (threshold 40/100 000 per year) would identify 98-100% of LTBIs (depending on test) but entail testing 97-99% of the cohort; screening at 150/100 000 per year would identify 49-71% of LTBIs but only entail screening half the cohort. The two most cost-effective screening strategies were no port-of-entry chest radiography and screen with single-step QFN-GIT at 250/100 000 per year (incremental cost-effectiveness ratio (ICER)) £21 565.3/case averted); and no port-of-entry CXR and screen with single-step QFN-GIT at 150/100 000 per year (averted additional 7.8 TB cases; ICER £31 867.1/case averted). CONCLUSIONS: UK immigrant screening could cost-effectively and safely eliminate mandatory CXR on arrival by emphasising systematic screening for LTBI with single-step IGRA. Intermediate incidence thresholds balance the need to identify as many imported LTBIs as possible against limited service capacity.

The effect of palliative daycare on hope: a comparison of daycare patients with two control groups.

BACKGROUND: Despite expansion in palliative daycare services, research has not demonstrated an improvement in patient outcomes. This study aimed to determine the effect of palliative daycare on hope. METHODS: This was a prospective cohort study that compared three groups of patients: a daycare group and two control groups, one recruited before daycare opened and a matched comparison group. Patients were interviewed at baseline and at two follow-ups using the Herth Hope Index. RESULTS: In all, 22 daycare patients completed a baseline interview (T1); 12 a second (T2); and 9 a third (T3). Corresponding numbers were: before group (56, 34, 24) and matched group (49, 29, 19). An independent samples t-test confirmed a significant difference between the groups from T1 to T2 (mean difference=3.20, p=0.007), with the daycare group experiencing an increase in hope not seen in the other groups. However, this was not maintained. CONCLUSION: Daycare may effect an initial improvement in hope. The study suffered from attrition and the sample was small. Further robust evaluation of daycare is needed.
